    UNESCO's International Hydrological Programme (IHP) is the only intergovernmental scientific program of the UN system on freshwater having a global scope. Since its inception in 1975, IHP has been at the forefront of international cooperation on water research and management, bringing together scientists, engineers, policy- makers, managers, and stakeholders. Currently there are over 160 National Committees for the IHP, including the US. During six successive phases, IHP has evolved into a transdisciplinary, action-oriented and policy- relevant program with a strong scientific core responding to the needs of the Member States. This presentation will address the concepts underpinning the strategic plan of the seventh phase of IHP (2008-2013) and the proposed lines of action. Adaptation to the impacts of global changes on river basins and aquifer systems is a theme central to this phase. Global changes associated with climate, demographic factors and modifications in land use, among other factors, can have significant impacts on the hydrological cycle and on water resources. Due to the global character of such changes, its potential interaction with the hydrological cycle, and the transboundary nature of many river basins and aquifers, international cooperation is essential to improve our understanding and to efficiently address the challenges posed to water resources. During IHP-VII, particularly stressed and/or vulnerable areas (i.e. arid and semi-arid regions, the Polar regions, glaciated mountainous, urban areas and coastal regions) will be assessed, with the aim of supporting the development of mitigation and adaptation strategies by Member States and policies based on institutional synergies to diminish stresses on water resources. Strengthening water governance for sustainability is another thematic concentration, emphasizing the need of society to be able to respond adequately to the critical freshwater challenges. Lessons learned from the cross

    The combination of climate change, population growth, and growing use of irrigated agriculture has resulted in increased stress on water resources around the world. The problem is worsened with the expansion of population centers in water-scarce regions, for example in the southwestern United States, central Mexico, along the Mediterranean coast of Africa, southern India, and southeast Australia. As such, water has emerged as a global issue that requires international cooperation on assessment, research, and management. Entities such as the UNESCO International Hydrological Programme (IHP) focus activities on water research, water resources management, education, and capacity-building. The U.S. National Committee for UNESCO IHP, reorganized in 2006, includes members of the U.S. National Commission for UNESCO, U.S. government agencies, academic institutions, and external organizations with expertise in hydrology and hydraulics. The responsibilities of the U.S. National Committee for IHP are to: provide programmatic advice to IHP; assist in supporting other UNESCO water resources activities; represent U.S. domestic and international water activities to UNESCO; support IHP training, research, and capacity building efforts from a U.S. perspective; recommend and support the participation of other U.S. water programs in the IHP; and advise the U.S. Government on its participation in UNESCO and the IHP. Working through its membership, the U.S. National Committee for UNESCO IHP seeks to build improved relationships and involve and provide opportunities to the U.S. hydrological community.

    This paper presents the major water challenges at global, regional and local levels, including the need to adapt to climate change. It relates how the International Hydrological Programme (IHP) - an intergovernmental scientific programme - will respond in its Eighth Phase to the water-related risks and seize potential opportunities, thereby contributing to ensure Water Security at all levels. The Member States of UNESCO IHP periodically define priorities for research, technological development, innovation and education. To implement the priorities in a coordinated manner, the Member States can count on the team and the projects of IHP based at UNESCO, as well as on the "UNESCO Water Family|, consisting to date of a Category 1 centre UNESCO-IHE located in the Netherlands; the World Water Assessment Programme, based in Italy, which produces the World Water Development Report of the United Nations; 30 Category 2 water centres under the auspices of UNESCO; and 35 water chairs in various parts of the world. Governments can access the powerful network of the UNESCO Water Family through IHP and its Intergovernmental Council.

    In a wide International Context characterised not only by the economical development but also by the social, cultural, political and individual development, we witness more and more to a exchange between the developed and the developing countries, which can be translated especially in the migration of the work force. In theory, all countries are either countries of origin either countries of transit or destination, and they are all responsible for the rights of migrant workers by promoting the rights, by monitoring and by preventing the abusive conditions. The process of migration of the workforce can be divided into three stages: the first coincides with the period prior to departure, the second is represented by the aftermath of the departure and the period of stay in the country of destination, the third stage corresponds to the return in the country of origin. The workers must be protected throughout this process by the international organizations that perform the catalytic role of communication and exchange between countries, for the only purpose of protecting the rights of immigrant and/or immigrants workers. The responsibility for the protection of workers is divided among the various players in the International Labour Organisation. Every country has to apply measures according to the international standards regarding workers' rights, standards that guide the various countries in the formulation and implementation of their policies and legislation. These standards are suggested by International Conventions, the ILO Conventions and other international instruments such as the human rights instrument. There has been a big step forward once the ILO Fundamental Conventions and Conventions on Migrant Workers where implemented and this implementation represented the use of the Guidelines "ILO Multilateral Framework on Labour Migration".

    PEST is tool based on minimization of an objective function related to the root mean square error between the model output and the measurement. We use "singular value decomposition", section of the PEST control file, and Tikhonov regularization method for successfully estimation of model parameters. The PEST sometimes failed if inverse problems were ill-posed, but (SVD) ensures that PEST maintains numerical stability. The choice of the initial guess for the initial parameter values is an important issue in the PEST and need expert knowledge. The flexible nature of the PEST software and its ability to be applied to whole catchments at once give results of calibration performed extremely well across high number of sub catchments. Use of parallel computing version of PEST called BeoPEST was successfully useful to speed up calibration process. BeoPEST employs smart slaves and point-to-point communications to transfer data between the master and slaves computers. The HBV-light model is a simple multi-tank-type model for simulating precipitation-runoff. It is conceptual balance model of catchment hydrology which simulates discharge using rainfall, temperature and estimates of potential evaporation. Version of HBV-light-CLI allows the user to run HBV-light from the command line. Input and results files are in XML form. This allows to easily connecting it with other applications such as pre and post-processing utilities and PEST itself. The procedure was applied on hydrological model of Savinja catchment (1852 km2) and consists of twenty one sub-catchments. Data are temporary processed on hourly basis.

    There are several notable gaps in our current level of understanding of Arctic hydrological systems. At the same time, rapidly emerging data sets, technologies, and modeling resources provide us with an unprecedented opportunity to move substantially forward. The Arctic Community-Wide Hydrological Analysis and Monitoring Program (Arctic-CHAMP), funded by NSF/ARCSS, was established to initiate a major effort to improve our current monitoring of water cycle variables, and to foster collaboration with the many relevant U.S. and international arctic research initiatives. These projects, funded under ARCSS through the ‘Freshwater Integration (FWI) study’, links CHAMP, the Arctic/Subarctic Ocean Fluxes (ASOF) Programme, and SEARCH. As part of the overall synthesis and integration efforts of the NSF-ARCSS Freshwater Integration (FWI) study, the program carried-out a major International Synthesis Capstone Workshop in Fall 2009 as an International Polar Year (IPY) affiliated meeting. The workshop, "Synthesizing International Understanding of Changes in the Arctic Hydrological System,” was held 30 September to 4 October 2009 in Stockholm at the Beijer Auditorium of the Royal Swedish Academy. The workshop was sponsored by the NSF-ARCSS Arctic-CHAMP Science Management Office (City College of New York / Univ. of New Hampshire), the International Study of Arctic Change (ISAC), and the International Arctic Research Center (IARC; Univ. of Alaska Fairbanks). The overarching goals of the meeting were to stage a post-IPY lessons-learned workshop with co-equal numbers of FWI, IPY, and ICARP-II researchers, using insights from recent scientific findings, data, and strategies to afford synthesis. The workshop aimed to: (1) take stock of recent advances in our understanding of changes in the Arctic hydrological system; (2) identify key remaining research gaps / unanswered questions; and (3) gather insight on where to focus future research efforts/initiatives (nationally and

    Potential internal contamination of workers is monitored by periodic bioassay measurements interpreted in terms of intake and committed effective dose by the use of biokinetic and dosimetric models. After a prospective evaluation of exposure at a workplace, a suitable monitoring programme can be defined by choosing adequate measurement techniques and frequency. In this study, the sensitivity of a programme is evaluated by the minimum intake and dose, which may be detected with a given level of confidence by taking into account uncertainties on exposure conditions and measurements. This is made for programme optimisation, which is performed by comparing the sensitivities of different alternative programmes. These methods were applied at the AREVA NC reprocessing plant and support the current monitoring programme as the best compromise between the cost of the measurements and the sensitivity of the programme.

    The prevalence and nature of resident teaching skills improvement programmes (TSIP) are unknown. Although residents perceive themselves as important teachers of students, there is little information on how programme directors (PDs) view residents as teachers. A comprehensive questionnaire was sent to all 428 US internal medicine PDs in December 1990, of which 60% (n = 259) responded. Of the 259 responding programmes, only 20% (n = 51) had TSIPs. Characteristics of TSIPs were not uniform. Mean instructional time was 9 hours (range, 1-24 hours). The teacher most frequently utilized to develop and facilitate the TSIP was the PD. PDs from residencies with a TSIP indicated more strongly than PDs without a TSIP that residents contributed to students' learning. Fifty-one per cent of TSIPs required residents to attend. Evaluation/feedback as a teaching method was the most common topic covered in TSIPs. Long-term assessment of teaching skills after programme participation was done in 15% of TSIPs. Although PDs value the resident's role as teacher, current TSIPs in internal medicine residencies are few in number and lack standardization. PDs' attitudes probably influence whether residents are taught teaching skills and whether teaching skills are evaluated. Further investigation of appropriate curriculum for TSIPs and assessment of long-term effectiveness of TSIPs are needed. PMID:8336577

    Rycroft, M. J.

    The ISU's Master of Space Studies (MSS) programme is a new, unique and interdisciplinary postgraduate course of eleven months duration. It is designed for those who will lead and work in the international space programmes of the next century. It considers not only many aspects of the space sciences and their applications, but also most engineering, business, management, policy and law issues relevant to the activities of both space agencies and space industries. In the first term, fundamental issues are covered, and MSS participants from many countries around the world select some topics of their choice; within the sciences, attention is focused on basic physics, the space environment and life sciences. In the second and third terms, advanced subjects ranging from astronomy to planetary sciences, microgravity sciences, telecommunications and remote sensing of the Earth's surface and atmosphere are available. For two months in the second term, each participant carries out a project at an affiliate campus or an associated institution, and prepares a written report on this. Throughout the year, all participants play an active part in a team design project on a chosen theme; a substantial written report is prepared, and the results are also presented orally. Thus the aim of the MSS programme is to educate space generalists, yet generalists who are knowledgeable in all the relevant disciplines, including science.

    International collaboration between institutes and universities working and studying the same transboundary basin is needed for consensus building around possible effects of climate change and climate adaptation measures. Education, experience and expert knowledge of the hydrological community have resulted in the development of a great variety of model concepts, calibration and analysis techniques. Intercomparison could be a first step into consensus modeling or an ensemble based modeling strategy. Besides these practical objectives, such an intercomparison offers the opportunity to explore different ranges of models and learn from each other, hopefully increasing the insight into the hydrological processes that play a role in the transboundary basin. In this experiment, different international research groups applied their rainfall-runoff model in the Ourthe, a Belgium sub-catchment of the Meuse. Data preparation involved the interpolation of hourly precipitation station data collected and owned by the Service Public de Wallonie1 and the freely available E-OBS dataset for daily temperature (Haylock et al., 2008). Daily temperature was disaggregated to hourly values and potential evaporation was derived with the Hargreaves formula. The data was made available to the researchers through an FTP server. The protocol for the modeling involved a split-sample calibration and validation for pre-defined periods. Objective functions for calibration were fixed but the calibration algorithm was a free choice of the research groups. The selection of calibration algorithm was considered model dependent because lumped as well as computationally less efficient distributed models were used. For each model, an ensemble of best performing parameter sets was selected and several performance metrics enabled to assess the models' abilities to simulate discharge. The aim of this experiment is to identify those model components and structures that increase model performance and may best

    chairing the ILWS steering committee for the first two years. “There is a clear need to study the Sun and its interaction with the Earth” he says, “ and it is too big a job for a single space agency to cope with.” Notes to editors The new International Living With a Star (ILWS) programme builds upon a previous international framework between Europe, Japan, Russia (formerly the Soviet Union), and the United States to study the Sun and its effects on Earth. That framework was the International Solar Terrestrial Physics (ISTP) programme. The SOHO and Cluster missions were part of ESA’s contribution. For ILWS, the Canadian Space Agency has joined the collaboration. A ‘kick-off’ meeting between the space agencies involved in ILWS was held on 4-6 September 2002 in Washington DC, United States. An international steering committee of representatives from those agencies will now supervise the programme. The committee comprises five space agencies: the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), Japan's Institute for Space and Astronautical Science (ISAS), the Russian Aviation and Space Agency (Rosaviacosmos), and the Canadian Space Agency (CSA). There will be an ILWS Working Group to coordinate special projects. More than 20 space agencies have announced their participation in the first Working Group meeting, scheduled to take place in Nice, France, on 14 -15 April 2003. Contributions from the various space agencies include missions, payloads, subsystems, launch or tracking services, rockets, balloons, and open access to data sources.

    The International Council of Nurses (ICN) is a federation of 129 national nurses associations. The International Classification for Nursing Practice (ICNP) is a programme of the ICN. The purpose of this paper is to describe the development and maintenance processes of the ICNP Programme that are used to increase participation. These include processes by which the ICNP was and continues to be developed, tested, distributed and implemented worldwide, with emphasis on the current version, ICNP Version 1.0. The ICNP is a unified nursing language that facilitates cross-mapping among local terms and existing terminologies. ICNP conforms to current terminology standards and criteria, for example, ISO standards and HL7. The ICNP Alpha and Beta Versions documented the progress of concept validation and classification of nursing phenomena and interventions. The ICNP Beta 2 Version was a combinatorial terminology organized in two multi-axial structures representing nursing phenomena and nursing actions. The ICNP Version 1.0, launched in 2005, changed the relatively straight-forward multi-axial structure into a compositional terminology through the application of description logics using Web Ontology Language (OWL) within Protégé, an ontology development environment. ICNP Version 1.0 is also represented in a multiaxial model (7-Axis) for nurses to compose nursing diagnosis, intervention and outcome statements. Language translations and clinical information systems applications are required to make the ICNP Version 1.0 available to nurses at the point of healthcare delivery. ICNP data collected in healthcare environments provide standardized terminology for nursing that allows comparison of nursing practice across health care settings, specialties and countries; facilitate data-based clinical and management decision making; and contribute to the development of guidelines and standards for best practices and optimal outcomes for patients, families and communities.

    One of the main achievements of the IHD/IHP programs is the promotion and enhancement of hydrological data exchange within the global water community. World Catalogue of Very Large Floods, World Water Balance and Water Resources of the Earth are the great examples of some initial collaborative efforts and the FRIEND and Catalogue of Rivers for Southeast Asia and the Pacific are the more recent outcomes. Along with similar efforts by WMO, FAO, IGBP, CEOS and many other national and international institutes, the global hydrological monitoring and nowcast have made a considerable progress last decade and are about to put into practice. Such efforts include global streamflow alert system of U Maryland and GFAS-streamflow of ICHARM and U Yamanshi. Especially the recent achievements of GFAS-streamflow support the current efforts of IHP International Flood Initiative (IFI) and International Drought Initiatives (IDI) by global nowcasts and easily visible indicators in 20-km resolution.

    2015-01-01

    Purpose: Most clinically deployed strategies for respiratory motion management in lung radiotherapy (e.g., gating and tracking) use external markers that serve as surrogates for tumor motion. However, typical lung phantoms used to validate these strategies are based on a rigid exterior and a rigid or a deformable-interior. Such designs do not adequately represent respiration because the thoracic anatomy deforms internally as well as externally. In order to create a closer approximation of respiratory motion, the authors describe the construction and experimental testing of an externally as well as internally deformable, programmable lung phantom. Methods: The outer shell of a commercially available lung phantom (RS-1500, RSD, Inc.) was used. The shell consists of a chest cavity with a flexible anterior surface, and embedded vertebrae, rib-cage and sternum. A custom-made insert was designed using a piece of natural latex foam block. A motion platform was programmed with sinusoidal and ten patient-recorded lung tumor trajectories. The platform was used to drive a rigid foam “diaphragm” that compressed/decompressed the phantom interior. Experimental characterization comprised of determining the reproducibility and the external–internal correlation of external and internal marker trajectories extracted from kV x-ray fluoroscopy. Experiments were conducted to illustrate three example applications of the phantom—(i) validating the geometric accuracy of the VisionRT surface photogrammetry system; (ii) validating an image registration tool, NiftyReg; and (iii) quantifying the geometric error due to irregular motion in four-dimensional computed tomography (4DCT). Results: The phantom correctly reproduced sinusoidal and patient-derived motion, as well as realistic respiratory motion-related effects such as hysteresis. The reproducibility of marker trajectories over multiple runs for sinusoidal as well as patient traces, as characterized by fluoroscopy, was within 0

    Short-term effectiveness of the International Child Development Programme (ICDP) for parents in the general population has been studied. The aim of this paper was to investigate the longer term impact of the ICDP programme on parents looking for sustained changes 6–12 months after the programme. For this, a non-clinical caregiver group attending the ICDP programme (N = 79) and a non-attending comparison group (N = 62) completed questionnaires on parenting, psychosocial functioning, and child difficulties before, on completion and 6–12 months after the ICDP programme. Analyses compare changes in scores over time. The results revealed that the ICDP group showed significantly improved scores on parenting measures, less loneliness, and trends towards improved self-efficacy compared to the comparison group 6–12 months after programme completion. The ICDP group also reported that their children spent significantly less time on television and computer games and a trend towards fewer child difficulties. Key positive effects sustained over time but at a somewhat lower level, supporting community-wide implementation of ICDP as a general parenting programme. It is concluded that more intensive training with follow-up sessions should be considered to sustain and boost initial gains. PMID:25431603

    The long-term monitoring of basic hydrological parameters (temperature and salinity), collected as time series with adequate temporal resolution (i.e. with a sampling interval allowing the resolution of all important timescales) in key places of the Mediterranean Sea (straits and channels, zones of dense water formation, deep parts of the basins), constitute a priority in the context of global changes. This led CIESM (The Mediterranean Science Commission) to support, since 2002, the HYDROCHANGES programme (http//www.ciesm.org/marine/programs/hydrochanges.htm), a network of autonomous conductivity, temperature, and depth (CTD) sensors, deployed on mainly short and easily manageable subsurface moorings, within the core of a certain water mass. The HYDROCHANGES strategy is twofold and develops on different scales. To get information about long-term changes of hydrological characteristics, long time series are needed. But before these series are long enough they allow the detection of links between them at shorter timescales that may provide extremely valuable information about the functioning of the Mediterranean Sea. The aim of this paper is to present the history of the programme and the current set-up of the network (monitored sites, involved groups) as well as to provide for the first time an overview of all the time series collected under the HYDROCHANGES umbrella, discussing the results obtained thanks to the programme.

