    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.

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

  4. Surveying problem solution with theory and objective type questions

    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.

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

    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...

    Full Text Available Background. The purpose of this study was to assess the (previously untested reliability and validity of survey questions commonly used to assess travel mode and travel time. Methods. Sixty-five respondents from a staff survey of travel behaviour conducted in a south-western Sydney hospital agreed to complete a travel diary for a week, wear an accelerometer over the same period, and twice complete an online travel survey an average of 21 days apart. The agreement in travel modes between the self-reported online survey and travel diary was examined with the kappa statistic. Spearman’s correlation coefficient was used to examine agreement of travel time from home to workplace measured between the self-reported online survey and four-day travel diary. Moderate-to-vigorous physical activity (MVPA time of active and nonactive travellers was compared by t-test. Results. There was substantial agreement between travel modes (K=0.62, P<0.0001 and a moderate correlation for travel time (ρ=0.75, P<0.0001 reported in the travel diary and online survey. There was a high level of agreement for travel mode (K=0.82, P<0.0001 and travel time (ρ=0.83, P<0.0001 between the two travel surveys. Accelerometer data indicated that for active travellers, 16% of the journey-to-work time is MVPA, compared with 6% for car drivers. Active travellers were significantly more active across the whole workday. Conclusions. The survey question “How did you travel to work this week? If you used more than one transport mode specify the one you used for the longest (distance portion of your journey” is reliable over 21 days and agrees well with a travel diary.

  7. Comparing Traditional and Crowdsourcing Methods for Pretesting Survey Questions

    Full Text Available Cognitive interviewing is a common method used to evaluate survey questions. This study compares traditional cognitive interviewing methods with crowdsourcing, or “tapping into the collective intelligence of the public to complete a task.” Crowdsourcing may provide researchers with access to a diverse pool of potential participants in a very timely and cost-efficient way. Exploratory work found that crowdsourcing participants, with self-administered data collection, may be a viable alternative, or addition, to traditional pretesting methods. Using three crowdsourcing designs (TryMyUI, Amazon Mechanical Turk, and Facebook, we compared the participant characteristics, costs, and quantity and quality of data with traditional laboratory-based cognitive interviews. Results suggest that crowdsourcing and self-administered protocols may be a viable way to collect survey pretesting information, as participants were able to complete the tasks and provide useful information; however, complex tasks may require the skills of an interviewer to administer unscripted probes.

    Female genital cutting (FGC) has major implications for women's physical, sexual and psychological health, and eliminating the practice is a key target for public health policy-makers. To date one of the main barriers to achieving this has been an inability to infer privately-held views on FGC within communities where it is prevalent. As a sensitive (and often illegal) topic, people are anticipated to hide their true support for the practice when questioned directly. Here we use an indirect questioning method (unmatched count technique) to identify hidden support for FGC in a rural South Central Ethiopian community where the practice is common, but thought to be in decline. Employing a socio-demographic household survey of 1620 Arsi Oromo adults, which incorporated both direct and indirect direct response (unmatched count) techniques we compare directly-stated versus privately-held views in support of FGC, and individual variation in responses by age, gender and education and target female (daughters versus daughters-in-law). Both genders express low support for FGC when questioned directly, while indirect methods reveal substantially higher acceptance (of cutting both daughters and daughters-in-law). Educated adults (those who have attended school) are privately more supportive of the practice than they are prepared to admit openly to an interviewer, indicating that education may heighten secrecy rather than decrease support for FGC. Older individuals hold the strongest views in favour of FGC (particularly educated older males), but they are also more inclined to conceal their support for FGC when questioned directly. As these elders represent the most influential members of society, their hidden support for FGC may constitute a pivotal barrier to eliminating the practice in this community. Our results demonstrate the great potential for indirect questioning methods to advance knowledge and inform policy on culturally-sensitive topics like FGC; providing more

