Geo-Oculus is a GEO-based Earth observation mission studied by Astrium for ESA in 2008-2009 to complement the Sentinel missions, the space component of the GMES (Global Monitoring for Environment & Security). Indeed Earth imaging from geostationary orbit offers new functionalities not covered by existing LEO observation missions, like real-time monitoring and fast revisit capability of any location within the huge area in visibility of the satellite. This high revisit capability is exploited by the Meteosat meteorogical satellites, but with a spatial resolution (500 m nadir for the third generation) far from most of GMES needs (10 to 100 m). To reach such ground resolution from GEO orbit with adequate image quality, large aperture instruments (> 1 m) and high pointing stability (<< 1 μrad) are required, which are the major challenges of such missions. To address the requirements from the GMES user community, the Geo-Oculus mission is a combination of routine observations (daily systematic coverage of European coastal waters) with "on-demand" observation for event monitoring (e.g. disasters, fires and oil slicks). The instrument is a large aperture imaging telescope (1.5 m diameter) offering a nadir spatial sampling of 10.5 m (21 m worst case over Europe, below 52.5°N) in a PAN visible channel used for disaster monitoring. The 22 multi-spectral channels have resolutions over Europe ranging from 40 m in UV/VNIR (0.3 to 1 μm) to 750 m in TIR (10-12 μm).

The European Union Digital Elevation Model (EU-DEM) is a relatively new, hybrid elevation product, principally based on SRTM DEM and ASTER GDEM data, but also on publically available Russian topographic maps for regions north of 60° N. More specifically, EU-DEM is a Digital Surface Model (DSM) over Europe from the Global Monitoring for Environment and Security (GMES) Reference Data Access (RDA) project - a realisation of the Copernicus (former GMES) programme, managed by the European Commission/DG Enterprise and Industry. Even if EU-DEM is indeed more reliable in terms of elevation accuracy than its constituents, it ought to be noted that it is not representative of the original elevation measurements, but is rather a secondary (mathematical) product. Therefore, for specific applications, such as those of geomorphological interest, artefacts may be induced. To this end, the purpose of this paper is to investigate the performance of EU-DEM for geomorphological applications and compare it against other available datasets, i.e. topographic maps and (almost) global DEMs such as SRTM, ASTER-GDEM and WorldDEM™. This initial investigation is carried out in Central Macedonia, Northern Greece, in the vicinity of the Mygdonia basin, which corresponds to an area of particular interest for several geoscience applications. This area has also been serving as a test site for the systematic validation of DEMs for more than a decade. Consequently, extensive elevation datasets and experience have been accumulated over the years, rendering the evaluation of new elevation products a coherent and useful exercise on a local to regional scale. In this context, relief classification, drainage basin delineation, slope and slope aspect, as well as extraction and classification of drainage network are performed and validated among the aforementioned elevation sources. The achieved results focus on qualitative and quantitative aspects of automatic geomorphological feature extraction from EU-DEM at a water basin level, with the use of Geographical Information Systems (GIS).

2013-04-01

This paper describes GMES, a free Python package for solving Maxwell’s equations using the finite-difference time-domain (FDTD) method. The design of GMES follows the object-oriented programming (OOP) approach and adopts a unique design strategy where the voxels in the computational domain are grouped and then updated according to its material type. This piecewise updating scheme ensures that GMES can adopt OOP without losing its simple structure and time-stepping speed. The users can easily add various material types, sources, and boundary conditions into their code using the Python programming language. The key design features, along with the supported material types, excitation sources, boundary conditions and parallel calculations employed in GMES are also described in detail.

Bippus, Gabriele; Nagler, Thomas

2013-04-01

The main objectives of the project "CryoLand - GMES Service Snow and Land Ice" are to develop, implement and validate services for snow, glaciers and lake and river ice products as a Downstream Service within the Global Monitoring for Environment and Security (GMES) program of the European Commission. CryoLand exploits Earth Observation data from current optical and microwave sensors and of the upcoming GMES Sentinel satellite family. The project prepares also the basis for the cryospheric component of the GMES Land Monitoring services. The CryoLand project team consists of 10 partner organisations from Austria, Finland, Norway, Sweden, Switzerland and Romania and is funded by the 7th Framework Program of the European Commission. The CryoLand baseline products for snow include fractional snow extent from optical satellite data, the extent of melting snow from SAR data, and coarse resolution snow water equivalent maps from passive microwave data. Experimental products include maps of snow surface wetness and temperature. The products range from large scale coverage at medium resolution to regional products with high resolution, in order to address a wide user community. Medium resolution optical data (e.g. MODIS, in the near future Sentinel-3) and SAR (ENVISAT ASAR, in the near future Sentinel-1) are the main sources of EO data for generating large scale products in near real time. For generation of regional products high resolution satellite data are used. Glacier products are based on high resolution optical (e.g. SPOT-5, in the near future Sentinel-2) and SAR (TerraSAR-X, in the near future Sentinel-1) data and include glacier outlines, mapping of glacier facies, glacier lakes and ice velocity. The glacier products are generated on users demand. Current test areas are located in the Alps, Norway, Greenland and the Himalayan Mountains. The lake and river ice products include ice extent and its temporal changes and snow extent on ice. The algorithms for these products are in development. One major task of CryoLand is the performance assessment of the products, which is carried out in different environments, climate zones and land cover types, selected jointly with users. Accuracy assessment is done for test areas using in-situ data and very high resolution satellite data. This presentation gives an overview on the processing lines and demonstration products for snow, glacier and lake ice parameters including examples of the product accuracy assessment. An important point of the CryoLand project is the use of advanced information technology, which is applied to process and distribute snow and land ice products in near real time.

2009-04-01

Dedicated atmospheric chemistry observations from space have been made for over 30 years now, starting with the SBUV and TOMS measurements of the ozone layer. Since then huge progress has been made, improving the accuracy of the measurements, extending the amount of constituents, and by sensing not only the stratosphere, but the last five to ten years also the troposphere. The potential to operational monitor the atmosphere, following the meteorological community, came within reach. At the same time, the importance for society of regular operational environmental measurements, related to the ozone layer, air quality and climate change, became apparent, amongst others resulting in the EU initiative Global Monitoring for Environment and Security (GMES) In order to prepare the operational missions in the context of the GMES, ESA took the initiative to further study the user requirements for the Sentinel 4 and 5 (precursor) missions. The Sentinel 4 and 5 (precursor) missions are dedicated operational missions to monitor the atmospheric composition in the 2013-2020 timeframe and onward. The user requirements for the sentinel missions focus on monitoring the atmosphere from an environmental point of view (ozone layer, air quality and climate). ESA's CAMELOT (Composition of the Atmospheric Mission concEpts and SentineL Observation Techniques) study is the follow-on study to ESA's CAPACITY study finished in 2005. The general objective of the CAMELOT study is to further contribute to the definition of the air quality and climate protocol monitoring parts of the GMES Sentinel 4 and 5 missions. Key issues in the CAMELOT study are: • trade-offs between different observation strategies (spectral ranges, polarisation, direction etc) for aerosols and several trace gases • a quantitative assessment of the requirements for spatio-temporal sampling taking into account the contamination of nadir-viewing observations by cloud • optimising several orbit scenario's (leo, inclined leo, geo or any combination) and a contribution from the user's perspective to the trade-off between different orbits. In order to address these issues a large European consortium, lead by KNMI, has been formed by 9 European institutes (KNMI, RAL, U.Leicester, SRON, FMI, BIRA-IASB, CNR-IFAC,NOVELTIS and RIU-U.Koeln). In the presentation an overview will be given of the CAMELOT study, including specific results for combined retrievals, cloud statistics for different orbit geometries and retrievals for several orbit scenarios.

2017-11-01

Multi-spectral optical filters are essential parts of spaceborne optical imagers such as the Multispectral Instrument (MSI) for the Sentinel-2 satellite in the framework of ESA's GMES programme for earth observation. In this development, Jena-Optronik is responsible for the design, manufacturing and test of the spectral filter assemblies. They are the key elements that define the spectral quality of the instrument. Besides the challenging spectral requirements straylight aspects are of crucial importance due to the close neighbourhood of the filter elements to the detector. Results will be presented of the extensive analyses and measurements that have been performed on component and assembly level to ensure the optical performance.

GMES and Down-stream Services Following User Requirements: Examples on Regional And Coastal Scale

Noehren, I.; Breitbach, G.; Schroeder, F.

2012-04-01

MyOcean as part of the Global Monitoring for Environment and Security (GMES) services provides information on the state of the oceans on a regular basis. The products are delivered on a global as well as on a regional scale like EU, covering the physical state of the ocean and primary ecosystem parameters. For local or coastal scales these Core Services very often do not meet the requirements of the potential end-user who needs information on e. g. marine safety, oil spills, marine resources and coastal management. For these local information needs Downstream Services derived from GMES Core Services, e.g. MyOcean products, but also directly from observation infrastructure are necessary. With Cosyna (Coastal Observation System for Northern and Arctic Seas) a national project between MyOcean and downstream services is established. The core of the project is an integrated pre-operational observation system which combines in-situ observations and remote sensing procedures with numerical models to obtain synoptic data sets of the southern North Sea and make basic infrastructure and continuous data available to the scientific community. The network provides intermediate products in terms of quality-assured time series and maps with high temporal and spatial resolution; end-users might produce their own end products. Integrated products cover processed information based on a combination of different observations and models, accompanied by instructions of use and optionally by interpretations. To enhance operational services in coastal areas improved forecasts with coupled models and data assimilation are developed in the EC funded FIELD_AC project (Fluxes, Interactions and Environment at the Land-Ocean Boundary. Downscaling, Assimilation and Coupling). The application area of the German partner is the German Bight. By means of a strong interaction with the Cosyna observational network main emphasis is laid on the user needs (e.g. of national agencies, coastal and harbour authorities, maritime service providers, marine consulting companies, etc) which are and will be addressed in different project user workshops.

Sentinel-1 is an imaging radar mission at C-band consisting of a constellation of two satellites aimed at providing continuity of all-weather day-and-night supply of imagery for user services. Special emphasis is placed on services identified in ESA's GMES service elements program and on projects funded by the European Union Framework Programmes. Three priorities (fast-track services) for the mission have been identified by user consultation working groups of the European Union: Marine Core Services, Land Monitoring and Emergency Services. These cover applications such as: - Monitoring sea ice zones and the arctic environment - Surveillance of marine environment - Monitoring land surface motion risks - Mapping of land surfaces: forest, water and soil, agriculture - Mapping in support of humanitarian aid in crisis situations. The Sentinel 1 space segment will be designed and built by an industrial consortium with Thales Alenia Space Italia as prime contractor and EADS Astrium GmbH as C-SAR instrument responsible. Data products from current and previous ESA missions including ERS-1, ERS-2 and Envisat missions form the basis for many of the pilot GMES services. Consequently Sentinel-1 data maintain data quality levels of the Agency‘s previous SAR missions in terms of spatial resolution, sensitivity, accuracy, polarization and wavelength. Nonetheless, the Sentinel-1 synthetic aperture radar (SAR) constellation represents a completely new approach to SAR mission design by ESA in direct response to the operational needs for SAR data expressed under the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The Sentinel-1 constellation is expected to provide near daily coverage over Europe and Canada, global coverage all independent of weather with delivery of radar data within 1 hour of acquisition - all vast improvements with respect to the existing SAR systems. The continuity of C-band SAR data combined with the greatly improved data provision is expected not only to support the existing key operational services but will also support the evolving user community both for operational and remote sensing science applications. The Sentinel-1 satellite carries a Synthetic Aperture Radar (SAR) instrument with four standard operational modes: Strip Map Mode, Interferometric Wide Swath Mode, Extra-wide Swath Mode and Wave Mode. Some of their important characteristics are listed below. MODE ACCESS ANGLE (DEG.) SINGLE LOOK RESOLUTION RANGE X AZIMUTH SWATH WIDTH POLARISATION STRIP MAP 20-45 5 X 5 M > 80 KM HH+HV OR VV+VH INTERFEROMETRIC WIDE SWATH > 25 5 X 20 M > 250 KM HH+HV OR VV+VH EXTRA WIDE SWATH > 20 20 X 40 M > 400 KM HH+HV OR VV+VH WAVE MODE 23 AND 36.5 20 X 5 M > 20 X 20 KM VIGNETTES AT 100 KM INTERVALS HH OR VV FOR ALL MODES RADIOMETRIC ACCURACY (3 Σ) 1 DB NOISE EQUIVALENT SIGMA ZERO -22 DB POINT TARGET AMBIGUITY RATIO -25 DB DISTRIBUTED TARGET AMBIGUITY RATIO -22 DB It is expected that Sentinel-1 be launched in 2011. Once in orbit Sentinel-1 will be operated from two centres on the ground. The Agency‘s facilities in Darmstadt, Germany will command the satellite ensuring its proper functioning along the orbit. The mission exploitation will be managed at the Agency‘s facilities in Frascati, Italy, including the planning of the acquisitions by the SAR instrument according to the mission requirements, the processing of the acquired data and the provision of the resulting products to the users. he presentation will provide an overview of the Sentinel-1 mission, the user requirements driving the mission, the status and characteristics of the technical implementation. The key elements of the mission supporting the evolving needs of the user community both in operational and remote sensing science applications will be highlighted.

2012-04-01

The EC FP7 ISTIMES project has the goal of realizing an ICT-based system exploiting distributed and local sensors for non destructive electromagnetic monitoring in order to make critical transport infrastructures more reliable and safe. Higher situation awareness thanks to real time and detailed information and images of the controlled infrastructure status allows improving decision capabilities for emergency management stakeholders. Web-enabled sensors and a service-oriented approach are used as core of the architecture providing a sys-tem that adopts open standards (e.g. OGC SWE, OGC CSW etc.) and makes efforts to achieve full interoperability with other GMES and European Spatial Data Infrastructure initiatives as well as compliance with INSPIRE. The system exploits an open easily scalable network architecture to accommodate a wide range of sensors integrated with a set of tools for handling, analyzing and processing large data volumes from different organizations with different data models. Situation Awareness tools are also integrated in the system. Definition of sensor observations and services follows a metadata model based on the ISO 19115 Core set of metadata elements and the O&M model of OGC SWE. The ISTIMES infrastructure is based on an e-Infrastructure for geospatial data sharing, with a Data Cata-log that implements the discovery services for sensor data retrieval, acting as a broker through static connections based on standard SOS and WNS interfaces; a Decision Support component which helps decision makers providing support for data fusion and inference and generation of situation indexes; a Presentation component which implements system-users interaction services for information publication and rendering, by means of a WEB Portal using SOA design principles; A security framework using Shibboleth open source middleware based on the Security Assertion Markup Language supporting Single Sign On (SSO). ACKNOWLEDGEMENT - The research leading to these results has received funding from the European Community's Seventh Framework Programme (FP7/2007-2013) under Grant Agreement n° 225663

The EU founded Field_ac project has investigated during the last three years methods and strategies for improving operational services in coastal areas. The objective has been to generate added value for shelf and regional scale predictions from GMES Marine Core Services. In this sense the experience in the Catalan Sea site has allowed to combine high-resolution numerical modeling tools nested into regional GMES services, data from intensive field campaigns or local observational networks and remote sensing products. Multi-scale coupled models have been implemented to evaluate different temporal and spatial scales of the dominant physical processes related with waves, currents, continental/river discharges or sediment transport. In this sense the experience of the Field_ac project in the Catalan Sea has permit to "connect" GMES marine core service results to the coastal (local) anthropogenic forcing (e.g. causes of morphodynamic evolution and ecosystem degradation) and will support a knowledge-based assessment of decisions in the coastal zone. This will contribute to the implementation of EU directives (e.g., the Water Framework Directive for water quality at beaches near harbour entrances or the Risk or Flood Directives for waves and sea-level at beach/river-mouth scales).

GMES Initial Operations - Network for Earth Observation Research Training (GIONET) is a Marie Curie funded project that aims to establish the first of a kind European Centre of Excellence for Earth Observation Research Training. GIONET is a partnership of leading Universities, research institutes and private companies from across Europe aiming to cultivate a community of early stage researchers in the areas of optical and radar remote sensing skilled for the emerging GMES land monitoring services during the GMES Initial Operations period (2011-2013) and beyond. GIONET is expected to satisfy the demand for highly skilled researchers and provide personnel for operational phase of the GMES and monitoring and emergency services. It will achieve this by: * Providing postgraduate training in Earth Observation Science that exposes students to different research disciplines and complementary skills, providing work experiences in the private and academic sectors, and leading to a recognized qualification (Doctorate). * Enabling access to first class training in both fundamental and applied research skills to early-stage researchers at world-class academic centres and market leaders in the private sector. * Building on the experience from previous GMES research and development projects in the land monitoring and emergency information services. * Developing a collaborative training network, through the placement of researchers for short periods in other GIONET organizations. Reliable, thorough and up-to-date environmental information is essential for understanding climate change the impacts it has on people's lives and ways to adapt to them. The GIONET researchers are being trained to understand the complex physical processes that determine how electromagnetic radiation interacts with the atmosphere and the land surface ultimately form the signal received by a satellite. In order to achieve this, the researchers have been placed in industry and universities across Europe, as well as receiving the best technical training and scientific education. This training is currently being delivered through individually supervised research, international summer schools and local training. GIONET will develop better methods for monitoring climate change, environmental disasters and land cover change. It will also lead to the development of new methods using satellite monitoring for disaster relief after landslides and floods, controlling deforestation and overseeing the protection of tropical rainforests, as well as for climate change monitoring, lake water quality measurement and coastal erosion assessment. The training program through supervised research focuses on 14 research topics (each carried out by an Early Stage Researchers based in one of the partner organization) divided in 5 main areas: * Forest monitoring: o Global biomass information systems o Forest monitoring of the Congo Basin using Synthetic Aperture Radar (SAR) o Multi-concept Earth Observation capabilities for biomass mapping and change detection: synergy of multi-temporal and multi-frequency interferometric radar and optical satellite data * Land cover and change: o Multi-scale remote sensing synergy for land process studies: from field spectrometry to airborne hyperspectral and LiDAR campaigns to radar-optical satellite data o Multi-temporal, multi-frequency SAR for landscape dynamics * Coastal zone and freshwater monitoring: o SAR-based Earth Observation in support of management of intertidal salt marsh habitats o Dynamics and conservation ecology of emergent and submerged macrophytes in Lake Balaton using airborne remote sensing o Satellite remote sensing of water quality (chlorophyll and suspended sediment) using MODIS and ship-mounted LIDAR * Geohazards and emergency response: o Methods for detection and monitoring of small scale land surface feature changes in complex crisis situations o Monitoring landslide displacements with Radar Interferometry o DINSAR/PSI hybrid methodologies for ground-motion monitoring * Climate adaptation and emergency response: o Earth Observation based analysis of regional impact of climate change induced water stress patterns fuelling human crisis and conflict situations in semi dry climate regimes o Satellite derived information for drought detection and estimation of the water balance GIONET will also cover methodologies including (i) modelling fundamental radiative processes determining the satellite signal, (ii) atmospheric correction and calibration, (iii) processing higher-order data products, (iii) developing information products from satellite data to meet user requirements, and (iv) statistical methods for assessing the quality and accuracy of data products. These methodologies will enable the researchers to develop careers in the evolving GMES (renamed to Copernicus) Services, network with the GMES community and contribute to rolling out the GMES Program. Communication skills and effective engagement with stakeholders and the public will form an integral part of the training. The Earth Observation methods developed in GIONET will benefit the economy in Europe.

The high costs to develop, launch and maintain a satellite network makes protecting the assets imperative. Attacks may be passive such as eavesdropping on the payload data. More serious threat are active attacks that try to gain control of the satellite, which may lead to the total lost of the satellite asset. To counter these threats, new satellite and ground systems are using cryptographic technologies to provide a range of services: confidentiality, entity & message authentication, and data integrity. Additionally, key management cryptographic services are required to support these services. This paper describes the key points of current satellite control and operations, that are authentication of the access to the satellite TMTC link and encryption of security relevant TM/TC data. For payload data management the key points are multi-user ground station access and high data rates both requiring frequent updates and uploads of keys with the corresponding key management methods. For secure satellite management authentication & key negotiation algorithms as HMAC-RIPEMD160, EC- DSA and EC-DH are used. Encryption of data uses algorithms as IDEA, AES, Triple-DES, or other. A channel coding and encryption unit for payload data provides download data rates up to Nx250 Mbps. The presented concepts are based on our experience and heritage of the security systems for all German MOD satellite projects (SATCOMBw2, SAR-Lupe multi- satellite system and German-French SAR-Lupe-Helios- II systems inter-operability) as well as for further international (KOMPSAT-II Payload data link system) and ESA activities (TMTC security and GMES).

There has been a long history of considering Safety, Security, and Safeguards (3S) as three functions of nuclear security design and operations that need to be properly and collectively integrated with operations. This paper specifically considers how safety programmes can be extended directly to benefit security as part of an integrated facility management programme. The discussion will draw on experiences implementing such a programme at Sandia National Laboratories’ Annular Research Reactor Facility. While the paper focuses on nuclear facilities, similar ideas could be used to support security programmes at other types of high-consequence facilities and transportation activities.

The main objective of the project GLOWASIS is to pre-validate a GMES Global Service for Water Scarcity Information. It will be set up as a one-stop-shop portal for water scarcity information, in which focus is put on: - monitoring data from satellites and in-situ sensors; - improving forecasting models with improved monitoring data; - linking statistical water data in forecasting; - promotion of GMES Services and European satellites. In European and global pilots on the scale of river catchments it combines hydrological models with in-situ and satellite derived water cycle information, as well as government ruled statistical water demand data. By linking water demand and supply in three pilot studies with existing platforms (European Drought Observatory and PCR-GLOBWB) for medium- and long-term forecasting in Europe, Africa and worldwide, GLOWASIS' information contributes both in near-real time reporting for emerging drought events as well as in provision of climate change time series. By combining complex water cycle variables, governmental issues and economic relations with respect to water demand, GLOWASIS will aim for the needed streamlining of the wide variety of important water scarcity information. More awareness for the complexity of the water scarcity problem will be created and additional capabilities of satellite-measured water cycle parameters can be promoted. The service uses data from GMES Core Services LMCS Geoland2 and Marine Core Service MyOcean (land use, soil moisture, soil sealing, sea level), in-situ data from GEWEX' initiatives (i.e. International Soil Moisture network), agricultural and industrial water use and demand (statistical - AQUASTAT, SEEAW and modelled) and additional water-cycle information from existing global satellite services. In-depth interviews with a.o. EEA and the Australian Bureau of Meteorology are taking place. GLOWASIS will aim for an open source and open-standard information portal on water scarcity and use of modern media (forums, Twitter, etc). Infrastructure of the GLOWASIS portal is set up for dissemination and inclusion of current and future innovative and integrated multi-purpose products for research & operational applications with open standards. The project has started in January 2011 and the duration is 24 months.

Security mechanism based on Hospital Authentication Server for secure application of implantable medical devices.

2014-01-01

After two recent security attacks against implantable medical devices (IMDs) have been reported, the privacy and security risks of IMDs have been widely recognized in the medical device market and research community, since the malfunctioning of IMDs might endanger the patient's life. During the last few years, a lot of researches have been carried out to address the security-related issues of IMDs, including privacy, safety, and accessibility issues. A physician accesses IMD through an external device called a programmer, for diagnosis and treatment. Hence, cryptographic key management between IMD and programmer is important to enforce a strict access control. In this paper, a new security architecture for the security of IMDs is proposed, based on a 3-Tier security model, where the programmer interacts with a Hospital Authentication Server, to get permissions to access IMDs. The proposed security architecture greatly simplifies the key management between IMDs and programmers. Also proposed is a security mechanism to guarantee the authenticity of the patient data collected from IMD and the nonrepudiation of the physician's treatment based on it. The proposed architecture and mechanism are analyzed and compared with several previous works, in terms of security and performance.

General practitioners with more positive role security and therapeutic commitment towards patients with hazardous or harmful alcohol consumption are more involved and manage more alcohol-related problems than others. In this study we evaluated the effects of our tailored multi-faceted improvement implementation programme on GPs' role security and therapeutic commitment and, in addition, which professional related factors influenced the impact of the implementation programme. In a cluster randomised controlled trial, 124 GPs from 82 Dutch general practices were randomised to either the intervention or control group. The tailored, multi-faceted programme included combined physician, organisation, and patient directed alcohol-specific implementation strategies to increase role security and therapeutic commitment in GPs. The control group was mailed the national guideline and patients received feedback letters. Questionnaires were completed before and 12 months after start of the programme. We performed linear multilevel regression analysis to evaluate effects of the implementation programme. Participating GPs were predominantly male (63%) and had received very low levels of alcohol related education before start of the study (0.4 h). The programme increased therapeutic commitment (p = 0.005; 95%-CI 0.13 - 0.73) but not role security (p = 0.58; 95%-CI -0.31 - 0.54). How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, contributed to the effect of the programme on therapeutic commitment. A tailored, multi-faceted programme aimed at improving GP management of patients with hazardous and harmful alcohol consumption improved GPs' therapeutic commitment towards patients with alcohol-related problems, but failed to improve GPs' role security. How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, both increased the impact of the programme on therapeutic commitment. It might be worthwhile to monitor proceeding of role security and therapeutic commitment throughout the year after the implementation programme, to see whether the programme is effective on short term but faded out on the longer term.

Information on snow cover and snow properties are important for hydrology and runoff modelling. Frequent updates of snow cover observation, especially for areas characterized by short-term snow dynamics, can help to improve water balance and discharge calculations. Within the GMES service element Polar View, VISTA offers a snow mapping service for Central Europe since several years [1, 2]. We outline the use of this near-real- time product for hydrological applications in Alpine environment. In particular we discuss the integration of the Polar View product into a physically based hydrological model (PROMET). This allows not only the provision of snow equivalent values, but also enhances river runoff modelling and its use in hydropower energy yield prediction. The GMES snow products of Polar View are thus used in a downstream service for water resources management, providing information services for renewable energy suppliers and energy traders.

Sentinel-5 Precursor (S-5P) will be the first of a series of atmospheric missions to be launched within the European Commission's Copernicus (former GMES) Programme. With a planned launch in 2016 and a nominal lifetime of 7 years S-5P is expected to provide continuity in the availability of global atmospheric data products between its predecessor missions SCIAMACHY (Envisat) and OMI (AURA) and the future Sentinel-4 and -5 series. The latter will comprise payload instruments on board the operational satellites MTG-S (S-4, geostationary component) and MetOp Second Generation (S-5, polar orbiting component), the first units of which will be launched in the 2020-2021 timeframe.The S-5P satellite will carry a single payload, TROPOMI (TROPOspheric Monitoring Instrument) which is jointly developed by The Netherlands and ESA. Covering spectral channels in the UV, visible, near- and short-wave infrared it will measure various key species including tropospheric/stratospheric ozone, NO2, SO2, CO, CH4, CH2O as well as cloud and aerosol parameters.

Space and the complexity of European rules and policies: The common projects Galileo and GMES—precedence for a new European legal approach?

NASA Astrophysics Data System (ADS)

Froehlich, Annette

2010-04-01

The two European flagship space projects, Galileo and GMES, clearly show that the current existing legal rules of the two organisations involved (European Union and European Space Agency) are not compatible. Moreover, it is quite impossible to implement a common project if every single organisation insists on the application of its own rules strictu sensu. Nevertheless, due to the political desire to advance these projects rapidly and to make them a success, legal obstacles were to be overcome. Consequently, recently concluded agreements between ESA and the EU-Commission concerning the financial and governmental matters of the Galileo and GMES implementation feature a new approach to cooperation between these two organisations. However, the question remains if they can be taken as precedence for a future institutionalised cooperation? It follows that the agreements have to be analysed in order to understand how a mutually acceptable agreement was reached despite the disparity in the rules of both organisations. In this regard, especially the financial decision agreement concerning Galileo in December 2007 shows a very interesting and unique way in applying EU-competition law. In the same way, the GMES-Delegation Agreement of spring 2008 is a good example of how two different legal systems can be applied to make a project success. Additionally, the reasons and arguments of both organisations have to be considered, especially once the Treaty of Lisbon will be in force. As these two main projects of the European Space Policy are characterized by the desire for a successful European cooperation, they can be regarded as an important step forward for a new legal approach. A new system emerges which could be taken into consideration for further common projects undertaken by ESA and the EU.

The GIIDA (Gestione Integrata e Interoperativa dei Dati Ambientali) project is an initiative of the Italian National Research Council (CNR) launched in 2008 as an inter-departmental project, aiming to design and develop a multidisciplinary e-infrastructure (cyber-infrastructure) for the management, processing, and evaluation of Earth and Environmental resources -i.e. data, services, models, sensors, best practices. GIIDA has been contributing to the implementation of the GEO (Group of Earth Observation) Science and Technology (S&T) roadmap by: (a) linking relevant S&T communities to GEOSS (GEO System of Systems); (b) ensuring that GEOSS is built based on state-of-the-art science and technology. GIIDA co-ordinates the CNR's digital infrastructure development for Earth Observation resources sharing and cooperates with other national agencies and existing projects pursuing the same objective. For the CNR, GIIDA provides an interface to European and international interoperability programmes (e.g. INSPIRE, and GMES). It builds a national network for dialogue and resolution of issues at varying scientific and technical levels. To achieve such goals, GIIDA introduced a set of guidance principles: • To shift from a "traditional" data centric approach to a more advanced service-based solution for Earth System Science and Environmental information. • To shift the focus from Data to Information Spatial Infrastructures in order to support decision-making. • To be interoperable with analogous National (e.g. SINAnet, and the INSPIRE National Infrastructure) and international initiatives (e.g. INSPIRE, GMES, SEIS, and GEOSS). • To reinforce the Italian presence in the European and international programmes concerning digital infrastructures, geospatial information, and the Mega-Science approach. • To apply the National and International Information Technology (IT) standards for achieving multi-disciplinary interoperability in the Earth and Space Sciences (e.g. ISO, OGC, CEN, CNIPA) In keeping with GEOSS, GIIDA infrastructure adopts a System of Systems architectural approach in order to federate the existing systems managed by a set of recognized Thematic Areas (i.e. Risks, Biodiversity, Climate Change, Air Quality, Land and Water Quality, Ocean and Marine resources, Joint Research and Public Administration infrastructures). GIIDA system of systems will contribute to develop multidisciplinary teams studying the global Earth systems in order to address the needs coming from the GEO Societal Benefit Areas (SBAs). GIIDA issued a Call For Pilots receiving more than 20 high-level projects which are contributing to the GIIDA system development. A national-wide research environmental infrastructure must be interconnected with analogous digital infrastructures operated by other important stakeholders, such as public users and private companies. In fact, the long-term sustainability of a "System of Systems" requires synergies between all the involved stakeholders' domains: Users, Governance, Capacity provision, and Research. Therefore, in order to increase the effectiveness of the GIIDA contribution process to a national environmental e-infrastructure, collaborations were activated with relevant actors of the other stakeholders' domains at the national level (e.g. ISPRA SINAnet).

Poverty alleviation programmes in India: a social audit.

PubMed

K Yesudian, C A

2007-10-01

The review highlights the poverty alleviation programmes of the government in the post-economic reform era to evaluate the contribution of these programmes towards reducing poverty in the country. The poverty alleviation programmes are classified into (i) self-employment programmes; (ii) wage employment programmes; (iii) food security programmes; (iv) social security programmes; and (v) urban poverty alleviation programmes. The parameter used for evaluation included utilization of allocated funds, change in poverty level, employment generation and number or proportion of beneficiaries. The paper attempts to go beyond the economic benefit of the programmes and analyzes the social impact of these programmes on the communities where the poor live, and concludes that too much of government involvement is actually an impediment. On the other hand, involvement of the community, especially the poor has led to better achievement of the goals of the programmes. Such endeavours not only reduced poverty but also empowered the poor to find their own solutions to their economic problems. There is a need for decentralization of the programmes by strengthening the panchayat raj institutions as poverty is not merely economic deprivation but also social marginalization that affects the poor most.

All government policies and programmes for food and nutrition security should include providing healthy food, as well as providing economic and social availability for all people. This study aimed to analyse the current situation of Iranian food and nutrition security and establish a road map towards 2021. The applied methods were situation analysis and a mixed qualitative-quantitative method. The conceptual method used for developing this national document encompassed three areas: sustainable food supply, food safety and nutrition. The outcomes of the Iranian food and nutrition security system in the past three decades include development of management infrastructure and improvement in food and nutrition security status. However, analysis of current programmes showed that there were some overlapping, intertwining and parallel works in the responsibilities of related organizations in the field of supervision of food safety (from production to supply). The national document produced as the outcome of this paper was communicated by the Iranian Ministry of Health in 2012 and has been running for 2 years. Selected ministries are responsible for implementation of 20 national programmes by the end of the 5th Economic, Social and Cultural Development Programme (2016-2011). The consensus of stakeholders by the end of the 6th Development Programme (2021) is to put all of the provinces in a safe or very safe situation in terms of food and nutrition security. The most important challenge in establishing national documents is to make them operational. This aim was achieved by an intersectoral nutrition and food security working group, which produced a general memorandum of understanding with the main organizations, the media, universities and private sector.

The GreenSeas project (Development of global plankton data base and model system for eco-climate early warning) aims to advance the knowledge and predictive capacities of how marine ecosystems will respond to global change. A main task has been to set up a data delivery and monitoring core service following the open and free data access policy implemented in the Global Monitoring for the Environment and Security (GMES) programme. A key feature of the system is its ability to compare data from different datasets, including an option to upload one's own netCDF files. The user can for example search in an in situ database for different variables (like temperature, salinity, different elements, light, specific plankton types or rate measurements) with different criteria (bounding box, date/time, depth, Longhurst region, cruise/transect) and compare the data with model data. The user can choose model data or Earth observation data from a list, or upload his/her own netCDF files to use in the comparison. The data can be visualized on a map, as graphs and plots (e.g. time series and property-property plots), or downloaded in various formats. The aim is to ensure open and free access to historical plankton data, new data (EO products and in situ measurements), model data (including estimates of simulation error) and biological, environmental and climatic indicators to a range of stakeholders, such as scientists, policy makers and environmental managers. We have implemented a web-based GIS(Geographical Information Systems) system and want to demonstrate the use of this. The tool is designed for a wide range of users: Novice users, who want a simple way to be able to get basic information about the current state of the marine planktonic ecosystem by utilizing predefined queries and comparisons with models. Intermediate level users who want to explore the database on their own and customize the prefedined setups. Advanced users who want to perform complex queries and inventory searching and compare the data in their own way or with their own models.

Systems Harmonization and Convergence - the GIGAS Approach

0.1 Background The GIGAS1 Support Action promotes the coherent and interoperable development of the GMES, INSPIRE and GEOSS initiatives through their concerted adoption of standards, protocols, and open architectures. 0.2 Preparing for Coordinated Data Access The GMES Coordinated Data Access System is under design and implementation2. This objective has motivated the definition of the interoperability standards between the contributing missions. The following elements have been addressed with associated papers submitted to OGC: The EO Product Metadata has been based on the OGC Geographic Markup Language, addressing sensor characteristics for optical, radar and atmospheric products. Collection and service discovery: an ISO extension package for CSW ebRim has been proposed. Catalogue Service (CSW): an Earth Observation extension package of the CSW ebRim has been proposed. Feasibility Analysis and Order: an Order interface control document and an Earth Observation profile of the Sensor Planning Service have been proposed. Online Data Access: an Earth Observation profile of the Web Map Services (WMS) for visualization and evaluation purposes has been proposed. Identity (user) management: the objective in the long term is to allow for a single sign-on to the Coordinated Data Access system by users registered in the various Earth Observation ground segments by providing a federated identity across participating ground segments, exploiting OASIS standards. 0.3 The GIGAS proposed harmonization approach The approach proposed by GIGAS is based on three elements: Technology watch Comparative analysis Shaping of initiatives and standards This paper concentrates on the methodology for technology watch and comparative analysis. The complexity of the GIGAS scenario involving huge systems (i.e. GEOSS, INSPIRE, GMES etc.) entails the interaction with different heterogeneous partners, each with a specific competence, expertise and know-how. 0.3.1 Technology watch The methodology proposed is based on an RM-ODP based study supported by interoperability use cases and scenarios used to derive requirements. GIGAS will monitor the INSPIRE, GMES and GEOSS evolution and analyze the requirements, the standards, the services and the architecture, the models, the processes and the consensus mechanisms with the same elements of the other systems under analysis. activities in the fields of standard development that are part of the three initiatives. This task will provide the basis for how these three initiatives will strategically support consensus and efficient standards development going forward. architecture, specifications, innovative concepts and software developments of past or ongoing FP6/FP7 research topics. The use of an RM-ODP approach is selected as: most of the architectural approaches to be compared are based on RM-ODP, it supports distributed processing, it aims at fostering interoperability across heterogeneous systems, it tries to hide distribution to systems developers. However, as most of the systems to be considered have the characteristic of a loosely-coupled network of systems and services instead of a "distributed processing system based on interacting objects", the RM-ODP concepts are tailored for the GIGAS needs. The usage of RM-ODP for GIGAS Requirements and Technology Watch is two-fold: Architectural analysis: It is performed for all projects and initiatives. Its purpose is to identify possibilities but also major obstacles for interoperability. Furthermore, it identifies the major use cases to be analysed in more detail. Use Case Implementation Analysis: It is used to describe how selected use cases of the projects and initiatives are implemented in the different architectures. Its purpose is to identify technological gaps and concrete problems of interoperability. It is performed only for selected use cases. The output of the Technology Watch is an RM-ODP based report containing parallel analysis on the same aspects on the three initiatives integrated by analysis of relevant FP6-FP7 projects and standardization activities. 0.3.2 Comparative Analysis Based on the outcomes of the previous monitoring tasks, GIGAS undertakes a comparative analysis on solutions, requirements, architecture, models, processes and consensus mechanisms used by INSPIRE, GMES and GEOSS, taking into account the inputs from the monitoring of FP6/FP7 research projects and the ongoing standardization activities. Initiative Contact Points will insure that the overall policy framework and schedules for each of the three initiatives will be factored in. The result of the Comparative Analysis includes: A list of recommendations to GEOSS, INSPIRE and GMES to be expanded and processed in depth in the following shaping phase The identification of technological gaps to be explored in the following shaping phase. Guidelines and objectives for the architectural approach within GIGAS Analysis on the schedules of the three initiatives and on the FP6/FP7 programs and standardization activities, with identification of key milestones or intervention points.

ESA Sentinel-1 Mission and Products

The global Monitoring for Environment and Security (GMES) space component relies on existing and planned space assets by European States, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), and the European Space Agency (ESA), as well as new complementary developments by ESA. The new developments are implemented in terms of five families of satellites called Sentinels. The Sentinel-1 mission is an imaging synthetic aperture radar (SAR) mission at C-band designed to supply all-weather day-and-night imagery to a number of operational Earth observation based services. Three priorities (fasttrack services) for the mission have been identified by user consultation working groups of the European Union: Marine Core Services, Land Monitoring and Emergency Services. These cover applications such as: - monitoring sea ice zones and the arctic environment, - surveillance of marine environment, - monitoring land surface motion risks, - mapping of land surfaces: forest, water and soil, agriculture, - mapping in support of humanitarian aid in crisis situations. Sentinel-1 has been designed to address medium resolution applications. It includes a main mode of operation that features a wide swath (250 km) and a medium resolution (5 m x 20 m). The two-satellite constellation offers six days exact repeat and the conflict-free operations based on the main operational mode allow exploiting every single data take. This paper describes the Sentinel-1 mission, provides an overview of the mission requirements, and presents some of the key user driven information products, the crucial requirements for operational sustainable services being continuity of data supply, frequent revisit, geographical coverage and timeliness. As data products from the Agency‘s successful ERS-1, ERS-2 and Envisat missions form the basis for many of the pilot GMES services, Sentinel-1 data products need to maintain and in some ways to improve data quality levels of the Agency‘s previous SAR missions. Based on mission analysis work in preparation of Sentinel-1, this paper presents the results of investigations on the impact of some of the new mission and system requirements (such as spatial and radiometric resolution, calibration accuracy, revisit, . . . ) on the accuracy of key information products (wind speed measurement, ship detection, flood mapping, rice crop monitoring, soil moisture measurement, forest mapping, land surface movement measurement, . . . ).

The present paper analyses the advances and challenges of the school feeding programme in Brazil (PNAE), as part of the Brazilian experience building up an integrated food and nutrition security national system. It explores the role of policy and regulatory frameworks in constructing quality service delivery and intersectoral integration. Review of PNAE and federal government technical documents and studies, legislation, minutes of meetings and official documents of the National Council of Food and Nutrition Security from 2003 to 2011. Food insecurity has decreased significantly in Brazil in the last decade, indicating that appropriate choices were made in terms of public policies and institutional arrangements, which other countries can learn from. Brazil food and nutrition security system; school feeding; school food. Brazil's integrated food and nutrition security policy approach promoted intersectorality in the food system, articulating actions to guarantee access to healthy food and to strengthen family farming. The quality of school meals has progressively improved; in particular, the availability of fruits and vegetables increased. However, national standards regarding menu composition have not yet been met. Regulations were an important factor, along with the policy approach linking food production, nutrition, health and education. Challenges are related to conflict of interests and to farmers' insufficient capacity to meet supply requirements and comply with technical procedures. Local food production, school meals and nutrition education can be linked through integrated programmes and policies, improving access to healthier foods. Government leadership, strong legislation, civil society participation and intersectoral decision making are determinant.

Soil moisture mapping using Sentinel 1 images: the proposed approach and its preliminary validation carried out in view of an operational product

The main objective of this research is to develop, test and validate a soil moisture (SMC)) algorithm for the GMES Sentinel-1 characteristics, within the framework of an ESA project. The SMC product, to be generated from Sentinel-1 data, requires an algorithm able to process operationally in near-real-time and deliver the product to the GMES services within 3 hours from observations. Two different complementary approaches have been proposed: an Artificial Neural Network (ANN), which represented the best compromise between retrieval accuracy and processing time, thus allowing compliance with the timeliness requirements and a Bayesian Multi-temporal approach, allowing an increase of the retrieval accuracy, especially in case where little ancillary data are available, at the cost of computational efficiency, taking advantage of the frequent revisit time achieved by Sentinel-1. The algorithm was validated in several test areas in Italy, US and Australia, and finally in Spain with a 'blind' validation. The Multi-temporal Bayesian algorithm was validated in Central Italy. The validation results are in all cases very much in line with the requirements. However, the blind validation results were penalized by the availability of only VV polarization SAR images and MODIS lowresolution NDVI, although the RMS is slightly > 4%.

The increased use of Field Programmable Gate Arrays (FPGAs) in critical systems brings new challenges in securing the diversely programmable fabric from cyber-attacks. FPGAs are an inexpensive, efficient, and flexible alternative to Application Specific Integrated Circuits (ASICs), which are becoming increasingly expensive and impractical for low volume manufacturing as technology nodes continue to shrink. Unfortunately, FPGAs are not designed for high security applications, and their high-flexibility lends itself to low security and vulnerability to malicious attacks. Similar to securing an ASIC’s functionality, FPGA programmers can exploit the inherent randomness introduced into hardware structures during fabrication for security applications. Physically Unclonablemore » Functions (PUFs) are one such solution that uses the die specific variability in hardware fabrication for both secret key generation and verification. PUFs strive to be random, unique, and reliable. Throughout recent years many PUF structures have been presented to try and maximize these three design constraints, reliability being the most difficult of the three to achieve. This thesis presents a new PUF structure that combines two elementary PUF concepts (a bi-stable SRAM PUF and a delay-based arbiter PUF) to create a PUF with increased reliability, while maintaining both random and unique qualities. Properties of the new PUF will be discussed as well as the various design modifications that can be made to tweak the desired performance and overhead.« less

Costs and outcomes of an intervention programme for offenders with personality disorders.

PubMed

Barrett, Barbara; Byford, Sarah

2012-04-01

The dangerous severe personality disorder programme was developed in high secure prisons and hospitals at great expense to identify and treat the most dangerous offenders with personality disorders. To evaluate whether the long-term costs of the programme are greater or less than the long-term outcomes. We used a Markov decision model with a cost-effectiveness analysis to determine the incremental cost of the programme per serious offence prevented and a cost-offset analysis to consider whether monetary benefits were greater than costs. Costs were consistently higher for the intervention programme and the cost per serious offence prevented was over £2 million, although there was some evidence that adjustments to the programme could lead to similar interventions becoming cost-effective. Little evidence was found to support the cost-effectiveness of the intervention programme for offenders with personality disorders, although delivery of the programme in a lower-cost prison would probably yield greater benefits than costs. There are frequent calls for mentally disordered offenders to be detained in secure hospitals rather than prisons; however, if reoffending remains the outcome of interest for policy makers, it is likely that the costs of detention in hospital will remain greater than the benefits for dangerous offenders with a personality disorder.

Detention in a secure forensic psychiatric hospital may inhibit engagement and recovery. Having validated the clinician rated DUNDRUM-3 (programme completion) and DUNDRUM-4 (recovery) in a forensic hospital, we set out to draft and validate scales measuring the same programme completion and recovery items that patients could use to self-rate. Based on previous work, we hypothesised that self-rating scores might be predictors of objective progress including conditional discharge. We hypothesised also that the difference between patients' and clinicians' ratings of progress in treatment and other factors relevant to readiness for discharge (concordance) would diminish as patients neared discharge. We hypothesised also that this difference in matched scores would predict objective progress including conditional discharge. In a prospective naturalistic observational cohort study in a forensic hospital, we examined whether scores on the self-rated DUNDRUM-3 programme completion and DUNDRUM-4 recovery scales or differences between clinician and patient ratings on the same scales (concordance) would predict moves between levels of therapeutic security and conditional discharge over the next twelve months. Both scales stratified along the recovery pathway of the hospital, but clinician ratings matched the level of therapeutic security more accurately than self ratings. The clinician rated scales predicted moves to less secure units and to more secure units and predicted conditional discharge but the self-rated scores did not. The difference between clinician and self-rated scores (concordance) predicted positive and negative moves and conditional discharge, but this was not always an independent predictor as shown by regression analysis. In regression analysis the DUNDRUM-3 predicted moves to less secure places though the HCR-20 C & R score dominated the model. Moves back to more secure places were predicted by lack of concordance on the DUNDRUM-4. Conditional discharge was predicted predominantly by the DUNDRUM-3. Patients accurately self-rate relative to other patients however their absolute ratings were consistently lower (better) than clinicians' ratings and were less accurate predictors of outcomes including conditional discharge. Quantifying concordance is a useful part of the recovery process and predicts outcomes but self-ratings are not accurate predictors.

Sentinel-5 Precursor (S-5P) will be the first of a series of atmospheric missions to be launched within the European Commission's Copernicus (former GMES) Programme. With the current launch window mid October - mid November 2016 and a nominal lifetime of 7 years S-5P is expected to provide continuity in the availability of global atmospheric data products between its predecessor missions SCIAMACHY (Envisat) and OMI (AURA) and the future Sentinel-4 and -5 series.S-5P will deliver unique data regarding the sources and sinks of trace gases with a focus on the lower Troposphere including the planet boundary layer. Due to its enhanced spatial, temporal and spectral sampling capabilities, as compared to its predecessors.The S-5P satellite will carry a single payload, TROPOMI (TROPOspheric Monitoring Instrument) which is jointly developed by The Netherlands and ESA. Covering spectral channels in the UV, visible, near- and short-wave infrared it will measure various key species including tropospheric/stratospheric ozone, NO2, SO2, CO, CH4, CH2O as well as cloud and aerosol parameters.The S-5P Project has successfully passed the Ground Segment Acceptance Review (GS-AR) and the satellite level Qualification Acceptance Review (QAR) in March and April 2016, respectively. Remaining pre-launch tasks focus on the detailed planning of Phase E1 activities and the training of the operations teams.

National tuberculosis programme review: experience over the period 1990-95.

Since 1990 the WHO Global Tuberculosis Programme (GTB) has promoted the revision of national tuberculosis programmes to strengthen the focus on directly observed treatment, short-course (DOTS) and close monitoring of treatment outcomes. GTB has encouraged in-depth evaluation of activities through a comprehensive programme review. Over the period 1990-95, WHO supported 12 such programme reviews. The criteria for selection were as follows: large population (Bangladesh, Brazil, China, Ethiopia, India, Indonesia, Mexico, and Thailand); good prospects of developing a model programme for a region (Nepal, Zimbabwe); or at advanced stage of implementation of a model programme for a region (Guinea, Peru). The estimated combined incidence of smear-positive pulmonary tuberculosis was 82 per 100,000 population, about 43% of the global incidence. The prevalence of infection with human immunodeficiency virus (HIV) was variable, being very high in Ethiopia and Zimbabwe, but negligible in Bangladesh, China, Nepal and Peru. The programme reviews were conducted by teams of 15-35 experts representing a wide range of national and external institutions. After a 2-3-month preparatory period, the conduct of the review usually lasted 2-3 weeks, including a first phase of meetings with authorities and review of documents, a second phase for field visits, and a third phase of discussion of findings and recommendations. The main lessons learned from the programme reviews were as follows: programme review is a useful tool to secure government commitment, reorient the tuberculosis control policies and replan the activities on solid grounds; the involvement of public health and academic institutions, cooperating agencies, and nongovernmental organizations secured a broad support to the new policies; programme success is linked to a centralized direction which supports a decentralized implementation through the primary health care services; monitoring and evaluation of case management functions well if it is based on the right classification of cases and quarterly reports on cohorts of patients; a comprehensive programme review should include teaching about tuberculosis in medical, nursing, and laboratory workers' schools; good quality diagnosis and treatment are the essential requirements for expanding a programme beyond the pilot testing; and control targets cannot be achieved if private and social security patients are left outside the programme scope. The methodology of comprehensive programme review should be recommended to all countries which require programme reorientation; it is also appropriate for carrying out evaluations at 4-5-year intervals in countries that are implementing the correct tuberculosis control policies.

The Sentinel-2 mission is a major part of the GMES (Global Monitoring for Environment and Security) program which has been set up by the European Union, on a joint initiative with the European Space Agency. A pair of identical satellites will observe the earth from a sun-synchronous orbit at 786 km altitude. Astrium is the prime contractor of the satellites and their payload. The MultiSpectral Instrument features a "all-SiC" TMA (Three Mirror Anastygmat) telescope. MSI will provide optical images in 13 spectral bands, in the visible and also the near infra-red range, with a 10 to 60 m resolution and a 290 km wide swath. The Boostec® SiC material is used mainly for its high specific stiffness (Youngs modulus / density) and its high thermal stability (thermal conductivity / coefficient of thermal expansion) which allow to reduce the distortions induced by thermo-elastic stresses. Its high mechanical properties as well as the relevant technology enable to make not only the mirrors but also the structure which holds them and the elements of the focal plane (including some detectors packaging). Due to the required large size, accuracy and shape complexity, developing and manufacturing some of these SiC parts required innovative manufacturing approach. It is reviewed in the present paper.

Information security: where computer science, economics and psychology meet.

PubMed

Anderson, Ross; Moore, Tyler

2009-07-13

Until ca. 2000, information security was seen as a technological discipline, based on computer science but with mathematics helping in the design of ciphers and protocols. That perspective started to change as researchers and practitioners realized the importance of economics. As distributed systems are increasingly composed of machines that belong to principals with divergent interests, incentives are becoming as important to dependability as technical design. A thriving new field of information security economics provides valuable insights not just into 'security' topics such as privacy, bugs, spam and phishing, but into more general areas of system dependability and policy. This research programme has recently started to interact with psychology. One thread is in response to phishing, the most rapidly growing form of online crime, in which fraudsters trick people into giving their credentials to bogus websites; a second is through the increasing importance of security usability; and a third comes through the psychology-and-economics tradition. The promise of this multidisciplinary research programme is a novel framework for analysing information security problems-one that is both principled and effective.

In-service Aircraft for a Global Observing System (IAGOS, http://www.iagos.org) aims at the provision of long-term, frequent, regular, accurate, and spatially resolved in situ observations of the atmospheric composition. IAGOS observation systems are deployed on a fleet of commercial aircraft. The IAGOS database is an essential part of the global atmospheric monitoring network. Data access is handled by open access policy based on the submission of research requests which are reviewed by the PIs. Users can access the data through the following web sites: http://www.iagos.fr or http://www.pole-ether.fr as the IAGOS database is part of the French atmospheric chemistry data centre ETHER (CNES and CNRS). The database is in continuous development and improvement. In the framework of the IGAS project (IAGOS for GMES/COPERNICUS Atmospheric Service), major achievements will be reached, such as metadata and format standardisation in order to interoperate with international portals and other databases, QA/QC procedures and traceability, CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) data integration within the central database, and the real-time data transmission. IGAS work package 2 aims at providing the IAGOS data to users in a standardized format including the necessary metadata and information on data processing, data quality and uncertainties. We are currently redefining and standardizing the IAGOS metadata for interoperable use within GMES/Copernicus. The metadata are compliant with the ISO 19115, INSPIRE and NetCDF-CF conventions. IAGOS data will be provided to users in NetCDF or NASA Ames format. We also are implementing interoperability between all the involved IAGOS data services, including the central IAGOS database, the former MOZAIC and CARIBIC databases, Aircraft Research DLR database and the Jülich WCS web application JOIN (Jülich OWS Interface) which combines model outputs with in situ data for intercomparison. The optimal data transfer protocol is being investigated to insure the interoperability. To facilitate satellite and model validation, tools will be made available for co-location and comparison with IAGOS. We will enhance the JOIN application in order to properly display aircraft data as vertical profiles and along individual flight tracks and to allow for graphical comparison to model results that are accessible through interoperable web services, such as the daily products from the GMES/Copernicus atmospheric service.

EMSO, a Research Infrastructure listed within ESFRI (European Strategy Forum on Research Infrastructures) Roadmap), is the European-scale network of multidisciplinary seafloor observatories from the Arctic to the Black Sea with the scientific objective of long-term real-time monitoring of processes related to geosphere/biosphere/hydrosphere interactions. EMSO will enhance our understanding of processes through long time series appropriate to the scale of the phenomena, constituting the new frontier of studying Earth interior, deep-sea biology and chemistry and ocean processes. EMSO will reply also to the need expressed in the frame of GMES (Global Monitoring for Environment and Security) to develop a marine segment integrated in the in situ and satellite global monitoring system. The EMSO development relays upon the synergy between the scientific community and the industry to improve the European competitiveness with respect to countries like USA/Canada, NEPTUNE, VENUS and MARS projects, Taiwan, MACHO project, and Japan, DONET project. In Europe the development of an underwater network is based on previous EU-funded projects since early '90, and presently supported by EU initiatives. The EMSO infrastructure will constitute the extension to the sea of the land-based networks. Examples of data recorded by seafloor observatories will be presented. EMSO is presently at the stage of Preparatory Phase (PP), funded in the EC FP7 Capacities Programme. The project has started in April 2008 and will last 4 years with the participation of 12 Institutions representing 12 countries. EMSO potential will be significantly increased also with the interaction with other Research Infrastructures addressed to Earth Science. 2.

Barber, Sarah L

2010-08-01

Caesarean section rates are increasing in Mexico and Latin America. This study evaluates the impact of a large-scale, conditional cash transfer programme in Mexico on caesarean section rates. The programme provides cash transfers to participating low income, rural households in Mexico conditional on accepting health care and nutrition supplements. The primary analyses uses retrospective reports from 979 women in poor rural communities participating in an effectiveness study and randomly assigned to incorporation into the programme in 1998 or 1999 across seven Mexican states. Using multivariate and instrumental variable analyses, we estimate the impact of the programme on caesarean sections and predict the adjusted mean rates by clinical setting. Programme participation is measured by beneficiary status, programme months and cash transfers. More than two-thirds of poor rural women delivered in a health facility. Beneficiary status is associated with a 5.1 percentage point increase in caesarean rates; this impact increases to 7.5 percentage points for beneficiaries enrolled in the programme for >or=6 months before delivery. Beneficiaries had significantly higher caesarean delivery rates in social security facilities (24.0 compared with 5.6% among non-beneficiaries) and in other government facilities (19.3 compared with 9.5%). The Oportunidades conditional cash transfer programme is associated with higher caesarean section rates in social security and government health facilities. This effect appears to be driven by the increases in disposable income from the cash transfer. These findings are relevant to other countries implementing conditional cash transfer programmes and health care requirements.

The DUNDRUM Quartet: validation of structured professional judgement instruments DUNDRUM-3 assessment of programme completion and DUNDRUM-4 assessment of recovery in forensic mental health services

PubMed Central

2011-01-01

Background Moving a forensic mental health patient from one level of therapeutic security to a lower level or to the community is influenced by more than risk assessment and risk management. We set out to construct and validate structured professional judgement instruments for consistency and transparency in decision making Methods Two instruments were developed, the seven-item DUNDRUM-3 programme completion instrument and the six item DUNDRUM-4 recovery instrument. These were assessed for all 95 forensic patients at Ireland's only forensic mental health hospital. Results The two instruments had good internal consistency (Cronbach's alpha 0.911 and 0.887). Scores distinguished those allowed no leave or accompanied leave from those with unaccompanied leave (ANOVA F = 38.1 and 50.3 respectively, p < 0.001). Scores also distinguished those in acute/high security units from those in medium or in low secure/pre-discharge units. Each individual item distinguished these levels of need significantly. The DUNDRUM-3 and DUNDRUM-4 correlated moderately with measures of dynamic risk and with the CANFOR staff rated unmet need (Spearman r = 0.5, p < 0.001). Conclusions The DUNDRUM-3 programme completion items distinguished significantly between levels of therapeutic security while the DUNDRUM-4 recovery items consistently distinguished those given unaccompanied leave outside the hospital and those in the lowest levels of therapeutic security. This data forms the basis for a prospective study of outcomes now underway. PMID:21722396

Refine instrument for auditing hospital-based child abuse and neglect violence intervention programmes prior to field-testing. A modified Delphi study to identify and rate items and domains indicative of an effective and quality child abuse and neglect intervention programme. Experts participated in four Delphi rounds: two surveys, a one-day workshop and the opportunity to comment on the penultimate instrument. New Zealand. Twenty-four experts in the field of care and protection of children. Items with panel agreement >or=85% and mean importance rating >or=4.0 (scale from 1 (not important) to 5 (very important)). There was high-level consensus on items across Rounds 1 and 2 (89% and 85%, respectively). In Round 3 an additional domain (safety and security) was agreed upon and cultural issues, alert systems for children at risk, and collaboration among primary care, community, non-government and government agencies were discussed. The final instrument included nine domains ('policies and procedures', 'safety and security', 'collaboration', 'cultural environment', 'training of providers', 'intervention services', 'documentation' 'evaluation' and 'physical environment') and 64 items. The refined instrument represents the hallmarks of an ideal child abuse and neglect programme given current knowledge and experience. The instrument enables rigorous evaluations of hospital-based child abuse and neglect intervention programmes for quality improvement and benchmarking with other programmes.

