    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.

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. Keywords: gas laws, hypoxia-inducible factor, Krogh tissue cylinder, oxygen diffusion, partial pressure, tissue oxygen levels

    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.

    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 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.

    Korstjens, Irene; Moser, Albine

    2017-12-01

    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.

    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.

    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

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

    Full Text Available Objective ‐ To examine the similarities and differences between research questions asked by librarians in 2001 to those posed in 2006, and to explore to what extent the published research supports the questions being asked.Methods ‐ Questions collected in 2001 by members of the Evidence‐Based Librarianship Implementation Committee (EBLIC of the MLA Research Section were compared with questions collected in 2006 at a cross‐sectoral seminar introducing evidence based library and information practice to Australian librarians. Questions from each list were categorized using the domains of librarianship proposed by Crumley and Koufogiannakis in 2001, and examined with reference to a content analysis of the library and information studies (LIS research published in 2001 by Koufogiannakis, Slater, and Crumley in 2004.Results ‐ In 2001 and 2006 the most commonly asked questions were in the domain of management (29%, 33%, followed by education (24%, 18.5%. In 2001 questions in the marketing/promotion category ranked lowest (1%, however representation was much greater in 2006 (18.5% ranking an equal second with education. Questions in the lowest ranked domain in 2006 (collections, 6% had been more common in 2001 where collections ranked third, representing 19% of the questions. Koufogiannakis, Slater, and Crumley’s content analysis of LIS research published in 2001 revealed that the most popular domain for research was information access and retrieval (38% followed by collections (24%. Only 1% of published LIS research (seven articles was in the domain of marketing/promotion. In contrast, 36 articles originally assigned to one of the six established domains could more appropriately have been included in a proposed new domain of professional issues.Conclusion ‐ The disparity between questions being asked by practitioners and the evidence being generated by researchers suggests that the research‐practice gap is still an issue.

    María Eugenia Plata Santos

    2011-01-01

    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.

    Full Text Available Objective – To assess the effectiveness of a collaborative chat reference service in answering different types of question. 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

  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.

    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.

    Full Text Available Abstract In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1 the nature of a mental disorder; 2 the definition of mental disorder; 3 the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4 the role of pragmatic considerations in the construction of DSM-5; 5 the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6 the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

    In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system.

    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.

  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.

  16. Predicting self-reported research misconduct and questionable research practices in university students using an augmented Theory of Planned Behavior

    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

    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.

  18. The prime questions in authentic patient's consultations: a call for additional research on current and new paradigms.

    Science.gov (United States)

    Nguyen, Hanh Thi

    2013-01-01

    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.

    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

    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.

    Because Engineered Trench #3 (ET#3) will be placed in the location previously designated for Slit Trench #12 (ST#12), Solid Waste Management (SWM) requested that the Savannah River National Laboratory (SRNL) determine if the ST#12 limits could be employed as surrogate disposal limits for ET#3 operations. SRNL documented in this Unreviewed Disposal Question Evaluation (UDQE) that the use of ST#12 limits as surrogates for the new ET#3 disposal unit will provide reasonable assurance that Department of Energy (DOE) 435.1 performance objectives and measures (USDOE, 1999) will be protected. Therefore new ET#3 inventory limits as determined by a Special Analysis (SA) are not required.

    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.

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

    Science.gov (United States)

    Biggers, Mandy

    2018-02-01

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

    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

    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

    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

    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.

(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.

    2017-12-12

    Revision 0 of this UDQE addressed the proposal to place Engineered Trench #3 (ET#3) in the footprint designated for Slit Trench #12 (ST#12) and operate using ST#12 disposal limits. Similarly, Revision 1 evaluates whether ET#4 can be located in and operated to Slit Trench #13 (ST#13) disposal limits. Both evaluations conclude that the proposed operations result in an acceptably small risk of exceeding a SOF of 1.0 and approve these actions from a performance assessment (PA) perspective. Because ET#3 will be placed in the location previously designated for ST#12, Solid Waste Management (SWM) requested that the Savannah River National Laboratory (SRNL) determine if the ST#12 limits could be employed as surrogate disposal limits for ET#3 operations. SRNL documented in this Unreviewed Disposal Question Evaluation (UDQE) that the use of ST#12 limits as surrogates for the new ET#3 disposal unit will provide reasonable assurance that Department of Energy (DOE) 435.1 performance objectives and measures (USDOE, 1999) will be protected. Therefore, new ET#3 inventory limits as determined by a Special Analysis (SA) are not required.

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

    Research priorities are often set by academic researchers or the pharmaceutical industry. The interests of patients, carers and clinicians may therefore be overlooked and research questions that matter may be neglected. The aims of this study were to collect uncertainties about the treatment of Type 1 diabetes from patients, carers and health professionals, and to collate and prioritize these uncertainties to develop a top 10 list of research priorities, using a structured priority-setting partnership of patients, carers, health professionals and diabetes organizations, as described by the James Lind Alliance. A partnership of interested organizations was set up, and from this a steering committee of 10 individuals was formed. An online and paper survey was used to identify uncertainties. These were collated, and the steering group carried out an interim priority-setting exercise with partner organizations. This group of uncertainties was then voted on to give a smaller list that went forward to the final priority-setting workshop. At this meeting, a final list of the top 10 research priorities was agreed. An initial 1141 uncertainties were described. These were reduced to 88 indicative questions, 47 of which went out for voting. Twenty-four were then taken forward to a final priority-setting workshop. This workshop resulted in a list of top 10 research priorities in Type 1 diabetes. We have shown that it is possible using the James Lind Alliance process to develop an agreed top 10 list of research priorities for Type 1 diabetes from health professionals, patients and carers. © 2012 The Authors.

    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.

  3. 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.

    2018-01-01

    Via building computational (typically mathematical and computer simulation) models, human performance modeling (HPM) quantifies, predicts, and maximizes human performance, human-machine system productivity and safety. This paper describes and summarizes the five key questions of human performance modeling: 1) Why we build models of human performance; 2) What the expectations of a good human performance model are; 3) What the procedures and requirements in building and verifying a human performance model are; 4) How we integrate a human performance model with system design; and 5) What the possible future directions of human performance modeling research are. Recent and classic HPM findings are addressed in the five questions to provide new thinking in HPM's motivations, expectations, procedures, system integration and future directions.

    2017-11-01

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

    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.

    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.

    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.

    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. This journal 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 papers reporting on qualitative research. This first article describes the key features of qualitative research, provides publications for further learning and reading, and gives an outline of the series.

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

    The third and final discussion paper of the German Network of Health Services Research's (DNVF) "Qualitative Methods Working Group" demonstrates methods for the evaluation and quality of qualitative research in health services research. In this paper we discuss approaches described in evaluating qualitative studies, including: an orientation to the general principles of empirical research, an approach-specific course of action, as well as procedures based on the research-process and criteria-oriented approaches. Divided into general and specific aspects to be considered in a qualitative study quality evaluation, the central focus of the discussion paper undertakes an extensive examination of the process and criteria-oriented approaches. The general aspects include the participation of relevant groups in the research process as well as ethical aspects of the research and data protection issues. The more specific aspects in evaluating the quality of qualitative research include considerations about the research interest, research questions, and the selection of data collection methods and types of analyses. The formulated questions are intended to guide reviewers and researchers to evaluate and to develop qualitative research projects appropriately. The intention of this discussion paper is to ensure a transparent research culture, and to reflect on and discuss the methodological and research approach of qualitative studies in health services research. With this paper we aim to initiate a discussion on high quality evaluation of qualitative health services research. © Georg Thieme Verlag KG Stuttgart · New York.

    Although much research has examined the impact of question generation on students' reading comprehension and learning from lectures, far less research has analysed its influence on how students learn and study science. The present study aims to bridge this knowledge gap. Using a quasi-experimental design, three complete ninth-grade science classes, with a total of 72 students, were randomly assigned to three conditions (groups): (G1) questioning-training by providing prompts; (G2) question-generation without any explicit instruction; and (G3) no question control. Participants' pre-test and post-test self-reported measures of metacognitive knowledge, self-regulation and learning approaches were collected and data analysed with multivariate and univariate analyses of covariance. (a) MANCOVA revealed a significant effect for group; (b) ANCOVAs showed the highest average gains for G1 and statistically significant between-group differences in the two components of metacognition: metacognitive knowledge and self-regulation; and (c) the direction of these differences seemed to vary in each of these components. Question-generation training influenced how students learned and studied, specifically their metacognition, and it had a medium to large effect size, which was somewhat related to the prompts used.

    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.

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the debates of the last round table held at Paris. This meeting gathers representatives of the different actors of the nuclear industry, ministers, public authorities, non governmental organizations who argue the questions asked by peoples from the audience. The topics concern various aspects of waste management, like the quantity of wastes in concern, the reversibility of storages, the monitoring of waste facilities once closed down, the related costs, and the general safety questions about the suitability of the clay formation near the Bure site for the disposal of high-level and long-lived radioactive wastes. A second part of the meeting addresses some remarks about the information of the general public and the decision making process.

    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. ??

  12. 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

  15. The six most essential questions in psychiatric diagnosis: a pluralogue part 1: conceptual and definitional issues in psychiatric diagnosis

    2012-01-01

    Full Text Available Abstract In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1 the nature of a mental disorder; 2 the definition of mental disorder; 3 the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4 the role of pragmatic considerations in the construction of DSM-5; 5 the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6 the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

    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.

    Varadwaj, Arpita; Varadwaj, Pradeep R.; Yamashita, Koichi

    Development of novel semiconductor-based photo-catalytic and -voltaic systems is a major area of research in nanoscience and technologies, and engineering. The process can be either direct or indirect in converting the light energy into electricity. Some of the photovoltaics include the organic, dye-sensitized, and halide perovskite solar cells, among others. Methylammonium lead iodide (CH3NH3PbI3) inorganic-organic hybrid perovskite is one among the many highly valued semiconductors reported till date, comparable with the inorganic cesium lead iodide (CsPbI3) perovskite. These are competitive candidates in the solar energy race. Nevertheless, this study was concentrated on the fundamental understanding of the rational designs of the CH3NH3PbI3 and CsPbI3 supramolecular materials using first-principles calculations, emerged though the self-assembly of the respective building blocks. It therefore addresses the question whether the (CH3NH3PbI3)n and (CsPbI3)n (n =1-10) supramolecular clusters are the consequences of additivity, or non-additive cooperative binding? For addressing this question, the supramolecular properties such as the polarizability, the intermolecular charge transfer, and the binding energy, etc., all w.r.t the cluster size n, are exploited.

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.

    Historical accounts of questioning used in the education process trace back to Socrates. One of the best examples of his use of questioning is found in Plato's "The Republic." Socrates used a series of strategic questions to help his student Glaucon come to understand the concept of justice. Socrates purposefully posed a series of…

    Three experiments test object permanenece in 3 1/2- and 4 1/2-month-old infants, and use an impossible-possible-habituation event format. The 4 1/2-month-olds, and the 3 1/2-month-olds who were fast habituators, look reliably longer at the impossible than at the possible event. Results seriously question Piaget's (1954) claims regarding the age at…

    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.

  6. Nuclear wastes management. 1. round table - geologic disposal as questioned by the public in concern

    International Nuclear Information System (INIS)

    2005-01-01

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the debates of the last round table held at Paris. This meeting gathers representatives of the different actors of the nuclear industry, ministers, public authorities, non governmental organizations who argue the questions asked by peoples from the audience. The topics concern various aspects of waste management, like the quantity of wastes in concern, the reversibility of storages, the monitoring of waste facilities once closed down, the related costs, and the general safety questions about the suitability of the clay formation near the Bure site for the disposal of high-level and long-lived radioactive wastes. A second part of the meeting addresses some remarks about the information of the general public and the decision making process. Finally, five presentations (slides) are attached to these proceedings and treat of: the safety of the disposal in deep geologic formation; the management of spent fuels in Canada; the nuclear wastes R and D in Sweden; the researches and projects in Belgium for the geologic disposal of long-lived radioactive wastes; the results

    Cormier, S.; Prather, E.; Brissenden, G.

    2011-09-01

    We are developing a national archive of multiple-choice questions for use in the Astronomy 101 classroom. These questions are intended to supplement an instructor's implementation of Think-Pair-Share or for their assessment purposes (i.e., exams and homework). We are also developing the Question Complexity Rubric (QCR) to guide members of the Astro 101 teaching and learning community in assisting us with hierarchically ranking questions in this archive based on their conceptual complexity. Using the QCR, a score is assigned to differentiate each question based on the cognitive steps necessary to comprehensively explain the reasoning pathway to the correct answer. The lowest QCR score is given to questions with a reasoning pathway requiring only declarative knowledge. The highest QCR score is given to questions with a reasoning pathway that requires multiple connected cognitive steps. When completed, the online question archive will provide users with the utility to 1) use the QCR to score questions 2) search for and download questions based on topic and/or QCR score, and 3) add their own questions to the archive. Stop by our poster to test your skills at determining question complexity by trying out the QCR with our sample questions.

  10. Pursuing Personal Passion: Learner-Centered Research Mentoring.

    Science.gov (United States)

    Phillips, William R

    2018-01-01

    New researchers often face difficulty finding and focusing research questions. I describe a new tool for research mentoring, the Pursuing Personal Passion (P3) interview, and a systematic approach to help learners organize their curiosity and develop researchable questions aligned with their personal and professional priorities. The learner-centered P3 research interview parallels the patient-centered clinical interview. This paper reviews experience with 27 research mentees over the years 2009 to 2016, using the P3 approach to identify their initial research topics, classify their underlying passions and track the evolution into their final research questions. These researchers usually identified one of three personal passions that provided lenses to focus their research: problem, person, or process. Initial research topics focused on: problem (24%, 6), person (48%, 12) and process (28%, 7). Final research questions evolved into: problem (20%, 5), person (32%, 8) and process (48%, 12). Identification of the underlying passion can lead researchers who start with one general topic to develop it into very different research questions. Using this P3 approach, mentors can help new researchers focus their interests into researchable questions, successful studies, and organized programs of scholarship.

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

    Science.gov (United States)

    Armstrong, Neil

    2017-06-01

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

    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.

    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.)

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

    Full Text Available 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.

    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

  18. Guiding students towards sensemaking: teacher questions focused on integrating scientific practices with science content

    2017-10-01

    Science education reforms articulate a vision of ambitious science teaching where teachers engage students in sensemaking discussions and emphasise the integration of scientific practices with science content. Learning to teach in this way is complex, and there are few examples of sensemaking discussions in schools where textbook lessons and teacher-directed discussions are the norm. The purpose of this study was to characterise the questioning practices of an experienced teacher who taught a curricular unit enhanced with educative features that emphasised students' engagement in scientific practices integrated with science content. Analyses indicated the teacher asked four types of questions: explication questions, explanation questions, science concept questions, and scientific practice questions, and she used three questioning patterns including: (1) focusing students on scientific practices, which involved a sequence of questions to turn students back to the scientific practice; (2) supporting students in naming observed phenomena, which involved a sequence of questions to help students use scientific language; and (3) guiding students in sensemaking, which involved a sequence of questions to help students learn about scientific practices, describe evidence, and develop explanations. Although many of the discussions in this study were not yet student-centred, they provide an image of a teacher asking specific questions that move students towards reform-oriented instruction. Implications for classroom practice are discussed and recommendations for future research are provided.

    Online information seekers make heavy use of websites that accept their natural language questions. This study compared the three types of such websites: social question and answer (Q&A), digital reference services, and ask-an-expert services. Questions reflecting daily life, research, and crisis situations were posed to high use websites of all three types. The resulting answers' characteristics were analyzed in terms of speed, transparency, formality, and intimacy. The results indicate that social Q&A websites excel in speed, ask-an-expert websites in intimacy, and digital reference services in transparency and formality.

    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.

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

    Directory of Open Access Journals (Sweden)

    Pamela Runestad

    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.

    2006-11-01

    Today, it is recommended that planning of decommission should form an integral part of the activities over the life cycle of a nuclear facility. However, no actual international guideline on cost calculations exists at present. Intuitively, it might be tempting to regard costs for decommissioning of a nuclear facility as similar to those of any other plant. However, the presence of radionuclide contamination may imply that the cost is one or more orders of magnitude higher as compared to a corresponding inactive situation, the actual ratio being highly dependent on the level of contamination as well as design features and use of the facility in question. Moreover, the variations in such prerequisites are much larger than for nuclear power plants. This implies that cost calculations cannot be performed with any accuracy or credibility without a relatively detailed consideration of the radiological and other prerequisites. Application of inadequate methodologies especially at early stages has often lead to large underestimations. The goals of the project and the achievements described in the report are as follows: 1) Advice on good practice with regard to: 1a) Strategy and planning; 1b) Methodology selection; 1c) Radiological surveying; 1d) Uncertainty analysis; 2) Techniques for assessment of costs: 2a) Cost structuring; 2b) Cost estimation methodologies; 3) Compilation of data for plants, state of planning, organisations, etc.; 3a) General descriptions of relevant features of the nuclear research facilities; 3b) General plant specific data; 3c) Example of the decommissioning of the R1 research reactor in Sweden; 3d) Example of the decommissioning of the DR1 research reactor in Denmark. In addition, but not described in the present report, is the establishment of a Nordic network in the area including an internet based expert system. It should be noted that the project is planned to exist for at least three years and that the present report is an interim one

    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.

    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.

    The Veterans Health Administration does not routinely collect and document sexual orientation and gender identity (SOGI) data, despite existing health disparities among sexual and gender minority Veterans. Because of the legacy of previous Department of Defense (DoD) policies that prohibited disclosure of sexual or gender minority identities among active duty personnel, Veterans may be reluctant to respond to SOGI questions. This population-based study assesses item nonresponse to SOGI questions by Veteran status. This is a secondary analysis of data from a population-based sample of adults in 20 US states that elected to administer a SOGI module in the 2014 Behavioral Risk Factor Surveillance System survey. Prevalence of SOGI refusals and responses of "don't know" were compared for Veterans and non-Veterans. Veterans (n=22,587) and non-Veterans (n=146,475) were surveyed. Nearly all Veteran respondents (≥98%) completed the SOGI questions, with 95.4% identifying as heterosexual, 1.2% as gay or lesbian, 1.2% as bisexual, and 0.59% as transgender. A significantly lower proportion of Veterans than non-Veterans refuse to answer sexual orientation (1.5% vs. 1.9%). There was no difference between Veterans and non-Veterans in responses for gender identity. Veterans are just as likely as non-Veterans to complete SOGI items in survey research. Asking Veterans about SOGI is unlikely to yield significant nonresponse. These data suggest that future research should investigate Veterans' perspectives on being asked about SOGI in research settings and as part of routine clinical care.

    Students' ability in solving chemical problems is seen from their ability to solve chemicals' non-routine problems. It is due to learning faced directly on non-routine problems will generate a meaningful learning for students. Observations in Banjarmasin Public High School 1 (SMA Negeri 1 Banjarmasin) showed that students did not give the expected results when they were given the non-routine problems. Learning activities by emphasizing problem solving was implemented based on the existence of knowledge about cognition and regulation of cognition. Both of these elements are components of metacognition. The self-directed question is a strategy that involves metacognition in solving chemical problems. This research was carried out using classroom action research design in two cycles. Each cycle consists of four stages: planning, action, observation and reflection. The subjects were 34 students of grade XI-4 at majoring science (IPA) of SMA Negeri 1 Banjarmasin. The data were collected using tests of the students' ability in problem solving and non-tests instrument to know the process of implementation of the actions. Data were analyzed with descriptivequantitativeand qualitative analysis. The ability of students in solving chemical problems has increased from an average of 37.96 in cycle I became 61.83 in cycle II. Students' ability to solve chemical problems is viewed based on their ability to answer self-directed questions. Students' ability in comprehension questions increased from 73.04 in the cycle I became 96.32 in cycle II. Connection and strategic questions increased from 54.17 and 16.50 on cycle I became 63.73 and 55.23 on cycle II respectively. In cycle I, reflection questions were 26.96 and elevated into 36.27 in cycle II. The self-directed questions have the ability to help students to solve chemical problems through metacognition questions. Those questions guide students to find solutions in solving chemical problems.

    Full Text Available Children’s questions are an indicator of active cognitive perception of reality. Questions but not answers are relevant in revealing a child’s mental life, consciousness and thinking. The lack of question-asking skills can hinder learning, searching and exploration in children. To determine in 7- and 8-year-old school children the common and variable peculiarities of designing a search process for necessary information concerning an unknown object by volitionally formulated questions, as well as the dynamics of the questioning process throughout a school year. The study was based on an experimental methodology, codenamed Guess what there is in the box, and was conducted in four schools in Cheboksary. The sample comprised 158 primary school first-graders who took part in a confirmatory experiment twice, once in September and once in May. The research showed that 96.3% of the questions asked were search questions. Only 30% of the first-graders initiated their searching activities of their own will without having to resort to the given search algorithm, while 70% did not begin asking questions without outside stimulation. The analysis of the dynamics of children’s question-asking behavior exhibited a tendency to decrease in a number of questions asked over the course of the school year. Primary school children need psychological and pedagogical scaffolding aimed at developing a question-asking behavior as a form of cognitive activity to achieve a possible age potential in development.

