    The ability of a physician to select individuals likely to benefit from patch testing depends on his or her ability to interpret responses to enquiries related to contact allergy. The significance of such responses to questions of nickel, fragrance and colophon allergy is unclear. The specificity, sensitivity and predictive value of questions relating to nickel, fragrance and colophony allergy were determined. A total of 258 patients attending for routine patch testing were questioned about skin reactions to nickel, fragrances and Elastoplast (Smith and Nephew Healthcare, Hull, England). All subjects were then patch tested to nickel, fragrance mix, and colophony. Responses to questions were compared with patch test results. The sensitivity of questions relating to nickel, fragrance, and colophony was 82%, 49%, and 71%, respectively. The specificity of the same questions was 77%, 79%, and 90%; the positive predictive value was 54%, 46% and 29%, respectively. After adjustment to include clinical relevance, the sensitivity of nickel questions rose to 100%. These data permit greater understanding of the role of patient history in selection of patients for patch testing. Copyright 2000 by W.B. Saunders Company

  2. On safety goals and related questions

    International Nuclear Information System (INIS)

    Kaplan, S.

    1985-01-01

    The question of what safety goals should be established for nuclear power plants has been receiving a great deal of urgent attention and debate recently, both by those responsible for reactor licensing and by others interested in establishing a quantitative measure of reactor safety. The same question, phrased alternately in the forms: ''What is acceptable risk?'' and ''How safe is safe enough?,'' has been debated extensively for quite a long time. The purpose of the present paper, therefore, is to show that the above questions, taken at face value, exist within an unworkable context, which the authors shall call the Old Regulatory Context (ORC), and that within this context lead to several absurdities. They shall argue that this context needs to be replaced by another context, which they call the Decision Theory Context (DTC), and which the authors discuss here

  3. Special relativity as an open question

    International Nuclear Information System (INIS)

    Albert, D.Z.

    2000-01-01

    There seems to me to be a way of reading some of the trouble we have lately been having with the quantum-mechanical measurement problem (not the standard way, mind you, and certainly not the only way; but a way that nonetheless be worth exploring) that suggests that there are fairly prosaic physical circumstances under which it might not be entirely beside the point to look around for observable violations of the special theory of relativity. The suggestion I have in mind is connected with attempts over the past several years to write down a relativistic field-theoretic version of the dynamical reduction theory of Ghirardi, Rimini, and Weber [Physical Review D34, 470-491 (1986)], or rather it is connected with the persistent failure of those attempts, it is connected with the most obvious strategy for giving those attempts up. And that (in the end) is what this paper is going to be about. (orig.)

    2016-01-01

    The term physical literacy is relatively new, and its definition, conceptual underpinning, how it is measured, how to change it, and its relationship with holistic health and wellness across the life span are a few of many foundational issues that lack consensus. At present, there are more questions than answers. The purpose of this article is to highlight 10 important research questions related to physical literacy with the hope of fueling future research activity and debate. Input was sought from international experts and practitioners on priorities and research gaps related to physical literacy. This list was supplemented by personal experience and research priorities identified in published manuscripts. From these various sources, the top 10 research questions related to physical literacy were compiled. Research related to physical literacy is in its infancy, and many important, even fundamental research questions and priorities remain unanswered. Research needs are summarized within 4 themes: monitoring physical literacy, understanding the physical literacy journey, enhancing physical literacy, and the benefits of physical literacy. Specific research questions relate to identifying measurable aspects of physical literacy and how they change across cultures and throughout the life span, as well as understanding the individual and environmental factors that describe the physical literacy journey and are effective targets for interventions. Physical literacy is increasingly recognized as the foundation for a healthy active lifestyle; however, robust research demonstrating its constitution, its relationship with health-related outcomes, and intervention strategies for its improvement remains to be completed.

    This paper describes the methodological developments of the sexual health items included in the Health Behaviour in School-aged Children (HBSC) study since their mandatory inclusion in the study in 2002. The current methodological, ethical and pedagogical challenges in measuring young people's sexual health behaviours are discussed along with the issues associated with the sexual health items introduced to the HBSC study in 2002. The development and piloting of new cross-national items for use in the 2013/14 HBSC data collection are presented and discussed. An international pilot study was undertaken to determine the impact of these proposed changes. Questionnaires and classroom discussion groups were conducted in five pilot countries in 2012/2013 (France, Hungary, Ireland, Portugal and Romania) with a total of 612 school-aged children (age M = 15.55 years, SD = 0.95). The majority of participants in each country provided positive feedback about the appropriateness of the questions. Some small cross-national differences were found in the self-reported quantitative data relating to the appropriateness of the questions (χ 2  = 22.831, df = 9, p = .007, V = .117). Qualitative feedback suggests that for the vast majority of students the phrasing and age-targeting of the questions were considered appropriate. With the exception of a small number of respondents who commented on the clarity and/or personal nature of the content, no specific issues with the questions were identified. These findings provide guidance on the answerability (including the extent of missing and inconsistent data), understandability, acceptability (including in different cultures) and relevance of questions to potential participants. The findings from the pilot study suggest that in general, the questions are understandable, acceptable, and of a high priority to the target population, and that the simplification has significantly reduced the proportion of missing data

    Edelen, Dominic G B

    1970-01-01

    Theoretical researches in general relativity and observational data from galactic astronomy combine in this volume in contributions to one of the oldest questions of natural philosophy: Is the structure of the physical world more adequately described by a continuous or a discrete mode of representation? Since the days of the Pythagoreans, this question has surfaced from time to time in various guises in science as well as in philosophy. One of the most bitterly contested and illuminating controversies between the continuous and the discrete viewpoints is to be found in the wave versus corpuscular description of optical phenom­ enae. This controversy was not resolved to the satisfaction of most of its protaganists until the development of the quantum theory. However, several obscurities that still becloud the question suggest that some deeper formulation may be necessary before more satisfactory answers can be given 1. The firm establishment of the validity of quantized structure and discrete energy distribut...

    Full Text Available The study aimed at analyzing English questions of the Jordanian Secondary Certificate Examinations via Blooms' cognitive levels. An analysis sheet was prepared by the researcher for the purpose of the study, which was ensured to be valid and reliable. The whole questions of the general secondary examinations for English course in both levels (level three and level four during 2010-2013 composed the sample of the study. Frequencies and percentages were tabulated to facilitate the analysis of the results. The result of the study revealed that the total percentage of the first three levels (comprehension, knowledge, and analysis is (69.6 but the total percentage of the last three levels (application, synthesis, and evaluation is (30.4 so it indicated that the English questions included in general secondary examinations emphasize low order thinking levels. The researcher recommended that the questions designers should improve their questioning techniques in writing questions of exams.

    In this article, we elaborate on 10 current research questions related to the "teaching games for understanding" (TGfU) approach with the objective of both developing the model itself and fostering game understanding, tactical decision making, and game-playing ability in invasion and net/wall games: (1) How can existing scientific approaches from different disciplines be used to enhance game play for beginners and proficient players? (2) How can state-of-the-art technology be integrated to game-play evaluations of beginners and proficient players by employing corresponding assessments? (4) How can complexity thinking be utilized to shape day-to-day physical education (PE) and coaching practices? (5) How can game making/designing be helpfully utilized for emergent learning? (6) How could purposeful game design create constraints that enable tactical understanding and skill development through adaptive learning and distributed cognition? (7) How can teacher/coach development programs benefit from game-centered approaches? (8) How can TGfU-related approaches be implemented in teacher or coach education with the goal of facilitating preservice and in-service teachers/coaches' learning to teach and thereby foster their professional development from novices to experienced practitioners? (9) Can the TGfU approach be considered a helpful model across different cultures? (10) Can physical/psychomotor, cognitive, affective/social, and cultural development be fostered via TGfU approaches? The answers to these questions are critical not only for the advancement of teaching and coaching in PE and sport-based clubs, but also for an in-depth discussion on new scientific avenues and technological tools.

  16. PHYSICAL GEOGRAPHY: CONSTRUCTS AND QUESTIONS RELATING TO CURRICULUM AND PEDAGOGY

    Directory of Open Access Journals (Sweden)

    Duncan Hawley

    Full Text Available ABSTRACT:A series of questions are raised to prompt examination of the role and place of physical geography in the school curriculum and its relationship with science; consequently challenging teachers to consider the implications for their pedagogy. An examination of physical geography knowledge illustrates how it is constructed with a plurality of meanings, and a framework for interpreting different meanings and approaches is offered followed by critical discussion of the dominant discourses and teaching approaches adopted in schools. Contexts have played an important role in influencing how physical geography has been taught in schools and the paper discusses the merits of recent trends towards teaching physical geography via issues- based or social contexts, where physical topics are explored for social relevance rather than understanding of the physical processes and drivers. Evidence for and against this approach is outlined and questions raised about whether integrated and applied approaches to teaching physical geography dilute the quality and emphasis of learning and understanding. It is suggested that physical geography, as taught in schools, may need to catch up by adopting a less ‘fixist’ view of the physical world, by which teachers develop a curriculum and pedagogies more appropriately matched to contemporary understandings of physical geography, so enabling students to develop as more informed, critical thinkers when considering the physical world. KEY WORDS:Physical geography, schools, curriculum, pedagogy, knowledge, questions, debate. RÉSUMÉ:Une série de questions sont soulevées pour inciter examen du rôle et la place de la géographie physique dans les programmes scolaires et de sa relation avec la science ; offrant donc un défi pour les enseignants d’examiner les implications de leur enseignement.

  17. Top 10 Research Questions Related to Youth Aerobic Fitness.

    Armstrong, Neil

    2017-06-01

    Peak oxygen uptake ([Formula: see text] 2 ) is internationally recognized as the criterion measure of youth aerobic fitness, but despite pediatric data being available for almost 80 years, its measurement and interpretation in relation to growth, maturation, and health remain controversial. The trainability of youth aerobic fitness continues to be hotly debated, and causal mechanisms of training-induced changes and their modulation by chronological age, biological maturation, and sex are still to be resolved. The daily physical activity of youth is characterized by intermittent bouts and rapid changes in intensity, but physical activity of the intensity and duration required to determine peak [Formula: see text] 2 is rarely (if ever) experienced by most youth. In this context, it may therefore be the transient kinetics of pulmonary [Formula: see text] 2 that best reflect youth aerobic fitness. There are remarkably few rigorous studies of youth pulmonary [Formula: see text] 2 kinetics at the onset of exercise in different intensity domains, and the influence of chronological age, biological maturation, and sex during step changes in exercise intensity are not confidently documented. Understanding the trainability of the parameters of youth pulmonary [Formula: see text] 2 kinetics is primarily based on a few comparative studies of athletes and nonathletes. The underlying mechanisms of changes due to training require further exploration. The aims of the present article are therefore to provide a brief overview of aerobic fitness during growth and maturation, increase awareness of current controversies in its assessment and interpretation, identify gaps in knowledge, raise 10 relevant research questions, and indicate potential areas for future research.

  19. A few questions related to information and symmetries in physics

    Science.gov (United States)

    Darvas, G.

    2017-01-01

    Information exchange between inanimate objects (like individual physical particles, or systems) involves special approaches, due to the peculiarity that conscious information emitters/recipients are excluded from the process. This paper aims at answering a part of some questions arising by such approaches. One can ask the question, whether is it possible to speak about physical information when there is no live recipient to accept, evaluate, and use it? Can one speak about "physical information" (e.g., signal exchange) between inanimate physical objects at all? (cf., Feynman diagrams.) If yes, what is the nature of that information? Is (physical) information a passive phenomenon, or its existence presumes activity? What does a signal represent if it is not observed and used at the other end, and where is that other end when one can say that the signal in question was lost without observation or use? I try to illustrate my personal answers with a few examples quoted from the history of 20th c. physics. My answers to the questions are not intended to be revelations and to provide final solutions, rather they serve as arguments and indicate that nothing is closed, the discussion is open.

  20. Theorising international monetary relations: three questions about the significance of materiality

    Directory of Open Access Journals (Sweden)

    Anna Leander

    2015-12-01

    Full Text Available Abstract This article engages a conversation with Benjamin Cohen by raising three questions about the significance of materiality. The paper's questions focus on how materiality can be included in theorizations so that its political import is not defined away from the outset. The article does this focussing on Cohen's treatment of electronic money and its significance for the Politics of International Monetary Relations. The first question posed is about ontology, the second about agency and the third about the scope of politics. The three questions are raised as a conversation in which arguments and counterarguments are advanced. The questions are therefore posed with Cohen's contributions to theorizing the political significance of materiality as their point of departure. They are formulated as a consequence of bringing these contributions in relation to insights from the Social Studies of Finance. From this perspective it would seem that a more far reaching engagement with materiality (in terms of ontology, agency and epistemology is necessary to capture its political significance for international monetary politics and currency hierarchies. The article does not conclude in conventional fashion but purposefully strives to leave these questions open for discussion.

  1. Top 10 research questions related to children physical activity motivation.

    Science.gov (United States)

    Chen, Ang

    2013-12-01

    Physical activity is critical to healthy development of children. It is well documented that helping children develop and sustain a physically active lifestyle requires children to become motivated. Many studies have been conducted in the past 2.5 decades on determinants and correlates for children and adolescents' physical activity motivation. The findings have informed researchers and practitioners about motivation sources for children and effective strategies to motivate children in given physical activity settings. Built on the extensive knowledge base and theoretical platforms formed by these research studies, the purpose of this article is to take a look at the current research landscape and provide subjective thoughts about what we still need to know about children's physical activity motivation. The product of this subjective thinking process rendered 10 potential questions for future research on children's physical activity motivation in both in-school and out-of-school settings. These topics encompass those focusing on children's physical activity motivation as a mental dispositional process, those conceptualizing the motivation as an outcome of person-environment interactions, and those attempting to dissect the motivation as an outcome of social-cultural influences and educational policies. It is hoped that the topics can serve researchers interested in children's physical activity motivation as starting blocks from which they can extend their conceptual thinking and identify research questions that are personally meaningful. It is also hoped that the list of potential questions can be helpful to researchers in accomplishing the imperative and significant mission to motivate children to be physically active in the 21st century and beyond.

  2. General Relativity and Cosmology: Unsolved Questions and Future Directions

    Directory of Open Access Journals (Sweden)

    Ivan Debono

    2016-09-01

    Full Text Available For the last 100 years, General Relativity (GR has taken over the gravitational theory mantle held by Newtonian Gravity for the previous 200 years. This article reviews the status of GR in terms of its self-consistency, completeness, and the evidence provided by observations, which have allowed GR to remain the champion of gravitational theories against several other classes of competing theories. We pay particular attention to the role of GR and gravity in cosmology, one of the areas in which one gravity dominates and new phenomena and effects challenge the orthodoxy. We also review other areas where there are likely conflicts pointing to the need to replace or revise GR to represent correctly observations and consistent theoretical framework. Observations have long been key both to the theoretical liveliness and viability of GR. We conclude with a discussion of the likely developments over the next 100 years.

  3. Outstanding Questions In First Amendment Law Related To Food Labeling Disclosure Requirements For Health.

    Science.gov (United States)

    Pomeranz, Jennifer L

    2015-11-01

    The federal and state governments are increasingly focusing on food labeling as a method to support good health. Many such laws are opposed by the food industry and may be challenged in court, raising the question of what is legally feasible. This article analyzes outstanding questions in First Amendment law related to commercial disclosure requirements and conducts legal analysis and policy evaluation for three current policies. These include the Food and Drug Administration's draft regulation requiring an added sugar disclosure on the Nutrition Facts panel, California's proposed sugar-sweetened beverage safety warning label bill, and Vermont's law requiring labels of genetically engineered food to disclose this information. I recommend several methods for policy makers to enact food labeling laws within First Amendment parameters, including imposing factual commercial disclosure requirements, disclosing the government entity issuing a warning, collecting evidence, and identifying legitimate governmental interests.

  13. Simple neck pain questions used in surveys, evaluated in relation to health outcomes: a cohort study

    Science.gov (United States)

    2012-01-01

    Background The high prevalence of pain reported in many epidemiological studies, and the degree to which this prevalence reflects severe pain is under discussion in the literature. The aim of the present study was to evaluate use of the simple neck pain questions commonly included in large epidemiological survey studies with respect to aspects of health. We investigated if and how an increase in number of days with pain is associated with reduction in health outcomes. Methods A cohort of university students (baseline age 19–25 years) were recruited in 2002 and followed annually for 4 years. The baseline response rate was 69% which resulted in 1200 respondents (627 women, 573 men). Participants were asked about present and past pain and perceptions of their general health, sleep disturbance, stress and energy levels, and general performance. The data were analyzed using a mixed model for repeated measurements and a random intercept logistic model. Results When reporting present pain, participants also reported lower prevalence of very good health, higher stress and sleep disturbance scores and lower energy score. Among those with current neck pain, additional questions characterizing the pain such as duration (categorized), additional pain sites and decreased general performance were associated with lower probability of very good health and higher amounts of sleep disturbance. Knowing about the presence or not of pain explains more of the variation in health between individuals, than within individuals. Conclusion This study of young university students has demonstrated that simple neck pain survey questions capture features of pain that affect aspects of health such as perceived general health, sleep disturbance, mood in terms of stress and energy. Simple pain questions are more useful for group descriptions than for describing or following pain in an individual. PMID:23102060

    Full Text Available Abstract Background The high prevalence of pain reported in many epidemiological studies, and the degree to which this prevalence reflects severe pain is under discussion in the literature. The aim of the present study was to evaluate use of the simple neck pain questions commonly included in large epidemiological survey studies with respect to aspects of health. We investigated if and how an increase in number of days with pain is associated with reduction in health outcomes.

  15. Necessary and impossible: on spiritual questions in relation to early induced abortion

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available No matter how technically developed and medically sophisticated our society becomes, in the end we are all going to die. In other words, as human beings we are, from time to time, forced to deal with situations of existential significance. Existential and spiritual questions remain relevant—even in a country where most people­ have abandoned institutional forms of religion. But how do people­ deal with these questions? Sweden continues to uphold an extreme position, from a global perspective, when it comes to religiosity and traditional values. No other country in the world has, to such a great extent, left traditional and survival values on the behalf of those based on rationality and self expression. Religious and ethnic minorities have brought new forms of piety to the Swedish scene, but secularization and religious privatization dominate. In this situation, it is important to study people’s ways of dealing with existential life situations. What do people think, feel, believe and do in the presence of the ultimate questions—when there exists no common ground for meaning-making? This article begins with an outline of the state of religion in Sweden, against the backdrop of the contemporary climate in Western culture. This is followed by an introduction to abortion in Sweden, and to abortion research of interest for this paper. Ritual participation is the next topic, leading to concepts of importance for the pilot study: existential homelessness and individualized rituals. In the rest of the article the focus is on the pilot study and a discussion of its results in relation to the existential situation in Sweden at large.

  16. Subject-Object Asymmetry in the Second Language Acquisition of English Relatives and Embedded Wh-Questions.

    2016-12-01

    This study examined subject-object asymmetry and developmental sequence in the second language (L2) acquisition of three types of wh-extraction, i.e., English headed relatives, headless relatives, and embedded wh-questions. Sixty-four L1 Korean learners of English completed an elicited imitation task and a grammaticality judgment task. The learners demonstrated a subject advantage in the headed RCs and headless RCs, but an object advantage in the embedded wh-questions, which suggests that they treat embedded wh-questions differently from headed relatives and headless relatives despite the similarities in surface forms. The learners further demonstrated the order of developing headless RCs followed by embedded wh-questions, and subsequently headed RCs, which supports the primacy of headless relatives as a simple nominal in L2 development.

    To determine the diagnostic accuracy of three screening questions (3Q/TMD) in relation to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), in a specialized clinic. Consecutive patients, >18 years, referred with a possible TMD complaint to the Orofacial Pain and Dysfunction clinic, Academic Centre for Dentistry Amsterdam, the Netherlands, were included in the study. All patients (n = 449; mean age 44 years; 72% females), answered the 3Q/TMD and the DC/TMD questionnaire before a DC/TMD examination. The 3Q/TMD constitutes of two questions on weekly pain from the jaw, face and temple region (Q1), and on function (Q2), and one function-related question on weekly catching and/or locking of the jaw (Q3). Q1 and Q2 were evaluated in relation to a DC/TMD pain diagnosis and Q3 in relation to a subgroup of DC/TMD intra-articular diagnosis, referred to as the reference standard. In total, 44% of patients received a pain-related DC/TMD diagnosis and 33% an intra-articular reference DC/TMD diagnosis. Sensitivity for the two pain screening questions was high (0.83-0.94), whereas specificity was low (0.41-0.55). For the function-related question, sensitivity was low (0.48), whereas specificity was high (0.96). In a specialized pain clinic, the two pain questions (Q1, Q2) are positive in most patients with pain-related TMD. Therefore, in case of a positive response, further diagnostic procedures for TMD pain are warranted. For the functional screening question (Q3), a positive response is indicative for an intra-articular DC/TMD diagnosis, while in case of a negative outcome, an intra-articular TMD might still be present.

    Full text: (author)In the construction of physical theories are several paradigms (according to Vladimirov Yu. S.). Depending on the number of entities are used paradigms include trialist (3 entities), dualist (2 entities) and monistic (1 entity). In trialist paradigm uses the following entities: geometry (G), particle (P) and field (F). Go to the dualist paradigms performed in the following ways: two entities take over the functions of the third, two entities merged into a single synthesis. Is also possible to limit the dualistic theory, which summarized the essence in addition assume the functions of a third. In turn, by way of grouping the entities dualistic theory can be divided into geometric (unification of geometry and field), relational (unification of geometry and particles) and field (unification of fields and particles). For the connection of the two theories should be to go to the common denominator: to trialist or monistic theories. Since the monistic theory at the moment completely unknown, may be used only trialist theory. General relativity is a typical representative of the geometric dualistic paradigm. However geometrized only gravity. Other fields non-geometrized. In turn, the relativistic theory of gravitation is a typical trialist theory. To establish a correspondence between theories should to geometrize material field in the general theory of relativity. It is proposed to implement this on the basis of a multi-dimensional Kaluza-Klein theory

    planetary and cosmic consequences. Dignity of man and his work, regarding the global character of economic life, whose bearers are multinational corporations, and global character of job market, regarding preservation of dignity of work as presumption of preservation of dignity of man. However, the question is if the contemporary level of science development allows this, first of all social sciences and especially sociology (which is generally determined as the most general science on society and its totality. In fact, the question is if the theoretical-cognitive apparatus of sociology allows studying of the complex structure and category of contemporary society and their dynamics of changes that are not accompanied by development of suitable idea-terminological apparatus. As Sorokin points out, many theories have appeared in sociology since Auguste Comte that had their boom, and then they were contested and finally disappeared. Considering the problems of sociological theories, it should be born in mind that a 'universal' sociological theory cannot exist because few theoretical-methodological attitudes are not enough to interpret accelerated complexity of social development dynamics, and the society is changing very fast. However, it is possible to specify the theory parameters in the context for valid interpretation of development tendencies of self-development of society. Tendency of postmodernism to make the society in its construction and dynamics by its subject of study, especially by establishing postmodern sociological terminology, indicates tendency that postmodernism paradigm questions the referred determinacy of sociology itself, which has been developed and survived as science on classical terminology. A danger exists that paradigm arisen from tendency to modernize cognitional apparatus of sociology (the terms questions existence of the science itself within which it has originated, i.e. sociology. Therefore, postmodern sociological paradigm should be also

  7. [Beyond the diagnosis of a genetic disease, the question of informing the relatives].

    Science.gov (United States)

    Pellerin, P

    2009-01-01

    The examination of a person's genetic characteristics is not a classic diagnostic. It concerns the gene pool of an entire family. It is valid in the present and may affect some part of the future. The diseases that it reveals, sometime very serious ones, may or may not be treated. But genetic advice allows sometimes to preventing some of these diseases. The 2004 Bioethics Law makes the provision that in case a serious genetic anomaly is diagnosed during the examination of a person's genetic characteristics, the medical doctor informs the person or its legal representative of the risks that his silence could cause to the potentially concerned family members as long as prevention measures or care can be offered to them. For these reasons, besides the specificity of the diagnostic for the person directly concerned, there is also the question of the right of other people, like family members, to be informed of the diagnostic. As such, there is an ethical conflict between medical confidentiality owed to each patient and the duty of information. The pharmacist must know the medical confidentiality rules that frame this information. He must also know the different patient attitudes and must be able to encourage him to inform his family because the future if not the life of others may depend on this information.

  9. Can we share questions? Performance of questions from different question banks in a single medical school.

    Freeman, Adrian; Nicholls, Anthony; Ricketts, Chris; Coombes, Lee

    2010-01-01

    To use progress testing, a large bank of questions is required, particularly when planning to deliver tests over a long period of time. The questions need not only to be of good quality but also balanced in subject coverage across the curriculum to allow appropriate sampling. Hence as well as creating its own questions, an institution could share questions. Both methods allow ownership and structuring of the test appropriate to the educational requirements of the institution. Peninsula Medical School (PMS) has developed a mechanism to validate questions written in house. That mechanism can be adapted to utilise questions from an International question bank International Digital Electronic Access Library (IDEAL) and another UK-based question bank Universities Medical Assessment Partnership (UMAP). These questions have been used in our progress tests and analysed for relative performance. Data are presented to show that questions from differing sources can have comparable performance in a progress testing format. There are difficulties in transferring questions from one institution to another. These include problems of curricula and cultural differences. Whilst many of these difficulties exist, our experience suggests that it only requires a relatively small amount of work to adapt questions from external question banks for effective use. The longitudinal aspect of progress testing (albeit summatively) may allow more flexibility in question usage than single high stakes exams.

  10. Health care cost containment in Denmark and Norway: a question of relative professional status?

    Science.gov (United States)

    Andersen, Lotte B

    2014-04-01

    The demand for publicly subsidized health care services is insatiable, but the costs can be contained in different ways: formal rules can limit access to and the number of subsidized services, demand and supply can be regulated through the price mechanism, the relevant profession can contain the costs through state-sanctioned self-regulation, and other professions can contain the costs (e.g. through referrals). The use of these cost containment measures varies between countries, depending on demand and supply factors, but the relative professional status of the health professions may help explain why different countries use cost containment measures differently for different services. This article compares cost containment measures in Denmark and Norway because these countries vary with regard to the professional status of the medical profession relative to other health care providers, while other relevant variables are approximately similar. The investigation is based on formal agreements and rules, historical documents, existing analyses and an analysis of 360 newspaper articles. It shows that high relative professional status seems to help professions to avoid user fees, steer clear of regulation from other professions and regulate the services produced by others. This implies that relative professional status should be taken into consideration in analyses of health care cost containment.

  13. Application of area-related data and method banks for answering radioecological questions

    International Nuclear Information System (INIS)

    Bruessermann, K.; Bonnenberg, H.; Kayser, J.

    1978-01-01

    Information about the radioecological problems of a site may be obtained in a relatively simple manner with the aid of suitable evaluation programs for analyzing regional neighbouring conditions by storing digitally recorded point data (e.g. distribution of wind directions, sites of nuclear facilities), linear data (e.g. the course of rivers, water divides), and area-related data (e.g. population distribution, nature reserves, natural radiation exposure). Data about the population which would be directly exposed as a result of potential air contamination are gained for the example of an urban and a rural region by superposing meteorological and demographical data with the aid of interactive graphical systems. There is discussed the possibility of calculating by means of the population distribution within the range of the water divides relevant for the site and by using inhabitant-specific discharge data for therapy and diagnosis patients the nuclear-medical prior contamination of the main water source. The results are compared with the measured values and the radiological exposure is estimated according to the principle of the 'maximum annual dose to be expected'.

  15. Communications strategies concerning ethical and environmental questions relative to radioactive waste

    International Nuclear Information System (INIS)

    Ropars, R.

    1996-01-01

    Today, in France, there is a radioactive waste public opinion and communications problem. Although 82 per cent of the population is favourable to the continuation of the French nuclear programme. 73 per cent considers that the truth is not being told about radioactive waste. Radioactive waste is the second ranking argument against nuclear power, after Chernobyl. Since 1991 there has been an official debate, and a national strategy has been set out. At present operational solutions are in existence for 90 per cent of the medium or short-lived waste. What communications strategy should be used? Technical solutions, not philosophical ones, are needed for technical problems, and the companies involved need to show that they can manage them from a technical point of view. However, the ethical component must be seen to be integrated into technical and management choices, as well as into means of communications. A communications policy must first show that ethical considerations are not absent from technical and legal choices, and secondly that they are included in the definition of the communications strategy itself; the paper discusses several possibilities. Companies must stick to their areas of competence, i.e. the technical and scientific fields, that are the only ones within which waste problems can be solved. However, showing that both technical and administrative choices made or envisaged, as well industrial and communications strategies, have an ethical inspiration constitutes a sensible way to go.

  17. A satellite relative motion model including J_2 and J_3 via Vinti's intermediary

    Science.gov (United States)

    Biria, Ashley D.; Russell, Ryan P.

    2018-03-01

    Vinti's potential is revisited for analytical propagation of the main satellite problem, this time in the context of relative motion. A particular version of Vinti's spheroidal method is chosen that is valid for arbitrary elliptical orbits, encapsulating J_2, J_3, and generally a partial J_4 in an orbit propagation theory without recourse to perturbation methods. As a child of Vinti's solution, the proposed relative motion model inherits these properties. Furthermore, the problem is solved in oblate spheroidal elements, leading to large regions of validity for the linearization approximation. After offering several enhancements to Vinti's solution, including boosts in accuracy and removal of some singularities, the proposed model is derived and subsequently reformulated so that Vinti's solution is piecewise differentiable. While the model is valid for the critical inclination and nonsingular in the element space, singularities remain in the linear transformation from Earth-centered inertial coordinates to spheroidal elements when the eccentricity is zero or for nearly equatorial orbits. The new state transition matrix is evaluated against numerical solutions including the J_2 through J_5 terms for a wide range of chief orbits and separation distances. The solution is also compared with side-by-side simulations of the original Gim-Alfriend state transition matrix, which considers the J_2 perturbation. Code for computing the resulting state transition matrix and associated reference frame and coordinate transformations is provided online as supplementary material.

  18. Cyclic nucleotide metabolism including nitric oxide and phosphodiesterase-related targets in the lower urinary tract.

