A Review of the Relationships among the Key Determinants Affecting the Mental Health Disorders of the People in Greater Mekong Subregion Countries

PubMed Central

Nget, Manndy; Muijeen, Kasorn

2017-01-01

Background: ASEAN integration aims to transform the GMS into a single market with free flows of products, services, and skilled labor, as well as investment openness, which will ultimately force regional economic growth. Therefore, this integration is likely to bring about a big change to this area in the new era; it can subsequently cause many problems as well, including mental health issues of the people in this region. The characteristic differences among the GMS member countries in terms of trade and investment, social and cultural values, medical information and technology, and the living and working environment have become major problems affecting mental health disorders, which are usually identified as depression, stress, and substance abuse. Methods: This review paper is a literature review of the relationship of the determinants affecting GMS mental disorders conducted using the following strategies: 1) collecting data from previous qualitative and quantitative research studies, comparatively analyzing the literature, articles, published papers, and reports relevant to the existing policies on economic, environmental, and healthcare issues obtained from the GMS; and 2) exchanging information from the institutions involved, including reports and papers regarding the determinants affecting mental health disorders of the people in the GMS, which were used to generate the synthesis of the existing knowledge of the mental health and to provide recommendation programs for the GMS people. Results: Based on the reviewed literature there are four key factors affecting mental health, especially mental health in GMS populations: 1) the living and work environments; 2) trade and investment; 3) technology and medical information; and 4) social and cultural values. The study found that the increasing number of mental health disorders is a big burden for national healthcare spending. Financial issues have become a major key to the wide prevalence of mental disorders in the GMS. Health issues related to mental health disorders are also caused by the environment and other related factors and therefore a stable and a well-balanced environment is an indicator of healthy mental status. In addition, the environment is a way to pursue both physical and mental health because green spaces serve as a mood freshener and can alleviate anxiety, stress, and depression. Conclusion: Globalization and urbanization should follow sustainable development instructions and concerns about the population’s health, especially regarding mental health. These key determinants affect the people’s life, especially in terms of mental health thus leading to mental health disorders. PMID:29527146

Health professionals publishing within the field of health sciences continue to experience issues concerning appropriate authorship, which have clinical, ethical, and academic implications. This integrative review sought to explore the key issues concerning authorship from a bioethical standpoint, aiming to explore the key features of the authorship debate. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus databases of peer-reviewed research, published between 2009 and 2014, limited to English language research, with search terms developed to reflect the current issues of authorship. From among the 279 papers identified, 20 research papers met the inclusion criteria. Findings were compiled and then arranged to identify themes and relationships. The review incorporated a wide range of authorship issues encompassing equal-credited authors, honorary (guest/gift) and ghost authorship, perception/experiences of authorship, and guidelines/policies. This review suggests that the International Committee of Medical Journal Editors’ (ICMJE) recommended guidelines for authorship are not reflected in current authorship practices within the domain of health sciences in both low-and high-impact-factor journals. This devaluing of the true importance of authorship has the potential to affect the validity of authorship, diminish the real contributions of the true authors, and negatively affect patient care.

Safety issues and new rapid detection methods in traditional Chinese medicinal materials

PubMed Central

Wang, Lili; Kong, Weijun; Yang, Meihua; Han, Jianping; Chen, Shilin

2015-01-01

The safety of traditional Chinese medicine (TCM) is a major strategic issue that involves human health. With the continuous improvement in disease prevention and treatment, the export of TCM and its related products has increased dramatically in China. However, the frequent safety issues of Chinese medicine have become the ‘bottleneck’ impeding the modernization of TCM. It was proved that mycotoxins seriously affect TCM safety; the pesticide residues of TCM are a key problem in TCM international trade; adulterants have also been detected, which is related to market circulation. These three factors have greatly affected TCM safety. In this study, fast, highly effective, economically-feasible and accurate detection methods concerning TCM safety issues were reviewed, especially on the authenticity, mycotoxins and pesticide residues of medicinal materials.

Music, affect, method, data: reflections on the Carroll versus Kivy debate.

PubMed

Konecni, Vladimir J

2013-01-01

The comprehensive exchange between Noel Carroll and Peter Kivy, which took place in 2007, addressed key issues in the relationship between music and affect. More than in any prior philosophical debate on this topic, experimental psychologists' methods and data played a significant role. However, to a nontrivial extent, the findings-perhaps especially the dubious-were misconstrued or misused, usually without acknowledging the existence of contrary data-based opinion within the psychology of music itself. Therefore, one objective of the present article is to identify the specific problematic features and shed light on the broader context shared by the two disciplines. A complementary goal is to examine contributions to philosophers' transgressions by music psychologists' insufficiently conscientious reporting, frequent overgeneralizations, and unawareness of philosophers' critical arguments. Another objective is to examine the current status of key concepts-the relevant music, basic emotions, mood, expression, induction, movement and dance, and methods (including introspection and experimental procedures)-thus perhaps enabling the discussion of music and affect to proceed with fewer misunderstandings. Finally, the article moves beyond the initial debate and builds on a remarkable agreement of philosophical and psychological opinion on a key issue (the induction of non-basic emotions by absolute music) to reach a new conceptual ground.

Measuring competition in health care markets.

Baker, L C

2001-01-01

OBJECTIVE: Measuring competition is increasingly important for analysis of health care markets and policies. Measurement of competition in health care is made complex by the breadth of potential issues under study, by the lack of necessary data, and by rapid changes in health care financing and delivery. This study reviews key issues in the measurement of competition and is designed to familiarize researchers and policymakers interested in competition measurement, but not steeped in its practice, with key concepts, data sources, and ways of adapting measures to fit ongoing changes in health care markets. PRINCIPAL FINDINGS: Attention to several key issues will strengthen measurement. Important components of successful measurement are: careful identification of the products and market areas for study; selection of Herfindahl-Hirschman or other indices to fit the issues being considered; consideration of econometric problems, like endogeneity, with common measures; and attention to the ways that current marketplace changes, like growth in managed care, affect the performance of classic measures. Data needed for constructing measures are also frequently scarce, insufficient, or both. Measurement could be improved with access to better data. PMID:11327175

Whelan, Jessica J; Willis, Karen

2007-01-01

Access to safe drinking water is essential to human life and wellbeing, and is a key public health issue. However, many communities in rural and regional parts of Australia are unable to access drinking water that meets national standards for protecting human health. The aim of this research was to identify the key issues in and barriers to the provision and management of safe drinking water in rural Tasmania, Australia. Semi-structured interviews were conducted with key local government employees and public health officials responsible for management of drinking water in rural Tasmania. Participants were asked about their core public health duties, regulatory responsibilities, perceptions and management of risk, as well as the key barriers that may be affecting the provision of safe drinking water. This research highlights the effect of rural locality on management and safety of fresh water in protecting public health. The key issues contributing to problems with drinking water provision and quality identified by participants included: poor and inadequate water supply infrastructure; lack of resources and staffing; inadequate catchment monitoring; and the effect of competing land uses, such as forestry, on water supply quality. This research raises issues of inequity in the provision of safe drinking water in rural communities. It highlights not only the increasing need for greater funding by state and commonwealth government for basic services such as drinking water, but also the importance of an holistic and integrated approach to managing drinking water resources in rural Tasmania.

We evaluated Management Questions (Core and Integrated) for each species and community for the Wyoming Basin REA. Core Management Questions address primary management issues, including (1) where is the Conservation Element, and what are its key ecological attributes (characteristics of species and communities that may affect their long-term persistence or viability); (2) what and where are the Change Agents; and (3) how do the Change Agents affect the key ecological attributes? Integrated Management Questions synthesize the Core Management Questions as follows: (1) where are the areas with high landscape-level ecological values; (2) where are the areas with high landscape-level risks; and (3) where are the potential areas for conservation, restoration, and development? The associated maps and key findings for each Management Question are summarized for each Conservation Element in individual chapters. Additional chapters on landscape intactness and an REA synthesis are included.

A national project investigated seniors' perceptions of the influences upon their quality of life. The seven participating cities were Montreal, Quebec City, Ottawa, Toronto, Regina, Vancouver and Whitehorse. The project focussed on policy decisions affecting the quality of life of seniors. It was a participatory study in which seniors controlled the direction and shape of the project in each city. Focus groups and individual interviews with seniors and stakeholders. Data analysis used qualitative methods to see the world through the eyes of participants. Each project was committed to hearing the voices of seniors and their views on which issues were affecting the quality of their lives. Across the seven cities, seniors highlighted access to information, health care, housing, income security, safety and security, social contacts and networks, and transportation as key issues that affect the quality of life of seniors in Canada. The findings affirm the value of participatory activities that involve seniors working with other sectors as a productive policy-informing approach. The Seniors' Quality of Life projects demonstrate the conceptual power of the determinants of health perspective to understand seniors' quality of life issues. While seniors considered health care to be a continuing concern, they also recognized socio-economic issues as significantly affecting the quality of their lives.

This study explores the way the publication of a National White Book on health and safety risks that affect workers in jobs involving Nanotechnologies and Nanomaterials influenced the key Italian stakeholders attitude toward this issue and identifies the standpoints and priorities shared among researchers and stakeholders to develop a policy framework to address this issue. The study not only highlights some important assumptions (i.e. the acknowledgment by the key stakeholders of the need for actions and the identification of objectives which can gain a wide consensus) for the establishment of a policy community that sustains the development of a policymaking process on the issue but, through the interaction between stakeholders and OSH researchers, it also identifies some in nuce proposals that represent the starting point for policy interventions aimed at meeting the needs of both stakeholders and scientific community. Results obtained in terms of clarification of interests at stake, identification of potential areas of consensus and level of key national actors' engagement achieved, show the potentialities of adopting a knowledge based and inclusive approach to policy-making to address the issue of prevention and management of health and safety risks related to technological innovation within a framework of scientific uncertainty.

Environmental Barrier Coatings for Ceramics and Ceramic Composites

NASA Technical Reports Server (NTRS)

Lee, Kang N.; Fox, Dennis; Eldridge, Jeffrey; Robinson, R. Craig; Bansal, Narottam

2004-01-01

One key factor that limits the performance of current gas turbine engines is the temperature capability of hot section structural components. Silicon-based ceramics, such as SiC/SiC composites and monolithic Si3N4, are leading candidates to replace superalloy hot section components in the next generation gas turbine engines due to their excellent high temperature properties. A major stumbling block to realizing Si-based ceramic hot section components is the recession of Si-based ceramics in combustion environments due to the volatilization of silica scale by water vapor. An external environmental barrier coating (EBC) is the most promising approach to preventing the recession. Current EBCs are based on silicon, mullite (3A12O3-2SiO2) and BSAS (barium strontium aluminum silicate with celsian structure). Volatility of BSAS, BSAS-silica chemical reaction, and low melting point of silicon limit the durability and temperature capability of current EBCs. Research is underway to develop EBCs with longer life and enhanced temperature capability. Understanding key issues affecting the performance of current EBCs is necessary for successful development of advanced EBCs. These issues include stress, chemical compatibility, adherence, and water vapor stability. Factors that affect stress are thermal expansion mismatch, phase stability, chemical stability, elastic modulus, etc. The current understanding on these issues will be discussed.

Taxation is a key instrument by which governments affect economic decision making and outcomes. Not surprisingly, energy taxation has received considerable attention in recent years with the mounting concern over national energy policy. As with other policy instruments, the taxation of energy production and use spans a wide array of topics. It also cuts across other instruments because it affects the entire spectrum of economic variables - prices, outputs, investments, uses, and so on. As a result, the subject of energy taxation constitutes a highly complex set of issues for public policy. This report examines the principal components of thatmore » set of issues. In the process, it points out the most-important interrelations among the various taxes and between taxation and other policy instruments.« less

Improvement of the performances of a tandem simulated moving bed chromatography by controlling the yield level of a key product of the first simulated moving bed unit.

PubMed

Mun, Sungyong; Wang, Nien-Hwa Linda

2017-03-10

One of the trustworthy processes for ternary separation is a tandem simulated moving bed (SMB) process, which consists of two subordinate four-zone SMB units (Ring I and Ring II). To take full advantage of a tandem SMB as a means of recovering all three products with high purities and high economical efficiency, it is important to understand how the separation condition in Ring II is affected by that in Ring I, and further to reflect such point in the stage of designing a tandem SMB. In regard to such issue, it was clarified in this study that the Ring I factors affecting the Ring II condition could be represented by the yield level of a key product of Ring I (Y key RingI ). As the Y key RingI level became higher, the amount of the Ring I key-product that was reloaded into Ring II was reduced, which affected favorably the Ring II separation condition. On the other hand, the higher Y key RingI level caused a larger dilution for the stream from Ring I to Ring II, which affected adversely the Ring II separation condition. As a result, a minimum in the desorbent usage of a tandem SMB occurred at the Y key RingI level where the two aforementioned factors could be balanced with each other. If such an optimal Y key RingI level was adopted, the desorbent usage could be reduced by up to 25%. It was also found that as the throughput of a tandem SMB became higher, the factor related to the migration of the Ring I key-product into Ring II was more influential in the performances of a tandem SMB than the factor related to the dilution of the stream from Ring I to Ring II.

Effect of culture on acceptance of telemedicine in Middle Eastern countries: case study of Jordan and Syria.

PubMed

Alajlani, Mohannad; Clarke, Malcolm

2013-04-01

We investigated issues that affect the use and adoption of telemedicine in Middle Eastern countries, taking the Hashemite Kingdom of Jordan and the Syrian Arab Republic as case studies. Our study is based on interviews with key stakeholders (including doctors, technicians, engineers, and decision makers) and questionnaires administered to key stakeholders (including patients), ensuring opinion was gained from people from a full range of backgrounds and roles in the healthcare system. We found doctor and patient resistance was a major issue preventing the adoption of telemedicine in both countries, followed by poor infrastructure, lack of funding, and lack of information technology training. Our research identifies that culture is a greater issue than technical matters for the adoption of telemedicine in Middle Eastern countries. Based on our preliminary results we developed a guideline framework for each country that might be applied to telemedicine projects at the pre-implementation phase. The proposed guideline framework was validated through a return visit to the stakeholders and seeking further opinion.

Life cycle assessment of lignocellulosic ethanol: a review of key factors and methods affecting calculated GHG emissions and energy use.

PubMed

Gerbrandt, Kelsey; Chu, Pei Lin; Simmonds, Allison; Mullins, Kimberley A; MacLean, Heather L; Griffin, W Michael; Saville, Bradley A

2016-04-01

Lignocellulosic ethanol has potential for lower life cycle greenhouse gas emissions compared to gasoline and conventional grain-based ethanol. Ethanol production 'pathways' need to meet economic and environmental goals. Numerous life cycle assessments of lignocellulosic ethanol have been published over the last 15 years, but gaps remain in understanding life cycle performance due to insufficient data, and model and methodological issues. We highlight key aspects of these issues, drawing on literature and a case study of corn stover ethanol. Challenges include the complexity of feedstock/ecosystems and market-mediated aspects and the short history of commercial lignocellulosic ethanol facilities, which collectively have led to uncertainty in GHG emissions estimates, and to debates on LCA methods and the role of uncertainty in decision making.

Need for "conflict version" of primary surgery: war surgery in the era of low-intensity conflicts.

PubMed

Morikawa, Masahiro J

2006-01-01

The conventional wars between nations have widely been replaced by low-intensity conflicts within nations today, resulting in different patterns of injuries and practice of surgical care. A blurred front line, protracted durations of violence, indiscriminant fighting, and the emergence of specific surgical problems characterize low-intensity conflicts. In protracted conflicts with limited resources, surgical outcomes depend on many factors other than surgical skills, such as social/cultural values and economical feasibility. This paper examines how the characteristics of current conflicts affect surgical practice and will address key issues to evolve care to adapt to these changes. Key issues are (1) need for comprehensive surgical skills, (2) importance of improving local capacities, (3) long-term impact of trauma, and (4) limited access to information required to improve surgical skills.

The corporate impact of addressing social issues: a financial case study of a project in Peru.

PubMed

Dabbs, Alan; Bateson, Matthew

2002-05-01

Large, multinational resource development projects can affect many aspects, including social, economic and ecological realities, in the regions where they operate. Social and environmental issues that are usually ignored in such projects are increasingly affecting the financial future of multinational corporations in negative ways. In this article, we advance the argument that corporations can successfully manage these issues and that if they choose to view these management efforts as an investment rather than an expense, they may well acquire a competitive advantage over companies that do not. We describe as a case study the Camisea natural gas and condensates development project in Peru, operated by Shell Prospecting and Development Peru (SPDP). Camisea is one of the first projects anywhere in the world to conduct a detailed analysis of key industry-related social issues and the processes, required investment and financial impact of managing them. The Camisea example supports the argument that addressing social and environmental concerns makes financial sense. In present value terms, the benefit of managing these concerns was expected to surpass the cost investment by approximately US$50 million.

Nursing management and organizational ethics in the intensive care unit.

PubMed

Wlody, Ginger Schafer

2007-02-01

This article describes organizational ethics issues involved in nursing management of an intensive care unit. The intensive care team and medical center management have the dual responsibility to create an ethical environment in which to provide optimum patient care. Addressing organizational ethics is key to creating that ethical environment in the intensive care unit. During the past 15-20 yrs, increasing costs in health care, competitive markets, the effect of high technology, and global business changes have set the stage for business and healthcare organizational conflicts that affect the ethical environment. Studies show that critical care nurses experience moral distress and are affected by the ethical climate of both the intensive care unit and the larger organization. Thus, nursing moral distress may result in problems related to recruitment and retention of staff. Other issues with organizational ethics ramifications that may occur in the intensive care unit include patient safety issues (including those related to disruptive behavior), intensive care unit leadership style, research ethics, allocation of resources, triage, and other economic issues. Current organizational ethics conflicts are discussed, a professional practice model is described, and multidisciplinary recommendations are put forth.

This research explored the perspectives of Malaysian professionals on the issues and barriers affecting the implementation of sexuality education in Malaysia. This qualitative study involved in-depth interviews with 15 key professionals working in the field of sexuality and reproductive health in Malaysia. Thematic analysis was selected to analyze data. Barriers to sexuality education were perceived from 5 aspects: feasibility, acceptability, accountability, strategies, and community unawareness. Respondents believed that implementing national sexuality education is a time-consuming project. They regarded Malaysian multicultural society as a barrier to national sexuality education, and they believed that school-based sexuality education is not easily accomplished in Malaysia; also abstinence-only policy restricts the access of young people to accurate information. Lack of community involvement was perceived as a key concern to sexuality education. Campaigning to promote awareness of families, teachers, community leaders, and policy makers are recommended to help establishing national sexuality education in Malaysia. © 2014 APJPH.

Exercise and multiple sclerosis: physiological, psychological, and quality of life issues.

PubMed

Sutherland, G; Andersen, M B

2001-12-01

The case for the benefits of physical activity has been well documented in healthy individuals, and the potential for reducing the risk of mental and physical ill health is substantial. Yet, individuals with multiple sclerosis (MS) have long been advised to avoid participation in exercise in order to minimise the risk of exacerbations and symptoms of fatigue. There is, however, increasing interest in how acute and chronic exercise affect physiological and psychological functioning in MS. Much of the research has examined physiological tolerance to exercise and focused on responses in terms of heart rate, blood pressure, cardiorespiratory fitness, muscle function, and symptom stability. Little research has focused on understanding how exercise affects psychosocial functioning and brings about changes in depression, affect, mood, well-being, and quality of life. This paper provides a summary of the research exploring the efficacy of physical activity for people with MS. In addition, the key issues that face clinical practice are examined, and considerations for research are discussed.

Strategic environmental noise mapping: methodological issues concerning the implementation of the EU Environmental Noise Directive and their policy implications.

