  1. Basic Physics Questions Addressed by Astrophysics

    Mather, John C.

    2009-01-01

    Dark matter, dark energy, the Big Bang, testing relativity -- all are physics questions accessible to astrophysicists -- but all require new equipment. As Harwit's "Cosmic Discovery" pointed out, almost all great surprises in astronomy came from new equipment or new uses of equipment designed for other purposes, and many of those had military applications. I will outline prospects for new equipment and discuss how that equipment can be developed and built. Bigger and lighter mirrors, wavefront sensing and control, new detector technology, cryogenics -- each has its own social network, its own special possibilities, and its own funding sources outside science. I will discuss some examples drawn from real-life experience with the James Webb Space Telescope, a telescope that was said to have a "giggle factor" when it was proposed in 1995. Now each of the 10 major technologies has been brought to maturity, flight hardware is being built, and launch is planned for 2014. As an instrument builder all my life, I will speculate a little on what may be within our reach over the next few decades.

  6. Dynamic Question Ordering in Online Surveys

    2017-09-01

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

  7. Addressing the Question of Homophobia in Jordanian Public Discourse

    2016-11-01

    Full Text Available This article investigates the question of homosexuality, homosexuals, and homophobia in the Jordanian public debate in the aftermath of an LGBTQIA meeting that was held secretly in Amman in May 2015. The main purpose of the article is to demonstrate the constituents and arguments which reproduce the public discourse on anti-homosexuality and anti-homosexuals and homophobia in Jordan. This purpose is reached by analysing 35 journal articles written in Standard Arabic in Jordanian public and open-access media. The analysis involves the qualitative analysis of the argument, processes, and themes used to represent homosexuality and homosexuals by the discourse producers. The analysis reveals that the question of homosexuality and homosexuals in Jordan can be addressed in terms of seven angles: the public anti-homosexuality and anti-homosexuals’ calls, the (Islamic religious argument, protecting and reinforcing law and order, the argument of (homosexually-transmitted diseases, the calls of pro-homosexuality and pro-homosexuals and LGBTQIA’s rights activists, the homosexuals’ own self-representation, and the neutral scientific account and representation.

    An increasing number of network observatories have been established globally to collect long-term biogeochemical data at multiple spatial and temporal scales. Although many outstanding questions in biogeochemistry would benefit from network science, the ability of the earth- and environmental-sciences community to conduct synthesis studies within and across networks is limited and seldom done satisfactorily. We identify the ideal characteristics of networks, common problems with using data, and key improvements to strengthen intra- and internetwork compatibility. We suggest that targeted improvements to existing networks should include promoting standardization in data collection, developing incentives to promote rapid data release to the public, and increasing the ability of investigators to conduct their own studies across sites. Internetwork efforts should include identifying a standard measurement suite—we propose profiles of plant canopy and soil properties—and an online, searchable data portal that connects network, investigator-led, and citizen-science projects.

  10. Incomplete categorical data design non-randomized response techniques for sensitive questions in surveys

    2013-01-01

    Respondents to survey questions involving sensitive information, such as sexual behavior, illegal drug usage, tax evasion, and income, may refuse to answer the questions or provide untruthful answers to protect their privacy. This creates a challenge in drawing valid inferences from potentially inaccurate data. Addressing this difficulty, non-randomized response approaches enable sample survey practitioners and applied statisticians to protect the privacy of respondents and properly analyze the gathered data.Incomplete Categorical Data Design: Non-Randomized Response Techniqu

    Survey designers have long assumed that respondents who disagree with a negative question ("This policy is bad.": "Yes" or "No"; 2-point scale) will agree with an equivalent positive question ("This policy is good.": "Yes" or "No"; 2-point scale). However, experimental evidence has proven otherwise: Respondents are more likely to disagree with…

    Chandra, AM

    2005-01-01

    The book provides a lucid and step-by-step treatment of the various principles and methods for solving problems in land surveying. Each chapter starts with basic concepts and definitions, then solution of typical field problems and ends with objective type questions. The book explains errors in survey measurements and their propagation. Survey measurements are detailed next. These include horizontal and vertical distance, slope, elevation, angle, and direction. Measurement using stadia tacheometry and EDM are then highlighted, followed by various types of levelling problems. Traversing is then explained, followed by a detailed discussion on adjustment of survey observations and then triangulation and trilateration.

    2016-07-01

    Full Text Available Question answering systems (QASs generate answers of questions asked in natural languages. Early QASs were developed for restricted domains and have limited capabilities. Current QASs focus on types of questions generally asked by users, characteristics of data sources consulted, and forms of correct answers generated. Research in the area of QASs began in 1960s and since then, a large number of QASs have been developed. To identify the future scope of research in this area, the need of a comprehensive survey on QASs arises naturally. This paper surveys QASs and classifies them based on different criteria. We identify the current status of the research in the each category of QASs, and suggest future scope of the research.

  17. Addressing challenges to MMPI-2-RF-based testimony: questions and answers.

    Science.gov (United States)

    Ben-Porath, Yossef S

    2012-11-01

    Introduction of a new version of a psychological test brings with it challenges that can be accentuated by the adversarial nature of the legal process. In the case of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), these challenges can be addressed by becoming familiar with the rationale for and the methods used in revising the inventory, the information contained in the test manuals, and the growing peer-reviewed literature on the test. Potential challenges to MMPI-2-RF-based testimony are identified in this article and discussed in question and answer format. The questions guiding this discussion are based on the Daubert factors, established in 1993 by the US Supreme Court as criteria for gauging the scientific validity of proffered expert testimony. The answers to these questions apply more broadly to testimony in depositions, pre-trial hearings, and at trial. Consideration of the MMPI-2-RF in light of the Daubert factors indicates that the instrument has been subjected to extensive empirical testing and that a substantial peer-reviewed literature is available to guide and support its use. Information about the known and potential rate of error associated with MMPI-2-RF scores is available, and standard procedures for administration, scoring, and interpretation of the inventory are detailed in the test administration manual. Indicators of MMPI-2-RF acceptance can be cited, and criticisms of the MMPI-2-RF can be addressed with information available in the test documents and an extensive, modern, and actively growing peer-reviewed literature.

  18. Addressing Tobacco in Managed Care: Results of the 2002 Survey

    Directory of Open Access Journals (Sweden)

    Carol McPhillips-Tangum

    2004-10-01

    Full Text Available Introduction In the United States, tobacco use is the leading preventable cause of death and disease. The health and cost consequences of tobacco dependence have made treatment and prevention of tobacco use a key priority among multiple stakeholders, including health plans, insurers, providers, employers, and policymakers. In 2002, the third survey of tobacco control practices and policies in health plans was conducted by America’s Health Insurance Plans’ technical assistance office as part of the Addressing Tobacco in Managed Care (ATMC program. Methods The ATMC survey was conducted in the spring of 2002 via mail, e-mail, and fax. A 19-item survey instrument was developed and pilot-tested. Of the 19 items, 12 were the same as in previous years, four were modified to collect more detailed data on areas of key interest, and three were added to gain information about strategies to promote smoking cessation. The sample for the survey was drawn from the 687 plans listed in the national directory of member and nonmember health plans in America's Health Insurance Plans. Results Of the 246 plans in the sample, 152 plans (62% representing more than 43.5 million health maintenance organization members completed the survey. Results show that health plans are using evidence-based programs and clinical guidelines to address tobacco use. Compared to ATMC survey data collected in 1997 and 2000, the 2002 ATMC survey results indicate that more health plans are providing full coverage for first-line pharmacotherapies and telephone counseling for smoking cessation. Plans have also shown improvement in their ability to identify at least some members who smoke. Similarly, a greater percentage of plans are employing strategies to address smoking cessation during the postpartum period to prevent smoking relapse and during pediatric visits to reduce or eliminate children’s exposure to environmental tobacco smoke. Conclusion The results of the 2002 ATMC survey

  20. A meta-analysis of personality and workplace safety: addressing unanswered questions.

    [Correction Notice: An Erratum for this article was reported in Vol 100(2) of Journal of Applied Psychology (see record 2015-08139-001). Table 3 contained formatting errors. Minus signs used to indicate negative statistical estimates within the table were inadvertently changed to m-dashes. All versions of this article have been corrected.] The purpose of this meta-analysis was to address unanswered questions regarding the associations between personality and workplace safety by (a) clarifying the magnitude and meaning of these associations with both broad and facet-level personality traits, (b) delineating how personality is associated with workplace safety, and (c) testing the relative importance of personality in comparison to perceptions of the social context of safety (i.e., safety climate) in predicting safety-related behavior. Our results revealed that whereas agreeableness and conscientiousness were negatively associated with unsafe behaviors, extraversion and neuroticism were positively associated with them. Of these traits, agreeableness accounted for the largest proportion of explained variance in safety-related behavior and openness to experience was unrelated. At the facet level, sensation seeking, altruism, anger, and impulsiveness were all meaningfully associated with safety-related behavior, though sensation seeking was the only facet that demonstrated a stronger relationship than its parent trait (i.e., extraversion). In addition, meta-analytic path modeling supported the theoretical expectation that personality's associations with accidents are mediated by safety-related behavior. Finally, although safety climate perceptions accounted for the majority of explained variance in safety-related behavior, personality traits (i.e., agreeableness, conscientiousness, neuroticism) still accounted for a unique and substantive proportion of the explained variance. Taken together, these results substantiate the value of considering personality traits as key

  1. How the question of innovation is addressed by the social sciences

    Jean Corneloup

    2009-07-01

    Full Text Available Although innovation has today become a topical notion, given its fundamental importance in understanding the economy and the way our society adapts to its development goals, its characteristics and principles nevertheless need to be defined. While the 20th century was marked by important technological, political, economic and cultural changes, the current era seems to be increasingly bent on imposing innovation as a motor for the development of society. It is therefore important to understand how the question of innovation is currently being addressed, and in turn this involves looking at the different ways in which the innovative process is interpreted. Between the notional approach, which often remains vague and somewhat basic, and the theoretical approaches that attempt to present different perspectives for ways of understanding the innovation process, the path of knowledge is very often compartmentalized by the different scientific disciplines. In this paper, we will attempt to show the tensions and combinations that exist between the different approaches adopted by the management sciences, sociology, economics and geography in attempting to understand the innovative process. To do so, we will focus our study on the firm and the territory (as the spatial dimension of innovation, elements that have already been the subject of numerous studies to understand the forces participating in the production of novelty.Si l’innovation est devenue aujourd’hui une notion d’actualité tant elle apparaît comme fondamentale pour penser l’économie et l’adaptation de notre société à son projet de développement, reste à en définir les caractéristiques et les principes. Si le XX° siècle a été marqué par des changements importants sur un plan technologique, politique, économique ou encore culturel, l’époque actuelle semble redoubler d’efforts pour imposer l’innovation comme moteur du développement de la société.

  5. A literature review: What exactly should we preserve? How scholars address this question and where is the gap

    CERN Document Server

    Low, Jyue Tyan

    2011-01-01

    This review addresses the question of what exactly should we preserve, and how the digital preservation community and scholars address this question. The paper first introduces the much-abused-term "significant properties," before revealing how some scholars are of the opinion that characteristics of digital objects to be preserved (i.e., significant properties) can be identified and should be expressed formally, while others are not of that opinion. The digital preservation community's attempt to expound on the general characteristics of digital objects and significant properties will then be discussed. Finally, the review shows that while there may be ways to identify the technical makeup or general characteristics of a digital object, there is currently no formal and objective methodology to help stakeholders identify and decide what the significant properties of the objects are. This review thus helps open questions and generates a formative recommendation based on expert opinion that expressing an object...

    2007-07-01

    Most health professionals today have heard of 'qualitative research' but many remain confused as to what it is and how to go about doing it. In this paper, two experienced qualitative researchers become engaged in conversation exploring the question 'what is qualitative research?' Lynne Giddings and Liz Smythe are Associate Professors in the Faculty of Health & Environmental Sciences at the Auckland University of Technology. They engage a reader in exploring issues such as: What might draw you to qualitative research? How does qualitative research make a difference to practice? How can reading a qualitative research article inform practice? From a qualitative perspective, what is 'truth'? How many participants? What happens to the data? What about the bias of the researcher? Can qualitative findings be trusted? Stories and exemplars are used to highlight the processes and issues involved in undertaking a qualitative research study.

    2017-05-01

    United Nation's Sustainable Development Goals and the World Health Organization's Global Monitoring Framework support a strong global commitment to reducing the high burden of cervical and breast cancers among low- and middle-income countries. Strategies include vaccination, screening, and early diagnosis. Population-based surveys, such as those conducted by the Demographic and Health Surveys (DHS) Program, can collect the information needed to guide cancer control efforts in a standardized comparable manner. We identified and evaluated the breadth of breast and cervical cancer screening information that was collected by the DHS from 1984 through 2015. Then, we determined if these surveys currently provide the specific and measurable data about both the quantity and quality of cancer screening needed to guide national efforts to reduce the overall effects of cervical and breast cancers. We searched the DHS website to identify surveys conducted between the start of the DHS Program in 1984 and November 2015 that included questions about breast and cervical cancer screening. The relevant questions were extracted from the questionnaire, translated into English, and grouped by themes. Of the 90 countries where DHS surveys have been implemented, cervical cancer screening questions were included in 22 countries (24.4%) and breast cancer screening questions in 18 countries (20.0%). The common themes identified were disease knowledge, screening knowledge, screening practice, and screening outcomes. Most countries with survey questionnaires available for review addressed at least one aspect of screening practice (88.9% of cervical and 87.5% of breast), although few countries queried knowledge and outcomes. Questions that assess varied aspects of breast and cervical cancer screening have been incorporated into relatively few DHS surveys. The themes identified could guide the design of a standard set of questions for use in future population-based surveys and enable evaluation

  13. Survey questions about sleep duration: does asking separately about weekdays and weekends matter?

    Science.gov (United States)

    Lauderdale, Diane S

    2014-03-04

    There is no standard way to ask about sleep duration in surveys, and little is known about the comparability of different questions. This article reports on a randomized survey experiment designed to test 1 type of variation: 1 question about usual sleep hours versus 2 questions separately asking about weekday and weekend sleep. Mean sleep duration was significantly shorter (7.03 hr vs. 7.28 hr) for the single question than a weighted average from 2 questions, and race and ethnicity contrasts differed by question format. Correlations between sleep duration and reported sleep need were significantly higher for the 2-question format. These results demonstrate that question wording can affect reported sleep duration in complicated ways, making it difficult to compare studies that use different questions.

  16. The Impact of Question Format, Context, and Content on Survey Answers in Early and Late Adolescence

    Directory of Open Access Journals (Sweden)

    Diersch Nadine

    2016-06-01

    Full Text Available Self-reports in surveys are often influenced by the presented question format and question context. Much less is known about how these effects influence the answers of younger survey respondents. The present study investigated how variations in response format, answer scale frequency, and question order influence self-reports of two age groups: younger (11–13 years old and older (16–18 years old adolescents. In addition, the impact of the respondents’ level of familiarity with the question content was taken into account. Results indicated that younger adolescents are more strongly influenced by the presented question format and context than older adolescents. This, however, was dependent on the particular question content, implying that response effects are more pronounced when questions deal with issues that lie outside of the respondents’ field of experience. Implications of these findings in survey research with younger respondents are discussed.

    In this dissertation, I investigated two explanations for the variability in levels of partner violence found by large community surveys. In Study 1, I examined the effect of how questions about partner violence are introduced (question framing: conflict, violence-in-relationships, or attacks) on reports of partner violence. Although there was not a reliable effect of question framing, the pattern of findings was consistent across 3 of 4 analyses. Counter to predictions, an attacks question f...

    Mathematical models of chlamydia transmission can help inform disease control policy decisions when direct empirical evaluation of alternatives is impractical. We reviewed published chlamydia models to understand the range of approaches used for policy analyses and how the studies have responded to developments in the field. We performed a literature review by searching Medline and Google Scholar (up to October 2015) to identify publications describing dynamic chlamydia transmission models used to address public health policy questions. We extracted information on modeling methodology, interventions, and key findings. We identified 47 publications (including two model comparison studies), which reported collectively on 29 distinct mathematical models. Nine models were individual-based, and 20 were deterministic compartmental models. The earliest studies evaluated the benefits of national-level screening programs and predicted potentially large benefits from increased screening. Subsequent trials and further modeling analyses suggested the impact might have been overestimated. Partner notification has been increasingly evaluated in mathematical modeling, whereas behavioral interventions have received relatively limited attention. Our review provides an overview of chlamydia transmission models and gives a perspective on how mathematical modeling has responded to increasing empirical evidence and addressed policy questions related to prevention of chlamydia infection and sequelae.

  1. Reincarnation Revisited: Question format and the distribution of belief in reincarnation in survey research

    OpenAIRE

    2013-01-01

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

    2017-02-01

    Graduate entry nursing courses offer individuals with prior degrees the opportunity to gain nursing qualifications and facilitate career change. While it is known that accelerated graduate entry courses are increasingly popular, the perceptions of nursing held by such individuals and the influence this has on those seeking to enter the profession are less clearly understood. To explore graduate entry nursing students' perceptions of nursing on entering their pre-registration course. A descriptive design utilising cross-section survey with two open-ended questions: What do you believe the role of the nurse is? What things have influenced that view? were asked. Demographic data were analysed using descriptive frequencies, while the two open-ended questions were analysed using summative content analysis. One university-based postgraduate graduate entry nursing course in Australia PARTICIPANTS: Eight cohorts (n=286) commencing students with prior degrees other than nursing. The course attracts students from diverse backgrounds. Exposure to nursing and nurses, either as a consumer of health care or other health care role, plays a primary role in influencing career change. However, similar to those found with school leavers, there remains much misinformation about nurses' roles for students in these courses. Most identify the role of caring in nursing. For some, media representations are the only information sources. Graduate entry courses offer opportunities to attract new nurses and contribute to addressing workforce shortages. However, there is still a lack of knowledge of nursing roles among students on entry. More work is required by the profession to ensure nursing is accurately and positively represented to the community. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

  6. To bind or not to bind: addressing the question of object representation in visual short-term memory.

    2012-01-01

    Visual short-term memory (VSTM) is a capacity limited resource, which is consistently estimated to hold about four visual items at a time. There is, however, debate in the literature about what constitutes an "item" and how resources are allocated within VSTM. Some research suggests information is stored in VSTM as discrete objects; however, there is also evidence suggesting that within-object features alter VSTM performance. The present study addresses the question of whether VSTM load effects reflect the number of discrete objects and/or the number of within-object features. An electrophysiological correlate of VSTM--the contralateral delay activity (CDA)--was measured while participants performed a lateralized change-detection task, in which to-be-remembered items varied in the number of features and locations. Each trial contained either a solitary simple feature (shape, color, or orientation) or one of two multifeature arrays: three features presented at three separate locations or three features bound at one location. While presenting multiple features--regardless of whether they are at discrete locations or bound within a single object--resulted in greater CDA amplitude relative to a solitary feature, there was a dissociation in the distribution of activity between the two multifeature conditions, such that the CDA at site P1/P2 was sensitive to the number of discrete objects, while activity at P7/P8 was most enhanced when multiple features were bound in one object. The findings demonstrate the inhomogeneity of the CDA and suggest this electrophysiological marker may reflect both discrete object individuation/separation and flexible feature-feature binding in VSTM.

    2017-01-01

    Objective With the myriad of cases presented to clinicians every day at our integrated academic health system, clinical questions are bound to arise. Clinicians need to recognize these knowledge gaps and act on them. However, for many reasons, clinicians might not seek answers to these questions. Our goal was to investigate the rationale and process behind these unanswered clinical questions. Subsequently, we explored the use of biomedical information resources among specialists and primary care providers and identified ways to promote more informed clinical decision making. Methods We conducted a survey to assess how practitioners identify and respond to information gaps, their background knowledge of search tools and strategies, and their usage of and comfort level with technology. Results Most of the 292 respondents encountered clinical questions at least a few times per week. While the vast majority often or always pursued answers, time was the biggest barrier for not following through on questions. Most respondents did not have any formal training in searching databases, were unaware of many digital resources, and indicated a need for resources and services that could be provided at the point of care. Conclusions While the reasons for unanswered clinical questions varied, thoughtful review of the responses suggested that a combination of educational strategies, embedded librarian services, and technology applications could help providers pursue answers to their clinical questions, enhance patient safety, and contribute to patient-based, self-directed learning.

  11. Who Justifies Questionable Reporting Practices? Answers from a Representative Survey of Journalists in Germany

    Directory of Open Access Journals (Sweden)

    Philip Baugut

    2017-07-01

    Full Text Available Based on a secondary analysis of representative survey data of journalists in Germany (n= 1536, this paper draws attention to two variables that are important when it comes to explain whether journalists accept questionable reporting practices, such as paying people to obtain information or using confidential government documents without permission. First, perceived role achievement is important, as journalists who do not feel able to achieve an active role tend to accept questionable reporting practices more often. Second, however, this relationship is only true for journalists having a moderate tendency to the political left. Findings are explained by means of the theory of cognitive dissonance.

    Babel, Przemyslaw

    2012-12-01

    To identify factors that contribute to the high variability of the rates of use of placebo interventions reported in questionnaire surveys, the author investigated the effect of the explicit use of the word "placebo" in questionnaire surveys on placebo use in clinical practice on the results obtained. 190 primary care physicians in Poland were divided randomly into two groups. The groups received a questionnaire in which either the word placebo or the term "nonspecific methods of treatment" was used. The respondents who were asked explicitly about the use of placebo interventions declared that they never used placebo interventions significantly more often than participants asked about the use of nonspecific treatment methods. Moreover, the former reported significantly rarer use of placebo interventions than the latter. The study demonstrates that differences in the wording of questions in questionnaire surveys on placebo use can create statistically significant differences in results.

    Economic theory suggests that willingness to pay for two goods independently offered should remain unchanged when the survey instrument changes slightly. Four survey treatments consisting of comprehensive good and a subset of that good were used. The surveys alternated in the question ordering and in the embedded good which accompanied the comprehensive good. We tested for sequencing and instrument context effects using both a combined and split sample designs. In the combined sample case we found some evidence to sequencing effects in the data containing the first subset good. Likelihood ratio tests indicated that sequencing did not effect scale or location of parameters. In the test for instrument context effects, evidence was found indicating context does effect willingness to pay estimates.