    Uckert, Stefan; Kuczyk, Markus A

    2011-01-01

    The clinical data on the use of the orally active phosphodiesterase (PDE) type 5 inhibitors sildenafil (VIAGRA™), vardenafil (LEVITRA™), and tadalafil (CIALIS™) for the treatment of male erectile dysfunction have boosted research activities on the physiology and pharmacology of the organs of the lower urinary tract (LUT). This includes both intracellular signal transduction in the prostate, urinary bladder (detrusor), and urethra, as well as central brain and spinal cord pathways controlling the function of the LUT. Such efforts provided the basis for the development of new therapeutic modalities into the management of dysfunctions/ syndromes of the LUT, some of which are already offered to the patients. The pharmacological treatment of the overactive bladder and the so-called benign prostatic syndrome, including LUT symptomatology and bladder outlet obstruction secondary to benign prostatic enlargement, has primarily focused on selective, orally available drugs acting by influencing intracellular regulatory mechanisms. These agents are regarded efficacious, have a fast onset of drug action in the target tissue and an improved effect-to-side-effect ratio. Better understanding of the functional significance of proteins related to cyclic nucleotide-dependent pathways, such as nitric oxide synthase, cytosolic and membrane-bound guanylyl cyclases, PDE isoenzymes and cyclic AMP- and cyclic GMP-binding protein kinases, the relative distribution in tissues of the LUT, and the consequences for urogenital function, seems to be of particular interest in order to identify new or more selective pharmacological approaches to manage disorders of the LUT. The present review focuses on cyclic nucleotide-related targets involved in the control of the function of the bladder, prostate, and urethra and the significance of those proteins in the process of evolving new pharmacological options for the treatment of LUT symptoms secondary to benign prostatic hyperplasia as well as

    Crutzen, Rik; Peters, Gjalt-Jorn Y; Portugal, Sarah Dias; Fisser, Erwin M; Grolleman, Jorne J

    2011-05-01

    The aim of this study was to investigate if and how an artificially intelligent chat agent (chatbot) that answers questions about sex, drugs, and alcohol is used and evaluated by adolescents, especially in comparison with information lines and search engines. A sample of 929 adolescents (64% girls, mean age = 15), varying in urbanization level and educational level, participated in this study. Use of the chatbot was objectively tracked through server registrations (e.g., frequency and duration of conversations with the chatbot, the number and topics of queries), and a web-based questionnaire was used to evaluate the chatbot (e.g., the perception of anonymity, conciseness, ease of use, fun, quality and quantity of information, and speed) and to compare it with information lines and search engines. The chatbot reached high school attendees in general and not only adolescents with previous experience related to sex, drugs, or alcohol; this is promising from an informed decision-making point of view. Frequency (M = 11) and duration of conversations (3:57 minutes) was high and the chatbot was evaluated positively, especially in comparison with information lines and search engines. The use of chatbots within the field of health promotion has a large potential to reach a varied group of adolescents and to provide them with answers to their questions related to sex, drugs, and alcohol.

  1. Some Mathematical Structures Including Simplified Non-Relativistic Quantum Teleportation Equations and Special Relativity

    International Nuclear Information System (INIS)

    Woesler, Richard

    2007-01-01

    The computations of the present text with non-relativistic quantum teleportation equations and special relativity are totally speculative, physically correct computations can be done using quantum field theory, which remain to be done in future. Proposals for what might be called statistical time loop experiments with, e.g., photon polarization states are described when assuming the simplified non-relativistic quantum teleportation equations and special relativity. However, a closed time loop would usually not occur due to phase incompatibilities of the quantum states. Histories with such phase incompatibilities are called inconsistent ones in the present text, and it is assumed that only consistent histories would occur. This is called an exclusion principle for inconsistent histories, and it would yield that probabilities for certain measurement results change. Extended multiple parallel experiments are proposed to use this statistically for transmission of classical information over distances, and regarding time. Experiments might be testable in near future. However, first a deeper analysis, including quantum field theory, remains to be done in future

  2. Three-dimensional free electron laser dispersion relation including betatron oscillations

    International Nuclear Information System (INIS)

    Chin, Y.H.; Kim, K.J.; Xie, M.

    1991-08-01

    We have developed a 3-D FEL theory based upon the Maxwell-Vlasov equations including the effects of the energy spread and emittance of the electron beam, and of betatron oscillations. The radiation field is expressed in terms of the Green's function of the inhomogeneous wave equation and the distribution function of the electron beam. The distribution function is expanded in terms of a set of orthogonal functions determined by the unperturbed particle distribution. The coupled Maxwell-Vlasov equations are then reduced to a matrix equation, from which a dispersion relation for the eigenvalues is derived. In the limit of small betatron oscillation frequency, the present dispersion relation reduces to the well-known cubic equation of the one-dimensional theory in the limit of large beam size, and it gives the correct gain in the limit of small beam size. Comparisons of our numerical results with other approaches show good agreement. We present a handy empirical formula for the FEL gain of a 3-D Gaussian beam, as a function of the scaled parameters, that can be used for a quick estimate of the grain. 5 refs., 2 figs

  5. Centrosomes in the zebrafish (Danio rerio: a review including the related basal body

    Directory of Open Access Journals (Sweden)

    Lessman Charles A

    2012-06-01

    Full Text Available Abstract Ever since Edouard Van Beneden and Theodor Boveri first formally described the centrosome in the late 1800s, it has captivated cell biologists. The name clearly indicated its central importance to cell functioning, even to these early investigators. We now know of its role as a major microtubule-organizing center (MTOC and of its dynamic roles in cell division, vesicle trafficking and for its relative, the basal body, ciliogenesis. While centrosomes are found in most animal cells, notably it is absent in most oocytes and higher plant cells. Nevertheless, it appears that critical components of the centrosome act as MTOCs in these cells as well. The zebrafish has emerged as an exciting and promising new model organism, primarily due to the pioneering efforts of George Streisinger to use zebrafish in genetic studies and due to Christiane Nusslein-Volhard, Wolfgang Driever and their teams of collaborators, who applied forward genetics to elicit a large number of mutant lines. The transparency and rapid external development of the embryo allow for experiments not easily done in other vertebrates. The ease of producing transgenic lines, often with the use of fluorescent reporters, and gene knockdowns with antisense morpholinos further contributes to the appeal of the model as an experimental system. The added advantage of high-throughput screening of small-molecule libraries, as well as the ease of mass rearing together with low cost, makes the zebrafish a true frontrunner as a model vertebrate organism. The zebrafish has a body plan shared by all vertebrates, including humans. This conservation of body plan provides added significance to the existing lines of zebrafish as human disease models and adds an impetus to the ongoing efforts to develop new models. In this review, the current state of knowledge about the centrosome in the zebrafish model is explored. Also, studies on the related basal body in zebrafish and their relationship to

  6. Local Staff (LS) - Proposal by the Management, Including related Modifications to the Staff Rules And Regulations

    CERN Document Server

    2003-01-01

    The issue of Local Staff (LS) has been discussed since May 2002 at successive meetings of TREF and the Committees, leading to a proposal document by the Management, which was examined at TREF last November. As reported by the Chairman of TREF to the Finance Committee in December, the Management has now revised its proposal in the light of discussions at the Forum. This document summarises the background, the main aims, scope and features of LS, as well as estimated consequences of implementing the Management's proposal, including those indicated in the Human Resources Plan submitted last December.

    2015-02-01

    We aimed to record all new patients who presented to departments of oral surgery, oral medicine, and oral and maxillofacial surgery, and to dental hospitals in the UK, with avascular necrosis of the jaws including bisphosphonate-related necrosis (BRONJ) over a 2-year period (1 June 2009-31 May 2011). They were eligible irrespective of age, cause, or coexisting conditions. Data on incidence, clinical characteristics, risk factors, and coexisting conditions were collected. A total of 383 cases were registered: 369 were described as BRONJ, 5 as avascular necrosis, and 9 were unknown. Bisphosphonates had been given orally in 207 (56%), intravenously in 125 (34%), both orally and intravenously in 27 (7%), and was unknown in 9 (2%); one had been given denosumab. The main risk factor was dental extraction, and the mandible was commonly affected. The median duration of administration until onset of BRONJ was 3 years in those treated intravenously and 4 years in those treated orally. Levels of engagement with the study varied between regions, and extrapolation from the 2 most involved (Merseyside and Northern Ireland) found around 8.2-12.8 cases/million/year, which is 508-793 patients/year across the UK. To our knowledge this is one of the first studies to estimate national rates of BRONJ. It confirms that the risk and incidence are low. With changes in trends for antiresorptive bone medication, and increasing numbers of elderly people, it would be useful to repeat the registration in the future.

  8. Completion of the universal I-Love-Q relations in compact stars including the mass

    Science.gov (United States)

    Reina, Borja; Sanchis-Gual, Nicolas; Vera, Raül; Font, José A.

    2017-09-01

    In a recent paper, we applied a rigorous perturbed matching framework to show the amendment of the mass of rotating stars in Hartle's model. Here, we apply this framework to the tidal problem in binary systems. Our approach fully accounts for the correction to the Love numbers needed to obtain the universal I-Love-Q relations. We compute the corrected mass versus radius configurations of rotating quark stars, revisiting a classical paper on the subject. These corrections allow us to find a universal relation involving the second-order contribution to the mass δM. We thus complete the set of universal relations for the tidal problem in binary systems, involving four perturbation parameters, namely I, Love, Q and δM. These relations can be used to obtain the perturbation parameters directly from observational data.

    Choosing to train as a nurse is a major decision, rife with different emotions and considerations. Regardless of what point you have reached in your studies, whether you are studying towards a degree or diploma, whatever your age and whether you are from the UK or overseas, you face common challenges. These include surviving financially, juggling study and clinical placements, learning new information and addressing patients' needs. While the profession certainly offers exciting opportunities, nursing students in 2006 face a range of uncertainties. There have been cuts and freezes to existing and vacant posts across NHS trusts, while students from overseas face the additional problem that band 5 and 6 nursing posts have been removed from the Home Office's shortage occupation list. Will there be enough mentors to teach students? Will there be jobs when they qualify? How can students survive financially? Will overseas students be able to stay once qualified? NT put students' key questions to a panel of experts and influential figures.

    Sentiment includes emotional and enduring attitudinal features of contempt, but explaining contempt as a mixture of basic emotion system affects does not adequately address the family resemblance structure of the concept. Adding forms of individual, group-based, and widely shared arrogance and contempt is necessary to capture the complex mixed feelings of proud superiority when "looking down upon" and acting harshly towards others.

    We found that exposure of mice and rats to male but not female experimenters produces pain inhibition. Male-related stimuli induced a robust physiological stress response that results in stress-induced analgesia. This effect could be replicated with T-shirts worn by men, bedding material from gonadally intact and unfamiliar male mammals, and presentation of compounds secreted from the human axilla. Experimenter sex can thus affect apparent baseline responses in behavioral testing.

  18. Using multiple data sources to answer patient safety-related research questions in hospital inpatient settings: a discursive paper using inpatient falls as an example.

    Science.gov (United States)

    Tzeng, Huey-Ming

    2011-12-01

    This education-focused paper presents a discussion of possible data sources used in patient safety issues specific to fall reduction in hospital inpatient care settings. Although hospitals and clinicians in the USA have been implored to improve care and reduce events that harm patients (falls), studies to date have failed to clearly address the facility system-level factors for falls. Making meaningful approaches to modify risk factors is clearly overdue. Discursive paper. Possible data sources for answering patient fall-related research questions in hospital settings are categorised as: (1) archived hospital data, (2) surveys of patients/families/clinicians, (3) interviews and focus groups of patients/families/clinicians, (4) publicly available data sets and (5) published legal cases. The complexities of research in fall prevention are illustrated using the conceptual models. Examples were included to illustrate the use of these data sources. Data-related issues include: (1) unit of analysis, (2) computer data processing capabilities, (3) merging data sets from different sources and (4) data abstraction, aggregation and data analytic techniques. The trend to use multiple data sources to answer research questions is gradually emerging. To demonstrate effective fall prevention efforts across hospitals, publicly available data sets can be reliable sources for analyses to inform policymakers about meaningful fall prevention programmes that result in positive outcomes. Challenges to develop and evaluate any interventions to eliminate risk factors for falls often relate to selecting feasible interventions and whether staff members accept the interventions and adhere to adopting the intervention. Using multiple data sources with time factors to cross-validate the sufficiency of nurses' knowledge with their practice patterns may be more productive. This need further supports the importance of this paper about possible data sources used in the research on patient safety

  19. The role of calcitonin gene-related peptide in peripheral and central pain mechanisms including migraine.

    2017-04-01

    Calcitonin gene-related peptide (CGRP) is a 37-amino acid peptide found primarily in the C and Aδ sensory fibers arising from the dorsal root and trigeminal ganglia, as well as the central nervous system. Calcitonin gene-related peptide was found to play important roles in cardiovascular, digestive, and sensory functions. Although the vasodilatory properties of CGRP are well documented, its somatosensory function regarding modulation of neuronal sensitization and of enhanced pain has received considerable attention recently. Growing evidence indicates that CGRP plays a key role in the development of peripheral sensitization and the associated enhanced pain. Calcitonin gene-related peptide is implicated in the development of neurogenic inflammation and it is upregulated in conditions of inflammatory and neuropathic pain. It is most likely that CGRP facilitates nociceptive transmission and contributes to the development and maintenance of a sensitized, hyperresponsive state not only of the primary afferent sensory neurons but also of the second-order pain transmission neurons within the central nervous system, thus contributing to central sensitization as well. The maintenance of a sensitized neuronal condition is believed to be an important factor underlying migraine. Recent successful clinical studies have shown that blocking the function of CGRP can alleviate migraine. However, the mechanisms through which CGRP may contribute to migraine are still not fully understood. We reviewed the role of CGRP in primary afferents, the dorsal root ganglion, and in the trigeminal system as well as its role in peripheral and central sensitization and its potential contribution to pain processing and to migraine.

    The two approaches of consistent quantum field theory for systems of the trapped Bose-Einstein condensates are known, one is the Bogoliubov-de Gennes approach and the other is the generalized Bogoliubov approach. In this paper, we investigate the relation between the two approaches and show that they are formally equivalent to each other. To do this one must carefully treat the Nambu-Goldstone mode which plays a crucial role in the condensation. It is emphasized that the choice of vacuum is physically relevant

  1. Possible Simple Structures of the Universe to Include General Relativity Effects

    Directory of Open Access Journals (Sweden)

    Corneliu BERBENTE

    2017-12-01

    Full Text Available The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, g  , which should be in agreement with a mass (or energy tensor in order to satisfy the Einstein equation of the general relativity [1]. This equation contains the Ricci curvature as well. In general, applications are done considering that a chosen metric is valid without region limits. In fact, the density of the energy whose distribution is however unknown is variable in universe; therefore, the metrics need to be adapted to different regions. For this reason one suggests to start with a simple, average mass-energy distribution that could represent in a first step the actual universe. This suggestion is in agreement with the symmetrical distribution of equal spheres existing in a model of the early universe given by one of the authors. Two kinds of distribution are given. The possibility of black holes formation is studied and a criterion is given.

    Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant, extremely resistant to environmental degradation and is ubiquitous in the environment. Traditional monitoring studies for persistent chemicals failed to identify this contaminant for a long time because of its unique physicochemical properties and its tendency to bind to proteins instead of accumulating in fatty tissues. PFOS is known to be toxic in laboratory animals (rats, mice, monkeys) at levels close to the range already found in organisms and people. PFOS has been commercially produced by an electrochemical fluorination process for over 40 years. Perfluorooctane sulfonylfluoride (POSF; C{sub 8}F{sub 17}SO{sub 2}F) is used as a building block for further reactions that produce several other sulfonated fluorinated compounds, including perfluorooctane sulfonate (C{sub 8}F{sub 17}SO{sub 3}{sup -}) and other precursor molecules such as n-ethyl or n-methyl perfluorooctanesulfonamidoethanol. POSF-based fluorochemicals have been used in a wide variety of industrial and consumer products, including protective coatings for carpets and apparel, paper coatings, insecticide formulations, and surfactants. These compounds repel water and oil, reduce surface tension, catalyze oligomerization and polymerization, and maintain their properties under extreme conditions. Depending upon the specific functional derivatization or the degree of polymerization, POSF-based chemicals may degrade or metabolize to PFOS, which is known to be the final metabolite of POSF-based fluorochemicals. PFOS is stable, chemically inert, and non-reactive and has the potential to bioaccumulate. It has been found in polar bears from the Arctic, albatross and other fish-eating water birds in the mid-Pacific, and aquatic organisms11 and people world-wide. PFOS and other perfluorinated chemicals such as perfluorooctanesulfonamide (PFOSA), perfluorohexanesulfonate (PFHxS), and perfluorooctanoate (PFOA) have been detected in human blood. In

    Type 2 diabetes (T2D) is a disease of relative insulin deficiency resulting from both insulin resistance and beta cell failure. We have previously used heterogeneous stock (HS) rats to fine-map a locus for glucose tolerance. We show here that glucose intolerance in the founder strains of the HS colony is mediated by different mechanisms: insulin resistance in WKY and an insulin secretion defect in ACI, and we demonstrate a high degree of variability for measures of insulin resistance and insulin secretion in HS rats. As such, our goal was to use HS rats to fine-map several diabetes-related traits within a region on rat chromosome 1. We measured blood glucose and plasma insulin levels after a glucose tolerance test in 782 male HS rats. Using 97 SSLP markers, we genotyped a 68 Mb region on rat chromosome 1 previously implicated in glucose and insulin regulation. We used linkage disequilibrium mapping by mixed model regression with inferred descent to identify a region from 198.85 to 205.9 that contains one or more quantitative trait loci (QTL) for fasting insulin and a measure of insulin resistance, the quantitative insulin sensitivity check index. This region also encompasses loci identified for fasting glucose and Insulin_AUC (area under the curve). A separate <3 Mb QTL was identified for body weight. Using a novel penalized regression method we then estimated effects of alternative haplotype pairings under each locus. These studies highlight the utility of HS rats for fine-mapping genetic loci involved in the underlying causes of T2D.

    The majority of ovarian cancer patients relapse after surgical resection. Evidence is accumulating regarding the role of surgery in disseminating cancer cells; in particular anaesthesia may have an impact on cancer re-occurrence. Here, we have investigated the metastatic potential of volatile anaesthetics isoflurane, sevoflurane and desflurane on ovarian cancer cells. Human ovarian carcinoma cells (SKOV3) were exposed to isoflurane (2%), sevoflurane (3.6%) or desflurane (10.3%) for 2 hours. Metastatic related gene expression profiles were measured using the Tumour Metastasis PCR Array and qRT-PCR. Subsequently vascular endothelial growth factor A (VEGF-A), matrix metalloproteinase 11 (MMP11), transforming growth factor beta-1 (TGF-β1) and chemokine (C-X-C motif) receptor 2 (CXCR2) proteins expression were determined using immunofluorescent staining. The migratory capacities of SK-OV3 cells were assessed with a scratch assay and the potential role of CXCR2 in mediating the effects of volatile anaesthetics on cancer cell biology were further investigated with CXCR2 knockdown by siRNA. All three volatile anaesthetics altered expression of 70 out of 81 metastasic related genes with significant increases in VEGF-A, MMP-11, CXCR2 and TGF-β genes and protein expression with a magnitude order of desflurane (greatest), sevoflurane and isoflurane. Scratch analysis revealed that exposure to these anesthetics increased migration, which was abolished by CXCR2 knockdown. Volatile anaesthetics at clinically relevant concentrations have strong effects on cancer cell biology which in turn could enhance ovarian cancer metastatic potential. This work raises the urgency for further in vivo studies and clinical trials before any conclusions can be made in term of the alteration of clinical practice.

    The purpose of this study was to describe the impact of a genomic educational intervention by measuring the extent participants could apply the class content to practice. A sample of 76 nurses employed by Singapore Health Services, Singapore, participated in a nursing genomics seminar in 2008 and completed a survey form with a response rate of 89%. Every respondent was able to identify use of a genomic assessment or intervention item with a patient from their clinical practice. The mean use of genomic assessment and intervention items was 5.8 out of a possible 10. The most frequently used items were assessment of family history information, environmental factors and genomic physical findings. Findings provide evidence that nurses are able to include genomic assessments and interventions in their practice following targeted education. This study highlights how informed nurses are able to apply genomic assessments and interventions to individualize patient care.

    Elucidating differences in social-behavioral profiles of children with comorbid presentations, utilizing caregiver as well as teacher reports, will refine our understanding of how contextual symptoms vary across anxiety-related disorders. In our pediatric anxiety clinic, the most frequent diagnoses and comorbidities were mixed anxiety (MA; ≥ 1 anxiety disorder; N = 155), anxiety with comorbid attention-deficit hyperactivity disorder (MA/ADHD, N = 47) and selective mutism (SM, N = 48). Behavioral measures (CPRS, CTRS) were analyzed using multiple one-way multivariate analyses of covariance tests. Differences between the three diagnostic groups were examined using completed parent and teacher reports (N = 135, 46, and 48 for MA, MA/ADHD, and SM groups, respectively). Comparisons across the MA, MA/ADHD, and SM groups indicate a significant multivariate main effect of group for caregiver and teacher responses (P < 0.01). Caregivers reported that children with SM are similar in profile to those with MA, and both groups were significantly different from the MA/ADHD group. Teachers reported that children with SM had more problems with social behaviors than with the MA or MA/ADHD groups. Further comparison indicates a significant main effect of group (P < 0.001), such that children with SM have the greatest differences in behavior observed by teachers versus caregivers. Clinical profiles between MA/ADHD, MA, and SM groups varied, illustrating the importance of multi-rater assessment scales to capture subtle distinctions and to inform treatment planning given that comorbidities occur frequently in children who present with anxiety. © 2013 Wiley Periodicals, Inc.

    Objective. To determine forms of female genital mutilation (FGM), assess consistency between self-reported and observed FGM status, and assess the accuracy of Demographic and Health Surveys (DHS) FGM questions in Sierra Leone. Methods. This cross-sectional study, conducted between October 2010 and April 2012, enrolled 558 females aged 12–47 from eleven antenatal clinics in northeast Sierra Leone. Data on demography, FGM status, and self-reported anatomical descriptions were collected. Genital inspection confirmed the occurrence and extent of cutting. Results. All participants reported FGM status; 4 refused genital inspection. Using the WHO classification of FGM, 31.7% had type Ib; 64.1% type IIb; and 4.2% type IIc. There was a high level of agreement between reported and observed FGM prevalence (81.2% and 81.4%, resp.). There was no correlation between DHS FGM responses and anatomic extent of cutting, as 2.7% reported pricking; 87.1% flesh removal; and 1.1% that genitalia was sewn closed. Conclusion. Types I and II are the main forms of FGM, with labia majora alterations in almost 5% of cases. Self-reports on FGM status could serve as a proxy measurement for FGM prevalence but not for FGM type. The DHS FGM questions are inaccurate for determining cutting extent. PMID:24204384

    Accuracy of measurement is a cornerstone of research in order to make robust conclusions about the research hypothesis. To examine whether the number of items (questions) and the number of consumption responses (the coding used to measure the frequency of consumption) included in nutritional assessment tools influence their repeatability. During 2009, 400 participants (250 from Greece, mean age 37 +/- 13 years, 34% males, and 150 from Spain, mean age 39 +/- 17 years, 41% males) completed a diet index with 11 items and binary (yes/ no) responses, a diet index with 11 items and 6-scale responses, and 36-item and 76-item food frequency questionnaires (FFQs) with 6-scale responses. The participants completed these tools twice, with 15 days between the two administrations of the tools. The Spearman-Brown coefficient (r(sb)), Kendall's tau coefficients, and the Bland-Altman method were applied to answer the research hypothesis. The highest repeatability coefficient was observed for the diet index with 11 items and binary (yes/no) responses (r(sb) = 0.948, p tools (p > .23), whereas these three tools had significantly higher repeatability coefficients than the 76-item FFQ (p = .002). Subgroup analyses by sex, education, smoking, and clinical status confirmed these results. Repeatability was found for all food frequency assessment tools used, irrespective of the number of items or the number of responses included.

    The development of effective health care and public health interventions requires a comprehensive understanding of the perceptions, concerns, and stated needs of health care consumers and the public at large. Big datasets from social media and question-and-answer services provide insight into the public's health concerns and priorities without the financial, temporal, and spatial encumbrances of more traditional community-engagement methods and may prove a useful starting point for public-engagement health research (infodemiology). The objective of our study was to describe user characteristics and health-related queries of the ChaCha question-and-answer platform, and discuss how these data may be used to better understand the perceptions, concerns, and stated needs of health care consumers and the public at large. We conducted a retrospective automated textual analysis of anonymous user-generated queries submitted to ChaCha between January 2009 and November 2012. A total of 2.004 billion queries were read, of which 3.50% (70,083,796/2,004,243,249) were missing 1 or more data fields, leaving 1.934 billion complete lines of data for these analyses. Males and females submitted roughly equal numbers of health queries, but content differed by sex. Questions from females predominantly focused on pregnancy, menstruation, and vaginal health. Questions from males predominantly focused on body image, drug use, and sexuality. Adolescents aged 12-19 years submitted more queries than any other age group. Their queries were largely centered on sexual and reproductive health, and pregnancy in particular. The private nature of the ChaCha service provided a perfect environment for maximum frankness among users, especially among adolescents posing sensitive health questions. Adolescents' sexual health queries reveal knowledge gaps with serious, lifelong consequences. The nature of questions to the service provides opportunities for rapid understanding of health concerns and may

    Full Text Available The article discusses the development of relations between the Russian and Constantinople Churches during the rule of the Saint Patriarch Tikhon (1917–1925. Originated in the Greek environment after the defeat of Turkey in World war I the plans for the transformation of Constantinople into the «real pan-Orthodox centre» and surrender to him the rest of the local Churches led to the development of an unprecedented expansion of the Ecumenical Patriarchate in the world, mostly due to the capture of dioceses and parishes of the Russian Church. In order to turn the primacy of honour in the Orthodox world in championship power Constantinople was interested in the weakening of the Moscow Patriarchate. Simultaneously, from 1922 began to show the desire of the Phanar (Constantinople Patriarchate to enlist the support of the Soviet government in relations with the government of Turkey, as well as addressing the aggravated financial problems of the Ecumenical Patriarchate. Taken together, these reasons led to open transition of the Constantinople Patriarchate on the side of the Renovationist schism in Russia in 1924, which made the preservation of canonical communion with him for the Russian Orthodox Church is virtually impossible.

    Access barriers to effective ethics review continue to be a significant challenge for researchers and community-based organizations undertaking community-based participatory research (CBPR). This article reports on findings from a content analysis of select (Behavioural, Biomedical, Social Sciences, Humanities) research ethics boards (REBs) in the Canadian research context (n = 86). Existing ethics review documentation was evaluated using 30 CBPR related criteria for their sensitivity to relevant approaches, processes, and outcomes. A linear regression was conducted to determine whether specific organizational characteristics have an impact on the CBPR sensitivity: (1) region of Canada, (2) type of institution (university or a healthcare organization), (3) primary institutional language (English or French) and (4) national ranking with respect to research intensiveness. While only research intensiveness proved statistically significant (p = .001), we recognize REB protocol forms may not actually reflect how CBPR is reviewed. Despite using a single guiding ethical framework, REBs across Canada employ a variety of techniques to review research studies. We report on these differences and varying levels of sensitivity to CBPR. Finally, we highlight best practices and make recommendations for integrating CBPR principles into existing ethics review.

  8. More than just a question of technology: factors related to hospitals' adoption and implementation of health information exchange.

    Science.gov (United States)

    Vest, Joshua R

    2010-12-01

    The provisions of the American Recovery & Reinvestment Act increased the likelihood of more widespread health information exchange (HIE), the electronic transfer of patient-level information between organizations, by essentially mandating the use of electronic health record systems. While important, the sparse body of research on HIE efforts and anecdotal reports indicate the barriers to HIE adoption and implementation include factors beyond simply the presence or absence of a specific technology. This paper examines those technological, organizational, and environmental factors that are associated with both HIE adoption and implementation in a sample of 4830 U.S. hospitals. Factors associated with adoption and implementation were modeled using random-intercept logistic regression. Consistent with a perspective that adoption and implementation are different phenomena, many factors associated with an increased odds of adoption, were unassociated with implementation and vice versa. Non-profit status, public hospitals, more live and operation applications, more emergency room visits, network membership, and the presence of physician portals all increased hospitals' odds of HIE adoption. However, only network membership increased the odds of HIE implementation, whereas competition decreased those odds significantly. This study agreed with earlier case-studies and anecdotal reports that factors beyond technology were important to both adoption and implementation. While current U.S. policy on healthcare information technology adoption focuses on technological barriers, many other non-technological factors may ultimately hinder effective HIE.

    2017-03-19

    Taking an image and question as the input of our method, it can output the text-based answer of the query question about the given image, so called Visual Question Answering (VQA). There are two main modules in our algorithm. Given a natural language question about an image, the first module takes the question as input and then outputs the basic questions of the main given question. The second module takes the main question, image and these basic questions as input and then outputs the text-based answer of the main question. We formulate the basic questions generation problem as a LASSO optimization problem, and also propose a criterion about how to exploit these basic questions to help answer main question. Our method is evaluated on the challenging VQA dataset and yields state-of-the-art accuracy, 60.34% in open-ended task.

    Eradication of hepatitis C virus (HCV) with interferon (IFN)-based therapy has been reported to reduce all-cause mortality in patients with chronic HCV infection. However, the impact of HCV eradication on non-liver-related mortality and causes of death has not been sufficiently investigated in patients with progressive HCV-related fibrosis. We enrolled 784 chronic HCV patients with progressive liver fibrosis (aspartate aminotransferase to platelet ratio index >1). Cause of death, incidence of hepatocellular carcinoma, and all-cause mortality including non-liver-related mortality were analyzed. Of these 784 patients, 170 achieved sustained virological response (SVR) (eradication of HCV) with IFN-based therapy (IFN-SVR), and 614 did not receive IFN-based therapy (non-IFN patients, chronic HCV infection). The median follow-up duration was 10.3 years. Two hundred seventy-three patients died during follow-up (liver-related death, n = 171; non-liver-related death, n = 102). The mortality rate from non-liver-related disease was 63.6% (7/11) in IFN-SVR patients and 36.3% (95/262) in non-IFN patients, respectively. In multivariate analysis, the eradication of HCV associated with not only hepatocellular carcinoma incidence (hazard ratio (HR), 0.162; 95% confidence interval (CI), 0.092-0.284), and all-cause mortality (HR, 0.094; 95% CI, 0.047-0.187), but non-liver-related mortality (HR, 0.286; 95% CI, 0.127-0.644) as well. Eradication of HCV reduced both liver-related and non-liver-related mortality in patients with progressive HCV-related fibrosis. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Microbial components activate the host's innate immunity via interactions with molecules including TLRs and NODs. We previously reported that in mice (i) Escherichia coli lipopolysaccharide (LPS; TLR4 agonist) promotes Ni-allergy even in T-cell-deficient mice, (ii) E. coli LPS reduces the minimum allergy-inducing concentrations of Ni at both the sensitization and elicitation steps, and (iii) various microbe-related substances promote sensitization to Ni. Here, we examined the effects of microbe-related substances at the elicitation step. Mice (except for TLR4-mutated C3H/HeJ mice) were sensitized to Ni by intraperitoneal injection of NiCl(2) + E. coli LPS. Ten days later their ear-pinnas were challenged with 1 μM NiCl(2) with or without a test substance. Although NiCl(2) alone at this concentration does not induce Ni-allergy, its combination with the following substances induced Ni-allergy in BALB/c mice: LPS preparations from oral gram-negative bacteria (Prevotella intermedia and Porphyromonas gingivalis), a mannan preparation from a fungus (Saccharomyces cerevisiae), and synthetic NOD2 and TLR2 agonists. The effect of the mannan preparation was small in C3H/HeJ mice (sensitized with NiCl(2) + the P. intermedia preparation). The P. intermedia preparation promoted Ni-allergy in C3H/HeJ and nude mice, but not in mice deficient in either TLR2 or histidine decarboxylase. Intragingival injection of the P. intermedia preparation and later challenge with NiCl(2) alone to ear-pinnas also promoted Ni-allergy. These results indicate that (i) in Ni-allergy, a microbial milieu or innate immunity is important at the elicitation step, too, and (ii) some oral bacteria may promote Ni-allergy via TLR2-stimulant(s) production.