    Landscape morphology has an important control on the spatial and temporal organization of basin hydrologic response to climate forcing, affecting soil moisture redistribution as well as vegetation function. On the other hand, erosion, driven by hydrology and modulated by vegetation, produces landforms over geologic time scales that reflect characteristic signatures of the dominant land forming process. Responding to extreme climate events or anthropogenic disturbances of the land surface, infrequent but rapid forms of erosion (e.g., arroyo development, landsliding) can modify topography such that basin hydrology is significantly influenced. Despite significant advances in both hydrologic and geomorphic modeling over the past two decades, the dynamic interactions between basin hydrology, geomorphology and terrestrial ecology are not adequately captured in current model frameworks. In order to investigate hydrologic-geomorphic-ecologic interactions at the basin scale we present initial efforts in integrating the CHILD landscape evolution model (Tucker et al. 2001) with the tRIBS hydrology model (Ivanov et al. 2004), both developed in a common software environment. In this talk, we present preliminary results of the numerical modeling of the coupled evolution of basin hydro-geomorphic response and resulting landscape morphology in two sets of examples. First, we discuss the long-term evolution of both the hydrologic response and the resulting basin morphology from an initially uplifted plateau. In the second set of modeling experiments, we implement changes in climate and land-use to an existing topography and compare basin hydrologic response to the model results when landscape form is fixed (e.g. no coupling between hydrology and geomorphology). Model results stress the importance of internal basin dynamics, including runoff generation mechanisms and hydrologic states, in shaping hydrologic response as well as the importance of employing comprehensive

    Water in its different forms has always been a source of wonder, curiosity and practical concern for humans everywhere. Hydrology - An Introduction presents a coherent introduction to the fundamental principles of hydrology, based on the course that Wilfried Brutsaert has taught at Cornell University for the last thirty years. Hydrologic phenomena are dealt with at spatial and temporal scales at which they occur in nature. The physics and mathematics necessary to describe these phenomena are introduced and developed, and readers will require a working knowledge of calculus and basic fluid mechanics. The book will be invaluable as a textbook for entry-level courses in hydrology directed at advanced seniors and graduate students in physical science and engineering. In addition, the book will be more broadly of interest to professional scientists and engineers in hydrology, environmental science, meteorology, agronomy, geology, climatology, oceanology, glaciology and other earth sciences. Emphasis on fundamentals Clarification of the underlying physical processes Applications of fluid mechanics in the natural environment

    Organisations like the International Cartographic Association champion programmes that develop and deliver education and training to cartographers and geospatial scientists, globally. This can be in the form of traditional university and training college programmes, short courses for professional and technical members of mapping agencies and as outreach initiatives to transfer knowledge about the discipline and its contemporary practices. Through its international community, the ICA undertakes the transfer of knowledge about cartography and GI Science by publishing books and special editions of journals and running workshops. Colleagues from the ICA community conduct these workshops on a volunteer basis, generally with the support of the national member organisation of ICA or the national mapping body. For example, the ICA promotes the generation of extensive publications, generally through its Commissions and Working Groups. The publications include books, journals and the ICA Newsletter. Outreach activities are especially pertinent to up skill colleagues from developing countries. Specialist programmes can be offered for professional and 'everyday' map users (from adults to children). The ICA can assist with its current programmes, designed to embrace professional and non-professional cartographers alike. This paper will address how education and outreach programmes can be supported by international associations, by offering programmes independently, or in partnership with sister associations and national and regional organisations and societies. As well, the paper will address the need to deliver education and outreach programmes not to just the professional international community, but also to map users and citizen map publishers.

While the hydrological cycle is a circular closed environment, if we open up our perspectives to social sciences, we will demonstrate how, thanks to virtual water, it is today possible to elaborate how much water 'enters or leave' any water body under the form crop-export, in terms of " water used for the production of agri-food products'. This new 'hydro-political cycle' will be discussed at the light of different theoretical perspectives: food trade theories, hydrology, international water law, socio-economic metabolism, material flow analysis.

  17. Large-basin hydrological response to climate model outputs: uncertainty caused by internal atmospheric variability

    2015-06-01

    An approach is proposed to assess hydrological simulation uncertainty originating from internal atmospheric variability. The latter is one of three major factors contributing to uncertainty of simulated climate change projections (along with so-called "forcing" and "climate model" uncertainties). Importantly, the role of internal atmospheric variability is most visible over spatio-temporal scales of water management in large river basins. Internal atmospheric variability is represented by large ensemble simulations (45 members) with the ECHAM5 atmospheric general circulation model. Ensemble simulations are performed using identical prescribed lower boundary conditions (observed sea surface temperature, SST, and sea ice concentration, SIC, for 1979-2012) and constant external forcing parameters but different initial conditions of the atmosphere. The ensemble of bias-corrected ECHAM5 outputs and ensemble averaged ECHAM5 output are used as a distributed input for the ECOMAG and SWAP hydrological models. The corresponding ensembles of runoff hydrographs are calculated for two large rivers of the Arctic basin: the Lena and Northern Dvina rivers. A number of runoff statistics including the mean and the standard deviation of annual, monthly and daily runoff, as well as annual runoff trend, are assessed. Uncertainties of runoff statistics caused by internal atmospheric variability are estimated. It is found that uncertainty of the mean and the standard deviation of runoff has a significant seasonal dependence on the maximum during the periods of spring-summer snowmelt and summer-autumn rainfall floods. Noticeable nonlinearity of the hydrological models' results in the ensemble ECHAM5 output is found most strongly expressed for the Northern Dvina River basin. It is shown that the averaging over ensemble members effectively filters the stochastic term related to internal atmospheric variability. Simulated discharge trends are close to normally distributed around the ensemble

  20. Can international health programmes be sustained after the end of international funding: the case of eye care interventions in Ghana

    PubMed Central

    2014-01-01

    Background There is general agreement amongst major international policy makers that sustainability is a key component of health interventions in developing countries. However, there is little evidence on the factors enabling or constraining sustainability. Diffusion of innovation theory can help explain how the continuation of activities is related to the attributes of innovations. Innovations are characterised by five attributes: (i) relative advantage; (ii) compatibility; (iii) complexity; (iv) triability; and (v) observability. An eye care programme was selected as a case study. The programme was implemented in the Brong Ahafo region of Ghana and had been funded over a ten-year period by an international organisation. Methods Sustainability in the study was defined as the level of continuation of activities after the end of international funding. Measuring the continuation of activities involved checking whether each eye care activity continued (i.e. out-patient consultation, cataract surgery, outreach, school health, and statistics) or was interrupted after the end of Swiss Red Cross funding the 11 district hospitals where the programme was implemented. Results The results showed a relationship between the level of sustainability and the attributes of every activity. The activities with the lowest score for the attributes were less sustained. School health screening was the least sustained activity after the end of international funding. This activity also held the smallest score in terms of attributes: they were the most incompatible and most complex activities, as well as the least triable and observable activities, amongst the four district activities. In contrast, compared to the three other district activities, facility-based consultations were more likely to be routinised because they were perceived by the hospital managers as very compatible, and not complex. Conclusions Using diffusion of innovations theories can help predict the sustainability of

    2001-12-01

    The International Association of Hydrological Sciences(IAHS) is the oldest and foremost international nongovernmental organization which deals with hydrology and water resources. It was established in 1922 with the aim of bringing together hydrologists from all countries to promote the hydrological sciences. International meetings are held once every two years, first, in concert with the General Assembly of the International Union of Geodesy and Geophysics(IUGG)(which is held every four years), the parent body of IAHS, and then in the midterm between IUGG General Assemblies in IAHS Scientific Assemblies. In addition, IAHS organizes and co-sponsors conferences, symposia, workshops, and courses, primarily through the efforts of its nine International Commissions on Remote Sensing(ICRS), Surface Water, Groundwater, Continental Erosion, Snow and Ice, Water Quality, Water Resources Systems, Atmosphere-Soil-Vegetation Relations, and Tracers. IAHS offers memberships to individuals for no annual fee. IAHS maintains close collaboration with UNESCO, WMO, and IAEA through their respective hydrology and water resources programs. IAHS recently decided that although its scientific meetings have been successful, some new additional activities were merited. In addition to holding international meetings, the IAHS Bureau decided that IAHS should become more proactive by focusing on critical worldwide water problems and developing research programs to address these problems. Particularly, IAHS needs to address global water issues through direct involvement in policy oriented activities such as those of the World Water Council and World Water Forum 3 as well as many ongoing UN and ICSU science programs. IAHS plans to take strong leadership in such programs by demonstrating scientific solutions of problems of hydrologic uncertainty and resulting improvements for water management. In order to focus our scientific activities and make the scientific potentials practical, IAHS followed a

    Abstract Problem According to the International Health Regulations (IHR), countries need to strengthen core capacity for disease surveillance and response systems. Many countries are establishing or enhancing their field epidemiology training programmes (FETPs) to meet human resource needs but face challenges in sustainability and training quality. Indonesia is facing these challenges, which include limited resources for field training and limited coordination in a newly decentralized health system. Approach A national FETP workplan was developed based on an evaluation of the existing programme and projected human resource needs. A Ministry of Health Secretariat linking universities, national and international partners was established to oversee revision and implementation of the FETP. Local setting The FETP is integrated into the curriculum of Indonesian universities and field training is conducted in district and provincial health offices under the coordination of the universities and the FETP Secretariat. Relevant changes The FETP was included in the Ministry of Health workforce development strategy through governmental decree. Curricula have been enhanced and field placements strengthened to provide trainees with better learning experiences. To improve sustainability of the FETP, links were established with the Indonesian Epidemiologists’ Association, local governments and donors to cultivate future FETP champions and maintain funding. Courses, competitions and discussion forums were established for field supervisors and alumni. These changes have increased the geographic distribution of students, intersectoral and international participation and the quality of student performance. Lessons learnt The main lesson learnt is that linkages with universities, ministries and international agencies such as the World Health Organization are critical for building a sustainable high-quality programme. The most critical factors were development of trusting relationships

  6. Calibration of a Physically-Based Semi-Distributed Hydrologic Model: The Importance of Internal Justification

    NASA Astrophysics Data System (ADS)

    Tasdighi, A.; Arabi, M.

    2014-12-01

    Calibration of physically-based distributed hydrologic models has always been a challenging task and subject of controversy in the literature. This study is aimed to investigate how different physiographic characteristics of watersheds call for adaption of the methods used in order to have more robust and internally justifiable simulations. Haw Watershed (1300 sq. mi.) is located in the piedmont region of North Carolina draining into B. Everett Jordan Lake located in west of Raleigh. Major land covers in this watershed are forest (50%), urban/suburban (21%) and agriculture (25%) of which a large portion is pasture. Different hydrologic behaviors are observed in this watershed based on the land use composition and size of the sub-watersheds. Highly urbanized sub-watersheds show flashier hydrographs and near instantaneous hydrologic responses. This is also the case with smaller sub-watersheds with relatively lower percentage of urban areas. The Soil and Water Assessment Tool (SWAT) has been widely used in the literature for hydrologic simulation on daily basis using Soil Conservation Service Curve Number method (SCS CN). However, it has not been used as frequently using the sub-daily routines. In this regard there are a number of studies in the literature which have used coarse time scale (daily) precipitation with methods like SCS CN to calibrate SWAT for watersheds containing different types of land uses and soils reporting satisfying results at the outlet of the watershed. This is while for physically-based distributed models, the more important concern should be to check and analyze the internal processes leading to those results. In this study, the watershed is divided into several sub-watersheds to compare the performance of SCS CN and Green & Ampt (GA) methods on different land uses at different spatial scales. The results suggest better performance of GA compared to SCS CN for smaller and highly urbanized sub-watersheds although GA predominance is not very

    The first project of the World Climate Research Program is the International Satellite Cloud Climatology Project, (ISCCP) whose objective is the collection and analysis of satellite radiance data in order to infer the global distribution of cloud radiative properties and improve the modeling of cloud effects on climate. The operational component of ISCCP takes advantage of the global coverage provided by the current and planned international array of geostationary and polar-orbiting meteorological satellites in the 1980s. It will produce a five-year global radiance and cloud data set. The research component of ISCCP will coordinate studies to validate climatology, improve cloud analysis algorithms, improve cloud effects modelling, and investigate the role of clouds in the atmospheric radiation budget and hydrologic cycle.

    2014-12-01

    There are two mainstream curricula for international school students at the junior high level: the International Baccalaureate (IB) Middle Years Programme (MYP) and the Cambridge International General Certificate of Secondary Education (IGCSE). The former was developed in the mid-1990s and is currently being relaunched in a 21st-century approach. The latter programme of study was developed by University of Cambridge International Examinations in 1985 and has become popular in recent years among British domestic and international schools worldwide due to the clarity of its learning content. The prevailing uncertainty about which curriculum is best to prepare students for the IB Diploma Programme represents a challenge for international schools. The purpose of the current study is to develop a methodology through causal models which can explain the relationship between student performance in the IGCSE and the Diploma Programme with regard to mathematics and science. The data evaluated here consisted of external examination scores of students who attended a private international high school between the years 2005 and 2012. Two structural equation models were developed. The first model employed a maximum likelihood estimation, while the second model used a Bayesian estimation with a Markov Chain Monte Carlo method. Both models fit the data well. The evidence suggests that the IGCSE provides a good foundational preparation for the Diploma Programme in mathematics and science.

    Food composition data have extensively been used in the Choices International Programme: they formed the basis of both criteria development and nutrient intake modeling. Criteria were developed for key nutrients linked to non communicable diseases by an independent scientific committee. The criteria can be used for the logo assignment on food products, in order to stimulate producers to improve their products and to stimulate consumers to purchase these products. Insights in steps of development of the criteria for the Choices program illustrates the importance of food composition data in this process. Modeling studies with the criteria for the Dutch Choices program showed an improved nutrient intake profile if consumers would choose products fulfilling the criteria of the Dutch logo as part of their diets. The role and availability of food composition databases in the development of the criteria and the modeling studies is discussed. PMID:26433308

  13. Consistency of internal fluxes in a hydrological model running at multiple time steps

    2016-04-01

    Improving hydrological models remains a difficult task and many ways can be explored, among which one can find the improvement of spatial representation, the search for more robust parametrization, the better formulation of some processes or the modification of model structures by trial-and-error procedure. Several past works indicate that model parameters and structure can be dependent on the modelling time step, and there is thus some rationale in investigating how a model behaves across various modelling time steps, to find solutions for improvements. Here we analyse the impact of data time step on the consistency of the internal fluxes of a rainfall-runoff model run at various time steps, by using a large data set of 240 catchments. To this end, fine time step hydro-climatic information at sub-hourly resolution is used as input of a parsimonious rainfall-runoff model (GR) that is run at eight different model time steps (from 6 minutes to one day). The initial structure of the tested model (i.e. the baseline) corresponds to the daily model GR4J (Perrin et al., 2003), adapted to be run at variable sub-daily time steps. The modelled fluxes considered are interception, actual evapotranspiration and intercatchment groundwater flows. Observations of these fluxes are not available, but the comparison of modelled fluxes at multiple time steps gives additional information for model identification. The joint analysis of flow simulation performance and consistency of internal fluxes at different time steps provides guidance to the identification of the model components that should be improved. Our analysis indicates that the baseline model structure is to be modified at sub-daily time steps to warrant the consistency and realism of the modelled fluxes. For the baseline model improvement, particular attention is devoted to the interception model component, whose output flux showed the strongest sensitivity to modelling time step. The dependency of the optimal model

    The International Atomic Energy Agency (IAEA) has a mandate to assist member states in areas of human health and particularly in the use of radiation for diagnosis and treatment. Clinical audit is seen as an essential tool to assist in assuring the quality of radiation medicine, particularly in the instance of multidisciplinary audit of diagnostic radiology. Consequently, an external clinical audit programme has been developed by the IAEA to examine the structure and processes existent at a clinical site, with the basic objectives of: (1) improvement in the quality of patient care; (2) promotion of the effective use of resources; (3) enhancement of the provision and organisation of clinical services; (4) further professional education and training. These objectives apply in four general areas of service delivery, namely quality management and infrastructure, patient procedures, technical procedures and education, training and research. In the IAEA approach, the audit process is initiated by a request from the centre seeking the audit. A three-member team, comprising a radiologist, medical physicist and radiographer, subsequently undertakes a 5-d audit visit to the clinical site to perform the audit and write the formal audit report. Preparation for the audit visit is crucial and involves the local clinical centre completing a form, which provides the audit team with information on the clinical centre. While all main aspects of clinical structure and process are examined, particular attention is paid to radiation-related activities as described in the relevant documents such as the IAEA Basic Safety Standards, the Code of Practice for Dosimetry in Diagnostic Radiology and related equipment and quality assurance documentation. It should be stressed, however, that the clinical audit does not have any regulatory function. The main purpose of the IAEA approach to clinical audit is one of promoting quality improvement and learning. This paper describes the background to

    NASA Astrophysics Data System (ADS)

    Valentine, D. W.; Taylor, P.; Arctur, D. K.; Zaslavsky, I.

