  4. Options for pricing ancillary services in a deregulated power system

    Yamin, Hatim Yahya

    2001-07-01

    GENCOs in restructured systems are compensated for selling energy in the market. In a restructured market, a mechanism is required to entice participants in the market to provide ancillary services and to ensure adequate compensation that would guarantee its economic viability. The ISO controls the dispatch of generation, manages the reliability of the transmission grid, provides open access to the transmission, buys and provides ancillary services as required, coordinates day-ahead, hour-ahead schedules and performs real time balancing of load and generation, settles real time imbalances and ancillary services sales and purchases. The ISO, also, administers congestion management protocols for the transmission grid. Since the ISO does not own any generating units it must ensure that there is enough reserves for maintaining reliability according to FERC regulations, and sufficient unloaded generating capacity for balancing services in a real-time market. The ISO could meet these requirements by creating a competitive market for ancillary services, which are metered and remain unbundled to provide an accurate compensation for each supplier and cost to each consumer, In this study, we give an overview for restructuring and ancillary services in a restructured power marketplace. Also, we discuss the effect of GENCOs' actions in the competitive energy and ancillary service markets. In addition, we propose an auction market design for hedging ancillary service costs in California market. Furthermore, we show how to include the n-1 and voltage contingencies in security constrained unit commitment. Finally, we present two approaches for GENCOs' unit commitment in a restructured power market; one is based on game theory and the other is based on market price forecasting. In each of the two GENCOs' unit commitment approaches, we discuss the GENCOs' optimal bidding strategies in energy and ancillary service markets to maximize the GENCOs' profit.

    Bert, Jack M

    2008-01-01

    The delivery of high quality medical services is approaching a crisis situation in the United States. As physician reimbursements decline and overhead increases, orthopedic surgeons must seek additional sources of revenue to remain financially viable and control the quality of medical care that they deliver. The orthopedic surgeon group is well positioned to control its own service lines and deliver excellent patient care as a result. This article reviews the possibilities of multiple types of ancillary service lines available for the orthopedic group practice. PMID:18061762

    In addition to providing energy to end-consumers, power system operators are also responsible for ensuring system reliability. To this end, power markets maintain an array of ancillary services to ensure it is always possible to balance the supply and demand for energy in real-time. A subset of these ancillary services are commonly procured through market-based mechanisms: namely, Regulation, Spinning, and Non-spinning Reserves.

  11. Using OWL-S to annotate services with ancillary behaviour

    2004-01-01

    This paper introduces the concept of services with ancillary behaviour and illustrates the use of OWL-S to semantically describe them. The OWL-S syntax used reflects the dynamic and core-function independent nature of ancillary behaviour. The approach is illustrated on the case of a ubiquitous computing system designed to offer care in the home of a cardiac patient. Here one of the challenges is to ensure service availability, team awareness and transaction atomicity. The concept of commitmen...

  12. Integration of Flexible Consumers in the Ancillary Service Markets

    2014-01-01

    Flexible consumption devices are often able to quickly adjust the power consumption making these devices very well suited as providers of fast ancillary services such as primary and secondary reserves. As these reserves are among the most well-paid ancillary services, it is an interesting idea...... to let an aggregator control a portfolio of flexible consumption devices and sell the accumulated flexibility in the primary and secondary reserve markets. However, two issues make it difficult for a portfolio of consumption devices to provide ancillary services: First, flexible consumption devices only...... have a limited energy capacity and are therefore not able to provide actual energy deliveries. Second, it is often difficult to make an accurate consumption baseline estimate for a portfolio of flexible consumption devices. These two issues do not fit the current regulations for providing ancillary...

  13. The evolving design of RTO ancillary service markets

    Although the markets for ancillary services at the North American Independent System Operators are often structured in quite different ways there is an emerging set of core design elements that represent a rough consensus as to what the optimal design configuration for ancillary services should be, albeit with some regional variation. This paper looks back at how the design of ancillary services markets has recently evolved to put this development in context. Thereafter it examines the methods by which ancillary services are procured by highlighting the procurement practices at a number of different Independent System Operators, principally those in California, New York, New England, Texas and the PJM Interconnection, in an attempt to tease out the remaining reasons why the ancillary service markets are still so different. This is important as there are many innovations that are not rooted in regional differences but reflect genuine technical advances and economic efficiency gains and can be replicated across other ISOs to produce more efficient designs, greater reliability and lower costs.

  14. Loads Providing Ancillary Services: Review of International Experience

    Heffner, Grayson; Goldman, Charles; Kintner-Meyer, Michael

    2007-05-01

    In this study, we examine the arrangements for and experiences of end-use loads providing ancillary services (AS) in five electricity markets: Australia, the United Kingdom (UK), the Nordic market, and the ERCOT and PJM markets in the United States. Our objective in undertaking this review of international experience was to identify specific approaches or market designs that have enabled customer loads to effectively deliver various ancillary services (AS) products. We hope that this report will contribute to the ongoing discussion in the U.S. and elsewhere regarding what institutional and technical developments are needed to ensure that customer loads can meaningfully participate in all wholesale electricity markets.

  15. Optimal generator bidding strategies for power and ancillary services

    Morinec, Allen G.

    As the electric power industry transitions to a deregulated market, power transactions are made upon price rather than cost. Generator companies are interested in maximizing their profits rather than overall system efficiency. A method to equitably compensate generation providers for real power, and ancillary services such as reactive power and spinning reserve, will ensure a competitive market with an adequate number of suppliers. Optimizing the generation product mix during bidding is necessary to maximize a generator company's profits. The objective of this research work is to determine and formulate appropriate optimal bidding strategies for a generation company in both the energy and ancillary services markets. These strategies should incorporate the capability curves of their generators as constraints to define the optimal product mix and price offered in the day-ahead and real time spot markets. In order to achieve such a goal, a two-player model was composed to simulate market auctions for power generation. A dynamic game methodology was developed to identify Nash Equilibria and Mixed-Strategy Nash Equilibria solutions as optimal generation bidding strategies for two-player non-cooperative variable-sum matrix games with incomplete information. These games integrated the generation product mix of real power, reactive power, and spinning reserve with the generators's capability curves as constraints. The research includes simulations of market auctions, where strategies were tested for generators with different unit constraints, costs, types of competitors, strategies, and demand levels. Studies on the capability of large hydrogen cooled synchronous generators were utilized to derive useful equations that define the exact shape of the capability curve from the intersections of the arcs defined by the centers and radial vectors of the rotor, stator, and steady-state stability limits. The available reactive reserve and spinning reserve were calculated given a

  16. Demand Response Resources for Energy and Ancillary Services (Presentation)

    Hummon, M.

    2014-04-01

    Demand response (DR) resources present a potentially important source of grid flexibility particularly on future systems with high penetrations of variable wind an solar power generation. However, DR in grid models is limited by data availability and modeling complexity. This presentation focuses on the co-optimization of DR resources to provide energy and ancillary services in a production cost model of the Colorado test system. We assume each DR resource can provide energy services by either shedding load or shifting its use between different times, as well as operating

  17. Ancillary services and optimal household energy management with photovoltaic production

    This article presents a project designed to increase the monetary value of photovoltaic (PV) solar production for residential applications. To contribute to developing new functionalities for this type of PV system and an efficient control system for optimising its operation, this article explains how the proposed system could contract to provide ancillary services, particularly the supply of active power services. This provision of service by a PV-based system for domestic applications, not currently available, has prompted a market design proposal related to the distribution system. The mathematical model for calculating the system's optimal operation (sources, load and exchanges of power with the grid) results in a linear mix integer optimisation problem in which the objective is to maximise the profits achieved by taking part in the electricity market. Our approach is illustrated in a case study. PV producers could gain by taking part in the markets for balancing power or ancillary services despite the negative impact on profit of several types of uncertainty, notably the intermittent nature of the PV source.

  20. Usage of direct search methods in predictive control of ancillary services

    Most European transmission systems are interconnected to ensure the reliability and accessibility of electric power supply. Transmission system operators (TSOs) are responsible for ensuring that contracted cross-border supplies are available and that deficits are accommodated. TSOs typically buy ancillary services in advance for use in periods of deficit. This paper described a predictive control approach for ancillary services in interconnected electricity systems. The model was designed to predict the difference between contracted and actual cross-border transmission of electric power. The power sources were considered as individual power plants. The receding horizon principle was applied in order to compute the time sequences of individual sources for longer prediction periods using only the initial part of the sequences. Coverage included positive tertiary regulation; negative tertiary regulation; quickstart; dispatch reserve; and energy bought from other countries. Inputs were converted into binary values for the optimization algorithm. The technical properties of individual sources were used as fundamental constraints. The optimization algorithm was able to determine optimal sequences of ancillary services within a prediction horizon of 6 hours. 6 refs., 1 tab., 6 figs.

  1. Commercial Building Loads Providing Ancillary Services in PJM

    MacDonald, Jason; Kiliccote, Sila; Boch, Jim; Chen, Jonathan; Nawy, Robert

    2014-06-27

    The adoption of low carbon energy technologies such as variable renewable energy and electric vehicles, coupled with the efficacy of energy efficiency to reduce traditional base load has increased the uncertainty inherent in the net load shape. Handling this variability with slower, traditional resources leads to inefficient system dispatch, and in some cases may compromise reliability. Grid operators are looking to future energy technologies, such as automated demand response (DR), to provide capacity-based reliability services as the need for these services increase. While DR resources are expected to have the flexibility characteristics operators are looking for, demonstrations are necessary to build confidence in their capabilities. Additionally, building owners are uncertain of the monetary value and operational burden of providing these services. To address this, the present study demonstrates the ability of demand response resources providing two ancillary services in the PJM territory, synchronous reserve and regulation, using an OpenADR 2.0b signaling architecture. The loads under control include HVAC and lighting at a big box retail store and variable frequency fan loads. The study examines performance characteristics of the resource: the speed of response, communications latencies in the architecture, and accuracy of response. It also examines the frequency and duration of events and the value in the marketplace which can be used to examine if the opportunity is sufficient to entice building owners to participate.

  2. Effective Ancillary Services Market Designs on High Wind Power Penetration Systems: Preprint

    Ela, E.; Kirby, B.; Navid, N.; Smith, J. C.

    2011-12-01

    This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power. Ancillary services markets have been developed in many of the restructured power system regions throughout the world. Ancillary services include the services that support the provision of energy to support power system reliability. The ancillary services markets are tied tightly to the design of the energy market and to the physics of the system and therefore careful consideration of power system economics and engineering must be considered in their design. This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power.

  3. An assessment of market and policy barriers for demand response providing ancillary services in U.S. electricity markets

    An impact of increased variable renewable generation is the need for balancing authorities to procure more ancillary services. While demand response resources are technically capable of providing these services, current experience across the U.S. illustrates they are relatively minor players in most regions. Accessing demand response resources for ancillary services may require a number of changes to policies and common practices at multiple levels. Regional reliability councils must first define ancillary services such that demand response resources may provide them. Once the opportunity exists, balancing authorities define and promulgate rules that set the infrastructure investments and performance attributes of a resource wishing to provide such services. These rules also dictate expected revenue streams which reveal the cost effectiveness of these resources. The regulatory compact between utility and state regulators, along with other statutes and decisions by state policymakers, may impact the interest of demand response program providers to pursue these resources as ancillary service providers. This paper identifies within these broad categories specific market and policy barriers to demand response providing ancillary services in different wholesale and retail environments, with emphasis on smaller customers who must be aggregated through a program provider to meet minimum size requirements for wholesale transactions. - Highlights: • We identify barriers keeping demand response from providing ancillary services. • Institutional, financial and program provider business model barriers exist. • Product definitions and rules do not always accommodate demand response well. • Expected revenues are uncertain and may not exceed required investments costs. • Regulatory compact and state statutes limit opportunities for program providers

  4. Transactive Control and Coordination of Distributed Assets for Ancillary Services

    The need to diversify energy supplies, the need to mitigate energy-related environmental impact, and the entry of electric vehicles in large numbers present challenges and opportunities to power system professionals. Wind and solar power provide many benefits, and to reap the benefits the resulting increased variability—forecasted as well as unforecasted—should be addressed. Demand resources are receiving increasing attention as one means of providing the grid balancing services. Control and coordination of a large number (~millions) of distributed smart grid assets requires innovative approaches. One such is transactive control and coordination (TC2)—a distributed, agent-based incentive and control system. The TC2 paradigm is to create a market system with the following characteristics: • Participation should be entirely voluntary. • The participant decides at what price s/he is willing to participate. • The bids and responses are automated. Such an approach has been developed and demonstrated by Pacific Northwest National Laboratory for energy markets. It is the purpose of this project to develop a similar approach for ancillary services. In this report, the following ancillary services are considered: • spinning reserve • ramping • regulation. These services are to be provided by the following devices: • refrigerators • water heaters • clothes dryers • variable speed drives. The important results are summarized below: The regulation signal can be divided into an energy-neutral high frequency component and a low frequency component. The high frequency component is particularly well suited for demand resources. The low frequency component, which carries energy non-neutrality, can be handled by a combination of generators and demand resources. An explicit method for such a separation is obtained from an exponentially weighted moving average filter. Causal filters (i.e., filters that process only present and past values of a signal

  6. Technical and economic aspects of ancillary services markets in the electric power industry: an international comparison

    We present a comparative analysis of technical and economic aspects of ancillary services on the markets of England and Wales, Nordic Countries, California, Argentina, Australia and Spain, comparing the services of voltage control, frequency regulation and system restoration. All the analyzed markets rely on the existence of an administrator of ancillary services, function that leads to the figure of the system operator. Among the services analyzed, the mandatory nature of voltage control and primary frequency regulation stands out, being both the ancillary services with the higher market price and the shortest period of time requirements. In general, the recognized costs of the services correspond to investments operation, maintenance, and opportunity costs. In the provision of these ancillary services, there are no clear preferences for a particular resource allocation mechanism, where mandatory provision, auctions, competitive offers and different time length bilateral contracts are combined

  13. Security-constrained ancillary services allocation and pricing in integrated markets

    Ancillary services are used to control system frequency and to ensure the secure and reliable transmission of electricity from suppliers to consumers. A new dispatch formulation for determining optimal network security constraints for generator active-power schedules and the allocation of ancillary services was presented in this study. The conventional optimal power flow (OPF) formulation was based on an integrated market model with energy and ancillary services procured simultaneously using a co-optimization process. The Newton method for optimizing the Lagrange function formed from individual cost functions and constraints was used. The contingency formulation considered power demand variations at load nodes. Additional control variables were added in order to meet new load demands in the dispatch formulation. A Lagrange function was used to develop an extended set of security constraints as well as individual prices for ancillary service providers. Costs related to maintenance, lower efficiency and lower active-power generation were the variable costs of frequency control. Services compensating the transmission system losses between consumers and suppliers were described as grid loss compensation services. Case studies of representative power systems were used to verify the new dispatch calculation method. The study showed that minimizing the procurement costs of ancillary services can lead to insecure system operations. 13 refs., 3 tabs., 3 figs.

Most of the tariffs filed with FERC price these services on the basis of traditional cost-of-service (embedded) costs, Because most of these services are provided by generating units, however, it should be possible to create competitive markets for them. This paper describes, the structure of, and results from, a spreadsheet model that simulates markets for seven services: losses,...

    Johnstone, Peter A S; Hendrickson, Julie A W; Dernbach, Allison J; Secord, Ann R; Parker, John C; Favata, Michael A; Puckett, Michael L

    2003-01-01

    Within the naval medical center construct, the disparate disciplines encompassed within ancillary services lend themselves to formal quality analysis and process improvement. This analysis uses the Six Sigma approach. Error rates were investigated and calculated for various processes within ancillary services at Naval Medical Center, San Diego. These were translated into the common metric of defects per million opportunities (DPMO). DPMO rates vary between 21.5 and 420,000. These correspond to Sigma values from 1.7 to approaching 6. Rates vary with biological complexity of the system and the degree of automation available. Some ancillary services translate well into a Six Sigma schema. Systems with high potential patient risk if performed poorly and those amenable to second checking and computer oversight may be candidates for such optimization. This should be undertaken in a local environment conducive to individual error reporting, and in a corporate environment with the will and funding to support the transition. PMID:12593375

  17. Mixed integer non-linear programming and Artificial Neural Network based approach to ancillary services dispatch in competitive electricity markets

    Highlights: • Ancillary services market management. • Ancillary services requirements forecast based on Artificial Neural Network. • Ancillary services clearing mechanisms without complex bids and with complex bids. - Abstract: Ancillary services represent a good business opportunity that must be considered by market players. This paper presents a new methodology for ancillary services market dispatch. The method considers the bids submitted to the market and includes a market clearing mechanism based on deterministic optimization. An Artificial Neural Network is used for day-ahead prediction of Regulation Down, regulation-up, Spin Reserve and Non-Spin Reserve requirements. Two test cases based on California Independent System Operator data concerning dispatch of Regulation Down, Regulation Up, Spin Reserve and Non-Spin Reserve services are included in this paper to illustrate the application of the proposed method: (1) dispatch considering simple bids; (2) dispatch considering complex bids

This paper summarizes AS in China and analyzes the necessary characteristics and advantages of industrial users to provide AS according to their response mechanism. Cement manufacturing and aluminum smelter processes are selected as two representatives of responsive industrial loads. An agent-based model that includes generation, industrial user, and grid agents is proposed. Using two case studies, we analyze the integrated power management of conventional units and industrial loads in day-ahead and real-time AS scheduling based on real device parameters, price mechanisms and production data. The simulation results indicate that the participation of responsive industrial loads in the provision of AS, in China, can improve the coal consumption rate and the system-wide load factor as well as reduce the total system cost for the provision of AS significantly.

    The ECCAD database (Emissions of atmospheric Compounds and Compilation of Ancillary Data) provides a user-friendly access to global and regional surface emissions for a large set of chemical compounds and ancillary data (land use, active fires, burned areas, population,etc). The emissions inventories are time series gridded data at spatial resolution from 1x1 to 0.1x0.1 degrees. ECCAD is the emissions database of the GEIA (Global Emissions InitiAtive) project and a sub-project of the French Atmospheric Data Center AERIS (http://www.aeris-data.fr). ECCAD has currently more than 2200 users originating from more than 80 countries. The project benefits from this large international community of users to expand the number of emission datasets made available. ECCAD provides detailed metadata for each of the datasets and various tools for data visualization, for computing global and regional totals and for interactive spatial and temporal analysis. The data can be downloaded as interoperable NetCDF CF-compliant files, i.e. the data are compatible with many other client interfaces. The presentation will provide information on the datasets available within ECCAD, as well as examples of the analysis work that can be done online through the website: http://eccad.aeris-data.fr.

    With significantly increasing share of variable renewable power generation like wind and solar PV, the need in the power system for ancillary services supporting the network frequency, voltage, etc. changes. Turning this issue around, market opportunities will emerge for wind and solar PV technology to deliver such grid services. In the European power system, adequate market mechanisms need to be developed to ensure that there will be an efficient trading of these services. For that purpose a range of (economic) characteristics of wind (and solar) power as providers of grid services need to be better understood. This relates both to the technical capabilities of the plants for delivering specific services and to the quantification of the needs. The paper presents the approach of the European lEE project REserviceS, aiming at establishing reference guidance for the ongoing developments in Europe of network codes and electricity market design. Economic insights gained from REserviceS will be shaped into recommendations to be used when establishing electricity market mechanisms and Network Codes at EU level. The project approach presented in the paper consists of two main parts namely (1) conceptually analyzing system needs for ancillary services and at assessing the technical aspects of and cost of delivering these services by solar PV and wind power, in scenarios of high renewable penetration. (2) Investigation of the need for ancillary services in typical transmission and distribution networks, and the cost and options to deliver these services at high penetration. The paper will give an overview of case studies envisaged, together with the intended methods used for the analysis. The paper also gives some initial project results. It presents the outcome of the assessment of ancillary services that are especially relevant for wind and solar power. These are mainly related to frequency, voltage control and restoration of the system. In addition, based on existing

  5. VOLTTRON-Based System for Providing Ancillary Services with Residential Building Loads

    Jin, Xin

    2016-07-01

    Ancillary services entail controlled modulation of building equipment to maintain a stable balance of generation and load in the power system. Ancillary services include frequency regulation and contingency reserves, whose acting time ranges from several seconds to several minutes. Many pilot studies have been implemented to use industrial loads to provide ancillary services, and some have explored services from commercial building loads or electric vehicle charging loads. Residential loads, such as space conditioning and water heating, represent a largely untapped resource for providing ancillary services. The residential building sector accounts for a significant fraction of the total electricity use in the United States. Many loads in residential buildings are flexible and could potentially be curtailed or shifted at the request of the grid. However, there are many barriers that prevent residential loads being widely used for ancillary services. One of the major technical barriers is the lack of communication capabilities between end-use devices and the grid. End-use devices need to be able to receive the automatic generation control (AGC) signal from the grid operator and supply certain types of telemetry to verify response. With the advance of consumer electronics, communication-enabled, or 'connected,' residential equipment has emerged to overcome the communication barrier. However, these end-use devices have introduced a new interoperability challenge due to the existence of numerous standards and communication protocols among different end devices. In this paper, we present a VOLTTRON-based system that overcomes these technical challenges and provides ancillary services with residential loads. VOLTTRON is an open-source control and sensing platform for building energy management, facilitating interoperability solutions for end devices. We have developed drivers to communicate and control different types of end devices through standard

  6. Alternative Approaches for Incentivizing the Frequency Responsive Reserve Ancillary Service

    Ela, E.; Milligan, M.; Kirby, B.; Tuohy, A.; Brooks, D.

    2012-03-01

    Frequency responsive reserve is the autonomous response of generators and demand response to deviations of system frequency, usually as a result of the instantaneous outage of a large supplier. Frequency responsive reserve arrests the frequency decline resulting in the stabilization of system frequency, and avoids the triggering of under-frequency load-shedding or the reaching of unstable frequencies that could ultimately lead to system blackouts. It is a crucial service required to maintain a reliable and secure power system. Regions with restructured electricity markets have historically had a lack of incentives for frequency responsive reserve because generators inherently provided the response and on large interconnected systems, more than sufficient response has been available. This may not be the case in future systems due to new technologies and declining response. This paper discusses the issues that can occur without proper incentives and even disincentives, and proposes alternatives to introduce incentives for resources to provide frequency responsive reserve to ensure an efficient and reliable power system.

    This study provides an examination of various market and policy barriers to demand response providing ancillary services in both ISO/RTO and non-ISO/RTO regions, especially at the program provider level. It is useful to classify barriers in order to create a holistic understanding and identify parties that could be responsible for their removal. This study develops a typology of barriers focusing on smaller customers that must rely on a program provider (i.e., electric investor owned utility or IOU, ARC) to create an aggregated DR resource in order to bring ancillary services to the balancing authority. The barriers were identified through examinations of regulatory structures, market environments, and product offerings; and discussions with industry stakeholders and regulators. In order to help illustrate the differences in barriers among various wholesale market designs and their constituent retail environments, four regions were chosen to use as case studies: Colorado, Texas, Wisconsin, and New Jersey.

  10. Identifying children in need of ancillary and enabling services: a population approach.

    Benedict, Ruth E; Farel, Anita M

    2003-12-01

    Children with chronic or disabling conditions use health, education and social services at a higher rate than their healthy peers. Estimates of the number of children in need of these specialized services are widely varied and often depend on categorical definitions that do not account for either the diversity or commonality of their experiences. Developing methods for identifying the population in need of services, particularly children likely to use long-term ancillary (audiology, occupational, physical or speech therapy, or social work) and/or enabling services (special equipment, personal care assistance, respite care, transportation, or environmental modifications), is essential for effective policy and program implementation. This study examines several recent attempts to operationalize definitions of children with chronic conditions using a noncategorical classification approach. Particular emphasis is placed on the subgroup of children identified as having functional limitations. Proposed operational definitions of children with functional limitations are compared using data from the 1994-1995 Disability Supplement to the US National Health Interview Survey. Estimates of the number of children reported to be using ancillary and enabling services are generated and compared across operational definitions of functional limitation as well as by the number, severity, and type (i.e. mobility, self-care, communication/sensory, social cognition/learning ability) of limitation. Depending on the operational definition selected, 9-14% of US community-dwelling children are estimated to have functional limitations. Among children with limitations, 26-30% regularly use ancillary services and 11-14% use enabling services. The strengths, limitations, and potential applications for each operational definition are discussed. PMID:14512235

  13. Resource and revenue potential of California residential load participation in ancillary services

    Increasing penetrations of intermittent renewable energy resources will require additional power system services. California recently adopted an energy storage mandate to support its renewable portfolio standard, which requires 33% of delivered energy from renewables by 2020. The objective of this paper is to estimate the amount of energy storage that could be provided by residential thermostatically controlled loads, such as refrigerators and air conditioners, and the amount of revenue that could be earned by loads participating in ancillary services markets. We model load aggregations as virtual energy storage, and use simple dynamical system models and publicly available data to generate our resource and revenue estimates. We find that the resource potential is large: 10–40 GW/8–12 GWh, which is significantly more than that required by the mandate. We also find that regulation and spinning/non-spinning reserve revenues vary significantly depending upon type of load and, for heat pumps and air conditioners, climate zone. For example, mean regulation revenues for refrigerators are $11/year, for electric water heaters are $24/year, for air conditioners are $0-32/year, and for heat pumps are $22–56/year. Both consumer choices, such as appliance settings, and policy, such as the design of ancillary service compensation and appliance standards, could increase revenue potentials. - Highlights: • California's energy storage mandate requires 1.325 GW of energy storage by 2020. • Residential loads such as refrigerators have thermal energy storage. • California's residential loads could provide 10-40 GW/8-12 GWh of storage. • Loads participating in ancillary services markets could earn up to $56/load/year. • Consumer choices and policy mechanisms could increase revenue potentials

  16. An integrated pan-European ancillary services market for frequency control

    Real-time balancing of mismatches between consumption and production is one of the key elements for the secure operation of power systems. This takes place within the framework of ancillary services managed by respective national transmission system operating companies. The objective of this paper is to investigate the option of one integrated pan-European ancillary services market. Our contribution is twofold: quantifying the potential benefit of such an option and outlining a possible approach to such an option highlighting its positive properties as well as risks and challenges. In several recently published considerations of pan-European electricity supply models this topic has not been adequately addressed, but we believe it is one of the crucial subjects in shaping the future electricity supply in Europe. -- Author-Highlights: •We investigated the option of a one-area market for frequency control in Continental Europe. •For the current situation a centralised approach may lead to a significant reduction of control reserves. •In the long run it is a possibility to avoid a tremendous increase of needed control reserves. •The implementation of an integrated market is not to be underestimated

    The Pacific Gas and Electric Company (PG&E) is conducting a pilot program to investigate the technical feasibility of bidding certain demand response (DR) resources into the California Independent System Operator's (CAISO) day-ahead market for ancillary services nonspinning reserve. Three facilities, a retail store, a local government office building, and a bakery, are recruited into the pilot program. For each facility, hourly demand, and load curtailment potential are forecasted two days ahead and submitted to the CAISO the day before the operation as an available resource. These DR resources are optimized against all other generation resources in the CAISO ancillary service. Each facility is equipped with four-second real time telemetry equipment to ensure resource accountability and visibility to CAISO operators. When CAISO requests DR resources, PG&E's OpenADR (Open Automated DR) communications infrastructure is utilized to deliver DR signals to the facilities energy management and control systems (EMCS). The pre-programmed DR strategies are triggered without a human in the loop. This paper describes the automated system architecture and the flow of information to trigger and monitor the performance of the DR events. We outline the DR strategies at each of the participating facilities. At one site a real time electric measurement feedback loop is implemented to assure the delivery of CAISO dispatched demand reductions. Finally, we present results from each of the facilities and discuss findings.

  18. Development of modified rational buyer auction for procurement of ancillary services utilizing participation matrix

    The rational buyer auction is based on a simultaneous auction that is the redesigned auction mechanism for ancillary services by the California independent system operator (CAISO). The incentive for the rational buyer auction is CAISO's intent to adopt a common sense rule of substituting higher-quality lower-cost services for lower-quality higher-cost services, when it results in reduced total procurement cost. For the purposes of designing a desirable auction where the minimum cost for the objective function as well as prevention of price reversal are achieved, either the payment cost in marginal pricing auction must be lowered or price reversal in rational buyer auction must be avoided. The objectives of this study are (a) to develop a newly proposed 'modified rational buyer' auction that does not allow price reversal and (b) to propose and validate a solution procedure that is based on participation matrix and discrete programming. The validation of the proposed solution procedure is accomplished through examination of two case studies available in the literature. Based on the first case study data, it is shown that the newly developed modified rational buyer auction avoids price reversal occurrence, while the total payment of ISO is increased by 5.8%, as compared with rational buyer auction. Also in comparison with marginal pricing auction, the ISO payment is lowered by 38.8%, when the newly developed modified rational buyer auction is utilized. For future work, it is recommended that the application of the modified rational buyer auction to joint dispatch of energy and ancillary services is investigated. (author)

  19. Electric industry restructuring, ancillary services, and the potential impact on wind

    1997-12-31

    The new competitive electric power environment raises increased challenges for wind power. The DOE and EPRI wind programs have dealt extensively with the traditional vertically integrated utility planning and operating environment in which the host utility owns the generation (or purchases the power) and provides dispatch and transmission services. Under this traditional environment, 1794 MW of wind power, principally in California, have been successfully integrated into the U.S. electric power system. Another 4200 MW are installed elsewhere in the world. As issues have arisen, such as intermittency and voltage regulation, they have been successfully addressed with accepted power system procedures and practices. For an intermittent, non-dispatchable resource such as wind, new regulatory rules affecting power transmission services, raise questions about which ancillary services wind plants will be able to sell, which they will be required to purchase, and what the economic impacts will be on individual wind projects. This paper begins to look at issues of concern to wind in a restructured electric industry. The paper first briefly looks at the range of unbundled services and comments on their unique significance to wind. To illustrate the concerns that arise with restructuring, the paper then takes a more detailed look at a single service: regulation. Finally, the paper takes a brief look at technologies and strategies that could improve the competitive position of wind.

  2. Cost-Causation-Based Tariffs for Wind Ancillary Service Impacts: Preprint

    Kirby, B.; Milligan, M.; Wan, Y.

    2006-06-01

    Conference paper discussing the integration cost of wind. Although specific tariffs for wind generation for ancillary services are uncommon, we anticipate that balancing authorities (control areas) and other entities will move toward such tariffs. Tariffs for regulation and imbalance services should be cost-based, recognize the relevant time scales that correspond with utility operational cycles, and properly allocate those costs to those entities that cause the balancing authority to incur the costs. In this paper, we present methods for separating wind's impact into regulation and load following (imbalance) time scales. We show that approximating these impacts with simpler methods can significantly distort cost causation and even cause confusion between the relevant time scales. We present results from NREL's wind data collection program to illustrate the dangers of linearly scaling wind resource data from small wind plants to approximate the wind resource data from large wind plants. Finally, we provide a framework for developing regulation and imbalance tariffs, we outline methods to begin examining contingency reserve requirements for wind plants, we provide guidance on the important characteristics to consider, and we provide hypothetical cases that the tariff can be tested against to determine whether the results are desired.

  3. Accessibility of adolescent health services

    S Richter

    2000-09-01

    Full Text Available Adolescents represent a large proportion of the population. As they mature and become sexually active, they face more serious health risks. Most face these risks with too little factual information, too little guidance about sexual responsibility and multiple barriers to accessing health care. A typical descriptive and explanatory design was used to determine what the characteristics of an accessible adolescent health service should be. Important results and conclusions that were reached indicate that the adolescent want a medical doctor and a registered nurse to be part of the health team treating them and they want to be served in the language of their choice. Family planning, treatment of sexually transmitted diseases and psychiatric services for the prevention of suicide are services that should be included in an adolescent accessible health service. The provision of health education concerning sexual transmitted diseases and AIDS is a necessity. The service should be available thought out the week (included Saturdays and within easy reach. It is recommended that minor changes in existing services be made, that will contribute towards making a health delivery service an adolescent accessible service. An adolescent accessible health service can in turn make a real contribution to the community’s efforts to improve the health of its adolescents and can prove to be a rewarding professional experience to the health worker.

  5. Impact of Production from Photovoltaic Power Plants on Increase of Ancillary Services in the Czech Republic

    Martin Smocek

    2016-01-01

    Full Text Available Renewable energy resources represent a noticeable part of the overall energetic concept development. New integration of renewable energy resources into power grids has a significant impact on the reliability and quality of power supply. The major problem of the photovoltaic and wind power plants is their dependency on weather conditions, since it has a direct effect on their immediate output produced that shows stochastic behaviour. These stochastic outputs result in very adverse impacts on the power grid. Further development of these resources could lead to exceeding of the control and absorption abilities of the power grid. The power grid must be set in balance with respect to the production and consumption of electric power at any time. The operation of photovoltaic power plants impair keeping this balance. That has an adverse impact on the very operation and maintenance of network parameters within the extent required. This survey deals with analysis focused on operation of the photovoltaic power plants with respect to the increase of reserve power in ancillary services in the Czech Republic.

  6. Analysis of the Effects of a Flexible Ramping Ancillary Service Product on Power System Operations: Preprint

    Krad, Ibrahim; Ibanez, Eduardo; Ela, Erik

    2015-10-19

    The recent increased interest in utilizing variable generation (VG) resources such as wind and solar in power systems has motivated investigations into new operating procedures. Although these resources provide desirable value to a system (e.g., no fuel costs or emissions), interconnecting them provides unique challenges. Their variable, non-controllable nature in particular requires significant attention, because it directly results in increased power system variability and uncertainty. One way to handle this is via new operating reserve schemes. Operating reserves provide upward and downward generation and ramping capacity to counteract uncertainty and variability prior to their realization. For instance, uncertainty and variability in real-time dispatch can be accounted for in the hour-ahead unit commitment. New operating reserve methodologies that specifically account for the increased variability and uncertainty caused by VG are currently being investigated and developed by academia and industry. This paper examines one method inspired by the new operating reserve product being proposed by the California Independent System Operator. The method is based on examining the potential ramping requirements at any given time and enforcing those requirements via a reserve demand curve in the market-clearing optimization as an additional ancillary service product.

