  1. CURRENT ISSUES FACING THE INTRODUCTION OF HUMAN PAPILLOMAVIRUS VACCINE IN MALAYSIA

    Directory of Open Access Journals (Sweden)

    I-Ching Sam

    2007-01-01

    Full Text Available Certain human papillomavirus (HPV types are strongly associated with cervical cancer. Recently-described effective vaccines against these HPV types represent a great medical breakthrough in preventing cervical cancer. In Malaysia, the vaccine has just received regulatory approval. We are likely to face similar barriers to implementing HPV vaccination as reported by countries where vaccination has been introduced. Most women have poor understanding of HPV and its link to cervical cancer. Physicians who will be recommending HPV vaccines may not have extensive knowledge or experience with HPV-related disease. Furthermore, a vaccine against a sexually-transmitted infection may elicit negative reactions from potential recipients or their carers, particularly in a conservative society. Given the high cost of the vaccine, reaching the most vulnerable women is a concern. To foster broad acceptance of HPV vaccine, education must be provided to health care providers, parents and young women about the risks of HPV infection and the benefits of vaccination.

  2. Nuclear power faces up to competition. A textbook on current controversial issues

    International Nuclear Information System (INIS)

    Goering, R.W.; Oesterwind, D.

    1995-01-01

    Nuclear power plants should face up to competition in the energy sector, and nuclear power reactor technology should at last be discussed without bias. The criteria to be applied are: environmental effects, availability, economics, safety and general acceptance. For decades now nuclear power plant operation has been proving to meet the first three of the above criteria. But although the engineered safety concepts and the available operating data proved successful and reliable, the safety philosophy underlying nuclear reactor technology still could not win general acceptance among the population. There have been considerable advances in engineered nuclear safety over the last few years. Reactors have been designed on the basis of a novel safety philosophy. Such novel concepts deserve a new approach for assessment, taking into account the worldwide population explosion, increasing energy consumption, and rising environmental hazards. The book in hand reviews and explains the advanced safety concepts, so that readers can get insight into the safety qualities of novel reactor types and thus criteria for novel assessment. (orig.)

    While the effects of sleep loss on performance have previously been reviewed, the effects of disturbed sleep on recovery after exercise are less reported. Specifically, the interaction between sleep and physiological and psychological recovery in team-sport athletes is not well understood. Accordingly, the aim of the current review was to examine the current evidence on the potential role sleep may play in postexercise recovery, with a tailored focus on professional team-sport athletes. Recent studies show that team-sport athletes are at high risk of poor sleep during and after competition. Although limited published data are available, these athletes also appear particularly susceptible to reductions in both sleep quality and sleep duration after night competition and periods of heavy training. However, studies examining the relationship between sleep and recovery in such situations are lacking. Indeed, further observational sleep studies in team-sport athletes are required to confirm these concerns. Naps, sleep extension, and sleep-hygiene practices appear advantageous to performance; however, future proof-of-concept studies are now required to determine the efficacy of these interventions on postexercise recovery. Moreover, more research is required to understand how sleep interacts with numerous recovery responses in team-sport environments. This is pertinent given the regularity with which these teams encounter challenging scenarios during the course of a season. Therefore, this review examines the factors that compromise sleep during a season and after competition and discusses strategies that may help improve sleep in team-sport athletes.

    In this contribution we briefly review some of the current issues and promises for the future by asteroseismology. We are entering a new phase in this field driven by the wealth of data that has been collected and data that will soon be available for asteroseismology across the HR Diagram. Major difficulties in the descriptions of stellar interiors that arose in the second half of the 20th century may now be in part addressed and solved (this is the expectation{exclamation_point}) by asteroseismology with unprecedented precision. In this contribution we list some of the key open questions in stellar physics, the seismic data we expect to collect in the near future, and some techniques that will provide the tools to connect data and models.

    2007-02-07

    These colloquium proceedings will be valuable, the blurb says, for graduate students and researchers in cosmology and theoretical astrophysics. Specifically, the book 'looks at both the strengths and weaknesses of the current big bang model in explaining certain puzzling data' and gives a 'comprehensive coverage of the expanding field of cosmology'. The reality is rather different. Conference proceedings rarely compare in value with a solid monograph or good review articles, and Current Issues in Cosmology is no exception. The colloquium was convened by the two editors, who have both long harboured doubts about the big bang, and was held in Paris in June 2004. The proceedings contain 19 presented papers and relatively brief summary comments by four panel speakers. The questions and answers at the end of each talk and a general discussion at the end were recorded and transcribed but contain little of interest. The nature of the colloquium is indicated by panellist Francesco Bertola's comment: 'While in the 1950s it was possible to speak of rival theories in cosmology, now the big-bang picture has no strong rivals. This is confirmed by the fact that out of 1500 members of the IAU Division VIII (Galaxies and the Universe) only a dozen, although bright people, devote their time to the heterodox views.' This was largely a platform for them to give their views. At least half of the dozen, all the 'usual suspects', were present: Geoffery and Margaret Burbidge, Jayant Narlikar, Halton Arp, Chandra Wickramasinghe and, in spirit only but playing a role somewhat like the ghost of Hamlet's father, the late Fred Hoyle. Doubters presented 12 of the 19 papers. Orthodoxy should certainly be challenged and the sociology of science questioned, but I found two main problems with this book. The papers putting the orthodox view are too short, even perfunctory. The most that a serious graduate student would get out of them is a reference

    To review the epidemiology, mycology, clinical features and diagnosis, current pharmacotherapy, and pharmacoeconomics of onychomycosis. We conducted a MEDLINE search from 1966 to May 1997. References from these articles, manufacturers of the discussed antimycotics, and relevant abstracts from recent dermatology conferences were used to collect pertinent data. Data were obtained from published controlled studies and case reports. In the pharmacotherapy section, the most weight was placed on fully reported, randomized, controlled comparative trials, but abstracts and case series were included when well-controlled studies were unavailable. Onychomycosis is a common nail disorder that has a substantial impact on patients' quality of life. It is most commonly caused by dermatophytes, but yeasts and molds can also be involved. Diagnosis is made through clinical presentation, potassium hydroxide preparations, and culture of tissue/nail samples. Griseofulvin was the drug of choice for many years, but its low cure rates and the development of newer, more effective drugs made it fall out of favor. Current therapeutic alternatives include fluconazole, itraconazole, and terbinafine. Data on the use of fluconazole are limited to case series and reports. Continuous dosing of itraconazole and terbinafine are well-proven therapies. New data are becoming available on the use of pulse itraconazole dosing, which has recently been approved by the Food and Drug Administration for fingernail infections. These drugs are well tolerated, but attention to drug interactions is necessary with the azoles. Currently, continuous terbinafine appears to be the most cost-effective drug for dermatophyte onychomycosis.

  13. Clopidogrel Resistance: Current Issues

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Antiplatelet agents are mainly used in the prevention and management of atherothrombotic complications. Dual antiplatelet therapy, combining aspirin and clopidogrel, is the standard care for patients having acute coronary syndromes or undergoing percutaneous coronary intervention according to the current ACC/AHA and ESC guidelines. But in spite of administration of dual antiplatelet therapy, some patients develop recurrent cardiovascular ischemic events especially stent thrombosis which is a serious clinical problem. Antiplatelet response to clopidogrel varies widely among patients based on ex vivo platelet function measurements. Clopidogrel is an effective inhibitor of platelet activation and aggregation due to its selective and irreversible blockade of the P2Y12 receptor. Patients who display little attenuation of platelet reactivity with clopidogrel therapy are labeled as low or nonresponders or clopidogrel resistant. The mechanism of clopidogrel resistance remains incompletely defined but there are certain clinical, cellular and genetic factors including polymorphisms responsible for therapeutic failure. Currently there is no standardized or widely accepted definition of clopidogrel resistance. The future may soon be realised in the routine measurement of platelet activity in the same way that blood pressure, cholesterol and blood sugar are followed to help guide the therapy, thus improving the care for millions of people. This review focuses on the methods used to identify patients with clopidogrel resistance, the underlying mechanisms, metabolism, clinical significance and current therapeutic strategies to overcome clopidogrel resistance.

  1. Reimbursement issues facing patients, providers, and payers.

    Science.gov (United States)

    Antman, K

    1993-11-01

    Escalating costs of health care delivery and the current constraints imposed by the federal budget deficit seriously threaten to compromise patient care and innovative biomedical research. Recent third-party refusal to cover some patients treated in protocols has had considerable impact on trial research. In addition, reimbursement for conventional care sometimes has been refused if delivered as part of a study (e.g., MOPP therapy versus ABVD therapy) or for an indication that is not specifically cited on the Food and Drug Administration label. Who should cover the patient care costs of patients participating in clinical trials? One approach would have patients cover these costs themselves. A second approach is the reinstitution of patient care costs into research grants. A third possibility is that the pharmaceutical industry support patient care costs of clinical research. Historically, hospital expenses of patients participating in studies have been paid by health insurance policies. In the absence of a clinical trial, many patients would be treated with Food and Drug Administration-approved therapies despite a lack of substantial benefit. Such marginal treatments are compensated by third-party payers routinely. The current system is arbitrary and expensive, compromises research and development, and equates new treatment with no treatment. By refusing to reimburse the patient care costs of investigational therapy, third-party carriers are, in fact, making medical decisions. There is a growing and legitimate concern that the pace of clinical research will be impeded significantly at a time when many exciting developments will be ready for clinical trials. The molecular steps in carcinogenesis are being documented rapidly for common malignancies, such as colon cancer. Immunologic, biologic, and hormonal approaches, and emerging technologies, such as marrow transplant or antibody toxin conjugates, already are being studied in the clinic. Health policy legislation

    Destruction and pollution of soil and ground water resources is probably the most important ecological problem facing the next generation. Checkable standards which certify healthy food products are required by the regulation on organic farming of the EU and should also be applied for conventional food production. Ecological food contains at least 95% of ingredients from an organic farming environment, without interference from pesticides, herbicides, fungicides or other chemicals and it is totally different from dietary, functional, enriched, fortified, probiotic food. Ecological food is tastier and contains more essential amino-acids, vitamin C, and micro-nutriments than usual food. Two major effects generated by choosing ecological food are the environmental protection and human' health improvement. Buying an ecological product represents the effect of a certain attitude. Children's nutrition starts with the most genuine ecological product: breast milk. Every parent should give to his child healthy and tasty food, for proper development. Decreasing artificial chemicals in the diet and the environment represents the first step to a healthier life.

  6. Researchers and experts faced with legal issues in radon affairs

    International Nuclear Information System (INIS)

    Massuelle, M.; Pirard, P.; Hubert, P.

    1998-01-01

    In France, radon has emerged as a public health issue mainly at the initiative of scientists. Public authorities are currently considering regulations but for a long time scientists faced the radon issue alone. As a consequence, scientists were involved and are still involved in producing knowledge, in informing about their results, in giving advice to various bodies and individuals, and in participating in the process of technical standardization. These functions are identified in the paper in order to sketch out a typology of different situations, formal and informal, in which researchers transformed into experts are called to collaborate. During their missions related to radon, experts are exposed to 'legal risks', particularly in terms of civil liability or 'professional' responsibility and even criminal responsibility. They face legal difficulties because their roles are not clearly defined. Such difficulties will be also described in this paper, because they are symptomatic of the lack of a legal framework for public scientific expertise. Indeed, there is a growing need to involve scientific experts in decision-making in the field of public health. At the same time, however, there is increased protest against the technocratic nature of public decision-making. We observe an increase in the attribution of blame and penal responsibility in French society, as shown in the 'contaminated blood' case in which not only blood suppliers but also public officials and now politicians have been or are being prosecuted. Radon, which is a domestic risk whose reduction relies entirely on homeowners, is sui generis in many ways. Nevertheless, in an analysis of scientists' roles/actions and of the legal difficulties they meet, radon can be used to illustrate the problems that arise as expertise is developed about new risks.

  7. Current uranium mill licensing issues

    International Nuclear Information System (INIS)

    Scarano, R.A.

    1977-01-01

    The problems encountered to insure environmentally safe mining and milling of uranium ores are reviewed. Emphasis is placed on the management of tailings resulting from milling operations. It is pointed out that although the concentration of radioactivity in the tailings is relatively low, control measures are necessary because of the large quantities involved and because of the long half-life of the parent radionuclides present. The major concerns with mill tailings are radon release to the atmosphere and isolation of the tailings from the human environment. Since it is anticipated that the amount of tailings created by the year 2000 will be more than an order of magnitude greater than the quantities that have been generated during the past 30 years, it is recommended that all mill tailings storage areas be located remote from public contact and in areas such that disruption and dispersion by natural forces and seepage of toxic materials into ground water systems are reduced to the maximum extent achievable. Technical issues that receive attention during the NRC licensing process for uranium mills and the preparation of environmental impact statements are discussed briefly

  8. Current bioethical issues in parasitology

    Directory of Open Access Journals (Sweden)

    Boury D.

    2008-09-01

    Full Text Available Parasitic diseases constitute the most common infections among the poorest billion people, entailing high mortality rates and leading to long-term infirmities and poverty. Although the setting-up of public health programs implies many ethical consequences, the range of specific questions in parasitology that can be attributed to bioethics remains, to a large extent, unexplored. From the present analysis, it emerged three main issues which characterize ethical stakes in parasitology: accounting the complexity of the field of intervention, putting the principle of justice into practice and managing the changing context of research. From the research angle, medical parasitology-mycology, as other biological disciplines, is undergoing tensions derived from biological reductionism. Thanks to its links with the history and philosophy of the sciences, bioethics can help to clarify them and to explain the growing hold that technologies have over scientific thinking. On the whole, researchers as well as clinicians are called on to assume a specific responsibility, proportional to their competence and their place in the making of scientific, health, economic and social decisions.

  13. NPT: the issues facing the Geneva PrepCom

    International Nuclear Information System (INIS)

    Hautecouverture, Benjamin

    2013-04-01

    instigating the organisation of two preparatory seminars in 2011 and 2012. The implementation of chapter 4 of the Action Plan is thus up and running. The postponement of the Helsinki Conference will not concretely undermine the upcoming second PrepCom, despite the fact that ensuring that this conference goes ahead represents one the key issues facing the current review cycle. The examination of issues related to non-respect of NPT provisions and the abuse of the right to withdraw from the Treaty, incommensurate with the setback outline above, has in reality become the major challenge of the five-year cycle. Should the State Parties to the NPT fail to seriously deal with the conventional implications of the two proliferation crises ongoing since the turn of the century (namely Iran and North Korea), they would risk once again accentuating the hiatus between a multilateral diplomatic reality and the regional security consequences that comprise its ultimate goal. Let us not forget that the argument that states that the NPT Review Cycle is not the framework in which to examine regional issues does not hold water: firstly, the examination of the goal of a Middle East WMDFZ demonstrates precisely the opposite; next, it is not the Iranian and North Korean cases in of themselves that should be addressed in the NPT forum - it is clear that the search for a resolution of these two crises should continue along parallel diplomatic paths -, but instead their effects on the global nuclear nonproliferation norm. Finally, it is very much the authority of the NPT as an instrument and a guarantee of international security that is the key stake facing the upcoming PrepCom. This should have been the case in New York in 2010 and was not sufficiently so. (author)

  15. Field primatology of today: current ethical issues.

    Science.gov (United States)

    MacKinnon, K C; Riley, E P

    2010-09-01

    As members of professional organizations such as American Society of Primatologists (ASP) and the International Primatological Society (IPS), primatologists must adhere to a set of nonhuman primate-focused principles outlined in resolutions and policy statements on, for example, the ethical treatment of nonhuman primates. Those of us that work in the field must also address issues such as the protection of primate health in the wild and the conservation of wild primate populations. Moreover, we increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navigating the Ethical Landscape, held at the 32nd Annual Meeting of the American Society of Primatologists (ASP) in September 2009. The goals of that symposium and these resulting commentary pieces are threefold: (1) to revive a discussion of key contemporary ethical issues faced by field primatologists, (2) to highlight the need for centrally placed ethical considerations in various facets of our professional lives, particularly research and teaching, and (3) to consider what a comprehensive ethical code that addresses all of these issues might look like.

  16. Physics issues of high bootstrap current tokamaks

    Ozeki, T.; Azumi, M.; Ishii, Y.

    1997-01-01

    Physics issues of a tokamak plasma with a hollow current profile produced by a large bootstrap current are discussed based on experiments in JT-60U. An internal transport barrier for both ions and electrons was obtained just inside the radius of zero magnetic shear in JT-60U. Analysis of the toroidal ITG microinstability by toroidal particle simulation shows that weak and negative shear reduces the toroidal coupling and suppresses the ITG mode. A hard beta limit was observed in JT-60U negative shear experiments. Ideal MHD mode analysis shows that the n = 1 pressure-driven kink mode is a plausible candidate. One of the methods to improve the beta limit against the kink mode is to widen the negative shear region, which can induce a broader pressure profile resulting in a higher beta limit. The TAE mode for the hollow current profile is less unstable than that for the monotonic current profile. The reason is that the continuum gaps near the zero shear region are not aligned when the radius of q min is close to the region of high ∇n e . Finally, a method for stable start-up for a plasma with a hollow current profile is describe, and stable sustainment of a steady-state plasma with high bootstrap current is discussed. (Author)

    Full Text Available During the adolescent period, they experience rapid physical, emotional, cognitive developments while they establish their lifestyle and habitual routines that strongly influence adult health and life. Recent rapid economic growth in Korea, and the earlier onset of physical, sexual, and psychological maturation of adolescents, has resulted in changes in the health status of adolescents from many years ago. Risk-taking behaviors such as drinking alcohol, smoking, and sexual experiences are critical issues that affect the health of, adolescents. Therefore, it is important for pediatricians to note the that risk-taking behaviors of adolescents in Korea that are caused by individual psychosocial factors. This review article illustrates the current health status of Korean adolescents and provides an overview of risktaking behaviors, to inform pediatricians about some of the key issues.

    The assessment of radiation risk needs to be seen against the background of a historical development that has reversed the initial belief in a general beneficial effect of radiation to apprehension and fear. Numerical risk estimates are, today, based on large epidemiological studies, and the observations on the A-bomb survivors are outlined as the primary source of information. Since the epidemiological findings are obtained from relatively high radiation exposures, extrapolations are required to the much lower doses that are relevant to radiation protection. The evolution of extrapolation procedures up to current attempts at mechanistic modelling is outlined, and some of the open issues are reviewed. (author)

  20. Analytical difficulties facing today's regulatory laboratories: issues in method validation.

    Science.gov (United States)

    MacNeil, James D

    2012-08-01

    The challenges facing analytical laboratories today are not unlike those faced in the past, although both the degree of complexity and the rate of change have increased. Challenges such as development and maintenance of expertise, maintenance and up-dating of equipment, and the introduction of new test methods have always been familiar themes for analytical laboratories, but international guidelines for laboratories involved in the import and export testing of food require management of such changes in a context which includes quality assurance, accreditation, and method validation considerations. Decisions as to when a change in a method requires re-validation of the method or on the design of a validation scheme for a complex multi-residue method require a well-considered strategy, based on a current knowledge of international guidance documents and regulatory requirements, as well the laboratory's quality system requirements. Validation demonstrates that a method is 'fit for purpose', so the requirement for validation should be assessed in terms of the intended use of a method and, in the case of change or modification of a method, whether that change or modification may affect a previously validated performance characteristic. In general, method validation involves method scope, calibration-related parameters, method precision, and recovery. Any method change which may affect method scope or any performance parameters will require re-validation. Some typical situations involving change in methods are discussed and a decision process proposed for selection of appropriate validation measures. © 2012 John Wiley & Sons, Ltd.

  1. Reforming health care in Canada: current issues

    Directory of Open Access Journals (Sweden)

    Baris Enis

    1998-01-01

    Full Text Available This paper examines the current health care reform issues in Canada. The provincial health insurance plans of the 1960s and 1970s had the untoward effects of limiting the federal government's clout for cost control and of promoting a system centered on inpatient and medical care. Recently, several provincial commissions reported that the current governance structures and management processes are outmoded in light of new knowledge, new fiscal realities and the evolution of power among stake-holders. They recommend decentralized governance and restructuring for better management and more citizen participation. Although Canada's health care system remains committed to safeguarding its guiding principles, the balance of power may be shifting from providers to citizens and "technocrats". Also, all provinces are likely to increase their pressure on physicians by means of salary caps, by exploring payment methods such as capitation, limiting access to costly technology, and by demanding practice changes based on evidence of cost-effectiveness.

  2. Current issues and strategies for transmission planning

    2008-07-01

    Following the widespread deregulation of the electric power industry in the early 1990s, significant changes occurred in the regulatory and planning environments of the industry. Several regions of North America remain fully or partially regulated in the traditional sense including most Canadian provinces, except for Alberta and Ontario. Although the Mexican system has separate generation and transmission companies and current restructuring efforts are underway, all companies are state-owned, and private investment in energy is heavily constrained by the Mexican constitution. In these regulated regions, traditional generation and transmission expansion planning methods remain in use. This paper presented an overview of current trends in transmission planning strategies that have evolved in response to the restructuring of the power industry, and a conceptual framework of a procedure that would guide planners faced with the challenges of incorporating large scale wind generation in deregulated environments. The paper provided background information on the effect of deregulation on transmission planning. Planning strategies that were discussed included quantifying risk to help identify best alternatives; use of reference systems to estimate generator costs and reduce uncertainty; project based transmission expansion; transmission construction ahead of generation; and generation ahead of transmission. The impact of wind on transmission planning as well as future work addressing challenges posed by wind were also addressed. Research is continuing in this area to illustrate the concepts proposed through a detailed case study. 15 refs., 2 figs.

  3. Urban science education: examining current issues through a historical lens

    2014-12-01

    This paper reviews and synthesizes urban science education studies published between 2000 and 2013 with a view to identifying current challenges faced by both teachers and students in urban classrooms. Additionally, this paper considers the historical events that have shaped the conditions, bureaucracies, and interactions of urban institutions. When the findings from these urban science education studies were consolidated with the historical overview provided, it was revealed that the basic design and regulatory policies of urban schools have not substantively changed since their establishment in the nineteenth century. Teachers in urban science classrooms continue to face issues of inequality, poverty, and social injustice as they struggle to meet the needs of an increasingly diverse student population. Furthermore, persistent concerns of conflicting Discourses, cultural dissonance, and oppression create formidable barriers to science learning. Despite the many modifications in structure and organization, urban students are still subjugated and marginalized in systems that emphasize control and order over high-quality science education.

    Canadian training in the clinical neurosciences, neurology and neurosurgery, faces significant challenges. New balances are being set by residents, their associations and the Royal College of Physicians and Surgeons of Canada between clinical service, education and personal time. The nature of hospital-provided medical service has changed significantly over the past decade, impacting importantly on resident training. Finally, future manpower needs are of concern, especially in the field of neurosurgery, where it appears that soon more specialists will be trained than can be absorbed into the Canadian health care system. A special symposium on current challenges in clinical neuroscience training was held at the Canadian Congress of Neurological Sciences in June 2000. Representatives from the Canadian Association of Interns and Residents, the Royal College of Physicians and Surgeons of Canada and English and French neurology and neurosurgery training programs made presentations, which are summarized in this report. Residency training has become less service-oriented, and this trend will continue. In order to manage the increasingly sophisticated hospital services of neurology and neurosurgery, resident-alternatives in the form of physician "moonlighters" or more permanent hospital-based clinicians or "hospitalists" will be necessary in order to operate major neuroclinical units. Health authorities and hospitals will need to recognize and assume this responsibility. As clinical experience diminishes during residency training, inevitably so will the concept of the fully competent "generalist" at the end of specialty training. Additional subspecialty training is being increasingly sought by graduates, particularly in neurosurgery. Training in neurology and neurosurgery, as in all medical specialties, has changed significantly in recent years and continues to change. Programs and hospitals need to adapt to these changes in order to ensure the production of fully

    Transplantation of allogenic pancreatic islets is a minimally invasive treatment option to control severe hypoglycemia and dependence on exogenous insulin among type 1 diabetes (T1D) patients. This overview summarizes the current issues and progress in islet transplantation outcomes and research. Several clinical trials from North America and other countries have documented the safety and efficacy of clinical islet transplantation for T1D patients with impaired hypoglycemia awareness. A recently completed phase 3 clinical trial allows centres in the United States to apply for a Food and Drug Administration Biologics License for the procedure. Introduction of anti-inflammatory drugs along with T-cell depleting induction therapy has significantly improved long-term function of transplanted islets. Research into islet biomarkers, immunosuppression, extrahepatic transplant sites and potential alternative beta cell sources is driving further progress. Allogeneic islet transplantation has vastly improved over the past two decades. Success in restoration of glycemic control and hypoglycemic awareness after islet transplantation has been further highlighted by clinical trials. However, lack of effective strategies to maintain long-term islet function and insufficient sources of donor tissue still impose limitations to the widespread use of islet transplantation. In the United States, wide adoption of this technology still awaits regulatory approval and, importantly, a financial mechanism to support the use of this technology.

    Full Text Available South African managers today find themselves squeezed between juxtapositions, such as international competition and simultaneous skill development programmes to combat illiteracy. A second example is high unemployment and the concurrent shortage of IT specialists. Affirmative action has led to troublesome labour relations. HIV/AIDS has an enormous impact on business and must be managed. South African managers need to change their managerial approaches to cope with the increasing demands of this country. Managers must be aware of the realities facing them and know how to turn them into potential growth opportunities for their organisations and South Africa as a country.

    Giusti, C.

    2002-01-01

    The role of correlations and two-body currents in one-nucleon emission reactions induced by an electromagnetic probe is discussed. The theoretical framework for cross section calculations is outlined and some results are presented for the exclusive "1"6O(e,e'p) "1"5N and "1"6O(γ, p) "1"5N reactions in relativistic and nonrelativistic models. A reliable and consistent evaluation of different types of correlations is needed to determine the spectroscopic factors. A consistent description of (e,e'p) and (γ, p) data, with the same spectroscopic factors, can be obtained when meson-exchange currents (MEC) are included in the theoretical model. MEC give an important contribution to (γ, p) cross sections and have only a small effect in (e, e'p). In the relativistic model the two-body seagull current affects the calculated cross sections less than in the nonrelativistic calculations.

  16. Current technical issues in international safeguards

    Bennett, C.A.

    1977-01-01

    Safeguards systems, and the associated need for technical and systems development, reflect changing conditions and concerns associated with the nuclear fuel cycle and the safety and security of nuclear materials and facilities. In particular, the implementation of international safeguards has led to the recognition of certain technical issues, both old and new, which are in need of resolution. These are: 1. The grading of nuclear materials and facilities with respect to their relative safeguards significance. 2. The extension and upgrading of safeguards techniques to maintain adequate protection in view of constantly increasing amounts of material to be safeguarded. 3. The balance between safeguards mechanisms based on physical protection and material accounting, and the role of surveillance and containment in each case. 4. The role of information systems as a basis for both analytical feedback and the determination of the factors affecting system effectiveness and their interrelationship. 5. A determination of the degree to which the overall technical effectiveness of international inspection activities can be quantified. Each of these technical issues must be considered in light of the specific objectives of international safeguards, which differ from domestic safeguards in terms of the level of the threat, the safeguards mechanisms available, and the diversion strategies assumed. Their resolution in this international context is essential if the effectiveness and viability of international safeguards are to be maintained

  20. Reproductive rights: Current issues of late abortion

    Directory of Open Access Journals (Sweden)

    Mujović-Zornić Hajrija

    2009-01-01

    Full Text Available This article considers the legal issues surrounding induced late abortion in cases when severe medical, therapeutic or ethical reasons have not been in dispute. Generally discussing the essential question about abortion today, it means not anymore legality of abortion but, in the first place, safety of abortion. From the aspect of woman health the most important aim is to detect and avoid possible risks of medical intervention, such as late abortion present. This is the matter of medical law context and also the matter of the woman's reproductive rights, here observed through legislation and court practice. The gynecologist has an obligation to obtain the informed consent of each patient. Information's should be presented in reasonably understandable terms and include alternative modes of treatment, objectives, risks, benefits, possible complications, and anticipated results of such treatment. Pregnant woman should receive supportive counseling before and particularly after the procedure. The method chosen for all terminations should ensure that the fetus is born dead. This should be undertaken by an appropriately trained practitioner. Reform in abortion law, making it legally accessible to woman, is not necessarily the product of a belief in woman's rights, but can be a means of bringing the practice of abortion back under better control. Counseling and good medical practice in performing late abortion are the instruments to drive this point even further home. It does not undermine the woman who wants to make a positive decision about her life and its purpose is not to produce feelings of insecurity and guilt. It concludes that existing law should not be changed but that clear rules should be devised and board created to review late term abortion. In Serbia, this leads to creation and set up guidelines for reconciling medical justification for late abortion with existing law, especially with solutions which brings comparative law. .

    Full Text Available This introduction to the special issue entitled Me-diated Inter-faces begins by bringing into question the concept of positioning: what is it that we are doing when we take a position within the study of social media? Reviewing the work of the inaugural manifestos of the journal Social Media + Society on one hand, and the introduction to the special issue on selfies for the International Journal of Communications on the other, this introduction provides both critical and creative in-roads for thinking and re-thinking digital self-images shared on social media. Given the constantly changing nature of social media, this paper is a call to researchers of social media to not fall prey to the ossification of our current positions since theorizing the “social” in social media means always at once theorizing the body. As such this intro offers numerous and diverse perspectives on the body that might inform emerging thoughts on the socially media body. The introduction then provides an overview of the papers in this special issue and concludes by offering openings and ruptures for further discussion, rather than closure of conclusions.

    Science.gov (United States)

    Davis, Sheila P; Davis, Danyetta D

    2010-01-01

    Current trends in higher education in the United States demand that nursing take stock of how it is prepared or being prepared to face challenges and issues impacting on its future. The intense effort made to attract students to pursue advanced training in science and engineering in the United States pales in comparison to the numbers of science and engineering majors produced yearly in international schools. As a result, more and more jobs are being outsourced to international markets. Could international outsourcing become a method of nursing education? Authors submit that to remain competitive, the nursing profession must attract a younger cohort of technologically savvy students and faculty reflective of the growing diverse population in the United States. Additionally, nursing programs in research universities face even more daunting challenges as it relates to mandates for funded research programs of educational units. This article offers suggestions and recommendations for nursing programs in higher education institutions on ways to attract and retain ethnic minorities and of how to harness the power of research to address burgeoning societal health challenges.

    Lemieux-Charles, L; Meslin, E M; Aird, C; Baker, R; Leatt, P

    1993-01-01

    This article explores the ethical issues faced by clinicians with management responsibilities (clinician/managers) when making decisions related to resource allocation and utilization at a Canadian teaching hospital. Using a focus group method, 28 individuals participated in four homogeneous groups that included nurse managers, managers from other professional groups, and physician managers. Ethical issues that recurred throughout the discussions included fairness, concern with preventing harm, consumer/patient choice, balancing needs of different groups of patients, conflict between financial incentives and patient needs, and professional autonomy. The particular issue of conflict is analyzed from two perspectives--a theory of professional-bureaucratic roles and of obligation--that illustrate how both management and philosophical issues are related. The findings suggest that decentralizing resource allocation and utilization decisions does raise ethical issues for clinician/managers and that a better understanding of these issues can be obtained using an interdisciplinary perspective.

    The Internet search engines, which have powerful search/sort functions and ease of use features, have become an indispensable tool for many individuals. The current study is to test whether the short-term Internet search training can make people more dependent on it. Thirty-one subjects out of forty subjects completed the search training study which included a pre-test, a six-day's training of Internet search, and a post-test. During the pre- and post- tests, subjects were asked to search online the answers to 40 unusual questions, remember the answers and recall them in the scanner. Un-learned questions were randomly presented at the recalling stage in order to elicited search impulse. Comparing to the pre-test, subjects in the post-test reported higher impulse to use search engines to answer un-learned questions. Consistently, subjects showed higher brain activations in dorsolateral prefrontal cortex and anterior cingulate cortex in the post-test than in the pre-test. In addition, there were significant positive correlations self-reported search impulse and brain responses in the frontal areas. The results suggest that a simple six-day's Internet search training can make people dependent on the search tools when facing unknown issues. People are easily dependent on the Internet search engines.

    In Southeast Asia, hundreds of thousands of young rural women migrate from their villages to the larger cities in search of work. Many find employment with beer companies or in the clubs where beer is sold, promoting the sale of beer. Previous research suggests these young migrants are in a highly vulnerable position. This paper will describe the findings of an October 2009 meeting to develop a research agenda on the sexual and reproductive health of beer promoters and a subsequent pilot study of focus groups with beer promoters to review this agenda. Participants of the research meeting representing beer promoters, academics, non-governmental organizations (NGOs), government and the beer industry from Cambodia, Thailand, Laos, and Vietnam collaborated in the development of three key research themes. The themes were verified in focus group discussions with beer promoters organized by local research partners in all four countries. The focus group participants were asked what they felt were the key sexual and reproductive health issues facing them in a non-directive and unstructured manner, and then asked to comment more specifically on the research priorities developed at the meeting. The focus groups were recorded digitally, transcribed, and translated into English. The data were analyzed by coding for common themes and then developing matrices to compare themes between groups. The participants of the meeting identified three key research themes: occupational health (including harassment and violence, working conditions, and fair pay), gender and social norms (focusing on the impact of power relations between the genders on women's health), and reproductive health (knowledge and access to reproductive health care services). The participants in the focus groups in all four countries agreed that these were key priorities for them, though the emphasis on the most important issues varied between groups of women.

    Full Text Available This mixed method study sought to explore the issues that faced secondary teachers in a rural central Georgia public high school when attempting to implement a multicultural education program.  The key issues of this study centered on the teachers’ multicultural education training and the school’s multicultural education program. Data were gathered from a total of thirty randomly chosen teachers in the Social Studies, Math and English departments at the school. Twenty-five of the thirty teachers received a hard copy four question Likert scale survey to complete. The remaining 5 participants took part in face-to-face interviews discussing six open-ended questions.  The findings pointed to several issues facing the teachers such as the lack of an officially implemented multicultural education program, the lack of support from school administrators, no in-service training available for teachers, parental and student misapprehension, and a lack of an officially defined policy on implementation and support of a multicultural education program from administrators locally and district-wide.