    A 51-year-old woman diagnosed as having left breast cancer with axillary lymph node and liver metastases seven years earlier was seen in our office because of severe pancytopenia. She had received chemotherapy including several cycles of doxorubicin plus cyclophosphamide and docetaxel followed by hormone therapy containing leuprorelin and tamoxifen over four years. For management of bone pain due to metastasis, she had also undergone stereotaxic radiation therapy of the neck one and a half years earlier and unsealed internal radiation therapy with (89)Sr injection five months prior to the current presentation, Subsequently, myelosuppression progressively worsened and she finally required a blood transfusion. Although bone marrow examination showed severe hypoplasia, but neither blastic nor dysplastic, a test for PML-RARA fluorescence in situ hybridization was positive. After administration of all-trans retinoic acid, hematogenesis improved within three weeks. Neither disseminated intravascular coagulation nor retinoic acid syndrome was observed during the course of her illness. This is the first report describing acute promyelocytic leukemia after administration of (89)Sr, to our knowledge, and with an atypical onset and progression. As the number of cancer survivors increases due to improvements in medical intervention, clinicians must take more notice of special characteristics of therapy-related leukemia modified by previous treatments.

Contemporary as well as the 19th century debates about the social dimension and the social question deal with social integration. The recent London Communiqué of Ministers emphasizes the importance of the social dimension in higher education in terms of fostering social cohesion, reducing inequalities...... the diversity of relevant populations “without obstacles related to their social and economic background”. In the 19th century the social question was raised in a context of industrialization of societies.

    Full Text Available The first Romanian modern Constitution of 1866 generated – by its restrictive character towards the political and civil rights of the non-Christian citizens in the country – a problem more and more complicated for the governmental circles from Bucharest and for Romanian diplomacy, too. The development of the so called „Jewish question” from an internal economic and social problem into a external political one was produced at the initiative and with large support of the World Jewish Alliance (founded in Paris in 1860. Together with the American Independent Order „B’nai B’rith”, the two organizations succeded to initiate and develop, by various means, a strong diplomatic pressure against Romania, in order to require her to respect proper obligations assumed by the decisions of the Congress of Berlin in 1878. The beginning of that pressure was marked by the American diplomats, either from Constantinopol, Bucharest or Washington D.C., and increased constantly up to the first decade of the XX-th Century. Otherwise, all the diplomatic and economic relations between the United States of America and Romania, since 1866 up to the end of the First World War, were dependent by the attitude of the decisional political factors from Bucharest on the Jewish question. The situation did not improve with the coming of the new Century, and in fact worsened. To the reasons already existing for the low level of bilateral relations, another aggravating element of economic and social nature was added, but dressed in strident political terms.The Jewish question was again revitalized, fostered by immigration to America, with its maximum intensity situated around the turn of the century, when the American authorities reacted in a manner and used means rejected by the Romanian political class and which were not shared by the majority of European powers. The cause was a diplomatic Appeal launched in 1902 by the American Secretary of State, John Hay, seeking

  18. Robustness Analysis of Visual Question Answering Models by Basic Questions

    KAUST Repository

    Huang, Jia-Hong

    2017-11-01

    Visual Question Answering (VQA) models should have both high robustness and accuracy. Unfortunately, most of the current VQA research only focuses on accuracy because there is a lack of proper methods to measure the robustness of VQA models. There are two main modules in our algorithm. Given a natural language question about an image, the first module takes the question as input and then outputs the ranked basic questions, with similarity scores, of the main given question. The second module takes the main question, image and these basic questions as input and then outputs the text-based answer of the main question about the given image. We claim that a robust VQA model is one, whose performance is not changed much when related basic questions as also made available to it as input. We formulate the basic questions generation problem as a LASSO optimization, and also propose a large scale Basic Question Dataset (BQD) and Rscore (novel robustness measure), for analyzing the robustness of VQA models. We hope our BQD will be used as a benchmark for to evaluate the robustness of VQA models, so as to help the community build more robust and accurate VQA models.

    To investigate online search activity of suicide-related words in South Korean adolescents through data mining of social media Web sites as the suicide rate in South Korea is one of the highest in the world. Out of more than 2.35 billion posts for 2 years from January 1, 2011 to December 31, 2012 on 163 social media Web sites in South Korea, 99,693 suicide-related documents were retrieved by Crawler and analyzed using text mining and opinion mining. These data were further combined with monthly employment rate, monthly rental prices index, monthly youth suicide rate, and monthly number of reported bully victims to fit multilevel models as well as structural equation models. The link from grade pressure to suicide risk showed the largest standardized path coefficient (beta = .357, p adolescents' suicide risk.

    We developed a web-based question prompt sheet (QPS) to support information provision of health-related quality of life (HRQL) topics after oesophageal cancer surgery. The QPS was evaluated and updated in three consecutive studies. In Study 1, eight patients were guided in using the QPS. Feasibility was assessed by cognitive walkthrough, questionnaire and interview. We obtained 430 notes (217 negative, 213 positive) of patients' actions and or remarks, and 91 suggestions. With minor support, most patients were able to use the QPS. In Study 2, forty patients independently used and appraised a modified version of the QPS by questionnaire. All patients deemed the QPS to be usable and useful. In Study 3, 21 patients and three surgeons used the QPS in clinical practice. Clinical feasibility was assessed by the number of QPS sent to the researcher/surgeon. Patients and surgeons were surveyed and the follow-up consultation was audio-recorded. Surgeons were additionally interviewed. Twenty/fourteen patients sent their QPS to the researcher/surgeon. Five QPSs were read by the consultation surgeon. Patients considered the QPS usable and useful. Surgeons considered the QPS of added value and helpful in informing patients, but currently not clinically feasible due to increased consultation time. © 2016 John Wiley & Sons Ltd.

    To assess decisions to forego life-sustaining treatment (LST) in patients too sick for intensive care unit (ICU) admission, comparatively to patients admitted to the ICU. Prospective observational cohort study. A medical-surgical ICU. Consecutive patients referred to the ICU during a one-yr period. None. Of 898 triaged patients, 147 were deemed too well to benefit from ICU admission. Decisions to forego LST were made in 148 of 666 (22.2%) admitted patients and in all 85 patients deemed too sick for ICU admission. Independent predictors of decisions to forego LST at ICU refusal rather than after ICU admission were: age; underlying disease; living in an institution; preexisting cognitive impairment; admission for medical reasons; and acute cardiac failure, acute central neurologic illness, or sepsis. Hospital mortality after decisions to forego LST was not significantly different in refused and admitted patients (77.5% vs. 86.5%; p = .1). Decisions to forego LST were made via telephone in 58.8% of refused patients and none of the admitted patients. Nurses caring for the patient had no direct contact with the ICU physicians for 62.3% of the decisions in refused patients, whereas meetings between nurses and physicians occurred in 70.3% of decisions to forego LST in the ICU. Patients or relatives were involved in 28.2% of decisions to forego LST at ICU refusal compared with 78.4% of decisions to forego LST in ICU patients (p refused patients (vs. none of admitted patients) and were associated with less involvement of nurses and relatives compared with decisions in admitted patients. Further work is needed to improve decisions to forego LST made under the distinctive circumstances of triage.

    Conspicuous facial pores are one type of serious aesthetic defects for many women. However, the mechanism(s) that underlie the conspicuousness of facial pores remains unclear. We previously characterized the epidermal architecture around facial pores that correlates with the appearance of those pores in various ethnic groups including Japanese. The goal of this study was to evaluate the possible relationships between facial pore size, the severity of impairment of epidermal architecture around facial pores and sebum output levels to investigate the possible role of IGF-1 in the pathogenesis of conspicuous facial pores. The subjects consisted of 38 healthy Japanese women (aged 22-41 years). IGF-1 was measured using immunoradiometric assay. Surface replicas were collected to compare pore sizes of cheek skin and horizontal cross-section images of cheek skin were obtained non-invasively from the same subjects using in vivo confocal laser scanning microscopy and the severity of impairment of epidermal architecture around facial pores was determined. The skin surface lipids of each subject were collected from their cheeks and lipid classes were determined using gas chromatography/flame ionization detection. The serum level of IGF-1 correlated significantly with total pore area (R = 0.36, P facial pores (R = 0.43, P pore area (R = 0.32, P facial skin characteristics including facial pore size and with the severity of impairment of epidermal architecture around facial pores. © 2010 The Authors.

    Full Text Available The variations in ground beetles (Coleoptera: Carabidae assemblages across the three types of farmland habitats, arable land, meadows and woody vegetation were studied in relation to vegetation cover structure, intensity of agrotechnical interventions and selected soil properties. Material was pitfall trapped in 2010 and 2011 on twelve sites of the agricultural landscape in the Prešov town and its near vicinity, Eastern Slovakia. A total of 14,763 ground beetle individuals were entrapped. Material collection resulted into 92 Carabidae species, with the following six species dominating: Poecilus cupreus, Pterostichus melanarius, Pseudoophonus rufipes, Brachinus crepitans, Anchomenus dorsalis and Poecilus versicolor. Studied habitats differed significantly in the number of entrapped individuals, activity abundance as well as representation of the carabids according to their habitat preferences and ability to fly. However, no significant distinction was observed in the diversity, evenness neither dominance. The most significant environmental variables affecting Carabidae assemblages species variability were soil moisture and herb layer 0-20 cm. Another best variables selected by the forward selection were intensity of agrotechnical interventions, humus content and shrub vegetation. The other from selected soil properties seem to have just secondary meaning for the adult carabids. Environmental variables have the strongest effect on the habitat specialists, whereas ground beetles without special requirements to the habitat quality seem to be affected by the studied environmental variables just little.

    Each nation's laws should prohibit development, acquisition, or transfer of WMD-critical items and should make it a crime to violate that prohibition for hostile purposes. Thus, WMD proliferation should be illegal everywhere, powerfully reinforcing the norm against acquisition of such weapons as well as facilitating law enforcement and trans-national legal cooperation. Provisions applicable to threats should be harmonized. National laws should address threats and should ensure prosecution of offenders or extradition to another State for prosecution. The scope of legal jurisdiction over such crimes should broadly reach the behaviour of legal entities in trans-national smuggling and weapons development conspiracies. A priority question is precisely which activity should constitute a criminal offence. It is relatively straightforward to make the use of WMD a crime; but it will be necessary to reach preparatory steps that can encompass innocent behaviour or even legitimate scientific inquiry. Bio-terror preparations, for example, may employ the same materials, equipment and techniques as undertaking legitimate disease research. Standards must be developed to instruct law enforcers as to what behaviour merits criminal investigation to prevent a hostile attack. Similarly, legal measures must define 'WMD' items, including chemical and biological agents that are non-lethal but incapacitating to humans as well as agents that are lethal as to animal or plant life. If WMD proliferation is criminalized, each State's law enforcement officials must work jointly with their counterparts in other States by sharing information, conducting investigations, and prosecuting apprehended terrorists. State cooperation both in gathering intelligence and using that information to prevent criminal activity is undermined, however, by lack of coherent legal instruments. Currently, there is no integrated database of State laws concerning production or use of WMD; it is difficult to know what

    Prior studies have demonstrated superiority of the combined sensory index (CSI) algorithm in diagnosing mild carpal tunnel syndrome (CTS) and have compared presenting symptoms to CTS grade. However, CTS symptoms, signs, and outcomes, including CSI-diagnosed cases, have not been compared with CTS grade. We retrospectively studied 294 CTS hands from 2010 to 2013; stratified them into mild, moderate, and severe grades; and analyzed the association between CTS grade and presenting symptoms/signs and outcomes. Sensorimotor symptoms (P = 0.017) and signs (P < 0.001) were significantly associated with CTS grade. Regardless of CTS grade, 94% of hands improved with surgery compared with 42% with conservative treatment (P < 0.001). Even in mild CTS, 100% improved with surgery vs. 33% with conservative management (P = 0.011). These results corroborate prior studies that compared symptoms to CTS grade and suggest that more objective signs associate even better. CTS grades associate with outcomes, but additional studies are required. Muscle Nerve 57: 45-48, 2018. © 2017 Wiley Periodicals, Inc.

    Little is known about the epidemiology and health related quality of life (HRQoL) of the new DSM-5 diagnoses, Binge Eating Disorder (BED) and Avoidant/Restrictive Food Intake Disorder (ARFID) in the Australian population. We aimed to investigate the prevalance and burden of these disorders. We conducted two sequential population-based surveys including individuals aged over 15 years who were interviewed in 2014 ( n  = 2732) and 2015 ( n =3005). Demographic information and diagnostic features of DSM-5 eating disorders were asked including the occurrence of regular (at least weekly over the past 3 months) objective binge eating with levels of distress, extreme dietary restriction/fasting for weight/shape control, purging behaviors, overvaluation of shape and/or weight, and the presence of an avoidant/restrictive food intake without overvaluation of shape and/or weight. In 2014 functional impact or role performance was measured with the 'days out of role' question and in 2015, Health Related Quality of Life (HRQoL) was assessed with the Short Form -12 item questionnaire (SF-12v1). The 2014 and 2015 3-month prevalence of eating disorders were: anorexia nervosa-broad 0.4% (95% CI 0.2-0.7) and 0.5% (0.3-0.9); bulimia nervosa 1.1% (0.7-1.5) and 1.2% (0.9-1.7); ARFID 0.3% (0.1-0.5) and 0.3% (0.2-0.6). The 2015 3-month prevalence rates were: BED-broad 1.5% (1.1-2.0); Other Specified Feeding or Eating Disorder (OSFED) 3.2 (2.6-3.9); and Unspecified Feeding or Eating Disorder (UFED) 10.4% (0.9-11.5). Most people with OSFED had atypical anorexia nervosa and majority with UFED were characterised by having recurrent binge eating without marked distress. Eating disorders were represented throughout sociodemographic groups and those with bulimia nervosa and BED-broad had mean weight (BMI, kg/m 2 ) in the obese range. Mental HRQoL was poor in all eating disorder groups but particularly poor for those with BED-broad and ARFID. Individuals with bulimia nervosa, BED

    In Hokkaido and Scandinavia, birch pollen allergic persons are common and they often report oral and pharyngeal hypersensitivity to fruits and vegetables (oral allergy syndrome, OAS), because of immunological cross-reactivity. In Scandinavia, nuts as well as Rosaceae fruits such as apples were the foods most often reported to elicit symptoms. On the other hand, nuts are minor foods causing hypersensitivity in Japan. Even in Japan, regional differences of foods causing hypersensitivity have been reported, which may be related to the regional differences of elementary habit and pollen dispersion. In the present study, we evaluated the intake history of the foods and the frequency of food hypersensitivity in adults from the general population. Three hundreds and thirty nine subjects (20-67 years old) took part in the study. With a questionnaire survey, we asked them about their intake history and hypersensitive symptoms for 33 kinds of fruit, vegetables, and nuts. 30% of subjects had eaten Brazil nuts, 80% had eaten pomegranates, and 81% had eaten hazelnuts. And over 95% of subjects had eaten the other 30 foods. Those who had lived in Hokkaido for more than 20 years had a higher frequency of plum consumption than the others. Those who had lived in Hokkaido for more than 20 years had a lower frequency of loquat, fig and pomegranate consumption than the others. Food hypersensitivity was found in 52 subjects (15.3%). The most common symptom was OAS (46 subjects, 13.6%), and foods most frequently causing OAS were peach (21 subjects, 6.2%), cherry (19 subjects, 5.6%) and apple (17 subjects, 5.0%). 26 subjects (7.7%) reported OAS to Rosaceae fruits. The ratio of having OAS to consuming Rosaceae fruits was 11.0% in the group who had lived in Hokkaido for more than 20 years, which was higher than the group who has lived in Hokkaido for less than 20 years. The intake history of hazelnuts and Brazil nuts was very low, with a correspondingly low frequency of food

    respuesta obtenida para el cociente en el experimento 2 fue debida a la disminución de ambos caracteres componentes. Los resultados de estos experimentos mostraban que los indices no lineales incrementaban cocientes que incluían en el denominador términos cuadráticos o cúbicos. Los índices lineales con restricción para el denominador del cociente eran una alternativa menos eficiente. RÉSUMÉ: Etude expérimentale de l'efficacité relative des indices de sélection non linéares y avec restriction pour des quotients qui comportent des carrés et des cubes Nous avons comparé un index non linéaire de sélection (NL) avec un index linéaire avec restriction (RI) à Tribolium, on utilisant deux expériences de sélection en faveur du quotient poids/(Longueur)(n) . La première expérience fut conçue pour augmenter le poids de la pupe/(Longueur de pupe)(2) , tandis que la deuxième expérience essayait d'améliorer le poids de la larve/(Longueur de larve)(3) . Les caractères de larve et de pupe furent mesurés au bout de 14 et de 21 jours respectivement. Il y avait quatre générations de sélection dans chacune des trois répétitions et la proportion choisie fut celle de 20 %. On prit (m(1) + Ĝ(1) )/(m(2) + Ĝ(2) )(n) come critére de sélection dans les lignes NL, m(1) et m(2) étant les moyennes pour les caractères numérateur et dénominateur, Ĝ(1) et Ĝ(2) les valeurs additives estimées et n étant 2 (expérience 1) ou 3 (expérience 2). Le index avec restriction employé comme critère de sélection dans les lignes RI a été calculé pour augmenter le numérateur et maintenir le dénominateur constant. Les réponses obtenues pour le quotient étaient significativement différentes entre les lignes (P < .05) dans les deux expériences, la réponse plus grande étant celle de la ligne NL. Dans l'expérience 1, la réponse observée dans le numérateur fût significative dans la ligne NL, tandis qu'elle fut positive et significative pour les deux caracteres

  17. Questioning Questions: Elementary Teachers' Adaptations of Investigation Questions Across the Inquiry Continuum

    Science.gov (United States)

    Biggers, Mandy

    2018-02-01

    Questioning is a central practice in science classrooms. However, not every question translates into a "good" science investigation. Questions that drive science investigations can be provided by many sources including the teacher, the curriculum, or the student. The variations in the source of investigation questions were explored in this study. A dataset of 120 elementary science classroom videos and associated lesson plans from 40 elementary teachers (K-5) across 21 elementary school campuses were scored on an instrument measuring the amount of teacher-direction or student-direction of the lessons' investigation questions. Results indicated that the investigation questions were overwhelmingly teacher directed in nature, with no opportunities for students to develop their own questions for investigation. This study has implications for researchers and practitioners alike, calling attention to the teacher-directed nature of investigation questions in existing science curriculum materials, and the need for teacher training in instructional strategies to adapt their existing curriculum materials across the continuum of teacher-directed and student-directed investigation questions. Teachers need strategies for adapting the teacher-directed questions provided in their existing curriculum materials in order to allow students the opportunity to engage in this essential scientific practice.

  18. Children's questions: a mechanism for cognitive development.

    Chouinard, Michael M

    2007-01-01

    Preschoolers' questions may play an important role in cognitive development. When children encounter a problem with their current knowledge state (a gap in their knowledge, some ambiguity they do not know how to resolve, some inconsistency they have detected), asking a question allows them to get targeted information exactly when they need it. This information is available to them when they are particularly receptive to it, and because it comes as the result of their own disequilibrium, it may have depth of processing benefits. In that questions allow children to get information they need to move their knowledge structures closer to adult-like states, the ability to ask questions to gather needed information constitutes an efficient mechanism for cognitive development (referred to in this paper as the Information Requesting Mechanism [IRM]; this term is used because it includes question-asking and other information recruiting behaviors such as gestures, expressions, and vocalizations). However, the role of children's questions in their cognitive development has been largely overlooked. If questions are a force in cognitive development, the following must be true: (1) children must actually ask questions that gather information; (2) children must receive informative answers to their questions if they are able to be of use to cognitive development; (3) children must be motivated to get the information they request, rather than asking questions for other purposes such as attention; (4) the questions children ask must be relevant and of potential use to their cognitive development; (5) we must see evidence that children's questions help them in some way-that is, that they can ask questions for a purpose, and use the information they receive purposefully to successfully achieve some change of knowledge state. This monograph reports data on these points. Study 1 analyzed questions taken from four children's transcripts in the CHILDES database (age 1;2-5;1). This

    Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit-how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes.

  2. Trick questions: cosmopolitan hospitality

    Directory of Open Access Journals (Sweden)

    Eleanor Byrne

    2013-08-01

    Full Text Available Byrne’s paper consists of two parallel texts. The first explores the limits of cosmopolitanism in practice, taking as its subject the Life in the UK Citizenship Test, inaugurated under the Labour Government in 2005. It argues that the test exemplifies the predicament of all attempts at cosmopolitan hospitality as unconditional welcoming, through a discussion of the relation between questioning and welcoming the stranger. Establishing the relationship between cosmopolitanism and hospitality as envisaged in Derrida’s reading of Kant it asks what kind of cosmopolitan hospitality is either possible or desirable by exploring what Derrida calls the ‘perversions’ inherent in the structures of hospitality. It focuses on the concept of the ‘trick questions’ that the state asks the foreigner observed by Derrida in his reading of The Apology of Socrates; questions that seem to invite answers but foreclose the possibilities of a free response. The second text asks how this logic that Derrida identifies can be pushed or coaxed into new ways of addressing the perceived threats of ‘unconditional’ hospitality through a reading of ‘unconditional hospitality’ as queer in the work of Tove Jansson.

    Full Text Available Ankylosing spondylitis is a chronic inflammatory disease that affects the synovial membrane, joint entheses and para-articular structures of the spine, including the sacroiliac joints and limbs. We present a case of ankylosing spondylitis that had evolved for 12 years despite the relatively early diagnosis and treatment, showing flexion deformity and limitation of spinal movements. On radiological examination an early evolution to ankylosis was observed, which motivated us to make a reflection and a question.

  7. Biology Question Generation from a Semantic Network

    Science.gov (United States)

    Zhang, Lishan

    Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own questions. In order to supply instructors with biology questions, a semantic network approach was developed for generating open response biology questions. The generated questions were compared to professional authorized questions. To boost students' learning experience, adaptive selection was built on the generated questions. Bayesian Knowledge Tracing was used as embedded assessment of the student's current competence so that a suitable question could be selected based on the student's previous performance. A between-subjects experiment with 42 participants was performed, where half of the participants studied with adaptive selected questions and the rest studied with mal-adaptive order of questions. Both groups significantly improved their test scores, and the participants in adaptive group registered larger learning gains than participants in the control group. To explore the possibility of generating rich instructional feedback for machine-generated questions, a question-paragraph mapping task was identified. Given a set of questions and a list of paragraphs for a textbook, the goal of the task was to map the related paragraphs to each question. An algorithm was developed whose performance was comparable to human annotators. A multiple-choice question with high quality distractors (incorrect answers) can be pedagogically valuable as well as being much easier to grade than open-response questions. Thus, an algorithm was developed to generate good distractors for multiple-choice questions. The machine-generated multiple-choice questions were compared to human-generated questions in terms of three measures: question difficulty, question discrimination and distractor usefulness. By recruiting 200 participants from

  3. Repetitive Questioning II

    Directory of Open Access Journals (Sweden)

    R. C. Hamdy MD

    2018-02-01

    Full Text Available Repetitive questioning is a major problem for caregivers, particularly taxing if they are unable to recognize and understand the reasons why their loved one keeps asking the same question over and over again. Caregivers may be tempted to believe that the patient does not even try to remember the answer given or is just getting obnoxious. This is incorrect. Repetitive questioning is due to the underlying disease: The patient’s short term memory is impaired and he is unable to register, encode, retain and retrieve the answer. If he is concerned about a particular topic, he will keep asking the same question over and over again. To the patient each time she asks the question, it is as if she asked it for the first time. Just answering repetitive questioning by providing repeatedly the same answer is not sufficient. Caregivers should try to identify the underlying cause for this repetitive questioning. In an earlier case study, the patient was concerned about her and her family’s safety and kept asking whether the doors are locked. In this present case study, the patient does not know how to handle the awkward situation he finds himself in. He just does not know what to do. He is not able to adjust to the new unexpected situation. So he repeatedly wants to reassure himself that he is not intruding by asking the same question over and over again. We discuss how the patient’s son-in-law could have avoided this situation and averted the catastrophic ending.

    There is a widespread sentiment that panspermia is uninteresting is because it does not answer fundamental questions about the origin of life. The strongest version of panspermia asks entirely new questions. While barriers to the acceptance of panspermia are falling and evidence supporting it is accumulating, the mere possibility of panspermia unhinges the Darwinian account of evolutionary progress. The new theory removes an issue dividing science and religion, but it requires an amendment to the big bang theory.

    2011-01-01

    Abstract Objective  To combine insights from multiple disciplines into a set of questions that can be used to investigate contextual factors affecting health decision making. Background  Decision‐making processes and outcomes may be shaped by a range of non‐medical or ‘contextual’ factors particular to an individual including social, economic, political, geographical and institutional conditions. Research concerning contextual factors occurs across many disciplines and theoretical domains, but few conceptual tools have attempted to integrate and translate this wide‐ranging research for health decision‐making purposes. Methods  To formulate this tool we employed an iterative, collaborative process of scenario development and question generation. Five hypothetical health decision‐making scenarios (preventative, screening, curative, supportive and palliative) were developed and used to generate a set of exploratory questions that aim to highlight potential contextual factors across a range of health decisions. Findings  We present an exploratory tool consisting of questions organized into four thematic domains – Bodies, Technologies, Place and Work (BTPW) – articulating wide‐ranging contextual factors relevant to health decision making. The BTPW tool encompasses health‐related scholarship and research from a range of disciplines pertinent to health decision making, and identifies concrete points of intersection between its four thematic domains. Examples of the practical application of the questions are also provided. Conclusions  These exploratory questions provide an interdisciplinary toolkit for identifying the complex contextual factors affecting decision making. The set of questions comprised by the BTPW tool may be applied wholly or partially in the context of clinical practice, policy development and health‐related research. PMID:21029277

    2015-01-01

    Orthographic and grammatical errors are a common feature of informal texts written by lay people. Health-related questions asked by consumers are a case in point. Automatic interpretation of consumer health questions is hampered by such errors. In this paper, we propose a method that combines techniques based on edit distance and frequency counts with a contextual similarity-based method for detecting and correcting orthographic errors, including misspellings, word breaks, and punctuation errors. We evaluate our method on a set of spell-corrected questions extracted from the NLM collection of consumer health questions. Our method achieves a F1 score of 0.61, compared to an informed baseline of 0.29, achieved using ESpell, a spelling correction system developed for biomedical queries. Our results show that orthographic similarity is most relevant in spelling error correction in consumer health questions and that frequency and contextual information are complementary to orthographic features.

    Nursing handovers are an important component of patient safety and quality in communicating across transitions of care. To determine the functions and roles of questions in nursing handovers, and of how questions contribute to handover quality improvement in specialty settings of an Australian tertiary hospital. An ethnographic research design was employed. Participant observations were conducted which were audiorecorded and transcribed. Question-response sequences and the roles of questions in the handovers were coded. Questions served many functions, and included: requests for information, requests for confirmation, other initiations of repair, outloud utterances, understanding checks, requests for action and agreement, and knowledge checks. Questioning was mostly used to transmit patient-related information, and nurses could use questioning to jointly construct understandings about patients. Future research should examine how questions function in diverse clinical environments, such as rural and regional hospitals, and how questioning occurs in multidisciplinary handover situations.

  10. Grant recipients' rights in question.

    1984-01-01

    Although organizations that provide privately funded abortions or abortion referral and counseling are engaging in constitutionally protected activities, opponents of legal abortion are seeking to deny eligibility for federal family planning funding to them. The issue of the rights of organizations receiving federal funds has been simmering for several years, but in 1984 the US Congress must renew the key federal funding authorization for domestic and international family planning services. The question is an abortion issue but a much larger issue as well, involving the limits of the conditions any government agency can put on activities of organizations it helps to fund. Political activity regarding the question has increased, and includes attempts by 4 states to block award of state family planning funds to organizations using private funds for abortion activities, passage of the Adolescent Family Act which permits funding only to programs that do not advocate abortion, attempts to add antiabortion amendments to the Foreign Assistance Act, termination of US Agency for International Development (AID) funding of the scientific journal International Family Planning Perspectives because it reported the findings of research on the health consequences of illegal abortions, attempts to block USAID funds to the Pathfinder Fund because it used nonfederal funds for abortion-related services, and attempts to exclude the Planned Parenthood Federation of America from the annual Combined Federal Campaign, the federal employee's charitable contributions drive. If new restrictions on government funding of family planning organizations become law in 1984, they could undermine the US commitment to family planning. Only 74 of the 5000 US family planning clinics receiving Title X family planning funds perform abortions, and they use state or private funds. Efforts to block Title X funding to agencies involved in abortion would run counter to the laws and policies of 15 states that

  11. Nuclear power: the question of public acceptance

    International Nuclear Information System (INIS)

    Otway, H.J.; Maurer, D.; Thomas, K.

    1978-01-01

    Technologists have been surprised - in view of the persuasive technical arguments - at the strength of public opposition to nuclear power. But their assumption that information and argument can, by their rational force, change public opinion on sensitive issues, rests on oversimplified theories about attitude formation. When the grounds for opposition to or approval of a controversial programme are investigated - as the authors of this article have done, on the issue of nuclear power - it becomes apparent that attitude formation is not, in the technologists' sense, a 'rational' process. Here the authors describe an attitude model, and present the results of its application to the question of public attitudes to nuclear power - including the discovery of the relatively minor role that technical and environmental questions play in determining those attitudes.

    The aim is to understand the experience of being cared for in psychiatric care as a patient and as a parent. Parenthood represents the natural form of human caring, a human directedness regardless of gender. The study has its starting point in this image, as it applies to mothers who receive care as provided in a psychiatric care context. The theoretical perspective is the theory of caritative caring, and the methodological approach is the philosophical hermeneutics outlined by Gadamer. The sample was purposeful: 10 mothers who experienced being a mother while suffering from mental illness and receiving care from professionals in psychiatric specialist health care contexts. The interpretation process is inductive, deductive, and abductive, and includes different levels of rational, contextual, existential, and ontological interpretation supported by the chosen theoretical perspective and the philosophy of ethics outlined by Emmanuel Levinas. The interpretation on the contextual level shows that the patients do not talk about their inner feelings concerning themselves as mothers in the care relationship. The interpretation on the existential level reveals the meaning of the mothers' experiences of inner struggle between their inner demands and assuming a mask of silence. The patients' experiences on the ontological level were interpreted as a struggle between the responsibility inherent in human being and the fear of condemnation. At the ontological level, a new hypothesis of the understanding of the meaning of the parents' experiences was formulated: Being in care as a patient and as a parent means struggling to restore one's responsibility as a human being. This new understanding paves the way for caring of the patient who is a parent.

