    Introduction The concept of patient-centred care (PCC) is changing the way healthcare is understood, accepted and delivered. The Institute of Medicine has defined PCC as 1 of its 6 aims to improve healthcare quality. However, in Canada, there are currently no nationwide standards in place for measuring and evaluating healthcare from a patient-centred approach. In this paper, we outline our scoping review protocol to systematically review published and unpublished literature specific to patient-centred quality indicators that have been implemented and evaluated across various care settings. Methods and analysis Arksey and O'Malley's scoping review methodology framework will guide the conduct of this scoping review. We will search electronic databases (MEDLINE, EMBASE, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Social Work Abstracts, Social Services Abstracts), grey literature sources and the reference lists of key studies to identify studies appropriate for inclusion. 2 reviewers will independently screen all abstracts and full-text studies for inclusion. We will include any study which focuses on quality indicators in the context of PCC. All bibliographic data, study characteristics and indicators will be collected and analysed using a tool developed through an iterative process by the research team. Indicators will be classified according to a predefined conceptual framework and categorised and described using qualitative content analysis. Ethics and dissemination The scoping review will synthesise patient-centred quality indicators and their characteristics as described in the literature. This review will be the first step to formally identify what quality indicators have been used to evaluate PCC across the healthcare continuum, and will be used to inform a stakeholder consensus process exploring the development of a generic set of patient-centred quality indicators applicable to multiple care settings.

    Full Text Available INTRODUCTION: The application of health economic evaluation (HEE evidence can play an important role in strategic planning and policy making. This study aimed to assess the scope and quality of existing research, with the goal of elucidating implications for improving the use of HEE evidence in Vietnam. METHODS: A comprehensive search strategy was developed to search medical online databases (Medline, Google Scholar, and Vietnam Medical Databases to select all types of HEE studies except cost-only analyses. Two researchers assessed the quality of selected studies using the Quality of Health Economic Studies (QHES instrument. RESULTS: We selected 26 studies, including 6 published in Vietnam. The majority of these studies focused on infectious diseases (14 studies, with HIV being the most common topic (5 studies. Most papers were cost-effectiveness studies that measured health outcomes using DALY units. Using QHES, we found that the overall quality of HEE studies published internationally was much higher (mean score 88.7+13.3 than that of those published in Vietnam (mean score 67.3+22.9. Lack of costing perspectives, reliable data sources and sensitivity analysis were the main shortcomings of the reviewed studies. CONCLUSION: This review indicates that HEE studies published in Vietnam are limited in scope and number, as well as by several important technical errors or omissions. It is necessary to formalize the process of health economic research in Vietnam and to institutionalize the links between researchers and policy-makers. Additionally, the quality of HEE should be enhanced through education about research techniques, and the implementation of standard HEE guidelines.

    The Desert Research Institute (DRI) is performing a scoping study as part of the U.S.Department of Energy’s Yucca Mountain Environmental Monitoring Systems Initiative (EMSI). The main objective is to obtain baseline air quality information for Yucca Mountain and an area surrounding the Nevada Test Site (NTS). Air quality and meteorological monitoring and sampling equipment housed in a mobile trailer (shelter) is collecting data at seven sites outside the NTS, including Ash Meadows National Wildlife Refuge, Sarcobatus Flat, Beatty, Rachel, Caliente, Pahranagat National Wildlife Refuge, and Crater Flat, and at four sites on the NTS. The trailer is stationed at any one site for approximately eight weeks at a time. Letter reports provide summaries of air quality and meteorological data, on completion of each site’s sampling program.

    Assessments of methodological and reporting quality are critical to adequately judging the credibility of a study's conclusions and to gauging its potential reproducibility. To aid those seeking to assess the methodological or reporting quality of studies relevant to toxicology, we conducted a scoping review of the available guidance with respect to four types of studies: in vivo and in vitro, (quantitative) structure-activity relationships ([Q]SARs), physico-chemical, and human observational studies. Our aims were to identify the available guidance in this diverse literature, briefly summarize each document, and distill the common elements of these documents for each study type. In general, we found considerable guidance for in vivo and human studies, but only one paper addressed in vitro studies exclusively. The guidance for (Q)SAR studies and physico-chemical studies was scant but authoritative. There was substantial overlap across guidance documents in the proposed criteria for both methodological and reporting quality. Some guidance documents address toxicology research directly, whereas others address preclinical research generally or clinical research and therefore may not be fully applicable to the toxicology context without some translation. Another challenge is the degree to which assessments of methodological quality in toxicology should focus on risk of bias - as in clinical medicine and healthcare - or be broadened to include other quality measures, such as confirming the identity of test substances prior to exposure. Our review is intended primarily for those in toxicology and risk assessment seeking an entry point into the extensive and diverse literature on methodological and reporting quality applicable to their work.

    The Los Alamos National Laboratory – Carlsbad Operations (LANL-CO) office was tasked by the DOE CBFO, Office of the Manager to: • Perform a review of the acceptable knowledge (AK) to identify the oxidizers and sorbents in transuranic (TRU) waste streams. • Conduct scoping studies on the oxidizers and sorbents identified in AK review to inform the Quality Level 1 (QL1) testing. • Conduct a series of QL1 tests to provide the scientific data to support a basis of knowledge document for determining the criteria for: 1) accepting waste at the Waste Isolation Pilot Plant (WIPP) without treatment, 2) determining waste that will require treatment, and 3) if treatment is required, how the treatment must be performed. The purpose of this report is to present the results of the AK review of sorbents present in active waste streams, provide a technical analysis of the sorbent list, report the results of the scoping studies for the fastest burning organic sorbent, and provide the list of organic and inorganic sorbents to be used in the development of a Test Plan for Preparation and Testing of Sorbents Mixed with Oxidizer found in Transuranic Waste (DWT-TP-001). The companion report, DWT-RPT-001, Oxidizer Scoping Studies, has similar information for oxidizers identified during the AK review of TRU waste streams. The results of the oxidizer and sorbent scoping studies will be used to inform the QL1 test plan. The QL1 test results will support the development of a basis of knowledge document that will evaluate oxidizing chemicals and sorbents in TRU waste and provide guidance for treatment.

    Full Text Available Abstract Background Scoping studies are an increasingly popular approach to reviewing health research evidence. In 2005, Arksey and O'Malley published the first methodological framework for conducting scoping studies. While this framework provides an excellent foundation for scoping study methodology, further clarifying and enhancing this framework will help support the consistency with which authors undertake and report scoping studies and may encourage researchers and clinicians to engage in this process. Discussion We build upon our experiences conducting three scoping studies using the Arksey and O'Malley methodology to propose recommendations that clarify and enhance each stage of the framework. Recommendations include: clarifying and linking the purpose and research question (stage one; balancing feasibility with breadth and comprehensiveness of the scoping process (stage two; using an iterative team approach to selecting studies (stage three and extracting data (stage four; incorporating a numerical summary and qualitative thematic analysis, reporting results, and considering the implications of study findings to policy, practice, or research (stage five; and incorporating consultation with stakeholders as a required knowledge translation component of scoping study methodology (stage six. Lastly, we propose additional considerations for scoping study methodology in order to support the advancement, application and relevance of scoping studies in health research. Summary Specific recommendations to clarify and enhance this methodology are outlined for each stage of the Arksey and O'Malley framework. Continued debate and development about scoping study methodology will help to maximize the usefulness and rigor of scoping study findings within healthcare research and practice.

    Much like individual microgrids, the range of opportunities and potential architectures of networked microgrids is very diverse. The goals of this scoping study are to provide an early assessment of research and development needs by examining the benefits of, risks created by, and risks to networked microgrids. At this time there are very few, if any, examples of deployed microgrid networks. In addition, there are very few tools to simulate or otherwise analyze the behavior of networked microgrids. In this setting, it is very difficult to evaluate networked microgrids systematically or quantitatively. At this early stage, this study is relying on inputs, estimations, and literature reviews by subject matter experts who are engaged in individual microgrid research and development projects, i.e., the authors of this study The initial step of the study gathered input about the potential opportunities provided by networked microgrids from these subject matter experts. These opportunities were divided between the subject matter experts for further review. Part 2 of this study is comprised of these reviews. Part 1 of this study is a summary of the benefits and risks identified in the reviews in Part 2 and synthesis of the research needs required to enable networked microgrids.

    The goals of this scoping study are to identify research needed to develop improved ventilation standards for California's Title 24 Building Energy Efficiency Standards. The 2008 Title 24 Standards are the primary target for the outcome of this research, but this scoping study is not limited to that timeframe. We prepared this scoping study to provide the California Energy Commission with broad and flexible options for developing a research plan to advance the standards. This document presents the findings of a scoping study commissioned by the Public Interest Energy Research (PIER) program of the California Energy Commission to determine what research is necessary to develop new residential ventilation requirements for California. This study is one of three companion efforts needed to complete the job of determining the ventilation needs of California residences, determining the bases for setting residential ventilation requirements, and determining appropriate ventilation technologies to meet these needs and requirements in an energy efficient manner. Rather than providing research results, this scoping study identifies important research questions along with the level of effort necessary to address these questions and the costs, risks, and benefits of pursuing alternative research questions. In approaching these questions and corresponding levels of effort, feasibility and timing were important considerations. The Commission has specified Summer 2005 as the latest date for completing this research in time to update the 2008 version of California's Energy Code (Title 24).

    While the utilization of a microgrid for local power reliability during grid outage and emergencies is a well-known benefit, the integration of microgrids with the broader electrical distribution system will allow for seamless interaction with distribution system operations, contributing to resource and economic optimization, enhanced reliability and resiliency, and improved power quality. By virtue of integration with the distribution system, multiple microgrids should be networked and collectively known as networked microgrids. As a follow-up to the work conducted by Oak Ridge National Laboratory on a microgrid controller [the Complete System-level Efficient and Interoperable Solution for Microgrid Integrated Controls (CSEISMIC)], the main goal of this work is to identify the next steps for bringing microgrid research to the utility industry, particularly as a resource for enhancing efficiency, reliability, and resilience. Various R&D needs for the integration of microgrids into the distribution system have been proposed, including interconnection types, communications, control architectures, quantification of benefits, functional requirements, and various operational issues.

  15. A scoping study on the costs of indoor air quality illnesses:an insurance loss reduction perspective

    The incidence of commercial buildings with poor indoor air quality (IAQ), and the frequency of litigation over the effects of poor IAQ is increasing. If so, these increases have ramifications for insurance carriers, which pay for many of the costs of health care and general commercial liability. However, little is known about the actual costs to insurance companies from poor IAQ in buildings. This paper reports on the results of a literature search of buildings-related, business and legal databases, and interviews with insurance and risk management representatives aimed at finding information on the direct costs to the insurance industry of poor building IAQ, as well as the costs of litigation. The literature search and discussions with insurance and risk management professionals reported in this paper turned up little specific information about the costs of IAQ-related problems to insurance companies. However, those discussions and certain articles in the insurance industry press indicate that there is a strong awareness and growing concern over the "silent crisis" of IAQ and its potential to cause large industry losses, and that a few companies are taking steps to address this issue. The source of these losses include both direct costs to insurers from paying health insurance and professional liability claims, as weIl as the cost of litigation. In spite of the lack of data on how IAQ-related health problems affect their business, the insurance industry has taken the anecdotal evidence about their reality seriously enough to alter their policies in ways that have lessened their exposure. We conclude by briefly discussing four activities that need to be addressed in the near future: (1) quantifying IAQ-related insurance costs by sector, (2) educating the insurance industry about the importance of IAQ issues, (3) examining IAQ impacts on the insurance industry in the residential sector, and (4) evaluating the relationship between IAQ improvements and their impact on

    A scoping study for a Tokamak Engineering Technology Facility (TETF) is presented. The TETF is a tokamak with R = 3 m and I/sub p/ = 1.4 MA based on the counterstreaming-ion torus mode of operation. The primary purpose of TETF is to demonstrate fusion technologies for the Experimental Power Reactor (EPR), but it will also serve as an engineering and radiation test facility. TETF has several technological systems (e.g., superconducting toroidal-field coil, tritium fuel cycle, impurity control, first wall) that are prototypical of EPR.

    Full Text Available Abstract Background The purpose of this study was to conduct a scoping review of the literature about the establishment and impact of quality and safety team initiatives in acute care. Methods Studies were identified through electronic searches of Medline, Embase, CINAHL, PsycINFO, ABI Inform, Cochrane databases. Grey literature and bibliographies were also searched. Qualitative or quantitative studies that occurred in acute care, describing how quality and safety teams were established or implemented, the impact of teams, or the barriers and/or facilitators of teams were included. Two reviewers independently extracted data on study design, sample, interventions, and outcomes. Quality assessment of full text articles was done independently by two reviewers. Studies were categorized according to dimensions of quality. Results Of 6,674 articles identified, 99 were included in the study. The heterogeneity of studies and results reported precluded quantitative data analyses. Findings revealed limited information about attributes of successful and unsuccessful team initiatives, barriers and facilitators to team initiatives, unique or combined contribution of selected interventions, or how to effectively establish these teams. Conclusions Not unlike systematic reviews of quality improvement collaboratives, this broad review revealed that while teams reported a number of positive results, there are many methodological issues. This study is unique in utilizing traditional quality assessment and more novel methods of quality assessment and reporting of results (SQUIRE to appraise studies. Rigorous design, evaluation, and reporting of quality and safety team initiatives are required.

    2011-06-01

    Full Text Available Software quality is a composite work and can be enriched by high level analysis, design structure, encoding, testing to be followed with a properly structured FTR and corrective action. This has become a conventional practice. New voices are being heard that quality principles can be factored into a model and that can turn out abroad spectrum of indices and metrics. In turn these indices and metrics can measure either explicitly or implicitly the quality of the software. Variations in turning out finely designed product eat into the vitals of quality content. Control over quality is ensured by setting in motion a chain of inspections reviews and tests thatverify that each section of the working module functionally meets its assigned task. Where deviations from the norms specified are observed the aberrations are to be corrected by retuning the process. Quality Assurance is possible only if quality products are turned out. In turn it is helped by auditing and reporting. Needless to saymere auditing and reporting will not produce quality products.

    1998-02-01

    A Settlement Agreement between the Department of Energy (DOE) and the State of Idaho mandates that all high-level radioactive waste (HLW) now stored at the Idaho Chemical Processing Plant (ICPP) on the Idaho National Engineering and Environmental Laboratory (INEEL) will be treated so that it is ready to be moved out of Idaho for disposal by a target date of 2035. This study investigates the nonseparations Cementitious Waste Option (CWO) as a means to achieve this goal. Under this option all liquid sodium-bearing waste (SBW) and existing HLW calcine would be recalcined with sucrose, grouted, canisterized, and interim stored as a mixed-HLW for eventual preparation and shipment off-Site for disposal. The CWO waste would be transported to a Greater Confinement Disposal Facility (GCDF) located in the southwestern desert of the US on the Nevada Test Site (NTS). All transport preparation, shipment, and disposal facility activities are beyond the scope of this study. CWO waste processing, packaging, and interim storage would occur over a 5-year period between 2013 and 2017. Waste transport and disposal would occur during the same time period.

    This study aimed to examine and map the scientific evidences regarding quality of life in neurogenic bladder patients and consequently their caregivers by means of a scoping review. This is a scoping review proposal of the Joanna Briggs Institute. It was conducted to examine and map the scientific evidences about quality of life (QoL) in neurogenic bladder patients and their caregivers, to identify the meanings attributed to QoL and its relation with intermittent urinary catheterization. The following guiding question was: "What scientific evidence has been produced on the QoL of neurogenic bladder patients using intermittent urinary catheterization and their caregivers?" A total of 2945 research studies were identified using The Cochrane Library, CINAHL, LILACS, Academic Search Premier (via EBSCO platform), PubMed, SCOPUS, the platforms Web of Science, the b-on and Gray Literature. The keywords established were patient, intermittent urinary catheterization, neurogenic urinary bladder, quality of life and caregiver. From 2,945 studies, 13 studies were selected. Most of the selected studies that analyzed variables related to the patients' QoL were regarding the urinary catheterization technique, assessment of urinary incontinence, individual perceptions of the procedure and experiences with urinary catheter in childhood and adult life. The meanings attributed to QoL, when compared to adult and child individuals with normal bladder functioning, presented lower QoL scores. Concerning caregivers, the QoL of caregivers of children using intermittent urinary catheterization demonstrated low scores. The QoL of patient's who use intermittent urinary catheterization can be determined by improvement of urinary symptoms and self-confidence. Research related to QoL of patients who use urinary catheter indicates the importance of adequate professional support and appropriate health public policies. © 2017 Sigma Theta Tau International.

    Asynchronous telehealth captures clinically important digital samples (e.g., still images, video, audio, text files) and relevant data in one location and subsequently transmits these files for interpretation at a remote site by health professionals without requiring the simultaneous presence of the patient involved and his or her health care provider. Its utility in the health care system, however, still remains poorly defined. We conducted this scoping review to determine the impact of asynchronous telehealth on health outcomes, process of care, access to health services, and health resources. A search was performed up to December 2006 of MEDLINE, CINAHL, HealthSTAR, the Database of Abstracts of Reviews of Effectiveness, and The Cochrane Library. Studies were included if they contained original data on the use of asynchronous telehealth and were published in English in a peer-reviewed journal. Two independent reviewers screened all articles and extracted data, reaching consensus on the articles and data identified. Data were extracted on general study characteristics, clinical domain, technology, setting, category of outcome, and results. Study quality (internal validity) was assessed using the Jadad scale for randomized controlled trials and the Downs and Black index for non-randomized studies. Summary data were categorized by medical specialty and presented qualitatively. The scoping review included 52 original studies from 238 citations identified; of these 52, almost half focused on the use of telehealth in dermatology. Included studies were characterized by diverse designs, interventions, and outcomes. Only 16 studies were judged to be of high quality. Most studies showed beneficial effects in terms of diagnostic accuracy, wait times, referral management, and satisfaction with services. Evidence on the impact of asynchronous telehealth on resource use in dermatology suggests a reduction in the number of, or avoidance of, in-person visits. Reports from other

    Full Text Available Background. Among circumpolar populations, recent research has documented a significant increase in risk factors which are commonly associated with chronic disease, notably obesity. Objective. The present study undertakes a scoping review of research on obesity in the circumpolar Inuit to determine the extent obesity research has been undertaken, how well all subpopulations and geographic areas are represented, the methodologies used and whether they are sufficient in describing risk factors, and the prevalence and health outcomes associated with obesity. Design. Online databases were used to identify papers published 1992–2011, from which we selected 38 publications from Canada, the United States, and Greenland that used obesity as a primary or secondary outcome variable in 30 or more non-pregnant Inuit (“Eskimo” participants aged 2 years or older. Results. The majority of publications (92% reported cross-sectional studies while 8% examined retrospective cohorts. All but one of the studies collected measured data. Overall 84% of the publications examined obesity in adults. Those examining obesity in children focused on early childhood or adolescence. While most (66% reported 1 or more anthropometric indices, none incorporated direct measures of adiposity. Evaluated using a customized quality assessment instrument, 26% of studies achieved an “A” quality ranking, while 18 and 39% achieved quality rankings of “B” and “C”, respectively. Conclusions. While the quality of studies is generally high, research on obesity among Inuit would benefit from careful selection of methods and reference standards, direct measures of adiposity in adults and children, studies of preadolescent children, and prospective cohort studies linking early childhood exposures with obesity outcomes throughout childhood and adolescence.

    Data quality is an important issue when managing food composition data since the usage of the data can have a significant influence on policy making and further research. Although several frameworks for data quality have been proposed, general tools and measures are still lacking. As a first step in this direction, we investigated data quality requirements for an information system to manage food composition data, called FoodCASE. The objective of our investigation was to find out if different requirements have different impacts on the intrinsic data quality that must be regarded during data quality assessment and how these impacts can be described.

    Education and training in prosthetics and orthotics typically comply with International Society for Prosthetics and Orthotics standards based on three categories of prosthetic and orthotic professionals. This scoping study sought to describe the evidence base available to answer the question, How are prosthetic and orthotic services influenced by the training of staff providing them? Scoping review. A structured search of the peer-reviewed literature catalogued in major electronic databases yielded 3039 papers. Following review of title and abstract, 93 articles were considered relevant. Full-text review reduced this number to 25. Only two articles were identified as providing direct evidence of the effects of training and education on service provision. While both suggested that there was an impact, it is difficult to see how the more specific conclusions of either could be generalised. The other 23 articles provide a useful background to a range of issues including the specification of competencies that training programmes should deliver (3 articles), descriptions of a range of training programmes and the effects of training and education on student knowledge and skills. Although it is considered axiomatic, the service quality is dependent on practitioner education and training. There is insufficient evidence to establish whether levels of training and education in prosthetics and orthotics have an effect on the quality of prosthetic and orthotic services. Clinical relevance There is very little evidence about the effects of training and education of prosthetists and orthotists on service quality. While this is a somewhat negative finding, we feel that it is important to bring this to the attention of the prosthetics and orthotics community.

    Background To date there is no established consensus of assessment criteria for evaluating research ethics review. Methods We conducted a scoping review of empirical research assessing ethics review processes in order to identify common elements assessed, research foci, and research gaps to aid in the development of assessment criteria. Electronic searches of Ovid Medline, PsychInfo, and the Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED, were conducted. After de-duplication, 4234 titles and abstracts were reviewed. Altogether 4036 articles were excluded following screening of titles, abstracts and full text. A total of 198 articles included for final data extraction. Results Few studies originated from outside North America and Europe. No study reported using an underlying theory or framework of quality/effectiveness to guide study design or analyses. We did not identify any studies that had involved a controlled trial - randomised or otherwise – of ethics review procedures or processes. Studies varied substantially with respect to outcomes assessed, although tended to focus on structure and timeliness of ethics review. Discussion Our findings indicate a lack of consensus on appropriate assessment criteria, exemplified by the varied study outcomes identified, but also a fragmented body of research. To date research has been largely quantitative, with little attention given to stakeholder experiences, and is largely cross sectional. A lack of longitudinal research to date precludes analyses of change or assessment of quality improvement in ethics review. PMID:26225553

    The continuous and exact recording of infections is a condition sine qua non for total quality management. Therefore, at the Diakoniekrankenhaus Rotenburg (Wümme) a program which offers the possibility of online recording of data was integrated into the hospital intranet. The recording is done with network clients. The recording of data is supported by a series of plausibility controls. The advantage consists in immediate evaluation of up to date and extensive statistics of infections. By integration into the existing system, relevant influences and consequences such as the prolongation of hospitalisation, use of material, and frequency of reoperation can by recognized and immediately considered with high validity.

  12. Oak Ridge Tokamak experimental power reactor study scoping report

    1977-03-01

    This report presents the scoping studies performed as the initial part of the program to produce a conceptual design for a Tokamak Experimental Power Reactor (EPR). The EPR as considered in this study is to employ all systems necessary for significant electric power production at continuous high duty cycle operation; it is presently scheduled to be the final technological step before a Demonstration Reactor Plant (Demo). The scoping study tasks begin with an exploration and identification of principal problem areas and then concentrate on consideration and evaluation of alternate design choices for each of the following major systems: Plasma Engineering and Physics, Nuclear, Electromagnetics, Neutral Beam Injection, and Tritium Handling. In addition, consideration has been given to the integration of these systems and requirements arising out of their incorporation into an EPR. One intent of this study is to document the paths explored in search of the appropriate EPR characteristics. To satisfy this intent, the explorations are presented in chart form outlining possible options in key areas with extensive supporting footnotes. An important result of the scoping study has been the development and definition of an EPR reference design to serve as (1) a common focus for the continuing design study and (2) a guide for associated development programs. In addition, the study has identified research and development requirements essential to facilitate the successful conceptual design, construction, and operation of an EPR.

    Due to security and liability concerns, the research community has limited access to realistic large-scale power grid models to test and validate new operation and control methodologies. It is also difficult for industry to evaluate the relative value of competing new tools without a common platform for comparison. This report proposes to develop a large-scale virtual power grid model that retains basic features and represents future trends of major U.S. electric interconnections. This model will include realistic power flow and dynamics information as well as a relevant geospatial distribution of assets. This model will be made widely available to the research community for various power system stability and control studies and can be used as a common platform for comparing the efficacies of various new technologies.

    2016-04-05

    This descriptive scoping aims to understand how the prevalence of cyberbullying has been estimated across studies. A systematic scoping review of cyberbullying empirical studies was conducted by using three bibliographic databases to search for papers published between January 2004 and August 2014. A protocol was defined to identify the relevant papers. Papers selected were included in a data sheet developed by the authors to record specific findings. In total, 159 studies were included in the scoping review. Most of the prevalence studies were conducted in the last 4 years, mainly in North America (n= 77) and in Europe (n= 65). High methodological heterogeneity was found among the studies, which may contribute to explain variability in prevalence estimates. Cyberbullying experiences were assessed through several different perspectives: focused only on victims, focused only on perpetrators, or focused on both victims and perpetrators (without differentiating between if they are victims or perpetrators). Most of the studies tend to assess cybervictimization experiences. However, even considering the same perspective, the same country, and the same recall period, a high variability in the estimates was observed. As a main conclusion, the way in which the prevalence of cyberbullying is estimated is influenced by methodological research options.

    Previous studies investigating the mental health of migrants have shown mixed results. The increased availability of register data has led to a growing number of register-based studies in this research area. This is the first scoping review on the use of registry and record-linkage data to examine the mental health of migrant populations. The aim of this scoping review is to investigate the topics covered and to assess the results yielded from these studies. We used a scoping review methodology to search MedLine, PubMed, PsychINFO, Web of Science, and SCOPUS for all register-based studies on the mental health of migrants. Two reviewers screened all papers, independently, using iteratively applied inclusion and exclusion criteria. Using gradually broadening inclusion and exclusion criteria for maximum "scope," newly published criteria developed to appraise the methodological quality of record-linkage studies were applied to eligible papers and data were extracted in a charting exercise. A total of 1309 papers were screened and appraised, 51 of which met the eligibility and quality criteria and were included in the review. This review identified four major domains of register-based research within the topic of migrant mental health: rates and risks of psychiatric disorders, rates and risks of suicide mortality, the use of psychotropic drugs, and health service utilisation and mental health-related hospitalisation rates. We found that whilst migrants can be at an increased risk of developing psychotic disorders and suicide mortality, they are less likely to use psychotropic medication and mental health-related services. This review systematically charts the register-based studies on migrants' mental health for the first time. It shows the main topics and gaps in knowledge in this research domain, discusses the disadvantages of register-based studies, and suggests new directions for forthcoming studies.

    We explored the concept of design quality in relation to healthcare environments. In addition, we present a taxonomy that illustrates the wide range of terms used in connection with design quality in healthcare. High-quality physical environments can promote health and well-being. Developments in healthcare technology and methodology put high demands on the design quality of care environments, coupled with increasing expectations and demands from patients and staff that care environments be person centered, welcoming, and accessible while also supporting privacy and security. In addition, there are demands that decisions about the design of healthcare architecture be based on the best available information from credible research and the evaluation of existing building projects. The basic principles of Arksey and O'Malley's model of scoping review design were used. Data were derived from literature searches in scientific databases. A total of 18 articles and books were found that referred to design quality in a healthcare context. Design quality of physical healthcare environments involves three different themes: (i) environmental sustainability and ecological values, (ii) social and cultural interactions and values, and (iii) resilience of the engineering and building construction. Design quality was clarified herein with a definition. Awareness of what is considered design quality in relation to healthcare architecture could help to design healthcare environments based on evidence. To operationalize the concept, its definition must be clear and explicit and able to meet the complex needs of the stakeholders in a healthcare context, including patients, staff, and significant others.

It is recognized that the core damage frequency (CDF) of the sequence evaluated in this scoping effort would be considerably lower if evaluations considered new FLEX equipment being installed by industry. Nevertheless, because of uncertainties in instrumentation response when exposed to conditions beyond QE limits and alternate challenges associated with different sequences that may impact sensor performance, it is recommended that additional evaluations of instrumentation performance be completed to provide confidence that operators have access to accurate, relevant, and timely information on the status of reactor systems for a broad range of challenges associated with risk important severe accident sequences.

    A tremendous number of objective video quality measurement algorithms have been developed during the last two decades. Most of them either measure a very limited aspect of the perceived video quality or they measure broad ranges of quality with limited prediction accuracy. This paper lists several perceptual artifacts that may be computationally measured in an isolated algorithm and some of the modeling approaches that have been proposed to predict the resulting quality from those algorithms....

    The IEA Implementing Agreement for Renewable Energy Technology Deployment (IEA-RETD) investigated the opportunities for coupling renewable energy systems with fresh water supply systems. The four main conclusions of the scoping study, carried out by Ecofys, are: (1) Fresh water production based on desalination technologies provide most options for synergies with renewable energy production; (2) Linking desalination to renewable sources is currently not economically viable; (3) There is a large potential for small scale (decentralised) desalination plants; (4) Current commercially-sized desalination technologies are in need of a constant operation point. Reverse osmosis and thermal membrane technologies might give future synergies as deferrable load.

    2011-08-01

    Most survey data on sexual activities are obtained via face-to-face interviews, which are prone to misreporting of socially unacceptable behaviors. Demographers have developed various private response methods to minimize social desirability bias and improve the quality of reporting; however, these methods often limit the complexity of information collected. We designed a life history calendar-the Relationship History Calendar (RHC)-to increase the scope of data collected on sexual relationships and behavior while enhancing their quality. The RHC records detailed, 10-year retrospective information on sexual relationship histories. The structure and interview procedure draw on qualitative techniques, which could reduce social desirability bias. We compare the quality of data collected with the RHC with a standard face-to-face survey instrument through a field experiment conducted among 1,275 youth in Kisumu, Kenya. The results suggest that the RHC reduces social desirability bias and improves reporting on multiple measures, including higher rates of abstinence among males and multiple recent sexual partnerships among females. The RHC fosters higher levels of rapport and respondent enjoyment, which appear to be the mechanisms through which social desirability bias is minimized. The RHC is an excellent alternative to private response methods and could potentially be adapted for large-scale surveys.

    Full Text Available Liver diseases are one of the main causes of death, and their ever-increasing prevalence is threatening to cause significant damage both to individuals and society as a whole. This damage is especially serious for the economically active population in Korea. From the societal perspective, it is therefore necessary to consider the economic impacts associated with liver diseases, and identify interventions that can reduce the burden of these diseases. The cost-of-illness study is considered to be an essential evaluation technique in health care. By measuring and comparing the economic burdens of diseases to society, such studies can help health-care decision-makers to set up and prioritize health-care policies and interventions. Using economic theories, this paper introduces various study methods that are generally applicable to most disease cases for estimating the costs of illness associated with mortality, morbidity, disability, and other disease characteristics. It also presents concepts and scopes of costs along with different cost categories from different research perspectives in cost estimations. By discussing the epidemiological and economic grounds of the cost-of-illness study, the reported results represent useful information about several evaluation techniques at an advanced level, such as cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis.

    This article discusses a scoping study on implementing radio frequency identification device (RFID) in a hospital library context, conducted by Joseph Norwood for his MA dissertation at the University of Brighton. The study was carried out during the summer of 2011 to support possible RFID implementation at the Brighton and Sussex University Hospitals (BSUH) Trust, and the library staff were able to use the findings to good effect to create a business plan. This article also acts as the template for the new Dissertations into Practice feature, which was introduced in the March issue (Marshall, A. Health Information and Libraries Journal 2012, 29, 72). The dissertation highlighted here is very practical in nature and had immediate and quantifiable benefits for the Trust library. Future feature articles are likely to reflect the range of health-related dissertation topics which students choose and will include studies on user information behaviour, information services related to mental health and well-being, as well as the impact of technology on health-related library or information services.AM.

  5. Broadening the Quality and Capabilities of the EarthScope Alaska Transportable Array

    Busby, R. W.

    2016-12-01

    In 2016, the EarthScope Transportable Array (TA) program will have 195 broadband seismic stations operating in Alaska and western Canada. This ambitious project will culminate in a network of 268 new or upgraded real-time seismic stations operating through 2019. The challenging environmental conditions and the remoteness of Alaska have motivated a new method for constructing a high-quality, temporary seismic network. The Alaska TA station design builds on experience of the Lower 48 TA deployment and adds design requirements because most stations are accessible only by helicopter. The stations utilize new high-performance posthole sensors, a specially built hammer/auger drill, and lightweight lithium ion batteries to minimize sling loads. A uniform station design enables a modest crew to build the network on a short timeline and operate them through the difficult conditions of rural Alaska. The Alaska TA deployment has increased the quality of seismic data, with some well-sited 2-3 m posthole stations approaching the performance of permanent Global Seismic Network stations emplaced in 100 m boreholes. The real-time data access, power budget, protective enclosure and remote logistics of these TA stations has attracted collaborations with NASA, NOAA, USGS, AVO and other organizations to add auxiliary sensors to the suite of instruments at many TA stations. Strong motion sensors have been added to (18) stations near the subduction trench to complement SM stations operated by AEC, ANSS and GSN. All TA and most upgraded stations have pressure and infrasound sensors, and 150 TA stations are receiving a Vaisala weather sensor, supplied by the National Weather Service Alaska Region and NASA, capable of measuring temperature, pressure, relative humidity, wind speed/direction, and precipitation intensity. We are also installing about (40) autonomous soil temperature profile kits adjacent to northern stations. While the priority continues to be collecting seismic data, these

    To assess current scleral lens prescription and management practices by conducting an international online survey of eye care providers. The SCOPE (Scleral Lenses in Current Ophthalmic Practice: an Evaluation) study group designed and administered an online survey regarding current scleral lens prescription and management practices. The survey was open from January 15 to March 31, 2015, and generated 723 responses from individuals who had fit at least 5 patients with scleral lenses. Respondents (n=663) prescribed scleral lenses that ranged from 15 to 17 mm in diameter (65%), smaller than 15 mm (18%), and larger than 18 mm (17%). More than 50 lens designs were identified. Average daily wearing time of 11.8 hr was consistent across 651 respondents, and 475/651 (73%) recommended midday removal on some, most, or all days. Most respondents recommended nonpreserved saline to fill the bowl of the lens before application (single-use vials, 392/653 [60%]; bottled products, 372/653 [57%]). A hydrogen peroxide-based disinfection system was the most commonly recommended care product (397/651 [61%]). A reasonable degree of consensus exists regarding some aspects of scleral lens prescription and management (average lens diameter, daily wearing time, and use of nonpreserved products for lens application). Further study is needed to develop evidence-based guidelines for scleral lens prescription and management.