    The German government aims at a share of electricity generation based on renewable sources (RES-E) of more than 30% by 2020. A major part of this share will be reached by the use of wind power plants (WPP). Therefore, when amending the Renewable Energy Sources Act (EEG) in June 2008, the German government acknowledged the importance of enhanced technical requirements for WPP and announced the development of a respective technical ordinance. For all WPP that go into operation after June 2010, full grid code-compliance becomes a precondition for privileged network access, receipt of feed-in tariff, and extra payments (''ancillary services bonus''). The basis for the technical requirements in the EEG has been laid down by Medium-Voltage (MV)-Directive 2008 and the TransmissionCode 2007. However, the work of the authors - consulting the German government during the development of the technical ordinance - showed that the TransmissionCode 2007 needed careful review and some clarifying specifications were proposed. Eventually, the so called ''Ancillary Services Ordinance'' for wind power plants went into power in July 2009. The interrelation between all three grid codes as well as their specifications and implications for renewable energy sources generators, with special regard to wind power plants, are presented in this paper.

    Revenue insufficiency, or the missing money problem, occurs when the revenues that generators earn from the market are not sufficient to cover both fixed and variable costs to remain in the market and/or justify investments in new capacity, which may be needed for reliability. The near-zero marginal cost of variable renewable generators further exacerbates these revenue challenges. Estimating the extent of the missing money problem in current electricity markets is an important, nontrivial task that requires representing both how the power system operates and how market participants behave. This paper explores the missing money problem using a production cost model that represented a simplified version of the Electric Reliability Council of Texas (ERCOT) energy-only market for the years 2012-2014. We evaluate how various market structures -- including market behavior, ancillary services, and changing fleet compositions -- affect net revenues in this ERCOT-like system. In most production cost modeling exercises, resources are assumed to offer their marginal capabilities at marginal costs. Although this assumption is reasonable for feasibility studies and long-term planning, it does not adequately consider the market behaviors that impact revenue sufficiency. In this work, we simulate a limited set of market participant strategic bidding behaviors by means of different sets of markups; these markups are applied to the true production costs of all gas generators, which are the most prominent generators in ERCOT. Results show that markups can help generators increase their net revenues overall, although net revenues may increase or decrease depending on the technology and the year under study. Results also confirm that conventional, variable-cost-based production cost simulations do not capture prices accurately, and this particular feature calls for proxies for strategic behaviors (e.g., markups) and more accurate representations of how electricity markets work.

  10. Secure provision of reactive power ancillary services in competitive electricity markets

    El-Samahy, Ismael

    decoupled and assumed to be fixed during the reactive power dispatch procedures; however, the effect of reactive power on real power is considered in the model by calculating the required reduction in real power output of a generator due to an increase in its reactive power supply. In this case, real power generation is allowed to be rescheduled, within given limits, from the already dispatched levels obtained from the energy market clearing process. The proposed dispatch model achieves the main objective of an ISO in a competitive electricity market, which is to provide the required reactive power support from generators at least cost while ensuring a secure operation of the power system. The proposed reactive power procurement and dispatch models capture both the technical and economic aspects of power system operation in competitive electricity markets; however, from an optimization point of view, these models represent non-convex mixed integer non-linear programming (MINLP) problems due to the presence of binary variables associated with the different regions of reactive power operation in a synchronous generator. Such MINLP optimization problems are difficult to solve, especially for an actual power system. A novel Generator Reactive Power Classification (GRPC) algorithm is proposed in this thesis to address this issue, with the advantage of iteratively solving the optimization models as a series of non-linear programming (NLP) sub-problems. The proposed reactive power procurement and dispatch models are implemented and tested on the CIGRE 32-bus system, with several case studies that represent different practical operating scenarios. The developed models are also compared with other approaches for reactive power provision, and the results demonstrate the robustness and effectiveness of the proposed model. The results clearly reveal the main features of the proposed models for optimal provision of reactive power ancillary service, in order to suit the requirements of

  11. From a bundled energy-capacity pricing model to an energy-capacity-ancillary services pricing model

    In this paper, we extend the Chilean power generation pricing mechanism, with capacity and energy payments, to one where ancillary services (AS), as frequency regulation and voltage control, are explicitly recognized. Adequacy and security attributes of the electric system and the public good characteristics of AS are set within the payment structure to distribute the financing of AS among those who benefit from their provision. The contribution to finance the provision of AS is determined assessing the value assigned to the system security by each agent, following what's an efficient pricing mechanism in the presence of public goods

  12. Active Power Control of Wind Turbines for Ancillary Services: A Comparison of Pitch and Torque Control Methodologies

    Aho, Jacob; Fleming, Paul; Pao, Lucy Y.

    2016-08-01

    As wind energy generation becomes more prevalent in some regions, there is increased demand for wind power plants to provide ancillary services, which are essential for grid reliability. This paper compares two different wind turbine control methodologies to provide active power control (APC) ancillary services, which include derating or curtailing power generation, providing automatic generation control (AGC), and providing primary frequency control (PFC). The torque APC controller provides all power control through the power electronics whereas the pitch APC controller uses the blade pitch actuators as the primary means of power control. These controllers are simulated under various wind conditions with different derating set points and AGC participation levels. The metrics used to compare their performance are the damage equivalent loads (DELs) induced on the structural components and AGC performance metrics, which are used to determine the payments for AGC services by system operators in the United States. The simulation results show that derating the turbine reduces structural loads for both control methods, with the APC pitch control providing larger reductions in DELs, lower AGC performance scores, and higher root-mean-square pitch rates. Providing AGC increases the structural loads when compared to only derating the turbine, but even the AGC DELs are generally lower than those of the baseline control system. The torque APC control methodology also allows for more sustained PFC responses under certain derating conditions.

  13. A framework for cost-based pricing of transmission and ancillary services in competitive electric power markets

    In this paper the authors propose a framework for accurate cost determination and pricing of transmission and ancillary services in competitive electric power markets. The proposed framework is based on their anticipation of the evolving environment and industry structure. They envision the future as a competitive energy market with a centralized control entity that coordinates system activities, prices transmission and ancillary services and controls various system resources. This control entity has control over a certain (pre-defined) geographical area. It is proposed that the system operation and control be kept as they are currently done in control centers, no major change in these functions is required for the proposed pricing strategy. The pricing strategy is divided into two main classes based on time scale separation and firmness, short and long term, firm and interruptible contracts. The approach is based on superposition of different transaction on the network, and a three-part tariff design. The charges are directly related to the impact of each transaction on the system

  14. Three utilization patterns of the renovated Moste hydro power plant on an electricity market of power and ancillary services

    In addition to electricity, most hydro power plants can offer also the ancillary services: secondary and tertiary control reserve. On emerging electricity markets the need for these additional services is becoming more and more important, recognised and also paid. However, for each plant, there is some interdependence among those options. The same plant cannot provide maximal peaking electricity, maximal secondary control reserve as well as maximal tertiary control reserve at the same time. The generation capabilities of the plant must thus be partitioned properly among those options so as to achieve some overall goal (e.g. the maximum of revenue, etc.). This article briefly presents those options for the renovated Moste cascade on the upper Sava river near Bled in Slovenia. A small but effective mixed integer linear programme has been used.

  15. The business of medicine: how to overcome financial obstacles and secure financing for your private practice and ancillary services business.

    Nayor, David

    2012-01-01

    Doctors across the country who operate private medical practices are facing increasing financial obstacles, namely shrinking income as a result of rising costs and lower reimbursements. In addition, as hospitals have become overburdened many physicians have opened up private surgical centers; magnetic resonance imaging and computed tomography and positron emission tomography scanning facilities; pathology labs; colonoscopy/endoscopy suites; lithotripsy centers; and other medical businesses typically performed within the hospital. Moreover, many doctors seek loans to purchase existing practices or for their capital contribution in medical partnerships. The past decade has thus seen a significant increase in the number of doctors taking out small business loans. Indeed, banks view the healthcare industry as a large growth market. This article includes practical information, advice, and resources to help doctors to secure bank financing for their practices, ancillary services business, real estate, and equipment on the best possible market terms.

  8. Smart microgrid hierarchical frequency control ancillary service provision based on virtual inertia concept: An integrated demand response and droop controlled distributed generation framework

    Highlights: • Detailed formulation of the microgrid static and dynamic securities based on droop control and virtual inertia concepts. • Constructing a novel objective function using frequency excursion and rate of change of frequency profiles. • Ensuring the microgrid security subject to the microgrid economic and environmental policies. • Coordinated management of demand response and droop controlled distributed generation resources. • Precise scheduling of day-ahead hierarchical frequency control ancillary services using a scenario based stochastic programming. - Abstract: Low inertia stack, high penetration levels of renewable energy source and great ratio of power deviations in a small power delivery system put microgrid frequency at risk of instability. On the basis of the close coupling between the microgrid frequency and system security requirements, procurement of adequate ancillary services from cost-effective and environmental friendly resources is a great challenge requests an efficient energy management system. Motivated by this need, this paper presents a novel energy management system that is aimed to coordinately manage the demand response and distributed generation resources. The proposed approach is carried out by constructing a hierarchical frequency control structure in which the frequency dependent control functions of the microgrid components are modeled comprehensively. On the basis of the derived modeling, both the static and dynamic frequency securities of an islanded microgrid are provided in primary and secondary control levels. Besides, to cope with the low inertia stack of islanded microgrids, novel virtual inertia concept is devised based on the precise modeling of droop controlled distributed generation resources. The proposed approach is applied to typical test microgrid. Energy and hierarchical reserve resource are scheduled precisely using a scenario-based stochastic programming methodology. Moreover, analyzing the

    2006-06-01

    The European Southern Observatory (ESO) is in the process of creating a central access point for all services offered to its user community via the Web. That gateway, called the User Portal, will provide registered users with a personalized set of service access points, the actual set depending on each user's privileges. Correspondence between users and ESO will take place by way of "profiles", that is, contact information. Each user may have several active profiles, so that an investigator may choose, for instance, whether their data should be delivered to their own address or to a collaborator. To application developers, the portal will offer authentication and authorization services, either via database queries or an LDAP server. The User Portal is being developed as a Web application using Java-based technology, including servlets and JSPs.

  11. Improving service accessibility in service-oriented HIS.

    Babamir, Seyed Morteza; Arabfard, Masoud

    2012-12-01

    Nowadays, new trend in design and implementation of Hospital Information System (HIS) is towards using Web-based Service-Oriented Architecture (SOA). However, the standard SOA includes an insensitive service store through which the accessibility of some hospital services becomes difficult when their specification or network address are changed or missed. This paper discusses problems of insensitive service store and then presents a model where a sensitive service store is used to mitigate the problems. To show the efficiency of the proposed model, HIS of the Shahid Beheshti Hospital of Kashan including information systems of Admission, Outpatient, Ward, Pharmacy, Medical Document, Discharge and Insurance was designed and implemented with sensitive service store and its performance was considered.

  18. NASA Alternate Access to Station Service Concept

    Bailey, M. D.; Crumbly, C.

    2002-01-01

    The evolving nature of the NASA space enterprise compels the agency to develop new and innovative space systems concepts. NASA, working with increasingly strained budgets and a declining manpower base, is attempting to transform from operational activities to procurement of commercial services. NASA's current generation reusable launch vehicle, the Shuttle, is in transition from a government owned and operated entity to a commercial venture to reduce the civil servant necessities for that program. NASA foresees its second generation launch vehicles being designed and operated by industry for commercial and government services. The "service" concept is a pioneering effort by NASA. The purpose the "service" is not only to reduce the civil servant overhead but will free up government resources for further research and enable industry to develop a space business case so that industry can sustain itself beyond government programs. In addition, NASA desires a decreased responsibility thereby decreasing liability. The Second Generation Reusable Launch Vehicle (RLV) program is implementing NASA's Space Launch Initiative (SLI) to enable industry to develop the launch vehicles of the future. The Alternate Access to Station (AAS) project office within this program is chartered with enabling industry to demonstrate an alternate access capability for the International Space Station (ISS). The project will not accomplish this by traditional government procurement methods, not by integrating the space system within the project office, or by providing the only source of business for the new capability. The project funds will ultimately be used to purchase a service to take re-supply cargo to the ISS, much the same as any business might purchase a service from FedEx to deliver a package to its customer. In the near term, the project will fund risk mitigation efforts for enabling technologies. AAS is in some ways a precursor to the 2nd Generation RLV. By accomplishing ISS resupply

  6. Health services accessibility among Spanish elderly.

    Fernández-Mayoralas, G; Rodríguez, V; Rojo, F

    2000-01-01

    The paper aims to identify the variables that best explain the use of health services by people aged 65 and over in Spain. The data comes from the 1993 Spanish National Health Survey (ENSE 93). The conceptual framework is the model proposed by Andersen, who suggests that utilisation is a function of predisposition to use the services, the ability to use them and of need. A bivariate and multivariate analysis (SPSS-X Discriminant Procedure) is conducted to define the predictors that best discriminate users and non-users. The use of each health service is explained by a different set of variables. The need variables play a more important role in predicting the use of non-discretionary services that are more closely related to healing processes (medical consultations, emergencies and hospitalisation). The predisposing and enabling variables are more relevant in explaining the use of dental services, indicating a certain degree of inequity of these discretionary services. PMID:10622691

    2011-06-01

    Full Text Available Abstract Background Many bioinformatics algorithms and data sets are deployed using web services so that the results can be explored via the Internet and easily integrated into other tools and services. These services often include data from other sites that is accessed either dynamically or through file downloads. Developers of these services face several problems because of the dynamic nature of the information from the upstream services. Many publicly available repositories of bioinformatics data frequently update their information. When such an update occurs, the developers of the downstream service may also need to update. For file downloads, this process is typically performed manually followed by web service restart. Requests for information obtained by dynamic access of upstream sources is sometimes subject to rate restrictions. Findings SideCache provides a framework for deploying web services that integrate information extracted from other databases and from web sources that are periodically updated. This situation occurs frequently in biotechnology where new information is being continuously generated and the latest information is important. SideCache provides several types of services including proxy access and rate control, local caching, and automatic web service updating. Conclusions We have used the SideCache framework to automate the deployment and updating of a number of bioinformatics web services and tools that extract information from remote primary sources such as NCBI, NCIBI, and Ensembl. The SideCache framework also has been used to share research results through the use of a SideCache derived web service.

  13. Making Spatial Statistics Service Accessible On Cloud Platform

    Mu, X.; Wu, J.; Li, T.; Zhong, Y.; Gao, X.

    2014-04-01

    Web service can bring together applications running on diverse platforms, users can access and share various data, information and models more effectively and conveniently from certain web service platform. Cloud computing emerges as a paradigm of Internet computing in which dynamical, scalable and often virtualized resources are provided as services. With the rampant growth of massive data and restriction of net, traditional web services platforms have some prominent problems existing in development such as calculation efficiency, maintenance cost and data security. In this paper, we offer a spatial statistics service based on Microsoft cloud. An experiment was carried out to evaluate the availability and efficiency of this service. The results show that this spatial statistics service is accessible for the public conveniently with high processing efficiency.

  14. Unifying Access to National Hydrologic Data Repositories via Web Services

    Valentine, D. W.; Jennings, B.; Zaslavsky, I.; Maidment, D. R.

    2006-12-01

    The CUAHSI hydrologic information system (HIS) is designed to be a live, multiscale web portal system for accessing, querying, visualizing, and publishing distributed hydrologic observation data and models for any location or region in the United States. The HIS design follows the principles of open service oriented architecture, i.e. system components are represented as web services with well defined standard service APIs. WaterOneFlow web services are the main component of the design. The currently available services have been completely re-written compared to the previous version, and provide programmatic access to USGS NWIS. (steam flow, groundwater and water quality repositories), DAYMET daily observations, NASA MODIS, and Unidata NAM streams, with several additional web service wrappers being added (EPA STORET, NCDC and others.). Different repositories of hydrologic data use different vocabularies, and support different types of query access. Resolving semantic and structural heterogeneities across different hydrologic observation archives and distilling a generic set of service signatures is one of the main scalability challenges in this project, and a requirement in our web service design. To accomplish the uniformity of the web services API, data repositories are modeled following the CUAHSI Observation Data Model.

  15. 3PAC: Enforcing Access Policies for Web Services

    Bemmel, van J.; Wegdam, M.; Lagerberg, K.

    2005-01-01

    Web services fail to deliver on the promise of ubiquitous deployment and seamless interoperability due to the lack of a uniform, standards-based approach to all aspects of security. In particular, the enforcement of access policies in a service oriented architecture is not addressed adequately. We p

  16. Secure Access to Private Services in Intranet for Mobile Clients

    2013-02-01

    Full Text Available With wide adoption of Service Computing and Mobile Computing, people tend to invoke services with mobile devices, requiring accurate and real-time feedback from services at any time and any place. Among these services, some are private to limited users and require identity authorization before use; hence secure access control in wireless network should be provided. To address the challenge, in this study, we propose the architecture and protocols of a system of access to private services for mobile clients, which combines the technologies of trusted computing, Diffie-Hellman key agreement protocol, digital certificate, DES data encryption algorithm and twice verification. We further show the implementation of the proposed system, in which we have realized the authentication and authorization of mobile clients and then secure data transfer between mobile clients in the unsafe Internet and private services in the Intranet.

  17. The Critical Role of Institutional Services in Open Access Advocacy

    Tomasz Neugebauer

    2013-06-01

    Full Text Available This paper examines the development of the Open Access movement in scholarly communication, with particular attention to some of the rhetorical strategies and policy mechanisms used to promote it to scholars and scientists. Despite the majority of journal publishers’ acceptance of author self-archiving practices, and the minimal time commitment required by authors to successfully self-archive their work in disciplinary or institutional repositories, the majority of authors still by and large avoid participation. The paper reviews the strategies and arguments used for increasing author participation in open access, including the role of open access mandates. We recommend a service-oriented approach towards increasing participation in open access, rather than rhetoric that speculates on the benefits that open access will have on text/data mining innovation. In advocating for open access participation, we recommend focusing on its most universal and tangible purpose: increasing public open (gratis access to the published results of publicly funded research. Researchers require strong institutional support to understand the copyright climate of open access self-archiving, user-friendly interfaces and useful metrics, such as repository usage statistics. We recommend that mandates and well-crafted and responsive author support services at universities will ultimately be required to ensure the growth of open access. We describe the mediated deposit service that was developed to support author self-archiving in Spectrum: Concordia University Research Repository. By comparing the number of deposits of non-thesis materials (e.g. articles and conference presentations that were accomplished through the staff-mediated deposit service to the number of deposits that were author-initiated, we demonstrate the relative significance of this service to the growth of the repository.

    Full Text Available Abstract Background Still picture transmission was performed using a telemedicine system in an Emergency Medical Service (EMS during a prospective, controlled trial. In this ancillary, retrospective study the quality and content of the transmitted pictures and the possible influences of this application on prehospital time requirements were investigated. Methods A digital camera was used with a telemedicine system enabling encrypted audio and data transmission between an ambulance and a remotely located physician. By default, images were compressed (jpeg, 640 x 480 pixels. On occasion, this compression was deactivated (3648 x 2736 pixels. Two independent investigators assessed all transmitted pictures according to predefined criteria. In cases of different ratings, a third investigator had final decision competence. Patient characteristics and time intervals were extracted from the EMS protocol sheets and dispatch centre reports. Results Overall 314 pictures (mean 2.77 ± 2.42 pictures/mission were transmitted during 113 missions (group 1. Pictures were not taken for 151 missions (group 2. Regarding picture quality, the content of 240 (76.4% pictures was clearly identifiable; 45 (14.3% pictures were considered “limited quality” and 29 (9.2% pictures were deemed “not useful” due to not/hardly identifiable content.

  20. Optimal Policies for Simultaneous Energy Consumption and Ancillary Service Provision for Flexible Loads under Stochastic Prices and No Capacity Reservation Constraint

    Kefayati, Mahdi; Baldick, Ross

    2014-01-01

    Flexible loads, i.e. the loads whose power trajectory is not bound to a specific one, constitute a sizable portion of current and future electric demand. This flexibility can be used to improve the performance of the grid, should the right incentives be in place. In this paper, we consider the optimal decision making problem faced by a flexible load, demanding a certain amount of energy over its availability period, subject to rate constraints. The load is also capable of providing Ancillary ...

    ABSTRACT:The characteristics of demand side resources, such as fast response and low cost, are very helpful to improve wind power penetration when they are utilized to provide ancillary services for the power system. Typically, industrial demand response resources have the advantages of large capacity, load stability and are easy to manage when they are compared with commerce and inhabitant users. As a result, industrial demand response resources are very suitable to deal with large-scale wind power integration. In order to have an in-depth study on the response mechanism of industrial loads to provide ancillary services, this paper chosen electrolytic aluminum and irrigation pumping station as two typical industrial power users and analyzed the ancillary services type which could be provided. Then, a multi-agent response modeling containing these two kinds of industrial loads and the grid was built based on multi-agent technology. The goal, structure and behavior strategies of each agent were explained in the paper. In the process of simulation, the grid companies could adjust the ancillary services price according to the response of industrial power consumers. The results show that the pricing strategy of ancillary services in this model can fully exploit the response potential of all types of industrial power users to provide ancillary services while satisfying their interests.%挖掘响应迅速且成本较低的需求侧资源为电力系统提供辅助服务,对促进风电消纳具有积极意义。工业需求响应资源与商业、居民等用户相比具有容量大、负荷稳定、易于管理等优势,在应对大规模风电接入等方面具有更明显的优势。为深入研究工业用户提供辅助服务的响应机理,在分析电解铝、灌溉泵站2类典型工业负荷提供辅助服务类型的基础上,基于多智能体技术,构建了包含电网及以上2类工业负荷的多智能体系统,阐述各类智能体的目标

  2. NASA's Eos ClearingHOuse: Integrating Access to Data Services

    Burnett, M. T.; Pfister, R.; Wichman, K.

    2002-12-01

    ECHO (The Earth Observing System (EOS) ClearingHOuse) is being developed to provide flexibility to NASA's EOS to better meet the needs of the science community. ECHO is a clearinghouse of metadata, representing the data offerings of participating data providers. ECHO is being built with the goal of being an enabling system: Enabling a variety of Data Providers to participate. Enabling access to an ever-changing variety of Earth Science Data. Enabling access to an ever-growing suite of services, provided by the Science Community, which improves the usefulness of this data, including the binding of those services to the data represented in the clearinghouse. The purpose of this enabling philosophy is to support current Science efforts, but also to give the opportunity for creative organizations and individuals to break the traditional paradigm for discovering and leveraging Earth Science Data and Services in completely new ways. This presentation will focus on ECHO's approach to integrating Data Services from varied Service Providers, and facilitating access to those services by the user community. ECHO can be viewed as a typical Service oriented architecture. The fundamental interactions that it supports are (abstractly) Publish, Find and Bind. ECHO provides interfaces and mechanisms that allow organizations to publish their services. Using these interfaces, Service Providers can effectively "plug-in" their capabilities. There are mechanisms that allow the correlation of their service to the data types in the clearinghouse. ECHO's user community can find, or discover, services through a separate set of interfaces. Bindings are the mechanisms that support the invocation of services by ECHO's user community. ECHO supports binding either directly between the user and the service provider, or indirectly by using ECHO as a Service Broker. ECHO is supporting all of these Service capabilities by leveraging the contemporary (and evolving) "standards" of Web Services. Web

    A randomized controlled trial of outpatient open-access physiotherapy was carried out at West Cornwall Hospital during 1979/80. The referral rate to consultant outpatient clinics for those patients offered open-access physiotherapy was considerably lower than for the control group (17 per cent and 56 per cent respectively). Patients using the service received physiotherapy promptly although this did not result in shorter treatments. Those of the control group who eventually received physiothe...

  4. A Service Access Security Control Model in Cyberspace

    Qianmu, Li; Jie, Yin; Jun, Hou; Jian, Xu; Hong, Zhang; Yong, Qi

    A service access control model in cyberspace is proposed, which provides a generalized and effective mechanism of security management with some items constraint specifications. These constraint specifications are organized to form a construction, and an enact process is proposed to make it scalable and flexible to meet the need of diversified service application systems in cyberspace. The model of this paper erases the downward information flow by extended rules of read/write, which is the breakthrough of the limitations when applying the standard role-based access control in cyberspace.

  8. Richmond Wellbeing Service Access Strategy for Older Adults

    Gowling, Sarah; Persson, Jennie; Holt, Genevieve; Ashbourne, Sue; Bloomfield, James; Shortland, Hannah; Bate, Clare

    2016-01-01

    IAPT (Improving Access to Psychological Therapies) is a national programme aimed at increasing availability of evidence based psychological therapies in the NHS. IAPT is primarily for people who have mild to moderate, common mental health difficulties such as depression, anxiety, phobias and post traumatic stress disorder (PTSD). The programme seeks to use the least intrusive method of care possible to treat people at the time when it will be of most help to them. Individuals are able to self-refer into most IAPT services or alternatively can request to be referred by their GP or other services in the community. Richmond Wellbeing Service (RWS) is one such IAPT Service and this research is based on our work to promote accessibility of the service to one of the harder to reach population groups - older adults. We know that IAPT services could have a positive impact on older adults as it is believed on average, 25% of over 65 year olds face common mental health problems. However, only a third of these people discuss this with their GP and so are less likely to be referred to an IAPT Service. In relation to the above, this project was designed to look at increasing access for older adults into Richmond Wellbeing Service (RWS) specifically to improve access to the RWS by older adults by 100. The overall goal was to increase older adult (65+) referral rates by 20% over a year, in raw number this would translate to an increase of 100 over a year period, and in percentage terms an average of 8% of total referrals. Results yielded an increase of 39 referrals between baseline and test period. The majority of this increase had occurred in the final five months of the projects duration(31). Interestingly the number of older adults in the older age band (85+) almost doubled within this period (from 12 to 21). In total, in percentage terms this translates to an an increase of OA referrals from 6% up to 6.7%, as above we are aiming for 8% or an additional increase of 61 patients

    2012-10-15

    Nigeria experiences a remarkable paradox -- the abundance of energy resources and widespread energy poverty. Only about 40% of the population has access to the country’s grid electricity. About 72% of the population depends on traditional fuelwood for cooking. Despite this, government financing of energy services that benefits majority of Nigeria’s population has been grossly inadequate. Private sector investments and donor support have not fared better. This paper examines the current level of energy poverty in Nigeria. It analyses the level of government, private sector and donor funding for energy services that benefit the poor. It further reviews international best practices in expanding access for pro poor energy services. The paper finds a significant decline in political interest for expanding electricity services to rural areas. Even though ambitious policy reforms have commenced, agreed programmes are not implemented effectively. Not only are investments in rural electrification in decline, there is no history of annual budgeting for cooking energy programmes. The paper recommends a number of action points for expanding access to energy services that benefit the poor. These include the development and launching of a new national rural electrification strategy; establishment of a national cooking energy programme; and the development of clear policy incentives to support private sector investment in energy services for the poor. It calls on the Nigerian Central Bank of Nigeria to set aside 10% of the existing power intervention fund for pro poor energy financing; and the Nigerian Electricity Regulatory Commission to establish a clear framework for the utilization of the Consumer Assistance Fund. Other recommendations include the use of a proportion of the Ecological Fund to finance cooking energy; establishment of a donor’s platform on pro poor energy; and the mobilization of civil society in providing community-level energy services.

    2012-05-01

    Full Text Available Abstract Background Often new arrivals from refugee backgrounds have experienced poor health and limited access to healthcare services. The maternal and child health (MCH service in Victoria, Australia, is a joint local and state government operated, cost-free service available to all mothers of children aged 0–6 years. Although well-child healthcare visits are useful in identifying health issues early, there has been limited investigation in the use of these services for families from refugee backgrounds. This study aims to explore experiences of using MCH services, from the perspective of families from refugee backgrounds and service providers. Methods We used a qualitative study design informed by the socioecological model of health and a cultural competence approach. Two geographical areas of Melbourne were selected to invite participants. Seven focus groups were conducted with 87 mothers from Karen, Iraqi, Assyrian Chaldean, Lebanese, South Sudanese and Bhutanese backgrounds, who had lived an average of 4.7 years in Australia (range one month-18 years. Participants had a total of 249 children, of these 150 were born in Australia. Four focus groups and five interviews were conducted with MCH nurses, other healthcare providers and bicultural workers. Results Four themes were identified: facilitating access to MCH services; promoting continued engagement with the MCH service; language challenges; and what is working well and could be done better. Several processes were identified that facilitated initial access to the MCH service but there were implications for continued use of the service. The MCH service was not formally notified of new parents arriving with young children. Pre-arranged group appointments by MCH nurses for parents who attended playgroups worked well to increase ongoing service engagement. Barriers for parents in using MCH services included access to transportation, lack of confidence in speaking English and making

  15. SERVICE AVAILABILITY AND ACCESSIBILITY OF REQUIREMENTS USINGCLUSTERING IN CLOUD ENVIRONMENT

    Thamilvaani Arvaree Alvar

    2012-01-01

    Full Text Available Cloud computing is one contemporary technology in which the research community has recently embarked. Cloud computing faces many of the challenges and difficulties. Meeting the user needs is the important issue in any business environment. The need for quality services that satisfies both customers and service providers is very essential. Lacking of guarantees for the customer to fully satisfy with the retrieved services from the service provider for the requested requirements has been identified as the major problem statement of this study. Clustering is one of the methods that widely used in data mining especially for information retrieval. Information retrieval is a process of group similar content or files together. There are different algorithms available to do the clustering such as partitioned clustering (K-means Clustering and Hierarchical Clustering (Agglomerative Hierarchical Clustering (AHC. Due to large amount of data efficient access and exploration of information retrieval is always critical. Most of the time, user will get a long list of documents which is partially match their requirements. While searching for services or access the service, there are many irrelevant documents returned with the relevant document which meets the requirements. Therefore, clustering will be used to overcome the above problem. This technique will implemented in an application to efficiently assess the correctness (fitness of requirements measurement for the required services in cloud computing. The results or findings from the application will be the evidence to ensure meeting customer requirements more adequately while providing services. Reducing the inadequacy of meeting requirements will be the major contribution of this research with the support of the application.

  16. A SOAP Web Service for accessing MODIS land product subsets

    SanthanaVannan, Suresh K [ORNL; Cook, Robert B [ORNL; Pan, Jerry Yun [ORNL; Wilson, Bruce E [ORNL

    2011-01-01

    Remote sensing data from satellites have provided valuable information on the state of the earth for several decades. Since March 2000, the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on board NASA s Terra and Aqua satellites have been providing estimates of several land parameters useful in understanding earth system processes at global, continental, and regional scales. However, the HDF-EOS file format, specialized software needed to process the HDF-EOS files, data volume, and the high spatial and temporal resolution of MODIS data make it difficult for users wanting to extract small but valuable amounts of information from the MODIS record. To overcome this usability issue, the NASA-funded Distributed Active Archive Center (DAAC) for Biogeochemical Dynamics at Oak Ridge National Laboratory (ORNL) developed a Web service that provides subsets of MODIS land products using Simple Object Access Protocol (SOAP). The ORNL DAAC MODIS subsetting Web service is a unique way of serving satellite data that exploits a fairly established and popular Internet protocol to allow users access to massive amounts of remote sensing data. The Web service provides MODIS land product subsets up to 201 x 201 km in a non-proprietary comma delimited text file format. Users can programmatically query the Web service to extract MODIS land parameters for real time data integration into models, decision support tools or connect to workflow software. Information regarding the MODIS SOAP subsetting Web service is available on the World Wide Web (WWW) at http://daac.ornl.gov/modiswebservice.

  3. Access of rural AFDC Medicaid beneficiaries to mental health services.

    Lambert, D; Agger, M S

    1995-01-01

    This article examines geographic differences in the use of mental health services among Aid to Families with Dependent Children (AFDC)-eligible Medicaid beneficiaries in Maine. Findings indicate that rural AFDC beneficiaries have significantly lower utilization of mental health services than urban beneficiaries. Specialty mental health providers account for the majority of ambulatory visits for both rural and urban beneficiaries. However, rural beneficiaries rely more on primary-care providers than do urban beneficiaries. Differences in use are largely explained by variations in the supply of specialty mental health providers. This finding supports the long-held assumption that lower supply is a barrier to access to mental health services in rural areas. PMID:10153467

  4. Towards Emulation-as-a-Service: Cloud Services for Versatile Digital Object Access

    Dirk von Suchodoletz

    2013-06-01

    Full Text Available The changing world of IT services opens the chance to more tightly integrate digital long-term preservation into systems, both for commercial and end users. The emergence of cloud offerings re-centralizes services, and end users interact with them remotely through standardized (web-client applications on their various devices. This offers the chance to use partially the same concepts and methods to access obsolete computer environments and allows for more sustainable business processes. In order to provide a large variety of user-friendly remote emulation services, especially in combination with authentic performance and user experience, a distributed system model and architecture is required, suitable to run as a cloud service, allowing for the specialization both of memory institutions and third party service providers.The shift of the usually non-trivial task of the emulation of obsolete software environments from the end user to specialized providers can help to simplify digital preservation and access strategies. Besides offering their users better access to their holdings, libraries and archives may gain new business opportunities to offer services to a third party, such as businesses requiring authentic reproduction of digital objects and processes for legal reasons. This paper discusses cloud concepts as the next logical step for accessing original digital material. Emulation-as-a-Service (EaaS fills the gap between the successful demonstration of emulation strategies as a long term access strategy and it’s perceived availability and usability. EaaS can build upon the ground of research and prototypical implementations of previous projects, and reuse well established remote access technology.In this article we develop requirements and a system model, suitable for a distributed environment. We will discuss the building blocks of the core services as well as requirements regarding access management. Finally, we will try to present a

The main reason of not using contraception mostly because they want to have children 27.0% in urban, 28.2% rural whereas, the second reason is the fear of side effects 23.1% in urban, 16.5% rural. There is 10% of respondent did not use contraceptives, because they did not need it. Health seeking behavior of pregnant women with family planning work status has a significant relationship (prevalence ratio 1.073. The jobless mothers has better access to family planning services compared to working mother. Conclusions: Accessibility of family planning services is inadequate, because not all rural ‘Poskesdes’ equipped with infrastructure and family planning devices, a lack of knowledge of family planning in rural areas. Health seeking behavior of family planning services is mostly to the midwives, the scond is to community health centers and than polindes, ‘poskesdes’ as the ranks third.

  6. A JEE RESTful service to access Conditions Data in ATLAS

    Formica, Andrea; Gallas, E. J.

    2015-12-01

    Usage of condition data in ATLAS is extensive for offline reconstruction and analysis (e.g. alignment, calibration, data quality). The system is based on the LCG Conditions Database infrastructure, with read and write access via an ad hoc C++ API (COOL), a system which was developed before Run 1 data taking began. The infrastructure dictates that the data is organized into separate schemas (assigned to subsystems/groups storing distinct and independent sets of conditions), making it difficult to access information from several schemas at the same time. We have thus created PL/SQL functions containing queries to provide content extraction at multi-schema level. The PL/SQL API has been exposed to external clients by means of a Java application providing DB access via REST services, deployed inside an application server (JBoss WildFly). The services allow navigation over multiple schemas via simple URLs. The data can be retrieved either in XML or JSON formats, via simple clients (like curl or Web browsers).