    2011-01-01

    For the last two years we have been developing an online national archive of multiple-choice questions for use in the Astro 101 classroom. These questions are intended to either supplement an instructor's implementation of Think-Pair-Share or be used for assessment purposes (i.e. exams and homework). In this talk we will describe the development, testing and implementation of the Question Complexity Rubric (QCR), which is designed to guide the ranking of questions in this archive based on their conceptual complexity. Using the QCR, a score is assigned to differentiate each question based on the cognitive steps necessary to comprehensively explain the reasoning pathway to the correct answer. The lowest QCR score is given to questions with a reasoning pathway requiring only declarative knowledge whereas the highest QCR score is given to questions that require multiple pathways of multi-step reasoning. When completed, the online question archive will provide users with the utility to 1) search for and download questions based on subject and average QCR score, 2) use the QCR to score questions, and 3) add their own questions to the archive. We will also discuss other potential applications of the QCR, such as how it informs our work in developing and testing of survey instruments by allowing us to calibrate the range of question complexity. This material is based upon work supported by the National Science Foundation under Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS).

    Full Text Available Background: Relatives often lack important information about intensive care unit patients. Research on ways to improve family satisfaction in the ICU has become a crucial point in ICU quality improvement research. Objective: The aim of this study is to develop and analyze a list of commonly asked questions from relatives of patients in the intensive care unit in Arabic countries. This list might help families to determine which questions they want to ask and help them in decision-making process in emergency situations of their critically ill relatives. Methods: This study was a prospective double center study. It took place in the ICUs of two hospitals in Arabic countries: Egypt and Kingdom of Saudi Arabia. Alexandria University Main Hospital in Egypt and the ICU of King Fahad specialist Hospital in Dammam in Saudi Arabia. Data collection was done by reporting of Questions asked by the relatives of ICU patients during daily interview. The list of questions generated was checked to identify questions that could be eliminated. The remaining questions were categorized into 9 different groups: diagnosis, treatment, prognosis, comfort, patient interaction, family, mortality, post-ICU management and other questions. WE ranked the questions in the preliminary list through ICU staff, patients families and the patient themselves. Results: 115 Health care professional (34 physicians and 81 nurses participated in the data collection, the questions recorded were 2240 questions. It was found that about 1750 questions (78.12% were duplicated or not clear. The remaining 490 questions were classified into different categories. The same 115 Health care professional (34 physicians and 81 nurses who shared in the collection of data also shared in the ranking of the questions. 128 first degree relatives shared in the evaluation of the relevance of questions as well as 62 patients after they have been cured and before their discharge from ICU.A list was created

    The SAFARI-1 reactor is a tank-in-pool MTR type research reactor operated at a nominal core power of 20 MW. It operates exclusively in the single phase liquid water regime with nominal water and fuel temperatures not exceeding 100 deg. C. RELAP/SCDAPSIM/MOD3.4 is a Best Estimate Code for light water reactors as well as for low pressure transients, as part of the code validation was done against low pressure facilities and research reactor experimental data. The code was used to simulate SAFARI-1 in normal and abnormal operation and validated against the experimental data in the plant and was used extensively in the upgrading of the Safety Analysis Report (SAR) of the reactor. The focus of the following study is the safety analysis of the SAFARI-1 research reactor and describes the thermal hydraulic modelling and analysis approach. Particular emphasis is placed on the modelling detail, the application of the no-boiling rule and predicting the Onset of Nucleate Boiling and Departure from Nucleate Boiling under Loss of Flow conditions. Such an event leads the reactor to switch to a natural convection regime which is an adequate mode to maintain the clad and fuel temperature within the safety margin. It is shown that the RELAP/SCDAPSIM/MOD3.4 model can provide accurate predictions as long as the clad temperature remains below the onset of nucleate boiling temperature and the DNB ratio is greater than 2. The results are very encouraging and the model is shown to be appropriate for the analysis of SAFARI-1 research reactor. (authors)

    Retrieval practice improves retention of information on later tests. A question remains: When should retrieval occur during learning-interspersed throughout study or at the end of each study period? In a lab experiment, an online experiment, and a classroom study, we aimed to determine the ideal placement (interspersed vs. at-the-end) of retrieval practice questions. In the lab experiment, 64 subjects viewed slides about APA style and answered short-answer practice questions about the content or restudied the slides (restudy condition). The practice questions either appeared 1 every 1-2 slides (interspersed condition), or all at the end of the presentation (at-the-end condition). One week later, subjects returned and answered the same questions on a final test. In the online experiment, 175 subjects completed the same procedure. In the classroom study, 62 undergraduate students took quizzes as part of class lectures. Short-answer practice questions appeared either throughout the lectures (interspersed condition) or at the end of the lectures (at-the-end condition). Nineteen days after the last quiz, students were given a surprise final test. Results from the 3 experiments converge in demonstrating an advantage for interspersing practice questions on the initial tests, but an absence of this advantage on the final test.

    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.

    The authors examined the usefulness of a commercially available Step 1 question bank as a formative academic support tool throughout organ-based modules in an integrated preclinical medical curriculum. The authors also determined the extent to which correlation between question bank utilization and academic metrics varied with Medical College Admission Test (MCAT) scores. In 2015, a cohort of 185 first-year medical students at University of Alabama School of Medicine were provided with 18-month full access to a commercially available Step 1 question bank of over 2,100 items throughout organ-based modules, although there were no requirements for use. Data on student use of the question bank were collected via an online administrative portal. Relationships between question bank utilization and academic outcomes including exams, module grades, and United States Medical Licensing Examination (USMLE) Step 1 were determined using multiple linear regression. MCAT scores and number of items attempted in the question bank significantly predicted all academic measures, with question bank utilization as the stronger predictor. The association between question bank utilization and academic outcome was stronger for individuals with lower MCAT scores. The findings elucidate a novel academic support mechanism that, for some programs, may help bridge the gap between holistic and mission-based admissions practices and a residency match process that places a premium on USMLE exam scores. Distributed formative use of USMLE Step 1 practice questions may be of value as an academic support tool that benefits all students, but particularly those entering with lower MCAT scores.

  2. A review of state-of-the-art stereology for better quantitative 3D morphology in cardiac research.

    2010-01-01

    The aim of stereological methods in biomedical research is to obtain quantitative information about three-dimensional (3D) features of tissues, cells, or organelles from two-dimensional physical or optical sections. With immunogold labeling, stereology can even be used for the quantitative analysis of the distribution of molecules within tissues and cells. Nowadays, a large number of design-based stereological methods offer an efficient quantitative approach to intriguing questions in cardiac research, such as "Is there a significant loss of cardiomyocytes during progression from ventricular hypertrophy to heart failure?" or "Does a specific treatment reduce the degree of fibrosis in the heart?" Nevertheless, the use of stereological methods in cardiac research is rare. The present review article demonstrates how some of the potential pitfalls in quantitative microscopy may be avoided. To this end, we outline the concepts of design-based stereology and illustrate their practical applications to a wide range of biological questions in cardiac research. We hope that the present article will stimulate researchers in cardiac research to incorporate design-based stereology into their study designs, thus promoting an unbiased quantitative 3D microscopy.

    This article is the fourth of six articles addressing systematic reviews in animal agriculture and veterinary medicine. Previous articles in the series have introduced systematic reviews, discussed study designs and hierarchies of evidence, and provided details on conducting randomized controlled trials, a common design for use in systematic reviews. This article describes development of a review protocol and the first two steps in a systematic review: formulating a review question, and searching the literature for relevant research. The emphasis is on systematic reviews of questions related to interventions. The review protocol is developed prior to conducting the review and specifies the plan for the conduct of the review, identifies the roles and responsibilities of the review team and provides structured definitions related to the review question. For intervention questions, the review question should be defined by the PICO components: population, intervention, comparison and outcome(s). The literature search is designed to identify all potentially relevant original research that may address the question. Search terms related to some or all of the PICO components are entered into literature databases, and searches for unpublished literature also are conducted. All steps of the literature search are documented to provide transparent reporting of the process. © 2014 Blackwell Verlag GmbH.

    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

    By use of a systematic approach, the aim of this project was to survey a group of colorectal specialists and reach a consensus on the research questions of highest importance in terms of clinical care. A modified Delphi process was performed. In Round 1 research questions were solicited from members of The American Society of Colon and Rectal Surgeons. A review group categorized the results, combined similar questions, and presented them to The American Society of Colon and Rectal Surgeons membership in Round 2 for prioritizing according to importance. In Round 3 the 50 questions with the highest scores in Round 2 were reranked by The American Society of Colon and Rectal Surgeons membership to produce the 20 highest-priority research questions. A total of 203 respondents in Round 1 submitted 746 questions. The review team reduced these to 105 individual questions encompassing 21 topics in colorectal surgical practice. In Rounds 2 and 3, 399 and 360 respondents, respectively, prioritized the questions presented. The final 20 items included 14 questions related to colorectal cancer, and 6 were on benign disease topics. The research agenda produced by this study reflects the clinical issues of greatest importance to colorectal surgeons. The results are of potential benefit to researchers, funding organizations, medical journals, and ultimately, patients.

    Safety demonstration tests using the HTTR are to be conducted from the FY2002 to verify the inherent safety features and to improve the safety design and evaluation technologies for HTGRs, as well as to contribute to not only the commercial HTGRs but also the research and development for the VHTR that is one of the Generation IV reactor candidates. This paper describes the reactivity insertion test (SR-3), the coolant flow reduction test by tripping of gas circulators (S1C-3, S2C-3), and the partial flow loss of coolant test (SF-2) planned in March 2005 with their detailed test method, procedure and results of pre-test analysis. From the analytical results, it was verified that the negative reactivity feedback effect of the core brings the reactor power safely to a stable level without a reactor scram. (author)

    Full Text Available This research aims to find out the typical categories of answers to Yes/No questions most used by students at selected Public Senior High Schools in Medan, Indonesia. These schools were classified into top favorite, medium favorite and non-favorite schools. Through a stratified clustered random sampling technique, six schools were chosen consisting of two schools from each classification. A number of 40 students were chosen from three class X, three class XI and three class XII at each of the six chosen schools, making a total sample of 720 students with 360 sets of dialogue scripts. Data was collected through documentation-recording dialogues. The data was transcribed and analyzed by descriptive analysis. The results of the research showed that: 1 the categories of the students’ answers to the Yes/No questions were distributed variously in terms of the six models. However, the distribution of the answers was not proportionally equal amongst all the models, 2 the dominant distribution of the answers was the third model with the formula Yes/No+additional information such as confirming, supporting, etc., reaching 37% of the total answers, whilst the least common models were the sixth and fourth categories respectively, which had 1% and 3% of the answers respectively, and finally 3 there was no significant difference in the distribution of the students’ answers in terms of the class of school whether top favorite, medium favorite or non-favorite. In conclusion, the ways to answer Yes/No questions need to be developed amongst students by their teachers by teaching and learning using natural, real life-like situations and in contextual ways.

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

    Full Text Available This study is aimed to elaborate the interlanguage interference of the difficulties which are faced by 40 second year students of MA As Soorkaty Salatiga in academic year of 2004-2005 in building question sentences and the sources of difficulties. The research is conducted by such kind of test. The total number of test are 20 items, consist of 5 yes-no questions, 5 W-H questions, and 10 tag questions which is done in a written essay form. Based on the analysis, the result shows some conclusions. Firstly, the researcher finds the types of difficulties problems are faced by the students in building question mastery, such as: (1 building yes-no question sentences in translation the word “apakah”, that is related with the use of to be. (2 Building interrogative word question sentences in translation the words “apa”, “kapan”, “milik siapa”, etc. That are related with the use of “what”, “when”, “whose”, etc. (3 Completing the tag question sentences with the proper auxiliary based on tense of the sentences. The most difficulties in building question sentences are especially in yes-no question form by using the word “apakah”. In the term of interlanguage, the students’ errors are mostly included in expressing meaning by the words and grammar of the first language. The source of difficulties which have been analyzed are mostly caused by inter lingual and intra lingual transfer.

    Full Text Available This paper examines interviewer-respondent interaction in the collection of demographic data. Conversation analysis (CA makes transparent the interaction between an interviewer and 25 respondents on a question about pregnancy and birth timing in an Australian telephone survey, Negotiating the Life Course. The analysis focuses on the troubles that occur and the work interviewers do to fit respondents' answers to the survey researcher's categories. Interviewers are shown to act as mediators in difficult interaction, with responses often distorted by question format, the imperative of achieving an allowed response, and the need to keep the respondent in the survey.

    2018-05-01

    This research aims to know how students’ argumentative skills improved by applying teacher’s questioning techniques and argumentative assessment through collaborative action research between college student who did teaching practicum, biology teacher as tutor teacher, and lecturers. The action research was done in three cycles involving one class consisted of 36 eleventh graders. Lesson plans were developed collaboratively, and teaching practices were by the student teacher. In the reflective phase prior to the first cycle, learning processes were dominated by the teacher, hence students did not have sufficient opportunity to argue. Students were divided into two, 14 students were grouped as low achievement (LA) and 22 students were the high achievement (HA). Teacher questions and students’ responses were furtherly coded and interpreted following the validated rubric of level of argumentation. A divergent essay as an argumentative assessment was also tested to students at the end of each cycle. At the end of the third cycle, HA and LA students showed a significant change in argumentative skills responded the teacher’s questions. However, only four LA students who actively argued. Students from HA groups also showed the improvement on the level of argumentation, where they move from level 1 to 3.

    Graphical abstract: - Highlights: • The enthalpy of formation of 1,1,3,3-tetramethylguanidinium nitrate was determined by combustion calorimetry. • The cohesive energy of liquid 1,1,3,3-tetramethylguanidinium nitrate was evaluated. • The crystal structure of 1,1,3,3-tetramethylguanidinium nitrate was determined by single crystal X-ray diffraction. • Δ f H m o (l/g) of 1,1,3,3-tetramethylguanidine (tmg) were obtained by solution and Calvet calorimetry. • Δ f H m o (g) calculated by the W1-F12 procedure was in excellent agreement with the corresponding experimental value. - Abstract: Considerable efforts have recently been made to investigate how the structure of protic ionic liquids determines some of their most important properties for technological applications (e.g. low vapour pressure, conductivity). In contrast, the assessment of cohesive energies (which are also linked to those properties) based on thermodynamic results is still practically unexplored. This problem is addressed here for 1,1,3,3-tetramethylguanidinium nitrate, [Htmg][NO 3 ], through a combination of experimental and computational chemistry results at the reference temperature of 298.15 K. The standard molar enthalpies of formation, Δ f H m o ([Htmg][NO 3 ],cr)=-(311.8±2.3)kJ·mol -1 , and fusion, Δ fus H m o ([Htmg][NO 3 ])=16.2±3.8kJ·mol -1 , of solid 1,1,3,3-tetramethylguanidinium nitrate (form I polymorph) were obtained by combustion and differential scanning calorimetry, respectively. From these results Δ f H m o ([Htmg][NO 3 ],l)=-(295.6±4.4)kJ·mol -1 could be derived. Also determined were the standard molar enthalpies of formation, Δ f H m o (tmg, l)=7.7±2.8kJ·mol -1 , and vaporisation, Δ vap H m o (tmg,l)=50.0±1.2kJ·mol -1 , of 1,1,3,3-tetramethylguanidine, by reaction solution and Calvet-drop microcalorimetry, respectively, leading to Δ f H m o (tmg,g)=57.7±3.0kJ·mol -1 . This result is in excellent agreement with Δ f H m o (tmg,g)=58.4±4.0kJ·mol -1

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

  6. Power dynamics and questioning in elementary science lessons

    Science.gov (United States)

    Reinsvold, Lori Ann

    Discourse interactions between a teacher and students in an inquiry-based fourth-grade science classroom were analyzed to investigate how power dynamics and questioning strategies within elementary science lessons help support students in building their science understanding. Five inquiry-based classroom sessions were observed; verbal interactions were audio- and video-recorded. Research data consisted of observation transcripts, teacher interviews, student work, and instructional materials. Analyses were conducted on the frequencies of utterances, participation roles, power categories, and questioning categories. Results revealed that when students used more frequent power, (a) no significant differences were noted between frequencies of teacher and student talk, (b) the teacher posed more questions than did the students, and (c) students explained what they knew and asked questions to clarify their understanding. When the teacher used more frequent power, she asked questions to provide students opportunities to negotiate investigative processes and explain what they knew and how they knew it. Evidence of student understanding of the science concepts was found in how students used subject matter to discuss what they knew and how they knew it. Pre-service and in-service teachers should be encouraged to consider how their use of power and questioning strategies can engage students to reflect on how they build understanding of science concepts. Teachers can use Professional Learning Communities to reflect on how their practice engages students. Future research should be employed to observe classrooms across an entire school year to determine how power and questioning dynamics flow among students and teachers and change over time. Research can also be used to understand the influence of gender and culture on power and questioning dynamics in classroom settings.

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

  8. Rhetorical questions or rhetorical uses of questions?

    2016-12-01

    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.

    2018-02-01

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

    2017-12-01

    The term of water-energy -food nexus has gained increasing attention in the research and policy making communities as the security of water, energy and food becomes severe under changing environment. Ignorance of their closely interlinkages accompanied by their availability and service may result in unforeseeable, adverse consequences. This paper comprehensively reviews the state-of-the-art in the field of water-energy-food, with a focus on concepts, research questions and methodologies. First, two types of nexus definition are compared and discussed to understand the essence of nexus research issues. Then, three kinds of nexus research questions are presented, including internal relationship analysis, external impact analysis, and evaluation of the nexus system. Five nexus modelling approaches are discussed in terms of their advantages, disadvantages and application, with an aim to identify research gaps in current nexus methods. Finally, future research areas and challenges are discussed, including system boundary, data uncertainty and modelling, underlying mechanism of nexus issues and system performance evaluation. This study helps bring research efforts together to address the challenging questions in the nexus and develop the consensus on building resilient water, energy and food systems.

    This paper is devoted to three propositions: (1) Some of the most basic questions in heavy-quark physics remain unanswered; (2) Charmonium physics is the best place to address those questions at the required level of precision; (3) A tau-charm factory, with a commensurate state-of-the-art detector, are mandatory for doing the job. While open-charm and tau physics will certainly be done at beauty factories, charmonium physics will not. It must, therefore, form an important part of the physics program at a tau charm factory. With this as an introduction, the author then reviews the status of charmonium studies at this point, and ongoing work, with its projected weaknesses

  16. 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

    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. The second article focused on context, research questions and designs, and referred to publications for further reading. This third article addresses FAQs about sampling, data collection and analysis. The data collection plan needs to be broadly defined and open at first, and become flexible during data collection. Sampling strategies should be chosen in such a way that they yield rich information and are consistent with the methodological approach used. Data saturation determines sample size and will be different for each study. The most commonly used data collection methods are participant observation, face-to-face in-depth interviews and focus group discussions. Analyses in ethnographic, phenomenological, grounded theory, and content analysis studies yield different narrative findings: a detailed description of a culture, the essence of the lived experience, a theory, and a descriptive summary, respectively. The fourth and final article will focus on trustworthiness and publishing qualitative research.

  1. 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.

    Recent data show US adolescents are engaging in sexual activity at earlier ages; however, little is known about young teens' sexual attitudes and behaviors. Examining teens' questions in sex education classes may provide insight into these attitudes and behaviors. Quasi cohort study Parochial middle school sex education classes 5(th) through 8(th) graders Students' anonymous written questions submitted at the outset of sex education classes between 2003 and 2005. Questions were classified into topic categories. Three additional variables were then coded for each question. Ethics/guidance questions included requests for advice or value judgments. Prohibited questions included the topics homosexuality, abortion, masturbation, and contraception. "Red flag" questions were those that suggested consideration of or engagement in sexual behavior. Among 473 questions submitted by 410 students, the most popular topics for 5(th)/6(th) graders were pregnancy and puberty, and for 7(th)/8(th) graders puberty and menstruation. 41 questions (8.6%) were prohibited. 29 questions (6.2%) asked about ethics/guidance. 18 questions (3.81%) were coded as red flag questions. A chi-square analysis showed that 5(th)/6(th) graders asked more questions in the ethics/guidance (8.3% versus 3.64%) and red flag question categories (5.53% versus 1.82%) (P < 0.05) than 7(th)/8(th) graders. Although provocative questions represent a minority of these middle students' queries, these requests suggest the urgency of providing appropriate guidance to young teens, given the risks of early sexual activity. The role of school education programs, physicians and parents in addressing questions of this sort should be considered.