    2011-12-01

    The CUAHSI Hydrologic Information System (HIS) project is migrating core components of its service-oriented infrastructure to information models and service interfaces being standardized by the Open Geospatial Consortium (OGC), through coordination with the joint Hydrology Domain Working Group (HDWG) of the OGC and the World Meteorological Organization. The CUAHSI cyberinfrastructure for hydrologic observations will rely on OGC service standards including Web Map Service (WMS) for map portrayal, Web Feature Service (WFS) for delivery of geographic feature information, Catalog Services for the Web (CSW) for discovery in service catalogs, and Sensor Observation Service (SOS) for data delivery. These standards will be supplemented by additional services and corresponding standards, such as the Water Quality Exchange (WQX), which is presently in use at the USGS and US EPA for delivery of water quality and ex situ analytical data. One of the key standards being developed through the OGC process is Water Markup Language (WaterML) 2.0, which specifies standard encoding for the representation of in-situ hydrological observations. Implemented as an application schema of OGC Observations and Measurements (O&M) standard, WaterML 2.0 incorporates the semantics of the hydrologic information: location, procedure, and observations, focusing on encoding different types of hydrologic time series. In addition to developing this exchange standard, the HDWG conducts Interoperability Experiments (IE) to test WaterML 2.0 and OGC services to see they meet the requirements of the Hydrologic community. The Groundwater IE tested cross border exchange of water information between the US and Canada, and exercised, not only a prototype of WaterML 2.0, but existing standards GeoSciML and GroundwaterML. A Surface Water IE is testing 3 use cases focusing on cross-border exchange of surface water information, hydrologic forecasting, and automated monthly and yearly volume calculations from large

    International partnerships are a mechanism for supporting the academic development of occupational therapy and promoting cultural competence. This case study describes the factors that have helped to sustain a post-qualifying programme implemented by five higher education institutions in Denmark, the Netherlands, Sweden, Switzerland and the UK since 1999. Data collection methods were documentary analysis and the reflections of a purposive sample of six key informants. Cohort and outcome data, from 193 students from 31 countries who enrolled between 1999 and 2011, are reported. Each cohort comprises students from an average of eight countries to optimize inter-cultural dialogue. Four factors support sustainability. These are 1) supportive professional European networks; 2) timeliness and alignment with European higher education policy; 3) partnership structures and processes that emphasize joint decision making and accountability; and 4) the stimulus and satisfaction associated with internationalization. The main limitations are considering the OT-EuroMaster as an intrinsic case study and using opportunistic data collection that undermines the rigor and transferability of the findings. Future opportunities include doctoral networks, transnational research and sharing our curricula design with other Regions to spread the collaborative, capacity building endeavours more widely.

    The International Geosphere Biosphere Programme Data and Information System (IGBP-DIS), through the mapping expertise of the U.S. Geological Survey and the European Commission's Joint Research Centre, recently guided the completion of a 1-km resolution global land cover data set from advanced very high resolution radiometer (AVHRR) data. The 1-km resolution land cover product, 'DISCover,' was based on monthly normalized difference vegetation index composites from 1992 and 1993. The development of DISCover was coordinated by the IGBP-DIS Land Cover Working Group as part of the IGBP-DIS Focus 1 activity. DISCover is a 17-class land cover data set based on the scientific requirements of IGBP elements. The mapping used unsupervised classification and postclassification refinement using ancillary data. The development of this data set was motivated by the need for global land cover data with higher spatial resolution, improved temporal specificity, and known classification accuracy. The completed DISCover data set will soon be validated to determine the accuracy of the global classification.

    Nuclear power plants (NPPs) are increasingly faced with the challenge of qualifying procured equipment, sub-components, and systems that contain digital programmed electronics for use in safety-related applications. Referred to as a 'programmable electronic system' (PES), such equipment typically contains both complex logic that is vulnerable to systematic design faults, and low voltage electronics hardware that is subject to random faults. Procured PES products or components are often only commercial grade, yet can offer reliable cost effective alternatives to custom-designed or nuclear qualified equipment, provided they can be shown to meet the quality assurance, functional safety, environmental, and reliability requirements of a particular application. The process of confirming this is referred to as application-specific product qualification (ASPQ) and can be challenging and costly. This paper provides an overview of an approach that has been developed at Atomic Energy Canada Limited (AECL) and successfully applied to PES equipment intended for use in domestic Candu R 6 nuclear power plants and special purpose reactors at Chalk River Laboratories. The approach has evolved over the past decade and has recently been adapted to be consistent with, and take advantage of new standards that are applicable to nuclear safety-related I and C systems. Also discussed are how recognized third-party safety-certifications of PES equipment to International Electrotechnical Commission (IEC) standards, and the assessment methods employed, may be used to reduce ASPQ effort.

    "Panta Rhei - Everything Flows" is the new scientific decade, 2013-2022, of the International Association of Hydrological Sciences (IAHS). It is dedicated to understanding issues linked with the interactions between hydrology and society in the context of change. The purpose of Panta Rhei is to reach an improved interpretation of the processes governing the water cycle in the Anthropocene, an improved prediction of such systems, and where possible to provide input for policy and practice, aimed at water security, human wellbeing and development. This talk discusses the research initiative, explores the possibility of research innovations offered by the research initiative and how water footprint assessment is a valuable tool to understand and assess human impacts on the water cycle in the Anthropocene.

  8. External threats and internal management: the hydrologic regulation of the Everglades, Florida, USA

    NASA Astrophysics Data System (ADS)

    Kushlan, James A.

    1987-01-01

    The ecological character of seasonal marshes is determined in large part by the pattern of water level fluctuation. As a result, the ecological health of a wetland reserve can be controlled by hydrologic regulation external to its boundaries. As an example, the Everglades marsh of Everglades National Park in Florida, USA, has been severely effected by management of the inflow of surface water. The Everglades occupies most of the interior of southern Florida, but only the lower 6% of the original marsh is contained in Everglades National Park. Shallow surface water reservoirs north of the park enclose 3600 km2 of Everglades. Their levee system confines surface water flow into the park to several structures. Historically this water flowed across the entire core of the natural drainage. Flows into the park have been on a congressionally mandated schedule of minimum deliveries that is supplemented by additional water released into the park in amounts determined solely by upstream water management needs. My research, aimed at evaluating the effects of water conditions, has shown that this regulatory system has adversely affected reproductive success, community structure, and population sizes of sensitive species whose population stability is tied to natural water level fluctuations. These adverse effects were caused by water levels that for over a decade have been maintained at unseasonably high levels. Mathematically deterministic models of water level effects can provide management options based on biologial criteria. Park managers must incorporate understanding gained from such models into internal management decisions. Modifications of water control structures and alternative policies for managing the distribution and amount of surface water flow into the park appear attainable, can improve biological conditions in the park, and need not be adverse to neighboring external interests. Thus far biological changes are severe, and to a large extent irreversible

    2006-08-02

    As part of the ongoing international DECOVALEX project, four research teams used five different models to simulate coupled thermal, hydrological, and mechanical (THM) processes near waste emplacement drifts of geological nuclear waste repositories. The simulations were conducted for two generic repository types, one with open and the other with back-filled repository drifts, under higher and lower postclosure temperatures, respectively. In the completed first model inception phase of the project, a good agreement was achieved between the research teams in calculating THM responses for both repository types, although some disagreement in hydrological responses is currently being resolved. In particular, good agreement in the basic thermal-mechanical responses was achieved for both repository types, even though some teams used relatively simplified thermal-elastic heat-conduction models that neglected complex near-field thermal-hydrological processes. The good agreement between the complex and simplified process models indicates that the basic thermal-mechanical responses can be predicted with a relatively high confidence level.

    2011-01-01

    Scores of modeling studies have shown that increasing greenhouse gases in the atmosphere impact the global hydrologic cycle; however, disagreements on regional scales are large, and thus the simulated trends of such impacts, even for regions as large as the tropics, remain uncertain. The present investigation attempts to examine such trends in the observations using satellite data products comprising Global Precipitation Climatology Project precipitation and International Satellite Cloud Climatology Project cloud and radiation. Specifically, evolving trends of the tropical hydrological cycle over the last 20-30 years were identified and analyzed. The results show (1) intensification of tropical precipitation in the rising regions of the Walker and Hadley circulations and weakening over the sinking regions of the associated overturning circulation; (2) poleward shift of the subtropical dry zones (up to 2deg/decade in June-July-August (JJA) in the Northern Hemisphere and 0.3-0.7deg/decade in June-July-August and September-October-November in the Southern Hemisphere) consistent with an overall broadening of the Hadley circulation; and (3) significant poleward migration (0.9-1.7deg/decade) of cloud boundaries of Hadley cell and plausible narrowing of the high cloudiness in the Intertropical Convergence Zone region in some seasons. These results support findings of some of the previous studies that showed strengthening of the tropical hydrological cycle and expansion of the Hadley cell that are potentially related to the recent global warming trends.

    The International Satellite Land Surface Climatology Project Initiative 2 (ISLSCP-2) data set provides the data needed to characterize the surface water budget across much of the globe in terms of energy availability (net radiation) and water availability (precipitation) controls. The data, on average, are shown to be consistent with Budyko s decades-old framework, thereby demonstrating the continuing relevance of Budyko s semiempirical relationships. This consistency, however, appears only when a small subset of the data with hydrologically suspicious behavior is removed from the analysis. In general, the precipitation, net radiation, and runoff data also appear consistent in their interannual variability and in the phasing of their seasonal cycles.

  15. Images, femininity and cancer: an analysis of an international patient education programme.

    Phillips, Catherine

    2009-01-01

    This article is an analysis of a cancer patient education programme run by cosmetic companies. I focus on an analysis of imagery, arguing that there are particular discursive elements that the cosmetic companies use in order to make productive the relationship between femininity and cancer. I contextualize this education programme by presenting the controversies regarding cosmetics as they relate to the growth of breast tumours. In doing so, I conclude that conversations and questions about a link between chemicals and cancer are subverted by both ;horror' narratives of cancer and the provocative use of standards of beauty. Such discursive dominance in patient education programmes makes it difficult to engage in a more public understanding of cancer growth as affected by cosmetic chemicals. PMID:19103716

    Advancements in hydrology proceeded slowly until the late 1800's when new ventures created a surge of interest and accomplishment. Progress waned again until the middle 20th century when an International Hydrological Decade was conceived, eventually receiving wide multinational support from governmental agencies and nongovernmental institutions. Organized by UNESCO, the Decade program was launched January 1, 1965. Participation included 107 nations, six United Nations agencies, and more than a dozen international scientific organizations. The initial program emphasized scientific research, and international cooperation; the second half of the Decade, emphasized technical assistance and technology transfer, largerly through education, training and demonstration. The success of the Decade led to the establishment of the International Hydrological Program, again under the aegis of UNESCO, to continue the work of the Decade indefinitely. The five major program activities, now involving about 90 countries and several international organizations, include: the scientific program, the promotion of education and training, the enhancement of information exchange, support of technical assistance, and the enlargement of regional cooperation. A significant amount of activity related to hydrological data networks and forecasting is carried on in an Operational Hydrology Programme by the WMO, chiefly through its Commission for Hydrology. Other international governmental organizations with a strong interest in water include the UN, the UN Development Programme, the FAO, the WHO, the International Atomic Energy Agency, the UN Environment Programme, the International Standardization Organization, and developmental institutions such as the World Bank. The specialized interests of researchers outside of the governmental structure, are met through association in various scientific and technical organizations which are world wide in scope and membership.

    In northern peatlands the thawing of permafrost by increasing the active layer depth and in turn change the hydrology may lead to feedbacks in the climate system through changes in the biogeochemistry of carbon. However, it is extremely difficult to determine the temporal-spatial dynamics of the permafrost-hydrological dynamics through empirical studies. We are examining this association on the Stordalen peatland complex in subarctic Sweden by analyzing a digital elevation model (DEM) derived from high resolution LIDAR-data and the calculation of a topographical wetness index (TWI). The DEM is tested with spatial resolutions of 0.5 and 1 m and the derived TWI [ln(a/tan b] (where a is the area upslope of the contributing area with slope b) is evaluated against two seasons of continuous water level measurements from 35 sites distributed through the peatland. The differences in spatial patterns reveal the resolution required to develop the technique to be useful for estimate variations in vegetation communities and carbon balance studies.

    When considering groundwater research focused on sustainable water supply in a developing region such as western Africa, questions that need to be addressed range from long-term variation in precipitation, to geochemical alteration of natural and anthropogenic contaminants, to development of management strategies that are consistent not only with technology but also with social and religious customs. While some may view these projects as 'service', these types of projects provide fertile ground for new technical and policy advances in the study of groundwater resources, with results that may provide substantial new insights to technological and policy issues in the United States. Research questions that might be addressed include impact of long-term uncertainties in climate, integration of data time-series of variable frequency and quality, measure of the value of a groundwater resource, integration of technical and social constraints on management strategies, and integration of multiple views of water as a resource. In addition, these types of projects provide opportunities for active collaboration with colleagues from other countries who view research in hydrology quite differently than do many of our colleagues in the United States. It is therefore argued that there is a demanding, challenging future for advances in the hydrologic sciences focused on sustainability issues in regions of the world for which groundwater is a critical resource limiting development.

    Educating the next generation of scientists requires new educational methods and unconventional approaches to facilitate the interdisciplinary scholarship required to cope with fast-paced developments in the geosciences. We believe incorporation of field training with active research missions is an effective educational model. By participating in active research and open science dialogue, students are exposed to real-world examples of the principles and processes of complex systems in a manner that allows them to develop a deeper understanding of the subject. We find students are highly motivated by the knowledge that data they collect will advance the research mission; such an environment stokes their passions and imaginations and allows the students to explore the roots of their interest in geoscience. In this context, a two-week educational field course on hydrologic processes and measurements was integrated with ongoing research in Chile to understand the effect of soil shrinkage and swelling properties on watershed hydrologic response. Students witnessed the iterative process of field-experiment design and became part of science in the making. They experienced the complexity of field work and developed problem-solving skills through the myriad of challenges presented in the acquisition of field data in a remote area. All of these factors contributed to an atmosphere of creativity that led to an outstanding research and educational experience. We find the coupling of field training with active research to be extremely rewarding, and time- and cost-effective education in this fast-paced and cost-cautious age.

    The precipitation in the Danube upper and middle basin is the main indicator for the Danube discharge at the entry in the lower basin. Along with precipitation, from the category of internal factors, in the first stage, we tried to find other predictors from the fields of temperature, pressure and geopotential. In the second phase, we considered external factors, taking into account the indices of solar/geomagnetic activity, represented by Wolf numbers, 10.7cm solar flux/aa geomagnetic index. In the Danube upper and middle basin, were considered fields of precipitation (PP), and temperatures (T) at 15 meteorological stations. The large-scale atmospheric circulation was quantified by Greenland-Balkan-Oscillation index (GBOI), North Atlantic Oscillation index and by blocking indices. The hydrological state in the Danube lower basin was represented by the discharge at the Orsova station. To estimate the discharge response in the Danube lower basin to various factors, developments in EOFs, cross correlations, power spectra, filters, composite maps were achieved. For the atmospheric variables, taken simultaneously, the most significant results (confidence level of 95%) are related to the predictors, considering the difference between standardized temperatures and precipitation (TPP), except for winter season, when the best predictors are PC1 of precipitation field and GBOI. In order to see the predictive hydrological response to the considered predictors, the correlative analyses with some lags were achieved. The significant results, were obtained for the winter/spring variables (PC1-precipitation and TPP), which can be considered good predictors for spring/summer discharge in the Danube lower basin. The hydrological response to the solar/ geomagnetic activity is given with a delay of two and three years. Due to the important signal of GBOI in the Danube basin precipitation in winter (correlation coefficient of 0.83), a stochastic modeling was performed between GBOI and

  15. A national medical education needs' assessment of interns and the development of an intern education and training programme.