  1. Questions about elastic waves

    CERN Document Server

    Engelbrecht, Jüri

    2015-01-01

    This book addresses the modelling of mechanical waves by asking the right questions about them and trying to find suitable answers. The questions follow the analytical sequence from elementary understandings to complicated cases, following a step-by-step path towards increased knowledge. The focus is on waves in elastic solids, although some examples also concern non-conservative cases for the sake of completeness. Special attention is paid to the understanding of the influence of microstructure, nonlinearity and internal variables in continua. With the help of many mathematical models for describing waves, physical phenomena concerning wave dispersion, nonlinear effects, emergence of solitary waves, scales and hierarchies of waves as well as the governing physical parameters are analysed. Also, the energy balance in waves and non-conservative models with energy influx are discussed. Finally, all answers are interwoven into the canvas of complexity.

    Advances in RHD genotyping offer an opportunity to update policies and practices for testing weak D phenotypes and administration of Rh immune globulin to postpartum women. To repeat questions from a 1999 College of American Pathologists proficiency test survey, to evaluate current practices for testing for weak D and administration of Rh immune globulin, and to determine whether there is an opportunity to begin integrating RHD genotyping in laboratory practice. The College of American Pathologists Transfusion Medicine Resource Committee sent questions from the 1999 survey to laboratories that participated in the 2012 proficiency test survey. The results of the 2012 survey were compared with those from 1999. Results from published RHD genotyping studies were analyzed to determine if RHD genotyping could improve current policies and practices for serological Rh typing. More than 3100 survey participants responded to the 2012 questions. The most significant finding was a decrease in the number of transfusion services performing a serological weak D test on patients as a strategy to manage those with a weak D as Rh negative (from 58.2% to 19.8%, P policies and practices could improve the accuracy of Rh typing results, reduce unnecessary administration of Rh immune globulin in women with a weak D, and decrease transfusion of Rh-negative red blood cells in most recipients with a serological weak D phenotype.

  7. Expressions For Total Energy And Relativistic Kinetic Energy At Low Speeds In Special Relativity Must Include Rotational And Vibrational As Well As Linear Kinetic Energies

    Science.gov (United States)

    Brekke, Stewart

    2017-09-01

    Einstein calculated the total energy at low speeds in the Special Theory of Relativity to be Etotal =m0c2 + 1 / 2m0v2 . However, the total energy must include the rotational and vibrational kinetic energies as well as the linear kinetic energies. If 1 / 2 Iω2 is the expression for the rotational kinetic energy of mass and 1 / 2 kx02 is the vibrational kinetic energy expression of a typical mass, the expression for the total energy of a mass at low speeds must be Etotal =m0c2 + 1 / 2m0v2 + 1 / 2 Iω2 + 1 / 2 kx02 . If this expression is correct, the relativistic kinetic energy of a mass. at low speeds must include the rotational and vibrational kinetic energies as well as the linear kinetic energies since according to Einstein K = (m -m0) c2 and therefore, K = 1 / 2m0v2 + 1 / 2 Iω2 + 1 / 2 kx02 .

    The food habit is involved in the onset and development of lifestyle-related diseases. In this review I would like to describe a historical case of vitamin B1 deficiency, as well as our case study of fatty acid metabolism abnormality due to carnitine deficiency. In history, the army and navy personnel in Japan at the end of the 19th century received food rations based on a high-carbohydrate diet including white rice, resulting in the onset of beriberi. An epidemiological study by Kenkan Takaki revealed the relationship between the onset of beriberi and rice intake. Then, Takaki was successful in preventing the onset of beriberi by changing the diet. However, the primary cause had yet to be elucidated. Finally, Christian Eijkman established an animal model of beriberi (chickens) showing peripheral neuropathy, and he identified the existence of an anti-beriberi substance, vitamin B1. This is an example of the successful control of a disease by integrating the results of epidemiological and experimental studies. In our study using a murine model of fatty acid metabolism abnormality caused by carnitine deficiency, cardiac abnormality and fatty liver developed depending on the amount of dietary fat. In addition, the mice showed disturbance of orexin neuron activity related to the sleep-arousal system, which is involved in fatigue symptoms under fasting condition, one of the states showing enhanced fatty acid metabolism. These findings suggest that fatty acid toxicity is enhanced when the mice are more dependent on fatty acid metabolism. Almost simultaneously, a human epidemiological study showed that narcolepsy, which is caused by orexin system abnormality, is associated with the polymorphism of the gene coding for carnitine palmitoyltransferase 1B, which is involved in carnitine metabolism. To understand the pathological mechanism of fatty acid toxicity, not only an experimental approach using animal models, but also an epidemiological approach is necessary. The

    Purpose: This study analyzed functioning and symptom scores for longitudinal quality of life (QoL) from patients with locally advanced cervical cancer who underwent definitive chemoradiation therapy with image guided adaptive brachytherapy in the EMBRACE study. Methods and Materials: In total, 744 patients at a median follow-up of 21 months were included. QoL was prospectively assessed using European Organization for Research and Treatment of Cancer Quality of Life core module 30 (EORTC QLQ-C30) and EORTC cervical cancer module 24 (CX24) questionnaires at baseline, then every 3 months during the first year, every 6 months in the second and third years, and finally yearly thereafter in patients with no evidence of disease. Outcomes were evaluated over time and compared to those from an age-matched female reference population. Results: General QoL and emotional and social functioning were impaired at baseline but improved during the first 6 months after treatment, to reach a level comparable to that of the reference population, whereas cognitive functioning remained impaired. Both social and role functioning showed the lowest scores at baseline but which increased after treatment to reach a plateau at 6 months and then declined slightly at 3 and 4 years. The overall symptom experience was elevated at baseline and decreased to a level within the range of that of the reference population. Similarly, tumor-related symptoms (eg, pain, appetite loss, and constipation), which were present before treatment, decreased substantially at the first follow-up after treatment. Several treatment-related symptoms developed either immediately after and persisted over time (diarrhea, menopausal symptoms, peripheral neuropathy, and sexual functioning problems) or developed gradually after treatment (lymphedema and dyspnea). Conclusions: This longitudinal prospective QoL analysis showed that patients' general QoL and functioning were impaired before treatment compared to

    What are the effects of weight management interventions that include a diet component on weight-related outcomes in pregnant and postpartum women?The primary objective of this systematic review is to evaluate the effectiveness of weight management interventions which include a diet component and are aimed at limiting gestational weight gain and postpartum weight retention in women.The second objective of this systematic review is to investigate included intervention components with respect to effect on weight-related outcomes. This may include, but is not limited to: length of intervention, use of face-to-face counselling, group or individual consultations, use of other interventions components including exercise, use of goals and use of support tools like food diaries, coaching, including email or text message support. Around half of all women of reproductive age are either overweight or obese, with women aged 25-34 years having a greater risk of substantial weight gain compared with men of all ages. Excessive gestational weight gain (GWG) and postpartum weight retention (PPWR) may play a significant role in long term obesity. Having one child doubles the five- and 10-year obesity incidence for women, with many women who gain excessive weight during pregnancy remaining obese permanently. Excessive GWG and/or PPWR can also significantly contribute to short- and long-term adverse health outcomes for mother, baby and future pregnancies.Maternal obesity increases the risk of pregnancy related complications such as pre-eclampsia, gestational diabetes mellitus, stillbirth and the rate of caesarean section. Childhood obesity is a further long term complication of maternal obesity for offspring, which may persist in to adulthood. Excess GWG is also a risk factor for PPWR both in the short and long-term. Nehring et al. conducted a meta-analysis with over 65,000 women showing that, compared to women who gained weight within recommendations during pregnancy, women with GWG

    Nanomedicine will play an increasing role in prevention and treatment across the entire healthcare spectrum. However, their precise market size, economic value and areas of application remain unclear. This opacity, including the question of what constitutes nanomedicine matters, especially when considered alongside the key regulatory questions and concerns. This article begins by placing these key questions into context in relation to the current scientific state of the art, focusing particular attention on the human health and safety context. In exploring these central questions surrounding the regulation of nanomedicine, this perspective also explores existing and suggested frameworks that aim to deal with emerging technologies more generally. It then outlines priority areas for action and general conclusions specific to nanomedicine.

    The DAG has become involved with the topics and problems of energy policy very early and has already pointed on the necessity of an overall plan for energy policy for the Federal Republic of Germany in the sixties. The claim directed to the legislative bodies in the F. R. of Germany had sprung from the conclusion that endangering energy supply in the medium or long term would lead to a serious disorder within economic and thus social life. In order to meet the risks for industry and society which are related to an endangering of energy supply at an early stage and with regard to the future the DAG think it indispensable to further update the existing political energy programme of the Federal Government. The DAG hope that the political claims which are included in this brochure and which were worked out at the 8th Energiepolitische Bundestagung of the DAG might influence the German programme for energy policy. At the same time this brochure is meant to provide a factual contribution to the present energy discussion which, in general, is still based on emotional arguments. (orig./UA) [de

    Full Text Available In order to analyze functional connectivity in untreated and treated patients with schizophrenia, resting-state fMRI data were obtained for whole-brain functional connectivity analysis from 22 first-episode neuroleptic-naïve schizophrenia (NNS, 61 first-episode neuroleptic-treated schizophrenia (NTS patients, and 60 healthy controls (HC. Reductions were found in untreated and treated patients in the functional connectivity between the posterior cingulate gyrus and precuneus, and this was correlated with the reduction in volition from the Positive and Negative Symptoms Scale (PANSS, that is in the willful initiation, sustenance, and control of thoughts, behavior, movements, and speech, and with the general and negative symptoms. In addition in both patient groups interhemispheric functional connectivity was weaker between the orbitofrontal cortex, amygdala and temporal pole. These functional connectivity changes and the related symptoms were not treated by the neuroleptics. Differences between the patient groups were that there were more strong functional connectivity links in the NNS patients (including in hippocampal, frontal, and striatal circuits than in the NTS patients. These findings with a whole brain analysis in untreated and treated patients with schizophrenia provide evidence on some of the brain regions implicated in the volitional, other general, and negative symptoms, of schizophrenia that are not treated by neuroleptics so have implications for the development of other treatments; and provide evidence on some brain systems in which neuroleptics do alter the functional connectivity.

Considered some time ago as the perfect clean substitute to petroleum, biofuels are now suspected to have harmful effects on the environment. Should it be just an enormous technical, environmental and human swindle? Should we abandon immediately biofuels to protect the earth and fight the threatening again starvation? Should we wait for the second generation of efficient biofuels, made from non food-derived products and cultivation wastes? This book analyses this delicate debate through 5 main questions: do they starve the world? Are they a clean energy source? Do they contribute to deforestation? Are they economically practicable? Is the second generation ready? (J.S.)

    Full Text Available This study investigated students’ preference on teacher’s questions and questionings techniques and more importantly on how they could facilitate or impede their learning. The results on teacher’s questioning techniques showed that random nomination was more preferred than pre-arranged format nomination. In addition, techniques of nominating volunteering students and of giving wait-time were disliked by most student-respondents. As for types of question, the yes/no question was favored by most of the respondents. Different from the yes/no question, the number of respondents leaning forward to the analysis question, questions about fact of life, and questions to state opinion did not show a significant difference from the number of those leaning against the same questions.

  6. Questioning As a Pedagogical Tool for Eliciting Student Generated Questions During the Teaching of Acid-base Equilibria

    Directory of Open Access Journals (Sweden)

    Ayoade Ejiwale Okanlawon

    2012-04-01

    Full Text Available Traditionally, teachers simply taught problem-solving by explaining the worked-out examples taken from textbooks and students were expected to listen quietly, copy the solution to the problem, and then work independently at their desks. But a large body of research notes that guiding students to develop a solution pathway with questioning is more effective than simply explaining the sequence of steps to solve the problem. Students involved in question- and-answer sessions are more attentive than those who listen passively to teacher explanations and they are more likely to generate questions. The questions students ask during a lesson perform a number of important functions, including providing the teacher with valuable information about students’ understanding and misunderstanding, fostering self-regulation, inviting classroom discussions and aiding comprehension of contents presented. The skill of posing questions during classroom instruction is often under-valued and under taught in today’s classrooms. To encourage students to ask quality and thought provoking questions related to the contents taught, explicit instruction is required. This paper, therefore, qualitatively reports factors that foster student generated questions during the problem-solving instruction involving acid-base titration problem.

    Early initiation of basic resuscitation interventions within 60 s in apneic newborn infants is thought to be essential in preventing progression to circulatory collapse based on experimental cardio-respiratory responses to asphyxia. The objectives were to describe normal transitional respiratory adaption at birth and to assess the importance of initiating basic resuscitation within the first minutes after birth as it relates to neonatal outcome. This is an observational study of neonatal respiratory adaptation at birth in a rural hospital in Tanzania. Research assistants (n=14) monitored every newborn infant delivery and the response of birth attendants to a depressed baby. Time to initiation of spontaneous respirations or time to onset of breathing following stimulation/suctioning, or face mask ventilation (FMV) in apneic infants, and duration of FMV were recorded. 5845 infants were born; 5689 were liveborn, among these 4769(84%) initiated spontaneous respirations; 93% in ≤30 s and 99% in ≤60 s. Basic resuscitation (stimulation, suction, and/or FMV) was attempted in 920/5689(16.0%); of these 459(49.9%) received FMV. Outcomes included normal n=5613(96.0%), neonatal deaths n=56(1.0%), admitted neonatal area n=20(0.3%), and stillbirths n=156(2.7%). The risk for death or prolonged admission increases 16% for every 30 s delay in initiating FMV up to six minutes (p=0.045) and 6% for every minute of applied FMV (p=0.001). The majority of lifeless babies were in primary apnea and responded to stimulation/suctioning and/or FMV. Infants who required FMV were more likely to die particularly when ventilation was delayed or prolonged. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Roberts, Kirk; Demner-Fushman, Dina

    2016-05-01

    This paper discusses the creation of a semantically annotated corpus of questions about patient data in electronic health records (EHRs). The goal is to provide the training data necessary for semantic parsers to automatically convert EHR questions into a structured query. A layered annotation strategy is used which mirrors a typical natural language processing (NLP) pipeline. First, questions are syntactically analyzed to identify multi-part questions. Second, medical concepts are recognized and normalized to a clinical ontology. Finally, logical forms are created using a lambda calculus representation. We use a corpus of 446 questions asking for patient-specific information. From these, 468 specific questions are found containing 259 unique medical concepts and requiring 53 unique predicates to represent the logical forms. We further present detailed characteristics of the corpus, including inter-annotator agreement results, and describe the challenges automatic NLP systems will face on this task.

    Consumers increasingly use online resources for their health information needs. While current search engines can address these needs to some extent, they generally do not take into account that most health information needs are complex and can only fully be expressed in natural language. Consumer health question answering (QA) systems aim to fill this gap. A major challenge in developing consumer health QA systems is extracting relevant semantic content from the natural language questions (question understanding). To develop effective question understanding tools, question corpora semantically annotated for relevant question elements are needed. In this paper, we present a two-part consumer health question corpus annotated with several semantic categories: named entities, question triggers/types, question frames, and question topic. The first part (CHQA-email) consists of relatively long email requests received by the U.S. National Library of Medicine (NLM) customer service, while the second part (CHQA-web) consists of shorter questions posed to MedlinePlus search engine as queries. Each question has been annotated by two annotators. The annotation methodology is largely the same between the two parts of the corpus; however, we also explain and justify the differences between them. Additionally, we provide information about corpus characteristics, inter-annotator agreement, and our attempts to measure annotation confidence in the absence of adjudication of annotations. The resulting corpus consists of 2614 questions (CHQA-email: 1740, CHQA-web: 874). Problems are the most frequent named entities, while treatment and general information questions are the most common question types. Inter-annotator agreement was generally modest: question types and topics yielded highest agreement, while the agreement for more complex frame annotations was lower. Agreement in CHQA-web was consistently higher than that in CHQA-email. Pairwise inter-annotator agreement proved most

  12. Towards the resolution of a long-standing evolutionary question: muscle identity and attachments are mainly related to topological position and not to primordium or homeotic identity of digits.

    Signaling for limb bone development usually precedes that for muscle development, such that cartilage is generally present before muscle formation. It remains obscure, however, if: (i) tetrapods share a general, predictable spatial correlation between bones and muscles; and, if that is the case, if (ii) such a correlation would reflect an obligatory association between the signaling involved in skeletal and muscle morphogenesis. We address these issues here by using the results of a multidisciplinary analysis of the appendicular muscles of all major tetrapod groups integrating dissections, muscle antibody stainings, regenerative and ontogenetic analyses of fluorescently-labeled (GFP) animals, and studies of non-pentadactyl human limbs related to birth defects. Our synthesis suggests that there is a consistent, surprising anatomical pattern in both normal and abnormal phenotypes, in which the identity and attachments of distal limb muscles are mainly related to the topological position, and not to the developmental primordium (anlage) or even the homeotic identity, of the digits to which they are attached. This synthesis is therefore a starting point towards the resolution of a centuries-old question raised by authors such as Owen about the specific associations between limb bones and muscles. This question has crucial implications for evolutionary and developmental biology, and for human medicine because non-pentadactyly is the most common birth defect in human limbs. In particular, this synthesis paves the way for future developmental experimental and mechanistic studies, which are needed to clarify the processes that may be involved in the elaboration of the anatomical patterns described here, and to specifically test the hypothesis that distal limb muscle identity/attachment is mainly related to digit topology. © 2015 Anatomical Society.

    Today, energy in the center of the world events. People get swamped with information about energy, environment, energy saving or renewable energy sources. However, the solutions proposed are still in the centre of debates and no consensus exists which allows to define a clear policy: nuclear energy or wind power? Solar energy or biomass fuels? And what about the meaning of the expression 'clean coal'? And why oil prices go up and down while it is said that the resource is close to exhaustion? Mass media are trying to tell us that 'urgency is here', mainly because of the climatic threat of greenhouse gases and because of a world economy totally dependent of politically unstable areas, like Middle East, Africa or Caucasus, but with huge oil and gas resources. And what about Europe, and what about all this gas in Russia? It is hard for a non-specialist to find his way in this complex domain. This is the aim of this book which has opted for the non-politically correct attitude to answer 101 key-questions about the energy topic: Europe's security of supply, energy geopolitics, oil future, energy crises, sustainable development etc. (J.S.)

    Full Text Available Is legal history a left-over or is it waiting for a takeover bid (just like a company in serious trouble which would allow the expression of new analyses and outlines for a better understanding of the contemporary western world? Its propositions of erudition, are they just interesting for small academic circles, or could they open a new pathway for fundamental reflections on the phenomenon of norms in general and the structure of its evolution in the special case of norm-production coming from Roman Christianity? And what is the significance of the idea of »legal tradition«, an idea forged in Western Europe, within the framework of a presumed global westernization without any counter-balance? The essay discusses the illegibility of legal history in today’s culture. Under the well reflected motto »The Forbidden Question« it concludes firmly: To renovate itself, this discipline has to perform its work in a new way, guided by a very precise and distinct vision on theory. The author examines the conditions for this.

  16. Cosmic questions: an introduction.

    Primack, J R; Abrams, N E

    2001-12-01

    This introductory talk at the Cosmic Questions conference sponsored by the AAAS summarizes some earlier pictures of the universe and some pictures based on modern physics and cosmology. The uroboros (snake swallowing its tail) is an example of a traditional picture. The Biblical flat-earth picture was very different from the Greek spherical earth-centered picture, which was the standard view until the end of the Middle Ages. Many people incorrectly assume that the Newtonian picture of stars scattered through otherwise empty space is still the prevailing view. Seeing Earth from space shows the power of a new picture. The Hubble Space Telescope can see all the bright galaxies, all the way to the cosmic Dark Ages. We are at the center of cosmic spheres of time: looking outward is looking backward in time. All the matter and energy in the universe can be represented as a cosmic density pyramid. The laws of physics only allow the material objects in the universe to occupy a wedge-shaped region on a diagram of mass versus size. All sizes--from the smallest size scale, the Planck scale, to the entire visible universe--can be represented on the Cosmic Uroboros. There are interesting connections across this diagram, and the human scale lies in the middle.

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction . On the one ...

    A Question of Authority. This article deals with a certain scenario and several reviewers are to give their opinion. This one is in regards to - Suspending an IACUC approved animal use activity is about the last thing a research institution wants to do. Consider the predicament that the Great Eastern University IACUC faced when Dr. Janet Jenkins, the Attending Veterinarian, suspended all animal use activity on an approved protocol of Dr. Roy Maslo. Jenkins had the IACUCs authority to temporarily suspend a protocol, subject to review by a quorum of the full committee. She alleged that Maslo used mice from his breeding colony, not purchased rats, to begin a new study. Jenkins saw Maslos technicians bringing mouse cages to a procedure room and setting up for a minor survival surgery. She asked them to wait until she clarified things as she felt confident that the protocol called for rats. She called Maslo and asked him if the study had been approved for mice, to which he responded affirmatively. Still not feeling quite assured, she went to her office, reviewed the protocol, and found only rat studies described. She also called the IACUC office to see if there were any approved amendments which she may not have received, and was told that there were none. By the time she returned, one procedure was completed. Understandably upset, she informed the technicians and Maslo that any further activity on the protocol was suspended until the issue was resolved. Jenkins informed the IACUC chairman who in turned called an emergency meeting of the committee.

    Full Text Available The objective of the study is to determine the level of the reasoning skills of the secondary school students. This research has been conducted during the academic year of 2015-2016 with the participation of 51 students in total, from a province in the Black Sea region of Turkey by using random sampling method. Case study method has been used in this study, since it explains an existing situation. In this study, content analysis from the qualitative research methods was carried out. In order to ensure the validity of the scope, agreement percentage formula was used and expert opinions were sought.The problem named Holiday from the Chapter 1 of the normal units in Problem Solving Questions from PISA (Program for International Student Assessments [35] are used as the data collection tool for the study. The problem named Holiday consists of two questions. Applied problems were evaluated according to the mathematical reasoning stages of TIMSS (2003. The findings suggest that the students use proportional reasoning while solving the problems and use the geometric shapes to facilitate the solution of the problem. When they come across problems related to each other, it is observed that they create connections between the problems based on the results of the previous problem. In conclusion, the students perform crosscheck to ensure that their solutions to the problems are accurate.

  11. Les questions de migrations internationales

    Science.gov (United States)

    Samman, Mouna Liliane

    1993-03-01

    International migrations have growing implications for both countries of origin and countries of destination. In the latter, the presence of foreigners and of members of their families today creates problems of integration, causes argument and brings mounting xenophobia. Paralleling political, economic and social measures taken by public authorities to respond to these difficulties, education needs to assist in defusing the resulting social tensions by preparing the minds of learners and helping to develop new attitudes. In particular, when educational programmes address questions of international migration, these should be treated in the framework of historical evolution so that their real significance and their true temporal and spatial dimensions become apparent. It is also important that the growing interdependence between countries should be made plain, that national history should be placed in its international context, and that the true consequences of these developments should be made clear. In this context, learners need to be acquainted with Human Rights, thereby stressing universal moral values and the role of the individual. Lastly, questions relating to international migration are usually presented in the media in a selective and partial manner, and the young people who take in this information often accept the hasty judgments which are made of situations as proven facts. This is why all teaching about international migration needs to be considered or reconsidered in the light of the complementary or competing actions of the media.

    2016-01-01

    We submit that interaction patterns within healthcare teams should be more comprehensively explored during debriefings in simulation-based training because of their importance for clinical performance. We describe how circular questions can be used for that purpose. Circular questions are based on social constructivism. They include a variety of systemic interviewing methods. The goals of circular questions are to explore the mutual dependency of team members' behavior and recurrent behavior patterns, to generate information, to foster perspective taking, to "fluidize" problems, and to put actions into relational contexts. We describe the nature of circular questions, the benefits they offer, and ways of applying them during debriefings.

    To establish an accurate and comprehensive injury incidence registry of all rugby union-related catastrophic events in South Africa between 2008 and 2011. An additional aim was to investigate correlates associated with these injuries. Prospective. The South African amateur and professional rugby-playing population. An estimated 529 483 Junior and 121 663 Senior rugby union ('rugby') players (population at risk). Annual average incidences of rugby-related catastrophic injuries by type (cardiac events, traumatic brain and acute spinal cord injuries (ASCIs)) and outcome (full recoveries-fatalities). Playing level (junior and senior levels), position and event (phase of play) were also assessed. The average annual incidence of ASCIs and Traumatic Brain Injuries combined was 2.00 per 100 000 players (95% CI 0.91 to 3.08) from 2008 to 2011. The incidence of ASCIs with permanent outcomes was significantly higher at the Senior level (4.52 per 100 000 players, 95% CI 0.74 to 8.30) than the Junior level (0.24 per 100 000 players, 95% CI 0 to 0.65) during this period. The hooker position was associated with 46% (n=12 of 26) of all permanent ASCI outcomes, the majority of which (83%) occurred during the scrum phase of play. The incidence of rugby-related catastrophic injuries in South Africa between 2008 and 2011 is comparable to that of other countries and to most other collision sports. The higher incidence rate of permanent ASCIs at the Senior level could be related to the different law variations or characteristics (eg, less regular training) compared with the Junior level. The hooker and scrum were associated with high proportions of permanent ASCIs. The BokSmart injury prevention programme should focus efforts on these areas (Senior level, hooker and scrum) and use this study as a reference point for the evaluation of the effectiveness of the programme.

    2014-08-01

    In the health field, technologies of care relations are in the scope of the worker-user encounter, implying intersubjectivity with the development of relationships between subjects, resulting in action. Evaluation studies synthesize knowledge produced on the consequences of using these technologies for society. This anthropological study aims to understand the perception of the elderly regarding the resolution capability and effectiveness of the acts produced in health care relationships in the context of the Family Health Strategy (ESF). The group studied consisted of 57 elderly residents in Bambui, State of Minas Gerais, Brazil. The model of signs, meanings and actions was used for collecting and analyzing data and the semi-structured interview was applied as a research technique. Elderly individuals assess resolution capability and effectiveness of the acts of care in the ESF as negative, with relation to the quality of user and professional interaction. The ESF is not effective and the desired change in the health care model has not occurred in practice. It repeats the centrality of the medical-drug-procedure model that treats the disease rather than the patient, perceiving old age as a disease and illness as being related to aging.

    Potash is mined worldwide to provide potassium, an essential nutrient for food crops. Evaporite-hosted potash deposits are the largest source of salts that contain potassium in water-soluble form, including potassium chloride, potassium-magnesium chloride, potassium sulfate, and potassium nitrate. Thick sections of evaporitic salt that form laterally continuous strata in sedimentary evaporite basins are the most common host for stratabound and halokinetic potash-bearing salt deposits. Potash-bearing basins may host tens of millions to more than 100 billion metric tons of potassium oxide (K2O). Examples of these deposits include those in the Elk Point Basin in Canada, the Pripyat Basin in Belarus, the Solikamsk Basin in Russia, and the Zechstein Basin in Germany.

    Astronomy is not only a branch of science but also an important part of the culture and civilisations of peoples. Starting with archeoastronomy to the present day, it has always contributed to a better understanding of life, of humanity. After 400 years of modern astronomy, it still addresses major problems such as: Why there is something rather than nothing? Why is nature comprehensible to humans? How is cosmos related to humanity? Do multiverses exist? Is there life on other planets? Are we alone in the universe? Does the universe have a beginning? If so, what does it mean? How did the universe originate? All these questions are a challenge for interdisciplinary and transdisciplinary investigations, for philosophers, physicists, cosmologists, mathematicians, theologians. The new insights gained by pursuing in depth these common investigations will shape the society we live in and have important consequences on the future we are creating.

    In this paper we raise 'ten questions' broadly related to 'omics', the term systems biology, and why the new biology has failed to deliver major therapeutic advances for many common diseases, especially diabetes and cardiovascular disease. We argue that a fundamentally narrow and reductionist...... perspective about the contribution of genes and genetic variants to disease is a key reason 'omics' has failed to deliver the anticipated breakthroughs. We then point out the critical utility of key concepts from physiology like homeostasis, regulated systems and redundancy as major intellectual tools...... common diseases. Finally, we attempt to integrate our critique of reductionism into a broader social framework about so-called translational research in specific and the root causes of common diseases in general. Throughout we offer ideas and suggestions that might be incorporated into the current...

    Several projects aimed at identifying priority issues for conservation with high relevance to policy have recently been completed in several countries. Two major types of projects have been undertaken, aimed at identifying (i) policy-relevant questions most imperative to conservation and (ii) horizon scanning topics, defined as emerging issues that are expected to have substantial implications for biodiversity conservation and policy in the future. Here, we provide the first overview of the outcomes of biodiversity and conservation-oriented projects recently completed around the world using this framework. We also include the results of the first questions and horizon scanning project completed for a Mediterranean country. Overall, the outcomes of the different projects undertaken (at the global scale, in the UK, US, Canada, Switzerland and in Israel) were strongly correlated in terms of the proportion of questions and/or horizon scanning topics selected when comparing different topic areas. However, some major differences were found across regions. There was large variation among regions in the percentage of proactive (i.e. action and response oriented) versus descriptive (non-response oriented) priority questions and in the emphasis given to socio-political issues. Substantial differences were also found when comparing outcomes of priority questions versus horizon scanning projects undertaken for the same region. For example, issues related to climate change, human demography and marine ecosystems received higher priority as horizon scanning topics, while ecosystem services were more emphasized as current priority questions. We suggest that future initiatives aimed at identifying priority conservation questions and horizon scanning topics should allow simultaneous identification of both current and future priority issues, as presented here for the first time. We propose that further emphasis on social-political issues should be explicitly integrated into future

    The number of elderly workers has also been increasing and poor psychological well-being in elderly workers has been reported. The aim of this study is to elucidate the factors that are related to poor psychological well-being in elderly workers. We administered General Health Questionnaire-12 (GHQ-12) as an indicator of psychological well-being to 330 male elderly workers in the age range of 50-69, and analyzed different psychological factors, namely sense of coherence (SOC), and physical and lifestyle variables such as blood pressure, serum total cholesterol, smoking frequency, alcohol intake, exercise frequency, and body mass index (BMI) that are related to GHQ-12. When the cut-off point of GHQ-12 was 2/3, 97 workers who showed high GHQ-12 score were classified as one group having poor psychological well-being. A statistically significantly lower SOC score, higher stress score, lower frequency of exercise, higher smoking score and higher BMI, but not longer working hours or higher shift work score in the workers with higher GHQ-12 scores were observed than in the workers with normal GHQ-12 scores. Multiple logistic regression analysis showed that the low SCO score, low frequency of exercise, high smoking frequency and high BMI significantly contributed to the high GHQ-12 score. A low SOC score in elderly workers is assumed to be directly related to poor psychological well-being, or via the development of lifestyle problems such as lack of exercise, obesity, and smoking in elderly workers. This assumption must be confirmed by conducting future intervention studies on lifestyle.

