  3. When is a research question not a research question?

    2013-06-01

    Research is undertaken to answer important questions yet often the question is poorly expressed and lacks information on the population, the exposure or intervention, the comparison, and the outcome. An optimal research question sets out what the investigator wants to know, not what the investigator might do, nor what the results of the study might ultimately contribute. The purpose of this paper is to estimate the extent to which rehabilitation scientists optimally define their research questions. A cross-sectional survey of the rehabilitation research articles published during 2008. Two raters independently rated each question according to pre-specified criteria; a third rater adjudicated all discrepant ratings. The proportion of the 258 articles with a question formulated as methods or expected contribution and not as what knowledge was being sought was 65%; 30% of questions required reworking. The designs which most often had poorly formulated research questions were randomized trials, cross-sectional and measurement studies. Formulating the research question is not purely a semantic concern. When the question is poorly formulated, the design, analysis, sample size calculations, and presentation of results may not be optimal. The gap between research and clinical practice could be bridged by a clear, complete, and informative research question.

  6. A Question of Control? Examining the Role of Control Conditions in Experimental Psychopathology using the Example of Cognitive Bias Modification Research.

    Blackwell, Simon E; Woud, Marcella L; MacLeod, Colin

    2017-10-26

    While control conditions are vitally important in research, selecting the optimal control condition can be challenging. Problems are likely to arise when the choice of control condition is not tightly guided by the specific question that a given study aims to address. Such problems have become increasingly apparent in experimental psychopathology research investigating the experimental modification of cognitive biases, particularly as the focus of this research has shifted from theoretical questions concerning mechanistic aspects of the association between cognitive bias and emotional vulnerability, to questions that instead concern the clinical efficacy of 'cognitive bias modification' (CBM) procedures. We discuss the kinds of control conditions that have typically been employed in CBM research, illustrating how difficulties can arise when changes in the types of research questions asked are not accompanied by changes in the control conditions employed. Crucially, claims made on the basis of comparing active and control conditions within CBM studies should be restricted to those conclusions allowed by the specific control condition employed. CBM studies aiming to establish clinical utility are likely to require quite different control conditions from CBM studies aiming to illuminate mechanisms. Further, conclusions concerning the clinical utility of CBM interventions cannot necessarily be drawn from studies in which the control condition has been chosen to answer questions concerning mechanisms. Appreciating the need to appropriately alter control conditions in the transition from basic mechanisms-focussed investigations to applied clinical research could greatly facilitate the translational process.

    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.

Our intention is to give a simple introduction to the physics of gases that would be helpful for newcomers to the field of hypoxia research. We will provide background knowledge about questions often asked, but without straightforward answers. What is O2 concentration, and what is O2 partial pressure? What is normoxia, and what is hypoxia? How much O2 is experienced by a cell residing in a culture dish in vitro vs in a tissue in vivo? By the way, the O2 concentration in a normoxic incubator is 18.6%, rather than 20.9% or 20%, as commonly stated in research publications. And this is strictly only valid for incubators at sea level.

  16. Examining student-generated questions in an elementary science classroom

    Science.gov (United States)

    Diaz, Juan Francisco, Jr.

    This study was conducted to better understand how teachers use an argument-based inquiry technique known as the Science Writing Heuristic (SWH) approach to address issues on teaching, learning, negotiation, argumentation, and elaboration in an elementary science classroom. Within the SWH framework, this study traced the progress of promoting argumentation and negotiation (which led to student-generated questions) during a discussion in an elementary science classroom. Speech patterns during various classroom scenarios were analyzed to understand how teacher--student interactions influence learning. This study uses a mixture of qualitative and quantitative methods. The qualitative aspect of the study is an analysis of teacher--student interactions in the classroom using video recordings. The quantitative aspect uses descriptive statistics, tables, and plots to analyze the data. The subjects in this study were fifth grade students and teachers from an elementary school in the Midwest, during the academic years 2007/2008 and 2008/2009. The three teachers selected for this study teach at the same Midwestern elementary school. These teachers were purposely selected because they were using the SWH approach during the two years of the study. The results of this study suggest that all three teachers moved from using teacher-generated questions to student-generated questions as they became more familiar with the SWH approach. In addition, all three promoted the use of the components of arguments in their dialogs and discussions and encouraged students to elaborate, challenge, and rebut each other's ideas in a non-threatening environment. This research suggests that even young students, when actively participating in class discussions, are capable of connecting their claims and evidence and generating questions of a higher-order cognitive level. These findings demand the implementation of more professional development programs and the improvement in teacher education to help

  3. Psychotherapy Outcome Research: Issues and Questions.

    2016-03-01

    Emphasis on identifying evidence-based therapies (EBTs) has increased markedly. Lists of EBTs are the rationale for recommendations for how psychotherapy provider training programs should be evaluated, professional competence assessed, and licensure and reimbursement policies structured. There are however methodological concerns that limit the external validity of EBTs. Among the most salient is the circularity inherent in randomized control trials (RCTs) of psychotherapy that constrains the manner in which the psychological problems are defined, psychotherapy can be practiced, and change evaluated. RCT studies favor therapies that focus of specific symptoms and can be described in a manual, administered reliably across patients, completed in relatively few sessions, and involve short-term evaluations of outcome. The epistemological assumptions of a natural science approach to psychotherapy research limit how studies are conducted and assessed in ways that that advantage symptom-focused approaches and disadvantage those approaches that seek to bring broad recovery-based changes. Research methods that are not limited to RCTs and include methodology to minimize the effects of "therapist allegiance" are necessary for valid evaluations of therapeutic approaches that seek to facilitate changes that are broader than symptom reduction. Recent proposals to adopt policies that dictate training, credentialing, and reimbursement based on lists of EBTs unduly limit how psychotherapy can be conceptualized and practiced, and are not in the best interests of the profession or of individuals seeking psychotherapy services.

    Horvath, Frank; Palmatier, John J

    2008-07-01

    Two major variations of polygraph "Control Question" testing, the Zone Comparison (ZoC) and the Modified General Question Test (MGQT) were evaluated. Within each, the type of control question, Exclusive or "time bar" (e.g., "Before you were 21, did you ever...") and Nonexclusive or "no time bar" (e.g., "Did you ever....?") was manipulated in a mock theft scenario, with 80 male and 40 female subjects randomly assigned to be either innocent or guilty. Polygraphic data collected by experienced field examiners were numerically scored by an evaluator blind to all aspects of the study. Decision accuracy was not related to the type of procedure (ZoC/MGQT) used or the subject's sex. Accuracy was significantly related to the type of control question [chi(2) (2) = 11.46, p = 0.003; tau c = 0.29]. Nonexclusive control questions produced greater accuracy than Exclusive control questions on both innocent and guilty subjects. These results and subjects' self-reports support the general "theory" on which control question (CQ) testing is based. The need for better empirical support of accepted dogma and current field practices is strongly indicated by these findings.

  6. Non-Destructive Testing: Sample Questions for Conduct of Examinations at Levels 1 and 2

    International Nuclear Information System (INIS)

    2010-01-01

    The International Atomic Energy Agency (IAEA) supports industrial applications of radiation technology which include non-destructive testing (NDT) under its various programmes such as individual country Technical Co-operation (TC) projects, Regional Projects and Coordinated Research Projects (CRPs). NDT technology is essentially needed for the improvement of the quality of industrial products, equipment and plants all over the world, especially in developing Member States. Trained and certified personnel is one of the essential requirements for applying this technology in industry. With this in view, the IAEA first played an important role in cooperation with the International Organisation for Standardisation (ISO) for the development of a standard for training and certification of NDT personnel, namely ISO 9712, 'Non-Destructive Testing: Qualification and Certification of Personnel'. Subsequently the syllabi and needed training materials were identified and developed for the creation of, in each of the Member States, a core group of personnel who are trained and qualified to establish the training and certification process in their respective countries. One of the important requirements for such a process is to have the examination questions for conducting the certification examinations. A need had been felt to compile the appropriate questions firstly for conducting these examinations at the national and regional levels and secondly to provide these to the certification bodies of the Member States so that they could initiate their own level 1 and 2 certification examinations. For this purpose, Experts' Task Force Meetings were convened first in Accra, Ghana and then in Vienna, Austria under the AFRA regional projects on NDT. The experts examined and discussed in detail the ISO 9712 (1999 and 2005 versions) requirements for general, specific and practical examinations for level 1 and 2 personnel. After that a set of questions has been established which are

    2017-11-01

    Full Text Available In Brief Socratic questioning, the act of asking questions in order to prompt critical thinking and reflection, expands the boundaries of librarianship by borrowing from the fields of philosophy, pedagogy, and psychology. When employed during the research consultation, Socratic questioning establishes a cooperative relationship between librarian and student that empowers the student to take agency over the interaction. Engaging learners not only academically but emotionally encourages them to become more deliberate and cognizant as they articulate their research need. This paper demonstrates how reference librarians can adjust interactions with students in order to encourage, empathize, and engage with these learners.

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.

    With the increasing appreciation of global warming impacts on ecological systems, in addition to the myriad of land management effects on water quality, the number of literature citations dealing with the effects of water temperature on freshwater fish has escalated in the past decade. Given the many biological scales at which water temperature effects have been studied, and the growing need to integrate knowledge from multiple disciplines of thermal biology to fully protect beneficial uses, we held that a survey of the most promising recent developments and an expression of some of the remaining unanswered questions with significant management implications would best be approached collectively by a diverse research community. We have identified five specific topic areas of renewed research where new techniques and critical thought could benefit coldwater stream fishes (particularly salmonids): molecular, organism, population/species, community and ecosystem, and policy issues in water quality. Our hope is that information gained through examination of recent research fronts linking knowledge at various scales will prove useful in managing water quality at a basin level to protect fish populations and whole ecosystems. Standards of the past were based largely on incipient lethal and optimum growth rate temperatures for fish species, while future standards should consider all integrated thermal impacts to the organism and ecosystem. ??

    2012-08-10

    To implement and assess the effectiveness of an assignment requiring doctor of pharmacy (PharmD) students to write examination questions for the medicinal chemistry sections of a pharmacotherapeutics course. Students were divided into groups of 5-6 and given detailed instructions and grading rubrics for writing multiple-choice examination questions on medicinal chemistry topics. The compiled student-written questions for each examination were provided to the entire class as a study aid. Approximately 5% of the student-written questions were used in course examinations. Student appreciation of and performance in the medicinal chemistry portion of the course was significantly better than that of the previous year's class. Also, students' responses on a qualitative survey instrument indicated that the assignment provided students' guidance on which concepts to focus on, helped them retain knowledge better, and fostered personal exploration of the content, which led to better performance on examinations. Adding an active-learning assignment in which students write examination questions for the medicinal chemistry portion of a pharmacotherapeutics course was an effective means of increasing students engagement in the class and knowledge of the course material.

  15. 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.

    Full Text Available The present article introduces the central elements of the research and pedagogical innovation project entitled: “The Use of Questions as a Pedagogical Strategy in the Construction of Research Problems”, developed by the students of the ‘Rizoma’ research training group of the School of Psychopedagogy, which began in the year 2009, and which forms part of the “Educational Innovations” research line of the Masters sin Education Program at UPTC. The question as strategy, pedagogy or didactics, becomes an educational option for the development of thinking processes, and contributes to an education that embraces uncertainty, in order to develop flexible thinking, as well as critical and creative attitudes towards knowledge. These qualities constitute the basis of all research tasks, and are fundamental in the education of professionals in the midst of the current, fast-moving and uncertain postmodern condition. Emerging from the students’ and teacher’s own voices, this article offers an account of this experience and characterizes the findings of this education and research work.

    Pediatric orthopaedics is tested frequently on the Orthopaedic In-Training Examination (OITE). The most recent data on the pediatrics section of the OITE were generated from content 10 years old. The purpose of this study is to assess the pediatric orthopaedic questions on the 2011 to 2014 OITE, and to compare question categories and cognitive taxonomy with previous data. Four years (2011 to 2014) of OITE questions, answers, and references were reviewed. The number of pediatric questions per year was recorded, as well as presence of a clinical photo or imaging modality. Each question was categorized and assigned a cognitive taxonomy level. Categories included: knowledge; knowledge-treatment modalities; diagnosis; diagnosis/recognition of associated conditions; diagnosis/further studies; and diagnosis/treatment. Cognitive taxonomy levels included: simple recall, interpretation of data, and advanced problem-solving. The 3 most commonly covered topics were upper extremity trauma (17.4%), scoliosis (10.1%), and developmental dysplasia of the hip (5.7%). Compared with previous data, the percentage of pediatric questions was constant (13% vs. 14%). Categorically, the more recent OITE examinations contained significantly fewer questions testing simple knowledge (19% vs. 39%, P=0.0047), and significantly more questions testing knowledge of treatment modalities (17% vs. 9%, P=0.016) and diagnosis with associated conditions (19% vs. 9%, P=0.0034). Regarding cognitive taxonomy, there was a significant increase in the average number of questions that required advanced problem-solving (57% vs. 46%, P=0.048). Significantly more questions utilized clinical photographs and imaging studies (62% vs. 48%, P=0.012). The most common reference materials provided to support correct responses included Lovell and Winter's Pediatric Orthopaedics (25.7%) and the Journal of Pediatric Orthopaedics (23.4%). Although the percentage of pediatric questions on the OITE has remained essentially

    One challenge in science education assessment is that students often focus on surface features of questions rather than the underlying scientific principles. We investigated how student written responses to constructed-response questions about photosynthesis vary based on two surface features of the question: the species of plant and the order of two question prompts. We asked four versions of the question with different combinations of the two plant species and order of prompts in an introductory cell biology course. We found that there was not a significant difference in the content of student responses to versions of the question stem with different species or order of prompts, using both computerized lexical analysis and expert scoring. We conducted 20 face-to-face interviews with students to further probe the effects of question wording on student responses. During the interviews, we found that students thought that the plant species was neither relevant nor confusing when answering the question. Students identified the prompts as both relevant and confusing. However, this confusion was not specific to a single version. PMID:25999312

    Full Text Available The subject of developmental regression in autism has gained importance and a growing number of studies have been conducted in recent years. It is a major issue indicating that there is not a unique form of autism onset. However the phenomenon itself and the concept of regression have been the subject of some debate: there is no consensus on the existence of regression, as there is no consensus on its definition. The aim of this paper is to review the research literature in this area and to introduce some conceptual questions about its existence and its definition.

    In the course of our supervisory work over the years, we have noticed that qualitative research tends to evoke a lot of questions and worries, so-called frequently asked questions (FAQs). This series of four articles intends to provide novice researchers with practical guidance for conducting high-quality qualitative research in primary care. By 'novice' we mean Master's students and junior researchers, as well as experienced quantitative researchers who are engaging in qualitative research for the first time. This series addresses their questions and provides researchers, readers, reviewers and editors with references to criteria and tools for judging the quality of qualitative research papers. This second article addresses FAQs about context, research questions and designs. Qualitative research takes into account the natural contexts in which individuals or groups function to provide an in-depth understanding of real-world problems. The research questions are generally broad and open to unexpected findings. The choice of a qualitative design primarily depends on the nature of the research problem, the research question(s) and the scientific knowledge one seeks. Ethnography, phenomenology and grounded theory are considered to represent the 'big three' qualitative approaches. Theory guides the researcher through the research process by providing a 'lens' to look at the phenomenon under study. Since qualitative researchers and the participants of their studies interact in a social process, researchers influence the research process. The first article described the key features of qualitative research, the third article will focus on sampling, data collection and analysis, while the last article focuses on trustworthiness and publishing.

  10. Effects of Re-Using a Conceptual Examination Question in Physics

    2005-12-01

    We report on a study of what happened when we recycled a conceptual examination question in a first-year university physics course. The question, which was used for three consecutive years, asked about an astronaut's experience of weighing in an orbiting space-craft. Our original intention was to use a phenomenographic approach to look for differences in students' descriptive answers. Having done that, we decided to add a study of the marks that were awarded to those answers. The first time that the question was re-used, the distribution of answers amongst our phenomenographic categories showed a decrease in the common conception that gravity is zero in the satellite and an increase in explanations in terms of free fall. When the question was re-used a second time, that difference was maintained but it was not significantly increased. The distribution of marks for the question was different over the three years in a way that appears to be unrelated to differences in students' conceptual understandings. Differences in the distribution of marks are more likely to be related to differences in marking procedures. We conclude that studies like this one have the potential to contribute to improvements in university assessment procedures. In particular we propose that phenomenographic analysis could be used in the design of marking schemes.

    ABSTRACT 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.

    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.

    Rajah-Kanagasabai, Camilla J.; Roberts, Lynne D.

    2015-01-01

    This study examined the utility of the Theory of Planned Behavior model, augmented by descriptive norms and justifications, for predicting self-reported research misconduct and questionable research practices in university students. A convenience sample of 205 research active Western Australian university students (47 male, 158 female, ages 18–53 years, M = 22, SD = 4.78) completed an online survey. There was a low level of engagement in research misconduct, with approximately one in seven students reporting data fabrication and one in eight data falsification. Path analysis and model testing in LISREL supported a parsimonious two step mediation model, providing good fit to the data. After controlling for social desirability, the effect of attitudes, subjective norms, descriptive norms and perceived behavioral control on student engagement in research misconduct and questionable research practices was mediated by justifications and then intention. This revised augmented model accounted for a substantial 40.8% of the variance in student engagement in research misconduct and questionable research practices, demonstrating its predictive utility. The model can be used to target interventions aimed at reducing student engagement in research misconduct and questionable research practices. PMID:25983709

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

    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.

    International funding for global health research is not systematically documented. We have assessed the level of research funding awarded by UK funders of international research to low- and middle-income countries or research institutions in these countries. We analysed 6165 studies; from these we selected 522 that matched our criteria and used them to evaluate research funding by pathogen, disease, research and development value chain, funding organisation and country. Investment in infectious disease research in the countries studied totalled £264 million. Distribution of research investments closely mirrored that of the UK's former colonial territories; the top five countries, and eight of the top 10, have historical links with the UK, being current or former members of the Commonwealth of Nations. HIV, malaria and neglected tropical diseases attracted the greatest investment (£219 million; 82.8%), with most studies focussing on operational and epidemiological research (£109 million; 41.3%). International financing of infectious disease research by UK funding organisations follows former colonial ties. Funding institutions should review their funding policies to ensure that they also assist low- and middle-income countries without colonial ties to address their disease burden. A global investment surveillance system is needed to map and monitor funding for international research and guide the allocation of scarce resources to reduce the global disease burden.

    Full Text Available Most Muslim theologians have argued on the basis of the ḥadīth-literature that tattooing is ḥarām (forbidden, but it is nonetheless possible to find both historical and contemporary examples indicating that, at different times and in different places, this art was practiced by certain Islamic groups. With specific reference to washm,or tattooing, it has been well documented that certain Muslim groups (e.g., the Berbers and the Bedouins in places such as Africa, Syria, Saudi Arabia, Iran and West Pakistan have used tattoos for beautification, prophylaxis and the prevention of disease. Among Islam’s lay populations, tattooing has been considered significant as a healing practice for a very long time despite the formal opinions of Islamic scholars and theologians. And while in more recent times these Muslim groups appear to have abandoned past notions about the function of tattoos, which had caused a certain waning of the practice, of late it has had a resurgence—although for reasons that differ from those of distant times. The rise of interest in tattoos among Muslims has been directly observed by a handful of contemporary researchers, and is indirectly indicated by the fact that many contemporary Muslim authorities have expressed growing concern about the practice.This development has been further spurred on by the fact that many Muslims are actively seeking advice and clarification about where Islam stands on the matter of tattoos. The aim of of this article is to sketch the background of the more formal theological discussion on tattooing (especially in the ḥadīth-literature. It also aims to examine a number of contemporary religious texts that specifically deal with Muslim theological opinions about this practice: what is considered to be the problem; and what types of arguments are employed by the selected theologians in their attempts to provide answers. Is it possible to see the renewed interest in tattoos as an example of the

If it isn't, significant problems will result for the community's treatment of materials and the EU's competitiveness, and Reach's value as a global model will become questionable. Also, the CLP regulation concerning classification, labelling and packaging of chemicals will start to come into effect as from the beginning of December. In the first phase, the question is one of classification of substances, and gradually the requirements will be applied to mixtures too. At the same time, Safety Data Sheets shall be renewed in accordance with their own transition period. The current product legislation concerning chemicals shall be fully revised by the mid-point of the decade, but before then company safety officers will have to do lots of work to change the previous routines

    This book addresses a wide range of topics, from the principles of evidence-based practice to the process and dissemination of research to unique considerations such as clinical trials, patenting, and health services research. The case for evidence-based practice and a collaborative research culture is made first, followed by a series of chapters walking the reader through the research process by way of the scientific method. One of the more unique aspects of the scope of this book is the inclusion of chapters relating to the dissemination of knowledge, manuscript publication, and how to build an academic research program. Each chapter focuses on introducing the reader to foundational principles, methodology, and terminology, and highlight case studies of radiation therapist research or experience that is relevant to provide contextual examples and inspiration to the reader.

    Clinical epidemiology is the science of human disease investigation with a focus on diagnosis, prognosis, and treatment. The generation of a reasonable question requires definition of patients, interventions, controls, and outcomes. The goal of research design is to minimize error, to ensure adequate samples, to measure input and output variables appropriately, to consider external and internal validities, to limit bias, and to address clinical as well as statistical relevance. The hierarchy of evidence for clinical decision-making places randomized controlled trials (RCT) or systematic review of good quality RCTs at the top of the evidence pyramid. Prognostic and etiologic questions are best addressed with longitudinal cohort studies.

    The North American medical physics community validates the education received by medical physicists and the clinical qualifications for medical physicists through accreditation of educational programs and certification of medical physicists. Medical physics educational programs (graduate education and residency education) are accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP), whereas medical physicists are certified by several organizations, the most familiar of which is the American Board of Radiology (ABR). In order for an educational program to become accredited or a medical physicist to become certified, the applicant must meet certain specified standards set by the appropriate organization. In this Symposium, representatives from both CAMPEP and the ABR will describe the process by which standards are established as well as the process by which qualifications of candidates for accreditation or certification are shown to be compliant with these standards. The Symposium will conclude with a panel discussion. Learning Objectives: Recognize the difference between accreditation of an educational program and certification of an individual Identify the two organizations primarily responsible for these tasks Describe the development of educational standards Describe the process by which examination questions are developed GS is Executive Secretary of CAMPEP

    Full Text Available Abstract Background As assessment has been shown to direct learning, it is critical that the examinations developed to test clinical competence in medical undergraduates are valid and reliable. The use of extended matching questions (EMQ has been advocated to overcome some of the criticisms of using multiple-choice questions to test factual and applied knowledge. Methods We analysed the results from the Extended Matching Questions Examination taken by 4th year undergraduate medical students in the academic year 2001 to 2002. Rasch analysis was used to examine whether the set of questions used in the examination mapped on to a unidimensional scale, the degree of difficulty of questions within and between the various medical and surgical specialties and the pattern of responses within individual questions to assess the impact of the distractor options. Results Analysis of a subset of items and of the full examination demonstrated internal construct validity and the absence of bias on the majority of questions. Three main patterns of response selection were identified. Conclusion Modern psychometric methods based upon the work of Rasch provide a useful approach to the calibration and analysis of EMQ undergraduate medical assessments. The approach allows for a formal test of the unidimensionality of the questions and thus the validity of the summed score. Given the metric calibration which follows fit to the model, it also allows for the establishment of items banks to facilitate continuity and equity in exam standards.

  10. Examining personal values in extreme environment contexts: Revisiting the question of generalizability

    Land-based extreme environments (e.g. polar expeditions, Antarctic research stations, confinement chambers) have often been used as analog settings for spaceflight. These settings share similarities with the conditions experienced during space missions, including confinement, isolation and limited possibilities for evacuation. To determine the utility of analog settings for understanding human spaceflight, researchers have examined the extent to which the individual characteristics (e.g., personality) of people operating in extreme environments can be generalized across contexts (Sandal, 2000) [1]. Building on previous work, and utilising new and pre-existing data, the present study examined the extent to which personal value motives could be generalized across extreme environments. Four populations were assessed; mountaineers (N =59), military personnel (N = 25), Antarctic over-winterers (N = 21) and Mars simulation participants (N = 12). All participants completed the Portrait Values Questionnaire (PVQ; Schwartz; 2) capturing information on 10 personal values. Rank scores suggest that all groups identified Self-direction, Stimulation, Universalism and Benevolence as important values and acknowledged Power and Tradition as being low priorities. Results from difference testing suggest the extreme environment groups were most comparable on Self-direction, Stimulation, Benevolence, Tradition and Security. There were significant between-group differences on five of the ten values. Overall, findings pinpointed specific values that may be important for functioning in challenging environments. However, the differences that emerged on certain values highlight the importance of considering the specific population when comparing results across extreme settings. We recommend that further research examine the impact of personal value motives on indicators of adjustment, group working, and performance. Information from such studies could then be used to aid selection and

    Integrating knowledge from across the natural and social sciences is necessary to effectively address societal tradeoffs between human use of biological diversity and its preservation. Collaborative processes can change the ways decision makers think about scientific evidence, enhance levels of mutual trust and credibility, and advance the conservation policy discourse. Canada has responsibility for a large fraction of some major ecosystems, such as boreal forests, Arctic tundra, wetlands, and temperate and Arctic oceans. Stressors to biological diversity within these ecosystems arise from activities of the country's resource-based economy, as well as external drivers of environmental change. Effective management is complicated by incongruence between ecological and political boundaries and conflicting perspectives on social and economic goals. Many knowledge gaps about stressors and their management might be reduced through targeted, timely research. We identify 40 questions that, if addressed or answered, would advance research that has a high probability of supporting development of effective policies and management strategies for species, ecosystems, and ecological processes in Canada. A total of 396 candidate questions drawn from natural and social science disciplines were contributed by individuals with diverse organizational affiliations. These were collaboratively winnowed to 40 by our team of collaborators. The questions emphasize understanding ecosystems, the effects and mitigation of climate change, coordinating governance and management efforts across multiple jurisdictions, and examining relations between conservation policy and the social and economic well-being of Aboriginal peoples. The questions we identified provide potential links between evidence from the conservation sciences and formulation of policies for conservation and resource management.

