    Our objective was to assess the reported reasons for episiotomy performance in Israel and to review the relevant professional literature. Using anonymous questionnaires, a survey was conducted among obstetricians and midwives in four northern Israel hospitals, and the accoucheurs were asked to score their agreement with 13 proposed indications for episiotomy. Overall, 84 doctors and 32 midwives completed the questionnaires. 86.1% of the responders reported performing episiotomy in all or most cases of shoulder dystocia, and more than half reported performing it in most cases of vacuum deliveries, fetal macrosomia and advanced perineal tear in previous delivery. Subjective assessment of perineal characteristics constituted a justified reason for episiotomy for 15.8-43.9% of the accoucheurs. In conclusion, there is a wide variation in reported reasons for episiotomy between the obstetricians, and many of these indications are not congruent with international practice guidelines. Uniform protocols and educational programmes are needed to guide episiotomy practice.

    The environmental performance review mission took place in April 2002, at a time when the Government was preparing new constitutions for the federation and the republics that would, interalia, change their respective responsibilities. The review covers Serbia and Montenegro but not Kosovo and Metohija. Part I covers environmental policy and management, Part II management of pollution and of natural resources (air, water, waste and mineral resources management, biodiversity conservation and nature protection), and Part III economic and sectoral integration. Recommendations are made to remedy environmental damage caused by coal mining in Serbia and Montenegro. Yugoslavia has not ratified the Kyoto Protocol. It has begun work on preparing its first national communication to the UN Framework Convention on Climate Change.

    The second OECD Review of Spain's environmental performance reviews Spain's progress in the context of OECD environmental strategy for the first decade of the 21st century in relation to its own policy objectives. It praises a number of achievements such as in commitments to climate change policies and developments of cogeneration and renewable energy sources. Although emissions of sulphur dioxide from the energy sector have fallen since 1990 they are still high when measured per capita and per unit of GDP. The OECD recommends further control of emissions of SOx, NOx, VOCs and NH{sub 3}. Subsidies such as compulsory purchase of domestic coal by electricity producers are set to increase. The report recommends the phasing out of environmental subsidies (which has begun) and making use of economic instruments to encourage efficient resource management and reduction of pollutants. Greenhouse gas emissions increased by 38% between 1990 and 2002 and the outlook for the next few years is pessimistic. 39 figs., 31 tabs.

  11. Emerging trends in peer review - a survey

    Directory of Open Access Journals (Sweden)

    Richard eWalker

    2015-05-01

    Full Text Available Classical peer review has been subject to intense criticism for slowing down the publication process, bias against specific categories of paper and author, unreliability, inability to detect errors and fraud, unethical practices, and the lack of recognition for unpaid reviewers. This paper surveys innovative forms of peer review that attempt to address these issues. Based on an initial literature review, we construct a sample of 81 channels of scientific communication covering all forms of review identified by the survey and analyze the review mechanisms used by each channel. We identify two major trends: the rapidly expanding role of pre-print servers (e.g. ArXiv that dispense with traditional peer review altogether and the growth of non-selective review, focusing on papers’ scientific quality rather than their perceived importance and novelty. Other potentially important developments include forms of open review, which remove reviewer anonymity and interactive review, as well as new mechanisms for post-publication review and out-of-channel reader commentary, especially critical commentary targeting high profile papers. One of the strongest findings of the survey is the persistence of major differences between the peer review processes used by different disciplines. None of these differences is likely to disappear in the foreseeable future. The most likely scenario for the coming years is thus continued diversification, in which different review mechanisms serve different author and reader needs. Relatively little is known about the impact of these innovations on the problems they address. These are important questions for future quantitative research.

    OECD's comprehensive 2004 report on Canada's environmental policies and programmes systematically examines policy related to air, water, and nature/biodiversity as well as the interface between environmental policy and economic policy, social policy, and specific sectors. It finds that while Canada has made satisfactory progress since 1985, there are still significant challenges, and the report makes specific recommendations for more use of economic instruments and use of the polluter and user pays principles, rationalising water governance, strengthening nature protection, reducing energy intensity, implementing climate change policies, reviewing environmentally related taxes, and implementing marine and aid commitments. Coal provides about 20% of Canada's electric power. Most direct subsidisation of the fossil fuel supply industries (upstream oil, gas and coal) has been reduced. The report recommends subsidies to the mining industry for exploration should also be phased out. Recent measurements indicate emissions of mercury are increasing, mainly due to long-range transboundary air pollution from coal-burning plants. 42 figs., 24 tabs.

    The probability of detecting residual contamination in the field using portable radiological survey instruments depends not only on the sensitivity of the instrumentation used in scanning, but also on the surveyor`s performance. This report provides a basis for taking human performance into account in determining the minimum level of activity detectable by scanning. A theoretical framework was developed (based on signal detection theory) which allows influences on surveyors to be anticipated and understood, and supports a quantitative assessment of performance. The performance of surveyors under controlled yet realistic field conditions was examined to gain insight into the task and to develop means of quantifying performance. Then, their performance was assessed under laboratory conditions to quantify more precisely their ability to make the required discriminations. The information was used to characterize surveyors` performance in the scanning task and to provide a basis for predicting levels of radioactivity that are likely to be detectable under various conditions by surveyors using portable survey instruments.

    The review surveys the environmental conditions and environmental progress of Poland. It found that although most environmental targets were met Poland still faces challenges in complying with EU environmental laws. Topics covered are: environmental management; air, water and waste management; nature and biodiversity; economy and environment; sectoral integration: transport; and international co-operation. Top issues for conformity include pollution prevention, waste water treatment, waste management, biodiversity and landscape conservation, and climate protection. The review outlines 46 recommendations for the country to take in order to improve its environmental situation. Task areas include progressing toward meeting international environmental commitments and integrating environmental considerations in to economic policies through means such as improved rice signals, subsidy removal, and fiscal reforms.

  4. Updating systematic reviews: an international survey.

    Directory of Open Access Journals (Sweden)

    Chantelle Garritty

    Full Text Available BACKGROUND: Systematic reviews (SRs should be up to date to maintain their importance in informing healthcare policy and practice. However, little guidance is available about when and how to update SRs. Moreover, the updating policies and practices of organizations that commission or produce SRs are unclear. METHODOLOGY/PRINCIPAL FINDINGS: The objective was to describe the updating practices and policies of agencies that sponsor or conduct SRs. An Internet-based survey was administered to a purposive non-random sample of 195 healthcare organizations within the international SR community. Survey results were analyzed using descriptive statistics. The completed response rate was 58% (n = 114 from across 26 countries with 70% (75/107 of participants identified as producers of SRs. Among responders, 79% (84/107 characterized the importance of updating as high or very-high and 57% (60/106 of organizations reported to have a formal policy for updating. However, only 29% (35/106 of organizations made reference to a written policy document. Several groups (62/105; 59% reported updating practices as irregular, and over half (53/103 of organizational respondents estimated that more than 50% of their respective SRs were likely out of date. Authors of the original SR (42/106; 40% were most often deemed responsible for ensuring SRs were current. Barriers to updating included resource constraints, reviewer motivation, lack of academic credit, and limited publishing formats. Most respondents (70/100; 70% indicated that they supported centralization of updating efforts across institutions or agencies. Furthermore, 84% (83/99 of respondents indicated they favoured the development of a central registry of SRs, analogous to efforts within the clinical trials community. CONCLUSIONS/SIGNIFICANCE: Most organizations that sponsor and/or carry out SRs consider updating important. Despite this recognition, updating practices are not regular, and many organizations lack

    Studies have demonstrated the value of the follow-up skeletal survey in identifying additional fractures, clarifying indeterminate findings, and improving dating of skeletal injuries in victims of physical abuse. To determine whether a more limited follow-up survey could yield the same radiologic data as a full follow-up survey. The study cohort comprised 101 children who had follow-up surveys that met our inclusion criteria. Consensus readings of both original and follow-up surveys were performed by two pediatric radiologists. These results were compared to determine additional findings from the follow-up surveys. Limited skeletal survey protocols were evaluated to determine whether they would detect the same fractures seen with a complete osseous survey. In the 101 children 244 fractures were identified on the initial osseous survey. Follow-up surveys demonstrated new information in 38 children (37.6%). A 15-view limited follow-up survey identified all additional information seen on the complete follow-up survey. Our data demonstrate that a 15-view limited follow-up skeletal survey could be performed without missing clinically significant new fractures and still allow proper identification of confirmed fractures or normal findings. A limited survey would decrease radiation dose in children. (orig.)

    Rural panel surveys are the most appropriate source of data for studying the unprecedented rapid migration and urbanization currently taking place in China and other developing countries. This paper provides a selective review, focusing on the panel survey methodologies of several studies, which are organized based on our proposed four key elements of panel surveys: representativeness, retrospect-prospect, multilevel tracking, and temporality. To maximize heterogeneity in urbanization and development over the last three decades, we select rural panel surveys from five Asian countries: India, Indonesia, Nepal, Thailand, and China. We analyze the strengths and weaknesses of the selected panel surveys to provide directions for designing future rural panel surveys in China and elsewhere in the developing world.

  20. Ethics Review of Survey Research: A Mandatory Requirement for Publication?

    Science.gov (United States)

    Whicher, Danielle; Wu, Albert W

    2015-12-01

    National regulations governing human subjects research differ with regard to whether they require survey research to be overseen by institutional ethics boards or committees. In cases where ethical review has been waived, or was provided by an individual or group other than an institutional ethics board, journals may question the appropriateness of the waiver or alternative review when making determinations about whether to accept the manuscript for publication. The purpose of this article is to provide guidance for journals to consider when making determinations about the necessity of ethical review for survey research projects. We review the functions of ethics oversight and consider the importance of those functions within the context of survey research. In survey research, no intervention is delivered to research participants. As a result, there is no risk of physical harm to individuals who participate. However, there can be a risk of informational or psychological harms. In situations where there is greater than minimal risk of informational or psychological harms, the survey research should have received institutional ethics oversight. Additionally, survey research projects that enroll vulnerable individuals with diminished autonomy should receive institutional ethics oversight. We hope that this article leads to further guidance on this subject by authoritative group such as the International Committee of Medical Journal Editors.

    Several rounds of national health surveys have generated a vast amount of data in India since 1992. We describe and compare the key health information gathered, assess the availability of health data in the public domain, and review publications resulting from the National Family Health Survey (NFHS), the District Level Household Survey (DLHS) and the Annual Health Survey (AHS). We highlight issues that need attention to improve the usefulness of the surveys in monitoring changing trends in India's disease burden: (i) inadequate coverage of noncommunicable diseases, injuries and some major communicable diseases; (ii) modest comparability between surveys on the key themes of child and maternal mortality and immunization to understand trends over time; (iii) short time intervals between the most recent survey rounds; and (iv) delays in making individual-level data available for analysis in the public domain. We identified 337 publications using NFHS data, in contrast only 48 and three publications were using data from the DLHS and AHS respectively. As national surveys are resource-intensive, it would be prudent to maximize their benefits. We suggest that India plan for a single major national health survey at five-year intervals in consultation with key stakeholders. This could cover additional major causes of the disease burden and their risk factors, as well as causes of death and adult mortality rate estimation. If done in a standardized manner, such a survey would provide useable and timely data to inform health interventions and facilitate assessment of their impact on population health.

    Food consumption surveys are performed in many countries. Comparison of results from those surveys across nations is difficult because of differences in methodological approaches. While consensus about the preferred methodology associated with national food consumption surveys is increasing, no inventory of methodological aspects across continents is available. The aims of the present review are (1) to develop a framework of key methodological elements related to national food consumption surveys, (2) to create an inventory of these properties of surveys performed in the continents North-America, South-America, Asia and Australasia, and (3) to discuss and compare these methodological properties cross-continentally. A literature search was performed using a fixed set of search terms in different databases. The inventory was completed with all accessible information from all retrieved publications and corresponding authors were requested to provide additional information where missing. Surveys from ten individual countries, originating from four continents are listed in the inventory. The results are presented according to six major aspects of food consumption surveys. The most common dietary intake assessment method used in food consumption surveys worldwide is the 24-HDR (24 h dietary recall), occasionally administered repeatedly, mostly using interview software. Only three countries have incorporated their national food consumption surveys into continuous national health and nutrition examination surveys.

The inventory was completed with all accessible information from all retrieved publications and corresponding authors were requested to provide additional information where missing. Surveys from ten individual countries, originating from four continents are listed in the inventory. The results are presented according to six major aspects of food consumption surveys. The most common dietary intake assessment method used in food consumption surveys worldwide is the 24-HDR (24 h dietary recall, occasionally administered repeatedly, mostly using interview software. Only three countries have incorporated their national food consumption surveys into continuous national health and nutrition examination surveys.

    Full Text Available Performance evaluation of an economic entity requires approaching several criteria, such as industry and economic entity type, managerial and entrepreneurial strategy, competitive environment, human and material resources available, using a system of appropriate performance indicators for this purpose.The exigencies of communication occurred on the growing number of phenomena that marked the global economy in recent decades (internationalization and relocation of business crises and turmoil in financial markets, demand performance measurement to be made in a comprehensive way by financial and non-financial criteria. Indicators are measures of performance used by management to measure, report and improve performance of the economic entity. The relationship between indicators and management is ensured by the existence of performance measurement systems. Studies to date indicate that economic entities using balanced performance measurement systems as a key management tool registered superior performance compared to entities not using such systems. This study attempts to address the issue of performance evaluation by presenting opinions of different authors concerning the process of performance measurement and to present, after revising the literature, the evolution of the performance evaluation systems. We tried to do this literature review because sustainable development and, therefore, globalization require new standards of performance that exceeds the economic field, both for domestic companies as well as international ones. So, these standards should be integrated into corporate strategy development to ensure sustainability of activities undertaken by harmonizing the economic, social and environmental objectives. To assess the performance of economic entities it is required that performance evaluation to be done with a balanced multidimensional system, including both financial ratios and non-financial indicators in order to reduce the limits of

  14. A Review About SAR Technique for Shallow Water Bathymetry Surveys

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Synthetic Aperture Radar (SAR) has become one of the important tools for shallow water bathymetry surveys. This has significant economic efficiency compared with the traditional bathymetry surveys. Numerical models have been developed to simulate shallow water bathymetry SAR images. Inversion of these models makes it possible to assess the water depths from SAR images. In this paper, these numerical models of SAR technique are reviewed, and examples are illustrated including in the coastal areas of China. Some issues about SAR technique available and the research orientation in future are also discussed.

    Farley, ORL, Abbiss, CR, and Sheppard, JM. Performance Analysis of Surfing: A Review. J Strength Cond Res 31(1): 260-271, 2017-Despite the increased professionalism and substantial growth of surfing worldwide, there is limited information available to practitioners and coaches in terms of key performance analytics that are common in other field-based sports. Indeed, research analyzing surfing performance is limited to a few studies examining male surfers' heart rates, surfing activities through time-motion analysis (TMA) using video recordings and Global Positioning Satellite (GPS) data during competition and recreational surfing. These studies have indicated that specific activities undertaken during surfing are unique with a variety of activities (i.e., paddling, resting, wave riding, breath holding, and recovery of surfboard in the surf). Furthermore, environmental and wave conditions also seem to influence the physical demands of competition surfing. It is due to these demands that surfers are required to have a high cardiorespiratory fitness, high muscular endurance, and considerable strength and anaerobic power, particular within the upper torso. By exploring various methods of performance analysis used within other sports, it is possible to improve our understanding of surfing demands. In so doing this will assist in the development of protocols and strategies to assess physiological characteristics of surfers, monitor athlete performance, improve training prescription, and identify talent. Therefore, this review explores the current literature to provide insights into methodological protocols, delimitations of research into athlete analysis and an overview of surfing dynamics. Specifically, this review will describe and review the use of TMA, GPS, and other technologies (i.e., HR) that are used in external and internal load monitoring as they pertain to surfing.

  16. A Survey of Quality Prediction of Product Reviews

    H.Almagrabi

    2015-11-01

    Full Text Available With the help of Web-2.0, the Internet offers a vast amount of reviews on many topics and in different domains. This has led to an explosive growth of product reviews and customer feedback, which presents the problem of how to handle the abundant volume of data. It is an expensive and time-consuming task to analyze this huge content of opinions. Therefore, the need for automated sentiment analysis systems is vital. However, these systems encounter many challenges; assessing the content quality of the posted opinions is an important area of study that is related to sentiment analysis. Currently, review helpfulness is assessed manually; however the task of automatically assessing it has gained more attention in recent years. This paper provides a survey of approaches to the challenge of identifying the content quality of product reviews.

  18. Innovation and organisational performance: A systematic review

    Directory of Open Access Journals (Sweden)

    Tebogo Gilbert Sethibe

    2015-08-01

    Full Text Available This paper is an attempt to consolidate the published scientific knowledge about the impact of leadership styles on the relationship between innovation and organisational performance. Concepts, statements and conceptual frameworks were used as structure to analyse the body of scientific knowledge. After consulting 31 major research databases using the systematic literature review methodology, only seven journals articles that examined the link between leadership, innovation and organisational performance were identified. The synthesis of the journal articles revealed (a that consensus exists among researchers as far as the relevant concepts are concerned; (b that most agree on the definition of leadership and innovation but that a uniform understanding of what constitutes organisational performance is lacking; and (c that conceptual models are too simplistic and do not consider mediator variables or multiple financial criteria measures. The findings further reveal that innovation is significantly and positively related to superior organisational performance, and that, although transformational leadership style is significantly and positively related to innovation, transactional leadership style is more appropriate when the aim is to instil a culture of innovation. Transformational leadership style, by contrast, is mostly associated with organisational performance. In addition, the findings further reveal that none of the studies investigate the mediating effect of the nature of innovation (incremental and radical on the relationship between leadership and organisational performance, and that none of the studies use the objective measures of financial performance such as ROA, ROE, price/earnings (P/E and Tobin’s Q calculated from annual financial reports.

  3. Are physicians willing to ration health care? Conflicting findings in a systematic review of survey research☆

    Science.gov (United States)

    Strech, Daniel; Persad, Govind; Marckmann, Georg; Danis, Marion

    2013-01-01

    Background Several quantitative surveys have been conducted internationally to gather empirical information about physicians’ general attitudes towards health care rationing. Are physicians ready to accept and implement rationing, or are they rather reluctant? Do they prefer implicit bedside rationing that allows the physician–patient relationship broad leeway in individual decisions? Or do physicians prefer strategies that apply explicit criteria and rules? Objectives To analyse the range of survey findings on rationing. To discuss differences in response patterns. To provide recommendations for the enhancement of transparency and systematic conduct in reviewing survey literature. Methods A systematic search was performed for all English and non-English language references using CINAHL, EMBASE, and MEDLINE. Three blinded experts independently evaluated title and abstract of each reference. Survey items were extracted that match with: (i) willingness to ration health care or (ii) preferences for different rationing strategies. Results 16 studies were eventually included in the systematic review. Percentages of respondents willing to accept rationing ranged from 94% to 9%. Conclusions The conflicting findings among studies illustrate important ambivalence in physicians that has several implications for health policy. Moreover, this review highlights the importance to interpret survey findings in context of the results of all previous relevant studies. PMID:19070396

  4. PERFORMANCE MEASUREMENT IN HIGHER EDUCATION: LITERATURE REVIEW

    Directory of Open Access Journals (Sweden)

    Andreea Ioana COSTE

    2015-06-01

    Full Text Available Significant actions have been taken to define the concept of performance measurement. Many researchers have been discussing and developing this topic. Also, not only in the recent literature are many studies regarding the topic, but now are more than ever. At international level, International Public Sector Accounting Standard Board took the decision to develop a framework for reporting service performance measurement that focuses on meeting the needs of intended users. In this way, around the world, will be a uniform understanding and applicability for performance measurement. This paper analyzes the concept of performance measurement. The main objective of the paper is to do a review of the definitions received by the concept in time, thus a qualitative approach will be used. Furthermore, this paper tries to examine the changes which occurred in public universities due to the budget constraints. Performance measurement plays a central role because, in this way, universities prove their accountability and to show the way in which they have value the money.

    The Telescope Performance Monitor (TPM) installed at the Sloan Digital Sky Survey (SDSS) located at Apache Point Observatory provides access to real-time and archived engineering data. The modularity present in the underlying Experimental Physics and Industrial Control System (EPICS) toolkit allows the observers and operations staff to develop their own approaches to data access and analysis. These techniques are summarized and the use of the TPM to solve critical project issues including analysis and correction of thermal management problems are presented.

    Over a 5-year observing period, the Sloan Digital Sky Survey (SDSS) will acquire data to construct a digital 5-color photometric map of the Northern Galactic sky to about 23rd magnitude, and a correspondingly large and homogeneous spectroscopic survey. The SDSS is in a unique class of projects, in that all aspects of the SDSS infrastructure, from the telescopes and instruments, to software and operations staffing, were designed and assembled specifically to conduct this Survey. To ensure success, observing operations are run in production mode and performance metrics are used to measure progress over time. The methodology of preparing the performance baseline plan, and an assessment of Survey progress after two full years of operation, are reviewed and some lessons learned discussed. In particular, the SDSS has benefited greatly by asking peers in the field to participate in external reviews that periodically assess performance and offer independent, fresh views of potential areas of concerns. Additionally, difficulties caused by the absence of an experienced systems-engineering staff during the final phase of construction and commissioning are reviewed. The challenges of building a production machine out of complex and state-of-the-art sub-systems cannot be overstated. In the case of the SDSS, insufficient systems engineering led to problems meeting initial image quality requirements, primarily because of problems with the thermal performance of the telescope and its environment. A concerted campaign to deal with these issues was successful, but that success came rather later than we would have liked. The improvements made to address the situation, and the resulting increase in operational performance, are discussed.

  7. Landslide databases review in the Geological Surveys of Europe

    Science.gov (United States)

    Herrera, Gerardo

    2017-04-01

    Landslides are one of the most widespread geohazards in Europe, producing significant social and economic damages. Rapid population growth in urban areas throughout many countries in Europe and extreme climatic scenarios can considerably increase landslide risk in the near future. However, many European countries do not include landslide risk into their legislation. Countries lack official methodological assessment guidelines and knowledge about landslide impacts. Although regional and national landslide databases exist in most countries, they are often not integrated because they are owed by different institutions. Hence, a European Landslides Directive, that provides a common legal framework for dealing with landslides, is necessary. With this long-term goal in mind, we present a review of the landslide databases from the Geological Surveys of Europe focusing on their interoperability. The same landslide classification was used for the 849,543 landslide records from the Geological Surveys, from which 36% are slides, 10 % falls, 20% flows, 11% complex slides and 24% remain either unclassified or correspond to another typology. A landslide density map was produced from the available records of the Geological Surveys of 17 countries showing the variable distribution of landslides. There are 0.2 million km2 of landslide prone areas. The comparison of this map with the European landslide susceptibility map ELSUS v1 was successful for 73% of the predictions, and permitted identification of 25% of susceptible areas where landslide records are not available from the Geological Surveys. Taking these results into account the completeness of these landslide databases was evaluated, revealing different landslide hazard management approaches between surveys and countries.

    To determine how students who are referred to a competency committee for concern over performance, and ultimately judged not to require remediation, perform during internship. Uniformed Services University of the Health Sciences' students who graduated between 2007 and 2011 were included in this study. We compared the performance during internship of three groups: students who were referred to the internal medicine competency committee for review who met passing criterion, students who were reviewed by the internal medicine competency committee who were determined not to have passed the clerkship and were prescribed remediation, and students who were never reviewed by this competency committee. Program Director survey results and United States Medical Licensing Examination (USMLE) Step 3 examination results were used as the outcomes of interest. The overall survey response rate for this 5-year cohort was 81% (689/853). 102 students were referred to this competency committee for review. 63/102 students were reviewed by this competency committee, given passing grades in the internal medicine clerkship, and were not required to do additional remediation. 39/102 students were given less than passing grades by this competency committee and required to perform additional clinical work in the department of medicine to remediate their performance. 751 students were never presented to this competency committee. Compared to students who were never presented for review, the group of reviewed students who did not require remediation was 5.6 times more likely to receive low internship survey ratings in the realm of professionalism, 8.6 times more likely to receive low ratings in the domain of medical expertise, and had a higher rate of USMLE Step 3 failure (9.4% vs. 2.8%). When comparing the reviewed group to students who were reviewed and also required remediation, the only significant difference between groups regarding professionalism ratings with 50% of the group requiring

    The aim of this study is to analyze biomedical publications on health surveys (HS) in the Catalan territory from documents published in various bibliographic databases to 2010. Analysis of 1,287 HS documents on 3 bibliographic sources of information relating to Catalonia, between 1991 and 2010. Scientific papers on HS in the Catalan territory have been 196. We studied the variables related to the topic of the article published, the magazine publication of the survey, the characteristics of sampling and the sample size, geographical area and timing of the survey. The articles reviewed represent 15.23% of all original documents. Half of them have been published in Spanish journals, stressing Gaceta Sanitaria and Medicina Clínica and the most studied issues are health and lifestyles. A 40.8% clearly explicit the characteristics of the sample, the size of them range between 49 and 23,126 individuals. It is suggested that HS in Catalonia are useful for generating knowledge about health, lifestyle and health resource utilization of the population, and its disclosure among health experts and the public.

    Directory of Open Access Journals (Sweden)

    Mazin Alshamrani

    2016-05-01

    Full Text Available The implementation of the Session Initiation Protocol (SIP-based Voice over Internet Protocol (VoIP and multimedia over MANET is still a challenging issue. Many routing factors affect the performance of SIP signaling and the voice Quality of Service (QoS. Node mobility in MANET causes dynamic changes to route calculations, topology, hop numbers, and the connectivity status between the correspondent nodes. SIP-based VoIP depends on the caller’s registration, call initiation, and call termination processes. Therefore, the SIP signaling performance has an important role for the overall QoS of SIP-based VoIP applications for both IPv4 and IPv6 MANET. Different methods have been proposed to evaluate and benchmark the performance of the SIP signaling system. However, the efficiency of these methods vary and depend on the identified performance metrics and the implementation platforms. This survey examines the implementation of the SIP signaling system for VoIP applications over MANET and highlights the available performance enhancement methods.

  1. A review of electrochromic window performance factors

    Energy Technology Data Exchange (ETDEWEB)

    Selkowitz, S.E.; Rubin, M.; Lee, E.S.; Sullivan, R.; Finlayson, E.; Hopkins, D.

    1994-04-01

    The performance factors which will influence the market acceptance of electrochromic windows are reviewed. A set of data representing the optical properties of existing and foreseeable electrochromic window devices was generated. The issue of reflective versus absorbing electrochromics was explored. This data was used in the DOE 2.1 building energy model to calculate the expected energy savings compared to conventional glazings. The effects of several different control strategies were tested. Significant energy and peak electric demand benefits were obtained for some electrochromic types. Use of predictive control algorithms to optimize cooling control may result in greater energy savings. Initial economic results considering annual savings, cooling equipment cost savings, and electrochromic window costs are presented. Calculations of thermal and visual comfort show additional benefits from electrochromics but more work is needed to quantify their importance. The design freedom and aesthetic possibilities of these dynamic glazings should provide additional market benefits, but their impact is difficult to assess at this time. Ultimately, a full assessment of the market viability of electrochromics must consider the impacts of all of these issues.

    Full Text Available Transmission Control Protocol (TCP is a connection-oriented transport service that ensures the reliability of message delivery. It verifies that messages and data were received. TCP provides reliable, ordered delivery of a stream of bytes from a program on one computer to another program on another computer. TCP provides a communication service at an intermediate level between an application programs. TCP is the protocol used by major Internet applications such as the World Wide Web, email, remote administration and file transfer. TCP is a reliable transport protocol that is well tuned to perform well in traditional networks. However, several experiments and analysis have shown that this protocol is not suitable for bulk data transfer in high bandwidth, large round trip time networks because of its slow start and conservative congestion control mechanism. In this paper we discussed a survey of Performance Based Transmission Control Protocol in Mobile Ad-hoc Network environment. The performance based techniques are categorized based upon different approaches like throughput, end-to-end delay, congestion control etc. We also analysis the major improvement in recent methods for performance based TCP in MANET.

    Full Text Available Abstract Background Although systematic reviews of health care interventions are an invaluable tool for health care providers and researchers, many potential authors never publish reviews. This study attempts to determine why some people with interest in performing systematic reviews do not subsequently publish a review; and what steps could possibly increase review completion. Methods Cross-sectional survey by email and facsimile of the 179 participants in Australasian Cochrane Centre training events between 1998 and 2000. Results Ninety-two participants responded to the survey (51 percent. Response rate of deliverable surveys was 82 percent (92/112. The remainder of the participants had invalid or no contact information on file. More than 75 percent of respondents felt that the current workshops met their needs for training. The most critical barriers to completion of a Cochrane review were: lack of time (80 percent, lack of financial support (36 percent, methodological problems (23 percent and problems with group dynamics (10 percent. Conclusions Strategies to protect reviewer time and increase the efficiency of the review process may increase the numbers of trained reviewers completing a systematic review.

  4. SKA Weak Lensing II: Simulated Performance and Survey Design Considerations

    Bonaldi, Anna; Camera, Stefano; Brown, Michael L

    2016-01-01

    We construct a pipeline for simulating weak lensing cosmology surveys with the Square Kilometre Array (SKA), taking as inputs telescope sensitivity curves; correlated source flux, size and redshift distributions; a simple ionospheric model; source redshift and ellipticity measurement errors. We then use this simulation pipeline to optimise a 2-year weak lensing survey performed with the first deployment of the SKA (SKA1). Our assessments are based on the total signal-to-noise of the recovered shear power spectra, a metric that we find to correlate very well with a standard dark energy figure of merit. We first consider the choice of frequency band, trading off increases in number counts at lower frequencies against poorer resolution; our analysis strongly prefers the higher frequency Band 2 (950-1760 MHz) channel of the SKA-MID telescope to the lower frequency Band 1 (350-1050 MHz). Best results would be obtained by allowing the centre of Band 2 to shift towards lower frequency, around 1.1 GHz. We then move o...