    PubMed

    Hannon, F B

    2000-04-01

    A needs' assessment of interns was undertaken using a self-completion questionnaire and a semistructured interview. The questionnaire explored to what degree graduates had been helped to acquire a range of competencies and professional characteristics. In the interviews graduates discussed their self-perceived learning needs, their educational and training experiences and made suggestions. A 25% random sample of 1996 graduate doctors was selected from the five medical schools in Ireland (n=95). The overall response rate was 88% (n=84). The software package SPSS was utilized to carry out descriptive statistics on the questionnaire data while the interview data were analysed qualitatively. Of the responders, 91% reported that they were not prepared for all the skills needed as an intern. History taking and clinical examination were considered well covered at the undergraduate level but little training was received in a range of professional competencies and personal characteristics. Formal education and training during the intern year was found to be poor. However, some skills and characteristics improved during the year as a result of work experience. In the interviews the graduates explored educational issues. They considered an improved clinical experience throughout the undergraduate years to be at the heart of curriculum development but stressed that, in order to succeed, it would have to be accompanied by leadership within the healthcare system and efforts to improve the learning environment.

  16. Hydrological, morphometrical, and biological characteristics of the connecting rivers of the International Great Lakes: a review

    Edwards, Clayton J.; Hudson, Patrick L.; Duffy, Walter G.; Nepszy, Stephen J.; McNabb, Clarence D.; Haas, Robert C.; Liston, Charles R.; Manny, Bruce; Busch, Wolf-Dieter N.

    1989-01-01

    The connecting channels of the Great Lakes are large rivers (1, 200-9, 900 m3 • s-1) with limited tributary drainage systems and relatively stable hydrology (about 2:1 ration of maximum to minimum flow). The rivers, from headwaters to outlet, are the St. Marys, St. Clair, Detroit, Niagara, and St. Lawrence. They share several characteristics with certain other large rivers: the fish stocks that historically congregated for spawning or feeding have been overfished, extensive channel modification have been made, and they have been used as a repository for domestic and industrial wastes and for hydroelectric energy generation. Levels of phosphorus, chlorophyll a, and particulate organic matter increase 3- to 5-fold from the St. Marys River to the St. Lawrence River. Biological communities dependent on nutrients in the water column, such as phytoplankton, periphyton, and zooplankton similarly increase progressively downstream through the system. The standing crop of emergent macrophytes is similar in all of the rivers, reflecting the relatively large nutrient pools in the sediments and atmosphere. Consequently, emergent macrophytes are an important source of organic matter (67% of total primary production) in the nutrient poor waters of the St. Marys River, whereas phytoplankton production dominates (76%) in the enriched St. Lawrence River. Submersed and emergent macrophytes and the associated periphyton are major producers of organic matter in the connecting channels. Another major source of organic matter (measured as ash free dry weight, AFDW) in the Detroit River is sewage, introduced at a rate of 26, 000 t per year. The production of benthos ranges from a low 5.4 g AFDW•m-2 in the Detroit River to a high of 15.5 g AFDW•m-2 in the St. Marys River. The rivers lack the organic transport from riparian sources upstream but receive large amounts of high quality phytoplankton and zooplankton from the Great Lakes.

  17. Enhancing our Understanding of the Arctic Atmospheric Hydrological Cycle using Observations from an International Arctic Water Vapor Isotope Network

    2014-12-01

    Due to the role of water vapor and clouds in positive feedback mechanisms, water vapor is a key player in the future of Arctic climate. Ecosystems and human societies are vulnerable to climate change through even minor changes in precipitation patterns, including the occurrence of extreme events. It is therefore essential to monitor, understand and model correctly the mechanisms of transport of moisture, at the regional scale. Water isotopes - the relative abundance of heavy and light water in the atmosphere - hold the key to understanding the physical processes influencing future Arctic climate. Water isotope observations in the atmosphere are a modern analog to the Rosetta Stone for understanding the processes involved in evaporation, moisture transport, cloud formation and to track moisture origin. Indeed, technological progress now allows continuous, in situ or remote sensing monitoring of water isotopic composition. In parallel, a growing number of atmospheric circulation models are equipped with the explicit modeling of water stable isotopes, allowing evaluation at the process scale. We present here data obtained through national or bi-national initiatives from stations onboard an icebreaker and land based stations in Greenland, Iceland, Svalbard, and Siberia - together forming an emerging international Arctic water vapor isotope network. Using water tagging and back trajectories we show water vapor of Arctic origin to have a high d-excess fingerprint. This show the potential of using water vapor isotopes as tracer for changes in the Arctic hydrological cycle. Using the network of monitoring stations we quantify using the isotopes advection of air masses and the key processes affecting the water vapor en-route between stations. We have successfully used the obtained atmospheric water vapor isotope observations to benchmark isotope-enabled general circulation models. This comparison allows us to address key processes of the atmospheric hydrological cycle for

  6. SU-C-BRF-05: Design and Geometric Validation of An Externally and Internally Deformable, Programmable Lung Motion Phantom

    SciTech Connect

    Cheung, Y; Sawant, A

    2014-06-15

    Purpose: Most clinically-deployed strategies for respiratory motion management in lung radiotherapy (e.g., gating, tracking) use external markers that serve as surrogates for tumor motion. However, typical lung phantoms used to validate these strategies are rigid-exterior+rigid-interior or rigid-exterior+deformable-interior. Neither class adequately represents the human anatomy, which is deformable internally as well as externally. We describe the construction and experimental validation of a more realistic, externally- and internally-deformable, programmable lung phantom. Methods: The outer shell of a commercially-available lung phantom (RS- 1500, RSD Inc.) was used. The shell consists of a chest cavity with a flexible anterior surface, and embedded vertebrae, rib-cage and sternum. A 3-axis platform was programmed with sinusoidal and six patient-recorded lung tumor trajectories. The platform was used to drive a rigid foam ‘diaphragm’ that compressed/decompressed the phantom interior. Experimental characterization comprised of mapping the superior-inferior (SI) and anterior-posterior (AP) trajectories of external and internal radioopaque markers with kV x-ray fluoroscopy and correlating these with optical surface monitoring using the in-room VisionRT system. Results: The phantom correctly reproduced the programmed motion as well as realistic effects such as hysteresis. The reproducibility of marker trajectories over multiple runs for sinusoidal as well as patient traces, as characterized by fluoroscopy, was within 0.4 mm RMS error for internal as well as external markers. The motion trajectories of internal and external markers as measured by fluoroscopy were found to be highly correlated (R=0.97). Furthermore, motion trajectories of arbitrary points on the deforming phantom surface, as recorded by the VisionRT system also showed a high correlation with respect to the fluoroscopically-measured trajectories of internal markers (R=0.92). Conclusion: We have

    The 4th WCRP International Conference on Reanalyses provided an opportunity for the international community to review and discuss the observational and modelling research, as well as process studies and uncertainties associated with reanalysis of the Earth System and its components. Characterizing the uncertainty and quality of reanalyses is a task that reaches far beyond the international community of producers, and into the interdisciplinary research community, especially those using reanalysis products in their research and applications. Reanalyses have progressed greatly even in the last 5 years, and newer ideas, projects and data are coming forward. While reanalysis has typically been carried out for the individual domains of atmosphere, ocean and land, it is now moving towards coupling using Earth system models. Observations are being reprocessed and they are providing improved quality for use in reanalysis. New applications are being investigated, and the need for climate reanalyses is as strong as ever. At the heart of it all, new investigators are exploring the possibilities for reanalysis, and developing new ideas in research and applications. Given the many centres creating reanalyses products (e.g. ocean, land and cryosphere research centres as well as NWP and atmospheric centers), and the development of new ideas (e.g. families of reanalyses), the total number of reanalyses is increasing greatly, with new and innovative diagnostics and output data. The need for reanalysis data is growing steadily, and likewise, the need for open discussion and comment on the data. The 4th Conference was convened to provide a forum for constructive discussion on the objectives, strengths and weaknesses of reanalyses, indicating potential development paths for the future.

    Belarus has inherited a significant space research potential created back in the Soviet era. It is one of the countries in the world capable of research, engineering and production across a wide range of space technologies, such as remote sensing systems, satellite telecommunication systems and positioning systems etc. Despite these strengths, the participation of Belarusian space organizations in the UN space activity and International research programs is very low. Belarusian State University (BSU) is the leading research and high school education organization of Belarus in several fields of research and development. It was deeply involved into various space research projects, including Soviet Lunar Program, Space Station “Mir”, Space Shuttle “Buran”. From 2004, when the national space programs were restarted, branches of BSU like Institute of Physics and Aerospace Technologies (IPAT), Center for aerospace education, Research laboratory of applied space technologies are leading the research and development works in the field of space communication systems, Earth observation tools and technologies, electronic and optic sensors, etc. The mail fields of activity are: • Hard and software development for small satellites and university satellites in particular. • Development of sensor satellite systems. • Small satellite research experiments (biological and medical in particular). • Earth, airplane and satellite remote monitoring systems including hard and software. • Early warning ecological and industrial Systems. • Geographic information systems of several natural and industrial areas. • Climate change investigation. We have partners from several universities and research institutes from Russian Federation, Ukraine, Kazakhstan and Germany etc. We have a ground station to receive satellite data in RF L and X bands and are very interested to be incorporated into international remote monitoring network.

  9. Developing skills for youth in the 21st century: The role of elite International Baccalaureate Diploma Programme schools in China

    NASA Astrophysics Data System (ADS)

    Wright, Ewan; Lee, Moosung

    2014-04-01

    There is a growing body of research suggesting that schools need to respond to changing social and economic dynamics by prioritising "21st-century skills". Proponents of this view, who have been termed "the 21st century skills movement", have called for greater emphasis on cognitive and non-cognitive skills development, alongside the learning of subject content and technical skills. This paper explores the potential of International Baccalaureate Diploma Programme (IBDP) schools to respond to this mandate in China, one of the fastest-growing markets for International Baccalaureate® (IB) schools globally. The authors' research team undertook a multi-site case study of five elite IBDP schools in China. Their findings revealed confidence among interviewees that the IB educational philosophy was conducive to 21st-century skills development, especially through the provision of the three IBDP "Core Requirements", which are Creativity, Action, Service (CAS), Extended Essay (EE) and Theory of Knowledge (TOK). Despite this confidence, concerns remain about the implementation of the IB educational philosophy in the context of IBDP schools in China.

    1986-12-01

    The US Department of Energy (DOE) is participating in the international hydrologic code intercomparison (HYDROCOIN) project organized by the Swedish Nuclear Power Inspectorate (SKI) for the purpose of improving our knowledge about the influence of various strategies for ground-water flow modeling for the safety assessment of final repositories for nuclear waste. The HYDROCOIN project consists of three levels of effort: Level One is concerned with verifying the numerical accuracy of codes, Level Two is involved with validation of models using field experiments, and Level Three is concerned with sensitivity and uncertainty analysis. The need for the HYDROCOIN project emerged from an earlier international study for the intercomparison of computer codes for radionuclide transport (INTRACOIN). The HYDROCOIN project began in May 1984 with a group of fourteen organizations from eleven countries participating; currently twenty organizations are involved. Five teams from DOE's Office of Civilian Radioactive Waste Management (OCRWM) are participating in the HYDROCOIN project, and this document presents the results of a review of this participation and an analysis of the benefits of OCRWM participation in the first 2 years (i.e., through May 1986) of the 3-year HYDROCOIN project. Efforts on the seven Level One cases are nearly complete. Level Two problems have been formulated and are in final draft form, and Level Three problems have been identified and are in first draft form. This report details the motivation, need, and benefits from HYDROCOIN through a chronological synopsis of the project's progress to date, brief description and intercomparison of preliminary Level One results prepared by OCRWM participants, and discussion of OCRWM contributions and plans for HYDROCOIN Level Two and Three efforts.

    Approaches to expand malaria control interventions in areas of active conflict are urgently needed. Despite international agreement regarding the imperative to control malaria in eastern Burma, there are currently no large-scale international malaria programmes operating in areas of active conflict. A local ethnic health department demonstrated that village health workers are capable of implementing malaria control interventions among internally displaced persons (IDPs). This paper describes how these internally displaced villagers facilitated rapid expansion of the programme. Clinic health workers received training in malaria diagnosis and treatment, vector control and education at training sites along the border. After returning to programme areas inside Burma, they trained villagers to perform an increasingly comprehensive set of interventions. This iterative training strategy to increase human resources for health permitted the programme to expand from 3000 IDPs in 2003 to nearly 40,000 in 2008. It was concluded that IDPs are capable of delivering essential malaria control interventions in areas of active conflict in eastern Burma. In addition, health workers in this area have the capacity to train community members to take on implementation of such interventions. This iterative strategy may provide a model to improve access to care in this population and in other conflict settings. PMID:19384681

    Two meeetings gave rise to this special issue on numerical relativity: the workshop 'Numerical relativity' at the Banff International Research Station on 16 21 April 2005 and the conference 'New directions in numerical relativity' which was held at Southampton University on the 18 and 19 August 2005 as a satellite meeting of the Newton Institute Programme 'Global problems in mathematical relativity'. This edition contains contributions drawn from these two meetings. Looking back, 2005 will be remembered as the year in which key advances were made on a number of fronts which allowed significant progress in the binary black hole merger problem: at the Banff meeting, Frans Pretorius announced the first multi-orbit simulations, using a generalization of harmonic coordinates in which Friedrich's gauge source functions have been promoted to dynamical variables. Then, at the 'Numerical Relativity 2005' meeting held on 2 4 November 2005 at NASA Goddard, the NASA Goddard and Texas/Brownsville groups independently (in back-to-back talks!) announced multi-orbit simulations with waveforms using the Baumgarte Shapiro Shibata Nakamura 3+1 formulation with improved hyperbolic lapse and shift drivers, and representing the black holes as wormholes ('punctures') moving through the grid. These highlights were made possible by previous progress. Particularly important is the implementation of adaptive mesh refinement in general relativity in two and three dimensions, which not only allows for improved accuracy, but reduces the amount of time taken by 3D simulations, thus allowing systematic testing and improvement of 3D codes. In addition, the community is now much more aware of the importance of well-posedness of the continuum problem and the stability of the numerical methods, and some formal investigations of these matters have caused practical improvements. The same applies for the role of gauge choices and boundary conditions. Beyond the binary black hole problem, more

    The Swedish Regional Climate Modelling Programme, SWECLIM, was a 6.5-year national research network for regional climate modeling, regional climate change projections and hydrological impact assessment and information to a wide range of stakeholders. Most of the program activities focussed on the regional climate system of Northern Europe. This led to the establishment of an advanced, coupled atmosphere-ocean-hydrology regional climate model system, a suite of regional climate change projections and progress on relevant data and process studies. These were, in turn, used for information and educational purposes, as a starting point for impact analyses on different societal sectors and provided contributions also to international climate research.

    Internal loading is a critical component of the phosphorus (P) budget of aquatic systems, and can control the trophic conditions. While diffusion is generally considered the dominant process controlling internal P load to the water column, advection due to water table fluctuations resulting from episodic flooding and drying cycles can be a significant component of the P budget of depressional wetlands. Within the drainage basin of Lake Okeechobee, Florida, P is exported annually to the lake from impacted isolated wetlands located on beef farming facilities via ditches and canals. The objective of this study was to evaluate the role of diffusive and advective fluxes in relation to the total P loads entering and exiting one of these isolated wetlands. Diffusive fluxes were calculated from depth-variable pore water concentrations measured using multilevel samplers and pore water equilibrators. Advective fluxes were estimated based on groundwater fluctuations calculated within a hydrologic-budget framework. Results from an eleven-month monitoring period (May 2005-March 2006) indicated that the diffusive flux of soluble reactive P (SRP) was 0.42 ± 0.24 mg m-2 d-1 and occurred for 230 days out of 335. In comparison, the advective flux occurred over a shorter duration of just 21 days, yet generated a greater flux controlled by the concentrations of shallow pore water and the velocity of the ground water moving upwards into the wetland water column. The highest advective flux of SRP was estimated at 27.4 mg m-2 d-1. Based on these fluxes the corresponding P load to the wetland via internal modes was estimated at 5.2 kg and 0.93 kg from diffusion and advection respectively, representing a significant fraction of the total P load entering the wetland water column. Plant colonization during dry periods in P enriched soils is also a significant mechanism for P release from the soil at the time of flooding, however, this component to the wetland P budget was not evaluated as

  1. Hydrology as a policy-relevant science

    2004-11-01

    Water is now a global political agenda and water science is part of it. The United Nations Millennium Development Goals (MDGs) in 2000, the World Summit on Sustainable Development in 2002, the 3rd World Water Forum and Ministerial Conference in Kyoto in 2003 and the G8 Summit in Evian in 2003 were all concerned about urgent global water issues and call for international scientific research collaboration. Hydrology is responding to such political commitments with various scientific initiatives that include the International Association of Hydrological Sciences (IAHS) Predictions in Ungauged Basins (PUB), the Global Energy and Water Circulation Experiments (GEWEX) Coordinated Enhanced Observation Period (CEOP), and the Global Water Systems Project (GWSP). These initiatives will play key roles in the implementation of the new intergovernmental project, Global Earth Observing System of Systems, under preparation by Global Observation Summits from 2003 to 2005. In order to achieve the MDGs, hydrological science has to play a major role supporting policy makers by overcoming methodological obstacles and providing the necessary information. This paper emphasizes that: the availability of ground measurements is a limiting factor that prevents the full use of scientific knowledge; hydrology has to integrate and downscale the various global information into local-scale information useful for river basin management; as the availability of professional personnel is in critical short supply, in addition to funds needed, to achieve the MDGs any scientific research should always accompany capacity-building programmes to close the science divide between developed and developing nations.