    The paper recapitulates some key elements in previously published results concerning exact and complete reconstitution of the field of natural numbers, both as ordinal and as cardinal numbers, from systematic unfoldment of the Fibonacci algorithm. By this natural numbers emerge as Fibonacci 'atoms' and 'molecules' consistent with the notion of Zeckendorf sums. Here, the sub-set of prime numbers appears not as the primary numbers, but as an epistructure from a deeper Fibonacci constitution, and is thus targeted from a 'positive approach'. In the Fibonacci reconstitution of number theory natural numbers show a double geometrical aspect: partly as extension in space and partly as position in a successive structuring of space. More specifically, the natural numbers are shown to be distributed by a concise 5:3 code structured from the Fibonacci algorithm via Pascal's triangle. The paper discusses possible implications for the more general relation between number theory and geometry, as well as more specifically in relation to hadronic mathematics, initiated by R.M. Santilli, and also briefly to some other recent science linking number theory more directly to geometry and natural systems

More specifically, the natural numbers are shown to be distributed by a concise 5:3 code structured from the Fibonacci algorithm via Pascal's triangle. The paper discusses possible implications for the more general relation between number theory and geometry, as well as more specifically in relation to hadronic mathematics, initiated by R.M. Santilli, and also briefly to some other recent science linking number theory more directly to geometry and natural systems.

  8. Questioning minimal deterrence

    Nuclear deterrence has yet to be adapted to the geo-strategic context of the aftermath of the Cold War. While nuclear weapons continue to play a vital role in the military policy of the five officially recognized nuclear Powers, an unprecedent reduction of their stocks o weapons is taking shape. Hidden behind the idea and the notion of minimum deterrence are a number of ambiguities or misunderstandings. It is easy to conceive of minimum deterrence in relation to previous state of affairs, namely that of the Cold War, which was noteworthy for the arms race. Alternatively, minimum deterrence could be approached solely from the point of view of the number of devices on which it was intended to be based

    The beginnings and development of the nuclear arms race from 1945 to 1987 is recounted. Alongside the arms race, the campaign to abolish nuclear weapons was born and has grown. The key moments and events in its development are considered and certain themes followed. These include the growing awareness of scientists of the part they play in modern warfare and their reactions to this, the different methods used by politicians and military leaders to diffuse unwelcome comment and the discrepancy between words and action. The peace movement has developed all over the world but this book deals mostly with its activities in the Western democracies. Political and religious aspects and public opinion about the peace movement are considered. (U.K.)

  10. Diverse Cone-Snail Species Harbor Closely Related Streptomyces Species with Conserved Chemical and Genetic Profiles, Including Polycyclic Tetramic Acid Macrolactams

    Full Text Available Streptomyces are Gram-positive bacteria that occupy diverse ecological niches including host-associations with animals and plants. Members of this genus are known for their overwhelming repertoire of natural products, which has been exploited for almost a century as a source of medicines and agrochemicals. Notwithstanding intense scientific and commercial interest in Streptomyces natural products, surprisingly little is known of the intra- and/or inter-species ecological roles played by these metabolites. In this report we describe the chemical structures, biological properties, and biosynthetic relationships between natural products produced by Streptomyces isolated from internal tissues of predatory Conus snails, collected from the Great Barrier Reef, Australia. Using chromatographic, spectroscopic and bioassays methodology, we demonstrate that Streptomyces isolated from five different Conus species produce identical chemical and antifungal profiles – comprising a suite of polycyclic tetramic acid macrolactams (PTMs. To investigate possible ecological (and evolutionary relationships we used genome analyses to reveal a close taxonomic relationship with other sponge-derived and free-living PTM producing Streptomyces (i.e., Streptomyces albus. In-depth phylogenomic analysis of PTM biosynthetic gene clusters indicated PTM structure diversity was governed by a small repertoire of genetic elements, including discrete gene acquisition events involving dehydrogenases. Overall, our study shows a Streptomyces-Conus ecological relationship that is concomitant with specific PTM chemical profiles. We provide an evolutionary framework to explain this relationship, driven by anti-fungal properties that protect Conus snails from fungal pathogens.

  11. Figures of merit and constraints from testing general relativity using the latest cosmological data sets including refined COSMOS 3D weak lensing

    We use cosmological constraints from current data sets and a figure of merit approach in order to probe any deviations from general relativity at cosmological scales. The figure of merit approach is used to study and compare the constraining power of various combinations of data sets on the modified gravity (MG) parameters. We use the recently refined HST-COSMOS weak-lensing tomography data, the ISW-galaxy cross correlations from 2MASS and SDSS luminous red galaxy surveys, the matter power spectrum from SDSS-DR7 (MPK), the WMAP7 temperature and polarization spectra, the baryon acoustic oscillations from Two-Degree Field and SDSS-DR7, and the Union2 compilation of type Ia supernovae, in addition to other bounds from Hubble parameter measurements and big bang nucleosynthesis. We use three parametrizations of MG parameters that enter the perturbed field equations. In order to allow for variations of the parameters with the redshift and scale, the first two parametrizations use recently suggested functional forms while the third is based on binning methods. Using the first parametrization, we find that the CMB+ISW+WL combination provides the strongest constraints on the MG parameters followed by CMB+WL or CMB+MPK+ISW. Using the second parametrization or the binning methods, we find that the combination CMB+MPK+ISW consistently provides some of the strongest constraints. This shows that the constraints are parametrization dependent. We find that adding up current data sets does not improve consistently the uncertainties on MG parameters due to tensions between the best-fit MG parameters preferred by different data sets. Furthermore, some functional forms imposed by the parametrizations can lead to an exacerbation of these tensions. Next, unlike some studies that used the CFHTLS lensing data, we do not find any deviation from general relativity using the refined HST-COSMOS data, confirming previous claims in those studies that their result may have been due to some

  13. Analysis of the impact of climate change on groundwater related hydrological fluxes: a multi-model approach including different downscaling methods

    Directory of Open Access Journals (Sweden)

    S. Stoll

    2011-01-01

    Full Text Available Climate change related modifications in the spatio-temporal distribution of precipitation and evapotranspiration will have an impact on groundwater resources. This study presents a modelling approach exploiting the advantages of integrated hydrological modelling and a broad climate model basis. We applied the integrated MIKE SHE model on a perialpine, small catchment in northern Switzerland near Zurich. To examine the impact of climate change we forced the hydrological model with data from eight GCM-RCM combinations showing systematic biases which are corrected by three different statistical downscaling methods, not only for precipitation but also for the variables that govern potential evapotranspiration. The downscaling methods are evaluated in a split sample test and the sensitivity of the downscaling procedure on the hydrological fluxes is analyzed. The RCMs resulted in very different projections of potential evapotranspiration and, especially, precipitation. All three downscaling methods reduced the differences between the predictions of the RCMs and all corrected predictions showed no future groundwater stress which can be related to an expected increase in precipitation during winter. It turned out that especially the timing of the precipitation and thus recharge is very important for the future development of the groundwater levels. However, the simulation experiments revealed the weaknesses of the downscaling methods which directly influence the predicted hydrological fluxes, and thus also the predicted groundwater levels. The downscaling process is identified as an important source of uncertainty in hydrological impact studies, which has to be accounted for. Therefore it is strongly recommended to test different downscaling methods by using verification data before applying them to climate model data.

The original multiple-choice questions were administered in another similar introductory physics course on final exam. Findings suggest that carefully designed multiple-choice...

  15. A new delimitation of the Afro-Eurasian plant genus Althenia to include its Australasian relative, Lepilaena (Potamogetonaceae) - Evidence from DNA and morphological data.

    2016-05-01

    Althenia (Potamogetonaceae) is an aquatic plant genus disjunctly distributed in the southern- (South Africa's Cape Floristic Region: CFR) and northern- (Mediterranean Eurasia) hemispheres. This genus and its Australasian relative, Lepilaena, share similar floral characters yet have been treated as different genera or sections of Althenia sensu lato (s.l.) due to the isolated geographic distribution as well as the differences in sex expression, stamen construction, and stigma morphology. The diagnostic characters, however, need reevaluation over the boundaries between the entities. Here we tested the taxonomic delimitation between the entities, assessed synapomorphies for evolutionary lineages, and inferred biogeographic history in a phylogenetic framework. Our results indicated that Lepilaena was resolved as non-monophyletic in both plastid DNA and nuclear PhyC trees and Althenia was nested within it. As Althenia has nomenclatural priority, we propose a new delimitation to recognize Althenia s.l., which can be diagnosed by the female flowers with 3-segmented perianths and male flowers with perianths. The previously used diagnostic characters are either autapomorphies or synapomorphies for small lineages within Althenia s.l., and evolutionary transitions to sessile female flowers and narrow leaves characterize larger clades. Biogeographic analyses suggested a Miocene origin of Althenia s.l. in Australasia and indicated at least one inter- and one intra-specific inter-continental dispersal events among Australasia, Mediterranean Eurasia, and CFR need to be hypothesized to explain the current distribution patterns.

  17. Drone Use in Monioring Open Ocean Surface Debris, Including Paired Manta and Tucker Trawls for Relateing Sea State to Vertical Debris Distribution

    Science.gov (United States)

    Lattin, G.

    2016-02-01

    Monitoring debris at sea presents challenges not found in beach or riverine habitats, and is typically done with trawl nets of various apertures and mesh sizes, which limits the size of debris captured and the area surveyed. To partially overcome these limitations in monitoring floating debris, a Quadcopter drone with video transmitting and recording capabilities was deployed at the beginning and the end of manta trawl transects within the North Pacific Subtropical Gyre's eastern convergence zone. Subsurface tucker trawls at 10 meters were conducted at the same time as the manta trawls, in order to assess the effect of sea state on debris dispersal. Trawls were conducted on an 11 station grid used repeatedly since 1999. For drone observations, the operator and observer were stationed on the mother ship while two researchers collected observed debris using a rigid inflatable boat (RIB). The drone was flown to a distance of approximately 100 meters from the vessel in a zigzag or circular search pattern. Here we examine issues arising from drone deployment during the survey: 1) relation of area surveyed by drone to volume of water passing through trawl; 2) retrieval of drone-spotted and associated RIB spotted debris. 3) integrating post- flight image analysis into retrieved debris quantification; and 4) factors limiting drone effectiveness at sea. During the survey, debris too large for the manta trawl was spotted by the drone, and significant debris not observed using the drone was recovered by the RIB. The combination of drone sightings, RIB retrieval, and post flight image analysis leads to improved monitoring of debris at sea. We also examine the issue of the distribution of floating debris during sea states varying from 0-5 by comparing quantities from surface manta trawls to the tucker trawls at a nominal depth of 10 meters.

    The prevalence of depressive symptoms is high in patients with systemic sclerosis (SSc, scleroderma). This study was conducted to determine which disease-related and psychosocial factors are associated with depressive symptoms, independent of sociodemographic factors. In total, 215 patients with SSc completed questionnaires on sociodemographics, physical functioning (HAQ-DI), pain (VAS), fatigue (CIS), psychosocial characteristics (CISS, ICQ, PRQ, ASE, FoP-Q-SF) and depressive symptoms (CES-D). Disease characteristics (disease duration, disease subtype, modified Rodnan Skin Score) were collected. Hierarchical linear regression analyses were conducted to assess associations with depressive symptoms. The mean CES-D score was 12.9 (SD=9.7) and the prevalence of patients scoring>= 16 and>=19 were 32.1% and 25.1%, respectively. The variance explained by sociodemographics and disease characteristics was negligible (R(2)≤.09). Fatigue and pain were independently associated with depressive symptoms (R(2) change=.35). After adding psychological factors (R(2) change=.21), satisfaction with social support, emotion-focused coping and helplessness were also significantly associated with depressive symptoms. Higher fear of progression was associated with more depressive symptoms (P≤.01), and appearance self-esteem showed a marginally significant association (P=.08). Depressive symptoms were common in the present sample of patients with SSc and were independently associated with pain, fatigue, social support, emotion-focused coping, helplessness and fear of progression. Results suggest that, in addition to assessment of disease characteristics, attention should be given also to psychosocial factors found to be associated with depressive symptoms. For the development and trialling of psychological interventions, fear of progression could be an important target. Copyright © 2011 Elsevier Inc. All rights reserved.

    The IL-6/STAT3/NF-κB positive feedback loop links inflammation to cancer and maintains cells at a transformed state. Similarly, cancer-associated myofibroblats remains active even in absence of cancer cells. However, the molecular basis of this sustained active state remains elusive. We have shown here that breast cancer cells and IL-6 persistently activate breast stromal fibroblasts through the stimulation of the positive IL-6/STAT3/NF-κB feedback loop. Transient neutralization of IL-6 in culture inhibited this signaling circuit and reverted myofibrobalsts to a normalized state, suggesting the implication of the IL-6 autocrine feedback loop as well. Importantly, the IL-6/STAT3/NF-κB pro-inflammatory circuit was also active in cancer-associated fibroblasts isolated from breast cancer patients. Transient inhibition of STAT3 by specific siRNA in active fibroblasts persistently reduced the level of the RNA binding protein AUF1, blocked the loop and normalized these cells. Moreover, we present clear evidence that AUF1 is also part of this positive feedback loop. Interestingly, treatment of breast myofibroblasts with caffeine, which has been previously shown to persistently inhibit active breast stromal fibroblasts, blocked the positive feedback loop through potent and sustained inhibition of STAT3, AKT, lin28B and AUF1. These results indicate that the IL-6/STAT3/NF-κB positive feedback loop includes AUF1 and is responsible for the sustained active status of cancer-associated fibroblasts. We have also shown that normalizing myofibroblasts, which could be of great therapeutic value, is possible through the inhibition of this procarcinogenic circuit.

    Full Text Available Abstract Background To assess the feasibility of a randomised controlled trial of a licensed premises intervention to reduce severe intoxication and disorder; to establish effect sizes and identify appropriate approaches to the development and maintenance of a rigorous research design and intervention implementation. Methods An exploratory two-armed parallel randomised controlled trial with a nested process evaluation. An audit of risk factors and a tailored action plan for high risk premises, with three month follow up audit and feedback. Thirty-two premises that had experienced at least one assault in the year prior to the intervention were recruited, match paired and randomly allocated to control or intervention group. Police violence data and data from a street survey of study premises’ customers, including measures of breath alcohol concentration and surveyor rated customer intoxication, were used to assess effect sizes for a future definitive trial. A nested process evaluation explored implementation barriers and the fidelity of the intervention with key stakeholders and senior staff in intervention premises using semi-structured interviews. Results The process evaluation indicated implementation barriers and low fidelity, with a reluctance to implement the intervention and to submit to a formal risk audit. Power calculations suggest the intervention effect on violence and subjective intoxication would be raised to significance with a study size of 517 premises. Conclusions It is methodologically feasible to conduct randomised controlled trials where licensed premises are the unit of allocation. However, lack of enthusiasm in senior premises staff indicates the need for intervention enforcement, rather than voluntary agreements, and on-going strategies to promote sustainability.

    2005-12-01

    The issue of unfairness arises in high-stakes public examinations when students choose questions from alternatives that are offered and marks on the alternatives turn out to be discrepant. This paper addresses and defines unfairness and discrepancy in the context of alternative questions in Physics Tertiary Entrance Examinations (TEE) in Western Australia. As well, I present an analysis of question characteristics that explain observed marks-differences. The characteristics mainly relate to the construction of the text of questions, the detail on diagrams, and requirements for calculation. The list of characteristics could inform the setting of compulsory as well as alternative examination questions. The paper includes a brief exploration of results by gender on the alternative Physics TEE questions.

    2014-05-01

    Full Text Available The purpose of this study was to compare results obtained from various methodologies for genome-wide association studies, when applied to real data, in terms of number and commonality of regions identified and their genetic variance explained, computational speed, and possible pitfalls in interpretations of results. Methodologies include: two iteratively reweighted single-step genomic BLUP procedures (ssGWAS1 and ssGWAS2, a single-marker model (CGWAS, and BayesB. The ssGWAS methods utilize genomic breeding values (GEBVs based on combined pedigree, genomic and phenotypic information, while CGWAS and BayesB only utilize phenotypes from genotyped animals or pseudo-phenotypes. In this study, ssGWAS was performed by converting GEBVs to SNP marker effects. Unequal variances for markers were incorporated for calculating weights into a new genomic relationship matrix. SNP weights were refined iteratively. The data was body weight at 6 weeks on 274,776 broiler chickens, of which 4553 were genotyped using a 60k SNP chip. Comparison of genomic regions was based on genetic variances explained by local SNP regions (20 SNPs. After 3 iterations, the noise was greatly reduced of ssGWAS1 and results are similar to that of CGWAS, with 4 out of the top 10 regions in common. In contrast, for BayesB, the plot was dominated by a single region explaining 23.1% of the genetic variance. This same region was found by ssGWAS1 with the same rank, but the amount of genetic variation attributed to the region was only 3%. These finding emphasize the need for caution when comparing and interpreting results from various methods, and highlight that detected associations, and strength of association, strongly depends on methodologies and details of implementations. BayesB appears to overly shrink regions to zero, while overestimating the amount of genetic variation attributed to the remaining SNP effects. The real world is most likely a compromise between methods and remains to

    Little is known about the usefulness of the Hearing Handicap Inventory for the Elderly-Screening (HHIE-S) and a single question (SQ) in assessing hearing impairment (HI) and the impact of HI on quality of life (QOL). The objective of this study was to examine the reliability, validity, and associations with QOL measures (i.e., subjective well-being, depressive symptoms, subjective loneliness, and physical functioning) of the HHIE-S and the SQ in the elderly community. A self-report questionnaire including HHIE-S, SQ, Philadelphia Geriatric Center Morale Scale, Geriatric Depression Scale, UCLA Loneliness Scale, and the Tokyo Metropolitan Institute of Gerontology Index of Competence was administered to community elderly (781 males and 950 females). Among them, 97 males and 100 females also responded voluntarily to a request for test-retest and auditory tests. The criterion validity was tested by using pure-tone averages. Regarding the reliability of HHIE-S, Cronbach's alpha coefficient was 0.91, Spearman-Brown coefficient was 0.90, and intra-class correlation coefficient was 0.85. Regarding the test-retest reliability of SQ, kappa coefficient was 0.65. HHIE-S had significantly lower sensitivity in identifying >25-dB HI, but significantly higher specificity for the detection of >40-dB HI than SQ. HHIE-S had stronger associations with QOL measures than did SQ. HHIE-S had high reliability, while SQ had insufficient reliability. HHIE-S was more specific in detecting HI and more sensitive in assessing the impact of HI on QOL than SQ. HHIE-S is a more effective instrument for assessing HI and QOL research than SQ in the elderly community.

    2017-03-01

    Multiple choice questions (MCQs) are the most common written test item in medical examinations. Writing MCQs is difficult and cues can decrease test validity. The aim of this article is to describe the prevalence and pattern of cues in surgical MCQs in the central German medical examination questions from 2000-2011. All surgical questions were entered into a database. The questions were reviewed for cues and pseudocues independently by three students of different academic background and one clinical physician. Initially, 1014 questions were included, 22 questions were not rated uniformly by the reviewers and 3 questions were excluded because no consensus could be reached. Overall 15.2 % of the questions analyzed contained some type of cue or pseudocue. Of the total questions 0.2 % contained type A cues (i.e. disruption of grammatical flow), 6.5 % contained type B cues (i.e. heterogeneous length or differentiation), 4.0 % contained type C cues (two or more answers described closely related topics, serving to focus attention), 0.6 % contained type D convergence cues (i.e. answers with the most items in common with distractors are correct), 0.7 % contained type E verbal association cues (i.e. connection in the use of words leading to the correct answer) and 1.0 % contained type F cues (i.e. answers with absolute terms). Pseudocues were found in 3.7 % of the questions. The proportion of questions that contained cues or pseudocues should lead to further efforts to avoid such factors compromising test reliability by specific attention in the process of question design and review. Cues are still an important consideration in designing MCQs and are present in considerable numbers in medical state examination questions. Pseudocues should be explicitly avoided so as not to compromise validity and reliability.

  10. From Question Answering to Visual Exploration

    Research in Question Answering has focused on the quality of information retrieval or extraction using the metrics of precision and recall to judge success; these metrics drive toward finding the specific best answer(s) and are best supportive of a lookup type of search. These do not address the opportunity that users? natural language questions present for exploratory interactions. In this paper, we present an integrated Question Answering environment that combines a visual analytics tool for unstructured text and a state-of-the-art query expansion tool designed to compliment the cognitive processes associated with an information analysts work flow. Analysts are seldom looking for factoid answers to simple questions; their information needs are much more complex in that they may be interested in patterns of answers over time, conflicting information, and even related non-answer data may be critical to learning about a problem or reaching prudent conclusions. In our visual analytics tool, questions result in a comprehensive answer space that allows users to explore the variety within the answers and spot related information in the rest of the data. The exploratory nature of the dialog between the user and this system requires tailored evaluation methods that better address the evolving user goals and counter cognitive biases inherent to exploratory search tasks.

  20. Key Questions in Marine Megafauna Movement Ecology

    KAUST Repository

    Hays, Graeme C.

    2016-03-12

    It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish. Research on these taxa has both underpinned many of the recent technical developments and led to fundamental discoveries in the field. We show that the questions have broad applicability to other taxa, including terrestrial animals, flying insects, and swimming invertebrates, and, as such, this exercise provides a useful roadmap for targeted deployments and data syntheses that should advance the field of movement ecology. Technical advances make this an exciting time for animal movement studies, with a range of small, reliable data-loggers and transmitters that can record horizontal and vertical movements as well as aspects of physiology and reproductive biology.Forty experts identified key questions in the field of movement ecology.Questions have broad applicability across species, habitats, and spatial scales, and apply to animals in both marine and terrestrial habitats as well as both vertebrates and invertebrates, including birds, mammals, reptiles, fish, insects, and plankton. © 2016 Elsevier Ltd.

  1. Some of the unanswered questions in finance

    Directory of Open Access Journals (Sweden)

    Đurić Dragana M.

    2006-01-01

    Full Text Available A very dynamic development of finance in the last 50 years is inter alia probably due to experiments and innovations in this field. Previously theoretical base could not explain and predict movements especially in volatile times. "The new finance" appeared 50 years ago (portfolio theory CAPM, the efficient market theory, M&M theorem and made substantial progress in understanding movements in globalized and internationalized financial markets. However, many questions remain open. The author tries to put emphasis on some of these questions, perfectly aware that these are not the only ones. Unresolved questions are related to company's aims, project's risks, degree of portfolio optimization, importance of liquidity, dividend policy, as well as factors that determine M&A. As the "new finance" is not able to predict and explain volatile movements, a question that should be posed is whether it is appropriate to add some non-economic factors as the behaviorist theory suggests. Although the behaviorist theory is an important part of "new finance", it is unfortunately the only theory able to explain movements in volatile times. In conclusion, many questions still remain unanswered and wait for appropriate theoretical explanations.

    2018-03-25

    Contents Summary I. Introduction II. Six key questions III. Three key challenges IV. Conclusions Acknowledgements References SUMMARY: The origin and rapid diversification of angiosperms (flowering plants) represent one of the most intriguing topics in evolutionary biology. Despite considerable progress made in complementary fields over the last two decades (paleobotany, phylogenetics, ecology, evo-devo, genomics), many important questions remain. For instance, what has been the impact of mass extinctions on angiosperm diversification? Are the angiosperms an adaptive radiation? Has morphological evolution in angiosperms been gradual or pulsed? We propose that the recent and ongoing revolution in macroevolutionary methods provides an unprecedented opportunity to explore long-standing questions that probably hold important clues to understand present-day biodiversity. We present six key questions that explore the origin and diversification of angiosperms. We also identify three key challenges to address these questions: (1) the development of new integrative models that include diversification, multiple intrinsic and environmental traits, biogeography and the fossil record all at once, whilst accounting for sampling bias and heterogeneity of macroevolutionary processes through time and among lineages; (2) the need for large and standardized synthetic databases of morphological variation; and (3) continuous effort on sampling the fossil record, but with a revolution in current paleobotanical practice. © 2018 Royal Botanic Gardens and Domain Trust New Phytologist © 2018 New Phytologist Trust.

  3. Open Educational Resources: American Ideals, Global Questions

    2015-09-01

    Full Text Available Educational relations between societies and cultures that begin with benevolent intentions can come to be seen as threats to national autonomy and local preferences. Indeed, side by side with the growth since the first years of this century of Open Educational Resources (OER there has been worry about their impact on global educational development. Evaluation and research have lagged behind the steady expansion of access to online resources, leaving estimates of the value of digital innovation to the enthusiasm of OER providers and technology minded educational reformers. The advent of the “Massive Open Online Course” (or MOOC has exacerbated the problem, with attention moving toward a form of OER reflecting the enthusiasm of leading institutions in industrialized nations. The American led movement on behalf of the MOOC requires new questions about the motives, impact, and future of OER. This essay accounts for the history of OER, culminating in the MOOC, including how the latter in particular is an expression of American pedagogical and institutional interests representing belief in the transformative educational powers of the latest communications technologies. Criticism of OER and MOOCs can reflect organizational, operational, and ideological considerations. But it should recognize what they offer when there are few other opportunities for formal learning, and as research demonstrates their uses and impact.

    In this study, a stability-indicating reversed-phase liquid chromatographic electrospray mass spectrometric method was developed and validated for the determination of process-related impurities and forced degradants of Efavirenz in bulk drugs. Efavirenz was subjected to acid, alkaline hydrolysis, H2O2 oxidation, photolysis, and thermal stress. Significant degradation was observed during alkaline hydrolysis, and the degradants were isolated on a mass-based purification system and characterized by high-resolution mass spectrometry, positive electrospray ionization tandem mass spectrometry, and (1)H and (13)C NMR spectroscopy. Accurate mass measurement and NMR spectroscopy revealed the possible structure of process-related impurities and degradant under stress conditions. The acceptable separation was accomplished on Waters bondapak C18 column (250 mm × 4.6 mm; 5 μm), using 5 mM ammonium acetate and acetonitrile as a mobile phase in a gradient elution mode at a flow rate of 1.0 mL/min. The eluents were monitored by diode array detector at 247 nm and quantitation limits were obtained in the range of 0.1-2.5 μg/mL for Efavirenz, degradants, and process-related impurities. The liquid chromatography method was validated with respect to accuracy, precision, linearity, robustness, and limits of detection and quantification as per International Conference on Harmonization guidelines. © 2014 WILEY-VCH Verlag GmbH & Co.

  5. The central question in superconductivity

    Science.gov (United States)

    Hirsch, J. E.

    I will argue that the most basic and fundamental question in superconductivity is: when a superconductor in a magnetic field goes normal, how does the supercurrent stop? The supercurrent has to stop before the material becomes resistive because the transition is reversible in an ideal situation, with no Joule heat dissipated. I will argue that the conventional BCS-London theory of superconductivity cannot answer this question. I will propose an answer to this question that requires that there is flow and counterflow of charge across the normal-superconductor phase boundary, and requires that the normal state current carriers have hole-like character. The conventional BCS-London theory of superconductivity does not have these physical elements, the theory of hole superconductivity does.

  6. Reflective Questioning in Management Education

    Inge C. M. van Seggelen-Damen

    2014-06-01

    Full Text Available Reflective questioning is a critical activity in management learning and education. This article describes research on the nature of reflective questioning in groups of management students working on final MSc projects. Drawing on content analysis of recorded meetings, we identify the following key dimensions of reflective questioning: provocation, need for cognition, epistemology, locus of cognition, logic, heuristics, level of abstraction, and cognitive complexity. The data suggest that individual reflection by students and collective reflection in group meetings are highly complementary in management education. In particular, individual reflection by students combined with meetings that support and provoke collective reflection may create substantial synergies between individual and collective learning. We also discuss the implications of these findings for management education.

    2015-10-01

    Full Text Available 40 years after the Congress of Vienna that ended the Napoleonic Wars, European diplomats gathered in Paris. France, together with England, managed to defeat Russia in the Crimean War, and now it was crowned with the laurels of success. On the agenda of foreign policy of the Great Powers appeared Romanian question. Despite the fact that Russia was defeated, it approached to France as a result of secret negotiations between the Duke de Morny and Russian ambassador in Vienna Gorchakov in 1855. The Congress of Paris in 1856 demonstrated evidence of this rapprochement. France put forward for discussion the question of the union of two Romanian principalities that suddenly found support from Russia, which wanted to be rehabilitated to Romanians and looked for an opportunity to destroy the Franco-British alliance. Despite this, both countries warring at the time of the Crimean War, cooperated in implementing the desires of Romanians, and sometimes France was ready to concede to Russians. The Congress of Paris did not give a definitive solution on the question because of divergent views of the Great Powers, but managed to find support from Russia.

  13. An examination of the association between interviewer question type and story-grammar detail in child witness interviews about abuse.

    Feltis, Brooke B; Powell, Martine B; Snow, Pamela C; Hughes-Scholes, Carolyn H

    2010-06-01

    This study compared the effects of open-ended versus specific questions, and various types of open-ended questions, in eliciting story-grammar detail in child abuse interviews. The sample included 34 police interviews with child witnesses aged 5-15 years (M age=9 years, 9 months). The interviewers' questions and their relative sub-types were classified according to definitions reported in the child interview training literature. The children's responses were classified according to the proportion of story grammar and the prevalence of individual story grammar elements as defined by Stein and Glenn (1979). Open-ended questions were more effective at eliciting story grammar than specific questions. This finding was revealed across three age groups, two interview phases and irrespective of how question effectiveness was measured. However, not all types of open-ended questions were equally effective. Open-ended questions that encouraged a broad response, or asked the child to elaborate on a part of their account, elicited more story-grammar detail compared to open-ended questions that requested clarification of concepts or descriptions of the next (or another) activity or detail within a sequence. This study demonstrates that children's ability to provide story-grammar detail is maximised when there is minimal prompting from the interviewer. Given the association between story grammar production and victim credibility, greater guidance is warranted in interviewer training programs in relation to the effects and administration of different types of open-ended questions.

    Krackow, Elisa; Lynn, Steven Jay

    2003-12-01

    Preschool children (ages 48-70 months, N = 48) experienced 2 to-be-remembered events (i.e., the games Twister and Shapes) that included either innocuous bodily touch or no touch. Participants were interviewed 7 days later and asked direct ("Did Amy kiss you?") or suggestive "tag" questions ("Amy kissed you, didn't she?") equated for content. Results indicated that children who were innocuously touched were no more likely to falsely assent to "abuse-related" touch questions (e.g., "Amy touched your bottom, didn't she?") than were children who were not touched. However, children who were asked tag questions responded at chance levels, thereby making high errors of commission in response to abuse-touch questions relative to their no-tag counterparts who responded to "abuse questions" accurately 93% of the time. Children who were asked tag questions assented at a higher rate to general forensic questions ("Amy took your picture, didn't she?") than did children asked direct questions, and children assented at higher rates to "abuse-touch" questions than to general forensic questions. Results are discussed in terms of prior research on interviewing techniques and adult influence on children's testimony.

    Recently (1996-98), Colorado added 15 questions pertaining to injury related risks and behaviors to the behavioral risk factor surveillance system (BRFSS). Questions addressed bicycle helmet use, traffic crashes, exposure to violence, suicidal behavior, and gun storage. To measure the test-retest reliability of these injury related questions. Of 330 BRFSS participants, 229 (69%) were called a second time and reasked nine selected injury questions. Retests were completed 7-28 days after the original interview. Test-retest agreement was very high (kappa >0.80) for bicycle helmet use, domestic police visits, and gun ownership. All other injury risk questions had substantial agreement (kappa >0.60). The injury related questions added to the Colorado BRFSS have high test-retest reliability.