  10. Web Services Provide Access to SCEC Scientific Research Application Software

    Gupta, N.; Gupta, V.; Okaya, D.; Kamb, L.; Maechling, P.

    2003-12-01

    Web services offer scientific communities a new paradigm for sharing research codes and communicating results. While there are formal technical definitions of what constitutes a web service, for a user community such as the Southern California Earthquake Center (SCEC), we may conceptually consider a web service to be functionality provided on-demand by an application which is run on a remote computer located elsewhere on the Internet. The value of a web service is that it can (1) run a scientific code without the user needing to install and learn the intricacies of running the code; (2) provide the technical framework which allows a user's computer to talk to the remote computer which performs the service; (3) provide the computational resources to run the code; and (4) bundle several analysis steps and provide the end results in digital or (post-processed) graphical form. Within an NSF-sponsored ITR project coordinated by SCEC, we are constructing web services using architectural protocols and programming languages (e.g., Java). However, because the SCEC community has a rich pool of scientific research software (written in traditional languages such as C and FORTRAN), we also emphasize making existing scientific codes available by constructing web service frameworks which wrap around and directly run these codes. In doing so we attempt to broaden community usage of these codes. Web service wrapping of a scientific code can be done using a "web servlet" construction or by using a SOAP/WSDL-based framework. This latter approach is widely adopted in IT circles although it is subject to rapid evolution. Our wrapping framework attempts to "honor" the original codes with as little modification as is possible. For versatility we identify three methods of user access: (A) a web-based GUI (written in HTML and/or Java applets); (B) a Linux/OSX/UNIX command line "initiator" utility (shell-scriptable); and (C) direct access from within any Java application (and with the

    Ancillary experiments' are a new technique whereby researchers use a completed experiment conducted by others to recover causal estimates of a randomized intervention on new outcomes. The method requires pairing new outcome data with randomized treatments the researchers themselves did not oversee. Since ancillary experiments rely on interventions that have already been undertaken, oftentimes by governments, they can provide a low-cost method with which to identify the effects of large-scale ...

  12. Ancillary Benefits of Climate Policy

    The benefits of climate policy normally consist exclusively of the reduced impacts of climate change, i.e., the policy’s primary aim. Our analysis of benefits of climate policy suggests, however, that researchers and policymakers should also take account of ancillary benefits, e.g., in the shape of improved air quality induced by climate protection measures. A consideration of both, primary and ancillary benefits, has a positive influence on global climate protection efforts, e.g., because th...

    Third party access to postal networks can be made subject to a range of access conditions. While the pricing of postal network access has received much research attention, the effects of access on quality of service have received less. Using data on international postal services in a large panel of European countries, we estimate an econometric model of average time-to-delivery for letter post, including a range of access conditions. We find that several access conditions have a significant a...

    An increasing number of information systems integrate semantic data stores for managing ontologies. To access these knowledge bases most of the available implementations provide application programming interfaces (APIs). The implementations of these APIs normally do not support any kind of network protocol or service interface. This works fine as long as a monolithic system is developed. If the need arises to integrate such a knowledge base into a service-oriented architecture a different app...

  19. Pilot evaluation of a web-based intervention targeting sexual health service access.

    Brown, K E; Newby, K; Caley, M; Danahay, A; Kehal, I

    2016-04-01

    Sexual health service access is fundamental to good sexual health, yet interventions designed to address this have rarely been implemented or evaluated. In this article, pilot evaluation findings for a targeted public health behavior change intervention, delivered via a website and web-app, aiming to increase uptake of sexual health services among 13-19-year olds are reported. A pre-post questionnaire-based design was used. Matched baseline and follow-up data were identified from 148 respondents aged 13-18 years. Outcome measures were self-reported service access, self-reported intention to access services and beliefs about services and service access identified through needs analysis. Objective service access data provided by local sexual health services were also analyzed. Analysis suggests the intervention had a significant positive effect on psychological barriers to and antecedents of service access among females. Males, who reported greater confidence in service access compared with females, significantly increased service access by time 2 follow-up. Available objective service access data support the assertion that the intervention may have led to increases in service access. There is real promise for this novel digital intervention. Further evaluation is planned as the model is licensed to and rolled out by other local authorities in the United Kingdom. PMID:26928566

  2. A Collaborative Wireless Access to On-Demand Services

    Zohar Naor

    2008-02-01

    Full Text Available A collaborative access scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. The key idea is that individual clients requesting for the same content can collaborate and share the same data channel. As opposed to broadcasting, this method enables the clients to determine online the delivered content, and thus supports on-demand services. On the other hand, a multicast content delivery is much more efficient than a unicast content distribution, which must use a dedicated data channel per each and every client. This method is particularly suitable for sessions having a long-time duration, for applications in which clients can subscribe to ahead of time, and for applications in which the clients receive the same information simultaneously. A multicast content distribution increases the network service throughput in terms of the expected number of clients served simultaneously, and therefore it offers a reduced waiting time for content delivery at highly loaded time periods. It is shown that the problem of maximizing the efficiency of distributing a content in a wireless network is NP-hard. An approximation algorithm is therefore used, that for any 0<ε<1 finds an approximation solution with a relative accuracy ε. The proposed method does not require any hardware modification on the network equipment. Thus, it can be easily implemented.

  3. Resolving mobility constraints impeding rural seniors' access to regionalized services.

    Ryser, Laura; Halseth, Greg

    2012-01-01

    Rural and small town places in developed economies are aging. While attention has been paid to the local transportation needs of rural seniors, fewer researchers have explored their regional transportation needs. This is important given policies that have reduced and regionalized many services and supports. This article explores mobility constraints impeding rural seniors' access to regionalized services using the example of northern British Columbia. Drawing upon several qualitative studies, we explore geographical, maintenance, organizational, communication, human resources, infrastructure, and financial constraints that affect seniors' regional mobility. Our findings indicate that greater coordination across multiple government agencies and jurisdictions is needed and more supportive policies and resources must be in place to facilitate a comprehensive regional transportation strategy. In addition to discussing the complexities of these geographies, the article identifies innovative solutions that have been deployed in northern British Columbia to support an aging population. This research provides a foundation for developing a comprehensive understanding of the key issues that need to be addressed to inform strategic investments in infrastructure and programs that support the regional mobility and, hence, healthy aging of rural seniors.

    2002-04-01

    This study discussed the ancillary spending that would be incurred by the Yukon Government as a result of the Alaska Highway Pipeline Project. Ancillary spending refers to investment that is needed to facilitate pipeline construction but is not directly related to the pipeline. It includes investment in roads and highways, water treatment, sewage and solid waste, air transportation, rail transportation (including the White Pass and the Canadian Arctic Railway), port development, schools, health services, and jails. It was determined that ancillary expenditures to the Yukon Government excluding health and correctional services is estimated at $6.95 to $7.85 million in pre-pipeline construction. During the 3 years of pipeline construction and the first 3 years of pipeline operation, the ancillary spending is not expected to be greater than $21.7 million. Ancillary spending includes the need to repair existing facilities and infrastructures after the pipeline is completed. This will provide employment for a variety of skilled people including engineers and trades people. Other developments associated with the AHPP may include gas field and mining development as well as developments in local gas and electricity distribution. 4 refs., 1 tab.

  9. Access Control Mechanisms for Semantic Web services-A Discussion on Requirements & Future Directions

    Gondara, Mandeep Kaur

    2011-01-01

    Semantic Web is an open, distributed, and dynamic environment where access to resources cannot be controlled in a safe manner unless the access decision takes into account during discovery of web services. Security becomes the crucial factor for the adoption of the semantic based web services. An access control means that the users must fulfill certain conditions in order to gain access over web services. Access control is important in both perspectives i.e. legal and security point of view. This paper discusses important requirements for effective access control in semantic web services which have been extracted from the literature surveyed. I have also discussed open research issues in this context, focusing on access control policies and models in this paper.

  10. Spatial analysis of elderly access to primary care services

    Lozano-Gracia Nancy

    2006-05-01

    Full Text Available Abstract Background Admissions for Ambulatory Care Sensitive Conditions (ACSCs are considered preventable admissions, because they are unlikely to occur when good preventive health care is received. Thus, high rates of admissions for ACSCs among the elderly (persons aged 65 or above who qualify for Medicare health insurance are signals of poor preventive care utilization. The relevant geographic market to use in studying these admission rates is the primary care physician market. Our conceptual model assumes that local market conditions serving as interventions along the pathways to preventive care services utilization can impact ACSC admission rates. Results We examine the relationships between market-level supply and demand factors on market-level rates of ACSC admissions among the elderly residing in the U.S. in the late 1990s. Using 6,475 natural markets in the mainland U.S. defined by The Health Resources and Services Administration's Primary Care Service Area Project, spatial regression is used to estimate the model, controlling for disease severity using detailed information from Medicare claims files. Our evidence suggests that elderly living in impoverished rural areas or in sprawling suburban places are about equally more likely to be admitted for ACSCs. Greater availability of physicians does not seem to matter, but greater prevalence of non-physician clinicians and international medical graduates, relative to U.S. medical graduates, does seem to reduce ACSC admissions, especially in poor rural areas. Conclusion The relative importance of non-physician clinicians and international medical graduates in providing primary care to the elderly in geographic areas of greatest need can inform the ongoing debate regarding whether there is an impending shortage of physicians in the United States. These findings support other authors who claim that the existing supply of physicians is perhaps adequate, however the distribution of them across

    1999-01-01

    Full Text Available We examine the service mechanism of two queueing models with two units in tandem. In the first model, customers who complete service in Unit 1 must wait in an intermediate buffer until the ongoing service in Unit II ends. In the second model, jobs can be pre-positioned in an intermediate buffer to await service in Unit II. Under the assumption of phase-type service times, the steady-state regime of the service system is studied in detail.

    California has undertaken a major restructuring of its electricity utility sector. Most electricity is now sold in open markets operated by the PX and other entities. Bilateral contracting among some market participants is also permitted. A group of independent generating companies bids into these markets together with out of state resources. In addition to these markets, CAISO operates markets for both imbalance energy and AS, a quite unusual feature of the California system. These markets were initially quite chaotic and were rife with market power problems. However, various reforms have now created a system that functions well. During the restructuring process, special provisions were made to protect public purpose programs, including renewable generation.

    2014-12-01

    Full Text Available OBJECTIVE To assess the inequalities in access, utilization, and quality of health care services according to the socioeconomic status. METHODS This population-based cross-sectional study evaluated 2,927 individuals aged ≥ 20 years living in Pelotas, RS, Southern Brazil, in 2012. The associations between socioeconomic indicators and the following outcomes were evaluated: lack of access to health services, utilization of services, waiting period (in days for assistance, and waiting time (in hours in lines. We used Poisson regression for the crude and adjusted analyses. RESULTS The lack of access to health services was reported by 6.5% of the individuals who sought health care. The prevalence of use of health care services in the 30 days prior to the interview was 29.3%. Of these, 26.4% waited five days or more to receive care and 32.1% waited at least an hour in lines. Approximately 50.0% of the health care services were funded through the Unified Health System. The use of health care services was similar across socioeconomic groups. The lack of access to health care services and waiting time in lines were higher among individuals of lower economic status, even after adjusting for health care needs. The waiting period to receive care was higher among those with higher socioeconomic status. CONCLUSIONS Although no differences were observed in the use of health care services across socioeconomic groups, inequalities were evident in the access to and quality of these services.

    With the mutual consent to use WSDL (Web Service Description Language) to describe web service interfaces and SOAP as the basic communication protocol, the cornerstone for web service-oriented architecture (WSOA) has been established. Considering the momentum observable by the growing number of specifications in the web service domain for the indispensable cross-cutting concern of identity management (IdM) it is still an open issue how a WSOA-aware IdM architecture is built and how it is link...

  7. Semantic Data Access Services at NASA's Atmospheric Science Data Center

    Huffer, E.; Hertz, J.; Kusterer, J.

    2012-12-01

    The corpus of Earth Science data products at the Atmospheric Science Data Center at NASA's Langley Research Center comprises a widely heterogeneous set of products, even among those whose subject matter is very similar. Two distinct data products may both contain data on the same parameter, for instance, solar irradiance; but the instruments used, and the circumstances under which the data were collected and processed, may differ significantly. Understanding the differences is critical to using the data effectively. Data distribution services must be able to provide prospective users with enough information to allow them to meaningfully compare and evaluate the data products offered. Semantic technologies - ontologies, triple stores, reasoners, linked data - offer functionality for addressing this issue. Ontologies can provide robust, high-fidelity domain models that serve as common schema for discovering, evaluating, comparing and integrating data from disparate products. Reasoning engines and triple stores can leverage ontologies to support intelligent search applications that allow users to discover, query, retrieve, and easily reformat data from a broad spectrum of sources. We argue that because of the extremely complex nature of scientific data, data distribution systems should wholeheartedly embrace semantic technologies in order to make their data accessible to a broad array of prospective end users, and to ensure that the data they provide will be clearly understood and used appropriately by consumers. Toward this end, we propose a distribution system in which formal ontological models that accurately and comprehensively represent the ASDC's data domain, and fully leverage the expressivity and inferential capabilities of first order logic, are used to generate graph-based representations of the relevant relationships among data sets, observational systems, metadata files, and geospatial, temporal and scientific parameters to help prospective data consumers

  8. A Service Oriented Architecture for Personalized Universal Media Access

    Ingo Brunkhorst

    2011-04-01

    Full Text Available Multimedia streaming means delivering continuous data to a plethora of client devices. Besides the actual data transport, this also needs a high degree of content adaptation respecting the end users’ needs given by content preferences, transcoding constraints, and device capabilities. Such adaptations can be performed in many ways, usually on the media server. However, when it comes to content editing, like mixing in subtitles or picture-in-picture composition, relying on third party service providers may be necessary. For economic reasons this should be done in a service-oriented way, because a lot of adaptation modules can be reused within different adaptation workflows. Although service-oriented architectures have become widely accepted in the Web community, the multimedia environment is still dominated by monolithic systems. The main reason is the insufficient support for working with continuous data: generally the suitability of Web services for handling complex data types and state-full applications is still limited. In this paper we discuss extensions of Web service frameworks, and present a first implementation of a service-oriented framework for media streaming and digital item adaptation. The focus lies on the technical realization of the services. Our experimental results show the practicality of the actual deployment of service-oriented multimedia frameworks.

  10. IVOA Recommendation: SimpleDALRegExt: Describing Simple Data Access Services

    Plante, Raymond; Harrison, Paul; Tody, Doug

    2014-01-01

    An application that queries or consumes descriptions of VO resources must be able to recognize a resource's support for standard IVOA protocols. This specification describes how to describe a service that supports any of the four fundamental data access protocols -- Simple Cone Search (SCS), Simple Image Access (SIA), Simple Spectral Access (SSA), Simple Line Access (SLA) -- using the VOResource XML encoding standard. A key part of this specification is the set of VOResource XML extension schemas that define new metadata that are specific to those protocols. This document describes in particular rules for describing such services within the context of IVOA Registries and data discovery as well as the VO Standard Interface (VOSI) and service self-description. In particular, this document spells out the essential markup needed to identify support for a standard protocol and the base URL required to access the interface that supports that protocol.

  11. Accessibility to primary health care services in the state of Goiás

    Juliana Pires Ribeiro

    2015-09-01

    Full Text Available The objective of this study was to evaluate accessibility to primary health care services in the state of Goiás. A descriptive cross-sectional study was conducted based on secondary data from the National Program to Improve Access to and Quality of Primary Health Care. The study sample was composed of health professionals from 1,216 primary health care units. Results showed that 68.5% of the health units miss a screening room, thus considerably damaging prompt decision-making by professionals. The lack of medical offices in 2% of the sites hinders the primary health care services accessibility in Goiás. As regards opening hours and work shifts, 86% of the units are open five days a week in eight-hour shifts, which does not favor accessibility for users. This study confirms the lack of accessibility to health services and the need for additional investments to strengthen primary health care.

  14. Implementation of levels of services on broadband networks with cable modem access

    Campos, Luis A.; Yu, Che-Fn

    1997-10-01

    Residential broadband access networks using technologies such as ADSL and cable modems have enabled the provisioning of emerging Internet applications such as Internet telephony, video conferencing and interactive games. These applications have specific end-to-end performance requirements from the network in order to have an acceptable performance. Currently the Internet is a best effort network which doesn't provide levels of service. There are many elements of an end-to-end network which are currently suitable to provide quality-of- service guaranties such as ATM links. Nevertheless, only with recent deployments of broadband access technologies and the introduction of Internet protocols such as RSVP, providing levels of service becomes feasible without the use expensive links to the customer site. This paper examines several network implementation options for introducing levels of service using cable modem access. Limitations imposed by the applications on the network as well as the contribution of the different network elements to level of service parameters such as end-to-end delay, throughput and jitter are examined. Concentration network architectures as well as proposed backbone configuration options for end-to-end level of service provisioning are presented. At the access network, provisioning of level of service using bandwidth control through packet throttling and through access network design providing excess bandwidth to customers are presented. HFC protocol dependent means to provide level of services including reservation and ATM based protocols are examined as well.

  17. AccessMod 3.0: computing geographic coverage and accessibility to health care services using anisotropic movement of patients

    Ebener Steeve

    2008-12-01

    Full Text Available Abstract Background Access to health care can be described along four dimensions: geographic accessibility, availability, financial accessibility and acceptability. Geographic accessibility measures how physically accessible resources are for the population, while availability reflects what resources are available and in what amount. Combining these two types of measure into a single index provides a measure of geographic (or spatial coverage, which is an important measure for assessing the degree of accessibility of a health care network. Results This paper describes the latest version of AccessMod, an extension to the Geographical Information System ArcView 3.×, and provides an example of application of this tool. AccessMod 3 allows one to compute geographic coverage to health care using terrain information and population distribution. Four major types of analysis are available in AccessMod: (1 modeling the coverage of catchment areas linked to an existing health facility network based on travel time, to provide a measure of physical accessibility to health care; (2 modeling geographic coverage according to the availability of services; (3 projecting the coverage of a scaling-up of an existing network; (4 providing information for cost effectiveness analysis when little information about the existing network is available. In addition to integrating travelling time, population distribution and the population coverage capacity specific to each health facility in the network, AccessMod can incorporate the influence of landscape components (e.g. topography, river and road networks, vegetation that impact travelling time to and from facilities. Topographical constraints can be taken into account through an anisotropic analysis that considers the direction of movement. We provide an example of the application of AccessMod in the southern part of Malawi that shows the influences of the landscape constraints and of the modes of transportation on

  3. Web service activities at the IRIS DMC to support federated and multidisciplinary access

    Trabant, Chad; Ahern, Timothy K.

    2013-04-01

    At the IRIS Data Management Center (DMC) we have developed a suite of web service interfaces to access our large archive of, primarily seismological, time series data and related metadata. The goals of these web services include providing: a) next-generation and easily used access interfaces for our current users, b) access to data holdings in a form usable for non-seismologists, c) programmatic access to facilitate integration into data processing workflows and d) a foundation for participation in federated data discovery and access systems. To support our current users, our services provide access to the raw time series data and metadata or conversions of the raw data to commonly used formats. Our services also support simple, on-the-fly signal processing options that are common first steps in many workflows. Additionally, high-level data products derived from raw data are available via service interfaces. To support data access by researchers unfamiliar with seismic data we offer conversion of the data to broadly usable formats (e.g. ASCII text) and data processing to convert the data to Earth units. By their very nature, web services are programmatic interfaces. Combined with ubiquitous support for web technologies in programming & scripting languages and support in many computing environments, web services are very well suited for integrating data access into data processing workflows. As programmatic interfaces that can return data in both discipline-specific and broadly usable formats, our services are also well suited for participation in federated and brokered systems either specific to seismology or multidisciplinary. Working within the International Federation of Digital Seismograph Networks, the DMC collaborated on the specification of standardized web service interfaces for use at any seismological data center. These data access interfaces, when supported by multiple data centers, will form a foundation on which to build discovery and access mechanisms

  4. Accessing the SEED Genome Databases via Web Services API: Tools for Programmers

    Vonstein Veronika

    2010-06-01

    Full Text Available Abstract Background The SEED integrates many publicly available genome sequences into a single resource. The database contains accurate and up-to-date annotations based on the subsystems concept that leverages clustering between genomes and other clues to accurately and efficiently annotate microbial genomes. The backend is used as the foundation for many genome annotation tools, such as the Rapid Annotation using Subsystems Technology (RAST server for whole genome annotation, the metagenomics RAST server for random community genome annotations, and the annotation clearinghouse for exchanging annotations from different resources. In addition to a web user interface, the SEED also provides Web services based API for programmatic access to the data in the SEED, allowing the development of third-party tools and mash-ups. Results The currently exposed Web services encompass over forty different methods for accessing data related to microbial genome annotations. The Web services provide comprehensive access to the database back end, allowing any programmer access to the most consistent and accurate genome annotations available. The Web services are deployed using a platform independent service-oriented approach that allows the user to choose the most suitable programming platform for their application. Example code demonstrate that Web services can be used to access the SEED using common bioinformatics programming languages such as Perl, Python, and Java. Conclusions We present a novel approach to access the SEED database. Using Web services, a robust API for access to genomics data is provided, without requiring large volume downloads all at once. The API ensures timely access to the most current datasets available, including the new genomes as soon as they come online.

  1. An interaction-based access control model (IBAC) for collaborative services

    Altunay, Mine; /Fermilab; Byrd, Gregory T.; Brown, Doug E.; Dean, Ralph A.; /North Carolina State U.

    2008-04-01

    A collaboration is a collection of services that work together to achieve a common goal. Although collaborations help when tackling difficult problems, they lead to security issues. First, a collaboration is often performed by services that are drawn from different security domains. Second, a service interacts with multiple peer services during the collaboration. These interactions are not isolated from one another--e.g., data may flow through a sequence of different services. As a result, a service is exposed to multiple peer services in varying degrees, leading to different security threats. We identify the types of interactions that can be present in collaborations, and discuss the security threats due to each type. We propose a model for representing the collaboration context so that a service can be made aware of the existing interactions. We provide an access control model for a service participating in a collaboration. We couple our access control model with a policy model, so that the access requirements from collaborations can be expressed and evaluated.

    2007-10-01

    Full Text Available Abstract Background International research shows that injecting drug users (IDUs can encounter many barriers when they try to access drug treatment and other services. However, the existing literature is mostly quantitative and does not consider the kinds of factors that injectors themselves identify as enabling them to access and benefit from services. Responding to this gap in knowledge, our paper explores IDUs' own suggestions for improving service engagement and their reports of other factors enabling them to seek help. Methods Semi-structured qualitative interviews were conducted with 75 current illicit drug injectors in three geographically diverse areas of West Yorkshire, England. Recruitment was through needle exchange programmes, with additional snowball sampling to ensure inclusivity of gender, ethnicity and primary drug injected. Transcribed data were analysed thematically using Framework. Results Although participants were often satisfied with current access to services, they made three broad suggestions for improving engagement. These were: providing more services (more providers and more forms of support; better operation of existing services (including better communication systems and more flexibility around individual needs; and staffing-related improvements (particularly, less judgemental and more understanding staff attitudes. Other factors identified as important enablers of help seeking were: having supporting relationships (particularly with family members; personal circumstances/life events (especially becoming a parent; and an injector's state of mind (such as feeling motivated and positive. Conclusion A range of practical suggestions for improving IDUs' access to drug treatment and other services are identified.

    2015-06-01

    Full Text Available This study assessed the association between accessibility of catering service venues and adolescents’ alcohol use over the previous 30 days. The data were collected from cross-sectional surveys conducted in 2014, 2223 students at 27 high schools in Chaoyang and Xicheng districts, Beijing using self-administered questionnaires to collect the adolescents information on socio-demographic characteristics and recent alcohol experiences. The accessibility of, and proximity to, catering service venues were summarized by weights, which were calculated by multiplication of the type-weight and the distance-weight. All sampled schools were categorized into three subgroups (low, middle, and high geographic density based on the tertile of nearby catering service venues, and a multi-level logistic regression analysis was performed to explore variance between the school levels. Considering the setting characteristics, the catering service venues weighted value was found to account for 8.6% of the school level variance of adolescent alcohol use. The odds ratios (OR and 95% confidence intervals (CI of drinking over the past 30-days among adolescents with medium and high accessibility of catering service venues were 1.17 (0.86, 1.57 and 1.47 (1.06, 2.02, respectively (p < 0.001 for trend test. This study addressed a gap in the adolescent drinking influence by the catering service venues around schools in China. Results suggest that the greater accessibility of catering service venues around schools is associated with a growing risk of recent drinking.

  5. A Semantic Context-Based Model for MobileWeb Services Access Control

    Haibo Shen

    2011-02-01

    Full Text Available As mobile web services becomes more pervasive, applications based on mobile web services will need flexible access control mechanisms. Unlike traditional approaches based on the identity or role for access control, access decisions for these applications will depend on the combination of the required attributes of users and the contextual information. This paper proposes a semantic context-based access control model (called SCBAC to be applied in mobile web services environment by combining semantic web technologies with context-based access control mechanism. The proposed model is a context-centric access control solutions, context is the first-class principle that explicitly guides both policy specification and enforcement process. In order to handle context information in the model, this paper proposes a context ontology to represent contextual information and employ it in the inference engine. As well as, this paper specifies access control policies as rules over ontologies representing the concepts introduced in the SCBAC model, and uses semantic web rule language (SWRL to form policy rule and infer those rules by JESS inference engine. The proposed model can also be applied to context-aware applications.

  6. Government policy and access to natural gas service in Canada

    As part of the Canadian energy policy between the mid-1970's to the mid-1980's, consumers were encouraged to use fuels alternative to oil. The first set of policy issues involved measures to provide consumers with incentives to switch to non-oil-burning equipment, whereas the second set of. policy papers emphasized the expansion of the natural gas distribution system. More than $1 billion have been spent on the gas pipeline expansion project. Consequences of program expenditures in each province were examined. With the exception of Manitoba, it was found that annual net pipeline additions were higher during the program period, indicating that the program policies induced these activities to occur sooner than if the policies were not in place. Kilometres of gas pipeline per individual constructed was highest in Quebec, where construction proceeded mainly between the more densely populated centres. In contrast, in Saskatchewan and Alberta, the program encouraged natural gas pipeline construction in rural areas with lower populations. Without the program, these areas may not have had access to natural gas for a very long time. It was concluded that, in this, and some other instances, public investment had the effect of accelerating developments, or encouraging the completion of projects that otherwise would not have been undertaken. It was suggested that in the future decision-makers consider the costs of changes in activity patterns prior to designing such programs. 2 figs., 1 table

  7. Data Access Services interoperability in the Geosciences by means of the GI-axe Brokering Framework

    Boldrini, Enrico; Santoro, Mattia; Papeschi, Fabrizio; Nativi, Stefano

    2013-04-01

    Many software tools are in use in the different Geosciences domains to the aim of publishing, accessing, evaluating and using available datasets in a service based environment. These tools/services are often domain-specific and usually support a small and disciplinary set of protocols and data models. On the other hand, multidisciplinary applications need to access many of these tools/services belonging to different domains in order to retrieve heterogeneous datasets (e.g. satellite acquired gridded coverages and in-situ sensor time series), then "uniformly process them" and achieve a deeper insight. Moreover datasets, to be easily processed, should be available according to a given Common Grid Environment (CGE): i.e. a geospatial environment characterized by a common spatio-temporal CRS (Coordinate Reference System), resolution, extension and by a common format encoding. Now, the interoperability effort needed by multidisciplinary applications is ordinarily in charge of data providers servers or user clients: in both cases, this represents a high entry barrier. The GI-axe Access Broker addresses this interoperability issue by taking charge of the needed implementation effort. It acts as an intermediation service between the User Clients and the Data Provider Services, placing itself in a third party (Broker) Layer. Indeed the Access Broker can access datasets available through well known access services in use by the Geosciences communities (e.g. OGC WCS, WMS, WFS, OPeNDAP, FTP, REST APIs, …) and republish them according to the application client interfaces. Moreover, GI-axe transforms datasets according to the a CGE specified by Users. In doing so it may resort to external processing services already in use by the community, supplementing the functionalities already supported by the data provider services. The external processing services list can be configured by Users. GI-axe is also a flexible framework, composed of extensible components. This architecture

    2015-02-01

    Full Text Available Background: Inequalities in healthcare between population groups of South Africa existed during the apartheid era and continue to exist both between and within many population groups. Accessibility and affordability of healthcare is a human right.Objectives: The aim of the study was to explore and describe accessibility, affordability and the use of health services by the mixed race (coloured population in the Western Cape, South Africa.Method: A cross-sectional descriptive, non-experimental study with a quantitative approach was applied. A purposive convenient sample of 353 participants (0.6% was drawn from a population of 63 004 economically-active people who lived in the residential areas as defined for the purpose of the study. All social classes were represented. The hypothesis set was that there is a positive relationship between accessibility, affordability and the use of health services. A pilot study was conducted which also supported the reliability and validity of the study. Ethics approval was obtained from the University of Stellenbosch and informed consent from respondents. A questionnaire was used to collect the data.Results: The hypothesis was accepted. The statistical association between affordability (p = < 0.01, accessibility (p = < 0.01 and the use of health services was found to be significant using the Chi-square (χ² test.Conclusion: The study has shown how affordability and accessibility may influence the use of healthcare services. Accessibility is not only the distance an individual must travel to reach the health service point but more so the utilisation of these services. Continuous Quality Management should be a priority in healthcare services, which should be user-friendly.

  10. Programmatic access to data and information at the IRIS DMC via web services

    Weertman, B. R.; Trabant, C.; Karstens, R.; Suleiman, Y. Y.; Ahern, T. K.; Casey, R.; Benson, R. B.

    2011-12-01

    The IRIS Data Management Center (DMC) has developed a suite of web services that provide access to the DMC's time series holdings, their related metadata and earthquake catalogs. In addition, services are available to perform simple, on-demand time series processing at the DMC prior to being shipped to the user. The primary goal is to provide programmatic access to data and processing services in a manner usable by and useful to the research community. The web services are relatively simple to understand and use and will form the foundation on which future DMC access tools will be built. Based on standard Web technologies they can be accessed programmatically with a wide range of programming languages (e.g. Perl, Python, Java), command line utilities such as wget and curl or with any web browser. We anticipate these services being used for everything from simple command line access, used in shell scripts and higher programming languages to being integrated within complex data processing software. In addition to improving access to our data by the seismological community the web services will also make our data more accessible to other disciplines. The web services available from the DMC include ws-bulkdataselect for the retrieval of large volumes of miniSEED data, ws-timeseries for the retrieval of individual segments of time series data in a variety of formats (miniSEED, SAC, ASCII, audio WAVE, and PNG plots) with optional signal processing, ws-station for station metadata in StationXML format, ws-resp for the retrieval of instrument response in RESP format, ws-sacpz for the retrieval of sensor response in the SAC poles and zeros convention and ws-event for the retrieval of earthquake catalogs. To make the services even easier to use, the DMC is developing a library that allows Java programmers to seamlessly retrieve and integrate DMC information into their own programs. The library will handle all aspects of dealing with the services and will parse the returned

    William Dubinski; Leighl, Natasha B.; Ming-Sound Tsao; David M. Hwang

    2012-01-01

    The pathologic diagnosis of lung cancer historically has relied primarily on morphologic features of tumors in histologic sections. With the emergence of new targeted therapies, the pathologist is called upon increasingly to provide not only accurate typing of lung cancers, but also to provide prognostic and predictive information, based on a growing number of ancillary tests, that may have significant impact on patient management. This review provides an overview of ancillary tests currently...

  12. Access to general practitioner services amongst underserved Australians: a microsimulation study

    Schofield Deborah J

    2012-01-01

    Full Text Available Abstract Background One group often identified as having low socioeconomic status, those living in remote or rural areas, are often recognised as bearing an unequal burden of illness in society. This paper aims to examine equity of utilisation of general practitioner services in Australia. Methods Using the 2005 National Health Survey undertaken by the Australian Bureau of Statistics, a microsimulation model was developed to determine the distribution of GP services that would occur if all Australians had equal utilisation of health services relative to need. Results It was estimated that those who are unemployed would experience a 19% increase in GP services. Persons residing in regional areas would receive about 5.7 million additional GP visits per year if they had the same access to care as Australians residing in major cities. This would be a 18% increase. There would be a 20% increase for inner regional residents and a 14% increase for residents of more remote regional areas. Overall there would be a 5% increase in GP visits nationally if those in regional areas had the same access to care as those in major cities. Conclusion Parity is an insufficient goal and disadvantaged persons and underserved areas require greater access to health services than the well served metropolitan areas due to their greater poverty and poorer health status. Currently underserved Australians suffer a double disadvantage: poorer health and poorer access to health services.

  13. Remote information service access system based on a client-server-service model

    Konrad, Allan M.

    1996-01-01

    A local host computing system, a remote host computing system as connected by a network, and service functionalities: a human interface service functionality, a starter service functionality, and a desired utility service functionality, and a Client-Server-Service (CSS) model is imposed on each service functionality. In one embodiment, this results in nine logical components and three physical components (a local host, a remote host, and an intervening network), where two of the logical components are integrated into one Remote Object Client component, and that Remote Object Client component and the other seven logical components are deployed among the local host and remote host in a manner which eases compatibility and upgrade problems, and provides an illusion to a user that a desired utility service supported on a remote host resides locally on the user's local host, thereby providing ease of use and minimal software maintenance for users of that remote service.

  16. Addressing Service Access Barriers for Homeless Youth: A Call for Collaboration

    Jeffrey L. PERRON

    2014-06-01

    Full Text Available Homeless youth are among the most vulnerable individuals in North American society. The day-to-day stressors they face while living on the streets pose a great threat to their mental and physical health. A number of barriers that youth face in accessing care have been identified in the literature. This discussion article highlights work that has been done to apply geographic theory to issues of service access among homeless youth. To date, most such work has been theoretical in nature, with collaborations between geographers and homeless youth researchers to make applied recommendations for the location of services. Urban geographers and homeless youth researchers are implored to collaborate in order to make recommendations that will increase the access to service, particularly for rural homeless youth.