    A persistent finding is that assisted reproductive technology (ART) is associated with compromised birth outcomes, including higher risks for prematurity, low birthweight, and congenital malformations, even among singletons. Over the past decade, our research group, the Massachusetts Outcome Study of Assisted Reproductive Technology (MOSART), has evaluated pregnancy and birth outcomes among three groups of women, those women treated with ART, those with indicators of subfertility but without ART treatment, and fertile women. We have also explored the influence of infertility-related diagnoses on outcomes for women and infants. Over the course of our research, we have changed our perspective from an original focus on ART treatment parameters as the primary cause of excess morbidity to one centered instead on the underlying infertility-related diagnoses. This paper summarizes the research findings from our group that support this change in focus for infertility-based research from a primary emphasis on ART treatment to greater attention to the contribution of preexisting pathology underlying the infertility and suggests directions for future analyses.

    The feasibility of deliberately engineering Earth's climate--and the social, economic, political, and ethical issues raised by such projects--were explored by two panels at the annual meeting of the American Association for the Advancement of Science (AAAS), held in late February in San Francisco. These projects include dispersal of sulfate particles in the stratosphere to reflect sunlight, fertilizing the southern oceans with iron to stimulate phytoplankton growth, and injecting ethane or propane into the stratosphere over Antarctica to counteract ozone-depleting chemical reactions. The feasibility of such projects was the focus of the first panel. Joyce E. Penner, of Lawrence Livermore National Laboratory, describes studies of natural and anthropogenic sulfate aerosols that suggest that these chemical species reduce the solar flux reaching the Earth's surface. The research indicates it might be possible to counteract greenhouse warming, at least in part, by injecting sulfate aerosols into the stratosphere. Should such an approach be used to counteract greenhouse warming? Should any climate engineering project be considered? These sorts of questions were the focus of the second panel

The physicists, who chair the STFC's five advisory panels, have also called for structural reforms to be made to the council. They warn that unless the government takes action to reverse the situation, the UK will be "perceived as an untrustworthy partner in global projects" and predict that a brain drain of the best UK scientists to positions overseas will ensue.

    Over the last decade a convergent body of evidence has emerged from epidemiology, animal experiments and clinical trials which links low vitamin D status with a range of adverse neuropsychiatric outcomes. This research demonstrates that the timing of exposure to low vitamin D influences the nature of brain phenotypes, as exposures during gestation versus adulthood result in different phenotypes. With respect to early life exposures, there is robust evidence from rodent experiments indicating that transient developmental vitamin D (DVD) deficiency is associated with changes in brain structure, neurochemistry, gene and protein expression and behavior. In particular, DVD deficiency is associated with alterations in the dopaminergic neurotransmitter systems. In contrast, recently published animal experiments indicate that adult vitamin D (AVD) deficiency is associated with more subtle neurochemical and behavioral phenotypes. This paper explores key issues that need to be addressed in future research. There is a need to define the timing and duration of the 'critical window' during which low vitamin D status is associated with differential and adverse brain outcomes. We discuss the role for 'two-hit hypotheses', which propose that adult vitamin D deficiency leaves the brain more vulnerable to secondary adverse exposures, and thus may exacerbate disease progression. Finally, we explore the evidence implicating a role for vitamin D in rapid, non-genomic mechanisms that may involve L-type calcium channels and brain function.

    Some new developments in elementary particle physics and interaction processes are reviewed. Recent advances in the field of particle physics including the observation of an anomalous behaviour of interaction cross section at high energy levels, the deep inelastic scattering of electrons from protons, the existence of neutral currents and the relative frequency of events with high transverse pulses are pointed out. A special development is the discovery and identification of a number of new particles and processes. New advances in understanding of the structure of subelementary particles, and the combination of electromagnetic and weak interactions are described. After a discussion of the technical and instrumental requirements and possibilities in the field of elementary particle research, the role and achievements of Hungarian scientists in high-energy facilities of the Soviet Union are emphasized.

    The empirical study of language is a young field in contemporary linguistics. This being the case, and following a natural development process, the field is currently at a stage where different research methods and experimental approaches are being put into question in terms of their validity. Without pretending to provide an answer with respect to the best way to conduct linguistics related experimental research, in this article we aim at examining the process that researchers follow in the design and implementation of experimental linguistics research with a goal to validate specific theoretical linguistic analyses. First, we discuss the general challenges that experimental work faces in finding a compromise between addressing theoretically relevant questions and being able to implement these questions in a specific controlled experimental paradigm. We discuss the Granularity Mismatch Problem (Poeppel and Embick, 2005) which addresses the challenges that research that is trying to bridge the representations and computations of language and their psycholinguistic/neurolinguistic evidence faces, and the basic assumptions that interdisciplinary research needs to consider due to the different conceptual granularity of the objects under study. To illustrate the practical implications of the points addressed, we compare two approaches to perform linguistic experimental research by reviewing a number of our own studies strongly grounded on theoretically informed questions. First, we show how linguistic phenomena similar at a conceptual level can be tested within the same language using measurement of event-related potentials (ERP) by discussing results from two ERP experiments on the processing of long-distance backward dependencies that involve coreference and negative polarity items respectively in Dutch. Second, we examine how the same linguistic phenomenon can be tested in different languages using reading time measures by discussing the outcome of four self

    Emotion feeling is a phase of neurobiological activity, the key component of emotions and emotion-cognition interactions. Emotion schemas, the most frequently occurring emotion experiences, are dynamic emotion-cognition interactions that may consist of momentary/situational responding or enduring traits of personality that emerge over developmental time. Emotions play a critical role in the evolution of consciousness and the operations of all mental processes. Types of emotion relate differentially to types or levels of consciousness. Unbridled imagination and the ability for sympathetic regulation of empathy may represent both potential gains and losses from the evolution and ontogeny of emotion processes and consciousness. Unresolved issues include psychology's neglect of levels of consciousness that are distinct from access or reflective consciousness and use of the term "unconscious mind" as a dumpster for all mental processes that are considered unreportable. The relation of memes and the mirror neuron system to empathy, sympathy, and cultural influences on the development of socioemotional skills are unresolved issues destined to attract future research.

    Objective: To investigate the relationship between student engagement with the key elements of a flipped classroom approach (preparation and attendance), their attitudes to learning, including strategy development, and their performance on two types of examination questions (knowledge recall and providing rational predictions when faced with novel scenarios). Methods. This study correlated student engagement with the flipped classroom and student disposition to learning with student ability to solve novel scenarios in examinations. Results. Students who both prepared for and attended classes performed significantly better on examination questions that required analysis of novel scenarios compared to students who did not prepare and missed classes. However, there was no difference for both groups of students on examination questions that required knowledge and comprehension. Student motivation and use of strategies correlated with higher examination scores on questions requiring novel scenario analysis. Conclusion. There is a synergistic relationship between class preparation and attendance. The combination of preparation and attendance was positively correlated to assessment type; the relationship was apparent for questions requiring students to solve novel problems but not for questions requiring knowledge or comprehension.

    Full Text Available Understanding and managing coupled human and natural systems (CHANS is a central challenge of the 21st century, but more focus is needed to pursue the most important questions within this vast field given limited research capacity and funding. We present 40 important questions for CHANS research, identified through a two-part crowdsourcing exercise within the CHANS community. We solicited members of the International Network of Research on Coupled Human and Natural Systems (CHANS-Net to submit up to three questions that they considered transformative, receiving 540 questions from 207 respondents. After editing for clarity and consistency, we asked the network's members to each evaluate a random subset of 20 questions in importance on a scale from 1 (least important to 7 (extremely important. Questions on land use and agriculture topped the list, with a median importance ranking of 5.7, followed by questions of scale, climate change and energy, sustainability and development, adaptation and resilience, in addition to seven other categories. We identified 40 questions with a median importance of 6.0 or above, which we highlight as the current view of researchers active in the field as research questions to pursue in order to maximize impact on understanding and managing coupled human and natural systems for achieving sustainable development goals and addressing emerging global challenges.

    Although the 3 prime questions ("What did your doctor tell you the medication is for?" "How did your doctor tell you to take the medication?," and "What did your doctor tell you to expect?") have been recommended as a way to implement an interactive approach to patient's counseling in pharmacy, research examining how these questions are actually used in practice is relatively sparse. Qualitative approaches might assist to inform pertinent questions that might challenge prevailing paradigms. This commentary calls for a close look at how novice pharmacists in training manage these questions in real-life patient's consultations. These examples are aimed to provide preliminary observations about (1) how the prime questions in their original and modified forms are treated by pharmacists in training and patients, and (2) the interactional functions that the prime questions and similar questions may serve. Preliminary observations based on a conversation analysis of these examples show that the open-ended nature of the original prime questions sometimes leads to interactional problems such as delays in patients' responses and pharmacists' revision of the questions. Modified question formats that involve the use of specific knowledge expected to be possessed by a pharmacist, such as declarative questions and Q-word questions with concrete information, may lead to smoother interaction. Finally, questions about the purpose of the therapy may also be used to create opportunities to express empathy toward the patient or to shift the zone of expertise to the doctor. These initial findings suggest a more context sensitive and adaptive approach to communication in pharmacy. Copyright © 2013 Elsevier Inc. All rights reserved.

    Seroadaptive behaviors among men who have sex with men (MSM) are common, but ascertaining behavioral information is challenging in clinical settings. To address this, we developed a single seroadaptive behavior question. Men who have sex with men 18 years or older attending a sexually transmitted disease clinic in Seattle, WA, from 2013 to 2015, were eligible for this cross-sectional study. Respondents completed a comprehensive seroadaptive behavior questionnaire which included a single question that asked HIV-negative MSM to indicate which of 12 strategies they used in the past year to reduce their HIV risk. HIV testing was performed per routine clinical care. We used the κ statistic to examine agreement between the comprehensive questionnaire and the single question. We enrolled HIV-negative MSM at 3341 (55%) of 6105 eligible visits. The agreement between the full questionnaire and single question for 5 behaviors was fair to moderate (κ values of 0.34-0.59). From the single question, the most commonly reported behaviors were as follows: avoiding sex with HIV-positive (66%) or unknown-status (52%) men and using condoms with unknown-status partners (53%); 8% of men reported no seroadaptive behavior. Men tested newly HIV positive at 38 (1.4%) of 2741 visits. HIV test positivity for the most commonly reported behaviors ranged from 0.8% to 1.3%. Men reporting no seroadaptive strategy had a significantly higher HIV test positivity (3.5%) compared with men who reported at least 1 strategy (1.3%; P = 0.02). The single question performed relatively well against a comprehensive seroadaptive behaviors assessment and may be useful in clinical settings to identify men at greatest risk for HIV.

    2017-07-01

    Travel medicine needs are changing. New patterns of travel, including greater travel by individuals from emerging economies with different values in costs, risks and benefits, must be considered. This review aims to (1) highlight selected studies that have been published that address previously identified gaps in knowledge; (2) propose possible ways to consider questions regarding travel medicine practice for travelers from emerging economies, underscoring priorities for research focusing on these important populations; (3) highlight potential deficiencies in relevance of current international guidelines as they pertain to travelers from emerging economies; (4) frame research questions for travelers from emerging economies and (5) consider roles for ISTM in closing the gap. We reviewed past travel medicine research priorities published in 2010 to identify publications that responded to some research questions posed. We also reviewed CDC and WHO recommendations and assessed their applicability to travelers from emerging economies. Recent publications have responded to some research questions, but gaps remain and new questions have emerged. Re-framing of several key research questions is needed for travelers from emerging economies. A new challenge looms for traditional travel medicine fields to identify and attend to knowledge and guideline gaps, particularly to rethink questions regarding travel medicine to make them relevant for travelers from emerging economies. The International Society of Travel Medicine is well positioned to assist emerging economies assess their resources and needs, formulate research priorities and tailor the development of travel medicine into a framework aligned to their requirements. © International Society of Travel Medicine, 2017.

    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.

    2001-01-01

    This manuscript discusses the antimicrobial activity of fluoride and its in vivo importance in order to identify research questions. There is a lot of information on mechanisms by which fluoride may interfere with bacterial metabolism and dental plaque acidogenicity. The antimicrobial activity of fluoride products is enhanced when fluoride is associated with antimicrobial cations like Sn(2+) and amine. It is not clear whether the antimicrobial mechanisms of fluoride are operating in vivo or even to what extent antimicrobial activity can contribute to caries prevention. This latter question may be the most important one in research. Copyright 2001 S. Karger AG, Basel.

  9. Using mixed methods to identify and answer clinically relevant research questions.

    Shneerson, Catherine L; Gale, Nicola K

    2015-06-01

    The need for mixed methods research in answering health care questions is becoming increasingly recognized because of the complexity of factors that affect health outcomes. In this article, we argue for the value of using a qualitatively driven mixed method approach for identifying and answering clinically relevant research questions. This argument is illustrated by findings from a study on the self-management practices of cancer survivors and the exploration of one particular clinically relevant finding about higher uptake of self-management in cancer survivors who had received chemotherapy treatment compared with those who have not. A cross-sectional study generated findings that formed the basis for the qualitative study, by informing the purposive sampling strategy and generating new qualitative research questions. Using a quantitative research component to supplement a qualitative study can enhance the generalizability and clinical relevance of the findings and produce detailed, contextualized, and rich answers to research questions that would be unachievable through quantitative or qualitative methods alone. © The Author(s) 2015.

    Full Text Available Abstract Background Experts recommend formulating a structured research question to guide the research design. However, the basis for this recommendation has not been formally evaluated. The aim of this study was to examine if a structured research question using the PICOT (Population, Intervention, Comparator, Outcome, Time-frame format is associated with a better reporting quality of randomized controlled trials (RCTs. Methods We evaluated 89 RCTs reports published in three endocrinology journals in 2005 and 2006, the quality of reporting of which was assessed in a previous study. We examined whether the reports stated each of the five elements of a structured research question: population, intervention, comparator, outcome and time-frame. A PICOT score was created with a possible score between 0 and 5. Outcomes were: 1 a 14-point overall reporting quality score (OQS based on the Consolidated Standards for Reporting Trials; and 2 a 3-point key score (KS, based on allocation concealment, blinding and use of intention-to-treat analysis. We conducted multivariable regression analyses using generalized estimating equations to determine if a higher PICOT score or the use of a structured research question were independently associated with a better reporting quality. Journal of publication, funding source and sample size were identified as factors associated with OQS in our previous report on this dataset, and therefore included in the model. Results A higher PICOT score was independently associated with OQS (incidence rate ratio (IRR = 1.021, 95% CI: 1.012 to 1.029 and KS (IRR = 1.142, 95% CI: 1.079 to 1.210. A structured research question was present in 33.7% of the reports and it was associated with a better OQS (IRR = 1.095, 95% CI 1.059-1.132 and KS (IRR = 1.530, 95% CI 1.311-1.786. Conclusions Better framing of the research question using the PICOT format is independently associated with better overall reporting quality - although the effect

Specifically, the study compares the degree of answer completion and the level of user satisfaction for simple factual questions vs. more in‐depth subject‐based reference questions, and for ‘local’ (pertaining to a particular library and non‐local questions.Design – Content analysis of 415 transcripts of reference transactions, which were also compared to corresponding user satisfaction survey results.Setting – An online collaborative reference service offered by a large public library system (33 branch and regional locations. This service is part of the Metropolitan Cooperative Library System: a virtual reference consortium of U.S. libraries (public, academic, special, and corporate that provides 24/7 service.Subjects – Reference librarians from around the U.S. (49 different libraries, and users logging into the service via the public library system’s portal (primarily patrons of the 49 libraries. Method – Content analysis was used to evaluate virtual reference transcripts recorded between January and June, 2004. Reliability was enhanced through triangulation, with researchers comparing the content analysis of each transcript against the results of a voluntary exit survey. Of 1,387 transactions that occurred during the period of study, 420 users completed the survey and these formed the basis of the study, apart from 5 transactions that were omitted because the questions were incomprehensible. Questions were examined and assigned to five categories: “simple, factual questions; subject‐based research questions; resource access questions; circulation‐related questions; and local library information inquiries” (80‐81. Answers were classed as either “completely answered, partially answered or unanswered, referred, and problematic endings” (82. Lastly, user satisfaction was surveyed on three

    Full Text Available The study described here explored the differential effects of two learning strategies, self-explanation and reading questions and answers, on learning the computer programming language JavaScript. Students’ test performance and perceptions of effectiveness toward the two strategies were examined. An online interactive tutorial instruction implementing worked-examples and multimedia learning principles was developed for this study. Participants were 147 high school students (ages 14 to 18 of a computer introductory course in six periods which were randomly divided into two groups (n = 78; n = 69 of three periods each. The two groups alternated learning strategies to learn five lessons. Students’ prerequisite knowledge of XHTML and motivation to learn computer programming languages were measured before starting the tutorial. Students largely expressed their preference toward self-explanation over reading questions and answers. They thought self-explanation incurred much more work yet was more effective. However, the two learning strategies did not have differential effects on students’ test performance. The seeming discrepancy arising from students’ preferred strategy and their test performance was discussed in the areas of familiar versus new strategy, difficulty of learning materials and testing method, and experimental duration.

    Full Text Available In the field of knowledge in education, discussion about the treatment given to its definition as a field, investigative object and different possibilities theoretical-methodological, epistemological, was frequent in the last decades of the twentieth century. In this perspective, the aspects that relate to the process of construction and production of research in the field of education and knowledge of different theoretical and methodological possibilities deserve more theoretical and conceptual investment. Thus, this paper, from the literature, aims to present a brief discussion of the different conceptions of knowledge in the construction of research in the field of knowledge in education and two theoretical and methodological positions the practice of educational research. As a final consideration, the intention of this article is not to exhaust the issue in question, for there are many issues that permeate the practice of educational research.

    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.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a leading cause of morbidity, mortality and resource use worldwide. The goal of this official American Thoracic Society (ATS/European Respiratory Society (ERS Research Statement is to describe evidence related to diagnosis, assessment, and management; identify gaps in knowledge; and make recommendations for future research. It is not intended to provide clinical practice recommendations on COPD diagnosis and management. Clinicians, researchers and patient advocates with expertise in COPD were invited to participate. A literature search of Medline was performed, and studies deemed relevant were selected. The search was not a systematic review of the evidence. Existing evidence was appraised and summarised, and then salient knowledge gaps were identified. Recommendations for research that addresses important gaps in the evidence in all areas of COPD were formulated via discussion and consensus. Great strides have been made in the diagnosis, assessment and management of COPD, as well as understanding its pathogenesis. Despite this, many important questions remain unanswered. This ATS/ERS research statement highlights the types of research that leading clinicians, researchers and patient advocates believe will have the greatest impact on patient-centred outcomes.

    2005-12-01

    Community engagement is an on-going, arduous, and necessary process for developing effective health promotion programs. The challenges are amplified when the particular health issue or research question is not prominent in the consciousness of the targeted community. In this paper, we explore the community-based participatory research (CBPR) model as a means to negotiate a mutual agenda between communities and researchers. The paper is focused on the (perceived) need for cervical cancer screening in an under-resourced community in Cape Town, South Africa. Cervical cancer is a significant health problem in this community and elsewhere in South Africa. Unlike HIV-AIDS, however, many Black South Africans have not been educated about cervical cancer and the importance of obtaining screening. Many may not consider screening a priority in their lives. Our research included extensive consultations and informal interviews with diverse community and regional stakeholders. Following these, we conducted 27 focus groups and 106 demographic surveys with randomly selected youth, parents, local health care personnel, educators and school staff. Focus group data were summarized and analyzed cross-sectionally. Community stakeholders were involved throughout this research. Our consultations, interviews, and focus group data were key in identifying the concerns and priorities of the community. By engaging community stakeholders, we developed a research framework that incorporated the community's concerns and priorities, and stressed the intersecting roles of poverty, violence, and other cultural forces in shaping community members' health and wellbeing. Community members helped to refocus our research from cervical cancer to 'cervical health,' a concept that acknowledged the impact on women's bodies and lives of HIV-AIDS and STDs, sexual violence, poverty, and multiple social problems. We conclude that the research agenda and questions in community-based health research should not be

  4. Using the stable carbon and nitrogen isotope compositions of vervet monkeys (Chlorocebus pygerythrus to examine questions in ethnoprimatology.

    Directory of Open Access Journals (Sweden)

    James E Loudon

    Full Text Available This study seeks to understand how humans impact the dietary patterns of eight free-ranging vervet monkey (Chlorocebus pygerythrus groups in South Africa using stable isotope analysis. Vervets are omnivores that exploit a wide range of habitats including those that have been anthropogenically-disturbed. As humans encroach upon nonhuman primate landscapes, human-nonhuman primate interconnections become increasingly common, which has led to the rise of the field of ethnoprimatology. To date, many ethnoprimatological studies have examined human-nonhuman primate associations largely in qualitative terms. By using stable carbon (δ13C and nitrogen (δ15N isotope analysis, we use quantitative data to understand the degree to which humans impact vervet monkey dietary patterns. Based on initial behavioral observations we placed the eight groups into three categories of anthropogenic disturbance (low, mid, and high. Using δ13C and δ15N values we estimated the degree to which each group and each anthropogenically-disturbed category was consuming C4 plants (primarily sugar cane, corn, or processed foods incorporating these crops. δ13C values were significantly different between groups and categories of anthropogenic-disturbance. δ15N values were significantly different at the group level. The two vervet groups with the highest consumption of C4 plants inhabited small nature reserves, appeared to interact with humans only sporadically, and were initially placed in the mid level of anthropogenic-disturbance. However, further behavioral observations revealed that the high δ13C values exhibited by these groups were linked to previously unseen raiding of C4 crops. By revealing these cryptic feeding patterns, this study illustrates the utility of stable isotopes analysis for some ethnoprimatological questions.

    The cost of diapering an infant can place a significant financial strain on families living in poverty. Partnerships between diaper banks and home visiting programs for young families may offer an innovative solution to expanding the reach and impact of diaper banks in low-income communities. The purpose of this pilot study was to uncover preliminary information about the functions of diaper distribution through home visiting programs, and to inform future research and policy questions regarding diaper distribution to families in need. In this descriptive qualitative pilot study, semi-structured interviews were conducted with 6 home visitors from Minding the Baby ® (MTB), a home visiting intervention for young parents. MTB clinicians routinely distribute diapers in partnership with The Diaper Bank in Connecticut. We used directed content analysis to code and analyze interview transcripts. These preliminary findings indicate that partnerships between home visiting programs and diaper banks may benefit families by improving diaper access, reducing stigma, and fostering trusting relationships with home visitors. Home visiting program benefits including engagement or re-engagement with families may need to be balanced with potential effects on clinical and therapeutic relationships. Recommendations for next steps in research and related policy questions are discussed. © 2017 Wiley Periodicals, Inc.

    Participation in organized sport and recreational activities presents an innate risk for serious morbidity and mortality. Although death during sport or physical activity has many causes, advancements in sports medicine and evidence-based standards of care have allowed clinicians to prevent, recognize, and treat potentially fatal injuries more effectively. With the continual progress of research and technology, current standards of care are evolving to enhance patient outcomes. In this article, we provided 10 key questions related to the leading causes and treatment of sudden death in sport and physical activity, where future research will support safer participation for athletes and recreational enthusiasts. The current evidence indicates that most deaths can be avoided when proper strategies are in place to prevent occurrence or provide optimal care.

    Most people know that electric power lines, like the wiring in our homes, can cause serious electric shocks if we`re not careful. Many people also want to know whether the EMF (electric and magnetic fields) produced by power lines and other electrical devices affect our health. Although no adverse health effects of electric power EMF have been confirmed, there is continued scientific uncertainty about this issue. Research on EMF is ongoing throughout the world. The purpose of this booklet is to answer some common questions that the BPA (Bonneville Power Administration) receives about the possible effects of power lines on health. First, some basic electrical terms are defined, and electric and magnetic fields are debed. Next, answers are given to several questions about recent scientific studies. Some important information about electrical safety follows. We then describe how BPA is addressing public concerns about potential health effects of power lines. The last section tells you how to obtain more detailed information about the health and safety issues summarized in this booklet.

  10. How Tom Moon's research highlighted the question of glucose tolerance in carnivorous fish.

    2016-09-01

    Fifteen years ago, Tom Moon wrote a review on this journal in order to propose some explanations to the exacerbated glycaemic response after a glucose load or a carbohydrate meal intake observed in fish, the so-called intolerance to glucose. Before, but in most of cases after this paper, several laboratories worldwide started to make important efforts in order to better understand this strange phenotype observed in fish and that so far seemed to belong to diabetic humans only. Tom had been worked on fish metabolism for at least 30years when he proposed that mini-review and the paths opened by him in 2001 were followed by tens of fish researchers, making this paper a breaking point on the field. Fifteen years later, we propose not only to have a look to the answers given to the questions rose in that paper, but also to summarize how his career over all these years impacted the domain of glucose metabolism in fish. In the review, we will show how Tom Moon analysed at different levels (from genes up to the whole organism), using distinct experimental tools (cells, hormone or glucose injection, pumps, drugs) the questions of glucose metabolism, tolerance and nutrition in fish species.

    Full Text Available In the wake of globalisation, most universities are intensifying efforts to improve their overall performance in order to attract students and enhance chances of securing competitive funding from various sources. As part of these efforts, universities are striving to ensure that their postgraduate programmes meet nationally and internationally acceptable standards. Research projects conducted by students form a critical component of most postgraduate programmes and universities have put in place procedures meant to ensure that postgraduate research meets acceptable minimum standards. The procedures include setting minimum entry educational qualifications, supervision by qualified members of university academic staff, institutional evaluation of research proposals before the proposed research is embarked on, submission of progress reports by postgraduate students during the course of their programmes, and final examination of students theses, dissertations or research reports by internal as well as external examiners. In some instances, the examiners recommend outright rejection of the student's write-up if they consider the methodology used to be inappropriate to answer research questions of the project conducted. The implications of research methodological shortcomings which are identified at the final examination stage, even if the research proposals were evaluated and approved by appropriate university structures before commencement of the research projects, are discussed. As postgraduate programmes are meant to nurture a competent and resourceful workforce and future researchers, universities need to pay attention to the issue of research methodology and internal evaluation systems in order to minimise chances of compromising the quality of their postgraduate degree programmes.

