    Sahyun, S. C.; Gardner, J. A.

    1999-05-01

    The method of creating auditory graphs by mapping the y axis to pitch and the x axis to time, the inclusion of drum beats to mark first and second derivative information, and tonality changes to indicate negative values is demonstrated to be an effective technique for displaying graphical information to students. While not a perfect replacement for the visual graph, students with very little training could effectively use auditory graphs to answer multiple choice physics and math questions. Student performance for the group using only auditory graphs is shown to be 80% of the level attained by subjects using visually presented graphs.

  14. Examining the Impact of Question Surface Features on Students’ Answers to Constructed-Response Questions on Photosynthesis

    2015-01-01

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

    1983-01-01

    The natural language database query system incorporated in the Knobs Interactive Planning System comprises a dictionary driven parser, APE-II, and script interpreter whch yield a conceptual dependency as a representation of the meaning of user input. A conceptualisation pattern matching production system then determines and executes a procedure for extracting the desired information from the database. In contrast to syntax driven q-a systems, e.g. those based on atn parsers, APE-II is driven bottom-up by expectations associated with word meanings. The goals of this approach include utilising similar representations for questions with similar meanings but widely varying surface structures, developing a powerful mechanism for the disambiguation of words with multiple meanings and the determination of pronoun referents, answering questions which require inferences to be understood, and interpreting ellipses and ungrammatical statements. The Knobs demonstration system is an experimental, expert system for air force mission planning applications. 16 refs.

  18. The methods that college students use to answer questions about stereochemistry involving spatial ability

    NASA Astrophysics Data System (ADS)

    Strange de Soria, Luise Ethelyn

    Introduction. The research problem investigated involved determining the spatial techniques used by students when they solved problems relating to stereochemistry using both traditional and non-traditional techniques. The main reason for undertaking this study was to determine how to help students invoke their spatial ability in solving problems during their organic chemistry courses. The project allowed students to generate their own understanding of the material, to gain experience in order to increase their knowledge, and to be actively involved in the learning process in order for true understanding to take place. Methods. The qualitative methodology for the project included a background questionnaire and the Purdue Visualization of Rotations Exam to determine the five students to be interviewed. The class participated in three multimedia lectures, an in-class assignment, and an on-line homework activity, which allowed multiple ways of incorporating the material. These activities included hand-drawing structures, making non-traditional models as well as traditional models, and computer related exercises that required differing aspects of spatial ability and engagement. Five students participated in an individual and small group interview in which rotation ability as well as visualization ability was assessed using physical molecular models as well as computer models. Results. This study is significant for the field of science education and chemistry because it determined that students with varying levels of spatial ability preferred different tools and used different skills when answering questions about stereochemistry that require spatial ability. There was a pronounced difference in the ability of low and high spatial ability students to draw and make structures that required three-dimensional aspects. A distinct preference for working with the physical model kit over the computer-enhanced program was also noted. An online resource for instructors and students of organic chemistry to use when studying stereochemistry was developed during the project. Conclusions. The potential impact on teaching and learning is that other instructors of chemistry will be able to develop problems and training sessions for their specific students that are "tailor made" to fit their students' abilities and interests. Consequently, students with either high or low spatial ability can work problems with tools that best fit their skills.

  4. Use of Feedback-Oriented Online Exercises to Help Physiology Students Construct Well-Organized Answers to Short-Answer Questions

    PubMed Central

    2015-01-01

    Postsecondary education often requires students to use higher-order cognitive skills (HOCS) such as analysis, evaluation, and creation as they assess situations and apply what they have learned during lecture to the formulation of solutions. Summative assessment of these abilities is often accomplished using short-answer questions (SAQs). Quandary was used to create feedback-oriented interactive online exercises to help students strengthen certain HOCS as they actively constructed answers to questions concerning the regulation of 1) metabolic rate, 2) blood sugar, 3) erythropoiesis, and 4) stroke volume. Each exercise began with a SAQ presenting an endocrine dysfunction or a physiological challenge; students were prompted to answer between six and eight multiple-choice questions while building their answer to the SAQ. Student outcomes on the SAQ sections of summative exams were compared before and after the introduction of the online tool and also between subgroups of students within the posttool-introduction population who demonstrated different levels of participation in the online exercises. While overall SAQ outcomes were not different before and after the introduction of the online exercises, once the SAQ tool had become available, those students who chose to use it had improved SAQ outcomes compared with those who did not.

    We conducted a controlled investigation to examine whether a combination of computer imagery and tactile tools helps introductory cell biology laboratory undergraduate students better learn about protein structure/function relationships as compared with computer imagery alone. In all five laboratory sections, students used the molecular imaging program, Protein Explorer (PE). In the three experimental sections, three-dimensional physical models were made available to the students, in addition to PE. Student learning was assessed via oral and written research summaries and videotaped interviews. Differences between the experimental and control group students were not found in our typical course assessments such as research papers, but rather were revealed during one-on-one interviews with students at the end of the semester. A subset of students in the experimental group produced superior answers to some higher-order interview questions as compared with students in the control group. During the interview, students in both groups preferred to use either the hand-held models alone or in combination with the PE imaging program. Students typically did not use any tools when answering knowledge (lower-level thinking) questions, but when challenged with higher-level thinking questions, students in both the control and experimental groups elected to use the models.

  2. Answering Key Fuel Cycle Questions

    Piet, S.J.; Dixon, B.W.; Bennett, R.G.; Smith, J.D.; Hill, R.N.

    2004-10-03

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

    The Advanced Fuel Cycle Initiative (AFCI) program has both “outcome” and “process” goals because it must address both waste already accumulating as well as completing the fuel cycle in connection with advanced nuclear power plant concepts. The outcome objectives are waste geological repository capacity and cost, energy security and sustainability, proliferation resistance, fuel cycle economics, and safety. The process objectives are readiness to proceed and adaptability and robustness in the face of uncertainties. A classic decision-making approach to such a multi-attribute problem would be to weight individual quantified criteria and calculate an overall figure of merit. This is inappropriate for several reasons. First, the goals are not independent. Second, the importance of different goals varies among stakeholders. Third, the importance of different goals is likely to vary with time, especially the “energy future.” Fourth, some key considerations are not easily or meaningfully quantifiable at present. Instead, at this point, we have developed 16 questions the AFCI program should answer and suggest an approach of determining for each whether relevant options improve meeting each of the program goals. We find that it is not always clear which option is best for a specific question and specific goal; this helps identify key issues for future work. In general, we suggest attempting to create as many win-win decisions (options that are attractive or neutral to most goals) as possible. Thus, to help clarify why the program is exploring the options it is, and to set the stage for future narrowing of options, we have developed 16 questions, as follows: · What are the AFCI program goals? · Which potential waste disposition approaches do we plan for? · What are the major separations, transmutation, and fuel options? · How do we address proliferation resistance? · Which potential energy futures do we plan for? · What potential external triggers do we plan for? · Should we separate uranium? · If we separate uranium, should we recycle it, store it or dispose of it? · Is it practical to plan to fabricate and handle “hot” fuel? · Which transuranic elements (TRU) should be separated and transmuted? · Of those TRU separated, which should be transmuted together? · Should we separate and/or transmute Cs and Sr isotopes that dominate near-term repository heating? · Should we separate and/or transmute very long-lived Tc and I isotopes? · Which separation technology? · What mix of transmutation technologies? · What fuel technology best supports the above decisions?

    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.

  15. Beyond Information Retrieval—Medical Question Answering

    PubMed Central

    Lee, Minsuk; Cimino, James; Zhu, Hai Ran; Sable, Carl; Shanker, Vijay; Ely, John; Yu, Hong

    2006-01-01

    Physicians have many questions when caring for patients, and frequently need to seek answers for their questions. Information retrieval systems (e.g., PubMed) typically return a list of documents in response to a user’s query. Frequently the number of returned documents is large and makes physicians’ information seeking “practical only ‘after hours’ and not in the clinical settings”. Question answering techniques are based on automatically analyzing thousands of electronic documents to generate short-text answers in response to clinical questions that are posed by physicians. The authors address physicians’ information needs and described the design, implementation, and evaluation of the medical question answering system (MedQA). Although our long term goal is to enable MedQA to answer all types of medical questions, currently, we currently implement MedQA to integrate information retrieval, extraction, and summarization techniques to automatically generate paragraph-level text for definitional questions (i.e., “What is X?”). MedQA can be accessed at http://www.dbmi.columbia.edu/~yuh9001/research/MedQA.html. PMID:17238385

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

  8. Towards a medical question-answering system: a feasibility study.

    Jacquemart, Pierre; Zweigenbaum, Pierre

    2003-01-01

    Question-answering (QA) systems, as have been presented and evaluated in several TREC conferences, are the next generation of search engines. They combine 'traditional' Information Retrieval (IR) with Natural Language Processing (NLP) and Knowledge Engineering techniques to provide shorter, more precise answers to natural language questions. We study here the feasibility of such a system for French in the health care domain. In this purpose, we collected a corpus of student questions in oral surgery. We examined two enabling conditions: on the IR side, how to select the right keywords in a question to identify relevant material on the Web for answering this question, a prerequisite for success; and on the NLP side, whether the contents of the questions fit the conceptual model of an existing QA prototype, a favorable condition for rapid implementation. A manual Web search enabled us to devise automatable principles for building IR queries for these questions. Besides, we could design a semantic model, using UMLS Semantic Network relations, which is consistent with our prototype and covers 90% of the questions. However, the high specialization of the domain and the clinical orientation of the questions, joined with the more limited resources online in the French language, may restrain the quantity of Web material available for answering these questions.

The meeting served as a forum for the exchange of information and discussion of PCB management issues. This document has been prepared as one of several guidance documents developed by the Department of Energy Office of Environmental Policy and Assistance (EH-41) (formerly the Office of Environmental Guidance, EH-23) to assist DOE elements in their PCB management programs. This document is organized into three parts: (1) an introduction describing the conception and development of this document, (2) a summary of Dr. Smith`s presentation, and (3) the question and answer session.

  10. Internationally educated workers jeopardy: answers and questions.

    PubMed

    Deber, Raisa

    2010-01-01

    Selecting policies for integrating internationally educated healthcare professionals (IEHPs) into the healthcare workforce depends on how the underlying policy questions are defined and how the resulting trade-offs are managed. Baumann, Blythe and Ross give excellent answers to the question of how to use IEHPs to alleviate health human resources shortages while ensuring quality; this can be linked to the questions of how many providers are "needed" by the system, as well as to how they are paid, who assumes the risks of oversupply and under-supply and whether data are available to track the workforce. But the questions could also be framed as fairness to the IEHPs themselves, fairness to the countries these providers come from or even as ensuring intergovernmental coordination within Canada, where decisions about immigration are not always aligned with decisions about training and certification. Boom-bust cycles have occurred before, and proven both counterproductive and wasteful. Particularly when there are no obviously correct answers, wisdom and balance by policy makers in framing the questions is essential. PMID:20523136

  18. Model answers to lipid membrane questions.

    PubMed

    Mouritsen, Ole G

    2011-09-01

    Ever since it was discovered that biological membranes have a core of a bimolecular sheet of lipid molecules, lipid bilayers have been a model laboratory for investigating physicochemical and functional properties of biological membranes. Experimental and theoretical models help the experimental scientist to plan experiments and interpret data. Theoretical models are the theoretical scientist's preferred toys to make contact between membrane theory and experiments. Most importantly, models serve to shape our intuition about which membrane questions are the more fundamental and relevant ones to pursue. Here we review some membrane models for lipid self-assembly, monolayers, bilayers, liposomes, and lipid-protein interactions and illustrate how such models can help answering questions in modern lipid cell biology.

    There have been 2, and possibly 3, major questions for primary aldosteronism (PA) answered at least in principle over the past 5 years. The first is that of somatic mutations underlying the majority of aldosterone producing adenomas. The second is the extension of our knowledge of the genetics of familial hypertension, and the third the role of renal intercalated cells in sodium homeostasis. New questions for the next 5 years include a single accepted confirmatory/exclusion test; standardisation of assays and cut-offs; alternatives to universal adrenal venous sampling; reclassification of 'low renin hypertension'; recognition of the extent of 'occult' PA; inclusion of low-dose mineralocorticoid receptor antagonist in first-line therapy for hypertension; and finally, possible resolution of the aldosterone/inappropriate sodium status enigma at the heart of the cardiovascular damage in PA.

  6. Does Anyone Know the Answer to that Question? Individual Differences in Judging Answerability

    PubMed Central

    Karlsson, Bodil S. A.; Allwood, Carl Martin; Buratti, Sandra

    2016-01-01

    Occasionally people may attempt to judge whether a question can be answered today, or if not, if it can be answered in the future. For example, a person may consider whether enough is known about the dangers of living close to a nuclear plant, or to a major electricity cable, for them to be willing to do so, and state-authorities may consider whether questions about the dangers of new technologies have been answered, or in a reasonable future can be, for them to be willing to invest money in research aiming develop such technologies. A total of 476 participants, for each of 22 knowledge questions, either judged whether it was answerable today (current answerability), or judged when it could be answered (future answerability). The knowledge questions varied with respect to the expected consensus concerning their answerability: consensus questions (high expected consensus), non-consensus questions (lower expected consensus), and illusion questions (formulated to appear answerable, but with crucial information absent). The questions’ judged answerability level on the two scales was highly correlated. For both scales, consensus questions were rated more answerable than the non-consensus questions, with illusion questions falling in-between. The result for the illusion questions indicates that a feeling of answerability can be created even when it is unlikely that somebody can come up with an answer. The results also showed that individual difference variables influenced the answerability judgments. Higher levels of belief in certainty of knowledge, mankind’s knowledge, and mankind’s efficacy were related to judging the non-consensus questions as more answerable. Participants rating the illusion questions as answerable rated the other answerability questions as more, or equally, answerable compared to the other participants and showed tendencies to prefer a combination of more epistemic default processing and less intellectual processing.

  7. Answering Physicians' Clinical Questions: Obstacles and Potential Solutions

    PubMed Central

    Ely, John W.; Osheroff, Jerome A.; Chambliss, M. Lee; Ebell, Mark H.; Rosenbaum, Marcy E.

    2005-01-01

    Objective: To identify the most frequent obstacles preventing physicians from answering their patient-care questions and the most requested improvements to clinical information resources. Design: Qualitative analysis of questions asked by 48 randomly selected generalist physicians during ambulatory care. Measurements: Frequency of reported obstacles to answering patient-care questions and recommendations from physicians for improving clinical information resources. Results: The physicians asked 1,062 questions but pursued answers to only 585 (55%). The most commonly reported obstacle to the pursuit of an answer was the physician's doubt that an answer existed (52 questions, 11%). Among pursued questions, the most common obstacle was the failure of the selected resource to provide an answer (153 questions, 26%). During audiotaped interviews, physicians made 80 recommendations for improving clinical information resources. For example, they requested comprehensive resources that answer questions likely to occur in practice with emphasis on treatment and bottom-line advice. They asked for help in locating information quickly by using lists, tables, bolded subheadings, and algorithms and by avoiding lengthy, uninterrupted prose. Conclusion: Physicians do not seek answers to many of their questions, often suspecting a lack of usable information. When they do seek answers, they often cannot find the information they need. Clinical resource developers could use the recommendations made by practicing physicians to provide resources that are more useful for answering clinical questions. PMID:15561792

    2015-01-01

    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. PMID:24960233

  11. How Online Crowds Influence the Way Individual Consumers Answer Health Questions

    PubMed Central

    Lau, A.Y.S.; Kwok, T.M.Y.; Coiera, E.