  17. Satisfaction with Access to Health Services: The Perspective of Estonian Patients with Rheumatoid Arthritis

    Kaja Põlluste

    2012-01-01

    Full Text Available In this cross-sectional study we explained the possible determinants of satisfaction with access to health services in patients with rheumatoid arthritis (RA. Of the 2000 randomly selected Estonian adult patients with RA, a total 1259 completed the survey. Regression analysis was used to analyse the predictors of patients' satisfaction with access to health services. Half of the respondents were satisfied with their access to health services. Factors that had a negative impact on satisfaction included pain intensity, longer waiting times to see the doctors, as well as low satisfaction with the doctors. Transportation costs to visit a rheumatologist and higher rehabilitation expenses also affected the degree of satisfaction. Patients who could choose the date and time at which they could visit the rheumatologist or who could visit their “own” doctor were more likely to be satisfied than patients whose appointment times were appointed by a healthcare provider.

    Remote access to dynamically changing information elements is a required functionality for various network services, including routing and instances of context-sensitive networking. Three fundamentally different strategies for such access are investigated in this paper: (1) a reactive approach initiated by the requesting entity, and two versions of proactive approaches in which the entity that contains the information element actively propagates its changes to potential requesters, either (2)...

  1. Access to and use of infertility services in the United States: framing the challenges.

    Adashi, Eli Y; Dean, Laura A

    2016-05-01

    An overview of access to and use of general infertility and assisted reproductive technology (ART) services in the United States (U.S.) shows a declining trend for the ever-use of infertility services. Moreover, the use of ART services lags relative to other member nations of the Organization for Economic Co-operation and Development (OECD). Access to and use of general infertility and ART services is primarily undermined by a severely constrained underwriting universe dominated by self-insured employers and by a finite number of state infertility insurance mandates. The contribution of traditional public and private payers to the underwriting of ART is limited. As compared with OECD member nations wherein the access to and underwriting of general infertility and ART services is universal, the current status quo in the U.S. can only be characterized as dismal. Further, the current state of affairs is socially unjust in that the right to build a family in the face of infertility appears to have become a function of economic prowess. Given the dominance of the self-insured employers as underwriters of general infertility and ART services, advocacy directed at this interest group is likely to prove most productive. Improving the state of underwriting of general infertility and ART services in the U.S. must be embraced as a central moral imperative and as an unwavering strategic goal of the professional societies entrusted with the reproductive health of women and men.

  2. Living large: the experiences of large-bodied women when accessing general practice services

    Russell N

    2013-09-01

    Full Text Available INTRODUCTION: Numerous studies report high levels of stigma and discrimination experienced by obese/overweight women within the health care system and society at large. Despite general practice being the most utilised point of access for health care services, there is very little international or national exploration of the experiences of large-bodied women (LBW accessing these services. The aim of this study was to explore LBW's experiences of accessing general practice services in New Zealand. METHODS: This is a qualitative, descriptive, feminist study. Local advertising for participants resulted in eight self-identified, large-bodied women being interviewed. A post-structural feminist lens was applied to the data during thematic analysis. FINDINGS: The women in this study provided examples of verbal insults, inappropriate humour, negative body language, unmet health care needs and breaches of dignity from health care providers in general practice. Seven themes were identified: early experiences of body perception, confronting social stereotypes, contending with feminine beauty ideals, perceptions of health, pursuing health, respecting the whole person, and feeling safe to access care. CONCLUSION: Pressure for body size vigilance has, in effect, excluded the women in this study from the very locations of health that they are 'encouraged' to attend-including socialising and exercising in public, screening opportunities that require bodily exposure, and accessing first point of care health services.

  3. Performance Issues Related to Web Service Usage for Remote Data Access

    Web services are starting to be widely used in applications for remotely accessing data. This is of special interest for research based on small and medium scale fusion devices, since scientists participating remotely to experiments are accessing large amounts of data over the Internet. Recent tests were conducted to see how the new network traffic, generated by the use of web services, can be integrated in the existing infrastructure and what would be the impact over existing applications, especially those used in a remote participation scenario

  5. Location- and Time-Dependent VPD for Privacy-Preserving Wireless Accesses to Cloud Services

    Yoon, Jong P

    2011-01-01

    The advent of smartphones in recent years has changed the wireless landscape. Smartphones have become a platform for online user interface to cloud databases. Cloud databases may provide a large set of user-private and sensitive data (i.e., objects), while smartphone users (i.e., subjects) provide location-sensitive information. Secure and private services in wireless accessing to cloud databases have been discussed actively for the past recent years. However, the previous techniques are unsatisfactory for dynamism of moving subjects' wireless accesses. In this paper, we propose a novel technique to dynamically generate virtual private databases (VPD) for each access by taking subjects' location and time information into account. The contribution of this paper includes a privacy-preserving access control mechanism for dynamism of wireless access.

  6. Access to eye health services among indigenous Australians: an area level analysis

    Kelaher Margaret

    2012-09-01

    Full Text Available Abstract Background This project is a community-level study of equity of access to eye health services for Indigenous Australians. Methods The project used data on eye health services from multiple sources including Medicare Australia, inpatient and outpatient data and the National Indigenous Eye Health Survey. The analysis focused on the extent to which access to eye health services varied at an area level according to the proportion of the population that was Indigenous (very low = 0-1.0%, low = 1.1-3.0%, low medium = 3.1-6.0%, high medium = 6.1-10.0%, high = 10.1-20.0%, very high = 20 + %. The analysis of health service utilisation also took into account age, remoteness and the Socioeconomic Indices for Areas (SEIFA. Results The rate of eye exams provided in areas with very high Indigenous populations was two-thirds of the rate of eye exams for areas with very low indigenous populations. The cataract surgery rates in areas with high medium to very high Indigenous populations were less than half that reference areas. In over a third of communities with very high Indigenous populations the cataract surgery rate fell below the World Health Organization (WHO guidelines compared to a cataract surgery rate of 3% in areas with very low Indigenous populations. Conclusions There remain serious disparities in access to eye health service in areas with high Indigenous populations. Addressing disparities requires a co-ordinated approach to improving Indigenous people’s access to eye health services. More extensive take-up of existing Medicare provisions is an important step in this process. Along with improving access to health services, community education concerning the importance of eye health and the effectiveness of treatment might reduce reluctance to seek help.

    2005-01-01

    The authors examine the impact of local politics and government structure on the allocation of publicly subsidized (SUS) health services across municipios (counties) in Brazil, and on the probability that uninsured individuals who require medical attention actually receive access to those health services. Using data from the 1998 PNAD survey they demonstrate that higher per capita levels of SUS doctors, nurses, and clinic rooms increase the probability that an uninsured individual gains acces...

  9. Disparities in Access to Easy-to-Use Services for Children with Special Health Care Needs.

    2016-05-01

    Objectives Families, clinicians and policymakers desire improved delivery of health and related services for children with special health care needs (CSHCN). We analyzed factors associated with ease of use in obtaining such services. We also explored what were specific difficulties or delays in receiving services. By examining data from the National Survey of Children with Special Health Care Needs (NS-CSHCN 2009-2010) and using the revised criteria for "ease of use," we were able to assess the percentage of parents who reported that their experiences seeking services for their children met those criteria. Methods We performed Chi square tests to examine associations between the independent variables and their relationship to the difficulties or delays assessed in the survey; including: eligibility, availability of services, waiting lists, cost, and access to information. We used logistic regression to determine the association of meeting the "ease of use" criteria with socio-demographic, complexity of need, and access variables. Results Overall, a third of families of CSHCN (35.3 %) encounter difficulties, delays, or frustrations in obtaining health and related services. The lack of access to health and community services in this study fell most heavily on children from racial/ethnic minority backgrounds, those in poverty, and those with complex emotional/behavioral or developmental needs and functional limitations. Conclusions for Practice CSHCN require services from a broad array of providers across multiple systems. Unfortunately, there are certain difficulties that hamper the accessibility of these systems. These findings underscore the need for both practice-level response and systems-level reform to ensure equitable distribution of health and community resources. PMID:26728898

  10. Are social franchises contributing to universal access to reproductive health services in low-income countries?

    Sundari Ravindran, T K; Fonn, Sharon

    2011-11-01

    A social franchise in health is a network of for-profit private health practitioners linked through contracts to provide socially beneficial services under a common brand. The early 21st century has seen considerable donor enthusiasm for promoting social franchises for the provision of reproductive health services. Based on a compendium of descriptive information on 45 clinical social franchises, located in 27 countries of Africa, Asia and Latin America, this paper examines their contribution to universal access to comprehensive reproductive health services. It finds that these franchises have not widened the range of reproductive health services, but have mainly focused on contraceptive services, and to a lesser extent, maternal health care and abortion. In many instances, coverage had not been extended to new areas. Measures taken to ensure sustainability ran counter to the objective of access for low-income groups. In almost two-thirds of the franchises, the full cost of all services had to be paid out of pocket and was unaffordable for low-income women. While standards and protocols for quality assurance were in place in all franchises, evidence on adherence to these was limited. Informal interviews with patients indicated satisfaction with services. However, factors such as difficulties in recruiting franchisees and significant attrition, franchisees' inability to attend training programmes, use of lay health workers to deliver services without support or supervision, and logistical problems with applying quality assurance tools, all raise concerns. The contribution of social franchises to universal access to reproductive health services appears to be uncertain. Continued investment in them for the provision of reproductive health services does not appear to be justified until and unless further evidence of their value is forthcoming. PMID:22118144

  11. Virtual queueing techniques for UBR+ service in ATM with fair access and minimum bandwidth guarantee

    Siu, K.Y.; Wu, Y.; Ren, W.

    1998-11-01

    The ATM Forum is currently discussing the need for a new best-effort service called UBR+, which is an enhancement to the existing UBR service, to support data traffic. The objective of the UBR+ service is to provide each user with a minimum service rate guarantee and a fair access to any excess available bandwidth. In this paper, the authors present a new efficient scheme for supporting this service. The key advantage of the scheme is that it employs only FIFO queueing (instead of per-VC queueing) and admits simple implementation in ATM switches. The ideas involve a simple scheduling mechanism that is based on per-VC queueing and incorporate the virtual queueing technique that can efficiently emulate per-VC queueing on a shared FIFO queue. Simulation results are presented to show that the schemes can deliver almost ideal performance for supporting the new service requirements of UBR+.

  12. Essays on the Impacts of Geography and Institutions on Access to Energy and Public Infrastructure Services

    Archibong, Belinda

    While previous literature has emphasized the importance of energy and public infrastructure services for economic development, questions surrounding the implications of unequal spatial distribution in access to these resources remain, particularly in the developing country context. This dissertation provides evidence on the nature, origins and implications of this distribution uniting three strands of research from the development and political economy, regional science and energy economics fields. The dissertation unites three papers on the nature of spatial inequality of access to energy and infrastructure with further implications for conflict risk , the historical institutional and biogeographical determinants of current distribution of access to energy and public infrastructure services and the response of households to fuel price changes over time. Chapter 2 uses a novel survey dataset to provide evidence for spatial clustering of public infrastructure non-functionality at schools by geopolitical zone in Nigeria with further implications for armed conflict risk in the region. Chapter 3 investigates the drivers of the results in chapter 2, exploiting variation in the spatial distribution of precolonial institutions and geography in the region, to provide evidence for the long-term impacts of these factors on current heterogeneity of access to public services. Chapter 4 addresses the policy implications of energy access, providing the first multi-year evidence on firewood demand elasticities in India, using the spatial variation in prices for estimation.

    2015-11-01

    Full Text Available Background: Despite the expansion of health services and community-based interventions in Ethiopia, limited evidence exists about the distribution of and access to health facilities and their relationship with the performance of tuberculosis (TB control programmes. We aim to assess the geographical distribution of and physical accessibility to TB control services and their relationship with TB case notification rates (CNRs and treatment outcome in the Sidama Zone, southern Ethiopia. Design: We carried out an ecological study to assess physical accessibility to TB control facilities and the association of physical accessibility with TB CNRs and treatment outcome. We collected smear-positive pulmonary TB (PTB cases treated during 2003–2012 from unit TB registers and TB service data such as availability of basic supplies for TB control and geographic locations of health services. We used ArcGIS 10.2 to measure the distance from each enumeration location to the nearest TB control facilities. A linear regression analysis was employed to assess factors associated with TB CNRs and treatment outcome. Results: Over a decade the health service coverage (the health facility–to-population ratio increased by 36% and the accessibility to TB control facilities also improved. Thus, the mean distance from TB control services was 7.6 km in 2003 (ranging from 1.8 to 25.5 km between kebeles (the smallest administrative units and had decreased to 3.2 km in 2012 (ranging from 1.5 to 12.4 km. In multivariate linear regression, as distance from TB diagnostic facilities (b-estimate=−0.25, p<0.001 and altitude (b-estimate=−0.31, p<0.001 increased, the CNRs of TB decreased, whereas a higher population density was associated with increased TB CNRs. Similarly, distance to TB control facilities (b-estimate=−0.27, p<0.001 and altitude (b-estimate=−0.30, p<0.001 were inversely associated with treatment success (proportion of treatment completed or cured cases

  6. Constraints and Benefits of Child Welfare Contracts with Behavioral Health Providers: Conditions that Shape Service Access.

    Bunger, Alicia C; Cao, Yiwen; Girth, Amanda M; Hoffman, Jill; Robertson, Hillary A

    2016-09-01

    This qualitative study examines worker perceptions of how public child welfare agencies' purchase of service contracts with private behavioral health organizations can both facilitate and constrain referral making and children's access to services. Five, 90-min focus groups were conducted with workers (n = 50) from an urban public child welfare agency in the Midwest. Using a modified grounded theory approach, findings suggest that contracts may expedite service linkages, but contract benefits are conditioned upon design and implementation. Results also suggest the critical role of front line workers in carrying out contractual relationships. Implications for research and interventions for enhancing contracting are discussed.

  7. From the voices of women: facilitating survivor access to IPV services.

    Simmons, Catherine A; Farrar, Melissa; Frazer, Kitty; Thompson, Mary Jane

    2011-10-01

    This mixed-method study investigated perceptions women domestic violence survivors/victims have about why women do not seek help from formal support structures and actions domestic helping agencies can take to facilitate survivor access to services. Congruent with previous research, quantitative analysis identified 17 reasons women do not seek help from formal support structures. Expanding current knowledge, concept mapping revealed six ways family violence programs can better reach women in abusive relationships, including (1) remove barriers to services, (2) improve comfort with services, (3) "talk about it," (4) improve community awareness, (5) victim-targeted marketing, and (6) "I honestly don't know."

    2014-01-01

    Objectives To investigate the effect of providing patients online access to their electronic health record (EHR) and linked transactional services on the provision, quality and safety of healthcare. The objectives are also to identify and understand: barriers and facilitators for providing online access to their records and services for primary care workers; and their association with organisational/IT system issues. Setting Primary care. Participants A total of 143 studies were included. 17 were experimental in design and subject to risk of bias assessment, which is reported in a separate paper. Detailed inclusion and exclusion criteria have also been published elsewhere in the protocol. Primary and secondary outcome measures Our primary outcome measure was change in quality or safety as a result of implementation or utilisation of online records/transactional services. Results No studies reported changes in health outcomes; though eight detected medication errors and seven reported improved uptake of preventative care. Professional concerns over privacy were reported in 14 studies. 18 studies reported concern over potential increased workload; with some showing an increase workload in email or online messaging; telephone contact remaining unchanged, and face-to face contact staying the same or falling. Owing to heterogeneity in reporting overall workload change was hard to predict. 10 studies reported how online access offered convenience, primarily for more advantaged patients, who were largely highly satisfied with the process when clinician responses were prompt. Conclusions Patient online access and services offer increased convenience and satisfaction. However, professionals were concerned about impact on workload and risk to privacy. Studies correcting medication errors may improve patient safety. There may need to be a redesign of the business process to engage health professionals in online access and of the EHR to make it friendlier and provide equity of

  10. Assessment of universal access to comprehensive sexual and reproductive health services in Egypt

    Doaa Oraby

    2015-09-01

    Full Text Available In 2005, a World Health Organization resolution called for health systems to move towards universal coverage, such that everyone would have access to promotive, preventive, curative and rehabilitative health interventions at an affordable cost. Responding to this call, a new target for achieving universal access to reproductive health was integrated within the revised millennium development goals framework. Forty-eight African countries adopted the Maputo Plan of Action committing to the goal of universal access to comprehensive sexual and reproductive health services in Africa by 2015. The aim of this study was to assess Egypt’s commitment to implementing the Maputo Plan of Action. This was achieved through soliciting information relating to the extent of Egypt’s progress towards the achievement of universal access to sexual and reproductive health and rights information and services. In late 2009, a qualitative study was conducted. It included in-depth interviews with 20 physicians and 10 key informants in addition to 8 focus group discussions with sub-segments of 65 beneficiaries, including married women of reproductive age, married men and youth of both sexes. The study revealed that public sector, non-governmental organisations and private sector organisations delivering sexual and reproductive health services functioned in isolation from each other. Delivered services focused mainly on family planning and maternity care and targeted married women of reproductive age. Scaling up universal access to sexual and reproductive health services requires programmes to expand beyond the maternal and child health delivery model targeted solely at married women with children.

  11. AX Tank Farm ancillary equipment study

    This report examines the feasibility of remediating ancillary equipment associated with the 241-AX Tank Farm at the Hanford Site. Ancillary equipment includes surface structures and equipment, process waste piping, ventilation components, wells, and pits, boxes, sumps, and tanks used to make waste transfers to/from the AX tanks and adjoining tank farms. Two remedial alternatives are considered: (1) excavation and removal of all ancillary equipment items, and (2) in-situ stabilization by grout filling, the 241-AX Tank Farm is being employed as a strawman in engineering studies evaluating clean and landfill closure options for Hanford single-shell tanks. This is one of several reports being prepared for use by the Hanford Tanks Initiative Project to explore potential closure options and to develop retrieval performance evaluation criteria for tank farms

  12. Access to general health care services by a New Zealand population with serious mental illness.

    Wheeler A

    2014-03-01

    Full Text Available INTRODUCTION: Literature suggests that good quality health care access can have a positive impact on the health of people with serious mental illness (SMI, but literature relating to patterns of access by this group is equivocal. AIM: This study was designed to explore health care access patterns in a group of people with SMI and to compare them with a general New Zealand population group, in order for health providers to understand how they might contribute to positive health outcomes for this group. METHODS: The study surveyed 404 mental health consumers aged 18-65 years receiving care from one district health board in Auckland about their patterns of health care access. Results were compared with those from the New Zealand Health Survey of the general population. RESULTS: Findings suggest that the SMI consumer respondents had poorer physical health than the general population respondents, accessed health care services in more complex ways and were more particular about who they accessed for their care than the general population respondents. There was some concern from SMI consumers around discrimination from health care providers. The study also suggested that some proactive management with SMI consumers for conditions such as metabolic syndrome was occurring within the health care community. DISCUSSION: The first point of access for SMI consumers with general health problems is not always the family general practitioner and so other health professionals may sometimes need to consider the mental and physical health of such consumers in a wider context than their own specialism.

  13. Access to diagnostics in primary care and the impact on a primary care led health service.

    O'Riordan, M

    2015-02-01

    We undertook a postal survey of GPs to establish their current access to radiological and endoscopic tests. More than one fifth of GPs do not have direct access to abdominal (n = 42, 21.4%) or pelvic (n = 49, 24.6%) ultrasound in the public system. Where access is available public patients have an average 14 week waiting period. In stark contrast in the private system virtually all GPs have direct access (n = 159, 99.2% and n = 156, 98.8% respectively for abdominal and pelvic ultrasound) with an average wait of just over four days. Direct access to CT scan in the public system is available to the minority of GPs, e.g. n = 31, 18.4% for chest scan, in the public system; even where available, there is an average 12 week wait for this. In comparison 151 (88.6%) GPs have access to CT chest scanning in the private sector with an average waiting time of 5.4 working days. Such limited access to diagnostics impacts on the delivery of a quality service.

    Motivated by the need to improve efficiency in the way earth scientists access information, IRIS has developed significant new cyberinfrastructure to allow access to all time series data at the IRIS DMC including the wealth of new observations generated as a part of EarthScope. Driven specifically by the USArray component of EarthScope, IRIS Data Services has also actively developed a wealth of new higher level products that serve as stepping stones to further research. These products are available either through the SPUD product management system or directly through web services. This presentation will highlight ways that web services simplify access to the time series information at the IRIS DMC, allow simple incorporation of data into scientist's workflows, provide limited preprocessing of data, as well as providing access to higher level products that can bridge the gap between disciplines as well as assisting seismologists in data selection. IRIS is actively promoting these web services techniques in other high profile projects sponsored by the National Science Foundation including both Cooperation between Europe and the United States (COOPEUS) project as well as within the NSF promoted EarthCube project. In both of these activities it is IRIS' goal to assist in the integration of data between earth science disciplines by leveraging the experience we have gained in our web service activities. Additionally IRIS will leverage web services to better provide research ready data sets. Such data sets will enable researchers to request data that are suitable for use in their specific research studies by comparing data quality attributes of the data to those that the researcher specifies are required in their work.

  15. A Flexible Component based Access Control Architecture for OPeNDAP Services

    Kershaw, Philip; Ananthakrishnan, Rachana; Cinquini, Luca; Lawrence, Bryan; Pascoe, Stephen; Siebenlist, Frank

    2010-05-01

    Network data access services such as OPeNDAP enable widespread access to data across user communities. However, without ready means to restrict access to data for such services, data providers and data owners are constrained from making their data more widely available. Even with such capability, the range of different security technologies available can make interoperability between services and user client tools a challenge. OPeNDAP is a key data access service in the infrastructure under development to support the CMIP5 (Couple Model Intercomparison Project Phase 5). The work is being carried out as part of an international collaboration including the US Earth System Grid and Curator projects and the EU funded IS-ENES and Metafor projects. This infrastructure will bring together Petabytes of climate model data and associated metadata from over twenty modelling centres around the world in a federation with a core archive mirrored at three data centres. A security system is needed to meet the requirements of organisations responsible for model data including the ability to restrict data access to registered users, keep them up to date with changes to data and services, audit access and protect finite computing resources. Individual organisations have existing tools and services such as OPeNDAP with which users in the climate research community are already familiar. The security system should overlay access control in a way which maintains the usability and ease of access to these services. The BADC (British Atmospheric Data Centre) has been working in collaboration with the Earth System Grid development team and partner organisations to develop the security architecture. OpenID and MyProxy were selected at an early stage in the ESG project to provide single sign-on capability across the federation of participating organisations. Building on the existing OPeNDAP specification an architecture based on pluggable server side components has been developed at the BADC

  16. Exploring inequalities in access to and use of maternal health services in South Africa

    Silal Sheetal P

    2012-05-01

    Full Text Available Abstract Background South Africa’s maternal mortality rate (625 deaths/100,000 live births is high for a middle-income country, although over 90% of pregnant women utilize maternal health services. Alongside HIV/AIDS, barriers to Comprehensive Emergency Obstetric Care currently impede the country’s Millenium Development Goals (MDGs of reducing child mortality and improving maternal health. While health system barriers to obstetric care have been well documented, “patient-oriented” barriers have been neglected. This article explores affordability, availability and acceptability barriers to obstetric care in South Africa from the perspectives of women who had recently used, or attempted to use, these services. Methods A mixed-method study design combined 1,231 quantitative exit interviews with sixteen qualitative in-depth interviews with women (over 18 in two urban and two rural health sub-districts in South Africa. Between June 2008 and September 2009, information was collected on use of, and access to, obstetric services, and socioeconomic and demographic details. Regression analysis was used to test associations between descriptors of the affordability, availability and acceptability of services, and demographic and socioeconomic predictor variables. Qualitative interviews were coded deductively and inductively using ATLAS ti.6. Quantitative and qualitative data were integrated into an analysis of access to obstetric services and related barriers. Results Access to obstetric services was impeded by affordability, availability and acceptability barriers. These were unequally distributed, with differences between socioeconomic groups and geographic areas being most important. Rural women faced the greatest barriers, including longest travel times, highest costs associated with delivery, and lowest levels of service acceptability, relative to urban residents. Negative provider-patient interactions, including staff inattentiveness, turning

  17. Perceived Barriers for Accessing Health Services among Individuals with Disability in Four African Countries.

    Arne H Eide

    Full Text Available There is an increasing awareness among researchers and others that marginalized and vulnerable groups face problems in accessing health care. Access problems in particular in low-income countries may jeopardize the targets set by the United Nations through the Millennium Development Goals. Thus, identifying barriers for individuals with disability in accessing health services is a research priority. The current study aimed at identifying the magnitude of specific barriers, and to estimate the impact of disability on barriers for accessing health care in general. A population based household survey was carried out in Sudan, Namibia, Malawi, and South Africa, including a total of 9307 individuals. The sampling strategy was a two-stage cluster sampling within selected geographical areas in each country. A listing procedure to identify households with disabled members using the Washington Group six screening question was followed by administering household questionnaires in households with and without disabled members, and questionnaires for individuals with and without disability. The study shows that lack of transport, availability of services, inadequate drugs or equipment, and costs, are the four major barriers for access. The study also showed substantial variation in perceived barriers, reflecting largely socio-economic differences between the participating countries. Urbanity, socio-economic status, and severity of activity limitations are important predictors for barriers, while there is no gender difference. It is suggested that education reduces barriers to health services only to the extent that it reduces poverty. Persons with disability face additional and particular barriers to health services. Addressing these barriers requires an approach to health that stresses equity over equality.

  18. Patients’ Online Access to Their Primary Care Electronic Health Records and Linked Online Services: Implications for Research and Practice

    Freda Mold

    2015-12-01

    Full Text Available Online access to medical records and linked services, including requesting repeat prescriptions and booking appointments, enables patients to personalize their access to care. However, online access creates opportunities and challenges for both health professionals and their patients, in practices and in research. The challenges for practice are the impact of online services on workload and the quality and safety of health care. Health professionals are concerned about the impact on workload, especially from email or other online enquiry systems, as well as risks to privacy. Patients report how online access provides a convenient means through which to access their health provider and may offer greater satisfaction if they get a timely response from a clinician. Online access and services may also result in unforeseen consequences and may change the nature of the patient-clinician interaction. Research challenges include: (1 Ensuring privacy, including how to control inappropriate carer and guardian access to medical records; (2 Whether online access to records improves patient safety and health outcomes; (3 Whether record access increases disparities across social classes and between genders; and (4 Improving efficiency. The challenges for practice are: (1 How to incorporate online access into clinical workflow; (2 The need for a business model to fund the additional time taken. Creating a sustainable business model for a safe, private, informative, more equitable online service is needed if online access to records is to be provided outside of pay-for-service systems.

  19. GROWTH OF SME SECTOR AND WAYS OF IMPROVING ACCESS TO FINANCIAL SERVICES IN UZBEKISTAN

    Turaboy Koraliev

    2014-04-01

    Full Text Available Private sector is recognized as the driving force and the engine for economic growth in many countries. It delivers important goods and services, provides jobs, generates revenue for public sector, and creates and maintains infrastructure. SMEs in particular create jobs and lead to more equitable distribution of incomes. In Uzbekistan the share of SMEs in GDP steadily increased from 30% in 2000 to 54% in 2012. The sector accounts for 75% of total employment in the country and it is forecasted that SMEs will add around half a million of new jobs in 2013.Despite these improvements, SMEs’ productivity and competitiveness potential have been affected by regulatory and institutional constraints. Access to adequate financial services is a key component for sustainable growth of the private sector, economic diversification and creation of more and better jobs. Adequate access to finance includes not only bank loans, but also a host of financing instruments that are geared to meet the diverse needs of enterprises and entrepreneurs with different characteristics and profiles. In addition, access to a broader range of efficient and reliable financial services, including electronic payment services, enables enterprises to manage the financial resources available to them more effectively.

    Quality Issue: Although costly and time consuming, videofluoroscopic swallowing (VFS) examinations are the gold standard for imaging of oro-pharyngeal dysphagia, and demand is likely to increase with an ageing population. Traditional radiologist-led VFS services in the UK are gradually being replaced by practitioner-led clinics undertaken jointly by speech and language therapists and radiographers. This article explores the impact on patient access of a practitioner-led VFS clinic at a large teaching hospital. Initial Assessment: Specific information pertaining to VFS patient waiting times and service quality was collected for a twelve month period both pre- and post-clinic formation. Choice of Solution: Additional capacity was achieved with the introduction of the practitioner-led clinic, with overall patient access improving by 111%. Mean waiting times for in-patients reduced by 75%, many of whom had the procedure on the same day as referral, with out-patients waiting times reducing by 62.5%. Evaluation: The data demonstrates that patient access and report turnaround times are significantly improved, with no adverse effects as measured by inadequate studies, incorrect reports, complaints and documented radiation dose levels. Lessons Learnt: Practitioner-led VFS services can be recommended as a safe and efficient method of improving service provision.

    2009-08-01

    Full Text Available Objective: To understand the characteristics of access to the General System of Social Security in health (SGSS, from the perspective of doctors, nurses, administrators and users. Methodology: based on the grounded theory we present a study in six cities in Colombia: Barranquilla, Bucaramanga, Bogota, Leticia, Medellín and Pasto, for which interviews were conducted in-depth with health professionals involved in service delivery and focus groups with service users. Results: The findings indicate that insurance has become an end in itself, and being affiliated to SGSSS does not guarantee effective access to services. The dominance of the market, the financial profitability of insurers, imposed cost-containment mechanisms over the right to health. There are limitations from the rules, benefit plans that create geographical, economic and cultural barriers from the various actors involved in the chain of decisions. Additionally, display individual and institutional ethical shortcomings, clientelism and corruption in the management of resources, coupled with poverty and geographical dispersion of communities, mean that further limiting access to health services.

    Olsen, Rasmus Løvenstein; Schwefel, Hans-Peter; Hansen, Martin Bøgsted

    2006-01-01

    Remote access to dynamically changing information elements is a required functionality for various network services, including routing and instances of context-sensitive networking. Three fundamentally different strategies for such access are investigated in this paper: (1) a reactive approach...... analytic models to compute different performance metrics for these approaches, with special focus on the so-called mismatch probability. The results of the analytic models allow for design decisions on which strategy to implement for specific input parameters (change rate of the information element...

    2012-09-01

    Full Text Available Abstract Background Immigration is not a new phenomenon but, rather, has deep roots in human history. Documents from every era detail individuals who left their homelands and struggled to reestablish their lives in other countries. The aim of this study was to explore and understand the experience of Iranian immigrants who accessed Canadian health care services. Research with immigrants is useful for learning about strategies that newcomers develop to access health care services. Methods The research question guiding this study was, “What are the processes by which Iranian immigrants learn to access health care services in Canada?” To answer the question, a constructivist grounded theory approach was applied. Initially, unstructured interviews were conducted with 17 participants (11 women and six men who were adults (at least 18 years old and had immigrated to Canada within the past 15 years. Eight participants took part in a second interview, and four participants took part in a third interview. Results Using a constructivist grounded theory approach, “tackling the stumbling blocks of access” emerged as the core category. The basic social process (BSP, becoming self-sufficient, was a transitional process and had five stages: becoming a stranger; feeling helpless; navigating/seeking information; employing strategies; and becoming integrated and self-sufficient. We found that “tackling the stumbling blocks of access” was the main struggle throughout this journey. Some of the immigrants were able to overcome these challenges and became proficient in accessing health care services, but others were unable to make the necessary changes and thus stayed in earlier stages/phases of transition, and sometimes returned to their country of origin. Conclusion During the course of this journey a substantive grounded theory was developed that revealed the challenges and issues confronted by this particular group of immigrants. This process explains

    SRUTHY.S

    2015-08-01

    Full Text Available Abstract-Broadband access networks have become an essential part of worldwide communication systems because of the exponential growth of broadband services such as video on demand high definition TV internet protocol TV and video conferencing. Exponential growth in the volume of wireless data boosted by the growing popularity of mobile devices such as smartphone and tablets has forced the telecommunication industries to rethink the way networks are currently designed and to focus on the development of high-capacity mobile broadband networks. In response to this challenge researchers have been working toward the development of an integrated wireless optical broadband access network. Two major candidate technologies which are currently known for their high capacity as well as quality of service QoS for multimedia traffic are passive optical networks PON and fourth generation 4G wireless networks. PON is a wired access technology well known for its cost efficiency and high capacity whereas 4G is a wireless broadband access technology which has achieved broad market acceptance because of its ease of deployment ability to offer mobility and its cost efficiency. Integration of PON and 4G technologies in the form of wireless-optical broadband access networks offers advantages such as extension of networks in rural areas support for mobile broadband services and quick deployment of broadband networks. These two technologies however have different design architectures for handling broadband services that require quality of service. For example 4G networks use traffic classification for supporting different QoS demands whereas the PON architecture has no such mechanism to differentiate between types of traffic. These two technologies also differ in their power saving mechanisms. Propose a service class mapping for the integrated PON-4G network which is based on the MG1 queuing model and class-based power saving mechanism which significantly improves the

  9. Gender, sexuality and the discursive representation of access and equity in health services literature: implications for LGBT communities

    MacDonnell Judith A

    2011-09-01

    Full Text Available Abstract Background This article considers how health services access and equity documents represent the problem of access to health services and what the effects of that representation might be for lesbian, gay, bisexual and transgender (LGBT communities. We conducted a critical discourse analysis on selected access and equity documents using a gender-based diversity framework as determined by two objectives: 1 to identify dominant and counter discourses in health services access and equity literature; and 2 to develop understanding of how particular discourses impact the inclusion, or not, of LGBT communities in health services access and equity frameworks.The analysis was conducted in response to public health and clinical research that has documented barriers to health services access for LGBT communities including institutionalized heterosexism, biphobia, and transphobia, invisibility and lack of health provider knowledge and comfort. The analysis was also conducted as the first step of exploring LGBT access issues in home care services for LGBT populations in Ontario, Canada. Methods A critical discourse analysis of selected health services access and equity documents, using a gender-based diversity framework, was conducted to offer insight into dominant and counter discourses underlying health services access and equity initiatives. Results A continuum of five discourses that characterize the health services access and equity literature were identified including two dominant discourses: 1 multicultural discourse, and 2 diversity discourse; and three counter discourses: 3 social determinants of health (SDOH discourse; 4 anti-oppression (AOP discourse; and 5 citizen/social rights discourse. Conclusions The analysis offers a continuum of dominant and counter discourses on health services access and equity as determined from a gender-based diversity perspective. The continuum of discourses offers a framework to identify and redress

    2015-03-01

    Full Text Available As the competent laws on Health and Education of the Extremaduran Government read, all the Extremaduran people have the right to their benefits, irrespective of their social, economic and cultural characteristics. Nevertheless, in the Region of Extremadura there are still differences between the rural and urban areas, so, studying how the Extremaduran people can access, with the same conditions, to those services considered basic, such as health and education, is very significant. Using techniques as Network Analyst and the interpolation method IDW, we can note that in Extremadura there are still zones with a very-far- from- laws reality, rural areas with a difficult access to the named services and equipment due to the location on low developed in population and economy areas, and very far from the main communication roads

  15. Characteristics of collaborative care in increasing access to mental health service in the Asian community.

    Sung, Jeehee; Mayo, Nicolle; Ko, Mei-Ju; Lasley, Chandra

    2013-09-01

    This study examined the use of thematic analysis to determine how characteristics of collaborative care facilitate accessibility to mental health services among the Asian community in the United States. This investigation explored characteristics of collaborative care in patient treatment, barriers that prevent the Asian community from utilizing care, and how collaborative settings can facilitate mental health care access in the Asian community. Mental health providers with relevant experiences in collaborative care were recruited through snowball sampling to participate in a telephone interview with the researchers. The results suggested a collectivistic culture, valuing authority, acculturation, language, and stigma as themes of Asian patients as well as key providers (mental and medical health providers), colocation, the physician's leading role, the provider's language, and collaboration among providers as themes for collaborative care. The study suggests that collaborative care's foundational characteristics can promote easier access to mental health care for the Asian community. PMID:23937434

  6. Improving territorial accessibility of mental health services: The case of Spain

    Enrique López-Lara

    2012-12-01

    Full Text Available Background and Objectives: Citizens choose their health care services not only depending on their needs, but also on where they are located. The location of the services is especially important in the case of mental health due to the specific features of mental disorders. This article provides an analysis of temporal access by road to outpatient mental health centres in Andalusia (Spain with a view to improving accessibility for the greatest volume of population possible. Methods: Firstly, accessibility by road to the outpatient mental health centres was calculated in terms of time by establishing journey times using the ArcGIS Geographical Information System´s (GIS Network Analyst module. These journey times by road enabled travel times to be established for these sections, temporal accessibility areas to be plotted from each of the outpatient mental health centres and the number of people included in each accessibility area to be calculated. Results: The accessibility analysis enabled the sitting of the centres to be evaluated for 2006, a comparison to be made with 2011 (with six new facilities having been set up since 2006 and new locations for the siting of these six new facilities to be proposed. Conclusions: This study has enabled the optimum territorial locations to be proposed for the six mental health centres created between 2006 and 2011 that would allow travel times to be reduced for the greatest numbers of people possible. It can be stated on the basis of this study that, if territorial criteria had been taken into account, 97,720 inhabitants would have seen their travel times to their nearest mental health centres reduced using the same resources.