  17. Metacognitive effects of initial question difficulty on subsequent memory performance.

    Pansky, Ainat; Goldsmith, Morris

    2014-10-01

    In two experiments, we examined whether relative retrieval fluency (the relative ease or difficulty of answering questions from memory) would be translated, via metacognitive monitoring and control processes, into an overt effect on the controlled behavior-that is, the decision whether to answer a question or abstain. Before answering a target set of multiple-choice general-knowledge questions (intermediate-difficulty questions in Exp. 1, deceptive questions in Exp. 2), the participants first answered either a set of difficult questions or a set of easy questions. For each question, they provided a forced-report answer, followed by a subjective assessment of the likelihood that their answer was correct (confidence) and by a free-report control decision-whether or not to report the answer for a potential monetary bonus (or penalty). The participants' ability to answer the target questions (forced-report proportion correct) was unaffected by the initial question difficulty. However, a predicted metacognitive contrast effect was observed: When the target questions were preceded by a set of difficult rather than easy questions, the participants were more confident in their answers to the target questions, and hence were more likely to report them, thus increasing the quantity of freely reported correct information. The option of free report was more beneficial after initial question difficulty than after initial question ease, in terms of both the gain in accuracy (Exp. 2) and a smaller cost in quantity (Exps. 1 and 2). These results demonstrate that changes in subjective experience can influence metacognitive monitoring and control, thereby affecting free-report memory performance independently of forced-report performance.

  18. The Alevi and questions of identity, including violence and insider/outsider perspectives

    Directory of Open Access Journals (Sweden)

    Tina Hamrin-Dahl

    2006-01-01

    Full Text Available Alevilik is the second largest religious movement in Turkey after Sunnite Islam. The Alevi worship Ali and the twelve Imams of his family. Ali is more or less deified and therefore Alevis are considered as being ghulat (‘exaggerated’, ‘extremist’ and heterodox. The elevated Ali personifies an aspiration to justice and righteousness. He fought on the side of the weak and oppressed against those with power in society. Theologically, Ali is assumed to be blessed by the divine light and is therefore able to see into the mysterious spirituality of Islam. Many Alevis today however totally dissociate themselves from Shi’ism. Still, the degrading­ abel kızılbaş (‘red-head’ is associated with Ali and thus is something alleged to be anti-Osman, since Isma’il fought against the Osman Empire. The colour red represents the blood of Mohammed: he was wounded in battle and Ali saw the prophet’s blood flowing. As Ali grew older, he wanted to remind people of Mohammed’s struggle and therefore started wearing red headgear. Red thus became the colour of the Shi’ites and over time a symbol of Shi’ite martyrdom. Later red also gained political significance for the Alevis. The religious and the political are closely intertwined, but despite this, neither the Left nor Shi’ism does simply stand on one side and the Right/Sunni on the other – there are no such simple dichotomies in reality.

  2. Auto/Ethnography and the Question of Ethics

    Directory of Open Access Journals (Sweden)

    Wolff-Michael Roth

    2008-10-01

    Full Text Available Auto/ethnography has emerged as an important method in the social sciences for contributing to the project of understanding human actions and concerns. Although the name of the method includes "ethnography," auto/ethnography often is concerned exclusively with an abstract (i.e., undeveloped and abstracting understanding, and therefore the writing, of the Self rather than the writing of the "ethno." Auto/ethnography, such conceived, is a form of therapy, in the best case, and a form of narcissism and autoerotic relation, in the worst case. But because the Self exists in relation to the world, becomes in and through participation in everyday events, and because the human relation is inherently ethical, there are inherent ethical questions where the Other may come to be harmed as much as the Self.

  4. Risk patterns in drug safety study using relative times by accelerated failure time models when proportional hazards assumption is questionable: an illustrative case study of cancer risk of patients on glucose-lowering therapies.

    Science.gov (United States)

    Ng, Edmond S-W; Klungel, Olaf H; Groenwold, Rolf H H; van Staa, Tjeerd-Pieter

    2015-01-01

    Observational drug safety studies may be susceptible to confounding or protopathic bias. This bias may cause a spurious relationship between drug exposure and adverse side effect when none exists and may lead to unwarranted safety alerts. The spurious relationship may manifest itself through substantially different risk levels between exposure groups at the start of follow-up when exposure is deemed too short to have any plausible biological effect of the drug. The restrictive proportional hazards assumption with its arbitrary choice of baseline hazard function renders the commonly used Cox proportional hazards model of limited use for revealing such potential bias. We demonstrate a fully parametric approach using accelerated failure time models with an illustrative safety study of glucose-lowering therapies and show that its results are comparable against other methods that allow time-varying exposure effects. Our approach includes a wide variety of models that are based on the flexible generalized gamma distribution and allows direct comparisons of estimated hazard functions following different exposure-specific distributions of survival times. This approach lends itself to two alternative metrics, namely relative times and difference in times to event, allowing physicians more ways to communicate patient's prognosis without invoking the concept of risks, which some may find hard to grasp. In our illustrative case study, substantial differences in cancer risks at drug initiation followed by a gradual reduction towards null were found. This evidence is compatible with the presence of protopathic bias, in which undiagnosed symptoms of cancer lead to switches in diabetes medication. Copyright © 2015 John Wiley & Sons, Ltd.

  6. Neural network classification of questionable EGRET events

    Science.gov (United States)

    Meetre, C. A.; Norris, J. P.

    1992-01-01

    High energy gamma rays (greater than 20 MeV) pair producing in the spark chamber of the Energetic Gamma Ray Telescope Experiment (EGRET) give rise to a characteristic but highly variable 3-D locus of spark sites, which must be processed to decide whether the event is to be included in the database. A significant fraction (about 15 percent or 10(exp 4) events/day) of the candidate events cannot be categorized (accept/reject) by an automated rule-based procedure; they are therefore tagged, and must be examined and classified manually by a team of expert analysts. We describe a feedforward, back-propagation neural network approach to the classification of the questionable events. The algorithm computes a set of coefficients using representative exemplars drawn from the preclassified set of questionable events. These coefficients map a given input event into a decision vector that, ideally, describes the correct disposition of the event. The net's accuracy is then tested using a different subset of preclassified events. Preliminary results demonstrate the net's ability to correctly classify a large proportion of the events for some categories of questionables. Current work includes the use of much larger training sets to improve the accuracy of the net.

    The Standard Model of particle physics agrees very well with experiment, but many important questions remain unanswered, among them are the following. What is the origin of particle masses and are they due to a Higgs boson? How does one understand the number of species of matter particles and how do they mix? What is the origin of the difference between matter and antimatter, and is it related to the origin of the matter in the Universe? What is the nature of the astrophysical dark matter? How does one unify the fundamental interactions? How does one quantize gravity? In this article, I introduce these questions and discuss how they may be addressed by experiments at the Large Hadron Collider, with particular attention to the search for the Higgs boson and supersymmetry.

  8. Robustness Analysis of Visual QA Models by Basic Questions

    KAUST Repository

    Huang, Jia-Hong

    2017-09-14

    Visual Question Answering (VQA) models should have both high robustness and accuracy. Unfortunately, most of the current VQA research only focuses on accuracy because there is a lack of proper methods to measure the robustness of VQA models. There are two main modules in our algorithm. Given a natural language question about an image, the first module takes the question as input and then outputs the ranked basic questions, with similarity scores, of the main given question. The second module takes the main question, image and these basic questions as input and then outputs the text-based answer of the main question about the given image. We claim that a robust VQA model is one, whose performance is not changed much when related basic questions as also made available to it as input. We formulate the basic questions generation problem as a LASSO optimization, and also propose a large scale Basic Question Dataset (BQD) and Rscore (novel robustness measure), for analyzing the robustness of VQA models. We hope our BQD will be used as a benchmark for to evaluate the robustness of VQA models, so as to help the community build more robust and accurate VQA models.

    International Nuclear Information System (INIS)

    1988-01-01

    In 1988, the Uranium Institute, a London-based international association of industrial enterprises in the nuclear industry, published a report entitled The Safety of Nuclear Power Plants. Based on an assessment by an international group of senior nuclear experts from eight countries, the report provides an authoritative explanation, for non-specialists of the basic principles of reactor safety, their application, and their implications. Some questions and answers are selected from that report; they address only a few of the subjects that the report itself examines in greater detail

    We examine the gender balance of the 18th and 19th meetings of the Cambridge Workshop on Cool Stellar Systems and the Sun (CS18 and CS19). The percent of female attendees at both meetings (31% at CS18 and 37% at CS19) was higher than the percent of women in the American Astronomical Society (25%) and the International Astronomical Union (18%). The representation of women in Cool Stars as SOC members, invited speakers, and contributed speakers was similar to or exceeded the percent of women attending the meetings. We requested that conference attendees assist in a project to collect data on the gender of astronomers asking questions after talks. Using this data, we found that men were over-represented (and women were under-represented) in the question sessions after each talk. Men asked 79% of the questions at CS18 and 75% of the questions at CS19, but were 69% and 63% of the attendees respectively. Contrary to findings from previous conferences, we did not find that the gender balance of questions was strongly affected by the session chair gender, the speaker gender, or the length of the question period. We also found that female and male speakers were asked a comparable number of questions after each talk. The contrast of these results from previous incarnations of the gender questions survey indicate that more data would be useful in understanding the factors that contribute to the gender balance of question askers. We include a preliminary set of recommendations based on this and other work on related topics, but also advocate for additional research on the demographics of conference participants. Additional data on the intersection of gender with race, seniority, sexual orientation, ability and other marginalized identities is necessary to fully address the role of gender in asking questions at conferences.

    Initially considered as the supreme weapon against greenhouse gas emissions, biofuels are today hold responsible to all harms of the Earth: leap of agriculture products price, deforestation, food crisis. Considered some time ago as the perfect clean substitute to petroleum, biofuels are now suspected to have harmful effects on the environment. Should it be just an enormous technical, environmental and human swindle? Should we abandon immediately biofuels to protect the earth and fight the threatening again starvation? Should we wait for the second generation of efficient biofuels, made from non food-derived products and cultivation wastes? This book analyses this delicate debate through 5 main questions: do they starve the world? Are they a clean energy source? Do they contribute to deforestation? Are they economically practicable? Is the second generation ready? (J.S.)

  13. A Reflection on Teacher Questioning Types

    Full Text Available Abstract This small-scale research is expected to serve as a reflective means for teachers so that they can explore their questioning types in their own classroom. It analyzed questioning types used by three teachers of general English classes. The questioning types were classified based on three dimensions—purpose, form, and function. The purpose-based questioning types, based on Long and Sato’s findings (1983, were classified into two: referential and display. The form-based questioning types, based on the classification of question types by Celce-Murcia and Larsen-Freeman (1999 and Biber et al. (1999, were classified into four major types: yes/no-questions, wh-questions, tag questions, and alternative questions. The function-based questioning types, based on Long and Sato’s findings (1983, were classified into three sub-types: comprehension checks, confirmation checks, and clarification requests.           The data, obtained from three recorded class meetings, were transcribed and analyzed to see what questioning types each teacher employed and to obtain the number and percentage distribution of questioning types each teacher used. The results showed that referential questions were more frequently used than display questions at higher levels. There were a substantial number of incomplete questions, a form-based questioning type that did not belong to the classification of form-based questioning types employed in this study. The predominant use of incomplete questions in a communicative classroom should be reviewed as this questioning type required accuracy, rather than promoting language practice. The third type, the function-based questioning types, did not occur frequently at all the three stages. This study suggests that teachers use incomplete questions less frequently and try to use other form-based questioning types. It also encourages teachers to reflect on their own teaching and pursue their professional development.

    Given the range of fuel cycle goals and criteria, and the wide range of fuel cycle options, how can the set of options eventually be narrowed in a transparent and justifiable fashion? It is impractical to develop all options. We suggest an approach that starts by considering a range of goals for the Advanced Fuel Cycle Initiative (AFCI) and then posits seven questions, such as whether Cs and Sr isotopes should be separated from spent fuel and, if so, what should be done with them. For each question, we consider which of the goals may be relevant to eventually providing answers. The AFCI program has both ''outcome'' and ''process'' goals because it must address both waste already accumulating as well as completing the fuel cycle in connection with advanced nuclear power plant concepts. The outcome objectives are waste geologic repository capacity and cost, energy security and sustainability, proliferation resistance, fuel cycle economics, and safety. The process objectives are rea diness to proceed and adaptability and robustness in the face of uncertainties

    2018-03-10

    Problem-based learning is an educational method promoting clinical reasoning that has been implemented in many fields of health education. Questioning is a learning strategy often employed in problem-based learning sessions. To explore what is known about the influence of questioning on the promotion of clinical reasoning of students in health care education, specifically in the field of nursing and using the educational method of problem-based learning. A scoping review following Arksey and O'Malley's five stages was conducted. The CINAHL, EMBASE, ERIC, Medline, and PubMed databases were searched for articles published between the years of 2000 and 2017. Each article was summarized and analyzed using a data extraction sheet in relation to its purpose, population group, setting, methods, and results. A descriptive explication of the studies based on an inductive analysis of their findings to address the aim of the review was made. Nineteen studies were included in the analysis. The studies explored the influence of questioning on critical thinking rather than on clinical reasoning. The nature of the questions asked and the effect of higher-order questions on critical thinking were the most commonly occurring themes. Few studies addressed the use of questioning in problem-based learning. More empirical evidence is needed to gain a better understanding of the benefit of questioning in problem-based learning to promote students' clinical reasoning. Copyright © 2018 Elsevier Ltd.

  18. Questionable research practices among italian research psychologists

    Wicherts, Jelte M.; Veldkamp, Coosje L. S.; Albiero, Paolo; Cubelli, Roberto

    2017-01-01

    A survey in the United States revealed that an alarmingly large percentage of university psychologists admitted having used questionable research practices that can contaminate the research literature with false positive and biased findings. We conducted a replication of this study among Italian research psychologists to investigate whether these findings generalize to other countries. All the original materials were translated into Italian, and members of the Italian Association of Psychology were invited to participate via an online survey. The percentages of Italian psychologists who admitted to having used ten questionable research practices were similar to the results obtained in the United States although there were small but significant differences in self-admission rates for some QRPs. Nearly all researchers (88%) admitted using at least one of the practices, and researchers generally considered a practice possibly defensible if they admitted using it, but Italian researchers were much less likely than US researchers to consider a practice defensible. Participants’ estimates of the percentage of researchers who have used these practices were greater than the self-admission rates, and participants estimated that researchers would be unlikely to admit it. In written responses, participants argued that some of these practices are not questionable and they have used some practices because reviewers and journals demand it. The similarity of results obtained in the United States, this study, and a related study conducted in Germany suggest that adoption of these practices is an international phenomenon and is likely due to systemic features of the international research and publication processes.

    Desai, Michael M

    2013-01-01

    Recent advances in the mathematical analysis of models describing evolutionary dynamics are rapidly increasing our ability to make precise quantitative predictions. These advances have created a growing need for corresponding improvements in our ability to observe evolutionary dynamics in laboratory evolution experiments. High-throughput experimental methods are particularly crucial, in order to maintain many replicate populations and measure statistical differences in evolutionary outcomes at both phenotypic and genomic levels. In this paper, I describe recent technical developments which have greatly increased the throughput of laboratory evolution experiments, and outline a few promising directions for further improvements. I then highlight a few ways in which these new experimental methods can help to answer simple statistical questions about evolutionary dynamics, and potentially guide future theoretical work

    Biomedical professionals have access to a huge amount of literature, but when they use a search engine, they often have to deal with too many documents to efficiently find the appropriate information in a reasonable time. In this perspective, question-answering (QA) engines are designed to display answers, which were automatically extracted from the retrieved documents. Standard QA engines in literature process a user question, then retrieve relevant documents and finally extract some possible answers out of these documents using various named-entity recognition processes. In our study, we try to answer complex genomics questions, which can be adequately answered only using Gene Ontology (GO) concepts. Such complex answers cannot be found using state-of-the-art dictionary- and redundancy-based QA engines. We compare the effectiveness of two dictionary-based classifiers for extracting correct GO answers from a large set of 100 retrieved abstracts per question. In the same way, we also investigate the power of GOCat, a GO supervised classifier. GOCat exploits the GOA database to propose GO concepts that were annotated by curators for similar abstracts. This approach is called deep QA, as it adds an original classification step, and exploits curated biological data to infer answers, which are not explicitly mentioned in the retrieved documents. We show that for complex answers such as protein functional descriptions, the redundancy phenomenon has a limited effect. Similarly usual dictionary-based approaches are relatively ineffective. In contrast, we demonstrate how existing curated data, beyond information extraction, can be exploited by a supervised classifier, such as GOCat, to massively improve both the quantity and the quality of the answers with a +100% improvement for both recall and precision.

    We describe the dynamic discourse interactions between a teacher and her students in a third-grade science classroom. We focused on how the teacher and students initiate, prompt, respond, and provide feedback; use questioning and power strategies; and how questions are associated with power dynamics. We relate the consequences of teacher use of power to the engagement of student with subject matter. Two classroom sessions were observed and teacher-student interactions audio recorded. Data were transcribed and a method was developed for analyzing teacher-student interactions, power dynamics, and types of questions asked. Results revealed that teacher talk was twice as frequent as students' talk; questions were primarily closed-ended and task-oriented; and students asked few questions. The teacher exercised power by keeping activities organized and conventional, and utilizing subject matter. The developed methods showed us the complexity of question and power dynamics in classroom discourse and have implications for professional development and research.

    Health question-answering (QA) systems have become a typical application scenario of Artificial Intelligent (AI). An annotated question corpus is prerequisite for training machines to understand health information needs of users. Thus, we aimed to develop an annotated classification corpus of Chinese health questions (Qcorp) and make it openly accessible. We developed a two-layered classification schema and corresponding annotation rules on basis of our previous work. Using the schema, we annotated 5000 questions that were randomly selected from 5 Chinese health websites within 6 broad sections. 8 annotators participated in the annotation task, and the inter-annotator agreement was evaluated to ensure the corpus quality. Furthermore, the distribution and relationship of the annotated tags were measured by descriptive statistics and social network map. The questions were annotated using 7101 tags that covers 29 topic categories in the two-layered schema. In our released corpus, the distribution of questions on the top-layered categories was treatment of 64.22%, diagnosis of 37.14%, epidemiology of 14.96%, healthy lifestyle of 10.38%, and health provider choice of 4.54% respectively. Both the annotated health questions and annotation schema were openly accessible on the Qcorp website. Users can download the annotated Chinese questions in CSV, XML, and HTML format. We developed a Chinese health question corpus including 5000 manually annotated questions. It is openly accessible and would contribute to the intelligent health QA system development.

    To investigate the association between vaccination with Pandemrix and risk of selected neurological and immune-related diseases including narcolepsy. Population-based prospective cohort study using data from regional vaccination registries and national health registries. Seven healthcare regions in Sweden comprising 61% of the Swedish population. Study population of 3,347,467 vaccinated and 2,497,572 nonvaccinated individuals (vaccination coverage ≈ 60%) followed between 2009 and 2011 for 6.9 million person-years after exposure and 6.0 million person-years without exposure. First recorded diagnosis of neurological and immune-related diseases. Relative risks [hazard ratios (HRs) with 95% confidence intervals (CIs)] assessed using Cox regression, adjusted for covariates. For all selected neurological and immune-related outcomes under study, other than allergic vaccine reactions (for which we verified an expected increase in risk) and narcolepsy, HRs were close to 1.0 and always below 1.3. We observed a three-fold increased risk of a diagnosis of narcolepsy (HR: 2.92, 95% CI: 1.78-4.79; that is, four additional cases per 100,000 person-years) in individuals ≤ 20 years of age at vaccination and a two-fold increase (HR: 2.18, 95% CI: 1.00-4.75) amongst young adults between 21 and 30 years of age. The excess risk declined successively with increasing age at vaccination; no increase in risk was seen after 40 years of age. For a large number of selected neurological and immune-related diseases, we could neither confirm any causal association with Pandemrix nor refute entirely a small excess risk. We confirmed an increased risk for a diagnosis of narcolepsy in individuals ≤ 20 years of age and observed a trend towards an increased risk also amongst young adults between 21 and 30 years. © 2013 The Association for the Publication of the Journal of Internal Medicine.

    Full Text Available This paper summarises the Universidad Nacional de Colombia’s Electrical and Electronic Engineering Department’s Electromag- netic Compatibility Research Group (EMC-UNC activities during the last 30 years. The group was involved in developing experimental tools during the early 1980s, such as constructing high-voltage apparatus, developing high-voltage practical work for students and observing electrical discharges. These tools enabled the group to spend a decade focused on resolving one of the Colombian electrical sector’s main EMC problems: distribution transformer’s failures caused by lightning. For almost a decade this investigation was focused on understanding the causes of the extremely high failure index in Colombian rural areas, especially in the Rionegro basin. The main result of this investigation was a reduction by one order of magnitude in mean 10% distribution transformer failure rate. During this research work a noticeable pattern was observed of several electrically-isolated me- tallic bodies immersed in an electric field (i.e. floating electrodes. This was led to initiating floating electrode studies and for mulating a new scientific question, “How do corona electrical discharges interact with floating electrodes?” This new research question was dealt with during the second half of the 1990s and the first decade of the 2000s. This investigation was related to using electrostatically-accumulated charge on a floating electrode. This question opened up four research areas: gas discharge physics, generating fast current impulses, harvesting energy from the electric field and the possibility of high impedance current sources. This paper has summarised the most relevant work done by the EMC-UNC group on these topics. This floating electrode research work started by formulating four patents. Fresh research questions for the 2010s were related to measuring lightning electromagnetic pulses (LEMP, intentional electromagnetic

    Siemens announced in January 26, 2009 its decision to leave Areva NP, i.e. the Areva/Siemens common daughter company for reactors. This news re-launches the questions about the long-term financing strategy of the Areva group, of its capitalistic partnerships and of its position in the world nuclear market. Siemens on its side wishes to preserve its position in this market and a possible cooperation with the Russian AtomEnergoProm is under discussion. Areva, the world leader of nuclear industry, integrates a mining activity as well and is the world number 3 of uranium exploitation (15% of the world offer). It wishes to double its production by 2012 thanks to big investments in Niger, Namibia and Canada. Areva is developing its enrichment capacities as well thanks to the future Georges-Besse II ultracentrifugation facility which is under construction at Tricastin (Drome, France) and which should be put into service in 2009. And finally, a second EPR (European pressurized reactor), the new generation of Areva reactors, is to be built at Penly (Haute Normandie, France) between 2012 and 2017 and will generate 1400 employments in the region.

    Full Text Available We argue that some word order phenomena in Romanian and Sardinian are the result of a checking operation in the left periphery involving verum focus (i.e. focus on the polarity component of the sentence. In particular, this operation accounts for some word order patterns found in polar questions. In Romanian, polarity fronting is realized as head-movement of (V+T to a higher peripheral head which bears a Focus-probe. This licenses VS orders for predications in which VS is not allowed as a neutral order (i-level predicates, iteratives, generics. In Sardinian, an entire phrase headed by the lexical predicate (verbal non-finite form or non-verbal predicate is fronted before the auxiliary. We argue that this order is obtained by two movement operations, head-raising of Aux to Foc and movement of the predicate phrase to SpecFoc. We also present the semantics of polarity focus, distinguishing several types of focus (informational, emphatic, contrastive.

In Romanian,polarity fronting is realized as head-movement of (V+T to a higher peripheral head which bears a Focusprobe.This licenses VS orders for predications in which VS is not allowed as a neutral order (i-levelpredicates, iteratives, generics. In Sardinian, an entire phrase headed by the lexical predicate (verbal nonfiniteform or non-verbal predicate is fronted before the auxiliary. We argue that this order is obtained bytwo movement operations, head-raising of Aux to Foc and movement of the predicate phrase to SpecFoc. Wealso present the semantics of polarity focus, distinguishing several types of focus (informational, emphatic,contrastive.

  17. Frequently Asked Questions: The Higgs!

    2012-01-01

    Why have we tried so hard to find the Higgs particle? How does the Higgs mechanism work? What is the difference in physics between strong evidence and a discovery? Why do physicists speak in terms of "sigmas"? Find out here!   Why have we tried so hard to find the Higgs particle? Because it could be the answer to the question: how does Nature decide whether or not to assign mass to particles? All the fundamental particles making up matter – the electron, the quarks, etc. – have masses. Moreover, quantum physics requires that forces are also carried by particles. The W and Z particles that carry the weak force responsible for radioactivity must also have masses, whereas the photon, the carrier of the electromagnetic force, has no mass at all. This is the root of the “Higgs problem”: how to give masses to the fundamental particles and break the symmetry between the massive W and Z and the massless photon? Just assigning masses by hand...

  19. Three growing questions about Masonry

    2017-07-01

    Full Text Available Through three capital questions, this short essay tries to offer a general panorama and a better understanding of the proteiform complex body or Masonry. Through by a multi-level hermeneutic, this study get the ambition to be comprehensible both to Readers who are not used to this kind of literature and to the ones advanced and skilled in symbolic thought. The main important conclusion owes the quality of the symbolic level, which is the property to refuse a single interpretation: notwithstanding, this does not prevent from a clear historical and political evaluation of the phenomena under analysis, according the methodologies of social sciences. This political evaluability drives to the main valuable output of the essay, which concerns the anthropological statement that the logical label of Masonry, with this name or many others, it exists since always. Under the category of initiatory institution, we may consider the step between individual and society, and a society inside a larger one. Evolving from the needs of the individuals to the ones of social groups, the matter joins to the land of political sciences. The sociological meaning can be posed under analytic view in reason of the functionalist meaning emerging from the alternative couples status-quo/emancipation and conservatism/progressivism. Through by this perspective, anyway the theme seems not to reveal much more, because this “proteiform complex body” manifest itself as something too much complex in its inner core to be considered in a way or in another. What remains is strictly symbolic, with some theological and eschatological points that refuse to be posed under restrain.

  20. 'Any questions?'--Clinicians' usage of invitations to ask questions (IAQs) in outpatient plastic surgery consultations.

    Science.gov (United States)

    Bristowe, Katherine; Patrick, Peter L

    2014-12-01

    To explore use of 'Invitations to Ask Questions' (IAQs) by plastic surgeons in outpatient consultations, and consider how type of IAQ impacts on patients' responses to, and recollection of, IAQs. Descriptive study: 63 patients were audio recorded in consultation with 5 plastic surgeons, and completed a brief questionnaire immediately after the consultation. Consultation transcripts were analyzed using inductive qualitative methods of Discourse Analysis and compared with questionnaire findings. A taxonomy of IAQs was developed, including three types of IAQ (Overt, Covert, and Borderline). Overt IAQs were rarely identified, and almost all IAQs occurred in the closing stages of the consultation. However, when an overt IAQ was used, patients always recollected being asked if they had any questions after the consultation. Patients are rarely explicitly offered the opportunity to ask questions. When this does occur, it is often in the closing stages of the consultation. Clinicians should openly encourage patients to ask questions frequently throughout the consultation, and be mindful that subtle differences in construction of these utterances may impact upon interpretation. Clear communication, of message and intention, is essential in clinical encounters to minimize misunderstanding, misinterpretation, or missed opportunities for patients to raise concerns.

  2. The Significance of Immunohistochemical Staining, Including that for Glucose Transporter Protein Isoform 1, as Related to the Clinical and Angiographic Features of Adult Soft-Tissue Hemangioma and Arteriovenous Malformation in the Head and Neck

    International Nuclear Information System (INIS)

    Lee, Ha Young; Kim, Seon Mi; Choi, Jin Woo

    2009-01-01

    Glucose transporter protein isoform 1 (GLUT1) has been introduced to diagnose the hemangiomas of infancy. We investigated the usefulness of several immunohistochemical markers, including GLUT1, as related with the clinical and radiologic findings for making the diagnosis of adult subcutaneous vascular lesions in the head and neck. Materials and Methods: The 24 patients who underwent operations for soft tissue vascular lesion during the previous 7 years were included in this study. We analyzed the angiographic data, the clinical data and the immunohistochemical study results, including the GLUT1, S-100 protein and Movat pentichrome staining. Results: Twenty-two patients were confirmed to have arteriovenous malformation (AVM) and two hemangiomas, respectively. The number of lesions with positive Movat pentichrome, S-100 and GLUT1 staining in the patients with AVM and those patients with hemangioma were 22/22, 20/22 and 0/22, and 0/2, 0/2 and 0/2, respectively. For the 22 patients with AVMs, eight had a soft tissue vascular lesion at birth, 13 had cutaneous change and 15 had a change of the size of the lesion. For the 2 patients with one hemangioma each, neither patient had a soft tissue vascular lesion at birth, and both patients had cutaneous change and a change of the size of the lesion. The angiograms revealed a focal hypervascular mass (19/24) or diffuse staining (5/24) without showing significant features for making the definitive differential diagnosis. Our study revealed that none of the patients with AVM or hemangioma had GLUT1 positivity, and an arteriovenous malformation was more common than the adult-type hemangioma

  3. Core questions in domestication research.

    Zeder, Melinda A

    2015-03-17

    The domestication of plants and animals is a key transition in human history, and its profound and continuing impacts are the focus of a broad range of transdisciplinary research spanning the physical, biological, and social sciences. Three central aspects of domestication that cut across and unify this diverse array of research perspectives are addressed here. Domestication is defined as a distinctive coevolutionary, mutualistic relationship between domesticator and domesticate and distinguished from related but ultimately different processes of resource management and agriculture. The relative utility of genetic, phenotypic, plastic, and contextual markers of evolving domesticatory relationships is discussed. Causal factors are considered, and two leading explanatory frameworks for initial domestication of plants and animals, one grounded in optimal foraging theory and the other in niche-construction theory, are compared.

  4. Karl Mannheim’s Jewish Question

    Directory of Open Access Journals (Sweden)

    David Kettler

    2012-04-01

    Full Text Available In this paper, we explore Karl Mannheim’s puzzling failure (or refusal to address himself in any way to questions arising out of the position of Jews in Germany, either before or after the advent of Nazi rule—and this, notwithstanding the fact, first, that his own ethnic identification as a Jew was never in question and that he shared vivid experiences of anti-Semitism, and consequent exile from both Hungary and Germany, and, second, that his entire sociological method rested upon using one’s own most problematic social location—as woman, say, or youth, or intellectual—as the starting point for a reflexive investigation. It was precisely Mannheim’s convictions about the integral bond between thought grounded in reflexivity and a mission to engage in a transformative work of Bildung that made it effectively impossible for him to formulate his inquiries in terms of his way of being Jewish. It is through his explorations of the rise and fall of the intellectual as socio-cultural formation that Mannheim investigates his relations to his Jewish origins and confronts the disaster of 1933. The key to our puzzle is to be found in the theory of assimilation put forward in the dissertation of his student, Jacob Katz.

  5. Ras- ERK signaling in behavior: old questions and new perspectives

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available The role of Ras-ERK signaling in behavioral plasticity is well established. Inhibition studies using the blood-brain barrier permeable drug SL327 have conclusively demonstrated that this neuronal cell signaling cascade is a crucial component of the synaptic machinery implicated in the formation of various forms of long-term memory, from spatial learning to fear and operant conditioning. However, abnormal Ras-ERK signaling has also been linked to a number of neuropsychiatric conditions, including mental retardation syndromes (RASopathies, drug addiction and L-DOPA induced Dyskinesia (LID. The work recently done on these brain disorders has pointed to previously underappreciated roles of Ras-ERK in specific subsets of neurons, like GABAergic interneurons of the hippocampus or the cortex, as well as in the medium spiny neurons of the striatum. Here we will highlight the open questions related to Ras-ERK signaling in these behavioral manifestations and propose crucial experiments for the future.