Through the analysis of visual SnapChat messages we investigate how SnapChat requires the sender to put an ‘ugly’ face...... already secured their popular status on the heterosexual marketplace in the broad context of the school. Thus SnapChat functions both as a challenge to beauty norms of ‘flawless faces’ and as a reinscription of these same norms by further manifesting the exclusive status of the popular girl...

  5. Looking for myself: current multisensory input alters self-face recognition.

    2008-01-01

    How do I know the person I see in the mirror is really me? Is it because I know the person simply looks like me, or is it because the mirror reflection moves when I move, and I see it being touched when I feel touch myself? Studies of face-recognition suggest that visual recognition of stored visual features inform self-face recognition. In contrast, body-recognition studies conclude that multisensory integration is the main cue to selfhood. The present study investigates for the first time the specific contribution of current multisensory input for self-face recognition. Participants were stroked on their face while they were looking at a morphed face being touched in synchrony or asynchrony. Before and after the visuo-tactile stimulation participants performed a self-recognition task. The results show that multisensory signals have a significant effect on self-face recognition. Synchronous tactile stimulation while watching another person's face being similarly touched produced a bias in recognizing one's own face, in the direction of the other person included in the representation of one's own face. Multisensory integration can update cognitive representations of one's body, such as the sense of ownership. The present study extends this converging evidence by showing that the correlation of synchronous multisensory signals also updates the representation of one's face. The face is a key feature of our identity, but at the same time is a source of rich multisensory experiences used to maintain or update self-representations.

  6. Environmental economics and policy making in developing countries. Current issues

    2001-01-01

    In developing countries, where growth expectations are high, least-cost environmental policies are crucial since they can reduce the conflict between economic growth and the environment. In view of this, policymakers in these economies must be very aware of the relationship between economic and environmental issues to offer policy initiatives which can increase efficiency and improve equity. The authors provide a comprehensive analysis of topics varying from the general problems of growth and conservation to specific applications such as; pollution costs, environmental taxation, deforestation and climate change. This volume also offers policymakers a comprehensive view of the challenges they face, and the legacies they leave, in order to convert environmental policy making into an actual programme of welfare improvement.

    The first use of nuclear power for the generation of electricity on a commercial scale occurred in the United Kingdom in 1956. Today, 13 OECD countries have 318 nuclear units in operation and 66 more in construction or on order. This outstanding achievement is the result of the successful organization, start up, and operation of an industry to design, build, equip, fuel, and maintain these facilites. Nuclear power, however, is currently troubled by a number of issues that may impair its ability to reach its full potential. The industry has acknowledged problems that can be and are being managed. But the industry also has a number of political difficulties that could be beyond its ability to resolve with its own resources. These are issues common to the introduction of new technologies into a complex world. Nevertheless, nuclear power continues to be the means by which we can provide the electric power needed to raise the living standard of everyone on the globe

    Female sex trafficking is a pressing concern. In this article, we provide a comprehensive overview of relevant issues regarding the concept of female sex trafficking and research in the field of human trafficking, drawing on a variety of disciplines, including economics, gender and sexuality studies, psychology, sociology, law, and social work. We discuss the debates surrounding the definition of human trafficking, compare and contrast it with human smuggling, and outline connections between female sex trafficking and the issue of sex work and prostitution. We further discuss the history and current estimations of female sex trafficking. We then outline the main actors in female sex trafficking, including trafficked persons, traffickers, clients, and service providers, and we overview the trafficking process from recruitment to identification, recovery, and (re)integration. Finally, we conclude with recommendations for future research that tie together the concepts of vulnerability, exploitation, and long-term recovery and (re)integration.

    1989-01-01

    Despite the fact that the profession of nurse-midwifery and feminism are both disciplines concerned with women and issues affecting women's lives, there has been little investigation or acknowledgement of relationships between their two paradigms. The work presented here is an attempt to discover both similarities and differences between nurse-midwifery and feminist thought. Using a historical approach, it is shown that despite the common goal of improving and maintaining women's status in the world, whether in general or more specifically with regard to health, feminist theorists and nurse-midwives, to a large degree, have worked separately from each other, rarely acknowledging in any formal way the importance of the other discipline. Current issues that have an effect on the practice of nurse-midwifery today--lay midwifery, the profession of nursing, and nurse-midwifery research--are presented in relation to contemporary feminist thought.

    Cloud computing is poised to become one of the most important and fundamental shifts in how computing is consumed and used. Forecasts show that government will play a lead role in adopting cloud computing - for data storage, applications, and processing power, as IT executives seek to maximize their returns on limited procurement budgets in these challenging economic times. After an overview of the cloud computing concept, this article explores the security issues facing public sector use of cloud computing and looks to the risk and benefits of shifting to cloud-based models. It concludes with an analysis of the challenges that lie ahead for government use of cloud resources.

    National health care expenditures are rising rapidly, bringing on a health care financing crisis. For this reason, it is useful to see how hospitals are facing the price issues of the 1990's. This study examines the price strategies hospitals follow and analyzes their observations on price sensitivity and payer mix. The results clearly show that hospitals have not given much attention to the pricing variable. The study suggests that marketing and finance will have to work closely together in developing future pricing strategies.

Twenty-five women in their second to fifth week of treatment were given the survey to determine these issues. Responses were then grouped by age category and results compiled. Regardless of age, a majority of women felt that they and their spouses had become closer since their diagnosis and described their spouses as being supportive. Scheduling appointment times around childcare was important for some women. Almost half of the women experienced a change in employment status as a result of their diagnosis. Appointment times and work schedules were important for some women still working. In all age groups, women experienced fatigue at least sometimes. (author)

    On the Cutting Edge, a comprehensive, discipline-wide professional development program for current and future geoscience faculty, aims to develop a geoscience professoriate committed to high-quality instruction based on currency in scientific knowledge, good pedagogic practice, and research on learning. Our program provides an integrated workshop series and online teaching resources. Since 2002, we have offered more than 80 face-to-face workshops, virtual workshops and webinars, and hybrid events. Participants come from two-year colleges and four-year colleges and universities. The workshop series is designed to address the needs of faculty in all career stages at the full spectrum of institutions and covering the breadth of the geoscience curriculum. We select timely and compelling topics and create opportunities of interest to faculty. We offer workshops on course design, new geoscience research and pedagogical topics, core geoscience curriculum topics, and introductory courses as well as workshops for early career faculty and for future faculty. Our workshops are designed to model good teaching practice. We set workshop goals that guide workshop planning and evaluation. Workshops are interactive, emphasize participant learning, provide opportunities for participants to interact and share experience/knowledge, provide good resources, give participants time to reflect and to develop action plans, and help transform their ideas about teaching. We emphasize the importance of adaptation in the context of their specific situations. For virtual workshops and webinars we use icebreakers and other structured interactions to build a comfortable workshop community; promote interaction through features on webinar software, chat-aided question and answer, small-group synchronous interactions, and/or discussion boards; plan detailed schedules for workshop events; use asynchronous discussions and recordings of synchronous events given that participants are busy with their

    Myers, L.C.

    1994-04-01

    Human beings utilize energy in many forms and from a variety of sources. A number of countries have chosen nuclear-electric generation as a component of their energy system. At the end of 1992, there were 419 power reactors operating in 29 countries, accounting for more than 15% of the world's production of electricity. In 1992, 13 countries derived at least 25% of their electricity from nuclear units, with Lithuania leading at just over 78%, followed closely by France at 72%. In the same year, Canada produced about 16% of its electricity from nuclear units. Some 53 power reactors are under construction in 14 countries outside the former USSR. Within the ex-USSR countries, six new reactors are currently under construction. No human endeavour carries the guarantee of perfect safety and the question of whether of not nuclear-electric generation represents an 'acceptable' risk to society has long been vigorously debated. Until the events of late April 1986 in the then Soviet Union, nuclear safety had indeed been an issue for discussion, for some concern, but not for alarm. The accident at the Chernobyl reactor irrevocably changed all that. This disaster brought the matter of nuclear safety into the public mind in a dramatic fashion. Subsequent opening of the ex-Soviet nuclear power program to outside scrutiny has done little to calm people's concerns about the safety of nuclear power in that part of the world. This paper discusses the issue of safety in complex energy systems and provides brief accounts of some of the most serious reactor accidents that have occurred to date, as well as more recent, less dramatic events touching on the safety issue.

    2015-12-01

    In this review, current issues and opportunities in food safety assessment are discussed. Food safety is considered an essential element inherent in global food security. Hazard characterization is pivotal within the continuum of risk assessment, but it may be conceived only within a very limited frame as a true alternative to risk assessment. Elucidation of the mode of action underlying a given hazard is vital to create a plausible basis for human toxicology evaluation. Risk assessment, to convey meaningful risk communication, must be based on appropriate and reliable consideration of both exposure and mode of action. New perspectives, provided by monitoring human exogenous and endogenous exposure biomarkers, are considered of great promise to support classical risk extrapolation from animal toxicology. © The Author(s) 2015.

    2000-01-01

    The Agency has included activities on research reactor safety in its Programme and Budget (P and B) since its inception in 1957. Since then, these activities have traditionally been oriented to fulfil the Agency's functions and obligations. At the end of the decade of the eighties, the Agency's Research Reactor Safety Programme (RRSP) consisted of a limited number of tasks related to the preparation of safety related publications and the conduct of safety missions to research reactor facilities. It was at the beginning of the nineties when the RRSP was upgraded and expanded as a subprogramme of the Agency's P and B. This subprogramme continued including activities related to the above subjects and started addressing an increasing number of issues related to the current situation of research reactors (in operation and shut down) around the world such as reactor ageing, modifications and decommissioning. The present paper discusses some of the above issues as recognised by various external review or advisory groups (e.g., Peer Review Groups under the Agency's Performance Programme Appraisal System (PPAS) or the standing International Nuclear Safety Advisory Group (INSAG)) and the impact of their recommendations on the preparation and implementation of the part of the Agency's P and B relating to the above subject.

    2013-03-01

    This review considers psychosocial oncofertility research relevant to adolescents and young adults over their lifetime. There is growing awareness of the fertility preservation needs of younger males including lowering practical barriers and attending to emotional impact. Despite decisional challenges facing females--the experimental nature of procedures, time involved and potential involvement of partners/donors (for embryo cryopreservation)--findings suggest they too benefit from fertility information at diagnosis and access to fertility specialists. Studies consistently report that fertility concerns affect well-being, relationships and life planning. Both genders thus want fertility issues to be raised proactively by professionals in the years following diagnosis: to help them make informed decisions at a time relevant to them, develop coping strategies for current and future related areas and to be referred to specialist and/or therapeutic help if needed. Little is known about why cancer survivors are less likely to marry or have children, or about their parenthood experiences.

    Full Text Available Sunil Sethi, Kamran Zaman, Neha Jain Department of Medical Microbiology, Postgraduate Institute of Medical Education and Research, Chandigarh, India Abstract: Mycoplasma genitalium is one of the important causes of non-gonococcal urethritis. Rising incidence and emerging antimicrobial resistance are a major concern these days. The poor clinical outcomes with doxycycline therapy led to the use of azithromycin as the primary drug of choice. Single-dose azithromycin regimen over a period of time was changed to extended regimen following studies showing better clinical cures and less risk of resistance development. However, emerging macrolide resistance, either due to transmission of resistance or drug pressure has further worsened the management of this infection. The issues of drug resistance and treatment failures also exist in cases of M. genitalium infection. At present, the emergence of multidrug-resistant (MDR M. genitalium strains is an alarming sign for its treatment and the associated public health impact due to its complications. However, newer drugs like pristinamycin, solithromycin, sitafloxacin, and others have shown a hope for the clinical cure, but need further clinical trials to optimize the therapeutic dosing schedules and formulate appropriate treatment regimens. Rampant and inappropriate use of these newer drugs will further sabotage future attempts to manage MDR strains. There is currently a need to formulate diagnostic algorithms and etiology-based treatment regimens rather than the syndromic approach, preferably using combination therapy instead of a monotherapy. Awareness about the current guidelines and recommended treatment regimens among clinicians and local practitioners is of utmost importance. Antimicrobial resistance testing and global surveillance are required to assess the efficacy of current treatment regimens and for guiding future research for the early detection and management of MDR M. genitalium infections

  1. Exploring morally relevant issues facing families in their decisions to monitor the health-related behaviours of loved ones.

    Gammon, D; Christiansen, E K; Wynn, R

    2009-07-01

    Patient self-management of disease is increasingly supported by technologies that can monitor a wide range of behavioural and biomedical parameters. Incorporated into everyday devices such as cell phones and clothes, these technologies become integral to the psychosocial aspects of everyday life. Many technologies are likely to be marketed directly to families with ill members, and families may enlist the support of clinicians in shaping use. Current ethical frameworks are mainly conceptualised from the perspective of caregivers, researchers, developers and regulators in order to ensure the ethics of their own practices. This paper focuses on families as autonomous decision-makers outside the regulated context of healthcare. We discuss some morally relevant issues facing families in their decisions to monitor the health-related behaviours of loved ones. An example - remote parental monitoring of adolescent blood glucose - is presented and discussed through the lens of two contrasting accounts of ethics; one reflecting the predominant focus on health outcomes within the health technology assessment (HTA) framework and the other that attends to the broader sociocultural contexts shaping technologies and their implications. Issues discussed include the focus of assessments, informed consent and child assent, and family co-creation of system characteristics and implications. The parents' decisions to remotely monitor their child has relational implications that are likely to influence conflict levels and thus also health outcomes. Current efforts to better integrate outcome assessments with social and ethical assessments are particularly relevant for informed decision-making about health monitoring technologies in families.

  2. The Janus-Faced Role of Gambling Flow in Addiction Issues.

    Trivedi, Rohit H; Teichert, Thorsten

    2017-03-01

    Flow experience has been widely investigated in experiential activities such as sports, the performing arts, gaming, and Internet usage. Most studies focus on the positive aspects of flow experience and its effect on performance. In stark contrast, gambling research focusing on the negative side of addiction lacks an in-depth investigation of gamblers' (positive) flow encounters. This separation of research lines seems out of place given that recent research indicates connections between flow and addiction. Joining both constructs in a causal-effects model helps one gain a better understanding of their relationship and its contingencies. This article empirically investigates whether and how it is possible to observe a "Janus face" of flow with its various sub-dimensions in online gambling. Empirical data were collected from 500 online gamblers by applying a structured questionnaire with established scales. The data were analyzed with a confirmatory factor analysis and a double-hurdle model to separate casual gamblers who are unsusceptible to any addiction issues from gamblers affected by initiatory addiction issues. The findings indicate that online gambling addiction is negatively influenced by two sub-dimensions of flow experience, namely a sense of control and concentration on the task at hand, whereas it is enhanced by a transformation of time and autotelic experience.

    Cell culture technology has spread prolifically within a century, a variety of culture media has been designed. This review goes through the history, characteristics and current issues of animal-cell culture media. A literature search was performed on PubMed and Google Scholar between 1880 and May 2016 using appropriate keywords. At the dawn of cell culture technology, the major components of media were naturally derived products such as serum. The field then gradually shifted to the use of chemical-based synthetic media because naturally derived ingredients have their disadvantages such as large batch-to-batch variation. Today, industrially important cells can be cultured in synthetic media. Nevertheless, the combinations and concentrations of the components in these media remain to be optimized. In addition, serum-containing media are still in general use in the field of basic research. In the fields of assisted reproductive technologies and regenerative medicine, some of the medium components are naturally derived in nearly all instances. Further improvements of culture media are desirable, which will certainly contribute to a reduction in the experimental variation, enhance productivity among biopharmaceuticals, improve treatment outcomes of assisted reproductive technologies, and facilitate implementation and popularization of regenerative medicine.

    Full Text Available Among the processes cosmopolitan societies undergo at the present moment, is the unprecedented increase in mass migration across cultures. What challenges are faced by both immigrants, who have to settle in novel socio-cultural environments, and by the host populations accepting them? The current qualitative study investigates the nature of identity construction among Russian-speaking immigrants in New Zealand, applying thematic analysis for the interpretation of the data collected via 23 in-depth interviews. Among the most common themes articulated by the participants was the feeling of identity loss. A taken-for-granted sense of identity, brought by the participants from their culture of origin, was not validated by their new society of residence, mostly due to the lack of appropriate cultural resources. The participants were faced with a challenge of re-constructing their old identity, or constructing a new one, utilising the available resources in the community around them. At the same time, there was a sub-group for whom this challenge brought the realisation that the nature of their identity is cosmopolitan, rather than located within any particular culture or geographical space.

    With the advent of flexible electronics, lithium-ion batteries have become a key component of high performance energy storage systems. Thus, considerable effort is made to keep up with the development of flexible lithium-ion batteries. To date, many researchers have studied newly designed batteries with flexibility, however, there are several significant challenges that need to be overcome, such as degradation of electrodes under external load, poor battery performance, and complicated cell preparation procedures. In addition, an in-depth understanding of the current challenges for flexible batteries is rarely addressed in a systematical and practical way. Herein, recent progress and current issues of flexible lithium-ion batteries in terms of battery materials and cell designs are reviewed. A critical overview of important issues and challenges for the practical application of flexible lithium-ion batteries is also provided. Finally, the strategies are discussed to overcome current limitations of the practical use of flexible lithium-based batteries, providing a direction for future research. © 2017 WILEY-VCH Verlag GmbH & Co.

    The objective of this research was to tackle several problems that are currently of great importance to NASA. In a liquid rocket engine several complex processes take place that are not thoroughly understood. Droplet evaporation, turbulence, finite rate chemistry, instability, and injection/atomization phenomena are some of the critical issues being encountered in a liquid rocket engine environment. Pulse Detonation Engines (PDE) performance, combustion chamber instability analysis, 60K motor flowfield pattern from hydrocarbon fuel combustion, and 3D flowfield analysis for the Combined Cycle engine were of special interest to NASA. During the summer of 1997, we made an attempt to generate computational results for all of the above problems and shed some light on understanding some of the complex physical phenomena. For this purpose, the Liquid Thrust Chamber Performance (LTCP) code, mainly designed for liquid rocket engine applications, was utilized. The following test cases were considered: (1) Characterization of a detonation wave in a Pulse Detonation Tube; (2) 60K Motor wall temperature studies; (3) Propagation of a pressure pulse in a combustion chamber (under single and two-phase flow conditions); (4) Transonic region flowfield analysis affected by viscous effects; (5) Exploring the viscous differences between a smooth and a corrugated wall; and (6) 3D thrust chamber flowfield analysis of the Combined Cycle engine. It was shown that the LTCP-2D and LTCP-3D codes are capable of solving complex and stiff conservation equations for gaseous and droplet phases in a very robust and efficient manner. These codes can be run on a workstation and personal computers (PC's).

    Major strategic issues facing the global thermoelectric sector include environmental regulation, climate change and increasing electricity demand. We have addressed such issues by modeling thermoelectric generation in the Northeastern United States that is reliant on cooling under five sensitivity tests to evaluate losses/gains in power production, thermal pollution and suitable aquatic habitat, comparing the contemporary baseline (2000-2010) with potential future states. Integral to the analysis, we developed a methodology to quantify river water availability for cooling, which we define as an ecosystem service. Projected climate conditions reduce river water available for efficient power plant operations and the river's capacity to absorb waste heat, causing a loss of regional thermoelectric generation (RTG) (2.5%) in some summers that, compared to the contemporary baseline, is equal to the summertime electricity consumption of 1.3 million Northeastern US homes. Vulnerabilities to warm temperatures and thermal pollution can be alleviated through the use of more efficient natural gas (NG) power plants that have a reduced reliance on cooling water. Conversion of once-through (OT) to cooling tower (CT) systems and the Clean Water Act (CWA) temperature limit regulation, both of which reduce efficiencies at the single plant level, show potential to yield beneficial increases in RTG. This is achieved by obviating the need for large volumes of river water, thereby reducing plant-to-plant interferences through lowering the impact of upstream thermal pollution and preserving a minimum standard of cooling water. The results and methodology framework presented here, which can be extrapolated to other regional assessments with contrasting climates and thermoelectric profiles, can identify opportunities and support decision-making to achieve more efficient energy systems and riverine ecosystem protection.

    2010-05-01

    OBJECTIVES Improving nurses' competence in resolving clinical ethical issues must start with ethics education in training and clinical practice. However, many students complain that they cannot apply classroom learning to actual clinical scenarios. This study explored ethical issues and dilemmas, and their impact experienced by student nurses in clinical practice. METHODS Focus groups were conducted with 44 first-year student nurses from a 2-year college course in northern Taiwan. Interviews were tape-recorded and verbatim transcripts were analysed using content analysis. RESULTS Students expressed and discussed their views in eight focus groups. Analysis of interviews revealed five themes: frustration at inability to help some patients; oppression caused by lower status; lack of honesty and ethical courage; powerlessness, and self-encouragement in adversity. CONCLUSIONS Taiwanese nurse ethics training was only recently introduced and the curriculum has not addressed the clinical reality in Taiwan. This reality includes limitations arising from the medical hierarchy and the socio-cultural role of families in medical decision making, which may inhibit ethical judgements and decision making. In clinical dilemmas, the most common problems faced by Taiwanese nursing students involved not knowing how to handle some situations, inability to abide by principles, and a lack of appropriate role models. Hence, we suggest that nursing ethics education should: (i) integrate scenarios involving ethical dilemmas into daily routines; (ii) give students opportunities to discuss their feelings about their experiences; (iii) allow teachers and students to talk about scenarios with ethical implications, and (iv) provide students with opportunities to reflect on clinical scenarios in order to clarify their values and learn how to respect the value of life.

    To elicit the perceptions of helpline staff who talk to parents of children discharged after cardiac surgery in infancy about parents' key concerns. A qualitative study involving semistructured interviews with 10 staff at four heart charities. Interviews were recorded, transcribed and analysed using Framework analysis. Staff identified the knowledge, communication and support needs of parents which they described in terms of the impact of patient and family factors, sources of support and systems. Staff perceptions of helplines, in terms of the function of a helpline and the roles of its staff, together with staff's personal views based on their experience of multiple encounters with many families, influenced how they viewed families' needs and responded to their requests. Helpline staff provided important, previously uncaptured evidence about the challenges faced by parents of children discharged after cardiac surgery in infancy. Staff have an important role in supporting communication, in terms of speaking to families about how to talk to professionals and talking to professionals directly to get or give information when parents are unable to do so. Capturing the perspective of helpline staff about communication issues has highlighted the need for interventions with professionals as well as parents. ©2018 Foundation Acta Paediatrica.

    The oil industry is particularly concerned with the issue of climate change. The implementation of Greenhouse Gases (GHG) reduction policies can be perceived as an additional environmental constraint for the management of the production chain. It is also represents a first step towards a possible decarbonization of the economy. In the long-term, the fight against global warming calls thus into question the activity level of petroleum companies. Confronted with this, still uncertain, new environmental deal, some petroleum multinationals adopt proactive behaviors, e.g. with voluntary commitments to reduce GHG emissions, or with investments in alternative technologies. First of all, we present the potential economic impacts of the Kyoto Protocol on oil industry. Then, we conduct a comparative analysis of the 'Kyoto risk' for the five largest multinationals of this sector according to their activities and their geographical implantations. Then, for the purpose to interpreting proactive strategies of firms such as BP and Shell, we examine various explanations including 'win-win', public image and the response to broad societal needs. This leads us to formalize the proactive behavior as an anticipatory management of carbon contestability, particularly perceptible in financial markets. Lastly, we try to justify economically investments of companies in the field of alternative energy sources and technologies through the lens of real options theory and by a management of the exhaustible fossil resources.

  3. Fatherhood and parenting as health issues facing the rearrangements of gender.

    Science.gov (United States)

    Ribeiro, Cláudia Regina; Gomes, Romeu; Moreira, Martha Cristina Nunes

    2015-11-01

    In this theoretical essay we aim to discuss paternity as a health issue in the context of contemporary gender roles by considering two lines of argument: (a) paternity, parenting and rearrangements of gender roles; and (b) paternity and parenting as a mutual relationship based on care. In our discussion, we highlight the inclusion of men in the health system from the point of view of paternity. At present this appears to be operating in an instrumental manner, with the mother-infant dyad still a major concern and men not being viewed as individuals with rights to health. Thus, we seek to question the system itself, in relation to its perceptions of the current state of paternity, by taking into consideration recent discussions about gender and sexuality as well as and new family arrangements that may challenge beliefs about the roles of families, fathers and mothers, which have impacts on care. Among other aspects, we conclude that we need to reinvent ourselves because we were not raised under the aegis of diversity and we were also not trained as professionals with a basis in the current problematic divisions that exist between father/mother and sex/gender, among many other previous certainties, all of which does not always help us to promote actions in the area of health.

    Industrial Accident Compensation Insurance (IACI) has a history of about 50 yr, and is the oldest social insurance system in Korea. After more than 20 times of revision improvements in benefits, its contents and claim systems have been upgraded. It became the protector of injured workers and their families, and at the same time became the system which could cope with both financial burden of employers and their responsibilities. However, there are some issues to be reformed to upgrade the IACI: 1) the problems in the approval system of occupational diseases, 2) quality improvement of workers' compensation medical care, 3) vocational rehabilitation and return to work, 4) workers' compensation premiums and out-of-pocket money of injured workers, 5) issues in application of IACI. Growth of IACI cannot be achieved by an effort of an individual. Efforts by workers, owners, and government, in addition to physicians and welfare professionals toward the same goal are required for the next level improvement of IACI.

    Binge drinking (BD), i.e., consuming a large amount of alcohol in a short period of time, is an increasing public health issue. Though no clear definition has been adopted worldwide the speed of drinking seems to be a keystone of this behavior. Developing relevant animal models of BD is a priority for gaining a better characterization of the neurobiological and psychobiological mechanisms underlying this dangerous and harmful behavior. Until recently, preclinical research on BD has been conducted mostly using forced administration of alcohol, but more recent studies used scheduled access to alcohol, to model more voluntary excessive intakes, and to achieve signs of intoxications that mimic the human behavior. The main challenges for future research are discussed regarding the need of good face validity, construct validity and predictive validity of animal models of BD. Copyright © 2018 Elsevier Ltd.

    Salem, Haitham; Nagpal, Caesa; Pigott, Teresa; Teixeira, Antonio Lucio

    2017-01-01

    Background: Akathisia continues to be a significant challenge in current neurological and psychiatric practice. Prompt and accurate detection is often difficult and there is a lack of consensus concerning the neurobiological basis of akathisia. No definitive treatment has been established for akathisia despite numerous preclinical and clinical studies. Method: We reviewed antipsychotic-induced akathisia including its clinical presentation, proposed underlying pathophysiology, current and under investigation therapeutic strategies. Conclusion: Despite the initial promise that second generation antipsychotics would be devoid of akathisia effects, this has not been confirmed. Currently, there are limited therapeutic options for the clinical practice and the evidence supporting the most widely used treatments (beta blockers, anticholinergic drugs) is still absent or inconsistent.

    2006-01-01

    Power sector reforms in India were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden. Investment in the sector was not able to keep pace with growing demand for electricity. This paper takes stock of pre-reform situation in Indian power sector and identifies key concerns that led to initiation of the process of reform. The paper discusses major policy and regulatory changes undertaken since the early 1990s. The paper also illustrates changes in the market structure as we move along the reform process. We also discuss some of the major provisions of the recently enacted Electricity Act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country. In this context, we discuss two issues arising out of it, namely open access and multi-year tariff that we think would have a significant bearing on the performance of the sector in the near future. The paper also evaluates the reform process in the light of some of the regulatory changes undertaken. Finally, the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

    2005-01-01

    Besides pathology endpoints, additional immune function endpoints have been included in the Note for Guidance on Repeated Dose Toxicity by the European Union (July 2001), which concern the analysis of antibody responses to a T-cell-dependent antigen. Guidance papers of other regulatory authorities are published as well. The main issue is the need for functional immunotoxicity testing to detect unintended immunosuppression. The International Conference on Harmonization (ICH) has surveyed studies from the files of the pharmaceutical industry to find the proportion of compounds that can be detected by additional immunotoxicity testing. Preliminary analysis shows that 10-15% of the compounds in the survey only react positively to the additional tests. More data are requested from the pharmaceutical industry. The Expert Working Group of the ICH has decided to choose a cause-for-concern approach to immmunotoxicity rather than a routine-screening approach. The causes for concern are to be defined during ICH negotiations

    Medical photographic image capture and data management has undergone a rapid and compelling change in complexity over the last 20 years. This is because of multiple factors, including significant advances in ease of photograph capture, alongside an evolution of mechanisms of data portability/dissemination, combined with governmental focus on health information privacy. Literature to guide medical, legal, governmental and business professionals when dealing with issues related to medical photography is virtually nonexistent. Herein, we will address the breadth of uses of medical photography, device properties/specific devices utilised for image capture, methods of data transfer and dissemination and patient perceptions and attitudes regarding photography in a medical setting. In addition, we will address the legal implications, including legal precedent, copyright and privacy law, informed consent, protected health information and the Health Insurance Portability and Accountability Act (HIPAA), as they pertain to medical photography. © 2015 John Wiley & Sons Ltd.

    Concluding Comments: Firm government commitment and support - imminent; New financing approaches/models are emerging, repackaging existing methods and combination of project finance/co-operative mode; Global financial crisis will make financing for investors very challenging, especially for large scale infrastructure projects like NNP –financial regulators to impose tougher rules (Basel III, UK bank levy, US Financial Regulatory Bill, etc; Pure project finance is still challenging for nuclear projects - the availability of finance for new NPPs will depend on the initial government support. This presentation presents a “free market” view on investment in nuclear power projects; If the public sector (governments) wishes to invest in nuclear power as part of its socioeconomic development priorities, finance is not a real obstacle; It becomes an issue in the presence of other equally important development needs and private sector participation is sought

    This paper examines the professional and scientific views on the social, ethical and legal issues that impact on the provision of genetic services in Europe. Many aspects have been considered, such as the definition and the aims of genetic services, their organization, the quality assessment, public education, as well as the partnership with patients support groups and the multicultural aspects. The methods was primarily the analysis of professional guidelines, legal frameworks and other documents related to the organization of genetic services, mainly from Europe, but also from USA and international organizations. Then, the method was to examine the background data emerging from an updated report produced by the Concerted Action on Genetic Services in Europe, as well as the issues debated by 43 experts from 17 European countries invited to an international workshop organized by the European Society of Human Genetics Public and Professional Policy Committee in Helsinki, Finland, 8 and 9 September 2000. Some conclusions were identified from the ESHG workshop to arrive at outlines for optimal genetic services. Participants were concerned about equal accessibility and effectiveness of clinical genetic services, quality assessment of services, professional education, multidisciplinarity and division of tasks as well as networking. Within European countries, adherence to the organizational principles of prioritization, regionalization and integration into related health services would maximize equal accessibility and effectiveness of genetic actions. There is a need for harmonization of the rules involved in financial coverage of DNA tests in order to make these available to all Europeans. Clear guidelines for the best practice will ensure that the provision of genetic services develops in a way that is beneficial to its customers, be they health professionals or the public, especially since the coordination of clinical, laboratory and research perspectives within a

    We present a brief overview of the incentive sensitization theory of addiction. This posits that addiction is caused primarily by drug-induced sensitization in the brain mesocorticolimbic systems that attribute incentive salience to reward-associated stimuli. If rendered hypersensitive, these systems cause pathological incentive motivation (‘wanting’) for drugs. We address some current questions including: what is the role of learning in incentive sensitization and addiction? Does incentive s...

    Life-history theory concerns the trade-offs that mold the patterns of investment by animals between reproduction, growth, and survival. It is widely recognized that physiology plays a role in the mediation of life-history trade-offs, but the details remain obscure. As life-history theory concerns aspects of investment in the soma that influence survival, understanding the physiological basis of life histories is related, but not identical, to understanding the process of aging. One idea from the field of aging that has gained considerable traction in the area of life histories is that life-history trade-offs may be mediated by free radical production and oxidative stress. We outline here developments in this field and summarize a number of important unresolved issues that may guide future research efforts. The issues are as follows. First, different tissues and macromolecular targets of oxidative stress respond differently during reproduction. The functional significance of these changes, however, remains uncertain. Consequently there is a need for studies that link oxidative stress measurements to functional outcomes, such as survival. Second, measurements of oxidative stress are often highly invasive or terminal. Terminal studies of oxidative stress in wild animals, where detailed life-history information is available, cannot generally be performed without compromising the aims of the studies that generated the life-history data. There is a need therefore for novel non-invasive measurements of multi-tissue oxidative stress. Third, laboratory studies provide unrivaled opportunities for experimental manipulation but may fail to expose the physiology underpinning life-history effects, because of the benign laboratory environment. Fourth, the idea that oxidative stress might underlie life-history trade-offs does not make specific enough predictions that are amenable to testing. Moreover, there is a paucity of good alternative theoretical models on which contrasting

This posits that addiction is caused primarily by drug-induced sensitization in the brain mesocorticolimbic systems that attribute incentive salience to reward-associated stimuli. If rendered hypersensitive, these systems cause pathological incentive motivation ('wanting') for drugs. We address some current questions including: what is the role of learning in incentive sensitization and addiction? Does incentive sensitization occur in human addicts? Is the development of addiction-like behaviour in animals associated with sensitization? What is the best way to model addiction symptoms using animal models? And, finally, what are the roles of affective pleasure or withdrawal in addiction?