    Full Text Available Household income is difficult to measure, since it requires the collection of information about all potential income sources for each member of a household.Weassess the effects of two types of edit check questions on measurement error and survey estimates: within-wave edit checks use responses to questions earlier in the same interview to query apparent inconsistencies in responses; dependent interviewing uses responses from prior interviews to query apparent inconsistencies over time.Weuse data from three waves of the British Household Panel Survey (BHPS to assess the effects of edit checks on estimates, and data from an experimental study carried out in the context of the BHPS, where survey responses were linked to individual administrative records, to assess the effects on measurement error. The findings suggest that interviewing methods without edit checks underestimate non-labour household income in the lower tail of the income distribution. The effects on estimates derived from total household income, such as poverty rates or transition rates into and out of poverty, are small.

  18. The '10 Excess' Phenomenon in Responses to Survey Questions on Happiness.

    Science.gov (United States)

    Brulé, Gaël; Veenhoven, Ruut

    2017-01-01

    Happiness in nations is typically measured in surveys using a single question. A common question is: 'all things considered, how satisfied or dissatisfied are you with your life as-a-whole these days on a scale from 0 to 10?'. The responses typically follow a uni-modal distribution with highest frequencies between 5 and 8. Yet in some nations, the percentage of 10 responses stands out and is higher than the percentage of 9 responses. This is particularly present in Latin America and in the Middle East. In this paper we explore the prevalence of the '10-excess' pattern and check some possible explanations. We conclude that the 10-excess phenomenon is partly due to cultural influence.

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

  20. A question of finding harmony: a grounded theory study of clinical psychologists' experience of addressing spiritual beliefs in therapy.

    2005-09-01

    In spite of the increasing emphasis upon spirituality in the psychological literature, research continues to highlight concerns that issues relating to spirituality are regularly overlooked within a therapeutic setting. The aim of the current study was to develop an account of the way in which clinical psychologists understand and address spirituality within therapy. Semi-structured interviews were conducted with eight clinical psychologists. The transcripts were analysed using the qualitative methodology of grounded theory, which also informed the data collection process. Two core categories were developed and termed spirituality as an elusive concept and finding harmony with spiritual beliefs. The diversity of meaning surrounding spirituality and the relative lack of engagement was found to create difficulty for constructing spirituality coherently as a concept. When specifically considering methods for identifying and addressing spiritual beliefs, contrasting approaches were identified. This diversity in understanding and approach has implications for the process and outcome of therapy, which are discussed in detail. Recommendations are suggested for developing spirituality as a more coherent and accessible concept, both within professional dialogue and the therapeutic context.

  1. DNA methylation and triplet repeat stability: New proposals addressing actual questions on the CGG repeat of fragile X syndrome

    Methylation of expanded CGG repeats in the FMR1 gene may well have different consequences. One is that methylation, extending into upstream regulatory elements, could lead to gene inactivation. Another effect of methylation, which we have obtained evidence for, could be stabilization of the repeat sequence and even prevention of premutations from expansion to full mutation. The full mutation of the fragile X syndrome probably occurs in an early transitional stage of embryonic development. The substrate is a maternally inherited premutation. The product usually is a mosaic pattern of full mutations detectable in early fetal life. These full mutation patterns are mitotically stable as, for instance, different somatic tissues of full mutation fetuses show identical mutation patterns. This raised the following questions: What triggers repeat expansion in that particular stage of development and what causes subsequent mitotic stability of expanded repeats? 21 refs., 1 fig.

  2. Using Reinterview and Reconciliation Methods to Design and Evaluate Survey Questions

    2008-06-01

    Full Text Available Conducting reinterviews is an effective method to estimate and reduce response errors in interview surveys. As part of the School Health Policies and Programs Study 2000 (SHPPS, RTI used reinterview methods to assist in designing and evaluating survey questions. Reinterviews were conducted in the field test with selected respondents to identify discrepancies between the original interviews and reinterviews. Reconciliation interviews were then conducted to determine the reasons for the discrepancies in terms of comprehension, recall, encoding, response options, or other problems. In this paper, we describe the design of the reinterview and reconciliation study and discuss the implications of using these methods for questionnaire design and evaluation, specifically in comparison to cognitive interviewing.

    2013-12-01

    Full Text Available Address-based sampling (ABS with a two-phase data collection approach has emerged as a promising alternative to random digit dial (RDD surveys for studying specific subpopulations in the United States. In 2011, the National Household Education Surveys Program Field Test used a two-phase ABS design with a postal or mail screener to identify households with eligible children and a mail topical questionnaire administered to parents of sampled children to collect measures of interest. Experiments with prepaid cash incentives and special mail delivery methods were applied in both phases. For the screener, sampled addresses were randomly designated to receive either $2 or $5 in the initial mailing. During the topical phase, incentives (ranging from $0 to $20 and delivery methods (First Class Mail or Priority Mail were assigned randomly but depended on how quickly the household had responded to the screener. The paper first evaluates the effects of incentives on response rates, and then examines incentive levels for attracting the hard-to-reach groups and improving sample composition. The impact of incentive on data collection cost is also examined.

    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.

  6. Fluid management in burn patients: results from a European survey-more questions than answers.

    Boldt, Joachim; Papsdorf, Michael

    2008-05-01

    Many strategies were proposed for fluid management in burn patients with different composition containing saline solution, colloids, or plasma. The actual clinical use of volume replacement regimen in burn patients in Europe was analysed by an international survey. A total of 187 questionnaires consisting of 20 multiple-choice questions were sent to 187 burn units listed by the European Burn Association. The response rate was 43%. The answers came from a total of 20 European countries. Volume replacement is mostly exclusively with crystalloids (always: 58%; often: 28%). The majority still use fixed formulae: 12% always use the traditional Baxter formula, in 50% modifications of this formula are used. The most often used colloid is albumin (always: 17%, often: 38%), followed by HES (always: 4%, often: 34%). Gelatins, dextrans, and hypertonic saline are used only very rarely. Fresh frozen plasma (FFP) is given in 12% of the units as the colloid of choice. Albumin was named most often to be able to improve patients' outcome (64%), followed by HES (53%), and the exclusive use of crystalloids (45%). Central venous pressure (CVP) is most often used to monitor volume therapy (35%), followed by the PiCCO-system (23%), and mixed-venous saturation (ScVO2; 10%). It is concluded that the kind of volume therapy differs widely among European burn units. This survey supported that no generally accepted volume replacement strategy in burn patients exists. New results, e.g. importance of goal-directed therapy or data concerning use of albumin in the critically ill, have not yet influenced strategies of volume replacement in the burn patient.

  7. The effect of question order on self-rated general health status in a multilingual survey context.

    Science.gov (United States)

    Lee, Sunghee; Grant, David

    2009-06-15

    Current practices recommend placing a self-rated health question before specific health items in survey questionnaires to minimize potential order effects. Because this recommendation is based on data collected in English, its applicability to other languages is unknown. This study examines whether there is an order effect associated with self-rated health for interviews conducted in English and Spanish languages. An experiment was conducted by using the 2007 California Health Interview Survey, where questions on self-rated health were inserted in 1 of 2 locations: preceding and following question items on specific chronic conditions. Respondents were randomly assigned to 1 of 2 versions of the locations by the split-half method. Although no order effect was present in the English interviews, the authors found a significant and large effect with Spanish interviews: Self-rated health appeared much worse when asked before chronic conditions than when asked after them. This order effect was larger among females than males. Order effects for self-rated health differ by interview language; inferences about the health status of Spanish-speaking populations (and potentially Latinos) depend on question order. If maintaining comparability is important, the authors' finding contradicts current recommendations, as inserting the self-rated health question before specific questions led to larger differences in health status between English and Spanish speakers.

    2007-01-01

    To carry out a study using cognitive processing interview methods to explore ways in which adolescents understand sexual orientation questions currently used on epidemiologic surveys. In-depth, individual interviews were conducted to probe cognitive processes involved in answering four self-report survey questions assessing sexual identity, sexual attraction, and sex of sexual partners.A semi-structured interview guide was used to explore variation in question interpretation, information retrieval patterns and problems, item clarity, valence of reactions to items (positive, negative, neutral), respondent burden, and perceived threat associated with the measures. Thirty adolescents aged 15 to 21 of diverse sexual orientations and race/ethnicities participated in the study, including female, male, and transgender youth. A question on sexual attraction was the most consistently understood and thus was easy for nearly all youth to answer. In contrast, a measure of sexual identity with options heterosexual, bisexual, gay/lesbian, and unsure was the most difficult to answer. Most preferred a sexual identity item that also provided the intermediate options mostly heterosexual and mostly homosexual, which many said reflected their experience of feeling between categories. Participants had varying and inconsistent interpretations of sexual behavior terms, such as sex and sexual intercourse, used in assessing the sex of sexual partners. Differences in understanding could affect interpretation of survey data in important ways. Development of valid measures of sexual orientation will be essential to better monitor health disparities.

    Methods: Results were compared from two different surveys in populations with similar characteristics. The alternatives "positive", "negative", and "don't know" (first questionnaire) were replaced with an explanatory text, "no legal sanction", four types of legal sanctions, and no possibility to answer "don't know" (second questionnaire). Four undergraduate student groups (engineering, law, medicine, and nursing) answered. Results: In the first questionnaire (n = 684) 43% accepted euthanasia (range 28–50%), 14% (8–33%) did not, and 43% (39–59%) answered "don't know". Two per cent of the respondents declined to answer. In comparison with previous surveys on attitudes to euthanasia the proportion of "don't know" was large. The results of the second questionnaire (n = 639), showed that 38% favoured "no legal prosecution" (26–50%). However, 62% (50–74%) opted for different kinds of legal sanctions, and two of four groups expressed significantly different views in the two surveys. A proportion of 10% declined to answer the second questionnaire. Conclusion: An introduction of an explanatory text and a wider range of response alternatives produced differences between the results of the two surveys conducted. PMID:15574435

  12. 'Asking the Right Question'. A Comparison of Two Approaches to Gathering Data on 'Herbals' Use in Survey Based Studies.

    Directory of Open Access Journals (Sweden)

    James S McLay

    Full Text Available Over the last decade academic interest in the prevalence and nature of herbal medicines use by pregnant women has increased significantly. Such data are usually collected by means of an administered questionnaire survey, however a key methodological limitation using this approach is the need to clearly define the scope of 'herbals' to be investigated. The majority of published studies in this area neither define 'herbals' nor provide a detailed checklist naming specific 'herbals' and CAM modalities, which limits inter-study comparison, generalisability and the potential for meta-analyses. The aim of this study was to compare the self-reported use of herbs, herbal medicines and herbal products using two different approaches implemented in succession.Cross-sectional questionnaire surveys of women attending for their mid-trimester scan or attending the postnatal unit following live birth at the Royal Aberdeen Maternity Hospital, North-East Scotland. The questionnaire utilised two approaches to collect data on 'herbals' use, a single closed yes/no answer to the question "have you used herbs, herbal medicines and herbal products in the last three months"; and a request to tick which of a list of 40 'herbals' they had used in the same time period.A total of 889 responses were obtained of which 4.3% (38 answered 'yes' to herbal use via the closed question. However, using the checklist 39% (350 of respondents reported the use of one or more specific 'herbals' (p<0.0001. The 312 respondents who reported 'no' to 'herbals' use via the closed question but "yes" via the checklist consumed a total of 20 different 'herbals' (median 1, interquartile range 1-2, range 1-6.This study demonstrates that the use of a single closed question asking about the use of 'herbals', as frequently reported in published studies, may not yield valid data resulting in a gross underestimation of actual use.

  13. New Survey Questions and Estimators for Network Clustering with Respondent-Driven Sampling Data

    Respondent-driven sampling (RDS) is a popular method for sampling hard-to-survey populations that leverages social network connections through peer recruitment. While RDS is most frequently applied to estimate the prevalence of infections and risk behaviors of interest to public health, like HIV/AIDS or condom use, it is rarely used to draw inferences about the structural properties of social networks among such populations because it does not typically collect the necessary data. Drawing on recent advances in computer science, we introduce a set of data collection instruments and RDS estimators for network clustering, an important topological property that has been linked to a network's potential for diffusion of information, disease, and health behaviors. We use simulations to explore how these estimators, originally developed for random walk samples of computer networks, perform when applied to RDS samples with characteristics encountered in realistic field settings that depart from random walks. In partic...

  14. Anthropological and demographic dimensions of the Kurdish question: Findings from census and survey data

    Full Text Available Within this study, demographic and anthropological differences between the Kurdish group and the rest of the Turkish population are presented while existing approaches on the Kurdish question based on economic and political factors are critically evaluated. Using results of the 1945 Census an inventory of all language groups in Turkey is given together with their respective ‘literacy rates’ and ‘prevalence of knowledge of Turkish’, which reveal temporal differences in terms of entrance into the demographic transition and give hints as to why some ethnic groups have adopted the Turkish identity while some other groups have remained outside the ‘Turkish core’. Recent data from the TDHS, on the other hand, is used to analyze ‘fertility’ and ‘prevalence of consanguineous marriages’ among the Kurdish population. While Kurds who use Turkish as either main or second language converge to the rest of the population in terms of both fertility decline and the matrilateral swing among consanguineous marriages, among Kurds who do not speak Turkish at all the mentioned rates increase in the opposite direction. The Turkish and Kurdish family structures are evaluated within the framework of Emmanuel Todd’s family types with special consideration on the effects of consanguineous marriages and the patrilateral inclination among these on the status of women.

    The Wide Field Infrared Survey Telescope using Astrophysics Focused Telescope Assets (WFIRST-AFTA) utilizes an existing 2.4 m diameter Hubble sized telescope donated from elsewhere in the federal government for near-infrared sky surveys and Exoplanet searches to answer crucial questions about the universe and dark energy. The WFIRST design continues to increase in maturity, detail, and complexity with each design cycle leading to a Mission Concept Review and entrance to the Mission Formulation Phase. Each cycle has required a Structural-Thermal-Optical-Performance (STOP) analysis to ensure the design can meet the stringent pointing and stability requirements. As such, the models have also grown in size and complexity leading to increased model run time. This paper addresses efforts to reduce the run time while still maintaining sufficient accuracy for STOP analyses. A technique was developed to identify slews between observing orientations that were sufficiently different to warrant recalculation of the environmental fluxes to reduce the total number of radiation calculation points. The inclusion of a cryocooler fluid loop in the model also forced smaller time-steps than desired, which greatly increases the overall run time. The analysis of this fluid model required mitigation to drive the run time down by solving portions of the model at different time scales. Lastly, investigations were made into the impact of the removal of small radiation couplings on run time and accuracy. Use of these techniques allowed the models to produce meaningful results within reasonable run times to meet project schedule deadlines.

    Survey data are often used for comparison purposes, such as comparisons across nations or comparisons over time. To be effective, this would require equivalent questions and equivalent responses options to the questions. Yet there is a lot of variation in the response scales used, which, for example, differ in the number of response options used and the labeling of these options. This is the case in happiness research, and as a result most of the research data in this field is incomparable. Several methods have been proposed to transform ratings on verbal response scales to a common numerical scale, typically ranging from 0 to 10. In this paper we give an overview of the progress made in those Scale Homogenization methods over time. We describe two early methods: Linear Stretch and the Semantic Judgement of Fixed Word Value Method. Next we discuss the Semantic Judgement of Word Value in Context Method in more detail. Based on these discussions we propose a new Reference Distribution Method. We apply the Semantic Judgement of Word Value in Context and the Reference Distribution Methods to data on happiness in The Netherlands for the years 1989-2009. We show that the Reference Distribution Method produces comparable time series on different questions and that it allows discontinuities in data to be corrected.

    There is no consensus among patients and healthcare professionals (HCPs) on the topics that need to be addressed after oesophageal cancer surgery. The aim of this study was to identify these topics, using a two-round Delphi survey. In round 1, patients and HCPs (surgeons, dieticians, nurses) were invited to rate the importance of 49 topics. The proportion of panellists that considered a topic to be of low, moderate or high importance was then calculated for each of these two groups. Based on these proportions and the i.q.r., topics were categorized as: 'consensus to be included', 'consensus to be excluded' and 'no consensus'. Only topics in the first category were included in the second round. In round 2, panellists were provided with individual and group feedback. To be included in the final list, topics had to meet criteria for consensus and stability. There were 108 patients and 77 HCPs in the round 2 analyses. In general, patients and HCPs considered the same topics important. The final list included 23 topics and revealed that it was most important to address: cancer removed/lymph nodes, the new oesophagus, eating and drinking, surgery, alarming new complaints and the recovery period. The study provides surgeons with a list of topics selected by patients and HCPs that may be addressed systematically at the initial follow-up consultation after oesophageal cancer surgery. © 2014 BJS Society Ltd.

    A central theme in cross-cultural psychology is the extent to which cognitive mechanisms are universal, or, alternatively, are specific to a given culture. We propose a new way to tackle this question: to use the same cognitive architecture, implemented as a computer program, for simulating phenomena in which individuals from different cultures perform a task familiar to their own culture. The CHREST architecture (Gobet et al., 2001; Gobet & Simon, 2000) has simulated a number of empirical ph...

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

    Despite the likelihood of poor quality data flowing from clinical information systems to public health information systems, current policies and practices are pushing for the adoption and use of even greater numbers of electronic data feeds. However, using poor data can lead to poor decision-making outcomes in public health. Therefore public health informatics professionals need to assess, and periodically re-evaluate, the quality of electronic data and their sources. Unfortunately there is currently a paucity of tools and strategies in use across public health agencies. Our Center of Excellence in Public Health Informatics is working to develop and disseminate tools and strategies for supporting on-going assessment of data quality and solutions for overcoming data quality challenges. In this article, we outline the need for better data quality assessment and our approach to the development of new tools and strategies. In other words, public health informatics professionals need to ask questions about the electronic data received by public health agencies, and we hope to create tools and strategies to help informaticians ask questions that will lead to improved population health outcomes.

    This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability. The KPNO Mayall 4m telescope equipped with the DOE- and internationally-funded BigBOSS spectrograph offers one of the most cost-efficient ways of accomplishing many of the pressing scientific goals identified for this decade by the "New Worlds, New Horizons" report. The BigBOSS Key Project will place unprecedented constraints on cosmological parameters related to the expansion history of the universe. With the addition of an open (publicly funded) community access component, the scientific impact of BigBOSS can be extended to many important astrophysical questions related to the origin and evolution of galaxies, stars, and the IGM. Massive spectroscopy is the critical missing ingredient in numerous ongoing and planned ground- and space-based surveys, and BigBOSS is unique in its ability to provide this to the US community.

    Survey research on subjective wellbeing in The Netherlands started in the early 1970s. The time series happiness and life satisfaction that have emerged since then are unfortunately based on slightly different survey items of which one part uses verbal response scales and another part uses numerical response scales. The diversity of the survey items and a number of other measurement issues, such as the effects of changes in survey mode, hamper comparison over time and make it difficult to establish whether life became any better over the last forty years. These problems can be tackled using the recently developed Reference Distribution Method with which responses to equivalent but not identical survey questions can be pooled to obtain long, consistent time series. We applied the Reference Distribution method to pool time series of happiness and life satisfaction. We conclude that in the past 40 years the Dutch have become slightly happier and satisfied with their lives.

    Full Text Available Insect consumption (entomophagy is a potentially high nutritious and healthy source of food with high fat, protein, vitamin, fiber and micronutrient content. At least 2 billion people globally eat insects (over 1900 edible species though this habit is regarded negatively by others. There is a limited amount of data on the perception and consumption of insects. We conducted a national cross-sectional survey in the Lao People's Democratic Republic (Laos to assess the prevalence and characteristics of insect consumption among adult lay people and insect vendors.We conducted a multi stage randomized national survey in 1303 households in 96 villages in 16 Lao provinces. Three insect vendors or collectors per village were also included. A standardized pretested questionnaire addressed the following issues: socioeconomic characteristics, type of insects consumed and frequency of consumption, reasons and trends in consumption as well as reports on side effects, over the last 10 years.A total of 1059 adults (Sex ratio F/M: 1.2, 30 ethnic groups, and 256 vendors were enrolled. A total of 1025 (96.8% lay people were currently insect consumers, 135 (13.0% daily or weekly consumers, and 322 (31.1% consumed several times per month. For the majority (575, 55.6% the consumption was infrequent (less than a few times per year and only 22 (2% had never eaten insects. Consumption started in childhood. Insect availability was seasonal (670, 63.2% and respondents would have eaten more insects, if they had been more available (919, 86.7%. Hmong and Leu ethnic groups had significantly lower consumption levels than the general population. Eggs of weaver ants, short-tailed crickets, crickets, grasshoppers, and cicadas were the top 5 insects consumed. Consumption had decreased in the last decade, mostly due to less availability (869; 84.0% and change of life (29; 5.5%.

    During the past decade, the internet has become a major information resource in various domains of life and a communication venue among young people and adolescents who seek health information via the internet. Until now, the contents of Israeli adolescents' questions regarding health issues on internet sites have not been published. (1) A survey of the characteristics of adolescents who seek health information and their questions presented to the Ynet forum "The body during adolescence". In this forum physicians experienced in adolescent medicine respond to these questions and to comments of other forum participants. (2) Presentation of problematic issues in professionals' responses to health questions in the internet. Survey of a representative sample of contacts to the Ynet forum "The body during adolescence" during 2009 gathering information on gender and age of contacting person, parents' contacts, contacts' contents and physicians responses. A total of 412 contacts were surveyed, 210 (51%) females, aged 14-17 years--60%, 10-13 years--17% and 18-21 years 15%. Parents' questions appeared in 39 (9%) of contacts. Of all contacts, 44% related to sexuality issues and 17% related to self image and body composition. The physicians provided complete responses to 60% of the contacts, while in 40% the physician's responses included referral to clinical medical consultation. An internet health forum enables adolescents and parents to ask questions and raise doubts and anxieties regarding various health issues without the fear of being exposed and enables them to express their concerns face-to-face with a healthcare provider Sensitive issues regarding sexuality and self-image, which are not raised frequently during clinical encounters, are expressed and receive professional responses in the forum. Notwithstanding the significance of a rapid professional contribution, physicians responding to contacts in internet forums need to recognize the barrier related to professional

    Full Text Available Head of Line blocking phenomenon is common in First in First Out (FIFO nature queues. Head of line blocking problem becomes significant in wireless ad hoc networks using directional antennas as it uses FIFO queue which consists of packets intended for different directions. A packet on the top of the queue may block the remaining packets if it finds the medium busy in its intended direction, where as the packets in the queue intended for other directions may find the medium to be idle. Very few of the MAC protocols for ad hoc networks using directional antennas have addressed this problem. In this paper we will exploit the Head of Line Blocking problem and review the protocols that have addressed the head of Line Blocking Problem.

