Gaining accuracy with indoor positioning of individuals is important as many location-based services rely on the user's current position to provide them with useful services. Many researchers have studied indoor positioning techniques based on WiFi and Bluetooth. However, they have disadvantages such as low accuracy or high cost. In this paper, we propose an indoor positioning system in which visible light radiated from light-emitting diodes is used to locate the position of receivers. Compared with existing methods using light-emitting diode light, we present a high-precision and simple implementation collaborative indoor visible light positioning system based on an improved spring model. We first estimate coordinate position information using the visible light positioning system, and then use the spring model to correct positioning errors. The system can be employed easily because it does not require additional sensors and the occlusion problem of visible light would be alleviated. We also describe simulation experiments, which confirm the feasibility of our proposed method.

In the next generation of Infocommunications, mobile Internet-enabled devices and third generation mobile communication networks have become reality, location based services (LBS) are expected to be a major area of growth. Providing information, content and services through positioning technologies forms the platform for new services for users and developers, as well as creating new revenue channels for service providers. These crucial advances in location based services have opened up new opportunities in real time patient tracking for personal healthcare applications. In this paper, a hybrid mobile-based location technique using the global positioning system (GPS) and cellular mobile network infrastructure is employed to provide the location tracking capability. This function will be integrated into the patient location tracking system (PLTS) to assist caregivers or family members in locating patients such as elderly or dependents when required, especially in emergencies. The capability of this PLTS is demonstrated through a series of location detection tests conducted over different operating conditions. Although the model is at its initial stage of development, it has shown relatively good accuracy for position tracking and potential of using integrated wireless technology to enhance the existing personal healthcare communication system through location based services.

In order to provide the seamless navigation and positioning services for indoor environments, an indoor location based service (LBS) test bed is developed to integrate the indoor positioning system and the indoor three-dimensional (3D) geographic information system (GIS). A wireless sensor network (WSN) is used in the developed indoor positioning system. Considering the power consumption, in this paper the ZigBee radio is used as the wireless protocol, and the received signal strength (RSS) fingerprinting positioning method is applied as the primary indoor positioning algorithm. The matching processes of the user location include the nearest neighbor (NN) algorithm, the K-weighted nearest neighbors (KWNN) algorithm, and the probabilistic approach. To enhance the positioning accuracy for the dynamic user, the particle filter is used to improve the positioning performance. As part of this research, a 3D indoor GIS is developed to be used with the indoor positioning system. This involved using the computer-aided design (CAD) software and the virtual reality markup language (VRML) to implement a prototype indoor LBS test bed. Thus, a rapid and practical procedure for constructing a 3D indoor GIS is proposed, and this GIS is easy to update and maintenance for users. The building of the Department of Aeronautics and Astronautics at National Cheng Kung University in Taiwan is used as an example to assess the performance of various algorithms for the indoor positioning system.

Considerable expectations have been placed on information and communication technology (ICT) in improving the processes and quality of healthcare. Our purpose was to find out which element is found positive in healthcare ICT implementation. An online questionnaire on e-Health implementation submitted to all Finnish public health service providers and a sample from the private sector included an open question about which the electronic working methods, systems, or applications have most positively influenced the fluency or quality of service processes. The electronic health record was mentioned as an item that has positive influence by 52% of the respondents from the hospital districts, 27% of those from the primary healthcare centers, and 38% of those from the private providers. Digital radiology systems (including teleradiology) were mentioned by 52% of the hospital districts and 27% of the primary healthcare centers. The figures for digital laboratory systems (including telelaboratory) were 5% and 11%, respectively. The figures for teleradiology itself were 5% for the hospital districts and 15% for the primary healthcare centers; the figures for telelaboratory systems were 5% and 9%, respectively. The specialized healthcare seem to experience intraorganizational electronic services integrated to the electronic health record, such as digital radiology and laboratory services as exerting a positive influence, whereas the primary healthcare find such influence from different functions such as interorganizational data exchange and telemedicine services. These might indicate where the efforts should be focused when implementing ICT in healthcare.

No previous studies have addressed the integrated relationships among system quality, service quality, job satisfaction, and system performance; this study attempts to bridge such a gap with evidence-based practice study. The convenience sampling method was applied to the information system users of three hospitals in southern Taiwan. A total of 500 copies of questionnaires were distributed, and 283 returned copies were valid, suggesting a valid response rate of 56.6%. SPSS 17.0 and AMOS 17.0 (structural equation modeling) statistical software packages were used for data analysis and processing. The findings are as follows: System quality has a positive influence on service quality (γ11= 0.55), job satisfaction (γ21= 0.32), and system performance (γ31= 0.47). Service quality (β31= 0.38) and job satisfaction (β32= 0.46) will positively influence system performance. It is thus recommended that the information office of hospitals and developers take enhancement of service quality and user satisfaction into consideration in addition to placing b on system quality and information quality when designing, developing, or purchasing an information system, in order to improve benefits and gain more achievements generated by hospital information systems.

Systems engineering (SE) professionals strive to develop new techniques to enhance the value of contributions to multidisciplinary smart product design teams. Products and services designers challenge themselves to search beyond the traditional design concept of addressing the physical, social, and cognitive factors. This paper covers the application of embedded user-centered systems engineering design practices into work processes based on the ISO 13407 framework [20] to support smart systems and services design and development. As practitioners collaborate to investigate alternative smart product designs, they concentrate on creating valuable products which will enhance positive interaction. This paper capitalizes on the need to follow a user-centered SE approach to smart products design [4, 22]. Products and systems intelligence should embrace a positive approach to user-centered design while improving our understanding of usable value-adding, experience and extending our knowledge of what inspires others to design enjoyable services and products.

The impact of emotional involvement on online service buying decisions: an event-related potentials perspective

When examining a buying process, changes in human brain signals and their event-related potential (ERP) components can be considered a reflection of the consumers’ emotions. In this experiment, participants were shown 12 products and related services that were available for purchase. After recording ERP components, we used a questionnaire to measure the individuals’ emotional involvement toward the services (i.e. the same services shown in the stimuli) of the 12 products to measure the emotional valence of the services. The emotional ERP components and the late positive potential (LPP) were elicited under the service conditions and distributed over the left frontal regions. We determined that the services may evoke an LPP and that services with a high emotional value may evoke a larger LPP, which suggests that positive emotion may be measured using the LPP amplitude in the left frontal regions. This result helps elucidate whether positive emotions are stimulated during the product-service system decision-making process and helps understand the emotional valences of different services. Our analysis of the emotional motivation of the consumer suggests that the LPP may be useful as an emotional indicator for measuring consumers’ evaluation of services that provides a neural view of product-service system buying decisions.

The regional service of the Chinese BeiDou satellite navigation system is now in operation with a constellation including five Geostationary Earth Orbit satellites (GEO), five Inclined Geosynchronous Orbit (IGSO) satellites and four Medium Earth Orbit (MEO) satellites. Besides the standard positioning service with positioning accuracy of about 10 m, both precise relative positioning and precise point positioning are already demonstrated. As is well known, precise orbit and clock determination is essential in enhancing precise positioning services. To improve the satellite orbits of the BeiDou regional system, we concentrate on the impact of the tracking geometry and the involvement of MEOs, and on the effect of integer ambiguity resolution as well. About seven weeks of data collected at the BeiDou Experimental Test Service (BETS) network is employed in this experimental study. Several tracking scenarios are defined, various processing schemata are designed and carried out; and then, the estimates are compared and analyzed in detail. The results show that GEO orbits, especially the along-track component, can be significantly improved by extending the tracking network in China along longitude direction, whereas IGSOs gain more improvement if the tracking network extends in latitude. The involvement of MEOs and ambiguity-fixing also make the orbits better. PMID:23529116

The GFZ real-time GNSS precise positioning service system and its adaption for COMPASS

2013-03-01

Motivated by the IGS real-time Pilot Project, GFZ has been developing its own real-time precise positioning service for various applications. An operational system at GFZ is now broadcasting real-time orbits, clocks, global ionospheric model, uncalibrated phase delays and regional atmospheric corrections for standard PPP, PPP with ambiguity fixing, single-frequency PPP and regional augmented PPP. To avoid developing various algorithms for different applications, we proposed a uniform algorithm and implemented it into our real-time software. In the new processing scheme, we employed un-differenced raw observations with atmospheric delays as parameters, which are properly constrained by real-time derived global ionospheric model or regional atmospheric corrections and by the empirical characteristics of the atmospheric delay variation in time and space. The positioning performance in terms of convergence time and ambiguity fixing depends mainly on the quality of the received atmospheric information and the spatial and temporal constraints. The un-differenced raw observation model can not only integrate PPP and NRTK into a seamless positioning service, but also syncretize these two techniques into a unique model and algorithm. Furthermore, it is suitable for both dual-frequency and sing-frequency receivers. Based on the real-time data streams from IGS, EUREF and SAPOS reference networks, we can provide services of global precise point positioning (PPP) with 5-10 cm accuracy, PPP with ambiguity-fixing of 2-5 cm accuracy, PPP using single-frequency receiver with accuracy of better than 50 cm and PPP with regional augmentation for instantaneous ambiguity resolution of 1-3 cm accuracy. We adapted the system for current COMPASS to provide PPP service. COMPASS observations from a regional network of nine stations are used for precise orbit determination and clock estimation in simulated real-time mode, the orbit and clock products are applied for real-time precise point positioning. The simulated real-time PPP service confirms that real-time positioning services of accuracy at dm-level and even cm-level is achievable with COMPASS only.

Smart Device-Supported BDS/GNSS Real-Time Kinematic Positioning for Sub-Meter-Level Accuracy in Urban Location-Based Services.

Using mobile smart devices to provide urban location-based services (LBS) with sub-meter-level accuracy (around 0.5 m) is a major application field for future global navigation satellite system (GNSS) development. Real-time kinematic (RTK) positioning, which is a widely used GNSS-based positioning approach, can improve the accuracy from about 10-20 m (achieved by the standard positioning services) to about 3-5 cm based on the geodetic receivers. In using the smart devices to achieve positioning with sub-meter-level accuracy, a feasible solution of combining the low-cost GNSS module and the smart device is proposed in this work and a user-side GNSS RTK positioning software was developed from scratch based on the Android platform. Its real-time positioning performance was validated by BeiDou Navigation Satellite System/Global Positioning System (BDS/GPS) combined RTK positioning under the conditions of a static and kinematic (the velocity of the rover was 50-80 km/h) mode in a real urban environment with a SAMSUNG Galaxy A7 smartphone. The results show that the fixed-rates of ambiguity resolution (the proportion of epochs of ambiguities fixed) for BDS/GPS combined RTK in the static and kinematic tests were about 97% and 90%, respectively, and the average positioning accuracies (RMS) were better than 0.15 m (horizontal) and 0.25 m (vertical) for the static test, and 0.30 m (horizontal) and 0.45 m (vertical) for the kinematic test.

Indoor occupants' positions are significant for smart home service systems, which usually consist of robot service(s), appliance control and other intelligent applications. In this paper, an innovative localization method is proposed for tracking humans' position in indoor environments based on passive infrared (PIR) sensors using an accessibility map and an A-star algorithm, aiming at providing intelligent services. First the accessibility map reflecting the visiting habits of the occupants is established through the integral training with indoor environments and other prior knowledge. Then the PIR sensors, which placement depends on the training results in the accessibility map, get the rough location information. For more precise positioning, the A-start algorithm is used to refine the localization, fused with the accessibility map and the PIR sensor data. Experiments were conducted in a mock apartment testbed. The ground truth data was obtained from an Opti-track system. The results demonstrate that the proposed method is able to track persons in a smart home environment and provide a solution for home robot localization.

2018-04-01

The results of a survey of multihospital pharmacy leaders are summarized, and a road map for creating organizational value with the pharmacy enterprise is presented. A survey was designed to evaluate the level of integration of pharmacy services across each system's multiple hospitals, determine the most commonly integrated services, determine whether value was quantified when services were integrated, collect common barriers for finding value through integration, and identify strategies for successfully overcoming these barriers. The comprehensive, 59-question survey was distributed electronically in September 2016 to the top pharmacy executive at approximately 160 multihospital systems located throughout the United States. Survey respondents indicated that health systems are taking a wide range of approaches to integrating services systemwide. Several themes emerged from the survey responses: (1) having a system-level pharmacy leader with solid-line reporting across the enterprise increased the likelihood of integrating pharmacy services effectively, (2) integration of pharmacy services across a multihospital system was unlikely to decrease the number of pharmacy full-time equivalents within the enterprise, and (3) significant opportunities exist for creating value for the multihospital health system with the pharmacy enterprise, particularly within 4 core areas: system-level drug formulary and clinical standardization initiatives, supply chain initiatives, electronic health record integration, and specialty and retail pharmacy services. Consistently demonstrating strong organizational leadership, entrepreneurialism, and the ability to create value for the organization will lead to the system-level pharmacy leader and the pharmacy enterprise being well-positioned to achieve positive outcomes for patients, payers, and the broader health system.

Families with a child diagnosed with autism spectrum disorder (ASD) often utilize a variety of professional services. The provision of these services has many potential benefits for families; however, these services also place demands on parents, particularly mothers, to access, navigate and participate. Little is known about how involvement with these services and service systems influences the psychological wellbeing of mothers of children diagnosed with ASD. We examined the relationship between professional services and psychological wellbeing for mothers of children diagnosed with ASD. Mothers (n = 119) of children (mean child age 10.1 years; range 2-24 years) diagnosed with ASD anonymously completed a comprehensive survey. The survey included data related to maternal psychological wellbeing, professional services received and perceptions of these services, and child, mother and household characteristics. Regression analyses revealed that maternal psychological wellbeing was positively associated with the perceived continuity of services, and negatively associated with the number of professionals involved. Child and maternal age, and household income were also statistically significant predictors of maternal psychological wellbeing. The study findings draw attention to the potentially negative impact of systems-level challenges, especially fragmentation of services, on maternal psychological wellbeing, despite positive front-line services. In particular, our data suggest that psychological wellbeing among mothers of children with ASD may vary more as a function of service system variables than practitioner-level or child-level variables. © 2016 John Wiley & Sons Ltd.

Service-oriented computing principles are used to build a distributed infrastructure of Web accessible components for accessing data and scientific applications. Our data services fall into two major categories: Archival, database-backed services based around Geographical Information System (GIS) standards from the Open Geospatial Consortium, and streaming services that can be used to filter and route real-time data sources such as Global Positioning System data streams. Execution support services include application execution management services and services for transferring remote files. These data and execution service families are bound together through metadata information and workflow services for service orchestration. Users may access the system through the QuakeSim scientific Web portal, which is built using a portlet component approach.

Incentive-Rewarding Mechanism for User-position Control in Mobile Services

NASA Astrophysics Data System (ADS)

Yoshino, Makoto; Sato, Kenichiro; Shinkuma, Ryoichi; Takahashi, Tatsuro

When the number of users in a service area increases in mobile multimedia services, no individual user can obtain satisfactory radio resources such as bandwidth and signal power because the resources are limited and shared. A solution for such a problem is user-position control. In the user-position control, the operator informs users of better communication areas (or spots) and navigates them to these positions. However, because of subjective costs caused by subjects moving from their original to a new position, they do not always attempt to move. To motivate users to contribute their resources in network services that require resource contributions for users, incentive-rewarding mechanisms have been proposed. However, there are no mechanisms that distribute rewards appropriately according to various subjective factors involving users. Furthermore, since the conventional mechanisms limit how rewards are paid, they are applicable only for the network service they targeted. In this paper, we propose a novel incentive-rewarding mechanism to solve these problems, using an external evaluator and interactive learning agents. We also investigated ways of appropriately controlling rewards based on user contributions and system service quality. We applied the proposed mechanism and reward control to the user-position control, and demonstrated its validity.

Forests are of major importance to human society, contributing several crucial ecosystem services. Biodiversity is suggested to positively influence multiple services but evidence from natural systems at scales relevant to management is scarce. Here, across a scale of 400,000 km2, we report that tree species richness in production forests shows positive to positively hump-shaped relationships with multiple ecosystem services. These include production of tree biomass, soil carbon storage, berry production and game production potential. For example, biomass production was approximately 50% greater with five than with one tree species. In addition, we show positive relationships between tree species richness and proxies for other biodiversity components. Importantly, no single tree species was able to promote all services, and some services were negatively correlated to each other. Management of production forests will therefore benefit from considering multiple tree species to sustain the full range of benefits that the society obtains from forests. PMID:23299890

VLC-based indoor location awareness using LED light and image sensors

Lee, Seok-Ju; Yoo, Jong-Ho; Jung, Sung-Yoon

2012-11-01

Recently, indoor LED lighting can be considered for constructing green infra with energy saving and additionally providing LED-IT convergence services such as visible light communication (VLC) based location awareness and navigation services. For example, in case of large complex shopping mall, location awareness to navigate the destination is very important issue. However, the conventional navigation using GPS is not working indoors. Alternative location service based on WLAN has a problem that the position accuracy is low. For example, it is difficult to estimate the height exactly. If the position error of the height is greater than the height between floors, it may cause big problem. Therefore, conventional navigation is inappropriate for indoor navigation. Alternative possible solution for indoor navigation is VLC based location awareness scheme. Because indoor LED infra will be definitely equipped for providing lighting functionality, indoor LED lighting has a possibility to provide relatively high accuracy of position estimation combined with VLC technology. In this paper, we provide a new VLC based positioning system using visible LED lights and image sensors. Our system uses location of image sensor lens and location of reception plane. By using more than two image sensor, we can determine transmitter position less than 1m position error. Through simulation, we verify the validity of the proposed VLC based new positioning system using visible LED light and image sensors.

2014-08-15

One focus of ecosystem service research is the connection between biodiversity, ecosystem services and human well-being as well as the socioeconomic influences on them. Despite existing investigations, exact impacts from the human system on the dynamics of biodiversity, ecosystem services and human well-being are still uncertain because of the insufficiency of the respective quantitative analyses. Our research aims are discerning the socioeconomic influences on biodiversity, ecosystem services and human well-being and demonstrating mutual impacts between these items. We propose a DPSIR framework coupling ecological integrity, ecosystem services as well as human well-being and suggest DPSIR indicators for the case study area Jiangsu, China. Based on available statistical and surveying data, we revealed the factors significantly impacting biodiversity, ecosystem services and human well-being in the research area through factor analysis and correlation analysis, using the 13 prefecture-level cities of Jiangsu as samples. The results show that urbanization and industrialization in the urban areas have predominant positive influences on regional biodiversity, agricultural productivity and tourism services as well as rural residents' living standards. Additionally, the knowledge, technology and finance inputs for agriculture also have generally positive impacts on these system components. Concerning regional carbon storage, non-cropland vegetation cover obviously plays a significant positive role. Contrarily, the expansion of farming land and the increase of total food production are two important negative influential factors of biodiversity, ecosystem's food provisioning service capacity, regional tourism income and the well-being of the rural population. Our study provides a promising approach based on the DPSIR model to quantitatively capture the socioeconomic influential factors of biodiversity, ecosystem services and human well-being for human-environmental systems at regional scales.

Colcy, Jean-Noel; Vanderbrouck, Laurent

1995-01-01

The EUTELTRACS two-way Mobile Satellite Messaging and Automatic Satellite Position Reporting (ASPR) service is Europe's first commercially operated Mobile Satellite Service. It was introduced by the European Telecommunications Satellite Organization (EUTELSAT) for commercial service in 1991. The system is based on a centralized network architecture organized around a single hub station operated by EUTELSAT. Initially the system was designed with a close user group architecture enabling a mobile user to communicate exclusively with its own headquarters. This paper describes the new applications (design and tests prior to their introduction into service) especially developed for the European market and particularly the Double Hop Services opening the system to authorized external entities. In addition, the European Commission (EC) pilot demonstrations in which the EUTELTRACS system is involved are described.

Indoor anti-occlusion visible light positioning systems based on particle filtering

2015-04-01

As one of the most popular categories of mobile services, a rapid growth of indoor location-based services has been witnessed over the past decades. Indoor positioning methods based on Wi-Fi, radio-frequency identification or Bluetooth are widely commercialized; however, they have disadvantages such as low accuracy or high cost. An emerging method using visible light is under research recently. The existed visible light positioning (VLP) schemes using carrier allocation, time allocation and multiple receivers all have limitations. This paper presents a novel mechanism using particle filtering in VLP system. By this method no additional devices are needed and the occlusion problem in visible light would be alleviated which will effectively enhance the flexibility for indoor positioning.

Smart Device-Supported BDS/GNSS Real-Time Kinematic Positioning for Sub-Meter-Level Accuracy in Urban Location-Based Services

2016-01-01

Using mobile smart devices to provide urban location-based services (LBS) with sub-meter-level accuracy (around 0.5 m) is a major application field for future global navigation satellite system (GNSS) development. Real-time kinematic (RTK) positioning, which is a widely used GNSS-based positioning approach, can improve the accuracy from about 10–20 m (achieved by the standard positioning services) to about 3–5 cm based on the geodetic receivers. In using the smart devices to achieve positioning with sub-meter-level accuracy, a feasible solution of combining the low-cost GNSS module and the smart device is proposed in this work and a user-side GNSS RTK positioning software was developed from scratch based on the Android platform. Its real-time positioning performance was validated by BeiDou Navigation Satellite System/Global Positioning System (BDS/GPS) combined RTK positioning under the conditions of a static and kinematic (the velocity of the rover was 50–80 km/h) mode in a real urban environment with a SAMSUNG Galaxy A7 smartphone. The results show that the fixed-rates of ambiguity resolution (the proportion of epochs of ambiguities fixed) for BDS/GPS combined RTK in the static and kinematic tests were about 97% and 90%, respectively, and the average positioning accuracies (RMS) were better than 0.15 m (horizontal) and 0.25 m (vertical) for the static test, and 0.30 m (horizontal) and 0.45 m (vertical) for the kinematic test.

2014-12-01

The use of an ecosystem service framework for natural resource management has gained increasing traction in the public sector. This is of especial interest in cities as residual ecosystems - typically located along creeks and estuaries, or remaining in scattered pockets throughout the urban area - offer some of the highest value social and economic returns per capita for the land area they occupy, yet are often impractical to manage from more traditional approaches to conservation. We posit that the well-being of humans and other species is the outcome of healthy, functioning ecosystems, and that, from a policy perspective, it is essential to consider services in this context. We arrange ecosystem services into three categories: life-enabling, life-sustaining and life-fulfilling, in a modification to the categories of the Millennium Ecosystem Assessment, and identify additional eco-services unique to urban areas. At local scale, these contribute to the well-being of city residents and positively affect quality of life, forming essential elements of urban liveability. However, dynamics of co-located built and natural environments challenge the capacity of ecosystems to function and provide their full suite of services. Using Sydney as an example, we outline a modular framework of socio-ecological systems and places to show how eco-services supporting liveability can be considered in conceptual and physical space. At a policy level, framing systems-based management objectives that protect, improve and re-discover desirable ecosystem services within the city (as opposed to further increasing the environmental footprint outside), will allow for unique, positive, socially-enabling outcomes for urban centres, in Australia, and globally.

Do they see eye to eye? Management and employee perspectives of high-performance work systems and influence processes on service quality.

Extant research on high-performance work systems (HPWSs) has primarily examined the effects of HPWSs on establishment or firm-level performance from a management perspective in manufacturing settings. The current study extends this literature by differentiating management and employee perspectives of HPWSs and examining how the two perspectives relate to employee individual performance in the service context. Data collected in three phases from multiple sources involving 292 managers, 830 employees, and 1,772 customers of 91 bank branches revealed significant differences between management and employee perspectives of HPWSs. There were also significant differences in employee perspectives of HPWSs among employees of different employment statuses and among employees of the same status. Further, employee perspective of HPWSs was positively related to individual general service performance through the mediation of employee human capital and perceived organizational support and was positively related to individual knowledge-intensive service performance through the mediation of employee human capital and psychological empowerment. At the same time, management perspective of HPWSs was related to employee human capital and both types of service performance. Finally, a branch's overall knowledge-intensive service performance was positively associated with customer overall satisfaction with the branch's service. (c) 2009 APA, all rights reserved.

NASA Astrophysics Data System (ADS)

Keyser, Donald A.

The author describes the Radiodetermination Satellite Service (RDSS). The initial phase of the RDSS provides for a unique service enabling central offices and headquarters to obtain position-location information and receive short digital messages from mobile user terminals throughout the contiguous United States, southern Canada, and northern Mexico. The system employs a spread-spectrum, CDMA modulation technique allowing multiple customers to use the system simultaneously, without preassigned coordination with fellow users. Position location is currently determined by employing an existing radio determination receiver, such as Loran-C, GPS, or Transit, in the mobile user terminal. In the early 1990s position location will be determined at a central earth station by time-differential ranging of the user terminals via two or more geostationary satellites. A brief overview of the RDSS system architecture is presented with emphasis on the user terminal and its diverse applications.

A Map/INS/Wi-Fi Integrated System for Indoor Location-Based Service Applications

Yu, Chunyang; Lan, Haiyu; Gu, Fuqiang; Yu, Fei; El-Sheimy, Naser

2017-01-01

In this research, a new Map/INS/Wi-Fi integrated system for indoor location-based service (LBS) applications based on a cascaded Particle/Kalman filter framework structure is proposed. Two-dimension indoor map information, together with measurements from an inertial measurement unit (IMU) and Received Signal Strength Indicator (RSSI) value, are integrated for estimating positioning information. The main challenge of this research is how to make effective use of various measurements that complement each other in order to obtain an accurate, continuous, and low-cost position solution without increasing the computational burden of the system. Therefore, to eliminate the cumulative drift caused by low-cost IMU sensor errors, the ubiquitous Wi-Fi signal and non-holonomic constraints are rationally used to correct the IMU-derived navigation solution through the extended Kalman Filter (EKF). Moreover, the map-aiding method and map-matching method are innovatively combined to constrain the primary Wi-Fi/IMU-derived position through an Auxiliary Value Particle Filter (AVPF). Different sources of information are incorporated through a cascaded structure EKF/AVPF filter algorithm. Indoor tests show that the proposed method can effectively reduce the accumulation of positioning errors of a stand-alone Inertial Navigation System (INS), and provide a stable, continuous and reliable indoor location service.

Adaptive Indoor Positioning Model Based on WLAN-Fingerprinting for Dynamic and Multi-Floor Environments

2017-01-01

The Global Positioning System demonstrates the significance of Location Based Services but it cannot be used indoors due to the lack of line of sight between satellites and receivers. Indoor Positioning Systems are needed to provide indoor Location Based Services. Wireless LAN fingerprints are one of the best choices for Indoor Positioning Systems because of their low cost, and high accuracy, however they have many drawbacks: creating radio maps is time consuming, the radio maps will become outdated with any environmental change, different mobile devices read the received signal strength (RSS) differently, and peoples’ presence in LOS between access points and mobile device affects the RSS. This research proposes a new Adaptive Indoor Positioning System model (called DIPS) based on: a dynamic radio map generator, RSS certainty technique and peoples’ presence effect integration for dynamic and multi-floor environments. Dynamic in our context refers to the effects of people and device heterogeneity. DIPS can achieve 98% and 92% positioning accuracy for floor and room positioning, and it achieves 1.2 m for point positioning error. RSS certainty enhanced the positioning accuracy for floor and room for different mobile devices by 11% and 9%. Then by considering the peoples’ presence effect, the error is reduced by 0.2 m. In comparison with other works, DIPS achieves better positioning without extra devices. PMID:28783047

The impact of coercion on services from the perspective of mental health care consumers with co-occurring disorders.

PubMed

Stanhope, Victoria; Marcus, Steven; Solomon, Phyllis

2009-02-01

Disengagement from services by people with serious mental illnesses continues to be a major challenge for the mental health system. Assertive community treatment combined with Housing First services is an intervention targeted toward consumers whom the system has failed to engage. The processes involved in engaging and maintaining consumers in mental health services play an important role but remain an understudied aspect of the intervention. This study examined the social interaction between consumers and case managers from the perspective of consumers. Seventy service contacts between unique consumer-case manager dyads were sampled. Consumers with co-occurring serious mental illness and substance use disorders completed interviews after each service contact. They provided information on sociodemographic characteristics, service contact characteristics, consumer-provider relationship, utilization of coercive strategies, perceived coercion, and service contact evaluation. Multivariate regression analyses examined the association of consumer-provider relationship and perceived coercion with service contact evaluation. Consumer-provider relationship was negatively associated with perceived coercion (effect size=.08). Perceived coercion was negatively associated with service contact evaluation (effect size=.34). Perceived coercion was positively associated with time in the program (effect size=.17) and negatively associated with length of the service contact (effect size=.14). Effect sizes ranging from .08 to .34 are typically considered small to medium. Findings demonstrate that for consumers, a positive response to service contacts indicated that they did not feel coerced. With consumers whose connection to services is tenuous, an immediate positive response to service contacts may be vital to maintain engagement. Research is needed to identify supportive case manager strategies that facilitate relationship building.

Combined Global Navigation Satellite Systems in the Space Service Volume

NASA Technical Reports Server (NTRS)

Force, Dale A.; Miller, James J.

2013-01-01

Besides providing position, velocity, and timing (PVT) for terrestrial users, the Global Positioning System (GPS) is also being used to provide PVT information for earth orbiting satellites. In 2006, F. H. Bauer, et. al., defined the Space Service Volume in the paper GPS in the Space Service Volume , presented at ION s 19th international Technical Meeting of the Satellite Division, and looked at GPS coverage for orbiting satellites. With GLONASS already operational, and the first satellites of the Galileo and Beidou/COMPASS constellations already in orbit, it is time to look at the use of the new Global Navigation Satellite Systems (GNSS) coming into service to provide PVT information for earth orbiting satellites. This presentation extends GPS in the Space Service Volume by examining the coverage capability of combinations of the new constellations with GPS GPS was first explored as a system for refining the position, velocity, and timing of other spacecraft equipped with GPS receivers in the early eighties. Because of this, a new GPS utility developed beyond the original purpose of providing position, velocity, and timing services for land, maritime, and aerial applications. GPS signals are now received and processed by spacecraft both above and below the GPS constellation, including signals that spill over the limb of the earth. Support of GPS space applications is now part of the system plan for GPS, and support of the Space Service Volume by other GNSS providers has been proposed to the UN International Committee on GNSS (ICG). GPS has been demonstrated to provide decimeter level position accuracy in real-time for satellites in low Earth orbit (centimeter level in non-real-time applications). GPS has been proven useful for satellites in geosynchronous orbit, and also for satellites in highly elliptical orbits. Depending on how many satellites are in view, one can keep time locked to the GNSS standard, and through that to Universal Time as long as at least one satellite is in view (the longest duration with no satellites in view is important in determining the maximum clock drift from GNSS time). Instantaneous position requires four satellites in view, but because orbital motion is predictable, it is possible to build up knowledge of the orbital position gradually through time without a need for constant four satellite coverage. However, it is desirable to have four satellite coverage when performing satellite maneuvers, since there can be significant changes in velocity, leading to large changes in orbit parameter, causing substantial divergence in position over time. The Space Service Volume has been defined as the volume between three thousand km altitude and geosynchronous altitude, and can be divided into medium orbit services between three thousand km altitude and eight thousand km altitude, and high orbit services above eight thousand km. The Terrestrial Service Volume includes the Earth s surface, the atmosphere, and space below the altitude of three thousand km. The Terrestrial Service Volume is the volume within which the GNSS systems will have very similar performance to the Earth surface, and satellites need only use the signals specified to provide terrestrial performance. Above three thousand km the use of signals passing by the Earth s limb becomes important, so it is desirable to have additional information on signal strength, phase delay, and group delay covering wider beam angles than are needed for terrestrial service (and which can be obtained by monitoring GNSS signals from the Earth s surface). This presentation will look at each of the new GNSS constellations in combination with GPS (GLONASS with GPS, Galileo with GPS, Beidou/COMPASS with GPS), and also at the combination of all four GNSS systems. The presentation will largely follow the format of GPS in the Space Service Volume , presenting data on the availability of one, two, three, or four of the various combinations of GNSS constellation satelles at approximately two thousand grid points evenly spaced and fixed in longitude and latitude, the duration of the longest single-fold outages (intervals when no satellites are available), and the duration of the longest four-fold outages (intervals when fewer than four satellites are available) at several altitudes. Following the original paper, we will use the altitudes of three hundred km (typical LEO satellite, and within the Terrestrial Service Volume), at three thousand km (border between Terrestrial Service Volume and Space Service Volume), at eight thousand km (the border between medium and high orbit service within the Space Service Volume), at fifteen thousand km (just below the GNSS constellations), at twenty five thousand km (just above the GNSS constellations), at thirty six thousand, five hundred km (limit of Space Service Volume definition, geosynchronous altitude), and at seventy thousand km (to show the potential usefulness of GNSS beyond geosynchronous altitude).

In this research, an indoor map aided INS/Wi-Fi integrated location based services (LBS) applications is proposed and implemented on smartphone platforms. Indoor map information together with measurements from an inertial measurement unit (IMU) and Received Signal Strength Indicator (RSSI) value from Wi-Fi are collected to obtain an accurate, continuous, and low-cost position solution. The main challenge of this research is to make effective use of various measurements that complement each other without increasing the computational burden of the system. The integrated system in this paper includes three modules: INS, Wi-Fi (if signal available) and indoor maps. A cascade structure Particle/Kalman filter framework is applied to combine the different modules. Firstly, INS position and Wi-Fi fingerprint position integrated through Kalman filter for estimating positioning information. Then, indoor map information is applied to correct the error of INS/Wi-Fi estimated position through particle filter. Indoor tests show that the proposed method can effectively reduce the accumulation positioning errors of stand-alone INS systems, and provide stable, continuous and reliable indoor location service.

Our emotional healthcare system is designed to cope with users' negative emotions in daily life. To make the system more intelligent, we integrated emotion recognition by facial expression to provide appropriate services based on user's current emotional state. Our emotion recognition by facial expression has confusion issue to recognize some positive, neutral and negative emotions that make the emotional healthcare system provide a relaxation service even though users don't have negative emotions. Therefore, to increase the effectiveness of the system to provide the relaxation service, we integrate stress detection from ECG signal. The stress detection might be able to address the confusion issue of emotion recognition by facial expression to provide the service. Indeed, our results show that integration of stress detection increases the effectiveness and efficiency of the emotional healthcare system to provide services.

