    Examines in detail the role of innovative radiation techniques in the management of prostate cancer, including IMRT, IGRT, BART, and modern brachytherapy. Explores a range of current controversies in patient treatment. Intended for both radiation oncologists and urologists. Radiation treatment is rapidly evolving owing to the coordinated research of physicists, engineers, computer and imaging specialists, and physicians. Today, the arsenal of ''high-precision'' or ''targeted'' radiotherapy includes multimodal imaging, in vivo dosimetry, Monte Carlo techniques for dose planning, patient immobilization techniques, intensity-modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT), biologically adapted radiotherapy (BART), quality assurance methods, novel methods of brachytherapy, and, at the far end of the scale, particle beam radiotherapy using protons and carbon ions. These approaches are like pieces of a puzzle that need to be put together to provide the prostate cancer patient with high-level optimized radiation treatment. This book examines in detail the role of the above-mentioned innovative radiation techniques in the management of prostate cancer. In addition, a variety of current controversies regarding treatment are carefully explored, including whether prophylactic treatment of the pelvic lymphatics is essential, the magnitude of the effect of dose escalation, whether a benefit accrues from hypofractionation, and what evidence exists for the superiority of protons or heavy ions. Radiotherapy in Prostate Cancer: Innovative Techniques and Current Controversies is intended for both radiation oncologists and urologists with an interest in the up-to-date capabilities of modern radiation oncology for the treatment of prostate cancer.

    Full Text Available Max Uhle (1856-1944 and Julio Tello (1880-1947 made prominent contributions to the development of Peruvian archaeology in the first half of the 20th century, coinciding at some points and differing in others. Their contrasting academic proposals were linked to political positions, which in turn impacted the way of imagining the development of Peruvian archaeology. The article analyzes how the interdependence in the characterizations of Uhle and Tello led to the formation of a mirrored logic, placing them in two poles that condense positive and negative assessments, respectively. Finally, we explore the passage from the opposition of both figures to the construction of exclusive and nationality-dependent ways of doing research.

  10. Controversies surrounding authorship of manuscripts by industry employees: academic and industry perspectives.

    Science.gov (United States)

    Smilowitz, Nathaniel R; Ferguson, James J; Weisz, Giora

    2018-03-20

    The medical device and pharmaceutical industries play an essential role in the development of cardiovascular devices and drugs, and industry employees are frequently listed as co-authors of clinical trials published in peer-reviewed journals. Potential conflicts of interest in biomedical research have attracted significant attention in recent years, but issues and challenges surrounding authors who are industry employees have not received nearly as much scrutiny. We present a comprehensive discussion of the concerns and challenges regarding the role of industry in the authorship of scientific manuscripts. Academic co-authors, industry employees, the editors of medical journals, and, most importantly, readers, need to consider the perception and implications that accompany industry employee authorship. Potential concerns include the effect of industry authors (and industry support) on study design, data analysis, interpretations, conclusions, and, ultimately, scientific content. Meaningful contributions from industry employees must be acknowledged and reported in scientific and clinical publications. Efforts to provide full transparency on industry support and the role of industry contributors are necessary to maintain confidence in the reports of studies with industry involvement.

    Rosser, B R Simon; Kilian, Gunna; West, William G

    2013-03-01

    Certain research topics - including studies of sexual behavior, substance use, and HIV risk -- are more likely to be scrutinized by the media and groups opposed to this area of research. When studying topics that others might deem controversial, it is critical that researchers anticipate potential negative media events prior to their occurrence. By developing an Emergency Public Relations Protocol at the genesis of a study, researchers can identify and plan for events that might result in higher scrutiny. For each identified risk, a good protocol details procedures to enact before, during and after a media event. This manuscript offers recommendations for developing a protocol based on both Situational Crisis Communication Theory and our experience as an HIV prevention research group who recently experienced such an event. The need to have procedures in place to monitor and address social media is highlighted.

  7. Screening Out Controversy: Human Genetics, Emerging Techniques of Diagnosis, and the Origins of the Social Issues Committee of the American Society of Human Genetics, 1964-1973.

    Science.gov (United States)

    Mitchell, M X

    2017-05-01

    In the years following World War II, and increasingly during the 1960s and 1970s, professional scientific societies developed internal sub-committees to address the social implications of their scientific expertise (Moore, Disrupting Science: Social Movements, American Scientists, and the Politics of the Military, 1945-1975. Princeton: Princeton University Press, 2008). This article explores the early years of one such committee, the American Society of Human Genetics' "Social Issues Committee," founded in 1967. Although the committee's name might suggest it was founded to increase the ASHG's public and policy engagement, exploration of the committee's early years reveals a more complicated reality. Affronted by legislators' recent unwillingness to seek the expert advice of human geneticists before adopting widespread neonatal screening programs for phenylketonuria (PKU), and feeling pressed to establish their relevance in an increasingly resource-scarce funding environment, committee members sought to increase the discipline's expert authority. Painfully aware of controversy over abortion rights and haunted by the taint of the discipline's eugenic past, however, the committee proceeded with great caution. Seeking to harness interest in and assert professional control over emerging techniques of genetic diagnosis, the committee strove to protect the society's image by relegating ethical and policy questions about their use to the individual consciences of member scientists. It was not until 1973, after the committee's modest success in organizing support for a retrospective public health study of PKU screening and following the legalization of abortion on demand, that the committee decided to take a more publicly engaged stance.

  11. Predicting the academic success of architecture students by pre-enrolment requirement: using machine-learning techniques

    Directory of Open Access Journals (Sweden)

    Ralph Olusola Aluko

    2016-12-01

    Full Text Available In recent years, there has been an increase in the number of applicants seeking admission into architecture programmes. As expected, prior academic performance (also referred to as pre-enrolment requirement is a major factor considered during the process of selecting applicants. In the present study, machine learning models were used to predict academic success of architecture students based on information provided in prior academic performance. Two modeling techniques, namely K-nearest neighbour (k-NN and linear discriminant analysis were applied in the study. It was found that K-nearest neighbour (k-NN outperforms the linear discriminant analysis model in terms of accuracy. In addition, grades obtained in mathematics (at ordinary level examinations had a significant impact on the academic success of undergraduate architecture students. This paper makes a modest contribution to the ongoing discussion on the relationship between prior academic performance and academic success of undergraduate students by evaluating this proposition. One of the issues that emerges from these findings is that prior academic performance can be used as a predictor of academic success in undergraduate architecture programmes. Overall, the developed k-NN model can serve as a valuable tool during the process of selecting new intakes into undergraduate architecture programmes in Nigeria.

    The energy debate raises deep controversies, as discussions on climate change or electricity markets' deregulation show. In this context, it is very difficult for the citizen to express himself in referendums and for the decision maker to slice between various options. Experts themselves deliver controversial evaluations and interest groups can benefit from them to suggest their own solution. This book enables to get a better insight and better understand energy-related controversies and the environmental and socio-economic impacts of energy. It deals with topics as complex and politically extreme as the exhaustion of fossil fuels, climate change, ionising radiations, renewable energy sources, energy consumption in Southern countries and the reorganisation of electricity markets. It starts with an article on the precaution principle and it ends with a glance on the future, devoted to education in the field of efficient energy use [fr

    2008-04-22

    During the last two decades, medical education in Iran has shifted from elite to mass education, with a considerable increase in number of schools, faculties, and programs. Because of this transformation, it is a good case now to explore academic leadership in a non-western country. The objective of this study was to explore the views on effective academic leadership requirements held by key informants in Iran's medical education system. A nominal group study was conducted by strategic sampling in which participants were requested to discuss and report on requirements for academic leadership, suggestions and barriers. Written notes from the discussions were transcribed and subjected to content analysis. Six themes of effective academic leadership emerged: 1)shared vision, goal, and strategy, 2) teaching and research leadership, 3) fair and efficient management, 4) mutual trust and respect, 5) development and recognition, and 6) transformational leadership. Current Iranian academic leadership suffers from lack of meritocracy, conservative leaders, politicization, bureaucracy, and belief in misconceptions. The structure of the Iranian medical university system is not supportive of effective academic leadership. However, participants' views on effective academic leadership are in line with what is also found in the western literature, that is, if the managers could create the premises for a supportive and transformational leadership, they could generate mutual trust and respect in academia and increase scientific production.

  19. High school students' science academic achievement: The effect of the Lemov positive framing trust-building technique

    Science.gov (United States)

    Gigliette, Linda Marie

    The purpose of this research was to investigate the effect of a trust-building technique called "positive-framing" (Lemov, 2010, p. 204) on the level of student-teacher trust and students' science academic achievement. The existing literature was reviewed under the constructs of trust, types of trust, trust-building strategies, and student academic achievement. The identified problem is a lack of research into the effect of trust from the high school student perspective and the effect of trust on student academic achievement in science. In addition, there is no empirical evidence to support the effectiveness of the "positive-framing" (Lemov, 2010, p. 204) trust-building intervention. The study involved a volunteer, convenience sample of 9th-grade science students at one high school in Northern California (N=240). The study employed a quasi-experimental, pretest, posttest non-equivalent control group design to examine the level of student trust in the teacher, using the "Student trust in faculty scale" (Forsyth, Adams, & Hoy, 2011, p. 180), and the students' academic achievement, according to the Integrated Process Skills Test II (Okey, Wise, & Burns, 1982). The independent variable was the "positive-framing" (Lemov, 2010, p. 204) trust-building intervention; the two dependent variables were the level of student-teacher trust and student academic achievement. The composite data from the "Student trust in faculty scale" and the academic achievement test were evaluated by a multivariate analysis of covariance (MANCOVA). Results of this study indicated that the null hypothesis was accepted. The "positive-framing" (Lemov, 2010, p. 204) trust-building intervention did not have a significant effect on either the student-teacher trust level or academic achievement in science.

Despite well-documented associations, controversial messages on causes of cancer often appear without taking into consideration their impact on the general population. While mainstream coverage of cancer research is clearly welcome, consideration must be given to the risk of transmitting provocative messages with serious negative consequences for cancer research and public health. We must avoid becoming a breeding ground for the misinterpretation of scientific information. Polemical results can stimulate scientific research and progress, but controversial messages encourage confusion and impotence in an increasingly disoriented population. The correct communication of health messages is at least as important as research on risk factors.

  4. The Thimerosal Controversy

    OpenAIRE

    Sutherland, Aimee

    2013-01-01

    Historically, there has always been a degree of concern related to vaccination. While public health policy in the early 1900s was more concerned with the contamination of vaccine vials with microbes, such as tetanus, that could cause serious illness and potentially death, current vaccination concerns are centered on the apprehension of chemicals ‘contaminating’ vaccines. The modern day vaccination controversy regarding chemical contamination began as a result of environmental concerns regardi...

Some of the epidemiologic and technical issues include ascertainment and reporting of cases, case definition and laboratory confirmation, identification and purification of antigens, vaccine potency measurement, vaccine efficacy, and vaccine safety. Other factors include legal and economic issues, ethical concerns, emotional overlays, an...

  6. Controversies in Obesity Treatment

    Directory of Open Access Journals (Sweden)

    Majid Karandish

    2015-06-01

    Full Text Available The markedly high prevalence of obesity contributes to the increased incidence of chronic diseases, such as diabetes, hypertension, sleep apnea, and heart disease. Because of high prevalence of obesity in almost all countries, it has been the focus of many researches throughout the world during the recent decades. Along with increasing researches, new concepts and controversies have been emerged. The existing controversies on the topic are so deep that some researches argue on absolutely philosophical questions such as “Is obesity a disease?” or “Is it correct to treat obesity?” These questions are based on a few theories and real data that explain obesity as a biological adaptation and also the final results of weight loss programs. Many people attempt to lose weight by diet therapy, physical activity and lifestyle modifications. Importantly, weight loss strategies in the long term are ineffective and may have unintended consequences including decreasing energy expenditure, complicated appetite control, eating disorders, reducing self-esteem, increasing the plasma and tissue levels of persistent organic pollutants that promote metabolic complications, and consequently, higher risk of repeated cycles of weight loss and weight regain. In this review, major paradoxes and controversies on obesity including classic obesity paradox, pre-obesity; fat-but-fit theory, and healthy obesity are explained. In addition, the relevant strategies like “Health at Every Size” that emphasize on promotion of global health behaviors rather than weight loss programs are explained.

  9. Simulation of energy saving potential of a centralized HVAC system in an academic building using adaptive cooling technique

    International Nuclear Information System (INIS)

    Bhaskoro, Petrus Tri; Gilani, Syed Ihtsham Ul Haq; Aris, Mohd Shiraz

    2013-01-01

    Highlights: • We have simulated and validated the cooling loads of a multi-zone academic building, in a tropical region. • We have analyzed the effect of occupancy patterns on the cooling loads. • Adaptive cooling technique has been utilized to minimize the energy usage of HVAC system. • The results are promising and show a reduction of energy saving in the range of 20–30%. - Abstract: Application of adaptive comfort temperature as room temperature set points potentially reduce energy usage of the HVAC system during a cooling and heating period. The savings are mainly due to higher indoor temperature set point during hot period and lower indoor temperature set point during cold period than the recommended value. Numerous works have been carried out to show how much energy can be saved during cooling and heating period by applying adaptive comfort temperature. The previous work, however, focused on a continuous cooling load as found in many office and residential buildings. Therefore, this paper aims to simulate the energy saving potential for an academic glazed building in tropical Malaysian climate by developing adaptive cooling technique. A building simulation program (TRNSYS) was used to model the building and simulate the cooling load characteristic using current and proposed technique. Two experimental measurements were conducted and the results were used to validate the model. Finally, cooling load characteristic of the academic building using current and proposed technique were compared and the results showed that annual energy saving potential as much as 305,150 kW h can be achieved

  12. The nuclear controversy and nuclear safety techniques

    International Nuclear Information System (INIS)

    Ragnarson, P.

    1979-09-01

    Survey interviews with 125 Swedish nuclear safety engineers are summarized and commented upon. A short historical background is given, claiming that the major safety issues of nuclear energy have been debated continously during the 50's and 60's in a way that could well have been watched and interpreted by a political, democratic system involving political parties, government departments, etc. With a few exceptions, these 125 engineers represent 10 - 20 years experience in nuclear research and development. By definition they belong to a professional group of about 800 in Sweden (1978). The main aim of the study is to find out if (how and why) a public debate can bring about changes in an industrially established technology by influencing the attitudes and technical judgements of the individuals and/or organizations involved. Examples are given in which the nuclear specialists themselves admit or claim that direct or indirect impacts from the public debate have been important. A common experience is that the scientists and engineers have been forced to broaden their professional scope through a time-consuming but - on the whole - 'positive' process. A year after the interviews started, a serious reactor accident occured near Harrisburg, Pennsylvania. The group has been used for a survey of the immediate reactions in order to see if it could cause sudden changes of attitudes among the experts. A minority demonstrated clear changes towards a more cautious attitude regarding nuclear risks. (author)

  13. Siting controversial facilities

    Baird, R.D.; Blacker, P.B.

    1985-01-01

    There is often significant difficulty involved with siting controversial facilities. The social and political problems are frequently far more difficult to resolve than the technical and economic issues. The tendancy for most developing organizations is to address only technical issues in the search for a technically optimal site, to the exclusion of such weighting considerations as the social and political climate associated with potential sites--an approach which often imperils the success of the project. The site selection processes currently suggested is summarized and two contemporary examples of their application are cited. The difference between developers' real objectives and the objectives they have implicitly assumed by adopting the recommended approaches without augmentation are noted. The resulting morass of public opposition is attributed to the failure to consider the needs of individuals and groups who stand to be negatively impacted by the development. A comprehensive implementation strategy which addresses non-technical consideration in parallel with technical ones is presented and evaluated

    Thomashow, M.S.

    1986-01-01

    This dissertation articulates elements of an educational strategy derived from the experience of the KNOW NUKES program, a teacher training project designed to introduce the nuclear power controversy in the high school classroom. This strategy can be used as means of furthering the effectiveness of controversial issues education, not only in the area of nuclear power, but in teaching about any environmental issue. This is specifically achieved by (2) placing the KNOW NUKES institute in the broader context of controversial issues education; (2) describing in detail KNOW NUKES project planning; (3) reviewing the structure and content of the various teaching techniques and materials that have been developed for the KNOW NUKES institute; (4) utilizing a particular technique developed by the institute that reveals varying perspectives on controversial issues, in this case, an instrumental for decoding the controversial issues that are explicit and implicit in corporate image advertisements; and (5) qualitatively evaluating the practical implementation of the KNOW NUKES model

The area of the hand with a proper antiseptic distribution was the palm (92.9%; areas not properly scrubbed were the thumbs (55.1%. 24.7% was very good in both hands, 29.8% was good, 25.1% was fair, and 20.3% was poor. The worst assessed were the male, nursing and first year students. There were no significant differences in the age groups.Conclusions: hand hygiene technique is not applied efficiently. Education plays a key role in setting a good practice base in hand hygiene, theoretical knowledge, and in skill development, as well as good practice reinforcement.

    Mini gastric bypass is a modification of Mason loop gastric bypass with a longer lesser curvature-based pouch. Though it has been around for more than 15 years, its uptake by the bariatric community has been relatively slow, and the procedure has been mired in controversy right from its early days. Lately, there seems to be a surge in the interest in this procedure, and there is now published experience with more than 5,000 procedures globally. This review examines the major controversial aspects of this procedure against the available scientific literature. Surgeons performing this procedure need to be aware of these controversies and counsel their patients appropriately.

  2. Silicosis: controversy in detection

    2014-03-01

    Full Text Available In many countries, the work of mining, quarrying, construction of tunnels and galleries, abrasive jet cleaning and smelting continue to present significant risks of silica exposure and silicosis epidemics still occur, even in developed countries. Patients with silicosis are particularly susceptible to opportunistic lung infections such as aspergillosis and tuberculosis. Occasionally silicosis is associated with scleroderma, systemic lupus erythematosus, nephritis and cancer. Early detection of silicosis is made by chest X-ray method, being the presence of rounded opacities the main sign of illness. However, no systematic information is available that allows use as a standard method of evaluation because their interpretation remains operator dependent both conventional radiological technique, digital and interpretation of computed tomography with high resolution.

    Bioethics and the public debate is certainly a nonsense for those who still believe that medical practice should only be a matter of individual relationship between a physician and his/her patient, such a relationship being regulated by the awareness that the medical practitioner has of his/her ethical duties. However for those who believe that physicians and other health care providers cannot find any more the replies to the problems raised by the development of new biomedical techniques in their own professional ethics, at least three questions should be posed. Can the traditional democratic institutions face those issues? Is there a need for new institutions to be built? Are such mechanisms--both old and new--appropriate to support a public debate?

    2016-09-01

    SummaryOngoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings-and scientific truths-about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation-that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however. © The Author(s) 2016.

    Full Text Available The use of software identifying text coincidences instruments provides an analysis of scientific and academic works for the evidence of plagiarism. Besides, the anti-plagiarism is not just a fight against illegal text borrowings as consequences of this phenomenon. It should be a comprehensive mechanism for dealing with both the consequences and the causes of the appearance of such a phenomenon. Such mechanism should include the implementation of the system of values that correspond to the principles of academic integrity, along with making total enquiries of all works on plagiarism. The exhaustive list of text borrowings, which is resultant, is the basis for expertsassessors decision-making in point of plagiarism presence. What is more, there should be no permissible standards of the plagiarism. All borrowings must being drawn up in accordance with the requirements. Therefore, the best result in the fight against plagiarism will achieved only by comprehensive approach – when the academic culture and the principles of academic integrity will be instilled ever since school, along with the check of all works for plagiarism.

    2001-09-01

    Military laser weapons systems are becoming indispensable in most modern armies. These lasers have undergone many stages of development, and have outpaced research on eye protection measures, which continue to have inherent limitations. Eye injuries caused by military lasers are increasingly reported, leading to speculation that these would become an important cause of blinding in modern conflicts. As part of the effort to ban inhumane weapons, international laws have been passed to restrict the proliferation of such blinding weapons. However, there are controversies concerning the interpretation, implementation and effectiveness of these laws. The ophthalmic community can play a greater role in highlighting ocular morbidity from military lasers, and in preventing their further proliferation.

  3. Current controversies in childhood vaccination.

    2013-01-01

    As pediatric practitioners, one of the contemporary challenges in providing medical care for children is the increasing proportion of vaccination refusal. This occurs in spite of the demonstrated individual and collective benefit and cost effectiveness of vaccination. Controversies regarding vaccine components and side effects have misled parents to believe that vaccines might be harmful based on inaccurate data from the Internet, celebrities, as well as misinterpreted and frankly bad science. This belief of vaccines being harmful has led to fear and decreased immunization rates in spite of sound scientific evidence supporting the safety of vaccines and their lack of association with autism, developmental disabilities or other medical disorders. Some parents also believe in alternative ways to avoid disease, often adhering to practices that have little foundation in the best of empiric science. It is not a coincidence that recent outbreaks of vaccine-preventable diseases, including measles and pertussis (whooping cough), have occurred in areas where vaccination has declined largely due to exemptors. This article intends to review some of the common vaccine myths and controversies and to serve as a resource to provide accurate information and references for busy practitioners and the families that we serve.

  5. Metaphysics for an enlightened public: The controversy over monads in Germany, 1746-1748.

    Science.gov (United States)

    Broman, Thomas

    2012-03-01

    This essay analyzes the controversy that attended the prize essay question on monads proposed by the Berlin Academy of Sciences in 1746. The controversy was first touched off by an anonymous pamphlet published by the mathematician Leonhard Euler, the academy's most well known member, that attacked the doctrine of monads. It peaked with the awarding of the prize to Johann Heinrich Gottlob Justi, whose winning essay closely followed Euler's arguments. This essay discusses the controversy as one instance in a broader quarrel in the German academic community over the suitability of Christian Wolff's philosophy as the foundation for a broad range of academic disciplines, including natural philosophy. It also analyzes the controversy as displaying the central role of the periodical press in the emergent German public sphere.

    This research investigates the controversies that emerge in the fuzzy front end (FFE) and how they are closed so the innovation process can move on. The fuzzy front has been characterized in the literature as a very critical phase, but controversies in the FFE have not been studied before....... The analysis investigates the microprocesses around the controversies that emerge during the fuzzy front end of four products. Five different types of controversies are identified: profit, production, design, brand and customers/market. Each controversy represents a threat, but also an opportunity to search...... demonstrates how the fuzzy front requires managers to deal with controversies that emerge from many different places and involve both human and non-human actors. Closing the controversies requires managers to take account of the situation, identify the problem that needs to be addressed, and initiate a search...

  8. Darwinian Controversies: An Historiographical Recounting

    Science.gov (United States)

    Depew, David J.

    2010-05-01

    This essay reviews key controversies in the history of the Darwinian research tradition: the Wilberforce-Huxley debate in 1860, early twentieth-century debates about the heritability of acquired characteristics and the consistency of Mendelian genetics with natural selection; the 1925 Scopes trial about teaching evolution; tensions about race, culture, and eugenics at the 1959 centenary celebration Darwin’s Origin of Species; adaptationism and its critics in the Sociobiology debate of 1970s and, more recently, Evolutionary Psychology; and current disputes about Intelligent Design. These controversies, I argue, are etched into public memory because they occur at the emotionally charged boundaries between public-political, technical-scientific, and personal-religious spheres of discourse. Over most of them falls the shadow of eugenics. The main lesson is that the history of Darwinism cannot be told except by showing the mutual influence of the different norms of discourse that obtain in the personal, technical, and public spheres. Nor can evolutionary biology successfully be taught to citizens and citizens-to-be until the fractious intersections between spheres of discourse have been made explicit. In the course of showing why, I take rival evolutionary approaches to be dynamical historical research traditions rather than static theories. Accordingly, I distinguish Darwin’s version of Darwinism from its later transformations. I pay special attention to the role Darwin assigned to development in evolution, which was marginalized by twentieth-century population genetical Darwinism, but has recently resurfaced in new forms. I also show how the disputed phrases “survival of the fittest” and “social Darwinism” have shaped personal anxieties about “Darwinism,” have provoked public opposition to teaching evolution in public schools, and have cast a shadow over efforts to effectively communicate to the public largely successful technical efforts to make

  9. Behavioural controversy concerning homo economicus: a Humean perspective

    2014-05-01

    Full Text Available In his monumental masterpiece, A Treatise on Human Nature, which explains the methodology of human reasoning concerning matters of fact and describes the roles that passions and morals play in it, Hume arrives at an enormously interesting maxim: An academic controversy cannot continue for long unless the disputants assign different meanings to the major terms employed in the debate. This theory has been applied in this paper to examine the behavioural criticisms about Homo Economicus (HE, the pivotal perception in the neoclassical microeconomic model.To achieve this objective, the paper discusses the origin and evolution of the concept, reviews behavioural criticisms, summarises the main tenets of Hume’s philosophy of human knowledge and finally examines the behavioural opinions from Hume’s perspective. The paper concludes that Hume’s theory convincingly explains the reason why the HE controversy is continuing for over half century- a fact that both the mainstream and behavioural economists are ignoring.

  10. The HPV vaccine mandate controversy.

    Haber, Gillian; Malow, Robert M; Zimet, Gregory D

    2007-12-01

    In this editorial we address the controversies surrounding human papillomavirus (HPV) vaccine school-entry mandate legislation, but differentiate between the mandate debate and issues specific to the vaccine itself. Our goal is not to take a stand in favor of or opposed to mandates, but rather to critically examine the issues. We discuss the following arguments against HPV vaccine school-entry requirements: 1. The public health benefit of mandated HPV vaccination is not sufficient to warrant the intrusion on parental autonomy; 2. A vaccine that prevents a non-casually transmitted infection should not be mandated; 3. Opt-out provisions are inherently unfair to parents who oppose HPV vaccination; 4. Limited health care dollars should not be directed toward cervical cancer prevention; and 5. The vaccine is expensive and potential problems with supply suggest that mandates should not be implemented until insurance coverage and supply issues are resolved. Next, we critically evaluate the following critiques of HPV vaccination itself: 1. Giving girls HPV vaccine implies tacit consent to engage in sexual activity; 2. Giving girls this vaccine will confer a false sense of protection from sexually transmitted infections and will lead to sexual disinhibition; 3. Children already have too many vaccinations on the immunization schedule; 4. Long-term side effects of HPV vaccine are unknown; 5. The vaccine's enduring effectiveness is unknown and booster shots may be required; and 6. It is wrong to only target girls with HPV vaccine; boys should be vaccinated as well.

  11. Lyme disease: why the controversy?

    Some Australians have become convinced of the existence of locally acquired Lyme disease (LD). The history of LD, since its recognition in the early 1970s, is reviewed as a model for investigative approaches to unknown syndromes. Australian Management Guidelines for LD include the requirement for diagnostic testing by National Association of Testing Authorities-accredited laboratories using Therapeutic Goods Administration-licensed tests, which result in the efficient diagnosis of LD in overseas travellers. Despite this, patients who have not left Australia pay many thousands of dollars for non-specialist consultations and testing at overseas laboratories. Unproven long-term therapy with multiple antibiotics has resulted in serious complications, including allergies, line sepsis, pancreatitis and pseudomembranous colitis. Studies have shown that LD vectors are not found in Australia, and Lyme Borrelia has not been found in Australian vectors, animals or patients with autochthonous illnesses. I propose that (i) A non-controversial name for the chronic syndrome should be adopted, 'Australian Multisystem Disorder'. (ii) Research funding should enable the development of a consensus case definition and studies of the epidemiology of this syndrome with laboratory investigations to identify an aetiology and surrogate markers of disease. Prospective, randomised treatment studies could then be undertaken using ethical protocols. © 2016 Royal Australasian College of Physicians.