    Full Text Available CONTEXTO: A família é a arena primária na qual a criança desenvolve a sua sociabilização. As experiências tidas neste sistema podem constituir um factor protector ou de risco, contribuindo para a sua vulnerabilidade ou resiliência diante de desordens mentais quando adulto. A avaliação da história familiar de experiências emocionais relevantes é problemática, e o uso de instrumentos psicométricos pode auxiliar a superar certas limitações metodológicas. OBJECTIVOS: Desenvolver três subquestionários para avaliação das experiências emocionais decorridas no contexto familiar da infância até a adolescência. Esses instrumentos são adaptações para o português do Family Background Questionnaire (FBQ tratando dos cuidados paliativos e do ambiente familiar e são administrados retrospectivamente a adultos. MÉTODOS: Três versões do FBQ que tratam de (1 cuidados paternos, (2 cuidados maternos e (3 ambiente familiar foram produzidas. Os questionários foram aplicados a 280 participantes. A avaliação das propriedades psicométricas desses questionários teve como base a determinação da consistência interna, análise factorial e correlação de Spearman. RESULTADOS: Os três questionários mostraram-se adequados para avaliação de seus respectivos domínios. CONCLUSÕES: A avaliação objetiva das primeiras experiências emocionais no contexto familiar produz insights importantes para a compreensão do desenvolvimento psicológico, com implicações clínicas e de investigação.BACKGROUND: Family is the primary setting where children develop their social skills.

    Monitoring to detect temporal trends in biological and habitat indices is a critical component of fisheries management. Thus, it is important that management objectives are linked to monitoring objectives. This linkage requires a definition of what constitutes a management-relevant “temporal trend.” It is also important to develop expectations for the amount of time required to detect a trend (i.e., statistical power) and for choosing an appropriate statistical model for analysis. We provide an overview of temporal trends commonly encountered in fisheries management, review published studies that evaluated statistical power of long-term trend detection, and illustrate dynamic linear models in a Bayesian context, as an additional analytical approach focused on shorter term change. We show that monitoring programs generally have low statistical power for detecting linear temporal trends and argue that often management should be focused on different definitions of trends, some of which can be better addressed by alternative analytical approaches.

    From jets to cosmos to cosmic censorship P S Joshi Tata Institute of Fundamental Research, Homi Bhabha Road, Colaba, Mumbai 400005, India E-mail: psj@tifr.res.in 1. Introduction At the outset, I should like to acknowledge that part of the title above, which tries to capture the main flavour of this meeting, and has been borrowed from one of the plenary talks at the conference. When we set out to make the programme for the conference, we thought of beginning with observations on the Universe, but then we certainly wanted to go further and address deeper questions, which were at the very foundations of our inquiry, and understanding on the nature and structure of the Universe. I believe, we succeeded to a good extent, and it is all here for you in the form of these Conference Proceedings, which have been aptly titled as 'Vishwa Mimansa', which could be possibly translated as 'Analysis of the Universe'! It is my great pleasure and privilege to welcome you all to the ICGC-2011 meeting at Goa. The International Conference on Gravitation and Cosmology (ICGC) series of meetings are being organized by the Indian Association for General Relativity and Gravitation (IAGRG), and the first such meeting was planned and conducted in Goa in 1987, with subsequent meetings taking place at a duration of about four years at various locations in India. So, it was thought appropriate to return to Goa to celebrate the 25 years of the ICGC meetings. The recollections from that first meeting have been recorded elsewhere here in these Proceedings. The research and teaching on gravitation and cosmology was initiated quite early in India, by V V Narlikar at the Banares Hindu University, and by N R Sen in Kolkata in the 1930s. In course of time, this activity grew and gained momentum, and in early 1969, at the felicitation held for the 60 years of V V Narlikar at a conference in Ahmedabad, P C Vaidya proposed the formation of the IAGRG society, with V V Narlikar being the first President.

This study shows how it is possible to develop healthful eating indicators based on dietary guidelines from a cross sectional population survey. Adults 18 to 64 years answered questions about the type and amount of foods eaten the previous day, including fruit, vegetables, cereals, dairy, fish or meat and fluids. Scores were based on serves and types of food according to an established method. Factor analysis indicated two factors, confirmed by structural equation modeling: a recommended food healthful eating indicator (RF_HEI and a discretionary food healthful eating indicator (DF_HEI. Both yield mean scores similar to an established dietary index validated against nutrient intake. Significant associations for the RF_HEI were education, income, ability to save, and attitude toward diet; and for the DF_HEI, gender, not living alone, living in a socially disadvantaged area, and attitude toward diet. The results confirm that short dietary questions can be used to develop healthful eating indicators against dietary recommendations. This will enable the exploration of dietary behaviours for “at risk” groups, such as those with excess weight, leading to more relevant interventions for populations.

    Hannes Schröter

    Full Text Available This study assessed the prevalence of physical and cognitive doping in recreational triathletes with two different randomized response models, that is, the Cheater Detection Model (CDM and the Unrelated Question Model (UQM. Since both models have been employed in assessing doping, the major objective of this study was to investigate whether the estimates of these two models converge.An anonymous questionnaire was distributed to 2,967 athletes at two triathlon events (Frankfurt and Wiesbaden, Germany. Doping behavior was assessed either with the CDM (Frankfurt sample, one Wiesbaden subsample or the UQM (one Wiesbaden subsample. A generalized likelihood-ratio test was employed to check whether the prevalence estimates differed significantly between models. In addition, we compared the prevalence rates of the present survey with those of a previous study on a comparable sample.After exclusion of incomplete questionnaires and outliers, the data of 2,017 athletes entered the final data analysis. Twelve-month prevalence for physical doping ranged from 4% (Wiesbaden, CDM and UQM to 12% (Frankfurt CDM, and for cognitive doping from 1% (Wiesbaden, CDM to 9% (Frankfurt CDM. The generalized likelihood-ratio test indicated no differences in prevalence rates between the two methods. Furthermore, there were no significant differences in prevalences between the present (undertaken in 2014 and the previous survey (undertaken in 2011, although the estimates tended to be smaller in the present survey.The results suggest that the two models can provide converging prevalence estimates. The high rate of cheaters estimated by the CDM, however, suggests that the present results must be seen as a lower bound and that the true prevalence of doping might be considerably higher.

    Cabrera Services Inc. (CABRERA) is the remedial contractor for the Shallow Land Disposal Area (SLDA) Site in Armstrong County Pennsylvania, a United States (US) Army Corps of Engineers - Buffalo District (USACE) contract. The remediation is being completed under the USACE's Formerly Utilized Sites Remedial Action Program (FUSRAP) which was established to identify, investigate, and clean up or control sites previously used by the Atomic Energy Commission (AEC) and its predecessor, the Manhattan Engineer District (MED). As part of the management of the FUSRAP, the USACE is overseeing investigation and remediation of radiological contamination at the SLDA Site in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 US Code (USC), Section 9601 et. seq, as amended and, the National Oil and Hazardous Substance Pollution Contingency Plan (NCP), Title 40 of the Code of Federal Regulations (CFR) Section 300.430(f) (2). The objective of this project is to clean up radioactive waste at SLDA. The radioactive waste contains special nuclear material (SNM), primarily U-235, in 10 burial trenches, Cabrera duties include processing, packaging and transporting the waste to an offsite disposal facility in accordance with the selected remedial alternative as defined in the Final Record of Decision (USACE, 2007). Of particular importance during the remediation is the need to address nuclear criticality safety (NCS) controls for the safe exhumation and management of waste containing fissile materials. The partnership between Cabrera Services, Inc. and Measutronics Corporation led to the development of a valuable survey tool and operating procedure that are essential components of the SLDA Criticality Safety and Material Control and Accountability programs. Using proven existing technologies in the design and manufacture of the Mobile Survey Cart, the continued deployment of the Cart will allow for an efficient and reliable

  5. Addressivity in cogenerative dialogues

    2014-03-01

    Ashraf Shady's paper provides a first-hand reflection on how a foreign teacher used cogens as culturally adaptive pedagogy to address cultural misalignments with students. In this paper, Shady drew on several cogen sessions to showcase his journey of using different forms of cogens with his students. To improve the quality of cogens, one strategy he used was to adjust the number of participants in cogens. As a result, some cogens worked and others did not. During the course of reading his paper, I was impressed by his creative and flexible use of cogens and at the same time was intrigued by the question of why some cogens work and not others. In searching for an answer, I found that Mikhail Bakhtin's dialogism, especially the concept of addressivity, provides a comprehensive framework to address this question. In this commentary, I reanalyze the cogen episodes described in Shady's paper in the light of dialogism. My analysis suggests that addressivity plays an important role in mediating the success of cogens. Cogens with high addressivity function as internally persuasive discourse that allows diverse consciousnesses to coexist and so likely affords productive dialogues. The implications of addressivity in teaching and learning are further discussed.

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

    Transfer of knowledge across the science-society interface is essential for both, ethical and economic reasons, and inevitable for successful climate change adaptation and integrated management of sustainable, resilient landscapes. The transdisciplinary research of connectivity (which is the degree to which a system facilitates the movement of matter and energy through itself. It is an emergent property of the system state, Connecteur web resources,2015) has the potential to supply monitoring, modelling and management tools to land and water managers in order to reach these goals. The research of water and sediment connectivity has received significant and increasing scientific attention across the entire realm of the environmental disciplines, and the COST Action ES 1306 Connecteur facilitates the multi-sectorial collaboration in connectivity research at EU level. In order to appropriately address the transfer of the cutting edge research developments of the Connecteur network, the collaborative research project on stakeholders' perception of connectivity was conducted by the Working Group 5 "Transition of connectivity research towards sustainable land and water management". The questionnaire survey on stakeholder perception was conducted by volunteering scientist involved in the Connecteur network together from 19 European countries. Together 84 stakeholders from all mayor sectors in water and land management were asked about the main challenges of their work, their understanding of connectivity, the desired areas of cooperation with connectivity science, and the best tools for transferring knowledge. The results showed differences between different stakeholders groups in the way they percept and work with connectivity, as well as their requirement of knowledge transfers. While farmers, and (in lower extend) the agricultural administration officers articulated no, or little need for connectivity management, the majority of stakeholders involved in land and water

    The Secretary of India's Ministry of Health and Family Welfare serves as Chair of the Executive Council of the International Institute for Population Sciences in Bombay. She addressed its 35th convocation in 1993. Global population stands at 5.43 billion and increases by about 90 million people each year. 84 million of these new people are born in developing countries. India contributes 17 million new people annually. The annual population growth rate in India is about 2%. Its population size will probably surpass 1 billion by the 2000. High population growth rates are a leading obstacle to socioeconomic development in developing countries. Governments of many developing countries recognize this problem and have expanded their family planning programs to stabilize population growth. Asian countries that have done so and have completed the fertility transition include China, Japan, Singapore, South Korea, and Thailand. Burma, Malaysia, North Korea, Sri Lanka, and Vietnam have not yet completed the transition. Afghanistan, Bangladesh, Iran, Nepal, and Pakistan are half-way through the transition. High population growth rates put pressure on land by fragmenting finite land resources, increasing the number of landless laborers and unemployment, and by causing considerable rural-urban migration. All these factors bring about social stress and burden civic services. India has reduced its total fertility rate from 5.2 to 3.9 between 1971 and 1991. Some Indian states have already achieved replacement fertility. Considerable disparity in socioeconomic development exists among states and districts. For example, the states of Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh have female literacy rates lower than 27%, while that for Kerala is 87%. Overall, infant mortality has fallen from 110 to 80 between 1981 and 1990. In Uttar Pradesh, it has fallen from 150 to 98, while it is at 17 in Kerala. India needs innovative approaches to increase contraceptive prevalence rates

    Ladies and Gentlemen, It is an honor for me to present my welcome address in the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3), as the president of Kanto Gakuin University. Particularly to those from abroad more than 17 countries, I am very grateful for your participation after long long trips from your home to Yokohama. On the behalf of the Kanto Gakuin University, we certainly welcome your visit to our university and stay in Yokohama. First I would like to introduce Kanto Gakuin University briefly. Kanto Gakuin University, which is called KGU, traces its roots back to the Yokohama Baptist Seminary founded in 1884 in Yamate, Yokohama. The seminary's founder was Albert Arnold Bennett, alumnus of Brown University, who came to Japan from the United States to establish a theological seminary for cultivating and training Japanese missionaries. Now KGU is a major member of the Kanto Gakuin School Corporation, which is composed of two kindergartens, two primary schools, two junior high schools, two senior high schools as well as KGU. In this university, we have eight faculties with graduate school including Humanities, Economics, Law, Sciences and Engineering, Architecture and Environmental Design, Human and Environmental Studies, Nursing, and Law School. Over eleven thousands students are currently learning in our university. By the way, my major is the geotechnical engineering, and I belong to the faculty of Sciences and Engineering in my university. Prof. T. Yamada, here, is my colleague in the same faculty. I know that the nuclear physics is one of the most active academic fields in the world. In fact, about half of the participants, namely, more than 50 scientists, come from abroad in this conference. Moreover, I know that the nuclear physics is related to not only the other fundamental physics such as the elementary particle physics and astrophysics but also chemistry, medical sciences, medical cares, and radiation metrology

    Ladies and Gentlemen To quote Mr Jean Terrien: "Physics must be one step ahead of metrology". A long-serving Director of the BIPM, he said these words when visiting the IMGC in 1970 as a member of the scientific board of our Institute. At that time it was still an open question whether the IMGC should start research work on the absolute measurement of silicon lattice spacing. Mr Terrien underlined the revolutionary character of x-ray interferometry and, eventually, he caused the balance needle to lean towards the ... right direction. Mr Terrien correctly foresaw that, like Michelson's interferometer of 1880, x-ray interferometry could have a prominent place in today's science and technology. And while, in the first case, after more than a century we can see instruments based on electromagnetic wave interaction within every one's reach in laboratories and, sometimes, in workshops, in the second case, twenty-five years since the first development of an x-ray interferometer we can witness its role in nanometrology. Today and tomorrow we meet to discuss how to go beyond the sixth decimal place in the value of the Avogadro constant. We are aware that the quest for this achievement requires the cooperation of scientists with complementary capabilities. I am sure that the present workshop is a very good opportunity to present and discuss results and to improve and extend existing cooperation. The new adjustment of fundamental constants envisaged by the CODATA Task Group is redoubling scientists' efforts to produce competitive values of NA. The results of the measurements of the silicon lattice spacing in terms of an optical wavelength, which were available for the 1986 adjustment, combined with the determination of silicon molar volume, demonstrate how such an NA determination produces a consistent set of other constants and opens the way to a possible redefinition of the kilogram. We shall see in these two days how far we have progressed along this road. For us at the

  18. Questions about elastic waves

    CERN Document Server

    Engelbrecht, Jüri

    2015-01-01

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

    Mobile laboratory data offers unprecedented ground-level temporal and spatial resolution of several kinds of emission plumes. With clusters of dedicated chemical composition instruments at high time resolution and specificity, various compound ratios can be used to distinguish plume origins. When detailed wind measurements are also acquired, it is tempting to couple the composition data into inversion models to deduce source emission strengths. Here, data from the Aerodyne Mobile Laboratory, operating in Houston Ship Channel during early 2015 is examined. Emission sources are identified and quantified using atmospheric dispersion simulations using Gaussian models and an advanced SCIPUFF (Second-order Closure Integrated Puff) model. Error in these inversions is estimated using controlled releases of inert tracers over similar terrain and weather conditions. Though the inversion methods will have uncertainty in the estimate of the emission strength, the sources are typically unambiguously identified.

    Estimation of fish stock size distributions from survey data requires knowledge about gear selectivity. However, selectivity models rest on assumptions that seldom are analyzed. Departures from these can lead to misinterpretations and biased management recommendations. Here, we use survey data...... on great Arctic char (Salvelinus umbla) to analyze how correcting for entanglement of fish and nonisometric growth might improve estimates of selectivity curves, and subsequently estimates of size distribution and age-specific mortality. Initial selectivity curves, using the entire data set, were wide...... and asymmetric, with poor model fits. Removing potentially nonmeshed fish had the greatest positive effect on model fit, resulting in much narrower and less asymmetric selection curves, while attempting to take nonisometric growth into account, by using girth rather than length, improved model fit...

    The first section of this memoir queries my formative years. Indirectly I address the question, did my childhood and early years make a difference in my choice of career? Why and how did I begin my journey to becoming a scientist? Did I choose the field of solar astronomy or did circumstances dictate it for me? In the second section, I travel through my work environments and experiences, talking about interactions and aspects of being a scientist that do not appear in our research papers. What parts of my research were happenstances and what parts did I plan? What does it feel like to be on scientific quests? Using examples in my journey, I also turn to questions that have intrigued me throughout my sojourn as a solar astronomer. How do scientific discoveries come about? What factors lead to little discoveries? And what factors lead to major exciting discoveries? Are there timely questions we do not think to ask? How can small, seemingly scattered pieces of knowledge suddenly coalesce into a deeper understanding - what is called the "Aha!" experience - the times when our mental light switches on, and with child-like wonder we behold a "big picture"?

    Since 2004 NASA has surveyed users of its Earth Observing System Data and Information System (EOSDIS) to determine user satisfaction with its services. The surveys have been conducted by CFI Group under contract with the Federal Consulting Group, Executive Agent in government for the American Customer Satisfaction Index (ACSI). The purpose of these annual surveys is to help EOSDIS and the data centers assess current status and improve future services. The survey questions include demographic and experiential questions in addition to the ACSI and EOSDIS specific rating questions. In addition to customer satisfaction, analysis of each year's results has provided insight into the survey process. Although specific questions have been added, modified, or deleted to reflect changes to the EOSDIS system and processes, the model rating questions have remained the same to ensure consistency for evaluating cross year trends. Working with the CFI Group, we have refined the invitation and questions to increase clarity and address the different ways diverse groups of users access services at EOSDIS data centers. We present challenges in preparing a single set of questions that go to users with backgrounds in many Earth science disciplines. These users may have contacted any of the 12 EOSDIS data centers for information or may have accessed data or data products from many kinds of aircraft and satellite instruments. We discuss lessons learned in preparing the invitation and survey questions and the steps taken to make the survey easier to complete and to encourage increased participation.

  4. The Value Question in Metaphysics.

    Science.gov (United States)

    Kahane, Guy

    2012-07-01

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

    We present a novel methodology for modeling emission line galaxy samples that span the entire BPT diagram. Our methodology has several advantages over current modeling schemes: the free variables in the model are identical for both AGN and SF galaxies; these free variables are more closely linked to observable galaxy properties; and the ionizing spectra including an AGN and starlight are handled self-consistently rather than empirically. We show that our methodology is capable of fitting the vast majority of SDSS galaxies that fall within the traditional regions of galaxy classification on the BPT diagram. We also present current results for relaxing classification boundaries and extending our galaxies into the dwarf regime, using the REsolved Spectroscopy of a Local VolumE (RESOLVE) survey and the Environmental COntext (ECO) catalog, with special attention to compact blue E/S0s. We compare this methodology to PCA decomposition of the spectra. This work is supported by National Science Foundation awards AST-0955368 and CISE/ACI-1156614.

    This study, supported by the Rwandan Ministry of Health and the World Health Organization, was conducted in 2005 to determine the prevalence of epilepsy and its sociocultural perception in Rwanda, as well as epilepsy-related knowledge and practices of health-care professionals (HCPs). A cross-sectional, nationally representative survey was conducted throughout Rwanda by trained investigators. Participants were recruited by random cluster sampling based on the organization of administrative units in the country. Overall, 1137 individuals (62% from rural areas) were interviewed. The prevalence of epilepsy was estimated to be 49 per 1000 people or 41 per 1000 for active epilepsy. Onset of epilepsy before the age of 2years was reported in 32% of the cases. Family history of epilepsy, head trauma, and premature delivery were reported in 53%, 50%, and 68% of the cases, respectively. Most (68%) patients did not receive any medical treatment for epilepsy; 21.5% had received some form of traditional treatment. According to responses from the general population, people with epilepsy should not be entitled to schooling (according to 66%), to work (according to 72%), to the use of public places (according to 69%), or to marriage (according to 66%). Furthermore, 50% believed that epilepsy was untreatable, and 40% thought that it was transmissible. Of the 29 HCPs interviewed, the majority knew the definition of epilepsy and status epilepticus, as well as basic treatment options and side effects. However, 90% believed that treatment was only necessary in the first week after a seizure. Living with epilepsy was associated heavily with stigma, and a significant treatment gap (68%) was identified. Following this study, numerous actions have been taken by the Rwandan government, the Rwandan League Against Epilepsy, and several nongovernmental organizations to increase awareness about epilepsy and to close the treatment gap. An overview of these activities is provided.

  9. Trick questions: cosmopolitan hospitality

    Directory of Open Access Journals (Sweden)

    Eleanor Byrne

    2013-08-01

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

    Lesbian, gay, bisexual, transgender and queer/questioning (LGBTQ) people frequently report negative health care encounters. Medical professionals may inadequately manage LGBTQ persons' health if they have not received training in this area. An anonymous survey measuring efficacy in health situations among LGBTQ persons was answered by 166 medical students across all years of a UK university. Results show that 84.9% of participants reported a lack of LGBTQ health care education, with deficits in confidence clarifying unfamiliar sexual and gender terms, deciding the ward in which to nurse transgender patients, finding support resources, and discussing domestic abuse with LGBTQ patients. Most participants reported that they would not clarify gender pronouns or ask about gender or sexual identity in mental health or reproductive health settings. Participants reported infrequently observing doctors making similar inquiries. Participants held positive attitudes toward LGBTQ patients, with attitude scores positively correlating with LGBTQ terminology knowledge scores (rs = 0.5052, p LGBTQ patients.

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

    Information seeking is one of human needs today. Comparing things using search engine surely take more times than search only one thing. In this paper, we analyzed comparative questions for comparative question answering system. Comparative question is a question that comparing two or more entities. We grouped comparative questions into 5 types: selection between mentioned entities, selection between unmentioned entities, selection between any entity, comparison, and yes or no question. Then we extracted 4 types of information from comparative questions: entity, aspect, comparison, and constraint. We built classifiers for classification task and information extraction task. Features used for classification task are bag of words, whether for information extraction, we used lexical, 2 previous and following words lexical, and previous label as features. We tried 2 scenarios: classification first and extraction first. For classification first, we used classification result as a feature for extraction. Otherwise, for extraction first, we used extraction result as features for classification. We found that the result would be better if we do extraction first before classification. For the extraction task, classification using SMO gave the best result (88.78%), while for classification, it is better to use naïve bayes (82.35%).