    Peer review (PR) of treatment plans has been recognized internationally as a key component of quality care in radiation oncology programs (ROPs). We conducted a survey of Canadian ROPs to describe current PR practices and identify barriers/facilitators to PR optimization. A 42-item e-survey was sent to all Canadian ROPs (n = 44). Survey development was guided by expert consensus, literature review, and existing guidelines. One multidisciplinary response per ROP was requested. Response rate was 100.0% (44/44). All ROPs (100.0%) reported conducting some PR and rated its importance as 7/10 or higher (10 = extremely important). One-half of ROPs (52.3%) peer-reviewed >80% of curative treatment plans. ROPs reported performing PR "always/almost always" pretreatment (38.6%) or before 25% of radiation therapy delivery (52.3%). The majority of ROPs reported recommending major plan changes in ROPs perceive PR as highly important, but substantial variation in the extent, timing, and documentation of PR exists. The understanding of current PR activities, barriers, and facilitators will inform the development of initiatives to optimize PR in radiation oncology.

    Because of insufficient evidence from direct comparison trials, the use of indirect or mixed treatment comparison methods has attracted growing interest recently. We investigated the views and knowledge of Cochrane systematic review authors regarding the use of indirect comparison and related methods in the evaluation of competing healthcare interventions. An online survey was sent to 84 authors of Cochrane systematic review reviews between January and March 2011. The response rate was 57%. Most respondents (87%) had heard of/had some knowledge of indirect comparison, and 23% actually used indirect comparison methods. Some were suspicious of the methods (9%). Most authors (89%) felt they needed more training, especially in assessing the validity of indirect evidence. Almost all felt that the validity of indirect comparison could potentially be influenced by a large number of effect modifiers. Many reviewers (76%) accepted that indirect evidence is needed as it may be the only source of information for relative effectiveness of competing interventions, provided that review authors and readers are conscious of its limitations. Time commitment and resources needed were identified as an important concern for Cochrane reviewers. In summary, there is an acceptance of the increasing demand for indirect comparison and related methods and an urgent need to develop structured guidance and training for its use and interpretation.

  10. A Critical Review of Surveys Emphasizing on Routing in Wireless Sensor Networks—An Anatomization under General Survey Design Framework

    Science.gov (United States)

    2017-01-01

    A large number of routing-related surveys are published so far for Wireless Sensor Networks (WSNs) that exhibit either complete or partial emphasis on routing in WSNs. These surveys classify and discuss the relevant routing protocols published mainly in the fields of classical, energy efficient, secure, hierarchical, geographic, intelligent, Quality of Service (QoS)-based and multipath WSNs. However, to the best of our knowledge, no study is presented so far which may clearly categorize the routing-related survey literature for WSNs.To fill this gap, an effort is made in this paper for presenting an in-depth review of already published routing-related survey literature in WSNs. Our review initially proposes a generalized survey design model and afterwards analyzes the routing-related survey literature in the light of the devised General Survey Design Framework (GSDF). Such an analysis describes the design soundness of the published routing-related surveys. Therefore, our review puts forth an original classification based on the frequency-of-survey-publication and taxonomizes the corresponding routing-related fields into high, medium and low focused areas of survey publication in WSNs. Furthermore, the surveys belonging to each main category are sub-categorized into various sub-classes and briefly discussed according to their design characteristics. On the one hand, this review is useful for beginners who may easily explore the already published routing-related survey literature in WSNs in a single document and investigate it by spending less effort. On the other hand, it is useful for expert researchers who may explore the trends and frequency of writing surveys in different areas of routing in WSNs. The experts may explore those areas of routing which are either neglected or least focused or lack in design soundness as per general survey design framework. In the end, insights and future research directions are outlined and a reasonable conclusion is put forth

    The advancement of various fields of science depends on the actions of individual scientists via the peer review process. The referees' work patterns and stochastic nature of decision making both relate to the particular features of refereeing and to the universal aspects of human behavior. Here, we show that the time a referee takes to write a report on a scientific manuscript depends on the final verdict. The data is compared to a model, where the review takes place in an ongoing competition of completing an important composite task with a large number of concurrent ones - a Deadline -effect. In peer review human decision making and task completion combine both long-range predictability and stochastic variation due to a large degree of ever-changing external "friction".

    Electronic health (eHealth) literacy of consumers is essential in order to improve information and communication technology (ICT) use for health purposes by ordinary citizens. However, performed eHealth literacy is seldom studied. Therefore, the present study assessed perceived and performed eHealth literacy using the recent conceptualization of health literacy skills. The aim of this paper was to examine the association between perceived and performed eHealth literacies. In total, 82 Israeli adults participated in the study, all 50 years and older, with a mean age of 67 (SD 11). Of the participants, 60% (49/82) were women and 72% (59/82) had a post-secondary education. The participants were first surveyed and then tested in a computer simulation of health-related Internet tasks. Performed, perceived (eHealth Literacy Scale, eHEALS), and evaluated eHealth literacy were assessed, and performed eHealth literacy was also recorded and re-evaluated later. Performance was scored for successful completion of tasks, and was also assessed by two researchers for motivation, confidence, and amount of help provided. The skills of accessing, understanding, appraising, applying, and generating new information had decreasing successful completion rates. Generating new information was least correlated with other skills. Perceived and performed eHealth literacies were moderately correlated (r=.34, P=.01) while facets of performance (ie, digital literacy and eHealth literacy) were highly correlated (r=.82, Pliteracy were significantly different: low performers were older and had used the Internet for less time, required more assistance, and were less confident in their conduct than high performers. The moderate association between perceived and performed eHealth literacy indicates that the latter should be assessed separately. In as much, the assessment of performed eHealth literacy in clinical settings should entail the structuring of tasks as well as shortening and automatizing

  17. Review of five successful microbial geochemical surface surveys in Canada

    Munnecke, D.M. [Environmental BioTechnologies Inc., San Carlos, CA (United States)

    1999-11-01

    The development of a new surface geochemical survey technology to detect hydrocarbon microseeps was discussed. Microbial Exploration Technology (MET) was developed by Environmental BioTechnologies Inc., of San Carlos, California. It is used to determine the near surface soil`s metabolic activity towards metabolism of gaseous hydrocarbons. After several years of testing, the technology was commercialized in Canada in 1996. Since then, more than 3 million acres of land in Canada have been surveyed using MET. Surveys are conducted by collecting soil samples in a quarter by quarter mile grid pattern. The samples are then sent to California for analysis. One of the unique characteristics of MET is that it provides a contour map indicating the percent probability of drilling success. This paper presented the following five MET surveys as examples of what types of results can be obtained from the surveys: (1) Flinton Survey (T11 R6 W2), (2) Elcott Survey (T1-2 R1-3 W2), (3) Silverton Survey (T3 R32 W1), (4) Swift Current Block (T13-15 R10-R13 W3), and (5) Border Block (T1-2 R12-14 W3). Each example demonstrates that MET can be very supportive for oil and gas exploration and exploitation activities. It was suggested that running MET surveys before seismic surveys helps in determining where seismic surveys should be conducted to reduce overall exploration costs by 30 to 60 per cent, while improving drilling success. 6 figs.

  20. A review of benthic faunal surveys in San Francisco Bay

    Nichols, Frederic H.

    1973-01-01

    During the past 60 years, considerable effort has been expended in studies of the relations of the biotic community and physicochemical characteristics of San Francisco Bay water. In very recent years these studies have emphasized the relations between the 'state of health' of bottom-living invertebrates (the benthos) and the levels of pollutants in the bay. Benthic organisms, generally sessile, are unable to escape deleterious environmental changes, and they reflect these changes in alterations of normal species composition of assemblages and species abundance. Data that expands understanding of these relations in urbanized areas such as San Francisco Bay are critical. Because of the implications of such data in control of water quality, the U.S. Geological Survey undertook a review of the results and major conclusions of San Francisco Bay benthic surveys. The size and species composition of faunal assemblages are largely controlled by the salinity of the water, the texture of the bottom sediments, and locally by wastes discharged into the bay. Efforts to describe the structure and function of benthic communities of the bay and to quantify the effects of waste discharge on them have been hampered by inconsistent and often faulty sampling methodology and species identification. Studies made show a lack of information on the normal life processes of the organisms concerned. The diversity index (a mathematical expression of the number of kinds of organisms present at a location), commonly used to describe the 'health' of the benthic community, has been employed without regard for the need for standardizing methodology and species identifications or for understanding natural biological processes that affect such mathematical indices. There are few reliable quantitative data on the distribution of benthic organisms in San Francisco Bay with which future assessments of the 'health' of the benthic community might be compared. Methods for study of the benthos must be

    Full Text Available The human aspect in the present context has acquired immense importance. The needbased motivational theories relate need and psychological gratification to motivation and jobsatisfaction; they consider performance as the endresult. However, Lawler and Porter postulatereversely that job performance leads to job satisfaction. The study focuses on testing the degree anddirection of the relationship between Performance and Job Satisfaction with intervening variablessuch as job relations, commitment, role conflict, value system, motivation and organizational climateand with socio-economic variables. The study is conducted on 928 employees drawn from 13 publicsector and 5 private sector organizations using simple random sampling and males as the matchingsample in the State of Andhra Pradesh, India. It isevident from the study that the performance levelof the employees is significantly lesser than theirjob satisfaction level. The analysis leads to state thatall those performing well are satisfied and all those satisfied do not perform well indicating thatperformance leads to job satisfaction, job satisfaction does not lead necessarily to performance andthe relationship is intertwined. This empirical evidence supports the theory of Lawler and Porter andsets direction for future studies at micro level.

    Full Text Available Low back pain (LBP is an increasingly debilitating and costly problem. One of the research focuses in LBP is an attempt to improve patient outcomes. It is believed that the promotion of evidence based practice (EBP should improve patient outcomes and also reduce the cost of care. There seems to be a need to establish how physiotherapists manage LBP and whether management is in accordance with best practice based on published research evidence. The aim of this study was to determine what management strategies physiotherapists employ in the management of LBP by performing a review of the literature and to compare this with recent guidelines Fourteen studies were included for the review.  The treatments most frequently reported as being used for the management of LBP were education/ advice, exercise, spinal mobilisation and electrotherapy. Over a 14 year period there were no major changes in the way physiotherapists manage LBP. Physiotherapist use interventions that are evidence based as well as interventions with little evidence in the management of LBP.

    The economics of dengue is complex and multifaceted. We performed a systematic review of the literature to provide a critical overview of the issues related to dengue economics research and to form a background with which to address the question of cost. Three literature databases were searched [PubMed, Embase and Latin American and Caribbean Health Sciences Literature (LILACS)], covering a period from 1980 to 2013, to identify papers meeting preset inclusion criteria. Studies were reviewed for methodological quality on the basis of a quality checklist developed for this purpose. An expert survey was designed to identify priority areas in dengue economics research and to identify gaps between the methodology and actual practice. Survey responses were combined with the literature review findings to determine stakeholder priorities in dengue economics research. The review identified over 700 papers. Forty-two of these papers met the selection criteria. The studies that were reviewed presented results from 32 dengue-endemic countries, underscoring the importance of dengue as a global public health problem. Cost analyses were the most common, with 21 papers, followed by nine cost-effectiveness analyses and seven cost-of-illness studies, indicating a relatively strong mix of methodologies. Dengue annual overall costs (in 2010 values) ranged from US$13.5 million (in Nicaragua) to $56 million (in Malaysia), showing cost variations across countries. Little consistency exists in the way costs were estimated and dengue interventions evaluated, making generalizations around costs difficult. The current evidence suggests that dengue costs are substantial because of the cost of hospital care and lost earnings. Further research in this area will broaden our understanding of the true economic impact of dengue.

    This study attempts to establish a ranking for species that are routinely released to the environment for a projected nuclear power growth scenario. Unlike comparisons made to existing standards, which are subject to frequent revision, the ranking of releases can be used to form a more logical basis for identifying the areas where further development of control technology could be required. This report describes projections of releases for several fuel cycle scenarios, identifies areas where alternative control technologies may be implemented, and discusses the available alternative control technologies. The release factors were used in a computer code system called ENFORM, which calculates the annual release of any species from any part of the LWR nuclear fuel cycle given a projection of installed nuclear generation capacity. This survey of fuel cycle releases was performed for three reprocessing scenarios (stowaway, reprocessing without recycle of Pu and reprocessing with full recycle of U and Pu) for a 100-year period beginning in 1977. The radioactivity releases were ranked on the basis of a relative ranking factor. The relative ranking factor is based on the 100-year summation of the 50-year population dose commitment from an annual release of radioactive effluents. The nonradioactive releases were ranked on the basis of dilution factor. The twenty highest ranking radioactive releases were identified and each of these was analyzed in terms of the basis for calculating the release and a description of the currently employed control method. Alternative control technology is then discussed, along with the available capital and operating cost figures for alternative control methods.

    Borosilicate glass is to be used for permanent disposal of high-level nuclear waste in a geologic repository. Mechanistic chemical models are used to predict the rate at which radionuclides will be released from the glass under repository conditions. The most successful and useful of these models link reaction path geochemical modeling programs with a glass dissolution rate law that is consistent with transition state theory. These models have been used to simulate several types of short-term laboratory tests of glass dissolution and to predict the long-term performance of the glass in a repository. Although mechanistically based, the current models are limited by a lack of unambiguous experimental support for some of their assumptions. The most severe problem of this type is the lack of an existing validated mechanism that controls long-term glass dissolution rates. Current models can be improved by performing carefully designed experiments and using the experimental results to validate the rate-controlling mechanisms implicit in the models. These models should be supported with long-term experiments to be used for model validation. The mechanistic basis of the models should be explored by using modern molecular simulations such as molecular orbital and molecular dynamics to investigate both the glass structure and its dissolution process.

  16. Sprint performance under heat stress: A review.

    Girard, O; Brocherie, F; Bishop, D J

    2015-06-01

    Training and competition in major track-and-field events, and for many team or racquet sports, often require the completion of maximal sprints in hot (>30 °C) ambient conditions. Enhanced short-term (heat exposure (muscle temperature rise), can be attributed to improved muscle contractility. Under heat stress, elevations in skin/core temperatures are associated with increased cardiovascular and metabolic loads in addition to decreasing voluntary muscle activation; there is also compelling evidence to suggest that large performance decrements occur when repeated-sprint exercise (consisting of brief recovery periods between sprints, usually 39 °C). Here we also discuss strategies (heat acclimatization, precooling, hydration strategies) employed by "sprint" athletes to mitigate the negative influence of higher environmental temperatures.

    2016-09-01

    Full Text Available The concept of supply chain management has been evolving at a rapid pace in economic practice as wellas in scientific research, mainly in the field of logistics and supply chains. It also constitutes a reference point for researchers specializing in accounting, especially in management accounting. As a result, in recent years there has been an increasing number of publications on this research in the world, including in Poland. So far, however, there is a lack of publications that would present comprehensively the aspects of management accounting in the context of supply chain management. Therefore, this article has the following research objective: identification of the degree of development of management accounting, in research and practice, for the purposes of supply chain management. As research methods were used:review of the content of scientific articles and surveys conducted among companies in Poland. The results of survey study and literature review revealed that the most frequently addressed issues in business and in theory include cost management and performance measurement using financial indicators. In the case of other issues addressed in the publications there are discrepancies between theory and business practice. In effect, this means the need to improve the communication and integration of these two dimensions in the context of implementation of management accounting tools and methods for supply chain management support. The results presented in the article could be the basis for further, in-depth research in this area.

    2011-11-01

    Lightweight Autonomous Underwater Vehicles (AUVs) were developed for Naval Special Warfare (NSW) Group 4 search and survey missions from a commercial AUV baseline (Iver 2) through integration of commercial off-the-shelf (COTS) hardware components, and through software development for enhanced on-board Command and Control functions. The development period was 1 year under a project sponsored by the Office of Naval Research TechSolutions Program Office. Hardware integration was completed by the commercial AUV vendor, OceanServer Technology, Inc., and software development was conducted by the Naval Undersea Warfare Center, Naval Oceanographic Office, and U MASS Dartmouth, with support from hardware and software application providers (YSI, Inc., Imagenex Technology Corp., and CARIS). At the conclusion of the integration and development period, an at-sea performance evaluation was scheduled for the Lightweight NSW AUVs with NSWG-4 personnel. The venue for this evaluation was the NATO exercise Recognized Environmental Picture 10A (REP 10A), hosted by Marinha Portuguesa, and coordinated by the Faculdade de Engenharia-Universidade do Porto. REP 10A offered an opportunity to evaluate the performance of the new AUVs and to explore the Concept of Operations (CONOPS) for employing them in military survey operations in shallow coastal waters. Shore- and ship-launched scenarios with launch/recovery by a single operator in a one-to-many coordinated survey, on-scene data product generation and visualization, data push to Reach Back Cells for product integration and enhancement, and survey optimization to streamline survey effort and timelines were included in the CONOPS review. Opportunities to explore employment of hybrid AUV fleets in Combined Force scenarios were also utilized. The Naval Undersea Warfare Center, Marinha Portuguesa, the Faculdade de Engenharia-Universidade do Porto, and OceanServer Technology, Inc., were the primary participants bringing in-water resources to

  11. Pulse-modulation imaging-review and performance analysis.

    Science.gov (United States)

    Chen, D G; Matolin, D; Bermak, A; Posch, C

    2011-02-01

    In time-domain or pulse-modulation (PM) imaging, the incident light intensity is not encoded in amounts of charge, voltage, or current as it is in conventional image sensors. Instead, the image data are represented by the timing of pulses or pulse edges. This method of visual information encoding optimizes the phototransduction individually for each pixel by abstaining from imposing a fixed integration time for the entire array. Exceptionally high dynamic range (DR) and improved signal-to-noise ratio (SNR) are immediate benefits of this approach. In particular, DR is no longer limited by the power-supply rails as in conventional complementary metal-oxide semiconductor (CMOS) complementary metal-oxide semiconductor active pixel sensors, thus providing relative immunity to the supply-voltage scaling of modern CMOS technologies. In addition, PM imaging naturally supports pixel-parallel analog-to-digital conversion, thereby enabling high temporal resolution/frame rates or an asynchronous event-based array readout. The applications of PM imaging in emerging areas, such as sensor network, wireless endoscopy, retinal prosthesis, polarization imaging, and energy harvesting are surveyed to demonstrate the effectiveness of PM imaging in low-power, high-performance machine vision, and biomedical applications of the future. The evolving design innovations made in PM imaging, such as high-speed arbitration circuits and ultra-compact processing elements, are expected to have even wider impacts in disciplines beyond CMOS image sensors. This paper thoroughly reviews and classifies all common PM image sensor architectures. Analytical models and a universal figure of merit - image quality and dynamic range to energy complexity factor are proposed to quantitatively assess different PM imagers across the entire spectrum of PM architectures.

    The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs), conducted with a 60/90 cm Schmidt telescope at Xinglong station of NAOC. This survey repeatedly covers ~ 1000 square degrees of the north sky with a cadence of 3-4 days. With an exposure of 60 s, the survey reaches a limited unfiltered magnitude of about 19.5 mag. This enables us to discover supernovae at their relatively young stages. In this paper, we describe the overall performance of our survey during the first year and present some preliminary results.

    The first half of the review dedicated to survey works on Be stars (Baade, Martayan, and Rivinius, this vol.) put emphasis on what we can learn from surveys about Be stars as a part of an environment, such as Be stars in binaries, Be stars in different metalicities, or Be stars as part of a star forming and then co-evolving group. This second half will rather concentrate on the information that more focused surveys can give on a Be star, understood as an individual object, and in this way attempts to bridge the gap between highly detailed single star studies, and necessarily broad survey and catalog work.

  19. Deception studies manipulating centrally acting performance modifiers: a review.

    2014-07-01

    Athletes anticipatorily set and continuously adjust pacing strategies before and during events to produce optimal performance. Self-regulation ensures maximal effort is exerted in correspondence with the end point of exercise, while preventing physiological changes that are detrimental and disruptive to homeostatic control. The integration of feedforward and feedback information, together with the proposed brain's performance modifiers is said to be fundamental to this anticipatory and continuous regulation of exercise. The manipulation of central, regulatory internal and external stimuli has been a key focus within deception research, attempting to influence the self-regulation of exercise and induce improvements in performance. Methods of manipulating performance modifiers such as unknown task end point, deceived duration or intensity feedback, self-belief, or previous experience create a challenge within research, as although they contextualize theoretical propositions, there are few ecological and practical approaches which integrate theory with practice. In addition, the different methods and measures demonstrated in manipulation studies have produced inconsistent results. This review examines and critically evaluates the current methods of how specific centrally controlled performance modifiers have been manipulated, within previous deception studies. From the 31 studies reviewed, 10 reported positive effects on performance, encouraging future investigations to explore the mechanisms responsible for influencing pacing and consequently how deceptive approaches can further facilitate performance. The review acts to discuss the use of expectation manipulation not only to examine which methods of deception are successful in facilitating performance but also to understand further the key components used in the regulation of exercise and performance.

  20. Global Electrophonic Fireball Survey a review of witness reports - I

    Vinkovic, D; Lim, P L; Kovacic, D; Zgrablic, G; Andreic, Z

    2002-01-01

    Despite more than 300 years since its first scientific description, the phenomenon of electrophonic sounds from meteors are still eluding complete physical explanation. According to the accepted knowledge, the sound itself is created by strong electric fields on the ground induced by the meteor. Nonetheless, there is no convincing theory that can fully explain how a meteor can generate such a strong electric field. Extreme rareness of the phenomenon has prevented a substantial experimental work so far; thus, consequently, it remains on the margins of scientific interest. This is quite unfortunate since these electric fields suggest existence of a highly complex electromagnetic coupling and charge dynamics between the meteors and the ionosphere. Therefore, the existing theoretical work relies mostly on the witness reports. The Global Electrophonic Fireball Survey (GEFS) is the first systematic survey of witness reports of these sounds with a standardized questionnaire designed exclusively for this phenomenon. ...

  1. Individual Performance Management: A Review of Current Practices

    2013-05-01

    Full Text Available This paper provides a review of current practice in relation to individual performance management systems and process within the traditional business environment. There is a consensus that the role of the individual is central to the overall performance of any organization and how individual performances are managed and evaluated can have significant impacts on overall organizational success. Many organizations employ the traditional performance appraisal in order to monitor and assess individual employee performances. However, new approaches, such as 360-degree feedback have also become commonplace within the business environment. An analysis of each approach including benefits and challenges associated with each process is presented within this paper.

    2015-01-01

    A large number of haptic driver support systems have been described in the scientific literature. However, there is little consensus regarding the design, evaluation methods, and effectiveness of these systems. This literature survey aimed to investigate: (1) what haptic systems (in terms of function, haptic signal, channel, and supported task) have been experimentally tested, (2) how these haptic systems have been evaluated, and (3) their reported effects on driver performance and behaviour. We reviewed empirical research in which participants had to drive a vehicle in a real or simulated environment, were able to control the heading and/or speed of the vehicle, and a haptic signal was provided to them. The results indicated that a clear distinction can be made between warning systems (using vibrations) and guidance systems (using continuous forces). Studies typically used reaction time measures for evaluating warning systems and vehicle-centred performance measures for evaluating guidance systems. In general, haptic warning systems reduced the reaction time of a driver compared to no warnings, although these systems may cause annoyance. Guidance systems generally improved the performance of drivers compared to non-aided driving, but these systems may suffer from after-effects. Longitudinal research is needed to investigate the transfer and retention of effects caused by haptic support systems.

    Organized Autotelescopes for Serendipitous Event Survey (OASES) is an optical observation project that aims to detect and investigate stellar occultation events by kilometer-sized trans-Neptunian objects (TNOs). In this project, multiple low-cost observation systems for wide-field and high-speed photometry were developed in order to detect rare and short-timescale stellar occultation events. The observation system consists of commercial off-the-shelf 0.28 m aperture f/1.58 optics providing a 2.3 × 1.8° field of view. A commercial CMOS camera is coupled to the optics to obtain full-frame imaging with a frame rate greater than 10 Hz. As of 2016 September, this project exploits two observation systems, which are installed on Miyako Island, Okinawa, Japan. Recent improvements in CMOS technology in terms of high-speed imaging and low readout noise mean that the observation systems are capable of monitoring ∼2000 stars in the Galactic plane simultaneously with magnitudes down to V ∼ 13.0, providing ∼20% photometric precision in light curves with a sampling cadence of 15.4 Hz. This number of monitored stars is larger than for any other existing instruments for coordinated occultation surveys. In addition, a precise time synchronization method needed for simultaneous occultation detection is developed using faint meteors. The two OASES observation systems are executing coordinated monitoring observations of a dense stellar field in order to detect occultations by kilometer-sized TNOs for the first time.

    Directory of Open Access Journals (Sweden)

    Bill Appelbe

    1996-01-01

    Full Text Available Applications programming for high-performance computing is notoriously difficult. Al-though parallel programming is intrinsically complex, the principal reason why high-performance computing is difficult is the lack of effective software tools. We believe that the lack of tools in turn is largely due to market forces rather than our inability to design and build such tools. Unfortunately, the poor availability and utilization of parallel tools hurt the entire supercomputing industry and the U.S. high performance computing initiative which is focused on applications. A disproportionate amount of resources is being spent on faster hardware and architectures, while tools are being neglected. This article introduces a taxonomy of tools, analyzes the major factors that contribute to this situation, and suggests ways that the imbalance could be redressed and the likely evolution of tools.

  14. The effect of tertiary surveys on missed injuries in trauma: a systematic review

    Directory of Open Access Journals (Sweden)

    Keijzers Gerben B

    2012-11-01

    Full Text Available Abstract Background Trauma tertiary surveys (TTS are advocated to reduce the rate of missed injuries in hospitalized trauma patients. Moreover, the missed injury rate can be a quality indicator of trauma care performance. Current variation of the definition of missed injury restricts interpretation of the effect of the TTS and limits the use of missed injury for benchmarking. Only a few studies have specifically assessed the effect of the TTS on missed injury. We aimed to systematically appraise these studies using outcomes of two common definitions of missed injury rates and long-term health outcomes. Methods A systematic review was performed. An electronic search (without language or publication restrictions of the Cochrane Library, Medline and Ovid was used to identify studies assessing TTS with short-term measures of missed injuries and long-term health outcomes. ‘Missed injury’ was defined as either: Type I any injury missed at primary and secondary survey and detected by the TTS; or Type II any injury missed at primary and secondary survey and missed by the TTS, detected during hospital stay. Two authors independently selected studies. Risk of bias for observational studies was assessed using the Newcastle-Ottawa scale. Results Ten observational studies met our inclusion criteria. None was randomized and none reported long-term health outcomes. Their risk of bias varied considerably. Nine studies assessed Type I missed injury and found an overall rate of 4.3%. A single study reported Type II missed injury with a rate of 1.5%. Three studies reported outcome data on missed injuries for both control and intervention cohorts, with two reporting an increase in Type I missed injuries (3% vs. 7%, PP=0.01. Conclusions Overall Type I and Type II missed injury rates were 4.3% and 1.5%. Routine TTS performance increased Type I and reduced Type II missed injuries. However, evidence is sub-optimal: few observational studies, non-uniform outcome

    Hospital administrators must have timely, valid, and interpretable financial information that allows them to make operational decisions in response to the threats of the changing health care environment. Aggregate indexes that reflect dimensions of hospital financial performance and simplify the information in financial ratios are needed to aid in decision making. This article reviews the development and use of hospital financial performance measures and lays the groundwork for research into deriving a multidimensional measure.

    2016-10-01

    A retrospective view on the past two decades of the field of medical image registration is presented, guided by the article "A survey of medical image registration" (Maintz and Viergever, 1998). It shows that the classification of the field introduced in that article is still usable, although some modifications to do justice to advances in the field would be due. The main changes over the last twenty years are the shift from extrinsic to intrinsic registration, the primacy of intensity-based registration, the breakthrough of nonlinear registration, the progress of inter-subject registration, and the availability of generic image registration software packages. Two problems that were called urgent already 20 years ago, are even more urgent nowadays: Validation of registration methods, and translation of results of image registration research to clinical practice. It may be concluded that the field of medical image registration has evolved, but still is in need of further development in various aspects.

    2014-01-01

    The objective was to assess effectiveness of apraxia treatments using a systematic review. In contrast to previous reviews, each study was rated as to its applicability to occupational therapy practice and its focus on occupational performance using the FAME rating system (defined by four categories: Feasibility, Appropriateness, Meaningfulness, Effectiveness). This systematic review included eight studies: four randomized controlled trials (level 1 evidence) and four pre-post designs (level 3 evidence). Three treatment approaches were reported: errorless learning with training of details; gesture training; and strategy training. FAME scores ranged from A to C. All studies reported significant treatment effects, but only one demonstrated an impact on observed occupational performance that transferred from clinic to home.

    2016-11-01

    There is a rich variety of physics underlying the fundamental gating operations for quantum information processing (QIP). A key aspect of a QIP system is how noise may enter during quantum operations and how suppressing or correcting its effects can best be addressed. Quantum control techniques have been developed to specifically address this effort, although a detailed classification of the compatibility of controls schemes with noise sources found in common quantum systems has not yet been performed. This work numerically examines the performance of modern control methods for suppressing decoherence in the presence of noise forms found in viable quantum systems. The noise-averaged process matrix for controlled one-qubit and two-qubit operations are calculated across noise found in systems driven by Markovian open quantum dynamics. Rather than aiming to describe the absolute best control scheme for a given physical circumstance, this work serves instead to classify quantum control behavior across a large class of noise forms so that opportunities for improving QIP performance may be identified.

  16. Critical review of the United Kingdom's "gold standard" survey of public attitudes to science.

    Science.gov (United States)

    Smith, Benjamin K; Jensen, Eric A

    2016-02-01

    Since 2000, the UK government has funded surveys aimed at understanding the UK public's attitudes toward science, scientists, and science policy. Known as the Public Attitudes to Science series, these surveys and their predecessors have long been used in UK science communication policy, practice, and scholarship as a source of authoritative knowledge about science-related attitudes and behaviors. Given their importance and the significant public funding investment they represent, detailed academic scrutiny of the studies is needed. In this essay, we critically review the most recently published Public Attitudes to Science survey (2014), assessing the robustness of its methods and claims. The review casts doubt on the quality of key elements of the Public Attitudes to Science 2014 survey data and analysis while highlighting the importance of robust quantitative social research methodology. Our analysis comparing the main sample and booster sample for young people demonstrates that quota sampling cannot be assumed equivalent to probability-based sampling techniques.