Water is the key to the well being of a community. On one hand, water security is linked to food security, as food cannot be grown without water. On the other hand, water security is linked to environmental security, as water is needed to maintain the health of a community. International cooperation is proposed for the training in Hyderabad, India, with international faculty, of ~ 300 water managers from the developing countries at an estimated cost of ~USD 3300/- per candidate (including ~ USD 1800/- for international travel), through ten interactive and customized training programmes during the period of five years, to enable them to address two crucial issues affecting the poor in the developing countries, namely, access to affordable water and coping with water scarcity. Ways of Good governance and geographical targeting of poverty alleviation programmes are built into each training programme. Each training programme will be for about three weeks (inclusive of field work). Each course will have a component common to all, plus a component customized to the biophysical and socioeconomic situation in a candidate's country. Ten course manuals will be produced. which can later be published commercially as low-cost volumes, for the benefit of the readership in the Developing countries . Each candidate will be provided his own computer, and software, and individual faculty adviser. On the basis of the training received, a candidate should be able to carry with him at the end of the course a draft outline of techno-socio-economic action plan for his country/area in respect of the theme of the course, prepared by himself/herself. A copy of this outline would be provided to the World Bank, and relevant organizations for follow- up activity

Technological development of spectral filters for Sentinel-2

2017-11-01

In the frame of the initiative for Global Monitoring for Environment and Security (GMES), jointly undertaken by the European Commission and the European Space Agency a technological development of two filter assemblies was performed for the Multi- Spectral Instrument (MSI) for Sentinel-2. The multispectral pushbroom imaging of the Earth will be performed in 10 VNIR bands (from 443 nm to 945nm) and 3 SWIR bands (from 1375 nm to 2190 nm). Possible filter coating techniques and masking concepts were considered in the frame of trade-off studies. The selected deposition concept is based on self-blocked all-dielectric multilayer band pass filter. Band pass and blocking characteristic is deposited on the space side of a single filter substrate whereas the detector side of the substrate has an antireflective coating. The space- and detector side masking design is realized by blades integrated in the mechanical parts including the mechanical interface to the filter assembly support on the MSI focal plane. The feasibility and required performance of the VNIR Filter Assembly and SWIR Filter Assembly were successfully demonstrated by breadboarding. Extensive performance tests of spectral and optical parameters and environmental tests (radiation, vibration, shock, thermal vacuum cycling, humidity) were performed on filter stripe- and filter assembly level. The presentation will contain a detailed description of the filter assembly design and the results of the performance and environmental tests.

Maximizing the use of EO products: how to leverage the potential of open geospatial service architectures

Usländer, Thomas

2012-10-01

The demand for the rapid provision of EO products with well-defined characteristics in terms of temporal, spatial, image-specific and thematic criteria is increasing. Examples are products to support near real-time damage assessment after a natural disaster event, e.g. an earthquake. However, beyond the organizational and economic questions, there are technological and systemic barriers to enable a comfortable search, order, delivery or even combination of EO products. Most portals of space agencies and EO product providers require sophisticated satellite and product knowledge and, even worse, are all different and not interoperable. This paper gives an overview about the use cases and the architectural solutions that aim at an open and flexible EO mission infrastructure with application-oriented user interfaces and well-defined service interfaces based upon open standards. It presents corresponding international initiatives such as INSPIRE (Infrastructure for Spatial Information in the European Community), GMES (Global Monitoring for Environment and Security), GEOSS (Global Earth Observation System of Systems) and HMA (Heterogeneous Missions Accessibility) and their associated infrastructure approaches. The paper presents a corresponding analysis and design methodology and two examples how such architectures are already successfully used in early warning systems for geo-hazards and toolsets for environmentallyinduced health risks. Finally, the paper concludes with an outlook how these ideas relate to the vision of the Future Internet.

Over the next few years, an increasing number of entities ranging from international, national, and regional governments, to businesses and private land-owners, are likely to become more involved in efforts to limit atmospheric concentrations of greenhouse gases. In such a world, geospatially resolved information about the location, amount, and rate of greenhouse gas (GHG) emissions will be needed, as well as the stocks and flows of all forms of carbon through terrestrial ecosystems and in the oceans. The ability to implement policies that limit GHG concentrations would be enhanced by a global, open, and transparent greenhouse gas information system (GHGIS). An operational and scientifically robust GHGIS would combine ground-based and space-based observations, carbon-cycle modeling, GHG inventories, meta-analysis, and an extensive data integration and distribution system, to provide information about sources, sinks, and fluxes of greenhouse gases at policy-relevant temporal and spatial scales. The GHGIS effort was initiated in 2008 as a grassroots inter-agency collaboration intended to rigorously identify the needs for such a system, assess the capabilities of current assets, and suggest priorities for future research and development. We will present a status of the GHGIS effort including our latest analysis and ideas for potential near-term pilot projects with potential relevance to European initiatives including the Global Monitoring for Environment and Security (GMES) and the Integrated Carbon Observing System (ICOS).

As the sun slowly sets of this first decade of the new millenium, it seems appropriate to update the sojourn of the real programmers as they adapt to their ever changing technical and business environment. Real Programmers were perfectly characterized and differentiated from their quiche-eating, Pascal programming brethren in Ed Post’s seminal “Real Programmers Don’t Use Pascal” (Datamation, 1983). My follow-up ("Real programmers do use Delphi," Software, IEEE , vol.12, no.6, pp.8, 10, 12-, Nov 1995) charted their evolution from FORTRAN-only programmers to embracing a wider range of mainstream languages and tools that still afforded ample opportunity for creativity, game-playing,more » irregular work hours, and importantly, long-term job security.« less

How much does the Supplemental Nutrition Assistance Program alleviate food insecurity? Evidence from recent programme leavers.

PubMed

Nord, Mark

2012-05-01

To estimate the effect of the US Supplemental Nutrition Assistance Program (SNAP) on the food security (consistent access to adequate food) of recipients, net of the effect of the self-selection of more food-needy households into the programme. The food security of current SNAP recipients and recent leavers is compared in cross-sectional survey data, adjusting for economic and demographic differences using multivariate logistic regression methods. A similar analysis in 2-year longitudinal panels provides additional control for selection on unobserved variables based on food security status in the previous year. Household survey data collected for the US Department of Agriculture by the US Census Bureau. Households interviewed in the Current Population Survey Food Security Supplements from 2001 to 2009. The odds of very low food security among households that continued on SNAP through the end of a survey year were 28 % lower than among those that left SNAP prior to the 30-d period during which food security was assessed. In 2-year panels with controls for the severity of food insecurity in the previous year, the difference in odds was 45 %. The results are consistent with, or somewhat higher than, the estimates from the strongest previous research designs and suggest that the ameliorative effect of SNAP on very low food security is in the range of 20-50 %.

We examined whether new structured professional judgment instruments for assessing need for therapeutic security, treatment completion and recovery in forensic settings were related to moves from higher to lower levels of therapeutic security and added anything to assessment of risk. This was a prospective naturalistic twelve month observational study of a cohort of patients in a forensic hospital placed according to their need for therapeutic security along a pathway of moves from high to progressively less secure units in preparation for discharge. Patients were assessed using the DUNDRUM-1 triage security scale, the DUNDRUM-3 programme completion scale and the DUNDRUM-4 recovery scale and assessments of risk of violence, self harm and suicide, symptom severity and global function. Patients were subsequently observed for positive moves to less secure units and negative moves to more secure units. There were 86 male patients at baseline with mean follow-up 0.9 years, 11 positive and 9 negative moves. For positive moves, logistic regression indicated that along with location at baseline, the DUNDRUM-1, HCR-20 dynamic and PANSS general symptom scores were associated with subsequent positive moves. The receiver operating characteristic was significant for the DUNDRUM-1 while ANOVA co-varying for both location at baseline and HCR-20 dynamic score was significant for DUNDRUM-1. For negative moves, logistic regression showed DUNDRUM-1 and HCR-20 dynamic scores were associated with subsequent negative moves, along with DUNDRUM-3 and PANSS negative symptoms in some models. The receiver operating characteristic was significant for the DUNDRUM-4 recovery and HCR-20 dynamic scores with DUNDRUM-1, DUNDRUM-3, PANSS general and GAF marginal. ANOVA co-varying for both location at baseline and HCR-20 dynamic scores showed only DUNDRUM-1 and PANSS negative symptoms associated with subsequent negative moves. Clinicians appear to decide moves based on combinations of current and imminent (dynamic) risk measured by HCR-20 dynamic score and historical seriousness of risk as measured by need for therapeutic security (DUNDRUM-1) in keeping with Scott's formulation of risk and seriousness. The DUNDRUM-3 programme completion and DUNDRUM-4 recovery scales have utility as dynamic measures that can off-set perceived 'dangerousness'.

Previous studies about the effectiveness of Dialectical Behaviour Therapy for the treatment of Borderline Personality Disorder have had promising results. However, no previous studies have examined its effectiveness when delivered in low secure inpatient services for women. To evaluate clinical outcomes during and after a 1-year period of admission within a low secure unit for women offering a Dialectical Behaviour Therapy programme. A naturalistic, within subjects study of clinical data collected as part of routine practice was conducted. Participants were 18 consecutively admitted women who met the diagnostic criteria for Borderline Personality Disorder and had completed at least 1 year of treatment. Measures covered: risk behaviours; self-reported symptoms of Borderline Personality Disorder, and current mood and symptom experience; staff reports of clinical problems, needs and social functioning. Scores were compared between admission and at 6 months and 1 year. There was a statistically significant improvement on all 13 measures over the year's treatment. Most improvement was demonstrated between admission and 6 months. Engagement in1-year's treatment was associated with significant reduction in risk behaviours and both staff-rated and self-rated outcome measures. Some significant questions remain about which elements of the programme are most effective but the results are encouraging.

Improving organisational resilience through enterprise security risk management.

PubMed

Petruzzi, John; Loyear, Rachelle

Enterprise Security Risk Management (ESRM) is a new philosophy and method of managing security programmes through the use of traditional risk principles. As a philosophy and life cycle, ESRM is focused on creating a business partnership between security practitioners and business leaders to more effectively provide protection against security risks in line with acceptable risk tolerances as defined by business asset owners and stakeholders. This paper explores the basics of the ESRM philosophy and life cycle and also shows how embracing the ESRM philosophy and implementing a risk-based security management model in the business organisation can lead to higher levels of organisational resilience as desired by organisation leaders, executives and the board of directors.

The security forces are a high risk group for malaria transmission in Sri Lanka. Interrupting transmission and maintaining surveillance in this group is an important component of elimination efforts. The objective of the study was to develop a prototype educational programme on malaria for security forces serving in endemic areas. An interactive seminar was designed to deliver the required knowledge. The content was on current status, transmission, signs and symptoms and the role of security personnel in identification and prevention of malaria. Each seminar was preceded by a pre-test and followed by a post test to assess the improvement of knowledge. Fifty seminars were held in eight districts over 2 months with 2301 security forces personnel participating. Pre seminar knowledge on malaria was significantly better in the medical corps, those who had completed secondary education and in the Army compared to other security forces (p<0.001). Participation in the seminar resulted in an improvement in all domains tested as shown by test scores in post seminar assessment (p<0.001). Conducting a formal educational programme is an effective strategy to improve awareness on malaria amongst security forces personnel who are a high risk group for re-introduction of malaria into the country. © The Author 2014.

Determining the reasons people choose to study nursing may help educators and managers develop student-focussed and enticing nursing programmes. In Australia, little research has been undertaken with students entering nursing programmes and the reasons for their choice. The aim of this study was to determine why new students choose to enter nursing at university. A descriptive survey design. An urban university in Sydney, Australia. Undergraduate nursing students at the beginning of their first year of study. An open-ended question relating to the reasons for students' choice of a nursing programme was included in the survey. The transcribed textual data were content analysed for words related to the students' choice. The students' reasons for entering nursing programmes were both personal and career related, with personal being more dominant. The reasons to start nursing were: being able to help and care for people, job security, the ability to enter tertiary education and the enjoyment or love of nursing. Nursing remains a career of choice for young and mature students entering university. It is seen to provide security, interest and opportunity to help and care for others. Universities must focus on this as they develop programmes for a generation where multiple changes of career appear inevitable during their lifetime. The nursing profession needs to look at career pathways after graduation that provide these challenges within nursing itself.

Through the Global Partnership the UK continues to make a significant contribution to improve national and global security. Over the past year the UK has continued to implement a wide range of projects across the breadth of its Global Partnership Programme. As well as ensuring the Programme is robust and capable of dealing with new challenges, the UK has cooperated with other donor countries to help them progress projects associated with submarine dismantling, scientist redirection, enhancing nuclear security and Chemical Weapons Destruction. The Global Partnership, although only five years old, has already achieved a great deal. Some 23 states, plusmore » the European Union, are now working closer together under the Global Partnership, and collectively have enhanced global regional and national security by reducing the availability of Weapons of Mass Destruction (WMD) materials and expertise to both states of concern and terrorists. Considerable progress has already been made in, for example: - Improving the security of fissile materials, dangerous biological agents and chemical weapons stocks; - Reducing the number of sites containing radioactive materials; - Working towards closure of reactors still producing weapon-grade plutonium; - Improving nuclear safety to reduce the risks of further, Chernobyl style accidents; - Constructing facilities for destroying Chemical Weapons stocks, and starting actual destruction; - Providing sustainable employment for former WMD scientists to reduce the risk that their expertise will be misused by states or terrorists. By contributing to many of these activities, the UK has helped to make the world safer. This paper reports on the UK's practical and sustainable contribution to the Global Partnership and identifies a number of challenges that remain if it is to have a wider impact on reducing the threats from WMD material.

Young, Helen

2007-03-01

The humanitarian crisis in Darfur remains extremely serious. The optimism that followed the signing of the Abuja Peace Accord was followed by a rapid deterioration in security on the ground in part associated with increasing factionalism in various rebel movements. This paper briefly reviews the evolution of the crisis, its impact on lives and livelihoods and the response by the World Food Programme (WFP) to June 2006. The major challenges and issues facing the food aid programme in the previous 18 months included: dealing with insecurity while maintaining or even extending programme outreach; the need to link protection with assistance more explicitly; and determining the wider impact of food aid programming on the processes and institutions linked with the conflict. The paper discusses the main strategic issues facing WFP in the future such as: integrating security and protection with needs assessments and operational decisions, broadening response strategies beyond food aid and bringing livelihoods to the fore, the need to review cost-efficiency, promoting partnerships and strengthening national and regional capacities.

Effects of a free school breakfast programme on school attendance, achievement, psychosocial function, and nutrition: a stepped wedge cluster randomised trial

PubMed Central

2010-01-01

Background Approximately 55,000 children in New Zealand do not eat breakfast on any given day. Regular breakfast skipping has been associated with poor diets, higher body mass index, and adverse effects on children's behaviour and academic performance. Research suggests that regular breakfast consumption can improve academic performance, nutrition and behaviour. This paper describes the protocol for a stepped wedge cluster randomised trial of a free school breakfast programme. The aim of the trial is to determine the effects of the breakfast intervention on school attendance, achievement, psychosocial function, dietary habits and food security. Methods/Design Sixteen primary schools in the North Island of New Zealand will be randomised in a sequential stepped wedge design to a free before-school breakfast programme consisting of non-sugar coated breakfast cereal, milk products, and/or toast and spreads. Four hundred children aged 5-13 years (approximately 25 per school) will be recruited. Data collection will be undertaken once each school term over the 2010 school year (February to December). The primary trial outcome is school attendance, defined as the proportion of students achieving an attendance rate of 95% or higher. Secondary outcomes are academic achievement (literacy, numeracy, self-reported grades), sense of belonging at school, psychosocial function, dietary habits, and food security. A concurrent process evaluation seeks information on parents', schools' and providers' perspectives of the breakfast programme. Discussion This randomised controlled trial will provide robust evidence of the effects of a school breakfast programme on students' attendance, achievement and nutrition. Furthermore the study provides an excellent example of the feasibility and value of the stepped wedge trial design in evaluating pragmatic public health intervention programmes.

Plant breeding can be made more efficient by having fewer, better crosses.

Crop yields have to increase to provide food security for the world's growing population. To achieve these yield increases there will have to be a significant contribution from genetic gains made by conventional plant breeding. However, the breeding process is not efficient because crosses made between parental combinations that fail to produce useful varieties consume over 99% of the resources. We tested in a rice-breeding programme if its efficiency could be improved by using many fewer, but more judiciously chosen crosses than usual. In a 15-year programme in Nepal, with varietal testing also in India and Bangladesh, we made only six crosses that were stringently chosen on complementary parental performance. We evaluated their success by the adoption and official release of the varieties they produced. We then modelled optimum cross number using assumptions based on our experimental results.Four of the six crosses succeeded. This was a fifty-fold improvement over breeding programmes that employ many crosses where only about one, or fewer, crosses in 200 succeed. Based on these results, we modelled the optimum number of crosses by assuming there would be a decline in the reliability of the breeder's prediction of the value of each cross as more crosses were made (because there is progressively less information on the traits of the parents). Fewer-cross programmes were more likely to succeed and did so using fewer resources. Making more crosses reduced the overall probability of success of the breeding programme. The efficiency of national and international breeding programmes would be increased by making fewer crosses among more carefully chosen parents. This would increase the number of higher yielding varieties that are delivered to farmers and hence help to improve food security.

SSALTO/DUACS: Faster data delivery for operational oceanography and GMES

NASA Astrophysics Data System (ADS)

Dorandeu, J.; Dibarboure, G.; Larnicol, G.; Picot, N.

2008-12-01

This paper describes the DUACS multi-mission system, and its most relevant improvements and changes. Initiated 10 years ago with an EC project, DUACS is now a part of the CNES multi-mission ground segment SSALTO, and the backbone of the Sea Level Thematic Assembly Centre (SL-TAC) of the GMES Marine Core Service. Near Real Time (NRT): Daily Operational Products DUACS-NRT provides GODAE, climate forecasting centres, the MyOcean EU FP7 project, and real time oceanographic research (e.g.: in-situ campaigns) with directly useable, high quality near real time altimeter data. Regional products (European Shelves, Mediterranean Sea, and Black Sea) are delivered to operational projects. Commercial applications are also developed for the fishery and offshore drilling industries. All DUACS near real time products are generated and distributed on a daily basis to reduce the NRT delay, and to smooth the operational procedures of NRT users. DUACS features a systematic quality control of the input data, the system itself, and its products with detailed reports put online twice per week. The system also carries out on-the-fly editing and reprocessing of erroneous datasets, as well as a long term monitoring of NRT data it has used, to quickly detect anomalies, drifts and discontinuities in incoming altimeter data. Delayed Time (DT): A consistent data set from built upon all altimeters The second generation of DUACS-DT products is composed of global data sets of along track and gridded Sea Level Anomaly, Absolute Dynamic Topography, and geostrophic currents, but also of regional-specific products (higher resolution, optimized parameters). DUACS reprocessed all past altimeter data: Jason-1, T/P, ENVISAT, GFO, ERS1/2 and GEOSAT. These delayed time products are regularly updated when new Level2 data are released and fully validated. The system operationally integrates the state-of-the-art corrections, models and references recommended by the altimeter community, as well as the best Cal/Val and cross-calibration and merging algorithms. Ongoing Improvements to secure multi-mission products Adding Jason-2 to the system is arguably the most important improvement on DUACS in 2008. Additionally, the effort to improve the quality of DUACS combined data and the robustness of the NRT system are ongoing with the release of Key Performance Indicators on the system, and Ocean Indicators for a near real time ocean monitoring. Last year, preliminary studies were carried out to merge into the high-accuracy NRT system, innovative information of lower quality altimeter data flows such as OSDR / FDGDR / OGDR (real time data delivered in a few hours as opposed to 2 or 3 days for classical NRT data), as well as CryoSat data. These offline studies and experimental NRT productions will be integrated to the system in order to guarantee sustainability and quality in the operational DUACS framework.

Pacific Northwest National Laboratory’s (PNNL) nuclear cyber security team has been providing technical support to the U.S. Nuclear Regulatory Commission (NRC) since 2002. This team has provided cyber security technical experties in conducting cyber security inspections, developing of regulatory rules and guidance, reviewing facility cyber security plans, developing inspection guidance, and developing and teaching NRC inspectors how to conduct cyber security assessments. The extensive experience the PNNL team has gathered has allowed them to compile a lenghty list of recommendations on how to improve cyber security programs and conduct assessments. A selected set of recommendations are presented, including the needmore » to: integrate an array of defenisve strategies into a facility’s cyber security program, coordinate physical and cyber security activities, train phycial security forces to resist a cyber-enabled physical attack, improve estimates of the consequences of a cyber attack, properly resource cyber security assessments, appropropriately account for insider threats, routinely monitor security devices for potential attacks, supplement compliance-based requirements with risk-based decision making, and introduce the concept of resilience into cyber security programs.« less

The total annual demand for wood in Upper Volta is about 4.2 million cubic m solid wood, 94% of the population depends on wood for energy (compared with 84% in the Sahel states as a whole), and more than 30% of income in urban areas is spent on acquiring wood. Any policy aimed at securing adequate food supplies for the population must therefore be accompanied by a programme for safeguarding energy supplies. Measures which should be included in an integrated energy programme are presented and details are given of Upper Volta's forestry programme. 21 references.

[The role of health education in preventive medicine strategy of the Mexican Institute of Social Security].

PubMed

Rodríguez Véliz, A M

1982-01-01

This article presents the Mexican Institute for Social Security (IMSS) created in 1943 and describes its main features, its programmes and the role played by health education inside the programmes. It ends by explaining the present situation concerning health education and the changes which are presently envisaged. During its first twenty years, the IMSS promoted preventive medicine and trained health personnel. Since 1979 it has concerned itself mainly with some 10 million peasants and marginal groups. In the frame of a national development programme, a vaccination and detection campaign were implemented and the distribution system of potable water was extended. Mexico with a population of 73 million has the dual characteristics of a developed and a developing country (70 per cent of its population is urban, 30 per cent rural). The overcrowded cities contrast with the isolated rural areas where sanitary conditions are poor and life difficult. The main causes of mortality, in 1978, were: -in the towns: car accidents, cardiovascular diseases and suicide; -in rural areas, acute respiratory infections and intestinal infections. The 1978 Alma Ata international conference on primary health care and the meeting of Ministers of health convened in 1980 by the Pan American Health Organization endorsed the IMSS programmes which emphasize prevention, promote health education and community participation. The cost of preventive measures being cheaper than treatment, 203 million pesos were saved and allocated to the expansion of programmes. Systematic immunization has resulted in a sharp decline of diphteria, polio, rabies, typhoid, pertussis and measles. Early detection of tumours of cervix uteri has saved many lives.

Evaluation of the ability of the MACC-II Reanalysis to reproduce the distribution of O3 and CO in the UTLS as measured by MOZAIC-IAGOS

Tropospheric ozone is probably one of the most important trace gases in the atmosphere. It plays a major role in the chemistry of the troposphere by exerting a strong influence on the concentrations of oxidants such as hydroxyl radical (OH) and is the third greenhouse gas after carbon dioxide and methane. Its radiative impact is of particular importance in the Upper Troposphere / Lower Stratosphere (UTLS), the most critical region regarding the climate change. Carbon Monoxide (CO) is one of the major ozone precursors (originating from all types of combustion) in the troposphere. In the UTLS, it also has implications for stratospheric chemistry and indirect radiative forcing effects (as a chemical precursor of CO2 and O3). Assessing the global distribution (and possibly trends) of O3 and CO in this region of the atmosphere, combining high resolution in situ data and the most appropriate global 3D model to further quantify the different sources and their origins is then of particular interest. This is one of the objectives of the MOZAIC-IAGOS (http://www.iagos.fr) and MACC-II (http://www.gmes-atmosphere.eu) European programs. The aircraft of the MOZAIC program have collected simultaneously O3 and CO data regularly all over the world since the end of 2001. Most of the data are recorded in northern mid-latitudes, in the UTLS region (as commercial aircraft cruise altitude is between 9 and 12 km). MACC-II aims at providing information services covering air quality, climate forcing and stratospheric ozone, UV radiation and solar-energy resources, using near real time analysis and forecasting products, and reanalysis. The validation reports of the MACC models are regularly published (http://www.gmes-atmosphere.eu/services/gac/nrt/ and http://www.gmes-atmosphere.eu/services/gac/reanalysis/). We will present and discuss the performance of the MACC-reanalysis, including the ECMWF-Integrated Forecasting System (IFS) coupled to the CTM MOZART with 4DVAR data assimilation, to reproduce ozone and CO in the UTLS, as evaluated by the observations of MOZAIC between 2003 and 2008. In the UT, the model tends to overestimate O3 by about 30-40 % in the mid-latitudes and polar regions. This applies broadly to all seasons but is more marked in DJF and MAM. In tropical regions, the model underestimates UT ozone by about 20 % in all seasons but this is stronger in JJA. Upper-tropospheric CO is globally underestimated by the model in all seasons, by 10-20 %. In the southern hemisphere, it is particularly the case in SON in the regions of wildfires in South Africa. In the northern hemisphere, the zonal gradient of CO between the US, Europe and Asia is not well-captured by the model, especially in MAM.

The Traceable Radiometry Underpinning Terrestrial- and Helio- Studies (TRUTHS) mission offers a novel approach to the provision of key scientific data with unprecedented radiometric accuracy for Earth Observation (EO) and solar studies, which will also establish well-calibrated reference targets/standards to support other EO missions. This paper will present the TRUTHS mission and its objectives. TRUTHS will be the first satellite mission to calibrate its instrumentation directly to SI in orbit, overcoming the usual uncertainties associated with drifts of sensor gain and spectral shape by using an electrical rather than an optical standard as the basis of its calibration. The range of instruments flown as part of the payload will also provide accurate input data to improve atmospheric radiative transfer codes by anchoring boundary conditions, through simultaneous measurements of aerosols, particulates and radiances at various heights. Therefore, TRUTHS will significantly improve the performance and accuracy of Earth observation missions with broad global or operational aims, as well as more dedicated missions. The provision of reference standards will also improve synergy between missions by reducing errors due to different calibration biases and offer cost reductions for future missions by reducing the demands for on-board calibration systems. Such improvements are important for the future success of strategies such as Global Monitoring for Environment and Security (GMES) and the implementation and monitoring of international treaties such as the Kyoto Protocol. TRUTHS will achieve these aims by measuring the geophysical variables of solar and lunar irradiance, together with both polarised and un-polarised spectral radiance of the Moon, and the Earth and its atmosphere.

Lowering Entry Barriers for Multidisciplinary Cyber(e)-Infrastructures

NASA Astrophysics Data System (ADS)

Nativi, S.

2012-04-01

Multidisciplinarity is more and more important to study the Earth System and address Global Changes. To achieve that, multidisciplinary cyber(e)-infrastructures are an important instrument. In the last years, several European, US and international initiatives have been started to carry out multidisciplinary infrastructures, including: the Spatial Information in the European Community (INSPIRE), the Global Monitoring for Environment and Security (GMES), the Data Observation Network for Earth (DataOne), and the Global Earth Observation System of Systems (GEOSS). The majority of these initiatives are developing service-based digital infrastructures asking scientific Communities (i.e. disciplinary Users and data Producers) to implement a set of standards for information interoperability. For scientific Communities, this has represented an entry barrier which has proved to be high, in several cases. In fact, both data Producers and Users do not seem to be willing to invest precious resources to become expert on interoperability solutions -on the contrary, they are focused on developing disciplinary and thematic capacities. Therefore, an important research topic is lowering entry barriers for joining multidisciplinary cyber(e)-Infrastructures. This presentation will introduce a new approach to achieve multidisciplinary interoperability underpinning multidisciplinary infrastructures and lowering the present entry barriers for both Users and data Producers. This is called the Brokering approach: it extends the service-based paradigm by introducing a new a Brokering layer or cloud which is in charge of managing all the interoperability complexity (e.g. data discovery, access, and use) thus easing Users' and Producers' burden. This approach was successfully experimented in the framework of several European FP7 Projects and in GEOSS.

Utilizing Free and Open Source Software to access, view and compare in situ observations, EO products and model output data

The GreenSeas project (Development of global plankton data base and model system for eco-climate early warning) aims to advance the knowledge and predictive capacities of how marine ecosystems will respond to global change. A main task has been to set up a data delivery and monitoring core service following the open and free data access policy implemented in the Global Monitoring for the Environment and Security (GMES) programme. The aim is to ensure open and free access to historical plankton data, new data (EO products and in situ measurements), model data (including estimates of simulation error) and biological, environmental and climatic indicators to a range of stakeholders, such as scientists, policy makers and environmental managers. To this end, we have developed a geo-spatial database of both historical and new in situ physical, biological and chemical parameters for the Southern Ocean, Atlantic, Nordic Seas and the Arctic, and organized related satellite-derived quantities and model forecasts in a joint geo-spatial repository. For easy access to these data, we have implemented a web-based GIS (Geographical Information Systems) where observed, derived and forcasted parameters can be searched, displayed, compared and exported. Model forecasts can also be uploaded dynamically to the system, to allow modelers to quickly compare their results with available in situ and satellite observations. We have implemented the web-based GIS(Geographical Information Systems) system based on free and open source technologies: Thredds Data Server, ncWMS, GeoServer, OpenLayers, PostGIS, Liferay, Apache Tomcat, PRTree, NetCDF-Java, json-simple, Geotoolkit, Highcharts, GeoExt, MapFish, FileSaver, jQuery, jstree and qUnit. We also wanted to used open standards to communicate between the different services and we use WMS, WFS, netCDF, GML, OPeNDAP, JSON, and SLD. The main advantage we got from using FOSS was that we did not have to invent the wheel all over again, but could use already existing code and functionalities on our software for free: Of course most the software did not have to be open source for this, but in some cases we had to do minor modifications to make the different technologies work together. We could extract the parts of the code that we needed for a specific task. One example of this was to use part of the code from ncWMS and Thredds to help our main application to both read netCDF files and present them in the browser. This presentation will focus on both difficulties we had with and advantages we got from developing this tool with FOSS.

[National health resources for highly specialised medicine].

PubMed

Bratlid, Dag; Rasmussen, Knut

2005-11-03

In order to monitor quality and efficiency in the use of health resources for highly specialised medicine, a National Professional Council has since 1990 advised the Norwegian health authorities on the establishing and localisation of such services. A comprehensive review of both the quality, economy and the geographical distribution of patients in each specialised service has been carried out. 33 defined national programmes were centralised to one hospital only and distributed among seven university hospitals. Eight multiregional programmes were centralised to two hospitals only and included four university hospitals. In 2001, a total of 2711 new patients were treated in these programmes. The system seems to have secured a sufficient patient flow to each programme so as to maintain quality. However, a geographically skewed distribution of patients was noted, particularly in some of the national programmes. In a small country like Norway, with 4.5 million inhabitants, a centralised monitoring of highly specialised medicine seems both rational and successful. By the same logic, however, international cooperation should probably be sought for the smallest patient groups.

Security in Full-Force

NASA Technical Reports Server (NTRS)

2002-01-01

When fully developed for NASA, Vanguard Enforcer(TM) software-which emulates the activities of highly technical security system programmers, auditors, and administrators-was among the first intrusion detection programs to restrict human errors from affecting security, and to ensure the integrity of a computer's operating systems, as well as the protection of mission critical resources. Vanguard Enforcer was delivered in 1991 to Johnson Space Center and has been protecting systems and critical data there ever since. In August of 1999, NASA granted Vanguard exclusive rights to commercialize the Enforcer system for the private sector. In return, Vanguard continues to supply NASA with ongoing research, development, and support of Enforcer. The Vanguard Enforcer 4.2 is one of several surveillance technologies that make up the Vanguard Security Solutions line of products. Using a mainframe environment, Enforcer 4.2 achieves previously unattainable levels of automated security management.

Evolutionary Aspects for Technology Policy: the Case of Galileo Public-Private Partnership

NASA Astrophysics Data System (ADS)

Zervos, Vasilis

2002-01-01

This paper examines the impact of strategic interactions on Private-Public Partnerships (PPPs) in space. Though there is substantial business and economics literature on PPPs, it is traditionally focused on the relationships within the partnerships (low level) and the respective factors affecting its success. The contribution of this paper is that it examines the political economy of PPPs, analysing how `high-level' strategic interactions across public-private sectors in Europe and the US determine their behaviour and success. Within this context, the European case of Galileo and other national space projects, such as the US plans for a space-based anti- missile defence, are each based on different types of PPPs, confined within the geographical borders of the two areas. The security and commercial benefits of such programmes for the respective space industries and economies have a direct impact on the other area's industry and sense of security. The paper shows that trans- Atlantic cooperation at public policy level is essential to allow the respective industries to explore the benefits of cross-border strategic research partnerships (SRPs). This will reduce the costs of the respective programmes, addressing security concerns.

The Antibiotics Smart Use (ASU) programme was introduced in Thailand as a model to promote the rational use of medicines, starting with antibiotics. The programme's first phase consisted of assessing interventions intended to change prescribing practices; the second phase examined the feasibility of programme scale-up. Currently the programme is in its third phase, which centres on sustainability. This paper describes the concept behind ASU, the programme's functional modalities, the development of its conceptual framework and the implementation of its first and second phases. To change antibiotic prescription practices, multifaceted interventions at the individual and organizational levels were implemented; to maintain behaviour change and scale up the programme, interventions at the network and policy levels were used. The National Health Security Office has adopted ASU as a pay-for-performance criterion, a major achievement that has led to the programme's expansion nationwide. Despite limited resources, programme scale-up and sustainability have been facilitated by the promotion of local ownership and mutual recognition, which have generated pride and commitment. ASU is clearly a workable entry point for efforts to rationalize the use of medicines in Thailand. Its long-term sustainability will require continued local commitment and political support, effective auditing and integration of ASU into routine systems with appropriate financial incentives.

The climate sensitivity of food security in Mali - a historical perspective on availability and access dimensions

We present results based on an analysis of a 2005 livelihood survey of ~2000 rural households in ~200 villages scattered across Mali, a sparsely populated, large land-locked country in West Africa, to elucidate the role of climate variability and change in shaping availability and access dimensions of food security. The Comprehensive Food Security Vulnerability Analysis is a recurrent survey carried out by the World Food Programme and in-country partners to map out nutritional and socio-economic status during normal (~food secure) conditions in the hope of understanding underlying cause(s) and prevent the next food security crisis. We set the spatial characterization of food security that emerges from the CFSVA against the background of a varying climate, on intra-seasonal, interannual and multi-decadal time scales: through elucidation of the influence of climate on agricultural production we arrive at an interpretation of structural and conjunctural events affecting food security. We conclude with a discussion of possible interventions to reduce vulnerability.

The inadequacy of inpatient facilities for women with severe psychiatric and co-morbid difficulties has been repeatedly documented. The establishment of effective therapeutic programmes for women in medium psychiatric facilities is also in their infancy, and little research has been undertaken. This article describes the development of a 'best practice' psychological treatment programme for women with a dual diagnosis. Emphasis is placed on the need to develop further intensive gender-specific services using an established model for effective therapeutic service development. In addition to a detailed description of the group therapy programme, staff training initiatives, methods for ensuring treatment integrity and a methodology for service evaluation is given.

Enhanced recovery clinical education programme improves quality of post-operative care.

PubMed

McDonald, Ruth

2015-01-01

Quality is the driving principle of Enhanced Recovery (ER). It improves the patient experience by getting patients better sooner and changes clinical practice to make care safer and more efficient. As a consequence of ER patients spend less time in hospital. A successful ER programme began to fail after organisational restructuring and staff changes. Patients did not meet their ER goals and length of stay (LOS) increased. An ER nurse was appointed to get the programme back on track. This involved a multidisciplinary approach to an ER clinical education programme. The programme aimed to develop knowledge of the physiology of post-operative recovery and the evidence underpinning the interventions required. This was considered crucial to secure longer term staff engagement while avoiding unthinking protocol driven compliance. Success of the education programme was measured by improved outcomes in patient LOS and readmission statistics. During the four months of the clinical education programme there were no significant changes in monthly LOS. At six months post implementation of the programme there was a reduction in LOS of 0.6 days compared to the previous six months. At 12 months there was a reduction in 1.1 days compared with previous 12 months. There was a mean reduction of 28 day readmissions for all elective gynaecology surgery of 1.1 patients per month in the 12 months post programme implementation compared to the 12 months before. Delivering a multidisciplinary participatory education programme improved overall understanding of ER, and achieved sustained improvement in ER for patient benefit.

The incoming Sentinel missions have been designed to be the first remote sensing satellite system devoted to operational services. In particular, the Synthetic Aperture Radar (SAR) Sentinel-1 sensor, dedicated to globally acquire over land in the interferometric mode, guarantees an unprecedented capability to investigate and monitor the Earth surface deformations related to natural and man-made hazards. Thanks to the global coverage strategy and 12-day revisit time, jointly with the free and open access data policy, such a system will allow an extensive application of Differential Interferometric SAR (DInSAR) techniques. In such a framework, European Commission has been funding several projects through the GMES and Copernicus programs, aimed at preparing the user community to the operational and extensive use of Sentinel-1 products for risk mitigation and management purposes. Among them, the FP7-DORIS, an advanced GMES downstream service coordinated by Italian National Council of Research (CNR), is based on the fully exploitation of advanced DInSAR products in landslides and subsidence contexts. In particular, the DORIS project (www.doris-project.eu) has developed innovative scientific techniques and methodologies to support Civil Protection Authorities (CPA) during the pre-event, event, and post-event phases of the risk management cycle. Nonetheless, the huge data stream expected from the Sentinel-1 satellite may jeopardize the effective use of such data in emergency response and security scenarios. This potential bottleneck can be properly overcome through the development of modern infrastructures, able to efficiently provide computing resources as well as advanced services for big data management, processing and dissemination. In this framework, CNR and ESA have tightened up a cooperation to foster the use of GRID and cloud computing platforms for remote sensing data processing, and to make available to a large audience advanced and innovative tools for DInSAR products generation and exploitation. In particular, CNR is porting the multi-temporal DInSAR technique referred to as Small Baseline Subset (SBAS) into the ESA G-POD (Grid Processing On Demand) and CIOP (Cloud Computing Operational Pilot) platforms (Elefante et al., 2013) within the SuperSites Exploitation Platform (SSEP) project, which aim is contributing to the development of an ecosystem for big geo-data processing and dissemination. This work focuses on presenting the main results that have been achieved by the DORIS project concerning the use of advanced DInSAR products for supporting CPA during the risk management cycle. Furthermore, based on the DORIS experience, a sustainability model for Core and Downstream Copernicus services based on the effective exploitation of cloud platforms is proposed. In this framework, remote sensing community, both service providers and users, can significantly benefit from the Helix Nebula-The Science Cloud initiative, created by European scientific institutions, agencies, SMEs and enterprises to pave the way for the development and exploitation of a cloud computing infrastructure for science.

Dynamic Construction Scheme for Virtualization Security Service in Software-Defined Networks

PubMed Central

Lin, Zhaowen; Tao, Dan; Wang, Zhenji

2017-01-01

For a Software Defined Network (SDN), security is an important factor affecting its large-scale deployment. The existing security solutions for SDN mainly focus on the controller itself, which has to handle all the security protection tasks by using the programmability of the network. This will undoubtedly involve a heavy burden for the controller. More devastatingly, once the controller itself is attacked, the entire network will be paralyzed. Motivated by this, this paper proposes a novel security protection architecture for SDN. We design a security service orchestration center in the control plane of SDN, and this center physically decouples from the SDN controller and constructs SDN security services. We adopt virtualization technology to construct a security meta-function library, and propose a dynamic security service composition construction algorithm based on web service composition technology. The rule-combining method is used to combine security meta-functions to construct security services which meet the requirements of users. Moreover, the RETE algorithm is introduced to improve the efficiency of the rule-combining method. We evaluate our solutions in a realistic scenario based on OpenStack. Substantial experimental results demonstrate the effectiveness of our solutions that contribute to achieve the effective security protection with a small burden of the SDN controller. PMID:28430155

Governance and Purchasing Function under Social Health Insurance in Nepal: Looking Back and Moving Forward.

PubMed

Sapkota, V P; Bhusal, U P

2017-01-01

Nepal is pursuing Social Health Insurance as a way of mobilizing revenues to achieve Universal Health Coverage. The Social Health Insurance governance encourages service providers to maintain quality and efficiency in services provision by practicing strategic purchasing. Social Health Security Programme is a social protection program which aspires to achieve the goals of Social Health Insurance. Social Health Security Development Committee needs to consider following experiences to function as a strategic purchaser. The Social Health Security Development Committee need to be an independent body instead of falling under Ministry of Health. Similarly, purchasing of health services needs to be made strategic, i.e., Social Health Security Development Committee should use its financial power to guide the provider behavior that will eventually contribute to achieving the goals of quality and efficiency in service provision. The other social health security funds should be merged with Social Health Security Development Committee and develop a single national fund. Finally, the state has to regulate and monitor the performance of the SHI agency.

Microcredit participation and child health: results from a cross-sectional study in Peru.

PubMed

Moseson, H; Hamad, R; Fernald, L

2014-12-01

Childhood malnutrition is a major consequence of poverty worldwide. Microcredit programmes-which offer small loans, financial literacy and social support to low-income individuals-are increasingly promoted as a way to improve the health of clients and their families. This study evaluates the hypothesis that longer participation in a microcredit programme is associated with improvements in the health of children of microcredit clients. Cross-sectional data were collected in February 2007 from 511 clients of a microcredit organisation in Peru and 596 of their children under 5 years of age. The primary predictor variable was length of participation in the microcredit programme. Outcome variables included height, weight, anaemia, household food security and parent-reported indicators of child health. Multivariate linear and logistic regressions assessed the association between the number of loan cycles and child health outcomes. Pathways through which microcredit may have influenced health outcomes were also explored via mediation analyses. Longer participation in microcredit was associated with greater household food security and reduced likelihood of childhood anaemia. No significant associations were observed between microcredit participation and incidence of childhood illnesses or anthropometric indicators. Increased consumption of red meat may mediate the association between the number of loan cycles and food security, but not the association with anaemia. The effects of microcredit on the health of clients' children are understudied. Exploratory findings from this analysis suggest that microcredit may positively influence child health, and that diet may play a causal role. Published by the BMJ Publishing Group Limited.

Many countries have weak disease surveillance and immunization systems. The elimination of polio creates an opportunity to use staff and assets from the polio eradication programme to control other vaccine-preventable diseases and improve disease surveillance and immunization systems. In 2003, the active surveillance system of Nepal's polio eradication programme began to report on measles and neonatal tetanus cases. Japanese encephalitis and rubella cases were added to the surveillance system in 2004. Staff from the programme aided the development and implementation of government immunization policies, helped launch vaccination campaigns, and trained government staff in reporting practices and vaccine management. Nepal eliminated indigenous polio in 2000, and controlled outbreaks caused by polio importations between 2005 and 2010. In 2014, the surveillance activities had expanded to 299 sites, with active surveillance for measles, rubella and neonatal tetanus, including weekly visits from 15 surveillance medical officers. Sentinel surveillance for Japanese encephalitis consisted of 132 sites. Since 2002, staff from the eradication programme have helped to introduce six new vaccines and helped to secure funding from Gavi, the Vaccine Alliance. Staff have also assisted in responding to other health events in the country. By expanding the activities of its polio eradication programme, Nepal has improved its surveillance and immunization systems and increased vaccination coverage of other vaccine-preventable diseases. Continued donor support, a close collaboration with the Expanded Programme on Immunization, and the retention of the polio eradication programme's skilled workforce were important for this expansion.

The science of human security: a response from political science.

PubMed

Roberts, David

2008-01-01

The concept of human security has developed in significance in the last decade to the point that its meaning and validity is hotly contested in the field of international relations, security, and development studies. A key consideration relates to its ambiguity at best and its amorphousness at worst. Medical scholarship proposes approaches that may render more meaningful the concept. However, collaboration and co-operation between political scientists and medical practitioners offers even greater potential to this vital programme. The latter offer the technical and methodological skills and approaches lacking in political science, whilst the former develop political frameworks to shift the causal focus towards human, institutional and structural agency in mass avoidable global civilian mortality.

Factors of importance to maintaining regular dental care after a behavioural intervention for adults with dental fear: a qualitative study.

Dental phobia is prevalent in the general population and can be successfully treated through cognitive behavioural therapy, which results in patients being able to cope with dental treatments. The aim of this study was to increase the understanding of factors of importance for maintaining regular dental care after completion of a cognitive behavioural therapy programme. A qualitative study design was used. Fourteen individuals who had successfully completed the programme and had thereafter been referred to a general dental practitioner were interviewed. An interview guide with open-ended questions was used. The interviews were tape-recorded and transcribed verbatim. The texts were analysed using descriptive and qualitative content analysis (Grounded Theory). The manifest analysis identified four content areas: experience of dental care, content of the behavioural therapy programme, perception of therapy and impact on quality of life. The latent analysis identified influence on quality of life, security, activity and barriers to dental care as categories. Although all informants had successfully completed the dental fear treatment programme, only a few stated that they had an uncomplicated relation to dental care afterwards. Barriers to dental care were lack of money and fear. A sense of security was conclusive to coping with dental care, and a respectful approach on the part of the dental care personnel was essential to development of this sense. Confidence in one's own ability to cope with dental care and the right to guide the treatment were important. Thus the theme in the present study was self-efficacy and respectful dental care personnel.

Seasonal monitoring of soil erosion at regional scale: An application of the G2 model in Crete focusing on agricultural land uses

2014-04-01

A new soil erosion model, namely G2, was applied in the island of Crete with a focus on agricultural land uses, including potential grazing lands. The G2 model was developed within the Geoland2 project as an agro-environmental service in the framework of the Global Monitoring for Environment and Security (GMES, now Copernicus) initiative. The G2 model takes advantage of the empirical background of the Universal Soil Loss Equation (USLE) and the Gavrilovic model, together with readily available time series of vegetation layers and 10-min rainfall intensity data to produce monthly time-step erosion risk maps at 300 m cell size. The innovations of the G2 model include the implementation of land-use influence parameters based on empirical data and the introduction of a corrective term in the estimation of the topographic influence factor. The mean annual erosion rate in Crete was found to be 8.123 t ha-1. The season from October to January (the rainy season in Crete) was found to be the most critical, accounting for 80% of the annual erosion in the island. Seasonal erosion figures proved to be crucial for the identification of erosion hotspots and of risky land uses. In Crete, high annual erosion figures were detected in natural grasslands and shrublands (14.023 t ha-1), mainly due to the intensification of livestock grazing during the past decades. The G2 model allows for the integrated spatio-temporal monitoring of soil erosion per land-use type based on moderate data input requirements and existing datasets.

Sentinel-2 diffuser on-ground calibration

The Sentinel-2 multi-spectral instrument (MSI) will provide Earth imagery in the frame of the Global Monitoring for Environment and Security (GMES) initiative which is a joint undertaking of the European Commission and the Agency. MSI instrument, under Astrium SAS responsibility, is a push-broom spectro imager in 13 spectral channels in VNIR and SWIR. The instrument radiometric calibration is based on in-flight calibration with sunlight through a quasi Lambertian diffuser. The diffuser covers the full pupil and the full field of view of the instrument. The on-ground calibration of the diffuser BRDF is mandatory to fulfil the in-flight performances. The diffuser is a 779 x 278 mm2 rectangular flat area in Zenith-A material. It is mounted on a motorised door in front of the instrument optical system entrance. The diffuser manufacturing and calibration is under the Centre Spatial of Liege (CSL) responsibility. The CSL has designed and built a completely remote controlled BRDF test bench able to handle large diffusers in their mount. As the diffuser is calibrated directly in its mount with respect to a reference cube, the error budget is significantly improved. The BRDF calibration is performed directly in MSI instrument spectral bands by using dedicated band-pass filters (VNIR and SWIR up to 2200 nm). Absolute accuracy is better than 0.5% in VNIR spectral bands and 1% in SWIR spectral bands. Performances were cross checked with other laboratories. The first MSI diffuser for flight model was calibrated mid 2013 on CSL BRDF measurement bench. The calibration of the diffuser consists mainly in thermal vacuum cycles, BRDF uniformity characterisation and BRDF angular characterisation. The total amount of measurement for the first flight model diffuser corresponds to more than 17500 BRDF acquisitions. Performance results are discussed in comparison with requirements.

Post-conflict health reconstruction: search for a policy.

PubMed

Rubenstein, Leonard S

2011-10-01

Despite increasing experience in health reconstruction in societies emerging from conflict, the policy basis for investing in the development of equitable and effective health systems in the wake of war remains unsettled. Consideration of post-conflict health reconstruction is almost entirely absent in donor policies on global health. Practically by default, health programmes are seen increasingly as an element of stabilisation and security interventions in the aftermath of armed conflict. That perspective, however, lacks an evidence base and can skew health programmes towards short-term security and stabilisation goals that have a marginal impact and violate the principles of equity, non-discrimination, and quality, which are central to sound health systems and public acceptance of them. A better approach is to ground policy in legitimacy, viewing health both as a core social institution and one that, if developed according to human rights principles, including equity, non-discrimination, participation and accountability, can advance the effectiveness and the quality of governance in the emerging state. © 2011 The Author(s).

Few employment programmes exist to support forensic service users with severe mental health problems and a criminal history. Little is known about how best to achieve this. The Employment and Social Inclusion Project (ESIP) was developed and piloted to support forensic service users into employment and vocational activities. This pilot service evaluation aimed to assess the number of service users who secured employment/vocational activities and explored services users' and staff experiences. Quantitative data were collected to record the characteristics of participating service users and how many secured employment and engaged in vocational activities. Eighteen qualitative interviews were conducted with service users and staff. Fifty-seven service users engaged with the project, most were men (93.0%) and previously employed (82.5%). Four service users (7.0%) secured paid competitive employment. Eight (14.0%) gained other paid employment. Tailored one-to-one support to increase skills and build confidence was an important feature of the project. Creation of a painting and decorating programme offered training and paid/flexible work. This exploratory project achieved some success in assisting forensic service users into paid employment. Further research to identify what works well for this important group will be of great value.

Enhanced recovery clinical education programme improves quality of post-operative care

PubMed Central

McDonald, Ruth

2015-01-01

Quality is the driving principle of Enhanced Recovery (ER). It improves the patient experience by getting patients better sooner and changes clinical practice to make care safer and more efficient. As a consequence of ER patients spend less time in hospital. A successful ER programme began to fail after organisational restructuring and staff changes. Patients did not meet their ER goals and length of stay (LOS) increased. An ER nurse was appointed to get the programme back on track. This involved a multidisciplinary approach to an ER clinical education programme. The programme aimed to develop knowledge of the physiology of post-operative recovery and the evidence underpinning the interventions required. This was considered crucial to secure longer term staff engagement while avoiding unthinking protocol driven compliance. Success of the education programme was measured by improved outcomes in patient LOS and readmission statistics. During the four months of the clinical education programme there were no significant changes in monthly LOS. At six months post implementation of the programme there was a reduction in LOS of 0.6 days compared to the previous six months. At 12 months there was a reduction in 1.1 days compared with previous 12 months. There was a mean reduction of 28 day readmissions for all elective gynaecology surgery of 1.1 patients per month in the 12 months post programme implementation compared to the 12 months before. Delivering a multidisciplinary participatory education programme improved overall understanding of ER, and achieved sustained improvement in ER for patient benefit. PMID:26734343

Schönfeldt, Hettie C; Hall, Nicolette; Pretorius, B

2018-01-01

Most governments have committed to the set of Sustainable Development Goals established by the United Nations (UN) to be achieved by 2030. Subsequently the governments have drafted, or are in process of drafting, policies and programmes which aim to answer to these global requests. South Africa provides a unique case study: despite economic growth, undernutrition has not improved when compared to other industrialised nations, while at the same time, diet-related non-communicable diseases and obesity have exponentially increased. Access to healthy food is a constitutional right of all South Africans, and towards increasing food security and improving population health, various policies, programmes and regulations have been developed and implemented by the government to rectify the situation. The paper presents an overview of food composition within these public health policies, programmes and regulations and unpacks the important role of accurate food composition data.

Turkish children between the ages of 10-14 who either never enrolled in primary education, dropped out of school, or were at least three years behind their peers had the opportunity of joining an accelerated learning programme. It was developed by the Turkish Ministry of National Education General Directorate of Primary Education as a response to the urgent need to secure these children's right to education. The programme, called "Catch-up Education Programme" (CEP), was implemented between September 2008 and 2013 in collaboration with the United Nations Children's Fund (UNICEF) to enable those children to complete several grades in a short time and then to continue their education with their peers. This paper presents the findings of a study, conducted in 2010, reviewing the challenges and opportunities experienced during the implementation process from the points of view of beneficiaries (pupils and parents) and implementers. The results are discussed in relation to educational policy and its implementation in general.

To identify the factors associated with food insecurity among Quilombolas communities in Brazil. An analysis of secondary data assessed in the 2011 Quilombolas Census was performed. The Brazilian Food Insecurity Measurement Scale (Escala Brasileira de Insegurança Alimentar, EBIA) was used to assess household food security status. Sociodemographic conditions and access to social programmes and benefits were also evaluated. National survey census from recognized Quilombolas Brazilian territories. Quilombolas households (n 8846). About half (47·8 %) of the Quilombolas lived in severely food-insecure households, with the North and Northeast regions facing the most critical situation. Households located in North Brazil, whose head of the family had less than 4 years of education, with a monthly per capita income below $US 44, without adequate sanitation and without adequate water supply had the greatest chance of experiencing moderate or severe food insecurity. Households that had access to a water supply programme for dry regions (Programa Cisternas) and an agricultural harvest subsidy programme (Programa Garantia Safra) had less chance of experiencing moderate and severe food insecurity. Households that did not have access to health care (Programa Saúde da Família) had greater chance of suffering from moderate or severe food insecurity. Interventions are urgently needed to strengthen and promote public policies aimed to improve living conditions and food security in Quilombolas communities.

The European Union (EU) Decision (1082/2013/EU) on serious cross border threats to health was adopted by the European Parliament in November 2013, in recognition of the need to strengthen the capacity of Member States to coordinate the public health response to cross border threats, whether from biological, chemical, environmental events or events which have an unknown origin. Although mechanisms have been in place for years for reporting cross border health threats from communicable diseases, this has not been the case for incidents involving chemicals and/or environmental events. A variety of collaborative EU projects have been funded over the past 10 years through the Health Programme to address gaps in knowledge on health security and to improve resilience and response to major incidents involving chemicals. This paper looks at the EU Health Programme that underpins recent research activities to address gaps in resilience, planning, responding to and recovering from a cross border chemical incident. It also looks at how the outputs from the research programme will contribute to improving public health management of transnational incidents that have the potential to overwhelm national capabilities, putting this into context with the new requirements as the Decision on serious cross border threats to health as well as highlighting areas for future development.

The paper gives a brief summary of the SEISMED project and the particular role played by the Reference Centres. Details are given of the hardware and application systems in use in the Royal Hospitals (NHS) Trust (RHT), one of the SEISMED Reference Centres. It proposes, without verification, a definition of a Security Culture based on three criteria. These are suggested to be the "Awareness" the "Acceptance" and the "Actions" of the management and staff to improve Information Systems Security throughout the RHT. The way that "Awareness" was increased is shown by the specific initiatives commenced as a result of a CRAMM Risk Analysis and the management and staff training programmes. The specific initiatives mentioned include, an Information Systems Security Policy, a contingency and disaster recovery plan, improvements in the physical protection of equipment and changes to the method of access control. The "Acceptance" by the staff of these measures is considered and the success or failure of "Developing A Security Culture" examined. The role of SEISMED in this process is assessed.

2015-04-01

India's poor performance on critical food and nutrition security indicators despite substantial economic prosperity has been widely documented. These failings not only hamper national progress, but also contribute significantly to the global undernourished population, particularly children. While the recently passed National Food Security Act 2013 adopts a life-cycle approach to expand coverage of subsidized food grains to the most vulnerable households and address food security, there remains much to be desired in the legislation. Access to adequate food for 1.24 billion people is a multifaceted problem requiring an interconnected set of policy measures to tackle the various factors affecting food and nutrition security in India. In the present opinion paper, we discuss a fivefold strategy that incorporates a life-cycle approach, spanning reproductive health, bolstering citizen participation in existing national programmes, empowering women, advancing agriculture and better monitoring the Public Distribution System in order to fill the gaps in both access and adequacy of food and nutrition.

Security risk assessment: applying the concepts of fuzzy logic.

PubMed

Bajpai, Shailendra; Sachdeva, Anish; Gupta, J P

2010-01-15

Chemical process industries (CPI) handling hazardous chemicals in bulk can be attractive targets for deliberate adversarial actions by terrorists, criminals and disgruntled employees. It is therefore imperative to have comprehensive security risk management programme including effective security risk assessment techniques. In an earlier work, it has been shown that security risk assessment can be done by conducting threat and vulnerability analysis or by developing Security Risk Factor Table (SRFT). HAZOP type vulnerability assessment sheets can be developed that are scenario based. In SRFT model, important security risk bearing factors such as location, ownership, visibility, inventory, etc., have been used. In this paper, the earlier developed SRFT model has been modified using the concepts of fuzzy logic. In the modified SRFT model, two linguistic fuzzy scales (three-point and four-point) are devised based on trapezoidal fuzzy numbers. Human subjectivity of different experts associated with previous SRFT model is tackled by mapping their scores to the newly devised fuzzy scale. Finally, the fuzzy score thus obtained is defuzzyfied to get the results. A test case of a refinery is used to explain the method and compared with the earlier work.