    2017-01-04

    Contraceptive advice and supply (CAS) and sexually transmitted infection (STI) testing are increasingly provided in primary care. Most risk assessment tools are based on sexual risk behaviours and socio-demographics, for use online or in specialist services. Combining socio-demographic and psychosocial questions (e.g. religious belief and formative experience) may generate an acceptable tool for targeting women in primary care who would benefit from intervention. We aimed to identify psychosocial and socio-demographic factors associated with reporting key sexual risk behaviours among women in the British general population. We undertook complex survey analysis of data from 4911 hetero-sexually active women aged 16-44 years, who participated in Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a national probability sample survey undertaken 2010-2012. We used multivariable regression to examine associations between the available psychosocial and socio-demographic variables in Natsal-3 and reports of three key sexual behaviours: a) 2+ partners in the last year (2PP); b) non-use of condoms with 2+ partners in the last year (2PPNC); c) non-use of condoms at first sex with most recent sexual partner (FSNC). We adjusted for key socio-demographic factors: age, ethnicity and socio-economic status (measured by housing tenure). Weekly binge drinking (6+ units on one occasion), and first sex before age 16 were each positively associated with all three sexual behaviours after adjustment. Current relationship status, reporting drug use (ever), younger age and living in rented accommodation were also associated with 2+ partners and 2 + partners without condoms after adjustment. Currently being a smoker, older age and respondent ethnicity were associated with FSNC after adjustment for all other variables. Current smoking status, treatment for depression (last year), and living at home with both parents until the age of 14 were each associated with

    The MINDMAP consortium (2016-2019) aims to identify opportunities provided by the urban environment for the promotion of mental well-being and functioning of older people in Europe by bringing together European cities with urban longitudinal ageing studies: GLOBE, HAPIEE, HUNT, LASA, LUCAS, RECORD, Rotterdam Study, Turin Study. A survey on mental healthcare planning policies and programmes dedicated to older persons covering the range from health promotion to need of nursing care was performed for profound data interpretation in Amsterdam, Eindhoven, Hamburg, Helsinki, Kaunas, Krakow, London, Nord-Trøndelag, Paris, Prague, Rotterdam and Turin. To collect detailed information on healthcare planning policies and programmes across these European cities to evaluate variations and to delineate recommendations for sciences, policies and planners using experience from evidence-based practice feedback from the MINDMAP cities. The MINDMAP partners identified experts in the 12 cities with the best background knowledge of the mental health sector. After pretesting, semi-structured telephone interviews (1-2 h) were performed always by the same person. A structured evaluation matrix based on the geriatric functioning continuum and the World Health Organization (WHO) Public Health Framework for Healthy Ageing was applied. A complete survey (12 out of 12) was performed reporting on 41 policies and 280 programmes on the city level. It appeared from extensive analyses that the focus on older citizens, specific target groups, and multidimensional programmes could be intensified. There is a broad variety to cope with the challenges of ageing in health, and to address both physical and mental capacities in older individuals and their dynamic interactions in urban environments.

    Full Text Available Abstract Background The value of the Internet to deliver preoperative education would increase if there was variability in questions patients want answered. This study's goal was to have patients consulting an orthopedic surgeon about undergoing either a total hip arthroplasty (THA or a total knee arthroplasty (TKA rate the importance of different questions concerning their care. Methods We assembled questions patients might have about joint replacement surgery by analyzing the literature and querying a pilot group of patients and surgeons. Twenty-nine patients considering undergoing THA and 19 patients considering TKR completed a written survey asking them to rate 30 different questions, with a 5 point Likert scale from 1 (least important – 5 (most important. Results For patients considering THA or TKR, the 4 highest rated questions were: Will the surgery affect my abilities to care for myself?, Am I going to need physical therapy?, How mobile will I be after my surgery?, When will I be able to walk normally again? The mean percentage disagreement was 42% for questions answered by TKR patients and 47% for the THA group. Some patients gave a high rating to questions lowly rated by the rest of the group. Conclusions Although there was enough agreement to define a core set of questions that should be addressed with most patients considering THA or TKA, some of the remaining questions were also highly important to some patients. The Web may offer a flexible medium for accommodating this large variety of information needs.

  17. Barriers to optimal care between physicians and lesbian, gay, bisexual, transgender, and questioning adolescent patients.

    Science.gov (United States)

    Kitts, Robert Li

    2010-01-01

    The objective of this article was to identify barriers to optimal care between physicians and LGBTQ (lesbian, gay, bisexual, transgender, and questioning) adolescents. To this end, 464 anonymous, self-administered surveys were distributed in 2003 to residents and attending physicians in pediatrics, internal medicine, obstetrics-gynecology, psychiatry, emergency medicine, and family practice at Upstate Medical University. The survey included questions pertaining to practice, knowledge, and attitude pertaining to lesbian, gay, transgender, or questioning (LGBTQ) adolescents. One hundred eight four surveys were returned. The majority of physicians would not regularly discuss sexual orientation, sexual attraction, or gender identity while taking a sexual history from a sexually active adolescent. As well, the majority of physicians would not ask patients about sexual orientation if an adolescent presented with depression, suicidal thoughts, or had attempted suicide. If an adolescent stated that he or she was not sexually active, 41% of physicians reported that they would not ask additional sexual health-related questions. Only 57% agreed to an association between being a LGBTQ adolescent and suicide. The majority of physicians did not believe that they had all the skills they needed to address issues of sexual orientation with adolescents, and that sexual orientation should be addressed more often with these patients and in the course of training. This study concludes that barriers in providing optimal care for LGBTQ adolescents can be found with regard to practice, knowledge, and attitude regardless of medical field and other demographics collected. Opportunities exist to enhance care for LGBTQ adolescents.

    This paper addresses problems common in the listening classes, namely, lack of motivation, orientation and sense of achievement and the presence of pressure, fear and frustration. The author examines different factors in the teaching of listening and poses 6 questions that might help teachers to reflect on their teaching. The conclusion is that the aim of listening class is to develop rather than test listening strategies and skills; that students need to be provided with communicative tasks before and while listening; that materials should be realistic, varied and graded ; that listening should be integrated with other skills development; and finally, that learner autonomy provides the ultimate solution to listening problems.

Application of the logic of inference to this set of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous quantity that describes the bearing or relevance that a question has on an outstanding issue. These have been extended to suggest that the logic of inquiry results in functional relationships analogous to, although more general than, those found in information theory. Employing lattice theory, I examine in greater detail the structure of the space of assertions and questions demonstrating that the symmetries between the logical relations in each of the spaces derive directly from the lattice structure. Furthermore, I show that while symmetries between the spaces exist, the two lattices are not isomorphic. The lattice of assertions is described by a Boolean lattice 2(sup N) whereas the lattice of real questions is shown to be a sublattice of the free distributive lattice FD(N) = 2(sup 2(sup N)). Thus there does not exist a one-to-one mapping of assertions to questions, there is no reflection symmetry between the two spaces, and questions in general do not possess unique complements. Last, with these lattice structures in mind, I discuss the relationship between probability, relevance and entropy.

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

    The project More With Thermal Energy Storage (MMB, abbreviated in Dutch) focuses on knowledge gaps and potential opportunities regarding open systems. The main questions to be answered are: (1) What effects (hydrological, thermal, microbiological and chemical) occur in the soil system by application of thermal energy storage; (2) Which technical options are available for a sustainable integration of thermal energy storage in the water and energy chain?; (3) Is it possible to achieve multiple objectives by using smart combinations? The project is organized in different work packages. In work package 2, the effects of individual and collective thermal energy storage storage systems on subsoils and the environment are determined. In work package 3 the opportunities for thermal energy storage and soil remediation are examined, while in work package 4 the focus is on new sustainable combinations of heat and cold storage. Work package 1 is the umbrella part where communication and policy of and participation in MMB are the main subjects. The aim of this literature survey is to search for knowledge that is available worldwide on the effects of heat and cold storage and the possibilities to combine this technology with controlling contaminants in soil and groundwater [Dutch] Het project Meer Met Bodemenergie (MMB) richt zich op het invullen van kennisleemtes en mogelijke kansen ten aanzien van open systemen.

    Addressing the question what the probability is of an anthropogenically induced change in the climate, leads to a number of other, underlying questions. These questions, which deal with the characteristics of climate, of climatic change, and of probabilistic statements on climatic change, should be addressed first. The long-term objective of the underlying study, i.e. a quantitative assessment of the risks and opportunities of the predicted climatic change, sets the context against which of those questions should be answered. In addition, this context induces extra questions, i.e. about the characteristics of risk.

Yet if we follow Heidegger's analysis......, by doing so, we will in the end realize two important things.

    Samman, Mouna Liliane

    1993-03-01

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

  16. The Role Of Gender In Asking Questions At Cool Stars 18 And 19

    2016-12-01

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

    2017-09-01

    Pulp regeneration and its clinical translation into regenerative endodontic procedures are receiving increasing research attention, leading to significant growth of the published scientific and clinical literature within these areas. Development of research strategies, which consider patient-, clinician-, and scientist-based outcomes, will allow greater focus on key research questions driving more rapid clinical translation. Three key areas of focus for these research questions should include cells, signaling, and infection/inflammation. A translational pathway is envisaged in which clinical approaches are increasingly refined to provide regenerative endodontic protocols that are based on a robust understanding of the physiological processes and events responsible for the normal secretion, structure, and biological behavior of pulpal tissue.

    CERN Document Server

    Hoehn, Philipp A

    2016-01-01

    We reconstruct the explicit formalism of qubit quantum theory from elementary rules on an observer's information acquisition. Our approach is purely operational: we consider an observer O interrogating a system S with binary questions and define S's state as O's `catalogue of knowledge' about S; no ontic assumptions are necessary. From the rules we derive the state spaces for N qubits and show that (a) they coincide with the set of density matrices over N qubit Hilbert spaces; (b) states evolve unitarily under the group $\\rm{PSU}(2^N)$ according to the von Neumann evolution equation; and (c) the binary questions by means of which O interrogates the systems corresponds to projective measurements on Pauli operators with outcome probabilities given by the Born rule. Besides offering a novel conceptual perspective on qubit quantum theory, the reconstruction also unravels new structural insights. Namely, we show that, in a quadratic information measure, (d) qubits satisfy informational complementarity inequalities...

    Shi, J.; Knight, Jennifer K.; Chun, Hyonho; Guild, Nancy A.; Martin, Jennifer M.

    2017-01-01

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

    Objectives. Characterize the skills and abilities required for department chairs, identify development needs, and then create AACP professional development programs for chairs. Methods. A 30-question electronic survey was sent to AACP member department chairs related to aspects of chairing an academic department. Results. The survey identified development needs in the leadership, management, and personal abilities required for effective performance as department chair. The information was used to prioritize topics for subsequent AACP development programs. Subsequent programs conducted at AACP Interim and Annual Meetings were well attended and generally received favorable reviews from participants. A list of development resources was placed on the AACP website. Conclusions. This ongoing initiative is part of an AACP strategy to identify and address the professional development needs of department chairs. Survey results may also inform faculty members and other academic leaders about the roles and responsibilities of department chairs. PMID:22919099

  10. Addressing submarine geohazards through scientific drilling

    Science.gov (United States)

    Camerlenghi, A.

    2009-04-01

    Natural submarine geohazards (earthquakes, volcanic eruptions, landslides, volcanic island flank collapses) are geological phenomena originating at or below the seafloor leading to a situation of risk for off-shore and on-shore structures and the coastal population. Addressing submarine geohazards means understanding their spatial and temporal variability, the pre-conditioning factors, their triggers, and the physical processes that control their evolution. Such scientific endeavour is nowadays considered by a large sector of the international scientific community as an obligation in order to contribute to the mitigation of the potentially destructive societal effects of submarine geohazards. The study of submarine geohazards requires a multi-disciplinary scientific approach: geohazards must be studied through their geological record; active processes must be monitored; geohazard evolution must be modelled. Ultimately, the information must be used for the assessment of vulnerability, risk analysis, and development of mitigation strategies. In contrast with the terrestrial environment, the oceanic environment is rather hostile to widespread and fast application of high-resolution remote sensing techniques, accessibility for visual inspection, sampling and installation of monitoring stations. Scientific Drilling through the IODP (including the related pre site-survey investigations, sampling, logging and in situ measurements capability, and as a platform for deployment of long term observatories at the surface and down-hole) can be viewed as the centre of gravity of an international, coordinated, multi-disciplinary scientific approach to address submarine geohazards. The IODP Initial Science Plan expiring in 2013 does not address openly geohazards among the program scientific objectives. Hazards are referred to mainly in relation to earthquakes and initiatives towards the understanding of seismogenesis. Notably, the only drilling initiative presently under way is the

    Harwood, Jeremy J

    2016-01-01

    Current and future continuum surveys being undertaken by the new generation of radio telescopes are now poised to address many important science questions, ranging from the earliest galaxies, to the physics of nearby AGN, as well as potentially providing new and unexpected discoveries. However, how to efficiently analyse the large quantities of data collected by these studies in order to maximise their scientific output remains an open question. In these proceedings we present details of the surveys module for the Broadband Radio Astronomy Tools (BRATS) software package which will combine new observations with existing multi-frequency data in order to automatically analyse and select sources based on their spectrum. We show how these methods can been applied to investigate objects observed on a variety of spatial scales, and suggest a pathway for how this can be used in the wider context of surveys and large samples.

  14. From Question Answering to Visual Exploration

    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.

    How does a teacher use questioning effectively? This workshop will focus on writing those questions that engage students, spark their curiosity, help recap material, give you insight into their thinking, or help them learn critical ideas in physics. We will focus on ``peer instruction'' -- a research-tested method of requiring students to discuss challenging questions with one another. We will investigate the surprising power of multiple-choice questions to achieve critical thinking skills. Finally, we will look at writing questions that align with our goals for students, discuss the elements of effective questions, and practice writing questions and work on improving them.

    2009-01-01

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

    This naturalistic study integrates specific `question moments' into lesson plans to increase pupils' classroom interactions. A range of tools explored students' ideas by providing students with opportunities to ask and write questions. Their oral and written outcomes provide data on individual and group misunderstandings. Changes to the schedule of lessons were introduced to explore these questions and address disparities. Flexible lesson planning over 14 lessons across a 4-week period of high school chemistry accommodated students' contributions and increased student participation, promoted inquiring and individualised teaching, with each teaching strategy feeding forward into the next.

    Brigden, M L

    1995-11-01

    More than half of all cancer patients use some form of alternative treatment during the course of their illness. Alternative therapies are often started early in patients' illness, and their use is frequently not acknowledged to health care professionals. Some alternative therapies are harmful, and their promoters may be fraudulent. Persons who try alternative cancer therapies may not be poorly educated but may ultimately abandon conventional treatment. Recent attention has focused on aspects of questionable therapies that make these treatments attractive to patients and that may be perceived as being deficient in the practice of conventional health care professionals. Physicians with patients with cancer should always make sure that unproven therapies are discussed early in the therapeutic relationship. They should also attempt to be aware of alternative therapies that are in vogue in their particular geographic area.

    2010-01-01

    Full Text Available The main intention of the work that deals with the Nicolo Machiavelli thought is to point out the obvious paradox between the high political goal and the legitimating of all possible means for its realization. Are evil deeds inevitable in the sphere of politics and under what circumstances the immorality contained in political acts could be transformed into common good? The text asks additional questions such as about the accomplishments of ambitious political projects, the relationship among the ideologist and the representative of political power, the transformations of the means into the ends, the use of violence and indoctrination in political acts, revolutionary and evolutionary political methods, etc. The author claims that political technologies recommended by Machiavelli basically haven't diminished, but have taken on more modern and more adequate forms.

    2016-12-01

    On 15 February, 2013, a 15 m diameter asteroid entered the Earth's atmosphere over Russia. The resulting shockwave injured nearly 1500 people, and incurred 33 million (USD) in infrastructure damages. The Chelyabinsk meteor served as a forceful demonstration of the threat posed to Earth by the hundreds of potentially hazardous objects (PHOs) that pass near the Earth every year. Although no objects have yet been discovered on an impact course for Earth, an impact is virtually statistically guaranteed at some point in the future. While many impactor deflection technologies have been proposed, humanity has yet to demonstrate the ability to divert an impactor when one is found. Developing and testing any single proposed technology will require significant research time and funding. This leaves open an obvious question - towards which technologies should funding and research be directed, in order to maximize our preparedness for when an impactor is eventually found? To help answer this question, we have created a detailed framework for analyzing various deflection technologies and their effectiveness. Using an n-body integrator (REBOUND), we have simulated the attempted deflections of a population of Earth-impacting objects with a variety of velocity perturbations (∂Vs), and measured the effects that these perturbations had on impact probability. We then mapped the ∂Vs applied in the orbital simulations to the technologies capable of achieving those perturbations, and analyzed which set of technologies would be most effective at preventing a PHO from impacting the earth. As a final step, we used the results of these simulations to train a machine learning algorithm. This algorithm, combined with a simulated PHO population, can predict which technologies are most likely to be needed. The algorithm can also reveal which impactor observables (mass, spin, orbit, etc.) have the greatest effect on the choice of deflection technology. These results can be used as a tool to

    Although forms of address are widely used in textual and other types of disclosure,empirical evidence of their effects is rare.China provides a unique setting in which to test the economic consequences of the forms of address used in audit reports.From 2003 to 2011,about 60%of auditors surveyed addressed their clients by their real names in audit opinions,while the others used honorifics.Based on a sample of Chinese audit opinions,I report the following findings.First,the announcement of an audit opinion that uses the client’s real name elicits a greater market response than the announcement of an opinion featuring an honorific form of address.Second,the effects of real-name forms of address are stronger in firms with weak board governance.Third,the association between audit fees and audit risk factors,such as loss-making,is stronger in firms that are addressed by their real names in audit reports.I conclude from these findings that the forms of address used in audit opinions may reveal private information on audit quality.The results of this study are consistent with the power-solidarity effect described by sociolinguists.

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

  11. Addressing psychiatric comorbidity.

    Woody, G E; McLellan, A T; O'Brien, C P; Luborsky, L

    1991-01-01

    Research studies indicate that addressing psychiatric comorbidity can improve treatment for selected groups of substance-abusing patients. However, the chances for implementing the necessary techniques on a large scale are compromised by the absence of professional input and guidance within programs. This is especially true in public programs, which treat some of the most disadvantaged, disturbed, and socially destructive individuals in the entire mental health system. One starting point for upgrading the level of knowledge and training of staff members who work in this large treatment system could be to develop a better and more authoritative information dissemination network. Such a system exists in medicine; physicians are expected to read appropriate journals and to guide their treatment decisions using the data contained in the journals. Standards of practice and methods for modifying current practice are within the tradition of reading new facts, studying old ones, and comparing treatment outcome under different conditions with what is actually being done. No such general system of information-gathering or -sharing exists, particularly in public treatment programs. One of the most flagrant examples of this "educational shortfall" can be found among those methadone programs that adamantly insist on prescribing no more than 30 to 35 mg/day for all patients, in spite of the overwhelming evidence that these dose levels generally are inadequate. In some cases, program directors are unaware of studies that have shown the relationship between dose and outcome. In other cases, they are aware of the studies but do not modify their practices accordingly. This example of inadequate dosing is offered as an example of one situation that could be improved by adherence to a system of authoritative and systematic information dissemination. Many issues in substance abuse treatment do not lend themselves to information dissemination as readily as that of methadone dosing

    AMY.B.M.TSUI thinks that most of the interactive learning starts with the teachers ’questioning. Richard and Lock-art (1994) think that the proper questioning can help the students to acquire the second language. Jin Chuanbao ( 1997) even thinks that the questioning process of the teachers should become the core of the class. Though almost all of the teachers are ques-tioning, they know little about the questioning strategies. In this case, it is urgent to study this subject. The present study reveals some problems of four teachers’questioning strategies in Junior Middle School. I hope some helpful ideas can be found in the thesis.

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

  8. Is Cyberbullying a Stand Alone Construct? Using Quantitative Analysis to Evaluate a 21st Century Social Question

    Directory of Open Access Journals (Sweden)

    Ryan Randa

    2015-03-01

    Full Text Available Using a subsample of the 2009 National Crime Victimization Survey, School Crime Supplement (NCVS-SCS, the present study explores the nature of the relationship between cyberbullying and traditional bullying victimization among students aged 12–18. One question of particular interest in the recent cyberbullying literature regards the classification of cyberbullying relative to traditional school yard bullying. As is the case in the cyber victimization literature in general, the question has become whether cyberbullying is an extension of traditional bullying or whether it is a unique independent phenomenon. Using the available data we attempt to address this question by exploring cyberbullying victimization as a standalone construct. Results of exploratory factor analyses suggest that cyberbullying victimization is both interlaced with traditional bullying modalities, and experienced as a unique phenomenon. Our results contribute a 21st century texture and dimension to the traditional construct.

  9. Enhancing Curiosity Using Interactive Simulations Combined with Real-Time Formative Assessment Facilitated by Open-Format Questions on Tablet Computers

    CERN Document Server

    Kowalski, F V

    2013-01-01

    Students' curiosity often seems nearly nonexistent in a lecture setting; we discuss a variety of possible reasons for this, but it is the instructor who typically poses questions while only a few students, usually the better ones, respond. As we have developed and implemented the use of InkSurvey to collect real-time formative assessment, we have discovered that it can serve in an unanticipated role: to promote curiosity in engineering physics undergraduates. Curiosity often motivates creative, innovative people. To encourage such curiosity, we solicit questions submitted real-time via InkSurvey and pen-enabled mobile devices (Tablet PCs) in response to interactive simulations (applets) run either before or in class. This provides students with practice in asking questions, increases metacognition, and serves as a rich springboard from which to introduce content and/or address misconceptions. We describe the procedure for measuring curiosity and results from applying this method in a junior level electromagne...

    2016-01-01

    We discuss a study to evaluate the extent to which free-response questions could be approximated by multiple-choice equivalents. Two carefully designed research-based multiple-choice questions were transformed into a free-response format and administered on the final exam in a calculus-based introductory physics course. The original multiple-choice questions were administered in another similar introductory physics course on final exam. Findings suggest that carefully designed multiple-choice questions can reflect the relative performance of the free-response questions while maintaining the benefits of ease of grading and quantitative analysis, especially if the different choices in the multiple-choice questions are weighted to reflect the different levels of understanding that students display.