  12. HPV vaccines: a controversial issue?

    Directory of Open Access Journals (Sweden)

    A.F. Nicol

    2016-01-01

    Full Text Available Controversy still exists over whether the benefits of the available HPV vaccines outweigh the risks and this has suppressed uptake of the HPV vaccines in comparison to other vaccines. Concerns about HPV vaccine safety have led some physicians, healthcare officials and parents to withhold the recommended vaccination from the target population. The most common reason for not administering the prophylactic HPV vaccines are concerns over adverse effects. The aim of this review is the assessment of peer-reviewed scientific data related to measurable outcomes from the use of HPV vaccines throughout the world with focused attention on the potential adverse effects. We found that the majority of studies continue to suggest a positive risk-benefit from vaccination against HPV, with minimal documented adverse effects, which is consistent with other vaccines. However, much of the published scientific data regarding the safety of HPV vaccines appears to originate from within the financially competitive HPV vaccine market. We advocate a more independent monitoring system for vaccine immunogenicity and adverse effects to address potential conflicts of interest with regular systematic literature reviews by qualified individuals to vigilantly assess and communicate adverse effects associated with HPV vaccination. Finally, our evaluation suggests that an expanded use of HPV vaccine into more diverse populations, particularly those living in low-resource settings, would provide numerous health and social benefits.

This case, however, challenges some established...... conventions within securitization theory.

    Unruptured intracranial aneurysms (UIAs) are being detected and treated with endovascular techniques at an increasing rate, with little evidence on the optimal imaging follow-up protocol. We performed a survey of academic neurovascular centers in the United States to assess imaging follow-up strategies and costs after endovascular treatment of UIAs. An online survey on 5-year follow-up strategies of UIAs treated with endovascular techniques was distributed to neurovascular directors of 101 academic neurovascular centers using the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Cerebrovascular Section database. An online healthcare marketplace, NewChoiceHealth, was used to calculate costs. Of 33 (32.7%) institutions that responded to the survey, 26 (25.7%) provided data suitable for analysis. Nine (34.6%), 10 (38.5%), 4 (15.4%), and 3 (11.5%) centers were located in the northeastern, southern, midwestern, and western regions of the United States. Total costs of 5-year follow-up imaging after primary coil embolization and stent-assisted coiling procedures were $3391-$32,882. Costs for aneurysms treated with flow diversion were $2788-$46,670. Eighteen (69.2%) institutions performed cerebral angiography at 6-month follow-up after coil embolization and stent-assisted coiling, and 19 (73.1%) institutions performed cerebral angiography 6 months after flow diversion. Of institutions, 20% affirmed that they maintained an identical imaging follow-up regimen after treatment of ruptured aneurysms. There is significant heterogeneity in imaging follow-up strategies and their associated costs. Stratification of patients by risk of recanalization and corresponding adjustment of follow-up imaging may be 1 strategy to limit unnecessary imaging and control costs. Copyright © 2016 Elsevier Inc.

    2013-11-01

    Ever since its development in 1937, the live-attenuated 17D yellow fever (YF) vaccine has been one of the most effective vaccines available to man. In this review we highlight the major steps in the development of 17D YF vaccine. We discuss the use of neutralizing antibodies as a surrogate marker for protection, and explore the strengths and weaknesses of the current plaque reduction neutralization test (PRNT), a technique developed in the 1960s that continues to be superior to every modern test in both sensitivity and specificity. The neutralizing antibodies demonstrated by the PRNT can be detected for several decades after vaccination, possibly even for the remainder of the recipient's natural life. We review the available evidence on the duration of protection after primary vaccination, a topic that has been the subject of controversy over the last few months. For persons who are immunocompromised due to disease, medication or advancing age, the duration of protection may be shorter: they should always have their vaccine response checked by PRNT. Due to the higher risk of severe adverse events after vaccination with 17D YF in this group, the development of a new, inactivated vaccine will have substantial benefits in this population.

  3. Predicting Public Acceptability in Controversial Technologies

    International Nuclear Information System (INIS)

    Bruce, Donald M.

    2003-01-01

    Technology and society have a synergic relationship. New technologies are a product of the values and aspirations of the culture in which they emerge. In turn, each new technology shapes and alters these values and aspirations, to a greater or lesser degree. The acceptance by society of any particular technology depends, however, on how far the values embodied in the technology reflect those of the wider society, or only those of some privileged sector - perhaps a ruling elite, a group of academic researchers, a commercial company, or even a special interest group. As public disquiet about controversial technologies has grown, their acceptance can no longer be taken for granted. It is now becoming more important to evaluate in advance the degree of likely mismatch between the aspirations of the technologists and the values of society. This paper explores one approach to making this evaluation, based on the notion of a conditional social contract between technology and society. A given society may be prepared to embrace a new technology to deliver certain benefits, and may accept a certain degree of risk and adaptation of life styles, provided certain basic conditions are fulfilled. These conditions include the upholding of basic values, familiarity, how it compares with similar technologies, the degree of control and choice, trust in those in control, the nature of any risks, the tangible benefits, and the media profile given to the new area. If several of these factors are not fulfilled, the technology is unlikely to be accepted. This was dramatically illustrated in the UK public reaction to food products derived from imported US GM soya and maize. These failed nearly all the conditions, so that public rejection should have been seen as a foregone conclusion. In the light of this, the likely public reaction to a number of future biotechnological innovations is assessed, based on the same conditions. Some examples taken from the energy sector are also compared. The

    The physical characteristics of proton beams are appealing for cancer therapy. The rapid increase in operational and planned proton therapy facilities may suggest that this technology is a "plug-and-play" valuable addition to the arsenal of the radiation oncologist and medical physicist. In reality, the technology is still evolving, so planning and delivery of proton therapy in patients face many practical challenges. This review article discusses the current status of proton therapy treatment planning and delivery techniques, indicates current limitations in dealing with range uncertainties, and proposes possible developments for proton therapy and supplementary technology to try to realize the actual potential of proton therapy.

  7. How science makes environmental controversies worse

    International Nuclear Information System (INIS)

    Sarewitz, Daniel

    2004-01-01

    I use the example of the 2000 US Presidential election to show that political controversies with technical underpinnings are not resolved by technical means. Then, drawing from examples such as climate change, genetically modified foods, and nuclear waste disposal, I explore the idea that scientific inquiry is inherently and unavoidably subject to becoming politicized in environmental controversies. I discuss three reasons for this. First, science supplies contesting parties with their own bodies of relevant, legitimated facts about nature, chosen in part because they help make sense of, and are made sensible by, particular interests and normative frameworks. Second, competing disciplinary approaches to understanding the scientific bases of an environmental controversy may be causally tied to competing value-based political or ethical positions. The necessity of looking at nature through a variety of disciplinary lenses brings with it a variety of normative lenses, as well. Third, it follows from the foregoing that scientific uncertainty, which so often occupies a central place in environmental controversies, can be understood not as a lack of scientific understanding but as the lack of coherence among competing scientific understandings, amplified by the various political, cultural, and institutional contexts within which science is carried out. In light of these observations, I briefly explore the problem of why some types of political controversies become 'scientized' and others do not, and conclude that the value bases of disputes underlying environmental controversies must be fully articulated and adjudicated through political means before science can play an effective role in resolving environmental problems

  8. Techniques to Assess and Mitigate the Environmental Risk Posed by use of Airguns: Recent Advances from Academic Research Programs

    There is considerable uncertainty about the ways in which marine mammals might react to noise, the biological significance of reactions, and the effectiveness of planning and real-time mitigation techniques. A planning tool commonly used to assess environmental risk of acoustic activities uses simulations to predict acoustic exposures received by animals, and translates exposure to response using a dose-response function to yield an estimate of the undesired impact on a population. Recent advances show promise to convert this planning tool into a real-time mitigation tool, using Bayesian statistical methods. In this approach, being developed for use by the British Navy, the environmental risk simulation is updated continuously during field operations. The distribution of exposure, set initially based on animal density, is updated in real-time using animal sensing data or environmental data known to correlate with the absence or presence of marine mammals. This conditional probability of animal presence should therefore be more accurate than prior probabilities used during planning, which enables a more accurate and quantitative assessment of both the impact of activities and reduction of impact via mitigation decisions. Two key areas of uncertainty in addition to animal presence/absence are 1.) how biologically-relevant behaviours are affected by exposure to noise, and 2.) whether animals avoid loud noise sources, which is the basis of ramp-up as a mitigation tool. With support from MMS and industry partners, we assessed foraging behaviour and avoidance movements of 8 tagged sperm whales in the Gulf of Mexico during experimental exposure to airguns. The whale that was approached most closely prolonged a surface resting bout hours longer than typical, but resumed foraging immediately after the airguns ceased, suggesting avoidance of deep diving necessary for foraging near active airguns. Behavioral indices of foraging rate (echolocation buzzes produced during prey

    Slickwater high-volume hydraulic fracturing (commonly known as "fracking") is highly controversial. So is global warming, and the two issues are closely related, but the natures of these two controversies have substantial and important differences. Building upon years of experience in teaching and developing resources and strategies for teaching about evolution and climate change, staff at the Paleontological Research Institution have engaged in public outreach and educator professional development to help nurture understanding of fracking and the broader energy system. How are these controversies similar to and different from one another, and how should understanding these similarities and differences inform educational programming (and about how you talk about these issues with your Uncle Fred at the family holiday dinner?). It is nearly universally agreed amongst scientists who study climate that changes now underway are real and human caused, and are posing or likely to pose very serious problems for humanity. Scientists who study slickwater high-volume hydraulic fracturing agree that it causes environmental damage, but there is no consensus as to whether fracking causes more or less harm (e.g., among different kinds of environment harm, across different temporal and spatial scales, and among different social contexts) than other ways of producing energy on a large scale. In other words, the basic tenets of climate change are not a matter of scientific controversy, though the implications for policy making obviously remain politically controversial, while fracking is an issue of both scientific and political controversy. Without advocating for or against fracking, we help audiences disentangle scientific and political issues, better understand the energy resources used in their own communities, and consider issues of scale, systems, and complexity. We will compare and contrast the overlapping controversies surrounding climate change and fracking and highlight

    Chetouani, Lamria

    2007-01-01

    The author analyses the rhetorical staging of controversies which occur in France about climate change, and more particularly about the greenhouse effect. In a first part, she makes a distinction between four registers of controversy: on responsibilities, on consequences and extent of the phenomenon, on solutions, and on spatio-temporal projections of the greenhouse effect. She shows that debates are structured by an opposition between optimism and pessimism. In a second part, based on a lexicological analysis, she highlights the important oppositions between scientific speeches and political speeches, independent speeches and technocratic speeches, and so on, with unexpected aspects. It appears that controversy goes largely beyond the scientific debate, and incorporates crossed interventions of economic, political and social concern

It traces back the controversy to the past two decades, beginning in the late 1920s-birth of quantum theory-and concluding with Erwin Schroedinger's lectures published as 'Mind and Matter'. Becoming aware of the issues at stake can help us understand the historical, philosophical and cultural background from which today's physics emerged

  8. Unwaged Posts in UK Universities: Controversies and Campaigns

    Directory of Open Access Journals (Sweden)

    Kirsten Forkert

    2015-09-01

    Full Text Available This article examines unwaged posts at UK universities, using recent examples of advertised job posts. While unpaid work is common in the UK higher education system, unwaged posts are not. The posts under scrutiny in this article differ from traditional honorary titles as they target early career academics, who are unlikely to have a paid position elsewhere, rather than established scholars. The article contextualizes the appearance of these posts in a climate of increasing marketization of higher education, entrenching managerialism in higher education institutions, and the casualization of academic work. We also discuss resistance to the posts, arguing that the controversy surrounding unpaid internships in the creative industries created a receptive environment for resisting unwaged posts in academia. We analyze the campaigns that were fought against the advertisement of the posts, mostly through social media and the University and College Union. We explore the tactics used and discuss the advantages and limitations of the use of social media, as well as the role of trade unions in the campaigns against these posts, and we reflect on what future campaigns can learn from these experiences.

  13. Epistemic Authority and Genuine Ethical Controversies.

    Science.gov (United States)

    Roberts, Adam James

    2017-05-01

    In 'Professional Hubris and its Consequences', Eric Vogelstein claims that 'that there are no good arguments in favor of professional organizations taking genuinely controversial positions on issues of professional ethics'. In this response, I defend two arguments in favour of organisations taking such positions: that their stance-taking may lead to better public policy, and that it may lead to better practice by medical professionals. If either of those defences succeeds, then Vogelstein's easy path to his conclusion - that professional organisations should not take such stances - is blocked. He or others must instead look to establish that the reasons against stance-taking on genuine ethical controversies are more compelling than those for it: plausibly a more challenging task. © 2017 John Wiley & Sons Ltd.

  14. History of the Belgian nuclear power controversy

    International Nuclear Information System (INIS)

    Laes, E.

    2009-01-01

    Partly because nuclear energy technology continues to provoke profound controversy, the Flemish institute for technology assessment (viWTA) took the initiative to order a study aimed at mapping out the historical dynamics of the societal debate on nuclear energy. This study was carried out by the Belgian Nuclear Research Centre (SCK-CEN, under the research programme PISA) together with the Free university of Brussels (VUB, research group MEKO) in 2004. In 2007, the report was updated and published by Acco (Leuven) under the title Kernenergie (on)besproken. This study had three main objectives: 1) to discuss the societal debate on nuclear energy in Belgium in relation to major events (Chernobyl, TMI, etc.); 2) to elucidate the role of social actors in the controversy on both a national and international level and 3) to discuss possible alternatives for a better structuring of the debate in the future, building on existing approaches

  18. Metabolic effects of resveratrol: addressing the controversies.

    Science.gov (United States)

    Bitterman, Jacob L; Chung, Jay H

    2015-04-01

    Resveratrol, a polyphenol found in a number of plant-based foods such as red wine, has received a great deal of attention for its diverse array of healthful effects. Beneficial effects of resveratrol are diverse; they include improvement of mitochondrial function, protection against obesity and obesity-related diseases such as type-2 diabetes, suppression of inflammation and cancer cell growth and protection against cardiovascular dysfunction, just to name a few. Investigations into the metabolic effects of resveratrol are furthest along and now include a number of clinical trials, which have yielded mixed results. There are a number of controversies surrounding resveratrol that have not been resolved. Here, we will review these controversies with particular emphasis on its mechanism of metabolic action and how lessons from resveratrol may help develop therapies that harness the effects of resveratrol but without the undesirable properties of resveratrol.

  19. Controversies Concerning Theological Language: Cognitivity and Revelation

    Directory of Open Access Journals (Sweden)

    Mindaugas Briedis

    2011-04-01

    Full Text Available Theological language as a problem under research is especially a controversial one. The question of language enerpsrise is crucial if we are willing to concider theology as a rational and/or critical discipline despite its „object“ or „religious substance“ which can be defined as irrational in the sense of divine mistery. The reflection of a specific referential system which is constituted by theological propositions uncovers peculiar logic of theological language which in turn is always in correlation with basic shifts in philosophy. The paper questions this mutuality as well as presents several characteristic controversies in contemporary theology, particularly in the protestant one. After these goals are achieved, it is possible to formulate concluding  ideas about the problem of cognitive value of revelation, and, on the other hand, about the influence of concrete forms of knowledge (modern ontology for the structures of faith.

  1. Pertussis and Rotavirus Vaccines - Controversies and Solutions.

    Science.gov (United States)

    Dash, Nabaneeta; Verma, Sanjay

    2018-01-01

    Pertussis and rotavirus vaccines have been the subject of several controversies over the years. In this paper the authors discuss facts and myths behind these controversies and also suggest solutions to overcome some limitations of these vaccines. The whole-cell pertussis vaccine (wPV) came into disrepute due to the associated adverse reactions, resulting in its replacement by acellular pertussis vaccine (aPV) in industrialized nations in 1990s. Although wPV is known to have more side effects; but they are usually minor. Whole-cell pertussis containing vaccine is being used safely in the National Immunization programme in India from many years. Another controversy erupted during 2009-2010, when there were reports of resurgence of pertussis cases among adolescents and adults, from developed nations. Present literature review raises doubts about long term protection offered by aPV, when compared with wPV. In spite of prevailing controversy, acellular pertussis containing vaccines should be acceptable, if timely delivery of primary and booster doses is ensured; including vaccination of adolescents and pregnant women. Initial rotavirus vaccine was withdrawn from the market because of increased risk of intussusception. Although three new generation rotavirus vaccines are currently available for use in India, but doubts about their efficacy, long term protection and safety still exists. Present literature review found them to be safe and moderately efficacious because of reasonable good cross protection. Even a moderately efficacious vaccine like rotavirus vaccine could significantly improve the outcome if disease burden is high. Therefore, it is being included in National Immunization Programme of India.

    Differences in religious faith-based viewpoints (controversies) on the sanctity of human life, acceptable behaviour, health-care technologies and health-care services contribute to the widespread variations in health care worldwide. Faith-linked controversies include family planning, child protection (especially child marriage, female genital mutilation, and immunisation), stigma and harm reduction, violence against women, sexual and reproductive health and HIV, gender, end-of-life issues, and faith activities including prayer. Buddhism, Christianity, Hinduism, Islam, Judaism, and traditional beliefs have similarities and differences in their viewpoints. Improved understanding by health-care providers of the heterogeneity of viewpoints, both within and between faiths, and their effect on health care is important for clinical medicine, public-health programmes, and health-care policy. Increased appreciation in faith leaders of the effect of their teachings on health care is also crucial. This Series paper outlines some faith-related controversies, describes how they influence health-care provision and uptake, and identifies opportunities for research and increased interaction between faith leaders and health-care providers to improve health care.

    Full Text Available Reading as one of the four skills has always been as a part of the syllabus in English instruction. Based on the Pra survey, reading comprehension of the students of the first grade of SMA N 1 Rumbia is still low, most of them still lack structure knowledge and vocabulary, and their reading frequency in reading is still low. There are two techniques presented as a solution in this research. They are STAD Technique and Jigsaw technique. The objective of this research is to find out the difference result of using STAD and Jigsaw technique toward students’ reading comprehension in recount text at different high and low reading frequency and to find out there is significant interaction and comparison of reading comprehension in recount text, learning technique, and different reading frequency at the first grade students of SMA N 1 Rumbia academic year 2012/2013. The method of investigation is held through quantitative research. The researcher uses true experimental research. In this experiment, the the researcher applies factorials design.

    Many controversies and uncertainties surround resuscitation of hemorrhagic shock caused by vascular trauma. Whereas the basic pathophysiology is better understood, much remains to be learned about the many immunologic cascades that lead to problems beyond those of initial fluid resuscitation or operative hemostasis. Fluid therapy is on the verge of significant advances with substitute oxygen carriers, yet surgeons are still beset with questions of how much and what type of initial fluid to provide. Finally, the parameters chosen to guide therapy and the methods used to monitor patients present other interesting issues.

    This paper examines the lessons to be learnt from the organ retention controversy in the Republic of Ireland. The paper emphasises the importance of good communication between clinicians and families of deceased persons and a move away from a medical culture based on paternalism to a partnership approach between clinicians and patients based on mutual trust and understanding. A model of authorisation rather than consent is proposed as the way forward for dealing with the difficult and traumatic experience of asking families for permission to carry out a post mortem examination on their deceased child.

    2015-10-10

    Oral cavity carcinoma (OCC) remains a major cause of morbidity and mortality in patients with head and neck cancer. Although the incidence has decreased over the last decade, outcomes remain stagnant with only a 5% improvement in overall survival in the last 20 years. Although surgical resection remains the primary treatment modality, several areas of controversy exist with regard to work-up, management of the primary and neck tumors, and adjuvant therapy. As surgical techniques evolve, so has the delivery of radiotherapy and systemic treatment, which have helped to improve the outcomes for patients with advanced disease. Recently, the addition of cetuximab has shown promise as a way to improve outcomes while minimizing toxicity, and this remains an active area of study in the adjuvant setting. Advances in microvascular free-flap reconstruction have extended the limits of resection and enabled enhanced restoration of function and cosmesis. While these advances have led to limited survival benefit, evaluation of alternative modalities has gained interest on the basis of success in other head and neck subsites. Organ preservation with definitive chemoradiotherapy, though proven in the larynx and pharynx, remains controversial in OCC. Likewise, although the association of human papillomavirus is well established in oropharyngeal carcinoma, it has not been proven in the pathogenesis or survival of OCC. Future study of the molecular biology and pathogenesis of OCC should offer additional insight into screening, treatment selection, and novel therapeutic approaches. © 2015 by American Society of Clinical Oncology.

    2008-01-01

    The etiology and pathogenesis of certain types of disease remain controversial and stand like a bridge that crosses infectious, autoimmune and autoinflammatory pathways. Infection, for example, may initiate a disease, although it is the genetic regulation in the host, the interplay between virus or bacteria persistence and autoimmunity that produces the later phases of disease, the antigenic determinants responsible for inducing autoimmune disease, and the pathogenetic effector mechanisms. Infections agents cause pericarditis, but in 85% of cases it is "idiopathic". It has also been shown that persistent Clamydia pneumoniae, Porphyromonas gingivalis, and Helicobacter pylori infections cause host immunity and promote atherogenesis. A number of infectious agents have been suggested as potential triggers for primary biliary cirrhosis. Infections and vaccinations have also been linked to the pathogenesis of fibromyalgia syndrome, a common, chronic syndrome of widespread pain. Many factors are also responsible for fever of unknown origin such as: infections, autoimmunity disease, etc. However, it is difficult to determine a direct correlation between the infections agents in such a large group of diseases. The aim of this review is to analyze some of the controversies about the role of infections in autoimmune diseases.

  15. Controversial Issues in Thyroid Cancer Management.

    Science.gov (United States)

    Tuttle, R Michael

    2018-04-13

    The lack of prospective randomized clinical trials for most management topics in differentiated thyroid cancer force us to make management recommendations based on retrospective observational data which is often incomplete, subject to selection bias, and conflicting. Therefore, it is not surprising that many aspects of thyroid cancer management remain controversial and not well defined. This review will examine the controversies surrounding three important topics in thyroid cancer management: (1) the option of thyroid lobectomy as initial therapy for thyroid cancer, (2) the proper use of preoperative neck imaging to optimize the completeness of the initial surgical procedure, and (3) the selective use RAI therapy as remnant ablation, adjuvant treatment or treatment of known persistent/recurrent disease. As thyroid cancer management moves toward a much more risk adapted approach to personalized management recommendations, clinicians and patients must balance the risks and benefits of the potential management options to arrive at a management plan that is optimized based on both patient preferences/values and the philosophy/experience of the local disease management team.

    2010-01-01

    Evolutionary psychology has emerged over the past 15 years as a major theoretical perspective, generating an increasing volume of empirical studies and assuming a larger presence within psychological science. At the same time, it has generated critiques and remains controversial among some psychologists. Some of the controversy stems from hypotheses that go against traditional psychological theories; some from empirical findings that may have disturbing implications; some from misunderstandings about the logic of evolutionary psychology; and some from reasonable scientific concerns about its underlying framework. This article identifies some of the most common concerns and attempts to elucidate evolutionary psychology's stance pertaining to them. These include issues of testability and falsifiability; the domain specificity versus domain generality of psychological mechanisms; the role of novel environments as they interact with evolved psychological circuits; the role of genes in the conceptual structure of evolutionary psychology; the roles of learning, socialization, and culture in evolutionary psychology; and the practical value of applied evolutionary psychology. The article concludes with a discussion of the limitations of current evolutionary psychology. 2009 APA, all rights reserved.

    Lately, glaciers have been subjects of unceasing controversy. Current debate about planned hydroelectric facilities—a US7- to 10-billion megaproject—in a pristine glacierized area of Patagonia, Chile [Romero Toledo et al., 2009; Vince, 2010], has raised anew the matter of how glaciologists and global change experts can contribute their knowledge to civic debates on important issues. There has been greater respect for science in this controversy than in some previous debates over projects that pertain to glaciers, although valid economic motivations again could trump science and drive a solution to the energy supply problem before the associated safety and environmental problems are understood. The connection between glaciers and climate change—both anthropogenic and natural—is fundamental to glaciology and to glaciers' practical importance for water and hydropower resources, agriculture, tourism, mining, natural hazards, ecosystem conservation, and sea level [Buytaert et al., 2010; Glasser et al., 2011]. The conflict between conservation and development can be sharper in glacierized regions than almost anywhere else. Glaciers occur in spectacular natural landscapes, but they also supply prodigious exploitable meltwater.

    In Korea, the incidence of prostate cancer in 2002 was sixth among the malignancies diagnosed in men, but it was the most rapidly increasing cancer. As many prostate cancers are indistinguishable from normal prostate tissue as determined on an ultrasound examination, the randomized systematic transrectal ultrasound guided prostate biopsy is the gold standard for the detection of prostate cancer. Indications for a TRUS guided prostate biopsy including an elevated level of prostate specific antigen (PSA) and an abnormal digital rectal exam, as well as patient preparation and procedure techniques including anesthesia are reviewed in this report. This report also considers controversies about a prostate biopsy such as the ideal number of biopsy cores, usefulness of PSA derivatives, effective methods for local anesthesia, and the use of patient preparation questionnaires covering topics such as the paucity of anticoagulants and the use of antibiotics and enemas

    Drawing on the experience and academic research of the 1990s, this chapter identifies five lessons: • Openness to trade has been a central element of successful growth strategies. In all countries that have sustained growth the share of trade in gross domestic product (GDP) has increased, and trade barriers have been reduced. • Trade is an opportunity, not a guarantee.While trade reforms can help accelerate integration in the world economy and strengthen an effective ...

    Holden,N.E.

    2008-08-11

    Two and a quarter centuries ago, a heavy mineral ore was found which was thought to contain a new chemical element called heavy stone (or tungsten in Swedish). A few years later, the metal was separated from its oxide and the new element (Z=74) was called wolfram. Over the years since that time, both the names wolfram and tungsten were attached to this element in various countries. Sixty years ago, IUPAC chose wolfram as the official name for the element. A few years later, under pressure from the press in the USA, the alternative name tungsten was also allowed by IUPAC. Now the original, official name 'wolfram' has been deleted by IUPAC as one of the two alternate names for the element. The history of this controversy is described here.

  3. Diabetes mellitus and tuberculosis facts and controversies

    Science.gov (United States)

    2013-01-01

    Tuberculosis (TB) and diabetes mellitus (DM) are both important health issues. A bidirectional association between them has been demonstrated by many researchers. The link of DM and TB is more prominent in developing countries where TB is endemic and the burden of diabetes mellitus is increasing. The association between diabetes and tuberculosis may be the next challenge for global tuberculosis control worldwide. Proper planning and collaboration are necessary to reduce the dual burden of diabetes and TB. One model similar to the TB-HIV program for prevention, screening and treatment of both diseases can be the best approach. In this paper, we review existing data and discuss the matters of controversy that would be helpful for determining research priorities in different countries. PMID:24360398

  4. Some remarks about the 'controversial discussions'.

    Hayman, A

    1994-04-01

    In 1943-44, the British Psycho-Analytical Society held the 'Controversial Discussions' in an attempt to resolve various disagreements then current in the theory, practice and teaching of psychoanalysis. This paper selects and assesses in some detail some of the arguments that emerged around the concepts of 'unconscious phantasy' and 'unconscious conflict'. Inter alia, they included arguments about assumed early events, about ways of interpreting and assessing evidence, about modes and different levels of conceptualisation, about interpretations of Freud and about changes in psychoanalyic theory. Attempts to achieve mutual understanding existed side by side with total and sometimes rancorous disagreement. Attention is given to sometimes irresolvable communicative and conceptual difficulties that arose and still arise, from differences in meaning that different psychoanalytic thinkers assigned and still assign to each of the two conceptual terms, 'unconscious phantasy' and 'unconscious conflict'.