Creating meaningful business continuity management programme metrics.

PubMed

Strong, Brian

2010-11-01

The popular axiom, 'what gets measured gets done', is often applied in the quality management and continuous improvement disciplines. This truism is also useful to business continuity practitioners as they continually strive to prove the value of their organisation's investment in a business continuity management (BCM) programme. BCM practitioners must also remain relevant to their organisations as executives focus on the bottom line and maintaining stakeholder confidence. It seems that executives always find a way, whether in a hallway or elevator, to ask BCM professionals about the company's level of readiness. When asked, they must be ready with an informed response. The establishment of a process to measure business continuity programme performance and organisational readiness has emerged as a key component of US Department of Homeland Security 'Voluntary Private Sector Preparedness (PS-Prep) Program' standards where the overarching goal is to improve private sector preparedness for disasters and emergencies. The purpose of this paper is two-fold: to introduce continuity professionals to best practices that should be considered when developing a BCM metrics programme as well as providing a case study of how a large health insurance company researched, developed and implemented a process to measure BCM programme performance and company readiness.

European initiatives to develop information systems in oceanography

Le Grand, P.

2009-04-01

Various initiatives are currently in preparation or ongoing at the European level to improve information systems in Earth Sciences and oceanographic systems are at the forefront of these efforts. Europe is playing a leading role in the Group on Earth Observation (GEO) that aims to implement the Global Earth Observation System of Systems (GEOSS). The GEO Architecture and Data Committee, oversees the development of the GEOSS Common Infrastructure (GCI) which consists of a web-based portal, a clearinghouse for searching data, information and services, registries containing information about GEOSS components and associated standards and best practices. This development is detailed in the various tasks of the GEO Work Plan . Several European projects in the marine domain funded under the research framework program participate in the development of the GEOSS. EMODNET is another initiative to develop a system that will allow a better identification and access to marine data that are being collected, that will permit the identification of data gaps and that will shape a data collection and monitoring infrastructure directly suited to multiple applications. A number of measures have already been taken at EU level - the INSPIRE Directive obliges Member States to facilitate discovery of data holdings, the Environmental Information Directive requires them to release the data when asked, the Public Sector Information Directive facilitates the re-use of public data and the revised Data Collection Regulation has improved the availability of fisheries data. Moreover, prototype marine data catalogues and quality procedures for measurement laboratories have been developed through successive EU research programmes. EMODNET is complementary to other EU initiatives in the marine domain. Parameters made available through EMODNET will facilitate the GMES marine core service which aims to deliver both short term and seasonal forecasts, hindcasts, nowcasts, and time series and climate change scenario simulations. EMODNET will provide the access to raw and processed data necessary to calculate the indicators that Member States are obliged to provide through WISE-Marine to meet the requirements of the Marine Strategy Framework Directive. Moving to the definitive EMODNET will require significant funding. Given that EMODNET is very much focused on a sea-basin scale and given the impetus accorded to territorial cohesion by the EU maritime policy, discussions will begin to determine whether cohesion funding could support the initiative. At the same time moves will begin to integrate EMODNET with initiatives under the EU's research infrastructure programmes and the Common Fisheries Policy Data Collection Regulation. The objective is to achieve by 2014 an operational and sustainable EMODNET with earmarked funding and an agreed governance structure.

2018-06-01

In the past decade Europe has been facing rising security threats, ranging from climate change, migrations, nearby conflicts and crises, to terrorism. The demand to tackle these critical challenges is increasing in Member States. Space is already contributing, and could further contribute with already existing systems and future ones. The increasing need for security in Europe and for safety and security of Europe's space activities has led to a growing number of activities in ESA in various domains. It has also driven new and strengthened partnerships with security stakeholders in Europe. At the European level, ESA is collaborating closely with the main European institutions dealing with space security. In addition, as an organisation ESA has evolved to conduct security-related projects and programmes and to address the threats to its own activities, thereby securing the investments of the Member States. Over the past years the Agency has set up a comprehensive regulatory framework in order to be able to cope with security related requirements. Over the past years, ESA has increased its exchanges with its Member States. The paper presents main elements of the ESA's policy on space and security. It introduces the current European context for space and security, the European goals in this domain and the specific objectives to which the Agency intends to contribute. Space and security in the ESA context is set out under two components: a) security from space and b) security in space, including the security of ESA's own activities (corporate security and the security of ESA's space missions). Subsequently, ESA's activities are elaborated around these two pillars, composed of different activities conducted in the most appropriate frameworks and in coordination with the relevant stakeholders and shareholders.

Tobacco point‐of‐purchase promotion: examining tobacco industry documents

PubMed Central

Lavack, Anne M; Toth, Graham

2006-01-01

In the face of increasing media restrictions around the world, point‐of‐purchase promotion (also called point‐of‐sale merchandising, and frequently abbreviated as POP or POS) is now one of the most important tools that tobacco companies have for promoting tobacco products. Using tobacco industry documents, this paper demonstrates that tobacco companies have used point‐of‐purchase promotion in response to real or anticipated advertising restrictions. Their goal was to secure dominance in the retail setting, and this was achieved through well‐trained sales representatives who offered contracts for promotional incentive programmes to retailers, which included the use of point‐of‐sale displays and merchandising fixtures. Audit programmes played an important role in ensuring contract enforcement and compliance with a variety of tobacco company incentive programmes. Tobacco companies celebrated their merchandising successes, in recognition of the stiff competition that existed among tobacco companies for valuable retail display space. PMID:16998172

Many important social determinants of health are also the focus for social policies. Welfare states contribute to the resources available for their citizens through cash transfer programmes and subsidised services. Although all rich nations have welfare programmes, there are clear cross-national differences with respect to their design and generosity. These differences are evident in national variations in poverty rates, especially among children and elderly people. We investigated to what extent variations in family and pension policies are linked to infant mortality and old-age excess mortality. Infant mortality rates and old-age excess mortality rates were analysed in relation to social policy characteristics and generosity. We did pooled cross-sectional time-series analyses of 18 OECD (Organisation for Economic Co-operation and Development) countries during the period 1970-2000 for family policies and 1950-2000 for pension policies. Increased generosity in family policies that support dual-earner families is linked with lower infant mortality rates, whereas the generosity in family policies that support more traditional families with gainfully employed men and homemaking women is not. An increase by one percentage point in dual-earner support lowers infant mortality by 0.04 deaths per 1000 births. Generosity in basic security type of pensions is linked to lower old-age excess mortality, whereas the generosity of earnings-related income security pensions is not. An increase by one percentage point in basic security pensions is associated with a decrease in the old age excess mortality by 0.02 for men as well as for women. The ways in which social policies are designed, as well as their generosity, are important for health because of the increase in resources that social policies entail. Hence, social policies are of major importance for how we can tackle the social determinants of health.

Studying rare outcomes, new interventions and diverse populations often requires collaborations across multiple health research partners. However, transferring healthcare research data from one institution to another can increase the risk of data privacy and security breaches. A working group of multi-site research programmers evaluated the need for tools to support data security and data privacy. The group determined that data privacy support tools should: 1) allow for a range of allowable Protected Health Information (PHI); 2) clearly identify what type of data should be protected under the Health Insurance Portability and Accountability Act (HIPAA); and 3) help analysts identify which protected health information data elements are allowable in a given project and how they should be protected during data transfer. Based on these requirements we developed two performance support tools to support data programmers and site analysts in exchanging research data. The first tool, a workplan template, guides the lead programmer through effectively communicating the details of multi-site programming, including how to run the program, what output the program will create, and whether the output is expected to contain protected health information. The second performance support tool is a checklist that site analysts can use to ensure that multi-site program output conforms to expectations and does not contain protected health information beyond what is allowed under the multi-site research agreements. Together the two tools create a formal multi-site programming workflow designed to reduce the chance of accidental PHI disclosure.

Accessibility of summer meals and the food insecurity of low-income households with children.

Miller, Daniel P

2016-08-01

Almost no previous research has examined the impact of the US Department of Agriculture's (USDA) Summer Food Service Program and related Seamless Summer Option, which provide meals and snacks to low-income children over the summer. The present study investigated whether geographic accessibility of summer meals programme sites (a proxy for programme participation) was associated with food insecurity for low-income households. The study used data from the California Health Interview Survey (CHIS) and administrative data on summer meals sites in California. Geocoding was used to calculate driving time between CHIS households and nearby summer meals sites. Geographic accessibility was measured using a gravity model, which accounted for the spatially distributed supply of and demand for summer meals. Food insecurity and very low food security were measured using a standard six-item measure from the USDA. Low-income families with children (n 5394). A representative surveillance study of non-institutionalized households in California. Geographic accessibility was not associated with food insecurity. However, geographic accessibility was associated with a significantly lower probability of very low food security in the full sample and among households with younger children and those living in less urban areas. The USDA's summer meals programme may be effective at reducing the most severe form of food insecurity for low-income households with children. Expanding the number of summer meals sites, the number of meals served at sites and sites' hours of operation may be effective strategies to promote nutritional health over the summer months.

Surveillance of borders, coastlines, and harbours (SOBCAH): a European commission preparatory action on security research

Clarke, David J.; Davis, Eric; Varco, Alan G.

2008-10-01

Surveillance Of Borders Coastlines And Harbours (SOBCAH ) is becoming increasingly challenging in Europe due to the expansion of new European borders coupled with the increased risks from the potential quantity and variety of terrorist activities. SOBCAH was an 18-month programme undertaken as a European Commission funded Preparatory Action in the field of Security Research (PASR) initiative to identify and demonstrate improvements in security; initially focusing on techniques to maximise the surveillance and detection effectiveness of existing sensor systems and technologies. This paper discusses the rationale in identifying the requirements, establishing a system architecture and the findings of building a security system demonstrator that underwent trials in the Port of Genoa, Italy in July 2007. It will provide an overview of the main drivers for a European-wide concept to standardise the development of enhanced border security systems. The paper will focus on techniques employed in the demonstrator to maximise the intelligence gathered from many disparate sensor sources without burdening the work load of the operators; providing enhanced situational awareness of the threat environment.

FPGA implementation cost and performance evaluation of IEEE 802.11 protocol encryption security schemes

The explosive growth of internet and consumer demand for mobility has fuelled the exponential growth of wireless communications and networks. Mobile users want access to services and information, from both internet and personal devices, from a range of locations without the use of a cable medium. IEEE 802.11 is one of the most widely used wireless standards of our days. The amount of access and mobility into wireless networks requires a security infrastructure that protects communication within that network. The security of this protocol is based on the wired equivalent privacy (WEP) scheme. Currently, all the IEEE 802.11 market products support WEP. But recently, the 802.11i working group introduced the advanced encryption standard (AES), as the security scheme for the future IEEE 802.11 applications. In this paper, the hardware integrations of WEP and AES are studied. A field programmable gate array (FPGA) device has been used as the hardware implementation platform, for a fair comparison between the two security schemes. Measurements for the FPGA implementation cost, operating frequency, power consumption and performance are given.

Abstract The Antibiotics Smart Use (ASU) programme was introduced in Thailand as a model to promote the rational use of medicines, starting with antibiotics. The programme’s first phase consisted of assessing interventions intended to change prescribing practices; the second phase examined the feasibility of programme scale-up. Currently the programme is in its third phase, which centres on sustainability. This paper describes the concept behind ASU, the programme’s functional modalities, the development of its conceptual framework and the implementation of its first and second phases. To change antibiotic prescription practices, multifaceted interventions at the individual and organizational levels were implemented; to maintain behaviour change and scale up the programme, interventions at the network and policy levels were used. The National Health Security Office has adopted ASU as a pay-for-performance criterion, a major achievement that has led to the programme’s expansion nationwide. Despite limited resources, programme scale-up and sustainability have been facilitated by the promotion of local ownership and mutual recognition, which have generated pride and commitment. ASU is clearly a workable entry point for efforts to rationalize the use of medicines in Thailand. Its long-term sustainability will require continued local commitment and political support, effective auditing and integration of ASU into routine systems with appropriate financial incentives.

To investigate characteristics of exposure to violence in relation to food security status among female-headed households. Ongoing mixed-method participatory action study. Questions addressed food insecurity, public assistance, and maternal and child health. Grounded theory analysis of qualitative themes related to violence was performed. These themes were then categorized by food security status. Homes of low-income families in Philadelphia, PA, USA. Forty-four mothers of children under 3 years of age participating in public assistance programmes. Forty women described exposure to violence ranging from fear of violence to personal experiences with rape. Exposure to violence affected mental health, ability to continue school and obtain work with living wages, and subsequently the ability to afford food. Exposure to violence during childhood and being a perpetrator of violence were both linked to very low food security status and depressive symptoms. Ten of seventeen (59%) participants reporting very low food security described life-changing violence, compared with three of fifteen (20%) participants reporting low food security and four of twelve (33%) reporting food security. Examples of violent experiences among the very low food secure group included exposure to child abuse, neglect and rape that suggest exposure to violence is an important factor in the experience of very low food security. Descriptions of childhood trauma and life-changing violence are linked with severe food security. Policy makers and clinicians should incorporate violence prevention efforts when addressing hunger.

How does the interdisciplinary cooperation of psychiatric staff members change after a multiprofessional family systems training programme? Semi-structured interviews were conducted with 49 staff members. Quantitative questionnaires were used to assess burnout (Maslach Burnout Inventory, MBI) and team climate (Team-Klima-Inventar, TKI). The multiprofessional training intensifies interdisciplinary cooperation. It results in an increased appreciation of the nurses involved and in a redistribution of therapeutic tasks between nurses, psychologists and physicians. Staff burnout decreased during the research period, while task orientation and participative security within teams increased. The multiprofessional family systems training appears suitable to improve quality of patient care and interdisciplinary cooperation and to reduce staff burnout.

Secure TRNG with random phase stimulation

NASA Astrophysics Data System (ADS)

Wieczorek, Piotr Z.

2017-08-01

In this paper a novel TRNG concept is proposed which is a vital part of cryptographic systems. The proposed TRNG involves phase variability of a pair of ring oscillators (ROs) to force the multiple metastable events in a flip-flop (FF). In the solution, the ROs are periodically activated to ensure the violation of the FF timing and resultant state randomness, while the TRNG circuit adapts the structure of ROs to obtain the maximum entropy and circuit security. The TRNG can be implemented in inexpensive re-programmable devices (CPLDs or FPGAs) without the use of Digital Clock Managers (DCMs). Preliminary test results proved the circuit's immunity to the intentional frequency injection attacks.

2013-01-01

The combined effects of population growth, increasing demands for water to support agriculture, energy security, and industrial expansion, and the challenges of climate change give rise to an urgent need to carefully monitor and assess trends and variations in water resources. Doing so will ensure that sustainable access to adequate quantities of safe and useable water will serve as a foundation for water security. Both satellite and in situ observations combined with data assimilation and models are needed for effective, integrated monitoring of the water cycle's trends and variability in terms of both quantity and quality. On the basis of a review of existing observational systems, we argue that a new integrated monitoring capability for water security purposes is urgently needed. Furthermore, the components for this capability exist and could be integrated through the cooperation of national observational programmes. The Group on Earth Observations should play a central role in the design, implementation, management and analysis of this system and its products.

Aims and method To evaluate differences between male patients in secure psychiatric settings in the UK based on whether they are detained under civil or forensic sections of the Mental Health Act 1983. A cohort of patients discharged from a secure psychiatric hospital were evaluated for length of stay and frequency of risk-related incidents. Results Overall, 84 patients were included in the study: 52 in the forensic group and 32 in the civil group. Civil patients had more frequent incidents of aggression, sex offending, fire-setting and vulnerability, whereas forensic patients had more frequent episodes of self-harm. Clinical implications Secure hospitals should ensure treatment programmes are tailored to each patient's needs. Civil patients require greater emphasis on treatment of their mental illness, whereas forensic patients have additional offence-related treatment needs. Regular liaison between forensic and general adult services is essential to help ensure patients can return to appropriate settings at the earliest opportunity in their recovery.

Global health programmes require extensive adaptation for implementation in conflict and post-conflict settings. Without such adaptations, both implementation success and diplomatic, international relations and other indirect outcomes may be threatened. Conversely, diplomatic successes may be made through flexible and responsive programmes. We examine adaptations and associated outcomes for malaria treatment and prevention programmes in Afghanistan. In conjunction with the completion of monitoring and evaluation activities for the Global Fund to Fight AIDS, Tuberculosis and Malaria, we reviewed adaptations to the structure, design, selection, content and delivery of malaria-related interventions in Afghanistan. Interviews were conducted with programme implementers, service delivery providers, government representatives and local stakeholders, and site visits to service delivery points were completed. Programmes for malaria treatment and prevention require a range of adaptations for successful implementation in Afghanistan. These include (1) amendment of educational materials for rural populations, (2) religious awareness in gender groupings for health educational interventions, (3) recruitment of local staff, educated in languages and customs, for both quality assurance and service delivery, (4) alignment with diplomatic principles and, thereby, avoidance of confusion with broader strategic and military initiatives and (5) amendments to programme 'branding' procedures. The absence of provision for these adaptations made service delivery excessively challenging and increased the risk of tension between narrow programmatic and broader diplomatic goals. Conversely, adapted global health programmes displayed a unique capacity to access potentially extremist populations and groups in remote regions otherwise isolated from international activities. A range of diplomatic considerations when delivering global health programmes in conflict and post-conflict settings are required in order to ensure that health gains are not offset by broader international relations losses through challenges to local cultural, religious and social norms, as well as in order to ensure the security of programme staff. Conversely, when global health programmes are delivered with international relations considerations in mind, they have the potential to generate unquantified diplomatic outcomes.

Assessing the relevance of neighbourhood characteristics to the household food security of low-income Toronto families.

Kirkpatrick, Sharon I; Tarasuk, Valerie

2010-07-01

Although the sociodemographic characteristics of food-insecure households have been well documented, there has been little examination of neighbourhood characteristics in relation to this problem. In the present study we examined the association between household food security and neighbourhood features including geographic food access and perceived neighbourhood social capital. Cross-sectional survey and mapping of discount supermarkets and community food programmes. Twelve high-poverty neighbourhoods in Toronto, Ontario, Canada. Respondents from 484 low-income families who had children and who lived in rental accommodations. Food insecurity was pervasive, affecting two-thirds of families with about a quarter categorized as severely food insecure, indicative of food deprivation. Food insecurity was associated with household factors including income and income source. However, food security did not appear to be mitigated by proximity to food retail or community food programmes, and high rates of food insecurity were observed in neighbourhoods with good geographic food access. While low perceived neighbourhood social capital was associated with higher odds of food insecurity, this effect did not persist once we accounted for household sociodemographic factors. Our findings raise questions about the extent to which neighbourhood-level interventions to improve factors such as food access or social cohesion can mitigate problems of food insecurity that are rooted in resource constraints. In contrast, the results reinforce the importance of household-level characteristics and highlight the need for interventions to address the financial constraints that underlie problems of food insecurity.

Food security and sustainability: can one exist without the other?

To position the concept of sustainability within the context of food security. An overview of the interrelationships between food security and sustainability based on a non-systematic literature review and informed discussions based principally on a quasi-historical approach from meetings and reports. International and global food security and nutrition. The Rome Declaration on World Food Security in 1996 defined its three basic dimensions as: availability, accessibility and utilization, with a focus on nutritional well-being. It also stressed the importance of sustainable management of natural resources and the elimination of unsustainable patterns of food consumption and production. In 2009, at the World Summit on Food Security, the concept of stability/vulnerability was added as the short-term time indicator of the ability of food systems to withstand shocks, whether natural or man-made, as part of the Five Rome Principles for Sustainable Global Food Security. More recently, intergovernmental processes have emphasized the importance of sustainability to preserve the environment, natural resources and agro-ecosystems (and thus the overlying social system), as well as the importance of food security as part of sustainability and vice versa. Sustainability should be considered as part of the long-term time dimension in the assessment of food security. From such a perspective the concept of sustainable diets can play a key role as a goal and a way of maintaining nutritional well-being and health, while ensuring the sustainability for future food security. Without integrating sustainability as an explicit (fifth?) dimension of food security, today's policies and programmes could become the very cause of increased food insecurity in the future.

HIV care and treatment providers across sub-Saharan Africa are integrating livelihood interventions to improve food security of their clientele. Many integrated HIV and livelihood programmes (IHLPs) require the formation and use of groups of HIV-infected/affected individuals as the operational target for programme interventions, indeed, virtually without exception the group is the focal point for material and intellectual inputs of IHLPs. We sought to critically examine the group approach to programming among IHLPs in Uganda, and to explore and problematise the assumptions underpinning this model. A case study approach to studying 16 IHLPs was adopted. Each IHLP was treated as a case comprising multiple in-depth interviews conducted with staff along the livelihood programme chain. Additionally, in-depth interviews were conducted with staff from The AIDS Support Organization (TASO), and with members of 71 HIV-infected TASO-registered client households. Our analysis reveals three important considerations in IHLP programming regarding the group-centred approach: (1) Group membership is widely held to confer benefits in the form of psycho-social and motivational support, particularly in empowering individuals to access HIV services and handle stigma. This is contrasted with the problem of stigma inherent in joining groups defined by HIV-status; (2) Membership in groups can bring economic benefits through the pooling of labour and resources. These benefits however need to be set against the costs of membership, when members are required to make contributions in the form of money, goods or labour; (3) Sharing of goods and labour in the context of group membership allow members to access benefits which would otherwise be inaccessible. In exchange, individual choice and control are diminished and problems of resources held in common can arise. While the group model can bring benefits to IHLP efficiency and by extension to food security, and other outcomes, its application needs to be carefully scrutinised at the individual programme level, in terms of whether it is an appropriate approach, and in terms of mitigating potentially adverse effects.

To evaluate the effectiveness of the Perinatal Continuing Education Programme (PCEP) in a Latin American country. We carried out a study within secondary and tertiary care, and rural Mexican Institute of Social Security (IMSS) hospitals on the Yucatan Peninsula. Participants were doctors, nurses and nursing assistants working with pregnant women and newborns at each hospital. The PCEP was translated into Spanish and then implemented between January 1998 and December 2001. Two nurses at each hospital were trained to co-ordinate the programme and the personnel were invited to participate. Participation involved purchasing the self-teaching books, study outside work hours and participation in skills demonstration and practice sessions. Evaluation included the percentage of personnel who participated in and those who completed the programme, an opinion survey of the programme, level of pre- and post-intervention knowledge, and the quality of neonatal care according to expert-recommended routines. Results were analysed with chi-square and Student's t-tests. A total of 65.3% of the 1421 people in the study population began the programme and 72% of those completed it. Improvement was observed in 14 of 23 (P<0.05) evaluated neonatal care practices. Participants rated the written material as very clear and useful in daily practice. The PCEP is an effective strategy for improving the level of knowledge and perinatal care in all regional hospitals on the Yucatan Peninsula, Mexico. This initial application of the PCEP in a Spanish-speaking country was successful.

Underuse of anticoagulants in atrial fibrillation is known to increase the risk of stroke and is an international problem. The National Institute for Health Care and Excellence guidance CG180 seeks to reduce atrial fibrillation related strokes through prescriptions of Non-vitamin K antagonist Oral Anticoagulants. A quality improvement programme was established by the West of England Academic Health Science Network (West of England AHSN) to implement this guidance into General Practice. A realist evaluation identified whether the quality improvement programme worked, determining how and in what circumstances. Six General Practices in 1 region, became the case study sites. Quality improvement team, doctor, and pharmacist meetings within each of the General Practices were recorded at 3 stages: initial planning, review, and final. Additionally, 15 interviews conducted with the practice leads explored experiences of the quality improvement process. Observation and interview data were analysed and compared against the initial programme theory. The quality improvement resources available were used variably, with the training being valued by all. The initial programme theories were refined. In particular, local workload pressures and individual General Practitioner experiences and pre-conceived ideas were acknowledged. Where key motivators were in place, such as prior experience, the programme achieved optimal outcomes and secured a lasting quality improvement legacy. The employment of a quality improvement programme can deliver practice change and improvement legacy outcomes when particular mechanisms are employed and in contexts where there is a commitment to improve service. © 2018 John Wiley & Sons, Ltd.

Japan's anti-nuclear weapons policy misses its target, even in the war on terrorism.

PubMed

DiFilippo, Anthony

2003-01-01

While actively working to promote the abolition of all nuclear weapons from the world since the end of the cold war, Japan's disarmament policies are not without problems. Promoting the elimination of nuclear weapons as Japan remains under the US nuclear umbrella creates a major credibility problem for Tokyo, since this decision maintains a Japanese deterrence policy at the same time that officials push for disarmament. Tokyo also advocates a gradual approach to the abolition of nuclear weapons, a decision that has had no effect on those countries that have been conducting sub-critical nuclear testing, nor stopped India and Pakistan from carrying out nuclear tests. Consistent with Article 9 of the Constitution, the Japanese war-renouncing constitutional clause, Tokyo toughened Japan's sizeable Official Development Assistance (ODA) programme in the early 1990s. Because of the anti-military guidelines included in Japan's ODA programme, Tokyo stopped new grant and loan aid to India and Pakistan in 1998 after these countries conducted nuclear tests. However, because of the criticism Japan faced from its failure to participate in the 1991 Gulf War, Tokyo has been seeking a new Japanese role in international security during the post-cold war period. Deepening its commitment to the security alliance with the US, Tokyo has become increasingly influenced by Washington's global polices, including the American war on terrorism. After Washington decided that Pakistan would be a key player in the US war on terrorism, Tokyo restored grant and loan aid to both Islamabad and New Delhi, despite the unequivocal restrictions of Japan's ODA programme.

2015-05-01

The Indian space transportation programme has grown from strength to strength with the launching of sounding rockets in the 60's to the development of heavy lift vehicles for telecommunication satellites in the present decade. With the growing market confidence in Indian Space Research Organisation's ability to reliably deliver payloads to low Earth orbit with its Polar Satellite Launch Vehicle, there is an inherent opportunity for India to cater to the commercial market. The present work assesses the current launch capacity of India in retrospect of international launches and provides India's outlook for the space transportation in the current decade. Launch capacity correlation with the requirements within the Indian space programme as well as the current space transportation infrastructure have been considered to identify bottlenecks in catering to the current national requirements alongside securing a greater market share in the international launch market. The state of commercialisation of launch vehicle development has been presented to provide an overview of policy and organisational issues for commercialisation of space transportation in India.

Early childhood development programmes vary in coordination and quality, with inadequate and inequitable access, especially for children younger than 3 years. New estimates, based on proxy measures of stunting and poverty, indicate that 250 million children (43%) younger than 5 years in low-income and middle-income countries are at risk of not reaching their developmental potential. There is therefore an urgent need to increase multisectoral coverage of quality programming that incorporates health, nutrition, security and safety, responsive caregiving, and early learning. Equitable early childhood policies and programmes are crucial for meeting Sustainable Development Goals, and for children to develop the intellectual skills, creativity, and wellbeing required to become healthy and productive adults. In this paper, the first in a three part Series on early childhood development, we examine recent scientific progress and global commitments to early childhood development. Research, programmes, and policies have advanced substantially since 2000, with new neuroscientific evidence linking early adversity and nurturing care with brain development and function throughout the life course.

Issues in post-literacy

1989-12-01

While school enrolments have been rising, the absolute number of illiterates in the world has grown too. Eradication of adult illiteracy and universalization of primary education are hindered by high drop-out in schools and relapse into illiteracy among adults. Post-literacy programmes seek to stop this reversal by ensuring retention, application and continuation of literacy skills. The Unesco Institute for Education (UIE) has been researching and promoting post-literacy strategies since 1980, but finds that most projects do not include provision for post-literacy from the outset, despite the evident need. Those programmes which have been mounted use a variety of strategies, which UIE has analysed in 12 categories. The exact delimitation of the post-literacy stage in the lifelong education continuum differs from project to project, and the emphasis on individual or societal advance depends on local perceptions of the goals of development. Examples are given of successful programmes, and the challenges of increasing participation and motivation, securing adequate funding, and making efficient and flexible use of institutional facilities are discussed.

Global health diplomacy, 'smart power', and the new world order.

Kevany, Sebastian

2014-01-01

Both the theory and practice of foreign policy and diplomacy, including systems of hard and soft power, are undergoing paradigm shifts, with an increasing number of innovative actors and strategies contributing to international relations outcomes in the 'New World Order'. Concurrently, global health programmes continue to ascend the political spectrum in scale, scope and influence. This concatenation of circumstances has demanded a re-examination of the existing and potential effectiveness of global health programmes in the 'smart power' context, based on adherence to a range of design, implementation and assessment criteria, which may simultaneously optimise their humanitarian, foreign policy and diplomatic effectiveness. A synthesis of contemporary characteristics of 'global health diplomacy' and 'global health as foreign policy', grouped by common themes and generated in the context of related field experiences, are presented in the form of 'Top Ten' criteria lists for optimising both diplomatic and foreign policy effectiveness of global health programmes, and criteria are presented in concert with an examination of implications for programme design and delivery. Key criteria for global health programmes that are sensitised to both diplomatic and foreign policy goals include visibility, sustainability, geostrategic considerations, accountability, effectiveness and alignment with broader policy objectives. Though diplomacy is a component of foreign policy, criteria for 'diplomatically-sensitised' versus 'foreign policy-sensitised' global health programmes were not always consistent, and were occasionally in conflict, with each other. The desirability of making diplomatic and foreign policy criteria explicit, rather than implicit, in the context of global health programme design, delivery and evaluation are reflected in the identified implications for (1) international security, (2) programme evaluation, (3) funding and resource allocation decisions, (4) approval systems and (5) training. On this basis, global health programmes are shown to provide a valuable, yet underutilised, tool for diplomacy and foreign policy purposes, including their role in the pursuit of benign international influence. A corresponding alignment of resources between 'hard' and 'smart' power options is encouraged.

Real time test bed development for power system operation, control and cyber security

NASA Astrophysics Data System (ADS)

Reddi, Ram Mohan

The operation and control of the power system in an efficient way is important in order to keep the system secure, reliable and economical. With advancements in smart grid, several new algorithms have been developed for improved operation and control. These algorithms need to be extensively tested and validated in real time before applying to the real electric power grid. This work focuses on the development of a real time test bed for testing and validating power system control algorithms, hardware devices and cyber security vulnerability. The test bed developed utilizes several hardware components including relays, phasor measurement units, phasor data concentrator, programmable logic controllers and several software tools. Current work also integrates historian for power system monitoring and data archiving. Finally, two different power system test cases are simulated to demonstrate the applications of developed test bed. The developed test bed can also be used for power system education.

Italy is one of the European countries most affected by landslides counting over 486,000 mass movements with a total area of 20,700 square kilometres equal to 6.9% of the national territory. Moreover Italy is a densely urbanized country: 8101 municipalities, about 200 inhabitants per sq. km, 16,000 km of rail network and 180,000 km of road network. Landslides caused more than 5000 fatalities in the last century and considerable damage to urban areas, transport infrastructure and facilities, environmental and cultural heritage. The aim of this work is to estimate the population exposed to landslide risk in Italy. The input data are: the Italian Landslide Inventory, the Italian Population Census data and the high-resolution Artificial surfaces-Imperviousness Layer (Geoland2). The Italian Landslide Inventory (Progetto IFFI) realised by ISPRA (Italian National Institute for Environmental Protection and Research) and the Regions and Self-governing Provinces, identifies landslides occurred in the national territory in accordance with standardized methods and using a detailed landslide mapping (1:10,000 scale). The 14th Population Census, made by ISTAT (Italian National Institute of Statistics) in 2001, contains data of resident population for the 382,534 census tracts in which Italy is divided. The pan-European high-resolution (HR) Artificial surfaces-Imperviousness Layer, realized using remote sensing data within the GMES initiative (Global Monitoring for Environment and Security) by European Commission and European Space Agency, contains the degree of imperviousness (between 0 and 100%). GIS overlay of this information layer (20 x 20 m grid) with census tracts has allowed the spatialization of population within urban settlements of each census tract. This methodology has been particularly useful in the case of rural census tracts characterized by large surface area and low population density. The methodology could be also applied to estimate the population exposed to other natural, environmental or technological risks.

2012-06-01

Gas analysis systems having small size, low power, and high selectivity are badly needed for defense (detection of explosives and chemical warfare agents), homeland security, health care, and environmental applications. This paper presents a palm-size gas chromatography system having analysis times of 5-50sec, detection limits less than 1ppb, and an average power dissipation less than one watt. It uses no consumables. The three-chip fluidic system consists of a preconcentrator, a 25cm-3m separation column, and a chemi-resistive detector and is supported by a microcomputer and circuitry for programmable temperature control. The entire system, including the mini-pump and battery, occupies less than 200cc and is configured for use on autonomous robotic vehicles.

Two meanings of personal responsibility are distinguished, and different policy options for promoting health and responsibility are presented. Key insights from research seeking to promote personal responsibility through health information and incentives are outlined and discussed with regard to their potential to improve health and reduce cost. Data is presented on the socioeconomic characteristics of incentive programme users. It is concluded that due to different factors the availability of data regarding the effectiveness of incentive programmes is unsatisfactory. Evaluation requirements set out in the German Social Security Code (SGB V) should focus not only on cost, but should also extend to changes in health status and the socioeconomic status of users: provisions should be revised accordingly.

Objective To analyse the advanced systems of urology residency in the developed world, to compare them to a system in the developing world, and thereby identify the shortcomings and make recommendations to improve residency programmes for urology in the Kurdistan Region of Iraq. Methods A survey was conducted amongst the urology Residents (55) in the three governorates of the Kurdistan Region of Iraq, to assess the accessibility of the training programme, the types of the residency programmes, skills acquisition, the use of modern technology for teaching and assessment, the environment of the settings of practice, and the status of research in their training. Results An overwhelming majority (88%) of trainees reported difficulty in securing a training position. A high proportion (43%) felt disappointed at the beginning of their training. There is no unified curriculum of training, and more than two-thirds of the respondents reported a lack of a proper evidence-based medical education. There is no formal subspecialty training programme. Of the respondents, 65% referred to the difficulties in the environment for training, and that there was a low level of research involvement (12%). Conclusions Urology training is not easily accessible, there is no unified programme of residency, there are limited facilities, and a minimal assessment of practical skills. The environment for practice needs enormous improvements and a strong foundation for research should be created. PMID:26019913

Wang, Haixin; Bai, Guoqiang; Chen, Hongyi

2010-03-01

The last few years have seen many significant progresses in the field of application-specific processors. One example is network security processors (NSPs) that perform various cryptographic operations specified by network security protocols and help to offload the computation intensive burdens from network processors (NPs). This article presents a high performance NSP system architecture implementation intended for both internet protocol security (IPSec) and secure socket layer (SSL) protocol acceleration, which are widely employed in virtual private network (VPN) and e-commerce applications. The efficient dual one-way pipelined data transfer skeleton and optimised integration scheme of the heterogenous parallel crypto engine arrays lead to a Gbps rate NSP, which is programmable with domain specific descriptor-based instructions. The descriptor-based control flow fragments large data packets and distributes them to the crypto engine arrays, which fully utilises the parallel computation resources and improves the overall system data throughput. A prototyping platform for this NSP design is implemented with a Xilinx XC3S5000 based FPGA chip set. Results show that the design gives a peak throughput for the IPSec ESP tunnel mode of 2.85 Gbps with over 2100 full SSL handshakes per second at a clock rate of 95 MHz.

A form of relapse prevention for men in a high security hospital.

Newton, Liam; Coles, Dawn; Quayle, Marie

Marlatt and Gordon's relapse prevention model has evolved, and been applied to many repetitive problem behaviours, including drug use, gambling and sexual offending. High security hospital patients often present with a number of such behaviours. To evaluate a relapse prevention group in one high security hospital. Nine patients were selected on clinical need for the group. In a naturalistic study design, each completed several self-report questionnaires pre- and post-group. Analysis of group results demonstrated a significant increase in guilt and acceptance of responsibility for offences (GBAI ratings), and reduced endorsement of pro-offending thinking styles (PICTS). Movement towards increased empathy, and decreased impulsivity and venturesomeness, did not reach significance. All participants showed some changes in desired directions but effects were small. Both relapse prevention and its evaluation are limited in high security hospitals by the restricted opportunities for testing out new skills. The feasibility of delivering an RP programme and evaluating it in high security has nevertheless been established. The small effects found may be promising, and suggest both justification and need for a randomized controlled trial of this approach in that setting. Copyright (c) 2005 John Wiley & Sons, Ltd.

Situational analysis of infant and young child nutrition policies and programmatic activities in Mali.

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals. Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with a situational analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse and interpret available information on infant and young child feeding, and the nutrition situation of children <2 years of age in Mali, as one of the six targeted countries. Between June and September 2008, key informants responsible for conducting IYCN-related activities in Mali were interviewed, and 117 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, screening and management of acute malnutrition, prevention of mother-to-child transmission of HIV, food security, and hygienic practices. Most of the key IYCN topics were addressed in national policies, training materials, and programme documents. Information on the national coverage and impact of these programmes is generally not available. Exclusive breastfeeding (<6 months) has increased in Mali, but no studies identified the contributors to this increase. Despite improvements in breastfeeding practices, optimal infant, and young child feeding is still practiced among too few young children in Mali. Several research articles were identified, but few of these were linked to programme development. Some programme monitoring and evaluation reports were available, but few of these were rigorous enough to identify whether IYCN-specific programme components were implemented as designed or were achieving desired outcomes. Therefore, we could not confirm which programmes contributed to reported improvements. Monitoring of programmes managing malnutrition identified gaps in human and institutional capacities to fully carry out intended interventions and the government has recognized the overall lack of adequate numbers of health care providers to carry out necessary programmes in Mali, of which nutrition programmes are a part. The policy and programme framework is well established for support of optimal IYCN practices, but greater resources and capacity building are needed to: (i) conduct necessary research to adapt training materials and programme protocols to programmatic needs; (ii) implement rigorous monitoring and evaluation that identify effective programme components; and (iii) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

External Quality Assessment (EQA) surveys performed by the World Health Organization Regional Office for Africa (WHO AFRO) revealed the need for the strengthening of public health microbiology laboratories, particularly for testing of epidemic-prone diseases in the African Region. These surveys revealed common issues such as supply chain management, skilled personnel, logistical support and overall lack of quality standards. For sustainable improvements to health systems as well as global health security, deficiencies identified need to be actively corrected through robust quality assurance programmes and implementation of laboratory quality management systems. Given all the pathogens of public health importance, an external quality assessment programme with a focus on vaccine-preventable diseases and emerging and re-emerging dangerous pathogens is important, and should not be stand-alone, but integrated within laboratory networks as seen in polio, measles, yellow fever and rubella. In 2015, WHO AFRO collaborated with the US Centers for Disease Control and Prevention, the London School of Hygiene & Tropical Medicine and partners in a series of consultations with countries and national and regional EQA providers for the development of quality assurance models to support HIV point-of-care testing and monitoring. These consultations revealed similar challenges as seen in the WHO AFRO surveys. WHO AFRO brought forth its experience in implementing quality standards for health programmes, and also opened discussions on how lessons learned through such established programmes can be utilised to supporting and strengthening the introduction of early infant diagnosis of HIV and viral load point-of-care testing. An optimised external quality assessment programme will impact the ability of countries to meet core capacities, providing improved quality management systems, improving the confidence of diagnostic network services in Africa, and including capacities to detect events of international public health importance.

The ISTIMES project: a new integrated system for monitoring critical transport infrastructures interested by natural hazards

NASA Astrophysics Data System (ADS)

Proto, Monica; Massimo, Bavusi; Francesco, Soldovieri

2010-05-01

The research project "Integrated System for Transport Infrastructure surveillance and Monitoring by Electromagnetic Sensing" (ISTIMES), was approved in the 7th Framework Programme, in the Joint Call ICT and Security and started on 1st July 2009. The purpose of ISTIMES project is to design, assess and promote an ICT-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring in order to achieve the critical transport infrastructures more reliable and safe. The transportation sector's components are susceptible to the consequences of natural disasters and can also be attractive as terrorist targets. The sector's size, its physically dispersed and decentralized nature, the many public and private entities involved in its operations, the critical importance of cost considerations, and the inherent requirement of convenient accessibility to its services by all users - make the transportation particularly vulnerable to security and safety threats. As well known, the surface transportation system consists of interconnected infrastructures including highways, transit systems, railroads, airports, waterways, pipelines and ports, and the vehicles, aircraft, and vessels that operate along these networks. Thus, interdependencies exist between transportation and nearly every other sector of the economy and the effective operation of this system is essential to the European economic productivity; therefore, transportation sector protection is of paramount importance since threats to it may impact other industries that rely on it. The system exploits an open network architecture that can accommodate a wide range of sensors, static and mobile, and can be easily scaled up to allow the integration of additional sensors and interfacing with other networks. It relies on heterogeneous state-of-the-art electromagnetic sensors, enabling a self-organizing, self-healing, ad-hoc networking of terrestrial sensors, supported by specific satellite measurements. The integration of electromagnetic technologies with new ICT information and telecommunications systems enables remotely controlled monitoring and surveillance and real time data imaging of the critical transport infrastructures. Thus, the proposal will concern also with the development of tools for handling, analysing and processing large data volume (Information Fusion) and then providing information and performing behaviour prediction in a quick, easy and intuitive way (Situation Awareness). The proposal is based on several independent non-invasive imaging technologies based on electromagnetic sensing. Sensor cross validation, synergy and new data fusion and correlation schemes will permit a multi-method, multi-resolution and multi-scale electromagnetic detection and monitoring of surface and subsurface changes of the infrastructure. According to GMES and European Spatial Data Infrastructure (ESDI) initiatives, the system will adopt open architectures and will make efforts to achieve full interoperability. The system will be tested on two very challenging test beds such as: a highway-bridge and a railway tunnel. The system will be based on clear end-user requirements, coming from representative end-users and technological choices will be based on a long term cost-benefit analysis. Then, a dissemination plan was included into the project to encourage a wide range of public institutions and private companies to evaluate and adopt our approach for real-time control and distributed monitoring also in the more general framework of critical and civil infrastructure management and protection. Finally, an exploitation plan will develop for the commercialization of any derived technology, software, or monitoring concepts. ISTIMES project is carried out by an international partnership formed by nine partners coming from seven countries: Tecnologie per le Osservazioni della Terra (TeRN), Elsag Datamat (ED) and Dipartimento della Protezione Civile (DPC) from Italy, Eidgenoessische Materialpruefungs-und Forschungsanstalt (EMPA) from Switzerland, Laboratoire Central des Ponts et Chaussées (LCPC) from France, Lund University (ULUND) from Sweden, Tel Aviv University (TAU) from Israel, Territorial Data Elaboration (TDE) from Romania and Norsk Elektro Optikk (NEO) from Norway.

TeraSCREEN: multi-frequency multi-mode Terahertz screening for border checks

The challenge for any security screening system is to identify potentially harmful objects such as weapons and explosives concealed under clothing. Classical border and security checkpoints are no longer capable of fulfilling the demands of today's ever growing security requirements, especially with respect to the high throughput generally required which entails a high detection rate of threat material and a low false alarm rate. TeraSCREEN proposes to develop an innovative concept of multi-frequency multi-mode Terahertz and millimeter-wave detection with new automatic detection and classification functionalities. The system developed will demonstrate, at a live control point, the safe automatic detection and classification of objects concealed under clothing, whilst respecting privacy and increasing current throughput rates. This innovative screening system will combine multi-frequency, multi-mode images taken by passive and active subsystems which will scan the subjects and obtain complementary spatial and spectral information, thus allowing for automatic threat recognition. The TeraSCREEN project, which will run from 2013 to 2016, has received funding from the European Union's Seventh Framework Programme under the Security Call. This paper will describe the project objectives and approach.

'Never heard of it'- understanding the public's lack of awareness of a new electronic patient record.

PubMed

Bratan, Tanja; Stramer, Katja; Greenhalgh, Trisha

2010-12-01

The introduction of electronic patient records that are accessible by multiple providers raises security issues and requires informed consent - or at the very least, an opportunity to opt out. Introduction of the Summary Care Record (SCR) (a centrally stored electronic summary of a patient's medical record) in pilot sites in the UK was associated with low awareness, despite an intensive public information programme that included letters, posters, leaflets, and road shows. To understand why the public information programme had limited impact and to learn lessons for future programmes. Linguistic and communications analysis of components of the programme, contextualized within a wider mixed-method case study of the introduction of the SCR in pilot sites. Theoretical insights from linguistics and communication studies were applied. The context of the SCR pilots and the linked information programme created inherent challenges which were partially but not fully overcome by the efforts of campaigners. Much effort was put into designing the content of a mail merge letter, but less attention was given to its novelty, linguistic style, and rhetorical appeal. Many recipients viewed this letter as junk mail or propaganda and discarded it unread. Other components of the information programme were characterized by low visibility, partly because only restricted areas were participating in the pilot. Relatively little use was made of interpersonal communication channels. Despite ethical and legal imperatives, informed consent for the introduction of shared electronic records may be difficult to achieve through public information campaigns. Success may be more likely if established principles of effective mass and interpersonal communication are applied. © 2010 Blackwell Publishing Ltd.

Copernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European capacity for Earth Observation and Monitoring. Copernicus aims to provide a sustainable service for Ocean Monitoring and Forecasting validated and commissioned by users. From May 2015, the Copernicus Marine Environment Monitoring Service (CMEMS) is working on an operational mode through a contract with services engagement (result is regular data provision). Within CMEMS, the In Situ Thematic Assembly Centre (INSTAC) distributed service integrates in situ data from different sources for operational oceanography needs. CMEMS INSTAC is collecting and carrying out quality control in a homogeneous manner on data from providers outside Copernicus (national and international networks), to fit the needs of internal and external users. CMEMS INSTAC has been organized in 7 regional Dissemination Units (DUs) to rely on the EuroGOOS ROOSes. Each DU aggregates data and metadata provided by a series of Production Units (PUs) acting as an interface for providers. Homogeneity and standardization are key features to ensure coherent and efficient service. All DUs provide data in the OceanSITES NetCDF format 1.2 (based on NetCDF 3.6), which is CF compliant, relies on SeaDataNet vocabularies and is able to handle profile and time-series measurements. All the products, both near real-time (NRT) and multi-year (REP), are available online for every CMEMS registered user through an FTP service. On top of the FTP service, INSTAC products are available through Oceanotron, an open-source data server dedicated to marine observations dissemination. It provides services such as aggregation on spatio-temporal coordinates and observed parameters, and subsetting on observed parameters and metadata. The accuracy of the data is checked on various levels. Quality control procedures are applied for the validity of the data and correctness tests for the metadata of each NetCDF file. The quality control procedures for the data include different routines for NRT and REP products. Key Performance Indicators (KPI) for monitoring purposes are also used in Copernicus. They allow a periodic monitoring of the availability, quantity and quality of the INSTAC data integrated in the NRT products. Statistical reports are generated on quarterly and yearly basis to provide more visibility on the coverage in space and time of the INSTAC NRT and REP products, as well as information on their quality. These reports are generated using Java and Python procedures developed within the INSTAC group. One of the most critical tasks for the DUs is to generate NetCDF files compliant with the agreed format. Many tools and programming libraries have been developed for that purpose, for instance Unidata Java Library. These tools provide NetCDF data management capabilities including creation, reading and modification. Some DUs have also developed regional data portals which offer useful information for the users including data charts, platforms availability through interactive maps, KPI and statistical figures and direct access to the FTP service. The proposed presentation will detail Copernicus in situ data service and the monitoring tools that have been developed by the INSTAC group.

2010-05-01

GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) is a European Commission (EC)-funded project, kicked-off early 2008 lead by ESA; partners include Space Agencies (DLR, ASI, CNES), both space and no-space data providers such as ENEA (I), Infoterra (UK), K-SAT (N), NILU (N), JRC (EU) and industry as Elsag Datamat (I), CS (F) and TERRADUE (I). GENESI-DR intends to meet the challenge of facilitating "time to science" from different Earth Science disciplines in discovery, access and use (combining, integrating, processing, …) of historical and recent Earth-related data from space, airborne and in-situ sensors, which are archived in large distributed repositories. In fact, a common dedicated infrastructure such as the GENESI-DR one permits the Earth Science communities to derive objective information and to share knowledge in all environmental sensitive domains over a continuum of time and a variety of geographical scales so addressing urgent challenges such as Global Change. GENESI-DR federates data, information and knowledge for the management of our fragile planet in line with one of the major goals of the many international environmental programmes such as GMES, GEO/GEOSS. As of today, 12 different Digital Repositories hosting more than 60 heterogeneous dataset series are federated in GENESI-DR. Series include satellite data, in situ data, images acquired by airborne sensors, digital elevation models and model outputs. ESA has started providing access to: Category-1 data systematically available on Internet; level 3 data (e.g., GlobCover map, MERIS Global Vegetation Index); ASAR products available in ESA Virtual Archive and related to the Supersites initiatives. In all cases, existing data policies and security constraints are fully respected. GENESI-DR also gives access to Grid and Cloud computing resources allowing authorized users to run a number of different processing services on the available data. The GENESI-DR operational platform is currently being validated against several applications from different domains, such as: automatic orthorectification of SPOT data; SAR Interferometry; GlobModel results visualization and verification by comparison with satellite observations; ozone estimation from ERS-GOME products and comparison with in-situ LIDAR measures; access to ocean-related heterogeneous data and on-the-fly generated products. The project is adopting, ISO 19115, ISO 19139 and OGC standards for geospatial metadata discovery and processing, is compliant with the basis of INSPIRE Implementing Rules for Metadata and Discovery, and uses the OpenSearch protocol with Geo extensions for data and services discovery. OpenSearch is now considered by OGC a mass-market standard to provide machine accessible search interface to data repositories. GENESI-DR is gaining momentum in the Earth Science community thanks to the active participation to the GEO task force "Data Integration and Analysis Systems" and to the several collaborations with EC projects. It is now extending international cooperation agreements specifically with the NASA (Goddard Earth Sciences Data Information Services), with CEODE (the Center of Earth Observation for Digital Earth of Beijing), with the APN (Asia-Pacific Network), with University of Tokyo (Japanese GeoGrid and Data Integration and Analysis System).

The value of international health experience for doctors from developed nations is well recognised. Provisions have been made for medical staff in the United Kingdom to embark on work experiences abroad during their careers in the National Health Service. The London Deanery and Africa Health Placements provide an Out of Programme Experience for British General Practice trainee doctors wanting to work for a year in rural hospitals in South Africa. A qualitative study was conducted among fifteen British General Practice trainees who participated in the programme. The research aim was to understand the perceived benefit and value of their experience and their opinions about the structure of the programme. The data was analysed using thematic analysis. Their experience provided an accelerated year of learning and development that contributed to their professional and personal development. In addition to their general development, their improved ability to work in resource limited settings, enhancement of soft skills, a greater appreciation for the National Health Service and a better understanding of working within foreign health care systems were important gains. The timing of the experience, the security of re-employment on their return, assistance with administrative requirements of destination countries and the opportunity to gain varied, hands-on experience were highly valued components of the Out of Programme Experience. The value and benefits derived from the doctors' experience in South Africa are discussed in relation to another evaluation of the Out of Programme Experience, as well as issues of transferability of skills and competencies and future impacts on career decisions. This study provides evidence to suggest programmes such as the OOPE have the potential to create substantial benefits for trainee doctors, both in terms of their medical skills and competencies and through the development of softer skills. This programme, through the supply of scarce skills, further benefits the host country and specifically the health facilities and communities served by these trainee doctors.

Being well-informed and knowledgeable about their illnesses would be a great advantage to children with epilepsy (CWE). Subsequently, an effective education programme which could secure interest and simultaneously improve their awareness, knowledge and attitudes (AKA) is essential in enhancing well-being and health outcomes. To describe the development of a new interactive animated epilepsy education programme (IAEEP) for children and to assess its feasibility, acceptability and practicality. The IAEEP was developed by an interdisciplinary group of neurologist, paediatrician, pharmacist, biomedical scientist and educators which was based on two established epilepsy education programmes: the educational programme for patients with epilepsy and their relatives (MOSES) and the modular educational program for children with epilepsy and their parents (FAMOSES). CWE from paediatric department of three general hospitals in Terengganu were initially introduced to the IAEEP and were requested to complete an evaluation form assessing its feasibility, acceptability and practicality. Descriptive statistics were employed for data analyses (SPSS 20.0). Sixteen CWE (median age=13.0; male=56.2%; Malay=81.2%; secondary school=56.2%) and their corresponding parents were recruited. Each CWE owned at least a computer/notebook/tablet (100%). The cost of distribution of IAEEP (in compact disc form) among CWE was estimated at about MYR 17.99/USD 5.90 per CWE. The average time required to interact with the programme was 22.8 minutes (SD=3.3, range 18-28 minutes). The programme was 100% acceptable and received full support from both CWE and their parents (100%). The favourable findings from this study add to the growing evidence suggesting that investment in interactive and animated education programme would be both feasible, well-received by patients and could be a potentially valuable approach to increase access and effectiveness of epilepsy care especially among CWE.

There is a lack of nurse specialists in many paediatric hospitals in Sweden. This lack of competence is devastating for childhood cancer care because it is a highly specialised area that demands specialist knowledge. Continuing education of nurses is important to develop nursing practice and also to retain them. The aim of this study was to evaluate a Swedish national educational programme in paediatric oncology nursing. The nurses who participated came from all of the six paediatric oncology centres as well as from general paediatric wards. At the time of the evaluation, three groups of registered nurses (n=66) had completed this 2year, part-time educational programme. A study specific questionnaire, including closed and open-ended questions was sent to the 66 nurses and 54 questionnaires were returned. Answers were analysed using descriptive statistics and qualitative content analysis. The results show that almost all the nurses (93%) stayed in paediatric care after the programme. Furthermore, 31% had a position in management or as a consultant nurse after the programme. The vast majority of the nurses (98%) stated that the programme had made them more secure in their work. The nurses were equipped, through education, for paediatric oncology care which included: knowledge generating new knowledge; confidence and authority; national networks and resources. They felt increased confidence in their roles as paediatric oncology nurses as well as authority in their encounters with families and in discussions with co-workers. New networks and resources were appreciated and used in their daily work in paediatric oncology. The programme was of importance to the career of the individual nurse and also to the quality of care given to families in paediatric oncology. The national educational programme for nurses in Paediatric Oncology Care meets the needs of the highly specialised care. Copyright © 2015 Elsevier Ltd. All rights reserved.

To address the challenges of effective data handling faced by Small and Medium Sized Enterprises (SMEs) a cloud-based infrastructure for accessing and processing of Earth Observation(EO)-data has been developed within the project APPS4GMES(www.apps4gmes.de). To gain homogenous multi mission data access an Input Data Portal (IDP) been implemented on this infrastructure. The IDP consists of an Open Geospatial Consortium (OGC) conformant catalogue, a consolidation module for format conversion and an OGC-conformant ordering framework. Metadata of various EO-sources and with different standards is harvested and transferred to an OGC conformant Earth Observation Product standard and inserted into the catalogue by a Metadata Harvester. The IDP can be accessed for search and ordering of the harvested datasets by the services implemented on the cloud infrastructure. Different land-surface services have been realised by the project partners, using the implemented IDP and cloud infrastructure. Results of these are customer ready products, as well as pre-products (e.g. atmospheric corrected EO data), serving as a basis for other services. Within the IDP an automated access to ESA's Sentinel-1 Scientific Data Hub has been implemented. Searching and downloading of the SAR data can be performed in an automated way. With the implementation of the Sentinel-1 Toolbox and own software, for processing of the datasets for further use, for example for Vista's snow monitoring, delivering input for the flood forecast services, can also be performed in an automated way. For performance tests of the cloud environment a sophisticated model based atmospheric correction and pre-classification service has been implemented. Tests conducted an automated synchronised processing of one entire Landsat 8 (LS-8) coverage for Germany and performance comparisons to standard desktop systems. Results of these tests, showing a performance improvement by the factor of six, proved the high flexibility and computing power of the cloud environment. To make full use of the cloud capabilities a possibility for automated upscaling of the hardware resources has been implemented. Together with the IDP infrastructure fast and automated processing of various satellite sources to deliver market ready products can be realised, thus increasing customer needs and numbers can be satisfied without loss of accuracy and quality.

2015-04-01

IAGOS, In-service Aircraft for a Global Observing System, has installed instrumentation on a growing fleet of commercial airliners in order to continuously monitor atmospheric composition around the globe. IAGOS is providing accurate in situ observations of greenhouse gases (GHGs), reactive gases, aerosols, and cloud particles at high spatial resolution in the free atmosphere, thereby covering the essential climate variables (ECVs) for atmospheric composition as designated by the GCOS programme (Implementation Plan for the Global Observing System for Climate in Support of the UNFCCC, 2010). The greenhouse gas measurements made by IAGOS will be submitted to the WMO/GAW World Data Centre for Greenhouse Gases (WDCGG). Within the EU FP7 project IGAS (IAGOS for the GMES Atmospheric Service), the links between this new data stream and scientific users, including the Copernicus Atmosphere Monitoring Service, are being improved. This includes the provision of measurements in both near-real-time and delayed mode, and improved accessibility to the data through linkages to the databases of both the German Aerospace Centre (DLR) flight campaign archive and the Copernicus data archive. Work has been undertaken to investigate the use of the near-real-time profile measurements in order to correct bias in satellite measurements assimilated by the Copernicus Atmosphere Monitoring Service. Documentation of the QA/QC procedures and measurement techniques for each instrument have been formalized and reviewed by external experts, to provide users with a measurement traceable to WMO standards. The representativeness of the measurements has been assessed, to better interpret results in polluted regions and near the tropopause. The potential impact of the GHG measurements on regional scale flux inversions has been quantified, which is relevant for ICOS (Integrated Carbon Observing System). Finally, tools have been developed to use the measurements for validation of satellite column measurements, including collocation with satellite soundings, extension of the profiles to the full column, and convolution with the relevant averaging kernel. This presentation provides an overview of the activities undertaken in order to facilitate the use of the measurements provided by the IAGOS infrastructure.

The European Union Joint Procurement Agreement for cross-border health threats: what is the potential for this new mechanism of health system collaboration?