    Directory of Open Access Journals (Sweden)

    David J. Cox, Steve Farrall and Barry Godfrey

    2007-04-01

    Full Text Available This article examines the concept of the persistent offender as a group within society, and the presumed impact of that discrete group upon society via a case study of offending in Crewe between 1880 and 1940. The findings of persistent offending in Crewe challenge the assumptions and prejudices of the period, about the links between unemployment and crime and the extent to which crime was an enduring ‘career’. There were no ‘hardened’ persistent offenders in the sample of the type envisaged by contemporary comment, though the role of drink in offending was sustained; and there was no clear ‘type’ of offender either. Examination of the life histories of a selection of offenders is shown to raise a number of interdisciplinary questions, challenging the assumptions of criminologists and legal scholars in relation to the role of legislation in the management of criminality, including the concept (of interest also to historians that reformation of the criminal was more achievable in the past than it is in the over-regulated present.

  17. The Neurobiology of Emotion-Cognition Interactions: Fundamental Questions and Strategies for Future Research

    Directory of Open Access Journals (Sweden)

    Hadas eOkon-Singer

    2015-02-01

    Full Text Available Recent years have witnessed the emergence of powerful new tools for assaying the brain and a remarkable acceleration of research focused on the interplay of emotion and cognition. This work has begun to yield new insights into fundamental questions about the nature of the mind and important clues about the origins of mental illness. In particular, this research demonstrates that stress, anxiety, and other kinds of emotion can profoundly influence key elements of cognition, including selective attention, working memory, and cognitive control. Often, this influence persists beyond the duration of transient emotional challenges, partially reflecting the slower molecular dynamics of catecholamine and hormonal neurochemistry. In turn, circuits involved in attention, executive control, and working memory contribute to the regulation of emotion. The distinction between the ‘emotional’ and the ‘cognitive’ brain is fuzzy and context-dependent. Indeed, there is compelling evidence that brain territories and psychological processes commonly associated with cognition, such as the dorsolateral prefrontal cortex and working memory, play a central role in emotion. Furthermore, putatively emotional and cognitive regions influence one another via a complex web of connections in ways that jointly contribute to adaptive and maladaptive behavior. This work demonstrates that emotion and cognition are deeply interwoven in the fabric of the brain, suggesting that widely held beliefs about the key constituents of ‘the emotional brain’ and ‘the cognitive brain’ are fundamentally flawed. We conclude by outlining several strategies for enhancing future research. Developing a deeper understanding of the emotional-cognitive brain is important, not just for understanding the mind but also for elucidating the root causes of its disorders.

    1995-01-01

    The requirements of the 1994 edition of CAN/CSA-N285.4 Periodic Inspection Standard, which address all known and postulated degradation mechanisms and introduce material surveillance demands, involve a growing need for improved nondestructive examination (NDE) methods and technologies. In order to have a proper technical support in its decisions concerning fuel channel inspections at Cernavoda NPP, the Romanian Power Authority (RENEL) initiated a Research Program regarding the nondestructive characterization of the fuel channels structural integrity. The paper presents the most significant results obtained on this Research Program: the ENDUS experimental system for Laboratory simulation of the fuel channel inspection, ultrasonic Rayleigh-Lamb waves technique for pressure tubes examination, phase analysis technique for near-surface flaws, influence of the metallurgical state of the pressure tube material on the eddy current defectoscopic signals, characterization of plastic deformation and fracture of zirconium alloys by acoustic emission.

    Comparing frequency of belief in reincarnation from different international survey projects (RAMP, EVS, ISSP) reveals differences of about 15 to 20 percent depending on the specific question format. If single binary questions are used, then belief in reincarnation is more often reported than if a forced-choice question is used which offers respondents alternatives to belief in reincarnation (e.g. resurrection). One possible explanation for this result is that respondents confuse reincarnation...

  2. Caribou Co-Management Needs From Research: Simple questions - Tricky answers

    1996-01-01

    Full Text Available Over the past decade, northern Canada has experienced a substantial increase in government reliance on advisory co-management organizations to manage caribou populations. Such groups, which are usually composed of government and local representatives, constantly require information about caribou upon which to base their recommendations. However, the standard 'scientific' approach to obtaining and presenting such information is in many cases no longer appropriate. In order to readjust the scientific focus on caribou research so that it is better attuned to co-management, this paper examines the role that research plays in the Canadian management of the Porcupine Caribou Herd as practiced by the Porcupine Caribou Management Board - a co-management advisory organization with a majority of native representatives.

  3. Examining Evident Interdisciplinarity Among Prides of Lion Researchers

    Directory of Open Access Journals (Sweden)

    2018-04-01

    Full Text Available Lions (Panthera leo have experienced dramatic population declines in recent decades and today, inhabit just a fraction of their historic range. The reasons behind these declines are many, but conflict with humans, principally motivated by lion depredation of livestock, is among the most influential. Recent calls within the scientific community have identified that wicked problems like these should be addressed using interdisciplinary approaches. Here we examined the extent to which human-lion conflict research has been interdisciplinary. We conducted an extensive review of the literature and uncovered 88 papers, published between 1990 and 2015, that assessed human-lion interaction and the ecology of lions exposed to anthropogenic disturbance. While human-lion conflict research experienced near-exponential growth (y = 8E-194e0.222x, R2 = 0.76 across this time period, the number of co-authors engaged in this research changed very little (x = 3.28, se = 0.19. Moreover, co-authors of this research tended to be affiliated with units from just three highly-related STEM disciplines (biology, wildlife management, and environmental science. Comparatively, co-authors affiliated with units in the humanities and social sciences occurred in <4% of all papers examined. Our analysis also presents a novel framework that positions human-lion conflict research as having not two dimensions, as has been commonly conceptualized, but five dimensions. These dimensions include not only the human and the lion dimensions, but also the livestock, wild prey, and environmental dimensions. None of the papers that we evaluated concurrently studied all five of these dimensions to determine their impact on human-lion conflict. Furthermore, despite the fact that human-lion conflict research was primarily developed by co-authors from STEM disciplines, the most common dimension evaluated was the human dimension which requires social science and humanities expertise. Our analysis

    To determine the performance and change over time when incorporating questions in the core competency domains of practice-based learning and improvement (PBLI), systems-based practice (SBP), and professionalism (PROF) into the national PM&R Self-Assessment Examination for Residents (SAER). Prospective, longitudinal analysis. The national Self-Assessment Examination for Residents (SAER) in Physical Medicine and Rehabilitation, which is administered annually. Approximately 1100 PM&R residents who take the examination annually. Inclusion of progressively more challenging questions in the core competency domains of PBLI, SBP, and PROF. Individual test item level of difficulty (P value) and discrimination (point biserial index). Compared with the overall test, questions in the subtopic areas of PBLI, SBP, and PROF were relatively easier and less discriminating (correlation of resident performance on these domains compared with that on the total test). These differences became smaller during the 3-year time period. The difficulty level of the questions in each of the subtopic domains was raised during the 3 year period to a level close to the overall exam. Discrimination of the test items improved or remained stable. This study demonstrates that, with careful item writing and review, multiple-choice items in the PBLI, SBP, and PROF domains can be successfully incorporated into an annual, national self-assessment examination for residents. The addition of these questions had value in assessing competency while not compromising the overall validity and reliability of the exam. It is yet to be determined if resident performance on these questions corresponds to performance on other measures of competency in the areas of PBLI, SBP, and PROF.

    The use of a mixed method research design raises many questions, especially regarding the paradigmatic position. With this paradigm, we may consider the mixed method design as the best way of answering a research question and the latter orients to one of the different subtypes of mixed method design. To illustrate the use of this kind of design, we propose a study such as conducted in nursing sciences. In this article, the challenges raised by the mixed method design, and the place of this type of research in nursing sciences is discussed.

    International Nuclear Information System (INIS)

    Muscara, J.

    1985-07-01

    Nondestructive examination/evaluation (NDE) of nuclear reactor components is required during fabrication, before service, and at regularly scheduled shutdowns for periodic inservice inspection (ISI). Any flaws produced during fabrication should be detected by the fabrication and preservice baseline examinations and components containing rejectable flaws should be repaired before the reactor enters service. The purpose of ISI is to ensure that any flaws which develop during service can be detected and evaluated and that unacceptable components are repaired or replaced to maintain safety, as well as to identify possible generic-type defects that may be present or developing in the remainder of the system or other similar systems so that timely corrective actions can be taken. The major thrusts of the research in ultrasonic testing for ISI are (1) to define the influence of inspection variables and procedures on inspection reliability and to determine the impact of inspection unreliability on system safety and (2) to study and evaluate improved techniques for reliable and accurate flaw detection and characterization. This research, therefore, has direct impact on evaluations of and improvements in reactor safety

    Directory of Open Access Journals (Sweden)

    Dick J Bierman

    Full Text Available We describe a method of quantifying the effect of Questionable Research Practices (QRPs on the results of meta-analyses. As an example we simulated a meta-analysis of a controversial telepathy protocol to assess the extent to which these experimental results could be explained by QRPs. Our simulations used the same numbers of studies and trials as the original meta-analysis and the frequencies with which various QRPs were applied in the simulated experiments were based on surveys of experimental psychologists. Results of both the meta-analysis and simulations were characterized by 4 metrics, two describing the trial and mean experiment hit rates (HR of around 31%, where 25% is expected by chance, one the correlation between sample-size and hit-rate, and one the complete P-value distribution of the database. A genetic algorithm optimized the parameters describing the QRPs, and the fitness of the simulated meta-analysis was defined as the sum of the squares of Z-scores for the 4 metrics. Assuming no anomalous effect a good fit to the empirical meta-analysis was found only by using QRPs with unrealistic parameter-values. Restricting the parameter space to ranges observed in studies of QRP occurrence, under the untested assumption that parapsychologists use comparable QRPs, the fit to the published Ganzfeld meta-analysis with no anomalous effect was poor. We allowed for a real anomalous effect, be it unidentified QRPs or a paranormal effect, where the HR ranged from 25% (chance to 31%. With an anomalous HR of 27% the fitness became F = 1.8 (p = 0.47 where F = 0 is a perfect fit. We conclude that the very significant probability cited by the Ganzfeld meta-analysis is likely inflated by QRPs, though results are still significant (p = 0.003 with QRPs. Our study demonstrates that quantitative simulations of QRPs can assess their impact. Since meta-analyses in general might be polluted by QRPs, this method has wide applicability outside the domain of

    Full Text Available Apart from the data on test reliability, the psychometric features of the TIMSS variables are not officially available. It is therefore not clear whether the TIMSS findings capture real educational trends. Being concerned with mathematics attitude, the aim of this research was to determine the psychometric values of a mathematics attitude scale derived from a student questionnaire, and, if these are appropriate, to examine the relation of mathematics attitude to gender and mathematics achievement, and search for gender differences in the applied mathematics attitude indicators. By using a sample of 89 seventh-grade students involved in a TIMSS 2003 pilot research, it revealed the following findings: (a the representativity reliability, homogeneity and validity of the applied attitude scale were acceptable, (b attitude to mathematics was related to mathematics achievement, (c gender differences in mathematics attitude were not found and (d gender differences in the applied indicators were only present for the statement "I need to do well in mathematics to get into the faculty of my choice" where males expressed a higher agreement than females.

    Full Text Available REICHERTZ' reflections on the development of qualitative research during the Berlin Meeting on Qualitative Research Methods in 2009 (http://www.berliner-methodentreffen.de/ have led to the following central questions: Are we facing the end of critical social research? Is this possible end correlated with an uncritical mass of young scientists? In their reply to the ancestors of qualitative research the present authors advocate the abolition of a bipolar thinking about the issues and support a hybrid turn, standing the test through a fundamentally open-minded, reflexive, and deconstructive researcher`s attitude. Using the example of ethnography and gender studies we show that there are indeed opportunities for the future of critical social research: This approach would take place beyond the slaves of market-controlled contract research and ahead of the characters of the eternal hall of fame of social research.

    2012-10-01

    Full Text Available In 1946 the American Institute of Architects established a Department of Education and Research (E&R, under architect Walter A. Taylor. The name given the new department signaled the importance of research for architecture, and the AIA’s intended leadership role in promoting research-based architectural practice. E&R developed research policies under an advisory board and in 1959 convened a conference on research for architecture, funded by the National Science Foundation. Butthe AIA never assumed full leadership in research for architecture: The scope of the project was beyond the means of either academia or the profession, and postwar research policies remained decentralized. Although E&R played a role in directing applied research, academic institutions provedmore able to assume leadership of basic research. This history illustrates the complexity of leadership in a field that bridges academia and professional practice, as well as the importance of multiple leadership roles.

    Background Qualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication. Design A quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research). Findings A 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, Pqualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research. Conclusions Despite an increase in the proportion of qualitative research in medical journals over a 10 year period, the proportion remains low. Journals' policies pertaining to qualitative research, as expressed by the

  7. A Critical Examination of My Qualitative Research Efforts in Turkey

    Full Text Available . Today, it is known and widely accepted that researchers must know the research paradigms and develop skills and non-dogmatic attitudes for conducting and evaluating studies in any methodology. Quantitative research methodology is more common while qualitative research is relatively new in Turkey. Researchers who have not developed sufficient knowledge and experiences in qualitative study would create nonevidence based and non-ethical research projects. This creates threats to the research community. In order to improve and be competent in any methodology, it is important to review and critically analyze the completed dissertations, thesis and the journal articles emerged from those research efforts. In this effort self-reflection of one’s own research effort is essential. In this paper as an experienced researcher the author shares her experiences in supervising theses and dissertations and conducting her own research projects in qualitative research methodology in the last 20 years in Turkey. In the light of the literature considering various aspects she discusses advantages and disadvantages conducting qualitative studies in Turkey. Considering the disadvantages, the author came up with the idea of keeping thinking positively, acting modestly, being patient, learning how to deal with the authority, learning how to deal with the exploiters, working hard, never giving up, focusing on the target, being assertive when necessary, and so keeping going in the scientific way.

    2013-01-01

    Nutrition research, ranging from molecular to population levels and all points along this spectrum, is exploring new frontiers as new technologies and societal changes create new possibilities and demands. This paper defines a set of frontiers at the population level that are being created by the increased societal recognition of the importance of nutrition; its connection to urgent health, social, and environmental problems; and the need for effective and sustainable solutions at the population level. The frontiers are defined in terms of why, what, who, and how we study at the population level and the disciplinary foundations for that research. The paper provides illustrations of research along some of these frontiers, an overarching framework for population nutrition research, and access to some of the literature from outside of nutrition that can enhance the intellectual coherence, practical utility, and societal benefit of population nutrition research. The frontiers defined in this paper build on earlier forward-looking efforts by the American Society for Nutrition and extend these efforts in significant ways. The American Society for Nutrition and its members can play pivotal roles in advancing these frontiers by addressing a number of well-recognized challenges associated with transdisciplinary and engaged research.

    Water quality has emerged as a fast-developing research area. Regular assessment of research activity is necessary for the successful R&D promotion. Water quality research work carried out in different countries increased over the years, and the USA ranked first in productivity while India stands in the seventh position in quantity and occupies the ninth position in quality of the research output. India observes a steady growth in the water quality research. Four thousand six hundred sixteen articles from India assessed from the aspect of citations received distributions of source countries, institutes, journals, impact factor, words in the title, author keywords. The qualitative and quantitative analysis identifies the contributions of the major institutions involved in research. Much of the country's water quality research is carried out by universities, public research institutions and science councils, whereas the contribution from Ministry of water resources not so significant. A considerable portion of Indian research is communicated through foreign journals, and the most active one is Environmental Monitoring and Assessment journal. Twenty-one percent of work is reported in journals published from India and around 7% ages in open access journals. The study highlights that international collaborative research resulted in high-quality papers. The authors meticulously analyse the published research works to gain a deeper understanding of focus areas through word cluster analyses on title words and keywords. When many papers deal with 'contamination', 'assessment' and 'treatment', enough studies done on 'water quality index', 'toxicity', considerable work is carried out in environmental, agricultural, industrial and health problems related to water quality. This detailed scientometric study from 1,09,766 research works from SCI-E during 1986-2015 plots the trends and identifies research hotspots for the benefit to scientists in the subject area.

    All too often, health policy and management decisions are made without making use of or consulting with the best available research evidence, which can lead to ineffective and inefficient health systems. One of the main actors that can ensure the use of evidence to inform policymaking is researchers. The objective of this study is to explore Israeli health systems and policy researchers' views and perceptions regarding the role of health systems and policy research (HSPR) in health policymaking and the barriers and facilitators to the use of evidence in the policymaking process. A survey of researchers who have conducted HSPR in Israel was developed. The survey consisted of a demographics section and closed questions, which focused on support both within the researchers' organisations and the broader environment for KTE activities, perceptions on the policymaking process, and the potential influencing factors on the process. The survey was sent to all health systems and policy researchers in Israel from academic institutions, hospital settings, government agencies, the four health insurance funds, and research institutes (n = 107). All responses were analyzed using descriptive statistics. For close-ended questions about level of agreement we combined together the two highest categories (agree or strongly agree) for analysis. Thirty-seven respondents participated in the survey. While many respondents felt that the use of HSPR may help raise awareness on policy issues, the majority of respondents felt that the actual use of HSPR was hindered for many reasons. While facilitators do exist to support the use of research evidence in policymaking, numerous barriers hinder the process such as challenges in government/provider relations, policymakers lacking the expertise for acquiring, assessing, and applying HSPR and priorities in the health system drawing attention away from HSPR. Furthermore, it is perceived by a majority of respondents that the health insurance funds

    Davidson, Anne Burgess

    Did the Third International Mathematics and Science Study (TIMSS) ask science teachers the right questions about their use of instructional time? Part I of this 2-part study used the TIMSS database to answer the question: Do 8th grade science teachers in the U.S., Czech Republic, Hungary, Japan, and Korea differ significantly in their perceived use of instructional time? Using the instructional activities in the TIMSS teacher question "How did the lesson proceed?" the teacher-reported times were analyzed using a repeated measures multivariate analysis. Significant differences were found between teacher-reported times in the U.S. and the other 4 TIMSS countries, whose 8th grade students outperformed U.S. students on TIMSS achievement tests. Post-hoc analysis indicated that TIMSS U.S. 8th grade science teachers report spending more time on homework in class, on group activities, and on lab activities, but less time on topic development, than TIMSS teachers from some or all of the other countries. Part II of this study further examined the question "How did the lesson proceed?" by videotaping 6 classes of 8th grade science in Alabama and Virginia and comparing observer coding of the video to the teachers' recalled descriptions of the same class. The difference between observer and teacher responses using TIMSS categories was not significant; however, 43% of the total variance was explained by whether the teacher or the observer reported the times for the instructional activities. The teachers also responded to questions from the NSF Local Systemic Change Through Teacher Enhancement K--8 Teacher Questionnaire to describe the same class. The difference found between the teacher and the observer coding was not significant, but the amount of variance explained by the data source (observer or teacher) dropped to 33% when using NSF student activity categories and to 26% when using NSF teacher activity categories. The conclusion of this study was that questionnaires to

    2012-07-01

    Considerable time and resources are invested in the ethics review process. We present qualitative data on how human research ethics committee members and health researchers perceive the role and function of the committee. The findings are based on interviews with 34 Australian ethics committee members and 54 health researchers. Although all participants agreed that the primary role of the ethics committee was to protect participants, there was disagreement regarding the additional roles undertaken by committees. Of particular concern were the perceptions from some ethics committee members and researchers that ethics committees were working to protect the institution's interests, as well as being overprotective toward research participants. This has the potential to lead to poor relations and mistrust between ethics committees and researchers.

    Traditional approaches to clinical research have, as yet, failed to provide effective treatments for vascular dementia (VaD). Novel approaches to collation and synthesis of data may allow for time and cost efficient hypothesis generating and testing. These approaches may have particular utility in helping us understand and treat a complex condition such as VaD. We present an overview of new uses for existing data to progress VaD research. The overview is the result of consultation with various stakeholders, focused literature review and learning from the group's experience of successful approaches to data repurposing. In particular, we benefitted from the expert discussion and input of delegates at the 9 th International Congress on Vascular Dementia (Ljubljana, 16-18 th October 2015). We agreed on key areas that could be of relevance to VaD research: systematic review of existing studies; individual patient level analyses of existing trials and cohorts and linking electronic health record data to other datasets. We illustrated each theme with a case-study of an existing project that has utilised this approach. There are many opportunities for the VaD research community to make better use of existing data. The volume of potentially available data is increasing and the opportunities for using these resources to progress the VaD research agenda are exciting. Of course, these approaches come with inherent limitations and biases, as bigger datasets are not necessarily better datasets and maintaining rigour and critical analysis will be key to optimising data use.

    Ecohydrology combines empiricism, data analytics, and the integration of models to characterize linkages between ecological and hydrological processes. A challenge for practitioners is determining which models best generalizes heterogeneity in hydrological behaviour, including water fluxes across spatial and temporal scales, integrating environmental and socio‐economic activities to determine best watershed management practices and data requirements. We conducted a literature review and synthesis of hydrologic, hydraulic, water quality, and ecological models designed for solving interdisciplinary questions. We reviewed 1,275 papers and identified 178 models that have the capacity to answer an array of research questions about ecohydrology or ecohydraulics. Of these models, 43 were commonly applied due to their versatility, accessibility, user‐friendliness, and excellent user‐support. Forty‐one of 43 reviewed models were linked to at least 1 other model especially: Water Quality Analysis Simulation Program (linked to 21 other models), Soil and Water Assessment Tool (19), and Hydrologic Engineering Center's River Analysis System (15). However, model integration was still relatively infrequent. There was substantial variation in model applications, possibly an artefact of the regional focus of research questions, simplicity of use, quality of user‐support efforts, or a limited understanding of model applicability. Simply increasing the interoperability of model platforms, transformation of models to user‐friendly forms, increasing user‐support, defining the reliability and risk associated with model results, and increasing awareness of model applicability may promote increased use of models across subdisciplines. Nonetheless, the current availability of models allows an array of interdisciplinary questions to be addressed, and model choice relates to several factors including research objective, model complexity, ability to link to other models, and

Put in its simplest terms, marketing is about promotion whilst market research is about understanding. Accordingly, data collected for market research purposes are used in a completely different way to that gathered for marketing, with research practices heavily regulated to ensure high ethical standards.Let’s begin with a definition of what, exactly, market research is. According to the ICC/ESOMAR International Code 2007 (a definition also adopted by the European Pharmaceutical Market Research Association, it is: «the systematic gathering and interpretation of information about individuals or organisations using the statistical and analytical methods and techniques of the applied social sciences to gain insight or support decision-making.

    Many traditional authentication techniques have been based on hardware solutions. Thus authentication of measurement system hardware has been considered in terms of physical inspection and destructive analysis. Software authentication has implied hash function analysis or authentication tools such as Rose. Continuity of knowledge is maintained through TIDs and cameras. Although there is ongoing progress improving all of these authentication methods, there has been little discussion of the human factors involved in authentication. Issues of non-traditional authentication include sleight-of-hand substitutions, monitor perception vs. reality, and visual diversions. Since monitor confidence in a measurement system depends on the product of their confidences in each authentication element, it is important to investigate all authentication techniques, including the human factors. This paper will present an initial effort to identify the most important problems that traditional authentication approaches in safeguards have not addressed and are especially relevant to arms control verification. This will include a survey of the literature and direct engagement with nontraditional experts in areas like psychology and human factors. Based on the identification of problem areas, potential research areas will be identified and a possible research agenda will be developed.

    Scotland's Centre of Expertise for Waters (CREW) delivers accessible research and expert opinion to support the Scottish Government and its delivery partners in the development and implementation of water policy. It was established in 2011 by the Scottish Government (Rural and Environmental Science and Analytical Services) in recognition of a gap in the provision of short term advice and research to policy (development and implementation). Key policy areas include the Water Framework Directive, Floods Directive, Drinking Water Directive, Habitats Directive and Scotland's Hydro Nation Strategy. CREW is unique in its demand-driven and free service for policy makers and practitioners, managing the engagement between scientists, policy makers and practitioners to work effectively across this interface. The users of CREW are the Scottish Government, Scottish Environment Protection Agency, Scottish Natural Heritage and Scottish Water. CREW has funded around 100 projects relating to water policy since its inception in 2011. Of these, a significant number relate to flood risk management policy. Based on a review of work to date, this poster will give an overview of these projects and a forward look at the challenges that remain. From learning from community led flood risk management to surface water flood forecasting for urban communities, links will be made between sustainable and traditional flood risk management while considering the perceptions of stakeholders to flood risk management. How can we deliver fully integrated flood risk management options? How policy makers, scientists and land managers can better work together will also be explored.

    2013-06-01

    The systems approach is arguably the dominant concept within accident analysis research. Viewing accidents as a result of uncontrolled system interactions, it forms the theoretical basis of various systemic accident analysis (SAA) models and methods. Despite the proposed benefits of SAA, such as an improved description of accident causation, evidence within the scientific literature suggests that these techniques are not being used in practice and that a research-practice gap exists. The aim of this study was to explore the issues stemming from research and practice which could hinder the awareness, adoption and usage of SAA. To achieve this, semi-structured interviews were conducted with 42 safety experts from ten countries and a variety of industries, including rail, aviation and maritime. This study suggests that the research-practice gap should be closed and efforts to bridge the gap should focus on ensuring that systemic methods meet the needs of practitioners and improving the communication of SAA research.

    Full Text Available This paper builds on existing theoretical and empirical studies in the areas of family business and entrepreneurship. It uses Dubin´s theory building framework to propose a model for conducting research of family businesses and its linkage to entrepreneurial activities in Mexico. This works starts by describing the concepts of family business and explains the importance that these definitions can have on the variables to be included in the research. After that, the paper explains how the concept of “familiness” relates to the essence definition of family business. Using the resource-based view (RBV, agency theory, and social capital theories we describe how social capital resources are the basis for building firm capabilities and competitive advantages that influence firm’s performances. Based on this perspective, a theoretical model, laws of interaction, a set of propositions and suggestions for further research are provided.