    2013-01-01

    Background: Eating disorders are health problems that are particularly prevalent in adolescents and young adults. They are associated with considerable physical health and psychosocial morbidity, and increased risk of mortality. We set out to conduct a systematic review to determine their effect on physical fitness in the general population and on sport performance in athletes. Methods/Design: A systematic review of the relevant peer-reviewed literature was performed. For inclusion, articles retrieved from PubMed had to be published in English between 1977 and 2013. Wherever possible, methods and reporting adhere to the guidelines outlined in the PRISMA statement. Some additional studies were retrieved from among those cited in the reference lists of included studies and from non-electronic databases. Literature searches, study selection, method and quality appraisal were performed independently by two authors, and data was synthesized using a narrative approach. Results: Of the 1183 articles retrieved, twenty-nine studies met the inclusion criteria and were consequently analysed. The available data indicate that eating disorders have a negative effect on physical fitness and sport performance by causing low energy availability, excessive loss of fat and lean mass, dehydration, and electrolyte disturbance. Discussion: Although the paucity of the available data mean that findings to date should be interpreted with caution, the information collated in this review has several practical implications. First, eating disorders have a negative effect on both physical fitness and sport performance. Second athletics coaches should be targeted for education about the risk factors of eating disorders, as deterioration in sport performance in athletes, particularly if they are underweight or show other signs of an eating disorder, may indicate the need for medical intervention. However, future studies are needed, especially to assess the direct effect of eating disorders on

    2000-05-01

    Organ donation provides a second chance for those who have experienced severe disease or injury. Unfortunately there is a huge discrepancy between the supply and demand of transplantable organs, despite the existence of sufficient numbers of potential donors. Through a review of the literature and a survey of optometry students, this article provides insight into the reasons for the shortage of corneal donors and how more corneal donors might be obtained. A survey of 200 optometry students at the University California, Berkeley, School of Optometry was conducted to augment the literature review. Seventy-six students (38% of those surveyed) completed the survey process. Results of the survey indicated that 64.5% of who responded were willing to donate body organs, while 31.6% were not. Of those not willing to donate organs, 11.8% cited religious reasons. Other personal reasons included: fear (4%), respect for the human body (7.9%), and parental disapproval (6.4%). Only 46.1% of respondents had donation stickers on their driver's licenses. The literature review and survey indicate that age, religion, culture, personality characteristics, views on death and mortality, body image, and humanitarian concerns are among the many factors that influence people's opinion concerning organ donations. Education of the public and health care professionals' awareness of the importance of obtaining corneas for donation is crucial to end the shortage of organ donors.

  1. Review of the Effects of Offshore Seismic Surveys in Cetaceans: Are Mass Strandings a Possibility?

    Science.gov (United States)

    Castellote, Manuel; Llorens, Carlos

    2016-01-01

    Displacement of cetaceans is commonly reported during offshore seismic surveys. Speculation concerning possible links between seismic survey noise and cetacean strandings is available for a dozen events but without convincing causal evidence. This lack of evidence should not be considered conclusive but rather as reflecting the absence of a comprehensive analysis of the circumstances. Current mitigation guidelines are inadequate for long-range effects such as displacements and the potential for strandings. This review presents the available information for ten documented strandings that were possibly linked to seismic surveys and recommends initial measures and actions to further evaluate this potential link.

    Teamwork in health care settings is widely recognized as an important factor in providing high-quality patient care. However, the behaviors that comprise effective teamwork, the organizational factors that support teamwork, and the relationship between teamwork and patient outcomes remain empirical questions in need of rigorous study. To identify and review survey instruments used to assess dimensions of teamwork so as to facilitate high-quality research on this topic. We conducted a systematic review of articles published before September 2012 to identify survey instruments used to measure teamwork and to assess their conceptual content, psychometric validity, and relationships to outcomes of interest. We searched the ISI Web of Knowledge database, and identified relevant articles using the search terms team, teamwork, or collaboration in combination with survey, scale, measure, or questionnaire. We found 39 surveys that measured teamwork. Surveys assessed different dimensions of teamwork. The most commonly assessed dimensions were communication, coordination, and respect. Of the 39 surveys, 10 met all of the criteria for psychometric validity, and 14 showed significant relationships to nonself-report outcomes. Evidence of psychometric validity is lacking for many teamwork survey instruments. However, several psychometrically valid instruments are available. Researchers aiming to advance research on teamwork in health care should consider using or adapting one of these instruments before creating a new one. Because instruments vary considerably in the behavioral processes and emergent states of teamwork that they capture, researchers must carefully evaluate the conceptual consistency between instrument, research question, and context.

J Strength Cond Res 30(7): 2069-2081, 2016-This study aimed to summarize evidence on masters' swimmers energetics, biomechanics, and performance gathered in selected studies. An expanded search was conducted on 6 databases, conference proceedings, and department files. Fifteen studies were selected for further analysis. A qualitative evaluation of the studies based on the Quality Index (QI) was performed by 2 independent reviewers. The studies were thereafter classified into 3 domains according to the reported data: performance (10 studies), energetics (4 studies), and biomechanics (6 studies). The selected 15 articles included in this review presented low QI scores (mean score, 10.47 points). The biomechanics domain obtained higher QI (11.5 points), followed by energetics and performance (10.6 and 9.9 points, respectively). Stroke frequency (SF) and stroke length (SL) were both influenced by aging, although SF is more affected than SL. Propelling efficiency (ηp) decreased with age. Swimming performance declined with age. The performance declines with age having male swimmers deliver better performances than female counterparts, although this difference tends to be narrow in long-distance events. One single longitudinal study is found in the literature reporting the changes in performance over time. The remaining studies are cross-sectional designs focusing on the energetics and biomechanics. Overall, biomechanics parameters, such as SF, SL, and ηp, tend to decrease with age. This review shows the lack of a solid body of knowledge (reflected in the amount and quality of the articles published) on the changes in biomechanics, energetics, and performance of master swimmers over time. The training programs for this age-group should aim to preserve the energetics as much as possible and, concurrently, improve the

    Extrapulmonary metastasis, particularly abdominal metastasis from osteogenic sarcoma, are rare and generally appear as a solid mass of calcification as the primary tumor. The aim of this case report is to document the incidence, characteristics, treatment, and prognosis of abdominal metastasis in osteosarcomas in a single institution and to review the literature. From September 1989 to December 2002, 94 children ≤16 years of age with osteosarcomas were diagnosed and treated in the Division of Pediatric Oncology, Oncology Institute, Istanbul University. Patients with abdominal metastasis were assessed. Two girls of 94 patients (2.1%) with osteosarcoma developed abdominal metastasis. One had pulmonary metastasis at diagnosis and the other had developed lung metastasis 15 months after diagnosis. They developed abdominal metastasis 4 and 3 years after diagnosis during therapy or relapse at a median duration of 16 months (1-70 months) from initial diagnosis. All patients had metastasis to various sites, mostly lung, at the time the abdominal metastasis were detected. Treatment included surgery, chemotherapy, and radiotherapy in one and only surgery in the other patient. Both patients died at a median time of 4 months (2-6 months) from the time of abdominal metastasis with progressive disease. Abdominal metastasis in osteosarcoma is a rare event, but abdomen should be investigated in case of recurrence from osteosarcoma. The outcome for these patients is dismal in this series and in the literature.

  9. Marine monitoring surveys for desalination plants-A critical review

    KAUST Repository

    Lattemann, Sabine

    2013-01-01

    Environmental impact assessment (EIA) studies are standard practice and a regulatory requirement for most new desalination projects today. However, most of the EIA studies are limited to predictive information; that is, they gather information on the project and the project\\'s environment before project implementation to make predictions about likely impacts. The EIAs may involve comprehensive studies, such as field monitoring, laboratory toxicity testing, and modeling studies. Consequently, the"surprising paucity of useful experimental data, either from laboratory tests or from field monitoring studies", which was observed by the US National Research Council in 2008, has been gradually decreasing. However, there is still a long-term research need on the site-specific effects of desalination plants after project commissioning has taken place. A main challenge of field research is the adequate design of the monitoring studies, which have to adequately distinguish the effects of the desalination project from natural processes over long periods of time. The existing monitoring studies have so far used a wide range of approaches and methods to investigate the environmental impacts of desalination plant discharges. Shortfalls are often that they are limited in scope, short-term, or localized. In essence, many studies fall short of recognizing the potentially synergetic effects of the single waste components of the discharges on marine organisms and the complexity of the potential responses by the ecosystem. While the possible risk of damage arising from the concentrate discharge to the marine environment in close proximity to the outfall is at hand, no conclusive evidence can yet be provided concerning the long-term impacts of desalination plant discharges, let alone the cumulative impacts on certain sea areas. This paper conducts a critical review of existing monitoring programs for desalination plants. Shortcomings of current practices are identified and relevant

  10. CREATINE SUPPLEMENTATION AND EXERCISE PERFORMANCE: A BRIEF REVIEW

    Directory of Open Access Journals (Sweden)

    Stephen P. Bird

    2003-12-01

    Full Text Available During the past decade, the nutritional supplement creatine monohydrate has been gaining popularity exponentially. Introduced to the general public in the early 1990s, shortly after the Barcelona Olympic Games, creatine (Cr has become one of the most widely used nutritional supplements or ergogenic aids, with loading doses as high as 20-30 g·day-1 for 5-7 days typical among athletes. This paper reviews the available research that has examined the potential ergogenic value of creatine supplementation (CrS on exercise performance and training adaptations. Short-term CrS has been reported to improve maximal power/strength, work performed during sets of maximal effort muscle contractions, single-effort sprint performance, and work performed during repetitive sprint performance. During training CrS has been reported to promote significantly greater gains in strength, fat free mass, and exercise performance primarily of high intensity tasks. However, not all studies demonstrate a beneficial effect on exercise performance, as CrS does not appear to be effective in improving running and swimming performance. CrS appears to pose no serious health risks when taken at doses described in the literature and may enhance exercise performance in individuals that require maximal single effort and/or repetitive sprint bouts

    Full Text Available Biofuels such as ethanol and biodiesel derived from living plants or animal matter can be used directly in their neat forms or as blends with their fossil counterparts in internal combustion engines. Although the properties and performance of neat biofuels have been extensively reported, this is not the case for many blends. The purpose of this review is to analyze different forms of biofuel blends that are under research and development comparing their utility and performance in the two primary classes of engines, i.e., spark ignition and compression ignition engines. The fuel properties, performance and emission characteristics, advantages and disadvantages of various fuel blends are compared and discussed. The analysis reveals certain blends possess better overall fuel properties and yield better overall performance than the neat or fossil forms.

    2012-02-01

    Using systematic review methodology, global research reporting the frequency of zoonotic bacterial pathogens, antimicrobial use (AMU) and antimicrobial resistance (AMR) in ornamental fish, and human illness due to exposure to ornamental fish, was examined. A survey was performed to elicit opinions of aquaculture-allied personnel on the frequency of AMU and AMR in ornamental fish. The most commonly reported sporadic human infections were associated with Mycobacterium marinum, while Salmonella Paratyphi B var. Java was implicated in all reported outbreaks. Aeromonas spp. were most frequently investigated (n=10 studies) in 25 studies surveying ornamental fish from various sources. High levels of resistance were reported to amoxicillin, penicillin, tetracycline and oxytetracycline, which was also in agreement with the survey respondents' views. Studies on AMU were not found in our review. Survey respondents reported frequent use of quinolones, followed by tetracyclines, nitrofurans, and aminoglycosides. Recommendations for future surveillance and public education efforts are presented.

  18. CREATINE SUPPLEMENTATION AND SWIM PERFORMANCE: A BRIEF REVIEW

    Directory of Open Access Journals (Sweden)

    Melissa J. Hopwood

    2006-03-01

    Full Text Available Nutritional supplements are popular among athletes participating in a wide variety of sports. Creatine is one of the most commonly used dietary supplements, as it has been shown to be beneficial in improving performance during repeated bouts of high-intensity anaerobic activity. This review examines the specific effects of creatine supplementation on swimming performance, and considers the effects of creatine supplementation on various measures of power development in this population. Research performed on the effect of creatine supplementation on swimming performance indicates that whilst creatine supplementation is ineffective in improving performance during a single sprint swim, dietary creatine supplementation may benefit repeated interval swim set performance. Considering the relationship between sprint swimming performance and measurements of power, the effect of creatine supplementation on power development in swimmers has also been examined. When measured on a swim bench ergometer, power development does show some improvement following a creatine supplementation regime. How this improvement in power output transfers to performance in the pool is uncertain. Although some evidence exists to suggest a gender effect on the performance improvements seen in swimmers following creatine supplementation, the majority of research indicates that male and female swimmers respond equally to supplementation. A major limitation to previous research is the lack of consideration given to the possible stroke dependant effect of creatine supplementation on swimming performance. The majority of the research conducted to date has involved examination of the freestyle swimming stroke only. The potential for performance improvements in the breaststroke and butterfly swimming strokes is discussed, with regards to the biomechanical differences and differences in efficiency between these strokes and freestyle

  19. Interval of Routine Maintenance and Maintenance Performance: A Literature Review

    Full Text Available In high-rise residential buildings, the quality of facilities management services is significant to the normal operation of the facilities. Unfortunately, lack of concern towards building maintenance, especially preventive maintenance, happens in domestic housing industry in Malaysia. Majority of the maintenance operations of condominiums suffer from lack of planning, lack of proactive maintenance plan, and lack of proper implementation. Thus, this paper reviews the implementation of preventive maintenance strategy, routine maintenance in specific. An extensive review of literature published in 1987 to 2014 is performed for the purpose of this research. The publications are sourced from journal articles, conference proceedings and books. The literature analysis confirms that the routine maintenance of facilities and building services is vital and it can be influential towards the maintenance performance. Subsequently, a theoretical framework is developed, which shows the relationship between routine maintenance of building facilities & services and maintenance performance. The building facilities & services are divided into two categories. They are essential facilities & services that ensure the safety, health, habitability, and operability of buildings; while value-added facilities & services deal with property value, return on investment, and quality living of buildings. Based on the findings, a future research is proposed, which aims to identify the appropriate routine of maintenance for the facilities and services in high-rise residential buildings to improve the maintenance performance.

    Alcohol consumption can lead to risky driving and increase the frequency of traffic accidents, injuries and mortalities. The main purpose of our study was to compare simulated driving performance between two groups of drivers, one consumed alcohol and the other not consumed, using a systematic review. In this systematic review, electronic resources and databases including Medline via Ovid SP, EMBASE via Ovid SP, PsycINFO via Ovid SP, PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINHAL) via EBSCOhost were comprehensively and systematically searched. The randomized controlled clinical trials that compared simulated driving performance between two groups of drivers, one consumed alcohol and the other not consumed, were included. Lane position standard deviation (LPSD), mean of lane position deviation (MLPD), speed, mean of speed deviation (MSD), standard deviation of speed deviation (SDSD), number of accidents (NA) and line crossing (LC) were considered as the main parameters evaluating outcomes. After title and abstract screening, the articles were enrolled for data extraction and they were evaluated for risk of biases. Thirteen papers were included in our qualitative synthesis. All included papers were classified as high risk of biases. Alcohol consumption mostly deteriorated the following performance outcomes in descending order: SDSD, LPSD, speed, MLPD, LC and NA. Our systematic review had troublesome heterogeneity. Alcohol consumption may decrease simulated driving performance in alcohol consumed people compared with non-alcohol consumed people via changes in SDSD, LPSD, speed, MLPD, LC and NA. More well-designed randomized controlled clinical trials are recommended. Copyright © 2017. Production and hosting by Elsevier B.V.

  5. A Review of Screw Conveyors Performance Evaluation During Handling Process

    Directory of Open Access Journals (Sweden)

    Hemad Zareiforoush

    2010-04-01

    Full Text Available This paper reviews recent work on screw conveyors performance evaluation during handling process, especially in the case of agricultural grains and bulk materials. Experimental work has been mainly carried out to determine a range of parameters, such as auger dimension, screw rotational speed, screw clearance, conveyor intake length and conveying angle for horizontal, inclined and vertical screw conveyors. Several measurement techniques including theoretical models and DEM have been utilized to study the screw conveyors performance. However, each of these techniques is limited in its application. Difficulties in representing vortex motion and interactions among conveying grains and between the particles and screw rotating flight have so far limited the success of advanced modeling. Further work is needed to be conducted on screw augers performance to understand and improve the agricultural grains and bulk materials handling process.

  6. A Bibliometric Analysis and Review on Performance Modeling Literature

    Barbara Livieri

    2015-04-01

    Full Text Available In management practice, performance indicators are considered as a prerequisite to make informed decisions in line with the organization’s goals. On the other hand, indicators summarizes compound phenomena in a few digits, which can induce to inadequate decisions, biased by information loss and conflicting values. Model driven approaches in enterprise engineering can be very effective to avoid these pitfalls, or to take it under control. For that reason, “performance modeling” has the numbers to play a primary role in the “model driven enterprise” scenario, together with process, information and other enterprise-related aspects. In this perspective, we propose a systematic review of the literature on performance modeling in order to retrieve, classify, and summarize existing research, identify the core authors and define areas and opportunities for future research.

  9. Impact of Dietary Antioxidants on Sport Performance: A Review.

    Science.gov (United States)

    Braakhuis, Andrea J; Hopkins, Will G

    2015-07-01

    Many athletes supplement with antioxidants in the belief this will reduce muscle damage, immune dysfunction and fatigue, and will thus improve performance, while some evidence suggests it impairs training adaptations. Here we review the effect of a range of dietary antioxidants and their effects on sport performance, including vitamin E, quercetin, resveratrol, beetroot juice, other food-derived polyphenols, spirulina and N-acetylcysteine (NAC). Older studies suggest vitamin E improves performance at altitude, with possible harmful effects on sea-level performance. Acute intake of vitamin E is worthy of further consideration, if plasma levels can be elevated sufficiently. Quercetin has a small beneficial effect for exercise of longer duration (>100 min), but it is unclear whether this benefits athletes. Resveratrol benefits trained rodents; more research is needed in athletes. Meta-analysis of beetroot juice studies has revealed that the nitrate component of beetroot juice had a substantial but unclear effect on performance when averaged across athletes, non-athletes and modes of exercise (single dose 1.4 ± 2.0%, double dose 0.5 ± 1.9%). The effect of addition of polyphenols and other components to beetroot juice was trivial but unclear (single dose 0.4 ± 3.2%, double dose -0.5 ± 3.3%). Other food-derived polyphenols indicate a range of performance outcomes from a large improvement to moderate impairment. Limited evidence suggests spirulina enhances endurance performance. Intravenous NAC improved endurance cycling performance and reduced muscle fatigue. On the basis of vitamin E and NAC studies, acute intake of antioxidants is likely to be beneficial. However, chronic intakes of most antioxidants have a harmful effect on performance.

    2013-01-01

    A national healthcare company applied the Malcolm Baldrige Criteria for Performance Excellence and its "Are We Making Progress?" survey as an annual organizational self-assessment to identify areas for improvement. For 6 years, Liberty Healthcare Corporation reviewed the survey results on an annual basis to analyze positive and negative trends, monitor company progress toward targeted goals and develop new initiatives to address emerging areas for improvement. As such, the survey provided a simple and inexpensive methodology to gain useful information from employees at all levels and from multiple service sites and business sectors. In particular, it provided a valuable framework for assessing and improving the employees' commitment to the company's mission and values, high standards and ethics, quality of work, and customer satisfaction. The methodology also helped the company to incorporate the philosophy and principles of continuous quality improvement in a unified fashion. Corporate and local leadership used the same measure to evaluate the performance of individual programs relative to each other, to the company as a whole, and to the "best practices" standard of highly successful companies that received the Malcolm Baldrige National Quality Award. © 2012 National Association for Healthcare Quality.

    2016-11-01

    In spite of the almost all-encompassing variability of Be stars, surveys play a steadily increasing role in complementing the insights gained from single-star studies. The definition of classical Be stars as recently augmented by Rivinius, Carciofi, and Martayan (2013) enables unambiguous identification of Be stars in a much increased range of observations. Results of targeted surveys are briefly reviewed for the effects of metallicity, binarity, and evolution. It still remains to be seen whether Be stars are safe benchmarks for the calibration of evolutionary models with rapid rotation.

    To summarize and then assess with a pilot study the use of published best practice recommendations for priority setting during management of multiple healthcare research projects, in a resource-constrained environment. Medical, economic, business, and operations literature was reviewed to summarize and develop a survey to assess best practices for managing multiple projects. Fifteen senior healthcare research project managers, directors, and faculty at an urban academic institution were surveyed to determine most commonly used priority rules, ranking of rules, characteristics of their projects, and availability of resources. Survey results were compared to literature recommendations to determine use of best practices. Seven priority-setting rules were identified for managing multiple projects. Recommendations on assigning priorities by project characteristics are presented. In the pilot study, a large majority of survey respondents follow best practice recommendations identified in the research literature. However, priority rules such as Most Total Successors (MTS) and Resource Scheduling Method (RSM) were used "very often" by half of the respondents when better performing priority rules were available. Through experience, project managers learn to manage multiple projects under resource constraints. Best practice literature can assist project managers in priority setting by recommending the most appropriate priority given resource constraints and project characteristics. There is room for improvement in managing multiple projects.

    2014-12-01

    Team handball is a complex sport game that is determined by the individual performance of each player as well as tactical components and interaction of the team. The aim of this review was to specify the elements of team-handball performance based on scientific studies and practical experience, and to convey perspectives for practical implication. Scientific studies were identified via data bases of PubMed, Web of Knowledge, SPORT Discus, Google Scholar, and Hercules. A total of 56 articles met the inclusion criteria. In addition, we supplemented the review with 13 additional articles, proceedings and book sections. It was found that the specific characteristics of team-handball with frequent intensity changes, team-handball techniques, hard body confrontations, mental skills and social factors specify the determinants of coordination, endurance, strength and cognition. Although we found comprehensive studies examining individual performance in team-handball players of different experience level, sex or age, there is a lack of studies, particularly for team-handball specific training, as well as cognition and social factors. Key PointsThe specific characteristics of team-handball with frequent intensity changes, specific skills, hard body confrontations, mental skills and social factors define the determinants of coordination, endurance, strength and cognition.To increase individual and team performance in team-handball specific training based on these determinants have been suggested.Although there are comprehensive studies examining individual performance in team-handball players of different experience level, sex, or age are published, there is a lack of training studies, particularly for team-handball specific techniques and endurance, as well as cognition and social factors.

    2016-01-01

    We have performed a detailed survey simulation of the LSST performance with regards to near-Earth objects (NEOs) using the project's current baseline cadence. The survey shows that if the project is able to reliably generate linked sets of positions and times (a so-called "tracklet") using two detections of a given object per night and can link these tracklets into a track with a minimum of 3 tracklets covering more than a ~12 day length-of-arc, they would be able to discover 62% of the potentially hazardous asteroids (PHAs) larger than 140 m in its projected 10 year survey lifetime. This completeness would be reduced to 58% if the project is unable to implement a pipeline using the two detection cadence and has to adopt the four detection cadence more commonly used by existing NEO surveys. When including the estimated performance from the current operating surveys, assuming these would continue running until the start of LSST and perhaps beyond, the completeness fraction for PHAs larger than 140m would be 73...

Declaring a collaborative and innovative perspective in the mission and vision of a company is not sufficient. It is necessary to measure the process and results to justify investments in research and development and ensure continuity of the company's success. Over the years, researchers proposed various models for measuring the performance of collaborative innovation within companies. The purpose of this article is to review the existing literature on collaborative innovation network in order to identify the main approach used for measuring its performance. As many studies show, notable results were obtained in the case of multinational corporations (MNCs. MNCs are seen as the main vehicle for innovation. They are the first who developed international network of collaborative innovation based on research and development expenses. As a result, we first focus on the motives for which MNCs are considered the main developers of these networks. Furthermore we discuss the existing literature for measuring performance of collaborative innovation networks and, at last, we develop a model for evaluating collaborative innovation performance based on previous research.

    Ibáñez, Pablo García-Risueño Pablo E

    2012-01-01

    The increase of existing computational capabilities has made simulation emerge as a third discipline of Science, lying midway between experimental and purely theoretical branches [1, 2]. Simulation enables the evaluation of quantities which otherwise would not be accessible, helps to improve experiments and provides new insights on systems which are analysed [3-6]. Knowing the fundamentals of computation can be very useful for scientists, for it can help them to improve the performance of their theoretical models and simulations. This review includes some technical essentials that can be useful to this end, and it is devised as a complement for researchers whose education is focused on scientific issues and not on technological respects. In this document we attempt to discuss the fundamentals of High Performance Computing (HPC) [7] in a way which is easy to understand without much previous background. We sketch the way standard computers and supercomputers work, as well as discuss distributed computing and di...

    2006-01-01

    Full Text Available Abstract Background Although the methods for conducting systematic reviews of efficacy are well established, there is much less guidance on how systematic reviews of adverse effects should be performed. Methods In order to determine where methodological research is most needed to improve systematic reviews of adverse effects of health care interventions, we conducted a descriptive analysis of systematic reviews published between 1994 and 2005. We searched the Database of Abstracts of Reviews of Effects (DARE and The Cochrane Database of Systematic Reviews (CDSR to identify systematic reviews in which the primary outcome was an adverse effect or effects. We then extracted data on many of the elements of the systematic review process including: types of interventions studied, adverse effects of interest, resources searched, search strategies, data sources included in reviews, quality assessment of primary data, nature of the data analysis, and source of funding. Results 256 reviews were included in our analysis, of which the majority evaluated drug interventions and pre-specified the adverse effect or effects of interest. A median of 3 resources were searched for each review and very few reviews (13/256 provided sufficient information to reproduce their search strategies. Although more than three quarters (185/243 of the reviews sought to include data from sources other than randomised controlled trials, fewer than half (106/256 assessed the quality of the studies that were included. Data were pooled quantitatively in most of the reviews (165/256 but heterogeneity was not always considered. Less than half (123/256 of the reviews reported on the source of funding. Conclusion There is an obvious need to improve the methodology and reporting of systematic reviews of adverse effects. The methodology around identification and quality assessment of primary data is the main concern.

    Green roofs reduce runoff from impervious surfaces in urban development. This paper reviews the technical literature on green roof hydrology. Laboratory experiments and field measurements have shown that green roofs can reduce stormwater runoff volume by 30 to 86%, reduce peak flow rate by 22 to 93% and delay the peak flow by 0 to 30 min and thereby decrease pollution, flooding and erosion during precipitation events. However, the effectiveness can vary substantially due to design characteristics making performance predictions difficult. Evaluation of the most recently published study findings indicates that the major factors affecting green roof hydrology are precipitation volume, precipitation dynamics, antecedent conditions, growth medium, plant species, and roof slope. This paper also evaluates the computer models commonly used to simulate hydrologic processes for green roofs, including stormwater management model, soil water atmosphere and plant, SWMS-2D, HYDRUS, and other models that are shown to be effective for predicting precipitation response and economic benefits. The review findings indicate that green roofs are effective for reduction of runoff volume and peak flow, and delay of peak flow, however, no tool or model is available to predict expected performance for any given anticipated system based on design parameters that directly affect green roof hydrology.

    1993-08-01

    The purpose of this paper is to recommend regulatory guidance for reviewers examining real-time performance of computer-based safety systems used in nuclear power plants. Three areas of guidance are covered in this report. The first area covers how to determine if, when, and what prototypes should be required of developers to make a convincing demonstration that specific problems have been solved or that performance goals have been met. The second area has recommendations for timing analyses that will prove that the real-time system will meet its safety-imposed deadlines. The third area has description of means for assessing expected or actual real-time performance before, during, and after development is completed. To ensure that the delivered real-time software product meets performance goals, the paper recommends certain types of code-execution and communications scheduling. Technical background is provided in the appendix on methods of timing analysis, scheduling real-time computations, prototyping, real-time software development approaches, modeling and measurement, and real-time operating systems.

    Full Text Available Adoption of new technology in building inspection works has proven to be very crucial and has improved efficiency and effectiveness in this regards. Tools and techniques in building inspection and condition survey continuously evolved trough times. The tools and techniques adopted mostly first has been successfully applied by others technical field such as civil engineering, manufacturing etc.. As UAS has been successfully adopted by many technical professions such as geotechnical engineering, land surveying, civil engineering etc. a practical use of UAV for building surveying and facilities management yet to explored. The present paper intend to explore the viability of UAS application for building inspection with the advantage it has especially in inspecting and collecting data at difficult to reach area such as roof, ceiling, gutter and recording data for large building complex. With the accurate and comprehensive inspection data collected, perhaps it could guide building surveyors or facilities managers in diagnosing building defect effectively, suggesting possible remedies, solving issues and making decision precisely. The present paper provides a comprehensive review of possible application of small UAS in building inspection and facilities management related uses by reviewing the similar application and identifying their features that suits facilities management’s nature of practice. Challenges faced by building and facilities management organisation to apply UAS in their building condition survey routine that are identifying suitable tools other than normal visual tools to be attached, finalising arrangement on site during inspection and limited skill of existing personnel to deal with the equipments.

    Post-exercise massage is one of the most frequently applied interventions to enhance recovery of athletes. However, evidence to support the efficacy of massage for performance recovery is scarce. Moreover, it has not yet been concluded under which conditions massage is effective. The objective of this study was to perform a systematic review and meta-analysis of the available literature on massage for performance recovery. We conducted a structured literature search and located 22 randomized controlled trials. These were analysed with respect to performance effects and various characteristics of the study design (type and duration of massage, type of exercise and performance test, duration of recovery period, training status of subjects). Of the 22 studies, 5 used techniques of automated massage (e.g., vibration), while the other 17 used classic manual massage. A tendency was found for shorter massage (5-12 min) to have larger effects (+6.6%, g = 0.34) than massage lasting more than 12 min (+1.0%, g = 0.06). The effects were larger for short-term recovery of up to 10 min (+7.9%, g = 0.45) than for recovery periods of more than 20 min (+2.4%, g = 0.08). Although after high-intensity mixed exercise, massage yielded medium positive effects (+14.4%, g = 0.61), the effects after strength exercise (+3.9%, g = 0.18) and endurance exercise (+1.3%, g = 0.12) were smaller. Moreover, a tendency was found for untrained subjects to benefit more from massage (+6.5%, g = 0.23) than trained athletes (+2.3%, g = 0.17). The effects of massage on performance recovery are rather small and partly unclear, but can be relevant under appropriate circumstances (short-term recovery after intensive mixed training). However, it remains questionable if the limited effects justify the widespread use of massage as a recovery intervention in competitive athletes.