  3. Relativity and the question of discretization in astronomy

    Edelen, Dominic G B

    1970-01-01

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

    To facilitate the training of plastic surgery residents, we analyzed a knowledge-based curriculum for plastic and reconstructive surgery of the lower extremity. The Plastic Surgery In-Service Training Exam (PSITE) is a commonly used tool to assess medical knowledge in plastic surgery. We reviewed the lower extremity content on 6 consecutive score keys (2008-2013). Questions were classified by taxonomy, anatomy, and subject. Answer references were quantified by source and relative year of publication. Totally, 107 questions related to the lower extremity (9.1% of all questions) and 14 questions had an associated image (13.1%). Questions required decision making (49%) over interpretation (36%) and direct recall (15%) skills (p < 0.001). Conditions of the leg (42.1%) and thigh (24.3%) constituted most of the questions. Subject matter focused on flap reconstruction (38.3%), nerve injury (8.4%), and congenital deformity (6.5%). Analysis of 263 citations to 66 unique journals showed that Plastic and Reconstructive Surgery (54.9%) was the highest yield primary source. The median year of publication relative to PSITE administration was 6 (range: 1-58) with a mode of 2 years. Plastic Surgery by Mathes et al. was the most referenced textbook (21.9%). These data establish a benchmark for lower extremity training during plastic surgery residency. Study efforts focused on the most common topics and references will enhance trainee preparation for lower extremity PSITE questions. Copyright © 2015 Association of Program Directors in Surgery.

  9. Research socially responsible: may we speak of a Mode 3 knowledge production? - DOI: 10.3395/reciis.v2i1.145en

    2008-10-01

    Full Text Available A collateral effect of the globalization of the economy is the “globalization of science”, in the sense that part of it works at the service of the global economy. Part of the scientific production thus appears to be linked to the needs of the global markets. However, in the past 20 years, new alternative ways of “doing science” have emerged throughout the world whose most important characteristic is their intimate relationship with the solution of felt problems linked to local or regional communities. Although they share some of the characteristics of “Mode 2” research, as defined by GIBBONS et al (1994, they differ drastically in the sense that they really are socially responsible. These new forms are a response to the need to make scientific research more participative, more closely linked to the groups that would be affected by its results, incorporating thus in the decision-making process, not only the researchers themselves, but also those agents that would be directly affected by its products. This paper reflects upon an experience that currently takes place in Mexico, where research is intimately linked to the learning function, and is strongly rooted into the New Information and Communication Technologies (NICT. This form of doing “research in the service of humanity” is consistent with an alternative definition of development that is not necessarily linked to “growth”, as traditionally reflected in economic statistics. Development is not a question of what one has, but of what one can do with what one has. Development is the ability and desire to use what is available to continuously improve one’s quality of life (ACKOFF, 1974. Projects like the one described here provide a sense of progress in the right direction, in the direction of true development. We call this way of knowledge generation “Mode 3”, to differentiate it from Mertonian (Mode 1 and Gibbons’ (Mode 2 way of doing science. Mode 3 is a mode of

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

    Directory of Open Access Journals (Sweden)

    Ayoade Ejiwale Okanlawon

    2012-04-01

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

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

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

    2010-01-01

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

  16. Part I. Analyzing the distribution of gas law questions in chemistry textbooks. Part II. Chlorine-35 NQR spectra of group 1 and silver dichloromethanesulfonates

    Science.gov (United States)

    Gillette, Gabriel

    Part I. Two studies involving the gas law questions in eight high school and Advanced Placement/college chemistry textbooks were performed using loglinear analysis to look for associations among six variables. These variables included Bloom's Taxonomy (higher-order, lower-order), Book Type (high school, college), Question Format (multiple-choice, problem, short answer), Question Placement (in-chapter, end-of-chapter, test bank), Representation (macroscopic, microscopic, symbolic), and Arkansas Science Standard (conceptual, mathematical; gas laws, pressure conversion, stoichiometry). The first study, involving the conceptual gas law questions, found the Book Type and Question Placement variables had the biggest impact, each appearing in 5 of the 11 significant associations. The second study, involving the mathematical gas law questions, found the Question Placement had the biggest impact, appearing in 7 of the 11 significant associations, followed by Book Type and the Arkansas Science Standard variables, which appeared in 5 of the 11 significant associations. These studies showed that compared to the high school books, college books have fewer multiple-choice questions (compared to short-answer and problem questions), fewer in-chapter questions (compared to end-of-chapter and test bank questions), fewer questions in the chapters and more questions at the end of the chapters and fewer multiple-choice questions in and at the end of the books and more multiple-choice questions in the test banks. Part II. The dichloromethanesulfonate salts of several +1 charged cations, M+Cl2CHSO3 - (M = Li, Na, K, Rb Ag, Cs Tl) were synthesized and studied by 35Cl nuclear quadrupole resonance (NQR). Dichloromethanesulfonic acid was prepared by the methanolysis of dichloromethanesulfonyl chloride, which was neutralized with the metal carbonates to produce the corresponding metal dichloromethanesulfonate salts. This study completed the NQR investigation of the family of chloroacetates

    2009-01-01

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

    New psychoactive substances (NPS) continue to emerge; however, few surveys of substance use ask about NPS use. Research is needed to determine how to most effectively query use of NPS and other uncommon drugs. To determine whether prevalence of self-reported lifetime and past-year use differs depending on whether or not queries about NPS use are preceded by "gate questions." Gate questions utilize skip-logic, such that only a "yes" response to the use of specific drug class is followed by more extensive queries of drug use in that drug class. We surveyed 1,048 nightclub and dance festival attendees (42.6% female) entering randomly selected venues in New York City in 2016. Participants were randomized to gate vs. no gate question before each drug category. Analyses focus on eight categories classifying 145 compounds: NBOMe, 2C, DOx, "bath salts" (synthetic cathinones), other stimulants, tryptamines, dissociatives, and non-phenethylamine psychedelics. Participants, however, were asked about specific "bath salts" regardless of their response to the gate question to test reliability. We examined whether prevalence of use of each category differed by gate condition and whether gate effects were moderated by participant demographics. Prevalence of use of DOx, other stimulants, and non-phenethylamine psychedelics was higher without a gate question. Gate effects for other stimulants and non-phenethylamine psychedelics were larger among white participants and those attending parties less frequently. Almost one in ten (9.3%) participants reporting no "bath salt" use via the gate question later reported use of a "bath salt" such as mephedrone, methedrone, or methylone. Omitting gate questions may improve accuracy of data collected via self-report.

    Students’ concept comprehension in three-tier multiple-choice diagnostic test related to student confidence level. The confidence level related to certainty and student’s self-efficacy. The purpose of this research was to find out students’ certainty in misconception test. This research was quantitative-qualitative research method counting students’ confidence level. The research participants were 484 students that were studying acid-base and equilibrium solubility subject. Data was collected using three-tier multiple-choice (3TMC) with thirty questions and students’ questionnaire. The findings showed that #6 item gives the highest misconception percentage and high student confidence about the counting of ultra-dilute solution’s pH. Other findings were that 1) the student tendency chosen the misconception answer is to increase over item number, 2) student certainty decreased in terms of answering the 3TMC, and 3) student self-efficacy and achievement were related each other in the research. The findings suggest some implications and limitations for further research.

    2012-07-01

    Full Text Available Abstract In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1 the nature of a mental disorder; 2 the definition of mental disorder; 3 the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4 the role of pragmatic considerations in the construction of DSM-5; 5 the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6 the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

    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.

The article describes the general mapping, prioritizing, reconciling, and updating approach: (1) identifying gaps in the maternal health research using published systematic reviews and formulating research questions, (2) prioritizing questions using Delphi method, (3) reconciling identified research priorities with the existing literature (i.e., searching of ongoing trials in trials registries), (4) updating the process. A comprehensive search of Cochrane systematic reviews published or updated from January 2006 to March 2011 was performed. We evaluated the "Implications for Research" section to identify gaps in the research. Our search strategy identified 695 references; 178 systematic reviews identifying at least one research gap were used. We formulated 319 research questions, which were classified into 11 different categories based on the direct and indirect causes of maternal mortality: postpartum hemorrhage, abortion, hypertensive disorders, infection/sepsis, caesarean section, diabetes, pregnancy prevention, preterm labor, other direct causes, indirect causes, and health policies and systems. Most research questions concerned the effectiveness of clinical interventions, including drugs (42.6%), nonpharmacologic interventions (16.3%), and health system (14.7%). It is possible to identify gaps in the maternal health research by using this approach. Copyright © 2013 Elsevier Inc. All rights reserved.

    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.

    To (1) test whether patient attitudes toward intake forms at three Midwestern outpatient clinics are significantly more negative among those who are asked to complete SOGI questions versus those who are not; and (2) gain an in-depth understanding of patient concerns about SOGI questions. Data were collected between 6/29/2015 and 2/29/2016 from new patients (N = 491) who presented at three outpatient clinics in a large academic medical center. This study was originally a quality improvement project, and later, institutional review board approval was obtained for secondary data analysis. Two-stage mixed-methods study. (1) Experimental: New patients at three sites were randomly assigned to complete either routine intake forms (control) or routine intake forms with SOGI questions (experimental); and (2) qualitative: interviews with patients who responded negatively to SOGI questions. There were no significant differences in patient attitudes between experimental and control groups (p > .05). Of those who received SOGI questions, only 3 percent reported being distressed, upset, or offended by the SOGI questions. Collection of SOGI data as a part of the routine clinical patient intake process is not distressing to 97 percent of patients who are heterosexual, cisgender, and older than 50 years. © Health Research and Educational Trust.

    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...

  13. Problem-based learning through field investigation: Boosting questioning skill, biological literacy, and academic achievement

    2018-01-01

    Biology learning emphasizes problem-based learning as a learning strategy to develop students ability in identifying and solving problems in the surrounding environment. Problem identification skills are closely correlated with questioning skills. By holding this skill, students tend to deliver a procedural question instead of the descriptive one. Problem-based learning through field investigation is an instruction model which directly exposes the students to problems or phenomena that occur in the environment, and then the students design the field investigation activities to solve these problems. The purpose of this research was to describe the improvement of undergraduate biology students on questioning skills, biological literacy, and academic achievement through problem-based learning through field investigation (PBFI) compared with the lecture-based instruction (LBI). This research was a time series quasi-experimental design. The research was conducted on August - December 2015 and involved 26 undergraduate biology students at the State University of Malang on the Freshwater Ecology course. The data were collected during the learning with LBI and PBFI, in which questioning skills, biological literacy, and academic achievement were collected 3 times in each learning model. The data showed that the procedural correlative and causal types of questions are produced by the students to guide them in conducting investigations and problem-solving in PBFI. The biological literacy and academic achievement of the students at PBFI are significantly higher than those at LBI. The results show that PBFI increases the questioning skill, biological literacy, and the academic achievement of undergraduate biology students.

    Australia is facing a primary health care workforce shortage. To inform primary health care (PHC) workforce policy reforms, reflection is required on ways to strengthen the evidence base and its uptake into policy making. In 2008 the Australian Primary Health Care Research Institute funded the Australian Health Workforce Institute to host Professor James Buchan, Queen Margaret University, UK, an expert in health services policy research and health workforce planning. Professor Buchan's visit enabled over forty Australian PHC workforce mid-career and senior researchers and policy stakeholders to be involved in roundtable policy dialogue on issues influencing PHC workforce policy making. Six key thematic questions emerged. (1) What makes PHC workforce planning different? (2) Why does the PHC workforce need to be viewed in a global context? (3) What is the capacity of PHC workforce research? (4) What policy levers exist for PHC workforce planning? (5) What principles can guide PHC workforce planning? (6) What incentives exist to optimise the use of evidence in policy making? The emerging themes need to be discussed within the context of current PHC workforce policy reforms, which are focussed on increasing workforce supply (via education/training programs), changing the skill mix and extending the roles of health workers to meet patient needs. With the Australian government seeking to reform and strengthen the PHC workforce, key questions remain about ways to strengthen the PHC workforce evidence base and its uptake into PHC workforce policy making.

    The purpose of this study was to describe the use of an Internet delivered question and answer column among patients with schizophrenia. The column was developed for research purposes. The study sample consisted of patients (N = 100) admitted to acute inpatient psychiatric care in two hospital districts. Descriptive data were collected from the column to which a nurse replied within 3 days and analysed using qualitative content analysis. The column had four to five questions weekly. The most common age of users was 18-24 years, and the gender distribution was almost equal. Column use was heaviest among students (44%) and least among unemployed people (19%). Out of 85 questions or comments sent to the column, 25 (29%) were related to program training and the remaining 60 (71%) were related to medication (31%), illness and tests (25%), other questions or comments (9%), daily life and coping with it (4%), and places to receive treatment (2%). An Internet delivered question and answer column can be included in the care of patients with schizophrenia. However, it requires a new type of basic and additional education in the field of mental health care in order for nurses to be able to provide nursing via the Internet forum.

    M. Hakan Türkçapar

    2015-04-01

    Full Text Available “The Socratic method” is a way of teaching philosophical thinking and knowledge by asking questions. 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

    2017-05-01

    As human experimentation continues to grow into an ever more complex and sophisticated endeavor, the relevant ethical and regulatory structures become more intricate. When pediatricians and general practitioners are invited by pharmaceutical companies to enroll their offices in a clinical trial or a multicenter observational study or when they develop their own research questions, they frequently find themselves at a loss in the human research environment. The legal and regulatory complexity may have an unintended deterring effect at a time when office-based high quality pediatric research is urgently needed to support evidence-based medicine. Unfortunately, in many instances, unaware practitioners become involved in low-risk research activities without knowing it and become entangled in legal, auditing, and compliance procedures. This paper, written in 2 parts, aims at providing a general guidance on the principles that regulate human research with a focus on pediatrics. Part 1 discusses the history, the legal framework, and the consent process and highlights some practical aspects of initial protocol submission, continued review, and institutional review board determinations with the main focus on multicenter clinical trials (industry-sponsored research). Part 2 focuses on pediatric research regulation, also known as subpart-D, and minimal risk research, which encompasses many research activities aimed at addressing questions that may emerge in pediatricians' practices (investigator-initiated research).

    Some of the questions raised are: 1. what types of presenting knowledge matter these days - and why? 2. for what type of communities (learning communities, communities focused on innovation) do they matter? What can be learned from the way science works within the rich spectrum of disciplines with respect to providing information: is the scientific method more debate-related or more focused on reproduction of experiments and how could OAI (dataproviders / services) play a role in these different approaches? 3. What is to be expected from different online collaborative – supposedly free - services and what general remarks can be made about their interoperability and functionality? 4. What are the quality assuring mechanisms in different communities and how can we translate these principles to further research or mere fruitful information exchange? I believe these are questions that should be raised to see also more clearly the impact of OAI. Within the Dutch context we have some experience with OAI via the D...

    Pregnancy is a time when expectant mothers may have numerous questions about their unborn children, especially when congenital anomalies are diagnosed prenatally. We sought to characterize information needs of pregnant women seen in the Vanderbilt Children's Hospital Fetal Center. Participants recorded questions from diagnosis through delivery. Questions were categorized by two researchers using a hierarchical taxonomy describing consumer health information needs. Consensus category assignments were made, and inter-rater reliability was measured with Cohen's Kappa. Sixteen participants reported 398 questions in 39 subcategories, of which the most common topics were prognosis (53 questions; 13.3%) and indications for intervention (31 questions; 7.8%). Inter-rater reliability of assignments showed moderate (κ=0.57) to substantial (κ=0.75) agreement for subcategories and primary categories, respectively. Pregnant women with prenatal diagnoses have diverse unmet information needs; a taxonomy of consumer health information needs may improve the ability to meet such needs through content and system design.

General national economy point of view: Judgment by politicians determines the possibilities of support by the government. 2. The business economy aspect: Here the most important matter is to construct the plants with dimensions permitting to obtain the highest profits possible. 3. The financing model: possible incentives must be taken into consideration as well as technical aspects, e.g. the service life of the plants.

    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

    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.

    2013-10-01

    Adequate information about physical activity habits is essential for surveillance, implementing, and evaluating public health initiatives in this area. Previous studies have shown that question order and differences in wording result in systematic differences in people's responses to questionnaires; however, this has never been shown for physical activity questions. The aim was to study the influence of different formulations and question order on self-report physical activity in a population-based health interview survey. Four samples of each 1000 adults were drawn at random from the National Person Register. A new question about physical activity was included with minor differences in formulations in samples 1-3. Furthermore, the question in sample 2 was included in sample 4 but was placed in the end of the questionnaire. The mean time spent on moderate physical activity varied between the four samples from 57 to 100 min/day. Question order was associated with the reported number of minutes spent on moderate-intensity physical activity and with prevalence of meeting the recommendation, whereas physical inactivity was associated with the differences in formulation of the question. Questionnaire context influences the way people respond to questions about physical activity significantly and should be tested systematically in validation studies of physical activity questionnaires. © 2012 John Wiley & Sons A/S.

    Wimmer, Eva; Rothweiler, Monika; Penke, Martina

    2017-05-01

    For children with sensorineural hearing loss the ability to understand wh-questions might be particularly challenging because they often have only restricted access to spoken language input during optimal periods of language acquisition. In previous research it has been suggested that this restricted input during critical stages in language acquisition might lead to syntactic deficits that persist into adolescence. In this study we want to pursue this issue by investigating the comprehension of wh-questions in German children with bilateral sensorineural hearing loss. We report results of a who-question comprehension task in a group of 21 3- to 4-year-old German hard-of-hearing children compared to a group of age-matched children with normal hearing. The group data and individual performance patterns suggest that the syntactic comprehension difficulties observed in some, but not all, of the children with hearing loss reflect a delay in the acquisition of who-question comprehension rather than a persistent syntactic deficit. Follow-up data elicited from a subgroup of children confirm this supposition. Copyright © 2017 Elsevier Inc. All rights reserved.

British Academy of Childhood Disability (BACD)-James Lind Alliance research priority setting partnership bringing together patients, carers and clinicians as equal stakeholders. UK health service and community. The BACD Strategic Research Group formed the partnership. A Steering Group was established; charity and professional partner organisations were recruited. Suggestions were gathered in an open survey and from research recommendations for statutory guidance. Items were aggregated to formulate indicative research questions and verified as uncertainties from research evidence. An interim survey was used to rank the questions to shortlist topics. A mixed group of stakeholders discussed the top 25 questions at the final priority setting workshop agreeing a final rank order and the top 10 research priorities. Partner organisations were 13 charities and 8 professional societies. 369 people submitted suggestions (40% non-clinicians). 76 people participated in the interim prioritisation (26 parents, 1 young person, 10 charity representatives, 39 clinicians); 22 took part in the final workshop (3 young people, 7 parents, 3 charity representatives, 9 professionals). The top three research priorities related to (1) establishing the optimal frequency and intensity (dose) for mainstream therapies, (2) means for selecting and encouraging use of communication strategies and (3) ways to improve children's attitudes towards disability. The top 10 included evaluating interventions to promote mobility, self-efficacy, mental health, continence, physical fitness, educational inclusion and reduce impacts of sleep disturbance. The methodology provided a systematic and transparent process to identify research priorities that included stakeholders that have

    2015-01-01

    Despite the wealth of mental-health information available online to consumers, research has shown that the mental-health information needs of consumers are not being met. This study contributes to that research by soliciting consumer questions directly, categorizing them, analyzing their form, and assessing the extent to which they can be answered from a trusted and vetted source of online information, namely the website of the US National Institute of Mental Health (NIMH). As an alternative to surveys and analyses of online activity, this study shows how consumer questions provide new insight into what consumers do not know and how they express their information needs. The study crowdsourced 100 consumer questions through Amazon Inc.’s Mechanical Turk. Categorization of the questions shows broad agreement with earlier studies in terms of the content of consumer questions. It also suggests that consumers’ grasp of mental health issues may be low compared to other health topics. The majority of the questions (74%) were simple in form, with the remainder being multi-part, multifaceted or narrative. Even simple-form questions could, however, have complex interpretations. Fifty four questions were submitted to the search box at the NIMH website. For 32 questions, no answer could be found in the top one to three documents returned. Inadequacies in the search and retrieval technology deployed at websites account for some of the failure to find answers. The nature of consumer questions in mental health also plays a role. A question that has a false presupposition is less likely to have an answer in trusted and vetted sources of information. Consumer questions are also expressed with a degree of specificity that makes the retrieval of relevant information difficult. The significance of this study is that it shows what an analysis of consumer mental-health questions can tell us about consumer information needs and it provides new insight into the difficulties facing

    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 electric and magnetic fields (EMF) produced by power lines and other electrical devices cause health effects. The purpose of this booklet is to answer some common questions that the Bonneville Power Administration (BPA) 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.