    Sibley Lyn M

    2011-01-01

    Full Text Available Abstract Background Studies comparing the access to health care of rural and urban populations have been contradictory and inconclusive. These studies are complicated by the influence of other factor which have been shown to be related to access and utilization. This study assesses the equity of access to health care services across the rural-urban continuum in Canada before and after taking other determinants of access into account. Methods This is a cross-sectional study of the population of the 10 provinces of Canada using data from the Canadian Community Health Survey (CCHS 2.1. Five different measures of access and utilization are compared across the continuum of rural-urban. Known determinants of utilization are taken into account according to Andersen's Health Behaviour Model (HBM; location of residence at the levels of province, health region, and community is also controlled for. Results This study found that residents of small cities not adjacent to major centres, had the highest reported utilisation rates of influenza vaccines and family physician services, were most likely to have a regular medical doctor, and were most likely to report unmet need. Among the rural categories there was a gradient with the most rural being least likely to have had a flu shot, use specialist physicians services, or have a regular medical doctor. Residents of the most urban centres were more likely to report using specialist physician services. Many of these differences are diminished or eliminated once other factors are accounted for. After adjusting for other factors those living in the most urban areas were more likely to have seen a specialist physician. Those in rural communities had a lower odds of receiving a flu shot and having a regular medical doctor. People residing in the most urban and most rural communities were less likely to have a regular medical doctor. Those in any of the rural categories were less likely to report unmet need

    Full Text Available National and University Library established remote access to information sources in september 2004. The article describes implementation and development of the service. Library wanted to offer information sources to users wherever and whenever they would need them. First main evaluation criteria for software selection were integration with existing authentication system and second no need for intervention user side. The EZproxy software from Useful Utilities was chosen. Key step to implementation was establishing communication between software applications EZproxy and COBISS library automation system. Library needed to obtain licence agreements from publishers. Promotion campaign aimed to notify large number of users. Only users of National & University Library were able to use the service. Other users and libraries of Ljubljana University requested to authenticate by credentials of their library. Remote access service was developed further in order to enable authentication for other libraries. We needed to establish authentication and authorisation system and also upgrade and install the communication command procedure on different servers. The data about service usage are presented.

  14. Privacy-Aware Relevant Data Access with Semantically Enriched Search Queries for Untrusted Cloud Storage Services.

    Pervez, Zeeshan; Ahmad, Mahmood; Khattak, Asad Masood; Lee, Sungyoung; Chung, Tae Choong

    2016-01-01

    Privacy-aware search of outsourced data ensures relevant data access in the untrusted domain of a public cloud service provider. Subscriber of a public cloud storage service can determine the presence or absence of a particular keyword by submitting search query in the form of a trapdoor. However, these trapdoor-based search queries are limited in functionality and cannot be used to identify secure outsourced data which contains semantically equivalent information. In addition, trapdoor-based methodologies are confined to pre-defined trapdoors and prevent subscribers from searching outsourced data with arbitrarily defined search criteria. To solve the problem of relevant data access, we have proposed an index-based privacy-aware search methodology that ensures semantic retrieval of data from an untrusted domain. This method ensures oblivious execution of a search query and leverages authorized subscribers to model conjunctive search queries without relying on predefined trapdoors. A security analysis of our proposed methodology shows that, in a conspired attack, unauthorized subscribers and untrusted cloud service providers cannot deduce any information that can lead to the potential loss of data privacy. A computational time analysis on commodity hardware demonstrates that our proposed methodology requires moderate computational resources to model a privacy-aware search query and for its oblivious evaluation on a cloud service provider.

  15. A Data Capsule Framework For Web Services: Providing Flexible Data Access Control To Users

    Kannan, Jayanthkumar; Chun, Byung-Gon

    2010-01-01

    This paper introduces the notion of a secure data capsule, which refers to an encapsulation of sensitive user information (such as a credit card number) along with code that implements an interface suitable for the use of such information (such as charging for purchases) by a service (such as an online merchant). In our capsule framework, users provide their data in the form of such capsules to web services rather than raw data. Capsules can be deployed in a variety of ways, either on a trusted third party or the user's own computer or at the service itself, through the use of a variety of hardware or software modules, such as a virtual machine monitor or trusted platform module: the only requirement is that the deployment mechanism must ensure that the user's data is only accessed via the interface sanctioned by the user. The framework further allows an user to specify policies regarding which services or machines may host her capsule, what parties are allowed to access the interface, and with what parameter...

  16. Some Programs Should Not Run on Laptops - Providing Programmatic Access to Applications Via Web Services

    Gupta, V.; Gupta, N.; Gupta, S.; Field, E.; Maechling, P.

    2003-12-01

    hosted these Web Services as a part of the SCEC Community Modeling Environment (SCEC/CME) ITR Project (http://www.scec.org/cme). We have implemented Web Services for several of the reasons sited previously. For example, we implemented a FORTRAN-based Earthquake Rupture Forecast (ERF) as a Web Service for use by client computers that don't support a FORTRAN runtime environment. We implemented a Generic Mapping Tool (GMT) Web Service for use by systems that don't have local access to GMT. We implemented a Hazard Map Calculator Web Service to execute Hazard calculations that are too computationally intensive to run on a local system. We implemented a Coordinate Conversion Web Service to enforce a standard and consistent method for converting between UTM and Lat/Lon. Our experience developing these services indicates both strengths and weakness in current Web Service technology. Client programs that utilize Web Services typically need network access, a significant disadvantage at times. Programs with simple input and output parameters were the easiest to implement as Web Services, while programs with complex parameter-types required a significant amount of additional development. We also noted that Web services are very data-oriented, and adapting object-oriented software into the Web Service model proved problematic. Also, the Web Service approach of converting data types into XML format for network transmission has significant inefficiencies for some data sets.

  17. Distance, rurality and the need for care: access to health services in South West England

    Martin David

    2004-09-01

    Full Text Available Abstract Background This paper explores the geographical accessibility of health services in urban and rural areas of the South West of England, comparing two measures of geographical access and characterising the areas most remote from hospitals. Straight-line distance and drive-time to the nearest general practice (GP and acute hospital (DGH were calculated for postcodes and aggregated to 1991 Census wards. The correlation between the two measures was used to identify wards where straight-line distance was not an accurate predictor of drive-time. Wards over 25 km from a DGH were classified as 'remote', and characterised in terms of rurality, deprivation, age structure and health status of the population. Results The access measures were highly correlated (r2>0.93. The greatest differences were found in coastal and rural wards of the far South West. Median straight-line distance to GPs was 1 km (IQR = 0.6–2 km and to DGHs, 12 km (IQR = 5–19 km. Deprivation and rates of premature limiting long term illness were raised in areas most distant from hospitals, but there was no evidence of higher premature mortality rates. Half of the wards remote from a DGH were not classed as rural by the Office for National Statistics. Almost a quarter of households in the wards furthest from hospitals had no car, and the proportion of households with access to two or more cars fell in the most remote areas. Conclusion Drive-time is a more accurate measure of access for peripheral and rural areas. Geographical access to health services, especially GPs, is good, but remoteness affects both rural and urban areas: studies concentrating purely on rural areas may underestimate geographical barriers to accessing health care. A sizeable minority of households still had no car in 1991, and few had more than one car, particularly in areas very close to and very distant from hospitals. Better measures of geographical access, which integrate public and private transport

    Full Text Available Along with three years implementation of health reform in China, this study aimed at providing the up-to-date evidence about the accessibility of essential public health services (EPHS among adults with chronic diseases (CDs in both urban and rural areas, as well as determinants in access to EPHS.The data were collected from a cross-sectional survey conducted in 2013, which used a multistage stratified random sampling method to select 54 urban communities and 54 rural villages. Hypertension patients and diabetes patients were the target population who are the main beneficiaries of EPHS. Single factor analysis of influencing factors on difference access to EPHS was performed by Chi-Square analysis. Logistic regression analysis was used to determine the predictors of effective management and effective control.Patients with hypertension or diabetes were predominantly middle-aged or older persons and had a mean age of 65.26 year. People with CDs in China have a higher basic accessibility rate in EPHS with more than 90% of them having experience in receiving EPHS. And those who are willing to receive services from doctors have the most positive influence on effective management and control in blood pressure or blood glucose. But unsatisfied quality and equity of EPHS still exist in primary health system. 90% of participants could receive EPHS, but just 44% of them could control their diseases effectively. And participants from cities had the higher rates in effective management (urban: rural = 57%: 50.6% and effective control (urban: rural = 39.5%: 27.8%.People with CDs have a high level in geography and economic accessibility to EPHS, but the effectiveness of health management also needs to be improved, especially for those living in rural areas. Our study highlights the continuing need for improving ability to provide EPHS and the equality among regions. Meanwhile, strengthen health education and promotion for patients with CDs to improve their

    The Terrestrial Observation and Prediction System (TOPS) at NASA Ames Research Center's Ecological Forecasting Lab generates a suite of gridded data products in near real-time that are designed to enhance management decisions related to floods, droughts, forest fires, human health, as well as crop, range, and forest production. Derived from the synthesis of satellite imagery, ground observations, and specialized ecosystem models, our data products hold great potential for supporting research and practical applications across a wide range of disciplines. In order to provide enhanced access to our data and to promote multidisciplinary collaboration we implement standards-based web services. We serve TOPS data conforming to the Open-source Project for a Network Data Access Protocol (OPeNDAP) which allows subsetting and distribution of large HDF or NetCDF datasets, complete with standards-based metadata. Additionally, we implement a standard Web Map Service (WMS) for visualization of geospatial data. To further extend the use of our data to a wider audience we build upon these web services to develop browser-based visualization and analysis tools. We use Asynchronous Javascript and XML (AJAX) techniques to build interactive web applications leveraging our web services. For example, our WMS provides the map image tiles used in our mapping client. Users can click on the map to query TOPS datasets and regional summaries via OPeNDAP, producing time-series charts allowing temporal analysis of environmental trends and associated phenomena. We present the TOPS Data Gateway and its components, highlighting how the use of open protocols and standards provides improved data access for our clients and research partners, encouraging data interoperability and multidisciplinary collaboration.

  20. Applying the Earth System Grid Security System in a Heterogeneous Environment of Data Access Services

    Kershaw, Philip; Lawrence, Bryan; Lowe, Dominic; Norton, Peter; Pascoe, Stephen

    2010-05-01

    CEDA (Centre for Environmental Data Archival) based at STFC Rutherford Appleton Laboratory is host to the BADC (British Atmospheric Data Centre) and NEODC (NERC Earth Observation Data Centre) with data holdings of over half a Petabyte. In the coming months this figure is set to increase by over one Petabyte through the BADC's role as one of three data centres to host the CMIP5 (Coupled Model Intercomparison Project Phase 5) core archive of climate model data. Quite apart from the problem of managing the storage of such large volumes there is the challenge of collating the data together from the modelling centres around the world and enabling access to these data for the user community. An infrastructure to support this is being developed under the US Earth System Grid (ESG) and related projects bringing together participating organisations together in a federation. The ESG architecture defines Gateways, the web interfaces that enable users to access data and data serving applications organised into Data Nodes. The BADC has been working in collaboration with US Earth System Grid team and other partners to develop a security system to restrict access to data. This provides single sign-on via both OpenID and PKI based means and uses role based authorisation facilitated by SAML and OpenID based interfaces for attribute retrieval. This presentation will provide an overview of the access control architecture and look at how this has been implemented for CEDA. CEDA has developed an expertise in data access and information services over several years through a number of projects to develop and enhance these capabilities. Participation in CMIP5 comes at a time when a number of other software development activities are coming to fruition. New services are in the process of being deployed alongside services making up the system for ESG. The security system must apply access control across this heterogeneous environment of different data services and technologies. One strand

  1. The Copernicus Climate Change Service (C3S): Open Access to a Climate Data Store

    Thepaut, Jean-Noel; Dee, Dick

    2016-04-01

    In November 2014, The European Centre for Medium-range Weather Forecasts (ECMWF) signed an agreement with the European Commission to deliver two of the Copernicus Earth Observation Programme Services on the Commission's behalf. The ECMWF delivered services - the Copernicus Climate Change Service (C3S) and Atmosphere Monitoring Service (CAMS) - will bring a consistent standard to how we monitor and predict atmospheric conditions and climate change. They will maximise the potential of past, current and future earth observations - ground, ocean, airborne, satellite - and analyse these to monitor and predict atmospheric conditions and in the future, climate change. With the wealth of free and open data that the services provide, they will help business users to assess the impact of their business decisions and make informed choices, delivering a more energy efficient and climate aware economy. These sound investment decisions now will not only stimulate growth in the short term, but reduce the impact of climate change on the economy and society in the future. C3S is in its proof of concept phase and through its Climate Data Store will provide • global and regional climate data reanalyses; • multi-model seasonal forecasts; • customisable visual data to enable examination of wide range of scenarios and model the impact of changes; • access to all the underlying data, including climate data records from various satellite and in-situ observations. In addition, C3S will provide key indicators on climate change drivers (such as carbon dioxide) and impacts (such as reducing glaciers). The aim of these indicators will be to support European adaptation and mitigation policies in a number of economic sectors. At the heart of the Service is the provision of open access to a one stop shop (the Climate Data Store) of climate data and modelling, analysing more than 20 Essential Climate Variables to build a global picture of our past, present and future climate and developing

  2. The post-2015 delivery of universal and sustainable access to infrastructure services. Working Paper

    Doczi, Julian, Dorr, Tobias; Mason, Nathaniel; Scott, Andrew

    2013-06-15

    In this new working paper, the authors focus specifically on what would be necessary to achieve High Level Panel-style goals and targets for water, energy and transport, if these were to be eventually adopted by world leaders. In all three cases, much of the advocacy - and the proposed High Level Panel goals - have emphasized the need to strive for universal and sustainable access to at least basic levels of services from these sectors. Many of the proposals for post-2015 goals and targets appear ambitious, but what would it take to achieve them? This paper assesses what is needed to achieve goals for universal and sustainable access to infrastructure, specifically water, energy and transport. Using illustrative goals and targets, the paper reviews the development challenges in each sector, and what will be necessary to overcome the barriers to universal and sustainable access to water, energy and transport infrastructure services, in the areas of governance, finance, capacity development and environmental protection. The paper ends with general conclusions about infrastructure in the post-2015 development agenda.

    Full Text Available Abstract Background Inequity of accessibility to and utilization of reproductive health (RH services among youths is a global concern, especially in resource-limited areas. The level of inequity also varies by cultural and socio-economic contexts. To tailor RH services to the needs of youths, relevant solutions are required. This study aimed to assess baseline information on access to and utilization of RH services and unmet needs among youths living in resource-limited, suburban communities of Mandalay City, Myanmar. Methods A community-based, cross-sectional study was conducted in all resource-limited, suburban communities of Mandalay City, Myanmar. A total of 444 randomly selected youths aged between 15 and 24 years were interviewed for three main outcomes, namely accessibility to and utilization of RH services and youth's unmet needs for these services. Factors associated with these outcomes were determined using multivariate logistic regression. Results Although geographical accessibility was high (79.3%, financial accessibility was low (19.1% resulting in a low overall accessibility (34.5% to RH services. Two-thirds of youths used some kind of RH services at least once in the past. Levels of unmet needs for sexual RH information, family planning, maternal care and HIV testing were 62.6%, 31.9%, 38.7% and 56.2%, respectively. Youths living in the south or south-western suburbs, having a deceased parent, never being married or never exposed to mass media were less likely to access RH services. Being a young adult, current student, working as a waste recycler, having ever experienced a sexual relationship, ever being married, ever exposed to mass media, having a high knowledge of RH services and providers or a high level of accessibility to RH services significantly increased the likelihood of utilization of those services. In addition to youths’ socio-demographic characteristics, exposure to mass media, norm of peer exposure and knowledge

    Full Text Available Digital watermarking is well known as enabling technology to prove ownership on copyrighted material, detect originators of illegally made copies, monitor the usage of the copyrighted multimedia data and analyze the spread spectrum of the data over networks and servers. Research has shown that data hiding techniques can be applied successfully to other application areas like manipulations recognition. In this paper, we show our innovative approach for integrating watermark and cryptography based methods within a framework of new application scenarios spanning a wide range from dedicated and user specific services, “Try&Buy” mechanisms to general means for long-term customer relationships. The tremendous recent efforts to develop and deploy ubiquitous mobile communication possibilities are changing the demands but also possibilities for establishing new business and commerce relationships. Especially we motivate annotation watermarks and aspects of M-Commerce to show important scenarios for access control. Based on a description of the challenges of the application domain and our latest work we discuss, which methods can be used for establishing services in a fast convenient and secure way for conditional access services based on digital watermarking combined with cryptographic techniques. We introduce an example scenario for digital audio and an overview of steps in order to establish these concepts practically.

    2005-01-01

    Recent research works examine the potential employment of public-key cryptography schemes in e-health environments. In such systems, where a Public Key Infrastructure (PKI) is established beforehand, Attribute Certificates (ACs) and public key enabled protocols like TLS, can provide the appropriate mechanisms to effectively support authentication, authorization and confidentiality services. In other words, mutual trust and secure communications between all the stakeholders, namely physicians, patients and e-health service providers, can be successfully established and maintained. Furthermore, as the recently introduced mobile devices with access to computer-based patient record systems are expanding, the need of physicians and nurses to interact increasingly with such systems arises. Considering public key infrastructure requirements for mobile online health networks, this paper discusses the potential use of Attribute Certificates (ACs) in an anticipated trust model. Typical trust interactions among doctors, patients and e-health providers are presented, indicating that resourceful security mechanisms and trust control can be obtained and implemented. The application of attribute certificates to support medical mobile service provision along with the utilization of the de-facto TLS protocol to offer competent confidentiality and authorization services is also presented and evaluated through experimentation, using both the 802.11 WLAN and General Packet Radio Service (GPRS) networks.

    2013-11-01

    Virtual microscopy (VM) facilitates visualization and deployment of histopathological virtual slides (VS), a useful tool for education, research and diagnosis. In recent years, it has become popular, yet its use is still limited basically because of the very large sizes of VS, typically of the order of gigabytes. Such volume of data requires efficacious and efficient strategies to access the VS content. In an educative or research scenario, several users may require to access and interact with VS at the same time, so, due to large data size, a very expensive and powerful infrastructure is usually required. This article introduces a novel JPEG2000-based service oriented architecture for streaming and visualizing very large images under scalable strategies, which in addition need not require very specialized infrastructure. Results suggest that the proposed architecture enables transmission and simultaneous visualization of large images, while it is efficient using resources and offering users proper response times.

    Janelle Hippe

    2014-06-01

    Full Text Available Research indicates that people living in rural and remote areas of Canada face challenges to accessing health services. This article reports on a community-engaged research project conducted by investigators at Memorial University of Newfoundland in collaboration with the Rural Secretariat Regional Councils and Regional Partnership Planners for the Corner Brook–Rocky Harbour and Stephenville–Port aux Basques Rural Secretariat Regions of Newfoundland and Labrador. The aim of this research was to gather information on barriers to accessing health services, to identify solutions to health services’ access issues and to inform policy advice to government on enhancing access to health services. Data was collected through: (1 targeted distribution of a survey to communities throughout the region, and (2 informal ‘kitchen table’ discussions to discuss health services’ access issues. A total of 1049 surveys were collected and 10 kitchen table discussions were held. Overall, the main barriers to care listed in the survey included long wait times, services not available in the area and services not available at time required. Other barriers noted by survey respondents included transportation problems, financial concerns, no medical insurance coverage, distance to travel and weather conditions. Some respondents reported poorer access to maternal/child health and breast and cervical screening services and a lack of access to general practitioners, pharmacy services, dentists and nurse practitioners. Recommendations that emerged from this research included improving the recruitment of rural physicians, exploring the use of nurse practitioners, assisting individuals with travel costs,  developing specialist outreach services, increasing use of telehealth services and initiating additional rural and remote health research.

  12. Apollo: Giving application developers a single point of access to public health models using structured vocabularies and Web services

    Wagner, Michael M.; Levander, John D.; Brown, Shawn; Hogan, William R.; Millett, Nicholas; Hanna, Josh

    2013-01-01

    This paper describes the Apollo Web Services and Apollo-SV, its related ontology. The Apollo Web Services give an end-user application a single point of access to multiple epidemic simulators. An end user can specify an analytic problem—which we define as a configuration and a query of results—exactly once and submit it to multiple epidemic simulators. The end user represents the analytic problem using a standard syntax and vocabulary, not the native languages of the simulators. We have demonstrated the feasibility of this design by implementing a set of Apollo services that provide access to two epidemic simulators and two visualizer services. PMID:24551417

    The EarthScope Plate Boundary Observatory (PBO) at UNAVCO, Inc., part of the NSF-funded EarthScope project, is designed to study the three-dimensional strain field resulting from deformation across the active boundary zone between the Pacific and North American plates in the western United States. To meet these goals, PBO will install 880 continuous GPS stations, 103 borehole strainmeter stations, and five laser strainmeters, as well as manage data for 209 previously existing continuous GPS stations and one previously existing laser strainmeter. UNAVCO provides access to data products from these stations, as well as general information about the PBO project, via the PBO web site (http://pboweb.unavco.org). GPS and strainmeter data products can be found using a variety of access methods, incuding map searches, text searches, and station specific data retrieval. In addition, the PBO construction status is available via multiple mapping interfaces, including custom web based map widgets and Google Earth. Additional construction details can be accessed from PBO operational pages and station specific home pages. The current state of health for the PBO network is available with the statistical snap-shot, full map interfaces, tabular web based reports, and automatic data mining and alerts. UNAVCO is currently working to enhance the community access to this information by developing a web service framework for the discovery of data products, interfacing with operational engineers, and exposing data services to third party participants. In addition, UNAVCO, through the PBO project, provides advanced data management and monitoring systems for use by the community in operating geodetic networks in the United States and beyond. We will demonstrate these systems during the AGU meeting, and we welcome inquiries from the community at any time.

    Usman, Muneer

    2014-09-01

    Cognitive radio transceiver can opportunistically access the underutilized channels of primary systems for new wireless services. The secondary transmission may be interrupted by the primary user\\'s transmission. To facilitate the delay analysis of such secondary packet transmission, we study the resulting extended delivery time for a fixed-size secondary packet that includes both transmission time and waiting time. In particular we derive the exact distribution functions of extended delivery time of secondary transmission for both continuous sensing and periodic sensing cases. Selected numerical results are presented for illustrating the mathematical formulation.

    2007-01-01

    The aim of this paper is to determine the expectations that French-speaking disabled persons have for electronic administrative sites (utility). At the same time, it is a matter of identifying the difficulties of use that the manipulation of these E-services poses concretely for blind people (usability) and of evaluating the psychosocial impacts on the way of life of these people with specific needs. We show that the lack of numerical accessibility is likely to accentuate the social exclusion of which these people are victim by establishing a numerical glass ceiling.

  18. Spatial-Temporal dynamics of surface water flooding and consequences for emergency services accessibility

    Pattison, Ian; Green, Daniel; Yu, Dapeng; Bosher, Lee; Wilby, Rob; Yang, Lili; Ryley, Tim

    2016-04-01

    Urban areas are increasingly susceptible to surface water flooding, with more intense precipitation and intensification of land development. Flooding has both direct impacts i.e. locations inundated with water, and indirect impacts i.e. transport networks, utility e.g. electricity/water services etc. The direct areas flooded evolve in space through the event, and are predicted by standard inundation models. However, the wider indirect impacts and the spatial-temporal patterns are less constrained and it is these that are needed to manage the impacts in real-time. This paper focusses on the Category One responders of the Fire and Rescue and Ambulance Services in the City of Leicester, East Midlands, UK. Leicester is ranked 16th out of 4215 settlements at risk of surface water flooding in the UK based upon the population at risk (15,200 people) (DEFRA, 2009). The analysis undertaken involved overlaying the flood extent with the Integrated Transport Network (ITN) data within a GIS framework. Then a simple transport routing algorithm was used to predict the travel time from specific nodes representing ambulance or fire stations to different parts of the city. Flood magnitudes with 1:20, 1:100 and 1:1000 return periods have been investigated. Under a scenario of no flooding, 100% of the city is accessible by the six fire stations in the city. However, in the 1 in 20 year surface water flood event the peak inundation results in 66.5% being accessible in the 10 minute permitted time and 6% is totally inaccessible. This falls to 40% and 13% respectively for the 1 in 100 year event. Maps show the area of the city that are accessible by two or more stations within the permitted response time, which shows these areas are the most resilient to surface water flooding. However, it isn't just the peak water depths at every location which impacts accessibility within the city but the spatial-temporal patterns of the inundation. The areas within the 10 minute response time expand

  2. A framework for improving access and customer service times in health care: application and analysis at the UCLA Medical Center.

    Duda, Catherine; Rajaram, Kumar; Barz, Christiane; Rosenthal, J Thomas

    2013-01-01

    There has been an increasing emphasis on health care efficiency and costs and on improving quality in health care settings such as hospitals or clinics. However, there has not been sufficient work on methods of improving access and customer service times in health care settings. The study develops a framework for improving access and customer service time for health care settings. In the framework, the operational concept of the bottleneck is synthesized with queuing theory to improve access and reduce customer service times without reduction in clinical quality. The framework is applied at the Ronald Reagan UCLA Medical Center to determine the drivers for access and customer service times and then provides guidelines on how to improve these drivers. Validation using simulation techniques shows significant potential for reducing customer service times and increasing access at this institution. Finally, the study provides several practice implications that could be used to improve access and customer service times without reduction in clinical quality across a range of health care settings from large hospitals to small community clinics.

  3. Public service or commodity goods? Electricity reforms, access, and the politics of development in Tanzania

    Ghanadan, Rebecca Hansing

    Since the 1990s, power sector reforms have become paramount in energy policy, catalyzing a debate in Africa about market-based service provision and the effects of reforms on access. My research seeks to move beyond the conceptual divide by grounding attention not in abstract 'market forces' but rather in how development institutions shape energy services and actually practice policy on the ground. Using the case of Tanzania, a country known for having instituted some of the most extensive reforms and a 'success story' in Africa, I find that reforms are creating large burdens and barriers for access and use of services, including: increasing costs, enforcement pressures, and measures to impose 'market' discipline. However, I also find that many of the most significant outcomes are not found in direct 'market' changes, but rather how reforms are selective, partial, and shaped by the wider needs and claims of the institutions driving reforms, so that questions of how reforms are implemented, how they are measured, and who tells the story become as important as the policies themselves. Using a multiple-arenas framework, including (i) a household and community level study of urban energy conditions, (ii) a study of service and management conditions at the national electric utility, (iii) an examination of the international policy process, and (iv) a study of the history of electricity services across colonial, post-independence, and reform periods, I show that African energy reforms are a technical and political project connecting energy to international investments, donor aid programs, and elite interests within national governments. Energy reforms also involve fundamental service changes that are reorganizing how the costs and benefits of energy systems are distributed, allocated, and managed. The effects of reform extend beyond formal services to have wide-reaching repercussions within natural resources, and uneven social dynamics on the ground. These features point

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

    This study seeks to identify the formation of social support networks of people with physical disabilities, and how these networks can help facilitate access to health services and promote social inclusion. It is a cross-sectional study, with data collected via a form applied to physically disabled persons over eighteen years of age registered with the Family Health Teams of the municipal district of João Pessoa in the state of Paraíba. It was observed that the support networks of these individuals predominantly consist of family members (parents, siblings, children, spouses) and people outside the family (friends and neighbors). However, 50% of the interviewees declared that they could not count on any support from outside the family. It was observed that the support network contributes to access to the services and participation in social groups. However, reduced social inclusion was detected, due to locomotion difficulties, this being the main barrier to social interaction. Among those individuals who began to interact in society, the part played by social support was fundamental. PMID:25650611

  7. [The social value of teeth and access to dental health services].

    Fonseca, Luciara Leão Viana; Nehmy, Rosa Maria Quadros; Mota, Joaquim Antônio César

    2015-10-01

    Oral healthcare provided by the Unified Health System (SUS) faces the challenge of attending the epidemiological profile of Brazil's adult population. Qualitative research using semi-structured interviews was conducted to understand the experiences, expectations and perception of SUS users to services in Diamantina, State of Minas Gerais, and content analysis was used to assess the data. Discussion of the results was based on dialogue between the symbolic interactionism of Goffman and Bourdieu's concept of habitus. The results show that the users did not give importance to dental care during childhood and adolescence because care was unknown to them. There was no offer of treatment besides dental extraction. Today, they value teeth and suffer the embarrassment caused by rotten teeth. However, access to dental restoration via SUS is not possible. For their children, they perceive better access to information and care, but for specialized procedures there are barriers. They express resignation both in relation to the poor state of the teeth and the difficulties of access to dental care, which can be understood by the constant exclusion experienced by them in the past, shaping their actions in the present. It was concluded that oral health in SUS should incorporate the social value and the aesthetic dimension of teeth as a social right. PMID:26465855

  8. Access and preservation of digital research content: Linked open data services - A research library perspective

    Kraft, Angelina; Sens, Irina; Löwe, Peter; Dreyer, Britta

    2016-04-01

    Globally resolvable, persistent digital identifiers have become an essential tool to enable unambiguous links between published research results and their underlying digital resources. In addition, this unambiguous identification allows citation. In an ideal research world, any scientific content should be citable and the coherent content, as well as the citation itself, should be persistent. However, today's scientists do not just produce traditional research papers - they produce comprehensive digital collections of objects which, alongside digital texts, include digital resources such as research data, audiovisual media, digital lab journals, images, statistics and software code. Researchers start to look for services which allow management of these digital resources with minimum time investment. In light of this, we show how the German National Library of Science and Technology (TIB) develops supportive frameworks to accompany the life cycle of scientific knowledge generation and transfer. This includes technical infrastructures for • indexing, cataloguing, digital preservation, DOI names and licencing for text and digital objects (the TIB DOI registration, active since 2004) and • a digital repository for the deposition and provision of accessible, traceable and citeable research data (RADAR). One particular problem for the management of data originating from (collaborating) research infrastructures is their dynamic nature in terms of growth, access rights and quality. On a global scale, systems for access and preservation are in place for the big data domains (e.g. environmental sciences, space, climate). However, the stewardship for disciplines without a tradition of data sharing, including the fields of the so-called long tail, remains uncertain. The RADAR - Research Data Repository - project establishes a generic end-point data repository, which can be used in a collaborative way. RADAR enables clients to upload, edit, structure and describe their

  12. Improving Access to Mental Health Services for Racialized Immigrants, Refugees, and Non-Status People Living with HIV/AIDS.

    Chen, Y Y Brandon; Li, Alan Tai; Fung, Kenneth Po; Wong, Josephine Pui

    2015-05-01

    The demographic characteristics of people living with HIV/AIDS (PHAs) in Canada are increasingly diverse. Despite literature suggesting a potentially heightened mental health burden borne by racialized immigrant, refugee, and non-status PHAs (IRN-PHAs), researchers have hitherto paid insufficient attention to whether existing services adequately address this need and how services might be improved. Employing community-based research methodology involving PHAs from five ethnoracial groups in Toronto, Ontario, this study explored IRN-PHAs' mental health service-seeking behaviors, service utilization experiences, and suggestions for service improvements. Results showed that while most IRN-PHAs were proactive in improving their mental health, their attempts to obtain support were commonly undermined by service provider mistreatment, unavailability of appropriate services, and multiple access barriers. A three-pronged approach involving IRN-PHA empowerment, anti-stigma and cultural competence promotion, and greater service integration is proposed for improving IRN-PHAs' mental health service experience.