    To examine and analyse the controversy over psychiatric aspects of the case of Norwegian far right mass murderer Anders Behring Breivik. Because of a basic acceptance of methodological individualism and scientific positivism, mainstream psychiatry is currently ill suited to being broadly applied to the spheres of politics and political violence. Rather than jettison psychiatric insights in such cases, the choices facing the profession are either to accept the narrowness of its utility or to work towards a theoretical framework that sees the individual psyche as socially embedded rather than as socially constitutive, and psychiatric science itself as socially constructed and hence inescapably value-laden. © The Royal Australian and New Zealand College of Psychiatrists 2014.

    2016-01-01

    Acute kidney injury (AKI) is a significant independent risk factor for morbidity and mortality. In the last ten years a large number of publications have highlighted the limitations of traditional approaches and the inadequacies of conventional biomarkers to diagnose and monitor renal insufficiency in the acute setting. A great effort was directed not only to the discovery and validation of new biomarkers aimed to detect AKI more accurately but also to standardise the definition of AKI. Despite the advances in both areas, biomarkers have not yet entered into routine clinical practice and the definition of this syndrome has many areas of uncertainty. This review will discuss the controversies in diagnosis and the potential of novel biomarkers to improve the definition of the syndrome. PMID:28167845

    If the publication of twelve drawings of the Prophet Mohammad in the Danish newspaper Jyllands-Posten, which sparked the ‘cartoon controversy', was wrong, why might this be the case? The article considers four arguments advanced in relation to the quite similar Rushdie affair for judging...... such publications to be wrong, and asks whether they provide plausible moral reasons against such publications, and whether they justify legal restrictions on freedom of speech. The arguments concern: (a) the consistent extension of group defamation legislation to cover Muslims; (b) offence to religious...... for judging the kind of publications under consideration to be morally wrong or suitable objects for legal restrictions. The argument from oppression is different, however, in pointing to different kinds of factors, but its applicability is limited both by a number of conditions for when oppression provides...

    Moriarty, Camilla; Carroll, Will

    2016-12-01

    Ibuprofen, a propionic acid derivative, is a non-steroidal anti-inflammatory drug. The oral formulation is widely used in paediatric practice and after paracetamol it is one of the most common drugs prescribed for children in hospital. The treatment of fever with antipyretics such as ibuprofen is controversial as fever is the normal response of the body to infection and unless the child becomes distressed or symptomatic, fever alone should not be routinely treated. Combined treatment with paracetamol and ibuprofen is commonly undertaken but almost certainly is not helpful. This article aims to describe the indications and mode of action of the drug, outline its pharmacokinetics and highlight the important key messages regarding its use in clinical practice.

  10. The controversy on chronic cerebrospinal venous insufficiency

    2013-08-01

    Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

  12. Rasch techniques for detecting bias in performance assessments: an example comparing the performance of native and non-native speakers on a test of academic English.

    Elder, Catherine; McNamara, Tim; Congdon, Peter

    2003-01-01

    The use of common tasks and rating procedures when assessing the communicative skills of students from highly diverse linguistic and cultural backgrounds poses particular measurement challenges, which have thus far received little research attention. If assessment tasks or criteria are found to function differentially for particular subpopulations within a test candidature with the same or a similar level of criterion ability, then the test is open to charges of bias in favour of one or other group. While there have been numerous studies involving dichotomous language test items (see e.g. Chen and Henning, 1985 and more recently Elder, 1996) few studies have considered the issue of bias in relation to performance based tasks which are assessed subjectively, via analytic and holistic rating scales. The paper demonstrates how Rasch analytic procedures can be applied to the investigation of item bias or differential item functioning (DIF) in both dichotomous and scalar items on a test of English for academic purposes. The data were gathered from a pilot English language test administered to a representative sample of undergraduate students (N= 139) enrolled in their first year of study at an English-medium university. The sample included native speakers of English who had completed up to 12 years of secondary schooling in their first language (L1) and immigrant students, mainly from Asian language backgrounds, with varying degrees of prior English language instruction and exposure. The purpose of the test was to diagnose the academic English needs of incoming undergraduates so that additional support could be offered to those deemed at risk of failure in their university study. Some of the tasks included in the assessment procedure involved objectively-scored items (measuring vocabulary knowledge, text-editing skills and reading and listening comprehension) whereas others (i.e. a report and an argumentative writing task) were subjectively-scored. The study models a

    Nanotechnology is an exciting and powerful discipline of science; the altered properties of which have offered many new and profitable products and applications. Agriculture, food and medicine sector industries have been investing more in nanotechnology research. Plants or their extracts provide a biological synthesis route of several metallic nanoparticles which is more eco-friendly and allows a controlled synthesis with well-defined size and shape. The rapid drug delivery in the presence of a carrier is a recent development to treat patients with nanoparticles of certain metals. The engineered nanoparticles are more useful in increasing the crop production, although this issue is still in infancy. This is simply due to the unprecedented and unforeseen health hazard and environmental concern. The well-known metal ions such as zinc, iron and copper are essential constituents of several enzymes found in the human system even though the indiscriminate use of similar other metal nanoparticle in food and medicine without clinical trial is not advisable. This review is intended to describe the novel phytosynthesis of metal and metal oxide nanoparticles with regard to their shape, size, structure and diverse application in almost all fields of medicine, agriculture and technology. We have also emphasized the concept and controversial mechanism of green synthesis of nanoparticles.

Use of this coin appears as an alternative to traditional currencies, but they are not under the control of no body, are devoid of inflation and maintain the anonymity of users. Following the evolution of this new type of coin, we proposed in this paper to present some general aspects of this coin focusing on global controversies on using Bitcoin. We have reviewed several myths that have arisen with the development and penetration of its on market and because it is a volatile coin can generate huge gains but and huge losses, we have studied fluctuation and implications for users and investors and the attraction of the drug dealers and criminals for using virtual currency, Bitcoin. At the end of the paper, based on the analysis we have tried to outline the future of this modern payment system. Thus, we found that lately, in that its value has fluctuated strongly, and increased buyer confidence, but appeared and increased cyber attacks, and the fear that if the state has no a role in protecting citizens from fraud, we can assist at the development of financial schemes extremely dangerous. The financial experts believe that if the world banks would jointly solve all the problems, the virtual money will have a real chance of life.

  16. Biliary tract cancers: current concepts and controversies.

    Leonard, Gregory D; O'Reilly, Eileen M

    2005-02-01

    Biliary tract cancer, which consists of gall bladder cancer and cholangio-carcinoma, presents many challenges to practising physicians. It is a relatively rare cancer that often causes a diagnostic dilemma, as its presentation may be similar to that of non-malignant conditions. In many cases, histological or cytological confirmation of a cancer diagnosis is not possible preoperatively. The management of this disease is also complex due to a morbid patient population and limited data on the optimal therapeutic approach. Surgery remains the mainstay of treatment, although the extent of resection required is still debated. The role of adjuvant therapy is also controversial, but a combined modality approach appears to be beneficial in patients with a high risk of recurrence, such as those with node positive tumors or positive resection margins. When surgery is not possible, the prognosis of patients with biliary tract cancer is very poor. In unresectable patients, the combination of chemotherapy and radiotherapy can result in a prolonged survival for some patients. In the palliative setting, biliary stenting and other supportive measures can alleviate symptoms and improve survival. Gemcitabine-based combination chemotherapy may also provide successful palliation and has achieved response rates of approximately 30% and a median survival of > 15 months in one study. Ultimately, treatment decisions should be individualised and participation in clinical trials is encouraged. Further progress in the management of biliary tract cancer is anticipated using biological therapies and continued research is essential to discover the optimal treatment for this challenging disease.

  17. Energy controversy: the role of nuclear power

    1975-02-01

    The objective of the paper presented is to show that nuclear fission power is the best, and maybe the only, alternative source of energy. It is written for a wide range of readers, including non-scientists and scientists who are not particularly informed on the issues involved. The first question considered concerns man's need for energy; it is concluded that conservation measures alone cannot suffice. Next, the earth's energy sources are examined, and the extent of each is estimated in the simple context of the length of time it could last at present use rates. Only nuclear fission, nuclear fusion, and solar energy can provide for future time scales commensurate with man's historic past, while avoiding the possibility of catastrophic social upheaval. Fusion and solar energy are rejected on technological grounds because the world energy problem is so pressing that one cannot gamble on hopes for future technological breakthroughs. Thus, only nuclear fission meets the twin criteria of technological feasibility and adequate resource base. Each of the controversial issues surrounding nuclear fission energy is examined in some detail. The conclusion is reached that none is serious, and that nuclear fission offers by far the best energy source from environmental, economic, longevity, and overall safety standpoints

  18. Iron hypothesis of cardiovascular disease: still controversial.

    Science.gov (United States)

    Aursulesei, Viviana; Cozma, A; Krasniqi, A

    2014-01-01

    Iron hypothesis has been a controversial subject for over 30 years as many studies support its role as a risk factor for cardiovascular disease, while other studies found no evidence to support it. The conflicting results are accounted for by the non-homogeneity of trial design in terms of population inclusion criteria and different endpoints, non-uniform use of parameters for assessing iron role, and incomplete understanding of the mechanisms of action. The nature of iron is dual, being of crucial importance for the human body, but also toxic as "free iron" induces oxidative stress. Under physiological conditions, there are efficient and complex mechanisms against iron-induced oxidative stress, which could be reproduced for creating new, intelligent antioxidants. Iron depletion improves the cardiovascular prognosis only if serum concentration is at the lowest limit of normal ranges. However, low iron levels and the type of dietary iron intake correlate with atherosclerotic cardiovascular disease, influence the ischemic endpoints in the elderly, and exert negative impact on heart failure prognosis. So far, the causal relation and involved mechanisms are not fully elucidated. Iron overload is a difficult and frequent condition, involving the cardiovascular system by specific pathogenic pathways, therefore determining a particular form of restrictive cardiomyopathy and vaso-occlusive arterial damage.

    2001-05-01

    Gregor Mendel was a 19(th) century priest and botanist who developed the fundamental laws of inheritance. The year 2000 marked a century since the rediscovery of those laws and the beginning of genetics. Although Mendel is now recognized as the founder of genetics, significant controversy ensued about his work throughout the 20(th) century. In this paper, we review five of the most contentious issues by looking at the historical record through the lens of current botanical science: (1) Are Mendel's data too good to be true? (2) Is Mendel's description of his experiments fictitious? (3) Did Mendel articulate the laws of inheritance attributed to him? (4) Did Mendel detect but not mention linkage? (5) Did Mendel support or oppose Darwin?A synthesis of botanical and historical evidence supports our conclusions: Mendel did not fabricate his data, his description of his experiments is literal, he articulated the laws of inheritance attributed to him insofar as was possible given the information he had, he did not detect linkage, and he neither strongly supported nor opposed Darwin.

    Full Text Available Maxillary reconstruction is still an evolving art when compared to the reconstruction of the mandible. The defects of maxilla apart from affecting the functions of the speech, swallowing and mastication also cause cosmetic disfigurement. Rehabilitation of the form and function in patients with maxillary defects is either by using an obturator prosthesis or by a surgical reconstruction. Literature is abundant with a variety of reconstructive methods. The classification systems are also varied, with no universal acceptance of any one of them. The oncologic safety of these procedures is still debated, and conclusive evidence in this regard has not emerged yet. Management of the orbit is also not yet addressed properly. Tissue engineering, that has been hyped to be one of the possible solutions for this vexing reconstructive problem, has not come out with reliable and reproducible results so far. This review article discusses the rationale and oncological safety of the reconstructing the maxillary defects, critically analyzes the classification systems, offers the different reconstructive methods and touches upon the controversies in this subject. The management of the retained and exenterated orbit associated with maxillectomy is reviewed. The surgical morbidity, complications and the recent advances in this field are also looked into. An algorithm, based on our experience, is presented.

  1. The nuclear energy controversy in Austria

    Oszuszky, F.; Szeless, A.

    1981-01-01

    The sociological aspects of the energy issue have become of overwhelming importance in the last few years. As a result, traditional considerations such as the importance of adequate and cheap energy supplies as the basis for growth, and the necessity, in a time of politically uncertain oil supplies, of energy supply security and diversity, have been equalled in importance, and sometimes replaced, by arguments about the social goals to be achieved. Nuclear energy has been selected as the vehicle for a socio-political debate on the controversial issue of the application of large-scale technology. Beyond that it has acquired a symbolic role in what is really an emotional attack on the political systems, economy and culture of present day civilization. It stands for the concentration of power, the centralization of technology and society, and man's dependence on the products of that centralization. Nuclear power is seen as one of the motors of further economic growth and thus an apparent pioneer of the further destruction of our natural and social environment. (author)

  2. Cognitive styles: Controversial issues and research problems

    Natalia N. Volkova

    2016-06-01

    Full Text Available The paper presents an analytical review of cognitive styles research, considering the problems of its theory, methodology, measurement and practical applications. Issues concerning the prospects, as well as theoretical and practical relevance of cognitive styles research, are discussed. We examine the main causes leading to researchers’ declining interest to study of cognitive styles, related to theory, methodology, measurement and practical applications. The main problems discussed relate to lack of clear definition and common theoretical framework. Moreover, the number of empirical studies prevails over the one aimed at theoretical generalization of empirical results and findings, and therefore the primacy of empirics appears. We analyze the possible ways of advancing the field, suggested research programs and potential perspectives for future research. We pose questions of the relationship between cognitive styles and other psychological constructs, such as abilities and cognitive strategies. We emphasize the need to develop integrative models of cognitive styles in order to systematize and organize a large number of existing cognitive styles dimensions. The main controversial issues concerning cognitive styles’ stability and value are considered. We suggest that cognitive style is a psychological mean of cognitive tasks solving, based on both situation circumstances and subject’s current cognitive resources. Issues concerning cognitive styles may answer the question on the nature of individual differences and clarify psychological mechanisms of personality-situation interaction. Furthermore, it may serve as a basis for integrated studies at the areas of personality and cognitive psychology.

  4. Cellulite: advances in treatment: facts and controversies.

    Science.gov (United States)

    Emanuele, Enzo

    2013-01-01

    Cellulite is traditionally considered a highly prevalent aesthetic condition in women. From a clinical standpoint, it is characterized by a cottage-cheese-like appearance of the skin, which can be most commonly found in certain areas of the body (eg, thighs, buttocks, and legs). Although cellulite is generally asymptomatic, the more severe stages can be accompanied by the appearance of painful nodules and increased local temperature, which are suggestive of an inflammatory reaction occurring in the dermis and in the underlying subcutaneous adipose tissue. Whether cellulite is a real disease or only a disturbing aesthetic issue is still a matter of controversy. This debate notwithstanding, it seems clear from market trends that there is considerable commercial interest in developing effective strategies aimed at reducing the cottage-cheese-like appearance of cellulite areas. Quite disturbingly, the majority of treatment attempts to date have been conducted in an empirical manner and without the application of rigorous scientific methodology. This is likely due--at least in part--to the lack of major, evidence-based pathophysiological insights into the nature of this condition. More stringent regulatory control is needed over commercial products aiming at improving the appearance of cellulite. © 2013 Elsevier Inc. All rights reserved.

  5. The Controversy over the Buddhas of Bamiyan

    Full Text Available The author analyses a rare case of mirror-outrage that followed the destruction of the Buddhas of Bamiyan. This event brought the Taliban and the international community into opposition in 2001. The article first stresses the intriguing paradigmatic similarities between the destruction of the Buddhas and the destruction of Artemis Temple in 356 BC, when the eradication of a monument, sacred as well as emblematic of a cultural heritage, was perceived as an outrage against piety and beauty. This analogy helps the author emphasize the uncertainty regarding the identification of the victims: were they ‘the people’ in general, abstract deities, or specific communities? The article then elaborates on the argumentation and self-justification presented by the Taliban, and underlies their sense of indignation at a protest coming from ‘Christian’ countries, which they saw as exclusively concerned with saving ‘idols’ but ignorant of the ordeal endured by the Afghans. It finally argues that conflicting visions over the very meaning of ‘cultural heritage’ were at the core of the controversy.

    Full Text Available The Republic of Serbia is one of the last countries that legally regulate the private security sector, which is a new conceptual system of the national security system. Since the law is expected to solve many issues and dilemmas, and bring order to the area, which by some accounts is a very profitable branch of economy. Expectations were that by the end to regulate issues such as: 1 the need for institutionalization of partnership between the public and private sectors for mutual benefit, 2 the need of expressing mutual interest to establish the desired condition of security in the entire society and 3 the need to define the mechanisms and authority to achieve mentioned above. Based on this, legal framework of private security should explicitly provide: 1 a new role of the private sector, 2 communication and data exchange between the public and private sector, 3 mandatory notification about prepared or committed criminal acts on which there is information, 4 cooperation in the tasks of necessarily protected facilities, 4 cooperation in crisis situations including natural disasters, traffic accidents, strikes, sabotage, terrorist attacks, etc., 5 cooperate in the selection and training of staff and 6 cooperation in planning activities and project design of security. This paper presents a critical review of some theoretical and professional controversies in the solutions provided by law, for the purpose of answering whether it is achieving the purpose of passing of such a legal act.

    Full Text Available Academic Marketing is an investment in a future dominated by The Forth Industrial Revolution and Globalization and not an expense. This aspect will basically alter our way to teach and to learn. In its dimensions, arguably changes will be like anything we has seen before. We try to assess how will be all unfold but, anyway, academic field response at this challenge should be integrated and comprehensive, involving all stakeholders both public and private sectors, because these changes herald upheaval of whole organizations. The educational service is a special one, delivered today but with effects in the future, the future of the individual, the future of generation, the future of nations. The educational service policy adapted to the requirements of time, brings to the front the opportunity of academic marketing. To analyze demand in a professional way, to measure trends and correlated university programs with the forecast demand for jobs, it is the subject. In the case of academic education, we are talking also about cost, distribution and promotion policies, but being a special service we also discuss about ethic boundaries. This work is an open chapter focusing studies on academic megamarketing, the work keeping up with the pace of change, students enrolment mobility, overtakes job market, and an imposed win-win-win formula, applied for students, local community and academic field.

  8. Cold dark matter: Controversies on small scales.

    Weinberg, David H; Bullock, James S; Governato, Fabio; Kuzio de Naray, Rachel; Peter, Annika H G

    2015-10-06

    The cold dark matter (CDM) cosmological model has been remarkably successful in explaining cosmic structure over an enormous span of redshift, but it has faced persistent challenges from observations that probe the innermost regions of dark matter halos and the properties of the Milky Way's dwarf galaxy satellites. We review the current observational and theoretical status of these "small-scale controversies." Cosmological simulations that incorporate only gravity and collisionless CDM predict halos with abundant substructure and central densities that are too high to match constraints from galaxy dynamics. The solution could lie in baryonic physics: Recent numerical simulations and analytical models suggest that gravitational potential fluctuations tied to efficient supernova feedback can flatten the central cusps of halos in massive galaxies, and a combination of feedback and low star formation efficiency could explain why most of the dark matter subhalos orbiting the Milky Way do not host visible galaxies. However, it is not clear that this solution can work in the lowest mass galaxies, where discrepancies are observed. Alternatively, the small-scale conflicts could be evidence of more complex physics in the dark sector itself. For example, elastic scattering from strong dark matter self-interactions can alter predicted halo mass profiles, leading to good agreement with observations across a wide range of galaxy mass. Gravitational lensing and dynamical perturbations of tidal streams in the stellar halo provide evidence for an abundant population of low-mass subhalos in accord with CDM predictions. These observational approaches will get more powerful over the next few years.

  9. Addressing the nuclear controversy on university campuses

    A strong anti-nuclear sentiment exists on many university campuses. Young minds are eager to adopt causes which purport to reflect new intellectual approaches to social, political and economic issues. Hence, the opposition to nuclear power can be made to seem to be based on: (1) technical study of nuclear plants; (2) concern for the environment; (3) concern for public health and safety; (4) requirements for an improved economic order; and (5) demand for public decision on technical issues. All these elements could attract student and faculty interest and support. To contend with this problem in the USA, Westinghouse Electric Corporation attempted to achieve a dialogue with the student and faculty audiences. The development and results of the programme up to mid-1977 are reported in this paper. A small group of young nuclear engineers was chosen to undergo comprehensive training on the controversy and contemporary campus issues in the States to be visited. Selection and training emphasized the ability of the engineers to relate to the students as their peers. They were encouraged to speak candidly and for themselves. Thus, they did not give the impression of being merely typical corporate spokesmen. The rapport made possible by this approach is very important to the success of such an effort. Invitations to debate before student audiences were issued to leading opposition groups and to the news media. Response by the media has been outstandingly favourable: not only has the coverage been extensive, but it has carried the pro-nuclear arguments to large audiences on a scale and with a credibility not otherwise achievable. The results up to May 1977, in eight States, have been extremely encouraging. Other countries are invited to learn more about the ''Campus America'' programme in order to evaluate whether or not such an approach, with appropriate modification, could prove effective in their own situations.

  10. The Gaia Controversy: AGU'S Chapman Conference

    Science.gov (United States)

    Kauffman, Eric G.

    The controversial Gaia Hypothesis of James Lovelock of Coombe Mill, Launceston, Cornwall, U.K., and his colleagues variously contends that throughout Earth history the global biosphere has influenced, even controlled, the physicochemical evolution of Earth's environments (especially oceans and climate) for its own benefit. Since the origin of life, the biosphere has influenced selective pressures on evolution, maintained the Earth in a kind of homeostasis, and thus created an environmental optimum through time, regulated by and for the biosphere. Rarely has a hypothesis immediately sparked such passionate response. There is something in it for everybody, from hard core scientists to philosophers, ultraconservationists, students of world religions, mystics, politicians, and space enthusiasts; they were all there in San Diego, March 7-11, 1988, for the AGU Chapman Conference on Gaia Hypotheses. For 4 days an impressive list of specialists presented and debated the pros and cons of Gaia Hypotheses from diverse perspectives: modern and ancient biology, ecology, biochemistry, the physicochemical systems of the Earth, oceans, and atmosphere, and the evolution of the solar system. Focus was on modern to Pleistocene atmosphere-ocean-Earth systems, case histories of their interaction with the biosphere, and relatively simple models drawn from these observations and projected back through time. Equivalent studies on the geological and paleobiological history of the Earth-life system over the past 3.5 b.y. were underrepresented. Extended debates that followed generally strong presentations were lively, argumentative, and remarkably civil despite widely held views. The grace with which Jim Lovelock moved between his strongest critics and supporters set high standards for the debates. Everybody acknowledged a high learning curve.

  11. Lichen Planus Pigmentosus: The Controversial Consensus

    Ghosh, Aparajita; Coondoo, Arijit

    2016-01-01

    A pigmented variant of lichen planus (LP) was first reported from India in 1974 by Bhutani et al. who coined the term LP pigmentosus (LPP) to give a descriptive nomenclature to it. LP has a number of variants, one of which is LPP. This disease has also later been reported from the Middle East, Latin America, Korea, and Japan, especially in people with darker skin. It has an insidious onset. Initially, small, black or brown macules appear on sun-exposed areas. They later merge to form large hyperpigmented patches. The disease principally affects the sun-exposed areas of the body such as the face, trunk, and upper extremities. The oral mucosa may rarely be involved. However, the palms, soles, and nails are not affected. Histologically, the epidermis is atrophic along with vacuolar degeneration of basal cell layer. The dermis exhibits incontinence of pigment with scattered melanophages and a sparse follicular or perivascular infiltrate. There is a considerable similarity in histopathological findings between LPP and erythema dyschromicum perstans. However, there are immunologic and clinical differences between the two. These observations have led to a controversy regarding the identity of the two entities. While some dermatologists consider them to be the same, others have opined that the two should be considered as distinctly different diseases. A number of associations such as hepatitis C virus infection, frontal fibrosing alopecia, acrokeratosis of Bazex and nephrotic syndrome have been reported with LPP. A rare variant, LPP inversus, with similar clinical and histopathological findings was reported in 2001. As opposed to LPP, this variant occurs in covered intertriginous locations such as groins and axillae and mostly affects white-skinned persons. PMID:27688435

    Full Text Available Critical thinking enjoys almost universal support, except when applied to controversial topics. Yet it is these topics that are often the most effective initiators of critical thinking exercises that improve students’ rational approaches to challenging problems. The use of controversial issues to promote critical thinking requires an institutional commitment to academic freedom in order to survive. In some institutional contexts, the most crucial need for critical thinking is the very condition under which it is least likely to be applied. Instead, avoidance of controversy seems to be the predominant policy of institutions fearful of expensive lawsuits or damaging public relations. Several trends are decreasing the likelihood that critical thinking is applied in the classroom to challenging topics: demands for increased accountability from legislatures; scrutiny of adopted content standards; oversight of Internet and other intellectual work of professors affiliated with the universities; student challenges to faculty instruction; and attempts to curtail ideological diversity. This paper describes these current dynamics which erode academic freedom and thus the ability to apply critical thinking to controversial topics. The paper also recommends that institutions and faculty adopt clearly delineated policies related to academic freedom in order to ensure faculty freedom to promote critical thinking. Awareness of how these trends impact the instructional climate enables teachers to design instruction and be more proactive in guaranteeing that critical thinking about controversial topics is able to flourish under academic freedom.

    2014-04-01

    Despite the controversy regarding clinical efficacy, dental hygienists use the diode laser as an adjunct to non-surgical periodontal therapy. The technique to maximize successful laser therapy outcome is controversial as well. The purpose of this review is to explore the scientific foundation of the controversy surrounding the use of the diode laser as an adjunct to non-surgical periodontal therapy. Further, this paper addresses the weaknesses in study design, the heterogeneity of methodology in the published clinical studies, especially the laser parameters, and how these issues impact the collective clinical and microbial data, and thus conclusions regarding clinical efficacy. Evaluation of the literature identifies possible mechanisms that could contribute to the varied, often conflicting results among laser studies that are the foundation of the controversy surrounding clinical efficacy. These mechanisms include current paradigms of periodontal biofilm behavior, tissue response to laser therapy being dependent on tissue type and health, and that the successful therapeutic treatment window is specific to the target tissue, biofilm composition, laser wavelength, and laser energy delivered. Lastly, this paper discusses laser parameters used in the various clinical studies, and how their diversity contributes to the controversy. Although this review does not establish clinical efficacy, it does reveal the scientific foundation of the controversy and the need for standardized, well designed randomized controlled clinical trials to develop specific guidelines for using the laser as an adjunct to non-surgical periodontal therapy. Using evidence-based laser guidelines would allow dental hygienists to provide more effective non-surgical periodontal care.

  1. Why Map Issues? On Controversy Analysis as a Digital Method.

    Science.gov (United States)

    Marres, Noortje

    2015-09-01

    This article takes stock of recent efforts to implement controversy analysis as a digital method in the study of science, technology, and society (STS) and beyond and outlines a distinctive approach to address the problem of digital bias. Digital media technologies exert significant influence on the enactment of controversy in online settings, and this risks undermining the substantive focus of controversy analysis conducted by digital means. To address this problem, I propose a shift in thematic focus from controversy analysis to issue mapping. The article begins by distinguishing between three broad frameworks that currently guide the development of controversy analysis as a digital method, namely, demarcationist, discursive, and empiricist. Each has been adopted in STS, but only the last one offers a digital "move beyond impartiality." I demonstrate this approach by analyzing issues of Internet governance with the aid of the social media platform Twitter.

    2014-05-01

    Academic freedom can be defined as immunity against adverse reactions from the general public, designed to keep scholars unintimidated and productive even after they have published controversial ideas. Francesca Minerva claims that this notion of strict instrumental academic freedom is supported by Ronald Dworkin, and that anonymity would effectively defend the sphere of immunity implied by it. Against this, I argue that the idea defended by Minerva finds no support in the work by Dworkin referred to; that anonymity would not in most cases effectively protect the kind of immunity sought after; and that in some cases it would not even be desirable to protect scholars from public reactions to their controversial claims. © 2014 John Wiley & Sons Ltd.