    The objective of this review is to discuss definition, determinants, and management issues of the metabolic syndrome in children with a focus on South Asians. The literature search was done using the PubMed search engine (National Library of Medicine, Bethesda, MD, USA). Manual searches for other important references and medical databases were also done. There is a need for an integrated definition of the metabolic syndrome in children and adolescents, taking cognizance of the ethnic-specific variations. Obesity and body fat patterning are important determinants of insulin resistance and the metabolic syndrome in children and ethnic variations in these parameters are seen. Excess body fat and thicker truncal subcutaneous fat are important predisposing factors for development of insulin resistance in South Asian children. Because the metabolic syndrome tracks into adulthood, its manifestations need to be recognized early for prevention of diabetes and coronary heart disease. Therapeutic lifestyle changes, maintenance of high levels of physical activity and normal weight are most important strategies; pharmacologic therapy for individual components of the metabolic syndrome is occasionally needed. The metabolic syndrome in children is an important clinical marker of diabetes and coronary heart disease in adults. In view of the rapid increase in the metabolic syndrome in most populations, high-risk screening and effective public-intervention educational programs are urgently needed.

    Full Text Available The purpose of the study is to identify the main problems and prospects of development of palliative care in geriatrics at the present stage. Method of research was to analyze the printed and electronic databases that meet the stated issues. The results of the study highlight the problems of the development of palliative care in geriatric practice: the lack of a developed procedure of rendering palliative care and adequate elderly patient selection criteria, the lack of trained professional staff. The main prospects-association of palliative practices and concepts of modern geriatrics required specialized geriatric assessment and the provision of clinical, medical, social and socio-psychological geriatric syndromes. While promising option for the development of palliative care geriatrics is the integration into the existing health care system, acceptance of the fact that it is a part of the specialized geriatric care. This requires the involvement and training of not only specialists with medical education, but also persons without medical training from among social workers and volunteers working in palliative care. Therefore, the obtained data allowed to conclude that topical is the development of palliative care in geriatrics, taking into account not only clinical but medico-social, socio-psychological features.

  1. Transdisciplinarity: A Review of Its Origins, Development, and Current Issues

    2015-07-01

    Full Text Available Transdisciplinarity originated in a critique of the standard configuration of knowledge in disciplines in the curriculum, including moral and ethical concerns. Pronouncements about it were first voiced between the climax of government-supported science and higher education and the long retrenchment that began in the 1970s. Early work focused on questions of epistemology and the planning of future universities and educational programs. After a lull, transdisciplinarity re-emerged in the 1990s as an urgent issue relating to the solution of new, highly complex, global concerns, beginning with climate change and sustainability and extending into many areas concerning science, technology, social problems and policy, education, and the arts. Transdisciplinarity today is characterized by its focus on “wicked problems” that need creative solutions, its reliance on stakeholder involvement, and engaged, socially responsible science. In simultaneously studying multiple levels of, and angles on, reality, transdisciplinary work provides an intriguing potential to invigorate scholarly and scientific inquiry both in and outside the academy.

  2. Legal issues related to adolescent pregnancy: current concepts.

    1986-09-01

    Adolescent pregnancies have risen in recent years. Options open to the pregnant adolescent are: terminating the pregnancy; giving birth to the child out of wedlock; keeping the baby; giving the baby up for adoption; and marriage before or after the birth of the baby. Each of these options carries certain legal ramifications, since the adolescent patients have not reached the age of majority. The state or the parents usually assume the role of decision making on behalf of the adolescent or assist in the decision making process. Court rulings since the early seventies have legalized abortion and enlarged the rights of minors seeking termination of their pregnancies. Both parents and minors have rights under the certain state laws; parent have the right to notification, minors have the right to privacy. Keeping the child, out of wedlock, might result in legal battles over custody and/or establishing financial support from the father. Some adolescent mothers give up their children for adoption. There are 2 legal procedures that have to be accomplished before a child can be adopted: termination of the rights of the natural parents and adoption proceedings. If the parents marry after the birth of the child, the child is then considered legitimate and the father does not have to go through the process of adopting the child. Other issues requiring parental or individual consent include consent to treatment, contraception, or sterilization. In the case of forcible rape or incest, the physician is required to report incidents to law enforcement officials.

    This review provides an update and summary of recent neuropsychological findings in epilepsy focusing on three major clinical topics among the many developments in the field. We will critically outline the current state with regard to cognition in new-onset epilepsies, social cognition in epilepsy, and the long-term outcome of epilepsy surgery and the cognitive outcomes of superselective surgical procedures. Current studies indicate that neuropsychological impairments are prevalent already at the onset of epilepsy and even before, social cognition (i.e., emotion recognition and theory of mind) is impaired in different epilepsy populations, the long-term outcome of epilepsy surgery is mostly characterized by a stable or even improved cognitive status, and superselective epilepsy surgeries are associated with a promising neuropsychological outcome. The high prevalence of cognitive deficits around epilepsy onset challenges the assumption that epilepsy is the major cause of cognitive problems and calls for early neuropsychological diagnostics. Social cognition seems to be a relevant domain that is not yet routinely considered in epilepsy. The cognitive long-term outcome of epilepsy surgery is mostly positive. Stereotactic thermocoagulation and gamma knife surgery appear to be cognitively safe procedures.

    Full Text Available In recent years, much attention has been paid to the upper digestive tract diseases in children, particularly gastroesophageal reflux disease, as a cause that has an impact on the quality of life, even in children of school age, and thereafter in young adults. Consequently, there are searches for optimization of early detection, new me-thods of non-invasive diagnosis, screening of this pathology in children’s population in order to determine persons with risk factors and to control disease development and complicated course, as well as searches for the formation of preventive activities algorithm. Scientists came to a consensus that all examinations, which are used in pediatric practice, must be maximally available, simple and non-invasive to the extent of child’s condition. The question about advisability of performing esophagogastroduodenoscopy for all patients with complaints of heartburn and with other symptoms of gastroesophageal reflux disease, the question relative to performing ultrasonography of the esophagus in children as an additional method of examination, usage of questionnaire in pediatric practice, formation of disease course prediction algorithm, and identification of preventive measures specific to every patient remain open. In order to explain their application, the developmental mechanisms of this pathology must be well-understood, and individual risk factors that may influence disease severity and disease course prediction, which occur in children in different periods of life, must be taken into account. Therefore, the goal of this research is to provide an overview of modern literature with reference to topical issues of clinical evidence, risk factors, diagnosis, prediction of gastroesophageal reflux disease course in children of different ages (regarding main causative and pathogenic factors, clinical evidence (esophageal and extra-esophageal, diagnostic methods and modern approaches to gastroesophageal reflux disease

    Summary Background Medicine and biomedical sciences have become data-intensive fields, which, at the same time, enable the application of data-driven approaches and require sophisticated data analysis and data mining methods. Biomedical informatics provides a proper interdisciplinary context to integrate data and knowledge when processing available information, with the aim of giving effective decision-making support in clinics and translational research. Objectives To reflect on different perspectives related to the role of data analysis and data mining in biomedical informatics. Methods On the occasion of the 50th year of Methods of Information in Medicine a symposium was organized, that reflected on opportunities, challenges and priorities of organizing, representing and analysing data, information and knowledge in biomedicine and health care. The contributions of experts with a variety of backgrounds in the area of biomedical data analysis have been collected as one outcome of this symposium, in order to provide a broad, though coherent, overview of some of the most interesting aspects of the field. Results The paper presents sections on data accumulation and data-driven approaches in medical informatics, data and knowledge integration, statistical issues for the evaluation of data mining models, translational bioinformatics and bioinformatics aspects of genetic epidemiology. Conclusions Biomedical informatics represents a natural framework to properly and effectively apply data analysis and data mining methods in a decision-making context. In the future, it will be necessary to preserve the inclusive nature of the field and to foster an increasing sharing of data and methods between researchers. PMID:22146916

    Information Technology (IT) is a critical resource for improving today's business competitiveness. However, many healthcare providers do not proactively manage or improve the efficiency and effectiveness of their services with IT. Survival in a competitive business environment demands continuous improvements in quality and service, while rigorously maintaining core values. Electronic commerce continues its development, gaining ground as the preferred means of business transactions. Embracing e-healthcare and treating IT as a strategic tool to improve patient safety and the quality of care enables healthcare professionals to benefit from technology formerly used only for management purposes. Numerous improvement initiatives, introduced by both the federal government and the private sector, seek to better the status quo in IT. This paper examines the current IT climate using an enhanced "Built to Last" model, and comments on future IT strategies within the healthcare industry.

  8. Current issues of RNAi therapeutics delivery and development.

    Haussecker, D

    2014-12-10

    12 years following the discovery of the RNAi mechanism in Man, a number of RNAi therapeutics development candidates have emerged with profiles suggesting that they could become drugs of significant medical importance for diseases like TTR amyloidosis, HBV, solid cancers, and hemophilia. Despite this robust progress, the perception of RNAi therapeutics has been on a roller-coaster ride driven not only by science, but also regulatory trends, the stock markets, and Big Pharma business development decisions [1]. This presentation provides an update on the current state of RNAi therapeutics development with a particular focus on what RNAi delivery can achieve today and key challenges to be overcome to expand therapeutic opportunities. The delivery of RNAi triggers to disease-relevant cell types clearly represents the rate-limiting factor in broadly expanding the applicability of RNAi therapeutics. Today, with at least 3 delivery options (lipid nanoparticles/LNPs, GalNAc-siRNA conjugates, Dynamic PolyConjugates/DPCs) for which profound gene knockdowns have been demonstrated in non-human primates and in the clinic, RNAi therapeutics should in principle be able to address most diseases related to gene expression in the liver. Given the central importance of the liver in systemic physiology, this already represents a significant therapeutic and commercial opportunity rivaling that of e.g. monoclonal antibodies. Beyond the liver, there is a reason to believe that current RNAi therapeutics technologies can address a number of solid tumors (e.g. LNPs), diseases of the eye (e.g. self-delivering RNAi triggers) as well as diseases involving the respiratory epithelium (e.g. aerosolized LNPs), certain phagocytic cells (LNPs), hematopoietic stem cells and their progeny (lentiviral DNA-directed RNAi), vascular endothelial cells (cationic lipoplexes), and certain cell types in the kidney (self-delivering RNAi triggers, DPCs; Table 1). Despite this success, there has been a sense that

    Health advocacy is currently a key component of medical education in North America. In Canada, Health Advocate is one of the seven roles included in the Royal College of Physicians and Surgeons of Canada's CanMEDS competency framework. A literature search was undertaken to determine the current state of health advocacy in Canadian postgraduate medical education and to identify issues facing educators and learners with regards to health advocacy training. The literature revealed that the Health Advocate role is considered among the least relevant to clinical practice by educators and learners and among the most challenging to teach and assess. Furthermore learners feel their educational needs are not being met in this area. A number of key barriers affecting health advocacy education were identified including limited published material on the subject, lack of clarity within the role, insufficient explicit role modeling in practice, and lack of a gold standard for assessment. Health advocacy is defined and its importance to medical practice is highlighted, using pediatric emergency medicine as an example. Increased published literature and awareness of the role, along with integration of the new 2015 CanMEDS framework, are important going forward to address concerns regarding the quality of postgraduate health advocacy education in Canada.

    Despite growing concerns about the welfare of horses in Great Britain (GB) there has been little surveillance of the welfare status of the horse population. Consequently we have limited knowledge of the range of welfare problems experienced by horses in GB and the situations in which poor welfare occurs. Thirty-one in-depth interviews were conducted with a cross -section of equine stakeholders, in order to explore their perceptions of the welfare problems faced by horses in GB. Welfare problems relating to health, management and riding and training were identified, including horses being under or over weight, stabling 24 hours a day and the inappropriate use of training aids. The interviewees also discussed broader contexts in which they perceived that welfare was compromised. The most commonly discussed context was where horses are kept in unsuitable environments, for example environments with poor grazing. The racing industry and travellers horses were identified as areas of the industry where horse welfare was particularly vulnerable to compromise. Lack of knowledge and financial constraints were perceived to be the root cause of poor welfare by many interviewees. The findings give insight into the range of welfare problems that may be faced by horses in GB, the contexts in which these may occur and their possible causes. Many of the problems identified by the interviewees have undergone limited scientific investigation pointing to areas where further research is likely to be necessary for welfare improvement. The large number of issues identified suggests that some form of prioritisation may be necessary to target research and resources effectively.

    2017-06-01

    Full Text Available High risk Hodgkin lymphoma patients may occasionally have borderline characteristics similar to gray zone lymphomas and T-cell/histiocyte rich B cell lymphomas. These entities require different and more aggressive treatment modalities. Aggressive behavior is often associated with disturbances caused by Epstein Barr virus, or immune evasion caused by overexpression of check point inhibitors PDL-1 and PDL-2 coupled with the lack of expression of Class I and II MHC molecules. Galectin-1, TARC, sCD163 and other surrogate markers of immunosuppression in Hodgkin lymphoma may be useful for the assessment of treatment response. The improvements in lymphoma management diminished the importance of prognostic factors unified in the International Prognostic Scoring system, reducing them from 7 to 3 factors that remained relevant. Interim PET analysis is the only method able to identify resistant patients while chemotherapy is ongoing, thus enabling adjustment of treatment according to the treatment response. Efforts for stratification of patients according to disease histology, biology, microenvironment, clinical scoring systems and PET scan are ongoing. Current breakthroughs have set strong background for novel therapies with monoclonal antibodies and check point inhibitors that will result in improvement of management of high risk patients.

    2017-01-01

    Basic research in pharmaceutical sciences has a long and successful history. Researchers in this field have long given prime importance to the knowledge they have gained through their pharmaceutical education. The transition of pharmacy education to a 6-year course term has not only extended its duration but also placed more emphasis on practical clinical education. The School Education Act (in article 87, second paragraph) determines that "the term of the course, whose main purpose is to cultivate practical ability in clinical pharmacy, shall be six years" (excerpt). The 6-year pharmacy education is an exception to the general 4-year university term determined by the School Education Act. Therefore, the purpose of the 6-year course in pharmacy is clearly proscribed. This is true of the basic course in pharmaceutical education as well; hence, the basic course must be oriented toward developing "practical ability in clinical" education, too. The 6-year pharmacy course, starting from practice (Do), has evolved with the development of a syllabus that includes a model core curriculum (Plan). Furthermore, improvement in the course can be seen by the promoted development of faculty (Act). Now, evidence-based education research will be introduced (Check). This is how the Plan-Do-Check-Act cycle in pharmaceutical education is expected to work. Currently, pedagogy research in pharmacy education has just begun, so it is difficult to evaluate at this time whether basic pharmaceutical education does in fact contribute to enhancing the "practical clinical ability" component of pharmaceutical education.

    Full Text Available There is growing interest in carrying out further research to understand and reduce the impact of aircraft noise on airport neighborhood in anticipation of the projected substantial increase in global aviation. Soundscapes provide new analytical methods and a broader, more comprehensive appreciation of the aural environment, which may have a useful role in understanding noise-induced sleep disturbance and annoyance. Current noise metrics like Leq do not provide a common language to report noise environment to residents, which is a key obstacle to effective noise management and acceptance. Non-auditory effects complicate the production of consistent dose-response functions for aircraft noise affecting sleep and annoyance. There are various end-points that can be chosen to assess the degree of sleep disturbance, which has detracted from the clarity of results that has been communicated to wider audiences. The World Health Organization (WHO-Europe has produced Night Noise Guidelines for Europe, which act as a clear guide for airports and planners to work towards. Methodological inadequacies and the need for simpler techniques to record sleep will be considered with the exciting potential to greatly increase cost-effective field data acquisition, which is needed for large scale epidemiological studies

Analyzing the education given in the vocational schools in accordance with the national and international requirements, developing technologies and the needs of business world and making the necessary arrangements in line with these will contribute to the employability and preferability of graduates of these schools in an eff icient way. Many industrialists/businessmen in our country stated that they experienced serious problems in the supply of qualified staff with suff icient knowledge and skills needed in sectors. Although much progress has been achieved in this subject, it is a fact that there are still a lot of work to be done. In this study, current situation and main troubles in vocational schools are discussed in the light of the experiences gained at Hitit University Vocational School which was established about 40 years ago in Çorum and which is one of the first high schools in Turkey and some solutions are suggested in accordance with the problems mentioned.

    Subclinical hypothyroidism is defined as serum levels of TSH above the upper limit of the reference range, in the presence of normal concentrations of total T 4 or free T 4 . This biochemical profile might be an indication of mild hypothyroidism, with a potential increased risk of metabolic abnormalities and cardiovascular disease recorded among adults. Whether subclinical hypothyroidism results in adverse health outcomes among children is a matter of debate and so management of this condition remains challenging. Mild forms of untreated subclinical hypothyroidism do not seem to be associated with impairments in growth, bone health or neurocognitive outcome. However, ongoing scientific investigations have highlighted the presence of subtle proatherogenic abnormalities among children with modest elevations in their TSH levels. Although current findings are insufficient to recommend levothyroxine treatment for all children with mild asymptomatic forms of subclinical hypothyroidism, they highlight the potential need for assessment of cardiovascular risk among children with this condition. Increased understanding of the early metabolic risk factors associated with subclinical hypothyroidism in childhood will help to improve the management of affected individuals.

    Interventional pain management is a dynamic field with changes occurring on a daily basis, not only with technology but also with regulations that have a substantial financial impact on practices. Regulations are imposed not only by the federal government and other regulatory agencies, and also by a multitude of other payors, state governments and medical boards. Documentation of medical necessity with coding that correlates with multiple components of the patient's medical record, operative report, and billing statement is extremely important. Numerous changes which have occurred in the practice of interventional pain management in the new millennium continue to impact the financial viability of interventional pain practices along with patient access to these services. Thus, while complying with regulations of billing, coding and proper, effective, and ethical practice of pain management, it is also essential for physicians to understand financial aspects and the impact of various practice patterns. This article provides guidelines which are meant to provide practical considerations for billing and coding of interventional techniques in the management of chronic pain based on the current state of the art and science of interventional pain management. Hence, these guidelines do not constitute inflexible treatment, coding, billing or documentation recommendations. It is expected that a provider will establish a plan of care on a case-by-case basis taking into account an individual patient's medical condition, personal needs, and preferences, along with physician's experience and in a similar manner, billing and coding practices will be developed. Based on an individual patient's needs, treatment, billing and coding, different from what is outlined here is not only warranted but essential.

  20. The US Opioid Crisis: Current Federal and State Legal Issues.

    The United States is in the midst of a devastating opioid misuse epidemic leading to over 33,000 deaths per year from both prescription and illegal opioids. Roughly half of these deaths are attributable to prescription opioids. Federal and state governments have only recently begun to grasp the magnitude of this public health crisis. In 2016, the Centers for Disease Control and Prevention released their Guidelines for Prescribing Opioids for Chronic Pain. While not comprehensive in scope, these guidelines attempt to control and regulate opioid prescribing. Other federal agencies involved with the federal regulatory effort include the Food and Drug Administration (FDA), the Drug Enforcement Agency (DEA), and the Department of Justice. Each federal agency has a unique role in helping to stem the burgeoning opioid misuse epidemic. The DEA, working with the Department of Justice, has enforcement power to prosecute pill mills and physicians for illegal prescribing. The DEA could also implement use of prescription drug monitoring programs (PDMPs), currently administered at the state level, and use of electronic prescribing for schedule II and III medications. The FDA has authority to approve new and safer formulations of immediate- and long-acting opioid medications. More importantly, the FDA can also ask pharmaceutical companies to cease manufacturing a drug. Additionally, state agencies play a critical role in reducing overdose deaths, protecting the public safety, and promoting the medically appropriate treatment of pain. One of the states' primary roles is the regulation of practice of medicine and the insurance industry within their borders. Utilizing this authority, states can both educate physicians about the dangers of opioids and make physician licensure dependent on registering and using PDMPs when prescribing controlled substances. Almost every state has implemented a PDMP to some degree; however, in addition to mandating their use, increased interstate

    The aim of this article is to explore the current status of livestock resources, their status of utilisation and the future research concepts in dairy production and milk processing in Pakistan. Advances in the areas of genetics of dairy species, cow reproduction, nutrition, dairy chemistry, milk microbiology, processing technology and milk-based functional foods, have to be applied in Pakistan since the increase in Pakistan's population from 65 to 165 million over the past 3 decades is forecasted to an increase to 234 million by 2025. The need to increase food production means that competition for land and water resources will become more intense. The ecological sustainability of already fragile systems will be further challenged. Agro-industrial byproducts and non-conventional feed resources could be used for feeding of livestock, if farmers are trained accordingly. Situation may be significantly improved if fodder conservation techniques are introduced in livestock feeding systems. Pakistan needs a competitive and profitable dairy farming industry not just for economic but also environmental and social reasons. Productivity potential of local breeds is low and an attempt to genetically improve the local cattle through cross breeding has resulted in improvement in milk yield, acceleration in growth rates and higher prices; however, its discriminate use has been also associated with decreased immunity against temperature changes, disease and nutritional and environmental stresses prevailing in the region. The long-term effects of new systems (such as extended lactations, robot milking and all-year-round housing) will call for ever more intelligent approaches to the simultaneous achievement of quality systems that minimise environmental burdens, sustain high standards of health and welfare and deliver nutritionally valuable products into well organised food supply chains.

    The objectives of this study were (1) to evaluate the role of a full-time academic plastic surgeon, (2) to define the indicators predictive of a successful career in academic plastic surgery, and (3) to understand the current issues that will affect future trends in the practice of academic plastic surgery. A questionnaire was developed to evaluate the role of current full-time academic plastic surgeons and to understand the current issues and future challenges facing academic plastic surgery. Each plastic surgery program director in the United States was sent the survey for distribution among all full-time academic plastic surgeons. Over a 6-week period, responses from 143 full-time academic plastic surgeons (approximately 31%) were returned. Fifty-three percent of respondents had been academic plastic surgeons for longer than 10 years. Seventy-three percent of respondents defined academic plastic surgeons as clinicians who are teachers and researchers. However, 53% of respondents believed that academic plastic surgeons were not required to teach or practice within university hospitals/academic centers. The 3 factors reported most frequently as indicative of a successful career in academic plastic surgery were peer recognition, personal satisfaction, and program reputation. Dedication and motivation were the personal characteristics rated most likely to contribute to academic success. Forty-four percent of respondents were unable to identify future academic plastic surgeons from plastic surgery residency applicants, and 27% were not sure. Most (93%) of the respondents believed that academic surgery as practiced today will change. The overall job description of a full-time academic plastic surgeon remains unchanged (teacher and researcher). Whereas peer recognition, personal satisfaction, and program reputation were most frequently cited as indicative of a successful plastic surgery career, financial success was rated the least indicative. Similarly, whereas the

    On September 12, 2003, the University of Maryland School of Law's Intellectual Property and Law & Health Care Programs jointly sponsored and convened a roundtable discussion on the future public policy and ethical issues that will likely face the agricultural and microbial genomics sectors of the biotechnology industry. As this industry has developed over the last two decades, societal concerns have moved from what were often local issues, e.g., the safety of laboratories where scientists conducted recombinant DNA research on transgenic microbes, animals and crops, to more global issues. These newer issues include intellectual property, international trade, risks of genetically engineered foods and microbes, bioterrorism, and marketing and labeling of new products sold worldwide. The fast paced nature of the biotechnology industry and its new developments often mean that legislators, regulators and society, in general, must play ''catch up'' in their efforts to understand the issues, the risks, and even the benefits, that may result from the industry's new ways of conducting research, new products, and novel methods of product marketing and distribution. The goal of the roundtable was to develop a short list of the most significant public policy and ethical issues that will emerge as a result of advances in these sectors of the biotechnology industry over the next five to six years. More concretely, by ''most significant'' the conveners meant the types of issues that would come to the attention of members of Congress or state legislators during this time frame and for which they would be better prepared if they had well researched and timely background information. A concomitant goal was to provide a set of focused issues for academic debate and scholarship so that policy makers, industry leaders and regulators would have the intellectual resources they need to better understand the issues and concerns at stake.

    Full Text Available Africa is at a crossroads. It is now at the centre of development concerns that its leaders have been involved in for 50 years. These leaders are striving to find a happy outlet through which the black continent would be able play a role at the forefront of the world stage. A new generation of leaders has to be considered, who are capable of facing up to a number of challenges such as fragmentation of the region, history and knowledge, relaying the foundations of the post-colonial State, promotion of democracy and human rights and the implementation of new conditions for peace and freedom, the gauge of sustainable development. The ways in which these various challenges are tackled are crucial.

    There are substantial experiences in Croatia in the field of radioactive waste management concerning both the waste from nuclear applications and waste generated at nuclear power plant. The essential issue now is how set-up infrastructure and to realize institutional and capacity building to get adjusted to needs of the newly independent state. In connection to this, the issues related to national radioactive waste management strategy, past and new organization of the Regulatory Body, and changes in legislation and regulations are discussed. In addition, some on-going projects important for realization of a complete radioactive waste management in the country round up the present situation in the field of radioactive waste management in Croatia

  9. Modelling of residual stresses in valves Norem hard-facing alloys: a material characterization issue

    2011-01-01

    Replacement of cobalt-based hard-facing alloys (Stellite) is of high interest within the topic of reduction of human radiation exposure during field-work. Iron-based hard-facing alloys, such as Norem, are considered as good replacement candidates. Their wear characteristics are known to be quite equivalent to Stellite but are counter-balanced by lack of feedback in the field, especially about their resistance/toughness to brutal thermal shocks (60 C - 280 C for primary water). Norem alloys show a solid-solution strengthened austenitic dendrites matrix with a continuous network of eutectic and non-eutectic carbides at the grain boundaries. Toughness evaluation also requires information about residual stresses due to the welding (deposition) process: this work aims at furnishing tools for this purpose. First part of the work involved a microstructural study in order to compare the as-received material to other Norem samples previously observed in EDF's works and literature. A characterization of the different phase evolutions after heating and fast cooling of Norem is then made, in order to characterize whether metallurgical aspects have to be considered in the mechanical part during welding modelling: it appears that no strong solid-solid phase transformation may occur in welding situation. Tensile characterization is then performed on bulk PTAW (Plasma Transferred Arc Welding) specimens. A simplified welding simulation is eventually conducted on different axis-symmetric geometry and on real valve geometry in order to define a representative sample that will be used for further investigation on residual stresses.

    This review summarizes surface morphology changes of tungsten caused by heat and particle loadings from edge plasmas, and their effects on enhanced erosion and material lifetime in ITER and beyond. Pulsed heat loadings by transients (disruption and ELM) are the largest concerns due to surface melting, cracking, and dust formation. Hydrogen induced blistering is unlikely to be an issue of ITER. Helium bombardment would cause surface morphology changes such as W fuzz, He holes, and nanometric bubble layers, which could lead to enhanced erosion (e.g. unipolar arcing of W fuzz). Particle loadings could enhance pulsed heat effects (cracking and erosion) due to surface layer embrittlement by nanometric bubbles and solute atoms. But pulsed heat loadings alleviate surfaces morphology changes in some cases (He holes by ELM-like heat pulses). Effects of extremely high fluence (∼10 30 m −2 ), mixed materials, and neutron irradiation are important issues to be pursued for ITER and beyond. In addition, surface refurbishment to prolong material lifetime is also an important issue

  12. The management of high-level nuclear wastes - Issues politicians face regarding the risk of ionizing radiation

    The management of ionizing radiation is not a new issue, and it is not a subject that could be easily communicated with the general public. Politicians responsible for decision making are faced with the public who are concerned with the risks. Without general acceptance and support from the public, nuclear programs can not be pursued. The author provides three key guidelines for politicians to follow, the same advice given to the French Parliament earlier: addressing the protection of the population and environment in a responsible manner, assuming an open, non secretive and transparent approach, and adopting a democratic attitude to allow public participation in decision making

    This paper explores students' perceptions of blended learning modules delivered in a Continuing Professional Development (CPD) health care context in the UK. 'Blended learning' is the term used to describe a hybrid model of learning where traditional face-to-face teaching approaches and newer electronic learning activities and resources are utilised together. A new model of CPD for health care practitioners based on a blended learning approach was developed at a university in the south west of England. As part of the evaluation of the new modules, a qualitative study was conducted, in which 17 students who had experienced the modules were interviewed by telephone. Three main themes emerged from the interviews relating to the 'blended' nature of the blended learning modules. These were i) issues around the opportunities for discussion of online materials face-to-face; ii) issues of what material should be online versus face-to-face and iii) balancing online and face-to-face components. Teaching staff engaged in the development of blended learning courses need to pay particular attention to the ways in which they develop and integrate online and face-to-face materials. More attention needs to be paid to allowing opportunity for students to come together to create a 'community of inquiry'. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2004-04-01

    Leaders in the profession encourage academic health sciences librarians to assume new roles as part of the growth process for remaining vital professionals. Have librarians embraced these new roles? This research sought to examine from the reference librarians' viewpoints how their roles have changed over the past ten years and what the challenges these changes present as viewed by both the librarians and library directors. A series of eight focus groups was conducted with reference librarians from private and public academic health sciences libraries. Directors of these libraries were interviewed separately. Reference librarians' activities have largely confirmed the role changes anticipated by their leaders. They are teaching more, engaging in outreach through liaison initiatives, and designing Web pages, in addition to providing traditional reference duties. Librarians offer insights into unanticipated issues encountered in each of these areas and offer some creative solutions. Directors discuss the issues from their unique perspective. Librarians have identified areas for focusing efforts in lifelong learning. Adult learning theory, specialized databases and resources needed by researchers, ever-evolving technology, and promotion and evaluation of the library are areas needing attention. Implications for library education and continuing professional development are presented.

    2016-04-01

    The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

    International Nuclear Information System (INIS)

    Gilmore, M.C.; Kent, S.H.

    1993-01-01

    The purpose of this paper is to discuss and evaluate the issues that managing and operating contractors in the US DOE system should consider that are associated with management of radioactively contaminated elemental lead. There are many instances where DOE contaminated lead fall within Resource Conservation and Recovery Act (RCRA) regulation. In light of the Federal Facilities Compliance Act (FFCA), it is becoming increasingly important for additional regulatory options to be explored in order to facilitate proper treatment, storage and disposal of RCRA regulated lead. Various DOE facilities have initiated processes to reuse or recycle contaminated lead. Technologies such as melt-refining, surface blasting, and electromigration are being explored. One or more of these technologies may be the key to reducing contaminated lead inventories in the DOE system. Many DOE facilities are finding that these efforts need to have stringent regulatory evaluation since some alternatives have proven to be environmentally desirable but not economically feasible

    Mauger, A.; Armand, M.; Julien, C. M.; Zaghib, K.

    2017-06-01

    The commercial use of lithium metal batteries was delayed because of dendrite formation on the surface of the lithium electrode, and the difficulty finding a suitable electrolyte that has both the mechanical strength and ionic conductivity required for solid electrolytes. Recently, strategies have developed to overcome these difficulties, so that these batteries are currently an option for different applications, including electric cars. In this work, we review these strategies, and discuss the different routes that are promising for progress in the near future.

    2015-01-01

    The purpose of this study was to explore issues reported by caregivers of Head and Neck cancer (HNC) patients newly admitted to hospice homecare. 26 caregivers providing hospice homecare to patients with HNC were induded. Caregiver depressive symptoms, social support and perceived health data were analyzed. The caregivers reported few depressive symptoms, good perceived social support, and good perceived health; however, there was large variation in the group with some individuals having significant problems. Caregivers appeared to be doing well physically, emotionally and socially, but baseline data were used, so follow-up data are needed. Further research is warranted. Family caregivers also are affected by the experience of cancer and may have depressive symptoms needing assessment and management. Hospice patients with HNC have a variety of symptoms specific to their disease and treatment that need assessment and management by their family caregivers. Caregivers of HNC patients in hospice and palliative care need and deserve attention from hospice providers as they care for patients.

  5. Recycling issues facing target and RTL materials of inertial fusion designs

    2005-01-01

    Designers of heavy ion (HI) and Z-pinch inertial fusion power plants have explored the potential of recycling the target and recyclable transmission line (RTL) materials as an alternate option to disposal in a geological repository. This work represents the first time a comprehensive recycling assessment was performed on both machines with an exact pulse history. Our results offer two divergent conclusions on the recycling issue. For the HI concept, target recycling is not a 'must' requirement and the preferred option is the one-shot use scenario as target materials represent a small waste stream, less than 1% of the total nuclear island waste. We recommend using low-cost hohlraum materials once-through and then disposing of them instead of recycling expensive materials such as Au and Gd. On the contrary, RTL recycling is a 'must' requirement for the Z-pinch concept in order to minimize the RTL inventory and enhance the economics. The RTLs meet the low level waste and recycling dose requirements with a wide margin when recycled for the entire plant life even without a cooling period. While recycling offers advantages to the Z-pinch system, it adds complexity and cost to the HI designs

    Full Text Available The present paper aims to portray a clear perspective of the problem of immigrants, who are arriving in Europe from the Middle East conflict zones (particularly Syria and Iraq and from North Africa (mainly Libya. The causes that conducted to the development of such a phenomenon represent the motivation for choosing this theme, as well as its effects on the functionality of the EU at an institutional level and finally yet importantly the “trenchant” visions of the European public opinion, amplified by the mass media: the pros and cons of accepting the wave of refugees. The author's approach aims to put in balance both the positive effects of the phenomenon on the European continent, as well as the negative ones. Positive effects might consist in obtaining additional work force, as Europe is currently facing a demographic aging phenomenon. Furthermore, from the perspective of EU citizens, who believe in the cohesion of the European institutions, the acceptance of refugees represents a basic value for unity and further on stands for the formation of a homogenous European Union, therefore emphasising the importance of each individual. On the other hand, analysing the matter in the most realistic possible way, the risk of potential terrorist penetration in Europe is quite high and unmanageable. As a research method, we will use document analysis, referring to media articles and official documents. This phenomenon is particularly complex and the crisis result will depend on the effectiveness of the manner in which each national authority as well as the European ones will handle the issue.