    Anaemia defined as a haemoglobin level <13 g/dl in men and <12 g/dl in women is common in older people and associated with numerous health consequences. The aim of this study was to systematically review all published data from the past 30 years that studied the association between anaemia and cognitive performance in people aged 65 years and over. An English and French Medline and Cochrane Library search ranging from 1979 to 2011 indexed under the Medical Subject Heading (MeSH) terms 'haemoglobin' or 'anaemia' combined with the terms 'dementia' or 'cognition disorders' or 'memory disorders' or 'orientation' or 'executive functions' or 'attention' or 'brain' or 'neuropsychological tests' was performed. Ninety-eight studies were selected. The following specific conditions were excluded: cancer, chronic kidney diseases, chronic heart disease and post-operative cognitive dysfunction. Five observational studies and six prospective cohort studies were included in the final analysis. According to the studies, the number of participants ranged from 302 to 2250 community-dwelling older people aged 55 years or over. Four studies considered the association between haemoglobin concentration and global cognitive functions, another three examined the association between haemoglobin concentration and the incidence of dementia, and four studies evaluated some specific aspects of cognition. A significant positive association was shown between anaemia and global cognitive decline as well as the incidence of dementia. A significant association was also shown between anaemia and executive functions. This systematic review shows a probable association between anaemia and cognitive performances, particularly with executive functions.

    Full Text Available This article reviews major national population sex surveys that have asked questions about homosexuality focusing on conceptual and methodological issues, including the definitions of sex, the measured aspects of homosexuality, sampling and interviewing technique, and questionnaire design. Reported rates of major measures of same-sex attraction, behavior, partners, and sexual identity from surveys are also presented and compared. The study of homosexuality in surveys has been shaped by the research traditions and questions ranging from sexology to the epidemiology of HIV/AIDS. Sexual behavior has been a central topic at least since Kinsey. Issues of sexual attraction and/or orientation and sexual identity have emerged more recently. Differences in the treatment of men and women in the design and analysis of surveys as well as in the reported rates in different surveys, in different countries and time periods are also presented and discussed. We point out the importance of the consideration of both methodological and social change issues in assessing such differences.

  14. Are peer reviewers encouraged to use reporting guidelines? A survey of 116 health research journals.

    Directory of Open Access Journals (Sweden)

    Allison Hirst

    Full Text Available Pre-publication peer review of manuscripts should enhance the value of research publications to readers who may wish to utilize findings in clinical care or health policy-making. Much published research across all medical specialties is not useful, may be misleading, wasteful and even harmful. Reporting guidelines are tools that in addition to helping authors prepare better manuscripts may help peer reviewers in assessing them. We examined journals' instructions to peer reviewers to see if and how reviewers are encouraged to use them.We surveyed websites of 116 journals from the McMaster list. Main outcomes were 1 identification of online instructions to peer reviewers and 2 presence or absence of key domains within instructions: on journal logistics, reviewer etiquette and addressing manuscript content (11 domains.Only 41/116 journals (35% provided online instructions. All 41 guided reviewers about the logistics of their review processes, 38 (93% outlined standards of behaviour expected and 39 (95% contained instruction about evaluating the manuscript content. There was great variation in explicit instruction for reviewers about how to evaluate manuscript content. Almost half of the online instructions 19/41 (46% mentioned reporting guidelines usually as general statements suggesting they may be useful or asking whether authors had followed them rather than clear instructions about how to use them. All 19 named CONSORT for reporting randomized trials but there was little mention of CONSORT extensions. PRISMA, QUOROM (forerunner of PRISMA, STARD, STROBE and MOOSE were mentioned by several journals. No other reporting guideline was mentioned by more than two journals.Although almost half of instructions mentioned reporting guidelines, their value in improving research publications is not being fully realised. Journals have a responsibility to support peer reviewers. We make several recommendations including wider reference to the EQUATOR Network

    To harmonize measures of cognitive performance using item response theory (IRT) across two international aging studies. Data for persons ≥65 years from the Health and Retirement Study (HRS, N = 9,471) and the English Longitudinal Study of Aging (ELSA, N = 5,444). Cognitive performance measures varied (HRS fielded 25, ELSA 13); 9 were in common. Measurement precision was examined for IRT scores based on (a) common items, (b) common items adjusted for differential item functioning (DIF), and (c) DIF-adjusted all items. Three common items (day of date, immediate word recall, and delayed word recall) demonstrated DIF by survey. Adding survey-specific items improved precision but mainly for HRS respondents at lower cognitive levels. IRT offers a feasible strategy for harmonizing cognitive performance measures across other surveys and for other multi-item constructs of interest in studies of aging. Practical implications depend on sample distribution and the difficulty mix of in-common and survey-specific items. © The Author(s) 2015.

  16. Exploring perceived organisational formalisation and performance review system complexity as predictors of executive alienation in performance review systems

    Directory of Open Access Journals (Sweden)

    S. Senthil Ganesh

    2011-12-01

    Full Text Available A number of discussions in organisation literature have focused on the alienating effect of formalisation on managerial as well as non-managerial employees. Most of the research studies have found support for the direct influence of formalisation on alienation, both positively as well as negatively. A few studies have found that formalisation did not have a direct influence on alienation but through the effects of other variables like role conflict, role ambiguity and organisational identification. We examined whether perceived performance review system complexity would predict variance in executive alienation beyond that predicted by perceived organisational formalisation in earlier studies. A total of 477 executives participated in a study that examined the factors associated with executive alienation. The outcome of our assessment shows that while there is no significant direct influence of perceived organisational formalisation on executive alienation, it has an indirect effect on executive alienation through perceived performance review system complexity. Based on the outcome, we discuss the implications for future research and practice.

    To summarize previously published findings and to present the opinions of a group of reconstructive orthopedic surgeons from a single institution on participation in sports after hip or knee arthroplasty. We reviewed the literature pertaining to participation in sports after hip or knee arthroplasty and surveyed a group of orthopedic surgeons about their recommendations for resumption of various sports activities by patients who had undergone total hip or knee arthroplasty. A computerized literature search was performed, and salient issues about participation in sports after joint replacement procedures were synthesized. At the Mayo Clinic, 28 orthopedic surgeons (13 consultants and 15 fellows or residents) completed a single-page questionnaire that requested a recommendation ("yes," "no," or "depends") about patients resuming participation in 28 common sports after recovery from total hip or knee arthroplasty. Staff surgeon responses were compared with responses from fellows and residents by using the Mann-Whitney U test. Sports in which 75% of surgeons would not allow participation were identified as "not recommended," whereas sports in which 75% of surgeons would allow participation were labeled as "recommended." Fellows and residents were less likely than staff surgeons to allow return to cross-country skiing after total knee arthroplasty. Otherwise, responses from consultant surgeons and from fellows and residents did not differ significantly. Recommended sports included sailing, swimming laps, scuba diving, cycling, golfing, and bowling after hip and knee replacement procedures and also cross-country skiing after knee arthroplasty. Sports not recommended after hip or knee arthroplasty were running, waterskiing, football, baseball, basketball, hockey, handball, karate, soccer, and racquetball. After hip or knee arthroplasty, participation in no-impact or low-impact sports can be encouraged, but participation in high-impact sports should be prohibited.

    To determine the association between professors' self-perception of mentoring skills and their academic performance. Two hundred and fifteen professors from Imperial College London, the first Academic Health Science Centre (AHSC) in the UK, were surveyed. The instrument adopted was the Mentorship Skills Self-Assessment Survey. Statement scores were aggregated to provide a score for each shared core, mentor-specific and mentee-specific skill. Univariate and multivariate regression analyses were used to evaluate their relationship with quantitative measures of academic performance (publications, citations and h-index). There were 104 professors that responded (response rate 48%). There were no statistically significant negative correlations between any mentoring statement and any performance measure. In contrast, several mentoring survey items were positively correlated with academic performance. The total survey score for frequency of application of mentoring skills had a statistically significant positive association with number of publications (B=0.012, SE=0.004, p=0.006), as did the frequency of acquiring mentors with number of citations (B=1.572, SE=0.702, p=0.030). Building trust and managing risks had a statistically significant positive association with h-index (B=0.941, SE=0.460, p=0.047 and B=0.613, SE=0.287, p=0.038, respectively). This study supports the view that mentoring is associated with high academic performance. Importantly, it suggests that frequent use of mentoring skills and quality of mentoring have positive effects on academic performance. Formal mentoring programmes should be considered a fundamental part of all AHSCs' configuration. Published by the BMJ Publishing Group Limited.

    The National Renewable Energy Laboratory (NREL) has a major responsibility in the implementation of the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program. Sandia National Laboratories (SNL) has a major role in supporting inverter development, characterization, standards, certifications, and verifications. The Solar Energy Technologies Program recently published a Multiyear Technical Plan, which establishes a goal of reducing the Levelized Energy Cost (LEC) for photovoltaic (PV) systems to $0.06/kWh by 2020. The Multiyear Technical Plan estimates that, in order to meet the PV system goal, PV inverter prices will need to decline to $0.25-0.30 Wp by 2020. DOE determined the need to conduct a rigorous review of the PV Program's technical and economic targets, including the target set for PV inverters. NREL requested that Navigant Consulting Inc.(NCI) conduct a review of historical and projected cost and performance improvements for PV inverters, including identification of critical barriers identified and the approaches government might use to address them.

    Full Text Available Today India is a fast developing economy; its GDP is increasing so the per capita income is also increasing. To meet the comfort requirements, especially in scorching summer and chilling winter in one form or other, we need modern amenities like air-conditioners and room heaters. Both need energy (electricity as a fuel to perform their function, so at individual level or at national view point, energy saving has to be done. The phrase will not be wrong: “Let the energy be saved, though the heaven falls”. In this paper, a review of insulation materials along with their properties has been presented. The information given is relevant and useful for architects and engineers. This paper also has glimpses of past and future of insulating materials.

    Though substantial coal-washing activities are carried out in a tropical climate, in the 70-yr history of coal flotation, the effect of diurnal and seasonal variations in temperature as an operational variable has received only limited attention. This review examines the current knowledge on the effect of temperature on coal flotation performance and finds that coals with strong natural hydrophobicity do not seem to be affected by a variation in pulp temperature. Difficult-to-float coals, however, appear to float well within a temperature range of 20 - 35{degree}C with considerable improvement in all flotation indices, concentrate yield and ash, recovery of combustibles, flotation rate, and tailing ash as compared to their values at higher or lower temperature.

    Beedie, Christopher J; Foad, Abigail J

    2009-01-01

    The placebo effect, with its central role in clinical trials, is acknowledged as a factor in sports medicine, although until recently little has been known about the likely magnitude and extent of the effect in any specific research setting. Even less is known about the prevalence of the effect in competitive sport. The present paper reviews 12 intervention studies in sports performance. All examine placebo effects associated with the administration of an inert substance believed by subjects to be an ergogenic aid. Placebo effects of varying magnitudes are reported in studies addressing sports from weightlifting to endurance cycling. Findings suggest that psychological variables such as motivation, expectancy and conditioning, and the interaction of these variables with physiological variables, might be significant factors in driving both positive and negative outcomes. Programmatic research involving the triangulation of data, and investigation of contextual and personality factors in the mediation of placebo responses may help to advance knowledge in this area.

  8. Towards harmonisation of critical laboratory result management - review of the literature and survey of australasian practices.

    2012-11-01

    Timely release and communication of critical test results may have significant impact on medical decisions and subsequent patient outcomes. Laboratories therefore have an important responsibility and contribution to patient safety. Certification, accreditation and regulatory bodies also require that laboratories follow procedures to ensure patient safety, but there is limited guidance on best practices. In Australasia, no specific requirements exist in this area and critical result reporting practices have been demonstrated to be heterogeneous worldwide.Recognising the need for agreed standards and critical limits, the AACB started a quality initiative to harmonise critical result management throughout Australasia. The first step toward harmonisation is to understand current laboratory practices. Fifty eight Australasian laboratories responded to a survey and 36 laboratories shared their critical limits. Findings from this survey are compared to international practices reviewed in various surveys conducted elsewhere. For the successful operation of a critical result management system, critical tests and critical limits must be defined in collaboration with clinicians. Reporting procedures must include how critical results are identified; who can report and who can receive critical results; what is an acceptable timeframe within which results must be delivered or, if reporting fails, what escalation procedures should follow; what communication channels or systems should be used; what should be recorded and how; and how critical result procedures should be maintained and evaluated to assess impact on outcomes.In this paper we review the literature of current standards and recommendations for critical result management. Key elements of critical result reporting are discussed in view of the findings of various national surveys on existing laboratory practices, including data from our own survey in Australasia. Best practice recommendations are made that laboratories

    Skeletal surveys for non-accidental trauma (NAT) include lateral spinal and pelvic views, which have a significant radiation dose. To determine whether pelvic and lateral spinal radiographs should routinely be performed during initial bone surveys for suspected NAT. The radiology database was queried for the period May 2005 to May 2011 using CPT codes for skeletal surveys for suspected NAT. Studies performed for skeletal dysplasia and follow-up surveys were excluded. Initial skeletal surveys were reviewed to identify fractures present, including those identified only on lateral spinal and/or pelvic radiographs. Clinical information and MR imaging was reviewed for the single patient with vertebral compression deformities. Of the 530 children, 223 (42.1%) had rib and extremity fractures suspicious for NAT. No fractures were identified solely on pelvic radiographs. Only one child (<0.2%) had vertebral compression deformities identified on a lateral spinal radiograph. This infant had rib and extremity fractures and was clinically paraplegic. MR imaging confirmed the vertebral body fractures. Since no fractures were identified solely on pelvic radiographs and on lateral spinal radiographs in children without evidence of NAT, nor in nearly all with evidence of NAT, inclusion of these views in the initial evaluation of children for suspected NAT may not be warranted.

  10. Physiological fitness and professional classical ballet performance: a brief review.

    2009-12-01

    Although classical ballet is an artistic expression through the use of the body, there is a real opportunity to improve and extend the dancer's career by simply applying sports science principles to dance training and performance. Dance training is a long process of physical, intellectual, and psychological preparation, through physical exercise, often beginning in childhood and continuing until retirement. Fitness programs, supplementary to traditional dance classes, have only recently been considered as a part of this process; it may be suggested that this cross-training has generally been avoided thus far because of tradition and a reluctance to follow principles associated with sport. Classical ballet training, rehearsal, and performance do not elicit significant stimulus to result in increased aerobic fitness levels. Therefore, dancers often demonstrate low levels of aerobic fitness even though a strong aerobic foundation is necessary to meet the required workload. Dancers have greater than average range of motion and strength at the hip joint but weaknesses in the upper body, torso, hamstrings, and quadriceps. In the past, dancers have been wary of strength training because they perceive this leads to aesthetically undesirable hypertrophy. Dancers also have low body weights and low percentage body fat. Given that training does not provide the opportunity to expend enough energy to maintain these aesthetic demands, this aesthetic demand may be met by caloric restriction, which may lead to subsequent increased injury risk. It has been hypothesized that a "fit for purpose" body can help improve performance, reduce the risk of injury, and ensure prolonged dance careers. This review aims to explore the extent to which physical fitness components relate to dance performance, in particular classical ballet.

    Pathology as a basic science discipline traditionally is a component of the preclinical medical school curriculum. While there have been regional and nationwide surveys reporting on the curricular organization and instructional formats of preclinical pathology instruction, the extent of required pathology integration into the clinical medical school curriculum, particularly as it relates to practical issues of patient management, has not been studied. A survey soliciting information about required pathology programs in the clinical years was distributed to the members of the Undergraduate Medical Educators Section of the Association of Pathology Chairs (APC). A literature search of such programs was also performed. Thirty-seven respondents representing 30 medical schools (21% of the 140 Liaison Committee on Medical Education-accredited medical schools in the APC) described a total of 16 required pathology programs in the clinical years. An additional 10 programs were identified in the literature. Advantages of required pathology activities in the clinical years include educating medical students in effective utilization of anatomic and clinical pathology for patient care and exposing them to the practice of pathology. Reported challenges have been competition for curricular time in the clinical years, attitudinal resistance by clerkship directors, failure to recognize pathology as a clinical discipline, and insufficient number of faculty in pathology departments. By survey sample and literature review, there has been relatively little progress in the integration of required pathology exposure into the clinical years. Development of practice-related pathology competencies may facilitate introduction of such curricular programs in the future.

    Gunukula Sameer K

    2010-07-01

    Full Text Available Abstract Background The primary objective was to systematically review the medical literature for instruments validated for use in epidemiological and clinical research on waterpipe smoking. Methods We searched the following databases: MEDLINE, EMBASE, and ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included papers reporting on the development and/or validation of survey instruments to measure waterpipe tobacco consumption or related concepts. Two reviewers used a standardized and pilot tested data abstraction form to collect data from each eligible study using a duplicate and independent screening process. We also determined the percentage of observational studies assessing the health effects of waterpipe tobacco smoking and the percentage of studies of prevalence of waterpipe tobacco smoking that have used validated survey instruments. Results We identified a total of five survey instruments. One instrument was designed to measure knowledge, attitudes, and waterpipe use among pregnant women and was shown to have internal consistency and content validity. Three instruments were designed to measure waterpipe tobacco consumption, two of which were reported to have face validity. The fifth instrument was designed to measure waterpipe dependence and was rigorously developed and validated. One of the studies of prevalence and none of the studies of health effects of waterpipe smoking used validated instruments. Conclusions A number of instruments for measuring the use of and dependence on waterpipe smoking exist. Future research should study content validity and cross cultural adaptation of these instruments.

    Full Text Available HPLC is the most versatile and widely used elution chromatography. The technique is used to resolve and determine species in a variety of organic, inorganic, biological, ionic and polymeric materials. Detector is the heart of an instrument and efficiency of system is dependent upon detecting techniques. Many types of HPLC detectors exist, each of which has some valuable performance feature such as refractive index detector, ultraviolet detector, fluorescent detector, electrochemical detector, electric conductivity detector, liquid light scattering detector, evaporative light scattering detector. Due to strong requirement for improvements in sensitivity, selectivity and other performance characteristics of the detector recent developments in conventional techniques and some other new technologies have been adopted such as laser light scattering detector, charged aerosol detector, nano quantity aerosol detector, chiral detector and pulsed amperometric detector. These detectors provide accurate concentration analysis, excellent sensitivity, wide dynamic range, consistent response and broad applicability of the drug components. Working of these detectors involve different principles such as optical techniques, aerosol based techniques, refractive methods, light scattering principle, amperometric and fluorescence. The present review enlightens both conventional and advanced techniques and compares their capabilities of analyzing drug components and need for new techniques for better and wide range of applicability.

  17. Performance Parameters and Characterizations of Nanocrystals: A Brief Review

    Directory of Open Access Journals (Sweden)

    Manasi M. Chogale

    2016-08-01

    Full Text Available Poor bioavailability of drugs associated with their poor solubility limits the clinical effectiveness of almost 40% of the newly discovered drug moieties. Low solubility, coupled with a high log p value, high melting point and high dose necessitates exploration of alternative formulation strategies for such drugs. One such novel approach is formulation of the drugs as “Nanocrystals”. Nanocrystals are primarily comprised of drug and surfactants/stabilizers and are manufactured by “top-down” or “bottom-up” methods. Nanocrystals aid the clinical efficacy of drugs by various means such as enhancement of bioavailability, lowering of dose requirement, and facilitating sustained release of the drug. This effect is dependent on the various characteristics of nanocrystals (particle size, saturation solubility, dissolution velocity, which have an impact on the improved performance of the nanocrystals. Various sophisticated techniques have been developed to evaluate these characteristics. This article describes in detail the various characterization techniques along with a brief review of the significance of the various parameters on the performance of nanocrystals.

    Full Text Available Abstract Objective The AAP recommends that a follow-up skeletal survey be obtained for all children Methods A retrospective review of radiology records from September 1, 1998 - January 31, 2007 was conducted. Suspected victims of child abuse who were Results Forty-seven children had a negative initial skeletal survey and were included for analysis. The mean age was 6.9 months (SD 5.7; the mean number of days between skeletal surveys was 18.7 (SD 10.1 Four children (8.5% had signs of healing bone trauma on a follow-up skeletal survey. Three of these children (75% had healing rib fractures and one child had a healing proximal humerus fracture. The findings on the follow-up skeletal survey yielded forensically important information in all 4 cases and strengthened the diagnosis of non-accidental trauma. Conclusion 8.5 percent of children with negative initial skeletal surveys had forensically important findings on follow-up skeletal survey that increased the certainty of the diagnosis of non-accidental trauma. A follow-up skeletal survey can be useful even when the initial skeletal survey is negative.

    In this survey, licensing procedures for the implementation of different kinds of components and systems in nuclear power plants have been studied in four European countries: Belgium (Finland), Germany, and Switzerland. The main focus has been to describe the general features of the licensing procedures for electrical and for instrumentation and control (IandC) equipment and systems. The regulatory framework for the operation of nuclear power plants in Belgium is based on the American regulations. The licensing procedure for each modification of significance for the safety of a plant is carried out by the authorised inspection organisation (AVN), which follows its own procedures for the review of the modification file, the commissioning, and conformity check of the installation. These procedures are general and independent of the technical domain of the equipment or system and AVN uses the US regulations standard review plan (SRP) as a reference for technical reviews. The Federal Agency for Nuclear Control (FANC) is responsible for the surveillance of all nuclear activities in Belgium, but the private non-profit authorised inspection organisation (AVN) does perform inspections and other regulatory tasks delegated by FANC. Controls of electrical components and systems with regard to the general Belgian electrical regulations are performed by accredited inspection organisations. The regulatory framework for the safety of nuclear activities in Finland is domestic and detailed safety requirements are provided by the Radiation and Nuclear Safety Authority (STUK). They cover specific requirements for the licensing procedure for electrical and IandC equipment. In Finland, there are no general differences in the licensing procedure for electrical, instrumentation, and mechanical equipment and the licensing procedure is basically the same for all types of systems, structures and equipment. STUK has the responsibility for the regulatory control in Finland and may seek

    In published studies, it has been suggested that dental wear is associated with gastroesophageal reflux disease (GERD). This systematic review was carried out to evaluate the association of GERD, dental erosion, and halitosis and to compare the indices adopted in epidemiological surveys. The Medline database (until October, 2011) was searched systematically to identify studies evaluating the prevalence of oral alterations, such as dental erosion and halitosis, in patients with GERD symptoms. Two reviewers analyzed all reports and the selected studies were evaluated according to the quality of evidence, using the validated Newcastle-Ottawa Quality Assessment Scale. Full-text copies of a total of 32 publications were obtained in duplicate. Sixteen publications were identified among the citations in the Bibliographic lists of studies that fulfilled the exclusion/inclusion criteria and quality of evidence. The relationship between dental erosion and GERD patients was significant in only seven studies. According to three studies, halitosis could be one of several extraesophageal symptoms or manifestations in GERD patients. In one study, it was found that the mucosa of GERD patients was significantly more acidic in comparison with that of the control group. This systematic review showed that there is a relationship between GERD and oral diseases (dental erosion and halitosis). The epidemiological surveys used different indices to analyze GERD and dental erosion. Further research could investigate the best method for assessing the two diseases.

    Novak, Josef; Kohoutková, Alena; Křístek, Vladimír; Vodička, Jan

    2017-09-01

    Long-term traffic restrictions belong to the key disadvantages of conventional cast-in-plane concrete pavements which have been used for technical structures such as roads, parking place and airfield pavements. As a consequence, the pressure is put on the development of such systems which have short construction time, low production costs, long-term durability, low maintenance requirements etc.. The paper presents the first step in the development of an entirely new precast concrete pavement (PCP) system applicable to airfield and highway pavements. The main objective of the review of PCP systems is to acquire a better understanding of the current systems and design methods used for transport infrastructure. There is lack of information on using PCP systems for the construction of entirely new pavements. To most extensive experience is dated back to the 20th century when hexagonal slab panels and system PAG were used in the Soviet Union for the military airfields. Since cast-in-situ pavements became more common, the systems based on precast concrete panels have been mainly utilized for the removal of damaged sections of existing structures including roads, highways etc.. Namely, it concerns Fort Miller Super Slab system, Michigan system, Uretek Stitch system and Kwik system. The presented review indicates several issues associated with the listed PCP systems and their applications to the repair and rehabilitation of existing structures. Among others, the type of manufacturing technology, particularly the position of slots for dowel bars, affects the durability and performance of the systems. Gathered information serve for the development of a new system for airfield and highway pavement construction.

    Accidents attributable to in-flight loss of control are the primary cause for fatal commercial jet accidents worldwide. The National Aeronautics and Space Administration (NASA) conducted a literature review to determine and identify the quantitative standards for assessing upset recovery performance. This review contains current recovery procedures for both military and commercial aviation and includes the metrics researchers use to assess aircraft recovery performance. Metrics include time to first input, recognition time and recovery time and whether that input was correct or incorrect. Other metrics included are: the state of the autopilot and autothrottle, control wheel/sidestick movement resulting in pitch and roll, and inputs to the throttle and rudder. In addition, airplane state measures, such as roll reversals, altitude loss/gain, maximum vertical speed, maximum/minimum air speed, maximum bank angle and maximum g loading are reviewed as well.

    National and subnational level surveys are important for monitoring disease burden, prioritizing resource allocation, and evaluating public health policies. As mobile phone access and ownership become more common globally, mobile phone surveys (MPSs) offer an opportunity to supplement traditional public health household surveys. The objective of this study was to systematically review the current landscape of MPSs to collect population-level estimates in low- and middle-income countries (LMICs). Primary and gray literature from 7 online databases were systematically searched for studies that deployed MPSs to collect population-level estimates. Titles and abstracts were screened on primary inclusion and exclusion criteria by two research assistants. Articles that met primary screening requirements were read in full and screened for secondary eligibility criteria. Articles included in review were grouped into the following three categories by their survey modality: (1) interactive voice response (IVR), (2) short message service (SMS), and (3) human operator or computer-assisted telephone interviews (CATI). Data were abstracted by two research assistants. The conduct and reporting of the review conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 6625 articles were identified through the literature review. Overall, 11 articles were identified that contained 19 MPS (CATI, IVR, or SMS) surveys to collect population-level estimates across a range of topics. MPSs were used in Latin America (n=8), the Middle East (n=1), South Asia (n=2), and sub-Saharan Africa (n=8). Nine articles presented results for 10 CATI surveys (10/19, 53%). Two articles discussed the findings of 6 IVR surveys (6/19, 32%). Three SMS surveys were identified from 2 articles (3/19, 16%). Approximately 63% (12/19) of MPS were delivered to mobile phone numbers collected from previously administered household surveys. The majority of MPS (11

    Wyatt, Gillian; Grey, Nick; Deery, Chris

    2004-09-01

    The aim of this study was to conduct a survey of surgical crown lengthening practice performed by dental specialists and general dental practitioners using a cross-sectional questionnaire. One hundred general dental practitioners and 100 specialists from each of the following specialties: prosthodontics, periodontics, restorative dentistry and surgical dentistry. There were fewer surgical dentists performing surgical crown lengthening than the other specialists. The specialists in periodontics were significantly more likely to perform surgical crown lengthening than not. The respondents predominantly considered that periodontal surgical crown lengthening is within the remit of periodontics. 33% of the respondents performing more than 50 PSCL procedures in one year thought that the gingival margin was stable after three months. 33% thought that it was stable after six months and 33% declined to state a post-operative marginal stability time period.

    2016-07-11

    The Internet of Things (IoT) has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT) term.

    The Mevva (metal vapor vacuum arc) ion source provides high current beams of multiply-charged metal ions suitable for use in heavy ion synchrotrons as well as for metallurgical ion implantation. Pulsed beam currents of up to several amperes can be produced at ion energies of up to several hundred keV. Operation has been demonstrate for 48 metallic ion species: Li, C, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, Sr, Y, Zr, Nb, Mo, Pd, Ag, Cd, In, Sn, Ba, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho, Er, Yb, Hf, Ta, W, Ir, Pt, Au, Pb, Bi, Th and U. When the source is operated optimally the rms fractional beam noise can be as low as 7% of the mean beam current; and when properly triggered the source operates reliably and reproducibly for many tens of thousands of pulses without failure. In this paper we review the source performance referred specifically to its use for synchrotron injection. 15 refs., 3 figs.

    Systematic reviews are fundamental decision-making tools for the assessment of the effectiveness of healthcare interventions and for determining future research fields. In the field of hand surgery, so far, there exists only a limited number of systematic reviews. According to the diversity and multitude of hand surgical topics, relevant fields for systematic reviews were identified by means of an expert ranking. A catalogue of 24 topics was extracted from publications of representative hand surgical journals. These topics were categorized and integrated into a questionnaire which was presented to 30 experts in the field of hand surgery. Every single topic had to be rated by marks from 1 (very relevant) to 5 (not relevant). Further topics could have been indicated. Averaging of the marks allowed to define a ranking and a prioritisation of the topics. 29 of 30 questionnaires were returned. The ranking showed scapholunate ligament injury, Kienboeck's disease and scaphoid nonunion to have the highest relevance, followed by 5 other topics dealing with wrist problems. The lowest relevance was attributed to neck fractures of the fifth metacarpal, ulnar collateral ligament injury of the thumb metacarpophalangeal joint and postoperative management following replantation. The results of the presented survey allow for a prioritisation of topics for systematic reviews in hand surgery. The ranking of the topics emphasises the particular relevance of injuries and diseases of the wrist. © Georg Thieme Verlag KG Stuttgart · New York.

    A performance audit of the U.S. Geological Survey (USGS), Energy Resource Program (ERP) Inorganic Geochemistry Laboratory (IGL) was conducted between August, 2003 and October, 2005. The goals were to ensure that a high level of analytical performance was maintained and identify any areas that could be enhanced. The audit was subdivided into three phases. Phase 1 was a preliminary assessment of current performance based on recent performance on CANSPEX samples. IGL performance was also compared to laboratories world-wide with similar scope. Phase 2 consisted of the implementation of the recommended changes made in Phase 1. Phase 3 of the audit consisted of a reassessment effort to evaluate the effectiveness of the recommendations made in the Phase 1 and an on-site audit of the laboratory facilities. Phases 1 and 3 required summary reports that are included in Appendices A and B of this report. The audit found that the IGL was one of the top two laboratories compared for trace element analyses. Several recommendations to enhance performance on major and minor elemental parameters were made and implemented. Demonstrated performance improvements as a result of the recommended changes were documented. Several initiatives to sustain the performance improvements gained from the audit have been implemented.