    Este artículo sugiere que esta época es la mejor y peor para la labor académica. La mejor en cuanto hay más publicaciones académicas que nunca. Y la peor porque sobra mucho de estas publicaciones. Trabajando en las condiciones competitivas del capitalismo académico, los académicos se sienten en la necesidad de continuar publicando, independientemente de que tengan algo que decir. Las presiones de publicar continuamente y promover la propia perspectiva se reflejan en la manera en la que los científicos sociales están escribiendo. Y es que los académicos utilizan un lenguaje técnico basado en sustantivos, con una precisión menor a la del lenguaje ordinario. Los estudiantes de postgrado han sido educados en esta manera de escribir como una condición previa a iniciarse en las ciencias sociales. Así, la naturaleza misma del capitalismo académico no sólo determina las condiciones en las que los académicos trabajan, sino que también afecta su manera de escribir.


    This paper suggests that it is the best and worst of times for academic work. It is the best of times because there are more academics publishing than ever before. It is the worst of times because there is much unnecessary publication. Working in the competitive conditions of academic capitalism, academics feel impelled to keep publishing, whether or not they have anything to say. The pressures to publish continually and to promote one’s own approach are reflected in the way that social scientists are writing. Academics use a noun-based technical language, which is less precise than ordinary language. Postgraduates are taught this way of writing as a precondition for entering the social sciences. In this way, the nature of academic capitalism not only determines the conditions under which academics are working but it affects the way that they are writing.

  7. Is alveolar cleft reconstruction still controversial? (Review of literature

    Directory of Open Access Journals (Sweden)

    Sameh A. Seifeldin

    2016-01-01

    Full Text Available Cleft lip and palate (CL/P is a frequent congenital malformation that manifests in several varieties including unilateral or bilateral and complete or incomplete. Alveolar cleft reconstruction remains controversial with regard to timing, graft materials, surgical techniques, and methods of evaluation. Many studies have been conducted addressing these points to develop an acceptable universal protocol for managing CL/P. The primary goal of alveolar cleft reconstruction in CL/P patients is to provide a bony bridge at the cleft site that allows maxillary arch continuity, oronasal fistula repair, eruption of the permanent dentition into the newly formed bone, enhances nasal symmetry through providing alar base support, orthodontic movement and placement of osseointegrated implants when indicated. Other goals include improving speech, improvement of periodontal conditions, establishing better oral hygiene, and limiting growth disturbances. In order to rehabilitate oral function in CL/P patients alveolar bone grafting is necessary. Secondary bone grafting is the most widely accepted method for treating alveolar clefts. Autogenous bone graft is the primary source for reconstructing alveolar cleft defects and is currently the preferred grafting material.

    Significant progress in the field of VaD resulted from publication of the NINIDS-AIREN Diagnostic Criteria for VaD (G.C. Roman, T.K. Tatemichi, T. Erkinjuntti, et al., Vascular dementia (VaD): diagnostic criteria for research studies. Report of the NINDS-AIREN International Workshop. Neurology 43 (1993) 250-260). Epidemiological studies confirmed the importance of VaD as the second most common cause of dementia in the elderly, representing 15-20% of all cases of dementia. In Europe and North America, Alzheimer's disease (AD) predominates over VaD in a 2:1 ratio; in contrast, in Japan and China VaD accounts for almost 50% of all dementias. Case-control studies have identified risk factors for VaD including ageing, hypertension, diabetes mellitus, hyperlipidemia, recurrent stroke, cardiac disease, smoking, sleep apnea, and more recently, hyperhomocysteinemia, among others. Hypertension treatment may prevent VaD and AD. This finding has enormous importance from the Public Health viewpoint to decrease the future number of patients with dementia in the elderly. Along with advances in the field of VaD came a number of controversies and damaging misconceptions and myths. Myth no. 1--Vascular dementia is a non-entity: The false idea that VaD does not exist is particularly destructive because it creates the perspective that VaD is unworthy of study or research. A condition that either does not exist or represents only a minute proportion of all cases of dementia in the elderly, lacks public health relevance and becomes a low priority for research by funding agencies and industry. In fact, vascular brain lesions are the commonest and most important component of dementia in the elderly. Myth no. 2--Vascular dementia is so difficult to diagnose that only experts can recognize and identify it accurately: VaD does exist and the diagnosis of post-stroke VaD, in particular is straightforward. Most cases fulfill NINDS-AIREN criteria for probable VaD; i.e., (1) there is acute onset

  9. Academic underachievement: A neurodevelopmental perspective

    Directory of Open Access Journals (Sweden)

    K. Shapiro Bruce, MD

    2011-03-01

    Full Text Available Academic underachievement is a common presenting symptom and has many different causes. The disorders that describe academic underachievement are based on the child’s function in cognitive, academic, or behavioral domains. The disorders that are associated with academic underachievement are final common pathways that have different etiologies and mechanisms. Multiple disorders are the rule because brain dysfunction in childhood usually affects multiple functions. Consequently, management programs must be individualized, comprehensive and address issues related to the child, school, and family. Treatment plans include parent training, academic accommodations, techniques to maintain self-esteem, and psychopharmacologic approaches. Ongoing monitoring of the management programs is necessary to detect important comorbidities that may emerge, to modify the program to meet the changing academic and social demands that occur as the child ages, and to provide current information. The outcome for children with academic underachievement is most dependent on the underlying disorder. Health providers have multiple roles to play in the prevention, detection, diagnosis and management of children with academic underachievement.

In short, the book fails to deliver on its promise. But I also argue that the wave of attention Faye's book has attracted since its English translation appeared is symptomatic of a broad set of problems plaguing contemporary Anglophone philosophy. © 2011 Wiley Periodicals, Inc.

    Full Text Available This communication is the summary of Internet discussions held by members of the Indian Association of Pediatric Surgeons (IAPS in June 2005. It reflects the opinion and practice of Indian pediatric surgeons on the treatment of childhood empyema thoracis (ET. Despite the availability of broad-spectrum antibiotics, a large number of ET in advanced stages is still seen in India. The management of ET appears to depend on the stage of pathology, the status of underlying lung and proper usage of antibiotic adjuncts. Intercostal tube drainage of pleural space is sufficient for stage 1 empyema. Thoracoscopic decortication reduces the treatment cost and morbidity of stage 2 disease. However, stage 3 lesions with very thick pleural peels require open decortication. Pros and cons of these three modalities of treatment are discussed. The members also describe the various innovative techniques, that they found useful in the surgical management of ET.

  18. The Chilling Effect: How Do Researchers React to Controversy?

    Kempner, Joanna

    2008-01-01

    Background Can political controversy have a “chilling effect” on the production of new science? This is a timely concern, given how often American politicians are accused of undermining science for political purposes. Yet little is known about how scientists react to these kinds of controversies. Methods and Findings Drawing on interview (n = 30) and survey data (n = 82), this study examines the reactions of scientists whose National Institutes of Health (NIH)-funded grants were implicated in a highly publicized political controversy. Critics charged that these grants were “a waste of taxpayer money.” The NIH defended each grant and no funding was rescinded. Nevertheless, this study finds that many of the scientists whose grants were criticized now engage in self-censorship. About half of the sample said that they now remove potentially controversial words from their grant and a quarter reported eliminating entire topics from their research agendas. Four researchers reportedly chose to move into more secure positions entirely, either outside academia or in jobs that guaranteed salaries. About 10% of the group reported that this controversy strengthened their commitment to complete their research and disseminate it widely. Conclusions These findings provide evidence that political controversies can shape what scientists choose to study. Debates about the politics of science usually focus on the direct suppression, distortion, and manipulation of scientific results. This study suggests that scholars must also examine how scientists may self-censor in response to political events. PMID:19018657

  19. Mapping Controversies with Social Media: The Case for Symmetry

    Directory of Open Access Journals (Sweden)

    Noortje Marres

    2015-09-01

    Full Text Available This article assesses the usefulness for social media research of controversy analysis, an approach developed in Science and Technology Studies (STS and related fields. We propose that this approach can help to address an important methodological problem in social media research, namely, the tension between social media as resource for social research and as an empirical object in its own right. Initially developed for analyzing interactions between science, technology, and society, controversy analysis has in recent decades been implemented digitally to study public debates and issues dynamics online. A key feature of controversy analysis as a digital method, we argue, is that it enables a symmetrical approach to the study of media-technological dynamics and issue dynamics. It allows us to pay equal attention to the ways in which a digital platform like Twitter mediates public issues, and to how controversies mediate “social media” as an object of public attention. To sketch the contours of such a symmetrical approach, the article discusses examples from a recent social media research project in which we mapped issues of “privacy” and “surveillance” in the wake of the National Security Agency (NSA data leak by Edward Snowden in June 2013. Through a discussion of social media research practice, we then outline a symmetrical approach to analyzing controversy with social media. We conclude that the digital implementation of such an approach requires further exchanges between social media researchers and controversy analysts.

  20. Resistance training during preadolescence. Issues and controversies.

    Science.gov (United States)

    Blimkie, C J

    1993-06-01

    High intensity resistance training appears to be effective in increasing strength in preadolescents. Children make similar relative (percentage improvement), but smaller absolute, strength gains compared with adolescents and young adults in response to similar resistance training programmes. Resistance training appears to have little if any effect on muscle size, and strength gains during training have been associated with increases in levels of neuromuscular activation and changes in intrinsic contractile characteristics of muscle. Although unsubstantiated, improved motor coordination probably also contributes to the increase in strength, especially for more complex strength manoeuvres. On the basis of limited information, training-induced strength gains are lost during detraining, and the decay in strength has been associated with a reduction in neuromuscular activation. Short term resistance training appears to have no effect on somatic growth (height or weight) and body composition, and no proven positive influence on sports performance, injury rate or recovery from injury during preadolescence. Weightlifting has proved injurious to some children, especially when unsupervised and without instruction in proper weightlifting technique and load selection. In contrast, the risk of injury from prudently prescribed and closely supervised resistance training appears to be low during preadolescence. Lastly, short term resistance training appears to have no detrimental effect during preadolescence on either cardiorespiratory fitness or resting blood pressure.

    2016-02-01

    In 2010-2012, the controversy over fracking grew rapidly, first in the United States, and then internationally. An important step was the anti-fracking documentary film Gasland. With help from celebrity sources, the film was produced and won a prize at the Sundance Film Festival by early 2010 and had an Oscar nomination by early 2011, in the meantime popularizing potent images of hazard including tainted aquifers and ignitable water running from kitchen faucets. During this period, major US news organizations paid little attention to the issue. The offshore Deepwater Horizon disaster of April 2010 spurred The New York Times to prolific reporting on potential risks of the new onshore technique for extracting shale gas. With flagship news coverage, the controversy had by 2012 gained wide media attention that evoked public concern and opposition, spreading from the United States to other nations. © The Author(s) 2014.

  9. Studying a Controversy amongst Pashtuns of Torghar, Balochistan, Pakistan

    Directory of Open Access Journals (Sweden)

    Luc Bellon

    2007-10-01

    Full Text Available Much has been written about the political structures of tribal groups. The present article looks at political dynamics amongst Pashtuns of Balochistan, through the prism of a controversy. The sociological interest of studying the arguments used during a controversy has been underlined by Boltanski and Thevenot. A controversy finishes by the establishment, through consensus, of a common agreement upon accepted norms, determined limits, redefinition of social values, etc. The advantage of focusing on the argumentation itself is to avoid taking the agreement as a pre-established social truth, a reference that concerned people would reluctantly challenge. To study a controversy is to study the social realities in the making, to study the archaeology of collective consensus, to reinstate history, contingencies and individual plurality within the social dynamics and to take seriously their performative actions alongside other social determinisms. This article shows that to study controversy is a way not only to set light on political dynamics and structures, but also to discuss the impact and definition of concepts such as segmentarity, equality, rights, interests, and their relevance within the Pashtun society which was observed.

  10. Current concepts and controversies in the diagnosis and treatment of attention deficit hyperactivity disorder.

    Jensen, P S

    2000-04-01

    Concerns about possible over-diagnosis and over-treatment of attention deficit hyperactivity disorder (ADHD) have been prominent in media reports, as have various competing claims about the safety and efficacy of the various treatments for ADHD. Drawing upon the results of the recent National Institutes of Health Consensus Conference, this paper reviews the evidence concerning these controversial areas. Although there do appear to be pockets of over-prescribing in selected communities, the best available evidence suggests that across the United States substantial underdiagnosis continues to occur, and only 50% of all children with ADHD are being treated with stimulant medications. Among those who are treated with stimulant medications, inadequate treatment is quite common. Substantial evidence suggests that for ADHD symptoms, stimulants are more effective than behavioral therapies in head-to-head comparisons. Combined medication and behavioral treatments do not offer any meaningful advantages over medication treatments alone for ADHD symptoms. For other areas of functioning, however (social skills, academic performance, etc.), combined treatments appear to offer some modest advantages over single treatment approaches. Although research findings show that ADHD can indeed be rigorously and reliably diagnosed under optimal conditions, and that carefully delivered treatments can yield substantial benefits, such best practices do not appear to be taking place in the real world. Thus, although the above controversies are facing some resolution in principal, in practice much remains to be done.

    CERN Document Server

    Jensen, Carsten

    2000-01-01

    In 1920s, a long-lasting controversy on the interpretation of nuclear beta spectrum arose between Lise Meitner and Charles Drummond Ellis. This controversy, and the reactions from the contending parties when it was settled, reflect clearly the difference between the scientific communities in Berlin and Cambridge at that time. The Meitner-Ellis controversy ended in 1929, and it left an anomaly that attracted leading theoretical physicists. A new dispute, this time between Niels Bohr and Wolfgang Pauli, broke out. It concerned the explanation of the continuity of the primary beta particles and dominated the discussions for the next five years. Pauli argued for a new particle, and Bohr for a new theory; both suggestions were radical steps, but they reflected two different ways of doing physics.

  14. Review of the recent carbon dioxide-climate controversy

    International Nuclear Information System (INIS)

    Luther, F.M.; Cess, R.D.

    1992-01-01

    Model calculations of the climatic impact of the increasing atmospheric carbon dioxide (CO 2 ) concentration consistently suggest that a doubling of the CO 2 concentration would lead to a warming of global average surface air temperatures by as much as several degrees Celsius. In this appendix, this controversy about the effect of CO 2 on climate is reviewed. Because the surface energy balance approach to estimating climate sensitivity has been the source of much of the controversy, a review of this approach is presented. It is shown that prior applications of this approach violate the law of conservation of energy (the first law of thermodynamics); therefore, these results are incorrect. Empirical data indicating the relationship between atmospheric emittance and surface vapor pressure and surface air temperature are shown to be consistent with climate model calculations. Consequently, it is not the experimental data that are the basis of the controversy, but rather the analysis and interpretation of these data

  15. Empowerment in healthcare policy making: three domains of substantive controversy.

    Chiapperino, Luca; Tengland, Per-Anders

    2015-12-01

    This paper distinguishes between the uses of empowerment across different contexts in healthcare policy and health promotion, providing a model for the ethical and political scrutiny of those uses. We argue that the controversies currently engendered by empowerment are better understood by means of a historical distinction between two concepts of empowerment, namely, what we call the radical empowerment approach and the new wave of empowerment. Building on this distinction, we present a research agenda for ethicists and policy makers, highlighting three domains of controversy raised by the new wave of empowerment, namely: (1) the relationship between empowerment and paternalistic interferences on the part of professionals; (2) the evaluative commitment of empowerment strategies to the achievement of health-related goals; and (3) the problems arising from the emphasis on responsibility for health in recent uses of empowerment. Finally, we encourage the explicit theorisation of these moral controversies as a necessary step for the development and implementation of ethically legitimate empowerment processes.

  17. Humanitarian law: the controversial historical construction of a universal moral

    Directory of Open Access Journals (Sweden)

    Soraya Nour Sckell

    2012-01-01

    Full Text Available Humanitarian law was conceived by legal and moral normativism founded on universal principles. Despite its undeniable universal moral content, its formulations and application methods are however the result of historical conflicts. This article aims to analyze how the universality of humanitarian law is produced by highly controversial conflicts. It is necessary to overcome the antagonism between an analysis that focuses on the moral undeniable value of humanitarian law by ignoring its controversies and an analysis that focuses on social antagonism questioning the achievability of the moral and universal value of humanitarian law. For this, we must consider that humanitarian law is a construction. It appears as autonomous and independent of power relationships, as based on the rationality of morality and thus worthy of universal recognition. Yet its development is only possible when one considers the historical roots of reason. It is only through political struggle that humanitarian law is realized in history. The aim of this paper is to analyze how the universal nature of humanitarian law is produced by highly controversial conflicts. Firstly, an analysis is offered on the universal but at the same controversial character in the codification of humanitarian law, recalling controversies around the creation of the Additional Protocols of 1977 (Section 1. Next, an analysis is given on the conflictual character of organizations supporting humanitarian law, taking in account conflicts between the Red Cross and Doctors Without Borders and controversies around the ambitions to pass from an humanitarian law to a right of humanitarian intervention (Section 2. Finally, a reflection is offered on how the theories of international relations that most appropriately grasp the universal nature of humanitarian law must be complemented by a "historical sociology of the universal" that embraces the conflicting historical dimension in the construction of the

    controversial issues compared to teacher candidates who come from in rural areas. In addition, results of the study indicate that level of participation in classroom discussions regarding controversial issues increased as they become sophomores and seniors. It is also important to say that culture of the universities might influence students’ response to controversial discussions. The researcher of the study found that level of participation varies based on academic culture of the universities. For example, in the universities that are considered as conservative teacher candidates participated in the discussions less than their counterparts who are enrolled in universities that are known as democratic. Therefore, these factors ougth to be carefully considered before they are educated about how to employ controversial issues as an instructional tool. The pre-service teachers suggested that they would like to be respected, the teachers should be objective during discussions, and they should not try to impose their ideas to the students.

    Full Text Available Assuming the importance of science education, from early years, aiming to educate citizens capable of thinking critically and act in scientific and technological contexts, a study was carried out in order to develop learning situations focused on controversial socio-scientific issues to promote students’ argumentation skills and scientific knowledge building / mobilization. The study was based on a qualitative methodology, following an action research plan. It was conducted with a class of 3th grade, having been addressed controversial socio-scientific issues, framed in science curriculum topics, using strategies of debate, role-play and argumentative essays. Data was collected using an analyzing instrument of student´s oral and written productions. In data analysis the privileged technique was content analysis. The results suggest that students mobilized requested scientific knowledge, showing improvement in the effective use of argumentation skills required. This allows us to conclude that the approach of controversial socio-scientific issues contributes to the promotion students´ argumentation skills as well as for scientific knowledge construction / mobilization.

    infection and IBD have been contentious. While some investigators have claimed to find persistent measles infection among patients with IBD, others, using highly sensitive polymerase chain reaction techniques, have not been able to replicate the findings. Recent controversy has centred on whether there is any evidence for molecular mimicry in the pathogenesis of IBD. In summary, available evidence does not support an association between measles-containing vaccines and risk of IBD, nor between measles infection and IBD. While further research is necessary into the causal factors underlying Crohn's disease and ulcerative colitis, continued public education efforts are needed to reassure the public about vaccine safety and to prevent declines in vaccine coverage.

    This article analyses, from a bioethics journal editor's perspective, the threats to academic freedom and freedom of expression that academic bioethicists and academic bioethics journals are subjected to by political activists applying pressure from outside of the academy. I defend bioethicists' academic freedom to reach and defend conclusions many find offensive and 'wrong'. However, I also support the view that academics arguing controversial matters such as, for instance, the moral legitimacy of infanticide should take clear responsibility for the views they defend and should not try to hide behind analytical philosophers' rationales such as wanting to test an argument for the sake of testing an argument. This article proposes that bioethics journals establish higher-quality requirements and more stringent mechanisms of peer review than usual for iconoclastic articles.

    There are a number of sources available to prescribers to stay up to date about medicines. Prescribers in rural areas in developing countries however, may not able to access some of them. Interventions to improve prescribing can be educational, managerial, and regulatory or use a mix of strategies. Detailing by the pharmaceutical industry is widespread. Academic detailing (AD) has been classically seen as a form of continuing medical education in which a trained health professional such as a physician or pharmacist visits physicians in their offices to provide evidence-based information. Face-to-face sessions, preferably on an individual basis, clear educational and behavioural objectives, establishing credibility with respect to objectivity, stimulating physician interaction, use of concise graphic educational materials, highlighting key messages, and when possible, providing positive reinforcement of improved practices in follow-up visits can increase success of AD initiatives. AD is common in developed countries and certain examples have been cited in this review. In developing countries the authors have come across reports of AD in Pakistan, Sudan, Argentina and Uruguay, Bihar state in India, Zambia, Cuba, Indonesia and Mexico. AD had a consistent, small but potentially significant impact on prescribing practices. AD has much less resources at its command compared to the efforts by the industry. Steps have to be taken to formally start AD in Nepal and there may be specific hindering factors similar to those in other developing nations.

    Sousa, Anete Araújo de; Azevedo, Elaine de; Lima, Elinete Eliete de; Silva, Ana Paula Ferreira da

    2012-06-01

    The study of controversies is a methodological tool that generates knowledge about the social and political dimensions of science. This approach can be used to understand and explore the topic of organic foods. The present study aimed to analyze the controversies regarding the status of organic foods. We carried out a review of studies published since 1990 in three websites: International Foundation for Organic Agriculture, Soil Association, and Food and Agriculture Organization. The following controversies were identified: 1) effects on human health of the presence of chemical contaminants in organic foods; 2) the quality of organic foods as compared to conventionally grown foods; and 3) price of organic foods. Based on this review, it is possible to conclude that, even though organic foods stand out for their low toxicity, higher durability, and nutritional content of some items, more comparative studies are required to confirm the nutritional superiority of organic foods and to solve the controversies. The discussion must be contextualized within a broad spectrum of health promotion, in which organic farming appears associated with the support for small farming, biodiversity, and local sustainable development, so as to increase offer and demand for organic products at fair prices for individual and institutional consumers.

    2008-02-01

    Full Text Available Abstract The number of children in the US taking prescription drugs for emotional and behavioral disturbances is growing dramatically. This growth in the use of psychotropic drugs in pediatric populations has given rise to multiple controversies, ranging from concerns over off-label use and long-term safety to debates about the societal value and cultural meaning of pharmacological treatment of childhood behavioral and emotional disorders. This commentary summarizes the authors' eight main findings from the first of five workshops that seek to understand and produce descriptions of these controversies. The workshop series is convened by The Hastings Center, a bioethics research institute located in Garrison, New York, U.S.A.

  16. Using deliberation to address controversial issues: Developing Holocaust education curriculum.

    Directory of Open Access Journals (Sweden)

    THOMAS MISCO

    2007-10-01

    Full Text Available This paper explores how a cross-cultural project responded to the need for new Holocaust educational materials for the Republic of Latvia through the method of curriculum deliberation. Analysis of interview, observational, and document data drawn from seven curriculum writers and numerous project members suggest that curriculum deliberation helped awaken a controversial and silenced history while attending to a wide range of needs and concerns for a variety of stakeholders. The findings highlight structural features that empowered the curriculum writers as they engaged in protracted rumination, reflected upon competing norms, and considered the nuances of the curriculum problem in relation to implementation. Understanding the process, challenges, and promises of cross-cultural curriculum deliberation holds significance for educators, curricularists, and educational researchers wishing to advance teaching and learning within silenced histories and controversial issues.

  17. Nuclear energy: public controversies and the analysis of risks

    International Nuclear Information System (INIS)

    Sills, D.L.

    1984-01-01

    Energy is a social concept, the product of social, economic, and political processes that define certain raw materials as resources and thus convert them into usable energy. Like all social concepts, energy is controversial. Out of a wide range of controversies, three are selected for analysis here: (1) the relationship of nuclear power systems to nuclear weapons proliferation; (2) the risks of terrorism and sabotage associated with the operation of nuclear power facilities, including threats to civil liberties; and (3) the problems associated with the long-term management of radioactive wastes. The final section of the paper describes various modes of analyzing risks and the perception of risks. It is concluded that it may take many decades to learn whether nuclear energy is as natural a source of electrical power as wells are of drinking water, or whether nuclear energy is a horror that mankind in the 1980s or 1990s took a hard look at and then backed away.

    2007-09-01

    Various topics in otology cause controversy among otologists internationally. The resulting variety of diagnostic and surgical concepts reflects differences between surgical schools and the lack of structured studies in the field. During the "Third Instructional Workshop of the European Academy of Otology and Neuro-Otology," we interviewed 100 invited instructors using a written questionnaire on 13 controversial topics in otology. The analyses of the survey showed a variety of different approaches in most otologic topics. A further exchange of experiences and discussions in expert panels such as the Instructional Workshop of the European Academy of Otology and Neuro-Otology may help standardize concepts in otology for a safe, efficient, and cost-effective standard of care in otology.

  19. Distinguishing heat from light in debate over controversial fossils.

    Science.gov (United States)

    Donoghue, Philip C J; Purnell, Mark A

    2009-02-01

    Fossil organisms offer our only direct insight into how the distinctive body plans of extant organisms were assembled. However, realizing the potential evolutionary significance of fossils can be hampered by controversy over their interpretation. Here, as a guide to evaluating palaeontological debates, we outline the process and pitfalls of fossil interpretation. The physical remains of controversial fossils should be reconstructed before interpreting homologies, and choice of interpretative model should be explicit and justified. Extinct taxa lack characters diagnostic of extant clades because the characters had not yet evolved, because of secondary loss, or because they have rotted away. The latter, if not taken into account, will lead to the spurious assignment of fossils to basally branching clades. Conflicting interpretations of fossils can often be resolved by considering all the steps in the process of anatomical analysis and phylogenetic placement, although we must accept that some fossil organisms are simply too incompletely preserved for their evolutionary significance to be realized.

  20. The pertussis vaccine controversy in Great Britain, 1974-1986.

    Science.gov (United States)

    Baker, Jeffrey P

    2003-09-08

    This historical essay analyzes the role played by Great Britain in the pertussis vaccine controversy of the 1970s and 1980s. Public backlash against this vaccine not only took place earlier in Britain than the United States, but also was so widespread that a series of whooping cough epidemics soon followed. As with the more recent dispute involving measles-mumps-rubella (MMR) vaccine and autism, the United Kingdom played a primary role in defining, promoting, and ultimately exporting this controversy. This essay seeks to explain this phenomenon by situating it in Britain's long history of suspicion regarding vaccines evident among both the public and the medical profession, a theme dating back to the compulsory vaccination laws of the 19th century. It argues that anti-vaccinationism, far from being simply a new development related to the public's lack of awareness of childhood vaccine-preventable illness, actually represents a revival of a much older movement.

    Baker, Jeffrey P

    2008-02-01

    The controversy regarding the once widely used mercury-containing preservative thimerosal in childhood vaccines has raised many historical questions that have not been adequately explored. Why was this preservative incorporated in the first place? Was there any real evidence that it caused harm? And how did thimerosal become linked in the public mind to the "autism epidemic"? I examine the origins of the thimerosal controversy and their legacy for the debate that has followed. More specifically, I explore the parallel histories of three factors that converged to create the crisis: vaccine preservatives, mercury poisoning, and autism. An understanding of this history provides important lessons for physicians and policymakers seeking to preserve the public's trust in the nation's vaccine system.

    The book deals with the psychological aspects of the nuclear controversy. An attempt is made to describe, in psychological terms, arrange, explain and, in this sense, 'comprehend' the phenomenon of the nuclear controversy in the light of the following facts: - individual and archetypal spectra of associations arising in the minds of many people in combination with the term 'nuclear power plant', the existence of different psychological types; the suggestion and psychological regression in the group. Especially the nuclear opponents, more or less successfully, have used the individual and archetypal association spectrum as an instrument to further their own ends and have thus contributed to the erection of psychological barriers against nuclear power in the minds of many people.