  13. Automatic Generation System of Multiple-Choice Cloze Questions and its Evaluation

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Since English expressions vary according to the genres, it is important for students to study questions that are generated from sentences of the target genre. Although various questions are prepared, it is still not enough to satisfy various genres which students want to learn. On the other hand, when producing English questions, sufficient grammatical knowledge and vocabulary are needed, so it is difficult for non-expert to prepare English questions by themselves. In this paper, we propose an automatic generation system of multiple-choice cloze questions from English texts. Empirical knowledge is necessary to produce appropriate questions, so machine learning is introduced to acquire knowledge from existing questions. To generate the questions from texts automatically, the system (1 extracts appropriate sentences for questions from texts based on Preference Learning, (2 estimates a blank part based on Conditional Random Field, and (3 generates distracters based on statistical patterns of existing questions. Experimental results show our method is workable for selecting appropriate sentences and blank part. Moreover, our method is appropriate to generate the available distracters, especially for the sentence that does not contain the proper noun.

    Quota sampling has been suggested as a potentially good method for Internet-based research and has been used by several researchers working with Internet samples. However, very little is known about the issues or concerns in using a quota sampling method in Internet research. The purpose of this article was to present the practical issues using quota sampling in an Internet-based study. During the Internet study, the research team recorded all recruitment issues that arose and made written notes indicating the possible reasons for the problems. In addition, biweekly team discussions were conducted for which written records were kept. Overall, quota sampling was effective in ensuring that an adequate number of midlife women were recruited from the targeted ethnic groups. However, during the study process, we encountered the following practical issues using quota sampling: (1) difficulty reaching out to women in lower socioeconomic classes, (2) difficulty ensuring authenticity of participants' identities, (3) participants giving inconsistent answers for the screening questions versus the Internet survey questions, (4) potential problems with a question on socioeconomic status, (5) resentment toward the research project and/or researchers because of rejection, and (6) a longer time and more expense than anticipated.

    For decades, the question of social selection vs social causation has been raised by public health researchers and social scientists to explain the association between socioeconomic factors and mood disorders.(1,2) The social selection or "downward drift" theory postulates that the disease itself limits an individual's educational and occupational achievements, leading to a lower socioeconomic status (SES). In contrast, the social causation hypothesis suggests that factors associated with low SES (e.g., stressful life events, poor health care access) increase the likelihood of disease onset or prolonged disease duration.(3,4) Simply stated, the end result of each hypothesis is as follows:

    2010-01-01

    Question answering (QA) has become one of the fastest growing topics in computational linguistics and information access. To advance research in the area of dialogue-based question answering, we propose a combination of methods from different scientific fields (i.e., Information Retrieval, Dialogue Systems, Semantic Web, and Machine Learning). This book sheds light on adaptable dialogue-based question answering. We demonstrate the technical and computational feasibility of the proposed ideas, the introspective methods in particular, by beginning with an extensive introduction to the dialogical

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

    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

    2016-12-14

    To identify the research priorities for medical nutrition education worldwide. A 5-step stakeholder engagement process based on methodological guidelines for identifying research priorities in health. 277 individuals were identified as representatives for 30 different stakeholder organisations across 86 countries. The stakeholder organisations represented the views of medical educators, medical students, doctors, patients and researchers in medical education. Each stakeholder representative was asked to provide up to three research questions that should be deemed as a priority for medical nutrition education. Research questions were critically appraised for answerability, sustainability, effectiveness, potential for translation and potential to impact on disease burden. A blinded scoring system was used to rank the appraised questions, with higher scores indicating higher priority (range of scores possible 36-108). 37 submissions were received, of which 25 were unique research questions. Submitted questions received a range of scores from 62 to 106 points. The highest scoring questions focused on (1) increasing the confidence of medical students and doctors in providing nutrition care to patients, (2) clarifying the essential nutrition skills doctors should acquire, (3) understanding the effectiveness of doctors at influencing dietary behaviours and (4) improving medical students' attitudes towards the importance of nutrition. These research questions can be used to ensure future projects in medical nutrition education directly align with the needs and preferences of research stakeholders. Funders should consider these priorities in their commissioning of research. Published by the BMJ Publishing Group Limited.

  1. 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.

  2. Electric Power Lines : Questions and Answers on Research into Health Effects.

    Energy Technology Data Exchange (ETDEWEB)

    United States. Bonneville Power Administration.

    1993-11-01

    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 electric and magnetic fields (EMF) produced by power lines and other electrical devices cause health effects. The purpose of this pamphlet is to answer some common questions that the Bonneville Power Administration (BPA) receives about the possible effects of power lines on health. (BPA is the Pacific Northwest`s Federal electric power marketing agency.) First, some basic electrical terms are defined, and electric and magnetic fields are described. Next, answers are given to several questions about recent scientific studies. We then describe how BPA is addressing public concerns raised by these studies. Some important information about electrical safety follows. The last section tells you how to obtain more detailed information about the health and safety issues summarized in this pamphlet.

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

    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.

  8. So much more than just a list: exploring the nature of critical questioning in undergraduate sciences

    Background: Critical thinking is one of the very highest orders of cognitive abilities and a key competency in higher education. Asking questions is an important component of rich learning experiences, structurally embedded in the operations of critical thinking. Our clear sense is that critical thinking and, within that, critical questioning, is heavily context dependent, in the sense that is applied, used by critical learners in a contextualised way. Purpose: Our research deals with enhancing science undergraduates' critical questioning. We are interested in understanding and describing the nature and development of students' critical questioning. The purpose is to conceptualise critical questioning as a competency, into three domains - knowledge, skills and attitudes/dispositions. We have no interest in a taxonomic category of context-free question-types called 'critical questions'. In contrast, our view is that 'being a critical questioner' trades heavily on context. Sources of evidence: Four cases are considered as illuminative of the dimensions of science undergraduates' critical questioning. Data were collected in natural learning environments through non-participant observation, audio-taping teacher-students interactions and semi-structured interviews. Students' written material resulting from diverse learning tasks was also collected. Main argument: Our supposition is that one vehicle for achieving university students as critical thinkers is to enable them not just to ask critical questions, but to be critical questioners. We relate critical questioning to three domains: (1) context, (2) competency and (3) delivery, and propose a model based on illuminating examples of the in-classroom action. Conclusions: The dimensions of the competency-context-delivery model provide a framework for describing successful student critical questioning, showing that students' capacity to be critical can be developed. It is possible, in our view, to generate critical

    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.

  12. The Auditory Comprehension of Wh-Questions in Aphasia: Support for the Intervener Hypothesis.

    Sheppard, Shannon M; Walenski, Matthew; Love, Tracy; Shapiro, Lewis P

    2015-06-01

    This study examines 3 hypotheses about the processing of wh-questions in both neurologically healthy adults and adults with Broca's aphasia. We used an eye tracking while listening method with 32 unimpaired participants (Experiment 1) and 8 participants with Broca's aphasia (Experiment 2). Accuracy, response time, and online gaze data were collected. In Experiment 1, we established a baseline for how unimpaired processing and comprehension of 4 types of wh-question (subject- and object-extracted who- and which-questions) manifest. There was no unambiguous support found for any of the 3 hypotheses in Experiment 1. In Experiment 2 with the Broca's participants, however, we found significantly lower accuracy, slower response times, and increased interference in our gaze data in the object-extracted which-questions relative to the other conditions. Our results provide support for the intervener hypothesis, which states that sentence constructions that contain an intervener (a lexical noun phrase) between a displaced noun phrase and its gap site result in a significant processing disadvantage relative to other constructions. We argue that this hypothesis offers a compelling explanation for the comprehension deficits seen in some participants with Broca's aphasia.

  13. A 2-1-1 research collaboration: participant accrual and service quality indicators.

    In times of crises, 2-1-1 serves as a lifeline in many ways. These crises often cause a spike in call volume that can challenge 2-1-1's ability to meet its service quality standards. For researchers gathering data through 2-1-1s, a sudden increase in call volume might reduce accrual as 2-1-1 has less time to administer study protocols. Research activities imbedded in 2-1-1 systems may affect directly 2-1-1 service quality indicators. Using data from a 2-1-1 research collaboration, this paper examines the impact of crises on call volume to 2-1-1, how call volume affects research participant accrual through 2-1-1, and how research recruitment efforts affect 2-1-1 service quality indicators. t-tests were used to examine the effect of call volume on research participant accrual. Linear and logistic regressions were used to examine the effect of research participant accrual on 2-1-1 service quality indicators. Data were collected June 2010-December 2011; data were analyzed in 2012. Findings from this collaboration suggest that crises causing spikes in call volume adversely affect 2-1-1 service quality indicators as well as accrual of research participants. Administering a brief (2-3 minute) health risk assessment did not affect service quality negatively, but administering a longer (15-18 minute) survey had a modest adverse effect on these indicators. In 2-1-1 research collaborations, both partners need to understand the dynamic relationship among call volume, research accrual, and service quality and adjust expectations accordingly. If research goals include administering a longer survey, increased staffing of 2-1-1 call centers may be needed to avoid compromising service quality.

    To identify and prioritize research questions of concern to the practice of pediatric critical care nursing practice. One-day consensus conference. By using a conceptual framework by Benner et al describing domains of practice in critical care nursing, nine international nurse researchers presented state-of-the-art lectures. Each identified knowledge gaps in their assigned practice domain and then poised three research questions to fill that gap. Then, meeting participants prioritized the proposed research questions using an interactive multivoting process. Seventh World Congress on Pediatric Intensive and Critical Care in Istanbul, Turkey. Pediatric critical care nurses and nurse scientists attending the open consensus meeting. Systematic review, gap analysis, and interactive multivoting. The participants prioritized 27 nursing research questions in nine content domains. The top four research questions were 1) identifying nursing interventions that directly impact the child and family's experience during the withdrawal of life support, 2) evaluating the long-term psychosocial impact of a child's critical illness on family outcomes, 3) articulating core nursing competencies that prevent unstable situations from deteriorating into crises, and 4) describing the level of nursing education and experience in pediatric critical care that has a protective effect on the mortality and morbidity of critically ill children. The consensus meeting was effective in organizing pediatric critical care nursing knowledge, identifying knowledge gaps and in prioritizing nursing research initiatives that could be used to advance nursing science across world regions.

  16. Robustness Analysis of Visual QA Models by Basic Questions

    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.

  18. From Question Answering to Visual Exploration

    McColgin, Dave W.; Gregory, Michelle L.; Hetzler, Elizabeth G.; Turner, Alan E.

    2006-08-11

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

    2006-01-01

    PURPOSE Addressing important but complex research questions often necessitates the creation of innovative mixed methods designs. This report describes an approach to developing research designs for studying important but methodologically challenging research questions. METHODS The Methodological Think Tank has been held annually in conjunction with the Primary Care Research Methods and Statistics Conference in San Antonio since 1994. A group of 3 to 4 methodologists with expertise balanced between quantitative and qualitative backgrounds is invited by the think tank coordinators to serve on a 2-day think tank to discuss a research question selected from those submitted in response to a call for proposals. During the first half-day, these experts explore the content area with the investigator, often challenging beliefs and assumptions. During the second half-day, the think tank participants systematically prune potential approaches until a desirable research method is identified. RESULTS To date, the most recent 7 think tanks have produced fundable research designs, with 1 being funded by a K award and 4 by R01 grants. All participating investigators attributed much of their success to think tank participation. Lessons learned include (1) the importance of careful selection of participating methodologists, (2) all think tank communities of inquiry must go through 4 stages of development from pseudocommunity to community, and (3) the critical importance of listening by the investigator. CONCLUSION Researchers and academic departments could use this process locally to develop innovative research designs. PMID:17003146

    Stars account for only about 0.5% of the content of the Universe; the bulk of the Universe is optically dark. The dark side of the Universe is comprised of: at least 0.1% light neutrinos; 3.5% ± 1% baryons; 29% ± 4% cold dark matter; and 66% ± 6% dark energy. Now that we have characterized the dark side of the Universe, the challenge is to understand it. The critical questions are: (1) What form do the dark baryons take? (2) What is (are) the constituent(s) of the cold dark matter? (3) What is the nature of the mysterious dark energy that is causing the Universe to speed up

    In Nigeria the current prevalence of HIV is 4.1% with over 3.5 million infected and estimated 1.5 million in need of anti-retroviral treatment. Epidemiological and implementation studies are necessary for monitoring and evaluation of interventions. To define research areas which can be addressed by participants of the Nigeria Field Epidemiology and Training Programme (NFELTP) a workshop was held in April 2013 in Abuja, Nigeria. Priority research areas were identified using criteria lists for ranking of the relevance of research questions. Based on a research matrix, NFELTP residents developed the aims and objectives, study design for HIV-related research proposals. This workshop was the first workshop held by the NFELTP to establish an inventory of research questions which can be addressed by the residents within their training period. This inventory will help to increase HIV/AIDS-related activities of NFELTP which are in accordance with research needs in Nigeria and PEPFAR objectives. PMID:25426209

  8. Semi-automated categorization of open-ended questions

    2016-08-01

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

    Self-management is crucial to diabetes care and providing expert-vetted content for answering patients' questions is crucial in facilitating patient self-management. The aim is to investigate the use of information retrieval techniques in recommending patient education materials for diabetic questions of patients. We compared two retrieval algorithms, one based on Latent Dirichlet Allocation topic modeling (topic modeling-based model) and one based on semantic group (semantic group-based model), with the baseline retrieval models, vector space model (VSM), in recommending diabetic patient education materials to diabetic questions posted on the TuDiabetes forum. The evaluation was based on a gold standard dataset consisting of 50 randomly selected diabetic questions where the relevancy of diabetic education materials to the questions was manually assigned by two experts. The performance was assessed using precision of top-ranked documents. We retrieved 7510 diabetic questions on the forum and 144 diabetic patient educational materials from the patient education database at Mayo Clinic. The mapping rate of words in each corpus mapped to the Unified Medical Language System (UMLS) was significantly different (Pretrieval algorithms. For example, for the top-retrieved document, the precision of the topic modeling-based, semantic group-based, and VSM models was 67.0%, 62.8%, and 54.3%, respectively. This study demonstrated that topic modeling can mitigate the vocabulary difference and it achieved the best performance in recommending education materials for answering patients' questions. One direction for future work is to assess the generalizability of our findings and to extend our study to other disease areas, other patient education material resources, and online forums. ©Yuqun Zeng, Xusheng Liu, Yanshan Wang, Feichen Shen, Sijia Liu, Majid Rastegar Mojarad, Liwei Wang, Hongfang Liu.

  13. Psychotherapy Outcome Research: Issues and Questions.

    Science.gov (United States)

    Shean, Glenn

    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.

  14. Osteoblast-like MC3T3-E1 Cells Prefer Glycolysis for ATP Production but Adipocyte-like 3T3-L1 Cells Prefer Oxidative Phosphorylation.

    Mesenchymal stromal cells (MSCs) are early progenitors that can differentiate into osteoblasts, chondrocytes, and adipocytes. We hypothesized that osteoblasts and adipocytes utilize distinct bioenergetic pathways during MSC differentiation. To test this hypothesis, we compared the bioenergetic profiles of preosteoblast MC3T3-E1 cells and calvarial osteoblasts with preadipocyte 3T3L1 cells, before and after differentiation. Differentiated MC3T3-E1 osteoblasts met adenosine triphosphate (ATP) demand mainly by glycolysis with minimal reserve glycolytic capacity, whereas nondifferentiated cells generated ATP through oxidative phosphorylation. A marked Crabtree effect (acute suppression of respiration by addition of glucose, observed in both MC3T3-E1 and calvarial osteoblasts) and smaller mitochondrial membrane potential in the differentiated osteoblasts, particularly those incubated at high glucose concentrations, indicated a suppression of oxidative phosphorylation compared with nondifferentiated osteoblasts. In contrast, both nondifferentiated and differentiated 3T3-L1 adipocytes met ATP demand primarily by oxidative phosphorylation despite a large unused reserve glycolytic capacity. In sum, we show that nondifferentiated precursor cells prefer to use oxidative phosphorylation to generate ATP; when they differentiate to osteoblasts, they gain a strong preference for glycolytic ATP generation, but when they differentiate to adipocytes, they retain the strong preference for oxidative phosphorylation. Unique metabolic programming in mesenchymal progenitor cells may influence cell fate and ultimately determine the degree of bone formation and/or the development of marrow adiposity. © 2018 American Society for Bone and Mineral Research. © 2018 American Society for Bone and Mineral Research.

    Hanson-Abromeit, Deanna; Sena Moore, Kimberly

    2014-01-01

    Music therapists are challenged to present evidence on the efficacy of music therapy treatment and incorporate the best available research evidence to make informed healthcare and treatment decisions. Higher standards of evidence can come from a variety of sources including systematic reviews. To define and describe a range of research review methods using examples from music therapy and related literature, with emphasis on the systematic review. In addition, the authors provide a detailed overview of methodological processes for conducting and reporting systematic reviews in music therapy. The systematic review process is described in five steps. Step 1 identifies the research plan and operationalized research question(s). Step 2 illustrates the identification and organization of the existing literature related to the question(s). Step 3 details coding of data extracted from the literature. Step 4 explains the synthesis of coded findings and analysis to answer the research question(s). Step 5 describes the strength of evidence evaluation and results presentation for practice recommendations. Music therapists are encouraged to develop and conduct systematic reviews. This methodology contributes to review outcome credibility and can determine how information is interpreted and used by clinicians, clients or patients, and policy makers. A systematic review is a methodologically rigorous research method used to organize and evaluate extant literature related to a clinical problem. Systematic reviews can assist music therapists in managing the ever-increasing literature, making well-informed evidence based practice and research decisions, and translating existing music-based and nonmusic based literature to clinical practice and research development. © the American Music Therapy Association 2014.

    Parrott and Koralus argue that a particular cognitive factor--"impaired endogenous question raising"--offers a parsimonious account of three delusion-related phenomena: (1) the development of the Capgras delusion; (2) evidence that patients with schizophrenia outperform healthy control participants on a conditional reasoning task; and (3) evidence that deluded individuals "jump to conclusions". In this response, I assess these claims, and raise my own questions about the "erotetic" theory of delusional thinking.

  6. Impacts of Socratic questioning on moral reasoning of nursing students.

    2018-03-01

    Nurses are often faced with complex situations that made them to make ethical decisions; and to make such decisions, they need to possess the power of moral reasoning. Studies in Iran show that the majority of nursing students lack proper ethical development. Socratic teaching is a student-centered method which is strongly opposed to the lecturing method. This study was conducted to evaluate the impacts of Socratic questioning on the moral reasoning of the nursing students. In a quasi-experimental study, Crisham's Nursing Dilemma Test was used to evaluate the results of three groups before, immediately after, and 2 months after intervention. The data were analyzed using the SPSS statistical software (v 15). Participants and research context: Through random allocation, 103 nursing students were divided into three groups. In experiment group 1 (37 students), intervention consisted of Socratic questioning-based sessions on ethics and how to deal with moral dilemmas; experiment group 2 (33 students) attended a 4-h workshop; and the control group (33 students) was not subject to any interventions. Signed informed consent forms: This research was approved by the Ethics Committee of the University. All the participants signed written informed consents. There were significant differences between experiment group 1 and experiment group 2's pre-test and post-test scores on moral reasoning (p ≤ 0.001, p ≤ 0.001), nursing principled thinking (p ≤ 0.001, p ≤ 0.001), and practical considerations (p ≤ 0.001, p ≤ 0.031). Both the teaching approaches improved the subjects' moral reasoning; however, Socratic questioning proved more effective than lecturing. Compared to other similar studies in Iran and other countries, the students had inadequate moral reasoning competence. This study confirms the need for the development of an efficient course on ethics in the nursing curriculum. Also, it appears that Socratic questioning is an effective method to teach nursing ethics

    2015-04-01

    LiNi1/3Co1/3Mn1/3O2 (NCM) is a promising cathode material for lithium-ion battery. In this research, a facile co-precipitation process is employed, during which the mixed solution of NH3·H2O, H2O2 (30% aqueous solution) and LiOH·H2O is added into the nitrate solution. Notably, H2O2 is introduced as the oxidant and dispersant during the co-precipitation process to oxidize the metal ions and decrease the agglomeration of the precursor by giving out O2, and then improves the specific capacity, stability and energy density of NCM. Additionally, O3 is employed to further oxidize NCM to enhance the stability during the calcination process. The obtained NCM material with single crystal structure exhibits a high initial discharge specific capacity of 208.9 mAh g-1 at 0.1 C (1 C = 280 mA g-1), an excellent cycle stability with high retained capacity of 176.3 mAh g-1 after 50 cycles, and a high initial discharge specific capacities of 150.6 mAh g-1 at 5 C even at a high cutoff potential (4.6 V).