  13. Improving access to essential health care services: the case of Israel.

    van de Ven, Wynand P M M

    2016-01-01

    In a recent article in this journal Simon-Tuval, Horev and Kaplan argue that in order to improve the protection of consumers there might be a need to impose a threshold on the medical loss ratio (MLR) for voluntary health insurance (VHI) in Israel [1]. Their argument is that VHI in Israel covers several essential services that are not covered by the mandatory benefits package due to budget constraints, while there are market failures in the VHI market that justify regulation to assure consumer protection such as high accessibility to high quality coverage. In this commentary it will be argued that in addition to market failures there are also government failures. It is doubtful whether imposing a threshold on MLR is effective because of government failures. It can be even counter-productive. Therefore, alternative regulatory measures are discussed to promote the protection of the beneficiaries. If essential services covered by VHI are unaffordable for some low-income people, government can extend the current mandatory basic health insurance so that it covers all essential services. If there is a budget restriction, the amount of government funds could be increased, or the health plans could be allowed to request an additional flat rate premium, set by them and to be paid by the consumer directly to their health plan. Also, effective out-of-pocket payments could be introduced. Subsidies could be given to low-income people to compensate for their additional expenses under the mandatory health insurance. If these changes are adopted, then the government would no longer be held responsible for access to benefits outside the mandatory health insurance. Accordingly, all VHI could be sold on the normal free insurance market, just as other types of indemnity insurance. In addition, the Israeli health insurance and healthcare markets could be made more competitive by introducing procompetitive regulation. This would increase the efficiency and affordability of healthcare

  14. Experiences of homosexual patients’ access to primary health care services in Umlazi, KwaZulu-Natal

    Nokulunga H. Cele

    2015-07-01

    Full Text Available Background: Homosexual patients are affected by social factors in their environment, and as a result may not have easy access to existing health care services. Prejudice against homosexuality and homosexual patients remains a barrier to them seeking appropriate healthcare. The concern is that lesbians and gays might delay or avoid seeking health care when they need it because of past discrimination or perceived homophobia within the health care thereby putting their health at risk.Aim of the study: The aim of the study was to explore and describe the experiences of homosexual patients utilising primary health care (PHC services in Umlazi in the province ofKwaZulu-Natal (KZN.Method: A qualitative, exploratory, descriptive study was conducted which was contextual innature. Semi-structured interviews were conducted with 12 participants. The findings of this study were analysed using content analysis.Results: Two major themes emerged from the data analysis, namely, prejudice against homosexual patients by health care providers and other patients at the primary health care facilities, and, homophobic behaviour from primary health care personnel.Conclusion: Participants experienced prejudice and homophobic behaviour in the course of utilising PHC clinics in Umlazi, which created a barrier to their utilisation of health services located there. Nursing education institutions, in collaboration with the National Department of Health, should introduce homosexuality and anti-homophobia education programmes during the pre-service and in-service education period. Such programmes will help to familiarise health care providers with the health care needs of homosexual patients and may decrease homophobic attitudes.

  16. Challenges Women with Disability Face in Accessing and Using Maternal Healthcare Services in Ghana: A Qualitative Study

    Ganle, John Kuumuori; Otupiri, Easmon; Obeng, Bernard; Edusie, Anthony Kwaku; Ankomah, Augustine; Adanu, Richard

    2016-01-01

    Background While a number of studies have examined the factors affecting accessibility to and utilisation of healthcare services by persons with disability in general, there is little evidence about disabled women's access to maternal health services in low-income countries and few studies consult disabled women themselves to understand their experience of care and the challenges they face in accessing skilled maternal health services. The objective of this paper is to explore the challenges women with disabilities encounter in accessing and using institutional maternal healthcare services in Ghana. Methods and Findings A qualitative study was conducted in 27 rural and urban communities in the Bosomtwe and Central Gonja districts of Ghana with a total of 72 purposively sampled women with different physical, visual, and hearing impairments who were either lactating or pregnant at the time of this research. Semi-structured in-depth interviews were used to gather data. Attride-Stirling’s thematic network framework was used to analyse the data. Findings suggest that although women with disability do want to receive institutional maternal healthcare, their disability often made it difficult for such women to travel to access skilled care, as well as gain access to unfriendly physical health infrastructure. Other related access challenges include: healthcare providers’ insensitivity and lack of knowledge about the maternity care needs of women with disability, negative attitudes of service providers, the perception from able-bodied persons that women with disability should be asexual, and health information that lacks specificity in terms of addressing the special maternity care needs of women with disability. Conclusions Maternal healthcare services that are designed to address the needs of able-bodied women might lack the flexibility and responsiveness to meet the special maternity care needs of women with disability.

  18. GSL: An Open Source Framework for the Rapid Development of Data Archive Access Services

    McWhirter, J.; Boler, F. M.; Bock, Y.; Squibb, M. B.; Ratzesberger, L.

    2011-12-01

    The Geodetic Seamless Archive Center (GSAC) project is a NASA ROSES ACCESS funded effort with the goal to define and implement a web service API for uniform querying across multiple geodetic data repositories. The project information technology partners include two International GNSS Service (IGS) Data Centers, CDDIS and SOPAC, and a third global NSF and NASA-funded Data Center, UNAVCO. A science partner, the University of Nevada, Reno Geodetic Laboratory is utilizing the services and contributing new quality assessment products. Each of the participant data centers has its own internal database schema and various web-based access mechanisms to suit the needs of their individual user communities. The software engineering challenge that we faced was to unify these access mechanisms into a common web service API. To facilitate the development of the GSAC interfaces within these disparate repositories we have developed a Java-based open source middleware framework called the GSAC Service Layer (GSL). It was recognized early on in the project that much of the required functionality within each repository could be provided by a common software layer, thus achieving a substantial reduction in the development effort required by each partner institution. The GSL provides a range of common services for repository configuration, initialization, database management, web interface generation, and data model and metadata creation. Each repository implementation then simply focuses on the core task of responding to query requests and delivering to the GSL layer the internal results. The GSL layer is then responsible for encoding the results in the desired format. A fundamental challenge in developing a framework such as the GSL is balancing the trade-off between the agnosticism needed within the GSL so that it is applicable to a wide range of problem domains and the specific needs required for a particular repository implementations. The GSL addresses this challenge through an

    Background Migrants form a substantial proportion of the population affected by the human immunodeficiency virus (HIV) epidemic in Europe, yet HIV prevention for this population is hindered by poor understanding of access to care and of postmigration transmission dynamics. Objective We present the design and methods of the advancing Migrant Access to health Services in Europe (aMASE) study, the first European cross-cultural study focused on multiple migrant populations. It aims to identify the structural, cultural, and financial barriers to HIV prevention, diagnosis, and treatment and to determine the likely country of HIV acquisition in HIV-positive migrant populations. Methods We delivered 2 cross-sectional electronic surveys across 10 countries (Belgium, France, Germany, Greece, Italy, the Netherlands, Portugal, Spain, Switzerland, and United Kingdom). A clinic survey aimed to recruit up to 2000 HIV-positive patients from 57 HIV clinics in 9 countries. A unique study number linked anonymized questionnaire data to clinical records data (viral loads, CD4 cell counts, viral clades, etc). This questionnaire was developed by expert panel consensus and cognitively tested, and a pilot study was carried out in 2 countries. A Web-based community survey (n=1000) reached those living with HIV but not currently accessing HIV clinics, as well as HIV-negative migrants. It was developed in close collaboration with a community advisory group (CAG) made up of representatives from community organizations in 9 of the participating countries. The CAG played a key role in data collection by promoting the survey to higher-risk migrant groups (sub-Saharan Africans, Latin Americans, men who have sex with men, and people who inject drugs). The questionnaires have considerable content overlap, allowing for comparison. Questions cover ethnicity, migration, immigration status, HIV testing and treatment, health-seeking behavior, sexual risk, and drug use. The electronic questionnaires

  1. A GeoServices Infrastructure for Near-Real-Time Access to Suomi NPP Satellite Data

    Evans, J. D.; Valente, E. G.; Hao, W.; Chettri, S.

    2012-12-01

    The new Suomi National Polar-orbiting Partnership (NPP) satellite extends NASA's moderate-resolution, multispectral observations with a suite of powerful imagers and sounders to support a broad array of research and applications. However, NPP data products consist of a complex set of data and metadata files in highly specialized formats; which NPP's operational ground segment delivers to users only with several hours' delay. This severely limits their use in critical applications such as weather forecasting, emergency / disaster response, search and rescue, and other activities that require near-real-time access to satellite observations. Alternative approaches, based on distributed Direct Broadcast facilities, can reduce the delay in NPP data delivery from hours to minutes, and can make products more directly usable by practitioners in the field. To assess and fulfill this potential, we are developing a suite of software that couples Direct Broadcast data feeds with a streamlined, scalable processing chain and geospatial Web services, so as to permit many more time-sensitive applications to use NPP data. The resulting geoservices infrastructure links a variety of end-user tools and applications to NPP data from different sources, and to other rapidly-changing geospatial data. By using well-known, standard software interfaces (such as OGC Web Services or OPeNDAP), this infrastructure serves a variety of end-user analysis and visualization tools, giving them access into datasets of arbitrary size and resolution and allowing them to request and receive tailored products on demand. The standards-based approach may also streamline data sharing among independent satellite receiving facilities, thus helping them to interoperate in providing frequent, composite views of continent-scale or global regions. To enable others to build similar or derived systems, the service components we are developing (based in part on the Community Satellite Processing Package (CSPP) from

    include any alterations based on changes in practice patterns, service use, or cancer treatments. Various alternate scenarios were also developed to show how supply and demand might change under different assumptions. Conclusions ASCO, policy makers, and the public have major challenges ahead of them to forestall likely shortages in the capacity to meet future demand for oncology services. A multifaceted strategy will be needed to ensure that Americans have access to oncology services in 2020, as no single action will fill the likely gap between supply and demand. Among the options to consider are increasing the number of oncology fellowship positions, increasing use of nonphysician clinicians, increasing the role of primary care physicians in the care of patients in remission, and redesigning service delivery.

  3. Access and acceptability of community-based services for older Greek migrants in Australia: user and provider perspectives.

    Hurley, Catherine; Panagiotopoulos, Georgia; Tsianikas, Michael; Newman, Lareen; Walker, Ruth

    2013-03-01

    In most developed nations, ageing migrants represent a growing proportion of the older population. Policies that emphasise care in the community depend on older migrants having access to formal services along with informal support, yet little is known about how older migrants experience community-based formal services. By examining the views of both Greek elders in Australia and those of formal service providers, this research fills an important gap in the literature around access to and acceptability of formal community-based services for older migrants. A research team including two Greek background researchers used existing social groups and a snowball sampling method to conduct face-to-face interviews and focus groups with seventy older Greeks in Adelaide, Australia. In addition, 22 community-based service providers were interviewed over the telephone. Results from users and providers showed that while many older Greeks experience service access issues, they also relied heavily on family for support and assistance at home. Reliance on family was both in preference to formal services or where formal services were used, to locate, negotiate and monitor such services. Common barriers identified by both groups included cost, transport and availability, but additional challenges were posed by language, literacy and cultural attitudes. Demographic changes including greater employment mobility and female workforce participation among adult children will have implications for both formal and informal care providers. Formal service providers need to ensure that services are promoted and delivered to take account of the important role of family in informal support while also addressing the access challenges posed by language and literacy. Research conducted by researchers from the same cultural background in the respondent's native language can further advance knowledge in this area. PMID:23009742

  4. Data Access Tools And Services At The Goddard Distributed Active Archive Center (GDAAC)

    Pham, L. B.; Eng, E.; Sweatman, P.

    2003-12-01

    As one of the largest providers of Earth Science data from the Earth Observing System, GDAAC provides the latest data from the Moderate Resolution Imaging Spectroradiometer (MODIS), Atmospheric Infrared Sounder (AIRS), Solar Radiation and Climate Experiment (SORCE) data products via GDAAC's data pool (50TB of disk cache). In order to make this huge volume of data more accessible to the public and science communities, the GDAAC offers multiple data access tools and services: Open Source Project for Network Data Access Protocol (OPeNDAP), Grid Analysis and Display System (GrADS/DODS) (GDS), Live Access Server (LAS), OpenGIS Web Map Server (WMS) and Near Archive Data Mining (NADM). The objective is to assist users in retrieving electronically a smaller, usable portion of data for further analysis. The OPeNDAP server, formerly known as the Distributed Oceanographic Data System (DODS), allows the user to retrieve data without worrying about the data format. OPeNDAP is capable of server-side subsetting of HDF, HDF-EOS, netCDF, JGOFS, ASCII, DSP, FITS and binary data formats. The GrADS/DODS server is capable of serving the same data formats as OPeNDAP. GDS has an additional feature of server-side analysis. Users can analyze the data on the server there by decreasing the computational load on their client's system. The LAS is a flexible server that allows user to graphically visualize data on the fly, to request different file formats and to compare variables from distributed locations. Users of LAS have options to use other available graphics viewers such as IDL, Matlab or GrADS. WMS is based on the OPeNDAP for serving geospatial information. WMS supports OpenGIS protocol to provide data in GIS-friendly formats for analysis and visualization. NADM is another access to the GDAAC's data pool. NADM gives users the capability to use a browser to upload their C, FORTRAN or IDL algorithms, test the algorithms, and mine data in the data pool. With NADM, the GDAAC provides an

    2013-12-01

    The wealth of data from geodetic observing systems, especially the Plate Boundary Observatory (PBO), presents major data management challenges. The challenges are driven by ingenious new uses of Global Positioning System (GPS) data, demands for higher-rate, lower latency data, the need for continued access and long term preservation of archival data, the expansion of data users into other science, engineering and commercial arenas, and the growth of enhanced products that expand the utility of the data. To meet these challenges, UNAVCO has established a comprehensive suite of data services encompassing sensor network data operations, data product generation (through the activities of partners at Massachusetts Institute of Technology, Central Washington University, New Mexico Institute of Mining and Technology, and the University of California, San Diego - UCSD), data management, access and archiving, and advanced cyberinfrastructure. PBO sensor systems include 1,100 continuously operating GPS stations, 79 borehole geophysical sites (with a combination of strainmeters, tiltmeters, seismometers, pore pressure gauges, and meteorological sensors), and 6 long baseline strainmeters. Imaging data acquired for EarthScope include large volumes of satellite synthetic aperture radar (SAR) and airborne LiDAR data. Core data products such as daily GPS position time series and derived crustal motion velocities have been augmented with real-time data streams and positions calculated every second from 367 PBO stations. Higher rate (5 Hz) data files are available for applications such as GPS seismology. Efforts are underway with UCSD to integrate GPS and accelerometers at a subset of PBO sites to increase the reliability and capability of the observations. These observations have utility for research and hazards mitigation. Ingenious methods of GPS data analysis, developed by the University of Colorado and the University Corporation for Atmospheric Research, measure snow depth

  6. A Model for Remote Access and Protection of Smartphones using Short Message Service

    Kuppusamy, K S; Aghila, G; 10.5121/ijcseit.2012.2109

    2012-01-01

    The smartphone usage among people is increasing rapidly. With the phenomenal growth of smartphone use, smartphone theft is also increasing. This paper proposes a model to secure smartphones from theft as well as provides options to access a smartphone through other smartphone or a normal mobile via Short Message Service. This model provides option to track and secure the mobile by locking it. It also provides facilities to receive the incoming call and sms information to the remotely connected device and enables the remote user to control the mobile through SMS. The proposed model is validated by the prototype implementation in Android platform. Various tests are conducted in the implementation and the results are discussed.

  7. Comparison of Traditional and Open-Access Appointment Scheduling for Exponentially Distributed Service Time.

    Yan, Chongjun; Tang, Jiafu; Jiang, Bowen; Fung, Richard Y K

    2015-01-01

    This paper compares the performance measures of traditional appointment scheduling (AS) with those of an open-access appointment scheduling (OA-AS) system with exponentially distributed service time. A queueing model is formulated for the traditional AS system with no-show probability. The OA-AS models assume that all patients who call before the session begins will show up for the appointment on time. Two types of OA-AS systems are considered: with a same-session policy and with a same-or-next-session policy. Numerical results indicate that the superiority of OA-AS systems is not as obvious as those under deterministic scenarios. The same-session system has a threshold of relative waiting cost, after which the traditional system always has higher total costs, and the same-or-next-session system is always preferable, except when the no-show probability or the weight of patients' waiting is low. It is concluded that open-access policies can be viewed as alternative approaches to mitigate the negative effects of no-show patients. PMID:26753439

    2012-08-01

    Full Text Available Abstract Background Despite the emergence of mental health problems during adolescence and early adulthood, many young people encounter difficulties accessing appropriate services. In response to this gap, the Australian Government recently established new enhanced primary care services (headspace that target young people with emerging mental health problems. In this study, we examine the experience of young people with depression accessing one of these services, with a focus on understanding how they access the service and the difficulties they encounter in the process. Method Individual, in-depth, audio-recorded interviews were used to collect data. Twenty-six young people with depression were recruited from a headspace site in Melbourne, Australia. Interpretative phenomenological analysis was used to analyse the data. Results Four overlapping themes were identified in the data. First, school counsellors as access mediators, highlights the prominent role school counsellors have in facilitating student access to the service. Second, location as an access facilitator and inhibitor. Although the service is accessible by public transport, it is less so to those who do not live near public transport. Third, encountering barriers accessing the service initially. Two main service access barriers were experienced: unfamiliarity with the service, and delays in obtaining initial appointments for ongoing therapy. Finally, the service’s funding model acts as an access facilitator and barrier. While the model provides a low or no cost services initially, it limits the number of funded sessions, and this can be problematic. Conclusions Young people have contrasting experiences accessing the service. School counsellors have an influential role in facilitating access, and its close proximity to public transport enhances access. The service needs to become more prominent in young people’s consciousness, while the appointment system would benefit from

  9. Consumers’ experiences of back pain in rural Western Australia: access to information and services, and self-management behaviours

    2012-10-01

    Full Text Available Abstract Background Coordinated, interdisciplinary services, supported by self-management underpin effective management for chronic low back pain (CLBP. However, a combination of system, provider and consumer-based barriers exist which limit the implementation of such models into practice, particularly in rural areas where unique access issues exist. In order to improve health service delivery for consumers with CLBP, policymakers and service providers require a more in depth understanding of these issues. The objective of this qualitative study was to explore barriers experienced by consumers in rural settings in Western Australia (WA to accessing information and services and implementing effective self-management behaviours for CLBP. Methods Fourteen consumers with a history of CLBP from three rural sites in WA participated. Maximum variation sampling was employed to ensure a range of experiences were captured. An interviewer, blinded to quantitative pain history data, conducted semi-structured telephone interviews using a standardised schedule to explore individuals’ access to information and services for CLBP, and self-management behaviours. Interviews were digitally recorded and transcribed verbatim. Inductive analysis techniques were used to derive and refine key themes. Results Five key themes were identified that affected individuals’ experiences of managing CLBP in a rural setting, including: 1 poor access to information and services in rural settings; 2 inadequate knowledge and skills among local practitioners; 3 feelings of isolation and frustration; 4 psychological burden associated with CLBP; and 5 competing lifestyle demands hindering effective self-management for CLBP. Conclusions Consumers in rural WA experienced difficulties in knowing where to access relevant information for CLBP and expressed frustration with the lack of service delivery options to access interdisciplinary and specialist services for CLBP.

    2015-07-01

    Full Text Available The target of the Open Geospatial Consortium (OGC is interoperability of geographic information, which means creating opportunities to access geodata in a consistent, standardized way. In the domain of sensor data, the target will be picked up within the OGC Sensor Web Enablement Initiative and especially reached through the Sensor Observation Service (SOS standard. This one defines a service for a standardized access to time series data and is usually used for in situ sensors (like discharge gauges and climate stations. Although the standard considers raster data, no implementation of the standard for raster data exists presently. In this paper an OGC-compliant Sensor Observation Service for a standardized access to raster data is described. A data model was developed that enables effective storage of the raster data with the corresponding metadata in a database, reading this data in an efficient way, and encoding it with result formats that the SOS-standard provides.

  11. Open access to information bridges science and development in Amazonia: lessons of the SIAMAZONIA service

    Access to and availability of accurate information has often been stated to play an important role in sustainable environmental management. There is a growing trend of setting up internet-based information services to support the availability of relevant information. The current initiatives that aim to facilitate such information sharing through the web are still, however, often premature and unable to ensure constant flow of data from producers to users. We examine these common challenges by using as an example a network-based facility of biodiversity and environmental information about the Peruvian Amazon region called SIAMAZONIA. Launched in 2001, the service includes data provided by 13 different nodes. The experiences of this initiative have been both encouraging and confusing. A good professional level has been reached, but participation by large information holders is impeded. Participation is obviously considered an additional task rather than an attractive option for enhanced performance at the individual or institutional levels. This dilemma reflects a genuine problem in the modern scientific community, which still lacks agreed ways to reward those who share their data and results through the web. If these problems are solved, internet-based information sharing may become a vital resource for environmental management in Amazonia and also elsewhere

  12. Q-SOS—A Sensor Observation Service for Accessing Quality Descriptions of Environmental Data

    Anusuriya Devaraju

    2015-08-01

    Full Text Available The worldwide Sensor Web comprises observation data from diverse sources. Each data provider may process and assess datasets differently before making them available online. This information is often invisible to end users. Therefore, publishing observation data with quality descriptions is vital as it helps users to assess the suitability of data for their applications. It is also important to capture contextual information concerning data quality such as provenance to trace back incorrect data to its origins. In the Open Geospatial Consortium (OGC’s Sensor Web Enablement (SWE framework, there is no sufficiently and practically applicable approach how these aspects can be systematically represented and made accessible. This paper presents Q-SOS—an extension of the OGC’s Sensor Observation Service (SOS that supports retrieval of observation data together with quality descriptions. These descriptions are represented in an observation data model covering various aspects of data quality assessment. The service and the data model have been developed based on open standards and open source tools, and are productively being used to share observation data from the TERENO observatory infrastructure. We discuss the advantages of deploying the presented solutions from data provider and consumer viewpoints. Enhancements applied to the related open-source developments are also introduced.

  13. A Spectrum Access Based on Quality of Service (QoS) in Cognitive Radio Networks.

    Zhai, Linbo; Wang, Hua; Gao, Chuangen

    2016-01-01

    The quality of service (QoS) is important issue for cognitive radio networks. In the cognitive radio system, the licensed users, also called primary users (PUs), are authorized to utilize the wireless spectrum, while unlicensed users, also called secondary users (SUs), are not authorized to use the wireless spectrum. SUs access the wireless spectrum opportunistically when the spectrum is idle. While SUs use an idle channel, the instance that PUs come back makes SUs terminate their communications and leave the current channel. Therefore, quality of service (QoS) is difficult to be ensured for SUs. In this paper, we first propose an analysis model to obtain QoS for cognitive radio networks such as blocking probability, completed traffic and termination probability of SUs. When the primary users use the channels frequently, QoS of SUs is difficult to be ensured, especially the termination probability. Then, we propose a channel reservation scheme to improve QoS of SUs. The scheme makes the terminated SUs move to the reserved channels and keep on communications. Simulation results show that our scheme can improve QoS of SUs especially the termination probability with a little cost of blocking probability in dynamic environment. PMID:27171196

    Full Text Available Abstract Background HIV counseling and testing is an important intervention in the prevention, control and management of the human immunodeficiency virus (HIV. Counseling and testing can be an entry point for prevention, care and support. Knowledge of the quality of services and motivations for testing by individuals is important for effective understanding of the testing environment. Methods A cross sectional explorative study of clients accessing HIV voluntary counseling and testing (VCT and counselors was conducted in 6 government health centers in Blantyre City, Malawi. We aimed to assess the availability of critical clinic supplies and identify the motivations of clients seeking counseling and testing services. We also aimed to identify the health professional cadres that were providing VCT in Blantyre city. Results 102 VCT clients and 26 VCT counselors were interviewed. Among the VCT clients, 74% were Conclusion HIV counseling and testing facilities were available in Blantyre city in all the six public health facilities assessed. The majority of counseling and testing clients were motivated by perceptions of being at risk of HIV infection. In a country with 12% of individuals 15 to 49 years infected, there is need to encourage testing among population groups that may not perceive themselves to be at risk of infection.

  15. A Time-constrained Network Voronoi Construction and Accessibility Analysis in Location-based Service Technology

    Yu, W.; Ai, T.

    2014-11-01

    Accessibility analysis usually requires special models of spatial location analysis based on some geometric constructions, such as Voronoi diagram (abbreviated to VD). There are many achievements in classic Voronoi model research, however suffering from the following limitations for location-based services (LBS) applications. (1) It is difficult to objectively reflect the actual service areas of facilities by using traditional planar VDs, because human activities in LBS are usually constrained only to the network portion of the planar space. (2) Although some researchers have adopted network distance to construct VDs, their approaches are used in a static environment, where unrealistic measures of shortest path distance based on assumptions about constant travel speeds through the network were often used. (3) Due to the computational complexity of the shortest-path distance calculating, previous researches tend to be very time consuming, especially for large datasets and if multiple runs are required. To solve the above problems, a novel algorithm is developed in this paper. We apply network-based quadrat system and 1-D sequential expansion to find the corresponding subnetwork for each focus. The idea is inspired by the natural phenomenon that water flow extends along certain linear channels until meets others or arrives at the end of route. In order to accommodate the changes in traffic conditions, the length of network-quadrat is set upon the traffic condition of the corresponding street. The method has the advantage over Dijkstra's algorithm in that the time cost is avoided, and replaced with a linear time operation.

  19. Illness costs to households are a key barrier to access diagnostic and treatment services for tuberculosis in Tajikistan

    Abdualimova Hanifa

    2010-12-01

    Full Text Available Abstract Background Tuberculosis (TB control is based on early detection and complete treatment of infectious cases. Consequently, it is important that TB suspects and patients can readily access medical care. This qualitative study investigated determinants of access to DOTS services as identified by patients, health providers and community members in four districts in Tajikistan. Findings Focus group discussions were conducted in order to investigate access to TB services. A conceptual framework for access to care guided the analysis. Thirteen focus group discussions involving a total of 97 informants were conducted. Content analysis of discussions and a rating to quantify the relative importance of discussed factors were carried out. The conceptual framework identifies five main components of access to which factors can be assigned: availability, adequacy, acceptability, accessibility and affordability. Financial factors were considered the most important determinants of access to diagnosis and treatment of tuberculosis. Expenditure for drugs and consultations, for transport, and for special foods as well as lost income were identified as major barriers to treatment. Stigma, doubts about curability and low perceived quality of care were not seen to be significant determinants of access to care for tuberculosis. Community members were well aware of symptoms of tuberculosis and of medical services. These findings were consistent between different respondent groups (community members, patients and providers. They were also highly consistent between the open discussion and the confidential rating. Conclusions Illness-costs to households were identified as the main barrier to tuberculosis diagnosis and treatment. To improve access and ultimately adherence to tuberculosis treatment, effective mitigation strategies, e.g. changes in case management, food contributions or financial stimuli, need to be explored and implemented.

  20. Using Public-Private Partnerships to Mitigate Disparities in Access to Genetic Services: Lessons from Wisconsin

    Senier, Laura; Kearney, Matthew; Orne, Jason

    2016-01-01

    Purpose This mixed-methods study reports on an outreach clinics program designed to deliver genetic services to medically underserved communities in Wisconsin. Methodology We show the geographic distribution, funding patterns, and utilization trends for outreach clinics over a 20-year period. Interviews with program planners and outreach clinic staff show how external and internal constraints limited the program’s capacity. We compare clinic operations to the conceptual models guiding program design. Findings Our findings show that state health officials had to scale back financial support for outreach clinic activities while healthcare providers faced increasing pressure from administrators to reduce investments in charity care. These external and internal constraints led to a decline in the overall number of patients served. We also find that redistribution of clinics to the Milwaukee area increased utilization among Hispanics but not among African-Americans. Our interviews suggest that these patterns may be a function of shortcomings embedded in the planning models. Implications Planning models have three shortcomings. First, they do not identify the mitigation of health disparities as a specific goal. Second, they fail to acknowledge that partners face escalating profit-seeking mandates that may limit their capacity to provide charity services. Finally, they underemphasize the importance of seeking trusted partners, especially in working with communities that have been historically marginalized. Contribution There has been little discussion about equitably leveraging genetic advances that improve healthcare quality and efficacy. The role of State Health Agencies in mitigating disparities in access to genetic services has been largely ignored in the sociological literature.

  1. Access to Interpreter Services at U.S. Dental School Clinics.

    Simon, Lisa; Hum, Lauren; Nalliah, Romesh

    2016-01-01

    The number of Americans with limited English proficiency (LEP) is growing, and legal protections mandate that LEP individuals have equal access to health care services. The aim of this study was to determine the availability of interpretation services in U.S. dental school clinics and the kinds of instruction dental students are given regarding treatment of LEP patients. A survey was distributed to the academic deans of all U.S. dental schools; 35 completed the survey for a response rate of 58%. Respondents were asked to report on the number of LEP patients treated in their student clinics, the resources available to students working with LEP patients, and the extent of instruction offered. Descriptive statistics were calculated. The results indicated that the proportion of LEP patients treated at U.S. dental schools was perceived to be higher than that of the general population. The availability of interpreter services and the extent of student education about LEP individuals varied widely. Among the responding schools, the most common language spoken by LEP patients was Spanish, followed by Chinese (Mandarin and Cantonese) and Russian. Most of the responding dental schools reported offering fewer than two hours of instruction to their predoctoral students on treating LEP patients. Although almost 90% of the respondents indicated believing LEP patients received care equal in quality to that of non-LEP patients in their clinics, only 61.9% indicated that their students were adequately prepared to manage LEP patients following graduation. These findings suggest that dental schools should consider curricular innovations that will prepare students to work with LEP populations and improve the ability of LEP patients to receive care in the teaching clinic setting.

    2013-07-01

    Video on demand is a very attractive service used for entertainment, education, and other purposes. The design of passive optical networking+Ethernet over coaxial cable accessing and a home gateway system is proposed. The network integrates the passive optical networking and Ethernet over coaxial cable to provide high dedicated bandwidth for the metropolitan video-on-demand services. Using digital video broadcasting, IP television protocol, unicasting, and broadcasting mechanisms maximizes the system throughput. The home gateway finishes radio frequency signal receiving and provides three kinds of interfaces for high-definition video, voice, and data, which achieves triple-play and wire/wireless access synchronously.

    2006-06-15

    From the 13th to the 15th March 2006, the ENABLE team together with UNDP facilitated a three day consultative workshop hosted by the East African Community. The principal objective of this workshop was to facilitate the design of a regional energy access workplan and accompanying investment programmes to support the achievement of the millennium development goals. The workshop brought together almost 50 stakeholders from the East African region, representing various sectors (health, education, water, agriculture, environment, finance, etc.), organisations (public, private and NGOs) and donors, with the objective to identify and recommend actions that need to be undertaken in East Africa at regional, national and local levels in order to achieve the EAC Regional Energy Access Scale-up targets endorsed by the Ministers of Energy of Kenya, Tanzania and Uganda in August 2005. In order to generate new and substantive information during the three days, a highly interactive and participatory approach was used, where participants worked intensively in small groups with a set of questions which examined the issues and actions needed to achieve the four EAC Regional Energy Access Scale-up targets, as listed below: Target 1: Enable the use of modern fuels for 50% of those who at present use traditional biomass for cooking. Support efforts to develop and adopt the use of improved cook stoves, means to reduce indoor air pollution, and measures to increase sustainable biomass production. Target 2: Access to reliable modern energy services for all urban and peri-urban poor. Target 3: Electricity for services such as lighting, refrigeration, information and communication technology, and water treatment and supply for schools, clinics, hospitals and community centres. Target 4: Access to mechanical power within the community for all communities for productive uses. The main output from the workshop was a set of interventions for each of the energy access scale-up targets

    The EC policy for research in the new millennium supports the development of european-scale research infrastructures. In this perspective, the existing research infrastructures are going to be integrated with the objective to increase their accessibility and to enhance the usability of their multidisciplinary data. Building up integrating Earth Sciences infrastructures in Europe is the mission of the Implementation Phase (IP) of the European Plate Observing System (EPOS) project (2015-2019). The integration of european multiscale laboratories - analytical, experimental petrology and volcanology, magnetic and analogue laboratories - plays a key role in this context and represents a specific task of EPOS IP. In the frame of the WP16 of EPOS IP working package 16, European geosciences multiscale laboratories aims to be linked, merging local infrastructures into a coherent and collaborative network. In particular, the EPOS IP WP16-task 4 "Data services" aims at standardize data and data products, already existing and newly produced by the participating laboratories, and made them available through a new digital platform. The following data and repositories have been selected for the purpose: 1) analytical and properties data a) on volcanic ash from explosive eruptions, of interest to the aviation industry, meteorological and government institutes, b) on magmas in the context of eruption and lava flow hazard evaluation, and c) on rock systems of key importance in mineral exploration and mining operations; 2) experimental data describing: a) rock and fault properties of importance for modelling and forecasting natural and induced subsidence, seismicity and associated hazards, b) rock and fault properties relevant for modelling the containment capacity of rock systems for CO2, energy sources and wastes, c) crustal and upper mantle rheology as needed for modelling sedimentary basin formation and crustal stress distributions, d) the composition, porosity, permeability, and

    2016-07-01

    The prosperity of e-health is boosted by fast development of medical devices with wireless communications capability such as wearable devices, tiny sensors, monitoring equipments, etc., which are randomly distributed in clinic environments. The drastically-increasing population of such devices imposes new challenges on the limited wireless resources. To relieve this problem, key knowledge needs to be extracted from massive connection attempts dispersed in the air towards efficient access control. In this paper, a hybrid periodic-random massive access (HPRMA) scheme for wireless clinical networks employing ultra-narrow band (UNB) techniques is proposed. In particular, the proposed scheme towards accommodating a large population of devices include the following new features. On one hand, it can dynamically adjust the resource allocated for coexisting periodic and random services based on the traffic load learned from signal collision status. On the other hand, the resource allocation within periodic services is thoroughly designed to simultaneously align with the timing requests of differentiated services. Abundant simulation results are also presented to demonstrate the superiority of the proposed HPRMA scheme over baseline schemes including time-division multiple access (TDMA) and random access approach, in terms of channel utilization efficiency, packet drop ratio, etc., for the support of massive devices' services.

    2013-10-01

    Full Text Available Bolivian immigrants in Brazil experience serious social problems: precarious work conditions, lack of documents and insufficient access to health services. The study aimed to investigate inequalities in living conditions and access to health services among Bolivian immigrants living in the central area of São Paulo, Brazil, using a cross-sectional design and semi-structured interviews with 183 adults. According to the data, the immigrants tend to remain in Brazil, thus resulting in an aging process in the group. Per capita income increases the longer the immigrants stay in the country. The majority have secondary schooling. Work status does not vary according to time since arrival in Brazil. The immigrants work and live in garment sweatshops and speak their original languages. Social networks are based on ties with family and friends. Access to health services shows increasing inclusion in primary care. The authors conclude that the immigrants' social exclusion is decreasing due to greater access to documentation, work (although precarious, and the supply of health services from the public primary care system.