PubMed

Azzopardi-Muscat, Natasha; Schroder-Bäck, Peter; Brand, Helmut

2017-01-01

The Joint Procurement Agreement (JPA) is an innovative instrument for multi-country procurement of medical countermeasures against cross-border health threats. This paper aims to assess its potential performance. A literature review was conducted to identify key features of successful joint procurement programmes. Documentary analysis and a key informants' interview were carried out to analyse the European Union (EU) JPA. Ownership, equity, transparency, stable central financing, standardisation, flexibility and gradual development were identified as important prerequisites for successful establishment of multi-country joint procurement programmes in the literature while security of supply, favourable prices, reduction of operational costs and administrative burden and creation of professional expert networks were identified as desirable outcomes. The EU JPA appears to fulfil the criteria of ownership, transparency, equity, flexibility and gradual development. Standardisation is only partly fulfilled and central EU level financing is not provided. Security of supply is an important outcome for all EU Member States (MS). Price savings, reduction in administrative burden and creation of professional networks may be particularly attractive for the smaller MS. The JPA has the potential to increase health system collaboration and efficiency at EU level provided that the incentives for sustained commitment of larger MS are sufficiently attractive.

The economics of optimal health and productivity in the commercial dairy.

PubMed

Galligan, D T

1999-08-01

Dairy production practices are changing; in order to remain viable, producers must optimise the health and productivity of dairy herds in economic terms. Health care is important in economic terms because disease can substantially reduce the productivity of individual animals. Preventive disease control programmes can thus result in economic gains for the dairy producer. The author describes new approaches to preventing postpartum diseases and dealing with fertility problems which can result from these diseases. Other aspects of dairy production are also changing, employing new technologies where these are judged to be profitable. Innovations include: the use of bovine somatotropin; systematic breeding/culling programmes; new mathematical modelling techniques to determine optimum feed composition and to define optimal growth levels for accelerated heifer-rearing programmes; the use of computers to collect, store and analyse data on animal production and health; and semen selection programmes. Increasing awareness of bio-security is also vital, not least because of the large investment present in dairy herds. Whatever practices are employed, they must offer economic returns to producers that compete with alternative uses of capital. Optimal levels of disease control must be determined for a particular production situation, taking into account not only the economic health of the producer, but also the well-being of the animals.

The safe implementation of a prison-based methadone maintenance programme: 7 year time-series analysis of primary care prescribing data

PubMed Central

2014-01-01

Background Internationally there is policy support for the introduction of methadone maintenance programmes into prison settings. Increasingly GPs are encouraged to undertake this work although concerns remain regarding the safety of such programmes. This study sought to evaluate the impact and safety of the introduction of a general practitioner with a special interest (GPsi) in substance misuse led methadone prescribing service into a UK prison between 2003 and 2010. Methods Time series analysis of secondary prescribing data pertaining to opiate maintenance therapies, opiate detoxification therapies and opiate related deaths for the time period 2003 to 2010. Results Results show that following introduction of a GPsi in substance misuse there was a statistically significant increase in both methadone maintenance and detoxification treatments. Over time the rate of methadone maintenance prescribing plateaued with a corresponding decrease in the rate of methadone detoxification prescribing. There were no methadone related deaths in prison over the study period. Conclusion The phased introduction of opiate replacement therapies into a busy remand prison did not result in any deaths within the prison for which opiate replacement was identified as the cause. GPsi led opiate prescribing programmes can be introduced safely into secure environments. PMID:24712316

RIES - Rijnland Internet Election System: A Cursory Study of Published Source Code

NASA Astrophysics Data System (ADS)

Gonggrijp, Rop; Hengeveld, Willem-Jan; Hotting, Eelco; Schmidt, Sebastian; Weidemann, Frederik

The Rijnland Internet Election System (RIES) is a system designed for voting in public elections over the internet. A rather cursory scan of the source code to RIES showed a significant lack of security-awareness among the programmers which - among other things - appears to have left RIES vulnerable to near-trivial attacks. If it had not been for independent studies finding problems, RIES would have been used in the 2008 Water Board elections, possibly handling a million votes or more. While RIES was more extensively studied to find cryptographic shortcomings, our work shows that more down-to-earth secure design practices can be at least as important, and the aspects need to be examined much sooner than right before an election.

To describe the Nutrition Improvement Programme for Rural Compulsory Education Students (NIPRCES) in China and to share the experiences of developing and implementing nationwide school meal programmes with other countries. The article is based on a literature review of technical documents and reports of NIPRCES and relevant national legislation, technical reports and studies on school nutrition, minutes of meetings and national conferences, and official documents of the National Office of Student Nutrition and the Chinese Center for Disease Control and Prevention. People's Republic of China. Published papers, national policies, legislation and unpublished official documents. A total of 23 million rural compulsory education students were covered by NIPRCES. In the development and implementation process of NIPRCES, fifteen ministries and national committees were involved and an efficient collaborative mechanism was established. All NIPRCES-covered schools were required to serve meals on a daily basis. By the end of June 2012, the proportions of students choosing 'school feeding', 'food package' and 'family feeding' modes were respectively 64.0 %, 32.0 % and 4.0 %. The central government subsidized school meals annually by more than $US 2.5 billion and invested $US 4.8 billion on school kitchens to support this programme. The NIPRCES is a significant movement of governmental nutritional intervention in China. Food safety, financial security, decentralization and other potential concerns should be considered and lessons can be learned from other countries. Further relevant research and a nationwide monitoring and evaluation programme are needed.

Due to limited progress towards reducing mortality and malnutrition among children <5 years of age, an alliance of international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel,' starting with a situational analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of this analysis are to compile, analyse, and interpret available information on infant and child feeding and the nutrition situation of children <2 years of age in Niger, as one of the six targeted countries. Between August and November 2008, key informants responsible for conducting IYCN-related activities in Niger were interviewed, and 90 documents were examined on: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of HIV, management of acute malnutrition, food security, and hygienic practices. The results reported are limited by the availability of documents for review. Mortality rates are on track to reaching the Millennium Development Goal to reduce mortality among young children by two-thirds by 2015, but there has been no change in undernutrition, and total mortality rates are still high among young children. Nearly all of the key IYCN topics were addressed, specifically or generally, in national policy documents, training materials, and programmes. A national nutrition council meets regularly to coordinate programme activities nationally. Many of the IYCN-related programmes are intended for national coverage, but few reach this coverage. Monitoring and impact evaluations were conducted on some programmes, but few of these reported on whether the specific IYCN components of the programme were implemented as designed or compared outcomes with non-intervention sites. Human resources have been identified as inadequate to fully carry out nutrition programmes in Niger. Due to these limitations, we could not confirm whether the lack of progress in reducing malnutrition was due to ineffective or inadequately implemented programmes, though both of these were likely contributors. The policy framework is well established for the promotion of optimal IYCN practices, but greater resources and capacity building are needed to: (i) increase human capacities to carry out nutrition programmes; (ii) expand and track the implementation of evidence-based programmes nationally; (iii) improve and carry out monitoring and evaluation that identify effective and ineffective programmes; and (iv) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

All-optical central-frequency-programmable and bandwidth-tailorable radar

2016-01-01

Radar has been widely used for military, security, and rescue purposes, and modern radar should be reconfigurable at multi-bands and have programmable central frequencies and considerable bandwidth agility. Microwave photonics or photonics-assisted radio-frequency technology is a unique solution to providing such capabilities. Here, we demonstrate an all-optical central-frequency-programmable and bandwidth-tailorable radar architecture that provides a coherent system and utilizes one mode-locked laser for both signal generation and reception. Heterodyning of two individually filtered optical pulses that are pre-chirped via wavelength-to-time mapping generates a wideband linearly chirped radar signal. The working bands can be flexibly tailored with the desired bandwidth at a user-preferred carrier frequency. Radar echoes are first modulated onto the pre-chirped optical pulse, which is also used for signal generation, and then stretched in time or compressed in frequency several fold based on the time-stretch principle. Thus, digitization is facilitated without loss of detection ability. We believe that our results demonstrate an innovative radar architecture with an ultra-high-range resolution. PMID:26795596

The Jason-CS/Sentinel-6 programme will consist of 2 spacecraft and will be the latest in a series of ocean surface topography missions that will span nearly three decades. They follow the altimeters on-board TOPEX/Poseidon through to Jason-3 (expected March 2015). Jason-CS will continue to fulfil objectives of the reference series whilst introducing a major enhancement in capability providing the operational and science oceanographic community with the state of the art in terms of platform, measurement instrumentation design thus securing optimal operational and science data return. The programme is a part of the EC Copernicus initiative, whose objective is to support Europe's goals regarding sustainable development and global governance of the environment by providing timely and quality data, information, services and knowledge. The programme brings together: ESA for development, procurement & early orbit activities; EUMETSAT for mission management, ground segment, flight ops, contributing funding of the 1st satellite and participation in funding for the 2nd satellite; NOAA for US payload instruments, launcher, ground stations & operations; NASA for developing the US payload, launcher procurement and funding US science; EU for funding the operations and participation in funding (with EUMETSAT) for the 2nd satellite; CNES for mission expertise and provision of POD. The consortium plan to procure 2 satellites with the 1st planned for launch readiness in the 1st half of 2020 with the 2nd satellite 5 years later. The first major commitment to funding was given by the ESA member states that approved the programme in June 2014 and in addition the European Union funding is also secure. The design will be based on a platform derived from CryoSat-2 but adjusted to the specific requirements of the higher orbit. The principle payload instrument is a high precision Ku/C band radar altimeter with retrieval of geophysical parameters (surface elevation, wind speed and SWH) from the altimeter data require supporting measurements: a DORIS receiver for POD; The Climate Quality Advanced Microwave Radiometer (AMR-C) provided by JPL for high stability path delay correction. Orbit tracking data are also provided by GPS & LRA. An additional US GPS receiver, GNSS-RO, will be dedicated to radio-occultation measurements.

Prospective study of factors influencing conditional discharge from a forensic hospital: the DUNDRUM-3 programme completion and DUNDRUM-4 recovery structured professional judgement instruments and risk

PubMed Central

2013-01-01

Background We set out to examine whether structured professional judgement instruments DUNDRUM-3 programme completion (D-3) and DUNDRUM-4 recovery (D-4) scales along with measures of risk, mental state and global function could distinguish between those forensic patients detained in a secure forensic hospital (not guilty by reason of insanity or unfit to stand trial) who were subsequently discharged by a mental health review board. We also examined the interaction between these measures and risk, need for therapeutic security and eventual conditional discharge. Methods A naturalistic observational cohort study was carried out for 56 patients newly eligible for conditional discharge. Patients were rated using the D-3, D-4 and other scales including HCR-20, S-RAMM, START, SAPROF, PANSS and GAF and then observed over a period of twenty three months during which they were considered for conditional discharge by an independent Mental Health Review Board. Results The D-3 distinguished which patients were subsequently discharged by the Mental Health Review board (AUC = 0.902, p < 0.001) as did the D-4 (AUC = 0.848, p < 0.001). Item to outcome analysis showed each item of the D-3 and D-4 scales performed significantly better than random. The HCR-20 also distinguished those later discharged (AUC = 0.838, p < 0.001) as did the S-RAMM, START, SAPROF, PANSS and GAF. The D-3 and D-4 scores remained significantly lower (better) for those discharged even when corrected for the HCR-20 total score. Item to outcome analyses and logistic regression analysis showed that the strongest antecedents of discharge were the GAF and the DUNDRUM-3 programme completion scores. Conclusions Structured professional judgement instruments should improve the quality, consistency and transparency of clinical recommendations and decision making at mental health review boards. Further research is required to determine whether the DUNDRUM-3 programme completion and DUNDRUM-4 recovery instruments predict those who are or are not recalled or re-offend after conditional discharge.

Anger management programmes for offenders typically aim to improve the management of emotion associated with aggressive and antisocial behaviour. Such programmes have been quite extensively evaluated in prison and probation settings, but there is less published research in forensic mental health settings. This study aimed to evaluate anger management groups in a high-security hospital. Eighty-six patients were referred for a 20-session anger management intervention. Outcomes were self-reported experiences of anger and changes in institutionally documented incidents of aggression. Incident rates were retrospectively reviewed for all group graduates, where data were available, including a comparison group of graduates who acted as their own controls. Group graduates reported sustained reductions in feelings of anger and positive changes in their use of aggression in reaction to provocation. Some reduction in incidents of physical aggression was noted when group completers were compared with non-completers. Incidents of verbal aggression were observed to increase for graduates. There was also a trend towards improvement when treated men were compared with men on the waiting list. Our findings contribute to the growing evidence for anger management groups for aggressive men, although the low-base rate of incidents, typical of such a containing and therapeutic hospital setting, rendered the analysis of behavioural outcomes difficult. Anger management sessions for male forensic psychiatric patients can be effective in reducing incidents of physical aggression in response to provocation. Evaluation of treatments for anger is particularly difficult in secure and protective settings, where the aim is to keep incidents of actual physical aggression to a minimum. Further research of this kind is needed to test the value of self-reported reduction in angry feelings as an indicator of clinically useful progress. Copyright © 2013 John Wiley & Sons, Ltd.

The study was conducted in January 2012, six months after independence. Study subjects included eighty mothers of children aged 6–23 months in structured interviews and eight focus groups, each with six to ten participants, of mothers of children aged 6–23 months. Ninety-three per cent of households surveyed in Warrap and 100% of households in Northern Bahr el Ghazal states were severely food access insecure. Nearly all households (97?5%) surveyed in both states reported there were months in 2011 without enough food to eat. The majority of households (88%) reported sometimes or often going to bed hungry in the month preceding the study. A number of coping mechanisms were used when households did not have enough food, including reduced meal size, skipping meals, selling assets and engaging in some kind business in order to generate money to buy food. Given the highly volatile political, economic and humanitarian situation in South Sudan, the priorities of the international community are understandably focused on securing greater stability in South Sudan and preventing humanitarian needs from escalating significantly. There is a need, however, for simultaneous emphasis on food assistance and longer-term development strategies throughout South Sudan, particularly in areas of agriculture, livelihoods and food security.

‘Never heard of it’– Understanding the public’s lack of awareness of a new electronic patient record

Bratan, Tanja; Stramer, Katja; Greenhalgh, Trisha

2010-01-01

Abstract Background  The introduction of electronic patient records that are accessible by multiple providers raises security issues and requires informed consent – or at the very least, an opportunity to opt out. Introduction of the Summary Care Record (SCR) (a centrally stored electronic summary of a patient’s medical record) in pilot sites in the UK was associated with low awareness, despite an intensive public information programme that included letters, posters, leaflets, and road shows. Aim  To understand why the public information programme had limited impact and to learn lessons for future programmes. Methods  Linguistic and communications analysis of components of the programme, contextualized within a wider mixed‐method case study of the introduction of the SCR in pilot sites. Theoretical insights from linguistics and communication studies were applied. Results  The context of the SCR pilots and the linked information programme created inherent challenges which were partially but not fully overcome by the efforts of campaigners. Much effort was put into designing the content of a mail merge letter, but less attention was given to its novelty, linguistic style, and rhetorical appeal. Many recipients viewed this letter as junk mail or propaganda and discarded it unread. Other components of the information programme were characterized by low visibility, partly because only restricted areas were participating in the pilot. Relatively little use was made of interpersonal communication channels. Conclusion  Despite ethical and legal imperatives, informed consent for the introduction of shared electronic records may be difficult to achieve through public information campaigns. Success may be more likely if established principles of effective mass and interpersonal communication are applied. PMID:20579117

Targeted social protection in a pastoralist economy: case study from Kenya.

PubMed

Janzen, S A; Jensen, N D; Mude, A G

2016-11-01

Social protection programmes are designed to help vulnerable populations - including pastoralists - maintain a basic level of well-being, manage risk, and cope with negative shocks. Theory suggests that differential targeting according to poverty status can increase the reach and effectiveness of budgeted social protection programmes. Chronically poor households benefit most from social protection designed to help them meet their basic needs and make vital investments necessary to graduate from poverty. Vulnerable non-destitute households benefit from protection against costly temporary shocks, but do not necessarily need regular assistance. Welfare gains occur when a comprehensive social protection programme considers the needs of both types of households. The authors use evidence-based understanding of poverty dynamics in the pastoralist-based economy of northern Kenya's arid and semi-arid lands as a case study to discuss and compare the observed impacts of two different social protection schemes on heterogeneous pastoralist households: a targeted, unconditional, cash-transfer programme designed to support the poorest, and an index-based livestock insurance programme, which acts as a productive 'safety net' to help stem a descent into poverty and increase resilience. Both types of social protection scheme have been shown to decrease poverty, improve food security and protect child health. However, the behavioural response for asset accumulation varies with the type of protection and the household's unique situation. Poor households that receive cash transfers retain and accumulate assets quickly. Insured households, who are typically vulnerable yet not destitute, protect existing herds and invest more in the livestock they already own. The authors argue that differential targeting increases programme efficiency, and discuss Kenya's current approach to implementing differentially targeted social protection.

The promise of acceptance as an NGO security management approach.

Fast, Larissa; Freeman, Faith; O'Neill, Michael; Rowley, Elizabeth

This paper explores three questions related to acceptance as a security management approach. Acceptance draws upon relationships with community members, authorities, belligerents and other stakeholders to provide consent for the presence and activities of a non-governmental organisation (NGO), thereby reducing threats from these actors. Little is documented about how NGOs gain and maintain acceptance, how they assess and monitor the presence and degree of acceptance, or how they determine whether acceptance is effective in a particular context. Based on field research conducted in April 2011 in Kenya, South Sudan and Uganda, we address each of these three issues and argue that acceptance must be actively sought as both a programme and a security management strategy. In the paper we delineate elements common to all three contexts as well as missed opportunities, which identify areas that NGOs can and should address as part of an acceptance approach. © 2015 The Author(s).

Governance and Risk Management of Network and Information Security: The Role of Public Private Partnerships in Managing the Existing and Emerging Risks

NASA Astrophysics Data System (ADS)

Navare, Jyoti; Gemikonakli, Orhan

Globalisation and new technology has opened the gates to more security risks. As the strategic importance of communication networks and information increased, threats to the security and safety of communication infrastructures, as well as information stored in and/or transmitted increased significantly. The development of the self replicating programmes has become a nightmare for Internet users. Leading companies, strategic organisations were not immune to attacks; they were also "hacked" and overtaken by intruders. Incidents of recent years have also shown that national/regional crisis may also trigger cyber attacks at large scale. Experts forecast that cyber wars are likely to take the stage as tension mounts between developed societies. New risks such as cyber-attacks, network terrorism and disintegration of traditional infrastructures has somewhat blurred the boundaries of operation and control. This paper seeks to consider the risk management and governance and looking more specifically at implications for emerging economies.

Children of psychiatrically ill parents up to now have hardly been perceived as a risk group. In order to prevent these children form becoming psychiatrically ill the practice for art-therapy and psychotherapy and the social psychiatric service of the city of Hilden have developed a programme for parents having children under 18 years of age in which at least one parent suffers from endogenous psychosis or severe personality disorder. The two initiators of the KIPKEL project describe the experiences they had during the preparatory phase and while securing the financial basis and building up solid structures of cooperation. The conceptual basis of the project and problems of practical realization are presented. Finally an example of a family who participated in the programme is given. It illustrates the complex arrangement of interpersonal relationship and the course of the carework.

The burden of infectious diseases in livestock and other animals continues to be a major constraint to sustained agricultural development, food security, and participation of developing and in-transition countries in the economic benefits of international trade in livestock commodities. Targeted measures must be instituted in those countries to reduce the occurrence of infectious diseases. Quality veterinary vaccines used strategically can and should be part of government sanctioned-programmes. Vaccination campaigns must be part of comprehensive disease control programmes, which, in the case of transboundary animal diseases, require a regional approach if they are to be successful. This paper focuses on the salient transboundary animal diseases and examines current vaccine use, promising vaccine research, innovative technologies that can be applied in countries in some important developing regions of the world, and the role of public/private partnerships.

Situational analysis of infant and young child nutrition policies and programmatic activities in Burkina Faso.

Progress towards reducing mortality and malnutrition among children < 5 years of age has been less than needed to achieve related Millennium Development Goals. Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The objectives of the present paper are to compare relevant national policies, training materials, programmes, and monitoring and evaluation activities with internationally accepted IYCN recommendations. These findings are available to assist countries in identifying inconsistencies and filling gaps in current programming. Between August and November 2008, key informants responsible for conducting IYCN-related activities in Burkina Faso were interviewed, and 153 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, screening and treatment of acute malnutrition, prevention of mother-to-child transmission of HIV, food security and hygienic practices. National policy documents addressed nearly all of the key IYCN topics, specifically or generally. Formative research has identified some local barriers and beliefs related to general breastfeeding and complementary feeding practices, and other formative research addressed about half of the IYCN topics included in this review. However, there was little evidence that this formative research was being utilized in developing training materials and designing programme interventions. Nevertheless, the training materials that were reviewed do provide specific guidance for nearly all of the key IYCN topics. Although many of the IYCN programmes are intended for national coverage, we could only confirm with available reports that programme coverage extended to certain regions. Some programme monitoring and evaluation were conducted, but few of these provided information on whether the specific IYCN programme components were implemented as designed. Most surveys that were identified reported on general nutrition status indicators, but did not provide the detail necessary for programme impact evaluations. The policy framework is well established for optimal IYCN practices, but greater resources and capacity building are needed to: (i) conduct necessary research and adapt training materials and programme protocols to local needs; (ii) improve, carry out, and document monitoring and evaluation that highlight effective and ineffective programme components; and (iii) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

To determine the association between household food security and infant complementary feeding practices in rural Bangladesh. Prospective, cohort study using structured home interviews during pregnancy and 3 and 9 months after delivery. We used two indicators of household food security at 3-months' follow-up: maternal Food Composition Score (FCS), calculated via the World Food Programme method, and an HHFS index created from an eleven-item food security questionnaire. Infant feeding practices were characterized using WHO definitions. Two rural sub-districts of Kishoreganj, Bangladesh. Mother-child dyads (n 2073) who completed the 9-months' follow-up. Complementary feeding was initiated at age ≤4 months for 7 %, at 5-6 months for 49 % and at ≥7 months for 44 % of infants. Based on 24 h dietary recall, 98 % of infants were still breast-feeding at age 9 months, and 16 % received ≥4 food groups and ≥4 meals (minimally acceptable diet) in addition to breast milk. Mothers' diet was more diverse than infants'. The odds of receiving a minimally acceptable diet for infants living in most food-secure households were three times those for infants living in least food-secure households (adjusted OR=3·0; 95 % CI 2·1, 4·3). Socio-economic status, maternal age, literacy, parity and infant sex were not associated with infant diet. HHFS and maternal FCS were significant predictors of subsequent infant feeding practices. Nevertheless, even the more food-secure households had poor infant diet. Interventions aimed at improving infant nutritional status need to focus on both complementary food provision and education.

In a participatory approach to health and development interventions, defining and measuring community mobilisation is important, but it is challenging to do this effectively, especially at scale. A cross-sectional, participatory monitoring tool was administered in 2008-2009 and 2009-2010 across a representative sample of 25 community-based groups (CBGs) formed under the Avahan India AIDS Initiative, to assess their progress in mobilisation, and to inform efforts to strengthen the groups and make them sustainable. The survey used a weighted index to capture both qualitative and quantitative data in numeric form. The index permitted broad, as well as highly detailed, analysis of community mobilisation, relevant at the level of individual groups, as well as state-wide and across the whole programme. The survey demonstrated that leadership and programme management were the strongest areas among the CBGs, confirming the programme's investment in these areas. Discussion of the Round 1 results led to efforts to strengthen governance and democratic decision making in the groups, and progress was reflected in the Round 2 survey results. CBG engagement with state authorities to gain rights and entitlements and securing the long-term financial stability of groups remain a challenge. The survey has proven useful for informing the managers of programmes about what is happening on the ground, and it has opened spaces for discussion within community groups about the nature of leadership, decision making and their goals, which is leading to accelerated progress. The tool provided useful data to manage community mobilisation in Avahan.

Background: India has recently achieved the “Polio free status” by WHO with stringent efforts of the Health Ministry to control its spread. However, we should not forget the lessons learnt from the failure of National malaria eradication Programme and National Tuberculosis control Programme which creates a need to assess the probable barriers for the various National Health Programmes. The present article presents an overview of the Polio Eradication programme in India highlighting the lessons learnt from the past. Also, it evaluates the reality behind full participation of Pulse Polio Programme. Materials and Methods: The study results of a cross-sectional survey conducted with an aim to assess the probable reasons and barriers behind non compliance of Pulse Polio Programme among parents of children (1-5 yr of age) of Modinagar area have also been discussed. The survey instrument was a structured, 10 item, closed ended questionnaire. Statistical analysis used: Chi-square test was used to analyze the difference between proportions of individual responses for each question and multiple logistic regression was used to assess relation between socio demographic parameter and absence from Polio Ravivaar. Results: The study reveals a surprising 68% attendance of Pulse Polio programme which is far behind the desired goal. Most of the parents who did not attend polio ravivaar considered that there was no need for the repetition of Polio vaccine (76.9%) followed by their fear that the vaccine might get contaminated during transportation (74.5%). A significant positive association was found between older age group of the eligible children (4-5 yr, O.R.1.52), female gender, illiterate parents, distance of more than one km from residence to vaccination and lack of source of information (O.R. 1.47). Conclusion: Efforts should be done to investigate the probable reasons behind non compliance for various immunization programmes to analyse the current situation in detail and formulate appropriate programs for coming years so that the efforts so far don’t go in vain and we secure a healthy Polio free nation for our future generations.

2016-12-01

In this paper, we presented a novel approach of low energy consumption architecture of S-Box used in Advanced Encryption Standard (AES) algorithm using programmable second order reversible cellular automata (RCA 2 ). The architecture entails a low power implementation with minimal delay overhead and the performance of proposed RCA 2 based S-Box in terms of security is evaluated using the cryptographic properties such as nonlinearity, correlation immunity bias, strict avalanche criteria, entropy and also found that the proposed architecture is secure enough for cryptographic applications. Moreover, the proposed AES algorithm architecture simulation studies show that energy consumption of 68.726 nJ, power dissipation of 3.856 mW for 0.18- μm at 13.69 MHz and energy consumption of 29.408 nJ, power dissipation of 1.65 mW for 0.13- μm at 13.69 MHz. The proposed AES algorithm with RCA 2 based S-Box shows a reduction power consumption by 50 % and energy consumption by 5 % compared to best classical S-Box and composite field arithmetic based AES algorithm. Apart from that, it is also shown that RCA 2 based S-Boxes are dynamic in nature, invertible, low power dissipation compared to that of LUT based S-Box and hence suitable for Wireless Body Area Network (WBAN) applications.

Improving community development by linking agriculture, nutrition and education: design of a randomised trial of "home-grown" school feeding in Mali.

Providing food through schools has well documented effects in terms of the education, health and nutrition of school children. However, there is limited evidence in terms of the benefits of providing a reliable market for small-holder farmers through "home-grown" school feeding approaches. This study aims to evaluate the impact of school feeding programmes sourced from small-holder farmers on small-holder food security, as well as on school children's education, health and nutrition in Mali. In addition, this study will examine the links between social accountability and programme performance. This is a field experiment planned around the scale-up of the national school feeding programme, involving 116 primary schools in 58 communities in food insecure areas of Mali. The randomly assigned interventions are: 1) a school feeding programme group, including schools and villages where the standard government programme is implemented; 2) a "home-grown" school feeding and social accountability group, including schools and villages where the programme is implemented in addition to training of community based organisations and local government; and 3) the control group, including schools and household from villages where the intervention will be delayed by at least two years, preferably without informing schools and households. Primary outcomes include small-holder farmer income, school participation and learning, and community involvement in the programme. Other outcomes include nutritional status and diet-diversity. The evaluation will follow a mixed method approach, including household, school and village level surveys as well as focus group discussions with small-holder farmers, school children, parents and community members. The impact evaluation will be incorporated within the national monitoring and evaluation (M&E) system strengthening activities that are currently underway in Mali. Baselines surveys are planned for 2012. A monthly process monitoring visits, spot checks and quarterly reporting will be undertaken as part of the regular programme monitoring activities. Evaluation surveys are planned for 2014. National governments in sub-Saharan Africa have demonstrated strong leadership in the response to the recent food and financial crises by scaling-up school feeding programmes. "Home-grown" school feeding programmes have the potential to link the increased demand for school feeding goods and services to community-based stakeholders, including small-holder farmers and women's groups. Alongside assessing the more traditional benefits to school children, this evaluation will be the first to examine the impact of linking school food service provision to small-holder farmer income, as well as the link between community level engagement and programme performance.

2007-12-01

The Snow Water Equivalent (SWE) is an important component of the hydrologic balance of mountain basins and snow fed areas in general. The total cumulated snow water equivalent at the end of the accumulation season represents the water availability at melt. Here, a statistical methodology to estimate the Snow Water Equivalent, at April 1st, is developed coupling ground data (snow depth and snow density measurements) and MODIS images. The methodology is applied to the Mallero river basin (about 320 km²) located in the Central Alps, northern Italy, where are available 11 snow gauges and a lot of sparse snow density measurements. The application covers 7 years from 2001 to 2007. The analysis has identified some problems in the MODIS information due to the cloud cover and misclassification for orographic shadow. The study is performed in the framework of AWARE (A tool for monitoring and forecasting Available WAter REsource in mountain environment) EU-project, a STREP Project in the VI F.P., GMES Initiative.

Returns on vocational education over the life cycle: Between immediate labour market preparation and lifelong employability

Lavrijsen, Jeroen; Nicaise, Ides

2017-04-01

An important issue in the design of secondary-level education is the balance between conveying general and occupation-specific (vocational) skills. On the one hand, vocationally oriented programmes, providing occupation-specific skills with immediate labour market relevance, have repeatedly been shown to secure safe pathways into employment. On the other hand, these programmes tend to put less emphasis on developing general knowledge, skills and competencies, including numeracy and literacy, which are foundational to lifelong learning. Hence, when the needs of the labour market change, employees who opted for a vocational track when they were at secondary school risk being less flexible in adapting to such changes later in their career. The authors of this article examine whether this results in a trade-off between short-term gains and long-term losses by considering differences in the labour market careers of vocationally and generally educated respondents in the 2012 Programme for the International Assessment of Adult Competencies (PIAAC). Their results suggest that early labour market benefits of vocational specialisation decrease over time; the authors relate this to its lower ability to equip secondary school students - future employees - with skills for lifelong learning.

Capability Development among the Ultra-poor in Bangladesh: A Case Study

PubMed Central

2009-01-01

Microcredit is advocated as a development tool that has the potential to reduce poverty, empower participants, and improve health. Results of several studies have shown that the extreme poor, or the ultra-poor, often are unable to benefit from traditional microcredit programmes and can, as a result of taking a loan they cannot repay, sink deeper into economic and social poverty. This case study describes an intervention directed at enabling the ultra-poor rural populations to pull themselves out of poverty. The intervention integrates multiple components, including asset grants for income generation, skills training, a time-bound monthly stipend for subsistence, social development and mobilization of local elite, and health support. Results of an evaluation showed that, after 18 months, the programme positively impacted livelihood, economic, social and health status to the extent that 63% of households (n=5,000) maintained asset growth and joined (or intended to join) a regular microcredit programme. Impacts included improved income, improved food security, and improved health knowledge and behaviour. Applying a social exclusion framework to the intervention helps identify the different dynamic forces that can exclude or include the ultra-poor in Bangladesh in development interventions such as microcredit.

[Medical ethics in prison medicine].

PubMed

Bernheim, J

1980-11-01

A series of situations and decisions involving medical ethics in a prison medical service are discussed. The doctor's independence is considered in relation to his contract with administrative authorities. In contrast with most private doctor-patient relationships, there is usually no possibility for prisoners to choose their doctor and vice-versa. Freedom of consent on the part of the patient may also imply a right to no-treatment. Medical care in prison is not easy to delineate, also because patients often try to involve the doctor in non-medical demands. A prison doctor should avoid taking part in decisions which ought to be made by the judiciary or by administrative authorities. Programmes involving preventive medicine and sociotherapy imply collaboration between therapeutic and security staff. The continuous interplay and readjustment between powers based on public authority, on the rights of each individual prisoner and on the medical programmes makes it possible for some sort of therapeutic freedom to exist in the prison.

Monitoring landslide-induced deformation with TerraSAR-X Persistent Scatterer Interferometry (PSI): Gimigliano case study in Calabria Region (Italy)

NASA Astrophysics Data System (ADS)

Bianchini, S.; Cigna, F.; Del Ventisette, C.; Moretti, S.; Casagli, N.

2012-04-01

Landslide phenomena represent a major geological hazard worldwide, threatening human lives and settlements, especially in urban areas where the potential socio-economic losses and damages are stronger because of the higher value of the element at risk exposure and vulnerability. The impact of these natural disasters in highly populated and vulnerable areas can be reduced or prevented by performing a proper detection of such ground movements, in order to support an appropriate urban planning. Mapping and monitoring of active landslides and vulnerable slopes can greatly benefit from radar satellite data analysis, due to the great cost-benefits ratio, non-invasiveness and high precision of remote sensing techniques. This work illustrates the potential of Persistent Scatterer Interferometry (PSI) using X-band SAR (Synthetic Aperture Radar) data for a detailed detection and characterization of landslide ground displacements at local scale. PSI analysis is a powerful tool for mapping and monitoring slow surface displacements, just particularly in built-up and urbanized areas where many radar benchmarks (the PS, Persistent Scatterers) are retrieved. We exploit X-band radar data acquired from the German satellite TerraSAR-X on Gimigliano site located in Calabria Region (Italy). The use of TerraSAR-X imagery significantly improves the level of detail of the analysis and extends the applicability of space-borne SAR interferometry to faster ground movements, due to higher spatial resolutions (up to 1 m), higher PS targets density and shorter repeat cycles (11 days) of X-band satellites with respect to the medium resolution SAR sensors, such as ERS1/2, ENVISAT and RADARSAT1/2. 27 SAR scenes were acquired over a 116.9 Km2 extended area from the satellite TerraSAR-X in Spotlight mode, along descending orbits, with a look angle of 34°, from November 2010 to October 2011. The images were processed by e-GEOS with the Persistent Scatterers Pairs (PSP) technique, providing the estimation of annual velocities of LOS (Line Of Sight) ground displacements and related deformation time series for the whole acquisition period. The methodology performed is based on the integration of recent radar PS data in X-band with historical SAR archives derived from ERS1/2 and ENVISAT data in C-band, and with geological and geomorphological evidences resulting from the existing auxiliary data (e.g. landslide databases, thematic maps and aerial orthophotos), finally validated with field checks and in situ observations in the study area. This operative procedure led to the detailed study of the spatial distribution and temporal evolution of ground movements phenomena in Gimigliano site. The outcomes of this work represent a valuable example of detection and characterization of landslide-induced phenomena identified in detail by PSI analysis in X-band at local scale. This approach showed that PSI technique has the potential to improve the quality and timeliness of landslide inventories and consequently help for the implementation of best strategies for risk mitigation and urban-environmental design. This work was carried out within the SAFER (Services and Applications For Emergency Response) project, funded by the European Commission within the 7th Framework Programme under the Global Monitoring for Environment and Security (EC GMES FP7) initiative.

Despite decades of research, software continues to have vulnerabilities. Successful exploitations of these vulnerabilities by attackers cost millions of dollars to businesses and individuals. Unfortunately, most effective defensive measures, such as patching and intrusion prevention systems, require an intimate knowledge of the vulnerabilities. Many systems for detecting attacks have been proposed. However, the analysis of the exploited vulnerabilities is left to security experts and programmers. Both the human effortinvolved and the slow analysis process are unfavorable for timely defensive measure to be deployed. The problem is exacerbated by zero-day attacks.

Being the third fastest-growing app category behind games and utilities, mHealth apps are changing the healthcare model, as medicine today involves the data they compile and analyse, information known as Big Data. However, the majority of apps are lacking in security when gathering and dealing with the information, which becomes a serious problem. This article presents a guide regarding security solution, intended to be of great use for developers of mHealth apps. In August 2015 current mobile health apps were sought out in virtual stores such as Android Google Play, Apple iTunes App Store etc., in order to classify them in terms of usefulness. After this search, the most widespread weaknesses in the field of security in the development of these mobile apps were examined, based on sources such as the "OWASP Mobile Security Project, the initiative recently launched by the Office of Civil Rights (OCR), and other articles of scientific interest. An informative, elemental guide has been created for the development of mHealth apps. It includes information about elements of security and its implementation on different levels for all types of mobile health apps based on the data that each app manipulates, the associated calculated risk as a result of the likelihood of occurrence and the threat level resulting from its vulnerabilities - high level (apps for monitoring, diagnosis, treatment and care) from 6 ≤ 9, medium level (calculator, localizer and alarm) from 3 ≤ 6 and low level (informative and educational apps) from 0 ≤ 3. The guide aims to guarantee and facilitate security measures in the development of mobile health applications by programmers unconnected to the ITC and professional health areas.

CLImate-induced changes on WAter and SECurity (CLIWASEC) was a cluster of three complementary EC-FP7 projects assessing climate-change impacts throughout the Mediterranean on: hydrological cycles (CLIMB - CLimate-Induced changes on the hydrology of Mediterranean Basins); water security (WASSERMed - Water Availability and Security in Southern EuRope and the Mediterranean) and human security connected with possible hydro-climatic conflicts (CLICO - CLImate change hydro-COnflicts and human security). The Nile delta case study was common between the projects. CLIWASEC created an integrated forum for modelling and monitoring to understand potential impacts across sectors. This paper summarises key results from an integrated assessment of potential challenges to water-related security issues, focusing on expected sea-level rise impacts by the middle of the century. We use this common focus to illustrate the added value of project clustering. CLIWASEC pursued multidisciplinary research by adopting a single research objective: sea-level rise related water security threats, resulting in a more holistic view of problems and potential solutions. In fragmenting research, policy-makers can fail to understand how multiple issues can materialize from one driver. By combining efforts, an integrated assessment of water security threats in the lower Nile is formulated, offering policy-makers a clearer picture of inter-related issues to society and environment. The main issues identified by each project (land subsidence, saline intrusion - CLIMB; water supply overexploitation, land loss - WASSERMed; employment and housing security - CLICO), are in fact related. Water overexploitation is exacerbating land subsidence and saline intrusion, impacting on employment and placing additional pressure on remaining agricultural land and the underdeveloped housing market. All these have wider implications for regional development. This richer understanding could be critical in making better policy decisions when attempting to mitigate climate and social change impacts. The CLIWASEC clustering offers an encouraging path for the new European Commission Horizon 2020 programme to follow. Copyright © 2014 Elsevier B.V. All rights reserved.

The Ebola virus disease outbreak in West Africa was unprecedented in both its scale and impact. Out of this human calamity has come renewed attention to global health security—its definition, meaning, and the practical implications for programmes and policy. For example, how does a government begin to strengthen its core public health capacities, as demanded by the International Health Regulations? What counts as a global health security concern? In the context of the governance of global health, including WHO reform, it will be important to distil lessons learned from the Ebola outbreak. The Lancet invited a group of respected global health practitioners to reflect on these lessons, to explore the idea of global health security, and to offer suggestions for next steps. Their contributions describe some of the major threats to individual and collective human health, as well as the values and recommendations that should be considered to counteract such threats in the future. Many different perspectives are proposed. Their common goal is a more sustainable and resilient society for human health and wellbeing. PMID:25987157

Objectives: We aimed to investigate the effectiveness of a day visit in changing attitudes towards a high-security forensic psychiatric hospital, with regard to the current recruitment difficulties in psychiatry. Methods: Broadmoor Hospital, a UK high-security psychiatric hospital, runs day visits for medical students, led by doctors. At the beginning and the end of the day students wrote their responses to the question, ‘What do you think of Broadmoor?’ Attitudes and themes were identified, and their prevalence was analysed. Results: The responses of 296 students were initially analysed; however, 19 responses had to be excluded because they were illegible or incomplete. Before the visit, 15 responses were rated as positive, 169 neutral and 93 negative. After the visit, 205 responses were positive, 69 neutral and three negative. The themes that changed markedly following the visit were those indicating a change to favourable attitude. Conclusions: A single day visit was shown to be effective in altering the attitudes of medical students towards forensic psychiatry within a high-security psychiatric hospital. PMID:27683656

MERSEA, the European Gate to Ocean Data

Mersea ('Marine Environment and Security for the European Area'), a European project to manage the oceans, aims to develop by 2008 the GMES ocean component ('Global Monitoring for Environment and Security'), a system for operational monitoring and forecasting on global and regional scales of the ocean physics, bio-geochemistry and ecosystems. Mersea project started on April 1st, 2004. This ocean monitoring system is envisioned as an operational network that systematically acquires data and disseminates information to serve the needs of intermediate users and policy makers, in support of safe and efficient off-shore activities, environmental management, security, and sustainable use of marine resources. Three real-time data streams have been identified: remote sensed from satellites, in situ from ocean observing networks, and surface forcing fields from numerical weather prediction agencies. Mersea will ensure the availability of near real time and delayed mode products over the period 2004-2008, global and regional products optimised for supporting operational oceanography. Historical data sets for the last 15 years will also be prepared. Mersea is also the European center serving Godae goals ('Global Ocean Data Assimilation Experiment', 2003-2005). The timely delivery of high quality and reliable information to many user categories is essential for the success of such integrated project. There is consequently a large effort to coordinate all delivery actions giving special attention on the users' needs. This effort will cover many issues like product presentation, products and web services catalogue and how to deal for an interdisciplinary and integrated use. A first major difficulty is to reach at many levels product coherency and standardisation, which is needed to facilitate the visibility, understanding and exchange of the ocean observing data. A first task will therefore be to write a common unified framework guide, a kind of member chart, which will require from partners to 1- Apply or define standard for ocean products and associated information, 2- Harmonise the data exchange procedure (ie. rely on a decentralised but compatible system architecture for distribution on Internet), 3- Allow federation and cluster of individual data centers in order to facilitate the routine real-time exchange of high quality and appropriate environmental information, both in real-time and delayed mode (ie. set up a unique common ocean portal, an information management system for ocean products and services on Internet, which will allow the users to identify and access spatial or geographical information from a wide range of sources, from the local level to the global level, in real time and in an inter-operable way for a variety of uses). This presentation will comment on this member chart and requirements, and the ocean portal concept. We will review here also what has bee done for the precursor project Mersea Strand-1 and strengths and weaknesses raised (the participating ocean models FOAM- United Kingdom, Mercator- France , MFS Italy, Topaz- Norway , the unified framework, the distribution choice with Opendap e-technology, the manipulation and visualisation for education and public outreach or real-time complementary intercomparison expertise with a Live Access Server).

The Sentinel-1 & 3 mission are part of the Copernicus program, previously known as GMES (Global Monitoring for Environment and Security), whose overall objective is to support Europe's goals regarding sustainable development and global governance of the environment by providing timely and quality data, information, services and knowledge. This European Earth Observation program is led by the European Commission and the space infrastructure is developed under the European Space Agency leadership. Many services will be developed through the Copernicus program among different thematic areas. The climate change is one of this thematic area and the Sentinel-1 & 3 satellites will provide key space-based observations in this area. The Sentinel-1 mission is based on a constellation of 2 identical satellites each one embarking C-SAR Instrument and provides capability for continuous radar mapping of the Earth with enhanced revisit frequency, coverage, timeliness and reliability for operational services and applications requiring long time series. In particular, Sentinel 1 provides all-weather, day-and-night estimates of soil moisture, wind speed and direction, sea ice, continental ice sheets and glaciers. The Sentinel-3 mission will mainly be devoted to the provision of Ocean observation data in routine, long term (20 years of operations) and continuous fashion with a consistent quality and a very high level of availability. Among these data, very accurate surface temperatures and topography measurements will be provided and will constitute key indicators, once ingested in climate change models, for identifying climate drivers and expected climate impacts. The paper will briefly recall the satellite architectures, their main characteristics and performance. The inflight performance and key features of their images or data of the 3 satellites namely Sentinel 1A, 1B and 3A will be reviewed to demonstrate the quality and high scientific potential of the data as well as their availability to the user community. The short, medium and long term will be described. The first satellites are now in operation in orbit. Long-term plan foresees 2 add't recurrent satellites currently under prod, then a new gen in long term. Long term is crucial for climate change analysis & forecast, which is the goal of the Copernicus program.

This work presents the GIIDA (Gestione Integrata e Interoperativa dei Dati Ambientali del CNR) inter-departimental project of the Italian National Research Council (CNR). The project is an initiative of the Earth and Environment Department (Dipartimento Terra e Ambiente) of the CNR. GIIDA mission is "To implement the Spatial Information Infrastructure (SII) of CNR for Environmental and Earth Observation data". The project aims to design and develop a multidisciplinary cyber-infrastructure for the management, processing and evaluation of Earth and environmental data. This infrastructure will contribute to the Italian presence in international projects and initiatives, such as: INSPIRE, GMES, GEOSS and SEIS. The main GIIDA goals are: • Networking: To create a network of CNR Institutes for implementing a common information space and sharing spatial resources. • Observation: Re-engineering the environmental observation system of CNR • Modeling: Re-engineering the environmental modeling system del CNR • Processing: Re-engineering the environmental processing system del CNR • Mediation: To define mediation methods and instruments for implementing the international interoperability standards. The project started in July 2008 releasing a specification document of the GIIDA architecture for interoperability and security. Based on these documents, a Call for Proposals was issued in September 2008. GIIDA received 23 proposed pilots from 16 different Institutes belonging to five CNR Departments and from 15 non-CNR Institutions (e.g. three Italian regional administrations, three national research centers, four universities, some SMEs). These pilot were divided into thematic areas. In fact, GIIDA considers seven main thematic areas/domains: • Biodiversity; • Climate Changes; • Air Quality; • Soil and Water Quality; • Risks; • Infrastructures for Research and Public Administrations; • Sea and Marine resources Each of these thematic areas is covered by a Working Group which coordinates the activities and the achievements of the respective pilots. Working Groups are called to develop for each area: 1) a specific Web Portal; 2) a thematic catalog service; 3) a thematic thesaurus service; 4) a thematic Wiki; 5) standard access and view services for thematic resources -such as: datasets, models, and processing services; 6) a couple of significant use scenarios to be demonstrated.

The present study was designed to determine household food security status and factors associated with food insecurity among high-school students in Esfahan, Iran. Cross-sectional surveys. The present study was conducted in autumn 2008 in Esfahan, Iran. The samples were selected using systematic cluster sampling. Socio-economic questionnaires, food security questionnaires and FFQ were filled out during face-to-face interviews. In addition, data on participants' weights and heights were collected. A total of 580 students (261 boys and 319 girls) aged 14-17 years from forty high schools in Esfahan, Iran, were selected. The prevalence of household food insecurity according to the US Department of Agriculture food security questionnaire was 36.6 % (95 % CI 0.33, 0.40). Food insecurity was positively associated with number of members in the household (P < 0.05) and negatively associated with parental education level and job status and household economic status (P < 0.05). Moreover, students living in food-insecure households more frequently consumed bread, macaroni, potato and egg (P < 0.05), while they less frequently consumed rice, red meat, sausage and hamburger, poultry, fish, green vegetables, root and bulb (coloured) vegetables, melons, apples and oranges, milk and yoghurt (P < 0.05). Food insecurity was prevalent among households in Esfahan, Iran, and food security status was associated with socio-economic factors. Students who belonged to food-secure households more frequently consumed healthy foods (except sausage and hamburger), whereas those living in food-insecure households more frequently consumed cheap foods containing high energy per kilogram. The present study suggests that intervention programmes be designed and carried out.

As Ireland's national seabed mapping programme, INFOMAR1 (INtegrated mapping FOr the sustainable development of Ireland's MARine resource) enters its eleventh year it continues to provide pivotal seabed mapping data products, e.g. databases, charts and physical habitat maps to support Ireland's Integrated Marine Plan. The programme, jointly coordinated by the Geological Survey of Ireland and the Marine Institute, has gained a world class reputation for developing seabed mapping technologies, infrastructure and expertise. In the government's current Integrated Marine Plan, the programme's critical role in marine spatial planning enabling infrastructural development, research and education has been cited2. INFOMAR's free data policy supports a thriving maritime economy by promoting easy access to seabed mapping datasets that underpin; maritime safety, security and surveillance, governance, business development, research and technology innovation and infrastructure. The first hydrographic surveys of the national marine mapping programme mapped the extent of Ireland's deepest offshore area, whilst in recent years the focus has been to map the coastal and shallow areas. Targeted coastal areas include 26 bays and 3 priority areas for which specialised equipment, techniques and vessels are required. This talk will discuss how the INFOMAR programme has evolved to address the scientific and technological challenges of seabed mapping across a range of water depths; particularly the challenges associated with addressing inshore data gaps. It will describe how the data converts to bathymetric and geological maps detailing seabed characteristics and habitats. We will expand on how maps are: incorporated into collaborative marine projects such as EMODnet, commercialised to identify marine resources and used as marine decision support tools that drive policy and promote protection of the vastly under discovered marine area.

Developing the evidence base for health promotion can be challenging because interventions often have to target competing determinants of health, including social, structural, environmental and political determinants; all of which are difficult to measure and thus evaluate. Drawing on a case study of food insecurity, which refers to inadequate access to food due to financial constraints, we illustrate the challenges faced by community-based organizations in collecting data to form an evidence base for the development and evaluation of collective programmes aimed at addressing food insecurity. Interviews were conducted with members of a multi-stakeholder coalition (n = 22 interviewees; n = 10 organizations) who collectively work to address food insecurity in their community through a range of community-based programmes and services. Member organizations also provided a list of measures currently used to inform programme and service development and evaluation. Data were collected in a city in Southern Ontario, Canada between May and September 2015. Participants identified four barriers to collecting data: Organizational needs and philosophies; concerns surrounding clientele wellbeing and dignity; issues of feasibility; and restrictive requirements imposed by funding bodies. Participants also discussed their previous successes in collecting meaningful data for identifying impact. Our results point to the challenge of generating data suitable for developing and evaluating programmes aimed at broader determinants of health, while maintaining the primary goal of meeting clients' needs. Documenting change at intermediate- and macro-levels would provide evidence for the collective effectiveness of current programmes and services offered. However, appropriate resources need to be invested to allow for scientific evaluation. © The Author 2017. Published by Oxford University Press. All rights reserved.

In light of the decline in donor HIV funding, HIV programmes increasingly need to assess their available and potential resources and maximize their utilization. This article presents lessons learned related to how countries have addressed the sustainability of HIV programmes in a stakeholder-driven sustainability analysis. During HIV/AIDS Programme Sustainability Analysis Tool (HAPSAT) applications in six countries (Benin, Guyana, Kenya, Lesotho, Sierra Leone and South Sudan), stakeholders identified key sustainability challenges for their HIV responses. Possible policy approaches were prepared, and those related to prioritization and resource mobilization are analysed in this article. The need to prioritize evidence-based interventions and apply efficiency measures is being accepted by countries. Five of the six countries in this study requested that the HAPSAT team prepare 'prioritization' strategies. Countries recognize the need to prepare for an alternative to 'universal access by 2015', acknowledging that their capacity might be insufficient to reach such high-coverage levels by then. There is further acceptance of the importance of reaching the most-at-risk, marginalized populations, as seen, for example, in South Sudan and Sierra Leone. However, the pace at which resources are shifting towards these populations is slow. Finally, only two of the six countries, Kenya and Benin, chose to examine options for generating additional financial resources beyond donor funding. In Kenya, three non-donor sources were recommended, yet even if all were to be implemented, it would cover only 25% of the funding needed. Countries are increasingly willing to address the challenges of HIV programme sustainability, yet in different ways and with varying urgency. To secure achievements made to date and maximize future impact, countries would benefit from strengthening their strategic plans, operational plans and funding proposals with concrete timelines and responsibilities for addressing sustainability issues.

Occupational health in Brazil.

Bedrikow, B; Algranti, E; Buschinelli, J T; Morrone, L C

1997-01-01

Brazil is a recently industrialised country with marked contrasts in social and economic development. The availability of public/private services in its different regions also varies. Health indicators follow these trends. Occupational health is a vast new field, as in other developing countries. Occupational medicine is a required subject in graduation courses for physicians. Specialisation courses for university graduated professionals have more than 700 hours of lectures and train occupational health physicians, safety engineers and nursing staff. At the technical level, there are courses with up to 1300 hours for the training of safety inspectors. Until 1986 about 19,000 occupational health physicians, 18,000 safety engineers and 51,000 safety inspectors had been officially registered. Although in its infancy, postgraduation has attracted professionals at university level, through residence programmes as well as masters and doctors degrees, whereby at least a hundred good-quality research studies have been produced so far. Occupational health activities are controlled by law. Undertakings with higher risks and larger number of employees are required to hire specialised technical staff. In 1995 the Ministry of Labour demanded programmes of medical control of occupational health (PCMSO) for every worker as well as a programme of prevention of environmental hazards (PPRA). This was considered as a positive measure for the improvement of working conditions and health at work. Physicians specialising in occupational medicine are the professionals more often hired by the enterprises. Reference centres (CRSTs) for workers' health are connected to the State or City Health Secretariat primary health care units. They exist in more populated areas and are accepted by workers as the best way to accomplish the diagnosis of occupational diseases. There is important participation by the trade unions in the management of these reference centres. For 30 years now employers organisations have also kept specialised services for safety and occupational health. Although they are better equipped they are less well used by the workers than the CRSTs. At the federal level, activities concerned with occupational health are connected to three ministries: Labour, Health and Social Security. The Ministry of Labour enacts legislation on hygiene, safety and occupational medicine, performs inspections through its regional units and runs a number of research projects. The Ministry of Health provides medical care for workers injured or affected by occupational diseases and also has surveillance programmes for certain occupational diseases. The Ministry of Social Security provides rehabilitation and compensation for registered workers. In spite of a decrease in the number of accidents at work during the past 25 years, working conditions have not improved. Changes in the laws of social security in the 1970s discouraged registration and reporting of occupational injuries and diseases. In consequence death rates due to accidents increased. With the implementation of the CRSTs, the recorded incidence of occupational diseases has risen, not only because of improved diagnosis, but also because of stronger pressure from the unions and better organisation of public services and enterprises.

Implementation of a school-based social and emotional learning intervention: understanding diffusion processes within complex systems.

2015-07-01

Sporadic and inconsistent implementation remains a significant challenge for social and emotional learning (SEL) interventions. This may be partly explained by the dearth of flexible, causative models that capture the multifarious determinants of implementation practices within complex systems. This paper draws upon Rogers (2003) Diffusion of Innovations Theory to explain the adoption, implementation and discontinuance of a SEL intervention. A pragmatic, formative process evaluation was conducted in alignment with phase 1 of the UK Medical Research Council's framework for Developing and Evaluating Complex Interventions. Employing case-study methodology, qualitative data were generated with four socio-economically and academically contrasting secondary schools in Wales implementing the Student Assistance Programme. Semi-structured interviews were conducted with 15 programme stakeholders. Data suggested that variation in implementation activity could be largely attributed to four key intervention reinvention points, which contributed to the transformation of the programme as it interacted with contextual features and individual needs. These reinvention points comprise the following: intervention training, which captures the process through which adopters acquire knowledge about a programme and delivery expertise; intervention assessment, which reflects adopters' evaluation of an intervention in relation to contextual needs; intervention clarification, which comprises the cascading of knowledge through an organisation in order to secure support in delivery; and intervention responsibility, which refers to the process of assigning accountability for sustainable delivery. Taken together, these points identify opportunities to predict and intervene with potential implementation problems. Further research would benefit from exploring additional reinvention activity.

Household perceptions and subjective valuations of indoor residual spraying programmes to control malaria in northern Uganda.

Insecticide-based tools remain critical for controlling vector-borne diseases in Uganda. Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness. Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households. A survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray (IRS) programme. A discrete choice experiment was conducted within the survey, in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled, hypothetical choice sets. The data were analysed using conditional logit regression models to estimate respondents' willingness to accept (WTA) some amount of money compensation in lieu of foregone malaria risk reductions. Latent class models were used to analyse whether respondent characteristics predicted WTA. Average WTA is estimated at $8.94 annually for a 10 % reduction in malaria risk, and additional co-benefits of IRS were estimated to be worth on average $54-$56 (depending on insecticide type) per round of IRS. Significant heterogeneity is observed: Four in five household heads in northern Uganda have high valuations for IRS programmes, while the remaining 20 % experience costly side effects of IRS (valued at between $2 and $3 per round). Statistically significant predictors of belonging to the high-value group include respondent gender, mean age of household members, participation in previous IRS, basic knowledge of mosquito reproduction, and the number of mosquito nets owned. Proxies for household income and wealth are not found to be statistically significant predictors of WTA. This study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS. However, there is significant heterogeneity in terms of the perceived side effects (positive and negative). This has implications for sustaining public support for these programmes in the long-term.

In August 2012, a literature search with the aim of describing indicators on food and water security in an Arctic health context was initialized in collaboration between the Arctic Human Health Expert Group, SDWG/AHHEG and the AMAP (Arctic Monitoring and Assessment Programme within the Arctic Council) Human Health Assessment Group, AMAP/HHAG. In December 2012, workshop discussions were performed with representatives from both of these organizations, including 7 Arctic countries. The aim of this article is to describe the workshop discussions and the rational for the 12 indicators selected and the 9 rejected and to discuss the potential feasibility of these. Advantages and disadvantages of candidate indicators were listed. Informative value and costs for collecting were estimated separately on a 3-level scale: low, medium and high. Based on these reviews, the final selection of promoted and rejected indicators was performed and summarized in tables. Among 10 suggested indicators of food security, 6 were promoted: healthy weight, traditional food proportion in diet, monetary food costs, non-monetary food accessibility, food-borne diseases and food-related contaminants. Four were rejected: per-person dietary energy supply, food security modules, self-estimated food safety and healthy eating. Among 10 suggested indicators of water security, 6 were promoted: per-capita renewable water, accessibility of running water, waterborne diseases, drinking-water-related contaminants, authorized water quality assurance and water safety plans. Four were rejected: water consumption, types of water sources, periodic water shortages and household water costs.

Implantable electronics: emerging design issues and an ultra light-weight security solution.