    2016-06-01

    Electronic cigarettes (e-cigarettes) are currently unregulated nicotine delivery products, and use is increasing among youth and young adults in the U.S. Little is known about use in Mississippi. Surveys assessed e-cigarette use among Mississippi adolescents and adults. UMMC provided data on reported cases of e-cigarette poisonings. From 2010 to 2014, current e-cigarette use increased from 0.6% to 6.7% among middle school students, from 1.2% to 10.1% among high school students, and from 0.2% to 6.8% among adults. There were no reported cases of e-cigarette poisonings in 2010, 2011, or 2013. There was one case in 2012. Cases increased to 26 in 2014, and 17 cases were reported in 2015. E-cigarette use has increased substantially. E-cigarettes expose users and bystanders to harmful chemicals and cancer-causing compounds. Regulation of e-cigarettes at the local, state, and federal levels is needed to address the clear harms to non-smokers.

  8. Beyond privacy and exposure: ethical issues within citizen-facing analytics.

    Science.gov (United States)

    Grindrod, Peter

    2016-12-28

    We discuss the governing forces for analytics, especially concerning citizens' behaviours and their transactions, that depend on which of three spheres of operation an institution is in (corporate, public sector/government and academic). We argue that aspirations and missions also differ by sphere even as digital spaces have drawn these spheres ever closer together. We propose that citizens' expectations and implicit permissions for any exploitation of their data require the perception of a fair balance of benefits, which should be transparent (accessible to citizens) and justifiable. We point out that within the corporate sphere most analytics does not concern identity, targeted marketing nor any direct interference with individual citizens; but instead it supports strategic decision-making, where the data are effectively anonymous. With the three spheres we discuss the nature of models deployed in analytics, including 'black-box' modelling uncheckable by a human mind, and the need to track the provenance and workings or models. We also examine the recent evolution of personal data, where some behaviours, or tokens, identifying individuals (unique and yet non-random) are partially and jointly owned by other individuals that are themselves connected. We consider the ability of heavily and lightly regulated sectors to increase access or to stifle innovation. We also call for clear and inclusive definitions of 'data science and analytics', avoiding the narrow claims of those in technical sub-sectors or sub-themes. Finally, we examine some examples of unethical and abusive practices. We argue for an ethical responsibility to be placed upon professional data scientists to avoid abuses in the future.This article is part of the themed issue 'The ethical impact of data science'. © 2016 The Author(s).

    Informed consent has been proposed as the optimal method for ensuring the ethical entry of patients into clinical trials. However, it is known that problems with informed consent exist from the perspective of both patients and physicians. This has led to the suggestion that a third party, such as a research nurse or data manager, should be responsible for obtaining informed consent. The objective of this study was to explore the views of data managers concerning the nature, challenges, and rewards of their role and the similarities and differences between their role and that of physicians in obtaining informed consent. Four focus groups in three large teaching hospitals were conducted. Twenty-one data managers who were involved in cancer or pain clinical trials participated. The focus groups were audiotaped, transcribed, and subjected to content analysis to identify themes. Data managers identified three primary roles complementary to that of physicians: information provision, quality assurance of the informed consent process, and ongoing support during the trial. Despite expressed concern that medical and drug company interests may lead to subtle coercion of the patient, participants did not support the notion that they may be solely responsible for the consent process. Participants described a range of ethical dilemmas they confronted, including patients asking them for medical details they could not provide and situations in which they felt that informed consent was compromised in some way, for example, dealing with situations in which the patient appeared to be entering the trial for the wrong reasons due to misunderstanding, need, or passivity. Effective functioning of the multidisciplinary team assisted data managers in performing their role. A range of training needs were identified, particularly communication skills training and trial start-up briefing. The issues raised by these data managers have important implications for the successful conduct of

    Two-years of continuous observation of wind and current were carried out to investigate the relationship between them in the coastal waters off Tokai-mura, Ibaraki prefecture. Three instruments to measure the current were set in a thin surface layer of 3 m above the strong pycnocline, which is a common feature in coastal waters. Both of the power spectra of wind and currents showed very similar features, an outstanding high peak at 24-hour period and a range of high peaks longer than several-days period. The long term variation of the wind field always contained north-wind component, which contributed to forming the southward current along the shore throughout the year. A high correlation coefficient (0.64) was obtained between the wind and the current at a depth of 0.5 m on the basis of the two-year observation. Harmonic analysis revealed that an outstanding current with 24-hour period was the S 1 component (meteorological tide), and was driven by land and sea breezes. These breezes also contained solar tidal components such as K 1 , P 1 and S 2 . These wind components added their own wind driven currents on the original tidal currents. This meant that land and sea breezes generated wind driven currents with solar tidal periods which behaved like astronomical tidal currents. As result, coastal currents contained pseudo tidal currents which behaved like astronomical tidal currents. (author)

    The increase in pulse duration and cumulative run-time, together with the increase of the plasma energy content, will represent the largest changes in operation conditions in future fusion devices such as the International Thermonuclear Experimental Reactor (ITER) compared to today's experimental facilities. These will give rise to important plasma-physics effects and plasma-material interactions (PMIs) which are only partially observed and accessible in present-day experiments and will open new design, operation and safety issues. For the first time in fusion research, erosion and its consequences over many pulses (e.g., co-deposition and dust) may determine the operational schedule of a fusion device. This paper identifies the most critical issues arising from PMIs which represent key elements in the selection of materials, the design, and the optimisation of plasma-facing components (PFCs) for the first-wall and divertor. Significant advances in the knowledge base have been made recently, as part of the R and D supporting the engineering design activities (EDA) of ITER, and some of the most relevant data are reviewed here together with areas where further R and D work is urgently needed

  15. The use of conversation mapping to frame key perceptual issues facing the general dental practice system in England.

    To demonstrate the use of a novel qualitative methodology namely conversation mapping, which can be used to capture differences in stakeholder perspectives and give a root definition of the problem in a complex policy area. The methodology is used in the context of the changes introduced in the English general dental practice system in April 2006, to investigate the key issues facing the system, as perceived by general dental practitioners (GDPs). From a broad trigger statement, three transformational statements were produced. Each participant recorded their contribution on a hard diagrammatic form as a 'map', with others responding with their own written comment, thus generating three conversation maps. Thematic analysis resulted in the generation of a preliminary model summarising key perceptual issues. The five emergent themes identified were: financing, dentists' wants/needs, the role of the public and patients, system goals and policy level decision making. Financing was identified as the core category to which all other categories were related. Conversation mapping, a methodology arising from a systems approach, can be used to develop a 'rich picture' of an oral health care system in order to define the core problem within this policy area. Findings suggest that GDPs identify the financing of the system as a fundamental source of problems within the general dental practice system. This appears to be at variance with the perception of policy makers, who report a more limited view, identifying the system of remuneration as the 'heart of the problem'.

    There is a growing interest in the ethics of Health Policy and Systems Research (HPSR), and especially in areas that have particular ethical salience across HPSR. Hyder et al (2014) provide an initial framework to consider this, and call for more conceptual and empirical work. In this paper, we respond by examining the ethical issues that arose for researchers over the course of conducting three HPSR studies in Kenya in which health managers and providers were key participants. All three studies involved qualitative work including observations and individual and group interviews. Many of the ethical dilemmas researchers faced only emerged over the course of the fieldwork, or on completion, and were related to interactions and relationships between individuals operating at different levels or positions in health/research systems. The dilemmas reveal significant ethical challenges for these forms of HPSR, and show that potential 'solutions' to dilemmas often lead to new issues and complications. Our experiences support the value of research ethics frameworks, and suggest that these can be enriched by incorporating careful consideration of context embedded social relations into research planning and conduct. Many of these essential relational elements of ethical practice, and of producing quality data, are given stronger emphasis in social science research ethics than in epidemiological, clinical or biomedical research ethics, and are particularly relevant where health systems are understood as social and political constructs. We conclude with practical and research implications. © 2016 The Authors Developing World Bioethics Published by John Wiley & Sons Ltd.

    Newsome, Philip R H

    2003-04-01

    There can be few who would argue with the notion that the nature of dental practice in the United Kingdom has changed dramatically over the last couple of decades. A variety of factors, including new clinical techniques, growing consumerism, a much greater awareness of health-related and well-being issues in the public at large, as well as a marked deregulation within the dental profession, the development of vocational training and recently mandatory lifelong learning, the growing number of females working in the profession, and an increasing reluctance of young dentists to finance dental practices have all combined to create an environment which has enabled and encouraged a move away from traditional forms of dental care delivery. Instead, there has been considerable growth in independently-funded practice and a commensurate growth in the number of practices operating under a corporate body umbrella of one form or another. Currently there are 27 corporate bodies registered with the General Dental Council (GDC) with the likelihood of more in the future given the proposed GDC review. This will no doubt take into consideration European law, under which the restriction within the Dentist's Act on the number of corporate bodies is likely to be untenable. Although they still have only a small share of the dental market--with 4% of all dentists in the UK in 1999--they have expanded rapidly from a small base. The data available at the time the paper was written indicate that the global total of fees earned from dentistry in the UK in the financial year 2001/2002 was almost 3 billion Pounds, of which 1.9 billion Pounds (64%) came from NHS fees and 1.1 billion Pounds (36%) from private fees. Of this 1.9 billion Pounds received in NHS fees in 2001/2002, 0.55 billion Pounds were paid by patients who were not exempt from charges, bringing the total amount actually paid out of patients' pockets for dental treatment to 1.65 billion Pounds. Compare these figures with 1996

    Mirror self-recognition is often considered as an index of self-awareness. Neuroimaging studies have identified a neural circuit specialised for the recognition of one's own current facial appearance. However, faces change considerably over a lifespan, highlighting the necessity for representations of one's face to continually be updated. We used fMRI to investigate the different neural circuits involved in the recognition of the childhood and current, adult, faces of one's self. Participants viewed images of either their own face as it currently looks morphed with the face of a familiar other or their childhood face morphed with the childhood face of the familiar other. Activity in areas which have a generalised selectivity for faces, including the inferior occipital gyrus, the superior parietal lobule and the inferior temporal gyrus, varied with the amount of current self in an image. Activity in areas involved in memory encoding and retrieval, including the hippocampus and the posterior cingulate gyrus, and areas involved in creating a sense of body ownership, including the temporo-parietal junction and the inferior parietal lobule, varied with the amount of childhood self in an image. We suggest that the recognition of one's own past or present face is underpinned by different cognitive processes in distinct neural circuits. Current self-recognition engages areas involved in perceptual face processing, whereas childhood self-recognition recruits networks involved in body ownership and memory processing.

    A basic understanding of the ballistic behaviour of projectiles or fragments after entering the human body is essential for the head and neck surgeon in the military environment in order to anticipate the diagnostic and therapeutic consequences of this type of injury. Although a large number of factors influence the missile in flight and after penetration of the body, the most important factor is the amount of energy transmitted to the tissue. Long guns (rifles or shotguns) have a much higher muzzle energy compared to handguns, explaining why the remote effects beyond the bullet track play a major role. While most full metal jacket bullets release their energy after 12-20 cm (depending on the calibre), soft point bullets release their energy immediately after entry into the human body. This results in a major difference in extremity wounds, but not so much in injuries with long bullet paths (e.g. diagonal shots). Shrapnel wounds are usually produced with similarly high kinetic energy to those caused by hand- and long guns. However, fragments tend to dissipate the entire amount of energy within the body, which increases the degree of tissue disruption. Of all relevant injuries in the head and neck region, soft tissue injuries make up the largest proportion (60%), while injuries to the face are seen three times more often than injuries to the neck. Concomitant intracranial or spinal injury is seen in 30% of cases. Due to high levels of wound contamination, the infection rate is approximately 15%, often associated with a complicated and/or multiresistant spectrum of germs.

  10. Current signal of silicon detectors facing charged particles and heavy ions

    2005-07-01

    This work consisted in collecting and studying for the first time the shapes of current signals obtained from charged particles or heavy ions produced by silicon detectors. The document is divided into two main parts. The first consisted in reducing the experimental data obtained with charged particles as well as with heavy ions. These experiments were performed at the Orsay Tandem and at GANIL using LISE. These two experiments enabled us to create a data base formed of current signals with various shapes and various times of collection. The second part consisted in carrying out a simulation of the current signals obtained from the various ions. To obtain this simulation we propose a new model describing the formation of the signal. We used the data base of the signals obtained in experiments in order to constrain the three parameters of our model. In this model, the charge carriers created are regarded as dipoles and their density is related to the dielectric polarization in the silicon detector. This phenomenon induces an increase in permittivity throughout the range of the incident ion and consequently the electric field between the electrodes of the detector is decreased inside the trace. We coupled with this phenomenon a dissociation and extraction mode of the charge carriers so that they can be moved in the electric field. (author)

    A variety of health-related genetic testing is currently advertized directly to consumers. This article provides a timely overview of direct-to-consumer genetic testing (DTC GT) and salient ethical issues, as well as an analysis of the impact of the recently adopted regulation on in vitro diagnostic medical devices on DTC GT. DTC GT companies currently employ new testing approaches, report on a wide spectrum of conditions and target new groups of consumers. Such activities raise ethical issues including the questionable analytic and clinical validity of tests, the adequacy of informed consent, potentially misleading advertizing, testing in children, research uses and commercialization of genomic data. The recently adopted regulation on in vitro diagnostic medical devices may limit the offers of predisposition DTC GT in the EU market.

    2012-01-01

    This review evaluates the diagnostic criteria for three of the most common disorders for which children and adolescents are referred for mental health treatment: attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Although research supports the validity and clinical utility of these disorders, several issues are highlighted that could enhance the current diagnostic criteria. For ADHD, defining the core features of the disorder and its fit with other disorders, enhancing the validity of the criteria through the lifespan, considering alternative ways to form subtypes of the disorder, and modifying the age-of-onset criterion are discussed relative to the current diagnostic criteria. For ODD, eliminating the exclusionary criteria of CD, recognizing important symptom domains within the disorder, and using the cross-situational pervasiveness of the disorder as an index of severity are highlighted as important issues for improving classification. Finally, for CD, enhancing the current subtypes related to age of onset and integrating callous-unemotional traits into the diagnostic criteria are identified as key issues for improving classification.

    Over the past decade, educational programmes have been the main focus of the activities of the International Union of Toxicology (IUTOX). The IUTOX educational programmes are dynamic and have been growing in scope and frequency each year. It is envisaged that this growth will continue with guidance from our member societies and the continuing support of our sponsors. Presently, IUTOX is engaged in the following educational programmes: (1) International congresses that provide the opportunity for direct communication of current toxicological information. Fellowships are sponsored to facilitate attendance at these congresses for toxicologists in need. (2) Workshops that permit interaction on a more localised level of topics of more regional interest. Workshops have served to help stimulate formation of toxicology societies by bringing together sufficient scientists to facilitate these discussions. (3) Continuing educational (CE) programmes at member society meetings. Topics are prioritised based on input received from the local societies. Programmes often are those from CE courses given at meetings, such as conferences of the US Society of Toxicology (US SOT) and EUROTOX from the previous year. (4) Biennial Risk Assessment Summer School (RASS), an intensive week-long interaction between senior toxicologists who serve as faculty with attendees providing individual training. (5) Dissemination of donated printed toxicological books from publishers and syllabi from continuing education courses to regional locations. (6) Web-based interactive training programmes in regions where formal toxicological educational programmes are limited or lacking. (7) Preparation and distribution of monographs on selected topics of very current interest. Monographs on environmental oestrogens and genetically-modified foods have been published. The recent activities in each of these programmes are reviewed in this paper

The different entities of the AREVA Business Unit Logistics have indeed proven their ability to mobilize expertise at key steps of the waste logistical chain in supplying efficient, reliable and safe transport solutions. These entities constitute a world-wide transport network able to supply both tailor made and standardized solutions, under constant and strict compliance with international regulations. The AREVA Business Unit Logistics is indeed the only one player in the nuclear world able to cover the whole waste management policy with competencies at all technical levels. The next 10 years will be a cornerstone for waste management: industrial producers will have to cope with many challenges, such as larger flows of LLW and VLLW issued of dismantling operations. The AREVA Business Unit Logistics will be the partner of producers facing with them the future challenges, by improving current solutions and developing innovative solutions

    Full Text Available The transcranial application of weak currents to the human brain has enjoyed a decade of success, providing a simple and powerful tool for non-invasively altering human brain function. However, our understanding of current delivery and its impact upon neural circuitry leaves much to be desired. We argue that the credibility of conclusions drawn with tDCS is contingent upon realistic explanations of how tDCS works, and that our present understanding of tDCS limits the technique’s use to localize function in the human brain. We outline two central issues where progress is required: the localization of currents, and predicting their functional consequence. We encourage experimenters to eschew simplistic explanations of mechanisms of transcranial current stimulation. We suggest the use of individualized current modelling, together with computational neurostimulation to inform mechanistic frameworks in which to interpret the physiological impact of tDCS. We hope that through mechanistically richer descriptions of current flow and action, insight into the biological processes by which transcranial currents influence behaviour can be gained, leading to more effective stimulation protocols and empowering conclusions drawn with tDCS.

  3. Empowering the Legitimacy of Municipal Decision-Making - Three Swedish Municipalities Facing the Nuclear Waste Management Issue

    2001-01-01

    This paper is focussed on how municipal elected leaders in three Swedish feasibility study municipalities - Nykoeping, Oskarshamn and Tierp - have tried to ensure that future decisions by their respective municipalities will be based both on factual knowledge and on existing opinions held by the general public. These efforts have contributed to an empowerment of the legitimacy of municipal decision-making within the nuclear waste management field and, probably, also served as a factor contributing to trust building with regard to these issues. The three cases show three ways to handle the problem, although there are also common features. The municipalities of Nykoeping and Oskarshamn have been facing these issues since 1995. In the case of Tierp, the municipality was confronted in late 1998 with the task to choose a strategy for its involvement in the site selection process and then, immediately, implement that strategy. A decision to construct a final repository for spent nuclear fuel has an obvious local dimension. It is not enough that an implementer is capable of developing a method that is considered to be safe enough by the regulatory authorities and by the Government. Nor is it enough that the implementer has succeeded to choose a site that these institutions consider to be suitable. A vital condition for a successful result is also that the general public, especially people living close to the site, have trust in the process leading up to the decision - and of course also that the general public is confident that the implementer and the regulator have agreed on a sound technical solution of the disposal problem. In other words, decisions in this area by Government and regulatory authorities do not only have to comply with existing legislation (obviously decisions by such bodies have to be 'legal'); they also should have a democratic legitimacy. In a representative democracy like Sweden, with high voting participation, it may seem self-evident that the

    Food allergy is a major health problem of increasing concern. The insufficiency of protein sources for human nutrition in a world with a growing population is also a significant problem. The introduction of new protein sources into the diet, such as newly developed innovative foods or foods produced using new technologies and production processes, insects, algae, duckweed, or agricultural products from third countries, creates the opportunity for development of new food allergies, and this in turn has driven the need to develop test methods capable of characterizing the allergenic potential of novel food proteins. There is no doubt that robust and reliable animal models for the identification and characterization of food allergens would be valuable tools for safety assessment. However, although various animal models have been proposed for this purpose, to date, none have been formally validated as predictive and none are currently suitable to test the allergenic potential of new foods. Here, the design of various animal models are reviewed, including among others considerations of species and strain, diet, route of administration, dose and formulation of the test protein, relevant controls and endpoints measured.

    After the president Eisenhower's 'Atoms for Peace' speech at the UN general Conference in December 1953, nuclear industry for peaceful uses of nuclear energy has been developed steadily worldwide through international co-operation and collaboration during last half a century. However, from late 1980s, in particular, after Chernobyl nuclear accident in 1986 and growing public opposition on nuclear waste management and disposal, the growth of nuclear power plants worldwide, except some Asian countries, has been slowed down. Nuclear power currently supplies about 16 % of the world's electricity. In the next 50 years, it is expected that the world energy demand will increase about two times comparing current level while electricity demand will be tripled. Therefore, the nuclear industry should be expanded significantly in the next 50 years to meet the role for 'Prosperity beyond Peace'. The main issues for nuclear industry to take this important role are to increase in economics of nuclear power, and to resolve nuclear waste management and disposal. Some of these issues have been resolved mainly through international co-operation. For example, there are significant efforts to improve economics of nuclear power. This paper reviews worldwide efforts to resolve these issues and mentions what are the remaining ones

    Deep brain stimulation has become a well-established symptomatic treatment for Parkinson's disease during the last 25 years. Besides improving motor symptoms and long-term motor complications, positive effects on patients' mobility, activities of daily living, emotional well-being and health-related quality of life have been recognized. Apart from that, numerous clinical trials analyzed effects on non-motor symptoms and side effects of deep brain stimulation. Several technical issues and stimulation paradigms have been and are still being developed to optimize the therapeutic effects, minimize the side effects and facilitate handling. This review summarizes current therapeutic issues, i.e., patient and target selection, surgical procedure and programming paradigms. In addition it focuses on neuropsychological effects and side effects of deep brain stimulation.

It will be open to the world in 2014. The government's long term goal is to make the center a hub for education and training in the nuclear field in Asia. The ITC will accomplish this by establishing facilities for practical and realistic exercises through the use of a test bed and various other experiments. The center will also provide comprehensive educational programs for nuclear newcomers. Its main programs include: a well designed educational program, customized training courses, and on-the-job training. This paper will discuss the current status of the ITC and describe practical plans for solving current security issues in Korea. (authors)

The security of any future Smart Grid is dependent on successfully addressing the cyber security issues associated with the nation’s current power grid. Smart Grid will utilize numerous legacy systems and technologies that are currently installed. Therefore, known vulnerabilities in these legacy systems must be remediated and associated risks mitigated in order to increase the security and success of the Smart Grid. The implementation of Smart Grid will include the deployment of many new technologies and multiple communication infrastructures. This report describes the main technologies that support Smart Grid and summarizes the status of implementation into the existing U.S. electrical infrastructure.

    The United States Public Law 480 Title II food aid program is the largest U.S. government program directed at reducing hunger, malnutrition, and food insecurity in the developing world. USAID and Title II implementing partners face challenges in measuring the success of Title II programs in reducing household food insecurity because of the technical difficulty and cost of collecting and analyzing data on traditional food security indicators, such as per capita income and caloric adequacy. The Household Food Insecurity Access Scale (HFIAS) holds promise as an easier and more user-friendly approach for measuring the access component of household food security. To support the consistent and comparable collection of the HFIAS, efforts are under way to develop a guide with a standardized questionnaire and data collection and analysis instructions. A set of domains have been identified that is deemed to capture the universal experience of the access component of household food insecurity across countries and cultures. Based on these domains, a set of questions has been developed with wording that is deemed to be universally appropriate, with minor adaptation to local contexts. These underlying suppositions, based on research in multiple countries, are being verified by potential users of the guide. The key remaining issue relates to the process for creating a categorical indicator of food insecurity status from the HFIAS.

    1997-04-01

    Electrochemical capacitors are a candidate for traction power assists in hybrid electric vehicles (HEVs). Other advanced automotive applications, while not the primary focus of current development efforts, are also possible. These include load leveling high-energy batteries, power conditioning electronics, electrically hated catalysts, electric power steering, and engine starter power. Higher power and longer cycle life are expected for electrochemical capacitors than for batteries. Evaluation of environmental, health, and safety (EH and S) issues of electrochemical capacitors is an essential part of the development and commercialization of electrochemical capacitors for advanced vehicles. This report provides an initial EH and S assessment. This report presents electrochemical capacitor electrochemistry, materials selection, intrinsic material hazards, mitigation of those hazards, environmental requirements, pollution control options, and shipping requirements. Most of the information available for this assessment pertains to commercial devices intended for application outside the advanced vehicle market and to experiment or prototype devices. Electrochemical capacitors for power assists in HEVs are not produced commercially now. Therefore, materials for advanced vehicle electrochemical capacitors may change, and so would the corresponding EH and S issues. Although changes are possible, this report describes issues for likely electrochemical capacitor designs.

    The main purpose of radiation research is to understand the biological effects of radiation exposure to humans, the molecular mechanisms of biological response m organisms, and its sale application for medical and industrial use. In order to know the current state or education on fundamentals of radiology including radiation biology, a nation-wide questionnaire survey had been performed at medical schools and different co-medical courses in Japanese universities, during the period of 2004 and 2005. The survey results showed: (1) Difference in teaching hours for education on radiation between medical schools with and without department or division of radiation biology or radiation-related field. (2) Teaching hours for education on radiation in nursing course were very limited among the co-medical courses. Although, some improvement have been found about the state of education on radiation risk at medical schools, after the disaster of nuclear accident at Fukushima No.1 Nuclear Power Plant of TEPCO in March 2011. However, still much more effort t is needed to improve basic education on radiation. Science Council of Japan issued the recommendation on September 4, 2014 'Making radiation health risk education compulsory in medical education'. The working group for this purpose was set up under the Council of Head of National Medical Schools of Japan, on January 28, 2015.

    We review the status of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements and the CP-violating phases in the CKM-unitarity triangle. The emphasis in these lecture notes is on B-meson physics, through we also review the current status and issues in the light quark sector of this matrix. Selected applications of theoretical methods in QCD used in the interpretation of data are given and some of the issues restricting the theoretical precision on the CKM matrix elements discussed. The overall consistency of the CKM theory with the available data in flavour physics is impressive and we quantify this consistency. Current data also show some anomalies which, however, are not yet statistically significant. They are discussed briefly. some benchmark measurements that remain to be done in experiments at the B-factories and hadron colliders are listed. Together with the already achieved results, they will provide unprecedented test of the CKM theory and by the same token may lead to the discovery of new physics. (Author) 284 refs

    2004-01-01

    The environmental barrier coating (EBC) for SiC/SiC ceramic matrix composites and Si3N4 ceramics is an emerging field as the application of silicon-based ceramics in the gas turbine engine hot section is on the horizon, both for aero and industrial gas turbines. EBC is an enabling technology for silicon-based ceramics because these materials without an EBC cannot be used in combustion environments due to rapid surface recession. Significant progress in EBC development has been made during the last decade through various government-sponsored programs. Current EBCs are based on silicon, mullite (3Al2O3-2SiO2) and BSAS (barium strontium aluminum silicate with celsian structure). Volatility of BSAS, BSAS-silica chemical reaction, and low melting point of silicon limit temperature capability of current EBCs to about 1350 C for long-term applications. There is a need for higher temperature EBCs as the temperature capability of silicon-based ceramics continue to increase. Therefore, research is underway to develop EBCs with improved temperature capability compared to current EBCs. The current status and issues with the advanced EBC development efforts will be discussed.

  9. Implications of Current Ecological Thinking for Biodiversity Conservation: a Review of the Salient Issues

    Full Text Available Given escalating concern worldwide about the loss of biodiversity, and given biodiversity's centrality to quality of life, it is imperative that current ecological knowledge fully informs societal decision making. Over the past two decades, ecological science has undergone many significant shifts in emphasis and perspective, which have important implications for how we manage ecosystems and species. In particular, a shift has occurred from the equilibrium paradigm to one that recognizes the dynamic, non-equilibrium nature of ecosystems. Revised thinking about the spatial and temporal dynamics of ecological systems has important implications for management. Thus, it is of growing concern to ecologists and others that these recent developments have not been translated into information useful to managers and policy makers. Many conservation policies and plans are still based on equilibrium assumptions. A fundamental difficulty with integrating current ecological thinking into biodiversity policy and management planning is that field observations have yet to provide compelling evidence for many of the relationships suggested by non-equilibrium ecology. Yet despite this scientific uncertainty, management and policy decisions must still be made. This paper was motivated by the need for considered scientific debate on the significance of current ideas in theoretical ecology for biodiversity conservation. This paper aims to provide a platform for such discussion by presenting a critical synthesis of recent ecological literature that (1 identifies core issues in ecological theory, and (2 explores the implications of current ecological thinking for biodiversity conservation.

    Medicare Part D was introduced with a goal of providing access to prescription drug coverage for all Medicare beneficiaries. Regulatory mandates and the changing landscape of health care require continued evaluation of the state of the Part D benefit. To review the current state of plan offerings and highlight key issues regarding the administration of the Part D benefit. The Part D drug benefit continues to evolve. The benefit value appears to be diluted compared to the benefit value of large employer plans. Regulatory restrictions mandated by the Centers for Medicare and Medicaid Services (CMS) are reported to inhibit the ability of plans to create an effective, competitive drug benefit for Medicare beneficiaries. Management in this restrictive environment impedes competitive price negotiations and formulary coverage issues continue to create confusion especially for patients with chronic diseases. The doughnut hole coverage gap represents a significant cost-shifting issue for beneficiaries that may impact medication adherence and persistence. To address these and other challenges, CMS is working to improve the quality of care for Part D beneficiaries by designing and supporting demonstration projects. Although these projects are in different stages, all stakeholders are hopeful that they will lead to the development of best practices by plans to help manage their beneficiaries more efficiently. A significant number of Medicare beneficiaries are currently receiving prescription drug benefits through Part D. The true value of this benefit has been called into question as a result of plan design parameters that lead to cost-shifting, an increasing burden for enrollees. Concerns regarding the ability to provide a competitive plan given the stringent rules and regulations have been voiced by plan administrators. In an effort to drive toward evidence-based solutions, CMS is working to improve the overall quality of care through numerous demonstration projects.

    2014-01-01

    Full Text Available Transcranial Direct Current Stimulation (tDCS is a neuromodulatory device often publicized for its ability to enhance cognitive and behavioral performance. These enhancement claims, however, are predicated upon electrophysiological evidence and descriptions which are far from conclusive. In fact, a review of the literature reveals a number of important experimental and technical issues inherent with this device that are simply not being discussed in any meaningful manner. In this paper, we will consider five of these topics. The first, inter-subject variability, explores the extensive between- and within-group differences found within the tDCS literature and highlights the need to properly examine stimulatory response at the individual level. The second, intra-subject reliability, reviews the lack of data concerning tDCS response reliability over time and emphasizes the importance of this knowledge for appropriate stimulatory application. The third, sham stimulation and blinding, draws attention to the importance (yet relative lack of proper control and blinding practices in the tDCS literature. The fourth, motor and cognitive interference, highlights the often overlooked body of research that suggests typical behaviors and cognitions undertaken during or following tDCS can impair or abolish the effects of stimulation. Finally, the fifth, electric current influences, underscores several largely ignored variables (such as hair thickness and electrode attachments methods influential to tDCS electric current density and flow.Through this paper, we hope to increase awareness and start an ongoing dialogue of these important issues which speak to the efficacy, reliability, and mechanistic foundations of tDCS.

    To investigate the comparative effectiveness of current standard treatment, against an individually tailored behavioural programme delivered via the Internet or face-to-face for people with acute whiplash associated disorders. A multicentre, randomized, three-group design, with concealed allocation. A total of 55 participants (37 female), age 18-65, with acute Whiplash Associated Disorder (Grade I-II), recruited at two emergency clinics in Sweden. Before randomization all participants received standard self-care instructions. The Internet and face-to-face groups followed a seven-week behavioural programme involving individual tailoring, via email (Internet group), or in sessions at a physical therapy unit (face-to-face group). The control group only received the self-care instructions. Pain-related disability, pain intensity, self-efficacy in daily activities, catastrophizing and fear of movement/(re)injury. Assessments were performed at baseline (2-4 weeks postinjury) and at three, six and 12 months postintervention. Both the Internet (n = 16) and face-to-face (n = 14) group showed a larger decrease in pain-related disability than the control group (n = 16); -12 and -11, respectively, compared with -5 in the control group at 12-months follow-up. Significant differences between the groups in overall treatment effect were shown in all outcomes except pain intensity. All groups improved significantly over time in all outcomes, except for fear of movement/(re)injury and catastrophizing in the control group. An individually tailored behavioural programme improved biopsychosocial factors in patients with whiplash associated disorders up to 12 months after treatment. Internet-delivered intervention was as effective as clinic-based face-to-face therapy sessions. © The Author(s) 2015.

    Duncker, James J.; Johnson, Kevin K.

    2015-10-28

    The Chicago Area Waterway System (CAWS) consists of a combination of natural and manmade channels that form an interconnected navigable waterway of approximately 90-plus miles in the metropolitan Chicago area of northeastern Illinois. The CAWS serves the area as the primary drainage feature, a waterway transportation corridor, and recreational waterbody. The CAWS was constructed by the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC). Completion of the Chicago Sanitary and Ship Canal (initial portion of the CAWS) in 1900 breached a low drainage divide and resulted in a diversion of water from the Lake Michigan Basin. A U.S. Supreme Court decree (Consent Decree 388 U.S. 426 [1967] Modified 449 U.S. 48 [1980]) limits the annual diversion from Lake Michigan. While the State of Illinois is responsible for the diversion, the MWRDGC regulates and maintains water level and water quality within the CAWS by using several waterway control structures. The operation and control of water levels in the CAWS results in a very complex hydraulic setting characterized by highly unsteady flows. The complexity leads to unique gaging requirements and monitoring issues. This report provides a general discussion of the complex hydraulic setting within the CAWS and quantifies this information with examples of data collected at a range of flow conditions from U.S. Geological Survey streamflow gaging stations and other locations within the CAWS. Monitoring to address longstanding issues of waterway operation, as well as current (2014) emerging issues such as wastewater disinfection and the threat from aquatic invasive species, is included in the discussion.

    2014-01-01

    Domestic violence is currently an issue of great political and social importance. The real incidence of domestic violence is difficult to determine due to the environment where it takes place and the reluctance of victims to report abuse. On the other hand, all types of violence represent an important public health problem. We report the case of a young woman who presented with thromboembolic phenomena at different sites due to domestic violence. We emphasize that it is necessary for radiologists and other healthcare professionals to consider the possibility of domestic violence when establishing the diagnosis. This can be important for determining the incidence of abuse, diminishing its sequela, and help increase its reporting. Copyright © 2011 SERAM. Published by Elsevier Espana. All rights reserved.