    2010-10-01

    Research evidence demonstrates that offering language choice to patients enhances the quality of healthcare provision. This has implications for the preparation of nurses for practice in bilingual settings, where legislation often leads to demands for health services in both languages and bilingual competence amongst healthcare providers. This paper reports on a scoping study of bilingual provision in nurse education in the bilingual context of Wales, UK, as a means of informing the evidence base for national strategic planning. The study incorporated three elements: (i) literature analysis (ii) policy review and (iii) stakeholder consultation (n=70). Six themes emerged from the stakeholder consultation, reflecting the main drivers and barriers associated with bilingual provision in course delivery. These themes aligned with findings identified from the policy and literature review that related to strategic, organisational and individual influences on bilingual educational provision. Strategic planning for bilingual provision in nurse education in Wales should take account of the factors that affect provision at different levels. These factors feature across bilingual settings outside the UK, thus giving the study international relevance and scope to inform the delivery of nurse education that meets the needs of wider diverse language communities.

  9. Data Citation Policies of Data Providers within the scope of Longitudinal Studies in Life Course Research

    Reinhold, A.; Rittberger, M.; Mahrholz, N.

    2016-07-01

    In this article, a small-scale case study analyzing the nature of data citation policies within the scope of longitudinal studies in life course research is presented. The sample consists of eight data providers from Europe, North-America and Australia and was evaluated with regard to eight criteria which potentially affect data citation behavior of researchers in the field, for example the wording of data citation obligations or sanctions for not citing research data in accordance to given requirements. The study demonstrates that research data providers follow a wide range of approaches to data citation, especially in terms of data citation location within a publication as well as disposal obligations for data-related publications. However, this diversity might lead to inconsistency in data citation behaviour and also to a general lack of comparability of data citation quantity and quality as relevant factors in research evaluation.

    Lins, Liliane; Carvalho, Fernando Martins

    2016-01-01

    According to the 36-Item Short Form Health Survey questionnaire developers, a global measure of health-related quality of life such as the “SF-36 Total/Global/Overall Score” cannot be generated from the questionnaire. However, studies keep on reporting such measure. This study aimed to evaluate the frequency and to describe some characteristics of articles reporting the SF-36 Total/Global/Overall Score in the scientific literature. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was adapted to a scoping review. We performed searches in PubMed, Web of Science, SCOPUS, BVS, and Cochrane Library databases for articles using such scores. We found 172 articles published between 1997 and 2015; 110 (64.0%) of them were published from 2010 onwards; 30.0% appeared in journals with Impact Factor 3.00 or greater. Overall, 129 (75.0%) out of the 172 studies did not specify the method for calculating the “SF-36 Total Score”; 13 studies did not specify their methods but referred to the SF-36 developers’ studies or others; and 30 articles used different strategies for calculating such score, the most frequent being arithmetic averaging of the eight SF-36 domains scores. We concluded that the “SF-36 Total/Global/Overall Score” has been increasingly reported in the scientific literature. Researchers should be aware of this procedure and of its possible impacts upon human health. PMID:27757230

    Implementation fidelity is critical to the internal and external validity of implementation research. Much of what is written about implementation fidelity addresses fidelity of evidence-informed interventions rather than fidelity of implementation strategies. The documentation and reporting of fidelity to implementation strategies requires attention. Therefore, in this scoping review, we identify the extent and quality of documentation and reporting of fidelity of implementation strategies that were used to implement evidence-informed interventions. A six-stage methodological framework for scoping studies guided our work. Studies were identified from the outputs of the Effective Practice and Organization of Care (EPOC) review group within the Cochrane Database of Systematic Reviews. EPOC's primary focus, implementation strategies influencing provider behavior change, optimized our ability to identify articles for inclusion. We organized the retrieved articles from the systematic reviews by journal and selected the three journals with the largest number of retrieved articles. Using a data extraction tool, we organized retrieved article data from these three journals. In addition, we summarized implementation strategies using the EPOC categories. Data extraction pertaining to the quality of reporting the fidelity of implementation strategies was facilitated with an "Implementation Strategy Fidelity Checklist" based on definitions adapted from Dusenbury et al. We conducted inter-rater reliability checks for all of the independently scored articles. Using linear regression, we assessed the fidelity scores in relation to the publication year. Seventy-two implementation articles were included in the final analysis. Researchers reported neither fidelity definitions nor conceptual frameworks for fidelity in any articles. The most frequently employed implementation strategies included distribution of education materials (n = 35), audit and feedback (n = 32), and

    Rigid video laryngoscopes are popular alternatives to direct laryngoscopy for intubation, but further large scale prospective studies comparing these devices to direct laryngoscopy in routine anesthesiology practice are needed. We hypothesized that the first pass success rate with one particular video laryngoscope, the GlideScope, would be higher than the success rate with direct laryngoscopy. 3831 total intubation attempts were tracked in an observational study comparing first-pass success rate using a Macintosh or Miller-style laryngoscope with the GlideScope. Propensity scoring was then used to select 626 subjects matched between the two groups based on their morphologic traits. Comparing the GlideScope and direct laryngoscopy groups suggested that intubation would be more difficult in the GlideScope group based on the Mallampati class, cervical range of motion, mouth opening, dentition, weight, and past intubation history. Thus, a propensity score based on these factors was used to balance the groups into two 313 patient cohorts. Direct laryngoscopy was successful in 80.8% on the first-pass intubation attempt, while the GlideScope was successful in 93.6% (p risk difference of 0.128 with a 95% CI of 0.0771 - 0.181). A greater first-attempt success rate was found when using the GlideScope versus direct laryngoscopy. In addition, the GlideScope was found to be 99% successful for intubation after initial failure of direct laryngoscopy, helping to reduce the incidence of failed intubation.

    The healthcare of people with HIV is transitioning from specialty care to the primary healthcare (PHC) system. However, many of the performance indicators used to measure the quality of HIV care pre-date this transition. The goal of this work was to examine how existing HIV care performance indicators measure the comprehensive and longitudinal care offered in a PHC setting. A scoping review consisting of peer-reviewed and grey literature searches was performed. Two reviewers evaluated study eligibility and indicators in documents meeting inclusion criteria were extracted into a database. Indicators were matched to a PHC performance measurement framework to determine their applicability for evaluating quality of care in the PHC setting. The literature search identified 221 publications, of which 47 met inclusion criteria. 1184 indicators were extracted and removal of duplicates left 558 unique indicators. A majority of the 558 indicators fell under the 'secondary prevention' (12%) and 'care of chronic conditions' (33%) domains when indicators were matched to the PHC performance framework. Despite the imbalance, nearly all performance domains in the PHC framework were populated by at least one indicator with significant concentrations in domains such as patient-provider relationship, patient satisfaction, population and community characteristics, and access to care. Existing performance frameworks for the care of people with HIV provide a comprehensive set of indicators that align well with a PHC performance framework. Nonetheless, some important elements of care, such as patient-reported outcomes, are poorly covered by existing indicators. Advancing our understanding of how the experience of care for people with HIV is impacted by changes in health services delivery, specifically more care within the PHC system, will require performance indicators to capture this aspect of HIV care.

    Full Text Available Human travel behaviour has been addressed in many transport studies, where travel survey methods have been widely used to collect self-reported insights of daily mobility patterns. However, since the introduction of Global Navigation Satellite Systems (GNSS and more recently smartphones with built-in GNSS, researchers have adopted these ubiquitous devices as tools for collecting mobility behaviour data. Although most studies recognize the applicability of this technology, it still has limitations. These are rarely addressed in a quantified manner. Often the quality of the collected data tends to be overestimated and these errors propagate into the aggregated results providing incomplete knowledge of the levels of confidence of the results and conclusions. In this study, we focus on the completeness aspects of data quality using GNSS data from four campaigns in the Flanders region of Belgium. The empirical results are based on mobility behaviour data collected through smartphones and include more than 450 participants over a period of twenty-nine months. Our findings show which transport mode is affected the most and how land use affects the quality of the collected data. In addition, we provide insights into the time to first fix that can be used for a better estimation of travel patterns.

    To describe the scope and breadth of knowledge currently available regarding the integration of rehabilitation and primary care services. Peer-reviewed journals were searched using CINAHL, MEDLINE, and EBM Reviews for the years 1995 through 2007. This process identified 172 items. To be considered for the subsequent review, the article had to describe a service delivery program that offered primary care and rehabilitation, or services specifically designed for people with chronic conditions/disabilities. Further, it had to be available in English or French. No methodological limitations were applied to screen for levels of evidence. Based on these criteria, 38 articles remained that pertained to both primary care and rehabilitation. These were reviewed, sorted, and categorized to discover commonalities and differences among the approaches used to integrating rehabilitation into primary care. In consultation with the team of investigators, it was determined that there were 6 different models for providing primary health care and rehabilitation services in an integrated approach: clinic, outreach, self-management, community-based rehabilitation, shared care, and case management. In addition, a number of themes were identified across models that may act as either supports or impediments to the integration of rehabilitation services into primary care settings: team approach, interprofessional trust, leadership, communication, compensation, accountability, referrals, and population-based approach. Rehabilitation providers interested in working in the primary care sector may be assisted in conceptualizing the benefits that they bring to the setting by considering these models and issues.

    For this task LLNL will examine the vulnerability of drinking water supplies in foothills and higher elevation areas to climate change impacts on recharge. Recharge locations and vulnerability will be determined through examination of groundwater ages and noble gas recharge temperatures in high elevation basins. LLNL will determine whether short residence times are common in one or more subalpine basin. LLNL will measure groundwater ages, recharge temperatures, hydrogen and oxygen isotopes, major anions and carbon isotope compositions on up to 60 samples from monitoring wells and production wells in these basins. In addition, a small number of carbon isotope analyses will be performed on surface water samples. The deliverable for this task will be a technical report that provides the measured data and an interpretation of the data from one or more subalpine basins. Data interpretation will: (1) Consider climate change impacts to recharge and its impact on water quality; (2) Determine primary recharge locations and their vulnerability to climate change; and (3) Delineate the most vulnerable areas and describe the likely impacts to recharge.

    Microgrid demonstrations and deployments are expanding in US power systems and around the world. Although goals are specific to each site, these microgrids have demonstrated the ability to provide higher reliability and higher power quality than utility power systems and improved energy utilization. The vast majority of these microgrids are based on AC power transfer because this has been the traditionally dominant power delivery scheme. Independently, manufacturers, power system designers and researchers are demonstrating and deploying DC power distribution systems for applications where the end-use loads are natively DC, e.g., computers, solid-state lighting, and building networks. These early DC applications may provide higher efficiency, added flexibility, reduced capital costs over their AC counterparts. Further, when onsite renewable generation, electric vehicles and storage systems are present, DC-based microgrids may offer additional benefits. Early successes from these efforts raises a question - can a combination of microgrid concepts and DC distribution systems provide added benefits beyond what has been achieved individually?

    This Air Pollution Control System (APCS) Conceptual Design and Evaluation study was conducted to evaluate a high-performance (APC) system for minimizing air emissions from mixed waste thermal treatment systems. Seven variations of high-performance APCS designs were conceptualized using several design objectives. One of the system designs was selected for detailed process simulation using ASPEN PLUS to determine material and energy balances and evaluate performance. Installed system capital costs were also estimated. Sensitivity studies were conducted to evaluate the incremental cost and benefit of added carbon adsorber beds for mercury control, specific catalytic reduction for NO{sub x} control, and offgas retention tanks for holding the offgas until sample analysis is conducted to verify that the offgas meets emission limits. Results show that the high-performance dry-wet APCS can easily meet all expected emission limits except for possibly mercury. The capability to achieve high levels of mercury control (potentially necessary for thermally treating some DOE mixed streams) could not be validated using current performance data for mercury control technologies. The engineering approach and ASPEN PLUS modeling tool developed and used in this study identified APC equipment and system performance, size, cost, and other issues that are not yet resolved. These issues need to be addressed in feasibility studies and conceptual designs for new facilities or for determining how to modify existing facilities to meet expected emission limits. The ASPEN PLUS process simulation with current and refined input assumptions and calculations can be used to provide system performance information for decision-making, identifying best options, estimating costs, reducing the potential for emission violations, providing information needed for waste flow analysis, incorporating new APCS technologies in existing designs, or performing facility design and permitting activities.

  12. A Scoping Study on the Ethics of Health Systems Research.

    2016-12-01

    Currently, health systems research (HSR) is reviewed by the same ethical standards as clinical research, which has recently been argued in the literature to be an inappropriate standard of evaluation. The issues unique to HSR warrant a different review by research ethics committees (RECs), as it does not impose the same risks to study participants as other types of clinical or public health research. However, there are limited tools and supporting documents that clarify the ethical considerations. Therefore, there is a need for additional reflection around ethical review of HSR and their consideration by RECs. The purpose of this paper is to review, understand, and synthesize the current state of literature and practice to inform these deliberations and the larger discourse on ethics review guidelines for HSR. This paper presents a review of the literature on ethics of HSR in the biomedical, public health, and implementation research to identify ethical considerations specific to HSR; and to identify examples of commonly available guidance and/or tools for the ethical review of HSR studies. Fifteen articles were identified on HSR ethics issues, and forty-two international academic institutions were contacted (of the responses (n=29), no institution had special ethical guidelines for reviewing HSR) about their HSR ethics review guidelines. There appears to be a clear gap in the current health research ethics discourse around health systems research ethics. This review serves as a first step (to better understand the current status) towards a larger dialogue on the topic.

    Heat exhaust is a challenge for ITER and becomes even more of an issue for devices beyond ITER. The main reason for this is that the power produced in the core scales as R{sup 3} while relying on standard exhaust physics results in the heat exhaust scaling as R{sup 1} (R is the major radius). ITER has used SOLPS (B2-EIRENE) to design the ITER divertor, as well as to provide a database that supports the calculations of the ITER operational parameter space. The typical run time for such SOLPS runs is of the order 3 months (for D+C+He using EIRENE to treat the neutrals kinetically with an extensive choice of atomic and molecular physics). Future devices will be expected to radiate much of the power before it crosses the separatrix, and this requires treating extrinsic impurities such as Ne, Ar, Kr and Xe - the large number of charge states puts additional pressure on SOLPS, further slowing down the code. For design work of future machines, fast models have been implemented in system codes but these are usually unavoidably restricted in the included physics. As a bridge between system studies and detailed SOLPS runs, SOLPS offers a number of possibilities to speed up the code considerably at the cost of reducing the fidelity of the physics. By employing a fluid neutral model, aggressive bundling of the charge state of impurities, and reducing the size of the grids used, the run time for one second of physics time (which is often enough for the divertor to come to a steady state) can be reduced to approximately one day. This work looks at the impact of these trade-offs in the physics by comparing key parameters for different simulation assumptions. (copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Background The health system of Bangladesh is haunted by challenges of accessibility and affordability. Despite impressive gains in many health indicators, recent evidence has raised concerns regarding the utilization, quality and equity of healthcare. In the context of new and unfamiliar public health challenges including high population density and rapid urbanization, eHealth and mHealth are being promoted as a route to cost-effective, equitable and quality healthcare in Bangladesh. The aim of this paper is to highlight such initiatives and understand their true potential. Methods This scoping study applies a combination of research tools to explore 26 eHealth and mHealth initiatives in Bangladesh. A screening matrix was developed by modifying the framework of Arksey & O’Malley, further complemented by case study and SWOT analysis to identify common traits among the selected interventions. The WHO health system building blocks approach was then used for thematic analysis of these traits. Results Findings suggest that most eHealth and mHealth initiatives have proliferated within the private sector, using mobile phones. The most common initiatives include tele-consultation, prescription and referral. While a minority of projects have a monitoring and evaluation framework, less than a quarter have undertaken evaluation. Most of the initiatives use a health management information system (HMIS) to monitor implementation. However, these do not provide for effective sharing of information and interconnectedness among the various actors. There are extremely few individuals with eHealth training in Bangladesh and there is a strong demand for capacity building and experience sharing, especially for implementation and policy making. There is also a lack of research evidence on how to design interventions to meet the needs of the population and on potential benefits.

    To reduce child mortality and improve health in Ghana boreholes and wells are being installed across the country by the private sector, NGO's and the Ghanaian government. Water quality is not generally monitored once a water source has been improved. Water supplies were sampled across Ghana from mostly boreholes, wells and rivers as well as some piped water from the different regions and analysed for the chemical quality. Chemical water quality was found to exceed the WHO guidelines in 38% of samples, while pH varied from 3.7 to 8.9. Excess levels of nitrate (NO(3)(-)) were found in 21% of the samples, manganese (Mn) and fluoride (F(-)) in 11% and 6.7%, respectively. Heavy metals such as lead (Pb), arsenic (As) and uranium (U) were localised to mining areas. Elements without health based guideline values such as aluminium (Al, 95%) and chloride (Cl, 5.7%) were found above the provisional guideline value. Economic information was gathered to identify water costs and ability to pay. Capital costs of wells and boreholes are about pound1200 and pound3800 respectively. The majority of installation costs are generally paid by the government or NGO's, while the maintenance is expected to be covered by the community. At least 58% of the communities had a water payment system in place, either an annual fee/one-off fee or "pay-as-you-fetch". The annual fee was between pound0.3-21, while the boreholes had a water collection fee of pound0.07-0.7/m(3), many wells were free. Interestingly, the most expensive water ( pound2.9-3.5/m(3)) was brought by truck. Many groundwater sources were not used due to poor chemical water quality. Considering the cost of unsuccessful borehole development, the potential for integrating suitable water treatment into the capital and maintenance costs of water sources is discussed. Additionally, many sources were not in use due to lack of water capacity, equipment malfunction or lack of economic resources to repair and maintain equipment. Those

    Full Text Available Abstract Scoping studies have been used across a range of disciplines for a wide variety of purposes. However, their value is increasingly limited by a lack of definition and clarity of purpose. The UK's Service Delivery and Organisation Research Programme (SDO has extensive experience of commissioning and using such studies; twenty four have now been completed. This review article has four objectives; to describe the nature of the scoping studies that have been commissioned by the SDO Programme; to consider the impact of and uses made of such studies; to provide definitions for the different elements that may constitute a scoping study; and to describe the lessons learnt by the SDO Programme in commissioning scoping studies. Scoping studies are imprecisely defined but usually consist of one or more discrete components; most commonly they are non-systematic reviews of the literature, but other important elements are literature mapping, conceptual mapping and policy mapping. Some scoping studies also involve consultations with stakeholders including the end users of research. Scoping studies have been used for a wide variety of purposes, although a common feature is to identify questions and topics for future research. The reports of scoping studies often have an impact that extends beyond informing research commissioners about future research areas; some have been published in peer reviewed journals, and others have been published in research summaries aimed at a broader audience of health service managers and policymakers. Key lessons from the SDO experience are the need to relate scoping studies to a particular health service context; the need for scoping teams to be multi-disciplinary and to be given enough time to integrate diverse findings; and the need for the research commissioners to be explicit not only about the aims of scoping studies but also about their intended uses. This necessitates regular contact between researchers and

    Full Text Available Background. Critical care transfers (CCT refer to the high level of care given during transport (via ambulance, helicopter or fixed-wing aircraft of patients who are of high acuity. In South Africa (SA, advanced life support (ALS paramedics undertake CCTs. The scope of ALS in SA has no extended protocol regarding procedures or medications in terms of dealing with these CCTs. Aim. The aim of this study was to obtain the opinions of several experts in fields pertaining to critical care and transport and to gain consensus on the skills and scope-of-practice requirements of paramedics undertaking CCTs in the SA setting. Methods. A modified Delphi study consisting of three rounds was undertaken using an online survey platform. A heterogeneous sample (n=7, consisting of specialists in the fields of anaesthesiology, emergency medicine, internal medicine, critical care, critical care transport and paediatrics, was asked to indicate whether, in their opinion, selected procedures and medications were needed within the scope of practice of paramedics undertaking CCTs. Results. After three rounds, consensus was obtained in 70% (57/81 of procedures and medications. Many of these items are not currently within the scope of paramedics’ training. The panel felt that paramedics undertaking these transfers should have additional postgraduate training that is specific to critical care. Conclusion. Major discrepancies exist between the current scope of paramedic practice and the suggested required scope of practice for CCTs. An extended scope of practice and additional training should be considered for these practitioners.

    Integrated resource planning (IRP) is an approach to utility resource planning that integrates the evaluation of supply- and demand-site options for providing energy services at the least cost. Many utilities practice IRP; however, most studies about IRP focus on investor-owned utilities (IOUs). This scoping study investigates the IRP activities and needs of public utilities (not-for-profit utilities, including federal, state, municipal, and cooperative utilities). This study (1) profiles IRP-related characteristics of the public utility sector, (2) articulates the needs of public utilities in understanding and implementing IRP, and (3) identifies strategies to advance IRP principles in public utility planning.

    Implementing national policies may threaten the eligibility of renewable energy projects for Clean Development Mechanism/Joint Implementation (CDM/JI), thus reducing international development financing. Countries hence need to be very careful when crafting their national promotion policies. The objectives of the Renewable Energy Technology Deployment (IEA-RETD) project were to perform a scoping study on the interplay between national Renewable Energy (RE) promotion policies and international carbon trade. The study summarizes the ongoing discussion, describes the main barriers that may hinder -- or at least not sufficiently support -- the implementation of national RE promotion policies, and provides suggestions for removing these barriers.

    Full Text Available Cross-coupling reactions between 2-methyl-2-propen-1-ol and various boronic acids are used to obtain aromatic-(2-methylallyl derivatives. However, deboronation or isomerization side reactions may occur for several boronic acids. We describe herein the synthesis of original alkenes with good yields under mild reaction conditions that decrease these side reactions. The scope of this environmentally benign reaction is thereby extended to a wide variety of boronic acids. A mechanistic study was conducted and suggested a plausible catalytic cycle mechanism, pointing to the importance of the Lewis acidity of the boronic acid used.

    Recent avoidable failures in patient care highlight the ongoing need for evidence to support improvements in patient safety. According to the most recent reviews, there is a dearth of economic evidence related to patient safety. These reviews characterise an evidence gap in terms of the scope and quality of evidence available to support resource allocation decisions. This protocol is designed to update and improve on the reviews previously conducted to determine the extent of methodological progress in economic analyses in patient safety. A broad search strategy with two core themes for original research (excluding opinion pieces and systematic reviews) in 'patient safety' and 'economic analyses' has been developed. Medline, Econlit and National Health Service Economic Evaluation Database bibliographic databases will be searched from January 2007 using a combination of medical subject headings terms and research-derived search terms (see table 1). The method is informed by previous reviews on this topic, published in 2012. Screening, risk of bias assessment (using the Cochrane collaboration tool) and economic evaluation quality assessment (using the Drummond checklist) will be conducted by two independent reviewers, with arbitration by a third reviewer as needed. Studies with a low risk of bias will be assessed using the Drummond checklist. High-quality economic evaluations are those that score >20/35. A qualitative synthesis of evidence will be performed using a data collection tool to capture the study design(s) employed, population(s), setting(s), disease area(s), intervention(s) and outcome(s) studied. Methodological quality scores will be compared with previous reviews where possible. Effect size(s) and estimate uncertainty will be captured and used in a quantitative synthesis of high-quality evidence, where possible. Formal ethical approval is not required as primary data will not be collected. The results will be disseminated through a peer

  5. The TITAN Reversed-Field Pinch fusion reactor study: Scoping phase report

    Energy Technology Data Exchange (ETDEWEB)

    1987-01-01

    The TITAN research program is a multi-institutional effort to determine the potential of the Reversed-Field Pinch (RFP) magnetic fusion concept as a compact, high-power-density, and ''attractive'' fusion energy system from economic (cost of electricity, COE), environmental, and operational viewpoints. In particular, a high neutron wall loading design (18 MW/m/sup 2/) has been chosen as the reference case in order to quantify the issue of engineering practicality, to determine the physics requirements and plasma operating mode, to assess significant benefits of compact systems, and to illuminate the main drawbacks. The program has been divided into two phases, each roughly one year in length: the Scoping Phase and the Design Phase. During the scoping phase, the TITAN design team has defined the parameter space for a high mass power density (MPD) RFP reactor, and explored a variety of approaches to the design of major subsystems. Two major design approaches consistent with high MPD and low COE, the lithium-vanadium blanket design and aqueous loop-in-pool design, have been selected for more detailed engineering evaluation in the design phase. The program has retained a balance in its approach to investigating high MPD systems. On the one hand, parametric investigations of both subsystems and overall system performance are carried out. On the other hand, more detailed analysis and engineering design and integration are performed, appropriate to determining the technical feasibility of the high MPD approach to RFP fusion reactors. This report describes the work of the scoping phase activities of the TITAN program. A synopsis of the principal technical findings and a brief description of the TITAN multiple-design approach is given. The individual chapters on Plasma Physics and Engineering, Parameter Systems Studies, Divertor, Reactor Engineering, and Fusion Power Core Engineering have been cataloged separately.

    At the request of the U.S. Department of Energy Office of River Protection, Pacific Northwest National Laboratory (PNNL) conducted a scoping study to investigate supplemental technologies for supplying vertical fluid motion and enhanced mixing in Waste Treatment and Immobilization Plant (WTP) vessels designed for high solids processing. The study assumed that the pulse jet mixers adequately mix and shear the bottom portion of a vessel. Given that, the primary function of a supplemental technology should be to provide mixing and shearing in the upper region of a vessel. The objective of the study was to recommend a mixing technology and configuration that could be implemented in the 8-ft test vessel located at Mid-Columbia Engineering (MCE). Several mixing technologies, primarily airlift circulator (ALC) systems, were evaluated in the study. This technical report contains a review of ALC technologies, a description of the PNNL testing and accompanying results, and recommended features of an ALC system for further study.

    Large scope distribution software technology will be a mainstream technology of software development for coming years. But Large scope distribution software development means high software complexity and expensive expenditure. Software architecture acts as blueprint of software system and turns into one of the determinant factor for development~ especially for large scope software in distribution environment. This paper analyzes the flexibility and suitability of software agent to construct LSSA (Large scope software architecture), then ADALSS(Agent-based distributed architecture of large scope software) based on agent federation is presented, and ADALSS mechanism is illustrated as well. Concerning implementation, a layer model of ADALSS based on interface is described. It will be a dominant pattern for future large scope software development to regard each agent as an object and to combine this agent object with ADALSS model.

    Introduction In a context of constrained resources, the efficacy of interventions is a pivotal aim of healthcare systems worldwide. Efficacy of healthcare interventions is highly compromised if clinical reasoning (CR), the process that practitioners use to plan, direct, perform and reflect on client care, is not optimal. The CR process of health professionals is influenced by the institutional dimension (ie, legal, regulatory, administrative and organisational aspects) of their societal and practice contexts. Although several studies have been conducted with respect to the institutional dimension influencing health professionals’ CR, no clear integration of their results is yet available. The aim of this study is to synthesise and disseminate current knowledge on the influence of the institutional dimension of contexts on health professionals’ CR. Methods and analysis A scoping study of the scientific literature from January 1980 to March 2013 will be undertaken to summarise and disseminate research findings about the influence of the institutional dimension on CR. Numerous databases (n=18) from three relevant fields (healthcare, health law and politics and management) will be searched. Extended search strategies will include the manual search of bibliographies, health-related websites, public registries and journals of interest. Data will be collected and analysed using a thematic chart and content analysis. A systematic multidisciplinary team approach will allow optimal identification of relevant studies, as well as effective and valid content analysis and dissemination of the results. Discussion This scoping study will provide a rigorous, accurate and up-to-date synthesis of existing knowledge regarding: (1) those aspects of the institutional dimension of health professionals’ societal and practice contexts that impact their CR and (2) how these aspects influence health professionals’ CR. Through the synergy of a multidisciplinary research team from a

    A team from the Universities of Wisconsin, Washington, and Illinois performed an engineering scoping study of critical issues for field-reversed configuration (FRC) power plants. The key tasks for this research were (1) systems analysis for deuterium-tritium (D-T) FRC fusion power plants, and (2) conceptual design of the blanket and shield module for an FRC fusion core. For the engineering conceptual design of the fusion core, the project team focused on intermediate-term technology. For example, one decision was to use steele structure. The FRC systems analysis led to a fusion power plant with attractive features including modest size, cylindrical symmetry, good thermal efficiency (52%), relatively easy maintenance, and a high ratio of electric power to fusion core mass, indicating that it would have favorable economics.

  11. The relevance and role of homestays in medical education: a scoping study.

    The community-based medical education curriculum is growing in popularity as a strategy to bring universal health coverage to underserved communities by providing medical students with hands-on training in primary health care. Accommodation and immersion of medical students within the community will become increasingly important to the success of community-based curricula. In the context of tourism, homestays, where local families host guests, have shown to provide an immersive accommodation experience. By exploring homestays in the educational context, this scoping study investigates their role in providing an immersive pedagogical experience for medical students. A scoping review was performed using the online databases ScienceDirect and the Duke University Library Database, which searches Academic Search Complete, JSTOR, LexisNexis Academic, Web of Science, Proquest, PubMed and WorldCat. Using the inclusion term 'homestays' and excluding the term 'tourism', 181 results were returned. AClose assessment using inclusion criteria narrowed this to 14 relevant articles. There is very little published research specific to the experience of medical students in community homestays, indicating a gap in the literature. However, the existing educational outcomes suggest homestays may have the potential to serve a significant role in medical education, especially as a component of decentralised or community-based programmes. The literature reveals that educational homestays influence language learning, cultural immersion, and the development of professional skills for health science careers. These outcomes relate to the level of engagement between students and hosts, including the catalytic role of community liaisons. Homestays offer a unique depth of experience that has the potential to enrich the education of participating students, and require further research, particularly in the context of distributed and decentralised training platforms for medical and health sciences

    Full Text Available To study the variation of the pressure relief scope and the stress around hydraulic flushing borehole, the theory of coalrock damage was utilized to distinguish the interaction area of water-jet and coal-rock into the coal-rock crushing area, the water-jet pressure stagnation area, the transition area and the original stress recovery area of coal-rock. Based on the actual occurrence conditions of the coal seam, the pressure variation and relief scope around the hydraulic flushing borehole were analyzed and simulated by RFPA2D-Flow software. The results showed that a relief area with the radius of 5.0 ~ 6.0 m around the borehole formed due to the hydraulic flushing with the pressure relief of 0.038 ~ 6.545 MPa, and the maximum principal stress is 15.85 MPa with a distance of 6.8 m from the inspected hole where stress concentration appeared. After hydraulic flushing test, the diameter (441.8 ~ 1171.6 mm of the hole which can be an expression of coal crushing area size, was calculated based on the examination of the coal amount through the trial process, and it can be drawn that the pressure relief area must be larger than that of the coal-rock crushing area. Meanwhile, the measured pressures relief range(5.96 ~ 6.62 m is basically consistent with the numerical simulation result (5.0 ~ 6.0 m which verified the accuracy of the simulation analysis, according to the distance from the inspection drilling to the hydraulic flushing borehole and the decreased degree of the gas content in the inspection hole by the way of Gas Content.

    The Buildings of the Future Scoping Study, funded by the U.S. Department of Energy (DOE) Building Technologies Office, seeks to develop a vision for what U.S. mainstream commercial and residential buildings could become in 100 years. This effort is not intended to predict the future or develop a specific building design solution. Rather, it will explore future building attributes and offer possible pathways of future development. Whether we achieve a more sustainable built environment depends not just on technologies themselves, but on how effectively we envision the future and integrate these technologies in a balanced way that generates economic, social, and environmental value. A clear, compelling vision of future buildings will attract the right strategies, inspire innovation, and motivate action. This project will create a cross-disciplinary forum of thought leaders to share their views. The collective views will be integrated into a future building vision and published in September 2015. This report presents a research framework for the vision development effort based on a literature survey and gap analysis. This document has four objectives. First, it defines the project scope. Next, it identifies gaps in the existing visions and goals for buildings and discusses the possible reasons why some visions did not work out as hoped. Third, it proposes a framework to address those gaps in the vision development. Finally, it presents a plan for a series of panel discussions and interviews to explore a vision that mitigates problems with past building paradigms while addressing key areas that will affect buildings going forward.

    Full Text Available Abstract Background The current profile of residents living in Canadian nursing homes includes elder persons with complex physical and social needs. High resident acuity can result in increased staff workload and decreased quality of work life. Aims Safer Care for Older Persons [in residential] Environments is a two year (2010 to 2012 proof-of-principle pilot study conducted in seven nursing homes in western Canada. The purpose of the study is to evaluate the feasibility of engaging front line staff to use quality improvement methods to integrate best practices into resident care. The goals of the study are to improve the quality of work life for staff, in particular healthcare aides, and to improve residents' quality of life. Methods/design The study has parallel research and quality improvement intervention arms. It includes an education and support intervention for direct caregivers to improve the safety and quality of their care delivery. We hypothesize that this intervention will improve not only the care provided to residents but also the quality of work life for healthcare aides. The study employs tools adapted from the Institute for Healthcare Improvement's Breakthrough Series: Collaborative Model and Canada's Safer Healthcare Now! improvement campaign. Local improvement teams in each nursing home (1 to 2 per facility are led by healthcare aides (non-regulated caregivers and focus on the management of specific areas of resident care. Critical elements of the program include local measurement, virtual and face-to-face learning sessions involving change management, quality improvement methods and clinical expertise, ongoing virtual and in person support, and networking. Discussion There are two sustainability challenges in this study: ongoing staff and leadership engagement, and organizational infrastructure. Addressing these challenges will require strategic planning with input from key stakeholders for sustaining quality improvement

    2015-04-01

    How does the organizational micro culture in emergency departments (EDs) impact the care of older adults presenting with a complaint or condition perceived as non-acute? This scoping study reviews the literature and maps three levels of ED culture (artifacts, values and beliefs, and assumptions). Findings on the artifact level indicate that EDs are poorly designed for the needs of older adults. Findings on the ED value and belief level indicate that EDs are for urgent cases (not geriatric care), that older adults do not receive the care and respect they should be given, that older adults require too much time, and that the basic nursing needs of older adults are not a priority for ED nurses. Finally, finding on the assumptions level underpinning ED behaviors suggest that older adults do not belong in the ED, most older adults in the ED are not critically ill and therefore can wait, and staff need to be available for acute cases at all times. A systematic review on the effect of ED micro culture on the quality of geriatric care is warranted.