Murphy, E; King, E A

2010-04-01

This paper explores methodological issues and policy implications concerning the implementation of the EU Environmental Noise Directive (END) across Member States. Methodologically, the paper focuses on two key thematic issues relevant to the Directive: (1) calculation methods and (2) mapping methods. For (1), the paper focuses, in particular, on how differing calculation methods influence noise prediction results as well as the value of the EU noise indicator L(den) and its associated implications for comparability of noise data across EU states. With regard to (2), emphasis is placed on identifying the issues affecting strategic noise mapping, estimating population exposure, noise action planning and dissemination of noise mapping results to the general public. The implication of these issues for future environmental noise policy is also examined. Copyright (c) 2009 Elsevier Ltd. All rights reserved.

GAIA - A New Approach To Decision Making on Climate Disruption Issues

2011-12-01

GAIA - the Global Assimilation of Information for Action program - provides a broadly extensible framework for enabling the development of a deeper understanding of the issues associated with climate disruption. The key notion of GAIA is that the global climate problem is so complex that a "system engineering" approach is needed in order to make it understandable. The key tenet of system engineering is to focus on requirements and to develop a cost-effective process for satisfying those requirements. To demonstrate this approach we focused first on the impact of climate disruption on public health. GAIA is described in some detail on our website (http://gaia.jhuapl.edu). Climate disruption is not just a scientific problem; one of the key issues that our community has is that of translating scientific results into knowledge that can be used to make informed decisions. In order to support decision makers we have to understand their issues and how to communicate with them. In this talk, we describe how we have built a community of interest that combines subject matter experts from diverse communities (public health, climate change, government, public policy, industry, etc) with policy makers and representatives from industry to develop, on a "level playing field", an understanding of each other's points of view and issues. The first application of this technology was the development of a workshop on Climate, Climate Change and Public Health held April 12-14, 2011. This paper describes our approach to going beyond the workshop environment to continue to engage the decision maker's community in a variety of ways that translate abstract scientific data into actionable information. Key ideas we will discuss include the development of social media, simulations of global/national/local environments affected by climate disruption, and visualizations of the monetary and health impacts of choosing not to address mitigation or adaptation to climate disruption.

2001-01-01

Background The massive growth of health information on the Internet; the global nature of the Internet; the seismic shift taking place in the relationships of various actors in this arena, and the absence of real protection from harm for citizens who use the Internet for health purposes are seen to be real problems. One response to many of these problems has been the burgeoning output of codes of conduct by numerous organizations trying to address quality of health information. Objectives Review the major self-regulatory initiatives in the English-speaking world to develop quality and ethical standards for health information on the Internet. Compare and analyze the approaches taken by the different initiatives. Clarify the issues around the development and enforcement of standards. Methods Quality initiatives selected meet one or more of the following criteria: Self-regulatory. A reasonable constituency. Diversity (eg, of philosophy, approach and process)-to achieve balance and wide representation, and to illustrate and compare different approaches. Historic value. A wider reach than a national audience, except when its reach is a significant sector of the Internet health information industry. The initiatives were compared in 3 ways: (1) Analysis and comparison of: key concepts, mechanism, or approach. Analysis of: the obligations that a provider has to meet to comply with the given initiative, the intended beneficiaries of that initiative, and the burdens imposed on different actors. These burdens are described in terms of their effect on the long-term sustainability and maintenance of the initiative by its developers. Analysis of the enforcement mechanisms. (2) Analysis and comparison by type of sponsoring organization, the reach of the initiative, and the sources of funding of the initiative or the sponsoring organization. (3) How the various initiatives fall under 1 of 3 key mechanisms and comparison of the advantages and disadvantages of these key mechanisms. Results The issues that affect the initiatives and future work on the quality of health information on the Internet are identified and analyzed. These issues are: (a) Three key mechanisms used in the quality initiatives (b) Sustainability issues that affect the initiatives: Burdens placed on health information providers, citizens and others. Currency and maintenance issues of the initiatives. Funding. Cost. Acceptance. Market conditions. User indifference or ambivalence. (c) Enforcement issues surrounding the initiatives (d) Adequacy of approach, scope, reach, and enforcement provisions of the various quality initiatives (e) Gaps that need to be addressed to achieve good quality of health information on the internet Conclusions Ten conclusions are presented. A framework of action to be undertaken by the World Health Organization in the field of quality of health information on the Internet is recommended. PMID:11772543

Children spend a lot of time watching television on its many platforms: directly, online, and via videos and DVDs. Many researchers are concerned that some types of television content appear to negatively influence children's executive function. Because (1) executive function predicts key developmental outcomes, (2) executive function appears to be influenced by some television content, and (3) American children watch large quantities of television (including the content of concern), the issues discussed here comprise a crucial public health issue. Further research is needed to reveal exactly what television content is implicated, what underlies television's effect on executive function, how long the effect lasts, and who is affected. © 2015 Elsevier Inc.

This paper assesses hypothesis that sufficient sleep duration and proper circadian rhythms during the early stages of life are indispensable to a successful life. Successful life was defined according to the famous cohort studies of Mischel's and Dunedin. To assess the hypothesis, neuronal elements presumably affecting early daily habits and successful life are reviewed. The effect of sufficient sleep duration and proper circadian rhythms during early stages of life on the development of the prefrontal cortex has been found to be the key issue to verify the hypothesis. Socioeconomic status is found to be another issue to be studied.

Novel Multi-Party Quantum Key Agreement Protocol with G-Like States and Bell States

NASA Astrophysics Data System (ADS)

Min, Shi-Qi; Chen, Hua-Ying; Gong, Li-Hua

2018-03-01

A significant aspect of quantum cryptography is quantum key agreement (QKA), which ensures the security of key agreement protocols by quantum information theory. The fairness of an absolute security multi-party quantum key agreement (MQKA) protocol demands that all participants can affect the protocol result equally so as to establish a shared key and that nobody can determine the shared key by himself/herself. We found that it is difficult for the existing multi-party quantum key agreement protocol to withstand the collusion attacks. Put differently, it is possible for several cooperated and untruthful participants to determine the final key without being detected. To address this issue, based on the entanglement swapping between G-like state and Bell states, a new multi-party quantum key agreement protocol is put forward. The proposed protocol makes full use of EPR pairs as quantum resources, and adopts Bell measurement and unitary operation to share a secret key. Besides, the proposed protocol is fair, secure and efficient without involving a third party quantum center. It demonstrates that the protocol is capable of protecting users' privacy and meeting the requirement of fairness. Moreover, it is feasible to carry out the protocol with existing technologies.

The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variations Contrary to pre-launch expectations, the image quality is continuously evolving, during commissioning and the nominal mission. Payload decontaminations and wavefront sensor assisted refocuses have been carried out to recover optimum performance. An ESA-Airbus DS working group analysed the straylight and basic angle issues and worked on a detailed root cause analysis. In parallel, the Gaia scientists have also analysed the data, most notably comparing the BAM signal to global astrometric solutions, with remarkable agreement. In this contribution, a status review of these issues will be provided, with emphasis on the mitigation schemes and the lessons learned for future space missions where extreme stability is a key requirement.

Yeow, Paul H P; Yuen, Y Y; Loo, W H

2013-09-01

Ever since the 9/11 terrorist attack, many countries are considering the use of smart national identity card (SNIC) which has the ability to identify terrorists due to its biometric verification function. However, there are many ergonomics issues in the use of SNIC, e.g. card credibility. This research presents a case study survey of Malaysian users. Although most citizens (>96%) own MyKad (Malaysia SNIC), many do not carry it around and use its applications. This defeats one of its main purposes, i.e. combating terrorism. Thus, the research investigates ergonomics issues affecting the citizens' Intention to Use (ITU) MyKad for homeland security by using an extended technology acceptance model. Five hundred questionnaires were collected and analysed using structural equation modelling. Results show that perceived credibility and performance expectancy are the key issues. The findings provide many countries with insights into methods of addressing ergonomics issues and increasing adoption of SNIC for homeland security.

Nowadays, the web increasingly influences retail sales. An in-depth analysis of consumer decision-making in the context of e-business has become an important issue for internet vendors. However, factors affecting e-business are complicated and intertwined. To stimulate online sales, understanding key influential factors and causal relationships among the factors is important. To gain more insights into this issue, this paper introduces a hybrid method, which combines the Decision Making Trial and Evaluation Laboratory (DEMATEL) with the analytic network process, called DANP method, to find out the driving factors that influence the online business mostly. By DEMATEL approach the causal graph showed that "online service" dimension has the highest degree of direct impact on other dimensions; thus, the internet vendor is suggested to made strong efforts on service quality throughout the online shopping process. In addition, the study adopted DANP to measure the importance of key factors, among which "transaction security" proves to be the most important criterion. Hence, transaction security should be treated with top priority to boost the online businesses. From our study with DANP approach, the comprehensive information can be visually detected so that the decision makers can spotlight on the root causes to develop effectual actions.

This paper is a synthesis of research on recruitment and retention challenges for home support workers (HSWs) in Canada. Home support workers (HSWs) provide needed support with personal care and daily activities to older persons living in the community. Literature (peer reviewed, government, and non-government documents) published in the past decade was collected from systematic data base searches between January and September 2009, and yielded over 100 references relevant to home care human resources for older Canadians. Four key human resource issues affecting HSWs were identified: compensation, education and training, quality assurance, and working conditions. To increase the workforce and retain skilled employees, employers can tailor their marketing strategies to specific groups, make improvements in work environment, and learn about what workers value and what attracts them to home support work. Understanding these HR issues for HSWs will improve recruitment and retention strategies for this workforce by helping agencies to target their limited resources. Given the projected increase in demand for these workers, preparations need to begin now and consider long-term strategies involving multiple policy areas, such as health and social care, employment, education, and immigration.

People living with HIV and key populations face human rights violations that affect their access to health services, relationships in their communities, housing options, and employment. To address these violations, government and civil society organizations in Ghana developed a discrimination reporting system managed by the Commission on Human Rights and Administrative Justice that links people living with HIV and key populations to legal services. This article presents findings on how Ghanaian stakeholders built this reporting system and discusses preliminary data on its impact. To organize our analysis, we used a conceptual framework that outlines the legal frameworks that protect human rights, the institutions that promote access to justice, and the mechanisms that link people living with HIV and key populations to legal services. Using in-depth interviews, we show that targeted technical assistance increased stakeholders' knowledge of issues that affect people living with HIV and key populations, strengthened these stakeholders' commitment to address discrimination, streamlined case management systems, and improved relationships between civil society and the government. Through case review, we find that most discrimination happens when accessing government services, inside communities and families, and in the workplace. Finally, we describe implications for other human rights commissions that are considering using a reporting system to protect human rights, including using legal frameworks, developing case management systems, and working with civil society.

2017-01-01

Amazon Mechanical Turk (MTurk) is becoming a prevalent source of quick and cost effective data for organizational research, but there are questions about the appropriateness of the platform for organizational research. To answer these questions, we conducted an integrative review based on 75 papers evaluating the MTurk platform and 250 MTurk samples used in organizational research. This integrative review provides four contributions: (1) we analyze the trends associated with the use of MTurk samples in organizational research; (2) we develop a systems perspective (recruitment system, selection system, and work management system) to synthesize and organize the key factors influencing data collected on MTurk that may affect generalizability and data quality; (3) within each factor, we also use available MTurk samples from the organizational literature to analyze key issues (e.g., sample characteristics, use of attention checks, payment); and (4) based on our review, we provide specific recommendations and a checklist for data reporting in order to improve data transparency and enable further research on this issue.

2014-01-01

Objectives To examine what factors influence the agenda-setting process and level of political priority afforded to micronutrient deficiencies (MNDs). Design Qualitative case study employing process tracing, informed by primary data collected from semistructured interviews with policymakers. Setting Dakar, Senegal. Results Several facilitating and impeding factors affecting the level of political prioritisation for MNDs were identified. Facilitating factors included multiple stakeholders using aligned framing to collectively advocate for MNDs; availability of indicators to quantify issue severity and raise awareness; and transnational advocacy activities around micronutrients. Impeding factors included lack of awareness among policymakers and civil society about MNDs; issue complexity, with the need for coordinated multisectoral response to deliver a complex package of solutions; lack of resources trapping the issue in a ‘low-priority’ cycle; lack of a policy champion to advocate for the issue and the challenge of demonstrating the effectiveness of interventions to support advocacy efforts. Conclusions This study gives insight into the political prioritisation process for MNDs from the perspective of key stakeholders working at the national level in Senegal. In doing so, the study offers some explanation as to why the issue of MNDs has struggled to gain political attention and make it onto the national policy agenda. Moving forward, greater awareness of the factors affecting agenda setting for MNDs may help to devise political strategies to champion this development issue in countries with high burdens of micronutrient deficiencies.

2015-05-13

Crohn's disease is a chronic inflammatory bowel condition that affects more than 115,000 people in the UK. This article focuses on Crohn's disease in adolescents. Management of the condition in this group should address adolescent-specific characteristics and treatment goals. Key elements include optimising growth, pubertal development and social functioning, including education. The condition can affect an individual's mental and emotional wellbeing significantly, as well as their physical health. As adolescence is a time of great change, the additional burden of a chronic illness can prove difficult to manage. The authors provide information on the presentation of Crohn's disease in adolescence and insights into the particular issues encountered by this group.

2011-01-01

Climate change will influence the water cycle substantially, and extreme precipitation will become more frequent in many regions in the years to come. How should this fact be incorporated into design of urban drainage systems, if at all? And how important is climate change compared to other changes over time? Based on an analysis of the underlying key drivers of changes that are expected to affect urban drainage systems the current problems and their predicted development over time are presented. One key issue is management of risk and uncertainties and therefore a framework for design and analysis of urban structures in light of present and future uncertainties is presented.

With the emergence of global health comes governance challenges which are equally global in nature. This article identifies some of the initial limitations in analyses of global health governance (GHG) before discussing the focus of this special supplement: the framing of global health issues and the manner in which this impacts upon GHG. Whilst not denying the importance of material factors (such as resources and institutional competencies), the article identifies how issues can be framed in different ways, thereby creating particular pathways of response which in turn affect the potential for and nature of GHG. It also identifies and discusses the key frames operating in global health: evidence-based medicine, human rights, security, economics and development.

Managing water resources infrastructure in the face of different values

NASA Astrophysics Data System (ADS)

Mostert, Erik

Water resources infrastructure (WRI) plays a key role in water management. It can serve or negatively affect some seven to ten different and sometimes conflicting values. WRI management is therefore not a purely technical issue. Economic analyses can help to some extent, but only for values related to current human use. Multi-criteria analysis can cover all values, but in the end WRI management is not an analytical issue, but a governance issue. Different governance paradigms exist: markets, hierarchies and “third alternatives”, such as common pool resources management and network management. This article presents social learning as the most promising paradigm. Positive experiences with social learning have been described and guidance on putting social learning into practice exists. Nonetheless, there are no magic solutions for managing WRI in the face of different values.

Gopinathan, Unni; Lewin, Simon; Glenton, Claire

2014-12-01

To identify factors affecting the implementation of large-scale programmes to optimise the health workforce in low- and middle-income countries. We conducted a multicountry case study synthesis. Eligible programmes were identified through consultation with experts and using Internet searches. Programmes were selected purposively to match the inclusion criteria. Programme documents were gathered via Google Scholar and PubMed and from key informants. The SURE Framework - a comprehensive list of factors that may influence the implementation of health system interventions - was used to organise the data. Thematic analysis was used to identify the key issues that emerged from the case studies. Programmes from Brazil, Ethiopia, India, Iran, Malawi, Venezuela and Zimbabwe were selected. Key system-level factors affecting the implementation of the programmes were related to health worker training and continuing education, management and programme support structures, the organisation and delivery of services, community participation, and the sociopolitical environment. Existing weaknesses in health systems may undermine the implementation of large-scale programmes to optimise the health workforce. Changes in the roles and responsibilities of cadres may also, in turn, impact the health system throughout. © 2014 John Wiley & Sons Ltd.

Bioremediation of waste under ocean acidification: Reviewing the role of Mytilus edulis.

PubMed

Broszeit, Stefanie; Hattam, Caroline; Beaumont, Nicola

2016-02-15

Waste bioremediation is a key regulating ecosystem service, removing wastes from ecosystems through storage, burial and recycling. The bivalve Mytilus edulis is an important contributor to this service, and is used in managing eutrophic waters. Studies show that they are affected by changes in pH due to ocean acidification, reducing their growth. This is forecasted to lead to reductions in M. edulis biomass of up to 50% by 2100. Growth reduction will negatively affect the filtering capacity of each individual, potentially leading to a decrease in bioremediation of waste. This paper critically reviews the current state of knowledge of bioremediation of waste carried out by M. edulis, and the current knowledge of the resultant effect of ocean acidification on this key service. We show that the effects of ocean acidification on waste bioremediation could be a major issue and pave the way for empirical studies of the topic. Copyright © 2016 Elsevier Ltd.

Evaluation of psychology practitioner competence in clinical supervision.

Gonsalvez, Craig J; Crowe, Trevor P

2014-01-01

There is a growing consensus favouring the development, advancement, and implementation of a competency-based approach for psychology training and supervision. There is wide recognition that skills, attitude-values, and relationship competencies are as critical to a psychologist's competence as are knowledge capabilities, and that these key competencies are best measured during placements, leaving the clinical supervisor in an unparalleled position of advantage to provide formative and summative evaluations on the supervisee's progression towards competence. Paradoxically, a compelling body of literature from across disciplines indicates that supervisor ratings of broad domains of competence are systematically compromised by biases, including leniency error and halo effect. The current paper highlights key issues affecting summative competency evaluations by supervisors: what competencies should be evaluated, who should conduct the evaluation, how (tools) and when evaluations should be conducted, and process variables that affect evaluation. The article concludes by providing research recommendations to underpin and promote future progress and by offering practice recommendations to facilitate a more credible and meaningful evaluation of competence and competencies.

Towards guidelines for post-disaster vulnerability reduction in informal settlements.

Doberstein, Brent; Stager, Heather

2013-01-01

Although the development community has long recognised that securing land tenure and improving housing design can benefit significantly informal settlement residents, there is little research on these issues in communities exposed to natural disasters and hazards. Informal settlements often are located on land left vacant because of inherent risks, such as floodplains, and there is a long history worldwide of disasters affecting informal settlements. This research tackles the following questions: how can informal settlement vulnerabilities be reduced in a post-disaster setting?; and what are the key issues to address in post-disaster reconstruction? The main purpose of the paper is to develop a set of initial guidelines for post-disaster risk reduction in informal settlements, stressing connections to tenure and housing/community design in the reconstruction process. The paper examines disaster and reconstruction responses in two disaster-affected regions-Jimani, Dominican Republic, and Vargas State, Venezuela-where informal settlements have been hit particularly hard. © 2013 The Author(s).

The aim of this study was to learn from a wide range of hospital staff members about how the design of the patient room in which they work adversely affects their ergonomics or hinders their job performance. In addition to providing a healing space for patients, hospital patient rooms need to serve as functional workplaces for the people who provide clinical care, to clean, or to maintain room functions. Therefore, from a design perspective, it is important to understand the needs of all the users of hospital patient rooms with regard to room design. One hundred forty-seven people, representing 23 different occupational stakeholder groups, participated in either focus groups or interviews in which they were asked to identify room design issues that affect the performance of their work tasks. Key issues shared across multiple stakeholder groups included an inability to have eye contact with the patient when entering the room, inadequate space around the bed for the equipment used by stakeholders, the physical demands experienced as stakeholders move furnishings to accomplish their activities or access equipment, and a lack of available horizontal surfaces. Unique issues were also identified for a number of stakeholder groups. There are a number of issues that should be addressed in the next generation of hospital patient rooms, or when refurbishing existing facilities, so that all occupational stakeholder groups can work effectively, efficiently, and without undue physical stress. © The Author(s) 2015.

As health care is shifting from hospital to community, community health nurses (CHNs) are directly affected. This descriptive qualitative study sought to understand priority issues currently facing CHNs, explore development of a national vision for community health nursing, and develop recommendations to shape the future of the profession moving toward the year 2020. Focus groups and key informant interviews were conducted across Canada. Five key themes were identified: community health nursing in crisis now, a flawed health care system, responding to the public, vision for the future, and CHNs as solution makers. Key recommendations include developing a common definition and vision of community health nursing, collaborating on an aggressive plan to shift to a primary health care system, developing a comprehensive social marketing strategy, refocusing basic baccalaureate education, enhancing the capacity of community health researchers and knowledge in community health nursing, and establishing a community health nursing center of excellence.