  13. Accessibility to health services in the prison population in Colombia: a public health challenge

    Luz Mery Mejía O

    2010-08-01

    Full Text Available This article is the result of a product of a study elaborated with the aim of systematizing the available information related to the accessibility to the health services of the prison population in the penitentiary centers. To this end, we reviewed the literature and systematic collection of the academic available material in the principal university libraries in the city of Medellin, scientific databases and the web pages of national and international organizations that have dealt with this topic. The information was systematized considering some historical references to prisons and health, the record of experiences in some countries and the current regulations for health care in the prison population in the Colombian case. We conclude that although significant progress has been made to ensure health care for the prison population, in the prison there are still obstacles and limitations that infringe the right to health of this population. Likewise, it is evidenced that it has not been considered a public health problem in the country, which it is considered a challenge to incorporate it as such.

  14. Enabling Access to Welfare Services - the Place of Social Solidarity and Dialogue

    2007-08-01

    Full Text Available The welfare state in the UK presents immigrant communities with a set of institutions, which are potentially new and unknown. What is the best way to ensure that the questions of access to the welfare institutions are best managed? Trusting, understanding and feeling solidarity with the welfare state will obviously help with this problem. In order to shed light on this phenomenon, this paper presents a qualitative exploratory study dealing with elements of solidarity as perceived by members of the South Asian Community in the UK. Six indepth interviews with South Asian first generation immigrants who had never experienced mental health problems were conducted. They were asked questions about who their support networks would be in the event of them experiencing mental health problems. The thematic analysis of the interviews suggests that the respondents believed that solidarity and support ties are found to be present in families, within the south Asian community and also with welfare institutions. It is concluded that there although things are far from perfect, assimilation and integration based on dialogue is an observable positive aspect of mental health service provision in the UK.

  15. The impact of health service variables on healthcare access in a low resourced urban setting in the Western Cape, South Africa

    Elsje Scheffler

    2015-02-01

    Full Text Available Background: Health care access is complex and multi-faceted and, as a basic right, equitable access and services should be available to all user groups.Objectives: The aim of this article is to explore how service delivery impacts on access to healthcare for vulnerable groups in an urban primary health care setting in South Africa.Methods: A descriptive qualitative study design was used. Data were collected through semi-structured interviews with purposively sampled participants and analysed through thematic content analysis.Results: Service delivery factors are presented against five dimensions of access according to the ACCESS Framework. From a supplier perspective, the organisation of care in the study setting resulted in available, accessible, affordable and adequate services as measured against the DistrictHealth System policies and guidelines. However, service providers experienced significant barriers in provision of services, which impacted on the quality of care, resulting in poor client and provider satisfaction and ultimately compromising acceptability of service delivery. Although users found services to be accessible, the organisation of services presented them with challenges in the domains of availability, affordability and adequacy, resulting in unmet needs, low levels of satisfaction and loss of trust. These challenges fuelled perceptions of unacceptable services.Conclusion: Well developed systems and organisation of services can create accessible, affordable and available primary healthcare services, but do not automatically translate into adequate and acceptable services. Focussing attention on how services are delivered might restore the balance between supply (services and demand (user needs and promote universal and equitable access.

  16. Changes in perceptions of quality of, and access to, services among clients of a fractional franchise network in Nepal.

    Agha, Sohail; Gage, Anastasia; Balal, Asma

    2007-05-01

    With declining levels of international donor funding for financing reproductive health programmes, developing country governments and international donors are looking towards private sector strategies to expand the supply of quality reproductive health services. One of the challenges of a health franchise is to improve the quality of services provided by independent private practitioners. Private providers are more likely to abide by the quality standards set by a franchiser if they see a financial benefit resulting from franchise participation. This study was conducted to measure whether (a) there were improvements in perceived quality of care and perceived access to health facilities once these facilities became part of a franchise and (b) improvements in perceived quality and perceived access were associated with increased client loyalty to franchised clinics. Franchisees were given basic reproductive health training for seven days and services marketing training for two days. Exit interviews were conducted with male and female clients at health facilities. A pre-test measurement was taken in April 2001, prior to the start of project activities. A post-test measurement was taken in February/March 2002, about 9 months after the pre-test. Multilevel regression analysis, which takes the hierarchical structure of the data into account, was used for the analysis. After taking provider-level variation into account and controlling for client characteristics, the analyses showed significant improvements in perceived quality of care and perceived access to services. Private provider participation in a franchise network helps improve client perceptions of quality of, and access to, services. Improvements in client perceptions of quality and access contribute to increased client loyalty to franchised clinics. Once increased client loyalty translates into higher client volumes, providers are likely to see the benefits of franchise participation. In turn, this should lead to

    2013-01-01

    Full Text Available Introduction: In South Africa, there are renewed efforts to strengthen primary health care and community health worker (CHW programmes. This article examines three South African CHW programmes, a small local non-governmental organisation (NGO, a local satellite of a national NGO, and a government-initiated service, that provide a range of services from home-based care, childcare, and health promotion to assist clients in overcoming poverty-related barriers to health care. Methods: The comparative case studies, located in Eastern Cape and Gauteng, were investigated using qualitative methods. Thematic analysis was used to identify factors that constrain and enable outreach services to improve access to care. Results: The local satellite (of a national NGO, successful in addressing multi-dimensional barriers to care, provided CHWs with continuous training focused on the social determinants of ill-health, regular context-related supervision, and resources such as travel and cell-phone allowances. These workers engaged with, and linked their clients to, agencies in a wide range of sectors. Relationships with participatory structures at community level stimulated coordinated responses from service providers. In contrast, an absence of these elements curtailed the ability of CHWs in the small NGO and government-initiated service to provide effective outreach services or to improve access to care. Conclusion: Significant investment in resources, training, and support can enable CHWs to address barriers to care by negotiating with poorly functioning government services and community participation structures.

  18. Ethnic minority, young onset, rare dementia type, depression: A case study of a Muslim male accessing UK dementia health and social care services.

    Regan, Jemma L

    2016-07-01

    A case study comprised of formal interviews, formal observations and informal discussions investigated the motivations and experiences accessing dementia care health and social care services for a Muslim, Pakistani male with dementia. Motivations derived from 'desperation' and an inability to access support from family or religious community. Experiences of accessing services were mostly negative. Dementia services were ill-informed about how to support persons with young onset dementia, with pre-existing mental health conditions, from an ethnic minority. Education and training to remove barriers to all dementia care services is required for persons with dementia, their families and within dementia services and religious communities. PMID:24858552

    Full Text Available Objective – To examine interlibrary loan (ILL request rates for open access (OA materials and determine how OA may affect resource sharing. This research updates the author’s previous study. Design – Quantitative analysis. Setting – A large, urban, public research university library system in the United States of America. Subjects – 1,557 open access ILL material requests among 23,531 total ILL requests submitted during the 2012 and 2013 fiscal years (July 2011-June 2013. Methods – The library has tracked and recorded OA requests that appear among ILL material requests since 2009. Using OCLC’s ILLiad software to manage ILL requests, they have implemented two custom routines. One routine is for open access searching on standard items, and uses software plugins to search across various open resources. All materials published prior to 1923 are treated as being in the public domain, so requests for these materials are automatically routed to this queue. The second custom routine is used for searching for OA electronic theses and dissertations, and is employed when the requested resource is not found in the library’s subscription resources. Other article requests are routed to the RapidILL service for open access availability. Main Results – The research presented reveals that ILL requests for OA materials exhibited a steady increase year over year, while overall ILL requests decreased slightly. This finding is true both for the fiscal years reported in this study and also the years since the author’s original study in 2011 (Baich, 2012. Of the 1,557 OA requests examined, 72% (n=1,135 were for journal articles, 8% (n=125 were for books or book chapters, 9% (n=140 were for theses or dissertations, 3% (n=54 were for conference papers, and 7% (n=105 were for reports. Library staff typically fill these article requests using gold OA or green OA sources. The researcher notes the difficulty in refining by source, though confirmed that

  20. Accessing community health services: challenges faced by poor people with disabilities in a rural community in South Africa

    Lisbet Grut

    2012-05-01

    Full Text Available Poor people with disabilities who live in poor rural societies experience unique problems in accessing health services. Their situation is influenced by multiple factors which unfold and interplay throughout the person’s life course. The difficulties do not only affect the person with a disability and his or her family, but also impact on the relevant care unit. The barriers are rooted in a life in poverty, upheld and maintained by poverty-reinforcing social forces of the past and the present, and reinforced by the lack of the person’s perspective of the health services. This article explores how difficulties may interact and influence access to and utilisation of health services, and how this may render health services out of reach even when they are available. The study reveals that non-compliance is not necessarily about neglect but could as well be a matter of lived poverty. The study was based on in-depth interviews with people with disabilities and family members, and semi-structured interviews with health personnel. The data analysis is contextual and interpretive. When offering health services to people with disabilities living in resource-poor settings, services should take into consideration the person’s history, the needs, and the resources and abilities of the family group. Rethinking access to health services should transcend a narrow medical institutionalization of health professional’s training, and include a patient’s perspective and a social vision in understanding and practice. Such rethinking requires health service models that integrate the skills of health professionals with the skills of disabled people and their family members. Such skills lie dormant at community level, and need to be recognized and utilized.

  3. Distributed Smart Grid Asset Control Strategies for Providing Ancillary Services

    Kalsi, Karanjit; Zhang, Wei; Lian, Jianming; Marinovici, Laurentiu D.; Moya, Christian; Dagle, Jeffery E.

    2013-10-30

    With large-scale plans to integrate renewable generation driven mainly by state-level renewable portfolio requirements, more resources will be needed to compensate for the uncertainty and variability associated with intermittent generation resources. Distributed assets can be used to mitigate the concerns associated with renewable energy resources and to keep costs down. Under such conditions, performing primary frequency control using only supply-side resources becomes not only prohibitively expensive but also technically difficult. It is therefore important to explore how a sufficient proportion of the loads could assume a routine role in primary frequency control to maintain the stability of the system at an acceptable cost. The main objective of this project is to develop a novel hierarchical distributed framework for frequency based load control. The framework involves two decision layers. The top decision layer determines the optimal gain for aggregated loads for each load bus. The gains are computed using decentralized robust control methods, and will be broadcast to the corresponding participating loads every control period. The second layer consists of a large number of heterogeneous devices, which switch probabilistically during contingencies so that aggregated power change matches the desired amount according to the most recently received gains. The simulation results show great potential to enable systematic design of demand-side primary frequency control with stability guarantees on the overall power system. The proposed design systematically accounts for the interactions between the total load response and bulk power system frequency dynamics. It also guarantees frequency stability under a wide range of time varying operating conditions. The local device-level load response rules fully respect the device constraints (such as temperature setpoint, compressor time delays of HVACs, or arrival and departure of the deferrable loads), which are crucial for implementing real load control programs. The promise of autonomous, Grid Friendly™ response by smart appliances in the form of under-frequency load shedding was demonstrated in the GridWise Olympic Peninsula Demonstration in 2006. Each controller monitored the power grid voltage signal and requested that electrical load be shed by its appliance whenever electric power-grid frequency fell below 59.95 Hz. The controllers and their appliances responded reliably to each shallow under-frequency event, which was an average of one event per day and shed their loads for the durations of these events. Another objective of this project was to perform extensive simulation studies to investigate the impact of a population of Grid Friendly™ Appliances (GFAs) on the bulk power system frequency stability. The GFAs considered in this report are represented as demonstration units with water heaters individually modeled.

    2014-01-01

    Full Text Available Background. Tuberculosis (TB remains a significant global public health problem with known gender-related (male versus female disparities. We reviewed the qualitative evidence (written/spoken narrative for gender-related differences limiting TB service access from symptom onset to treatment initiation. Methods. Following a systematic process, we searched 12 electronic databases, included qualitative studies that assessed gender differences in accessing TB diagnostic and treatment services, abstracted data, and assessed study validity. Using a modified “inductive coding” system, we synthesized emergent themes within defined barriers and delays limiting access at the individual and provider/system levels and examined gender-related differences. Results. Among 13,448 studies, 28 studies were included. All were conducted in developing countries and assessed individual-level barriers; 11 (39% assessed provider/system-level barriers, 18 (64% surveyed persons with suspected or diagnosed TB, and 7 (25% exclusively surveyed randomly sampled community members or health care workers. Each barrier affected both genders but had gender-variable nature and impact reflecting sociodemographic themes. Women experienced financial and physical dependence, lower general literacy, and household stigma, whereas men faced work-related financial and physical barriers and community-based stigma. Conclusions. In developing countries, barriers limiting access to TB care have context-specific gender-related differences that can inform integrated interventions to optimize TB services.

  6. eTriage--a novel, web-based triage and booking service: enabling timely access to sexual health clinics.

    Jones, R; Menon-Johansson, A; Waters, A M; Sullivan, A K

    2010-01-01

    In recent years, the sexual health of the nation has risen in profile. We face increasing demands and targets, in particular the 48-hour waiting time directive, and as a result clinic access has become a priority. eTriage is a novel, secure, web-based service designed specifically to increase access to our clinics. It has proved a popular booking method, providing access to 10% of all appointments across the Directorate within six months of introduction. KC60 analyses revealed that the majority of users (58%) underwent asymptomatic screening with the remainder having some degree of pathology. There was a greater percentage prevalence of human papilloma virus, chlamydia, non-specific urethritis, gonorrhoea, herpes and trichomonas in the eTriage population when compared with the general clinic population. A notes review illustrated a high degree of concordance between data entered on eTriage registration and clinical review (97%). A patient survey revealed high levels of patient satisfaction with the service. As an adjunct to our existing booking services, eTriage has served to increase patient choice and has proved itself to be a safe, efficient and effective means of improving patient access.

  7. Low-cost MCM-D fabrication and assembly from MIDAS: the multichip module interconnect designer's access service

    Peltier, Jennifer; Hansford, Wes

    1997-06-01

    The MCM Designers' Access Service (MIDAS) allows designers to obtain prototype and small quantities of MCMs. To date the service has processed designs from industry, government and major universities. The service currently accesses processes at the following MCM-D foundries: nChip/Flextronics in San Jose, CA; Micromodule Systems in Cupertino, CA; and IBM Microelectronics in Hopewell Junction, NY. MIDAS provides a low cost service achieved through a multiproject environment where the customers share tooling and substrate manufacturing costs. The service offers design support, distributes foundry design kits, groups the projects onto regularly scheduled runs, places orders and supplies fully assembled modules. As well, MIDAS offers a limited selection of open tooled, second-level packages, bare tested die, and test sockets to aid with the design process. Often when investigating implementation of MCMs into a working system designers need a prototype. In many cases a foundry prefers to handle only high volume orders or imposes minimum purchase quantities. These may likely exceed the entire project budget. MIDAS functions as a technology enabler by supplying the designers with an interface `transparent' to the fabricator and common to multiple vendors. Foundries prefer to work with a single source who coordinates the details of multiple orders to spare valuable overhead. By completing front-end foundry tasks such as data preparation and mask fabrication and by grouping multiple users together on a run, MIDAS serves this purpose. Certain design conditions such as footprint size and I/O ring, layer stacking and number of layers exist to establish uniformity amongst the unrelated customers. This paper discusses the history of the service, the operating guidelines and presents an overview of how to access the service for MCM fabrication.

  8. Unofficial policy: access to housing, housing information and social services among homeless drug users in Hartford, Connecticut

    Corbett A Michelle

    2007-03-01

    Full Text Available Abstract Background Much research has shown that the homeless have higher rates of substance abuse problems than housed populations and that substance abuse increases individuals' vulnerability to homelessness. However, the effects of housing policies on drug users' access to housing have been understudied to date. This paper will look at the "unofficial" housing policies that affect drug users' access to housing. Methods Qualitative interviews were conducted with 65 active users of heroin and cocaine at baseline, 3 and 6 months. Participants were purposively sampled to reflect a variety of housing statuses including homeless on the streets, in shelters, "doubled-up" with family or friends, or permanently housed in subsidized, unsubsidized or supportive housing. Key informant interviews and two focus group interviews were conducted with 15 housing caseworkers. Data were analyzed to explore the processes by which drug users receive information about different housing subsidies and welfare benefits, and their experiences in applying for these. Results A number of unofficial policy mechanisms limit drug users' access to housing, information and services, including limited outreach to non-shelter using homeless regarding housing programs, service provider priorities, and service provider discretion in processing applications and providing services. Conclusion Unofficial policy, i.e. the mechanisms used by caseworkers to ration scarce housing resources, is as important as official housing policies in limiting drug users' access to housing. Drug users' descriptions of their experiences working with caseworkers to obtain permanent, affordable housing, provide insights as to how access to supportive and subsidized housing can be improved for this population.

  9. "It is an Issue of not Knowing Where to Go": Service Providers' Perspectives on Challenges in Accessing Social Support and Services by Immigrant Mothers of Children with Disabilities.

    Khanlou, Nazilla; Haque, Nasim; Sheehan, Sinead; Jones, Gail

    2015-12-01

    In Canada little is known about the challenges immigrant mothers of children with disabilities encounter in accessing formal and informal social support. This paper presents the perspectives of service providers on the mothers' challenges. Data was collected from 27 service providers in Toronto, Canada in 2012 through in-depth interviews. The interview guide was informed by published literature on families of children with special needs. Level one analyses entailed descriptive analyses; and level two consisted of applying House's 4 domains of social support to organize the themes. Following House's domains, challenges to (1) Structural support, (2) Instrumental support, (3) Emotional support, and (4) Perception of support were identified. Among providers who work with families of children with disabilities there is recognition of the mothers' particular challenges in light of their immigration status. Language and communication are significant barriers for immigrant mothers in accessing social support. PMID:25376126

    Full Text Available It is recognized and accepted that social economy has a significant contribution within the area of social inclusion policies. The intervention areas regarded are extremely diverse: professional education and training, employment policies, social and socio‐medical services, social insurances, the banking and cultural environment,leisure activities, proximity services designed for the population with social exclusion risk etc. This study focuses on some of the ways where social economy mechanisms could be introduced in the field of health protection from Romania.Accepting and recognizing the utility of the mutual insurance type structures is desirable for the increase of the preconditions of a real equity within the access tothe health care services, including the vulnerable groups, without endangering social solidarity, focusing on the service needs and guaranteeing the active participation to the formation and management of the funds thus created.

  12. Access to Basic HIV-Related Services and PrEP Acceptability among Men Who Have sex with Men Worldwide: Barriers, Facilitators, and Implications for Combination Prevention

    George Ayala

    2013-01-01

    Full Text Available Introduction. Men who have sex with men (MSM are disproportionately impacted by HIV globally. Easily accessible combination HIV prevention strategies, tailored to the needs of MSM, are needed to effectively address the AIDS pandemic. Methods and Materials. We conducted a cross-sectional study among MSM (n=3748 from 145 countries from April to August 2012. Using multivariable random effects models, we examined factors associated with acceptability of preexposure prophylaxis (PrEP and access to condoms, lubricants, HIV testing, and HIV treatment. Results. Condoms and lubricants were accessible to 35% and 22% of all respondents, respectively. HIV testing was accessible to 35% of HIV-negative respondents. Forty-three percent of all HIV-positive respondents reported that antiretroviral therapy was easily accessible. Homophobia, outness, and service provider stigma were significantly associated with reduced access to services. Conversely, community engagement, connection to gay community, and comfort with service providers were associated with increased access. PrEP acceptability was associated with lower PrEP-related stigma, less knowledge about PrEP, less outness, higher service provider stigma, and having experienced violence for being MSM. Conclusions. Ensuring HIV service access among MSM will be critical in maximizing the potential effectiveness of combination approaches, especially given the interdependence of both basic and newer interventions like PrEP. Barriers and facilitators of HIV service access for MSM should be better understood and addressed.

    Hayes, Sharon; Napolitano, Melissa; Hufnagel, Katrina

    2016-01-01

    Background More than one third of college students who are overweight or obese are in need of weight loss programs tailored to college students. However, the availability and accessibility of these programs is unknown. Objective The aim of this study is to examine the availability and ease of access to weight loss programs for students at 10 universities with the largest undergraduate enrollment. Methods The 10 public universities with the largest student bodies with a mean (SD) undergraduate enrollment of 41,122 (7657) students were examined. The websites of the universities were assessed to determine the availability of weight loss programs. Services for high-risk health needs common to university campuses (ie, alcohol and other drugs, victim services, sexual health, and eating disorders) were searched. Results Of the universities searched, 3 (30%, 3/10) offered weight loss programming, however, none met the predetermined criteria. Comparatively, all schools (100%, 10/10) offered no-cost and continual enrollment programming for the other high-risk health needs. Conclusions There are limited weight loss services available to undergraduate students compared with other university services. Collaboration between existing college health service providers is suggested for the delivery of appropriate programming for overweight and obese undergraduates wanting to lose weight. PMID:27278261

  15. Multi-service small-cell cloud wired/wireless access network based on tunable optical frequency comb

    Xiang, Yu; Zhou, Kun; Yang, Liu; Pan, Lei; Liao, Zhen-wan; Zhang, Qiang

    2015-11-01

    In this paper, we demonstrate a novel multi-service wired/wireless integrated access architecture of cloud radio access network (C-RAN) based on radio-over-fiber passive optical network (RoF-PON) system, which utilizes scalable multiple- frequency millimeter-wave (MF-MMW) generation based on tunable optical frequency comb (TOFC). In the baseband unit (BBU) pool, the generated optical comb lines are modulated into wired, RoF and WiFi/WiMAX signals, respectively. The multi-frequency RoF signals are generated by beating the optical comb line pairs in the small cell. The WiFi/WiMAX signals are demodulated after passing through the band pass filter (BPF) and band stop filter (BSF), respectively, whereas the wired signal can be received directly. The feasibility and scalability of the proposed multi-service wired/wireless integrated C-RAN are confirmed by the simulations.

  2. Health systems and access to antiretroviral drugs for HIV in Southern Africa: service delivery and human resources challenges.

    Schneider, Helen; Blaauw, Duane; Gilson, Lucy; Chabikuli, Nzapfurundi; Goudge, Jane

    2006-05-01

    Without strengthened health systems, significant access to antiretroviral (ARV) therapy in many developing countries is unlikely to be achieved. This paper reflects on systemic challenges to scaling up ARV access in countries with both massive epidemics and weak health systems. It draws on the authors' experience in southern Africa and the World Health Organization's framework on health system performance. Whilst acknowledging the still significant gap in financing, the paper focuses on the challenges of reorienting service delivery towards chronic disease care and the human resource crisis in health systems. Inadequate supply, poor distribution, low remuneration and accelerated migration of skilled health workers are increasingly regarded as key systems constraints to scaling up of HIV treatment. Problems, however, go beyond the issue of numbers to include productivity and cultures of service delivery. As more countries receive funds for antiretroviral access programmes, strong national stewardship of these programmes becomes increasingly necessary. The paper proposes a set of short- and long-term stewardship tasks, which include resisting the verticalisation of HIV treatment, the evaluation of community health workers and their potential role in HIV treatment access, international action on the brain drain, and greater investment in national human resource functions of planning, production, remuneration and management.

    2013-01-01

    运行机组间无功出力分配是发电厂AVC系统的重要技术环节,分配策略的优劣影响着AVC控制的安全性及发电厂运行的经济性。从提高发电厂收益角度,提出了基于无功辅助服务补偿的发电厂AVC系统机组无功出力分配策略,建立了优化模型。该优化模型考虑了发电厂参与无功辅助服务后机组及变压器损耗增加的成本,在满足调度机构AVC系统下发的控制目标及机组安全运行等约束条件的前提下,以电厂收益最大为优化目标,求取参与AVC控制机组的无功出力控制量并下发相应机组执行。算例仿真验证了基于无功辅助服务补偿后发电厂运行机组间无功出力分配的有效性,能在满足调压要求的同时明显地提高电厂的经济效益。%The reactive power output allocation for generators is an important technical link of automatic voltage control (AVC) system in power plant. The allocation strategy affects the security of the AVC control and operation economy of power plant. In order to improve the profits of the power plant, a reactive power allocation strategy based on the reactive power ancillary services (RPAS) compensation is proposed, and the optimization model is established. The model considers the increasing cost of units and transformer loss when the power plant adopts the RPAS. Under the condition of satisfying the constraints such as the control target of AVC system of the dispatching department and secure operation domain of generators, and taking the maximum profits of power plant as the optimization objective, the model solves the controlling quantity of reactive outputs of AVC generators and then they are implemented by corresponding units. The method is proved to be effective in the simulation and the strategy can satisfy the requirements of voltage regulation and significantly improve the economic efficiency of the power plant.

  4. Chinese Doctors Connecting to the English Publishing World: Literature Access, Editorial Services, and Training in Publication Skills

    Yongyan Li

    2013-12-01

    Full Text Available In the literature on academic publishing, little attention has been paid to the needs and concerns of non-English-speaking researchers in professional contexts. This paper addresses the gap in that literature by providing insights into the situation with medical doctors in China. Following an overview of the broad picture, I will report a case study, which was conducted at a major hospital in East China and which aimed at exploring how a group of orthopedic surgeons access the English medical literature and to what extent they seek the support of editorial services and training in academic writing/publication skills. The results of the study show that the participant doctors tend to rely on their students or overseas personal connections for access to full-text medical literature, and they have generally had limited experience with language editorial services and academic writing/publication skills seminars. The paper ends by discussing some challenges while proposing recommendations for enhancing Chinese doctors’ access to the full-text medical literature, as well as their understanding of the kind of support that can be provided by editorial services and training in publication skills.

    Full Text Available Public authorities and national healthcare service providers across the European Union and beyond are increasingly under pressure to deliver better services with diminishing resources. Users, quite rightly, demand a high standard of service and increasingly also convenience focused on the needs of the users rather than how the services are organised to deliver them. Users, on the whole, also prefer to be supported in their homes, and be free to move as much as possible. While users without impairments and generally well provided for, there are increasingly also users who have special needs, including the aged and those with a range of physical and mental disabilities who are unable to make effective use of such services from their homes due to the lack of proactive and accessible services. The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered for free or purchased through some central form of a marketplace repository.

    2011-03-01

    Full Text Available Abstract Background HIV remains responsible for an estimated 40% of mortality in South African pregnant women and their children. To address these avoidable deaths, eligibility criteria for antiretroviral therapy (ART in pregnant women were revised in 2010 to enhance ART coverage. With greater availability of HIV services in public health settings and increasing government attention to poor maternal-child health outcomes, this study used the patient's journey through the continuum of maternal and child care as a framework to track and document women's experiences of accessing ART and prevention of mother-to-child HIV transmission (PMTCT programmes in the Eastern Cape (three peri-urban facilities and Gauteng provinces (one academic hospital. Results In-depth interviews identified considerable weaknesses within operational HIV service delivery. These manifested as missed opportunities for HIV testing in antenatal care due to shortages of test kits; insufficient staff assigned to HIV services; late payment of lay counsellors, with consequent absenteeism; and delayed transcription of CD4 cell count results into patient files (required for ART initiation. By contrast, individual factors undermining access encompassed psychosocial concerns, such as fear of a positive test result or a partner's reaction; and stigma. Data and information systems for monitoring in the three peri-urban facilities were markedly inadequate. Conclusions A single system- or individual-level delay reduced the likelihood of women accessing ART or PMTCT interventions. These delays, when concurrent, often signalled wholesale denial of prevention and treatment. There is great scope for health systems' reforms to address constraints and weaknesses within PMTCT and ART services in South Africa. Recommendations from this study include: ensuring autonomy over resources at lower levels; linking performance management to facility-wide human resources interventions; developing

    Easy, efficient and comprehensive access to data, data products, scientific services and scientific software is a key ingredient in enabling research at the frontiers of science. Organizing this access across the European Research Infrastructures in the field of seismology, so that it best serves user needs, takes advantage of state-of-the-art ICT solutions, provides cross-domain interoperability, and is organizationally and financially sustainable in the long term, is the core challenge of the implementation phase of the Thematic Core Service (TCS) Seismology within the EPOS-IP project. Building upon the existing European-level infrastructures ORFEUS for seismological waveforms, EMSC for seismological products, and EFEHR for seismological hazard and risk information, and implementing a pilot Computational Earth Science service starting from the results of the VERCE project, the work within the EPOS-IP project focuses on improving and extending the existing services, aligning them with global developments, to at the end produce a well coordinated framework that is technically, organizationally, and financially integrated with the EPOS architecture. This framework needs to respect the roles and responsibilities of the underlying national research infrastructures that are the data owners and main providers of data and products, and allow for active input and feedback from the (scientific) user community. At the same time, it needs to remain flexible enough to cope with unavoidable challenges in the availability of resources and dynamics of contributors. The technical work during the next years is organized in four areas: - constructing the next generation software architecture for the European Integrated (waveform) Data Archive EIDA, developing advanced metadata and station information services, fully integrate strong motion waveforms and derived parametric engineering-domain data, and advancing the integration of mobile (temporary) networks and OBS deployments in

  13. Ancillary study management systems: a review of needs

    Nelson Elizabeth K

    2013-01-01

    Full Text Available Abstract Background The valuable clinical data, specimens, and assay results collected during a primary clinical trial or observational study can enable researchers to answer additional, pressing questions with relatively small investments in new measurements. However, management of such follow-on, “ancillary” studies is complex. It requires coordinating across institutions, sites, repositories, and approval boards, as well as distributing, integrating, and analyzing diverse data types. General-purpose software systems that simplify the management of ancillary studies have not yet been explored in the research literature. Methods We have identified requirements for ancillary study management primarily as part of our ongoing work with a number of large research consortia. These organizations include the Center for HIV/AIDS Vaccine Immunology (CHAVI, the Immune Tolerance Network (ITN, the HIV Vaccine Trials Network (HVTN, the U.S. Military HIV Research Program (MHRP, and the Network for Pancreatic Organ Donors with Diabetes (nPOD. We also consulted with researchers at a range of other disease research organizations regarding their workflows and data management strategies. Lastly, to enhance breadth, we reviewed process documents for ancillary study management from other organizations. Results By exploring characteristics of ancillary studies, we identify differentiating requirements and scenarios for ancillary study management systems (ASMSs. Distinguishing characteristics of ancillary studies may include the collection of additional measurements (particularly new analyses of existing specimens; the initiation of studies by investigators unaffiliated with the original study; cross-protocol data pooling and analysis; pre-existing participant consent; and pre-existing data context and provenance. For an ASMS to address these characteristics, it would need to address both operational requirements (e.g., allocating existing specimens and data

  15. Enabling the maximum number of people to access essential services will not be possible without private sector involvement and appropriate pricing of the services concerned

    Luc Rigouzzo

    2012-06-01

    Full Text Available Private sector provision of basic services (water, energy, financial services and housing for people in developing countries is a necessity if we really want to try to curb poverty. However, ‘traditional’ private funding is not spontaneously directed towards these sectors, largely as a result of rejecting the idea that poor population groups should ‘pay’ for essential services; an issue that has often been the subject of opposition campaigns mounted by social stakeholders. Nevertheless, there are many, many examples to show that given the impact of these services on their quality of life, consumers in these countries - and especially those at the ‘bottom of the pyramid’ - are prepared to pay for them as long as they have access to a high-quality service. In these sectors, the nominal cost of the service concerned matters much less than its opportunity cost and the impact it will have on the lives of those who benefit from it. Very often, this service may even be paid for in advance as a way of enabling families to gain greater control over the expenditure they can devote to obtaining it.It is, however, important to distinguish between the supply of essential services and those of consumer goods, and - of course - to avoid abuses. In any event, the possibility of building financially-balanced models is what governs the process of securing sufficient funding from local and international financial institutions. In this area, as in others, the way forward is probably the happy medium: avoiding the excesses of overpricing, but accepting the need to maintain profitable economic models. These should enable investors to receive a level of profit that encourages them to continue and increase their investment, thereby increasing the number of recipients as quickly as possible. Aspiring to build social models that reject the ambition to achieve a reasonable profit and rule out any distribution of dividends to shareholders is to condemn the

  16. Enhanced Class-of-Service Oriented Packet Scheduling Scheme for EPON Access Networks

    Han, Intark; Park, Hong-Shik; Han, Man-Soo

    A fast class-of-service oriented packet scheduling (FCOPS) has a service fairness problem since a credit pool for a service class is initialized at the beginning of a transmission cycle whose starting moment is fixed at a specific ONU. To remedy the service unfairness of FCOPS, we suggest an enhanced class-of-service oriented packet scheduling (ECOPS) that uses a new initialization cycle whose starting moment is fairly distributed to each ONU. Also, ECOPS generates a colorless grant to utilize the resource wastage, when traffic is light and the total sum of grants of an ONU is less than a minimum size. Using simulation, we validate ECOPS as superior to FCOPS in the mean delay and the service fairness.

  17. Medical Researchers' Ancillary Care Obligations: The Relationship-Based Approach.

    Olson, Nate W

    2016-06-01

    In this article, I provide a new account of the basis of medical researchers' ancillary care obligations. Ancillary care in medical research, or medical care that research participants need but that is not required for the validity or safety of a study or to redress research injuries, is a topic that has drawn increasing attention in research ethics over the last ten years. My view, the relationship-based approach, improves on the main existing theory, Richardson and Belsky's 'partial-entrustment model', by avoiding its problematic restriction on the scope of health needs for which researchers could be obligated to provide ancillary care. Instead, it grounds ancillary care obligations in a wide range of morally relevant features of the researcher-participant relationship, including the level of engagement between researchers and participants, and weighs these factors against each other. I argue that the level of engagement, that is, the duration and intensity of interactions, between researchers and participants matters for ancillary care because of its connection to the meaningfulness of a relationship, and I suggest that other morally relevant features can be grounded in researchers' role obligations.

  18. Ancillary effects of selected acid deposition control policies

    Moe, R.J.; Lyke, A.J.; Nesse, R.J.

    1986-08-01

    NAPAP is examining a number of potential ways to reduce the precursors (sulfur dioxide and nitrogen oxides) to acid deposition. However, the policies to reduce acid deposition will have other physical, biological and economic effects unrelated to acid deposition. For example, control policies that reduce sulfur dioxide emissions may also increase visibility. The effects of an acid deposition policy that are unrelated to acid deposition are referred to as ''ancillary'' effects. This reserch identifies and characterizes the principle physical and economic ancillary effects associated with acid deposition control and mitigation policies. In this study the ancillary benefits associated with four specific acid deposition policy options were investigated. The four policy options investigated are: (1) flue gas desulfurization, (2) coal blending or switching, (3) reductions in automobile emissions of NO/sub x/, and (4) lake liming. Potential ancillary benefits of each option were identified and characterized. Particular attention was paid to the literature on economic valuation of potential ancillary effects.

  19. PAHO'S Strategy for Universal Access to Health and Universal Health Coverage: implications for health services and hospitals in LAC.