    This study explores the scope of practice of Obstetrics and Gynaecology specialists in Italy, Belgium and England, in light of the growth of professional and patient mobility within the EU which has raised concerns about a lack of standardisation of medical speciality practice and training. Semi-structured qualitative interviews were conducted with 29 obstetricians and gynaecologists from England, Belgium and Italy, exploring training and scope of practice, following a common topic guide. Interviews were recorded, transcribed and coded following a common coding framework in the language of the country concerned. Completed coding frames, written summaries and key quotes were then translated into English and were cross-analysed among the researchers to identify emerging themes and comparative findings. Although medical and specialty qualifications in each country are mutually recognised, there were great differences in training regimes, with different emphases on theory versus practice and recognition of different subspecialties. However all countries shared concerns about the impact of the European Working Time Directive on trainees' skills development. Reflecting differences in models of care, the scope of practice of OBGYN varied among countries, with pronounced differences between the public and private sector within countries. Technological advances and the growth of co-morbidities resulting from ageing populations have created new opportunities and greater links with other specialties. In turn new ethical concerns around abortion and fertility have also arisen, with stark cultural differences between the countries. Variations exist in the training and scope of practice of OBGYN specialists among these three countries, which could have significant implications for the expectations of patients seeking care and specialists practising in other EU countries. Changes within the specialty and advances in technology are creating new opportunities and challenges

    Full Text Available OBJECTIVES: Scientific knowledge can help develop interventions that improve public health. The objectives of this review are (1 to describe the status of research on knowledge transfer strategies in the field of complex social interventions in public health and (2 to identify priorities for future research in this field. METHOD: A scoping study is an exploratory study. After searching databases of bibliographic references and specialized periodicals, we summarized the relevant studies using a predetermined assessment framework. In-depth analysis focused on the following items: types of knowledge transfer strategies, fields of public health, types of publics, types of utilization, and types of research specifications. RESULTS: From the 1,374 references identified, we selected 26 studies. The strategies targeted mostly administrators of organizations and practitioners. The articles generally dealt with instrumental utilization and most often used qualitative methods. In general, the bias risk for the studies is high. CONCLUSION: Researchers need to consider the methodological challenges in this field of research in order to improve assessment of more complex knowledge transfer strategies (when they exist, not just diffusion/dissemination strategies and conceptual and persuasive utilization.

    2005-05-01

    Full Text Available Abstract Background There are currently several concerns about the ways in which people are recruited to participate in randomised controlled trials, the low acceptance rates among people invited to participate, and the experiences of trial participants. An information resource about on-going clinical trials designed for potential and current participants could help overcome some of these problems. Methods We carried out a scoping exercise to explore the desirability and feasibility of establishing such a resource. We sought the views of a range of people including people who were considering taking part in a trial, current trial participants, people who had been asked but refused to participate in a trial, consumer group representatives and researchers who design and conduct trials. Results There was broad-based support for the concept of a centralised information resource for members of the public about on-going and recently completed clinical trials. Such an information resource could be based on a database containing standardised information for each trial relating to the purpose of the trial; the interventions being compared; the implications of participation for participants; and features indicative of scientific quality and ethical probity. The usefulness of the database could be enhanced if its search facility could allow people to enter criteria such as a disease and geographic area and be presented with all the trials relevant to them, and if optional display formats could allow them to view information in varying levels of detail. Access via the Internet was considered desirable, with complementary supported access via health information services. The development of such a resource is technically feasible, but the collation of the required information would take a significant investment of resources. Conclusion A centralised participant oriented information resource about clinical trials could serve several purposes. A more detailed

    Full Text Available While agricultural practices are widely reported to contribute to anthropogenic greenhouse gas (GHG emissions, there are only limited measurements available for emission rates in the monsoon climate of the African continent. We conducted a scoping study to measure nitrous oxide (N2O-N and methane (CH4 emission rates from 24 plots constructed on smallholder agricultural farms along the slope catena of three transects in the sub-humid Anjeni watershed in the Ethiopian highlands. Greenhouse gas flux samples were collected in 2013, before, towards the end, and after the rainy monsoon phase. At each location, three plots were installed in groups: two plots grown with barley (one enriched with charcoal and the other without soil amendment and lupine was grown on the third plot without any soil amendment. Preliminary study results showed that nitrous oxide emission rates varied from −275 to 522 μg·m−2·h−1 and methane emissions ranged from −206 to 264 μg·m−2·h−1 with overall means of 51 and 5 μg·m−2·h−1 for N2O-N and CH4, respectively. Compared with the control, charcoal and lupine plots had elevated nitrous oxide emissions. Plots amended with charcoal showed on average greater methane uptake than was emitted. While this study provides insights regarding nitrous oxide and methane emission levels from smallholder farms, studies of longer durations are needed to verify the results.

    An identified barrier to the widespread use of renewable energy technologies (RET) is the (mis-) perception in the public, at a political level and within the industry sector about the benefits, opportunities and capabilities of RET. One reason is that the communication of the RE sector may not be convincing enough. In November 2011 IEA-RETD organised a workshop in Berlin that discussed the topics of 'sending clear messages', and 'getting the RE cost perception right'. One of the conclusions was that renewables need a better positioning, which could be achieved through improved communication. Therefore, IEA-RETD commissioned a scoping study with the objective to provide ideas, techniques and case studies on how the benefits of renewable energies can be better communicated to and by policy makers, decision makers and other stakeholders. The study concluded that more targeted, effective renewable energy communications campaigns can be achieved through the use of more consistent, holistic and rigorous approaches to pre- and post-campaign development.

    California agricultural irrigation consumes more than ten billion kilowatt hours of electricity annually and has significant potential for contributing to a reduction of stress on the grid through demand response, permanent load shifting, and energy efficiency measures. To understand this potential, a scoping study was initiated for the purpose of determining the associated opportunities, potential, and adoption challenges in California agricultural irrigation. The primary research for this study was conducted in two ways. First, data was gathered and parsed from published sources that shed light on where the best opportunities for load shifting and demand response lie within the agricultural irrigation sector. Secondly, a small limited survey was conducted as informal face-to-face interviews with several different California growers to get an idea of their ability and willingness to participate in permanent load shifting and/or demand response programs. Analysis of the data obtained from published sources and the survey reveal demand response and permanent load shifting opportunities by growing region, irrigation source, irrigation method, grower size, and utility coverage. The study examines some solutions for demand response and permanent load shifting in agricultural irrigation, which include adequate irrigation system capacity, automatic controls, variable frequency drives, and the contribution from energy efficiency measures. The study further examines the potential and challenges for grower acceptance of demand response and permanent load shifting in California agricultural irrigation. As part of the examination, the study considers to what extent permanent load shifting, which is already somewhat accepted within the agricultural sector, mitigates the need or benefit of demand response for agricultural irrigation. Recommendations for further study include studies on how to gain grower acceptance of demand response as well as other related studies such as

    To evaluate the performance of a broad scope model-based optimisation process for volumetric modulated arc therapy applied to esophageal cancer. A set of 70 previously treated patients in two different institutions, were selected to train a model for the prediction of dose-volume constraints. The model was built with a broad-scope purpose, aiming to be effective for different dose prescriptions and tumour localisations. It was validated on three groups of patients from the same institution and from another clinic not providing patients for the training phase. Comparison of the automated plans was done against reference cases given by the clinically accepted plans. Quantitative improvements (statistically significant for the majority of the analysed dose-volume parameters) were observed between the benchmark and the test plans. Of 624 dose-volume objectives assessed for plan evaluation, in 21 cases (3.3 %) the reference plans failed to respect the constraints while the model-based plans succeeded. Only in 3 cases (<0.5 %) the reference plans passed the criteria while the model-based failed. In 5.3 % of the cases both groups of plans failed and in the remaining cases both passed the tests. Plans were optimised using a broad scope knowledge-based model to determine the dose-volume constraints. The results showed dosimetric improvements when compared to the benchmark data. Particularly the plans optimised for patients from the third centre, not participating to the training, resulted in superior quality. The data suggests that the new engine is reliable and could encourage its application to clinical practice.

    Matching a person's capabilities and characteristics with the demands and characteristics of their job is crucial for sustainable employment, in particular for persons with disabilities. The present study aims to summarize and synthesize conceptual and empirical knowledge on job matching (JM) from industrial and organizational psychology (IOP), vocational psychology (VP), and return to work (RTW) research. We conducted a scoping study applying Arksey and O'Malley's (2005) framework and using eight electronic databases from psychology, economics, and medicine. The literature search covered studies in English and German published between 1945 and 2015. A total of 312 studies were selected and analyzed. Of these, 205 were assigned to IOP, 45 to VP, 31 to both IOP and VP, and 17 to RTW research. Fourteen studies were allocated to both RTW and VP research, representing the field of vocational rehabilitation counseling. IOP and VP studies predominantly investigated the effects of JM on work-related outcomes, such as job satisfaction, tenure, or career development. RTW research focused on the development of mainly generic JM tools for job placement of persons with disabilities. Limited cross-fertilization between IOP and VP and the RTW context became evident. Unlike in IOP and VP, there is a dearth of JM research in the RTW context. Integrating the broad organizational and occupational JM knowledge from IOP and VP with the biopsychosocial framework of RTW could provide a sound basis for developing JM applications in vocational rehabilitation counseling that promote sustainable work reintegration of persons with disabilities.

    This scoping study investigated how evidence-based practice (EBP) principles are taught in Australian speech-language pathology (SLP) teaching and learning contexts. It explored how Australian SLP university programs: (1) facilitate student learning about the principles of EBP in academic and clinical settings, and (2) self-evaluate their curricula in relation to EBP. The research involved two surveys. Survey 1 respondents were 131 academic staff, program coordinators, and on-campus and off-campus clinical educators. This survey gathered information about EBP teaching and learning in SLP programs as well as future EBP curriculum plans. Survey 2 investigated how clinical educators incorporated EBP into the way they taught clinical decision-making to students. Surveys responses from 85 clinical educators were analysed using descriptive and non-parametric statistics and thematic grouping of open-ended qualitative responses. Both surveys revealed strengths and gaps in integrating EBP into Australian SLP curricula. Perceived strengths were that respondents were positive about EBP, most had EBP training and access to EBP resources. The perceived gaps included the academic staff's perceptions of students' understanding and application of EBP, respondents' understanding of research methodologies, communication and collaboration between academic staff and clinical educators, and a lack of explicit discussion by clinical educators and students of EBP in relation to clients.

  7. Educational Strategies to Enhance Reflexivity Among Clinicians and Health Professional Students: A Scoping Study

    Full Text Available Reflexivity involves the ability to understand how one's social locations and experiences of advantage or disadvantage have shaped the way one understands the world. The capacity for reflexivity is crucial because it informs clinical decisions, which can lead to improvements in service delivery and patient outcomes. In this article, we present a scoping study that explored educational strategies designed to enhance reflexivity among clinicians and/or health profession students. We reviewed articles and grey literature that address the question: What is known about strategies for enhancing reflexivity among clinicians and students in health professional training programs? We searched multiple databases using keywords including: reflexivity, reflective, allied health professionals, pedagogy, learning, and education. The search strategy was iterative and involved three reviews. Each abstract was independently reviewed by two team members. Sixty-eight texts met the inclusion criteria. There was great diversity among the educational strategies and among health professions. Commonalities across strategies were identified related to reflective writing, experiential learning, classroom-based activities, continuing education, and online learning. We also summarize the 19 texts that evaluated educational strategies to enhance reflexivity. Further research and education is urgently needed for more equitable and socially-just health care.

    This scoping study focuses on the policy issues inherent in the claims made by some Smart Grid proponents that the demand response potential of mass market customers which is enabled by widespread implementation of Advanced Metering Infrastructure (AMI) through the Smart Grid could be the “silver bullet” for mitigating variable generation integration issues. In terms of approach, we will: identify key issues associated with integrating large amounts of variable generation into the bulk power system; identify demand response opportunities made more readily available to mass market customers through widespread deployment of AMI systems and how they can affect the bulk power system; assess the extent to which these mass market Demand Response (DR) opportunities can mitigate Variable Generation (VG) integration issues in the near-term and what electricity market structures and regulatory practices could be changed to further expand the ability for DR to mitigate VG integration issues over the long term; and provide a qualitative comparison of DR and other approaches to mitigate VG integration issues.

    This paper reports the findings of a scoping review on the organisation and delivery of health improvement activities in general practice and the primary healthcare team. The project was designed to examine who delivers these interventions, where they are located, what approaches are developed in practices and how individual practices and the primary healthcare team organise such public health activities and how these contribute to health improvement. Our focus was on health promotion and prevention activities and aimed to identify the current extent of knowledge about the health improvement activities in general practice and the wider primary healthcare team. Many of the research studies reviewed had some details about the type, process, location or who provided the intervention. Little attention is paid in the literature to examining the impact of the organisational context on the way services are delivered or how this affects the effectiveness of health improvement interventions in general practice. We found that the focus of attention is mainly on individual prevention approaches with practices engaging in both primary and secondary prevention. Although many GPs do not take a population approach and focus on individual patients some do see health promotion as an integral part of practice - whether as individual approaches to primary or secondary health improvement or as a practice-based approach to improving the health of their patients. Based on our analysis we conclude that there is insufficient good evidence to support many of the health improvement interventions undertaken in general practice and primary care.

  10. The application of evolutionary medicine principles for sustainable malaria control: a scoping study.

    2016-07-22

    Current interventions against malaria have significantly reduced the number of people infected and the number of deaths. Concerns about emerging resistance of both mosquitoes and parasites to intervention have been raised, and questions remain about how best to generate wider knowledge of the underlying evolutionary processes. The pedagogical and research principles of evolutionary medicine may provide an answer to this problem. Eight programme managers and five academic researchers were interviewed by telephone or videoconference to elicit their first-hand views and experiences of malaria control given that evolution is a constant threat to sustainable control. Interviewees were asked about their views on the relationship between practit groups and academics and for their thoughts on whether or not evolutionary medicine may provide a solution to reported tensions. There was broad agreement that evolution of both parasites and vectors presents an obstacle to sustainable control. It was also widely agreed that through more efficient monitoring, evolution could be widely monitored. Interviewees also expressed the view that even well planned interventions may fail if the evolutionary biology of the disease is not considered, potentially making current tools redundant. This scoping study suggests that it is important to make research, including evolutionary principles, available and easily applicable for programme managers and key decision-makers, including donors and politicians. The main conclusion is that sharing knowledge through the educational and research processes embedded within evolutionary medicine has potential to relieve tensions and facilitate sustainable control of malaria and other parasitic infections.

    This paper describes the methods, strategies and insights gained from a scoping study using a "Two-Eyed Seeing" approach. An evolving technique, Two-Eyed Seeing respects and integrates the strengths of Indigenous knowledge and Western sciences, often "weaving back and forth" between the two worldviews. The scoping study was used to inform a tool for measuring the impact of culturally based addictions treatment services on wellness in Indigenous populations. It formed part of a three-year study, Honouring Our Strengths: Indigenous Culture as Intervention in Addictions Treatment. The scoping study identified and mapped literature on cultural interventions in addictions treatment, and described the nature, extent and gaps in literature. Using a Two-Eyed Seeing approach, we adapted, applied and enhanced a common framework of scoping studies. In the end stage of the scoping review process, an Ad Hoc Review Group, led by our project Elder, reviewed and interpreted Indigenous and Western understandings within the mapped information. Elements of the scoping study were joined with results from community focus groups with staff at treatment centres. Two-Eyed Seeing contributed differently at each stage of the scoping study. In early stages, it clarified team expertise and potential contributions. At the mid-point, it influenced our shift from a systematic to a scoping review. Near the end, it incorporated Western and Indigenous knowledge to interpret and synthesize evidence from multiple sources. This paper adds to the collective work on augmenting the methodology of scoping studies. Despite the challenges of a Two-Eyed Seeing approach, it enables researchers using scoping studies to develop knowledge that is better able to translate into meaningful findings for Indigenous communities.

    Despite countries' efforts to ensure access to essential medicines, some people do not have their needs met, and often resort to the Judiciary to get access to the medicines they need. This phenomenon, known as "judicialization of access to medicines", has aroused the academia's interest in law, health and social fields. In this context, this scoping study investigates, through qualitative thematic analysis, the approach to judicialization of access to medicines (normative or social) and its possible impacts (positive or negative) described in articles published in scientific journals indexed in the main health databases prior to July 2012. 65 of 384 papers met the inclusion criteria of focusing on lawsuits for access to medicines or judicialization of access to medicines as a phenomenon; empiric studies, review articles or theoretical discussions, written in English, Portuguese or Spanish; most of them were about Brazil, Colombia and England. Results show that judicialization is a complex phenomenon that involves technical-scientific, legal and social aspects. The judicialization impacts mentioned have changed over time. In the late 1990s and early 2000s the emphasis of positive impacts predominated both on the normative and social approaches, having as main reference the movements that claimed from the States the guarantee of access to HIV/AIDS treatment. In the mid-2000s, however, there was an emphasis of the negative effects of judicial intervention, when lawsuits for access to medicines became a problem in some countries. Few studies used the social approach to judicialization. For this reason, there is not enough information about whether lawsuits for access to medicines are related to a real recognition of the right to health as an exercise of citizenship. Such aspects need to be further studied.

    Objective To assess scientific publication and map research gaps on access to medicines (ATM) in Latin American and the Caribbean low-income and middle-income countries (LMIC). Design Scoping review. Two independent reviewers assessed studies for inclusion and extracted data from each study. Information sources Search strategies were developed and the following databases were searched: MEDLINE, ISI, SCOPUS and Lilacs, from 2000 to 2010. Eligibility criteria Research articles and reviews published in English, Spanish and Portuguese were included. Studies including only high-income countries were excluded, as well as those carried out in very limited settings and discussion papers. Results The 77 articles retained were categorised through consensus among the research team according to the level of the health system addressed, ATM domain and research issues covered. Publications on ATM have increased over time during the study period (r 0.93, p=0.00; R2 0.85). The top five countries covered were Brazil (68.8%), Mexico (15.6%), Colombia (11.7%), Argentina (10.4%) and Peru (10.4%). ‘Health services delivery’ and ‘patients, household and communities’ were the health system levels most frequently covered. The ATM domains ‘leadership and governance’, ‘sustainable financing, affordability and price of medicines’, ‘medicines selection and use’ and ‘availability of medicines’ were the top four explored. There are research gaps in important areas such as ‘human resources for health’, ‘global policies and human rights’, ‘production of medicines’ and ‘traditional medicine’. Conclusions The upward trend on scientific publication reflects a growing research capacity in the region, which is concentrated on research teams in selected countries. The gaps on research capacity could be overcome through research collaboration among countries. It is important to strengthen these collaborations, assuring that interests and needs from the LMIC are

    South Asian (SA) immigrants settled in the United Kingdom (UK) and North America [United States (US) and Canada] have low screening rates for breast, cervical and colorectal cancers. Incidence rates of these cancers increase among SA immigrants after migration, becoming similar to rates in non-Asian native populations. However, there are disparities in cancer screening, with low cancer screening uptake in this population. We conducted a scoping study using Arksey & O'Malley's framework to examine cancer screening literature on SA immigrants residing in the UK, US and Canada. Eight electronic databases, key journals and reference lists were searched for English language studies and reports. Of 1465 identified references, 70 studies from 1994 to November 2014 were included: 63% on breast or cervical cancer screening or both; 10% examined colorectal cancer screening only; 16% explored health promotion/service provision; 8% studied breast, cervical and colorectal cancer screening; and 3% examined breast and colorectal cancer screening. A thematic analysis uncovered four dominant themes: (i) beliefs and attitudes towards cancer and screening included centrality of family, holistic healthcare, fatalism, screening as unnecessary and emotion-laden perceptions; (ii) lack of knowledge of cancer and screening related to not having heard about cancer and its causes, or lack of awareness of screening, its rationale and/or how to access services; (iii) barriers to access including individual and structural barriers; and (iv) gender differences in screening uptake and their associated factors. Findings offer insights that can be used to develop culturally sensitive interventions to minimise barriers and increase cancer screening uptake in these communities, while recognising the diversity within the SA culture. Further research is required to address the gap in colorectal cancer screening literature to more fully understand SA immigrants' perspectives, as well as research to

  18. Improving Natural Uranium Utilization By Using Thorium in Low Moderation PWRs - A Preliminary Neutronic Scoping Study

    Energy Technology Data Exchange (ETDEWEB)

    Gilles Youinou; Ignacio Somoza

    2010-10-01

    The Th-U fuel cycle is not quite self-sustainable when used in water-cooled reactors and with fuel burnups higher than a few thousand of MWd/t characteristic of CANDU reactors operating with a continuous refueling. For the other industrially mature water-cooled reactors (i.e. PWRs and BWRs) it is economically necessary that the fuel has enough reactivity to reach fuel burnups of the order of a few tens of thousand of MWd/t. In this particular case, an additional input of fissile material is necessary to complement the bred fissile U-233. This additional fissile material could be included in the form of Highly Enriched Uranium (HEU) at the fabrication of the Th-U fuel. The objective of this preliminary neutronic scoping study is to determine (1) how much HEU and, consequently, how much natural uranium is necessary in such Th-U fuel cycle with U recycling and (2) how much TRansUranics (TRU=Pu, Np, Am and Cm) are produced. These numbers are then compared with those of a standard UO2 PWR. The thorium reactors considered have a homogeneous hexagonal lattice made up of the same (Th-U)O2 pins. Furthermore, at this point, we are not considering the use of blankets inside or outside the core. The lattice pitch has been varied to estimate the effect of the water-to-fuel volume ratio, and light water as well as heavy water have been considered. For most cases, an average burnup at discharge of 45,000 MWd/t has been considered.

    2014-01-01

    Aim To describe the training, supervision and quality of care components of integrated Community Case Management (iCCM) programmes and to draw lessons learned from existing evaluations of those programmes. Methods Scoping review of reports from 29 selected iCCM programmes purposively provided by stakeholders containing any information relevant to understand quality of care issues. Results The number of people reached by iCCM programmes varied from the tens of thousands to more than a million. All programmes aimed at improving access of vulnerable populations to health care, focusing on the main childhood illnesses, managed by Community Health Workers (CHW), often selected bycommunities. Training and supervision were widely implemented, in different ways and intensities, and often complemented with tools (eg, guides, job aids), supplies, equipment and incentives. Quality of care was measured using many outcomes (eg, access or appropriate treatment). Overall, there seemed to be positive effects for those strategies that involved policy change, organisational change, standardisation of clinical practices and alignment with other programmes. Positive effects were mostly achieved in large multi–component programmes. Mild or no effects have been described on mortality reduction amongst the few programmes for which data on this outcome was available to us. Promising strategies included teaming–up of CHW, micro–franchising or social franchising. On–site training and supervision of CHW have been shown to improve clinical practices. Effects on caregivers seemed positive, with increases in knowledge, care seeking behaviour, or caregivers’ basic disease management. Evidence on iCCM is often of low quality, cannot relate specific interventions or the ways they are implemented with outcomes and lacks standardisation; this limits the capacity to identify promising strategies to improve quality of care. Conclusion Large, multi–faceted, iCCM programmes, with strong

    Speroff, Theodore; O'Connor, Gerald T

    2004-01-01

    The purpose of this article is to discuss strengths and weaknesses of quasi-experimental designs used in health care quality improvement research. The target groups for this article are investigators in plan-do-study-act (PDSA) quality improvement initiatives who wish to improve the rigor of their methodology and publish their work and reviewers who evaluate the quality of research proposals or published work. A primary purpose of PDSA quality improvement research is to establish a functional relationship between process changes in systems of health care and variation in outcomes. The time series design is the fundamental paradigm for demonstrating such functional relationships. The rigor of a PDSA quality improvement study design is strengthened using replication schemes and research methodology to address extraneous factors that weaken validity of observational studies. The design of PDSA quality improvement research should follow from the purpose and context of the project. Improving the rigor of the quality improvement literature will build a stronger foundation and more convincing justification for the study and practice of quality improvement in health care.

    Objectives The aim of our scoping review was to identify and summarize current evidence on the biomechanics of fencing to inform athlete development and injury prevention. Design Scoping review. Method Peer-reviewed research was identified from electronic databases using a structured keyword search. Details regarding experimental design, study group characteristics and measured outcomes were extracted from retrieved studies, summarized and information regrouped under themes for analysis. The methodological quality of the evidence was evaluated. Results Thirty-seven peer-reviewed studies were retrieved, the majority being observational studies conducted with experienced and elite athletes. The methodological quality of the evidence was “fair” due to the limited scope of research. Male fencers were the prevalent group studied, with the lunge and use of a foil weapon being the principal movement evaluated. Motion capture and pedabarography were the most frequently used data collection techniques. Conclusions Elite fencers exhibited sequential coordination of upper and lower limb movements with coherent patterns of muscle activation, compared to novice fencers. These elite features of neuromuscular coordination resulted in higher magnitudes of forward linear velocity of the body center of mass and weapon. Training should focus on explosive power. Sex- and equipment-specific effects could not be evaluated based on available research. PMID:28187164

    2015-02-01

    Little research has been undertaken on how infection prevention and control (IPC) teams operate and how their effectiveness is assessed. This review aimed to explore how IPC teams embed IPC throughout hospitals, balance outbreak management with strategic aspects of IPC work (e.g. education), and how IPC team performance is measured. A scoping exercise was performed combining literature searches, evidence synthesis, and intelligence from expert advisers. Eleven publications were identified. One paper quantified how IPC nurses spend their time, two described daily activities of IPC teams, five described initiatives to embed IPC across organizations following legislation since 1999 in the UK or changes in the delivery of healthcare, and three explored the contribution of IPC intermediaries (link nurses and champions). Eight publications reported research findings. The others reported how IPC teams are embedding IPC practice in UK hospitals. In conclusion, there is scope for research to explore different models of IPC team-working and effectiveness, and cost-effectiveness. Other topics that need addressing are the willingness and ability of ward staff to assume increased responsibility for IPC and the effectiveness of intermediaries.

    α-Quaternary ketones are accessed through novel enantioselective alkylations of allyl and propargyl electrophiles by unstabilized prochiral enolate nucleophiles in the presence of palladium complexes with various phosphinooxazoline (PHOX) ligands. Excellent yields and high enantiomeric excesses are obtained from three classes of enolate precursor: enol carbonates, enol silanes, and racemic β-ketoesters. Each of these substrate classes functions with nearly identical efficiency in terms of yield and enantioselectivity. Catalyst discovery and development, the optimization of reaction conditions, the exploration of reaction scope, and applications in target-directed synthesis are reported. Experimental observations suggest that these alkylation reactions occur through an unusual inner-sphere mechanism involving binding of the prochiral enolate nucleophile directly to the palladium center.

    The efficiency and effectivity of the learning experience is dependent on the teacher quality, thus, enhancing teacher's quality is vital in improving the students learning outcome. Since, the usual top-down one-shot cascading model practice for teachers' professional development in Philippines has been observed to have much information dilution, and the Southeast Asian Ministers of Education Organization demanded the need to develop mathematics teachers' quality standards through the Southeast Asia Regional Standards for Mathematics Teachers (SEARS-MT), thus, an intensive, ongoing professional development model should be provided to teachers. This study was undertaken to determine the impact of Lesson Study on Bulua National High School mathematics teachers' quality level in terms of SEARS-MT dimensions. A mixed method of quantitative-qualitative research design was employed. Results of the analysis revealed that Lesson Study effectively enhanced mathematics teachers' quality and promoted teachers professional development. Teachers positively perceived Lesson Study to be beneficial for them to become a better mathematics teacher.

    The merits of mixed public and private health systems are debated. Although private providers have become increasingly important in the Indonesian health system, there is no comprehensive assessment of the quality of private facilities. This study examined the quality of physical resources of public and private facilities in Indonesia from 1993 to 2007. Data from the Indonesian Family Life Surveys in 1993, 1997, 2000 and 2007 were used to evaluate trends in the quality of physical resources for public and private facilities, stratified by urban/rural areas and Java-Bali/outer Java-Bali regions. The quality of six categories of resources was measured using an adapted MEASURE Evaluation framework. Overall quality was moderate, but higher in public than in private health facilities in all years regardless of the region. The higher proportion of nurses and midwives in private practice was a determinant of scope of services and facilities available. There was little improvement in quality of physical resources following decentralization. Despite significant increases in public investment in health between 2000 and 2006 and the potential benefits of decentralization (2001), the quality of both public and private health facilities in Indonesia did not improve significantly between 1993 and 2007. As consumers commonly believe the quality is better in private facilities and are increasingly using them, it is essential to improve quality in both private and public facilities. Implementation of minimum standards and effective partnerships with private practice are considered important.

    California is on a path to increase utilization of renewable resources. California will need to integrate approximately 30,000 megawatts (MW) of new renewable generation in the next 20 years. Renewable resources are typically located in remote locations, not near the load centers. Nearly two/thirds or 20,000 MW of new renewable resources needed are likely to be delivered to Los Angeles Basin transmission gateways. Integration of renewable resources requires interconnection to the power grid, expansion of the transmission system capability between the backbone power grid and transmission gateways, and increase in delivery capacity from transmission gateways to the local load centers. To scope the transmission, operations, and reliability issues for renewables integration, this research focused on the Los Angeles Basin Area transmission gateways where most of new renewables are likely. Necessary actions for successful renewables integration include: (1) Expand Los Angeles Basin Area transmission gateway and nomogram limits by 10,000 to 20,000 MW; (2) Upgrade local transmission network for deliverability to load centers; (3) Secure additional storage, demand management, automatic load control, dynamic pricing, and other resources that meet regulation and ramping needed in real time operations; (4) Enhance local voltage support; and (5) Expand deliverability from Los Angeles to San Diego and Northern California.

    This study utilized data from Focus Group Discussions and In-depth Interviews among secondary school students and teachers to examine the scope, delivery and challenges of FLHE implementation within states and across geopolitical zones in Nigeria. Structural Functionalism, Rational Choice and Differential Association theories were adopted as theoretical framework. Results show that several patterns in classroom teaching of FLHE are identifiable across the country. The study found that FLHE is taught at the Junior Secondary and Senior Secondary levels with variations among States on the beginning levels. The main mode of FLHE delivery is classroom instruction; other modes include assembly talk and sensitization by organizations. Despite paucity of Information, Education and Communication materials and inadequate personnel requirement, different stakeholders noted that FLHE has been beneficial to students. Therefore, effective implementation of FLHE will go a long way to ensuring that young people in Nigeria are equipped with necessary information to enable them exhibit the right attitude and behaviour towards sexuality issues.

    The study's purpose was to describe the range of knowledge pertaining to the Bobath (NDT) concept in adult neurological rehabilitation, synthesizes the findings, identify knowledge gaps and develop empirically based recommendations for future research. A scoping review of research and non-research articles published from 2007 to 2012. Two independent reviewers selected studies based on a systematic procedure. Inclusion criteria for studies were electronically accessible English language literature with Bobath and/or Neurodevelopmental Therapy as the subject heading in the title/keyword/abstract/intervention comparison with respect to adult neurological conditions. Data were abstracted and summarized with respect to study design, theoretical framework, clinical application including population representation, study fidelity, intervention comparison, duration of care, measurement and findings. Of the 33 publications identified 17 were intervention studies (11 RCT's/1 prospective parallel group design/5 N-of-1). One other paper was a systematic review. The intervention studies, primarily RCT designs, have serious methodological concerns particularly related to study/treatment fidelity and measurement resulting in no clear clinical direction. Aspects such as theoretical framework, therapist skill, quality of movement measurement and individualized interventions require careful consideration in the design of Bobath studies. Implications for Rehabilitation Future intervention studies should be based on the current Bobath theoretical framework and key aspects of clinical practice. Study and treatment fidelity issues need to be carefully considered when interpreting the results of existing RCT's evaluating the Bobath concept. N-of-1 randomized, observational, factorial and mixed method study designs should be considered as alternative study options.

    Mexico City Metropolitan Area has been the object of several well know intensive campaigns. Since MARI (1991) , IMADA (1997), MCMA 2003 and MILAGRO (2006). The spatial scope of these studies have gone from urban to regional to continental, with the focus on MCMA as an emissions source. During MILAGRO, the influence on MCMA of wildfires and agricultural biomass burning around the megacity was considered. However, around Mexico City a crown of metropolis and middle size cities make a region known as the Central Mexico Regional Crow (CRCM for its acronym in Spanish language) or Central Mexico City Belt. It contains 32 million inhabitants and produces 40% of national gross product. The region undergoes an uncontrolled urban sprawl. Evidence is building-up on complex air pollution transport processes between the air basins within CRCM. However, only MCMA counts with reliable long-term records of criteria pollutants monitoring. Only few intensive campaigns have been done in the air basins surrounding MCMA. ECAIM project has several goals: a) To use ground and satellite observations to assess emissions inventories; b) To use ground and satellite observations to assess the performance of air quality models for the whole region; c) to produce critical levels exceedence maps; d) To produce a preliminary diagnostic of air quality for the CRCM; e) to produce a preliminary estimate of the cost of air pollution within the CRCM. In this work we show the method approach to use the best available information from local AQM networks, field campaigns, satellite observations and modeling to achieve those goals. We show some preliminary results.

    The aim of this review was to investigate the quality of the current literature on the transfer of anticonvulsants to breast milk to provide an overview of which anticonvulsants are in need of further research. We reviewed the quality of the available lactation studies for 19 anticonvulsants against the guidelines of the Food and Drug Administration (FDA) and the International Lactation Consultant Association (ILCA). Except for one study on lamotrigine and one case report on gabapentin, no study on anticonvulsants had both the absolute infant dose (AID) and milk to plasma ratio (M : P) correctly assessed. Only one study on carbamazepine, phenytoin and vigabatrin was found that correctly assessed the AID. The main cause for this low number is the lack of essential details in published studies, since 25 of 62 studies were case reports, letters or abstracts. Other major shortcomings were the lack of information on sampling methods, the number of samples in a particular dose interval as well as the low number of study participants. The quality of the current literature on the transfer of anticonvulsants to breast milk is low, except for lamotrigine, which makes it hard to draw conclusions about the safety of the use of anticonvulsants during the lactation period. Therefore, further research is needed. © 2014 The British Pharmacological Society.