    2015-01-01

    Psychological research has increasingly recognized the importance of integrating temporal dynamics into its theories, and innovations in longitudinal designs and analyses have allowed such theories to be formalized and tested. However, psychological researchers may be relatively unequipped to analyze such data, given its many characteristics and the general complexities involved in longitudinal modeling. The current paper introduces time series analysis to psychological research, an analytic domain that has been essential for understanding and predicting the behavior of variables across many diverse fields. First, the characteristics of time series data are discussed. Second, different time series modeling techniques are surveyed that can address various topics of interest to psychological researchers, including describing the pattern of change in a variable, modeling seasonal effects, assessing the immediate and long-term impact of a salient event, and forecasting future values. To illustrate these methods, an illustrative example based on online job search behavior is used throughout the paper, and a software tutorial in R for these analyses is provided in the Supplementary Materials.

    Sun exposure has risks and benefits for health. Testing these associations requires tools for measuring sun exposure that are feasible and relevant to the time-course of the health outcome. Recent sun exposure, e.g. the last week, is best captured by dosimeters and sun diaries. These can also be used for medium-term sun exposure e.g. over several weeks, but incur a high participant burden. Self-reported data on "typical time outdoors" for working and non-working days, is less detailed and not influenced by day-to-day variation. Over a longer period, e.g. the lifetime, or for particular life stages, proxies of sun exposure, such as latitude of residence or ambient ultraviolet (UV) radiation levels (from satellites or ground-level monitoring) can be used, with additional detail provided by lifetime sun exposure calendars that include locations of residence, usual time outdoors, and detail of sunburn episodes. Objective measures of lifetime sun exposure include microtopography of sun-exposed skin (e.g. using silicone casts) or conjunctival UV autofluorescence. Potential modifiers of the association between sun exposure and the health outcome, such as clothing coverage and skin colour, may also need to be measured. We provide a systematic approach to selecting sun exposure measures for use in epidemiological health research. Copyright © 2015 Elsevier B.V. All rights reserved.

  16. On the Question of Methodological Support of Research on Relationships of Interpersonal Significance in Kindergarten Groups

    Full Text Available The paper focuses on the importance of in-depth research (in particular, employing an algorithm developed by M.Yu. Kondratyev for defining integral status of an individual on child-child interpersonal relationship in kindergarten groups. Although relationships with significant adults are by all means essential for preschool children, interpersonal relation- ships on the child-child level to a great extent shape the content of the social situation of development in general. Still, when it comes to revealing status and role position of the child in the structure of interpersonal relationships within the kindergarten group, there’s the challenge of defining informal intragroup structure of power in contact community (due to the age specifics. The paper suggests how this challenge may be addressed and provides a version of the technique suitable for preschoolers that helps overcome age restrictions implied by the original technique. Also, the paper reports on the outcomes of approbation of this version which proved its heuristic nature. For instance, the outcomes show a high degree of correlation between the results of kindergarten group members ranking in accordance with their influence upon peers carried out by teachers working in these groups.

  17. The Medical Anthropologist as the Patient: Developing Research Questions on Hospital Food in Japan through Auto-Ethnography

    2016-03-01

    Full Text Available I was an inpatient at a small maternity clinic in Japan in 2012–13 and found it impossible to separate the way I experienced medical care and my training as a medical anthropologist. As I was encouraged to eat and monitor my weight so that I would “grow” a healthy baby, I recalled how interviewees from my HIV/AIDS project described nourishing their bodies so they could fight disease. Because of my experience in the healthcare system in Japan, I ended up reframing my data to add questions about the role of hospital food in patient care. Meanwhile, I developed the social networks necessary to execute a new project, which I would later undertake. In this essay I argue that medical anthropologists working from a phenomenological perspective may regard their own bodies as assets rather than hindrances in research, and that because bodies are gendered, focusing on this facet of habitus can be particularly informative. I also illustrate how systematic reflection on personal experience in the field (autoethnography aids in the development of research questions and reframing data. Finally, I discuss how highlighting these steps in research methods courses can demystify the research process for students.

    Groups or institutions funding or conducting systematic reviews in health policy and systems research (HPSR) should prioritise topics according to the needs of policymakers and stakeholders. The aim of this study was to develop and validate a tool to prioritise questions for systematic reviews in HPSR. We developed the tool following a four-step approach consisting of (1) the definition of the purpose and scope of tool, (2) item generation and reduction, (3) testing for content and face validity, (4) and pilot testing of the tool. The research team involved international experts in HPSR, systematic review methodology and tool development, led by the Center for Systematic Reviews on Health Policy and Systems Research (SPARK). We followed an inclusive approach in determining the final selection of items to allow customisation to the user's needs. The purpose of the SPARK tool was to prioritise questions in HPSR in order to address them in systematic reviews. In the item generation and reduction phase, an extensive literature search yielded 40 relevant articles, which were reviewed by the research team to create a preliminary list of 19 candidate items for inclusion in the tool. As part of testing for content and face validity, input from international experts led to the refining, changing, merging and addition of new items, and to organisation of the tool into two modules. Following pilot testing, we finalised the tool, with 22 items organised in two modules - the first module including 13 items to be rated by policymakers and stakeholders, and the second including 9 items to be rated by systematic review teams. Users can customise the tool to their needs, by omitting items that may not be applicable to their settings. We also developed a user manual that provides guidance on how to use the SPARK tool, along with signaling questions. We have developed and conducted initial validation of the SPARK tool to prioritise questions for systematic reviews in HPSR, along with

  20. Examining the literacy component of science literacy: 25 years of language arts and science research

    Yore, Larry D.; Bisanz, Gay L.; Hand, Brian M.

    2003-06-01

    This review, written to celebrate the 25th anniversary of the International Journal of Science Education, revealed a period of changes in the theoretical views of the language arts, the perceived roles of language in science education, and the research approaches used to investigate oral and written language in science, science teaching, and learning. The early years were dominated by behavioralist and logico-mathematical interpretations of human learning and by reductionist research approaches, while the later years reflected an applied cognitive science and constructivist interpretations of learning and a wider array of research approaches that recognizes the holistic nature of teaching and learning. The early years focus on coding oral language into categories reflecting source of speech, functional purpose, level of question and response, reading research focused on the readability of textbooks using formulae and the reader's decoding skills, and writing research was not well documented since the advocates for writing in service of learning were grass roots practitioners and many science teachers were using writing as an evaluation technique. The advent of applied cognitive science and the constructivist perspectives ushered in interactive-constructive models of discourse, reading and writing that more clearly revealed the role of language in science and in science teaching and learning. A review of recent research revealed that the quantity and quality of oral interactions were low and unfocused in science classrooms; reading has expanded to consider comprehension strategies, metacognition, sources other than textbooks, and the design of inquiry environments for classrooms; and writing-to-learn science has focused on sequential writing tasks requiring transformation of ideas to enhance science learning. Several promising trends and future research directions flow from the synthesis of this 25-year period of examining the literacy component of science literacy

  1. Asking the right questions: Scoping studies in the commissioning of research on the organisation and delivery of health services

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available Abstract Scoping studies have been used across a range of disciplines for a wide variety of purposes. However, their value is increasingly limited by a lack of definition and clarity of purpose. The UK's Service Delivery and Organisation Research Programme (SDO has extensive experience of commissioning and using such studies; twenty four have now been completed. This review article has four objectives; to describe the nature of the scoping studies that have been commissioned by the SDO Programme; to consider the impact of and uses made of such studies; to provide definitions for the different elements that may constitute a scoping study; and to describe the lessons learnt by the SDO Programme in commissioning scoping studies. Scoping studies are imprecisely defined but usually consist of one or more discrete components; most commonly they are non-systematic reviews of the literature, but other important elements are literature mapping, conceptual mapping and policy mapping. Some scoping studies also involve consultations with stakeholders including the end users of research. Scoping studies have been used for a wide variety of purposes, although a common feature is to identify questions and topics for future research. The reports of scoping studies often have an impact that extends beyond informing research commissioners about future research areas; some have been published in peer reviewed journals, and others have been published in research summaries aimed at a broader audience of health service managers and policymakers. Key lessons from the SDO experience are the need to relate scoping studies to a particular health service context; the need for scoping teams to be multi-disciplinary and to be given enough time to integrate diverse findings; and the need for the research commissioners to be explicit not only about the aims of scoping studies but also about their intended uses. This necessitates regular contact between researchers and

    Questioned documents examined in a forensic laboratory sometimes contain signatures written with ballpoint pen inks; these signatures were examined to assess the feasibility of micro-attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy as a forensic tool. Micro-ATR FTIR spectra for signatures written with 63 ballpoint pens available commercially in Korea were obtained and used to construct an FTIR spectral database. A library-searching program was utilized to identify the manufacturer, blend, and model of each black ballpoint pen ink based upon their FTIR peak intensities, positions, and patterns in the spectral database. This FTIR technique was also successfully used in determining the sequence of homogeneous line intersections from the crossing lines of two ballpoint pen signatures. We have demonstrated with a set of sample documents that micro-ATR FTIR is a viable nondestructive analytical method that can be used to identify the origin of the ballpoint pen ink used to mark signatures. © 2014 American Academy of Forensic Sciences.

    To explore representations of the first pelvic examination (PE) among adolescents who had not yet had this examination and to identify their criteria for a positive experience of it. Qualitative study using semistructured interviews. Midi-Pyrénées and Auvergne in France. Adolescents aged 15 to 19 years who had never had a PE. Participants were recruited through snowball sampling and targeted sampling until data saturation was reached. Maximum variation was sought in the profiles of the study participants. Open-ended questions dealt with the interviewee's sources of information, knowledge of the PE, criteria for a positive PE experience, and representations of the PE itself. Verbatim transcripts were immediately subjected to longitudinal analysis with the context (researchers' notes) and key themes of the interview. Cross-sectional analysis was then performed. Many adolescents lack knowledge about the PE and believe that it is mandatory. According to study participants, the ideal PE would take place when they felt ready. They would be given adequate information in advance and the option of being accompanied by a friend or family member. They described the ideal examining room as warm, comfortable, and reassuring. The quality of their relationship with the examining physician would also affect their acceptance of this examination. An information session before the consultation for the PE would make it possible to reduce the patient's apprehension, improve her level of knowledge, and set the right tone for the upcoming PE, both for her and for the physician.

  4. Can simply answering research questions change behaviour? Systematic review and meta analyses of brief alcohol intervention trials.

    Directory of Open Access Journals (Sweden)

    Jim McCambridge

    Full Text Available Participant reports of their own behaviour are critical for the provision and evaluation of behavioural interventions. Recent developments in brief alcohol intervention trials provide an opportunity to evaluate longstanding concerns that answering questions on behaviour as part of research assessments may inadvertently influence it and produce bias. The study objective was to evaluate the size and nature of effects observed in randomized manipulations of the effects of answering questions on drinking behaviour in brief intervention trials.Multiple methods were used to identify primary studies. Between-group differences in total weekly alcohol consumption, quantity per drinking day and AUDIT scores were evaluated in random effects meta-analyses. Ten trials were included in this review, of which two did not provide findings for quantitative study, in which three outcomes were evaluated. Between-group differences were of the magnitude of 13.7 (-0.17 to 27.6 grams of alcohol per week (approximately 1.5 U.K. units or 1 standard U.S. drink and 1 point (0.1 to 1.9 in AUDIT score. There was no difference in quantity per drinking day.Answering questions on drinking in brief intervention trials appears to alter subsequent self-reported behaviour. This potentially generates bias by exposing non-intervention control groups to an integral component of the intervention. The effects of brief alcohol interventions may thus have been consistently under-estimated. These findings are relevant to evaluations of any interventions to alter behaviours which involve participant self-report.

  5. "We Don't See Things as They Are, We See Things as We Are": Questioning the "Outsider" in Polish Migration Research

    Directory of Open Access Journals (Sweden)

    Katherine Botterill

    2015-05-01

    Full Text Available This article offers a reflexive account of conducting research on Polish migration to Scotland from the perspective of the "outsider." The contribution argues for a revision to the insider/outsider dichotomy viewing it as inadequately nuanced in relation to the multiple intersectionalities performed through the research encounter. It is based on data collected from biographical-narrative interviews with Polish young people living in Edinburgh, Scotland. The article explores the interview encounter between an English researcher and Polish young people about the experience of EU mobility and argues that as migration narratives unfold the distinctions between the "researcher" and the "researched" blur. In particular, I focus on the intersections of gender, class and nationality to show how different positionalities are negotiated and confronted through reflexivity. The interview is a creative process involving co-construction of narratives through dialogue, embodied performances and non-cognitive associations that draw out the multiple intersectionalities of both parties. Through this process the binary of insider/outsider is called into question and this article examines the usefulness of this dichotomy as a framework for understanding the research relationship.

    There are disparities in the prevalence of childhood obesity for children from low-income and minority households. Mixed-methods studies that examine home environments in an in-depth manner are needed to identify potential mechanisms driving childhood obesity disparities that have not been examined in prior research. The Family Matters study aims to identify risk and protective factors for childhood obesity in low-income and minority households through a two-phased incremental, mixed-methods, and longitudinal approach. Individual, dyadic (i.e., parent/child; siblings), and familial factors that are associated with, or moderate associations with childhood obesity will be examined. Phase I includes in-home observations of diverse families (n=150; 25 each of African American, American Indian, Hispanic/Latino, Hmong, Somali, and White families). In-home observations include: (1) an interactive observational family task; (2) ecological momentary assessment of parent stress, mood, and parenting practices; (3) child and parent accelerometry; (4) three 24-hour child dietary recalls; (5) home food inventory; (6) built environment audit; (7) anthropometry on all family members; (8) an online survey; and (9) a parent interview. Phase I data will be used for analyses and to inform development of a culturally appropriate survey for Phase II. The survey will be administered at two time points to diverse parents (n=1200) of children ages 5-9. The main aim of the current paper is to describe the Family Matters complex study design and protocol and to report Phase I feasibility data for participant recruitment and study completion. Results from this comprehensive study will inform the development of culturally-tailored interventions to reduce childhood obesity disparities. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Assessing the Impact of De Novo Social Ties within Health Intervention Settings: New Questions for Health Behavior Intervention Research.

    Science.gov (United States)

    Tesdahl, Eric; Gesell, Sabina B

    2015-12-01

    Recent developments in the study of health and social networks have focused on linkages between health outcomes and naturally occurring social relations, such as friendship or kinship. Based on findings in this area, a new generation of health behavior intervention programs have been implemented that rely on the formation of new social relations among program participants. However, little is known about the qualities of these de novo social relations. We examined the social networks of 59 participants within a randomized controlled trial of an intervention designed to prevent excessive gestational weight gain. We employed exponential random graph modeling techniques to analyze supportive relationships formed between participants in the intervention arm, to detect unique effects of program participation on the likelihood of forming ties. Program participation had a positive effect on the likelihood of forming supportive social relations, however, in this particular timeframe we did not detect any additional effect of such relations on the health behaviors or outcomes of interest. Our findings raise two critical questions: do short-term group-level programs reliably lead to the formation of new social relations among participants; and do these relations have a unique effect on health outcomes relative to standard methods of health behavior intervention? © 2015 Wiley Periodicals, Inc.

    Understanding the referent of other's utterance by referring the contextual information helps in smooth communication. Although this pragmatic referential process can be observed even in infants, its underlying mechanism and relative abilities remain unclear. This study aimed to comprehend the background of the referential process by investigating whether the phonological loop affected the referent assignment. A total of 76 children (43 girls) aged 3-5 years participated in a reference assignment task in which an experimenter asked them to answer explicit (e.g., "What color is this?") and ambiguous (e.g., "What about this?") questions about colorful objects. The phonological loop capacity was measured by using the forward digit span task in which children were required to repeat the numbers as an experimenter uttered them. The results showed that the scores of the forward digit span task positively predicted correct response to explicit questions and part of the ambiguous questions. That is, the phonological loop capacity did not have effects on referent assignment in response to ambiguous questions that were asked after a topic shift of the explicit questions and thus required a backward reference to the preceding explicit questions to detect the intent of the current ambiguous questions. These results suggest that although the phonological loop capacity could overtly enhance the storage of verbal information, it does not seem to directly contribute to the pragmatic referential process, which might require further social cognitive processes.

    Full Text Available This study examined the relationship between graduate students’ research training environment, course experience, and research self-efficacy beliefs. The findings of the descriptive and regression analyses suggest that graduate students’ (n = 161 general research, quantitative, and qualitative research self-efficacy beliefs varied and that these beliefs were related to different aspects of the research training environment and course experiences, including their own personal research experiences. While course experience variables were significant predictors of quantitative and qualitative research self-efficacy, they were not predictive of general research methods self-efficacy. Also, while mentorship was a significant predictor of general research methods self-efficacy, it was not a significant predictor of quantitative and qualitative research self-efficacy. The implications of this study for research and graduate education are discussed.

    Full Text Available BACKGROUND: Meta-research can involve manual retrieval and evaluation of research, which is resource intensive. Creation of high throughput methods (e.g., search heuristics, crowdsourcing has improved feasibility of large meta-research questions, but possibly at the cost of accuracy. OBJECTIVE: To evaluate the use of double sampling combined with multiple imputation (DS+MI to address meta-research questions, using as an example adherence of PubMed entries to two simple Consolidated Standards of Reporting Trials (CONSORT guidelines for titles and abstracts. METHODS: For the DS large sample, we retrieved all PubMed entries satisfying the filters: RCT; human; abstract available; and English language (n=322,107. For the DS subsample, we randomly sampled 500 entries from the large sample. The large sample was evaluated with a lower rigor, higher throughput (RLOTHI method using search heuristics, while the subsample was evaluated using a higher rigor, lower throughput (RHITLO human rating method. Multiple imputation of the missing-completely-at-random RHITLO data for the large sample was informed by: RHITLO data from the subsample; RLOTHI data from the large sample; whether a study was an RCT; and country and year of publication. RESULTS: The RHITLO and RLOTHI methods in the subsample largely agreed (phi coefficients: title=1.00, abstract=0.92. Compliance with abstract and title criteria has increased over time, with non-US countries improving more rapidly. DS+MI logistic regression estimates were more precise than subsample estimates (e.g., 95% CI for change in title and abstract compliance by Year: subsample RHITLO 1.050-1.174 vs. DS+MI 1.082-1.151. As evidence of improved accuracy, DS+MI coefficient estimates were closer to RHITLO than the large sample RLOTHI. CONCLUSIONS: Our results support our hypothesis that DS+MI would result in improved precision and accuracy. This method is flexible and may provide a practical way to examine large corpora of

    2017-12-01

    Full Text Available Technology of the twenty-first century has transformed our ability to create, modify, store, and share digital media and, in so doing, has presented new possibilities for how social science research can be conducted and mobilized. This paper introduces the use of collaborative podcasting as a research method of critical inquiry and knowledge mobilization. Using a case study, we describe the methodological process that our transdisciplinary team engaged in to create the Water Dialogues podcast, a collaborative initiative stemming from a larger research project examining approaches to implementing Indigenous and Western knowledge in water research and management. We situate collaborative podcasting within an expanding field of collaborative and participatory media practice in social research, and consider how the method may align with and support research within a decolonizing agenda.

    Full Text Available Abstract Background Inconsistencies in research findings on the impact of the built environment on walking across the life course may be methodologically driven. Commonly used methods to define ‘neighbourhood’, from which built environment variables are measured, may not accurately represent the spatial extent to which the behaviour in question occurs. This paper aims to provide new methods for spatially defining ‘neighbourhood’ based on how people use their surrounding environment. Results Informed by Global Positioning Systems (GPS tracking data, several alternative neighbourhood delineation techniques were examined (i.e., variable width, convex hull and standard deviation buffers. Compared with traditionally used buffers (i.e., circular and polygon network, differences were found in built environment characteristics within the newly created ‘neighbourhoods’. Model fit statistics indicated that exposure measures derived from alternative buffering techniques provided a better fit when examining the relationship between land-use and walking for transport or leisure. Conclusions This research identifies how changes in the spatial extent from which built environment measures are derived may influence walking behaviour. Buffer size and orientation influences the relationship between built environment measures and walking for leisure in older adults. The use of GPS data proved suitable for re-examining operational definitions of neighbourhood.

    Science.gov (United States)

    Grabowicz, Marcin

    2018-04-01

    The Gram-negative outer membrane (OM) is a potent permeability barrier against antibiotics, limiting clinical options amid mounting rates of resistance. The Lol transport pathway delivers lipoproteins to the OM. All the OM assembly machines require one or more OM lipoprotein to function, making the Lol pathway central for all aspects of OM biogenesis. The Lol pathways of many medically important species clearly deviate from the Escherichia coli paradigm, perhaps with implications for efforts to develop novel antibiotics. Moreover, recent work reveals the existence of an undiscovered alternate route for bringing lipoproteins to the OM. Here, lipoprotein transport mechanisms, and the quality control systems that underpin them, is re-examined in context of their diversity. © 2018 WILEY Periodicals, Inc.

    Research replication, or repeating a study de novo, is the scientific standard for building evidence and identifying spurious results. While replication is ideal, it is often expensive and time consuming. Reproducibility, or reanalysis of data to verify published findings, is one proposed minimum alternative standard. While a lack of research reproducibility has been identified as a serious and prevalent problem in biomedical research and a few other fields, little work has been done to examine the reproducibility of public health research. We examined reproducibility in 6 studies from the public health services and systems research subfield of public health research. Following the methods described in each of the 6 papers, we computed the descriptive and inferential statistics for each study. We compared our results with the original study results and examined the percentage differences in descriptive statistics and differences in effect size, significance, and precision of inferential statistics. All project work was completed in 2017. We found consistency between original and reproduced results for each paper in at least 1 of the 4 areas examined. However, we also found some inconsistency. We identified incorrect transcription of results and omitting detail about data management and analyses as the primary contributors to the inconsistencies. Increasing reproducibility, or reanalysis of data to verify published results, can improve the quality of science. Researchers, journals, employers, and funders can all play a role in improving the reproducibility of science through several strategies including publishing data and statistical code, using guidelines to write clear and complete methods sections, conducting reproducibility reviews, and incentivizing reproducible science.

    There is growing awareness amongst healthcare planners, providers and researchers of the need to make better use of routinely collected health data by translating it into actionable information that improves efficiency of healthcare and patient outcomes. There is also increased acceptance of the importance of real world research that recruits patients representative of primary care populations and evaluates interventions realistically delivered by primary care professionals. The UNLOCK Group is an international collaboration of primary care researchers and practitioners from 15 countries. It has coordinated and shared datasets of diagnostic and prognostic variables for COPD and asthma to answer research questions meaningful to professionals working in primary care over a 6-year period. Over this time the UNLOCK Group has undertaken several studies using data from unselected primary care populations from diverse contexts to evaluate the burden of disease, multiple morbidities, treatment and follow-up. However, practical and structural constraints have hampered the UNLOCK Group's ability to translate research ideas into studies. This study explored the constraints, challenges and successes experienced by the UNLOCK Group and its participants' learning as researchers and primary care practitioners collaborating to answer primary care research questions. The study identified lessons for future studies and collaborations that require data sharing across borders. It also explored specific challenges to fostering the exchange of primary care data in comparison to other datasets such as public health, prescribing or hospital data and mechanisms that may be used to overcome these.

    Many studies have validated the psychometric properties of the Static-99, the most widely used measure of sexual offender recidivism risk. However much of this research relied on instrument coding completed by well-trained researchers. This study is the first to examine the interrater reliability (IRR) of the Static-99 between practitioners in the field and researchers. Using archival data from a sample of 1,973 formerly incarcerated sex offenders, field raters' scores on the Static-99 were compared with those of researchers. Overall, clinicians and researchers had excellent IRR on Static-99 total scores, with IRR coefficients ranging from "substantial" to "outstanding" for the individual 10 items of the scale. The most common causes of discrepancies were coding manual errors, followed by item subjectivity, inaccurate item scoring, and calculation errors. These results offer important data with regard to the frequency and perceived nature of scoring errors. © The Author(s) 2013.

  9. An examination of how women and underrepresented racial/ethnic minorities experience barriers in biomedical research and medical programs

    Science.gov (United States)

    Chakraverty, Devasmita

    Women in medicine and biomedical research often face challenges to their retention, promotion, and advancement to leadership positions (McPhillips et al., 2007); they take longer to advance their careers, tend to serve at less research-intensive institutions and have shorter tenures compared to their male colleagues (White, McDade, Yamagata, & Morahan, 2012). Additionally, Blacks and Hispanics are the two largest minority groups that are vastly underrepresented in medicine and biomedical research in the United States (AAMC, 2012; NSF, 2011). The purpose of this study is to examine specific barriers reported by students and post-degree professionals in the field through the following questions: 1. How do women who are either currently enrolled or graduated from biomedical research or medical programs define and make meaning of gender-roles as academic barriers? 2. How do underrepresented groups in medical schools and biomedical research institutions define and make meaning of the academic barriers they face and the challenges these barriers pose to their success as individuals in the program? These questions were qualitatively analyzed using 146 interviews from Project TrEMUR applying grounded theory. Reported gender-role barriers were explained using the "Condition-Process-Outcome" theoretical framework. About one-third of the females (across all three programs; majority White or Black between 25-35 years of age) reported gender-role barriers, mostly due to poor mentoring, time constraints, set expectations and institutional barriers. Certain barriers act as conditions, causing gender-role issues, and gender-role issues influence certain barriers that act as outcomes. Strategies to overcome barriers included interventions mostly at the institutional level (mentor support, proper specialty selection, selecting academia over medicine). Barrier analysis for the two largest URM groups indicated that, while Blacks most frequently reported racism, gender barriers

    Chung, Amy Z Q; Williamson, Ann; Shorrock, Steven T

    2014-01-01

    The research-practice gap is of concern in human factors/ergonomics (HF/E) as there is a belief that HF/E research may not be making an impact on practice in the 'real world'. A potential issue is what researchers and practitioners perceive as important in HF/E journal articles as a primary means of conveying research findings to practitioners. This study examined the characteristics that make scientific journal articles appeal to HF/E researchers and practitioners using a web-based survey. HF/E researchers and practitioners were more similar than expected in judgements of important attributes and the selection of articles. Both practitioners and researchers considered practical significance to be more important than theoretical significance, in direct contrast to professionals from a related discipline--psychology. Well-written articles were appreciated across disciplines. The results signal a strong interest in practical applications in HF/E, but a relative lack of focus on development of theories that should be the basis for practical applications.