    The development and utilization of nuclear energy has led to conflicts of larger dimensions in our society. What has been the role of the mass communication media in this discussion. Did they fulfill their duty to inform the public, did they actively foster discussions about the facts to be considered, and did they play their part in public opinion making by publishing critical analyses. These are questions answered by this book by presenting analyses of newspaper articles on the nuclear controversy, facts and figures on the opinions and information published in the daily newspapers on the subject of nuclear energy utilization, and analyses of tendencies pro or contra nuclear energy as expressed by the various articles. By an evaluation of the history of discussions, the development and modifications of the arguments put forward and the reactions shown by the various social groups involved in the process are illustrated and commented in the light of the controversy becoming more acute.

  10. Controversies in the Surgical Management of Spinal Cord Injuries

    Directory of Open Access Journals (Sweden)

    Ahmed M. Raslan

    2012-01-01

    Full Text Available Traumatic spinal cord injury (SCI affects over 200,000 people in the USA and is a major source of morbidity, mortality, and societal cost. Management of SCI includes several components. Acute management includes medical agents and surgical treatment that usually includes either all or a combination of reduction, decompression, and stabilization. Physical therapy and rehabilitation and late onset SCI problems also play a role. A review of the literature in regard to surgical management of SCI patients in the acute setting was undertaken. The controversy surrounding whether reduction is safe, or not, and whether prereduction magnetic resonance (MR imaging to rule out traumatic disc herniation is essential is discussed. The controversial role of timing of surgical intervention and the choice of surgical approach in acute, incomplete, and acute traumatic SCI patients are reviewed. Surgical treatment is an essential tool in management of SCI patients and the controversy surrounding the timing of surgery remains unresolved. Presurgical reduction is considered safe and essential in the management of SCI with loss of alignment, at least as an initial step in the overall care of a SCI patient. Future prospective collection of outcome data that would suffice as evidence-based is recommended and necessary.

  11. The controversy over the minimum quantum requirement for oxygen evolution.

    Science.gov (United States)

    Hill, Jane F; Govindjee

    2014-10-01

    During the early- to mid-twentieth century, a bitter controversy raged among researchers on photosynthesis regarding the minimum number of light quanta required for the evolution of one molecule of oxygen. From 1923 until his death in 1970, Otto Warburg insisted that this value was about three or four quanta. Beginning in the late 1930s, Robert Emerson and others on the opposing side consistently obtained a value of 8-12 quanta. Warburg changed the protocols of his experiments, sometimes in unexplained ways, yet he almost always arrived at a value of four or less, except eight in carbonate/bicarbonate buffer, which he dismissed as "unphysiological". This paper is largely an abbreviated form of the detailed story on the minimum quantum requirement of photosynthesis, as told by Nickelsen and Govindjee (The maximum quantum yield controversy: Otto Warburg and the "Midwest-Gang", 2011); we provide here a scientific thread, leaving out the voluminous private correspondence among the principal players that Nickelsen and Govindjee (2011) examined in conjunction with their analysis of the principals' published papers. We explore the development and course of the controversy and the ultimate resolution in favor of Emerson's result as the phenomenon of the two-light-reaction, two-pigment-system scheme of photosynthesis came to be understood. In addition, we include a brief discussion of the discovery by Otto Warburg of the requirement for bicarbonate in the Hill reaction.

  12. Reflections on academic video

    Directory of Open Access Journals (Sweden)

    Thommy Eriksson

    2012-11-01

    Full Text Available As academics we study, research and teach audiovisual media, yet rarely disseminate and mediate through it. Today, developments in production technologies have enabled academic researchers to create videos and mediate audiovisually. In academia it is taken for granted that everyone can write a text. Is it now time to assume that everyone can make a video essay? Using the online journal of academic videos Audiovisual Thinking and the videos published in it as a case study, this article seeks to reflect on the emergence and legacy of academic audiovisual dissemination. Anchoring academic video and audiovisual dissemination of knowledge in two critical traditions, documentary theory and semiotics, we will argue that academic video is in fact already present in a variety of academic disciplines, and that academic audiovisual essays are bringing trends and developments that have long been part of academic discourse to their logical conclusion.

  13. Brokered dialogue: A new research method for controversial health and social issues.

    Science.gov (United States)

    Parsons, Janet A; Lavery, James V

    2012-07-02

    Dialogue is a foundational feature of social life and an important way in which we come to understand one another. In situations of controversy dialogue is often absent because of a range of social barriers. We have developed a new film-based qualitative research method for studying controversial issues in healthcare and social policy. We call this method Brokered Dialogue. Theoretically informed by the traditions in narrative inquiry and visual anthropology, the method is premised on the idea that dialogue possesses features making it unique as a generator of new knowledge and opportunities for social intervention. Film is not only an extraordinarily rich data source, but an excellent medium for knowledge transfer and dissemination. The paper introduces the Brokered Dialogue method. We outline its critical steps, including the procedures for sampling, data collection and data analysis of both textual and visual data. Participants in a Brokered Dialogue engage in filmed interviews that capture their perspectives on a given topic; they then share their perspectives with, and pose questions of, one another through the medium of film. Using a participatory editing process, only footage that participants feel comfortable showing to others is incorporated. This technique offers participants a 'safe' space for respectful interaction. The editing process itself is analytic, and the final assembly of footage approximates a dialogue on the topic at hand. A link to a film produced from a project piloting the method is provided to demonstrate its real world application. Brokered Dialogue is a method for promoting respectful interactions among those with seemingly divergent views on a controversial topic and for discovering critical points of divergence that may represent pathways for improvement. While the end product is a 'film', the goal is to have these films used as catalysts for ongoing respectful dialogue and problem-solving concerning the topic at hand informing

    BACKGROUND: Tongue base cancer is one of the most lethal head and neck cancers. There is considerable controversy in the management of this disease with wide variation of opinion within the literature. METHODS: We discuss the presentation, diagnostic and therapeutic strategies which exist in the literature. Articles were reviewed from 1970 to 2007 within the Medline, Pubmed and Cochrane libraries. CONCLUSIONS: Smokers with a history of persistent unilateral neck pain, even in the absence of clinical signs warrant MRI neck imaging. Tongue base cancer organ preservation therapeutic strategies, radiation and concomitant platinum based chemotherapy, currently optimise oncologic and quality of life outcomes.

    Full Text Available Infective endocarditis is a life-threatening disease caused by a focus of infection within the heart. For clinicians and scientists, it has been a moving target that has an evolving microbiology and a changing patient demographic. In the absence of an extensive evidence base to guide clinical practice, controversies abound. Here, we review three main areas of uncertainty: first, in prevention of infective endocarditis, including the role of antibiotic prophylaxis and strategies to reduce health care-associated bacteraemia; second, in diagnosis, specifically the use of multimodality imaging; third, we discuss the optimal timing of surgical intervention and the challenges posed by increasing rates of cardiac device infection.

    Full Text Available Repair of inguinal hernia is one of the commonest operations performed by surgeons around the world. The treatment of this common problem has seen an evolution from the pure tissue repairs to the prosthetic repairs and in the recent past to laparoscopic repair. The fact that so many hernia repairs are practiced is a testimony to the fact that probably none is distinctly superior to the other. This review assesses the current status of surgery for repair of inguinal hernia and examines the various controversial issues surrounding the subject.

Many contemporary journalists have distrustfully considered Pamfil Șeicaru‟s Journal. This “horrendous” journalist was charged by his peers of having sustained this publication with funding provided by the Government. The controversies derived from this subject can be found in the articles and memories of those who knew the director of “Curentul”, but also in the novels which had him as a source of inspiration.

  2. When ideology and controversy collide: the case of Soviet science.

    Graham, L R

    1982-04-01

    Using specific examples such as the recombinant DNA debate, the author compares Soviet and American decision-making procedures in resolving bioethical controversies. In the Soviet Union, the dominant approach is for specialists to arrive at the "correct" position inherent in the world view of Marxism-Leninism. In the United States, it is common to negotiate a compromise between what science can achieve and what defenders of old values are willing to accept. The author concludes that, in both countries, resolution of biomedical issues is influenced more by culture and tradition than by logic and reason.

    Mammographic screening is effective in reducing mortality from breast cancer. The issue is not whether mammography is effective, but whether the false positive rate and false negative rates can be reduced. This review will discuss controversies including the reduction in breast cancer mortality, overdiagnosis, the ideal screening candidate, and the optimal imaging modality for breast cancer screening. The article will compare and contrast screening mammography, tomosynthesis, whole-breast screening ultrasound, magnetic resonance imaging, and molecular breast imaging. Though supplemental imaging modalities are being utilized to improve breast cancer diagnosis, mammography still remains the gold standard for breast cancer screening. Copyright © 2015 Elsevier Inc.

    Dessinioti, Clio; Katsambas, Andreas

    2013-01-01

    Seborrheic dermatitis (SD) is a common skin condition seen frequently in clinical practice. The use of varying terms such as sebopsoriasis, seborrheic dermatitis, seborrheic eczema, dandruff, and pityriasis capitis reflects the complex nature of this condition. Despite its frequency, much controversy remains regarding the pathogenesis of SD. This controversy extends to its classification in the spectrum of cutaneous diseases, having being classified as a form of dermatitis, a fungal disease, or an inflammatory disease, closely related with psoriasis. Some have postulated that SD is caused by Malassezia yeasts, based on the observation of their presence in affected skin and the therapeutic response to antifungal agents. Others have proposed that Malassezia is incidental to a primary inflammatory dermatosis that resulted in increased cell turnover, scaling, and inflammation in the epidermis, similar to psoriasis. The presence of host susceptibility factors, permitting the transition of M furfur to its pathogenic form, may be associated with immune response and inflammation. Metabolites produced by Malassezia species, including oleic acid, malssezin, and indole-3-carbaldehyde, have been implicated. SD also has been traditionally considered to be a form of dermatitis based on the presence of Malassezia in healthy skin, the absence the pathogenic mycelial form of Malassezia yeasts in SD, and its chronic course. As a result, proposed treatments vary, ranging from topical corticosteroids to topical antifungals and antimicrobial peptides. Copyright © 2013 Elsevier Inc. All rights reserved.

    2013-01-01

    The implication of the yeast genus Malassezia in skin diseases has been characterized by controversy, since the first description of the fungal nature of pityriasis versicolor in 1846 by Eichstedt. This is underscored by the existence of Malassezia yeasts as commensal but also by their implication in diseases with distinct absence of inflammation despite the heavy fungal load (pityriasis versicolor) or with characteristic inflammation (eg, seborrheic dermatitis, atopic dermatitis, folliculitis, or psoriasis). The description of 14 Malassezia species and subsequent worldwide epidemiologic studies did not reveal pathogenic species but rather disease-associated subtypes within species. Emerging evidence demonstrates that the interaction of Malassezia yeasts with the skin is multifaceted and entails constituents of the fungal wall (melanin, lipid cover), enzymes (lipases, phospholipases), and metabolic products (indoles), as well as the cellular components of the epidermis (keratinocytes, dendritic cells, and melanocytes). Understanding the complexity of their interactions will highlight the controversies on the clinical presentation of Malassezia-associated diseases and unravel the complexity of skin homeostatic mechanisms.

    Lacroix, Robert; O'Shaughnessy, Roy; McNiel, Dale E; Binder, Renée L

    2017-03-01

    In Canada, individuals found not criminally responsible on account of mental disorder are subject to the disposition recommendations of the Provincial or Territorial Review Board of the jurisdiction where the offense was committed. Bill C-14, known as "The Not Criminally Responsible Reform Act" made changes to the postverdict disposition process of these individuals. This legislation was consistent with a broader "tough-on-crime" agenda of the previous federal government. The legislative changes codify that Review Boards take public safety as the "paramount consideration" in making their recommendations. The legislation also creates a new "high-risk" category for certain offenders and imposes limitations on their liberty. Further, Bill C-14 seeks to enhance victim involvement in the disposition process. The passage of this legislation has generated significant controversy in the medical and legal fields. Critics have stated that there is an absence of empirical evidence on which to base the amendments, that the legislation was an overreaction to high-profile cases, and that Bill C-14 is in questionable compliance with the Canadian Charter of Rights and Freedoms. In this review, we explore the potential catalysts involved in the creation of Bill C-14, the controversy surrounding the legislation, and the potential future impact on practicing forensic psychiatrists and on the forensic mental health system in Canada. © 2017 American Academy of Psychiatry and the Law.

    Full Text Available The controversy surrounding the “ground zero mosque” is part of a larger debate about the place of Islam in U.S. public space. The controversy also reveals the ways in which the boundaries of American identity continue to be debated, often through struggles over who counts as a “real” American. It further demonstrates the extent to which Islam is figured as un-American and militant, and also the extent to which all Muslims are required to account for the actions of those who commit violence under the rubric of Islam. This paper will discuss how, due to the events of September 11, 2001, Muslims have engaged in a process of indigenizing American Islam. It will argue that the Park51 Islamic Community Center (or Ground Zero mosque is a reflection of this indigenization process. It will go on to argue that projects such as the Ground Zero mosque which try to establish Islam as an important part of the American religious landscape and insist on the freedom of worship as stated in the U.S. constitution, illustrate the ideological battlefield over the place of Islam in the U.S. The paper will also examine the possible ramifications of building the Park51 Islamic Community Center including how this will shape the role that Islam plays in the socio-political lives America Muslims.

    Based on a content analysis of 2047 journal articles of the years 1974 to 1977 on conflicts over nuclear power plants (Wyhl, Brokdorf), the book intends to analyze the role of the media in present social conflicts. The book presents facts and figures concerning the information and opinions on nuclear power in five newspapers and the bias of these newspapers in favour of nuclear power or against it. According to the author, newspaper journalists have failed at least in one thing: to explain the dimensions of the conflict with regard to social policy and to give background information on their own opinions. On the other hand, the press has proved its independence: It is not an extended arm of industrial PR departments - at least not in the nuclear controversy. The greater part of the articles is in opposition to nuclear power. The development and modifications of the arguments stated by the various groups active in the nuclear controversy are analyzed in dependence of the increasingly aggressive nature of the conflict.

    Full Text Available Vascular remodeling is an essential component of gestation. Endothelial progenitor cells (EPCs play an important role in the regulation of vascular homeostasis. The results of studies measuring the number of EPCs in normal pregnancies and in preeclampsia have been highly controversial or even contradictory because of some variations in technical issues and different methodologies enumerating three distinct subsets of EPCs: circulating angiogenic cells (CAC, colony forming unit endothelial cells (CFU-ECs, and endothelial colony-forming cells (ECFCs. In general, most studies have shown an increase in the number of CACs in the maternal circulation with a progression in the gestational age in normal pregnancies, while functional capacities measured by CFU-ECs and ECFCs remain intact. In the case of preeclampsia, mobilization of CACs and ECFCs occurs in the peripheral blood of pregnant women, but the functional capacities shown by culture of the derived colony-forming assays (CFU-EC and ECFC assays are altered. Furthermore, the number of all EPC subsets will be reduced in umbilical cord blood in the case of preeclampsia. As EPCs play an important role in the homeostasis of vascular networks, the difference in their frequency and functionality in normal pregnancies and those with preeclampsia can be expected. In this review, there was an attempt to provide a justification for these controversies.

    Full Text Available Pelvic organ prolapse and stress urinary incontinence are common conditions for which approximately 11% of women will undergo surgical intervention in their lifetime. The use of vaginal mesh for pelvic organ prolapse and stress urinary incontinence rose rapidly in the early 2000s as over 100 mesh products were introduced into the clinical armamentarium with little regulatory oversight for their use. US Food and Drug Administration Public Health Notifications in 2008 and 2011, as well as reclassification of transvaginal mesh for prolapse to class III in early 2016, were a response to debilitating complications associated with transvaginal mesh placement in many women. The midurethral sling has not been subject to the same reclassification and continues to be endorsed as the “gold standard” for surgical management of stress urinary incontinence by subspecialty societies. However, litigators have not differentiated between mesh for prolapse and mesh for incontinence. As such, all mesh, including that placed for stress urinary incontinence, faces continued controversy amidst an uncertain future. In this article, we review the background of the mesh controversy, recent developments, and the anticipated role of mesh in surgery for prolapse and stress urinary incontinence going forward.

    We investigated the level of patient knowledge and preferences over the currently controversial issues in TKA. One hundred patients who had decided to undergo TKA for advanced osteoarthritis were asked to complete a questionnaire inquiring their knowledge and preferences over three controversial issues: (1) computer assisted surgery (CAS), (2) minimal invasive surgery (MIS), and (3) ceramic femoral component. The patient preferences over the three issues were questioned again after they had been informed of advantages and disadvantages of each option using an explanatory document. Most (more than 75%) of the patients did not have sufficient knowledge and their knowledge was based on non-professional sources (more than 85%). Before the information was given, most (more than 80%) of the patients preferred a new option. After the information was provided, more patients preferred a standard option in the issues of CAS (60%) and MIS (88%). This study prompts health care providers to become more active in providing accurate information and to consider patients perspective in making decisions which will influence the benefits and risk of the patients.

  14. The rocky flats controversy on radionuclide soil action levels

    2004-01-01

    An account of the Rocky Flats radionuclide soil action level controversy is presented as: a case study for the purpose of understanding the nature and value of stakeholder involvement in the management of radiological hazards. The report consists of three main sections. The first section outlines the Rocky Flats story, including the Cold War era, which was characterised by secrecy and distrust, the post-Cold War era, in which trust and co-operation between risk managers and the public began to develop. This contrast between these two historical periods provides the context necessary to understand the radionuclide soil action level controversy, the main events of which are described in the second section. In the final section, the Rocky Flats case is briefly discussed within the framework of a general model of stakeholder involvement and the lessons learned from the case are identified: (1) without a basis in shared values, collaborative public involvement in the management of radiological hazards is not possible; (2) given a basis in shared values, collaborative public involvement can lead to improved solutions to the management of radiological hazards; and (3) risk managers should therefore seek to understand the values of public stakeholders and to identify ways, through stakeholder involvement, that those values can be incorporated in management practice.

    Sagar, P M; Pemberton, J H

    1995-01-01

    : The surgical management of ulcerative colitis has been revolutionized in recent years by the development of the ileal pouch-anal procedure. Although it is now the operation of choice for most patients, there remain several controversies. A variety of designs of ileal pouch are available each with advantages and disadvantages. The technique used to anastomose the pouch to the anal canal is also open to debate with some surgeons favoring distal mucosectomy with eradication of all disease and others choosing to perform a stapled anastomosis to achieve better functional results. The main concern for gastroenterologists, however, is the risk of development of pouchitis. The etiology, diagnosis, and treatment of this condition will also be discussed in this review as well as the more classical options for the surgical treatment of ulcerative colitis.

    State actions requiring adolescent girls to receive the human papillomavirus (HPV) vaccine created controversy following the vaccine's approval in 2006. Some health professionals worried that the controversy might dampen public support for those state policies and for other school immunizations in general. We fielded an experimental Internet survey to determine how controversy affects attitudes about vaccines. We discovered that public support for the HPV vaccine mandates wanes when the public is informed that the policies are controversial. However, the experimental survey also revealed that exposure to this policy controversy did not spill over and reduce public support for immunizations in general.

    Bucheb, Jose Alberto [PETROBRAS, Rio de Janeiro, RJ (Brazil)

    2008-07-01

    One of the main consequences of the growing number of the tendered blocks is the increasing probability of the discovery of oil and gas accumulations that extends through more than one concession. In these cases, the Brazilian Petroleum Law determines that the concessionaires of the adjoining blocks shall agree on the unitization of the production. In this context, the negotiations of the first agreements have brought some controversies not yet resolved. The first one is related to the instrument that will define the basis of the unitization process in case of non-agreement within the maximum period established by the ANP. Another issue still in discussion relates to the scope of the unitization process: field, block, vertical prism of indeterminate depth, vertical prism of determinate depth or reservoir (accumulation). Additionally, the unitization involving concessions with different local content commitments is analyzed. (author)

  2. Present state of the controversy about the grain boundary relaxation

    International Nuclear Information System (INIS)

    Povolo, F.; Molinas, B.J.

    1990-04-01

    An analysis of the internal friction produced by grain boundary relaxation in metals, alloys and ceramics is presented. The different interpretations given in the literature to relaxation phenomena occurring at temperatures above about half the melting point which include the influence of grain boundaries and their interaction with solutes and precipitates are discussed in detail. A complete set of the experimental data disposable in this field since 1972 until today is reviewed. Finally, some recent experiments are discussed and new ones are suggested. They might solve the actual controversy about the real origin of the relaxation phenomena observed. If this is the case, a considerable amount of information already published can be taken into account with a good degree of confidence. This information contributes to the description of the structure and behaviour of grain boundaries, both being important topics for materials science. (author). 119 refs, 21 figs, 1 tab

  3. Open access and the humanities contexts, controversies and the future

    Eve, Martin Paul

    2014-01-01

    If you work in a university, you are almost certain to have heard the term 'open access' in the past couple of years. You may also have heard either that it is the utopian answer to all the problems of research dissemination or perhaps that it marks the beginning of an apocalyptic new era of 'pay-to-say' publishing. In this book, Martin Paul Eve sets out the histories, contexts and controversies for open access, specifically in the humanities. Broaching practical elements alongside economic histories, open licensing, monographs and funder policies, this book is a must-read for both those new to ideas about open-access scholarly communications and those with an already keen interest in the latest developments for the humanities.

    2000-01-01

    The quest for understanding the past often contains a subjective component. Legends, myths, traditions and personal beliefs can unconsciously influence the interpretation of the scientific outcomes or, in the worst instances, even lead to forgery. Fortunately, an increasing number of scientific tools are available nowadays and can be combined to discredit such detriments and offer more reliable foundations for an objective analysis. Radiocarbon dating by AMS is a relatively non-invasive method and is particularly useful when valuable historical artefacts are involved. In this paper, we will present controversial cases where AMS is playing an important role in understanding the past. In particular, we will discuss the use of AMS to authenticate historical documents revealing a new version of the conquest of Peru by Pizarro in the early 1530s.

  5. Ecotheology and the theology of eating: controversies and convergencies

    Panu Pihkala

    2015-01-01

    Full Text Available Environmental theology (or, ecotheology developed slowly during the first half of the twentieth century and has become a major field of study since the late 1960s. While many of the issues discussed in ecotheological works have included consequences for food production and eating habits, these themes were often not explicitly discussed. The reasons for this are interesting and complex. Issues related to food have been culturally very sensitive and have manifold connections to religiosity. In regard to the discussion about the rights and value of animals, controversies have been seen to arise between ecotheology and ‘animal theology’. Recently, a new interest has arisen in the themes of food, eating, and Christian theology, which has resulted in a new field of literature which could be called the ‘theology of eating’. This article gives an overview of the relations between these fields, with an emphasis on both early ecotheology and new literature about the theology of eating.

    Wethe, P.I.

    1976-08-01

    In the beginning of the 1970s the public interest in nuclear power in Norway was negligible, and an active information campaign might have been interpreted as an attack on the dominant hydroelectric development policy. In 1973 the electricity authorities themselves began to propose concrete nuclear power projects. Over a very short interval of time organised protest groups emerged whose main objective was to hinder the establishment of nuclear power in their own districts. T hese have since developed into agressive national groups and in the period up to the spring of 1975 an intense press debate took place. The staff of Institutt for Atomenergi took an active part in this debate and this collection of articles and contributions gives an impression of the nuclear controversy in Norway from 1973 to 1976.

  7. Neural tube defects – recent advances, unsolved questions and controversies

    Science.gov (United States)

    Copp, Andrew J.; Stanier, Philip; Greene, Nicholas D. E.

    2014-01-01

    Neural tube defects (NTDs) are severe congenital malformations affecting around 1 in every 1000 pregnancies. Here we review recent advances and currently unsolved issues in the NTD field. An innovation in clinical management has come from the demonstration that closure of open spina bifida lesions in utero can diminish neurological dysfunction in children. Primary prevention by folic acid has been enhanced through introduction of mandatory food fortification in some countries, although not yet in UK. Genetic predisposition comprises the majority of NTD risk, and genes that regulate folate one-carbon metabolism and planar cell polarity have been strongly implicated. The sequence of human neural tube closure events remains controversial, but study of mouse NTD models shows that anencephaly, open spina bifida and craniorachischisis result from failure of primary neurulation, while skin-covered spinal dysraphism results from defective secondary neurulation. Other ‘NTD’ malformations, such as encephalocele, are likely to be post-neurulation disorders. PMID:23790957

    Keblinski, Pawel; Prasher, Ravi; Eapen, Jacob

    2008-01-01

    Over the last decade nanofluids (colloidal suspensions of solid nanoparticles) sparked excitement as well as controversy. In particular, a number of researches reported dramatic increases of thermal conductivity with small nanoparticle loading, while others showed moderate increases consistent with the effective medium theories on well-dispersed conductive spheres. Accordingly, the mechanism of thermal conductivity enhancement is a hotly debated topic. We present a critical analysis of the experimental data in terms of the potential mechanisms and show that, by accounting for linear particle aggregation, the well established effective medium theories for composite materials are capable of explaining the vast majority of the reported data without resorting to novel mechanisms such as Brownian motion induced nanoconvection, liquid layering at the interface, or near-field radiation. However, particle aggregation required to significantly enhance thermal conductivity, also increases fluid viscosity rendering the benefit of nanofluids to flow based cooling applications questionable.

    In an attempt to resolve the controversial issue of tectonic and hydrologic stability of the Yucca Mountain region, the National Academy of Sciences established a Panel on Coupled Hydrologic/Tectonic/HydrothermaI Systems. The Panel has recently released it's findings in a report entitled Ground Water at Yucca Mountain: How High Can It Rise? The representation of data and the scientific validity of this report was the subject of comprehensive evaluations and reviews which has led to correspondence between Dr. Charles Archarnbeau and Dr. Frank Press, the President of the National Academy of Sciences. All such correspondence prior to April 9, 1993 is covered by TRAC Special Report No. 5, open-quotes Dialogs on the Yucca Mountain Controversy.close quotes The present report represents a continuation of the dialog between Dr. Archambeau and Dr. Press; specifically the letter from Dr. Press to Dr. Archambeau dated April 9, 1993 and Archambeau's response to Press, dated August 19, 1993. In addition to the correspondence between Press and Archambeau, a series of recent reports by other investigators, referred to in the correspondence from Archambeau, are included in this report and document new data and inferences of importance for resolution of the question of suitability of the Yucca Mountain site as a high level nuclear waste repository. These reports also demonstrate that other scientists, not previously associated with the government's program at Yucca Mountain or the National Academy review of an aspect of that program, have arrived at conclusions that are different than those stated by the Academy review and DOE program scientists

  10. Mapping intravascular ultrasound controversies in interventional cardiology practice.

    Directory of Open Access Journals (Sweden)

    David Maresca

    Full Text Available Intravascular ultrasound is a catheter-based imaging modality that was developed to investigate the condition of coronary arteries and assess the vulnerability of coronary atherosclerotic plaques in particular. Since its introduction in the clinic 20 years ago, use of intravascular ultrasound innovation has been relatively limited. Intravascular ultrasound remains a niche technology; its clinical practice did not vastly expand, except in Japan, where intravascular ultrasound is an appraised tool for guiding percutaneous coronary interventions. In this qualitative research study, we follow scholarship on the sociology of innovation in exploring both the current adoption practices and perspectives on the future of intravascular ultrasound. We conducted a survey of biomedical experts with experience in the technology, the practice, and the commercialization of intravascular ultrasound. The collected information enabled us to map intravascular ultrasound controversies as well as to outline the dynamics of the international network of experts that generates intravascular ultrasound innovations and uses intravascular ultrasound technologies. While the technology is praised for its capacity to measure coronary atherosclerotic plaque morphology and is steadily used in clinical research, the lack of demonstrated benefits of intravascular ultrasound guided coronary interventions emerges as the strongest factor that prevents its expansion. Furthermore, most of the controversies identified were external to intravascular ultrasound technology itself, meaning that decision making at the industrial, financial and regulatory levels are likely to determine the future of intravascular ultrasound. In light of opinions from the responding experts', a wider adoption of intravascular ultrasound as a stand-alone imaging modality seems rather uncertain, but the appeal for this technology may be renewed by improving image quality and through combination with

    During the twentieth century it has been theorized that there is a link between musical achievement and academic achievement of young children. In support of this controversial view, many educators and music specialists promote the relationship between, parent, teacher, and child. The theory is: with cooperative learning experiences in the study…

    Full Text Available This paper studies the cultural change in science from academic science to post-academic science by the use of documentary studying and analytical reasoning. The aim of this study is determining the direction of cultural change in science and comparing it with cultural change in society.The knowledge production which surrounds academy has little relationship with the values of society and epistemological norms regulate scientists' behavior from within the scientific system. But in post-academic science the relationship between science and society operates in the same line with market and government and science produce within the social context and scientists' behavior controlled by the norms out of the scientific system. So the culture of science has changed because science applied to meet the requirements of market and industry. The result is that contrary to cultural change in society that goes from materialism to post-materialism, cultural change in science moves from post-materialism to materialism.