    Full Text Available Objective: 1 To evaluate the participation rate and identify the practical barriers to implementing a community pharmacist-led medication review service in francophone Switzerland and, 2 To assess the effectiveness of external support.Methods: A qualitative survey was undertaken to identify barriers to patient inclusion and medication review delivery in daily practice among all contactable independent pharmacists working in francophone Switzerland (n=78 who were members of a virtual chain (pharmacieplus, regardless of their participation in a simultaneous cross-sectional study. This study analyzed the dissemination of a medication review service including a prescription and drug utilization review with access to clinical data, a patient interview and a pharmaceutical report to the physicians. In addition, we observed an exploratory and external coaching for pharmacists that we launched seven months after the beginning of the cross-sectional study. Results: Poor motivation on the part of pharmacists and difficulties communicating with physicians and patients were the primary obstacles identified. Lack of time and lack of self-confidence in administering the medication review process were the most commonly perceived practical barriers to the implementation of the new service. The main facilitators to overcome these issues may be well-planned workflow organization techniques, strengthened by an adequate remuneration scheme and a comprehensive and practice-based training course that includes skill-building in pharmacotherapy and communication. External support may partially compensate for a weak organizational framework.Conclusions: To facilitate the implementation of a medication review service, a strong local networking with physicians, an effective workflow management and a practice- and communications-focused training for pharmacists and their teams seem key elements required. External support can be useful to help some pharmacists improve their

    Full Text Available Introduction: In the last several decades, South Korea has rapidly adopted Western customs and practices. Yet, cultural differences between South Korea and the United States exist. The purpose ofthis study was to identify and characterize potential cultural differences in the Korean and US institutional review board (IRB approach to certain topics.Methods: A qualitative analysis of a 9-item survey, describing 4 research study case scenarios, sent to IRB members from the United States and South Korea. The case scenarios involved the followingissues: (1 the need for consent for retrospective chart review when research subjects receive their care after the study is conceived; (2 child assent; (3 individual versus population benefit; and (4 exception from informed consent in emergency resuscitation research. The free-text responses were analyzed and abstracted for recurrent themes.Results: Twenty-three of the 45 survey recipients completed the survey, for an overall response rate of 51%. The themes that emerged were as follows: (1 the importance of parental authority among Korean participants versus the importance of child autonomy and child assent among US participants; (2 the recognition of the rights of a proxy or surrogate who can represent an individual’s values by all participants; and (3 the importance of the community, expressed by the Korean respondents, versus individualism, expressed by US respondents.Conclusion: Whereas US participants appear to emphasize the importance of the individual and the autonomy of a child, the Korean respondents stressed the importance of parental authority andbenefiting the community, above and beyond that of the individual person. However, there was substantial overlap in the themes expressed by respondents from both countries.

    Chinese biomedical databases contain a large number of publications available to systematic reviewers, but it is unclear whether they are used for synthesizing the available evidence. We report a case of two systematic reviews on the accuracy of anti-cyclic citrullinated peptide for diagnosing rheumatoid arthritis. In one of these, the authors did not search Chinese databases; in the other, they did. We additionally assessed the extent to which Cochrane reviewers have searched Chinese databases in a systematic overview of the Cochrane Library (inception to 2014). The two diagnostic reviews included a total of 269 unique studies, but only 4 studies were included in both reviews. The first review included five studies published in the Chinese language (out of 151) while the second included 114 (out of 118). The summary accuracy estimates from the two reviews were comparable. Only 243 of the published 8,680 Cochrane reviews (less than 3%) searched one or more of the five major Chinese databases. These Chinese databases index about 2,500 journals, of which less than 6% are also indexed in MEDLINE. All 243 Cochrane reviews evaluated an intervention, 179 (74%) had at least one author with a Chinese affiliation; 118 (49%) addressed a topic in complementary or alternative medicine. Although searching Chinese databases may lead to the identification of a large amount of additional clinical evidence, Cochrane reviewers have rarely included them in their search strategy. We encourage future initiatives to evaluate more systematically the relevance of searching Chinese databases, as well as collaborative efforts to allow better incorporation of Chinese resources in systematic reviews.

    Full Text Available Abstract Background Performance of specialty referrals is coming under scrutiny, but a lack of identifiable measures impedes measurement efforts. The objective of this study was to systematically review the literature to identify published measures that assess specialty referrals. Methods We performed a systematic review of the literature for measures of specialty referral. Searches were made of MEDLINE and HealthSTAR databases, references of eligible papers, and citations provided by content experts. Measures were eligible if they were published from January 1973 to June 2009, reported on validity and/or reliability of the measure, and were applicable to Organization for Economic Cooperation and Development healthcare systems. We classified measures according to a conceptual framework, which underwent content validation with an expert panel. Results We identified 2,964 potentially eligible papers. After abstract and full-text review, we selected 214 papers containing 244 measures. Most measures were applied in adults (57%, assessed structural elements of the referral process (60%, and collected data via survey (62%. Measures were classified into non-mutually exclusive domains: need for specialty care (N = 14, referral initiation (N = 73, entry into specialty care (N = 53, coordination (N = 60, referral type (N = 3, clinical tasks (N = 19, resource use (N = 13, quality (N = 57, and outcomes (N = 9. Conclusions Published measures are available to assess the specialty referral process, although some domains are limited. Because many of these measures have been not been extensively validated in general populations, assess limited aspects of the referral process, and require new data collection, their applicability and preference in assessment of the specialty referral process is needed.

    Pleural fluid aspiration is a routine procedure for pulmonologists and internists. Our aim was to evaluate technical and methodological aspects of diagnostic and therapeutic thoracenteses performed by last two-year residents of Pulmonology and Internal Medicine. An online 24-item questionnaire was sent to participants, and responses were evaluated according to the medical specialty. The survey was completed by 139 (17.1%) residents (71 internists and 68 pulmonologists). 29.5% and 41% performed one or no diagnostic or therapeutic thoracenteses monthly, respectively. Only 44% used ultrasonography to guide pleural procedures. Less than half of respondents used local anesthesia for diagnostic aspirations. Contrary to current recommendations, 25% of residents employed intramuscular needles for therapeutic aspirations. More than 80% of residents routinely ordered pleural fluid cultures and cytological studies, regardless of the clinical suspicion. About 40% requested imaging studies after a diagnostic thoracentesis. Half or more of the respondents were unaware of pH measurement methodologies, culture type for mycobacteria, and performance of cell blocks. Pulmonologists were more experienced than internists, and also made use of ultrasonography more frequently. This survey highlights gaps of knowledge and skills in conducting diagnostic and therapeutic thoracenteses. Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

    2016-04-01

    Government and health organisations worldwide have recently reviewed the evidence on the role of dietary sugars in relation to health outcomes. Hence, it is timely to review current intakes of dietary sugars with respect to this guidance and as a benchmark for future surveillance. This review collates data from nationally representative dietary surveys across the world and reports estimates of intakes of total and added sugars, and sucrose in different population subgroups. Total sugars includes all mono- and disaccharides; namely, glucose, fructose, lactose, sucrose and maltose. Added and free sugars differ in the quantity of natural sugars included in their definitions. Free sugars include sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates, whereas added sugars typically only refer to those added during processing. Most countries reported intakes of total sugars, with fewer reporting intakes of added sugars and sucrose. No country reported intakes of free sugars. The available data suggest that total sugars as a percentage of energy were highest in the infant (sugars were higher in school-aged children and adolescents (up to 19% of total energy) compared to younger children or adults. Further research into the dietary patterns contributing to added sugars intake in children and adolescents is warranted. It would also be beneficial to policy guidance if future dietary surveys employed a uniform way of expressing sugars that is feasible to measure and has public health significance. © 2015 The Authors.

    Postal surveys are becoming an increasingly popular method of conducting research in Malaysia. However, the response rates from these surveys have not been well studied. All postal surveys published in the Medical Journal of Malaysia between 1991-2000 were therefore reviewed to provide an overview of the response rates that may be expected, and to assess if this is a valid method of conducting research here. The response rates of postal surveys ranged from 30-87.5%. Seven of 13 postal surveys (54%) had a response rate of less than 50% and only 2 of 13 (15.4%) had a response rate of more than 70%, raising doubts on the use of postal surveys as a research tool.

    An important goal for national and large-scale surveys of user experiences is quality improvement. However, large-scale surveys are normally conducted by a professional external surveyor, creating an institutionalized division between the measurement of user experiences and the quality work that is performed locally. The aim of this study was to identify and describe scientific studies related to the use of national and large-scale surveys of user experiences in local quality work. Ovid EMBASE, Ovid MEDLINE, Ovid PsycINFO and the Cochrane Database of Systematic Reviews. Scientific publications about user experiences and satisfaction about the extent to which data from national and other large-scale user experience surveys are used for local quality work in the health services. Themes of interest were identified and a narrative analysis was undertaken. Thirteen publications were included, all differed substantially in several characteristics. The results show that large-scale surveys of user experiences are used in local quality work. The types of follow-up activity varied considerably from conducting a follow-up analysis of user experience survey data to information sharing and more-systematic efforts to use the data as a basis for improving the quality of care. This review shows that large-scale surveys of user experiences are used in local quality work. However, there is a need for more, better and standardized research in this field. The considerable variation in follow-up activities points to the need for systematic guidance on how to use data in local quality work. © The Author 2014.

    Directory of Open Access Journals (Sweden)

    Santos-Vijande, M. L.

    2007-01-01

    Full Text Available The purpose of this article is to develop an instrument for measuring TQM implementation following the European Foundation for Quality Management Excellence Model and to provide empirical evidence on the relationship between management practices and measures of business performance in the model. To this end, the study employs survey data collected from Spanish manufacturing and service firms. Confirmatory factor analysis is used to test the psychometric properties of the measurement scales and the hypothesized relationships between total quality management practices and organizational performance are examined using structural equation modeling. The findings of the research indicate that the adoption of the TQM practices suggested in the EFQM Excellence Model allows firms to outperform their competitors in the results criteria included in the Model. Therefore, this paper provides a valuable benchmarking data for firms as it substantiates the EFQM Enabler’s contribution to the attainment of competitive advantage.

    Evaluation of emergency department (ED) performance remains a difficult task due to the lack of consensus on performance measures that reflects high quality, efficiency, and sustainability. To describe, map, and critically evaluate which performance measures that the published literature regard as being most relevant in assessing overall ED performance. Following the PRISMA guidelines, a systematic literature review of review articles reporting accentuated ED performance measures was conducted in the databases of PubMed, Cochrane Library, and Web of Science. Study eligibility criteria includes: 1) the main purpose was to discuss, analyse, or promote performance measures best reflecting ED performance, 2) the article was a review article, and 3) the article reported macro-level performance measures, thus reflecting an overall departmental performance level. A number of articles addresses this study's objective (n = 14 of 46 unique hits). Time intervals and patient-related measures were dominant in the identified performance measures in review articles from US, UK, Sweden and Canada. Length of stay (LOS), time between patient arrival to initial clinical assessment, and time between patient arrivals to admission were highlighted by the majority of articles. Concurrently, "patients left without being seen" (LWBS), unplanned re-attendance within a maximum of 72 hours, mortality/morbidity, and number of unintended incidents were the most highlighted performance measures that related directly to the patient. Performance measures related to employees were only stated in two of the 14 included articles. A total of 55 ED performance measures were identified. ED time intervals were the most recommended performance measures followed by patient centeredness and safety performance measures. ED employee related performance measures were rarely mentioned in the investigated literature. The study's results allow for advancement towards improved performance measurement and

    An efficient resource allocation is a fundamental requirement in high performance computing (HPC) systems. Many projects are dedicated to large-scale distributed computing systems that have designed and developed resource allocation mechanisms with a variety of architectures and services. In our study, through analysis, a comprehensive survey for describing resource allocation in various HPCs is reported. The aim of the work is to aggregate under a joint framework, the existing solutions for HPC to provide a thorough analysis and characteristics of the resource management and allocation strategies. Resource allocation mechanisms and strategies play a vital role towards the performance improvement of all the HPCs classifications. Therefore, a comprehensive discussion of widely used resource allocation strategies deployed in HPC environment is required, which is one of the motivations of this survey. Moreover, we have classified the HPC systems into three broad categories, namely: (a) cluster, (b) grid, and (c) cloud systems and define the characteristics of each class by extracting sets of common attributes. All of the aforementioned systems are cataloged into pure software and hybrid/hardware solutions. The system classification is used to identify approaches followed by the implementation of existing resource allocation strategies that are widely presented in the literature.

    2014-01-01

    Modern datacenter servers hosting popular Internet services face significant and multi-facet challenges in performance and power control. The user-perceived performance is the result of a complex interaction of complex workloads in a very complex underlying system. Highly dynamic and bursty workloads of Internet services fluctuate over multiple time scales, which has a significant impact on processing and power demands of datacenter servers. High-density servers apply virtualization technology for capacity planning and system manageability. Such virtualized computer systems are increasingly large and complex. This paper surveys representative approaches to autonomic performance and power control on virtualized servers, which control the quality of service provided by virtualized resources, improve the energy efficiency of the underlying system, and reduce the burden of complex system management from human operators. It then presents three designed self-adaptive resource management techniques based on machine learning and control for percentile-based response time assurance, non-intrusive energy-efficient performance isolation, and joint performance and power guarantee on virtualized servers. The techniques were implemented and evaluated in a testbed of virtualized servers hosting benchmark applications. Finally, two research trends are identified and discussed for sustainable cloud computing in green datacenters.

    Full Text Available Abstract Background Comprehensive, multi-level approaches are required to address obesity. One important target for intervention is the economic domain. The purpose of this study was to synthesize existing evidence regarding the impact of economic policies targeting obesity and its causal behaviours (diet, physical activity, and to make specific recommendations for the Canadian context. Methods Arksey and O'Malley's (2005 methodological framework for conducting scoping reviews was adopted for this study and this consisted of two phases: 1 a structured literature search and review, and 2 consultation with experts in the research field through a Delphi survey and an in-person expert panel meeting in April 2010. Results Two key findings from the scoping review included 1 consistent evidence that weight outcomes are responsive to food and beverage prices. The debate on the use of food taxes and subsidies to address obesity should now shift to how best to address practical issues in designing such policies; and 2 very few studies have examined the impact of economic instruments to promote physical activity and clear policy recommendations cannot be made at this time. Delphi survey findings emphasised the relatively modest impact any specific economic instrument would have on obesity independently. Based on empirical evidence and expert opinion, three recommendations were supported. First, to create and implement an effective health filter to review new and current agricultural polices to reduce the possibility that such policies have a deleterious impact on population rates of obesity. Second, to implement a caloric sweetened beverage tax. Third, to examine how to implement fruit and vegetable subsidies targeted at children and low income households. Conclusions In terms of economic interventions, shifting from empirical evidence to policy recommendation remains challenging. Overall, the evidence is not sufficiently strong to provide clear policy

  1. Database Survey of Anti-Inflammatory Plants in South America: A Review

    2011-04-01

    Full Text Available Inflammation is a complex event linked to tissue damage whether by bacteria, physical trauma, chemical, heat or any other phenomenon. This physiological response is coordinated largely by a variety of chemical mediators that are released from the epithelium, the immunocytes and nerves of the lamina propria. However, if the factor that triggers the inflammation persists, the inflammation can become relentless, leading to an intensification of the lesion. The present work is a literature survey of plant extracts from the South American continent that have been reported to show anti-inflammatory activity. This review refers to 63 bacterial families of which the following stood out: Asteraceae, Fabaceae, Euphorbiaceae, Apocynaceae and Celastraceae, with their countries, parts used, types of extract used, model bioassays, organisms tested and their activity.

    2006-01-01

    Mental health diversion is a process where alternatives to criminal sanctions are made available to persons with mental illness (PMI) who have come into contact with the law. One form of mental health diversion is pre-arrest, in which the police use their discretion in laying charges. Concomitant with the growth of pre-arrest diversion programs is a growing body of research devoted to the phenomenon. The purpose of this paper is to review the existing literature of pre-arrest diversion, and to report the results of an international survey of pre-arrest diversion programs we conducted to identify evidence-based practices. On the basis of our review and survey, we note that successful pre-trial programs appear to integrate relevant mental health, substance abuse and criminal justice agencies by having regular meetings between key personnel from the various agencies. Often, a liaison person with a mandate to effect strong leadership plays a key role in the coordination of various agencies. Streamlining services through the creation of an emergency drop-off center with a no-refusal policy for police cases is seen as crucial. While there is some indication that mentally ill offenders benefit from their participation in this form of diversion, the evaluative literature has not yet achieved the "critical mass" necessary to create generalizable, evidence-based knowledge. The absence of generally agreed-upon outcomes could lead to the inequitable application of basic principles of diversion. We suggest that indicators, benchmarks, and outcomes must be agreed upon if a comprehensive understanding of pre-arrest programs is to emerge.

    2010-01-15

    Background: Computed tomographic colonography (CTC) has gained increased acceptance in the last few years as a valid substitute for double-contrast barium enema (DCBE). However, implementation of new technologies is complex, since several factors may influence the process. Purpose: To evaluate the current situation in Sweden concerning implementation of CTC, as compared to a previous national survey in 2005. Material and Methods: In December 2008, a structured, self-assessed questionnaire regarding implementation and technical performance of CTC was mailed to all radiology departments in Sweden. In March 2009, departments who had not replied were contacted by e-mail or by telephone. All (100%, 119/119) departments answered the questionnaire. Results: CTC is currently performed in 50/119 (42%) departments, i.e., 18 additional departments compared to 2005. Twenty-three out of 60 (38%) responding departments stated that they intend to start to perform CTC in the near future. DCBE is currently performed in 77/119 (65%) departments, 12 departments less compared to 2005. The most common reasons for non-implementation of CTC are non-availability of spiral CT scanner (41%, 26/64) and/or multidetector-row CT scanner (39%, 25/64), and lack of doctors' time (34%, 22/64). Only 3% (2/64) of departments are 'awaiting further scientific documentation' on CTC, a significant reduction compared to 2005 (P=0.002). Until 2009, 59% (29/49) of CTC centers had performed more than 200 CTCs compared to 13% (4/32) of CTC centers in 2005. Intravenous contrast material is routinely administered in 86% (42/49), and carbon dioxide is used to distend the colon in 90% (44/49). Almost all radiology departments (93%, 93/100) currently believe that CTC will 'absolutely' or 'probably' replace barium enema in the future, while in 2005 only 56% (55/99) gave similar answers. Conclusion: The survey reflects a further transition process from DCBE to CTC, with attitudes

  7. A Relationship Framework for Building Information Modeling (BIM Capability in Quantity Surveying Practice and Project Performance

    Full Text Available Construction industry has suffered from poor project performance and it’s crucial to find out solution to improve this issue. Quantity surveyors (QSs play a key role in managing project cost. However, their method of performing tasks is tedious till affect the project performance. Building information modeling (BIM application is attaining attention in the construction industry as a mean to improve the project performance. However, the adoption is low among QSs due to limited study of the BIM’s capabilities in their profession. This research aims to identify the BIM capabilities in quantity surveying practices and examine its relationship with project performance by developing a relationship framework. Data were collected through questionnaire survey and interview in Malaysia. Questionnaire results revealed that several BIM capabilities were significantly correlated with project performance and they were validated through interview. The relationship framework will guide QSs to focus on the identified BIM capabilities for better project outcomes.La industria de la construcción ha sufrido históricamente desviaciones en las mediciones de los materiales empleados frente a las cantidades proyectadas. Los aparejadores juegan un papel clave en este aspecto como responsables de la recepción de materiales. Sin embargo, el trabajo de medición es tedioso hasta el punto de afectar al rendimiento del proyecto. La aplicación del Building Information Modeling (BIM está logrando mejorar este trabajo. Aun así, su utilización es baja entre los aparejadores debido a la escasa formación recibida sobre las posibilidades del BIM. Esta investigación busca identificar las capacidades del BIM aplicado a la medición de materiales y examinar su relación con el rendimiento del proyecto desarrollando un marco de relación. Mediante encuestas y entrevistas realizadas en Malasia, se obtuvieron datos que revelaron que varias capacidades de BIM se correlacionan

    Decisionmakers and guideline developers demand rapid syntheses of the evidence when time sensitive evidence-informed decisions are required. A potential trade-off of such rapid reviews is that their results can have less reliability than results of systematic reviews that can lead to an increased risk of making incorrect decisions or recommendations. We sought to determine how much incremental uncertainty about the correctness of an answer guideline developers and health policy decisionmakers are willing to accept in exchange for a rapid evidence-synthesis. Employing a purposive sample, we conducted an international web-based, anonymous survey of decisionmakers and guideline developers. Based on a clinical treatment, a public health, and a clinical prevention scenario, participants indicated the maximum risk of getting an incorrect answer from a rapid review that they would be willing to accept. We carefully reviewed data and performed descriptive statistical analyses. In total, 325 (58.5%) of 556 participants completed our survey and were eligible for analysis. The median acceptable incremental risk for getting an incorrect answer from a rapid review across all three scenarios was 10.0% (interquartile range [IQR] 5.0-15.0). Acceptable risks were similar for the clinical treatment (n = 313, median 10.0% [IQR 5.0-15.0]) and the public health scenarios (n = 320, median 10.0% [IQR 5.0-15.0]) and lower for the clinical prevention scenario (n = 312, median 6.5% [IQR 5.0-10.5]). Findings suggest that decisionmakers are willing to accept some trade-off in validity in exchange for a rapid review. Nevertheless, they expect the validity of rapid reviews to come close to that of systematic reviews.

  10. Internet of Things: A Review of Surveys Based on Context Aware Intelligent Services

    Full Text Available The Internet of Things (IoT has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT term.

    Little is known about postoperative opioid prescribing patterns among dermatologic surgeons. To better understand postoperative opioid prescribing patterns among dermatologic surgeons in the United States. Two-part analysis consisting of a retrospective chart review of 233 dermatologic surgery patients at a single institution and an e-mail survey of American Society for Dermatologic Surgery (ASDS) members. (1) Retrospective review: 35% (82/233) of the patients received an opioid prescription. Larger defect size, repair of the defect, perioral and nasal site, and surgeon A or B performing surgery predicted opioid prescription. (2) E-mail survey: 556 ASDS members practicing within the United States responded. Sixty-four percent (357/556) reported prescribing opioids after ≤10% of cases. Surgeons younger than 55 years old, male surgeons, and surgeons in the southern and western United States were more likely to prescribe opioids after >10% of cases. Seventy-six percent (397/520) believed patients used ≤50% of the opioid pills prescribed. The retrospective review suggests that opioid prescribing is predicted by characteristics of the surgery (i.e., size, defect repair type, and anatomic location) and characteristics of the surgeon (i.e., age, sex, and practice location) with significant heterogeneity in prescribing habits. The national survey results raise the possibility that patients might not take all prescribed opioid pills after dermatologic surgery. Further investigation is warranted to determine how patients are actually using prescription pain pills to balance pain control with patient safety.

    Little is known about how real-time online rating platforms such as Yelp may complement the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, which is the US standard for evaluating patients' experiences after hospitalization. We compared the content of Yelp narrative reviews of hospitals to the topics in the HCAHPS survey, called domains in HCAHPS terminology. While the domains included in Yelp reviews covered the majority of HCAHPS domains, Yelp reviews covered an additional twelve domains not found in HCAHPS. The majority of Yelp topics that most strongly correlate with positive or negative reviews are not measured or reported by HCAHPS. The large collection of patient- and caregiver-centered experiences found on Yelp can be analyzed with natural language processing methods, identifying for policy makers the measures of hospital quality that matter most to patients and caregivers. The Yelp measures and analysis can also provide actionable feedback for hospitals.

  13. Scientific value of systematic reviews: survey of editors of core clinical journals.

    Synthesizing research evidence using systematic and rigorous methods has become a key feature of evidence-based medicine and knowledge translation. Systematic reviews (SRs) may or may not include a meta-analysis depending on the suitability of available data. They are often being criticised as 'secondary research' and denied the status of original research. Scientific journals play an important role in the publication process. How they appraise a given type of research influences the status of that research in the scientific community. We investigated the attitudes of editors of core clinical journals towards SRs and their value for publication. We identified the 118 journals labelled as "core clinical journals" by the National Library of Medicine, USA in April 2009. The journals' editors were surveyed by email in 2009 and asked whether they considered SRs as original research projects; whether they published SRs; and for which section of the journal they would consider a SR manuscript. The editors of 65 journals (55%) responded. Most respondents considered SRs to be original research (71%) and almost all journals (93%) published SRs. Several editors regarded the use of Cochrane methodology or a meta-analysis as quality criteria; for some respondents these criteria were premises for the consideration of SRs as original research. Journals placed SRs in various sections such as "Review" or "Feature article". Characterization of non-responding journals showed that about two thirds do publish systematic reviews. Currently, the editors of most core clinical journals consider SRs original research. Our findings are limited by a non-responder rate of 45%. Individual comments suggest that this is a grey area and attitudes differ widely. A debate about the definition of 'original research' in the context of SRs is warranted.

  5. LITERATURE REVIEW ON CORPORATE GOVERNANCE - FIRM PERFORMANCE RELATIONSHIP

    Directory of Open Access Journals (Sweden)

    Pintea Mirela-Oana

    2015-07-01

    Full Text Available In the matter of corporate governance reforms, an important aspect is whether the implementation of corporate governance principles and codes has a positive impact on firm performance. The literature testing the relationship between different corporate governance mechanisms and firm performance is extensive. Over time, a lot of corporate governances mechanisms were studied in relation to firm performance and the most used are: CEO duality, board size, proportion of non- executive directors, board committees, ownership structure and concentration, managers’ compensation and incentives schemes. With time, different authors began to use more comprehensive measures for corporate governance rather than a single variable or a single governance mechanism, the so called corporate governance indexes. Regarding performance there are three main approaches to firm performance in social science research: research based on market prices, accounting ratios and total factor profitability.The most used performance measures are: Tobin’s Q, return on equity, return on asset and economic value added. In our paper, we present the studies undertaken since the 1990’s regarding the relationship between different mechanisms of corporate governance and firm performance and between corporate governance index and performance for both developed and developing countries around the world. Regarding the working tools used in this theoretical research we can mention the longitudinal method, by presenting the evolution in time of empirical studies on the research topic and the comparative method used in presenting the resulys of different studies mentioned in our paper. The results of the studies are inconclusive, some studies founded a strog positive relation, others founded a negative correlation between corporate governance and firm performance, while a third category of studies didn’t found any relationship at all. We used participative observation method by issuing

    Home visits have been shown to improve quality of care, save money, and improve outcomes. Primary care physicians are in an ideal position to provide these visits; of note, the Accreditation Council for Graduate Medical Education no longer requires home visits as a component of family medicine residency training. To investigate changes in home visit numbers and expectations, attitudes, and approaches to training among family medicine residency program directors. This research used the Council of Academic Family Medicine Educational Research Alliance (CERA) national survey of family medicine program directors in 2015. Questions addressed home visit practices, teaching and evaluation methods, common types of patient and visit categories, and barriers. There were 252 responses from 455 possible respondents, representing a response rate of 55%. At most programs, residents performed 2 to 5 home visits by graduation in both 2014 (69% of programs, 174 of 252) and 2015 (68%, 172 of 252). The vast majority (68%, 172 of 252) of program directors expect less than one-third of their graduates to provide home visits after graduation. Scheduling difficulties, lack of faculty time, and lack of resident time were the top 3 barriers to residents performing home visits. There appeared to be no decline in resident-performed home visits in family medicine residencies 1 year after they were no longer required. Family medicine program directors may recognize the value of home visits despite a lack of few formal curricula.

    A national audit of mammography equipment performance, image quality and dose has been conducted in Croatia. Film-processing parameters, optical density (OD), average glandular dose (AGD) to the standard breast, viewing conditions and image quality were examined using TOR(MAM) test object. Average film gradient ranged from 2.6 to 3.7, with a mean of 3.1. Tube voltage used for imaging of the standard 45 mm polymethylmethacrylate phantom ranged from 24 to 34 kV, and OD ranged from 0.75 to 1.94 with a mean of 1.26. AGD to the standard breast ranged from 0.4 to 2.3 mGy with a mean of 1.1 mGy. Besides clinical conditions, the authors have imaged the standard phantom in the referent conditions with 28 kV and OD as close as possible to 1.5. Then, AGD ranged from 0.5 to 2.6 mGy with a mean of 1.3 mGy. Image viewing conditions were generally unsatisfying with ambient light up to 500 lx and most of the viewing boxes with luminance between 1000 and 2000 cd per m(2). TOR(MAM) scoring of images taken in clinical and referent conditions was done by local radiologists in local image viewing conditions and by the referent radiologist in good image viewing conditions. Importance of OD and image viewing conditions for diagnostic information were analysed. The survey showed that the main problem in Croatia is the lack of written quality assurance/quality control (QA/QC) procedures. Consequently, equipment performance, image quality and dose are unstable and activities to improve image quality or to reduce the dose are not evidence-based. This survey also had an educational purpose, introducing in Croatia the QC based on European Commission Guidelines.

    The documentation of treatments used for Juvenile Rheumatoid Arthritis (JRA) is important to allow for the evaluation of practice patterns for future outcome studies. A survey of nine pediatric rheumatologists was performed between September 1999 and February 2000. Each of the physicians prospectively recorded demographic and treatment information on consecutively sampled JRA patients (n=395). Pauciarticular onset JRA was present in 46%, polyarticular onset JRA in 35%, and systemic onset JRA in 19% of the children. Naproxen was the most frequently prescribed medication (55% of the patients), followed by methotrexate (MTX), which was used in 39% of the patients. Folic acid supplementation (1 mg/day) was provided to 69% of the patients treated with MTX. Etanercept was used in 11% of the children. Eleven percent of the patients received corticosteroids, and 13% of children on corticosteroids took calcium supplements. Uveitis was present in 8% and had a chronic course in 79% of those cases. Although systemic medications were used in 50% of the children with uveitis to control eye inflammation, severe damage to the eyes developed in 30% of them. Fourteen percent of the patients required gastroprotective medications. Compared with findings of a similar survey performed in 1993, there was no significant change in the frequency of use of naproxen, but nabumetone is now more often prescribed, and COX-2 inhibitors have been introduced in the therapy of JRA. Changes among second-line agents used for JRA have also occurred, although there was no change in the frequency of use of MTX or corticosteroids. JRA continues to be a treatment challenge for the practicing pediatric rheumatologist. Patients often show incomplete response to the currently available medications. Therefore, new therapeutic agents need to be evaluated for their use in JRA, and the treatment of JRA associated uveitis especially needs to be improved.