    Research has only recently started to consider the importance and applicability of physical activity (PA) for people with bipolar disorder (BD). The aim of the current study is to highlight 10 pertinent PA research questions in people with BD. The International Organization of Physical Therapy in Mental Health executed a consultation with all National organizations (n=13) to identify the most salient questions to guide future research on PA in BD. We identified the following 10 questions: (1) What are the benefits of PA for people with BD? (2) What are the most prominent safety issues for PA prescription in BD? (3) What is the optimal PA prescription for people with BD? (4) What are the key barriers to PA among people with BD? (5) What are the most effective motivational strategies for ensuring PA adoption and maintenance in BD? (6) How do we translate PA research into community practice? (7) If one treatment goal is increased physical activity, what type of professionals are needed as part of a multidisciplinary team? (8) How do we incorporate PA as a vital sign in clinical practice? (9) How can we prevent sedentary behavior in BD? (10) What is the most appropriate PA assessment method? We did not consult people with BD. Addressing these questions is critical for developing evidence-based approaches for promoting and sustaining an active lifestyle in BD. Ultimately, achieving this will reduce the burden of cardiovascular disease and improve the quality of life of this population. Copyright © 2016 Elsevier B.V. All rights reserved.

    Nicholas V Olijnyk

    Full Text Available This study performed two phases of analysis to shed light on the performance and thematic evolution of China's quantum cryptography (QC research. First, large-scale research publication metadata derived from QC research published from 2001-2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China's QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China's performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China's performance indicators (i.e., Publication Frequency, citation score, H-index are growing. China's H-index (a normalized indicator has surpassed all other countries' over the last several years. The second phase of analysis shows how China's main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures; some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state, while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation. Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China's QC research themes, which can provide clarity into how QC technologies might take shape.

  19. Hyperactivity in anorexia nervosa: to warm or not to warm. That is the question (a translational research one).

    Science.gov (United States)

    Carrera, Olaia; Gutiérrez, Emilio

    2018-01-01

    In the Editorial 'Is the neglect of exercise in anorexia nervosa research a case of "running out" of ideas or do we need to take a "LEAP" of faith into the future?' these authors express their doubts concerning the suitability of keeping patients warm as a beneficial treatment option in managing excessive activity in anorexia nervosa (AN) patients. The case for warming as an adjunctive treatment for AN patients is based on strong experimental evidence gathered from research on animals with Activity-Based Anorexia (ABA). We posit that the beneficial effect of heat results, at least in part, from heat blocking the vicious cycle that hyperactivity plays on AN. Hyperactivity decreases caloric intake by interfering with feeding and increases energy expenditure through excess motor activity which in turn increases emaciation that further strengthens anorexic thinking.

    Educator-researcher partnerships are increasingly being used to improve the teaching of science. Chapter 1 provides a summary of the literature concerning partnerships, and examines the justification of qualitative methods in studying these relationships. It also justifies the use of Participatory Action Research (PAR). Empirically-based studies of educator-researcher partnership relationships are rare despite investments in their implementation by the National Science Foundation (NSF) and others. Chapter 2 describes a qualitative research project in which participants in an NSF GK-12 fellowship program were studied using informal observations, focus groups, personal interviews, and journals to identify and characterize the cultural factors that influenced the relationships between the educators and researchers. These factors were organized into ten critical axes encompassing a range of attitudes, behaviors, or values defined by two stereotypical extremes. These axes were: (1) Task Dictates Context vs. Context Dictates Task; (2) Introspection vs. Extroversion; (3) Internal vs. External Source of Success; (4) Prior Planning vs. Implementation Flexibility; (5) Flexible vs. Rigid Time Sense; (6) Focused Time vs. Multi-tasking; (7) Specific Details vs. General Ideas; (8) Critical Feedback vs. Encouragement; (9) Short Procedural vs. Long Content Repetition; and (10) Methods vs. Outcomes are Well Defined. Another ten important stereotypical characteristics, which did not fit the structure of an axis, were identified and characterized. The educator stereotypes were: (1) Rapport/Empathy; (2) Like Kids; (3) People Management; (4) Communication Skills; and (5) Entertaining. The researcher stereotypes were: (1) Community Collaboration; (2) Focus Intensity; (3) Persistent; (4) Pattern Seekers; and (5) Curiosity/Skeptical. Chapter 3 summarizes the research presented in chapter 2 into a practical guide for participants and administrators of educator-researcher partnerships

    The use of health data for public health, surveillance, quality improvement and research is crucial to improve health systems and health care. However, bodies responsible for privacy and ethics often limit access to routinely collected health data. Ethical approvals, issues around protecting privacy and data access are often dealt with by different layers of regulations, making approval processes appear disjointed. To create a comprehensive framework for defining the ethical and privacy status of a project and for providing guidance on data access. The framework comprises principles and related questions. The core of the framework will be built using standard terminology definitions such as ethics-related controlled vocabularies and regional directives. It is built in this way to reduce ambiguity between different definitions. The framework is extensible: principles can be retired or added to, as can their related questions. Responses to these questions should allow data processors to define ethical issues, privacy risk and other unintended consequences. The framework contains three steps: (1) identifying possible ethical and privacy principles relevant to the project; (2) providing ethics and privacy guidance questions that inform the type of approval needed; and (3) assessing case-specific ethics and privacy issues. The outputs from this process should inform whether the balance between public interests and privacy breach and any ethical considerations are tipped in favour of societal benefits. If they are then this should be the basis on which data access is permitted. Tightly linking ethical principles to governance and data access may help maintain public trust.

  5. Questions of trust in health research on social capital: what aspects of personal network social capital do they measure?

    2014-09-01

    Health research on personal social capital has often utilized measures of respondents' perceived trust of others as either a proxy for one's social capital in the absence of more focused measures or as a subjective component of social capital. Little empirical work has evaluated the validity of such practices. We test the construct validity of two trust measures used commonly in health research on social capital-generalized trust and trust of neighbors-with respect to measures of people's general network-, organization-, family-, friend-, and neighborhood-based social capital and the extent to which these two trust measures are associated with self-rated general health and mental health when social capital measures are included in the same models. Analyses of 2008 Canadian General Social Survey data (response rate 57.3%) indicate that generalized trust and trust of neighbors are both positively-yet modestly-associated with measures of several domains of network-based social capital. Both trust measures are positively associated with general and mental health, but these associations remain robust after adjusting for social capital measures. Our findings suggest that (a) trust is conceptually distinct from social capital, (b) trust measures are inadequate proxies for actual personal social networks, and (c) trust measures may only be capturing psychological aspects relevant to-but not indicative of-social capital. Though links between perceived trust and health deserve study, health research on social capital needs to utilize measures of respondents' actual social networks and their inherent resources.

    The importance of effective translation of health research findings into action has been well recognized, but there is evidence to suggest that the practice of knowledge translation (KT) among health researchers is still evolving. Compared to research user stakeholders, researchers (knowledge producers) have been under-studied in this context. The goals of this study were to understand the experiences of health researchers in practicing KT in Manitoba, Canada, and identify their support needs to sustain and increase their participation in KT. Qualitative semi-structured interviews were conducted with 26 researchers studying in biomedical; clinical; health systems and services; and social, cultural, environmental and population health research. Interview questions were open-ended and probed participants' understanding of KT, their experiences in practicing KT, barriers and facilitators to practicing KT, and their needs for KT practice support. KT was broadly conceptualized across participants. Participants described a range of KT practice experiences, most of which related to dissemination. Participants also expressed a number of negative emotions associated with the practice of KT. Many individual, logistical, and systemic or organizational barriers to practicing KT were identified, which included a lack of institutional support for KT in both academic and non-academic systems. Participants described the presence of good relationships with stakeholders as a critical facilitator for practicing KT. The most commonly identified needs for supporting KT practice were access to education and training, and access to resources to increase awareness and promotion of KT. While there were few major variations in response trends across most areas of health research, the responses of biomedical researchers suggested a unique KT context, reflected by distinct conceptualizations of KT (such as commercialization as a core component), experiences (including frustration and lack of

    Full Text Available First language (L1 transfer has been a key issue in the field of applied linguistics, second language acquisition (SLA, and language pedagogy for almost a century. Its importance, however, has been re-evaluated several times within the last few decades. The aim of this paper is to examine current research that has investigated the role of L1 transfer in second language (L2 writing. The paper begins by discussing the different views of L1 transfer and how they have changed over time and then reviews some of the major studies that have examined the role of L1 transfer both as a learning tool and as a communicative strategy in L2 writing. The paper concludes with a number of suggestions for L2 writing instruction and future research.

    Two decades of research on euthanasia in the Netherlands have resulted into clear insights in the frequency and characteristics of euthanasia and other medical end-of-life decisions in the Netherlands. These empirical studies have contributed to the quality of the public debate, and to the regulating and public control of euthanasia and physician-assisted suicide. No slippery slope seems to have occurred. Physicians seem to adhere to the criteria for due care in the large majority of cases. Further, it has been shown that the majority of physicians think that the euthanasia Act has improved their legal certainty and contributes to the carefulness of life-terminating acts. In 2005, eighty percent of the euthanasia cases were reported to the review committees. Thus, the transparency envisaged by the Act still does not extend to all cases. Unreported cases almost all involve the use of opioids, and are not considered to be euthanasia by physicians. More education and debate is needed to disentangle in these situations which acts should be regarded as euthanasia and which should not. Medical end-of-life decision-making is a crucial part of end-of-life care. It should therefore be given continuous attention in health care policy and medical training. Systematic periodic research is crucial for enhancing our understanding of end-of-life care in modern medicine, in which the pursuit of a good quality of dying is nowadays widely recognized as an important goal, in addition to the traditional goals such as curing diseases and prolonging life.

    The Romanian Institute for Nuclear Research (INR) has a set of nuclear facilities consisting of TRIGA 14 MW(th) materials testing reactor and LEPI (Romanian acronym for post-irradiation examination laboratory) which enable to investigate the behaviour of the nuclear fuel and materials under various irradiation conditions. The available techniques of post-irradiation examination (PIE) and purposes of PIE for CANDU reactor fuel are as follows. 1) Visual inspection and photography by periscope: To examine the surface condition such as deposits, corrosion etc. 2) Eddy current testing: To verify the cladding integrity. 3) Profilometry and length measurement performed both before and after irradiation: To measure the parameters which highlight the dimensional changes i.e. diameter, length, diametral and axial sheath deformation, circumferential sheath ridging height, bow and ovality. 4) Gamma scanning and Tomography: To determine the burnup, axial and radial fission products activity distribution and to check for flux peaking and loading homogeneity. 5) Puncture test: To measure the pressure, volume and composition of fission gas and the inner free volume. 6) Optical microscopy: To highlight the structural changes and hydriding, to examine the condition of the fuel-sheath interface and to measure the oxide thickness and Vickers microhardness. 7) Mass spectrometry: To measure the burnup. 8) Tensile testing: To check the mechanical properties. So far, non-destructive and destructive post-irradiation examinations have been performed on a significant number of CANDU fuel rods (about 100) manufactured by INR and irradiated to different power histories in the INR 14 MW(th) TRIGA reactor. These examinations have been performed as part of the Romanian research programme for the manufacturing, development and safety of the CANDU fuel. The paper describes the PIE techniques and some results. (Author)

    To evaluate the methodological adequacy of voice and laryngeal study designs published in speech-language pathology and otorhinolaryngology journals indexed for the ISI Web of Knowledge (ISI Web) and the MEDLINE database. A cross-sectional study conducted at the Universidade Federal de São Paulo (Federal University of São Paulo). Two Brazilian speech-language pathology and otorhinolaryngology journals (Pró-Fono and Revista Brasileira de Otorrinolaringologia) and two international speech-language pathology and otorhinolaryngology journals (Journal of Voice, Laryngoscope), all dated between 2000 and 2004, were hand-searched by specialists. Subsequently, voice and larynx publications were separated, and a speech-language pathologist and otorhinolaryngologist classified 374 articles from the four journals according to objective and study design. The predominant objective contained in the articles was that of primary diagnostic evaluation (27%), and the most frequent study design was case series (33.7%). A mere 7.8% of the studies were designed adequately with respect to the stated objectives. There was no statistical difference in the methodological quality of studies indexed for the ISI Web and the MEDLINE database. The studies published in both national journals, indexed for the MEDLINE database, and international journals, indexed for the ISI Web, demonstrate weak methodology, with research poorly designed to meet the proposed objectives. There is much scientific work to be done in order to decrease uncertainty in the field analysed.

    Full Text Available Objectives: This paper strives to develop a pragmatic view of the scope of practice and core characteristics of global health research (GHR by examining the activities of 14 Canadian-funded global health teams that were in the process of implementing research programs. Methods: Information was collected by a reflective exploration of team proposals and progress reports, a content analysis of the outputs from an all-team meeting and review of the literature. Results: Teams adopted equity-centered, problem-focused, systems-based approaches intended to find upstream determinants that could make people more resilient to social and ecological factors impacting their health. Long-term visions and time frames were needed to develop and solidify fully functional interdisciplinary, multinational, multicultural partnerships. The implementation of research into practice was a motivating factor for all teams, but to do this, they recognized the need for evidence-based advice on how to best do this. Traditional measures of biomedical research excellence were necessary but not sufficient to encompass views of excellence of team-based interdisciplinary research, which includes features like originality, coherence and cumulative contributions to fields of study, acceptance by peers and success in translating research into gains in health status. An innovative and nuanced approached to GHR ethics was needed to deal with some unique ethical issues because the needs for GHR were not adequately addressed by institutional biomedical research ethics boards. Core competencies for GHR researchers were a blend of those needed for health promotion, population health, international development, sustainable development, and systems science. Discussion: Developing acceptable and meaningful ways to evaluate the short-term contributions for GHR and forecast its long-term impacts is a strategic priority needed to defend decisions being made in GHR development.

    Hand eczema is an impacting cutaneous disease. Globally valid tools that help to diagnose hand and forearm eczema are required. To validate the questions to detect hand and/or forearm eczema included in the "Nordic Occupational Skin Questionnaire" (NOSQ-2002) in the Spanish language. A prospective pilot study was conducted with 80 employees of a cleaning company and a retrospective one involving 2,546 individuals. The responses were analysed for sensitivity, specificity and positive and negative predictive values. The final diagnosis according to the patients' hospital records, the specialty care records and the physical examination was taken as gold standard. The Dermatology Life Quality Index (DLQI) was also evaluated. Sensitivity and specificity, in a worst case scenario (WC) combining both questions, were 96.5% and 66.7%, respectively, and in a per protocol (PP) analysis, were 96.5% and 75.2%. The questions validated detected eczema effectively, making this tool suitable for use e.g. in multicentre epidemiological studies or clinical trials.

    Providing rigorous academic supplement to a professional development program for teachers, QUEST is a fusion of Drexel University's environmental science research department with Princeton University's Program in Teacher Preparation. Completed in the summers of 2012 (in partnership with Earthwatch) and 2013 in Barnegat Bay, New Jersey, QUEST's terrapin field research program enhances K-12 teachers' ecological knowledge, develops inquiry-based thinking in the classroom, and builds citizen science engagement. With a focus on quality question development and data analysis to answer questions, teachers are coached in developing, implementing, and presenting independent research projects on diamondback terrapin nesting ecology. As a result, teachers participating in QUEST's week long program bring a realistic example of science in action into their classrooms, helping to develop their own students' critical thinking skills. For teachers, this program provides training towards educating students on how to do real and imaginative science - subsequently sending students to university better prepared to engage in their own independent research. An essential component of the collaboration through QUEST, in addition to the teacher's experience during and after the summer institute, is the research data collected which supplements that of the Principal Investigator. In 2012, by documenting terrapin nest site predators, teachers gained valuable scientific experience, while Drexel acquired important ecological data which would have not been able to be collected otherwise. In 2013, teachers helped answer important questions about terrapin nesting success post Superstorm Sandy. In fact, the 2013 QUEST teachers are the first to visualize the frighteningly increased erosion of a primary terrapin nesting site due to Sandy; showing how most terrapin nests now lie in the bay, instead of safe on shore. Teachers comment that interacting with scientists in the field, and contributing to

    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.

    2016-01-01

    While considerable attention has been focused on understanding the myriad of ethical analysis in international research in low and middle income countries, new issues always arise that have not been anticipated in guidelines or studied extensively. The disruption of medical care arising as a direct result of political actions, including strikes, postelection violence and related activities, is one such issue that leaves physician-researchers struggling to manage often conflicting professional responsibilities. This paper discusses the ethical conflicts that arise for physician-researchers, particularly when disruption threatens the completion of a study or completion is possible but at the expense of not addressing unmet medical needs of patients. We review three pragmatic strategies and the ethical issues arising from each: not starting research, stopping research that has already started, and continuing research already initiated. We argue that during episodes of medical care disruption, research that has been started can be continued only if the ethical standards imposed at the beginning of the study can continue to be met; however, studies that have been approved but not yet started should not begin until the disruption has ended and ethical standards can again be assured.

    In this study, we used the topic of breast self-examination (BSE) to illustrate how content analysis of promotional texts (already in existence, in the process of being created, or both) can provide supplementary data to that derived from audience analysis. Specifically, we used content analysis to isolate messages in BSE pamphlets that are consistent with the variables of severity, susceptibility, response efficacy, and self-efficacy, identified by existing fear appeal research and supported by other persuasion research as critical to the construction of effective health promotion messages. We then used statistical analyses to describe the relation among these 4 message variables. Our findings suggested that BSE pamphlets contain an unbalanced proportion of threat to efficacy arguments. Additionally, the efficacy messages were substantively weak. We contrasted these messages against the relatively strong mammography arguments contained in these pamphlets. We then provided recommendations for formulating stronger persuasive arguments in BSE promotional materials.

    Austrian R and D activities in the HTR-field reach back almost to the beginning of this advanced reactor line. For more than 20 years post-irradiation examination (PIE) of HTR-fuel has been performed at the laboratories of the Austrian Research Centre Seibersdorf Ltd. (OEFZS) (formerly OESGAE) and a high degree of qualification has been achieved in the course of that time. Most of the PIE-work has been carried out by international cooperation on contract basis with the OECD-DRAGON-project and with KFA-Juelich (FRG). There has also been some collaboration with GA (USA), Belgonucleaire and others in the past. HTR-fuel elements contain the fissile and fertile materials in form of coated particles (CPs) which are embedded in a graphite matrix. Because of this special design it has been necessary from the very beginning of the PIE work up to now to develop new methods (i.e. fuel element disintegration methods, chlorine gas leach, single particle examination techniques...) as well as to adapt and improve already existing methods (i.e. gamma spectrometry, mass-spectrometry, optical methods...). The main interests on PIE-work at Seibersdorf are concentrated on particle performance, fission product distribution and the 'free' Uranium content (contamination and broken particles) of the fuel elements (fuel spheres or cylindrical compacts). A short compilation of the applied methods and of available instrumental facilities is given as follows: deconsolidation of fuel elements; equipment for electrochemical deconsolidation; examinations and measurements of graphite and electrolyte samples; examination of coated particles; single particle examinations

    Full Text Available Abstract: The present paper discusses an English teacher's questions in Reading classes at MAN Malang III. Types of questions, functions of teacher's questions, question levels and the strategies applied by the teacher were put as the research problems. Non-participant observa­tion was applied to collect the data with the researcher as the main in­strument aided by field-notes and a tape recorder. It was found that the distribution of the questions did not allow the students to talk longer and to think more analytically. Meanwhile, the strategies applied by the teacher helped the students to respond to the questions previously unanswered. The teacher is suggested to produce more open and refer­ential question as well as inference and evaluation questions as to give more chances for the students to think aloud more.

  3. Review of inservice inspection and nondestructive examination practices at DOE Category A test and research reactors

    In-service inspection (ISI) programs are used at commercial nuclear power plants for monitoring the pressure boundary integrity of various systems and components to ensure their continued safe operation. The Department of Energy (DOE) operates several test and research reactors. This report represents an evaluation of the ISI and nondestructive examination (NDE) practices at five DOE Category A (> 20 MW thermal) reactors as compared, where applicable, to the current ISI activities of commercial nuclear power facilities. The purpose of an inservice inspection (ISI) program is to establish regular surveillance of safety-related components to ensure their safe and reliable operation. The integrity of materials comprising these components is generally monitored by means of periodic nondestructive examinations (NDE), which, if appropriately performed, provide methods for identifying degradation that could render components unable to perform their intended safety functions. The reactors evaluated during this review were the Experimental Breeder Reactor 2 and the Fast Flux Test Facility (liquid-metal cooled plants), the Advanced Test Reactor and the High Flux Isotopes Reactor (light-water cooled reactors), and the High Flux Beam Reactor (a heavy-water cooled facility). Although these facilities are extremely diverse in design and operation, they all have less stored energy, smaller inventories of radionuclides, and generally, more remote locations than commercial reactors. However, all DOE test and research facilities contain components similar to those of commercial reactors for which continued integrity is important to maintain plant safety. 10 refs., 6 tabs

    Questions underpin all aspects of therapeutic assessment and intervention and are a vital component of the clinical process. Over recent years frameworks have started to be applied to obtain a greater understanding of questioning formats and processes. This paper examines the use of questions in cognitive therapy (CT). An overview of the main types of questions identified in the literature is presented. In addition, we examine a range of client and therapist characteristics that may impact on the questioning process. Asking questions in therapy is a complex, yet under-taught, skill. This paper provides a set of frameworks to assist in identifying helpful and unhelpful questioning skills. Thus the article has implications for further training and research.

    Problem-solving strategies learned by physics undergraduates should prepare them for real-world contexts as they transition from students to professionals. Yet, graduate students in physics-intensive research face problems that go beyond problem sets they experienced as undergraduates and are solved by different strategies than are typically learned in undergraduate coursework. This paper expands the notion of problem solving by characterizing the breadth of problems and problem-solving processes carried out by graduate students in physics-intensive research. We conducted semi-structured interviews with ten graduate students to determine the routine, difficult, and important problems they engage in and problem-solving strategies they found useful in their research. A qualitative typological analysis resulted in the creation of a three-dimensional framework: context, activity, and feature (that made the problem challenging). Problem contexts extended beyond theory and mathematics to include interactions with lab equipment, data, software, and people. Important and difficult contexts blended social and technical skills. Routine problem activities were typically well defined (e.g., troubleshooting), while difficult and important ones were more open ended and had multiple solution paths (e.g., evaluating options). In addition to broadening our understanding of problems faced by graduate students, our findings explore problem-solving strategies (e.g., breaking down problems, evaluating options, using test cases or approximations) and characteristics of successful problem solvers (e.g., initiative, persistence, and motivation). Our research provides evidence of the influence that problems students are exposed to have on the strategies they use and learn. Using this evidence, we have developed a preliminary framework for exploring problems from the solver's perspective. This framework will be examined and refined in future work.

Objetivo: evaluar la calidad de las preguntas del examen final ordinario de Morfofisiología Humana V. Métodos: fueron incluidos en esta investigación los 265 exámenes teóricos realizados por los estudiantes del segundo año en la Facultad de Medicina No. 2 de la Universidad de Ciencias Médicas de Santiago de Cuba, durante el curso 2011-2012, a los que se les calculó el índice de dificultad y el poder de discriminación en cada una de las 7 preguntas aplicadas. Resultados: las preguntas de respuesta alternativa, que evaluaban los contenidos sobre la sangre y el corazón, mostraron un índice de dificultad por debajo de 0,1 y un poder de discriminación inferior a 0,2, lo que hace necesaria su reformulación en próximos instrumentos evaluativos. Los valores más altos para ambos indicadores fueron 0,34 y 0,86, respectivamente, y correspondieron a una pregunta de selección múltiple sobre vasos sanguíneos y linfáticos, siguiéndoles en orden las preguntas de respuesta abierta.

    To produce a meta-study by completing a systematic review of qualitative research examining determinants of independent active free play in children. Following systematic electronic and manual searches and application of inclusion/exclusion criteria, 46 studies were retained and subjected to meta-method, meta-theory, and meta-data analyses, followed by a final meta-synthesis. Identified determinants of independent active free play were child characteristics (age, competence, and gender), parental restrictions (safety concerns and surveillance), neighborhood and physical environment (fewer children to play with, differences in preferences for play spaces between parents and children, accessibility and proximity, and maintenance), societal changes (reduced sense of community, good parenting ideal, changing roles of parents, privatization of playtime and play spaces), and policy issues (need to give children voice). An ecological model depicting these factors, and the relationships therein, was created. This comprehensive meta-study helps establish a knowledge base for children's independent active free play research by synthesizing a previously fragmented set of studies. Parents' perceived safety concerns are the primary barrier to children's active free play. These safety concerns are moderated by child-level factors (age, competence, gender) and broader social issues. Interventions should focus on community-level solutions that include children's perspectives. From a methods perspective, the reviewed studies used a range of data collection techniques, but methodological details were often inadequately reported. The theoretical sophistication of research in this area could be improved. To this end, the synthesis reported in this study provides a framework for guiding future research.