Services used by perinatal substance-users with child welfare involvement: a descriptive study

PubMed Central

2010-01-01

Background Substance use during pregnancy often leads to involvement in the child welfare system, resulting in multiple social service systems and service providers working with families to achieve successful child welfare outcomes. The Vulnerable Infants Program of Rhode Island (VIP-RI) is a care coordination program developed to work with perinatal substance-users to optimize opportunities for reunification and promote permanency for substance-exposed infants. This paper describes services used by VIP-RI participants and child welfare outcomes. Methods Data collected during the first four years of VIP-RI were used to identify characteristics of program participants, services received, and child welfare outcomes: closed child welfare cases, reunification with biological mothers and identified infant permanent placements. Descriptive Results Medical and financial services were associated with positive child welfare outcomes. Medical services included family planning, pre- and post-natal care and HIV test counseling. Financial services included assistance with obtaining entitlement benefits and receiving tangible support such as food and clothing. Conclusions Findings from this study suggest services that address basic family needs were related to positive child welfare outcomes. The provision of basic services, such as health care and financial assistance through entitlement benefits and tangible donations, may help to establish a foundation so mothers can concentrate on recovery and parenting skills. Identification of services for perinatal substance users that are associated with more successful child welfare outcomes has implications for the child welfare system, treatment providers, courts and families.

Brookes, Gavin; Baker, Paul

2017-01-01

Objective To examine the key themes of positive and negative feedback in patients’ online feedback on NHS (National Health Service) services in England and to understand the specific issues within these themes and how they drive positive and negative evaluation. Design Computer-assisted quantitative and qualitative studies of 228 113 comments (28 971 142 words) of online feedback posted to the NHS Choices website. Comments containing the most frequent positive and negative evaluative words are qualitatively examined to determine the key drivers of positive and negative feedback. Participants Contributors posting comments about the NHS between March 2013 and September 2015. Results Overall, NHS services were evaluated positively approximately three times more often than negatively. The four key areas of focus were: treatment, communication, interpersonal skills and system/organisation. Treatment exhibited the highest proportion of positive evaluative comments (87%), followed by communication (77%), interpersonal skills (44%) and, finally, system/organisation (41%). Qualitative analysis revealed that reference to staff interpersonal skills featured prominently, even in comments relating to treatment and system/organisational issues. Positive feedback was elicited in cases of staff being caring, compassionate and knowing patients’’ names, while rudeness, apathy and not listening were frequent drivers of negative feedback. Conclusions Although technical competence constitutes an undoubtedly fundamental aspect of healthcare provision, staff members were much more likely to be evaluated both positively and negatively according to their interpersonal skills. Therefore, the findings reported in this study highlight the salience of such ‘soft’ skills to patients and emphasise the need for these to be focused upon and developed in staff training programmes, as well as ensuring that decisions around NHS funding do not result in demotivated and rushed staff. The findings also reveal a significant overlap between the four key themes in the ways that care is evaluated by patients. PMID:28450463

Experiences of working from a freestanding position as a case manager when supporting clients in the Swedish welfare system.

PubMed

Klockmo, Carolina; Marnetoft, Sven-Uno

2016-06-01

The Swedish state uses a case management function known as Personligt Ombud (PO). The role as PO differs from the traditional professional roles. It has a freestanding position in the welfare system. The aim of this study was to investigate POs' experiences of working from a freestanding position when supporting clients. Telephone interviews were conducted with 22 POs across Sweden. The interviews were recorded, transcribed, and analyzed by latent qualitative content analysis. The findings were reflected in three categories - freedom-promoted flexibility, surfing through a complex welfare system, and working for legitimacy. POs developed a holistic view to both the client as well as to the welfare system. POs experienced solely representing the client, which is a positive feature because part of the POs' role is advocating for the clients rights. The PO service differs from the PO service from other existing case management models and may need to develop strategies for decision-making and support in their own role. For example, they may use group supervision teams or 'reflective teams'. The freestanding position may also entail problems in terms of lack of legitimacy. It is important for POs to develop good platforms with the surrounding actors among others things to improve the co-ordination process. It could be interesting if the PO model would be tested in other countries that have a fragmented welfare system. The PO model may also be useful to other 'target groups' who are in need of co-ordinated rehabilitation services.

Many studies examining the food retail environment rely on geographic information system (GIS) databases for location information. The purpose of this study was to validate information provided by two GIS databases, comparing the positional accuracy of food service places within a 1 km circular buffer surrounding 34 schools in Ontario, Canada. A commercial database (InfoCanada) and an online database (Yellow Pages) provided the addresses of food service places. Actual locations were measured using a global positioning system (GPS) device. The InfoCanada and Yellow Pages GIS databases provided the locations for 973 and 675 food service places, respectively. Overall, 749 (77.1%) and 595 (88.2%) of these were located in the field. The online database had a higher proportion of food service places found in the field. The GIS locations of 25% of the food service places were located within approximately 15 m of their actual location, 50% were within 25 m, and 75% were within 50 m. This validation study provided a detailed assessment of errors in the measurement of the location of food service places in the two databases. The location information was more accurate for the online database, however, when matching criteria were more conservative, there were no observed differences in error between the databases.

Buppert, Carolyn

2005-01-01

Advanced practice nurses (APNs) have been affected positively and negatively by recent changes in the way hospitals are financed. Among these changes are the shift from cost-based reimbursement to a prospective payment system and increased opportunities for billing APN services under the physician payment system. Positive effects include the need for hospitals to decrease the length of stay of hospitalized patients, leading to jobs for APNs who make the hospital course and discharge more efficient. Negative effects include budget shortfalls that lead to layoffs. This article explains the current financial landscape, including phenomena that are impeding the billing of APN services, and recommends adjustments so that the APN role will be on firm financial footing.

At present, there is a growing interest in wireless applications, due to the fact that the technology begins to support them at reasonable costs. In this paper, we present the technology currently available for use in wireless environments, focusing on Geographic Information Systems. As an example, we present a newly developed platform for the commercialization of advanced geographical information services for use in portable devices. This platform uses available mobile telephone networks and wireless local area networks, but it is completely scalable to new technologies such as third generation mobile networks. Users access the service using a vector map player that runs on a Personal Digital Assistant with wireless access facilities and a Global Positioning System receiver. Before accessing the information, the player will request authorization from the server and download the requested map from it, if necessary. The platform also includes a system for improving Global Positioning System localization with the Real Time Differential Global Positioning System, which uses short GSM messages as the transmission medium.

Assessment Study of Using Online (CSRS) GPS-PPP Service for Mapping Applications in Egypt

2011-09-01

Many applications in navigation, land surveying, land title definitions and mapping have been made simpler and more precise due to accessibility of Global Positioning System (GPS) data, and thus the demand for using advanced GPS techniques in surveying applications has become essential. The differential technique was the only source of accurate positioning for many years, and remained in use despite of its cost. The precise point positioning (PPP) technique is a viable alternative to the differential positioning method in which a user with a single receiver can attain positioning accuracy at the centimeter or decimeter scale. In recent years, many organizations introduced online (GPS-PPP) processing services capable of determining accurate geocentric positions using GPS observations. These services provide the user with receiver coordinates in free and unlimited access formats via the internet. This paper investigates the accuracy of the Canadian Spatial Reference System (CSRS) Precise Point Positioning (PPP) (CSRS-PPP) service supervised by the Geodetic Survey Division (GSD), Canada. Single frequency static GPS observations have been collected at three points covering time spans of 60, 90 and 120 minutes. These three observed sites form baselines of 1.6, 7, and 10 km, respectively. In order to assess the CSRS-PPP accuracy, the discrepancies between the CSRS-PPP estimates and the regular differential GPS solutions were computed. The obtained results illustrate that the PPP produces a horizontal error at the scale of a few decimeters; this is accurate enough to serve many mapping applications in developing countries with a savings in both cost and experienced labor.

Thailand has recently introduced universal health care coverage for 45 million of its people, financed by general tax revenue. A capitation contract model was adopted to purchase ambulatory and hospital care, and preventive care and promotion, including reproductive health services, from public and private service providers. This paper describes the health financing system prior to universal coverage, and the extent to which Thailand has achieved reproductive health objectives prior to this reform. It then analyses the potential impact of universal coverage on reproductive health services. Whether there are positive or negative effects on reproductive health services will depend on the interaction between three key aspects: awareness of entitlement on the part of intended beneficiaries of services, the response of health care providers to capitation, and the capacity of purchasers to monitor and enforce contracts. In rural areas, the district public health system is the sole service provider and the contractual relationship requires trust and positive engagement with purchasers. We recommend an evidence-based approach to fine-tune the reproductive health services benefits package under universal coverage, as well as improved institutional capacity for purchasers and the active participation of civil society and other partners to empower beneficiaries.

Real-Time PPP Based on the Coupling Estimation of Clock Bias and Orbit Error with Broadcast Ephemeris.

Pan, Shuguo; Chen, Weirong; Jin, Xiaodong; Shi, Xiaofei; He, Fan

2015-07-22

Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations. Such an algorithm requires considerable work and hardly achieves real-time performance. However, real-time positioning service will be the dominant mode in the future. IGS is providing such an operational service (RTS) and there are also commercial systems like Trimble RTX in operation. On the basis of the regional Continuous Operational Reference System (CORS), a real-time PPP algorithm is proposed to apply the coupling estimation of clock bias and orbit error. The projection of orbit error onto the satellite-receiver range has the same effects on positioning accuracy with clock bias. Therefore, in satellite clock estimation, part of the orbit error can be absorbed by the clock bias and the effects of residual orbit error on positioning accuracy can be weakened by the evenly distributed satellite geometry. In consideration of the simple structure of pseudorange equations and the high precision of carrier-phase equations, the clock bias estimation method coupled with orbit error is also improved. Rovers obtain PPP results by receiving broadcast ephemeris and real-time satellite clock bias coupled with orbit error. By applying the proposed algorithm, the precise orbit products provided by GNSS analysis centers are rendered no longer necessary. On the basis of previous theoretical analysis, a real-time PPP system was developed. Some experiments were then designed to verify this algorithm. Experimental results show that the newly proposed approach performs better than the traditional PPP based on International GNSS Service (IGS) real-time products. The positioning accuracies of the rovers inside and outside the network are improved by 38.8% and 36.1%, respectively. The PPP convergence speeds are improved by up to 61.4% and 65.9%. The new approach can change the traditional PPP mode because of its advantages of independence, high positioning precision, and real-time performance. It could be an alternative solution for regional positioning service before global PPP service comes into operation.

Integrity Analysis of Real-Time Ppp Technique with Igs-Rts Service for Maritime Navigation

NASA Astrophysics Data System (ADS)

El-Diasty, M.

2017-10-01

Open sea and inland waterways are the most widely used mode for transporting goods worldwide. It is the International Maritime Organization (IMO) that defines the requirements for position fixing equipment for a worldwide radio-navigation system, in terms of accuracy, integrity, continuity, availability and coverage for the various phases of navigation. Satellite positioning systems can contribute to meet these requirements, as well as optimize marine transportation. Marine navigation usually consists of three major phases identified as Ocean/Coastal/Port approach/Inland waterway, in port navigation and automatic docking with alert limit ranges from 25 m to 0.25 m. GPS positioning is widely used for many applications and is currently recognized by IMO for a future maritime navigation. With the advancement in autonomous GPS positioning techniques such as Precise Point Positioning (PPP) and with the advent of new real-time GNSS correction services such as IGS-Real-Time-Service (RTS), it is necessary to investigate the integrity of the PPP-based positioning technique along with IGS-RTS service in terms of availability and reliability for safe navigation in maritime application. This paper monitors the integrity of an autonomous real-time PPP-based GPS positioning system using the IGS real-time service (RTS) for maritime applications that require minimum availability of integrity of 99.8 % to fulfil the IMO integrity standards. To examine the integrity of the real-time IGS-RTS PPP-based technique for maritime applications, kinematic data from a dual frequency GPS receiver is collected onboard a vessel and investigated with the real-time IGS-RTS PPP-based GPS positioning technique. It is shown that the availability of integrity of the real-time IGS-RTS PPP-based GPS solution is 100 % for all navigation phases and therefore fulfil the IMO integrity standards (99.8 % availability) immediately (after 1 second), after 2 minutes and after 42 minutes of convergence time for Ocean/Coastal/Port approach/Inland waterway, in port navigation and automatic docking, respectively. Moreover, the misleading information is about 2 % for all navigation phases that is considered less safe is not in immediate danger because the horizontal position error is less than the navigation alert limits.

In these days, the development of positioning technology for realizing ubiquitous environments has become one of the most important issues. The Global Positioning System (GPS) is a well-known positioning scheme, but it is not suitable for positioning in in-door/building environments because it is difficult to maintain line-of-sight condition between satellites and a GPS receiver. To such problem, various positioning methods such as RFID, WLAN, ZigBee, and Bluetooth have been developed for indoor positioning scheme. However, the majority of positioning schemes are focused on the two-dimension positioning even though three-dimension (3D) positioning information is more useful especially in indoor applications, such as smart space, U-health service, context aware service, etc. In this paper, a 3D positioning system based on mutually orthogonal nano-scale impulse radio ultra-wideband (IR-UWB) signals and cross array antenna is proposed. The proposed scheme uses nano-scale IR-UWB signals providing fine time resolution and high-resolution multiple signal specification algorithm for the time-of-arrival and the angle-of-arrival estimation. The performance is evaluated over various IEEE 802.15.4a channel models, and simulation results show the effectiveness of proposed scheme.

The diversity of mental health and substance abuse services (MHS) available to service users is seen as an indicator of the quality of the service system. In most countries MHS are provided by a mix of public, private and third sector providers. In Finland, officially, the municipalities are responsible for organizing the services needed, but the real extent and roles of private and third sector service providers are not known. Our previous study showed that the catchment area population size was strongly associated with diversity of mental health services. It is not known whether this was due to some types of services or some provider types being more sensitive to the size effect than others. The aim of this study was to investigate the association between area population size and diversity of mental health services, i.e. which types of services and which service providers' contributions are sensitive to population size. To map and classify services, we used the ESMS-R. The diversity of services was defined as the count of main types of care. Providers were classified as public, private or third sectors. The diversity of outpatient, residential and voluntary services correlated positively with catchment area population size. The strongest positive correlation between the size of population and services available was found in third sector activities followed by public providers, but no correlation was found for diversity of private services. The third sector and public corporations each provided 44 % of the service units. Third sector providers produced all self-help services and most of the day care services. Third sector and private companies provided a significant part (59 %) of the residential care service units. Significant positive correlations were found between size of catchment area population and diversity of residential, outpatient and voluntary services, indicating that these services concentrate on areas with larger population bases. The third sector seems to significantly complement the public sector in providing different services. Thus the third sector be needs to be functionally integrated with other MHS services to achieve a diversified and integrated service system.

2017-01-01

The global scale-up of Prevention of mother-to-child transmission (PMTCT) services is credited for a 52% worldwide decline in new HIV infections among children between 2001 and 2012. However, the epidemic continues to challenge maternal and paediatric HIV control efforts in Sub Saharan Africa (SSA), with repercussions on other health services beyond those directly addressing HIV and AIDS. This systematised narrative review describes the effects of PMTCT programs on other health care services and the implications for improving health systems in SSA as reported in the existing articles and scientific literature. The following objectives framed our review:To describe the effects of PMTCT on health care services and systems in SSA and assess whether the PMTCT has strengthened or weakened health systems in SSATo describe the integration of PMTCT and its extent within broader programs and health systems. Articles published in English and French over the period 1st January 2007 (the year of publication of WHO/UNICEF guidelines on global scale-up of the PMTCT) to 31 November 2016 on PMTCT programs in SSA were sought through searches of electronic databases (Medline and Google Scholar). Articles describing the impact (positive and negative effects) of PMTCT on other health care services and those describing its integration in health systems in SSA were eligible for inclusion. We assessed 6223 potential papers, reviewed 225, and included 57. The majority of selected articles offered arguments for increased health services utilisation, notably of ante-natal care, and some evidence of beneficial synergies between PMTCT programs and other health services especially maternal health care, STI prevention and early childhood immunisation. Positive and negative impact of PMTCT on other health care services and health systems are suggested in thirty-two studies while twenty-five papers recommend more integration and synergies. However, the empirical evidence of impact of PMTCT integration on broader health systems is scarce. Underlying health system challenges such as weak physical and human resource infrastructure and poor working conditions, as well as social and economic barriers to accessing health services, affect both PMTCT and the health services with which PMTCT interacts. PMTCT services increase to some extent the availability, accessibility and utilisation of antenatal care and services beyond HIV care. Vertical PMTCT programs work, when well-funded and well-managed, despite poorly functioning health systems. The beneficial synergies between PMTCT and other services are widely suggested, but there is a lack of large-scale evidence of this.

Location Based Service in Indoor Environment Using Quick Response Code Technology

2014-10-01

Today by extensive use of intelligent mobile phones, increased size of screens and enriching the mobile phones by Global Positioning System (GPS) technology use of location based services have been considered by public users more than ever.. Based on the position of users, they can receive the desired information from different LBS providers. Any LBS system generally includes five main parts: mobile devices, communication network, positioning system, service provider and data provider. By now many advances have been gained in relation to any of these parts; however the users positioning especially in indoor environments is propounded as an essential and critical issue in LBS. It is well known that GPS performs too poorly inside buildings to provide usable indoor positioning. On the other hand, current indoor positioning technologies such as using RFID or WiFi network need different hardware and software infrastructures. In this paper, we propose a new method to overcome these challenges. This method is using the Quick Response (QR) Code Technology. QR Code is a 2D encrypted barcode with a matrix structure which consists of black modules arranged in a square grid. Scanning and data retrieving process from QR Code is possible by use of different camera-enabled mobile phones only by installing the barcode reader software. This paper reviews the capabilities of QR Code technology and then discusses the advantages of using QR Code in Indoor LBS (ILBS) system in comparison to other technologies. Finally, some prospects of using QR Code are illustrated through implementation of a scenario. The most important advantages of using this new technology in ILBS are easy implementation, spending less expenses, quick data retrieval, possibility of printing the QR Code on different products and no need for complicated hardware and software infrastructures.

Abstract Objective: Telehealthcare has been used to provide healthcare service, and information technology infrastructure appears to be essential while providing telehealthcare service. Insufficiencies have been identified, such as lack of integration, need of accommodation of diverse biometric sensors, and accessing diverse networks as different houses have varying facilities, which challenge the promotion of telehealthcare. This study designs an information technology framework to strengthen telehealthcare delivery. Materials and Methods: The proposed framework consists of a system architecture design and a network transmission design. The aim of the framework is to integrate data from existing information systems, to adopt medical informatics standards, to integrate diverse biometric sensors, and to provide different data transmission networks to support a patient's house network despite the facilities. The proposed framework has been evaluated with a case study of two telehealthcare programs, with and without the adoption of the framework. Results: The proposed framework facilitates the functionality of the program and enables steady patient enrollments. The overall patient participations are increased, and the patient outcomes appear positive. The attitudes toward the service and self-improvement also are positive. Conclusions: The findings of this study add up to the construction of a telehealthcare system. Implementing the proposed framework further assists the functionality of the service and enhances the availability of the service and patient acceptances. PMID:23061641

Mayhew, Fred

2012-01-01

This article examines the nature of interorganizational relationships that are formed within a multi-tier human service delivery system. Taking into account the hierarchical structure of a statewide initiative to support early childhood education, the study investigates the differences in the relationships between organizations at the service and administrative levels of the system. Forty-nine administrative level and 146 service delivery level relationships are evaluated. Findings indicate that organizations involved in direct service delivery form more collaborative relationships. Thus, when government provides funding for human services, policymakers must seek to balance public accountability with the advantages believed to be inherent in devolved service delivery. Furthermore, practitioners who appreciate the importance and nuances of interorganizational relationships will be in a position to better manage their organizations in an environment of increased collaborative activity and joint delivery of services. Going forward, human service systems will continue to involve organizations from the public, nonprofit, and private sector. A better understanding of how these organizations work together is crucial to the effective delivery of these essential services.

2013-01-01

This paper extends the results I reported at this year's ION International Technical Meeting on multi-constellation GNSS coverage by showing how the use of multi-constellation GNSS improves Geometric Dilution of Precision (GDOP). Originally developed to provide position, navigation, and timing for terrestrial users, GPS has found increasing use for in space for precision orbit determination, precise time synchronization, real-time spacecraft navigation, and three-axis attitude control of Earth orbiting satellites. With additional Global Navigation Satellite Systems (GNSS) coming into service (GLONASS, Galileo, and Beidou) and the development of Satellite Based Augmentation Services, it is possible to obtain improved precision by using evolving multi-constellation receiver. The Space Service Volume formally defined as the volume of space between three thousand kilometers altitude and geosynchronous altitude ((is) approximately 36,500 km), with the volume below three thousand kilometers defined as the Terrestrial Service Volume (TSV). The USA has established signal requirements for the Space Service Volume (SSV) as part of the GPS Capability Development Documentation (CDD). Diplomatic efforts are underway to extend Space service Volume commitments to the other Position, Navigation, and Timing (PNT) service providers in an effort to assure that all space users will benefit from the enhanced capabilities of interoperating GNSS services in the space domain.

The literature analyzing the relationship between case management and supportive service use longitudinally among African American and Latina HIV-positive women is limited. This retrospective analysis of participant case management, supportive service, and medical charts sought to examine both descriptive and relational data on use of case management and supportive services over a 2-year period from 2002 to 2005 and to analyze moderating person- level or institution-level factors. The analyzed case management, supportive service, and medical charts revealed that participants interacted with their case manager four times and received 3.6 supportive services per month. Transportation, primary healthcare/medical specialists, and support groups were the services most used, with rates ranging from 70% to 80%. Using hierarchical linear modeling (HLM), the unconditional growth models showed that case management and supportive service use patterns remained constant over the 24-month period. Additionally, the multivariate unconditional model suggests a significant positive relationship between case management and supportive services. No moderation was indicated in the association between case management and supportive service use by person-level (e.g., mental illness, substance use) and institution-level (i.e., service delivery model) factors. Participants use supportive and case management services in a similar manner based on individual need. This synergistic relationship suggests that increases in either may result in retaining women in care. Implications for service delivery point to the need for skills building training for case managers, outreach workers, or system navigators to assist with short-term goals of establishing rapport and maintaining the client relationship, as this may lead to HIV-positive women accessing services. Additionally, outreach and engagement strategies need to be developed for those who typically underuse these services.

Diversification of health care services: the effects of ownership, environment, and strategy.

The present findings suggest that the trend toward greater diversification of hospital services is likely to be most strongly influenced by state Medicaid policies and certain hospital characteristics. Increasing Medicaid eligibility and payment levels is likely to have a positive effect on services diversification. Growth in the number of inpatient services provided and a more severe case mix are also likely to be involved with greater service diversification. Affiliation with a not-for-profit hospital system is likely to be associated with more diversified hospital services but not affiliation with an investor-owned system. There is also some indication that the overall portfolio of services which a hospital offers in regard to market share and market growth characteristics influences diversification. Specifically, a low market share portfolio is likely to be associated with less diversification. Competition is likely to be associated with more diversification; particularly for hospitals belonging to systems. The effect of competition on hospital strategy and services diversification is a particularly important area for further investigation. Increasing Medicaid payment and eligibility levels are also likely to have a positive effect on the provision of services which are usually unprofitable. Raising such levels is likely to be particularly beneficial to inner-city hospitals who are already providing a greater number of such services. However, the present data suggest that investor-owned hospitals are least likely to provide such services. Increasing Medicaid eligibility levels is also likely to be associated with fewer services for which charity care has to be provided. State regulation in the form of rate review and certificate of need is likely to be associated with more services for which hospitals provide some charity care. But such policies alone do not deal with the larger issue of how to finance care for the medically indigent. Present data suggest the charity care issue may be particularly salient in markets characterized by a relatively high degree of competition. Finally, investor-owned hospitals provide as many services involving charity care as not-for-profit system hospitals, although investor-owned system hospitals provide fewer such services than not-for-profit freestanding hospitals. Throughout, the findings indicate the importance of distinguishing between ownership and system affiliation. Previous research has failed to make a distinction between ownership form and system affiliation, thus attributing to ownership form differences which, as present findings suggest, appear to be more associated with system affiliation.(ABSTRACT TRUNCATED AT 400 WORDS)

The rapid development of multi-constellation GNSSs (Global Navigation Satellite Systems, e.g., BeiDou, Galileo, GLONASS, GPS) and the IGS (International GNSS Service) Multi-GNSS Experiment (MGEX) bring great opportunities and challenges for real-time precise positioning service. In this contribution, we present a GPS+GLONASS+BeiDou+Galileo four-system model to fully exploit the observations of all these four navigation satellite systems for real-time precise orbit determination, clock estimation and positioning. Meanwhile, an efficient multi-GNSS real-time precise positioning service system is designed and demonstrated by using the Multi-GNSS Experiment (MGEX) and International GNSS Service (IGS) data streams including stations all over the world. The addition of the BeiDou, Galileo and GLONASS systems to the standard GPS-only processing, reduces the convergence time almost by 70%, while the positioning accuracy is improved by about 25%. The successful launch of five new-generation satellites of the Chinese BeiDou Navigation Satellite System (BDS-3) marks a significant step in expanding BeiDou into a navigation system with global coverage. We present an initial characterization and performance assessment for these new-generation BeiDou-3 satellites and their signals. The characteristics of the B1C, B1I, B2a, B2b and B3I signals are evaluated in terms of observed carrier-to-noise density ratio, pseudorange multipath and noise, triple-frequency carrier phase ionosphere-free and geometry-free combination, and double-differenced carrier phase and code residuals. With respect to BeiDou-2 satellites, the analysis of code multipath shows that the elevation-dependent code biases, which have been previously identified to exist in the code observations of BeiDou-2 satellites, seem to be not obvious for all the available signals of new-generation BeiDou-3 satellites. This will significantly benefit precise applications that resolve wide-lane ambiguity based on Melbourne-Wübbena (MW) linear combinations and other applications such as single-frequency Precise Point Positioning (PPP) based on the ionosphere free code-carrier combinations. With regard to the triple-frequency carrier phase ionosphere-free and geometry-free combinations, it is found that different from BeiDou-2 and GPS Block IIF satellites, no apparent bias variations could be observed in all the new-generation BeiDou-3 satellites, which show a good consistency of the new-generation BeiDou-3 signals. The absence of such triple-frequency biases will make it convenient for the future processing of multi-frequency PPP using observations from new-generation BeiDou-3 satellites.

What does patient feedback reveal about the NHS? A mixed methods study of comments posted to the NHS Choices online service.

Brookes, Gavin; Baker, Paul

2017-04-27

To examine the key themes of positive and negative feedback in patients' online feedback on NHS (National Health Service) services in England and to understand the specific issues within these themes and how they drive positive and negative evaluation. Computer-assisted quantitative and qualitative studies of 228 113 comments (28 971 142 words) of online feedback posted to the NHS Choices website. Comments containing the most frequent positive and negative evaluative words are qualitatively examined to determine the key drivers of positive and negative feedback. Contributors posting comments about the NHS between March 2013 and September 2015. Overall, NHS services were evaluated positively approximately three times more often than negatively. The four key areas of focus were: treatment, communication, interpersonal skills and system/organisation. Treatment exhibited the highest proportion of positive evaluative comments (87%), followed by communication (77%), interpersonal skills (44%) and, finally, system/organisation (41%). Qualitative analysis revealed that reference to staff interpersonal skills featured prominently, even in comments relating to treatment and system/organisational issues. Positive feedback was elicited in cases of staff being caring, compassionate and knowing patients'' names, while rudeness, apathy and not listening were frequent drivers of negative feedback. Although technical competence constitutes an undoubtedly fundamental aspect of healthcare provision, staff members were much more likely to be evaluated both positively and negatively according to their interpersonal skills. Therefore, the findings reported in this study highlight the salience of such 'soft' skills to patients and emphasise the need for these to be focused upon and developed in staff training programmes, as well as ensuring that decisions around NHS funding do not result in demotivated and rushed staff. The findings also reveal a significant overlap between the four key themes in the ways that care is evaluated by patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Barcelo, Marc; Vicario, Jose Lopez

2017-01-01

In the last decade, the interest in Indoor Location Based Services (ILBS) has increased stimulating the development of Indoor Positioning Systems (IPS). In particular, ILBS look for positioning systems that can be applied anywhere in the world for millions of users, that is, there is a need for developing IPS for mass market applications. Those systems must provide accurate position estimations with minimum infrastructure cost and easy scalability to different environments. This survey overviews the current state of the art of IPSs and classifies them in terms of the infrastructure and methodology employed. Finally, each group is reviewed analysing its advantages and disadvantages and its applicability to mass market applications. PMID:28829386

JPL's GNSS Real-Time Earthquake and Tsunami (GREAT) Alert System

2017-04-01

We describe recent developments to the GREAT Alert natural hazard monitoring service from JPL's Global Differential GPS (GDGPS) System. GREAT Alert provides real-time, 1 Hz positioning solutions for hundreds of GNSS tracking sites, from both global and regional networks, aiming to monitor ground motion in the immediate aftermath of earthquakes. We take advantage of the centralized data processing, which is collocated with the GNSS orbit determination operations of the GDGPS System, to combine orbit determination with large-scale point-positioning in a grand estimation scheme, and as a result realize significant improvement to the positioning accuracy compared to conventional stand-alone point positioning techniques. For example, the measured median site (over all sites) real-time horizontal positioning accuracy is 2 cm 1DRMS, and the median real-time vertical accuracy is 4 cm RMS. The GREAT Alert positioning service is integrated with automated global earthquake notices from the United States Geodetic Survey (USGS) to support near-real-time calculations of co-seismic displacements with attendant formal errors based both short-term and long-term error analysis for each individual site. We will show the millimeter-level resolution of co-seismic displacement can be achieved by this system. The co-seismic displacements, in turn, are fed into a JPL geodynamics and ocean models, that estimate the Earthquake magnitude and predict the potential tsunami scale.

No Magic Bullet: A Theory-Based Meta-Analysis of Markov Transition Probabilities in Studies of Service Systems for Persons With Mental Disabilities.

Leff, Hugh Stephen; Chow, Clifton M; Graves, Stephen C

2017-03-01

A random-effects meta-analysis of studies that used Markov transition probabilities (TPs) to describe outcomes for mental health service systems of differing quality for persons with serious mental illness was implemented to improve the scientific understanding of systems performance, to use in planning simulations to project service system costs and outcomes over time, and to test a theory of how outcomes for systems varying in quality differ. Nineteen systems described in 12 studies were coded as basic (B), maintenance (M), and recovery oriented (R) on the basis of descriptions of services provided. TPs for studies were aligned with a common functional-level framework, converted to a one-month time period, synthesized, and compared with theory-based expectations. Meta-regression was employed to explore associations between TPs and characteristics of service recipients and studies. R systems performed better than M and B systems. However, M systems did not perform better than B systems. All systems showed negative as well as positive TPs. For approximately one-third of synthesized TPs, substantial interstudy heterogeneity was noted. Associations were found between TPs and service recipient and study variables Conclusions: Conceptualizing systems as B, M, and R has potential for improving scientific understanding and systems planning. R systems appear more effective than B and M systems, although there is no "magic bullet" system for all service recipients. Interstudy heterogeneity indicates need for common approaches to reporting service recipient states, time periods for TPs, service recipient attributes, and service system characteristics. TPs found should be used in Markov simulations to project system effectiveness and costs of over time.

Hospital Contributions to the Delivery of Public Health Activities in US Metropolitan Areas: National and Longitudinal Trends

Objectives. We investigated changes in hospital participation in local public health systems and the delivery of public health activities over time and assessed the relationship between hospital participation and the scope of activities available in local public health systems. Methods. We used longitudinal observations from the National Longitudinal Survey of Public Health Systems to examine how hospital contributions to the delivery of core public health activities varied in 1998, 2006, and 2012. We then used multivariate regression to assess the relationship between the level of hospital contributions and the overall availability of public health activities in the system. Results. Hospital participation in public health activities increased from 37% in 1998 to 41% in 2006 and down to 39% in 2012. Regression results indicated a positive association between hospital participation in public health activities and the total availability of public health services in the systems. Conclusions. Hospital collaboration does play an important role in the overall availability of public health services in local public health systems. Efforts to increase hospital participation in public health may have a positive impact on the scope of services provided and population health in US communities. PMID:26066929

Toward Creating Synergy Among Policy, Procedures, and Implementation of Evidence-Based Models in Child Welfare Systems: Two Case Examples.

PubMed

Chamberlain, Patricia

2017-03-01

Over the past four to five decades, multiple randomized controlled trials have verified that preventive interventions targeting key parenting skills can have far-reaching effects on improving a diverse array of child outcomes. Further, these studies have shown that parenting skills can be taught, and they are malleable. Given these advances, prevention scientists are in a position to make solid empirically based recommendations to public child service systems on using parent-mediated interventions to optimize positive outcomes for the children and families that they serve. Child welfare systems serve some of this country's most vulnerable children and families, yet they have been slow (compared to juvenile justice and mental health systems) to adopt empirically based interventions. This paper describes two child-welfare-initiated, policy-based case studies that have sought to scale-up research-based parenting skills into the routine services that caseworkers deliver to the families that they serve. In both case studies, the child welfare system leaders worked with evaluators and model developers to tailor policy, administrative, and fiscal system practices to institutionalize and sustain evidence-based practices into usual foster care services. Descriptions of the implementations, intervention models, and preliminary results are described.