    Holder, Reynaldo; Fabrega, Ricardo

    2015-01-01

    Moving towards Universal Access to Health and Universal Health Coverage (UAH/UHC) is an imperative task on the health agenda for the Americas. The Directing Council of the Pan American Health Organization (PAHO) recently approved resolution CD53.R14, titled Strategy for Universal Access to Health and Universal Health Coverage. From the perspective of the Region of the Americas, UAH/UHC "imply that all people and communities have access, without any kind of discrimination, to comprehensive, appropriate and timely, quality health services determined at the national level according to needs, as well as access to safe, affordable, effective, quality medicines, while ensuring that the use of these services does not expose users to financial hardship, especially groups in conditions of vulnerability". PAHO's strategic approach to UAH/UHC sets out four specific lines of action toward effective universal health systems. The first strategic line proposes: a) implementation of integrated health services delivery networks (IHDSNs) based on primary health care as the key strategy for reorganizing, redefining and improving healthcare services in general and the role of hospitals in particular; and b) increasing the response capacity of the first level of care. An important debate initiated in 2011 among hospital and healthcare managers in the region tried to redefine the role of hospitals in the context of IHSDNs and the emerging UAH/UHC movement. The debates resulted in agreements around three main propositions: 1) IHSDNs cannot be envisioned without hospitals; 2) The status-quo and current hospital organizational culture makes IHSDNs inviable; and 3) Without IHSDNs, hospitals will not be sustainable. This process, that predates the approval of PAHO's UAH/UHC resolution, now becomes more relevant with the recognition that UAH/UHC cannot be attained without a profound change in healthcare service and particularly in hospitals. In this context, a set of challenges both for

  20. Priorities and realities: addressing the rich-poor gaps in health status and service access in Indonesia

    Utomo Budi

    2011-11-01

    Full Text Available Abstract Introduction Over the past four decades, the Indonesian health care system has greatly expanded and the health of Indonesian people has improved although the rich-poor gap in health status and service access remains an issue. The government has been trying to address these gaps and intensify efforts to improve the health of the poor following the economic crisis in 1998. Methods This paper examines trends and levels in socio-economic inequity of health and identifies critical factors constraining efforts to improve the health of the poor. Quantitative data were taken from the Indonesian Demographic Health Surveys and the National Socio-Economic Surveys, and qualitative data were obtained from interviews with individuals and groups representing relevant stakeholders. Results The health of the population has improved as indicated by child mortality decline and the increase in community access to health services. However, the continuing prevalence of malnourished children and the persisting socio-economic inequity of health suggest that efforts to improve the health of the poor have not yet been effective. Factors identified at institution and policy levels that have constrained improvements in health care access and outcomes for the poor include: the high cost of electing formal governance leaders; confused leadership roles in the health sector; lack of health inequity indicators; the generally weak capacity in the health care system, especially in planning and budgeting; and the leakage and limited coverage of programs for the poor. Conclusions Despite the government's efforts to improve the health of the poor, the rich-poor gap in health status and service access continues. Factors at institutional and policy levels are critical in contributing to the lack of efficiency and effectiveness for health programs that address the poor.

  3. Cancer control in developing countries: using health data and health services research to measure and improve access, quality and efficiency

    Kangolle Alfred CT

    2010-10-01

    Full Text Available Abstract Background Cancer is a rapidly increasing problem in developing countries. Access, quality and efficiency of cancer services in developing countries must be understood to advance effective cancer control programs. Health services research can provide insights into these areas. Discussion This article provides an overview of oncology health services in developing countries. We use selected examples from peer-reviewed literature in health services research and relevant publicly available documents. In spite of significant limitations in the available data, it is clear there are substantial barriers to access to cancer control in developing countries. This includes prevention, early detection, diagnosis/treatment and palliation. There are also substantial limitations in the quality of cancer control and a great need to improve economic efficiency. We describe how the application of health data may assist in optimizing (1 Structure: strengthening planning, collaboration, transparency, research development, education and capacity building. (2 Process: enabling follow-up, knowledge translation, patient safety and quality assurance. (3 Outcome: facilitating evaluation, monitoring and improvement of national cancer control efforts. There is currently limited data and capacity to use this data in developing countries for these purposes. Summary There is an urgent need to improve health services for cancer control in developing countries. Current resources and much-needed investments must be optimally managed. To achieve this, we would recommend investment in four key priorities: (1 Capacity building in oncology health services research, policy and planning relevant to developing countries. (2 Development of high-quality health data sources. (3 More oncology-related economic evaluations in developing countries. (4 Exploration of high-quality models of cancer control in developing countries. Meeting these needs will require national, regional and

  4. Territorial user rights for fisheries as ancillary instruments for marine coastal conservation in Chile.

    Gelcich, Stefan; Fernández, Miriam; Godoy, Natalio; Canepa, Antonio; Prado, Luis; Castilla, Juan Carlos

    2012-12-01

    Territorial user rights for fisheries have been advocated as a way to achieve sustainable resource management. However, few researchers have empirically assessed their potential as ancillary marine conservation instruments by comparing them to no-take marine protected areas. In kelp (Lessonia trabeculata) forests of central Chile, we compared species richness, density, and biomass of macroinvertebrates and reef fishes among territorial-user-right areas with low-level and high-level enforcement, no-take marine protected areas, and open-access areas in 42 100-m subtidal transects. We also assessed structural complexity of the kelp forest and substratum composition. Multivariate randomized permutation tests indicated macroinvertebrate and reef fish communities associated with the different access regimes differed significantly. Substratum composition and structural complexity of kelp forest did not differ among access regimes. Univariate analyses showed species richness, biomass, and density of macroinvertebrates and reef fishes were greater in highly enforced territorial-user-right areas and no-take marine protected areas than in open-access areas. Densities of macroinvertebrates and reef fishes of economic importance were not significantly different between highly enforced territorial-user-right and no-take marine protected areas. Densities of economically important macroinvertebrates in areas with low-level enforcement were significantly lower than those in areas with high-level enforcement and no-take marine protected areas but were significantly higher than in areas with open access. Territorial-user-right areas could be important ancillary conservation instruments if they are well enforced. PMID:22971114

  8. Access to dental care-parents' and caregivers' views on dental treatment services for people with disabilities.

    Prabhu, Neeta T

    2010-03-01

    The goal of this study was to elicit the views of patients or parents\\/caregivers of patients with disabilities regarding access to dental care. A questionnaire was generated both from interviews with patients\\/parents\\/caregivers already treated under sedation or general anesthesia as well as by use of the Delphi technique with other stakeholders. One hundred thirteen patients from across six community dental clinics and one dental hospital were included. Approximately, 38% of the subjects used a general dental practitioner and 35% used the community dental service for their dental care, with only 27% using the hospital dental services. Overall waiting time for an appointment at the secondary care setting was longer than for the primary care clinics. There was a high rate of parent\\/caregiver satisfaction with dental services and only five patients reported any difficulty with travel and access to clinics. This study highlights the need for a greater investment in education and training to improve skills in the primary dental care sector.

  9. Hybrid Terrestrial-Satellite DVB/IP Infrastructure in Overlay Constellations for Triple-Play Services Access in Rural Areas

    A. Bourdena

    2010-01-01

    Full Text Available This paper discusses the convergence of digital broadcasting and Internet technologies, by elaborating on the design, implementation, and performance evaluation of a hybrid terrestrial/satellite networking infrastructure, enabling triple-play services access in rural areas. At local/district level, the paper proposes the exploitation of DVB-T platforms in regenerative configurations for creating terrestrial DVB/IP backhaul between the core backbone (in urban areas and a number of intermediate communication nodes distributed within the DVB-T broadcasting footprint (in rural areas. In this way, triple play services that are available at the core backbone, are transferred via the regenerative DVB-T/IP backhaul to the entire district and can be accessed by rural users via the corresponding intermediate node. On the other hand, at regional/national level, the paper proposes the exploitation of a satellite interactive digital video broadcasting platform (DVB S2/RCS as an overlay network that interconnects the regenerative DVB-T/IP platforms, as well as individual users, and services providers, to each other. Performance of the proposed hybrid terrestrial/satellite networking environment is validated through experimental tests that were conducted under real transmission/reception conditions (for the terrestrial segment and via simulation experiments (for the satellite segment at a prototype network infrastructure.

  10. Interactive access to LP DAAC satellite data archives through a combination of open-source and custom middleware web services

    Davis, Brian N.; Werpy, Jason; Friesz, Aaron M.; Impecoven, Kevin; Quenzer, Robert; Maiersperger, Tom; Meyer, David J.

    2015-01-01

    Current methods of searching for and retrieving data from satellite land remote sensing archives do not allow for interactive information extraction. Instead, Earth science data users are required to download files over low-bandwidth networks to local workstations and process data before science questions can be addressed. New methods of extracting information from data archives need to become more interactive to meet user demands for deriving increasingly complex information from rapidly expanding archives. Moving the tools required for processing data to computer systems of data providers, and away from systems of the data consumer, can improve turnaround times for data processing workflows. The implementation of middleware services was used to provide interactive access to archive data. The goal of this middleware services development is to enable Earth science data users to access remote sensing archives for immediate answers to science questions instead of links to large volumes of data to download and process. Exposing data and metadata to web-based services enables machine-driven queries and data interaction. Also, product quality information can be integrated to enable additional filtering and sub-setting. Only the reduced content required to complete an analysis is then transferred to the user.

    Aleman, Alicia; Olsen, Lola; Ritz, Scott; Morahan, Michael; Cepero, Laurel; Stevens, Tyler

    2011-01-01

    NASA's Global Change Master Directory provides the scientific community with the ability to discover, access, and use Earth science data, data-related services, and climate diagnostics worldwide. The GCMD offers descriptions of Earth science data sets using the Directory Interchange Format (DIF) metadata standard; Earth science related data services are described using the Service Entry Resource Format (SERF); and climate visualizations are described using the Climate Diagnostic (CD) standard. The DIF, SERF and CD standards each capture data attributes used to determine whether a data set, service, or climate visualization is relevant to a user's needs. Metadata fields include: title, summary, science keywords, service keywords, data center, data set citation, personnel, instrument, platform, quality, related URL, temporal and spatial coverage, data resolution and distribution information. In addition, nine valuable sets of controlled vocabularies have been developed to assist users in normalizing the search for data descriptions. An update to the GCMD's search functionality is planned to further capitalize on the controlled vocabularies during database queries. By implementing a dynamic keyword "tree", users will have the ability to search for data sets by combining keywords in new ways. This will allow users to conduct more relevant and efficient database searches to support the free exchange and re-use of Earth science data. http://gcmd.nasa.gov/

  18. Extending Binary Large Object Support to Open Grid Services Architecture-Data Access and Integration Middleware Client Toolkit

    Kiran K. Patnaik

    2011-01-01

    Full Text Available Problem statement: OGSA-DAI middleware allows data resources to be federated and accessed via web services on the web or within grids or clouds. It provides a client API for writing programs that access the exposed databases. Migrating existing applications to the new technology and using a new API to access the data of DBMS with BLOB is difficult and discouraging. A JDBC Driver is a much convenient alternative to existing mechanism and provides an extension to OGSA-DAI middleware and allows applications to use databases exposed in a grid through the OGSA-DAI 3.0. However, the driver does not support Binary Large Objects (BLOB. Approach: The driver is enhanced to support BLOB using the OGSA-DAI Client API. It transforms the JDBC calls into an OGSA-DAI workflow request and sends it to the server using Web Services (WS. The client API of OGSA-DAI uses activities that are connected to form a workflow and executed using a pipeline. This workflow mechanism is embedded into the driver. The WS container dispatches the request to the OGSA-DAI middleware for processing and the result is then transformed back to an instance of ResultSet implementation using the OGSA-DAI Client API, before it is returned to the user. Results: Test on handling of BLOBs (images, flash files and videos ranging from size 1 KB to size 2 GB were carried out on Oracle, MySQL and PostgreSQL databases using our enhanced JDBC driver and it performed well. Conclusion: The enhanced JDBC driver now can offer users, with no experience in Grid computing specifically on OGSA-DAI, the possibility to give their applications the ability to access databases exposed on the grid with minimal effort.

    Introduction Free or low-cost HIV testing, condoms, and lubricants are foundational HIV prevention strategies, yet are often inaccessible for men who have sex with men (MSM). In the global context of stigma and poor healthcare access, transgender (trans) MSM may face additional barriers to HIV prevention services. Drawing on data from a global survey of MSM, we aimed to describe perceived access to prevention services among trans MSM, examine associations between stigma and access, and compare access between trans MSM and cisgender (non-transgender) MSM. Methods The 2014 Global Men's Health and Rights online survey was open to MSM (inclusive of trans MSM) from any country and available in seven languages. Baseline data (n=3857) were collected from July to October 2014. Among trans MSM, correlations were calculated between perceived service accessibility and anti-transgender violence, healthcare provider stigma, and discrimination. Using a nested matched-pair study design, trans MSM were matched 4:1 to cisgender MSM on age group, region, and HIV status, and conditional logistic regression models compared perceived access to prevention services by transgender status. Results About 3.4% of respondents were trans men, of whom 69 were included in the present analysis. The average trans MSM participant was 26 to 35 years old (56.5%); lived in western Europe, North America, or Oceania (75.4%); and reported being HIV-negative (98.6%). HIV testing, condoms, and lubricants were accessible for 43.5, 53.6, and 26.1% of trans MSM, respectively. Ever having been arrested or convicted due to being trans and higher exposure to healthcare provider stigma in the past six months were associated with less access to some prevention services. Compared to matched cisgender controls, trans MSM reported significantly lower odds of perceived access to HIV testing (OR=0.57, 95% CI=0.33, 0.98) and condom-compatible lubricants (OR=0.54, 95% CI=0.30, 0.98).

  9. Universalization of access to modern energy services in Indian households-Economic and policy analysis

    Provision of modern energy services for cooking (with gaseous fuels) and lighting (with electricity) is an essential component of any policy aiming to address health, education or welfare issues; yet it gets little attention from policy-makers. Secure, adequate, low-cost energy of quality and convenience is core to the delivery of these services. The present study analyses the energy consumption pattern of Indian domestic sector and examines the urban-rural divide and income energy linkage. A comprehensive analysis is done to estimate the cost for providing modern energy services to everyone by 2030. A public-private partnership-driven business model, with entrepreneurship at the core, is developed with institutional, financing and pricing mechanisms for diffusion of energy services. This approach, termed as EMPOWERS (entrepreneurship model for provision of wholesome energy-related basic services), if adopted, can facilitate large-scale dissemination of energy-efficient and renewable technologies like small-scale biogas/biofuel plants, and distributed power generation technologies to provide clean, safe, reliable and sustainable energy to rural households and urban poor. It is expected to integrate the processes of market transformation and entrepreneurship development involving government, NGOs, financial institutions and community groups as stakeholders.

  12. A national survey of health service infrastructure and policy impacts on access to computerised CBT in Scotland

    Kenicer David

    2012-09-01

    Full Text Available Abstract Background NICE recommends computerised cognitive behavioural therapy (cCBT for the treatment of several mental health problems such as anxiety and depression. cCBT may be one way that services can reduce waiting lists and improve capacity and efficiency. However, there is some doubt about the extent to which the National Health Service (NHS in the UK is embracing this new health technology in practice. This study aimed to investigate Scottish health service infrastructure and policies that promote or impede the implementation of cCBT in the NHS. Methods A telephone survey of lead IT staff at all health board areas across Scotland to systematically enquire about the ability of local IT infrastructure and IT policies to support delivery of cCBT. Results Overall, most of the health boards possess the required software to use cCBT programmes. However, the majority of NHS health boards reported that they lack dedicated computers for patient use, hence access to cCBT at NHS sites is limited. Additionally, local policy in the majority of boards prevent staff from routinely contacting patients via email, skype or instant messenger, making the delivery of short, efficient support sessions difficult. Conclusions Conclusions: Overall most of the infrastructure is in place but is not utilised in ways that allow effective delivery. For cCBT to be successfully delivered within a guided support model, as recommended by national guidelines, dedicated patient computers should be provided to allow access to online interventions. Additionally, policy should allow staff to support patients in convenient ways such as via email or live chat. These measures would increase the likelihood of achieving Scottish health service targets to reduce waiting time for psychological therapies to 18 weeks.

  15. Providing access to risk prediction tools via the HL7 XML-formatted risk web service.

    Chipman, Jonathan; Drohan, Brian; Blackford, Amanda; Parmigiani, Giovanni; Hughes, Kevin; Bosinoff, Phil

    2013-07-01

    Cancer risk prediction tools provide valuable information to clinicians but remain computationally challenging. Many clinics find that CaGene or HughesRiskApps fit their needs for easy- and ready-to-use software to obtain cancer risks; however, these resources may not fit all clinics' needs. The HughesRiskApps Group and BayesMendel Lab therefore developed a web service, called "Risk Service", which may be integrated into any client software to quickly obtain standardized and up-to-date risk predictions for BayesMendel tools (BRCAPRO, MMRpro, PancPRO, and MelaPRO), the Tyrer-Cuzick IBIS Breast Cancer Risk Evaluation Tool, and the Colorectal Cancer Risk Assessment Tool. Software clients that can convert their local structured data into the HL7 XML-formatted family and clinical patient history (Pedigree model) may integrate with the Risk Service. The Risk Service uses Apache Tomcat and Apache Axis2 technologies to provide an all Java web service. The software client sends HL7 XML information containing anonymized family and clinical history to a Dana-Farber Cancer Institute (DFCI) server, where it is parsed, interpreted, and processed by multiple risk tools. The Risk Service then formats the results into an HL7 style message and returns the risk predictions to the originating software client. Upon consent, users may allow DFCI to maintain the data for future research. The Risk Service implementation is exemplified through HughesRiskApps. The Risk Service broadens the availability of valuable, up-to-date cancer risk tools and allows clinics and researchers to integrate risk prediction tools into their own software interface designed for their needs. Each software package can collect risk data using its own interface, and display the results using its own interface, while using a central, up-to-date risk calculator. This allows users to choose from multiple interfaces while always getting the latest risk calculations. Consenting users contribute their data for future

    VoIP, which is used to transmit voice data on the Internet, is being welcomed as a replacement for the PSTN. In VoIP, voice data are converted to IP data and transmitted in an ordinary IP network. As a result, it is less expensive than the ordinary telephone network and has excellent scalability. With the increasing demand for VoIP services, problems are also occurring, namely, security vulnerabilities and degraded service quality. To address these issues, in this paper an AA (Attribute Autho...

  17. Identifying Telemedicine Services to Improve Access to Specialty Care for the Underserved in the San Francisco Safety Net

    Ken Russell Coelho

    2011-01-01

    Full Text Available Safety-net settings across the country have grappled with providing adequate access to specialty care services. San Francisco General Hospital and Trauma Center, serving as the city's primary safety-net hospital, has also had to struggle with the same issue. With Healthy San Francisco, the City and County of San Francisco's Universal Healthcare mandate, the increased demand for specialty care services has placed a further strain on the system. With the recent passage of California Proposition 1D, infrastructural funds are now set aside to assist in connecting major hospitals with primary care clinics in remote areas all over the state of California, using telemedicine. Based on a selected sample of key informant interviews with local staff physicians, this study provides further insight into the current process of e-referral which uses electronic communication for making referrals to specialty care. It also identifies key services for telemedicine in primary and specialty care settings within the San Francisco public health system. This study concludes with proposals for a framework that seek to increase collaboration between the referring primary care physician and specialist, to prioritize institution of these key services for telemedicine.

  1. Design of a High Resolution Open Access Global Snow Cover Web Map Service Using Ground and Satellite Observations

    Kadlec, J.; Ames, D. P.

    2014-12-01

    The aim of the presented work is creating a freely accessible, dynamic and re-usable snow cover map of the world by combining snow extent and snow depth datasets from multiple sources. The examined data sources are: remote sensing datasets (MODIS, CryoLand), weather forecasting model outputs (OpenWeatherMap, forecast.io), ground observation networks (CUAHSI HIS, GSOD, GHCN, and selected national networks), and user-contributed snow reports on social networks (cross-country and backcountry skiing trip reports). For adding each type of dataset, an interface and an adapter is created. Each adapter supports queries by area, time range, or combination of area and time range. The combined dataset is published as an online snow cover mapping service. This web service lowers the learning curve that is required to view, access, and analyze snow depth maps and snow time-series. All data published by this service are licensed as open data; encouraging the re-use of the data in customized applications in climatology, hydrology, sports and other disciplines. The initial version of the interactive snow map is on the website snow.hydrodata.org. This website supports the view by time and view by site. In view by time, the spatial distribution of snow for a selected area and time period is shown. In view by site, the time-series charts of snow depth at a selected location is displayed. All snow extent and snow depth map layers and time series are accessible and discoverable through internationally approved protocols including WMS, WFS, WCS, WaterOneFlow and WaterML. Therefore they can also be easily added to GIS software or 3rd-party web map applications. The central hypothesis driving this research is that the integration of user contributed data and/or social-network derived snow data together with other open access data sources will result in more accurate and higher resolution - and hence more useful snow cover maps than satellite data or government agency produced data by

  2. “We don’t need services. We have no problems”: exploring the experiences of young people who inject drugs in accessing harm reduction services

    Anita Krug

    2015-02-01

    Full Text Available Introduction: Evidence suggests that people who inject drugs often begin their drug use and injecting practices in adolescence, yet there are limited data available on the HIV epidemic and the responses for this population. The comprehensive package of interventions for the prevention, treatment and care of HIV infection among people who inject drugs first laid out in 2009 (revised in 2012 by World Health Organization, United Nations Office of Drugs and Crime and Joint United Nations Programme on HIV/AIDS, does not consider the unique needs of adolescent and young people. In order to better understand the values and preferences of young people who inject drugs in accessing harm reduction services and support, we undertook a series of community consultations with young people with experience of injecting drugs during adolescence. Methods: Community consultations (4–14 persons were held in 14 countries. Participants were recruited using a combined criterion and maximum variation sampling strategy. Data were analyzed using collaborative qualitative data analysis. Frequency analysis of themes was conducted. Results: Nineteen community consultations were organized with a total of 132 participants. All participants had experienced injecting drugs before the age of 18. They had the following age distribution: 18–20 (37%, 21–25 (48% and 26–30 (15%. Of the participants, 73.5% were male while 25.7% were female, with one transgender participant. Barriers to accessing the comprehensive package included: lack of information and knowledge of services, age restrictions on services, belief that services were not needed, fear of law enforcement, fear of stigma, lack of concern, high cost, lack of outreach, lack of knowledge of HCV/TB and lack of youth friendly services. Conclusions: The consultations provide a rare insight into the lived experiences of adolescents who inject drugs and highlight the dissonance between their reality and current policy and

    2011-12-01

    Insufficiently integrated data management and access systems are a major problem that data managers, scientists and users encounter when trying to serve, locate or use climate data. A fragmented approach to data management has promoted individualized solutions, often resulting in the creation of non-interoperable data formats and protocols. The NOAA-led Unified Access Framework (UAF) project has endeavored to define a framework for data providers wishing to share their data in a more interoperable manner. Using standards and conventions that are already widely used and embraced by the community, such interoperable data solutions can be quickly and easily configured and made available to the public. Though gazing through this optimistic interoperability lens, we do realize that there are still limitations within the data community that must be faced. In fact, the solutions that we plan to demonstrate are only really mature for gridded datasets. As well, there are many outstanding issues dealing with immature metadata (including lack of detailed model configurations and data provenance information) which must be overcome for true interoperability. In this presentation, however, we will be demonstrating that, by embracing open standards and conventions and community supported resources, it is possible to have an interoperable data service for gridded data up and running in less than 15 minutes. Following the storyline of a modeler who has data s/he wants to share immediately, we'll demonstrate how to serve the data using OPeNDAP and THREDDS. We'll also exhibit how to easily improve the data in order to increase interoperability, without modification to the original dataset. These improvements will include techniques for data aggregation and also methods to ensure compliance with known conventions, such as the Climate and Forecast (CF) metadata conventions. The presentation will culminate with a discussion and demonstration of a few of the many available and widely

  5. Poverty, food security and universal access to sexual and reproductive health services: a call for cross-movement advocacy against neoliberal globalisation.

    Sundari Ravindran, T K

    2014-05-01

    Universal access to sexual and reproductive health services is one of the goals of the International Conference on Population and Development of 1994. The Millennium Development Goals were intended above all to end poverty. Universal access to health and health services are among the goals being considered for the post-2015 agenda, replacing or augmenting the MDGs. Yet we are not only far from reaching any of these goals but also appear to have lost our way somewhere along the line. Poverty and lack of food security have, through their multiple linkages to health and access to health care, deterred progress towards universal access to health services, including for sexual and reproductive health needs. A more insidious influence is neoliberal globalisation. This paper describes neoliberal globalisation and the economic policies it has engendered, the ways in which it influences poverty and food security, and the often unequal impact it has had on women as compared to men. It explores the effects of neoliberal economic policies on health, health systems, and universal access to health care services, and the implications for access to sexual and reproductive health. To be an advocate for universal access to health and health care is to become an advocate against neoliberal globalisation. PMID:24908453

    Full Text Available Digital forensics tools have many potential applications in the curation of digital materials in libraries, archives and museums (LAMs. Open source digital forensics tools can help LAM professionals to extract digital contents from born-digital media and make more informed preservation decisions. Many of these tools have ways to display the metadata of the digital media, but few provide file-level access without having to mount the device or use complex command-line utilities. This paper describes a project to develop software that supports access to the contents of digital media without having to mount or download the entire image. The work examines two approaches in creating this tool: First, a graphical user interface running on a local machine. Second, a web-based application running in web browser. The project incorporates existing open source forensics tools and libraries including The Sleuth Kit and libewf along with the Flask web application framework and custom Python scripts to generate web pages supporting disk image browsing.

  7. Access to serviced land for the urban poor: the regularization paradox in Mexico

    2000-01-01

    Full Text Available The insufficient supply of serviced land at affordable prices for the urban poor and the need for regularization of the consequent illegal occupations in urban areas are two of the most important issues on the Latin American land policy agenda. Taking a structural/integrated view on the functioning of the urban land market in Latin America, this paper discusses the nexus between the formal and the informal land markets. It thus exposes the perverse feedback effects that curative regularization policies may have on the process by which irregularity is produced in the first place. The paper suggests that a more effective approach to the provision of serviced land for the poor cannot be resolved within the prevailing (curative regularization programs. These programs should have the capacity to mobilize the resources that do exist into a comprehensive program that links regularization with fiscal policy, including the exploration of value capture mechanisms.

  8. Access to physician services: does supplemental insurance matter? evidence from France.

    In France, public health insurance is universal but incomplete, with private payments accounting for roughly 25% of all spending. As a result, most people have supplemental private health insurance. We investigate the effects of such insurance on the utilization of physician services using data from the 1998 Enquête sur la santé et la protection sociale, a nationally representative survey of the non-institutionalized French population. Our results indicate that insurance has a strong and significant effect on the utilization of physician services. Individuals with supplemental coverage have substantially more physician visits than those without. While French patients have greater freedom than patients in other countries to choose to see a specialist rather than a general practitioner, we find no evidence that supplemental insurance affects this decision.

  9. Consumer adoption of access-based consumption services - Case AirBnB

    Satama, Sampo

    2014-01-01

    Increasing internet and smart phone penetration has given rise to a new business model, in which the service companies act as intermediaries and allow consumers to exchange value between them. Usually this is done by facilitating resource exchange between the consumers - one party that needs a resource such as a car, a designer bag or a place to stay rents or shares this resource with another party that has no need for the resource at the moment. This phenomenon has been dubbed collaborati...

  10. Some issues on provision and access to dental services in Norway

    Abelsen, Birgit

    2009-01-01

    The organisation and financing of the Norwegian oral health care differ compared to general health care. The public responsibility for general health care includes the whole population, and the scope is universal coverage involving public finance, and historically public provision as well. Concerning oral health care, there seems to be less emphasis on providing the same level of service to all citizens. The limited public responsibility for providing oral health care leaves Norwegian dentist...

    Full Text Available This paper evaluates the performance of sending Triple play Services over hybrid networks. The network performance factors will be considered by observing the network`s availability, packet loss, delay and throughput. These evaluations will be tested over different network scenario, where the last mile media services suggested to be delivered over telephone twisted pair by means of using ADSL. The attention will be concerned for services over cable, where a proposal of using bandwidth efficient turbo trellis coded modulation (TTCM in ADSL DMT systems instead of the multidimensional 16-state Trellis Coded Modulation (MTCM that is given as an option in Asymmetric Digital Subscriber Lines (ADSL standard based on discrete multitone (DMT techniques. The results show that by using turbo codes, it can obtain 6 dB coding gain for a bit error rate (BER of 10-6 in AWGN channels and more than 6.8 dB coding gain for a BER of 10-7 using a concatenated coding scheme.

  14. A nutrition strategy to reduce the burden of diet related disease: access to dietician services must complement population health approaches.

    Segal, Leonie; Opie, Rachelle S

    2015-01-01

    Poor diet quality is implicated in almost every disease and health issue. And yet, in most advanced market economies diet quality is poor, with a minority meeting guidelines for healthy eating. Poor diet is thus responsible for substantial disease burden. Societies have at their disposal a range of strategies to influence diet behaviors. These can be classified into: (i) population level socio-educational approaches to enhance diet knowledge; (ii) pricing incentives (subsidies on healthy foods, punitive taxes on unhealthy foods); (iii) regulations to modify the food environment, and (iv) the provision of clinical dietetic services. There is little evidence that societies are active in implementing the available strategies. Advertising of "junk foods" is largely unchecked, contrasting with strict controls on advertising tobacco products, which also attract punitive taxes. Access to dieticians is restricted in most countries, even in the context of universal health care. In Australia in 2011 there were just 2,969 practicing dieticians/nutritionists or 1.3 clinicians per 10,000 persons, compared with 5.8 physiotherapists per 10,000 persons, 14.8 general practitioners (family physicians) per 10,000 persons or 75 nurses per 10,000 persons. It is time to implement comprehensive national nutrition strategies capable of effecting change. Such strategies need to be multi-component, incorporating both public health approaches and expanded publicly funded dietetic services. Access to individualized dietetic services is needed by those at risk, or with current chronic conditions, given the complexity of the diet message, the need for professional support for behavior change and to reflect individual circumstances. The adoption of a comprehensive nutrition strategy offers the promise of substantial improvement in diet quality, better health and wellbeing and lower health care costs. PMID:26321951

    Full Text Available Abstract Background Family and pregnancy planning issues are important among human immunodeficiency virus (HIV-positive individuals and couples. However, access to fertility services may be limited for this population. The objective of this study was to estimate the types of services available in fertility clinics in Canada for these individuals. Methods A survey was sent to all registered fertility clinics in Canada to assess the availability of services (investigations and treatment for infertility and/or viral transmission risk reduction in achieving pregnancy. The proportion and location of clinics willing to carry out investigations and treatments were determined. Logistic regression analysis was performed to assess differences in response rates, investigations, and treatments by province and by couple scenario. Results Completed surveys were received from 23/28 (82% of clinics across eight Canadian provinces. Seventy-eight per cent (18/23 were willing to accept HIV-positive individuals in consultation, and 52% had actually seen at least one HIV-positive man or woman in the previous year. Clinics in every province were willing to offer infertility investigations, but only clinics located in five provinces were willing to offer fertility treatments. The most commonly available treatment was intrauterine insemination for couples in which the female partner was HIV-positive (52%. Other techniques, such as sperm washing (26% or in vitro fertilization (17%, were less commonly offered. A smaller number of clinics were willing to offer risk reduction techniques in achieving pregnancy. Conclusions Access to infertility investigations and treatments in Canada is limited and regionally dependent. Trial Registration Registered with ClinicalTrials.gov at http://www.clinicaltrials.gov, registration number NCT00782132.

  16. Improving access to competitive employment for service users in forensic psychiatric units

    Beck, Charlotte; Wernham, Connie

    2014-01-01

    Employment has been proven to be an effective recovery tool and therapeutic intervention for those with severe and enduring mental health conditions. Aside from monetary reward, employment is a means of structuring time and provides a sense of worth and achievement, which enhances self-esteem and confidence. A social identity is developed through employment, encouraging social support and increasing social networks. Securing employment can bring about improved quality of life and positive change in one's social circumstances; therefore it can reduce symptoms associated with mental illness and potentially prevent re-offending, as the individual develops a sense of independence, self-efficacy, and value. Barriers to employment exist for forensic mental health service users and therefore it is imperative that employment needs are addressed at the earliest possible stage in recovery. An evaluation of employment activities across two forensic mental health units revealed a lack of appropriate employment opportunities for service users, and those roles available were not implemented in line with recommended best practice. In response to this issue several enterprises were established to offer opportunities for service users to engage in meaningful employment and develop skills that a future employer would value. Each enterprise responds to a business need within the units to ensure sustainability of services. The enterprises are essentially micro-businesses with social objectives whose surpluses are reinvested for the purpose of increasing opportunities for service users. The enterprises are underpinned by the philosophy of the Individual Placement and Support (IPS) model; empirical evidence suggests that the IPS model is the most effective intervention, based on the ‘place then train’ philosophy. The model recommends a focus upon rapid job search to achieve competitive employment for those who want to work; opportunities sourced should be consistent with individual

    Background: The measurement of consumer satisfaction is an essential part of the assessment of health care services in terms of service quality and health care system responsiveness. Studies across Europe have described various strategies health care users employ to secure services with good quality and quick access. In Central and Eastern European countries, such strategies also include informal payments to health care providers. This paper analyzes the satisfaction of health care users with...

  20. Mapping socio-environmentally vulnerable populations access and exposure to ecosystem services at the U.S.-Mexico borderlands

    Socio-environmental vulnerable populations are often unrepresented in land-use planning yet have great potential for loss when exposed to changes in ecosystem services. Administrative boundaries, cultural differences, and language barriers increase the disassociation between land-use management and marginalized populations living in the U.S.–Mexico borderlands. This paper describes the development of a Modified Socio-Environmental Vulnerability Index (M-SEVI), using determinants from binational census and neighborhood data that describe levels of education, access to resources, migratory status, housing, and number of dependents, to provide a simplified snapshot of the region's populace that can be used in binational planning efforts. We apply this index at the SCW, located on the border between Arizona, USA and Sonora, Mexico. For comparison, the Soil and Water Assessment Tool is concurrently applied to assess the provision of erosion- and flood control services over a 9-year period. We describe how this coupling of data can form the base for an ecosystem services assessment across political boundaries that can be used by land-use planners. Results reveal potential disparities in environmental risks and burdens throughout the binational watershed in residential districts surrounding and between urban centers. The M-SEVI can be used as an important first step in addressing environmental justice for binational decision-making.