  19. Exploring the Benefits of Respite Services to Family Caregivers: Methodological Issues and Current Findings

    2017-01-01

    Objectives There is growing emphasis on empirical validation of the efficacy of community-based services for older people and their families, but research on services such as respite care faces methodological challenges that have limited the growth of outcome studies. We identify problems associated with the usual research approaches for studying respite care, with the goal of stimulating use of novel and more appropriate research designs that can lead to improved studies of community-based services. Method Using the concept of research validity, we evaluate the methodological approaches in the current literature on respite services, including adult day services, in-home respite and overnight respite. Results Although randomized control trials (RCTs) are possible in community settings, validity is compromised by practical limitations of randomization and other problems. Quasi-experimental and interrupted time series designs offer comparable validity to RCTs and can be implemented effectively in community settings. Conclusion An emphasis on RCTs by funders and researchers is not supported by scientific evidence. Alternative designs can lead to development of a valid body of research on community services such as respite. PMID:26729467

  20. Phytosanitary irradiation of fresh tropical commodities in Hawaii: Generic treatments, commercial adoption, and current issues

    Follett, Peter A.; Weinert, Eric D.

    2012-01-01

    Hawaii is a pioneer in the use of phytosanitary irradiation. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping papaya and other tropical fruits and vegetables to the United States mainland using irradiation for 11 years. Irradiation is an approved treatment to control quarantine pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5500 t). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) will accelerate commodity export approvals and facilitate worldwide adoption. Lowering doses for specific pests and commodities can lower treatment costs and increase capacity owing to shorter treatment times, and will minimize any quality problems. Current impediments to wider adoption include the 1 kGy limit for fresh horticultural products, the labeling requirement, and non-acceptance of phytosanitary irradiation in Japan, the European Union, and elsewhere. Irradiation has potential as a treatment for unregulated imports to prevent new pest incursions. - Highlights: ► Irradiation is used to control quarantine insects in exported fresh commodities. ► Hawaii exported 5.7 t of tropical produce using irradiation in 2010. ► Generic radiation treatments will accelerate commodity export approvals. ► Lowering the dose for specific commodities will reduce costs/maintain quality. ► Current issues include the 1 kGy dose limit and labeling requirements.

    Supporting clinicians in decision making using advanced technologies has been an active research area in biomedical engineering during the past years. Among a wide range of ubiquitous systems, smartphone applications have been increasingly developed in healthcare settings to help clinicians as well as patients. Today, many smartphone applications, from basic data analysis to advanced patient monitoring, are available to clinicians and patients. Such applications are now increasingly integrating into healthcare for clinical decision support, and therefore, concerns around accuracy, stability, and dependency of these applications are rising. In addition, lack of attention to the clinicians' acceptability, as well as the low impact on the medical professionals' decision making, are posing more serious issues on the acceptability of smartphone applications. This article reviews smartphone-based decision support applications, focusing on hospital care settings and their overall impact of these applications on the wider clinical workflow. Additionally, key challenges and barriers of the current ubiquitous device-based healthcare applications are identified. Finally, this article addresses current challenges, future directions, and the adoption of mobile healthcare applications.

    Transfusion medicine holds a place of prime importance in organ transplant surgeries. There is a huge demand of organs worldwide with long waiting periods before the organ is available for transplant. Currently the dependency on ABO and HLA matching has decreased considerably with the use of modern immunosuppressant drugs and transplant techniques. The greatest advance in clinical implementation of ABO-incompatible transplants came about through desensitization and isoagglutinin elimination techniques with immunoadsorption and anti-CD20 antibodies becoming the norm, and spleenectomy fading out. The implications and practices of transfusion medicine in organ transplant are also undergoing drastic changes. The practice of infusion of one unit of donor's blood preoperatively for immunomodulation is no longer practiced. Use of leuco-reduced products has shown decreasing trends of alloimmunization and graft rejection in cases of multiple surgeries related to organ transplants. Worldwide donor and recipient registry programmes are being setup and existing ones are being upgraded. Such a registry system has been opened in India for kidney transplant cases very recently. Due to such registry programmes the dependency on siblings and directed donations have decreased considerably. This review deals with some of the current issues contributing to the successful outcome of mismatched transplants and the changing concepts of transfusion medicine related to it.

    This article overviews current funding and financing issues in the Australian hospice and palliative care sector. Within Australia, the major responsibilities for managing the health care system are shared between two levels of government. Funding arrangements vary according to the type of care. The delivery of palliative care services is a State/Territory responsibility. Recently, almost all States/Territories have developed overarching frameworks to guide the development of palliative care policies, including funding and service delivery structures. Palliative care services in Australia comprise a mix of specialist providers, generalist providers, and support services in the public, nongovernment, and private sectors. The National Palliative Care Strategy is a joint strategy of the Commonwealth and States that commenced in 2002 and includes a number of major issues. Following a national study in 1996, the Australian National Subacute and Nonacute Patient (AN-SNAP) system was endorsed as the national casemix classification for subacute and nonacute care. Funding for palliative care services varies depending on the type of service and the setting in which it is provided. There is no national model for funding inpatient or community services, which is a State/Territory responsibility. A summary of funding arrangements is provided in this article. Palliative care continues to evolve at a rapid rate in Australia. Increasingly flexible evidence-based models of care delivery are emerging. This article argues that it will be critical for equally flexible funding and financing models to be developed. Furthermore, it is critical that palliative care patients can be identified, classified, and costed. Casemix classifications such as AN-SNAP represent an important starting point but further work is required.

    In studies publishing identifying personal information, obtaining consent is regarded as necessary, as it is impossible to ensure complete anonymity. However, current journal practices around specific points to consider when obtaining consent, the contents of consent forms and how consent forms are managed have not yet been fully examined. This study was conducted to identify potential issues surrounding consent to publish identifying personal information. Content analysis was carried out on instructions for authors and consent forms developed by academic journals in four fields (as classified by Journal Citation Reports): medicine general and internal, genetics and heredity, pediatrics, and psychiatry. An online questionnaire survey of editors working for journals that require the submission of consent forms was also conducted. Instructions for authors were reviewed for 491 academic journals (132 for medicine general and internal, 147 for genetics and heredity, 100 for pediatrics, and 112 for psychiatry). Approximately 40% (203: 74 for medicine general and internal, 31 for genetics and heredity, 58 for pediatrics, and 40 for psychiatry) stated that subject consent was necessary. The submission of consent forms was required by 30% (154) of the journals studied, and 10% (50) provided their own consent forms for authors to use. Two journals mentioned that the possible effects of publication on subjects should be considered. Many journal consent forms mentioned the difficulties in ensuring complete anonymity of subjects, but few addressed the study objective, the subjects' right to refuse consent and the withdrawal of consent. The main reason for requiring the submission of consent forms was to confirm that consent had been obtained. Approximately 40% of journals required subject consent to be obtained. However, differences were observed depending on the fields. Specific considerations were not always documented. There is a need to address issues around the study

    Raimbault, P.

    2002-01-01

    Deep geological disposal of high level and medium level long-lived waste in France is one of the three research paths defined by the law of 30th December 1991 on radioactive waste management. Research should be undertaken on: separation and transmutation of long-lived radionuclides in these waste; reversible or non reversible disposal in deep geological layers supported by investigations in underground laboratories; processes for conditioning and long term surface storage of these waste. In 2006, a global evaluation report on this research should be established by the Government and sent to the French Parliament. On this basis the Parliament should promulgate a law providing new objectives for the research and possibly presenting a framework for a deep disposal process. The French Nuclear Safety Authority has the responsibility to license the underground laboratories foreseen in the second research path and the nuclear facilities involved in the first and third research paths and make sure that existing high level and medium level long-lived waste currently produced are properly managed. It will give its advice on the safety aspects associated to the envisaged future management options. Its main concern is that results obtained in 2006 will be conclusive enough to take decisions for future orientations. Concerning the deep disposal option, under the responsibility of ANDRA (Agence Nationale pour la gestion des Dechets RAdioactifs), the construction of an underground laboratory has been authorized on the Bure site, in eastern France, and the shafts are under construction. The main issue is the level of investigations that may be performed in the host rock in order to support the feasibility study of a disposal concept on this site. Other issues are the elaboration of new safety standards to set a framework for a safety assessment of a disposal concept, the specifications for acceptance of waste packages in a future deep disposal, and relation of safety matters with

    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.

    In March 2005, a group of experts from the European Society of Human Genetics and European Society of Human Reproduction and Embryology met to discuss the interface between genetics and assisted reproductive technology (ART), and published an extended background paper, recommendations and two Editorials. Seven years later, in March 2012, a follow-up interdisciplinary workshop was held, involving representatives of both professional societies, including experts from the European Union Eurogentest2 Coordination Action Project. The main goal of this meeting was to discuss developments at the interface between clinical genetics and ARTs. As more genetic causes of reproductive failure are now recognised and an increasing number of patients undergo testing of their genome before conception, either in regular health care or in the context of direct-to-consumer testing, the need for genetic counselling and preimplantation genetic diagnosis (PGD) may increase. Preimplantation genetic screening (PGS) thus far does not have evidence from randomised clinical trials to substantiate that the technique is both effective and efficient. Whole-genome sequencing may create greater challenges both in the technological and interpretational domains, and requires further reflection about the ethics of genetic testing in ART and PGD/PGS. Diagnostic laboratories should be reporting their results according to internationally accepted accreditation standards (International Standards Organisation – ISO 15189). Further studies are needed in order to address issues related to the impact of ART on epigenetic reprogramming of the early embryo. The legal landscape regarding assisted reproduction is evolving but still remains very heterogeneous and often contradictory. The lack of legal harmonisation and uneven access to infertility treatment and PGD/PGS fosters considerable cross-border reproductive care in Europe and beyond. The aim of this paper is to complement previous publications and

    Training systems for occupational physicians (OPs) have existed since the Industrial Safety and Health Act was enacted in 1972. However, it is necessary to enhance them because of changes in the business environment of Japanese corporations and working patterns have brought about new needs of occupational health (OH) activities. In this paper, OPs were classified into three categories; doctors who spend a part of working time on OH activities, i.e. "non-specialist OPs", doctors who engage in OH activities full-time, i.e. "specialists OPs", and doctors who manage corporate-wide occupational health programs or lead programs at OH service institutes, i.e. "lead OPs", and the status and the issues were reviewed. The major concern identified for each of the three categories in training were found to be quality management for non-specialist OPs, short supply for specialists OPs, and development of competencies such as leadership and management skills for lead OPs, respectively. Current efforts and ideas to improve the training systems were discussed.

    Retrograde amnesia following electroconvulsive therapy (ECT) is a major concern for both patients and clinicians. In contemporary ECT research, retrograde autobiographical amnesia (RAA) is commonly measured with instruments assessing autobiographical memory (AM) consistency over time. However, normal AM recall loses in consistency with the passage of time, and time has a differential effect on stability of personal memories. In addition, experiencing depression is associated with a decreased ability to recall specific AMs, and this difficulty may persist in the euthymic phase of recurrent depression. Despite these scientific facts, relatively few attempts have been made to accurately measure the specific effect of ECT on AM independent of both normal and mood-associated forgetting over time. This major gap in our knowledge prevents us at present from objectively quantifying the nature and extent of RAA associated with ECT. In turn, this hinders our identifying and implementing strategies for prevention or remediation of AM deficits. The present article aims to provide an up-to-date review and historical perspective of this major methodological conundrum for ECT research, highlight current issues in retrograde amnesia assessment following ECT, and propose directions for future studies. In conclusion, we suggest methods to reliably and specifically measure the extent and progression over time of ECT-associated RAA independently from persistent depressive symptoms' contribution and normal loss in AM consistency over time.

    We conducted a questionnaire survey regarding the current activities for protecting patients' privacy and the security of information systems (IS) related to the clinical laboratory departments of university hospitals, certified training facilities for clinical laboratories, and general hospitals in Yamaguchi Prefecture. The response rate was 47% from 215 medical institutions, including three commercial clinical laboratory centers. The results showed that there were some differences in management activities among facilities with respect to continuing education, the documentation or regulation of operational management for paper records, electronic information, remaining samples, genetic testing, and laboratory information for secondary use. They were suggested to be caused by differences in functions between university and general hospitals, differences in the scale of hospitals, or whether or not hospitals have received accreditation or ISO 15189. Regarding the IS, although the majority of facilities had sufficiently employed the access control to IS, there was some room for improvement in the management of special cases such as VIPs and patients with HIV infection. Furthermore, there were issues regarding the login method for computers shared by multiple staff, the showing of the names of personnel in charge of reports, and the risks associated with direct connections to systems and the Internet and the use of portable media such as USB memory sticks. These results indicated that further efforts are necessary for each facility to continue self-assessment and make improvements.

    Full Text Available Producer responsibility for wastes has been encouraged in Indonesia since 2008. The Ministry of Environment of the Republic of Indonesia also promoted the reduce, reuse, and recycle (3R concept using the community-based approach of waste banks integrated with the extended producer responsibility (EPR concept. However, related research and implementation are still limited. This study aims to identify the challenges of fulfilling producer responsibility in waste management and determine whether the integration concept could generate outcomes expected from the EPR concept. A semi-structured interview survey of several stakeholders from the government, industrial, and waste management sectors was conducted and the data generated was used to simulate an integration scheme using a system dynamics approach. Secondary data and information from Bandung municipality were used as input for the simulation. The interview survey found that the concerns and issues of fulfilling producer responsibility in waste management include lack of awareness, unavailability of clear guidelines, and the limited capacity of the current recycling sector. The results of the simulation suggested that if the integration scheme is applied, each business entity might bear the responsibility of IDR 29.4 million per year and 14.7 tons of waste per year for the scope of four sectors and IDR 34.1 million per year and 17 tons of waste per year for the scope of two sectors.

    Full Text Available Secondary organic aerosol (SOA accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes, climate and human health. The chemical and physical processes associated with SOA formation are complex and varied, and, despite considerable progress in recent years, a quantitative and predictive understanding of SOA formation does not exist and therefore represents a major research challenge in atmospheric science. This review begins with an update on the current state of knowledge on the global SOA budget and is followed by an overview of the atmospheric degradation mechanisms for SOA precursors, gas-particle partitioning theory and the analytical techniques used to determine the chemical composition of SOA. A survey of recent laboratory, field and modeling studies is also presented. The following topical and emerging issues are highlighted and discussed in detail: molecular characterization of biogenic SOA constituents, condensed phase reactions and oligomerization, the interaction of atmospheric organic components with sulfuric acid, the chemical and photochemical processing of organics in the atmospheric aqueous phase, aerosol formation from real plant emissions, interaction of atmospheric organic components with water, thermodynamics and mixtures in atmospheric models. Finally, the major challenges ahead in laboratory, field and modeling studies of SOA are discussed and recommendations for future research directions are proposed.

    Health care-associated infection is a leading cause of morbidity and mortality. Hand hygiene is widely regarded as an effective prevention strategy. Often, hand hygiene research is designed and conducted by health care practitioners who may lack formal training in research methods, particularly in the area of social science. In a research context, a construct is a concept that can be measured or observed in some way. A construct can be directly or indirectly measured. For example, height can be directly measured by centimeters, whereas depression can be indirectly measured by a scale of 20 items. Every construct needs to be operationalized by measure(s) to make it a variable. Hence, construct validity refers to the degree of fit between the construct of interest and its operational measure. However, issues with construct validity often weaken the translation from construct to measure(s). This article will (1) describe the common threats to construct validity pertaining to hand hygiene research, (2) identify practical limitations in current research design, and (3) provide recommendations to improve construct validity in future hand hygiene research. By understanding how construct validity may affect hand hygiene research design, there is great potential to improve the validity of future hand hygiene research findings.

    How has the interface between genetics and assisted reproduction technology (ART) evolved since 2005? The interface between ART and genetics has become more entwined as we increase our understanding about the genetics of infertility and we are able to perform more comprehensive genetic testing. In March 2005, a group of experts from the European Society of Human Genetics and European Society of Human Reproduction and Embryology met to discuss the interface between genetics and ART and published an extended background paper, recommendations and two Editorials. An interdisciplinary workshop was held, involving representatives of both professional societies and experts from the European Union Eurogentest2 Coordination Action Project. In March 2012, a group of experts from the European Society of Human Genetics, the European Society of Human Reproduction and Embryology and the EuroGentest2 Coordination Action Project met to discuss developments at the interface between clinical genetics and ART. As more genetic causes of reproductive failure are now recognized and an increasing number of patients undergo testing of their genome prior to conception, either in regular health care or in the context of direct-to-consumer testing, the need for genetic counselling and PGD may increase.

    Emerging countries will have to tackle different social and economic development challenges in the future, which translate nationally into the concepts of 'harmonious society' in China and 'inclusive growth' in India, and into the Brazilian slogan 'a wealthy country is a country without poverty'. Per capita (current US$), Brazil is more than two times richer than China, which in turn is three times richer than India. This graduation explains the variety of priorities of those countries: reducing inequalities and achieving the development processes in China and Brazil, alleviating poverty and enhancing energy access in India. Furthermore, these countries are increasingly linked internationally, along with the globalization process. Energy security is a key issue for China and India, while Brazil aims at playing a key role on future international energy markets. Emerging economies are progressively laying the foundations for low-carbon development strategies that will depend on their national contexts and priorities. Investments in building and transport infrastructures are increasingly important in all those countries, creating the conditions today for tomorrow's low-carbon economic development. China recently made important resolutions in the framework of its 12. Five-Year Plan, decoupling economic growth from GHG emissions. India has developed eight 'National Missions' on climate change and is now exploring future low-carbon strategies. And Brazil is affirming its position internationally, pushing for innovative 'green growth' concepts, within the framework of the Rio+20 Conference. All countries have already implemented several energy and climate policies and plan to develop them further, through innovative policy institutions and instruments. They are switching progressively from command- and-control to economic instruments. In particular, market-based mechanisms are increasingly used in all countries: mandatory pilot Emission Trading Systems (ETS) in China

  3. Bipolar disorder and complementary medicine: current evidence, safety issues, and clinical considerations.

    Bipolar disorder (BD) is a debilitating syndrome that is often undiagnosed and undertreated. Population surveys show that persons with BD often self-medicate with complementary and alternative medicine (CAM) or integrative therapies in spite of limited research evidence supporting their use. To date, no review has focused specifically on nonconventional treatments of BD. The study objectives were to present a review of nonconventional (complementary and integrative) interventions examined in clinical trials on BD, and to offer provisional guidelines for the judicious integrative use of CAM in the management of BD. PubMed, CINAHL,(®) Web of Science, and Cochrane Library databases were searched for human clinical trials in English during mid-2010 using Bipolar Disorder and CAM therapy and CAM medicine search terms. Effect sizes (Cohen's d) were also calculated where data were available. Several positive high-quality studies on nutrients in combination with conventional mood stabilizers and antipsychotic medications in BD depression were identified, while branched-chain amino acids and magnesium were effective (small studies) in attenuating mania in BD. In the treatment of bipolar depression, evidence was mixed regarding omega-3, while isolated studies provide provisional support for a multinutrient formula, n-acetylcysteine, and l-tryptophan. In one study, acupuncture was found to have favorable but nonsignificant effects on mania and depression outcomes. Current evidence supports the integrative treatment of BD using combinations of mood stabilizers and select nutrients. Other CAM or integrative modalities used to treat BD have not been adequately explored to date; however, some early findings are promising. Select CAM and integrative interventions add to established conventional treatment of BD and may be considered when formulating a treatment plan. It is hoped that the safety issues and clinical considerations addressed in this article may encourage the practice

  4. A discussion of current issues and concepts in the practice of skull-photo/craniofacial superimposition.

    2016-05-01

    A recent review paper on cranio-facial superimposition (CFS) stated that "there have been specific conceptual variances" from the original methods used in the practice of skull-photo superimposition, leading to poor results as far as accuracy is concerned. It was argued that the deviations in the practice of the technique have resulted in the reduced accuracies (for both failure to include and failure to exclude) that are noted in several recent studies. This paper aims to present the results from recent research to highlight the advancement of skull-photo/cranio-facial superimposition, and to discuss some of the issues raised regarding deviations from original techniques. The evolving methodology of CFS is clarified in context with the advancement of technology, forensic science and specifically within the field of forensic anthropology. Developments in the skull-photo/cranio-facial superimposition techniques have largely focused on testing reliability and accuracy objectively. Techniques now being employed by forensic anthropologists must conform to rigorous scientific testing and methodologies. Skull-photo/cranio-facial superimposition is constantly undergoing accuracy and repeatability testing which is in line with the principles of the scientific method and additionally allows for advancement in the field. Much of the research has indicated that CFS is useful in exclusion which is consistent with the concept of Popperian falsifiability - a hypothesis and experimental design which is falsifiable. As the hypothesis is disproved or falsified, another evolves to replace it and explain the new observations. Current and future studies employing different methods to test the accuracy and reliability of skull-photo/cranio-facial superimposition will enable researchers to establish the contribution the technique can have for identification purposes.

    Objective: This report summarizes data on traditional and nontraditional manifestations of primary hyperparathyroidism (PHPT) that have been published since the last International Workshop on PHPT. Participants: This subgroup was constituted by the Steering Committee to address key questions related to the presentation of PHPT. Consensus was established at a closed meeting of the Expert Panel that followed. Evidence: Data from the 5-year period between 2008 and 2013 were presented and discussed to determine whether they support changes in recommendations for surgery or nonsurgical follow-up. Consensus Process: Questions were developed by the International Task Force on PHPT. A comprehensive literature search for relevant studies was undertaken. After extensive review and discussion, the subgroup came to agreement on what changes in the recommendations for surgery or nonsurgical follow-up of asymptomatic PHPT should be made to the Expert Panel. Conclusions: 1) There are limited new data available on the natural history of asymptomatic PHPT. Although recognition of normocalcemic PHPT (normal serum calcium with elevated PTH concentrations; no secondary cause for hyperparathyroidism) is increasing, data on the clinical presentation and natural history of this phenotype are limited. 2) Although there are geographic differences in the predominant phenotypes of PHPT (symptomatic, asymptomatic, normocalcemic), they do not justify geography-specific management guidelines. 3) Recent data using newer, higher resolution imaging and analytic methods have revealed that in asymptomatic PHPT, both trabecular bone and cortical bone are affected. 4) Clinically silent nephrolithiasis and nephrocalcinosis can be detected by renal imaging and should be listed as a new criterion for surgery. 5) Current data do not support a cardiovascular evaluation or surgery for the purpose of improving cardiovascular markers, anatomical or functional abnormalities. 6) Some patients with mild PHPT

    Maren Borkert

    2006-05-01

    Full Text Available This article introduces contemporary migration research from the perspective of a cross-section of itinerant European academics at the early stages of their research career. Specifically, it examines self-reflexivity as an effective tool to support qualitative data analysis in light of the multiple dimensions of migration and ethnic research in Europe. As part of this reflexivity, the paper considers the complex relations and relationships that shape researcher-participant interaction. It shows how these are made even more intricate and confusing by research conducted outside ones home country and/ or with national communities to which one does not "naturally" belong. Over recent years, the European Commission has sought to foster inter-academic exchange, especially amongst new European researchers. Emphasis has been placed on the need to build up effective international and inter-disciplinary research networks but, we argue, very little attention has been directed towards how the processes of up-rooting and re-grouping facilitate and/ or restrict the research experience. Using self-reflexivity, and in light of the particular complexities of carrying out international migration research, the paper will review these issues and seek to increase our understanding of how young European academics become successful transnational researchers.

    incomplete data from the other two, US EPA/NCEA issued a document in December 1998 stating that the critical effects were hormone and histology data from the neurodevelopmental/behavioral toxicity study that had been performed in rats; an RfD was proposed based upon the observation of thyroid-follicular-cell hypertrophy in the 5-day-old pups (PND) of dams given perchlorate in drinking water at 0.1 mg/kg-day (the lowest dose tested) in this study. US EPA/NCEA also focused attention on a nonsignificant increase in motor activity observed in 14-day-old male pups in the same study at the same dose. In February 1999, a public workshop was convened at which an external peer-review panel determined that there was still insufficient data to support the development of a RfD. Additional studies were recommended. Since that time a clinical study revealed significant depression of thyroidal uptake of iodide in volunteers receiving potassium perchlorate at 10 mg/day for 14 days. Follow-up studies currently underway include a pathology working-group review of histology slides from the all of the previous studies, a motor activity study similar to the first behavioral study, an additional immunotoxicity study, male and female rat kinetic studies, a hormone interlaboratory study, and an effects study for thyroid and brain in developing rats. These studies are expected to be complete by mid-2000. A clinical study is planned to determine inhibition of iodide uptake and kinetic parameters in humans following 14-day perchlorate ingestion. The kinetics studies will provide data for developing physiologically based pharmacokinetic (PBPK) models for rats and humans needed to establish the RfD.

    This paper discusses some technical issues identified from the seismic hazard analyses for probabilistic safety assessment on the operating Korean nuclear power plants and the related activities to resolve the issues. Since there are no strong instrumental earthquake records in Korea, the seismic hazard analysis is mainly dependent on the historical earthquake records. Results of the past seismic hazard analyses show that there are many uncertainties in attenuation function and intensity level and that there is a need to improve statistical method. The identification of the activity of the Yangsan Fault, which is close to nuclear power plant sites, has been an important issue. But the issue has not been resolved yet in spite of much research works done. Recently, some capable faults were found in the offshore area of Gulupdo Island in the Yellow Sea. It is anticipated that the results of research on both the Yangsan Fault and reduction of uncertainty in seismic hazard analysis will have an significant influence on seismic design and safety assessment of nuclear power plants in the future.

    Highlights: • We present challenges in thermal hydraulic design of sodium cooled fast reactors. • We present roadmap of Indian fast reactor program and innovative design concepts. • Analysis methodology for thermal striping and thermal stratification are highlighted. • Design solutions for gas entrainment are presented. • Experimental approaches for normal and post accident decay heat removal are highlighted. - Abstract: Pool type sodium cooled fast reactors pose several design challenges and among them, certain thermal hydraulics and structural mechanics issues are special. High frequency temperature fluctuations due to thermal striping, thermal stratifications and sodium free level fluctuations at the liquid–cover gas interfaces are to be investigated carefully to eliminate high cycle thermal fatigue of structures. Solutions to address the core thermal hydraulics call for high power computing. Innovative concepts and methods are developed to carry out plant dynamics and safety studies. Particularly, extensive numerical and experimental simulation techniques are needed for understanding and solving the gas entrainment mechanisms and its effects on core safety. Though decay heat removal through natural convection is achievable in a pool type SFR, demonstration of design solutions conceived in the reactor and performance of diverse systems under all operating conditions, especially over prolonged station blackout situations needs advanced CFD computations and should be validated by relatively large scale simulated experiments. These issues are addressed in this paper under five broad topics: special thermal hydraulic issues to be addressed in SFR, thermal hydraulic design and analysis, plant dynamics studies, safety studies and evolving thermal hydraulic studies for the future FBRs. The 500 MWe Prototype Fast Breeder Reactor (PFBR) is taken as the reference design for addressing the issues. Indian fast reactor programme is highlighted in the introduction

    The authors comment on recent reviews of cardiovascular job strain research by P. L. Schnall and P. A. Landsbergis (1994), and by T. S. Kristensen (1995), which conclude that job strain as defined by the demand-control model (the combination of contributions of low job decision latitudes and high psychological job demands) is confirmed as a risk factor for cardiovascular mortality in a large majority of studies. Lack of social support at work appears to further increase risk. Several still-unresolved research questions are examined in light of recent studies: (a) methodological issues related to use of occupational aggregate estimations and occupational career aggregate assessments, use of standard scales for job analysis and recall bias issues in self-reporting; (b) confounding factors and differential strengths of association by subgroups in job strain-cardiovascular disease analyses with respect to social class, gender, and working hours; and (c) review of results of monitoring job strain-blood pressure associations and associated methodological issues.

    Research into post-wildfire effects began in the United States more than 70 years ago and only later extended to other parts of the world. Post-wildfire responses are typically transient, episodic, variable in space and time, dependent on thresholds, and involve multiple processes measured by different methods. These characteristics tend to hinder research progress, but the large empirical knowledge base amassed in different regions of the world suggests that it should now be possible to synthesize the data and make a substantial improvement in the understanding of post-wildfire runoff and erosion response. Thus, it is important to identify and prioritize the research issues related to post-wildfire runoff and erosion. Priority research issues are the need to: (1) organize and synthesize similarities and differences in post-wildfire responses between different fire-prone regions of the world in order to determine common patterns and generalities that can explain cause and effect relations; (2) identify and quantify functional relations between metrics of fire effects and soil hydraulic properties that will better represent the dynamic and transient conditions after a wildfire; (3) determine the interaction between burned landscapes and temporally and spatially variable meso-scale precipitation, which is often the primary driver of post-wildfire runoff and erosion responses; (4) determine functional relations between precipitation, basin morphology, runoff connectivity, contributing area, surface roughness, depression storage, and soil characteristics required to predict the timing, magnitudes, and duration of floods and debris flows from ungaged burned basins; and (5) develop standard measurement methods that will ensure the collection of uniform and comparable runoff and erosion data. Resolution of these issues will help to improve conceptual and computer models of post-wildfire runoff and erosion processes.

  13. Current status of environmental, health, and safety issues of lithium ion electric vehicle batteries

    1995-09-01

    The lithium ion system considered in this report uses lithium intercalation compounds as both positive and negative electrodes and has an organic liquid electrolyte. Oxides of nickel, cobalt, and manganese are used in the positive electrode, and carbon is used in the negative electrode. This report presents health and safety issues, environmental issues, and shipping requirements for lithium ion electric vehicle (EV) batteries. A lithium-based electrochemical system can, in theory, achieve higher energy density than systems using other elements. The lithium ion system is less reactive and more reliable than present lithium metal systems and has possible performance advantages over some lithium solid polymer electrolyte batteries. However, the possibility of electrolyte spills could be a disadvantage of a liquid electrolyte system compared to a solid electrolyte. The lithium ion system is a developing technology, so there is some uncertainty regarding which materials will be used in an EV-sized battery. This report reviews the materials presented in the open literature within the context of health and safety issues, considering intrinsic material hazards, mitigation of material hazards, and safety testing. Some possible lithium ion battery materials are toxic, carcinogenic, or could undergo chemical reactions that produce hazardous heat or gases. Toxic materials include lithium compounds, nickel compounds, arsenic compounds, and dimethoxyethane. Carcinogenic materials include nickel compounds, arsenic compounds, and (possibly) cobalt compounds, copper, and polypropylene. Lithiated negative electrode materials could be reactive. However, because information about the exact compounds that will be used in future batteries is proprietary, ongoing research will determine which specific hazards will apply.

    Abandonment issues in the oil and gas industry, such as well sites, batteries, gas plants, compressor stations, and pipelines, were discussed. Responsibilities of the Canadian Association of Petroleum Producers (CAPP) for informing the Canadian public about energy and environmental issues on behalf of the upstream petroleum industry were reviewed. Industry regulators and those who have jurisdiction over the abandonment of facilities were identified. In Alberta, the main agencies are the Alberta Energy and Utilities Board, Alberta Environmental Protection, and Alberta Food and Rural Development in addition to the National Energy Board and Indian Oil and Gas Canada. At the end of 1995, 160,000 wells had been drilled in Alberta of which 60,000 are still active, 35,000 are suspended and 70,000 wells have been abandoned. The industry-financed Orphan Well Program was established to provide funds for facility abandonment, decontamination and surface reclamation costs associated with orphaned facilities. CAPP agrees that operators of oil and gas facilities must be held responsible and accountable for the abandonment of their facilities. CAPP is looking for support from government to ensure that enforcement actions limit the number of orphan facilities. tabs., figs

    Extreme external events is emerged as significant risk contributor to the nuclear power plants after Fukushima Daiichi accident due to the catastrophic earthquake followed by great tsunami greater than a design basis. This accident shows that the extreme external events have the potential to simultaneously affect redundant and diverse safety systems and thereby induce common cause failure or common cause initiators. The probabilistic risk assessment methodology has been used for the risk assessment and safety improvement against the extreme natural hazards. The earthquake and tsunami hazard is an important issue for the nuclear industry in Korea. In this paper, the role and application of probabilistic safety assessment for the post Fukushima action will be introduced. For the evaluation of the extreme natural hazard, probabilistic seismic and tsunami hazard analysis is being performed for the safety enhancement. The research activity on the external event PSA and its interim results will be introduced with the issues to be solved in the future for the reliability enhancement of the risk analysis results.

    Malaysia considers the construction industry as one of the main contributors to its Gross Domestic Product (GDP). However, there are some unresolved issues arising from the ongoing and widespread adoption of the conventional method of construction such as the resultant fragmentation of the industry itself; delays in production and delivery time of unnecessary wastages and lack of sustainability practice. Malaysian Government has been continuously encouraging the industry to use, partly or if not wholly, the Industrialized Building System (IBS), which is considered to be an important part of sustainable construction initiative. IBS was introduced to Malaysia as the solution to issues related to dependencies of foreign workers, raising demand for affordable accommodations and improving image, quality and productivity of construction industry. However, the IBS adoption in Malaysia remains low. This paper presents the review of the current issues and barriers of IBS adoption in Malaysian construction industry.

The project is part of Penn State University's National Science Foundation (NSF) Targeted Math Science Partnership grant, with one goal of the grant to help current middle school teachers across Pennsylvania engage students with significant and complex questions of Earth science. The free Apple software iBooks Author was used to create an electronic book for the iPad, focusing on a variety of controversial issues impacting the hydrosphere. The iBook includes image slideshows, embedded videos, interactive images and quizzes, and critical thinking questions along Bloom's Taxonomic Scale of Learning Objectives. Outlined in the introductory iBook chapters are the Big Ideas of Earth System Science and an overview of Earth's spheres. Since the book targets the hydrosphere, each subsequent chapter focuses on specific water issues, including glacial melts, aquifer depletion, coastal oil pollution, marine debris, and fresh-water chemical contamination. Each chapter is presented in a case study format that highlights the history of the issue, the development and current status of the issue, and some solutions that have been generated. The next section includes critical thinking questions in an open-ended discussion format that focus on the Big Ideas, proposing solutions for rectifying the situation, and/or assignments specifically targeting an idea presented in the case study chapter. Short, comprehensive multiple-choice quizzes are also in each chapter. Throughout the iBook, students are free to watch videos, explore the content and form their own opinions. As a result, this iBook fulfills the grant objective by engaging teachers and students with an innovative technological presentation that incorporates Earth system science with current case studies regarding global water issues.