    Full Text Available Nowadays, drug research and surveillance after authorisation becomes more and more important for several reasons. Non-interventional studies (NIS investigate various aspects of drug use including efficacy and safety under real life conditions. Such kind of health services research should be on a high scientific, methodological and organisational level. Therefore accompanying measures to improve or to keep the quality are highly recommended. The aim of quality management is: first to avoid bias of results by using an appropriate study design and an adequate data analysis, second to assure authenticity, completeness and validity of the data and third to identify and resolve deficiencies at an early stage. Basic principles are laid down in corresponding guidelines and recommendations of authorities, institutes and societies. Various guidelines for good epidemiological practice (GEP were published by the U.S. Food and Drug Administration (FDA and international and regional societies for epidemiology. In addition in Germany the Federal Institute for Drugs and Medical Devices (BfArM together with the Paul Ehrlich Institute (PEI and the German Association of Research-Based Pharmaceutical Companies (VFA have published respectively recommendations dealing with quality aspects of non-interventional observational studies. Key points are the advanced publishing of information about the project, developing of a study plan/protocol containing the scientific objectives, a sample size justification and a description of the planned analyses and the publishing of a summary of the results timely after completion of the study. The quality of the data can be improved by using standardized case report forms (CRF and the CRF should be reviewed and tested before start of study by some participants. A source data verification (SDV should be performed in randomly selected centres – in between 2% and 5% of the centres depending on the number of participating centres

    Tungsten-halogen (halogen) lamps have traditionally been used to light surgical tasks in hospitals, even though they are in many respects ill-suited to the application due to the large percentage of radiant energy outside the visible spectrum and issues with color rendering/quality. Light-emitting diode (LED) technology offers potential for adjustable color and improved color rendition/quality, while simultaneously reducing side-effects from non-visible radiant energy. It also has the potential for significant energy savings, although this is a fairly narrow application in the larger commercial building energy use sector. Based on analysis of available products and Hospital Energy Alliance member interest, it is recommended that a product specification and field measurement procedure be developed for implementation in demonstration projects.

    Full Text Available A high quality of work life (QWL is essential for organizations to continue to attract and retain employees. QWL is a comprehensive program designated to improve employee satisfaction. This research aimed to provide insights into the positive and negative attitudes of Tehran University of Medical Sciences (TUMS Hospitals’ employees from their quality of life. A cross- sectional, descriptive and analytical study was conducted among 908 TUMS hospitals’ employees by questionnaire at 15 studied hospitals. A stratified random sampling technique was used to select respondents as nursing, supportive and paramedical groups. The results showed that the majority of employees were dissatisfied with occupational health and safety, intermediate and senior managers , their income, balance between the time they spent working and with family and also indicated that their work was not interesting and satisfying. TUMS hospitals’ employees responding to this survey have a poor quality of work life. We suggest more training and educations for TUMS hospitals’ managers on QWL issues are planned.

    Full Text Available Background. In this pilot study, we evaluated tip collisions against three commonly used measures of fibreoptic scope handling skills. Methods. Seventy-seven anaesthetists were recruited to perform a standardized task on an Oxford Box and a modified AirSim manikin. Collision count was correlated against time to scope placement, a global rating scale score, and up-to-date fibreoptic experience. Results. Strong and moderate correlations were found between collision count and task completion time for the Oxford Box (ρ = 0.730, P < 0.0001 and AirSim manikin (ρ = 0.405, P < 0.0001, respectively. Moderate correlation was found between collision count and global rating scale score for the Oxford Box (ρ = −0.545, P < 0.0001 and AirSim manikin (ρ = −0.500, P < 0.0001. Mild and moderate correlations were found between collision count and fibreoptic experience on the Oxford Box (ρ = −0.240, P = 0.041 and AirSim manikin (ρ = −0.423, P < 0.0001, respectively. Conclusions. This study infers that collision count may be used as a measure of fibreoptic scope handling skills in simulation training. Using this outcome in addition to other measures of performance may improve accuracy and precision of fibreoptic scope placement.

    Air quality and meteorological data collected at Fermi National Accelerator Laboratory are presented. The data represent baseline values for the pre-construction phase of a proposed coal-gasification test facility. Air quality data were characterized through continuous monitoring of gaseous pollutants, collection of meteorological data, data acquisition and reduction, and collection and analysis of discrete atmospheric samples. Seven air quality parameters were monitored and recorded on a continuous real-time basis: sulfur dioxide, ozone, total hydrocarbons, nonreactive hydrocarbons, nitric oxide, nitrogen oxides, and carbon monoxide. A 20.9-m tower was erected near Argonne's mobile air monitoring laboratory, which was located immediately downwind of the proposed facility. The tower was instrumented at three levels to collect continuous meteorological data. Wind speed was monitored at three levels; wind direction, horizontal and vertical, at the top level; ambient temperature at the top level; and differential temperature between all three levels. All continuously-monitored parameters were digitized and recorded on magnetic tape. Appropriate software was prepared to reduce the data. Statistical summaries, grphical displays, and correlation studies also are presented.

    2016-11-07

    Recruiting an adequate number of participants into medical research studies is challenging for many researchers. Over the past 10 years, the use of social media websites has increased in the general population. Consequently, social media websites are a new, powerful method for recruiting participants into such studies. The objective was to answer the following questions: (1) Is the use of social media more effective at research participant recruitment than traditional methods? (2) Does social media recruit a sample of research participants comparable to that recruited via other methods? (3) Is social media more cost-effective at research participant recruitment than traditional methods? Using the MEDLINE, PsycINFO, and EMBASE databases, all medical research studies that used social media and at least one other method for recruitment were identified. These studies were then categorized as either interventional studies or observational studies. For each study, the effectiveness of recruitment, demographic characteristics of the participants, and cost-effectiveness of recruitment using social media were evaluated and compared with that of the other methods used. The social media sites used in recruitment were identified, and if a study stated that the target population was "difficult to reach" as identified by the authors of the study, this was noted. Out of 30 studies, 12 found social media to be the most effective recruitment method, 15 did not, and 3 found social media to be equally effective as another recruitment method. Of the 12 studies that found social media to be the best recruitment method, 8 were observational studies while 4 were interventional studies. Of the 15 studies that did not find social media to be the best recruitment method, 7 were interventional studies while 8 were observational studies. In total, 8 studies stated that the target population was "hard-to-reach," and 6 of these studies found social media to be the most effective recruitment

    Human biospecimens are subjected to collection, processing, and storage that can significantly alter their molecular composition and consistency. These biospecimen preanalytical factors, in turn, influence experimental outcomes and the ability to reproduce scientific results. Currently, the extent and type of information specific to the biospecimen preanalytical conditions reported in scientific publications and regulatory submissions varies widely. To improve the quality of research that uses human tissues, it is crucial that information on the handling of biospecimens be reported in a thorough, accurate, and standardized manner. The Biospecimen Reporting for Improved Study Quality (BRISQ) recommendations outlined herein are intended to apply to any study in which human biospecimens are used. The purpose of reporting these details is to supply others, from researchers to regulators, with more consistent and standardized information to better evaluate, interpret, compare, and reproduce the experimental results. The BRISQ guidelines are proposed as an important and timely resource tool to strengthen communication and publications on biospecimen-related research and to help reassure patient contributors and the advocacy community that their contributions are valued and respected.

    A fuel quality processing study to provide a data base for an intelligent tradeoff between advanced turbine technology and liquid fuel quality, and also, to guide the development of specifications of future synthetic fuels anticipated for use in the time period 1985 to 2000 is given. Four technical performance tests are discussed: on-site pretreating, existing refineries to upgrade fuels, new refineries to upgrade fuels, and data evaluation. The base case refinery is a modern Midwest refinery processing 200,000 BPD of a 60/40 domestic/import petroleum crude mix. The synthetic crudes used for upgrading to marketable products and turbine fuel are shale oil and coal liquids. Of these syncrudes, 50,000 BPD are processed in the existing petroleum refinery, requiring additional process units and reducing petroleum feed, and in a new refinery designed for processing each syncrude to produce gasoline, distillate fuels, resid fuels, and turbine fuel, JPGs and coke. An extensive collection of synfuel properties and upgrading data was prepared for the application of a linear program model to investigate the most economical production slate meeting petroleum product specifications and turbine fuels of various quality grades. Technical and economic projections were developed for 36 scenarios, based on 4 different crude feeds to either modified existing or new refineries operated in 2 different modes to produce 7 differing grades of turbine fuels. A required product selling price of turbine fuel for each processing route was calculated. Procedures and projected economics were developed for on-site treatment of turbine fuel to meet limitations of impurities and emission of pollutants.

    BACKGROUND There is growing interest in starting a program to sink ships in Puget Sound to create one or more underwater dive sites. Experience in other parts of the world has indicated that sunken vessels are highly popular with divers and could provide a basis for increased recreation and attraction of out-of-state divers with attendant economic benefits to the State. The Washington State legislature reviewed this possibility during the 2006 session and determined that more information is required before the legislature could determine if this activity is feasible or desirable. The legislature directed several State agencies to undertake a preliminary study of the feasibility. The Washington Department of Fish and Wildlife (WDFW, lead State agency) in turn asked U.S. Geological Survey to conduct the study.

  5. Physical Impacts of Climate Change on the Western US Electricity System: A Scoping Study

    Coughlin, Katie; Goldman, Charles

    2008-12-01

    This paper presents an exploratory study of the possible physical impacts of climate change on the electric power system, and how these impacts could be incorporated into resource planning in the Western United States. While many aspects of climate change and energy have been discussed in the literature, there has not yet been a systematic review of the relationship between specific physical effects and the quantitative analyses that are commonly used in planning studies. The core of the problem is to understand how the electric system is vulnerable to physical weather risk, and how to make use of information from climate models to characterize the way these risks may evolve over time, including a treatment of uncertainty. In this paper, to provide the necessary technical background in climate science, we present an overview of the basic physics of climate and explain some of the methodologies used in climate modeling studies, particularly the importance of emissions scenarios. We also provide a brief survey of recent climate-related studies relevant to electric system planning in the Western US. To define the institutional context, we discuss the core elements of the resource and reliability planning processes used currently by utilities and by the Western Electricity Coordinating Council. To illustrate more precisely how climate-related risk could be incorporated into modeling exercises, we discuss three idealized examples. Overall, we argue that existing methods of analysis can and should be extended to encompass the uncertainties related to future climate. While the focus here is on risk related to physical impacts, the same principles apply to a consideration of how future climate change policy decisions might impact the design and functioning of the electric grid. We conclude with some suggestions and recommendations on how to begin developing this approach within the existing electric system planning framework for the West.

    The Advanced Test Reactor (ATR), under the Reduced Enrichment for Research and Test Reactors (RERTR) Program and the Global Threat Reduction Initiative (GTRI), is conducting feasibility studies for the conversion of its fuel from a highly enriched uranium (HEU) composition to a low enriched uranium (LEU) composition. These studies have considered a wide variety of LEU plate-type fuels to replace the current HEU fuel. Continuing to investigate potential alternatives to the present HEU fuel form, this study presents a preliminary analysis of TRIGA® fuel within the current ATR fuel envelopes and compares it to the functional requirements delineated by the Naval Reactors Program, which includes: greater than 4.8E+14 fissions/s/g of 235U, a fast to thermal neutron flux ratio that is less than 5% deviation of its current value, a constant cycle power within the corner lobes, and an operational cycle length of 56 days at 120 MW. Other parameters outside those put forth by the Naval Reactors Program which are investigated herein include axial and radial power profiles, effective delayed neutron fraction, and mean neutron generation time.

    Budding yeast, S. cerevisiae, has been used extensively as a model organism for studying cellular processes in evolutionarily distant species, including humans. However, different human tissues, while inheriting a similar genetic code, exhibit distinct anatomical and physiological properties. Specific biochemical processes and associated biomolecules that differentiate various tissues are not completely understood, neither is the extent to which a unicellular organism, such as yeast, can be used to model these processes within each tissue. We present a novel framework to systematically quantify the suitability of yeast as a model organism for different human tissues. To this end, we develop a computational method for dissecting the global human interactome into tissue-specific cellular networks. By individually aligning these networks with the yeast interactome, we simultaneously partition the functional space of human genes, and their corresponding pathways, based on their conservation both across species and among different tissues. Finally, we couple our framework with a novel statistical model to assess the conservation of tissue-specific pathways and infer the overall similarity of each tissue with yeast. We further study each of these subspaces in detail, and shed light on their unique biological roles in the human tissues. Our framework provides a novel tool that can be used to assess the suitability of the yeast model for studying tissue-specific physiology and pathophysiology in humans. Many complex disorders are driven by a coupling of housekeeping (universally expressed in all tissues) and tissue-selective (expressed only in specific tissues) dysregulated pathways. While tissue-selective genes are significantly associated with the onset and development of a number of tissue-specific pathologies, we show that the human-specific subset has even higher association. Consequently, they provide excellent candidates as drug targets for therapeutic interventions.

  8. The cost of child health inequalities in Aotearoa New Zealand: a preliminary scoping study

    Full Text Available Abstract Background Health inequalities have been extensively documented, internationally and in New Zealand. The cost of reducing health inequities is often perceived as high; however, recent international studies suggest the cost of “doing nothing” is itself significant. This study aimed to develop a preliminary estimate of the economic cost of health inequities between Māori (indigenous and non-Māori children in New Zealand. Methods Standard quantitative epidemiological methods and “cost of illness” methodology were employed, within a Kaupapa Māori theoretical framework. Data were obtained from national data collections held by the New Zealand Health Information Service and other health sector agencies. Results Preliminary estimates suggest child health inequities between Māori and non-Māori in New Zealand are cost-saving to the health sector. However the societal costs are significant. A conservative “base case” scenario estimate is over $NZ62 million per year, while alternative costing methods yield larger costs of nearly $NZ200 million per annum. The total cost estimate is highly sensitive to the costing method used and Value of Statistical Life applied, as the cost of potentially avoidable deaths of Māori children is the major contributor to this estimate. Conclusions This preliminary study suggests that health sector spending is skewed towards non-Māori children despite evidence of greater Māori need. Persistent child health inequities result in significant societal economic costs. Eliminating child health inequities, particularly in primary care access, could result in significant economic benefits for New Zealand. However, there are conceptual, ethical and methodological challenges in estimating the economic cost of child health inequities. Re-thinking of traditional economic frameworks and development of more appropriate methodologies is required.

  9. Scoping Adaptation Needs for Smallholders in the Brazilian Amazon: A Municipal Level Case Study

    Full Text Available Over the past decade, several climate extreme events have caused considerable economic damage and hardship in the Brazilian Amazon region, especially for small-scale producers. Based on household surveys and focus group interviews in the Municipality of Alenquer as well as secondary data analyses and a literature review at the regional level, this study seeks to assess rural small-scale producers’ vulnerability to climate and non-climate related shocks and identify entry points for government action to support adaptation at the local level. In our case study area, small-scale producers with similar wealth, self-sufficiency, and resource use specialisation levels exhibited stark variation in levels of sensitivity and adaptive capacity to climate and nonclimate related shocks. Our findings indicate that this variation is partly driven by cultural, historical, and environmental resource use specialisation strategies and partly by differences in local governance capacity and the level of social organisation. Emerging governmentled initiatives to promote climate change adaptation in the region would benefit from taking these factors into account when designing local implementation strategies and priorities.

    Full Text Available Managing workplace diversity has become a priority concern among organizations in the United Arab Emirates (UAE today. The UAE has one of the world's largest net migration rates, and the number of workers from India, the Philippines, Indonesia, Australia, the USA, among other countries, has increased significantly in recent decades. The UAE's cross-border mobility has resulted in the interaction of people with diverse language, customs and ethnic backgrounds. Although diversity has been shown to have a number of benefits, including enhanced employee creativity and competence, this recognition is often found more in theory than actual practice. Diversity can also lead to miscommunication, dysfunctional adaptation behaviors and the creation of barriers that reduce the benefits diversity can bring to the organization. Due to the nature of the UAE workplace, which is dominated by a foreign workforce, this study critically analyzes the benefits and challenges organizations face in the diverse workplaces of the United Arab Emirates. The study used a multi-method approach combining survey data from 450 surveys of foreign workers with qualitative data from interviews with native officials of organizations. It is an attempt to compare the views of UAE workplace experience from two different groups—non-native workers and native officials. The research found a generally favorable view toward workplace diversity from the perspective of surveyed employees. However, when asked more detailed questions about company policy, a significant segment of respondents expressed reservations about their employer’s ability to implement successful intercultural communication and diversity practices.

    Decision support systems are known to be helpful for professionals in many medical professions. In social work, decision support systems have had modest use, accompanied by strong criticism from the profession but often by praise from political management. In this study the aim of the authors was to collect and report on the published evidence on decision support systems in social work. The conclusion of the authors is that a decision support system gives support to social workers in conducting a thorough investigation, but at the same time gives them the freedom to make autonomous decisions that might be the most helpful for and used by social workers. Their results also indicate that decision support systems focusing on atypical rather than typical cases are perceived as the most useful among experienced staff.

    Buildings consume over 40% of the total energy consumption in the U.S. A significant portion of the energy consumed in buildings is wasted because of the lack of controls or the inability to use existing building automation systems (BASs) properly. Much of the waste occurs because of our inability to manage and controls buildings efficiently. Over 90% of the buildings are either small-size (<5,000 sf) or medium-size (between 5,000 sf and 50,000 sf); these buildings currently do not use BASs to monitor and control their building systems from a central location. According to Commercial Building Energy Consumption Survey (CBECS), about 10% of the buildings in the U.S. use BASs or central controls to manage their building system operations. Buildings that use BASs are typically large (>100,000 sf). Lawrence Berkeley National Laboratory (LBNL), Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) were asked by the U.S. Department of Energy’s (DOE’s) Building Technologies Program (BTP) to identify monitoring and control needs for small- and medium-sized commercial buildings and recommend possible solutions. This study documents the needs and solutions for small- and medium-sized buildings.

    2005-04-06

    Suzuki-Miyaura coupling reactions of aryl and heteroaryl halides with aryl-, heteroaryl- and vinylboronic acids proceed in very good to excellent yield with the use of 2-(2',6'-dimethoxybiphenyl)dicyclohexylphosphine, SPhos (1). This ligand confers unprecedented activity for these processes, allowing reactions to be performed at low catalyst levels, to prepare extremely hindered biaryls and to be carried out, in general, for reactions of aryl chlorides at room temperature. Additionally, structural studies of various 1.Pd complexes are presented along with computational data that help elucidate the efficacy that 1 imparts on Suzuki-Miyaura coupling processes. Moreover, a comparison of the reactions with 1 and with 2-(2',4',6'-triisopropylbiphenyl)diphenylphosphine (2) is presented that is informative in determining the relative importance of ligand bulk and electron-donating ability in the high activity of catalysts derived from ligands of this type. Further, when the aryl bromide becomes too hindered, an interesting C-H bond functionalization-cross-coupling sequence intervenes to provide product in high yield.

    The continued development and commercialization of high temperature superconductors (HTS) may enable the construction of compact, net-energy tokamaks. HTS, in contrast to present generation low temperature superconductors, offers improved performance in high magnetic fields, higher current density, stronger materials, higher temperature operation, and simplified assembly. Using HTS along with community-consensus confinement physics (H98 =1) may make it possible to achieve net-energy (Q>1) or burning plasma conditions (Q>5) in DIII-D or ASDEX-U sized, conventional aspect ratio tokamaks. It is shown that, by operating at high plasma current and density enabled by the high magnetic field (B>10T), the required triple products may be achieved at plasma volumes under 20m3, major radii under 2m, with external heating powers under 40MW. This is at the scale of existing devices operated by laboratories, universities and companies. The trade-offs in the core heating, divertor heat exhaust, sustainment, stability, and proximity to known plasma physics limits are discussed in the context of the present tokamak experience base and the requirements for future devices. The resulting HTS-based design space is compared and contrasted to previous studies on high-field copper experiments with similar missions. The physics exploration conducted with such HTS devices could decrease the real and perceived risks of ITER exploitation, and aid in quickly developing commercially-applicable tokamak pilot plants and reactors.

  17. National Energy Efficiency Evaluation, Measurement and Verification (EM&V) Standard: Scoping Study of Issues and Implementation Requirements

    Schiller Consulting, Inc.; Schiller, Steven R.; Goldman, Charles A.; Galawish, Elsia

    2011-02-04

    This report is a scoping study that identifies issues associated with developing a national evaluation, measurement and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities. The objectives of this study are to identify the scope of such a standard and define EM&V requirements and issues that will need to be addressed in a standard. To explore these issues, we provide and discuss: (1) a set of definitions applicable to an EM&V standard; (2) a literature review of existing guidelines, standards, and 'initiatives' relating to EM&V standards as well as a review of 'bottom-up' versus 'top-down' evaluation approaches; (3) a summary of EM&V related provisions of two recent federal legislative proposals (Congressman Waxman's and Markey's American Clean Energy and Security Act of 2009 and Senator Bingaman's American Clean Energy Leadership Act of 2009) that include national efficiency resource requirements; (4) an annotated list of issues that that are likely to be central to, and need to be considered when, developing a national EM&V standard; and (5) a discussion of the implications of such issues. There are three primary reasons for developing a national efficiency EM&V standard. First, some policy makers, regulators and practitioners believe that a national standard would streamline EM&V implementation, reduce costs and complexity, and improve comparability of results across jurisdictions; although there are benefits associated with each jurisdiction setting its own EM&V requirements based on their specific portfolio and evaluation budgets and objectives. Secondly, if energy efficiency is determined by the US Environmental Protection Agency to be a Best Available Control Technology (BACT) for avoiding criteria pollutant and/or greenhouse gas emissions, then a standard can be required for documenting the emission reductions resulting from efficiency actions. The third reason for a national

    This study shows that, while there is a certain degree of institutional and project development capacity in the region and significant Clean Development Mechanism (CDM) potential, very little of this potential is currently being tapped. National institutional structures are mostly very new, understaffed, and working in isolation from each other. There are ongoing national CDM capacity building programmes in several SADC countries that will address barriers and develop projects at a national level, but there are also regional opportunities that these programmes will not address. For some of large scale project opportunities such as landfill gas, industrial energy use, fugitive emission and transport, a national approach is required because these projects depend on local industrial base, regulatory environment, and are also large enough that the carbon revenue can cover the transaction costs. There are a few key areas that should be addressed, however, at a regional level: Energy trade and power development: any low carbon power projects that are developed to serve regional energy needs and displace coal fired power can only receive carbon credits if the baseline is a regional power grid rather than just a national grid. This is also true for large scale energy efficiency projects in countries that have only hydropower - these would not receive any carbon credits unless there is justification for a regional grid definition that includes fossil fuel fired power stations.Small scale projects: While the total potential for small scale renewables may not be large in terms of tonnes of CO{sub 2} mitigated, the local development impacts of distributed renewable energy and energy efficiency projects are very large. For these projects to be implemented at a large enough scale to recoup the transaction costs of project development, a regional approach is critical. The CDM 'Programme of Activities' (PoA) approach is ideally suited for such regional small scale energy

  19. Improving the accessibility and re-use of environmental models through provision of model metadata - a scoping study

    There has been an increasing interest both from academic and commercial organisations over recent years in developing hydrologic and other environmental models in response to some of the major challenges facing the environment, for example environmental change and its effects and ensuring water resource security. This has resulted in a significant investment in modelling by many organisations both in terms of financial resources and intellectual capital. To capitalise on the effort on producing models, then it is necessary for the models to be both discoverable and appropriately described. If this is not undertaken then the effort in producing the models will be wasted. However, whilst there are some recognised metadata standards relating to datasets these may not completely address the needs of modellers regarding input data for example. Also there appears to be a lack of metadata schemes configured to encourage the discovery and re-use of the models themselves. The lack of an established standard for model metadata is considered to be a factor inhibiting the more widespread use of environmental models particularly the use of linked model compositions which fuse together hydrologic models with models from other environmental disciplines. This poster presents the results of a Natural Environment Research Council (NERC) funded scoping study to understand the requirements of modellers and other end users for metadata about data and models. A user consultation exercise using an on-line questionnaire has been undertaken to capture the views of a wide spectrum of stakeholders on how they are currently managing metadata for modelling. This has provided a strong confirmation of our original supposition that there is a lack of systems and facilities to capture metadata about models. A number of specific gaps in current provision for data and model metadata were also identified, including a need for a standard means to record detailed information about the modelling

    Full Text Available Abstract Background Across the developing world health care services are most often delivered in the private sector and social franchising has emerged, over the past decade, as an increasingly popular method of private sector health care delivery. Social franchising aims to strengthen business practices through economies of scale: branding clinics and purchasing drugs in bulk at wholesale prices. While quality is one of the established goals of social franchising, there is no published documentation of how quality levels might be set in the context of franchised private providers, nor what quality assurance measures can or should exist within social franchises. The aim of this study was to better understand the quality assurance systems currently utilized in social franchises, and to determine if there are shared standards for practice or quality outcomes that exist across programs. Methods The study included three data sources and levels of investigation: 1 Self-reported program data; 2 Scoping telephone interviews; and 3 In-depth field interviews and clinic visits. Results Social Franchises conceive of quality assurance not as an independent activity, but rather as a goal that is incorporated into all areas of franchise operations, including recruitment, training, monitoring of provider performance, monitoring of client experience and the provision of feedback. Conclusions These findings are the first evidence to support the 2002 conceptual model of social franchising which proposed that the assurance of quality was one of the three core goals of all social franchises. However, while quality is important to franchise programs, quality assurance systems overall are not reflective of the evidence to-date on quality measurement or quality improvement best practices. Future research in this area is needed to better understand the details of quality assurance systems as applied in social franchise programs, the process by which quality assurance

    Since mobility and social participation are key determinants of health and quality of life, it is important to identify factors associated with them. Although several investigations have been conducted on the neighborhood environment, mobility and social participation, there is no clear integration of the results. This study aimed to provide a comprehensive understanding regarding how the neighborhood environment is associated with mobility and social participation in older adults. A rigorous methodological scoping study framework was used to search nine databases from different fields with fifty-one keywords. Data were exhaustively analyzed, organized and synthesized according to the International Classification of Functioning, Disability and Health (ICF) by two research assistants following PRISMA guidelines, and results were validated with knowledge users. The majority of the 50 selected articles report results of cross-sectional studies (29; 58%), mainly conducted in the US (24; 48%) or Canada (15; 30%). Studies mostly focused on neighborhood environment associations with mobility (39; 78%), social participation (19; 38%), and occasionally both (11; 22%). Neighborhood attributes considered were mainly 'Pro ducts and technology' (43; 86) and 'Services, systems and policies' (37; 74%), but also 'Natural and human-made changes' (27; 54%) and 'Support and relationships' (21; 42%). Mobility and social participation were both positively associated with Proximity to resources and recreational facilities, Social support, Having a car or driver's license, Public transportation and Neighborhood security, and negatively associated with Poor user-friendliness of the walking environment and Neighborhood insecurity. Attributes of the neighborhood environment not covered by previous research on mobility and social participation mainly concerned 'Attitudes', and 'Services, systems and policies'. Results from this comprehensive synthesis of empirical studies on associations of

    Full Text Available Quality of product design, which is expected from manufacturers on world market these days, could be provided exclusively by integral approach to product design. Such approach aims to achievement of optimal design solution of product, which is in line with a number of requirements, conditions and limitations of functionality, technology, market and usage. Only those manufacturers who are able to provide such approach to product design have prospective on market. This paper deals with a case study of neglect of integral approach to product design and its consequencies, in order to spread awareness of necessity of its adoption. Scope of this case study is focused on bridge crane whose working vibrations are meant to be potential cause of occupational desease of spinal column of crane operator.

  9. Anger perceptually and conceptually narrows cognitive scope.

    Gable, Philip A; Poole, Bryan D; Harmon-Jones, Eddie

    2015-07-01

    For the last 50 years, research investigating the effect of emotions on scope of cognitive processing was based on models proposing that affective valence determined cognitive scope. More recently, our motivational intensity model suggests that this past work had confounded valence with motivational intensity. Research derived from this model supports the idea that motivational intensity, rather than affective valence, explains much of the variance emotions have on cognitive scope. However, the motivational intensity model is limited in that the empirical work has examined only positive affects high in approach and negative affects high in avoidance motivation. Thus, perhaps only approach-positive and avoidance-negative states narrow cognitive scope. The present research was designed to clarify these conceptual issues by examining the effect of anger, a negatively valenced approach-motivated state, on cognitive scope. Results revealed that anger narrowed attentional scope relative to a neutral state and that attentional narrowing to anger was similar to the attentional narrowing caused by high approach-motivated positive affects (Study 1). This narrowing of attention was related to trait approach motivation (Studies 2 and Study 3). Anger also narrowed conceptual cognitive categorization (Study 4). Narrowing of categorization related to participants' approach motivation toward anger stimuli. Together, these results suggest that anger, an approach-motivated negative affect, narrows perceptual and conceptual cognitive scope. More broadly, these results support the conceptual model that motivational intensity per se, rather than approach-positive and avoidance-negative states, causes a narrowing of cognitive scope.

    One of the major goals of NASA’s Earth Observing System (EOS) program was to study the Earth-Atmosphere System in an integrated fashion. As part of this vision, a series of individual and multi-sensor satellites were launched. With the launch of multiple sensors on several satellites, there is an increasing need to not only analyze data from individual sensors but from a combination of sensors on the same satellite or multiple satellites. Being able to juxtapose and combine these data sets should increase our ability to more effectively analyze various research scenarios. Currently, there are limited tools available for classifying images into one of several classes (e.g. clouds, aerosol, vegetation, desert, etc) on a pixel-by-pixel basis especially in complex cases when aerosols are mixed with clouds or when aerosols are over inhomogeneous surfaces. For example, the MODIS algorithms for detecting aerosols over land and ocean use a set of simple spatial and spectral thresholds that may not be adequate for complex cases over deserts when the surface is bright with clouds and aerosols in different layers and misclassification is possible. Over the Saharan desert mineral dust could be mixed with biomass burning aerosols, could occur in different layers, or thin cirrus cloud could pose additional ‘contamination’ problems. This poster will present GLIDER, a free software tool currently being developed to address these science needs. GLIDER provides users with a easy to use tool to visualize, analyze and mine satellite imagery. The poster will describe the tool’s unique features that will make it invaluable scientists for conducting air quality studies based on satellite imagery.

  13. High Quality Data for Grid Integration Studies

    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. The existing electric grid infrastructure in the US in particular poses significant limitations on wind power expansion. In this presentation we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets are presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. The need for high-resolution weather data pushes modeling towards finer scales and closer synchronization. We also present how we anticipate such datasets developing in the future, their benefits, and the challenges with using and disseminating such large amounts of data.

    The IEA has identified energy efficiency as essential to achieving a sustainable energy future. In order to improve energy efficiency in industry one of the priority areas for further action is the promotion of more and higher quality energy management (EM) activity. However, there are significant gaps in the current implementation of EM. One method of bridging these gaps would be the creation of an EM Action NetworK (EMAK) to bring practical support to energy managers, connect energy managers to energy policy makers, and interconnect these networks globally. The paper describes possible aims, activities, scope, structure, timelines and approaches related to EMAK and looks at specific tasks that would be important in the set-up and implementation.

    improvement in a broad range of outcomes and provide an insight into the criteria for the success of social prescribing services. Conclusions Our study revealed the varied models of social prescribing and nonmedical, community-based services available to people with type 2 diabetes and the extent of evaluation of these, which would not have been achieved by searching databases alone. The findings of this scoping study do not prove that social prescribing is an effective measure for people with type 2 diabetes in the United Kingdom, but can be used to inform future evaluation and contribute to the development of the evidence base for social prescribing. Accessing Web-based information provides a potential method for investigating how specific innovative health concepts, such as social prescribing, have been translated, implemented, and evaluated in practice. Several challenges were encountered including defining the concept, focusing on process plus intervention, and searching diverse, evolving Web-based sources. Further exploration of this approach will inform future research on the application of innovative health care concepts into practice. PMID:28153817

    2009-04-01

    To find out an approach to water quality management through correlation studies between various water quality parameters, the statistical regression analysis for six data points of underground drinking water of different hand pumps at J. P. Nagar was carried out. The comparison of estimated values with W.H.O drinking water standards revealed that water of the study area is polluted with reference to a number of physico-chemical parameters studied. Regression analysis suggests that conductivity of underground water is found to be significantly correlated with eight out of twelve water quality parameters studied. It may be suggested that the underground drinking water quality at J. P. Nagar can be checked very effectively by controlling the conductivity of water. The present study may be treated one step forward towards the water quality management.

    Parry, Yvonne Karen; Grant, Julian; Burke, Lynette

    2016-09-01

    Homeless families are the fastest growing segment of the homelessness population. Homelessness services are often the first to know when children are at risk of disengagement with health, welfare and education services. Changes to Australian policy to explicitly attend to the needs of children are attempts to address the complexity of, and provide better outcomes for, homeless children. There are mounting levels of evidence describing some of the needs of children who are homeless. Using the scoping study methodological framework, this review of academic and grey literature identified the extent to which service providers provide for the needs of homeless children. The literature search was conducted from September 2012 to April 2013 using ProQuest, Science Direct, Sage and OVID databases. Therefore, the objectives of this scoping study were to: (i) identify the specific needs of children in homelessness; (ii) describe recent changes in policy relating to care for children in homelessness services; (iii) explore the evidence on how service providers can enact care for children in homelessness services; (iv) identify the types of practice changes that are needed to optimise outcomes for children; and (v) identify the gaps in service delivery. This article describes the Australian policy changes and explores the potential impact of subsequent sector reforms on the internal practices in front-line homelessness services, in order to overcome structural and systemic barriers, and promote opportunities for children in homeless families. This scoping study literature review contributes to the understanding of the impact of policy change on front-line staff and suggests possible practice changes and future research options. © 2015 John Wiley & Sons Ltd.