    2011-01-01

    Objective To investigate whether strength of social feedback, i.e. other people who concur (or do not concur) with one’s own answer to a question, influences the way one answers health questions. Methods Online prospective study. Two hundred and twenty-seven undergraduate students were recruited to use an online search engine to answer six health questions. Subjects recorded their pre- and post-search answers to each question and their level of confidence in these answers. After answering each question post-search, subjects were presented with a summary of post-search answers provided by previous subjects and were asked to answer the question again. Results There was a statistically significant relationship between the absolute number of others with a different answer (the crowd’s opinion volume) and the likelihood of an individual changing an answer (P<0.001). For most questions, no subjects changed their answer until the first 10–35 subjects completed the study. Subjects’ likelihood of changing answer increased as the percentage of others with a different answer (the crowd’s opinion density) increased (P=0.047). Overall, 98.3% of subjects did not change their answer when it concurred with the majority (i.e. >50%) of subjects, and that 25.7% of subjects changed their answer to the majority response when it did not concur with the majority. When subjects had a post-search answer that did not concur with the majority, they were 24% more likely to change answer than those with answers that concurred (P<0.001). Conclusion This study provides empirical evidence that crowd influence, in the form of online social feedback, affects the way consumers answer health questions. PMID:23616869

    2007-01-01

    Objective To describe the characteristics of unanswered clinical questions and propose interventions that could improve the chance of finding answers. Design In a previous study, investigators observed primary care physicians in their offices and recorded questions that arose during patient care. Questions that were pursued by the physician, but remained unanswered, were grouped into generic types. In the present study, investigators attempted to answer these questions and developed recommendations aimed at improving the success rate of finding answers. Measurements Frequency of unanswered question types and recommendations to increase the chance of finding answers. Results In an earlier study, 48 physicians asked 1062 questions during 192 half-day office observations. Physicians could not find answers to 237 (41%) of the 585 questions they pursued. The present study grouped the unanswered questions into 19 generic types. Three types accounted for 128 (54%) of the unanswered questions: (1) “Undiagnosed finding” questions asked about the management of abnormal clinical findings, such as symptoms, signs, and test results (What is the approach to finding X?); (2) “Conditional” questions contained qualifying conditions that were appended to otherwise simple questions (What is the management of X, given Y? where “given Y” is the qualifying condition that makes the question difficult.); and (3) “Compound” questions asked about the association between two highly specific elements (Can X cause Y?). The study identified strategies to improve clinical information retrieval, listed below. Conclusion To improve the chance of finding answers, physicians should change their search strategies by rephrasing their questions and searching more clinically oriented resources. Authors of clinical information resources should anticipate questions that may arise in practice, and clinical information systems should provide clearer and more explicit answers. PMID:17460122

    1997-08-01

    The pediatric health care provider is often faced with myriad decisions related to the use of infant formula. This article compares human milk to cow's milk. It addresses the composition, classification, and use of some of the most common infant formulas manufactured for use with the term infant in the outpatient setting. Common clinical situations are discussed, including the role for low-iron, goat's milk, and follow-up formulas, and formula use for the infant with diarrhea, colic, and atopic disease. The article highlights the poor quality of research and the lack of definitive answers available to the clinician when managing the infant with atopic disease. It concludes with a review of practical aspects of infant formula feeding for use in client education and management, including guidelines for formula preparation, calculating necessary formula intake, frequency, and quantity of infant feedings, and provisions of the WIC program.

    Tracking performance through reporting is a basic obligation for responsible lab management. But creative, visionary leadership requires that lab leaders ask better questions, reach better conclusions, and transform those conclusions into action to achieve better results. The clinical lab has always had the breadth of data to contribute to that process. With analytics, lab leaders now have the depth and control to effect positive change as well. PMID:26299148

    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.

    2014-01-01

    With the blooming of Web 2.0, Community Question Answering (CQA) services such as Yahoo! Answers (http://answers.yahoo.com), WikiAnswer (http://wiki.answers.com), and Baidu Zhidao (http://zhidao.baidu.com), etc., have emerged as alternatives for knowledge and information acquisition. Over time, a large number of question and answer (Q&A) pairs with high quality devoted by human intelligence have been accumulated as a comprehensive knowledge base. Unlike the search engines, which return long lists of results, searching in the CQA services can obtain the correct answers to the question queries by automatically finding similar questions that have already been answered by other users. Hence, it greatly improves the efficiency of the online information retrieval. However, given a question query, finding the similar and well-answered questions is a non-trivial task. The main challenge is the word mismatch between question query (query) and candidate question for retrieval (question). To investigate this problem, in this study, we capture the word semantic similarity between query and question by introducing the topic modeling approach. We then propose an unsupervised machine-learning approach to finding similar questions on CQA Q&A archives. The experimental results show that our proposed approach significantly outperforms the state-of-the-art methods. PMID:24595052

  10. Medical Marijuana: More Questions than Answers

    PubMed Central

    Hill, Kevin P.

    2014-01-01

    With 23 states and the District of Columbia having enacted medical marijuana laws as of August 2014, it is important that psychiatrists be able to address questions about medical marijuana from patients, families, and other health care professionals. The author discusses the limited medical literature on synthetic cannabinoids and medical marijuana. The synthetic cannabinoids dronabinol and nabilone are approved by the United States Food and Drug Administration for nausea and vomiting associated with cancer chemotherapy and appetite stimulation in patients with wasting diseases such as acquired immunodeficiency syndrome (AIDS). Results of clinical trials of these agents for other conditions have varied widely thus far. In addition, few data are available on the use of the marijuana plant as a medical treatment. The author concludes that there is a clear need for additional research on possible medical uses of cannabinoids. He notes that discussions with prospective medical marijuana patients should emphasize the importance of communication among all parties due to the possible side effects of treatment with marijuana and its potential to interact with other medications the patient may be taking. Facilitating a thorough substance abuse consultation is one of most positive ways that psychiatrists, especially addiction psychiatrists, can make an impact as medical marijuana becomes increasingly common. A careful review of the prospective medical marijuana user's substance use history, co-occurring medical and psychiatric conditions, family history, and psychosocial stressors is essential in evaluating the potential risks of medical marijuana for these patients. The author concludes that psychiatrists can have a significant impact by increasing the likelihood that medical marijuana will be used in a safe and responsible way. PMID:25226202

    2000-01-01

    Objectives: Despite the growing use of online databases by clinicians, there has been very little research documenting how effectively they are used. This study assessed the ability of medical and nurse-practitioner students to answer clinical questions using an information retrieval system. It also attempted to identify the demographic, experience, cognitive, personality, search mechanics, and user-satisfaction factors associated with successful use of a retrieval system. Methods: Twenty-nine students completed questionnaires of clinical and computer experience as well as tests of cognitive abilities and personality type. They were then administered three clinical questions to answer in a medical library setting using the MEDLINE database and electronic and print full-text resources. Results: Medical students were able to answer more questions correctly than nurse-practitioner students before and after searching, but both had comparable improvements in the number of correct questions before and after searching. Successful ability to answer questions was also associated with having experience in literature searching and higher standardized test-score percentiles. Conclusions: Medical and nurse-practitioner students obtained comparable benefits in the ability to answer clinical questions from use of the information retrieval system. Future research must examine strategies that improve successful search and retrieval of clinical questions posed by clinicians in practice. PMID:11055299

    2013-01-01

    OBJECTIVE: To evaluate the attitudes of adolescents toward communicating with their doctor about different aspects of their sexuality. METHODS: The present descriptive survey was conducted with the participation of teenagers from four high schools in Sherbrooke, Quebec. In each school, the students of two grade 8 classes (≀14 years of age) and two grade 10 classes (≄15 years of age) anonymously completed a self-administered questionnaire. Permission from the school board and parental consent for every participant was obtained. RESULTS: A total of 387 adolescents completed the self-administered questionnaire. The response rate for the study was 98%. Only 27% of the respondents remembered being questioned by their doctor about sexuality, and 17% of the respondents had already brought up the topic of sexuality themselves with their doctor. More than one-half (57%) of the adolescents reported they would be moderately comfortable to totally comfortable discussing sexuality with their doctor if they felt the need to. Overall, when asked to evaluate their degree of comfort if questioned on specific questions about their sexuality, 73.8% to 99.5% believed they would be moderately to totally comfortable responding. Nevertheless, there was a statistically significant difference between age groups, with the older age group being more comfortable than the younger age group (P<0.001). There was no difference between the level of comfort among boys and girls answering the same questions. Respondents believed that their treating physician should discuss sexuality with them (73.8%) and, in the majority of cases (78%), that he/she should initiate the conversation. CONCLUSION: Regardless of age or sex, teenagers considered themselves to be at ease discussing sexuality with their doctor and found it an important topic best brought up by their practitioner.

    The Office of Energy Research, US DOE is evaluating the concept of obtaining significant amounts of electrical energy from space through the Satellite Power System Project Office (SPS PO) formed for that purpose. The SPS PO prepared and is implementing a Concept Development and Evaluation Program plan. The CDEP runs roughly three years (from July 1977 through July 1980) and consists of four primary elements: (1) Systems Definition, (2) Environmental Assessment, (3) Societal Assessment, and (4) Comparative Assessment. One facet of the Societal Assessment is an investigation of public concerns. To further this investigation, a public outreach experiment was initiated to determine the initial response of three selected interest groups to the SPS, both qualitatively and quantititavely, and to gain some experience for use in future public participation activities. Three groups were contacted and agreed to participate in the experiment. They were: the Citizens Energy Project (CEP), the Forum for the Advancement of Students in Science and Technology (FASST), and the L-5 Society (L-5). They each agreed to condense twenty final SPS reports into approximately four pages each, have them typeset, printed and distributed to 3,000 of their constituents for their review, together with a request that they respond to the parent organization regarding the information presented. All responses were summarized and provided to Planning Research Corporation who then solicited the answers from the SPS PO investigator most directly concerned.The questions and answers are presented and will be distributed by the three groups to the individual respondents. Each of the three groups is also preparing a report to the Project Office detailing their work and results. These, together with other responses and studies will be used to more effectively involve the public in the SPS Participatory Technology Process.

  17. Improving comprehension of science content: Generating self-explanation questions and creating explanatory answers

    NASA Astrophysics Data System (ADS)

    Clelland, Peggie L.

    The emphasis on learning in content area classrooms is heavily dependent on remembering facts and memorizing definitions. Because of this, students often achieve shallow levels of comprehension and are deficient in the skills necessary to achieve deeper comprehension. Teaching students to generate self-explanation questions and answers related to teacher lectures and from reading text can improve comprehension. Students who attempt to explain what the content means understand it better and at a deeper level. The purpose of this study was to examine the effectiveness of teaching students to ask self-explanation questions as a means for improving comprehension. Eighth-grade students from three heterogeneous science classrooms participated in one of the treatment or comparison groups. The first treatment group was taught to generate self-explanation questions while the second treatment group was taught to generate self-explanation questions and to create explanatory answers using a rubric. The comparison group received their regular science instruction. Self-explanation question/answer participants scored significantly higher than the regular instruction group more often than the self-explanation question only group, on memory and essay measures. Analyses were performed with MANCOVA on all three groups' scores as a set. ANCOVA was used to determine if differences existed between groups on each of the dependent variables, and Bonferonni's post-hoc contrasts were used to determine where differences existed among treatment and comparison groups. Results revealed that students who were taught to generate self-explanation questions and/or to create explanatory answers outperformed the regular instruction students on some of the memory and essay measures. Additionally, teaching students a self-explanation strategy resulted in improved ability to respond to essay questions two weeks following the conclusion of the study compared to students who received regular instruction.

    Recent technological advances have given rise to an information-gathering tool unparalleled by any in human history-the Internet. Understanding how access to such a powerful informational tool influences how we think represents an important question for psychological science. In the present investigation we examined the impact of access to the Internet on the metacognitive processes that govern our decisions about what we "know" and "don't know." Results demonstrated that access to the Internet influenced individuals' willingness to volunteer answers, which led to fewer correct answers overall but greater accuracy when an answer was offered. Critically, access to the Internet also influenced feeling-of-knowing, and this accounted for some (but not all) of the effect on willingness to volunteer answers. These findings demonstrate that access to the Internet can influence metacognitive processes, and contribute novel insights into the operation of the transactive memory system formed by people and the Internet.

  20. Epistemic Questions and Answers for Software System Safety

    NASA Technical Reports Server (NTRS)

    Holloway, C. M.; Johnson, Chris W.

    2010-01-01

    System safety is primarily concerned with epistemic questions, that is, questions concerning knowledge and the degree of confidence that can be placed in that knowledge. For systems with which human experience is long, such as roads, bridges, and mechanical devices, knowledge about what is required to make the systems safe is deep and detailed. High confidence can be placed in the validity of that knowledge. For other systems, however, with which human experience is comparatively short, such as those that rely in part or in whole on software, knowledge about what is required to ensure safety tends to be shallow and general. The confidence that can be placed in the validity of that knowledge is consequently low. In a previous paper, we enumerated a collection of foundational epistemic questions concerning software system safety. In this paper, we review and refine the questions, discuss some difficulties that attend to answering the questions today, and speculate on possible research to improve the situation.

  1. Venus Express: Answered and unanswered questions on Venus (Invited)

    NASA Astrophysics Data System (ADS)

    Svedhem, H.; Titov, D.

    2013-12-01

    After having orbited our sister planet for more than seven Earth years Venus Express has collected a very large data set allowing a great number of fundamental scientific questions to be addressed and answered. Most of the questions included in the mission's science requirement, as formulated in the mission proposal, have been answered. These include topics in atmospheric dynamics, structure and chemistry, clouds and hazes, surface and interior, radiation balance and greenhouse, induced magnetosphere and plasma environment, and planetary evolution. Solid results have been achieved in all these fields but with some weakness in the radiation balance measurements, mostly due to the early loss of the planetary Fourier spectrometer providing data at the mid infrared wavelengths. Naturally, due to the limited scope and budget of the Venus Express mission a number of important questions had to be left unaddressed and to be taken up by future missions. This talk will summarise the major results of Venus Express and discuss a number of questions where additional data will be needed in order to provide answers. A wish list for future missions will be provided.

    2005-01-01

    Currently, there is a discrepancy between clinical trials designed to assess the efficacy and safety of a new medication under investigation and the real-life questions that need to be addressed regarding the clinical use of the medication by patients, healthcare professionals and society. The data necessary to obtain regulatory approval may be of limited relevance to policy makers when calculating economic parameters such as value for money or cost effectiveness. 'Real-world' studies examine questions relevant to health policy and reimbursement. There are many different forms of clinical trials, but in designing trials incorporating realistic budget impact estimates the important issue is to ensure we are asking a sensible question and attempting to answer it with an appropriate experimental design. As an example, a real-world trial currently underway that examines scenarios of introducing inhaled insulin into clinical practice is described. PMID:16097837

    Objective Clinical questions are often long and complex and take many forms. We have built a clinical question answering system named AskHERMES to perform robust semantic analysis on complex clinical questions and output question-focused extractive summaries as answers. Design This paper describes the system architecture and a preliminary evaluation of AskHERMES, which implements innovative approaches in question analysis, summarization, and answer presentation. Five types of resources were indexed in this system: MEDLINE abstracts, PubMed Central full-text articles, eMedicine documents, clinical guidelines and Wikipedia articles. Measurement We compared the AskHERMES system with Google (Google and Google Scholar) and UpToDate and asked physicians to score the three systems by ease of use, quality of answer, time spent, and overall performance. Results AskHERMES allows physicians to enter a question in a natural way with minimal query formulation and allows physicians to efficiently navigate among all the answer sentences to quickly meet their information needs. In contrast, physicians need to formulate queries to search for information in Google and UpToDate. The development of the AskHERMES system is still at an early stage, and the knowledge resource is limited compared with Google or UpToDate. Nevertheless, the evaluation results show that AskHERMES’ performance is comparable to the other systems. In particular, when answering complex clinical questions, it demonstrates the potential to outperform both Google and UpToDate systems. Conclusions AskHERMES, available at http://www.AskHERMES.org, has the potential to help physicians practice evidence-based medicine and improve the quality of patient care. PMID:21256977

    1989-01-01

    We conducted an investigation to evaluate the effects of a training strategy for teaching autistic students generalized responses to three forms of wh--questions (what, how, and why). Students were taught, using modeling and reinforcement procedures, to answer questions with magazine pictures as the referents. Each question form was divided into two or more subcomponents reflective of common social usage and was taught within the context of a modified multiple probe design across subcomponents. Following acquisition of each subcomponent, generalization to natural context and storybook questions was assessed; additional probes were conducted to assess responding over time and whether acquisition of responses to questions promoted question-asking skills. Results showed that the picture training procedure was effective in teaching a generalized response to questions for which the relevant cue was visible, whereas specific generalization programming was required for situations in which the relevant cue was not visible. All acquired responses were durable over time. PMID:2745239

    Volatile anesthetic agents have been used for decades in the peri-operative setting. Data from the past 15 years have shown that pre-injury administration of volatile anesthetic can decrease the impact of ischemia-reperfusion injury on the heart, brain, and kidney. Recent data demonstrated that volatile agents administered shortly after injury can decrease the ischemia-reperfusion injury. Several questions need to be answered to optimize this therapeutic target, but this is a promising era of secondary injury mitigation. PMID:23176148

  12. Automating the search for answers to open questions

    2000-05-31

    This article provides evidence for the arrival of automated reasoning. Indeed, one of its primary goals of the early 1960s has been reached: The use of an automated reasoning program frequently leads to significant contributions to mathematics and to logic. In addition, although not clearly an original objective, the use of such a program now plays an important role for chip design and for program verification. That importance can be sharply increased; indeed, in this article the authors discuss the possible value of automated reasoning to finding better designs of chips, circuits, and computer code. They also provide insight into the mechanisms--in particular, strategy--that have led to numerous successes. To complement the evidence they present and to encourage further research, the offer challenges and open questions for consideration. They include a glimpse of the future and some commentary on the possibly unexpected benefits of automating the search for answers to open questions.