2018-01-01

Microelement contents and metabolism are vitally important for cereal plant growth and development as well as end-use properties. While minerals phytotoxicity harms plants, microelement deficiency also affects human health. Genetic engineering provides a promising way to solve these problems. As plants vary in abilities to uptake, transport, and accumulate minerals, and the key enzymes acting on that process is primarily presented in this review. Subsequently, microelement function and biosafety assessment of transgenic cereal plants have become a key issue to be addressed. Progress in genetic engineering of cereal plants has been made with the introduction of quality, high-yield, and resistant genes since the first transgenic rice, corn, and wheat were born in 1988, 1990, and 1992, respectively. As the biosafety issue of transgenic cereal plants has now risen to be a top concern, many studies on transgenic biosafety have been carried out. Transgenic cereal biosafety issues mainly include two subjects, environmental friendliness and end-use safety. Different levels of gene confirmation, genomics, proteomics, metabolomics and nutritiomics, absorption, metabolism, and function have been investigated. Also, the different levels of microelement contents have been measured in transgenic plants. Based on the motivation of the requested biosafety, systematic designs, and analysis of transgenic cereal are also presented in this review paper. PMID:29599791

A variety of economic and programmatic issues are discussed concerning the development and deployment of a fleet of space-based solar power satellites (SSPS). The costs, uncertainties and risks associated with the current photovoltaic SSPS configuration, and with issues affecting the development of an economically viable SSPS development program are analyzed. The desirability of a low earth orbit (LEO) demonstration satellite and a geosynchronous (GEO) pilot satellite is examined and critical technology areas are identified. In addition, a preliminary examination of utility interface issues is reported. The main focus of the effort reported is the development of SSPS unit production, and operation and maintenance cost models suitable for incorporation into a risk assessment (Monte Carlo) model (RAM). It is shown that the key technology area deals with the productivity of man in space, not, as might be expected, with some hardware component technology.

A bottom up approach for engineering catchments through sustainable runoff management

NASA Astrophysics Data System (ADS)

Wilkinson, M.; Quinn, P. F.; Jonczyk, J.; Burke, S.

2010-12-01

There is no doubt that our catchments are under great stress. There have been many accounts around the world of severe flood events and water quality issues within channels. As a result of these, ecological habitats in rivers are also under pressure. Within the United Kingdom, all these issues have been identified as key target areas for policy. Traditionally this has been managed by a policy driven top down approach which is usually ineffective. A one ‘size fits all’ attitude often does not work. This paper presents a case study in northern England whereby a bottom up approach is applied to multipurpose managing of catchments at the source (in the order of 1-10km2). This includes simultaneous tackling of water quality, flooding and ecological issues by creating sustainable runoff management solutions such as storage ponds, wetlands, beaver dams and willow riparian features. In order to identify the prevailing issues in a specific catchment, full and transparent stakeholder engagement is essential, with everybody who has a vested interest in the catchment being involved from the beginning. These problems can then be dealt with through the use of a novel catchment management toolkit, which is transferable to similar scale catchments. However, evidence collected on the ground also allows for upscaling of the toolkit. The process gathers the scientific evidence about the effectiveness of existing or new measures, which can really change the catchment functions. Still, we need to get better at communicating the science to policy makers and policy therefore must facilitate a bottom up approach to land and water management. We show a test site for this approach in the Belford burn catchment (6km2), northern England. This catchment has problems with flooding and water quality. Increased sediment loads are affecting the nearby estuary which is an important ecological zone and numerous floods have affected the local village. A catchment engineering toolkit has been developed that puts in place novel measures to tackle diffuse pollution and reduce flood risk whilst collecting the science needed to influence the policy about these measures. This has been possible through four key practices: full stakeholder engagement, a problem solving agenda set in place, a bottom up approach to solving problems, and the collection of the appropriate science to support the benefits. Hands on, multi-objective work is the most cost effective way to manage catchments. Tackling water quality issues and controlling fast pathway runoff at the source in partnership with farmers and local landowners has proved to be the key to success. Tackling issues in sub-catchments can lead to solving problems at the catchment scale.

Key populations and human rights in the context of HIV services rendition in Ghana.

PubMed

Laar, Amos; DeBruin, Debra

2017-08-02

In line with its half century old penal code, Ghana currently criminalizes and penalizes behaviors of some key populations - populations deemed to be at higher risk of acquiring or transmitting Human Immunodeficiency Virus (HIV). Men who have sex with men (MSM), and sex workers (SWs) fit into this categorization. This paper provides an analysis of how enactment and implementation of rights-limiting laws not only limit rights, but also amplify risk and vulnerability to HIV in key and general populations. The paper derives from a project that assessed the ethics sensitivity of key documents guiding Ghana's response to its HIV epidemic. Assessment was guided by leading frameworks from public health ethics, and relevant articles from the international bill of rights. Ghana's response to her HIV epidemic does not adequately address the rights and needs of key populations. Even though the national response has achieved some public health successes, palpable efforts to address rights issues remain nascent. Ghana's guiding documents for HIV response include no advocacy for decriminalization, depenalization or harm reduction approaches for these key populations. The impact of rights-restricting codes on the nation's HIV epidemic is real: criminalization impedes key populations' access to HIV prevention and treatment services. Given that they are bridging populations, whatever affects the Ghanaian key populations directly, affects the general population indirectly. The right to the highest attainable standard of health, without qualification, is generally acknowledged as a fundamental human right. Unfortunately, this right currently eludes the Ghanaian SW and MSM. The paper endorses decriminalization as a means of promoting this right. In the face of opposition to decriminalization, the paper proposes specific harm reduction strategies as approaches to promote health and uplift the diminished rights of key populations. Thus the authors call on Ghana to remove impediments to public health services provision to these populations. Doing so will require political will and sufficient planning toward prioritizing HIV prevention, care and treatment programming for key populations.

A framework for multidimensional assessment of patient room configurations is presented. Twenty-three issues are considered and categorized under six domains of assessment: (1) patient safety, (2) staff efficiency, (3) circulation, (4) infection control, (5) patient considerations, and (6) family amenities. Use of the framework to rank issues by importance and assess six alternative patient room configurations by a diverse group of experts in a symposium is described. One of the key questions posed during inpatient room design is the location of the bathroom. What issues are affected by the variations in room configuration that arise from bathroom location? A complete articulation of the issues that potentially are affected by room configuration is not available in the literature. The list of issues was developed by the authors in preparation for a symposium. The symposium was organized in May 2007 and attended by 14 experts from four institutions. Six alternative room configurations were used. Variations in the configurations included: (1) three same-handed and three mirror-image rooms; (2) three outboard, two inboard, and one nested bathroom; and (3) three rooms with footwall bathrooms and three with headwall bathrooms. In a four-step process, the attendees ranked the issues, discussed them in detail, rated each room configuration against each issue on a seven-point suitability scale, and conducted an overall assessment of the six configurations. Based on the ratings and rankings provided by the symposium participants, outboard bathroom locations were found to be most suitable, followed by nested and inboard configurations. Furthermore, configurations with patient bathrooms located on the footwall were rated as more suitable than headwall locations. The authors recommend, however, that the framework be used to determine a suitable room configuration in a specific context, rather than to identify configurations that will perform well universally.

Thus an effort was made to bring together experts in both advanced human support technologies and microgravity fluids, transport and reaction processes. Expertise was drawn from academia, national laboratories, and the federal government. The intent was to bring about a thorough exchange of ideas and develop recommendations to address the significant open design and operation issues for human support systems that are affected by fluid physics, transport and reaction processes. This report provides a summary of key discussions, findings, and recommendations.

Extrinsic and intrinsic motivation at 30: Unresolved scientific issues.

PubMed

Reiss, Steven

2005-01-01

The undermining effect of extrinsic reward on intrinsic motivation remains unproven. The key unresolved issues are construct invalidity (all four definitions are unproved and two are illogical); measurement unreliability (the free-choice measure requires unreliable, subjective judgments to infer intrinsic motivation); inadequate experimental controls (negative affect and novelty, not cognitive evaluation, may explain "undermining" effects); and biased metareviews (studies with possible floor effects excluded, but those with possible ceiling effects included). Perhaps the greatest error with the undermining theory, however, is that it does not adequately recognize the multifaceted nature of intrinsic motivation (Reiss, 2004a). Advice to limit the use of applied behavior analysis based on "hidden" undermining effects is ideologically inspired and is unsupported by credible scientific evidence.

Clinical trials are investigating the potential benefit resulting from a reduced maximum storage interval for red blood cells (RBCs). The key drivers that determine RBC age at the time of issue vary among individual hospitals. Although progressive reduction in the maximum storage period of RBCs would be expected to result in smaller hospital inventories and reduced blood availability, the magnitude of the effect is unknown. Data on current hospital blood inventories were collected from 11 hospitals and three blood centers in five nations. A general predictive model for the age of RBCs at the time of issue was developed based on considerations of demand for RBCs in the hospital. Age of RBCs at issue is sensitive to the following factors: ABO group, storage age at the time of receipt by the hospital, the restock interval, inventory reserve, mean demand, and variation in demand. A simple model, based on hospital demand, may serve as the basis for examining factors affecting the storage age of RBCs in hospital inventories. The model suggests that the age of RBCs at the time of their issue to the patient depends on factors external to the hospital transfusion service. Any substantial change in the expiration date of stored RBCs will need to address the broad variation in demand for RBCs while attempting to balance considerations of availability and blood wastage. © 2013 American Association of Blood Banks.

Patient involvement in scoping the guideline is emphasized, but published initiatives actively involving patients are generally limited to the writing and reviewing phase. To assess patients' added value to the scoping phase of a multidisciplinary guideline on infertility. Qualitative interview study. We conducted interviews among 12 infertile couples and 17 professionals. We listed and compared the couples' and professionals' key clinical issues (=care aspects that need improvement) to be addressed in the guideline according to four domains: current guidelines, professionals, patients and organization of care. Main key clinical issues suggested by more than three quarters of the infertile couples and/or at least two professionals were identified and compared. Overall, we identified 32 key clinical issues among infertile couples and 23 among professionals. Of the defined main key clinical issues, infertile couples mentioned eight issues that were not mentioned by the professionals. These main key clinical issues mainly concerned patient-centred (e.g. poor information provision and poor alignment of care) aspects of care on the professional and organizational domain. Both groups mentioned two main key clinical issues collectively that were interpreted differently: the lack of emotional support and respect for patients' values. Including patients from the first phase of the guideline development process leads to valuable additional main key clinical issues for the next step of a multidisciplinary guideline development process and broadens the scope of the guideline, particularly regarding patient-centredness and organizational issues from a patients' perspective. © The Author 2016.

Strengthening good governance and preventing corruption in health care are universal challenges. The Karnataka Lokayukta (KLA), a public complaints agency in Karnataka state (India), was created in 1986 but played a prominent role controlling systemic corruption only after a change of leadership in 2001 with a new Lokayukta (ombudsman) and Vigilance Director for Health (VDH). This case study of the KLA (2001-06) analysed the:Scope and level of poor governance in the health sector; KLA objectives and its strategy; Factors which affected public health sector governance and the operation of the KLA. We used a participatory and opportunistic evaluation design, examined documents about KLA activities, conducted three site visits, two key informant and 44 semi-structured interviews and used a force field model to analyse the governance findings. The Lokayukta and his VDH were both proactive and economically independent with an extended social network, technical expertise in both jurisdiction and health care, and were widely perceived to be acting for the common good. They mobilized media and the public about governance issues which were affected by factors at the individual, organizational and societal levels. Their investigations revealed systemic corruption within the public health sector at all levels as well as in public/private collaborations and the political and justice systems. However, wider contextual issues limited their effectiveness in intervening. The departure of the Lokayukta, upon completing his term, was due to a lack of continued political support for controlling corruption. Governance in the health sector is affected by positive and negative forces. A key positive factor was the combined social, cultural and symbolic capital of the two leaders which empowered them to challenge corrupt behaviour and promote good governance. Although change was possible, it was precarious and requires continuous political support to be sustained.

Protecting indigenous rights. Guatemala.

PubMed

1996-01-01

Guatemala's recent ratification of the International Labor Organization (ILO) Convention regarding indigenous and tribal peoples (1989, No. 169) represents a commitment to guarantee the rights of the country's majority Mayan population. Ratifying governments are obligated to respect the traditional values and land rights of tribal and indigenous peoples and to consult with them on any decisions affecting their economic or social development. Ratification of this Convention was a key element in an eight-part UN-sponsored negotiation aimed at ending the civil war in Guatemala. Efforts are underway to promote dialogue between organized civil society and government. Negotiations in May 1996, conducted with ILO assistance, resulted in a socioeconomic agreement under which Guatemala will increase social investment in education, undertake agrarian reform, and institute tripartite consultation on all major social and economic issues. However, two key issues in the peace negotiations--the role of the army in civil society and constitutional reform--remain unresolved. The final global peace accord is expected to be signed in September 1996. UN organizations are already working to mobilize international support for transforming these agreements into political and social realities for the Guatemalan people.

Activity of NGO's supporting living donor kidney donations can affect the shortage of kidneys. Matnat Chaim is a Jewish orthodox organization active in Israel since 2009. This is a voluntary organization with aims to shorten and eliminate the waiting list for kidneys. Since the beginning of its activity, it has said to play a key role in 379 kidney transplantations. In 2015, out of 174 live donor kidney transplantations that took place in Israel, Matnat Chaim had a key role in 88 of them (50.6%). We found some ethical issues concerning the organization's activity. The donor can restrict his or her donation to specific characteristics of recipient which can result in organs transplanted in a homogeneous group of the population. Another issue is the question of whether nudging people to kidney donation takes place and whether it is valid to do so. We found that Matnat Chaim does a great deal for promotion and intermediation of kidney donations in Israel. This form of promotion can be implemented by other organizations and countries.

This study aimed to enhance the in-depth understanding of the contextual dimensions that shape the relationships between climate change communication approach and youth well-being. The study focused on university students who constitute the key stakeholders and future decision-makers and leaders for managing the long-term climate risks. A total of 10 focus group interviews were conducted with 117 undergraduate and graduate South African university students from over 12 universities located in different provinces of South Africa. In addition, another 16 interviews were also undertaken with university students, 10 interviews with key experts, and 3 youth national events were attended as participant-observation. As recipients of information on climate change, students' well-being was negatively affected by the media's pessimism of communicating risks and the inadequate or restricted networking of communicating solutions and strategies. As contributors to information on climate change, students faced key barriers to their efficacy and agency that entailed socio-cultural inequalities (e.g. race and language) and a lack of formal forums for community recognition, policy consultation and collaboration. In addition, for some students (e.g. journalism students), the lack of sufficient knowledge and skills on climate change and sustainability issues limited their ability to effectively communicate these issues to their audience. Platforms for interactive and reflective discussions, access to innovative technologies and social media, and opportunities for multi-stakeholder partnerships are keys to the success of youth-targeted and youth-initiated communication on climate change.

Initiation of insulin for type 2 diabetes mellitus patients: what are the issues? A qualitative study.

Type 2 diabetes mellitus is a progressive condition in which the pancreatic beta-cell function deteriorates with increasing duration of the disease. When good glycaemic control is not achieved despite adherence to oral hypoglycaemic drugs, healthy diet and lifestyle, insulin should be initiated. However, this is often delayed due to various reasons. We aimed to determine the issues relating to insulin initiation for diabetic patients managed in primary care polyclinics in Singapore. Qualitative data was obtained during four focus group discussions, with participation from healthcare professionals (HCPs), including physicians and nurses, and type 2 diabetes mellitus patients. The data was transcribed into text, coded and grouped into themes. Launching the topic and doctor-patient communication on insulin therapy were key issues in insulin initiation. Patient barriers to insulin commencement included: refusal to acknowledge the need for insulin therapy; its perception as a social stigma, an inconvenient mode of treatment or punishment for failure; and fear of needles, side-effects and complications. The HCP's attitude and experience with insulin therapy were also possible barriers. Our findings highlight that insulin initiation is affected by the complex interaction between the patients and HCPs, and other system factors. Patients may harbour misconceptions about insulin due to the late introduction of insulin therapy by HCPs or the way the therapy is being communicated to them. The key issues to address are the disparity in perceptions of diabetic control between HCPs and patients, and education regarding the need for insulin therapy.

Early prediction of student goals and affect in narrative-centered learning environments

NASA Astrophysics Data System (ADS)

Lee, Sunyoung

Recent years have seen a growing recognition of the role of goal and affect recognition in intelligent tutoring systems. Goal recognition is the task of inferring users' goals from a sequence of observations of their actions. Because of the uncertainty inherent in every facet of human computer interaction, goal recognition is challenging, particularly in contexts in which users can perform many actions in any order, as is the case with intelligent tutoring systems. Affect recognition is the task of identifying the emotional state of a user from a variety of physical cues, which are produced in response to affective changes in the individual. Accurately recognizing student goals and affect states could contribute to more effective and motivating interactions in intelligent tutoring systems. By exploiting knowledge of student goals and affect states, intelligent tutoring systems can dynamically modify their behavior to better support individual students. To create effective interactions in intelligent tutoring systems, goal and affect recognition models should satisfy two key requirements. First, because incorrectly predicted goals and affect states could significantly diminish the effectiveness of interactive systems, goal and affect recognition models should provide accurate predictions of user goals and affect states. When observations of users' activities become available, recognizers should make accurate early" predictions. Second, goal and affect recognition models should be highly efficient so they can operate in real time. To address key issues, we present an inductive approach to recognizing student goals and affect states in intelligent tutoring systems by learning goals and affect recognition models. Our work focuses on goal and affect recognition in an important new class of intelligent tutoring systems, narrative-centered learning environments. We report the results of empirical studies of induced recognition models from observations of students' interactions in narrative-centered learning environments. Experimental results suggest that induced models can make accurate early predictions of student goals and affect states, and they are sufficiently efficient to meet the real-time performance requirements of interactive learning environments.

The ways in which humans affect and are affected by their environments have been studied from many different perspectives over the past decades. However, it was not until the 1970s that the discussion of the ethical relationship between humankind and the environment formalized as an academic discipline with the emergence of environmental ethics. A few decades later, environmental health emerged as a discipline focused on the assessment and regulation of environmental factors that affect living beings. Our goal here is to begin a discussion specifically about the impact of modern environmental change on biomedical and social understandings of brain and mental health, and to align this with ethical considerations. We refer to this focus as Environmental Neuroethics, offer a case study to illustrate key themes and issues, and conclude by offering a five-tier framework as a starting point of analysis.

Cardiac rehabilitation (CR) programs reduce morbidity and mortality in patients with ischemic heart disease but are vastly underutilized in the United States, including the Veterans Health Administration (VA) Healthcare System. Numerous barriers affecting utilization have been identified in other health care systems, but the specific factors affecting Veterans are unknown. We sought to identify barriers and facilitators associated with utilization of CR in VA facilities. We performed a qualitative study of 56 VA patients, providers, and CR program managers at 30 VA facilities across the United States. We conducted semistructured interviews with key informants to explore their attitudes and knowledge toward CR. Interviews were conducted until thematic saturation occurred. Analyses using grounded theory to identify key themes were conducted using the qualitative data analysis package ATLAS.ti. We identified 6 themes as barriers and 5 as facilitators. The most common barriers to participation in CR were patient transportation issues (68%), lack of patient willingness to participate (41%), and no access to a nearby VA hospital with a CR program (30%). The most common facilitators were involvement of a dedicated provider or "clinical champion" (50%), provider knowledge of or experience with CR (48%), and patient desire for additional medical support (32%). Our findings suggest that addressing access issues and educating and activating providers on CR may increase utilization of CR programs. Targeting these specific factors may improve utilization of CR programs.