    Full Text Available A Review of: Branscome, B. A. (2013. Management of electronic serials in academic libraries: The results of an online survey. Serials Review, 39(4, 216-226. http://dx.doi.org/10.1016/j.serrev.2013.10.004 Abstract Objective – To examine industry standards for the management of electronic serials and measure the adoption of electronic serials over print. Design – Survey questionnaire. Setting – Email lists aimed at academic librarians working in serials management. Subjects – 195 self-selected subscribers to serials email lists. Methods – The author created a 20 question survey that consisted primarily of closed-ended questions pertaining to the collection demographics, staff, budget, and tools of serials management groups in academic libraries. The survey was conducted via Survey Monkey and examined using the analytical features of the tool. Participants remained anonymous and the survey questions did not ask them to reveal identifiable information about their libraries. Main Results – Collection demographics questions revealed that 78% of surveyed librarians estimated that print-only collections represented 40% or fewer of their serials holdings. The author observed diversity in the factors that influence print to digital transitions in academic libraries. However 71.5% of participants indicated that publisher technology support like IP authentication was required before adopting digital subscriptions. A lack of standardization also marked serials workflows, department responsibilities, and department titles. The author did not find a correlation between serials budget and the enrollment size of the institution. Participants reported that they used tools from popular serials management vendors like Serials Solutions, Innovative Interfaces, EBSCO, and Ex Libris, but most indicated that they used more than one tool for serials management. Participants specified 52 unique serials management products used in their libraries. Conclusion

    Purpose The purpose of this paper is to explore how healthcare first-line managers think about and act regarding workplace survey processes. Design/methodology/approach This interview study was performed at a hospital in south Sweden. First-line healthcare managers ( n=24) volunteered. The analysis was inspired by phenomenography, which aims to describe the ways in which different people experience a phenomenon. The phenomenon was a workplace health promotion (WHP) survey processes. Findings Four main WHP survey process approaches were identified among the managers: as a possibility, as a competition, as a work task among others and as an imposition. For each, three common subcategories emerged; how managers: stated challenges and support from hospital management; described their own work group and collaboration with other managers; and expressed themselves and their situation in their roles as first-line managers. Practical implications Insights into how hospital management can understand their first-line managers' motivation for survey processes and practical suggestions and how managers can work proactively at organizational, group and individual level are presented. Originality/value Usually these studies focus on those who should respond to a survey; not those who should run the survey process. Focusing on managers and not co-workers can lead to more committed and empowered managers and thereby success in survey processes.

  14. 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...

    Standardized surveys are used in many contexts to measure people’s opinions and attitudes. Although it is widely assumed that survey answers represent the ‘true values’ of the concepts measured, a large body of research has shown that seemingly irrelevant question characteristics influence how respondents report their attitudes. The research presented in this dissertation revolved around on one of these characteristics: whether the question is worded positively (This is an interesting book. Y...

    2016-04-27

    Surveys on attitudes towards assisted dying play an important role in informing public debate, policy and legislation. Unfortunately, surveys are often designed with insufficient attention to framing effects; that is, effects on the respondents' stated attitudes caused by question wording and context. The purpose of this study was to demonstrate and measure such framing effects. Survey experiment in which an eight-question survey on attitudes towards assisted dying was distributed to Norwegian citizens through a web-based panel. Two variations of question wording as well as two variations of question order were employed. Respondents were randomized to receive one of four questionnaire versions. Three thousand and fifty responses were received. There were moderate to large question wording and question order effects. A majority of Norwegian citizens favour the legalization of assisted dying for patients with terminal or chronic disease. Stakeholders in the assisted dying debate need to acknowledge potential framing effects, and accordingly should interpret survey results with caution. The same holds for researchers who conduct attitude surveys in the field of bioethics.

  1. Comparing expressed and revealed preferences for risk reduction: different hazards and question frames

    International Nuclear Information System (INIS)

    McDaniels, T.L.

    1988-01-01

    Studies often note the wide differences that exist in costs per death avoided across US federal programs and regulatory contexts. This paper explores two new, related explanations for these differences. First, it argues that the patterns of revealed preferences (public allocations) may be related to public values, which are measured here through subjects' expressed preference responses to a contingent valuation survey regarding risk reduction. Subjects' expressed values are compared to actual (and proposed) costs of safety regulations for a similar set of hazards. The authors discover strong congruence in the ranking of expressed values and actual values. Second, the paper presents the results of a subsequent survey that investigates why the patterns observed in the first survey might occur. It suggests that one reason for the observed similarities between revealed and expressed preferences may be in how choices are framed. The paper hypothesizes that both subjects and decision makers may frame valuation decisions in the same way: as percentage changes from the reference point provided by the base rate of deaths for that hazard

    2018-01-01

    Text message programs for sexual health are becoming increasingly popular as practitioners aim to meet youth on media they use frequently. Two-way mobile health (mHealth) interventions allow for feedback solicitation from participants. This study explores the use of a text message survey to assess demographics and program feedback from users of an adolescent sexual health text message question-and-answer service. Development and feasibility of the short-message service survey are discussed. The text message survey achieved a 43.9% response rate, which is comparable to response rates of surveys conducted via other methods. When compared to respondents who used the service and completed an online in-school questionnaire, text survey respondents were more likely to be female and older. They also reported higher service satisfaction. Results have implications for text message service providers and researchers. This article examines a community application of a new intervention strategy and research methodology.