    2015-12-01

    Full Text Available Aims: An important aspect of the student’s learning in academic performance is self-regulating. Students without required academic achievement skills need educational approaches to obtain the required insight in self-regulate learning. The aim of this study was to determine the effects of teaching academic skills on academic achievement in the advanced diploma medical emergency students of Ilam University of Medical Sciences. Materials & Methods: The intervening pretest-posttest study without any control group was a section of a greater action-research study to conduct and implement an educational process. The intervention included two 3-hour educational workshops for ten academic skills at one month interval for 23 advanced diploma medical emergency students of Ilam University of Medical Sciences during their second educational semester in 2014. The study tool was a 10-phrase self-made questionnaire, its validity and reliability was confirmed. Data was analyzed in SPSS 21 software using Paired-T test. Findings: There was an increase in the mean total score of academic skills after the intervention (p=0.009. From ten skills, the differences between the mean scores before and after the intervention were significant only in academic planning skills (p=0.025, the utilization of the memory strengthening methods (p=0.045, and correct study techniques (p=0.031. Academic intervention affected the students’ academic achievement (GPA (p=0.001. Conclusion: Conducting academic skills educational workshops affects the utilization of the skills by the students and their academic achievements. 

  20. Current techniques in mammography

    Bohm, B.

    1982-01-01

    This paper represents a literature survey of current techniques in mammography. The major objection to the otherwise acceptable methods in widespread use are the radiation doses given the patient, particularly the asymptomatic patient. Even using current techniques which involve x-raying the breast, all women over 50 should have yearly exams for the earliest possible cancer detection and hence improved diagnosis. It is for asymptomatic women under 50 that the risk versus benefit issue becomes controversial. Strong efforts are being made to reduce or eliminate this dose. Current methods in widespread clinical use and experimental methods are briefly covered, and the recommendations of the National Council on Radiation Protection and Measurements (released July 1980) are stressed. The current experimental techniques which include NMR, ultrasound, thermography, computer tomography, heavy particle radiography and ionography are capsulized

  1. Brokered dialogue: A new research method for controversial health and social issues

    2012-07-01

    Full Text Available Abstract Background Dialogue is a foundational feature of social life and an important way in which we come to understand one another. In situations of controversy dialogue is often absent because of a range of social barriers. We have developed a new film-based qualitative research method for studying controversial issues in healthcare and social policy. We call this method Brokered Dialogue. Theoretically informed by the traditions in narrative inquiry and visual anthropology, the method is premised on the idea that dialogue possesses features making it unique as a generator of new knowledge and opportunities for social intervention. Film is not only an extraordinarily rich data source, but an excellent medium for knowledge transfer and dissemination. Discussion The paper introduces the Brokered Dialogue method. We outline its critical steps, including the procedures for sampling, data collection and data analysis of both textual and visual data. Participants in a Brokered Dialogue engage in filmed interviews that capture their perspectives on a given topic; they then share their perspectives with, and pose questions of, one another through the medium of film. Using a participatory editing process, only footage that participants feel comfortable showing to others is incorporated. This technique offers participants a ‘safe’ space for respectful interaction. The editing process itself is analytic, and the final assembly of footage approximates a dialogue on the topic at hand. A link to a film produced from a project piloting the method is provided to demonstrate its real world application. Summary Brokered Dialogue is a method for promoting respectful interactions among those with seemingly divergent views on a controversial topic and for discovering critical points of divergence that may represent pathways for improvement. While the end product is a ‘film’, the goal is to have these films used as catalysts for ongoing respectful

  2. Is the N170 face specific? Controversy, context, and theory

    Directory of Open Access Journals (Sweden)

    Brian D. Earp

    2013-04-01

    Full Text Available In cognitive science, there is an ongoing debate about the architecture of the mind: does it consist of a number of mental “organs” each managing a different function in isolation, or is it more of general processor, adaptable to a wide range of tasks? One corner of this debate has centered on face processing. This is because face-perception is crucial to normal human functioning and some evidence shows that faces may be processed by the brain in a privileged way compared to other types of stimuli. For example, in EEG brain recordings, the N170 is a characteristic signal that occurs after a participant is exposed to an image of a face, but it is much less pronounced when other stimuli are shown. More than 15 years of research on the “N170 face effect” have yielded the standard view that the N170 is at the very least face-sensitive, and possibly even face-specific, that is, indexing modular processes tied exclusively to facial geometries. The specificity claim is clearly stronger, and hence subject to significant controversy; while the more conservative “sensitivity” claim had been regarded (until recently as effectively settled. Nevertheless, Thierry and colleagues, in a contentious 2007 article, sought to undermine even this “conservative” consensus: they argued that the apparent face-responsiveness of the N170 in prior research was due to systematic flaws in experimental design. Fiery debate has followed. In this review, we put the debate in its historical and philosophical context, and try to spell out some of the theoretical and logical assumptions that underlie the claims of the competing camps. We then show that the best available evidence counts, at least partially, against the Thierry et al. construal of the N170. Accordingly, it would be premature to abandon the “conservative” account of the N170, according to which it is – minimally – responsive to faces. We conclude by returning to the more controversial claim

  3. The LNT-controversy and the concept of "controllable dose".

    Science.gov (United States)

    Kellerer, A M; Nekolla, E A

    2000-10-01

    There is no firm scientific information on the potential health effects, such as increased cancer rates, due to low doses of ionizing radiation. In view of this uncertainty ICRP has adopted as a prudent default option the linear no-threshold (LNT) assumption and has used it to derive nominal risk coefficients. Subsequent steps, such as the comparison of putative fatality rates in radiation workers with observed accident rates in other professions, have given the risk estimates a false appearance of scientific fact. This has encouraged meaningless computations of radiation-induced fatalities in large populations and has caused a trend to measure dose limits for the public not against the magnitude of the natural radiation exposure and its geographic variations, but against the numerical risk estimates. In reaction to this development, opposing claims are being made of a threshold in dose for deleterious health effects in humans. In view of the growing polarization, ICRP is now exploring a new concept "controllable dose" that aims to abandon the quantity collective dose, emphasizing, instead, individual dose and, in particular, the control of the maximum individual dose from single sources. Essential features of the new proposal are here examined, and it is concluded that the control of individual dose will still have to be accompanied by the avoidance of unnecessary exposures of large populations, even if their magnitude lies below that acceptable to the individual. If a reasonable cut-off at trivial doses is made, the collective dose can remain useful. Misapplications of collective dose are not the deeper cause of the current controversy; the actual root is the misrepresentation of the LNT-assumption as a scientific fact and the amplification of this confusion by loose terminology. If over-interpretation and distortion are avoided, the current system of radiation protection is workable and essentially sound, and there is no need for a fruitless LNT-controversy. The

  17. Sensory processing disorders – diagnostic and therapeutic controversies

    Directory of Open Access Journals (Sweden)

    Aneta R. Borkowska

    2017-09-01

    Full Text Available This article presents the current state of knowledge regarding the controversial issue of sensory integration dysfunction/sensory processing disorder. Symptoms are defined as impairments in the accurate reception and registering of stimuli, differentiation of stimulus intensity, and adequate reactivity to stimulation. They can be of specific character and occur in isolation and can also be a nonspecific element of a clinical picture of another disease entity. Psychophysiological and neuroimaging studies confirm the existence of both a distinct group of children with symptoms of sensory processing disorder diagnosed based on descriptions of behaviours listed in questionnaires and of a specific neurobiological basis of this disorder. In clinical practice, it is of key importance to determine whether behavioural problems observed in children are caused by disorders other than sensory processing disorders. Results of meta-analyses regarding sensory integration therapy are inconclusive and do not allow this form of treatment to be considered fact-based. Future studies with high methodological standards are necessary in order to verify the effectiveness of different forms of sensory integration therapy. Parents should be informed about the existing limitations.

    This overview covers a wide range of cannabis topics, initially examining issues in dispensaries and self-administration, plus regulatory requirements for production of cannabis-based medicines, particularly the Food and Drug Administration "Botanical Guidance." The remainder pertains to various cannabis controversies that certainly require closer examination if the scientific, consumer, and governmental stakeholders are ever to reach consensus on safety issues, specifically: whether botanical cannabis displays herbal synergy of its components, pharmacokinetics of cannabis and dose titration, whether cannabis medicines produce cyclo-oxygenase inhibition, cannabis-drug interactions, and cytochrome P450 issues, whether cannabis randomized clinical trials are properly blinded, combatting the placebo effect in those trials via new approaches, the drug abuse liability (DAL) of cannabis-based medicines and their regulatory scheduling, their effects on cognitive function and psychiatric sequelae, immunological effects, cannabis and driving safety, youth usage, issues related to cannabis smoking and vaporization, cannabis concentrates and vape-pens, and laboratory analysis for contamination with bacteria and heavy metals. Finally, the issue of pesticide usage on cannabis crops is addressed. New and disturbing data on pesticide residues in legal cannabis products in Washington State are presented with the observation of an 84.6% contamination rate including potentially neurotoxic and carcinogenic agents. With ongoing developments in legalization of cannabis in medical and recreational settings, numerous scientific, safety, and public health issues remain.

  19. Sustainable Development? Controversies over Prawn Farming on Mafia Island, Tanzania

    2016-01-01

    Full Text Available The world market for crustaceans has increased exponentially in recent years and so too have the number of production sites. However, the growth of this industry has not been without controversy, particularly regarding its environmental effects. In 2002, a large company based in Kenya applied to locate a prawn farm on Mafia Island, Tanzania, close to the Rufiji Delta. This scheme raised very differing views among various 'stakeholders': villagers living around the proposed site, the Mafia District Councillors (madiwan, government officials at varying levels, local and national activists (some in NGOs, the prawn farming company, and the experts whom they hired to produce environmental impact reports. There were opposing discourses around the rights of locals as citizens to retain control of 'their' resources, on the one hand, versus the needs of 'development' and the creation of jobs, on the other. There were also fierce debates about the importance and meaning of environment and sustainability, and the perceived role of corruption. This paper, based on fieldwork in 2002 and 2004, explores these complex debates and the ways in which the decision was finally made to allow the prawn farm to go ahead. It reveals the means by which the legal rights of citizens at the local level may be trumped by pressures emanating from those coming from above and outside who wield greater power.

  20. Zollinger-Ellison syndrome: classical considerations and current controversies.

    Science.gov (United States)

    Epelboym, Irene; Mazeh, Haggi

    2014-01-01

    Zollinger-Ellison syndrome (ZES) is an endocrinopathy characterized by gastrin-secreting tumors, responsible for causing the formation of multiple, refractory, and recurrent peptic ulcers in the distal duodenum and proximal jejunum. Two main variants have been described, sporadic and those found in association with parathyroid and pituitary tumors, a genetic disorder known as multiple endocrine neoplasia-1 (MEN-1). Biochemical serum evaluation for elevated gastrin, followed by radiological or nuclear localization of the primary lesion, is mandated for establishing diagnosis. The mainstays of treatment include management of hypersecretory state with medical suppression of gastric acid production and surgical resection of primary tumor for the prevention of malignant transformation and metastatic complications. Medical therapy with proton pump inhibitors has virtually eliminated the need for acid-reducing surgical procedures. Surgical approach to sporadic and MEN-1-associated ZES varies based on our understanding of the natural history of the condition and the probability of cure; however, resection to a negative microscopic margin is indicated in both cases. Postoperative surveillance involves measurement of gastrin level, followed by imaging if elevation is detected. Re-excision of recurrent or resection of metastatic disease is a subject of controversy; however, at the present time aggressive cytoreductive approach is favored.

    Succeeding theories and empirical investigations have often been built over conceptual understanding to develop talent education. Opportunities provided by society are crucial at every point in the talent-development process. Abilities differ and can vary among boys and girls. Although they have some responsibility for their own growth and development, the educational system and psychosocial variables influence on the successful development of high levels of education. This research explores students’ attitudes to science education to establish why many disengage with the subject in class and what can be done to reverse this trend to produce unimaginable scientific and practical benefits to society. The control group is students from several schools with traditional education in Iran and the experimental group is teams who have taken part in several activities such as national and international tournaments (2005-2013). This research has two parts: 1—how innovation in teaching and 2—discussion and controversy in class can improve science education and cause motivation. The average scores are divided into 5 ranges in both experimental and traditional groups. As shown by Spearman’s correlation rank (ρ) the difference between boys’ and girls’ average scores is about (2.71) in the control group but it has decreased to (0.29) in the experimental group. The main point of discussion is on problems in class which advance a set of interrelated scientific arguments for outstanding achievement.

  2. Understanding the nuclear controversy: An application of cultural theory

    2016-01-01

    The need for a secure and sustainable energy future has become firmly entrenched on the global political agenda. Governments worldwide are seeking solutions that will ensure security of their energy supplies, while reducing carbon emissions in the fight against climate change. Advocates of nuclear power have reframed the technology as the most reliable, cost-effective and immediate solution to both of these policy problems, and predicted the emergence of a 'nuclear renaissance’. However, there is little evidence to date that suggests a nuclear renaissance has actually taken place. Public opinion polling demonstrates that many remain unconvinced of the need for nuclear power. This paper uses Cultural Theory as a heuristic to understand why the arguments for a nuclear renaissance have been largely unsuccessful. It argues that the failure of nuclear advocates to engage with a wider cross-section of world-views has prevented the controversy surrounding nuclear power from being resolved, and the nuclear renaissance from becoming a reality. In doing so, this paper builds upon a growing recognition of the contribution that social science research can make to understanding public acceptance of energy policy choices. - Highlights: • There is little evidence of a nuclear renaissance taking place in Western Europe or North America. • Public opinion on nuclear power continues to be deeply divided. • Pro-nuclear arguments are dominated by a particular cultural rationality. • A broader range of cultural perspectives needs to be recognised for the nuclear debate to progress.

  3. Controversies, development and trends of biofuel industry in the world

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Controversies, development and trends of biofuel industry in the world were discussed in present article. First-generation biofuels, i.e., grain and land based biofuels, occupied large areas of arable lands and severely constrained food supplies, are widely disputed. They have been replaced by second-generation biofuels. The raw materials of the second-generation biofuels include plants, straw, grass and other crops and forest residues. However, the cost for production of the second-generation biofuels is higher. Therefore the development of the third-generation biofuels is undergoing. The third-generation technologies use, mainly algae, as raw material to produce bioethanol, biobutanol, biodiesel and hydrogen, and use discarded fruits to produce dimethylfuran, etc. Different countries and regions are experiencing different stages of biofuel industry. In the future the raw materials for biofuel production will be focused on various by-products, wastes, and organisms that have not direct economic benefit for human. Production technologies should be improved or invented to reduce carbon emission and environmental pollution during biofuel production and to reduce production cost.

  4. The Soul in Medicine: Rabbinic and Scientific Controversies.

    Science.gov (United States)

    Zukier, Henri

    2016-12-01

    The practice of medicine relies on a combination of two very different sources, and requires two kinds of talents: a cognitive-instrumental, knowledge-based and disease-centered approach; and a psychological, expressive-relational and patient-centered approach. Throughout the centuries, the mix between the cognitive and expressive dimensions, and the relative emphasis given to each approach, has varied considerably. Current evidence-based medicine privileges the cognitive-performative dimension. The recent developments within medicine are indicative of the inherent and lasting tension between the cognitive and expressive dimensions. Not surprisingly, then, related terms of debate are also apparent in medieval rabbinic discussions of medical practice. However, the rabbinic and medical traditions resolved the tension in very different ways. This paper explores a conceptual link between the modern dynamics of the cognitive and the socio-relational dimensions, and a complementary rabbinic controversy starting in the thirteenth century, originally between Maimonides and Nahmanides, both physicians. There are significant interactions between the modern evolution in the roles of doctors and patients, and the rabbinic approaches to physicians and illness. The mapping of the two debates about doctors and patients suggests that the tension between science and soul, and the dynamics of integrating them, has characterized medicine through the ages, though they can lead to different outcomes.

    2016-12-01

    The US Food and Drug Administration (FDA) approved 10 new drugs for the treatment of multiple myeloma (MM) over the last two decades. The influx of new anti-myeloma agents with high efficacy and acceptable tolerability add complexity to the clinical decision-making process. First, treatment of smoldering multiple myeloma (SMM) remains investigational to date, although a randomized trial showed a survival gain in high-risk patients receiving lenalidomide. Second, in newly diagnosed MM, the majority of contemporary induction regimens have been studied in single-arm trials or compared to an older regimen, which complicates evidence-based treatment selection. Third, the role of consolidation chemotherapy followed by autologous stem cell transplant (ASCT) needs to be revisited in the context of highly effective agents, as newer regimens- such as carfilzomib, lenalidomide, and dexamethasone-are able to achieve extremely deep responses equivalent to or exceeding those seen after conventional induction and ASCT. Fourth, risks and benefits of maintenance therapy should also be redefined and individualized, as long-term survival and safety data accumulate. Here we selected four clinical settings where controversies exist, reviewed evidences behind conflicting treatment strategies, and asked myeloma experts to discuss evidence-based recommendations.

  6. Adiponectin as a Biomarker of Osteoporosis in Postmenopausal Women: Controversies

    Directory of Open Access Journals (Sweden)

    Anna Lubkowska

    2014-01-01

    Full Text Available The literature reports indicating a link between plasma levels of adiponectin and body fat, bone mineral density, sex hormones, and peri- and postmenopausal changes, draw attention to the possible use of adiponectin as an indicator of osteoporotic changes, suggesting that adiponectin may also modulate bone metabolism. In this study, we attempted to analyze the available in vitro and in vivo results which could verify this hypothesis. Although several studies have shown that adiponectin has an adverse effect on bone mass, mainly by intensifying resorption, this peptide has also been demonstrated to increase the proliferation and differentiation of osteoblasts, inhibit the activity of osteoclasts, and reduce bone resorption. There are still many ambiguities; for example, it can be assumed that concentrations of adiponectin in plasma do not satisfactorily reflect its production by adipose tissue, as well as conflicting in vitro and in vivo results. It seems that the potential benefit in the treatment of patients with osteoporosis associated with the pharmacological regulation of adiponectin is controversial.

  7. ACCOUNTING CONTROVERSY ON THE RECOGNITION AND EVALUATION OF DEVELOPMENT EXPENDITURE

    Directory of Open Access Journals (Sweden)

    TULVINSCHI MIHAELA

    2017-12-01

    Full Text Available The development of technology in recent decades has forced the transition from the industrialized society, where the main role was occupied by tangible assets, to an information society, where the essential place is played by intangible assets. These are assets that can not be touched or felt, but are very important to produce wealth and to maintain competitiveness. Within these, development expenditure occupies an important place because it influences the analysis of an entity and its future. The accounting practices applicable to development expenditure are based on theoretical fundamentals and ambiguous typologies. The purpose of the article is to present the controversies about recognizing and evaluating development expenditure. Although development expenditure involves large initial investments, it generates, on medium and long term, significant savings. Depending on the purpose for which it is carried out, research and development expenditure can in time generate identifiable intangible assets but also intangible unidentifiable assets. An optimistic attitude regarding the chances of success of a development project will lead to the capitalization of development expenditure. Capitalizing development expenditures, the usefulness of financial statements is increased, which is generally measured in the ability to explain stock prices through earnings and accounting values.

  8. Three controversies over item disclosure in medical licensure examinations

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available In response to views on public's right to know, there is growing attention to item disclosure – release of items, answer keys, and performance data to the public – in medical licensure examinations and their potential impact on the test's ability to measure competence and select qualified candidates. Recent debates on this issue have sparked legislative action internationally, including South Korea, with prior discussions among North American countries dating over three decades. The purpose of this study is to identify and analyze three issues associated with item disclosure in medical licensure examinations – 1 fairness and validity, 2 impact on passing levels, and 3 utility of item disclosure – by synthesizing existing literature in relation to standards in testing. Historically, the controversy over item disclosure has centered on fairness and validity. Proponents of item disclosure stress test takers’ right to know, while opponents argue from a validity perspective. Item disclosure may bias item characteristics, such as difficulty and discrimination, and has consequences on setting passing levels. To date, there has been limited research on the utility of item disclosure for large scale testing. These issues requires ongoing and careful consideration.

  9. [Parental alienation and the controversy surrounding psychiatric diagnostics].

    Migchels, C; De Wachter, D

    The phenomenon of parental alienation can arise when a child allies with one parent and refuses to have contact with the other parent. The concept has attracted a great deal of attention over the last few years. There has been controversy about whether parental alienation should be recognised as a psychiatric syndrome of the alienated child caught up in a conflict between supporters and opponents. AIM: To try to determine whether parental alienation belongs to psychiatric diagnostics. METHOD: We made a careful study of various databases in order to find literature relating to parental alienation. RESULTS: Parental alienation is situated on the border between psychiatry, sociology and justice. One of the main tasks of psychiatry in this border area is to safeguard the domain of diagnostics. CONCLUSION: Because so much attention is being given to the question of whether parental alienation syndrome should be recognised as a diagnosis, there is often a tendency to ignore the possible impact of parental alienation and to pay very little attention to ways of coping with the problem.

  10. Outbreaks associated with duodenoscopes: new challenges and controversies.

    2016-08-01

    Recent outbreaks of carbapenem-resistant enterobacteriaceae related to duodenoscopes in the United States and Europe have gained international attention and resulted in new regulations, especially in the United States, affecting healthcare facilities. In this review, we summarize findings from recent duodenoscope-related outbreaks, highlight what is known about the risk of transmission from these devices and discuss controversies about current recommendations to prevent transmission. Between 2013 and 2015, several US and European healthcare facilities reported outbreaks of carbapenem-resistant enterobacteriaceae associated with endoscopic retrograde cholangiopancreatography procedures. Unlike prior outbreaks (attributed to lapses in cleaning and reprocessing), the recent outbreaks occurred in spite of adherence to current reprocessing guidelines. Factors associated with infection transmission include a low margin of safety for gastrointestinal endoscopic procedures and complex design features of duodenoscopes. Outbreaks were halted with enhanced cleaning and surveillance measures or by adopting gas sterilization methods. New guidance from manufacturers and federal agencies has been issued as a result of these recent outbreaks; however, concerns remain that the new measures may not eliminate risks to patients. Recent duodenoscope-related outbreaks have highlighted the need for a reassessment of current guidelines for endoscope reprocessing and for new design of duodenoscope components. Although we summarize the US experience, this review has global implications for the safe cleaning and disinfection of these instruments.

  11. Roles of glucocorticoids in human parturition: a controversial fact?

    Science.gov (United States)

    2014-05-01

    The pivotal role of glucocorticoids in the initiation of parturition has been very well documented in several domestic mammalian animal species. However the role of glucocorticoids in human parturition remains controversial mainly because of the absence of effect of synthetic glucocorticoids, given to promote fetal organ maturation in pregnant women with threatened preterm delivery, on the length of gestation. This article will review studies of glucocorticoids in human parturition and provide evidence for an important role of glucocorticoids in human parturition as well but a simultaneous high concentration of estrogen within the intrauterine tissues may be necessary for GCs to initiate parturition. The synthetic GCs dexamethasone and betamethasone pass through the placenta intact resulting in potent negative feedback on the fetal HPA axis and diminished production of DHEA from fetal adrenal glands for estrogen synthesis by the placenta. This may negate the effect of systemic administration of GCs on the induction of labor, especially in cases where the myometrium is not yet fully primed by estrogen. Endogenous glucocorticoids are inactivated by the placental 11β-HSD2 thus limiting the negative feedback of maternal cortisol on the fetal HPA axis and allowing the simultaneous rise of cortisol and estrogen levels towards the end of gestation. Therefore, endogenous glucocorticoids, particularly glucocorticoids produced locally in the intrauterine tissues may play an important role in parturition in humans by enhancing prostaglandin production in the fetal membranes and stimulating estrogen and CRH production in the placenta.

    In the years following the hepatitis B vaccination/multiple sclerosis controversy, a number of new issues regarding vaccine safety have been raised, in some cases leading to more debate and confusion. Against this background, an international group of experts was convened to review the current points of view concerning the use of thimerosal as a preservative and its potential risks; the suggested link between thimerosal-containing vaccines and acute lymphoblastic leukemia; the alleged association between aluminum-containing vaccines/macrophagic myofasciitis and general systemic complaints; a possible link between vaccination and autoimmune pathology; and a hypothetical link between measles-mumps-rubella vaccination and autism. At present, there are no data to conclude that childhood vaccines, and in particular hepatitis B vaccine, pose a serious health risk or justify a change in current immunization practice. However, vaccine "scares" continue to have an international impact on immunization coverage. Creating a positive environment for immunization can be achieved by repositioning the value of vaccines and vaccination, supported by evidence-based information. The role of international organizations, the media, and the industry in the implementation of communication strategies was discussed and the impact of litigation issues on vaccination was evaluated. The Viral Hepatitis Prevention Board confirms its commitment to current recommendations for universal and risk group hepatitis B vaccination and further encourages the conduct of vaccine safety studies and the dissemination of their results.

    This overview covers a wide range of cannabis topics, initially examining issues in dispensaries and self-administration, plus regulatory requirements for production of cannabis-based medicines, particularly the Food and Drug Administration “Botanical Guidance.” The remainder pertains to various cannabis controversies that certainly require closer examination if the scientific, consumer, and governmental stakeholders are ever to reach consensus on safety issues, specifically: whether botanical cannabis displays herbal synergy of its components, pharmacokinetics of cannabis and dose titration, whether cannabis medicines produce cyclo-oxygenase inhibition, cannabis-drug interactions, and cytochrome P450 issues, whether cannabis randomized clinical trials are properly blinded, combatting the placebo effect in those trials via new approaches, the drug abuse liability (DAL) of cannabis-based medicines and their regulatory scheduling, their effects on cognitive function and psychiatric sequelae, immunological effects, cannabis and driving safety, youth usage, issues related to cannabis smoking and vaporization, cannabis concentrates and vape-pens, and laboratory analysis for contamination with bacteria and heavy metals. Finally, the issue of pesticide usage on cannabis crops is addressed. New and disturbing data on pesticide residues in legal cannabis products in Washington State are presented with the observation of an 84.6% contamination rate including potentially neurotoxic and carcinogenic agents. With ongoing developments in legalization of cannabis in medical and recreational settings, numerous scientific, safety, and public health issues remain. PMID:27683558

  14. Gender dysphoria and the controversy over the Safe Schools program.

    The Safe Schools program has attracted great controversy. On one end of the spectrum, it is defended as an anti-bullying program for young people who identify themselves as gay or lesbian, or have issues concerning their gender identity. On the other end of the spectrum, it is regarded as social engineering. This article seeks to promote a discussion of the way in which gender identity issues are addressed in the Safe Schools program. It is argued that the information in this program to Principals, teachers and young people is inaccurate and misleading. The program, as presently designed, may actually cause harm to children and young people who experience gender identity issues because it promotes gender transitioning without expert medical advice. The Safe Schools materials do not acknowledge that the great majority of children resolve gender dysphoria issues around the time of puberty. It may be much more difficult for a child to accept his or her gender at puberty if he or she has already changed name and gender identity in primary school. These deficits need to be addressed if the program is to continue.