Saving the superstar: a review of the social factors affecting tiger conservation in India.

Tiger conservation in India represents an excellent case study of the many challenges facing conservation programs internationally. It is well understood that tigers are sensitive to human disturbances and large areas of habitat need to be protected for their conservation. Such protected areas in India are managed by the governments using an exclusionary approach. However, this approach is known to create several issues with local communities, including historical, legal, livelihood and management issues; with a volume of literature suggesting the inclusion of local communities in management. Yet, other evidence suggests that inclusion of communities in tiger conservation may lead to anthropogenic disturbances that can jeopardize tigers. The gravity of the situation is reflected in the recent disappearance of tigers from two key protected areas in India, the Sariska and Panna Tiger Reserves. This review paper connects the key literature from conservation biology, environmental history, management sciences, policy and political sciences to underline the gridlock of tiger conservation: it needs exclusive protected areas that antagonize communities, and it depends on the support of the same communities for success. We examine the possibility of reconciliation between these disciplines, and assert that research on tiger conservation needs to allow for an increasingly interdisciplinary approach. We call for a more integrated approach to tiger conservation, to examine the values inherent in conservation and to shed more light on the social factors that affect tiger conservation schemes.

Background Malaria in pregnancy has important consequences for mother and baby. Coverage with the World Health Organization–recommended prevention strategy for pregnant women in sub-Saharan Africa of intermittent preventive treatment in pregnancy (IPTp) and insecticide-treated nets (ITNs) is low. We conducted a systematic review to explore factors affecting delivery, access, and use of IPTp and ITNs among healthcare providers and women. Methods and Results We searched the Malaria in Pregnancy Library and Global Health Database from 1 January 1990 to 23 April 2013, without language restriction. Data extraction was performed by two investigators independently, and data was appraised for quality and content. Data on barriers and facilitators, and the effect of interventions, were explored using content analysis and narrative synthesis. We conducted a meta-analysis of determinants of IPTp and ITN uptake using random effects models, and performed subgroup analysis to evaluate consistency across interventions and study populations, countries, and enrolment sites. We did not perform a meta-ethnography of qualitative data. Ninety-eight articles were included, of which 20 were intervention studies. Key barriers to the provision of IPTp and ITNs were unclear policy and guidance on IPTp; general healthcare system issues, such as stockouts and user fees; health facility issues stemming from poor organisation, leading to poor quality of care; poor healthcare provider performance, including confusion over the timing of each IPTp dose; and women's poor antenatal attendance, affecting IPTp uptake. Key determinants of IPTp coverage were education, knowledge about malaria/IPTp, socio-economic status, parity, and number and timing of antenatal clinic visits. Key determinants of ITN coverage were employment status, education, knowledge about malaria/ITNs, age, and marital status. Predictors showed regional variations. Conclusions Delivery of ITNs through antenatal clinics presents fewer problems than delivery of IPTp. Many obstacles to IPTp delivery are relatively simple barriers that could be resolved in the short term. Other barriers are more entrenched within the overall healthcare system or socio-economic/cultural contexts, and will require medium- to long-term strategies.

A study on the impact of the GLOBE program on students' attitudes regarding environmental issues

NASA Astrophysics Data System (ADS)

Manfready, Gary Martin

A key objective in environmental curricula should be to instill responsible and concerned attitudes toward environmental issues. This can be accomplished through the application of innovative programs which emphasize the development of the affective domain of learning. The development of personal attitudes is one form of evidence that the affective domain is being addressed. This study was undertaken to determine the impact of the GLOBE program (Global Learning and Observation to Benefit the Environment) on the attitudes of students toward environmental issues. Three hundred and five middle and high school level students from four states were surveyed to determine their attitudes toward selected environmental statements. Results demonstrated that attitudes toward environmental issues of GLOBE students were significantly greater than non-GLOBE students. Additional analysis demonstrated that regardless of grade levels, gender, racial and ethnicity backgrounds, depth of GLOBE involvement, and degree of teachers' GLOBE experiences, GLOBE students display similar levels of attitudes toward environmental issues. Establishment of a reliable Likert scale measurement instrument was accomplished. Permission to use an existing survey was obtained. Additional items were added to increase validity. Establishment of reliability was accomplished through a Guttman split half analysis of the piloted instrument. Through the use of factor analysis, four categories or sub-groupings of attitudes were determined to exist. Reliability was established for the factors. These sub-groupings were identified as personal commitment to environmental protection, awareness of avenues for action, loci of control, and students' perception of teachers' abilities to present environmental topics. These categories were a part of the analysis of four hypotheses.

The effect of federal health policy on occupational medicine.

PubMed

McCunney, R J; Cikins, W

1990-01-01

All three branches of the federal government affect occupational medicine. Notable examples include: 1) the Department of Transportation ruling (1988) requiring drug testing in diverse areas of the transportation industry (executive branch); 2) the Workplace Drug Act (1988) calling for organizations to have a policy towards drug and alcohol abuse (legislative branch); and 3) the Supreme Court ruling on the constitutionality of drug testing in the transportation industry (1989) and that infectious diseases are a handicap in accordance with the 1973 Federal Rehabilitation Act (1987). The executive branch plays a major role in occupational medicine primarily through the Occupational Safety and Health Administration (OSHA), which issues standards based on a rule making process; the executive branch can also affect occupational medicine indirectly, as evidenced by President Reagan's Executive Order 12291 calling for Office of Management and Budget oversight of regulatory initiatives. The legislative branch enacts laws, conducts hearings, and requests reports on the operations of federal agencies. The judicial branch addresses occupational health issues when people affected by an executive ruling want to challenge the ruling; or in the case of the Supreme Court, when deliberating an issue over which two circuit courts of appeal have come to divergent opinions. The Occupational Medicine profession can participate in the political process through awareness of proposed legislation and by responding accordingly with letters, resolutions, or testimony. Similar options exist within the executive branch by participating in the rule-making process. A representative of the Governmental Affairs Committee, through periodic visits with key Washington representatives, can keep members of the American College of Occupational Medicine informed about federal legislative and regulatory activities. In appropriate cases, the organization can then take a formal position on governmental activities that affect the speciality.

The Impact of Positive and Negative Affect and Issue Framing on Issue Interpretation and Risk Taking.

PubMed

Mittal; Ross

1998-12-01

Two studies examined the influence of transient affective states and issue framing on issue interpretation and risk taking within the context of strategic decision making. In Study 1, participants in whom transient positive or negative affective states were induced by reading a short story showed systematic differences in issue interpretation and risk taking in a strategic decision making context. Compared to negative mood participants, those in a positive mood were more likely to interpret the strategic issue as an opportunity and displayed lower levels of risk taking. Study 2 replicated and extended these results by crossing affective states with threat and opportunity frames. Results showed that framing an issue (as a threat or an opportunity) had a stronger impact on issue interpretation among negative affect participants than among positive affect participants. Affective states also moderated the impact of issue framing on risk taking: the effect of framing on risk-taking was stronger under negative rather than positive affect. These results are interpreted via information-processing and motivational effects of affect on a decision maker. Copyright 1998 Academic Press.

Ethical Issues of Predictive Genetic Testing for Diabetes

PubMed Central

Haga, Susanne B.

2009-01-01

With the rising number of individuals affected with diabetes and the significant health care costs of treatment, the emphasis on prevention is key to controlling the health burden of this disease. Several genetic and genomic studies have identified genetic variants associated with increased risk to diabetes. As a result, commercial testing is available to predict an individual's genetic risk. Although the clinical benefits of testing have not yet been demonstrated, it is worth considering some of the ethical implications of testing for this common chronic disease. In this article, I discuss several issues that should be considered during the translation of predictive testing for diabetes, including familial implications, improvement of risk communication, implications for behavioral change and health outcomes, the Genetic Information Nondiscrimination Act, direct-to-consumer testing, and appropriate age of testing.

Does the Type of Higher Education Affect Labor Market Outcomes? Evidence from Egypt and Jordan.

2018-06-01

In Egypt and Jordan there is a substantial mismatch between the output of the higher education system and the needs of the labor market. Both demand and supply-side factors could be driving this mismatch. This paper tests a key supply-side issue, whether differences in the institutional structures and incentives in higher education affect the labor market outcomes of graduates. Specifically, we ask if the stronger alignment of incentives in private relative to public higher education institutions produces more employable human capital and better labor market outcomes. We examine the impact of the type of higher education institution a person attends on several labor market outcomes while controlling for his or her pre-enrollment characteristics. The results demonstrate that supply-side issues and institutional incentives have little impact on labor market outcomes while family background plays by far the largest role. Proposed reforms for higher education often suggest increasing the role of the private sector in provision of higher education. Our findings indicate that this approach is unlikely to improve labor market outcomes.

Global perspectives on nursing and its contribution to healthcare and health policy: thoughts on an emerging policy model.

PubMed

Shamian, Judith

2014-12-01

We know from rigorous evidence that nurses can exert an incredible impact on the everyday lives of people and their health. Nurses can also contribute in much wider spheres of influence by applying their knowledge and skills to address broader issues affecting population health across communities, nations and globally. Despite the prevalence of so many vexing health and social issues, nurses often fail to think globally, or even regionally, when they are lobbying for change. And while much political influence is local, some issues are simply too complex to rely on local influence alone. Importantly in all this, we must acknowledge the ways these complex health issues are shaped by economic and political agendas and not necessarily by healthcare agendas. As such, the nursing community has to act globally and locally, both within and outside of the nursing arena. This paper explores early thinking about an evolving model of spheres--or "bubbles"--of policy influence in which nurses can and must operate to more effectively impact key global health and healthcare challenges.

Communication in cancer care: psycho-social, interactional, and cultural issues. A general overview and the example of India.

2014-01-01

Communication is a core aspect of psycho-oncology care. This article examines key psychosocial, cultural, and technological factors that affect this communication. Drawing from advances in clinical work and accumulating bodies of empirical evidence, the authors identify determining factors for high quality, efficient, and sensitive communication and support for those affected by cancer. Cancer care in India is highlighted as a salient example. Cultural factors affecting cancer communication in India include beliefs about health and illness, societal values, integration of spiritual care, family roles, and expectations concerning disclosure of cancer information, and rituals around death and dying. The rapidly emerging area of e-health significantly impacts cancer communication and support globally. In view of current globalization, understanding these multidimensional psychosocial, and cultural factors that shape communication are essential for providing comprehensive, appropriate, and sensitive cancer care.

[Overcrowding in prisons and its impact on health].

PubMed

García-Guerrero, J; Marco, A

2012-02-01

Overcrowding in prisons is a common problem that affects many countries. It is difficult to define this term because there is no single internationally accepted standard. However, this is a situation that must be counteracted, because people's behaviour can be affected to the extent that it leads to self-harm or violent behaviour to others. But prison overcrowding also has other effects on the health and well being of the people living in these conditions and may also adversely affect public health and the prison system. It can increase the prevalence of diseases, particularly infectious and psychiatric disorders. It may also hinder the work of social rehabilitation and lead to inhuman, cruel or degrading treatment. This paper reviews the scant literature about overcrowding in prisons. Increasing awareness about the issue in the international community and prison administrations and above all, assigning specific economic resources, are key elements in preventing this deficit in social welfare and health care.

2011-01-01

Recently, the high-brightness LEDs have begun to be designed for illumination application. The increased electrical currents used to drive LEDs lead to thermal issues. Thermal management for LED module is a key design parameter as high operation temperature directly affects their maximum light output, quality, reliability and life time. In this review, only passive thermal solutions used on LED module will be studied. Moreover, new thermal interface materials and passive thermal solutions applied on electronic equipments are discussed which have high potential to enhance the thermal performance of LED Module.

Confirmatory Factor Analysis of a Questionnaire Measure of Managerial Stigma Towards Employee Depression.

PubMed

Martin, Angela J; Giallo, Rebecca

2016-12-01

Managers' attitudes play a key role in how organizations respond to employees with depression. We examine the measurement properties of a questionnaire designed to assess managerial stigma towards employees with depression. Using data from a sample of 469 Australian managers representing a wide range of industries and work settings, we conducted a confirmatory factor analysis to assess three proposed subscales representing affective, cognitive and behavioural forms of stigma. Results were equivocal indicating acceptable fit for two-factor (affective and cognitive + behavioural), three-factor (affective, cognitive and behavioural) and higher order models. Failure to demonstrate the discriminant validity of the cognitive and behavioural dimensions, even though they are theoretically distinct, suggests that further work on the scale is warranted. These results provide an extension to the psychometric profile of this measure (exploratory factor analysis; Martin, ). Development of strategies to operationalize this construct will benefit occupational health research and practice, particularly in interventions that aim to reduce the stigma of mental health issues in the workplace or where managers' attitudes are a key mechanism in intervention efficacy. We encourage future research on this measure pertaining in particular to further enhancing all aspects of its construct validity. Copyright © 2015 John Wiley & Sons, Ltd.

Background Immune thrombocytopenic purpura (ITP), a condition characterized by autoimmune-mediated platelet destruction and suboptimal platelet production, is associated with symptoms such as bruising, epistaxis, menorrhagia, mucosal bleeding from the gastrointestinal and urinary tracts and, rarely central nervous system bleeding. The aim of this research is to develop a conceptual model to describe the impact of ITP and its treatment on patients' health-related quality of life (HRQoL). Methods A literature search and focus groups with adult ITP patients were conducted to identify areas of HRQoL affected by ITP. Published literature was reviewed to identify key HRQoL issues and existing questionnaires used to assess HRQoL. Focus group transcripts were reviewed, and common themes were extracted by grouping conceptual categories that described the impact on HRQoL. Results The literature synthesis and themes from the focus group data suggest that decreased platelet counts, disease symptoms, and treatment side effects influence multiple domains of HRQoL for ITP patients. Key areas affected by ITP and its treatments include emotional and functional health, work life, social and leisure activities, and reproductive health. Conclusion ITP affects various areas of HRQoL. This conceptual model will help inform the evaluation of therapeutic strategies for ITP. PMID:18261217

Characterization of Factors Affecting Nanoparticle Tracking Analysis Results With Synthetic and Protein Nanoparticles.

Krueger, Aaron B; Carnell, Pauline; Carpenter, John F

2016-04-01

In many manufacturing and research areas, the ability to accurately monitor and characterize nanoparticles is becoming increasingly important. Nanoparticle tracking analysis is rapidly becoming a standard method for this characterization, yet several key factors in data acquisition and analysis may affect results. Nanoparticle tracking analysis is prone to user input and bias on account of a high number of parameters available, contains a limited analysis volume, and individual sample characteristics such as polydispersity or complex protein solutions may affect analysis results. This study systematically addressed these key issues. The integrated syringe pump was used to increase the sample volume analyzed. It was observed that measurements recorded under flow caused a reduction in total particle counts for both polystyrene and protein particles compared to those collected under static conditions. In addition, data for polydisperse samples tended to lose peak resolution at higher flow rates, masking distinct particle populations. Furthermore, in a bimodal particle population, a bias was seen toward the larger species within the sample. The impacts of filtration on an agitated intravenous immunoglobulin sample and operating parameters including "MINexps" and "blur" were investigated to optimize the method. Taken together, this study provides recommendations on instrument settings and sample preparations to properly characterize complex samples. Copyright © 2016. Published by Elsevier Inc.

Information superhighway: Issues affecting development

NASA Astrophysics Data System (ADS)

1994-09-01

Technological advances in the transmission of voice, video, and data are fostering fundamental changes in the telecommunications industry. For example, large local telephone companies plan to offer video services in competition with cable and broadcast television, while cable television companies plan to offer local telephone service over their wires in competition with the local telephone companies. The administration believes that these technological changes provide the opportunity to develop an 'Information Superhighway' that could provide every element of society with ready access to data, voice, and video communications. Concurrently, the Congress is considering sweeping changes to telecommunications regulations to keep pace with this dynamic industry. GAO prepared this report to serve as an overview of three key issues that decisionmakers may face as they deliberate telecommunications legislation; it focuses on three pivotal issues they face in formulating new telecommunications legislation: (1) managing the transition to a more competitive local telecommunications marketplace; (2) ensuring that all consumers have access to affordable telecommunications as competition develops; and (3) ensuring that the Information Superhighway provides adequate security, privacy, reliability, and interoperability.

The Evaluation and Office Management of Hemorrhoids for the Gastroenterologist.

PubMed

Guttenplan, Mitchel

2017-07-01

Hemorrhoid disease is extremely common, and seldom requires surgical intervention. The vast majority of patients can be cared for in the office setting and by the gastroenterologist. This piece aims to summarize the epidemiology and pathophysiology of hemorrhoid disease, along with the proper evaluation and office-based treatment of these patients. Most GI fellowship training programs spend little time on these topics, and the recommendation has been made to include anorectal care in the GI's "core curriculum." The use of the anoscope and a proper anorectal examination are keys to evaluating these patients, and the techniques available to treat these patients are described. Often overlooked in these patients are other anorectal issues that occur alongside hemorrhoidal issues very commonly-the most common being anal fissure. Comprehensive management of all of these issues will allow all but the most severely affected patients to avoid the expense and morbidity of surgical intervention. The anatomy, etiology, pathophysiology, diagnosis, and non-surgical treatment of hemorrhoid disease are presented with the gastroenterologist in mind.

eHealth Literacy and Health Behaviors Affecting Modern College Students: A Pilot Study of Issues Identified by the American College Health Association

Collins, William Bart; Wilson, Kari; Linnemeier, Georgiann; Englebert, Andrew Mark

2017-01-01

Background The eHealth Literacy Scale (eHEALS) has been widely adopted by researchers to understand how eHealth literacy can be put into context. eHealth researchers need to know how to promote positive health behavior changes across college students, given the importance of the Internet to acquire and use health information. The American College Health Association identified a set of key health issues that affect college students today. By understanding how eHEALS might be related to college students’ maintenance of their health and their use of online health resources, researchers will be provided with a better understanding of eHealth literacy and its pragmatic implications for health campaigns and future interventions. Objective The goal of the study was to examine what eHEALS reveals about college student health behaviors identified by the American College Health Association. To understand college student current health maintenance and their intentions to maintain their health and use online resources, the theory of planned behavior was used as the theoretical framework for the study. Methods Data were collected via a survey of 422 college students that included the eHEALS measure and questions about health issues based on the recommendations of the American College Health Association. These questions asked about college student current health, subsequent use of online health resources, and their intention to maintain their health and make use of such resources in the future. Results eHEALS was positively and significantly associated with all 8 areas of health issues identified by the American College Health Association for college student current maintenance of health and use of online health resources and for future intention of health maintenance and use of online resources. Key issues that emerged with eHealth literacy were maintaining safe sex practices and seeking out related information, seeking out information on an exercise regime, information on vaccinations, and maintaining a balanced diet. Conclusions These results suggest several areas that may be targeted for future health campaigns toward college students. In addition, eHEALS was found to be a useful instrument for college students in the United States. Lastly, these results point to a need to deliver targeted information to college students, particularly since eHEALS captures literacy based on positively phrased items. PMID:29258979

Experimental Study and Computational Simulations of Key Pebble Bed Thermo-mechanics Issues for Design and Safety

2014-07-08

An experimental and computational study, consisting of modeling and simulation (M&S), of key thermal-mechanical issues affecting the design and safety of pebble-bed (PB) reactors was conducted. The objective was to broaden understanding and experimentally validate thermal-mechanic phenomena of nuclear grade graphite, specifically, spheres in frictional contact as anticipated in the bed under reactor relevant pressures and temperatures. The contact generates graphite dust particulates that can subsequently be transported into the flowing gaseous coolent. Under postulated depressurization transients and with the potential for leaked fission products to be adsorbed onto graphite 'dust', there is the potential for fission products to escapemore » from the primary volume. This is a design safety concern. Furthermore, earlier safety assessment identified the distinct possibility for the dispersed dust to combust in contact with air if sufficient conditions are met. Both of these phenomena were noted as important to design review and containing uncertainty to warrant study. The team designed and conducted two separate effects tests to study and benchmark the potential dust-generation rate, as well as study the conditions under which a dust explosion may occure in a standardized, instrumented explosion chamber.« less

Potential adjustment methodology for missing data and reporting delay in the HIV Surveillance System, European Union/European Economic Area, 2015.