2010-01-01

Implantable systems that monitor biological signals require increasingly complex digital signal processing (DSP) electronics for real-time in-situ analysis and compression of the recorded signals. While it is well-known that such signal processing hardware needs to be implemented under tight area and power constraints, new design requirements emerge with their increasing complexity. Use of nanoscale technology shows tremendous benefits in implementing these advanced circuits due to dramatic improvement in integration density and power dissipation per operation. However, it also brings in new challenges such as reliability and large idle power (due to higher leakage current). Besides, programmability of the device as well as security of the recorded information are rapidly becoming major design considerations of such systems. In this paper, we analyze the emerging issues associated with the design of the DSP unit in an implantable system. Next, we propose a novel ultra light-weight solution to address the information security issue. Unlike the conventional information security approaches like data encryption, which come at large area and power overhead and hence are not amenable for resource-constrained implantable systems, we propose a multilevel key-based scrambling algorithm, which exploits the nature of the biological signal to effectively obfuscate it. Analysis of the proposed algorithm in the context of neural signal processing and its hardware implementation shows that we can achieve high level of security with ∼ 13X lower power and ∼ 5X lower area overhead than conventional cryptographic solutions.

In August 2012, a literature search with the aim of describing indicators on food and water security in an Arctic health context was initialized in collaboration between the Arctic Human Health Expert Group, SDWG/AHHEG and the AMAP (Arctic Monitoring and Assessment Programme within the Arctic Council) Human Health Assessment Group, AMAP/HHAG. In December 2012, workshop discussions were performed with representatives from both of these organizations, including 7 Arctic countries. The aim of this article is to describe the workshop discussions and the rational for the 12 indicators selected and the 9 rejected and to discuss the potential feasibility of these. Advantages and disadvantages of candidate indicators were listed. Informative value and costs for collecting were estimated separately on a 3-level scale: low, medium and high. Based on these reviews, the final selection of promoted and rejected indicators was performed and summarized in tables. Among 10 suggested indicators of food security, 6 were promoted: healthy weight, traditional food proportion in diet, monetary food costs, non-monetary food accessibility, food-borne diseases and food-related contaminants. Four were rejected: per-person dietary energy supply, food security modules, self-estimated food safety and healthy eating. Among 10 suggested indicators of water security, 6 were promoted: per-capita renewable water, accessibility of running water, waterborne diseases, drinking-water-related contaminants, authorized water quality assurance and water safety plans. Four were rejected: water consumption, types of water sources, periodic water shortages and household water costs. PMID:23940840

The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) Plum Brook Station (PBS) Spacecraft Propulsion Research Facility, commonly referred to as B-2, is NASA s third largest thermal-vacuum facility with propellant systems capability. B-2 has completed a modernization effort of its facility legacy data, video and control systems infrastructure to accommodate modern integrated testing and Information Technology (IT) Security requirements. Integrated systems tests have been conducted to demonstrate the new data, video and control systems functionality and capability. Discrete analog signal conditioners have been replaced by new programmable, signal processing hardware that is integrated with the data system. This integration supports automated calibration and verification of the analog subsystem. Modern measurement systems analysis (MSA) tools are being developed to help verify system health and measurement integrity. Legacy hard wired digital data systems have been replaced by distributed Fibre Channel (FC) network connected digitizers where high speed sampling rates have increased to 256,000 samples per second. Several analog video cameras have been replaced by digital image and storage systems. Hard-wired analog control systems have been replaced by Programmable Logic Controllers (PLC), fiber optic networks (FON) infrastructure and human machine interface (HMI) operator screens. New modern IT Security procedures and schemes have been employed to control data access and process control flows. Due to the nature of testing possible at B-2, flexibility and configurability of systems has been central to the architecture during modernization.

Improving community development by linking agriculture, nutrition and education: design of a randomised trial of “home-grown” school feeding in Mali

PubMed Central

2013-01-01

Background Providing food through schools has well documented effects in terms of the education, health and nutrition of school children. However, there is limited evidence in terms of the benefits of providing a reliable market for small-holder farmers through “home-grown” school feeding approaches. This study aims to evaluate the impact of school feeding programmes sourced from small-holder farmers on small-holder food security, as well as on school children’s education, health and nutrition in Mali. In addition, this study will examine the links between social accountability and programme performance. Design This is a field experiment planned around the scale-up of the national school feeding programme, involving 116 primary schools in 58 communities in food insecure areas of Mali. The randomly assigned interventions are: 1) a school feeding programme group, including schools and villages where the standard government programme is implemented; 2) a “home-grown” school feeding and social accountability group, including schools and villages where the programme is implemented in addition to training of community based organisations and local government; and 3) the control group, including schools and household from villages where the intervention will be delayed by at least two years, preferably without informing schools and households. Primary outcomes include small-holder farmer income, school participation and learning, and community involvement in the programme. Other outcomes include nutritional status and diet-diversity. The evaluation will follow a mixed method approach, including household, school and village level surveys as well as focus group discussions with small-holder farmers, school children, parents and community members. The impact evaluation will be incorporated within the national monitoring and evaluation (M&E) system strengthening activities that are currently underway in Mali. Baselines surveys are planned for 2012. A monthly process monitoring visits, spot checks and quarterly reporting will be undertaken as part of the regular programme monitoring activities. Evaluation surveys are planned for 2014. Discussion National governments in sub-Saharan Africa have demonstrated strong leadership in the response to the recent food and financial crises by scaling-up school feeding programmes. “Home-grown” school feeding programmes have the potential to link the increased demand for school feeding goods and services to community-based stakeholders, including small-holder farmers and women’s groups. Alongside assessing the more traditional benefits to school children, this evaluation will be the first to examine the impact of linking school food service provision to small-holder farmer income, as well as the link between community level engagement and programme performance.

The secure transfer of information is an important problem in modern telecommunications. Quantum key distribution (QKD) provides a solution to this problem by using individual quantum systems to generate correlated bits between remote parties, that can be used to extract a secret key. QKD with D-dimensional quantum channels provides security advantages that grow with increasing D. However, the vast majority of QKD implementations has been restricted to two dimensions. Here we demonstrate the feasibility of using higher dimensions for real-world quantum cryptography by performing, for the first time, a fully automated QKD session based on the BB84 protocol with 16-dimensional quantum states. Information is encoded in the single-photon transverse momentum and the required states are dynamically generated with programmable spatial light modulators. Our setup paves the way for future developments in the field of experimental high-dimensional QKD.

The first passive millimetre wave (PMMW) imagery is presented from two proof-of-concept aperture synthesis demonstrators, developed to investigate the use of aperture synthesis for personnel security screening and all weather flying at 94 GHz, and satellite based earth observation at 183 GHz [1]. Emission from point noise sources and discharge tubes are used to examine the coherence on system baselines and to measure the point spread functions, making comparisons with theory. Image quality is examined using near field aperture synthesis and G-matrix calibration imaging algorithms. The radiometric sensitivity is measured using the emission from absorbers at elevated temperatures acting as extended sources and compared with theory. Capabilities of the latest Field Programmable Gate Arrays (FPGA) technologies for aperture synthesis PMMW imaging in all-weather and security screening applications are examined.

Internet application technologies, such as cloud computing and cloud storage, have increasingly changed people's lives. Websites contain vast amounts of personal privacy information. In order to protect this information, network security technologies, such as database protection and data encryption, attract many researchers. The most serious problems concerning web vulnerability are e-mail address and network database leakages. These leakages have many causes. For example, malicious users can steal database contents, taking advantage of mistakes made by programmers and administrators. In order to mitigate this type of abuse, a website information disclosure assessment system is proposed in this study. This system utilizes a series of technologies, such as web crawler algorithms, SQL injection attack detection, and web vulnerability mining, to assess a website's information disclosure. Thirty websites, randomly sampled from the top 50 world colleges, were used to collect leakage information. This testing showed the importance of increasing the security and privacy of website information for academic websites.

The National School Meals Programme (PNAE in Portuguese initials) is a supplementary program to education that aims to provide school meals for pupils across the school system enrolled in public and philanthropic schools of primary education, secondary education, youth education, adult education and comprehensive education. The principles of the program are the universality and the expansion of student services in order to meet the Organic Law on Food and Nutritional Security (LOSAN), as well as the Food Security and Nutrition System. The objective of this study is to discuss forms of PNAE management to ensure that the students' right to school meals. This study is a reflection on how the resources of school meals are being managed, be it with a centralized, decentralized, semi-centralized or outsourced model. We conclude that the knowledge of the different forms of managing federal resources for food for school communities allows for making an informed choice regarding implementation and enforcement of PNAE.

To evaluate the effect of a weight-gain restriction programme for obese pregnant women on sickness absence days and pregnancy benefit days during pregnancy and postpartum. A prospective, controlled intervention study. The Swedish Social Security Agency's records were utilized to compile sickness absence and pregnancy benefit information. Antenatal care clinics in the south-east of Sweden. One hundred fifty-five obese pregnant women who participated in a weight restriction program with weekly structured motivational and behavioural talks combined with aqua-aerobics during pregnancy. A total of 193 obese pregnant women with no intervention served as controls. Sickness absence benefits and pregnancy benefits expressed as a percentage. On average women in the intervention group had 76.68 total full days of sickness absence benefit compared with 53.09 days in the control group. Total full days of pregnancy benefits were 39.66% days and 41.41% for the intervention and control groups respectively. For the women who were on sick leave there were no differences between the groups in the amount of days taken. Given the complexity of factors that have an influence on sickness absence leave, it is possible that programmes that do not address the influence of social aspects and attitudes towards sickness absence have limited effect.

Adverse childhood experiences, including abuse, neglect and household instability, affect lifelong health and economic potential. The present study investigates how adverse childhood experiences are associated with food insecurity by exploring caregivers' perceptions of the impact of their childhood adversity on educational attainment, employment and mental health. Semi-structured audio-recorded in-person interviews that included (i) quantitative measures of maternal and child health, adverse childhood experiences (range: 0-10) and food security using the US Household Food Security Survey Module; and (ii) qualitative audio-recorded investigations of experiences with abuse, neglect, violence and hunger over participants' lifetimes. Households in Philadelphia, PA, USA. Thirty-one mothers of children <4 years old who reported low or very low household food security. Twenty-one caregivers (68 %) reported four or more adverse childhood experiences, and this severity was significantly associated with reports of very low food security (Fisher's exact P=0·021). Mothers reporting emotional and physical abuse were more likely to report very low food security (Fisher's exact P=0·032). Qualitatively, participants described the impact of childhood adverse experiences with emotional and physical abuse/neglect, and household substance abuse, on their emotional health, school performance and ability to maintain employment. In turn, these experiences negatively affected their ability to protect their children from food insecurity. The associations between mothers' adverse experiences in childhood and reports of current household food security should inspire researchers, advocates and policy makers to comprehensively address family hardship through greater attention to the emotional health of caregivers. Programmes meant to address nutritional deprivation and financial hardship should include trauma-informed approaches that integrate behavioural interventions.

Parent-infant psychotherapy (PIP) is a dyadic intervention that works with parent and infant together, with the aim of improving the parent-infant relationship and promoting infant attachment and optimal infant development. PIP aims to achieve this by targeting the mother's view of her infant, which may be affected by her own experiences, and linking them to her current relationship to her child, in order to improve the parent-infant relationship directly. 1. To assess the effectiveness of PIP in improving parental and infant mental health and the parent-infant relationship.2. To identify the programme components that appear to be associated with more effective outcomes and factors that modify intervention effectiveness (e.g. programme duration, programme focus). We searched the following electronic databases on 13 January 2014: Cochrane Central Register of Controlled Trials (CENTRAL, 2014, Issue 1), Ovid MEDLINE, EMBASE, CINAHL, PsycINFO, BIOSIS Citation Index, Science Citation Index, ERIC, and Sociological Abstracts. We also searched the metaRegister of Controlled Trials, checked reference lists, and contacted study authors and other experts. Two review authors assessed study eligibility independently. We included randomised controlled trials (RCT) and quasi-randomised controlled trials (quasi-RCT) that compared a PIP programme directed at parents with infants aged 24 months or less at study entry, with a control condition (i.e. waiting-list, no treatment or treatment-as-usual), and used at least one standardised measure of parental or infant functioning. We also included studies that only used a second treatment group. We adhered to the standard methodological procedures of The Cochrane Collaboration. We standardised the treatment effect for each outcome in each study by dividing the mean difference (MD) in post-intervention scores between the intervention and control groups by the pooled standard deviation. We presented standardised mean differences (SMDs) and 95% confidence intervals (CI) for continuous data, and risk ratios (RR) for dichotomous data. We undertook meta-analysis using a random-effects model. We included eight studies comprising 846 randomised participants, of which four studies involved comparisons of PIP with control groups only. Four studies involved comparisons with another treatment group (i.e. another PIP, video-interaction guidance, psychoeducation, counselling or cognitive behavioural therapy (CBT)), two of these studies included a control group in addition to an alternative treatment group. Samples included women with postpartum depression, anxious or insecure attachment, maltreated, and prison populations. We assessed potential bias (random sequence generation, allocation concealment, incomplete outcome data, selective reporting, blinding of participants and personnel, blinding of outcome assessment, and other bias). Four studies were at low risk of bias in four or more domains. Four studies were at high risk of bias for allocation concealment, and no study blinded participants or personnel to the intervention. Five studies did not provide adequate information for assessment of risk of bias in at least one domain (rated as unclear).Six studies contributed data to the PIP versus control comparisons producing 19 meta-analyses of outcomes measured at post-intervention or follow-up, or both, for the primary outcomes of parental depression (both dichotomous and continuous data); measures of parent-child interaction (i.e. maternal sensitivity, child involvement and parent engagement; infant attachment category (secure, avoidant, disorganised, resistant); attachment change (insecure to secure, stable secure, secure to insecure, stable insecure); infant behaviour and secondary outcomes (e.g. infant cognitive development). The results favoured neither PIP nor control for incidence of parental depression (RR 0.74, 95% CI 0.52 to 1.04, 3 studies, 278 participants, low quality evidence) or parent-reported levels of depression (SMD -0.22, 95% CI -0.46 to 0.02, 4 studies, 356 participants, low quality evidence). There were improvements favouring PIP in the proportion of infants securely attached at post-intervention (RR 8.93, 95% CI 1.25 to 63.70, 2 studies, 168 participants, very low quality evidence); a reduction in the number of infants with an avoidant attachment style at post-intervention (RR 0.48, 95% CI 0.24 to 0.95, 2 studies, 168 participants, low quality evidence); fewer infants with disorganised attachment at post-intervention (RR 0.32, 95% CI 0.17 to 0.58, 2 studies, 168 participants, low quality evidence); and an increase in the proportion of infants moving from insecure to secure attachment at post-intervention (RR 11.45, 95% CI 3.11 to 42.08, 2 studies, 168 participants, low quality evidence). There were no differences between PIP and control in any of the meta-analyses for the remaining primary outcomes (i.e. adverse effects), or secondary outcomes.Four studies contributed data at post-intervention or follow-up to the PIP versus alternative treatment analyses producing 15 meta-analyses measuring parent mental health (depression); parent-infant interaction (maternal sensitivity); infant attachment category (secure, avoidant, resistant, disorganised) and attachment change (insecure to secure, stable secure, secure to insecure, stable insecure); infant behaviour and infant cognitive development. None of the remaining meta-analyses of PIP versus alternative treatment for primary outcomes (i.e. adverse effects), or secondary outcomes showed differences in outcome or any adverse changes.We used the Grades of Recommendation, Assessment, Development and Evaluation Working Group (GRADE) approach to rate the overall quality of the evidence. For all comparisons, we rated the evidence as low or very low quality for parental depression and secure or disorganised infant attachment. Where we downgraded the evidence, it was because there was risk of bias in the study design or execution of the trial. The included studies also involved relatively few participants and wide CI values (imprecision), and, in some cases, we detected clinical and statistical heterogeneity (inconsistency). Lower quality evidence resulted in lower confidence in the estimate of effect for those outcomes. Although the findings of the current review suggest that PIP is a promising model in terms of improving infant attachment security in high-risk families, there were no significant differences compared with no treatment or treatment-as-usual for other parent-based or relationship-based outcomes, and no evidence that PIP is more effective than other methods of working with parents and infants. Further rigorous research is needed to establish the impact of PIP on potentially important mediating factors such as parental mental health, reflective functioning, and parent-infant interaction.

Rising food costs & global food security: key issues & relevance for India.

2013-09-01

Rising food costs can have major impact on vulnerable households, pushing those least able to cope further into poverty and hunger. On the other hand, provided appropriate policies and infrastructure are in place, higher agricultural prices can also raise farmers' incomes and rural wages, improve rural economies and stimulate investment for longer-term economic growth. High food prices since 2007 have had both short-term impacts and long-term consequences, both good and bad. This article reviews the evidence of how rising costs have affected global food security since the food price crisis of 2007-2008, and their impact on different categories of households and countries. In light of recent studies, we know more about how households, and countries, cope or not with food price shocks but a number of contentious issues remain. These include the adequacy of current estimates and the interpretation of national and household food and nutrition security indicators. India is a particularly important country in this regard, given the high number of food insecure, the relative weight of India in global estimates of food and nutrition insecurity, and the puzzles that remain concerning the country's reported declining per capita calorie consumption. Competing explanations for what is behind it are not in agreement, but these all point to the importance of policy and programme innovation and greater investment necessary to reach the achievable goal of food and nutrition security for all.

Global action to prevent war: a programme for government and grassroots efforts to stop war, genocide and other forms of deadly conflict.

Dean, J; Forsberg, R C; Mendlovitz, S

2000-01-01

At the end of history's bloodiest century and the outset of a new millennium, we have an opportunity to fulfil one of humanity's oldest dreams: making the world largely free of war. Global changes make this goal achievable. Nuclear weapons have shown the folly of war. For the first time, there is no war and no immediate prospect of war among the main military powers. For the first time, many proven measures to prevent armed conflict, distilled in the crucible of this century's wars, are available. If systematically applied, these measures can sharply decrease the frequency and violence of war, genocide, and other forms of deadly conflict. To seize the opportunity, nations should adopt a comprehensive programme to reduce conventional armaments and armed conflict. This programme will complement and strengthen efforts to eliminate nuclear arms. To assure its ongoing worldwide implementation, the conventional reduction programme should be placed in a treaty framework. We propose a four-phased process, with three treaties, each lasting five to ten years, to lay the groundwork for the fourth treaty, which will establish a permanent international security system. The main objectives of the treaties are to achieve: 1. A verified commitment to provide full transparency on conventional armed forces and military spending, not to increase forces during negotiations on arms reductions, and to increase the resources allocated to multilateral conflict prevention and peacekeeping. 2. Substantial worldwide cuts in national armed forces and military spending and further strengthening of United Nations and regional peacekeeping and peace-enforcement capabilities. 3. A trial of a watershed commitment by participating nations, including the major powers, not to deploy their armed forces beyond national borders except in a multilateral action under UN or regional auspices. 4. A permanent transfer to the UN and regional security organizations of the authority and capability for armed intervention to prevent or end war, accompanied by further substantial cuts in national armed forces and increases in UN and regional forces. This programme offers many valuable features: a global framework for conventional forces that parallels the nuclear Non-Proliferation Treaty; a verified no-increase commitment for national armed forces based on full data exchange; a commitment to undertake prescribed confidence-building measures, including limits on force activities and deployments; a commitment to a specified plan for increased funding of UN and regional peacekeeping capabilities; a commitment to strengthen international legal institutions; and after a trial period, a lasting commitment by each participant not to unilaterally deploy its armed forces beyond its borders, but instead to give the responsibility for peacekeeping and peace enforcement to international institutions. This programme of phased steps to reduce armed forces and strengthen peacekeeping institutions will make war rare. It will foster the spread of zones of peace like those in North America and Western Europe where, after centuries of violence, international and civil war have given way to the peaceful settlement of disputes.

The aim of this study was to describe the development of a sustainable community early psychosis programme created through an academic-community partnership in the United States to other parties interested in implementing early psychosis services founded upon evidence-based practices within community settings. The service was developed around a sustainable core of key components, founded upon evidence-based practice, with additional flexible elements that could be adapted to the needs of the individual commissioning county. This paper describes the ways in which funding was sourced and secured as well as the partnerships developed through this process. Successful development of the Prevention and Recovery from Early Psychosis (PREP) programme in San Francisco County, California. PREP clinicians have received extensive training in the evidence-based approaches that are available through the programme and treated 30 clients and their families in the first year of operation. Development of a sustainable community programme of this type in a non-universal health-care setting, which is historically seen as non-integrated, required extensive partnering with agencies familiar with local resources. Implementation of the community-academic partnership bridged the gap between research and practice with successful integration of fidelity practice at the community level. The community partners were effective in sourcing funding and allocating resources, while the academic side of the partnership provided training in evidence-based models and oversight of clinical implementation of the model. Stringent evaluation of the impact of the service is our next focus. © 2011 Blackwell Publishing Asia Pty Ltd.

The usage of cell phones has increased enormously; at present silence and security is the need of the hour in many places. This can be done by using cell phone jammer, which blocks all the signals. This paper describes the design of an enhanced technique for jamming the cell phone signals. Our main objective is to concentrate on a specific band of frequency, which makes communication possible, by jamming this frequency we block out the specific signal that are responsible for making the call. This method enables the jammer to be more precise and effective, so precise that it can focus on specific area and allowing the programmer to define the area. The major advancement will be that emergency services can be availed which is very crucial in case of any calamity, they are intelligent devices as they act only after they receive signals and also it has a lesser power consumption than existing models. This technique has infinite potentials and sure can this be modified to match all our imaginations.

The astrometric mission GAIA is a cornerstone mission of the European Space Agency, due for launch in the 2010 time frame. Requiring extremely demanding performance GAIA calls for the development of an unprecedented large focal plane featuring innovative technologies. For securing the very challenging GAIA development, a significant number of technology activities have been initiated by ESA through a competitive selection process. In this context, an industrial consortium led by EADS-Astrium (France) with e2v technologies (UK) as major subcontractor was selected for the GAIA CCD and Focal Plane Technology Demonstrators programme, which is by far the most significant and the most critical GAIA pre-development for all aspects: science performance, development schedule and cost. This programme has started since August 2002 and will end early 2005 prior to commencement of the GAIA Phase B. While the GAIA payload will host three instruments and related focal planes, the major mission objectives are assigned to the Astrometric (ASTRO) Focal Plane, which is the subject of this presentation.

[Public health stewardship and governance regarding the Colombian healthcare system, 2012-2013].

Analysing decision-making concerning public health issues regarding the Colombian healthcare system from a market economy-based approach. This study involved applying Glaser and Strauss's grounded theory in six Colombian cities during 2012: Bogotá, Barranquilla, Bucaramanga, Leticia, Medellin and Pasto. 120 individual interviews were conducted with professionals involved in decision-making, running public healthcare programmes and making policy within public and private institutions. Fourteen focus groups were held with community organisation leaders. The findings suggested national and municipal health authorities' weak stewardship and ineffective governance regarding public healthcare policy and programmes, related to a lack of staff trained in public health management issues. In turn, this was related to political parties' interference and private insurers' particular interests and the structural fragmentation of functions and actors within the health system, thereby limiting public health development. A new axiology is necessary for achieving effective governance (I.e. cooperation between Colombian Healthcare Social Security System actors) to overcome current incompetence and financial self-interest predominating within the Colombian healthcare system.

Antibiotic policies and the role of strategic hospital leadership.

PubMed

Masterson, R G

1999-12-01

Operational aspects, programme construction and implementation are all essential components of antimicrobial control but are not the direct remit of management and must rest with the professional provider. Hospital leaders can influence antibiotic control through the priority they give it. This must not be purely financially driven and must incorporate an awareness of issues surrounding patient care. Such attitudes should encompass the consequences of poor prescribing practices in both human and corporate terms. A leader's recognition of these elements can be expressed through securing resources in terms of both the human and hardware components. The best signalling of the status of this activity is through ensuring its inclusion in clinical governance and organisational Board reports. The goals for hospital leaders should be evidence of effective working practices and the execution of their own responsibilities by championing robust structures and procedures are in place. Potent hospital leadership delivered to the focus of antimicrobial control programmes is a major tool for their success.

Automated Teller Machine (ATM) is an electronic banking outlet that allows bank customers to complete a banking transactions without the aid of any bank official or teller. Several problems are associated with the use of ATM card such card cloning, card damaging, card expiring, cast skimming, cost of issuance and maintenance and accessing customer account by third parties. The aim of this project is to give a freedom to the user by changing the card to biometric security system to access the bank account using Advanced Encryption Standard (AES) algorithm. The project is implemented using Field Programmable Gate Array (FPGA) DE2-115 board with Cyclone IV device, fingerprint scanner, and Multi-Touch Liquid Crystal Display (LCD) Second Edition (MTL2) using Very High Speed Integrated Circuit Hardware (VHSIC) Description Language (VHDL). This project used 128-bits AES for recommend the device with the throughput around 19.016Gbps and utilized around 520 slices. This design offers a secure banking transaction with a low rea and high performance and very suited for restricted space environments for small amounts of RAM or ROM where either encryption or decryption is performed.

Privacy and information security are important for all healthcare services, including home-based services. We have designed and implemented a prototype technology platform for providing home-based healthcare services. It supports a personal electronic health diary and enables secure and reliable communication and interaction with peers and healthcare personnel. The platform runs on a small computer with a dedicated remote control. It is connected to the patient's TV and to a broadband Internet. The platform has been tested with home-based rehabilitation and education programs for chronic obstructive pulmonary disease and diabetes. As part of our work, a risk assessment of privacy and security aspects has been performed, to reveal actual risks and to ensure adequate information security in this technical platform. Risk assessment was performed in an iterative manner during the development process. Thus, security solutions have been incorporated into the design from an early stage instead of being included as an add-on to a nearly completed system. We have adapted existing risk management methods to our own environment, thus creating our own method. Our method conforms to ISO's standard for information security risk management. A total of approximately 50 threats and possible unwanted incidents were identified and analysed. Among the threats to the four information security aspects: confidentiality, integrity, availability, and quality; confidentiality threats were identified as most serious, with one threat given an unacceptable level of High risk. This is because health-related personal information is regarded as sensitive. Availability threats were analysed as low risk, as the aim of the home programmes is to provide education and rehabilitation services; not for use in acute situations or for continuous health monitoring. Most of the identified threats are applicable for healthcare services intended for patients or citizens in their own homes. Confidentiality risks in home are different from in a more controlled environment such as a hospital; and electronic equipment located in private homes and communicating via Internet, is more exposed to unauthorised access. By implementing the proposed measures, it has been possible to design a home-based service which ensures the necessary level of information security and privacy.

To examine whether the cross-sectional association between food insecurity and overweight/obesity varied according to birthplace and length of residence in the USA among California women. Using cross-sectional, population-based data from the California Women's Health Survey (CWHS) 2009-2012, we examined whether the association between food insecurity and overweight or obesity varied by birthplace-length of US residence. California, USA. Women (n 16 008) aged 18 years or older. Among US-born women, very low food security (prevalence ratio (PR)=1·21; 95 % CI 1·11, 1·31) and low food security (PR=1·19; 95 % CI 1·10, 1·28) were significantly associated with higher prevalence of overweight/obesity, after controlling for age, marital status, race/ethnicity, poverty and education. Among immigrant women who lived in the USA for 10 years or longer, very low food security was significantly associated with higher prevalence of overweight/obesity, after controlling for covariates (PR=1·16; 95 % CI 1·07, 1·27). Among immigrant women who had lived in the USA for less than 10 years, low and very low food security were not significantly associated with overweight/obesity, after controlling for covariates. Food insecurity may be an important pathway through which weight may increase with longer US residence among immigrant women. Public health programmes and policies should focus on increasing food security for all women, including immigrant women, as one strategy to reduce the prevalence of overweight/obesity.

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals (MDGs), so several international agencies joined to 'reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse, and interpret available information on infant and child feeding, and the nutrition and health situation of children <2 years of age in Mauritania as one of the six target countries (Burkina Faso, Chad, Mali, Mauritania, Niger, Senegal). These findings are available to assist countries in identifying inconsistencies and filling gaps in current programming. Between August and November of 2008, key informants responsible for conducting IYCN-related activities in Mauritania were interviewed, and 46 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of human immunodeficiency virus (HIV), management of acute malnutrition, food security, and hygienic practices. Mauritania is on track to reaching the MDG of halving undernutrition among children <5 years of age by 2015. National policy documents, training guides, and programmes address nearly all of the key IYCN topics, specifically or generally. Exceptions are the use of zinc supplements in diarrhoea treatment, prevention of zinc deficiency, and dietary guidelines for preventing mother-to-child transmission of HIV. Substantial infrastructure capacity building was also recently implemented in nutritionally high-risk regions, and increases were reported in exclusive breastfeeding rates among children <6 months. The recent National Behaviour Change Communication Strategy is intended to address the needs of adapting programme activities to local needs. Despite these noteworthy accomplishments, the prevalence of acute malnutrition remains high, mortality rates did not decrease as malnutrition rates decreased, the overall prevalence of desirable nutrition-related practices is low, and human resources are reportedly insufficient to carry out all nutrition-related programme activities. Very little nutrition research has been conducted in Mauritania, and key informants identified gaps in adapting international programmes to local needs. Monitoring and evaluation reports have not been rigorous enough to identify which programme activities were implemented as designed or whether programmes were effective at improving nutritional and health status of young children. Therefore, we could not confirm which programmes might have been responsible for the reported improvements, or if other population-wide changes contributed to these changes. The policy framework is supportive of optimal IYCN practices, but greater resources and capacity building are needed to (i) support activities to adapt training materials and programme protocols to fit local needs, (ii) expand and track the implementation of evidence-based programmes nationally, (iii) improve and carry out monitoring and evaluation that identify effective and ineffective programmes, and (iv) apply these findings in developing, disseminating, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

How does context influence performance of community health workers in low- and middle-income countries? Evidence from the literature.

Community health workers (CHWs) are increasingly recognized as an integral component of the health workforce needed to achieve public health goals in low- and middle-income countries (LMICs). Many factors intersect to influence CHW performance. A systematic review with a narrative analysis was conducted to identify contextual factors influencing performance of CHWs. We searched six databases for quantitative, qualitative, and mixed-methods studies that included CHWs working in promotional, preventive or curative primary health care services in LMICs. We differentiated CHW performance outcome measures at two levels: CHW level and end-user level. Ninety-four studies met the inclusion criteria and were double read to extract data relevant to the context of CHW programmes. Thematic coding was conducted and evidence on five main categories of contextual factors influencing CHW performance was synthesized. Few studies had the influence of contextual factors on CHW performance as their primary research focus. Contextual factors related to community (most prominently), economy, environment, and health system policy and practice were found to influence CHW performance. Socio-cultural factors (including gender norms and values and disease related stigma), safety and security and education and knowledge level of the target group were community factors that influenced CHW performance. Existence of a CHW policy, human resource policy legislation related to CHWs and political commitment were found to be influencing factors within the health system policy context. Health system practice factors included health service functionality, human resources provisions, level of decision-making, costs of health services, and the governance and coordination structure. All contextual factors can interact to shape CHW performance and affect the performance of CHW interventions or programmes. Research on CHW programmes often does not capture or explicitly discuss the context in which CHW interventions take place. This synthesis situates and discusses the influence of context on CHW and programme performance. Future health policy and systems research should better address the complexity of contextual influences on programmes. This insight can help policy makers and programme managers to develop CHW interventions that adequately address and respond to context to optimise performance.

Background Children with moderate acute malnutrition (MAM) have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs) for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations. Methods We defined MAM as mid-upper arm circumference (MUAC) of ≥11.0cm and <12.5cm with no bilateral pitting oedema to include Ethiopian government and World Health Organisation cut-offs. We prospectively surveyed 884 children aged 6–59 months living with MAM in a rural area of Ethiopia not eligible for a supplementary feeding programme. Weekly home visits were made for seven months (28 weeks), covering the end of peak malnutrition through to the post-harvest period (the most food secure window), collecting anthropometric, socio-demographic and food security data. Results By the end of the study follow up, 32.5% (287/884) remained with MAM, 9.3% (82/884) experienced at least one episode of SAM (MUAC <11cm and/or bilateral pitting oedema), and 0.9% (8/884) died. Only 54.2% of the children recovered with no episode of SAM by the end of the study. Of those who developed SAM half still had MAM at the end of the follow up period. The median (interquartile range) time to recovery was 9 (4–15) weeks. Children with the lowest MUAC at enrolment had a significantly higher risk of remaining with MAM and a lower chance of recovering. Conclusions Children with MAM during the post-harvest season in an area not eligible for SFP experience an extremely high incidence of SAM and a low recovery rate. Not having a targeted nutrition-specific intervention to address MAM in this context places children with MAM at excessive risk of adverse outcomes. Further preventive and curative approaches should urgently be considered. PMID:27100177

One of the permanent risks from an oil spill incident in the Mediterranean is associated with the heavy traffic in maritime transport, as well nowadays with the coastal and offshore installations related to the oil and gas industry. Such dense activity imposes on the coastal countries the need for preparing an operational response to major oil spill incidents. In the recent past, several policies related to oil spill response have been adopted internationally. At the regional level the Barcelona convention, recognizing pollution from oil spills as one of the major threats to the marine environment of the Mediterranean, initiated the preparedness for responding to major oil spill incidents, through various national and sub-regional contingency plans. At the European level the Member States was obliged to implement the EU Directive 2005/35, aimed at identifying the polluter and bringing them to prosecution. The response to an oil spill incident employs various measures and equipment. However, the success of such response depends greatly on the prediction of the movement and weathering of the oil spills. Such predictions may obtained through the operational application of advanced numerical oil spill models integrated with met-ocean forecasting data. A well established operational system for oil spill predictions in the Mediterranean is the MEDSLIK three dimensional model that predicts the transport, diffusion and spreading of oil spill and incorporates the fate processes of evaporation, emulsification, viscosity changes, dispersion into the water column and coastal impact and adhesion. MEDSLIK is integrated with the MyOCEAN regional and several downscaled ocean forecasting systems in the Mediterranean, contributing to the development of the GMES marine services. Moreover, MEDSLIK has been coupled with EMSA-CSN and ESA ASAR imageries, for short forward and backward predictions, to assist the response agencies in the implementation of the EU Directive 2005/35. From 2007 to 2011 more than a thousand possible ship originated oil slicks were detected by ASAR imageries in the Levantine Basin and then used for operational predictions by MEDSLIK. The successful operation of the MEDSLIK oil spill prediction system in the Levantine Basin has initiated efforts to implement a multi model approach to oil spill predictions in the Mediterranean through the realization of the recently approved project known as MedDESS4MS-Mediterranean Decision Support System for Maritime Safety, funded under the MED program. MEDESS4MS project is dedicated to the prevention of maritime risks and strengthening of maritime safety related to oil spill pollution in the Mediterranean. MEDESS4MS will deliver an integrated operational multi model oil spill prediction service in the Mediterranean, connected to existing monitoring platforms (EMSA-CSN, REMPEC, AIS), using the well established oil spill modeling systems, the data from the GMES Marine Core Services and the national ocean forecasting systems.

Introduction In the UK, 1 in 5 people aged 75 and over live with sight loss. Visually impaired older people (VIOP) have an above average incidence of falls and 1.3–1.9 times more likely to experience hip fractures, than the general population. Older people with eye diseases are ∼3 times more likely than those with good vision, to limit activities due to fear of falling. This feasibility study aims to adapt the group-based Falls Management Exercise (FaME) programme to the needs of VIOP and carry out an external pilot trial to inform the design of a future definitive randomised controlled trial. Methods and design A UK based 2-centre mixed methods, randomised, feasibility study will be conducted over 28 months. Stakeholder panels, including VIOP, will make recommendations for adaptations to an existing exercise programme (FaME), to meet the needs of VIOP, promoting uptake and adherence, while retaining required effective components of the exercise programme. 80 VIOP aged 60 and over, living at home, ambulant with or without a walking aid, will be recruited in Newcastle (n=40) and Glasgow (n=40) through National Health Service (NHS) Trusts and third sector partners. Participants randomised into the intervention arm will receive the adapted FaME programme. Participants randomised into the control arm will continue with usual activity. Outcomes are, recruitment rate, adherence and validated measures including fear of falling and quality of life. Postintervention in-depth qualitative interviews will be conducted with a purposive sample of VIOP (N=10). Postural stability instructors will be interviewed, before trial-specific training and following the intervention. Ethics and dissemination Ethics approval was secured through the National Research Ethics Service (NRES) Committee North East, Newcastle and North Tyneside 2. Glasgow Caledonian University was approved as a non-NHS site with local ethics approval. Findings will be disseminated through peer-reviewed journals, national and international conferences. Trial registration number ISRCTN16949845. PMID:27486124

To reach a consensus among public health faculty from various Spanish universities about the core public health competencies that should be integrated into the Veterinary Medicine degree training. The 3rd Forum of University Professors of Public Health was held at the School of Veterinary Medicine of the University of Cordoba (12-13 January 2016). Forty-two university professors and lecturers from nine Spanish universities with veterinary degrees participated in the forum. They were divided into five working groups during three working sessions to identify and classify core public health competencies for the Veterinary Medicine degree, propose public health contents for the identified competencies and organize such contents in thematic blocks. The results were discussed in different plenary sessions. The highest number of core competencies was identified in the activities related to the following public health functions: «Assessment of the population's health needs» and «Developing health policies». The final programme included basic contents organized into five units: 1) Fundamentals of public health; 2) Study and research in public health; 3) Production, animal health and environment; 4) Food security; and 5) Health education. The public health core competencies and contents identified in this Forum may be considered as a starting point to update public health training programmes for future veterinary professionals.

Inspired by the information theory, a new concept of re-programmable encrypted graphene-based coding metasurfaces was investigated at terahertz frequencies. A channel-coding function was proposed to convolutionally record an arbitrary information message onto unrecognizable but recoverable parity beams generated by a phase-encrypted coding metasurface. A single graphene-based reflective cell with dual-mode biasing voltages was designed to act as "0" and "1" meta-atoms, providing broadband opposite reflection phases. By exploiting graphene tunability, the proposed scheme enabled an unprecedented degree of freedom in the real-time mapping of information messages onto multiple parity beams which could not be damaged, altered, and reverse-engineered. Various encryption types such as mirroring, anomalous reflection, multi-beam generation, and scattering diffusion can be dynamically attained via our multifunctional metasurface. Besides, contrary to conventional time-consuming and optimization-based methods, this paper convincingly offers a fast, straightforward, and efficient design of diffusion metasurfaces of arbitrarily large size. Rigorous full-wave simulations corroborated the results where the phase-encrypted metasurfaces exhibited a polarization-insensitive reflectivity less than -10 dB over a broadband frequency range from 1 THz to 1.7 THz. This work reveals new opportunities for the extension of re-programmable THz-coding metasurfaces and may be of interest for reflection-type security systems, computational imaging, and camouflage technology.

There are limited accounts of community-based interventions for reducing distress or providing support for people with common mental disorders (CMDs) in low and middle-income countries. The recently implemented Atmiyata programme is one such community-based mental health intervention focused on promoting wellness and reducing distress through community volunteers in a rural area in the state of Maharashtra, India. This case study describes the content and the process of implementation of Atmiyata and how community volunteers were trained to become Atmiyata champions and mitras ( friends ). The Atmiyata programme trained Atmiyata champions to provide support and basic counselling to community members with common mental health disorders, facilitate access to mental health care and social benefits, improve community awareness of mental health issues, and to promote well-being. Challenges to implementation included logistical challenges (difficult terrain and weather conditions at the implementation site), content-related challenges (securing social welfare benefits for people with CMDs), and partnership challenges (turnover of public health workers involved in referral chain, resistance from public sector mental health specialists). The case study serves as an example for how such a model can be sustained over time at low cost. The next steps of the programme include evaluation of the impact of the Atmiyata intervention through a pre-post study and adapting the intervention for further scale-up in other settings in India.

Effects of a weight-gain restriction programme for obese pregnant women on sickness absence and pregnancy benefits

Abstract Objective To evaluate the effect of a weight-gain restriction programme for obese pregnant women on sickness absence days and pregnancy benefit days during pregnancy and postpartum. Design A prospective, controlled intervention study. The Swedish Social Security Agency's records were utilized to compile sickness absence and pregnancy benefit information. Setting Antenatal care clinics in the south-east of Sweden. Subjects One hundred fifty-five obese pregnant women who participated in a weight restriction program with weekly structured motivational and behavioural talks combined with aqua-aerobics during pregnancy. A total of 193 obese pregnant women with no intervention served as controls. Main outcome measures Sickness absence benefits and pregnancy benefits expressed as a percentage. Results On average women in the intervention group had 76.68 total full days of sickness absence benefit compared with 53.09days in the control group. Total full days of pregnancy benefits were 39.66% days and 41.41% for the intervention and control groups respectively. For the women who were on sick leave there were no differences between the groups in the amount of days taken. Conclusions Given the complexity of factors that have an influence on sickness absence leave, it is possible that programmes that do not address the influence of social aspects and attitudes towards sickness absence have limited effect.

Why have the majority of recent polio cases occurred in countries affected by Islamist militancy? A historical comparative analysis of the political determinants of polio in Nigeria, Somalia, Pakistan, Afghanistan and Syria.

PubMed

Kennedy, Jonathan

2016-01-01

This article aims to understand why the last few areas where polio remains are affected by armed conflicts involving militant organizations that use Islam to legitimize their activities. The first section critically analyses the argument that Muslims' animosity towards polio vaccination programmes is a consequence of their irrational, backward, anti-Western theology. This argument is depoliticizing, ahistorical and orientalist. Moreover, it does not explain why Islamist militant groups' attitudes to polio vaccination campaigns vary between countries. The second section analyses official documents, newspaper articles, interviews and historical and ethnographic accounts to understand the relationship between Islamist militant groups and polio in five countries - Nigeria, Somalia, Pakistan, Afghanistan and Syria - that account for 95% of the world's polio cases since 2012. I demonstrate that specific political grievances related to the postcolonial state and/or foreign military intervention help to explain variations in militant groups' attitudes to polio vaccination programmes. The paper concludes by considering the policy implications of the analysis. Improved access for polio vaccinators is not predicated on military victory against the militants but securing support of de facto political leaders. This can be achieved by developing a better understanding of the specific sociopolitical contexts in which immunization programmes operate.

Provably secure time distribution for the electric grid

DOE Office of Scientific and Technical Information (OSTI.GOV)

Smith IV, Amos M; Evans, Philip G; Williams, Brian P

We demonstrate a quantum time distribution (QTD) method that combines the precision of optical timing techniques with the integrity of quantum key distribution (QKD). Critical infrastructure is dependent on microprocessor- and programmable logic-based monitoring and control systems. The distribution of timing information across the electric grid is accomplished by GPS signals which are known to be vulnerable to spoofing. We demonstrate a method for synchronizing remote clocks based on the arrival time of photons in a modifed QKD system. This has the advantage that the signal can be veried by examining the quantum states of the photons similar to QKD.

When cube satellites first sprung on the scene in the late 1990s, they were seen as cheap, cute and novel. But today, these lunch-box-sized orbiters are heralded as powerful, cost-effective tools that help strengthen our national security presence in space. Los Alamos National Laboratory developed, built and tested CubeSats that are easily programmable from the ground, making them responsive to up-to-the-minute, mission-critical needs. While CubeSats are still the new kid on the celestial block, that’s about to change. These small, agile pieces of technology hold a universe of promise.

This chapter presents an infrastructure supporting the implementation of Executable Components (ECs). ECs represent S&D solutions at the implementation level, that is, by means of pieces of executable code. ECs are instantiated by the Serenity runtime Framework (SRF) as a result of requests coming from applications. The development of ECs requires programmers having specific technical knowledge about SERENITY, since they need to implement certain interfaces of the ECs according to SERENITY standards. Every EC has to implement, the interface between the SRF and the EC itself, and the interface that the EC offers to applications.

Hence, MICMoR brings together a considerably large network with currently 20 doctoral students and 55 scientists. MICMoR offers scientific and professional skills training, provides a state-of-the-art supervision concept, and fosters international exchange and interdisciplinary collaboration. In order to develop and advance its programme, MICMoR has committed itself to a self-imposed mid-term review in its third year, to monitor to which extent its original objectives have been reached, and to explore and identify where MICMoR has room for improvement. The evaluation especially focused on recruitment, supervision, training, networking and cooperation. Carried out by an external expert (Beate Scholz from scholz ctc), the evaluation was based on a mixed methods approach, i.e. combining a quantitative survey involving all doctoral candidates as well as their supervisors and focus groups with different MICMoR stakeholders. The evaluation has brought forward some highly interesting results, pinpointing challenges and opportunities of setting up a structured doctoral programme. Overall, the evaluation proved to be a useful tool for evidence-based programme and policy planning, and demonstrated a high level of satisfaction of supervisors and fellows. Supervision, with facets ranging from disciplinary feedback to career advice, is demanding and requires strong commitment and adequate human resources development by all parties involved. Thus, MICMoR plans to offer mentor coaching and calls on supervisors and mentors to form a community of learners with their doctoral students. To realize this vision, a long way lies ahead for all participants. Here, the evaluation provided useful suggestions on how to best use scarce time resources. Due to the fact that MICMoR's fellowships provide only supplemental funding for its fellows to participate in the programme, their base funding (salaries, stipends) needs to be secured independently, e.g. through project funds. However, this created a significant challenge as doctoral topics were determined more by the projects' research questions than by the research school's research focus. To improve this situation, MICMoR introduced some full stipends in its third year. We conclude that, in order to successfully run an interdisciplinary, multi-network research school, sufficient funds for its general framework, but also for doctoral stipends/salaries are needed to obtain a more accurate fit between the programme's research focus and the doctoral topics. Furthermore, a high level of commitment and identification with the programme of both, doctoral students and their supervisors, is required. Finally, regular review and programme assessment are essential for tailored programme development and strategy planning.

To evaluate the impact and appropriateness of programmes for the management and treatment of severe malnutrition in emergency situations. A central unified database was set up with all data and statistics provided by nutritional centres (NC) active in Burundi. The paper describes the case of Burundi as an example of the response of the humanitarian community to nutritional crisis. Since 1999, more than one million (1,054,210) severely malnourished patients were treated in NC established in Burundi. Peaks of beneficiaries were registered in 2000 and 2001; the admission rate started to decrease in 2002. In 2004, twenty therapeutic feeding centres (TFC) and 224 supplementary feeding centres (SFC) were active for the treatment of 127,420 beneficiaries. Nutritional programmes were present in every province with a coverage rate of 55%. The most convincing impact of the nutritional programme in Burundi was the reduction of mortality rate in children under 5 years of age; an impact on the prevalence of acute malnutrition could not be demonstrated. Children under 5 years old accounted for 62% of beneficiaries in TFC and 76% in SFC. TFC performance indicators fulfilled the minimum standards in disaster response; the performance of SFC was not so optimal with a low recovery rate (69% v. >80%) and a high non-respondent rate (16% v. <5%). With the combination of coverage and cure rate, the programme met 44% of the assessed needs in 2004. In Burundi the stabilisation of security conditions permitted a combination of humanitarian responses ranging from emergency activities to strengthening of community-based initiatives that could correct the coverage and impact limitations.

Aims and objectives In this critical literature review, we examine evidence-based interventions that target sexual behaviours of 18- to 25-year-old emerging adult women. Background Nurses and clinicians implement theory-driven research programmes for young women with increased risk of HIV/AIDS and sexually transmitted infections. Strategies to decrease transmission of HIV and sexually transmitted infections are rigorously evaluated and promoted by public health agencies such as the United States Centers for Disease Control and Prevention. While many interventions demonstrate episodic reductions in sexual risk behaviours and infection transmission, there is little evidence they build sustainable skills and behaviours. Programmes may not attend to contextual and affective influences on sexual behaviour change. Design Discursive paper. Methods We conducted a conceptually based literature review and critical analysis of the Centers for Disease Control and Prevention’s best-evidence and good-evidence HIV behavioural interventions. In this review, we examined three contextual and affective influences on the sexual health of emerging adult women: (1) developmental age, (2) reproduction and pregnancy desires and (3) sexual security or emotional responses accompanying relationship experiences. Results Our analyses revealed intervention programmes paid little attention to ways age, desires for pregnancy or emotional factors influence sexual decisions. Some programmes included 18- to 25-year-olds, but they made up small percentages of the sample and did not attend to unique emerging adult experiences. Second, primary focus on infection prevention overshadowed participant desires for pregnancy. Third, few interventions considered emotional mechanisms derived from relationship experiences involved in sexual decision-making. Conclusions Growing evidence demonstrates sexual health interventions may be more effective if augmented to attend to contextual and affective influences on relationship risks and decision-making. Modifying currently accepted strategies may enhance sustainability of sexual health-promoting behaviours. PMID:24988875

Fish farming as an innovative strategy for promoting food security in drought risk regions of Zimbabwe

PubMed Central

2017-01-01

This article examines the implementation of fish farming as an innovative and economic strategy for promoting food security and dietary diversities among vulnerable households in drought risk areas of Zimbabwe. The declining climatic conditions and lack of economic opportunities in Mwenezi district of Zimbabwe attracted the attention of three non-governmental organisations (NGOs) to implement fish farming as an innovative mechanism to stimulate food security and generate employment in the district. The article used a qualitative research approach that includes semi-structured interviews and secondary data. The purposive sampling technique was adopted to interview participants in Mwenezi district who were involved in fish farming to assess and explore the experiences and benefits they derive from such development projects. Results for the article revealed that fish farming was well embraced by local communities as it led to improvements in food security, household income and employment regeneration. The local government including traditional leadership (Chiefs and Headmen’s) supported the NGO activities as they benefited local communities. The article concludes that although fish farming was instrumental in regenerating employment, some participants still fail to participate because of laziness and desire to maintain dependency syndrome. The article recommends the NGOs to launch awareness campaigns in rural communities and increase networking with the donor community which is fundamental in attracting sustainable funding. The government can also promote fish farming in vulnerable rural communities by providing funding and capacity building programmes. PMID:29955350

This article explores the lived experiences of men with mild intellectual disabilities who have deliberately set a fire and are detained in a secure hospital. Semi-structured interviews were used to explore the subjective experiential claims of seven male firesetters with mild intellectual disabilities residing in a forensic intellectual disability hospital. Interpretative Phenomenological Analysis was used to interpret participants' meaning making of their firesetting. Five super-ordinate themes emerged from the analysis: (a) "the importance of the first fire," (b) "firesetting to escape distress," (c) "firesetting to enable positive emotional experiences," (d) "firesetting to communicate with services," and (e) "Fire Setters Treatment Programme." The analysis provides an understanding of why some firesetting behaviours emerge and highlights factors that contribute to the maintenance and desistence of repeat firesetting acts. The findings are considered in relation to evolving risk assessment measures and risk reduction strategies for facilitating rehabilitation into community settings. © The Author(s) 2015.

An account of co-ordination mechanisms for humanitarian assistance during the international response to the 1994 crisis in Rwanda.

Borton, J

1996-12-01

This paper examines the co-ordination strategies developed to respond to the Great Lakes crisis following the events of April 1994. It analyses the different functions and mechanisms which sought to achieve a co-ordinated response--ranging from facilitation at one extreme to management and direction at the other. The different regimes developed to facilitate co-ordination within Rwanda and neighbouring countries, focusing on both inter-agency and inter-country co-ordination issues, are then analysed. Finally, the paper highlights the absence of mechanisms to achieve coherence between the humanitarian, political and security domains. It concludes that effective co-ordination is critical not only to achieve programme efficiency, but to ensure that the appropriate instruments and strategies to respond to complex political emergencies are in place. It proposes a radical re-shaping of international humanitarian, political and security institutions, particularly the United Nations, to improve the effectiveness of humanitarian and political responses to crises such as that in the Great Lakes.

Global food security demands the development and delivery of new technologies to increase and secure cereal production on finite arable land without increasing water and fertilizer use. There are several options for boosting wheat yields, but most offer only small yield increases. Wheat is an inbred plant, and hybrids hold the potential to deliver a major lift in yield and will open a wide range of new breeding opportunities. A series of technological advances are needed as a base for hybrid wheat programmes. These start with major changes in floral development and architecture to separate the sexes and force outcrossing. Male sterility provides the best method to block self-fertilization, and modifying the flower structure will enhance pollen access. The recent explosion in genomic resources and technologies provides new opportunities to overcome these limitations. This review outlines the problems with existing hybrid wheat breeding systems and explores molecular-based technologies that could improve the hybrid production system to reduce hybrid seed production costs, a prerequisite for a commercial hybrid wheat system.

2015-01-01

Internet application technologies, such as cloud computing and cloud storage, have increasingly changed people’s lives. Websites contain vast amounts of personal privacy information. In order to protect this information, network security technologies, such as database protection and data encryption, attract many researchers. The most serious problems concerning web vulnerability are e-mail address and network database leakages. These leakages have many causes. For example, malicious users can steal database contents, taking advantage of mistakes made by programmers and administrators. In order to mitigate this type of abuse, a website information disclosure assessment system is proposed in this study. This system utilizes a series of technologies, such as web crawler algorithms, SQL injection attack detection, and web vulnerability mining, to assess a website’s information disclosure. Thirty websites, randomly sampled from the top 50 world colleges, were used to collect leakage information. This testing showed the importance of increasing the security and privacy of website information for academic websites. PMID:25768434

Global System for Mobile communication (GSM) is the most widespread technology for mobile communications in the world and serving over 7 billion users. Since first publication of system documentation there has been notified a potential safety problem's occurrence. Selected types of attacks, based on the analysis of the technical feasibility and the degree of risk of these weaknesses, were implemented and demonstrated in laboratory of the VSB-Technical University of Ostrava, Czech Republic. These vulnerabilities were analyzed and afterwards possible attacks were described. These attacks were implemented using open-source tools, software programmable radio USRP (Universal Software RadioPeripheral) and DVB-T (Digital Video Broadcasting - Terrestrial) receiver. GSM security architecture is being scrutinized since first public releases of its specification mainly pointing out weaknesses in authentication and ciphering mechanisms. This contribution also summarizes practically proofed and used scenarios that are performed using opensource software tools and variety of scripts mostly written in Python. Main goal of this paper is in analyzing security issues in GSM network and practical demonstration of selected attacks.

Resilient patriarchy: public authority and women's (in)security in Karamoja, Uganda.

2018-01-01

This paper draws on fieldwork conducted in 2011 and 2016 to explore the differing experiences of Karamojong women following the Government of Uganda's most recent disarmament programme. Besides being deprived of their guns, Karamojong communities have lost most of the cattle on which their livelihoods and way of life were centred. The study assesses whether or not women's experience of patriarchy has changed in these new circumstances, and, if so, how this impacts on their security and control of resources, or the absence of them. It maps, using information primarily supplied by women, public authorities from below, and evaluates if and how they respond to women's protection and survival needs, as well as if current development/humanitarian interventions are of sustainable benefit to Karamojong women. The paper concludes that apparent shifts in gender relations are probably superficial, contingent on continuing food aid, and that economic development and positive social change for women remain elusive. © 2018 The Author(s).

Submillimetre wave imaging and security: imaging performance and prediction

NASA Astrophysics Data System (ADS)

Appleby, R.; Ferguson, S.

2016-10-01

Within the European Commission Seventh Framework Programme (FP7), CONSORTIS (Concealed Object Stand-Off Real-Time Imaging for Security) has designed and is fabricating a stand-off system operating at sub-millimetre wave frequencies for the detection of objects concealed on people. This system scans people as they walk by the sensor. This paper presents the top level system design which brings together both passive and active sensors to provide good performance. The passive system operates in two bands between 100 and 600GHz and is based on a cryogen free cooled focal plane array sensor whilst the active system is a solid-state 340GHz radar. A modified version of OpenFX was used for modelling the passive system. This model was recently modified to include realistic location-specific skin temperature and to accept animated characters wearing up to three layers of clothing that move dynamically, such as those typically found in cinematography. Targets under clothing have been modelled and the performance simulated. The strengths and weaknesses of this modelling approach are discussed.

Quantum key distribution (QKD) is a technology with the potential capability to achieve information-theoretic security. Phasecoding is an important approach to develop practical QKD systems in fiber channel. In order to improve the phase-coding modulation rate, we proposed a new digital-modulation method in this paper and constructed a compact and robust prototype of QKD system using currently available components in our lab to demonstrate the effectiveness of the method. The system was deployed in laboratory environment over a 50 km fiber and continuously operated during 87 h without manual interaction. The quantum bit error rate (QBER) of the system was stable with an average value of 3.22% and the secure key generation rate is 8.91 kbps. Although the modulation rate of the photon in the demo system was only 200 MHz, which was limited by the Faraday-Michelson interferometer (FMI) structure, the proposed method and the field programmable gate array (FPGA) based electronics scheme have a great potential for high speed QKD systems with Giga-bits/second modulation rate.

The Gateway Paper--financing health in Pakistan and its linkage with health reforms.

PubMed

Nishtar, Sania

2006-12-01

Pakistan currently principally uses three modes of financing health--taxation, out of pocket payments and donor contributions of which the latter is the least significant in terms of size. Less than 3.6% of the employees are covered under the social security scheme and there is a limited social protection mechanism, which collectively serves the health needs of 3.4% of the population. The main issues in health financing include low spending, lack of attention to alternate sources of financing and issues with fund mobilization and utilization. With respect to the first, health reforms proposed as part of the Gateway Paper make a strong case for promoting the reallocation of tax-based revenues and developing sustainable alternatives to low levels of public spending on health. With respect to alternative sources of health financing, the Gateway Paper lays stress on exploring policy options for private health insurance, broadening the base of Employees Social Security, creating a Federal Employees Social Security Programme, developing social health insurance within the framework of a broad-based social protection strategy, which scopes beyond the formally employed sector, establishing a widely inclusive safety net for the poor; mainstreaming philanthropic grants as a major source of health financing; developing a conducive tax configuration; generating greater corporate support for social sector causes within the framework of the concept of Corporate Social Responsibility and developing cost-sharing programmes, albeit with safeguards. The Gateway Paper regards efficient fund utilization a priority and lays stress on striking a balance between minimizing costs, controlling costs and using resources more efficiently and equitably--in other words, getting the best value for the money, on the one hand, and increasing the pool of available resources, on the other. Specific interventions such as the promotion of transparent financial administration, budgeting and cost controls and enhancing the capacity to overcome onerous financial management procedures and decentralizing decision-making are underscored as a priority as is the need for ensuring greater financial procedural clarity at the federal-provincial-district interface.