    Objectives The use of maternal and child health-related information is an issue faced by the "Healthy parents and children 21" campaign, a national campaign to improve the health standards of mothers and children in Japan. This study described the current situation and issues faced by municipalities across Japan that use this information.Methods Data across municipalities selected for the current survey of promoting the "Healthy parents and children 21" campaign in 2013 were analyzed in this study. First, we chose prefectures where collected and analyzed maternal and child health-related information was provided by the municipalities. Then, we divided the municipalities according to those prefectures where the municipalities regularly reported the maternal and child health-related information and those that did not report it regularly. Finally, the characteristics about maternal and child health in those municipalities were investigated.Results Of the 47 prefectures analyzed, 35 prefectures (74.5%) collected and analyzed maternal and child health-related information provided by the municipalities. The 35 prefectures included 1,242 municipalities, of which 700 (56.4%) regularly reported maternal and child health-related information, and 542 (43.6%) did not report it regularly. The proportion of municipalities, where information about smoking during pregnancy, immunization, or low birth weight in infants was positively used, was significantly lower among municipalities that did not regularly report maternal and child health-related information than among those that regularly reported it (P<0.001). The proportion of municipalities that coordinated projects on prevention of child abuse or low birth weight in infants with the prefectures was significantly lower among municipalities that did not regularly report maternal and child health-related information than among those that regularly reported it.Conclusion Among municipalities that did not regularly report

    2011-11-01

    This article reviews family nursing research published from 1996 to 2011. This is a follow-up to a review published in the Journal of Family Nursing in 1995. Findings from the first review are compared with this one, trends in family nursing scholarship are identified, and predictions and suggestions for future directions are offered. The latest generation of family nursing scholarship is conceptually and methodologically sound, and there is evidence of more multidisciplinary and interdisciplinary research conducted by family nursing researchers. Scholars are paying more attention to issues of diversity and family context at present than in the past, although there are still aspects of diversity that need more attention. Strong research programs in family nursing exist worldwide; an international synergism has helped promote rapid expansion of family nursing research and theory development. A vigorous movement to promote research to practice initiatives and greater attention to family interventions are exciting developments.

    2015-01-01

    Noninvasive prenatal genetic testing (NIPT) for chromosomal aneuploidy involving the analysis of cell-free fetal DNA became commercially available in 2011. The low false-positive rate of NIPT, which reduces unnecessary prenatal invasive diagnostic procedures, has led to broad clinician and patient adoption. We discuss the ethical, legal, and social issues raised by rapid and global dissemination of NIPT. The number of women using NIPT is anticipated to expand, and the number of conditions being tested for will continue to increase as well, raising concerns about the routinization of testing and negative impacts on informed decision making. Ensuring that accurate and balanced information is available to all pregnant women and that access to NIPT is equitable will require policy guidance from regulators, professional societies, and payers. Empirical evidence about stakeholders' perspectives and experiences will continue to be essential in guiding policy development so that advances in NIPT can be used effectively and appropriately to improve prenatal care.

    Planning a new health sciences library at the beginning of the twenty-first century is a tremendous challenge. Technology has radically changed the way libraries function in an academic environment and the services they provide. Some individuals question whether the library as place will continue to exist as information becomes increasingly available electronically. To understand how libraries resolve programming and building design issues, visits were made to three academic health sciences libraries that have had significant renovation or completed new construction. The information gathered will be valuable for planning a new library for the University of Colorado Health Sciences Center and may assist other health sciences librarians as they plan future library buildings.

Introducing new genes to the recipient organism enables to give them new features, absent before. Continuous increase in the area of the biotech crops triggers continuous discussion about safety of genetically modified (GM) crops, including food and feed derived from them. Important issue connected with cultivation of genetically modified crops is a horizontal gene transfer and a bacterial antibiotic resistance. Discussion about safety of GM crops concerns also food allergies caused by eating genetically modified food. The problem of genetic modifications of GM crops used for livestock feeding is widely discussed, taking into account Polish feed law.

    Action to improve women's occupational health has been slowed by a notion that women's jobs are safe and that any health problems identified among women workers can be attributed to unfitness for the job or unnecessary complaining. With increasing numbers of women in the labor force, the effects of work on women's health have recently started to interest health care providers, health and safety representatives and researchers. We begin our summary of their discoveries with a discussion of women's place in the workplace and its implications for occupational health, followed by a brief review of some gender-insensitive data-gathering techniques. We have then chosen to concentrate on the following four areas: methods and data collection; directing attention to women's occupational health problems; musculoskeletal disease; mental and emotional stress. We conclude by pointing out some neglected occupational groups and health issues.

    Cancer is a major threat to public health in the 21st century because it is one of the leading causes of death worldwide. The mechanisms of carcinogenesis, cancer invasion, and metastasis remain unclear. Thus, the development of a novel approach for cancer detection is urgent, and real-time monitoring is crucial in revealing its underlying biological mechanisms. With the optical and chemical advantages of quantum dots (QDs), QD-based nanotechnology is helpful in constructing a biomedical imaging platform for cancer behavior study. This review mainly focuses on the application of QD-based nanotechnology in cancer cell imaging and tumor microenvironment studies both in vivo and in vitro, as well as the remaining issues and future perspectives

    1995-02-01

    Lithium solid polymer electrolyte (SPE) batteries are being investigated by researchers worldwide as a possible energy source for future electric vehicles (EVs). One of the main reasons for interest in lithium SPE battery systems is the potential safety features they offer as compared to lithium battery systems using inorganic and organic liquid electrolytes. However, the development of lithium SPE batteries is still in its infancy, and the technology is not envisioned to be ready for commercialization for several years. Because the research and development (R&D) of lithium SPE battery technology is of a highly competitive nature, with many companies both in the United States and abroad pursuing R&D efforts, much of the information concerning specific developments of lithium SPE battery technology is proprietary. This report is based on information available only through the open literature (i.e., information available through library searches). Furthermore, whereas R&D activities for lithium SPE cells have focused on a number of different chemistries, for both electrodes and electrolytes, this report examines the general environmental, health, and safety (EH&S) issues common to many lithium SPE chemistries. However, EH&S issues for specific lithium SPE cell chemistries are discussed when sufficient information exists. Although lithium batteries that do not have a SPE are also being considered for EV applications, this report focuses only on those lithium battery technologies that utilize the SPE technology. The lithium SPE battery technologies considered in this report may contain metallic lithium or nonmetallic lithium compounds (e.g., lithium intercalated carbons) in the negative electrode.

  16. Fundamental Issues in Manufacturing Photovoltaic Modules Beyond the Current Generation of Materials

    Directory of Open Access Journals (Sweden)

    G. F. Alapatt

    2012-01-01

    Full Text Available Many methods to improve the solar cell’s efficiency beyond current generation of bulk and thin film of photovoltaic (PV devices have been reported during the last five decades. Concepts such as multiple exciton generations (MEG, carrier multiplication (CM, hot carrier extraction, and intermediate band solar cells have fundamental flaws, and there is no experimental evidence of fabricating practical higher efficiency solar cells based on the proposed concepts. To take advantages of quantum features of nanostructures for higher performance PV devices, self-assembly-based bottom-up processing techniques are not suitable for manufacturing due to inherent problems of variability, defects, reliability, and yield. For processing nanostructures, new techniques need to be invented with the features of critical dimensional control, structural homogeneity, and lower cost of ownership as compared to the processing tools used in current generations of bulk and thin-film solar cells.

    Kandlikar, Satish G.; Lu Zijie

    2009-01-01

    Understanding the thermal effects is critical in optimizing the performance and durability of proton exchange membrane fuel cells (PEMFCs). A PEMFC produces a similar amount of waste heat to its electric power output and tolerates only a small deviation in temperature from its design point. The balance between the heat production and its removal determines the operating temperature of a PEMFC. These stringent thermal requirements present a significant heat transfer challenge. In this work, the fundamental heat transfer mechanisms at PEMFC component level (including polymer electrolyte, catalyst layers, gas diffusion media and bipolar plates) are briefly reviewed. The current status of PEMFC cooling technology is also reviewed and research needs are identified

    1998-08-01

    During the last 10 years, at-home tooth bleaching using peroxide-containing agents has quickly become well accepted. It is one of the most popular cosmetic dental procedures for whitening teeth. Although there are few disputes regarding their efficacy, concerns and debates have continued regarding the safety of peroxide-containing tooth bleaching agents. Potential carcinogenicity and genotoxicity of the peroxides used in bleaching agents are the two most persistent and controversial issues. This article reviews and discusses available information on carcinogenicity and genotoxicity of hydrogen peroxide and the potential risks associated with the use of peroxide-containing bleaching agents. Clinical studies reported after the 1996 international symposium on responses of oral tissues to peroxide-containing bleaching agents are also reviewed. Overall evidence supports the conclusion that the proper use of peroxide-containing at-home tooth bleaching agents is safe. However, potential adverse effects may occur in inappropriate applications, abuses, or the use of inappropriate products. At-home tooth bleaching should be monitored by dental professionals to maximize the benefits while minimizing potential risks.

  5. Crime Prevention and Criminological Theories: Three Issues for the Current Time

    2014-06-01

    Full Text Available Any crime prevention strategy implies, explicitly or implicitly, the question about what crime is, the causes of it and how to avert it. In this paper we will focus on set, thru criminological theories, the “concepts” that have been renewal to build different answers to such questions, particularly on crime prevention’s policies in contemporary Argentina. We suggest three axes: first, the criminal positivist sociology of Enrico Ferri, particularly his idea of “ penalties equivalent,”; second, the discussion about crime prevention in the “Chicago School”, specially on Thrasher Frederich’s work; and finally, “multi-agency intervention” idea of the left realist criminology, especially Jock Young, Roger Matthews and John Lea. Such productions have in common the fact that the three have specifically discussed the issue of “crime prevention” on their work. The selection criteria and comparison axis emerges from a broader investigation, which aimed to analyze the modes of way that the association between crime and living conditions is addressed on the social crime prevention policies in Argentina, during the first decade of the new century. Three comparatives dimensions were analyzed: the way social policies appears on crime prevention strategies; the ways the target populations are delimited; and last, the ways the intervention territories are defined, building an specific idea of territory.

    In the present study there are discussed modern methods of the tension free hernioplastics, the complications associated with them and technical difficulties, up-to-date views and the perspectives of the issue development in terms of avoiding infectious complications, positioning of implants and their fixation. Hernia is one of the widespread surgical pathologies as it is found in 4% of the population and its share among the inpatient surgical diseases is about 18-30%. Consequently annually up to 20-21 mln hernioplasties are carried out worldwide. Despite of many years of experience in the field of hernia surgical treatment there still exist many unsolved problems such as safe closure of defects of abdominal cavity wall. Up to 200 methods of hernioplastics, various implantations and application of synthetic materials refer to lack of the optimal surgical strategy. In modern herniology priorities are given to tension free plastics. The merge of the synthetic implants and "tension free hernioplastics" concepts enabled sharp reduction of the side effects list, making it possible to perform successful surgeries in that contingent whose treatment by the method of tissue-plasty was related with high risk of lethality. Large scale introduction of tension free hernioplastics caused intensification of the associated problems such as migration, dissection and shortening of the net.

    Safety is important to every one working in the various organizations. They want to be safe when coming to work, at the time of work and going back to home. The ultimate aim of every worker is to work for the needs/money and or satisfaction where these would get prioritized according to the individuals. People don't want accidents to happen. People don't want to get themselves injured nor their colleagues. People would like and love to work in a company which cares for them and keeps them safe. Having said this then what makes them meet with or see an accident in the wind farm? Yes it is the unsafe act and unsafe condition which causes an accident in the wind farm. The present study put forward the factors /issues that influence people behaviors as part of weakening the safety culture to perform an unsafe act or to ignore and work in an unsafe condition.

    1994-11-01

    Much of the current focus on indoor environmental quality and ventilation in US office buildings is a response to sick building syndrome and occupant complaints about building-related health symptoms, poor indoor air quality, and thermal discomfort. The authors know that serious ``sick-building`` problems occur in a significant number of US office buildings and that a significant proportion of the occupants in many normal (non-sick) buildings report building-related health symptoms. Concerns about the health effects of environmental tobacco smoke have also focused attention on the indoor environment. The major responses of industry and governments, underway at the present time, are to restrict smoking in offices, to attempt to reduce the emissions of indoor pollutants, and to improve the operation of heating, ventilating and air conditioning (HVAC) systems. Better air filtration, improved HVAC commissioning and maintenance, and increased provisions for individual control of HVAC are some of the improvements in HVAC that are currently being, evaluated. In the future, the potential for improved productivity and reduced airborne transmission of infectious disease may become the major driving force for improved indoor environments.

    To identify and explore features of ethical issues that senior clinicians faced as deployed medical directors (DMDs) to the British Field Hospital in Afghanistan as well as to determine the ethical training requirements for future deployments. A qualitative study in two phases conducted from November 2014 to June 2015. Phase 1 analysed 60 vignettes of cases that had generated ethical dilemmas for DMDs. Phase 2 included focus groups and an interview with 13 DMDs. Phase 1 identified working with limited resources, dual conflict of meeting both clinical and military obligations and consent of children as the most prevalent ethical challenges. Themes found in Phase 2 included sharing clinical responsibilities with clinicians from other countries and not knowing team members' ways of working, in addition to the themes from Phase 1. This study has drawn together examples of scenarios to form a repository that will aid future training. Recommendations included undertaking ethics training together as a team before, during and after deployment which must include all nationalities who are assigned to the same operational tour, so that different ethical views can be explored beforehand.

    activities. The previously sparsely populated SJV had quickly developed an even more severe ozone problem than previous years. From 1990 to 2010, the SFBA population expanded to inland locations and then even further into the sheltered SJV. SFBA emissions for ROG and NOx were decreased around 40% and 15%, respectively during this period. High ozone levels became rather infrequent for coastal SFBA locations. During the same period, the SJV population continued to expand rapidly while emissions decreased, especially for ROG. Peak ozone levels remained around 100 ppb and shifted to locations downwind of Fresno and Bakersfield. Central California has experienced perhaps the most dramatic population growth and shifts in the United States during the contemporary economic era. These changes in population have led to some of the most difficult air quality management problems faced by regulators in the United States. Lessons learned from central California highlight the potential benefits of acting early and also the necessity for a long-term, flexible approach using sustained regulations to accompany population changes.

    Thermal gasification at large scale for cogeneration of power and heat and/or production of fuels and materials is a main pathway for a sustainable deployment of biomass resources. However, so far no such full scale production exists and biomass gasification projects remain at the pilot or demonstration scale. This report focuses on the key critical technology challenges for the large-scale deployment of the following biomass-based gasification concepts: Direct Fluidized Bed Gasification (FBG), Entrained Flow Gasification (EFG) and indirect Dual Fluidized Bed Gasification (DFBG). The main content in this report is based on responses from a number of experts in biomass gasification obtained from a questionnaire. The survey was composed of a number of more or less specific questions on technical barriers as to the three gasification concepts considered. For formalising the questionnaire, the concept of Technology Readiness Level (TRL 1-9) was used for grading the level of technical maturity of the different sub-processes within the three generic biomass gasification technologies. For direct fluidized bed gasification (FBG) it is mentioned that the technology is already available at commercial scale as air-blown technology and thus that air-blown FBG gasification may be reckoned a mature technology. The remaining technical challenge is the conversion to operation on oxygen with the final goal of producing chemicals or transport fuels. Tar reduction, in particular, and gas cleaning and upgrading in general are by far the most frequently named technical issues considered problematic. Other important aspects are problems that may occur when operating on low-grade fuels - i.e. low-cost fuels. These problems include bed agglomeration/ash sintering as well as alkali fouling. Even the preparation and feeding of these low-grade fuels tend to be problematic and require further development to be used on a commercial scale. Furthermore, efficient char conversion is mentioned by

    Full Text Available The consumption of psychoactive substances has followed Humanity since the primordial of the civilization, not only by their medicinal proprieties as well as for religious and recreational purposes, however, its usage creates dependence and, subsequently, illicit traffic. Since the beginning of the previous century, many nations and international organisms have worked, without success, in the development of elimination strategies to this problem. Part of this failure is due to the current legal forms, because, when a new psychoactive substance is created, it occupies a legal void, in which its’ distribution and consumption are free, being recurrent updates to the legislation needed. An example of this situation was the one verified in the establishments commonly called smartshops. We purpose to compile the psychoactive substances’ legislation, analyse its’, advantages and disadvantages and to suggest a new legal form, based in new scientific facts, that allows to contour this situation.

    Greydanus, Donald E; Greydanus, Megan M

    2012-01-01

    The Internet has revolutionized education and social communication in the 21st century. This article reviews the growing literature identifying a number of adolescents and young adults with a pathologically excessive Internet use leading to many potential consequences. Current research dilemmas in this area include that Internet addiction is a broad topic with no standard definition and no standard measurement tools. Management of youth with identified problematic Internet use or misuse centers on behavioral therapy and treatment of comorbidities. Pharmacologic approaches are limited at this time but are undergoing research, such as use of opioid antagonists and antidepressants in adults with pathological gambling. Efforts should be expanded on not only the education of all adolescents regarding the benefits but also the potential negative consequences of Internet use. It is vital that we do this for Generation Z, whereas Generation ALPHA will soon benefit or suffer from our efforts in this regard today.

    BENIPA (Bentonite Barriers in Integrated Performance Assessment) is a research project, within the Fifth Framework Programme of the European Union, which was started on September 2000 and is has a duration of 36 months. The overall objective of BENIPA is to assess the state of the art in the treatment of bentonite barriers in Integrated Performance Assessment, evaluating the capacity and consistency of methods and data available to convincingly justify the capacity of bentonite to perform their assigned safety functions. During the first part of the project different bentonite barrier concepts have been reviewed and four reference cases have been defined for the modelling work in the project. FEP's Databases have been created and the scientific and technical bases for the analysis of bentonite barriers have been reviewed. In the second part of the project. as a step previous to modelling, an analysis of models for the mechanical, hydrological, thermal and chemical conditions is carried out, along with a review of the needs in input data. In BENIPA, calculations at process and integrated level are currently being performed among different codes to check consistency and sufficiency or complementarity for fulfilling the needs of performance assessment. However, since it is too early to present some of the results or even the individual contributions of the partners, the modelling and calculations being currently carried out by ENRESA will be advanced, just as a representative example of the work going on. This paper summarises the work already done in BENIPA and provides with illustrations of the modelling work consisting of the approach followed by ENRESA in applying three codes: CODE-BRIGHT, CORE 2D and GOLDSIM. The processes considered, simplifications adopted, limitations imposed and preliminary findings of the work are mentioned along. (author)

    Various kinds of radioactive waste are generated from nuclear power and fuel cycle facilities. These materials have to be treated, stored and eventually sent to a repository site. Transport of wastes between these various stages is crucial for the sustainable utilization of nuclear energy. The IAEA Regulations for the Safe Transport of Radioactive Material (SSR-6) have, for many decades, provided a safe and efficient framework for radioactive materials transport and continue to do so. However, some shippers have experienced that in the transport of certain specific radioactive wastes, difficulties can be encountered. For example, some materials produced in the decommissioning of nuclear facilities are unique in terms of composition or size and can be difficult to characterize as surface contaminated objects (SCO) or homogeneous. One way WNTI (World Nuclear Transport Institute) helps develop transport methodologies is through the use of Industry Working Groups, bringing together WNTI members with common interests, issues and experiences. The Back-End Transport Industry Working Group focuses on the following issues currently. - Characterization of Waste: techniques and methods to classify wastes - Large Objects: slightly contaminated large objects (ex. spent steam generators) transport - Dual Use Casks: transportable storage casks for spent nuclear fuels, including the very long term storage of spent fuel - Fissile Exceptions: new fissile exceptions provisions of revised TS-R-1 (SSR-6) The paper gives a broad overview of current issues for the packaging and transport of radioactive wastes and the associated work of the WNTI.

Termin ten, początkowo uważany za stan przejściowy pomiędzy prawidłowym funkcjonowaniem poznawczym a objawami choroby Alzheimera (Alzheimer’s disease, AD, obecnie oznacza heterogenną grupę widocznych i obiektywnych deficytów kognitywnych u pacjentów bez rozpoznanego otępienia. Deficyty te, choć zauważalne zarówno dla osób nimi dotkniętych, jak i ich otoczenia, są na tyle nieznaczne, że nie wpływają na podstawowe czynności życia codziennego i zdolność do samodzielnej egzystencji. Rozpowszechnienie MCI szacuje się na 15 – 30% wśród osób powyżej 60 roku życia; rośnie ono wraz z wiekiem. Łagodnym zaburzeniom poznawczym – zwłaszcza ich postaci amnestycznej - przypisuje się podwyższone ryzyko rozwinięcia się otępienia, wynoszące 10 – 15% rocznie (przy 1 – 2% dla populacji ogólnej. Z tego powodu identyfikacja osób z MCI jest obecnie najważniejszą strategią opóźniania postępu otępień i zapobiegania im.   Słowa kluczowe: łagodne zaburzenia poznawcze, funkcjonowanie poznawcze, wiek podeszły, otępienie       Summary The article describes current state of knowledge on Mild Cognitive Impairment (MCI. The term, initially considered a transitional state between normal cognitive aging and mild Alzheimer’s disease (AD, currently covers heterogenous group of noticeable and objective cognitive deficits in patients without the diagnosis of dementia. These deficits, although apparent for both afflicted persons and their environment, do not interfere substantially with basic activities of daily living nor result in inability to live independently. The prevalence of MCI is estimated between 15 and 30% in individuals over 60 years old.

    2013-01-01

    Hawaii is a pioneer in the use of phytosanitary irradiation. Irradiation is an approved treatment to control quarantine insect pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping tropical fruits and vegetables to the US mainland using irradiation since 2000. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5,500 tonnes). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) has accelerated commodity export approvals and facilitated adoption by foreign trading partners. Current impediments to wider adoption include the labeling requirement, the 1 kGy limit for fresh horticultural products, and non-acceptance of phytosanitary irradiation in Japan and the European Union. USDA Animal and Plant Health Inspection Service (APHIS) has restricted the use of modified atmosphere packaging (MAP) for irradiated fresh fruits exported to the US due to possible increased radio-tolerance in the target insects. Data are presented for response of melon fly in papaya to several types of MAP with radiation treatment at 45-65 Gy. Low oxygen atmospheres can increase insect radio-tolerance, but the effect is dependent on oxygen concentration and radiation dose. (author)

    Full Text Available In the middle of the last century, mites moved into the focus of attention as pests relevantto agriculture, forestry and landscape horticulture, presumably in direct reactionto the “green revolution” that involved plant cultivation in large-plot monocropping systems,improved methods of cultivation, selection of high-yielding cultivars and intensifieduse of pesticides and mineral fertilizers. Agroecosystems in which phytophagous miteshave become harmful organisms are primarily orchards, vineyards, greenhouses, urbangreeneries, plant nurseries and stored plant products, as well as annual field crops to asomewhat lesser degree. Phytophagous mite species belong to a variety of spider mites(Tetranychidae, false spider mites (Tenuipalpidae, gall and rust mites (Eriophyoidae, tarsonemidmites (Tarsonemidae and acarid mites (Acaridae. Most of these harmful speciesare widespread, some of them having more economic impact than others and being moredetrimental as depending on various specificities of each outdoor agroecosystem in anyparticular climatic region.The first segment of this overview focuses on the most significant mite pests ofagroecosystemsand urban horticultural areas in European countries, our own region andin Serbia today, primarily on species that have caused problems in recent years regardingplant production, and it also discusses various molecular methods available for investigatingdifferent aspects of the biology of phytophagous mites.

    Full Text Available ABSTRACT Post-polio syndrome (PPS is a condition that affects polio survivors years after recovery from an initial acute attack of the poliomyelitis virus. Most often, polio survivors experience a gradual new weakening in muscles that were previously affected by the polio infection. The actual incidence of cardiovascular diseases (CVDs in individuals suffering from PPS is not known. However, there is a reason to suspect that individuals with PPS might be at increased risk. Method A search for papers was made in the databases Bireme, Scielo and Pubmed with the following keywords: post polio syndrome, cardiorespiratory and rehabilitation in English, French and Spanish languages. Although we targeted only seek current studies on the topic in question, only the relevant (double-blind, randomized-controlled and consensus articles were considered. Results and Discussion Certain features of PPS such as generalized fatigue, generalized and specific muscle weakness, joint and/or muscle pain may result in physical inactivity deconditioning obesity and dyslipidemia. Respiratory difficulties are common and may result in hypoxemia. Conclusion Only when evaluated and treated promptly, somE patients can obtain the full benefits of the use of respiratory muscles aids as far as quality of life is concerned.

    Full Text Available The importance attributed to the territorial dimension of the European Union cohesion policy steadily influences its successive reforms and adaptations, while in recent years there has been an evolution in the way this particular dimension of cohesion policy is perceived. Important evidence for this is the way in which the Community Strategic Guidelines on cohesion 2007-13 take account of the territorial dimension of cohesion policy. This paper discusses the territorial approach to cohesion policy in relation to both policy and practice. Specifically, it examines the territorial dimension of regional development planning in Greece as it has emerged in the relevant official documents, namely the successive three Community Support Frameworks since 1989 and the National Strategic Reference Framework for the current 2007-13 period. The territorial dimension of the organization of the planning system is also considered in an effort to understand limitations and prospects, in light of the importance of the territorial approach to cohesion policy post-2013.

    Full Text Available In this article, we first discuss the inclusion of idioms in the latest printed editions of monolingual learner’s dictionaries; we then consider and evaluate the success of look-up operations in connection with the recognition of the correct part of speech. The central part of the article discusses and justifies the macro- and microstructural treatment of multi-word lexical items. Finally, we address the issue of including idioms in the microstructure as special senses of the lemma, as usage examples and/or in the idioms section. The inclusion and treatment of multi-word lexical items depends on the needs of potential dictionary users. Lexicographers should therefore strive to adopt a pragmatic approach that would help the user to locate a multi-word lexical item with minimal effort. When compiling a bilingual dictionary, contrastive differences between source and target languages should also be taken into consideration. http://dx.doi.org/10.5128/ERYa7.15

    Clostridium difficile infection (CDI) is the most common cause of infectious diarrhea in healthcare settings. Along with antimicrobial exposure, advanced age has been shown to be a significant risk factor for the development and recurrence of, and mortality from, CDI. The substantial burden of CDI in the elderly may be related to frequent healthcare exposure, the necessity for more medications, altered intestinal microbiota, and complicated comorbidities. A diagnosis of CDI is based on evidence of toxin, or the C. difficile organism itself, in a stool sample in the presence of clinical signs and symptoms. Only symptomatic patients should be tested for CDI, and routine surveillance or repeat testing on asymptomatic patients as a test of cure is discouraged. Antibiotic discontinuation alone can improve or resolve CDI in some patients, and concomitant use of antibiotics is associated with decreased response to CDI treatment. Metronidazole, vancomycin, and fidaxomicin are the therapeutic agents currently available for CDI, with the selection of these agents being based on disease severity, history of recurrence, and cost. The recurrence rate after initial treatment is 20-30%. The first recurrence can be treated with the same therapeutic agent and, for subsequent recurrences, vancomycin in a tapered and/or pulsed regimen is recommended. Fecal microbiota transplantation has shown remarkable effectiveness for recurrent anti-refractory CDI, although caution is advised in treating immunocompromised hosts and those with toxic megacolon. C. difficile can be transmitted directly and indirectly via contact with patients or their environment; therefore, isolation precautions should be initiated at the first suspicion of CDI. C. difficile spores can survive for a long time on environmental surfaces, and the patient's room and all equipment used in the room should be disinfected. In order to manage CDI in the elderly, timely diagnosis, appropriate treatment based on severity of

  8. Current Issues in Finite-T Density-Functional Theory and Warm-Correlated Matter †

    M. W. C. Dharma-wardana

    2016-03-01

    Full Text Available Finite-temperature density functional theory (DFT has become of topical interest, partly due to the increasing ability to create novel states of warm-correlated matter (WCM.Warm-dense matter (WDM, ultra-fast matter (UFM, and high-energy density matter (HEDM may all be regarded as subclasses of WCM. Strong electron-electron, ion-ion and electron-ion correlation effects and partial degeneracies are found in these systems where the electron temperature Te is comparable to the electron Fermi energy EF. Thus, many electrons are in continuum states which are partially occupied. The ion subsystem may be solid, liquid or plasma, with many states of ionization with ionic charge Zj. Quasi-equilibria with the ion temperature Ti ≠ Te are common. The ion subsystem in WCM can no longer be treated as a passive “external potential”, as is customary in T = 0 DFT dominated by solid-state theory or quantum chemistry. Many basic questions arise in trying to implement DFT for WCM. Hohenberg-Kohn-Mermin theory can be adapted for treating these systems if suitable finite-T exchange-correlation (XC functionals can be constructed. They are functionals of both the one-body electron density ne and the one-body ion densities ρj. Here, j counts many species of nuclei or charge states. A method of approximately but accurately mapping the quantum electrons to a classical Coulomb gas enables one to treat electron-ion systems entirely classically at any temperature and arbitrary spin polarization, using exchange-correlation effects calculated in situ, directly from the pair-distribution functions. This eliminates the need for any XC-functionals. This classical map has been used to calculate the equation of state of WDM systems, and construct a finite-T XC functional that is found to be in close agreement with recent quantum path-integral simulation data. In this review, current developments and concerns in finite-T DFT, especially in the context of non-relativistic warm

    The purpose of this study was to describe the practice of 796 ostomy nurses in North America in 2014 related to peristomal skin issues. Descriptive study. Participants were 796 wound, ostomy, and continence (WOC) and enterostomal therapy (ET) nurses currently practicing in the United States or Canada and caring for patients with ostomies. The collection of data occurred in conjunction with an educational program on peristomal skin complications and practice issues and solicited the participant's perception on the incidence and frequency of peristomal skin issues as well as on practice patterns. Participants attended an educational program. They were also asked to anonymously respond to multiple-choice questions on ostomy care management via an audience response system followed by discussion of each item and their responses. This descriptive study reports on the answers to the questions as well as the pertinent discussion points. Participants estimated that approximately 77.70% of their patients developed peristomal skin issues. The most commonly encountered problem was irritant contact dermatitis (peristomal moisture-associated skin damage). Contributing factors were inappropriate use of a pouching system owing to lack of follow-up after hospital discharge. Reported interventions for the prevention and management of peristomal skin issues included preoperative stoma site marking, use of a convex pouching system, and barrier rings. However, subsequent discussion revealed that the frequency of use of these products varied considerably. Participants identified shortened hospital stays, absence of preoperative stoma marking, and limited outpatient follow-up as contributing to development of peristomal skin problems. WOC and ET nurses estimate that more than three-quarters of persons living with an ostomy develop peristomal skin problems. Multiple interventions for managing these problems were identified, but some variability in management approaches emerged.

  10. Seismic Hazard Assessment and Uncertainties Treatment: Discussion on the current French regulation, practices and open issues

    Nuclear Safety Authority. These studies performed by nuclear operators, leading to propose a 'Hard Core' of materials and organizational arrangements to ensure the control of crucial safety functions in extreme situations. The difficulties inherent in the definition of 'extreme situation' in a moderate seismically country as the French metropolitan area will be illustrated and discussed. This presentation gives the current practice of seismic risk management in France for nuclear safety. The regulation is composed by two coherent and complementary references the RFS 2001-01 and the Guide ASN/2/01. We point out the key steps of the seismic hazard assessment following the RFS 2001-01 methodology which is scenario based. We particularly highlight the sensitivity and the influences of seismic parameters choices in their uncertainty domains and their impact on the final hazard. The Tohoku 2011 mega-quake and the Fukushima associated accident resulted in the Complementary Safety Studies in the Nuclear field. The review of the French complementary studies by the ENSREG made the recommendation to complete the scenario based approach by a probabilistic hazard assessment. The presentation then exhibits the specificities and common aspects of a PSHA and DSHA. We underline that these two approaches are strictly founded on common databases and knowledge level: The epistemic uncertainties can be accounted by both PSHA and DSHA through logic trees (see [37] for DSHA). However they clearly differ by two points: - the PSHA accounts for the whole seismic catalogue with its occurrence rate, where the DSHA selects specific scenarios with consideration of occurrence level, - the aleatory variability is differently treated in scenario approach and in probabilistic approach. Finally, performing probabilistic seismic hazard assessment requires defining crucial parameters (i) the safety level target which corresponds a return period value of the hazard curve and (ii) its confidence level.