  7. 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.

    Although the item count technique is useful in surveys with sensitive questions, privacy of those respondents who possess the sensitive characteristic of interest may not be well protected due to a defect in its original design. In this article, we propose two new survey designs (namely the Poisson item count technique and negative binomial item count technique) which replace several independent Bernoulli random variables required by the original item count technique with a single Poisson or negative binomial random variable, respectively. The proposed models not only provide closed form variance estimate and confidence interval within [0, 1] for the sensitive proportion, but also simplify the survey design of the original item count technique. Most importantly, the new designs do not leak respondents' privacy. Empirical results show that the proposed techniques perform satisfactorily in the sense that it yields accurate parameter estimate and confidence interval.

    The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel surveys reveal (1) that there was rapid galaxy evolution in the very recent past and (2) that galaxies lie on a single Galaxy Sequence (GS) rather than a star-forming 'main sequence' and a separate region of 'passive' or 'red-and-dead' galaxies. The form of the GS is now clearer because far-infrared surveys such as the Herschel ATLAS pick up a population of optically red star-forming galaxies that would have been classified as passive using most optical criteria. The space-density of this population is at least as high as the traditional star-forming population. By stacking spectra of H-ATLAS galaxies over the redshift range 0.001 high stellar masses, high star-formation rates but, even several billion years in the past, old stellar populations - they are thus likely to be relatively recent ancestors of early-type galaxies in the Universe today. The form of the GS is inconsistent with rapid quenching models and neither the analytic bathtub model nor the hydrodynamical EAGLE simulation can reproduce the rapid cosmic evolution. We propose a new gentler model of galaxy evolution that can explain the new Herschel results and other key properties of the galaxy population.

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

    Science.gov (United States)

    2012-01-01

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

    2009-10-01

    Music-induced hearing loss (MIHL), an unconsciously self-inflicted public health concern, could evolve into an epidemic because of the appeal of loud music. After media attention about a previous hearing-loss survey with Music Television (MTV.com), we hypothesized that a repeat survey could compare awareness and behavior trends. We incorporated the 2002 survey into the new 73-question instrument presented to random visitors on the MTV.com website in 2007. A P music exposure. Health care providers were the least likely source of MIHL awareness despite the respondents favoring provider education for hearing protection behavior modification. Most respondents still could not recall learning about prevention of potential hearing loss, although the media has become the most informative source. Most respondents indicated that they would adopt protective ear behavior if made aware of hearing loss risk, especially if informed by health care professionals, revealing an educational opportunity.

    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.

    Population surveys are frequently used to assess prevalence, correlates and health benefits of physical activity. However, nonsampling errors, such as question order effects, in surveys may lead to imprecision in self reported physical activity. This study examined the impact of modified question order in a commonly used physical activity questionnaire on the prevalence of sufficient physical activity. Data were obtained from a telephone survey of adults living in Queensland, Australia. A total of 1243 adults participated in the computer-assisted telephone interview (CATI) survey conducted in July 2008 which included the Active Australia Questionnaire (AAQ) presented in traditional or modified order. Binary logistic regression analyses was used to examine relationships between question order and physical activity outcomes. Significant relationships were found between question order and sufficient activity, recreational walking, moderate activity, vigorous activity, and total activity. Respondents who received the AAQ in modified order were more likely to be categorized as sufficiently active (OR = 1.28, 95% CI 1.01-1.60). This study highlights the importance of question order on estimates of self reported physical activity. This study has shown that changes in question order can lead to an increase in the proportion of participants classified as sufficiently active.