    2007-01-01

    Research has shown how students can shift between different ways of communicating about natural phenomena. The point of departure in this text is that school science comprises science ways to communicate as well as everyday ways to communicate. In school science activities transitions, from for example everyday ways to explain to science ways to explain, occur and the purpose of this paper is to show what role questions play in these transitions. Data consists of video observations of a group of 24 students, 15 years of age, doing their ordinary school science work without my interference in their planning. Relevant conversations including questions were transcribed. The analysis was made by examining the establishment of relations between utterances in the transcribed conversations. Relations that bridge science and everyday language games are described in the results. Questions that were formulated in an everyday language game illustrate the difficulties of making transitions to a science language game. Without teacher guidance, students' questions are potential promoters for making the topic drift and to develop into something totally different from the topic as planned by the teacher. However, questions promote transitions to an everyday language game. These can be used by teachers for example to adjust an everyday explanation and guide students in making science knowledge useful in daily life.

  8. "Known Unknowns": Current Questions in Muscle Satellite Cell Biology.

    Science.gov (United States)

    Cornelison, Ddw

    2018-01-01

    Our understanding of satellite cells, now known to be the obligate stem cells of skeletal muscle, has increased dramatically in recent years due to the introduction of new molecular, genetic, and technical resources. In addition to their role in acute repair of damaged muscle, satellite cells are of interest in the fields of aging, exercise, neuromuscular disease, and stem cell therapy, and all of these applications have driven a dramatic increase in our understanding of the activity and potential of satellite cells. However, many fundamental questions of satellite cell biology remain to be answered, including their emergence as a specific lineage, the degree and significance of heterogeneity within the satellite cell population, the roles of their interactions with other resident and infiltrating cell types during homeostasis and regeneration, and the relative roles of intrinsic vs extrinsic factors that may contribute to satellite cell dysfunction in the context of aging or disease. This review will address the current state of these open questions in satellite cell biology. © 2018 Elsevier Inc. All rights reserved.

    Bates, Simon P.; Galloway, Ross K.; Riise, Jonathan; Homer, Danny

    2014-12-01

    We present results from a study that categorizes and assesses the quality of questions and explanations authored by students in question repositories produced as part of the summative assessment in introductory physics courses over two academic sessions. Mapping question quality onto the levels in the cognitive domain of Bloom's taxonomy, we find that students produce questions of high quality. More than three-quarters of questions fall into categories beyond simple recall, in contrast to similar studies of student-authored content in different subject domains. Similarly, the quality of student-authored explanations for questions was also high, with approximately 60% of all explanations classified as being of high or outstanding quality. Overall, 75% of questions met combined quality criteria, which we hypothesize is due in part to the in-class scaffolding activities that we provided for students ahead of requiring them to author questions. This work presents the first systematic investigation into the quality of student produced assessment material in an introductory physics context, and thus complements and extends related studies in other disciplines.

  10. ADVERSARIAL QUESTIONING AND ANSWERING STRATEGIES IN CHINESE GOVERNMENT PRESS CONFERENCES

    Directory of Open Access Journals (Sweden)

    Tingting Sun

    2010-12-01

    Full Text Available Studying political interviews and press conferences is significant as it may provide a special insight into the change in the policy of a country, and perhaps even the well-being of a society as a whole. Previous studies on broadcast interviews have identified adversarial questioning as an increasing and pervasive style in journalistic practice in the western world (Clayman and Heritage 2002a/b. The use of such adversarial style has emerged in Hong Kong — a metropolitan city deeply influenced by both Chinese and western cultures (Yip 2003. However, the general knowledge of how journalists treat public figures in other parts of the Chinese-speaking world remains relatively unknown. This study attempts to investigate the questioning and answering patterns, in particular adversarial questioning, in Chinese government press conferences which has thus far received little scholarly attention. Drawing on Clayman and Heritage’s coding system for measuring adversarial questioning in U.S. press conferences (2002b, the current study examines the question-answer sequences based on a corpus of ten government press conferences held in mainland China, and aims to present a questioning format by showing any differences in the design of questions by Chinese journalists and their foreign counterparts. The study further explores the format of the response of Chinese officials typical of these events and some possible correlation between government officials’ question-taking and their setting of the political agenda.

    2014-09-01

    The fact that USA have been reducing their oil dependence of one third within six years through the exploitation of shale gas and oil, and thus became almost self-sufficient as far as gas is concerned, and one of the most competitive country in the world again, will result in major geopolitical changes on a medium term: American imports from the Gulf will strongly decrease, the USA will become a gas exporter, Russia will have to look for other outlets, and so on. By proposing answers to twenty questions, the authors address the geopolitical, technical and social issues related to these evolutions. For example: are European source rocks as good as their American sisters? Will Europe be able to develop its resources at acceptable costs? What about the threats and issues perceived by some stakeholders like hydraulic fracturing, impact on water supply, risks of micro-earthquakes, or impact on surface environment in more urbanised environment than in the USA?

    The uncertainties in and correlations among some evaluated nuclear data are now evaluated to permit estimation of data-related uncertainties in the outputs of neutronic calculations and to focus data improvement efforts. Questions are discussed that arise in trying to obtain adequate numerical files of variance-covariance uncertainty information. These involve (1) discrepant data, (2) experimental data with incompletely reported uncertainties, (3) uncertainties in nuclear model results, (4) uncertainty data for the resonance regions and for angle and energy distributions, and (5) the role of integral data in nuclear data evaluation. The question also arises whether files of uncertainty data designed for technological applications can suffice to represent past knowledge in an evaluation that includes new data. Directions are indicated toward resolving these questions

    2014-03-01

    Newly implemented newborn screening (NBS) programs in California have resulted in a large subset of patients in whom at least two cystic fibrosis transmembrane conductance regulator (CFTR) mutations are identified, but subsequent sweat chloride analysis reveals normal or indeterminate values. These patients are diagnosed with CFTR-Related Metabolic Syndrome (CRMS). However, the natural progression and management of these patients are not clearly understood and frequently after the age of 1-year these patients are lost to follow-up with Cystic Fibrosis (CF) Centers. We present the first case of an infant who was referred to Miller Children's Hospital for a NBS positive for CF and subsequent discovery of identical mutations in six of his seven older brothers. Several siblings had positive sweat chloride results on repeat testing after the age of 3 years. We suggest the need for continued follow-up of CRMS in a CF center with diagnostic evaluation including repeat sweat chloride testing, beyond the currently recommended period. © 2013 Wiley Periodicals, Inc.

    Klemfuss, J Zoe; Quas, Jodi A; Lyon, Thomas D

    2014-01-01

    We investigated the links between questions child witnesses are asked in court, children's answers, and case outcome. Samples of acquittals and convictions were matched on child age, victim-defendant relationship, and allegation count and severity. Transcripts were coded for question types, including a previously under-examined type of potentially suggestive question, declarative questions. Children's productivity was conceptualized in a novel way by separating new from repeated content and by adjusting the definition based on the linguistic demands of the questions. Attorneys frequently used declarative questions, and disconcertingly, attorneys who used these and other suggestive questions more frequently were more likely to win their case. Open-ended and closed-ended questions elicited similar levels of productivity from children, and both elicited more productivity compared with suggestive questions. Results highlight how conceptualization of questions and answers can influence conclusions, and demonstrate the important real-world implications of attorney questioning strategies on legal cases with child witnesses.

    Social media is used increasingly by the general public to access health information. However, a lack of models for health information distribution limits the presence of publicly funded services on social media sites. The goal of the study was to present a model for delivering child health information to parents through a social media site. A Facebook site was launched for 11 months based on a question-and-answer service produced by a pediatrician and open to Facebook users over 18 years old. If the answer did not include a further referral to a health care service provider, the question was considered comprehensively answered. The site was funded by a pharmaceutical company, and it included an advertisement of a pharmaceutical product for children's fever and pain. During the study, 768 questions were submitted: an average of 69.8 (SD 31.7) per month. There were 245,533 independent Facebook users on the site, with an average of 727.0 (SD 2280.6) per day. Infections were the most common theme in questions (355/768, 46.2%). Questions were more likely to be comprehensively answered if they were related to infections (279/355, 78.6%) than questions related to non-infectious symptoms (265/423, 64.2%, P=.003). On this site aimed at parents of small children, personalized answers were an effective way of delivering information. The service is likely to have reduced the need for further contacts with a health care service provider in more than half of the cases. The site could serve as a model for publicly funded health information distribution.

    Full Text Available With their national origins in Spanish and US imperialism, and in the subsequent wake of intense waves of cultural colonisation, educated Filipinos are often at a loss about what their roots are. In order to bring much needed clarity to the ongoing debate about what it means to be Filipino, this essay will relate the past to the present by tracing the evolution of, and the continuities in, the essence of Filipino social organisation and worldview, drawing frequent comparisons with Indonesian and Thai data. The core approach taken – wherein these issues are examined through the lens of culture – is complemented with (i reflections on common Southeast Asian principles of social construction and (ii with the pinpointing of the systemic divides that prevent Filipinos from identifying with the collective whole and from growing into a nation of committed citizens. The paper is of relevance both to scholarly researchers and to others with practical interests in the region, as it will enable them to better know the people that they are or will be dealing with.

    2011-12-01

    This study explores the reconstruction of a signal using spectral quantities associated with some self-adjoint realization of an h-dependent Schrödinger operator -h2(d2/dx2)-y(x), h>0, when the parameter h tends to 0. Theoretical results in semi-classical analysis are proved. Some numerical results are also presented. We first consider as a toy model the sech2 function. Then we study a real signal given by arterial blood pressure measurements. This approach seems to be very promising in signal analysis. Indeed it provides new spectral quantities that can give relevant information on some signals as it is the case for arterial blood pressure signal. © 2011 - IOS Press and the authors.

  9. Turkish-Greek Relations and the Cyprus Question: Quo Vadis?

    Directory of Open Access Journals (Sweden)

    Fuat Aksu

    2010-05-01

    Full Text Available Se puede afirmar que el factor obstructivo en el curso general de las relaciones entre Turquía y Grecia, marcadas por la intransigencia, es la ausencia de una base para el diálogo y negociación donde se puedan establecer relaciones constructivas. Los esfuerzos de diálogo y negociación que se han ido iniciando de un tiempo a otro han sido improductivos por la falta de una base de confianza y seguridad entre ambos países. El proceso de diálogo moderado y medidas de confianza que se pusieron en marcha tras la crisis de los 90 lograron formar una base para la distensión bilateral de 1999. Al mismo tiempo, al conferirle la Unión Europea el estatus de candidato a Turquía, los contenciosos entre Turquía y Grecia pasaron de la esfera tradicional al ámbito europeo. En otras palabras, las relaciones bilaterales y sus disputas se “europeizaron”. En la fase posterior a 1999, las relaciones bilaterales se vertebraron alrededor del eje de la condicionalidad y la europeización. Aunque tal situación creó una base apropiada para el desarrollo del diálogo y la cooperación, no fue posible lograr una verdadera mejora en lo que a la solución de los problemas fundamentales se refiere. En especial, con la aceptación de la parte griega de Chipre en la Unión Europea a pesar de su rechazo del Plan Annan, se ha alterado el equilibrio desfavorablemente para los turco-chipriotas y para la misma Turquía, aumentando por ello las críticas hacia la Unión Europea. El proceso de distensión está reforzando la opinión de que es posible estar a la altura de los problemas de supra-securitización del pasado. Sin embargo, nuevos problemas están poniendo a prueba el nivel de tolerancia de las relaciones. Las relaciones, que el “ancla europea” evita que degeneren, podrían entrar en tensión en caso de que la pertenencia a la Unión Europea no se materializase en el futuro.

  10. Legal questions relating to nuclear installations close to national frontiers

    International Nuclear Information System (INIS)

    Zieger, G.

    1983-01-01

    Main emphasis is placed on the criteria to decide whether the construction and operation of a nulcear power plant close to a national frontier is permissible or not. The author discusses the relevant provisions of the international law and those of the Treaty of Rome pertaining to the settlement of conflicts between neighbour states. According to the opinion of the author, nuclear installations close to borders are incompatible with international law only if they do not comply with accepted safety standards. The international agreements do not prohibit the construction of nuclear installations close to frontiers. It would be desirable, however, the author says, to conclude international treaties providing for mutual consultation and information, thus offering a platform for discussing controversial national interests; this idea already being put into practice in customary international law.

    The foramen ovale is a remnant of the fetal circulation that remains patent in 20-25% of the adult population. Although long overlooked as a potential pathway that could produce pathologic conditions, the presence of a patent foramen ovale (PFO) has been associated with a higher than expected frequency in a variety of clinical syndromes including cryptogenic stroke, migraines, sleep apnea, platypnea-orthodeoxia, deep sea diving associated decompression illness, and high altitude pulmonary edema. A unifying hypothesis is that a chemical or particulate matter from the venous circulation crosses the PFO conduit between the right and left atria to produce a variety of clinical syndromes. Although observational studies suggest a therapeutic benefit of PFO closure compared to medical therapy alone in patients with cryptogenic stroke, 3 randomized controlled trials (RCTs) did not confirm the superiority of PFO closure for the secondary prevention of stroke. However, meta-analyses of these RCTs demonstrate a significant benefit of PFO closure over medical therapy alone. Similarly, observational studies provide support for PFO closure for symptomatic relief of migraines. But one controversial randomized study failed to replicate the results of the observational studies while another two demonstrated a partial benefit. The goal of this review is to discuss the clinical conditions associated with PFO and provide internists and primary care physicians with current data on PFO trials, and clinical insight to help guide their patients who are found to have a PFO on echocardiographic testing.

  13. Introduction strategies raise key questions.

    Key issues that must be considered before a new contraceptive is introduced center on the need for a trained provider to begin or terminate the method, its side effects, duration of use, method's ability to meet users' needs and preferences, and extra training or staff requirements. Logistics and economic issues to consider are identifying a dependable way of effectively supplying commodities, planning extra services needed for the method, and cost of providing the method. Each contraceptive method presents a different side effect pattern and burdens the service delivery setting differently. The strategy developed to introduce or expand the 3-month injectable Depo-Provera (DMPA) can be used for any method. It includes a needs assessment and addresses regulatory issues, service delivery policies and procedures, information and training, evaluation, and other concerns. Viet Nam's needs assessment showed that Norplant should not be introduced until the service delivery system becomes stronger. Any needs assessment for expansion of contraceptive services should cover sexually transmitted disease/HIV issues. A World Health Organization strategy helps officials identify the best method mix for local situations. Introductory strategies must aim to improve the quality of family planning programs and expand choices. Many begin by examining existing data and conducting interviews with policymakers, users, providers, and women's health advocates. Introductory programs for Norplant focus on provider training, adequate counseling and informed consent for users, and ready access to removal. They need a well-prepared service delivery infrastructure. The first phase of the DMPA introductory strategy for the Philippines comprised a social marketing campaign and DMPA introduction at public clinics in 10 pilot areas with strong service delivery. Successful AIDS prevention programs show that people tend to use barrier methods when they are available. USAID is currently studying

    2001-02-01

    This paper summarizes case studies developed by a group of collaborating educators. We investigated ways of speaking that encourage students to (a) formulate insightful questions about science topics and (b) express their own ideas during reflective discussions. The authors include elementary, high school, and college faculty. Subject-matter contexts included phases of the moon, motion, electricity, light, and waves. In developing case studies, we documented and interpreted student and teacher questions during the three ways of speaking we value most: guided discussions, student-generated inquiry discussions, and peer collaborations. Student questions occurred when we set up discourse structures that explicitly elicited student questions, engaged students in conversations about familiar contexts in which they had made many observations over a long time period, created comfortable discourse environments in which students could try to understand one another's thinking, and established small groups where students were collaborating with one another. Typically we elicited student thinking by asking questions that develop conceptual understanding. These included questions to help students clarify their meanings, explore various points of view in a neutral and respectful manner, and monitor the discussion and their own thinking. We also elicited student thinking by practicing quietness through long wait times, attentive silence, and reticence.

    performance by at least 10%. Similar criticisms apply to their selective use of performance measures. Finally, Feachem et al claim that Kaiser is a more integrated system than the NHS. The NHS provides health care to around 60 million people free at the point of delivery, long-term and psychiatric care, and continuing care after 100 days whereas Kaiser provides care to 6 million people, mainly employed and privately insured. Important functions, such as health protection, education and training of healthcare professionals, and research and development are not included or properly costed in Feachem et al's integrated model. We have re-examined the statements made by Feachem et al and show that the claims are unsupported by the evidence. The NHS is not similar to Kaiser in coverage, costs or performance.

  18. Dynamic Question Ordering in Online Surveys

    Directory of Open Access Journals (Sweden)

    Early Kirstin

    2017-09-01

    Full Text Available Online surveys have the potential to support adaptive questions, where later questions depend on earlier responses. Past work has taken a rule-based approach, uniformly across all respondents. We envision a richer interpretation of adaptive questions, which we call Dynamic Question Ordering (DQO, where question order is personalized. Such an approach could increase engagement, and therefore response rate, as well as imputation quality. We present a DQO framework to improve survey completion and imputation. In the general survey-taking setting, we want to maximize survey completion, and so we focus on ordering questions to engage the respondent and collect hopefully all information, or at least the information that most characterizes the respondent, for accurate imputations. In another scenario, our goal is to provide a personalized prediction. Since it is possible to give reasonable predictions with only a subset of questions, we are not concerned with motivating users to answer all questions. Instead, we want to order questions to get information that reduces prediction uncertainty, while not being too burdensome. We illustrate this framework with two case studies, for the prediction and survey-taking settings. We also discuss DQO for national surveys and consider connections between our statistics-based question-ordering approach and cognitive survey methodology.

  19. Organizational Learning: Some Basic Questions and Answers

    2014-05-01

    Full Text Available The term “organizational learning” raises a broad range of questions, specifically with regard to its contents. Following the thoughts of eminent philosophers, such as Aristotle and Confucius, the contribution of scientists in any research field to the corpus of human knowledge should also be based on the proper governing of the use of language. Therefore it is, first, of serious importance to be aware that organizational learning is just one dimension or element of the learning organization and not vice versa; second, a good comprehension of basic categories related to the organizational side of (formal social units’ functioning is an imperative part of organizational learning process. In writing this paper, the author started from his experiences acquired in his role as a lecturer on the subject “Theory of Organization”, in which the goal of lecturing was explained to students as gaining knowledge about cooperation and competition of people in the entities of rational production of goods. To generalize the presented questions and answers regarding the use of term “organization” in the field of management, certain similarities and comparisons were sought and found in other fields of science and, more generally, in life itself. After more detailed explanations of other relevant categories for the organizational learning process, the process itself is defined by its goals and steps where the overlapping of the learning process with the organizational change process and the process of increasing organizational capital is shown. Finally, it is also emphasized that the idea of improving internal relationships – as the substance of organization – between employees in a formal social unit through organizational learning could and should be exploited in external relationships between formal social units.

    Hendriana, H.; Hidayat, W.; Ristiana, M. G.

    2018-01-01

    This study was designed in the form of experiments with control group design and post-test only which aimed to examine the role of metaphorical thinking learning in the mathematical questioning ability of student teachers based on the level of mathematical courage. The population of this study was student teachers of mathematics education study program in West Java Province, while the sample of this study was 152 student teachers which were set purposively and then randomly to be included in the experimental class and control class. Based on the results and discussion, it was concluded that: (a) the mathematical questioning ability of student teachers who received Metaphorical Thinking learning was better than those who received conventional learning seen from mathematical courage level; (b) learning and mathematical courage level factors affected the achievement of student teachers’ mathematical questioning ability. In addition, there was no interaction effect between learning and mathematical courage level (high, medium, and low) simultaneously in developing student teachers’ mathematical questioning ability; (c) achievement of mastering mathematical questioning ability of student teacher was still not well achieved on indicator of problem posing in the form of non-routine question and open question.

    Full Text Available An action research study was conducted among 24 Form 4 level Malaysian students, aged 16. The duration of the study was five months and constituted 16 one-hour literature lessons (short stories from the secondary level Malaysian English Language Upper Secondary Level school syllabus. This paper describes my experience as a teacher-as-researcher to assist students to respond to teacher questions through Paul’s (1993 model of Socratic Questioning which claims to develop students’ critical thinking. Data was collected through researcher’s field notes, students’ writing tasks and student interviews which were analysed after each cycle of the action research study. Changes and adaptations were consequently made based on the data collected and upon teacher reflection to improve practice. The results of this study indicate that repeated practice of Socratic Questioning had a positive effect on student responses and writing tasks. Some of the factors affecting students’ performance included students’ language proficiency, weak reading ability and students’ anxiety towards the questioning method. These issues had to be addressed and dealt with, before Socratic Questioning could be properly implemented in the classroom.

    2008-05-01

    Predonation screening questions about sexual risk factors should provide an extra layer of safety from recently acquired infections that may be too early to be detected by testing. Donors are required to read a definition of sex as it applies to predonation screening questions each time they come to donate, but how well donors apply such definitions has not been evaluated. We aimed to determine how donors define sex when answering screening questions. In total, 1297 whole blood donors were asked in a private interview to select from a list of sexual activities which ones they believed were being asked about in sexual background questions. Donors' definitions were coded as under-inclusive, correct or over-inclusive in relation to the blood services' definition. Qualitative interviews were carried out with 21 donors to understand reasoning behind definitions. Most donors had an over-inclusive definition (58.7%) or the correct definition (31.9%). Of the 9.4% of donors who had an under-inclusive definition, 95% included both vaginal and anal sex, but not oral sex. About 9% in each group were first-time donors (P > 0.05) who had never read the definition. The qualitative interviews indicated that donors reason their definition based on their own concept of transmissible disease risk. Donors apply a range of definitions of sex when answering questions about their sexual background. This may be due to different concepts of risk activities, and required reading of the definition has little impact.

    2011-03-01

    Full Text Available To inspire new ideas in research on pollination ecology, we list the most important unanswered questions in the field. This list was drawn up by contacting 170 scientists from different areas of pollination ecology and asking them to contribute their opinion on the greatest knowledge gaps that need to be addressed. Almost 40% of them took part in our email poll and we received more than 650 questions and comments, which we classified into different categories representing various aspects of pollination research. The original questions were merged and synthesised, and a final vote and ranking led to the resultant list. The categories cover plant sexual reproduction, pollen and stigma biology, abiotic pollination, evolution of animal-mediated pollination, interactions of pollinators and floral antagonists, pollinator behaviour, taxonomy, plant-pollinator assemblages, geographical trends in diversity, drivers of pollinator loss, ecosystem services, management of pollination, and conservation issues such as the implementation of pollinator conservation. We focused on questions that were of a broad scope rather than case-specific; thus, addressing some questions may not be feasible within single research projects but constitute a general guide for future directions. With this compilation we hope to raise awareness of pollination-related topics not only among researchers but also among non-specialists including policy makers, funding agencies and the public at large.

    To identify perceived barriers to residents' questioning or challenging their seniors, to determine how these barriers affect decisions, and to assess how these barriers differ across cultures. A written questionnaire was administered to residents in teaching hospitals in the US and Japan to assess factors affecting residents' willingness to question or challenge their superiors. The responses were analyzed for statistical significance of differences between the two cultures and to determine the importance of issues affecting decisions. Questionnaires were completed by 175 US and 65 Japanese residents, with an overall response rate of 71%. Trainees from both countries believe that questioning and challenging contribute to safety. The perceived importance of specific beliefs about the workplace differed across cultures in seven out of 22 questions. Residents' decisions to make a challenge were related to the relationships and perceived response of the superiors. There was no statistical difference between the US and Japanese residents in terms of the threshold for challenging their seniors. We have identified attributes of residents' beliefs of communication, including several cross-cultural differences in the importance of values and issues affecting one's decision to question or challenge. In contrast, there was no difference in the threshold for challenging seniors by the Japanese and US residents studied. Changes in organizational and professional culture may be as important, if not more so, than national culture to encourage "speaking up". Residents should be encouraged to overcome barriers to challenging, and training programs should foster improved relationships and communication between trainers and trainees.

  8. Semi-automated categorization of open-ended questions

    Directory of Open Access Journals (Sweden)

    Matthias Schonlau

    2016-08-01

    Full Text Available Text data from open-ended questions in surveys are difficult to analyze and are frequently ignored. Yet open-ended questions are important because they do not constrain respondents’ answer choices. Where open-ended questions are necessary, sometimes multiple human coders hand-code answers into one of several categories. At the same time, computer scientists have made impressive advances in text mining that may allow automation of such coding. Automated algorithms do not achieve an overall accuracy high enough to entirely replace humans. We categorize open-ended questions soliciting narrative responses using text mining for easy-to-categorize answers and humans for the remainder using expected accuracies to guide the choice of the threshold delineating between “easy” and “hard”. Employing multinomial boosting avoids the common practice of converting machine learning “confidence scores” into pseudo-probabilities. This approach is illustrated with examples from open-ended questions related to respondents’ advice to a patient in a hypothetical dilemma, a follow-up probe related to respondents’ perception of disclosure/privacy risk, and from a question on reasons for quitting smoking from a follow-up survey from the Ontario Smoker’s Helpline. Targeting 80% combined accuracy, we found that 54%-80% of the data could be categorized automatically in research surveys.

    Full Text Available During the entire history of education, questioning has been one of the usual techniques of teaching. Despite all the changes in the education theory and technology, this technique continues to be usual, because it is an efficient tool to increase learning. Questioning is an interactive relation, which enlivens the conversation, by giving continuity to the finding of final result. Questioning should be assessed as a technique, which gives high results, when it is managed successfully and with attention towards the teacher, playing meanwhile an important role during the learning of students. Through various planed activities, I tried to influence teachers in order to plan as many questions as possible, for the development of student’s critical thinking. Taking into account the development of further activities I focused in the results extracted from the data gained from the observation of teachers, target group, consultations with teachers, and took into consideration various literature which considered this issue. This research included five teachers that teach in classes 1-5, in the ELSS “Emin Duraku” in Prizren/Kosovo. Observation consisted of two periods. Results of the first period of observation showed that while preparing the teaching work, specifically planning of questions I noticed that a big number were direct questions with a low level of thinking. The research continued by maintaining the target group focused where important discussions were held about the importance of planning the questions of different levels that helped students to understand what they read and also contributed to the increasing of their interest for reading-understanding of various school texts. Then the second period of observation was conducted. Results showed that there were differences in the planning of questions by teachers, compared to the results of the first period of observation. Conclusions of this operational research showed that students can

    2016-04-01

    This study aims to assess the validity of four self-reported questions for measuring periodontitis in a birth cohort. Full-mouth periodontal examinations (three sites/tooth) were undertaken at age 38 in a complete birth cohort born in 1972/1973 in New Zealand. Four self-reported periodontal screening questions were included ("Do you think you have gum disease"; "Has a dental professional ever told you that you have lost bone around your teeth"; "Have you ever had scaling, root planing, surgery, or other treatment for gum disease" and "Have you ever had any teeth that have become loose by themselves without some injury"), and the sensitivity and specificity of those self-reported items were calculated for individual questions and using a multivariable binary logistic regression model. Generalised linear models were used to compare relative risks for periodontitis and smoking, using the (a) clinical measures and (b) self-reported questions. Among the 895 who had periodontal examinations, the prevalence of periodontitis was 43.7, 22.8 and 12.0 %, respectively, for one or more sites with ≥4, ≥5 and ≥6 mm clinical attachment loss (AL). The specificity of the four self-reported questions was high (82-94 %), but the sensitivity was low for all, except the question: "Do you think you have gum disease". The four questions' highest combined sensitivity + specificity value was 1.33 for one or more sites with ≥4 mm AL, with the area under the receiver operating characteristic (ROC) curve being greatest for one or more sites with ≥6 mm AL, at 0.84. For the smoking-periodontitis association, the estimates of relative risk for periodontitis among smokers were as follows: (a) 1.81, 2.88 and 5.79, respectively, clinically determined to have one or more sites with ≥4, ≥5 and ≥6 mm AL and (b) 2.19, 2.17, 1.23 and 1.89, respectively, for the four self-reported questions. The four self-reported periodontal screening questions performed adequately in identifying

    Gender inequity in science and academia, especially in senior positions, is a recognised problem. The reasons are poorly understood, but include the persistence of historical gender ratios, discrimination and other factors, including gender-based behavioural differences. We studied participation in a professional context by observing question-asking behaviour at a large international conference with a clear equality code of conduct that prohibited any form of discrimination. Accounting for audience gender ratio, male attendees asked 1.8 questions for each question asked by a female attendee. Amongst only younger researchers, male attendees also asked 1.8 questions per female question, suggesting the pattern cannot be attributed to the temporary problem of demographic inertia. We link our findings to the 'chilly' climate for women in STEM, including wider experiences of discrimination likely encountered by women throughout their education and careers. We call for a broader and coordinated approach to understanding and addressing the barriers to women and other under-represented groups. We encourage the scientific community to recognise the context in which these gender differences occur, and evaluate and develop methods to support full participation from all attendees.

    The Global Horizon Scanning Project (GHSP) is an innovative initiative that aims to identify important global environmental quality research needs. Here we report 20 key research questions from Latin America (LA). Members of the Society of Environmental Toxicology and Chemistry (SETAC) LA and other scientists from LA were asked to submit research questions that would represent priority needs to address in the region. One hundred questions were received, then partitioned among categories, examined, and some rearranged during a workshop in Buenos Aires, Argentina. Twenty priority research questions were subsequently identified. These research questions included developing, improving, and harmonizing across LA countries methods for 1) identifying contaminants and degradation products in complex matrices (including biota); 2) advancing prediction of contaminant risks and effects in ecosystems, addressing lab-to-field extrapolation challenges, and understanding complexities of multiple stressors (including chemicals and climate change); and 3) improving management and regulatory tools toward achieving sustainable development. Whereas environmental contaminants frequently identified in these key questions were pesticides, pharmaceuticals, endocrine disruptors or modulators, plastics, and nanomaterials, commonly identified environmental challenges were related to agriculture, urban effluents, solid wastes, pulp and paper mills, and natural extraction activities. Several interesting research topics included assessing and preventing pollution impacts on conservation protected areas, integrating environment and health assessments, and developing strategies for identification, substitution, and design of less hazardous chemicals (e.g., green chemistry). Finally, a recurrent research need included developing an understanding of differential sensitivity of regional species and ecosystems to environmental contaminants and other stressors. Addressing these critical questions will

  7. The Question of Metropolitan Form: Introduction

    Directory of Open Access Journals (Sweden)

    Anne Vernez Moudon

    2009-11-01

    Full Text Available Posing the concept of ‘metropolitan form’ as a question, as in the call for papers for this issue of Footprint, is an absolute necessity at this stage of development of urbanised areas. Many of the papers in this issue begin with the straw-man notion of a formless agglomeration of activities and spaces, the – for lack of a better phrase – postmodern urban experience.[1] There is a persistent theme in the related literatures of architecture, urban design and urban and regional planning that the physical form of the contemporary metropolis is un-describable. Soja’s six metaphors (post-Fordist industrial, cosmopolis, expolis, fractal city, carceral archipelago, simcities are being indicative of the wide range of possible images.[2] The eight papers in this issue of Footprint take an opposite approach. They begin to trace the contours of the debate around how the noun ‘metropolitan form’ might be understood, how it might be studied, and how it might be possible to move from an empirical understanding of its structure to more intuitive design solutions.