    While randomized controlled trials (RCTs) are the gold standard for research, many research questions cannot be ethically and practically answered using an RCT. Comparative effectiveness research (CER) techniques are often better suited than RCTs to address the effects of an intervention under routine care conditions, an outcome otherwise known as effectiveness. CER research techniques covered in this section include: effectiveness-oriented experimental studies such as pragmatic trials and cluster randomized trials, treatment response heterogeneity, observational and database studies including adjustment techniques such as sensitivity analysis and propensity score analysis, systematic reviews and meta-analysis, decision analysis, and cost effectiveness analysis. Each section describes the technique and covers the strengths and weaknesses of the approach.

    Geometry, a branch of mathematics, has an important role in mathematics learning. This research aims to find out the effect of learning model, emotional intelligence, and the interaction between learning model and emotional intelligence toward students’ mathematics achievement. This research is quasi-experimental research with 2 × 3 factorial design. The sample in this research included 179 Senior High School students on 11th grade in Sukoharjo Regency, Central Java, Indonesia in academic year of 2016/2017. The sample was taken by using stratified cluster random sampling. The results showed that: the student are taught by Thinking Aloud Pairs Problem-Solving using HOTs questions provides better mathematics learning achievement than Make A Match using HOTs questions. High emotional intelligence students have better mathematics learning achievement than moderate and low emotional intelligence students, and moderate emotional intelligence students have better mathematics learning achievement than low emotional intelligence students. There is an interaction between learning model and emotional intelligence, and these affect mathematics learning achievement. We conclude that appropriate learning model can support learning activities become more meaningful and facilitate students to understand material. For further research, we suggest to explore the contribution of other aspects in cooperative learning modification to mathematics achievement.

    Full Text Available Questioning is a useful and relevant tool to facilitate classroom discussion in a literature class. This study identified the levels of questions teachers use in their literature class, determined the different question strategies they utilized and proposed activities to enhance the questioning strategies of literature teachers. Video analysis was the main instrument used. These videos were provided during the conduct of class observations by the researchers. There were eight respondents in the study selected through total enumeration. They are teachers from Gubat Cluster of secondary schools of Sorsogon Province. To identify the levels of questions and questioning strategies, question tally form and percentage were used. Results revealed that knowledge was the most used level of questions followed by comprehension, application, analysis, synthesis and evaluation. The most used question technique is the participation, followed by proving, sequencing, wait time, balance and student questions. It was recommended that literature teachers vary their level of questions when discussing literary pieces. They may utilize different question techniques to develop critical thinking skills of their students. The use of the proposed activities may enhance the questioning strategies of literature teachers. Likewise, school heads and program supervisors may utilize video analysis technique as a mode for classroom observation.

    Within particle physics itself, Gauguin's questions may be interpreted as: P1 - What is the status of the Standard Model? P2 - What physics may lie beyond the Standard Model? P3 - What is the 'Theory of Everything'? Gauguin's questions may also asked within a cosmological context: C1 - What were the early stages of the Big Bang? C2 - What is the material content of the Universe today? C3 - What is the future of the Universe? In this talk I preview many of the topics to be discussed in the plenary sessions of this conference, highlighting how they bear on these fundamental questions

    1995-08-01

    In recent years significant studies have been initiated on the feasibility of utilizing a portion of the 3km S-band accelerator at SLAC to drive a short wavelength (4.5-1.5 A) Linac Coherent Light Source (LCLS), a Free Electron Laser (FEL) operating in the Self- Amplified Spontaneous Emission (SASE) regime. Electron beam requirements for single-pass saturation in a minimal time include: (1) a peak current in the 7 kA range, (2) a relative energy spread of <0.05%, and (3) a transverse emittance, ε[r-m], approximating the diffraction limit condition ε = λ / 4π, where lambda(m) is the output wavelength. Requirements on the insertion device include field error levels of 0.02% for keeping the electron bunch centered on and in phase with the amplified photons, and a focusing beta of 8 m/rad for inhibiting the dilution of its transverse density. Although much progress has been made in developing individual components and beam processing techniques necessary for LCLS operation down to approx. 20 A, a substantial amount of research and development is still required in a number of theoretical and experimental areas leading to the construction and operation of a 4.5-1.5 A LCLS. In this paper we report on a research and development program underway and in planning at SLAC for addressing critical questions in these areas

    Full Text Available In light of current research gaps in online student-generated questions (SGQ (as most studies on the content types, forms, and performance criteria of SGQ are done in math, adopting a structured format, using a paper-and-pencil form, and paying less attention to affective aspects, the purposes of this study are: first, to analyze the content, forms, and techniques of online SGQ via content analysis; second, to develop the creative indicators for online SGQ and establish the validity of the devised indicators. For the first purpose, 792 questions generated by 54 student teachers during online SGQ activities were subjected to content analysis. For the second purpose, another group of 40 student teachers completed a consensus questionnaire, and the data were analyzed via repeated measures, followed by post-hoc comparisons. Four major findings were obtained: 1 with regard to the contents of online SGQ, connections to personal daily life and future personal goals were frequently observed; 2 most participants took advantage of the formatting, color, and graphics features afforded in computer technologies during online SGQ to suit multiple purposes; 3 participants exhibited versatile skills during SGQ; 4 questions with different levels of creativity differed significantly in terms of novelty and interestingness indicators, supporting the validity of the devised indicators. Yet, no significant differences were found in the usefulness indicator, supporting the claim that novelty and interestingness do not necessarily compromise the perceived usefulness of the generated item. Based on the findings, suggestions for SGQ, creative teaching, and future research are provided.

    Visual Question Answering (VQA) is one of the most popular research fields in machine learning which aims to let the computer learn to answer natural language questions with images. In this paper, we propose a new method called hierarchical dynamic memory networks (HDMN), which takes both question attention and visual attention into consideration impressed by Co-Attention method, which is the best (or among the best) algorithm for now. Additionally, we use bi-directional LSTMs, which have a better capability to remain more information from the question and image, to replace the old unit so that we can capture information from both past and future sentences to be used. Then we rebuild the hierarchical architecture for not only question attention but also visual attention. What's more, we accelerate the algorithm via a new technic called Batch Normalization which helps the network converge more quickly than other algorithms. The experimental result shows that our model improves the state of the art on the large COCO-QA dataset, compared with other methods.

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

    Relaxor lead magnesium niobate (PMN)-based materials exhibit complex structures and unusual properties that have been puzzling researchers for decades. In this paper, a new ternary solid solution of Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 -Bi(Zn 2/3 Nb 1/3 )O 3 (PMN-PT-BZN) is prepared in the form of ceramics, and the effects of the incorporation of BZN into the PMN-PT binary system are investigated. The crystal structure favors a pseudocubic symmetry and the relaxor properties are enhanced as the concentration of BZN increases. The relaxor behavior and the related phase transformations are studied by dielectric spectroscopy. A phase diagram mapping out the characteristic temperatures and various states is established. Interestingly, the piezoelectricity of the PMN-PT ceramics is significantly enhanced by the BZN substitution, with an optimal value of d 33 reaching 826 pC/N for 0.96[0.7Pb(Mg 1/3 Nb 2/3 )O 3 -0.3PbTiO 3 ]-0.04Bi(Zn 2/3 Nb 1/3 )O 3 . This paper provides a better understanding of the relaxor ferroelectric behavior, and unveils a new relaxor-based ternary system as piezoelectric materials potentially useful for electromechanical transducer applications.

    Full Text Available Abstract Background Intimate partner violence (IPV including physical, sexual and emotional violence, causes short and long term ill-health. Brief questions that reliably identify women experiencing IPV who present in clinical settings are a pre-requisite for an appropriate response from health services to this substantial public health problem. We estimated the sensitivity and specificity of four questions (HARK developed from the Abuse Assessment screen, compared to a 30-item abuse questionnaire, the Composite Abuse Scale (CAS. Methods We administered the four HARK questions and the CAS to women approached by two researchers in general practice waiting rooms in Newham, east London. Inclusions: women aged more than 17 years waiting to see a doctor or nurse, who had been in an intimate relationship in the last year. Exclusions: women who were accompanied by children over four years of age or another adult, too unwell to complete the questionnaires, unable to understand English or unable to give informed consent. Results Two hundred and thirty two women were recruited. The response rate was 54%. The prevalence of current intimate partner violence, within the last 12 months, using the CAS cut off score of ≥3, was 23% (95% C.I. 17% to 28% with pre-test odds of 0.3 (95% C.I. 0.2 to 0.4. The receiver operator characteristic curve demonstrated that a HARK cut off score of ≥1 maximises the true positives whilst minimising the false positives. The sensitivity of the optimal HARK cut-off score of ≥1 was 81% (95% C.I. 69% to 90%, specificity 95% (95% C.I. 91% to 98%, positive predictive value 83% (95% C.I. 70% to 91%, negative predictive value 94% (95% C.I. 90% to 97%, likelihood ratio 16 (95% C.I. 8 to 31 and post-test odds 5. Conclusion The four HARK questions accurately identify women experiencing IPV in the past year and may help women disclose abuse in general practice. The HARK questions could be incorporated into the electronic medical record

    The ocean provides food, economic activity, and cultural value for a large proportion of humanity. Our knowledge of marine ecosystems lags behind that of terrestrial ecosystems, limiting effective protection of marine resources. We describe the outcome of 2 workshops in 2011 and 2012 to establish a list of important questions, which, if answered, would substantially improve our ability to conserve and manage the world's marine resources. Participants included individuals from academia, government, and nongovernment organizations with broad experience across disciplines, marine ecosystems, and countries that vary in levels of development. Contributors from the fields of science, conservation, industry, and government submitted questions to our workshops, which we distilled into a list of priority research questions. Through this process, we identified 71 key questions. We grouped these into 8 subject categories, each pertaining to a broad component of marine conservation: fisheries, climate change, other anthropogenic threats, ecosystems, marine citizenship, policy, societal and cultural considerations, and scientific enterprise. Our questions address many issues that are specific to marine conservation, and will serve as a road map to funders and researchers to develop programs that can greatly benefit marine conservation. © 2014 The Authors.

  20. Protein Electrochemistry: Questions and Answers.

    Science.gov (United States)

    Fourmond, V; Léger, C

    This chapter presents the fundamentals of electrochemistry in the context of protein electrochemistry. We discuss redox proteins and enzymes that are not photoactive. Of course, the principles described herein also apply to photobioelectrochemistry, as discussed in later chapters of this book. Depending on which experiment is considered, electron transfer between proteins and electrodes can be either direct or mediated, and achieved in a variety of configurations: with the protein and/or the mediator free to diffuse in solution, immobilized in a thick, hydrated film, or adsorbed as a sub-monolayer on the electrode. The experiments can be performed with the goal to study the protein or to use it. Here emphasis is on mechanistic studies, which are easier in the configuration where the protein is adsorbed and electron transfer is direct, but we also explain the interpretation of signals obtained when diffusion processes affect the response.This chapter is organized as a series of responses to questions. Questions 1-5 are related to the basics of electrochemistry: what does "potential" or "current" mean, what does an electrochemical set-up look like? Questions 6-9 are related to the distinction between adsorbed and diffusive redox species. The answers to questions 10-13 explain the interpretation of slow and fast scan voltammetry with redox proteins. Questions 14-19 deal with catalytic electrochemistry, when the protein studied is actually an enzyme. Questions 20, 21 and 22 are general.

  1. Divorce or Continue Marriage for Child? An Important Question about Psychological Adjustment of Child

    Directory of Open Access Journals (Sweden)

    Nilgun Ongider Gregory

    Full Text Available This study focused on finding answers about an important question that parents are recently asking psychological professionals. This question has become more relevant in the last couple of decades as there are increasing divorce rates in Turkey and the rest of the world. Because of this reason, parents are asking the important question: is it better for our child to divorce or continue our marriage? Researchers come up with very different results to this question. They need to not only focus on the effects of divorce itself but also need to examine the quality of the relationship between the parents. Parents need to remember this very important point that divorce is not the only thing that effects children's psychological adjustment by itself. So, the answer of the question to divorce or stay together is answered by the amount of parental conflict and the quality of the parent's relationship. As a result, the ideal environment for children's psychological development is living with both parents in the same household and having a low-conflict parents.

    2016-12-01

    Full Text Available In an interrogative sentence in Mandarin language, a question word can be placed in the beginning, middle or end of a sentence. Because of the different nation and culture, when a foreign student learns Mandarin, they find it difficult to understand the question words and the position of the question words in that language. Because of that, the writer proposes to explain such problems. This research aims to find out what are the types of question words in Mandarin, and also to explain the function and usage of question words in the Mandarin interrogative sentence. An interrogative sentence is a very important sentence.

    To solicit expert opinions and develop consensus around the research that is needed to improve cancer rehabilitation for older adults. Delphi methods provided a structured process to elicit and prioritize research questions from national experts. National, Web-based survey. Members (N=32) of the American Congress of Rehabilitation Medicine completed at least 1 of 3 investigator-developed surveys. Not applicable. In the first survey, participants identified up to 5 research questions that needed to be answered to improve cancer rehabilitation for older adults. In 2 subsequent surveys, participants viewed the compilation of questions, rated the importance of each question, and identified the 5 most important questions. This generated priority scores for each question. Consensus scores were created to describe the degree of agreement around the priority of each question. Highest priority research concerns the epidemiology and measurement of function and disability in older adult cancer survivors; the effects of cancer rehabilitation interventions on falls, disability, participation, survival, costs, quality of care, and health care utilization; and testing models of care that facilitate referrals from oncology to rehabilitation providers as part of coordinated, multicomponent care. A multipronged approach is needed to fill these gaps, including targeted funding opportunities developed with an advisory panel of cancer rehabilitation experts, development of a research network to facilitate novel collaborations and grant proposals, and coordinated efforts of clinical groups to advocate for funding, practice change, and policy change.

    Limited health literacy (HL) contributes to poor health outcomes and disparities, and direct measurement is often time-intensive. Self-reported HL questions have not been validated among Spanish-speaking and diverse English-speaking populations. To evaluate three self-reported questions: 1 "How confident are you filling out medical forms?"; 2 "How often do you have problems learning about your medical condition because of difficulty understanding written information?"; and 3 "How often do you have someone help you read hospital materials?" Answers were based on a 5-point Likert scale. This was a validation study nested within a trial of diabetes self-management support in the San Francisco Department of Public Health. English and Spanish-speaking adults with type 2 diabetes receiving primary care. Using the Test of Functional Health Literacy in Adults (s-TOFHLA) in English and Spanish as the reference, we classified HL as inadequate, marginal, or adequate. We calculated the C-index and test characteristics of the three questions and summative scale compared to the s-TOFHLA and assessed variations in performance by language, race/ethnicity, age, and education. Of 296 participants, 48% were Spanish-speaking; 9% were White, non-Hispanic; 47% had inadequate HL and 12% had marginal HL. Overall, 57% reported being confident with forms "somewhat" or less. The "confident with forms" question performed best for detecting inadequate (C-index = 0.82, (0.77-0.87)) and inadequate plus marginal HL (C index = 0.81, (0.76-0.86); pSpanish and English speakers with adequate HL and those with inadequate and/or inadequate plus marginal HL. The "confident with forms" question or the summative scale may be useful for estimating HL in clinical research involving Spanish-speaking and English-speaking, chronically-ill, diverse populations.

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

    Full Text Available Abstract Background Despite the increasing mobilization of researchers and funding organizations around knowledge translation (KT in Canada and elsewhere, many questions have been only partially answered, particularly in the field of population health. This article presents the results of a systematic process to draw out possible avenues of collaboration for researchers, practitioners and decision-makers who work in the area of KT. The main objective was to establish a research agenda on knowledge translation in population health. Methods Using the Concept Mapping approach, the research team wanted to identify priority themes for the development of research on KT in population health. Mapping is based on multivariate statistical analyses (multidimensional scaling and hierarchical cluster analysis in which statements produced during a brainstorming session are grouped in weighted clusters. The final maps are a visual representation of the priority themes of research on KT. Especially designed for facilitating consensus in the understanding and organization of various concepts, the Concept Mapping method proved suitable for achieving this objective. Results The maps were produced by 19 participants from university settings, and from institutions within the health and social services network. Three main perspectives emerge from this operation: (1 The evaluation of the effectiveness of KT efforts is one of the main research priorities; (2 The importance of taking into consideration user contexts in any KT effort; (3 The challenges related to sharing power for decision-making and action-taking among various stakeholder groups. These perspectives open up avenues of collaboration for stakeholders who are involved in research on KT. Besides these three main perspectives, the concept maps reveal three other trends which should be emphasized. Conclusion The Concept Mapping process reported in this article aimed to provoke collective reflection on the

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

  12. Can workers answer their questions about occupational safety and health: challenges and solutions.

    Science.gov (United States)

    Rhebergen, Martijn; Van Dijk, Frank; Hulshof, Carel

    2012-01-01

    Many workers have questions about occupational safety and health (OSH). Answers to these questions empower them to further improve their knowledge about OSH, make good decisions about OSH matters and improve OSH practice when necessary. Nevertheless, many workers fail to find the answers to their questions. This paper explores the challenges workers may face when seeking answers to their OSH questions. Findings suggest that many workers may lack the skills, experience or motivation to formulate an answerable question, seek and find information, appraise information, compose correct answers and apply information in OSH practice. Simultaneously, OSH knowledge infrastructures often insufficiently support workers in answering their OSH questions. This paper discusses several potentially attractive strategies for developing and improving OSH knowledge infrastructures: 1) providing courses that teach workers to ask answerable questions and to train them to find, appraise and apply information, 2) developing information and communication technology tools or facilities that support workers as they complete one or more stages in the process from question to answer and 3) tailoring information and implementation strategies to the workers' needs and context to ensure that the information can be applied to OSH practice more easily.

    Patient-centered research requires the meaningful involvement of patients and caregivers throughout the research process. The objective of this study was to create a process for sustainable engagement for research prioritization within oncology. From December 2014 to 2016, a network of engaged patients for research prioritization was created in partnership with the Bladder Cancer Advocacy Network (BCAN): the BCAN Patient Survey Network (PSN). The PSN leveraged an online bladder cancer community with additional recruitment through print advertisements and social media campaigns. Prioritized research questions were developed through a modified Delphi process and were iterated through multidisciplinary working groups and a repeat survey. In year 1 of the PSN, 354 patients and caregivers responded to the research prioritization survey; the number of responses increased to 1034 in year 2. The majority of respondents had non-muscle-invasive bladder cancer (NMIBC), and the mean time since diagnosis was 5 years. Stakeholder-identified questions for noninvasive, invasive, and metastatic disease were prioritized by the PSN. Free-text questions were sorted with thematic mapping. Several questions submitted by respondents were among the prioritized research questions. A final prioritized list of research questions was disseminated to various funding agencies, and a highly ranked NMIBC research question was included as a priority area in the 2017 Patient-Centered Outcomes Research Institute announcement of pragmatic trial funding. Patient engagement is needed to identify high-priority research questions in oncology. The BCAN PSN provides a successful example of an engagement infrastructure for annual research prioritization in bladder cancer. The creation of an engagement network sets the groundwork for additional phases of engagement, including design, conduct, and dissemination.

  14. 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.

    2014-01-01

    Full Text Available This paper presents new preparation method of Pt/SnO2, an important catalytic system. Besides of its application as a heterogenic industrial catalyst, it is also used as a catalyst in electrochemical processes, especially in fuel cells. Platinum is commonly used as an anode catalyst in low temperature fuel cells, fuelled with alcohols of low molecular weight such as methanol. Platinum(0-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex was used as a precursor of metallic phase. The aim of the research was to obtain a highly active in electrochemical system Pt/SnO2 catalyst with low metal load. Considering small size of Pt crystallites, it should result in high activity of Pt/SnO2 system. The presented method of SnO2 synthesis allows for obtaining support consisting of nanoparticles. The effect of the thermal treatment on activity of Pt/SnO2 gel was demonstrated. The system properties were investigated using TEM, FTIR (ATR, and XRD techniques to describe its thermal structural evolution. The results showed two electrocatalytical activity peaks for drying at a temperature of 430 K and above 650 K.

    2017-04-01

    Full Text Available When the literature for measurement and evaluation in education is reviewed, research related to student achievement are mainly outcome-oriented rather than process-oriented. Researchers pay attention to the responses that a student constructs or chooses, and ignore the cognitive processes that forces students to construct or choose that specific response. Recognizing the cognitive processes a student uses in responding to a question affects the item construction process and psychometric audit on items. Response behavior is a result of a cognitive process used to respond to a question and is accepted as an indicator of student cognitive competence. This study aims to determine the students’ response behaviors for open-ended questions. The study group consisted of 70 students from the 5th grade studying during the 2015-2016 education year spring term in the Cankaya and Mamak districts of Ankara province, Turkey. An authentic achievement test which consisted of eight open-ended questions is used as the data collection tool. Students are asked to write in detail how they construct their response in their mind in the blank space set aside after each question. Data is analyzed via grouping students’ response behaviors and expert opinions. Research findings revealed that students perform 14 different response behaviors for open-ended questions. These behaviors are themed as responses constructed directly from the text, responses constructed by interpreting the text, and responses constructed by linking real life and the text.