Enhanced Positioning Algorithm of ARPS for Improving Accuracy and Expanding Service Coverage

PubMed Central

Lee, Kyuman; Baek, Hoki; Lim, Jaesung

2016-01-01

The airborne relay-based positioning system (ARPS), which employs the relaying of navigation signals, was proposed as an alternative positioning system. However, the ARPS has limitations, such as relatively large vertical error and service restrictions, because firstly, the user position is estimated based on airborne relays that are located in one direction, and secondly, the positioning is processed using only relayed navigation signals. In this paper, we propose an enhanced positioning algorithm to improve the performance of the ARPS. The main idea of the enhanced algorithm is the adaptable use of either virtual or direct measurements of reference stations in the calculation process based on the structural features of the ARPS. Unlike the existing two-step algorithm for airborne relay and user positioning, the enhanced algorithm is divided into two cases based on whether the required number of navigation signals for user positioning is met. In the first case, where the number of signals is greater than four, the user first estimates the positions of the airborne relays and its own initial position. Then, the user position is re-estimated by integrating a virtual measurement of a reference station that is calculated using the initial estimated user position and known reference positions. To prevent performance degradation, the re-estimation is performed after determining its requirement through comparing the expected position errors. If the navigation signals are insufficient, such as when the user is outside of airborne relay coverage, the user position is estimated by additionally using direct signal measurements of the reference stations in place of absent relayed signals. The simulation results demonstrate that a higher accuracy level can be achieved because the user position is estimated based on the measurements of airborne relays and a ground station. Furthermore, the service coverage is expanded by using direct measurements of reference stations for user positioning. PMID:27529252

The Quasi-Zenith satellites System (QZSS) is developed as an integrated satellite service system of communication, broadcasting and positioning for mobile users in specified regions of Japan from high elevation angle. Purposes of the satellite positioning system using Quasi-Zenith satellite (QZS) are to complement and augment the GPS. The national institutes concerned have been developing the positioning system using QZS since 2003 and will carry out experiments and researches in three years after the launch. In this system, National Institute of Information and Communications Technology (NICT) is mainly in charge of timing system for the satellite positioning system using QZS, such as onboard hydrogen maser atomic clock and precise time management system of the QZSS. We started to develop the engineering model of the time management system for the QZSS. The time management system for the QZSS will be used to compare time differences between QZS and earth station as well as to compare between three onboard atomic clocks. This paper introduces time management of satellite positioning system using the QZSS.

Basic elements would be: Develop new service to satisfy users' needs; orient the services to defined "market" segments; position new services or "re-position" the existing ones in order to communicate their advantages; develop a plan of marketing based on promotion, prize and place focused on the role of health professionals as the main service sellers.

Opening the Black Box: Exploring the Effect of Transformation on Online Service Delivery in Local Governments

NASA Astrophysics Data System (ADS)

van Veenstra, Anne Fleur; Zuurmond, Arre

To enhance the quality of their online service delivery, many government organizations seek to transform their organization beyond merely setting up a front office. This transformation includes elements such as the formation of service delivery chains, the adoption of a management strategy supporting process orientation and the implementation of enterprise architecture. This paper explores whether undertaking this transformation has a positive effect on the quality of online service delivery, using data gathered from seventy local governments. We found that having an externally oriented management strategy in place, adopting enterprise architecture, aligning information systems to business and sharing activities between processes and departments are positively related to the quality of online service delivery. We recommend that further research should be carried out to find out whether dimensions of organizational development too have an effect on online service delivery in the long term.

MSAT: A booster for land based mobile radiocommunication networks?

NASA Technical Reports Server (NTRS)

Boulay, Guy

1990-01-01

It is demonstrated that the foreseen phenomenal growth of mobilesat services will impact positively existing terrestrial mobile radio services. Mobilesat systems will not displace the existing terrestrial market in the near future, partly due to the high cost of their terminal units and associated airtime, but also due to some technical limitations, such as lack of spectrum efficiency and high susceptibility to shadowing. However, the ubiquity of mobilesat services will open new market to terrestrial radio technologies. The latter is expected to be the most economical way of extending locally mobilesat services to many users. Conversely, mobilesat systems will be used to extend the capabilities of terrestrial radio systems in areas where the former cannot be implemented cost effectively. It is believed that terrestrial mobile network operators using these service extension capabilities will have a competitive advantage over those who do not. Overall, it is expected that emerging mobilesat services, far from being a threat to terrestrial radio systems, will rather provide these with numerous opportunities of incrementing their base market.

The authors consider acute problems in the quality and management of medical services challenging health care systems worldwide. This actuality has motivated the representatives of the European Association for Predictive, Preventive and Personalised Medicine and European Federation of Clinical Chemistry and Laboratory Medicine to consider the efforts in promoting an integrative approach based on multidisciplinary expertise to advance health care. The current paper provides a global overview of the problems related to medical services: pandemic scenario in the progression of common chronic diseases, delayed interventional approaches of reactive medicine, poor economy of health care systems, lack of specialised educational programmes, problematic ethical aspects of treatments as well as inadequate communication among professional groups and policymakers. Further, in the form of individual paragraphs, the article presents a consolidated position of the represented European organisations. This position is focused on the patients' needs, expert recommendations for the relevant medical fields and plausible solutions which have a potential to advance health care services if the long-term strategies were to be effectively implemented as proposed here.

To evaluate the use of a national register for strategic management of dental health services for 0-17-year-old Danish children and to identify determinants for their use of the system as a strategic tool in management of the services. During the period December 1997 to January 1998, the leaders of 268 private and public dental services were mailed a self-administered postal questionnaire on their use of the dental health reporting system of the Danish National Board of Health, the so-called SCOR-system. Ninety-six percent responded. The questionnaire contained questions about the use of SCOR (dependent variable) and the following independent variables: 1) the dental service in the municipality; and 2) the leader of the dental service, including his/her assessment of and knowledge related to the SCOR-system. Information concerning other independent variables such as: 1) the population and the socio-economic, cultural and political environment of the municipality; and 2) dental morbidity was collected as antecedent data from various official sources. Seventy-seven percent of municipalities with public clinics and 68% of municipalities without public clinics used SCOR-tables for planning purposes and preventive intervention. Forty percent reported data for all age groups to the SCOR-system and 36% used non-obligatory special codes in order to monitor more specific questions. Use of SCOR data was positively associated with the dental health services being organized in public clinics, with a high number of public clinics in the municipality, and with a positive assessment among the dental leaders of the reporting system as a planning tool. Special codes for precavitated lesions and/or fissure sealants were used more frequently in municipalities where DMFS in 15-year-olds had decreased from 1995 to 1996. Otherwise no associations between dental health and use of the system could be demonstrated. SCOR is widely used as a strategic planning instrument concerning the Danish dental services for children and adolescents. The predictors associated with its use are partly structural characteristics of the municipality and its dental service and factors partly related to a leader's knowledge about and assessment of the system. These factors might be amenable to change through training of the users of the system.

Precise Positioning Method for Logistics Tracking Systems Using Personal Handy-Phone System Based on Mahalanobis Distance

NASA Astrophysics Data System (ADS)

Yokoi, Naoaki; Kawahara, Yasuhiro; Hosaka, Hiroshi; Sakata, Kenji

Focusing on the Personal Handy-phone System (PHS) positioning service used in physical distribution logistics, a positioning error offset method for improving positioning accuracy is invented. A disadvantage of PHS positioning is that measurement errors caused by the fluctuation of radio waves due to buildings around the terminal are large, ranging from several tens to several hundreds of meters. In this study, an error offset method is developed, which learns patterns of positioning results (latitude and longitude) containing errors and the highest signal strength at major logistic points in advance, and matches them with new data measured in actual distribution processes according to the Mahalanobis distance. Then the matching resolution is improved to 1/40 that of the conventional error offset method.

Woods, J

2001-01-01

The third generation cardiac institute will build on the successes of the past in structuring the service line, re-organizing to assimilate specialist interests, and re-positioning to expand cardiac services into cardiovascular services. To meet the challenges of an increasingly competitive marketplace and complex delivery system, the focus for this new model will shift away from improved structures, and toward improved processes. This shift will require a sound methodology for statistically measuring and sustaining process changes related to the optimization of cardiovascular care. In recent years, GE Medical Systems has successfully applied Six Sigma methodologies to enable cardiac centers to control key clinical and market development processes through its DMADV, DMAIC and Change Acceleration processes. Data indicates Six Sigma is having a positive impact within organizations across the United States, and when appropriately implemented, this approach can serve as a solid foundation for building the next generation cardiac institute.

Indoor high precision three-dimensional positioning system based on visible light communication using modified genetic algorithm

NASA Astrophysics Data System (ADS)

Chen, Hao; Guan, Weipeng; Li, Simin; Wu, Yuxiang

2018-04-01

To improve the precision of indoor positioning and actualize three-dimensional positioning, a reversed indoor positioning system based on visible light communication (VLC) using genetic algorithm (GA) is proposed. In order to solve the problem of interference between signal sources, CDMA modulation is used. Each light-emitting diode (LED) in the system broadcasts a unique identity (ID) code using CDMA modulation. Receiver receives mixed signal from every LED reference point, by the orthogonality of spreading code in CDMA modulation, ID information and intensity attenuation information from every LED can be obtained. According to positioning principle of received signal strength (RSS), the coordinate of the receiver can be determined. Due to system noise and imperfection of device utilized in the system, distance between receiver and transmitters will deviate from the real value resulting in positioning error. By introducing error correction factors to global parallel search of genetic algorithm, coordinates of the receiver in three-dimensional space can be determined precisely. Both simulation results and experimental results show that in practical application scenarios, the proposed positioning system can realize high precision positioning service.

In 2014, Brazil hosted one of the most popular sport competitions in the world, the FIFA World Cup. Concerned about the intense migration of tourists, the Brazilian government decided to deploy a food safety strategy based on inspection scores and a grading system applied to food services. The present study aimed to evaluate the results of the food safety strategy deployed during the 2014 FIFA World Cup in Brazil. To assess food safety, an evaluation instrument was applied twice in 1927 food service establishments from 26 cities before the start of the competition. This instrument generated a food safety score for each establishment that ranged from 0.0 (no flaws observed) to 2565.95, with four possible grades: A (0.0-13.2); B (13.3-502.6); C (502.7-1152.2); and pending (more than 1152.3). Each food service received a stamp with the grade of the second evaluation. After the end of the World Cup, a study was conducted with different groups of the public to evaluate the acceptance of the strategy. To this end, 221 consumers, 998 food service owners or managers, 150 health surveillance auditors, and 27 health surveillance coordinators were enrolled. These participants completed a survey with positive and negative responses about the inspection score system through a 5-point Likert scale. A reduction in violation scores from 393.1 to 224.4 (p < 0.001) was observed between the first and second evaluation cycles. Of the food services evaluated, 38.7% received the A stamp, 41.4% the B stamp, and 13.9% the C stamp. All positive responses on "system reliability" presented a mean of 4.0 or more, indicating that the public believed this strategy is reliable for communicating risks and promoting food safety. The strategy showed positive results regarding food safety and public acceptance. The deployed strategy promoted improvements in the food safety of food services. The implementation of a permanent policy may be well accepted by the public and may greatly contribute to a reduction in foodborne diseases (FBDs).

2017-11-01

In this paper, we discuss about the steady state behaviour of M/G/1 retrial queueing system with two phases of services and immediate feedbacks under working vacation policy where the regular busy server is affected due to the arrival of negative customers. Upon arrival if the customer finds the server busy, breakdown or on working vacation it enters an orbit; otherwise the customer enters into the service area immediately. After service completion, the customer is allowed to make finite number of immediate feedback. The feedback service also consists of two phases. At the service completion epoch of a positive customer, if the orbit is empty the server goes for a working vacation. The server works at a lower service rate during working vacation (WV) period. Using the supplementary variable technique, we found out the steady state probability generating function for the system and in orbit. System performance measures and reliability measures are discussed. Finally, some numerical examples are presented to validate the analyticalresults.

The impact of contracting-out on health system performance: a conceptual framework.

PubMed

Liu, Xingzhu; Hotchkiss, David R; Bose, Sujata

2007-07-01

Despite the increased popularity of contracting-out of health services in developing countries, its effectiveness on overall health system performance is not yet conclusive. Except for substantial evidence of contracting-out's positive effect on access to health services and some evidence on improved equity in access, there is little evidence of contracting-out's impact on quality and efficiency. Most studies on the subject evaluate specific contracting-out projects against narrowly specified project objectives, not against more broadly defined health system goals. For this reason, conclusions of positive effects pertaining to project level may not hold at system level. This paper presents a conceptual framework that is expected to facilitate comprehensive, rigorous, and standardized evaluation of contracting-out at health system level. Specifically, this framework supports: full and standardized description of contracting-out interventions, study of the determinants of effectiveness, examination of provider and purchaser responses, assessment of the impact of contracting-out on all dimensions of health system performance, and cross-project analyses.

A system able to provide position reporting and monitoring services for mobile applications represents a natural complement to the Global Positioning System (GPS) navigation system. The system architecture is defined on the basis of the communications requirements derived by user needs, allowing maximum flexibility in the use of channel capacity, and a very simple and low cost terminal. The payload is sketched, outlining the block modularity and the use of qualified hardware. The global system capacity is also derived. The spacecraft characteristics are defined on the basis of the payload requirements. A small bus optimized for Ariane IV, Delta II vehicles and based on the modularity concept is presented. The design takes full advantage of each launcher with a common basic bus or bus elements for a mass production.

Seamless positioning and navigation by using geo-referenced images and multi-sensor data.

Ubiquitous positioning is considered to be a highly demanding application for today's Location-Based Services (LBS). While satellite-based navigation has achieved great advances in the past few decades, positioning and navigation in indoor scenarios and deep urban areas has remained a challenging topic of substantial research interest. Various strategies have been adopted to fill this gap, within which vision-based methods have attracted growing attention due to the widespread use of cameras on mobile devices. However, current vision-based methods using image processing have yet to revealed their full potential for navigation applications and are insufficient in many aspects. Therefore in this paper, we present a hybrid image-based positioning system that is intended to provide seamless position solution in six degrees of freedom (6DoF) for location-based services in both outdoor and indoor environments. It mainly uses visual sensor input to match with geo-referenced images for image-based positioning resolution, and also takes advantage of multiple onboard sensors, including the built-in GPS receiver and digital compass to assist visual methods. Experiments demonstrate that such a system can greatly improve the position accuracy for areas where the GPS signal is negatively affected (such as in urban canyons), and it also provides excellent position accuracy for indoor environments.

OBJECTIVE: To explore the factors that determine whether a patient will initiate treatment within a system of health-care services, and the factors that determine whether the patient will be retained in the chosen system, in Nouna, rural Burkina Faso. METHODS: The data used were pooled from four rounds of a household survey conducted in Nouna, rural Burkina Faso. The ongoing demographic surveillance system provided a sampling framework for this survey in which 800 households were sampled using a two-stage cluster sampling procedure. More than one treatment episode was observed for a single episode of illness per patient. The multinomial logit model was used to explore the determinants of patient initiation to systems of modern, traditional and home treatment, and a binary logit model was used to explore the determinants of patient retention within the chosen health-care provider system. FINDINGS: The results suggest that the determinants of patient initiation and their subsequent retention are different. Household income, education, urban residence and expected competency of the provider are positive predictors of initiation, but not of retention, for modern health-care services. Only perceived quality of care positively predicted retention in modern health-care services. CONCLUSION: Interventions focusing on patient initiation and patient retention are likely to be different. Policies directed at enhancing initiation for modern health-care services would primarily focus on reducing financial barriers, while those directed at increasing retention would primarily focus on attributes that improve the perceived quality of care.

A Self-Organizing Spatial Clustering Approach to Support Large-Scale Network RTK Systems.

PubMed

Shen, Lili; Guo, Jiming; Wang, Lei

2018-06-06

The network real-time kinematic (RTK) technique can provide centimeter-level real time positioning solutions and play a key role in geo-spatial infrastructure. With ever-increasing popularity, network RTK systems will face issues in the support of large numbers of concurrent users. In the past, high-precision positioning services were oriented towards professionals and only supported a few concurrent users. Currently, precise positioning provides a spatial foundation for artificial intelligence (AI), and countless smart devices (autonomous cars, unmanned aerial-vehicles (UAVs), robotic equipment, etc.) require precise positioning services. Therefore, the development of approaches to support large-scale network RTK systems is urgent. In this study, we proposed a self-organizing spatial clustering (SOSC) approach which automatically clusters online users to reduce the computational load on the network RTK system server side. The experimental results indicate that both the SOSC algorithm and the grid algorithm can reduce the computational load efficiently, while the SOSC algorithm gives a more elastic and adaptive clustering solution with different datasets. The SOSC algorithm determines the cluster number and the mean distance to cluster center (MDTCC) according to the data set, while the grid approaches are all predefined. The side-effects of clustering algorithms on the user side are analyzed with real global navigation satellite system (GNSS) data sets. The experimental results indicate that 10 km can be safely used as the cluster radius threshold for the SOSC algorithm without significantly reducing the positioning precision and reliability on the user side.

Assessing the context of health care utilization in Ecuador: A spatial and multilevel analysis

PubMed Central

2010-01-01

Background There are few studies that have analyzed the context of health care utilization, particularly in Latin America. This study examines the context of utilization of health services in Ecuador; focusing on the relationship between provision of services and use of both preventive and curative services. Methods This study is cross-sectional and analyzes data from the 2004 National Demographic and Maternal & Child Health dataset. Provider variables come from the Ecuadorian System of Social Indicators (SIISE). Global Moran's I statistic is used to assess spatial autocorrelation of the provider variables. Multilevel modeling is used for the simultaneous analysis of provision of services at the province-level with use of services at the individual level. Results Spatial analysis indicates no significant differences in the density of health care providers among Ecuadorian provinces. After adjusting for various predisposing, enabling, need factors and interaction terms, density of public practice health personnel was positively associated with use of preventive care, particularly among rural households. On the other hand, density of private practice physicians was positively associated with use of curative care, particularly among urban households. Conclusions There are significant public/private, urban/rural gaps in provision of services in Ecuador; which in turn affect people's use of services. It is necessary to strengthen the public health care delivery system (which includes addressing distribution of health workers) and national health information systems. These efforts could improve access to health care, and inform the civil society and policymakers on the advances of health care reform. PMID:20222988

Our aim has been to present the functioning of orthopaedic and trauma services in the healthcare system of Serbia. In the introduction, we present geographic, demographic, political and economic elements, which define more closely the position of Serbia in the Southeastern Europe. Further, the healthcare system of Serbia, organized in four levels, is presented: self-care, primary healthcare, secondary healthcare and tertiary healthcare, as well as the schedule of 20,157 physicians engaged in healthcare. In addition, we point out numerous problems, which the system is faced with. Special attention is paid to orthopaedic and trauma services active within the system, its development, current condition and personnel education. We have concluded that, despite this being a middle-income country, the healthcare system is well developed. With 524 orthopaedic surgeons, working in 56 specialized departments, musculoskeletal diseases and trauma management are covered at all three healthcare levels. Nevertheless, the authors also underline weaknesses that are mostly of technical nature. Measures for their elimination and improvement of the entire service are also suggested.

D Modelling of AN Indoor Space Using a Rotating Stereo Frame Camera System

NASA Astrophysics Data System (ADS)

Kang, J.; Lee, I.

2016-06-01

Sophisticated indoor design and growing development in urban architecture make indoor spaces more complex. And the indoor spaces are easily connected to public transportations such as subway and train stations. These phenomena allow to transfer outdoor activities to the indoor spaces. Constant development of technology has a significant impact on people knowledge about services such as location awareness services in the indoor spaces. Thus, it is required to develop the low-cost system to create the 3D model of the indoor spaces for services based on the indoor models. In this paper, we thus introduce the rotating stereo frame camera system that has two cameras and generate the indoor 3D model using the system. First, select a test site and acquired images eight times during one day with different positions and heights of the system. Measurements were complemented by object control points obtained from a total station. As the data were obtained from the different positions and heights of the system, it was possible to make various combinations of data and choose several suitable combinations for input data. Next, we generated the 3D model of the test site using commercial software with previously chosen input data. The last part of the processes will be to evaluate the accuracy of the generated indoor model from selected input data. In summary, this paper introduces the low-cost system to acquire indoor spatial data and generate the 3D model using images acquired by the system. Through this experiments, we ensure that the introduced system is suitable for generating indoor spatial information. The proposed low-cost system will be applied to indoor services based on the indoor spatial information.

Optimation of Operation System Integration between Main and Feeder Public Transport (Case Study: Trans Jakarta-Kopaja Bus Services)

Miharja, M.; Priadi, Y. N.

2018-05-01

Promoting a better public transport is a key strategy to cope with urban transport problems which are mostly caused by a huge private vehicle usage. A better public transport service quality not only focuses on one type of public transport mode, but also concerns on inter modes service integration. Fragmented inter mode public transport service leads to a longer trip chain as well as average travel time which would result in its failure to compete with a private vehicle. This paper examines the optimation process of operation system integration between Trans Jakarta Bus as the main public transport mode and Kopaja Bus as feeder public transport service in Jakarta. Using scoring-interview method combined with standard parameters in operation system integration, this paper identifies the key factors that determine the success of the two public transport operation system integrations. The study found that some key integration parameters, such as the cancellation of “system setoran”, passenger get in-get out at official stop points, and systematic payment, positively contribute to a better service integration. However, some parameters such as fine system, time and changing point reliability, and information system reliability are among those which need improvement. These findings are very useful for the authority to set the right strategy to improve operation system integration between Trans Jakarta and Kopaja Bus services.

Recognition for positive behavior is an appropriate response of the social environment to elicit desirable external behavior among the youth. Such positive responses, rendered from various social systems, include tangible and intangible reinforcements. The following theories are used to explain the importance of recognizing positive behavior: operational conditioning, observational learning, self-determination, and humanistic perspective. In the current work, culturally and socially desirable behaviors are discussed in detail with reference to Chinese adolescents. Positive behavior recognition is especially important to adolescent development because it promotes identity formation as well as cultivates moral reasoning and social perspective thinking from various social systems. The significance of recognizing positive behavior is illustrated through the support, tutorage, invitation, and subsidy provided by Hong Kong's social systems in recognition of adolescent volunteerism. The practical implications of positive behavior recognition on youth development programs are also discussed in this work.

NAPNAP Position Statement. Position Statement on Pediatric Health Care/Medical Home: Key Issues on Care Coordination, Transitions, and Leadership.

PubMed

2016-01-01

The National Association of Pediatric Nurse Practitioners (NAPNAP) affirms that the delivery of children's health care should be family-centered, accessible, comprehensive, coordinated, culturally appropriate, compassionate, and focused on the overall well-being of children and families. All qualified pediatric health care providers should collaborate in providing health care services for children in pediatric health care/medical homes. Interventions must address the concepts of family-centered partnerships, community-based systems, and transitional care from pediatric to adult services.

Future satellite systems - Market demand assessment

NASA Technical Reports Server (NTRS)

Reiner, P. S.

1981-01-01

During 1979-80, a market study was performed regarding the future total demand for communications services, and satellite transmission service at the 4/6 GHz, 12/14 GHz, and 20/30 GHz frequencies. Included in the study were a variety of communications traffic characteristics as well as projections of the cost of C and Ku band satellite systems through the year 2000. In connection with the considered study, a total of 15 major study tasks and subtasks were undertaken and were all interrelated in various ways. The telecommunications service forecasts were concerned with a total of 21 data services, 5 voice services, and 5 video services. The traffic volumes within the U.S. for the three basic services were projected for three time periods. It is found that the fixed frequency allocation for domestic satellites combined with potential interference from adjacent satellites means a near term lack of orbital positions above the U.S.

Personalized Location-Based Recommendation Services for Tour Planning in Mobile Tourism Applications

NASA Astrophysics Data System (ADS)

Yu, Chien-Chih; Chang, Hsiao-Ping

Travel and tour planning is a process of searching, selecting, grouping and sequencing destination related products and services including attractions, accommodations, restaurants, and activities. Personalized recommendation services aim at suggesting products and services to meet users’ preferences and needs, while location-based services focus on providing information based on users’ current positions. Due to the fast growing of user needs in the mobile tourism domain, how to provide personalized location-based tour recommendation services becomes a critical research and practical issue. The objective of this paper is to propose a system architecture and design methods for facilitating the delivery of location-based recommendation services to support personalized tour planning. Based on tourists’ current location and time, as well as personal preferences and needs, various recommendations regarding sightseeing spots, hotels, restaurants, and packaged tour plans can be generated efficiently. An application prototype is also implemented to illustrate and test the system feasibility and effectiveness.

Individual Global Navigation Satellite Systems in the Space Service Volume

NASA Technical Reports Server (NTRS)

Force, Dale A.

2015-01-01

Besides providing position, navigation, and timing (PNT) to terrestrial users, GPS is currently used to provide for precision orbit determination, precise time synchronization, real-time spacecraft navigation, and three-axis control of Earth orbiting satellites. With additional Global Navigation Satellite Systems (GNSS) coming into service (GLONASS, Beidou, and Galileo), it will be possible to provide these services by using other GNSS constellations. The paper, "GPS in the Space Service Volume," presented at the ION GNSS 19th International Technical Meeting in 2006 (Ref. 1), defined the Space Service Volume, and analyzed the performance of GPS out to 70,000 km. This paper will report a similar analysis of the performance of each of the additional GNSS and compare them with GPS alone. The Space Service Volume, defined as the volume between 3,000 km altitude and geosynchronous altitude, as compared with the Terrestrial Service Volume between the surface and 3,000 km. In the Terrestrial Service Volume, GNSS performance will be similar to performance on the Earth's surface. The GPS system has established signal requirements for the Space Service Volume. A separate paper presented at the conference covers the use of multiple GNSS in the Space Service Volume.

The role of positive youth development practices in building resilience and enhancing wellbeing for at-risk youth.

Services that utilise positive youth development practices (PYD) are thought to improve the quality of the service experience leading to better outcomes for at-risk youth. This article reports on a study of 605 adolescents (aged 12-17 years) who were concurrent clients of two or more service systems (child welfare, juvenile justice, additional education, mental health). It was hypothesised that services adopting PYD approaches would be related to increases in youth resilience and better wellbeing outcomes. It was also hypothesised that risks, resilience, service experiences and wellbeing outcomes would differ by age, gender and ethnicity. Youth completed a self-report questionnaire administered individually. Path analysis was used to determine the relationship between risk, service use, resilience and a wellbeing outcome measure. MANOVA was then used to determine patterns of risk, service use, resilience and wellbeing among participants based on their demographic characteristics. Services using PYD approaches were significantly related to higher levels of youth resilience. Similarly, increased resilience was related to increased indicators of wellbeing, suggesting the mediating role of resilience between risk factors and wellbeing outcomes. When professionals adopt PYD practices and work with the positive resources around youth (their own resilience processes) interventions can make a significant contribution to wellbeing outcomes for at-risk youth.

Wan, Thomas T H; Lin, Blossom Yen-Ju; Ma, Allen

2002-04-01

This study analyzes integration mechanisms that affect system performances measured by indicators of efficiency in integrated delivery systems (IDSs) in the United States. The research question is, do integration mechanisms improve IDSs' efficiency in hospital care? American Hospital Association's Annual Survey (1998) and Dorenfest's Survey on Information Systems in Integrated Healthcare Delivery Systems (1998) were used to conduct the study, using IDS as the unit of analysis. A covariance structure equation model of the effects of system integration mechanisms on IDS performance was formulated and validated by an empirical examination of IDSs. The study sample includes 973 hospital-based integrated health care delivery systems operating in the United States, carried in the list of Dorenfests Survey on Information Systems in Integrated Health care Delivery Systems. The measurement indicators of system integration mechanisms are categorized into six related domains: informatic integration, case management, hybrid physician-hospital integration, forward integration, backward integration, and high tech medical services. The multivariate analysis reveals that integration mechanisms in system operation are positively correlated and positively affect IDSs' efficiency. The six domains of integration mechanisms account for 58.9% of the total variance in hospital performance. The service differentiation strategy such as having more high tech medical services have much stronger influences on efficiency than other integration mechanisms do. The beneficial effects of integration mechanisms have been realized in IDS performance. High efficiency in hospital care can be achieved by employing proper integration strategies in operations.

TU-FG-201-09: Predicting Accelerator Dysfunction

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

Able, C; Nguyen, C; Baydush, A

Purpose: To develop an integrated statistical process control (SPC) framework using digital performance and component data accumulated within the accelerator system that can detect dysfunction prior to unscheduled downtime. Methods: Seven digital accelerators were monitored for twelve to 18 months. The accelerators were operated in a ‘run to failure mode’ with the individual institutions determining when service would be initiated. Institutions were required to submit detailed service reports. Trajectory and text log files resulting from a robust daily VMAT QA delivery were decoded and evaluated using Individual and Moving Range (I/MR) control charts. The SPC evaluation was presented in amore » customized dashboard interface that allows the user to review 525 monitored parameters (480 MLC parameters). Chart limits were calculated using a hybrid technique that includes the standard SPC 3σ limits and an empirical factor based on the parameter/system specification. The individual (I) grand mean values and control limit ranges of the I/MR charts of all accelerators were compared using statistical (ranked analysis of variance (ANOVA)) and graphical analyses to determine consistency of operating parameters. Results: When an alarm or warning was directly connected to field service, process control charts predicted dysfunction consistently on beam generation related parameters (BGP)– RF Driver Voltage, Gun Grid Voltage, and Forward Power (W); beam uniformity parameters – angle and position steering coil currents; and Gantry position accuracy parameter: cross correlation max-value. Control charts for individual MLC – cross correlation max-value/position detected 50% to 60% of MLCs serviced prior to dysfunction or failure. In general, non-random changes were detected 5 to 80 days prior to a service intervention. The ANOVA comparison of BGP determined that each accelerator parameter operated at a distinct value. Conclusion: The SPC framework shows promise. Long term monitoring coordinated with service will be required to definitively determine the effectiveness of the model.

Recently, a number of Global Health Initiatives (GHI) have been created to address single disease issues in low-income countries, such as poliomyelitis, trachoma, neonatal tetanus, etc.. Empirical evidence on the effects of such GHIs on local health systems remains scarce. This paper explores positive and negative effects of the Integrated Neglected Tropical Disease (NTD) Control Initiative, consisting in mass preventive chemotherapy for five targeted NTDs, on Mali's health system where it was first implemented in 2007. Campaign processes and interactions with the health system were assessed through participant observation in two rural districts (8 health centres each). Information was complemented by interviews with key informants, website search and literature review. Preliminary results were validated during feedback sessions with Malian authorities from national, regional and district levels. We present positive and negative effects of the NTD campaign on the health system using the WHO framework of analysis based on six interrelated elements: health service delivery, health workforce, health information system, drug procurement system, financing and governance. At point of delivery, campaign-related workload severely interfered with routine care delivery which was cut down or totally interrupted during the campaign, as nurses were absent from their health centre for campaign-related activities. Only 2 of the 16 health centres, characterized by a qualified, stable and motivated workforce, were able to keep routine services running and to use the campaign as an opportunity for quality improvement. Increased workload was compensated by allowances, which significantly improved staff income, but also contributed to divert attention away from core routine activities. While the campaign increased the availability of NTD drugs at country level, parallel systems for drug supply and evaluation requested extra efforts burdening local health systems. The campaign budget barely financed institutional strengthening. Finally, though the initiative rested at least partially on national structures, pressures to absorb donated drugs and reach short-term coverage results contributed to distract energies away from other priorities, including overall health systems strengthening. Our study indicates that positive synergies between disease specific interventions and nontargeted health services are more likely to occur in robust health services and systems. Disease-specific interventions implemented as parallel activities in fragile health services may further weaken their responsiveness to community needs, especially when several GHIs operate simultaneously. Health system strengthening will not result from the sum of selective global interventions but requires a comprehensive approach.

Service area size assessment for evaluating the spatial scale of solid waste recovery chains: A territorial perspective.

2017-06-01

Waste recovery is an integrated part of municipal solid waste management systems but its strategic planning is still challenging. In particular, the service area size of facilities is a sensitive issue since its calculation depends on various factors related to treatment technologies (output products) and territorial features (sources waste production and location). This work presents a systemic approach for the estimation of a chain's service area size, based on a balance between costs and recovery profits. The model assigns a recovery performance value to each source, which can be positive, neutral or negative. If it is positive, the source should be included in the facility's service area. Applied to the case of Montreal for food waste recovery by anaerobic digestion, the approach showed that at most 23 out of the 30 districts should be included in the service area, depending on the indicator, which represents around 127,000 t of waste recovered/year. Due to the systemic approach, these districts were not necessarily the closest to the facility. Moreover, for the Montreal case, changing the facility's location did not have a great influence on the optimal service area size, showing that the distance to the facility was not a decisive factor at this scale. However, replacing anaerobic digestion by a composting plant reduced the break-even transport distances and, thus, the number of sources worth collecting (around 68,500 t/year). In this way, the methodology, applied to different management strategies, gave a sense of the spatial dynamics involved in the recovery chain's design. The map of optimal supply obtained could be used to further analyse the feasibility of multi-site and/or multi-technology systems for the territory considered. Copyright © 2017 Elsevier Ltd.

Evidence on optimal methods for providing STI test results is lacking. We evaluated an online results service, developed as part of an eSexual Health Clinic (eSHC). We evaluated the online results service using a mixed-methods approach within large exploratory studies of the eSHC. Participants were chlamydia- positive and negative users of online postal self-sampling services in six National Chlamydia Screening Programme (NCSP) areas and chlamydia-positive patients from two genitourinary medicine (GUM) clinics between 21 July 2014 and 13 March 2015. Participants received a discreetly worded National Health Service 'NHS no-reply' text message (SMS) informing them that their test results were ready and providing a weblink to a secure website. Participants logged in with their date of birth and mobile telephone or clinic number. Chlamydia-positive patients were offered online management. All interactions with the eSHC system were automatically logged and their timing recorded. Post-treatment, a service evaluation survey (n=152) and qualitative interviews (n=36) were conducted by telephone. Chlamydia-negative patients were offered a short online survey (n=274). Data were integrated. 92% (134/146) of NCSP chlamydia-positive patients, 82% (161/197) of GUM chlamydia-positive patients and 89% (1776/1997) of NCSP chlamydia-negative participants accessed test results within 7 days. 91% of chlamydia-positive patients were happy with the results service; 64% of those who had tested previously found the results service better or much better than previous experiences. 90% of chlamydia-negative survey participants agreed they would be happy to receive results this way in the future. Interviewees described accessing results with ease and appreciated the privacy and control the two-step process gave them. A discreet SMS to alert users/patients that results are available, followed by provision of results via a secure website, was highly acceptable, irrespective of test result and testing history. The eSHC results service afforded users privacy and control over when they viewed results without compromising access. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The European Space Agency (ESA), the European Community (EC), and the European Organisation for the Safety of Air Navigation (Eurocontrol) are contributing to the development of a Global positioning and Navigation Satellite System, known as GNSS. The development programme is carried out in two main steps:• GNSS-1: the first-generation system, based on signals received from the GPS (USA) and GLONASS (Russia) constellations, and augmentation systems like EGNOS (European Geostationary Navigation Overlay Service)• GNSS-2: the second-generation system, that will achieve the ultimate objective of European sovereignty for position determination, navigation and time dissemination. This system, named Galileo, comprises a global space and ground control infrastructure.The Galileo navigation signal will be used in the frame of safety-critical transport applications, thus it is necessary to assess the space safety assurance activity against the civil safety regulations and safety management system.. RTCA DO-254 and IEC 61508 standards, considered as part of best practice engineering references, for the development of safety- related systems in most applications, were selected during phases B2 and C0 of the Galileo project for this purpose.