    Rau, P L; Salvendy, G

    2001-03-15

    The aim was to design a human-centred electronic mail (e-mail) address system based on networking technology and cognitive ergonomics. Based on the background literature and the results of users' survey, a conceptual model is developed for designing e-mail addresses. This model consists of e-mail address components of formats, domain length, meaningfulness, orientation and information type pertaining to recall, information association and categorization. Five hypotheses were proposed to test the conceptual model, and four experiments were conducted with 85 participants to test the hypotheses. The dependent variables were performance time, error rate and degree of satisfaction, and the independent variables were components of the e-mail addresses. The main results indicate that for a recall task, significantly lower total performance time (26.2%) and error rate (75%) were found for the hybrid formats (digits and letters) than for the letter format, and up to four characters was the best single domain length. For an information association task, embedding both geographical and organizational information significantly decreased the response time (10.9%) in comparison with only embedding organizational information. For a categorization task, embedding both geographical information and organizational information significantly decreased response time (40.7%) in comparison with only embedding organizational information. This research demonstrates the importance of human-centred design and provides guidelines in effectively designing e-mail addresses.

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

    2016-01-01

    Address-resolution protocol (ARP) is an important protocol of data link layers that aims to obtain the corresponding relationship between Internet Protocol (IP) and Media Access Control (MAC) addresses. Traditional ARPs (address-resolution and neighbor-discovery protocols) do not consider the existence of malicious nodes, which reveals destination addresses in the resolution process. Thus, these traditional protocols allow malicious nodes to easily carry out attacks, such as man-in-the-middle attack and denial-of-service attack. To overcome these weaknesses, we propose an anonymous-address-resolution (AS-AR) protocol. AS-AR does not publicize the destination address in the address-resolution process and hides the IP and MAC addresses of the source node. The malicious node cannot obtain the addresses of the destination and the node which initiates the address resolution; thus, it cannot attack. Analyses and experiments show that AS-AR has a higher security level than existing security methods, such as secure-neighbor discovery.

  20. A derivational rephrasing experiment for question answering

    CERN Document Server

    Jacquemin, Bernard

    2010-01-01

    In Knowledge Management, variations in information expressions have proven a real challenge. In particular, classical semantic relations (e.g. synonymy) do not connect words with different parts-of-speech. The method proposed tries to address this issue. It consists in building a derivational resource from a morphological derivation tool together with derivational guidelines from a dictionary in order to store only correct derivatives. This resource, combined with a syntactic parser, a semantic disambiguator and some derivational patterns, helps to reformulate an original sentence while keeping the initial meaning in a convincing manner This approach has been evaluated in three different ways: the precision of the derivatives produced from a lemma; its ability to provide well-formed reformulations from an original sentence, preserving the initial meaning; its impact on the results coping with a real issue, ie a question answering task . The evaluation of this approach through a question answering system shows...

  1. Methodological questions in studying consonant acquisition

    Science.gov (United States)

    Edwards, Jan; Beckman, Mary E.

    2009-01-01

    Consonant mastery is one of the most widely used metrics of typical phonological acquisition and of phonological disorder. Two fundamental methodological questions concerning research on consonant acquisition are (1) how to elicit a representative sample of productions and (2) how to analyse this sample once it has been collected. This paper address these two questions by reviewing relevant aspects of experience in evaluating word-initial consonant accuracy from transcriptions of isolated-word productions elicited from 2- and 3-year-olds learning four different first languages representing a telling range of consonant systems (English, Cantonese, Greek, Japanese). It is suggested that both researchers and clinicians should consider a number of different item-related factors, such as phonotactic probability and word length, when constructing word lists to elicit consonant productions from young children. This study also proposes that transcription should be supplemented by acoustic analysis and the perceptual judgements of naïve listeners. PMID:19031192

    2010-12-01

    Are debatable scientific questions debatable? In 2000, the physicist-philosopher John Ziman posed this pithy—and crucial—question. He noted that scientists were at a disadvantage in public debate, because the rules of engagement are different in scientific discourse than in public discourse in ways that make it difficult for scientists to ‘win’ public arguments, even when the facts are on their side. In this paper, I revisit Ziman’s arguments in light of the difficulties that climate scientists have had in communicating the reality and gravity of global warming. In addition to the problem posed by Ziman, I also address the role of organized disinformation in further increasing the challenges that climate scientists face.

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

    Science.gov (United States)

    Biggers, Mandy

    2017-01-01

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

  5. Reclaiming unused IPv4 addresses

    CERN Multimedia

    IT Department

    2016-01-01

    As many people might know, the number of IPv4 addresses is limited and almost all have been allocated (see here and here for more information).   Although CERN has been allocated some 340,000 addresses, the way these are allocated across the site is not as efficient as we would like. As we face an increasing demand for IPv4 addresses with the growth in virtual machines, the IT Department’s Communication Systems Group will be reorganising address allocation during 2016 to make more efficient use of the IPv4 address ranges that have been allocated to CERN. We aim, wherever possible, to avoid giving out fixed IP addresses, and have all devices connected to the campus network obtain an address dynamically each time they connect. As a first stage, starting in February, IP addresses that have not been used for more than 9 months will be reclaimed. No information about the devices concerned will be deleted from LANDB, but a new IP address will have to be requested if they are ever reconnected to t...

    Script Concordance Test (SCT) is a new assessment tool that reliably assesses clinical reasoning skills. Previous descriptions of developing SCT-question banks were merely subjective. This study addresses two gaps in the literature: 1) conducting the first phase of a multistep validation process of SCT in Plastic Surgery, and 2) providing an objective methodology to construct a question bank based on SCT. After developing a test blueprint, 52 test items were written. Five validation questions were developed and a validation survey was established online. Seven reviewers were asked to answer this survey. They were recruited from two countries, Saudi Arabia and Canada, to improve the test's external validity. Their ratings were transformed into percentages. Analysis was performed to compare reviewers' ratings by looking at correlations, ranges, means, medians, and overall scores. Scores of reviewers' ratings were between 76% and 95% (mean 86% ± 5). We found poor correlations between reviewers (Pearson's: +0.38 to -0.22). Ratings of individual validation questions ranged between 0 and 4 (on a scale 1-5). Means and medians of these ranges were computed for each test item (mean: 0.8 to 2.4; median: 1 to 3). A subset of test items comprising 27 items was generated based on a set of inclusion and exclusion criteria. This study proposes an objective methodology for validation of SCT-question bank. Analysis of validation survey is done from all angles, i.e., reviewers, validation questions, and test items. Finally, a subset of test items is generated based on a set of criteria.

  8. Why and how? Addressing to the two most pertinent questions about pharmacovigilance in Ayurveda.

    Rastogi, Sanjeev

    2011-01-01

    Pharmacovigilance is the outcome of a natural and implied willingness of a physician to ensure safety to his patient. This is a discipline in medicine which pragmatises the principle of first do no harm towards a wider and systematic application in clinical practice. It is however important to understand that despite of its huge potential in ensuring a safe practice of medicine through knowledge of avoidable causes of adversities, its path has never been easy. Applying principles of pharmacovigilance into the realm of traditional medicine particularly to Ayurveda is even more difficult for the issues of why and how of pharmacovigilance in light of historical practice and anecdotal evidences of safety in Ayurveda. Application of pharmacovigilance in Ayurveda thereby demands a careful and thoughtful observation of its needs and its methods of application in order to to maximize its impacts to ensure the patient safety to every extent possible.

  9. The Energy-GDP Nexus. Addressing an old question with new methods

    Energy Technology Data Exchange (ETDEWEB)

    Coers, R.J.; Sanders, M.

    2012-01-15

    This paper reassesses the causal relationship between per capita energy use and gross domestic product, while controlling for capital and labour (productivity) inputs in a panel of 30 OECD countries over the past 40 years. The paper uses panel unit root and cointegration testing and specifies an appropriate vector error correction model to analyse the nexus between income and energy use. In doing so we contribute to an old debate using modern tools that shed a new light. There is some evidence that over the short-run bidirectional causality exists. Our results also show a strong unidirectional causality running from capital formation and GDP to energy usage. In the long run the reverse causality, found in recent work, is lost. We then show that we can reproduce these earlier results in our data if we reproduce a slightly misspecified model for the Engle-Granger two-step procedure used in these earlier papers. Our findings thus imply that results are very sensitive to model misspecification and careful testing of specifications is required. Our results have some strong policy implications. They suggest that policies aimed at reducing energy usage or promoting energy efficiency are not likely to have a detrimental effect on economic growth, except over the very short run.

  10. MERGERS AND ACQUISITIONS IN THE GREEK BANKING SECTOR ADDRESSING THE PROFITABILITY QUESTION

    Directory of Open Access Journals (Sweden)

    Vassilis Chouliaras

    2013-01-01

    Full Text Available The wave of mergers and acquisitions of financial institutions which was observed in the United States and Europe in the 1980s and 1990s seems to have affected the Greek banking market by the end of the 1990s. The result was the emergence of new significant players in the market. Despite the fact that scale economies should lead to the improvement of their efficiency, this fact was not confirmed by empirical research and, moreover in several cases there has been an adverse effect. We are focus on financial statement analysis by examining the profitability and performance ratios. Mergers and acquisitions in the Greek banking system contributed to an increase in profitability of banks but they did not lead to improvement to their efficiency. It is an undeniable fact that the development and expansion of banks had a positive effect on the markets, resulting in the attraction of new capital which improved their capital sufficiency and of course on their extroversion, their internationalization and their successful expansion to other markets-particularly to Balkan countries.

  11. Is exogenous hydrogen sulfide a relevant tool to address physiological questions on hydrogen sulfide?

    Science.gov (United States)

    Haouzi, Philippe

    2016-07-15

    This review challenges the use of solutions of dissolved exogenous H2S in the literature as a tool to determine the potential physiological functions of endogenous H2S as well as its putative therapeutic applications. Our major point of contention is that solutions of dissolved H2S are used in vitro at concentrations, within the high microM range, which are above the concentrations of dissolved H2S found in blood and tissues during lethal H2S exposure in vivo. In addition, since the levels of toxicity are extremely variable among cell types, a property that is seldom acknowledged, the physiological relevance of data obtained after local or in-vitro administrations of H2S at concentrations of few microM is far from certain. Conversely, the rate of disappearance of the dissolved pool of H2S in the body (being trapped or oxidized), which we found to be at least of several micromoles/kg/min, is so rapid in vivo that if relatively low quantities of H2S, i.e. few micromoles for instance, are administered, no change in H2S concentrations in the body is to be expected, unless toxic levels are used. Protocols looking at the effects of compounds slowly releasing H2S must also resolve a similar conundrum, as their effects must be reconciled with the unique ability of the blood and tissues to get rid of H2S and the steepness of the dose-toxic effects relationship. Only by developing a comprehensive framework in which H2S metabolism and toxicity will be used as a rationale to justify any experimental approach will we be able to bring definitive evidence supporting a protective role for exogenous H2S, if any, and its putative function as an endogenous mediator.

  12. Addressing health inequalities by using Structural Funds. A question of opportunities.

    Neagu, Oana Maria; Michelsen, Kai; Watson, Jonathan; Dowdeswell, Barrie; Brand, Helmut

    2017-03-01

    Making up a third of the EU budget, Structural and Investment Funds can provide important opportunities for investing in policies that tackle inequalities in health. This article looks back and forward at the 2007-2013 and 2014-2020 financial periods in an attempt to inform the development of health equity as a strand of policy intervention under regional development. It combines evidence from health projects funded through Structural Funds and a document analyses that locates interventions for health equity under the new regulations. The map of opportunities has changed considerably since the last programming period, creating more visibility for vulnerable groups, social determinants of health and health systems sustainability. As the current programming period is progressing, this paper contributes to maximizing this potential but also identifying challenges and implementation gaps for prospective health system engagement in pursuing health equity as part of Structural Funds projects. The austerity measures and their impact on public spending, building political support for investments as well as the difficulties around pursuing health gains as an objective of other policy areas are some of the challenges to overcome. European Structural and Investment Funds could be a window of opportunity that triggers engagement for health equity if sectors adopt a transformative approach and overcome barriers, cooperate for common goals and make better use of the availability of these resources.

    2011-01-01

    This paper is a short survey on four basic questions on Artin-Tits groups: the torsion, the center, the word problem, and the cohomology ($K(\\pi,1)$ problem). It is also an opportunity to prove three new results concerning these questions: (1) if all free of infinity Artin-Tits groups are torsion free, then all Artin-Tits groups will be torsion free; (2) If all free of infinity irreducible non-spherical type Artin-Tits groups have a trivial center then all irreducible non-spherical type Artin-Tits groups will have a trivial center; (3) if all free of infinity Artin-Tits groups have solutions to the word problem, then all Artin-Tits groups will have solutions to the word problem. Recall that an Artin-Tits group is free of infinity if its Coxeter graph has no edge labeled by $\\infty$.

    2014-01-01

    This discussion paper forms an insightful addition to the synesthesia literature. Accompanying a steep increase in recent publications on synesthesia, it helps remedy the conspicuous paucity of mechanistic process models explaining the condition. The paper furthermore addresses what is arguably among the most interesting questions: Why do most synesthetes *not* get confused by their additional sensations? This is particularly interesting when phrased in a broader context: What are the mechanisms for deciding which of the sensations we experience reflect something "real" (phenomena in the outside world) and which reflect something that is "not real" (internally generated and private phenomena).

  15. Why worship? Revisiting a fundamental liturgical question

    Directory of Open Access Journals (Sweden)

    Johan Cilliers

    2009-03-01

    Full Text Available In this article the fundamental liturgical question as to the motive and intention of worship is addressed within the framework of four related liturgical tensions, namely between being and becoming, between time and space, between awe and expression, and between laughter and lament. In order to do this, some classical voices from the past are listened to, for instance, Schleiermacher, Kierkegaard, Moltmann, Tillich, Otto, Bakhtin and Buber, but more contemporary views are also considered. These four tensions are described in the light of the key terms: ‘already’ and ‘not yet’, and some implications for present-day liturgical practices are drawn.

Recent research points to cognitive biases that may occur in citizens’ perceptions of performance of public services, but we know little about...... possible biases in the collection of these data. This shortcoming is addressed by investigating the priming and context effects that can arise from the structure of citizen surveys—for example from the question order in the survey.

  20. Questioning the Patient, Questioning Hippocrates: Rufus of Ephesus and the Pursuit of Knowledge.

    Science.gov (United States)

    Letts, Melinda

    2016-01-01

    Rufus of Ephesus' short treatise, Quaestiones Medicinales, the only ancient medical work that takes as its topic the dialogue between doctor and patient, has usually been seen as a procedural practical handbook serving an essentially operational purpose. In this paper I argue that the treatise, with its insistent message that doctors cannot properly understand and treat illnesses unless they supplement their own knowledge by questioning patients, and its remarkable appreciation of the singularity of each patient's experience, shows itself to be no mere handbook but a work addressing the place of questioning in the clinical encounter. I illustrate some of the differences between Rufus' conceptualisation of the relevance and use of questioning and that which can be seen in the theoretical and descriptive writings of Galen and in the Hippocratic corpus, and show how apparent resonances with some of the preoccupations of modern Western healthcare can be used judiciously to elucidate the significance of those differences.

  3. Explaining errors in children's questions.

    Science.gov (United States)

    Rowland, Caroline F

    2007-07-01

    The ability to explain the occurrence of errors in children's speech is an essential component of successful theories of language acquisition. The present study tested some generativist and constructivist predictions about error on the questions produced by ten English-learning children between 2 and 5 years of age. The analyses demonstrated that, as predicted by some generativist theories [e.g. Santelmann, L., Berk, S., Austin, J., Somashekar, S. & Lust. B. (2002). Continuity and development in the acquisition of inversion in yes/no questions: dissociating movement and inflection, Journal of Child Language, 29, 813-842], questions with auxiliary DO attracted higher error rates than those with modal auxiliaries. However, in wh-questions, questions with modals and DO attracted equally high error rates, and these findings could not be explained in terms of problems forming questions with why or negated auxiliaries. It was concluded that the data might be better explained in terms of a constructivist account that suggests that entrenched item-based constructions may be protected from error in children's speech, and that errors occur when children resort to other operations to produce questions [e.g. Dabrowska, E. (2000). From formula to schema: the acquisition of English questions. Cognitive Liguistics, 11, 83-102; Rowland, C. F. & Pine, J. M. (2000). Subject-auxiliary inversion errors and wh-question acquisition: What children do know? Journal of Child Language, 27, 157-181; Tomasello, M. (2003).

  7. Hypothetical constructs, hypothetical questions, and the expert witness.

    Science.gov (United States)

    Brodsky, Stanley L; Titcomb, Caroline; Sams, David M; Dickson, Kara; Benda, Yves

    2012-01-01

    Professor John Henry Wigmore in 1940 described the hypothetical question as an intolerable obstruction of truth. Since that time, the nature and application of the hypothetical question in the courtroom, as well as responses to this line of questioning during expert testimony, have been sources of controversy. Governed by legal philosophical foundations, the hypothetical construct addresses what there is, in a general sense, and what can or ought to be. Alexy (2004) has described the nature of legal philosophy as the epistemological question of what we can know. This article begins by examining the philosophical underpinnings, legal parameters, and teaching purposes of posing hypothetical queries. A social-psychological backdrop for the use of hypothetical questions is then discussed followed by a broader discussion of the hypothetical question's role in court procedures. This paper identifies hypothetical questions used in court as devices to elicit information, or as predictions that potentially change underlying factual interpretations of evidence. In particular, on cross examination hypothetical questions seek to make opposing experts assume facts that are incongruent with their conclusions or opinions. Sometimes in these situations, experts are led to re-evaluate opinions based on alternative understandings of events and behaviors. Thus, this paper's final aim is to explore a foundational understanding of hypothetical questions asked of expert witnesses with special reference to mental health issues. Options for responding to hypothetical questions on the stand are considered along the dimensions of assertiveness-passivity, compliance-resistance, and possible redefinitions of the hypothetical issues.

    1978-01-01

    The experience with gastrointestinal cancer at a single large hospital has been utilized as a "micro-model" of the experience for the country at large, and the reasons why such a comparison might be possible have been presented. The incidence of various lesions has been discussed in terms of sex, age, and race. The changing incidence of various lesions has been pointed out. Survival results have been determined for total series, for various types of operative procedures, and for various extents of disease. The comparability of survival results from this one institution and those collected from the literature have been discussed. The emergence of newer diagnostic and therapeutic measures has been highlighted. The importance of education of both patients and physicians is emphasized repeatedly by the late stage at which so many of the patients with any gastrointestinal cancer present to and are diagnosed by the physician. The educational task for all of medicine is apparent and must be faced in some effective fashion.

JAXA's Akatsuki orbiter will soon begin collecting unique and valuable observations in April 2016 which will increase our knowledge, but other measurements required to answer these questions require careful and sustained observations within the atmosphere and from surface based stations. Some of these measurements should and can be made by large missions such as Venera-D, Venus Climate Mission or the Venus Flagship Design Reference Mission which have been studied in recent years, but some have not been addressed in such studies. Many new missions to Venus are being developed or conceived and it is important to keep the key questions about Venus in focus.

  2. Protein Electrochemistry: Questions and Answers.

    Science.gov (United States)

    Fourmond, V; Léger, C

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

  7. Semi-automated categorization of open-ended questions

    Directory of Open Access Journals (Sweden)

    Matthias Schonlau

    2016-08-01

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

    2016-06-01

    In this paper we discuss the main ethical challenges related to the conduct of medicine quality surveys and make suggestions on how to address them. Most evidence-based information regarding medicine quality derives from surveys. However, existing research ethical guidelines do not provide specific guidance for medicine quality surveys. Hence, those conducting surveys are often left wondering how to judge what counts as best practice. A list of the main ethical challenges in the design and conduct of surveys is presented. It is vital that the design and conduct of medicine quality surveys uphold moral and ethical obligations and analyse the ethical implications and consequences of such work. These aspects include the impact on the local availability of and access to medicines; the confidentiality and privacy of the surveyors and the surveyed; questions as to whether outlet staff personnel should be told they are part of a survey; the need of ethical and regulatory approvals; and how the findings should be disseminated. Medicine quality surveys should ideally be conducted in partnership with the relevant national Medicine Regulatory Authorities. An international, but contextually sensitive, model of good ethical practice for such surveys is needed. © 2016 The Authors.

  3. Multi-Factor Duplicate Question Detection in Stack Overflow

    Institute of Scientific and Technical Information of China (English)

    张芸; David Lo; 夏鑫; 孙建伶

    2015-01-01

    Stack Overflow is a popular on-line question and answer site for software developers to share their experience and expertise. Among the numerous questions posted in Stack Overflow, two or more of them may express the same point and thus are duplicates of one another. Duplicate questions make Stack Overflow site maintenance harder, waste resources that could have been used to answer other questions, and cause developers to unnecessarily wait for answers that are already available. To reduce the problem of duplicate questions, Stack Overflow allows questions to be manually marked as duplicates of others. Since there are thousands of questions submitted to Stack Overflow every day, manually identifying duplicate questions is a di昋cult work. Thus, there is a need for an automated approach that can help in detecting these duplicate questions. To address the above-mentioned need, in this paper, we propose an automated approach named DUPPREDICTOR that takes a new question as input and detects potential duplicates of this question by considering multiple factors. DUPPREDICTOR extracts the title and description of a question and also tags that are attached to the question. These pieces of information (title, description, and a few tags) are mandatory information that a user needs to input when posting a question. DUPPREDICTOR then computes the latent topics of each question by using a topic model. Next, for each pair of questions, it computes four similarity scores by comparing their titles, descriptions, latent topics, and tags. These four similarity scores are finally combined together to result in a new similarity score that comprehensively considers the multiple factors. To examine the benefit of DUPPREDICTOR, we perform an experiment on a Stack Overflow dataset which contains a total of more than two million questions. The result shows that DUPPREDICTOR can achieve a recall-rate@20 score of 63.8%. We compare our approach with the standard search engine of Stack

    To address the academic gap (or lack of adequate training and programs) between 4- and 6-year pharmacy programs and suggest methods for reducing this gap and to evaluate pharmacists' perceptions of preceptorship. We surveyed a convenience sample of 200 community pharmacists who graduated from a 4-year program who were participating in a continuing education program for clinical pharmacy as organized by the Daejeon branch of the Korea Pharmaceutical Association in 2011. Twenty-one questions were asked about the academic gap, needs for an education program, preceptorship, and medication therapy management services. International precedents were examined through a literature review to glean ideas of how to bridge the academic gap between the 4- and 6-year programs. In total, 132 pharmacists answered the survey (return rate=66.0%). The survey findings included problems caused by the academic gap, high need for an adequate education program, low acceptability of preceptorship, and the possibility of medication therapy management services. US-based, non-traditional PharmD programs and new curriculum-support training in Japan provided examples of how the academic gap has been successfully bridged. Nationwide efforts and government support are urgently required to close the academic gap, and experiential education should be included in transitional programs for 4-year pharmacy program pharmacists.