    The research sought to determine (1) how use of the PubMed free full-text (FFT) limit affects citation retrieval and (2) how use of the FFT limit impacts the types of articles and levels of evidence retrieved. Four clinical questions based on a research agenda for physical therapy were searched in PubMed both with and without the use of the FFT limit. Retrieved citations were examined for relevancy to each question. Abstracts of relevant citations were reviewed to determine the types of articles and levels of evidence. Descriptive analysis was used to compare the total number of citations, number of relevant citations, types of articles, and levels of evidence both with and without the use of the FFT limit. Across all 4 questions, the FFT limit reduced the number of citations to 11.1% of the total number of citations retrieved without the FFT limit. Additionally, high-quality evidence such as systematic reviews and randomized controlled trials were missed when the FFT limit was used. Health sciences librarians play a key role in educating users about the potential impact the FFT limit has on the number of citations, types of articles, and levels of evidence retrieved.

    2017-10-01

    This study examines how group members' questions shape member participation in health counselling and health education groups. The study applies conversation analytic principles as a method. The data consist of video-recorded health education lessons in secondary school and health counselling sessions for adults with a high risk of Type 2 diabetes. Group members' questions accomplish a temporary change in participatory roles. They are used to 1) request counselling, 2) do counselling or 3) challenge previous talk. They are usually treated as relevant and legitimate actions by the participants, but are occasionally interpreted as transitions outside the current action or topic. Group members' questions result in a shift from leader-driven to member-driven discussion. Thus they constitute a pivot point for detecting changes in participation in group interventions. Observing the occurrence of group members' questions helps group leaders to adjust their own actions accordingly and thus facilitate or guide group participation. Comparison of the type and frequency of members' questions is a way to detect different trajectories for delivering group interventions and can thus be used to develop methods for process evaluation of interventions.

    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.

    Foxp3, which encodes the transcription factor scurfin, is indispensable for the development and function of CD4 + CD25 + regulatory T cells (Treg). Recent data suggest conversion of peripheral CD4 + CD25 - naive T cells to CD4 + CD25 + Treg by acquisition of Foxp3 through costimulation with TCR and TGF-β or forced expression of the gene. One critical question is how Foxp3 causes T cells to become regulatory. In the present work, we demonstrate that Foxp3 can induce heme oxygenase-1 (HO-1) expression and subsequently such regulatory phenotypes as the suppression of nontransfected cells in a cell-cell contact-dependent manner as well as impaired proliferation and production of cytokines upon stimulation in Jurkat T cells. Moreover, we confirm the expression of both Foxp3 and HO-1 in peripheral CD4 + CD25 + Treg and suppressive function of the cells are relieved by the inhibition of HO-1 activity. In summary, we demonstrate that Foxp3 induces HO-1 expression and HO-1 engages in Foxp3-mediated immune suppression

    The inclusion of able-bodied athletes within disability sport, a phenomenon known as reverse integration, has sparked significant debate within adapted physical activity. Although researchers and practitioners have taken up positions for or against reverse integration, there is a lack of supporting research on the experiences of athletes who already play in such settings. In this study, we explore how competitive female athletes who have a disability experience reverse integration in Canadian wheelchair basketball. Athletic identity was used as the initial conceptual framework to guide semistructured interviews with nine participants. The results suggest that participation in this context contributed to positive athletic identities. Interviews also pointed to the unexpected theme of "what's the difference?" that this sporting context provided a space for the questioning and creative negotiation of the categories of disability and able-bodiedness. Methodologically, this paper also explores the possibilities and challenges of inter- worldview and insider-outsider research collaboration.

    1992-05-01

    This workshop was designed to bring together a group of scholars, primarily from the social sciences, to explore research that might help in dealing with global climate change. To illustrate the state of present understanding, it seemed useful to focus this workshop on three broad questions that are involved in coping with climate change. These are: (1) How can the anticipated economic costs and benefits of climate change be identified; (2) How can the impacts of climate change be adjusted to or avoided; (3) What previously studied models are available for institutional management of the global environment? The resulting discussions may (1) identify worthwhile avenues for further social science research, (2) help develop feedback for natural scientists about research information from this domain needed by social scientists, and (3) provide policymakers with the sort of relevant research information from the social science community that is currently available

    Peelle, R.W.

    1982-01-01

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

    Questioning means thinking, and thinking is manifested in the form of questions. Research that studies the relationship between questioning and students’ critical thinking skills is little, if any. The aim of this study is to examine how student’s questions skill correlates to student’s critical thinking skills in learning of chemistry. The research design used was one group pretest-posttest design. The participants involved were 94 students, all of whom attended their last semesters, Chemistry Education of Tadulako University. A pre-test was administered to check participants’ ability to ask critical questions and critical thinking skills in learning chemistry. Then, the students were taught by using questioning technique. After accomplishing the lesson, a post-test was given to evaluate their progress. Obtained data were analyzed by using Pair-Samples T.Test and correlation methods. The result shows that the level of the questions plays an important role in critical thinking skills is the question levels of predictive, analysis, evaluation and inference.

    In recent years significant studies have been initiated on the theoretical and technical feasibility of utilizing a portion of the 3km S-band accelerator at the Stanford Linear Accelerator Center (SLAC) to drive a short wavelength (4.5-1.5 {Angstrom}) Linac Coherent Light Source (LCLS), a Free-Electron Laser (FEL) operating in the Self-Amplified Spontaneous Emission (SASE) regime. Electron beam requirements for single-pass saturation include: (1) a peak current in the 3-7 kA range, (2) a relative energy spread of <0.05%, ad (3) a transverse emittance, {epsilon}{le}{lambda}/4{pi}, where {lambda}[m] is the output wavelength. Requirements on the insertion device include field error levels of 0.1-0.2% for keeping the electron bunch centered on and in phase with the amplified photons, and a focusing beta of 4-8 m for inhibiting the dilution of its transverse density. Although much progress techniques necessary for LCLS operation down to {approximately}20 {angstrom}, a substantial amount of research and development is still required in a number of theoretical and experimental areas leading to the construction and operation of a 4.5-1.5 {angstrom} LCLS. In this paper we report on a research and development program underway and in planning at SLAC for addressing critical questions in these areas. These include the construction and operation of a linac test stand for developing laser-driven photocathode rf guns with normalized emittances approaching 1 mm-mr; development of advanced beam compression, stability, an emittance control techniques at multi-GeV energies; the construction and operation of a FEL Amplifier Test Experiment (FATE) for theoretical and experimental studies of SASE at IR wavelengths; an undulator development program to investigate superconducting, hybrid/permanent magnet (hybrid/PM), and pulsed-Cu technologies; theoretical and computational studies of high-gain FEL physics and LCLS component designs.

    Three ethical questions are asked and answered about the current state of affairs concerning how those in power manipulate public understanding of the effects of low doses of ionizing radiation. The questions are as follows: (1) Is it ethical to frighten people when you do not know that there is anything to be frightened of? (2) Is it ethical to be so conservative that resources are spent to solve a problem that may not exist? (3) Is it ethical not to tell the whole truth about the effects of low levels of ionizing radiation?

    The goal of the larger study was to explore physicians' emotional responses to the death of their patients; this study analyzed a subset of physician transcripts to elucidate the construct of questioning care, which emerged from the larger study. To analyzes how physicians question care-expressing concern, unease, or uncertainty about treatment decisions and practices, errors, or adverse events-as they attend dying patients. Retrospective interview study of physicians caring for randomly selected deaths on the medical service of a major academic teaching hospital, using qualitative and quantitative measures. SETTING, SUBJECTS: 188 attendings, residents, and interns on the internal medical services of two academic medical centers were part of the larger study. A subsample of 75 physician narratives was selected for qualitative data analysis for this study. Qualitative measures included open-ended questions eliciting physicians' stories of the most recent and a most emotionally powerful patient death they have experienced. Grounded theory was used to analyze physician narratives. Quantitative instruments measured physician attitudes toward end-of-life care and responses to the most recent and most emotional patient death. Physicians question care more frequently in most emotional deaths (42%) than in most recent deaths (34%). Physicians question communication with patients and families and within medical teams, medical judgment and technique, standards of practice, and high-risk treatments, often assigning responsibility for medical management they perceive as inappropriate, futile, overly aggressive, or mistakes in judgment and technique. Responsibility ranges from the distal (the culture of medicine) to the proximal (personal). Frustration, guilt, and anger are more frequently expressed in these narratives when care is questioned. A typology of questioning care emerged from these physicians' narratives that parallels and reflects recent and classic research on

    Research priorities are established to identify gaps and maximise opportunities in developing an evidence base. Numerous postgraduate research theses are undertaken each year within the specialist area of musculoskeletal physiotherapy, and although some are published, greater potential for influence exists. This paper identifies international research priorities for postgraduate theses developed using a consensual Delphi process. A purposive sample included course tutors and expert clinicians nominated by Member Organisations of the International Federation of Orthopaedic Manipulative Physical Therapists (N=91). Round 1 requested >10 priorities for theses, and content analysis identified research themes. Round 2 requested participants rank the importance of each theme on a 1-5 scale, and round 3 requested ranking the importance and feasibility of the research question areas within each agreed theme. Descriptive analysis and use of Kendall's coefficient of concordance enabled interpretation of consensus. The response rate of 68% was good, identifying 23 research themes in round 1. Round 2 identified 14 research themes as important. Participant rating of the importance and feasibility of research question areas in round 3 supported 43 agreed priorities demonstrating good measurement validity. Establishing priorities provides a vision of how postgraduate theses can contribute to the developing evidence base and offer a focus for international collaboration. Copyright 2009 Elsevier Ltd.

    2014-05-01

    Full Text Available The concept of the circular economy proposes new patterns of production, consumption and use, based on circular flows of resources. Under a scenario where there is a global shift towards the circular economy, this paper discusses the advent of two parallel and yet-to-be-connected trends for Australia, namely: (i responsible minerals supply chains and (ii additive manufacturing, also known as 3D production systems. Acknowledging the current context for waste management, the paper explores future interlinked questions which arise in the circular economy for responsible supply chains, additive manufacturing, and metals recycling. For example, where do mined and recycled resources fit in responsible supply chains as inputs to responsible production? What is required to ensure 3D production systems are resource efficient? How could more distributed models of production, enabled by additive manufacturing, change the geographical scale at which it is economic or desirable to close the loop? Examples are given to highlight the need for an integrated research agenda to address these questions and to foster Australian opportunities in the circular economy.

    Three studies (N = 990) assessed the statistical reliability of two methods of determining gender identity that can capture transgender spectrum identities (i.e., current gender identities different from birth-assigned gender categories). Study 1 evaluated a single question with four response options (female, male, transgender, other) on university students. The missing data rate was higher than the valid response rates for transgender and other options using this method. Study 2 evaluated a method of asking two separate questions (i.e., one for current identity and another for birth-assigned category), with response options specific to each. Results showed no missing data and two times the transgender spectrum response rate compared to Study 1. Study 3 showed that the two-question method also worked in community samples, producing near-zero missing data. The two-question method also identified cisgender identities (same birth-assigned and current gender identity), making it a dynamic and desirable measurement tool for the social and medical sciences.

    Fourteen ago the Wingspread Project helped establish geoscience education research (GER) as an important research field and highlighted major research questions for GER at the time. More recently, the growth and interest in GER is evident from the increase in geoscience education research articles, the establishment of the NAGT GER Division, the creation of the GER Toolbox, an increase in GER graduate programs, and the growth of tenure-eligible GER faculty positions. As an emerging STEM education research field, the GER community is examining the current state of their research and considering the best course forward so that it can have the greatest collective impact on advancing teaching and learning in the geosciences. As part of an NSF-funded effort to meet this need, 45 researchers drafted priority research questions, or "Grand Challenges", that span 10 geoscience education research themes. These include research on: students' conceptual understanding of the solid and the fluid Earth, K-12 teacher preparation, teaching about Earth in the context of societal problems, access and success of underrepresented groups in the geosciences, spatial and temporal reasoning, quantitative reasoning and use of models, instructional strategies to improve geoscience learning, students' self-regulated learning, and faculty professional development and institutional change. For each theme, several Grand Challenges have been proposed; these have undergone one round of peer-review and are now ready for the AGU community to critically examine the proposed Grand Challenges and make suggestions on strategies for addressing them: http://nagt.org/nagt/geoedresearch/grand_challenges/feedback.html. We seek perspectives from geoscience education researchers, scholars, and reflective educators. It is our vision that the final outcomes of this community-grounded process will be a published guiding framework to (1) focus future GER on questions of high interest to the geoscience education

    It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish. Research on these taxa has both underpinned many of the recent technical developments and led to fundamental discoveries in the field. We show that the questions have broad applicability to other taxa, including terrestrial animals, flying insects, and swimming invertebrates, and, as such, this exercise provides a useful roadmap for targeted deployments and data syntheses that should advance the field of movement ecology.

The transport mechanism of catalposide was investigated in HEK293 and LLC-PK1 cells overexpressing the relevant transporters. The uptake of catalposide was 319-, 13.6-, and 9.3-fold greater in HEK293 cells overexpressing OAT3, OATP1B1, and OATP1B3 transporters, respectively, than in HEK293 control cells. The increased uptake of catalposide via the OAT3, OATP1B1, and OATP1B3 transporters was decreased to basal levels in the presence of representative inhibitors such as probenecid, furosemide, and cimetidine (for OAT3 and cyclosporin A, gemfibrozil, and rifampin (for OATP1B1 and OATP1B3. The concentration-dependent OAT3-mediated uptake of catalposide revealed the following kinetic parameters: Michaelis constant (Km =41.5 µM, maximum uptake rate (Vmax =46.2 pmol/minute, and intrinsic clearance (CLint =1.11 µL/minute. OATP1B1- and OATP1B3-mediated catalposide uptake also showed concentration dependency, with low CLint values of 0.035 and 0.034 µL/minute, respectively. However, the OCT1, OCT2, OAT1, P-gp, and BCRP transporters were apparently not involved in the uptake of catalposide into cells. In addition, catalposide inhibited the transport activities of OAT3, OATP1B1, and OATP1B3 with half-maximal inhibitory concentration values of 83, 200, and 235 µ

    2012-01-01

    Full Text Available Internet research methods in nursing science are less developed than in other sciences. We choose to present an approach to conducting nursing research on an internet-based forum. This paper presents LiLEDDA, a six-step forum-based netnographic research method for nursing science. The steps consist of: 1. Literature review and identification of the research question(s; 2. Locating the field(s online; 3. Ethical considerations; 4. Data gathering; 5. Data analysis and interpretation; and 6. Abstractions and trustworthiness. Traditional research approaches are limiting when studying non-normative and non-mainstream life-worlds and their cultures. We argue that it is timely to develop more up-to-date research methods and study designs applicable to nursing science that reflect social developments and human living conditions that tend to be increasingly online-based.

    Ryan, T.G.

    1995-01-01

    This Paper reports lessons learned and state of knowledge gained from an organizational factors research activity involving commercial nuclear power plants in the United States, through the end of 1991, as seen by the scientists immediately involved in the research. Lessons learned information was gathered from the research teams and individuals using a question and answer format. The following five questions were submitted to each team and individual: (1) What organizational factors appear to influence safety performance in some systematic way, (2) Should organizational factors research focus at the plant level, or should it extend beyond the plant level to the parent company, rate setting commissions, regulatory agencies, (3) How important is having direct access to plants for doing organizational factors research, (4) What lessons have been learned to date as the result of doing organizational factors research in a nuclear regulatory setting, and (5) What organizational research topics and issues should be pursued in the future? Conclusions based on the responses provided for this report are that organizational factors research can be conducted in a regulatory setting and produce useful results. Technologies pioneered in other academic, commercial, and military settings can be adopted for use in a nuclear regulatory setting. The future success of such research depends upon the cooperation of regulators, contractors, and the nuclear industry

  14. Effect of lecture instruction on student performance on qualitative questions

    Heron, Paula R. L.

    2015-06-01

    The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to improve learning in physics courses through new curricula and instructional techniques. This paper contributes to the research base through a retrospective analysis of 20 randomly selected qualitative questions on topics in kinematics, dynamics, electrostatics, waves, and physical optics that have been given in introductory calculus-based physics at the University of Washington over a period of 15 years. In some classes, questions were administered after relevant lecture instruction had been completed; in others, it had yet to begin. Simple statistical tests indicate that the average performance of the "after lecture" classes was significantly better than that of the "before lecture" classes for 11 questions, significantly worse for two questions, and indistinguishable for the remaining seven. However, the classes had not been randomly assigned to be tested before or after lecture instruction. Multiple linear regression was therefore conducted with variables (such as class size) that could plausibly lead to systematic differences in performance and thus obscure (or artificially enhance) the effect of lecture instruction. The regression models support the results of the simple tests for all but four questions. In those cases, the effect of lecture instruction was reduced to a nonsignificant level, or increased to a significant, negative level when other variables were considered. Thus the results provide robust evidence that instruction in lecture can increase student ability to give correct answers to conceptual questions but does not necessarily do so; in some cases it can even lead to a decrease.

    Clinicians search PubMed for answers to clinical questions although it is time consuming and not always successful. To determine if PubMed used with its Clinical Queries feature to filter results based on study quality would improve search success (more correct answers to clinical questions related to therapy). We invited 528 primary care physicians to participate, 143 (27.1%) consented, and 111 (21.0% of the total and 77.6% of those who consented) completed the study. Participants answered 14 yes/no therapy questions and were given 4 of these (2 originally answered correctly and 2 originally answered incorrectly) to search using either the PubMed main screen or PubMed Clinical Queries narrow therapy filter via a purpose-built system with identical search screens. Participants also picked 3 of the first 20 retrieved citations that best addressed each question. They were then asked to re-answer the original 14 questions. We found no statistically significant differences in the rates of correct or incorrect answers using the PubMed main screen or PubMed Clinical Queries. The rate of correct answers increased from 50.0% to 61.4% (95% CI 55.0%-67.8%) for the PubMed main screen searches and from 50.0% to 59.1% (95% CI 52.6%-65.6%) for Clinical Queries searches. These net absolute increases of 11.4% and 9.1%, respectively, included previously correct answers changing to incorrect at a rate of 9.5% (95% CI 5.6%-13.4%) for PubMed main screen searches and 9.1% (95% CI 5.3%-12.9%) for Clinical Queries searches, combined with increases in the rate of being correct of 20.5% (95% CI 15.2%-25.8%) for PubMed main screen searches and 17.7% (95% CI 12.7%-22.7%) for Clinical Queries searches. PubMed can assist clinicians answering clinical questions with an approximately 10% absolute rate of improvement in correct answers. This small increase includes more correct answers partially offset by a decrease in previously correct answers.

    Full Text Available Abstract Background Missing data present a challenge to many research projects. The problem is often pronounced in studies utilizing self-report scales, and literature addressing different strategies for dealing with missing data in such circumstances is scarce. The objective of this study was to compare six different imputation techniques for dealing with missing data in the Zung Self-reported Depression scale (SDS. Methods 1580 participants from a surgical outcomes study completed the SDS. The SDS is a 20 question scale that respondents complete by circling a value of 1 to 4 for each question. The sum of the responses is calculated and respondents are classified as exhibiting depressive symptoms when their total score is over 40. Missing values were simulated by randomly selecting questions whose values were then deleted (a missing completely at random simulation. Additionally, a missing at random and missing not at random simulation were completed. Six imputation methods were then considered; 1 multiple imputation, 2 single regression, 3 individual mean, 4 overall mean, 5 participant's preceding response, and 6 random selection of a value from 1 to 4. For each method, the imputed mean SDS score and standard deviation were compared to the population statistics. The Spearman correlation coefficient, percent misclassified and the Kappa statistic were also calculated. Results When 10% of values are missing, all the imputation methods except random selection produce Kappa statistics greater than 0.80 indicating 'near perfect' agreement. MI produces the most valid imputed values with a high Kappa statistic (0.89, although both single regression and individual mean imputation also produced favorable results. As the percent of missing information increased to 30%, or when unbalanced missing data were introduced, MI maintained a high Kappa statistic. The individual mean and single regression method produced Kappas in the 'substantial agreement' range

    Full Text Available This study was aimed at examining and comparing the effectiveness of the Question-Answer Relationship (QAR and Self-Questioning (SQ strategies in improving the reading ability of the undergraduate students. This study was a quasi-experimental study in which two out of three classes of the third semester students at English department of Mataram University were selected randomly to receive either QAR strategy or SQ strategy instructions for ten weekly meetings. The findings of pre- and posttest with multiple-choice questions revealed that both comprehension strategies were effective in improving the undergraduate students‘ reading ability. The findings from the posttest with multiple-choice questions indicated the students who received SQ strategy instruction scored significantly higher than those students who received QAR strategy instruction. On the other hand, the students who received QAR strategy instruction scored slightly higher than those students who received SQ strategy instruction in the posttest with open-ended questions.