    Aims To review three key and controversial comorbidities of cannabis use – other illicit drug use, psychosis and depression as well as suicide, from a genetically informed perspective. Design Selective review. Results Genetic factors play a critical role in the association between cannabis use, particularly early-onset use and use of other illicit drugs, psychosis and depression as well as suicide, albeit via differing mechanisms. For other illicit drugs, while there is strong evidence for shared genetic influences, residual association that is attributable to causal or person-specific environmental factors cannot be ruled out. For depression, common genetic influences are solely responsible for the association with cannabis use but for suicidal attempt, evidence for person-specific factors persists. Finally, even though rates of cannabis use are inordinately high in those with psychotic disorders, there is no evidence of shared genetic etiologies underlying this comorbidity. Instead, there is limited evidence that adolescent cannabis use might moderate the extent to which diathesis influences psychosis. Conclusions Overlapping genetic influences underlie the association between early-onset cannabis use and other illicit drug use as well as depression and suicide. For psychosis, mechanisms other than shared genetic influences might be at play. PMID:24438181

    This supplement reports proceedings of the second international Global Urticaria Forum, which was held in Berlin, Germany in November 2015. Despite the clear international guideline, there remain a number of controversies and challenges in the management of patients with chronic urticaria (CU). As a result of major advancements in urticaria over the past 4 years, the current EAACI/GA(2) LEN/EDF/WAO urticaria guideline treatment algorithm requires updating. Case studies from patients with chronic spontaneous urticaria (CSU) [also called chronic idiopathic urticaria (CIU)], chronic inducible urticaria (CIndU) or diseases and syndromes related to CU are useful in describing and exploring challenges in disease management. Case studies of specific CSU patient populations such as children with CU or patients with angio-edema but no hives also require consideration as potentially challenging groups with unmet needs. The current EAACI/GA(2) LEN/EDF/WAO urticaria guideline provides a general framework for the management of patients with CU but, as these cases highlight, a personalized approach based on the expert knowledge of the physician may be required. © 2016 European Academy of Dermatology and Venereology.

    Full Text Available This article analyses the multiple dimensions of Austria’s Europeanisation and the high degree of both misfit and conflict involved therein. Austria’s path to EU membership was characterised by fundamental doubts due to the country’s status of neutrality, and by a basic reinterpretation of this concept. After accession, need for institutional adaptation to the EU’s decision-making patterns was significant since major tenets of the Austrian political system are special. Furthermore, policy misfit between the domestic and the EU level was considerable in several fields, among them highly symbolic ones. Austria’s EU-related diplomacy recently witnessed a major crisis with the other 14 member states ‘sanctioning’ the new centre-right government in a controversial way. Against this background of strong and multi-dimensional misfit, Austrian performance in implementing EU law is still surprisingly good. By contrast, public appreciation of EU membership has declined even further, and a majority of Austrians oppose enlargement while the Freedom Party advocates a referendum on that issue. Therefore, the conclusions argue that improved communication processes and mutual learning across the multiple levels of the EU system are crucial.

  19. Asbestos and cancer: epidemiological and public health controversies.

    Huncharek, M

    1994-01-01

    This paper discusses many of the currently controversial issues surrounding asbestos health effects and their relationship to cancer risk assessment and risk management. The major conclusions reached from this analysis are: (1) All asbestos fiber types are carcinogenic and pose a threat to human health. Therefore, all fiber types should be regulated similarly. (2) The health risks associated with indoor asbestos exposure are uncertain. Available data show that some groups, such as building maintenance personnel (among others), may contract asbestos-related diseases secondary to indoor exposure. Clearly, additional research is needed to accurately determine the extent and nature of disease risk under these conditions. (3) Controlled use has proved an elusive goal. Limited information from underdeveloped countries parallels the experience of Western industrialized nations. Efforts by the Canadian government to establish markets for asbestos in these areas should be opposed. (4) Finally, asbestos-related cancer risk is no longer confined to asbestos industry workers. Asbestos-related mesothelioma has been documented in a wide variety of occupational and nonoccupational settings, highlighting the need for continued surveillance to minimize potential health risks.

    The link between maternal obesity and inflammatory mediators is still unclear. Our aim was to summarize the main findings of recently published studies on this topic. We performed a search in Medline for studies published in the last years on obesity, human pregnancy, and inflammatory mediators. We report the findings of 30 studies. The characteristics and number of participants, study design, gestational age at sample collection, and type of sample varied widely. Approximately two-thirds of them investigated more than one mediator, and 50% included participants in only one trimester of pregnancy. The most frequently investigated mediators were leptin, tumour necrosis factor-alpha (TNF-α), and interleukin (IL)-6. Almost all studies reported an association between maternal obesity, leptin, and C-reactive protein (CRP) serum levels but not with IL-1β and IL-10. The association of IL-6, TNF-α, monocyte chemo-attractant protein-1 (MCP-1), adiponectin, and resistin with maternal obesity is still controversial. To clarify the physiopathological link between maternal obesity and inflammation, more high-quality studies are needed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A review of articles published since January 2012 on the topic of cord blood banking and cord blood stem cell transplantation was conducted for this the 25th anniversary year of the first cord blood transplant performed in a human. Cord blood banking is performed throughout the world. Umbilical cord blood (UCB) transplantation is recognized as an acceptable alternative stem cell source for paediatric and adults requiring a haematopoietic transplant, particularly for patients of racial and ethnic minorities. To further advance the use of UCB, methods to enhance UCB stem cell expansion, engraftment and maintenance may be required. Controversy on the most effective and economically sustainable model for banking and storing an optimal UCB product continues to persist. Cord blood banking and transplantation of cord blood stem cells has advanced rapidly over the initial 25 years, as more than 30 ,000 patients have benefited from the therapy. New concepts on the use of methods to expand UCB stem cells for transplantation and use for nonhaematopoietic indications may increase demand for UCB over the next few decades.

    Can the carcinogenic risks of radiation that are observed at high doses be extrapolated to low doses? This question has been debated through the whole professional life of the author-now nearing four decades. In its extreme form the question relates to a particular hypothesis (LNT) used widely by the international community for radiological protection applications. The linear no-threshold (LNT) hypothesis propounds that the extrapolation is linear and that it extends down to zero dose. The debate on the validity of LNT has increased dramatically in recent years. This is in no small part due to concern that exaggerated risks at low doses leads to undue amounts of societal resources being used to reduce man-made human exposure and because of the related growing public aversion to diagnostic and therapeutic medical exposures. The debate appears to be entering a new phase. There is a growing realisation of the limitations of fundamental data and the scientific approach to address this question at low doses. There also appears to be an increasing awareness that the assumptions necessary for a workable and acceptable system of radiological protection at low doses must necessarily be based on considerable pragmatism. Recent developments are reviewed and a historical perspective is given on the general nature of controversies in radiation protection over the years. All the protagonists in the debate will at the end of the day probably be able to claim that they were right{exclamation_point} (opinion)

    Changes or introductions of technology or equipment can affect how a sport is played or influence its performances. This article conducted a systematic review of peer-reviewed literature to identify any case studies of controversial events surrounding the implementation or use of sports technology. 56 articles were identified that highlighted 31 different case studies found over a three decade time period. Thematic analysis revealed six distinctive themes when reviewing the articles. Whilst the sport of golf had the highest number of case studies, it was found that a significant level of attention had been recorded in the cases of Oscar Pistorius use of prosthetic legs in athletics and the use of full length swimsuits in swimming. The trend surrounding the number of articles was shown to be initially intermittent but saw a peak period from 2008 to 2010. However, the frequency of such articles since this peak has been more consistent. It is proposed that long periods of time without intervention or resolution by a governing body often increases the peer-reviewed attention paid to such cases in examples such as those identified in this systematic review.

  7. Ethical controversies in organ donation after circulatory death.

    Science.gov (United States)

    2013-05-01

    The persistent mismatch between the supply of and need for transplantable organs has led to efforts to increase the supply, including controlled donation after circulatory death (DCD). Controlled DCD involves organ recovery after the planned withdrawal of life-sustaining treatment and the declaration of death according to the cardiorespiratory criteria. Two central ethical issues in DCD are when organ recovery can begin and how to manage conflicts of interests. The "dead donor rule" should be maintained, and donors in cases of DCD should only be declared dead after the permanent cessation of circulatory function. Permanence is generally established by a 2- to 5-minute waiting period. Given ongoing controversy over whether the cessation must also be irreversible, physicians should not be required to participate in DCD. Because the preparation for organ recovery in DCD begins before the declaration of death, there are potential conflicts between the donor's and recipient's interests. These conflicts can be managed in a variety of ways, including informed consent and separating the various participants' roles. For example, informed consent should be sought for premortem interventions to improve organ viability, and organ procurement organization personnel and members of the transplant team should not be involved in the discontinuation of life-sustaining treatment or the declaration of death. It is also important to emphasize that potential donors in cases of DCD should receive integrated interdisciplinary palliative care, including sedation and analgesia.

    2014-01-01

    The cancer stem cell (CSC) model is based on a myriad of experimental and clinical observations suggesting that the malignant phenotype is sustained by a subset of cells characterized by the capacity for self-renewal, differentiation and innate resistance to chemotherapy and radiation. CSC may be responsible for disease recurrence after definitive therapy and may therefore be functionally synonymous with minimal residual disease. Similar to other solid tumours, several putative surface markers for lung CSC have been identified, including CD133 and CD44. In addition, expression and/or activity of the cytoplasmic enzyme aldehyde dehydrogenase ALDH and capacity of cells to exclude membrane permeable dyes (known as the ‘side population’) correlate with stem-like function in vitro and in vivo. Embryonic stem cell pathways such as Hedgehog, Notch and WNT may also be active in lung cancers stem cells and therefore may be therapeutically targetable for maintenance therapy in patients achieving a complete response to surgery, radiotherapy or chemo-therapy. This paper will review the evidence regarding the existence and function of lung CSC in the context of the experimental and clinical evidence and discuss some ongoing controversies regarding this model.

  9. Intestinal Neuronal Dysplasia Type B in Adults: A Controversial Entity

    2014-01-01

    Full Text Available Intestinal neuronal dysplasia (IND is a well-defined entity which raises controversy among authors, described as a congenital malformation of gastrointestinal innervation and caused by dysplastic embryonal development of the enteric nervous system. It is potentially associated with mild and chronic gastrointestinal motility disturbances. IND is rarely reported in adults and especially elderly patients. The present study reports on the case of a 71-year-old man suffering from longstanding idiopathic constipation and who was misdiagnosed for more than 60 years, despite several hospital admissions and a sigmoidectomy in the meantime. On the last admission, the patient presented with megacolon, abdominal pain and X-ray finding of bowel obstruction. Due to massive large bowel dilatation, an exploratory laparotomy failed to reveal any obvious mechanical cause, and a subtotal colectomy and Hartmann's procedure was performed. Bowel continuity was performed 3 months later. Analysis of full-thickness biopsies revealed enlarged myenteric and submucosal neurons as well as an increased number of giant cells and increased acetylcholinesterase activity in the mucosa. The diagnosis of IND was established. The main diagnostic criteria, the underlining pathophysiology and the recommended therapeutic approach of this rare entity are extensively reviewed.

  10. Emerging from the rib: resolving the turtle controversies.

    Rice, Ritva; Riccio, Paul; Gilbert, Scott F; Cebra-Thomas, Judith

    2015-05-01

    Two of the major controversies in the present study of turtle shell development involve the mechanism by which the carapacial ridge initiates shell formation and the mechanism by which each rib forms the costal bones adjacent to it. This paper claims that both sides of each debate might be correct-but within the species examined. Mechanism is more properly "mechanisms," and there is more than one single way to initiate carapace formation and to form the costal bones. In the initiation of the shell, the rib precursors may be kept dorsal by either "axial displacement" (in the hard-shell turtles) or "axial arrest" (in the soft-shell turtle Pelodiscus), or by a combination of these. The former process would deflect the rib into the dorsal dermis and allow it to continue its growth there, while the latter process would truncate rib growth. In both instances, though, the result is to keep the ribs from extending into the ventral body wall. Our recent work has shown that the properties of the carapacial ridge, a key evolutionary innovation of turtles, differ greatly between these two groups. Similarly, the mechanism of costal bone formation may differ between soft-shell and hard-shell turtles, in that the hard-shell species may have both periosteal flattening as well as dermal bone induction, while the soft-shelled turtles may have only the first of these processes. © 2015 Wiley Periodicals, Inc.

  17. Academic freedom and the obligation to ensure morally responsible scholarship in nursing.

    Johnstone, Megan-Jane

    2012-06-01

    Academic freedom is generally regarded as being of critical importance to the development, improved understanding, and dissemination of new knowledge in a field. Although of obvious importance to the discipline of nursing, the nature, extent and value of academic freedom and the controversies surrounding it have rarely been considered in the nursing literature. It is a key aim of this paper to redress this oversight by providing a brief examination of: (i) the principle of academic freedom; (ii) the distinction between academic freedom, freedom of speech, and the academic freedom to publish; (iii) the problem of ideological judgments being dressed up as scientific or discipline judgments to supports 'bad' conclusions; and (iv) the standards that might otherwise be appealed to for determining whether maverick manuscripts supporting morally abhorrent conclusions should be accepted for publication. It is suggested that the tenets of academic freedom require robust international debate, with due attention being given to such issues as the development of an international declaration on academic freedom to publish in nursing, how to ensure a robust rebuttal system in nursing journals to counter specious scholarship, and how to better promote the letters pages of nursing journals as a venue for facilitating debate on controversial issues. © 2011 Blackwell Publishing Ltd.

    Infectious diseases caused by multi-resistant pathogens are increasing worldwide and are posing a challenge to German urology as well. Furthermore, there is a limited perspective of new antibiotic developments. One way out of this dilemma is a differentiated handling and use of antibiotics (antibiotic stewardship, ABS). The aim of this review is to identify key issues in modern urological antibiotic therapy, which can be considered as exemplary for the whole topic of ABS. This includes a review of the current data of the individual topics, including thought-provoking impulse for future clinical application and research. The research group "infectious diseases" of GeSRU Academics identified the following central topics: excessive use of fluoroquinolones, diagnosis and treatment of urethritis and perioperative antibiotic prophylaxis. Subsequently, we performed a literature research in MEDLINE to uncover controversies and open questions of the individual topics within the meaning of ABS. The analysis of modern antibiotic therapy in urology shows numerous open questions in all quality dimensions of ABS: structural quality (e.g. through improved training of medical staff in the differentiated use of antibiotics), process quality (e.g. by improved adherence to existing infectiological guidelines, here in particular the perioperative prophylaxis and therapy of urethritis) and outcome (e.g. by detection of resistance rates and infection rates). The overarching and common goal is to avoid a post-antibiotic era. ABS programmes and a 10-point plan of the federal government are considered positive political developments in this area but do not release the individual urologist from a personal responsibility as part of his daily routine. A critical analysis of the topic "antibiotic treatment" is essential.

  1. [Neuroethics and bioethics--implications of Balkanization controversy].

    Science.gov (United States)

    Kagawa, Chiaki

    2009-01-01

    There have been considerable disputes the positioning of neuroethics as a new field since its emergence in 2002. It is the novelty of the neuroethical issues and the necessity for updated moral approaches to them that leading exponents of neuroethics have emphasized; advances in neurosciences have created an entirely new field of moral inquiries that the conventional bioethics had never noticed. Futher, as neuroethics embraces the subdivision of ethics in neuroscience, it should take precedence over bioethics, which depends on the fundamental moral concepts without questioning their bases. Many bioethicists have squarely opposed these insistences and thereby detected the claim of neuroethics exceptionalism: the asserted newness of issues comes mainly from the ignorance of exponents of this new field regarding accumulated bioethical inquiries, so that the overlapping concerns between bioethics and neuroethics are passed on to the future by them. Moreover, bioethicists point out that the recent tendency of Balkanization in the field of bioethics could endanger the integrity of moral investigations. Subfields of bioethics, such as geneethics, neuroethics, nanoethics and so on, originate consecutively, entail wastage of valuable time and money, and increase the risk of fragmentizing moral considerations in an inconsistent way. By reviewing this controversy between neuroethics and bioethics, I argue that the relevant scientific investigations and technologies, which have appeared to promote the proliferation of bioethical sub-disciplines to date, are beginning to converge into 1 complex that demands not the division into subspecialities but the novel integration of bioethical inquiries: it is time to attempt the unification of bioethical applied ethics for moral considerations regarding nano-bio-info-cogno convergent technologies.

  2. Management of ß-thalassemia – Consensus and controversies!

    Full Text Available The mainstay of treatment of ß-Thalassemia major includes life-long regular packed red cell transfusions and iron chelation. With advances in understanding the molecular biology and its implications in the patients, newer modalities are now being explored to offer a better quality of life to transfusion dependent thalassemic patients. Improved safety of transfusions, newer chelator drugs and combination of chelators have improved outcomes in these patients. Amlodipine along with chelators may be a future option for preventing cardiac iron overload related complications. Drugs which improve HbF levels and thus ameliorate anemia such as hydroxyurea, butyrates azacytidine etc. have also been explored with little relief to transfusion dependent patients. HSCT, which is the only curative treatment available at present, has its own limitations as sibling donors may not be available to many. However, there has been extensive work done on improving outcomes with MUD and Haplo-identical HSCT in the recent times. Gene therapy using lentiviral vectors is also offering great hope to these children. Induced Pluripotent Stem Cells (iPSC is a promising advance in the treatment of thalassemia. Several newer molecules targeting different pathophysiologic aspects are being explored and have met with good success. These include luspatercept, sotatercept, macrophage inhibition, JAK2 inhibition using ruxolitinib etc. Controversies regarding use of wheat grass and ESAs are relatively less worrisome. But use of thalidomide should be done with great caution. Despite its success reported in anecdotal reports, in the absence of adequate data with larger trials, its role in routine management of thalassemia syndromes remains to be ascertained.

  3. 25 Years of Self-organized Criticality: Concepts and Controversies

    Science.gov (United States)

    Watkins, Nicholas W.; Pruessner, Gunnar; Chapman, Sandra C.; Crosby, Norma B.; Jensen, Henrik J.

    2016-01-01

    Introduced by the late Per Bak and his colleagues, self-organized criticality (SOC) has been one of the most stimulating concepts to come out of statistical mechanics and condensed matter theory in the last few decades, and has played a significant role in the development of complexity science. SOC, and more generally fractals and power laws, have attracted much comment, ranging from the very positive to the polemical. The other papers (Aschwanden et al. in Space Sci. Rev., 2014, this issue; McAteer et al. in Space Sci. Rev., 2015, this issue; Sharma et al. in Space Sci. Rev. 2015, in preparation) in this special issue showcase the considerable body of observations in solar, magnetospheric and fusion plasma inspired by the SOC idea, and expose the fertile role the new paradigm has played in approaches to modeling and understanding multiscale plasma instabilities. This very broad impact, and the necessary process of adapting a scientific hypothesis to the conditions of a given physical system, has meant that SOC as studied in these fields has sometimes differed significantly from the definition originally given by its creators. In Bak's own field of theoretical physics there are significant observational and theoretical open questions, even 25 years on (Pruessner 2012). One aim of the present review is to address the dichotomy between the great reception SOC has received in some areas, and its shortcomings, as they became manifest in the controversies it triggered. Our article tries to clear up what we think are misunderstandings of SOC in fields more remote from its origins in statistical mechanics, condensed matter and dynamical systems by revisiting Bak, Tang and Wiesenfeld's original papers.

  4. Controversy in the management of optic nerve glioma

    1987-01-01

    The records of 16 patients with optic nerve glioma treated between 1961 and 1984 were reviewed. All patients except two had extension of tumor beyond the chiasm to the hypothalamus, adjacent brain and/or along the posterior optic tract. Eleven of 16 cases were biopsy-proven, two patients had craniotomy and visual inspection but no biopsy was performed, and in two cases the biopsy was not diagnostic. Fourteen patients received radiation therapy, usually consisting of 50 Gy in 5 weeks (range 40-56 Gy), one patient was treated surgically and one with chemotherapy. With a follow-up of 1 to 20 years, 7 of the 14 patients irradiated are alive, three patients are dead of disease at 3, 6 and 9 years post-treatment, three were lost to follow-up at 1, 8, and 8 years, and one is dead of intercurrent disease at 5.5 years. Overall vision was improved in five patients and stable in seven following treatment. In two patients, vision could not be evaluated because of young age at presentation. Four patients had recurrences. One was retreated with 30 Gy in 3 weeks and shows no evidence of disease at 20 years. The three other patients died of their disease. There is controversy over the best treatment for these patients. Based on these results and a review of the literature, the authors recommendation is to irradiate tumors with extension beyond the chiasm at the time of presentation rather than waiting for increasing symptoms because function that is lost may not always be recovered. Chemotherapy needs to be further investigated but holds promise, especially for the younger children

    Safe placement of the Verres needle or the primary trocar for establishment of pneumoperitoneum is the most critical step in laparoscopic procedure as it is associated with bowel, bladder and life threatening vascular injuries and embolism. In the last few decades many techniques and guidelines have been introduced to eliminate complications in creation of pneumoperitoneum. Classical closed technique (Verres needle) and the open classic technique (Hasson) are the most commonly used techniques for creation of pneumoperitoneum. To compare the rate of occurrence and nature of complications in open and closed laparoscopy during establishment of pneumoperitoneum in different surgical and gynaecological procedures. This was a comparative study conducted at three hospitals in Dibrugarh district, Assam, India from January 2012 to December 2014. Total 3000 cases were included in the study with 1500 cases of open laparoscopy and 1500 cases of closed laparoscopy. Complications occurring in both the groups were compared by using Fisher's-exact test. In closed laparoscopy group minor complications occurred in 80 (5.33%) and major complications in 20 (1.33%) cases. In open laparoscopy group minor complications were observed in 60 (4%) and major complications in 2 (0.13%). The p-value of the difference between the two groups for minor complications was 0.0834 and for major complications was 0.0001(significant). Open laparoscopy was seen to be better than closed laparoscopy in terms of not only the rate of occurrence of complications but also the nature and severity of the complications. This study is clinically relevant as there is no consensus for a particular method of safe entry in to the peritoneal cavity warranting the need for more research. Open technique can be performed in all cases irrespective of previous operative scar, suspected intra peritoneal adhesions or obesity. Favourable outcome may be achieved in closed technique in cases of normal BMI, absence of

    In medicine, the challenges faced by female faculty members who are attempting to achieve academic advancement have been well described. Various strategies have been proposed to increase academic productivity to aid the promotion of women in medicine. We propose an innovative collaboration strategy that encourages completion of an academic writing project. This strategy acknowledges the challenges inherent in achieving work–life balance and utilizes a collaborative work style with a group of peer physicians. The model is designed to encourage the completion and collation of independently prepared sections of an academic paper within a setting that emphasizes social networking and collaboration. This approach has many similarities to the construction of a quilt during a “quilting bee.” PMID:19172365

Universities are the institutions where all the opinions, various truth claims as well as social and political problems are discussed in a liberal and civilized way and the complicated problems are expressed clearly without any oppression and prevention. 2. Academic freedom includes first and foremost the right of freedom of research and thus freedom of using the essential knowledge methods, the right of possessing the necessary tools and conditions required for the research and the rights of scientific production, informing, learning and dissemination. 3. Academics possess the rights to benefit from the academic freedom without any limitation, to research and investigate according to their own preferences and interests, and to teach these without being exposed to any oppression and prevention. 4. This freedom of teaching that the academics have should not be used in a manner restricting students' freedom of learning; academics should avoid from being dogmatic in the research and education processes and respect students' rights of thinking differently and expressing themselves. 5. Academics accordingly should lead the students to evaluate and understand the new thoughts as a whole and to be tolerant to the thoughts they do not agree and to think in various ways. Also, academics should encourage the students to create their own opinions based on evidences and enable them to express these opinions freely and respect their freedom of expression. 6. Campuses should be safe environments where the students can express their own opinions freely. Suppressing the intellectual diversity and the plurality of viewpoints will decrease the productivity of teaching and learning process, restrict students' freedom of learning, and constrain the chance of formation of critical and in-depth thinking. 7. Critical thinking develops only in the campuses where various thoughts are expressed in a liberal way. Students should feel that they would not be prevented

    Full Text Available Hepatocellular carcinoma (HCC and intrahepatic cholangiocarcinoma (ICC are both regarded as primary liver cancers, having different biological behaviors and prognoses. Correct differentiation between them is essential for surgical planning and prognosis assessment. In 2005, the American Association for the Study of Liver Diseases (AASLD recommended that noninvasive diagnosis of HCC is achievable by a single dynamic technique (including contrast-enhanced ultrasound (CEUS showing intense arterial uptake followed by washout of contrast in the venous-delayed phases. However, CEUS has been dropped from the diagnostic techniques in the latest AASLD guideline according to the opinion of some authors from Europe that CEUS may offer false positive HCC diagnosis in patients with ICC. Since the update of AASLD guideline has been released, increased attention has been paid to this interesting topic. Remarkable controversy over this issue is present and this removal was not well received in Europe and Asia. This commentary summarized the opinions for the role of CUES in differentiation between HCC and ICC in recent years. It is concluded that prospective studies with strict design and large case series are mandatory to solve the controversies and stratification of ICC in terms of tumor size and liver background is also essential.