    In France, attempts to define common ground during spine surgery meetings have revealed significant variability in clinical practices across different schools of surgery and the two specialities involved in spine surgery, namely, neurosurgery and orthopaedic surgery. To objectively characterise this variability by performing a survey based on a fictitious spine trauma case. Our working hypothesis was that significant variability existed in trauma practices and that this variability was related to a lack of strong scientific evidence in spine trauma care. We performed a cross-sectional survey based on a clinical vignette describing a 31-year-old male with an L1 burst fracture and neurologic symptoms (numbness). Surgeons received the vignette and a 14-item questionnaire on the management of this patient. For each question, surgeons had to choose among five possible answers. Differences in answers across surgeons were assessed using the Index of Qualitative Variability (IQV), in which 0 indicates no variability and 1 maximal variability. Surgeons also received a questionnaire about their demographics and surgical experience. Of 405 invited spine surgeons, 200 responded to the survey. Five questions had an IQV greater than 0.9, seven an IQV between 0.5 and 0.9, and two an IQV lower than 0.5. Variability was greatest about the need for MRI (IQV=0.93), degree of urgency (IQV=0.93), need for fusion (IQV=0.92), need for post-operative bracing (IQV=0.91), and routine removal of instrumentation (IQV=0.94). Variability was lowest for questions about the need for surgery (IQV=0.42) and use of the posterior approach (IQV=0.36). Answers were influenced by surgeon specialty, age, experience level, and type of centre. Clinical practice regarding spine trauma varies widely in France. Little published evidence is available on which to base recommendations that would diminish this variability. Copyright © 2015. Published by Elsevier Masson SAS.

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

    Cerro Negro, near León, Nicaragua is a young, relatively small basaltic cinder cone volcano that has been unusually active during its short lifespan. Multiple explosive eruptions have deposited significant amounts of ash on León and the surrounding rural communities. While a number of studies investigate the geochemistry and stress regime of the volcano, subsurface structures have only been studied by diffuse soil gas surveys. These studies have raised several questions as to the proper classification of Cerro Negro and its relation to neighboring volcanic features. To address these questions, we collected 119 gravity measurements around Cerro Negro volcano in an attempt to delineate deep structures at the volcano. The resulting complete Bouguer anomaly map revealed local positive gravity anomalies (wavelength 0.5 to 2 km, magnitude +4 mGal) and regional positive (10 km wavelength, magnitudes +10 and +8 mGal) and negative (12 and 6 km wavelength, magnitudes -18 and -13 mGal) Bouguer anomalies. Further analysis of these gravity data through inversion has revealed both local and regional density anomalies that we interpret as intrusive complexes at Cerro Negro and in the Nicaraguan Volcanic Arc. The local density anomalies at Cerro Negro have a density of 2700 kg m-3 (basalt) and are located between -250 and -2000 m above sea level. The distribution of recovered density anomalies suggests that eruptions at Cerro Negro may be tapping an interconnected magma plumbing system beneath El Hoyo, Cerro La Mula, and Cerro Negro, and more than seven other proximal volcanic features, implying that Cerro Negro should be considered the newest cone of a Cerro Negro-El Hoyo volcanic complex.

    2016-12-01

    Background: Subjects regarding ethical questions in dental medicine are only slightly touched in the study of dental medicine or in the working regulations of the dentists' association. However, dentists are confronted with these matters in everyday working life. The empirical study at hand collects current data regarding the ethical knowledge about dental medicine in the practical experience of dentists in Saxony, Saxony-Anhalt, and Thuringia. Methods: The tool used in the survey was a structured questionnaire. Out of 600 randomly chosen and contacted dentists from Saxony, Saxony-Anhalt, and Thuringia, 290 replied (response rate: 48.3%). The anonymised assessment took place between June and November 2013. Results: Dentists frequently encounter ethical questions regarding dental matters. The dentists interviewed in the study are in favour of a participative relationship between patient and dentist. Simultaneously, the patient's health is predominantly seen as the good of higher value than his or her self-determination. The dentists show competent knowledge of ethical dental subjects, although increased uncertainties could be observed in more complex situations, e. g. considering contact with patients who are HIV-positive. Conclusions: Questions dealing with dental ethical questions do play a major role in the daily professional life of dentists. In order to further support and strengthen dentists in their individual dental ethical competence, we see a need for advanced training and further education regarding questions and problems in the area of ethics in dental medicine. Also, these topics should become a component in the curriculum of the study of dental medicine. © Georg Thieme Verlag KG Stuttgart · New York.