    2008-12-01

    Before the International Polar Year, in Portugal polar research was conducted by a very small group of scientists integrated in foreign projects or research institutions. Portugal was not member of the Scientific Committee for Antarctic Research (SCAR), the European Polar Board (EPB), neither a subscriber of the Antarctic Treaty. In 2004 Portuguese Polar researchers considered the IPY as an opportunity to change this situation and organized the national Committee for the IPY. The objectives were ambitious: to answer the aforementioned issues in defining and proposing a National Polar Programme. In late 2008, close to the end of the IPY, the objectives were attained, except the Antarctic Treaty signature that is, however, in an advanced stage, having been approved by consensus at the National Parliament in early 2007. Portugal joined SCAR in July 2006, the EPB in 2007 and a set of 5 Antarctic research projects forming the roots of the National Polar Programme (ProPolar) have been approved by the Foundation for Science and Technology (FCT-MCTES). Scientifically, the IPY can already be considered a major success in Portugal with an improvement in polar scientific research, in the number of scientists performing field work in the Antarctic, organizing polar science meetings and producing an expected increase in the number of polar science peer- reviewed papers. The Portuguese IPY scientific activities were accompanied by a major education and outreach project funded by the Agencia Ciência Viva (MCTES): LATITUDE60! Education for the Planet in the IPY. This project lead by the universities of Algarve, Lisbon and by the Portuguese Association of Geography Teachers is heavily interdisciplinary, programmed for all ages, from kindergarten to adults, and hoped to bring together scientists and society. LATITUDE60! was a major success and focussed on showing the importance of the polar regions for Earth's environment, emphasising on the implications of polar change for

  3. Large Sample Hydrology : Building an international sample of watersheds to improve consistency and robustness of model evaluation

    2015-04-01

    This poster introduces the aims of the Large Sample Hydrology working group (LSH-WG) of the new IAHS Panta Rhei decade (2013-2022). The aim of the LSH-WG is to promote large sample hydrology, as discussed by Gupta et al. (2014) and to invite the community to collaborate on building and sharing a comprehensive and representative world-wide sample of watershed datasets. By doing so, LSH will allow the community to work towards 'hydrological consistency' (Martinez and Gupta, 2011) as a basis for hydrologic model development and evaluation, thereby increasing robustness of the model evaluation process. Classical model evaluation metrics based on 'robust statistics' are needed, but clearly not sufficient: multi-criteria assessments based on multiple hydrological signatures can help to better characterize hydrological functioning. Further, large-sample data sets can greatly facilitate: (i) improved understanding through rigorous testing and comparison of competing model hypothesis and structures, (ii) improved robustness of generalizations through statistical analyses that minimize the influence of outliers and case-specific studies, (iii) classification, regionalization and model transfer across a broad diversity of hydrometeorological contexts, and (iv) estimation of predictive uncertainties at a location and across locations (Mathevet et al., 2006; Andréassian et al., 2009; Gupta et al., 2014) References Andréassian, V., Perrin, C., Berthet, L., Le Moine, N., Lerat, J., Loumagne, C., Oudin, L., Mathevet, T., Ramos, M.

    Through its Support To Science Element (STSE) Programme, the European Space Agency (ESA) is currently sponsoring the North Hydrology project. The overall goal of North Hydrology is to support the international efforts coordinated by the Climate and Cryosphere (CliC) project of the World Climate Research Programme (WCRP) to exploit the use of Earth Observation (EO) technology, models and in situ data to improve the characterization of river and lake ice processes and their contribution to the Northern Hydrology system. To attain this goal, the North Hydrology project is developing a portfolio of new multi-mission geo-information products, maximizing the use of ESA satellite data, to respond to the scientific requirements of the CliC community and the operational requirements of the weather and climate operational agencies, and the requirements of the operational user community to better characterize river-ice (and glacier temporary lakes) dynamics in flood forecasting models at the basin scale. This talk will provide an overview of the North Hydrology project, the EO-based products it is generating (e.g. lake and river ice, land water surface temperature, ice flow dynamics and mass balance of outlet glaciers), the atmospheric and hydrological models it is using, and the EO data integration/assimilation experiments it is conducting.

    The International Committee of the Red Cross (ICRC) works in fragile States and in armed conflict zones. Some of them are affected by the HIV pandemic. Within the framework of its social responsibility programme concerning HIV affecting its staff members, the organization has implemented an HIV workplace programme since 2004. We carried out a retrospective analysis over 10 years. Data collected were initially essentially qualitative and process-oriented, but were complemented over the years by data on annual voluntary counselling and testing (VCT) uptake and on direct annual costs covering awareness, testing and antiretroviral therapy. The number of people covered by the programme grew from none in 2003 to 4,438 in 2015, with an increase in annual VCT uptake over the years increasing from 376 persons (14 %) in 2007 to 2,663 in 2015 (60 %). Over the years, the services were expanded from awareness raising to bringing VCT to the workplace, as well as offering testing and health coverage of other conditions and innovative approaches to facing challenges linked to situations of violence. Within its social responsibility framework, the ICRC has shown the importance and feasibility of a workplace HIV programme in conflict zones. A sustainable workplace programme in these conflict settings requires constant adaptation, with regular follow-up given the relatively high turnover of staff, and ensuring sustainable stocks of condoms and antiretroviral drugs.

    The Co-operative Programme on Decommissioning under the administration of the Radioactive Waste Management Committee of the OECD Nuclear Energy Agency (NEA) has recently completed sixteen years of operation. The Programme, which is essentially an information exchange programme between decommissioning projects, came into being in 1985. It has grown from an initial 10 decommissioning projects from 7 countries to 39 projects from 14 countries today. From purely information exchange to start with, the Programme has, in later years, been functioning as a voice for the collective expression of views of the implementers of nuclear decommissioning. During the first sixteen years of the operation of the Co-operative Programme, nuclear decommissioning has grown from local specialist activities within projects to a competitive commercial industry. By the dismantling and release from regulatory control of over a dozen diverse nuclear facilities, the Programme has been able to demonstrate in practice, that nuclear decommissioning can be performed safely both for the workers and the public, and that this can be done at reasonable costs in an environmentally friendly fashion. During the recent years, discussions and work within the Co-operative Programme, specially within some of the Task Groups, have had/are having effects and repercussions not just in the field of nuclear decommissioning, but can possibly affect activities and regulations in other industries. This paper describes how the Programme and its activities and procedures have evolved over the years and indicate the directions of developments in the organization and execution of decommissioning projects. Finally, it gives a brief overview of the achievements of the Cooperative Programme and visualizes future developments in the field of nuclear decommissioning.

    As part of the ongoing international DECOVALEX project, four research teams used five different models to simulate coupled thermal, hydrological, and mechanical (THM) processes near waste emplacement drifts of geological nuclear waste repositories. The simulations were conducted for two generic repository types, one with open and the other with back-filled repository drifts, under higher and lower postclosure temperatures, respectively. In the completed first model inception phase of the project, a good agreement was achieved between the research teams in calculating THM responses for both repository types, although some disagreement in hydrological responses is currently being resolved. In particular, good agreement in the basic thermal-mechanical responses was achieved for both repository types, even though some teams used relatively simplified thermal-elastic heat-conduction models that neglected complex near-field thermal-hydrological processes. The good agreement between the complex and simplified process models indicates that the basic thermal-mechanical responses can be predicted with a relatively high confidence level.

  9. History of Virtual Water , International Trade and Economic Metabolism at the Time Colonialism and a First Attempt to Assess Their Impact on Hydrologic Changes

    NASA Astrophysics Data System (ADS)

    Greco, F.

    2008-12-01

    This research considers the historical impact of virtual water into the geophysical arena by considering it as a human-led phenomenon that impacts the hydrologic system and, consequently, the environment as a whole. This paper is in line with the idea of including the humans into the water-balance model, and it is deepening the idea that this has to be done not only at the light of each watershed, but globally, looking at the role of water-trade embedded in food and tradable goods. Starting from a definition of what virtual water is, this research explores the role of crops export in the early U.S. Colonial time. As early as 1630 a huge biomass from here was already exported to the UK (the fur trade). In 1700 the tobacco export started, along with cereals exports and timber. An entire ecosystem has been "exported" in terms of water-embedded-in-goods. This was the beginning of a massive depletion of bio-mass stocks and flows, a raise in nitrogen discharge into the environment and its impact on the hydrological systems ( CUAHSI Summer Institute findings). Immigration and its effects on the water balance is also considered in this work. The experiment of interdisciplinary work of CUAHSI Summer Institute 2008 has proven that there is space for a historical reconstruction of evidence of human-led changes to the hydrological systems. This has been possible through the analysis of material stocks and flows, water-balance analysis of these stocks and flows, including human-led changes like international trade and population growth. This proposal will argue that these changes can also be identified by the term of 'socio- economic metabolism', in which societies are trading their goods internationally but taking the primary resources, including water, locally. This work will put the basis for the history of virtual water and its implications on both socio-economic metabolism and local geophysical changes.

    2012-04-01

    Recent years have brought a renewed focus on the issue of hydrologic similarity. What makes two catchments similar and what can we do with this understanding? The reason for this issue being so important lies at least partially in the need for generalization of results in a scientific field, which is limited through the large heterogeneity in our environment. The issue of hydrologic similarity is of course as old as hydrology itself, however, we believe that taking stock is needed from time to time to guide comparative hydrology efforts that have the potential to bring structure into the field of catchment hydrology. Apart from that, catchment similarity is the rational behind any attempt of predicting streamflow at ungauged basins, and a better understanding and definition of hydrologic similarity will enhance our ability to estimate water resources in absence of stream gauges. In this talk we focus on signatures of hydrologic extremes, i.e. flood and low flow characteristics of streamflow. Can similarity concepts relate catchment behavior under both high and low flow extremes? In how far do our understanding and our predictive capability regarding hydrologic extremes benefit from a holistic few of individual catchments, and from a comparative analysis between catchment? We will review different studies and present a meta analysis to highlight the proven and the potential benefit of taking a broader view.

    The Global Atmosphere Watch Programme, one of the tree research Programmes of the World Meteorological Organization (WMO/GAW) is the only existing long-term international global programme that coordinates observations and analysis of atmospheric composition changes. The GAW Programme builds on a partnership of more than 100 countries. Within its 25 years of existence WMO/GAW has matured to the system that provides reliable long-term high quality observations in support of international policy making. WMO/GAW includes globally coordinated observational network, complemented by a comprehensive quality assurance system and capacity development. In spite of the fact that GAW has embraced the IGACO strategy (Integrated Global Atmospheric Chemistry Observations), the programme in its current form still has a strong observational bias. Future development of WMO/GAW requires the further evolution of the programme concept toward "science for services". New challenges call for the changes in the GAW station requirements and data managements, for new approaches to collaboration with the contributing networks and better involvement of the modelling community. The programme structure is evolving to streamline better to user requirements with the move from precipitation chemistry to total deposition and from near-real-time data delivery to applications (modeling) requiring such data delivery. The updated concept of GAW will include more cross-cutting applications. A new category of local station is introduced to help with the verification of some applications including those related to urban areas and the impacts of urban complexes regionally and globally. The evolution of the GAW Programme towards user driven cross-cutting applications provides a new opportunity to the National Meteorological and Hydrological Services in partnership with other science - based institutions to increase their relevance to society.

    The Live.Learn.Laugh. phase 2 programme is a unique global partnership between FDI World Dental Federation and Unilever Oral Care which aims to provide measurable improvement of oral health on a global scale through encouraging twice-daily brushing with a fluoride toothpaste. It was based on international recommendations using the principles of health promotion within school for the implementation of preventive health strategies. This paper is an overview of the dental caries condition of children from 2012 to 2013 in nine countries included in four World Health Organisation (WHO) regions. A cross-sectional study was conducted in each country before the implementation of health-promotion measures focused on twice-daily toothbrushing with fluoride toothpaste. The sample was based on stratified sampling according to the WHO pathfinder recommendations. From a total of 7,949 children examined, there were 517 children (1-2 years of age), 1,667 preschool children (3-5 years of age) and 5,789 schoolchildren (6-13 years of age). The prevalence and severity of primary dental caries, early childhood caries and temporary dental caries were described using decayed, filled teeth (dft), permanent decayed, missing, filled teeth (DMFT) indices and the significant caries index (SCI). The major findings were a high prevalence of caries, identification of high-risk groups and inequality in the distribution of the severity of dental conditions. Aggregated data from this overview should provide justification for implementing an oral health programme. The main point is the need to retain and expand the community fluoridation programme as an effective preventive measure. At the individual level, the aggregated data identify the need for more targeted efforts to reach children early - especially among specific high-risk groups. PMID:25209648

    This paper explores public attitudes towards science and nature in twelve countries using data from the International Social Survey Programme environment modules of 1993, 2000, and 2010. Analysis of attitude items indicates technocentric and pessimistic dimensions broadly related to the Dominant Social Paradigm and New Environmental Paradigm. A bi-axial dimension scale is utilized to classify respondents among four environmental knowledge orientations. Discernible and significant patterns are found among countries and their populations. Relationships with other substantial variables in the surveys are discussed and findings show that the majority of industrialized countries are clustered in the rational ecologist categorization with respondents possessing stronger ecological consciousness and optimism towards the role of modern institutions, science, and technology in solving environmental problems.

    A major highlight of the Swedish national programme was the launch of the Odin Orbital Observatory in February 2001. The atmospheric profiles measured by Odin will be calibrated with rocket and balloon validation flights during the second half of 2001. A continuation of the satellite programme after Odin depends on the outcome of an ongoing assessment and an additional budget. The future ESA microgravity programme will be of high importance for European and Swedish science and applications using weightless conditions, and for the utilisation of the International Space Station (ISS). It should also make sure that the European independent capability for launching efficient sounding rockets is preserved and developed.

 Clinical practice guidelines are regarded as powerful tools to achieve effective health care. Although many countries have built up experience in the development, appraisal, and implementation of guidelines, until recently there has been no established forum for collaboration at an international level. As a result, in different countries seeking similar goals and using similar strategies, efforts have been unnecessarily duplicated and opportunities for harmonisation lost because of the lack of a supporting organisational framework. This triggered a proposal in 2001 for an international guidelines network built on existing partnerships. A baseline survey confirmed a strong demand for such an entity. A multinational group of guideline experts initiated the development of a non-profit organisation aimed at promotion of systematic guideline development and implementation. The Guidelines International Network (G-I-N) was founded in November 2002. One year later the Network released the International Guideline Library, a searchable database which now contains more than 2000 guideline resources including published guidelines, guidelines under development, "guidelines for guidelines", training materials, and patient information tools. By June 2004, 52 organisations from 27 countries had joined the network including institutions from Oceania, North America, and Europe, and WHO. This paper describes the process that led to the foundation of the G-I-N, its characteristics, prime activities, and ideas on future projects and collaboration. PMID:15576708

    An interdisciplinary approach is often described as a valuable strategy to assist in overcoming the existing and emerging challenges to water resource management. The development of educational approaches to instil a culture of interdisciplinarity in the future generation of water resource professionals will help to meet this strategic need. The Vienna Doctoral Programme on Water Resource Systems demonstrates how the adoption of an interdisciplinary education framework has been applied to a graduate programme in the water sciences. The interdisciplinary approach aims to provide doctoral research students with an understanding of the wide spectrum of processes relevant to water resource systems. This will enable them to bring together a range of ideas, strategies and methods to their current research and future careers. The education programme also aims to teach the softer skills required for successful interdisciplinary work such as the ability to communicate clearly with non-specialist professionals and the capacity to listen to and accommodate suggestions from experts in different disciplines, which have often not traditionally been grouped together. The Vienna Doctoral Programme achieves these aims through teaching an appreciation for a wide variety of approaches including laboratory analysis, field studies and numerical methods across the fields of hydrology, remote sensing, hydrogeology, structural mechanics, microbiology, water quality and resource management. Teaching takes the form of a detailed study programme on topics such as socio-economic concepts, resource and river basin management, modelling and simulation methods, health related water quality targets, urban water management, spatial data from remote sensing and basics for stochastic mechanics. Courses are also held by internationally recognised top scientists, and a guest scientist seminar series allows doctoral researchers to profit from the expertise of senior researchers from around the world