Associations between the peer support relationship, service satisfaction and recovery-oriented outcomes: a correlational study.

PubMed

Thomas, Elizabeth C; Salzer, Mark S

2017-12-18

The working alliance between non-peer providers and mental health consumers is associated with positive outcomes. It is hypothesized that this factor, in addition to other active support elements, is also positively related to peer support service outcomes. This study evaluates correlates of the peer-to-peer relationship and its unique association with service satisfaction and recovery-oriented outcomes. Participants were 46 adults with serious mental illnesses taking part in a peer-brokered self-directed care intervention. Pearson correlation analyses examined associations among peer relationship factors, services-related variables and recovery-oriented outcomes (i.e. empowerment, recovery and quality of life). Hierarchical multiple regression analyses evaluated associations between relationship factors and outcomes over time, controlling for other possible intervention effects. The peer relationship was not related to number of contacts. There were robust associations between the peer relationship and service satisfaction and some recovery-oriented outcomes at 24-months, but not at 12-months. These associations were not explained by other possible intervention effects. This study contributes to a better understanding of the positive, unique association between the peer-to-peer relationship and outcomes, similar to what is found in non-peer-delivered interventions. Implications for program administrators and policymakers seeking to integrate peer specialists into mental health service systems are discussed.

Chon, Yongho

2013-01-01

One of the main reasons for reforming long-term care systems is a deficient existing service infrastructure for the elderly. This article provides an overview of why and how the Korean government expanded long-term care infrastructure through the introduction of a new compulsory insurance system, with a particular focus on the market-friendly policies used to expand the infrastructure. Then, the positive results of the expansion of the long-term care infrastructure and the challenges that have emerged are examined. Finally, it is argued that the Korean government should actively implement a range of practical policies and interventions within the new system.

Set up to fail? Consumer participation in the mental health service system.

PubMed

Stewart, Sarah; Watson, Sandy; Montague, Roslyn; Stevenson, Caroline

2008-10-01

The aim of this paper is to present the findings of a survey of consumers of mental health services who are working (in either paid or unpaid positions) in NSW Health and in the Non Government Organisation sector in NSW. A survey was distributed through the NSW Consumer Advisory Group newsletter to elicit the roles and assess the training needs of consumer employees, as well as those who were working in voluntary capacities as consumer representatives, within the mental health system in NSW. Many mental health consumers have been placed in the untenable position of being engaged in representation and/or advocacy roles with unclear job descriptions and no training. The majority of consumers want a code of ethics and performance standards for consumer workers. The rhetoric of consumer participation is not matched by effective and timely strategies that ensure that consumer involvement is underpinned by relevant training and supportive infrastructure. The goal of meaningful consumer participation in mental health services, as outlined in policy, is yet to be achieved.

A study of HIV positive undocumented African migrants' access to health services in the UK.

Newly immigrated persons, whatever their origin, tend to fall in the lower socioeconomic levels. In fact, failure of an asylum application renders one destitute in a large proportion of cases, often resulting in a profound lack of access to basic necessities. With over a third of HIV positive failed asylum seekers reporting no income, and the remainder reporting highly limited resources, poverty is a reality for the vast majority. The purpose of the study was to determine the basic social processes that guide HIV positive undocumented migrant's efforts to gain health services in the UK. The study used the Grounded Theory Approach. Theoretical saturation occurred after 16 participants were included in the study. The data included reflections of the prominent factors related to the establishment of a safe and productive life and the ability of individuals to remain within the UK. The data reflected heavily upon the ability of migrants to enter the medical care system during their asylum period, and on an emerging pattern of service denial after loss on immigration appeal. The findings of this study are notable in that they have demonstrated sequence of events along a timeline related to the interaction between the asylum process and access to health-related services. The results reflect that African migrants maintain a degree of formal access to health services during the period that they possess legal access to services and informal access after the failure of their asylum claim. The purpose of this paper is to examine the basic social processes that characterize efforts to gain access to health services among HIV positive undocumented African migrants to the UK. The most recent estimates indicate that there are a total of 618,000 migrants who lack legal status within the UK. Other studies have placed the number of undocumented migrants within the UK in the range of 525,000-950,000. More than 442,000 are thought to dwell in the London metropolitan area. Even in cases where African migrants enter the UK legally, they often face considerable difficulty in their quest to gain legal employment due to barriers inherent to the system that grants work permits. With over a third of HIV positive failed asylum seekers reporting no income, and the remainder reporting highly limited resources, poverty is a reality for the vast majority.

GAUSS Market Analysis for Integrated Satellite Communication and Navigation Location Based services

NASA Astrophysics Data System (ADS)

Di Fazio, Antonella; Dricot, Fabienne; Tata, Francesco

2003-07-01

The demand for mobile information services coupled with positioning technologies for delivering value- added services that depend on a user's location has rapidly increased during last years. In particular, services and applications related with improved mobility safety and transport efficiency look very attractive.Solutions for location services vary in respect of positioning accuracy and the technical infrastructure required, and the associated investment in terminals and networks. From the analysis of the state-of-the art, it comes that various technologies are currently available on the European market, while mobile industry is gearing up to launch a wide variety of location services like tracking, alarming and locating.Nevertheless, when addressing safety of life as well as security applications, severe hurdles have to be posed in the light of existing technologies. Existing navigation (e.g. GPS) and communication systems are not able to completely satisfy the needs and requirements of safety-of-life-critical applications. As a matter of fact, the GPS system's main weaknesses today is its lack of integrity, which means its inability to warn users of a malfunction in a reasonable time, while the other positioning techniques do not provide satisfactory accuracy as well, and terrestrial communication networks are not capable to cope with stringent requirement in terms of service reliability and coverage.In this context, GAUSS proposes an innovative satellite-based solution using novel technology and effective tools for addressing mobility challenges in a cost efficient manner, improving safety and effectiveness.GAUSS (Galileo And UMTS Synergetic System) is a Research and Technological Development project co- funded by European Commission, within the frame of the 5th IST Programme. The project lasted two years, and it was successfully completed in November 2002. GAUSS key concept is the integration of Satellite Navigation GNSS and UMTS communication technology, to provide high quality location based services (tracking, tracing, alarming, messaging, group broadcasting, fleet management information) oriented to mass and business markets transport & mobility management. The GAUSS rationales for the proposed solution rely on the consideration that the existing and available systems are not capable to completely fulfil stringent requirements for the navigation and communication capabilities, in terms of integrity/continuity positioning and guarantee of performances, as those coming from classes of users in the inter-modality and specific personal info-mobility sectors.For the navigation functions, the use of GALILEO will ensure a guaranteed quality of service and adequate performances, in terms of accuracy and integrity, as required for safety and working condition improvements (such as restricted waterways - ports, coasts, rivers - and hazardous goods transportation). Furthermore, it also will enable to cope with liability and certification requirements that are needed for responsibility issues, in case of damages or accidents.From the communication viewpoint, the challenges reside on the usage of the UMTS. This enables to fit GAUSS into an open market place: avoiding proliferation of standards and adoption of open interfaces to be defined by the business interest. Furthermore, the GAUSS solution fully exploits the advantages coming from the usage of the satellite of offering solutions for effectively complement terrestrial based systems (fast and large coverage, economically viable set-up cost, efficient provisioning of broadcasting and multicasting features, gap filler capability).A comprehensive market analysis was carried out in the frame of the project, aimed at investigating the techno-economical viability for a possible commercial introduction of the proposed solution.This paper presents the output of the performed studies, resulting in a realistic picture of the GAUSS market:§ Identification of potential actors/players (operators, manufacturers, professional and mass market users, service providers, authorities, etc.)§ Competitive analysis§ Market size and segmentation, and GAUSS position in the market§ Business models§ Business plan and cost/benefit ratio§ Identification of market opportunities for services and applications, in view of the future GALILEO and S-UMTS.

Local, regional and national interoperability in hospital-level systems architecture.

2007-01-01

Interoperability of applications in health care is faced with various needs by patients, health professionals, organizations and policy makers. A combination of existing and new applications is a necessity. Hospitals are in a position to drive many integration solutions, but need approaches which combine local, regional and national requirements and initiatives with open standards to support flexible processes and applications on a local hospital level. We discuss systems architecture of hospitals in relation to various processes and applications, and highlight current challenges and prospects using a service-oriented architecture approach. We also illustrate these aspects with examples from Finnish hospitals. A set of main services and elements of service-oriented architectures for health care facilities are identified, with medium-term focus which acknowledges existing systems as a core part of service-oriented solutions. The services and elements are grouped according to functional and interoperability cohesion. A transition towards service-oriented architecture in health care must acknowledge existing health information systems and promote the specification of central processes and software services locally and across organizations. Software industry best practices such as SOA must be combined with health care knowledge to respond to central challenges such as continuous change in health care. A service-oriented approach cannot entirely rely on common standards and frameworks but it must be locally adapted and complemented.

In the last few decades, there has been a restructuring of the psychiatric services in many countries. The complexity of these systems may represent a challenge to patients that suffer from serious psychiatric disorders. We examined whether local integration of inpatient and outpatient services in contrast to centralized institutions strengthened continuity of care. Two different service-systems were compared. Service-utilization over a 4-year period for 690 inpatients was extracted from the patient registries. The results were controlled for demographic variables, model of service-system, central inpatient admission or local inpatient admission, diagnoses, and duration of inpatient stays. The majority of inpatients in the area with local integration of inpatient and outpatient services used both types of care. In the area that did not have beds locally, many patients that had been hospitalized did not receive outpatient follow-up. Predictors of inpatients' use of outpatient psychiatric care were: Model of service-system (centralized vs decentralized), a diagnosis of affective disorder, central inpatient admission only, and duration of inpatient stays. Psychiatric centers with local inpatient units may positively affect continuity of care for patients with severe psychiatric disorders, probably because of a high functional integration of inpatient and outpatient care.

There is no consensus in the literature regarding the impact of false positive newborn screening results on early health care utilization patterns. We evaluated the impact of false positive newborn screening results for medium-chain acyl-CoA dehydrogenase deficiency (MCADD) in a cohort of Ontario infants. The cohort included all children who received newborn screening in Ontario between April 1, 2006 and March 31, 2010. Newborn screening and diagnostic confirmation results were linked to province-wide health care administrative datasets covering physician visits, emergency department visits, and inpatient hospitalizations, to determine health service utilization from April 1, 2006 through March 31, 2012. Incidence rate ratios (IRRs) were used to compare those with false positive results for MCADD to those with negative newborn screening results, stratified by age at service use. We identified 43 infants with a false positive newborn screening result for MCADD during the study period. These infants experienced significantly higher rates of physician visits (IRR: 1.42) and hospitalizations (IRR: 2.32) in the first year of life relative to a screen negative cohort in adjusted analyses. Differences in health services use were not observed after the first year of life. The higher use of some health services among false positive infants during the first year of life may be explained by a psychosocial impact of false positive results on parental perceptions of infant health, and/or by differences in underlying health status. Understanding the impact of false positive newborn screening results can help to inform newborn screening programs in designing support and education for families. This is particularly important as additional disorders are added to expanded screening panels, yielding important clinical benefits for affected children but also a higher frequency of false positive findings.

Strong health systems are said to be paramount to achieving effective and equitable health care. The World Health Organization has been advocating for using system-wide approaches such as 'systems thinking' to guide intervention design and evaluation. In this paper we report the system-wide effects of a complex health system intervention in Zambia known as Better Health Outcome through Mentorship and Assessment (BHOMA) that aimed to improve service quality. We conducted a qualitative study in three target districts. We used a systems thinking conceptual framework to guide the analysis focusing on intended and unintended consequences of the intervention. NVivo version 10 was used for data analysis. The addressed community responded positively to the BHOMA intervention. The indications were that in the short term there was increased demand for services but the health worker capacity was not severely affected. This means that the prediction that service demand would increase with implementation of BHOMA was correct and the workload also increased, but the help of clinic lay supporters meant that some of the work of clinicians was transferred to these lay workers. However, from a systems perspective, unintended consequences also occurred during the implementation of the BHOMA. We applied an innovative approach to evaluate a complex intervention in low-income settings, exploring empirically how systems thinking can be applied in the context of health system strengthening. Although the intervention had some positive outcomes by employing system-wide approaches, we also noted unintended consequences. © 2015 The Authors.

Treatment effectiveness holds considerable importance in the association between service quality and satisfaction in medical service studies. While complementary and alternative medicine (CAM) use grows more prominent, comprehensive evaluations of the quality of medical service at CAM-oriented hospitals are scarce. This study assesses the quality of medical services provided at a CAM-oriented hospital of Korean medicine using the service encounter system approach and analyzes the influence of treatment effectiveness on patient loyalty. A survey study using one-on-one interviews was conducted using a cross-sectional design in outpatients visiting one of fifteen Korean medicine facilities located throughout Korea. A total of 880 surveys were completed from June to July, 2014, and 728 surveys were included in the final analysis after excluding incomplete or incorrect questionnaires. The reliability and validity of the surveys was confirmed using Cronbach's alpha coefficient and confirmatory factor analysis, and a structural equation modeling analysis was performed to verify causality and association between factors (quality of medical service, treatment effectiveness, patient satisfaction, and intent to revisit). The measured factors of physician performance and quality of service procedures had a positive effect on treatment effectiveness. The impression of the facilities and environment directly impacted satisfaction rates for interpersonal-based medical service encounters, while treatment effectiveness positively affected satisfaction regarding quality of medical service. However, treatment effectiveness had a more significant effect on satisfaction compared to facilities and environment, and it indirectly affected satisfaction and directly influenced intent to revisit. Treatment effectiveness and satisfaction both positively influenced intent to revisit. The importance of treatment effectiveness should be recognized when examining quality of medical services, and we hope that these findings may contribute to future studies.

The study and realization of BDS un-differenced network-RTK based on raw observations

2017-06-01

A BeiDou Navigation Satellite System (BDS) Un-Differenced (UD) Network Real Time Kinematic (URTK) positioning algorithm, which is based on raw observations, is developed in this study. Given an integer ambiguity datum, the UD integer ambiguity can be recovered from Double-Differenced (DD) integer ambiguities, thus the UD observation corrections can be calculated and interpolated for the rover station to achieve the fast positioning. As this URTK model uses raw observations instead of the ionospheric-free combinations, it is applicable for both dual- and single-frequency users to realize the URTK service. The algorithm was validated with the experimental BDS data collected at four regional stations from day of year 080 to 083 in 2016. The achieved results confirmed the high efficiency of the proposed URTK for providing the rover users a rapid and precise positioning service compared to the standard NRTK. In our test, the BDS URTK can provide a positioning service with cm level accuracy, i.e., 1 cm in the horizontal components, and 2-3 cm in the vertical component. Within the regional network, the mean convergence time for the users to fix the UD ambiguities is 2.7 s for the dual-frequency observations and of 6.3 s for the single-frequency observations after the DD ambiguity resolution. Furthermore, due to the feature of realizing URTK technology under the UD processing mode, it is possible to integrate the global Precise Point Positioning (PPP) and the local NRTK into a seamless positioning service.

Financial performance and managed care trends of health centers.

Data were analyzed from the 1998-2004 Uniform Data System (UDS) to identify trends and predictors of financial performance (costs, productivity, and overall financial health) for health centers (HCs). Several differences were noted regarding revenues, self-sufficiency, service offerings, and urban/rural setting. Urban centers with larger numbers of clients, centers that treated high numbers of patients with chronic diseases, and centers with large numbers of prenatal care users were the most fiscally sound. Positive financial performance can be targeted through strategies that generate positive revenue, strive to decrease costs, and target services that are in demand.

The Goddard Space Flight Center is currently developing advanced spacecraft systems to provide autonomous navigation and control of formation flyers. This paper discusses autonomous relative navigation performance for a formation of four eccentric, medium-altitude Earth-orbiting satellites using Global Positioning System (GPS) Standard Positioning Service (SPS) and "GPS-like " intersatellite measurements. The performance of several candidate relative navigation approaches is evaluated. These analyses indicate that an autonomous relative navigation position accuracy of 1meter root-mean-square can be achieved by differencing high-accuracy filtered solutions if only measurements from common GPS space vehicles are used in the independently estimated solutions.

In an effort to improve natural hazard monitoring, JPL has invested in updating and enlarging its global real-time GNSS tracking network, and has launched a unique service - real-time precise positioning for natural hazard monitoring, entitled GREAT Alert (GNSS Real-Time Earthquake and Tsunami Alert). GREAT Alert leverages the full technological and operational capability of the JPL's Global Differential GPS System [www.gdgps.net] to offer owners of real-time dual-frequency GNSS receivers: Sub-5 cm (3D RMS) real-time, absolute positioning in ITRF08, regardless of location Under 5 seconds turnaround time Full covariance information Estimates of ancillary parameters (such as troposphere) optionally provided This service enables GNSS networks operators to instantly have access to the most accurate and reliable real-time positioning solutions for their sites, and also to the hundreds of participating sites globally, assuring inter-consistency and uniformity across all solutions. Local authorities with limited technical and financial resources can now access to the best technology, and share environmental data to the benefit of the entire pacific region. We will describe the specialized precise point positioning techniques employed by the GREAT Alert service optimized for natural hazard monitoring, and in particular Earthquake monitoring. We address three fundamental aspects of these applications: 1) small and infrequent motion, 2) the availability of data at a central location, and 3) the need for refined solutions at several time scales

Global Navigation Satellite Systems (GNSS) have revolutionized the science and engineering of positioning, timing and navigation and have become an indispensable means to rapidly obtain precise positioning-related information, profoundly affecting our daily life and infrastructure. With GNSS, the position of an object, either stationary or moving, can be determined anywhere, anytime and under any weather condition. In addition to providing a positioning and timing information service, GNSS are now also used to reconstruct physical properties of media through which GNSS signals travel. The utilization of additional GNSS systems such as the European Galileo and the Chinese Beidou (both expected to complete their final global constellations in 2020) will contribute to positioning/navigation science and engineering, provide more industrial opportunities and surely open more challenges.

Decentralisation of general management within the New Zealand health system.

1994-11-01

The radical organisation changes implemented in the New Zealand health system in recent years are discussed and analysed in this study which is based upon a review of documents and interviews with general managers of area health boards. Service management, which involves the decentralisation of general management to programme or product groupings (medicine, child health etc) has been widely implemented in almost all boards completely replacing the traditional disciplinary hierarchies. It is also leading to a population-rather than an institutional-based system of management. General managers report positively on the achievements of service management including greater accountability and commitment of clinical staff, innovation and team building, improved performance and service quality, the integration of hospital and community-based care and a customer rather than an occupational orientation. There is an increasing trend towards the recognition of primary health care as a key service entity.

2011-01-01

The separation of revenue and expenditure budgets (SREB) is a new financial budgetary system that is being implemented in community health services (CHS) institutions in some areas in China. Through literature review, it was found that, derived from the traditional separation of revenue and expenditure budgets (TSREB) implemented in administrative public services units, SREB and TSREB have something in common and yet many more differences. On the basis of some quantitative and qualitative data that were collected by field survey, it was also found that implementation of SREB in CHS institutions brings positive outcomes in terms of the quantity, quality and efficiency of services; residents' satisfaction; and the behavior of CHS institutions. The conclusion can be suggested that SREB, as a system having impact upon the incentives facing CHS institutions and the nature of governmental responsibility for developing CHS in China, will promote CHS institutions to fulfill basic service functions if implemented well. Therefore, it is a system that is worth further development and evaluation. Copyright © 2011 John Wiley & Sons, Ltd.

Listening to the customer: implementing a patient satisfaction measurement system.

PubMed

Cohen, L; Delaney, P; Boston, P

1994-01-01

Patient satisfaction is an important issue in positioning ambulatory medical services. An effective patient satisfaction measurement program not only helps hospital managers improve the quality of clinical and administrative activities, but also helps the hospital remain viable in increasingly competitive markets. A method for the design and measurement of patient satisfaction with outpatient Endoscopy Lab services is described in this article. The survey focuses on the sequence of events experienced by the patient. Outcome measures of primary interest include global patient satisfaction and the likelihood of using the service again if given a choice. Analysis of patient responses shows that global satisfaction with the outpatient experience is positively associated with service return intention. Additional analysis shows that facility cleanliness, privacy and nurse attention are most strongly associated with global patient satisfaction. Results underscore the importance of various service attributes on patient satisfaction and return intention and of the need to further expand the uses of patient satisfaction measurement in the outpatient Endoscopy Lab.

An approach for real-time fast point positioning of the BeiDou Navigation Satellite System using augmentation information

2018-07-01

This study proposes an approach to facilitate real-time fast point positioning of the BeiDou Navigation Satellite System (BDS) based on regional augmentation information. We term this as the precise positioning based on augmentation information (BPP) approach. The coordinates of the reference stations were highly constrained to extract the augmentation information, which contained not only the satellite orbit clock error correlated with the satellite running state, but also included the atmosphere error and unmodeled error, which are correlated with the spatial and temporal states. Based on these mixed augmentation corrections, a precise point positioning (PPP) model could be used for the coordinates estimation of the user stations, and the float ambiguity could be easily fixed for the single-difference between satellites. Thus, this technique provided a quick and high-precision positioning service. Three different datasets with small, medium, and large baselines (0.6 km, 30 km and 136 km) were used to validate the feasibility and effectiveness of the proposed BPP method. The validations showed that using the BPP model, 1–2 cm positioning service can be provided in a 100 km wide area after just 2 s of initialization. Thus, as the proposed approach not only capitalized on both PPP and RTK but also provided consistent application, it can be used for area augmentation positioning.

In this study, a unified model for BeiDou Navigation Satellite System (BDS) wide area and local area augmentation positioning based on raw observations has been proposed. Applying this model, both the Real-Time Kinematic (RTK) and Precise Point Positioning (PPP) service can be realized by performing different corrections at the user end. This algorithm was assessed and validated with the BDS data collected at four regional stations from Day of Year (DOY) 080 to 083 of 2016. When the users are located within the local reference network, the fast and high precision RTK service can be achieved using the regional observation corrections, revealing a convergence time of about several seconds and a precision of about 2-3 cm. For the users out of the regional reference network, the global broadcast State-Space Represented (SSR) corrections can be utilized to realize the global PPP service which shows a convergence time of about 25 min for achieving an accuracy of 10 cm. With this unified model, it can not only integrate the Network RTK (NRTK) and PPP into a seamless positioning service, but also recover the ionosphere Vertical Total Electronic Content (VTEC) and Differential Code Bias (DCB) values that are useful for the ionosphere monitoring and modeling.

This paper presents a study of positioning system that provides advanced information services based on Wi-Fi and Bluetooth Low Energy (BLE) technologies. It uses Wi-Fi for rough positioning and BLE for fine positioning. It is designed for use in public transportation system stations and terminals where the conditions are "hostile" or unfavourable due to signal noise produced by the continuous movement of passengers and buses, data collection conducted in the constant presence thereof, multipath fading, non-line of sight (NLOS) conditions, the fact that part of the wireless communication infrastructure has already been deployed and positioned in a way that may not be optimal for positioning purposes, variable humidity conditions, etc. The ultimate goal is to provide a service that may be used to assist people with special needs. We present experimental results based on scene analysis; the main distance metric used was the Euclidean distance but the Mahalanobis distance was also used in one case. The algorithm employed to compare fingerprints was the weighted k -nearest neighbor one. For Wi-Fi, with only three visible access points, accuracy ranged from 3.94 to 4.82 m, and precision from 5.21 to 7.0 m 90% of the time. With respect to BLE, with a low beacon density (1 beacon per 45.7 m²), accuracy ranged from 1.47 to 2.15 m, and precision from 1.81 to 3.58 m 90% of the time. Taking into account the fact that this system is designed to work in real situations in a scenario with high environmental fluctuations, and comparing the results with others obtained in laboratory scenarios, our results are promising and demonstrate that the system would be able to position users with these reasonable values of accuracy and precision.

Providing person-centered care is a fundamental value and guiding philosophy for all health care delivery across Catholic Health Initiatives. Exceptional service excellence with every patient and family encounter is one way in which this value is demonstrated. The consequences of treating every person with dignity, respect, and a positive attitude can have real benefit on clinical outcomes, individual healing, health system reputation, and financial incentives. In our changing health care landscape, there are now financial motivations to improve patient satisfaction. In addition, a connection can be drawn between our relationships with patients, their experience with an organization, and the subsequent philanthropic and charitable donation to that organization. This article describes one health care system's journey toward improved patient experience through service excellence infrastructure, standard processes, and expected service behaviors.

2003-01-01

Introduction: Selective dissemination of information (SDI) services regularly alert users to new information on their chosen topics. This type of service can increase a user's ability to keep current and may have a positive impact on efficiency and productivity. Currently, there are many venues available where users can establish, store, and automatically run MEDLINE searches. Purpose: To describe, evaluate, and compare SDI services for MEDLINE. Resources: The following SDI services were selected for this study: PubMed Cubby, BioMail, JADE, PubCrawler, OVID, and ScienceDirect. Methodology: Identical searches were established in four of the six selected SDI services and were run on a weekly basis over a period of two months. Eight search strategies were used in each system to test performance under various search conditions. The PubMed Cubby system was used as the baseline against which the other systems were compared. Other aspects were evaluated in all six services and include ease of use, frequency of results, ability to use MeSH, ability to access and edit existing search strategies, and ability to download to a bibliographic management program. Results: Not all MEDLINE SDI services retrieve identical results, even when identical search strategies are used. This study also showed that the services vary in terms of features and functions offered. PMID:14566377

The struggle for contested boundaries in the move to collaborative care teams in Australian maternity care.

McIntyre, Meredith; Francis, Karen; Chapman, Ysanne

2012-06-01

the maternity services reforms announced by the Australian government herald a process of major change. The primary maternity care reforms requires maternity care professionals to work collaboratively as equals in contrast to the current system which is characterised by unequal relationships. critical discourse analysis (CDA) using neoliberalism as an interpretive lens was employed to determine the positions of the respective maternity care professionals on the proposed reform and what purpose was served by their representations to the national review of maternity services. a CDA framework informed by Fairclough, linking textual and sociological analysis in a way that foregrounds issues of power and resistance, was undertaken. Data were collected from selected written submissions to the 2008 national review of maternity services representing the position of midwifery, obstetrics, general practitioners including rural doctors and maternity service managers. maternity care professionals yielded several discourses that were specific to the discipline with a number that were shared across disciplines. The rise in consumerism has changed historical positions of influence in maternity services policy. The once powerful obstetric position in determining the direction of policy has come under siege, isolated in the presence of a powerful alliance involving consumers, midwives, sympathetic maternity service managers and some medical professions. The midwifery voice has been heard, a historical first, supported by its presence as a member of the alliance. the struggle for contested boundaries is entering a new phase as maternity care professionals struggle with different perceptions of what multidisciplinary collaboration means in the delivery of primary maternity care.

Analysing the Zenith Tropospheric Delay Estimates in On-line Precise Point Positioning (PPP) Services and PPP Software Packages.

PubMed

Mendez Astudillo, Jorge; Lau, Lawrence; Tang, Yu-Ting; Moore, Terry

2018-02-14

As Global Navigation Satellite System (GNSS) signals travel through the troposphere, a tropospheric delay occurs due to a change in the refractive index of the medium. The Precise Point Positioning (PPP) technique can achieve centimeter/millimeter positioning accuracy with only one GNSS receiver. The Zenith Tropospheric Delay (ZTD) is estimated alongside with the position unknowns in PPP. Estimated ZTD can be very useful for meteorological applications, an example is the estimation of water vapor content in the atmosphere from the estimated ZTD. PPP is implemented with different algorithms and models in online services and software packages. In this study, a performance assessment with analysis of ZTD estimates from three PPP online services and three software packages is presented. The main contribution of this paper is to show the accuracy of ZTD estimation achievable in PPP. The analysis also provides the GNSS users and researchers the insight of the processing algorithm dependence and impact on PPP ZTD estimation. Observation data of eight whole days from a total of nine International GNSS Service (IGS) tracking stations spread in the northern hemisphere, the equatorial region and the southern hemisphere is used in this analysis. The PPP ZTD estimates are compared with the ZTD obtained from the IGS tropospheric product of the same days. The estimates of two of the three online PPP services show good agreement (<1 cm) with the IGS ZTD values at the northern and southern hemisphere stations. The results also show that the online PPP services perform better than the selected PPP software packages at all stations.

Evaluating a campaign GNSS velocity field derived from an online precise point positioning service

Traditional processing of Global Navigation Satellite System (GNSS) data using dedicated scientific software has provided the highest levels of positional accuracy, and has been used extensively in geophysical deformation studies. To achieve these accuracies a significant level of understanding and training is required, limiting their availability to the general scientific community. Various online GNSS processing services, now freely available, address some of these difficulties and allow users to easily process their own GNSS data and potentially obtain high quality results. Previous research into these services has focused on Continually Operating Reference Station (CORS) GNSS data. Less research exists on the results achievable with these services using large campaign GNSS data sets, which are inherently noisier than CORS data. Even less research exists on the quality of velocity fields derived from campaign GNSS data processed through online precise point positioning services. Particularly, whether they are suitable for geodynamic and deformation studies where precise and reliable velocities are needed. In this research, we process a very large campaign GPS data set (spanning 10 yr) with the online Jet Propulsion Laboratory Automated Precise Positioning Service. This data set is taken from a GNSS network specifically designed and surveyed to measure deformation through the central North Island of New Zealand. This includes regional CORS stations. We then use these coordinates to derive a horizontal and vertical velocity field. This is the first time that a large campaign GPS data set has been processed solely using an online service and the solutions used to determine a horizontal and vertical velocity field. We compared this velocity field to that of another well utilized GNSS scientific software package. The results show a good agreement between the CORS positions and campaign station velocities obtained from the two approaches. We discuss the implications of these results for how future GNSS campaign field surveys might be conducted and how their data might be processed.

Critical Zone Services as a Measure for Evaluating the Trade-offs in Intensively Managed Landscapes

NASA Astrophysics Data System (ADS)

Richardson, M.; Kumar, P.

2015-12-01

The Critical Zone includes the range of biophysical processes occurring from the top of the vegetation canopy to the weathering zone below the groundwater table. These services (Field et al. 2015) provide a measure to value processes that support the goods and services from our landscapes. In intensively managed landscapes the provisioning and regulating services are being altered through anthropogenic energy inputs so as to derive more agricultural productivity from the landscapes. Land use change and other alterations to the environment result in positive and/or negative net Critical Zone services. Through studies in the Critical Zone Observatory for Intensively Managed Landscapes (IMLCZO), this research seeks to answer questions such as: Are perennial bioenergy crops or annual replaced crops better for the land and surrounding environment? How do we evaluate the products and services from the land for the energy and resources we put in? Before the economic valuation of Critical Zone services, these questions seemed abstract. However, with developments such as Critical Zone services and life cycle assessments, they are more concrete. To evaluate the trade-offs between positive and negative impacts, life cycle assessments are used to create an inventory of all the energy inputs and outputs in a landscape management system. Total energy is computed by summing the mechanical energy used to construct tile drains, fertilizer, and other processes involved in intensely managed landscapes and the chemical energy gained by the production of biofuels from bioenergy crops. A multi-layer canopy model (MLCan) computes soil, water, and nutrient outputs for each crop type, which can be translated into Critical Zone services. These values are then viewed alongside the energy inputs into the system to show the relationship between agricultural practices and their corresponding ecosystem and environmental impacts.

Accessing timely rehabilitation services for a global aging society? Exploring the realities within Canada's universal health care system.

The proportion of older persons is increasing in developed and developing countries: this aging trend can be viewed as a two-edged sword. On the one hand, it represents remarkable successes regarding advances in health care; and on the other hand, it represents a considerable challenge for health systems to meet growing demand. A growing disequilibrium between supply and demand may be particularly challenging within publicly funding health systems that 'guarantee' services to eligible populations. Rehabilitation, including physical therapy, is a service that if provided in a timely manner, can maximize function and mobility for older persons, which may in turn optimize efficiency and effectiveness of overall health care systems. However, physical therapy services are not considered an insured service under the legislative framework of the Canadian health system, and as such, a complex public/private mix of funding and delivery has emerged. In this article, we explore the consequences of a public/private mix of physical therapy on timely access to services, and use the World Health Organization (WHO) health system performance framework to assess the extent to which the emerging system influences the goal of aggregated and equitable health. Overall, we argue that a shift to a public/private mix may not have positive influences at the population level, and that innovative approaches to deliver services would be desirable to strengthening rather than weaken the publicly funded system. We signal that strategies aimed at scaling up rehabilitation interventions are required in order to improve health outcomes in an evolving global aging society.

The broadband integrate services digital network (B-ISDN) is an emerging telecommunications technology that will meet most of the telecommunications networking needs in the mid-1990's to early next century. The satellite-based system is well positioned for providing B-ISDN service with its inherent capabilities of point-to-multipoint and broadcast transmission, virtually unlimited connectivity between any two points within a beam coverage, short deployment time of communications facility, flexible and dynamic reallocation of space segment capacity, and distance insensitive cost. On-board processing satellites, particularly in a multiple spot beam environment, will provide enhanced connectivity, better performance, optimized access and transmission link design, and lower user service cost. The following are described: the user and network aspects of broadband services; the current development status in broadband services; various satellite network architectures including system design issues; and various fast packet switch architectures and their detail designs.

Measuring service line competitive position. A systematic methodology for hospitals.

PubMed

Studnicki, J

1991-01-01

To mount a broad effort aimed at improving their competitive position for some service or group of services, hospitals have begun to pursue product line management techniques. A few hospitals have even reorganized completely under the product line framework. The benefits include focusing accountability for operations and results, facilitating coordination between departments and functions, stimulating market segmentation, and promoting rigorous examination of new and existing programs. As part of its strategic planning process, a suburban Baltimore hospital developed a product line management methodology with six basic steps: (1) define the service lines (which they did by grouping all existing diagnosis-related groups into 35 service lines), (2) determine the contribution of each service line to total inpatient volume, (3) determine trends in service line volumes (by comparing data over time), (4) derive a useful comparison group (competing hospitals or groups of hospitals with comparable size, scope of services, payer mix, and financial status), (5) review multiple time frames, and (6) summarize the long- and short-term performance of the hospital's service lines to focus further analysis. This type of systematic and disciplined analysis can become part of a permanent strategic intelligence program. When hospitals have such a program in place, their market research, planning, budgeting, and operations will be tied together in a true management decision support system.