  13. PrimeAnswers: A practical interface for answering primary care questions.

    PubMed

    Ketchell, Debra S; St Anna, Leilani; Kauff, David; Gaster, Barak; Timberlake, Diane

    2005-01-01

    This paper describes an institutional approach taken to build a primary care reference portal. The objective for the site is to make access to and use of clinical reference faster and easier and to facilitate the use of evidence-based answers in daily practice. Reference objects were selected and metadata applied to a core set of sources. Metadata were used to search, sort, and filter results and to define deep-linked queries and structure the interface. User feedback resulted in an expansion in the scope of reference objects to meet the broad spectrum of information needs, including patient handouts and interactive risk management tools. RESULTS of a user satisfaction survey suggest that a simple interface to customized content makes it faster and easier for primary care clinicians to find information during the clinic day and to improve care to their patients. The PrimeAnswers portal is a first step in creating a fast search of a customized set of reference objects to match a clinician's patient care questions in the clinic. The next step is developing methods to solve the problem of matching a clinician's question to a specific answer through precise retrieval from reference sources; however, lack of internal structure and Web service standards in most clinical reference sources is an unresolved problem.

  5. Answering questions about consciousness by modeling perception as covert behavior.

    PubMed

    Markkula, Gustav

    2015-01-01

    Two main open questions in current consciousness research concern (i) the neural correlates of consciousness (NCC) and (ii) the relationship between neural activity and first-person, subjective experience. Here, possible answers are sketched for both of these, by means of a model-based analysis of what is required for one to admit having a conscious experience. To this end, a model is proposed that allows reasoning, albeit necessarily in a simplistic manner, about all of the so called "easy problems" of consciousness, from discrimination of stimuli to control of behavior and language. First, it is argued that current neuroscientific knowledge supports the view of perception and action selection as two examples of the same basic phenomenon, such that one can meaningfully refer to neuronal activations involved in perception as covert behavior. Building on existing neuroscientific and psychological models, a narrative behavior model is proposed, outlining how the brain selects covert (and sometimes overt) behaviors to construct a complex, multi-level narrative about what it is like to be the individual in question. It is hypothesized that we tend to admit a conscious experience of X if, at the time of judging consciousness, we find ourselves acceptably capable of performing narrative behavior describing X. It is argued that the proposed account reconciles seemingly conflicting empirical results, previously presented as evidence for competing theories of consciousness, and suggests that well-defined, experiment-independent NCCs are unlikely to exist. Finally, an analysis is made of what the modeled narrative behavior machinery is and is not capable of. It is discussed how an organism endowed with such a machinery could, from its first-person perspective, come to adopt notions such as "subjective experience," and of there being "hard problems," and "explanatory gaps" to be addressed in order to understand consciousness.

  7. NUFACT11 Round Table Discussion — Questions & Answers

    NASA Astrophysics Data System (ADS)

    Blondel, A.; Efthymiopoulos, I.; participants, NUFACT11

    2013-02-01

    This presents the response to questions formulated by a round table discussion panel to the NUFACT11 participants. The main points made were as follows. Neutrino mass is physics beyond the Standard Model; it presents a very deep puzzle to solve, with the answers to several fundamental questions as potential reward. Precision measurement of oscillation parameters is one essential way to access information needed to solve this puzzle and there is a relatively clear (but not easy) way forward. Large Ξ13 makes the appearance signals larger, but does not allow to relax the requirements on high beam intensity and large detector masses; it creates a difficult challenge on systematic errors, which will require dedicated ancillary experiments. Of particular interest is a low intensity muon storage ring for required cross-section measurements. There exist already extended bottom-up international collaboration in both physics and R&D experiments. All three main regions have plans for upgraded super-beams and associated detectors, with a variety of (mostly) complementary baselines, proceeding in an incremental way. The ultimate precision and verification of the neutrino mixing picture requires new types of neutrino beams based on storage rings. For low energy neutrinos, the beta-beam is a possible (but substantial) intermediate step. The Neutrino Factory offers the best precision and best sensitivity to deviations from the standard picture. Coordinated international R&D is pursued. International collaboration at the top level would be beneficial in acknowledging the process, so as make sure that intermediate steps are effectively building up in complementary fashion towards the ultimate goals.

  8. Answering Scientific Questions Using an Artistic Framework: A Personal Perspective

    NASA Astrophysics Data System (ADS)

    Little, S. F. B.

    2014-12-01

    Being multidisciplinary, while admired, is not viewed as a goal of education. Instead, extreme specialization is emphasized. One seeks to attain mastery of a given subject, but at what cost? Even those fields viewed as "interdisciplinary" are often quite narrow in scope, only permitting the most closely related subjects to coalesce. The arts however, are by nature both inter- and multi-disciplinary. They attempt to research, analyze, and reflect upon broader questions, often employing techniques garnered from far-flung fields in order to do so. It is an unfortunate dilemma then that the artist should seem so separate from the scientist, as it seems that both are engaged in a sort of hypothesis testing. Perhaps this division is a remnant of the antiquated left- and right-brained dichotomy, which clearly separated the two groups: Science and Art, Left and Right. In this way, the artist was branded as Science's "other," despite the inherent sameness of their processes. This "otherness" has been carried forward to the present, where artists are often viewed as simply craftspeople -object makers- and the concept of the "artistic problem" is rarely considered. As someone possessing degrees in both Fine Art and Hydrology, the author attempts to explain the connection between the two subjects, and the manner in which they compliment and enlighten each other in her own research. She hypothesizes that in addition to this "otherness," it is the multi-dimensional mode of thinking and dealing with problems that sets the artist apart. But this is a dynamic trait, and as such, it should be considered that by approaching scientific endeavors as artistic problems, the researcher could be permitted a broader framework in which to answer a given scientific question.

  9. Structural answers and persistent questions about how nicotinic receptors work

    PubMed Central

    Wells, Gregg B.

    2008-01-01

    The electron diffraction structure of nicotinic acetylcholine receptor (nAChR) from Torpedo marmorata and the X-ray crystallographic structure of acetylcholine binding protein (AChBP) are providing new answers to persistent questions about how nAChRs function as biophysical machines and as participants in cellular and systems physiology. New high-resolution information about nAChR structures might come from advances in crystallography and NMR, from extracellular domain nAChRs as high fidelity models, and from prokaryotic nicotinoid proteins. At the level of biophysics, structures of different nAChRs with different pharmacological profiles and kinetics will help describe how agonists and antagonists bind to orthosteric binding sites, how allosteric modulators affect function by binding outside these sites, how nAChRs control ion flow, and how large cytoplasmic domains affect function. At the level of cellular and systems physiology, structures of nAChRs will help characterize interactions with other cellular components, including lipids and trafficking and signaling proteins, and contribute to understanding the roles of nAChRs in addiction, neurodegeneration, and mental illness. Understanding nAChRs at an atomic level will be important for designing interventions for these pathologies. PMID:18508600

  10. TrustQ: a category reputation based question and answer system

    NASA Astrophysics Data System (ADS)

    Lin, Yuhua; Shen, Haiying

    2014-06-01

    Question and Answering (Q/A) systems aggregate the collected intelligence of all users to provide satisfying answers for questions. A well-developed Q/A system should provide high question response rate, low response delay and good answer quality. Previous works use reputation systems to achieve the goals. However, these reputation systems evaluate a user with an overall rating for all questions the user has answered regardless of the question categories, thus the reputation score cannot accurately reflect the user's ability to answer a question in a specific category. In this paper, we propose TtustQ, a category reputation based Q/A System. TtustQ evaluates users' willingness and capability to answer questions in different categories. Considering a user has different willingness to answer questions from different users, TtustQ lets each node evaluate the reputation of other nodes answering its own questions. User a calculates user b's final reputation by considering both user a's direct rating and the indirect ratings on user b from other nodes. The reputation values facilitate forwarding a question to potential answerers, which improves the question response rate, response delay and answer quality. Our trace-driven simulation on PeerSim demonstrates the effectiveness of TtustQ in providing good user experience in terms of response rate and latency, and the answer quality.

  12. 150 Student Questions on Solar Physics

    NASA Astrophysics Data System (ADS)

    Lopez, R. E.; Gross, N. A.; Knipp, D. J.

    2010-12-01

    The Center for Integrated Space Weather Modeling (CISM) holds a two-week Space Weather Summer School for introductory graduate students and space weather professionals to gain a system level understanding of the space environment and the effects of space weather. A typical day in the summer school consists of three morning lectures followed by an afternoon lab session. After the morning lectures, the participants are each asked to submit a question about the mornings topics on a question card. The lecturers then take the time to answer these questions prior to afternoon sessions. In the last 5 years over 1000 such question cards have been collected and cataloged. Despite detailed lectures by experts similar questions appear every year. We have analyzed over 150 questions related to the introductory lectures on solar physics and solar activity. Questions content was categorized using the AGU Index, and question sophistication was categorized using Bloom’s Taxonomy of Educational Objectives. Specific analysis results along with lists of questions will be presented. We hope that these results can be used to improve the lecture and classroom content and allow students to move beyond low level education objectives and ask more sophisticated questions.

  20. Reducing Our Ignorance: Finding Answers to Certain Epistemic Questions for Software Systems

    NASA Technical Reports Server (NTRS)

    Holloway, C. Michael; Johnson, Christopher W.

    2011-01-01

    In previous papers, we asserted that software system safety is primarily concerned with epistemic questions, that is, questions concerning knowledge and the degree of confidence that can be placed in that knowledge. We also enumerated a set of 21 foundational epistemic questions, discussed some of the difficulties that exist in answering these questions adequately today, and speculated briefly on possible research that may provide improved confidence in the sufficiency of answers in the future. This paper focuses on three of the foundational questions. For each of these questions, current answers are discussed and potential research is proposed to help increase the justifiable level of confidence.

  12. Can Emergency Medicine Residents Reliably Use the Internet to Answer Clinical Questions?

    PubMed Central

    Krause, Richard; Moscati, Ronald; Halpern, Shravanti; Schwartz, Diane G; Abbas, June

    2011-01-01

    Introduction The study objective was to determine the accuracy of answers to clinical questions by emergency medicine (EM) residents conducting Internet searches by using Google. Emergency physicians commonly turn to outside resources to answer clinical questions that arise in the emergency department (ED). Internet access in the ED has supplanted textbooks for references because it is perceived as being more up to date. Although Google is the most widely used general Internet search engine, it is not medically oriented and merely provides links to other sources. Users must judge the reliability of the information obtained on the links. We frequently observed EM faculty and residents using Google rather than medicine-specific databases to seek answers to clinical questions. Methods Two EM faculties developed a clinically oriented test for residents to take without the use of any outside aid. They were instructed to answer each question only if they were confident enough of their answer to implement it in a patient-care situation. Questions marked as unsure or answered incorrectly were used to construct a second test for each subject. On the second test, they were instructed to use Google as a resource to find links that contained answers. Results Thirty-three residents participated. The means for the initial test were 32% correct, 28% incorrect, and 40% unsure. On the Google test, the mean for correct answers was 59%; 33% of answers were incorrect and 8% were unsure. Conclusion EM residents' ability to answer clinical questions correctly by using Web sites from Google searches was poor. More concerning was that unsure answers decreased, whereas incorrect answers increased. The Internet appears to have given the residents a false sense of security in their answers. Innovations, such as Internet access in the ED, should be studied carefully before being accepted as reliable tools for teaching clinical decision making. PMID:22224135

    The present purpose was to examine racial differences in response rate and serious behavioral suicide risk based on the national Youth Risk Behavior Surveillance Survey (YRBS). Data from 15,245 adolescents (YRBS, 2011) were included. Survey items pertaining to making suicidal plans and attempting suicide were included. Significant differences in responding and content emerged, especially with regard to suicide attempts. Racial minority adolescents are at elevated risk for serious suicidal behaviors and are more likely to omit items pertaining to suicide attempts. African American adolescents rarely reported having attempted suicide, but they also frequently failed to respond to that question. PMID:26083790

  14. Postdischarge nutrition of preterm infants: more questions than answers.

    PubMed

    Cooke, Richard J

    2007-01-01

    Postnatal growth retardation is inevitable in preterm infants, the more immature the infant the greater the degree of postnatal growth retardation at hospital discharge. After hospital discharge, several studies have shown that growth is poorer in preterm infants fed a standard term formula than those fed a nutrient-enriched infant formula. This is not surprising because term formulas are designed to meet the requirements of the term infant, not the more rapidly growing preterm infant. After hospital discharge, breastfed infants do not grow as well as their formula-fed counterparts. Yet, there are no randomized controlled trials comparing growth in breastfed infants who did and did not receive nutrient supplementation. If mature human milk is designed to meet the needs of the term infant then breastfed preterm infants may also benefit from nutrient supplementation. Questions persist about nutritional support of preterm infants after discharge. What is the ideal composition of a postdischarge formula? Given the wide heterogeneity in nutritional status of preterm infants at hospital discharge and the difference in growth rates and composition between girls and boys, it is not clear that one formula can or will meet the nutritional needs of all infants. Studies in which infants were fed a nutrient-enriched formula to >/=6 months' corrected age show the most consistent advantage while those in which the nutrient-enriched formula was fed to

  15. Can undergraduate biology students learn to ask higher level questions?

    NASA Astrophysics Data System (ADS)

    Marbach-Ad, Gili; Sokolove, Phillip G.

    2000-10-01

    Our goals in this study were to explore the type of written questions students ask after reading one or more chapters from their textbook, and to investigate the ability of students to improve their questions during the course of a single semester. In order to classify student's questions we used a taxonomy that we have developed specifically for this purpose. Two comparable populations were examined: Undergraduate students in a large, introductory biology class who were taught in traditional lecture format, and students in a similar class who were taught in cooperative/active learning style. After the taxonomy was presented to the active learning class, more students were able to pose better, written questions. Their questions became more insightful, thoughtful, and content-related, and were not easily answered by consulting the textbook or another readily available source. The best questions could be recast as scientific research questions (i.e., hypotheses). In contrast, when the taxonomy was presented to students in the traditionally taught class, the quality of student-posed questions was largely unchanged. Various explanations for the difference in outcomes are discussed, and methods are suggested about how generally to encourage students' questions and to improve their question-asking skills regardless of overall teaching style.