    Assessing consumer perceptions and willingness to pay for genetically modified (GM) foods has been one of the most active areas of empirical research in agricultural economics. Researchers over the past 15 years have delivered well over 100 estimates of consumers' willingness to pay for GM foods using surveys and experimental methods. In this review, we explore a number of unresolved issues related to three questions that are critical when considering the sum of the individual contributions that constitute the evidence on consumer preferences for GM foods.

    Understanding attitudes about intimate partner violence (IPV) in cultural context is important for developing interventions to reduce it or mitigate its effects. This article presents qualitative findings from research conducted in rural Bangladesh to understand men's and women's responses to attitudinal questions about IPV. Both men and women often responded as if the questions were about their personal behavior. A few women said that their opinion did not matter. Women's responses were more sensitive than men's to contextual nuances in the questions, and men more often than women described their own attitudes as consistent with community norms.

    Runge, Catherine E.; Waller, Michael; MacKenzie, Alison; McGuire, Annabel C. L.

    2014-01-01

    Introduction There are few studies on the experiences of spouses of military members, with most focused on adverse impacts of deployment. Responses to an open-ended question in a survey of spouses' health and wellbeing enabled access to perceptions and insights on a broad range of topics. The objective of this investigation was to examine how respondents used the open-ended question and what they discussed, in aim of informing support service agencies and spouses of military members. Methods Thematic analysis was conducted on responses to the open-ended question. Descriptive analysis was performed on the demographics, military member characteristics and self-reported health of respondents and non-respondents to the open-ended question. Findings Over a quarter (28.5%) of the 1,332 survey participants answered the open-ended question, with respondents having a significantly higher level of education than non–respondents. Respondents expressed negative and positive experiences and insights on military life, provided personal information, commented on the survey, and qualified their responses to closed-ended questions. Topics included ‘inadequate support’, ‘deployment impacts’, ‘suggestions for supporting agencies’, ‘appraisal of experiences’ and ‘coping strategies’. Conclusions This investigation uncovered issues of importance to spouses of military members that were not included or identified in a quantitative study. The findings provide a platform from which to explore these issues further, particularly the impact of military life on the non-serving spouse's career. The findings also provide support agencies with evidence to strengthen their services and they give spouses an opportunity to reflect on their own and others' feelings and evaluations of military life.

    Neuroinfectious diseases in livestock represent a severe threat to animal health, but their prevalence is not well documented and the etiology of disease often remains unidentified. The aims of this study were to generate baseline data on the prevalence of neuroinfectious diseases in cattle in Switzerland by neuropathological survey, and to identify disease-associated pathogens. The survey was performed over a 1-year period using a representative number of brainstem samples (n=1816) from fallen cattle. In total, 4% (n=73) of the animals had significant lesions, the most frequent types of which were indicative of viral (n=27) and bacterial (n=31) etiologies. Follow-up diagnostics by immunohistochemistry, PCR protocols and next-generation sequencing identified infection with Listeria monocytogenes (n=6), ovine herpesvirus 2 (n=7), bovine astrovirus CH13 (n=2), bovine herpesvirus 6 (n=6), bovine retrovirus CH15 (n=2), posavirus 1 (n=2), and porcine astroviruses (n=2). A retrospective questionnaire-based investigation indicated that animals' owners observed clinical signs of neurological disease in about one-third of cases with lesions, which was estimated to correspond to approximately 85 cases per year in the adult fallen cattle population in Switzerland. This estimate stands in sharp contrast to the number of cases reported to the authorities and reveals a gap in disease surveillance. Systematic neuropathological examination and follow-up molecular testing of neurologically diseased cattle could significantly enhance the efficiency of disease detection for the purposes of estimating the prevalence of endemic diseases, identifying new or re-emerging pathogens, and providing "early warnings" of disease outbreaks.