    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.

  3. Trouble in the second year: three questions about family interaction.

    Belsky, J; Woodworth, S; Crnic, K

    1996-04-01

    3 questions regarding family interaction in the second year of life are addressed in this report on 69 families rearing firstborn sons. Question 1 concerns the identification, via cluster analysis, of families having difficulty managing their child, using codings of narrative records of family interaction when children were 15 and 21 months of age. Parents in families identified as "troubled" at each age tried to control their toddlers most often, were least likely to rely upon control-plus-guidance management strategies, had children who defied them most frequently, and experienced the greatest escalation of negative affect in these control encounters. Families identified as "troubled" at both 15 and 21 months had children who received the highest "externalizing" problem scores at 18 months and mothers who experienced the most daily hassles during the second year. Question 2 concerns the antecedents of "trouble in the second year." Discriminant function analyses indicated that membership in the groups of families that appeared troubled at both ages of measurement (n = 15), at only one age (n = 28), or never (n = 26) could be reliably predicted (hit rate = 71%) using a set of 9 measurements of parent personality, child emotionality/temperament, marital quality, work-family relations, and social support, suggested by Belsky's model of the determinants of parenting, and social class. Question 3 concerns the proposition that extensive nonmaternal care in the first year is a risk factor for troubled family functioning in the second year. As hypothesized, prediction analysis showed that families at moderate and high contextual risk (based on 10 antecedent variables pertaining to Question 2), were significantly more likely to experience trouble in the second year when children experienced 20 or more hours per week of nonmaternal care in their first year, and these results could not be attributed to "selection effects."

    Final transport schemes for HIF are examined, with emphasis on transport for p>10 -3 Torr and Z>1 since this should simplify the reactor design and reduce the length of the accelerator. Specifically the question of charge neutralization is addressed. We find (1) the fractional neutralization f needed scales as f/sub i/ = (1-Z -2 ) which means f/sub i/>0.89 is needed for Z>3; (2) axially-trapped electrons limit the net beam potential to ephi/sub min/ = α(1/2 m/sub e/v/sub i/ 2 ) with 1≤αapprox. <4; (3) radially-expelled plasma ions increase f/sub i/ especially near the pellet; (4) radially-oscillating plasma electrons have and adiabatic limit of f/sub i/≅0.5; and (5) as f/sub i/ approaches unity, plasma particle trajectories may involve drift motions along and radially away from the ion beam. Also, criteria are given for the maximum Z/A allowed for transporting very large currents. For the HIF parameters used, it appears that neutralization will probably be adequte for Zapprox. <3

    Measuring attitudes and opinions employing agree/disagree (A/D) questions is a common method in social research because it appears to be possible to measure different constructs with identical response scales. However, theoretical considerations suggest that A/D questions require a considerable cognitive processing. Item-specific (IS) questions,…

    Circe (Climate change and impact research: the Mediterranean environment (www.circeproject. eu), an EC -funded 4-year research project, aims at developing for the first time a comprehensive assessment of climate change impacts in the Mediterranean area. CIRCE's rational does not take climate impacts as direct consequences of climate changes: the causal relationship is much more complex since a given climate change leads to very contrasted impacts according to existing policies as well as to socio-economic and political responses. This paper freely draws on some findings from CIRCE 's first stakeholders meeting, organised by IDDRI in October 2007. A high level, focused dialogue among a small group of selected participants, this meeting was articulated around two key questions: 1 - Business models, sector-wide transitions and socio-economic irreversibilities: is there room for manoeuvre? 2 - Succeeding where we failed: can the climate challenge be turned into an opportunity? These questions were examined with regard to three sectors (agriculture, energy and tourism) and two themes (ecosystems protection and urban and regional planning). Important cross-cutting issues for the Mediterranean such as water management, regional security, international migrations, etc., were dealt with in the discussions along the two days. (author)

    In 2008, a group of conservation scientists compiled a list of 100 priority questions for the conservation of the world's biodiversity [Sutherland et al. (2009) Conservation Biology, 23, 557-567]. However, now almost a decade later, no one has yet published a study gauging how much progress has been made in addressing these 100 high-priority questions in the peer-reviewed literature. Here we take a first step toward re-examining the 100 questions and identify key knowledge gaps that still remain. Through a combination of a questionnaire and a literature review, we evaluated each of the 100 questions on the basis of two criteria: relevance and effort. We defined highly-relevant questions as those which - if answered - would have the greatest impact on global biodiversity conservation, while effort was quantified based on the number of review publications addressing a particular question, which we used as a proxy for research effort. Using this approach we identified a set of questions that, despite being perceived as highly relevant, have been the focus of relatively few review publications over the past ten years. These questions covered a broad range of topics but predominantly tackled three major themes: the conservation and management of freshwater ecosystems, the role of societal structures in shaping interactions between people and the environment, and the impacts of conservation interventions. We see these questions as important knowledge gaps that have so far received insufficient attention and may need to be prioritised in future research. This article is protected by copyright.

  13. "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.

    Simulation-based education is a learner-active method that may enhance teamwork skills such as leadership and communication. The importance of postsimulation debriefing to promote reflection is well accepted, but many questions concerning whether and how faculty promote reflection remain largely unanswered in the research literature. The aim of this study was therefore to explore the depth of reflection expressed in questions by facilitators and responses from nursing students during postsimulation debriefings. Eighty-one nursing students and 4 facilitators participated. The data were collected in February and March 2008, the analysis being conducted on 24 video-recorded debriefings from simulated resuscitation teamwork involving nursing students only. Using Gibbs' reflective cycle, we graded the facilitators' questions and nursing students' responses into stages of reflection and then correlated these. Facilitators asked most evaluative and fewest emotional questions, whereas nursing students answered most evaluative and analytic responses and fewest emotional responses. The greatest difference between facilitators and nursing students was in the analytic stage. Only 23 (20%) of 117 questions asked by the facilitators were analytic, whereas 45 (35%) of 130 students' responses were rated as analytic. Nevertheless, the facilitators' descriptive questions also elicited student responses in other stages such as evaluative and analytic responses. We found that postsimulation debriefings provide students with the opportunity to reflect on their simulation experience. Still, if the debriefing is going to pave the way for student reflection, it is necessary to work further on structuring the debriefing to facilitate deeper reflection. Furthermore, it is important that facilitators consider what kind of questions they ask to promote reflection. We think future research on debriefing should focus on developing an analytical framework for grading reflective questions. Such

    Urea, urea-d 4 , 1,3-dimethylurea, 1,3-diethylurea powder and 1,1',3,3'-tetramethylurea, and their solutions in D 2 O were γ-irradiated with 0.0882 kGy both at room temperature and at 77 K. The product radicals were identified with X-band electron spin resonance, based on the g-factor and hyperfine coupling constants. The radicals formed from urea and urea-d 4 were identified as nitrogen-centered and resulted from N-H bond dissociation. The radicals produced from 1,3-dimethylurea, 1,3-diethylurea and 1,1',3,3'-tetramethylurea were identified as carbon-centered and resulted from C-H bond cleavage. The electron spin resonance signals of 1,3-dimethylurea, 1,3-diethylurea and 1,1',3,3'-tetramethylurea are similar in both the powder and D 2 O solution. The radicals observed from 1,3-dimethylurea, 1,3-diethylurea and 1,1',3,3'-tetramethylurea were identified as . NH-CH 2 , . NH-CHCH 3 and . (CH 3 )(CH 2 ), respectively. (author)

    This workshop was designed to bring together a group of scholars, primarily from the social sciences, to explore research that might help in dealing with global climate change. To illustrate the state of present understanding, it seemed useful to focus this workshop on three broad questions that are involved in coping with climate change. These are: (1) How can the anticipated economic costs and benefits of climate change be identified; (2) How can the impacts of climate change be adjusted to or avoided; (3) What previously studied models are available for institutional management of the global environment? The resulting discussions may (1) identify worthwhile avenues for further social science research, (2) help develop feedback for natural scientists about research information from this domain needed by social scientists, and (3) provide policymakers with the sort of relevant research information from the social science community that is currently available. Individual papers are processed separately for the database.

    Full Text Available Understanding how different types of molecules move through cell membranes is a fundamental part of cell biology. To identify and address student misconceptions surrounding molecular movement through cell membranes, we surveyed student understanding on this topic using pre-class questions, in-class clicker questions, and subsequent exam questions in a large introductory biology course. Common misconceptions identified in student responses to the pre-class assessment questions were used to generate distractors for clicker questions. Two-tier diagnostic clicker questions were used to probe incoming common student misconceptions (first tier and their reasoning (second tier. Two subsequent lectures with assessment clicker questions were used to help students construct a new framework to understand molecular movement through cell membranes. Comparison of pre-assessment and post-assessment (exam performance showed dramatic improvement in students’ understanding of molecular movement: student answers to exam questions were 74.6% correct with correct reasoning while only 1.3% of the student answers were correct with correct reasoning on the pre-class assessment. Our results show that students’ conceptual understanding of molecular movement through cell membranes progressively increases through discussions of a series of clicker questions and suggest that this clicker-based teaching strategy was highly effective in correcting common student misconceptions on this topic.

    MRI at 3 T is said to be more accurate than 1.5 T MR, but costs and other practical differences mean that it is unclear which to use. We systematically reviewed studies comparing diagnostic accuracy at 3 T with 1.5 T. We searched MEDLINE, EMBASE and other sources from 1 January 2000 to 22 October 2010 for studies comparing diagnostic accuracy at 1.5 and 3 T in human neuroimaging. We extracted data on methodology, quality criteria, technical factors, subjects, signal-to-noise, diagnostic accuracy and errors according to QUADAS and STARD criteria. Amongst 150 studies (4,500 subjects), most were tiny, compared old 1.5 T with new 3 T technology, and only 22 (15 %) described diagnostic accuracy. The 3 T images were often described as ''crisper'', but we found little evidence of improved diagnosis. Improvements were limited to research applications [functional MRI (fMRI), spectroscopy, automated lesion detection]. Theoretical doubling of the signal-to-noise ratio was not confirmed, mostly being 25 %. Artefacts were worse and acquisitions took slightly longer at 3 T. Objective evidence to guide MRI purchasing decisions and routine diagnostic use is lacking. Rigorous evaluation accuracy and practicalities of diagnostic imaging technologies should be the routine, as for pharmacological interventions, to improve effectiveness of healthcare. (orig.)

This study aimed to develop new questionnaires encompassing the most discriminative questions from existing instruments. Data from the CONTEST study, a head-to-head comparison of 3 existing questionnaires, were used to identify items with a Youden index score of ≥0.1. These were combined using 4 approaches: CONTEST (simple additions of questions), CONTESTw (weighting using logistic regression), CONTESTjt (addition of a joint manikin), and CONTESTtree (additional questions identified by classification and regression tree [CART] analysis). These candidate questionnaires were tested in independent data sets. Twelve individual questions with a Youden index score of ≥0.1 were identified, but 4 of these were excluded due to duplication and redundancy. Weighting for 2 of these questions was included in CONTESTw. Receiver operating characteristic (ROC) curve analysis showed that involvement in 6 joint areas on the manikin was predictive of PsA for inclusion in CONTESTjt. CART analysis identified a further 5 questions for inclusion in CONTESTtree. CONTESTtree was not significant on ROC curve analysis and discarded. The other 3 questionnaires were significant in all data sets, although CONTESTw was slightly inferior to the others in the validation data sets. Potential cut points for referral were also discussed. Of 4 candidate questionnaires combining existing discriminatory items to identify PsA in people with psoriasis, 3 were found to be significant on ROC curve analysis. Testing in independent data sets identified 2 questionnaires (CONTEST and CONTESTjt) that should be pursued for further prospective testing. Copyright © 2014 by the American College of Rheumatology.

  5. [Are we realistic about nursing research in nursing schools?].

    2006-12-01

    Education in nursing research in nursing schools in Switzerland has been in existence for many years but has had little impact on professional practice. This kind of education does not meet the needs of the students and the profession. Education in nursing research must be adapted, must address epistemological questions and must be integrated into the entire training programme and not only be offered at the end of the education. It could be summarised in five dimensions: 1) professional teaching founded on research results; 2) the regular reading of research papers; 3) meetings with researchers; 4) teaching of research methodology adapted to the field; and 5) a dissertation adapted to the field and considering the conditions of students' research.

    Denoting by D=2 (1/3,1/3) superalgebra; the off critical symmetry of the Φ 5/7,5/7 perturbation of the C=6/7 conformal theory, we build a new superspace solution of the (1/3,1/3) - subalgebra generated by spin ±1/3 charge operators extending the usual (1/2,1/2) supersymmetry generated by spin ±1/2 charges. This solution is based on the use of two Grassmann variables instead of one parafermionic variable θ ±1/3 satisfying the cubic nilpotency condition (θ ±1/3 ) 3 =0. Known results on the C=6/7 tricritical Potts model are recovered as special features. A relation with N=2 Landau-Ginzburg models is also discussed. (author). 17 refs, 1 tab

    To investigate whether a modest number of food frequency questions are sufficient to describe sociodemographic differences in dietary habits, and to identify sociodemographic characteristics of subjects adhering to food-based dietary guidelines operationalised in a "healthy-diet index". Cross-sectional population survey. A total of 480 men, 515 women, aged 15-90 y. Random sample of private telephone numbers drawn from regional telephone records, geographically stratified. Participation rate 62%. Computer-assisted telephone interviews, including six food frequency questions, a question on type of fat spreads used on bread, questions on seven sociodemographic variables. The summary of the healthy-diet index showed that the subjects who adhered to food-based dietary guidelines (top quintile) compared to those who did not (bottom quintile) were most often women (odds ratio (OR)=6.07; confidence interval (CI): 3.91-9.43, women vs men), of older age (OR=9.72; CI: 3.02-31.31, old age vs young), highly educated (OR=3.69; CI: 1.53-8.92, high education vs low) and living in multiperson households including children (OR=4.66; CI: 2.47-8.80, multiperson household vs single household). The results also showed that gender difference in dietary habits is associated with other sociodemographic variables. The selected food frequency questions proved sufficient to describe sociodemographic differences in dietary habits, and this method may be a valuable supplement to traditional quantitative dietary surveys in monitoring sociodemographic changes in eating patterns. The results also underline the influence of sociodemographic status on dietary habits. The Danish Nutrition Council funded the study.

    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.

  9. Analysis of students’ generated questions in laboratory learning environments

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available In order to attain a reliable laboratory work assessment, we argue taking the Learning Environment as a core concept and a research paradigm that considers the factors affecting the laboratory as a particularly complex educational context. With regard to Laboratory Learning Environments (LLEs, a well known approach is the SLEI (Science Laboratory Environment Inventory. The aim of this research is to design and apply an alternative and qualitative assessment tool to characterize Laboratory Learning Environments in an introductory course of organic chemistry. An alternative and qualitative assessment tool would be useful for providing feed-back for experimental learning improvement; serving as a complementary triangulation tool in educational research on LLEs; and generating meaningful categories in order to design quantitative research instruments. Toward this end, spontaneous questions by students have been chosen as a reliable source of information. To process these questions, a methodology based on the Grounded Theory has been developed to provide a framework for characterizing LLEs. This methodology has been applied in two case studies. The conclusions lead us to argue for using more holistic assessment tools in both everyday practice and research. Likewise, a greater attention should be paid to metacognition to achieve suitable self-perception concerning students’ previous knowledge and manipulative skills.

  13. On Nuclear Molecules Built up from sup 1 sup 3 sup 2 Sn Components

    CERN Document Server

    Swiatecki, W J

    2003-01-01

    The possible existence of nuclear quasi-molecules built up from sup 1 sup 3 sup 2 Sn components is investigated. The crucial question is whether the extra stability of the doubly magic sup 1 sup 3 sup 2 Sn nuclei makes them sufficiently rigid to be able to withstand the strains imposed by their mutual interactions. It is argued that if the simplest quasi-molecular dumbbell configuration were found to be (meta-)stable, then triangular and even tetrahedral structures might have comparable barriers against disintegration and comparable spontaneous fission lifetimes. These are estimated using simplifying assumptions. As regards the dumbbell's stability, one may relate this to the existence of a potential energy pocket in the deformation energy landscape of a fissioning sup 2 sup 6 sup 4 Fm nucleus, and to the presence of ''bimodal'' fission in heavy Fm isotopes. Further experimental and theoretical studies of such systems may be relevant for answering the question concerning nuclear quasi-molecules.

  16. Immigration and Competitiveness – Some Methodological Questions

    Directory of Open Access Journals (Sweden)

    Tünde Patay

    2017-12-01

    Full Text Available Immigrants can contribute significantly to the economic and social development of regions or urban areas. Some key figures on migration are thus traditionally used in studies on local development. Beyond the usual description of migratory movements, two research fields are often in the centre of controversies, namely the labour market and the inclusion of immigrants. Comparing the European regions, the phases of urban development as well as the relevant internal and external factors present a mixed picture in Europe. At the same time, the dynamics of migratory movements and the reactions of national and subnational policies also vary. The Member States of the European Union aim to harmonise their definitions and data on migration issues, however, the daily practice leads us to the questions of reliability and comparability of migration statistics; and the interdisciplinary character of migration research offers the use of variable research methods. The aim of this study, as a part of a presentation at a conference on urban development, is to describe some key methodological issues of migration research exploring the typical questions. The first part of the paper calls attention to the importance of data quality, processing and interpretation, describing the research methods mainly used in studies on immigration. The second part summarizes the significance of immigration in regional competitiveness, pointing out the possible “stumbling stones” in the relevant migration studies. Some of these factors, the areas that are mainly in the centre of scientific and political debates, are discussed in this paper, namely the labour market challenges and issues relating to the different aspects of segregation.

  19. Two questions about surrogacy and exploitation.

    Science.gov (United States)

    Wertheimer, Alan

    1992-01-01

    In this article I will consider two related questions about surrogacy and exploitation: (1) Is surrogacy exploitative? (2) If surrogacy is exploitative, what is the moral force of this exploitation? Briefly stated, I shall argue that whether surrogacy is exploitative depends on whether exploitation must be harmful to the exploited party or whether (as I think) there can be mutually advantageous exploitation. It also depends on some facts about surrogacy about which we have little reliable evidence and on our philosophical view on what counts as a harm to the surrogate. Our answer to the second question will turn in part on the account of exploitation we invoke in answering the first question and in part on the way in which we resolve some other questions about the justification of state interference. I shall suggest, however, that if surrogacy is a form of voluntary and mutually advantageous exploitation, then there is a strong presumption that surrogacy contracts should be permitted and even enforceable, although that presumption may be overridden on other grounds.

    Over the last decade, 1,2,3-triazoles have received increasing attention in medicinal chemistry thanks to the discovery of the highly useful and widely applicable 1,3-dipolar cycloaddition reaction between azides and alkynes (click chemistry) catalyzed by copper salts and ruthenium complexes. After a decade of medicinal chemistry research on 1,2,3-triazoles, we feel that the time is ripe to demonstrate the real ability of this heterocycle to participate in important and pivotal binding interactions with biological targets while maintaining a good pharmacokinetic profile. In this study, we retrieved and analyzed X-ray crystal structures of complexes between 1,2,3-triazoles and either proteins or DNA to understand the pharmacophoric role of the triazole. Furthermore, the metabolic stability, the capacity to inhibit cytochromes, and the contribution of 1,2,3-triazoles to the overall aqueous solubility of compounds containing them have been analyzed. This information should furnish fresh insight for medicinal chemists in the design of novel bioactive molecules that contain the triazole nucleus. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  2. Entanglement entropy for (3+1)-dimensional topological order with excitations

    2018-02-01

    Excitations in (3+1)-dimensional [(3+1)D] topologically ordered phases have very rich structures. (3+1)D topological phases support both pointlike and stringlike excitations, and in particular the loop (closed string) excitations may admit knotted and linked structures. In this work, we ask the following question: How do different types of topological excitations contribute to the entanglement entropy or, alternatively, can we use the entanglement entropy to detect the structure of excitations, and further obtain the information of the underlying topological order? We are mainly interested in (3+1)D topological order that can be realized in Dijkgraaf-Witten (DW) gauge theories, which are labeled by a finite group G and its group 4-cocycle ω ∈H4[G ;U(1 ) ] up to group automorphisms. We find that each topological excitation contributes a universal constant lndi to the entanglement entropy, where di is the quantum dimension that depends on both the structure of the excitation and the data (G ,ω ) . The entanglement entropy of the excitations of the linked/unlinked topology can capture different information of the DW theory (G ,ω ) . In particular, the entanglement entropy introduced by Hopf-link loop excitations can distinguish certain group 4-cocycles ω from the others.