  18. The 'Sentinel Node' Concept: More Questions Raised than Answers Provided?

    PubMed

    Schlag

    1998-01-01

    The prognosis of malignant disease is essentially determined by the metastatic potential of the primary tumor. In the past, scientific attention was chiefly directed to systemic metastasis. A multitude of biological and molecular tumor markers and mechanisms has been uncovered enabling a better contemporary understanding of the process of hematogenic metastasis. This is in contrast with our knowledge of the mechanisms and pathways of lymphatic tumor spread, which is rather limited. We do know, however, that adequate surgical clearance of the regional lymphatics improves treatment results of many tumors. How far this lymph node dissection is directly therapeutic is a source of controversy. While in some instances, a stage-adjusted survival benefit was demonstrated, this may very well be attributable at least in part to the phenomenon of stage migration (Will Rodgers phenomenon) through better staging. However, it is uncontested that an established diagnosis of regional lymphatic spread is prognostically significant and should influence the indication for additional therapy and eventually for an intensive follow-up. For many tumors, the indication for adjuvant chemotherapy depends on the nodal status. On the other hand, it is equally well known that aggressive lymphatic dissection increases perioperative morbidity and even mortality. Long-term sequellae from regional lymphatic dissection are common and the effect on the local, maybe even the systemic immunological response to the malignant disease, remains unclear. To incur such risk seems especially problematic in those patients without any lymphatic spread at the time of the pathologist's work-up. Thus, there is ongoing debate about the rationale, value, extent, advantage, or disadvantage of regional surgical lymph node dissection or even radiotherapy of the regional lymphatic drainage area for many different tumors. A considerable step forward could be made if there was any diagnostic modality enabling a reliable preoperative lymph node staging. However, there is none. General criteria like size, shape, structure, or texture in variable imaging modalities are unreliable. While it is still too early to definitely evaluate in this context new diagnostic modalities like PET, immunoscintigraphy, or contrast-enhanced MRI, the initial results do not provoke clear enthusiasm toward the development of a sensitive and specific staging tool with regard to the nodal status. Adequate specificity may be obtained by external or endoluminal ultrasound-guided fine needle biopsies. However, uncertainty arises from eventually unrepresentative tissue sampling. The sentinel lymphonodectomy technique may remedy the dilemma, enabling a risk-adapted, individual indication for regional lymphatic dissection. This concept, first introduced in 1977 by Cabanas into the treatment of penis carcinoma, is based on the evidence of orderly and predictable lymphatic drainage pathways. Tumor cell progression within the lymphatic system seems to follow a sequential pattern. Primary draining lymph nodes possess the structural and functional capability to retain and to fight tumor cells efficiently. The 'sentinel node' is defined as the first tumor draining filter, and, if uninvolved, should thus adequately predict the nodal status of the disease. Skip metastases beyond an uninvolved sentinel node are supposed to be a very rare event. The reliability of the 'Cabanas approach', however, was limited by its relatively poor localization technique, and therefore failed to gain widespread acceptance. Unfortunately, the significance of the concept was not fully appreciated at the time. It is to Morton's credit that the procedure was reinstituted in malignant melanoma through a dye injection technique at the primary tumor site. This led to a rapid development and refinement of intraoperative lymphatic mapping. One major step in this process was to use radiolabeled colloids in conjunction with gamma-camera imaging or gamma probe-guided detection of the sentinel node. At present, a multitude of studies are conducted in a variety of tumors and sites, aiming at further refinements of the technique or at clinical evaluation in comparison with established lympadenectomy. The results may well change many aspects of our operative strategy in the near future. However, assuming a technically optimized procedure, will this solve the underlying tumor biological and clinical problem with respect to the necessity and efficacy of a regional lymph node dissection in node-positive cases? This is not the case; moreover, there are additional questions raised and left unanswered so far. Without any doubt, the rate of unnecessary diagnostic lymph node dissections can be considerably reduced as soon as the sentinel node concept is sufficiently validated for general use outside clinical trials. This would be a clear step forward. It is undetermined, however, how far a cancer patient with a positive sentinel node-thus already proven lymphatic metastases-would still profit from a more or less extensive lymph node dissection. It might be sufficient to use the staging information obtained through the sentinel node's status alone to decide upon adjuvant therapies. A further aspect arises from the possibility for investigating this single and supposedly most representative lymph node in far more detail than it would be possible for the large number of nodes previously sampled in conventional lymphatic dissections. This more extensive work-up may include serial sectioning, immunological and molecular techniques to enhance the sensitivity for micrometastases detection. However, very little is known about the true prognostic significance of such conventionally occult micrometastases, and even less experience exists as to the value of adjuvant therapies in those cases. Thus, while the sentinel node procedure will probably enable a more precise though less invasive lymphatic staging of malignant disease, it raises a number of important questions, as well. The general principles of multimodal treatment will have to be redefined with regard to the new diagnostic tool, which will require extensive prospective and randomized testing before a safe and reliable advantage for the patients may be established.

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

    PubMed

    Gibson, Susan I

    2015-01-01

    A rising need for workers in science, technology, engineering and mathematics (STEM) fields has fueled interest in improving teaching within STEM disciplines. Numerous studies have demonstrated the benefits of active learning approaches on student learning outcomes. However, many of these studies have been conducted in experimental, rather than real-life class, settings. In addition, most of these studies have focused on in-class active learning exercises. This study tested the effects of answering questions outside of class on exam performance for General Biology students at the University of Minnesota. An online database of 1,020 multiple-choice questions covering material from the first half of the course was generated. Students in seven course sections (with an average of ∌265 students per section) were given unlimited access to the online study questions. These students made extensive use of the online questions, with students answering an average of 1,323 questions covering material from the half of the semester for which the questions were available. After students answered a set of questions, they were shown the correct answers for those questions. More specific feedback describing how to arrive at the correct answer was provided for the 73% of the questions for which the correct answers were not deemed to be self-explanatory. The extent to which access to the online study questions improved student learning outcomes was assessed by comparing the performance on exam questions of students in the seven course sections with access to the online study questions with the performance of students in course sections without access to the online study questions. Student performance was analyzed for a total of 89 different exams questions that were not included in the study questions, but that covered the same material covered by the study questions. Each of these 89 questions was used on one to five exams given to students in course sections that had access to the online study questions and on three to 77 exams given to students in sections that lacked such access. Data from over 1,800 students in sections with access to the online study questions show that those students scored a statistically significant average of 6.6% points higher on the exam questions analyzed than students in sections without access to the study questions. This difference was greater than the average amount necessary to raise students' exam grades by one grade (e.g., from a "B-" to a "B"). In addition, there was a higher correlation between number of questions answered and success on exam questions on material related to the study questions than between number of questions answered and success on exam questions on material unrelated to the study questions. The online study question system required substantial effort to set up, but required minimal effort to maintain and was effective in significantly raising average exam scores for even very large course sections.

  20. Are Wikipedia Resources Useful for Discovering Answers to List Questions within Web Snippets?

    NASA Astrophysics Data System (ADS)

    Figueroa, Alejandro

    This paper presents LiSnQA, a list question answering system that extracts answers to list queries from the short descriptions of web-sites returned by search engines, called web snippets. LiSnQA mines Wikipedia resources in order to obtain valuable information that assists in the extraction of these answers. The interesting facet of LiSnQA is, that in contrast to current systems, it does not account for lists in Wikipedia, but for its redirections, categories, sandboxes, and first definition sentences. Results show that these resources strengthen the answering process.

    Students in my first semester calculus based mechanics class are required to submit by email the answer to a conceptually oriented question by midnight the night before each class meeting. A distinct pre-class question is posted on the class web site for each class meeting. This question and its answer are addressed during class. At least one similar question appears on each exam as well. The students were surveyed regarding improvements to their study habits and increases in their learning that they attribute to these pre-class questions. Since I won’t be giving this survey until December, the results will be as informative for me as I hope they will be for you!

  5. A cognitive evaluation of four online search engines for answering definitional questions posed by physicians.

    PubMed

    Yu, Hong; Kaufman, David

    2007-01-01

    The Internet is having a profound impact on physicians' medical decision making. One recent survey of 277 physicians showed that 72% of physicians regularly used the Internet to research medical information and 51% admitted that information from web sites influenced their clinical decisions. This paper describes the first cognitive evaluation of four state-of-the-art Internet search engines: Google (i.e., Google and Scholar.Google), MedQA, Onelook, and PubMed for answering definitional questions (i.e., questions with the format of "What is X?") posed by physicians. Onelook is a portal for online definitions, and MedQA is a question answering system that automatically generates short texts to answer specific biomedical questions. Our evaluation criteria include quality of answer, ease of use, time spent, and number of actions taken. Our results show that MedQA outperforms Onelook and PubMed in most of the criteria, and that MedQA surpasses Google in time spent and number of actions, two important efficiency criteria. Our results show that Google is the best system for quality of answer and ease of use. We conclude that Google is an effective search engine for medical definitions, and that MedQA exceeds the other search engines in that it provides users direct answers to their questions; while the users of the other search engines have to visit several sites before finding all of the pertinent information.

  18. The communication skills used by deaf children and their hearing peers in a question-and-answer game context.

    PubMed

    Toe, Dianne M; Paatsch, Louise E

    2010-01-01

    Communication is frequently characterized by a sequence of questions and answers. Little is known about how well students who are deaf or hard of hearing (deaf/HH) understand their hearing classmates in the context of an inclusive setting. This study explored the communication skills used by deaf/HH children when asking and answering questions in a "trivia" game with their hearing peers. Thirty-four children with normal hearing and 34 children with a hearing loss ranging from mild to profound (>90 dB HL) participated in this study. Each of the 34 dyads included 1 child with normal hearing and 1 child with hearing loss, matched by gender and grade level at school. Dyads were videotaped and analyzed. Pairs were compared in terms of their capacity to repeat the question, strategies used to seek information, and accuracy of responses. Results showed that the group of hearing children was able to repeat more questions verbatim compared to the deaf/HH children. The deaf/HH group required a significantly greater number of repetitions, sought a greater number of general clarifications, and correctly answered more questions compared with the group of hearing children. The implications of these findings are discussed in terms of peer communication and pragmatic skill development. PMID:20299450

  20. Can primary care physicians' questions be answered using the medical journal literature?

    PubMed Central

    Gorman, P N; Ash, J; Wykoff, L

    1994-01-01

    Medical librarians and informatics professionals believe the medical journal literature can be useful in clinical practice, but evidence suggests that practicing physicians do not share this belief. The authors designed a study to determine whether a random sample of "native" questions asked by primary care practitioners could be answered using the journal literature. Participants included forty-nine active, nonacademic primary care physicians providing ambulatory care in rural and nonrural Oregon, and seven medical librarians. The study was conducted in three stages: (1) office interviews with physicians to record clinical questions; (2) online searches to locate answers to selected questions; and (3) clinician feedback regarding the relevance and usefulness of the information retrieved. Of 295 questions recorded during forty-nine interviews, 60 questions were selected at random for searches. The average total time spent searching for and selecting articles for each question was forty-three minutes. The average cost per question searched was $27.37. Clinician feedback was received for 48 of 56 questions (four physicians could not be located, so their questions were not used in tabulating the results). For 28 questions (56%), clinicians judged the material relevant; for 22 questions (46%) the information provided a "clear answer" to their question. They expected the information would have had an impact on their patient in nineteen (40%) cases, and an impact on themselves or their practice in twenty-four (51%) cases. If the results can be generalized, and if the time and cost of performing searches can be reduced, increased use of the journal literature could significantly improve the extent to which primary care physicians' information needs are met.

  2. A Medical Consultation Service on Facebook: Descriptive Analysis of Questions Answered

    PubMed Central

    2014-01-01

    Background Social media is used increasingly by the general public to access health information. However, a lack of models for health information distribution limits the presence of publicly funded services on social media sites. Objective The goal of the study was to present a model for delivering child health information to parents through a social media site. Methods A Facebook site was launched for 11 months based on a question-and-answer service produced by a pediatrician and open to Facebook users over 18 years old. If the answer did not include a further referral to a health care service provider, the question was considered comprehensively answered. The site was funded by a pharmaceutical company, and it included an advertisement of a pharmaceutical product for children’s fever and pain. Results During the study, 768 questions were submitted: an average of 69.8 (SD 31.7) per month. There were 245,533 independent Facebook users on the site, with an average of 727.0 (SD 2280.6) per day. Infections were the most common theme in questions (355/768, 46.2%). Questions were more likely to be comprehensively answered if they were related to infections (279/355, 78.6%) than questions related to non-infectious symptoms (265/423, 64.2%, P=.003). Conclusions On this site aimed at parents of small children, personalized answers were an effective way of delivering information. The service is likely to have reduced the need for further contacts with a health care service provider in more than half of the cases. The site could serve as a model for publicly funded health information distribution. PMID:25189182

  19. Vector measure for the intelligence of a Question-Answering (Q-A) system

    SciTech Connect

    Srivastava, A.; Rajaraman, V.

    1995-05-01

    The problem of quantification of intelligence of humans, and of intelligent systems, has been a challenging and controversial topic. IQ tests have been traditionally used to quantify human intelligence based on results of test designed by psychologists. It is in general very difficult to quantify intelligence. In this paper we consider a simple Question-Answering (Q-A) system and use this to quantify intelligence. We quantify intelligence as a vector with three components. The components consist of a measure of knowledge in asking questions, effectiveness of questions asked, and correctness of deduction. We formalize these parameters and have conducted experiments on humans to measure these parameters. 20 refs.

    Summer Geophysics Field Camp is part of the core requirement for undergraduate Geophysics majors at Boise State University (CSM), as well as at Colorado School of Mines (CSM). We have found it to be most effectively taught when the target of the camp involves answering questions, which impact society. For example, currently the CSM/BSU geophysics summer camp focuses on ground water resources and geothermal potential in the Upper Arkansas River Basin, a part of the Rio Grande Rift system in Chaffee County, Colorado. A prime goal is to train students how to combine diverse sources of information into a unified interpretation: Students examine lithologies and structures on the periphery of the basin. Cross sections are constructed to predict the geophysical signature. Geophysical tools then are used to ascertain the gross structure and examine subsurface conditions in greater detail. These tools include surveying, regional gravity, deep and shallow seismic surveys, magnetics, DC resistivity, Ground Penetrating Radar, electromagnetics, hydrochemistry, and karaoke. While BSU and CSM own a considerable amount of geophysical hardware, our field camps are only possible because of extensive support by corporations and governmental agencies. In addition, the Society of Exploration Geohysics (SEG) Foundation provides financial support, Chaffee County assists with housing costs, and local land owners provide open access. In turn, the field camp results aid the community of Chaffee County in assessing their water resources for long term growth planning, as well as understanding the geothermal potential for hydroelectric power generation. BSU is currently exploring with the SEG Foundation under the Geophysicists Without Borders program to apply this model of combined education and social outreach in the form a geophysics camp for Southeast Asia, where we propose to study geohazards,geoarcheology and groundwater issues.

  5. Comparing the Use of an Online Expert Health Network against Common Information Sources to Answer Health Questions

    PubMed Central

    Lenderink, Annet F; van Dijk, Frank JH; Hulshof, Carel TJ

    2012-01-01

    Background Many workers have questions about occupational safety and health (OSH). It is unknown whether workers are able to find correct, evidence-based answers to OSH questions when they use common information sources, such as websites, or whether they would benefit from using an easily accessible, free-of-charge online network of OSH experts providing advice. Objective To assess the rate of correct, evidence-based answers to OSH questions in a group of workers who used an online network of OSH experts (intervention group) compared with a group of workers who used common information sources (control group). Methods In a quasi-experimental study, workers in the intervention and control groups were randomly offered 2 questions from a pool of 16 standardized OSH questions. Both questions were sent by mail to all participants, who had 3 weeks to answer them. The intervention group was instructed to use only the online network ArboAntwoord, a network of about 80 OSH experts, to solve the questions. The control group was instructed that they could use all information sources available to them. To assess answer correctness as the main study outcome, 16 standardized correct model answers were constructed with the help of reviewers who performed literature searches. Subsequently, the answers provided by all participants in the intervention (n = 94 answers) and control groups (n = 124 answers) were blinded and compared with the correct model answers on the degree of correctness. Results Of the 94 answers given by participants in the intervention group, 58 were correct (62%), compared with 24 of the 124 answers (19%) in the control group, who mainly used informational websites found via Google. The difference between the 2 groups was significant (rate difference = 43%, 95% confidence interval [CI] 30%–54%). Additional analysis showed that the rate of correct main conclusions of the answers was 85 of 94 answers (90%) in the intervention group and 75 of 124 answers (61%) in the control group (rate difference = 29%, 95% CI 19%–40%). Remarkably, we could not identify differences between workers who provided correct answers and workers who did not on how they experienced the credibility, completeness, and applicability of the information found (P > .05). Conclusions Workers are often unable to find correct answers to OSH questions when using common information sources, generally informational websites. Because workers frequently misjudge the quality of the information they find, other strategies are required to assist workers in finding correct answers. Expert advice provided through an online expert network can be effective for this purpose. As many people experience difficulties in finding correct answers to their health questions, expert networks may be an attractive new source of information for health fields in general.

  6. INDUSTRIAL CONTROL SYSTEM CYBER SECURITY: QUESTIONS AND ANSWERS RELEVANT TO NUCLEAR FACILITIES, SAFEGUARDS AND SECURITY

    SciTech Connect

    2011-07-01

    Typical questions surrounding industrial control system (ICS) cyber security always lead back to: What could a cyber attack do to my system(s) and; how much should I worry about it? These two leading questions represent only a fraction of questions asked when discussing cyber security as it applies to any program, company, business, or organization. The intent of this paper is to open a dialog of important pertinent questions and answers that managers of nuclear facilities engaged in nuclear facility security and safeguards should examine, i.e., what questions should be asked; and how do the answers affect an organization's ability to effectively safeguard and secure nuclear material. When a cyber intrusion is reported, what does that mean? Can an intrusion be detected or go un-noticed? Are nuclear security or safeguards systems potentially vulnerable? What about the digital systems employed in process monitoring, and international safeguards? Organizations expend considerable efforts to ensure that their facilities can maintain continuity of operations against physical threats. However, cyber threats particularly on ICSs may not be well known or understood, and often do not receive adequate attention. With the disclosure of the Stuxnet virus that has recently attacked nuclear infrastructure, many organizations have recognized the need for an urgent interest in cyber attacks and defenses against them. Several questions arise including discussions about the insider threat, adequate cyber protections, program readiness, encryption, and many more. These questions, among others, are discussed so as to raise the awareness and shed light on ways to protect nuclear facilities and materials against such attacks.