High Altitude Platform Stations (HAPS) are recently considered as a green infrastructure to provide high speed multimedia services. The critical issue of HAPS is frequency sharing with satellite systems. Regulating antenna beam pattern using adaptive antenna schemes is one of means to facilitate the sharing with a space receiver for fixed satellite services on the uplink of a HAPS system operating in U bands. In this letter, we investigate antenna beam pattern characteristics of HAPS user terminals with various values of scan angles of main beam, null position angles, and null width.

The pre-hospital emergency medical and public safety information environment is nearing a threshold of significant change. The change is driven in part by several emerging technologies such as secure, high-speed wireless communication in the local and wide area networks (wLAN, 3G), Geographic Information Systems (GIS), Global Positioning Systems (GPS), and powerful handheld computing and communication services, that are of sufficient utility to be more widely adopted. We propose a conceptual model to enable improved clinical decision making in the pre-hospital environment using these change agents.

The Los Alamos Neutron Science Center (LANSCE) deploys many cylindrical beam position and phase monitors (BPPM) throughout the linac to measure the beam central position, phase and bunched-beam current. Each monitor is calibrated and qualified prior to installation to insure it meets LANSCE requirements. The BPPM wire mapping system is used to map the BPPM electrode offset, sensitivity and higher order coefficients. This system uses a three-axis motion table to position the wire antenna structure within the cavity, simulating the beam excitation of a BPPM at a fundamental frequency of 201.25 MHz. RF signal strength is measured and recorded formore » the four electrodes as the antenna position is updated. An effort is underway to extend the systems service to the LANSCE facility by replacing obsolete electronic hardware and taking advantage of software enhancements. This paper describes the upgraded wire positioning system's new hardware and software capabilities including its revised antenna structure, motion control interface, RF measurement equipment and Labview software upgrades. The main purpose of the wire mapping system at LANSCE is to characterize the amplitude response versus beam central position of BPPMs before they are installed in the beam line. The wire mapping system is able to simulate a beam using a thin wire and measure the signal response as the wire position is varied within the BPPM aperture.« less

How Environmental Uncertainty Moderates the Effect of Relative Advantage and Perceived Credibility on the Adoption of Mobile Health Services by Chinese Organizations in the Big Data Era.

Despite the importance of adoption of mobile health services by an organization on the diffusion of mobile technology in the big data era, it has received minimal attention in literature. This study investigates how relative advantage and perceived credibility affect an organization's adoption of mobile health services, as well as how environmental uncertainty changes the relationship of relative advantage and perceived credibility with adoption. A research model that integrates relative advantage, perceived credibility, environmental uncertainty, and an organization's intention to use mobile health service is developed. Quantitative data are collected from senior managers and information systems managers in 320 Chinese healthcare organizations. The empirical findings show that while relative advantage and perceived credibility both have positive effects on an organization's intention to use mobile health services, relative advantage plays a more important role than perceived credibility. Moreover, environmental uncertainty positively moderates the effect of relative advantage on an organization's adoption of mobile health services. Thus, mobile health services in environments characterized with high levels of uncertainty are more likely to be adopted because of relative advantage than in environments with low levels of uncertainty.

To ensure the reliable service of geostationary earth orbiting (GEO) communication satellites during the period of in-orbit, the hardware design life of each system usually has some redundancies in contrast to the limited fuel used to keep the satellite position and attitude. After the brief analysis of the life of the satellite subsystems, the feasibility of turning the decommissioned GEO communication satellites into slightly inclined geosynchronous orbiting (SIGSO) satellites is proved. In addition, the role and the actual usage of SIGSO satellites in Chinese Area Positioning System (CAPS) are analysed and discussed, including the effect on the improvement of Position Dilution of Precision (PDOP) of the navigation constellation and the application to satellite communication system, thus the potential value of satellite material and devices is exploited.

NASA's global differential GPS system and the TDRSS augmentation service for satellites

2004-01-01

NASA is planning to launch a new service for Earth satellites providing them with precise GPS differential corrections and other ancillary information enabling decimeter level orbit determination accuracy, and nanosecond time-transfer accuracy, onboard, in real-time. The TDRSS Augmentation Service for Satellites (TASS) will broadcast its message on the S-band multiple access channel of NASA's Tracking and Data Relay Satellite System (TDRSS). The satellite's phase array antenna has been configured to provide a wide beam, extending coverage up to 1000 km altitude over the poles. Global coverage will be ensured with broadcast from three or more TDRSS satellites. The GPS differential corrections are provided by the NASA Global Differential GPS (GDGPS) System, developed and operated by NASA's Jet Propulsion Laboratory. The GDGPS System employs a global ground network of more than 70 GPS receivers to monitor the GPS constellation in real time. The system provides real-time estimates of the GPS satellite states, as well as many other real-time products such as differential corrections, global ionospheric maps, and integrity monitoring. The unique multiply redundant architecture of the GDGPS System ensures very high reliability, with 99.999% demonstrated since the inception of the system in Early 2000. The estimated real time GPS orbit and clock states provided by the GDGPS system are accurate to better than 20 cm 3D RMS, and have been demonstrated to support sub-decimeter real time positioning and orbit determination for a variety of terrestrial, airborne, and spaceborne applications. In addition to the GPS differential corrections, TASS will provide real-time Earth orientation and solar flux information that enable precise onboard knowledge of the Earth-fixed position of the spacecraft, and precise orbit prediction and planning capabilities. TASS will also provide 5 seconds alarms for GPS integrity failures based on the unique GPS integrity monitoring service of the GDGPS System.

Objectives To identify opportunities within nationally representative surveys and surveillance systems to measure indicators of sexual health, we reviewed and inventoried existing data systems that include variables relevant to sexual health. Methods We searched for U.S. nationally representative surveys and surveillance systems that provided individual-level sexual health data. We assessed the methods of each data system and catalogued them by their measurement of the following domains of sexual health: knowledge, communication, attitudes, service access and utilization, sexual behaviors, relationships, and adverse health outcomes. Results We identified 18 U.S.-focused, nationally representative data systems: six assessing the general population, seven focused on special populations, and five addressing health outcomes. While these data systems provide a rich repository of information from which to assess national measures of sexual health, they present several limitations. Most importantly, apart from data on service utilization, routinely gathered, national data are currently focused primarily on negative aspects of sexual health (e.g., risk behaviors and adverse health outcomes) rather than more positive attributes (e.g., healthy communication and attitudes, and relationship quality). Conclusion Nationally representative data systems provide opportunities to measure a broad array of domains of sexual health. However, current measurement gaps indicate the need to modify existing surveys, where feasible and appropriate, and develop new tools to include additional indicators that address positive domains of sexual health of the U.S. population across the life span. Such data can inform the development of effective policy actions, services, prevention programs, and resource allocation to advance sexual health. PMID:23450886

2014-01-01

Design We introduced a long-term care facility (LTCF) Infectious Disease (ID) consult service (LID) that provides on-site consultations to residents of a VA LTCF. We determined the impact of the LID service on antimicrobial use and Clostridium difficile infections at the LTCF. Setting A 160-bed Veterans Affairs (VA) LTCF. Methods Systemic antimicrobial use and the rate of positive C. difficile tests at the LTCF were compared for 36 months before and 18 months after the initiation of the ID consultation service using segmented regression analysis of an interrupted time-series. Results In contrast to the pre-intervention period, total systemic antibiotic administration decreased by 30% (P <.001) with a significant reduction in both oral (32%; P<.001) and intravenous agents (25%; P =.008). The greatest reductions were seen for tetracyclines (64%, P <.001), clindamycin (61%; P <.001), sulfamethoxazole/trimethoprim (38%; P <.001), fluoroquinolones (38%; P <.001) and beta-lactam/beta-lactamase inhibitor combinations (28%; P <.001). Rates of change for positive C. difficile tests at the LTCF declined in the post- vs. preintervention periods (P = .04). Conclusions Implementation of a LTCF ID service led to a significant reduction in total antimicrobial use. Bringing providers with infectious disease expertise to the LTCF represents a new and effective means to achieve antimicrobial stewardship. PMID:23143354

The Patient Protection and Affordable Care Act - The Role of the School Nurse: Position Statement.

PubMed

2015-07-01

It is the position of the National Association of School Nurses that the registered professional school nurse (hereinafter referred to as the school nurse) serves a vital role in the delivery of health care to our nation’s students within the health care system reshaped by the Patient Protection and Affordable Care Act of 2010, commonly known as the Affordable Care Act (ACA). This law presents an opportunity to transform the health care system through three primary goals: expanding access, improving quality, and reducing cost (U.S. Government Printing Office, 2010). School nurses stand at the forefront of this system change and continue to provide evidence-based, quality interventions and preventive care that, according to recent studies, actually save health care dollars (Wang et al., 2014). NASN supports the concept that school nursing services receive the same financial parity as other health care providers to improve overall health outcomes, including insurance reimbursement for services provided to students.

1991-01-01

Use of the Tracking and Data Relay Satellite System (TDRSS) Onboard Navigation System (TONS) was proposed as an alternative to the Global Positioning System (GPS) for supporting the Earth Observing System (EOS) mission. The results are presented of EOS navigation performance evaluation with respect to TONS based orbit, time, and frequency determination (OD/TD/FD). Two TONS modes are considered: one uses scheduled TDRSS forward link service to derive one way Doppler tracking data for OD/FD support (TONS-I); the other uses an unscheduled navigation beacon service (proposed for Advanced TDRSS) to obtain pseudorange and Doppler data for OD/TD/FD support (TONS-II). Key objectives of the analysis were to evaluate nominal performance and potential sensitivities, such as suboptimal tracking geometry, tracking contact scheduling, and modeling parameter selection. OD/TD/FD performance predictions are presented based on covariance and simulation analyses. EOS navigation scenarios and the contributions of principal error sources impacting performance are also described. The results indicate that a TONS mode can be configured to meet current and proposed EOS position accuracy requirements of 100 and 50 m, respectively.

Fusion of navigational data in River Information Services

NASA Astrophysics Data System (ADS)

Kazimierski, W.

2009-04-01

River Information Services (RIS) is the complex system of solutions and services for inland shipping. It has been the scope of works carried out in most of European countries for last several years. There were also a few major pan-European projects like INDRIS or COMPRIS launched for these purposes. The main idea of RIS is to harmonize the activities of various companies, authorities and other users of inland waterways in Europe. In the last time growing activity in this area in Poland can be also noticed. The leading example can be the works carried out in Chair of Geoinformatics in Maritime University of Szczecin regarding RIS for the needs of Odra River. The Directive 2005/44/EC of European Parliament and Europe Council, followed by European Commission regulations, give precise guidelines on implementing RIS in Europe, stating the services that should be provided. Among them Traffic Information and Traffic Management services can be found. As per guidelines they should be based on tracking and tracing of ships in the inland waters. The results of tracking and tracing are Tactical Traffic Image and Strategic Traffic Image. The guidelines stated that, tracking and tracing system in RIS shall consist of various type sensors. The most important of them is thought to be Automatic Information System (AIS), and particularly its river version - Inland AIS. It is based on determining the position of ships by satellite positioning systems (mainly DGPS) and transmitting it to other users on radio VHF frequences. This guarantees usually high accuracy of data related to movement of ships (assuming proper functioning of system and ship's sensors), and gives the possibility of transmitting additional information about ship, like dimensions, port of destination, cargo, etc. However the other sensors that can be used for tracking shall not be forgotten. The most important of them are radar (traditionally used for tracking purposes in Vessel Traffic Systems) and video camera. Their main advantage over AIS is total independence from tracked target's facilities. For example, wrong indications of ship's GPS would affect AIS accuracy, but wouldn't have any impact on values estimated by radar. In addition to this in many times update rate for AIS data is longer than for radar. Thus, it can be noticed, that efficient tracking system introduced in RIS shall use both AIS receivers (based on satellite derived positions), and independent radar and camera sensors. This will however cause determining at least two different set of information about positions and movement parameters of targets. Doubled or multiplied vectors for single target are unacceptable, due to safety of navigation and traffic management. Hence the need of data fusion in RIS is obvious. The main goal is to develop unambiguous, clear and reliable information about ships' position and movement for all users in the system. Data fusion itself is not a new problem in maritime navigation. There are systems of Integrated Bridge on sea-going ships, which use information coming out from different sources. However the possibilities of integration of navigational information in the aspect of inland navigation, especially in River Information Services, still needs to be thoroughly surveyed. It is quite useful for simplifying the deduction, to introduce two data fusion levels. First of them is being done on board of the vessel. Its aim is to integrate all information coming from different sensors in the so called Integrated Navigational System. The other task of this fusion is to estimate reliable information about other objects based on AIS and radar. The second level is the integration of AIS, radar and closed-circuit television (CCTV) carried out in coastal station in order to determine Tactical and Strategic Traffic Image. The navigational information in RIS itself can be divided into two main groups. The first one is called static data and contains al basic information related to ship itself and the voyage, like dimensions, destination, etc. The second group is called dynamic data and contains all the information, which variability is important for creating Tactical Traffic Image. Both groups require different fusion algorithms, which take into consideration sources, update rate and method, accuracy and reliability. The article contains different issues related to navigational information fusion in River Information Services. It includes short description of structures and sources of navigational information and also the most popular integration methods. More detailed analysis was made for fusion of position derived from satellite systems (GPS) and from radar. The concept of tracking system, combining Inland AIS, radar and CCTV for the needs of RIS is introduced.

Car ownership in China reached 194 million vehicles at the end of 2016. The traffic congestion index (TCI) exceeds 2.0 during rush hour in some cities. Inefficient processing for minor traffic accidents is considered to be one of the leading causes for road traffic jams. Meanwhile, the process after an accident is quite troublesome. The main reason is that it is almost always impossible to get the complete chain of evidence when the accident happens. Accordingly, a police and insurance joint management system is developed which is based on high precision BeiDou Navigation Satellite System (BDS)/Global Positioning System (GPS) positioning to process traffic accidents. First of all, an intelligent vehicle rearview mirror terminal is developed. The terminal applies a commonly used consumer electronic device with single frequency navigation. Based on the high precision BDS/GPS positioning algorithm, its accuracy can reach sub-meter level in the urban areas. More specifically, a kernel driver is built to realize the high precision positioning algorithm in an Android HAL layer. Thus the third-party application developers can call the general location Application Programming Interface (API) of the original standard Global Navigation Satellite System (GNSS) to get high precision positioning results. Therefore, the terminal can provide lane level positioning service for car users. Next, a remote traffic accident processing platform is built to provide big data analysis and management. According to the big data analysis of information collected by BDS high precision intelligent sense service, vehicle behaviors can be obtained. The platform can also automatically match and screen the data that uploads after an accident to achieve accurate reproduction of the scene. Thus, it helps traffic police and insurance personnel to complete remote responsibility identification and survey for the accident. Thirdly, a rapid processing flow is established in this article to meet the requirements to quickly handle traffic accidents. The traffic police can remotely identify accident responsibility and the insurance personnel can remotely survey an accident. Moreover, the police and insurance joint management system has been carried out in Wuhan, Central China’s Hubei Province, and Wuxi, Eastern China’s Jiangsu Province. In a word, a system is developed to obtain and analyze multisource data including precise positioning and visual information, and a solution is proposed for efficient processing of traffic accidents.

The Navstar GPS master control station's Kalman filter experience

NASA Technical Reports Server (NTRS)

Scardera, Michael P.

1990-01-01

The Navstar Global Positioning System (GPS) is a highly accurate space based navigation system providing all weather, 24 hour a day service to both military and civilian users. The system provides a Gaussian position solution with four satellites, each providing its ephemeris and clock offset with respect to GPS time. The GPS Master Clock Station (MCS) is charged with tracking each Navstar spacecraft and precisely defining the ephemeris and clock parameters for upload into the vehicle's navigation message. Briefly described here are the Navstar system and the Kalman filter estimation process used by MCS to determine, predict, and ensure quality control for each of the satellite's ephemeris and clock states. Routine performance is shown. Kalman filter reaction and response is discussed for anomalous clock behavior and trajectory perturbations. Particular attention is given to MCS efforts to improve orbital adjust modeling. The satellite out of service time due to orbital maneuvering has been reduced in the past year from four days to under twelve hours. The planning, reference trajectory model, and Kalman filter management improvements are explained.

A starting point for delivery reform. Catholic healthcare providers can receive guidance from "A Time to Be Old, a Time to Flourish".

PubMed

1992-03-01

The ideal healthcare delivery system is client focused and ensures that the individual and the family receive the appropriate mix of services to meet their needs. Healthcare delivery should be presented as a coordinated continuum of care. Key integrating elements are essential to provide healthcare services on a day-by-day basis as a continuum of care. Integrating elements that form the bridge between clients and services include planning, care management, a management information system, financing, and an appropriate administrative structure. Many Catholic healthcare providers are expanding by acquiring a variety of services. However, many of these acquisitions are in response to today's competitive environment, whereas a true continuum of care must focus on the client's range of functional needs. Catholic providers must keep in mind that not all services they provide will be profitable. Although Catholic healthcare providers will be pressured to focus on fiscal strength and market position, they must put the client's holistic needs first. By doing so, they can help create a client-centered healthcare system in their communities.

Since 1982, the Crustal Dynamics Data Information System (CDDIS) has supported the archive and distribution of geodetic data products acquired by NASA programs. These data include GPS (Global Positioning System), GLONASS (GLObal NAvigation Satellite System), SLR (Satellite Laser Ranging), VLBI (Very Long Baseline Interferometry), and DORIS (Doppler Orbitography and Radiolocation Integrated by Satellite). The data archive supports NASA's space geodesy activities through the Solid Earth and Natural Hazards (SENH) program. The CDDIS data system and its archive have become increasingly important to many national and international programs, particularly several of the operational services within the International Association of Geodesy (IAG), including the International GPS Service (IGS), the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), the International DORIS Service (IDS), and the International Earth Rotation Service (IERS). The CDDIS provides easy and ready access to a variety of data sets, products, and information about these data. The specialized nature of the CDDIS lends itself well to enhancement and thus can accommodate diverse data sets and user requirements. All data sets and metadata extracted from these data sets are accessible to scientists through ftp and the web; general information about each data set is accessible via the web. The CDDIS, including background information about the system and its user communities, the computer architecture, archive contents, available metadata, and future plans will be discussed.

Do quality improvement systems improve health library services? A systematic review.

Gray, Hannah; Sutton, Gary; Treadway, Victoria

2012-09-01

A turbulent financial and political climate requires health libraries to be more accountable than ever. Quality improvement systems are widely considered a 'good thing to do', but do they produce useful outcomes that can demonstrate value? To undertake a systematic review to identify which aspects of health libraries are being measured for quality, what tools are being used and what outcomes are reported following utilisation of quality improvement systems. Many health libraries utilise quality improvement systems without translating the data into service improvements. Included studies demonstrate that quality improvement systems produce valuable outcomes including a positive impact on strategic planning, promotion, new and improved services and staff development. No impact of quality improvement systems on library users or patients is reported in the literature. The literature in this area is sparse and requires updating. We recommend further primary research is conducted in health libraries focusing upon the outcomes of utilising quality improvement systems. An exploration of quality improvement systems in other library sectors may also provide valuable insight for health libraries. © 2012 The authors.

Accuracy and reliability of multi-GNSS real-time precise positioning: GPS, GLONASS, BeiDou, and Galileo

NASA Astrophysics Data System (ADS)

Li, Xingxing; Ge, Maorong; Dai, Xiaolei; Ren, Xiaodong; Fritsche, Mathias; Wickert, Jens; Schuh, Harald

2015-06-01

In this contribution, we present a GPS+GLONASS+BeiDou+Galileo four-system model to fully exploit the observations of all these four navigation satellite systems for real-time precise orbit determination, clock estimation and positioning. A rigorous multi-GNSS analysis is performed to achieve the best possible consistency by processing the observations from different GNSS together in one common parameter estimation procedure. Meanwhile, an efficient multi-GNSS real-time precise positioning service system is designed and demonstrated by using the multi-GNSS Experiment, BeiDou Experimental Tracking Network, and International GNSS Service networks including stations all over the world. The statistical analysis of the 6-h predicted orbits show that the radial and cross root mean square (RMS) values are smaller than 10 cm for BeiDou and Galileo, and smaller than 5 cm for both GLONASS and GPS satellites, respectively. The RMS values of the clock differences between real-time and batch-processed solutions for GPS satellites are about 0.10 ns, while the RMS values for BeiDou, Galileo and GLONASS are 0.13, 0.13 and 0.14 ns, respectively. The addition of the BeiDou, Galileo and GLONASS systems to the standard GPS-only processing, reduces the convergence time almost by 70 %, while the positioning accuracy is improved by about 25 %. Some outliers in the GPS-only solutions vanish when multi-GNSS observations are processed simultaneous. The availability and reliability of GPS precise positioning decrease dramatically as the elevation cutoff increases. However, the accuracy of multi-GNSS precise point positioning (PPP) is hardly decreased and few centimeter are still achievable in the horizontal components even with 40 elevation cutoff. At 30 and 40 elevation cutoffs, the availability rates of GPS-only solution drop significantly to only around 70 and 40 %, respectively. However, multi-GNSS PPP can provide precise position estimates continuously (availability rate is more than 99.5 %) even up to 40 elevation cutoff (e.g., in urban canyons).

The purpose of this research was to study how drug exposed infants were processed, following a positive toxicology screen, through the Social Services and Juvenile Court system and to construct a demographic profile of these cases. Using data (N = 284) from Social Services and Juvenile Court files in one large county this paper describes the socioeconomic profile of cases in the Social Services and Court system over an 18-month period and tracks the progress of these cases through their reviews and hearings. The data show an overrepresentation of African American and Hispanic cases compared to the relevant county population and an underrepresentation of Caucasian and Asian cases. A petition to Juvenile Court was filed in almost half of the initial cases. Among the children who were made dependents of the court, about 80% were removed from the mother and placed in reunification services. Of these one third were later returned to the family while the rest went to permanency placements outside the home.

A systems perspective on research and treatment with abused and neglected children.

PubMed

Clyman, R B

2000-01-01

To discuss two systems-level changes in the organization and financing of mental health and child welfare services that will increasingly affect abused and neglected children: the implementation of managed care processes and the incorporation of accountability mechanisms in the management of mental health and child welfare services, particularly the use of systematic outcomes assessments. A central goal of the paper is to identify critical research questions which will help us to understand the impact of these changes on maltreated children. These two systems-level changes are described, and ways they may affect maltreated children are addressed. Both managed care and the growing focus on managing services by monitoring outcomes may positively or negatively affect maltreated children. Both of these trends are affecting the mental health and child welfare systems. It is likely that they will affect maltreated children's access to and the quality, cost, and outcomes of mental health and child welfare services. Systematic research on the impact of these large-scale changes can increase the likelihood that these changes will benefit maltreated children. A number of critical areas are identified for future research.

Although an interdisciplinary approach is considered best practice for caring for patients at the end of life, or in need of palliative care (PC) services, there is growing tension between healthcare organizations' need to contain costs and the provision of this beneficial, yet resource-intensive service. To support the interdisciplinary team (IDT) approach by recognizing organizations, teams, patients, and families as complex adaptive systems, illustrated by a qualitative study of the experiences, roles, and attributes of healthcare professionals (HCPs) who work with patients in need of PC services. In-depth, semi-structured interviews of PC health professionals were conducted, transcribed, and independently reviewed using grounded theory methodology and preliminary interpretations. A combined deductive and inductive iterative qualitative approach was used to identify recurring themes. The study was conducted in a physician-led, not-for-profit, multispecialty integrated health system serving three large, Western, rural states. A purposive sample of 10 HCPs who regularly provide PC services were interviewed. A positive team/patient experience was related to individual attributes, including self-awareness, spirit of inquiry, humility, and comfort with dying. IDT attributes included shared purpose, relational coordination, holistic thinking, trust, and respect for patient autonomy. Professional and personal motivations also contributed to a positive team/patient experience. Interdisciplinary PC teams have the potential to significantly impact patient and team experiences when caring for seriously ill patients. Findings from this study support interventions that focus on relationship building and application of a complex systems theory approach to team development.

Combined Global Navigation Satellite Systems in the Space Service Volume

Besides providing position, navigation, and timing (PNT) services to traditional terrestrial and airborne users, GPS is also being increasingly used as a tool to enable precision orbit determination, precise time synchronization, real-time spacecraft navigation, and three-axis attitude control of Earth orbiting satellites. With additional Global Navigation Satellite System (GNSS) constellations being replenished and coming into service (GLONASS, Beidou, and Galileo), it will become possible to benefit from greater signal availability and robustness by using evolving multi-constellation receivers. The paper, "GPS in the Space Service Volume," presented at the ION GNSS 19th International Technical Meeting in 2006 (Ref. 1), defined the Space Service Volume, and analyzed the performance of GPS out to seventy thousand kilometers. This paper will report a similar analysis of the signal coverage of GPS in the space domain; however, the analyses will also consider signal coverage from each of the additional GNSS constellations noted earlier to specifically demonstrate the expected benefits to be derived from using GPS in conjunction with other foreign systems. The Space Service Volume is formally defined as the volume of space between three thousand kilometers altitude and geosynchronous altitude circa 36,000 km, as compared with the Terrestrial Service Volume between 3,000 km and the surface of the Earth. In the Terrestrial Service Volume, GNSS performance is the same as on or near the Earth's surface due to satellite vehicle availability and geometry similarities. The core GPS system has thereby established signal requirements for the Space Service Volume as part of technical Capability Development Documentation (CDD) that specifies system performance. Besides the technical discussion, we also present diplomatic efforts to extend the GPS Space Service Volume concept to other PNT service providers in an effort to assure that all space users will benefit from the enhanced interoperability of GNSS services in the space domain. A separate paper presented at the conference covers the individual GNSS performance parameters for respective Space Service Volumes.

Increasing your HCAHPS scores with Extreme Customer Service.

Providing great customer service is extremely critical in the healthcare setting, especially when it comes to HCAHBPS (Hospital Consumer Assessment of Health care Providers and Systems) scores, the author says. While there are several service training programs within healthcare, they often require six to eight minutes of interaction with patients or guests. This works well for clinical staff, he says, but when it comes to non-clinical staff, including security officers, many times they only have fifteen or thirty seconds to create positive patient or guest experience. In this article he describes Extreme Customer Service © a program he has developed to fill that customer gap for non-clinical staff.

2012-12-01

The International Earth Rotation and Reference Systems Service (IERS) is a joint service of the International Association of Geodesy (IAG) and the International Astronomical Union (IAU), which provides the scientific community with the means for computing the transformation from the International Celestial Reference System (ICRS) to the International Terrestrial Reference System (ITRS). It further maintains the realizations of these systems by appropriate coordinate sets called "frames". The densification of terrestrial frame usually serves as official frame for positioning and navigation tasks within the territory of particular country. One of these densifications was recently performed in order to establish new reference frame for Republic of Serbia. The paper describes related activities resulting in ETRF2000 as a new Serbian terrestrial reference frame.

Reimbursement for school nursing health care services: position statement.

Children come to school with a variety of health conditions, varying from moderate health issues to multiple, severe chronic health illnesses that have a profound and direct impact on their ability to learn. The registered professional school nurse (hereinafter referred to as school nurse) provides medically necessary services in the school setting to improve health outcomes and promote academic achievement. The nursing services provided are reimbursable services in other health care settings, such as hospitals, clinics, and home care settings. The National Association of School Nurses (NASN) believes that school nursing services that are reimbursable nursing services in other health care systems should also be reimbursable services in the school setting, while maintaining the same high quality care delivery standards. Traditionally, local and state tax revenues targeted to fund education programs have paid for school nursing health services. School nurses are in a strategic position to advocate for improving clinical processes to better fit with community health care providers and to align reimbursements with proposed changes. Restructuring reimbursement programs will enable health care funding streams to assist in paying for school nursing services delivered to students in the school setting. Developing new innovative health financing opportunities will help to increase access, improve quality, and reduce costs. The goal is to promote a comprehensive and cost-effective health care delivery model that integrates schools, families, providers, and communities.

When Michael Henry wanted to start an aerial video service, he turned to Johnson Space Center for assistance. Two NASA engineers - one had designed and developed TV systems in Apollo, Skylab, Apollo- Soyuz and Space Shuttle programs - designed a wing-mounted fiberglass camera pod. Camera head and angles are adjustable, and the pod is shaped to reduce vibration. The controls are located so a solo pilot can operate the system. A microprocessor displays latitude, longitude, and bearing, and a GPS receiver provides position data for possible legal references. The service has been successfully utilized by railroads, oil companies, real estate companies, etc.

TIANDITU (Map World) is the public version of the National Platform for Common Geospatial Information Service, and the travelling channel is TIANDITU-based geographic information platform for travelling service. With the development of tourism, traditional ways for providing travelling information cannot meet the needs of travelers. As such, the travelling channel of TIANDITU focuses on providing travel information abundantly and precisely, which integrated the geographic information data of TIANDITU Version 2.0 and the authoritative information resources from China National Tourism Administration. Furthermore, spatial positioning, category and information query of various travelling information were offered for the public in the travelling channel. This research mainly involves three important parts: the system design, key technologies of the system design and application examples. Firstly, this paper introduced the design of TIANDITU-based geographic information system for travelling service, and the general and database design were described in detail. The designs for general, database and travelling service above should consider lots of factors which illustrated in the paper in order to guarantee the efficient service. The process of system construction, the content of geographic information for travelling and system functions of geographic information for travelling are also proposed via diagram in this part. Then several key technologies were discussed, including the travelling information integration for main node and among nodes, general architecture design and management system for travelling channel, web portals and system interface. From the perspective of main technologies, this part describes how TIANDITU travelling channel can realize various functions and reach the requirements from different users. Finally, three application examples about travelling information query were listed shortly. The functions and search results are shown clearly in this part. In all, TIANDITU-based geographic information system for travelling service aimed to integrate the travelling information resources from national, provincial and municipal levels, and finally realized to provide "one stop" travelling service for users in the end.

Linking satellite ICT application businesses with regional innovation centers and investors: The EC “INVESaT” project

Ghiron, Florence; Kreisel, Joerg

2009-09-01

In the sector of information and communication technologies (ICT), whether in the USA, Japan, or Europe, innovative services are already in use, based on large-scale space-based infrastructure investments. Such systems are e.g. earth observation, telecommunication, and navigation, timing and positioning satellites. In combination with the advent of powerful handheld terminals and the demand for ubiquitous services, it is expected that info-mobility applications will reveal new sources of business in the years ahead, using in particular the Earth observation and future GALILEO systems to position any feature or user anywhere in the world within a few meter accuracy. Hence, satellite-based capabilities provide new and unique opportunities for economic stimulation and development. Many incubators and innovation centers in Europe have already grasped this growth potential. Yet, for many European players business growth appears below expectations compared to developments in the USA following the launch of GPS (Global Positioning System). Europe still has to overcome intrinsic barriers to seize these new business opportunities faster and with more visible economic impact by leveraging on SMEs and regional innovation centers to expand the commercial utilization of satellite capabilities and mobilization of appropriate financial resources. The paper elaborates on the INVESat project (funded by the EuropeInnova—European Commission), which aims at bridging the gap between Innovative enterprises and financial In VEstors in the emerging markets of SaTellite applications. The critical success factors required to stimulate and support more efficiently investments in this bread of innovative services will also be highlighted.

Anticipating the potential for positive uptake and adaptation in the implementation of a publicly funded online STBBI testing service: a qualitative analysis.

Online health services are a rapidly growing aspect of public health provision, including testing for sexually transmitted and other blood-borne infections (STBBI). Generally, healthcare providers, policymakers, and clients imbue online approaches with great positive potential (e.g., encouraging clients' agency; providing cost-effective services to more clients). However, the promise of online health services may vary across contexts and be perceived in negative or ambiguous ways (e.g., risks to 'gold standard' care provision; loss of provider control over an intervention; uncertainty related to budget implications). This study examines attitudes and perceptions regarding the development of a novel online STBBI testing service in Vancouver, Canada. We examine the perceptions about the intervention's potential by interviewing practitioners and planners who were engaged in the development and initial implementation of this testing service. We conducted in-depth interviews with 37 healthcare providers, administrators, policymakers, and community-based service providers engaged in the design and launch of the new online STBBI testing service. We also conducted observations during planning and implementation meetings for the new service. Thematic analysis techniques were employed to identify codes and broader discursive themes across the interview transcripts and observation notes. Some study participants expressed concern that the potential popularity of the new testing service might increase demand on existing sexual health services or become fiscally unsustainable. However, most participants regarded the new service as having the potential to improve STBBI testing in several ways, including reducing waiting times, enhancing privacy and confidentiality, appealing to more tech-savvy sub-populations, optimizing the redistribution of demands on face-to-face service provision, and providing patient-centred technology to empower clients to seek testing. Participants perceived this online STBBI testing service to have the potential to improve sexual health care provision. But, they also anticipated actions-and-reactions, revealing a need to monitor ongoing implementation dynamics. They also identified the larger, potentially system-transforming dimension of the new technology, which enables new system drivers (consumers) and reduces the amount of control health care providers have over online STBBI testing compared to conventional in-person testing.

Service user and family member perspectives on services for mental health, substance use/addiction, and violence: a qualitative study of their goals, experiences and recommendations.

Mental health and substance use disorders (MSD) are significant public health concerns that often co-occur with violence. To improve services that address MSD and violence [MSD(V)], it is critical to understand the perspectives of those most affected, people who have sought help for MSD(V) (i.e., "service users"), especially those with co-occurring issues, as well as their family members. We conducted structured interviews with 73 service users and 41 family members of service users in two Ontario communities (one urban, one rural) regarding their goals related to help-seeking, positive and negative experiences, and recommendations for improving systems of care. Overall, participants expressed a need for services that: (1) are respectful, nonjudgmental, and supportive, help service users to feel more 'normal' and include education to reduce stigma; (2) are accessible, varied and publicly funded, thereby meeting individual needs and addressing equity concerns at a systems level; and (3) are coordinated, holistic and inclusive of family members who often support service users. The findings provide a rich understanding of how service users and their families perceive services for MSD(V) issues and identify key ways to better meet their needs.