    GreenLightTM procedure is an effective and economical way of treatment of benign prostate hyperplasia (BPH); there are almost a million of patients treated with GreenLightTM worldwide. During the surgical procedure, the surgeon or physician will rely on the monitoring video system to survey and confirm the surgical progress. There are a few obstructions that could greatly affect the image quality of the monitoring video, like laser glare by the tissue and body fluid, air bubbles and debris generated by tissue evaporation, and bleeding, just to name a few. In order to improve the physician's visual experience of a laser surgical procedure, the system performance parameter related to image quality needs to be well defined. However, since image quality is the integrated set of perceptions of the overall degree of excellence of an image, or in other words, image quality is the perceptually weighted combination of significant attributes (contrast, graininess …) of an image when considered in its marketplace or application, there is no standard definition on overall image or video quality especially for the no-reference case (without a standard chart as reference). In this study, Subjective Quality Factor (SQF) and acutance are used for no-reference image quality evaluation. Basic image quality parameters, like sharpness, color accuracy, size of obstruction and transmission of obstruction, are used as subparameter to define the rating scale for image quality evaluation or comparison. Sample image groups were evaluated by human observers according to the rating scale. Surveys of physician groups were also conducted with lab generated sample videos. The study shows that human subjective perception is a trustworthy way of image quality evaluation. More systematic investigation on the relationship between video quality and image quality of each frame will be conducted as a future study.

    There is fragmented information about the different needs following a spinal cord injury (SCI). Expressed SCI needs can be met or unmet, they change along the rehabilitation continuum (eg, acute, rehabilitation and reintegration into the community) and can be different for traumatic and non traumatic SCI. The general objective of this scoping study is to evaluate and integrate the needs of individuals with traumatic and non-traumatic SCI, their family caregivers and those reported by rehabilitation professionals from the time of rehabilitation admission to community reintegration. The specific objectives are to: (A) synthesise the needs of individuals with SCI as perceived by themselves, their family caregivers and rehabilitation professionals using two theoretical models, (B) classify needs as met and unmet, (C) explore the evolution of met/unmet needs from the time of rehabilitation admission to community reintegration and (D) provide recommendations to improve SCI care. METHODS AND ANALYSIS: (A) identifying the most frequent met and unmet needs reported by adults with traumatic and non-traumatic SCI, their family caregivers and their rehabilitation professionals from the time of rehabilitation admission to community reintegration; (B) identifying relevant studies with a search in electronic databases; (C) charting the data based on categories refined and adjusted with a stakeholder group; (D) collating, summarising and reporting the results using two analytical frameworks (Maslow's hierarchical model of human needs and the Ferrans et al's model of health-related quality of life) and (E) a stakeholder consultation phase. The results of this scoping study will allow understanding SCI needs from the time of rehabilitation admission to community reintegration from the perspective of different stakeholders.

    Shaikh, Shafaque

    2016-01-01

    Background Diverticular disease is a widely prevalent disease in western society, and acute diverticulitis is a common acute surgical presentation. However, there is a lack of level 1 evidence addressing the multifaceted presentations associated with acute diverticulitis. There is also a lack of robust epidemiological data that could be used to meaningfully inform randomised controlled trials. The National CADS project aims to generate baseline data for a cohort of patients managed for clinically suspected acute diverticulitis and evaluate the impact of variability in the management approach on patient outcomes in the short (3 months) and long (2 years) term. Method A Unit policy questionnaire will be completed by the principal investigator from all participating centres prior to study initiation. All patients aged above 18 years admitted with clinical suspicion of acute diverticulitis will be included from UK hospitals providing acute surgical care. Demographic, clinical, inpatient stay and outpatient follow-up data will be collected for index admissions between July and September 2014, 3 months follow-up and finally a 2-year follow-up. Results The study attracted participation from 108 centres nationally and has so far generated data on 2500 patients admitted between 1 July 2014 and 30 September 2014. Short-term follow-up data have been obtained for this cohort. Conclusions The National CADS study is currently ongoing with the long-term outcomes data anticipated to be submitted in autumn of 2016.

    Margaret M Demment

    Full Text Available Breast and cervical cancers have emerged as major global health challenges and disproportionately lead to excess morbidity and mortality in low- and middle-income countries (LMICs when compared to high-income countries. The objective of this paper was to highlight key findings, recommendations, and gaps in research and practice identified through a scoping study of recent reviews in breast and cervical cancer in LMICs.We conducted a scoping study based on the six-stage framework of Arskey and O'Malley. We searched PubMed, Cochrane Reviews, and CINAHL with the following inclusion criteria: 1 published between 2005-February 2015, 2 focused on breast or cervical cancer 3 focused on LMIC, 4 review article, and 5 published in English.Through our systematic search, 63 out of the 94 identified cervical cancer reviews met our selection criteria and 36 of the 54 in breast cancer. Cervical cancer reviews were more likely to focus upon prevention and screening, while breast cancer reviews were more likely to focus upon treatment and survivorship. Few of the breast cancer reviews referenced research and data from LMICs themselves; cervical cancer reviews were more likely to do so. Most reviews did not include elements of the PRISMA checklist.Overall, a limited evidence base supports breast and cervical cancer control in LMICs. Further breast and cervical cancer prevention and control studies are necessary in LMICs.

    Quality of life (QOL) can be affected by the presence of mental disorders, like Obsessive-Compulsive Disorder (OCD). Thus, the evaluation and monitoring of QOL in patients with mental disorders enables the identification of priorities, making it possible to implement actions to improve QOL among health system users. The scope of this article is to measure QOL in OCD patients in primary health care. It involves a cross-sectional study with a convenience sample including all users of three Basic Health Units of Pelotas in the State of Rio Grande do Sul, Brazil. The quality of life was measured with the WHOQOL-Bref and the OCD was assessed using the Mini-International Neuropsychiatric Interview (M.I.N.I.) This study included 1081 individuals. The prevalence of OCD was 3.9%. OCD patients had a lower average in all domains of QOL when compared to individuals without OCD (p < 0.001). The findings of this study emphasize the importance of using QOL as a monitoring tool of the disorder in basic health care.

    2012-05-16

    Synthetic and mechanistic aspects of the diarylborinic acid-catalyzed regioselective monofunctionalization of 1,2- and 1,3-diols are presented. Diarylborinic acid catalysis is shown to be an efficient and general method for monotosylation of pyranoside derivatives bearing three secondary hydroxyl groups (7 examples, 88% average yield). In addition, the scope of the selective acylation, sulfonylation, and alkylation is extended to 1,2- and 1,3-diols not derived from carbohydrates (28 examples); the efficiency, generality, and operational simplicity of this method are competitive with those of state-of-the-art protocols including the broadly applied organotin-catalyzed or -mediated reactions. Mechanistic details of the organoboron-catalyzed processes are explored using competition experiments, kinetics, and catalyst structure-activity relationships. These experiments are consistent with a mechanism in which a tetracoordinate borinate complex reacts with the electrophilic species in the turnover-limiting step of the catalytic cycle.

    A fast and efficient protocol for the palladium(II)-catalyzed production of aryl ketones from sodium arylsulfinates and various organic nitriles under controlled microwave irradiation has been developed. The wide scope of the reaction has been demonstrated by combining 14 sodium arylsulfinates and 21 nitriles to give 55 examples of aryl ketones. One additional example illustrated that, through the choice of the nitrile reactant, benzofurans are also accessible. The reaction mechanism was investigated by electrospray ionization mass spectrometry and DFT calculations. The desulfitative synthesis of aryl ketones from nitriles was also compared to the corresponding transformation starting from benzoic acids. Comparison of the energy profiles indicates that the free energy requirement for decarboxylation of 2,6-dimethoxybenzoic acid and especially benzoic acid is higher than the corresponding desulfitative process for generating the key aryl palladium intermediate. The palladium(II) intermediates detected by ESI-MS and the DFT calculations provide a detailed understanding of the catalytic cycle.

Using an algebraic interpretive approach, the narratives collected during interviews are analyzed as Bayesian inferences and the developed theory is tested....... The findings recast the relationship between science and patents as a process in which the way the transformation of the scientific invention is handled has an effect on the breadth of the patent scope. Unleashing patent scope surplus is dependent on processes related to abstraction and cognitive variety......, which can be mobilized by patent experts with both an in-depth understanding of the scientific discovery, due to their educational background in the life sciences, and capabilities within the legal framework for patenting.

    Umair Shahid, Syed; Iqbal, Javed

    2016-10-01

    Water quality is considered as a major issue in mega cities of developing countries. The city of Lahore has over 10 million populations with the highest population density in the Punjab Province, Pakistan. Groundwater is the main source of drinking water in Lahore. The groundwater quality should be regularly monitored to cope up with drinking water quality issues. The water quality index (WQI), previously used in many studies was usually based on one-year data to analyze the water quality situation of the study area. However, the results obtained from the data, based on single observation from different points may have distortion. This might have occurred due to the inclusion of multiple types of errors induced in the data as a result of improper sampling design, lack of expertise in terms of both sampling method and sample testing, instrumental and human errors, etc. Therefore, the study evaluated the groundwater physicochemical parameters (turbidity, pH, total dissolved solids, hardness, chlorides, alkalinity and calcium) for three years. The averaged water quality index (AWQI) was computed using ArcGIS 10.3 model builder. The AWQI map indicated that the water quality in the study area was generally good except in few places like Anarkali, Baghbanpura, Allama Iqbal Town, Mughalpura and Mozang due to relatively higher turbidity levels. The results of this study can be used for decision making regarding provision of clean drinking water to the city of Lahore. Moreover, the methodology adopted in this study can be implemented in other mega cities as well to monitor groundwater quality.

    Social media has had a profound effect on how children and adolescents interact. While there are many benefits to the use of social media, cyberbullying has emerged as a potential harm, raising questions regarding its influence on mental health. To review existing publications that examine the health-related effects of cyberbullying via social media among children and adolescents. We searched 11 electronic databases from January 1, 2000, through January 17, 2012 (updated June 24, 2014). Studies were screened by 2 independent reviewers and were included if they reported primary research, described or evaluated the use of a social media tool in the context of cyberbullying, and were conducted with children or adolescents. Data were extracted by 1 reviewer and verified by a second. All studies were assessed by 2 reviewers for methodological quality using the Mixed Methods Appraisal Tool. Results were not pooled owing to heterogeneity in study objectives and outcomes; a narrative analysis is presented. Thirty-six studies in 34 publications were included. Most were conducted in the United States (21 [58.3%]), sampled middle and high school populations (24 [66.7%]), and included adolescents who were 12 to 18 years of age (35 [97.2%]). The median reported prevalence of cyberbullying was 23.0% (interquartile range, 11.0%-42.6%). Five studies reported inconsistent and/or weak correlations between cyberbullying and anxiety. Ten studies found a statistically significant association between cyberbullying and report of depression. Five studies investigated self-harm or suicidality, with conflicting results. Results indicate that the most common reason for cyberbullying is relationship issues, with girls most often being the recipients. Responses to cyberbullying are most often passive, with a pervasive lack of awareness or confidence that anything can be done. There is a consistent relationship across studies between cyberbullying and depression among children and adolescents

    2015-10-01

    Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a single measure for evaluating the multiple-item service quality construct based on the SERVQUAL model. A slack-based measure (SBM) of efficiency with constant inputs is used to calculate the PSQI. In addition, a non-linear programming model based on the SBM is proposed to delineate an improvement guideline and improve service quality. An empirical study is conducted to assess the applicability of the method proposed in this study. A large number of studies have used DEA as a benchmarking tool to measure service quality. These models do not propose a coherent performance evaluation construct and consequently fail to deliver improvement guidelines for improving service quality. The DEA models proposed in this study are designed to evaluate and improve service quality within a comprehensive framework and without any dependency on external data.

  14. Sustained metabolic scope.

    Peterson, C C; Nagy, K A; Diamond, J

    1990-03-01

    Sustained metabolic rates (SusMR) are time-averaged metabolic rates that are measured in free-ranging animals maintaining constant body mass over periods long enough that metabolism is fueled by food intake rather than by transient depletion of energy reserves. Many authors have suggested that SusMR of various wild animal species are only a few times resting (basal or standard) metabolic rates (RMR). We test this conclusion by analyzing all 37 species (humans, 31 other endothermic vertebrates, and 5 ectothermic vertebrates) for which SusMR and RMR had both been measured. For all species, the ratio of SusMR to RMR, which we term sustained metabolic scope, is less than 7; most values fall between 1.5 and 5. Some of these values, such as those for Tour de France cyclists and breeding birds, are surely close to sustainable metabolic ceilings for the species studied. That is, metabolic rates higher than 7 times RMR apparently cannot be sustained indefinitely. These observations pose several questions: whether the proximate physiological causes of metabolic ceilings reside in the digestive tract's ability to process food or in each tissue's metabolic capacity; whether ceiling values are independent of the mode of energy expenditure; whether ceilings are set by single limiting physiological capacities or by coadjusted clusters of capacities (symmorphosis); what the ultimate evolutionary causes of metabolic ceilings are; and how metabolic ceilings may limit animals' reproductive effort, foraging behavior, and geographic distribution.

    Full Text Available The success of every housing area is determined by its user satisfaction level, living there. The quality of the house, its spaces within the unit, housing neighbourhood and green open space can directly influence the quality of life. Limitation of space following high land cost in an urban area, evaluation of the housing environment as a whole including the green open space needs to be studied as it affects the residents’ satisfaction level. This study concentrates on spaces within a housing area to evaluate the residents’ level of satisfaction of the Taman Melati Mastika (TMM, Kuala Lumpur and to understand how they perceived their quality of life through the housing environment and the availability of green open space. Thus, this research was carried out through site observation and analysis, and self-administered questionnaire survey. 247 questionnaire surveys were distributed to the residents of TMM and (n=62 responded. When focused on the housing unit, this study provides insight on the types of outdoor spaces (front yard-front lane and backyard-back lane and their elements and utilization, and quality of housing spaces toward users’ quality of life in TMM, Kuala Lumpur. On the green open space, the assessment of the quality of life is based on three factors that are the safety level of the neighbourhood and park, health issues related to housing environment and park as well as the satisfaction on the housing amenities and park facilities. The result of this study suggests that the residents are satisfied with the existing spaces within their compound and adjacent to it and this lead towards the overall satisfaction living in the area. The quality of space and good utilisation of housing areas can lead towards a better quality of life in the Terrace housing area is confirmed.

    Full Text Available Poor sleep quality impairs cognition, including executive functions and concentration, but there has been little direct research on the relationships between sleep quality and mind wandering or daydreaming. Evening chronotype is associated with poor sleep quality, more mind wandering and more daydreaming; negative affect is also a mutual correlate. This exploratory study investigated how mind wandering and daydreaming are related to different aspects of sleep quality, and whether sleep quality influences the relationships between mind wandering/daydreaming and negative affect, and mind wandering/daydreaming and chronotype. Three surveys (Ns = 213; 190; 270 were completed with Chinese adults aged 18-50, including measures of sleep quality, daytime sleepiness, mind wandering, daydreaming, chronotype and affect (positive and negative. Higher frequencies of mind wandering and daydreaming were associated with poorer sleep quality, in particular with poor subjective sleep quality and increased sleep latency, night-time disturbance, daytime dysfunction and daytime sleepiness. Poor sleep quality was found to partially mediate the relationships between daydreaming and negative affect, and mind wandering and negative affect. Additionally, low positive affect and poor sleep quality, in conjunction, fully mediated the relationships between chronotype and mind wandering, and chronotype and daydreaming. The relationships between mind wandering/daydreaming and positive affect were also moderated by chronotype, being weaker in those with a morning preference. Finally, while daytime sleepiness was positively correlated with daydream frequency, it was negatively correlated with a measure of problem-solving daydreams, indicating that more refined distinctions between different forms of daydreaming or mind wandering are warranted. Overall, the evidence is suggestive of a bi-directional relationship between poor sleep quality and mind wandering/daydreaming, which

    Background/Aims The over-the-scope clip (OTSC) is a device used for endoscopic closure of perforations, leaks and fistulas, and for endoscopic hemostasis. To evaluate the clinical effectiveness and safety of OTSC. Methods Between October 2013 and November 2015, 12 patients underwent OTSC placement by an experienced endoscopist. OTSC was used for the closure of gastrointestinal (GI) leaks and fistula in six patients, three of which were iatrogenic (esophageal, gastric, and duodenal) and three of which were inflammatory. In six patients, OTSC was used for hemostasis of non-variceal upper GI bleeding. Endoscopic tattooing using India ink was used to assist the accurate placement of the clip. Results All subjects except one with a colonic defect experienced immediate technical success as well as long-term clinical success, during a mean follow-up of 6 weeks. Only one clip was required to close each of the GI defects and to achieve hemostasis in all patients. There were no misfirings or complications of clips. The procedure was well tolerated, and patients were hospitalized for an average of 8 days (range, 3 to 10). Antiplatelet therapy was continued in patients with GI bleeding. Conclusions In our experience, OTSC was safe and effective for the closure of GI defect and to achieve hemostasis of non-variceal GI bleeding. PMID:27802375

    As part of the retrospective evaluation of the U.S. Department of Energy s low-income Weatherization Assistance Program that was led by Oak Ridge National Laboratory (ORNL), an assessment of the impacts of weatherization on indoor air quality (IAQ) was conducted. This assessment included nearly 500 treatment and control homes across the country. Homes were monitored for carbon monoxide, radon, formaldehyde, temperature and humidity pre- and post-weatherization. This report focuses on the topic of radon and addresses issues not thoroughly discussed in the original IAQ report. The size, scope and rigor of the radon component of the IAQ study are compared to previous studies that assessed the impacts of weatherization on indoor radon levels. It is found that the ORNL study is by far the most extensive study conducted to date, though the ORNL results are consistent with the findings of the other studies. However, the study does have limitations related to its reliance on short-term measurements of radon and inability to attribute changes in radon levels in homes post-weatherization to specific weatherization measures individually or in combination.

  1. A study of high-quality foamed fracturing fluid properties

    Successful stimulation and extraction of hydrocarbons from unconventional reservoirs have created different approaches to the stimulation process. Types of treatment vary from slickwater stimulations, low dosages of polyacrylamide, conventional crosslinked, or linear gelled fluids. There has also been successful treatments in implementing a high-quality foam stimulation in some shale formations. The advantage of using a high quality foam is its reduced environmental impact as it uses very small amounts of water as compared to high-rate slickwater stimulations. However, there is little published information on high-quality fluid foam properties. In order to examine the rheological properties of high-quality foamed fracturing fluids and compare it to other fluids that are common in fracturing treatments, this paper presented a study that examined the fluid characteristics of high-quality foams as compared to typical 50-70 quality foams. The study demonstrated trends of viscosity, foam stability and temperature sensitivity of high-quality foams using xanthan, guar-based gelling agents and viscoelastic base fluids. The paper described the test equipment and procedures, as well as the test results. The tests using guar as the base fluid gellant demonstrated increasing viscosity with increased foam quality. 2 tabs., 22 figs.

    Automatic methods to evaluate the perceptual quality of a digital video sequence have widespread applications wherever the end-user is a human. Several objective video quality assessment (VQA) algorithms exist, whose performance is typically evaluated using the results of a subjective study performed by the video quality experts group (VQEG) in 2000. There is a great need for a free, publicly available subjective study of video quality that embodies state-of-the-art in video processing technology and that is effective in challenging and benchmarking objective VQA algorithms. In this paper, we present a study and a resulting database, known as the LIVE Video Quality Database, where 150 distorted video sequences obtained from 10 different source video content were subjectively evaluated by 38 human observers. Our study includes videos that have been compressed by MPEG-2 and H.264, as well as videos obtained by simulated transmission of H.264 compressed streams through error prone IP and wireless networks. The subjective evaluation was performed using a single stimulus paradigm with hidden reference removal, where the observers were asked to provide their opinion of video quality on a continuous scale. We also present the performance of several freely available objective, full reference (FR) VQA algorithms on the LIVE Video Quality Database. The recent MOtion-based Video Integrity Evaluation (MOVIE) index emerges as the leading objective VQA algorithm in our study, while the performance of the Video Quality Metric (VQM) and the Multi-Scale Structural SIMilarity (MS-SSIM) index is noteworthy. The LIVE Video Quality Database is freely available for download1 and we hope that our study provides researchers with a valuable tool to benchmark and improve the performance of objective VQA algorithms.

    This letter report summarizes a scoping study that examined the potential importance of fresh fruit and vegetable pathways to dose. A simple production index was constructed with data collected from the Washington State Department of Agriculture (WSDA), the United States Bureau of the Census, and the United States Department of Agriculture (USDA). Hanford Environmental Dose Reconstruction (HEDR) Project staff from Battelle, Pacific Northwest Laboratories, in cooperation with members of the Technical Steering Panel (TSP), selected lettuce and spinach as the produce pathways most likely to impact dose. County agricultural reports published in 1956 provided historical descriptions of the predominant distribution patterns of fresh lettuce and spinach from production regions to local population centers. Pathway rankings and screening dose estimates were calculated for specific populations living in selected locations within the HEDR study area.

    To describe the ethical and methodological quality of non-interventional post-authorization studies promoted by Hospital Pharmacy Departments (HPD). HPD promoted studies in the 2009-2011 period included in the Spanish Agency of Medicines and Medical Devices (AEMPS) registry and/or published in "Farmacia Hospitalaria" were identified. The most relevant ethical and methodological characteristics were analyzed. Studies promoted by HPD were also compared with studies not promoted by HPD. Twenty two studies promoted by HPD, and registered in the AEMPS were identified. Within the registered studies HPD promoted studies had lower sample size estimation (41,5% vs 80%) and international scope (0% vs 24%) compared to non HPD promoted studies with significant differences (p Farmacia Hospitalaria have been registered in the AEMPS and had lower methodological quality than the registered studies promoted by HPD in characteristics such as presence of control group (3,8% vs 27,3%) (p = 0,0072) and the sample size estimation of (19,2% vs 42,8%) (p < 0,05). The management and the methodological and ethical characteristics of the studies promoted by HPD should be improved according to the regulation. The registration in the AEMPS might have a positive impact on the quality of these research protocols. Copyright © 2013 SEFH. Published by AULA MEDICA. All rights reserved.

    Full Text Available The scenario of quality is expanding exponentially. In the present-day world, quality is now in the driver's seat. With this globalisation of industrial products, many problems and opportunities have risen, primarily due to inconsistent standards existing in the market. The International Standards Organisation has tried (and seem to be very successful in doing so to standardise a minimum level of quality norms. These norms act as the foundation to implements total quality management (TQM. TQM has been identified as a philosophy of interdependent characteristics, such as customer focus, commitment, measurement, systematic support, and continuous improvement. This paper presents a case study on the implementation of ISO 9002: 1994 at Kerala Hitech Industries (KELTEC, with the benefits, hurdles faced, and shortcomings. Upgradation of KELTEC's quality management system to the requirements of ISO 9001: 2000 is currently under progress.

    We have been distilling the KamLAND liquid scintillator (LS) for the low energy solar neutrino observation. The distillation removes radioactive impurities from LS efficiently. We developed two types of high sensitivity radon detectors to monitor 222Rn contamination which causes a primary background source 210Pb. Their required sensitivity is several mBq/m3. The features and the measurement results of these detectors are presented. We also report the study of liquid scintillator properties after the distillation: attenuation length, light output and PPO density.

  12. A SCOPING STUDY: Development of Probabilistic Risk Assessment Models for Reactivity Insertion Accidents During Shutdown In U.S. Commercial Light Water Reactors

    2011-06-01

    This report documents the scoping study of developing generic simplified fuel damage risk models for quantitative analysis from inadvertent reactivity insertion events during shutdown (SD) in light water pressurized and boiling water reactors. In the past, nuclear fuel reactivity accidents have been analyzed both mainly deterministically and probabilistically for at-power and SD operations of nuclear power plants (NPPs). Since then, many NPPs had power up-rates and longer refueling intervals, which resulted in fuel configurations that may potentially respond differently (in an undesirable way) to reactivity accidents. Also, as shown in a recent event, several inadvertent operator actions caused potential nuclear fuel reactivity insertion accident during SD operations. The set inadvertent operator actions are likely to be plant- and operation-state specific and could lead to accident sequences. This study is an outcome of the concern which arose after the inadvertent withdrawal of control rods at Dresden Unit 3 in 2008 due to operator actions in the plant inadvertently three control rods were withdrawn from the reactor without knowledge of the main control room operator. The purpose of this Standardized Plant Analysis Risk (SPAR) Model development project is to develop simplified SPAR Models that can be used by staff analysts to perform risk analyses of operating events and/or conditions occurring during SD operation. These types of accident scenarios are dominated by the operator actions, (e.g., misalignment of valves, failure to follow procedures and errors of commissions). Human error probabilities specific to this model were assessed using the methodology developed for SPAR model human error evaluations. The event trees, fault trees, basic event data and data sources for the model are provided in the report. The end state is defined as the reactor becomes critical. The scoping study includes a brief literature search/review of historical events, developments of

    The ongoing Social Cognition Psychometric Evaluation (SCOPE) study is in the process of forming a gold-standard battery of social cognition tests for use in clinical trials. Previous SCOPE phases have not acknowledged key differences between social cognition skills and biases, and psychometric validity analyses might provide important information if tailored to bias-related outcomes. This study aims to validate these measures with such bias-related outcomes. Two measures of social cognitive bias - the Ambiguous Intention Hostility Questionnaire (AIHQ; hostile attribution bias) and Trustworthiness Task (distrust bias) - were reviewed according to their relationships to (1) current and prospective symptom levels, (2) questionnaires of trait paranoia and hostility and informant-rated hostility, (3) interpersonal conflict, as well as (4) relationships to measures of trait paranoia, hostility, and interpersonal conflict above and beyond the influence of clinically rated symptoms. Results supported hypotheses that social cognitive bias provides information about cognition, symptoms, and functioning related to interpersonal conflict. Each bias demonstrated relationships to trait paranoia questionnaires, hostility, or interpersonal conflict outcomes, and these persisted above and beyond the influence of clinically rated symptoms. Hostile attribution bias also predicted change in symptom levels over a brief interval. Overall, the current bias-specific psychometric analysis provides support for continued study of social cognitive biases. Hostile attribution bias may play a role in important outcome variables given relationships to emotional discomfort and suspiciousness symptoms, trait paranoia and hostility, interpersonal conflict, as well as prospective hostility symptoms. Distrust bias may also impact real-world functioning, as it is related to hostility, suspiciousness, and positive symptoms, trait paranoia, and hostility. Relationships of social cognitive biases to

    Connolly, Regina

    Despite the fact that service quality is a critical determinant of website success, studies show that consumers frequently view the service quality delivered through websites as unsatisfactory. This paper outlines a study that investigated the dimensions of website service excellence valued by Irish customers of a small-to-medium enterprise specialising in gifts. The E-S-QUAL measurement instrument was applied to the customers who purchase products online from this retailer, in order to determine their purchasing patterns and the dimensions of e-service quality that they value. The results of this study indicate the effectiveness of the instrument in determining gaps in e-service quality. The findings will be of benefit both to practitioners and researchers seeking to improve their understanding of the factors that contribute towards the creation and maintenance of consumer satisfaction in Irish online transactions.

    Full Text Available Trends in selection of a career in medicine vary from country to country. To plan future recruitment strategies and to balance distribution of physicians among medical specialties, each country needs to examine these reasons as part of educational research. The aim of this study was to explore the Anaesthesiology postgraduate students′ knowledge about anaesthesia as a speciality, their attitude towards anaesthesia as a career choice, stress levels during the period of postgraduation, views regarding Diploma in Anaesthesiology and undergraduate exposure to the subject. Eight hundred pretested questionnaires were provided to the anaesthesia postgraduate students attending various national level conferences in India. The collected data were statistically analysed using SPSS version 20. Only 31.6% of the students were aware of scope of anaesthesiology and 42.3% of students joined the speciality out of the interest to learn the subject, whereas 55.7% joined for other reasons, including non-availability of other specialties during medical postgraduate counselling. About 70% of students were stressed out during postgraduation, 31.6% found difficulty in accommodating the demands of challenging job and 3.8% went into depression. Majority of anaesthesiology postgraduate students were unaware of the scope of Anaesthesiology at the time of medical postgraduate counselling; only two-fifth of the students joined the speciality out of interest to learn the subject and most of them felt stressed out during the period of postgraduation. Majority of the students were of the opinion that Diploma in Anaesthesia was not a viable career option and should be scrapped.

    Full Text Available Quality of an academic study programme is evaluated by many: employees (internal evaluation and by external evaluators: experts, agencies and organisations. Internal and external evaluation of an academic programme follow written structure that resembles on one of the quality models. We believe the quality models (mostly derived from EFQM excellence model don’t fit very well into non-profit activities, policies and programmes, because they are much more complex than environment, from which quality models derive from (for example assembly line. Quality of an academic study programme is very complex and understood differently by various stakeholders, so we present dimensional evaluation in the article. Dimensional evaluation, as opposed to component and holistic evaluation, is a form of analytical evaluation in which the quality of value of the evaluand is determined by looking at its performance on multiple dimensions of merit or evaluation criteria. First stakeholders of a study programme and their views, expectations and interests are presented, followed by evaluation criteria. They are both joined into the evaluation model revealing which evaluation criteria can and should be evaluated by which stakeholder. Main research questions are posed and research method for each dimension listed.

    Full Text Available This study examines audit committee quality and its relationship with financial reporting quality. The population of this study consists of the companies listed in Bombay Stock Exchange (BSE between years 2002 and 2012. Using Godden sample size formula, 133 companies are selected randomly for the study. It is found that in most of the equity based listed companies at BSE under study have complied with the legal formalities, for instance, appointment of independent directors, number of meetings, size of the audit committee, legal qualifications and financial qualifications of the directors, as they were required for the listing at a stock exchange in India. Further, the analysis and tests state that board size, audit committee meetings and its size have relationship with the financial reporting practices, but the CEO tenure and hold, board independence, net income, proportion of independent directors on board, legal qualifications and financial qualifications of the directors and overlap of audit committee members on compensation committee, have no influence on the financial reporting practices. Thus, it may be inferred that the companies may improve the financial reporting quality, by managing the board size, audit committee meetings and size, as these characteristics have significant relationship with financial reporting quality.

    The authors conducted air quality measurements of the criteria pollutants carbon monoxide, nitrogen oxides, and ozone together with meteorological measurements at a park site southeast of College Station, TX, during the 2006 Texas Air Quality Study II (TexAQS). Ozone, a primary focus of the measurements, was above 80 ppb during 3 days and above 75 ppb during additional 8 days in summer 2006, suggestive of possible violations of the ozone National Ambient Air Quality Standard (NAAQS) in this area. In concordance with other air quality measurements during the TexAQS II, elevated ozone mixing ratios coincided with northerly flows during days after cold front passages. Ozone background during these days was as high as 80 ppb, whereas southerly air flows generally provided for an ozone background lower than 40 ppb. Back trajectory analysis shows that local ozone mixing ratios can also be strongly affected by the Houston urban pollution plume, leading to late afternoon ozone increases of as high as 50 ppb above background under favorable transport conditions. The trajectory analysis also shows that ozone background increases steadily the longer a southern air mass resides over Texas after entering from the Gulf of Mexico. In light of these and other TexAQS findings, it appears that ozone air quality is affected throughout east Texas by both long-range and regional ozone transport, and that improvements therefore will require at least a regionally oriented instead of the current locally oriented ozone precursor reduction policies.

    2015-03-01

    Disability discrimination legislation means that employees with a disability or mental illness are legally entitled to reasonable workplace accommodations that enable them to work effectively and safely. This scoping review aims to investigate the types of workplace accommodations provided for people with mental illness, and their costs and benefits. A literature search was conducted using five electronic databases. Peer reviewed research articles published between 1993 and June 2013 were included in this scoping review and their quality was assessed. Opinion papers, reports, and case descriptions were excluded. Nine studies explored workplace accommodations for people with mental illness. The most commonly reported work-related accommodations were flexible scheduling/reduced hours, modified training and supervision, and modified job duties/descriptions. The least common type of accommodation was physical modification to the workplace. For employees with persistent mental illness who were accessing a supported employment agency, the majority of accommodations related to support from the job coach or employment specialist, such as facilitating communication with the employer during hiring or on the job. The quality of the studies varied considerably and the benefits of the accommodations are not yet well documented. There is limited evidence that a larger number of workplace accommodations are associated with longer job tenure. Workplace accommodations appear to be important to support employees with mental illness, but more accessible information about how disability discrimination legislation applies to this population is needed. Future research should address the implementation and effectiveness of mental health-related workplace accommodations.

    2014-08-01

    Full Text Available Purpose: Computed tomography (CT, is an X-ray procedure that generates high quality cross-sectional images of the body, and by comparison to other radiological diagnosis, is responsible for higher doses to patients. This work studies the doses and image qualities produced from the default primary scanning factors of a Siemens CT machine and afterwards came up with scanning protocols that allow radiologists to obtain the necessary diagnostic information while reducing radiation doses to as low as reasonably achievable. Methods: Approximately 1000 CT scans from mostly common examinations; head, thorax, abdomen and pelvis routines were selected and analyzed for their image quality and radiation doses over a two year interval. Dose measurements were performed for the same routines using Computed Tomography Dose Index (CTDI phantoms, RTI barracuda system with electrometer, and CT dose Profiler detector to evaluate the doses delivered during these CT procedures. Subsequently, image quality checks were performed using the CT Catphan 600 and anthropomorphic phantoms. CTDI and Dose Length Product (DLP values were calculated for each scan. From analyzing these measurements, the appropriate machine scanning parameters were adjusted to reduce radiation does while at the same time providing good image quality.Results: Doses to patients using the default head sequence protocol had an average CTDIvol value of 65.45 mGy and a range of 7.10-16.80 mGy for thorax, abdomen and pelvis examinations whiles the new protocol had an average CTDIvol of 58.32 mGy for the head and a range of 3.83-15.24 mGy for the truck region. The DLP value for default head scans decreased from an average of 2279.85 mGy.cm to 874.53 mGy.cm with the new protocol. Tube potentials (KV and tube current-time (mAs had an effect on spatial resolution and low contrast detectability as well as doses. Conclusion: From the new protocols, lower values of KV and mAs together with other factors were

    2010-04-01

    The Nordic countries have a long tradition of providing comparable and high quality cancer data through the national population-based cancer registries and the capability to link the diverse large-scale biobanks currently in operation. The joining of these two infrastructural resources can provide a study base for large-scale studies of etiology, treatment and early detection of cancer. Research projects based on combined data from cancer registries and biobanks provides great opportunities, but also presents major challenges. Biorepositories have become an important resource in molecular epidemiology, and the increased interest in performing etiological, clinical and gene-environment-interaction studies, involving information from biological samples linked to population-based cancer registries, warrants a joint evaluation of the quality aspects of the two resources, as well as an assessment of whether the resources can be successfully combined into a high quality study. While the quality of biospecimen handling and analysis is commonly considered in different studies, the logistics of data handling including the linkage of the biobank with the cancer registry is an overlooked aspect of a biobank-based study. It is thus the aim of this paper to describe recommendations on data handling, in particular the linkage of biobank material to cancer registry data and the quality aspects thereof, based on the experience of Nordic collaborative projects combining data from cancer registries and biobanks. We propose a standard documentation with respect to the following topics: the quality control aspects of cancer registration, the identification of cases and controls, the identification and use of data confounders, the stability of serum components, historical storage conditions, aliquoting history, the number of freeze/thaw cycles and available volumes.