  9. Karl Mannheim’s Jewish Question

    Directory of Open Access Journals (Sweden)

    David Kettler

    2012-04-01

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

  10. Two Questions about Data-Oriented Parsing

    CERN Document Server

    Bod, R

    1996-01-01

    In this paper I present ongoing work on the data-oriented parsing (DOP) model. In previous work, DOP was tested on a cleaned-up set of analyzed part-of-speech strings from the Penn Treebank, achieving excellent test results. This left, however, two important questions unanswered: (1) how does DOP perform if tested on unedited data, and (2) how can DOP be used for parsing word strings that contain unknown words? This paper addresses these questions. We show that parse results on unedited data are worse than on cleaned-up data, although very competitive if compared to other models. As to the parsing of word strings, we show that the hardness of the problem does not so much depend on unknown words, but on previously unseen lexical categories of known words. We give a novel method for parsing these words by estimating the probabilities of unknown subtrees. The method is of general interest since it shows that good performance can be obtained without the use of a part-of-speech tagger. To the best of our knowledge...

  11. Atomic clusters with addressable complexity

    Science.gov (United States)

    Wales, David J.

    2017-02-01

    A general formulation for constructing addressable atomic clusters is introduced, based on one or more reference structures. By modifying the well depths in a given interatomic potential in favour of nearest-neighbour interactions that are defined in the reference(s), the potential energy landscape can be biased to make a particular permutational isomer the global minimum. The magnitude of the bias changes the resulting potential energy landscape systematically, providing a framework to produce clusters that should self-organise efficiently into the target structure. These features are illustrated for small systems, where all the relevant local minima and transition states can be identified, and for the low-energy regions of the landscape for larger clusters. For a 55-particle cluster, it is possible to design a target structure from a transition state of the original potential and to retain this structure in a doubly addressable landscape. Disconnectivity graphs based on local minima that have no direct connections to a lower minimum provide a helpful way to visualise the larger databases. These minima correspond to the termini of monotonic sequences, which always proceed downhill in terms of potential energy, and we identify them as a class of biminimum. Multiple copies of the target cluster are treated by adding a repulsive term between particles with the same address to maintain distinguishable targets upon aggregation. By tuning the magnitude of this term, it is possible to create assemblies of the target cluster corresponding to a variety of structures, including rings and chains.

    Full Text Available During the past two decades, there have been growing interests on developing websites to build a link between various groups of people to share their knowledge such as Google service. This kind of activity helps fast and reliable distribution of knowledge since someone disseminates a question and various people attempt to provide some responses. This paper presents a system dynamic method for investigating the relationships between various components of a benchmark site. The proposed study develops closed loop dynamic among various components of the survey and provides some necessary actions for development of such systems. The results of our survey have indicated that the new forum could end up having significant number of unanswered questions. Therefore, researchers who work for this forum are suggested to increase their skills and their response rates to reduce the rate of unanswered questions.

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

    2014-12-01

    Knowledge surveys are a type of confidence survey in which students rate their confidence in their ability to answer questions rather than answering the questions. These surveys have been discussed as a tool to evaluate student in-class or curriculum-wide learning. However, disagreement exists as to whether confidence is actually an accurate measure of knowledge. With the concomitant goals of assessing content-based learning objectives and addressing this disagreement, we present herein a pretest/posttest knowledge survey study that demonstrates a significant difference correctness on graded test questions at different levels of reported confidence in a multi-semester timeframe. Questions were organized into Bloom's taxonomy, allowing for the data collected to further provide statistical analyses on strengths and deficits in various levels of Bloom's reasoning with regard to mean correctness. Collectively, students showed increasing confidence and correctness in all levels of thought but struggled with synthesis-level questions. However, when students were only asked to rate confidence and not answer the accompanying test questions, they reported significantly higher confidence than the control group which was asked to do both. This indicates that when students do not attempt to answer questions, they have significantly greater confidence in their ability to answer those questions. Additionally, when students rate only confidence without answering the question, resolution across Bloom's levels of reasoning is lost. Based upon our findings, knowledge surveys can be an effective tool for assessment of both breadth and depth of knowledge, but may require students to answer questions in addition to rating confidence to provide the most accurate data.

  20. Some open questions in hydrodynamics

    Dyndal, Mateusz

    2014-01-01

    When speaking of unsolved problems in physics, this is surprising at first glance to discuss the case of fluid mechanics. However, there are many deep open questions that come with the theory of fluid mechanics. In this paper, we discuss some of them that we classify in two categories, the long term behavior of solutions of equations of hydrodynamics and the definition of initial (boundary) conditions. The first set of questions come with the non-relativistic theory based on the Navier-Stokes equations. Starting from smooth initial conditions, the purpose is to understand if solutions of Navier-Stokes equations remain smooth with the time evolution. Existence for just a finite time would imply the evolution of finite time singularities, which would have a major influence on the development of turbulent phenomena. The second set of questions come with the relativistic theory of hydrodynamics. There is an accumulating evidence that this theory may be relevant for the description of the medium created in high en...

    2014-06-01

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

  4. Assessing what to address in science communication

    2013-01-01

    As members of a democratic society, individuals face complex decisions about whether to support climate change mitigation, vaccinations, genetically modified food, nanotechnology, geoengineering, and so on. To inform people’s decisions and public debate, scientific experts at government agencies, nongovernmental organizations, and other organizations aim to provide understandable and scientifically accurate communication materials. Such communications aim to improve people’s understanding of the decision-relevant issues, and if needed, promote behavior change. Unfortunately, existing communications sometimes fail when scientific experts lack information about what people need to know to make more informed decisions or what wording people use to describe relevant concepts. We provide an introduction for scientific experts about how to use mental models research with intended audience members to inform their communication efforts. Specifically, we describe how to conduct interviews to characterize people’s decision-relevant beliefs or mental models of the topic under consideration, identify gaps and misconceptions in their knowledge, and reveal their preferred wording. We also describe methods for designing follow-up surveys with larger samples to examine the prevalence of beliefs as well as the relationships of beliefs with behaviors. Finally, we discuss how findings from these interviews and surveys can be used to design communications that effectively address gaps and misconceptions in people’s mental models in wording that they understand. We present applications to different scientific domains, showing that this approach leads to communications that improve recipients’ understanding and ability to make informed decisions.

  5. [Foundational questions in the beginning of clinical psychology].

    Science.gov (United States)

    Ceccarelli, Glauco

    2013-01-01

    This work proposes an initial survey on the origins of American clinical psychology between the nineteenth and twentieth century, against a backdrop of historiographical interpretation that hypothesizes a "plurality of matrices" of clinical psychology, linked to different theoretical perspectives and different socio-cultural contexts. Particular attention is focused upon the main foundational issues of the discipline, drawing from some of the writings of Lightner Witmer, to whom we owe the founding of the first "clinical psychology" for subjects in childhood characterized by "retardation or physical defects interfering with school progress"; and of a lesser-known scholar, John E.W. Wallin. Both authors, indeed, worry themselves anxious to define clinical psychology, differentiating it from other medical and psychological branches; to establish which is the field of competence of the clinical psychologist; and to outline their training and specify the aims and contents of their intervention. Attention is then addressed to the relationship psychologists-psychiatrists at the time of its emergence, making specific reference to a document of the New York Psychiatrical Society--which represents one of the first attempts to exclude clinical psychologists from the field of mental health--and reporting also on the response to this position signed by Shepherd Franz. After an allusion to the Italian situation from the 1950s to today, the article concludes by emphasizing that at least some of the basic questions that clinical psychology had to deal with at its birth are still present, though filtered through the intense debate that has taken place over the years, and consequently supporting the importance of a historical component in the training of contemporary clinical psychologists.

    Friel, Sharon; Hattersley, Libby; Ford, Laura; O'Rourke, Kerryn

    2015-09-01

    What, when, where and how much people eat is influenced by a complex mix of factors at societal, community and individual levels. These influences operate both directly through the food system and indirectly through political, economic, social and cultural pathways that cause social stratification and influence the quality of conditions in which people live their lives. These factors are the social determinants of inequities in healthy eating. This paper provides an overview of the current evidence base for addressing these determinants and for the promotion of equity in healthy eating.

To meet this goal the next generation energy workforce in the U.S., in particular those needed to support instrumentation, controls and advanced operations and maintenance, is a critical element. The workforce is aging and a new workforce pipeline, to support both current generation and new build has yet to be established. The paper reviews the challenges and some actions being taken to address this need.

  9. God in Question: Questioning as a Prerequisite for Theology

    Directory of Open Access Journals (Sweden)

    Martin Kočí

    2014-10-01

    Full Text Available There are questions that are so important that it is a pity to spoil them with answers. No doubt, the question of God is one of them. Contrary to many presuppositions, theology is not capable of providing us with the final answers in this respect. On the contrary, theology professed as fides quaerens intellectum is an ongoing struggle with questions. Modernity interrupted this paradigm of theological questioning. Theology was withdrawn from the realm of understanding and shifted to the realm of explanation. Modernity brought the univocalization of God. Nonetheless, the attempts to tackle the question of God lead to hegemonic narratives about God. Such narratives are rightly criticized in a postmodern context for their totalizing pretensions. The problem of postmodern criticism is its one-sided emphasis on the apophatic dimension of theological discourse. I propose that theology can go a step further beyond postmodernity. In order to do so, I deal with the Czech philosopher Jan Patočka, who provides an opportunity to rethink God from the perspective of questioning in a new way. Patočka’s insistence on problematicity is the main reading key of his work. In this line of though, I interpret Patočka’s student Tomáš Halík and his thesis about the necessity to take the metaphor of an unknown God into account. I argue that theology must avoid the temptation to remove God from the question and make a well-known God of him. The time has come for theologians to turn their answers back into questions and dwell with them. Bůh jako otázka: Tázání jako předpoklad teologie Některé otázky jsou tak důležité, že je škoda kazit je odpověďmi. Není pochyb, že otázka po Bohu je jednou z nich. Navzdory mnoha předpokladům, ani teologie není schopna poskytnout v tomto ohledu konečné odpovědi. Teologie pojatá jako fides quaerens intellectum je nepřetržitý nekončící zápas s otázkami. Moderna narušila toto paradigma teologick

    At present, 75% of the electricity in France is of nuclear origin. Most of French people approve this mode of energy production and agree upon the continuation of the electronuclear sector exploitation. However, as any industry, the nuclear industry produces wastes which constitute a keen preoccupation of the public opinion. The nuclear program, even at its very inception, has provided the appropriate mastering of radioactive wastes by reducing their volume, by conditioning, reprocessing and storing, expressing continually its carefulness for population protection as well as for environment defence against the radiological effects. Pursuing its policy of transparency the EDF demonstrated openness and understanding towards questions raised by anyone. This brochure gives answers to the following 17 questions: -what the nuclear wastes are, which is their origin? - what is their amount? - are the nuclear waste dangerous? - how to treat the nuclear wastes? - are the radioactive waste storage sure? - is the nuclear waste transportation sure? - are these solutions sure? - why searches for long-lived radioactive wastes? - what is transmutation? - shall we bequeath to the next generations our nuclear wastes? - are there particular problems in nuclear power plant decommissioning? - what the wastes issued from decommissioning become? - are the costs of reprocessing and decommissioning taken into account in the price of the kWh? - were the nuclear wastes taken into account since the nuclear program inception? - who manages the nuclear wastes? - why France accepted the reprocessing of nuclear wastes produced in foreign countries? - is there an international policy for nuclear wastes?.

  11. A Reflection on Teacher Questioning Types

    2011-07-01

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

  14. Geothermal industry employment: Survey results & analysis

    Energy Technology Data Exchange (ETDEWEB)

    2005-09-01

    The Geothermal Energy Association (GEA) is ofteh asked about the socioeconomic and employment impact of the industry. Since available literature dealing with employment involved in the geothermal sector appeared relatively outdated, unduly focused on certain activities of the industry (e.g. operation and maintenance of geothermal power plants) or poorly reliable, GEA, in consultation with the DOE, decided to conduct a new employment survey to provide better answers to these questions. The main objective of this survey is to assess and characterize the current workforce involved in geothermal activities in the US. Several initiatives have therefore been undertaken to reach as many organizations involved in geothermal activities as possible and assess their current workforce. The first section of this document describes the methodology used to contact the companies involved in the geothermal sector. The second section presents the survey results and analyzes them. This analysis includes two major parts. The first part analyzes the survey responses, presents employment numbers that were captured and describes the major characteristics of the industry that have been identified. The second part of the analysis estimates the number of workers involved in companies that are active in the geothermal business but did not respond to the survey or could not be reached. Preliminary conclusions and the study limits and restrictions are then presented. The third section addresses the potential employment impact related to manufacturing and construction of new geothermal power facilities. Indirect and induced economic impacts related with such investment are also investigated.

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

  20. Evaluative Conditioning: The "How" Question.

    Science.gov (United States)

    Jones, Christopher R; Olson, Michael A; Fazio, Russell H

    2010-01-01

    Evaluative conditioning (EC) refers to attitude formation or change toward an object due to that object's mere co-occurrence with another valenced object or objects. This chapter focuses on the "how" question, that is, the question of what cognitive processes intervene between mere co-occurrence and attitude formation or change. Though EC has typically been thought of as occurring through a single, albeit contentious, mechanism, we begin by pointing out that both the heterogeneity of EC methodologies and the abundance of inconsistent results suggest that multiple processes with different characteristics can produce EC. We describe how the earliest posited process of EC, Pavlovian conditioning or signal learning, is a valid mechanism of EC that appears to have operated in some experiments but is unlikely to have operated in others and also cannot account for various EC findings. We describe other mechanisms of EC, when they can be expected to occur, and what characteristics they have. We particularly focus our attention on a process model of EC we have recently introduced, the implicit misattribution model. Finally, we describe the implications of a multi-process view of EC, which we argue can help resolve theoretical controversies and further the application of EC as a practical intervention for influencing attitudes in various domains.

    A hydrographic survey of Sabine Lake, a broad, shallow estuary lying on the Texas-Louisiana border, was conducted in June 1996 to help address questions relating to potential environmental effects of future water demands in Texas. The use of a variety of new instruments in this study is one means by which automation is improving efficiency and effectiveness of these efforts by increasing the quality and quantity of data collected.

  3. Addressing the Language Description Deficit

    2010-01-01

    Full Text Available Well-described language features are key to successful teaching and learning, especially for achieving advanced levels of proficiency. Other measures, such as simply increasing the number of reading and listening passages in a language program alone are not enough to bring the student to a higher level in a given skill. In fact, even being present in the target culture does not suffice. Angelelli and Degueldre (2002 argue that at advanced levels, even spending time in a country where the language is spoken is not necessarily sufficient for learners: "They do not need just exposure; they need answers to questions and explanations that they can rarely get by simply being immersed in a language/ culture." Less commonly taught languages (LCTLs lack descriptions that have such answers and explanations (cf. Fotos, 2002. It is argued in this paper that corpuslinguistic analyses help to provide actual usage-based, rather than intuition-based, descriptions and explanations of language features. Such approach is illustrated through English and Turkish examples.

  5. Appearance questions can be misleading

    DEFF Research Database (Denmark)

    Hansen, Mikkel; Markman, Ellen M.

    2005-01-01

    Preschoolers' success on the appearance-reality task is a milestone in theory-of-mind development. On the standard task children see a deceptive object, such as a sponge that looks like a rock, and are asked, "What is this really?" and "What does this look like?" Children below 4 1/2 years of age...... fail saying that the object not only is a sponge but also looks like a sponge. We propose that young children's difficulty stems from ambiguity in the meaning of "looks like." This locution can refer to outward appearance ("Peter looks like Paul") but in fact often refers to likely reality ("That looks...... like Jim"). We propose that "looks like" is taken to refer to likely reality unless the reality is already part of the common ground of the conversation. Because this joint knowledge is unclear to young children on the appearance-reality task, they mistakenly think the appearance question is about...

  6. Questions and Answers about BSP

    Directory of Open Access Journals (Sweden)

    D.B. Skillicorn

    1997-01-01

    Full Text Available Bulk Synchronous Parallelism (BSP is a parallel programming model that abstracts from low-level program structures in favour of supersteps. A superstep consists of a set of independent local computations, followed by a global communication phase and a barrier synchronisation. Structuring programs in this way enables their costs to be accurately determined from a few simple architectural parameters, namely the permeability of the communication network to uniformly-random traffic and the time to synchronise. Although permutation routing and barrier synch ronisations are widely regarded as inherently expensive, this is not the case. As a result, the structure imposed by BSP does not reduce performance, while bringing considerable benefits for application building. This paper answers the most common questions we are asked about BSP and justifies its claim to be a major step forward in parallel programming.

    Learner autonomy has been a hot issue discussed by educators in recent years.Because it is believed that the ulti-mate goal of educating is to help students learn autonomously and actively not only in school but also,after graduation,for their whole life.Many people misunderstand the meaning of learner autonomy as learners learn something totally independent from teacher or learn after class.This is not the truth;teacher is indispensible to promote learner autonomy.Therefore,English teacher bears a great respon-sibility of fostering and promoting learner autonomy in the classroom.Questioning is the most frequently used and easiest method in the various teaching methods.

    Bunkers, Sandra S

    2004-07-01

    This column focuses on the philosophical dialogue originated by Socrates. Six questions that Socrates would ask the ancient Greeks are explored in discussing a book written by Phillips entitled Six Questions of Socrates. These questions were: What is virtue? What is moderation? What is justice? What is good? What is courage? What is piety? A human becoming perspective is used as a lens to view the discussion on these questions and the question is posed, "What would it be like to frame discussions on health and quality of life around Socrates' questions?" Parse's teaching-learning processes are presented as a means of creating an environment where dialogue on these questions can occur.

  11. Addressing neurological disorders with neuromodulation.

    Oluigbo, Chima O; Rezai, Ali R

    2011-07-01

    Neurological disorders are becoming increasingly common in developed countries as a result of the aging population. In spite of medications, these disorders can result in progressive loss of function as well as chronic physical, cognitive, and emotional disability that ultimately places enormous emotional and economic on the patient, caretakers, and the society in general. Neuromodulation is emerging as a therapeutic option in these patients. Neuromodulation is a field, which involves implantable devices that allow for the reversible adjustable application of electrical, chemical, or biological agents to the central or peripheral nervous system with the objective of altering its functioning with the objective of achieving a therapeutic or clinically beneficial effect. It is a rapidly evolving field that brings together many different specialties in the fields of medicine, materials science, computer science and technology, biomedical, and neural engineering as well as the surgical or interventional specialties. It has multiple current and emerging indications, and an enormous potential for growth. The main challenges before it are in the need for effective collaboration between engineers, basic scientists, and clinicians to develop innovations that address specific problems resulting in new devices and clinical applications.

    perspectives for future applications. We are most grateful that you agreed with the special format of the symposium which clearly does not follow conven- tional conferences. Allow me to call your special attention once again to two main differences: The presentations are not review papers praising already achieved break-throughs but introductions to a list of open questions and issues for which our understanding is still unsatisfactory. To give such presentations requires courage and scientific integrity. I would like to thank all speakers now already for their willingness to cope with such a difficult task. We have allocated at least 50 minutes for discussion after each presentation not only for discussing the paper as such but, if possible, to find answers to the open questions. If one or several participants in the audience during the discussion think they can contribute to improving our understanding of heterostructures, they are invited to write their ideas up and, if the referees agree, we are more than happy to publish these ideas in the proceedings. We admit that the program is rather demanding. For that reason, we plan to have a break on Thursday afternoon by first going to Denmark and touring the Hamlet castle of Kronborg. We then sail back to Sweden and will be hosted by the Krapperup castle where we will have a candle-light dinner and thereafter a baroque music concert featuring the Concerto Copenhagen. All participants, observers, and accompanying spouses are invited and we hope you will all enjoy the excur- sion. The local organising committee acknowledges with pleasure the financial and all other support received from the Nobel Foundation and the Nobel Institute of Physics as well as the initial initiative taken by the chairman of the Nobel Com- mittee for Physics, Prof. Nordling, who was the first to suggest this Nobel Symposium on "Heterostructures in Semicon- ductors". Special thanks also to the members of the program committee who have been of inestimable

    The Spitzer-South Pole Telescope Deep Field (SSDF) is a wide-area survey using Spitzer's Infrared Array Camera (IRAC) to cover 94 square degrees of extragalactic sky, making it the largest IRAC survey completed to date outside the Milky Way midplane. The SSDF is centered at 23:30,-55:00, in a region that combines observations spanning a broad wavelength range from numerous facilities. These include millimeter imaging from the South Pole Telescope, far-infrared observations from Herschel/SPIRE, X-ray observations from the XMM XXL survey, near-infrared observations from the VISTA Hemisphere Survey, and radio-wavelength imaging from the Australia Telescope Compact Array, in a panchromatic project designed to address major outstanding questions surrounding galaxy clusters and the baryon budget. Here we describe the Spitzer/IRAC observations of the SSDF, including the survey design, observations, processing, source extraction, and publicly available data products. In particular, we present two band-merged catalogs...

The overall mean score of correct answers was 1.56±0.91. Conclusion: Our study showed that young specialists who participated to the survey were not familiarized with simple statistical terms commonly used in presentations.

  15. Address burnout with a caring, nurturing environment.

    Science.gov (United States)

    2014-06-01

    With their hectic schedules and demanding work responsibilities, emergency physicians are particularly vulnerable to symptoms of burnout. One study showed that more than half of emergency providers reported at least one symptom of burnout when they were asked to fill out a survey tool used to measure burnout--more than any other type of provider. It's a concern because physicians experiencing burnout may be less attentive to their patients, and some ultimately choose to leave medicine because they are no longer satisfied with their work. However, there are steps health systems and administrators can take to help physicians who are struggling, and prevent isolated problems from escalating into larger issues. When a national sample of more than 7,200 physicians agreed to take the Maslach Burnout Inventory, a survey tool used to measure burnout, nearly half (45.8%) reported at least one symptom of burnout, and 65% of the emergency providers reported symptoms of burnout. Burnout is not just fatigue. It involves disappointment in a relationship or relationships, and lack of satisfaction or fulfillment with work, according to experts. Symptoms may include moodiness, irritability, sarcasm, and may result in performance issues as well. Further, there may be physical changes such as weight loss or changes in appetite. To prevent or address burnout, experts advise health systems to nurture a caring, collaborative environment, and to make sure that providers have mentors or resources to reach out to if they are experiencing any work-related problems. They also advise administrators to make sure that burnout is a safe topic of conversation.