Accurate case-based surveillance data remain the key data source for estimating HIV burden and monitoring prevention efforts in Europe. We carried out a literature review and exploratory analysis of surveillance data regarding two crucial issues affecting European surveillance for HIV: missing data and reporting delay. Initial screening showed substantial variability of these data issues, both in time and across countries. In terms of missing data, the CD4+ cell count is the most problematic variable because of the high proportion of missing values. In 20 of 31 countries of the European Union/European Economic Area (EU/EEA), CD4+ counts are systematically missing for all or some years. One of the key challenges related to reporting delays is that countries undertake specific one-off actions in effort to capture previously unreported cases, and that these cases are subsequently reported with excessive delays. Slightly different underlying assumptions and effectively different models may be required for individual countries to adjust for missing data and reporting delays. However, using a similar methodology is recommended to foster harmonisation and to improve the accuracy and usability of HIV surveillance data at national and EU/EEA levels.

2010-01-01

This report identifies key human-performance-related issues associated with Next Generation Air Transportation System (NextGen) research in the NASA NextGen-Airspace Project. Four Research Focus Areas (RFAs) in the NextGen-Airspace Project - namely Separation Assurance (SA), Airspace Super Density Operations (ASDO), Traffic Flow Management (TFM), and Dynamic Airspace Configuration (DAC) - were examined closely. In the course of the research, it was determined that the identified human performance issues needed to be analyzed in the context of NextGen operations rather than through basic human factors research. The main gaps in human factors research in NextGen were found in the need for accurate identification of key human-systems related issues within the context of specific NextGen concepts and better design of the operational requirements for those concepts. By focusing on human-system related issues for individual concepts, key human performance issues for the four RFAs were identified and described in this report. In addition, mixed equipage airspace with components of two RFAs were characterized to illustrate potential human performance issues that arise from the integration of multiple concepts.

The web of silence: a qualitative case study of early intervention and support for healthcare workers with mental ill-health.

Moll, Sandra E

2014-02-08

There is a high rate of stress and mental illness among healthcare workers, yet many continue to work despite symptoms that affect their performance. Workers with mental health issues are typically ostracized and do not get the support that they need. If issues are not addressed, however, they could become worse and compromise the health and safety, not only of the worker, but his/her colleagues and patients. Early identification and support can improve work outcomes and facilitate recovery, but more information is needed about how to facilitate this process in the context of healthcare work. The purpose of this study was to explore the key individual and organizational forces that shape early intervention and support for healthcare workers who are struggling with mental health issues, and to identify barriers and opportunities for change. A qualitative, case study in a large, urban healthcare organization was conducted in order to explore the perceptions and experiences of employees across the organization. In-depth interviews were conducted with eight healthcare workers who had experienced mental health issues at work as well as eight workplace stakeholders who interacted with workers who were struggling (managers, coworkers, union leaders). An online survey was completed by an additional 67 employees. Analysis of the interviews and surveys was guided by a process of interpretive description to identify key barriers to early intervention and support. There were many reports of silence and inaction in response to employee mental health issues. Uncertainty in identifying mental health problems, stigma regarding mental ill health, a discourse of professional competence, social tensions, workload pressures, confidentiality expectations and lack of timely access to mental health supports were key forces in preventing employees from getting the help that they needed. Although there were a few exceptions, the overall study findings point to many barriers to supporting employees with mental health issues. In order to address the complex knowledge, attitudinal, interpersonal and organizational barriers to action, a multi-layered knowledge translation strategy is needed, that considers not only mental health literacy and anti-stigma interventions, but addresses the unique context of the work environment that can act as a barrier to change.

Lee, Keun Taik

2010-09-01

This article explores the effects of physically manipulated packaging materials on the quality and safety of meat products. Recently, innovative measures for improving quality and extending the shelf-life of packaged meat products have been developed, utilizing technologies including barrier film, active packaging, nanotechnology, microperforation, irradiation, plasma and far-infrared ray (FIR) treatments. Despite these developments, each technology has peculiar drawbacks which will need to be addressed by meat scientists in the future. To develop successful meat packaging systems, key product characteristics affecting stability, environmental conditions during storage until consumption, and consumers' packaging expectations must all be taken into consideration. Furthermore, the safety issues related to packaging materials must also be taken into account when processing, packaging and storing meat products.

Malaria is a serious, complex disease caused by parasites of the genus Plasmodium. Plasmodium parasites affect multiple tissues as they evade immune responses, replicate, sexually reproduce, and transmit between vertebrate and invertebrate hosts. The explosion of omics technologies has enabled large-scale collection of Plasmodium infection data, revealing systems-scale patterns, mechanisms of pathogenesis, and the ways that host and pathogen affect each other. Here, we provide an overview of recent efforts using systems biology approaches to study host-Plasmodium interactions and the biological themes that have emerged from these efforts. We discuss some of the challenges in using systems biology for this goal, key research efforts needed to address those issues, and promising future malaria applications of systems biology.

Welch, Brandon; Brinda, FNU

2017-01-01

Background Telemedicine is the use of technology to provide and support health care when distance separates the clinical service and the patient. Home-based telemedicine systems involve the use of such technology for medical support and care connecting the patient from the comfort of their homes with the clinician. In order for such a system to be used extensively, it is necessary to understand not only the issues faced by the patients in using them but also the clinician. Objectives The aim of this study was to conduct a heuristic evaluation of 4 telemedicine software platforms—Doxy.me, Polycom, Vidyo, and VSee—to assess possible problems and limitations that could affect the usability of the system from the clinician’s perspective. Methods It was found that 5 experts individually evaluated all four systems using Nielsen’s list of heuristics, classifying the issues based on a severity rating scale. Results A total of 46 unique problems were identified by the experts. The heuristics most frequently violated were visibility of system status and Error prevention amounting to 24% (11/46 issues) each. Esthetic and minimalist design was second contributing to 13% (6/46 issues) of the total errors. Conclusions Heuristic evaluation coupled with a severity rating scale was found to be an effective method for identifying problems with the systems. Prioritization of these problems based on the rating provides a good starting point for resolving the issues affecting these platforms. There is a need for better transparency and a more streamlined approach for how physicians use telemedicine systems. Visibility of the system status and speaking the users’ language are keys for achieving this. PMID:28438724

2017-07-01

Local governments attempting to respond to environmental change face an array of challenges. To better understand policy responses and factors influencing local government capacity to respond to environmental change, we studied three environmental issues affecting rural or peri-urban towns in different regions of New York State: climate change in the Adirondacks (n = 63 towns), loss of open space due to residential/commercial development in the Hudson Valley (n = 50), and natural gas development in the Southern Tier (n = 62). Our analysis focused on towns' progression through three key stages of the environmental policy process (issue awareness and salience, common goals and agenda setting, policy development and implementation) and the factors that affect this progression and overall capacity for environmental governance. We found that-when compared to towns addressing open space development and natural gas development-towns confronted with climate change were at a much earlier stage in the policy process and were generally less likely to display the essential resources, social support, and political legitimacy needed for an effective policy response. Social capital cultivated through collaboration and networking was strongly associated with towns' policy response across all regions and could help municipalities overcome omnipresent resource constraints. By comparing and contrasting municipal responses to each issue, this study highlights the processes and factors influencing local government capacity to address a range of environmental changes across diverse management contexts.

Mapping historical information for better understanding the causality factors of past disasters

Boudou, Martin; Lang, Michel; Vinet, Freddy; Coeur, Denis

2015-04-01

The Flood Directive of 2007 promotes the use of historical information in order to mitigate the impact of future extreme events. According to this text, the study of past events offers new insights for better understanding the causality factors of a disaster, from hydrometeorological keys to socio-political repercussions of the flood. In this presentation we decided to focus on the study of factors leading to the exceptionality of a hydrological flood event. This aspect is regularly pointed out by the feedbacks carried out after a catastrophic event and remains a subject of debate for risk managers. The role of antecedent meteorological conditions is especially underestimated by local authorities. These factors can however be considered as a key issue to appreciate the exceptional character of a hydrological disaster. For example the 2013 June floods in France that affected the region of Pyrenees revealed the significant contribution of snow melting to the discharges recorded. In an article of 2014, Schröter et al. showed that the soil moisture can be considered as a key driver of the generalised flood hazard intensity that affected Germany over the same month of June 2013. With regard to these assessments, some considerations emerge. Does a diachronic appraisal of past disasters point out the main issues responsible for an exceptional flood hazard level? Is there common causality issues involved into these extreme hydrological events? In order to answer these questions this presentation proposes a comparative analysis of nine major floods that impacted the French territory during the XXth century (from 1910 to 2010). The set is composed by different flood typologies (from torrential events to floods resulting from groundwater level rising) so as to get a complete view of flood risk in France. The methodology proposed relies on a cartographic approach to highlight the causality factors of these past hydrological disasters. For instance, mapping the rainfall data over the representation of the maximum discharges recorded can help to understand the significance of the rainfall event. In some cases, the use of textual historical information allows to emphasize the significance of other factors such as snow melting or the influence of anthropogenic infrastructures. Indeed, mapping historical information seems to be an original approach to represent the various spatial and temporal scales of historical disasters and an interesting tool to explore the exceptionality of the hazard level.

Space physiology IV: mathematical modeling of the cardiovascular system in space exploration.

PubMed

Keith Sharp, M; Batzel, Jerry Joseph; Montani, Jean-Pierre

2013-08-01

Mathematical modeling represents an important tool for analyzing cardiovascular function during spaceflight. This review describes how modeling of the cardiovascular system can contribute to space life science research and illustrates this process via modeling efforts to study postflight orthostatic intolerance (POI), a key issue for spaceflight. Examining this application also provides a context for considering broader applications of modeling techniques to the challenges of bioastronautics. POI, which affects a large fraction of astronauts in stand tests upon return to Earth, presents as dizziness, fainting and other symptoms, which can diminish crew performance and cause safety hazards. POI on the Moon or Mars could be more critical. In the field of bioastronautics, POI has been the dominant application of cardiovascular modeling for more than a decade, and a number of mechanisms for POI have been investigated. Modeling approaches include computational models with a range of incorporated factors and hemodynamic sophistication, and also physical models tested in parabolic and orbital flight. Mathematical methods such as parameter sensitivity analysis can help identify key system mechanisms. In the case of POI, this could lead to more effective countermeasures. Validation is a persistent issue in modeling efforts, and key considerations and needs for experimental data to synergistically improve understanding of cardiovascular responses are outlined. Future directions in cardiovascular modeling include subject-specific assessment of system status, as well as research on integrated physiological responses, leading, for instance, to assessment of subject-specific susceptibility to POI or effects of cardiovascular alterations on muscular, vision and cognitive function.

Engaging Underrepresented Group Youth in Environmental Science Research Activities: Catalyst for Change

The UC Berkeley East Bay Academy for Young Scientists (EBAYS) program provides youth from non-dominant communities in the East San Francisco Bay Area with unique opportunities to develop deeper understanding of environmental science content, as well as fundamental scientific practice skills. A key component of EBAYS programming is collaborative research projects that generate information useful in addressing critical environmental issues. This important component also provides opportunities for youth to present results of their investigations to other community members and to the scientific community at large. Inclusion of the environmental science research component is intended to help address the following program goals: A) increasing appreciation for the value of scientific practices as a tool for addressing important community-based issues; B) helping raise community awareness of important issues; C) sparking interest in other forms of community activism; D) increasing understanding of key science concepts; and E) generating valuable environmental quality data. In an effort to assess the degree to which EBAYS programming accomplishes these goals, as well as to evaluate its capacity to be effectively replicated on a broader scale, EBAYS staff has engaged in an investigation of associated learning and youth development outcomes. In this regard a research strategy has been developed that includes the use of assessment tools that will help foster a deeper understanding of the ways in which EBAYS programming increases the extent to which participants value the application of science, affects their overall occupational trajectory, and inspires them to consider careers in STEM.

Under an RBM paradigm, we claim that CSM has a key role to play in identifying the "risks to the most critical data elements and processes" that will drive targeted oversight. In order to support this claim, we first see how to characterize the risks that may affect clinical trials. We then discuss how CSM can be understood as a tool for providing a set of data-driven key risk indicators (KRIs), which help to organize adaptive targeted monitoring. Several case studies are provided where issues in a clinical trial have been identified thanks to targeted investigation after the identification of a risk using CSM. Using CSM to build data-driven KRIs helps to identify different kinds of issues in clinical trials. This ability is directly linked with the exhaustiveness of the CSM approach and its flexibility in the definition of the risks that are searched for when identifying the KRIs. In practice, a CSM assessment of the clinical database seems essential to ensure data quality. The atypical data patterns found in some centers and variables are seen as KRIs under a RBM approach. Targeted monitoring or data management queries can be used to confirm whether the KRIs point to an actual issue or not.

The Pawnee M5.8 event is the largest earthquake in Oklahoma since instrumented history. How this earthquake affects known seismogenic areas in the state is a key issue for seismic hazard probability studies. In this study, we quantify stress loading and unloading on seismicity-delineated faults from the Oklahoma Geological Survey relocated-earthquake catalog. Our modeling indicates that areas in Noble, Pawnee, and Payne county are more prone to triggered seismicity, while areas in Alfalfa, Grant, Garfield, Logan, Major, Oklahoma, and Woods county are less prone to seismic triggering.

Hardmask processes are a key technique to enable low-k semiconductors, but they can have an impact on patterning control, influencing defectivity, alignment, and overlay. Specifically, amorphous carbon layer (ACL) hardmask schemes can negatively affect overlay by creating distorted alignment signals. A new scheme needs to be developed that can be inserted where amorphous carbon is used but provide better alignment performance. Typical spin-on carbon (SOC) materials used in other hardmask schemes have issues with DCD-FCD skew. In this paper we will evaluate new spin-on carbon material with a higher carbon content that could be a candidate to replace amorphous carbon.

Juggling work and elder caregiving: work-life balance for aging American workers.

PubMed

Pitsenberger, D Jeanne

2006-04-01

As the American work force ages, the demands of caring for aging relatives increase. Family caregiving often interferes with workplace responsibilities, creating physical, emotional, and financial stress for caregivers. Employers must address the productivity losses created by absenteeism of workers who struggle with work-life issues created by caregiving roles. Occupational health nurses must understand the factors that affect workers in their caregiving roles and make appropriate nursing interventions. They are in key positions to help aging employees and their employers face the increased demands on work-life balance created by elder caregiving.

An interpretative phenomenological analysis of the psychological ramifications of hand-arm vibration syndrome.

PubMed

Ayers, Beverley; Forshaw, Mark

2010-05-01

With a substantial number of individuals diagnosed with Hand-Arm Vibration Syndrome (HAVS) and the preponderance of research focused on the medical and paramedical issues, the psychological and mental health sequelae of HAVS are largely neglected within the published literature. A series of focus groups and interviews were conducted involving nine people who had been diagnosed with HAVS. Transcripts of these interviews were analysed using Interpretative Phenomenological Analysis. Four key themes were identified within the discourse of individuals affected by HAVS: machismo; coping; psychological impacts; and the development of support services for HAVS. Clinical implications are briefly discussed.

Taking Legal Histories in Psychiatric Assessments.

PubMed

Morris, Nathaniel P

2018-05-25

People with mental illness are often disproportionately affected by the U.S. justice system, yet psychiatrists and other mental health professionals may avoid or feel uncomfortable talking with patients about legal history. This column examines why legal history is relevant to psychiatric assessments and provides guidance for talking with patients about these issues. Key aspects of taking a legal history are reviewed, including suggested questions, the role of collateral information, and considerations for medicolegal documentation. Developing skills in taking patients' legal histories may equip clinicians to better understand their patients' stories and to provide more effective psychiatric care.

Identifying the gaps in Nepalese migrant workers' health and well-being: a review of the literature.

2017-07-01

The health and well-being of migrant workers from low-income countries is often neglected in travel medicine. This article uses Nepal as a case study to highlight key issues affecting this particular group of international travellers. This narrative review used a comprehensive systematic literature search to identify relevant studies on Nepal. The included articles were thematically analysed leading to four key themes or risk factors. The search found 18 articles from which we identified 3 key themes related directly to migrant workers: (1) sexual risk taking; (2) occupational health and (3) lifestyles, and a fourth theme related to partners and family of migrant workers who are left behind in Nepal. Of the 18 included articles, 11 articles discussed sexual risk taking and HIV, whilst considerably fewer focused on work-related risk factors and lifestyle factors in migrant workers. Migrant workers who are generally healthy appear to be similar to tourist travellers in regarding sexual health as a key issue related to being abroad. Risky sexual behaviour increases in individuals separated from their usual sexual partners, away from their own communities and families, leading to the so-called 'situational disinhibition'. Considering the recent media coverage of deaths and injuries among migrant workers in the Middle East, it is interesting to see that their sexual health is more prevalent in the research literature. This article argues that travel medicine should provide more emphasis to the health and well-being of migrant workers as a highly vulnerable group of travellers with additional impact on the health of those left behind. © International Society of Travel Medicine, 2017.

Devolution and human resources in primary healthcare in rural Mali

PubMed Central

2011-01-01

Devolution, as other types of decentralization (e.g. deconcentration, delegation, privatization), profoundly changes governance relations in the health system. Devolution is meant to affect performance of the health system by transferring responsibilities and authority to locally elected governments. The key question of this article is: what does devolution mean for human resources for health in Mali? This article assesses the key advantages and dilemmas associated with devolution such as responsiveness to local needs, downward accountability and health worker retention. Challenges of politics and capacities are also addressed in relation to human resources for health at the local level. Examples are derived from experiences in Mali with a capacity development programme and from case studies of other countries. It is not research findings that are presented, but highlights of key issues at stake aimed at inspiring the debate in Mali and elsewhere. A first lesson from the discussion suggests that in the context of human resources for health, decentralization of authority and resources is not the main issue. The challenge is to develop or strengthen accountability of those who decide and act, whether they are local politicians, bureaucrats or community representatives. If decentralization policies do not address public accountability, they will not fundamentally change human resource management, quality and equity of staffing. A second lesson is that successful devolution requires innovations in capacity development of all actors involved and in designing effective incentive measures. A final key conclusion is that the topic of devolution policy and its effects on human resources for health, and vice versa, merit more attention. A better understanding may lead to more appropriate policy designs and better preparation for the actors involved in countries that are embarking on decentralization, as is the case in Mali.

Africa continues to bear a disproportionate share of the global HIV/AIDS, tuberculosis (TB) and malaria burden. The development and distribution of safe, effective and affordable vaccines is critical to reduce these epidemics. However, conducting HIV/AIDS, TB, and/or malaria vaccine trials simultaneously in developing countries, or in populations affected by all three diseases, is likely to result in numerous ethical challenges. In order to explore convergent ethical issues in HIV/AIDS, TB and malaria vaccine trials in Africa, the Ethics, Law and Human Rights Collaborating Centre of the WHO/UNAIDS African AIDS Vaccine Programme hosted a consultation on the Convergent Ethical Issues in HIV/AIDS, TB and Malaria Vaccine Trials in Africa in Durban, South Africa on the 10-11 February 2009. Key cross cutting ethical issues were prioritized during the consultation as community engagement; ancillary care obligations; care and treatment; informed consent; and resource sharing. The consultation revealed that while there have been few attempts to find convergence on ethical issues between HIV/AIDS, TB and malaria vaccine trial fields to date, there is much common ground and scope for convergence work between stakeholders in the three fields.

Europe's Shifting Response to HIV/AIDS: From Human Rights to Risk Management.