    Obesity affects one in three American adult women and is associated with overall mortality and major morbidities. A composite diet index to evaluate total diet quality may better assess the complex relationship between diet and obesity, providing insights for nutrition interventions. The purpose of the present investigation was to determine whether diet quality, defined according to the previously validated Framingham nutritional risk score (FNRS), was associated with the development of overweight or obesity in women. Over 16 years, we followed 590 normal-weight women (BMI Framingham Offspring and Spouse Study who presented without CVD, cancer or diabetes at baseline. The nineteen-nutrient FNRS derived from mean ranks of nutrient intakes from 3 d dietary records was used to assess nutritional risk. The outcome was development of overweight or obesity (BMI > or = 25 kg/m2) during follow-up. In a stepwise multiple logistic regression model adjusted for age, physical activity and smoking status, the FNRS was directly related to overweight or obesity (P for trend = 0.009). Women with lower diet quality (i.e. higher nutritional risk scores) were significantly more likely to become overweight or obese (OR 1.76; 95 % CI 1.16, 2.69) compared with those with higher diet quality. Diet quality, assessed using a comprehensive composite nutritional risk score, predicted development of overweight or obesity. This finding suggests that overall diet quality be considered a key component in planning and implementing programmes for obesity risk reduction and treatment recommendations.

    Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

    Using the Quality Oncology Practice Initiative, an affiliate program of ASCO, we outlined opioid-associated constipation (OAC) as a subject in need of quality improvement (QI) in our fellowship program at the University of Arkansas for Medical Sciences and Central Arkansas Veterans Healthcare System. We initiated a fellow-led QI project to advance the quality of patient care and provide a valuable avenue for QI training of young physicians. Fellows organized meetings with all stakeholders, addressed the scope of the problem, and devised strategies for OAC management. Monthly meetings were organized using Plan-Do-Study-Act principles. Mandatory check boxes were inserted into our electronic medical record templates to remind all physicians to identify patients on opioid medications and assess and address OAC. Final chart audit and patient satisfaction surveys were performed 6 months after project initiation. Assessment of OAC improved from 52% at baseline to 92% ( P Quality Oncology Practice Initiative helps identify areas in need of QI, and such fellow-led QI projects can serve as models for QI training of young physicians.

    The Border Air Quality Study (BAQS) is an ongoing study which supports the development of an international strategy for the Georgia Basin-Puget Sound airshed. The study investigates the association of health risks with the exposure to a range of air pollutants. It identified links between air pollutants and several health impacts ranging from asthma to birthweight. The tools developed for studying air quality provide greater spatial resolution, thus enabling the identification of pollution hot spots that require monitoring and intervention. The tools also provide spatially accurate exposure data for future research and enable land-use decisions that reduce risk to the most vulnerable populations, including children and the elderly. The study found that traffic-related air pollution is an additional risk factor for disease, such as bronchiolitis, asthma and middle ear infections in children. Although air pollution is a known risk factor for cardiovascular disease, relatively few studies have evaluated the effects of chronic exposures. Therefore, the BAQS is currently assessing the relationship between air quality and cardiovascular diseases in the Metro Vancouver area, with particular attention to the combined effects of traffic-related air pollution and noise pollution. Wood smoke was also found to be an important source of air pollution, even in urban centres. The study showed that building design and ventilation can help reduce infiltration of air pollutants into buildings. It was concluded that despite some concerns, the air quality in the Georgia-Basin-Puget Sound region is good compared to other major metropolitan areas. Air quality managers can use the study to evaluate different policy scenarios and the associated economic costs of air pollution. 5 figs.

    Full Text Available Aim: Diabetes Mellitus, a chronic progressive disorder, characterized with hyperglycemia and derangements of carbohydrate, protein and lipid metabolism. During its course microvascular, macrovascular and neurologic complications may develop. Being a patient with a chronic disorder like diabetes mellitus not only limits physical activities but also hinders other activities such as social life, education, career, occupational opportunities, and transportation, thus it influences individuals life quality unfavorably. Material and Method: Patient group with 229 individuals diagnosed with Type 2 DM and control group with 77 healthy individuals are involved in this study. A form questioning socio-demographic characteristics, past medical and family history and SF36 and EQ-5d life quality surveys are applied to individuals. 130 of the 306 people included in the study (42.5% in the group with complications, 99 (32.4% complications in the group, 77 (25.2% were in the control group.

    McIver, Jessica

    2012-01-01

    Data quality assessment plays an essential role in the quest to detect gravitational wave signals in data from the LIGO and Virgo interferometric gravitational wave detectors. Interferometer data contains a high rate of noise transients from the environment, the detector hardware, and the detector control systems. These transients severely limit the statistical significance of gravitational wave candidates of short duration and/or poorly modeled waveforms. This paper describes the data quality studies that have been performed in recent LIGO and Virgo observing runs to mitigate the impact of transient detector artifacts on the gravitational wave searches.

    Since the inception of the economic reform, marital relationship in urban China has undergone dramatic transformations. Though the burgeoning body of scholarly research has demonstrated that marital quality has increasingly become an important aspect of family life among married persons in urban China, both the conceptualization and measurement of marital quality remain underdeveloped. The purpose of this pilot study is to develop and validate a comprehensive and culturally appropriate marital quality scale, namely the Chinese Marital Quality Scale (CMQS). Results from the confirmatory factor analysis (CFA) conducted on a sample of 387 married persons from Beijing indicate that the CMQS can be conceptualized as a two-factorial and multidimensional construct, encompassing marital happiness, marital interaction, marital disagreement, marital problem, and marital instability. Additional statistical analyses also indicate that the CMQS has exhibited satisfactory reliability and concurrent validity. It is thus concluded that the CMQS is a reliable and valid instrument to measure marital quality in contemporary Beijing and possibly in other Chinese cities.

    In 2014, the U.S. Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) is assessing stream quality across the Piedmont and southern Appalachian Mountains in the southeastern United States. The goal of the Southeast Stream Quality Assessment (SESQA) is to characterize multiple water-quality factors that are stressors to aquatic life—contaminants, nutrients, sediment, and streamflow alteration—and the relation of these stressors to ecological conditions in streams throughout the region. Findings will provide communities and policymakers with information on which human and environmental factors are the most critical in controlling stream quality and, thus, provide insights about possible approaches to protect or improve stream quality. The SESQA study will be the second regional study by the NAWQA program, and it will be of similar design and scope as the Midwest Stream Quality Assessment conducted in 2013 (Van Metre and others, 2012).

    Smith, Clare; Williams, Emma; Bryan, Karen

    2017-07-01

    There have been calls for speech and language therapists (SLTs) to work within a public-health framework to support language development. Innovative practice is reported, but the range of services remains unknown. Furthermore, the potential impact of public health practice in speech and language therapy on early child development is also currently unknown. A new method in SLT research, systematic scoping reviews enable greater breadth of focus than traditional systematic reviews when identifying innovative practice. To report scope and critically appraise evidence of family-focused health-promotion practice for early language development in this area. Using the Cochrane Public Health Group scoping review framework, data from reports of health-promotion practice with families of children aged 0-3 years were extracted and critically appraised on service delivery, information, reach and evaluation. Group-based service delivery was the most popular form of service delivery. There were limited reports on the information given in services and on their reach. Questionnaires were the most popular reported evaluation method. Quality of evaluations was poor due to lack of replicability and experimental control in the studies reported. This method of systematic review has highlighted the scope of health-promotion practice in speech and language therapy and also demonstrated the lack of evidence for its effectiveness on child language development. It is argued that systematic scoping reviews are valuable for scoping innovative practice in areas where either there is a lack of robust evidence or there is a high level of heterogeneity in practice or evaluation. To support clinician appraisal of available evidence, recommendations are given for development of questionnaire appraisal and for categorization of evidence levels on summary databases. © 2016 Royal College of Speech and Language Therapists.

    Results of a scoping study to quantify the ex-vessel severe accident risks for the Swedish BWRs are reported. The study considers that a pool of water is established in the containment prior to vessel failure, as prescribed by the accident management scheme for the newer Swedish BWRs. The integrated methodology developed and employed combines probabilistic and deterministic treatment of the various melt-structure-water interaction processes occurring in sequence. The potential steam explosion, and the melt attack on the containment basemat, are treated with enveloping analyses. Uncertain parameters in the models and the initial conditions are treated with Monte Carlo simulations. Independent models are developed for melt coolability and possible attack on the concrete basemat. It is found that, with current models, the melt discharge scenarios, in which a large amount of accumulated melt may be released from the vessel, could subject the containment to large steam explosion loads. However, the uncertainties are so large that no definite conclusion can be drawn. The assessment of ex-vessel core debris coolability is disturbed by similar phenomenological uncertainties. Presently, coolability of the core debris can not be demonstrated. 133 refs.

    Full Text Available A complete definition of the scope of a project upfront during early stages ensures smooth and successful implementation during the project execution. This research identifies and prioritises project scope definition elements for public buildings in Saudi Arabia. Elements that could significantly contribute to complete project scope definition package at pre-project planning stage are identified and their interrelationship determined and prioritised. Using the Project Definition Rating Index (PDRI as a basis, the study uses analytical network process (ANP technique based on data obtained from project managers who have been involved in public sector projects in Saudi Arabia. Data collection and analysis was conducted in three steps. The first step involved identification of scope definition elements while the second involved an investigation into interrelationships among the elements. In the third step, ANP was used to determine the weight of the elements’ importance in terms of contribution to project scope definition completeness. Finally, Pareto analysis was used to prioritise and assess the distribution pattern of the elements. The outcome from this research is the prioritisation of project scope definition elements for public building projects in Saudi Arabia. The prioritised list developed indicates the importance of project scope definition elements. It should help project management teams identify elements to consider when evaluating project scope definition for completeness at the pre-project planning stage.

    The quality of cancer care may be compromised in the near future because of work force issues. Several factors will impact the oncology health provider work force: an aging population, an increase in the number of cancer survivors, and expansion of health care coverage for the previously uninsured. Between October 2014 and March 2015, an electronic literature search of English language articles was conducted using PubMed(®) , the Cumulative Index to Nursing and Allied Health Sciences (CINAHL(®) ), Web of Science, Journal Storage (JSTOR(®) ), Google Scholar, and SCOPUS(®) . Using the scoping review criteria, the research question was identified "How much care in oncology is provided by nurse practitioners (NPs)?" Key search terms were kept broad and included: "NP" AND "oncology" AND "workforce". The literature was searched between 2005 and 2015, using the inclusion and exclusion criteria, 29 studies were identified, further review resulted in 10 relevant studies that met all criteria. Results demonstrated that NPs are utilized in both inpatient and outpatient settings, across all malignancy types and in a variety of roles. Academic institutions were strongly represented in all relevant studies, a finding that may reflect the Accreditation Council for Graduate Medical Education (ACGME) duty work hour limitations. There was no pattern associated with state scope of practice and NP representation in this scoping review. Many of the studies reviewed relied on subjective information, or represented a very small number of NPs. There is an obvious need for an objective analysis of the amount of care provided by oncology NPs. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Given the severity and impact of the current Zika virus (ZIKV) outbreak in the Americas, numerous countries have rushed to develop research studies to assess ZIKV and its potential health consequences. In an effort to ensure that studies are comprehensive, both internally and externally valid, and with reliable results, the World Health Organization, the Pan American Health Organization, Institut Pasteur, the networks of Fiocruz, the Consortia for the Standardization of Influenza Seroepidemiology (CONSISE) and the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) have generated six standardized clinical and epidemiological research protocols and questionnaires to address key public health questions on ZIKV. We conducted a systematic search of ongoing study protocols related to ZIKV research. We analyzed the content of protocols of 32 cohort studies and 13 case control studies for systematic bias that could produce erroneous results. Additionally we aimed to characterize the risks of bias and confounding in observational studies related to ZIKV and to propose ways to minimize them, including the use of six newly standardized research protocols. Observational studies of ZIKV face an array of challenges, including measurement of exposure and outcomes (microcephaly and Guillain-Barré Syndrome). Potential confounders need to be measured where known and controlled for in the analysis. Selection bias due to non-random selection is a significant issue, particularly in the case-control design, and losses to follow-up is equally important for the cohort design. Observational research seeking to answer key questions on the ZIKV should consider these restrictions and take precautions to minimize bias in an effort to provide reliable and valid results. Utilization of the standardized research protocols developed by the WHO, PAHO, Institut Pasteur, and CONSISE will harmonize the key methodological aspects of each study design to minimize bias at

    The literature on strategies to increase the number of potential living kidney donors is extensive and has yet to be characterized. Scoping reviews are a novel methodology for systematically assessing a wide breadth of a given body of literature and may be done before conducting a more targeted systematic review. We performed a scoping review and summarized the evidence for existing strategies to increase living kidney donation. Our review identified seven studies that tested interventions using rigorous methods (i.e., randomized, controlled trials) and outcome measures, all of which focused on using education targeted at potential recipients to increase living donation. Of these, two studies that targeted the potential recipients' close social network reported statistically significant results. Other interventions were identified, but their effect was assessed through quasiexperimental or observational study designs. We identified an important gap in the literature for evidence-based strategies to increase living kidney donation. From the limited data available, strategies directed at potential recipients and their social networks are the most promising. These results can inform transplant programs that are considering strategies to increase living kidney donation and highlight the need for conduct of high-quality study to increase living donation.

    Pharmacology has traditionally been excluded from the mandatory application of good laboratory practice (GLP) principles. Consensus has been reached through the process of the International Conference on Harmonisation (ICH, Topic S7A) with regard to the definitions of the different types...... to encourage a positive attitude among researchers and academics towards these lines, whenever possible. GLP principles applied to the management of non-clinical safety studies are appropriate quality standards when studies are used in the context of protecting public health, and these quality standards...... be prepared to exercise flexibility in their requirement for GLP compliance, however, if non-clinical studies used in human safety assessment are not formally in compliance with the principles of GLP, regulatory acceptance may not be guaranteed.

  6. Quality and customer satisfaction: A case study in Brazil

    Science.gov (United States)

    Barcellos, Paulo Fernando Pinto

    The dissertation deals with the case of CEEE-Companhia Estadual de Energia Eletrica, an electric power utility located in Rio Grande do Sul, the southernmost state of Brazil. Customer satisfaction with the services provided by CEEE is investigated within three groups of consumers: residential, commercial, and industrial. The purpose of the dissertation is to find answers to the following research questions: (1) What is service quality in public utilities, and particularly in an electric power company? (2) What service quality dimensions do customers want to be provided and favor the most? (3) How does the market measure service quality? (4) What should be done by companies, and particularly by an electric utility monopoly, to increase the performance of the rendered service? (5) How does this impact customer satisfaction, retention, and intention to recommend? and (6) How do we start a company-wide quality program provided that the resources are scarce and therefore priorities should be set forth? To investigate the posed questions, the study begins with an exploratory survey of CEEE's Board. The survey is followed by qualitative research of the three customer groups. After qualitative analysis of the data is concluded, questionnaires for the quantitative research, as well as hypothetical models, are developed. Dillman's "Total Design Method" is used to design the questionnaires. The basic ACSI (American Customer Satisfaction Model) is used to approach customer satisfaction. Data are processed by PLS (Partial Least Squares) which follows the procedure developed at the National Quality Research Center of the University of Michigan Business School. In summary, commercial customers are the most dissatisfied with the services provided by CEEE, while residential customers are the most satisfied. To improve quality, priority should be placed on commercial customers and include efforts to improve productivity gains throughout the company. Also, CEEE's image should be

    2015-12-01

    The objectives of this study were twofold: to assess the demand for animal welfare education by open and distance learning (ODL) and to identify content to be covered in an ODL animal welfare programme. Through email, personal interviews and online surveys, data were collected from 161 respondents. The key survey questions were on: the need and reasons for providing animal welfare education through ODL; entry-level qualifications; job/career prospects; duration of the programme, and suggestions on course content. The majority of respondents felt that there was a need for a one-year ODL academic programme on animal welfare. In the light of the findings of this study and related discussions, the authors recommend that online and ODL programmes in animal welfare be developed to meet the continuing educational needs of veterinary students, working veterinarians, para-veterinarians and other stakeholders closely related to animal welfare.

  12. Enhanced scope of a Phase 2 CMS detector for the study of exotic physics signatures at the HL-LHC

    CERN Document Server

    CMS Collaboration

    2016-01-01

    The high luminosity LHC (HL-LHC) run, which is due to start in 2025, is expected to collect an integrated luminosity of approximately $3000~\\mathrm{fb}^{-1}$ at $\\sqrt{s}=14~\\mathrm{TeV}$. The discovery and study of physics beyond the standard model will remain one of the major goals of the CMS collaboration during this period. Such physics can yield exotic signatures, whose observation places unusual demands on the performance and capabilities of the detector. For a few selected exotic physics models, we present studies of what can be achieved using CMS data during the HL-LHC run. We look at how this potential is influenced by the design of the upgraded CMS detector, as documented in the $\\mathrm{phase~2}$ technical proposal. This document provides supplementary material for a deeper level of understanding of these studies. In the case of a high mass resonance decaying to leptons, we explore the hypothesis that this is discovered prior to 2025, and examine what would be learned about the resonance's properti...

    Objectives Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data. Design Case series. Setting The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States. Participants Acute myocardial infarction cases (72) occurring between 1/1/2001 and 12/31/2006 were identified from a cohort of 4549 participants. Outcome measures The proportion of cases that were provided standard quality of care therapy, as defined by the Healthcare Financing Administration and other national organizations. Results The provision of quality services, such as administration of aspirin on admission and at discharge, reperfusion therapy within 24 hours, prescription of beta blocker medication at discharge, and smoking cessation counseling were found to be 94%, 91%, 92%, 86% and 71%, respectively. The unadjusted, 30 day mortality rate was 17%. Conclusion Despite considerable challenges posed by geographic isolation and small facilities, process measures of the quality of acute myocardial infarction care for participants in this American Indian cohort were comparable to that reported for Medicare beneficiaries nationally and within the resident states of this cohort.

    Full Text Available High-quality data are the precondition for analyzing and using big data and for guaranteeing the value of the data. Currently, comprehensive analysis and research of quality standards and quality assessment methods for big data are lacking. First, this paper summarizes reviews of data quality research. Second, this paper analyzes the data characteristics of the big data environment, presents quality challenges faced by big data, and formulates a hierarchical data quality framework from the perspective of data users. This framework consists of big data quality dimensions, quality characteristics, and quality indexes. Finally, on the basis of this framework, this paper constructs a dynamic assessment process for data quality. This process has good expansibility and adaptability and can meet the needs of big data quality assessment. The research results enrich the theoretical scope of big data and lay a solid foundation for the future by establishing an assessment model and studying evaluation algorithms.

    Interaction through online social networks potentially results in the contestation of prevailing ideas about health and health care, and to mass protest where health is put at risk or health care provision is wanting. Through a review of the academic literature and case studies of four social networking health sites (PatientsLikeMe, Mumsnet, Treatment Action Campaign, and My Pro Ana), we establish the extent to which this phenomenon is documented, seek evidence of the prevalence and character of health-related networks, and explore their structure, function, participants, and impact, seeking to understand how they came into being and how they sustain themselves. Results indicate mass protest is not arising from these established health-related networking platforms. There is evidence of changes in policy following campaigning activity prompted by experiences shared through social networking such as improved National Health Service care for miscarriage (a Mumsnet campaign). Platform owners and managers have considerable power to shape these campaigns. Social networking is also influencing health policy indirectly through increasing awareness and so demand for health care. Transient social networking about health on platforms such as Twitter were not included as case studies but may be where the most radical or destabilizing influence on health care policy might arise.

    Lang, Moritz; Rudolf, Fabian; Stelling, Jörg

    2012-04-01

    Complex microscopy protocols, e.g., to dynamically track multiple signals in living cells under different conditions, are becoming more common. However, the implementation of complex protocols on modern, motorized microscopes often requires their reformulation into low-level machine language. This recoding is a time-consuming and error-prone task that often requires advanced programming skills. This unit describes how to use the high level, open-source microscope control platform YouScope to implement complex measurement protocols. Three protocols detail how to install and configure YouScope on a motorized microscope, how to use YouScope to quickly assess the quality of a sample, and how to set up imaging protocols for cells in a microplate. In addition to these protocols, descriptions are given for the use of various other tools YouScope provides to successfully accomplish various microscopy tasks.

    The present investigations in the vicinity of the Sellafield potential repository zone have provided data on groundwater pressure and salinity to a depth of some 2000 m, for a section extending from the hills to the east of the zone, to the coast. As part of the process of demonstrating the suitability of the site for a deep repository, work has been undertaken to reconcile these observations of pressure and salinity with an understanding of the hydrogeology of the site. It is considered possible that the long glacial history of the site may in part be responsible for present observations. This work documents some preliminary studies to determine the possible magnitude of such glacial effects. 4 refs, 2 figs.

    Green (vegetated) roofs are emerging as practical strategies to improve the environmental quality of cities. However, the impact of green roofs on the storm water quality remains a topic of concern to city planners and environmental policy makers. This study investigated whether green roofs act as a source or a sink of various metals (Na, K, Ca, Mg, Al, Fe, Cu, Cd, Pb, Zn, Mn, Cr, Ni, Li and Co), inorganic anions (NO3-, NO2-, PO4(3-), SO4(2-), Cl-, F- and Br-) and cation (NH4+). A series of green roof assemblies were constructed. Four different real rain events and several artificial rain events were considered for the study. Results showed that concentrations of most of the chemical components in runoff were highest during the beginning of rain events and subsided in the subsequent rain events. Some of the important components present in the runoff include Na, K, Ca, Mg, Li, Fe, Al, Cu, NO3-, PO4(3-) and SO4(2-). However, the concentration of these chemical components in the roof runoff strongly depends on the nature of substrates used in the green roof and the volume of rain. Based on the USEPA standards for freshwater quality, we conclude that the green roof used in this study is reasonably effective except that the runoff contains significant amounts of NO3- and PO4(3-).

    Among the biomonitors of environmental quality, there is a lack of studies on using invertebrates to evaluate quantitatively chemical elements in ecosystems. This group of animals is quite numerous, widely distributed and adaptable to the most diverse environmental conditions. These features are very useful for the environmental quality assessment, as well as the several occurring insect-plant interactions performing essential functions in ecosystems. The objective of this work is to study the variability of chemical composition of invertebrate orders for using in environmental quality monitoring studies. Instrumental neutron activation analysis - INAA was applied to determine some nutrients and trace elements in invertebrate samples. Sampling by pitfall traps was carried out in riverine ecosystems from the urban area from the Piracicaba Municipality, State of Sao Paulo, Brazil. Invertebrate and reference material samples were irradiated in the nuclear research reactor IEA-R1, Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN. Fragments of a Ni-Cr alloy were irradiated for monitoring the thermal neutron flux. Hymenoptera order was considered the most representative according to the total number of sampled species (about 60%). Significant amounts of Ba, Br, Fe and Sc were found in invertebrates of the order Opiliones. Potassium, rubidium and zinc were highly accumulated in species from Blattodea order, indicating a consistent pattern of accumulation for this invertebrate order. Taking into account the abundance of Hymenoptera order, the chemical composition of its species was significant different at the 95% confidence level for Br and Na in the sampled locals. (author)

    Full Text Available Aquaponic systems are integrated systems that combine fish farming and different types of plants. It involves a dynamic interaction between fish plants and bacteria. Fish and plants are dependent the equilibrium of dissolved nutrients and water quality. Only by striking a balance between dissolved nutrients and water quality we can achieve a large production of plants and healthy fish. Thus, control of water quality in an aquaponic system is essential in order to obtain performance in raising fish and plants. The experiment was conducted in the laboratory of Fisheries and Aquaculture of the Faculty of Animal Science of the University of Agronomic Sciences and Veterinary Medicine of Bucharest within a period of 30 days. The system used for the experiment was designed and developed in the laboratory mentioned above. The plant used for water treatment in the system was basil (Ocimum basilicum. Fish species grown in the system was culture carp (Cyprinus carpio. Indicators measured to assess water quality in the system were: temperature, pH, dissolved oxygen, total ammonia, nitrites, nitrates and phosphates. The values determined pH 7.4-7.6, dissolved oxygen 8-10 mg / l, NH4 0.05-05 mg/ l, NO2 0.1-3.2 mg / l, NO3 0-80 mg / l, 0.02-0.3 mg, PO4 0.02-0.3 mg/l were not too high. In conclusion it was demonstrated that water quality in the aquaponic system studied is propitious to the growth and welfare of fish the registered values are not to be harmful.

    Through collecting the spectral signals of TIG and MIG welding arc with spectrometer, the arc light radiations were analyzed based on the basic theory of plasma physics. The radiation of welding arc distributes over a broad range of frequency, from infrared to ultraviolet. The arc spectrum is composed of line spectra and continuous spectra. Due to the variation of metal density in the welding arc, there is great difference between the welding arc spectra of TIG and MIG in both their intensity and distribution. The MIG welding arc provides more line spectra of metal and the intensity of radiation is greater than TIG. The arc spectrum of TIG welding is stable during the welding process, disturbance factors that cause the spectral variations can be reflected by the spectral line related to the corresponding element entering the welding arc. The arc spectrum of MIG welding will fluctuate severely due to droplet transfer, which produces "noise" in the line spectrum aggregation zone. So for MIG welding, the spectral zone lacking spectral line is suitable for welding quality diagnosis. According to the characteristic of TIG and MIG, special spectral zones were selected for welding quality diagnosis. For TIG welding, the selected zone is in ultraviolet zone (230-300 nm). For MIG welding, the selected zone is in visible zone (570-590 nm). With the basic theory provided for welding quality diagnosis, the integral intensity of spectral signal in the selected zone of welding process with disturbing factor was studied to prove the theory. The results show that the welding quality and disturbance factors can be diagnosed with good signal to noise ratio in the selected spectral zone compared with signal in other spectral zone. The spectral signal can be used for real-time diagnosis of the welding quality.

    During the past three years, working with more than 150 organizations representing public and private stakeholders, EPRI has developed the Electricity Technology Roadmap. The Roadmap identifies several major strategic challenges that must be successfully addressed to ensure a sustainable future in which electricity continues to play an important role in economic growth. Articulation of these anticipated trends and challenges requires a detailed understanding of the role and importance of reliable electricity in different sectors of the economy. This report is intended to contribute to that understanding by analyzing key aspects of trends in the economic value of electricity reliability in the U.S. economy. We first present a review of recent literature on electricity reliability costs. Next, we describe three distinct end-use approaches for tracking trends in reliability needs: (1) an analysis of the electricity-use requirements of office equipment in different commercial sectors; (2) an examination of the use of aggregate statistical indicators of industrial electricity use and economic activity to identify high reliability-requirement customer market segments; and (3) a case study of cleanrooms, which is a cross-cutting market segment known to have high reliability requirements. Finally, we present insurance industry perspectives on electricity reliability as an example of a financial tool for addressing customers' reliability needs.

    2016-09-01

    We present a study focusing on detection and initial quantitative estimates of ethylene (C2H4) in observations from the Tropospheric Emission Spectrometer (TES), a Fourier transform spectrometer aboard the Aura satellite that measures thermal infrared radiances with high spectral resolution (0.1 cm-1). We analyze observations taken in support of the 2008 Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission and demonstrate the feasibility of future development of C2H4 into a TES standard product. In the Northern Hemisphere, C2H4 is commonly associated with boreal fire plumes, motor vehicle exhaust and petrochemical emissions. It has a short lifetime (∼14-32 h) in the troposphere due to its reaction with OH and O3. Chemical destruction of C2H4 in the atmosphere leads to the production of ozone and other species such as carbon monoxide (CO) and formaldehyde. Results indicate a correlation between C2H4 and CO in boreal fire plumes. Quantitative C2H4 estimates are sensitive to assumptions about the plume height and width. We find that C2H4 greater than 2-3 ppbv can be detected in a single TES observation (for a fire plume at 3 km altitude and 1.5 km width). Spatial averaging will be needed for surface-peaking profiles where TES sensitivity is lower.

    The purpose of this project was to evaluate the ability of advanced low rank coal gasification technology to cause a significant reduction in the COE for IGCC power plants with 90% carbon capture and sequestration compared with the COE for similarly configured IGCC plants using conventional low rank coal gasification technology. GE’s advanced low rank coal gasification technology uses the Posimetric Feed System, a new dry coal feed system based on GE’s proprietary Posimetric Feeder. In order to demonstrate the performance and economic benefits of the Posimetric Feeder in lowering the cost of low rank coal-fired IGCC power with carbon capture, two case studies were completed. In the Base Case, the gasifier was fed a dilute slurry of Montana Rosebud PRB coal using GE’s conventional slurry feed system. In the Advanced Technology Case, the slurry feed system was replaced with the Posimetric Feed system. The process configurations of both cases were kept the same, to the extent possible, in order to highlight the benefit of substituting the Posimetric Feed System for the slurry feed system.

    We compare laryngoscopic quality and time to highest-grade view between a face-to-face approach with the GlideScope and traditional flexible fiber-optic laryngoscopy in awake, upright volunteers. This was a prospective, randomized, crossover study in which we performed awake laryngoscopy under local anesthesia on 23 healthy volunteers, using both a GlideScope video laryngoscopy face-to-face technique with the blade held upside down and flexible fiber-optic laryngoscopy. Operator reports of Cormack-Lehane laryngoscopic views and video-reviewed time to highest-grade view, as well as number of attempts, were recorded. Ten women and 13 men participated. A grade II or better view was obtained with GlideScope video laryngoscopy in 22 of 23 (95.6%) participants and in 23 of 23 (100%) participants with flexible fiber-optic laryngoscopy (relative risk GlideScope video laryngoscopy versus flexible fiber-optic laryngoscopy 0.96; 95% confidence interval 0.88 to 1.04). Median time to highest-grade view for GlideScope video laryngoscopy was 16 seconds (interquartile range 9 to 34) versus 51 seconds (interquartile range 35 to 96) for flexible fiber-optic laryngoscopy. A distribution of interindividual differences demonstrated that GlideScope video laryngoscopy was, on average, 39 seconds faster than flexible fiber-optic laryngoscopy (95% confidence interval 0.2 to 76.9 seconds). GlideScope video laryngoscopy can be used to obtain a Cormack-Lehane grade II or better view in the majority of awake, healthy volunteers when an upright face-to-face approach is used and was slightly faster than traditional flexible fiber-optic laryngoscopy. However, flexible fiber-optic laryngoscopy may be more reliable at obtaining high-grade views of the larynx. Awake, face-to-face GlideScope use may offer an alternative approach to the difficulty airway, particularly among providers uncomfortable with flexible fiber-optic laryngoscopy.

    Transition metal-catalyzed amination of allylic compounds via a pi-allylmetal intermediate is a powerful and useful method for synthesizing allylamines. Direct catalytic substitution of allylic alcohols, which forms water as the sole coproduct, has recently attracted attention for its environmental and economical advantages. Here, we describe the development of a versatile direct catalytic amination of both aryl- and alkyl-substituted allylic alcohols with various amines using Pt-Xantphos and Pt-DPEphos catalyst systems, which allows for the selective synthesis of various monoallylamines, such as the biologically active compounds Naftifine and Flunarizine, in good to high yield without need for an activator. The choice of the ligand was crucial toward achieving high catalytic activity, and we demonstrated that not only the large bite-angle but also the linker oxygen atom of the Xantphos and DPEphos ligands was highly important. In addition, microwave heating dramatically affected the catalyst activity and considerably decreased the reaction time compared with conventional heating. Furthermore, several mechanistic investigations, including (1)H and (31)P{(1)H} NMR studies; isolation and characterization of several catalytic intermediates, Pt(xantphos)Cl(2), Pt(eta(2)-C(3)H(5)OH)(xantphos), etc; confirmation of the structure of [Pt(eta(3)-allyl)(xantphos)]OTf by X-ray crystallographic analysis; and crossover experiments, suggested that formation of the pi-allylplatinum complex through the elimination of water is an irreversible rate-determining step and that the other processes in the catalytic cycle are reversible, even at room temperature.