    Changes in the delivery of health care have increased the demand for minor surgical and screening procedures in general practice. This has increased the risk of cross-infection with blood-borne viruses and the demand for sterile instruments. The aim of this study was to investigate the knowledge and training of medical personnel in England and Wales on aspects of autoclave use, and to test the effectiveness of their practice autoclaves. An anonymous postal questionnaire and autoclave performance survey using biological indicators was made of 700 general medical practitioners selected at random from FHSA lists from 12 Health Authorities in England and Wales. The overall response rate was 53.1% (N= 372) comprising 10% general practitioners and 90% practice nurses. Eighty-two percent of respondents used autoclaves with a mean age of 2.5 years, of which 91% had been serviced in the past year. While 35% of respondents made daily observation of gauges, 19% did not routinely monitor autoclave effectiveness. Six autoclaves failed to sterilize the spore test ampoules. Fourteen percent of respondents did not autoclave instruments after every patient. Only 33.1% reported wearing gloves during minor operations. Fifty five percent had training in cross-infection prevention. It was concluded that although there has been improvement in instrument decontamination procedures in general practice compared with previous surveys, further education of medical practitioners and practice nurses in the use of autoclaves and infection prevention and control is indicated. The failure of 2% of the autoclaves to kill spores suggests the need for increased monitoring of autoclave performance. Two-thirds of practitioners exposed themselves to increased risk of infection by carrying out minor surgery without the protection of gloves. Copyright 2001 The Hospital Infection Society.

    2013-04-01

    The aim of this article is to identify factors affecting access to breast cancer screening in Mexico according to the sociodemographic characteristics of the women, using three nationally-representative surveys. Descriptive statistics were performed and multiple classification analysis techniques were used. The dependent variables were that the women had realized: 1) breast self-examination, 2) clinical breast examination, or 3) mammography; the covariates were: age group, education level, type of locality (urban/rural), marital status, number of children, enrollment in social security and socioeconomic status. A low level of screening use was detected and gaps were observed between different groups of women according to sociodemographic characteristics. In general women of lower economic strata, without enrollment in social security and with lower educational levels, showed fewer detection practices than the national average.

    Kohan, Lynn; Salajegheh, Reza; Hamill-Ruth, Robin J; Yerra, Sandeep; Butz, John

    2017-01-01

    Background Other than the newly published anticoagulation guidelines, there are currently few recommendations to assist pain medicine physicians in determining the safety parameters to follow when performing interventional pain procedures. Little information exists regarding policies for oral intake, cumulative steroid dose limits, driving restrictions with and without sedation, and routine medication use for interventional procedures. Methods A 16-question survey was developed on common policies currently in use for interventional pain procedures. The questionnaire was distributed through the American Society of Regional Anesthesia and Pain Medicine and American Academy of Pain Medicine. We sought to statistically analyze the range of policies being used by pain medicine physicians and to determine if there are any commonly accepted standards. Results A total of 337 physicians out of 4037 members responded to our survey with a response rate of 8.4%. A total of 82% of these respondents used a sedative agent while performing an interventional pain procedure. The majority of respondents required drivers after procedures, except after trigger points. A total of 47% indicated that they have an nil per os (NPO) policy for procedures without sedation. A total of 98% reported that they had an anticoagulation policy before an interventional procedure. A total of 17% indicated that the interval between steroid doses was <2 weeks, while 53% indicated that they waited 2–4 weeks between steroid doses. Conclusion Our study has clearly demonstrated a wide variation in the current practice among physicians regarding sedation, NPO status, steroid administration, and the need for designated drivers. There was much higher endorsement of policies regarding anticoagulation. There is an obvious need for evidence-based guidelines for these aspects of interventional pain care to improve patient safety and minimize the risk of adverse events. PMID:28360531

    The performance of two light-emitting diode traps with white and black light for capturing phlebotomine sand flies, developed by the Argentinean Leishmaniasis Research Network (REDILA-WL and REDILA-BL traps), were compared with the traditional CDC incandescent light trap. Entomological data were obtained from six sand fly surveys conducted in Argentina in different environments. Data analyses were conducted for the presence and the abundance of Lutzomyia longipalpis, Migonemyia migonei, and Nyssomyia whitmani (106 sites). No differences were found in presence/absence among the three types of traps for all sand fly species (p>0.05). The collection mean of Lu. longipalpis from the REDILA-BL didn´t differ from the CDC trap means, nor were differences seen between the REDILA-WL and the CDC trap collection means (p>0.05), but collections were larger from the REDILA-BL trap compared to the REDILA-WL trap (p0.05). These results suggest that both REDILA traps could be used as an alternative capture tool to the original CDC trap for surveillance of these species, and that the REDILA-BL will also allow a comparable estimation of the abundance of these flies to the CDC light trap captures. In addition, the REDILA-BL has better performance than the REDILA-WL, at least for Lu. longipalpis. © 2015 The Society for Vector Ecology.

    Thermal insulation concrete building plays an important role in environment sustainability especially energy saving buildings. Buildings are one of the largest consumers of energy worldwide. Therefore, significant energy saving can be realized by buildings with proper materials, design and operation. Thermal insulation systems are nowadays mostly applied for such building envelopes where the materials of load bearing structure such as concrete do not have a substantial thermal insulation capability. Thermal insulation in concrete are materials or combinations of materials that are used to provide resistance to heat flow, should have low conductivity for building application in order to represence of a temperature gradient, has an important effect on the heat exchange between the building interior and the ambiance. The aim of this paper is to review the thermal properties include thermal conductivity and specific heat on various types of concrete.

    Science.gov (United States)

    Cayrel, Marc

    1998-08-01

    The four Very Large Telescope secondary mirrors are 1.2-m Beryllium lightweight convex mirrors. REOSC has been selected for the design and manufacturing of the optics and of their supporting system. The first mirror unit has been delivered in September, 1997. Operating from visible to near infrared, the mirror defines the telescope aperture stop and may be chopped during observation. The optical requirements are tight and a high stiffness, low weight and inertia are requested as well. Using beryllium is a technical challenge for such a large optic manufacturing, in particular regarding its stability. The requirements and design are presented, we review the mirror manufacturing steps: blank production, machining, grinding, Nickel plating, polishing, integration and testing. The optical quality control method, a problem for large convex mirrors control, is detailed. The results of acceptance testing of mirror No. 1 are summarized, we present conclusions about the mirror figure stability. The status of the three additional mirrors manufacturing is presented to conclude.

    2015-12-01

    We conducted a survey to assess the perspectives of principal investigators and Institutional Review Board (IRB) members on the impact of the IRB structure on the conduct of research and innovative therapy, defined as a nonstandard treatment intended to enhance the well-being of an individual patient. Although investigators and IRB members agreed that the IRB provides adequate protection to study subjects (97% vs. 100%) and an ethically insightful review (88% vs. 100%), a third of clinical investigators felt that the IRB review process limits clinical innovation, in comparison with only 4% of IRB representatives. Limitations of the current IRB review process were explored. We propose several measures to improve the IRB review process while maintaining the protection of human research subjects, including the use of centralized IRBs, the opening of IRB meetings to investigators, the development of metrics and outcome measures for the IRB, and the promotion of guidelines that distinguish research and innovative therapy. © The Author(s) 2015.

  8. Effective multilevel teaching techniques on attending rounds: a pilot survey and systematic review of the literature.

    Certain, Laura K; Guarino, A J; Greenwald, Jeffrey L

    2011-01-01

    While numerous authors acknowledge the challenge of teaching simultaneously to medical students, interns, and residents, few offer specific advice on how to meet that challenge, and none have studied which techniques are most effective. The purpose of this study was to determine whether multilevel teaching is challenging for attendings, whether trainees feel that teaching on rounds is appropriate to their level, and to define multilevel teaching techniques. We surveyed attendings and trainees on the internal medicine services at two academic medical centers. Attendings were divided about whether teaching to multiple levels posed a challenge. Trainees reported that the teaching they received was usually appropriate to their level of training. The most effective techniques for multilevel teaching were Broadening (asking "what if" questions), Targeting (directing questions at specific team members), and Novelty (teaching newly published information), while the least effective were techniques that taught advanced material unfamiliar to most or all of the team. A systematic literature review yielded no studies that focused on multilevel teaching techniques. This article is the first to define and evaluate specific techniques for multilevel instruction in a medical setting and identifies certain techniques as more effective at engaging multiple levels of learners simultaneously.

    Background Policymakers and regulators in the United States (US) and the European Union (EU) are weighing reforms to their medical device approval and post-market surveillance systems. Data may be available that identify strengths and weakness of the approaches to medical device regulation in these settings. Methods and Findings We performed a systematic review to find empirical studies evaluating medical device regulation in the US or EU. We searched Medline using two nested categories that included medical devices and glossary terms attributable to the US Food and Drug Administration and the EU, following PRISMA guidelines for systematic reviews. We supplemented this search with a review of the US Government Accountability Office online database for reports on US Food and Drug Administration device regulation, consultations with local experts in the field, manual reference mining of selected articles, and Google searches using the same key terms used in the Medline search. We found studies of premarket evaluation and timing (n = 9), studies of device recalls (n = 8), and surveys of device manufacturers (n = 3). These studies provide evidence of quality problems in pre-market submissions in the US, provide conflicting views of device safety based largely on recall data, and relay perceptions of some industry leaders from self-surveys. Conclusions Few studies have quantitatively assessed medical device regulation in either the US or EU. Existing studies of US and EU device approval and post-market evaluation performance suggest that policy reforms are necessary for both systems, including improving classification of devices in the US and promoting transparency and post-market oversight in the EU. Assessment of regulatory performance in both settings is limited by lack of data on post-approval safety outcomes.

    As we delve deeper into the ‘Digital Age’, we witness an explosive growth in the volume, velocity, and variety of the data available on the Internet. For example, in 2012 about 2.5 quintillion bytes of data was created on a daily basis that originated from myriad of sources and applications including mobiledevices, sensors, individual archives, social networks, Internet of Things, enterprises, cameras, software logs, etc. Such ‘Data Explosions’ has led to one of the most challenging research issues of the current Information and Communication Technology era: how to optimally manage (e.g., store, replicated, filter, and the like) such large amount of data and identify new ways to analyze large amounts of data for unlocking information. It is clear that such large data streams cannot be managed by setting up on-premises enterprise database systems as it leads to a large up-front cost in buying and administering the hardware and software systems. Therefore, next generation data management systems must be deployed on cloud. The cloud computing paradigm provides scalable and elastic resources, such as data and services accessible over the Internet Every Cloud Service Provider must assure that data is efficiently processed and distributed in a way that does not compromise end-users’ Quality of Service (QoS) in terms of data availability, data search delay, data analysis delay, and the like. In the aforementioned perspective, data replication is used in the cloud for improving the performance (e.g., read and write delay) of applications that access data. Through replication a data intensive application or system can achieve high availability, better fault tolerance, and data recovery. In this paper, we survey data management and replication approaches (from 2007 to 2011) that are developed by both industrial and research communities. The focus of the survey is to discuss and characterize the existing approaches of data replication and management that tackle the

    1983-01-01

    Problems associated with aircraft operations on wet runways are discussed and major factors which influence tire/runway braking and cornering traction capability are identified including runway characteristics, tire hydroplaning, brake system anomalies, and pilot inputs. Research results from investigations conducted at the Langley Aircraft Landing Loads and Traction Facility and from tests with instrumented ground vehicles and aircraft are summarized to indicate the effects of different aircraft, tire, and runway parameters. Several promising means are described for improving tire/runway water drainage capability, brake system efficiency, and pilot training to help optimize aircraft traction performance on wet runways.

  15. Review: Implications of air pollution effects on athletic performance

    Science.gov (United States)

    Pierson, William E.; Covert, David S.; Koenig, Jane Q.; Namekata, Tsukasa; Kim, Yoon Shin

    Both controlled human studies and observational studies suggest air pollution adversely affects athletic performance during both training and competition. The air pollution dosage during exercise is much higher than during rest because of a higher ventilatory rate and both nasal and oral breathing in the former case. For example, SO 2 which is a highly water soluble gas, is almost entirely absorbed in the upper respiratory tract during nasal breathing. However, with oral pharyngeal breathing, the amount of sulfur dioxide that is absorbed is significantly less, and with exercise and oral pharyngeal breathing a significant decrease in upper airway absorption occurs, resulting in a significantly larger dosage of this pollutant being delivered to the tracheobronchial tree. Recently, several controlled human studies have shown that the combination of exercise and pollutant exposure (SO 2 or O 3) caused a marked bronchoconstriction and reduced ventilatory flow when compared with pollution exposure at rest. In a situation like the Olympic Games where ms and mm often determine success of athletes, air pollution can be an important factor in affecting their performance. This paper examines possible impacts of air pollution on athletic competition.

    Full Text Available Definitions of meta-cognition typically have two components: (1 knowledge about one’s own cognitive functioning; and, (2 control over one’s own cognitive activities. Since Flavell and his colleagues provided the empirical foundation on which to build studies of metacognition and the autonoetic (self knowledge required for effective learning, the intervening years have seen the extensive dissemination of theoretical and empirical research on metacognition, which now encompasses a variety of issues and domains including educational psychology and neuroscience. Nevertheless, the psychological and neural underpinnings of metacognitive predictions and reflections that determine subsequent regulation of task performance remain ill understood. This article provides an outline of metacognition in the science of education with evidence drawn from neuroimaging, psycho-physiological, and psychological literature. We will rigorously explore research that addresses the pivotal role of the prefrontal cortex (PFC in controlling the metacognitive processes that underpin the self-regulated learning (SRL strategies learners employ to regulate task performance. The article delineates what those strategies are, and how the learning environment can facilitate or frustrate strategy use by influencing learners’ self-efficacy.

  17. Review and future perspective of central receiver design and performance

    Concentrating solar power (CSP) technology provides a commercial solar option to the utility-scale electricity market. CSP is unique in its ability to include low-cost thermal storage; thus, it can generate electricity when the sun is not available and dispatch electricity to meet varying load requirements. Within the suite of CSP technologies, the central receiver design represents the state-of-the-art technology, promising low cost, high performance, and dispatchable energy production. Current total capacity of central receiver plants worldwide is about 1.0 gigawatt (electric) with operating plants in Spain and the United States, as well as projects under construction in Asia, the Middle East, and North Africa. Central receiver technology has been under development since the 1950s, and a variety of central receiver designs have been explored. A distinguishing feature is the heat transfer medium. Central receiver designs exist that use dense fluids, gases, and solid particles in this role. Water/steam and molten salt receivers have been adopted in current commercial plants and are often coupled with a steam-Rankine power cycle with an operating temperature of less than 600°C. Many new central receiver concepts, such as the volumetric air, supercritical carbon dioxide (sCO2), solid particle, and liquid-metal receiver designs, are under active research and development (R&D). New designs target operating temperatures generally higher than 700°C-800°C—and even above 1000°C—so that higher-performance power cycles such as the sCO2-Brayton cycle or air-Brayton/steam-Rankine combined cycle can be used to promote greater overall system efficiency. Central receiver thermal storage provides dispatchability unavailable from variable-output renewables such as solar photovoltaic and wind power. Case study analysis of the California grid shows that there is a limit on the amount of non-dispatchable renewable generation that the grid can accommodate, beyond which

    Full Text Available Judicial performance evaluations are a relatively new tool for assessing judges and providing information to voters to help them determine whether to retain judges in contested or retention elections. Arizona implemented its judicial evaluation program about 20 years ago, and since that time, the state has continually strived to improve its process. The result is that today Arizona has one of the most progressive and comprehensive judicial performance evaluation programs in the United States. This article takes a critical look at the strengths and weaknesses of Arizona’s program, keeping in mind two key values that the system seeks to protect: judicial accountability and judicial independence. Las evaluaciones del rendimiento judicial son una herramienta relativamente nueva para evaluar a los jueces y ofrecer información a los votantes, que les ayude a decidir si quieren reelegir a los jueces en las elecciones. Arizona implementó su programa de evaluación judicial hace unos 20 años, y desde ese momento, el Estado se ha esforzado continuamente en mejorar el proceso. El resultado es que hoy en día, Arizona tiene uno de los programas de evaluación del rendimiento judicial más progresistas e integrales de los Estados Unidos. Este artículo ofrece una mirada crítica a las fortalezas y debilidades del programa de Arizona, teniendo en cuenta dos valores clave que el sistema trata de proteger: la responsabilidad judicial y la independencia judicial.

    Vereš, Peter; Chesley, Steven R.

    2017-07-01

    We perform high-fidelity simulations of a wide-field telescopic survey searching for Near-Earth Objects (NEOs) larger than 140 m, focusing on the observation and detection model, as well as detection efficiency and accuracy. As a test survey, we select the Large Synoptic Survey Telescope (LSST). We use its proposed pointings for a 10-year mission, and model the detection of NEOs in the fields. We discuss individual model parameters for magnitude losses, vignetting, fading, asteroid rotation and colors, fill factor, limiting magnitude, rate of motion, field shape and rotation, and survey patterns. We assess results in terms of the cumulative completeness of the detected population as a function of size and time. Additionally, we examine the sources of modeling uncertainty, and derive the overall NEO population completeness for the baseline LSST survey to be 55 ± 5% for NEOs with absolute magnitude brighter than 22. Including already discovered objects and ongoing surveys, the NEO completeness at the end of the LSST baseline survey should reach ˜77%.

    Full Text Available The purpose of an efficient capital market is to mobilize funds from those who have it and route each them to those who can utilize it in the best possible way. India’s financial market is multi-facet but not balanced. It has state of art equity market but relatively less developed and immature corporate bond market. The Indian capital market in the recent year has undergone a lot of innovation in term regulation and mode of operation. A well developed corporate bond market is also essential for financial system stability, efficiency and overall economic growth. However, If we look at the scenario of capital market in India we find that Indian households have traditionally preferred parking their surpluses in bank deposits, government savings schemes and less than 10% of their investments in financial assets in shares, debentures and mutual funds. The Indian capital market has recently put the worst behind and moved towards strong growth. In this back drop the present paper aims to (i identify various grey points of Indian capital market; (ii Evaluated how it performed during post financial crisis period; and (iii suggests necessary policy reforms for a relatively mature capital market.

  10. A Review of Lightweight Thread Approaches for High Performance Computing

    High-level, directive-based solutions are becoming the programming models (PMs) of the multi/many-core architectures. Several solutions relying on operating system (OS) threads perfectly work with a moderate number of cores. However, exascale systems will spawn hundreds of thousands of threads in order to exploit their massive parallel architectures and thus conventional OS threads are too heavy for that purpose. Several lightweight thread (LWT) libraries have recently appeared offering lighter mechanisms to tackle massive concurrency. In order to examine the suitability of LWTs in high-level runtimes, we develop a set of microbenchmarks consisting of commonlyfound patterns in current parallel codes. Moreover, we study the semantics offered by some LWT libraries in order to expose the similarities between different LWT application programming interfaces. This study reveals that a reduced set of LWT functions can be sufficient to cover the common parallel code patterns and that those LWT libraries perform better than OS threads-based solutions in cases where task and nested parallelism are becoming more popular with new architectures.

  11. A systematic review of childhood maltreatment assessments in population-representative surveys since 1990.

    Directory of Open Access Journals (Sweden)

    Wendy Hovdestad

    Full Text Available Population-representative surveys that assess childhood maltreatment and health are a valuable resource to explore the implications of child maltreatment for population health. Systematic identification and evaluation of such surveys is needed to facilitate optimal use of their data and to inform future research.To inform researchers of the existence and nature of population-representative surveys relevant to understanding links between childhood maltreatment and health; to evaluate the assessment of childhood maltreatment in this body of work.We included surveys that: 1 were representative of the non-institutionalized population of any size nation or of any geopolitical region ≥ 10 million people; 2 included a broad age range (≥ 40 years; 3 measured health; 4 assessed childhood maltreatment retrospectively; and 5 were conducted since 1990. We used Internet and database searching (including CINAHL, Embase, ERIC, Global Health, MEDLINE, PsycINFO, Scopus, Social Policy and Practice: January 1990 to March 2014, expert consultation, and other means to identify surveys and associated documentation. Translations of non-English survey content were verified by fluent readers of survey languages. We developed checklists to abstract and evaluate childhood maltreatment content.Fifty-four surveys from 39 countries met inclusion criteria. Sample sizes ranged from 1,287-51,945 and response rates from 15%-96%. Thirteen surveys assessed neglect, 15 emotional abuse; 18 exposure to family violence; 26 physical abuse; 48 sexual abuse. Fourteen surveys assessed more than three types; six of these were conducted since 2010. In nine surveys childhood maltreatment assessments were detailed (+10 items for at least one type of maltreatment. Seven surveys' assessments had known reliability and/or validity.Data from 54 surveys can be used to explore the population health relevance of child maltreatment. Assessment of childhood maltreatment is not comprehensive but

    A survey and critical review were undertaken of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, including California schools. Over 450 relevant publications were obtained and reviewed, including papers published in the archival peer-reviewed scientific literature, proceedings of scientific meetings, government reports, 77 NIOSH Health Hazard Evaluation Reports (HHER) and 70 reports on investigations of problem schools in California. Most of the reviewed literature was for complaint or problem schools. The types of health symptoms reported in schools were very similar to those defined as sick building syndrome (SBS) symptoms, although this may be due, at least in part, to the type of health symptom questionnaires used. Some of the symptoms, e.g., wheezing, are indicative of asthma. In the studies in which complaint and noncomplaint buildings or areas were compared, complaint buildings generally had higher rates of health symptoms.

    United Nation's Sustainable Development Goals and the World Health Organization's Global Monitoring Framework support a strong global commitment to reducing the high burden of cervical and breast cancers among low- and middle-income countries. Strategies include vaccination, screening, and early diagnosis. Population-based surveys, such as those conducted by the Demographic and Health Surveys (DHS) Program, can collect the information needed to guide cancer control efforts in a standardized comparable manner. We identified and evaluated the breadth of breast and cervical cancer screening information that was collected by the DHS from 1984 through 2015. Then, we determined if these surveys currently provide the specific and measurable data about both the quantity and quality of cancer screening needed to guide national efforts to reduce the overall effects of cervical and breast cancers. We searched the DHS website to identify surveys conducted between the start of the DHS Program in 1984 and November 2015 that included questions about breast and cervical cancer screening. The relevant questions were extracted from the questionnaire, translated into English, and grouped by themes. Of the 90 countries where DHS surveys have been implemented, cervical cancer screening questions were included in 22 countries (24.4%) and breast cancer screening questions in 18 countries (20.0%). The common themes identified were disease knowledge, screening knowledge, screening practice, and screening outcomes. Most countries with survey questionnaires available for review addressed at least one aspect of screening practice (88.9% of cervical and 87.5% of breast), although few countries queried knowledge and outcomes. Questions that assess varied aspects of breast and cervical cancer screening have been incorporated into relatively few DHS surveys. The themes identified could guide the design of a standard set of questions for use in future population-based surveys and enable evaluation

    This article systematically reviews empirical studies that examine associations between alcohol consumption and men's sexual aggression with the goal of identifying major findings; gaps in current knowledge; and directions for future research, practice, and policy. We identified 25 cross-sectional surveys, 6 prospective studies, and 12 alcohol administration experiments published between 1993 and August 2013 with male college students and young adult (nonincarcerated) samples. Many cross-sectional surveys have demonstrated that distal and proximal measures of men's alcohol consumption are positively associated with sexual assault perpetration, although very few of these studies evaluated how alcohol interacts with other risk and protective factors to exacerbate or inhibit sexual aggression. There are surprisingly few surveys that examine alcohol's effects at the event level and over short-time intervals to identify how changes in alcohol consumption are associated with changes in perpetration status. Alcohol administration studies suggest some important mechanisms that warrant additional investigation. © The Author(s) 2014.

  16. The role of the extrajudicial accounting survey in reviewing and certifying financial statements. A case study

    Directory of Open Access Journals (Sweden)

    Busuioceanu, S.

    2013-12-01

    Full Text Available As our society develops, transactions between companies become increasingly complex. The amount of data involved is bigger and bigger, while decision makers are more and more likely to receive incorrect information. In order to improve the reliability and relevancy of the information they use, decision makers resort to assurance services which can be performed by financial auditors, chartered accountants or other specialists. The contribution of the accounting survey to the prevention of damage, the preservation of the integrity of the cultural assets and the compliance with the law are efficient not only given their use as evidence in court, but also as a means to ground decisions or to guarantee the fact that the accounting balance sheet offers a true, clear and complete view over the assets, financial statements, the profit (loss for the period. These financial and accounting analyses and certifications of the assets and the possibility of the economic agent to make profit and, consequently, to be financially efficient, represents a proof of reliability for the other economic agents when establishing sound economic rapports.

    The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument baseline. This paper reviews the characteristics of the selected configuration and presents its expected performance. The RVS is a 2.0 by 1.6 degree integral field spectrograph, dispersing the light of all sources entering its field of view with a resolving power R=11 500 over the wavelength range [848, 874] nm. The RVS will continuously and repeatedly scan the sky during the 5 years of the Gaia mission. On average, each source will be observed 102 times over this period. The RVS will collect the spectra of about 100-150 million stars up to magnitude V~17-18. At the end of the mission, the RVS will provide radial velocities with precisions of ~2 km/s at V=15 and \\~15-20 km/s at V=17, for a solar metallicity G5 dwarf. The RVS will also provide rotational velocities, with precisions (at the end of the mission) for late type stars of sigma...

    2006-07-01

    In an effort to gather information on forced power outages, the Canadian Electricity Association conducted a survey using its Equipment Reliability Information System (ERIS). The survey covered elements such as transmission equipment reliability in terms of transmission lines, cables, transformer banks, circuit breakers, synchronous compensators, static compensators, shunt reactor banks, shunt capacitor banks, and series capacitor banks. The survey provided details regarding the cause of failure, design information, and an in-depth analysis of statistics regarding the number of outages, frequency, total time, mean duration, median duration, and availability. The survey revealed that the primary causes of outages were defective equipment, adverse weather, adverse environment, system conditions, human error, and foreign interference. tabs., figs.

    The main advantages of online questionnaires are the speed of data collection and cost savings, but response rates are usually low. This study analyzed response rates and associated factors among health professionals in three opinion surveys in the autonomous region of Madrid. The participants, length of the questionnaire and topic differed among the three surveys. The surveys were conducted by using paid Internet software. The institutional e-mail addresses of distinct groups of health professionals were used. Response rates were highest in hospitals (up to 63%) and administrative services and were lowest in primary care (less than 33%). The differences in response rates were analyzed in primary care professionals according to age, sex and professional category and only the association with age was statistically significant. None of the surveys achieved a response rate of 60%. Differences were observed according to workplace, patterns of Internet usage, and interest in the subject. Copyright © 2011 SESPAS.

  17. A guide to performing a peer review of randomised controlled trials.

    Science.gov (United States)

    Del Mar, Chris; Hoffmann, Tammy C

    2015-11-02

    Peer review of journal articles is an important step in the research process. Editors rely on the expertise of peer reviewers to properly assess submissions. Yet, peer review quality varies widely and few receive training or guidance in how to approach the task. This paper describes some of the main steps that peer reviewers in general and, in particular, those performing reviewes of randomised controlled trials (RCT), can use when carrying out a review. It can be helpful to begin with a brief read to acquaint yourself with the study, followed by a detailed read and a careful check for flaws. These can be divided into 'major' (problems that must be resolved before publication can be considered) and 'minor' (suggested improvements that are discretionary) flaws. Being aware of the appropriate reporting checklist for the study being reviewed (such as CONSORT and its extensions for RCTs) can also be valuable. Competing interests or prejudices might corrode the review, so ensuring transparency about them is important. Finally, ensuring that the paper's strengths are acknowledged along with a dissection of the weaknesses provides balance and perspective to both authors and editors. Helpful reviews are constructive and improve the quality of the paper. The proper conduct of a peer review is the responsibility of all who accept the role.

    ABSTRACT Background: Quality indicators are measured aspects of healthcare, reflecting the performance of a healthcare provider or healthcare system. They have a crucial role in programmes to assess and improve healthcare. Many performance measures for primary care have been developed. Only the Catalan model for patient safety in primary care identifies key domains of patient safety in primary care. Objective: To present an international framework for patient safety indicators in primary care. Methods: Literature review and online Delphi-survey, starting from the Catalan model. Results: A set of 30 topics is presented, identified by an international panel and organized according to the Catalan model for patient safety in primary care. Most topic areas referred to specific clinical processes; additional topics were leadership, people management, partnership and resources. Conclusion: The framework can be used to organize indicator development and guide further work in the field. PMID:26339833

  19. CMOS Image Sensor with On-Chip Image Compression: A Review and Performance Analysis

    Directory of Open Access Journals (Sweden)

    Milin Zhang

    2010-01-01

    Full Text Available Demand for high-resolution, low-power sensing devices with integrated image processing capabilities, especially compression capability, is increasing. CMOS technology enables the integration of image sensing and image processing, making it possible to improve the overall system performance. This paper reviews the current state of the art in CMOS image sensors featuring on-chip image compression. Firstly, typical sensing systems consisting of separate image-capturing unit and image-compression processing unit are reviewed, followed by systems that integrate focal-plane compression. The paper also provides a thorough review of a new design paradigm, in which image compression is performed during the image-capture phase prior to storage, referred to as compressive acquisition. High-performance sensor systems reported in recent years are also introduced. Performance analysis and comparison of the reported designs using different design paradigm are presented at the end.

    2015-12-15

    The calibration methods of neutron-measuring devices such as the neutron survey meter have advantages and disadvantages. To compare the calibration factors obtained by the shadow cone method and semi-empirical method, 10 neutron survey meters of five different types were used in this study. This experiment was performed at the Korea Atomic Energy Research Institute (KAERI; Daejeon, South Korea), and the calibration neutron fields were constructed using a {sup 252}Californium ({sup 252}Cf) neutron source, which was positioned in the center of the neutron irradiation room. The neutron spectra of the calibration neutron fields were measured by a europium-activated lithium iodide scintillator in combination with KAERI's Bonner sphere system. When the shadow cone method was used, 10 single moderator-based survey meters exhibited a smaller calibration factor by as much as 3.1 - 9.3% than that of the semi-empirical method. This finding indicates that neutron survey meters underestimated the scattered neutrons and attenuated neutrons (i.e., the total scatter corrections). This underestimation of the calibration factor was attributed to the fact that single moderator-based survey meters have an under-ambient dose equivalent response in the thermal or thermal-dominant neutron field. As a result, when the shadow cone method is used for a single moderator-based survey meter, an additional correction and the International Organization for Standardization standard 8529-2 for room-scattered neutrons should be considered.