    Kamcharean, Chanwit; Wattanakasiwich, Pornrat

    The objective of this study was to diagnose misconceptions of Thai and Lao students in thermodynamics by using a two-tier multiple-choice test. Two-tier multiple choice questions consist of the first tier, a content-based question and the second tier, a reasoning-based question. Data of student understanding was collected by using 10 two-tier multiple-choice questions. Thai participants were the first-year students (N = 57) taking a fundamental physics course at Chiang Mai University in 2012. Lao participants were high school students in Grade 11 (N = 57) and Grade 12 (N = 83) at Muengnern high school in Xayaboury province, Lao PDR. As results, most students answered content-tier questions correctly but chose incorrect answers for reason-tier questions. When further investigating their incorrect reasons, we found similar misconceptions as reported in previous studies such as incorrectly relating pressure with temperature when presenting with multiple variables.

  10. Evaluating the Use of In-situ and Remote Sensing Data to Answer Critical Hydrological Questions

    2014-12-01

    Water demands of the 21st Century pose challenges for effective decision-making and viable management of hydrological resources. As competition for water becomes more complex, the use of technology to maximize finite water resources becomes increasingly critical. Therefore, accurate methods of gauging relevant data streams must be developed and improved at every level, from basic and applied research to water management to policy oversight. How can the relative value for answering critical hydrologic questions of prospective data streams be gauged? Advancements in technology are producing multiple new sources of hydrological data from in-situ platforms and the developing resource of remote sensing platforms. The in-situ and remote sensing data available from these new sources can be used complementarily to provide answers to critical water resource management questions. Analyses that identify which combination of data resources will offer the most effective methodology for quantifying hydrological variables will establish new best practices for water management. We are going to use new techniques of data assimilation to establish a process for identifying and evaluating the method that provides the most quantitative means for answering key hydrological questions. This research will outline a method for evaluating specific in-situ and remote sensing data sets for complementary use in managing flood hazards, assessing water flows, and improving irrigation practices, to name a few. This will result in improved understanding of multisensory data and its analysis which, in turn, will lead to better informed decision-making, improved policy development and future governance regarding hydrological systems in any given watershed scenario. *** Image: Preliminary Research Road Map / Poster will highlight Quantitative Research (step 1)

    Women in childbearing age frequently suffer from mental illness. Maternal psychiatric disorders may have a devastating impact on the fetus and the newborn. Thus treating or preventing relapse of these disorders during pregnancy and puerperium is a clinical and ethical duty with the necessity to avoid or minimize fetal or neonatal drug exposure. Though there are many guidelines and comprehensive reviews regarding drug safety in pregnancy and lactation, the application of these recommendations into clinical practice appears to be complex. Hence, we present some clinical questions with answers considering the available literature on safety of psychotropics in pregnancy and lactation. PMID:19742205

    To address one of the most important questions in planetary science Is there life on Mars? The scientific community must turn to less costly means of exploring the surface of the Red Planet. The United Kingdom's Beagle 2 Mars lander concept was a small meter-size lander with a scientific payload constituting a large proportion of the flown mass designed to supply answers to the question about life on Mars. A possible reason why Beagle 2 did not send any data was that it was a one-off attempt to land. As Steve Squyres said at the time: "It's difficult to land on Mars - if you want to succeed you have to send two of everything".

    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.

    Battery second use – putting used plug-in electric vehicle (PEV) batteries into secondary service following their automotive tenure – has been proposed as a means to decrease the cost of PEVs while providing low cost energy storage to other fields (e.g. electric utility markets). To understand the value of used automotive batteries, however, we must first answer several key questions related to National Renewable Energy Laboratory (NREL) has developed a methodology and the requisite tools to answer these questions, including NREL’s Battery Lifetime Simulation Tool (BLAST). Herein we introduce these methods and tools, and demonstrate their application. We have found that capacity fade from automotive use has a much larger impact on second use value than resistance growth. Where capacity loss is driven by calendar effects more than cycling effects, average battery temperature during automotive service – which is often driven by climate – is found to be the single factor with the largest effect on remaining value. Installing hardware and software capabilities onboard the vehicle that can both infer remaining battery capacity from in-situ measurements, as well as track average battery temperature over time, will thereby facilitate the second use of automotive batteries.

  15. Answering the right question - integration of InSAR with other datasets

    NASA Astrophysics Data System (ADS)

    Holley, Rachel; McCormack, Harry; Burren, Richard

    2014-05-01

    The capabilities of satellite Interferometric Synthetic Aperture Radar (InSAR) are well known, and utilized across a wide range of academic and commercial applications. However there is a tendency, particularly in commercial applications, for users to ask 'What can we study with InSAR?'. When establishing a new technique this approach is important, but InSAR has been possible for 20 years now and, even accounting for new and innovative algorithms, this ground has been thoroughly explored. Too many studies conclude 'We show the ground is moving here, by this much', and mention the wider context as an afterthought. The focus needs to shift towards first asking the right questions - in fields as diverse as hazard awareness, resource optimization, financial considerations and pure scientific enquiry - and then working out how to achieve the best possible answers. Depending on the question, InSAR (and ground deformation more generally) may provide a large or small contribution to the overall solution, and there are usually benefits to integrating a number of techniques to capitalize on the complementary capabilities and provide the most useful measurements. However, there is still a gap between measurements and answers, and unlocking the value of the data relies heavily on appropriate visualization, integrated analysis, communication between technique and application experts, and appropriate use of modelling. We present a number of application examples, and demonstrate how their usefulness can be transformed by moving from a focus on data to answers - integrating complementary geodetic, geophysical and geological datasets and geophysical modeling with appropriate visualization, to enable comprehensive solution-focused interpretation. It will also discuss how forthcoming developments are likely to further advance realisation of the full potential satellite InSAR holds.

    2010-01-01

    BACKGROUND The Internet is an increasingly important source of health information. OBJECTIVE To assess how well common websites answered patients’ questions regarding inflammatory bowel disease (IBD). METHODS Thirty websites were identified and evaluated. Based on a previous survey of patient information needs, a comprehensive question list was developed in the three following areas: medical information (seven items), medical treatment (six items) and self-management (eight items). The websites were evaluated for the amount of information they provided to answer each question using two standard measures of information quality – the DISCERN and the Ensuring Quality Information for Patients scales. RESULTS Four particularly strong websites, scoring highest (on a scale from 1 to 5) in terms of IBD information, were the Crohn’s and Colitis Foundation of America (mean information score 4.3), About.com (4.2), HealthCentral (3.8) and WebMD (3.8). These websites also scored well on the DISCERN and the Ensuring Quality Information for Patients quality scales. Most websites provided at least adequate information on common symptoms, complications, treatments and what is known (or not known) about the causes of IBD. However, many web-sites did not provide adequate information about prognosis, possible side effects of treatment and risks of developing cancer. Information regarding self-management was covered to a very limited extent. CONCLUSION Websites could be strengthened by providing more of the information patients deem to be important, and by more clearly identifying sources of information and the date the information was updated. Most websites would benefit from more attention given to reducing the reading level and improving the organization of material. PMID:21157582

  7. Why Students Answer TIMSS Science Test Items the Way They Do

    NASA Astrophysics Data System (ADS)

    Harlow, Ann; Jones, Alister

    2004-04-01

    The purpose of this study was to explore how Year 8 students answered Third International Mathematics and Science Study (TIMSS) questions and whether the test questions represented the scientific understanding of these students. One hundred and seventy-seven students were tested using written test questions taken from the science test used in the Third International Mathematics and Science Study. The degree to which a sample of 38 children represented their understanding of the topics in a written test compared to the level of understanding that could be elicited by an interview is presented in this paper. In exploring student responses in the interview situation this study hoped to gain some insight into the science knowledge that students held and whether or not the test items had been able to elicit this knowledge successfully. We question the usefulness and quality of data from large-scale summative assessments on their own to represent student scientific understanding and conclude that large scale written test items, such as TIMSS, on their own are not a valid way of exploring students'' understanding of scientific concepts. Considerable caution is therefore needed in exploiting the outcomes of international achievement testing when considering educational policy changes or using TIMSS data on their own to represent student understanding.

  8. A Cost-Consequences Analysis of a Primary Care Librarian Question and Answering Service

    McGowan, Jessie; Hogg, William; Zhong, Jianwei; Zhao, Xue

    2012-01-01

    Background Cost consequences analysis was completed from randomized controlled trial (RCT) data for the Just-in-time (JIT) librarian consultation service in primary care that ran from October 2005 to April 2006. The service was aimed at providing answers to clinical questions arising during the clinical encounter while the patient waits. Cost saving and cost avoidance were also analyzed. The data comes from eighty-eight primary care providers in the Ottawa area working in Family Health Networks (FHNs) and Family Health Groups (FHGs). Methods We conducted a cost consequences analysis based on data from the JIT project [1]. We also estimated the potential economic benefit of JIT librarian consultation service to the health care system. Results The results show that the cost per question for the JIT service was $38.20. The cost could be as low as $5.70 per question for a regular service. Nationally, if this service was implemented and if family physicians saw additional patients when the JIT service saved them time, up to 61,100 extra patients could be seen annually. A conservative estimate of the cost savings and cost avoidance per question for JIT was $11.55. Conclusions The cost per question, if the librarian service was used at full capacity, is quite low. Financial savings to the health care system might exceed the cost of the service. Saving physician's time during their day could potentially lead to better access to family physicians by patients. Implementing a librarian consultation service can happen quickly as the time required to train professional librarians to do this service is short. PMID:22442727

  9. Turn-taking: a case study of early gesture and word use in answering WHERE and WHICH questions

    Clark, Eve V.; Lindsey, Kate L.

    2015-01-01

    When young children answer questions, they do so more slowly than adults and appear to have difficulty finding the appropriate words. Because children leave gaps before they respond, it is possible that they could answer faster with gestures than with words. In this study, we compare gestural and verbal responses from one child between the ages of 1;4 and 3;5, to adult Where and Which questions, which can be answered with gestures and/or words. After extracting all adult Where and Which questions and child answers from longitudinal videotaped sessions, we examined the timing from the end of each question to the start of the response, and compared the timing for gestures and words. Child responses could take the form of a gesture or word(s); the latter could be words repeated from the adult question or new words retrieved by the child. Or responses could be complex: a gesture + word repeat, gesture + new word, or word repeat + new word. Gestures were the fastest overall, followed successively by word-repeats, then new-word responses. This ordering, with gestures ahead of words, suggests that the child knows what to answer but needs more time to retrieve any relevant words. In short, word retrieval and articulation appear to be bottlenecks in the timing of responses: both add to the planning required in answering a question. PMID:26217253

  10. Developing an Ontology for Improving Question Answering in the Agricultural Domain

    NASA Astrophysics Data System (ADS)

    Vila, Katia; Ferrández, Antonio

    Numerous resources have been developed to have a better access to scientific information in the agricultural domain. However, they are rather concerned with providing general metadata of bibliographic references, which prevents users from accessing precise agricultural information in a transparent and simple manner. To overcome this drawback, in this paper, we propose to use domain-specific resources to improve the results in the answers obtained by an Open-Domain Question Answering (QA) system, obtaining a QA system for the agricultural domain. Specifically, it has been made by (i) creating an ontology that covers concepts and relationships from journal publications of the agricultural domain, (ii) enriching this ontology with some public data sources (e.g the Agrovoc thesaurus and the WordNet lexical database) in order to be precisely used in an agricultural domain, and (iii) aligning this enriched ontology with articles from our case-study journal, i.e. the Cuban Journal of Agricultural Science. Finally, we have developed a set of experiments in order to show the usefulness of our approach.

  11. Method for Atypical Opinion Extraction from Ungrammatical Answers in Open-ended Questions

    Hiramatsu, Ayako; Tamura, Shingo; Oiso, Hiroaki; Komoda, Norihisa

    This paper presents a method for atypical opinion extraction from ungrammatical answers to open-ended questions supplied through cellular phones. The proposed system excludes typical opinions and extracts only atypical opinions. To cope with incomplete syntax of texts due to the input by cellular phones, the system treats the opinions as the sets of keywords. The combinations of words are established beforehand in a typical word database. Based on the ratio of typical word combinations in sentences of an opinion, the system classifies the opinion typical or atypical. When typical word combinations are sought in an opinion, the system considers the word order and the distance of difference between the positions of words to exclude unnecessary combinations. Furthermore, when an opinion includes meanings the system divides the opinion into phrases at each typical word combination. By applying questionnaire data supplied by users of a mobile game content when they cancel their account, the extraction accuracy of the proposed system was confirmed.

  12. Compatible solute influence on nucleic acids: Many questions but few answers

    PubMed Central

    Kurz, Matthias

    2008-01-01

    Compatible solutes are small organic osmolytes including but not limited to sugars, polyols, amino acids, and their derivatives. They are compatible with cell metabolism even at molar concentrations. A variety of organisms synthesize or take up compatible solutes for adaptation to extreme environments. In addition to their protective action on whole cells, compatible solutes display significant effects on biomolecules in vitro. These include stabilization of native protein and nucleic acid structures. They are used as additives in polymerase chain reactions to increase product yield and specificity, but also in other nucleic acid and protein applications. Interactions of compatible solutes with nucleic acids and protein-nucleic acid complexes are much less understood than the corresponding interactions of compatible solutes with proteins. Although we may begin to understand solute/nucleic acid interactions there are only few answers to the many questions we have. I summarize here the current state of knowledge and discuss possible molecular mechanisms and thermodynamics. PMID:18522725

  13. Disaster care: questions and answers on pandemic influenza. Striking a balance between risk and preparedness.

    PubMed

    Davey, Victoria J

    2007-07-01

    Disaster planning based on events such as floods or hurricanes, which are local or regional in scale, may be inadequate for responding to a lethal influenza pandemic that has the potential to overwhelm existing public health infrastructures. However, if a mild strain of the virus achieves pandemic proportions, the current public health system may be able to manage the outbreak relatively easily. Therefore, the challenge in pandemic influenza planning is to find a balance between risk and preparedness. Planners and policy makers must make realistic estimates of the consequences of a pandemic and allocate limited resources wisely, so that everyday health care and social needs aren't shortchanged. This article examines what we've learned from past influenza pandemics and answers some frequently asked questions about pandemics and how to prepare for them. PMID:17589231

    2010-01-01

    Decades of experiments in small animals had tipped the balance of opinion away from antibodies as a cause of transplant rejection, but clinical experience, especially with sensitized patients, has convinced basic immunologists of the need to develop models to investigate mechanisms underlying antibody-mediated rejection (AMR). This resurgent interest has resulted in several new rodent models to investigate antibody-mediated mechanisms of heart and renal allograft injury, but satisfactory models of chronic AMR remain more elusive. Nevertheless, these new studies have begun to reveal many insights into the molecular and pathological sequelae of antibody binding to the allograft endothelium. In addition, complement-independent and –dependent effects of antibodies on endothelial cells have been identified in vitro. As small animals models become better defined, it is anticipated that they will be more widely used to answer further questions concerning mechanisms of antibody-mediated tissue injury as well as to design therapeutic interventions.

  15. The ContactFinder agent: Answering bulletin board questions with referrals

    Krulwich, B.; Burkey, C.

    1996-12-31

    ContactFinder is an intelligent agent whose approach to assisting users is valuable and innovative in the following four ways. First, ContactFinder operates proactively in reading and responding to messages on electronic bulletin boards rather than acting in response to user queries. Second, ContactFinder assists users by referring them to other people who can help them, rather than attempting to find information that directly answers the user`s specific question. Third, ContactFinder categorizes messages and extracts their topic areas using a set of heuristics that are very efficient and demonstrably highly effective. Fourth, ContactFinder posts its referrals back to the bulletin boards rather than simply communicating with specific users, to increase the information density and connectivity of the system. This paper discusses these aspects of the system and demonstrates their effectiveness in over six months of use on a large-scale internal bulletin board.

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

    NASA Astrophysics Data System (ADS)

    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.