    Full Text Available Abstract Background The sequence of events in a behaviour change trial involves interactions between research participants and the trial process. Taking part in such a study has the potential to influence the behaviour of the participant, and if it does, this can engender bias in trial outcomes. Since participants’ experience has received scant attention, the aim of this study is thus to generate hypotheses about which aspects of the conduct of behaviour change trials might matter most to participants, and thus have potential to alter subsequent behaviours and bias trial outcomes Methods Twenty participants were opportunistically screened for a health compromising behaviour (unhealthy diet, lack of exercise, smoking or alcohol consumption and recruited if eligible. Semi structured face to face interviews were conducted, after going through the usual processes involved in trial recruitment, baseline assessment and randomisation. Participants were given information on the contents of an intervention or control condition in a behaviour change trial, which was not actually implemented. Three months later they returned to reflect on these experiences and whether they had any effect on their behaviour during the intervening period. Data from the latter interview were analysed thematically using a modified grounded theory approach. Results The early processes of trial participation raised awareness of unhealthy behaviours, although most reported having had only fleeting intentions to change their behaviour as a result of taking part in this study, in the absence of interventions. However, careful examination of the accounts revealed evidence of subtle research participation effects, which varied according to the health behaviour, and its perceived social acceptability. Participants’ relationships with the research study were viewed as somewhat important in stimulating thinking about whether and how to make lifestyle changes. Conclusion These

    Full Text Available “Socratic Method” is a way of teaching philosophical thinking and knowledge by asking questions which was used by antique period greek philosopher Socrates. Socrates was teaching knowledge to his followers by asking questions and the conversation between them was named “Socratic Dialogues”. In this meaning, no novel knowledge is taught to the individual but only what is formerly known is reminded and rediscovered. The form of socratic questioning which is used during the process of cognitive behavioral therapy is known as Guided Discovery. In this method it is aimed to make the client notice the piece of knowledge which he could notice but is not aware with a series of questions. Socratic method or guided discovery consists of several steps which are: Identifying the problem by listening to the client and making reflections, finding alternatives by examining and evaluating, reidentification by using the newly found information and questioning the old distorted belief and reaching to a conclusion and applying it. Question types used during these procedures are, questions for gaining information, questions revealing the meanings, questions revealing the beliefs, questions about behaviours during the similar past experiences, analyse questions and analytic synthesis questions. In order to make the patient feel understood it is important to be empathetic and summarising the problem during the interview. In this text, steps of Socratic Questioning-Guided Discovery will be reviewed with sample dialogues after eachstep. [JCBPR 2012; 1(1.000: 15-20

    This descriptive field study examines processes used to evaluate simulation for senior-level Bachelor of Science in Nursing (BSN) students in a capstone course, discusses challenges related to simulation evaluation, and reports the relationship between faculty evaluation of student performance and National Council Licensure Examination for Registered Nurses (NCLEX-RN) first-time passing rates. Researchers applied seven terms used to rank BSN student performance (n = 41, female, ages 22-24 years) in a senior-level capstone simulation. Faculty evaluation was correlated with students' NCLEX-RN outcomes. Students evaluated as "lacking confidence" and "flawed" were less likely to pass the NCLEX-RN on the first attempt. Faculty evaluation of capstone simulation performance provided additional evidence of student preparedness for practice in the RN role, as evidenced by the relationship between the faculty assessment and NCLEX-RN success. Simulation has been broadly accepted as a powerful educational tool that may also contribute to verification of student achievement of program outcomes and readiness for the RN role.

    Knowledge of the relationship between ambient air pollution levels measured at fixed monitoring stations and the actual exposure of the population is very limited. Indeed, there is rapidly growing evidence that fixed-station monitors do not provide adequate data for population exposure. This report examines available data for carbon monoxide (CO) and sulfur dioxide (SO/sub 2/) and presents a new analysis. Actual population exposure to CO appears to be consistently higher than expected from fixed-station data, while limited evidence suggests that exposures to SO/sub 2/ are lower. A reported general relationship between indoor and outdoor levels of SO/sub 2/ is not supported by the data. If air pollution represents a threat to public health, then more attention must be given to total population exposure to pollutants. A selective use of individual air pollution monitors that can be worn or carried appears to be required at some stage by any experimental design seeking to uncover the relation between air pollution exposure and health effects. Additionally, potential uses of individual monitoring in air pollution regulation are explored. Current status and research needs for individual air pollution monitors are examined and a first-order evaluation is given of the promise held by the candidate instrumentation technologies. A national program of support for the development of individual air pollution monitors is recommended.

    Tracking adolescent outcomes after inpatient hospitalization is important in informing clinical care for this age group, as inpatient care is one of the most expensive treatment modalities. This study examined 4 incentive strategies used to maintain adolescent participation in follow-up research (at 6, 12, and 18 mo) after their discharge from the hospital (N=267). A generalized estimation equation approach was taken to investigate whether different incentive strategies predicted adolescent completion of the follow-up assessments at each time point. Findings demonstrate that implementation of social worker contact significantly differed from other incentive strategies in increasing adolescent completion of follow-up assessments (Z=2.51, P=0.012) over the 3 time points, even when controlling for age and sex. Although these findings ultimately need to be confirmed through a randomized controlled study of incentive strategies, they provide preliminary support for the notion that relational incentives, such as maintaining contact with a member of the clinical team at the hospital, may be particularly important in promoting adolescent participation in outcomes research.

    A new era of stroke treatment may have begun with mechanical thrombectomy (MT) by fully deployed closed-cell self-expanding stents (stent-triever). Multiple case series and the first randomised controlled trials (RCTs) have now been published. More studies are under way involving large numbers of patients, which in turn has resulted in less strict ''pragmatic'' study protocols. Problems with current trials include a lack of standardisation in the conduct of the recanalisation procedure, the definition of primary endpoints such as the grade of arterial recanalisation and tissue reperfusion, and the post-surgical care provided. In Part 1 of this two part series, we outline the current situation and the major research questions. (orig.)

    Full Text Available Posing research questions is the central ability of the scientific thought. This article examines the ability of sixth grade children to pose researchable questions before and after a three months’ work on a didactic sequence based on the inquiry school model. According to their purpose, the questions asked by children, after reading a text, were classified into researchable questions -susceptible to be empirically explored-, questions about a cause, and questions on a piece of data. The results show that the amount and the type of questions the students were able to pose during the intervention changed, from most of questions on data or information, to most of researchable questions, subsequently, the importance of designing teaching approaches to foster this ability was proved.

    Hair and scalp problems are common. Unfortunately, many uncertainties exist around the most effective management and treatment strategies for these disorders. To identify uncertainties in hair-loss management, prevention, diagnosis and treatment that are important to both people with hair loss and healthcare professionals. A Hair Loss Priority Setting Partnership was established between patients, their carers and relatives, and healthcare professionals to identify the most important uncertainties in hair loss. The methodology of the James Lind Alliance was followed to ensure a balanced, inclusive and transparent process. In total, 2747 treatment uncertainties were submitted by 912 participants; following exclusions 884 uncertainties relating to hair loss (excluding alopecia areata) were analysed. Questions were combined into 'indicative uncertainties' following a structured format. A series of ranking exercises further reduced this list to a top 25 that was taken to a final prioritization workshop where the top 10 priorities were agreed. We present the top 10 research priorities for hair loss (excluding alopecia areata) to guide researchers and funding bodies to support studies important to both patients and clinicians. © 2017 British Association of Dermatologists.

    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 propose a hierarchy of methodological criteria to consider when determining whether a study provides sufficient information to answer the question of whether e-cigarettes can facilitate cigarette smoking cessation or reduction. A PubMed search to 1 February 2017 was conducted of all studies related to e-cigarettes and smoking cessation or reduction. Australia, Europe, Iran, Korea, New Zealand and the United States. 91 articles. Coders organized studies according to six proposed methodological criteria: (1) examines outcome of interest (cigarette abstinence or reduction), (2) assesses e-cigarette use for cessation as exposure of interest, (3) employs appropriate control/comparison groups, (4) ensures that measurement of exposure precedes the outcome, (5) evaluates dose and duration of the exposure and (6) evaluates the type and quality of the e-cigarette used. Twenty-four papers did not examine the outcomes of interest. Forty did not assess the specific reason for e-cigarette use as an exposure of interest. Twenty papers did not employ prospective study designs with appropriate comparison groups. The few observational studies meeting some of the criteria (duration, type, use for cessation) triangulated with findings from three randomized trials to suggest that e-cigarettes can help adult smokers quit or reduce cigarette smoking. Only a small proportion of studies seeking to address the effect of e-cigarettes on smoking cessation or reduction meet a set of proposed quality standards. Those that do are consistent with randomized controlled trial evidence in suggesting that e-cigarettes can help with smoking cessation or reduction. © 2017 Society for the Study of Addiction.

    2009-01-01

    Objective: The American Board of Psychiatry and Neurology (ABPN) has recently replaced the traditional, centralized oral examination with the locally administered Neurology Clinical Skills Examination (NEX). The ABPN postulated the experience with the NEX would be similar to the Mini-Clinical Evaluation Exercise, a reliable and valid assessment tool. The reliability and validity of the NEX has not been established. Methods: NEX encounters were videotaped at 4 neurology programs. Local faculty and ABPN examiners graded the encounters using 2 different evaluation forms: an ABPN form and one with a contracted rating scale. Some NEX encounters were purposely failed by residents. Cohen’s kappa and intraclass correlation coefficients (ICC) were calculated for local vs ABPN examiners. Results: Ninety-eight videotaped NEX encounters of 32 residents were evaluated by 20 local faculty evaluators and 18 ABPN examiners. The interrater reliability for a determination of pass vs fail for each encounter was poor (kappa 0.32; 95% confidence interval [CI] = 0.11, 0.53). ICC between local faculty and ABPN examiners for each performance rating on the ABPN NEX form was poor to moderate (ICC range 0.14-0.44), and did not improve with the contracted rating form (ICC range 0.09-0.36). ABPN examiners were more likely than local examiners to fail residents. Conclusions: There is poor interrater reliability between local faculty and American Board of Psychiatry and Neurology examiners. A bias was detected for favorable assessment locally, which is concerning for the validity of the examination. Further study is needed to assess whether training can improve interrater reliability and offset bias.

It was first used by in ancient times by the Greek philosopher Socrates who taught his followers by asking questions; these conversations between them are known as “Socratic dialogues”. In this methodology, no new knowledge is taught to the individual; rather, the individual is guided to remember and rediscover what was formerly known through this process. The main method used in cognitive therapy is guided discovery. There are various methods of guided discovery in cognitive therapy. The form of verbal exchange between the therapist and client which is used during the process of cognitive behavioral therapy is known as “socratic questioning”. In this method the goal is to make the client rediscover, with a series of questions, a piece of knowledge which he could otherwise know but is not presently conscious of. The Socratic Questioning consists of several steps, including: identifying the problem by listening to the client and making reflections, finding alternatives by examining and evaluating, reidentification by using the newly rediscovered information and questioning the old distorted belief, and reaching a new conclusion and applying it. Question types used during these procedures are: questions for collecting information, questions revealing meanings, questions revealing beliefs, questions about behaviours during similar past experiences, analytic questions and analytic synthesis questions. In order to make the patient feel understood, it is important to be empathetic and summarize the problem during the interview. In this text, steps of Socratic Questioning-Guided Discovery will be reviewed with sample dialogues provided for each step. [JCBPR 2015; 4(1.000: 47-53

  11. Answers to the questions about food irradiation. Concerning results of animal experiments in the specified integrated research. Data carrying a problem in human health were obtained?

    Ito, Hitoshi

    2007-01-01

    Experts of Food and Agriculture Organization (FAO)/ International Atomic Energy Agency (IAEA)/ World Health Organization (WHO) committee obtained their conclusion in 1980 that food irradiated with <10 kGy of radiation is safe for human health, which is now globally approved. However, in Japan, there have been still opposite opinions based on the doubt in the title on the safety of irradiated food. In this paper, the author answers those questions as he was a member to arrange the Research in the title for food irradiation. Described are data presentation and explanation about results of toxicity studies of diets added with irradiated materials of: weight reductions in rat ovary by irradiated potato (ip) in chronic studies, and in mouse testicle and ovary of F3 generation from the ancestor mice kept on diet with irradiated onion (io); bone malformation in mice by io; and reduction of body weight gain in female rats by ip and increase of mortality of male rats by ip. These are analyzed on the aspects of radiation dose-response, sustained tendency of results throughout the living period or generation, and apparent abnormality by other factors; and normal variation due to individual difference is pointed out to contribute to these findings. The safety test of irradiated food has been conducted valid not only in animal experiments but also other tests like genotoxicity and analysis of radiation-degraded products. (R.T.)

    Full Text Available This paper aims to explore whether some rhetorical questions contain certain linguistic elements or forms which would differentiate them from answer-eliciting and action-eliciting questions, and thereby hint at their rhetorical nature even outside the context. Namely, despite the fact that the same questions can be rhetorical in one context, and answer-eliciting in another, some of them are more likely to be associated with rhetorical or non-rhetorical use. The analysis is based on extensive data (over 1200 examples of rhetorical questions taken from 30 plays by two British and two American writers, and the results are expected to give an insight into whether we can talk about rhetorical questions or just a rhetorical use of questions.

    2016-06-01

    Palliative care research is relatively diverse and prioritizing research in this field is dependent on multiple factors such as complex ethical decisions in designing and conducting the research; access to participants who may be deemed "vulnerable" and an increasingly medically focused approach to care. The aim of this study was to inform organizational decision-making and policy development regarding future research priorities for a hospice service in New Zealand. A modified three-round Delphi technique was employed. Participants were drawn from one dedicated specialist palliative care service that delivers care in the community, day-care, hospice inpatient, aged residential care, and acute hospital palliative care service. A purposive sample included palliative care staff (n = 10, 18, 9, for rounds 1-3, respectively) volunteers (n = 10, 12, 11); and patients and family carers (n = 6, 8, for rounds 1 and 2). Patients and family carers were not involved in the third round. At final ranking of six research themes encompassing 23 research topics were identified by staff and volunteers. These were: symptom management; aged care; education; community; patient and family; and bereavement support and young people. Patients and family carers agreed on four themes, made up of 10 research topics. These were: decision-making, bereavement and loss, symptom management; and recognition of need and response of service. The study generated a rich set of research themes and specific research topics. The perspectives of staff and volunteers are significantly different from those of patients and family members, in spite of the recognition by all concerned that palliative care services work within a philosophy of patient-centered care. Open discussion of ideas has the potential to engage both staff and patients and carers in quality improvement initiatives, and to reinforce the value of research for patient care.

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

    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.

  10. Positive, negative, and bipolar questions: The effect of question polarity on ratings of text readability

    Directory of Open Access Journals (Sweden)

    Naomi Kamoen

    2013-12-01

    Full Text Available For decades, survey researchers have known that respondents give different answers to attitude questions worded positively (X is good. Agree-Disagree, negatively (X is bad. Agree-Disagree or on a bipolar scale (X is bad-good. This makes survey answers hard to interpret, especially since findings on exactly how the answers are affected are conflicting. In the current paper, we present twelve studies in which the effect of question polarity was measured for a set of thirteen contrastive adjectives. In each study, the same adjectives were used so the generalizability of wording effects across studies could be examined for each word pair. Results show that for five of the word pairs an effect of question wording can be generalized. The direction of these effects are largely consistent: respondents generally give the same answers to positive and bipolar questions, but they are more likely to disagree with negative questions than to agree with positive questions or to choose the positive side of the bipolar scale. In other words, respondents express their opinions more positively when the question is worded negatively. Even though answers to the three wording alternatives sometimes differ, results also show that reliable answers can be obtained with all three wording alternatives. So, for survey practice, these results suggest that all three wording alternatives may be used for attitude measurement.

    Vaino, Katrin; Holbrook, Jack; Rannikmäe, Miia

    2013-01-01

    The main goal of this study was to explore the role of collaborative action research in eliciting change in teacher beliefs. The beliefs were those of five chemistry teachers in implementing a new teaching approach, geared to enhancing students' scientific and technological literacy (STL). The teacher beliefs were analysed based on Ajzen's Theory of Planned Behaviour (2005) by looking at the teacher's (a) attitude towards implementing STL modules, (b) perceived subjective norms, and (c) behavioural control regarding the new teaching approach. After an introductory year, when teachers familiarised themselves with the new approach, a collaborative action research project was initiated in the second year of the study, helping teachers to minimise or overcome initially perceived constraints when implementing STL modules in their classroom. The processes of teacher change and the course of the project were investigated by teacher interviews, teacher informal commentaries, and meeting records. The formation of positive beliefs towards a STL approach increased continuously, although its extent and character varied depending on the teacher. The close cooperation, in the format of collaborative action research and especially through teacher group reflections and perceived collegial support, did support teacher professional development including change in their beliefs towards the new teaching approach. Additionally, positive feedback gained from other teachers through running a two-day in-service course in year three helped to strengthen all five teachers' existing beliefs towards the new approach. The current research demonstrated that perceived constraints, where identified, can be meaningfully addressed by teachers, through undertaking collaborative action research.

    When estimating the risks of oncogenesis and cancer mortality as a result of atomic bomb radiation exposure, medical X-ray doses received by the A-bomb survivors must also be estimated and considered. Using a phantom human, we estimated the X-ray doses received by A-bomb survivors during routine biennial medical examinations conducted at RERF as part of the long-term Adult Health Study (AHS), since these examinations may represent about 45 % of the survivors' total medical irradiations. Doses to the salivary glands, thyroid gland, lung, breast, stomach and colon were measured using thermoluminescent dosimeters. The results reported here will aid in estimating organ doses received by individual AHS participants. (author)

    Full Text Available The objective of this systematic review was to systematically review papers in the United States that examine current practices in privacy and security when telehealth technologies are used by healthcare providers. A literature search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P. PubMed, CINAHL and INSPEC from 2003 – 2016 were searched and returned 25,404 papers (after duplications were removed. Inclusion and exclusion criteria were strictly followed to examine title, abstract, and full text for 21 published papers which reported on privacy and security practices used by healthcare providers using telehealth.  Data on confidentiality, integrity, privacy, informed consent, access control, availability, retention, encryption, and authentication were all searched and retrieved from the papers examined. Papers were selected by two independent reviewers, first per inclusion/exclusion criteria and, where there was disagreement, a third reviewer was consulted. The percentage of agreement and Cohen’s kappa was 99.04% and 0.7331 respectively. The papers reviewed ranged from 2004 to 2016 and included several types of telehealth specialties. Sixty-seven percent were policy type studies, and 14 percent were survey/interview studies. There were no randomized controlled trials. Based upon the results, we conclude that it is necessary to have more studies with specific information about the use of privacy and security practices when using telehealth technologies as well as studies that examine patient and provider preferences on how data is kept private and secure during and after telehealth sessions.

    To evaluate how much the Addenbrooke's Cognitive Examination-revised (ACE-R) improves the estimate of cognitive ability from the Mini-Mental State Examination (MMSE) in people with Alzheimer disease (AD). We examined itemized data in people with AD who were on the Scottish Dementia Research Interest Register drawn from eight centres across Scotland, covering 75% of the Scottish population. ACE-R items that comprise the MMSE and those that did not (non-MMSE items) were summed separately. We residualized MMSE total on non-MMSE total and vice versa to derive a measure of the variance unique to each. Five hundred and one (258 male, 243 female) participants, mean age 75.7 (range 52-94) years were on the register, of whom 329 (160 men, 169 women) had AD. Of those with AD, 309 had a mean MMSE of 20.5 and mean ACE-R of 57.5 measured with Pearson r = 0.92 between MMSE and ACE-R totals, and the regression equation ACE-R score = 3.0 × MMSE - 4.1. The unique non-MMSE items score correlated with ACE-R total r = 0.40 (16% of ACE-R variance). The ACE-R and MMSE total scores are highly correlated. In this clinical sample of people with established AD, for an MMSE score of 24, the predicted ACE-R score was 67.9 with 95% confidence intervals of 61.6-75.4. The extra non-MMSE ACE-R items improve estimates of cognitive ability by 16%. Copyright © 2012 John Wiley & Sons, Ltd.

    2013-12-01

    To review the extant literature on HIV criminal laws, and to determine the impact of these laws on public health practice. The available research on this topic was obtained and reviewed. The extant literature addressed three main topics: people's awareness of HIV criminal laws; people's perceptions of HIV criminal laws; and the potential effects of HIV criminal laws on people's sexual, HIV-status disclosure and healthcare-seeking practices. Within these categories, the literature demonstrated a high level of awareness of HIV criminal laws, but a poor comprehension of these laws. For perceptions, on the whole, the quantitative research identified support for, while the qualitative literature indicated opposition to, these laws. Lastly, the behavioural effects of HIV criminal laws appear to be complex and non-linear. A review of the extant literature from a public health perspective leads to the conclusion that HIV criminal laws undermine public health.

    This study aims to evaluate the potential risks submitted by the incidents in nuclear research reactors. For its development, two databases of the International Atomic Energy Agency, IAEA, were used, the Incident Report System for Research Reactor and Research Reactor Data Base. For this type of assessment was used the Probabilistic Safety Analysis (PSA), within a confidence level of 90% and the Deterministic Probability Analysis (DPA). To obtain the results of calculations of probabilities for PSA, were used the theory and equations in the paper IAEA TECDOC - 636. The development of the calculations of probabilities for PSA was used the program Scilab version 5.1.1, free access, executable on Windows and Linux platforms. A specific program to get the results of probability was developed within the main program Scilab 5.1.1., for two distributions Fischer and Chi-square, both with the confidence level of 90%. Using the Sordi equations and Origin 6.0 program, were obtained the maximum admissible doses related to satisfy the risk limits established by the International Commission on Radiological Protection, ICRP, and were also obtained these maximum doses graphically (figure 1) resulting from the calculations of probabilities x maximum admissible doses. It was found that the reliability of the results of probability is related to the operational experience (reactor x year and fractions) and that the larger it is, greater the confidence in the outcome. Finally, a suggested list of future work to complement this paper was gathered. (author)

    Science and engineering research has becoming an increasingly international phenomenon. Traditional bibliometric studies have not captured the evolution of collaborative partnerships between countries, particularly in emerging technologies such as stem cell science, in which an immense amount of investment has been made in the past decade. Analyzing over 2,800 articles from the top journals that include stem cell research in their publications, this study demonstrates the globalization of stem cell science. From 2000 to 2010, international collaborations increased from 20.9% to 36% of all stem cell publications analyzed. The United States remains the most prolific and the most dominant country in the field in terms of publications in high impact journals. But Asian countries, particularly China are steadily gaining ground. Exhibiting the largest relative growth, the percent of Chinese-authored stem cell papers grew more than ten-fold, while the percent of Chinese-authored international papers increased over seven times from 2000 to 2010. And while the percent of total stem cell publications exhibited modest growth for European countries, the percent of international publications increased more substantially, particularly in the United Kingdom. Overall, the data indicated that traditional networks of collaboration extant in 2000 still predominate in stem cell science. Although more nations are becoming involved in international collaborations and undertaking stem cell research, many of these efforts, with the exception of those in certain Asian countries, have yet to translate into publications in high impact journals.

    2009-05-01

    Full Text Available The paper presents a rubric to help evaluate the quality of research projects. The rubric was applied in a competition across a variety of disciplines during a two-day research symposium at one institution in the southwest region of the United States of America. It was collaboratively designed by a faculty committee at the institution and was administered to 204 undergraduate, master, and doctoral oral presentations by approximately 167 different evaluators. No training or norming of the rubric was given to 147 of the evaluators prior to the competition. The findings of the inter-rater reliability analysis reveal substantial agreement among the judges, which contradicts literature describing the fact that formal norming must occur prior to seeing substantial levels of inter-rater reliability. By presenting the rubric along with the methodology used in its design and evaluation, it is hoped that others will find this to be a useful tool for evaluating documents and for teaching research methods.

  10. Low-enriched research reactor fuel: Post-Irradiation Examinations at SCK-CEN

    Generally, research and test reactors are fuelled with fuel plates instead of pins. In most cases in the past, these plates consisted of high enriched (higher than 95 percent 235 U) UAl 3 powder mixed with a pure Al matrix (called the meat) in between two aluminium alloy plates (the cladding). These plates are then assembled in fuel elements of different designs to fit the needs of the various reactors. Since the 1970's, efforts have been going on to replace the high-enriched, low-density UAl 3 fuel with high-density, low enriched ( 235 U) replacements. This search is driven by the attempt to reduce the civil use of high-enriched materials because of proliferation risks and terrorist threats. American initiatives, such as the Global Threat Reduction Initiative and the Reduced Enrichment for Research and Test Reactors program have triggered the development of reliable low-enriched fuel types for these reactors, which can replace the high enriched ones without loss of performance. Most success has been obtained with U 3 Si 2 fuel, which is currently used in many research reactors in the world. However, efforts to search for a better replacement have continued and are currently directed towards the U-Mo alloy fuel (7-10 weight percent Mo)

    Research examining the utilization of evidence-based practice (EBP) specifically among rehabilitation clinicians is limited. The objective of this study was to examine how various rehabilitative clinicians including physical therapists, occupational therapists, rehabilitation counselors, and physiatrists are gaining access to literature and whether they are able to implement the available research into practice. A total of 21 total clinicians were interviewed via telephone. Using NVivo, a qualitative analysis of the responses was performed. There were similarities found with respect to the information-seeking behaviors and translation of research across the different clinician types. Lack of time was reported to be a barrier for both access to literature and implementation of research across all clinician types. The majority of clinicians who reported having difficulty with utilizing the published literature indicated that the literature was not applicable to their practice, the research was not specific enough to be put into practice, or the research found was too outdated to be relevant. In addition, having a supportive work environment aided in the search and utilization of research through providing resources central to assisting clinicians in gaining access to health information. Our study identified several barriers that affect EBP for rehabilitation clinicians. The findings suggest the need for researchers to ensure that their work is applicable and specific to clinical practice for implementation to occur.

  12. Examining “Elite” Power Dynamics in Informant–Research Relations and Its Impact on Ethnographic Data Construction

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available This article explores how power dynamics between informants and field researchers shape ethnographic data construction, drawing on fieldwork at a pharmaceutical company. Pharmaceutical companies are considered elite settings, and often assumed to be powerful in relation to the researcher and dominating the data construction. However, such a view conceptualizes power in terms of fixed categories, in which there is a superior and subordinate position. We reconsider the impact of elite informants in the light of a constructivist, interactionist view on power, in which power is dynamic and not necessarily entailing domination. We answer the following research questions: (1 How can we observe power dynamics, as conceptualized in a constructionist and interaction orientation, in ethnographic research? and (2 How can we reflect on what these power dynamics mean for data construction, based on our experiences in elite settings? To do so, we make use of discursive and interactional analytic methods and propose three levels of analysis: (1 the level of conversation, (2 the level of ethnography, and (3 the level of the organization in society. They respectively shed light on power in relation to (1 what is said and how, (2 the meanings attached to the ethnographic events, and (3 the meaning of the ethnography in relation to the discourses on the organization in society. With this article, we aim to provide researchers with a methodological tool to approach and to reflect on the significance of power relations in the context of ethnography and interviewing and its impact on data construction.