    Flood forecasting systems form a key part of ‘preparedness' strategies for disastrous floods and provide hydrological services, civil protection authorities and the public with information of upcoming events. Provided the warning leadtime is sufficiently long, adequate preparatory actions can be taken to efficiently reduce the impacts of the flooding. Following on the success of the use of ensembles for weather forecasting, the hydrological community now moves increasingly towards Hydrological Ensemble Prediction Systems (HEPS) for improved flood forecasting using operationally available NWP products as inputs. However, these products are often generated on relatively coarse scales compared to hydrologically relevant basin units and suffer systematic biases that may have considerable impact when passed through the non-linear hydrological filters. Therefore, a better understanding on how best to produce, communicate and use hydrologic ensemble forecasts in hydrological short-, medium- und long term prediction of hydrological processes is necessary. The "Hydrologic Ensemble Prediction Experiment" (HEPEX), is an international initiative consisting of hydrologists, meteorologist and end-users to advance probabilistic hydrologic forecast techniques for flood, drought and water management applications. Different aspects of the hydrological ensemble processor are being addressed including • Production of useful meteorological products relevant for hydrological applications, ranging from nowcasting products to seasonal forecasts. The importance of hindcasts that are consistent with the operational weather forecasts will be discussed to support bias correction and downscaling, statistically meaningful verification of HEPS, and the development and testing of operating rules; • Need for downscaling and post-processing of weather ensembles to reduce bias before entering hydrological applications; • Hydrological model and parameter uncertainty and how to correct and

    Before 1986, the development of tissue banking in China has been slow and relatively uncoordinated. Under the support of International Atomic Energy Agency (IAEA), Tissue Banking in China experienced rapid development. In this period, China Institute for Radiation Protection tissue bank mastered systematic and modern tissue banking technique by IAEA training course and gradually developed the first regional tissue bank (Shanxi Provincial Tissue Bank, SPTB) to provide tissue allograft. Benefit from training course, SPTB promoted the development of tissue transplantation by ways of training, brochure, advertisement and meeting. Tissue allograft transplantation acquired recognition from clinic and supervision and administration from government. Quality system gradually is developing and perfecting. Tissue allograft transplantation and tissue bank are developing rapidly and healthy. PMID:23959505

    Background The aim of this study was to determine if remotely sensed data and Digital Elevation Model (DEM) can test relationships between Culex quinquefasciatus and Anopheles gambiae s.l. larval habitats and environmental parameters within Internally Displaced People (IDP) campgrounds in Gulu, Uganda. A total of 65 georeferenced aquatic habitats in various IDP camps were studied to compare the larval abundance of Cx. quinquefasciatus and An. gambiae s.l. The aquatic habitat dataset were overlaid onto Land Use Land Cover (LULC) maps retrieved from Landsat imagery with 150 m × 150 m grid cells stratified by levels of drainage. The LULC change was estimated over a period of 14 years. Poisson regression analyses and Moran's I statistics were used to model relationships between larval abundance and environmental predictors. Individual larval habitat data were further evaluated in terms of their covariations with spatial autocorrelation by regressing them on candidate spatial filter eigenvectors. Multispectral QuickBird imagery classification and DEM-based GIS methods were generated to evaluate stream flow direction and accumulation for identification of immature Cx. quinquefasciatus and An. gambiae s.l. and abundance. Results The main LULC change in urban Gulu IDP camps was non-urban to urban, which included about 71.5 % of the land cover. The regression models indicate that counts of An. gambiae s.l. larvae were associated with shade while Cx. quinquefasciatus were associated with floating vegetation. Moran's I and the General G statistics for mosquito density by species and instars, identified significant clusters of high densities of Anopheles; larvae, however, Culex are not consistently clustered. A stepwise negative binomial regression decomposed the immature An. gambiae s.l. data into empirical orthogonal bases. The data suggest the presence of roughly 11% to 28 % redundant information in the larval count samples. The DEM suggest a positive correlation for Culex

    Ensemble forecast techniques are beginning to be used for hydrological prediction by operational hydrological services throughout the world. These techniques are attractive because they allow effects of a wide range of sources of uncertainty on hydrological forecasts to be accounted for. Not only does ensemble prediction in hydrology offer a general approach to probabilistic prediction, it offers a significant new approach to improve hydrological forecast accuracy as well. But, there are many scientific challenges that must be overcome to provide users with high quality hydrologic ensemble forecasts. A new international project the Hydrologic Ensemble Prediction Experiment (HEPEX) was started last year to organize the scientific community to meet these challenges. Its main objective is to bring the international hydrological community together with the meteorological community to demonstrate how to produce reliable hydrological ensemble for decisions for the benefit of public health and safety, the economy and the environment. Topics that will be addressed by the HEPEX scientific community include techniques for using weather and climate information in hydrologic prediction systems, new methods in hydrologic prediction, data assimilation issues in hydrology and hydrometeorology, verification and correction of ensemble weather and hydrologic forecasts, and better quantification of uncertainty in hydrological prediction. As pathway for addressing these topics, HEPEX will set up demonstration test bed projects and compile data sets for the intercomparison of coupled systems for atmospheric and hydrologic forecasting, and their assessment for meeting end users' needs for decision-making. Test bed projects have been proposed in North and South America, Europe, and Asia, and have a focus ranging from short-range flood forecasting to seasonal predictions for water supply. For example, within the United States, ongoing activities in seasonal prediction as part of the GEWEX

    The interdisciplinary postgraduate research and education programme - the Vienna Doctoral Programme on Water Resource Systems - was initiated in 2009. To date, 35 research students, three post-docs and ten faculty members have been engaged in the Programme, from ten research fields (aquatic microbiology, hydrology, hydro-climatology, hydro-geology, mathematical economics, photogrammetry, remote sensing, resource management, structural mechanics, and water quality). The Programme aims to develop research students with the capacity to work across the disciplines, to conduct cutting edge research and foster an international perspective. To do this, a variety of mechanisms are adopted that include research cluster groups, joint study sites, joint supervision, a basic study programme and a research semester abroad. The Programme offers a unique case study to explore if and how these mechanisms lead to research and education outcomes. Outcomes are grouped according to whether they are tangible (publications with co-authors from more than one research field, analysis of graduate profiles and career destinations) or non-tangible (interaction between researchers, networks and trust). A mixed methods approach that includes bibliometric analysis combined with interviews with students is applied. Bibliometric analysis shows that as the Programme has evolved the amount of multi-disciplinary work has increased (32% of the 203 full papers produced by the programme's researchers have authors from more than one research field). Network analysis to explore which research fields collaborate most frequently show that hydrology plays a significant role and has collaborated with seven of the ten research fields. Hydrology researchers seem to interact the most strongly with other research fields as they contribute understanding on water system processes. Network analysis to explore which individuals collaborate shows that much joint work takes place through the five research cluster

  11. Assessment of global reporting of adverse drug reactions for anti-malarials, including artemisinin-based combination therapy, to the WHO Programme for International Drug Monitoring

    2011-01-01

    Background In spite of enhanced control efforts, malaria remains a major public health problem causing close to a million deaths annually. With support from several donors, large amounts of artemisinin-based combination therapy (ACT) are being deployed in endemic countries raising safety concerns as little is known about the use of ACT in several of the settings where they are deployed. This project was undertaken to profile the provenance of the pharmacovigilance reporting of all anti-malarials, including ACT to the WHO adverse drug reaction (ADR) database (Vigibase™) over the past 40 years. Methods The WHO Programme for International Drug Monitoring, the Uppsala Monitoring Centre (UMC) provided anonymized extracts of Vigibase™ covering the period 1968-2008. All countries in the programme were clustered according to their malaria control phase and income status. The number of individual case safety reports (ICSRs) of anti-malarials was analyzed according to those clusters. Results From 1968 to 2008, 21,312 ICSRs suspecting anti-malarials were received from 64 countries. Low-income countries, that are also malaria-endemic (categorized as priority 1 countries) submitted only 1.2% of the ICSRs. Only 60 out of 21,312 ICSRs were related to ACT, 51 of which were coming from four sub-Saharan African countries. Although very few ICSRs involved artemisinin-based compounds, many of the adverse events reported were potentially serious. Conclusions This paper illustrates the low reporting of ADRs to anti-malarials in general and ACT in particular. Most reports were submitted by non-endemic and/or high-income countries. Given the current mix of large donor funding, the insufficient information on safety of these drugs, increasing availability of ACT and artemisinin-based monotherapies in public and private sector channels, associated potential for inappropriate use and finally a pipeline of more than 10 new novel anti-malarials in various stages of development, the

    2013-01-01

    To meet the expected shortfalls in the number of registered nurses throughout the coming decade Australian universities have been recruiting an increasing number of students from culturally and linguistically diverse (CaLD) backgrounds. Given that international and domestic students who use English as an additional language (EAL) complement the number of native English speaking nursing students, they represent a valuable nurse education investment. Although university programmes are in a position to meet the education and learning needs of native English speaking nursing students, they can experience considerable challenges in effectively equipping EAL students with the English and academic language skills for nursing studies and registration in Australia. However, success in a nursing programme and in preparing for nurse registration can require EAL students to achieve substantial literacy skills in English and academic language through their engagement with these tertiary learning contexts. This paper discusses the education implications for nursing programmes and EAL students of developing literacy skills through pre-registration nursing studies to meet the English language skills standard for nurse registration and presents intervention strategies for nursing programmes that aim to build EAL student capacity in using academic English.

    2014-12-01

    Hydrologic change has been detected in many regions of the world in the form of trends in annual streamflows, varying depths to the regional water table, or other alterations of the hydrologic balance. Most models used to investigate these changes implement sophisticated descriptions of the physical system but use simplified descriptions of the socioeconomic system. These simplifications come in the form of prescribed water diversions and land use change scenarios, which provide little insight into coupled natural-human systems and have limited predictive capabilities. We present an integrated model that adds realism to the description of the hydrologic system in agricultural regions by incorporating a component that updates the allocation of land and water to crops in response to hydroclimatic (water available) and economic conditions (prices of commodities and agricultural inputs). This component assumes that farmers allocate resources to maximize their net revenues, thus justifying the use of optimality conditions to constrain the parameters of an empirical production function that captures the economic behavior of farmers. Because the model internalizes the feedback between climate, agricultural markets, and farming activity into the hydrologic system, it can be used to understand to what extent human economic activity can exacerbate or buffer the regional hydrologic impacts of climate change in agricultural regions. It can also help in the attribution of causes of hydrologic change. These are important issues because local policy and management cannot solve climate change, but they can address land use and agricultural water use. We demonstrate the model in a case study.

    The Core Project Biospheric Aspects of the Hydrological Cycle (BAHC) of the International Geosphere Biosphere Programme (IGBP) addresses the biospheric aspects of the hydrological cycle through experiments and modelling of energy, water, carbon dioxide and sediment fluxes in the soil- vegetation-atmosphere system at a variety of spatial and temporal scales. Active regulation of water, energy and carbon dioxide fluxes by the vegetation make it an important factor in regulating the Earth's hydrological cycle and in the formation of the climate. Consequently, human induced conversion of vegetation cover is an important driver for climate change. A number of recent studies, discussed in this paper, emphasise the importance of the terrestrial biosphere for the climate system. Initially, these studies demonstrate the influence of the land surface on tropical weather and climate, revealing the mechanisms, acting at various scales, that connect increasing temperatures and decreasing rainfall to large-scale deforestation and other forms of land degradation. More recently, the significance of the land surface processes for water cycle and for weather and climate in temperate and boreal zones was demonstrated. In addition the terrestrial biosphere plays a significant role in the carbon dioxide fluxes and in global carbon balance. Recent work suggests that many ecosystems both in the tropics and in temperate zones may act as a substantial sink for carbon dioxide, though the temporal variability of this sink strength is yet unclear. Further, carbon dioxide uptake and evaporation by vegetation are intrinsically coupled, leading to links and feedbacks between land surface and climate that are hardly explored yet. Earth's vegetation cover and its changes owing to human impact have a profound influence on a lateral redistribution of water and transported constituents, such as nutrients and sediments, and acts therefore as an important moderator of Earth's biogeochemical cycles.

    2011-01-01

    A programmable oscillator is a frequency synthesizer with an output phase that tracks an arbitrary function. An offset, phase-locked loop circuit is used in combination with an error control feedback loop to precisely control the output phase of the oscillator. To down-convert the received signal, several stages of mixing may be employed with the compensation for the time-base distortion of the carrier occurring at any one of those stages. In the Goldstone Solar System Radar (GSSR), the compensation occurs in the mixing from an intermediate frequency (IF), whose value is dependent on the station and band, to a common IF used in the final stage of down-conversion to baseband. The programmable oscillator (PO) is used in the final stage of down-conversion to generate the IF, along with a time-varying phase component that matches the time-base distortion of the carrier, thus removing it from the final down-converted signal.

    The Pantanal hydrological cycle holds an important meaning in the Alto Paraguay Basin, comprising two areas with considerably diverse conditions regarding natural and water resources: the Plateau and the Plains. From the perspective of the ecosystem function, the hydrological flow in the relationship between plateau and plains is important for the creation of reproductive and feeding niches for the regional biodiversity. In general, river declivity in the plateau is 0.6 m/km while declivity on the plains varies from 0.1 to 0.3 m/km. The environment in the plains is characteristically seasonal and is home to an exuberant and abundant diversity of species, including some animals threatened with extinction. When the flat surface meets the plains there is a diminished water flow on the riverbeds and, during the rainy season the rivers overflow their banks, flooding the lowlands. Average annual precipitation in the Basin is 1,396 mm, ranging from 800 mm to 1,600 mm, and the heaviest rainfall occurs in the plateau region. The low drainage capacity of the rivers and lakes that shape the Pantanal, coupled with the climate in the region, produce very high evaporation: approximately 60% of all the waters coming from the plateau are lost through evaporation. The Alto Paraguay Basin, including the Pantanal, while boasting an abundant availability of water resources, also has some spots with water scarcity in some sub-basins, at different times of the year. Climate conditions alone are not enough to explain the differences observed in the Paraguay River regime and some of its tributaries. The complexity of the hydrologic regime of the Paraguay River is due to the low declivity of the lands that comprise the Mato Grosso plains and plateau (50 to 30 cm/km from east to west and 3 to 1.5 cm/km from north to south) as well as the area's dimension, which remains periodically flooded with a large volume of water.

    2016-04-01

    Hydrological extremes, from floods to droughts, pose one of the greatest challenges of the 21st century. Many of these challenges are associated with societal interactions with water, as people control or impact hydrological systems in a multitude of ways while they are also being affected and shaped by hydrological extremes, depending on their response to drought and flood events. However, the fact that the human and natural components of freshwater systems interact and co-evolve over time is often not taken into account. There is a need to study the two-way coupling between hydrology and society within a more comprehensive framework for hydrological extremes to anticipate future trajectories in a rapidly changing world. We present an interdisciplinary framework (and concepts) to identify internal controlling variables, processes and feedbacks, and the external system drivers and disturbances of the coupled human-water system with regard to hydrological extremes. To achieve this, the study (i) synthesizes existing research on coupled human-water system focusing on floods and droughts, (ii) analyzes hydrological extremes that have already occurred and their spatiotemporal patterns to investigate what patterns are observed in different regions of the world, and (iii) systematically describe the observed hydrological extremes, their causes and the interactions and feedbacks between hydrology and society. Advancing our understanding of mechanisms and feedbacks driving hydrological extremes is essential to better anticipate how the coupled human-water system will respond to future environmental change.

    In principle hydrologists are scientists that study relationships within the water cycle. Yet, current technology makes it tempting for hydrology students to lose their "hydrological perspective" and become instead full-time computer programmers or statisticians. I assert that students should ensure their hydrological perspective thrives, notwithstanding the importance and possibilities of current technology. This perspective is necessary to advance the science of hydrology. As other hydrologists have pondered similar views before, I make no claims of originality here. I just hope that in presenting my perspective on this issue I may spark the interest of other early career hydrologists.

    Business continuity programmes provide an important function within organisations, especially when aligned with and supportive of the organisation's goals, objectives and organisational culture. Continuity programmes for large, complex international organisations, unlike those for compact national companies, are more difficult to design, build, implement and maintain. Programmes for international organisations require attention to structural design, support across organisational leadership and hierarchy, seamless integration with the organisation's culture, measured success and demonstrated value. This paper details practical, but sometimes overlooked considerations for building successful global business continuity programmes. PMID:24854730

    Introduction HIV care and treatment programmes worldwide are transforming as they push to deliver universal access to essential prevention, care and treatment services to persons living with HIV and their communities. The characteristics and capacity of these HIV programmes affect patient outcomes and quality of care. Despite the importance of ensuring optimal outcomes, few studies have addressed the capacity of HIV programmes to deliver comprehensive care. We sought to describe such capacity in HIV programmes in seven regions worldwide. Methods Staff from 128 sites in 41 countries participating in the International epidemiologic Databases to Evaluate AIDS completed a site survey from 2009 to 2010, including sites in the Asia-Pacific region (n=20), Latin America and the Caribbean (n=7), North America (n=7), Central Africa (n=12), East Africa (n=51), Southern Africa (n=16) and West Africa (n=15). We computed a measure of the comprehensiveness of care based on seven World Health Organization-recommended essential HIV services. Results Most sites reported serving urban (61%; region range (rr): 33–100%) and both adult and paediatric populations (77%; rr: 29–96%). Only 45% of HIV clinics that reported treating children had paediatricians on staff. As for the seven essential services, survey respondents reported that CD4+ cell count testing was available to all but one site, while tuberculosis (TB) screening and community outreach services were available in 80 and 72%, respectively. The remaining four essential services – nutritional support (82%), combination antiretroviral therapy adherence support (88%), prevention of mother-to-child transmission (PMTCT) (94%) and other prevention and clinical management services (97%) – were uniformly available. Approximately half (46%) of sites reported offering all seven services. Newer sites and sites in settings with low rankings on the UN Human Development Index (HDI), especially those in the President's Emergency Plan

  14. Capacity building for hydrological change - using a blended learning approach

    NASA Astrophysics Data System (ADS)

    Nacken, H.