  1. Omega-3 polyunsaturated fatty acids in Alzheimer's disease: key questions and partial answers.

    PubMed

    Calon, F

    2011-08-01

    The current rise in the prevalence of Alzheimer's disease (AD) is unfortunately not matched by new treatment options. In the last 10 years, epidemiological, preclinical and clinical data have enlightened the possible preventive action of omega-3 polyunsaturated fatty acids (n-3 PUFA) in AD and other diseases. While the contribution of recent studies to our general knowledge is priceless, many important new questions have been raised. In the present review, we aim at addressing some of these timely interrogations. First, the transport of n-3 PUFA across the blood-brain barrier is underscored based on preclinical data. Second, the relative contribution of two neuroactive n-3 PUFA found in fish oil, docosahexaenoic acid (DHA; 22:6 n-3) and eicosapentaenoic acid (EPA, 20:5 n-3), remains unclear and is reviewed. Third, clinical trials on neurodegenerative diseases consistently remind us that treating early is critical, and this is likely to be the case with n-3 PUFA in AD as well. Fourth, we draw attention to the possibility that the current knowledge translation approach to make health recommendations might have to be adapted to non-patentable endogenous compounds like n-3 PUFA. We propose that answers to these critical questions will be instrumental toward a rational use of n-3 PUFA in AD. PMID:21605051

  2. Explaining topic prevalence in answers to open-ended survey questions about climate change

    NASA Astrophysics Data System (ADS)

    2015-08-01

    Citizens’ opinions are crucial for action on climate change, but are, owing to the complexity of the issue, diverse and potentially unformed. We contribute to the understanding of public views on climate change and to knowledge needed by decision-makers by using a new approach to analyse answers to the open survey question `what comes to mind when you hear the words `climate change’?’. We apply automated text analysis, specifically structural topic modelling, which induces distinct topics based on the relative frequencies of the words used in 2,115 responses. From these data, originating from the new, nationally representative Norwegian Citizen Panel, four distinct topics emerge: Weather/Ice, Future/Impact, Money/Consumption and Attribution. We find that Norwegians emphasize societal aspects of climate change more than do respondents in previous US and UK studies. Furthermore, variables that explain variation in closed questions, such as gender and education, yield different and surprising results when employed to explain variation in what respondents emphasize. Finally, the sharp distinction between scepticism and acceptance of conventional climate science, often seen in previous studies, blurs in many textual responses as scepticism frequently turns into ambivalence.

  15. Measuring University students' understanding of the greenhouse effect - a comparison of multiple-choice, short answer and concept sketch assessment tools with respect to students' mental models

    NASA Astrophysics Data System (ADS)

    Gold, A. U.; Harris, S. E.

    2013-12-01

    The greenhouse effect comes up in most discussions about climate and is a key concept related to climate change. Existing studies have shown that students and adults alike lack a detailed understanding of this important concept or might hold misconceptions. We studied the effectiveness of different interventions on University-level students' understanding of the greenhouse effect. Introductory level science students were tested for their pre-knowledge of the greenhouse effect using validated multiple-choice questions, short answers and concept sketches. All students participated in a common lesson about the greenhouse effect and were then randomly assigned to one of two lab groups. One group explored an existing simulation about the greenhouse effect (PhET-lesson) and the other group worked with absorption spectra of different greenhouse gases (Data-lesson) to deepen the understanding of the greenhouse effect. All students completed the same assessment including multiple choice, short answers and concept sketches after participation in their lab lesson. 164 students completed all the assessments, 76 completed the PhET lesson and 77 completed the data lesson. 11 students missed the contrasting lesson. In this presentation we show the comparison between the multiple-choice questions, short answer questions and the concept sketches of students. We explore how well each of these assessment types represents student's knowledge. We also identify items that are indicators of the level of understanding of the greenhouse effect as measured in correspondence of student answers to an expert mental model and expert responses. Preliminary data analysis shows that student who produce concept sketch drawings that come close to expert drawings also choose correct multiple-choice answers. However, correct multiple-choice answers are not necessarily an indicator that a student produces an expert-like correlating concept sketch items. Multiple-choice questions that require detailed knowledge of the greenhouse effect (e.g. direction of re-emission of infrared energy from greenhouse gas) are significantly more likely to be answered correctly by students who also produce expert-like concept sketch items than by students who don't include this aspect in their sketch and don't answer the multiple choice questions correctly. This difference is not as apparent for less technical multiple-choice questions (e.g. type of radiation emitted by Sun). Our findings explore the formation of student's mental models throughout different interventions and how well the different assessment techniques used in this study represent the student understanding of the overall concept.

  18. Perspectives from the Avian Phylogenomics Project: Questions that Can Be Answered with Sequencing All Genomes of a Vertebrate Class.

    Jarvis, Erich D

    2016-02-15

    The rapid pace of advances in genome technology, with concomitant reductions in cost, makes it feasible that one day in our lifetime we will have available extant genomes of entire classes of species, including vertebrates. I recently helped cocoordinate the large-scale Avian Phylogenomics Project, which collected and sequenced genomes of 48 bird species representing most currently classified orders to address a range of questions in phylogenomics and comparative genomics. The consortium was able to answer questions not previously possible with just a few genomes. This success spurred on the creation of a project to sequence the genomes of at least one individual of all extant ?10,500 bird species. The initiation of this project has led us to consider what questions now impossible to answer could be answered with all genomes, and could drive new questions now unimaginable. These include the generation of a highly resolved family tree of extant species, genome-wide association studies across species to identify genetic substrates of many complex traits, redefinition of species and the species concept, reconstruction of the genomes of common ancestors, and generation of new computational tools to address these questions. Here I present visions for the future by posing and answering questions regarding what scientists could potentially do with available genomes of an entire vertebrate class. PMID:26884102

  19. Using LQCD to answer questions about hadronic interactions: a perspective from a traditional nuclear theorist

    NASA Astrophysics Data System (ADS)

    Luu, Thomas

    2009-05-01

    As computational resources increase and better algorithms are implemented, LQCD calculations of hadronic interaction observables become less of a pipe dream, and more of a reality, and will eventually become the status quo. One of the greatest strengths of LQCD calculations in the realm of low-energy nuclear physics comes from its predictive capability, as many hadronic systems not accessible by experiments can be calculated on the lattice. These calculations in turn have direct implications to nuclear structure, nuclear reactions, and nuclear astrophysics, as well as the broader nuclear physics community. Thus the import of LQCD on low-energy nuclear physics cannot be overlooked, nor understated. In this talk I discuss current and ongoing efforts to extract hadronic interaction parameters from LQCD, enumerating current difficulties placed by available computer resources and algorithm limitations. I will also talk about future possibilities coming from increased computer resources and algorithm development, giving examples of how such calculations can answer longstanding questions in traditional nuclear physics. Finally, I will discuss the role that national labs can and should play in the area of LQCD as applied to low-energy nuclear physics.

  20. Ten common questions (and their answers) about off-label drug use.

    PubMed

    Wittich, Christopher M; Burkle, Christopher M; Lanier, William L

    2012-10-01

    The term off-label drug use (OLDU) is used extensively in the medical literature, continuing medical education exercises, and the media. Yet, we propose that many health care professionals have an underappreciation of its definition, prevalence, and implications. This article introduces and answers 10 questions regarding OLDU in an effort to clarify the practice's meaning, breadth of application, acceptance, and liabilities. Off-label drug use involves prescribing medications for indications, or using a dosage or dosage form, that have not been approved by the US Food and Drug Administration. Since the Food and Drug Administration does not regulate the practice of medicine, OLDU has become common. It occurs in every specialty of medicine, but it may be more common in areas of medicine in which the patient population is less likely to be included in clinical trials (eg, pediatric, pregnant, or psychiatric patients). Pharmaceutical companies are not allowed to promote their medications for an off-label use, which has lead to several large settlements for illegal marketing. To limit liability, physicians should prescribe medications only for indications that they believe are in the best interest of the patient. In addition, health care professionals should educate themselves about OLDU to weigh the risks and benefits and provide the best possible care for their patients. PMID:22877654

  1. Creating and using real-world evidence to answer questions about clinical effectiveness.

    PubMed

    De Lusignan, Simon; Crawford, Laura; Munro, Neil

    2015-01-01

    New forms of evidence are needed to complement evidence generated from randomised controlled trials (RCTs). Real-World Evidence (RWE) is a potential new form of evidence, but remains undefined.This paper sets to fill that gap by defining RWE as the output from a rigorous research process which: (1) includes a clear a priori statement of a hypothesis to be tested or research question to be answered; (2) defines the data sources that will be used and critically appraises their strengths and weaknesses; and (3) applies appropriate methods, including advanced analytics. These elements should be set out in advance of the study commencing, ideally in a published protocol.The strengths of RWE studies are that they are more inclusive than RCTs and can enable an evidence base to be developed around real-world effectiveness and to start to address the complications of managing other real-world problems such as multimorbidity. Computerised medical record systems and big data provide a rich source of data for RWE studies.However, guidance is needed to help assess the rigour of RWE studies so that the strength of recommendations based on their output can be determined. Additionally, RWE advanced analytics methods need better categorisation and validation.We predict that the core role of RCTs will shift towards assessing safety and achieving regulatory compliance. RWE studies, notwithstanding their limitations, may become established as the best vehicle to assess efficacy. PMID:26577427

    Although the incidence of morbidly adherent placenta (MAP) has risen progressively in the last two decades, there remains uncertainty about the diagnosis and management of this condition. The aim of this review is to provide up-to-date and evidence-based answers to common clinical questions regarding the diagnosis and management of MAP. Different risk factors have been associated with MAP; however, previous Cesarean section and placenta previa are the most frequently associated. Ultrasound is the primary method for diagnosing MAP and has a good overall diagnostic accuracy for its detection. When considering the different ultrasound signs of MAP, color Doppler seems to provide the best diagnostic performance. Magnetic resonance imaging has the same accuracy in diagnosing MAP as does ultrasound examination; its use should be considered when a resective procedure, such as hysterectomy, is planned as it can provide detailed information about the topography of placental invasion and predict difficulties that may arise in surgery. The optimal gestational age for delivery in pregnancies with MAP is yet to be established; planning surgery between 35 and 36?weeks of gestation provides the best balance between fetal maturity and the risk of unexpected episodes of heavy bleeding, which are more likely to occur with delivery after this timepoint, especially in severe cases of MAP. The optimal surgical approach to MAP depends on multiple factors, including availability of an experienced team, specific surgical skills and hospital resources. Copyright © 2015 ISUOG.

    1999-01-01

    STS-103 Commander Curtis L. Brown Jr. answers a question from the media about the mission. As a preparation for launch, the crew have been participating in Terminal Countdown Demonstration Test (TCDT) activities at KSC. The TCDT provides the crew with emergency egress training, opportunities to inspect their mission payloads in the orbiter's payload bay, and simulated countdown exercises. Other crew members are Pilot Scott J. Kelly, and Mission Specialists Steven L. Smith, Jean-Frangois Clervoy of France, who is with the European Space Agency (ESA), John M. Grunsfeld (Ph.D.), C. Michael Foale (Ph.D.), and Claude Nicollier of Switzerland, who is also with ESA. STS-103 is a 'call-up' mission due to the need to replace and repair portions of the Hubble Space Telescope, including the gyroscopes that allow the telescope to point at stars, galaxies and planets. The STS-103 crew will be replacing a Fine Guidance Sensor, an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The mission is targeted for launch Dec. 6 at 2:37 a.m. EST.

  12. Cues Matter: Learning Assistants Influence Introductory Biology Student Interactions during Clicker-Question Discussions

    PubMed Central

    Knight, Jennifer K.; Wise, Sarah B.; Rentsch, Jeremy; Furtak, Erin M.

    2015-01-01

    The cues undergraduate biology instructors provide to students before discussions of clicker questions have previously been shown to influence student discussion. We further explored how student discussions were influenced by interactions with learning assistants (LAs, or peer coaches). We recorded and transcribed 140 clicker-question discussions in an introductory molecular biology course and coded them for features such as the use of reasoning and types of questions asked. Students who did not interact with LAs had discussions that were similar in most ways to students who did interact with LAs. When students interacted with LAs, the only significant changes in their discussions were the use of more questioning and more time spent in discussion. However, when individual LA–student interactions were examined within discussions, different LA prompts were found to generate specific student responses: question prompts promoted student use of reasoning, while students usually stopped their discussions when LAs explained reasons for answers. These results demonstrate that LA prompts directly influence student interactions during in-class discussions. Because clicker discussions can encourage student articulation of reasoning, instructors and LAs should focus on how to effectively implement questioning techniques rather than providing explanations.

  13. Problem-based learning: Using students' questions to drive knowledge construction

    NASA Astrophysics Data System (ADS)

    Chin, Christine; Chia, Li-Gek

    2004-09-01

    This study employed problem-based learning for project work in a year 9 biology class. The purpose of the study was to investigate (a) students' inspirations for their self-generated problems and questions, (b) the kinds of questions that students asked individually and collaboratively, and (c) how students' questions guided them in knowledge construction. Data sources included observation and field notes, students' written documents, audiotapes and videotapes of students working in groups, and student interviews. Sources of inspiration for students' problems and questions included cultural beliefs and folklore; wonderment about information propagated by advertisements and the media; curiosity arising from personal encounters, family members' concerns, or observations of others; and issues arising from previous lessons in the school curriculum. Questions asked individually pertained to validation of common beliefs and misconceptions, basic information, explanations, and imagined scenarios. The findings regarding questions asked collaboratively are presented as two assertions. Assertion 1 maintained that students' course of learning were driven by their questions. Assertion 2 was that the ability to ask the right'' questions and the extent to which these could be answered, were important in sustaining students' interest in the project. Implications of the findings for instructional practice are discussed.

  14. Exploring viewing behavior data from whole slide images to predict correctness of students’ answers during practical exams in oral pathology

    2015-01-01

    The way of viewing whole slide images (WSI) can be tracked and analyzed. In particular, it can be useful to learn how medical students view WSIs during exams and how their viewing behavior is correlated with correctness of the answers they give. We used software-based view path tracking method that enabled gathering data about viewing behavior of multiple simultaneous WSI users. This approach was implemented and applied during two practical exams in oral pathology in 2012 (88 students) and 2013 (91 students), which were based on questions with attached WSIs. Gathered data were visualized and analyzed in multiple ways. As a part of extended analysis, we tried to use machine learning approaches to predict correctness of students’ answers based on how they viewed WSIs. We compared the results of analyses for years 2012 and 2013 – done for a single question, for student groups, and for a set of questions. The overall patterns were generally consistent across these 3 years. Moreover, viewing behavior data appeared to have certain potential for predicting answers’ correctness and some outcomes of machine learning approaches were in the right direction. However, general prediction results were not satisfactory in terms of precision and recall. Our work confirmed that the view path tracking method is useful for discovering viewing behavior of students analyzing WSIs. It provided multiple useful insights in this area, and general results of our analyses were consistent across two exams. On the other hand, predicting answers’ correctness appeared to be a difficult task – students’ answers seem to be often unpredictable. PMID:26110095

    Objective To evaluate existing automatic speech-recognition (ASR) systems to measure their performance in interpreting spoken clinical questions and to adapt one ASR system to improve its performance on this task. Design and measurements The authors evaluated two well-known ASR systems on spoken clinical questions: Nuance Dragon (both generic and medical versions: Nuance Gen and Nuance Med) and the SRI Decipher (the generic version SRI Gen). The authors also explored language model adaptation using more than 4000 clinical questions to improve the SRI system's performance, and profile training to improve the performance of the Nuance Med system. The authors reported the results with the NIST standard word error rate (WER) and further analyzed error patterns at the semantic level. Results Nuance Gen and Med systems resulted in a WER of 68.1% and 67.4% respectively. The SRI Gen system performed better, attaining a WER of 41.5%. After domain adaptation with a language model, the performance of the SRI system improved 36% to a final WER of 26.7%. Conclusion Without modification, two well-known ASR systems do not perform well in interpreting spoken clinical questions. With a simple domain adaptation, one of the ASR systems improved significantly on the clinical question task, indicating the importance of developing domain/genre-specific ASR systems. PMID:21705457

  16. Discovery and New Frontiers: Science Missions Seeking New Answers to Timeless Questions (Invited)

    NASA Astrophysics Data System (ADS)

    Asplund, S.