Smith, Julia

2016-12-01

Despite a history of championing HIV/AIDS as a human rights issue, and a rhetorical commitment to health as a human right, European states and institutions have shifted from a rights-based response to a risk management approach to HIV/AIDS since the economic recession of 2008. An interdisciplinary perspective is applied to analyze health policy changes at the national, regional, and global levels by drawing on data from key informant interviews, and institutional and civil society documents. It is demonstrated that, in the context of austerity measures, member states such as the UK and Greece reduced commitments to rights associated with HIV/AIDS; at the regional level, the EU failed to develop rights-based approaches to address the vulnerabilities and health care needs of key populations affected by HIV/AIDS, particularly migrants and sex workers; and at the global level, the EU backtracked on commitments to global health and is prioritizing the intellectual property rights of pharmaceutical companies over the human rights of people living with HIV/AIDS. The focus within and from the EU is on containment, efficiency, and cost reduction. The rights of those most affected are no longer prioritized.

Angry, Scared, and Unsure: Mental Health Consequences of Contaminated Water in Flint, Michigan.

PubMed

Cuthbertson, Courtney A; Newkirk, Cathy; Ilardo, Joan; Loveridge, Scott; Skidmore, Mark

2016-12-01

Natural and manmade crises impact community-level behavioral health, including mental health and substance use. This article shares findings from a larger project about community behavioral health, relevant to the ongoing water crisis in Flint, Michigan, using data from a larger study, involving monthly surveys of a panel of key informants from Genesee County. The data come from open-response questions and are analyzed as qualitative data using grounded theory techniques. Although respondents were not asked about the water issues in Flint, participants commented that the water situation was increasing stress, anxiety, and depression among the city's population. Participants thought these mental health issues would affect the entire community but would be worse among low-income, African American populations in the city. Mental health consequences were related not only to the water contamination but to distrust of public officials who are expected and have the authority to resolve the issues. The mental health effects of this public health crisis are significant and have received inadequate attention in the literature. Public health response to situations similar to the water issues in Flint should include sustained attention mental health.

Selective perceptions of hydraulic fracturing.

Sarge, Melanie A; VanDyke, Matthew S; King, Andy J; White, Shawna R

2015-01-01

Hydraulic fracturing (HF) is a focal topic in discussions about domestic energy production, yet the American public is largely unfamiliar and undecided about the practice. This study sheds light on how individuals may come to understand hydraulic fracturing as this unconventional production technology becomes more prominent in the United States. For the study, a thorough search of HF photographs was performed, and a systematic evaluation of 40 images using an online experimental design involving N = 250 participants was conducted. Key indicators of hydraulic fracturing support and beliefs were identified. Participants showed diversity in their support for the practice, with 47 percent expressing low support, 22 percent high support, and 31 percent undecided. Support for HF was positively associated with beliefs that hydraulic fracturing is primarily an economic issue and negatively associated with beliefs that it is an environmental issue. Level of support was also investigated as a perceptual filter that facilitates biased issue perceptions and affective evaluations of economic benefit and environmental cost frames presented in visual content of hydraulic fracturing. Results suggested an interactive relationship between visual framing and level of support, pointing to a substantial barrier to common understanding about the issue that strategic communicators should consider.

Taking the hit: focusing on caregiver "error" masks organizational-level risk factors for nursing aide assault.

Beliefs about the causes of events have implications for emotional reactions, distress, expectations for the future, and behavioral responses. In this article we report on two issues: the organizational context that contributes to nursing aide (NA) assault and reporting, and serendipitous findings that arose from investigating unexpected response rates to a survey. Data were collected in 11 rural nursing homes using a structured prospective event-reporting diary to collect detailed information about incidents of physical aggression, followed by focus groups to further explore NAs' perceptions of these events. Here we report on analysis of 19 focus groups conducted with 138 NAs. Participants described organizational-level factors that constrained their practice, affected their interactions with residents, and created a context that put them at risk for physical assault. These factors also affected their willingness to provide written documentation about aggressive incidents. The key issues were frustration at being blamed for causing aggression, lack of action to address the problem, and a desire for respect and involvement in decision making. Organizational changes are needed to modify the contextual factors contributing to assault risk. Researchers must be willing to modify study designs to more fully understand the nature of the problem studied.

Group decisions in humans and animals: a survey

Conradt, Larissa; List, Christian

2008-01-01

Humans routinely make many decisions collectively, whether they choose a restaurant with friends, elect political leaders or decide actions to tackle international problems, such as climate change, that affect the future of the whole planet. We might be less aware of it, but group decisions are just as important to social animals as they are for us. Animal groups have to collectively decide about communal movements, activities, nesting sites and enterprises, such as cooperative breeding or hunting, that crucially affect their survival and reproduction. While human group decisions have been studied for millennia, the study of animal group decisions is relatively young, but is now expanding rapidly. It emerges that group decisions in animals pose many similar questions to those in humans. The purpose of the present issue is to integrate and combine approaches in the social and natural sciences in an area in which theoretical challenges and research questions are often similar, and to introduce each discipline to the other's key ideas, findings and successful methods. In order to make such an introduction as effective as possible, here, we briefly review conceptual similarities and differences between the sciences, and provide a guide to the present issue.

Clinical trials are crucial to improve cancer treatment but recruitment is difficult. Optimised patient information has been recognised as a key issue. In line with the increasing focus on patients' perspectives in health care, we aimed to study patients' opinions about the written information used in three clinical trials for breast cancer. Primary data collection was done in focus group interviews with breast cancer patient advocates. Content analysis identified three major themes: comprehensibility, emotions and associations, and decision making. Based on the advocates' suggestions for improvements, 21 key issues were defined and validated through a questionnaire in an independent group of breast cancer patient advocates. Clear messages, emotionally neutral expressions, careful descriptions of side effects, clear comparisons between different treatment alternatives and information about the possibility to discontinue treatment were perceived as the most important issues. Patients' views of the information in clinical trials provide new insights and identify key issues to consider in optimising future written information and may improve recruitment to clinical cancer trials. © 2010 Blackwell Publishing Ltd.

Emerging ICT implementation issues in aged care.

Kapadia, Vasvi; Ariani, Arni; Li, Junhua; Ray, Pradeep K

2015-11-01

Demand for aged care services continues to soar as a result of an aging population. This increasing demand requires more residential aged care facilities and healthcare workforce. One recommended solution is to keep older people in their homes longer and support their independent life through the use of information and communication technologies (ICT). However, the aged care sector is still in the early stages of adopting ICT. The aim of this study was to identify the key issues that affect the adoption of ICT in the aged care sector. A systematic literature review was undertaken and involved four steps. The first two steps aimed to identify and select relevant articles. Data was then extracted from the selected articles and identified issues were analyzed and grouped into three major categories. ICT adoption issues were categorized into different perspectives, representing older people, health professionals and management. Our findings showed that all three groups were mostly concerned with issues around behavior, cost and lack of technical skills. Findings reported in this study will help decision makers at aged care settings to systematically understand issues related to ICT adoption and thus proactively introduce interventions to improve use of ICT in this sector. On the basis of our findings, we suggest future research focus on the examination of aged care workflow and assessment of return on ICT investment. Copyright © 2015.

A review of seven research studies pertaining to Single Pilot IFR (SPIFR) operations was performed. Two studies were based on questionnaire surveys; two based on National Transportation Safety Board (NTSB) reports; two were based on Aviation Safety Reporting System (ASRS) incident reports, and one report used event analysis and statistics to forecast problems. The results obtained in each study were extracted and integrated. Results were synthesized and key issues pertaining to SPIFR operations problems were identified. The research that was recommended by the studies and that addressed the key issues is catalogued for each key issue.

Information bias in health research: definition, pitfalls, and adjustment methods

Althubaiti, Alaa

2016-01-01

As with other fields, medical sciences are subject to different sources of bias. While understanding sources of bias is a key element for drawing valid conclusions, bias in health research continues to be a very sensitive issue that can affect the focus and outcome of investigations. Information bias, otherwise known as misclassification, is one of the most common sources of bias that affects the validity of health research. It originates from the approach that is utilized to obtain or confirm study measurements. This paper seeks to raise awareness of information bias in observational and experimental research study designs as well as to enrich discussions concerning bias problems. Specifying the types of bias can be essential to limit its effects and, the use of adjustment methods might serve to improve clinical evaluation and health care practice. PMID:27217764

In this article, we consider how to leverage some of the rapid advances in developmental neuroscience in ways that can improve adolescent health. We provide a brief overview of several key areas of scientific progress relevant to these issues. We then focus on two examples of important health problems that increase sharply during adolescence: sleep problems and affective disorders. These examples illustrate how an integrative, developmental science approach provides new insights into treatment and intervention. They also highlight a cornerstone principle: how a deeper understanding of potentially modifiable factors-at key developmental inflection points along the trajectory toward clinical disorders-is beginning to inform, and may eventually transform, a broad range of innovative early intervention strategies to improve adolescent health.

2011-06-01

Landscape classification is the basis of the researches on landscape structure, process, and function, and also, the prerequisite for landscape evaluation, planning, protection, and management, directly affecting the precision and practicability of landscape research. This paper reviewed the research progress on the landscape classification system, theory, and methodology, and summarized the key problems and deficiencies of current researches. Some major landscape classification systems, e. g. , LANMAP and MUFIC, were introduced and discussed. It was suggested that a qualitative and quantitative comprehensive classification based on the ideology of functional structure shape and on the integral consideration of landscape classification utility, landscape function, landscape structure, physiogeographical factors, and human disturbance intensity should be the major research directions in the future. The integration of mapping, 3S technology, quantitative mathematics modeling, computer artificial intelligence, and professional knowledge to enhance the precision of landscape classification would be the key issues and the development trend in the researches of landscape classification.

2007-06-01

Restoration and reconstruction of degraded riparian ecosystem caused by natural and anthropogenic disturbances is one of the important issues in restoration ecology and watershed ecology. The disturbances on riparian ecosystem include flow regime alteration, direct modification and watershed disturbance, which have different affecting mechanisms. Flow regime alteration affects riparian ecosystem by changing riparian soil humidity, oxidation-reduction potential, biotaliving environment, and sediment transfer; direct modification affects riparian vegetation diversity through human activities and exotic plants invasion; and watershed disturbance mainly manifests in the channel degradation, aggradation or widening, the lowering of groundwater table, and the modification in fluvial process. The assessment objects of riparian restoration are riparian ecosystem components, and the assessment indicators are shifted from ecological to synthetic indices. Riparian restoration should be based on the detailed understanding of the biological and physical processes which affect riparian ecosystem, and implemented by vegetation restoration and hydrological adjustment at watershed or landscape scale. To extend the research scales and objects and to apply interdisciplinary approaches should be the key points in the further studies on the degradation mechanisms and restoration of riparian ecosystem.

2011-01-01

Genetic testing in the workplace holds the promise of improving worker health but also raises ethical, legal, and social issues. In considering such testing, it is critical to understand the perspectives of workers, who are most directly affected by it, and occupational health professionals, who are often directly involved in its implementation. Therefore, a series of focus groups of unionized workers (n=25) and occupational medicine physicians (n=23) was conducted. The results demonstrated strikingly different perspectives of workers and physicians in several key areas, including the goals and appropriateness of genetic testing, and methods to minimize its risks. In general, workers were guided by a profound mistrust of the employer, physician, and government, while physicians were guided primarily by scientific and medical concerns, and, in many cases, by the business concerns distrusted by the workers.

Final case for a stainless steel diagnostic first wall on ITER

In 2010 the ITER Organization (IO) proposed to eliminate the beryllium armour on the plasma-facing surface of the diagnostic port plugs and instead to use bare stainless steel (SS), simplifying the design and providing significant cost reduction. Transport simulations at the IO confirmed that charge-exchange sputtering of the SS surfaces would not affect burning plasma operation through core impurity contamination, but a second key issue is the potential melt damage/material loss inflicted by the intense photon radiation flashes expected at the thermal quench of disruptions mitigated by massive gas injection. This paper addresses this second issue through a combination of ITER relevant experimental heat load tests and qualitative theoretical arguments of melt layer stability. It demonstrates that SS can be employed as material for the port plug plasma-facing surface and this has now been adopted into the ITER baseline.

Cutting to the chase: what physician executives need to know about HIPAA.

All health care providers, plans, and clearinghouses will be affected by the federally mandated uniform standards for administrative transactions. This article presents distilled core information about the Health Insurance Portability and Accountability Act (HIPAA) legislation--the standards, penalties for violations, and status of final rules. It also raises several key unsolved issues of which clinicians, executives, and health care providers must be aware so they can prepare and plan for the upcoming changes. HIPAA is intended to improve the efficiency and effectiveness of the health care system, as well as to increase the protection and confidentiality of individually identifiable health information. The costs of making the transition to the legislated standards and processes remain a worrisome factor. Although there are two years before these standards must be implemented, and cost and compliance issues resolved, work has already begun in many health institutions to identify and address them.

Accidental versus operational oil spills from shipping in the Baltic Sea: risk governance and management strategies.

PubMed

Hassler, Björn

2011-03-01

Marine governance of oil transportation is complex. Due to difficulties in effectively monitoring procedures on vessels en voyage, incentives to save costs by not following established regulations on issues such as cleaning of tanks, crew size, and safe navigation may be substantial. The issue of problem structure is placed in focus, that is, to what degree the specific characteristics and complexity of intentional versus accidental oil spill risks affect institutional responses. It is shown that whereas the risk of accidental oil spills primarily has been met by technical requirements on the vessels in combination with Port State control, attempts have been made to curb intentional pollution by for example increased surveillance and smart governance mechanisms such as the No-Special-Fee system. It is suggested that environmental safety could be improved by increased use of smart governance mechanisms tightly adapted to key actors' incentives to alter behavior in preferable directions.

A total of 685 videos uploaded onto YouTube between 2006 and 2014 were content analyzed. Results demonstrated that the top three key issues about ADHD were symptom, child, and treatment. Doctor, patient, and supporter were the three most interviewed sources. Videos from the public sector including the government, company representative, and public organizations were relatively rare compared to other sources suggesting the potential for a greater role for the government and public sector contributions to YouTube to provide credible information relevant to public awareness, campaigns, and policy announcements. Meanwhile, many personal videos in the episodic frame advocated social solutions. This result implies that YouTube videos about health information from the private sectors have the potential to affect change at the social level.

This study captured older people's attitudes and concerns about sex and sexuality in later life by synthesising qualitative research published on this issue. The systematic review was conducted between November 2015 and June 2016 based on a pre-determined protocol. Key words were used to ensure a precise search strategy. Empirically based, qualitative literature from 18 databases was found. Twenty studies met the inclusion criteria. Thomas and Harden's thematic synthesis was used to generate 'analytical themes' which summarise this body of literature. Three main themes were identified: (a) social legitimacy for sexuality in later life; (b) health, not age, is what truly impacts sexuality, and (c) the hegemony of penetrative sex. The themes illustrate the complex and delicate relation between ageing and sexuality. Older adults facing health issues that affect sexual function adopt broader definitions of sexuality and sexual activity.

International labor migration overseas is very complex and involves multiple dimensional issues, ranging from economic to social, political, and cultural issues. A very long history migration has affect the live of households which has been dependent very much on it, not only in economic terms but also in broader aspects.This research aim is to understand the history and process of international labor migration from the District of Ponorogo. The research was done using mixed method design, combining quantitative and qualitative approaches. Firstly, a survey was done by involving about a thousand households and followed with qualitative method applying in-depth interviews and FGDs to sub-samples households and some key informants. The results have shown that intergenerational migration has established in Ponogoro. There has been an expansion of destination countries with the establishment of many international migration routes. Migrant workers from Ponorogo have traveled to very distant continents and to more modern countries.

Challenging ocular image recognition

Ocular recognition is a new area of biometric investigation targeted at overcoming the limitations of iris recognition performance in the presence of non-ideal data. There are several advantages for increasing the area beyond the iris, yet there are also key issues that must be addressed such as size of the ocular region, factors affecting performance, and appropriate corpora to study these factors in isolation. In this paper, we explore and identify some of these issues with the goal of better defining parameters for ocular recognition. An empirical study is performed where iris recognition methods are contrasted with texture and point operators on existing iris and face datasets. The experimental results show a dramatic recognition performance gain when additional features are considered in the presence of poor quality iris data, offering strong evidence for extending interest beyond the iris. The experiments also highlight the need for the direct collection of additional ocular imagery.

Putting the value into biosimilar decision making: the judgment value criteria.

Uncertainties remain the key issue surrounding biosimilars, although decisions regarding their use must be made. The challenges for policymakers, doctors, patients and others seeking to navigate in the uncharted waters of biosimilars must be clarified. At the most basic level, scientific understanding of the issue remains limited and when making decisions, policymakers must consider all those affected by health policy decisions, particularly the ultimate recipients of these medicines: the patients. The biosimilar-value chain relies on measurement of comparabilities. The goal is to demonstrate how, from a molecular perspective, closely similar they are or are not and how potential small differences may be relevant to clinical outcomes. To critically understand these points, this conceptual paper will present a knowledge-value chain and discuss each dimension assigning value in the decision making process re-utilization of biosimilars.

2009-06-01

To describe the factors that affect the use of new combination vaccines, the authors conducted qualitative interviews with pediatricians (n = 7), state immunization program managers (n = 7), and health insurance plan representatives (n = 6 plans). Respondents from each group identified reduction in pain and potentially increased immunization coverage as key benefits of new combination vaccines. For several pediatricians, low reimbursement for cost of vaccine doses and potential loss of fees for vaccine administration were barriers to using combination vaccines. For most state immunization programs, the higher cost of combination vaccines relative to separate vaccines was an important consideration but not a barrier to adoption. Most insurers were not aware of the financial issues for providers, but some had changed or were willing to change reimbursement to support the use of new combination vaccines. Financial issues for pediatric practices that purchase and provide vaccines for children may be an important barrier to offering combination vaccines.

Transient performance analysis of the master cylinder hydraulic system of a 6.3 MN fineblanking press

Yi, Guodong; Li, Jin

2018-03-01

The master cylinder hydraulic system is the core component of the fineblanking press that seriously affects the machine performance. A key issue in the design of the master cylinder hydraulic system is dealing with the heavy shock loads in the fineblanking process. In this paper, an equivalent model of the master cylinder hydraulic system is established based on typical process parameters for practical fineblanking; then, the response characteristics of the master cylinder slider to the step changes in the load and control current are analyzed, and lastly, control strategies for the proportional valve are studied based on the impact of the control parameters on the kinetic stability of the slider. The results show that the kinetic stability of the slider is significantly affected by the step change of the control current, while it is slightly affected by the step change of the system load, which can be improved by adjusting the flow rate and opening time of the proportional valve.

In countries with high HIV prevalence and high fertility desires, the rights of HIV-affected couples to have children are a pressing issue. Conception among people living with HIV carries risks for both horizontal and vertical HIV transmission. In Uganda ~100,000 HIV-infected women become pregnant annually. Providers face a number of challenges to preventing HIV transmission, reducing unplanned pregnancies, and ensuring safer conception. We report findings from interviews with 27 HIV-affected couples (54 individuals) in Uganda. We explored key cultural and structural factors shaping couples' childbearing decisions. Our data reveal a complex intersection of gender norms, familial expectations, relationship dynamics, and HIV stigma influencing their decisions. Participants provided insights regarding provider bias, stigma, and the gendering of reproductive healthcare. To reduce horizontal transmission HIV and family planning clinics must address men's and women's concerns regarding childbearing with specific attention to cultural and structural challenges.

Cleaning by clustering: methodology for addressing data quality issues in biomedical metadata.