  8. Some questions about creativity in digital age

    Directory of Open Access Journals (Sweden)

    Maksić Slavica B.

    2016-01-01

    Full Text Available The subject of interest in this paper relates to the expression of creativity from childhood to adolescence in the society today, which many mirror as the digital age. Firstly, the paper presents a Developmental model of creativity developed in a research study focused on personal explicit theories of educational researchers. The model defines key descriptors and describes the manifestations of creativity from the preschool years all the way to the adulthood, when the individual joins the labour market. Secondly, the paper focuses onto the Digital Natives concept and attempts to describe the youngsters today taking into account research results from different settings. Thirdly, in the remaining part the manifestations of creativity from the model are associated with the characteristics of young people who were born in digital age in order to enhance understanding of creativity expression in digital age. Based on a thorough examination a list of questions and needed research studies about creativity of Digital Natives is presented, under the assumption that the digital media will only be further developed and their influence over the young generations will be even more copious. The concluding remark problematizes the notion on whether everybody may be regarded as creative in the digital age realm and if so how this changes the overall meaning of the concept of creativity?.

    2013-01-01

    In this focused review we present and discuss two basic questions related to the early development of episodic memory in children: (1) “What is an episode?”, and (2) “How do preverbal children recall a specific episode of a recurring event?” First, a brief introduction to episodic memory...... is outlined. We argue in favor of employing a definition of episodic memory allowing us to investigate the development of episodic memory by purely behavioral measures. Second, research related to each of the two questions are presented and discussed, at first separately, and subsequently together. We argue...... and attempt to demonstrate, that pursuing answers to both questions is of crucial importance – both conceptually and methodologically - if we are ever to understand the early development of episodic memory. ...

  10. Cities and health: history, approaches, and key questions.

    Science.gov (United States)

    Vlahov, David; Gibble, Emily; Freudenberg, Nicholas; Galea, Sandro

    2004-12-01

    The majority of the world's population will live in cities in the next few years, and the pace of urbanization worldwide will continue to accelerate over the coming decades. Such a dramatic demographic shift can be expected to have an impact on population health. Although there has been historic interest in how city living is associated with health, this interest has waxed and waned and a cogent framework has yet to evolve that encompasses key issues in urban health. In this article, the authors discuss three alternate approaches to the study of urban health today; these include considering urban health from the perspective of a presumed urban health penalty, from an urban sprawl perspective, and more comprehensively, considering how urban living conditions may be associated with health. The authors also propose three key questions that may help guide the study and practice of urban health in coming decades. These include considering what specific features of cities are causally related to health, the extent to which these features are unique to a particular city or are different between cities, and ultimately, to what extent these features of cities are modifiable in order to allow interventions that can improve the health of urban populations.

  11. Linguistic relativity.

    Wolff, Phillip; Holmes, Kevin J

    2011-05-01

    The central question in research on linguistic relativity, or the Whorfian hypothesis, is whether people who speak different languages think differently. The recent resurgence of research on this question can be attributed, in part, to new insights about the ways in which language might impact thought. We identify seven categories of hypotheses about the possible effects of language on thought across a wide range of domains, including motion, color, spatial relations, number, and false belief understanding. While we do not find support for the idea that language determines the basic categories of thought or that it overwrites preexisting conceptual distinctions, we do find support for the proposal that language can make some distinctions difficult to avoid, as well as for the proposal that language can augment certain types of thinking. Further, we highlight recent evidence suggesting that language may induce a relatively schematic mode of thinking. Although the literature on linguistic relativity remains contentious, there is growing support for the view that language has a profound effect on thought.

    Lunar Geoscience: Key Questions for Future Lunar Exploration James W. Head, Department of Geological Sciences, Brown University, Providence, RI 02912 USA. (Invited paper/solicited talk for EGU 2014 PS2.3 Lunar session, Bernard H. Foing, Convener EGU PS2.3) The last several decades of intensive robotic exploration of the Moon has built on early Apollo and Luna exploration to provide fundamental knowledge of Earth's satellite and an excellent perspective on the most well-documented planetary body other than Earth. This new planetological perspective has raised substantial new questions about the nature of the origin of the Moon, its early differentiation and bombardment history, its internal thermal evolution, the production of its secondary crust as exemplified by the lunar maria, and tertiary crust as potentially seen in steep-sided domes and impact melt differentiates, the abundance of interior volatiles and their role in volcanic eruptions, and the abundance of surface volatiles and their concentration in polar regions. On the basis of this new information, a series of specific outstanding geoscience questions can be identified that can serve as guides for future human and robotic exploration. These include: 1) What is the nature and abundance of impact melt seas and what rock types do they produce upon differentiation and solidification? 2) Where are lunar mantle samples located on the lunar surface and what processes are responsible for placing them there? 3) What processes are responsible for producing the silica-rich viscous domes, such as those seen at Gruithuisen? 4) What are the volatile species involved in the emplacement of lunar pyroclastic deposits and what clues do they provide about deep magmatic volatiles and shallow volatile formation processes? 5) How do we account for the differing characteristics of regional dark mantling pyroclastic deposits? 6) When did mare basalt volcanism begin (earliest cryptmaria) and how and where is it manifested? 7

    1976-01-01

    After a general classification of meaningless questions in science we concentrate on empirically meaningless questions. Introducing the concepts of informationally connected, semiconnected and disconnected observers, a formalism for the analysis of the informational structure of space-time is developed. We discuss some problems of epistemological nature in cosmology and black hole physics. A number of questions like 'What was 'before' the initial singularity of the universe' or 'What is the fate of matter in gravitational collapse inside the event horizon' turn out to be empirically meaningless. We also show that a 'wormhole' does not violate causality for the set of informationally connected observers who do not enter it. (orig.) [de

    Full Text Available Question answering system is a system that allows user to state his or her information need in the form of natural language question, and return short text excerpts or even phrases as an answer. The availability of a wide and various information source and improvements in the techniques of natural language processing, information extraction (wrapper, and information retrieval give a big effect on the development of question answering system, from just answering questions in a specific domain by consulting to structured information source such as database, and like in this research, answering any questions based on information stored in an unstructured text collection. A general architecture of question answering system based on text consists of six processing stages, i.e. question analysis, document collection preprocessing, candidate document selection, candidate document analysis, answer extraction, and response generation. Application of question answering system like AnswerBus, Mulder, and Webclopedia that are developed with its own characteristics has similar processing steps as in the general architecture. Answers returned by a question answering system need to be evaluated for performance measure. This research completed with a simple question answering system application using english Bible in World English Bible (WEB version as the source of information to answer some questions.

  15. The "Good Old Days" of Courtroom Questioning: Changes in the Format of Child Cross-Examination Questions Over 60 Years.

    Zajac, Rachel; Westera, Nina; Kaladelfos, Andy

    2017-01-01

    Recent decades have seen an explosion of research into children's eyewitness capabilities and resulted in legal reform to render the adversarial trial process more child friendly. Many, however, have been left with the feeling that the most intimidating legal process for child complainants-cross-examination-has not changed meaningfully despite its potential to distort children's evidence. To test this possibility, we compared the cross-examination questioning of Australian child sexual abuse complainants in the 1950s to that used in contemporary cases. We found that the format of cross-examination questions has remained largely consistent over time, with leading questions still making up the bulk of the questions asked. The changes that we did observe, however, are concerning. Cross-examination questions posed to contemporary child complainants were less likely to be open-ended and more likely to be complex, relative to those asked in the 1950s. Crucially, contemporary complainants were asked 3 times as many cross-examination questions as they were 60 years ago. These changes are likely to have detrimental effects on child complainants and their evidence and could reduce the ability of jurors to reach just outcomes in these cases.

    than subject-extracted questions because the former are in non-canonical word order. Finally, the Intervener hypothesis suggests that only object-extracted Which-questions should be problematic, particularly for those participants with language disorders (e.g., Friedmann & Novogrodsky, 2011. An intervener is an NP that has similar properties to other NPs in the sentence, and thus results in similarity-based interference. Only object-extracted Which-questions contain an intervener (e.g., the fireman in (2b, which interferes with the chain consisting of the displaced Which-phrase, Which mailman, and its direct object gap occurring after the verb. Briefly here, only the Intervener Hypothesis was supported by our rich data set, and this was observed unambiguously for our participants with Broca’s aphasia. As an example (see Figure 1, we observed significantly greater proportion of gazes to the incorrect referent (i.e., the intervening NP in the object-extracted Which- relative to Who-questions beginning in the Verb-gap time window and extending throughout the remainder of the sentence and into the response period following the sentence. These patterns indicate lasting similarity-based interference effects during real-time sentence processing. The implications of our findings to extant accounts of sentence processing disruptions will be discussed, including accounts that root sentence comprehension impairments to memory-based interference.

  20. Promoting an active form of learning out-of-class via answering online "study questions" leads to higher than expected exam scores in General Biology.

    Gibson, Susan I

    2015-01-01

    A rising need for workers in science, technology, engineering and mathematics (STEM) fields has fueled interest in improving teaching within STEM disciplines. Numerous studies have demonstrated the benefits of active learning approaches on student learning outcomes. However, many of these studies have been conducted in experimental, rather than real-life class, settings. In addition, most of these studies have focused on in-class active learning exercises. This study tested the effects of answering questions outside of class on exam performance for General Biology students at the University of Minnesota. An online database of 1,020 multiple-choice questions covering material from the first half of the course was generated. Students in seven course sections (with an average of ∼265 students per section) were given unlimited access to the online study questions. These students made extensive use of the online questions, with students answering an average of 1,323 questions covering material from the half of the semester for which the questions were available. After students answered a set of questions, they were shown the correct answers for those questions. More specific feedback describing how to arrive at the correct answer was provided for the 73% of the questions for which the correct answers were not deemed to be self-explanatory. The extent to which access to the online study questions improved student learning outcomes was assessed by comparing the performance on exam questions of students in the seven course sections with access to the online study questions with the performance of students in course sections without access to the online study questions. Student performance was analyzed for a total of 89 different exams questions that were not included in the study questions, but that covered the same material covered by the study questions. Each of these 89 questions was used on one to five exams given to students in course sections that had access to the

    The dramatic effectiveness of statins in improving the course of atherosclerotic cardiovascular disease tends to overshadow questions of statin intolerance. Thus after more than 25 years of clinical statin use, intolerance remains a poorly understood, frustrating issue for patients and providers. It has been extraordinarily difficult to define statin intolerance and its implications for clinical practice. Here, we briefly summarize current knowledge and raise questions that need to be addressed.

    2018-02-01

    There are few studies on the value of authoring questions as a study method, the quality of the questions produced by students and student perceptions of student-authored question banks. Here we evaluate PeerWise, a widely used and free online resource that allows students to author, answer and discuss multiple-choice questions. We introduced two undergraduate medical student cohorts to PeerWise (n=603). We looked at their patterns of PeerWise usage; identified associations between student engagement and summative exam performance; and used focus groups to assess student perceptions of the value of PeerWise for learning. We undertook item analysis to assess question difficulty and quality. Over two academic years, the two cohorts wrote 4671 questions, answered questions 606 658 times and posted 7735 comments. Question writing frequency correlated most strongly with summative performance (Spearman's rank: 0.24, p=<0.001). Student focus groups found that: (1) students valued curriculum specificity; and (2) students were concerned about student-authored question quality. Only two questions of the 300 'most-answered' questions analysed had an unacceptable discriminatory value (point-biserial correlation <0.2). Item analysis suggested acceptable question quality despite student concerns. Quantitative and qualitative methods indicated that PeerWise is a valuable study tool. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

While recall questionnaires provide a more detailed picture of an individual's level of physical activity, single-item questions may be more appropriate in certain situations. The aim of this study was to evaluate two single-item physical activity questions (one absolute question and one relative question for test-retest reliability, convergent validity, and discriminant validity, in a sample of older adults. Methods Data was obtained from the Project to Prevent Falls in Veterans, a fall risk-factor screening and modification trial. One question measured absolute physical activity (seldom, moderately, vigorously active and one measured relative physical activity (more, about as, less active than peers. Test-retest reliability was examined using weighted Kappa statistics (κ in a sample of 43 subjects. Validity was assessed using correlation coefficients (r in participants who received clinical assessments (n = 159. Results The absolute physical activity question was more reliable than the relative physical activity question (κ = 0.75 vs. κ = 0.56. Convergent validity, however, was stronger for the relative physical activity question (r = 0.28 to 0.57 vs. r = 0.10 to 0.33. Discriminant validity was similar for both questions. For the relative physical activity question, there was moderate agreement when this question was re-administered seven days later, fair to moderate/good associations when compared with indicators of physical function, and little to no associations when compared with measures hypothesized to be theoretically not related to physical activity. Conclusions The relative physical activity question had the best combination of test-retest reliability, convergent validity and discriminant validity. In studies requiring a measure of physical activity, where physical activity is not the primary focus and more

    Asking questions is an essential component of the practice of science, but question-asking skills are often underemphasized in science education. In this study, we examined questions written by students as they prepared for laboratory exercises in a senior-level cell biology class. Our goals were to discover 1) what types of questions students asked about laboratory activities, 2) whether the types or quality of questions changed over time, and 3) whether the quality of questions or degree of improvement was related to academic performance. We found a majority of questions were about laboratory outcomes or seeking additional descriptive information about organisms or processes to be studied. Few questions earned the highest possible ranking, which required demonstration of extended thought, integration of information, and/or hypotheses and future experiments, although a majority of students asked such a question at least once. We found no correlation between types of student questions or improvement in questions and final grades. Only a small improvement in overall question quality was seen despite considerable practice at writing questions about science. Our results suggest that improving students' ability to generate higher-order questions may require specific pedagogical intervention.

    recall and factual questions (Watts & Anderson, 1971; Falker, 1974; Rickards, 1974, 1976). The effect of placing questions directly within textual narrative has been much less researched than the issue of placing questions before or after the reading passage. The effect of this interspersed questioning strategy as part of science textbooks is apparently unresearched to date. The purpose of the research reported here was to determine the relative effects of certain question types when these questions were interspersed throughout the reading passage in textual materials for students in university introductory biology. It was hypothesized for experimental purposes that students reading a passage in biology concepts with specific types of interspersed questions would comprehend and retain no more of that passge than students reading the same passage without interspersed questions.

    Full Text Available The key problem of successful developing of the software intensive system (SIS is adequate conceptual interactions of stakeholders at the early stages of designing. Nowadays the success of development is extremely low. It can be increased with using artificial intelligence (AI means including models of reasoning supported by the human-computer interaction in collaborative development activity. In this paper, a number of question-answer means for modeling reasoning are suggested. Such kind of means is defined and implemented in order to get effects of integrating the collective reasoning for their positive influence on the intellectual activity of designers. Question-answer means are arranged as a specialized processor opening the possibility to question-answer programming of the tasks on the conceptual stage of designing. Suggested and investigated means can be used for solving any complicated task.

    Predictive coding is arguably the currently dominant theoretical framework for the study of perception. It has been employed to explain important auditory perceptual phenomena, and it has inspired theoretical, experimental and computational modelling efforts aimed at describing how the auditory system parses the complex sound input into meaningful units (auditory scene analysis). These efforts have uncovered some vital questions, addressing which could help to further specify predictive coding and clarify some of its basic assumptions. The goal of the current review is to motivate these questions and show how unresolved issues in explaining some auditory phenomena lead to general questions of the theoretical framework. We focus on experimental and computational modelling issues related to sequential grouping in auditory scene analysis (auditory pattern detection and bistable perception), as we believe that this is the research topic where predictive coding has the highest potential for advancing our understanding. In addition to specific questions, our analysis led us to identify three more general questions that require further clarification: (1) What exactly is meant by prediction in predictive coding? (2) What governs which generative models make the predictions? and (3) What (if it exists) is the correlate of perceptual experience within the predictive coding framework? © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    Full Text Available Educational institutions use different ways to evaluate their teachers. Asking students to rate their teachers is common practice. The purpose of this research was to examine the reliability of the instruments used to evaluate the instructors in a college of medicine. This cross-sectional descriptive research used questioners that evaluated instructors. The questioner was targeting different dimensions of instructors. Item analysis in addition to exploratory factor analysis was performed on 1040questioners answered by the students of the College of Medicine of Kashan University of Medical Sciences. SPSS software was used to perform the analysis. The psychometric properties of questionnaires including Cronbach alpha was determined. The result of exploratory factor analysis and item analysis indicated that three of the subscales of the questioner showed sufficient reliability to evaluate the instructors and two subscales needed further examination. This type of evaluations is necessary to ensure quality of instructors working in an institution as well as providing reliable feedback to the instructors. The result showed that while some subscales of the questioner seems to target the concept of interest; a re-evaluation of the instrument would be valuable to increase its reliability for the administrators in the colleges.

  8. Complex systems dynamics in aging: new evidence, continuing questions.

    Cohen, Alan A

    2016-02-01

    There have long been suggestions that aging is tightly linked to the complex dynamics of the physiological systems that maintain homeostasis, and in particular to dysregulation of regulatory networks of molecules. This review synthesizes recent work that is starting to provide evidence for the importance of such complex systems dynamics in aging. There is now clear evidence that physiological dysregulation--the gradual breakdown in the capacity of complex regulatory networks to maintain homeostasis--is an emergent property of these regulatory networks, and that it plays an important role in aging. It can be measured simply using small numbers of biomarkers. Additionally, there are indications of the importance during aging of emergent physiological processes, functional processes that cannot be easily understood through clear metabolic pathways, but can nonetheless be precisely quantified and studied. The overall role of such complex systems dynamics in aging remains an important open question, and to understand it future studies will need to distinguish and integrate related aspects of aging research, including multi-factorial theories of aging, systems biology, bioinformatics, network approaches, robustness, and loss of complexity.

  9. The contemporary mindfulness movement and the question of nonself1.

    2015-08-01

    Mindfulness-based stress reduction (MBSR), mindfulness-based cognitive therapy (MBCT), and other "mindfulness"-based techniques have rapidly gained a significant presence within contemporary society. Clearly these techniques, which derive or are claimed to derive from Buddhist meditational practices, meet genuine human needs. However, questions are increasingly raised regarding what these techniques meant in their original context(s), how they have been transformed in relation to their new Western and global field of activity, what might have been lost (or gained) on the way, and how the entire contemporary mindfulness phenomenon might be understood. The article points out that first-generation mindfulness practices, such as MBSR and MBCT, derive from modernist versions of Buddhism, and omit or minimize key aspects of the Buddhist tradition, including the central Buddhist philosophical emphasis on the deconstruction of the self. Nonself (or no self) fits poorly into the contemporary therapeutic context, but is at the core of the Buddhist enterprise from which contemporary "mindfulness" has been abstracted. Instead of focussing narrowly on the practical efficacy of the first generation of mindfulness techniques, we might see them as an invitation to explore the much wider range of practices available in the traditions from which they originate. Rather, too, than simplifying and reducing these practices to fit current Western conceptions of knowledge, we might seek to incorporate more of their philosophical basis into our Western adaptations. This might lead to a genuine and productive expansion of both scientific knowledge and therapeutic possibilities. © The Author(s) 2014.

    Microbial ecology provides insights into the ecological and evolutionary dynamics of microbial communities underpinning every ecosystem on Earth. Microbial communities can now be investigated in unprecedented detail, although there is still a wealth of open questions to be tackled. Here we identify 50 research questions of fundamental importance to the science or application of microbial ecology, with the intention of summarising the field and bringing focus to new research avenues. Questions are categorised into seven themes: host-microbiome interactions; health and infectious diseases; human health and food security; microbial ecology in a changing world; environmental processes; functional diversity; and evolutionary processes. Many questions recognise that microbes provide an extraordinary array of functional diversity that can be harnessed to solve real-world problems. Our limited knowledge of spatial and temporal variation in microbial diversity and function is also reflected, as is the need to integrate micro- and macro-ecological concepts, and knowledge derived from studies with humans and other diverse organisms. Although not exhaustive, the questions presented are intended to stimulate discussion and provide focus for researchers, funders and policy makers, informing the future research agenda in microbial ecology. © FEMS 2017.

    With few exceptions, spontaneous mutation frequency and pattern are similar across tissue types and relatively constant in young to middle adulthood in wild type mice. Underrepresented in surveys of spontaneous mutations across murine tissues is the diversity of epithelial tissues. For the first time, spontaneous mutations were detected in pancreas and submaxillary gland and compared with kidney, lung, and male germ cells from five adult male Big Blue® mice. Mutation load was assessed quantitatively through measurement of mutant and mutation frequency and qualitatively through identification of mutations and characterization of recurrent mutations, multiple mutations, mutation pattern, and mutation spectrum. A total of 9.6 million plaque forming units were screened, 226 mutants were collected, and 196 independent mutations were identified. Four novel mutations were discovered. Spontaneous mutation frequency was low in pancreas and high in the submaxillary gland. The submaxillary gland had multiple recurrent mutations in each of the mice and one mutant had two independent mutations. Mutation patterns for epithelial tissues differed from that observed in male germ cells with a striking bias for G:C to A:T transitions at CpG sites. A comprehensive review of lacI spontaneous mutation patterns in young adult mice and rats identified additional examples of this mutational bias. An overarching observation about spontaneous mutation frequency in adult tissues of the mouse remains one of stability. A repeated observation in certain epithelial tissues is a higher rate of G:C to A:T transitions at CpG sites and the underlying mechanisms for this bias are not known.

    Full Text Available One of the important results of the Eastern crisis 1875-1878 was а change of the political map of the Balkan and the recognition of new states, including Romania. The declaration of independence of Romania, the participation of Romanian troops in the war against Turkey and the territorial dispute between Romania and Russia over South Bessarabia led to the actualization of the Romanian question in European diplomacy. The policy of Romania in the final stage of the Eastern crisis 1875-1878 and the process of solution the Romanian question at the Congress of Berlin in 1878 were analyzed in the article. The author focuses on the deterioration of Russian-Romanian relations as a result of the emergence of territorial disputes over South Bessarabia.

    Full Text Available Given the prevalence of the Information Literacy Competency Standards in the library profession for the past 15 years, and the heated debate that took place regarding whether or not the Framework for Information Literacy and the Standards could harmoniously co-exist, the article raises questions about the future of information literacy in higher education. We do not necessarily have answers to these questions, but offer our own perspectives, some insight into how the Standards have served New Jersey academic librarians in the past, and how we envision using the Framework and the Standards together to further information literacy instruction at our institutions. Discussions of these questions have led us to the conclusion that the Framework and the Standards serve different purposes and have different intended audiences and are thus both valuable to the library profession.

  16. Diet, health and globalization: five key questions.

    Science.gov (United States)

    Lang, T

    1999-05-01

    The present paper explores possible implications of the globalization of the food system for diet and health. The paper poses five key questions to clarify the relationship between food and globalization. The first question is what is globalization. The paper suggests that it is helpful to distinguish between economic, political, ideological and cultural processes. Globalization is also marked by internal oppositional dynamics: there are re-localization and regional tendencies which counter the global. The second question is whether there is anything new about globalization. Food has been a much traded commodity for millennia. The paper concludes that what is new about the current phases of globalization is the pace and scale of the change, and the fact that power is being concentrated into so few hands. New marketing techniques and supply-chain management consolidate these features. The third question is who is in control of the globalization era and who benefits and loses from the processes of globalization. It is argued that modern food economies are hypermarket rather than market economies, with power accruing to the distributor more than has been recognized. The fourth question concerns governance of the food system. Historically, systems of local and national government have regulated the food supply where appropriate. Now, new international systems are emerging, partly using existing bodies and partly creating new ones. The final question is of the future. Globalization is a value-laden area of study, yet its implications for dietary change and for health are considerable. The paper argues that dimensions of change can be discerned, although it would be rash to bet on which end of each dimension will emerge as dominant in the 21st century.

    Contrived in Europe to tackle the environment protection policies and management of natural resources, the principle of caution has seen since 1990 its interest developed towards the fields of food safety and public health. The importance and the relevance of questions have lead the national institute of research and safety to constitute a working group to explore the problems and the potentialities that could be linked to the explicit introduction of this principle and this in the field of the prevention of professional risks. This work tackles several aspects of the question of caution in professional medium such history, concepts, evolution...as well as cases judged exemplary ones. (N.C.)

    2018-01-01

    A study of the influence of the use of images in a conjoint analysis combined with check-all-that apply (CATA) questions on jams was carried out. The relative importance of flavor and the information presented in the label in the willingness to purchase and the perception of how healthy the product is has been evaluated. Sixty consumers evaluated the stimuli presented only in text format (session 1), and another group of 60 consumers did so by receiving the stimuli in text format along with an image of the product (session 2). In addition, for each stimulus, consumers answered a CATA question consisting of 20 terms related to their involvement with the product. The perception of healthy increased when the texts were accompanied with images and also increased when the text included information. Willingness to purchase was only influenced by the flavor of the jams. The presence of images did not influence the CATA question's choice of terms, which were influenced by the information presented in the text. The use of a check-all-that-apply question in concepts provided an interesting possibility when they were combined with the results from the conjoint analysis, improving the comprehension of consumers' perception. Using CATA questions as an alternative way of evaluating consumer involvement seems to be beneficial and should be evaluated much further. © 2017 Institute of Food Technologists®.

    The use of questioning to engage learners is critical to furthering resident education intraoperatively. Previous studies have demonstrated that higher level questioning and optimal wait times (>3 s) result in learner responses reflective of higher cognition and retention. Given the importance of intraoperative learning, we investigated question delivery in the operating room. A total of 12 laparoscopic cholecystectomies were observed and recorded. All questions were transcribed and classified using Bloom's Taxonomy, a framework associated with hierarchical levels of learning outcomes. Wait time between question end and response was recorded. Six faculty attendings and seven house officers at our institution were observed. A total of 133 questions were recorded with an average number of questions per case of 11.2. The majority of questions 112 out of 133 (84%) were classified as Bloom's levels 1-3, with only 6% of questions of the highest level. The wait time before the resident answered the question averaged 1.75 s, with attendings interceding after 2.50 s. Question complexity and wait time did not vary based on resident postgraduate year level suggesting limited tailoring of question to learner. Intraoperative questioning is not aligned with higher level thinking. The majority of questions were Bloom's level 3 or below, limiting the complexity of answer formulation. Most responses were given within 2 s, hindering opportunity to pursue higher-order thinking. This suggests including higher level questions and tailoring questions to learner level may improve retention and maximize gains. In addition, with attendings answering 20% of their own questions, increasing their wait time offers another area for teaching development. © 2017 Royal Australasian College of Surgeons.

    Full Text Available With the ever-growing volume of information on the web, the traditional search engines, returning hundreds or thousands of documents per query, become more and more demanding on the user patience in satisfying his/her information needs. Question Answering in Open Domains is a top research and development topic in current language technology. Unlike the standard search engines, based on the latest Information Retrieval (IR methods, open domain question-answering systems are expected to deliver not a list of documents that might be relevant for the user's query, but a sentence or a paragraph answering the question asked in natural language. This paper reports on the construction and testing of a Question Answering (QA system which builds on several web services developed at the Research Institute for Artificial Intelligence (ICIA/RACAI. The evaluation of the system has been independently done by the organizers of the ResPubliQA 2009 exercise and has been rated the best performing system with the highest improvement due to the natural language processing technology over a baseline state-of-the-art IR system. The system was trained on a specific corpus, but its functionality is independent on the linguistic register of the training data.

  13. Question Word in the Mandarin Language

    Directory of Open Access Journals (Sweden)

    Xu Yunyu

    2016-12-01

    Full Text Available In an interrogative sentence in Mandarin language, a question word can be placed in the beginning, middle or end of a sentence. Because of the different nation and culture, when a foreign student learns Mandarin, they find it difficult to understand the question words and the position of the question words in that language. Because of that, the writer proposes to explain such problems. This research aims to find out what are the types of question words in Mandarin, and also to explain the function and usage of question words in the Mandarin interrogative sentence. An interrogative sentence is a very important sentence. In Mandarin, the following question words: 谁(shuí “Who”,在哪里(zài nǎli “where”, 在哪儿(zài nǎ’er “where”,为什么(wèi shénme “why”, 怎么(zěnme “why”,多少(duō shǎo) “how many”,多久(duō jiǔ “how long”,什么时候 (shénme shíhòu “when”,什么(shénme “what”,做什么(zuò shénme “why”,干 什么(gàn shénme “why”,干嘛(gànma “why” and so on are used to ask “who”, “where”, “what”, “how much”, “when”, “what time”, and “why”. Those words have different functions and usage. Each sentence has a certain structure and word order. A question word can be placed in the beginning, middle, or end of a sentence. When the place is changed, there is a possibility of miscommunication.   DOI: https://doi.org/10.24071/llt.2013.160106

  14. Multidisciplinary approaches to climate change questions

    Science.gov (United States)

    Middleton, Beth A.; LePage, Ben A.

    2011-01-01

    Multidisciplinary approaches are required to address the complex environmental problems of our time. Solutions to climate change problems are good examples of situations requiring complex syntheses of ideas from a vast set of disciplines including science, engineering, social science, and the humanities. Unfortunately, most ecologists have narrow training, and are not equipped to bring their environmental skills to the table with interdisciplinary teams to help solve multidisciplinary problems. To address this problem, new graduate training programs and workshops sponsored by various organizations are providing opportunities for scientists and others to learn to work together in multidisciplinary teams. Two examples of training in multidisciplinary thinking include those organized by the Santa Fe Institute and Dahlem Workshops. In addition, many interdisciplinary programs have had successes in providing insight into climate change problems including the International Panel on Climate Change, the Joint North American Carbon Program, the National Academy of Science Research Grand Challenges Initiatives, and the National Academy of Science. These programs and initiatives have had some notable success in outlining some of the problems and solutions to climate change. Scientists who can offer their specialized expertise to interdisciplinary teams will be more successful in helping to solve the complex problems related to climate change.

  20. Formative questioning in computer learning environments: a course for pre-service mathematics teachers

    Science.gov (United States)

    Akkoç, Hatice

    2015-11-01

    This paper focuses on a specific aspect of formative assessment, namely questioning. Given that computers have gained widespread use in learning and teaching, specific attention should be made when organizing formative assessment in computer learning environments (CLEs). A course including various workshops was designed to develop knowledge and skills of questioning in CLEs. This study investigates how pre-service mathematics teachers used formative questioning with technological tools such as Geogebra and Graphic Calculus software. Participants are 35 pre-service mathematics teachers. To analyse formative questioning, two types of questions are investigated: mathematical questions and technical questions. Data were collected through lesson plans, teaching notes, interviews and observations. Descriptive statistics of the number of questions in the lesson plans before and after the workshops are presented. Examples of two types of questions are discussed using the theoretical framework. One pre-service teacher was selected and a deeper analysis of the way he used questioning during his three lessons was also investigated. The findings indicated an improvement in using technical questions for formative purposes and that the course provided a guideline in planning and using mathematical and technical questions in CLEs.