  3. What Is the Relationship Between a Preclerkship Portfolio Review and Later Performance in Clerkships?

    O'Brien, Celia Laird; Thomas, John X; Green, Marianne M

    2017-06-20

    Medical educators struggle to find effective ways to assess essential competencies such as communication, professionalism, and teamwork. Portfolio-based assessment provides one method of addressing this problem by allowing faculty reviewers to judge performance, as based on a longitudinal record of student behavior. At the Feinberg School of Medicine, the portfolio system measures behavioral competence using multiple assessments collected over time. This study examines whether a preclerkship portfolio review is a valid method of identifying problematic student behavior affecting later performance in clerkships. The authors divided students into two groups based on a summative preclerkship portfolio review in 2014: students who had concerning behavior in one or more competencies and students progressing satisfactorily. They compared how students in these groups later performed on two clerkship outcomes as of October 2015: final grades in required clerkships, and performance on a clerkship clinical composite score. They used Mann-Whitney tests and multiple linear regression to examine the relationship between portfolio review results and clerkship outcomes. They used USMLE Step 1 to control for knowledge acquisition. Students with concerning behavior preclerkship received significantly lower clerkship grades than students progressing satisfactorily (P = .002). They also scored significantly lower on the clinical composite score (P portfolio review can identify behaviors that impact clerkship performance. A comprehensive portfolio system is a valid way to measure behavioral competencies.

    2016-01-01

    Background Conflicts of interest may bias the findings of systematic reviews. The objective of this methodological survey was to assess the frequency and different types of conflicts of interest that authors of Cochrane and non-Cochrane systematic reviews report. Methods We searched for systematic reviews using the Cochrane Database of Systematic Reviews and Ovid MEDLINE (limited to the 119 Core Clinical Journals and the year 2015). We defined a conflict of interest disclosure as the reporting of whether a conflict of interest exists or not, and used a framework to classify conflicts of interest into individual (financial, professional and intellectual) and institutional (financial and advocatory) conflicts of interest. We conducted descriptive and regression analyses. Results Of the 200 systematic reviews, 194 (97%) reported authors' conflicts of interest disclosures, typically in the main document, and in a few cases either online (2%) or on request (5%). Of the 194 Cochrane and non-Cochrane reviews, 49% and 33%, respectively, had at least one author reporting any type of conflict of interest (p=0.023). Institutional conflicts of interest were less frequently reported than individual conflicts of interest, and Cochrane reviews were more likely to report individual intellectual conflicts of interest compared with non-Cochrane reviews (19% and 5%, respectively, p=0.004). Regression analyses showed a positive association between reporting of conflicts of interest (at least one type of conflict of interest, individual financial conflict of interest, institutional financial conflict of interest) and journal impact factor and between reporting individual financial conflicts of interest and pharmacological versus non-pharmacological intervention. Conclusions Although close to half of the published systematic reviews report that authors (typically many) have conflicts of interest, more than half report that they do not. Authors reported individual conflicts of interest

  5. A systematic review and meta-analysis of seroprevalence surveys of ebolavirus infection

    2017-01-01

    Asymptomatic ebolavirus infection could greatly influence transmission dynamics, but there is little consensus on how frequently it occurs or even if it exists. This paper summarises the available evidence on seroprevalence of Ebola, Sudan and Bundibugyo virus IgG in people without known ebolavirus disease. Through systematic review, we identified 51 studies with seroprevalence results in sera collected from 1961 to 2016. We tabulated findings by study population, contact, assay, antigen and positivity threshold used, and present seroprevalence point estimates and 95% confidence intervals. We classified sampled populations in three groups: those with household or known case-contact; those living in outbreak or epidemic areas but without reported case-contact; and those living in areas with no recorded cases of ebolavirus disease. We performed meta-analysis only in the known case-contact group since this is the only group with comparable exposures between studies. Eight contact studies fitted our inclusion criteria, giving an overall estimate of seroprevalence in contacts with no reported symptoms of 3.3% (95% CI 2.4–4.4, P<0.001), but with substantial heterogeneity.

    1996-01-01

    Many nursing specialty organizations have completed Delphi surveys to establish their research priorities. The Society of Otorhinolaryngology-Head and Neck Nurses (SOHN) is currently conducting its own Delphi survey to the same end. This paper reviews the various Delphi methods employed by specialty nursing organizations on their members between 1985 and 1995. The studies reviewed are carefully limited to those commissioned by specialty nursing organizations and exclusive of those conducted by independent researchers who may have utilized specialty organization members. It presents an introduction to and definition of the Delphi methodology, as well as delving into methodologic and practical aspects of implementing a Delphi survey. It adds to the literature some information previously lacking on cost and time lines for studies, and will serve as a useful guide for future specialty nursing organizations who undertake a Delphi study as a novice effort. It intentionally does not recount the research priorities identified because it does not want to influence, in any way, responses of SOHN members involved in the ongoing Round I Delphi.

The purpose of this review is to summarize these articles and examine the impact of team process behaviours on clinical performance. We conducted a literature search in five major databases. Inclusion criteria were: English peer-reviewed papers published between January 2001 and May 2012, which showed or tried to show (i) a statistical relationship of a team process variable and clinical performance or (ii) an improvement of a performance variable through a team process intervention. Study quality was assessed using predefined quality indicators. For every study, we calculated the relevant effect sizes. We included 28 studies in the review, seven of which were intervention studies. Every study reported at least one significant relationship between team processes or an intervention and performance. Also, some non-significant effects were reported. Most of the reported effect sizes were large or medium. The study quality ranged from medium to high. The studies are highly diverse regarding the specific team process behaviours investigated and also regarding the methods used. However, they suggest that team process behaviours do influence clinical performance and that training results in increased performance. Future research should rely on existing theoretical frameworks, valid, and reliable methods to assess processes such as teamwork or coordination and focus on the development of adequate tools to assess process performance, linking them with outcomes in the clinical setting.

    Organisation performance measurement is relevant for non-profit charitable organisations as they strive for security in an increasingly competitive funding environment. This study aimed to identify the priority measures and indicators of organisational performance of an Australian non-government charitable organisation that delivers non-acute health services. Seventy-seven and 59 participants across nine stakeholder groups responded to a two-staged Delphi technique study of a case study organisation. The stage one questionnaire was developed using information garnered through a detailed review of literature. Data from the first round were aggregated and analysed for the stage two survey. The final data represented a group consensus. Quality of care was ranked the most important of six organisational performance measures. Service user satisfaction was ranked second followed by financial performance, internal processes, employee learning and growth and community engagement. Thirteen priority indicators were determined across the six measures. Consensus was reached on the priority organisational performance measures and indicators. Stakeholders of the case study organisation value evidence-based practice, technical strength of services and service user satisfaction over more commercially orientated indicators.

  12. A Comprehensive Survey on Hierarchical-Based Routing Protocols for Mobile Wireless Sensor Networks: Review, Taxonomy, and Future Directions

    2017-01-01

    Full Text Available Introducing mobility to Wireless Sensor Networks (WSNs puts new challenges particularly in designing of routing protocols. Mobility can be applied to the sensor nodes and/or the sink node in the network. Many routing protocols have been developed to support the mobility of WSNs. These protocols are divided depending on the routing structure into hierarchical-based, flat-based, and location-based routing protocols. However, the hierarchical-based routing protocols outperform the other routing types in saving energy, scalability, and extending lifetime of Mobile WSNs (MWSNs. Selecting an appropriate hierarchical routing protocol for specific applications is an important and difficult task. Therefore, this paper focuses on reviewing some of the recently hierarchical-based routing protocols that are developed in the last five years for MWSNs. This survey divides the hierarchical-based routing protocols into two broad groups, namely, classical-based and optimized-based routing protocols. Also, we present a detailed classification of the reviewed protocols according to the routing approach, control manner, mobile element, mobility pattern, network architecture, clustering attributes, protocol operation, path establishment, communication paradigm, energy model, protocol objectives, and applications. Moreover, a comparison between the reviewed protocols is investigated in this survey depending on delay, network size, energy-efficiency, and scalability while mentioning the advantages and drawbacks of each protocol. Finally, we summarize and conclude the paper with future directions.

  13. Performance monitoring in autism spectrum disorders: A systematic literature review of event-related potential studies.

    Autism spectrum disorder (ASD) is marked by impairments in social-emotional situations, executive functioning, and behavioral regulation. These symptoms may be related to deficits in performance monitoring, i.e., the ability to observe and evaluate one's own behavior and performance which is necessary for the regulation of future behavior. The present literature review investigated electroencephalic correlates of performance monitoring in ASD. Event-related potentials (ERPs) considered in this review included internal performance monitoring components (error-related negativity, error positivity), external performance monitoring components (feedback-related negativity, feedback-P3), and observational performance monitoring components (observer error-related negativity, observer feedback-related negativity). The majority of studies point to reduced internal performance monitoring in ASD. External performance monitoring in reward-processing paradigms, where rewards are independent of performance, seems to be intact in ASD. So far, no studies have investigated the observer error-related negativity in ASD. Available data on the observer feedback-related negativity are inconclusive, since only two studies with differential study results investigated this construct in ASD. In general, results suggest that individuals with ASD have problems with internal performance monitoring and with learning from external, abstract feedback. In contrast, the processing of external, concrete feedback seems to be largely intact in ASD.

    2007-06-01

    Brain computer interfaces (BCIs) aim at providing a non-muscular channel for sending commands to the external world using the electroencephalographic activity or other electrophysiological measures of the brain function. An essential factor in the successful operation of BCI systems is the methods used to process the brain signals. In the BCI literature, however, there is no comprehensive review of the signal processing techniques used. This work presents the first such comprehensive survey of all BCI designs using electrical signal recordings published prior to January 2006. Detailed results from this survey are presented and discussed. The following key research questions are addressed: (1) what are the key signal processing components of a BCI, (2) what signal processing algorithms have been used in BCIs and (3) which signal processing techniques have received more attention?

    2013-06-01

    The need for athletes to travel long distances has spurred investigation into the effect of air travel across multiple time zones on athletic performance. Rapid eastward or westward travel may negatively affect the body in many ways; therefore, strategies should be employed to minimise these effects which may hamper athletic performance. In this review, the fundamentals of circadian rhythm disruption are examined along with additional effects of airline travel including jet lag, sleep deprivation, travel at altitude and nutritional considerations that negatively affect performance. Evidence-based recommendations are provided at the end of the manuscript to minimise the effects of airline travel on performance.

    Purpose: In light of concerns regarding the quality of radiation treatment delivery, we surveyed the practice of quality assurance peer review chart rounds at American academic institutions. Methods and Materials: An anonymous web-based survey was sent to the chief resident of each institution across the United States. Results: The response rate was 80% (57/71). The median amount of time spent per patient was 2.7 minutes (range, 0.6-14.4). The mean attendance by senior physicians and residents was 73% and 93%, respectively. A physicist was consistently present at peer review rounds in 66% of departments. There was a close association between attendance by senior physicians and departmental organization: in departments with protected time policies, good attendance was 81% vs. 31% without protected time (p = 0.001), and in departments that documented attendance, attending presence was 69% vs. 29% in departments without documentation (p < 0.05). More than 80% of institutions peer review all external beam therapy courses; however, rates were much lower for other modalities (radiosurgery 58%, brachytherapy 40%-47%). Patient history, chart documentation, and dose prescription were always peer reviewed in >75% of institutions, whereas dosimetric details (beams, wedges), isodose coverage, intensity-modulated radiation therapy constraints, and dose-volume histograms were always peer reviewed in 63%, 59%, 42%, and 50% of cases, respectively. Chart rounds led to both minor (defined as a small multileaf collimator change/repeated port film) and major (change to dose prescription or replan with dosimetry) treatment changes. Whereas at the majority of institutions changes were rare (<10% of cases), 39% and 11% of institutions reported that minor and major changes, respectively, were made to more than 10% of cases. Conclusion: The implementation of peer review chart rounds seems inconsistent across American academic institutions. Brachytherapy and radiosurgical procedures are

    Systematic review of the effect of intraoperative technical performance on patient outcomes. The operating room is a high-stakes, high-risk environment. As a result, the quality of surgical interventions affecting patient outcomes has been the subject of discussion and research for years. MEDLINE, EMBASE, PsycINFO, and Cochrane databases were searched. All surgical specialties were eligible for inclusion. Data were reviewed in regards to the methods by which technical performance was measured, what patient outcomes were assessed, and how intraoperative technical performance affected patient outcomes. Quality of evidence was assessed using the Medical Education Research Study Quality Instrument (MERSQI). Of the 12,758 studies initially identified, 24 articles (7775 total participants) were ultimately included in this review. Seventeen studies assessed the performance of the faculty alone, 2 assessed both the faculty and trainees, 1 assessed trainees alone, and in 4 studies, the level of the operating surgeon was not specified. In 18 studies, a performance assessment tool was used. Patient outcomes were evaluated using intraoperative complications, short-term morbidity, long-term morbidity, short-term mortality, and long-term mortality. The average MERSQI score was 11.67 (range 9.5-14.5). Twenty-one studies demonstrated that superior technical performance was related to improved patient outcomes. The results of this systematic review demonstrated that superior technical performance positively affects patient outcomes. Despite this initial evidence, more robust research is needed to directly assess intraoperative technical performance and its effect on postoperative patient outcomes using meaningful assessment instruments and reliable processes.

    [Purpose] This study investigated whether the Canadian Occupational Performance Measure is a suitable outcome measure for assessing patients with stroke in research and clinical settings. [Subjects and Methods] The study included into two parts: (1) an investigation of the reliability and validity of the Canadian Occupational Performance Measure for patients with stroke and (2) an exploration of Canadian Occupational Performance Measure results in randomized controlled trials of patients with stroke. For this review, the study searched the MEDLINE, PubMed, and CINAHL Plus with Full Text databases for articles published before September 2015. [Results] Finally, three eligible articles were collected in part 1, and ten randomized controlled trials studies were collected in part 2. The findings of part 1 revealed that the Canadian Occupational Performance Measure had efficient test-retest reliability, however, the Canadian Occupational Performance Measure revealed weak associations with other assessment tools such as Barthel Index used for patients with stroke. Six of the randomized controlled trials studies used the Canadian Occupational Performance Measure as a primary outcome and two as a secondary outcome, while the other two as a goal-setting instrument. [Conclusion] This review indicates that the Canadian Occupational Performance Measure is appropriate for clinicians, including physiotherapists, in assessing outcome for patients with stroke. The Canadian Occupational Performance Measure can assist patients in identifying their outcome performance and provide therapists with directions on interventions.

    Land subsidence in Semarang is a severe hazard threatening people and urban infrastructure. Land subsidence is suspected expand to North Demak. It shows that has been leading to severe and costly damages to urban infrastructure such as buildings and roads. Another disaster like flooding will ruin the city frequently and is increasingly severely affecting the living conditions. The Principle of land subsidence monitoring with a GPS is to determine the coordinates of a point on a carefully selected location and are conducted periodically at regular. By studying the characteristic and speed of change in ellipsoid height of the point - the point of the survey is a survey to the next, then the greater the reduction in soil characteristics and will be known. This paper mainly discusses the results obtained by GPS surveys that have been conducted in 2011, 2013, 2014 and2015. Land subsidence in Semarang until now still occur, especially in the northern region of Semarang. In the range of 2011-2015 land subsidence rates of 15 cm / year besides that for studying land subsidence in Demak, there was 10 Bench Mark was established.

  10. Performance management of the public healthcare services in Ireland: a review.

    Science.gov (United States)

    Mesabbah, Mohammed; Arisha, Amr

    2016-01-01

    Performance Management (PM) processes have become a potent part of strategic and service quality decisions in healthcare organisations. In 2005, the management of public healthcare in Ireland was amalgamated into a single integrated management body, named the Health Service Executive (HSE). Since then, the HSE has come up with a range of strategies for healthcare developments and reforms, and has developed a PM system as part of its strategic planning. The purpose of this paper is to review the application of PM in the Irish Healthcare system, with a particular focus on Irish Hospitals and Emergency Services. An extensive review of relevant HSE's publications from 2005 to 2013 is conducted. Studies of the relevant literature related to the application of PM and of international best practices in healthcare performance systems are also presented. PM and performance measurement systems used by the HSE include many performance reports designed to monitor performance trends and strategic goals. Issues in the current PM system include inconsistency of measures and performance reporting, unclear strategy alignment, and deficiencies in reporting (e.g. feedback and corrective actions). Furthermore, PM processes have not been linked adequately into Irish public hospitals' management systems. The HSE delivers several services such as mental health, social inclusion, etc. This study focuses on the HSE's PM framework, with a particular interest in acute hospitals and emergency services. This is the first comprehensive review of Irish healthcare PM since the introduction of the HSE. A critical analysis of the HSE reports identifies the shortcomings in its current PM system.

    An anonymous questionnaire was used to investigate the status quo of ethics review of human subject experiments among postgraduate students in clinical practice with the main conclusions as follows: Human subject experiments make up a large ratio of clinical research; the construction of an ethics review has been initially formulated, but there exists a gap in ethics awareness between advisors and the postgraduates with the desperate need to receive ethics review. It is necessary to realize the importance of informed consent and to strengthen the strict supervision of placebo application.

    2012-11-01

    Although the practice of medicine is built on a foundation of ethics, science, and common sense, the increasing complexity of medical interventions, social interactions, and societal norms of behavior challenges the ethical practice of aesthetic surgeons. We report a survey of the opinions, practices, and attitudes of experienced and novice facial plastic surgeons. The survey consisted of 15 clinical vignettes addressing ethical quandaries in aesthetic rhinoplasty. The vignettes are based on the experience and observations of the senior author (P.A.A.) over nearly 30 years of practice and teaching. Fellowship directors and facial plastic surgery fellows of the American Academy of Facial Plastic and Reconstructive Surgery were surveyed anonymously. Five of the 15 vignettes demonstrated significant differences between the responses of the fellowship directors and the fellows. No single vignette had a unanimous consensus in either group. Aesthetic rhinoplasty surgeons encounter ethical issues that should be reflected on by both experienced and inexperienced facial plastic surgeons, preferably before being faced with them in practice. We present a practical approach to ethical issues in clinical practice. Our survey can also be used as a stimulus for further discussion and teaching.

  18. Interventions for music performance anxiety: results from a systematic literature review

    Directory of Open Access Journals (Sweden)

    Ana Beatriz Burin

    Full Text Available Abstract Background Music performance anxiety (MPA is characterised by fears related to performing music. It may result in damages to personal life and professional career, so treatment and prevention are very important. Objective To undertake a systematic literature review on the effectiveness/efficacy of MPA interventions and to integrate these findings to those in the literature reviewed previously. Methods We used PubMed, PsycINFO and SciELO databases and keywords music*, performance anxiety, treatment, therapy and intervention and manual research. We selected articles published between October-2002/July-2016. Results Out of 97 articles, 23 were reviewed. Sixteen studies presented inter-group experimental design, and seven presented pre-post experimental design. The intervention modalities reviewed were cognitive behavioural therapy (CBT, virtual reality exposure, biofeedback, yoga, meditation, music therapy and the Alexander technique. Although the interventions presented some indicators of efficacy in the MPA outcomes and improvement in performance quality, important methodological limitations were observed: low number of individuals and non-specific criteria for their inclusion/exclusion. This reinforces previous findings regarding methodological fragilities associated with this context. Discussion CBT is the most frequently studied modality and with the greatest number of effectiveness indicators. The remaining modalities indicate tendencies in positive outcomes that require further and efficient investigation in more rigorous studies with greater methodological control.

    Focused Assessment with Sonography for Trauma (commonly abbreviated as FAST) is considered for patients with blunt abdominal trauma as the gold standard for accident assessment in site. This method is increasingly used even by not radiologists professionals, as well as by nurses who works in emergency settings. This systematic review is aimed at evaluating the effectiveness of ultrasound FAST performed by nurses in emergencies department. Seven databases of primary and secondary literature as well as three national journals relevant to the field were consulted. The review was conducted between March and August 2011 developing 9 search strings. Articles have been critically reviewed by two authors independently. No restriction on language or time of publication have been used. A total of 4767 documents were displayed, of those only 4 were considered to be reviewed. A total of 1035 FAST ultrasound performed by nurses were included. The results show that the use of ultrasound FAST performed by trained nurses is very effective, with a sensitivity of 84% (95% CI 72.1-92.2) and a specificity of 97.37% (95% CI 92.55-99.10) . Practice execution time was an average of 156 seconds (2.6 minutes), median time of 138 seconds (range = 76 to 357). Just one study specified the training course that nurses were required to attend. To sum up, FAST ultrasound performed by nurses have an important role in emergencies management as well as in triage setting as valid screening tool.

    Predicted workforce shortages have resulted in government initiatives to increase student numbers in preregistration nursing education. In tandem schools of nursing need to ensure students' progress and complete. The aim of this review was to identify factors that influence preregistration nursing students' academic performance, clinical performance and attrition. An integrative review of both quantitative and qualitative literature was conducted using validated appraisal checklists. The review included studies published from 1999 to 2011 in the databases: MEDLINE, CINAHL, Proquest nursing, Proquest Education (via Proquest 5000), ERIC, Journals@Ovid, PsychINFO and ScienceDirect. Studies were categorised according to their impact on academic progression, clinical progression and attrition. Forty four studies were found; most used quantitative methodologies. The review identified that few studies explored factors that impact on students' clinical performance. The four categories that potentially impact on nursing students' academic performance and attrition were: demographic, academic, cognitive and personality/behavioural factors. The challenge for universities committed to students' success is to develop strategies aimed at addressing these factors that are appropriate to specific contexts and student cohorts.

    Full Text Available This study seeks to assess the state-of-the-art on the workplace diversity – firm performance relationship. Based on a review of academic research on workplace diversity and firm performance published in nine leading journals in the field of management during the period 2000-2009, it addresses the following research questions: a. How are diversity and firm performance constructs defined? b. What are the findings of research linking workplace diversity and firm performance? c. What factors mediate and/or moderate the diversity-performance relationship? Based on the findings of extant research, we develop a model to explain and interpret the diversity – firm performance relationship, and understand its implications.

  12. Do indoor environments in schools influence student performance? A review of the literature

    Energy Technology Data Exchange (ETDEWEB)

    Mendell, Mark J.; Heath, Garvin A.

    2004-11-24

    Limited research is available on potential adverse effects of school environments on academic performance, despite strong public concern. We examine the scientific evidence relevant to this relationship by reviewing available research relating schools and other indoor environments to human performance or attendance. As a primary focus, we critically review evidence for direct relationships between indoor environmental quality (IEQ) in buildings and performance or attendance. As a secondary focus, we summarize, without critique, evidence on potential connections indirectly linking IEQ to performance or attendance: relationships between IEQ and health, between health and performance or attendance, and between attendance and performance. The most persuasive direct evidence showed increases in indoor concentrations of nitrogen dioxide and outdoor concentrations of several specific pollutants to be related to reduced school attendance. The most persuasive indirect evidence showed indoor dampness and microbiologic pollutants to be related to asthma and respiratory infections, which have in turn been related to reduced performance and attendance. Furthermore, a substantial scientific literature links poor IEQ (e.g., low ventilation rate, excess moisture or formaldehyde) with respiratory and other health effects in children and adults. Overall, evidence suggests that poor IEQ in schools can influence the performance and attendance of students, primarily through health effects from indoor pollutants. Also, inadequate IEQ in schools seems sufficiently common to merit strong public concern. Evidence is available to justify (1) immediate actions to protect IEQ in schools and (2) focused research on exposures, prevention, and causation, to better guide policies and actions on IEQ in schools.

    2012-10-01

    Full Text Available The development of alternative fuels such as natural gases has become very essential because of the continuously decrease in the petroleum reserves and also their contribution for pollutants. In this paper, a survey of research papers on the utilization of Compressed Natural Gas in the Internal Combustion engines along with its effects on the performance and emissions is done. It is revealed that the performance characteristics except thermal efficiency and exhaust temperature, various other performance parameters like brake mean effective pressure, power, torque and brake specific fuel consumption are decreased for CNG fuelled engine while the emission characteristics of unburnt hydrocarbon, Carbon monoxide and Carbon-di-oxide except nitrogen oxides are better for CNG compared to petrol and diesel engines. The improvement in performance is observed with the addition of hydrogen.

Results: We present a basic time point discordant ratio and a cases discordance ratio based on a range of aggregated time points per case for RECIST datasets. Conclusions: We propose basic ratios that that might be useful to improve reviewer performance monitoring models

  15. Age-Related Changes in Performance and Recovery Kinetics in Masters Athletes: A Narrative Review.

    Science.gov (United States)

    Borges, Nattai; Reaburn, Peter; Driller, Matthew; Argus, Christos

    2016-01-01

    Despite increasing participation rates in masters sport and extensive research examining age-related changes in performance, little is known about the effect of age on recovery kinetics in masters athletes. This narrative review focuses on the relationship between aging and sport participation, and the effect on both performance and recovery following an exercise bout. Current research suggests the effect of age on performance and recovery may be smaller than originally suggested and that increasing sedentary lifestyles appear to play a larger role in any observed decrements in performance and recovery in masters athletes. Currently, it appears that performance decrements are inevitable with age. However, performance capacities can be maintained through systematic physical training. Moreover, the limited current research suggests there may be an age effect on recovery kinetics following an exercise bout, although further research is required to understand the acute and chronic recovery processes in the masters athlete.

  16. The level of evidence for emergency department performance indicators: systematic review.

    Madsen, Michael; Kiuru, Sampsa; Castrèn, Maaret; Kurland, Lisa

    2015-10-01

    The aim of this study was to perform a comprehensive systematic review of emergency department performance indicators in relation to evidence. A systematic search was performed through PUBMED, EMBASE, CINAHL and COCHRANE databases with (and including synonyms of) the search words: [emergency medicine OR emergency department] AND [quality indicator(s) OR performance indicator(s) OR performance measure(s)]. Articles were included according to the inclusion/exclusion criteria using the PRISMA protocol. The level of evidence was rated according to the evidence levels by the Oxford Centre for Evidence-Based Medicine. Performance indicators were extracted and organized into five categories; outcome, process, satisfaction, equity and structural/organizational measures. Six thousand four hundred and forty articles were initially identified; 127 provided evidence for/against a minimum of one performance indicator: these were included for further study. Of the 127 articles included, 113 (92%) were primary research studies and only nine (8%) were systematic reviews. Within the 127 articles, we found evidence for 202 individual indicators. Approximately half (n=104) of all this evidence (n=202) studied process-type indicators. Only seven articles (6%) qualified for high quality (level 1b). Sixty-six articles (51%) were good retrospective quality (level 2b or better), whereas the remaining articles were either intermediate quality (25% level 3a or 3b) or poor quality (17% level 4 or 5). We found limited evidence for most emergency department performance indicators, with the majority presenting a low level of evidence. Thus, a core group of evidence-based performance indicators cannot currently be recommended on the basis of this broad review of the literature.

    Smetana, F. O.; Summey, D. C.; Johnson, W. D.

    1973-01-01

    The literature on methods for predicting the performance of light aircraft is reviewed. The methods discussed in the review extend from the classical instantaneous maximum or minimum technique to techniques for generating mathematically optimum flight paths. Classical point performance techniques are shown to be adequate in many cases but their accuracies are compromised by the need to use simple lift, drag, and thrust relations in order to get closed form solutions. Also the investigation of the effect of changes in weight, altitude, configuration, etc. involves many essentially repetitive calculations. Accordingly, computer programs are provided which can fit arbitrary drag polars and power curves with very high precision and which can then use the resulting fits to compute the performance under the assumption that the aircraft is not accelerating.

    McLeod, R. W.; Griffin, M. J.

    1989-08-01

    A review of the literature concerned with experimental studies of the effects of translational whole-body vibration on continuous manual control performance is presented. Results from studies of the effects of vibration variables (vibration frequency, magnitude, axis, random vibration and multi-axis vibration) are compared. Evidence of the influence of control system variables (physical characteristics of the control, control gain, system dynamics and display variables) is also provided. Studies of the effects of vibration duration on manual control performance are reviewed separately. A behavioural model is presented to summarize the mechanisms (including vibration breakthrough, visual impairment, neuro-muscular interference and central effects) by which whole-body vibration may interfere with the performance of continuous manual control tasks. The model emphasizes the adaptive ability of the human operator.

    2015-01-01

    Critical reviews offer rich data that can be used to investigate how musical experiences are conceptualized by expert listeners. However, these data also present significant challenges in terms of organization, analysis, and interpretation. This study presents a new systematic method for examining written responses to music, tested on a substantial corpus of music criticism. One hundred critical reviews of Beethoven's piano sonata recordings, published in the Gramophone between August 1934 and July 2010, were selected using in-depth data reduction (qualitative/quantitative approach). The texts were then examined using thematic analysis in order to generate a visual descriptive model of expert critical review. This model reveals how the concept of evaluation permeates critical review. It also distinguishes between two types of descriptors. The first characterizes the performance in terms of specific actions or features of the musical sound (musical parameters, technique, and energy); the second appeals to higher-order properties (artistic style, character and emotion, musical structure, communicativeness) or assumed performer qualities (understanding, intentionality, spontaneity, sensibility, control, and care). The new model provides a methodological guide and conceptual basis for future studies of critical review in any genre.