Forest Fire Mapping

1990-01-01

The Fire Logistics Airborne Mapping Equipment (FLAME) system, mounted in a twin-engine and airplane operated by the U.S. Forest Service (USFS) of the U.S. Department of Agriculture (USDA), is an airborne instrument for detecting and pinpointing forest fires that might escape ground detection. The FLAME equipment rack includes the operator interface, a video monitor, the system's control panel and film output. FLAME's fire detection sensor is an infrared line scanner system that identifies fire boundaries. Sensor's information is correlated with the aircraft's position and altitude at the time the infrared imagery is acquired to fix the fire's location on a map. System can be sent to a fire locale anywhere in the U.S. at the request of a regional forester. USFS felt a need for a more advanced system to deliver timely fire information to fire management personnel in the decade of the 1990s. The Jet Propulsion Laboratory (JPL) conducted a study, jointly sponsored by NASA and USDA, on what advanced technologies might be employed to produce an end-to-end thermal infrared fire detection and mapping system. That led to initiation of the Firefly system, currently in development at JPL and targeted for operational service beginning in 1992. Firefly will employ satellite-reference position fixing and provide performance superior to FLAME.

Understanding how orthopaedic surgery practices generate value for healthcare systems.

Olson, Steven A; Mather, Richard C

2013-06-01

Orthopaedic surgery practices can provide substantial value to healthcare systems. Increasingly, healthcare administrators are speaking of the need for alignment between physicians and healthcare systems. However, physicians often do not understand what healthcare administrators value and therefore have difficulty articulating the value they create in discussions with their hospital or healthcare organization. Many health systems and hospitals use service lines as an organizational structure to track the relevant data and manage the resources associated with a particular type of care, such as musculoskeletal care. Understanding service lines and their management can be useful for orthopaedic surgeons interested in interacting with their hospital systems. We provide an overview of two basic types of value orthopaedic surgeons create for healthcare systems: financial or volume-driven benefits and nonfinancial quality or value-driven patient care benefits. We performed a search of PubMed from 1965 to 2012 using the term "service line." Of the 351 citations identified, 18 citations specifically involved the use of service lines to improve patient care in both nursing and medical journals. A service line is a structure used in healthcare organizations to enable management of a subset of activities or resources in a focused area of patient care delivery. There is not a consistent definition of what resources are managed within a service line from hospital to hospital. Physicians can positively impact patient care through engaging in service line management. There is increasing pressure for healthcare systems and hospitals to partner with orthopaedic surgeons. The peer-reviewed literature demonstrates there are limited resources for physicians to understand the value they create when attempting to negotiate with their hospital or healthcare organization. To effectively negotiate for resources to provide the best care for patients, orthopaedic surgeons need to claim and demonstrate the value they create in healthcare organizations.

Galileo is the European satellite navigation system, financed by the European Space Agency (ESA) and the European Commission (EC). The Galileo System, currently under definition phase, will offer seamless global coverage, providing state-of-the-art positioning and timing services. Galileo services will include a standard service targeted at mass market users, an augmented integrity service, providing integrity warnings when fault occur and Public Regulated Services (ensuring a continuity of service for the public users). Other services are under consideration (SAR and integrated communications). Galileo will be interoperable with GPS, and will be complemented by local elements that will enhance the services for specific local users. In the frame of the Galileo definition phase, several system design and simulation facilities and test beds have been defined and developed for the coming phases of the project, respectively they are currently under development. These are mainly the following tools: Galileo Mission Analysis Simulator to design the Space Segment, especially to support constellation design, deployment and replacement. Galileo Service Volume Simulator to analyse the global performance requirements based on a coverage analysis for different service levels and degrades modes. Galileo System Simulation Facility is a sophisticated end-to-end simulation tool to assess the navigation performances for a complete variety of users under different operating conditions and different modes. Galileo Signal Validation Facility to evaluate signal and message structures for Galileo. Galileo System Test Bed (Version 1) to assess and refine the Orbit Determination &Time Synchronisation and Integrity algorithms, through experiments relying on GPS space infrastructure. This paper presents an overview on the so called "G-Facilities" and describes the use of the different system design tools during the project life cycle in order to design the system with respect to availability, continuity and integrity requirements. It gives more details on two of these system design tools: the Galileo Signal Validation Facility (GSVF) and the Galileo System Simulation Facility (GSSF). It will describe the operational use of these facilities within the complete set of design tools and especially the combined use of GSVF and GSSF will be described. Finally, this paper presents also examples and results obtained with these tools.

Left behind in the return-to-work journey: consumer insights for policy change and practice strategies.

2008-01-01

This study examined system barriers that precluded injured workers from accessing services and supports in the return-to-work (RTW) process. A grounded theory approach was used to investigate injured worker experiences. Methods included in-depth telephone interviews and the constant comparative method to analyze the data. Findings revealed that consumers experienced tensions or a tug-of-war between the RTW system, the health care system, and in accessing and using knowledge. Over time consumers reflected upon these tensions and initiated strategies to enhance return to function and RTW. Insights from consumer-driven strategies that might inform future policy change and promote positive service delivery for injured workers are examined.

International space Launch Services Today, ILS

NASA Astrophysics Data System (ADS)

Rymarcsuk, James A.; Haase, Ethan E.

2002-01-01

In the last five years the international space launch industry has undergone substantial change. New entrants and existing players in this market have introduced new and upgraded vehicles with greater lift capability than was available five years ago. In addition, some of these vehicles offer reduced risk from their predecessors thanks to design improvements and reductions in the number of failure points. The entry of these vehicles have generated greater supply, increased choice, and improved capabilities to the benefit of satellite operators and manufacturers. Some launch service providers have also enhanced the products and services they offer due to the increased competitiveness in the market. Although the number of commercial satellites launched per year has remained within a fairly narrow range in the last five years, expectations for the future that were once very optimistic have fallen dramatically. The significant number of commercial NGSO satellites launched in the late 1990s helped raise these expectations, but today, the predicted continued growth in launches due to NGSO and broadband systems has not materialized. Despite the decline in expectations from the late 1990s, however, the satellite market that the launch industry supports remains robust. Satellite operators maintain generally favorable financial positions, but the number of satellites required to provide services worldwide is growing slowly, with the number of new and replacement satellites launched per year remaining essentially flat. Satellite operators are undergoing consolidation that is rendering them stronger than ever, and putting them in a position to demand better service from their launch service providers. The increase in supply in the marketplace and the corresponding lack of growth in demand has led to a highly competitive marketplace for launch services internationally. ILS is well positioned with products and services to meet customer needs. Key customer buying factors include reliability and schedule assurance, in addition to price. The Atlas and Proton launch vehicles offered by ILS are based on long heritages, stretching across four decades of research, development, and operational experience. Compared to competing vehicles, Atlas and Proton present lower technical risk. ILS has also developed an innovative system for providing schedule assurance by using one vehicle to back up the other. This "mutual backup" service works because of the inherent similarities of the vehicles, and is unmatched by any other arrangement in the industry.

High-quality chest compressions during cardiopulmonary resuscitation (CPR) play a significant role in surviving cardiac arrest. Chest-compression quality can be measured and corrected by real-time CPR feedback devices, which are not yet commonly used. This article looks at the acceptance of such systems in comparison of equipped and unequipped personnel. Two groups of emergency medical services' (EMS) personnel were interviewed using standardized questionnaires. The survey was conducted in the German cities Dortmund and Münster. Overall, 205 persons participated in the survey: 103 paramedics and emergency physicians from the Dortmund fire service and 102 personnel from the Münster service. The staff of the Dortmund service were not equipped with real-time feedback systems. The test group of equipped personnel of the ambulance service of Münster Fire brigade uses real-time feedback systems since 2007. What is the acceptance level of real-time feedback systems? Are there differences between equipped and unequipped personnel? The total sample is receptive towards real-time feedback systems. More than 80% deem the system useful. However, this study revealed concerns and prejudices by unequipped personnel. Negative ratings are significantly lower at the Münster site that is experienced with the use of the real-time feedback system in contrast to the Dortmund site where no such experience exists-the system's use in daily routine results in better evaluation than the expectations of unequipped personnel. Real-time feedback systems receive overall positive ratings. Prejudices and concerns seem to decrease with continued use of the system.

China has become a major economic influence in Asia and globally. The country is in the position to further develop its workers' insurance and compensation system. This paper aims to introduce the existing workers' compensation policies, explain how these policies guide the operation of the occupational rehabilitation system for injured workers, and suggest ways to further develop an effective and sustainable system for the country. Major government policies and initiative documents and existing literature on occupational rehabilitation were critically reviewed. Shortfalls in our current system were identified and potential further development regimes were propose. Since 2004, China has implemented its national policy on providing timely and comprehensive rehabilitation and return-to-work interventions for workers who are injured at work. The three-tier medical and occupational rehabilitation system appears effective for enabling injured workers to access these services. Such a system is regarded as the most optimal for the country in spearheading the development of quality occupational rehabilitation services, and at the same time incorporating the existing expertise in acute medical care and rehabilitation within the public medical and health system. Problems encountered in the system can be classified under the culture, system and competence building aspects. The future workers' insurance and compensation system can probably put more emphasis on using bio-psychosocial and work disability prevention models in guiding its service development and delivery. Efforts need to be placed on building the competence of professionals in the system who provide services for injured workers. The empowerment of important stakeholders in the workers' insurance and compensation system and their inclusion in the planning of service delivery are crucial for developing a sustainable and effective system for China.

Role of information systems in public health services.

PubMed

Hartshorne, J E; Carstens, I L

1990-07-01

The purpose of this review is to establish a conceptual framework on the role of information systems in public health care. Information is indispensable for effective management and development of health services and therefore considered as an important operational asset or resource. A Health Information System is mainly required to support management and operations at four levels: namely transactional and functional; operational control; management planning and control; and strategic planning. To provide the necessary information needs of users at these levels of management in the health care system, a structured information system coupled with appropriate information technology is required. Adequate and relevant information is needed regarding population characteristics, resources available and expended, output and outcome of health care activities. Additionally information needs to be reliable, accurate, timely, easily accessible and presented in a compact and meaningful form. With a well-planned health information system health authorities would be in a position to provide a quality, cost-effective and efficient health service for as many people as need it, optimal utilisation of resources and to maintain and improve the community's health status.

Improving adolescent pregnancy outcomes and maternal health:a case study of comprehensive case managed services.

Our findings indicate how health outcomes regarding adolescent pregnancy and maternal and infant health care are intertwined with a case management process that fosters measures that are social in nature-the provision of direct services, as well as the encouragement of informal social supports systems. They also show how case managed services in a small, nongovernmental organization (NGO) with a strong commitment to its clients may provide the spontaneity and caring which results in a "match" between client needs and the delivery of services-and positive outcomes for pregnant women, early maternal health and infant health. The delivery of such case managed services in a manner which is intensive, comprehensive, flexible and integrated contributes significantly to such improved health outcomes.

1996-01-01

The NAVSTAR Global Positioning System (GPS) provides positioning and time information to military users via the Precise Positioning Service (PPS) which typically allows users a significant margin of precision over the commercially available Standard Positioning Service (SPS), Military sets that rely on first acquiring the SPS Coarse Acquisition (C/A) code, read from the data message the handover word (HOW) that provides the time-of-signal transmission needed to acquire and lock onto the PPS Y-code. Under extreme battlefield conditions, the use of GPS would be denied to the warfighter who cannot pick up the un-encrypted C/A code. Studies are underway at the GPS Joint Program Office (JPO) at the Space and Missile Center, Los Angeles Air Force Base that are aimed at developing the capability to directly acquire Y-code without first acquiring C/A code. This paper briefly outlines efforts to develop 'direct-Y' acquisition, and various approaches to solving this problem. The potential ramifications of direct-Y to military users are also discussed.

The Relationship Between Client Characteristics and Wraparound Services in Substance Use Disorder Treatment Centers.

The National Institute on Drug Abuse (NIDA) recommends a comprehensive treatment program for individuals with substance use disorder (SUD) in order to treat needs they often have in addition to their SUD. Specifically, NIDA suggests providing services related to the following issues: medical care, mental health care, HIV/AIDS, child care, educational, vocational, family counseling, housing, transportation, financial, and legal. By providing a comprehensive model that combines core and wraparound services, treatment centers can deliver a higher quality of treatment. In this article, we assessed the relationship between client characteristics and the availability of wraparound services in SUD treatment centers. We combined two nationally representative samples of treatment centers and used a negative binomial regression and a series of logistic regressions to analyze the relationship between client characteristics and wraparound services. On average, centers offered fewer than half of the wraparound services endorsed by NIDA. Our results indicated that client characteristics were significantly related to the provision of wraparound services. Most notably, the proportion of adolescent clients was positively related to educational services, the proportion of female clients was positively related to child care, but the proportion of clients referred from the criminal justice system was negatively associated with the provision of multiple wraparound services. Our findings have important implications for SUD clients and suggest that, although centers are somewhat responsive to their clients' ancillary needs, most centers do not offer the majority of wraparound services.

Kim, Jae-Hoon; Min, Kyoung Sik; Yeo, Woon-Young

2014-01-01

The rapid growth of mobile communication and the proliferation of smartphones have drawn significant attention to location-based services (LBSs). One of the most important factors in the vitalization of LBSs is the accurate position estimation of a mobile device. The Wi-Fi positioning system (WPS) is a new positioning method that measures received signal strength indication (RSSI) data from all Wi-Fi access points (APs) and stores them in a large database as a form of radio fingerprint map. Because of the millions of APs in urban areas, radio fingerprints are seriously contaminated and confused. Moreover, the algorithmic advances for positioning face computational limitation. Therefore, we present a novel irregular grid structure and data analytics for efficient fingerprint map management. The usefulness of the proposed methodology is presented using the actual radio fingerprint measurements taken throughout Seoul, Korea. PMID:25302315

The U.S. domestic and international regulatory and policy milestones since 1982, when NASA filed its petition with the Federal Communications Commission (FCC) to establish the U.S. domestic Mobile Satellite Service (MSS), are described. In 1985, the FCC proposed to establish MSS services and allocate spectrum for such service. In 1986, the FCC allocated L-band spectrum for MSS. In 1987, at the Mobile World Administrative Radio Conference (MOB WARC-87), despite U.S., Canadian, and Mexican efforts, the WARC did not adopt a multi-service, generic MSS allocation. In 1989, the FCC licensed the first MSS system. After two decisions by the U.S. Court of Appeals, the FCC's licensing actions remain intact. The FCC also has permitted Comsat to provide international aeronautical and land MSS via the Inmarsat system. Inmarsat, however, may not serve the domestic U.S. market. In 1991, the FCC accepted applications for MSS systems, most of which were non-geostationary proposals, for operation in the Radiodetermination Satellite Service (RDSS) bands, and the VHF and UHF bands. In 1992, the FCC proposed rules for non-geostationary MSS systems and applied a negotiated rulemaking procedure to each. Also in 1992, the U.S. position for flexibility in existing MSS bands and for additional worldwide MSS allocations was adopted in large part at the 1992 World Administrative Radio Conference (WARC-92).

Received Signal Strength Database Interpolation by Kriging for a Wi-Fi Indoor Positioning System

PubMed Central

Jan, Shau-Shiun; Yeh, Shuo-Ju; Liu, Ya-Wen

2015-01-01

The main approach for a Wi-Fi indoor positioning system is based on the received signal strength (RSS) measurements, and the fingerprinting method is utilized to determine the user position by matching the RSS values with the pre-surveyed RSS database. To build a RSS fingerprint database is essential for an RSS based indoor positioning system, and building such a RSS fingerprint database requires lots of time and effort. As the range of the indoor environment becomes larger, labor is increased. To provide better indoor positioning services and to reduce the labor required for the establishment of the positioning system at the same time, an indoor positioning system with an appropriate spatial interpolation method is needed. In addition, the advantage of the RSS approach is that the signal strength decays as the transmission distance increases, and this signal propagation characteristic is applied to an interpolated database with the Kriging algorithm in this paper. Using the distribution of reference points (RPs) at measured points, the signal propagation model of the Wi-Fi access point (AP) in the building can be built and expressed as a function. The function, as the spatial structure of the environment, can create the RSS database quickly in different indoor environments. Thus, in this paper, a Wi-Fi indoor positioning system based on the Kriging fingerprinting method is developed. As shown in the experiment results, with a 72.2% probability, the error of the extended RSS database with Kriging is less than 3 dBm compared to the surveyed RSS database. Importantly, the positioning error of the developed Wi-Fi indoor positioning system with Kriging is reduced by 17.9% in average than that without Kriging. PMID:26343673

The ability to remotely detect and monitor oil spills is becoming increasingly important due to the high demand of oil-based products. Indeed, shipping routes are becoming very crowded and the likelihood of oil slick occurrence is increasing. In this frame, a fully integrated remote sensing system can be a valuable monitoring tool. We propose an integrated and interoperable system able to monitor ship traffic and marine operators, using sensing capabilities from a variety of electronic sensors, along with geo-positioning tools, and through a communication infrastructure. Our system is capable of transferring heterogeneous data, freely and seamlessly, between different elements of the information system (and their users) in a consistent and usable form. The system also integrates a collection of decision support services providing proactive functionalities. Such services demonstrate the potentiality of the system in facilitating dynamic links among different data, models and actors, as indicated by the performed field tests.

Efforts to develop Picture Archiving and Communications Systems (PACS) for the last ten years have concentrated mainly on developing systems for primary interpretation of digital radiological images. Much less attention has been paid to the clinical aspects of the radiology process. Clinical radiology services are an important component of the overall care delivery process, providing information and consultation services to referring physicians, the customers of radiology, in a timely fashion to aid in care decisions. Information management systems (IMS) are playing an increasingly central role in the care delivery process. No suitable commercial PACS or IMS products were available that could effectively provide for the requirements of the clinicians. We endeavored to fill this void at our institution by developing a system to deliver images and text reports electronically on-demand to the referring physicians. This system has evolved substantially since initial deployment eight years ago. As new technologies become available they are evaluated and integrated as appropriate to improve system performance and manageability. Not surprisingly, the internet and World Wide Web (WWW) technology has had the greatest impact on system design in recent years. Additional features have been added over time to provide services for teleradiology, teaching, and research needs. We also discovered that these value-added services give us a competitive edge in attracting new business to our department. Commercial web-based products are now becoming available which do a satisfactory job of providing many of these clinical services. These products are evaluated for integration into our system as they mature. The result is a system that impacts positively on patient care.

An evaluation of substance misuse treatment providers used by an employee assistance program.

Miller, N A

1992-05-01

Structural measures of access, continuity, and quality of substance misuse treatment services were compared in 30 fee-for-service (FFS) facilities and nine health maintenance organizations (HMOs). Probit models related effects of the provider system (FFS or HMO) and the system's structural characteristics to 243 employees' access to and outcomes from treatment. Access was decreased in Independent Practice Association (IPA)/network HMOs and in all facilities which did not employ an addictionologist or provide coordinated treatment services. When bivariate correlations were examined, both use of copayments and imposing limits to the levels of treatment covered were negatively related to access, while a facility's provision of ongoing professional development was positively associated with access. These correlations did not remain significant in the multivariate probits. Receiving treatment in a staff model HMO and facing limits to the levels of treatment covered were negatively associated with attaining sufficient progress, while receiving treatment in a facility which provided ongoing professional development was positively related to progress: these effects did not remain significant in multivariate analyses. Implications for employee assistance program (EAP) staff in their role as case managers and for EAP staff and employers in their shared role as purchasers of treatment are discussed.

Integration of services for Prevention of Mother-To-Child Transmission of HIV (PMTCT) into routine maternal and child health care is promoted as a priority strategy by the WHO to facilitate the implementation of PMTCT. Integration of services emphasizes inter-sectoral coordination in the health systems to provide convenient services for clients. China has been integrating prenatal HIV, syphilis and hepatitis B testing services since 2009. However, as the individual health systems are complex, effective coordination among different health agencies is challenging. Few studies have examined the factors that affect the coordination of such complex systems. The aim of this study is to assess the effectiveness of and examine challenges for integrated service delivery. Findings will provide the basis for strategy development to enhance the effective delivery of integrated services. The research was conducted in Guangdong province in 2013 using a needs assessment approach that includes qualitative and quantitative methods. Quantitative data was collected through a survey and from routine monitoring for PMTCT and qualitative data was collected through stakeholder interviews. Routine monitoring data used to assess key indicators of coordination suggested numerous coordination problems. The rates of prenatal HIV (95%), syphilis (47%) and hepatitis B (47%) test were inconsistent. An average of only 20% of the HIV positive mothers was referred in the health systems. There were no regular meetings among different health agencies and the clients indicated complicated service processes. The major obstacles to the coordination of delivering these integrated services are lack of service resource integration; and lack of a mechanism for coordination of the health systems, with no uniform guidelines, clear roles or consistent evaluation. The key obstacles that have been identified in this study hinder the coordination of the delivery of integrated services. Our recommendations include: 1) Facilitate integration of the funding and information systems by fully combining the service resources of different health agencies into one unit; 2) Establish regular meetings to facilitate exchange of information and address problems; 3) Establish a client referral network between different health agencies with agreed guidelines, clear roles and consistent evaluation.

Feature Positioning on Google Street View Panoramas

Location-based services (LBS) on web-based maps and images have come into real-time since Google launched its Street View imaging services in 2007. This research employs Google Maps API and Web Service, GAE for JAVA, AJAX, Proj4js, CSS and HTML in developing an internet platform for accessing the orientation parameters of Google Street View (GSV) panoramas in order to determine the three dimensional position of interest features that appear on two overlapping panoramas by geometric intersection. A pair of GSV panoramas was examined using known points located on the Library Building of National Chung Hsing University (NCHU) with the root-mean-squared errors of ±0.522m, ±1.230m, and ±5.779m for intersection and ±0.142m, ±1.558m, and ±5.733m for resection in X, Y, and h (elevation), respectively. Potential error sources in GSV positioning were analyzed and illustrated that the errors in Google provided GSV positional parameters dominate the errors in geometric intersection. The developed system is suitable for data collection in establishing LBS applications integrated with Google Maps and Google Earth in traffic sign and infrastructure inventory by adding automatic extraction and matching techniques for points of interest (POI) from GSV panoramas.

Quality improvement: the nurse's role.

PubMed

Moran, M J; Johnson, J E

1992-06-01

Continuous quality improvement is a concept which includes: Quality assurance--the provision of services that meet an appropriate standard. Problem resolution--including all departments involved in the issue at hand. Quality improvement--a continuous process involving all levels of the organization working together across departmental lines to produce better services for health care clients. Deming (1982b) and others have espoused total system reform to achieve quality improvement--not merely altering the current system, but radically changing it. It must be assumed that those who provide services at the staff level are acting in good faith and are not willfully failing to do what is correct (Berwick, 1991). Those who perform direct services are in an excellent position to identify the need for change in service delivery processes. Based on this premise, the staff nurse--who is at the heart of the system--is the best person to assess the status of health care services and to work toward improving the processes by which these services are provided to clients in the health care setting. The nurse manager must structure the work setting to facilitate the staff nurse's ability to undertake constructive action for improving care. The use of quality circles, quality councils, or quality improvement forums to facilitate the coordination of quality improvement efforts is an effective way to achieve success. The QA coordinator assists departments in documenting that the quality improvement efforts are effective across all departments of the organization, and aggregates data to demonstrate that they meet the requirements of external regulatory agencies, insurers, and professional standards. The nurse executive provides the vision and secures the necessary resources to ensure that the organization's quality improvement efforts are successful. By inspiring and empowering the staff in their efforts to improve the process by which health care is provided, nurse managers participate in reshaping the health care environment. The professional nurse plays a vital role in the quality improvement of health care services. However, nurses cannot make these improvements in a vacuum; they must include other professionals and ancillary personnel in their efforts. Total quality commitment must include all levels of an organization's structure. Quality patient care services will be achieved as the result of positive interactions among departments working together to build a dynamic mechanism that continuously improves the processes and outcomes of health care services.

Peace Corps Partnered Health Services Implementation Research in Global Health: Opportunity for Impact

Background: There is abundant evidence of the affordable, life-saving interventions effective at the local primary health care level in low- and middle-income countries (LMICs). However, the understanding of how to deliver those interventions in diverse settings is limited. Primary healthcare services implementation research is needed to elucidate the contextual factors that can influence the outcomes of interventions, especially at the local level. US universities commonly collaborate with LMIC universities, communities, and health system partners for health services research but common barriers exist. Current challenges include the capacity to establish an ongoing presence in local settings in order to facilitate close collaboration and communication. The Peace Corps is an established development organization currently aligned with local health services in many LMICs and is well-positioned to facilitate research partnerships. This article explores the potential of a community–Peace Corps–academic partnership approach to conduct local primary healthcare services implementation research. Discussion: The Peace Corps is well positioned to offer insights into local contextual factors because volunteers work closely with local leaders, have extensive trust within local communities, and have an ongoing, constant, well-integrated presence. However, the Peace Corps does not routinely conduct primary healthcare services implementation research. Universities, within the United States and locally, could benefit from the established resources and trust of the Peace Corps to conduct health services implementation research to advance access to local health services and further the knowledge of real world application of local health services in a diversity of settings. The proposed partnership would consist of (1) a local community advisory board and local health system leaders, (2) Peace Corps volunteers, and (3) a US-LMIC academic institutional collaboration. Within the proposed partnership approach, the contributions of each partner are as follows: the local community and health system leadership guides the work in consideration of local priorities and context; the Peace Corps provides logistical support, community expertise, and local trust; and the academic institutions offer professional technical and public health educational and training resources and research support. Conclusion: The Peace Corps offers the opportunity to enhance a community-academic partnership in LMICs through community-level guidance, logistical assistance, and research support for community based participatory primary health-care services implementation research that addresses local primary healthcare priorities.

2014-01-01

The European Association for Predictive, Preventive and Personalised Medicine (EPMA) considers acute problems in medical sciences as well as the quality and management of medical services challenging health care systems in Europe and worldwide. This actuality has motivated the representatives of EPMA to comment on the efforts in promoting an integrative approach based on multidisciplinary expertise to advance health care-related research and management. The current paper provides a global overview of the problems related to medical services: pandemic scenario in the progression of common non-communicable diseases, delayed interventional approaches of reactive medicine, poor economy of health care systems, lack of specialised educational programmes, problematic ethical aspects of several treatments as well as inadequate communication among professional groups and policymakers. In the form of individual paragraphs, the article presents a consolidated position of PPPM professionals towards the new European programme ‘Horizon 2020’ providing the long-lasting instruments for scientific and technological progress in medical services and health care-related programmes. In the author's opinion, Horizon 2020 provides unlimited room for research and implementation in Predictive, Preventive and Personalised Medicine. However, the overall success of the programme strongly depends on the effective communication and consolidation of professionals relevant for PPPM as well as the communication quality with policymakers. Smart political decision is the prerequisite of the effective PPPM implementation in the health care sector. This position is focused on the patients' needs, innovative medical sciences, optimal health and disease management, expert recommendations for the relevant medical fields and optimal solutions which have a potential to advance health care services if the long-term strategies were to be effectively implemented as proposed here.

1981-01-01

The market potential for photovoltaic systems in the agricultural sector of Colombia is assessed. Consideration was given to over twenty specific livestock production, crop production, and rural services applications requiring less than 15 kW of power without backup power. Analysis revealed that near-term potential exists for photovoltaic technology in applications in coffee depulging, cattle watering, rural domestic users, rural water supply and small irrigation, rural telephones, rural health posts, and vaccine refrigeration. Market size would be in the 1200 to 2500 kWp range in the 1981 to 86 timeframe. Positive factors influencing the market size include a lack of electrical services, potential for developing the Llanos Orientales Territory, high fuel costs in remote areas, balance of system availability, the presence of wealthy land owners, and a large government-sponsored contract for photovoltaic (PV)-powered rural telephone systems. The anticipated eligibility of photovoltaic equipment for loans would be a further positive factor in market potential. Important negative factors include relatively inexpensive energy in developed locations, reliance on hydropower, lack of familiarity with PV equipment, a lack of financing, and established foreign competition in PV technology. Recommendations to American PV manufacturers attempting to develop the Colombian market are given.

Health service providers play a crucial role in providing post abortion care in countries where abortion legislation is restrictive and abortion is stigmatised. Research in countries where these factors apply has shown that health service providers can be barriers to women accessing post abortion services. Much of this research draws from attitude theory. In this paper, we utilise positioning theory to show how the ways in which Zimbabwean health service providers' position women and themselves are rooted in cultural and social power relations. In light of recent efforts by the Zimbabwean Ministry of Health and foreign organisations to improve post abortion care, we explore the implications that these positionings have for post abortion care. As part of a larger study on abortion decision-making, the data featured in this article were collected using in-depth semi-structured interviews with six health service providers working in different facilities in Harare, Zimbabwe. Discursive and positioning thematic analysis was used to analyse the data. Our analysis points to women who have abortions being positioned in negative terms, as transgressors of acceptable norms; irresponsible and manipulative; and ignorant. The health service providers drew from cultural, religious, gender and trauma discourses that portray abortion as evil and socially unacceptable. Reflexive positions taken up by the health service providers include positions as being experts, helpers and protectors of culture/religion, sympathisers and professional positions as health care providers. The continued strengthening of post abortion services should be conducted in conjunction with dialogical interventions that challenge health service providers to reflect on the power relations within which women who terminate pregnancies are located, that contest their negative positionings of these women and that present alternative narratives and subject positionings for both the women who have abortions and the health service providers.

The location and contextual status (indoor or outdoor) is fundamental and critical information for upper-layer applications, such as activity recognition and location-based services (LBS) for individuals. In addition, optimizations of building management systems (BMS), such as the pre-cooling or heating process of the air-conditioning system according to the human traffic entering or exiting a building, can utilize the information, as well. The emerging mobile devices, which are equipped with various sensors, become a feasible and flexible platform to perform indoor-outdoor (IO) detection. However, power-hungry sensors, such as GPS and WiFi, should be used with caution due to the constrained battery storage on mobile device. We propose BlueDetect: an accurate, fast response and energy-efficient scheme for IO detection and seamless LBS running on the mobile device based on the emerging low-power iBeacon technology. By leveraging the on-broad Bluetooth module and our proposed algorithms, BlueDetect provides a precise IO detection service that can turn on/off on-board power-hungry sensors smartly and automatically, optimize their performances and reduce the power consumption of mobile devices simultaneously. Moreover, seamless positioning and navigation services can be realized by it, especially in a semi-outdoor environment, which cannot be achieved by GPS or an indoor positioning system (IPS) easily. We prototype BlueDetect on Android mobile devices and evaluate its performance comprehensively. The experimental results have validated the superiority of BlueDetect in terms of IO detection accuracy, localization accuracy and energy consumption. PMID:26907295

Emergency situations and mass casualties involve several agencies and public authorities, which need to gather data from the incident scene and exchange geo-referenced information to provide fast and accurate first aid to the people in need. Tracking patients on their way to the hospitals can prove critical in taking lifesaving decisions. Increased and continuous flow of information combined by vital signs and geographic location of emergency victims can greatly reduce the response time of the medical emergency chain and improve the efficiency of disaster medicine activity. Recent advances in mobile positioning systems and telecommunications are providing the technology needed for the development of location-aware medical applications. IMPRESS is an advanced ICT platform based on adequate technologies for developing location-aware medical response during emergencies. The system incorporates mobile and fixed components that collect field data from diverse sources, support medical location and situation-based services and share information on the patient's transport from the field to the hospitals. In IMPRESS platform tracking of victims, ambulances and emergency services vehicles is integrated with medical, traffic and crisis management information into a common operational picture. The Incident Management component of the system manages operational resources together with patient tracking data that contain vital sign values and patient's status evolution. Thus, it can prioritize emergency transport decisions, based on medical and location-aware information. The solution combines positioning and information gathered and owned by various public services involved in MCIs or large-scale disasters. IMPRESS solution, were validated in field and table top exercises in cooperation with emergency services and hospitals.

2016-01-01

In the existing centralized location services system structure, the server is easily attracted and be the communication bottleneck. It caused the disclosure of users’ location. For this, we presented a new distributed collaborative recommendation strategy that is based on the distributed system. In this strategy, each node establishes profiles of their own location information. When requests for location services appear, the user can obtain the corresponding location services according to the recommendation of the neighboring users’ location information profiles. If no suitable recommended location service results are obtained, then the user can send a service request to the server according to the construction of a k-anonymous data set with a centroid position of the neighbors. In this strategy, we designed a new model of distributed collaborative recommendation location service based on the users’ location information profiles and used generalization and encryption to ensure the safety of the user’s location information privacy. Finally, we used the real location data set to make theoretical and experimental analysis. And the results show that the strategy proposed in this paper is capable of reducing the frequency of access to the location server, providing better location services and protecting better the user’s location privacy.

Livingston, James D; Rossiter, Katherine R; Verdun-Jones, Simon N

2011-06-30

Increasingly, specialized 'forensic' mental health services are being developed to address the criminogenic and clinical needs of people with mental illness who are involved in the criminal justice system. Theoretically, the construction of such specialized services can produce simultaneous positive benefits and negative consequences. This mixed methods study examined and compared the level of self-stigma that was experienced by people who receive compulsory community-based treatment services in the forensic (n=52) and civil (n=39) mental health systems of British Columbia, Canada. The quantitative findings indicate that 'forensic' labelling was not associated with elevated levels of self-stigma. Quantitative level of self-stigma was significantly associated with psychiatric symptom severity, history of incarceration, and history of homelessness. The qualitative findings suggest that access to high-quality, well-resourced forensic mental health services may, for some service users, come at the risk of increased exposure to social and structural stigma. Together, these findings reveal some of the strengths and weaknesses that are associated with organizing forensic mental health services using a specialized service delivery model.

Bar-Sever, Y. E.

2016-12-01

The JPL Global Differential GPS (GDGPS) System is now producing real-time orbit and clock solutions for GPS, GLONASS, BeiDou, and Galileo. The operations are based on JPL's next generation geodetic analysis and data processing software, GIPSYx (also known at RTGx). We will examine the impact of the nascent GNSS constellations on real-time kinematic positioning for earthquake monitoring, and assess the marginal benefits from each constellation. We will discus the options for signal selection, inter-signal bias modeling, and estimation strategies in the context of real-time point positioning. We will provide a brief overview of the key features and attributes of GIPSYx. Finally we will describe the current natural hazard monitoring services from the GDGPS System.

Soudarin, L.; Ferrage, P.

2017-12-01

The International DORIS Service (IDS) was created in 2003 under the umbrella of the International Association of Geodesy (IAG) to foster scientific research related to the French satellite tracking system DORIS and to deliver scientific products, mostly related to the International Earth rotation and Reference systems Service (IERS). Since its start, the organization has continuously evolved, leading to additional and improved operational products from an expanded set of DORIS Analysis Centers. In addition, IDS has developed services for sharing data and products with the users. Metadata and interoperable web applications are proposed to explore, visualize and download the key products such as the position time series of the geodetic points materialized at the ground tracking stations. The Global Geodetic Observing System (GGOS) encourages the IAG Services to develop such interoperable facilities on their website. The objective for GGOS is to set up an interoperable portal through which the data and products produced by the IAG Services can be served to the user community. We present the web applications proposed by IDS to visualize time series of geodetic observables or to get information about the tracking ground stations and the tracked satellites. We discuss the future plans for IDS to meet the recommendations of GGOS. The presentation also addresses the needs for the IAG Services to adopt common metadata thesaurus to describe data and products, and interoperability standards to share them.