    2000-01-01

    The objective of the XMM-LSS Survey is to map the large scale structure of the universe, as highlighted by clusters and groups of galaxies, out to a redshift of about 1, over a single 8x8 sq.deg. area. For the first time, this will reveal the topology of the distribution of the deep potential wells and provide statistical measurements at truly cosmological distances. In addition, clusters identified via their X-ray properties will form the basis for the first uniformly-selected, multi-wavelength survey of the evolution of clusters and individual cluster galaxies as a function of redshift. The survey will also address the very important question of the QSO distribution within the cosmic web.

  18. Telephone surveying for drug abuse: methodological issues and an application.

    Science.gov (United States)

    Frank, B

    1985-01-01

    In light of New York State's experience, it is probable that future household drug use surveys will use telephone administration. Drug use questions are not as sensitive as had been thought, and are easily administered by telephone. In addition, the lower costs, the computer-assisted capabilities, and the saving in time are some of the advantages in comparison to face-to-face surveying. In order to address the nontelephone segments of the household population--despite their declining proportion--and to improve response rates, mixed-mode interviewing may have to be considered. Given a better understanding of telephone-associated behavior and the increasing popularity of technological advances, such as the portability and mobility of phones, telephone surveying may become even more attractive in the future.

    Zeder, Melinda A

    2015-03-17

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

    Cancers can now be classified by multidimensional criteria including tumour site, histology, primary - "driver" - molecular alterations, secondary molecular alterations, characteristics of the immune stroma, and genetic profile of the patient. The development of tools for the characterisation of the cancers, as well as novel molecular and immune therapeutics are evolving at an unprecedented pace. In 2012, a list of future challenges was identified at the occasion of the European Organisation for Research and Treatment of Cancer (EORTC) 50(th) anniversary. Three years after, it is interesting to look back at the questions addressed then and to assess the progress of these questions. We propose here a novel set questions which have emerged from the recent publications in this area.

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

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

    Zhang, Xuehu; Ma, Haoming; Li, Qi

    2006-10-01

    We introduce the challenges of address geocoding for Chinese cities and present a potential solution along with a prototype system that deal with these challenges by combining and extending current geocoding solutions developed for United States and Japan. The proposed solution starts by separating city addresses into "standard" addresses which meet a predefined address model and non-standard ones. The standard addresses are stored in a structured relational database in their normalized forms, while a selected portion of the non-standard addresses are stored as aliases to the standard addresses. An in-memory address index is then constructed from the address database and serves as the basis for real-time address matching. Test results were obtained from two trials conducted in the city Beijing. On average 80% matching rate were achieved. Possible improvements to the current design are also discussed.

    Wang, Peng; Wu, Qi; Shen, Chunhua; Dick, Anthony; Hengel, Anton van den

    2017-09-19

    Visual Question Answering (VQA) has attracted much attention in both computer vision and natural language processing communities, not least because it offers insight into the relationships between two important sources of information. Current datasets, and the models built upon them, have focused on questions which are answerable by direct analysis of the question and image alone. The set of such questions that require no external information to answer is interesting, but very limited. It excludes questions which require common sense, or basic factual knowledge to answer, for example. Here we introduce FVQA (Fact-based VQA), a VQA dataset which requires, and supports, much deeper reasoning. FVQA primarily contains questions that require external information to answer. We thus extend a conventional visual question answering dataset, which contains image-question-answer triplets, through additional image-question-answer-supporting fact tuples. Each supporting-fact is represented as a structural triplet, such as .

    2015-08-14

    In March 2012, the SAGE Working Group on Vaccine Hesitancy was convened to define the term "vaccine hesitancy", as well as to map the determinants of vaccine hesitancy and develop tools to measure and address the nature and scale of hesitancy in settings where it is becoming more evident. The definition of vaccine hesitancy and a matrix of determinants guided the development of a survey tool to assess the nature and scale of hesitancy issues. Additionally, vaccine hesitancy questions were piloted in the annual WHO-UNICEF joint reporting form, completed by National Immunization Managers globally. The objective of characterizing the nature and scale of vaccine hesitancy issues is to better inform the development of appropriate strategies and policies to address the concerns expressed, and to sustain confidence in vaccination. The Working Group developed a matrix of the determinants of vaccine hesitancy informed by a systematic review of peer reviewed and grey literature, and by the expertise of the working group. The matrix mapped the key factors influencing the decision to accept, delay or reject some or all vaccines under three categories: contextual, individual and group, and vaccine-specific. These categories framed the menu of survey questions presented in this paper to help diagnose and address vaccine hesitancy.

    The Joint Commission issued a Sentinel Event Alert in August 2011 to address the radiation risks related to diagnostic medical imaging. The University of Nebraska Medical Center (UNMC) and Nebraska Coalition for Patient Safety (NCPS) sent a survey to Nebraska hospital radiology departments in May 2012 to solicit responses regarding radiation safety management practices. Survey results demonstrate that Nebraska hospitals perform well in many radiation safety efforts, but lack in others, as well as the need for additional research to track or compare progress. Nebraska's experience can serve as a model for other states to perform similar radiation safety management research.

  12. Observe-reflect-act: The cycle of reflective practice on questioning in STEM education

    Science.gov (United States)

    Ginley, Erica

    Countless studies have been conducted on questioning techniques in education. However, little research has been focused on the use of reflective practice in relation to teachers' questioning techniques in STEM: Science, Technology, Engineering and Math education. Within this action research study of my own teaching, six lessons were taught, observed, and reflected upon. The main focus was on whether and how reflective practice influences questioning. Through the analysis of video footage, conversation transcriptions, reflective journal entries, pre-service teacher survey, and student work, the importance of different questioning techniques became apparent. They demonstrated that reflective practice has an impact on improving questioning skills and, thus, better engaging students in the learning process.

    Full Text Available With technical advancement, Question Answering has emerged as the main area for the researchers. User is provided with specific answers instead of large number of documents or passages in question answering. Question answering proposes the solution to acquire efficient and exact answers to user question asked in natural language rather than language query. The major goal of this paper is to develop a hybrid algorithm for question answering. For this task different question answering systems for different languages were studied. After deep study, we are able to develop an algorithm that comprises the best features from excellent systems. An algorithm developed by us performs well.

  16. Environment based innovation: policy questions

    Directory of Open Access Journals (Sweden)

    Mario Rui Silva

    2009-12-01

    Full Text Available Natural resources and physical cultural resources, referred to in this paper as “Environmental Resources”, can be important assets for regional competitiveness and innovation. In recent years, these types of assets have been increasingly taken into consideration in the design and implementation of regional development strategies, as a consequence of their potential role as a source of differentiation and of new competitive advantages. However, in contrast to environmental policies, which usually focus on the protection of the environment, innovation policies and their instruments are largely shaped by, and geared towards, knowledge-based innovation.In this paper, we discuss the role played by environmental resources in the context of regional innovation policies. We begin by discussing the relationship between environmental resources and regional development, and by emphasizing some contrasting views with regard to the function of environmental resources in regional development. Then, we address the relationship between regional competitive advantages and innovation strategies. The specific issues and problems that arise whenever the aim is to attain competitive advantages through the valorisation of environmental resources constitute the core of section III. In that section, we highlight the specific characteristics of environmental resources and we discuss the applicability of the “natural resource curse” argument to the dynamics based on the valorisation of environmental resources. The reasons that justify public interventionas well as the difficulties concerning the adequate level of intervention (local / regional / national are also examined. The paper ends with some conclusions and policy implications.

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

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

  20. Computational strategies to address chromatin structure problems

    While the genetic information is contained in double helical DNA, gene expression is a complex multilevel process that involves various functional units, from nucleosomes to fully formed chromatin fibers accompanied by a host of various chromatin binding enzymes. The chromatin fiber is a polymer composed of histone protein complexes upon which DNA wraps, like yarn upon many spools. The nature of chromatin structure has been an open question since the beginning of modern molecular biology. Many experiments have shown that the chromatin fiber is a highly dynamic entity with pronounced structural diversity that includes properties of idealized zig-zag and solenoid models, as well as other motifs. This diversity can produce a high packing ratio and thus inhibit access to a majority of the wound DNA. Despite much research, chromatin’s dynamic structure has not yet been fully described. Long stretches of chromatin fibers exhibit puzzling dynamic behavior that requires interpretation in the light of gene expression patterns in various tissue and organisms. The properties of chromatin fiber can be investigated with experimental techniques, like in vitro biochemistry, in vivo imagining, and high-throughput chromosome capture technology. Those techniques provide useful insights into the fiber’s structure and dynamics, but they are limited in resolution and scope, especially regarding compact fibers and chromosomes in the cellular milieu. Complementary but specialized modeling techniques are needed to handle large floppy polymers such as the chromatin fiber. In this review, we discuss current approaches in the chromatin structure field with an emphasis on modeling, such as molecular dynamics and coarse-grained computational approaches. Combinations of these computational techniques complement experiments and address many relevant biological problems, as we will illustrate with special focus on epigenetic modulation of chromatin structure.

    Electronic surveys are convenient, cost effective, and increasingly popular tools for collecting information. While the online platform allows researchers to recruit and enroll more participants, there is an increased risk of participant dropout in Web-based research. Often, these dropout trends are simply reported, adjusted for, or ignored altogether. To propose a conceptual framework that analyzes respondent attrition and demonstrates the utility of these methods with existing survey data. First, we suggest visualization of attrition trends using bar charts and survival curves. Next, we propose a generalized linear mixed model (GLMM) to detect or confirm significant attrition points. Finally, we suggest applications of existing statistical methods to investigate the effect of internal survey characteristics and patient characteristics on dropout. In order to apply this framework, we conducted a case study; a seventeen-item Informed Decision-Making (IDM) module addressing how and why patients make decisions about cancer screening. Using the framework, we were able to find significant attrition points at Questions 4, 6, 7, and 9, and were also able to identify participant responses and characteristics associated with dropout at these points and overall. When these methods were applied to survey data, significant attrition trends were revealed, both visually and empirically, that can inspire researchers to investigate the factors associated with survey dropout, address whether survey completion is associated with health outcomes, and compare attrition patterns between groups. The framework can be used to extract information beyond simple responses, can be useful during survey development, and can help determine the external validity of survey results.

  8. Molyneux's Question: A Window on Crossmodal Interplay in Blindness

    Directory of Open Access Journals (Sweden)

    Full Text Available In 1688, the Irish scientist William Molyneux sent a letter to the philosopher John Locke in which he asked whether a man who had been born blind and whose experience of the world was based on senses other than vision, would be able to distinguish and name a globe and a cube by sight alone, once he had been enabled to see. This issue immediately raised considerable interest amongst philosophers, who, for centuries, have continued to speculate about how this issue might be resolved. More recently, the possibility of corrective surgery for people born with congenital cataracts, has offered a valuable opportunity to explore this topic experimentally. A discussion of how Molyneux’s question has been addressed over the centuries, allows us to investigate a number of intellectual challenges, involving a variety of fields, ranging from philosophy, psychology and the cognitive sciences, to neuroscience. For instance, Molyenux’s question raises the question of whether sensory experience is specific to each sensory modality, or rather supramodal, and if a transfer of knowledge across modalities can be established. Molyneux’s question is also relevant to the discussion of whether, how and to what extent a concept of space can be developed by blind people. More generally, it concerns the idea of how conceptual knowledge is acquired and processed when vision is lacking. The present paper aims to provide an overview of all the issues raised by Molyenux’s question.

    Questions addressed to something can induce metacognitive function to monitor a person’s thinking process. This study aims to describe the structure of the level of student questions based on thinking level and chemistry understanding level and describe how students use their metacognitive knowledge in asking. This research is a case study in chemistry learning, followed by 87 students. Results of the analysis revealed that the structure of thinking level of student question consists of knowledge question, understanding and application question, and high thinking question; the structure of chemistry understanding levels of student questions are a symbol, macro, macro-micro, macro-process, micro-process, and the macro-micro-process. The level Questioning skill of students to scientific articles more qualified than the level questioning skills of students to the teaching materials. The analysis result of six student interviews, a student question demonstrate the metacognitive processes with categories: (1) low-level metacognitive process, which is compiled based on questions focusing on a particular phrase or change the words; (2) intermediate level metacognitive process, submission of questions requires knowledge and understanding, and (3) high-level metacognitive process, the student questions posed based on identifying the central topic or abstraction essence of scientific articles.

    A passage retrieval strategy for web-based question answering (QA) systems is proposed in our QA system. It firstly analyzes the question based on semantic patterns to obtain its syntactic and semantic information and then form initial queries. The queries are used to retrieve documents from the World Wide Web (WWW) using the Google search engine. The queries are then rewritten to form queries for passage retrieval in order to improve the precision. The relations between keywords in the question are employed in our query rewrite method. The experimental result on the question set of the TREC-2003 passage task shows that our system performs well for factoid questions.

    A language is the tool of human communication. English teaching is really not a way to input or output information-it is not an one-way transmission of information. Students must personally think, speak and write what they are taught. That is the practical features of English teaching. Questioning is one of important methods which embody this feature completely. Teachers apply asking questions to enlighten and stimulate students in order to perfect this vital importance. Students who are in middle schools are asked questions but do not give answers. Except for learners' own quality and degree of difficulty of questions, it is connected with teachers' quality of asking questions.

    Clinical nutrition specialists (CNSs) are often confronted with technological, ethical, and legal questions, that is, what can be done technologically, what should be done ethically, and what must be done legally, which conflict at times. The conflict represents a "troubling trichotomy" as discussed in the lead article of this issue of Nutrition in Clinical Practice (NCP). During Clinical Nutrition Week in 2006, a symposium covering these 3 topics was presented, and later that year, an article covering the same topic was published in NCP In this article, we revisit several legal questions/issues that were raised 10 years ago and discuss current answers and approaches. Some of the answers remain unchanged. Other answers have been modified by additional legislation, court decisions, or regulations. In addition, new questions/issues have arisen. Some of the most common questions regarding nutrition support involve the following: liability, informed consent, medical decisional incapacity vs legal competence, advance directive specificity, surrogate decision making, physician orders for life-sustaining treatment and electronic medical orders for life-sustaining treatment, legal definition of death, patient vs family decision making, the noncompliant patient, and elder abuse obligations. In the current healthcare environment, these questions and issues are best addressed via a transdisciplinary team that focuses on function rather than form. The CNS can play a pivotal role in dealing with these challenges by applying the acronym ACT: being Accountable and Communicating with all stakeholders while actively participating as an integral part of the transdisciplinary Team.

    The epidemiology of heart failure (HF) is changing. This study aimed to describe questions that arise during the routine care of HF patients that are unanswered by the current literature and describe how the type and focus of these questions has changed over time. Investigators from the National Heart, Lung, and Blood Institute-sponsored Heart Failure Apprentice Network collected and categorized questions from 5 academic hospitals over 12 months. A total of 174 unanswered questions were collected and analyzed. Compared with 2004, there were more unanswered questions about "whether" to use therapies and fewer about "how" to use therapies. There were fewer questions about what therapeutic targets, therapy adjustment, and combination therapies. There were more questions about whether or how to stop therapies and how to add therapies back. Newly prominent topics, not observed in 2004, including novel therapeutics, refractory ventricular tachycardia, right heart failure, and nutrition/frailty, accounted for 24% of questions. Compared with 2004, there are fewer unanswered questions about how to use, adjust, and combine therapies. There were more unanswered questions about whether and how to stop therapies. Almost 25% of unanswered questions dealt with topics indicative of more advanced disease which were not observed in 2004. Copyright © 2017 Elsevier Inc. All rights reserved.

  7. Programmatic methods for addressing contaminated volume uncertainties.

    Accurate estimates of the volumes of contaminated soils or sediments are critical to effective program planning and to successfully designing and implementing remedial actions. Unfortunately, data available to support the preremedial design are often sparse and insufficient for accurately estimating contaminated soil volumes, resulting in significant uncertainty associated with these volume estimates. The uncertainty in the soil volume estimates significantly contributes to the uncertainty in the overall project cost estimates, especially since excavation and off-site disposal are the primary cost items in soil remedial action projects. The Army Corps of Engineers Buffalo District's experience has been that historical contaminated soil volume estimates developed under the Formerly Utilized Sites Remedial Action Program (FUSRAP) often underestimated the actual volume of subsurface contaminated soils requiring excavation during the course of a remedial activity. In response, the Buffalo District has adopted a variety of programmatic methods for addressing contaminated volume uncertainties. These include developing final status survey protocols prior to remedial design, explicitly estimating the uncertainty associated with volume estimates, investing in predesign data collection to reduce volume uncertainties, and incorporating dynamic work strategies and real-time analytics in predesign characterization and remediation activities. This paper describes some of these experiences in greater detail, drawing from the knowledge gained at Ashland1, Ashland2, Linde, and Rattlesnake Creek. In the case of Rattlesnake Creek, these approaches provided the Buffalo District with an accurate predesign contaminated volume estimate and resulted in one of the first successful FUSRAP fixed-price remediation contracts for the Buffalo District.

    Comprehensive planning is a visionary planning process that integrates community values and land use policy. The Mayor of Duluth, Minnesota, directed the inclusion of two new values into the City’s comprehensive planning process to direct the community’s future, process: health and fairness. In order to understand the meanings of health and fairness that residents of the city hold, the Community Planning Department included questions in a city-wide survey of planning priorities. As a community organization reviewed the survey results that would inform the new directives, they realized that overburdened communities were underrepresented in the survey responses. To address this deficiency, the community organization asked the City of Duluth if they could conduct a survey of the underrepresented voices to ensure their input was included in the process. The Health in All Policies Coalition contacted the USEPA Office of Research and Development in Duluth, MN at the advice of the Planning Department. The support USEPA provided ensured that the Coalition could make recommendations to the City of Duluth based on systematically collected and analyzed data. This presentation will share the results of the survey. This presentation of the Speak Up Speak Out survey data represents support for local decision-making, technical assistance and data analysis. The data were collected and analyzed through advice and consultation with USEPA Office of Research and Development, an

  10. An analysis of strategies used by chemistry instructors to address student alternate conceptions in chemical equilibrium

    Piquette, Jeff Stephen

    This study explored general-chemistry instructors' awareness of and ability to identify common student alternate conceptions in chemical equilibrium. Instructor strategies directed at remediation of student alternate conceptions were also investigated and compared to successful, literature-based conceptual change methods. Fifty-two general chemistry instructor volunteers from 50 U.S. colleges and universities completed an interactive web-based survey that gathered their responses to open-ended questions, a rating scale, classroom scenarios, and a demographic form. The three scenarios asked respondents to evaluate hypothetical student exam answers, justify their evaluations, and report how they would assist students to better understand ideas about which they held alternate conceptions. Survey respondents who provided responses or remediation strategies that needed further clarification were sampled (n = 6); each amplified their views in an individual, researcher-led semi-structured phone interview. All survey responses and interview transcriptions were independently analyzed by three raters who followed Patton's (1990) guidelines for qualitative data analysis. Data analysis established that all 52 instructors of chemistry were able to report and identify common student alternate conceptions in chemical equilibrium. Those instructor-reported alternate conceptions were congruent with previously identified alternate conceptions (misconceptions) found in published literature, thus providing validation support for the earlier compilations. This study revealed that chemistry instructors employ a variety of strategies in efforts to address and remediate alternate conceptions. However, those strategies rarely include all four conditions outlined by Posner, Strike, Hewson, and Gertzog (1982) needed to stimulate conceptual change in students. Instructors are thus encouraged to become familiar with successful conceptual change strategies, using such methods as appropriate in

    Student often face difficulties with using math in science, and this exploratory project seeks to address the underlying mechanisms that lead to these difficulties. This mixed-methods project includes the creation of two novel assessment surveys, the Mathematical Epistemic Games Survey (MEGS) and the Math Attitude and Expectations Survey (MAX). The MAX, a 30-question Likert-scale survey, focuses on the attitudes towards using mathematics of the students in a reformed introductory physics course for the life sciences (IPLS) which is part of the National Experiment in Undergraduate Education (NEXUS/Physics) developed at the University of Maryland (UMD). Preliminary results from the MAX are discussed with specific attention given to students' attitudes towards math and physics, opinions about interdisciplinarity, and the usefulness of physics in academic settings as well as in professional biological research and modern medicine settings.

    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.

  13. Questions for assessing higher-order cognitive skills: it's not just Bloom's.

    2013-01-01

    We present an exploratory study of biologists' ideas about higher-order cognition questions. We documented the conversations of biologists who were writing and reviewing a set of higher-order cognition questions. Using a qualitative approach, we identified the themes of these conversations. Biologists in our study used Bloom's Taxonomy to logically analyze questions. However, biologists were also concerned with question difficulty, the length of time required for students to address questions, and students' experience with questions. Finally, some biologists demonstrated an assumption that questions should have one correct answer, not multiple reasonable solutions; this assumption undermined their comfort with some higher-order cognition questions. We generated a framework for further research that provides an interpretation of participants' ideas about higher-order questions and a model of the relationships among these ideas. Two hypotheses emerge from this framework. First, we propose that biologists look for ways to measure difficulty when writing higher-order questions. Second, we propose that biologists' assumptions about the role of questions in student learning strongly influence the types of higher-order questions they write.

    Full Text Available Background: Assessments and examinations judge the learning capabilities and test the knowledge and skills that students have acquired during their academic courses. The general paper-pen exams are now slowly being replaced by online testing system. This online assessment is now widely used in medical colleges in western countries and is slowly being introduced in Middle East countries as well. The objectives of the present study were to assess medical student’s perceptions on multiple choice questions (MCQs based E-assessment and to analyze the strength and weakness of the online assessment method. Methods: The study was done on 280 year 2, 3, and 5 students of Oman Medical College (OMC. A 23-item questionnaire that addressed different variables associated with attitudes, perceptions, user comfort factors and type of questions used for assessment about using online examinations was employed. Data were analyzed using the SPSS software. Results: We included 125 (44.6% students from 2nd year, 110 (39.3% from 3rd year, and 45(16.1% students from 5th year. The survey looked upon the four main domains about the use of online exams using multiple choice questions (MCQs: 1. Affective factors, 2. Validity factors, 3. Practicality, and 4. Reliability and Security. Most medical students were comfortable with the online assessment mode. They perceived that the use of MCQs was sufficient to test knowledge during their course. A major theme of concern was technical problems and security issues. Conclusion: Our survey indicated that most students preferred MCQs based E-assessment. However it is evident that the exam system needs to be improved in areas of preparation of well-constructed MCQs, its reliability and validity, practical and technical problems and also regarding the security of the exam system to prepare medical students global competent.