Hu, Wei; Zaveri, Amrapali; Qiu, Honglei; Dumontier, Michel

2017-09-18

The ability to efficiently search and filter datasets depends on access to high quality metadata. While most biomedical repositories require data submitters to provide a minimal set of metadata, some such as the Gene Expression Omnibus (GEO) allows users to specify additional metadata in the form of textual key-value pairs (e.g. sex: female). However, since there is no structured vocabulary to guide the submitter regarding the metadata terms to use, consequently, the 44,000,000+ key-value pairs in GEO suffer from numerous quality issues including redundancy, heterogeneity, inconsistency, and incompleteness. Such issues hinder the ability of scientists to hone in on datasets that meet their requirements and point to a need for accurate, structured and complete description of the data. In this study, we propose a clustering-based approach to address data quality issues in biomedical, specifically gene expression, metadata. First, we present three different kinds of similarity measures to compare metadata keys. Second, we design a scalable agglomerative clustering algorithm to cluster similar keys together. Our agglomerative cluster algorithm identified metadata keys that were similar, based on (i) name, (ii) core concept and (iii) value similarities, to each other and grouped them together. We evaluated our method using a manually created gold standard in which 359 keys were grouped into 27 clusters based on six types of characteristics: (i) age, (ii) cell line, (iii) disease, (iv) strain, (v) tissue and (vi) treatment. As a result, the algorithm generated 18 clusters containing 355 keys (four clusters with only one key were excluded). In the 18 clusters, there were keys that were identified correctly to be related to that cluster, but there were 13 keys which were not related to that cluster. We compared our approach with four other published methods. Our approach significantly outperformed them for most metadata keys and achieved the best average F-Score (0.63). Our algorithm identified keys that were similar to each other and grouped them together. Our intuition that underpins cleaning by clustering is that, dividing keys into different clusters resolves the scalability issues for data observation and cleaning, and keys in the same cluster with duplicates and errors can easily be found. Our algorithm can also be applied to other biomedical data types.

Listening for Prescriptions: A National Consultation on Pharmaceutical Policy Issues

Morgan, Steve; Cunningham, Colleen M.

2010-01-01

Objectives and Methods: Pharmaceutical policy is an increasingly costly, essential and challenging component of health system management. We sought to identify priority pharmaceutical policy issues in Canada and to translate them into research priorities using key informant interviews, stakeholder surveys and a deliberative workshop. Results: We found consensus on overarching policy goals: to provide all Canadians with equitable and sustainable access to necessary medicines. We also found widespread frustration that many key pharmaceutical policy issues in Canada — including improving prescription drug financing and pricing — have been persistent challenges owing to a lack of policy coordination. The coverage of extraordinarily costly medicines for serious conditions was identified as a rapidly emerging policy issue. Conclusion: Targeted research and knowledge translation activities can help address key policy issues and, importantly, challenges of policy coordination in Canada and thereby reduce inequity and inefficiency in policy approaches and outcomes.

The last few years have seen considerable research expenditure on renewable fuel technologies. However, in many cases, the necessary sustained and long-term funding from the investment community has not been realized at a level needed to allow technologies to become reality. According to global consulting firm Deloitte's recent renewable energy report (http://www.deloitte.com/energypredictions2012), many renewable energy projects stalled or were not completed because of issues including the global economy, the state of government finances, difficulties in funding and regulatory uncertainty. This investigation concentrates on the funding aspect and explores the perceived barriers and enablers to renewable technologies within the investment and renewables community. Thematic analysis of 14 in-depth interviews with representatives from renewable energy producers, banks and investment companies identified key factors affecting the psychology of investor behaviour in renewables. Eight key issues are highlighted, including a range of barriers and enablers, the role of the government, balance between cost/risk, value/return on investment, investment time scales, personality/individual differences of investors and the level of innovation in the renewable technology. It was particularly notable that in the findings the role of the government was discussed more than other themes and generally in quite critical terms, highlighting the need to ensure consistency in government funding and policy and a greater understanding of how government decision-making happens. Specific findings such as these illustrate the value of crossing disciplinary boundaries and highlight potential further research. Behavioural science and economic psychology in particular have much to offer at the interface of other disciplines such as political science and financial economics. PMID:24427512

The scientific community is increasingly concerned with the proportion of published "discoveries" that are not replicated in subsequent studies. The field of rodent behavioral phenotyping was one of the first to raise this concern, and to relate it to other methodological issues: the complex interaction between genotype and environment; the definitions of behavioral constructs; and the use of laboratory mice and rats as model species for investigating human health and disease mechanisms. In January 2015, researchers from various disciplines gathered at Tel Aviv University to discuss these issues. The general consensus was that the issue is prevalent and of concern, and should be addressed at the statistical, methodological and policy levels, but is not so severe as to call into question the validity and the usefulness of model organisms as a whole. Well-organized community efforts, coupled with improved data and metadata sharing, have a key role in identifying specific problems and promoting effective solutions. Replicability is closely related to validity, may affect generalizability and translation of findings, and has important ethical implications. Copyright © 2018 The Authors.

Should we genetically test everyone for haemochromatosis?

PubMed

Allen, K; Williamson, R

1999-04-01

The increasing availability of DNA-based diagnostic tests has raised issues about whether these should be applied to the population at large in order to identify, treat or prevent a range of diseases. DNA tests raise concerns in the community for several reasons. There is the possibility of stigmatisation and discrimination between those who test positive and those who don't. High-risk individuals may be identified for whom no proven effective intervention is possible, or conversely may test "positive" for a disease that does not eventuate. Controversy concerning prenatal diagnosis and termination of affected pregnancies may arise. Haemochromatosis, however, is a disease that is not only treatable but also preventable if those at high risk are identified presymptomatically. This paper will identify and discuss key issues regarding DNA-based population screening for haemochromatosis, and argue that population-based genetic screening for haemochromatosis should be supported when a number of contentious issues are addressed. In the context of a health system with limited resources haemochromatosis is the paradigm of a disorder where there is an ethical and clinical imperative to encourage presymptomatic DNA testing for all in ethnically relevant communities.

Molecular Oxygen in the Thermosphere: Issues and Measurement Strategies

Picone, J. M.; Hedin, A. E.; Drob, D. P.; Meier, R. R.; Bishop, J.; Budzien, S. A.

2002-05-01

We review the state of empirical knowledge regarding the distribution of molecular oxygen in the lower thermosphere (100-200 km), as embodied by the new NRLMSISE-00 empirical atmospheric model, its predecessors, and the underlying databases. For altitudes above 120 km, the two major classes of data (mass spectrometer and solar ultraviolet [UV] absorption) disagree significantly regarding the magnitude of the O2 density and the dependence on solar activity. As a result, the addition of the Solar Maximum Mission (SMM) data set (based on solar UV absorption) to the NRLMSIS database has directly impacted the new model, increasing the complexity of the model's formulation and generally reducing the thermospheric O2 density relative to MSISE-90. Beyond interest in the thermosphere itself, this issue materially affects detailed models of ionospheric chemistry and dynamics as well as modeling of the upper atmospheric airglow. Because these are key elements of both experimental and operational systems which measure and forecast the near-Earth space environment, we present strategies for augmenting the database through analysis of existing data and through future measurements in order to resolve this issue.

PM₂.₅ opened a door to public participation addressing environmental challenges in China.

PubMed

Huang, Ganlin

2015-02-01

China has long been regarded as a centralized society where the public has little influence on decision-making. Such a top-down management scheme is perceived as a major obstacle to address complicated environment issues. The recent public campaign in China to urge creation of a nationwide PM₂.₅ monitoring network and mitigation plan provides an unprecedented case of how the public participated and influenced policy-making in a centralized society. This paper reviews key incidents in the campaign chronologically. Here we identify information technology, public awareness of air quality's health impacts and the fact air quality affects everyone as public goods as the major factors promoting public participation. This case demonstrates that public participation can happen in a centralized, top-down society such as China. Continued environmental deterioration may stimulate similar campaigns for other issues. We anticipate this essay to be a starting point for more studies on how environmental issues stimulate incremental social change by making people involved in decision-making process, especially in societies where they are rarely able to do so.

2017-12-19

The eHealth Literacy Scale (eHEALS) has been widely adopted by researchers to understand how eHealth literacy can be put into context. eHealth researchers need to know how to promote positive health behavior changes across college students, given the importance of the Internet to acquire and use health information. The American College Health Association identified a set of key health issues that affect college students today. By understanding how eHEALS might be related to college students' maintenance of their health and their use of online health resources, researchers will be provided with a better understanding of eHealth literacy and its pragmatic implications for health campaigns and future interventions. The goal of the study was to examine what eHEALS reveals about college student health behaviors identified by the American College Health Association. To understand college student current health maintenance and their intentions to maintain their health and use online resources, the theory of planned behavior was used as the theoretical framework for the study. Data were collected via a survey of 422 college students that included the eHEALS measure and questions about health issues based on the recommendations of the American College Health Association. These questions asked about college student current health, subsequent use of online health resources, and their intention to maintain their health and make use of such resources in the future. eHEALS was positively and significantly associated with all 8 areas of health issues identified by the American College Health Association for college student current maintenance of health and use of online health resources and for future intention of health maintenance and use of online resources. Key issues that emerged with eHealth literacy were maintaining safe sex practices and seeking out related information, seeking out information on an exercise regime, information on vaccinations, and maintaining a balanced diet. These results suggest several areas that may be targeted for future health campaigns toward college students. In addition, eHEALS was found to be a useful instrument for college students in the United States. Lastly, these results point to a need to deliver targeted information to college students, particularly since eHEALS captures literacy based on positively phrased items. ©Rebecca Katherine Britt, William Bart Collins, Kari Wilson, Georgiann Linnemeier, Andrew Mark Englebert.

While immunization coverage rates for childhood routine vaccines in Hong Kong are almost 100%, the uptake rates of optional vaccines remain suboptimal. Understanding parental decision-making for children's vaccination is important, particularly among minority groups who are most vulnerable and underserved. This study explored how a subsample of new immigrant mothers from mainland China, a rapidly-growing subpopulation in Hong Kong, made decisions on various childhood and adolescent vaccines for their offspring, and identified key influences affecting their decision making. Semi-structured in-depth interviews were conducted with 23 Chinese new immigrant mothers recruited by purposive sampling. All interviews were audio-taped, transcribed and analyzed using a Grounded Theory approach. Participants' conversation revealed five underlying themes which influenced parents' vaccination decision-making: (1) Institutional factors, (2) Insufficient vaccination knowledge and advice, (3) Affective impacts on motivation, (4) Vaccination barriers, and (5) Social influences. The role of social norms appeared overwhelmingly salient influencing parents' vaccination decision making. Institutional factors shaped parent's perceptions of vaccination necessity. Fear of vaccine-targeted diseases was a key motivating factor for parents adopting vaccination. Insufficient knowledge about vaccines and targeted diseases, lack of advice from health professionals and, if provided, suspicions regarding the motivations for such advice were common issues. Vaccination cost was a major barrier for many new immigrant parents. Social norms play a key role influencing parental vaccination decision-making. Insight gained from this study will help inform healthcare providers in vaccination communication and policymakers in future vaccination programme.

Childhood malnutrition is a major public health issue. Multidisciplinary approach for Improvement of Nutritional Status of Children in Iran was implemented in order to reduce malnutrition among children. This study aimed to evaluate the implementation aspect of the program and to explore key informants' perceptions and experience regarding the factors affected its implementation. Data were collected through the review of secondary data and semistructured interviews at national, province, and local levels. Four layers of key informants were selected purposefully for interviewing, including policymakers, senior nutrition officers, head of Hygiene, Remedy and Insurance Affairs in Imam Khomeini Relief Foundation, and community health workers. Qualitative content analysis was carried out based on Supporting the Use of Research Evidence framework and Tailored Implementation for Chronic Diseases' checklist to interpret the viewpoints of the study participants. Results showed that the program had successes in improving mother's knowledge on health, nutrition, and child care through health system and increased families' access to food, but there were some aspects that affected program's implementation. Some of these factors are the lack of clarity in the program's protocol and indicators, human shortage and inadequate financial resources, poor facilities, inattention to staff motivation, insufficient commitment among different sections, poor communication and supervision among different executive sections, and program protocols designing regardless of practical condition. Based on the results, top-down approach in policymaking and inadequate financial and human resources were responsible for most of the challenges encountered in the implementation.

Interplay between Public Attention and Public Emotion toward Multiple Social Issues on Twitter

This study aims to elucidate the intricate interplay between public attention and public emotion toward multiple social issues. A theoretical framework is developed based on three perspectives including endogenous affect hypothesis, affect transfer hypothesis, and affective intelligence theory. Large-scale longitudinal data with 265 million tweets on five social issues are analyzed using a time series analytical approach. Public attention on social issues can influence public emotion on the issue per se. Social issues interact with one another to attract public attention in both cooperative and competitive ways. Instead of a direct transfer from public emotion to public attention, the public emotion toward a social issue moderates the interaction between the issue and other issue(s). PMID:28081117

How Japanese students reason about agricultural biotechnology.

PubMed

Maekawa, Fumi; Macer, Darryl

2004-10-01

Many have claimed that education of the ethical issues raised by biotechnology is essential in universities, but there is little knowledge of its effectiveness. The focus of this paper is to investigate how university students assess the information given in class to make their own value judgments and decisions relating to issues of agricultural biotechnology, especially over genetically modified organisms (GMOs). Analysis of homework reports related with agricultural biotechnology after identification of key concepts and ideas in each student report is presented. The ideas were sorted into different categories. The ideas were compared with those in the reading materials using the same categories. These categories included: concern about affects on humans, affects on the environment, developing countries and starvation, trust in industry, responsibility of scientists, risk perception, media influence, need for (international) organizations or third parties, and information dissemination. What was consistent through the different years was that more than half of the students took a "neutral" position. A report was scored as "neutral" when the report included both the positive and negative side of an issue, or when the student could not make a definite decision about the use of GMOs and GM food. While it may be more difficult to defend a strong ''for" or "against" position, some students used logical arguments successfully in doing so. Sample comments are presented to depict how Japanese students see agricultural technology, and how they value its application, with comparisons to the general social attitudes towards biotechnology.

The Danube River-Danube Delta-Black Sea (DBS) region has witnessed major political, social and economic changes during the past three decades, which have profoundly affected the riverine, coastal and marine systems, their water management situation and the development of related research programmes. We reviewed the research activities in the DBS system of the past twenty years to determine the main funding bodies and to assess key research areas and how they varied over time and geographic region. As data basis we used a metadatabase filled with 478 projects addressing environmental and water management issues in the Danube River Basin, covering also the Danube Delta and the north-western Black Sea. As overall outcome extensive research efforts in the field of water management could be proven for the past two decades, despite the tumultuous times of political and economic transformations. One of the main findings was that EU funded projects played a key role for the development of transboundary research collaboration and were also the scientifically most productive one's. Historically, nutrient pollution was the main problem addressed, shifting to pollution in a broader sense and hydromorphological alterations in recent years. The newly arising challenges of climate change impacts and sediment management became important research questions in the last years, too. Most research was performed in the thematic field of navigation, followed by restoration and biodiversity issues. To meet all of the already identified and newly emerging challenges in the DBS System, cross-border and integrated (river-delta-sea) research activities are of major importance and have to be further promoted. We thus suggest drawing up a regional DBS Research Agenda linked to key challenges in water management to strengthen research collaboration and advance targeted scientific projects, an approach fostering also the scientific capacity in the region.

Ethics guidelines, health research and Indigenous Australians.

2003-02-01

In this paper we overview the findings of a literature review that was undertaken to guide the revision of the Guidelines on Ethical Matters in Aboriginal and Torres Strait Islander Health Research (NH&MRC, 1991). The literature reviewed, in general, supported the development of specific research guidelines for Aboriginal and Torres Strait Islander contexts. The findings of this review were analysed thematically, and a number of key issues were identified for consideration in the review process. We present a summary of these key issues. In the final section of the paper we consider in more detail two of the key issues raised in the review process (the assessment of relevance or benefit of proposed research; and the process of consultation and negotiation of collective consent) in order to critically consider how these issue should be engaged in revised guidelines. On the basis of this analysis, it is our contention that specific guidelines on key issues are limited to the extent to which they can anticipate all possible research contexts. In order to address this problem, and guide researchers, guidelines should also explicitly outline the values, from an Aboriginal and Torres Islander perspective that are foundational to an ethical research process.

Statistical issues on the analysis of change in follow-up studies in dental research.

Blance, Andrew; Tu, Yu-Kang; Baelum, Vibeke; Gilthorpe, Mark S

2007-12-01

To provide an overview to the problems in study design and associated analyses of follow-up studies in dental research, particularly addressing three issues: treatment-baselineinteractions; statistical power; and nonrandomization. Our previous work has shown that many studies purport an interacion between change (from baseline) and baseline values, which is often based on inappropriate statistical analyses. A priori power calculations are essential for randomized controlled trials (RCTs), but in the pre-test/post-test RCT design it is not well known to dental researchers that the choice of statistical method affects power, and that power is affected by treatment-baseline interactions. A common (good) practice in the analysis of RCT data is to adjust for baseline outcome values using ancova, thereby increasing statistical power. However, an important requirement for ancova is there to be no interaction between the groups and baseline outcome (i.e. effective randomization); the patient-selection process should not cause differences in mean baseline values across groups. This assumption is often violated for nonrandomized (observational) studies and the use of ancova is thus problematic, potentially giving biased estimates, invoking Lord's paradox and leading to difficulties in the interpretation of results. Baseline interaction issues can be overcome by use of statistical methods; not widely practiced in dental research: Oldham's method and multilevel modelling; the latter is preferred for its greater flexibility to deal with more than one follow-up occasion as well as additional covariates To illustrate these three key issues, hypothetical examples are considered from the fields of periodontology, orthodontics, and oral implantology. Caution needs to be exercised when considering the design and analysis of follow-up studies. ancova is generally inappropriate for nonrandomized studies and causal inferences from observational data should be avoided.

Flashes and floaters are common ophthalmic issues for which patients may initially present to their general practitioner. It may be a sign of benign, 
age-related changes of the vitreous or more serious retinal detachment. This article provides a guide to the assessment and management of a patient presenting with flashes and floaters. Although most patients presenting with flashes and floaters have benign 
age-related changes, they must be referred to an ophthalmologist to rule out sight-threatening conditions. Key examination features include the nature of the flashes and floaters, whether one or both eyes are affected and changes in visual acuity or visual field.

Individuals who are incarcerated experience disparities in mental health, warranting study by nurse researchers. However, nurse researchers' unfamiliarity with the jail environment may pose a barrier to conducting research with this vulnerable population. The current article presents an account of the planning and implementation needed to study perceived health and gambling behavior in county jail inmates. The challenges and rewards of research that aim to better understand the mental health issues affecting this population are also identified. Developing relationships with jail personnel and understanding the incarcerated population and their surroundings are key to conducting research in this environment.

On the Compliance of Simbol-X Mirror Roughness with its Effective Area Requirements

NASA Astrophysics Data System (ADS)

Spiga, D.; Basso, S.; Cotroneo, V.; Pareschi, G.; Tagliaferri, G.

2009-05-01

Surface microroughness of X-ray mirrors is a key issue for the angular resolution of Simbol-X to comply with the required one (<20 arcsec at 30 keV). The maximum tolerable microroughness for Simbol-X mirrors, in order to satisfy the required imaging capability, has already been derived in terms of its PSD (Power Spectral Density). However, also the Effective Area of the telescope is affected by the mirror roughness. In this work we will show how the expected effective area of the Simbol-X mirror module can be computed from the roughness PSD tolerance, checking its compliance with the requirements.

The accountability of nonprofit hospitals: lessons from Maryland's community benefit reporting requirements.

PubMed

Gray, Bradford H; Schlesinger, Mark

2009-01-01

Under Internal Revenue Service requirements, nonprofit hospitals will begin filing new community benefit reports in 2010. Maryland has had similar requirements since 2004. This paper, based on interviews at 20 hospitals, describes how Maryland's requirements affected hospitals and their activities. Increases in reported community benefit expenditures since the program began are due to both changes in activities and better data capture. Charity care accounts for one-third of community benefit dollars. A key distinction concerns whether hospitals take an accounting or managerial approach to community benefit. The Maryland experience suggests the issues that will arise when the national requirements are implemented.

How do we make models that are useful in understanding partial epilepsies?