    Systematic studies on art objects using instrumental neutron activation analysis and neutron autoradiography have been carried out in the Institute of Nuclear Chemistry and Technology in collaboration with the Faculty of Art Conservation and Restoration of the Academy of Fine Arts in Cracow, as well as with other Academies of Fine Arts and museums in Poland. A number of essential data on the concentration of trace elements particularly in chalk grounds and pigments (such as lead white, lead-tin yellow, smalt), Chinese porcelain, Thai ceramics, as well as in the clay fillings of sarcophagi of Egyptian mummies was accumulated. The above mentioned examination of art objects prior to their conservation helps to determine precisely the materials used in the process of creating art objects, as well as to identify the approximate place of origin of particular materials.

    Full Text Available AIM: To study the keratoconus(KCNand subclinical KCN in patients with astigmatism ≥2D by Pentacam anterior segment analyzer. METHODS: Two hundred and one eyes in 107 patients with astigmatism ≥2D were included in this study. All patients underwent optometry, visual acuity, corrected visual acuity, slit lamp biomicroscopy, fundus examination, traditional corneal topography and examination with Pentacam. Changes of several parameters were observed including K1(horizontal central curvature within the scope with diameter of 3mm, K2(vertical central curvature within the scope with diameter of 3mm; Kmax(the maximum anterior corneal refractive power, corneal astigmatism(CYL, MinPachy(the thickness at the thinnest area of cornea, index of surface variation(ISV, index of vertical asymmetry(IVA, keratoconus index(KI, height of anterior corneal surface(AEand height of posterior corneal surface(PE, etc. ROC curve was made. Cutoff value and the sensitive index of each group were compared. Mann-Whitney U test was used for analysis of several parameters obtained from Pentacam. ROC curve was analyzed to determine the best diagnosis cutoff value. RESULTS: Mean age of the study population was 25.7±6.6 years old. Kmax, IVA, KI, AE and PE of the clinical and subclinical group were significantly higher than those of the astigmatism group, while the thickness at the thinnest area of cornea in clinical and subclinical group was lower than that of the astigmatism group(PCONCLUSION: The current study shows that subjects with 2D or more of astigmatism, even some of them have normal vision, should undergo corneal topography screening. Pentacam may provide more accurate information about anterior and posterior corneal anatomy especially for the height of posterior corneal surface, which plays an important role in screening of subclinical KCN.

    Faucher, Mary Ann; Garner, Shelby L

    2015-11-01

    The purpose of this manuscript is to compare methods and thematic representations of the challenges and supports of family caregivers identified with photovoice methodology contrasted with content analysis, a more traditional qualitative approach. Results from a photovoice study utilizing a participatory action research framework was compared to an analysis of the audio-transcripts from that study utilizing content analysis methodology. Major similarities between the results are identified with some notable differences. Content analysis provides a more in-depth and abstract elucidation of the nature of the challenges and supports of the family caregiver. The comparison provides evidence to support the trustworthiness of photovoice methodology with limitations identified. The enhanced elaboration of theme and categories with content analysis may have some advantages relevant to the utilization of this knowledge by health care professionals.

  3. Critical Research Needed to Examine the Environmental Impacts of Expanded Refrigeration on the Food System.

    2016-11-15

    The unbroken global refrigerated supply chain, or cold chain, is rapidly expanding in developing countries. In addition to increasing the energy intensity of the food system, the expanded cold chain may facilitate changes in the global diet, food waste patterns, food production and distribution, and shopping habits. The sustainability impacts of many of these changes chain are unknown, given the complexity of interacting social, economic, and technical factors. The current literature surrounding the environmental impacts of refrigeration in the food system focuses on the direct impacts of energy use and coolant emissions, and lacks a critical evaluation of the accompanying systemic societal changes that potentially carry greater environmental impacts. This review examines the cold chain as a transformative technology, identifying key intrinsic, indirect, and external factors that will favorably, unfavorably, or ambiguously impact the environmental profile of the food system. The review identifies key interactions and feedbacks between the cold chain, food production and consumption decisions, infrastructure development, and the global environment which are largely unexamined and in need of empirical data. Viewing cold chain expansion from this broader perspective is essential to understanding the changing impacts of the food system in developing countries and may inform future sustainability planning.

    2018-02-13

    Coarse exposure assessment and assignment is a common issue facing epidemiological studies of shift work. Such measures ignore a number of exposure characteristics that may impact on health, increasing the likelihood of biased effect estimates and masked exposure-response relationships. To demonstrate the impacts of exposure assessment precision in shift work research, this study investigated relationships between work schedule and depression in a large survey of Canadian nurses. The Canadian 2005 National Survey of the Work and Health of Nurses provided the analytic sample (n = 11450). Relationships between work schedule and depression were assessed using logistic regression models with high, moderate, and low-precision exposure groupings. The high-precision grouping described shift timing and rotation frequency, the moderate-precision grouping described shift timing, and the low-precision grouping described the presence/absence of shift work. Final model estimates were adjusted for the potential confounding effects of demographic and work variables, and bootstrap weights were used to generate sampling variances that accounted for the survey sample design. The high-precision exposure grouping model showed the strongest relationships between work schedule and depression, with increased odds ratios [ORs] for rapidly rotating (OR = 1.51, 95% confidence interval [CI] = 0.91-2.51) and undefined rotating (OR = 1.67, 95% CI = 0.92-3.02) shift workers, and a decreased OR for depression in slow rotating (OR = 0.79, 95% CI = 0.57-1.08) shift workers. For the low- and moderate-precision exposure grouping models, weak relationships were observed for all work schedule categories (OR range 0.95 to 0.99). Findings from this study support the need to consider and collect the data required for precise and conceptually driven exposure assessment and assignment in future studies of shift work and health. Further research into the effects of shift rotation frequency on depression is

    Tubes of AISI 304 stainless steel as well as tubes of Aluminum 1100-F are used as cladding of the fuel elements of TRIGA MARK 1 nuclear research reactor. Usually, these tubes are periodically inspected by means of visual test and sipping test. The visual test allows the detection of changes occurred at the external fuel elements surface, such as those promoted by corrosion processes. However, this test method cannot be used for detection of internal discontinuities at the tube walls. Sipping test allows the detection of fuel elements in which the cladding has failed, but it is not able to determine the place where the discontinuity is located. In turn, eddy current testing, an electromagnetic nondestructive test method, allows the detection of discontinuities and monitoring their growth. In this paper, a study about the use of eddy current testing for detection and characterization of discontinuities in the fuel elements cladding is proposed. The study involves the development of probes able to operate in underwater inspections, the design and manufacture of reference standards and the development of a test methodology to perform the evaluations.

    To evaluate the characteristics and outcomes of ureteroscopy (URS) in children treated in several hospitals participating in the Clinical Research Office of the Endourological Society (CROES) Study, and to present the overall results of pediatric URS compared with adults. The CROES Study collected data on consecutive patients treated with URS for urolithiasis at each participating center over a 1-year period. The collected prospective global database includes data for 11,885 patients who received URS at 114 centers in 32 countries. Of these URS-treated patients, 192 were ≤18 years old. Of the 114 centers participating in the study, 42% had conducted pediatric URS. Among the pediatric cases, 7 were infants, 53 were small children, 59 were school-aged children, and 73 were adolescents. A considerable number (37%) of the pediatric cases had previously undergone URS treatment. No differences in the surgical outcomes of the adults and children were reported. The URS-treated children had a greater number of positive preoperative urine cultures when compared with adult cases treated. A semirigid scope was used in the vast majority of pediatric cases (85%). According to the present data, within the group of URS-treated children, the younger the child, the more readmissions occurred. URS is as efficient and safe in children as it is in adults. The data suggest that readmissions among URS-treated children are associated with age, with the likelihood of readmissions greater among younger age groups. Copyright © 2016 Elsevier Inc.

    Full Text Available This article will be structured as follows: Firstly, it will be described what is to be understood by the term ‘identity’. After that, this article will explore the significance of the topic ‘identities of population’ regarding the political, social, economic and cultural developments in the border areas of East-Central and South-East Europe. Because identities are not essentially but constructed phenomena, the next chapter will deal with the role of conceptions of the border area populations for the building of identity. The then following remarks on categories of border areas shall suggest that a great variety of border areas needs to be considered if one is occupied with the subject of this article. From these explanations the article’s relation to application will be derived, and groups of questions as well as detailed questions will be developed.

    The Distress Disclosure Index (DDI; J. H. Kahn & R. M. Hessling, 2001) is a brief self-report measure of one's tendency to disclose personally distressing information. The purpose of this article was to summarize what is known about the DDI, present new validity evidence, and make recommendations for use of the DDI. This article reviews research on the DDI from the past decade that indicates that distress disclosure is associated with well-being, professional help-seeking attitudes and intentions, and success in brief psychotherapy. On the basis of the reviewed literature, the authors report a reliability generalization study of DDI scores that strongly supports the internal consistency and test-retest reliability of DDI scores, and they review criterion-related and construct validity evidence. Next, the authors present a new multitrait-multimethod validity study of the DDI. Participants (N = 153) and peer informants (N = 153)--one per participant--completed paper-and-pencil questionnaire packets. Convergent validity of self-reported DDI scores was supported by a strong association with self-reports of emotional self-disclosure in response to a specific, unpleasant event, and self- and peer reports on the DDI were moderately correlated. DDI scores were not strongly associated with cognitive reappraisal and ambivalence over emotional expression, thus supporting discriminant validity. DDI scores were strongly associated with expressive suppression, and correlations between DDI scores and affect, depression symptoms, coping, and emotional expressivity were similar to those found with expressive suppression. The authors offer possible hypotheses explaining the overlap between distress disclosure and expressive suppression and present recommendations for future use of the DDI.

    2012-01-01

    Death certificates and medical examiner records have been useful yet imperfect data sources for work-related fatality research and surveillance among adult workers. It is unclear whether this holds for work-related fatalities among adolescent workers who suffer unique detection challenges in part because they are not often thought of as workers. This study investigated the utility of using these data sources for surveillance and research pertaining to adolescent work-related fatalities. Using the state of North Carolina as a case study, we analyzed data from the death certificates and medical examiner records of all work-related fatalities data among 11- to 17-year-olds between 1990-2008 (N = 31). We compared data sources on case identification, of completeness, and consistency information. Variables examined included those on the injury (e.g., means), occurrence (e.g., place), demographics, and employment (e.g., occupation). Medical examiner records (90%) were more likely than death certificates (71%) to identify adolescent work-related fatalities. Data completeness was generally high yet varied between sources. The most marked difference being that in medical examiner records, type of business/industry and occupation were complete in 72 and 67% of cases, respectively, while on the death certificates these fields were complete in 90 and 97% of cases, respectively. Taking the two sources together, each field was complete in upward of 94% of cases. Although completeness was high, data were not always of good quality and sometimes conflicted across sources. In many cases, the decedent's occupation was misclassified as "student" and their employer as "school" on the death certificate. Even though each source has its weaknesses, medical examiner records and death certificates, especially when used together, can be useful for conducting surveillance and research on adolescent work-related fatalities. However, extra care is needed by data recorders to ensure that

The paper contains a general description of the INR post-irradiation facility and methods and the relevant post-irradiation examination results obtained from an irradiated experimental CANDU type fuel element designed, manufactured and tested by INR in a power ramp test in the 100 kW Pressurised Water Irradiation Loop of the TRIGA 14 MW(th) Reactor. The irradiation experiment consisted in testing an assembly of six fuel elements, designed to reach a bumup of ∼ 200 MWh/kgU, with typical CANDU linear power and ramp rate. (author)

  15. Don’t Be Afraid to Ask the Question: A Simple Guide for Veterinary Nurses to Conducting Evidence-Based Research in Clinical Practice

    Directory of Open Access Journals (Sweden)

    Sue Badger

    2017-01-01

    Full Text Available The evolution of veterinary nursing over the past fifty years combined with the introduction of the RCVS Register and Code of Conduct means that RVN's are now accountable for their actions and as a result must develop the ability to critically appraise, both their own practice and the protocols of the organisation in which they work, as part of clinical governance. It is therefore important that they develop the tools which enable them to confidently question all aspects of their clinical practice, but especially patient care and welfare, where necessary.This is a podcast of Sue and Andrea's talk at the Veterinary Evidence Today conference, Edinburgh November 1, 2016.

  17. Phrasal Paraphrase Based Question Reformulation for Archived Question Retrieval.

    Directory of Open Access Journals (Sweden)

    Yu Zhang

    Full Text Available Lexical gap in cQA search, resulted by the variability of languages, has been recognized as an important and widespread phenomenon. To address the problem, this paper presents a question reformulation scheme to enhance the question retrieval model by fully exploring the intelligence of paraphrase in phrase-level. It compensates for the existing paraphrasing research in a suitable granularity, which either falls into fine-grained lexical-level or coarse-grained sentence-level. Given a question in natural language, our scheme first detects the involved key-phrases by jointly integrating the corpus-dependent knowledge and question-aware cues. Next, it automatically extracts the paraphrases for each identified key-phrase utilizing multiple online translation engines, and then selects the most relevant reformulations from a large group of question rewrites, which is formed by full permutation and combination of the generated paraphrases. Extensive evaluations on a real world data set demonstrate that our model is able to characterize the complex questions and achieves promising performance as compared to the state-of-the-art methods.

    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.

  20. Disability Discrimination and Obesity: The Big Questions?

    Science.gov (United States)

    Flint, Stuart W; Snook, Jeremé

    2015-12-01

    Obesity discrimination in employment and recruitment has become a topic of focus for research examination with increasing reports of discrimination by colleagues and managers. Whilst a limited number of legal cases have emerged, disability law is consulted in line with the expectation of anti-discriminatory practices at work. In line with disability law, whether obesity is defined as a disability or not has an impact on the outcome of a court ruling. Ambiguity when defining obesity through either the medical or social model means there are many questions that remain unanswered which might lead to inconsistency in court rulings.

  1. Diagnostic strategies using physical examination are minimally useful in defining carpal tunnel syndrome in population-based research studies.

    Descatha, A; Dale, A-M; Franzblau, A; Coomes, J; Evanoff, B

    2010-02-01

    We evaluated the utility of physical examination manoeuvres in the prediction of carpal tunnel syndrome (CTS) in a population-based research study. We studied a cohort of 1108 newly employed workers in several industries. Each worker completed a symptom questionnaire, a structured physical examination and nerve conduction study. For each hand, our CTS case definition required both median nerve conduction abnormality and symptoms classified as "classic" or "probable" on a hand diagram. We calculated the positive predictive values and likelihood ratios for physical examination manoeuvres in subjects with and without symptoms. The prevalence of CTS in our cohort was 1.2% for the right hand and 1.0% for the left hand. The likelihood ratios of a positive test for physical provocative tests ranged from 2.0 to 3.3, and those of a negative test from 0.3 to 0.9. The post-test probability of positive testing was study found that physical examination, alone or in combination with symptoms, was not predictive of CTS in a working population. We suggest using specific symptoms as a first-level screening tool, and nerve conduction study as a confirmatory test, as a case definition strategy in research settings.

    It is good practice for the public to be involved in developing research ideas into grant applications. Some positive accounts of this process have been published, but little is known about when their reactions are negative and when researchers' ideas are abandoned. To present a case study account of when an academic-led idea for funding was not supported by stroke survivors and carers who were asked to contribute to its development, together with a reflection on the implications of the case from all the stakeholders involved. A reflective case study of a research idea, developed by an academic researcher, on which stakeholders were consulted. University researchers, clinicians, public involvement managers, and stroke survivors and carers from the NIHR's Stroke Research Network. Although the idea met with the approval of health professionals, who were keen to develop it into a funding bid, the stroke survivors and carers did not think the idea worth pursuing. This lack of patient and carer support led to the idea being abandoned. Reflecting on this, those involved in the consultation believed that the savings accrued from abandoning the idea, in terms of ensuring that public money is not wasted, should be seen as an important benefit of public involvement in the research process. Little is known about the role of the public in the abandonment of research ideas. We recommend that further research is undertaken into this important contribution that patients and the public can make to health research. © 2012 John Wiley & Sons Ltd.

  5. Student questions in urban middle school science communities of practice

    Science.gov (United States)

    Groome, Meghan

    This dissertation examines student questions within three Communities of Practice (CoP), all urban middle school science environments. The study analyzed student questions from a sociocultural perspective and used ethnographic research techniques to detail how the CoP's shaped questions in the classroom. In the first study, two case study girls attempted to navigate questioning events that required them to negotiation participation. Their access to participation was blocked by participation frameworks that elevated some students as "gatekeepers" while suppressing the participation of others. The next two studies detail the introduction of written questioning opportunities, one into a public middle school classroom and the other into an informal classroom. In both studies, students responded to the interventions differently, most notable the adoption of the opportunity by female students who do not participate orally. Dissertation-wide findings indicate all students were able to ask questions, but varied in level of cognitive complexity, and the diagnostic interventions were able to identify students who were not known to be "target students", students who asked a high number of questions and were considered "interested in science". Some students' roles were as "gatekeepers" to participation of their peers. Two out of three teachers in the studies reported major shifts in their teaching practice due to the focus on questions and the methods used here have been found to be effective in producing educational research as well as supporting high-need classrooms in prior research. In conclusion, these studies indicate that social factors, including participation frameworks, gender dynamics, and the availability of alternative participation methods, play an important role in how students ask science-related questions. It is recommended that researchers continue to examine social factors that reduce student questions and modify their teaching strategies to facilitate

  9. Examination of China’s performance and thematic evolution in quantum cryptography research using quantitative and computational techniques

    Science.gov (United States)

    2018-01-01

    This study performed two phases of analysis to shed light on the performance and thematic evolution of China’s quantum cryptography (QC) research. First, large-scale research publication metadata derived from QC research published from 2001–2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China’s QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China’s performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China’s performance indicators (i.e., Publication Frequency, citation score, H-index) are growing. China’s H-index (a normalized indicator) has surpassed all other countries’ over the last several years. The second phase of analysis shows how China’s main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures); some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state), while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation). Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China’s QC research themes, which can provide clarity into how QC technologies might take shape.

    The experimental fast reactor Joyo at Oarai Research and Development Center (ORDC) of Japan Atomic Energy Agency (JAEA) is Japan's sodium-cooled fast reactor (FR). In 2003, this reactor's upgrade to the 140MWt MK-III core was completed to increase the irradiation testing capability. The MK-III core provides the fast neutron flux of 4.0x10 15 n/cm 2 s as an irradiation test bed for improving the fuels and material of FR in Japan. Three post-irradiation examination (PIE) facilities named FMF, MMF and AGF related to Joyo are in ORDC. Irradiated subassemblies and core components are carried into the FMF (Fuel Monitoring Facility) and conducted nondestructive examinations. Each subassembly is disassembled to conduct some destructive examinations and to prepare the fuel and material samples for further detailed examinations. Fuel samples are sent to the AGF (Alpha-Gamma Facility), and material samples are sent to the MMF (Materials Monitoring Facility). These overall and elaborate data provided by PIE contribute to investigate the irradiation effect and behavior of fuels and materials. This facility complex is indispensable to promote the R and D of FR in Japan. And, the function and technology of irradiation test and PIE enable to contribute to the R and D of innovative fission or fusion reactor material which will be required to use under the high neutron exposure.

In appreciation of this challenge, the Canadian Obesity Network (CON has run an interdisciplinary summer training camp for graduate students, new career researchers, and clinicians for the past 8 years. This paper evaluates the effects of attending this training camp on trainees' early careers. We use social network analysis to examine the professional connections developed among trainee Canadian obesity researchers who attended this camp over its first 5 years of operation (2006–2010. We examine four relationships (knowing, contacting, and meeting each other, and working together among previous trainees. We assess the presence and diversity of these relationships among trainees across different years and disciplines and find that interdisciplinary contact and working relationships established at the training camp have been maintained over time. In addition, we evaluate the qualitative data on trainees' career trajectories and their assessments of the impact that the camp had on their careers. Many trainees report that camp attendance had a positive impact on their career development, particularly in terms of establishing contacts and professional relationships. Both the quantitative and the qualitative results demonstrate the importance of interdisciplinary training and relationships for career development in the health

  17. Management of spent fuel from research and prototype power reactors and residues from post-irradiation examination of fuel

    International Nuclear Information System (INIS)

    1989-09-01

    The safe and economic management of spent fuel is important for all countries which have nuclear research or power reactors. It involves all aspects of the handling, transportation, storage, conditioning and reprocessing or final disposal of the spent fuel. In the case of spent fuel management from power reactors the shortage of available reprocessing capacity and the rising economic interest in the direct disposal of spent fuel have led to an increasing interest in the long term storage and management of spent fuel. The IAEA has played a major role in coordinating the national activities of the Member States in this area. It was against this background that the Technical Committee Meeting on ''Safe Management of Spent Fuel From Research Reactors, Prototype Power Reactors and Fuel From Commercial Power Reactors That Has Been Subjected to PIE (Post Irradiated Examination)'' (28th November - 1st December 1988) was organised. The aims of the current meeting have been to: 1. Review the state-of-the-art in the field of management of spent fuel from research and prototype power reactors, as well as the residues from post irradiation examination of commercial power reactor fuel. The emphasis was to be on the safe handling, conditioning, transportation, storage and/or disposal of the spent fuel during operation and final decommissioning of the reactors. Information was sought on design details, including shielding, criticality and radionuclide release prevention, heat removal, automation and remote control, planning and staff training; licensing and operational practices during each of the phases of spent fuel management. 2. Identify areas where additional research and development are needed. 3. Recommend areas for future international cooperation in this field. Refs, figs and tabs

  1. Can Archival Tissue Reveal Answers to Modern Research Questions?: Computer-Aided Histological Assessment of Neuroblastoma Tumours Collected over 60 Years

    Directory of Open Access Journals (Sweden)

    Albert Chetcuti

    2014-02-01

    Full Text Available Despite neuroblastoma being the most common extracranial solid cancer in childhood, it is still a rare disease. Consequently, the unavailability of tissue for research limits the statistical power of studies. Pathology archives are possible sources of rare tissue, which, if proven to remain consistent over time, could prove useful to research of rare disease types. We applied immunohistochemistry to investigate whether long term storage caused any changes to antigens used diagnostically for neuroblastoma. We constructed and quantitatively assessed a tissue microarray containing neuroblastoma archival material dating between 1950 and 2007. A total of 119 neuroblastoma tissue cores were included spanning 6 decades. Fourteen antibodies were screened across the tissue microarray (TMA. These included seven positive neuroblastoma diagnosis markers (NB84, Chromogranin A, NSE, Ki-67, INI1, Neurofilament Protein, Synaptophysin, two anticipated to be negative (S100A, CD99, and five research antibodies (IL-7, IL-7R, JAK1, JAK3, STAT5. The staining of these antibodies was evaluated using Aperio ImageScope software along with novel pattern recognition and quantification algorithms. This analysis demonstrated that marker signal intensity did not decrease over time and that storage for 60 years had little effect on antigenicity. The construction and assessment of this neuroblastoma TMA has demonstrated the feasibility of using archival samples for research.

  4. Repetitive Questioning Exasperates Caregivers

    Directory of Open Access Journals (Sweden)

    R. C. Hamdy MD

    2018-01-01

    Full Text Available Repetitive questioning is due to an impaired episodic memory and is a frequent, often presenting, problem in patients with Alzheimer’s disease (amnestic type. It is due to the patients’ difficulties learning new information, retaining it, and recalling it, and is often aggravated by a poor attention span and easy distractibility. A number of factors may trigger and maintain repetitive questioning. Caregivers should try to identify and address these triggers. In the case discussion presented, it is due to the patient’s concerns about her and her family’s safety triggered by watching a particularly violent movie aired on TV. What went wrong in the patient/caregiver interaction and how it could have been avoided or averted are explored. Also reviewed are the impact of repetitive questioning, the challenges it raises for caregivers, and some effective intervention strategies that may be useful to diffuse the angst that caregivers experience with repetitive questioning.

  6. 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.

  7. A Technique Socratic Questioning-Guided Discovery

    M. Hakan Türkçapar

    2012-03-01

    Full Text Available “Socratic Method” is a way of teaching philosophical thinking and knowledge by asking questions which was used by antique period greek philosopher Socrates. Socrates was teaching knowledge to his followers by asking questions and the conversation between them was named “Socratic Dialogues”. In this meaning, no novel knowledge is taught to the individual but only what is formerly known is reminded and rediscovered. The form of socratic questioning which is used during the process of cognitive behavioral therapy is known as Guided Discovery. In this method it is aimed to make the client notice the piece of knowledge which he could notice but is not aware with a series of questions. Socratic method or guided discovery consists of several steps which are: Identifying the problem by listening to the client and making reflections, finding alternatives by examining and evaluating, reidentification by using the newly found information and questioning the old distorted belief and reaching to a conclusion and applying it. Question types used during these procedures are, questions for gaining information, questions revealing the meanings, questions revealing the beliefs, questions about behaviours during the similar past experiences, analyse questions and analytic synthesis questions. In order to make the patient feel understood it is important to be empathetic and summarising the problem during the interview. In this text, steps of Socratic Questioning-Guided Discovery will be reviewed with sample dialogues after each step

  8. When the Research Design Matters in EFL Context: A Case of Different Responses to Open-response and Closed-response Questions on Motivational Orientation

    Directory of Open Access Journals (Sweden)

    Ma‘ssoumeh Bemani Naeini

    2012-11-01

    Full Text Available This study aimed at investigating and exploring the degree of motivational orientation (i.e. instrumental and integrative motivation among sixty Iranian TEFL students. A survey research design was used to collect both quantitative and qualitative data, using a Likert-scale questionnaire containing six open-response items. Inferential analysis of quantitative data identified the subjects of the study with integrative orientation. However, descriptive analysis of open responses in terms of coded recurrent themes indicated contradictory results. In sum, the findings suggest a gap between Iranian TEFL students’ “desirable motivation” and “desired motivation”. The researcher attributes the contradictory results not only to the social context, but also to the type of questionnaire and the psychological status of respondents. Also, the findings provide support for other components of motivation other than just instrumentality and integrativeness, mainly “personal” aspects as proposed by Benson’s model of motivation.