    We examined the feasibility of engaging women collectives in delivering a package of women's nutrition messages/services as a funded stakeholder in three tribal-dominated districts of Odisha, Jharkhand and Chhattisgarh States, in eastern India. These districts have high prevalence of child stunting and poor government service outreach. Conducted between July 2014 and March 2015, an exploratory mix-methods design was adopted (review of coverage data and government reports, field interviews and focus group discussion with multiple stakeholders and intended communities) to assess coverage of women's nutrition services. A capacity assessment tool was developed to map all types of community collectives and assess their awareness, institutional and programme capacity as a funded stakeholder for delivering women's nutrition services/behaviour promotion. Limited targeting of pre-pregnancy period, delays in first trimester registration of pregnant women, and low micronutrient supplementation supply and awareness issues emerged as key bottlenecks in improving women's nutrition in these districts. Amongst the 18 different types of community collectives mapped, Self Help Groups (SHGs) and their federations (tier 2 and tier 3), with total membership of over 650,000, emerged as the most promising community collective due to their vast network, governance structure, bank linkage, and regular interface. Nearly 400,000 (or 20% of women) in these districts can be reached through the mapped 31,919 SHGs. SHGs with organisational readiness for receiving and managing grants for income generation and community development activities varied from 41 to 94% across study districts. Stakeholders perceived that SHGs federations managing grants from government and be engaged for nutrition promotion and service delivery and SHG weekly meetings can serve as community interface for discussing/resolving local issues impeding access to services. Women SHGs (with tier 2 and tier 3) can become direct

    The primary objective of the present study is to identity the most promising, viable technologies that are likely to culminate in an expedited development of the next-generation, field-deployable instrument for providing rapid, accurate, and precise enrichment assay of uranium hexafluoride (UF6). UF6 is typically involved, and is arguably the most important uranium compound, in uranium enrichment processes. As the first line of defense against proliferation, accurate analytical techniques to determine the uranium isotopic distribution in UF6 are critical for materials verification, accounting, and safeguards at enrichment plants. As nuclear fuel cycle technology becomes more prevalent around the world, international nuclear safeguards and interest in UF6 enrichment assay has been growing. At present, laboratory-based mass spectrometry (MS), which offers the highest attainable analytical accuracy and precision, is the technique of choice for the analysis of stable and long-lived isotopes. Currently, the International Atomic Energy Agency (IAEA) monitors the production of enriched UF6 at declared facilities by collecting a small amount (between 1 to 10 g) of gaseous UF6 into a sample bottle, which is then shipped under chain of custody to a central laboratory (IAEA’s Nuclear Materials Analysis Laboratory) for high-precision isotopic assay by MS. The logistics are cumbersome and new shipping regulations are making it more difficult to transport UF6. Furthermore, the analysis is costly, and results are not available for some time after sample collection. Hence, the IAEA is challenged to develop effective safeguards approaches at enrichment plants. In-field isotopic analysis of UF6 has the potential to substantially reduce the time, logistics and expense of sample handling. However, current laboratory-based MS techniques require too much infrastructure and operator expertise for field deployment and operation. As outlined in the IAEA Department of Safeguards Long

    It has been argued that respondents in contingent valuation (CV) surveys, asked to value complex environmental amenities, will state willingness to pay (WTP) independently of the scope of the project. Such insensitivity to scope would be at odds with rational choice, and could therefore imply that CV is not a theoretically valid method for biodiversity valuation. The scope test in the present CV study was applied to endangered species preservation. Respondents were split in four sub-samples facing different scopes of endangered species preservation. The design allowed for both external and internal scope tests. Furthermore, the tests were split according to elicitation format. Of four external tests of insensitivity to scope, one was rejected, two gave mixed results, depending on either the type of test or elicitation format, and for the last one the null hypothesis could not be rejected. Of five internal tests, insensitivity to scope was rejected in three cases, one test gave mixed results, and one could not be rejected. Survey design features of the CV study, especially an unfamiliar sub-group of endangered species, could explain the apparent insensitivity to scope observed.

    In urban cities, the environmental services are the responsibility of the public sector, where piped water supply is the norm for urban household. Likewise, in Beirut City (capital of Lebanon) official water authorities are the main supplier of domestic water through a network of piping system that leaks in many areas. Beirut City and its suburbs are overpopulated since it is the residence of 1/3 of the Lebanese citizens. Thus, Beirut suffers deficiency in meeting its water demand. Water rationing, as a remedial action, is firmly established since four decades by the Lebanese Water Authorities. Consumers resorted then to private wells to supplement their domestic water needs. Consequently, household water quality is influenced by external factors relating to well water characteristics and internal factors depending on the types of the pipes of the distribution network and cross connections to sewer pipes. These factors could result in chemical and microbial contamination of drinking water. The objective of this study is to investigate domestic water quality variation in Beirut City emerging form the aforementioned factors. The presented work encircles a typical case study of Beirut City (Ras Beirut). Results showed deterioration pattern in domestic water quality. The predicted metal species and scales within the water pipes of distribution network depended on water pH, hardness, sulfate, chloride, and iron. The corrosion of iron pipes mainly depended on Mg hardness.

    Full Text Available Marketing is a philosophy that leads to the process by which organizations, groups and individuals obtain what they need and want by identifying value, providing it, communicating it and delivering it to others. The core concepts of marketing are customers needs, wants and values; products, exchange, communications and relationships. Marketing is strategically concerned with the direction and scope of the long-term activities performed by the organization to obtain a competitive advantage. The organization applies its resources within a changing environment to satisfy customer needs while meeting stakeholder expectations. Implied in this view of strategic marketing is the requirement to develop a strategy to cope with competitors, identify market opportunities, develop and commercialize new products and services, allocate resources among marketing activities and design an appropriate organizational structure to ensure the perform once desired is achieved.

    This study is a qualitative, descriptive study of how registered nurses (RNs) (N=33) in leadership roles in institutionalized long-term care settings delegate care, including their strategies and processes for delegating care, and their perceptions of barriers to effective delegation and potential benefits of delegation. Findings indicate two key approaches to delegation, including the "follow the job description" approach, emphasizing adherence to facility-level roles and job descriptions, and the "consider the scope of practice" approach, emphasizing consideration of multiple aspects of scope of practice and licensure, and the context of care. While the former resulted in more clarity and certainty for the RN, the latter facilitated a focus on quality of resident care outcomes as linked to the delegation process. Barriers to effective delegation were comparable among RNs using either approach to delegation, and almost all RNs could describe benefits of delegation for long-term care.

    More than half of all cases of preeclampsia occur in healthy first-time pregnant women. Our aim was to develop a method to predict those at risk by combining clinical factors and measurements of biomarkers in women recruited to the Screening for Pregnancy Endpoints (SCOPE) study of low-risk nulliparous women. Forty-seven biomarkers identified on the basis of (1) association with preeclampsia, (2) a biological role in placentation, or (3) a role in cellular mechanisms involved in the pathogenesis of preeclampsia were measured in plasma sampled at 14 to 16 weeks' gestation from 5623 women. The cohort was randomly divided into training (n=3747) and validation (n=1876) cohorts. Preeclampsia developed in 278 (4.9%) women, of whom 28 (0.5%) developed early-onset preeclampsia. The final model for the prediction of preeclampsia included placental growth factor, mean arterial pressure, and body mass index at 14 to 16 weeks' gestation, the consumption of ≥3 pieces of fruit per day, and mean uterine artery resistance index. The area under the receiver operator curve (95% confidence interval) for this model in training and validation cohorts was 0.73 (0.70-0.77) and 0.68 (0.63-0.74), respectively. A predictive model of early-onset preeclampsia included angiogenin/placental growth factor as a ratio, mean arterial pressure, any pregnancy loss preeclampsia in populations of mixed parity and risk. In nulliparous women, combining multiple biomarkers and clinical data provided modest prediction of preeclampsia. © 2014 American Heart Association, Inc.

    The mission of NOAA's Geostationary Operational Environmental Satellite System (GOES) R series satellites, in the 2012 time frame, is to provide continuous, near real-time meteorological, oceanographic, solar, and space environment data that supports NOAA's strategic mission goals. It presents an exciting opportunity to explore new instruments, satellite designs, and system architectures utilizing new communication and instrument technologies in order to meet the ever-increasing demands made of Earth observation systems by national agencies and end users alike. The GOES-R sensor suite includes a 16 spectral band Advanced Baseline Imager (ABI), an approximately 1500 high spectral resolution band Hyperspectral Environmental Suite (HES), plus other sensors designed to detect lightning and to explore the ocean, solar and space environment. The Cooperative Institute for Meteorological Satellite Studies (CIMSS) as part of the Space Science and Engineering Center (SSEC) of the University of Wisconsin-Madison, the long time partner of NOAA, has developed the first operational end-to-end processing system for GOES. Based on this heritage, and with recent support from the NASA/NOAA Geosynchrous Imaging FTS (GIFTS) project, the Navy's Multiple University Research Initiative (MURI), and NOAA's GOES-R Risk Reduction program, SSEC has built a near-complete end-to-end system that is capable of simulating sensor measurements from top of atmosphere radiances, raw sensor data (level 0) through calibrated and navigated sensor physical measurements (level 1) to the processed products (level 2). In this paper, the SSEC Hyperspectral Imaging and Sounding Simulator and Processor (HISSP) will be presented in detail. HISSP is capable of demonstrating most of the processing functions such as data compression/decompression, sensor calibration, data processing, algorithm development, and product generation. In summary, HISSP is an end-to-end system designed to support both government and

    Agriculture, rapid urbanization and geochemical processes have direct or indirect effects on the chemical composition of groundwater and aquifer geochemistry. Hydro-chemical investigations, which are significant for assessment of water quality, were carried out to study the sources of dissolved ions in groundwater of Dinajpur district, northern Bangladesh. The groundwater samplish were analyzed for physico-chemical properties like pH, electrical conductance, hardness, alkalinity, total dissolved solids and Ca2+, Mg2+, Na+, K+, CO3(2-), HCO3(-), SO4(2-) and Cl- ions, respectively. Based on the analyses, certain parameters like sodium adsorption ratio, soluble sodium percentage, potential salinity, residual sodium carbonate, Kelly's ratio, permeability index and Gibbs ratio were also calculated. The results showed that the groundwater of study area was fresh, slightly acidic (pH 5.3-6.4) and low in TDS (35-275 mg I(-1)). Ground water of the study area was found suitable for irrigation, drinking and domestic purposes, since most of the parameters analyzed were within the WHO recommended values for drinking water. High concentration of NO3- and Cl- was reported in areas with extensive agriculture and rapid urbanization. Ion-exchange, weathering, oxidation and dissolution of minerals were major geochemical processes governing the groundwater evolution in study area. Gibb's diagram showed that all the samples fell in the rock dominance field. Based on evaluation, it is clear that groundwater quality of the study area was suitable for both domestic and irrigation purposes.

    Satellite instruments have had great success in monitoring the stratospheric ozone and in understanding the processes that control its daily to decadal scale variations. This field is now reaching its zenith with a number of satellite instruments from the US, Europe and Canada capping several decades of active research in this field. The primary public policy imperative of this research was to make reliable prediction of increases in biologically active surface UV radiation due to human activity. By contrast retrieval from satellite data of atmospheric constituents and photo-chemically active radiation that affect air quality is a new and growing field that is presenting us with unique challenges in measurement and data interpretation. A key distinction compared to stratospheric sensors is the greatly enhanced role of clouds, aerosols, and surfaces (CAS) in determining the quality and quantity of useful data that is available for air quality research. In our presentation we will use data from several sensors that are currently flying on the A-train satellite constellation, including OMI, MODIS, CLOUDSAT, and CALIPSO, to highlight that CAS can have both positive and negative effects on the information content of satellite measurements. This is in sharp contrast to other fields of remote sensing where CAS are usually considered an interference except in those cases when they are the primary subject of study. Our analysis has revealed that in the reflected wavelengths one often sees much further down into the atmosphere, through most cirrus, than one does in the emitted wavelengths. The lower level clouds provide a nice background against which one can track long-range transport of trace gases and aerosols. In addition, differences in trace gas columns estimated over cloudy and adjacent clear pixels can be used to measure boundary layer trace gases. However, in order to take full advantage of these features it will be necessary to greatly advance our understanding of

    We report the findings of a knowledge synthesis research project on the topic of dementia-friendly acute care (D-FAC) design. This exploratory project systematically mapped what is known about D-FAC physical design in hospitals. We discuss our challenges in locating reportable evidence and the implications of such design for maximizing independent function while ensuring safety and harm reduction in older people living with dementia. Exploratory iterative design utilizing scoping literature review methodology. A total of 28 primary studies plus expert reviewers' narratives on the impact of design and architectural features on independent function of hospitalized older people with dementia were included and evaluated. Items were mapped to key design elements to describe a D-FAC environment. This scoping review project confirms the limited nature of available acute care design evidence on maximizing function. Physical design influences the usability and activity undertaken in a health care space and ultimately affects patient outcomes. Achieving safe quality hospital care for older people living with dementia is particularly challenging. Evidence of design principle effectiveness is needed that can be applied to general medical and surgical units where the bulk of older persons with and without dementia are treated.

  6. Using SCOPE to identify potential regulatory motifs in coregulated genes.

    2011-05-31

    SCOPE is an ensemble motif finder that uses three component algorithms in parallel to identify potential regulatory motifs by over-representation and motif position preference. Each component algorithm is optimized to find a different kind of motif. By taking the best of these three approaches, SCOPE performs better than any single algorithm, even in the presence of noisy data. In this article, we utilize a web version of SCOPE to examine genes that are involved in telomere maintenance. SCOPE has been incorporated into at least two other motif finding programs and has been used in other studies. The three algorithms that comprise SCOPE are BEAM, which finds non-degenerate motifs (ACCGGT), PRISM, which finds degenerate motifs (ASCGWT), and SPACER, which finds longer bipartite motifs (ACCnnnnnnnnGGT). These three algorithms have been optimized to find their corresponding type of motif. Together, they allow SCOPE to perform extremely well. Once a gene set has been analyzed and candidate motifs identified, SCOPE can look for other genes that contain the motif which, when added to the original set, will improve the motif score. This can occur through over-representation or motif position preference. Working with partial gene sets that have biologically verified transcription factor binding sites, SCOPE was able to identify most of the rest of the genes also regulated by the given transcription factor. Output from SCOPE shows candidate motifs, their significance, and other information both as a table and as a graphical motif map. FAQs and video tutorials are available at the SCOPE web site which also includes a "Sample Search" button that allows the user to perform a trial run. Scope has a very friendly user interface that enables novice users to access the algorithm's full power without having to become an expert in the bioinformatics of motif finding. As input, SCOPE can take a list of genes, or FASTA sequences. These can be entered in browser text fields, or read from

    The beam quality of uncoupled laser diode array is studied theoretically and experimentally. By calculating the second order moments of the beam emitted from the laser diode array, the dependence of the M2-factor of the laser diode array on the M2-factor of the single emitter, the ratio of the emitting region to the non-emitting space, and the number of emitters, has been deduced. From the measurement of the beam propagation the M2-factor of a laser diode bar is experimentally determined. The measured M2-factor of the laser diode bar agrees with the theoretical prediction.

    Air pollution is one of the main factors that affect the air quality in aircraft cabins, and the use of different air supply modes could influence the distribution of air pollutants in cabins. Based on the traditional ceiling air supply mode used on the B737NG, this study investigated another 3 different kinds of air supply modes for comparison: luggage rack air supply mode, joint mode combining ceiling and luggage rack air supply, and joint mode combining ceiling and individual air supply. Under the above 4 air supply modes, the air velocity, temperature and distribution of air pollutants in a cabin full of passengers were studied using computational fluid dynamics (CFD), and carbon dioxide (CO2) and formaldehyde were selected as 2 kinds of representative air pollutants. The simulation results show that the joint mode combining ceiling and individual air supply can create a more uniform distribution of air velocity and temperature, has a better effect on the removal of CO2 and formaldehyde, and can provide better air quality in cabins than the other 3 modes.

Methods: This hospital-based cross-sectional study was conducted in the Department of Dermatology, JIPMER, Pondicherry, India. Clinical severity, physical and psychosocial morbidity, and the stress incurred were measured using psoriasis area severity index (PASI, psoriasis disability index (PDI, and psoriasis life stress inventory (PLSI respectively, the latter two of which were suitably modified and translated into the local language, viz., Tamil. Appropriate tests were conducted using SPSS for Windows (Release 7.5.1 statistical software. Results: Fifty patients (34 males, 16 females were included in the study. The clinical PASI scores correlated significantly with the overall physical disability (PDI, individual aspects of the PDI (except the treatment-related activities, and the measurement of stress incurred (PLSI. A PASI score of more than 18 delineated a subgroup of patients with higher overall physical disability and higher stress rating. Among the physical and psychosocial factors investigated, daily activities, employment, and treatment were reported to be affected the most. Psoriasis sufferers are also most likely to feel self-conscious, be disturbed / inconvenienced by the shedding of the skin, live in a constant fear of relapse, and avoid social interactions. Conclusions: The present study provides compelling evidence that psoriasis affects the quality of life, and it highlights the importance of adopting a multidimensional assessment of psoriasis.

Its role in diagnosing soft tissue tumors (STT has been fairly documented, as well as debated. Present study was aimed at evaluating its scope in diagnosing 127 cases of soft tissue tumors. Methods Conventional Pap and MGG staining was available in all the cases. Immunocytochemistry (ICC was performed in 15 cases. Histopathological details were available in 115 cases. Results 50% cases were referred for a primary diagnosis, while 26.8% & 22.8% cases were evaluated for recurrent and metastatic lesions, respectively. Extremities were the commonest sites. On FNAC, 101 cases (79.5% were labeled as malignant, whereas 10 cases (7.9% were labeled as benign. The remaining 16 cases (11% were not categorized and were labeled as 'unsure/not specified'. Histopathological confirmation in 115 cases, gave a diagnostic accuracy of 98%, with a positive predictive value of 98% in malignant cases and a negative predictive value of 100% in benign cases. Two cases were false positive. Among the various cytological categories, 60 cases (47.2% were of spindle cell type, followed by 32 (25.2% of round cell type and 14 cases (11% of lipomatous type. Other 12 cases (9.4% were of pleomorphic type; 7 (5.5% cases of epithelioid type and remaining 2 cases were of myxoid type. All the round cell, pleomorphic and myxoid type of tumors were sarcomas, whereas 73.3% cases of spindle cell type were labeled as 'malignant'. Exact cytological sub typing was offered in 58 cases, with rhabdomyosarcoma (RMS as the most frequently sub typed tumor. The two false positive malignant cases were of fibromatosis and a pigmented schwannoma, on biopsy. Out of 28 metastatic lesions, lymph nodes were the commonest site for metastasis, with epithelioid tumors that formed highest percentage of metastatic cases.

    Tamimi, Abdallah Ibrahim

    Quality management is a fundamental challenge facing businesses. This research attempted to quantify the effect of quality investment on the Cost of Poor Quality (COPQ) in an aerospace company utilizing 3 years of quality data at United Launch Alliance, a Boeing -- Lockheed Martin Joint Venture Company. Statistical analysis tools, like multiple regressions, were used to quantify the relationship between quality investments and COPQ. Strong correlations were evident by the high correlation coefficient R2 and very small p-values in multiple regression analysis. The models in the study helped produce an Excel macro that based on preset constraints, optimized the level of quality spending to minimize COPQ. The study confirmed that as quality investments were increased, the COPQ decreased steadily until a point of diminishing return was reached. The findings may be used to develop an approach to reduce the COPQ and enhance product performance. Achieving superior quality in rocket launching enhances the accuracy, reliability, and mission success of delivering satellites to their precise orbits in pursuit of knowledge, peace, and freedom while assuring safety for the end user.

    This study examined whether individuals with different personality types (i.e., overcontrollers, undercontrollers, resilients) had different friendship quality development throughout adolescence. It also investigated whether personality types were indirectly related to romantic relationship quality in young adulthood, via friendship quality development in adolescence. The study employed six waves of longitudinal questionnaire data from Dutch youths who had a romantic relationship when they were young adults. Two age cohorts were followed, from 12 to 21 years and from 16 to 25 years, respectively. Findings showed that resilients reported higher mean levels of friendship quality during adolescence (i.e., more support from, less negative interaction with and less dominance from their best friend) than both overcontrollers and undercontrollers. Through the mean levels of friendship quality throughout adolescence, resilients indirectly experienced higher romantic relationship quality during young adulthood than both overcontrollers and undercontrollers. Thus, results provide support for a developmental model in which adolescent friendship quality is a mechanism linking personality types with young adulthood romantic relationship quality.

    Purpose The purpose of this paper is to develop a systematic approach to predict service quality dimension's influence on service quality using a novel analysis based on data envelopment and SERVQUAL. Design/methodology/approach To assess hospital service quality in Tehran, expectation and perception of those who received the services were evaluated using SERVQUAL. The hospital service quality dimensions were found by exploratory factor analysis (EFA). To compare customer expectation and perception, perceived service quality index (PSQI) was measured using a new method based on common weights. A novel sensitivity approach was used to test the service quality factor's impact on the PSQI. Findings A new service quality dimension named "trust in services" was found using EFA, which is not an original SERVQUAL factor. The approach was applied to assess the hospital's service quality. Since the PSQI value was 0.76 it showed that improvements are needed to meet customer expectations. The results showed the factor order that affect PSQI. "Trust in services" has the strongest influence on PSQI followed by "tangibles," "assurance," "empathy," and "responsiveness," respectively. Practical implications This work gives managers insight into service quality by following a systematic method; i.e., measuring perceived service quality from the customer viewpoint and service factors' impact on customer perception. Originality/value The procedure helps managers to select the required service quality dimensions which need improvement and predict their effects on customer perception.

    The scope of visual attention is known to affect conscious object perception, with recent studies showing that a global attentional scope boosts holistic face processing, relative to a local scope. Here we show that attentional scope settings can also modulate the availability of information for conscious visual awareness. In an initial experiment, we show that adopting a global attentional scope accelerates conscious detection of initially invisible faces, presented under continuous flash suppression (CFS). Furthermore, face detection time was not modulated by attentional scope in a nonrivalrous control condition, which emulated the experience of CFS without inducing binocular rivalry. In a follow-up experiment, we report an exact replication of the original effect, as well as data suggesting that this effect is specific to upright faces, and is abolished when using both inverted faces and images of houses in an otherwise identical task. Thus, attentional scope settings can modulate the availability of information to conscious awareness, fundamentally altering the contents of our subjective visual experience.

    A novel Quality Indicator (QI) and Water Quality Index (WQI) were constructed in the present study for the evaluation of the water quality of a Hydroelectric Plant reservoir in the Amazon area, Brazil, taking into account the specific characteristics of the Amazon area. Factor analyses were applied in order to select the relevant parameters to be included in the construction of both indices. Quality curves for each selected parameter were then created and the constructed QI and WQI were then applied to investigate the water quality at the reservoir. The hydrological cycle was shown by the indices to directly affect reservoir water quality, and the WQI was further useful in identifying anthropogenic impacts in the area, since water sampling stations suffering different anthropogenic impacts were categorized differently, with poorer water quality, than stations near the dam and the environmental preservation area, which suffer significantly less anthropogenic impacts, and were categorized as presenting better water quality. The constructed indices are thus helpful in investigating environmental conditions in areas that show well-defined hydrological cycles, in addition to being valuable tools in the detection of anthropogenic impacts. The statistical techniques applied in the construction of these indices may also be used to construct other indices in different geographical areas, taking into account the specificities for each area.

    The popularity of cosmetic surgery has seen a rapid increase recently, with the trend mirrored in dentistry. The Department of Health expressed concerns about the potential for biological and psychosocial harm of these cosmetic procedures. Furthermore, the dental public health implications (DPH) of the growing uptake of cosmetic dental procedures have not been explored. Conduct a scoping review to explore the DPH implications of cosmetic dentistry and identify gaps for future research. A fivestage scoping review was conducted of studies identified using the search terms cosmetic AND dentistry. Data from the studies meeting the inclusion criteria were extracted, collated and summarised into themes. Fifty-seven papers met the inclusion criteria (11 cross-sectional studies, 10 literature reviews and 36 opinion pieces). The DPH implications were summarised into five emergent themes: dento-legal and ethical, marketing, psychosocial, biological and workforce. These themes revealed patients' increased expectations, expanding commercialisation of the profession, psychological risks to vulnerable patients, the iatrogenic consequences of invasive cosmetic dental procedures and workforce implications of the current trends. The scoping review found that existing literature on cosmetic dentistry is predominately anecdotal - professional opinions and discussions. Despite this, our findings demonstrated workforce training and governance implications due to increased demand for cosmetic dentistry. Further empirical research is needed to understand the DPH implications of the increasing demand and uptake of cosmetic dental procedures to guide evidence-based policy to safeguard patients and improve the quality of dental services.

    Learning disability (LD) is a serious and lifelong condition characterised by the impairment of cognitive and adaptive skills. Some cases of LD with unidentified causes may be linked to genetic factors. Next-generation sequencing (NGS) techniques are new approaches to genetic testing that are expected to increase diagnostic yield. This scoping study focused on the diagnosis of LD in children and the objectives were to describe current pathways that involve the use of genetic testing; collect stakeholder views on the changes in service provision that would need to be put in place before NGS could be used in clinical practice; describe the new systems and safeguards that would need to be put in place before NGS could be used in clinical practice; and explore the cost-effectiveness of using NGS compared with conventional genetic testing. A research advisory group was established. This group provided ongoing support by e-mail and telephone through the lifetime of the study and also contributed face-to-face through a workshop. A detailed review of published studies and reports was undertaken. In addition, information was collected through 33 semistructured interviews with key stakeholders. NGS techniques consist of targeted gene sequencing, whole-exome sequencing (WES) and whole-genome sequencing (WGS). Targeted gene panels, which are the least complex, are in their infancy in clinical settings. Some interviewees thought that during the next 3-5 years targeted gene panels would be superseded by WES. If NGS technologies were to be fully introduced into clinical practice in the future a number of factors would need to be overcome. The main resource-related issues pertaining to service provision are the need for additional computing capacity, more bioinformaticians, more genetic counsellors and also genetics-related training for the public and a wide range of staff. It is also considered that, as the number of children undergoing genetic testing increases, there will be an

    Usually, trees with similar pH values on their bark develop epiphytes of similar species, the acidity to be a factor for growth. The aim of the study was evaluate the air quality through isotope δ13C in order to define the levels of environmental quality in the city of Queretaro, Mexico. In this work were collected at least 4 epiphytes positioned in trees of the species Prosopis Laevigata at 25 sites of Queretaro City. The samples were analyzed for trace elements with an inductively coupled plasma atomic emission spectroscopy (ICP). The collecting took place during dry period, in May and early rain June 2011 period, and on four sectors to identify the spatial distribution of pollution, using isotopic analysis of concentration of δ 13C. According with the results there are significant differences among the species in each of the sampled areas. The 5 February Avenue presented greater diversity and richness of δ13C, followed by those who were surveyed in the proximity of the UAQ and finally in the middle-east area. An average value of δ13C-17.92%, followed by those surveyed in the vicinity of the UAQ that correspond to sector I and II with an concentration of δ13C-17.55% and δ13C-17.22%, and finally the samples collected in trees scattered in the East-Sector II and IV with a value of δ13C-17.02% and δ13C-15.62%, respectively. Also were observed differences between the dry and wet period. It is likely that these results of δ 13C in moist period reflect the drag of the isotopes due to rain events that could mark a trend in the dilution of this element, however there is a trend in terms of abundance and composition of finding more impact in those species sampled in dry period, in May and early June 2011.

  16. A study on the influence of track discontinuities on the degradation of the geometric quality supported by GPR

    Paixao, Andre; Fontul, Simona; Salcedas, Tânia; Marques, Margarida

    2017-04-01

    It is known that locations in the track denoting sudden structural changes induce dynamic amplifications in the train-track interaction, thus leading to higher impact loads from trains, which in turn promote a faster development of track defects and increase the degradation of components. Consequently, a reduction in the quality of service can be expected at such discontinuities in the track, inducing higher maintenance costs and decreasing the life-cycle of components. To finding actual evidences on how track discontinuities influence the degradation of the geometric quality, a 50-km long railway section is used as case study. The track geometry data obtained with a recording car is firstly characterized according to the European standard series EN 13848. Then, the results of successive surveys are analysed, making use of various tools such as the standard deviation with moving windows of different sizes and calculating degradation rates. The GPR data was also analysed at the locations corresponding to track discontinuities aiming at better identifying situations where sudden changes occur regarding either the structural characteristics or the track behaviour over the years. The results indicate that the geometric quality degrades faster at locations denoting discontinuities in the track, such as changes in track components, approaches to bridges, tunnels, etc. This behaviour suggests that these sites should be monitored more carefully in the scope of asset management activities in order to maximize the life-cycle of the track and its components. This work is a contribution to COST (European COoperation on Science and Technology) Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar".

    Full Text Available Pathology pertains to the study of a disease; from ancient times it has sought to explain the cause of death through postmortem examination. The advancement of science and technology has led to a greater definition of roles and has favored its development through different subspecialties among which we stands out forensic pathology. This discipline has its own characteristics, scope, case series, procedures and terminology. Likewise, although forensic pathology does not differ substantially from clinical pathology, significant differences can be found between the Anglo American approach and the Latin American approach. Beyond semantics of these alleged differences, the article reviews the concepts involved and discusses the scope and requirements needed to qualify experts, in the understanding that globalizing criteria should establish new paradigms and define the specific roles of the specialty.

    Coconut skim milk and insoluble protein are 2 major byproducts in the production of virgin coconut oil. Coconut skim milk was homogenized along with insoluble protein and spray dried to obtain a value-added product, namely, coconut protein powder (CPP). This study deals with the storage study of CPP under different conditions (refrigerated [control], ambient and accelerated). CPP samples were withdrawn periodically at designated intervals of 15 d for accelerated and control, and 30 d for ambient condition. CPP stored at different conditions exhibited marginal moisture uptake (by 0.74 % w/w for control, 0.76 % w/w for ambient, and 1.26 % w/w for accelerated condition) and as a result, had very little effect on the functional properties of the powder. Withdrawn CPP was tested for sensory quality aspects and subjected to instrumental analysis as well. Withdrawn CPP was incorporated as a milk substitute in dessert (Kheer). Quantitative descriptive analysis of the powder and product (Kheer) showed no significant difference in attributes of CPP during the storage period of 2 mo. Electronic nose analysis revealed that CPP samples were not much different with respect to aroma pattern matching, respectively.

    Service quality is perceived as an important factor for developing patient's loyalty. The aim of this study was to determine the hospital service quality from the patients' viewpoints and the relative importance of quality dimensions in predicting the patient's loyalty. A cross-sectional study was conducted in 2010. The study sample was composed of 943 patients selected from eight private general hospitals in Tehran. The survey instrument was a questionnaire included 24 items about the service quality and 3 items about the patient's loyalty. Exploratory factor analysis was employed to extracting the dimensions of service quality. Also, regression analysis was performed to determining the relative importance of the service quality dimensions in predicting the patient's loyalty. The mean score of service quality and patient's loyalty was 3.99 and 4.16 out of 5, respectively. About 29% of the loyalty variance was explained by the service quality dimensions. Four quality dimensions (Costing, Process Quality, Interaction Quality and Environment Quality) were found to be key determinants of the patient's loyalty in the private hospitals of Tehran. The patients' experience in relation to the private hospitals' services has strong impact on the outcome variables like willingness to return to the same hospital and reuse its services or recommend them to others. The relationship between the service quality and patient's loyalty proves the strategic importance of improving the service quality for dragging and retaining patients and expanding the market share.

    Full Text Available The research studied evaluative method of physiological properties of three stages of fresh gingers including immature stage, early mature stage and mature stage to be alternative for quality checking of maturity fresh ginger. The classification models were built based on both destructive method and non-destructive methods. The destructive variables were texture parameters, crude fiber and moisture content and the non-destructive variables were specific gravity, color (L*, a*, b*, gloss and light reflection in range 400-700 nm. The results showed that increasing of ginger harvesting date significantly affected physiological properties. The partial least squares discriminant analysis (PLS-DA was performed to create a classifying model for harvesting date of fresh ginger. The 55.56% and 100% best accuracy of classification into three stages of maturity could be achieved by the destructive model and the non-destructive model, respectively. The best applicable variables in building the non-destructive model were light reflection at 420, 450, 490, 530, 570, 590, 680 nm and the specific gravity.

    In this study, soil samples collected from the sides of two streams with high debris flow potential at Shenmu and Fengchiou village in Nantou County, Taiwan, were used for seepage tank tests in the laboratory. While the tests were being conducted, observations were made to investigate the relationships among displacement of the slope, quality of the seepage water and occurrence of mass movement. The results showed that according to the change rate, displacement could be divided into two stages, namely, the initial failure displacement stage and primary failure displacement stage. While the displacement of the slope was in primary failure displacement stages, the probability of slope failure became much higher. Before general slope failure, electrical conductivity (EC) and sulfate ion (SO4 2-) concentration of the seepage water increased significantly. The time when EC of the seepage water started to increase rapidly was much earlier than that when displacement of the slope started to increase significantly. Therefore, from the hazard mitigation view, there will be a longer time for response if EC of the seepage water was monitored.

    Full Text Available The subject and the research objective presented in this article is establishing of the relationship between quality assurance and implementation of cleaner production in the generic pharmaceutical industry through the comprehensive concept of continuous improvement. This is mostly related to application of Lean and Six Sigma tools and techniques for process improvement and their link to other known concepts used in the industrial environment, especially manufacturing of generic pharmaceutical products from which two representative case studies were selected for comparative analysis, also considering relevant regulatory requirements in the field of quality management, as well as appropriate quality standards. Although the methodology discussed in this conceptual and practice oriented article is strongly related to chemical engineering, the focus is mainly on process industry, i.e. production systems, rather than any specific technological process itself. The scope of this research is an engineering approach to evaluation of the production systems in terms of continuous improvement concepts application, considering both quality aspects and efficiency of such systems.

    2011-11-01

    Full Text Available Abstract Background A supportive patient safety culture is considered to be an essential condition for improving patient safety. Assessing the current safety culture in general practice may be a first step to target improvements. To that end, we studied internal consistency and construct validity of a safety culture questionnaire for general practice (SCOPE which was derived from a comparable questionnaire for hospitals (Dutch-HSOPS. Methods The survey was conducted among caregivers of Dutch general practice as part of an ongoing quality accreditation process using a 46 item questionnaire. We conducted factor analyses and studied validity by calculating correlations between the subscales and testing the hypothesis that respondents' patient safety grade of their practices correlated with their scores on the questionnaire. Results Of 72 practices 294 respondents completed the questionnaire. Eight factors were identified concerning handover and teamwork, support and fellowship, communication openness, feedback and learning from error, intention to report events, adequate procedures and staffing, overall perceptions of patient safety and expectations and actions of managers. Cronbach's alpha of the factors rated between 0.64 and 0.85. The subscales intercorrelated moderately, except for the factor about intention to report events. Respondents who graded patient safety highly scored significantly higher on the questionnaire than those who did not. Conclusions The SCOPE questionnaire seems an appropriate instrument to assess patient safety culture in general practice. The clinimetric properties of the SCOPE are promising, but future research should confirm the factor structure and construct of the SCOPE and delineate its responsiveness to changes in safety culture over time.