PubMed

Prince, David A

2014-01-01

The goals of constructing epilepsy models are (1) to develop approaches to prophylaxis of epileptogenesis following cortical injury; (2) to devise selective treatments for established epilepsies based on underlying pathophysiological mechanisms; and (3) use of a disease (epilepsy) model to explore brain molecular, cellular and circuit properties. Modeling a particular epilepsy syndrome requires detailed knowledge of key clinical phenomenology and results of human experiments that can be addressed in critically designed laboratory protocols. Contributions to understanding mechanisms and treatment of neurological disorders has often come from research not focused on a specific disease-relevant issue. Much of the foundation for current research in epilepsy falls into this category. Too strict a definition of the relevance of an experimental model to progress in preventing or curing epilepsy may, in the long run, slow progress. Inadequate exploration of the experimental target and basic laboratory results in a given model can lead to a failed effort and false negative or positive results. Models should be chosen based on the specific issues to be addressed rather than on convenience of use. Multiple variables including maturational age, species and strain, lesion type, severity and location, latency from injury to experiment and genetic background will affect results. A number of key issues in clinical and basic research in partial epilepsies remain to be addressed including the mechanisms active during the latent period following injury, susceptibility factors that predispose to epileptogenesis, injury - induced adaptive versus maladaptive changes, mechanisms of pharmaco-resistance and strategies to deal with multiple pathophysiological processes occurring in parallel.

Impacts of Permafrost on Infrastructure and Ecosystem Services

Trochim, E.; Schuur, E.; Schaedel, C.; Kelly, B. P.

2017-12-01

The Study of Environmental Arctic Change (SEARCH) program developed knowledge pyramids as a tool for advancing scientific understanding and making this information accessible for decision makers. Knowledge pyramids are being used to synthesize, curate and disseminate knowledge of changing land ice, sea ice, and permafrost in the Arctic. Each pyramid consists of a one-two page summary brief in broadly accessible language and literature organized by levels of detail including synthesizes and scientific building blocks. Three knowledge pyramids have been produced related to permafrost on carbon, infrastructure, and ecosystem services. Each brief answers key questions with high societal relevance framed in policy-relevant terms. The knowledge pyramids concerning infrastructure and ecosystem services were developed in collaboration with researchers specializing in the specific topic areas in order to identify the most pertinent issues and accurately communicate information for integration into policy and planning. For infrastructure, the main issue was the need to build consensus in the engineering and science communities for developing improved methods for incorporating data applicable to building infrastructure on permafrost. In ecosystem services, permafrost provides critical landscape properties which affect basic human needs including fuel and drinking water availability, access to hunting and harvest, and fish and wildlife habitat. Translating these broad and complex topics necessitated a systematic and iterative approach to identifying key issues and relating them succinctly to the best state of the art research. The development of the knowledge pyramids provoked collaboration and synthesis across distinct research and engineering communities. The knowledge pyramids also provide a solid basis for policy development and the format allows the content to be regularly updated as the research community advances.

Patient-centered care: the key to cultural competence.

PubMed

Epner, D E; Baile, W F

2012-04-01

Much of the early literature on 'cultural competence' focuses on the 'categorical' or 'multicultural' approach, in which providers learn relevant attitudes, values, beliefs, and behaviors of certain cultural groups. In essence, this involves learning key 'dos and don'ts' for each group. Literature and educational materials of this kind focus on broad ethnic, racial, religious, or national groups, such as 'African American', 'Hispanic', or 'Asian'. The problem with this categorical or 'list of traits' approach to clinical cultural competence is that culture is multidimensional and dynamic. Culture comprises multiple variables, affecting all aspects of experience. Cultural processes frequently differ within the same ethnic or social group because of differences in age cohort, gender, political association, class, religion, ethnicity, and even personality. Culture is therefore a very elusive and nebulous concept, like art. The multicultural approach to cultural competence results in stereotypical thinking rather than clinical competence. A newer, cross cultural approach to culturally competent clinical practice focuses on foundational communication skills, awareness of cross-cutting cultural and social issues, and health beliefs that are present in all cultures. We can think of these as universal human beliefs, needs, and traits. This patient centered approach relies on identifying and negotiating different styles of communication, decision-making preferences, roles of family, sexual and gender issues, and issues of mistrust, prejudice, and racism, among other factors. In the current paper, we describe 'cultural' challenges that arise in the care of four patients from disparate cultures, each of whom has advanced colon cancer that is no longer responding to chemotherapy. We then illustrate how to apply principles of patient centered care to these challenges.

[Progresses of alpine treeline formation mechanism.

Alpine treelines represent one of the most distinct vegetation boundaries between canopy closed montane forest and treeless alpine vegetation. This transitional ecotone is highly sensitive to global and regional climate change and is considered as an ideal indicator of such changes. Treeline studies have evolved from morphological description to various hypotheses of treeline formation. Although individual hypothesis may provide reasonable explanation locally, a generalized hypothesis that is applicable on the global scale is still lacking. Temperature is considered the limited factor controlling the distribution of alpine treeline as low temperature restricts biochemical processes of tree growth. However, which particular biochemical processes are affected by low temperature remains unknown. This paper summarized the mechanisms of treeline formation with a focus on how low temperature affects photosynthesis characteristics, nutrient characteristics, non-structural carbohydrate (NSC) and antioxidant system. We also reviewed the key issues and future perspectives in treeline research.

The evolutionary and ecological consequences of animal social networks: emerging issues.

Kurvers, Ralf H J M; Krause, Jens; Croft, Darren P; Wilson, Alexander D M; Wolf, Max

2014-06-01

The first generation of research on animal social networks was primarily aimed at introducing the concept of social networks to the fields of animal behaviour and behavioural ecology. More recently, a diverse body of evidence has shown that social fine structure matters on a broader scale than initially expected, affecting many key ecological and evolutionary processes. Here, we review this development. We discuss the effects of social network structure on evolutionary dynamics (genetic drift, fixation probabilities, and frequency-dependent selection) and social evolution (cooperation and between-individual behavioural differences). We discuss how social network structure can affect important coevolutionary processes (host-pathogen interactions and mutualisms) and population stability. We also discuss the potentially important, but poorly studied, role of social network structure on dispersal and invasion. Throughout, we highlight important areas for future research.

Convergent ethical issues in HIV/AIDS, tuberculosis and malaria vaccine trials in Africa: Report from the WHO/UNAIDS African AIDS Vaccine Programme's Ethics, Law and Human Rights Collaborating Centre consultation, 10-11 February 2009, Durban, South Africa

PubMed Central

2010-01-01

Background Africa continues to bear a disproportionate share of the global HIV/AIDS, tuberculosis (TB) and malaria burden. The development and distribution of safe, effective and affordable vaccines is critical to reduce these epidemics. However, conducting HIV/AIDS, TB, and/or malaria vaccine trials simultaneously in developing countries, or in populations affected by all three diseases, is likely to result in numerous ethical challenges. Methods In order to explore convergent ethical issues in HIV/AIDS, TB and malaria vaccine trials in Africa, the Ethics, Law and Human Rights Collaborating Centre of the WHO/UNAIDS African AIDS Vaccine Programme hosted a consultation on the Convergent Ethical Issues in HIV/AIDS, TB and Malaria Vaccine Trials in Africa in Durban, South Africa on the 10-11 February 2009. Results Key cross cutting ethical issues were prioritized during the consultation as community engagement; ancillary care obligations; care and treatment; informed consent; and resource sharing. Conclusion The consultation revealed that while there have been few attempts to find convergence on ethical issues between HIV/AIDS, TB and malaria vaccine trial fields to date, there is much common ground and scope for convergence work between stakeholders in the three fields.

The antecedents of identification: a rhetorical analysis of British Muslim activists' constructions of community and identity.

PubMed

Hopkins, Nick; Kahani-Hopkins, Vered

2004-03-01

This paper takes as its focus the perception of community. This is analysed through reference to the literature concerning the adoption of more inclusive, superordinate social categories. Whilst most research tends to focus on the consequences of these social categories for self and other perception, we focus on their antecedents. These are typically hypothesized to include such issues as the perception of the subordinate groups' common fate and factors affecting their perceptual differentiation (e.g. their similarity and entitativity). However, rather than conceiving of such issues as pre-given antecedent variables, we explore how these issues (and others) are actively constructed in and through discourse. More specifically, we explore how such issues are sites of contestation as activists with different political projects seek to construct quite different versions of the relevant superordinate community identity. Our data are qualitative and are drawn from contemporary debates amongst British Muslims concerning their relations with non-Muslim Britons and non-British Muslims across the globe. A key issue in these deliberations concerns the nature of British Muslims' identity and the superordinate identifications that best facilitate its expression and realization. We suggest that constructions of common fate, similarity, entitativity etc., far from being 'givens', are the means through which different definitions of Muslim identity are constructed and different forms of collective action mobilized.

"Everyone just keeps their eyes closed and their fingers crossed": sexual health communication among black parents and children in Nova Scotia, Canada.

Black Canadian youth remain disproportionally affected by an array of social and health issues, including sexually transmitted infections. While research exists in support of the involvement of parents as a key means to prevent or modify harmful behaviours among youth, less is known about how parent-child communication can serve as a prevention intervention strategy within Black families in Canada. This study explores sexual health communication between Black parents and youth in Nova Scotia and identifies facilitators, obstacles and issues that families face in dialoguing about sexual health. Focus groups and in-depth interview sessions were held with a diverse sample of parents of Black youth, health and education professionals, and Black youth in Nova Scotia, as part of a larger study aimed at exploring parent-child communication on sexual health and HIV. The research team worked in partnership with and received feedback from key informants and a community advisory committee throughout the various stages of this study. All sessions were audio-taped with permission and thematic analysis was carried out on the verbatim transcripts. Six key themes emerged from the data analysis in relation to parent-child communication within Black families in Nova Scotia: 1. the gendered nature of [sexual] health communication; 2. fear and uncertainty as obstacles; 3. open and honest dialogue from an early age as a facilitator; 4. media as both a catalyst and a barrier; 5. peers as a catalyst; and 6. time constraints as an obstacle. The findings of this study reveal that parent-child communication regarding sexual health promotion within Black families in Nova Scotia remains varied and is heavily affected by a myriad of intersecting determinants of health faced by Black youth and their parents. Health promotion interventions aimed at fostering and supporting parent-child communication on sexual health must simultaneously target both parents and youth and further, such efforts must engage a high level of cultural competency in order to better meet the needs of this population.

Health economics of screening for gynaecological cancers.

Kulasingam, Shalini; Havrilesky, Laura

2012-04-01

In this chapter, we summarise findings from recent cost-effectiveness analyses of screening for cervical cancer and ovarian cancer. We begin with a brief summary of key issues that affect the cost-effectiveness of screening, including disease burden, and availability and type of screening tests. For cervical cancer, we discuss the potential effect of human papilloma virus vaccines on screening. Outstanding epidemiological and cost-effectiveness issues are included. For cervical cancer, this includes incorporating the long-term effect of treatment (including adverse birth outcomes in treated women who are of reproductive age) into cost-effectiveness models using newly available trial data to identify the best strategy for incorporating human papilloma virus tests. A second issue is the need for additional data on human papilloma virus vaccines, such as effectiveness of reduced cancer incidence and mortality, effectiveness in previously exposed women and coverage. Definitive data on these parameters will allow us to update model-based analyses to include more realistic estimates, and also potentially dramatically alter our approach to screening. For ovarian cancer, outstanding issues include confirming within the context of a trial that screening is effective for reducing mortality and incorporating tests with high specificity into screening into screening algorithms for ovarian cancer.

Who reaps the benefits, who bears the risks? Comparative optimism, comparative utility, and regulatory preferences for mobile phone technology.

Although the issue of risk target (e.g., self, others, children) is widely acknowledged in risk perception research, its importance appears underappreciated. To date, most research has been satisfied with demonstrating comparative optimism, i.e., lower perceived risk for the self than others, and exploring its moderators, such as perceived controllability and personal exposure. Much less research has investigated how the issue of target may affect benefit perceptions or key outcomes such as stated preferences for hazard regulation. The current research investigated these issues using data from a public survey of attitudes toward mobile phone technology (N= 1,320). First, results demonstrated comparative optimism for this hazard, and also found moderating effects of both controllability and personal exposure. Second, there was evidence of comparative utility, i.e., users believed that the benefits from mobile phone technology are greater for the self than others. Third, and most important for policy, preferences for handset regulation were best predicted by perceptions of the risks to others but perceived benefits for the self. Results suggest a closer awareness of target can improve prediction of stated preferences for hazard regulation and that it would be profitable for future research to pay more attention to the issue of target for both risk and benefit perceptions.

Toward a More Usable Home-Based Video Telemedicine System: A Heuristic Evaluation of the Clinician User Interfaces of Home-Based Video Telemedicine Systems.

Telemedicine is the use of technology to provide and support health care when distance separates the clinical service and the patient. Home-based telemedicine systems involve the use of such technology for medical support and care connecting the patient from the comfort of their homes with the clinician. In order for such a system to be used extensively, it is necessary to understand not only the issues faced by the patients in using them but also the clinician. The aim of this study was to conduct a heuristic evaluation of 4 telemedicine software platforms-Doxy.me, Polycom, Vidyo, and VSee-to assess possible problems and limitations that could affect the usability of the system from the clinician's perspective. It was found that 5 experts individually evaluated all four systems using Nielsen's list of heuristics, classifying the issues based on a severity rating scale. A total of 46 unique problems were identified by the experts. The heuristics most frequently violated were visibility of system status and Error prevention amounting to 24% (11/46 issues) each. Esthetic and minimalist design was second contributing to 13% (6/46 issues) of the total errors. Heuristic evaluation coupled with a severity rating scale was found to be an effective method for identifying problems with the systems. Prioritization of these problems based on the rating provides a good starting point for resolving the issues affecting these platforms. There is a need for better transparency and a more streamlined approach for how physicians use telemedicine systems. Visibility of the system status and speaking the users' language are keys for achieving this. ©Sruthy Agnisarman, Shraddhaa Narasimha, Kapil Chalil Madathil, Brandon Welch, FNU Brinda, Aparna Ashok, James McElligott.

Trade in health-related services.

2009-02-14

The supervision of a domestic health system in the context of the trade environment in the 21st century needs a sophisticated understanding of how trade in health services affects, and will affect, a country's health system and policy. This notion places a premium on people engaged in the health sector understanding the importance of a comprehensive outlook on trade in health services. However, establishment of systematic comparative data for amounts of trade in health services is difficult to achieve, and most trade negotiations occur in isolation from health professionals. These difficulties compromise the ability of a health system to not just minimise the risks presented by trade in health services, but also to maximise the opportunities. We consider these issues by presenting the latest trends and developments in the worldwide delivery of health-care services, using the classification provided by the World Trade Organization for the General Agreement on Trade in Services. This classification covers four modes of service delivery: cross-border supply of services; consumption of services abroad; foreign direct investment, typically to establish a new hospital, clinic, or diagnostic facility; and the movement of health professionals. For every delivery mode we discuss the present magnitude and pattern of trade, main contributors to this trade, and key issues arising.

To identify the key favorable issues, showing a high degree of job satisfaction, and also the adverse issues that may affect the work performance among medical assistants. This research is a type of inquiry-based opinion survey carried out by administering a self-managed, anonymous questionnaire, consisting of five sections with 25 items. The study group included 175 medical assistants from all specialties, working in public hospitals in the city of Iasi, who answered the questionnaires. A number of 167 subjects have responded, the return rate being of 95.4%. The respondents were asked to indicate the amount of agreement or disagreement on a typical five-level Likert scale. The study has identified some positive aspects: positive perception of the medical assistant profession (76.6%); concern about personal growth and career development (86.3%); good rel ationships established with other colleagues (71.2%), and some negative aspects: inappropriate work conditions and equipments (70%); the income compared to the volume of work was perceived by majority as an important source of dissatisfaction (80.8%); willingness to work abroad (53.9%). The findings of the present research focused on the variables of job satisfaction in the medical assistant profession and should be a real concern for managers, because the job dissatisfaction may affect the employee's productivity.

Rayleigh-Taylor and Richtmyer-Meshkov Instabilities in Turbulent Regime

NASA Astrophysics Data System (ADS)

Dimonte, G.

1998-11-01

The Rayleigh-Taylor instability (RTI) and its shock driven analog, the Richtmyer-Meshkov instability (RMI), affect a wide variety of important phenomena from sub-terrainian to astrophysical environments. The ``fluids" are equally varied from plasmas and magnetic fields to elastic-plastic solids. In most applications, the instabilities occur with a complex acceleration history and evolve to a highly nonlinear state, making the theoretical description formidable. We will link the fluid and plasma regimes while describing the theoretical issues and basic experiments in different venues to isolate key physics issues. RMI experiments on the Nova laser investigate the affects of compressibility with strong radiatively driven shocks (Mach > 10) in near solid density plasmas of sub-millimeter scale. The growth of single sinusoidal and random 3-D perturbations are measured using backlit radiography. RTI experiments with the Linear Electric Motor (LEM) are conducted with a variety of acceleration (<< 10^4 m/s^2) histories and fluids of 10 cm scale. Turbulent RTI experiments with high Reynolds number liquids show self-similar growth which is characterized with laser induced fluorescence. LEM experiments with an elastic-plastic material (yogurt) exhibit a critical wavelength and amplitude for instability. The experimental results will be compared with linear and nonlinear theories and hydrodynamic simulations.

HIV/AIDS in Asia.

Ruxrungtham, Kiat; Brown, Tim; Phanuphak, Praphan

HIV (ie, HIV-1) epidemics in Asia show great diversity, both in severity and timing. But epidemics in Asia are far from over and several countries including China, Indonesia, and Vietnam have growing epidemics. Several factors affect the rate and magnitude of growth of HIV prevalence, but two of the most important are the size of the sex worker population and the frequency with which commercial sex occurs. In view of the present state of knowledge, even countries with low prevalence of infection might still have epidemics affecting a small percentage of the population. Once HIV infection has become established, growing needs for care and treatment are unavoidable and even the so-called prevention-successful countries of Thailand and Cambodia are seeing burgeoning care needs. The manifestations of HIV disease in the region are discussed with the aim of identifying key issues in medical management and care of HIV/AIDS. In particular, issues relevant to developing appropriate highly active antiretroviral treatment programmes in the region are discussed. Although access to antiretroviral therapy is increasing globally, making it work effectively while simultaneously expanding prevention programmes to stem the flow of new infections remains a real challenge in Asia. Genuine political interest and commitment are essential foundations for success, demanding advocacy at all levels to drive policy, mobilise sufficient resources, and take effective action.

The Power Behind the Controversy: Understanding Local Policy Elites' Perceptions on the Benefits and Risks Associated with High Voltage Power Line Installation in the State of Arkansas

NASA Astrophysics Data System (ADS)

Moyer, Rachael M.

Following a proposal for the installation of high voltage power lines in northwest Arkansas, a controversial policy debate emerged. Proponents of the transmission line argue that such an installation is inevitable and necessary to efficiently and reliably support the identified electric load in the region. Opponents claim that the lines will degrade the natural environment and hamper the tourism-based local economy in affected regions, notably in Ozark Mountain areas. This study seeks to understand how local policy elites perceive the benefits and risks associated with proposed transmission lines, which is a critical step in comprehending the formation and changes of related government policies. First, based upon the dual process theory of judgment, this study systematically investigates the triadic relationships between (a) more profound personal value predispositions, (b) affects and feelings, and (c) perceived benefits and risks related to the proposed installation of high voltage power lines among local policy elites in the state of Arkansas. Next, this study focuses more specifically on the role of value predispositions, specific emotional dimensions of affect heuristics, and perceptions pertaining to high voltage power line risks and benefits. Using original data collected from a statewide Internet survey of 420 local leaders and key policymakers about their opinions on the related issues, other factors claimed by previous literature, including trust, knowledge level, and demographic characteristics are considered. Analytical results suggest that grid-group cultural predispositions, as deeply held core values within local policy elites' individual belief systems, both directly and indirectly -- through affective feelings -- shape perceived utility associated with the installation of high voltage power lines. Recognizing that risk perceptions factor into policy decisions, some practical considerations for better designing policy addressing controversial issues of this nature.