A spatial national health facility database for public health sector planning in Kenya in 2008.

Efforts to tackle the enormous burden of ill-health in low-income countries are hampered by weak health information infrastructures that do not support appropriate planning and resource allocation. For health information systems to function well, a reliable inventory of health service providers is critical. The spatial referencing of service providers to allow their representation in a geographic information system is vital if the full planning potential of such data is to be realized. A disparate series of contemporary lists of health service providers were used to update a public health facility database of Kenya last compiled in 2003. These new lists were derived primarily through the national distribution of antimalarial and antiretroviral commodities since 2006. A combination of methods, including global positioning systems, was used to map service providers. These spatially-referenced data were combined with high-resolution population maps to analyze disparity in geographic access to public health care. The updated 2008 database contained 5,334 public health facilities (67% ministry of health; 28% mission and nongovernmental organizations; 2% local authorities; and 3% employers and other ministries). This represented an overall increase of 1,862 facilities compared to 2003. Most of the additional facilities belonged to the ministry of health (79%) and the majority were dispensaries (91%). 93% of the health facilities were spatially referenced, 38% using global positioning systems compared to 21% in 2003. 89% of the population was within 5 km Euclidean distance to a public health facility in 2008 compared to 71% in 2003. Over 80% of the population outside 5 km of public health service providers was in the sparsely settled pastoralist areas of the country. We have shown that, with concerted effort, a relatively complete inventory of mapped health services is possible with enormous potential for improving planning. Expansion in public health care in Kenya has resulted in significant increases in geographic access although several areas of the country need further improvements. This information is key to future planning and with this paper we have released the digital spatial database in the public domain to assist the Kenyan Government and its partners in the health sector.

Escaping from poverty trap: a choice between government transfer payments and public services.

Anti-poverty has always been an important issue to be settled. What policies should be selected to help individuals escaping from the poverty trap: by directly offering transfer payments or indirectly providing public services? This paper is among the first to explore the effects of public anti-poverty programs system in China. We Using unbalanced panel data of China Health and Nutrition Survey (CHNS) from 1989 to 2009, we demonstrate how the individual poverty status is determined through a four-staged simultaneous model. We choose the 3SLS (Three Staged Linear Squared) methodology to do the estimation. GTPs (Government Transfer Payments) don't have positive effects on poverty reductions. The results demonstrate that GTPs increasing by 10% makes private transfer payments decrease by 3.9%. Meanwhile, GTPs increasing by 10% makes the household income decreased by 27.1%. However, public services (such as medical insurance, health services, hygiene protection etc.) have significantly positive impacts on poverty reduction. Public services share a part of living cost of the poor, and are conducive for people to gain higher household income. GTPs given by governments are not effective in reducing the poverty, as a result of "crowd-out effect" and "inductive effect". However, public services are suggested to be adopted by governments to help the poor out of the poverty trap.

It is estimated that several thousand transponders will be needed in the 36 MHz slot by the year 2000 by the U.S. and Japan, while the GEO position above the U.S. will be congested and the slot above Japan is shared by the Soviets. Additional demands may arise from the development of mobile communications services in Japan and the U.S. A large GEO platform could benefit from the economies of scale by making servicing an economical prospect. The platform could carry 50/40 GHz antennas for personal radio communications, multibeam DBS antennas, a mobile telephone system functioning at 900/800 MHz, a relay station for earth-moon communications, and global data relay system. The limitations and necessary operational parameters of each system are examined.

Use of negotiated rulemaking in developing technical rules for low-Earth orbit mobile satellite systems

NASA Technical Reports Server (NTRS)

Taylor, Leslie A.

1993-01-01

Technical innovations have converged with the exploding market demand for mobile telecommunications to create the impetus for low-earth orbit (LEO) communications satellite systems. The so-called 'Little LEO's' propose use of VHF and UHF spectrum to provide position - location and data messaging services. The so-called 'Big LEO's' propose to utilize the RDSS bands to provide voice and data services. In the United States, several applications were filed with the U.S. Federal Communications Commission (FCC) to construct and operate these mobile satellite systems. To enable the prompt introduction of such new technology services, the FCC is using innovative approaches to process the applications. Traditionally, when the FCC is faced with 'mutually exclusive' applications, e.g. a grant of one would preclude a grant of the others, it uses selection mechanisms such as comparative hearings or lotteries. In the case of the LEO systems, the FCC has sought to avoid these time-consuming approaches by using negotiated rulemakings. The FCC's objective is to enable the multiple applicants and other interested parties to agree on technical and service rules which will enable the grant of all qualified applications. With regard to the VHF/UHF systems, the Advisory Committee submitted a consensus report to the FCC. The process for the systems operating in the bands above 1 GHz involved more parties and more issues but still provided the FCC useful technical information to guide the adoption of rules for the new mobile satellite service.

Mobile apps provide diverse services and various convenient functions. This study applied the modified technology acceptance model (MTAM) in information systems research to the use of the mobile hospital registration system in Taiwan. The MTAM posits that perceived ease of use and perceived usefulness of technology influence users' attitudes toward using technology. Research studies using MTAM have determined information technology experience as a factor in predicting attitude. The objective of this present study is to test the validity of the MTAM model when it is being applied to the mobile registration system. The data was collected from 501 patients in a Taiwan's medical center. Path analysis results have shown that TAM is an applicable model in examining factors influencing users' attitudes of using the mobile registration system. It can be found that the perceived usefulness and the perceived ease of use are positively associated with users' attitudes toward using the mobile registration system, and they can improve users' attitudes of using it. In addition, the perceived ease of use is positively associated with the perceived usefulness. As for the personal prior experience, the information technology experience is positively associated with perceived usefulness and the perceived ease of use.

a New Ubiquitous-Based Indoor Positioning System with Minimum Extra Hardware Using Smart Phones

Knowing the position has been an ambition in many areas such as science, military, business, etc. GPS was the realization of this wish in 1970s. Technological advances such as ubiquitous computing, as a conquering perspective, requires any service to work for any user, any place, anytime, and via any network. As GPS cannot provide services in indoor environments, many scientists began to develop indoor positioning systems (IPS). Smart phones penetrating our everyday lives were a great platform to host IPS applications. Sensors in smart phones were another big motive to develop IPS applications. Many researchers have been working on the topic developing various applications. However, the applications introduced lack simplicity. In other words, they need to install a step counter or smart phone on the ankle, which makes it awkward and inapplicable in many situations. In the current study, a new IPS methodology is introduced using only the usual embedded sensors in the smart phones. The robustness of this methodology cannot compete with those of the aforementioned approaches. The price paid for simplicity was decreasing robustness and complicating the methods and formulations. However, methods or tricks to harness the errors to an acceptable range are introduced as the future works.

Foster-to-adopt families can be viewed as systems that are influenced by many other systems (e.g., the legal system, the social service agency, and the birth family). The current qualitative study of 84 foster-to-adopt parents (members of 42 lesbian, gay, and heterosexual couples) examined the types of challenges that parents faced as they navigated multiple systems during the initial post-placement period. Some participants described the legal insecurity associated with their role as foster-to-adopt parents as impacting their personal well-being and their attachment to their children. Lack of support services and disorganization within social service agencies, as well as strained relationships with birth parents, were also identified as stressors for foster-to-adopt parents. Importantly, lesbian and gay participants faced additional concerns regarding the security of their placement, due to the possibility for discrimination within the various systems involved with the foster-to-adopt process. Participants as a whole also identified positive aspects of their experiences within various systems; for example, they appreciated child care subsidies, state-provided health insurance, and supportive social workers. Our findings provide insights into foster-to-adopt parents’ experiences during the initial post-placement period, and have implications for adoption services aimed to improve placement stability and enhance family functioning in foster-to-adopt families.

Global uptake of antenatal care (ANC) varies widely and is influenced by the value women place on the service they receive. Identifying outcomes that matter to pregnant women could inform service design and improve uptake and effectiveness. To undertake a systematic scoping review of what women want, need and value in pregnancy. Eight databases were searched (1994-2015) with no language restriction. Relevant journal contents were tracked via Zetoc. An initial analytic framework was constructed with findings from 21 papers, using data-mining techniques, and then developed using meta-ethnographic approaches. The final framework was tested with 17 more papers. All continents except Australia were represented. A total of 1264 women were included. The final meta-theme was: Women want and need a positive pregnancy experience, including four subthemes: maintaining physical and sociocultural normality; maintaining a healthy pregnancy for mother and baby (including preventing and treating risks, illness and death); effective transition to positive labour and birth; and achieving positive motherhood (including maternal self-esteem, competence, autonomy). Findings informed a framework for future ANC provision, comprising three equally important domains: clinical practices (interventions and tests); relevant and timely information; and pyschosocial and emotional support; each provided by practitioners with good clinical and interpersonal skills within a high quality health system. A positive pregnancy experience matters across all cultural and sociodemographic contexts. ANC guidelines and services should be designed to deliver it, and those providing ANC services should be aware of it at each encounter with pregnant women. Women around the world want ANC staff and services to help them achieve a positive pregnancy experience. © 2015 The Authors.

Epidermolysis bullosa (EB) is a rare, genetic skin condition that is complicated, distressing, and painful and permeates every aspect of patients' lives. Support services are essential for meeting the primary needs of patients and families living with EB; however, provision is challenged by many complex issues. In collaboration with the patient organization DEBRA Ireland, this research conducted an in-depth analysis of Irish healthcare support services for EB, with a view to moving towards an improved and sustainable care pathway. A sustainable community of practice model (SCOP), as a core construct provided a simplified framework when studying this complex system. The research utilized mixed methods, comprising individual interviews, questionnaires, and a participatory action research workshop based on a soft systems approach. The study engaged patients, family members, service providers, and policy developers. Findings emphasized that the complexities of life with EB are more than 'skin deep'. The lived experience of stakeholders revealed many levels of emotion, both positive and heart-rending. Despite the positive efforts of specialists in this field, inadequacies to meet the primary needs of people with EB, such as bandages-fundamental for survival-were highlighted. Participants reported challenges relating to understanding patients' needs, access to consistent services within hospitals and the community, time constraints, and the strong emotions evoked by this severe and rare disease. The study identified several areas that can be targeted to bring about improvements in meeting primary needs. Education and research at public, policy, and practice levels need to be prioritized. It is imperative that citizens move beyond an awareness that EB exists and demonstrate a consciousness about the importance of advocating and enabling seamless and sustainable support services through collective action.

Up till 2008 the Dutch mental health services came under the Dutch General Law on Special Medical Costs (AWBZ). Health insurers regarded the mental health services as 'black box'. In 2008 the mental health services were transferred to the basic health insurance system and the health insurers became responsible for the healthcare purchasing services. In the same year the mental health services began to use ROM to measure the effects of treatment and thereby improve the quality of treatment. To clarify the use that the insurers make of ROM. The developments in this field are described. The feedback supplied by ROM enables therapists to improve treatment. An additional benefit is that the mental health services are then in a position to improve quality at aggregate level and compare their own results with those of others. Nationally, ROM can provide health insurers with information about treatment quality in combination with the Consumer Quality Index (CQI), and national 'benchmarks' can be implemented. To facilitate the interpretation of these rom data the health insurers set up the independent foundation, Stichting Benchmark GGZ (mental health care), in which GGZ Nederland has participated since 2010. ROM provides therapists with a means for improving treatment and provides insurers with a means by which they can express their views about the quality of the mental health services at aggregate level.

Wind-Friendly Flexible Ramping Product Design in Multi-Timescale Power System Operations

With increasing wind power penetration in the electricity grid, system operators are recognizing the need for additional flexibility, and some are implementing new ramping products as a type of ancillary service. However, wind is generally thought of as causing the need for ramping services, not as being a potential source for the service. In this paper, a multi-timescale unit commitment and economic dispatch model is developed to consider the wind power ramping product (WPRP). An optimized swinging door algorithm with dynamic programming is applied to identify and forecast wind power ramps (WPRs). Designed as positive characteristics of WPRs, the WPRPmore » is then integrated into the multi-timescale dispatch model that considers new objective functions, ramping capacity limits, active power limits, and flexible ramping requirements. Numerical simulations on the modified IEEE 118-bus system show the potential effectiveness of WPRP in increasing the economic efficiency of power system operations with high levels of wind power penetration. It is found that WPRP not only reduces the production cost by using less ramping reserves scheduled by conventional generators, but also possibly enhances the reliability of power system operations. Moreover, wind power forecasts play an important role in providing high-quality WPRP service.« less

Cardiopulmonary resuscitation (CPR) performed by bystanders is associated with increased survival rates among persons with out-of-hospital cardiac arrest. We investigated whether rates of bystander-initiated CPR could be increased with the use of a mobile-phone positioning system that could instantly locate mobile-phone users and dispatch lay volunteers who were trained in CPR to a patient nearby with out-of-hospital cardiac arrest. We conducted a blinded, randomized, controlled trial in Stockholm from April 2012 through December 2013. A mobile-phone positioning system that was activated when ambulance, fire, and police services were dispatched was used to locate trained volunteers who were within 500 m of patients with out-of-hospital cardiac arrest; volunteers were then dispatched to the patients (the intervention group) or not dispatched to them (the control group). The primary outcome was bystander-initiated CPR before the arrival of ambulance, fire, and police services. A total of 5989 lay volunteers who were trained in CPR were recruited initially, and overall 9828 were recruited during the study. The mobile-phone positioning system was activated in 667 out-of-hospital cardiac arrests: 46% (306 patients) in the intervention group and 54% (361 patients) in the control group. The rate of bystander-initiated CPR was 62% (188 of 305 patients) in the intervention group and 48% (172 of 360 patients) in the control group (absolute difference for intervention vs. control, 14 percentage points; 95% confidence interval, 6 to 21; P<0.001). A mobile-phone positioning system to dispatch lay volunteers who were trained in CPR was associated with significantly increased rates of bystander-initiated CPR among persons with out-of-hospital cardiac arrest.

Building resilience of the Global Positioning System to space weather

NASA Astrophysics Data System (ADS)

Fisher, Genene; Kunches, Joseph

2011-12-01

Almost every aspect of the global economy now depends on GPS. Worldwide, nations are working to create a robust Global Navigation Satellite System (GNSS), which will provide global positioning, navigation, and timing (PNT) services for applications such as aviation, electric power distribution, financial exchange, maritime navigation, and emergency management. The U.S. government is examining the vulnerabilities of GPS, and it is well known that space weather events, such as geomagnetic storms, contribute to errors in single-frequency GPS and are a significant factor for differential GPS. The GPS industry has lately begun to recognize that total electron content (TEC) signal delays, ionospheric scintillation, and solar radio bursts can also interfere with daily operations and that these threats grow with the approach of the next solar maximum, expected to occur in 2013. The key challenges raised by these circumstances are, first, to better understand the vulnerability of GPS technologies and services to space weather and, second, to develop policies that will build resilience and mitigate risk.

Sunarti, T.; Wasis; Madlazim; Suyidno; Prahani, B. K.

2018-03-01

In the previous research, learning material based Construction, Production, and Implementation (CPI) model has been developed to improve scientific literacy and positive attitude toward science for pre-service physics teacher. CPI model has 4 phases, included: 1) Motivation; 2) Construction (Cycle I); 3) Production (Cycle II); and 4) Evaluation. This research is aimed to analyze the effectiveness of CPI model towards the improvement Positive Attitude toward Science (PATS) for pre-service physics teacher. This research used one group pre-test and post-test design on 160 pre-service physics teacher divided into 4 groups at Lambung Mangkurat University and Surabaya State University (Indonesia), academic year 2016/2017. Data collection was conducted through questioner, observation, and interview. Positive attitude toward science for pre-service physics teacher measurement were conducted through Positive Attitude toward Science Evaluation Sheet (PATSES). The data analysis technique was done by using Wilcoxon test and n-gain. The results showed that there was a significant increase in positive attitude toward science for pre-service physics teacher at α = 5%, with n-gain average of high category. Thus, the CPI model is effective for improving positive attitude toward science for pre-service physics teacher.

A Leapfrog Navigation System

NASA Astrophysics Data System (ADS)

Opshaug, Guttorm Ringstad

There are times and places where conventional navigation systems, such as the Global Positioning System (GPS), are unavailable due to anything from temporary signal occultations to lack of navigation system infrastructure altogether. The goal of the Leapfrog Navigation System (LNS) is to provide localized positioning services for such cases. The concept behind leapfrog navigation is to advance a group of navigation units teamwise into an area of interest. In a practical 2-D case, leapfrogging assumes known initial positions of at least two currently stationary navigation units. Two or more mobile units can then start to advance into the area of interest. The positions of the mobiles are constantly being calculated based on cross-range distance measurements to the stationary units, as well as cross-ranges among the mobiles themselves. At some point the mobile units stop, and the stationary units are released to move. This second team of units (now mobile) can then overtake the first team (now stationary) and travel even further towards the common goal of the group. Since there always is one stationary team, the position of any unit can be referenced back to the initial positions. Thus, LNS provides absolute positioning. I developed navigation algorithms needed to solve leapfrog positions based on cross-range measurements. I used statistical tools to predict how position errors would grow as a function of navigation unit geometry, cross-range measurement accuracy and previous position errors. Using this knowledge I predicted that a 4-unit Leapfrog Navigation System using 100 m baselines and 200 m leap distances could travel almost 15 km before accumulating absolute position errors of 10 m (1sigma). Finally, I built a prototype leapfrog navigation system using 4 GPS transceiver ranging units. I placed the 4 units in the vertices a 10m x 10m square, and leapfrogged the group 20 meters forwards, and then back again (40 m total travel). Average horizontal RMS position errors never exceeded 16 cm during these field tests.

Reforming the Greek health system: a role for non-medical, clinical bioscientists.

PubMed

Kazanis, Ilias

2013-01-01

Within the context of the recent debt crisis and the subsequently adopted austerity measures, the Greek health system faces important challenges including the necessity to rationalize public spending. One domain where there is scope for reducing expenses is laboratory medicine services, that are provided by both public and private facilities. Specialized non-medical, clinical bioscientists (such as molecular biologists, biochemists and geneticists) massively participate in the provision of laboratory medicine services in both sectors; however, they are excluded from key positions, such as the direction of laboratories and sitting in regulatory bodies. This is in breach with European standards of practice and also constitutes an impediment to the much anticipated rationalization of spending; therefore has to be addressed by the Greek health services authorities.

Through the use of ubiquitous health, or u-Health, services, medical information can be adapted and made accessible via computer and Internet to provide quality healthcare to anybody, any place, and any time. We developed and implemented u-Health services for patients with chronic obstructive pulmonary disease and studied their experiences with respect to their knowledge of chronic obstructive pulmonary disease and skill and attitude toward the u-Health devices. The u-Health services were composed of telemonitoring and teleconsultation supplemented with home visits. To determine its effectiveness, the u-Health service system was implemented for 2 years with 144 chronic obstructive pulmonary disease patients in a clinical experiment. The subjects were divided into three experimental groups, each provided with different services, compared before and after intervention, and among groups. The analysis of data gathered through the system suggested that u-Health services can support patients with chronic obstructive pulmonary disease, improve patients' knowledge about chronic obstructive pulmonary disease self-management, build u-Health device usage skills, and foster a positive attitude toward u-Health devices. The u-Health services for the chronic obstructive pulmonary disease patients were both feasible and effective from the patients' perspective.

Prevention of new HIV infections is a critical imperative for South Africa; the prevention of mother-to-child transmission (PMTCT) is one of the most efficacious HIV prevention interventions. Assessment of a PMTCT programme to determine missed opportunities. The Kouga local service area (LSA), bordering Nelson Mandela Bay Municipality (Port Elizabeth) in the Eastern Cape. An assessment was conducted in 2007 before implementing technical support for strengthening the PMTCT programme, including: interviews with 20 PMTCT managers, 4 maternity staff and 27 other health workers on service provision, management, infrastructure, human resources and the health information system; 296 antenatal clinic users on their service perceptions; 70 HIV-positive women on HIV knowledge, infant feeding, coping, support and service perceptions; 8 representatives from community organisations and 101 traditional health practitioners (THPs). Observations were conducted during site visits to health facilities, and the District Health Information System (DHIS) data were reviewed. Staff had high levels of awareness of HIV policies and most had received some relevant training. Nevirapine uptake varied by clinic, with an average of 56%. There were many missed opportunities for PMTCT, with 67% of pregnant women tested for HIV and only 43% of antenatal care attendees tested during a previous pregnancy. Only 6% of HIV-positive women reported support group participation. Reducing missed opportunities for PMTCT requires strengthening of the formal health sector, intersectoral liaison, and greater community support. Priority areas that require strengthening in the formal health sector include HIV counselling and testing; family planning and nutrition counselling; infant follow-up; human resources; and monitoring and evaluation.

As Mars exploration grows in complexity with time, the corresponding communication needs will grow in variety and complexity also. From initial Earth/Mars links, further needs will arise for complete surface connectivity for the provision of navigation, position location, and voice, data, and video communications services among multiple Mars bases and remote exploration sites. This paper addresses the likely required communication functions over the first few decades of Martian exploration and postulates systems for providing these services. Required technologies are identified and development requirements indicated.

Enhacements to the TTS-502 time transfer system

NASA Astrophysics Data System (ADS)

Vandierendonck, A. J.; Hua, Q. D.

1985-04-01

Two years ago STI introduced an affordable, relatively compact time transfer system on the market -- the TTS-502, and described that system at the 1981 PTTI conference. Over the past few months, that system has been improved, and new features have been added. In addition, new options have been made available to further enhance the capabilities of the system. These enhancements include the addition of a positioning algorithm and new options providing a corrected 5 MHz output that is phase coherent with the 1 pps output, and providing an internal Rubidium Oscillator. The Positioning Algorithm was developed because not all time transfer users had the luxury of the Defense Mapping Agency's (DMA) services for determining their position in WGS-72 coordinates. The enhanced TTS-502 determines the GPS position anywhere in the world, independent of how many GPS satellites are concurrently visible. However, convergence time to a solution is inversely proportional to the number of satellites concurrently visible and the quality of frequency standard used in conjunction with the TTS-502. Real World solution results will be presented for a variety of cases and satellite scheduling scenarios. Typically, positioning accuracies were achieved better than 5 to 10 meters r.s.s. using the C/A code only at Sunnyvale, California.

A Review of Wearable Technologies for Elderly Care that Can Accurately Track Indoor Position, Recognize Physical Activities and Monitor Vital Signs in Real Time

Rapid growth of the aged population has caused an immense increase in the demand for healthcare services. Generally, the elderly are more prone to health problems compared to other age groups. With effective monitoring and alarm systems, the adverse effects of unpredictable events such as sudden illnesses, falls, and so on can be ameliorated to some extent. Recently, advances in wearable and sensor technologies have improved the prospects of these service systems for assisting elderly people. In this article, we review state-of-the-art wearable technologies that can be used for elderly care. These technologies are categorized into three types: indoor positioning, activity recognition and real time vital sign monitoring. Positioning is the process of accurate localization and is particularly important for elderly people so that they can be found in a timely manner. Activity recognition not only helps ensure that sudden events (e.g., falls) will raise alarms but also functions as a feasible way to guide people’s activities so that they avoid dangerous behaviors. Since most elderly people suffer from age-related problems, some vital signs that can be monitored comfortably and continuously via existing techniques are also summarized. Finally, we discussed a series of considerations and future trends with regard to the construction of “smart clothing” system. PMID:28208620

Johnson, Jay Tillay

For three years, Sandia National Laboratories, Georgia Institute of Technology, and University of Illinois at Urbana-Champaign investigated a smart grid vision in which renewable-centric Virtual Power Plants (VPPs) provided ancillary services with interoperable distributed energy resources (DER). This team researched, designed, built, and evaluated real-time VPP designs incorporating DER forecasting, stochastic optimization, controls, and cyber security to construct a system capable of delivering reliable ancillary services, which have been traditionally provided by large power plants or other dedicated equipment. VPPs have become possible through an evolving landscape of state and national interconnection standards, which now require DER to include grid-supportmore » functionality and communications capabilities. This makes it possible for third party aggregators to provide a range of critical grid services such as voltage regulation, frequency regulation, and contingency reserves to grid operators. This paradigm (a) enables renewable energy, demand response, and energy storage to participate in grid operations and provide grid services, (b) improves grid reliability by providing additional operating reserves for utilities, independent system operators (ISOs), and regional transmission organization (RTOs), and (c) removes renewable energy high-penetration barriers by providing services with photovoltaics and wind resources that traditionally were the jobs of thermal generators. Therefore, it is believed VPP deployment will have far-reaching positive consequences for grid operations and may provide a robust pathway to high penetrations of renewables on US power systems. In this report, we design VPPs to provide a range of grid-support services and demonstrate one VPP which simultaneously provides bulk-system energy and ancillary reserves.« less

INTRODUCTION OF UNIVERSAL HEALTH PROGRAM IN GEORGIA: PROBLEMS AND PERSPECTIVES.

Verulava, T; Jorbenadze, R; Barkalaia, T

2017-01-01

Since 2013, Georgia enacted Universal Healthcare (UHC) program. Inclusion of uninsured population in the UHC program will have a positive impact on their financial accessibility to the health services. The study aims to analyze the referral rate of the beneficiaries to the health service providers before introduction and after application of the UHC program, particularly, how much it increased the recently uninsured population referral to primary health care units, and also to study the level of satisfaction with the UHC program. Research was conducted by qualitative and quantitative methods. The target groups' (program beneficiaries, physicians, personnel of the Social Service Agency) opinions were identified by means of face-to-face interviews. Enactment of the UHC programs significantly raised the population refferal to the family physicians, and the specialists. Insignificantly, but also increased the frequency of laboratory and diagnostic services. Despite the serious positive changes caused by UHC program implementation there still remain the problems in the primary healthcare system. Also, it is desirable to raise the financial availability of those medical services, which may cause catastrophic costs. In this respect, such medical services must be involved in the universal healthcare program and been expanded their scale. For the purpose of effective usage of the limited funds allocated for health care services provision, the private health insurance companies should be involved in UHC programs. This, together with the reduction of health care costs will increase a competition in the medical market, and enhance the quality of health service.

Evaluating the success of an emergency response medical information system.

Petter, Stacie; Fruhling, Ann

STATPack™ is an information system used to aid in the diagnosis of pathogens in hospitals and state public health laboratories. STATPack™ is used as a communication and telemedicine diagnosis tool during emergencies. This paper explores the success of this emergency response medical information system (ERMIS) using a well-known framework of information systems success developed by DeLone and McLean. Using an online survey, the entire population of STATPack™ users evaluated the success of the information system by considering system quality, information quality, system use, intention to use, user satisfaction, individual impact, and organizational impact. The results indicate that the overall quality of this ERMIS (i.e., system quality, information quality, and service quality) has a positive impact on both user satisfaction and intention to use the system. However, given the nature of ERMIS, overall quality does not necessarily predict use of the system. Moreover, the user's satisfaction with the information system positively affected the intention to use the system. User satisfaction, intention to use, and system use had a positive influence on the system's impact on the individual. Finally, the organizational impacts of the system were positively influenced by use of the system and the system's individual impact on the user. The results of the study demonstrate how to evaluate the success of an ERMIS as well as introduce potential changes in how one applies the DeLone and McLean success model in an emergency response medical information system context.

We have conducted a study on the long-term availability of bioinformatics Web services: an observation of 927 Web services published in the annual Nucleic Acids Research Web Server Issues between 2003 and 2009. We found that 72% of Web sites are still available at the published addresses, only 9% of services are completely unavailable. Older addresses often redirect to new pages. We checked the functionality of all available services: for 33%, we could not test functionality because there was no example data or a related problem; 13% were truly no longer working as expected; we could positively confirm functionality only for 45% of all services. Additionally, we conducted a survey among 872 Web Server Issue corresponding authors; 274 replied. 78% of all respondents indicate their services have been developed solely by students and researchers without a permanent position. Consequently, these services are in danger of falling into disrepair after the original developers move to another institution, and indeed, for 24% of services, there is no plan for maintenance, according to the respondents. We introduce a Web service quality scoring system that correlates with the number of citations: services with a high score are cited 1.8 times more often than low-scoring services. We have identified key characteristics that are predictive of a service's survival, providing reviewers, editors, and Web service developers with the means to assess or improve Web services. A Web service conforming to these criteria receives more citations and provides more reliable service for its users. The most effective way of ensuring continued access to a service is a persistent Web address, offered either by the publishing journal, or created on the authors' own initiative, for example at http://bioweb.me. The community would benefit the most from a policy requiring any source code needed to reproduce results to be deposited in a public repository.

We checked the functionality of all available services: for 33%, we could not test functionality because there was no example data or a related problem; 13% were truly no longer working as expected; we could positively confirm functionality only for 45% of all services. Additionally, we conducted a survey among 872 Web Server Issue corresponding authors; 274 replied. 78% of all respondents indicate their services have been developed solely by students and researchers without a permanent position. Consequently, these services are in danger of falling into disrepair after the original developers move to another institution, and indeed, for 24% of services, there is no plan for maintenance, according to the respondents. We introduce a Web service quality scoring system that correlates with the number of citations: services with a high score are cited 1.8 times more often than low-scoring services. We have identified key characteristics that are predictive of a service's survival, providing reviewers, editors, and Web service developers with the means to assess or improve Web services. A Web service conforming to these criteria receives more citations and provides more reliable service for its users. The most effective way of ensuring continued access to a service is a persistent Web address, offered either by the publishing journal, or created on the authors' own initiative, for example at http://bioweb.me. The community would benefit the most from a policy requiring any source code needed to reproduce results to be deposited in a public repository. PMID:21966383

2013-04-01

China has been developing its own independent satellite navigation system since decades. Now the COMPASS system, also known as BeiDou, is emerging and gaining more and more interest and attention in the worldwide GNSS communities. The current regional BeiDou system is ready for its operational service around the end of 2012 with a constellation including five Geostationary Earth Orbit satellites (GEO), five Inclined Geosynchronous Orbit satellites (IGSO) and four Medium Earth orbit (MEO) satellites in operation. Besides the open service with positioning accuracy of around 10m which is free to civilian users, both precise relative positioning, and precise point positioning are demonstrated as well. In order to enhance the BeiDou precise positioning service, Precise Orbit Determination (POD) which is essential of any satellite navigation system has been investigated and studied thoroughly. To further improving the orbits of different types of satellites, we study the impact of network coverage on POD data products by comparing results from tracking networks over the Chinese territory, Asian-Pacific, Asian and of global scale. Furthermore, we concentrate on the improvement of involving MEOs on the orbit quality of GEOs and IGSOs. POD with and without MEOs are undertaken and results are analyzed. Finally, integer ambiguity resolution which brings highly improvement on orbits and positions with GPS data is also carried out and its effect on POD data products is assessed and discussed in detail. Seven weeks of BeiDou data from a ground tracking network, deployed by Wuhan University is employed in this study. The test constellation includes four GEO, five IGSO and two MEO satellites in operation. The three-day solution approach is employed to enhance its strength due to the limited coverage of the tracking network and the small movement of most of the satellites. A number of tracking scenarios and processing schemas are identified and processed and overlapping orbit differences are utilized to qualify the estimated orbits and clocks. The results show that GEO orbits, especially the along-track component, can be significantly improved by extending the tracking network in China along longitude direction, whereas IGSOs gain more improvement if the tracking network extends in latitude. For the current tracking network, deploying tracking stations on the eastern side, for example in New Zealand and/or in Hawaii, will significantly reduce along-track biases of GEOs on the same side. The involvement of MEOs and ambiguity-fixing also make the orbits better but rather moderate. Key words: BeiDou, precise orbit determination (POD), tracking network, ambiguity-fixing

Benefits from the modernized US Global Positioning System (GPS), the revitalized Russian GLObal NAvigation Satellite System (GLONASS), and the newly-developed Chinese BeiDou Navigation Satellite System (BDS) and European Galileo, multi-constellation Global Navigation Satellite System (GNSS) has emerged as a powerful tool not only in positioning, navigation, and timing (PNT), but also in remote sensing of the atmosphere and ionosphere. Both precise positioning and the derivation of atmospheric parameters can benefit from multi-GNSS observations. In this contribution, extensive evaluations are conducted with multi-GNSS datasets collected from 134 globally-distributed ground stations of the International GNSS Service (IGS) Multi-GNSS Experiment (MGEX) network in July 2016. The datasets are processed in six different constellation combinations, i.e., GPS-, GLONASS-, BDS-only, GPS + GLONASS, GPS + BDS, and GPS + GLONASS + BDS + Galileo precise point positioning (PPP). Tropospheric gradients are estimated with eight different temporal resolutions, from 1 h to 24 h, to investigate the impact of estimating high-resolution gradients on position estimates. The standard deviation (STD) is used as an indicator of positioning repeatability. The results show that estimating tropospheric gradients with high temporal resolution can achieve better positioning performance than the traditional strategy in which tropospheric gradients are estimated on a daily basis. Moreover, the impact of estimating tropospheric gradients with different temporal resolutions at various elevation cutoff angles (from 3° to 20°) is investigated. It can be observed that with increasing elevation cutoff angles, the improvement in positioning repeatability is decreased. PMID:28368346

A mobile interactive online health system was used to conduct virtual ward rounds at a regional hospital which had no specialist paediatrician. The system was wireless, which allowed telepaediatric services to be delivered direct to the bedside. Between December 2004 and May 2005, 43 virtual ward rounds were coordinated between specialists based in Brisbane and local staff at the Gladstone Hospital. Eighty-six consultations were provided for 64 patients. The most common conditions included asthma (27%), chest infections (12%), gastroenteritis (10%) and urinary tract infections (10%). In the majority of cases, there were partial (67%) or complete changes (11%) in the clinical management of patients. Specialist services were offered by a team of 13 clinicians at the Royal Children's Hospital: 10 general paediatricians, two physiotherapists and one registered nurse. Feedback from all consultants involved in the service and local staff in Gladstone was extremely positive. In 43 videoconference calls there were three technical problems, probably due to an intermittent mains power supply at the regional hospital. There appears to be potential for other rural and regional hospitals to adopt this model of service delivery.