    Innovative deceased donor intervention strategies have the potential to increase the number and quality of transplantable organs. Yet there is confusion over regulatory and legal requirements, as well as ethical considerations. We surveyed transplant surgeons (n = 294), organ procurement organization (OPO) professionals (n = 83), and institutional review board (IRB) members (n = 317) and found wide variations in their perceptions about research classification, risk assessment for donors and organ transplant recipients, regulatory oversight requirements, and informed consent in the context of deceased donor intervention research. For instance, when presented with different research scenarios, IRB members were more likely than transplant surgeons and OPO professionals to feel that study review and oversight were necessary by the IRBs at the investigator, donor, and transplant center hospitals. Survey findings underscore the need to clarify ethical, legal, and regulatory requirements and their application to deceased donor intervention research to accelerate the pace of scientific discovery and facilitate more transplants. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Chemotherapy-induced peripheral neuropathy (CIPN) is a prominent side effect of the treatment of cancer. Despite this frequent complication, there has been no comprehensive review and quality appraisal of CIPN assessments. The purpose of this study is to provide a definitive quality appraisal of CIPN assessment strategies for clinical use. Relevant studies were identified through database searches of Medline, Embase, CINAHL, and Cochrane. CIPN assessment strategies from included articles were extracted and initially rated by an oncologist and neurophysiologist according to criteria related to assessment depth, comprehensiveness, appropriateness, and reliability. The six highest scoring assessment strategies were the focus of a two-round Delphi survey of a working party of 32 physicians, nurses, and consumers to achieve consensus on the highest rated assessments for each criterion. The database search yielded 117 distinct CIPN assessments that were extracted from 2373 articles. Three patient-reported outcome surveys and three clinician-based assessments were included in the Delphi survey. No consensus was generated regarding the best overall CIPN assessment, although good (≥70%) consensus was achieved regarding the best assessment within each criterion. The Participant Neurotoxicity Questionnaire (PNQ) was rated the highest overall and patient-reported outcome (PRO) assessment, while the Total Neuropathy Score clinical version (TNSc) was the highest rated clinician-based assessment. A diverse range of CIPN assessments currently exists. While several assessments assess CIPN symptoms with adequate comprehensiveness, depth, language, and feasibility, the consensus 'gold standard' clinical assessment remains to be established.

    To identify the current management modalities practiced by neurosurgeons in India for chronic subdural hematoma. A questionnaire was prepared for the survey and sent via e-mail to neurosurgeons. It covered the following aspects of managing chronic subdural hematoma: 1) demographic and institutional details; 2) choice of surgical procedure; 3) surgical adjutants such as placing a subdural drain; 4) pre- and postoperative care; and 5) recurrences and management. Responses obtained were entered in a SPSS data sheet and analyzed. Response rate of the survey was 9.3%. The majority of neurosurgeons (75%) preferred to do burr whole drainage for primary chronic subdural hematoma and also for recurrences. Only one third of routinely placed a subdural drain. Considerable practice variations exist for medical and perioperative management. Bedside twist drill drainage, which is effective and less costly than operative room procedures, has not gained popularity in practice. The present survey points towards the importance of making management guidelines for this common neurosurgical entity. Copyright © 2016 Elsevier Inc. All rights reserved.

  11. Problem-based writing with peer review improves academic performance in physiology.

    Pelaez, Nancy J

    2002-12-01

    The aim of this study was to determine whether problem-based writing with peer review (PW-PR) improves undergraduate student performance on physiology exams. Didactic lectures were replaced with assignments to give students practice explaining their reasoning while solving qualitative problems, thus transferring the responsibility for abstraction and generalization to the students. Performance on exam items about concepts taught using PW-PR was compared with performance on concepts taught using didactic lectures followed by group work. Calibrated Peer Review, a Web-delivered program, was used to collect student essays and to manage anonymous peer review after students "passed" three calibration peer reviews. Results show that the students had difficulty relating concepts. Relationship errors were categorized as (1) problems recognizing levels of organization, (2) problems with cause/effect, and (3) overgeneralizations. For example, some described cells as molecules; others thought that vesicles transport materials through the extracellular fluid. With PW-PR, class discussion was used to confront and resolve such difficulties. Both multiple-choice and essay exam results were better with PW-PR instead of lecture.

    The use of plant or plant-based products to stimulate sexual desire and to enhance performance and enjoyment is almost as old as the human race itself. The present paper reviews the active, natural principles, and crude extracts of plants, which have been useful in sexual disorders, have potential for improving sexual behaviour and performance, and are helpful in spermatogenesis and reproduction. Review of refereed journals and scientific literature available in electronic databases and traditional literature available in India was extensively performed. The work reviews correlation of the evidence with traditional claims, elucidation, and evaluation of a plausible concept governing the usage of plants as aphrodisiac in total. Phytoconstituents with known structures have been classified in appropriate chemical groups and the active crude extracts have been tabulated. Data on their pharmacological activity, mechanism of action, and toxicity are reported. The present review provides an overview of the herbs and their active molecule with claims for improvement of sexual behaviour. A number of herbal drugs have been validated for their effect on sexual behavior and fertility and can therefore serve as basis for the identification of new chemical leads useful in sexual and erectile dysfunction.

  13. A systematic review of the effect of breakfast on the cognitive performance of children and adolescents.

    Hoyland, Alexa; Dye, Louise; Lawton, Clare L

    2009-12-01

    Breakfast is recommended as part of a healthy diet because it is associated with healthier macro- and micronutrient intakes, BMI and lifestyle. Breakfast is also widely promoted to improve cognitive function and academic performance, leading to the provision of breakfast initiatives by public health bodies. Despite this positive and intuitive perception of cognitive benefits, there has been no systematic review of the evidence. Systematic review methodology was employed to evaluate the effects of breakfast on cognitive performance in well-nourished children and nutritionally at-risk or stunted children. Acute experimental studies, school feeding programmes and studies of habitual breakfast intake are reviewed. Comparisons of breakfast v. no breakfast and breakfasts differing in energy and macronutrient composition are discussed. Included are forty-five studies described in forty-one papers published between 1950 and 2008. The evidence indicates that breakfast consumption is more beneficial than skipping breakfast, but this effect is more apparent in children whose nutritional status is compromised. There is a lack of research comparing breakfast type, precluding recommendations for the size and composition of an optimal breakfast for children's cognitive function. Few studies examined adolescents. Studies of school breakfast programmes suggest that such interventions can have positive effects on academic performance, but this may be in part explained by the increased school attendance that programmes encourage. The present systematic review considers methodological issues in this field and makes recommendations for future research design and policy priorities.

    The following literature review addresses the effects of various stressors on cognition. While attempting to be as inclusive as possible, the review focuses its examination on the relationships between cognitive appraisal, attention, memory, and stress as they relate to information processing and human performance. The review begins with an overview of constructs and theoretical perspectives followed by an examination of effects across attention, memory, perceptual-motor functions, judgment and decision making, putative stressors such as workload, thermals, noise, and fatigue and closes with a discussion of moderating variables and related topics. In summation of the review, a conceptual framework for cognitive process under stress has been assembled. As one might imagine, the research literature that addresses stress, theories governing its effects on human performance, and experimental evidence that supports these notions is large and diverse. In attempting to organize and synthesize this body of work, I was guided by several earlier efforts (Bourne & Yaroush, 2003; Driskell, Mullen, Johnson, Hughes, & Batchelor, 1992; Driskell & Salas, 1996; Haridcock & Desmond, 2001; Stokes & Kite, 1994). These authors should be credited with accomplishing the monumental task of providing focused reviews in this area and their collective efforts laid the foundation for this present review. Similarly, the format of this review has been designed in accordance with these previous exemplars. However, each of these previous efforts either simply reported general findings, without sufficient experimental illustration, or narrowed their scope of investigation to the extent that the breadth of such findings remained hidden from the reader. Moreover, none of these examinations yielded an architecture that adequately describes or explains the inter-relations between information processing elements under stress conditions.

    Many musicians experience debilitating music performance anxiety (MPA). Outside music performance, imagery-based interventions have been incorporated into treatment protocols to help individuals, including athletes and those with social anxiety, manage heightened levels of anxiety in order to excel in performance-based domains. Despite the frequent use of mental imagery in MPA interventions and its importance as a mental rehearsal technique for musicians, no existing reviews have examined the literature on imagery-based interventions for MPA. The primary aim of this review was to analyze the existing MPA literature in order to summarize what is known about the efficacy and mechanisms of pre-performance mental imagery exercises. A literature search yielded eight studies that used imagery-based interventions for MPA, in both student and professional musicians, which included three dissertations and five peer-reviewed journal articles. In extant MPA treatment research, pre-performance imagery is often used in conjunction with other techniques in order to alleviate anxiety. Arousal imagery refers to imagining one's state of arousal during performance and has been incorporated into MPA interventions in various ways that guide musicians to anticipate the heightened arousal that accompanies performance, predominantly through imagery-based relaxation techniques. However, methodological limitations make it impossible to determine whether imagery is itself an active ingredient of treatment that underlies symptom changes, or whether relaxation imagery is the most effective use of pre-performance imagery for all musicians. There is much need for future well-controlled studies to examine whether and how imagery affects MPA independent of the other therapy components and techniques with which it is commonly combined.

    The purpose of this study was to perform a systematic review to determine if respiratory muscle training (RMT) improves sport performance and respiratory muscle strength and endurance. Methodology followed the Cochrane Collaboration protocol. MEDLINE, CINAHL, SPORTDiscus, PEDro, EMBASE, EBM reviews, and COCHRANE electronic databases were searched until July 2011. Articles were included if: (a) participants were athletes; (b) RMT was compared with sham or control in a randomized controlled design and included outcomes of respiratory muscle and sport performance; and (d) published in English. Quality assessment using PEDro and data abstraction was performed by 2 authors. Outcomes evaluated were measures of sport performance, exercise capacity, spirometry, and respiratory muscle strength and endurance. Meta-analyses were performed on outcomes reported in 2 or more papers. Results of this systematic review revealed that of the 6,923 citations retrieved from the search strategy, 21 met the inclusion criteria. Meta-analyses demonstrated a significant positive effect of RMT on sport performance outcomes of time trials, exercise endurance time, and repetitions on Yo-Yo tests. Inspiratory muscle strength and endurance improved in most studies, which in part, was dependent on the type of RMT employed. Determination of the type of athlete that may benefit most from RMT was limited by small sample sizes, differing RMT protocols, and differences in outcome measures across studies. In conclusion, RMT can improve sport performance. Closer attention to matching the ventilatory demands of RMT to those required during athletic competition and more aggressive progression of training intensity may show greater improvements in future studies.

    A literature review and assessment was conducted by Pacific Northwest National Laboratory (PNNL) to update information on plant and animal radionuclide transfer factors used in performance-assessment modeling. A group of 15 radionuclides was included in this review and assessment. The review is composed of four main sections, not including the Introduction. Section 2.0 provides a review of the critically important issue of physicochemical speciation and geochemistry of the radionuclides in natural soil-water systems as it relates to the bioavailability of the radionuclides. Section 3.0 provides an updated review of the parameters of importance in the uptake of radionuclides by plants, including root uptake via the soil-groundwater system and foliar uptake due to overhead irrigation. Section 3.0 also provides a compilation of concentration ratios (CRs) for soil-to-plant uptake for the 15 selected radionuclides. Section 4.0 provides an updated review on radionuclide uptake data for animal products related to absorption, homeostatic control, approach to equilibration, chemical and physical form, diet, and age. Compiled transfer coefficients are provided for cow’s milk, sheep’s milk, goat’s milk, beef, goat meat, pork, poultry, and eggs. Section 5.0 discusses the use of transfer coefficients in soil, plant, and animal modeling using regulatory models for evaluating radioactive waste disposal or decommissioned sites. Each section makes specific suggestions for future research in its area.

    This review describes the most important factors affecting military work performance while wearing a CB mask: (1) the additional inspiratory and expiratory breathing resistance; (2) increased external dead space; (3) thermal stress of the mask and hood; (4) restriction of functional vision; (5) hindrance of speech transmission and reception; (6) weight, size, and pressure on the face by the CB mask; (7) claustrophobic reactions, and (8) sleep loss and lack of nutrient intake due to long-term wear. In assessing the biomedical aspects of these factors, rather than making comparisons between specific models of CB masks, the review addresses these factors as they apply to CB masks in general.

    We present a spectroscopic survey of galaxies in the COSMOS field using the Fiber Multi-object Spectrograph (FMOS), a near-infrared instrument on the Subaru Telescope. Our survey is specifically designed to detect the Hα emission line that falls within the H-band (1.6–1.8 μm) spectroscopic window from star-forming galaxies with 1.4 < z < 1.7 and M{sub stellar} ≳ 10{sup 10} M{sub ⊙}. With the high multiplex capability of FMOS, it is now feasible to construct samples of over 1000 galaxies having spectroscopic redshifts at epochs that were previously challenging. The high-resolution mode (R ∼ 2600) effectively separates Hα and [N ii]λ6585, thus enabling studies of the gas-phase metallicity and photoionization state of the interstellar medium. The primary aim of our program is to establish how star formation depends on stellar mass and environment, both recognized as drivers of galaxy evolution at lower redshifts. In addition to the main galaxy sample, our target selection places priority on those detected in the far-infrared by Herschel/PACS to assess the level of obscured star formation and investigate, in detail, outliers from the star formation rate (SFR)—stellar mass relation. Galaxies with Hα detections are followed up with FMOS observations at shorter wavelengths using the J-long (1.11–1.35 μm) grating to detect Hβ and [O iii]λ5008 which provides an assessment of the extinction required to measure SFRs not hampered by dust, and an indication of embedded active galactic nuclei. With 460 redshifts measured from 1153 spectra, we assess the performance of the instrument with respect to achieving our goals, discuss inherent biases in the sample, and detail the emission-line properties. Our higher-level data products, including catalogs and spectra, are available to the community.

  20. Music performance anxiety--part 1. A review of its epidemiology.

    2011-06-01

    Music performance anxiety (MPA) affects many individuals regardless of age, gender, experience, and hours of practice. In order to better understand the epidemiology of MPA, a review of the literature was done. Sixteen articles, meeting EBM criteria, were identified and analyzed. Children rarely suffer from MPA, while adolescents show symptoms similar to adults. Females are generally more affected than males. There is no relation between professional experience and performance anxiety. Great musicians such as Pau Casals and Enrico Caruso suffered from MPA. Nevertheless, students affected by MPA may decide not to become professional musicians because of their inability to cope with the devastating effects of performance anxiety. Solo performances showed higher MPA scores than ensemble performances. Despite these conclusions, long-term cohort studies with larger, homogeneous groups of subjects would be desirable, according to the evidence-based medicine criteria.

    With the increased use of digital systems in Nuclear Power Plant (NPP) control rooms comes a need to thoroughly understand the human performance issues associated with digital systems. A common way to evaluate human performance is to test operators and crews in NPP control room simulators. However, it is often challenging to characterize human performance in meaningful ways when measuring performance in NPP control room simulations. A review of the literature in NPP simulator studies reveals a variety of ways to measure human performance in NPP control room simulations including direct observation, automated computer logging, recordings from physiological equipment, self-report techniques, protocol analysis and structured debriefs, and application of model-based evaluation. These methods and the particular measures used are summarized and evaluated.

    To investigate the association between tertiary reviewer (admissions committee member) comments and medical students' performance during medical school and into internship. We collected data from seven year-groups (1993-1999) and coded tertiary reviewer comments into 14 themes. We then conducted an exploratory factor analysis to reduce the dimensions of the themes (excluding the Overall impression theme). Subsequently, we performed Pearson correlation analyses and multiple linear regression analysis to examine the relationship between the factors and seven outcome measures: medical school preclinical grade point average (GPA), medical school clinical GPA, cumulative medical school GPA, U.S. Medical Licensing Examination Step 1 and 2 scores, and scores on a program director's evaluation measuring intern professionalism and expertise. We extracted seven factors from the 13 themes and found small-to-moderate, significant correlations between the factors, the Overall impression theme, and the outcome measures. In particular, positive comments on Test and Maturity were associated with higher U.S. Medical Licensing Examination Step 1 and 2 scores. Negative comments on Interview and Recommendations were associated with lower ratings of professionalism during internship. Comments on Overall impression were significantly associated with all the outcome measures. Tertiary reviewer comments were weakly associated with performance in medical school and internship. Compared with positive comments, negative comments had stronger associations with medical school and internship performance measures.

    TQM is a management philosophy embracing all activities through which the needs and expectations of the customer and the community and the goals of the companies are satisfied in the most efficient and cost effective way by maximizing the potential of all workers in a continuing drive for total quality improvement. TQM is very important to the company especially in automotive industry in order for them to survive in the competitive global market. The main objective of this study is to review a relationship between TQM and employee performance. Authors review updated literature on TQM study with two main targets: (a) evolution of TQM considering as a set of practice, (b) and its impacts to employee performance. Therefore, two research questions are proposed in order to review TQM constructs and employee performance measure: (a) Is the set of critical success factors associated with TQM valid as a whole? (b) What is the critical success factors should be considered to measure employee performance in automotive industry?

    The concept of warming-up before a performance has been accepted across many disciplines including sports and music. In contrast, it is uncommon for a surgeon to "warm-up" prior to operating. To date, few studies from various specialties have attempted to answer this question whether warm-up improved the intraoperative performance of the surgeon. However, there has not been a systematic review of these studies. The aim of our systematic review is to assess the effect of warming-up preoperatively on the laparoscopic performance of the surgeon. Pubmed and scopus were searched to identify all published prospective observational studies, which involved either residents, fellows or attending surgeons. We excluded case reports, reviews, non-English studies, and medical student participation. Study risk of bias were assessed regarding sequence generation, allocation concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases, using a validated Cochrane Collaboration's tool. Out of 241 studies, 6 met the inclusion criteria. All included studies were randomized with half of them being randomized controlled studies and the rest randomized crossover studies. The total number of operative cases was 196, including 98 warm-up and 98 non warm-up. The total number of participants was 87, with the largest number in a single study being 38 and the average sample size of all studies was 14. All six studies assessed various aspects of laparoscopic surgical performances. Significant improvement in the intraoperative laparoscopic performance was observed with warming-up preoperatively in five out of six studies (p 0.05). Warming-up before an operative procedure improve a trainee's technical, cognitive, and psychomotor performance. Further studies are necessary to assess the ways in which warm-up could impact a surgeon's performance, and to identify the optimal timing and duration of warm-up prior to operating.

    A survey regarding general management, sire selection, reproductive management, inseminator training and technique, heat abatement, body condition scoring, facility design and grouping, nutrition, employee training and management, and animal health and bio-security was carried out from March to September of 2004 in 153 herds in the Alta Genetics (Watertown, WI) Advantage Progeny Testing Program. A total of 103 herds (67.3%) completed the survey. Herd size was 613 +/- 46 cows, with herds located in Wisconsin (26), California (12), New York (11), Minnesota (10), Michigan (7), Washington (6), Pennsylvania (6), Iowa (5), Idaho (5), Texas (4), Ohio (4), and other states (7). These farms sold 34.5 +/- 0.3 kg of milk/d per cow, with an annual culling rate of 34 +/- 1% and a calving interval of 13.8 +/- 0.1 mo. Cows were observed for estrus 2.8 +/- 0.3 times/d, for a duration of 27 +/- 4 min, but 78% of the respondents admitted that detection of estrus was not the employee's sole responsibility at that time. Managers tried to achieve pregnancy until 8.8 +/- 0.9 failed inseminations, 300 +/- 26 d postpartum, or milk yield cows were culled at 326 +/- 36 d postpartum or milk yield cows, respectively. Hormonal synchronization or timed artificial insemination programs were used in 87% of the herds, with 86% synchronizing first services, 77% resynchronizing repeat services, and 59% treating cystic, anestrous, or anovular cows. Finding good employees was identified as the greatest labor challenge, followed by training and supervising employees. Mastitis and hairy heel warts were noted as the greatest animal health concerns, followed by lameness, abortions, and death losses, whereas the greatest reproductive challenges were artificial insemination service rate, conception rate, twinning, and retained placenta or metritis. Results of this study can provide a useful benchmark or reference with regard to commonly used management practices on large commercial US dairy farms at the

    Purpose. The aim of this paper is to review the published studies on the characteristics of impairments in the postural control and gait performance in diabetic peripheral neuropathy (DPN). Methods. A review was performed by obtaining publication of all papers reporting on the postural control and gait performance in DPN from Google Scholar, Ovid, SAGE, Springerlink, Science Direct (SD), EBSCO Discovery Service, and Web of Science databases. The keywords used for searching were "postural control," "balance," "gait performance," "diabetes mellitus," and "diabetic peripheral neuropathy." Results. Total of 4,337 studies were hit in the search. 1,524 studies were screened on their titles and citations. Then, 79 studies were screened on their abstract. Only 38 studies were eligible to be selected: 17 studies on postural control and 21 studies on the gait performance. Most previous researches were found to have strong evidence of postural control impairments and noticeable gait deficits in DPN. Deterioration of somatosensory, visual, and vestibular systems with the pathologic condition of diabetes on cognitive impairment causes further instability of postural and gait performance in DPN. Conclusions. Postural instability and gait imbalance in DPN may contribute to high risk of fall incidence, especially in the geriatric population. Thus, further works are crucial to highlight this fact in the hospital based and community adults.

  10. Treatment of music performance anxiety via psychological approaches: a review of selected CBT and psychodynamic literature.

    Nagel, Julie J

    2010-12-01

    Performance anxiety, or stage fright, is anxiety aroused about potential mishaps in performance that expose feared inadequacies before an audience and which evoke feelings of embarrassment and humilation. For affected musicians, performance anxiety can be emotionally devastating, as their career choice in music may be terminated or severely compromised. This paper focuses on the cognitive and psychodynamic literature about music performance anxiety, with the emphasis that for treatment "one size does not fit all." It reviews the factors underlying performance anxiety and those factors which can exacerbate the condition in musicians. The two major clinical treatment modalities within contemporary psychology, cognitive behavior therapy (CBT) and psychodynamic treatments, are reviewed. While there are more empirical studies of CBT in various populations in the literature, until recently there was an indifference to empirical research by psychodynamic investigators. However, meta-analyses show strong efficacy for psychodynamic psychotherapy (in various disorders, not specifically music performance anxiety), but also that the benefits of psychodynamic psychotherapy may endure longer and increase with time.

    Several surveys have been administered over the last 40 plus years to learn about capital budgeting practices of healthcare organizations. In this report, we analyze and synthesize these surveys in a four-stage framework of the capital budgeting process: identification, development, selections, and post-audit. We examine three issues in particular: (1) efficiency of for-profit hospitals relative to not-for-profit hospitals, (2) capital budgeting practices of the healthcare industry vis-à-vis other industries, and (3) effects of healthcare mergers and acquisitions on capital budgeting decisions. We found indirect evidence that for-profit hospitals exhibited greater efficiency than not-for-profit hospitals in recent years. The acquisition of not-for-profits by for-profits is credited as the primary reason for growth of multihospital systems; these acquisitions may have contributed to the more efficient capital budgeting practices. One unique attribute of healthcare is the dominant role of physicians in almost all aspects of the capital budgeting process. In agreement with some researchers, we conclude that the disproportionate influence of physicians is likely to impede efficient decision making in capital budgeting, especially for nonprofit organizations.

  12. REVIEW OF MECHANISTIC UNDERSTANDING AND MODELING AND UNCERTAINTY ANALYSIS METHODS FOR PREDICTING CEMENTITIOUS BARRIER PERFORMANCE

    2009-11-30

    Cementitious barriers for nuclear applications are one of the primary controls for preventing or limiting radionuclide release into the environment. At the present time, performance and risk assessments do not fully incorporate the effectiveness of engineered barriers because the processes that influence performance are coupled and complicated. Better understanding the behavior of cementitious barriers is necessary to evaluate and improve the design of materials and structures used for radioactive waste containment, life extension of current nuclear facilities, and design of future nuclear facilities, including those needed for nuclear fuel storage and processing, nuclear power production and waste management. The focus of the Cementitious Barriers Partnership (CBP) literature review is to document the current level of knowledge with respect to: (1) mechanisms and processes that directly influence the performance of cementitious materials (2) methodologies for modeling the performance of these mechanisms and processes and (3) approaches to addressing and quantifying uncertainties associated with performance predictions. This will serve as an important reference document for the professional community responsible for the design and performance assessment of cementitious materials in nuclear applications. This review also provides a multi-disciplinary foundation for identification, research, development and demonstration of improvements in conceptual understanding, measurements and performance modeling that would be lead to significant reductions in the uncertainties and improved confidence in the estimating the long-term performance of cementitious materials in nuclear applications. This report identifies: (1) technology gaps that may be filled by the CBP project and also (2) information and computational methods that are in currently being applied in related fields but have not yet been incorporated into performance assessments of cementitious barriers.

    2013-05-01

    The aim of this paper was to review traditional approaches to habilitation of unilateral hearing losses as well as new research concerning management of unilateral hearing loss. Literature review/systematic review. A PubMed search was performed for articles pertaining to unilateral hearing loss and academic loss and academic performance. Articles ranged in date from 1986 to 2012. Five resources were reviewed for content to determine the pertinence of the materials to the understanding of the history of diagnosis of unilateral hearing loss, the traditional treatment methods and their advantages and disadvantages, and more recent publications concerning academic outcomes for patients with unilateral hearing loss with and without treatment. Unilateral hearing loss scan be detrimental to the academic success of children. Effects encompass not only auditory effects such as difficulty hearing in noise, but also self esteem and exhaustion. Although assistive devices were traditionally not offered as options, more recent literature suggests that devices such as BAHA, hearing aids, or FM systems may provide aids in the classroom and that early intervention may provide more favorable outcomes. Since the 1980s, the approach to management of unilateral hearing losses has evolved. In order to maximize academic potential, treatment options should be discussed and implemented. Copyright © 2013.

    Haemodynamic monitoring with transpulmonary thermodilution (TPTD) is less invasive than a pulmonary artery catheter, and is increasingly used in the Intensive Care Unit and the Operating Room. Optimal treatment of the critically ill patient demands adequate, precise and continuous monitoring of clinical parameters. Little is known about staff knowledge of the basic principles and practical implementation of TPTD measurements at the bedside. The aims of this review are to: 1) present the results of a survey on the knowledge of TPTD measurement among 252 nurses and doctors; and 2) to focus on specific situations and common pitfalls in order to improve patient management in daily practice. Web-based survey on knowledge of PiCCO technology (Pulsion Medical Systems, Feldkirchen, Germany), followed by PubMed and Medline search with review of the relevant literature regarding the use of TPTD in specific situations. In total, 252 persons participated in the survey: 196 nurses (78%) and 56 medical doctors (22%) of whom 17 were residents in training. Knowledge on the use of TPTD appears to be suboptimal, with an average score of 58.3%. Doctors performed better than nurses (62.7% vs 57.0%, P = 0.012). About 190 out of 252 (75.4%) scored at least 50% but only 45 respondents (17.9%) obtained a score of 70% or more. Having five years of PiCCO experience was present in 15.8% of the participants and this was correlated to passing the test, defined as obtaining a test result of ≥ 50% (P = 0.07) or obtaining a test result of ≥ 70% (P = 0.05). There were no other parameters significantly predictive for obtaining a result above 50% or above 70% such as gender or doctor versus nurse or Belgian versus Dutch residency, or years of ICU experience. High quality education of nursing and medical staff is necessary to perform the technique correctly and to analyse and interpret the information that can be obtained. Visual inspection of thermodilution curves is important as this can point

    U.S. Department of Energy (DOE) High Performance Computing (HPC) facilities are on the verge of a paradigm shift in the way they deliver systems and services to science and engineering teams. Research projects are producing a wide variety of data at unprecedented scale and level of complexity, with community-specific services that are part of the data collection and analysis workflow. On June 18-19, 2014 representatives from six DOE HPC centers met in Oakland, CA at the DOE High Performance Operational Review (HPCOR) to discuss how they can best provide facilities and services to enable large-scale data-driven scientific discovery at the DOE national laboratories. The report contains findings from that review.

  18. Effect of Geometric Modifications on the Performance of Vortex Tube - A Review

    Full Text Available The vortex tube is device, which produces hot and cold air streams simultaneously at its two ends from a source of compressed air without any moving part. Literature review of this paper is to understand the effect of various parameters like inlet pressure of air, number of nozzles, cold orifice diameter and hot end valve angle on the performance of vortex tube. Also by the literature review it is clear that there is no theory so perfect, which gives the satisfactory explanation of the vortex tube phenomenon. Due to this reason researcher conduct the series of experimentation to understand the effect of various parameters mentioned above on the performance of vortex tube.

    Core stability training, operationally defined as training focused to improve trunk and hip control, is an integral part of athletic development, yet little is known about its direct relation to athletic performance. This systematic review focuses on identification of the association between core stability and sports-related performance measures. A secondary objective was to identify difficulties encountered when trying to train core stability with the goal of improving athletic performance. A systematic search was employed to capture all articles related to athletic performance and core stability training that were identified using the electronic databases MEDLINE, CINAHL and SPORTDiscus™ (1982-June 2011). A systematic approach was used to evaluate 179 articles identified for initial review. Studies that performed an intervention targeted toward the core and measured an outcome related to athletic or sport performances were included, while studies with a participant population aged 65 years or older were excluded. Twenty-four in total met the inclusionary criteria for review. Studies were evaluated using the Physical Therapy Evidence Database (PEDro) scale. The 24 articles were separated into three groups, general performance (n = 8), lower extremity (n = 10) and upper extremity (n = 6), for ease of discussion. In the majority of studies, core stability training was utilized in conjunction with more comprehensive exercise programmes. As such, many studies saw improvements in skills of general strengths such as maximum squat load and vertical leap. Surprisingly, not all studies reported measurable increases in specific core strength and stability measures following training. Additionally, investigations that targeted the core as the primary goal for improved outcome of training had mixed results. Core stability is rarely the sole component of an athletic development programme, making it difficult to directly isolate its affect on athletic performance

    The purpose of this systematic review was to search the scientific literature for original research, addressing the effects different forms of resistance-based training have on sprinting performance in competitive sprinters. Specific key words (Sprinters OR Sprint) NOT (Rugby, Soccer, Cycling, Swimming, Paralympic, and Nutrition) were used to search relevant databases through November 2013 for related literature. Original research was reviewed using the Physiotherapy Evidence Database scale. Five studies met the inclusion criteria: actively competitive adult male sprinters who participated in a resistance-based intervention (>4 weeks), with outcome measures in the form of 10- to 100-m sprint times. Exclusion criteria included acute studies (100-m sprint times). Three of the 5 studies used both locomotor resistance and fixed plane resistance, whereas the remaining 2 studies used more fixed plane resistance, for example, squat and leg extension. Three of the studies showed a statistical improvement in sprinting performance measures, for example, a decrease in 30-m sprint time (p = 0.044), whereas 1 study showed a decrease in sprinting performance. The analysis concluded that resistance-based training has a positive effect on sprinting performance. Varied input of locomotor resistance and fixed plane resistance has resulted in similar percentage change for sprinting performance. This review adds to the body of knowledge by strongly highlighting the dearth of literature exploring the effects of resistance-based training on sprinting performance in competitive sprinters. The short duration and wide range of exercises implemented in studies to date are of concern, but coaches should not hesitate to implement well-planned resistance programs for their sprint athletes.