    2017-01-01

    Introduction Multimorbidity becomes increasingly prevalent with ageing. Polypharmacy is often associated with multimorbidity because patients accrue medications to treat each individual disease; however, there is uncertainty around the generalisability of disease-specific guidelines. Namely, the extrapolation of results from studies conducted in younger patients to older adults with multimorbidity. The main objective of this scoping review is to explore our current knowledge of the outcomes that older adults with multimorbidity experience from taking prescribed medications. Methods and analysis A scoping review will be conducted to explore what is known about the outcomes experienced by older adults with multimorbidity who are taking guideline-recommended medications and to identify areas for future research. In addition to searching the grey literature, the following databases will be searched from 1990 onward: MEDLINE, EMBASE, PsycINFO and the Cochrane Library. Experimental, quasi-experimental and non-experimental studies consisting of patients ≥65 years old who have two or more comorbid conditions (explicitly grouped together for the purpose of analysis) and who are being prescribed a guideline-recommended prescription medication for a chronic condition will be considered for inclusion in our scoping review. We will describe patient (eg, mortality, morbidity, quality of life) and health system (eg, number of emergency department visits or hospitalisations, cost to third-party payer) outcomes associated with the prescription of medications for older adults who have two or more chronic comorbid conditions. Two reviewers will complete all screening and data abstraction independently. Data will be synthesised with descriptive statistics. Ethics and dissemination Ethics approval is not required because this is a scoping review of published literature. Results will be disseminated through conference presentations and publication in a peer-reviewed journal. PMID

  20. High-quality weather data for grid integration studies

    2016-12-01

    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. In this talk we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets will be presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The Solar Integration National Dataset (SIND) is available as time synchronized with the WIND Toolkit, and will allow for combined wind-solar grid integration studies. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. Grid integration studies are also carried out in various countries, which aim at increasing their wind and solar penetration through combined wind and solar integration data sets. We will present a multi-year effort to directly support India's 24x7 energy access goal through a suite of activities aimed at enabling large-scale deployment of clean energy and energy efficiency. Another current effort is the North-American-Renewable-Integration-Study, with the aim of providing

    Deployment of customer-sited photovoltaics (PV) in the United States has expanded rapidly in recent years, driven in part by public policies premised on a range of societal benefits that PV may provide. With the success of these efforts, heated debates have surfaced in a number of U.S. states about the impacts of customer-sited PV on utility shareholders and ratepayers, and such debates will likely become only more pronounced and widespread as solar costs continue to decline and deployment accelerates. To inform these discussions, we performed a scoping analysis to quantify the financial impacts of customer-sited PV on utility shareholders and ratepayers and to assess the potential efficacy of various options for mitigating those impacts.

    Full Text Available Background and Aims: Awake flexible fibre-optic bronchoscope (FFS is the standard method of intubation in difficult airway in oral cancer patients. We decided to evaluate GlideScope® video laryngoscope (GL for intubation as compared to the standard FFS for nasal intubation in such patients. Methods: After the ethical committee approval, we included 54 oropharyngeal cancer patients divided randomly into two equal groups: Group G and Group F. After pre-medication and pre-oxygenation, awake nasal intubation was performed using GL in Group G and FFS in Group F. In both groups, we compared intubation time in seconds (mean ± standard deviation (primary outcome, success rate of the first intubation attempt, percentage of Cormack and Lehane glottic score and incidence of complications. We assumed that GL could be a suitable alternative for the standard FFS in nasal intubation of patients with oropharyngeal cancer. Success rate of the first attempt and Cormack and Lehane glottic score were compared using Chi-square test. Results: Intubation time in seconds was significantly shorter in Group G (70.85 ± 8.88 S than in Group F (90.26 ± 9.41 S with (P < 0.001. The success rate of the first attempt intubation was slightly higher in Group G (81.5% than Group F (78.8%. Cormack and Lehane glottic Score I and II showed insignificant difference between both Group G (92.6% and Group F (96.3%. We detected three cases of sore throat in each group. Conclusion: GlideScope® could be a suitable alternative to FFS in nasal intubation of oropharyngeal cancer patients.

    To provide a method to calculate delay cost and examine the relationship between quality and total cost. The total cost including capacity, supply and delay cost for running an interventional radiology suite was calculated. The capacity cost, consisting of labour, lease and overhead costs, was derived based on expenses per unit time. The supply cost was calculated according to actual procedural material use. The delay cost and marginal delay cost derived from queueing models was calculated based on waiting times of inpatients for their procedures. Quality improvement increased patient safety and maintained the outcome. The average daily delay costs were reduced from 1275 € to 294 €, and marginal delay costs from approximately 2000 € to 500 €, respectively. The one-time annual cost saved from the transfer of surgical to radiological procedures was approximately 130,500 €. The yearly delay cost saved was approximately 150,000 €. With increased revenue of 10,000 € in project phase 2, the yearly total cost saved was approximately 290,000 €. Optimal daily capacity of 4.2 procedures was determined. An approach for calculating delay cost toward optimal capacity allocation was presented. An overall quality improvement was achieved at reduced costs. • Improving quality in terms of safety, outcome, efficiency and timeliness reduces cost. • Mismatch of demand and capacity is detrimental to quality and cost. • Full system utilization with random demand results in long waiting periods and increased cost.

    Full Text Available In this paper, we present an empirical study to find the relationship between discretionary accruals quality as well as innate accruals quality and portion of non-executive board of directors, concentration of ownership ratio and board size in Tehran Stock Exchange. The survey selects 118 qualified stocks from this exchange and using a random technique chooses 42 firms. The study implements two linear regression techniques to estimate the first part of the information and then using structural equation modeling examines six hypotheses. Based on the results of this survey we can conclude that an increase on non-executive members positively influences on discretionary accruals quality and negatively influences innate accruals quality. Concentration of ownership ratio positively influences on discretionary accruals quality and negatively impacts on innate accruals quality. Finally, size of board of directors negatively impacts discretionary accruals quality and positively influences on innate accruals quality.

    Childhood obesity rates are steadily rising. Sustainable Childhood Obesity Prevention Through Community Engagement (SCOPE) is a community-based participatory action research (PAR) program aimed at preventing childhood obesity. This study aimed to describe community perspectives on, and elicit feedback about, SCOPE's first phase of implementation in two pilot cities in British Columbia, Canada. A case study was implemented using interviews and questionnaires to obtain feedback about SCOPE from two groups: SCOPE coordinators and stakeholders (i.e., individuals and organizations that were a member of the community and engaged with SCOPE coordinators). Participants were recruited via email and (or) by telephone. Coordinators completed a telephone interview. Stakeholders completed a questionnaire and (or) a telephone interview. Thematic analysis was conducted. Participants included 2 coordinators and 15 stakeholders. Participants similarly interpreted SCOPE as a program focused on raising awareness about childhood obesity prevention, while engaging multiple community sectors. Overall, participants valued the program's role in facilitating networking and partnership development, providing evidence-based resources, technical expertise, and contributing funding. Participants felt that SCOPE is sustainable. However, participants felt that barriers to achieving healthy weights among children included those related to the built environment, and social, behavioral, and economic obstacles. Perspectives on factors that facilitated and acted as barriers to SCOPE's first phase of implementation were obtained from the SCOPE communities and may be used to enhance the sustainability of SCOPE and its applicability to other BC communities.

    Full Text Available Participatory GIS (PGIS has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product.

    Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

Portuguese and Lithuanians consistently gave a significantly higher average importance to all the cues and quality dimensions considered, for all products, than their Danish...... information and price were the most important for Danes. The cues and dimensions Portuguese found relevant were fairly different and more category-dependent. Cues like store type for bread, brand for breakfast cereals, pasta and vodka, country-of-origin for vodka, and price for cookies, pasta and vodka were......Cereal foods' production and use show substantial heterogeneity across Europe. For a category central in most EU diets, cereal foods' quality perception is, nevertheless, surprisingly understudied. With this in mind, 357 Danish, Lithuanian and Portuguese citizens were inquired about the importance...

    The purpose of this study is to describe the volume, topics, and methodological nature of the existing research literature on research data management in academic institutions. We conducted a scoping review by searching forty literature databases encompassing a broad range of disciplines from inception to April 2016. We included all study types and data extracted on study design, discipline, data collection tools, and phase of the research data lifecycle. We included 301 articles plus 10 companion reports after screening 13,002 titles and abstracts and 654 full-text articles. Most articles (85%) were published from 2010 onwards and conducted within the sciences (86%). More than three-quarters of the articles (78%) reported methods that included interviews, cross-sectional, or case studies. Most articles (68%) included the Giving Access to Data phase of the UK Data Archive Research Data Lifecycle that examines activities such as sharing data. When studies were grouped into five dominant groupings (Stakeholder, Data, Library, Tool/Device, and Publication), data quality emerged as an integral element. Most studies relied on self-reports (interviews, surveys) or accounts from an observer (case studies) and we found few studies that collected empirical evidence on activities amongst data producers, particularly those examining the impact of research data management interventions. As well, fewer studies examined research data management at the early phases of research projects. The quality of all research outputs needs attention, from the application of best practices in research data management studies, to data producers depositing data in repositories for long-term use.

    HTTP adaptive streaming is being increasingly deployed by network content providers, such as Netflix and YouTube. By dividing video content into data chunks encoded at different bitrates, a client is able to request the appropriate bitrate for the segment to be played next based on the estimated network conditions. However, this can introduce a number of impairments, including compression artifacts and rebuffering events, which can severely impact an end-user's quality of experience (QoE). We have recently created a new video quality database, which simulates a typical video streaming application, using long video sequences and interesting Netflix content. Going beyond previous efforts, the new database contains highly diverse and contemporary content, and it includes the subjective opinions of a sizable number of human subjects regarding the effects on QoE of both rebuffering and compression distortions. We observed that rebuffering is always obvious and unpleasant to subjects, while bitrate changes may be less obvious due to content-related dependencies. Transient bitrate drops were preferable over rebuffering only on low complexity video content, while consistently low bitrates were poorly tolerated. We evaluated different objective video quality assessment algorithms on our database and found that objective video quality models are unreliable for QoE prediction on videos suffering from both rebuffering events and bitrate changes. This implies the need for more general QoE models that take into account objective quality models, rebuffering-aware information, and memory. The publicly available video content as well as metadata for all of the videos in the new database can be found at http://live.ece.utexas.edu/research/LIVE_NFLXStudy/nflx_index.html.

    To develop an entry-to-practice quality and safety competency profile for radiation oncology residency. A comprehensive list of potential quality and safety competency items was generated from public and professional resources and interprofessional focus groups. Redundant or out-of-scope items were eliminated through investigator consensus. Remaining items were subjected to an international 2-round modified Delphi process involving experts in radiation oncology, radiation therapy, and medical physics. During Round 1, each item was scored independently on a 9-point Likert scale indicating appropriateness for inclusion in the competency profile. Items indistinctly ranked for inclusion or exclusion were re-evaluated through web conference discussion and reranked in Round 2. An initial 1211 items were compiled from 32 international sources and distilled to 105 unique potential quality and safety competency items. Fifteen of the 50 invited experts participated in round 1: 10 radiation oncologists, 4 radiation therapists, and 1 medical physicist from 13 centers in 5 countries. Round 1 rankings resulted in 80 items included, 1 item excluded, and 24 items indeterminate. Two areas emerged more prominently within the latter group: change management and human factors. Web conference with 5 participants resulted in 9 of these 24 items edited for content or clarity. In Round 2, 12 participants rescored all indeterminate items resulting in 10 items ranked for inclusion. The final 90 enabling competency items were organized into thematic groups consisting of 18 key competencies under headings adapted from Deming's System of Profound Knowledge. This quality and safety competency profile may inform minimum training standards for radiation oncology residency programs. Copyright © 2017 Elsevier Inc. All rights reserved.

    Theory of Inventive Problem Solving (TRIZ) is a creative encouraging problem solving method. TRIZ is prepared by Altshuller for product design. Altshuller prepared contradiction matrix and suggestion to solve contradictions usually occur in product design. This paper try to combine TRIZ with quality tools such as Pareto and Fault Tree Analysis (FTA) to solve contradiction in quality improvement problem, neither than product design problem. Pareto used to identify defect priority, FTA used to analysis and identify root cause of defect. When there is contradiction in solving defect causes, TRIZ used to find creative problem solving. As a case study, PT ’X’, a plastic molding manufacturing industry was taken. PT ‘X’ using traditional press machine to produce plastic thread cone. There are 5 defect types that might occur in plastic thread cone production, incomplete form, dirty, mottle, excessive form, rugged. Research about quality improvement effort using DMAIC at PT ‘X’ have been done by Fory Candra. From this research, defect types, priority, root cause from FTA, recommendation from FMEA. In this research, from FTA reviewed, contradictions found among causes troublesome quality improvement efforts. TRIZ used to solve the contradictions and quality improvement effort can be made effectively.

  1. Quality Management in Project Management Consulting. A Case Study in an International Consulting Company

    Directory of Open Access Journals (Sweden)

    Eduard-Gabriel Ceptureanu

    2017-02-01

    Full Text Available The present paper addresses quality management from the specific perspective of project management consulting service providers, in the framework of large infrastructure projects. Because of their supposed superiority in knowledge and experience, project management consultants have an ultimate responsibility for the proper implementing of the project. Therefore, quality management in consulting organizations should focus on critical success factors. As there is no consensus yet regarding the most important aspects of the consulting activity on which depend the achievement of the project aims, there is scope for further investigating this subject. Here, the case of a project management consulting organization involved in large infrastructure projects in Romania, Bulgaria, Moldova, Ukraine and Serbia is analyzed. Data collected through a questionnaire-based survey among international consultants and support personnel suggest that factors related to leadership style and communication skills are more closely tied to the success of the project than more technical aspects. The results constitute an empirical evidence of main success factors for specialized consulting services in project management and can be useful in improving business and project performance and achieving business excellence.

    This report provides the criticality safety information needed for obtaining certification of the shipment of mixed-oxide (MOX) fuel using the MO-1 [USA/9069/B()F] shipping package. Specifically, this report addresses the shipment of non-weapons-grade MOX fuel as certified under Certificate of Compliance 9069, Revision 10. The report further addresses the shipment of weapons-grade MOX fuel using a possible Westinghouse fuel design. Criticality safety analysis information is provided to demonstrate that the requirements of 10 CFR S 71.55 and 71.59 are satisfied for the MO-1 package. Using NUREG/CR-5661 as a guide, a transport index (TI) for criticality control is determined for the shipment of non-weapons-grade MOX fuel as specified in Certificate of Compliance 9069, Revision 10. A TI for criticality control is also determined for the shipment of weapons-grade MOX fuel. Since the possible weapons-grade fuel design is preliminary in nature, this report is considered to be a scoping evaluation and is not intended as a substitute for the final criticality safety analysis of the MO-1 shipping package. However, the criticality safety evaluation information that is presented in this report does demonstrate the feasibility of obtaining certification for the transport of weapons-grade MOX lead test fuel using the MO-1 shipping package.

Since its first publication in January 2006, the system (previously named MaGe for Magnifying Genomes) has been continuously extended both in terms of data content and analysis tools. The last update of MicroScope was published in 2009 in the Database journal. Today, the resource contains data for >1600 microbial genomes, of which ∼300 are manually curated and maintained by biologists (1200 personal accounts today). Expert annotations are continuously gathered in the MicroScope database (∼50 000 a year), contributing to the improvement of the quality of microbial genomes annotations. Improved data browsing and searching tools have been added, original tools useful in the context of expert annotation have been developed and integrated and the website has been significantly redesigned to be more user-friendly. Furthermore, in the context of the European project Microme (Framework Program 7 Collaborative Project), MicroScope is becoming a resource providing for the curation and analysis of both genomic and metabolic data. An increasing number of projects are related to the study of environmental bacterial (meta)genomes that are able to metabolize a large variety of chemical compounds that may be of high industrial interest.

    Full Text Available Pancreatic resection is a standard procedure for the treatment of periampullary tumors. Morbidity and mortality are high, and quality standards are scarce in our setting. International classifications of complications (Clavien-Dindo and those specific for pancreatectomies (ISGPS allow adequate case comparisons. The goals of our work are to describe the morbidity and mortality of 480 pancreatectomies using the international classifications ISGPS and Clavien-Dindo to help establish a quality standard in our setting and to compare the results of CPD with reconstruction by pancreaticogastrostomy (1,55 versus 177 pancreaticojejunostomy. We report 480 resections including 337 duodenopancreatectomies, 116 distal pancreatectomies, 11 total pancreatectomies, 10 central pancreatectomies, and 6 enucleations. Results for duodenopancreatectomy include: 62 % morbidity (Clavien ≥ III 25.9 %, 12.3 % reinterventions, and 3.3 % overall mortality. For reconstruction by pancreaticojejunostomy: 71.2 % morbidity (Clavien ≥ III 34.4 %, 17.5 % reinterventions, and 3.3 % mortality. For reconstruction by pancreaticogastrostomy: 51 % morbidity (Clavien ≥ III 15.4%, 6.4 % reinterventions, and 3.2 % mortality. Differences are significant except for mortality. We conclude that our series meets quality criteria as compared to other groups. Reconstruction with pancreaticogastrostomy significantly reduces complication number and severity, as well as pancreatic fistula and reintervention rates.

    To provide a method to calculate delay cost and examine the relationship between quality and total cost. The total cost including capacity, supply and delay cost for running an interventional radiology suite was calculated. The capacity cost, consisting of labour, lease and overhead costs, was derived based on expenses per unit time. The supply cost was calculated according to actual procedural material use. The delay cost and marginal delay cost derived from queueing models was calculated based on waiting times of inpatients for their procedures. Quality improvement increased patient safety and maintained the outcome. The average daily delay costs were reduced from 1275 EUR to 294 EUR, and marginal delay costs from approximately 2000 EUR to 500 EUR, respectively. The one-time annual cost saved from the transfer of surgical to radiological procedures was approximately 130,500 EUR. The yearly delay cost saved was approximately 150,000 EUR. With increased revenue of 10,000 EUR in project phase 2, the yearly total cost saved was approximately 290,000 EUR. Optimal daily capacity of 4.2 procedures was determined. An approach for calculating delay cost toward optimal capacity allocation was presented. An overall quality improvement was achieved at reduced costs. (orig.)

    China is undergoing rapid urbanization because of unprecedented economic growth. As a result, many cities suffer from air pollution. Two-thirds of China's cities have not attained the ambient air quality standards applicable to urban residential areas (Grade II). Particulate matter (PM), rather than sulfur dioxide (SO2), is the major pollutant reflecting the shift from coal burning to mixed source pollution. In 2002, 63.2 and 22.4% of the monitored cities have PM and SO2 concentrations exceeding the Grade II standard, respectively. Nitrogen oxides (NOx) concentration kept a relatively stable level near the Grade II standard in the last decade and had an increasing potential in recent years because of the rapid motorization. In general, the air pollutants emission did not increase as quickly as the economic growth and energy consumption, and air quality in Chinese cities has improved to some extent. Beijing, a typical representative of rapidly developing cities, is an example to illustrate the possible options for urban air pollution control. Beijing's case provides hope that the challenges associated with improving air quality can be met during a period of explosive development and motorization.

    Ideally, quality is designed into software, just as quality is designed into hardware. However, when dealing with legacy systems, demonstrating that the software meets required quality standards may be difficult to achieve. As the need to demonstrate the quality of existing software was recognized at Los Alamos National Laboratory (LANL), an effort was initiated to uncover and demonstrate that legacy software met the required quality standards. This effort led to the development of a reverse engineering approach referred to as software archaeology. This paper documents the software archaeology approaches used at LANL to document legacy software systems. A case study for the Robotic Integrated Packaging System (RIPS) software is included.

    Perceived service quality is the most important predictor of patient satisfaction. The purpose of this study was to investigate the impact of the service quality on the overall satisfaction of patients in private hospitals of Tehran, Iran. This cross-sectional study was conducted in the year 2010. The study's sample consisted of 969 patients who were recruited from eight private general hospitals in Tehran, Iran using consecutive sampling. A questionnaire was used for data collection; contacting 21 items (17 items about service quality and 4 items about overall satisfaction) and its validity and reliability were confirmed. Data analysis was performed using t-test, ANOVA and multivariate regression. this study found a strong relationship between service quality and patient satisfaction. About 45% of the variance in overall satisfaction was explained by four dimensions of perceived service quality. The cost of services, the quality of the process and the quality of interaction had the greatest effects on the overall satisfaction of patients, but not found a significant effect on the quality of the physical environment on patient satisfaction. Constructs related to costs, delivery of service and interpersonal aspect of care had the most positive impact on overall satisfaction of patients. Managers and owners of private hospitals should set reasonable prices compared to the quality of service. In terms of process quality, waiting time for visits, admissions, and surgeries must be declined and services provided at the fastest possible time. It should be emphasized to strengthen of interpersonal aspects of care and communication skills of care providers.

    To describe the evolution of methods and share lessons learned from conducting multi-state studies with Medicaid Medical Directors (MMD) using state administrative data. There was a great need for these studies, but also much to be learned about conducting network-based research and ensuring comparability of results. This was a network-level case study. The findings were drawn from the experience developing and executing network analyses with the MMDs, as well as from participant feedback on lessons learned. For the latter, nine interviews with MMD project leads, state data analysts, and outside researchers involved with the projects were conducted. Interviews were transcribed, coded and analyzed using NVivo 10.0 analytic software. MMD study methodology involved many steps: developing research questions, defining data specifications, organizing an aggregated data collection spreadsheet form, assuring quality through review, and analyzing and reporting state data at the national level. State analysts extracted the data from their state Medicaid administrative (claims) databases (and sometimes other datasets). Analysis at the national level aggregated state data overall, by demographics and other sub groups, and displayed descriptive statistics and cross-tabs. Projects in the MMD multi-state network address high-priority clinical issues in Medicaid and impact quality of care through sharing of data and policies among states. Further, these studies contribute not only to high-quality, cost-effective health care for Medicaid beneficiaries, but also add to our knowledge of network-based research. Continuation of these studies requires funding for a permanent research infrastructure nationally, as well as at the state-level to strengthen capacity.

    Objective The main objective of this study was to determine the relationship between the characteristics of nurses' work environments in hospitals in the Spanish National Health System (SNHS) with nurse reported quality of care, and how care was provided by using different shifts schemes. The study also examined the relationship between job satisfaction, burnout, sleep quality and daytime drowsiness of nurses and shift work. Methods This was a multicentre, observational, descriptive, cross-sectional study, centred on a self-administered questionnaire. The study was conducted in seven SNHS hospitals of different sizes. We recruited 635 registered nurses who worked on day, night and rotational shifts on surgical, medical and critical care units. Their average age was 41.1 years, their average work experience was 16.4 years and 90% worked full time. A descriptive and bivariate analysis was carried out to study the relationship between work environment, quality and safety care, and sleep quality of nurses working different shift patterns. Results 65.4% (410) of nurses worked on a rotating shift. The Practice Environment Scale of the Nursing Work Index classification ranked 20% (95) as favourable, showing differences in nurse manager ability, leadership and support between shifts (p=0.003). 46.6% (286) were sure that patients could manage their self-care after discharge, but there were differences between shifts (p=0.035). 33.1% (201) agreed with information being lost in the shift change, showing differences between shifts (p=0.002). The Pittsburgh Sleep Quality Index reflected an average of 6.8 (SD 3.39), with differences between shifts (p=0.017). Conclusions Nursing requires shift work, and the results showed that the rotating shift was the most common. Rotating shift nurses reported worse perception in organisational and work environmental factors. Rotating and night shift nurses were less confident about patients' competence of self-care after discharge. The

    Reactive scope predicts that all animals have an adaptive ability to respond to stressors in their environment, termed reactive homeostasis, and that only when an animal's response to stressful stimuli exceeds a certain threshold (homeostatic overload) will stress have pathological effects. While this framework has successfully helped interpret effects of stressors on wildlife, no study has designed an experiment to directly test this framework. This study was designed to expose house sparrows (Passer domesticus) to treatments that would result in varying ranges of reactive homeostasis during chronic stress, which based on the reactive scope model should cause birds with the lowest reactive homeostasis range to exhibit signs of pathology during a subsequent challenge. To modulate the reactive homeostasis range, we altered allostatic load of birds by exposing them to chronic stress while either elevating, blocking, or not manipulating corticosterone. After concluding chronic stress treatments, birds were exposed to the subsequent challenge of a superficial wound. Individuals treated with corticosterone during chronic stress (high allostatic load) experienced the most pathology, including both weight loss and slower wound healing. Unmanipulated birds (medium allostatic load) also experienced weight loss but had normal healing rates, while birds with blocked corticosterone (low allostatic load) had minimal weight loss and normal healing rates. Our results indicate that increased allostatic load reduces the reactive homeostasis range, thereby causing individuals to cross the homeostatic overload threshold sooner, and thus support the reactive scope framework.

    The goal of mammography is to provide contrast between a lesion that is possible residing within the breast and normal surrounding tissue. Quality control is essential for maintaining the contrast imaging performance of a mammography system and incorporate tests that are relevant in that they are predictive of future degradation of contrast imaging performance. These tests will also be done at frequency that is high enough to intercept most drifts in quality imaging or performance before they become diagnostically significant. The quality control study has as objective to describe the results of the assessment of quality imaging elements (film optical density, contrast (density difference), uniformity, resolution and noise) of 62 mammography departments without quality control program and comparison these results with a mammography reference department with a quality control program. When comparing the results they allow seeing the clinical utility of to have a quality control program to reduce the errors of mammography interpretation. (Author)

    Successful quality improvement (QI) requires a supportive context. The goal was to determine whether a structured curriculum could help QI teams improve the context supporting their QI work. An exploratory field study was conducted of 43 teams participating in a neonatal intensive care unit QI collaborative. Using a curriculum based on the Model for Understanding Success in Quality, teams identified gaps in their context and tested interventions to modify context. Surveys and self-reflective journals were analyzed to understand how teams developed changes to modify context. More than half (55%) targeted contextual improvements within the microsystem, focusing on motivation and culture. "Information sharing" interventions to communicate information about the project as a strategy to engage more staff were the most common interventions tested. Further study is needed to determine if efforts to modify context consistently lead to greater outcome improvements.

    The concept of Quality of Life is becoming an increasingly important measure of the impact of psychiatric disorders and is now recognized as useful in the healthcare evaluation of patients with psychiatric disorders. The aim of this review was to document and analyze the research data on quality of life in Nigerian patients with psychiatric disorders. The electronic databases, Medline and Pubmed were searched for published articles on quality of life in Nigerian patients with psychiatric disorders. A total of 6 studies met the inclusion criteria. All the studies employed the generic World Health Organization Quality of Life Scale - Brief version, which is the only quality of life instrument whose psychometric properties have been evaluated among Nigerian patients with psychiatric disorders. Some of the studies revealed that quality of life was significantly associated with socio demographic factors such marital and employment status and social support. Poor quality of life was reported to be associated with illness related factors such as co morbid medical problems, presence of anxiety and depressive symptoms and non adherence to medications. All the studies with the exception of two were conducted in centers located in South-western Nigeria. Quality of life in Nigerian patients suffering from psychiatric disorders is under-researched. There is need for more studies to prospectively investigate quality of life and associated factors among Nigerian patients with psychiatric disorders.

  9. Water Temperature, Invertebrate Drift, and the Scope for Growth for Juvenile Spring Chinook Salmon.

    Lovtang, J. C.; Li, H. W.

    2005-05-01

    We present a bioenergetic assessment of habitat quality based on the concept of the scope for growth for juvenile Chinook salmon. Growth of juvenile salmonids during the freshwater phase of their life history depends on a balance between two main factors: energy intake and metabolic costs. The metabolic demands of temperature and the availability of food play integral roles in determining the scope for growth of juvenile salmonids in stream systems. We investigated differences in size of juvenile spring Chinook salmon in relation to water temperature and invertebrate drift density in six unique study reaches in the Metolius River Basin, a tributary of the Deschutes River in Central Oregon. This project was initiated to determine the relative quality and potential productivity of habitat in the Metolius Basin prior to the reintroduction of spring Chinook salmon, which were extirpated from the middle Deschutes basin in the early 1970's due to the construction of a hydroelectric dam. Variations in the growth of juvenile Chinook salmon can be described using a multiple regression model of water temperature and invertebrate drift density. We also discuss the relationships between our bioenergetic model, variations of the ideal free distribution model, and physiological growth models.

  10. Cost Analysis of Poor Quality Using a Software Simulation

    2017-02-01

    Full Text Available The issues of quality, cost of poor quality and factors affecting quality are crucial to maintaining a competitiveness regarding to business activities. Use of software applications and computer simulation enables more effective quality management. Simulation tools offer incorporating the variability of more variables in experiments and evaluating their common impact on the final output. The article presents a case study focused on the possibility of using computer simulation Monte Carlo in the field of quality management. Two approaches for determining the cost of poor quality are introduced here. One from retrospective scope of view, where the cost of poor quality and production process are calculated based on historical data. The second approach uses the probabilistic characteristics of the input variables by means of simulation, and reflects as a perspective view of the costs of poor quality. Simulation output in the form of a tornado and sensitivity charts complement the risk analysis.

    The quality of water in water distribution system may vary with both location and time. Water quality models were used to predict spatial and temporal variation of water quality throughout the water system. Before analyzing the variations of water quality, it is necessary to determine the hydrodynamics in water distribution system. Analytical methods for the flow path from water sources to the observed point and water age of every observed node are proposed. This paper makes a further study on water supply route of multi-sources water supply network system. These studies have been applied to an actual water distribution system.

    An Atmospheric Modelling System has been set up at International Centre for Integrated Mountain Development (ICIMOD) for the assessment of Air Quality across the Himalaya mountain ranges. The Weather Research and Forecasting (WRF) model version 3.5 has been implemented over the regional domain, stretching across 4995 x 4455 km2 centred at Ichhyakamana , the ICIMOD newly setting-up mountain-peak station (1860 m) in central Nepal, and covering terrains from sea-level to the Everest (8848 m). Simulation is carried out for the winter time period, i.e. December 2012 to February 2013, when there was an intensive field campaign SusKat, where at least 7 super stations were collecting meteorology and chemical parameters on various sites. The very complex terrain requires a high horizontal resolution (1 × 1 km2), which is achieved by nesting the domain of interest, e.g. Kathmandu Valley, into 3 coarser ones (27, 9, 3 km resolution). Model validation is performed against the field data as well as satellite data, and the challenge of capturing the necessary atmospheric processes is discussed, before moving forward with the fully coupled chemistry module (WRF-Chem), having local and regional emission databases as input. The effort aims at finding a better understanding of the atmospheric processes and air quality impact on the mountain population, as well as the impact of the long-range transport, particularly of Black Carbon aerosol deposition, to the radiative budget over the Himalayan glaciers. The higher rate of snowcap melting, and shrinkage of permafrost as noticed by glaciologists is a concern. Better prediction will supply crucial information to form the proper mitigation and adaptation strategies for saving people lives across the Himalayas in the changing climate.

    The use of two-dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low-quality and high-quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low-quality or high-quality images, and then completed a comprehension test using either 2D images or three-dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high-quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high-quality vs. low-quality for hand anatomy P = 0.018; high-quality vs. low-quality for eye anatomy P = 0.247). Also, the benefit of high-quality images on hand anatomy learning was restricted to performance on short-answer (SA) questions immediately after learning (high-quality vs. low-quality on SA questions P = 0.018), but did not apply to performance on multiple-choice (MC) questions (high-quality vs. low-quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

    Hospital governance is broadening its orientation from cost and production controls towards 'improving performance on clinical outcomes'. Given this new focus one might assume that doctors are drawn into hospital management across OECD countries. Hospital performance in terms of patient health, quality of care and efficiency outcomes is supposed to benefit from their involvement. However, international comparative evidence supporting this idea is limited. Just a few studies indicate that there may be a positive relationship between medical doctors being part of hospital boards, and overall hospital performance. More importantly, the assumed relationship between these so-called doctor managers and hospital performance has remained a 'black-box' thus far. However, there is an increasing literature on the implementation of quality management systems in hospitals and their relation with improved performance. It seems therefore fair to assume that the relation between the involvement of doctors in hospital management and improved hospital performance is partly mediated via quality management systems. The threefold aim of this paper is to 1) perform a quick scan of the current situation with regard to doctor managers in hospital management in 19 OECD countries, 2) explore the phenomenon of doctor managers in depth in 7 OECD countries, and 3) investigate whether doctor involvement in hospital management is associated with more advanced implementation of quality management systems. This study draws both on a quick scan amongst country coordinators in OECD's Health Care Quality Indicator program, and on the DUQuE project which focused on the implementation of quality management systems in European hospitals. This paper reports two main findings. First, medical doctors fulfil a broad scope of managerial roles at departmental and hospital level but only partly accompanied by formal decision making responsibilities. Second, doctor managers having more formal decision making

    2017-05-16

    The Sustainable Development Goals (SDGs) emphasises the increasing equitable coverage of quality health care and provision of integrated services as means of reducing maternal mortality. Despite so much effort being placed on improved access to maternity health care, studies show that women with disabilities are being systemically excluded from the mainstream maternal health services. The proposed scoping review aims to map literature on the barriers and facilitators of access to maternal services for women with disabilities. The search strategy for this scoping review study will involve electronic databases including Pubmed, MEDLINE via EBSCOhost, CINAHL Plus with full text via EBSCOhost, Africa-Wide Info via EBSCOhost, JSTOR and Proquest Health and Medical Complete. Articles will also be searched through the "Cited by" search as well as citations included in the reference lists of included articles. A two-stage mapping strategy would be conducted. Stage 1 would be to screen studies through examining their titles. Furthermore, we will screen abstracts of the identified studies descriptively and by focus and method as stipulated by the inclusion and exclusion criteria. In stage 2, we will extract data from the included studies. A parallel screening and data extraction will be undertaken by two reviewers. We will access the quality of the included studies using the mixed methods appraisal tool (MMAT). We will use NVIVO version 10 to extract the relevant outcomes and thematic analysis of the studies. We anticipate to find relevant studies reporting evidence on the barriers and facilitators of access to maternal health services in Sub-Saharan Africa. The evidence obtained from the included studies when summarised will help guide future research. The study findings will be disseminated electronically and in print. In addition, it will be presented at conferences related to sexual reproductive health, maternal health care and reproductive health.

  19. Geoinformatics Approach for Groundwater Prospects and Quality Studies - A Review

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Water is a prime requirement for all the living and non-living processes. On the earth, 71% is water but the availability of useable fresh water for drinking and other purposes is about 2.8%. Out of this 2.8 % fresh water, the share of groundwater is only 0.6% that makes it more pertinent to conservation, preservation, and management. The urbanization, industrialization, and intensive agricultural practices have put further pressure on the available fresh water. The modern techniques like space technology, GIS and GPS have great utility in mapping, monitoring, planning and management of water resources. The temporal satellite data in different spectral bands and on different spatial resolutions make the remote sensing satellite data highly useful for mapping and monitoring of an area. The geographical information system (GIS has the capability to store, retrieve, edit and represent the data in informative way. The global positioning system (GPS gives the real time geo-coordinates, path and altitude of desired object or terrain. Thus, the geoinformatics have huge potential for solving the problems of groundwater availability and quality, and there is a need to harness the potential of these techniques for societal benefits to provide water everyone.