    Final Report Abstract for DE-FG02-99ER4110, May 15, 2011- October 15, 2014 There is a synergy between the fields of Beam Dynamics (BD) in modern particle accelerators and Applied Mathematics (AMa). We have formulated significant problems in BD and have developed and applied tools within the contexts of dynamical systems, topological methods, numerical analysis and scientific computing, probability and stochastic processes, and mathematical statistics. We summarize the three main areas of our AMa work since 2011. First, we continued our study of Vlasov-Maxwell systems. Previously, we developed a state of the art algorithm and code (VM3@A) to calculate coherent synchrotron radiation in single pass systems. In this cycle we carefully analyzed the major expense, namely the integral-over-history (IOH), and developed two approaches to speed up integration. The first strategy uses a representation of the Bessel function J0 in terms of exponentials. The second relies on “local sequences” developed recently for radiation boundary conditions, which are used to reduce computational domains. Although motivated by practicality, both strategies involve interesting and rather deep analysis and approximation theory. As an alternative to VM3@A, we are integrating Maxwell’s equations by a time-stepping method, bypass- ing the IOH, using a Discontinuous Galerkin (DG) method. DG is a generalization of Finite Element and Finite Volume methods. It is spectrally convergent, unlike the commonly used Finite Difference methods, and can handle complicated vacuum chamber geometries. We have applied this in several contexts and have obtained very nice results including an explanation of an experiment at the Canadian Light Source, where the geometry is quite complex. Second, we continued our study of spin dynamics in storage rings. There is much current and proposed activity where spin polarized beams are being used in testing the Standard Model and its modifications. Our work has focused

    It is common knowledge that there are difficulties in convincing the general public and their democratically elected representatives that final disposal of spent nuclear fuel can be made in safe way. Special problems for the decision-makers are created by the demands put on today's generations to make a responsible risk assessment in a area with genuine uncertainties and characterised by any expressions of lack of confidence in social institutions. The current Swedish process for siting a deep repository for spent nuclear fuel has evolved during a period of many years, through inputs by the industry, Government, regulatory authorities and concerned municipalities. It is clear that the nuclear industry, represented by the Swedish Nuclear Fuel and Waste Management CO (SKB), has the full responsibility to find a solution to the waste management problem and to implement the solution - and to for this under the supervision of Government and regulating authorities. But, given the strong tradition of local self-government, the concerned municipalities, the local population in this process. this is simply the following fact: For people who have engaged themselves in local politics - and are prepared to take their responsibility for the well-being and development of their local community - the issue of a possible nuclear repository in the neighbourhood is difficult to handle. A relevant question is: Why should the nation as a whole expect these locally elected representatives to feel a responsibility for an issue of national importance? (author)

    Full Text Available Background: Over the past years, Greece has undergone several endeavors aimed at modernizing and improving national health care services with a focus on PHC. However, the extent to which integrated primary health care has been achieved is still questioned. Purpose: This paper explores the extent to which integrated primary health care (PHC is an issue in the current agenda of policy makers in Greece, reporting constraints and opportunities and highlighting the need for a policy perspective in developing integrated PHC in this Southern European country. Methods: A systematic review in PubMed/Medline and SCOPUS, along with a hand search in selected Greek biomedical journals was undertaken to identify key papers, reports, editorials or opinion letters relevant to integrated health care. Results: Our systematic review identified 198 papers and 161 out of them were derived from electronic search. Fifty-three papers in total served the scope of this review and are shortly reported. A key finding is that the long-standing dominance of medical perspectives in Greek health policy has been paving the way towards vertical integration, pushing aside any discussions about horizontal or comprehensive integration of care. Conclusion: Establishment of integrated PHC in Greece is still at its infancy, requiring major restructuring of the current national health system, as well as organizational culture changes. Moving towards a new policy-based model would bring this missing issue on the discussion table, facilitating further development.

  15. Arctic development and historical analysis: the use of historical methodology in addressing current issues in the Arctic.

    To demonstrate the applicability of historical methodology to current issues in the Canadian Arctic. This is a literature-based analytical historical study, which draws on material from database searches of MEDLINE, Anthropology Plus, POLARInfo, the Arctic Blue Books and Historical Abstracts. Material was also obtained from physical searches of the University of Alberta Libraries and Library and Archives Canada collections, as well as from field research in the records of the Inuulitsivik Maternities. The historical technique of tracing epistemological change over time, pioneered by Michel Foucault and further developed by Ian Hacking, was applied to the history of Canadian authority in the Arctic. This was linked with epistemological changes occurring throughout Western/Southern culture in this period. The applicability of this historical analysis for current issues in the region was then evaluated. An epistemological shift in Western society has moved authority from traditional human actors in government, medicine and, increasingly, science to statistics, which is seen as both impartial and accurate. Human authorities now routinely appeal to statistical authority to validate policy decisions. This change is as apparent in the Arctic as elsewhere, but it has also opened a space for Inuit practices, rooted in traditional Inuit epistemology, to reassert themselves, provided they can satisfy demands for statistical validity. Historical analysis provides a means to identify the spaces which epistemological change and historical contingency have opened in which social and cultural change can occur.

    Mr. Makoto Satake, Director of the Board and Deputy Executive General Manager, Nuclear Power Division, Tokyo Electric Power Company (TEPCO), was interviewed regarding his views on a series of questions related to the future of nuclear power plant construction and operation in Japan. Regarding nuclear power plant economics, he discusses what improvements should be made in the construction cost reduction area and in operation and maintenance costs to make costs more viable. Regarding public relations, he stated that regaining public trust is the most important today. Information disclosure to the public and two-way communication activities (direct discussions, public hearings, etc.) are being expanded. To improve economic competitiveness, two points are important: electric power generating cost reduction through stable operation and a legal framework that eliminates uncertainty by collecting funds to promote plutonium recycling and back-end costs. In the construction of a new plant, the coexistence of quality assurance and a shortened construction period are essential. It is necessary to decide on the design and on the construction process as early as possible. In Japan, 3D-computer aided design is used as the key technology for efficient construction. Moreover, in order to improve project management abilities, computer software aimed at process control and design information management has been developed using past construction experiences. The software will be applied to the next construction project. He cited the reasons why government support is essential for new plant construction, and in what ways existing nuclear power plants in Japan have improved in the last five years. As far as the best available technology for constructing plants, he recommended the large-block construction method and the all-weather construction method as effective construction technologies. The advanced boiling water reactor is best suited for plant construction in the future. Regarding human resources for the future, he noted the use of digital databases with several components, a Systematic Approach to Training method for reactor operators and other plant personnel, and the use of retired professionals to enhance technical skills and troubleshoot problems in advance

    The Japan Nuclear Human Resource Development Network (JN-HRD Net) was established in November 2010 with the aim of developing a framework for mutual cooperation and information sharing among nuclear-related organizations. Although the tasks and goals of developing human resources in the nuclear field have been shifted since the accident at the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Plant, the necessity of fostering capable personnel in this field stays unchanged and the importance of our network activities has further emphasized. The meeting of JN-HRD Net was held on the 5th of February 2013, where its activities by each field were reported and views and opinions were actively exchanged between more than 90 participants. This paper briefly describes current status and issues of JN-HRD Net and its general activities conducted by the JN-HRD Net secretariat. (J.P.N.)

    Probabilistic risk assessment (PRA) of Nuclear Power Plants (NPPs) could play an important role in assuring safety of NPPs. However PRA had not always effectively used, which was indicated in Japanese government's report on Fukushima Daiichi NPP accident. At the Risk Technical Committee (RTC) of Standards Committee of Atomic Energy Society of Japan, preparation of standards (implementing criteria) focusing on PRA methodology and investigation on basic philosophy for use of PRA had been in progress. Based on activities of RTC, a serial in three articles including this described current status and future expectation concerning probabilistic risk assessment of NPPs. This article introduced features and issues of PRA methodology related to the use of PRA. Features of PRA methodology could be shown as (1) systematic and comprehensive understanding of risk, (2) support of grading approach, (3) identification of effective safety upgrade measures and (4) quantitative understanding of effects of uncertainty. Issues of PRA methodology were (1) extension of PRA application area, (2) upgrade of PRA methodology, (3) quality assurance of PRA, (4) treatment of uncertainty and (5) quantitative evaluation criteria.

    The drug development of new anti-cancer agents is streamlined in response to the urgency of bringing effective drugs to market for patients with limited life expectancy. FDA's regulation of oncology drugs has evolved from the practices set forth in Arnold Lehman's seminal work published in the 1950s through the current drafting of a new International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) safety guidance for anti-cancer drug nonclinical evaluations. The ICH combines the efforts of the regulatory authorities of Europe, Japan, and the United States and the pharmaceutical industry from these three regions to streamline the scientific and technical aspects of drug development. The recent development of new oncology drug classes with novel mechanisms of action has improved survival rates for some cancers but also brings new challenges for safety evaluation. Here we present the legacy of Lehman and colleagues in the context of past and present oncology drug development practices and focus on some of the current issues at the center of an evolving harmonization process that will generate a new safety guidance for oncology drugs, ICH S9. The purpose of this new guidance will be to facilitate oncology drug development on a global scale by standardizing regional safety requirements.

    Full Text Available BACKGROUND: Surfactant replacement therapy is a recognized treatment for respiratory distress syndrome (RDS in the newborns. Over the past 30 years, human and animal trials have been performed regarding administration of aerosolized surfactant to the injured lung, however the result has been unsatisfactory when compared with instilled surfactant delivery via endotracheal tube (ETT. This review aims to investigate the current issues, challenges and future recommendation of aerosolized surfactant therapy. CONTENT: Five randomized clinical trials in humans and 13 animal trials met the inclusion criteria and were reviewed. Most animal trials agree that this method of treatment is feasible. However, human trials presented conflicting results, and generally showed it to be ineffective. When compared with surfactant delivery via ETT, aerosolized surfactant is less effective in improving respiratory function. SUMMARY: The current data from human trials does not support the implementation of aerosolized surfactant therapy to treat newborns with RDS. Further research is necessary to improve nebulization, delivery, distribution and deposition in the lung, to investigate aerosolized surfactant delivery via ETT and to determine the appropriate dose. KEYWORDS: surfactant, aerosol, prematurity, respiratory distress syndrome.

  8. Current issues surrounding the definition of trans-fatty acids: implications for health, industry and food labels.

    Wang, Ye; Proctor, Spencer D

    2013-10-01

    The definition of trans-fatty acids (TFA) was established by the Codex Alimentarius to guide nutritional and legislative regulations to reduce TFA consumption. Currently, conjugated linoleic acid (CLA) is excluded from the TFA definition based on evidence (primarily preclinical studies) implying health benefits on weight management and cancer prevention. While the efficacy of CLA supplements remains inconsistent in randomised clinical trials, evidence has emerged to associate supplemental CLA with negative health outcomes, including increased subclinical inflammation and oxidative stress (particularly at high doses). This has resulted in concerns regarding the correctness of excluding CLA from the TFA definition. Here we review recent clinical and preclinical literature on health implications of CLA and ruminant TFA, and highlight several issues surrounding the current Codex definition of TFA and how it may influence interpretation for public health. We find that CLA derived from ruminant foods differ from commercial CLA supplements in their isomer composition/distribution, consumption level and bioactivity. We conclude that health concerns associated with the use of supplemental CLA do not repudiate the exclusion of all forms of CLA from the Codex TFA definition, particularly when using the definition for food-related purposes. Given the emerging differential bioactivity of TFA from industrial v. ruminant sources, we advocate that regional nutrition guidelines/policies should focus on eliminating industrial forms of trans-fat from processed foods as opposed to all TFA per se.

    Full Text Available This paper uses Queer theory, specifically literature on Bowers v. Hardwick, to analyze debates over legislation proposed in Quebec regarding covered faces. Queer theory sheds light on legal responses to the veil. Parliamentary debates in Quebec reconstitute the polity, notably as secular and united. The paper highlights the contradictory and unstable character of four binaries: legislative text versus social practice, act versus status, majority versus minority, and knowable versus unknowable. As with contradictory propositions about homosexuality, contradiction does not undermine discourse but makes it stronger and more agile. Este artículo utiliza la teoría Queer, más concretamente la literatura sobre Bowers vs. Hardwick, para analizar los debates sobre la legislación propuesta en Quebec en relación al velo. La teoría Queer arroja luz sobre las respuestas legales al velo. Los debates parlamentarios en Quebec reconstituyen la forma de gobierno, especialmente como secular y unido. El documento pone de relieve el carácter contradictorio e inestable de cuatro binarios: texto legislativo frente a las prácticas sociales; legislación frente a estado; mayoría versus minoría; y conocible frente a incognoscible. Al igual que con las proposiciones contradictorias acerca de la homosexualidad, la contradicción no socava el discurso, sino que lo hace más fuerte y más ágil.

    Nuclear generating stations (NGSs) in Canada are operated by utilities in Ontario, Quebec, and New Brunswick. Ontario Hydro, with a committed nuclear program of 13,600 MW(electric) is the major producer of CANDU pressurized heavy-water reactor (PHWR) low- and intermediate-level radioactive wastes. All radioactive wastes with the exception of irradiated fuel are processed and retrievably stored at a centralized facility at the Bruce Nuclear Power Development site. Solid-waste classifications and annual production levels are given. Solid-waste management practices at the site as well as the physical, chemical, and radiochemical characteristics of the wastes are well documented. The paper summarizes types, current inventory, and estimated annual production rate of liquid waste. Operation of the tritium recovery facility at Darlington NGS, which removes tritium from heavy water and produces tritium gas in the process, gives rise to secondary streams of tritiated solid and liquid wastes, which will receive special treatment and packaging. In addition to the treatment of radioactive liquid wastes, there are a number of other important issues in low- and intermediate-level radioactive waste management that Ontario Hydro will be addressing over the next few years. The most pressing of these is the reduction of radioactive wastes through in-station material control, employee awareness, and improved waste characterization and segregation programs. Since Ontario Hydro intends to store retrievable wastes for > 50 yr, it is necessary to determine the behavior of wastes under long-term storage conditions

    According to the recent changes of working environments and socio-economical conditions, the proportion of working women are increasing in Japan. Characteristics of occupational workload and stress of Japanese working women are consistent with those in many industrialized countries except man-dominant culture. In this review we describe the history, current issues, and future research directions on occupational health of working women, especially focused on reproductive health, work-related musculo-skeletal disorders (WMSDs), and mental disorders. In the reproductive health survey, traditionally main concern was about pregnancy outcomes, then fecundity studies, such as time to pregnancy, became topics recently. Future research will be shifted to outcomes not only during pregnancy but also disorders of hormonal balance and climacterium or health conditions after menopause. WMSDs are reviewed on mainly gender difference and its causative factors. Historically, mental health of working women in Japan has focused on the job stress of nurses. We compare results with a lot of recent researches in Europe and U.S.A., where interaction between occupational stress and family roles were studied. It is not easy to predict the prospective status of female workers in Japan, but social, workplace and familial supports will enhance their health promotion.

    2017-05-01

    Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disease with a fatal outcome. This review aims to report key epidemiological features of ALS in relation to the hypothesis of variation between populations, to summarize environmental hypothesis and to highlight current issues that deserve much considerations. Epidemiological ALS studies have shown a variation of incidence, mortality and prevalence between geographical areas and different populations. These data could support the notion that genetic factors, especially populations' ancestries, along with environmental and lifestyle factors, play a significant role in the occurrence of the disease. To date, there is no strong evidence to confirm an association between a particular environmental factor and ALS. Physical activity (PA) has been extensively evaluated. Recent studies support with the best evidence level that PA in general population is not a risk factor for ALS. However, further research is needed to clarify the association of PA in some occupations and some athletic activities. Epidemiological research based on multicenter international collaboration is essential to provide new data on ALS especially in some regions of the world that are to date poorly represented in the ALS literature.

    The cerebellum controls descending motor commands by outputs to primary motor cortex (M1) and the brainstem in response to sensory feedback. The cerebellum may also modulate afferent input en route to M1 and the brainstem. The objective of this study is to determine if anodal transcranial direct current stimulation (tDCS) to the cerebellum influences cerebellar brain inhibition (CBI), short afferent inhibition (SAI) and trigeminal reflexes (TRs) in healthy adults. Data from two studies evaluating effects of cerebellar anodal and sham tDCS are presented. The first study used a twin coil transcranial magnetic stimulation (TMS) protocol to investigate CBI and combined TMS and cutaneous stimulation of the digit to assess SAI. The second study evaluated effects on trigemino-cervical and trigemino-masseter reflexes using peripheral nerve stimulation of the face. Fourteen right-handed healthy adults participated in experiment 1. CBI was observed at baseline and was reduced by anodal cerebellar DCS only (P < 0.01). There was SAI at interstimulus intervals of 25 and 30 ms at baseline (both P < 0.0001), but cerebellar tDCS had no effect. Thirteen right-handed healthy adults participated in experiment 2. Inhibitory reflexes were evoked in the ipsilateral masseter and sternocleidomastoid muscles. There was no effect of cerebellar DCS on either reflex. Anodal DCS reduced CBI but did not change SAI or TRs in healthy adults. These results require confirmation in individuals with neurological impairment.

  2. Successful decoding of famous faces in the fusiform face area.

    Directory of Open Access Journals (Sweden)

    Vadim Axelrod

    Full Text Available What are the neural mechanisms of face recognition? It is believed that the network of face-selective areas, which spans the occipital, temporal, and frontal cortices, is important in face recognition. A number of previous studies indeed reported that face identity could be discriminated based on patterns of multivoxel activity in the fusiform face area and the anterior temporal lobe. However, given the difficulty in localizing the face-selective area in the anterior temporal lobe, its role in face recognition is still unknown. Furthermore, previous studies limited their analysis to occipito-temporal regions without testing identity decoding in more anterior face-selective regions, such as the amygdala and prefrontal cortex. In the current high-resolution functional Magnetic Resonance Imaging study, we systematically examined the decoding of the identity of famous faces in the temporo-frontal network of face-selective and adjacent non-face-selective regions. A special focus has been put on the face-area in the anterior temporal lobe, which was reliably localized using an optimized scanning protocol. We found that face-identity could be discriminated above chance level only in the fusiform face area. Our results corroborate the role of the fusiform face area in face recognition. Future studies are needed to further explore the role of the more recently discovered anterior face-selective areas in face recognition.

    Purpose: The purpose of this work was to characterize commercially available optically stimulated luminescent (OSL) dosimeters for general clinical applications and apply the results to the development of a method to evaluate the efficacy of a vendor-specific organ-based tube current modulation application for both phantom and clinical computed tomography (CT) scans of the face and orbits. Methods: This study consisted of three components: (1) thorough characterization of the dosimeters for CT scans in phantom, including evaluations of depletion, fading, angular dependence, and conversion from counts to absorbed dose; (2) evaluation of the efficacy of using plastic glasses to position the dosimeters over the eyes in both phantom and clinical studies; and (3) preliminary dosimetry measurements made using organ-based tube current modulation in computed tomography dose index (CTDI) and anthropomorphic phantom studies. Results: (1) Depletion effects were found to have a linear relationship with the output of the OSL dosimeters (R{sup 2} = 0.96). Fading was found to affect dosimeter readings during the first two hours following exposure but had no effect during the remaining 60-h period observed. No significant angular dependence was observed for the exposure conditions used in this study (with p-values ranging from 0.9 to 0.26 for all t-tests). Dosimeter counts varied linearly with absorbed dose when measured in the center and 12 o’clock positions of the CTDI phantoms. These linear models of counts versus absorbed dose had overlapping 95% confidence intervals for the intercepts but not for the slopes. (2) When dosimeters were positioned using safety glasses, there was no adverse effect on image quality, and there was no statistically significant difference between this placement and placement of the dosimeters directly on the eyes of the phantom (p = 0.24).

    The Second CSNI Specialist Meeting on Simulators and Plant Analyzers: Current Issues in Nuclear Power Plant Simulation was held in Espoo, Finland, from September 29 through October 2, 1997. It was organised by CSNI Principal Working Group on Coolant System Behaviour (PWG2), Task Group on Thermal Hydraulic Applications (TG-THA), in co-operation with Technical Research Centre of Finland. The meeting in Espoo attracted some 90 participants from 17 countries. A total of 49 invited papers were presented in the meeting in addition to 7 simulator system demonstrations. Ample time was reserved for the presentations and informal discussions during the four meeting days. The previous meeting held in Lappeenranta, Finland, in 1992 collected some 85 participants from 12 countries, presenting a total of 40 papers. The meeting was structured into 6 sessions covering the important aspects of development and use of simulators and plant analyzers: Session I: New objectives, Requirements and Concepts. This session covered the progress experienced since the 1. simulator meeting and tried to address the changing role of simulators based on the changes in users' needs and developing possibilities. Session II: Trends in Simulation Technology. This session was reserved for studying the current trends in the simulation technology: software environments, visualisation, simulator configuration tools, programming languages and computer systems. Session III: Training and human factor studies using simulators. This session was created for studying the status of different uses of simulators such as educational simulators, human factor studies and integrated safety assessment in addition to traditional training. Regarding to the severe accidents, a question was raised whether the simulator use should be for training or education. Session IV: Modelling techniques. The session on modelling techniques was included to cover recent developments in the modelling techniques applicable to training

  2. Solar home systems. Insights from developing countries of the world. A literature survey of current issues and topics

    International Nuclear Information System (INIS)

    Dlamini, S.N.

    1999-08-01

    The study presents an overview of the main issues discussed and topics in regards and with relevance to Solar Home Systems. The main issues are grouped and discussed in five topics: financing, institutional arrangements, market opportunities, information and communication, and standards and quality control. Major challenges as far as projects are concerned, whether public or private, are highlighted, in particular regarding aspects of financing and institutional mechanisms. The up-front costs make Solar Home Systems out of reach for the greater number of people who need them most. On the other hand, sourcing private finance for renewable energy technologies in general, and Solar Home Systems in particular, has often been very difficult because of the perceived risks. Even if these funds would be available, weak institutional links often undermine project success. However, a handful of success stories exist today and could possibly be replicated elsewhere in the developing world. The subject of information dissemination needs to be revisited and clearly set in perspective. Several countries and organisations have now developed standards and technical norms, but universality and applicability are issues still at hands. 61 refs

  3. When the private sphere goes public: exploring the issues facing family caregiver organizations in the development of long-term care policies.

    Rozario, Philip A; Palley, Elizabeth

    2008-01-01

    Though family caregiving forms the backbone of the long-term care system in the United States, long-term care policies have traditionally focused on paid services that frail older people and people with disabilities utilize for their day-to-day functioning. Part of the exclusion of family caregiving from the long-term care discourse stems from the traditional separation of the private sphere, where family caregiving occurs, from the public sphere of policy making. However, the passage of the Family and Medical Leave Act (FMLA), the National Family Caregiver Support Program (NFCSP) and Medicaid waiver legislation may reflect recent changes in the government's position on their role in addressing issues related to the "private spheres." In this article, we explore the nature of family caregiving in the United States, the divide between the public and private spheres and provide an overview of family caregiving-related policies and programs in the U.S. In our review, we examine the provisions in the FMLA, NFCSP, and Medicaid waiver legislation that support family caregiving efforts. We also examine the roles of family caregiver organizations in making family caregiving an important element of long-term care policy and influencing policy-making.

The number of participants attending this series of meetings has been growing steadily, which reflects its increasing attraction. Our intention to bring together leading researchers, advanced students, and renowned scholars from various areas in order to stimulate new ideas and their exchange across the borders of specialization seems to bear fruit. In this way, the series of meetings has continued successfully from the beginning with DICE 2002 [1], followed by DICE 2004 [2], DICE 2006 [3], and DICE 2008 [4], uniting more than 100 participants representing almost 30 countries worldwide. It has been a great honour and inspiration to have Professor Luc Montagnier (Nobel Prize for Medicine 2008) from the World Foundation for AIDS Research and Prevention with us, who presented the lecture DNA waves and water (included in this volume). The discussions took place under the wider theme Space-Time-Matter - current issues in quantum mechanics and beyond in the very pleasant and inspiring atmosphere of Castello Pasquini, which - with its beautiful surroundings, overlooking the Tuscany coast - hosted the conference very successfully for the second time. The five-day program was grouped according to the following topics: Gravity and Quantum Mechanics Quantum Coherent Processes in Biology / Many-Body Systems From Quantum Foundations to Particle Physics The Deep Structure of Spacetime Quantum - Relativity - Cosmology A Public Roundtable Discussion formed an integral part of the program under the theme Sull' Onda Della Coerenza" - le nuove

    2011-01-01

    Full Text Available At the ideological level, the current crisis, as the others in history, has triggered an intellectual debate among several applicable ideas: ultra-liberal theory of the "invisible hand" of Adam Smith, Keynes's theory of state interventionism and even neo-Marxist theories. Globalization, with all its core components, generates a chain reaction when the phenomenon occurs, either positive or negative. The origin of the current financial crisis should be sought in the effects of massive cross-border capital flows and the use of more complex derivatives. Reaching the saturation of the three engines of economic growth worldwide in the period after the collapse of the socialist bloc is another important cause of all the failures that currently exist worldwide. Acquisition of toxic assets from bank balance sheets, their recapitalization and takeover by the state, but also the reinforcement of the prudential supervision of capitalization, liquidity and risk management system, improved transparency and speed the process of evaluating or reinforcing authorities' response to risk, can be considered short or long term anti-crisis measures, as appropriate.

    Exclusive breastfeeding (EBF) has been identified as the optimal nutrition and critical behavior in attaining human immunodeficiency virus (HIV)-free infant survival in resource-limited settings. Health-care providers (HCPs) in clinic- and community-settings throughout sub-Saharan Africa (sSA) provide infant-feeding counseling. However, rates of EBF at 6 months of age are suboptimal. HCPs are uniquely positioned to educate HIV-positive mothers and provide support by addressing known barriers to EBF. However, limited evidence exists on the experiences faced by HCPs in providing counseling on infant feeding to HIV-positive women. Our objective is to describe experiences faced by HCPs when delivering infant-feeding counseling in the context of HIV in program settings in sSA. We searched a range of electronic databases, including PubMed, CINAHL, and PsycINFO from January 1990 to February 2013, in addition to hand-searching, cross-reference searching, and personal communications. The search was limited to publications in English. Empirical studies of HCP experiences providing infant-feeding counseling in the prevention of mother-to-child transmission (PMTCT) of HIV programs in sSA were selected. We identified 10 peer-reviewed articles reporting HCP challenges in infant-feeding counseling that met inclusion criteria. Articles included qualitative, cross-sectional and mixed-method studies, and cumulatively reported 31 challenges faced by HCPs. Among the challenges identified, the most commonly reported were personal beliefs held by the HCPs toward infant feeding in the context of HIV, contradictory messages, staff workload, directive counseling styles, and a lack of practical strategies to offer mothers, often leading to improvised counseling approaches. Counseling strategies need to be developed that are relevant, meaningful, and responsive to the needs of both HCPs and mothers.

    Full Text Available Abstract Background Work-related injuries result in considerable morbidity, as well as social and economic costs. Pain associated with these injuries is a complex, contested topic, and narcotic analgesics (NA remain important treatment options. Factors contributing to NA utilization patterns are poorly understood. This qualitative study sought to characterize the factors contributing to NA utilization amongst injured workers from the perspectives of physicians and pharmacists. Methods The study employed concept mapping methodology, a structured process yielding a conceptual framework of participants' views on a particular topic. A visual display of the ideas/concepts generated is produced. Eligible physicians and pharmacists (n = 22 serving injured workers in the province of Ontario (Canada were recruited via purposive sampling, and participated in concept mapping activities (consisting of brainstorming, sorting, rating, and map exploration. Participants identified factors influencing NA utilization, and sorted these factors into categories (clusters. Next, they rated the factors on two scales: 'strength of influence on NA over-utilization' and 'amenability to intervention'. During follow-up focus groups, participants refined the maps and discussed the findings and their implications. Results 82 factors were sorted into 7 clusters: addiction risks, psychosocial issues, social/work environment factors, systemic-third party factors, pharmacy-related factors, treatment problems, and physician factors. These clusters were grouped into 2 overarching categories/regions on the map: patient-level factors, and healthcare/compensation system-level factors. Participants rated NA over-utilization as most influenced by patient-level factors, while system-level factors were rated as most amenable to intervention. One system-level cluster was rated highly on both scales (treatment problems - e.g. poor continuity of care, poor interprofessional communication

    Full Text Available The advent of digital technology and increased global connectivity has, to put it mildly, caused some ripples for the entertainment industry specifically and copyright law generally. In the aftermath, many are searching for new ways to incorporate the benefits of digital copies and the internet while minimizing the harms. To some, the anime industry and its fans offer examples of how an industry can benefit and even grow from allowing copyright infringement. This article examines the anime industry in-depth with this suggestion in mind and places the industry among current copyright policy debates, such as those suggested by Lawrence Lessig.

    2015-12-01

    There is little published research about mental health and climate change in the Pacific, including Solomon Islands. Solomon Islands has one of the highest rates of sea-level rise globally. The aim of this research was to document mental health issues related to sea-level rise for people in East Malaita, Solomon Islands. A cross-sectional study was carried out in six low-lying villages in East Malaita, Solomon Islands. The researcher travelled to villages by dugout canoe. In addition to quantitative, closed-ended questions, open-ended questions with villagers explored individual and community responses to rising sea level. Of 60 people asked, 57 completed the questionnaire. Of these, 90% reported having seen a change in the weather patterns. Nearly all participants reported that sea-level rise is affecting them and their family and is causing fear and worry on a personal and community level. Four themes emerged from the qualitative analysis: experience of physical impacts of climate change; worry about the future; adaptation to climate change; government response needed. Given predictions of ongoing sea-level rise in the Pacific it is essential that more research is conducted to further understand the human impact of climate change for small island states which will inform local, provincial and national-level mental health responses. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Despite the limited research on the effects of altitude (or hypoxic) training interventions on team-sport performance, players from all around the world engaged in these sports are now using altitude training more than ever before. In March 2013, an Altitude Training and Team Sports conference was held in Doha, Qatar, to establish a forum of research and practical insights into this rapidly growing field. A round-table meeting in which the panellists engaged in focused discussions concluded this conference. This has resulted in the present position statement, designed to highlight some key issues raised during the debates and to integrate the ideas into a shared conceptual framework. The present signposting document has been developed for use by support teams (coaches, performance scientists, physicians, strength and conditioning staff) and other professionals who have an interest in the practical application of altitude training for team sports. After more than four decades of research, there is still no consensus on the optimal strategies to elicit the best results from altitude training in a team-sport population. However, there are some recommended strategies discussed in this position statement to adopt for improving the acclimatisation process when training/competing at altitude and for potentially enhancing sea-level performance. It is our hope that this information will be intriguing, balanced and, more importantly, stimulating to the point that it promotes constructive discussion and serves as a guide for future research aimed at advancing the bourgeoning body of knowledge in the area of altitude training for team sports.

    In organic photovoltaic (PV) devices based on solution-processed small molecules, we report here that the physicochemical properties of the substrate are critical for achieving high-performances organic solar cells. Three different substrates were tested: ITO coated with PSS, ZnO sol-gel, and ZnO nanoparticles. PV performances are found to be low when the ZnO nanoparticles layer is used. This performance loss is attributed to the formation of many dewetting points in the active layer, because of a relatively high roughness of the ZnO nanoparticles layer, compared to the other layers. We successfully circumvented this phenomenon by adding a small quantity of polystyrene (PS) in the active layer. The introduction of PS improves the quality of film forming and reduces the dark currents of solar cells. Using this method, high-efficiency devices were achieved, even in the case of substrates with higher roughness.

    Full Text Available When Acadian students put forward a new, left-leaning brand of nationalism at the end of the 1960s, most observers concluded that it was simply a “spill-over” effect of Quebec’s “Quiet Revolution”. This paper will put forward the case that Acadian néo-nationalisme had a lot more to do with global currents of ideas than with Québécois nationalism. It is through a New Left inspired analysis of regional inequalities that Acadian student militants became aware of disparities between the province’s linguistic groups, and through the loose adoption of an anticolonial viewpoint that they reconciled themselves to the idea of nationalism. Moreover, at all times, these actors felt and imagined their struggle to be part of a broader progressive movement.

    The following report details the findings of a series of experiments and simulations performed on a commercially available, shuttle style golf cart during several maneuvers involving rapid accelerations of the vehicle. It is determined that the current set of passive restraints on these types of golf carts are not adequate in preventing ejection of a rear facing passenger during rapid accelerations in the forward and lateral directions. Experimental data and simulations show that a hip restraint must be a minimum of 13 in. above the seat in order to secure a rear facing passenger during sharp turns, compared to the current restraint height of 5 in. Furthermore, it is determined that a restraint directly in front of the rear facing passenger is necessary to prevent ejection. In addressing these issues, golf cart manufacturers could greatly reduce the likelihood of injury due to ejection of a rear facing, golf cart passenger. Copyright © 2013 Elsevier Ltd.