    2010-12-01

    NASA's Discovery and New Frontiers missions EPOXI, Stardust-NExT, Dawn, MESSENGER, Juno, and GRAIL help comprise NASA’s Year of the Solar System. Each of these investigations is seeking answers to key science questions and each has a unique approach to sharing that quest with the public. To date, spacecraft have photographed only four comets up close. What new information will EPOXI uncover when it flies by comet Hartley 2? Will it be similar to the others or very different? How will comet Tempel 1 appear to Stardust-NExT? The Deep Impact mission sent an impactor into the path of Tempel 1 in 2005. What changes will be visible in this unprecedented return visit? Will we finally see the crater made by the impact? Dawn will arrive at asteroid Vesta in July for a year-long orbit. Then it will millions of miles more to go into orbit around dwarf planet Ceres. Using the same science instruments to study both will yield important new information. MESSENGER has already discovered new phenomena and collected considerable data in its three flybys of Mercury. Once the orbiting phase begins, this dynamic planet is guaranteed to put on a spectacular show. Juno is traveling to the massive gas giant Jupiter to extend our knowledge about this wondrous body. Does it have a solid core? How much water does the atmosphere contain? How does the planet’s enormous magnetic force field affect its atmosphere? GRAIL will send twin space probes flying in tandem around the Moon to take precise gravity field measurements to help determine the structure and composition of the lunar interior from crust to core. In early 2011, the Discovery and New Frontiers Programs are planning a teacher “workshop without walls” to help celebrate YSS! Teachers will gather at 4 or 5 sites across the country, including California, Texas, Minnesota, and Maryland, and tune in via NASA’s digital learning network to hear talks about the missions and their science objectives. The workshops will also include trainings with hands-on activities the teachers can take back to their classroom.

  7. The 5 key questions coping with risks due to natural hazards, answered by a case study

    NASA Astrophysics Data System (ADS)

    Hardegger, P.; Sausgruber, J. T.; Schiegg, H. O.

    2009-04-01

    Based on Maslow's hierarchy of needs, human endeavours concern primarily existential needs, consequently, to be safeguarded against both natural as well as man made threads. The subsequent needs are to realize chances in a variety of fields, as economics and many others. Independently, the 5 crucial questions are the same as for coping with risks due to natural hazards specifically. These 5 key questions are I) What is the impact in function of space and time ? II) What protection measures comply with the general opinion and how much do they mitigate the threat? III) How can the loss be adequately quantified and monetized ? IV) What budget for prevention and reserves for restoration and compensation are to be planned ? V) Which mix of measures and allocation of resources is sustainable, thus, optimal ? The 5 answers, exemplified by a case study, concerning the sustainable management of risk due to the debris flows by the Enterbach / Inzing / Tirol / Austria, are as follows : I) The impact, created by both the propagation of flooding and sedimentation, has been forecasted by modeling (numerical simulation) the 30, 50, 100, 150, 300 and 1000 year debris flow. The input was specified by detailed studies in meteorology, precipitation and runoff, in geology, hydrogeology, geomorphology and slope stability, in hydraulics, sediment transport and debris flow, in forestry, agriculture and development of communal settlement and infrastructure. All investigations were performed according to the method of ETAlp (Erosion and Transport in Alpine systems). ETAlp has been developed in order to achieve a sustainable development in alpine areas and has been evaluated by the research project "nab", within the context of the EU-Interreg IIIb projects. II) The risk mitigation measures of concern are in hydraulics at the one hand and in forestry at the other hand. Such risk management is evaluated according to sustainability, which means economic, ecologic and social, in short, "triple" compatibility. 100% protection against the 100 year event shows to be the optimal degree of protection. Consequently, impacts statistically less frequent than once in 100 year are accepted as the remaining risk. Such floods and debris flows respectively cause a fan of propagation which is substantially reduced due to the protection measures against the 100 year event. III) The "triple loss distribution" shows the monetized triple damage, dependent on its probability. The monetization is performed by the social process of participation of the impacted interests, if not, by official experts in representation. The triple loss distribution rises in time mainly due to the rise in density and value of precious goods. A comparison of the distributions of the triple loss and the triple risk, behaving in opposite direction, is shown and explained within the project. IV) The recommended yearly reserves to be stocked for restoration and compensation of losses, caused by debris flows, amount to € 70'000.- according to the approach of the "technical risk premium". The discrepancy in comparison with the much higher amounts according to the common approaches of natural hazards engineering are discussed. V) The sustainable mix of hydraulic and forestry measures with the highest return on investment at lowest risk is performed according to the portfolio theory (Markowitz), based on the triple value curves, generated by the method of TripelBudgetierungź. Accordingly, the optimum mix of measures to protect the community of Inzing against the natural hazard of debris flow, thus, the most efficient allocation of resources equals to 2/3 for hydraulic, 1/3 for forestry measures. In detail, the results of the research pilot project "Nachhaltiges Risikomanagement - Enterbach / Inzing / Tirol / Austria" may be consulted under www.ibu.hsr.ch/inzing.

  10. Randomized controlled trials in evidence-based mental health care: getting the right answer to the right question.

    PubMed

    Essock, Susan M; Drake, Robert E; Frank, Richard G; McGuire, Thomas G

    2003-01-01

    The purpose of clinical research is to answer this question: Would a new treatment, when added to the existing range of treatment options available in practice, help patients? Randomized controlled trials (RCTs)--in particular, double-blind RCTs--have important methodological advantages over observational studies for addressing this question. These advantages, however, come at a price. RCTs compare treatments using a particular allocation rule for assigning patients to treatments (random assignment) that does not mimic real-world practice. "Favorable" results from an RCT indicating that a new treatment is superior to existing treatments are neither necessary nor sufficient for establishing a "yes" answer to the question posed above. Modeled on an experimental design, RCTs are expensive in time and money and must compare simple differences in treatments. Findings have a high internal validity but may not address the needs of the field, particularly where treatment is complex and rapidly evolving. Design of clinical research needs to take account of the way treatments are allocated in actual practice and include flexible designs to answer important questions most effectively. PMID:12908666

  13. What are Middle School Students Talking About During Clicker Questions? Characterizing Small-Group Conversations Mediated by Classroom Response Systems

    NASA Astrophysics Data System (ADS)

    Barth-Cohen, Lauren A.; Smith, Michelle K.; Capps, Daniel K.; Lewin, Justin D.; Shemwell, Jonathan T.; Stetzer, MacKenzie R.

    2016-02-01

    There is a growing interest in using classroom response systems or clickers in science classrooms at both the university and K-12 levels. Typically, when instructors use this technology, students are asked to answer and discuss clicker questions with their peers. The existing literature on using clickers at the K-12 level has largely focused on the efficacy of clicker implementation, with few studies investigating collaboration and discourse among students. To expand on this work, we investigated the question: Does clicker use promote productive peer discussion among middle school science students? Specifically, we collected data from middle school students in a physical science course. Students were asked to answer a clicker question individually, discuss the question with their peers, answer the same question again, and then subsequently answer a new matched-pair question individually. We audio recorded the peer conversations to characterize the nature of the student discourse. To analyze these conversations, we used a grounded analysis approach and drew on literature about collaborative knowledge co-construction. The analysis of the conversations revealed that middle school students talked about science content and collaboratively discussed ideas. Furthermore, the majority of conversations, both ones that positively and negatively impacted student performance, contained evidence of collaborative knowledge co-construction.

This manuscript addresses frequently asked questions by patients with HPV-OSCC and their families. A framework for clinicians to address these conversations and the limitations of our present knowledge base is also presented. PMID:23876627

  16. Asking a Great Question: A Librarian Teaches Questioning Skills to First-Year Medical Students.

    PubMed

    Adams, Nancy E

    2015-01-01

    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.

    In this article the answers provided by 98, 12-year-old students to questions included in an end-of-year science examination are analysed. Almost all of the students are able to explain day and night, but the reason why the Moon always presents the same face to the Earth is less well understood. Estimations of the time in Earth days from sunrise to sunrise on the Moon vary. Most students can explain the apparent movement of stars across the night-sky, but their direction is less certain. Implications of the findings for teaching and learning are addressed.

    Smith, M.K.; Wood, W.B.; Krauter, K.; Knight, J.K.

    2011-01-01

    Use of in-class concept questions with clickers can transform an instructor-centered “transmissionist” environment to a more learner-centered constructivist classroom. To compare the effectiveness of three different approaches using clickers, pairs of similar questions were used to monitor student understanding in majors’ and nonmajors’ genetics courses. After answering the first question individually, students participated in peer discussion only, listened to an instructor explanation only, or engaged in peer discussion followed by instructor explanation, before answering a second question individually. Our results show that the combination of peer discussion followed by instructor explanation improved average student performance substantially when compared with either alone. When gains in learning were analyzed for three ability groups of students (weak, medium, and strong, based on overall clicker performance), all groups benefited most from the combination approach, suggesting that peer discussion and instructor explanation are synergistic in helping students. However, this analysis also revealed that, for the nonmajors, the gains of weak performers using the combination approach were only slightly better than their gains using instructor explanation alone. In contrast, the strong performers in both courses were not helped by the instructor-only approach, emphasizing the importance of peer discussion, even among top-performing students. PMID:21364100

    2016-03-01

    Readers with autism (ASD), poor comprehension (PC), and typical development (TD) took part in three reading experiments requiring the production of inferences. In Experiments 1 and 2 reading times for target phrases-placed immediately after text implicitly indicating the emotion of a protagonist or after a number of filler sentences, respectively-were used as measures of inferencing. In Experiment 3, participants were explicitly asked to identify the protagonist's emotion. There were no significant differences among groups in Experiment 1. Compared to TD readers, the PC group performed poorly in Experiments 2 and 3. ASD readers performed worse than PC participants only in the explicit-question task. Although ASD readers can produce inferences, they respond to questions about them with difficulty. PMID:26547920

    2011-01-01

    Summary Adult neurogenesis, a process of generating functional neurons from adult neural precursors, occurs throughout life in restricted brain regions in mammals. The past decade has witnessed tremendous progress in addressing questions related to almost every aspect of adult neurogenesis in the mammalian brain. Here we review major advances in our understanding of adult mammalian neurogenesis in the dentate gyrus of the hippocampus and from the subventricular zone of the lateral ventricle, the rostral migratory stream to the olfactory bulb. We highlight emerging principles that have significant implications for stem cell biology, developmental neurobiology, neural plasticity, and disease mechanisms. We also discuss remaining questions related to adult neural stem cells and their niches, underlying regulatory mechanisms and potential functions of newborn neurons in the adult brain. Building upon the recent progress and aided by new technologies, the adult neurogenesis field is poised to leap forward in the next decade. PMID:21609825

    Nitrate levels in the ground-water aquifer underlying the central Oregon city of La Pine and the surrounding area are increasing due to contamination from residential septic systems. This contamination has public health implications because ground water is the sole source of drinking water for area residents. The U.S. Geological Survey, in cooperation with Deschutes County and the Oregon Department of Environmental Quality, studied the movement and chemistry of nitrate in the aquifer and developed computer models that can be used to predict future nitrate levels and to evaluate alternatives for protecting water quality. This fact sheet summarizes the results of that study in the form of questions and answers.

    Medical professionals frequently face unmet information needs during their daily routines. We investigated the use of web search engines through a large-scale survey including 500 European physicians, as well as local user testing that observed the search behavior of physicians when facing clinical questions. We identified several differences in the search requirements and behaviors of different groups of physicians based on level of qualification and level of specialization. We also found user testing a valuable source of information about the search preferences of medical professional. The survey and user tests we conducted are among the largest and most detailed that have been conducted in this domain. PMID:23920877

    Data fitting and model selection lie at the very heart of the scientific method, and these tasks are often tackled via the use of popular (and typically unquestioned) optimization algorithms of limited validity or flexibility, e.g., least-squares methods. To circumvent these limitations, this work introduces the implementation within the MANTID framework of robust inference methods based on the Bayesian fitting algorithm FABADA. The power of this new MANTID tool is illustrated by revisiting an overarching and recurring question in the interpretation of quasielastic neutron scattering measurements, that is, how many spectral components may (or may not) be justified by the available experimental data.

  16. Questions and answers about the effects of the depletion of the ozone layer on humans and the environment.

    PubMed

    Aucamp, Pieter J

    2007-03-01

    The ozone molecule contains three atoms of oxygen and is mainly formed by the action of the ultraviolet rays of the sun on the diatomic oxygen molecules in the upper part of the Earth's atmosphere (called the stratosphere). Atmospheric pollution near the Earth's surface can form localized areas of ozone. The stratospheric ozone layer protects life on Earth by absorbing most of the harmful ultraviolet radiation from the sun. In the mid 1970s it was discovered that some manmade products destroy ozone molecules in the stratosphere. This destruction can result in damage to ecosystems and to materials such as plastics. It may cause an increase in human diseases such as skin cancers and cataracts. The discovery of the role of the synthetic ozone-depleting chemicals such as chlorofluorocarbons (CFCs) stimulated increased research and monitoring in this field. Computer models predicted a disaster if no action was taken to protect the ozone layer. Based on this research and monitoring, the nations of the world took action in 1985 with the Vienna Convention for the Protection of the Ozone Layer followed by the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. The Convention and Protocol were amended and adjusted several times as new knowledge was obtained. The Meetings of the Parties to the Montreal Protocol appointed three Assessment Panels to review the progress in scientific knowledge on their behalf. These panels are the Scientific Assessment Panel, the Technological and Economic Assessment Panel and the Environmental Effects Assessment Panel. Each panel covers a designated area and there is a natural level of overlap. The main reports of the Panels are published every four years as required by the Meeting of the Parties. All the reports have an executive summary that is distributed more widely than the main report itself. It became customary to add a set of questions and answers--mainly for non-expert readers--to the executive summaries. This document contains the questions and answers prepared by experts who comprise the Environmental Assessment Panel. It is based mainly on the 2006 report of the Panel but also contains information from previous assessments. Readers who need detailed information on any question should consult the full reports for a more complete scientific discussion. This set of questions refers mainly to the environmental effects of ozone depletion and climate change. The report of the Scientific Assessment Panel contains questions and answers related to the other scientific issues addressed by that Panel. All these reports can be found on the UNEP website (http://ozone.unep.org). PMID:17344966

    PubMed

    Reynolds, Kristin A; Walker, John R; Walsh, Kate

    2015-10-01

    The goals of this study were to evaluate the quality of information concerning anxiety disorders in children that is available on the Internet and to evaluate changes in the quality of website information over time. The authors identified websites addressing child anxiety disorders (N = 26) using a Google search and recommendations from an expert in child anxiety. Each website was evaluated on the extent to which it addressed questions that parents consider important, the quality of information, and the reading level. All websites provided adequate information describing treatment options; however, fewer websites had information addressing many questions that are important to parents, including the duration of treatment, what happens when treatment stops, and the benefits and risks of various treatments. Many websites provided inadequate information on pharmacological treatment. Most websites were of moderate quality and had more difficult reading levels than is recommended. Five years after the initial assessment, authors re-analyzed the websites in order to investigate changes in content over time. The content of only six websites had been updated since the original analysis, the majority of which improved on the three aforementioned areas of evaluation. Websites could be strengthened by providing important information that would support parent decision-making. PMID:24830663

  19. Floral morphology and structure of Emblingia calceoliflora (Emblingiaceae, Brassicales): questions and answers.

    PubMed

    Tobe, Hiroshi

    2015-05-01

    Emblingia calceoliflora, the sole species of the family Emblingiaceae (Brassicales), is a creeping shrub endemic to South Western Australia. The flowers have a characteristic slipper-like corolla (calceolus). Earlier studies using dry specimens have left some questions regarding the flower unresolved. Here I present an anatomical study of fresh flowers to resolve these questions. The flowers are pedicellate, strongly monosymmetric, and pentamerous with the median sepal in the abaxial position. During flower development, a pedicel turns clockwise or anticlockwise, placing the adaxial calceolus (comprising both petals) downward and a transversely dilated androgynophore upward with a large tunnel-like space between them. Two short longitudinal walls develop from the basal part of the petals, enclosing a nectary gland deep in the flower. The vascular anatomy of the androgynophore shows that lateral dédoublement occurs in five stamens, resulting in two pairs of fertile stamens on the adaxial side and (three to) six staminodes as the "hood" on the opposite side. Androecial configuration is obhaplostemony, and the gynoecium is tricarpellate/trilocular. Comparisons with flowers of other Brassicales show that an extrastaminal nectary is a synapomorphy of the core Brassicales including Emblingiaceae. The flower of Emblingia is highly specialized for adaptation to insect-pollination. PMID:25666829

    Systematic reviews assist nurses, other health care providers, decision makers, and consumers in managing the explosion of health care information by synthesizing valid data and reporting the effects of interventions. Nurses are increasingly using systematic reviews to guide their practice and develop policy. The purpose of the article is to outline the steps involved in conducting a systematic review with examples taken from a systematic review titled "Strategies to Manage the Behavioral Symptoms Associated With Alzheimer's Disease." The steps of a systematic review include: (a) formulating a well-defined question, (b) developing relevance and validity tools, (c) conducting a comprehensive search to retrieve published and unpublished reports, (d) assessing the reports using relevance and validity tools, (e) data extraction, (f) synthesis of the findings, and (g) report writing. Understanding the steps involved in a systematic review will assist nurses in critically appraising reviews and in conducting their own reviews. PMID:12666642

    PubMed Central

    Blagosklonny, Mikhail V.