  11. The Question Concerning Thinking

    2008-01-01

    Martin Heidegger's thought-provoking essay "The Question Concerning Technology" (1977a) placed technology at the heart of philosophy. Heidegger tried to show that the essence of technology provokes humans to think about the world in a very dangerous way. Yet if we follow Heidegger's analysis...... of technology, what role does that ascribe to philosophy? To be able to understand the programmatic scope of Heidegger's question ‘concerning' technology, we need to see it as inseparable from his famous thesis about the end of philosophy (1977c) and what he considers to be the ideal kind of thinking. However......, by doing so, we will in the end realize two important things. First, that Heidegger's declaration of the end of philosophy in fact also means the end of anything we can meaningfully call thinking. Second, that Heidegger's own thinking is completely different from his own ideal of thinking. Our question...

  12. Different perspectives of cultural mediation: implications for the research design on studies examining its effect on students' cognition

    In this forum, I extend Tao, Oliver, and Venville's paper Chinese and Australian children's understanding of the earth: a cross cultural study of conceptual development to discuss the different views on culture and cultural mediation. I tease out nuances in the viewpoints to suggest three ways to theoretically frame studies examining cultural mediation of students' cognition. Specifically, cultural mediation may be attributed to innate psychological attributes, an accretion of cultural elements, or the social interaction process. Each of these ideas represents a theoretical lens and has implications for the research design of studies relating cultural mediation to cognition. In the final section of this forum paper, I show how a study conducted from the symbolic interactionist viewpoint underscoring cultural mediation as a social interaction process might unfold.

    Woodsmoke pollution is an environmental justice issue for youth living in certain Pacific Northwest cities. Participatory methods such as Citizen Science and Photovoice are effective ways to involve youth in environmental justice research. Little is understood about how youth may be empowered to address woodsmoke issues in their communities. We examined youth empowerment in a citizen science study on woodsmoke, using Photovoice methodology. Ten diverse youth collected and analyzed indoor air samples and photos, then presented their findings to the community and policy makers. Entrance and exit surveys revealed an increased sense of empowerment to take action on woodsmoke pollution. Youth also expressed increased optimism and a resolve to become scientists to combat environmental injustices.

    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.

  15. Examining how youth of color engage youth participatory action research to interrogate racism in their science experiences

    Science.gov (United States)

    Sato, Takumi C.

    While many researchers have worked to address the unequal educational outcomes between White and non-White students, there are few signs of progress for people of color seeking entry into a STEM career trajectory. Starting from high school, the number of students who persist to complete a STEM bachelor's degree and obtaining a job in science or engineering continues to indicate that people of color are underrepresented. I suggest that research must consider the role of race and racism in the education of youth of color. Especially in science education, there is very little work addressing how racism may present barriers that impede progress for students along the STEM trajectory. This study is informed by critical race theory (CRT) that posits racism is endemic in society. White privilege enables the dominant group to maintain inequitable advantages that marginalizes populations of color. CRT also puts forth that counter narratives of the marginalized groups is essential to challenge the institutionalized forms of oppression. Using CRT and youth participatory action research (YPAR), this investigation re-imagines youth as capable of transforming their own social and political condition through research and action. This project asked youth of color to interrogate their own experiences as science learners, engage in research on structural inequities of STEM trajectories, plan strategic moves to challenge power structures, and take action for social justice. The youth started by exploring the concept of race and instances where racism was found in public spaces and in their personal experiences. They examined their experiences in science as a student more generally and then for racism. Then, the focus turned to conducting research with peers, observing science classrooms in another school, and using online information to compare schools. The youth planned strategic action against the racism they found in the analysis of the data that included conference presentations

    Individual and environment are a hierarchical structure consist of units grouped at different levels. Hierarchical data structures are analyzed based on several levels, with the lowest level nested in the highest level. This modeling is commonly call multilevel modeling. Multilevel modeling is widely used in education research, for example, the average score of National Examination (UN). While in Indonesia UN for high school student is divided into natural science and social science. The purpose of this research is to develop multilevel and panel data modeling using linear mixed model on educational data. The first step is data exploration and identification relationships between independent and dependent variable by checking correlation coefficient and variance inflation factor (VIF). Furthermore, we use a simple model approach with highest level of the hierarchy (level-2) is regency/city while school is the lowest of hierarchy (level-1). The best model was determined by comparing goodness-of-fit and checking assumption from residual plots and predictions for each model. Our finding that for natural science and social science, the regression with random effects of regency/city and fixed effects of the time i.e multilevel model has better performance than the linear mixed model in explaining the variability of the dependent variable, which is the average scores of UN.

    Vaccine disparities research often focuses on differences between the five main racial and ethnic classifications, ignoring heterogeneity of subpopulations. Considering this knowledge gap, we examined human papillomavirus (HPV) vaccine initiation in Asian Indians and Asian subpopulations. National Health Interview Survey data (2008-2013), collected by the National Center for Health Statistics, were analyzed. Multiple logistic regression analysis was conducted on adults aged 18-26 years (n = 20,040). Asian Indians had high income, education, and health insurance coverage, all positive predictors of preventative health engagement and vaccine uptake. However, we find that Asian Indians had comparatively lower rates of HPV vaccine initiation (odds ratio = 0.41; 95% confidence interval = 0.207-0.832), and foreign-born Asian Indians had the lowest rate HPV vaccination of all subpopulations (2.3%). Findings substantiate the need for research on disaggregated data rather than evaluating vaccination behaviors solely across standard racial and ethnic categories. We identified two populations that were initiating HPV vaccine at abysmal levels: foreign-born persons and Asian Indians. Development of culturally appropriate messaging has the potential to improve these initiation rates and improve population health. Copyright © 2017 The Royal Society for Public Health.

To investigate, using mixed methods, non-invitation of eligible families and ensuing selection bias in an interview study about parents' experiences of advance care planning (ACP). We examined differences between eligible families invited and not invited to participate by clinicians using (1) field notes of discussions with clinicians during the invitation phase and (2) anonymised information from the service's clinical database. Families were eligible for the ACP study if their child was receiving care from a UK-based tertiary palliative care service (Group A; N = 519) or had died 6-10 months previously having received care from the service (Group B; N = 73). Rates of non-invitation to the ACP study were high. A total of 28 (5.4%) Group A families and 21 (28.8%) Group B families (p research findings.

    The construction project of the Kijang research reactor (KJRR), which is the second research reactor in Korea, has been launched. The KJRR was designed to use, for the first time, U–Mo fuel. Plate-type U–7 wt.% Mo/Al–5 wt.% Si, referred to as U–7Mo/Al–5Si, dispersion fuel with a uranium loading of 8.0 gU/cm{sup 3}, was selected to achieve higher fuel efficiency and performance than are possible when using U{sub 3}Si{sub 2}/Al dispersion fuel. To qualify the U–Mo fuel in terms of plate geometry, the first miniplates [HANARO Miniplate (HAMP-1)], containing U–7Mo/Al–5Si dispersion fuel (8 gU/cm{sup 3}), were fabricated at the Korea Atomic Energy Research Institute and recently irradiated at HANARO. The PIE (Post-irradiation Examination) results of the HAMP-1 irradiation test were analyzed in depth in order to verify the safe in-pile performance of the U–7Mo/Al–5Si dispersion fuel under the KJRR irradiation conditions. Nondestructive analyses included visual inspection, gamma spectrometric mapping, and two-dimensional measurements of the plate thickness and oxide thickness. Destructive PIE work was also carried out, focusing on characterization of the microstructural behavior using optical microscopy and scanning electron microscopy. Electron probe microanalysis was also used to measure the elemental concentrations in the interaction layer formed between the U–Mo kernels and the matrix. A blistering threshold test and a bending test were performed on the irradiated HAMP-1 miniplates that were saved from the destructive tests. Swelling evaluation of the U–Mo fuel was also conducted using two methods: plate thickness measurement and meat thickness measurement.

    Operational conjectures about space exploration missions of the future indicate that space crews will need to be more autonomous from mission control and operate independently. This is in part due to the expectation that communication quality between the ground and exploration crews will be more limited and delayed. Because of potential adverse effects on communication quality, both researchers and operational training and engineering experts have suggested that communication delays and the impact these delays have on the quality of communications to the crew will create performance decrements if crews are not given adequate training and tools to support more autonomous operations. This presentation will provide an overview of a research study led by the Behavioral Health and Performance Element (BHP) of the NASA Human Research Program that examines the impact of implementing a communication delay on ISS on individual and team factors and outcomes, including performance and related perceptions of autonomy. The methodological design, data collection efforts, and initial results of this study to date will be discussed . The results will focus on completed missions, DRATS and NEEMO15. Lessons learned from implementing this study within analog environments will also be discussed. One lesson learned is that the complexities of garnishing a successful data collection campaign from these high fidelity analogs requires perseverance and a strong relationship with operational experts. Results of this study will provide a preliminary understanding of the impact of communication delays on individual and team performance as well as an insight into how teams perform and interact in a space-like environment . This will help prepare for implementation of communication delay tests on the ISS, targeted for Increment 35/36.

    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.

    Full Text Available The article presents the analysis of 342 questions on the theme "Water", proposed by 114 students from three elementary schools in the South region of Brazil, in order to identify interdisciplinary articulations associated with complex thinking present in these questions. The research sought to answer the following question: What revelations can emerge from the analysis of student's questions about a specific topic of study, such as "Water", in relation to interdisciplinarity and complex thinking? From the discursive textual analysis of the questions, two categories emerged: disciplinary questions; and interdisciplinary questions. The examination of the content of the categories enabled the writing of metatexts that reveal that in the text of most of the students' questions, is present a complex mode of thinking and interdisciplinary relationships, since 77.8% of the questions belong to second category. This can be an indication to teachers of how to initiate pedagogical actions, whose focus is interdisciplinarity.

    The Mini-Mental State Examination (MMSE) is the most widely used cognitive screening test around the world. In Brazil, different MMSE versions and many cut-off points have been used. A systematic review of papers indexed in Scielo was conducted in order to analyze use of the MMSE in Brazilian empirical studies with elderly people. To search for these texts, the complete name of the instrument and its abbreviation were used. A growth trend in the scientific production during the 1998 to 2013 period was observed. Eleven versions of the MMSE were identified and the Bertolucci et al. version was the most cited. Over half of the studies used schooling as the criteria to establish cut-off points. The studies were predominantly conducted using samples recruited from large cities in the Southeastern region and in the community. Despite the growing trend of research with the elderly using the MMSE, the psychometric properties of this scale of measurement have been the subject of little investigation. Despite the widespread use of the MMSE in Brazil, there is a lack of standardization and evidence of validity for this this scale of measurement.

    2009-03-01

    We examined the question-is the intention of completing a simulated motor action the same as the intention used in processing overt actions? Participants used motor imagery to estimate distance reachability in two conditions: Imagery-Only (IO) and Imagery-Execution (IE). With IO (red target) only a verbal estimate using imagery was given. With IE (green target) participants knew that they would actually reach after giving a verbal estimate and be judged on accuracy. After measuring actual maximum reach, used for the comparison, imagery targets were randomly presented across peripersonal- (within reach) and extrapersonal (beyond reach) space. Results indicated no difference in overall accuracy by condition, however, there was a significant distinction by space; participants were more accurate in peripersonal space. Although more research is needed, these findings support an increasing body of evidence suggesting that the neurocognitive processes (in this case, intention) driving motor imagery and overt actions are similar.

    We investigate the question of neutrino mass in theories in which neutrinos are four-component Dirac particles. Our analysis is done in the framework of left-right--symmetric theories. The requirement of calculability and natural smallness of neutrino mass leads to the following constraints: (i) left and right charged weak currents must be ''orthogonal'' to each other, and (ii) there should be no W/sub L/-W/sub R/ mixing at the three level. Finally, we exhibit a model in which, due to the existence of an unbroken symmetry of the total Lagrangian, the electron and muon neutrinos remain massless to all orders in perturbation theory

    To monitor the conduct of medical research projects that have already been approved by the local medical research ethics committee. Follow up study of ethically approved studies (randomly selected from all the studies approved in the previous year) by examination of patients' case notes, consent forms, and research records and by interview of the researchers at their workplace. Tayside, Scotland (mixed rural and urban population). 30 research projects approved by Tayside local medical research ethics committee. Adherence to the agreed protocol, particularly for recruitment (obtaining and recording informed consent) and for specific requirements of the ethics committee, including notification of changes to the protocol and of adverse events. In one project only oral consent had been obtained, and in a quarter of the studies one or more consent forms were incorrectly completed. Inadequate filing of case notes in five studies and of consent forms in six made them unavailable for scrutiny. Adverse events were reported, but there was a general failure to report the abandoning or non-starting of projects in two studies the investigators failed to notify a change in the responsible researcher. Monitoring of medical research by local medical research ethics committees promotes and preserves ethical standards, protects subjects and researchers, discourages fraud, and has the support of investigators. We recommend that 10% of projects should undergo on-site review, with all others monitored by questionnaire. This would require about six person hours of time and a salary bill of 120 pounds per study monitored.

    Full Text Available I examine how teachers employ a questioning strategy in supporting Grade 9 learners doing science investigations in South African schools. A particular focus of this study was how teachers use questioning in contributing towards the autonomy of these learners. The research adopted a qualitative approach which involved the collection of data by means of classroom observations and interviews with five teachers at schools resourced for practical work. The analysis of transcript data revealed that teachers support learners by asking probing questions at all stages of the investigation. The teachers used a questioning strategy in enabling the learners to understand more clearly the question or hypothesis they intended investigating, to review and reconsider their planning, to rethink some of their actions when collecting data, to make sense of their data, and to revisit and amend their plan after generating incorrect findings. The significance of this study, in making explicit teacher questioning at the stages of the investigation, is that it provides a guideline for teachers on how to support learners attain greater autonomy in doing science investigations.

    Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers' (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenomena at hand, the present study closely examines both cognitive and affective domains of: (a) teachers' views (via interviews) concerning: (1) importance and roles of teacher and student questions, (2) teacher responses, and (3) planning and teacher training; and (b) teachers' actual practices (via classroom observations) concerning: (1) number and (2) level of teacher and student questions, as well as (3) teachers' responses to questions. The data were collected from 3 elementary, 3 middle, and 3 high school science teachers and their respective classroom students. The findings lay out a wide view of classroom questioning and teachers' responses, and relate what actually occurs in classes to teachers' stated views. Some of the study's main conclusions are that a gap exists between how science researchers and teachers view the role of teacher questions: the former highlight the cognitive domain, while the latter emphasize the affective domain.

  7. 'With woman' philosophy: examining the evidence, answering the questions.

    Carolan, Mary; Hodnett, Ellen

    2007-06-01

    'With woman', 'woman centred' and 'in partnership with women' are new terms associated with midwifery care in Australia, and the underlying philosophy has emerged both as an antidote to the medicalisation of pregnancy and in a bid to reacquaint women with their natural capacity to give birth successfully and without intervention. A reorientation of midwifery services in the 1990s, a shift towards midwifery-led care (MLC) and the subsequent introduction of direct entry midwifery programs all contributed to this new direction. Central concepts are a focus on the childbearing woman and a valuing of women's experiences. While this philosophical re-alignment has been applauded by many midwives in terms of maternal empowerment and improved autonomy for midwives, there are nonetheless some concerns that, with its emphasis on normality, midwifery-led care is in danger of becoming an exclusionary model. Particular concerns include meeting the needs of a growing cohort of women, those with 'high risk' pregnancies, and the educational adequacy of direct entry midwifery programs. To date, there has been no thorough evaluation of this emerging midwifery philosophy in Australia. In order to open the debate, this paper aims to initiate a discussion of 'with woman' midwifery care as it applies to Australian practice.

  8. Quantum theory from questions

    2016-07-01

    In contrast to relativity, quantum theory has evaded a commonly accepted apprehension, in part because of the lack of physical statements that fully characterize it. In an attempt to remedy the situation, we summarize a novel reconstruction of the explicit formalism of quantum theory (for arbitrarily many qubits) from elementary rules on an observer's information acquisition. Our approach is purely operational: we consider an observer O interrogating a system S with binary questions and define S's state as O's ''catalogue of knowledge'' about S; no ontic assumptions are necessary. From the rules, one can derive, among other things, the state spaces, the unitary group, the von Neumann evolution and show that the binary questions correspond to Pauli operators. The reconstruction also offers new structural insights in the form of novel informational charges and informational complementarity relations which define the state spaces and the unitary group. This reconstruction permits a new perspective on quantum theory.

  9. 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.

  17. The Coding Question.

    Gallistel, C R

    2017-07-01

    Recent electrophysiological results imply that the duration of the stimulus onset asynchrony in eyeblink conditioning is encoded by a mechanism intrinsic to the cerebellar Purkinje cell. This raises the general question - how is quantitative information (durations, distances, rates, probabilities, amounts, etc.) transmitted by spike trains and encoded into engrams? The usual assumption is that information is transmitted by firing rates. However, rate codes are energetically inefficient and computationally awkward. A combinatorial code is more plausible. If the engram consists of altered synaptic conductances (the usual assumption), then we must ask how numbers may be written to synapses. It is much easier to formulate a coding hypothesis if the engram is realized by a cell-intrinsic molecular mechanism. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.)

  20. Interaction between examination type, anxiety state, and academic achievement in college science; an action-oriented research

    Zoller, Uri; Ben-Chaim, David

    The trait anxiety profile of future science teachers, as well as their preferences concerning types of examinations in science and mathematics, have been surveyed prior to the administration - within the various science courses - of several traditional and nontraditional types of examinations and the assessment of students' state anxieties as well as their respective performance, i.e., their academic achievements. Our major findings are that(a)Our students prefer by far examinations in which the emphasis is on understanding and analyzing rather than on knowing and remembering, that the use of any relevant material during the examinations be permitted, and that the time duration be practically unlimited (e.g., take-home-type examinations).(b)Students' state anxiety correlates with the type of the examination, with a tendency towards somewhat higher anxiety for females. The preferred types of examinations reduce test anxiety significantly, and result in higher grades accordingly.(c)The reduction of anxiety and the improvement in achievements as a function of the examination type are far more significant for low achievers compared with medium and high achievers.(d)Although teachers are aware of the student preferences, they persist in giving their students their own pet-type examinations.These results are discussed in terms of the implications for upgrading both science education and college student testing and assessment mechanisms.

    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.

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.

    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 .

    2009-01-01

    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.)

    Science.gov (United States)

    Moore, Brooke A; Klingner, Janette K

    2014-01-01

    This article synthesizes reading intervention research studies intended for use with struggling or at-risk students to determine which studies adequately address population validity, particularly in regard to the diverse reading needs of English language learners. An extensive search of the professional literature between 2001 and 2010 yielded a total of 67 reading intervention studies targeting at-risk elementary students. Findings revealed that many current research studies fail to adequately describe the sample, including the accessible and target populations, and to disaggregate their findings based on demographic characteristics. When population validity issues are not addressed, researchers cannot generalize findings to other populations of students, and it becomes unclear what intervention strategies work, especially with English language learner student populations. However, 25 studies did specifically recognize and address the needs of English language learners, indicating more researchers are taking into consideration the diverse needs of other struggling student populations. © Hammill Institute on Disabilities 2012.

    2014-01-01

    With the blooming of online social media applications, Community Question Answering (CQA) services have become one of the most important online resources for information and knowledge seekers. A large number of high quality question and answer pairs have been accumulated, which allow users to not only share their knowledge with others, but also interact with each other. Accordingly, volumes of efforts have been taken to explore the questions and answers retrieval in CQA services so as to help users to finding the similar questions or the right answers. However, to our knowledge, less attention has been paid so far to question popularity in CQA. Question popularity can reflect the attention and interest of users. Hence, predicting question popularity can better capture the users' interest so as to improve the users' experience. Meanwhile, it can also promote the development of the community. In this paper, we investigate the problem of predicting question popularity in CQA. We first explore the factors that have impact on question popularity by employing statistical analysis. We then propose a supervised machine learning approach to model these factors for question popularity prediction. The experimental results show that our proposed approach can effectively distinguish the popular questions from unpopular ones in the Yahoo! Answers question and answer repository.

  3. Proposal for a Similar Question Search System on a Q&A Site

    Directory of Open Access Journals (Sweden)

    Katsutoshi Kanamori

    2014-06-01

    Full Text Available There is a service to help Internet users obtain answers to specific questions when they visit a Q&A site. A Q&A site is very useful for the Internet user, but posted questions are often not answered immediately. This delay in answering occurs because in most cases another site user is answering the question manually. In this study, we propose a system that can present a question that is similar to a question posted by a user. An advantage of this system is that a user can refer to an answer to a similar question. This research measures the similarity of a candidate question based on word and dependency parsing. In an experiment, we examined the effectiveness of the proposed system for questions actually posted on the Q&A site. The result indicates that the system can show the questioner the answer to a similar question. However, the system still has a number of aspects that should be improved.

We trust that our colleagues and collaborators are acting properly and ethically - and not being devious, secretive or sloppy. But perhaps even more important is the public's trust in science. After all, much research is funded by taxpayers, who, quite rightly, want to know that the work will not harm them and, preferably, do them some good.

In their concepts, the main cerebellar function is to control motor behavior, Purkinje cells are the only cortical neuron receiving and integrating inputs from climbing fiber and mossy-parallel fiber pathways, and plastic modification at the parallel fiber synapses onto Purkinje cells constitutes the substrate of motor learning. Yet, because of recent technical advances and new angles of investigation, all pillars of the cerebellar doctrine now face regular re-examination. In this review, after summarizing the classic concepts and recent disputes, we attempt to synthesize an integrated view and propose a revisited version of the cerebellar doctrine. © 2014 Elsevier B.V.

    To illuminate translation practice in cross-language interview in health care research and its impact on the construction of the data. Globalisation and changing patterns of migration have created changes to the world's demography; this has presented challenges for overarching social domains, specifically, in the health sector. Providing ethno-cultural health services is a timely and central facet in an ever-increasingly diverse world. Nursing and other health sectors employ cross-language research to provide knowledge and understanding of the needs of minority groups, which underpins cultural-sensitive care services. However, when cultural and linguistic differences exist, they pose unique complexities for cross-cultural health care research; particularly in qualitative research where narrative data are central for communication as most participants prefer to tell their story in their native language. Consequently, translation is often unavoidable in order to make a respondent's narrative vivid and comprehensible, yet, there is no consensus about how researchers should address this vital issue. An integrative literature review. PubMed and CINAHL databases were searched for relevant studies published before January 2014, and hand searched reference lists of studies were selected. This review of cross-language health care studies highlighted three major themes, which identify factors often reported to affect the translation and production of data in cross-language research: (1) translation style; (2) translators; and (3) trustworthiness of the data. A plan detailing the translation process and analysis of health care data must be determined from the study outset to ensure credibility is maintained. A transparent and systematic approach in reporting the translation process not only enhances the integrity of the findings but also provides overall rigour and auditability. It is important that minority groups have a voice in health care research which, if accurately

    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.

    A study was made of various examinations which could be remotely performed on a production basis with spent fuel at the Barnwell Nuclear Fuel Plant (BNFP). These techniques could form an integral portion of fuel disassembly and canning operations. Their benefits accrue to either improved fuel storage, reprocessing, or both. In conjunctoin with these studies, evaluations have been made of the operational impact of receiving failed or canned fuel at the BNFP

    To study and master the doses to examinees receiving from the wide spread X-CT examinations, is a key issue for strengthening the medical radiation protection. In the studies of the medical exposure levels during the Eleventh Five-Year Plan period in Shanghai, based on the brands of X-CT scanners and their distributions in different levels of hospitals, a total of 45 sets (about 30% of all) of scanners were selected for the field study. Among the 8 commonly performed examinations, the scan parameters and their relevant dosimetry information for 500 adults were collected, and their typical effective doses were estimated with the dose conversion factors. The results showed that the averages of weighted CT dose index (CTDI w ) were 55.4, 12.5 and 18.4 mGy, and the dose length products (DLP) were averaged to be 603, 294 and 415 mGy·cm, for the skull, chest and abdomen X-CT scans, respectively. The typical effective doses were estimated to be 1.4, 5.3, and 7.5 mSv for adults in the head, chest and abdomen X-CT scans, respectively. The values of CTDI w for skull scans were generally higher than those for the ear canal, eye, or sinus examinations. It is clear that the optimization between the image quality and the radiation dose should be further strengthened. Particular attentions should be paid in selecting the scanning parameters for various types of X-CT scans, and the diagnostic reference levels for X-CT examinations should be continuously improved.

    Science education standards place a high priority on promoting the skills and dispositions associated with inquiry at all levels of learning. Yet, the questions teachers employ to foster sustained reasoning are most likely borrowed from a textbook, lab manual, or worksheet. Such generic questions generated for a mass audience, lack authenticity and contextual cues that allow learners to immediately appreciate a question’s relevance. Teacher queries intended to motivate, guide, and foster learning through inquiry are known as focus questions. This theoretical article draws upon science education research to present a typology and conceptual framework intended to support science teacher educators as they identify, develop, and evaluate focus questions with their students.

  19. Fundamental elements in examining a child’s right to education: A study of home education research and regulation in Australia

    Full Text Available Home education provides valuable educational and developmental opportunities for children. An examination of Australia’s research indicates many best educational practices, including more informed mediation, contextualised learning, and opportunities to exercise autonomy. Key features include learning embedded in communities and program modification in response to students’ needs. Current state and territory legal requirements are examined within the context of this research and Australia’s obligations to international human rights treaties. All jurisdictions accept home education as one way to meet compulsory education requirements. The extent to which respective laws then reflect understanding of home education research and practice varies. Most jurisdictions allow for a varietyof educational approaches. Some oversight regulation could however be modified to reflect a better understanding of home education. Consultation with home educators and reference to research would assist the development of more uniform legislation and policy across Australia, and enable better regulatory practice.

    Balancing the demands of research and ethics is always challenging, and even more so when recruiting vulnerable groups. Within the context of current legislation and international human rights declarations, it is strongly advocated that research can and must be undertaken with all recipients of health-care services. Research in the field of intellectual disability presents particular challenges in regards to consenting processes. This paper is a reflective overview and analysis of the complex processes undertaken, and events that occurred in gaining informed consent from people with intellectual disability to participate in a study exploring their experiences of being an inpatient in mental health hospitals within Aotearoa/New Zealand. A framework based on capacity, information, and voluntariness is presented, with excerpts from the field provided to explore consenting processes. The practical implications of the processes utilized are then discussed in order to stimulate debate regarding clearer and enhanced methods of gaining informed consent from people with intellectual disability. © 2014 Australian College of Mental Health Nurses Inc.