    2015-04-01

    Extreme hydrological events have always been a challenge to societies. There is growing evidence that hydrological extremes have already become more severe in some regions. The Middle East and North Africa (MENA) region is characterized as one of the world's most water-scarce and driest regions, with a high dependency on climate-sensitive agriculture. There is an urgent need for capacity building programmes that prepare water professionals and communities to deal with the expected hydrological changes and extremes. The most successful capacity building programmes are the country driven ones which involve a wide range of national stakeholders, have a high degree of in-country ownership and have an applicability character. The method of choice to set up such capacity building programmes will be through blended learning.

  16. EDIT: A New International Multicentre Programme to Develop and Evaluate Batteries of In Vitro Tests for Acute and Chronic Systemic Toxicity.

    PubMed

    Ekwall, B; Clemedson, C; Ekwall, B; Ring, P; Romert, L

    1999-01-01

    The Multicenter Evaluation of In Vitro Cytotoxicity (MEIC) programme provided a battery of three basal cytotoxicity tests with a good (R2 = 0.77) prediction of human acute lethal blood concentrations. The predictive power of this battery would be considerably improved by the addition of new supplementary in vitro tests. The development of these new tests will be facilitated by a close coupling of test development to evaluation. The Cytotoxicology Laboratory, Uppsala (CTLU), is therefore inviting all interested in vitro toxicologists to take part in the Evaluation-guided Development of In Vitro Toxicity and Toxicokinetic Tests (EDIT). All EDIT activities (subprojects) will be designed on a case-by-case basis, but will follow a common pattern. The CTLU will use the accumulated MEIC/EDIT data, and its experience from the previous MEIC evaluation, to suggest priority areas, i.e. the need for certain in vitro toxicity data/tests as supplements to existing in vitro models/batteries on human systemic toxicity. Detailed research programmes corresponding to these areas will be published on the Internet. The CTLU will also try to raise funds for some projects and will coordinate multilaboratory studies. Interested laboratories developing or already using priority tests are encouraged to join the subprojects and to test specific sets of substances (usually sets of MEIC reference chemicals) in their new assays. The CTLU will provide adequate human reference data and will also evaluate results as single components of complex models, together with the laboratory conducting the test. At present, ten priority areas have been identified: a) repeat dose toxicity in vitro; b) urgent mechanistic information from in vitro studies of protein denaturation, morphology of cell injury, differential toxicity between various rapidly measured endpoints (10-60 minutes) and 24-hour cytotoxicity, toxicity to aerobic cells, and discrimination between rapid and slow cytotoxic mechanisms; c) in

    European Earth observation program Copernicus is an EU-wide programme that integrates satellite data, in-situ data and modeling to provide user-focused information services to support policymakers, researchers, businesses and citizens. Land monitoring service and Emergency service are fully operational already, Atmosphere monitoring service and Marine environment monitoring service are preoperational and will become fully operational in the following year, while Climate change service and Security service are in an earlier development phase. New series of a number of dedicated satellite missions will be launched in the following years, operated by the European Space Agency and EUMETSAT, starting with Sentinel 1A satellite early this year. Ground based, air-borne and sea-borne in-situ data are provided by different international networks and organizations, EU member states networks etc. European Union is devoting a particular attention to secure a sustainable long-term operational provision of the services. Copernicus is also stated as a European Union’s most important contribution to Global Earth Observation System of Systems (GEOSS). The status and the recent development of the Copernicus programme will be presented, together with its future perspective. As Copernicus services have already demonstrated their usability and effectiveness, some interesting cases of their deployment will be presented. Copernicus free and open data policy, supported by a recently adopted EU legislative act, will also be presented.

  1. Hydrological and meteorological aspects of floods in the Alps: an overview

    NASA Astrophysics Data System (ADS)

    Bacchi, Baldassare; Ranzi, Roberto

    This introductory paper presents and summarises recent research on meteorological and hydrological aspects of floods in the Alps. The research activities were part of the international research project RAPHAEL (Runoff and Atmospheric Processes for flood HAzard forEcasting and controL) together with experiments within the Special Observing Period-SOP conducted in autumn 1999 for the Mesoscale Alpine Programme —MAP. The investigations were based on both field experiments and numerical simulations, using meteorological and hydrological models, of ten major floods that occurred in the past decade in the European Alps. The two basins investigated were the Ticino (6599 km2) at the Lago Maggiore outlet on the southern side of the Alps and the Ammer catchment (709 km2) in the Bavarian Alps. These catchments and their sub-catchments cover an appropriate range of spatial scales with which to investigate and test in an operational context the potential of both mesoscale meteorological and distributed hydrological models for flood forecasting. From the data analyses and model simulations described in this Special Issue, the major sources of uncertainties for flood forecasts in mid-size mountain basins are outlined and the accuracy flood forecasts is assessed.

    Evaluation is an essential management tool for the improvement of public health programmes or projects. As malaria morbidity and mortality continue to increase in most countries in Africa, international agencies and malaria control programme managers have identified the strengthening of programme evaluation as an important strategy for improving the efficiency and effectiveness of malaria control programmes. Managers can develop an evaluation strategy only after they have defined programme objectives and planned specific programme activities. Indicators should be directly related to programme objectives and should be selected on the basis of the following criteria: their validity; reliability; ability to detect change within a reasonable time period and as a result of successful programme implementation; ability to be interpreted; and usefulness in guiding programme change. Only those indicators that can be measured with available programme resources should be selected. Managers will also need to identify the sources of indicator data and to determine how often each indicator will be measured. Programme managers should develop criteria or indicators for the following: programme policies and plans; the process of programme implementation; the outcomes of malaria control interventions in disease management and prevention; and programme impact in terms of reductions in malaria-related mortality and morbidity. Key issues related to the management of evaluation activities within a national programme include the need to begin with available resources and build incrementally; to explore options for administering evaluation activities; to select, train and supervise staff who carry out evaluation activities; to develop quality control strategies; and to ensure that data are managed and communicated in ways that support effective programme decision-making. For evaluation to lead to improvements in malaria control programmes it must be clearly defined as a part of the

  3. Assessing The Role Of Integrated Learning In The BSc International Field Geosciences (IFG) Joint Degree Programme At University College Cork, the University of Montana and the University of Potsdam.

    2010-05-01

    The Department of Geology at University College Cork (UCC), Ireland, in conjunction with the Universities of Montana (UM) and Potsdam (UP) launched a new BSc in International Field Geosciences in Autumn 2008. In this program superb natural field geoscience laboratories available in Europe and the western United States are utilized as learning environments forming the basis for a ‘Joint' Bachelor of Science undergraduate degree. This programme focuses on the documentation, interpretation, and synthesis of critical geological issues in the field. It rests upon a backbone of existing modules that are the foundation of current geology programs at three partner institutions complemented by an emphasis on the development of field-based learning in an intercultural setting. The core curriculum is identical to that required for the existing BSc Geology at UCC except the third Year is spent abroad at UM while additional courses are taken at the UP at the start the fourth year. The mobility component of the programme is funded as part of a joint EU/US ATLANTIS project. The motivation for the new programme was primarily driven by the growing international demand for geoscientists with integrated field skills. Over the last two decades existing geoscience programmes in Europe and the US have tended to progressively reduce their field based learning components. One of the major reasons for this neglect is the increasing cost associated with physically transporting students into the field and maintaining a safe outdoor working environment. Heath and safety considerations in an increasingly litigious society have led to increasingly limited choices for suitable field areas in the last few decades. Lastly, recent technological advances such as GIS and various other forms of remote sensing have led to new ways of analyzing geospatial data that, while certainly useful, divert the attention of the Geoscience community away from collecting ‘ground truth' data and making direct

  5. Development of residency program guidelines for interaction with the pharmaceutical industry. Education Council, Residency Training Programme in Internal Medicine, Department of Medicine, McMaster University, Hamilton, Ont.

    PubMed Central

    1993-01-01

    Medical residency programs are likely to face increasing pressure to address their relations with the pharmaceutical industry. Our internal medicine residency program has developed guidelines that were adopted after extensive debate by residents and faculty members. The guidelines are based on the principles that residents and faculty should set the educational agenda and that the residency program should not allow gifts of any sort from industry to residents. Specific policies include obtaining and screening educational materials from the industry before residents are exposed to them, proscribing "drug lunches" and accepting industry sponsorship only when the residency program maintains complete control of the educational event being sponsored. The industry response to the guidelines was split; about half reacted negatively, and half found the guidelines acceptable. Our experience suggests that productive debate about guidelines for the interaction of residency programs with the pharmaceutical industry is possible and desirable and that explicit policies can clarify areas of ambiguity.

  7. A guidebook for insulated low-slope roof systems. IEA Annex 19, Low-slope roof systems: International Energy Agency Energy Conservation in Buildings and Community Systems Programme

    SciTech Connect

    Not Available

    1994-02-01

    Low-slope roof systems are common on commercial and industrial buildings and, to a lesser extent, on residential buildings. Although insulating materials have nearly always been a component of low-slope roofs, the amount of insulation used has increased in the past two decades because of escalation of heating and cooling costs and increased awareness of the need for energy conservation. As the amount of insulation has increased, the demand has intensified for design, installation, and maintenance information specifically for well-insulated roofs. Existing practices for design, installation, and maintenance of insulated roofs have evolved from experience. Typically, these practices feature compromises due to the different properties of materials making up a given roof system. Therefore, they should be examined from time to time to ensure that they are appropriate as new materials continue to enter the market and as the data base on existing systems expands. A primary purpose of this International Energy Agency (IEA) study is to assess current roofing insulation practices in the context of an accumulating data base on performance.

  8. Water Quality, Hydrology, and Simulated Response to Changes in Phosphorus Loading of Butternut Lake, Price and Ashland Counties, Wisconsin, with Special Emphasis on the Effects of Internal Phosphorus Loading in a Polymictic Lake

    Butternut Lake is a 393-hectare, eutrophic to hypereutrophic lake in northcentral Wisconsin. After only minor improvements in water quality were observed following several actions taken to reduce the nutrient inputs to the lake, a detailed study was conducted from 2002 to 2007 by the U.S. Geological Survey to better understand how the lake functions. The goals of this study were to describe the water quality and hydrology of the lake, quantify external and internal sources of phosphorus, and determine the effects of past and future changes in phosphorus inputs on the water quality of the lake. Since the early 1970s, the water quality of Butternut Lake has changed little in response to nutrient reductions from the watershed. The largest changes were in near-surface total phosphorus concentrations: August concentrations decreased from about 0.09 milligrams per liter (mg/L) to about 0.05 mg/L, but average summer concentrations decreased only from about 0.055-0.060 mg/L to about 0.045 mg/L. Since the early 1970s, only small changes were observed in chlorophyll a concentrations and water clarity (Secchi depths). All major water and phosphorus sources, including the internal release of phosphorus from the sediments (internal loading), were measured directly, and minor sources were estimated to construct detailed water and phosphorus budgets for the lake during monitoring years (MY) 2003 and 2004. During these years, Butternut Creek, Spiller Creek, direct precipitation, small tributaries and near-lake drainage area, and ground water contributed about 62, 20, 8, 7, and 3 percent of the inflow, respectively. The average annual load of phosphorus to the lake was 2,540 kilograms (kg), of which 1,590 kg came from external sources (63 percent) and 945 kg came from the sediments in the lake (37 percent). Of the total external sources, Butternut Creek, Spiller Creek, small tributaries and near-lake drainage area, septic systems, precipitation, and ground water contributed about

    Young, G.; Demuth, S.; Mishra, A.; Cudennec, C.

    2015-04-01

    This paper provides an introduction to the concepts of water security including not only the risks to human wellbeing posed by floods and droughts, but also the threats of inadequate supply of water in both quantity and quality for food production, human health, energy and industrial production, and for the natural ecosystems on which life depends. The overall setting is one of constant change in all aspects of Earth systems. Hydrological systems (processes and regimes) are changing, resulting from varying and changing precipitation and energy inputs, changes in surface covers, mining of groundwater resources, and storage and diversions by dams and infrastructures. Changes in social, political and economic conditions include population and demographic shifts, political realignments, changes in financial systems and in trade patterns. There is an urgent need to address hydrological and social changes simultaneously and in combination rather than as separate entities, and thus the need to develop the approach of `socio-hydrology'. All aspects of water security, including the responses of both UNESCO and the International Association of Hydrological Sciences (IAHS) to the concepts of socio-hydrology, are examined in detailed papers within the volume titled Hydrological Sciences and Water Security: Past, Present and Future.

    Benito, G.; Brázdil, R.; Herget, J.; Machado, M. J.

    2015-04-01

    In the last decades, the quantification of flood hydrological characteristics (peak discharge, hydrograph shape, and runoff volume) from documentary evidence has gained scientific recognition as a method to lengthen flood records of rare and extreme events. This paper describes the methodological evolution of the quantitative historical hydrology under the influence of developments in hydraulics and statistics. In the 19th century, discharge calculations based on flood marks was the only source of hydrological data for engineering design, but later was left aside on favour of systematic gauge records and conventional hydrological procedures. In the last two decades, there is growing scientific and public interest to understand long-term patterns of rare floods, maintain the flood heritage and memory of extremes, and to develop methods for deterministic and statistical application to different scientific and engineering problems. A compilation of 45 case studies across Europe with reconstructed discharges demonstrates that (1) in most cases present flood magnitudes are not unusual within the context of the last millennium, although recent floods may exceed past floods in some temperate European rivers (e.g. the Vltava and Po rivers), (2) frequency of extreme floods have decreased since the 1950s, although some rivers (e.g. the Gardon and Ouse rivers) show a reactivation of rare events over the last two decades. There is a great potential of gaining understanding of individual extreme events based on a combined multiproxy approach (palaeoflood and documentary records) providing high-resolution time flood series and their environmental and climatic changes; and to develop non-systematic and non-stationary statistical models based on relations of past floods with external and internal covariates under natural low-frequency climate variability.

    The Hydrologic Ensemble Prediction Experiment was established in March, 2004, at a workshop hosted by the European Center for Medium Range Weather Forecasting (ECMWF). With support from the US National Weather Service (NWS) and the European Commission (EC), the HEPEX goal was to bring the international hydrological and meteorological communities together to advance the understanding and adoption of hydrological ensemble forecasts for decision support in emergency management and water resources sectors. The strategy to meet this goal includes meetings that connect the user, forecast producer and research communities to exchange ideas, data and methods; the coordination of experiments to address specific challenges; and the formation of testbeds to facilitate shared experimentation. HEPEX has organized about a dozen international workshops, as well as sessions at scientific meetings (including AMS, AGU and EGU) and special issues of scientific journals where workshop results have been published. Today, the HEPEX mission is to demonstrate the added value of hydrological ensemble prediction systems (HEPS) for emergency management and water resources sectors to make decisions that have important consequences for economy, public health, safety, and the environment. HEPEX is now organised around six major themes that represent core elements of a hydrologic ensemble prediction enterprise: input and pre-processing, ensemble techniques, data assimilation, post-processing, verification, and communication and use in decision making. This poster presents an overview of recent and planned HEPEX activities, highlighting case studies that exemplify the focus and objectives of HEPEX.

It is composed of eight multidisciplinary projects that cover all the components of the Earth system (atmosphere, ocean, continental surfaces, lithosphere...) and their interactions, all the disciplines (physics, chemistry, marine biogeochemistry, biology, geology, sociology...) and different time scales. For example Hydrological cycle in the Mediterranean eXperiment (HyMeX) aims at improving the predictability of rainfall extreme events, and assessing the social and economic vulnerability to extreme events and adaptation capacity. Paleo Mediterranean Experiment (PaleoMeX) is dedicated to the study of the interactions between climate, societies and civilizations of the Mediterranean world during the last 10000 years. Many long term monitoring research networks are associated with MISTRALS, such as Mediterranean Ocean Observing System on Environment (MOOSE), Centre d'Observation Régional pour la Surveillance du Climat et de l'environnement Atmosphérique et océanographique en Méditerranée occidentale (CORSICA) and the environmental observations from Mediterranean Eurocentre for Underwater Sciences and Technologies (MEUST-SE). Therefore, the data generated or used by the different MISTRALS projects are very heterogeneous. They include in situ observations, satellite products, model outputs, social sciences surveys... Some datasets are automatically produced by operational networks, and others come from research instruments and analysis procedures. They correspond to different time scales (historical time series, observatories, campaigns...) and are managed by several data centres. They originate from many scientific communities, with different data sharing practices, specific expectations and using

  20. Doing hydrology forwards: Using field experimental data to inform a conceptual model of landscape driven hydrologic connectivity

    Given the known tradeoffs between hydrologic model complexity, efficiency, and predictive uncertainty there is an increasing desire to identify conceptual catchment models that accurately reflect catchment processes whilst preserving model identifiability. These models should specify the relationship between catchment form (including landscape topography, vegetation patterns, and stream networks) and hydrologic functioning (including streamflow patterns). We present a new hydrologic modeling approach that uses the distribution of landscape elements along the stream network as a template by which landscape-scale hydrologic connectivity and catchment runoff can be simulated. Here, we define hydrologic connectivity as the transient hydrological linkages between landscape elements and the stream. Our conceptualization emphasizes the importance of hydrologic connections between hillslope-riparian-stream (HRS) zones. Observations indicate that it is the frequency of these HRS hydrologic connections that drive aggregate catchment runoff response, rather than the magnitude of flux at any one connection. We applied the model to the Stringer Creek watershed of the Tenderfoot Creek Experimental Forest (TCEF), located in central Montana, USA. Detailed field observations were used to inform the underpinnings of the model and to corroborate internal consistency of the model's simulations. The ability of the model to simulate internal dynamics without conditioning the parameters on these data indicate the potential of this model to be more convincingly extrapolated to other hydrologic conditions and tested at catchments of varying topographic structure. Current and future work is aimed at further developing the modeling approach and testing the limits of its applicability across space and time.