Access to oral health care for people living with HIV/AIDS is a severe problem. This article describes the design and impact of an Innovations in Oral Health Care Initiative program, funded through the Health Resources and Services Administration HIV/AIDS Bureau's Special Projects of National Significance (SPNS) program, that expanded oral health-care services for these individuals in rural Oregon. From April 2007 to August 2010, 473 patients received dental care (exceeding the target goal of 410 patients) and 153 dental hygiene students were trained to deliver oral health care to HIV-positive patients. The proportion of patients receiving oral health care increased from 10% to 65%, while the no-show rate declined from 40% to 10%. Key implementation components were leveraging SPNS funding and services to create an integrated delivery system, collaborations that resulted in improved service delivery systems, using dental hygiene students to deliver oral health care, enhanced care coordination through the services of a dental case manager, and program capacity to adjust to unanticipated needs.

The work of a family physician is quite different in each country, and if we consider different continents, differences are even more remarkable. Social and cultural contexts justify a particular organization, not only of the health-care system but also its providers as well. By analyzing different health-care systems, new ideas may come about which may trigger positive changes in a health-care service to diminish healthcare disparities. Description and comparison of the Primary Healthcare Service in Canada and Portugal. Although both health-care systems are mainly public, organizational differences can be found that condition primary healthcare access. Exchanges in other health-care systems contribute for an active knowledge exchange that prompts participants to analyze options on how to improve healthcare access to citizens. This ultimately, leads to the development of primary care, the pillar of a well-functioning health-care system.

A Comparative Study of Precise Point Positioning (PPP) Accuracy Using Online Services

NASA Astrophysics Data System (ADS)

Malinowski, Marcin; Kwiecień, Janusz

2016-12-01

Precise Point Positioning (PPP) is a technique used to determine the position of receiver antenna without communication with the reference station. It may be an alternative solution to differential measurements, where maintaining a connection with a single RTK station or a regional network of reference stations RTN is necessary. This situation is especially common in areas with poorly developed infrastructure of ground stations. A lot of research conducted so far on the use of the PPP technique has been concerned about the development of entire day observation sessions. However, this paper presents the results of a comparative analysis of accuracy of absolute determination of position from observations which last between 1 to 7 hours with the use of four permanent services which execute calculations with PPP technique such as: Automatic Precise Positioning Service (APPS), Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP), GNSS Analysis and Positioning Software (GAPS) and magicPPP - Precise Point Positioning Solution (magicGNSS). On the basis of acquired results of measurements, it can be concluded that at least two-hour long measurements allow acquiring an absolute position with an accuracy of 2-4 cm. An evaluation of the impact on the accuracy of simultaneous positioning of three points test network on the change of the horizontal distance and the relative height difference between measured triangle vertices was also conducted. Distances and relative height differences between points of the triangular test network measured with a laser station Leica TDRA6000 were adopted as references. The analyses of results show that at least two hours long measurement sessions can be used to determine the horizontal distance or the difference in height with an accuracy of 1-2 cm. Rapid products employed in calculations conducted with PPP technique reached the accuracy of determining coordinates on a close level as in elaborations which employ Final products.

Fielding, Jonathan E; Luck, Jeff; Tye, Grace

2003-01-01

In 1997, the Los Angeles County Department of Health Services launched an effort to revitalize its Public Health Services division. County investments resulted in the creation of 241 new positions, facilitating the establishment of new offices addressing neglected chronic disease prevention, staff development, training, and communication. Service effectiveness and community responsiveness were enhanced by decentralizing leadership through eight Area Health Offices and strengthening partnerships with private health care providers, community-based organizations, and managed care organizations. Infrastructure enhancements included the development of program performance measures, countywide health indicators, a central health assessment and epidemiology office, and a new countywide biennial survey.

Equitable access to elective hospital services: the introduction of patient choice in a decentralised healthcare system.

PubMed

Ringard, Ånen

2012-02-01

During the 1980s and 1990s, increased waiting times for elective surgery was perceived to be a major accessibility problem in many countries. In an attempt to improve access, hospital choice reforms were introduced in a number of countries. In Norway, a nationwide reform to improve access came into effect in 2001. At the same time, renewed support was expressed for the long-standing political aim of ensuring equal access to healthcare services for all citizens regardless of their social position. The current aim is to analyse the relationship of the hospital choice reform and the goal of equitable access to hospital services. A survey conducted among Norwegian patients in 2004 provided information about whether a choice of hospital had been made. Information from the survey was merged with administrative data from the hospital that performed the treatment. The survey provided data on patients' socioeconomic position. Demographics, medical need, and prior use of healthcare services were controlled for to determine the effect of socioeconomic position on hospital choice. The patient's socioeconomic position, measured by education, was found to be significantly associated with hospital choice. The relationship resembled that of a social gradient. Patients with a primary education were less likely to have made a choice, followed by those with secondary education or a lower university degree. Patients with higher university education were most likely to have chosen. Hospital selection is a demanding task for many patients. Policymakers should therefore focus on crafting and implementing tools necessary for supporting uptake of choice in disadvantaged groups.

The statistics related to labor accidents as with any other notification system ought to be the basis for programs and policies with a view to the adoption of preventive measures. In order to establish preventive norms, however, the health system needs data from researchers focussing on the dynamics of and the pitfalls revealed by specific events. Within this context the main objective of this study is to proceed with an in-depth analysis of the labor accidents verified in Barcelona (Spain) using for this purpose a descriptive statistics model to test variables such as type of accident, economic sector, economic enterprise and type of labor contract. The data source utilized was the notification system for labor accidents with grave consequences such as death of the victim registered in Barcelona during the period 1992-1993. Labor accidents registered for male workers numbered 848. A log-linear model was applied to this data base. The results show a positive association between traumatic accidents with the construction, traffic and services sectors. A positive association was also found between traumatic accidents and the size of the company concerved the small ones being the worse type in terms of worker's injuries. Regarding the nontraumatic accidents, the study showed a positive correlation between large-sized enterprises and type of temporary worker and the civil construction sector as compared to workers with long term work contracts within industry and services. There was some evidence, also, of a positive association between small and medium sized companies and temporary work and the occurrence of work accidents.

Asteroids Search Results in Large Photographic Sky Surveys

Shatokhina, S. V.; Kazantseva, L. V.; Yizhakevych, O. M.; Eglitis, I.; Andruk, V. M.

Photographic observations of XX century contained numerous and varied information about all objects and events of the Universe fixed on plates. The original and interesting observations of small bodies of the Solar system in previous years can be selected and used for various scientific tasks. Existing databases and online services can help make such selection easily and quickly. The observations of chronologically earlier ppositions, photometric evaluation of brightness for long periods of time allow refining the orbits of asteroids and identifying various non-stationaries. Photographic observations of Northern Sky Survey project and observations of clusters in UBVR bands were used for global search for small bodies of Solar system. Total we founded 2486 positions of asteroids and 13 positions of comets. All positions were compared with ephemeris. It was found that 80 positions of asteroids have a moment of observation preceding their discovery, and 19 of them are chronologically the earliest observations of these asteroids in the world.

Kinematic-PPP using Single/Dual Frequency Observations from (GPS, GLONASS and GPS/GLONASS) Constellations for Hydrography

NASA Astrophysics Data System (ADS)

Farah, Ashraf

2018-03-01

Global Positioning System (GPS) technology is ideally suited for inshore and offshore positioning because of its high accuracy and the short observation time required for a position fix. Precise point positioning (PPP) is a technique used for position computation with a high accuracy using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be acquired from different sources such as the International GNSS Service (IGS). PPP precision varies based on positioning technique (static or kinematic), observations type (single or dual frequency) and the duration of observations among other factors. PPP offers comparable accuracy to differential GPS with safe in cost and time. For many years, PPP users depended on GPS (American system) which considered the solely reliable system. GLONASS's contribution in PPP techniques was limited due to fail in maintaining full constellation. Yet, GLONASS limited observations could be integrated into GPS-based PPP to improve availability and precision. As GLONASS reached its full constellation early 2013, there is a wide interest in PPP systems based on GLONASS only and independent of GPS. This paper investigates the performance of kinematic PPP solution for the hydrographic applications in the Nile river (Aswan, Egypt) based on GPS, GLONASS and GPS/GLONASS constellations. The study investigates also the effect of using two different observation types; single-frequency and dual frequency observations from the tested constellations.

2016-01-01

Objective With the use of a qualitative approach, this study focuses on service providers’ experiences and perspectives on recovery-oriented reform. Methods Nine focus groups were conducted with a sample of 68 service providers recruited from three Canadian sites. Results Three major themes were identified: 1) positive attitudes towards recovery-oriented reform; 2) skepticism towards recovery-oriented reform; and 3) challenges associated with implementing recovery-oriented practice. These challenges pertained to conceptual uncertainty and consistency around the meanings of recovery; application of recovery-oriented practice with certain populations and in certain contexts; bureaucratization of recovery-oriented tools; limited leadership support; and, societal stigma and social exclusion of persons with mental illnesses. Conclusions and Implications for Practice The findings point towards challenges that might arise as system planners move ahead in their efforts toward implementing recovery within the mental health system. In this regard, we offer several recommendations for the planning of organizational and educational practices that support the implementation of recovery-oriented practice. PMID:22491368

A service is described that makes possible the effective construction of a three-dimensional ionospheric model based on the data of ground receivers of signals from global navigation satellite positioning systems (GNSS). The obtained image has a high resolution, mainly because data from the IPG GNSS network of the Federal Service for Hydrometeorology and Environmental Monitoring (Rosgidromet) are used. A specially developed format and its implementation in the form of SQL structures are used to collect, transmit, and store data. The method of high-altitude radio tomography is used to construct the three-dimensional model. The operation of all system components (from registration point organization to the procedure for constructing the electron density three-dimensional distribution and publication of the total electron content map on the Internet) has been described in detail. The three-dimensional image of the ionosphere, obtained automatically, is compared with the ionosonde measurements, calculated using the two-dimensional low-altitude tomography method and averaged by the ionospheric model.

Contextualizing emotional exhaustion and positive emotional display: the signaling effects of supervisors' emotional exhaustion and service climate.

PubMed

Lam, Catherine K; Huang, Xu; Janssen, Onne

2010-03-01

In this study, we investigated how supervisors' emotional exhaustion and service climate jointly influence the relationship between subordinates' emotional exhaustion and their display of positive emotions at work. Using data from frontline sales employees and their immediate supervisors in a fashion retailer, we hypothesized and found that under the condition of a less positive service climate, subordinates' emotional exhaustion was more negatively related to their positive emotional display when supervisors' emotional exhaustion was higher rather than lower; this interaction effect of subordinates' and supervisors' emotional exhaustion was not significant in a more positive service climate. These results suggest that service climate and supervisors' emotional exhaustion provide emotionally exhausted employees with important information cues about the possible availability of compensatory resources they need to uphold their efforts to display service-focused emotions. 2010 APA, all rights reserved

Indoor/Outdoor Seamless Positioning Using Lighting Tags and GPS Cellular Phones for Personal Navigation

NASA Astrophysics Data System (ADS)

Namie, Hiromune; Morishita, Hisashi

The authors focused on the development of an indoor positioning system which is easy to use, portable and available for everyone. This system is capable of providing the correct position anywhere indoors, including onboard ships, and was invented in order to evaluate the availability of GPS indoors. Although the performance of GPS is superior outdoors, there has been considerable research regarding indoor GPS involving sensitive GPS, pseudolites (GPS pseudo satellite), RFID (Radio Frequency IDentification) tags, and wireless LAN .However, the positioning rate and the precision are not high enough for general use, which is the reason why these technologies have not yet spread to personal navigation systems. In this regard, the authors attempted to implement an indoor positioning system using cellular phones with built-in GPS and infrared light data communication functionality, which are widely used in Japan. GPS is becoming increasingly popular, where GPGGS sentences of the NMEA outputted from the GPS receiver provide spatiotemporal information including latitude, longitude, altitude, and time or ECEF xyz coordinates. As GPS applications grow rapidly, spatiotemporal data becomes key to the ubiquitous outdoor and indoor seamless positioning services at least for the entire area of Japan, as well as to becoming familiar with satellite positioning systems (e.g. GPS). Furthermore, the authors are also working on the idea of using PDAs (Personal Digital Assistants), as cellular phones with built-in GPS and PDA functionality are also becoming increasingly popular.

Mental health problems are disproportionately represented in the community corrections system with limited information on the epidemiology of mental health and correlated factors such as suicide among probationers. This study recruited 2,077 probationers who completed screeners for mental health and substance disorders and suicide risk. Results found 13% of probationers were at high risk of suicide. Those who screened positive for a mental health condition were between 2 and 8 times more likely to screen positive for suicide risk. Allocation of additional resources to mental health in the criminal justice system and to effectively coordinate existing mental health services is needed.

Positive parenting programs, developmental support services, and evidence-based home visiting programs can effectively provide parenting support and improve health and developmental outcomes for at-risk children. Few models, however, have integrated referrals for on-site support and home visiting programs into the provision of routine pediatric care within a medical home. This article describes an innovative approach, through partnership with a community-based organization, to deliver on-site and home visiting support services for children and families within and beyond the medical home. Our model offers a system of on-site services, including parenting, behavior, and/or development support, with optional intensive home visiting services. Assessment included description of the population served, delineation of services provided, and qualitative identification of key themes of the impact of services, illustrated by case examples. This replicable model describes untapped potential of the pediatric medical home as a springboard to mitigate risk and optimize children's health and development.

2018-03-30

We explored relationships of school-based physical therapy to standardized outcomes of students receiving physical therapy. Using a practice-based evidence research design, School Function Assessment (SFA) outcomes of 296 students with disabilities (mean age 7y 4mo [standard deviation 2y]; 166 males, 130 females), served by 109 physical therapists, were explored. After training, therapists completed 10 SFA scales on students at the beginning and end of the school year. Therapists collected detailed weekly data on services (activities, interventions, types, student participation) using the School-Physical Therapy Interventions for Pediatrics (S-PTIP) system. Stepwise linear regressions were used to investigate S-PTIP predictors of SFA outcomes. Predictors of SFA section outcomes varied in strength, with the coefficient of determination (R 2 ) for each outcome ranging from 0.107 to 0.326. Services that correlated positively with the SFA outcomes included mobility, sensory, motor learning, aerobic/conditioning, functional strengthening, playground access interventions, and higher student participation during therapy (standardized β=0.11-0.26). Services that correlated negatively with the SFA outcomes included providing services within student groups, within school activity, with students not in special education, during recreation activities, and with positioning, hands-on facilitation, sensory integration, orthoses, and equipment interventions (standardized β=-0.14 to -0.22). Consideration of outcomes is prudent to focus services. Overall results suggest we should emphasize active mobility practice by using motor learning interventions and engaging students within therapy sessions. No specific interventions predicted positively on all School Function Assessment (SFA) outcomes. Active movement practice seems related to overall better SFA outcomes. Active mobility practice improved SFA participation, mobility, recreation, and activities of daily living. Engaging students in therapy activities and interventions improved outcomes. © 2018 Mac Keith Press.

The protective role of coastal marshes: a systematic review and meta-analysis.

PubMed

Shepard, Christine C; Crain, Caitlin M; Beck, Michael W

2011-01-01

Salt marshes lie between many human communities and the coast and have been presumed to protect these communities from coastal hazards by providing important ecosystem services. However, previous characterizations of these ecosystem services have typically been based on a small number of historical studies, and the consistency and extent to which marshes provide these services has not been investigated. Here, we review the current evidence for the specific processes of wave attenuation, shoreline stabilization and floodwater attenuation to determine if and under what conditions salt marshes offer these coastal protection services. We conducted a thorough search and synthesis of the literature with reference to these processes. Seventy-five publications met our selection criteria, and we conducted meta-analyses for publications with sufficient data available for quantitative analysis. We found that combined across all studies (n = 7), salt marsh vegetation had a significant positive effect on wave attenuation as measured by reductions in wave height per unit distance across marsh vegetation. Salt marsh vegetation also had a significant positive effect on shoreline stabilization as measured by accretion, lateral erosion reduction, and marsh surface elevation change (n = 30). Salt marsh characteristics that were positively correlated to both wave attenuation and shoreline stabilization were vegetation density, biomass production, and marsh size. Although we could not find studies quantitatively evaluating floodwater attenuation within salt marshes, there are several studies noting the negative effects of wetland alteration on water quantity regulation within coastal areas. Our results show that salt marshes have value for coastal hazard mitigation and climate change adaptation. Because we do not yet fully understand the magnitude of this value, we propose that decision makers employ natural systems to maximize the benefits and ecosystem services provided by salt marshes and exercise caution when making decisions that erode these services.

This study assessed the prevalence of exchanging sex for money or drugs among men who have sex with men (MSM) in the 2011 US National HIV Behavioral Surveillance system. Prevalence of HIV, being HIV-positive but unaware (HIV-positive-unaware), risk behaviors and use of services were compared between MSM who did and did not receive money or drugs from one or more casual male partners in exchange for oral or anal sex in the past 12 months. Among 8411 MSM, 7.0 % exchanged sex. MSM who exchanged sex were more likely to be non-Hispanic black, live in poverty, have injected drugs, have multiple condomless anal sex partners, be HIV-positive and be HIV-positive-unaware. In multivariable analysis, exchange sex was associated with being HIV-positive-unaware (aPR 1.34, 95 % CI 1.05-1.69) after adjusting for race/ethnicity, age, education, poverty, and injecting drugs. MSM who exchange sex represent an important group to reach with HIV prevention, testing, and care services as they were more likely to report behavioral risk factors that put them at risk of HIV.

Interactive effects among ecosystem services and management practices on crop production: pollination in coffee agroforestry systems.

PubMed

Boreux, Virginie; Kushalappa, Cheppudira G; Vaast, Philippe; Ghazoul, Jaboury

2013-05-21

Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated the impact of pollination services on coffee production, considering variation in fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates coffee flowering across all plantations), soil pH, and nitrogen availability. After accounting for management interventions, bee abundance improved coffee production (number of berries harvested). Some management interventions, such as irrigation, used once to trigger asynchronous flowering, dramatically increased bee abundance at coffee trees. Others, such as the extent and type of tree cover, revealed interacting effects on pollination and, ultimately, crop production. The effects of management interventions, notably irrigation and addition of lime, had, however, far more substantial positive effects on coffee production than tree cover. These results suggest that pollination services matter, but managing the asynchrony of flowering was a more effective tool for securing good pollination than maintaining high shade tree densities as pollinator habitat. Complex interactions across farm and landscape scales, including both management practices and environmental conditions, shape pollination outcomes. Effective production systems therefore require the integrated consideration of management practices in the context of the surrounding habitat structure. This paper points toward a more strategic use of ecosystem services in agricultural systems, where ecosystem services are shaped by the coupling of management interventions and environmental variables.

Factors that influence acceptance of web-based e-learning systems for the in-service education of junior high school teachers in Taiwan.

2012-08-01

Web-based e-learning is not restricted by time or place and can provide teachers with a learning environment that is flexible and convenient, enabling them to efficiently learn, quickly develop their professional expertise, and advance professionally. Many research reports on web-based e-learning have neglected the role of the teacher's perspective in the acceptance of using web-based e-learning systems for in-service education. We distributed questionnaires to 402 junior high school teachers in central Taiwan. This study used the Technology Acceptance Model (TAM) as our theoretical foundation and employed the Structure Equation Model (SEM) to examine factors that influenced intentions to use in-service training conducted through web-based e-learning. The results showed that motivation to use and Internet self-efficacy were significantly positively associated with behavioral intentions regarding the use of web-based e-learning for in-service training through the factors of perceived usefulness and perceived ease of use. The factor of computer anxiety had a significantly negative effect on behavioral intentions toward web-based e-learning in-service training through the factor of perceived ease of use. Perceived usefulness and motivation to use were the primary reasons for the acceptance by junior high school teachers of web-based e-learning systems for in-service training.

Purpose: Increasing demand for autism services is straining service systems. Tailoring services to best meet families’ needs could improve their quality of life and decrease burden on the system. We explored overall, best, and worst met service needs, and predictors of those needs, for families of children with autism spectrum disorders. Methods: Parents of 143 children with autism spectrum disorders (2–18 years) completed a survey including demographic and descriptive information, the Family Needs Survey–Revised, and an open-ended question about service needs. Descriptive statistics characterize the sample and determine the degree to which items were identified and met as needs. Predictors of total and unmet needs were modeled with regression or generalized linear model. Qualitative responses were thematically analyzed. Results: The most frequently identified overall and unmet service needs were information on services, family support, and respite care. The funding and quality of professional support available were viewed positively. Decreased child’s age and income and being an older mother predicted more total needs. Having an older child or mother, lower income, and disruptive behaviors predicted more total unmet needs, yet only disruptive behaviors predicted proportional unmet need. Child’s language or intellectual abilities did not predict needs. Conclusion: Findings can help professionals, funders, and policy-makers tailor services to best meet families’ needs. PMID:25073749

2012-11-01

This work proposes ISKANDARnet Ionospheric Outburst MOnitoring and alert System (IOMOS), along with Ionospheric Outburst Index (IOX) to develop an operational near real-time space weather service for Malaysia. The IOMOS is based on Global Positioning System (GPS) Network-based Real-Time Kinematic (NRTK) concept which is by nature for atmospheric (ionosphere and troposphere) modeling within the network coverage. The elegance of this solution lies in the fact that IOMOS utilize differential ionospheric residual from network of GPS baselines which incur no additional cost for operation. Users will be informed about the ionospheric perturbation through Short Message Service (SMS), email or Twitter®. This approach will ultimately beneficial for the navigation and satellite positioning communities, particularly during the coming Solar Cycle 24. In addition, a combination of local and global GPS network has been employed to study the equatorial ionosphere geomorphology and climatology in the Malaysian sector. Equatorial Total Electron Content (TEC) over Malaysia shows semi-annual, annual, and seasonal variations with maximum values appearing during equinoctial months and minimum during solstices months. The TEC value during vernal equinox is about 21% higher than autumnal equinox, and December solstice exceeds that at the June solstice by around 14%. It is also found that semi-annual variation is present at all levels of solar activity, whereas June solstice predominates December solstice during high solar activity for annual and seasonal variations. In near future, a near real-time TEC derivation system will be developed to support equatorial ionosphere modeling to enhance space weather service for Malaysia.

The incidence of congenital syphilis remains low in the UK, but the morbidity and mortality to babies born to women who are untreated for the condition make testing for the disease antenatally one of the most cost-effective screening programmes. Women attending North Middlesex Hospital, UK with a positive syphilis test at their antenatal booking visit are referred to St Ann's Sexual Health Clinic, London, for management and contact tracing. We were concerned that our initial audit revealed that a large proportion of women referred to our service never attended and recorded partner notification was poor. Following the implementation of recommendations, specifically the introduction of an electronic referral system, re-audit showed an improvement in attendance, contact tracing, documentation and communication.

Considerations for ICRF-3

The Second Realization of the International Celestial Reference Frame (ICRF) used dual-frequency VLBI data acquired for geodetic and astrometric purposes from 1979-2009 by organizations now coordinated by the International VLBI Service for Geodesy and Astrometry (IVS) and analyzed according to the Conventions of the International Earth Rotation and Reference Systems Service (IERS). Since 2009 the data set has been significantly broadened, especially by observations in the Southern Hemisphere, and modeling of astronomical, geophysical and tropospheric effects has progressed. The new southern data appear to cause a systematic zonal declination change in the catalog positions. Over the three decades of the ICRF data set the effect of galactic aberration may be significant. Geophysical and tropospheric models also may affect the source positions. All these effects need to be addressed in preparation for ICRF-3.

On May 11, 2009, Space Shuttle Atlantis roared off of Launch Pad 39A enroute to the Hubble Space Telescope (HST) to undertake its final servicing of HST, Servicing Mission 4. Onboard Atlantis was a small payload called the Relative Navigation Sensor experiment, which included three cameras of varying focal ranges, avionics to record images and estimate, in real time, the relative position and attitude (aka "pose") of the telescope during rendezvous and deploy. The avionics package, known as SpaceCube and developed at the Goddard Space Flight Center, performed image processing using field programmable gate arrays to accelerate this process, and in addition executed two different pose algorithms in parallel, the Goddard Natural Feature Image Recognition and the ULTOR Passive Pose and Position Engine (P3E) algorithms

Desmond, Sharon

2017-03-02

The aim of the present paper was to review the opportunities currently available to health service planners to advance sustainable development in their future-facing roles within health service organisation. Critical challenges and enablers to facilitate health services planners in adopting a pro-environmental lens are discussed. What is known about the topic? Despite its harmful effect on the environment, health has been slower than other industries to embrace the sustainable development agenda. The attitudes and knowledge base of health service planners with regard to environmental sustainability has not been widely studied. For health service planners, embracing pro-environmental considerations in sustainable model of care development is a powerful opportunity to review care paradigms and prepare for the implementation of meaningful, improved health and system efficiency. What does this paper add? This paper advances the case for health service planners to embrace a pro-environmental stance and guides health service leaders in the preparation and implementation of sustainable and improved health and system efficiency. What are the implications for practitioners? Health service planers are in an ideal position to champion the sustainable development agenda as they explore what care is delivered, how care is delivered and where care is delivered. External policy, health service leadership and carbon literacy are advanced as critical contextual factors to facilitate the key role that health service planners can play in building sustainable healthcare organisations.

(1) To examine whether prevalence of burnout is higher among community psychiatric nurses working under recently introduced job specific work systems than among public health nurses (PHNs) engaged in other public health services. (2) To identify work environment factors potentially contributing to burnout. Two groups were examined. The psychiatric group comprised 525 PHNs primarily engaged in public mental health services at public health centres (PHCs) that had adopted the job specific work system. The control group comprised 525 PHNs primarily engaged in other health services. Pines' Burnout Scale was used to measure burnout. Respondents were classified by burnout score into three groups: A (mentally stable, no burnout); B (positive signs, risk of burnout); and C (burnout present, action required). Groups B and C were considered representative of "burnout". A questionnaire was also prepared to investigate systems for supporting PHNs working at PHCs and to define emergency mental health service factors contributing to burnout. Final respondents comprised 785 PHNs. Prevalence of burnout was significantly higher in the psychiatric group (59.2%) than in the control group (51.5%). Responses indicating lack of job control and increased annual frequency of emergency overtime services were significantly correlated with prevalence of burnout in the psychiatric group, but not in the control group. Prevalence of burnout is significantly higher for community psychiatric nurses than for PHNs engaged in other services. Overwork in emergency services and lack of job control appear to represent work environment factors contributing to burnout.

Purpose and context ‘Gesundes Kinzigtal’ is one of the few population-based integrated care approaches in Germany, organising care across all health service sectors and indications. The management company and its contracting partners (the physicians’ network in the region and two statutory health insurers) strive to reach a higher quality of care at a lower overall cost as compared with the German standard. During its first two years of operation (2006–2007), the Kinzigtal project achieved surprisingly positive financial results compared with its reference value. To gain independent evidence on the quality aspects of the system, the management company and its partners provided a remarkable budget for its evaluation by independent scientific institutions. Case description and data sources We will present interim results of a population-based controlled cohort study. In this study, quality of care is checked by relying on health and service quality indicators that have been constructed from health insurers’ administrative data (claims data). Interim results are presented for the intervention region (Kinzigtal area) and the control region (the rest of Baden-Württemberg, i.e., Southwest Germany). Preliminary conclusions and discussion The evaluation of ‘Gesundes Kinzigtal’ is in full progress. Until now, there is no evidence that the surprisingly positive financial results of the Kinzigtal system have been achieved at the expense of care quality. Rather, Gesundes Kinzigtal Integrated Care seems to be about to increasingly realize comparative advantages regarding health service quality (in comparison to the control region).

Eradicating Barriers to Mental Health Care Through Integrated Service Models: Contemporary Perspectives for Psychiatric-Mental Health Nurses.

PubMed

Ellis, Horace; Alexander, Vinette

2016-06-01

There has been renewed, global interest in developing new and transformative models of facilitating access to high-quality, cost-effective, and individually-centered health care for severe mentally-ill (SMI) persons of diverse racial/ethnic, cultural and socioeconomic backgrounds. However, in our present-day health-service delivery systems, scholars have identified layers of barriers to widespread dispersal of well-needed mental health care both nationally and internationally. It is crucial that contemporary models directed at eradicating barriers to mental health services are interdisciplinary in context, design, scope, sequence, and best-practice standards. Contextually, nurses are well-positioned to influence the incorporation and integration of new concepts into operationally interdisciplinary, evidence-based care models with measurable outcomes. The aim of this concept paper is to use the available evidence to contextually explicate how the blended roles of psychiatric mental health (PMH) nursing can be influential in eradicating barriers to care and services for SMI persons through the integrated principles of collaboration, integration and service expansion across health, socioeconomic, and community systems. A large body of literature proposes that any best-practice standards aimed at eliminating barriers to the health care needs of SMI persons require systematic, well-coordinated interdisciplinary partnerships through evidence-based, high-quality, person-centered, and outcome-driven processes. Transforming the conceptual models of collaboration, integration and service expansion could be revolutionary in how care and services are coordinated and dispersed to populations across disadvantaged communities. Building on their longstanding commitment to individual and community care approaches, and their pivotal roles in research, education, leadership, practice, and legislative processes; PMH nurses are well-positioned to be both influential and instrumental in the development of innovative, revolutionary, and transformative paradigmatic models aimed at eradicating treatment barriers, promoting well-being, and reducing preventable mortalities and morbidities among SMI persons.

Ecosystem services are strongly influenced by the landscape configuration of natural and human systems. So they are heterogeneous across landscapes. However lack of the knowledge of spatial variations of ecosystem services constrains the effective management and conservation of ecosystems. We presented a spatially explicit and quantitative assessment of the geographic variations in ecosystem services for the Fuzhou City in 2009 using exploratory spatial data analysis (ESDA) and semivariance analysis. Results confirmed a significant and positive spatial autocorrelation, and revealed several hot-spots and cold-spots for the spatial distribution of ecosystem service intensity (ESI) in the study area. Also the trend surface analysis indicated that the level of ESI tended to be reduced gradually from north to south and from west to east, with a trough in the urban central area, which was quite in accordance with land-use structure. A more precise cluster map was then developed using the range of lag distance, deriving from semivariance analysis, as neighborhood size instead of default value in the software of ESRI ArcGIS 10.0, and geographical clusters where population growth and land-use pressure varied significantly and positively with ESI across the city were also created by geographically weighted regression (GWR). This study has good policy implications applicable to prioritize areas for conservation or construction, and design ecological corridor to improve ecosystem service delivery to benefiting areas.

This study aimed to examine the effectiveness of The Enhanced Support Service (ESS) pilot in reducing custodial violence and disruption, and the associated costs, by observing the behavioural change of the 35 service users who participated in ESS intervention within its first 22 months of operation. Frequencies of recorded incidents of aggressive behaviours, self-harming behaviours, noncompliance, and positive behaviours were counted from routine administrative systems using a coding structure developed in previous studies. The count data were analysed using nonparametric tests and Poisson regression models to derive an Incident Rate Ratio (IRR). Findings suggest the ESS is associated with a reduction in aggressive behaviours and noncompliance, with medium to large effect sizes ( r = .31-.53); however, it was not associated with a reduction in deliberate self-harm or increased positive behaviours. The Poisson models revealed that levels of pre-intervention behaviour, intervention length, intervention completion, and service location had varying effects on postintervention behaviour, with those who completed intervention demonstrating more favourable outcomes. The ESS service model was associated with a reduction in behaviour that challenges, which has implications for the reduction in associated social, economic, and political costs-as well as the commissioning of interventions and future research in this area.

Observer Single-handed Transatlantic Race (OSTAR) participants were aided by a French-American space-based monitoring system which reported the yacht's positions throughout the race, and also served as an emergency locator service. Originating from NASA's Nimbus 6 Satellite, use of this system, called ARGOS made the OSTAR competition the most accurately reported sea race ever conducted. Each boat carried a portable transmitter allowing 88 new sources of oceanographic data available during the race.

Appropriate deployment or posting and transfer (P&T) of health workers - placing the right people in the right positions at the right time - lies at the heart of fostering communities' faith in government health services and cementing the role of the health system as a core social institution. The authors of this paper have been involved in an ongoing transnational dialogue about P&T practices and determinants. This dialogue seeks to call attention to the importance of P&T as a health system function; to urge donors and policy-makers working in health systems, HRH and public administration governance to consider how to address issues around P&T; and to suggest avenues and approaches to research. P&T is a vexed and unresolved issue in many low- and middle-income countries that requires, above all, political commitment to improving public sector services and to new thinking and research. It holds promise as a focal point for inter-disciplinary collaboration in research and implementation that can inform other areas in HRH and health systems strengthening. Innovative social science and management theorizing, and iterative, locally driven interventions that focus on establishing transparent professional norms and building the credibility of government administration, including the health services, are likely the way forward.

Community health workers (CHWs) are uniquely placed to link communities with the health system, playing a role in improving the reach of health systems and bringing health services closer to hard-to-reach and marginalised groups. A systematic review was conducted to determine the extent of equity of CHW programmes and to identify intervention design factors which influence equity of health outcomes. In accordance with our published protocol, we systematically searched eight databases from 2004 to 2014 for quantitative and qualitative studies which assessed access, utilisation, quality or community empowerment following introduction of a CHW programme according to equity stratifiers (place of residence, gender, socio-economic position and disability). Thirty four papers met inclusion criteria. A thematic framework was applied and data extracted and managed, prior to charting and thematic analysis. To our knowledge this is the first systematic review that describes the extent of equity within CHW programmes and identifies CHW intervention design features which influence equity. CHW programmes were found to promote equity of access and utilisation for community health by reducing inequities relating to place of residence, gender, education and socio-economic position. CHWs can also contribute towards more equitable uptake of referrals at health facility level. There was no clear evidence for equitable quality of services provided by CHWs and limited information regarding the role of the CHW in generating community empowerment to respond to social determinants of health. Factors promoting greater equity of CHW services include recruitment of most poor community members as CHWs, close proximity of services to households, pre-existing social relationship with CHW, provision of home-based services, free service delivery, targeting of poor households, strengthened referral to facility, sensitisation and mobilisation of community. However, if CHW programmes are not well planned some of the barriers faced by clients at health facility level can replicate at community level. CHWs promote equitable access to health promotion, disease prevention and use of curative services at household level. However, care must be taken by policymakers and implementers to take into account factors which can influence the equity of services during planning and implementation of CHW programmes.