    The main objectives of Earth Science research are many folds: to understand how does this planet operates, can we model her operation and eventually develop the capability to predict such changes. However, the underlying goals of this work are to eventually serve the humanity in providing societal benefits. This requires continuous, and detailed observations from many sources in situ, airborne and space. By and large, the space observations are the way to comprehend the global phenomena across continental boundaries and provide credible boundary conditions for the mesoscale studies. This requires a multiple sensors, look angles and measurements over the same spot in accurately solving many problems that may be related to air quality, multi hazard disasters, public health, hydrology and more. Therefore, there are many ways to address these issues and develop joint implementation, data sharing and operating strategies for the benefit of the world community. This is because for large geographical areas or regions and a diverse population, some sound observations, scientific facts and analytical models must support the decision making. This is crucial for the sustainability of vital resources of the world and at the same time to protect the inhabitants, endangered species and the ecology. Needless to say, there is no single sensor, which can answer all such questions effectively. Due to multi sensor approach, it puts a tremendous burden on any single implementing entity in terms of information, knowledge, budget, technology readiness and computational power. And, more importantly, the health of planet Earth and its ability to sustain life is not governed by a single country, but in reality, is everyone's business on this planet. Therefore, with this notion, it is becoming an impractical problem by any single organization/country to bear this colossal responsibility. So far, each developed country within their means has proceeded along satisfactorily in implementing

    2012-11-01

    Full Text Available Modern societies have become much more complex in recent decades, also in terms of ethnic identities and differences. The question arose whether education systems were capable of addressing the needs of ethnic and other minorities in countries across the globe. After examining a cross-section of education systems (in Australia, Canada, China, Israel, Malaysia, Rwanda, Russia and South Africa with the aid of a set of specially developed criteria, it was concluded that these systems seemed to comply with the criteria in various ways, albeit in different measures and in several configurations. It is recommended that policy makers apply such criteria for enhancing the capability of an education system to address the needs of ethnic minorities and to meet the demands of increased social complexity.

    Visual attention, which assigns weights to image regions according to their relevance to a question, is considered as an indispensable part by most Visual Question Answering models. Although the questions may involve complex relations among multiple regions, few attention models can effectively encode such cross-region relations. In this paper, we demonstrate the importance of encoding such relations by showing the limited effective receptive field of ResNet on two datasets, and propose to mo...

    Full Text Available In 2015, the Millennium Development Goals are due to end. Academics, practitioners and the general public are eager to see which development agenda will take their place and a variety of different organizations are currently elaborating proposals for the next “round” of goals and targets. Instead of investigating possible topics of the upcoming agenda, we focus on methodological questions that – according to our view – will play a major role in the definition and implementation of future development goals. We focus on the elaboration of some key questions that should be addressed in the realm of poverty and inequality measurement, the definition of targets, the ability to consider complexity and evidence-based policy making.

  4. Some additional bioethical questions related to hepatitis B antigen.

    McCullough, L B

    1977-09-01

    Dr. Baruch S. Blumberg has recently raised important questions concerning the bioethics of prevention and cure of hepatitis. This paper extends his inquiry with a view toward examining the full range of the complexity of such issues as the restriction of the use of blood infected with hepatitis B antigen, the screening and possible isolation of health care personnel found to be carriers, and the like. It pointed out that for issues like these, there is not only a conflict between personal liberties and the public interest but also a potential conflict of individual rights, a theme not treated fully by Blumberg. The complex issues that emerge when these two themes are considered together are examined in light of the work of the contemporary American philosopher, John Rawls. His theory permits one to consider these two ethical themes together in analyzing moral problems. In this light, a new strategy is proposed for addressing bioethical questions concerning hepatitis B antigen.

    (Abridged)One of the fundamental challenges for astrophysics in the 21st century is finding a way to untangle the physical processes that govern galaxy formation and evolution. Given the importance and scope of this problem, the multi-wavelength astronomical community has used the past decade to build up a wealth of information over specific extragalactic deep fields to address key questions in galaxy formation and evolution. These fields generally cover at least 10square degrees to facilitate the investigation of the rarest, typically most massive, galaxies and AGN. Furthermore, such areal coverage allows the environments to be fully accounted for, thereby linking the single halo to the two-halo terms in the halo occupation distribution. Surveys at radio wavelengths have begun to lag behind those at other wavelengths, especially in this medium-deep survey tier. However, the survey speed offered by the JVLA means that we can now reach a point where we can begin to obtain commensurate data at radio wavelengths...

    Full Text Available Objective. We aim to investigate methods and use of cervical ripening in women without and with a prior cesarean delivery in The Netherlands. Methods. In 2010, we conducted a postal survey in all Dutch hospitals with a labor ward. One gynecologist per hospital was addressed and was asked to respond on behalf of the staff. The questionnaire contained 31 questions concerning cervical ripening and induction of labor. We compared this survey to a similar Dutch survey conducted in 2006. Results. Response rate was 78% (70/92 hospitals. In women without a prior cesarean and in need of cervical ripening, all hospitals (100% applied prostaglandins (either E1 or E2. In women with a prior cesarean, 21.4% of the hospitals performed an elective cesarean section if delivery was indicated (26.0% in 2006. In case of cervical ripening, 72.7% used mechanical methods (49.1% in 2006, 20.0% used prostaglandins (40.4% in 2006, 3.6% used a combination of prostaglandins and mechanical methods, and 3.6% used membrane-sweeping or oxytocin. Conclusions. In 2010, in The Netherlands, prostaglandins and Foley catheters were the preferred methods for cervical ripening in women without and with a prior cesarean, respectively. Use of mechanical methods in women with a prior cesarean has increased rapidly between 2006 and 2010, corresponding with decreasing use of prostaglandins and elective repeat cesarean sections.

  10. Reasons for discrepancy between incidence and prevalence of epilepsy in lower income countries: Epilepsia's survey results.

    2015-02-01

    From July to August 2014, Epilepsia conducted an online survey seeking opinions that explained the discrepancy between the incidence and prevalence of epilepsy in lower income countries. Data on cumulative incidence suggest a higher rate of active epilepsy than reported in lifetime prevalence surveys. This study reports the findings of that poll addressing the proposal in our Controversy in Epilepsy series that it could be from increased death rates. The survey consisted of a question addressing possible reasons to explain the discrepancy between the incidence and prevalence of epilepsy. Another four questions addressed demographic information. There were 34 responders who completed the survey. Half (50%) of the responders felt that the discrepancy between cumulative incidence and lifetime prevalence was due to lack of uniform definitions and misclassification of patients in study design, 23.5% said the discrepancy was due to a higher mortality from diseases and conditions such as trauma and infections associated with epilepsy, 23.5% indicated that the stigma of epilepsy prevented people from acknowledging their disease in prevalence surveys, and 2.9% felt it was from poor access to qualified medical personal and utilization of medical treatments that increased death rates directly related to epilepsy. Within the limitations of sample size, the results of this survey support that the discrepancy between the incidence and prevalence of epilepsy in lower income regions of the world is due to problems in acquiring the data and stigma rather than higher mortality from diseases associated with epilepsy and repeated seizures.

  11. Addressing the spin question in gravitational-wave searches: Waveform templates for inspiralling compact binaries with nonprecessing spins

    CERN Document Server

    Ajith, P

    2011-01-01

    This paper presents a post-Newtonian (PN) template family of gravitational waveforms from inspiralling compact binaries with non-precessing spins, where the spin effects are described by a single "reduced-spin" parameter. This template family, which reparametrizes all the spin-dependent PN terms in terms of the leading-order (1.5PN) spin-orbit coupling term in an approximate way, has very high overlaps (fitting factor > 0.99) with non-precessing binaries with arbitrary mass ratios and spins. We also show that this template family is "effectual" towards a significant fraction of generic spinning binaries in the comparable-mass regime (m_2/m_1 < 10), providing an attractive and feasible way of searching for gravitational waves (GWs) from spinning low-mass binaries. We also show that the secular (non-oscillatory) spin-dependent effects in the phase evolution (which are taken into account by the non-precessing templates) are more important than the oscillatory effects of precession in the comparable-mass (m_1 ...

  12. Novel Duplicate Address Detection with Hash Function.

    Song, GuangJia; Ji, ZhenZhou

    2016-01-01

    Duplicate address detection (DAD) is an important component of the address resolution protocol (ARP) and the neighbor discovery protocol (NDP). DAD determines whether an IP address is in conflict with other nodes. In traditional DAD, the target address to be detected is broadcast through the network, which provides convenience for malicious nodes to attack. A malicious node can send a spoofing reply to prevent the address configuration of a normal node, and thus, a denial-of-service attack is launched. This study proposes a hash method to hide the target address in DAD, which prevents an attack node from launching destination attacks. If the address of a normal node is identical to the detection address, then its hash value should be the same as the "Hash_64" field in the neighboring solicitation message. Consequently, DAD can be successfully completed. This process is called DAD-h. Simulation results indicate that address configuration using DAD-h has a considerably higher success rate when under attack compared with traditional DAD. Comparative analysis shows that DAD-h does not require third-party devices and considerable computing resources; it also provides a lightweight security resolution.

    This book will be the first covering the subject of IP address management (IPAM). The practice of IPAM includes the application of network management disciplines to IP address space and associated network services, namely DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System). The consequence of inaccurately configuring DHCP is that end users may not be able to obtain IP addresses to access the network. Without proper DNS configuration, usability of the network will greatly suffer as the name-to-address lookup process may fail. Imagine having to navigate to a website or send a

    2003-03-27

    A historical perspective is given of the current paradigm that does not explicitly protect the environment from radiation, but instead, relies on the concept that if dose limits are set to protect humans then the environment is automatically protected as well. We summarize recent international questioning of this paradigm and briefly present three different frameworks for protecting biota that are being considered by the U.S. DOE, the Canadian government and the International Commission on Radiological Protection. We emphasize that an enhanced collaboration is required between what has traditionally been separated disciplines of radiation biology and radiation ecology if we are going to properly address the current environmental radiation problems. We then summarize results generated from an EMSP grant that allowed us to develop a Low Dose Irradiation Facility that specifically addresses effects of low-level, chronic irradiation on multiple levels of biological organization.

    The nature of dark matter, dark energy and large-scale gravity pose some of the most pressing questions in cosmology today. These fundamental questions require highly precise measurements, and a number of wide-field spectroscopic survey instruments are being designed to meet this requirement. A key component in these experiments is the development of a simulation tool to forecast science performance, define requirement flow-downs, optimize implementation, demonstrate feasibility, and prepare for exploitation. We present SPOKES (SPectrOscopic KEn Simulation), an end-to-end simulation facility for spectroscopic cosmological surveys designed to address this challenge. SPOKES is based on an integrated infrastructure, modular function organization, coherent data handling and fast data access. These key features allow reproducibility of pipeline runs, enable ease of use and provide flexibility to update functions within the pipeline. The cyclic nature of the pipeline offers the possibility to make the science outpu...

    2016-12-01

    Central venous catheters (CVCs) account for the largest proportion of thrombotic events in pediatric patients. Questions remain regarding adequate treatment and prevention methods. We surveyed pediatric hematology/oncology specialists, using hypothetical cases to assess management strategies for acute CVC thrombosis and secondary prevention. Survey respondents varied in the use of the thrombophilia evaluation (33.3%, 41/123) and duration of treatment (6 weeks: 54.1%, 66/122). Secondary CVC prophylaxis was utilized by 36.6% (45/123) of respondents and by 24.4% (30/123) but only if there was a documented thrombophilia. This heterogeneity highlights the need for clinical studies to address these important clinical questions.

  17. COMPENDIUM: SURVEYS EVALUATING KNOWLEDGE AND OPINIONS CONCERNING HYDROGEN AND FUEL CELL TECHNOLOGIES

    Truett, Lorena Faith [ORNL; Cooper, Christy [U.S. Department of Energy; Schmoyer, Richard L [ORNL

    2008-10-01

    This compendium updates a 2003 literature review of surveys of knowledge and opinions of hydrogen and fuel cell technologies. Its purpose is to ensure that results of comparable surveys are considered in surveys conducted by the U.S. Department of Energy (DOE). Over twice as many studies related to the DOE survey have been published since 2003 than prior to that date. The fact that there have been significantly more studies implies that there have been further demonstration projects and/or increased interest in hydrogen and fuel cell technologies. The primary findings of these 15 new surveys, all of which were conducted in Europe (E) or North America (NA), to the DOE surveys are as follows: 1.Respondents who are more educated are more accepting of hydrogen technologies (NA). 2.Respondents who are more knowledgeable about hydrogen and/or fuel cells are more accepting of hydrogen technologies (E, NA). 3.When asked about issues of trust, respondents generally expressed distrust of the government or political parties but trusted scientists and environmental protection organizations (E). 4.Technical knowledge about hydrogen and fuel cell technologies is low (E, NA). 5.Respondents may express opinions about a technology even when they are lacking in knowledge of that technology (E). 6.Women and men have different priorities when deciding on an automobile purchase (E). 7.Public acceptance to hydrogen is vulnerable to perceptions of decreased safety (E, NA). 8.Public acceptance to hydrogen is vulnerable to perceptions of increased cost (E, NA). The DOE surveys are similar to surveys that examine technical knowledge of hydrogen and fuel cell technologies, although the technical questions are certainly different. The DOE surveys are also similar to the opinion surveys in that they address many of the same issues, such as safety, sources of energy information, or trust. There are many differences between the surveys reviewed in this compendium and the DOE surveys. The

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

    Science.gov (United States)

    Chouinard, Michael M

    2007-01-01

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

    Full Text Available This research proposes an automatic question generation model for evaluating the understanding of semantic attributes in a sentence. The Semantic Role Labeling and Named Entity Recognition are used as a preprocessing step to convert the input sentence into a semantic pattern. The Artificial Immune System is used to build a classifier that will be able to classify the patterns according to the question type in the training phase. The question types considered here are the set of WH-questions like who, when, where, why, and how. A pattern matching phase is applied for selecting the best matching question pattern for the test sentence. The proposed model is tested against a set of sentences obtained from many sources such as the TREC 2007 dataset for question answering, Wikipedia articles, and English book of grade II preparatory. The experimental results of the proposed model are promising in determining the question type with classification accuracy reaching 95%, and 87% in generating the new question patterns.

    2015-01-01

    Full Text Available Address is a spatial location encoding method of individual geographical area. In China, address planning is relatively backward due to the rapid development of the city, resulting in the presence of large number of non-standard address. The space constrain relationship of standard address model is analyzed in this paper and a new method of standard address extraction based on the tree model is proposed, which regards topological relationship as consistent criteria of space constraints. With this method, standard address can be extracted and errors can be excluded from non-standard address. Results indicate that higher math rate can be obtained with this method.

  12. The six most essential questions in psychiatric diagnosis: a pluralogue. Part 4: general conclusion

    Directory of Open Access Journals (Sweden)

    Phillips James

    2012-12-01

    Full Text Available Abstract In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined.

  13. Alternative Physics Examination Questions: Identification and Explanation of Different Discriminating Powers

    Science.gov (United States)

    Forster, Patricia A.

    2005-12-01

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

  14. Open questions in surface topography measurement: a roadmap

    2015-03-01

    Control of surface topography has always been of vital importance for manufacturing and many other engineering and scientific disciplines. However, despite over one hundred years of quantitative surface topography measurement, there are still many open questions. At the top of the list of questions is ‘Are we getting the right answer?’ This begs the obvious question ‘How would we know?’ There are many other questions relating to applications, the appropriateness of a technique for a given scenario, or the relationship between a particular analysis and the function of the surface. In this first ‘open questions’ article we have gathered together some experts in surface topography measurement and asked them to address timely, unresolved questions about the subject. We hope that their responses will go some way to answer these questions, address areas where further research is required, and look at the future of the subject. The first section ‘Spatial content characterization for precision surfaces’ addresses the need to characterise the spatial content of precision surfaces. Whilst we have been manufacturing optics for centuries, there still isn’t a consensus on how to specify the surface for manufacture. The most common three methods for spatial characterisation are reviewed and compared, and the need for further work on quantifying measurement uncertainties is highlighted. The article is focussed on optical surfaces, but the ideas are more pervasive. Different communities refer to ‘figure, mid-spatial frequencies, and finish’ and ‘form, waviness, and roughness’, but the mathematics are identical. The second section ‘Light scattering methods’ is focussed on light scattering techniques; an important topic with in-line metrology becoming essential in many manufacturing scenarios. The potential of scattering methods has long been recognized; in the ‘smooth surface limit’ functionally significant relationships can be derived from first

  15. Image compression using address-vector quantization

    Science.gov (United States)

    Nasrabadi, Nasser M.; Feng, Yushu

    1990-12-01

    A novel vector quantization scheme, the address-vector quantizer (A-VQ), is proposed which exploits the interblock correlation by encoding a group of blocks together using an address-codebook (AC). The AC is a set of address-codevectors (ACVs), each representing a combination of addresses or indices. Each element of the ACV is an address of an entry in the LBG-codebook, representing a vector-quantized block. The AC consists of an active (addressable) region and an inactive (nonaddressable) region. During encoding the ACVs in the AC are reordered adaptively to bring the most probable ACVs into the active region. When encoding an ACV, the active region is checked, and if such an address combination exists, its index is transmitted to the receiver. Otherwise, the address of each block is transmitted individually. The SNR of the images encoded by the A-VQ method is the same as that of a memoryless vector quantizer, but the bit rate is by a factor of approximately two.

    2017-09-08

    To systematically assess views on contributions and future activities for long-term research in ecology and evolution (LTREE), we conducted and here provide data responses and associated metadata for a survey of ecological and evolutionary scientists. The survey objectives were to: 1) Identify and prioritize research questions that are important to address through long-term, ecological field experiments; and 2) Understand the role that these experiments might play in generating and applying ecological and evolutionary knowledge. The survey was developed adhering to the standards of the American Association for Public Opinion Research. It was administered online using Qualtrics Survey Software. Survey creation was a multi-step process, with questions and format developed and then revised with, for example, input from an external advisory committee comprising senior and junior ecological and evolutionary researchers. The final questionnaire was released to ~100 colleagues to ensure functionality and then fielded two days later (January 7(th) 2015). Two professional societies distributed it to their membership, including the Ecological Society of America, and it was posted to three list serves. The questionnaire was available through February 8(th) 2015 and completed by 1,179 respondents. The distribution approach targeted practicing ecologists and evolutionary biologists in the U.S. Quantitative (both ordinal and categorical) closed-ended questions used a pre-defined set of response categories, facilitating direct comparison across all respondents. Qualitative, open-ended questions, provided respondents the opportunity to develop their own answers. We employed quantitative questions to score views on the extent to which long-term experimental research has contributed to understanding in ecology and evolutionary biology; its role compared to other approaches (e.g. short-term experiments); justifications for and caveats to long-term experiments; and the relative

    The Western Research Institute plan for addressing oil shale plant siting methodology calls for identifying the available resources such as oil shale, water, topography and transportation, and human resources. Restrictions on development are addressed: land ownership, land use, water rights, environment, socioeconomics, culture, health and safety, and other institutional restrictions. Descriptions of the technologies for development of oil shale resources are included. The impacts of oil shale development on the environment, socioeconomic structure, water availability, and other conditions are discussed. Finally, the Western Research Institute plan proposes to integrate these topics to develop a flow chart for oil shale plant siting. Western Research Institute has (1) identified relative topics for shale oil plant siting, (2) surveyed both published and unpublished information, and (3) identified data gaps and research needs. 910 refs., 3 figs., 30 tabs.

  4. True or false: is that the question?

    2015-04-01

    Full Text Available Objectives: Standard tests designed for medical students frequently include objective True/ False (T/F questions, in which there are only two possible answers that can be successfully reached at random. The purpose of this work was to demonstrate that asking for support of the answers diminishes the number of randomly correct ones, so improving the ability of questions to verify learnings. Methods: 8.188 T/F questions whose answers had to be supported; they were applied in 28 written tests of Pathology, at the undergraduate medical program (La Sabana University, Chía, Colombia. Answers were classified as correct or incorrect, and their support, as correct, partially correct and incorrect. In order to analyze the data, the kappa agreement coefficient between T/F questions and T/F questions with support was calculated, as well as per term and per test. Results: Out of 8.188 T/F questions, 6.112 (74.6% were correctly answered as true or false, 3.655 (44.6% had a correct support, and 2.336 (28.5% were not correctly supported, exhibiting a global agreement index of 0.378 and low agreement indexes per term. Conclusion: T/F questions could be accompanied by support of the answers in order to reduce the probability of randomly correct ones, to enhance the development of superior cognitive processes, and communicative essential competences.

  5. Emerging trends in peer review - a survey

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available Classical peer review has been subject to intense criticism for slowing down the publication process, bias against specific categories of paper and author, unreliability, inability to detect errors and fraud, unethical practices, and the lack of recognition for unpaid reviewers. This paper surveys innovative forms of peer review that attempt to address these issues. Based on an initial literature review, we construct a sample of 81 channels of scientific communication covering all forms of review identified by the survey and analyze the review mechanisms used by each channel. We identify two major trends: the rapidly expanding role of pre-print servers (e.g. ArXiv that dispense with traditional peer review altogether and the growth of non-selective review, focusing on papers’ scientific quality rather than their perceived importance and novelty. Other potentially important developments include forms of open review, which remove reviewer anonymity and interactive review, as well as new mechanisms for post-publication review and out-of-channel reader commentary, especially critical commentary targeting high profile papers. One of the strongest findings of the survey is the persistence of major differences between the peer review processes used by different disciplines. None of these differences is likely to disappear in the foreseeable future. The most likely scenario for the coming years is thus continued diversification, in which different review mechanisms serve different author and reader needs. Relatively little is known about the impact of these innovations on the problems they address. These are important questions for future quantitative research.

Any consideration of the problems posed and the lexical or syntactical options available when one sets out to translate forms of address from one language to another must necessarily involve some awareness not only of issues of translation theory, but also of a series of questions usually discussed under the rubrics of sociolinguistics, pragmatics and discourse analysis.

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