We estimated the prevalence of food insecurity among people who inject drugs (PWID) in Los Angeles and San Francisco and explored correlates of food insecurity. A cross-sectional study that measured 30 d food insecurity using the US Adult Food Security Survey ten-item Module developed by the US Department of Agriculture. Food insecurity was defined as including low and very low food security. Two cities in the state of California, USA. Male and female active PWID (n 777). Among participants, 58 % reported food insecurity and 41 % reported very low food security. Food-insecure PWID were more likely to report being homeless (prevalence ratio (PR)=1·20; 95 % CI 1·05, 1·37), chest pain in the past 12 months (PR=1·19; CI 1·06, 1·35), acquiring syringes from someone who goes to a syringe exchange programme (PR=1·27; 95 % CI 1·13, 1·43) and feeling at risk for arrest for possession of drug paraphernalia (PR=1·30; 95 % CI 1·15, 1·46). Current food insecurity was common among PWID in these two cities, yet few factors were independently associated with food insecurity. These data suggest that broad strategies to improve food access for this high-risk population are urgently needed.

Privacy and information security risks in a technology platform for home-based chronic disease rehabilitation and education

PubMed Central

2013-01-01

Background Privacy and information security are important for all healthcare services, including home-based services. We have designed and implemented a prototype technology platform for providing home-based healthcare services. It supports a personal electronic health diary and enables secure and reliable communication and interaction with peers and healthcare personnel. The platform runs on a small computer with a dedicated remote control. It is connected to the patient’s TV and to a broadband Internet. The platform has been tested with home-based rehabilitation and education programs for chronic obstructive pulmonary disease and diabetes. As part of our work, a risk assessment of privacy and security aspects has been performed, to reveal actual risks and to ensure adequate information security in this technical platform. Methods Risk assessment was performed in an iterative manner during the development process. Thus, security solutions have been incorporated into the design from an early stage instead of being included as an add-on to a nearly completed system. We have adapted existing risk management methods to our own environment, thus creating our own method. Our method conforms to ISO’s standard for information security risk management. Results A total of approximately 50 threats and possible unwanted incidents were identified and analysed. Among the threats to the four information security aspects: confidentiality, integrity, availability, and quality; confidentiality threats were identified as most serious, with one threat given an unacceptable level of High risk. This is because health-related personal information is regarded as sensitive. Availability threats were analysed as low risk, as the aim of the home programmes is to provide education and rehabilitation services; not for use in acute situations or for continuous health monitoring. Conclusions Most of the identified threats are applicable for healthcare services intended for patients or citizens in their own homes. Confidentiality risks in home are different from in a more controlled environment such as a hospital; and electronic equipment located in private homes and communicating via Internet, is more exposed to unauthorised access. By implementing the proposed measures, it has been possible to design a home-based service which ensures the necessary level of information security and privacy. PMID:23937965

Data security and patient confidentiality: the manager's role.

PubMed

Fisher, F; Madge, B

1996-10-01

The maintenance of patient confidentiality is of utmost importance in the doctor patient relationship. With the advent of networks such as the National Health Service Wide Area Network in the UK, the potential to transmit identifiable clinical data will become greater. Links between general practitioners (GPs) and hospitals will allow the rapid transmission of data which if intercepted could be potentially embarrassing to the patient concerned. In 1994 the British Medical Association launched a draft bill on privacy and confidentiality and in association with this bill it is pushing for encryption of all clinical data across electronic networks. The manager's role within an acute hospital, community units and general practice, is to ensure that all employees are aware of the principles of data protection, security of hospital computer systems and that no obvious breaches of security can occur at publicly accessible terminals. Managers must be kept up to date with the latest developments in computer security such as digital signatures and be prepared to instigate these developments where practically possible. Managers must also take responsibility for the monitoring of access to terminals and be prepared to deal severely with staff who breach the code of confidentiality. Each manager must be kept informed of employees status with regard to their 'need to know' clearance level and also to promote confidentiality of patient details throughout the hospital. All of the management team must be prepared to train new staff in the principles of data security as they join the organisation and recognise their accountability if the programme fails. Data security and patient confidentiality is a broad responsibility in any healthcare organisation, with the Chief Executive accountable. In family practice, the partners are responsible and accountable. The British Medical Association believes as a matter of policy, that allowing access to personal health data without the patients consent, except in a legally allowable situation, should be a statutory offence.

To describe the case of Congo as an example of the assessment and appropriateness of donor operational and sectoral strategies in a complex emergency. The paper reports the findings of an external evaluation of operations financed by the European Commission Humanitarian Office in the Democratic Republic of Congo (DRC). The Congolese health system is suffering from severe deterioration. What is functioning in the public health context is donor-dependent with high costs and limited coverage. Despite a relatively favourable agro-climatic situation, food shortage and famine severely affect the nutritional status of large population groups. In this context, humanitarian programmes have generally improved access to health care and the nutritional status of beneficiaries. The reduction of malnutrition in project areas is often demonstrated even though the context did not permit consolidation of these results. Malnutrition continues to claim a massive cost of lives owing to the effect of widespread food insecurity that follows a circular cause-and-effect pattern of very low food production and extreme poverty. The current context in DRC does not correspond yet to 'post-crisis': neither at population level with regard to indicators of poverty, malnutrition, disease and death, nor at institutional level, with regard to state support to institutions. In these situations, the international community is often called upon to replace the state as service provider. Integrated humanitarian actions should be the future of relief projects in DRC. Health, nutrition and food security components should be considered a standard public health intervention strategy representing the most sensible approach to address the needs of the affected population.

To determine the prevalence of adult malnutrition and associated risk factors in a post-conflict area of northern Uganda. A cross-sectional community survey was performed from September 2011 to June 2013. All registered residents in Gulu Health and Demographic Surveillance System aged 15 years and older were considered eligible. Trained field assistants collected anthropometric measurements (weight and height) and administered questionnaires with information on sociodemographic characteristics, food security, smoking and alcohol. Nutritional status was classified by body mass index. In total, 2062 men and 2924 women participated and were included in the analyses. The prevalence of underweight was 22.3% for men and 16.0% for women, whereas the prevalence of overweight was 1.5% for men and 7.6% for women. In men, underweight was associated with younger (15-19 years) and older age (>55 years) (P < 0.001), being divorced/separated [odds ratio (OR) = 1.91 (95% confidence interval (CI): 1.21-2.99] and smoking (OR = 2.13, 95% CI: 1.67-2.73). For women, underweight was associated with older age (P < 0.001) and hungry-gap rainy season (May-July) (OR = 1.33, 95% CI: 1.04-1.69). Widowed or divorced/separated women were not more likely to be underweight. No association was found between education, alcohol consumption or food security score and underweight. Our findings are not in line with the conventional target groups in nutritional programmes and highlight the importance of continuous health and nutritional assessments of all population groups that reflect local social determinants and family structures. © 2016 John Wiley & Sons Ltd.

Food insecurity, food assistance and weight status in US youth: new evidence from NHANES 2007-08.

To investigate food assistance participation as a risk factor for overweight and obesity in youth, and food insecurity as an effect modifier. The sample included youth ages 4-17, in families ≤200% of the federal poverty line in the 2007-2008 National Health and Nutrition Examination Survey (n = 1321). Food insecurity was measured with the US Department of Agriculture survey module. Food assistance participation was assessed for Supplemental Nutrition Assistance Program, Special Supplemental Nutrition Program for Women, Infants and Children and school meals. Body size was classified by age- and sex-specific body mass index (BMI) percentile, BMI z-score and waist circumference percentile. Regression models with direct covariate adjustment and programme-specific propensity scores, stratified by food insecurity, estimated associations between food assistance participation and body size. Food assistance participation was not associated with increased body size among food-insecure youth in models with direct covariate adjustment or propensity scores. Compared with low-income, food-secure youth not participating in food assistance, BMI z-scores were higher among participants in models with direct covariate adjustment (0.27-0.38 SD and 0.41-0.47 SD, for boys and girls, respectively). Using propensity scores, results were similar for boys, but less so for girls. Food assistance programme participation is associated with increased body size in food-secure youth, but not food-insecure youth. Using both direct covariate adjustment and a propensity score approach, self-selection bias may explain some, but not all, of the associations. Providing healthy food assistance that improves diet quality without contributing to excessive intake remains an important public health goal. © 2013 The Authors.

Providing a secured airway is of paramount importance in cardiopulmonary resuscitation. Although intubating the trachea is yet seen as gold standard, this technique is still reserved to experienced healthcare professionals. Compared to bag-valve facemask ventilation, however, the insertion of a laryngeal mask airway offers the opportunity to ventilate the patient effectively and can also be placed easily by lay responders. Obviously, it might be inserted without detailed background knowledge.The purpose of the study was to investigate the intuitive use of airway devices by first-year medical students as well as the effect of a simple, but well-directed training programme. Retention of skills was re-evaluated six months thereafter. The insertion of a LMA-Classic and a LMA-Fastrach performed by inexperienced medical students was compared in an airway model. The improvement on their performance after a training programme of overall two hours was examined afterwards. Prior to any instruction, mean time to correct placement was 55.5 +/- 29.6 s for the LMA-Classic and 38.1 +/- 24.9 s for the LMA-Fastrach. Following training, time to correct placement decreased significantly with 22.9 +/- 13.5 s for the LMA-Classic and 22.9 +/- 19.0 s for the LMA-Fastrach, respectively (p < 0.05). After six months, the results are comparable prior (55.6 +/- 29.9 vs 43.1 +/- 34.7 s) and after a further training period (23.5 +/- 13.2 vs 26.6 +/- 21.6, p < 0.05). Untrained laypersons are able to use different airway devices in a manikin and may therefore provide a secured airway even without having any detailed background knowledge about the tool. Minimal theoretical instruction and practical skill training can improve their performance significantly. However, refreshment of knowledge seems justified after six months.

Working towards a European Geological Data Infrastructure

2013-04-01

The increasing importance of geological information for policy, regulation and business needs at European and international level has been recognized by the European Parliament and the European Commission, who have called for the development of a common European geological knowledge base. The societal relevance of geoscience data/information is clear from many current issues such as shale gas exploration (including environmental impacts), the availability of critical mineral resources in a global economy, management and security with regard to geohazards (seismic, droughts, floods, ground stability), quality of (ground-)water and soil and societal responses to the impacts of climate change. The EGDI-Scope project responds to this, aiming to prepare an implementation plan for a pan-European Geological Data Infrastructure (EGDI), under the umbrella of the FP7 e- Infrastructures program. It is envisaged that the EGDI will build on geological datasets and models currently held by the European Geological Surveys at national and regional levels, and will also provide a platform for datasets generated by the large number of relevant past, ongoing and future European projects which have geological components. With European policy makers and decision makers from (international) industry as the main target groups (followed by research communities and the general public) stakeholder involvement is imperative to the successful realization and continuity of the EGDI. With these ambitions in mind, the presentation will focus on the following issues, also based on the first results and experiences of the EGDI-Scope project that started mid-2012: • The organization of stakeholder input and commitment connected to relevant 'use cases' within different thematic domains; a number of stakeholder representatives is currently involved, but the project is open to more extensive participation; • A large number of European projects relevant for data delivery to EGDI has been reviewed; what can we conclude and what is the way forward? • The project has evaluated relevant existing interoperable infrastructures revealing a typology of infrastructures that may be useful models for the EGDI; • Planning for the EGDI also need to be integrated with other relevant international initiatives and programs such as GMES, GEO and EPOS, and with legally binding regulations like INSPIRE. The outcomes of these relevant evaluations and activities will contribute to the implementation plan for the EGDI including the prioritization of relevant datasets and the most important functional, technical (design, use of standards), legal and organizational requirements.

From January to April 2009, 30 patients at the spinal cord injury ambulatory clinic at Hospital das Clínicas of Unicamp were analysed by some epidemiologic characteristics: age, profession, type and level of their paralysis, origin and time of injury. All patients had complete spinal cord injury (ASIA); 24 patients were men and six were women, the mean age was 34.6 years (range, 10-64 years), two patients were children. Twenty-one patients were paraplegic and nine were tetraplegic; causes included automobile accident (12), run over (three), diving (four), bicycle accident (one), motorcycle accident (three), gunshot wound (six), thoracic tuberculosis (one), and lumbar surgery (one). The mean lesion time was 8.2 years (range, 1-15 years). Two patients were retired. The results suggested that spinal cord injury affects mainly young active men. It is necessary to develop incisive actions to prevent accidents, specially directed to traffic security.

Given the ethical aspects of vaccination policies and current threats to public trust in vaccination, it is important that governments follow clear criteria for including new vaccines in a national programme. The Health Council of the Netherlands developed such a framework of criteria in 2007, and has been using this as basis for advisory reports about several vaccinations. However, general criteria alone offer insufficient ground and direction for thinking about what the state ought to do. In this paper, we present and defend two basic ethical principles that explain why certain vaccinations are the state's moral-political responsibility, and that may further guide decision-making about the content and character of immunisation programmes. First and foremost, the state is responsible for protecting the basic conditions for public health and societal life. Secondly, states are responsible for promoting and securing equal access to basic health care, which may also include certain vaccinations. We argue how these principles can find reasonable support from a broad variety of ethical and political views, and discuss several implications for vaccination policies.

After 9/11/2001 the United States launched a global War on Terror. As part of this War, terrorism suspects were detained by the U.S. military and by the C.I.A. It is now widely recognized that the United States tortured a number of these detainees in the context of its 'enhanced interrogation' programme. This article examines how and why U.S. organizations developed standards that allowed healthcare professionals to become involved in torture; why the standards developed by U.S. security institutions failed to control the actions of enhanced interrogation personnel on the ground; and what the role of standards were in stopping the enhanced interrogation initiative. The article concludes by discussing the general lessons that the enhanced interrogation programme has for social science research on standards, namely that individuals can experience ambivalence when caught between competing organizational and professional standards and that it might be inherently difficult to successfully enact certain protocols when these relate to deviant or destructive acts.

Preparing to understand and use science in the real world: interdisciplinary study concentrations at the Technical University of Darmstadt.

PubMed

Liebert, Wolfgang J

2013-12-01

In order to raise awareness of the ambiguous nature of scientific-technological progress, and of the challenging problems it raises, problems which are not easily addressed by courses in a single discipline and cannot be projected onto disciplinary curricula, Technical University of Darmstadt has established three interdisciplinary study concentrations: "Technology and International Development", "Environmental Sciences", and "Sustainable Shaping of Technology and Science". These three programmes seek to overcome the limitations of strictly disciplinary research and teaching by developing an integrated, problem-oriented approach. For example, one course considers fundamental nuclear dilemmas and uses role-playing techniques to address a controversy in the area of nuclear security. At the same time, incorporating interdisciplinary teaching into a university that is organized around mono- or multi-disciplinary faculties also poses a number of challenges. Recognition in disciplinary curricula, and appropriate organizational support and funding are examples of those challenges. It is expected that science and engineering students, empowered by such interdisciplinary study programmes, will be better prepared to act responsibly with regard to scientific and technological challenges.

Even powerful computational techniques like simulation endure limitations in their validity domain. Consequently using simulation models requires cautions to avoid making biased design decisions for new aeronautical products on the basis of inadequate simulation results. Thus the fidelity, accuracy and validity of simulation models shall be monitored in context all along the design phases to build confidence in achievement of the goals of modelling and simulation.In the CRESCENDO project, we adapt the Credibility Assessment Scale method from NASA standard for models and simulations from space programme to the aircraft design in order to assess the quality of simulations. The proposed eight quality assurance metrics aggregate information to indicate the levels of confidence in results. They are displayed in management dashboard and can secure design trade-off decisions at programme milestones.The application of this technique is illustrated in aircraft design context with specific thermal Finite Elements Analysis. This use case shows how to judge the fitness- for-purpose of simulation as Virtual testing means and then green-light the continuation of Simulation Lifecycle Management (SLM) process.

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals (MDGs). Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse and interpret available information on infant and child feeding and the nutrition situation of children <2 years of age in Senegal, as one of the six targeted countries. These findings will be used to assist in identifying inconsistencies and filling gaps in current programming. Between August and December 2008, key informants responsible for conducting IYCN-related activities in Senegal were interviewed, and 157 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of HIV, management of acute malnutrition, food security and hygienic practices. Nearly all of the key IYCN topics were addressed, specifically or generally, in national policy documents. Senegal reported substantial improvements since the 1990s towards reducing infant and young child mortality and underweight, and increasing exclusive breastfeeding among infants <6 months of age (34%). Senegal is one of the few countries in the region that is nearly on track for reaching related MDGs. Notable activities that may have played a role include: (1) vitamin A supplementation was expanded to nearly semi-annual national campaigns starting in 1994; (2) the Ministry of Health partnered with several national and international agencies to scale up child survival activities under the umbrella of the Basic Support for Institutionalizing Child Survival (1994-2006); (3) a national nutrition division was developed to support a national nutrition strengthening programme; (4) the national nutrition counsel was organized to coordinate nutritional activities across various organizations and governmental sectors, involving representatives from health, agriculture and surveillance; and (5) an integrated communications programme was developed to support harmonized behaviour change communication tools for the health and nutrition sectors. Along with these activities, a number of programme evaluations were conducted to ensure that programmes obtain desired results. Although useful, these evaluations were not rigorous enough to identify effective programmes that contributed to the mentioned reductions in the prevalence of underweight and mortality, and increases in exclusive breastfeeding. The policy and programme framework is well established for support of optimal IYCN practices in Senegal. Despite the recent improvements in infant and young child nutritional status indicators, there is still much to do. Greater resources and continued capacity building are needed to: (1) conduct necessary research for adapting training materials and programme protocols to programmatic needs; (2) improve and carry out monitoring and evaluation that identify effective programme components; and (3) apply these findings in developing, expanding and improving effective programmes. © 2011 Blackwell Publishing Ltd.

The GMES Sentinel-1 Earth Radar Observatory, a projects co-funded by the European Union and the European Space Agency (ESA), is a constellation of C-band radar satellites. The satellites have been conceived to be a continuous and reliable source of C-band SAR imagery for operational application such as mapping of global landmasses, coastal zones and monitoring of shipping routes. ESA is responsible for the development of the Sentinel-1 satellites that are built by an industrial consortium headed by Thales Alenia Space Italy (TASI) as Prime Contractor. TAS-I is also directly responsible for the production of the Spacecraft Bus and the Avionic S/S including the Avionic SW (ASW), which is characterized by: · The high performances of its attitude and orbit determination and control function; · Scheduling of the imaging activity on position basis with high geo-location performances; · High on board autonomy both in routine and contingency situations. This paper is focused on the Sentinel-1 Avionic SW, which has currently been qualified by TAS-I for Flight. It covers both the SW architecture and development process areas: · Avionic SW context; · Avionic SW architecture; · Flexibility of PUS-based on-board autonomy and FDIR; · Validation and Qualification activities;

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals (MDGs). Therefore, several international agencies joined to 'reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse, and interpret available information on infant and child feeding, and the nutrition situation of children <2 years of age in Chad, as one of the six targeted countries. These findings are available to assist in identifying inconsistencies and filling gaps in current programming. Between June and October of 2008, key informants responsible for IYCN-related activities in Chad were interviewed, and 53 documents were examined on the following themes: the promotion of optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, management of acute malnutrition, prevention of mother-to-child transmission of human immunodeficiency virus (HIV), food security, and promotion of good hygienic practices. Chad is not on track to reaching the MDGs of reducing mortality by two-thirds and malnutrition by half among children <5 years of age between 1990 and 2015. Most of the key IYCN topics were addressed in a national policy to combat malnutrition and micronutrient deficiencies. No national nutrition policy was yet ratified in Chad, so the target of many documents reviewed was the malnourished child. Researchers have identified some barriers to optimal feeding practices. However, the majority of these surveys were small scale, so they do not necessarily provide information relevant to the general population. Expanded surveys would be needed for developing evidence-based educational messages targeted to local needs. Reviewed training materials and related programmes being implemented in Chad provide specific guidance for nearly all of the key IYCN topics, except for appropriate feeding choices for the prevention of mother-to-child transmission of HIV. Some of the programmes were intended for national coverage, but we could not confirm whether these programmes were actually implemented nationally. Monitoring and evaluation reports were available for some small-scale programmes, but few of these evaluated whether IYCN-specific programme components were implemented as designed and none evaluated whether participants adopted the promoted feeding practices. Establishment of the policy and programme framework has commenced for improving IYCN practices. Formative research is needed to guide the development of evidence-based training materials and programmes to address the nutritional needs of infants and children. Once more directed programmes are established, there is a further need for rigorous monitoring and evaluation to ensure that training is adequate, programmes are implemented as designed, and effective programmes are identified for expansion nationally. Evaluations are also needed to determine where human and institutional capacity building is needed to carry out these activities as they are implemented. National and international support will be required to complete these enhancements, and thus improve the health and nutritional status of infants and young children in Chad. © 2011 Blackwell Publishing Ltd.

FixO3 : Early progress towards Open Ocean observatory Data Management Harmonisation

2014-05-01

Since 2002 there has been a sustained effort, supported as European framework projects, to harmonise both the technology and the data management of Open Ocean fixed observatories run by European nations. FixO3 started in September 2013, and for 4 years will coordinate the convergence of data management best practice across a constellation of moorings in the Atlantic, in both hemispheres, and in the Mediterranean. To ensure the continued existence of these unique sources of oceanographic data as sustained observatories it is vital to improve access to the data collected, both in terms of methods of presentation, real-time availability, long-term archiving and quality assurance. The data management component of FixO3 will improve access to marine observatory data by harmonizing data management standards and workflows covering the complete life cycle of data from real time data acquisition to long-term archiving. Legal and data policy aspects will be examined to identify transnational barriers to open-access to marine observatory data. A harmonised FixO3 data policy is being synthesised from the partner's existing policies, which will overcome the identified barriers, and provide a formal basis for data exchange between FixO3 infrastructures. Presently, the interpretation and implementation of accepted standards has considerable incompatibilities within the observatory community, and these different approaches will be unified into the FixO3 approach. Further, FixO3 aims to harmonise data management and standardisation efforts with other European and international marine data and observatory infrastructures. The FixO3 synthesis will build on the standards established in other European infrastructures such as EDMONET, SEADATANET, PANGAEA, EuroSITES (European contribution to JCOMMP OceanSITES programme), and MyOcean (the Marine Core Service for GMES) infrastructures as well as relevant international infrastructures and data centres such as the ICOS Ocean Thematic Centre. The data management efforts are central to FixO3. Combined with the procedural and technological harmonisation, tackled in separate work packages, the FixO3 network of observatories will efficiently and cost effectively provide a consistent resource of quality controlled accessible oceanographic data The project website www.fixo3.eu is being developed as both a data showcase and single distribution point, and with database driven tools will enable the sharing of information between the observatories in the most smart and cost effective way. The network of knowledge built throughout the project will become a legacy resource that will ensure access to the unique ensemble data sets only achievable at these key observatories.

This paper describes “IPSec(IP Security) VPN system" and how it attains a theoretical maximum performance on Gigabit Ethernet. The Conventional System is implemented by software. However, the system has several bottlenecks which must be overcome to realize a theoretical maximum performance on Gigabit Ethernet. Thus, we newly propose IPSec VPN System with the FPGA(Field Programmable Gate Array) based hardware architecture, which transmits a packet by the pipe-lined flow processing and has 6 parallel structure of encryption and authentication engines. We show that our system attains the theoretical maximum performance in the short packet which is difficult to realize until now.

When cube satellites first sprung on the scene in the late 1990s, they were seen as cheap, cute and novel. But today, these lunch-box-sized orbiters are heralded as powerful, cost-effective tools that help strengthen our national security presence in space. Los Alamos National Laboratory developed, built and tested CubeSats that are easily programmable from the ground, making them responsive to up-to-the-minute, mission-critical needs. While CubeSats are still the new kid on the celestial block, that’s about to change. These small, agile pieces of technology hold a universe of promise.

To identify how 10 low- and middle-income countries achieved accelerated progress, ahead of comparable countries, towards meeting millennium development goals 4 and 5A to reduce child and maternal mortality. We synthesized findings from multistakeholder dialogues and country policy reports conducted previously for the Success Factors studies in 10 countries: Bangladesh, Cambodia, China, Egypt, Ethiopia, the Lao People's Democratic Republic, Nepal, Peru, Rwanda and Viet Nam. A framework approach was used to analyse and synthesize the data from the country reports, resulting in descriptive or explanatory conclusions by theme. Successful policy and programme approaches were categorized in four strategic areas: leadership and multistakeholder partnerships; health sector; sectors outside health; and accountability for resources and results. Consistent and coordinated inputs across sectors, based on high-impact interventions, were assessed. Within the health sector, key policy and programme strategies included defining standards, collecting and using data, improving financial protection, and improving the availability and quality of services. Outside the health sector, strategies included investing in girls' education, water, sanitation and hygiene, poverty reduction, nutrition and food security, and infrastructure development. Countries improved accountability by strengthening and using data systems for planning and evaluating progress. Reducing maternal and child mortality in the 10 fast-track countries can be linked to consistent and coordinated policy and programme inputs across health and other sectors. The approaches used by successful countries have relevance to other countries looking to scale-up or accelerate progress towards the sustainable development goals.

Food security is a global concern and substantial yield increases in cereal crops are required to feed the growing world population. Wheat is one of the three most important crops for human and livestock feed. However, the complexity of the genome coupled with a decline in genetic diversity within modern elite cultivars has hindered the application of marker-assisted selection (MAS) in breeding programmes. A crucial step in the successful application of MAS in breeding programmes is the development of cheap and easy to use molecular markers, such as single-nucleotide polymorphisms. To mine selected elite wheat germplasm for intervarietal single-nucleotide polymorphisms, we have used expressed sequence tags derived from public sequencing programmes and next-generation sequencing of normalized wheat complementary DNA libraries, in combination with a novel sequence alignment and assembly approach. Here, we describe the development and validation of a panel of 1114 single-nucleotide polymorphisms in hexaploid bread wheat using competitive allele-specific polymerase chain reaction genotyping technology. We report the genotyping results of these markers on 23 wheat varieties, selected to represent a broad cross-section of wheat germplasm including a number of elite UK varieties. Finally, we show that, using relatively simple technology, it is possible to rapidly generate a linkage map containing several hundred single-nucleotide polymorphism markers in the doubled haploid mapping population of Avalon × Cadenza. © 2011 The Authors.

Agriculture and food systems play a central role in nutrition by supplying nutritious, healthy and affordable foods. When integrated with nutrition education for behaviour change, agricultural interventions that supply diverse affordable foods from all food groups have great scope for improving young child and family diets. In 2014, process reviews were conducted in Cambodia and Malawi of food security projects that provided agricultural support and community-based nutrition education on improved infant and young child feeding (IYCF). In both countries, household visits were carried out with mothers/caregivers, and interviews and Focus Group Discussions (FGDs) were conducted with purposively selected project stakeholders (53 in Cambodia, 170 in Malawi), including government staff from the agriculture and health sectors. Results highlight that adoption of improved IYCF practices was facilitated by participation in nutrition education and practical cooking sessions, and supportive family and community structures. Barriers faced by families and caregivers were identified, such as women's workload and lack of access to high quality foods, namely fruits, vegetables, legumes, nuts and animal source foods. Implementation challenges regarding coordination of cross-sectoral targeting strategies and capacities of extension services to sustain community-based IYCF nutrition education need to be addressed to improve programme effectiveness and impact. The project lessons from Cambodia and Malawi are useful for integrated agriculture-IYCF nutrition education programmes to help ensure better young child nutrition outcomes. © 2017 John Wiley & Sons Ltd.

Proposals for the mitigation of the environmental impact of clinical laboratories.

PubMed

Lopez, Joseph B; Badrick, Tony

Laboratories should be aware of the carbon footprint resulting from their activities and take steps to mitigate it as part of their societal responsibilities. Once committed to a mitigation programme, they should announce an environmental policy, secure the support of senior management, initiate documentation, institute a staff training programme, schedule environmental audits and appoint an environmental manager. Laboratories may aspire to be accredited to one of the standards for environmental management, such as the ISO 14000. As environmental and quality issues are linked, the improvement in the environmental management of an organisation will ultimately lead to improved quality system performance. Indeed, environmental management could conceivably come under overall quality management. Although there will be initial costs, good environmental practices can bring savings. Environmental improvement should be based on the 3R concept to reduce, reuse and recycle. Several policy initiatives may be introduced. These include a green purchasing policy for equipment, laboratory furniture and reagents as well as the management of packaging wastes. There are several ways to reduce energy, water usage and wastage. A reduction of test numbers and collection tubes should be attempted. Paper management involves all aspects of 3R. The recycling of solvents and general wastes should be practised where feasible. The construction new laboratories or renovations to existing ones are opportunities to make them more environmentally-friendly. The advocacy of policies to associates and the inclusion of environmentally-friendly conditions on contractors are integral parts of the programme.

Community mobilisation for prevention requires engagement with and buy in from those communities. In the Mexico state of Guerrero, unprecedented social violence related to the narcotics trade has eroded most community structures. A recent randomised controlled trial in 90 coastal communities achieved sufficient mobilisation to reduce conventional vector density indicators, self-reported dengue illness and serologically proved dengue virus infection. The Camino Verde intervention was a participatory research protocol promoting local discussion of baseline evidence and co-design of vector control solutions. Training of facilitators emphasised community authorship rather than trying to convince communities to do specific activities. Several discussion groups in each intervention community generated a loose and evolving prevention plan. Facilitators trained brigadistas, the first wave of whom received a small monthly stipend. Increasing numbers of volunteers joined the effort without pay. All communities opted to work with schoolchildren and for house-to-house visits by brigadístas. Children joined the neighbourhood vector control movements where security conditions permitted. After 6 months, a peer evaluation involved brigadista visits between intervention communities to review and to share progress. Although most communities had no active social institutions at the outset, local action planning using survey data provided a starting point for community authorship. Well-known in their own communities, brigadistas faced little security risk compared with the facilitators who visited the communities, or with governmental programmes. We believe the training focus on evidence-based dialogue and a plural community ownership through multiple design groups were key to success under challenging security conditions. ISRCTN27581154 .

Geo-Seas - a pan-European infrastructure for the management of marine geological and geophysical data.

Geo-Seas - a pan-European infrastructure for the management of marine geological and geophysical data. Helen Glaves1 and Colin Graham2 on behalf of the Geo-Seas consortium The Geo-Seas project will create a network of twenty six European marine geoscience data centres from seventeen coastal countries including six from the Baltic Sea area. This will be achieved through the development of a pan-European infrastructure for the exchange of marine geoscientific data. Researchers will be able to locate and access harmonised and federated marine geological and geophysical datasets and data products held by the data centres through the Geo-Seas data portal, using a common data catalogue. The new infrastructure, an expansion of the exisiting SeaDataNet, will create an infrastructure covering oceanographic and marine geoscientific data. New data products and services will be developed following consultations with users on their current and future research requirements. Common data standards will be implemented across all of the data centres and other geological and geophysical organisations will be encouraged to adopt the protocols, standards and tools which are developed as part of the Geo-Seas project. Oceanographic and marine data include a wide range of variables, an important category of which are the geological and geophysical data sets. This data includes raw observational and analytical data as well as derived data products from seabed sediment samples, boreholes, geophysical surveys (seismic, gravity etc) and sidescan sonar surveys. All of which are essential in order to produce a complete interpretation of seabed geology. Despite there being a large volume of geological and geophysical data available for the marine environment it is currently very difficult to use these datasets in an integrated way between organisations due to different nomenclatures, formats, scales and coordinate systems being used within different organisations and also within different countries. This makes the direct use of primary data in an integrated way very difficult and also hampers use of the data sets in a harmonised way to produce multidisciplinary data products and services. To ensure interoperability with other marine environmental data types Geo-Seas ISO19115 metadata, OGC and GeoSciML standards will be used as the basis for the metadata profiles for the geological and geophysical data. This will be largely achieved by modifying the SeaDataNet metadata standard profile (Common Data Index or CDI), which is itself based upon the ISO19115 standard, to accommodate the requirements of the Geo-Seas project. The overall objective of Geo-Seas project is to build and deploy a unified marine geoscientific data infrastructure within Europe which will in effect provide a data grid for the sharing of marine geological and geophysical data. This will result in a major improvement in the locating, accessing and delivery of federated marine geological and geophysical data and data products from national geological surveys and research institutes across Europe. There is an emphasis on interoperability both with other disciplines as well as with other key framework projects including the European Marine Observation and Data Network (EMODNet) and One Geology - Europe. In addition, a key objective of the Geo-Seas project is to underpin European directives such as INSPIRE as well as recent framework programmes on both the global and European scale, for example Global Earth Observation System of Systems (GEOSS) and Global Monitoring for Environment and Security (GMES), all of which are intended to encourage the exchange of data and information.

The Sentinel-6/Jason-CS mission will consist of 2 spacecraft and will be the latest in a series of ocean surface topography missions that will span nearly three decades. They follow the altimeters on- board TOPEX/Poseidon through to Jason-3 (expected March 2015). Jason-CS will continue to fulfil objectives of the reference series whilst introducing a major enhancement in capability providing the operational and science oceanographic community with the state of the art in terms of platform, measurement instrumentation design thus securing optimal operational and science data return. The programme is a part of the EC Copernicus initiative, whose objective is to support Europe's goals regarding sustainable development and global governance of the environment by providing timely and quality data, information, services and knowledge. The programme brings together: ESA for development, procurement & early orbit activities; EUMETSAT for mission management, ground segment, flight ops, contributing funding of the 1st satellite and participation in funding for the 2nd satellite; NASA for the US payload and launcher procurement in addition to funding US science opportunities; EC for funding the operations and participation in funding (with EUMETSAT) for the 2nd satellite; NOAA are expected to provide US ground stations & operations services; CNES for mission expertise and provision of the POD service. The consortium plan to procure 2 satellites with the 1st planned for launch readiness in the 1st half of 2020 with the 2nd satellite 5 years later. The first major commitment to funding was given by the ESA member states that approved the programme in June 2014 and in addition the European Commission funding is also fully secure. The design is based on a platform derived from CryoSat-2 adjusted to the specific requirements of the higher orbit. The principle payload instrument is a high precision Ku/C band radar altimeter with retrieval of geophysical parameters (surface elevation, wind speed and SWH) from the altimeter data require supporting measurements: a DORIS receiver for POD; The Climate Quality Advanced Microwave Radiometer (AMR-C) provided by JPL for high stability path delay correction. Orbit tracking data are also provided by GPS & LRA. An additional US GPS receiver, GNSS-RO, will be dedicated to radio-occultation.

Are patients deemed 'dangerous and severely personality disordered' different from other personality disordered patients detained in forensic settings?

In 1999, the UK government initiated a programme for the assessment and treatment of individuals deemed to have 'dangerous and severe personality disorder' (DSPD). After over 10 years of specialist service development, it is not clear whether DSPD patients represent a distinct group. The aim of this study was to establish whether people admitted to DSPD hospital units could be distinguished in presentation or personality traits from people with personality disorder admitted to standard secure hospital services. Thirty-eight men detained in high-security hospital DSPD units were compared with 62 men detained in conventional medium or high security hospital units, using the Psychopathy Checklist-Revised (PCL-R) and other standard personality disorder, clinical and offending measures. Compared with their counterparts in standard services, the DSPD group had higher scores on PCL-R psychopathy, significantly more convictions before age 18 years, greater severity of institutional violence and more prior crimes of sexual violence. Regression analysis confirmed that only PCL-R Factor 1, reflecting core interpersonal and affective features of psychopathy, predicted group membership. The DSPD group emerged as having higher psychopathy scores, but as there is currently no evidence that the core personality features of psychopathy are amenable to treatment, there is little justification for treating high-psychopathy forensic patients differently from those with other disorders of personality.

To assess how nurses' perception of their safety and risk of violence was affected by their work environment and whether this perception correlated with their actual risk. The work environment has an impact on nurses' perception of their risk of violence and this perception affects worker productivity, quality, employee retention, worker satisfaction and their actual safety. A cross-sectional survey was conducted in person of 314 emergency department nurses and 143 psychiatric nurses, and assault data was collected from injury logs. This study found that nurses in the emergency and psychiatric units differed in their perception of violence and safety. The workplace elements that led to a perception of lower risk of violence were not correlated with a lower rate of injury from violent acts. The nurses' beliefs about the adequacy of security equipment, security guards and the frequency of verbal abuse were strongly correlated with perceived safety. Several factors that influence nurses' perception of their risk of violence are not well correlated with their actual risk. Managers must address workplace elements that affect nurse perceptions because this has an impact on quality and employee retention. They must also address factors that have an impact on the actual risk of violence because this study showed, for the first time, that these may differ from perceptions. © 2012 Blackwell Publishing Ltd.

Use of an Infrared Thermometer with Laser Targeting in Morphological Scene Change Detection for Fire Detection

NASA Astrophysics Data System (ADS)

Tickle, Andrew J.; Singh, Harjap; Grindley, Josef E.

2013-06-01

Morphological Scene Change Detection (MSCD) is a process typically tasked at detecting relevant changes in a guarded environment for security applications. This can be implemented on a Field Programmable Gate Array (FPGA) by a combination of binary differences based around exclusive-OR (XOR) gates, mathematical morphology and a crucial threshold setting. This is a robust technique and can be applied many areas from leak detection to movement tracking, and further augmented to perform additional functions such as watermarking and facial detection. Fire is a severe problem, and in areas where traditional fire alarm systems are not installed or feasible, it may not be detected until it is too late. Shown here is a way of adapting the traditional Morphological Scene Change Detector (MSCD) with a temperature sensor so if both the temperature sensor and scene change detector are triggered, there is a high likelihood of fire present. Such a system would allow integration into autonomous mobile robots so that not only security patrols could be undertaken, but also fire detection.

The aim of this survey was to explore staff attitudes to the indoor smoking ban in a medium secure unit and to ascertain if they had experienced any difficulties in imposing the ban in the four months after its introduction. All staff members available on duty who agreed to participate in the survey were interviewed using a semi-structured questionnaire. The response rate was 65%. Sixty-four percent of the staff supported the smoking ban. Forty-three percent reported experiencing patient management problems with the majority complaining of increased patient aggression, increased use of staff time in supervising patients smoking. Additionally, supervising staff were still being exposed to passive smoking. Sixty-five percent reported positive effects due to the ban with the majority reporting that patients were sleeping at night due to the smoking area being closed at night. A significant proportion of the staff is still opposed to the smoking ban. Changing staff attitudes through educational programmes will be important in ensuring success of a possible future total ban in psychiatric units. 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Post-conflict reconstruction of the health system of Afghanistan: assisting in the rehabilitation of a provincial hospital--context and experience.

PubMed

Cook, Judith

2003-01-01

Over more than two decades of conflict, Afghanistan's health system came to depend heavily on assistance from donors and non-governmental organizations (NGOs). When the Taliban fell in November 2001 the health system was in a state of collapse; Afghanistan's health indicators were amongst the worst in the world. National Health Policy is to deliver an essential package of health services to the entire population. It is acknowledged that reconstruction of the health system will depend on donor financial support and NGO involvement in health programmes. An example is Médecins du Monde's involvement in health system rehabilitation in the Ghor province. Investing in health can contribute to peace, stability and political transition. Security, needed for reconstruction and for NGOs to continue their crucial work in health, has recently deteriorated in parts of Afghanistan. Joint Regional Teams to provide security to outlying areas have been announced by the US. There is concern that their proposed humanitarian and development role could compromise perception of the neutrality and impartiality of NGOs.

Computation of spanwise distribution of circulation and lift coefficient for flapped wings of arbitrary planform

NASA Technical Reports Server (NTRS)

Razak, K.

1980-01-01

The question of the effect of distribution and magnitude of spanwise circulation and shed vorticity from an airplane wing on the distribution pattern of agricultural products distributed from an airplane was studied. The first step in an analysis of this question is the determination of the actual distribution of lift along an airplane wing, from which the pattern of shed vorticity can be determined. A procedure is developed to calculate the span loading for flapped and unflapped wings of arbitrary aspect ratio and taper ratio. The procedure was programmed on a small programmable calculator, the Hewlett Packard HP-97, and also was programmed in BASIC language. They could be used to explore the variations in span loading that can be secured by variable flap deflections or the effect of flying at varying air speeds at different airplane gross weights. Either an absolute evaluation of span loading can be secured or comparative span loading can be evaluated to determine their effect on swath width and swath distribution pattern. The programs are intended to assist the user in evaluating the effect of a given spanload distribution.

An open forensic rehabilitation ward provides an important link bridging the gap between secure and community provisions. This paper provides an audit of such a service by examining the records of an open forensic rehabilitation ward over a five-year period from 1 June 2000 until 31 May 2005. During the audit period there were 51 admissions, involving 45 different patients, and 50 discharges. The majority of the patients came from secure unit facilities, acute psychiatric wards or home. Thirty-nine patients were discharged either into hostels (66%) or their home (12%). The majority of patients (80%) had on admission a primary diagnosis of either schizophrenia or schizoaffective disorder. Most had an extensive forensic history. The focus of their admission was to assess and treat their mental illness/disorder and offending behaviour and this was successful as the majority of patients were transferred to a community placement after a mean of 15 months. It is essential that there is a well-integrated care pathway for forensic patients, involving constructive liaison with generic services and a well-structured treatment programme which integrates the key principles of the 'recovery model' approach to care.

The United Nations and One Health: the International Health Regulations (2005) and global health security.

The One Health approach encompasses multiple themes and can be understood from many different perspectives. This paper expresses the viewpoint of those in charge of responding to public health events of international concern and, in particular, to outbreaks of zoonotic disease. Several international organisations are involved in responding to such outbreaks, including the United Nations (UN) and its technical agencies; principally, the Food and Agriculture Organization of the UN (FAO) and the World Health Organization (WHO); UN funds and programmes, such as the United Nations Development Programme, the World Food Programme, the United Nations Environment Programme, the United Nations Children's Fund; the UN-linked multilateral banking system (the World Bank and regional development banks); and partner organisations, such as the World Organisation for Animal Health (OIE). All of these organisations have benefited from the experiences gained during zoonotic disease outbreaks over the last decade, developing common approaches and mechanisms to foster good governance, promote policies that cut across different sectors, target investment more effectively and strengthen global and national capacities for dealing with emerging crises. Coordination among the various UN agencies and creating partnerships with related organisations have helped to improve disease surveillance in all countries, enabling more efficient detection of disease outbreaks and a faster response, greater transparency and stakeholder engagement and improved public health. The need to build more robust national public human and animal health systems, which are based on good governance and comply with the International Health Regulations (2005) and the international standards set by the OIE, prompted FAO, WHO and the OIE to join forces with the World Bank, to provide practical tools to help countries manage their zoonotic disease risks and develop adequate resources to prevent and control disease outbreaks, particularly at the animal source. All these efforts contribute to the One Health agenda.

Future Earth -- New Approaches to address Climate Change and Sustainability in the MENA Region

Interactions and feedbacks between rapidly increasing multiple pressures on water, energy and food security drive social-ecological systems at multiple scales towards critical thresholds in countries of the Eastern Mediterranean, the Middle East and North Africa (MENA Region). These pressures, including climate change, the growing demand on resources and resource degradation, urbanization and globalization, cause unprecedented challenges for countries and communities in the region. Responding to these challenges requires integrated science and a closer relationship with policy makers and stakeholders. Future Earth has been designed to respond to these urgent needs. In order to pursue such objectives, Future Earth is becoming the host organization for some 23 programs that were previously run under four global environmental change programmes, DIVERSITAS, the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme (IHDP) and the World Climate Research Programme (WCRP). Some further projects arose out of the Earth System Science Partnership (ESSP). It thus brings together a wide spectrum of expertise and knowledge that will be instrumental in tackling urgent problems in the MENA region and the wider Mediterranean Basin. Future Earth is being administered by a globally distributed secretariat that also includes a series of Regional Centers, which will be the nuclei for the development of new regional networks. The Cyprus Institute in Nicosia, Cyprus (CyI; www.cyi.ac.cy) is hosting the Regional Center for the MENA Region. The CyI is a non-profit research and post-graduate education institution with a strong scientific and technological orientation and a distinctive regional, Eastern Mediterranean scope. Cyprus at the crossroads of three continents and open to all nations in the region provides excellent conditions for advancing the research agenda of Future Earth in the MENA Region. Given the recent and ongoing major political and societal transformation in the region, research and development that help prepare the MENA countries for anticipated global changes and advance the development of sustainable structures are not only meaningful, but also a quite challenging undertakings.

Addressing sexual health behaviour during emerging adulthood: a critical review of the literature.

In this critical literature review, we examine evidence-based interventions that target sexual behaviours of 18- to 25-year-old emerging adult women. Nurses and clinicians implement theory-driven research programmes for young women with increased risk of HIV/AIDS and sexually transmitted infections. Strategies to decrease transmission of HIV and sexually transmitted infections are rigorously evaluated and promoted by public health agencies such as the United States Centers for Disease Control and Prevention. While many interventions demonstrate episodic reductions in sexual risk behaviours and infection transmission, there is little evidence they build sustainable skills and behaviours. Programmes may not attend to contextual and affective influences on sexual behaviour change. Discursive paper. We conducted a conceptually based literature review and critical analysis of the Centers for Disease Control and Prevention's best-evidence and good-evidence HIV behavioural interventions. In this review, we examined three contextual and affective influences on the sexual health of emerging adult women: (1) developmental age, (2) reproduction and pregnancy desires and (3) sexual security or emotional responses accompanying relationship experiences. Our analyses revealed intervention programmes paid little attention to ways age, desires for pregnancy or emotional factors influence sexual decisions. Some programmes included 18- to 25-year-olds, but they made up small percentages of the sample and did not attend to unique emerging adult experiences. Second, primary focus on infection prevention overshadowed participant desires for pregnancy. Third, few interventions considered emotional mechanisms derived from relationship experiences involved in sexual decision-making. Growing evidence demonstrates sexual health interventions may be more effective if augmented to attend to contextual and affective influences on relationship risks and decision-making. Modifying currently accepted strategies may enhance sustainability of sexual health-promoting behaviours. This study provides nurses and public health educators with recommendations for broadening the content of sexual health promotion intervention programming. © 2014 John Wiley & Sons Ltd.

The Norwegian immunisation register--SYSVAK.

The Norwegian immunisation register, SYSVAK, is a national electronic immunisation register. It became nationwide in 1995. The major aim was to register all vaccinations in the Childhood Immunisation Programme to ensure that all children are offered adequate vaccination according to schedule in the programme, and to secure high vaccination coverage. Notification to SYSVAK is mandatory, based on personal identification numbers. This allows follow up of individual vaccination schedules and linkage of SYSVAK data to other national health registers for information on outcome diagnoses, such as the surveillance system for communicable diseases. Information from SYSVAK is used to determine vaccine coverage in a timely manner. Coverage can be broken down to regional/local levels and used for active surveillance of vaccination coverage and decisions about interventions. During the 2009 influenza A(H1N1)pdm09 pandemic, an adaptation of SYSVAK enabled daily surveillance of vaccination coverage on national and regional levels. Currently, data from SYSVAK are used, among others, in studies on adverse events related to pandemic vaccination. Future challenges include maximising usage of collected data in surveillance and research, and continued improvement of data quality. Immunisation registers are rich sources for high quality surveillance of vaccination coverage, effectiveness, vaccine failure and adverse events, and gold mines for research.

2004-04-01

Ethernet passive optical network (EPON), which represents the convergence of low-cost, high-bandwidth and supporting multiple services, appears to be one of the best candidates for the next-generation access network. The work of standardizing EPON as a solution for access network is still underway in the IEEE802.3ah Ethernet in the first mile (EFM) task force. The final release is expected in 2004. Up to now, there has been no standard application specific integrated circuit (ASIC) chip available which fulfills the functions of media access control (MAC) layer of EPON. The MAC layer in EPON system has many functions, such as point-to-point emulation (P2PE), Ethernet MAC functionality, multi-point control protocol (MPCP), network operation, administration and maintenance (OAM) and link security. To implement those functions mentioned above, an embedded real-time operating system (RTOS) and a flexible programmable logic device (PLD) with an embedded processor are used. The software and hardware functions in MAC layer are realized through programming embedded microprocessor and field programmable gate array(FPGA). Finally, some experimental results are given in this paper. The method stated here can provide a valuable reference for developing EPON MAC layer ASIC.

Infectious disease ecology has recently raised its public profile beyond the scientific community due to the major threats that wildlife infections pose to biological conservation, animal welfare, human health and food security. As we start unravelling the full extent of emerging infectious diseases, there is an urgent need to facilitate multidisciplinary research in this area. Even though research in ecology has always had a strong theoretical component, cultural and technical hurdles often hamper direct collaboration between theoreticians and empiricists. Building upon our collective experience of multidisciplinary research and teaching in this area, we propose practical guidelines to help with effective integration among mathematical modelling, fieldwork and laboratory work. Modelling tools can be used at all steps of a field-based research programme, from the formulation of working hypotheses to field study design and data analysis. We illustrate our model-guided fieldwork framework with two case studies we have been conducting on wildlife infectious diseases: plague transmission in prairie dogs and lyssavirus dynamics in American and African bats. These demonstrate that mechanistic models, if properly integrated in research programmes, can provide a framework for holistic approaches to complex biological systems. PMID:22809422

This power considers the process of implementing clinical governance in primary care and its impact on quality improvement. It discuss how clinical governance is being implemented both at the level of Primary Care Organisations and general practices, and the challenges to implementing clinical governance. It also suggests a model for promoting the factors that will help clinical governance improve quality of care. The experience of implementing clinical governance is broadly positive to date. However, the government needs to match its commitment to a ten-year programme of change with realistic timetables to secure the cultural and organisational changes needed to improve quality of care.

To examine associations between food insecurity, excess body weight, psychosocial factors and food behaviours among low-income African-American families. Cross-sectional survey of participants in the baseline evaluation of the B'More Healthy Communities for Kids (BHCK) obesity prevention trial. We collected data on socio-economic factors, food source destinations, acquiring food, preparation methods, psychosocial factors, beliefs and attitudes, participation in food assistance programmes, anthropometry and food security. We used principal component analysis to identify patterns of food source destinations and logistic regression to examine associations. Fourteen low-income, predominantly African-American neighbourhoods in Baltimore City, MD, USA. Two hundred and ninety-eight adult caregiver-child (10-14 years old) dyads. Of households, 41·6 % had some level of food insecurity and 12·4 % experienced some level of hunger. Food-insecure participants with hunger were significantly more likely to be unemployed and to have lower incomes. We found high rates of excess body weight (overweight and obesity) among adults and children (82·8 % and 37·9 % among food insecure without hunger, 89·2 % and 45·9 % among food insecure with hunger, respectively), although there were no significant differences by food security status. Food source usage patterns, food acquisition, preparation, knowledge, self-efficacy and intentions did not differ by food security. Food security was associated with perceptions that healthy foods are affordable and convenient. Greater caregiver body satisfaction was associated with food insecurity and excess body weight. In this setting, obesity and food insecurity are major problems. For many food-insecure families, perceptions of healthy foods may serve as additional barriers to their purchase and consumption.

Why and How the Dairy Farmers of India are Vulnerable to the Impacts of Climate Variability and Change?

Climate change and variability has added many atrociousness to India's food security challenges and the relationship between the asset components of farmers and climate change is always complex. In India, dairy farming substantially contributes towards the food security and always plays a supportive role to agriculture from the adversities. This study provides an overview of the socio economic and livelihood vulnerability of small holder dairy farmers of India to climate change and variability in three dimensions — sensitivity, exposure and adaptive capacity by combining 70 indicators and 12 major components. The livelihood and socio economic vulnerability of dairy farmers to climate change and variability is assessed at taluka level in India through detailed house hold level data of livelihoods of Western Ghats region of India collected by several levels of survey and through Participatory Rural Appraisal (PRA) techniques from selected farmers complemented by thirty years of gridded weather data and other secondary data sources. The index score of dairy based livelihoods of Maharashtra was highly negative compared to other states with about 50 percent of farmers having high level of vulnerability with significant tradeoff between milk productivity and health, food, natural disasters-climate variability components. It finds that ensuring food security in the scenario of climate change will be a dreadful challenge and recommends identification of different potential options depending on local contexts at grass root level, the adoption of sustainable agricultural practices, focusing on improving the adaptive capacity component, provision of livelihood security, preparing the extensionists of Krishi Vigyan Kendras (KVKs)- universities to deal with the risks through extensive training programmes, long-term relief measures in the event of natural disasters, workshops on climate science and communication and promoting farmer centric extension system.

Perspectives from the frontlines: palliative care providers' expectations of Canada's compassionate care benefit programme.

2010-11-01

Recognising their valuable role as key informants, this study examines the perspectives of front-line palliative care providers (FLPCP) regarding a social benefit programme in Canada designed to support family caregivers at end-of-life, namely the Compassionate Care Benefit (CCB). The CCB's purpose is to provide income assistance and job security to family caregivers who take temporary leave from employment to care for a dying family member. Contributing to an evaluative study that aims to provide policy-relevant recommendations about the CCB, this analysis draws on semi-structured interviews undertaken in 2007/2008 with FLPCPs (n = 50) from across Canada. Although participants were not explicitly asked during interviews about their expectations of the CCB, thematic content analysis revealed 'expectations' as a key finding. Through participants' discussions of their knowledge of and familiarity with the CCB, specific expectations were identified and grouped into four categories: (1) temporal; (2) financial; (3) informational; and (4) administrative. Findings demonstrate that participants expect the CCB to provide: (1) an adequate length of leave time from work, which is reflective of the uncertain nature of caregiving at end-of-life; (2) adequate financial support; (3) information on the programme to be disseminated to FLPCPs so that they may share it with others; and (4) a simple, clear, and quick application process. FLPCPs hold unique expertise, and ultimately the power to shape uptake of the CCB. As such, their expectations of the CCB contribute valuable knowledge from which relevant policy recommendations can be made to better meet the needs of family caregivers and FLPCPs alike. © 2010 Blackwell Publishing Ltd.

Supply-side harm reduction strategies: Bolivia's experiment with social control.

PubMed

Farthing, Linda; Kohl, Benjamin

2012-11-01

Harm reduction approaches to drug control have almost exclusively focussed on consumers in northern countries. This article supports recent analysis that indicates that such policies also hold relevance for producer countries by drawing on recent policy innovations in Bolivia. When Evo Morales, the president of the national coca grower confederation, was elected the country's first indigenous president in 2005, he promised to fundamentally change 25 years of the U.S.-funded "drug war" that had generated repeated human rights violations. The new policy, which implicitly incorporates harm reduction principles combined with respect for human rights, recognizes coca leaf's traditional use and cultural importance and relies on vigorous local organizations to implement a community-based programme called social control. Results to date indicate that Bolivia's social control experience has reduced violence in coca growing communities, ensured small farmers a subsistence income from coca and increased sovereignty, while making a modest contribution to containing expansion of coca cultivation. The programme has registered 50,000 farmers who are allowed to cultivate limited quantities of coca to supply traditional users and helped them gain secure title to their land. This registration is combined with satellite surveillance to guarantee that farmers do not exceed limits established by law. To date, the programme's reach is incomplete and coca is still diverted to the drug trade. Nonetheless, the approach may offer lessons for other drug producer countries, particularly where strong socio-political organizations are found in combination with closeknit communities holding shared cultural values.

Bourne, Lesley T; Hendricks, Michael K; Marais, Debbie; Eley, Brian

2007-10-01

Despite various national nutrition and primary healthcare programmes being initiated in South Africa over the last decade, child health has deteriorated. This is seen by the rise in infant and child mortality rates, the high prevalence of preventable childhood diseases, e.g. diarrhoea and lower respiratory tract infections, and the coexistence of under-nutrition along with HIV/AIDS. Poor dietary intake, food insecurity and poor quality of basic services prevail within this precarious causal web. The national Integrated Nutrition Programme is a comprehensive nutrition strategy that focuses on children below 6 years old, at-risk pregnant and lactating women, and those affected by communicable and non-communicable diseases. Focus areas relevant to pre-school children include disease-specific nutrition treatment, support and counselling; growth monitoring and promotion (GMP); micronutrient malnutrition control; breastfeeding promotion, protection and support; contributions to household food security; nutrition interventions among HIV-infected children; and nutrition promotion, education and advocacy. Progress towards this includes the Baby-Friendly Hospital Initiative; mandatory fortification of maize meal and wheat flour with multiple micronutrients; vitamin A supplementation coverage and mandatory iodization of salt by legislation; the provision of free road-to-health charts for GMP; and the National School Nutrition Programme. Since 2003, the basis of the nutrition education strategy has been the locally developed food-based dietary guidelines (FBDGs), directed at adults and school-going children. This review sketches the backdrop to and motivation for the introduction of specifically targeted paediatric FBDGs, for mothers and caregivers of children from birth to age 7 years, as a national initiative.

The new NHS requires transformational leadership; people with the knowledge and motivation to make effective change combined with an understanding of the system they work in. The aim of the Practice Leaders' Programme (PLP) is to generate the conditions needed to focus the energy and collaborative creativity required for innovation to enhance leadership skills across the health economy improving patient care. The PLP engaged 60 local leaders from central England in a new approach enabling them to influence others. It has informed educational policy and practice and helped change professional behaviours. Each participant implemented improvements in care and participated in six action learning sets (ALS) and up to six coaching sessions. Evidence of progress, learning and impact was identified in project reports, reflective diaries and evaluations. The ALS brought together key individuals from clinical and management disciplines across a diverse organisation to redesign a system by developing a shared vision for improving the quality of patient care. The links forged, the projects initiated, and the skills cultivated through the PLP produced ongoing benefits and outcomes beyond the course itself. Coaching sessions helped participants focus their efforts to achieve maximum impact and to become resilient in managing service change effectively. The programme has evolved over four years, building on recommendations from external evaluation which identified statistically significant increases in leadership competences. Further enhancement of this programme secured an International Health Improvement Award. Three key findings of positive impact have emerged; personal growth, service improvement, and legacy and sustainability.