  1. History of forest hydrology

    McCulloch, James S. G.; Robinson, Mark

    1993-10-01

    Hydrology as a science and a technology is examined, as are some of the myths on the role of forests in hydrology and water resources. The history of catchment area research is traced, in Europe, in the USA and in East Africa, with particular reference to forest hydrology and, in the earlier years, to water quantity rather than water quality. The importance of associating physical process studies with hydrological systems' investigations, to enhance understanding of why particular catchments behave as they do, is stressed. Recent advances in hydrochemistry have been exploited to elucidate water flow paths within experimental catchments. Stimulated by requirements for research into acidification of surface waters, research catchments have proved to be valuable outdoor laboratories from which a much improved understanding of the flow processes has been achieved. Conflicting claims about the impacts of forestry are described and discussed.

  2. The Experimental Hydrology Wiki

    2013-04-01

    The "Experimental Hydrology Wiki" is a forum for hydrologists to learn about, recommend, question and discuss new and established, basic and advanced methods and equipment for hydrological research. As a database of "lessons learned" it does not only contain short descriptions of specific experimental equipment but also information on encountered errors and problems and recommendations on how to deal with them. This makes valuable personal field experience accessible to a wider audience. The Wiki allows experimentalists to share and find solutions for common problems and thus helps us in not making the same mistakes others have made before us. At the same time modellers can use this platform to find information on sources of error and uncertainty in the data they use for model validation and calibration. The general idea and layout of the Experimental Hydrology Wiki is presented here along with an invitation to all experimental hydrologists to contribute their knowledge and experiences! http://www.experimental- hydrology.net/

  3. Remote sensing in hydrology

    1988-07-01

    The "Electronic Age" offers new and attractive opportunities to hydrologists for remote sensing (RS) of hydrological data. A discussion of hydrologically relevant platforms and sensors and the type of electromagnetic signals used by such sensors is followed by an analysis of the structure of mathematical hydrologic models which use RS information either as input or to provide a basis for model parameter estimation. Three examples of RS application in hydrological modeling are given: (1) model parameter estimation with the aid of multispectral Landsat satellite data; (2) computation of historic monthly runoff for design purposes with the aid of a lumped system model using NOAA infrared satellite data as input; and (3) real-time flood forecasting applying a distributed system model using radar rainfall measurements as input. Further applications of RS information in hydrology are discussed in the field of evapotranspiration, soil moisture, rainfall, surface water, snow and ice, sediments and water quality. A brief discussion of RS data availability and the hardware and software required is followed by an assessment of future opportunities. The potential of passive and active microwave sensors for hydrological applications is emphasized.

    The challenge for nursing leaders responsible for workforce planning is to predict the knowledge, skills and abilities required to lead future healthcare delivery systems effectively. Succession planning requires a constant, competitive pool of qualified nursing leader candidates, and retention of those interested in career growth. Formal nursing leadership education in the United States is available through graduate education and professional nursing organisation programmes, such as the Emerging Nurse Leader Institute of the American Organization of Nurse Executives. However, there is also a need for local development programmes tailored to the needs of individual organisations. Leaders at Geisinger Health System, one of the largest rural health systems in the US, identified the need for an internal professional development scheme for nurses. In 2013 the Nurses Emerging as Leaders programme was developed to prepare nurse leaders for effective leadership and successful role transition. This article describes the programme and an evaluation of its effectiveness. PMID:26927790

    The JOSHUA system routines (JS routines) can be used to manage a JOSHUA data base and execute JOSHUA modules on VAX/VMS and IBM/MVS computer systems. This manual provides instructions for using the JS routines and information about the internal data structures and logic used by the routines. It is intended for use primarily by JOSHUA systems programmers, however, advanced applications programmers may also find it useful. The JS routines are, as far as possible, written in ANSI FORTRAN 77 so that they are easily maintainable and easily portable to different computer systems. Nevertheless, the JOSHUA system provides features that are not available in ANSI FORTRAN 77, notably dynamic module execution and a data base of named, variable length, unformatted records, so some parts of the routines are coded in nonstandard FORTRAN or assembler (as a last resort). In most cases, the nonstandard sections of code are different for each computer system. To make it easy for programmers using the JS routines to avoid naming conflicts, the JS routines and common block all have six character names that begin with the characters {open_quotes}JS.{close_quotes} Before using this manual, one should be familiar with the JOSHUA system as described in {open_quotes}The JOSHUA Users` Manual,{close_quotes} ANSI FORTRAN 77, and at least one of the computer systems for which the JS routines have been implemented.

    The International Programme for Chemical Safety (IPCS) has developed a set of guidelines ("the Guidance") for the establishment of Chemical-Specific Adjustment Factors (CSAFs) for in the assessment of toxicity risk to the human population as a result of chemical exposure. The development of case studies is encouraged in the Guidance document and comments on them have been encouraged by the IPCS. One provision in the Guidance is for the determination of CSAFs based on human data. We present a case study of the use of the Guidance for the determination of the CSAF for ethylene glycol (EG) primarily utilizing clinically obtained data. The most relevant endpoint for this analysis was deemed to be acute renal injury. These data were applied based on an assessment of the known pharmaco/toxico-kinetic properties of EG. Because of the lack of both bioaccumulation of EG and reports of chronic or progressive renal injury from EG, it was concluded that the most appropriate model of chronic exposure is one of repeated acute episodes. The most relevant exposure metric was determined to be plasma glycolate concentration. Based on a prospective human study of EG-poisoned patients, the NOAEL for glycolate was found to be 10.1 mM. This value is similar to that obtained from animal data. The application of the Guidelines to this data resulted in a CSAF of 10.24, corresponding to a daily EG dose of 43.7 mg/kg/day. In 2000, Health Canada (HC) produced an animal data-based analysis of the maximum tolerated dose of EG. The results of our analysis are compared with those of HC, and the strengths and weaknesses of these two data types related to EG are discussed. PMID:15990139

  9. Studying the Hydrology of Landslides: Pore Water Pressure, Preferential Flow and Feedbacks Between Slope Displacement and Hillslope Hydrology

    NASA Astrophysics Data System (ADS)

    Bogaard, T.; Greco, R.

    2014-12-01

    Hydrology is one of the most important triggering factors for slope destabilization. When a slope becomes unstable, cracks and fissures develop during slope deformation. These discontinuities affect both geotechnical and hydrological conditions of the slope. The crucial role of water flow, and especially the important role of preferential flow in unstable slopes, is generally recognized. However, in hydrological modelling, the unstable slope is characterized using static subsurface properties. The dynamic feedback between slope deformation and slope hydrology, being positive or negative depending on other geotechnical conditions, is not taken into account although it influences the pore pressure distribution and as such the overall stability. This research aims to highlight and quantify the dynamic nature of the subsurface hydrological conditions in unstable slopes. We focus on the role preferential flow has on slope destabilization and more specifically on the feedbacks between differential displacement and hydrological behaviour of the subsurface in natural slopes. We will present examples of field experimental work where we measured the hydrological influence of fissures, theoretical analysis and case study modelling of combined hydrology and slope stability, including feedbacks. The results show the subtle trade-off of increased infiltration and storage capacity in a slope and the increased drainage capacity of well connected preferential flow paths. We will furthermore highlight the current status of our knowledge as well as identify the knowledge gaps we face and the importance of cross- and multidisciplinary approach to better understand the internal dynamics of slope deformation and hillslope hydrology.

    The Hydrologic Ensemble Prediction Experiment was established in March, 2004, at a workshop hosted by the European Center for Medium Range Weather Forecasting (ECMWF), and co-sponsored by the US National Weather Service (NWS) and the European Commission (EC). The HEPEX goal was to bring the international hydrological and meteorological communities together to advance the understanding and adoption of hydrological ensemble forecasts for decision support. HEPEX pursues this goal through research efforts and practical implementations involving six core elements of a hydrologic ensemble prediction enterprise: input and pre-processing, ensemble techniques, data assimilation, post-processing, verification, and communication and use in decision making. HEPEX has grown through meetings that connect the user, forecast producer and research communities to exchange ideas, data and methods; the coordination of experiments to address specific challenges; and the formation of testbeds to facilitate shared experimentation. In the last decade, HEPEX has organized over a dozen international workshops, as well as sessions at scientific meetings (including AMS, AGU and EGU) and special issues of scientific journals where workshop results have been published. Through these interactions and an active online blog (www.hepex.org), HEPEX has built a strong and active community of nearly 400 researchers & practitioners around the world. This poster presents an overview of recent and planned HEPEX activities, highlighting case studies that exemplify the focus and objectives of HEPEX.

  11. Hydrological extremes and security

    2015-04-01

    Economic losses caused by hydrological extremes - floods and droughts - have been on the rise. Hydrological extremes jeopardize human security and impact on societal livelihood and welfare. Security can be generally understood as freedom from threat and the ability of societies to maintain their independent identity and their functional integrity against forces of change. Several dimensions of security are reviewed in the context of hydrological extremes. The traditional interpretation of security, focused on the state military capabilities, has been replaced by a wider understanding, including economic, societal and environmental aspects that get increasing attention. Floods and droughts pose a burden and serious challenges to the state that is responsible for sustaining economic development, and societal and environmental security. The latter can be regarded as the maintenance of ecosystem services, on which a society depends. An important part of it is water security, which can be defined as the availability of an adequate quantity and quality of water for health, livelihoods, ecosystems and production, coupled with an acceptable level of water-related risks to people, environments and economies. Security concerns arise because, over large areas, hydrological extremes - floods and droughts - are becoming more frequent and more severe. In terms of dealing with water-related risks, climate change can increase uncertainties, which makes the state's task to deliver security more difficult and more expensive. However, changes in population size and development, and level of protection, drive exposure to hydrological hazards.

    USGS Publications Warehouse

    Lu, Ning; Godt, Jonathan

    2012-01-01

    Landslides are caused by a failure of the mechanical balance within hillslopes. This balance is governed by two coupled physical processes: hydrological or subsurface flow and stress. The stabilizing strength of hillslope materials depends on effective stress, which is diminished by rainfall. This book presents a cutting-edge quantitative approach to understanding hydro-mechanical processes across variably saturated hillslope environments and to the study and prediction of rainfall-induced landslides. Topics covered include historic synthesis of hillslope geomorphology and hydrology, total and effective stress distributions, critical reviews of shear strength of hillslope materials and different bases for stability analysis. Exercises and homework problems are provided for students to engage with the theory in practice. This is an invaluable resource for graduate students and researchers in hydrology, geomorphology, engineering geology, geotechnical engineering and geomechanics and for professionals in the fields of civil and environmental engineering and natural hazard analysis.

    Stacey, J. M.; Johnston, E. J.; Girard, M. A.; Regusters, H. A.

    1985-01-01

    Microwave hydrology, as the term in construed in this trilogy, deals with the investigation of important hydrological features on the Earth's surface as they are remotely, and passively, sensed by orbiting microwave receivers. Microwave wavelengths penetrate clouds, foliage, ground cover, and soil, in varying degrees, and reveal the occurrence of standing liquid water on and beneath the surface. The manifestation of liquid water appearing on or near the surface is reported by a microwave receiver as a signal with a low flux level, or, equivalently, a cold temperature. Actually, the surface of the liquid water reflects the low flux level from the cosmic background into the input terminals of the receiver. This trilogy describes and shows by microwave flux images: the hydrological features that sustain Lake Baykal as an extraordinary freshwater resource; manifestations of subsurface water in Iran; and the major water features of the Congo Basin, a rain forest.

The team, the objectives, the work breakdown structure, the methodology, the technical approaches, the first results as well as the status and the upcoming milestones of the project will be presented. This study is part of SEOM, Scientific Exploitation of Operational Missions, an ESA programme element which aims at expanding the international research community, strengthening the leadership of the European EO research community and addressing new scientific researches. This Research and Development study not only intends to make the best use of all recent improvements in altimetry but also clearly pushes for major breakthroughs that should boost the scientific use of the SAR altimetry data in hydrology. The stakes are high in the context of climate change, as scientists need to improve their analyses of water stocks and exchanges over wide geographical regions. The study focuses on three main variables of interest in hydrology: river stage, river discharge and lake level, which are part of the Terrestrial Essential Climate Variables (TECV) defined by GCOS. It also is the scientific step towards a future Inland Water dedicated processor on the Sentinel-3 ground segment. The main characteristics of the project will be summarized. Cooperation with the scientific community will be encouraged. Project documents available at the website (ATBD for example) will go through a critical review outside the project team so as to collect feedback. Valuable feedback will be taken into account so as to provide a new processing chain prototype that should be capable of providing high quality water heights, making it possible to couple it with the hydrological dynamic and semi-distributed model HYPE (Hydrological Predictions for the Environment).

    SciTech Connect

    Kane, D.L.

    1988-01-01

    The behavior of arctic ecosystems is directly related to the ongoing physical processes of heat and mass transfer. Furthermore, this system undergoes very large fluctuations in the surface energy balance. The buffering effect of both snow and the surface organic soils can be seen by looking at the surface and 40 cm soil temperatures. The active layer, that surface zone above the permafrost table, is either continually freezing or thawing. A large percentage of energy into and out of a watershed must pass through this thin veneer that we call the active layer. Likewise, most water entering and leaving the watershed does so through the active layer. To date, we have been very successful at monitoring the hydrology of Imnavait Creek with special emphasis on the active layer processes. The major contribution of this study is that year-round hydrologic data are being collected. An original objective of our study was to define how the thermal and moisture regimes within the active layer change during an annual cycle under natural conditions, and then to define how the regime will be impacted by some imposed terrain alteration. Our major analysis of the hydrologic data sets for Imnavait Creek have been water balance evaluations for plots during snowmelt, water balance for the watershed during both rainfall and snowmelt, and the application of a hydrologic model to predict the Imnavait Creek runoff events generated by both snowmelt and rainfall.

  7. Hydrologic classification of Bristol Bay, Alaska using hydrologic landscapes

    NASA Astrophysics Data System (ADS)

    Todd, J.; Wigington, P. J.; Sproles, E.

    2013-12-01

    The use of hydrologic landscapes has proven to be a useful tool for broad scale assessment and classification of landscapes across the United States. These classification systems help organize larger geographical areas into areas of similar hydrologic characteristics based on climate, terrain and underlying geology. Such characterization of landscapes into areas of common hydrologic patterning is particularly instructive in regions where site specific hydrologic data is sparse or spatially incomplete. By using broad scale landscape metrics to organize the landscape into discrete, characterized units, natural resources managers can gain valuable understanding of landscape patterning and how locations may be differentially affected by a variety of environmental stressors ranging from land use change to management of salmon resources to climate change. Further, the heterogeneity of aquatic habitats and undisturbed hydrologic regimes within this area are a known principal driver for its region-wide fisheries stability. The use of hydrologic landscapes offers an opportunity to better characterize the hydrologic and landscape influences on structuring biotic populations at a regional scale. We have undertaken a hydrologic landscape approach for the Bristol Bay region of Alaska to gain a better understanding of the overall hydrologic environment found in this region since its hydrologic patterning plays a principal role in structuring its world-renowned salmon fishery. Heretofore, a characterization of the entire Bristol Bay region into discrete hydrologic units has not been undertaken. Our classification structure includes indices of annual climate and seasonality, terrain, and geology. Following categorization of landscape units, we compared hydrologic landscape units to locations of available long term streamflow for characterization of expected hydrologic behavior. This demonstration of hydrologic landscapes in Bristol Bay, Alaska shows the utility of using large

    Reference hydrologic networks (RHNs) can play an important role in monitoring for changes in the hydrological regime related to climate variation and change. Currently, the literature concerning hydrological response to climate variations is complex and confounded by the combinations of many methods of analysis, wide variations in hydrology, and the inclusion of data series that include changes in land use, storage regulation and water use in addition to those of climate. Three case studies that illustrate a variety of approaches to the analysis of data from RHNs are presented and used, together with a summary of studies from the literature, to develop approaches for the investigation of changes in the hydrological regime at a continental or global scale, particularly for international comparison. We present recommendations for an analysis framework and the next steps to advance such an initiative. There is a particular focus on the desirability of establishing standardized procedures and methodologies for both the creation of new national RHNs and the systematic analysis of data derived from a collection of RHNs.

  10. Development of hydrologic landscape regions for classifying hydrologic permanace and hydrological-ecological interactions

    EPA Science Inventory

    In a 2001 paper, Winter proposed the concept of the hydrologic landscape unit as a fundamental unit composed of an upland and lowland separated by a steeper slope. Winter suggested that this concept could be useful for hydrologic research, data analysis, and comparing hydrologic...