  6. Sjögren's syndrome. Controversies and progress.

    1997-09-01

    Diagnostic criteria for Sjögren's syndrome (SS) are required by both physicians and patients to (1) provide a rational basis for their symptoms, assess their prognosis, and guide therapy; (2) identify a group of patients who are most likely to share a common etiopathogenesis, in order to identify those genetic and environmental factors that are crucial in pathogenesis; (3) fill out the myriad medical insurance forms that require a diagnosis code; and (4) serve as a "shorthand" code that alerts specialists in different fields (oral medicine, ophthalmology, and a variety of specialists in internal medicine) to search for particular clinical problems found in the SS patient. The key question in this article is whether the term "Sjögren's syndrome" should apply to a rather restricted group of individuals (those with an autoimmune basis for exocrinopathy) or to a rather large group of individuals who share a similar symptom complex of dry eyes and mouth. Primary SS, as defined by San Diego criteria, is a systemic autoimmune disease that is characterized by keratoconjunctivitis sicca and xerostomia resulting from lymphocytic infiltrates of the lacrimal and salivary glands. The criteria for the diagnosis of SS continues to be controversial, leading to confusion in the clinical and research literature. It is important to distinguish SS (an idiopathic autoimmune process) from other processes including hepatitis C infection, retroviral infection, lymphoma, autonomic neuropathy, depression, primary fibromyalgia, and drug side effects that can result in sicca symptoms. Recent studies on pathogenesis of SS in human and animal models have examined the clonality of the T-cell infiltrates, the production of cytokines by lymphocytes and glandular epithelial cells, neuroendocrine and hormonal factors that affect glandular secretion, and the fine structure of antigens recognized by T cells and B cells. Studies in SS have allowed comparison of lymphocytes in blood and in the

  8. Experimental, controversial, and futuristic treatments for chronic tinnitus.

    Folmer, Robert L; Theodoroff, Sarah M; Martin, William Hal; Shi, Yongbing

    2014-01-01

    Because chronic tinnitus is a condition that negatively impacts the quality of life of millions of people worldwide, a safe and effective treatment for tinnitus has been sought for millennia. However, effective treatments for tinnitus are greatly outnumbered by ineffective strategies, medications, devices, and surgeries that continue to be developed and promoted for the condition. This article describes and critiques experimental, controversial, and potential treatments for chronic tinnitus. The purpose of this review is to provide information that should help patients and clinicians to select tinnitus treatment and management strategies most likely to be effective for each set of symptoms and circumstances. PubMed and MEDLINE databases (National Center for Biotechnology Information, U.S. National Library of Medicine) were searched for the term tinnitus in articles published from 1940 to 2012. Other historical documents and publications were also reviewed as needed for particular topics. Studies included in this review were selected to represent a sampling of treatment methodologies that have been used for tinnitus. Due to the heterogeneity of the studies reviewed, it was not appropriate to perform a meta-analysis. A selective review of the literature was conducted to summarize and critique published research results. Most invasive treatments for tinnitus should be avoided because (1) at best, there is scant evidence that any of these treatments is effective, and (2) the risk to patients for most invasive procedures is much greater than the risk posed by the tinnitus perception. Effective and noninvasive treatments for tinnitus include acoustic therapy (which includes hearing aids and other types of environmental sound enrichment); cognitive-behavioral therapy; psychological counseling; hypnosis; biofeedback; and relaxation training. Over-the-counter or prescription medications may be used as needed to facilitate sleep and to reduce anxiety, depression, or

  9. The heritage and museums field: A controversial cultural space

    Full Text Available The processes of acceptance as heritage and musealisation do not respond to history or aesthetics-related criteria, but rather to identity-related criteria. They do not concern scientists, specialists and policy-makers alone, but also social groups. The choice of cultural assets is not an objective consequence of their formal characteristics. It is the result of the selection made by social agents so as to represent a group identity. But no social group is homogeneous; on the contrary they are diverse and complex so the identity references, and therefore the cultural assets, do not have to be univocal. Beyond the aseptic discourses, many of these processes are controversial. Differences regarding the identity references and the uses to be made of cultural assets lead to the field of heritage and museums being spaces where interests and values clash. This article presents and analyses the conflicts that arose in the Basque municipality of Legazpi when the process of musealisation and acceptance of iron production as heritage first started.

    Los procesos de patrimonialización y musealización de la cultura no responden a criterios históricos o estéticos, sino identitarios. No atañen a científicos, especialistas y políticos solamente, sino a colectivos sociales. La elección de unos bienes culturales no es una consecuencia objetiva de sus características formales, es el resultado de la selección llevada a cabo por agentes sociales con el fin de representar una identidad grupal. Pero ningún colectivo social es uniforme, sino, al contrario, es diverso y complejo, de tal modo que los referentes identitarios y, consecuentemente, los bienes culturales no tienen por qué ser unívocos. Más allá de los discursos asépticos, muchos de esos procesos se presentan conflictivos. Diferencias acerca de los referentes identitarios y de los usos que se les quieren dar a los bienes culturales acarrean que el campo patrimonial y museístico sea un

  10. Whistleblowing in academic medicine.

    Rhodes, R; Strain, J J

    2004-02-01

    Although medical centres have established boards, special committees, and offices for the review and redress of breaches in ethical behaviour, these mechanisms repeatedly prove themselves ineffective in addressing research misconduct within the institutions of academic medicine. As the authors see it, institutional design: (1) systematically ignores serious ethical problems, (2) makes whistleblowers into institutional enemies and punishes them, and (3) thereby fails to provide an ethical environment. The authors present and discuss cases of academic medicine failing to address unethical behaviour in academic science and, thereby, illustrate the scope and seriousness of the problem. The Olivieri/Apotex affair is just another instance of academic medicine's dereliction in a case of scientific fraud and misconduct. Instead of vigorously supporting their faculty member in her efforts to honestly communicate her findings and to protect patients from the risks associated with the use of the study drug, the University of Toronto collaborated with the Apotex company's "stalling tactics," closed down Dr Olivieri's laboratory, harassed her, and ultimately dismissed her. The authors argue that the incentives for addressing problematic behaviour have to be revised in order to effect a change in the current pattern of response that occurs in academic medicine. An externally imposed realignment of incentives could convert the perception of the whistleblower, from their present caste as the enemy within, into a new position, as valued friend of the institution. The authors explain how such a correction could encourage appropriate reactions to scientific misconduct from academic medicine.

    2017-08-01

    Bibliometrics play an increasingly critical role in the assessment of faculty for promotion and merit increases. Bibliometrics is the statistical analysis of publications, aimed at evaluating their impact. The objective of this study is to describe h-index and citation benchmarks in academic psychiatry. Faculty lists were acquired from online resources for all academic departments of psychiatry listed as having residency training programs in Canada (as of June 2016). Potential authors were then searched on Web of Science (Thomson Reuters) for their corresponding h-index and total number of citations. The sample included 1683 faculty members in academic psychiatry departments. Restricted to those with a rank of assistant, associate, or full professor resulted in 1601 faculty members (assistant = 911, associate = 387, full = 303). h-index and total citations differed significantly by academic rank. Both were highest in the full professor rank, followed by associate, then assistant. The range in each, however, was large. This study provides the initial benchmarks for the h-index and total citations in academic psychiatry. Regardless of any controversies or criticisms of bibliometrics, they are increasingly influencing promotion, merit increases, and grant support. As such, benchmarking by specialties is needed in order to provide needed context.

    Full Text Available Abstract The researcher found the problem at MTSN 1 in the city of  Bengkulu at grade VIII I that students got difficulty in comprehending reading texts, and in understanding meanings of words in paragraphs, and teachers techniques  made the students bored. Therefore, the purpose of the research is to improve students’ reading comprehension through REAP techniques. The subject of the research is the students of  grade VIII I consisting of 27 students, 14 female students and 13 male students. The instruments of the research are reading tets, observation sheetteacher and the students, interview guide and that for documentary study.  The results of the research show that the  REAP teachniques are effective in improving the students’ reading comprehension. The students got involved directly and were able to cooperate with their peers during the teaching-learning process. The research was conducted in two cycles an the test was administered at the end of each cycle. From the average mean scores, it could be seen that there was improvement of the the students’ reading ability. In cycle I, the mean score was 70.5 and in cycle 2, it was 78.7,and at the Post assessment, it was  82.2. It means that the students’ mean scores has reached the research target. Thus, it can be concluded that REAPtechniques can improve the students’ readng comprehension.

    Full Text Available Synchronous major vessel resection during pancreaticoduodenectomy (PD for borderline resectable pancreatic adenocarcinoma remains controversial. In the 1970s, regional pancreatectomy advocated by Fortner was associated with unacceptably high morbidity and mortality rates, with no impact on long-term survival. With the establishment of a multidisciplinary approach, improvements in preoperative staging techniques, surgical expertise, and perioperative care reduced mortality rates and improved 5-year-survival rates are now achieved following resection in high-volume centres. Perioperative morbidity and mortality following PD with portal vein resection are comparable to standard PD, with reported 5-year-survival rates of up to 17%. Segmental resection and reconstruction of the common hepatic artery/proper hepatic artery (CHA/PHA can be performed to achieve an R0 resection in selected patients with limited involvement of the CHA/PHA at the origin of the gastroduodenal artery (GDA. PD with concomitant major vessel resection for borderline resectable tumours should be performed when a margin-negative resection is anticipated at high-volume centres with expertise in complex pancreatic surgery. Where an incomplete (R1 or R2 resection is likely neoadjuvant treatment with systemic chemotherapy followed by chemoradiation as part of a clinical trial should be offered to all patients.

    2004-05-01

    Full Text Available The planned research project described in this article focuses on the methods of trend research—not only in a narrow literal sense of techniques of data collection and data evaluation but also in a broader understanding of the logic of knowledge production in this controversial field. Initially trend research can be appointed between market research on the one hand and futurology on the other hand. Criticism regarding trend research as well as its innovative potential is also mentioned. Following the recent studies, trend research is conceived as application-oriented research in a broad sense. As far as the methodology is concerned, the proposed study promises to be an empirically-founded contribution by integrating analysis from sources such as explorative and focused conversations, observations and expert interviews. The study uses the example of trend research and asks the question how research is actually "done" and if it is application oriented or not. URN: urn:nbn:de:0114-fqs0402366

    2011-12-01

    One of the most controversial topics in the field of clinical psychology, online tele-health, or the integration of computers and the internet with therapeutic techniques, remains at the forefront of many debates. Despite potential interest, there are numerous factors that a psychologist must consider before integrating an online tele-health intervention into their own practice. This article outlines literature pertinent to the debate. The article begins with a brief history of the use of non-face-to-face interventions as well as the earliest recorded use of "tele-health" before discussing the modern benefits and risks associated with usage. Considerations for the psychologist as well as the client are detailed; incorporating ethical implications. The authors conclude that the utilization of tele-health interventions is an exponentially expanding field that should continue to be explored. Despite many well-conceived studies, a psychologist should educate themselves in all aspects of the new modes of intervention (e.g., ethical, legal, evidence-based treatments) before attempting to implement them into everyday practice. The article ends with a discussion on the acceptance among psychologists, as well as the outlook for the future. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Lean is a management system designed to enhance productivity by eliminating waste. Surgical practice offers many opportunities for improving efficiency. Our objective was to determine whether systematic implementation of lean thinking in an academic otolaryngology operating room improves efficiency and profitability and preserves team morale and educational opportunities. In an 18-month prospective quasi-experimental study, a multidisciplinary task force systematically implemented lean thinking within an otolaryngology operating room of an academic health system. Operating room turnover time and turnaround time were measured during a baseline period; an observer-effect period in which workers were made aware that their efficiency was being measured but before implementing lean changes; and an intervention period after redesign principles had been used. The impact on teamwork, morale, and surgical resident education were measured during the baseline and intervention periods through validated surveys. A profit model was applied to estimate the financial implications of the study. There was no difference between the baseline and observer-effect periods of the study for turnover time (p = 0.98) or turnaround time (p = 0.20). During the intervention period, the mean turnover time and turnaround time were significantly shorter than during the baseline period (29 vs 38 minutes; p lean thinking could create 6,500 hours of capacity annually. Application of lean management techniques to a single operating room and surgical service improved operating room efficiency and morale, sustained resident education, and can provide considerable financial gains when scaled to an entire academic surgical suite.

    Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy. A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Treatments for localized adiposities range from topical creams to liposuction. Most treatments lack a substantial proof of efficacy. The unpredictable treatment outcome can be related to the fact that cellulite adipose tissue is physiologically and biochemically different from subcutaneous tissue found elsewhere in the body. Part II of this two-part series on cellulite reviews the various treatment options that are currently available for human adipose tissue including, but not limited to, cellulite. It also focuses on newer techniques that can be potentially useful in the future for the treatment of cellulite. Copyright 2010 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    Miller, Brian K

    2013-10-01

    Members of Generation Y, or Millennials, have been accused of being lazy, whiny, pampered, and entitled, particularly in the college classroom. Using an equity theory framework, eight items from a measure of work entitlement were adapted to measure academic entitlement in a university setting in three independent samples. In Study 1 (n = 229), confirmatory factor analyses indicated good model fit to a unidimensional structure for the data. In Study 2 (n = 200), the questionnaire predicted unique variance in university satisfaction beyond two more general measures of dispositional entitlement. In Study 3 (n = 161), the measure predicted unique variance in perceptions of grade fairness beyond that which was predicted by another measure of academic entitlement. This analysis provides evidence of discriminant, convergent, incremental, concurrent criterion-related, and construct validity for the Academic Equity Preference Questionnaire.

    Singer, Peter

    1990-01-01

    The author describes the events surrounding his attempts to lecture on the subject of euthanasia in West Germany in June 1989. Singer, who defends the view that active euthanasia for some newborns with handicaps may be ethically permissible, had been invited to speak to professional and academic groups. Strong public protests against Singer and his topic led to the cancellation of some of his engagements, disruptions during others, and harrassment of the German academics who had invited him to speak. These incidents and the subject of euthanasia became matters of intense national debate in West Germany, but there was little public or academic support for Singer's right to be heard. Singer argues that bioethics and bioethicists must have the freedom to challenge conventional moral beliefs, and that the events in West Germany illustrate the grave danger to that freedom from religious and political intolerance.

    2015-05-01

    The inclusion of Positive Behavioral Intervention and Supports as a type of applied behavior analysis has often spurred considerable controversy. This controversy seems related to at least three areas of contention: measurement issues, views on aversive control, and the overall target of treatment. The present paper discusses these three areas in light of Horner and Sugai's target article and the current state of the field of applied behavior analysis. In the end, the authors are left wondering why this is even an ongoing controversy.

    Kingsbury, G Gage; McCall, Martha; Hauser, Carl

    2009-01-01

    Growth measurement and growth modeling have gained substantial interest in the last few years with the development of new statistical procedures and policy decisions such as the incorporation of growth into No Child Left Behind. The current study investigates the following four aspects of growth measurement: a) issues in the development of vertical scales to measure growth; b) design of instruments to measure academic growth; c) techniques for modeling individual student growth, and d) uses of growth information in a classroom. Measuring growth has always been a daunting task, but the development of measurement tools such as the Rasch model and computerized adaptive testing position us well to obtain high-quality data with which to measure and model the growth of an individual student across a course of study. This growth information, in norm-referenced and standards-referenced form, should enhance educators' ability to enrich student learning.

    This lecture presents the experimental techniques, developed in the last 10 or 15 years, in order to perform a new class of experiments with exotic nuclei, where the reactions induced by these nuclei allow to get information on their structure. A brief review of the secondary beams production methods will be given, with some examples of facilities in operation or under project. The important developments performed recently on cryogenic targets will be presented. The different detection systems will be reviewed, both the beam detectors before the targets, and the many kind of detectors necessary to detect all outgoing particles after the reaction: magnetic spectrometer for the heavy fragment, detection systems for the target recoil nucleus, {gamma} detectors. Finally, several typical examples of experiments will be detailed, in order to illustrate the use of each detector either alone, or in coincidence with others. (author)

  17. Pancreatic islet regeneration: Therapeutic potential, unknowns and controversy

    Directory of Open Access Journals (Sweden)

    Ingrid L. Cockburn

    2015-07-01

    Full Text Available Glucose homeostasis in mammals is primarily maintained by the insulin-secreting β-cells contained within pancreas-resident islets of Langerhans. Gross disruption of this glucose regulation as a result of pancreatic dysfunction frequently results in diabetes, which is currently a major health concern in South Africa, as well as globally. For many years, researchers have realised that the pancreas, and specifically the islets of Langerhans, have a regenerative capacity, as islet mass has frequently been shown to increase following induced pancreatic injury. Given that gross β-cell loss contributes significantly to the pathogenesis of both type 1 and type 2 diabetes, endogenous pancreatic islet regeneration has been investigated extensively as a potential β-cell replacement therapy for diabetes. From the extensive research conducted on pancreatic regeneration, opposing findings and opinions have arisen as to how, and more recently even if, pancreatic regeneration occurs following induced injury. In this review, we outline and discuss the three primary mechanisms by which pancreatic regeneration is proposed to occur: neogenesis, β-cell replication and transdifferentiation. We further explain some of the advanced techniques used in pancreatic regeneration research, and conclude that despite the technologically advanced research tools available to researchers today, the mechanisms governing pancreatic regeneration may remain elusive until more powerful techniques are developed to allow for real-time, live-cell assessment of morphology and gene expression within the pancreas.

    Mokhtarzadeh, Ali; Harrison, Andrew R

    2015-01-01

    The management issues associated with pediatric ptosis begin with determining the etiology of the ptosis, and considering how the eyelid position affects the child’s visual and psychosocial development. These ultimately determine if and when surgical management should be undertaken. Surgical challenges include the lack of intraoperative feedback regarding the dynamic eyelid height and contour under general anesthesia. When the eyelid elevators do not function or if there is little drive to lift the involved eyelid, obtaining good surgical outcomes can be extremely challenging. A plethora of surgical techniques and materials have been developed, each with their own benefits and drawbacks. Careful preoperative evaluation, planning and counseling can usually result in satisfactory surgical results with happy parents and patients. Families should always be aware that the child will need to be followed long term for visual development, ocular health, and they need to be counseled regarding the possibility of revision surgery.

  3. Staging scientific controversies: a gallery test on science museums' interactivity.

    2009-01-01

    The "transfer" model in science communication has been addressed critically from different perspectives, while the advantages of the interactive model have been continuously praised. Yet, little is done to account for the specific role of the interactive model in communicating "unfinished science." The traditional interactive methods in museums are not sufficient to keep pace with rapid scientific developments. Interactive exchanges between laypeople and experts are thought mainly through the lens of a dialogue that is facilitated and framed by the traditional "conference room" architecture. Drawing on the results of a small-scale experiment in a gallery space, we argue for the need for a new "architecture of interaction" in museum settings based on art installation and simulation techniques, which will enhance the communication potentials of science museums and will provide conditions for a fruitful even-handed exchange of expert and lay knowledge.

    Productive procrastination replaces one adaptive behavior with another adaptive—albeit less important—behavior (e.g., organizing notes instead of studying for an exam). We identified adaptive and maladaptive procrastination styles associated with academic and alcohol outcomes in 1106 college undergraduates. Cluster analysis identified five academic procrastination styles—non-procrastinators, academic productive procrastinators, non-academic productive procrastinators, non-academic procrastinators, and classic procrastinators. Procrastination style differentially predicted alcohol-related problems, cravings, risk of alcohol use disorders, and GPA (all ps procrastination and academic productive procrastination were most adaptive overall; non-academic productive procrastination, non-academic procrastination, and classic procrastination were least adaptive. Productive procrastination differed from other procrastination strategies, and maladaptive procrastination styles may be a useful risk indicator for preventative and intervention efforts.

    Zacks, Shlomo; Hen, Meirav

    2018-01-01

    Procrastination is a widespread phenomenon in academic settings. It has been studied from many different theoretical angles, and a variety of causes and consequences have been suggested. Recent studies support the notion that academic procrastination can be seen from a situational perspective and as a failure in learning self-regulation. It suggests that interventions should address situational as well as deficits in self-regulation to help students overcome their procrastinating tendencies. The present review examined the recent literature on causes and consequences of academic procrastination and the limited number of studies of academic interventions for academic procrastination. Findings of this review strengthen the need to further study the topic of academic interventions for academic procrastination and to develop effective interventions. At the end of this review, several suggestions for the development of academic interventions are outlined.

    Norplant® is the brand name of the world's first registered subdermal hormonal contraceptive implant, developed by the laboratories of the Population Council, an international organisation working in the area of fertility and population growth. The article revisits the trajectory of this contraceptive in Brazil from its arrival through clinical trials to its eventual ban in 1986 by the Brazilian regulatory agency responsible for approving medications at the time. Its circulation generated controversies related to research practices, side effects and political uses of the drug as a birth control method. This article focuses its analysis on the divergences related to research practices. It uses a controversy analysis technique, reviewing the versions of those involved, investigating their understandings and the effects that this object generated in their networks. Norplant® provoked displacements and associations between civil society groups, State authorities, scientists and physicians, industry, pharmaceutical products, research procedures, bureaucratic instruments, and the female users of the contraceptives. Scientific styles of medical thought were shaken up and new forms of thinking about scientific autonomy began to be discussed in the country.

    2013-04-01

    Vaccination is one of the most important public health interventions in the reduction childhood morbidity and mortality. Thimerosal is an organic mercury compound used as preservante in multi-dose vials. Often in Peru, there are waves of controversy about the safety of this type of vaccines, mainly arguing that there is an association between them and autism. As a result of these controversies, there have been some voices asking for laws banning thimerosal-containing vaccines, which would have a large impact in costs and the logistic aspects of the public vaccination programs. The aim of this article is to review the literature for the main controversies about thimerosal in vaccines and its supposed association to autism. We made an historical review about these controversies given the available scientific evidence and the statements from important international organizations. We concluded that the current available evidence do not support an association between thimerosal and childhood neurodevelopmental disorders, such as autism.

  12. Is healthcare providers' value-neutrality depending on how controversial a medical intervention is? Analysis of 10 more or less controversial interventions.

    Science.gov (United States)

    Lynöe, Niels; Björk, Joar; Juth, Niklas

    2017-09-01

    Swedish healthcare providers are supposed to be value-neutral when making clinical decisions. Recent conducted studies among Swedish physicians have indicated that the proportion of those whose personal values influence decision-making (the value-influenced) vary depending on the framing and the nature of the issue. To examine whether the proportions of value-influenced and value-neutral participants vary depending on the extent to which the intervention is considered controversial. To discriminate between value-neutral and value-influenced healthcare providers, we have used the same methods in six vignette based studies including 10 more or less controversial interventions. To be controversial was understood as being an intervention where conscientious objections in healthcare have been proposed or an intervention that is against law and regulations. End of life decisions and female reproduction issues are associated with conscientious objection and more or less against regulations, and also resulted in the highest proportions of value-influenced participants. Following routines, which is not in conflict with official values, were associated with one of the lowest proportion of value-influenced participants. The difference between the highest and lowest proportions of value-influenced participants among the 10 examined interventions was significant (81.8% (95% confidence interval: 78.1-85.5) versus 34.7% (95% confidence interval: 29.2-40.2)). The study indicates that the proportions of value-neutral participants decrease the more controversial an issue is, and vice versa. In some cases, however, framing effects may potentiate or obscure this association. As a bold hypothesis, we suggest the proportion of value-neutral or value-influenced might indicate how controversial an issue is.

  13. Projecting an academic identity in some reflective genres

    Directory of Open Access Journals (Sweden)

    Ken Hyland

    2011-04-01

    Full Text Available Research on academic writing has long stressed the connection between writing and the creation of an author’s identity (Ivanič, 1998; Hyland, 2010. Identity is said to be created from the texts we engage in and the linguistic choices we make, thus relocating it from hidden processes of cognition to its social construction in discourse. Issues of agency and conformity, stability and change, remain controversial, however. Some writers question whether there is an unchanging self lurking behind such discourse and suggest that identity is a “performance” (see for instance Butler, 1990 while others see identity as the product of dominant discourses tied to institutional practices (Foucault, 1972. All this has been of particular interest to teachers and researchers of EAP because students and academics alike often feel uncomfortably positioned, even alienated, by the conventions of academic discourse. They sometimes complain that the voice they are forced to use requires them to “talk like a book” by adopting a formal and coldly analytical persona.In this paper I want to explore how we construct an identity in three rather neglected academic genres where the requirements of anonymity and impersonality are more relaxed. In thesis acknowledgements, doctoral prize applications and bio statements, writers are exempted from formal conventions of disciplinary argument and have an opportunity to reveal something of how they want to be seen by others. My question is: What use do they make of with these opportunities?

    2015-07-01

    Full Text Available This paper presents an empirical (historical survey about the insertion, definition and valuation of scientific controversies in psychology on the basis of certain historiographical trends in History of Psychology. With the overall objective of reviewing the importance of controversial instances for the scientific development of psychology, and the specific objective of enabling rapprochement between the historiography of psychology and social studies of science, the definition and explanation given about historical controversies by the classic historiography of psychology are first described, emphasizing the anomalous character of such controversies to said historiography given the implicit theoretical and methodological principles of such tradition. The redefinition of historical controversies by the ‘new history’ of psychology developed since 1970 is then detailed. It is noted that such redefinition took place partly due to the historians’ incorporation of certain sociological and socio-historical principles and explanatory resources from social history of science and social studies of science. The positive character of such a redefinition and of the foresight of deeper socio-historical analysis of controversies in psychology is then concluded.

  15. Turkish Social Studies Teachers’ Thoughts About the Teaching of Controversial Issues

    Full Text Available In today’s world, one of the primary goals of education is to raise individuals as citizens equipped with the skills of communication, high-level thinking, problem solving and questioning as well as with a global viewpoint. Introducing controversial issues into the classroom environment may be among the steps to be taken to achieve these goals. In this context, this study has the primary goal of revealing Social Studies teachers’ thoughts about the teaching of controversial issues in the classroom environment. This study adopted mixed methods. The study participants consisted of Social Studies teachers working in Bursa, which is a large-scale province of Turkey, in the 2014-2015 school year. According to the study findings, while terror was the most controversial issue, faith in creation was the least controversial issue. In addition, teachers mainly preferred to introduce issues related to the Social Studies curriculum and that were appropriate for the students’ preparedness. However, another result is that controversial issues contributed to students’ acquisition of personal critical skills such as high-level thinking and communication. It was also observed that the teaching of controversial issues was related to the Social Studies lesson and was important for the achievement of the goals of the lesson.

  16. Atherosclerosis Induced by Chlamydophila pneumoniae: A Controversial Theory

    Directory of Open Access Journals (Sweden)

    Hamidreza Honarmand

    2013-01-01

    Full Text Available More than a century ago, inflammation and infection were considered to have atherogenic effects. The old idea that coronary heart disease (CHD possibly has an infectious etiology has only reemerged in recent years. Atherosclerosis is the main pathological process involved in CHD and is, logically, the first place to look for infectious etiology. The process of atherosclerosis itself provides the first hints of potential infectious cause. Smooth muscle proliferation, with subsequent intimal thickening, luminal narrowing, and endothelial degeneration, constitutes the natural history of atherosclerosis, being with the severity and speed of these changes. Both viral and bacterial pathogens have been proposed to be associated with the inflammatory changes found in atherosclerosis. Recently, Chlamydophila pneumoniae (C. pneumoniae has been implicated as a possible etiologic agent of coronary artery disease and atherosclerosis. New evidence which supports a role for C. pneumoniae in the pathogenesis of atherosclerosis has emerged. C. pneumoniae has been detected in atherosclerotic arteries by several techniques, and the organism has been isolated from both coronary and carotid atheromas. Recent animal models have suggested that C. pneumoniae is capable of inducing atherosclerosis in both rabbit and mouse models of atherosclerosis. Furthermore, human clinical treatment studies which examined the use of antichlamydial macrolide antibiotics in patients with coronary atherosclerosis have been carried out. The causal relationship has not yet been proven, but ongoing large intervention trials and research on pathogenetic mechanisms may lead to the use of antimicrobial agents in the treatment of CHD in the future.

  17. CONTROVERSIES ON THE APPLICATION OF THE VAT SPLIT PAYMENT MECHANISM

    Directory of Open Access Journals (Sweden)

    PALIU – POPA LUCIA

    2017-11-01

    Full Text Available Taking into account the urgent need to attract additional amounts to the state budget to cover the increased budget expenditures involved in the implementation of the government program, by the end of August 2017, the Government of Romania adopted an ordinance obliging the entities to apply, starting on January 1st 2018, the VAT split payment mechanism, system which no longer allows them to use the value added tax cashed affently to the delivery of goods and provision of services, which is why these amounts are to be cashed in separate accounts opened by entities in the state treasury or credit institutions. Only that, later, through the draft of Law on the approval of that ordinance, the Senate made changes to the legislative act, so that the VAT split payment would only apply to companies in insolvency or that register delays in payment of the tax. Although this measure aims at combating the tax evasion and fraud by increasing the voluntary compliance and tax collection degree, the measure can prove to be unfounded, which violates the legislative technique and, in particular, the Community provisions by being inappropriate. In this context, the main objective of this scientific approach is to identify the special situations that arise at the level of entities as a result of the application of the breakdown mechanism of value added tax and to determine the possible advantages and disadvantages.

    Full Text Available This case study investigated the impact of academic capitalism on academic culture by examining the perspectives of faculty members in an American academic department with significant industrial funding. The results of this study indicate that faculty members believe that the broad integrity of the academic culture remains unaffected in this department and they consider industrial sponsorship as a highly effective vehicle for enhancing the quality of education of students and pursuing their scientific interests. This study provides valuable insights to federal and institutional policiescreated to foster industry-academia partnerships and commercialization of academic research.

    Full Text Available Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient′s dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.