Rheumatic heart disease (RHD) remains a major disease burden in low-resource settings globally. Patient registers have long been recognised to be an essential instrument in RHD control and elimination programmes, yet to date rely heavily on paper-based data collection and non-networked data-management systems, which limit their functionality. To assess the feasibility and potential benefits of producing an electronic RHD patient register. We developed an eRegister based on the World Heart Federation's framework for RHD patient registers using CommCare, an open-source, cloud-based software for health programmes that supports the development of customised data capture using mobile devices. The resulting eRegistry application allows for simultaneous data collection and entry by field workers using mobile devices, and by providers using computer terminals in clinics and hospitals. Data are extracted from CommCare and are securely uploaded into a cloud-based database that matches the criteria established by the WHF framework. The application can easily be tailored to local needs by modifying existing variables or adding new ones. Compared with traditional paper-based data-collection systems, the eRegister reduces the risk of data error, synchronises in real-time, improves clinical operations and supports management of field team operations. The user-friendly eRegister is a low-cost, mobile, compatible platform for RHD treatment and prevention programmes based on materials sanctioned by the World Heart Federation.

Abstract Objective To identify how 10 low- and middle-income countries achieved accelerated progress, ahead of comparable countries, towards meeting millennium development goals 4 and 5A to reduce child and maternal mortality. Methods We synthesized findings from multistakeholder dialogues and country policy reports conducted previously for the Success Factors studies in 10 countries: Bangladesh, Cambodia, China, Egypt, Ethiopia, the Lao People's Democratic Republic, Nepal, Peru, Rwanda and Viet Nam. A framework approach was used to analyse and synthesize the data from the country reports, resulting in descriptive or explanatory conclusions by theme. Findings Successful policy and programme approaches were categorized in four strategic areas: leadership and multistakeholder partnerships; health sector; sectors outside health; and accountability for resources and results. Consistent and coordinated inputs across sectors, based on high-impact interventions, were assessed. Within the health sector, key policy and programme strategies included defining standards, collecting and using data, improving financial protection, and improving the availability and quality of services. Outside the health sector, strategies included investing in girls’ education, water, sanitation and hygiene, poverty reduction, nutrition and food security, and infrastructure development. Countries improved accountability by strengthening and using data systems for planning and evaluating progress. Conclusion Reducing maternal and child mortality in the 10 fast-track countries can be linked to consistent and coordinated policy and programme inputs across health and other sectors. The approaches used by successful countries have relevance to other countries looking to scale-up or accelerate progress towards the sustainable development goals. PMID:27147765

Gait restoration is an integral part of rehabilitation of brain lesioned patients. Modern concepts favour a task-specific repetitive approach, i.e. who wants to regain walking has to walk, while tone-inhibiting and gait preparatory manoeuvres had dominated therapy before. Following the first mobilization out of the bed, the wheelchair-bound patient should have the possibility to practise complex gait cycles as soon as possible. Steps in this direction were treadmill training with partial body weight support and most recently gait machines enabling the repetitive training of even surface gait and even of stair climbing. With treadmill training harness-secured and partially relieved wheelchair-mobilised patients could practise up to 1000 steps per session for the first time. Controlled trials in stroke and SCI patients, however, failed to show a superior result when compared to walking exercise on the floor. Most likely explanation was the effort for the therapists, e.g. manually setting the paretic limbs during the swing phase resulting in a too little gait intensity. The next steps were gait machines, either consisting of a powered exoskeleton and a treadmill (Lokomat, AutoAmbulator) or an electromechanical solution with the harness secured patient placed on movable foot plates (Gait Trainer GT I). For the latter, a large multi-centre trial with 155 non-ambulatory stroke patients (DEGAS) revealed a superior gait ability and competence in basic activities of living in the experimental group. The HapticWalker continued the end effector concept of movable foot plates, now fully programmable and equipped with 6 DOF force sensors. This device for the first time enables training of arbitrary walking situations, hence not only the simulation of floor walking but also for example of stair climbing and perturbations. Locomotor therapy is a fascinating new tool in rehabilitation, which is in line with modern principles of motor relearning promoting a task-specific repetitive approach. Sophisticated technical developments and positive randomized controlled trials form the basis of a growing acceptance worldwide to the benefits or our patients.

The Americas are extremely important as a unique contributor to Food Security. It provides from tropical to temperate crops. Not only they are able to feed their own population, but contribute significantly to the food supply of the population in developed, emergent and underdeveloped countries. This fact has given the region a unique responsibility to develop a regional risk-management strategy to manage food insecurity at a local, national, regional and global level. Although international agencies such as UN Food and Agriculture Organization (FAO), Instituto Interamericano para la Cooperación en Agricultura (IICA) and the regional centres of the Consultative Group for International Agriculture Research (CGIAR) and the World Bank (WB), are engaged in actions for Risk Management in Agriculture for reducing Food Insecurity. However there is a need to build a framework and/or comprehensive regional strategy for the Americas. It would identify areas for promoting research projects where natural and social science work together for producing relevant scientific information and tools i.e. maps, indicators, models and scenarios, early warning systems, etc. to cooperate with both policy and decision makers in the public and private sectors. This would eventually lead to a comprehensive regional programme for reducing food insecurity. The purpose of International Council for Science-International Research and the International Research for Disaster Risk programme (ICSU-IRDR) and ICSU Regional Office for Latinamerica and the Caribbean (ICSU-ROLAC) is to promote the cooperation of the relevant scientific fields in both natural science and social science in a multi and trans-disciplinary approach on risk management to reduce food insecurity. Also both ICSU-IRDR and ICSU-ROLAC are building a case for the inclusion of the scientific community in the revision of the Hjogo Framework for Action for Disaster Reduction to be held in 2015 as risk management for reducing food insecurity is part of the agenda.

To investigate how the erector spinae (ES) and gluteus maximus (GM) muscle activity and the anterior pelvic tilt angle change with different hip abduction angles during a bridging exercise. Twenty healthy participants (10 males and 10 females, aged 21.6 ± 1.6) voluntarily participated in this study. Surface electromyography (EMG) signals were recorded from the ES and GM during bridging at three hip abduction angles: 0°, 15°, and 30°. Simultaneously, the anterior pelvic tilt angle was measured using Image J software. The EMG amplitude of the GM muscle and the GM/ES EMG ratio were greatest at 30° hip abduction, followed by 15° and then 0° hip abduction during the bridging exercise. In contrast, the ES EMG amplitude at 30° hip abduction was significantly lesser than that at 0° and 15° abduction. Additionally, the anterior pelvic tilt angle was significantly lower at 30° hip abduction than at 0° or 15°. Bridging with 30° hip abduction can be recommended as an effective method to selectively facilitate GM muscle activity, minimize compensatory ES muscle activity, and decrease the anterior pelvic tilt angle.

Arson and fire-setting are highly prevalent among patients in secure psychiatric settings but there is an absence of valid and reliable assessment instruments and no evidence of a significant approach to intervention. To develop a semi-structured interview assessment specifically for fire-setting to augment structured assessments of risk and need. The extant literature was used to frame interview questions relating to the antecedents, behaviour and consequences necessary to formulate a functional analysis. Questions also covered readiness to change, fire-setting self-efficacy, the probability of future fire-setting, barriers to change, and understanding of fire-setting behaviour. The assessment concludes with indications for assessment and a treatment action plan. The inventory was piloted with a sample of women in secure care and was assessed for comprehensibility, reliability and validity. Staff rated the St Andrews Fire and Risk Instrument (SAFARI) as acceptable to patients and easy to administer. SAFARI was found to be comprehensible by over 95% of the general population, to have good acceptance, high internal reliability, substantial test-retest reliability and validity. SAFARI helps to provide a clear explanation of fire-setting in terms of the complex interplay of antecedents and consequences and facilitates the design of an individually tailored treatment programme in sympathy with a cognitive-behavioural approach. Further studies are needed to verify the reliability and validity of SAFARI with male populations and across settings.

An Anti-Electromagnetic Attack PUF Based on a Configurable Ring Oscillator for Wireless Sensor Networks

2017-01-01

Wireless sensor networks (WSNs) are an emerging technology employed in some crucial applications. However, limited resources and physical exposure to attackers make security a challenging issue for a WSN. Ring oscillator-based physical unclonable function (RO PUF) is a potential option to protect the security of sensor nodes because it is able to generate random responses efficiently for a key extraction mechanism, which prevents the non-volatile memory from storing secret keys. In order to deploy RO PUF in a WSN, hardware efficiency, randomness, uniqueness, and reliability should be taken into account. Besides, the resistance to electromagnetic (EM) analysis attack is important to guarantee the security of RO PUF itself. In this paper, we propose a novel architecture of configurable RO PUF based on exclusive-or (XOR) gates. First, it dramatically increases the hardware efficiency compared with other types of RO PUFs. Second, it mitigates the vulnerability to EM analysis attack by placing the adjacent RO arrays in accordance with the cosine wave and sine wave so that the frequency of each RO cannot be detected. We implement our proposal in XINLINX A-7 field programmable gate arrays (FPGAs) and conduct a set of experiments to evaluate the quality of the responses. The results show that responses pass the National Institute of Standards and Technology (NIST) statistical test and have good uniqueness and reliability under different environments. Therefore, the proposed configurable RO PUF is suitable to establish a key extraction mechanism in a WSN. PMID:28914756

[Reality of healthcare access for migrant children in Mayotte].

The implementation of the social security system in 2005 in Mayotte has resulted in the end of free healthcare for all non-affiliated residents, primarily Comorians, due to the absence of the State Medical Aid (AME) in this department. Doctors of the World France opened a paediatric clinic in December 2009. The sociomedical data were collected during 5286 consultations in 2010. Analysis of these data demonstrates a link between access to healthcare for children and the residential status of their parents. The analysis concerns 2,350 patients met during consultations held by Doctors of the World France in Mayotte in 2010. The data have been electronically recorded and analysed by the Sphinx software. The results show that there are several obstacles to healthcare resulting in non-attendance. This situation is made worse if one of the parents has an irregular residential status and all the more so if both the parents have an irregular status. Affiliation to the social security system, however, improves the situation. The results show a delay in accessing healthcare, a poor vaccination programme and disturbing data on severe acute malnutrition. The specific healthcare measures in Mayotte do not respect the International Convention on the Rights of the Child. Direct affiliation to the social security system for children would entail a reduction in health insecurity for the children of parents with irregular residential status. It would also be necessary to reduce the factors that provoke fear of displacement, which would facilitate physical access to consultations.

Functional national laboratory networks and systems are indispensable to the achievement of global health security targets according to the International Health Regulations. The lack of indicators to measure the functionality of national laboratory network has limited the efficiency of past and current interventions to enhance laboratory capacity in resource-limited-settings. We have developed a matrix for the assessment of national laboratory network functionality and progress thereof, with support from the African Society of Laboratory Medicine and the Association of Public Health Laboratories. The laboratory network (LABNET) scorecard was designed to: (1) Measure the status of nine overarching core capabilities of laboratory network required to achieve global health security targets, as recommended by the main normative standards; (2) Complement the World Health Organization joint external evaluation tool for the assessment of health system preparedness to International Health Regulations (2005) by providing detailed information on laboratory systems; and (3) Serve as a clear roadmap to guide the stepwise implementation of laboratory capability to prevent, detect and act upon infectious threats. The application of the LABNET scorecard under the coordination of the African Society of Laboratory Medicine and the Association of Public Health Laboratories could contribute to the design, monitoring and evaluation of upcoming Global Health Security Agenda-supported laboratory capacity building programmes in sub Saharan-Africa and other resource-limited settings, and inform the development of national laboratory policies and strategic plans. Endorsement by the World Health Organization Regional Office for Africa is foreseen.

Due to the quick advancements in the personal communications systems and wireless communications, giving data security has turned into a more essential subject. This security idea turns into a more confounded subject when next-generation system requirements and constant calculation speed are considered in real-time. Hash functions are among the most essential cryptographic primitives and utilized as a part of the many fields of signature authentication and communication integrity. These functions are utilized to acquire a settled size unique fingerprint or hash value of an arbitrary length of message. In this paper, Secure Hash Algorithms (SHA) of types SHA-1, SHA-2 (SHA-224, SHA-256) and SHA-3 (BLAKE) are implemented on Field-Programmable Gate Array (FPGA) in a processor structure. The design is described and implemented using a hardware description language, namely VHSIC “Very High Speed Integrated Circuit” Hardware Description Language (VHDL). Since the logical operation of the hash types of (SHA-1, SHA-224, SHA-256 and SHA-3) are 32-bits, so a Superscalar Hash Microprocessor without Interlocked Pipelines (MIPS) processor are designed with only few instructions that were required in invoking the desired Hash algorithms, when the four types of hash algorithms executed sequentially using the designed processor, the total time required equal to approximately 342 us, with a throughput of 4.8 Mbps while the required to execute the same four hash algorithms using the designed four-way superscalar is reduced to 237 us with improved the throughput to 5.1 Mbps.

Achieving household nutrition security in societies in transition: an overview.

PubMed

Gopalan, C

2001-01-01

The achievement of nutrition security at the household level involves adequacy of food supply at the national level and equitable distribution of food among the population in accordance with their physiological needs. The emergence of globalization and market liberalization and the increasing power of some transnational corporations that are advocating pharmaceutical shortcuts have raised concerns in many developing countries. In order to achieve adequacy of food production, earlier mistakes (such as a reliance on unsustainable new technologies) need to be corrected and the resultant imbalances with respect to food production need to be reversed. Emerging new technologies, including genetic modifications, need to be effectively harnessed and adapted with due consideration to safety and sustainability. There is a need to collect convincing evidence of the efficacy and safety of genetically modified foods before they can gain general public acceptance. Information technology will play an important role in future programmes of food production and developing countries must strive to achieve access to this technology. There is considerable scope and need for the expansion of agro-based industries in villages and townships. This could create job opportunities and could also lead to better production and more effective utilization of local food resources by the community and reduce the present considerable loss of perishable food items. Household nutrition security means more than avoidance of chronic starvation. Policy makers of developing countries should set, as their target in the next century, the achievement of adequate nutrition rather than mere survival.

Cash-based transfer programmes are an emerging strategy in the prevention of wasting in children, especially targeted at vulnerable households during periods of food insecurity or during emergencies. However, the evidence surrounding the use of either cash or voucher transfer programmes in the humanitarian context and on nutritional outcomes is elusive. More evidence is needed not only to inform the global community of practice on best practices in humanitarian settings, but also to help strengthen national mitigation responses. The Research for Food Assistance on Nutrition Impact Pakistan study (REFANI-P) sets out to evaluate the impact of three cash-based interventions on nutritional outcomes in children aged less than five years from poor and very poor households in Dadu District. This four-arm parallel cluster randomised controlled trial is set among Action Against Hunger (ACF) programme villages in Dadu District, Sindh Province. Mothers are the target recipients of either seasonal unconditional cash transfers or fresh food vouchers. A comparison group receives 'standard care' provided by the ACF programme to which all groups have the same access. The primary outcomes are prevalence of wasting and mean weight-for-height Z-score (WHZ) in children. Impact will be assessed at 6 months and at 1 year from baseline. Using a theory-based approach we will determine 'how' the different interventions work by looking at the processes involved and the impact pathways following the theory of change developed for this context. Quantitative and qualitative data are collected on morbidity, health seeking, hygiene and nutrition behaviours, dietary diversity, haemoglobin concentration, women's empowerment, household food security and expenditures and social capital. The direct and indirect costs of each intervention borne by the implementing organisation and their partners as well as by beneficiaries and their communities are also assessed. The results of this trial will provide robust evidence to help increase knowledge about the predictability of how different modalities of cash-based transfer work best to reduce the risk of child wasting during a season where food insecurity is at its highest. Evidence on costing and cost-effectiveness will further aid decisions on choice of modality in terms of effectiveness and sustainability. Current Controlled Trials ISRCTN10761532 .

MyOcean is a three-year project (2008-2011) which goal is the development and pre-operational validation of the GMES Marine Core Service for ocean monitoring and forecasting. It's a transition project that will conduct the European "operational oceanography" community towards the operational phase of a GMES European service, which demands more European integration, more operationality, and more service. Observations, model-based data, and added-value products will be generated - and enhanced thanks to dedicated expertise - by the following production units: • Five Thematic Assembly Centers, each of them dealing with a specific set of observation data: Sea Level, Ocean colour, Sea Surface Temperature, Sea Ice & Wind, and In Situ data, • Seven Monitoring and Forecasting Centers to serve the Global Ocean, the Arctic area, the Baltic Sea, the Atlantic North-West shelves area, the Atlantic Iberian-Biscay-Ireland area, the Mediterranean Sea and the Black sea. Intermediate and final users will discover, view and get the products by means of a central web desk, a central re-active manned service desk and thematic experts distributed across Europe. The MyOcean Information System (MIS) is considering the various aspects of an interoperable - federated information system. Data models support data and computer systems by providing the definition and format of data. The possibility of including the information in the data file is depending on data model adopted. In general there is little effort in the actual project to develop a ‘generic' data model. A strong push to develop a common model is provided by the EU Directive INSPIRE. At present, there is no single de-facto data format for storing observational data. Data formats are still evolving, with their underlying data models moving towards the concept of Feature Types based on ISO/TC211 standards. For example, Unidata are developing the Common Data Model that can represent scientific data types such as point, trajectory, station, grid, etc., which will be implemented in netCDF format. SeaDataNet is recommending ODV and NetCDF formats. Another problem related to data curation and interoperability is the possibility to use common vocabularies. Common vocabularies are developed in many international initiatives, such as GEMET (promoted by INSPIRE as a multilingual thesaurus), UNIDATA, SeaDataNet, Marine Metadata Initiative (MMI). MIS is considering the SeaDataNet vocabulary as a base for interoperability. Four layers of different abstraction levels of interoperability an be defined: - Technical/basic: this layer is implemented at each TAC or MFC through internet connection and basic services for data transfer and browsing (e.g FTP, HTTP, etc). - Syntactic: allowing the interchange of metadata and protocol elements. This layer corresponds to a definition Core Metadata Set, the format of exchange/delivery for the data and associated metadata and possible software. This layer is implemented by the DIAL-P logical interface (e.g. adoption of INSPIRE compliant metadata set and common data formats). - Functional/pragmatic: based on a common set of functional primitives or on a common set of service definitions. This layer refers to the definition of services based on Web services standards. This layer is implemented by the DIAL-P logical interface (e.g. adoption of INSPIRE compliant network services). - Semantic: allowing to access similar classes of objects and services across multiple sites, with multilinguality of content as one specific aspect. This layer corresponds to MIS interface, terminology and thesaurus. Given the above requirements, the proposed solution is a federation of systems, where the individual participants are self-contained autonomous systems, but together form a consistent wider picture. A mid-tier integration layer mediates between existing systems, adapting their data and service model schema to the MIS. The developed MIS is a read-only system, i.e. does not allow updating (or inserting) data into the participant resource systems. The main advantages of the proposed approach are: • to enable information sources to join the MIS and publish their data and metadata in a secure way, without any modification to their existing resources and procedures and without any restriction to their autonomy; • to enable users to browse and query the MIS, receiving an aggregated result incorporating relevant data and metadata from across different sources; • to accommodate the growth of such a MIS, either in terms of its clients or of its information resources, as well as the evolution of the underlying data model.

Building a Continental Scale Land Cover Monitoring Framework for Australia

2012-04-01

Land cover information is critical for national reporting and decision making in Australia. A review of information requirements for reporting on national environmental indicators identified the need for consistent land cover information to be compared against a baseline. A Dynamic Land Cover Dataset (DLCD) for Australia has been developed by Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences (ABARES) recently, to provide a comprehensive and consistent land cover information baseline to enable monitoring and reporting for sustainable farming practices, water resource management, soil erosion, and forests at national and regional scales. The DLCD was produced from the analysis of Enhanced Vegetation Index (EVI) data at 250-metre resolution derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the period from 2000 to 2008. The EVI time series data for each pixel was modelled as 12 coefficients based on the statistical, phenological and seasonal characteristics. The time series were then clustered in coefficients spaces and labelled using ancillary information on vegetation and land use at the catchment scale. The accuracy of the DLCD was assessed using field survey data over 25,000 locations provided by vegetation and land management agencies in State and Territory jurisdictions, and by ABARES. The DLCD is seen as the first in a series of steps to build a framework for national land cover monitoring in Australia. A robust methodology to provide annual updates to the DLCD is currently being developed at Geoscience Australia. There is also a growing demand from the user community for land cover information at better spatial resolution than currently available through the DLCD. Global land cover mapping initiatives that rely on Earth observation data offer many opportunities for national and international programs to work in concert and deliver better outcomes by streamlining efforts on development and validation of land cover products. Among the upcoming missions, the Global Monitoring for Environment and Security (GMES) Sentinel-2 satellites are seen as an important source of optical data for updating land cover information in Australia. This paper outlines the DLCD development, key applications that inform nationally significant issues, further work on updating the DLCD that would enable transition to a national land cover monitoring framework, challenges and approaches to delivering land cover information at higher spatial resolutions on a continental scale, and the potential value of data from the Sentinel-2 mission in supporting land cover monitoring in Australia and globally.

: For Arianespace, the success of a launch service has always been the top priority. In 2002, the predicted number of flights is very high and we are ready to serve properly the customers as usual. Major steps will be achieved: the consumption of most of the Ariane 4, the first "Ariane 5 10 tons" flight and last, but first of all, the ENVISAT mission on flight V145 have a specific importance. Like many other ESA missions, ENVISAT mission has really been a great challenge. In fact, for almost 10 years, ESA and Arianespace have acted the complete compatibility between the spacecraft and the launcher. As the biggest and heaviest payload ever carried by Ariane, it has been design to fit the new European rocket. Based on the former PPF plateform, it occupies itself the place inside the highest fairing of Ariane 5. With approximately 8.2 metric tons and 10m high, this bird concentrates advanced technologies and will deliver a huge amount of datas. His time has come with 10 onboard scientific experiments to participate in a better understanding of the earth systemic behaviour and future. As never before, computer models will be precisely tuned and will serve differenciate global scenarii which predict future tendencies. As part of the ambitious European GMES (Global Monitoring for Environment and Security) initiative, ENVISAT, ERS, Meteosat or SPOT will contribute to the maximum extent possible. It took nearly 2 months for the complete set of 420 tons of equipments to reach the "Centre Spatial Guyanais" (CSG) using "MN Toucan" Ariane boat, or planes like Antonov or B747-Cargo. Then the payload campaign itself begun on May, the 17th 2001. Unpredicted shorten Ariane 5 mission on july, the 12th 2001, delayed ENVISAT flight to 2002, and gave the campaign a longer and unusual duration. Launcher and customer's teams adapted perfectly and coordinated until the launch. The ENVISAT campaign can be devided in 3 major periods. First period is the customer installation where huge plateforms and tools have been deployed. Then the payload integration itself have been achieved and concluded by fueling and pressurization. At the end, starting from february the 16th, vehicle and payload operations are definitely synchronized during the "Combined Operation Plan" (POC) period which lead to the "lift-off" and the deployment of the payload. The complete success of the mission during the flawless Ariane 5 flight on february, the 28th 2002, confirms that Europe as a all is structured to cope with any ambitious challenge.

Data from 8 different payloads orbiting on 14 satellite platforms (SEVIRI on-board MSG-1, -2 and -3, MODIS on-board Terra and Aqua, GOME-2 and IASI onboard MetOp-A, OMI on-board Aura, Cosmo-SkyMED/1, /2, /3 and /4, JAMI on-board MTSAT-1 and -2, and, until April 8th2012, SCHIAMACHY on-board ENVISAT) acquired at 5 different down-link stations, are disseminated to and automatically processed at 6 locations in 4 countries. The results are sent, in four separate geographic data streams (high-temperature thermal anomalies, volcanic Sulfur dioxide daily fluxes, volcanic ash and ground deformation), to a central facility called VVO, the 'Virtual Volcano Observatory'. This system operates 24H/24-7D/7 since September 2011 on all volcanoes in Europe, Africa, the Lesser Antilles, and the oceans around them, and during this interval has detected, measured and monitored all subaerial eruptions occurred in this region (44 over 45 certified, with overall detection and processing efficiency of ~97%). EVOSS borne realtime information is delivered to a group of 14 qualified end users, bearing the direct or indirect responsibility of monitoring and managing volcano emergencies, and of advising governments in Comoros, DR Congo, Djibouti, Ethiopia, Montserrat, Uganda, Tanzania, France and Iceland. We present the full set of eruptions detected and monitored - from 2004 to present - by multispectral payloads SEVIRI onboard the geostationary platforms of the MSG constellation, for developing and fine tuning-up the EVOSS system along with its real-time, pre- and post-processing automated algorithms. The set includes 91% of subaerial eruptions occurred at 15 volcanoes (Piton de la Fournaise, Karthala, Jebel al Tair, Erta Ale, Manda Hararo, Dalafilla, Nabro, Ol Doinyo Lengai, Nyiamulagira, Nyiragongo, Etna, Stromboli, Eyjafjallajökull, Grimsvötn, Soufriere Hills) showing radiant fluxes above ~0.5 GW and/or SO2 columns in excess of ~6 DU. Porting of automated thermal algorithms on MTSAT's JAMI (orbiting at 145°E) was developed on the eruptions of Merapi, Semeru Kliuchevskoi, Bezymianny and Shiveluch in 2006-2007, calibrated on the frequent activity of Batu Tara, and demonstrated on the 2012-2013 large eruption of Tolbachik.

A speed enhanced space variant correlation filer which has been designed to be invariant to change in orientation and scale of the target object but also to be spatially variant, i.e. the filter function becoming dependant on local clutter conditions within the image. The speed enhancement of the filter is due to the use of optimization techniques employing low-pass filtering to restrict kernel movement to be within regions of interest. The detection and subsequent identification capability of the two-stage process has been evaluated in highly cluttered backgrounds using both visible and thermal imagery acquired from civil and defense domains along with associated training data sets for target detection and classification. In this paper a series of tests have been conducted in multiple scenarios relating to situations that pose a security threat. Performance matrices comprised of peak-to-correlation energy (PCE) and peak-to-side lobe ratio (PSR) measurements of the correlation output have been calculated to allow the definition of a recognition criterion. The hardware implementation of the system has been discussed in terms of Field Programmable Gate Array (FPGA) chipsets with implementation bottle necks and their solution being considered.

Responding to the needs of children in crisis.

PubMed

Jones, Lynne

2008-06-01

This paper explores the issues confronting service providers setting up child and family mental health programmes in conflict, post conflict and disaster areas. Drawing on clinical experience and research in humanitarian settings, it calls for greater attention to the child's perspective, their individuality and the cultural, social and political context in which they live. It argues that those concerned with the psychopathology of children in crises should widen their frame of reference beyond narrowly defined traumatic reactions to include other mental health and psychosocial issues, including the current problems of daily life and the needs of children with pre-existing psychiatric disorders. It recommends culturally valid means of assessment, the creation of age-appropriate services and training for primary healthcare workers. Children's mental health needs in crises are varied, complex and intimately connected with their needs for security, food, shelter, education and family connection. This requires holistic, rights-based approaches that can access resources to address basic needs, advocate for security and protection, and recognize and address the needs of the more vulnerable children. This is the approach recommended by the Inter Agency Standing Committee Guidelines for Mental health and Psychosocial Support in Emergency Settings.

Challenges in Achieving Food Security in India

PubMed Central

Upadhyay, R Prakash; Palanivel, C

2011-01-01

First Millennium Development Goal states the target of “Halving hunger by 2015”. Sadly, the recent statistics for India present a very gloomy picture. India currently has the largest number of undernourished people in the world and this is in spite of the fact that it has made substantial progress in health determinants over the past decades and ranks second worldwide in farm output. The causes of existing food insecurity can be better viewed under three concepts namely the: ‘traditional concept’ which includes factors such as unavailability of food and poor purchasing capacity; ‘socio-demographic concept’ which includes illiteracy, unemployment, overcrowding, poor environmental conditions and gender bias; ‘politico-developmental concept’ comprising of factors such as lack of intersectoral coordination and political will, poorly monitored nutritional programmes and inadequate public food distribution system. If the Millennium Development Goal is to be achieved by 2015, efforts to improve food and nutrition security have to increase considerably. Priority has to be assigned to agriculture and rural development along with promoting women empowerment, ensuring sustainable employment and improving environmental conditions (water, sanitation and hygiene). As the problem is multi-factorial, so the solution needs to be multi-sectoral. PMID:23113100

Telemedicine systems and telecommunications.

Harnett, Brett

2006-01-01

Successful telemedicine requires appropriate equipment and some kind of telecommunications medium. However, successful telemedicine requires more than just technology. The three essential components are the personnel, the technology and a liberal measure of perseverance. Before the technology can be selected, it is necessary to consider the nature of the information to be transmitted between the sites and the time frame over which it must be sent to achieve the desired clinical goals, because this will determine the choice of equipment and the telecommunications network. Factors to be considered include the types of information to be transmitted, the quantity of information to be transferred, and security and privacy (e.g. in Europe and the USA there has been recent legislation about data security). The choice of transmission method for any telemedicine application is, in practice, a compromise between what one would like and what one can afford. In practice, various trade-offs have to be made, which include cost, availability of the service (i.e. the coverage), bandwidth, reliability and quality of service. Equipment and the telecommunications medium are a necessary, but not sufficient, pre-requisite for a successful telemedicine programme. The right people are also required and they must be properly trained.

Consequences of infertility in developing countries.

PubMed

Rouchou, Brittany

2013-05-01

Infertility affects more than 10% of the world's population. In developing countries, there are severe social, psychological and economic consequences for infertile men and women. All of the cited references are compiled from primary peer-reviewed research articles that were conducted through one-to-one interviews or focus groups in countries of developing regions, such as Africa, Asia and the Middle East. The following paper seeks to raise awareness of the consequences of infertility in developing nations and identify infertility as an under-observed, but significant public health issue. It is proposed that education programmes tailored to each society's specific religious beliefs and grounded traditions must be implemented in order to reverse the social stigma, detrimental psychological effects, and loss of economic security that results from infertility.

Verification of Triple Modular Redundancy (TMR) Insertion for Reliable and Trusted Systems

Berg, Melanie; LaBel, Kenneth A.

2016-01-01

We propose a method for TMR insertion verification that satisfies the process for reliable and trusted systems. If a system is expected to be protected using TMR, improper insertion can jeopardize the reliability and security of the system. Due to the complexity of the verification process, there are currently no available techniques that can provide complete and reliable confirmation of TMR insertion. This manuscript addresses the challenge of confirming that TMR has been inserted without corruption of functionality and with correct application of the expected TMR topology. The proposed verification method combines the usage of existing formal analysis tools with a novel search-detect-and-verify tool.

The purpose of the Women's Roundtable was to provide a forum for regional analysis of women workers, labor migration and trade policies, women's livelihoods, food security and social development, globalization, and adverse impacts of economic recession and inflation. Among the recommendations of the forum were that the impact of globalization on women should be monitored and that the analyses and concerns raised during the roundtable discussions should be disseminated through other regional and international platforms.

EPANET Multi-Species Extension Software and User's Manual ...

EPA Pesticide Factsheets

Software and User's Manual EPANET is used in homeland security research to model contamination threats to water systems. Historically, EPANET has been limited to tracking the dynamics of a single chemical transported through a network of pipes and storage tanks, such as a fluoride used in a tracer study or free chlorine used in a disinfection decay study. Recently, the NHSRC released a new extension to EPANET called EPANET-MSX (Multi-Species eXtension) that allows for the consideration of multiple interacting species in the bulk flow and on the pipe walls. This capability has been incorporated into both a stand-alone executable program as well as a toolkit library of functions that programmers can use to build customized applications.

Decentring poverty, reworking government: social movements and states in the government of poverty.

The significance of social movements for pro-poor political and social change is widely acknowledged. Poverty reduction has assumed increasing significance within development debates, discourses and programmes - how do social movement leaders and activists respond? This paper explores this question through the mapping of social movement organisations in Peru and South Africa. We conclude that for movement activists 'poverty' is rarely a central concern. Instead, they represent their actions as challenging injustice, inequality and/or development models with which they disagree, and reject the simplifying and sectoral orientation of poverty reduction interventions. In today's engagement with the poverty-reducing state, their challenge is to secure resources and influence without becoming themselves subject to, or even the subjects of, the practices of government.

Summary Background Rheumatic heart disease (RHD) remains a major disease burden in low-resource settings globally. Patient registers have long been recognised to be an essential instrument in RHD control and elimination programmes, yet to date rely heavily on paper-based data collection and non-networked data-management systems, which limit their functionality. Objectives To assess the feasibility and potential benefits of producing an electronic RHD patient register. Methods We developed an eRegister based on the World Heart Federation’s framework for RHD patient registers using CommCare, an open-source, cloud-based software for health programmes that supports the development of customised data capture using mobile devices. Results The resulting eRegistry application allows for simultaneous data collection and entry by field workers using mobile devices, and by providers using computer terminals in clinics and hospitals. Data are extracted from CommCare and are securely uploaded into a cloud-based database that matches the criteria established by the WHF framework. The application can easily be tailored to local needs by modifying existing variables or adding new ones. Compared with traditional paper-based data-collection systems, the eRegister reduces the risk of data error, synchronises in real-time, improves clinical operations and supports management of field team operations. Conclusions The user-friendly eRegister is a low-cost, mobile, compatible platform for RHD treatment and prevention programmes based on materials sanctioned by the World Heart Federation. Readily adaptable to local needs, this paperless RHD patient register program presents many practical benefits. PMID:26444995

The challenges of good governance in the aquatic animal health sector.

PubMed

Kahn, S; Mylrea, G; Yaacov, K Bar

2012-08-01

Animal health is fundamental to efficient animal production and, therefore, to food security and human health. This holds true for both terrestrial and aquatic animals. Although partnership between producers and governmental services is vital for effective animal health programmes, many key activities are directly carried out by governmental services. Noting the need to improve the governance of such services in many developing countries, the World Organisation for Animal Health (OIE), using the OIE Tool for the Evaluation of Performance of Veterinary Services, conducts assessments of Veterinary Services and Aquatic Animal Health Services (AAHS) to help strengthen governance and support more effective delivery of animal health programmes. While good governance and the tools to improve governance in the aquatic animal sector are largely based on the same principles as those that apply in the terrestrial animal sector, there are some specific challenges in the aquatic sector that have a bearing on the governance of services in this area. For example, the aquaculture industry has experienced rapid growth and the use of novel species is increasing; there are important gaps in scientific knowledge on diseases of aquatic animals; there is a need for more information on sustainable production; the level of participation of the veterinary profession in aquatic animal health is low; and there is a lack of standardisation in the training of aquatic animal health professionals. Aquaculture development can be a means of alleviating poverty and hunger in developing countries. However, animal diseases, adverse environmental impacts and food safety risks threaten to limit this development. Strengthening AAHS governance and, in consequence, aquatic animal health programmes, is the best way to ensure a dynamic and sustainable aquaculture sector in future. This paper discusses the specific challenges to AAHS governance and some OIE initiatives to help Member Countries to address them.

Leaving the labour market: the impact of exit routes from employment to retirement on health and wellbeing in old age.

The study analyses whether and to what degree specific routes into retirement affect older people, i.e. the relationship between heterogeneous exit patterns and post-retirement health and wellbeing. We used longitudinal data from two points in time; data related to t 0 were collected in 1993, 1994, 1995 and 1996 and data related to t 1 were collected in 2002 and 2003 ( N  = 589). We focused on older people (55+ at t 1 ) who were employed at t 0 and retired at t 1 . We used confirmative factor analysis to identify identical measures of health and wellbeing at both t 0 and t 1 . Hence, we were able to control for pre-retirement health and wellbeing when evaluating the effects of different exit routes. These routes were defined as dependence on incomes from sickness benefit, disability pension, part-time pension, unemployment insurance and active labour market programmes. Our initial structural equation model showed a clear relation between exit routes and post-retirement wellbeing. People who prior to retirement were pushed into social benefit programmes related to health and unemployment were significantly worse off as retirees, especially those with health-related benefits. However, these relationships disappeared once pre-retirement wellbeing was added to the model. Our main conclusion is that post-retirement wellbeing first and foremost is a consequence of accumulation of advantages and disadvantages during the life course. Both labour market exit routes and post-retirement wellbeing can be seen as outcomes of this process. There are no independent effects of the retirement process. Judging from our findings, there is no reason to believe that involvement in social security programmes allowing early retirement on health grounds has any additional negative consequences for health and wellbeing.

Integrating microfinance and health strategies: examining the evidence to inform policy and practice.

Single solutions continue to be inadequate in confronting the prevalent problems of poverty, ill health and insufficient health system capacity worldwide. The poor need access to an integrated set of financial and health services to have income security and better health. Over 3500 microfinance institutions (MFIs) provide microcredit and financial services to more than 155 million households worldwide. Conservative estimates indicate that at least 34 million of these households are very poor by the definition in the Millennium Development Goals, representing around 170 million people, many in remote areas beyond the reach of health agencies, both private and governmental. A small but increasing number of MFIs offer health-related services, such as education, clinical care, community health workers, health-financing and linkages to public and private health providers. Multiple studies indicate the effectiveness of microfinance and its impact on poverty. A small but growing number of studies also attempt to show that MFIs are capable of contributing to health improvement by increasing knowledge that leads to behavioural changes, and by enhancing access to health services through addressing financial, geographic and other barriers. While these studies are of uneven quality, they indicate positive health benefits in diverse areas such as maternal and child health, malaria and other infectious disease, and domestic violence. While more rigorous research is needed to inform policy and guide programme implementation to integrate microfinance and health interventions that can reliably enhance the well-being of the poor, there is useful evidence to support the design and delivery of integrated programmes now. Worldwide, current public health programmes and health systems are proving to be inadequate to meet population needs. The microfinance sector offers an underutilized opportunity for delivery of health-related services to many hard-to-reach populations.

The fast increasing share of distributed generation from non-programmable renewable energy sources, such as the strong penetration of photovoltaic technology in the distribution networks, has generated several problems for the management and security of the whole power grid. In order to meet the challenge of a significant share of solar energy in the electricity mix, several actions aimed at increasing the grid flexibility and its hosting capacity, as well as at improving the generation programmability, need to be investigated. This paper focuses on the ongoing preliminary studies at the Ottana Solar Facility, a new experimental power plant located in Sardinia (Italy) currently under construction, which will offer the possibility to progress in the study of solar plants integration in the power grid. The facility integrates a concentrating solar power (CSP) plant, including a thermal energy storage system and an organic Rankine cycle (ORC) unit, with a concentrating photovoltaic (CPV) plant and an electrical energy storage system. The facility has the main goal to assess in real operating conditions the small scale concentrating solar power technology and to study the integration of the two technologies and the storage systems to produce programmable and controllable power profiles. A model for the CSP plant yield was developed to assess different operational strategies that significantly influence the plant yearly yield and its global economic effectiveness. In particular, precise assumptions for the ORC module start-up operation behavior, based on discussions with the manufacturers and technical datasheets, will be described. Finally, the results of the analysis of the: "solar driven", "weather forecasts" and "combined storage state of charge (SOC)/ weather forecasts" operational strategies will be presented.

The Farmers' Market Fresh Fund Incentive Program is a policy, systems and environmental intervention to improve access to fresh produce for participants on governmental assistance in the USA. The current study examined factors associated with ongoing participation in this matched monetary incentive programme. Relationship of baseline factors with number of Fresh Fund visits was assessed using Poisson regression. Mixed-effects modelling was used to explore changes in consumption of fruits and vegetables and diet quality. San Diego, California. Recipients of Supplemental Nutrition Assistance Program (SNAP), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and Supplemental Security Income (SSI) who attended participating farmers' markets from 2010 to 2012 (n 7298). Among those with participation for ≤6 months, factors associated with increased visits included reporting more daily servings of fruits and vegetables (F&V) at baseline, being Vietnamese or Asian/Pacific Islander, and eligibility because of SNAP/CalFresh or SSI (v. WIC). Among those who came for 6-12 months, being Asian/Pacific Islander, eligibility because of SNAP/CalFresh and enrolling in the autumn, winter or spring were associated with a greater number of Fresh Fund visits. Among those who came for >12 months, being male and eligibility because of SSI were associated with a greater number of visits. Overall, the odds of increasing number of servings of F&V consumed increased by 2 % per month, and the odds of improved perception of diet quality increased by 10 % per month. Sustaining and increasing Fresh Fund-type programme operations should be a top priority for future policy decisions concerning farmers' market use in low-income neighbourhoods.

The AMMA international project aims at improving our knowledge and understanding of the West African monsoon and its variability with an emphasis on daily-to-interannual timescales. AMMA is motivated by an interest in fundamental scientific issues and by the societal need for improved prediction of the WAM and its impacts on water resources, health and food security for West African nations. The West African monsoon (WAM) has a distinctive annual cycle in rainfall that remains a challenge to understand and predict. The location of peak rainfall, which resides in the Northern Hemisphere throughout the year, moves from the ocean to the land in boreal spring. Around the end of June there is a rapid shift in the location of peak rainfall between the coast and around 10°N where it remains until about the end of August. In September the peak rainfall returns equatorward at a relatively steady pace and is located over the ocean again by November. The fact that the peak rainfall migrates irregularly compared to the peak solar heating is due to the interactions that occur between the land, the atmosphere and the ocean. To gain a better understanding of this complex climate system, a large international research programme was launched in 2002, the biggest of its kind into environment and climate ever attempted in Africa. AMMA has involved a comprehensive field experiment bringing together ocean, land and atmospheric measurements, on timescales ranging from hourly and daily variability up to the changes in seasonal activity over a number of years. This presentation will focus on the description of the field programme and its accomplishments, and address some key questions that have been recently identified to form the core of AMMA-Phase 2.

2015-01-01

The purpose of this paper is to present basic elements of the research directed at identifying and determining the personality traits of professional drivers that affect safe, secure and enjoyable ride on public roads. A quantitative method has been used here, whereas data were acquired from a questionnaire based on a sample of 59 professional drivers. Determining personality traits of professional drivers that are in correlation with a safe and pleasant ride on the roads has been enabled by applying the five-factor model of personality ('Big Five') and the Personality Inventory NEO-PI. From these results it was concluded that safe operation of the vehicle in traffic involves the successful 'conduct' of oneself, which recognises the importance of certain personality traits of professional drivers for traffic safety and the need for appropriate professional selection in the case of employment of professional drivers. Research results implicate development of educational programmes aimed at achieving harmony of psychological, physical and sensory health, that is, programmes for permanent informing, educating and training professional drivers for defensive driving. The research opens the way for new research tasks that should help in creating a specific structure of curricula that can be used in a variety of transportation companies and enterprises to improve general and public safety.

HALO: a reconfigurable image enhancement and multisensor fusion system

Wu, F.; Hickman, D. L.; Parker, Steve J.

2014-06-01

Contemporary high definition (HD) cameras and affordable infrared (IR) imagers are set to dramatically improve the effectiveness of security, surveillance and military vision systems. However, the quality of imagery is often compromised by camera shake, or poor scene visibility due to inadequate illumination or bad atmospheric conditions. A versatile vision processing system called HALO™ is presented that can address these issues, by providing flexible image processing functionality on a low size, weight and power (SWaP) platform. Example processing functions include video distortion correction, stabilisation, multi-sensor fusion and image contrast enhancement (ICE). The system is based around an all-programmable system-on-a-chip (SoC), which combines the computational power of a field-programmable gate array (FPGA) with the flexibility of a CPU. The FPGA accelerates computationally intensive real-time processes, whereas the CPU provides management and decision making functions that can automatically reconfigure the platform based on user input and scene content. These capabilities enable a HALO™ equipped reconnaissance or surveillance system to operate in poor visibility, providing potentially critical operational advantages in visually complex and challenging usage scenarios. The choice of an FPGA based SoC is discussed, and the HALO™ architecture and its implementation are described. The capabilities of image distortion correction, stabilisation, fusion and ICE are illustrated using laboratory and trials data.

On Polymorphic Circuits and Their Design Using Evolutionary Algorithms

Stoica, Adrian; Zebulum, Ricardo; Keymeulen, Didier; Lohn, Jason; Clancy, Daniel (Technical Monitor)

2002-01-01

This paper introduces the concept of polymorphic electronics (polytronics) - referring to electronics with superimposed built-in functionality. A function change does not require switches/reconfiguration as in traditional approaches. Instead the change comes from modifications in the characteristics of devices involved in the circuit, in response to controls such as temperature, power supply voltage (VDD), control signals, light, etc. The paper illustrates polytronic circuits in which the control is done by temperature, morphing signals, and VDD respectively. Polytronic circuits are obtained by evolutionary design/evolvable hardware techniques. These techniques are ideal for the polytronics design, a new area that lacks design guidelines, know-how,- yet the requirements/objectives are easy to specify and test. The circuits are evolved/synthesized in two different modes. The first mode explores an unstructured space, in which transistors can be interconnected freely in any arrangement (in simulations only). The second mode uses a Field Programmable Transistor Array (FPTA) model, and the circuit topology is sought as a mapping onto a programmable architecture (these experiments are performed both in simulations and on FPTA chips). The experiments demonstrated the synthesis. of polytronic circuits by evolution. The capacity of storing/hiding "extra" functions provides for watermark/invisible functionality, thus polytronics may find uses in intelligence/security applications.

There is extensive research on African girls sexual experiences, but much less is known about boys thoughts and actions. There is a need to understand the male perspective in order to develop sexuality education programmes that address the high rates of teenage pregnancy and sexually transmitted infections in sub-Saharan Africa. For this qualitative, phenomenological study we spoke to 20 boys from Bolgatanga, Ghana and explored their sexual decision making, using semi-structured interviews designed to highlight psychosocial and environmental factors. Content analysis was used to construct categories and later the themes. Boys often had negative perceptions about sexual relationships. They believed that girls could not be trusted and mostly embarked on sexual relationships for material gain. The boys reported engaging in multiple sexual partnerships to secure their masculine status; however, they expected girls to be 'faithful'. We found that accurate knowledge of safe sex was lacking, boys were under peer pressure to conform to beliefs about masculinity and communication about sex mainly took place within peer groups. There is a need to emphasise condom use in established relationships. There should also be more discussion of issues surrounding fidelity and gender equality, as part of sexuality programmes aimed at boys in Ghana and in similar cultures.

Evaluation can enhance implementation of such an approach and demonstrate the extent of effectiveness. To be able to support professionals in the evaluation of ICIAs we studied barriers to and facilitators of ICIA evaluation. In this study ten professionals of two Dutch municipalities involved in the evaluation of an ICIA participated. We conducted semi-structured interviews (n = 12), observed programme meetings (n = 4) and carried out document analysis. Data were analyzed using a thematic content approach. We learned that evaluation is hampered when it is perceived as unfeasible due to limited time and budget, a lack of evaluation knowledge or a negative evaluation attitude. Other barriers are a poor understanding of the evaluation process and its added value to optimizing the programme. Sufficient communication between involved professionals on evaluation can facilitate evaluation, as does support for evaluation of ICIAs together with stakeholders at a strategic and tactical level. To stimulate the evaluation of ICIAs, we recommend supporting professionals in securing evaluation resources, providing tailored training and tools to enhance evaluation competences and stimulating strategic communication on evaluation.

In an academic programme, completion of a postgraduate degree project could be a significant means of promoting student learning in evidence- and experience-based practice. In specialist nursing education, which through the European Bologna process would be raised to the master's level, there is no tradition of including a postgraduate degree project. The aim was to develop a didactic model for specialist nursing students' postgraduate degree projects within the second cycle of higher education (master's level) and with a specific focus on nurturing shared involvement between universities and healthcare settings. This study embodies a participatory action research and theory-generating design founded on empirically practical try-outs. The 3-year project included five Swedish universities and related healthcare settings. A series of activities was performed and a number of data sources secured. Constant comparative analysis was applied. A didactic model is proposed for postgraduate degree projects in specialist nursing education aimed at nurturing shared involvement between universities and healthcare settings. The focus of the model is student learning in order to prepare the students for participation as specialist nurses in clinical knowledge development. The model is developed for the specialist nursing education, but it is general and could be applicable to various education programmes.

Nuclear Power: Is It a New Clear Choice for Malaysia

Energy is essential for socio-economic development. Any nation's standard of living is closely related to its access to energy. To put into perspective, the per capita electricity consumptions in developed countries of the Organisation for Economic Cooperation and Development (OECD) is currently estimated at 8600 kilowatts-hour per year as compared to the consumption rates in Malaysia and some African countries of 3300 and 50 kilowatts-hour per year, respectively. Energy is therefore an important pre-requisite for achieving the Malaysian vision of becoming a developed nation by the year 2020, in that it is needed not only for industrialization programme but also in maintaining quality of life. In Malaysia, the main concern currently is still on the supply in term of adequacy, reliability and quality; and moving slowly but steadily towards security, sustainability, environmentally friendly and contribution to climate change. With this new dimension, nuclear power emerged as a good match to a possible alternative in the comprehensive national energy policy. Many studies presented the positive aspects of nuclear power while others indicated the bad sides and potential risks. This paper will highlight some of those pros and cons as well as the potential risks beside a discussion on relevant requirements for a nuclear power programme in particular those of interest to the professionals in the physical sciences.

2015-12-01

Our recent research on water security (Sadoff et al., 2015, Dadson et al., 2015) has revealed the dynamic relationship between water security and human well-being. A version of this dynamic is materialising in the coastal polder areas of Khulna, Bangladesh. Repeated coastal floods increase salinity, wipe out agricultural yields for several years and increase out-migration. As a tool to help inform and target future cycles of investment in improvements to the coastal embankments, in this paper we propose a dynamical model of biophysical processes and human well-being, which downscales our previous research to the Khulna region. State variables in the model include agricultural production, population, life expectancy and child mortality. Possible infrastructure interventions include embankment improvements, groundwater wells and drainage infrastructure. Hazard factors include flooding, salinization and drinking water pollution. Our system model can be used to inform adaptation decision making by testing the dynamical response of the system to a range of possible policy interventions, under uncertain future conditions. The analysis is intended to target investment and enable adaptive resource reallocation based on learning about the system response to interventions over the seven years of our research programme. The methodology and paper will demonstrate the complex interplay of factors that determine system vulnerability to climate change. The role of climate change uncertainties (in terms of mean sea level rise and storm surge frequency) will be evaluated alongside multiple other uncertain factors that determine system response. Adaptive management in a 'learning system' will be promoted as a mechanism for coping with climate uncertainties. References:Dadson, S., Hall, J.W., Garrick, D., Sadoff, C. and Grey, D.

Health services are increasingly required to measure outcomes after treatment, which can be reported to the funding body and may be scrutinised by the public. Extensive high-quality measurements are time consuming. Routinely collected clinical data might, if anonymised, provide good enough evidence of useful change consequent on service received. Do the Health of the Nation Scale and the 20-item Historical, Clinical, Risk structured professional judgement tool scores provide evidence of clinical and risk change among low security hospital patients at 6 and 12 months after admission? One hundred and eight men were either resident on the unit on 1 January 2011 or new admissions to the census date of 31 May 2013. Their routinely collected data were added to an outcome register following each patient's Care Programme Approach clinical review meeting and analysed using repeated measures t-tests with Bonferroni corrections. Most of the men, mean age 34.3 years, were single (93%), White British (71%) and with a primary diagnosis of schizophrenia (62%). There were significant reductions in the 11-item Health of the Nation Scale (excluding the community living condition scale) scores between baseline and 6 months and between 6 and 12 months, but no change on its additional 7-item secure subscale. Individual effect sizes indicated that 39% of the men had better social function, although 18% had deteriorated at 6 months. There was little overall change in the 20-item Historical, Clinical, Risk; individual effect sizes indicated that 11 men (15%) were rated as being at lower risk level and 10 (14%) at higher after 6 months in the study. Standard clinical measures are promising as indicators of change in low security hospital patients. Risk ratings may be conservative, but at this stage of a secure hospital admission, higher scores may be as likely to indicate progress in identifying and quantifying risks as apparent increase in risk.

As low income countries experience economic transition, characterized by rapid economic growth and increased government spending potential in health, they have increased fiscal space to support and sustain more of their own health programmes, decreasing need for donor development assistance. Phase out of external funds should be systematic and efforts towards this end should concentrate on government commitments towards country ownership and self-sustainability. The 2006 US Agency for International Development (USAID) family planning (FP) graduation strategy is one such example of a systematic phase-out approach. Triggers for graduation were based on pre-determined criteria and programme indicators. In 2011 the GAVI Alliance (formerly the Global Alliance for Vaccines and Immunizations) which primarily supports financing of new vaccines, established a graduation policy process. Countries whose gross national income per capita exceeds $1570 incrementally increase their co-financing of new vaccines over a 5-year period until they are no longer eligible to apply for new GAVI funding, although previously awarded support will continue. This article compares and contrasts the USAID and GAVI processes to apply lessons learned from the USAID FP graduation experience to the GAVI process. The findings of the review are 3-fold: (1) FP graduation plans served an important purpose by focusing on strategic needs across six graduation plan foci, facilitating graduation with pre-determined financial and technical benchmarks, (2) USAID sought to assure contraceptive security prior to graduation, phasing out of contraceptive donations first before phasing out from technical assistance in other programme areas and (3) USAID sought to sustain political support to assure financing of products and programmes continue after graduation. Improving sustainability more broadly beyond vaccine financing provides a more comprehensive approach to graduation. The USAID FP experience provides a window into understanding one approach to graduation from donor assistance. The process itself-involving transparent country-level partners well in advance of graduation-appears a valuable lesson towards success. Published by Oxford University Press 2014.

2010-12-01

In 2009 European Space Agency (ESA) started a new programme called Space Situational Awareness (SSA) Preparatory Programme. The objective of the programme is to support the European independent utilisation of and access to space research or services. This will be performed through providing timely and quality data, information, services and knowledge regarding the environment, the threats and the sustainable exploitation of the outer space surrounding the planet Earth. SSA serves the implementation of the strategic missions of the European Space Policy based on the peaceful uses of the outer space by all states, by supporting the autonomous capacity to securely and safely operate the critical European space infrastructures. The SSA Preparatory Program will establish the initial elements that will eventually lead into the full deployment of the European SSA services. The SWE Segment of the SSA will provide user services related to the monitoring of the Sun, the solar wind, the radiation belts, the magnetosphere and the ionosphere. These services will include near real time information and forecasts about the characteristics of the space environment and predictions of space weather impacts on sensitive spaceborne and ground based infrastructure. The SSA SWE system will also include establishment of a permanent database for analysis, model development and scientific research. These services are will support a wide variety of user domains including spacecraft designers, spacecraft operators, human space flights, users and operators of transionospheric radio links, and space weather research community. The precursor SWE services to be established starting in 2010 will include a selected subset of these services based on pre-existing space weather applications and services in Europe. This paper will present the key characteristics of the SSA SWE system that is currently being designed. The presentation will focus on the system characteristics that support space weather forecasting and the related services. The presentation will show results from the analysis of the existing European assets and the identified development needs in the mid and long term future to ensure forecasting capability for the services requested the by SSA SWE users. The analysis covers the future SSA SWE space segment and the service development needs for the ground segment.

Mobile phone text messaging has been shown to improve adherence to antiretroviral therapy and to improve communication between patients and health care workers. It is unclear which strategies are most appropriate for scaling up text messaging programmes. We sought to investigate acceptability and readiness for ownership (community members designing, sending and receiving text messages) of a text message programme among a community of clients living with human immunodeficiency virus (HIV) in Yaoundé, Cameroon and to develop a framework for implementation. We used the mixed-methods sequential exploratory design. In the qualitative strand we conducted 7 focus group discussions (57 participants) to elicit themes related to acceptability and readiness. In the quantitative strand we explored the generalizability of these themes in a survey of 420 clients. Qualitative and quantitative data were merged to generate meta-inferences. Both qualitative and quantitative strands showed high levels of acceptability and readiness despite low rates of participation in other community-led projects. In the qualitative strand, compared to the quantitative strand, more potential service users were willing to pay for a text messaging service, preferred participation of health personnel in managing the project and preferred that the project be based in the hospital rather than in the community. Some of the limitations identified to implementing a community-owned project were lack of management skills in the community, financial, technical and literacy challenges. Participants who were willing to pay were more likely to find the project acceptable and expressed positive feelings about community readiness to own a text messaging project. Community ownership of a text messaging programme is acceptable to the community of clients at the Yaoundé Central Hospital. Our framework for implementation includes components for community members who take on roles as services users (demonstrating clear benefits, allowing a trial period and ensuring high levels of confidentiality) or service providers (training in project management and securing sustainable funding). Such a project can be evaluated using participation rate, clinical outcomes, satisfaction with the service, cost and feedback from users.

The Kilimanjaro Diabetic Programme was initiated in response to the needs of people living with diabetes (PWLD) to identify barriers to uptake of screening for diabetic retinopathy, to improve management of diabetes, and establish an affordable, sustainable eye screening and treatment programme for diabetic retinopathy. Intervention Mapping was used as the framework for the needs assessment. A mixed methods approach was used. Five psychometric measures, Diabetes Knowledge Questionnaire, Diabetes Health Beliefs, Self-Efficacy scale, Problem Areas in Diabetes scale, and Hopkins Scale Checklist-25 and a structured interview relating to self-efficacy, addressing disclosure of living with diabetes and life-style changes were used to triangulate the quantitative findings. These were administered to 26 PWLD presenting to rural district hospitals. The interviewees demonstrated low levels of perceived stigma regarding disclosure of living with diabetes and high levels of self-efficacy in raising community awareness of diabetes, seeking on going treatment from Western medicine over traditional healers and in seeking care on sick days. Self-efficacy was high for adjusting diet, although comprehensive dietary knowledge was poor. Negative emotions expressed at diagnosis, changes in life style and altered quality of life were reflected in high levels of anxiety and depression. Low levels of stigma surrounding living with diabetes were linked to a desire to raise community awareness of diabetes, help others live with diabetes and to secure social support to access hospital services. Confusion over what constituted a healthy diet showed the importance of comprehensive, accessible diabetes education, essential to ensuring good glycaemic control, and preventing diabetic complications, including diabetic retinopathy. Low levels of self-efficacy along with high levels of anxiety and depression may have a negative impact on the uptake of screening for Diabetic Retinopathy. The findings of this needs assessment led to the planning and delivery of a comprehensive health intervention programme for PLWD in Kilimanjaro Region. The programme has provided them with support, resources, education, and screening for diabetic retinopathy at the regional hospital and at district level with mobile digital retinal cameras, an electronic diabetic database and computerised follow up to ensure continuity of care.