  3. Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions

    Directory of Open Access Journals (Sweden)

    D’Ammando F.

    2013-12-01

    Full Text Available Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies. The first four years of observations by the Large Area Telescope on board Fermi confirmed that these two are the most numerous classes of identified sources in the extragalactic γ-ray sky, but the discovery of γ-ray emission from 5 radio-loud narrow-line Seyfert 1 galaxies revealed the presence of a possible emerging third class of AGNs with relativistic jets. Considering that narrow-line Seyfert 1 galaxies seem to be typically hosted in spiral galaxy, this finding poses intriguing questions about the nature of these objects, the onset of production of relativistic jets, and the cosmological evolution of radio-loud AGN. Here, we discuss the radio-to-γ-rays properties of the γ-ray emitting narrow-line Seyfert 1 galaxies, also in comparison with the blazar scenario.

    The helical duplex architecture of DNA was discovered by Francis Crick and James Watson in 1951 and is well known and understood. However, nucleic acids can also adopt alternative structural conformations that are less familiar, although no less biologically relevant, such as the G-quadruplex. G-quadruplexes continue to be the subject of a rapidly expanding area of research, owing to their significant potential as therapeutic targets and their unique biophysical properties. This review begins by focusing on G-quadruplex structure, elucidating the intermolecular and intramolecular interactions underlying its formation and highlighting several substructural variants. A variety of methods used to characterize these structures are also outlined. The current state of G-quadruplex research is then addressed by proffering seven pertinent questions for discussion. This review concludes with an overview of possible directions for future research trajectories in this exciting and relevant field.

    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

    2017-01-01

    To establish global research priorities for interpersonal violence prevention using a systematic approach. Research priorities were identified in a three-round process involving two surveys. In round 1, 95 global experts in violence prevention proposed research questions to be ranked in round 2. Questions were collated and organized according to the four-step public health approach to violence prevention. In round 2, 280 international experts ranked the importance of research in the four steps, and the various substeps, of the public health approach. In round 3, 131 international experts ranked the importance of detailed research questions on the public health step awarded the highest priority in round 2. In round 2, "developing, implementing and evaluating interventions" was the step of the public health approach awarded the highest priority for four of the six types of violence considered (i.e. child maltreatment, intimate partner violence, armed violence and sexual violence) but not for youth violence or elder abuse. In contrast, "scaling up interventions and evaluating their cost-effectiveness" was ranked lowest for all types of violence. In round 3, research into "developing, implementing and evaluating interventions" that addressed parenting or laws to regulate the use of firearms was awarded the highest priority. The key limitations of the study were response and attrition rates among survey respondents. However, these rates were in line with similar priority-setting exercises. These findings suggest it is premature to scale up violence prevention interventions. Developing and evaluating smaller-scale interventions should be the funding priority.

    One important challenge ahead for sport and exercise pedagogy (SEP) researchers is to consider afresh questions about learning. Learning in the fields of sport, physical activity and physical education (PE) is a particularly complex business. Most existing theories of learning are defined cognitively, yet learning in sport and physical activity…

  18. Testing for Questionable Research Practices in a Meta-Analysis: An Example from Experimental Parapsychology.

    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.

    MRI at 3 T is said to be more accurate than 1.5 T MR, but costs and other practical differences mean that it is unclear which to use. We systematically reviewed studies comparing diagnostic accuracy at 3 T with 1.5 T. We searched MEDLINE, EMBASE and other sources from 1 January 2000 to 22 October 2010 for studies comparing diagnostic accuracy at 1.5 and 3 T in human neuroimaging. We extracted data on methodology, quality criteria, technical factors, subjects, signal-to-noise, diagnostic accuracy and errors according to QUADAS and STARD criteria. Amongst 150 studies (4,500 subjects), most were tiny, compared old 1.5 T with new 3 T technology, and only 22 (15 %) described diagnostic accuracy. The 3 T images were often described as ''crisper'', but we found little evidence of improved diagnosis. Improvements were limited to research applications [functional MRI (fMRI), spectroscopy, automated lesion detection]. Theoretical doubling of the signal-to-noise ratio was not confirmed, mostly being 25 %. Artefacts were worse and acquisitions took slightly longer at 3 T. Objective evidence to guide MRI purchasing decisions and routine diagnostic use is lacking. Rigorous evaluation accuracy and practicalities of diagnostic imaging technologies should be the routine, as for pharmacological interventions, to improve effectiveness of healthcare. (orig.)

    Prioritizing comparative effectiveness research may contribute to obtaining answers that clinicians perceive they need and may minimize research that could be considered wasteful. Our objective was to identify evidence gaps and set priorities for new systematic reviews and randomized controlled trials for managing diabetic retinopathy (DR), including diabetic macular edema (DME). Cross-sectional study. Diabetic Retinopathy Clinical Research Network (DRCR.net) investigators. We provided recommendations from the American Academy of Ophthalmology's 2012 Preferred Practice Patterns for Diabetic Retinopathy as 91 answerable clinical research questions about intervention effectiveness to 410 DRCR.net investigators to rate each question's importance from 0 (not important) to 10 (very important) using a 2-round Delphi survey and to suggest additional questions. We considered questions as high priority if at least 75% of respondents to both rounds assigned an importance rating of 5 or more in round 2. We also extracted outcome measures relevant to DR and asked respondents to identify those that must be measured in all studies. We mapped Cochrane reviews published up to March 2016 to high-priority clinical research questions. Ranking of importance of each clinical question. Thirty-two individuals completed rounds 1 and 2 and suggested 15 questions. Among the final list of 106 clinical research questions, 22 questions met our definition of high priority: 9 of 22 concerned the effectiveness of anti-VEGF therapy, and 13 of 22 focused on how often patients should be followed up (re-examination) and treatment effectiveness in patients with specific characteristics (e.g., DME). Outcomes that 75% or more of respondents marked as "must be measured in all studies" included visual acuity and visual loss, death of participants, and intraocular pressure. Only 1 prioritized question was associated with conclusive evidence from a Cochrane systematic review. A limited response rate among

    In the fast pace of the Emergency Department (ED), clinicians are in need of tailored screening tools to detect seniors who are at risk of adverse outcomes. We aimed to explore the usefulness of the Bergman-Paris Question (BPQ) to expose potential undetected geriatric syndromes in community-living seniors presenting to the ED. This is a planned sub-study of the INDEED multicentre prospective cohort study, including independent or semi-independent seniors (≥65 years old) admitted to hospital after an ED stay ≥8 hours and who were not delirious. Patients were assessed using validated screening tests for 3 geriatric syndromes: cognitive and functional impairment, and frailty. The BPQ was asked upon availability of a relative at enrolment. BPQ's sensitivity and specificity analyses were used to ascertain outcomes. A response to the BPQ was available for 171 patients (47% of the main study's cohort). Of this number, 75.4% were positive (suggesting impairment), and 24.6% were negative. To detect one of the three geriatric syndromes, the BPQ had a sensitivity of 85.4% (95% CI [76.3, 92.0]) and a specificity of 35.4% (95% CI [25.1, 46.7]). Similar results were obtained for each separate outcome. Odds ratio demonstrated a higher risk of presence of geriatric syndromes. The Bergman-Paris Question could be an ED screening tool for possible geriatric syndrome. A positive BPQ should prompt the need of further investigations and a negative BPQ possibly warrants no further action. More research is needed to validate the usefulness of the BPQ for day-to-day geriatric screening by ED professionals or geriatricians.

    Unhealthy alcohol use is prevalent but under-diagnosed in primary care settings. To validate, in primary care, a single-item screening test for unhealthy alcohol use recommended by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Cross-sectional study. Adult English-speaking patients recruited from primary care waiting rooms. Participants were asked the single screening question, “How many times in the past year have you had X or more drinks in a day?”, where X is 5 for men and 4 for women, and a response of 1 or greater [corrected] is considered positive. Unhealthy alcohol use was defined as the presence of an alcohol use disorder, as determined by a standardized diagnostic interview, or risky consumption, as determined using a validated 30-day calendar method. Of 394 eligible primary care patients, 286 (73%) completed the interview. The single-question screen was 81.8% sensitive (95% confidence interval (CI) 72.5% to 88.5%) and 79.3% specific (95% CI 73.1% to 84.4%) for the detection of unhealthy alcohol use. It was slightly more sensitive (87.9%, 95% CI 72.7% to 95.2%) but was less specific (66.8%, 95% CI 60.8% to 72.3%) for the detection of a current alcohol use disorder. Test characteristics were similar to that of a commonly used three-item screen, and were affected very little by subject demographic characteristics. The single screening question recommended by the NIAAA accurately identified unhealthy alcohol use in this sample of primary care patients. These findings support the use of this brief screen in primary care.

    Full Text Available 1-3 type, 1-3-2 type and 2-1-3 type piezoelectric composites are three proper smart materials for the design and manufacture of ultrasonic transducers. They have been proposed in different stages but possess similar properties. Compared with the initial 1-3 type composite, 1-3-2 composite is of higher mechanical stability. Compared with 1-3-2 composite, 2-1-3 composite has lower manufacturing difficulty. In this paper, a comparative study on these three composites in terms of receiving transducer material properties is presented. Finite element method (FEM has been adopted to calculate longitudinal velocity, thickness electromechanical coupling coefficient and voltage receiving sensitivity. It is concluded that for a large aspect ratio α=1, the performance of 2-1-3 composite transducer is much better than that of 1-3 and 1-3-2 composite transducers. The thickness electromechanical coupling coefficient of 2-1-3 composite transducer is about 5.58 times that of 1-3 composite transducer and 7.42 times that of 1-3-2 composite transducer. The voltage receiving sensitivity at 2 kHz of 2-1-3 composite transducer is 13.1 dB higher than that of 1-3-2 composite transducer and 12.3 dB higher than that of 1-3 composite transducer.

    The first Thai Research Reactor, TRR-1 went critical on 27 October 1962 at the maximum power of 1 MW. It was located at Office of Atoms for Peace (OAP) in Bangkok. Since then, TRR-1 was continuously operated and eventually shut down in 1975. Plate type, high-enriched uranium (HEU) and U 3 O 8 A1 cladding were used as the reactor fuel. Light water was used as moderator and coolant as well. In 1975, because of the problem from fuel supplier and also to supporting the Treaty of Non Proliferation of Nuclear Weapon or NPT, TRR-1 was shut down for modification. The reactor core and control system were disassembled and replaced by TRIGA Mark III. A new core was a hexagonal core shape designed by General Atomics (GA). Afterwards, TRR-1 was officially renamed to the Thai Research Reactor-1/Modification 1 (TRR-1/M1). TRR-1/M1 is a multipurpose swimming pool type reactor with nominal power of 2 MW. The TRR-1/M1 uses uranium enriched at 20% in U-235 (LEU) and ZrH alloy as fuel. Light water is also used as coolant and moderator. At present, the reactor is operating with core No.14. The reactor has been serving for various kinds of utilization namely, radioisotope production, neutron activation analysis, beam experiments and reactor physics experiments. (author)

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available There is evidence that survey interviewers may be tempted to manipulate answers to filter questions in a way that minimizes the number of follow-up questions. This becomes relevant when ego-centered network data are collected. The reported network size has a huge impact on interview duration if multiple questions on each alter are triggered. We analyze interviewer effects on a network-size question in the mixed-mode survey “Panel Study ‘Labour Market and Social Security’” (PASS, where interviewers could skip up to 15 follow-up questions by generating small networks. Applying multilevel models, we find almost no interviewer effects in CATI mode, where interviewers are paid by the hour and frequently supervised. In CAPI, however, where interviewers are paid by case and no close supervision is possible, we find strong interviewer effects on network size. As the area-specific network size is known from telephone mode, where allocation to interviewers is random, interviewer and area effects can be separated. Furthermore, a difference-in-difference analysis reveals the negative effect of introducing the follow-up questions in Wave 3 on CAPI network size. Attempting to explain interviewer effects we neither find significant main effects of experience within a wave, nor significantly different slopes between interviewers.

    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.

    2014-06-01

    Full Text Available Smaller expansions (41–54 CGG repeats in the fragile X mental retardation 1 (FMR1 gene are termed "gray zone" alleles. Only recently has interest in these expansions increased due to reporting of phenotypes unique to gray zone carriers or similar to those seen in individuals with larger expansions. As minimal research has focused on gray zone expansions, this paper asks several questions related to this topic. These include the following: What is the definition of the gray zone? Is there a risk of developing neurological signs in these carriers? Are there secondary gene effects that impact gray zone alleles or a biologic advantage to carrying these repeats? How do we counsel patients with gray zone expansions? The answers to these questions will help to determine the significance of these expansions and provide needed information to the research community and clinicians.

    The Interagency Committee on Human Nutrition Research (ICHNR) is charged with improving the planning, coordination, and communication among federal agencies engaged in nutrition research and with facilitating the development and updating of plans for federal research programs to meet current and future domestic and international needs for nutrition. The ICHNR is co-chaired by the USDA Under Secretary for Research, Education, and Economics and Chief Scientist and the US Department of Health and Human Services Assistant Secretary for Health and is made up of >10 departments and agencies. Once the ICHNR was reassembled after a 10-y hiatus, the ICHNR recognized a need for a written roadmap to identify critical human nutrition research gaps and opportunities. This commentary provides an overview of the process the ICHNR undertook to develop a first-of-its-kind National Nutrition Research Roadmap, which was publicly released on 4 March 2016. The primary audience for the Roadmap is federal science agency leaders, along with relevant program and policy staff who rely on federally supported human nutrition research, in addition to the broader scientific community. The Roadmap is framed around the following 3 questions: 1 ) How can we better understand and define eating patterns to improve and sustain health? 2 ) What can be done to help people choose healthy eating patterns? 3 ) How can we develop and engage innovative methods and systems to accelerate discoveries in human nutrition? Within these 3 questions, 11 topical areas were identified on the basis of the following criteria: population impact, feasibility given current technological capacities, and emerging scientific opportunities. This commentary highlights initial federal and some professional research society efforts to address the Roadmap's research and resource priorities. We conclude by noting examples of early collaborations and partnerships to move human nutrition research forward in the 21st century. © 2017

    A thulium(III) membrane sensor was made using 2% sodium tetraphenyl borate (NaTPB), 65% dibutylphthalate (DBP), 30% poly(vinyl chloride) (PVC) and 3% 1-ethyl-3-(2,5-dihydro-4-(3,5-dimethyl-1H-pyrazol-4-yl) -5-oxo-1H-pyrazol-3-yl)thiourea (ET) as an ionophore. Conductometric study shows selectivity of the Et toward Tm 3+ ions. Nernstian response of 19.6 ± 0.4 mV per decade of thulium concentration was observed, and the electrode worked well in concentration range of 1.0 x 10 -6 to 1.0 x 10 -2 mol L -1 with a lower detection limit (LDL) of 7.2 x 10 -7 mol L -1 , in a pH range of 4.3-10.4. The selectivity of the sensor over alkaline, alkaline earth, transition and heavy metal ions was also found to be in a satisfactory range. To check the analytical applicability of the proposed Tm 3+ sensor, it was successfully used as an indicator electrode in analysis of thulium in certified reference materials. - Research highlights: → This work reports development of polymeric membrane sensor for Tm3+ determination in certified reference materials. → The novelty of this work is based on the high affinity of the ionophore toward the Tm3+ ions which causes the high selectivity of the sensor. → The newly developed sensor is superior to the formerly reported Tm3+ sensors in terms of selectivity and detection limit.

    Hazardous drinking and alcohol use disorders (i.e, abuse and dependence) are common in Emergency Departments (EDs). This study examined 1) the prevalence of these conditions among ED patients and 2) characteristics of a single screening question (having consumed at least five drinks for males or four for females during a single day). Data from the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Logistic regression for clustered data was used to estimate the relative risk for past-year ED use associated with hazardous drinking, abuse, and dependence. Contingency tables were analyzed to estimate the sensitivity and specificity of the single-question screen for detecting these conditions. Hazardous drinking was not associated with ED utilization. Alcohol abuse was associated with a relative risk of 1.3 (95% confidence interval [CI] 1.1-1.5) and alcohol dependence with a relative risk of 1.9 (95% CI 1.6-2.2). For current drinkers, the single question screen was 0.96, 0.85, and 0.90 sensitive for hazardous drinking, alcohol abuse, and alcohol dependence, respectively. Individuals with a positive screen in the past year were considered at least hazardous drinkers, and specificity was 0.80, 0.64, and 0.65 for hazardous drinking, abuse, and dependence, respectively. Specificity was modestly increased in women. Most problem drinkers were hazardous drinkers, but only severe alcohol use disorders were particularly prevalent in the ED. The single heavy-drinking-day item appears sensitive for problem drinking. Positive tests must be followed by additional assessment to differentiate hazardous drinking from alcohol use disorders.

    In a single one-hour session, first-year medical students were taught a framework for differentiating between lower-order questions that lead to knowledge of facts and higher-order questions that lead to integration of concepts and deeper learning, thereby preparing them for problem-based learning (PBL). Students generated lists of questions in response to an assertion prompt and categorized them according to Bloom's Taxonomy. These data were analyzed in addition to data from the course exam, which asked them to formulate a higher-level question in response to a prompt. Categorizing questions according to Bloom's Taxonomy was a more difficult task for students than was formulating higher-order questions. Students reported that the skills that they learned were used in subsequent PBL sessions to formulate higher-order learning objectives that integrated new and previously-learned concepts.

    NUREG/CR-6204 is a collection of questions and answers that were originally issued in seven sets and which pertain to revised 10 CFR Part 20. The questions came from both outside and within the NRC. The answers were compiled and provided by NRC staff within the offices of Nuclear Reactor Regulation, Nuclear Material Safety and Safeguards, Nuclear Regulatory Research, the Office of State Programs, and the five regional offices. Although all of the questions and answers have been reviewed by attorneys in the NRC Office of the General Counsel, they do not constitute official legal interpretations relevant to revised 10 CFR Part 20. The questions and answers do, however, reflect NRC staff decisions and technical options on aspects of the revised 10 CFR Part 20 regulatory requirements. This NUREG is being made available to encourage communication among the public, industry, and NRC staff concerning the major revisions of the NRC's standards for protection against radiation

    There are a number of anecdotal reports on demographic characteristics and academic success of accelerated-nursing students; yet few empirical studies have examined accelerated-nursing students NCLEX-RN success. Applying Knowles' adult learning theory as a guiding framework, the purpose of this qualitative study was to explore, from the accelerated-nursing students' perspective, the factors reported as contributing to their success on the NCLEX-RN. The research questions aimed to elicit participants' descriptions of their experiences and factors contributing to their success via individual interviews. The most significant finding the participants identified as the factor that contributed to their success was the practicing of NCLEX-RN questions. The findings of this study have several implications for educational policy and practice for universities and schools of nursing as the information gained from this study applies to recruitment and retention as well as curriculum and educational strategies in an accelerated-nursing program.

    The research focuses on the phenomenon of pressure induced amorphization (PIA) in Ln1/3MO3, Ln - La,Pr,Nd and M-Nb,Ta. In most pressure induced phase transitions the material changes from a crystalline phase to another crystalline phase. However, if this transition is kinetically hindered, the increased free energy due to the applied pressure will result in a structural collapse to an amorphous intermediate phase. This phenomenon is known as pressure induced amorphization

  17. Draft WNP-1 [Washington Nuclear Plant] and -3 study: 1987 resource strategy

    1986-01-01

    With this study Bonneville seeks to conclude whether WNP-1 and -3 should be preserved, terminated, or completed on a fixed construction schedule. Bonneville has completed an intensive review and analysis of issues related to this question. Bonneville's draft study conclusion is that preserving both WNP-1 and -3 is the most prudent course of action in the short run, pending the resolution of several critical factors. This conclusion is based on the following key study findings. Bonneville found that, economically, continued preservation is the lower-risk alternative. Termination creates the risk that the region would have to eventually build new coal plants, costing over $2 billion more in present value than completing WNP-1 and -3. Alternatively, preservation creates the smaller risk that preservation costs, amounting to $150 million in present value, will be spent over the next 14 years on projects that turn out not to be needed

The benefits and challenges of using EMR in general health research have been investigated; however, the utility of EMR for oncology outcomes research has not been explored. Compared to current available oncology databases and registries, an oncology-specific EMR could provide comprehensive and accurate information on clinical diagnoses, personal and medical histories, planned and actual treatment regimens, and post-treatment outcomes, to address research questions from patients, policy makers, the pharmaceutical industry, and clinicians/researchers. Specific challenges related to structural (eg, interoperability, data format/entry, clinical (eg, maintenance and continuity of records, variety of coding schemes, and research-related (eg, missing data, generalizability, privacy issues must be addressed when building an oncology-specific EMR system. Researchers should engage with medical professional groups to guide development of EMR systems that would ultimately help improve the quality of cancer care through oncology outcomes research.Keywords: medical informatics, health care, policy, outcomes