    The article presents submitted data of population dynamics of adolescent (10-17 years old) in Russian Federation over the period of 1995-2012 In the presence of reduction by 8.2 million of adolescent population the top-priority task of adolescent health and life maintenance was declared. The article deals with physical growth and development statistics of schoolchildren of 15-19 years old: as opposed to peers of 80-es increase of length, body weight and circumference of chest as well as reduction of muscle strength is observed. On the ground of the data analysis of authoritative statistical reporting the increase of morbidity rate by factor of 1.4 was detected over the last 10 years. It has been established that the true morbidity level is above the authoritative by the factor of 1.5. The number of adolescent at the age of 10-15 referred to 1st and 2nd health groups decreased almost on 20%, at the same time pathological processes become chronic. The reproductive and mental health of adolescent at the age of 15-17 years was analyzed over the last 10 years. The rate of mental health disorders in adolescent living in country is more than in the peers living in cities by the factor of 1.2-1.4. The rate of period disorders, salpingitis and oothecitis increased in girls under 10 years and ones at the age of 15-17. The rate and structure of child disability was analyzed. It was fixed that leading causes of adolescent disability are mental disorders, diseases of nervous system, congenital anomalies. The most commonly encountered seed of physical dysfunction is capacity to study. It is demonstrated that there is misreporting on both child disability in totally and adolescent disability in Russian Federation. After the analysis of particular provisions of legislation concerning medical and social issues of child disability the week points were detected. The morbidity rate of adolescent was studied: primary cause of death in adolescent is extrinsic factor (more than 70%), the

  6. The current status of mitigation, experience and repair regarding Alloy 600 issues on Japanese steam generator nozzles

    One conspicuous problem seen in aged PWR plants is the PWSCC, which is considered to be caused by three factors, which are environment, material and stress. The degradation caused by PWSCC on high nickel content alloy (Alloy 600) at dissimilar material weld joints of steam generator nozzles has became conspicuous in Japan. This paper describes the mitigation technique used for the PWSCC, recent experiences on PWSCC issues and repair techniques implemented on Japanese steam generator nozzles with Alloy 600 weld. As a countermeasure against the PWSCC, ultrasonic shot peening (USP) was planned and conducted on the SG nozzles as a preventive maintenance in Japan. It has been confirmed that the stress near the inner surface can be converted into compressive stress by applying plastic strain to the surface using collision force of the shot material during the shot peening. USP employs the ultrasonic-wave vibration. The effects of this peening technique were confirmed by qualified test if there were undetectable cracks by ECT on the surface of the material. In Japan, there were 15 plants with SG nozzles which had Alloy 600 welds and these SG nozzles were inspected by ECT or VT as a confirmatory inspection before conducting the USP operation from 2006 to 2008. In these inspections, defects have been found at 19 hot nozzles in 8 plants. In addition, the defect in one of the plants has been found at the safe-end base metal made from stainless steel. In the root cause investigation result, it was confirmed that these cracks were typical PWSCC induced by high residual stress. These nozzles with defects were repaired by replacing the Alloy 600 welding material on surfaces exposed to primary water with the Alloy 690 welding material which has excellent PWSCC resistance. These material replacements were performed by cladding or replacement of nozzle safe end joint. These techniques are used not only to repair but also as a preventive maintenance. These mitigation or repair

    Environmental policies and regulations are having profound effects on the oil industry. The industry is affected by controls on both its production and processing activities and on the use of its own products. The environmental impacts of upstream activities, epitomized by the Exxon Valdez accident, are leading to more expensive tanker designs. Oil markets can be changed by sulphur controls driven by concern about acid rain and new requirements in the USA to change gasoline specifications in order to reduce urban smog. The problem of climate change and CO 2 emissions poses even more fundamental challenges to the oil industry, with the prospect of reduced markets in the longer term. (author)

    Biomarker research does not exist in isolation. Its usefulness can only be realized when it is translated into prevention strategies to protect public health. In the context of air toxics, these prevention strategies begin with the development of regulatory standards derived from risk assessment schemes. The Clean Air Act Amendments of 1990 list 189 air toxics, including many volatile organics, metals, and pesticides. The National Institute of Environmental Health Sciences (NIEHS), through its affiliation with the National Toxicology Program, has generated toxicity and carcinogenicity data on more than 100 of these air toxics. The NIEHS extramural and intramural research portfolios support a variety of projects that develop and validate biomarkers for use in environmental health science and risk assessment. Biomarkers have a tremendous potential in the areas of regulating air toxics and protecting public health. Risk assessors need data provided by biomarkers of exposure, biomarkers of close/pharmacokinetics, biomarkers of susceptibility or individual variability, and biomarkers of effects. The greatest benefit would be realized if biomarkers could be employed in four areas of primary and secondary prevention. The first is the use of biomarkers to enhance extrapolation of animal data to human exposure situations in establishing risk standards. The second is the use of biomarkers that assess noncancer, as well as cancer, end points. Important health end points include pulmonary dysfunction, immunotoxicity, and neurotoxicity. Third, biomarkers that serve as early warning signs to detect intermediate effects would enhance our ability to design timely and cost-effective intervention strategies. Finally, biomarkers used to evaluate the effectiveness of intervention strategies both in clinical and regulatory settings, would enable us to ensure that programs designed to protect public health do, in fact, achieve the desired outcome. 9 refs., 2 tabs.

    Ensuring that low- and moderate-income (LMI) households have access to energy efficiency is equitable, provides energy savings as a resource to meet energy needs, and can support multiple policy goals, such as affordable energy, job creation, and improved public health. Although the need is great, many LMI households may not be able to afford efficiency improvements or may be inhibited from adopting efficiency for other reasons. Decision-makers across the country are currently exploring the challenges and potential solutions to ramping up adoption of efficiency in LMI households, including the use of financing. The report’s objective is to offer state and local policymakers, state utility regulators, program administrators, financial institutions, consumer advocates and other LMI stakeholders with an understanding of: -The relationship between LMI communities and financing for energy efficiency, including important considerations for its use such as consumer protections -The larger programmatic context of grant-based assistance and other related resources supporting LMI household energy efficiency -Lessons learned from existing energy efficiency financing programs serving LMI households -Financing products used by these programs and their relative advantages and disadvantages in addressing barriers to financing or to energy efficiency uptake for LMI households

  12. Current State of Climate Education in the United States: Are Graduate Students being Adequately Prepared to Address Climate Issues?

    Climate change is happening; scientists have already observed changes in sea level, increases in atmospheric carbon dioxide, and declining polar ice. The students of today are the leaders of tomorrow, and it is our duty to make sure they are well equipped and they understand the implications of climate change as part of their research and professional careers. Graduate students, in particular, are gaining valuable and necessary research, leadership, and critical thinking skills, but we need to ensure that they are receiving the appropriate climate education in their graduate training. Previous studies have primarily focused on capturing the K-12, college level, and general publics' knowledge of the climate system, concluding with recommendations on how to improve climate literacy in the classroom. While this is extremely important to study, very few studies have captured the current perception that graduate students hold regarding the amount of climate education being offered to them. This information is important to capture, as it can inform future curriculum development. We developed and distributed a nationwide survey (495 respondents) for graduate students to capture their perception on the level of climate system education being offered and their view on the importance of having climate education. We also investigated differences in the responses based on either geographic area or discipline. We compared how important graduate students felt it was to include climate education in their own discipline versus outside disciplines. The authors will discuss key findings from this ongoing research.

    Full Text Available Patrick P Kneeland, Margaret C FangThe University of California, San Francisco Division of Hospital Medicine, San Francisco, CA, USAAbstract: Warfarin therapy reduces morbidity and mortality related to thromboembolism. Yet adherence to long-term warfarin therapy remains challenging due to the risks of anticoagulantassociated complications and the burden of monitoring. The aim of this paper is to review determinants of adherence and persistence on long-term anticoagulant therapy for atrial fibrillation and venous thromboembolism. We evaluate what the current literature reveals about the impact of warfarin on quality of life, examine warfarin trial data for patterns of adherence, and summarize known risk factors for warfarin discontinuation. Studies suggest only modest adverse effects of warfarin on quality of life, but highlight the variability of individual lifestyle experiences of patients on warfarin. Interestingly, clinical trials comparing anticoagulant adherence to alternatives (such as aspirin show that discontinuation rates on warfarin are not consistently higher than in control arms. Observational studies link a number of risk factors to warfarin non-adherence including younger age, male sex, lower stroke risk, poor cognitive function, poverty, and higher educational attainment. In addition to differentiating the relative impact of warfarin-associated complications (such as bleeding versus the lifestyle burdens of warfarin monitoring on adherence, future investigation should focus on optimizing patient education and enhancing models of physician–patient shared-decision making around anticoagulation.Keywords: anticoagulation, warfarin, adherence, persistence, thromboembolism

  14. Exploring Ivorian perspectives on the effectiveness of the current Ivorian science curriculum in addressing issues related to HIV/AIDS

    Ado, Gustave Firmin

    School-based HIV/AIDS science education has the potential to impact students when integrated into the science curriculum. However, this mixed method study shows that school-based HIV/AIDS science education is often not infused into career subjects such as science education but integrated into civics education and taught by teachers who lack the skills, knowledge, and the training in the delivery of effective school HIV/AIDS education. Since science is where biological events take place, it is suggested that HIV/AIDS science merits being taught in the science education classroom. This study took place in nine public middle schools within two school districts in Abidjan, Ivory Coast, one major urban city in the southern region. The study utilized triangulation of multiple data sources---both qualitative and quantitative. To substantiate the claims made in this study, a range of qualitative methods such as field notes and individual interviews with 39 teachers, 63 sixth grade students, 8 school administrators, and 20 community elders were used. For the quantitative portion 140 teachers and 3510 sixth grade students were surveyed. The findings from the study prioritize science education that includes HIV/AIDS science education for all, with emphasis on HIV/AIDS prevention in Ivory Coast. The factors that influence the implementation of HIV/AIDS curricula within the Ivorian sixth grade classrooms are discussed. Interview and survey data from students, teachers, school administrators, and community elders indicate that in the Ivorian school setting, "gerontocratic" cultural influences, religious beliefs, personal cultural beliefs, and time spent toward the discourse on HIV/AIDS have led to HIV/AIDS education that is often insufficient to change either misconceptions about HIV/AIDS or risky practices. It was also found that approaches to teaching HIV/AIDS does not connect with youth cultures. By reframing and integrating current HIV/AIDS curricula into the science

  16. Current signal of silicon detectors facing charged particles and heavy ions; Reponse en courant des detecteurs silicium aux particules chargees et aux ions lourds

    Energy Technology Data Exchange (ETDEWEB)

    Hamrita, H

    2005-07-01

    This work consisted in collecting and studying for the first time the shapes of current signals obtained from charged particles or heavy ions produced by silicon detectors. The document is divided into two main parts. The first consisted in reducing the experimental data obtained with charged particles as well as with heavy ions. These experiments were performed at the Orsay Tandem and at GANIL using LISE. These two experiments enabled us to create a data base formed of current signals with various shapes and various times of collection. The second part consisted in carrying out a simulation of the current signals obtained from the various ions. To obtain this simulation we propose a new model describing the formation of the signal. We used the data base of the signals obtained in experiments in order to constrain the three parameters of our model. In this model, the charge carriers created are regarded as dipoles and their density is related to the dielectric polarization in the silicon detector. This phenomenon induces an increase in permittivity throughout the range of the incident ion and consequently the electric field between the electrodes of the detector is decreased inside the trace. We coupled with this phenomenon a dissociation and extraction mode of the charge carriers so that they can be moved in the electric field. (author)

  17. Current and future research on corrosion and thermalhydraulic issues of HLM cooled reactors and on LMR fuels for fast reactor systems

    International Nuclear Information System (INIS)

    Knebel, J.U.; Konings, R.J.M.

    2002-01-01

    Heavy liquid metals (HLM) such as lead (Pb) or lead-bismuth eutectic (Pb-Bi) are currently investigated world-wide as coolant for nuclear power reactors and for accelerator driven systems (ADS). Besides the advantages of HLM as coolant and spallation material, e.g. high boiling point, low reactivity with water and air and a high neutron yield, some technological issues, such as high corrosion effects in contact with steels and thermalhydraulic characteristics, need further experimental investigations and physical model improvements and validations. The paper describes some typical HLM cooled reactor designs, which are currently considered, and outlines the technological challenges related to corrosion, thermalhydraulic and fuel issues. In the first part of the presentation, the status of presently operated or planned test facilities related to corrosion and thermalhydraulic questions will be discussed. First approaches to solve the corrosion problem will be given. The approach to understand and model thermalhydraulic issues such as heat transfer, turbulence, two-phase flow and instrumentation will be outlined. In the second part of the presentation, an overview will be given of the advanced fuel types that are being considered for future liquid metal reactor (LMR) systems. Advantages and disadvantages will be discussed in relation to fabrication technology and fuel cycle considerations. For the latter, special attention will be given to the partitioning and transmutation potential. Metal, oxide and nitride fuel materials will be discussed in different fuel forms and packings. For both parts of the presentation, an overview of existing co-operations and networks will be given and the needs for future research work will be identified. (authors)

    Coastal zones and the biosphere as a whole show signs of cumulative degradation due to the use and disposal of plastics. To better understand the manifestation of plastic pollution in the Atlantic Ocean, we partnered with local communities to determine the concentrations of micro-plastics in 125 beaches on three islands in the Canary Current: Lanzarote, La Graciosa, and Fuerteventura. We found that, in spite of being located in highly-protected natural areas, all beaches in our study area are exceedingly vulnerable to micro-plastic pollution, with pollution levels reaching concentrations greater than 100 g of plastic in 1l of sediment. This paper contributes to ongoing efforts to develop solutions to plastic pollution by addressing the questions: (i) Where does this pollution come from?; (ii) How much plastic pollution is in the world's oceans and coastal zones?; (iii) What are the consequences for the biosphere?; and (iv) What are possible solutions?

    2015-01-01

    It has been previously established that extraverts who are skilled at interpersonal interaction perform significantly better than introverts on a face-specific recognition memory task. In our experiment we further investigate the relationship between extraversion and face recognition, focusing on famous face recognition and face matching. Results indicate that more extraverted individuals perform significantly better on an upright famous face recognition task and show significantly larger face inversion effects. However, our results did not find an effect of extraversion on face matching or inverted famous face recognition.

    The mining sector is growing in parallel with societal demands for minerals. One of the most important environmental issues and economic burdens of industrial mining on land is the safe storage of the vast amounts of waste produced. Traditionally, tailings have been stored in land dams, but the lack of land availability, potential risk of dam failure and topography in coastal areas in certain countries results in increasing disposal of tailings into marine systems. This review describes the different submarine tailing disposal methods used in the world in general and in Norway in particular, their impact on the environment (e.g. hyper-sedimentation, toxicity, processes related to changes in grain shape and size, turbidity), current legislation and need for future research. Understanding these impacts on the habitat and biota is essential to assess potential ecosystem changes and to develop best available techniques and robust management plans.

    2011-01-01

    Adaptation to a visual pattern can alter the sensitivities of neuronal populations encoding the pattern. However, the functional roles of adaptation, especially in high-level vision, are still equivocal. In the present study, we performed three experiments to investigate if face gender adaptation could affect gender discrimination. Experiments 1 and 2 revealed that adapting to a male/female face could selectively enhance discrimination for male/female faces. Experiment 3 showed that the discrimination enhancement induced by face adaptation could transfer across a substantial change in three-dimensional face viewpoint. These results provide further evidence suggesting that, similar to low-level vision, adaptation in high-level vision could calibrate the visual system to current inputs of complex shapes (i.e. face) and improve discrimination at the adapted characteristic.

    2012-01-01

    Systematics is nowadays facing new challenges with the introduction of new concepts and new techniques. Compared to most other phyla, phylogenetic relationships among sponges are still largely unresolved. In the past 10 years, the classical taxonomy has been completely overturned and a review of the state of the art appears necessary. The field of taxonomy remains a prominent discipline of sponge research and studies related to sponge systematics were in greater number in the Eighth World Sponge Conference (Girona, Spain, September 2010) than in any previous world sponge conferences. To understand the state of this rapidly growing field, this chapter proposes to review studies, mainly from the past decade, in sponge taxonomy, nomenclature and phylogeny. In a first part, we analyse the reasons of the current success of this field. In a second part, we establish the current sponge systematics theoretical framework, with the use of (1) cladistics, (2) different codes of nomenclature (PhyloCode vs. Linnaean system) and (3) integrative taxonomy. Sponges are infamous for their lack of characters. However, by listing and discussing in a third part all characters available to taxonomists, we show how diverse characters are and that new ones are being used and tested, while old ones should be revisited. We then review the systematics of the four main classes of sponges (Hexactinellida, Calcispongiae, Homoscleromorpha and Demospongiae), each time focusing on current issues and case studies. We present a review of the taxonomic changes since the publication of the Systema Porifera (2002), and point to problems a sponge taxonomist is still faced with nowadays. To conclude, we make a series of proposals for the future of sponge systematics. In the light of recent studies, we establish a series of taxonomic changes that the sponge community may be ready to accept. We also propose a series of sponge new names and definitions following the PhyloCode. The issue of phantom species

    In traditional "face to face" lessons, during the time the teacher writes on a black or white board, the students are always behind the teacher. Sometimes, this happens even in the recorded lesson in videos. Most of the time during the lesson, the teacher shows to the students his back not his face. We do not think the term "face to…

  9. About-face on face recognition ability and holistic processing.

    Science.gov (United States)

    Richler, Jennifer J; Floyd, R Jackie; Gauthier, Isabel

    2015-01-01

    Previous work found a small but significant relationship between holistic processing measured with the composite task and face recognition ability measured by the Cambridge Face Memory Test (CFMT; Duchaine & Nakayama, 2006). Surprisingly, recent work using a different measure of holistic processing (Vanderbilt Holistic Face Processing Test [VHPT-F]; Richler, Floyd, & Gauthier, 2014) and a larger sample found no evidence for such a relationship. In Experiment 1 we replicate this unexpected result, finding no relationship between holistic processing (VHPT-F) and face recognition ability (CFMT). A key difference between the VHPT-F and other holistic processing measures is that unique face parts are used on each trial in the VHPT-F, unlike in other tasks where a small set of face parts repeat across the experiment. In Experiment 2, we test the hypothesis that correlations between the CFMT and holistic processing tasks are driven by stimulus repetition that allows for learning during the composite task. Consistent with our predictions, CFMT performance was correlated with holistic processing in the composite task when a small set of face parts repeated over trials, but not when face parts did not repeat. A meta-analysis confirms that relationships between the CFMT and holistic processing depend on stimulus repetition. These results raise important questions about what is being measured by the CFMT, and challenge current assumptions about why faces are processed holistically.

  10. Barriers facing junior doctors in rural practice.

    2005-01-01

    Early postgraduate, or junior doctors, are still required to practise in rural and remote communities, and they continue to face numerous issues and difficulties. Within the hospital setting, exposure to rural practice appears to be very limited during internship, and also to some extent, during the second postgraduate year and beyond. This is a major issue for those required to undertake country relieving, rural terms or who will be bonded to rural and remote practice for several years after internship. This research investigated the current issues and difficulties faced by junior doctors, required to undertake rural and remote practice in Queensland, Australia. An exploratory study was undertaken. Primary data were collected through semi-structured interviews held with key stakeholders. Stakeholders included: directors of clinical training; medical educators; junior doctors; rural practitioners; academic rural practitioners; and medical administrators. Of the 23 people approached, a total of 19 agreed to be interviewed. The response rate was 82.6%. Similar to the issues identified in the literature, there are currently a number of barriers influencing the ability of junior doctors to practise competently and confidently when undertaking practice in rural and remote communities. Minimal clinical experience, lack of supervision and on-site support, inadequate orientation and uninformed expectations, limited access to relevant education, and the influence of isolation, results in an overall lack of preparation both professionally and personally. When asked, respondents supported the identification of core skills and knowledge, and integration of these and other issues affecting rural practice, into their hospital-based programs. Current hospital-based education and training programs were not adequately preparing junior doctors for rural and remote practice. It was commented that orientation and education, with a rural emphasis, could assist junior doctors in their

    1991-01-01

    This document summarizes results of the Conceptual Design Activities (1988-1990) for the International Thermonuclear Experimental Reactor (ITER) project, namely those that pertain to the plasma facing components of the reactor vessel, of which the main components are the first wall and the divertor plates. After an introduction and an executive summary, the principal functions of the plasma-facing components are delineated, i.e., (i) define the low-impurity region within which the plasma is produced, (ii) absorb the electromagnetic radiation and charged-particle flux from the plasma, and (iii) protect the blanket/shield components from the plasma. A list of critical design issues for the divertor plates and the first wall is given, followed by discussions of the divertor plate design (including the issues of material selection, erosion lifetime, design concepts, thermal and mechanical analysis, operating limits and overall lifetime, tritium inventory, baking and conditioning, safety analysis, manufacture and testing, and advanced divertor concepts) and the first wall design (armor material and design, erosion lifetime, overall design concepts, thermal and mechanical analysis, lifetime and operating limits, tritium inventory, baking and conditioning, safety analysis, manufacture and testing, an alternative first wall design, and the limiters used instead of the divertor plates during start-up).

  12. Beyond Faces and Expertise

    Science.gov (United States)

    Zhao, Mintao; Bülthoff, Heinrich H.; Bülthoff, Isabelle

    2016-01-01

    Holistic processing—the tendency to perceive objects as indecomposable wholes—has long been viewed as a process specific to faces or objects of expertise. Although current theories differ in what causes holistic processing, they share a fundamental constraint for its generalization: Nonface objects cannot elicit facelike holistic processing in the absence of expertise. Contrary to this prevailing view, here we show that line patterns with salient Gestalt information (i.e., connectedness, closure, and continuity between parts) can be processed as holistically as faces without any training. Moreover, weakening the saliency of Gestalt information in these patterns reduced holistic processing of them, which indicates that Gestalt information plays a crucial role in holistic processing. Therefore, holistic processing can be achieved not only via a top-down route based on expertise, but also via a bottom-up route relying merely on object-based information. The finding that facelike holistic processing can extend beyond the domains of faces and objects of expertise poses a challenge to current dominant theories. PMID:26674129

    Full Text Available Interview with Professor N. Kosolapov is devoted to the most urgent and complex problems of modern international relations and world politics, reveals the current state of political psychology in Russia and abroad, as well as the evolution of the science. As estimated by N. Kosolapov, the viability of political-psychological projects in Russia has fallen sharply compared to 1990's. They are not fully used in the development of political strategies, as well as in the process of operational decision making and its realization. In the interview are marked the obstacles to the emergence of theoretical and applied research in Russia, as well as key milestones for future development of political psychology. It also touches upon the most important questions of psychology of leadership within the framework of modern Russian and international practice, the political process as a whole, shows the differences in the approaches of European and Russian scientific schools in the analysis of political leadership. The author’s vision of key issues of contemporary international relations is of particular interest: we are witnessing the fact that American global leadership is experiencing an acute crisis, which contributes to the escalation of inter-state conflicts. However, the positive effect of the international crisis for our country is that it led the elites to reconsider their own ideological guidance with respect to Russia's role in world politics and forced to fight for the «new position».

    Grenier, J Letitia; Davis, Jay A

    2010-01-01

    The SBSPRP is an extensive tidal wetland restoration project that is underway at the margin of South San Francisco Bay, California. The Project, which aims to restore former salt ponds to tidal marsh and manage other ponds for water bird support, is taking place in the context of a highly urbanized watershed and an Estuary already impacted by chemical contaminants. There is an intimate relationship between water quality in the watershed, the Bay, and the transitional wetland areas where the Project is located. The Project seeks to restore habitat for endangered and endemic species and to provide recreational opportunities for people. Therefore, water quality and bioaccumulation of contaminants in fish and wildlife is an important concern for the success of the Project. Mercury, PCBs, and PBDEs are the persistent contaminants of greatest concern in the region. All of these contaminants are present at elevated concentrations both in the abiotic environment and in wildlife. Dioxins, pyrethroids, PAHs, and selenium are also problematic. Organochlorine insecticides have historically impacted the Bay, and they remain above thresholds for concern in a small proportion of samples. Emerging contaminants, such as PFCs and non-PBDE flame retardants, are also an important water quality issue. Beyond chemical pollutants, other concerns for water quality in South San Francisco Bay exist, and include biological constituents, especially invasive species, and chemical attributes, such as dissolved oxygen and salinity. Future changes, both from within the Project and from the Bay and watershed, are likely to influence water quality in the region. Project actions to restore wetlands could worsen, improve, or not affect the already impaired water quality in South Bay. Accelerated erosion of buried sediment as a consequence of Project restoration actions is a potentially serious regional threat to South Bay water and sediment quality. Furthermore, the planned restoration of salt ponds

    We believe that in the present thematic issue we have succeeded in capturing an important part of the modern European research dynamic in the field of migration. In addition to well-known scholars in this field several young authors at the beginning their research careers have been shortlisted for the publication. We are glad of their success as it bodes a vibrancy of this research area in the future. At the same time, we were pleased to receive responses to the invitation from representatives of so many disciplines, and that the number of papers received significantly exceeded the maximum volume of the journal. Recognising and understanding of the many faces of migration are important steps towards the comprehensive knowledge needed to successfully meet the challenges of migration issues today and even more so in the future. It is therefore of utmost importance that researchers find ways of transferring their academic knowledge into practice – to all levels of education, the media, the wider public and, of course, the decision makers in local, national and international institutions. The call also applies to all authors in this issue of the journal.

  2. Reforming health care in Canada: current issues La reforma del sistema de atención a la salud en Canadá: situación actual

    Directory of Open Access Journals (Sweden)

    Enis Baris

    1998-05-01

    Full Text Available This paper examines the current health care reform issues in Canada. The provincial health insurance plans of the 1960s and 1970s had the untoward effects of limiting the federal government’s clout for cost control and of promoting a system centered on inpatient and medical care. Recently, several provincial commissions reported that the current governance structures and management processes are outmoded in light of new knowledge, new fiscal realities and the evolution of power among stake-holders. They recommend decentralized governance and restructuring for better management and more citizen participation. Although Canada’s health care system remains committed to safeguarding its guiding principles, the balance of power may be shifting from providers to citizens and "technocrats". Also, all provinces are likely to increase their pressure on physicians by means of salary caps, by exploring payment methods such as capitation, limiting access to costly technology, and by demanding practice changes based on evidence of cost-effectiveness.Este artículo examina los temas más recientes en las reformas del sistema de atención a la salud en Canadá.

    Beryllium is a candidate armour material for the in-vessel components of the International Thermonuclear Experimental Reactor (ITER), namely the primary first wall, the limiter, the baffle and the divertor. However, a number of issues arising from the performance requirements of the ITER plasma facing components (PFCs) must be addressed to better assess the attractiveness of Be as armour for these different components. These issues include heat loading limits arising from temperature and stress constraints under steady state conditions, armour lifetime including the effects of sputtering erosion as well as vaporisation and loss of melt during disruption events, tritium retention and permeation, and chemical hazards, in particular with respect to potential Be/steam reaction. Other issues such as fabrication and the possibility of in-situ repair are not performance-dependent but have an important impact on the overall assessment of Be as PFC armour. This paper describes the present view on Be application for ITER PFCs. The key issues are discussed including an assessment of the current level of understanding based on analysis and experimental data; and on-going activities as part of the ITER EDA R and D program are highlighted.

    2007-04-01

    This newsletter contains information on the Centre for Advanced Safety Assessment Tools (CASAT), the new strategy for the recovery of radioactive sources, the Technical Support Organization Conference and a message form the Director of the Division of Nuclear Installation Safety. To improve the efficiency of safety assessment methods, ensure transparency in their validation and application and establish an excellent knowledge base and training programmes, the IAEA's Centre for Advanced Safety Assessment Tools (CASAT) has therefore been formed. The Centre addresses the need for continuous technical support mechanisms for safety assessment methods. It provides support to Member States to enhance their safety assessment capabilities for present and future generations of nuclear systems, with a special focus on countries with a developing nuclear technology and nuclear safety infrastructure. It serves as a consolidated repository of relevant safety analysis knowledge, provides for focused training including advanced analytical simulations, and supports collaboration on safety assessment projects among Member States. The resources provided through CASAT include codes, models, databases, verification and validation information, analytical procedures and guides. The main purpose of the recently established Radioactive Source Technical Coordination Group (RSTCG) is to facilitate the technical coordination of activities of the IAEA related to the control and management of radioactive sources through the development of common approaches in technical matters and to advise the management of the relevant Divisions. It is the task of the RSTCG to provide the programme managers of the participating divisions/sections with a common opinion/advice on technical issues related to the control and management of radioactive sources. The RSTCG members obtain, inter alia from programme managers, information on all relevant project proposals, and share relevant materials in due time to

    Cognitive models propose that face recognition is accomplished through a series of discrete stages, including perceptual representation of facial structure, and encoding and retrieval of facial information. This implies that impaired face recognition can result from failures of face perception, face memory, or both. Studies of acquired prosopagnosia, autism spectrum disorders, and the development of normal face recognition support the idea that face perception and face memory are distinct processes, yet this distinction has received little attention in developmental prosopagnosia (DP). To address this issue, we tested the face perception and face memory of children and adults with DP. By definition, face memory is impaired in DP, so memory deficits were present in all participants. However, we found that all children, but only half of the adults had impaired face perception. Thus, results from adults indicate that face perception and face memory are dissociable, while the results from children provide no evidence for this division. Importantly, our findings raise the possibility that DP is qualitatively different in childhood versus adulthood. We discuss theoretical explanations for this developmental pattern and conclude that longitudinal studies are necessary to better understand the developmental trajectory of face perception and face memory deficits in DP.

    Exercise psychology encompasses the disciplines of psychiatry, clinical and counseling psychology, health promotion, and the movement sciences. This emerging field involves diverse mental health issues, theories, and general information related to physical activity and exercise. Numerous research investigations across the past 20 years have shown both physical and psychological benefits from physical activity and exercise. Exercise psychology offers many opportunities for growth while positively influencing the mental and physical health of individuals, communities, and society. However, the exercise psychology literature has not addressed ethical issues or dilemmas faced by mental health professionals providing exercise psychology services. This initial discussion of ethical issues in exercise psychology is an important step in continuing to move the field forward. Specifically, this article will address the emergence of exercise psychology and current health behaviors and offer an overview of ethics and ethical issues, education/training and professional competency, cultural and ethnic diversity, multiple-role relationships and conflicts of interest, dependency issues, confidentiality and recording keeping, and advertisement and self-promotion.

  13. Familiar face + novel face = familiar face? Representational bias in the perception of morphed faces in chimpanzees

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Highly social animals possess a well-developed ability to distinguish the faces of familiar from novel conspecifics to induce distinct behaviors for maintaining society. However, the behaviors of animals when they encounter ambiguous faces of familiar yet novel conspecifics, e.g., strangers with faces resembling known individuals, have not been well characterised. Using a morphing technique and preferential-looking paradigm, we address this question via the chimpanzee’s facial–recognition abilities. We presented eight subjects with three types of stimuli: (1 familiar faces, (2 novel faces and (3 intermediate morphed faces that were 50% familiar and 50% novel faces of conspecifics. We found that chimpanzees spent more time looking at novel faces and scanned novel faces more extensively than familiar or intermediate faces. Interestingly, chimpanzees looked at intermediate faces in a manner similar to familiar faces with regards to the fixation duration, fixation count, and saccade length for facial scanning, even though the participant was encountering the intermediate faces for the first time. We excluded the possibility that subjects merely detected and avoided traces of morphing in the intermediate faces. These findings suggest a bias for a feeling-of-familiarity that chimpanzees perceive familiarity with an intermediate face by detecting traces of a known individual, as 50% alternation is sufficient to perceive familiarity.

  14. The complex duration perception of emotional faces: Effects of face direction

    Full Text Available The perceived duration of emotional face stimuli strongly depends on the expressed emotion. But, emotional faces also differ regarding a number of other features like gaze, face direction, or sex. Usually, these features have been controlled by only using pictures of female models with straight gaze and face direction. Doi and Shinohara (2009 reported that an overestimation of angry faces could only be found when the model’s gaze was oriented towards the observer. We aimed at replicating this effect for face direction. Moreover, we explored the effect of face direction on the duration perception sad faces. Controlling for the sex of the face model and the participant, female and male participants rated the duration of neutral, angry and sad face stimuli of both sexes photographed from different perspectives in a bisection task. In line with current findings, we report a significant overestimation of angry compared to neutral face stimuli that was modulated by face direction. Moreover, the perceived duration of sad face stimuli did not differ from that of neutral faces and was not influenced by face direction. Furthermore, we found that faces of the opposite sex appeared to last longer than those of the same sex. This outcome is discussed with regards to stimulus parameters like the induced arousal, social relevance and an evolutionary context.

The system introduced in this thesis is based on a 3D generative face model. Using a 3D model makes it possible to edit the face in the semantic space of pose, expression, and identity instead of pixel space, and due to its 3D nature allows...

  18. Managing water resources infrastructure in the face of different values

    Science.gov (United States)

    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.

  19. Series 'Facing Radiation'. 2 Facing radiation is facing residents

    The series is to report how general people, who are not at all radiological experts, have faced and understood the problems and tasks of radiation given by the Fukushima Daiichi Nuclear Power Plant Accident (Mar. 2011). The section 2 is reported by an officer of Date City, which localizes at 60 km northern west of the Plant, borders on Iitate Village of Fukushima prefecture, and is indicated as the important area of contamination search (IACS), which the reporter has been conducted for as responsible personnel. In July 2011, the ambient dose was as high as 3.0-3.5 mc-Sv/h and the tentative storage place of contaminated materials was decided by own initiative of residents of a small community, from which the real decontamination started in the City. The target dose after decontamination was defined to be 1.0 mc-Sv/h: however, 28/32 IACS municipalities in the prefecture had not defined the target although they had worked for 2 years after the Accident for their areas exceeding the standard 0.23 mc-Sv/h. At the moment of decontamination of the reporter's own house, he noticed that resident's concerns had directed toward its work itself, not toward the target dose, and wondered if these figures had obstructed to correctly face the radiation. At present that about 2.5 years have passed since the Accident, all of Date citizens have personal accumulated glass dosimeters for seeing the effective external dose and it seems that their dose will not exceed 1 mSv/y if the ambient dose estimated is 0.3-5 mc-Sv/h. Media run to popularity not to face radiation, experts tend to hesitate to face media and residents, and radiation dose will be hardly reduced to zero, despite that correct understanding of radiation is a shorter way for residents' own ease: facing radiation is facing residents.

    Individuals are embedded in social networks in which they communicate with others in their daily lives. Because smooth face-to-face communication is the key to maintaining these networks, measuring the smoothness of such communication is an important issue. One indicator of smoothness is the similarity of the body movements of the two individuals concerned. A typical example noted in experimental environments is the interpersonal synchronization of body movements such as nods and gestures during smooth face-to-face communication. It should therefore be possible to estimate quantitatively the smoothness of face-to-face communication in social networks through measurement of the synchronization of body movements. However, this is difficult because social networks, which differ from disciplined experimental environments, are open environments for the face-to-face communication between two individuals. In such open environments, their body movements become complicated by various external factors and may follow unstable and nonuniform patterns. Nevertheless, we consider there to be some interaction during face-to-face communication that leads to the interpersonal synchronization of body movements, which can be seen through the interpersonal similarity of body movements. The present study aims to clarify such interaction in terms of body movements during daily face-to-face communication in real organizations of more than 100 people. We analyzed data on the frequency of body movement for each individual during face-to-face communication, as measured by a wearable sensor, and evaluated the degree of interpersonal similarity of body movements between two individuals as their frequency difference. Furthermore, we generated uncorrelated data by resampling the data gathered and compared these two data sets statistically to distinguish the effects of actual face-to-face communication from those of the activities accompanying the communication. Our results confirm an