SU-E-T-64: A Programmable Moving Insert for the ArcCHECK Phantom for Dose Verification of Respiratory-Gated VMAT

Gaede, S; Jordan, K; Western University, London, ON

Purpose: To present a customized programmable moving insert for the ArcCHECK™ phantom that can, in a single delivery, check both entrance dosimetry, while simultaneously verifying the delivery of respiratory-gated VMAT. Methods: The cylindrical motion phantom uses a computer-controlled stepping motor to move an insert inside a stationery sleeve. Insert motion is programmable and can include rotational motion in addition to linear motion along the axis of the cylinder. The sleeve fits securely in the bore of the ArcCHECK™. Interchangeable inserts, including an A1SL chamber, optically-stimulated luminescence dosimeters, radiochromic film, or 3D gels, allow this combination to be used for commissioning,more » routine quality assurance, and patient-specific dosimetric verification of respiratory-gated VMAT. Before clinical implementation, the effect of a moving insert on the ArcCHECK™ measurements was considered. First, the measured dose to the ArcCHECK™ containing multiple inserts in the static position was compared to the calculated dose during multiple VMAT treatment deliveries. Then, dose was measured under both sinusoidal and real-patient motion conditions to determine any effect of the moving inserts on the ArcCHECK™ measurements. Finally, dose was measured during gated VMAT delivery to the same inserts under the same motion conditions to examine any effect of various beam “on-and-off” and dose rate ramp “up-and-down”. Multiple comparisons between measured and calculated dose to different inserts were also considered. Results: The pass rate for the static delivery exceeded 98% for all measurements (3%/3mm), suggesting a valid setup for entrance dosimetry. The pass rate was not altered for any measurement delivered under motion conditions. A similar Result was observed under gated VMAT conditions, including agreement of measured and calculated dose to the various inserts. Conclusion: Incorporating a programmable moving insert within the ArcCHECK™ phantom provides an efficient verification of respiratory-gated VMAT delivery that is useful during commissioning, routine quality assurance, and patient-specific dose verification. Prototype phantom development and testing was performed in collaboration with Modus Medical Devices Inc. (London, ON). No financial support was granted.« less

Utilizing Internet Technologies in Observatory Control Systems

The 'Internet boom' of the past few years has spurred the development of a number of technologies to provide services such as secure communications, reliable messaging, information publishing and application distribution for commercial applications. Over the same period, a new generation of computer languages have also developed to provide object oriented design and development, improved reliability, and cross platform compatibility. Whilst the business models of the 'dot.com' era proved to be largely unviable, the technologies that they were based upon have survived and have matured to the point were they can now be utilized to build secure, robust and complete observatory control control systems. This paper will describe how Electro Optic Systems has utilized these technologies in the development of its third generation Robotic Observatory Control System (ROCS). ROCS provides an extremely flexible configuration capability within a control system structure to provide truly autonomous robotic observatory operation including observation scheduling. ROCS was built using Internet technologies such as Java, Java Messaging Service (JMS), Lightweight Directory Access Protocol (LDAP), Secure Sockets Layer (SSL), eXtendible Markup Language (XML), Hypertext Transport Protocol (HTTP) and Java WebStart. ROCS was designed to be capable of controlling all aspects of an observatory and be able to be reconfigured to handle changing equipment configurations or user requirements without the need for an expert computer programmer. ROCS consists of many small components, each designed to perform a specific task, with the configuration of the system specified using a simple meta language. The use of small components facilitates testing and makes it possible to prove that the system is correct.

Background Functional national laboratory networks and systems are indispensable to the achievement of global health security targets according to the International Health Regulations. The lack of indicators to measure the functionality of national laboratory network has limited the efficiency of past and current interventions to enhance laboratory capacity in resource-limited-settings. Scorecard for laboratory networks We have developed a matrix for the assessment of national laboratory network functionality and progress thereof, with support from the African Society of Laboratory Medicine and the Association of Public Health Laboratories. The laboratory network (LABNET) scorecard was designed to: (1) Measure the status of nine overarching core capabilities of laboratory network required to achieve global health security targets, as recommended by the main normative standards; (2) Complement the World Health Organization joint external evaluation tool for the assessment of health system preparedness to International Health Regulations (2005) by providing detailed information on laboratory systems; and (3) Serve as a clear roadmap to guide the stepwise implementation of laboratory capability to prevent, detect and act upon infectious threats. Conclusions The application of the LABNET scorecard under the coordination of the African Society of Laboratory Medicine and the Association of Public Health Laboratories could contribute to the design, monitoring and evaluation of upcoming Global Health Security Agenda-supported laboratory capacity building programmes in sub Saharan-Africa and other resource-limited settings, and inform the development of national laboratory policies and strategic plans. Endorsement by the World Health Organization Regional Office for Africa is foreseen. PMID:28879141

Impact of climate change on crop yield and role of model for achieving food security.

PubMed

Kumar, Manoj

2016-08-01

In recent times, several studies around the globe indicate that climatic changes are likely to impact the food production and poses serious challenge to food security. In the face of climate change, agricultural systems need to adapt measures for not only increasing food supply catering to the growing population worldwide with changing dietary patterns but also to negate the negative environmental impacts on the earth. Crop simulation models are the primary tools available to assess the potential consequences of climate change on crop production and informative adaptive strategies in agriculture risk management. In consideration with the important issue, this is an attempt to provide a review on the relationship between climate change impacts and crop production. It also emphasizes the role of crop simulation models in achieving food security. Significant progress has been made in understanding the potential consequences of environment-related temperature and precipitation effect on agricultural production during the last half century. Increased CO2 fertilization has enhanced the potential impacts of climate change, but its feasibility is still in doubt and debates among researchers. To assess the potential consequences of climate change on agriculture, different crop simulation models have been developed, to provide informative strategies to avoid risks and understand the physical and biological processes. Furthermore, they can help in crop improvement programmes by identifying appropriate future crop management practises and recognizing the traits having the greatest impact on yield. Nonetheless, climate change assessment through model is subjected to a range of uncertainties. The prediction uncertainty can be reduced by using multimodel, incorporating crop modelling with plant physiology, biochemistry and gene-based modelling. For devloping new model, there is a need to generate and compile high-quality field data for model testing. Therefore, assessment of agricultural productivity to sustain food security for generations is essential to maintain a collective knowledge and resources for preventing negative impact as well as managing crop practises.

"Health regains but livelihoods lag": findings from a study with people on ART in Zambia and Kenya.

Although ART is increasingly accessible and eases some stresses, it creates other challenges including the importance of food security to enhance ART-effectiveness. This paper explores the role livelihood strategies play in achieving food security and maintaining nutritional status among ART patients in Kenya and Zambia. Ongoing quantitative studies exploring adherence to ART in Mombasa, Kenya (n=118) and in Lusaka, Zambia (n=375) were used to identify the relationship between BMI and adherence; an additional set of in-depth interviews with people on ART (n=32) and members of their livelihood networks (n=64) were undertaken. Existing frameworks and scales for measuring food security and a positive deviance approach was used to analyse data. Findings show the majority of people on ART in Zambia are food insecure; similarly most respondents in both countries report missing meals. Snacking is important for dietary intake, especially in Kenya. Most food is purchased in both countries. Having assets is key for achieving livelihood security in both Kenya and Zambia. Food supplementation is critical to survival and for developing social capital since most is shared amongst family members and others. Whilst family and friends are key to an individual's livelihood network, often more significant for daily survival is proximity to people and the ability to act immediately, characteristics most often found amongst neighbours and tenants. In both countries findings show that with ART health has rebounded but livelihoods lag. Similarly, in both countries respondents with high adherence and high BMI are more self-reliant, have multiple income sources and assets; those with low adherence and low BMI have more tenuous livelihoods and were less likely to have farms/gardens. Food supplementation is, therefore, not a long-term solution. Building on existing livelihood strategies represents an alternative for programme managers and policy-makers as do other strategies including supporting skills and asset accumulation.

The micrometeorological base of CNR-ISAC in Lecce, South-East of Italy, is active since 2002, in collecting experimental data about surface-atmosphere transfer of momentum heat and water vapour. It operates in a periurban site inside the Salento University campus and has been improved along the past years in terms of active sensors to give a quite complete description of the soil-atmosphere vertical transfer. It is composed by a 16 m mast with fast response (eddy correlation) instrumentation and an ancillary automatic meteorological station collecting also soil data at 2 levels depth. Fast response data are pre-processed in half-hour averaged statistics. All collected data are available in a web database (www.basesperimentale.le.isac.cnr.it) where they can be visualized or downloaded. A real time automated connection between the base and the data base is also in progress. At present the Lecce data base is also a pilot reference structure for the Climate Change Section of the CNR-DTA GIIDA project (National Research Council - Earth and Environment Department, Interdisciplinary and Interoperational Management of Environmental Data), aimed to build a spatial data infrastructure between different CNR-DTA structures collecting environmental data. This will allow easier search and availability for a great deal of environmental information in terms of data associated to international quality standards and metadata systems (GEOSS, GMES, INSPIRE).

Hacking medical devices a review - biomed 2013.

Frenger, Paul

2013-01-01

Programmable, implantable and external biomedical devices (such as pacemakers, defibrillators, insulin pumps, pain management pumps, vagus nerve stimulators and others) may be vulnerable to unauthorized access, commonly referred to as “hacking”. This intrusion may lead to compromise of confidential patient data or loss of control of the device itself, which may be deadly. Risks to health from unauthorized access is in addition to hazards from faulty (“buggy”) software or circuitry. Historically, this aspect of medical device design has been underemphasized by both manufacturers and regulatory bodies until recently. However, an insulin pump was employed as a murder weapon in 2001 and successful hacking of an implantable defibrillator was demonstrated in 2008. To remedy these problems, professional groups have announced a variety of design standards and the governmental agencies of several countries have enacted device regulations. In turn, manufacturers have developed new software products and hardware circuits to assist biomedical engineering firms to improve their commercial offerings. In this paper the author discusses these issues, reviewing known problems and zero-day threats, with potential solutions. He outlines his approach to secure software and hardware challenges using the Forth language. A plausible scenario is described in which hacking of an implantable defibrillator by terrorists results in a severe national security threat to the United States.

TeleFood: a worldwide appeal.

PubMed

1997-12-01

In 1997, the UN Food and Agriculture Organization (FAO) broadcast its first global television program on the theme of "Food for All" to an audience of approximately 450 million viewers. The objective of "TeleFood" was to raise awareness of the scale of the problem and to encourage solidarity in the fight against hunger. TeleFood raised funds to support the FAO's Special Programme for Food Security (SPFS) and similar grassroots projects that target rural people in developing countries. The SPFS project, now operational in 19 countries and being formulated in 32 more, emphasizes national ownership, farmer participation, environmental awareness, and recognition of the role of women in food production and marketing. The 3-year SPFS pilot phase involves 1) small-scale water harvesting, irrigation, and drainage; 2) sustainable intensification of crop production; 3) diversification of production; and 4) removal of policies that impede food security. Results to date include 1) greatly increased maize and potato yields in Bolivia and more modest increases in Nepal; 2) doubled yields of maize and rice in Tanzania; and 3) expansion of the area under low-cost irrigation in Zambia. South-South cooperation is allowing some developing countries to benefit from experience gained in other developing countries. The pilot activities are being funded with an increasing number of "soft" loans from governments and financial institutions.

Engineering Trade-off Considerations Regarding Design-for-Security, Design-for-Verification, and Design-for-Test

The United States government has identified that application specific integrated circuit (ASIC) and field programmable gate array (FPGA) hardware are at risk from a variety of adversary attacks. This finding affects system security and trust. Consequently, processes are being developed for system mitigation and countermeasure application. The scope of this tutorial pertains to potential vulnerabilities and countermeasures within the ASIC/FPGA design cycle. The presentation demonstrates how design practices can affect the risk for the adversary to: change circuitry, steal intellectual property, and listen to data operations. An important portion of the design cycle is assuring the design is working as specified or as expected. This is accomplished by exhaustive testing of the target design. Alternatively, it has been shown that well established schemes for test coverage enhancement (design-for-verification (DFV) and design-for-test (DFT)) can create conduits for adversary accessibility. As a result, it is essential to perform a trade between robust test coverage versus reliable design implementation. The goal of this tutorial is to explain the evolution of design practices; review adversary accessibility points due to DFV and DFT circuitry insertion (back door circuitry); and to describe common engineering trade-off considerations for test versus adversary threats.

Compulsory Community Service (CCS) was introduced into the health service by the government to address the shortage and maldistribution of health professionals within the public sector. The aim of this study was to assess the perceptions of oral hygiene (OH) students, registered in 2004 at the five dental universities regarding the introduction of a 1-year-long CCS. To determine: (a) the students' socio-demographic profile and (b) their attitudes towards CCS. A self-administered questionnaire was hand delivered to all OH students who were registered during 2004 at the respective dental universities. The study yielded a response rate of 70% (109) with the average age of participants being 21.4 years. Most students were female (94%) and more than half were White (52%). More than half (53%) did not want to perform CCS even though 75% acknowledged its' importance. The most common concern for not supporting CCS was security (89%). Ninety per cent (90%) indicated that their preferred tasks would be to engage in clinical work and oral health promotion. Although the majority of participants supported the principles of CCS, a significant number were against the introduction citing security as their main concern. Most of the students preferred to perform clinical work and preventive programmes during their CCS.

This paper reports on a complex environmental approach to addressing 'wicked' health promotion problems devised to inform policy for enhancing food security and physical activity among Māori, Pacific and low-income people in New Zealand. This multi-phase research utilized literature reviews, focus groups, stakeholder workshops and key informant interviews. Participants included members of affected communities, policy-makers and academics. Results suggest that food security and physical activity 'emerge' from complex systems. Key areas for intervention include availability of money within households; the cost of food; improvements in urban design and culturally specific physical activity programmes. Seventeen prioritized intervention areas were explored in-depth and recommendations for action identified. These include healthy food subsidies, increasing the statutory minimum wage rate and enhancing open space and connectivity in communities. This approach has moved away from seeking individual solutions to complex social problems. In doing so, it has enabled the mapping of the relevant systems and the identification of a range of interventions while taking account of the views of affected communities and the concerns of policy-makers. The complex environmental approach used in this research provides a method to identify how to intervene in complex systems that may be relevant to other 'wicked' health promotion problems.

Primary care is at the centre of the National Health Service (NHS) in Scotland; however, its R & D capacity is insufficiently developed. R&D is a potentially powerful way of improving the health and well-being of the population, and of securing high quality care for those who need it. In order to achieve this, any Scottish strategy for primary care R&D should aim to develop both a knowledge-based service and a research culture in primary care. In this way, decisions will be made based upon best available evidence, whatever the context. Building on existing practice and resources within primary care research, this strategy for achieving a thriving research culture in Scottish primary care has three key components: A Scottish School of Primary Care which will stimulate and co-ordinate a cohesive programme of research and training. A comprehensive system of funding for training and career development which will ensure access to a range of research training which will ensure that Scotland secures effective leadership for its primary care R&D. Designated research and development practices (DRDPs) which will build on the work of existing research practices, in the context of Local Health Care Co-operatives (LHCCs) and Primary Care Trusts (PCTs), to create a co-operative environment in which a range of primary care professionals can work together to improve their personal and teams' research skills, and to support research development in their areas. A modest investment will create substantial increases in both the quality and quantity of research being undertaken in primary care. This investment should be targeted at both existing primary care professionals working in service settings in primary care, LHCCs and PCTs, and at centres of excellence (including University departments). A dual approach will foster collaboration and will allow existing centres of excellence both to undertake more primary care research and to support the development of service based primary care professionals in their research. Resources should be distributed equitably, taking into account demography, geography and the health needs of patients in Scotland. The strategy and its components must be seen as a whole. The Scottish School of Primary Care will stimulate and co-ordinate both research and training programmes. DRDPs will become research active and will participate in School-led training and research, and will contribute to research programmes. Comprehensive funding for training and career development will ensure that staff have the skills to participate in both DRDPs and in the School's activities. Thus, inadequate commitment to any one component of the strategy will mean that other components will be less successful. Commitment to all three components will maximise the chances of success.

Impact and sustainability of low-head drip irrigation kits, in the semi-arid Gwanda and Beitbridge Districts, Mzingwane Catchment, Limpopo Basin, Zimbabwe

Moyo, Richard; Love, David; Mul, Marloes; Mupangwa, Walter; Twomlow, Steve

Resource-poor smallholder farmers in the semi-arid Gwanda and Beitbridge districts face food insecurity on an annual basis due to a combination of poor and erratic rainfall (average 500 mm/a and 345 mm/a, respectively, for the period 1970-2003) and technologies inappropriate to their resource status. This impacts on both household livelihoods and food security. In an attempt to improve food security in the catchment a number of drip kit distribution programmes have been initiated since 2003 as part of an on-going global initiative aimed at 2 million poor households per year. A number of recent studies have assessed the technical performance of the drip kits in-lab and in-field. In early 2005 a study was undertaken to assess the impacts and sustainability of the drip kit programme. Representatives of the NGOs, local government, traditional leadership and agricultural extension officers were interviewed. Focus group discussions with beneficiaries and other villagers were held at village level. A survey of 114 households was then conducted in two districts, using a questionnaire developed from the output of the interviews and focus group discussions. The results from the study showed that the NGOs did not specifically target the distribution of the drip kits to poor members of the community (defined for the purpose of the study as those not owning cattle). Poor households made up 54% of the beneficiaries. This poor targeting of vulnerable households could have been a result of conditions set by some implementing NGOs that beneficiaries must have an assured water source. On the other hand, only 2% of the beneficiaries had used the kit to produce the expected 5 harvests over the 2 years, owing to problems related to water shortage, access to water and also pests and diseases. About 51% of the respondents had produced at least 3 harvests and 86% produced at least 2 harvests. Due to water shortages during the dry season 61% of production with the drip kit occurred during the wet season. This suggests that most households use the drip kits as supplementary irrigation. Conflicts between beneficiaries and water point committees or other water users developed in some areas especially during the dry season. The main finding from this study was that low cost drip kit programs can only be a sustainable intervention if implemented as an integral part of a long-term development program, not short-term relief programs and the programme should involve a broad range of stakeholders. A first step in any such program, especially in water scarce areas such as Gwanda and Beitbridge, is a detailed analysis of the existing water resources to assess availability and potential conflicts, prior to distribution of drip kits.

Background Gait restoration is an integral part of rehabilitation of brain lesioned patients. Modern concepts favour a task-specific repetitive approach, i.e. who wants to regain walking has to walk, while tone-inhibiting and gait preparatory manoeuvres had dominated therapy before. Following the first mobilization out of the bed, the wheelchair-bound patient should have the possibility to practise complex gait cycles as soon as possible. Steps in this direction were treadmill training with partial body weight support and most recently gait machines enabling the repetitive training of even surface gait and even of stair climbing. Results With treadmill training harness-secured and partially relieved wheelchair-mobilised patients could practise up to 1000 steps per session for the first time. Controlled trials in stroke and SCI patients, however, failed to show a superior result when compared to walking exercise on the floor. Most likely explanation was the effort for the therapists, e.g. manually setting the paretic limbs during the swing phase resulting in a too little gait intensity. The next steps were gait machines, either consisting of a powered exoskeleton and a treadmill (Lokomat, AutoAmbulator) or an electromechanical solution with the harness secured patient placed on movable foot plates (Gait Trainer GT I). For the latter, a large multi-centre trial with 155 non-ambulatory stroke patients (DEGAS) revealed a superior gait ability and competence in basic activities of living in the experimental group. The HapticWalker continued the end effector concept of movable foot plates, now fully programmable and equipped with 6 DOF force sensors. This device for the first time enables training of arbitrary walking situations, hence not only the simulation of floor walking but also for example of stair climbing and perturbations. Conclusion Locomotor therapy is a fascinating new tool in rehabilitation, which is in line with modern principles of motor relearning promoting a task-specific repetitive approach. Sophisticated technical developments and positive randomized controlled trials form the basis of a growing acceptance worldwide to the benefits or our patients. PMID:17291335

What have health care reforms achieved in Turkey? An appraisal of the "Health Transformation Programme".

Ökem, Zeynep Güldem; Çakar, Mehmet

2015-09-01

Poor health status indicators, low quality care, inequity in the access to health services and inefficiency due to fragmented health financing and provision have long been problems in Turkey's health system. To address these problems a radical reform process known as the Health Transformation Programme (HTP) was initiated in 2003. The health sector reforms in Turkey are considered to have been among the most successful of middle-income countries undergoing reform. Numerous articles have been published that review these reforms in terms of, variously, financial sustainability, efficiency, equity and quality. Evidence suggests that Turkey has indeed made significant progress, yet these achievements are uneven among its regions, and their long-term financial sustainability is unresolved due to structural problems in employment. As yet, there is no comprehensive evidence-based analysis of how far the stated reform objectives have been achieved. This article reviews the empirical evidence regarding the outcomes of the HTP during 10 years of its implementation. Strengthening the strategic purchasing function of the Social Security Institution (SSI) should be a priority. Overall performance can be improved by linking resource allocation to provider performance. More emphasis on prevention rather than treatment, with an effective referral chain, can also bring better outcomes, greater efficiency gains and contribute to sustainability.

Vector control in developed countries

PubMed Central

Peters, Richard F.

1963-01-01

The recent rapid growth of California's population, leading to competition for space between residential, industrial and agricultural interests, the development of its water resources and increasing water pollution provide the basic ingredients of its present vector problems. Within the past half-century, the original mosquito habitats provided by nature have gradually given place to even more numerous and productive habitats of man-made character. At the same time, emphasis in mosquito control has shifted from physical to chemical, with the more recent extension to biological approaches as well. The growing domestic fly problem, continuing despite the virtual disappearance of the horse, is attributable to an increasing amount of organic by-products, stemming from growing communities, expanding industries and changing agriculture. The programme for the control of disease vectors and pest insects and animals directs its major effort to the following broad areas: (1) water management (including land preparation), (2) solid organic wastes management (emphasizing utilization), (3) community management (including design, layout, and storage practices of buildings and grounds), and (4) recreational area management (related to wildlife management). It is apparent that vector control can often employ economics as an ally in securing its objectives. Effective organization of the environment to produce maximum economic benefits to industry, agriculture, and the community results generally in conditions unfavourable to the survival of vector and noxious animal species. Hence, vector prevention or suppression is preferable to control as a programme objective. PMID:20604166

The Copernicus Programme, being Europe's Earth Observation and Monitoring Programme led by the European Union, aims to provide, on a sustainable basis, reliable and timely services related to environmental and security issues. The Sentinel-3 mission forms part of the Copernicus Space Component. Its main objectives, building on the heritage and experience of the European Space Agency's (ESA) ERS and ENVISAT missions, are to measure sea-surface topography, sea- and land-surface temperature and ocean- and land-surface colour in support of ocean forecasting systems, and for environmental and climate monitoring. The series of Sentinel-3 satellites will ensure global, frequent and near-real time ocean, ice and land monitoring, with the provision of observation data in routine, long term (up to 20 years of operations) and continuous fashion, with a consistent quality and a high level of reliability and availability. The Sentinel-3 missions will be jointly operated by ESA and EUMETSAT. ESA will be responsible for the operations, maintenance and evolution of the Sentinel-3 ground segment on land related products and EUMETSAT for the marine products. The Sentinel-3 ground segment systematically acquires, processes and distributes a set of pre-defined core data products. Sentinel-3A is foreseen to be launched at the beginning of November 2015. The paper will give an overview on the mission, its instruments and objectives, the data products provided, the mechanisms to access the mission's data, and if available first results.

Analysing the magnitude, composition, evolution and trends in Colombian national spending on health, forming a proposal and making an important contribution towards knowledge re the reality of social health security. The results obtained respond to an ongoing effort to systematise and standardise the adopted methodology and update calculations and estimates for the eleven-year period during which Law 100/1993 was being reformed. Analysing the above led to identifying changes in the flow of resources and establishing objective comparisons according to current/available international standards. The project began in the Colombian Planning Department (lasting 5 years) and was then passed to the Ministry of Social Protection's Health Reform Support Programme where new institutional scope has been applied during the last four years. Perhaps the work's most important contribution consists of producing annual estimates of total public and private spending on health as a time-series, for a relatively significant period. The results confirm fulfilment of the reform's suppositions in terms of the significant amount of resources channelled to the sector, the important substitution of financing private spending for spending on health insurance, greater dynamism and the importance of public funds in financing total spending and the managing of an important segment of such resources by some of the new agents created by the reform. This contrasts with the little importance paid to spending on promotion and prevention and on public health and basic attention programmes.

Objectives To determine whether a lifestyle integrated approach to balance and strength training is effective in reducing the rate of falls in older, high risk people living at home. Design Three arm, randomised parallel trial; assessments at baseline and after six and 12 months. Randomisation done by computer generated random blocks, stratified by sex and fall history and concealed by an independent secure website. Setting Residents in metropolitan Sydney, Australia. Participants Participants aged 70 years or older who had two or more falls or one injurious fall in past 12 months, recruited from Veteran’s Affairs databases and general practice databases. Exclusion criteria were moderate to severe cognitive problems, inability to ambulate independently, neurological conditions that severely influenced gait and mobility, resident in a nursing home or hostel, or any unstable or terminal illness that would affect ability to do exercises. Interventions Three home based interventions: Lifestyle integrated Functional Exercise (LiFE) approach (n=107; taught principles of balance and strength training and integrated selected activities into everyday routines), structured programme (n=105; exercises for balance and lower limb strength, done three times a week), sham control programme (n=105; gentle exercise). LiFE and structured groups received five sessions with two booster visits and two phone calls; controls received three home visits and six phone calls. Assessments made at baseline and after six and 12 months. Main outcome measures Primary measure: rate of falls over 12 months, collected by self report. Secondary measures: static and dynamic balance; ankle, knee and hip strength; balance self efficacy; daily living activities; participation; habitual physical activity; quality of life; energy expenditure; body mass index; and fat free mass. Results After 12 months’ follow-up, we recorded 172, 193, and 224 falls in the LiFE, structured exercise, and control groups, respectively. The overall incidence of falls in the LiFE programme was 1.66 per person years, compared with 1.90 in the structured programme and 2.28 in the control group. We saw a significant reduction of 31% in the rate of falls for the LiFE programme compared with controls (incidence rate ratio 0.69 (95% confidence interval 0.48 to 0.99)); the corresponding difference between the structured group and controls was non-significant (0.81 (0.56 to 1.17)). Static balance on an eight level hierarchy scale, ankle strength, function, and participation were significantly better in the LiFE group than in controls. LiFE and structured groups had a significant and moderate improvement in dynamic balance, compared with controls. Conclusions The LiFE programme provides an alternative to traditional exercise to consider for fall prevention. Functional based exercise should be a focus for interventions to protect older, high risk people from falling and to improve and maintain functional capacity.

This study examined medical specialty selection by Nigerian resident doctors using a marketing research approach to determine the selection criteria and the role of perceptions, expected remuneration, and job placement prospects of various specialties in the selection process. Data were from the Community of residents from April 2014 to July 2014. The cohort included 200 residents, but only 171 had complete information. Data were obtained from a cross section of resident doctors in the Lagos State University Teaching Hospital and at the 2014 Ordinary General Meeting of the National Association of Resident Doctors(NARD) where representatives from over 50 Teaching hospitals in Nigeria attended. Using a client behaviour model as a framework, a tripartite questionnaire was designed and administered to residents to deduce information on their knowledge about and interests in various specialties, their opinions of sixteen specialties, and the criteria they used in specialty selection. A total of 171 (85.5%) questionnaires were returned. ln many instances, consistency between selection criteria and perceptions of a specialty were accompanied by interest in pursuing the specialty. Job security, job availability on completion of programme, duration of training and qualifying examinations were highly correlated with p value < 0.05. Results of the Principal Component Analysis show two components (with Eigen values greater than one) explaining 65.3% of the total variance. The first component had placement and training and practice related variables loaded on it while the second component was loaded with job security and financial remuneration related variables. Using marketing research concepts for medical specialty selection (Weissmanet al 2012) stipulates that choice of speciality is influenced by criteria and perception. This study shows that job security expected financial remuneration, and examination requirements for qualification are major determinants of the choice of speciality for residents.

University and college students in wealthy countries may be vulnerable to financial food insecurity. If food insecure students have suboptimal health, their ability to learn and excel in their education could be compromised. This Canadian study examined the relationship of food security status to diet and self-perceived health and academic quality among students receiving emergency food hampers from the Campus Food Bank at University of Alberta. A convenience sample of 58 students completed a survey. Of participating students, 10.3% were food secure, 44.8% were moderately food insecure and 44.8% were severely food insecure. Overall, 32.8% rated their general health as fair/poor, 27.6% rated their mental health as fair/poor and 60.3% indicated at least one adverse academic outcome of not having enough money for food. Compared to other participating students, students with severe food insecurity had a greater likelihood of fair/poor general health (odds ratios (OR) 4.03, 95% confidence intervals (CI) 1.10-14.78); fair/poor mental health (OR 4.96, 95% CI 1.28-19.19); being unable to concentrate in class or during an exam (73.1% vs 40.6%, χ 2 = 6.12, P = 0.013); relying on food hampers (34.6% vs 9.7%, χ 2 = 5.57, P = 0.018); and, consuming fewer daily fruits, vegetables and legumes (2.12 vs 2.97 cup equivalents, P = 0.009). Food insecurity compromises students' health, diet and academic quality. Campus food banks are not the solution to student hunger. Governmental and university-based programmes and policies are needed to improve the food security situation of university students. © 2016 Dietitians Association of Australia.

This research investigates whether holiday clubs have the potential to reduce food insecurity among households in the United Kingdom. We survey parents (n = 38) of children attending seven different holiday clubs to estimate the percentage of children in those programmes who come from food insecure households. Results suggest that 42% (16 out of 38 respondents) of children come from households defined as "food insecure" and 24% (9 out of 38 respondents) come from households that are "food insecure with hunger." When secure and insecure households are compared, we discover that food insecure households benefit the most from holiday clubs, which suggests that they may play an important role in mitigating household food insecurity. © 2017 The Authors.

Durban, D. M.

1984-01-01

The conversion to data base management systems processing techniques consists of three different strategies - one for each of the major stages in the development process. Each strategy was chosen for its approach in bringing about a smooth evolutionary type transition from one mode of operation to the next. The initial strategy of the indoctrination stage consisted of: (1) providing maximum access to current administrative data as soon as possible; (2) select and developing small prototype systems; (3) establishing a user information center as a central focal point for user training and assistance; and (4) developing a training program for programmers, management and ad hoc users in DBMS application and utilization. Security, the rate of the data dictionary, and data base tuning and capacity planning, and the development of a change of attitude in an automated office are issues meriting consideration.

There are strong pedagogical arguments in favor of adopting computer-based assessment. The risks of technical failure can be managed and are offset by improvements in cost-effectiveness and quality assurance capability. Academic, administrative, and technical leads at an appropriately senior level within an institution need to be identified, so that they can act as effective advocates. All stakeholder groups need to be represented in undertaking a detailed appraisal of requirements and shortlisting software based on core functionality, summative assessment life cycle needs, external compatibility, security, and usability. Any software that is a candidate for adoption should be trialed under simulated summative conditions, with all stakeholders having a voice in agreeing the optimum solution. Transfer to a new system should be carefully planned and communicated, with a programme of training established to maximize the success of adoption.

We designed and developed a control circuit for a three-dimensional (3-D) light-emitting diode (LED) array to be used in volumetric displays exhibiting full-color dynamic 3-D images. The circuit was implemented on a field-programmable gate array; therefore, pulse-width modulation, which requires high-speed processing, could be operated in real time. We experimentally evaluated the developed system by measuring the luminance of an LED with varying input and confirmed that the system works appropriately. In addition, we demonstrated that the volumetric display exhibits different full-color dynamic two-dimensional images in two orthogonal directions. Each of the exhibited images could be obtained only from the prescribed viewpoint. Such directional characteristics of the system are beneficial for applications, including digital signage, security systems, art, and amusement.

Republic of Uzbekistan is situated in the heart of Central Asia. Dangerous phenomena such as drought, flooding, mud flows, landslides and others, that are becoming frequent in conditions of climate changes, increase instability of an agricultural production, and threaten rural livelihoods. In connection with weather and climate natural disasters, these phenomena become reasons of declining food production, water contamination, and economical damages. Within the Project granted by NATO: Science for Peace and Security programme, modern advanced remote sensing technologies will be applied to perform large scale monitoring of (early) slope deformations, including Satellite SAR Interferometry (InSAR) techniques, Ground Laser Scanning for in-situ refinement of detected movements or Multibeam Echosounding for monitoring slope deformation advancement into water objects. First results involving InSAR processing of selected sites in Uzbekistan are presented within this contribution.

Background The use of information and communication technologies (ICTs) in the health service is increasing. In spite of limitations, such as lack of time and experience, the deployment of ICTs in the healthcare system has advantages which include patient satisfaction with secure messaging, and time saving benefits and utility for patients and health professionals. ICTs may be helpful as either interventions on their own or as complementary tools to help patients stop smoking. Objectives To gather opinions from both medical professionals and smokers about an email-based application that had been designed by our research group to help smoking cessation, and identify the advantages and disadvantages associated with interventions based on the utilization of ICTs for this purpose. Methods A qualitative, descriptive–interpretative study with a phenomenological perspective was performed to identify and interpret the discourses of the participating smokers and primary healthcare professionals. Data were obtained through two techniques: semi-structured individual interviews and discussion groups, which were recorded and later systematically and literally transcribed together with the interviewer’s notes. Data were analyzed with the ATLAS TI 6.0 programme. Results Seven individual interviews and four focal groups were conducted. The advantages of the application based on the email intervention designed by our research group were said to be the saving of time in consultations and ease of access for patients who found work timetables and following a programme for smoking cessation incompatible. The disadvantages were thought to be a lack of personal contact with the healthcare professional, and the possibility of cheating/ self-deception, and a greater probability of relapse on the part of the smokers. Conclusions Both patients and healthcare professionals viewed the email-based application to help patients stop smoking as a complementary aid to face-to-face consultations. Nevertheless, ICTs could not substitute personal contact in the smoking cessation programme. PMID:26340346

Following approximately 10 years from the beginning of Iran's national Health Technology Assessment (HTA) programme, the present study aims to evaluate its success by examining the impact of HTA and identifying the determinant factors leading to the implementation of HTA report results. The triangulation method was employed herein. HTA reports were initially identified and their impact and determinant factors were then examined from the perspectives of both researchers (by preparing a questionnaire according to the Payback model and sending it to HTA principle investigators) and stakeholders (semi-structured interviews held with each HTA stakeholder). Simultaneously, the quality of the HTA reports was examined with relevant critical appraisal checklists. The impact of 19 equipment technologies and four pharmaceutical technologies were assessed in this study. Twenty researchers replied (response rate, 86.96%) to the questionnaire on the impact of HTA reports from the researcher's perspective. To assess the impact of HTA reports from the stakeholder's perspective, seven policy-makers were chosen and interviewed as the main target audience. The most common step taken to disseminate the results of the HTA projects was publication. Conducting the HTA had taught researchers and their colleagues' new skills and had facilitated the securing of research grants from other organisations. Most reports had used the systematic review method but the relevant details had been scarcely presented regarding outcomes, costs and analysis. The greatest impact of HTA reports on decision-making had been on policy-makers providing and allocating finances. Barriers in stewardship, identification and prioritisation of topics, performance and dissemination of HTA results were the main barriers of implementing HTAs. In most aspects, the status of HTA impact reports need improvement. Thus far, the barriers and facilitators of the HTA programme in Iran have been investigated in other studies. These findings should be pooled to reach a solution that can be actively applied to the health system to improve the status quo of HTA in Iran.

The management of research data is now a major challenge for research organisations. Vast quantities of born-digital data are being produced in a wide variety of forms at a rapid rate in universities. This paper analyses the contribution of academic libraries to research data management (RDM) in the wider institutional context. In particular it: examines the roles and relationships involved in RDM, identifies the main components of an RDM programme, evaluates the major drivers for RDM activities, and analyses the key factors influencing the shape of RDM developments. The study is written from the perspective of library professionals, analysing data from 26 semi-structured interviews of library staff from different UK institutions. This is an early qualitative contribution to the topic complementing existing quantitative and case study approaches. Results show that although libraries are playing a significant role in RDM, there is uncertainty and variation in the relationship with other stakeholders such as IT services and research support offices. Current emphases in RDM programmes are on developments of policies and guidelines, with some early work on technology infrastructures and support services. Drivers for developments include storage, security, quality, compliance, preservation, and sharing with libraries associated most closely with the last three. The paper also highlights a 'jurisdictional' driver in which libraries are claiming a role in this space. A wide range of factors, including governance, resourcing and skills, are identified as influencing ongoing developments. From the analysis, a model is constructed designed to capture the main aspects of an institutional RDM programme. This model helps to clarify the different issues involved in RDM, identifying layers of activity, multiple stakeholders and drivers, and a large number of factors influencing the implementation of any initiative. Institutions may usefully benchmark their activities against the data and model in order to inform ongoing RDM activity.

Community pharmacy minor ailment services in England: Pharmacy stakeholder perspectives on the factors affecting sustainability.

Self-care advice and management of minor ailments have long been provided in community pharmacies across England. However, formal pharmacy minor ailment service provision is geographically variable and has yet to gain recognition and political support as a valued sustainable service for nationwide adoption and commissioning. To investigate the sustainability potential of pharmacy minor ailment services from the perspective of community pharmacy stakeholders within the North East of England. A mixed methods approach was adopted to survey and interview stakeholders from the North East of England who commission; provide; and/or represent groups influencing the design, delivery and investment in community pharmacy clinical and public health services. The 40-item Programme Sustainability Assessment Tool, a validated instrument to assess a public health programme's capacity for sustainability across eight domains, was administered to fifty-three stakeholders, identified from a pharmacy minor ailments showcase event. The same stakeholders were invited for a semi-structured interview to explore issues further. Interviews were audio-recorded, transcribed verbatim, and underwent framework analysis. Forty-two (79.2% response rate) stakeholders representing commissioning, provider and influencing (e.g. Local Professional Network) organisations completed the assessment tool. Pharmacy minor ailment services were rated as unsustainable across the majority of the domains. Elements within the domain 'Partnerships' demonstrated potential for sustainability. Stakeholder interviews provided detailed explanation for the low scoring sustainability domains, highlighting the multifaceted challenges threatening these services. The Programme Sustainability Assessment Tool allowed stakeholders to evaluate the potential of pharmacy minor ailment services in England. Follow-up interviews highlighted that initial design and implementation of services was poorly conceived and lacked evidence, thereby impeding the services' sustainability. There are many challenges facing a widespread provision of pharmacy ailment services, but it is clear the profession needs to be clear on the service objectives to secure future interest and investment.

The important role that monitoring plays in advancing global health is well established. However, the role of social monitoring as a tool for addressing social determinants of health (SDH) and health equity-focused policies remains under-researched. This paper assesses the extent and ways in which New Zealand's (NZ) Social Reports (SRs) supported a SDH- and health equity-oriented policy programme nationally over the 2000-2008 period by documenting the SRs' history and assessing its impact on policies across sectors in government and civil society. We conducted key-informant interviews with five senior policy-makers and an e-mail survey with 24 government and civil society representatives on SRs' history and policy impact. We identified common themes across these data and classified them accordingly to assess the intensity of the reports' use and their impact on SDH- and health equity-focused policies. Bibliometric analyses of government publications and media items were undertaken to empirically assess SRs' impact on government and civil society. SRs in NZ arose out of the role played by government as the "benevolent social welfare planner" and an understanding of the necessity of economic and social security for "progress". The SRs were linked to establishing a government-wide programme aimed at reducing inequalities. They have been used moderately to highly in central and local government and in civil society, both within and outside the health sector, but have neither entered public treasury and economic development departments nor the commercial sector. The SRs have not reached the more universal status of economic indicators. However, they have had some success at raising awareness of, and have stimulated isolated action on, SDH. The NZ case suggests that national-level social monitoring provides a valuable tool for raising awareness of SDH across government and civil society. A number of strategies could improve social reports' effectiveness in stimulating action on SDH. Copyright © 2013 Elsevier Ltd. All rights reserved.

Caregiver burden among adults caring for orphaned children in rural South Africa

Kidman, Rachel; Thurman, Tonya R.

2014-01-01

The AIDS epidemic has created an unprecedented number of orphans. While largely absorbed by extended family, this additional responsibility can weigh heavily on their caregivers. The concept of caregiver burden captures multiple dimensions of well-being (e.g., physical, social and psychological). Measuring the extent and determinants of caregiving burden can inform the design of programmes to ease the negative consequences of caregiving. This study uses the baseline data from a study assessing interventions for orphans and vulnerable adolescents in the Eastern Cape, South Africa. Orphan caregivers (n = 726) completed an adapted version of the 12-item Zarit Burden Interview. In addition to basic caregiver and household demographics, the survey also collected information on AIDS-related illness and recent deaths. Descriptive data are presented, followed by multivariate Poisson regression models to explore factors associated with caregiver burden. Approximately 40% of caregivers reported high levels of orphan caregiving burden. Feelings of stress and inadequacy concerning their care responsibilities as well as anger towards the child were common. Household food insecurity was the most important predictor of orphan caregiving burden (marginal effect = 7.82; p < 0.001 for those reporting severe hunger); income was also a significant determinant. When other AIDS impacts were added to the model, only the AIDS-related illness of the caregiver was significantly associated with burden (marginal effect = 3.77; p < 0.001). This study suggests that caregivers with economic vulnerability and those struggling with their own AIDS-related illness feel most overburdened. These findings are particularly relevant to service providers who must identify caregivers in need of immediate assistance and allocate limited resources effectively. To alleviate caregiver burden, programmes must foster greater economic security (e.g., by facilitating access to social grants or directly providing cash transfers) and coordinate services with home-based care programmes serving the chronically ill.

The Canadian partnership---Royal Astronomical Society of Canada (RASC), Fédération des astronomes amateurs du Québec (FAAQ), and Canadian Astronomical Society (CASCA)---is implementing elements designed to offer an engaging astronomy experience to every Canadian during 2009. Our goals for all themes envision creating long-lasting impacts, especially in the education and inspiration of youth. Wherever possible we seek to leverage and extend existing programmes, and we aim to provide materials in both English and French. To make IYA2009 successful, both the RASC and FAAQ have committed significant funds over and above their extensive in-kind contributions of volunteer time. Through the `Galileo Moment' theme we aim to get more than one million Canadians to look through a telescope, or participate in cultural and outreach events that bring a strong sense of personal astronomical discovery. An Astronomy Kit of physical and/or virtual components is under development. A partnership led by Cape Breton University faculty proposes extensive participation by Canada's Aboriginal Communities, including a series of activities designed to bring elders and youth together. Reinvigoration of the RASC's long-standing efforts to create Dark Sky Preserves is another cross-cutting theme. Outreach programmes of Canada's major planetaria and science centres, a national astronomy lecture series, as well as partnerships with arts and cultural organizations, offer hopes of reaching both traditional and non-traditional audiences in fun, engaging ways. Individual volunteer efforts are emerging to implement in high-traffic locales From the Earth to the Universe astronomical image exhibits from material developed by both IAU and Canadian curatorial teams. Our proposal for commemorative stamps has been accepted, and efforts are underway to secure commemorative coins, as well. The Canadian Space Agency has agreed to launch in 2010 a DVD with names of the Canadians who register their Galileo Moment experience. Fund raising is underway in earnest.

Introduction Making change towards child and family-based and coordinated services is critical to improve quality, outcomes and value. The Let’s Talk about Children (LTC) approach, which consists of brief psychoeducational discussions with parents of kindergarten-aged and school-aged children, has been launched as a municipality-specific programme in the Council of Oulu Region. The aim of this paper is to present a protocol of an ecological study evaluating the group-specific effects of an intervention about LTC activities in a geographically defined population. The programme is designed to promote children’s socioemotional well-being. Methods and analysis A quasi-experimental ecological study protocol is implemented to evaluate whether systematic LTC practices improve children’s well-being. A multi-informant setting covers 30 municipalities in northern Finland and involves all the municipal teachers, social and healthcare workers. In each municipality, a Local Management Team is responsible for implementing the LTC programme and collecting the annual data of LTC discussions and network meetings. The outcome data are retrieved from child welfare statistics and hospital registers. The population data, child welfare statistics and referrals to hospitals was retrieved at baseline (2014), and will be retrieved annually. Furthermore, the annual data of LTC discussions and network meetings will be collected of the years 2015–2018. Ethics and dissemination The study design has been approved by the management of the Oulu University Hospital in accordance with the guidelines given by The Regional Ethics Committee of the Northern Ostrobothnia Hospital District in Oulu, Finland. All data are treated and implemented according to national data security laws. Study findings will be disseminated to provincial and municipal partners, collaborative community groups and the research and development community. The Let’s Talk about Children Evaluation study databases will guide future regional development action and policies. PMID:28710220

The way to a man's heart is through his stomach?: a mixed methods study on causal mechanisms through which cash and in-kind food transfers decreased intimate partner violence.

Intimate partner violence (IPV) is highly prevalent and has detrimental effects on the physical and mental health of women across the world. Despite emerging evidence on the impacts of cash transfers on intimate partner violence, the pathways through which reductions in violence occur remain under-explored. A randomised controlled trial of a cash and in-kind food transfer programme on the northern border of Ecuador showed that transfers reduced physical or sexual violence by 30 %. This mixed methods study aimed to understand the pathways that led to this reduction. We conducted a mixed methods study that combined secondary analysis from a randomised controlled trial relating to the impact of a transfer programme on IPV with in-depth interviews and focus group discussions with male and female beneficiaries. A sequential analysis strategy was followed, whereby qualitative results guided the choice of variables for the quantitative analysis and qualitative insights were used to help interpret the quantitative findings. We found qualitative and quantitative evidence that the intervention led to reductions in IPV through three pathways operating at the couple, household and individual level: i) reduced day-to-day conflict and stress in the couple; ii) improved household well-being and happiness; and iii) increased women's decision making, self-confidence and freedom of movement. We found little evidence that any type of IPV increased as a result of the transfers. While cash and in-kind transfers can be important programmatic tools for decreasing IPV, the positive effects observed in this study seem to depend on circumstances that may not exist in all settings or programmes, such as the inclusion of a training component. Moreover, the programme built upon rather than challenged traditional gender roles by targeting women as transfer beneficiaries and framing the intervention under the umbrella of food security and nutrition - domains traditionally ascribed to women. Transfers destined for food consumption combined with nutrition training reduced IPV among marginalised households in northern Ecuador. Evidence suggests that these reductions were realised by decreasing stress and conflict, improving household well-being, and enhancing women's decision making, self-confidence and freedom of movement.

The need for theory evaluation in global citizenship programmes: The case of the GCSA programme.

PubMed

Goodier, Sarah; Field, Carren; Goodman, Suki

2018-02-01

Many education programmes lack a documented programme theory. This is a problem for programme planners and evaluators as the ability to measure programme success is grounded in the plausibility of the programme's underlying causal logic. Where the programme theory has not been documented, conducting a theory evaluation offers a foundational evaluation step as it gives an indication of whether the theory behind a programme is sound. This paper presents a case of a theory evaluation of a Global Citizenship programme at a top-ranking university in South Africa, subsequently called the GCSA Programme. This evaluation highlights the need for documented programme theory in global citizenship-type programmes for future programme development. An articulated programme theory produced for the GCSA Programme, analysed against the available social science literature, indicated it is comparable to other such programmes in terms of its overarching framework. What the research found is that most other global citizenship programmes do not have an articulated programme theory. These programmes also do not explicitly link their specific activities to their intended outcomes, making demonstrating impact impossible. In conclusion, we argue that taking a theory-based approach can strengthen and enable outcome evaluations in global citizenship programmes. Copyright © 2017. Published by Elsevier Ltd.

SeaDataNet II - Second phase of developments for the pan-European infrastructure for marine and ocean data management

Schaap, Dick M. A.; Fichaut, Michele

2013-04-01

The second phase of the project SeaDataNet started on October 2011 for another 4 years with the aim to upgrade the SeaDataNet infrastructure built during previous years. The numbers of the project are quite impressive: 59 institutions from 35 different countries are involved. In particular, 45 data centers are sharing human and financial resources in a common efforts to sustain an operationally robust and state-of-the-art Pan-European infrastructure for providing up-to-date and high quality access to ocean and marine metadata, data and data products. The main objective of SeaDataNet II is to improve operations and to progress towards an efficient data management infrastructure able to handle the diversity and large volume of data collected via the Pan-European oceanographic fleet and the new observation systems, both in real-time and delayed mode. The infrastructure is based on a semi-distributed system that incorporates and enhance the existing NODCs network. SeaDataNet aims at serving users from science, environmental management, policy making, and economical sectors. Better integrated data systems are vital for these users to achieve improved scientific research and results, to support marine environmental and integrated coastal zone management, to establish indicators of Good Environmental Status for sea basins, and to support offshore industry developments, shipping, fisheries, and other economic activities. The recent EU communication "MARINE KNOWLEDGE 2020 - marine data and observation for smart and sustainable growth" states that the creation of marine knowledge begins with observation of the seas and oceans. In addition, directives, policies, science programmes require reporting of the state of the seas and oceans in an integrated pan-European manner: of particular note are INSPIRE, MSFD, WISE-Marine and GMES Marine Core Service. These underpin the importance of a well functioning marine and ocean data management infrastructure. SeaDataNet is now one of the major players in informatics in oceanography and collaborative relationships have been created with other EU and non EU projects. In particular SeaDataNet has recognised roles in the continuous serving of common vocabularies, the provision of tools for data management, as well as giving access to metadata, data sets and data products of importance for society. The SeaDataNet infrastructure comprises a network of interconnected data centres and a central SeaDataNet portal. The portal provides users not only background information about SeaDataNet and the various SeaDataNet standards and tools, but also a unified and transparent overview of the metadata and controlled access to the large collections of data sets, managed by the interconnected data centres. The presentation will give information on present services of the SeaDataNet infrastructure and services, and highlight a number of key achievements in SeaDataNet II so far.

Background In recent years, global public health security has been threatened by zoonotic disease emergence as exemplified by outbreaks of H5N1 and H1N1 influenza, SARS, and most recently Ebola and Zika. Additionally, endemic zoonoses, such as rabies, burden countries year after year, placing demands on limited finances and personnel. To survey the baseline status of the emerging and endemic zoonoses programmes of the Latin American and the Caribbean (LAC) countries, the Pan American Health Organization (PAHO) conducted a survey of priority emerging and endemic zoonoses, countries´ prioritization criteria and methodologies, and suggestions to strengthen countries capacities and regional approaches to zoonoses control. Methods A fillable online questionnaire was sent to the zoonoses programme managers of the Ministries of Health (MOH) and Ministries of Agriculture (MAg) of 33 LAC countries from January to April of 2015. The questionnaire comprised 36 single, multiple choice and open-ended questions to inform the objectives of the survey. A descriptive exploratory analysis was completed. Results Fifty-four ministries (26 MOH, 25 MAg, and 3 combined responses) in 31 LAC countries responded to the survey. Within the ministries, 22 (85%) MOH, 5 (20%) MAg, and 2 (67%) combined entities indicated they had specialized zoonoses units. For endemic zoonoses, 32 of 54 ministries responded that they conduct formal prioritization exercises, most of them annually (69%). The three priority endemic zoonoses for the MOHs were leptospirosis, rabies, and brucellosis while the three priorities for the MAgs were brucellosis, rabies, and tuberculosis. Diagnosis for rabies and leptospirosis were cited as the capacities most in need of development. The most needed cross-cutting capacity was coordination between stakeholders. For emerging zoonoses, 28 ministries performed formal prioritization exercises. The top prioritization criteria were probability of introduction into the country and impact. The three priority emerging zoonoses for the MOHs were Ebola viral disease, avian influenza, and Chikungunya while for the MAgs were avian influenza, bovine spongiform encephalopathy and West Nile virus disease. Surveillance for avian influenza and Ebola, and diagnosis for BSE were quoted as the capacities most needed. For all zoonoses, the majority of respondents (69%) ranked their relationship with the other Ministry as productive or very productive, and 31% minimally productive. Many countries requested a formal regional network, better regional communication and collaboration, and integrated surveillance. Conclusions The survey is the first comprehensive effort to date to inform the status of zoonoses programmes in LAC. The information collected here will be used to develop a regional strategy for zoonoses (both endemic and emerging), increase efforts, advocacy, and promote prompt identification and management of EIDs and improvement of endemic programmes.

Traditionally, record linkage techniques have required that all the identifying data in which links are sought be revealed to at least one party, often a third party. This necessarily invades personal privacy and requires complete trust in the intentions of that party and their ability to maintain security and confidentiality. Dusserre, Quantin, Bouzelat and colleagues have demonstrated that it is possible to use secure one-way hash transformations to carry out follow-up epidemiological studies without any party having to reveal identifying information about any of the subjects - a technique which we refer to as "blindfolded record linkage". A limitation of their method is that only exact comparisons of values are possible, although phonetic encoding of names and other strings can be used to allow for some types of typographical variation and data errors. A method is described which permits the calculation of a general similarity measure, the n-gram score, without having to reveal the data being compared, albeit at some cost in computation and data communication. This method can be combined with public key cryptography and automatic estimation of linkage model parameters to create an overall system for blindfolded record linkage. The system described offers good protection against misdeeds or security failures by any one party, but remains vulnerable to collusion between or simultaneous compromise of two or more parties involved in the linkage operation. In order to reduce the likelihood of this, the use of last-minute allocation of tasks to substitutable servers is proposed. Proof-of-concept computer programmes written in the Python programming language are provided to illustrate the similarity comparison protocol. Although the protocols described in this paper are not unconditionally secure, they do suggest the feasibility, with the aid of modern cryptographic techniques and high speed communication networks, of a general purpose probabilistic record linkage system which permits record linkage studies to be carried out with negligible risk of invasion of personal privacy.

The European Space Agency (ESA) has twenty two Member States with common goals of engaging in European space activities. However, the various Member States have a variety of governance structures, strategic priorities regarding space and other sectorial areas depending on their cultural and geopolitical aspirations. The Nordic countries, namely Denmark, Finland, Norway and Sweden, have similarities which result often in common geopolitical and cultural aspects. These in turn shape their respective priorities and interests in setting up their policies in a number of sectorial areas like shipping and fisheries, energy, immigration, agriculture, security and defence, infrastructures, climate change and the Arctic. Space technology, navigation, earth observation, telecommunication and integrated applications can assist the Nordic countries in developing, implementing and monitoring policies of common interest. This paper provides an in-depth overview and a comprehensive assessment of these common interests in policy areas where space can provide support in their realisation. The first part provides a synthesis of the Nordic countries respective priorities through analysing their government programmes and plans. The priorities are classified according to the six areas of sustainability: energy, environment and climate change, transport, knowledge and innovation, natural resources (fisheries, agriculture, forestry, mining, etc), and security and external relations. Although the national strategies present different national perspectives, at the same time, there are a number of similarities when it comes to overall policy objectives in a number of areas such as the Arctic and climate change. In other words, even though the Arctic plays a different role in each country's national context and there are clear differences as regards geography, access to resources and security policies, the strategies display common general interest in sustainable development and management of resources, protection of the environment, international cooperation and regional security. The second part of this paper focuses on the national space strategies and indicates the main priorities and trends. The priorities vary from one country to the other and can include science, navigation, earth observation, human space flight, launchers, technology development, and/or applications. The motivation for investing in space activities also change (e.g. international cooperation, industrial competitiveness, societal benefits, job creation).

An advanced surveillance/security system is being developed for unattended 24/7 image acquisition and automated detection, discrimination, and tracking of humans and vehicles. The low-light video camera incorporates an electron multiplying CCD sensor with a programmable on-chip gain of up to 1000:1, providing effective noise levels of less than 1 electron. The EMCCD camera operates in full color mode under sunlit and moonlit conditions, and monochrome under quarter-moonlight to overcast starlight illumination. Sixty frame per second operation and progressive scanning minimizes motion artifacts. The acquired image sequences are processed with FPGA-compatible real-time algorithms, to detect/localize/track targets and reject non-targets due to clutter under a broad range of illumination conditions and viewing angles. The object detectors that are used are trained from actual image data. Detectors have been developed and demonstrated for faces, upright humans, crawling humans, large animals, cars and trucks. Detection and tracking of targets too small for template-based detection is achieved. For face and vehicle targets the results of the detection are passed to secondary processing to extract recognition templates, which are then compared with a database for identification. When combined with pan-tilt-zoom (PTZ) optics, the resulting system provides a reliable wide-area 24/7 surveillance system that avoids the high life-cycle cost of infrared cameras and image intensifiers.

Typically, commercial sensor nodes are equipped with MCUsclocked at a low-frequency (i.e., within the 4–12 MHz range). Consequently, executing cryptographic algorithms in those MCUs generally requires a huge amount of time. In this respect, the required energy consumption can be higher than using a separate accelerator based on a Field-programmable Gate Array (FPGA) that is switched on when needed. In this manuscript, we present the design of a cryptographic accelerator suitable for an FPGA-based sensor node and compliant with the IEEE802.15.4 standard. All the embedded resources of the target platform (Xilinx Artix-7) have been maximized in order to provide a cost-effective solution. Moreover, we have added key negotiation capabilities to the IEEE 802.15.4 security suite based on Elliptic Curve Cryptography (ECC;. Our results suggest that tailored accelerators based on FPGA can behave better in terms of energy than contemporary software solutions for motes, such as the TinyECC and NanoECC libraries. In this regard, a point multiplication (PM) can be performed between 8.58- and 15.4-times faster, 3.40- to 23.59-times faster (Elliptic Curve Diffie-Hellman, ECDH) and between 5.45- and 34.26-times faster (Elliptic Curve Integrated Encryption Scheme, ECIES). Moreover, the energy consumption was also improved with a factor of 8.96 (PM). PMID:23899936