    2012-01-01

    Recent discoveries suggest that aging is neither driven by accumulation of molecular damage of any cause, nor by random damage of any kind. Some predictions of a new theory, quasi-programmed hyperfunction, have already been confirmed and a clinically-available drug slows aging and delays diseases in animals. The relationship between diseases and aging becomes easily apparent. Yet, the essence of aging turns out to be so startling that the theory cannot be instantly accepted and any possible arguments are raised for its disposal. I discuss that these arguments actually support a new theory. Are any questions remaining? And might accumulation of molecular damage still play a peculiar role in aging? PMID:23425777

    The association between hearing impairment, the diagnosis of dementia, and the role of sensory therapy has been proposed for some time, but further research is needed. Current understanding of this association requires the commitment of those experts who can integrate experience and research from several fields to be able to understand the link from hearing to dementia. A workshop whose panelists included experts from many areas, ranging from ear, nose and throat (ENT) to dementia's specialists, was promoted and organized by the Giovanni Lorenzini Medical Science Foundation (Milan, Italy; Houston, TX, USA) to increase the awareness of the relationship between hearing loss and dementia, and included questions and comments following a presentation from the clinical researcher, Frank Lin, who has been evaluating the relationship between hearing loss and cognitive decline since 2009.

Great progress has been made in understanding the biology of PAPP-A and its regulation during recent years, especially in regard to physiological and pathophysiological inflammatory injury responses. But much remains to be learned about this complex protein and its potential clinical implications outside of pregnancy. In this article we address some of the outstanding questions about PAPP-A, in particular about its newly emerging role in the insulin-like growth factor (IGF) system. PMID:22463950

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

    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 questioning. This data should be shared with teachers and teacher educators to inform them how to increase and use student questions as well as alternate participation methods that strive for "science for all". Future research should focus on how students act as "gatekeepers" for the participation and potential ways to shift underrepresented students into the STEM pipeline.

  10. Treatment of burns in the first 24 hours: simple and practical guide by answering 10 questions in a step-by-step form

    PubMed Central

    2012-01-01

    Residents in training, medical students and other staff in surgical sector, emergency room (ER) and intensive care unit (ICU) or Burn Unit face a multitude of questions regarding burn care. Treatment of burns is not always straightforward. Furthermore, National and International guidelines differ from one region to another. On one hand, it is important to understand pathophysiology, classification of burns, surgical treatment, and the latest updates in burn science. On the other hand, the clinical situation for treating these cases needs clear guidelines to cover every single aspect during the treatment procedure. Thus, 10 questions have been organised and discussed in a step-by-step form in order to achieve the excellence of education and the optimal treatment of burn injuries in the first 24 hours. These 10 questions will clearly discuss referral criteria to the burn unit, primary and secondary survey, estimation of the total burned surface area (%TBSA) and the degree of burns as well as resuscitation process, routine interventions, laboratory tests, indications of Bronchoscopy and special considerations for Inhalation trauma, immediate consultations and referrals, emergency surgery and admission orders. Understanding and answering the 10 questions will not only cover the management process of Burns during the first 24 hours but also seems to be an interactive clear guide for education purpose.

  11. A text of two titles: Kant's 'A renewed attempt to answer the question: "is the human race continually improving"?

    PubMed

    Zammito, John H

    2008-12-01

    The essay, 'A renewed attempt to answer the question: "Is the human race continually improving?"' appeared as Part II of Kant's 1798 publication, The conflict of the faculties, where it was subordinated under a second title: 'The conflict of the philosophy faculty with the faculty of law'. How did this new situation (and title) affects the meaning of the essay? My argument considers first, the conflict of the faculty of philosophy with the faculty of law; second, the earlier philosophy of history Kant had developed; and, finally, the revision of this position in 'A renewed attempt'. The situation of his argument in the contest between the philosophical and the legal faculties points to other veins of argumentation in Kant's political theory, particularly his appeal to a principle of publicity, but they hardly achieve the theoretical clarity or the systematic centrality they should command. They are displaced in the quest for prediction of the future history of mankind. The question of human progress exceeds the frame of the coordination of the university, and the main question must remain: what was new in Kant's approach to the question of human progress, and was it in fact an enhancement of his philosophy of history? In those terms, 'A renewed attempt' must be regarded a distinct failure. Its innovations prove problematic. Its retreats and equivocations, moreover, threaten to undermine the grander vision of Kant's philosophical history and his political theory, entangling them in an unacceptably theological recourse.

    This case study investigated gender-based differences in classroom participation through examining teacher-student interactions between a female biology teacher and two groups of middle school students, namely high achievers and low achievers. The female teacher used a questioning-orientated instructional strategy as her major teaching style which creates greater opportunities for student participation in biology learning. Classroom sessions were videotaped for one school year, then analysed for gender differences in question-and-answer patterns. The results showed that more teacher-initiated questions, teacher-directed interactions, and teacher feedback were given to males than females in both groups, but a large difference was found between the two groups of students. Girls in the low-achieving biology class (LABC) were more likely to participate at a rate comparable with their male classmates; girls answered more procedure questions and an equal percentage of process questions, called out approximately the same percentage of answers to undirected teacher-initiated questions, and received more instances of praise and follow-up questions. Contrary to what was observed in the high-achieving biology class (HABC), LABC girls initiated more questions than LABC boys.

    2013-11-01

    With the release of the updated pain, agitation, and delirium guidelines by the Society of Critical Care Medicine, a number of new and updated recommendations are provided regarding the pharmacological prevention and treatment of ICU delirium. Whereas this is important to understand the limitations of existing literature in interpreting the guideline recommendations, it also provides an opportunity to identify those areas of practice where we need further knowledge. We discuss 5 of the most critical questions in our view regarding pharmacological therapy for ICU delirium in an attempt to highlight areas of this ICU condition that are much deserving of further research, including the deliriogenic potential of dexmedetomidine, optimal sedative choices for the delirious ICU patient, pharmacological prophylaxis for ICU delirium, optimal treatment duration for ICU delirium, and the impact of pharmacotherapy on long-term cognitive outcomes in ICU survivors. A multitude of opportunities for further research exist in the above areas for clinicians and researchers interested in this ICU condition. PMID:24285768

    ALAT-2014 COPD Clinical Practice Guidelines used clinical questions in PICO format to compile evidence related to risk factors, COPD screening, disease prognosis, treatment and exacerbations. Evidence reveals the existence of risk factors for COPD other than tobacco, as well as gender differences in disease presentation. It shows the benefit of screening in an at-risk population, and the predictive value use of multidimensional prognostic indexes. In stable COPD, similar benefits in dyspnea, pulmonary function and quality of life are achieved with LAMA or LABA long-acting bronchodilators, whereas LAMA is more effective in preventing exacerbations. Dual bronchodilator therapy has more benefits than monotherapy. LAMA and combination LABA/IC are similarly effective, but there is an increased risk of pneumonia with LABA/IC. Data on the efficacy and safety of triple therapy are scarce. Evidence supports influenza vaccination in all patients and anti-pneumococcal vaccination in patients <65years of age and/or with severe airflow limitation. Antibiotic prophylaxis may decrease exacerbation frequency in patients at risk. The use of systemic corticosteroids and antibiotics are justified in exacerbations requiring hospitalization and in some patients managed in an outpatient setting. PMID:25596991

    2014-01-01

    The maxilliped venom claw is an intriguing structure in centipedes. We address open questions concerning this structure. The maxillipeds of fossil centipedes from the Carboniferous (about 300 million years old) have been described, but not been depicted previously. Re-investigation demonstrates that they resemble their modern counterparts. A Jurassic geophilomorph centipede (about 150 million years old) was originally described as possessing a rather leg-like maxilliped. Our re-investigation shows that the maxilliped is, in fact, highly specialized as in modern Geophilomorpha. A scenario for the evolution of the centipede maxilliped is presented. It supports one of the two supposed hypotheses of centipede phylogeny, the Pleurostigmophora hypothesis. Although this hypothesis appears now well established, many aspects of character evolution resulting from this phylogeny remain to be told in detail. One such aspect is the special joint of the maxilliped in some species of Cryptops. Cryptops is an in-group of Scolopendromorpha, but its maxilliped joint can resemble that of Lithobiomorpha or even possess a mixture of characters between the both. Detailed investigation of fossils, larger sample sizes of extant species, and developmental data will be necessary to allow further improvements of the reconstruction of the evolutionary history of centipedes.

    Cardiac troponin (cTn) assays have quickly gained in analytical sensitivity to become what are termed 'high-sensitivity cardiac troponin' (hs-cTn) assays, bringing a flurry of dense yet incomplete literature data. The net result is that cTn assays are not yet standardized and there are still no consensus-built data on how to use and interpret cTn assay results. To address these issues, the authors take cues and clues from multiple disciplines to bring responses to frequently asked questions. In brief, the effective use of hs-cTn hinges on knowing: specific assay characteristics, particularly precision at the 99th percentile of a reference population; factors of variation at the 99th percentile value; and the high-individuality of hs-cTn assays, for which the notion of individual kinetics is more informative than straight reference to 'normal' values. The significance of patterns of change between two assay measurements has not yet been documented for every hs-cTn assay. Clinicians need to work hand-in-hand with medical biologists to better understand how to use hs-cTn assays in routine practice. PMID:25669958

  20. Cajal's prophetic functional considerations on respiratory reflexes: new questions about old answers.

    PubMed

    2002-01-01

    In the "Histology of the Nervous System" (Histologie, Spanish edition, 1899, 1904; French translation, 1909, 1911; all citations are from the American translation, 1995) Cajal did not only describe the origins and central pathways of cranial nerves but his detailed observations led him to numerous conclusions about the functional organization of brainstem reflexes. From studies of vagal and glossopharyngeal afferents he proposed a structural organization of the nucleus tractus solitarii (NTS). His view has been considerably changed by several authors on the basis of modern tracing studies. However, detailed histological examinations of functionally identified sensory fibers provided new understanding of a functional organization of the solitary nucleus that is very well in line with Cajal's original descriptions. The prophetic character of Cajal's concepts of structural-functional relations becomes even more evident by a reconsideration of his explanations of the reflexes underlying respiration, coughing and vomiting. Recent electrophysiological studies of spontaneously rhythmically active in vitro preparations have provided us with new insights in respiratory control. However, it appears that quite a number of Cajal's key questions concerning respiratory reflexes are still not solved. Therefore, a reconsideration of old and partly forgotten concepts might indeed provide a novel understanding of the structural and functional organization of brainstem reflexes. PMID:12143400

    The increase in surface temperature of the Earth indicates a lower risk of exposure for temperate grassland and crop to extremely low temperatures. However, the risk of low winter survival rate, especially in higher latitudes may not be smaller, due to complex interactions among different environmental factors. For example, the frequency, degree and length of extreme winter warming events, leading to snowmelt during winter increased, affecting the risks of anoxia, ice encasement and freezing of plants not covered with snow. Future climate projections suggest that cold acclimation will occur later in autumn, under shorter photoperiod and lower light intensity, which may affect the energy partitioning between the elongation growth, accumulation of organic reserves and cold acclimation. Rising CO2 levels may also disturb the cold acclimation process. Predicting problems with winter pathogens is also very complex, because climate change may greatly influence the pathogen population and because the plant resistance to these pathogens is increased by cold acclimation. All these factors, often with contradictory effects on winter survival, make plant overwintering viability under future climates an open question. Close cooperation between climatologists, ecologists, plant physiologists, geneticists and plant breeders is strongly required to predict and prevent possible problems. PMID:25017157

    PubMed

    1993-07-01

    The size of national health care expenditure is an important research and policy issue. This paper reviews theoretical and empirical analyses of an implied optimal size for a health sector. Various economic theories are explicitly or implicitly invoked, but none is fully satisfactory. Theory provides, at best, a loose justification for empirical specifications of health sector behaviour. Nevertheless, this has a large and growing empirical research industry. The complexity of the issues provides an excuse for reliance on empirical analyses using ad hoc models. The paper analyses aggregate time-series data, using the cointegration approach, on health, health care expenditures and national income. Only one national model met both statistical criteria and showed a significant relationship: between potential life years lost and health care expenditure in the UK. The case for any general relationships remains unproven. There is no objective scientific method to determine optimal health expenditure, nor should we expect one. However, positive analyses can help with normative questions. A better understanding of health expenditure determination would arise from better specification of the relationships, perhaps by analysis at a lower level of aggregation. PMID:8261033

    2014-12-01

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

  5. Moving from answer finding to sensemaking: Supporting middle school students' online inquiry

    NASA Astrophysics Data System (ADS)

    Zhang, Meilan

    Online inquiry, use of the Web as an information source to conduct inquiry for a scientific question, has become increasingly common in middle schools in recent years. However, while valuable Web resources provide unprecedented learning opportunities, easy access to information does not guarantee learning. Previous research has found that middle school students tend to use the Web in a superficial manner. To address the challenges that students face in online inquiry, this study explored several supporting strategies implemented in Digital IdeaKeeper, a scaffolded software tool to help students move from passively finding a ready-made answer to actively making sense of the information they encounter through support for inquiry planning, information search, analysis, and synthesis. This study examined the differences and similarities between regular online inquiry and supported online inquiry performed by several sixth-graders in real classroom settings. Four pairs from a sixth grade class used IdeaKeeper for their online inquiry project, and another four pairs from a different sixth grade class taught by the same teacher used regular online search engines only. Both groups worked on the same science topic-water, and the entire project lasted about four weeks. During that time, students in both groups used computers for about 10-14 days to conduct online research. Multiple sources of data were collected, including video recordings of students' computer activities and conversations, students' artifacts, log files and student final writings. Several themes emerged from the data analysis. First, the findings refer to the importance of providing a structure for students' online inquiry, to promote a more integrated, efficient, continuous, metacognitive and engaging online inquiry. In addition, guidance is important to promote more careful, thorough, and purposeful online reading, Overall, the results suggest that middle school students' online inquiry needs to be structured and their online reading needs to be guided. However, challenges still remain to engage students in high-level critical thinking in online inquiry, because some prompts designed to guide students' reading do not seem effective. Implications of the research findings are discussed.

  6. Eye Tracking Research to Answer Questions about Augmentative and Alternative Communication Assessment and Intervention

    2015-01-01

    Recently, eye tracking technologies (i.e., technologies that automatically track the point of an individual’s gaze while that person views or interacts with a visual image) have become available for research purposes. These technologies record the orientation of the individual’s eyes in a series of samples taken at rapid intervals through measurement of infrared light reflected from the cornea (the curved portion of the eyeball) and the pupil, and as a function of the distance of the eyes from the monitor. Based on the sampling information, researchers can quantify which locations within the visual image were fixated (viewed), for how long, and how many times. These automated eye tracking technologies open up a wealth of avenues for investigating how individuals with developmental or acquired communication disabilities may respond to aided augmentative and alternative communication (AAC) systems. In this paper, we introduce basic terminology and summarize some of the considerations of importance to researchers seeking to do this type of research. We also explore some of the special challenges of conducting eye tracking research with populations with disabilities who might use AAC, including challenges of inferring attention from the presence of fixation and challenges related to calibration that may result from participant characteristics, behavioral idiosyncracies, and/or the number of calibration points. We also examine how the technology can be applied to ask well-structured experimental questions that have direct clinical relevance, with a focus on the unique contributions that eye tracking research can provide by (a) allowing evaluation of skills in individuals who are difficult to assess via traditional methods and (b) facilitating access to information on underlying visual cognitive processes that is not accessible via traditional behavioral measures.

The TCDT provides the crew with emergency egress training, opportunities to inspect their mission payloads in the orbiter's payload bay, and simulated countdown exercises. STS-103 is a 'call-up' mission due to the need to replace and repair portions of the Hubble Space Telescope, including the gyroscopes that allow the telescope to point at stars, galaxies and planets. The STS-103 crew will be replacing a Fine Guidance Sensor, an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The mission is targeted for launch Dec. 6 at 2:37 a.m. EST.

    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 the research was 'an invaluable experience.' Conceptual models of QUEST's philosophy will be distributed at our presentation to encourage audience members interested in starting their own field-based educator professional development project. Through our presentation of this unique program, we will share how we have successfully incorporated real scientific research into classrooms through teachers' experiences, and discuss the lessons learned regarding replication and sustainability of educator-scientist collaborations.