  17. Bees for development: Brazilian survey reveals how to optimize stingless beekeeping.

    Directory of Open Access Journals (Sweden)

    Rodolfo Jaffé

    Full Text Available Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains an essentially informal activity, technical knowledge is scarce, and management practices lack standardization. Here we profited from the large diversity of stingless beekeepers found in Brazil to assess the impact of particular management practices on productivity and economic revenues from the commercialization of stingless bee products. Our study represents the first large-scale effort aiming at optimizing stingless beekeeping for honey/colony production based on quantitative data. Survey data from 251 beekeepers scattered across 20 Brazilian States revealed the influence of specific management practices and other confounding factors over productivity and income indicators. Specifically, our results highlight the importance of teaching beekeepers how to inspect and feed their colonies, how to multiply them and keep track of genetic lineages, how to harvest and preserve the honey, how to use vinegar traps to control infestation by parasitic flies, and how to add value by labeling honey containers. Furthermore, beekeeping experience and the network of known beekeepers were found to be key factors influencing productivity and income. Our work provides clear guidelines to optimize stingless beekeeping and help transform the activity into a powerful tool for sustainable development.

  20. ROV advanced magnetic survey for revealing archaeological targets and estimating medium magnetization

    Science.gov (United States)

    Eppelbaum, Lev

    2013-04-01

    Magnetic survey is one of most applied geophysical method for searching and localization of any objects with contrast magnetic properties (for instance, in Israel detailed magneric survey has been succesfully applied at more than 60 archaeological sites (Eppelbaum, 2010, 2011; Eppelbaum et al., 2011, 2010)). However, land magnetic survey at comparatively large archaeological sites (with observation grids 0.5 x 0.5 or 1 x 1 m) may occupy 5-10 days. At the same time the new Remote Operation Vehicle (ROV) generation - small and maneuvering vehicles - can fly at levels of few (and even one) meters over the earth's surface (flowing the relief forms or straight). Such ROV with precise magnetic field measurements (with a frequency of 20-25 observations per second) may be performed during 10-30 minutes, moreover at different levels over the earth's surface. Such geophysical investigations should have an extremely low exploitation cost. Finally, measurements of geophysical fields at different observation levels could provide new unique geophysical-archaeological information (Eppelbaum, 2005; Eppelbaum and Mishne, 2011). The developed interpretation methodology for magnetic anomalies advanced analysis (Khesin et al., 1996; Eppelbaum et al., 2001; Eppelbaum et al., 2011) may be successfully applied for ROV magnetic survey for delineation of archaeological objects and estimation averaged magnetization of geological medium. This methodology includes: (1) non-conventional procedure for elimination of secondary effect of magnetic temporary variations, (2) calculation of rugged relief influence by the use of a correlation method, (3) estimation of medium magnetization, (4) application of various informational and wavelet algorithms for revealing low anomalous effects against the strong noise background, (5) advanced procedures for magnetic anomalies quantitative analysis (they are applicable in conditions of rugged relief, inclined magnetization, and an unknown level of the total

    This study examines the effect of question context created by order in questionnaires on three subjective well-being measures: life satisfaction, self-rated health, and subjective life expectancy. We conducted two Web survey experiments. The first experiment (n = 648) altered the order of life satisfaction and self-rated health: (1) life satisfaction asked immediately after self-rated health; (2) self-rated health immediately after life satisfaction; and (3) two items placed apart. We examined their correlation coefficient by experimental condition and further examined its interaction with objective health. The second experiment (n = 479) asked life expectancy before and after parental mortality questions. Responses to life expectancy were compared by order using ANOVA, and we examined interaction with parental mortality status using ANCOVA. Additionally, response time and probes were examined. Correlation coefficients between self-rated health and life satisfaction differed significantly by order: 0.313 (life satisfaction first), 0.508 (apart), and 0.643 (self-rated health first). Differences were larger among respondents with chronic conditions. Response times were the shortest when self-rated health was asked first. When life expectancy asked after parental mortality questions, respondents reported considering parents more for answering life expectancy; and respondents with deceased parents reported significantly lower expectancy, but not those whose parents were alive. Question context effects exist. Findings suggest placing life satisfaction and self-rated health apart to avoid artificial attenuation or inflation in their association. Asking about parental mortality prior to life expectancy appears advantageous as this leads respondents to consider parental longevity more, an important factor for true longevity.

    2016-01-01

    Purpose 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. Material and Methods 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. Results 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. Discussion 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.

  6. Synoptic sky surveys and the diffuse supernova neutrino background: Removing astrophysical uncertainties and revealing invisible supernovae

    Lien, Amy; Fields, Brian D.; Beacom, John F.

    2010-01-01

    The cumulative (anti)neutrino production from all core-collapse supernovae within our cosmic horizon gives rise to the diffuse supernova neutrino background (DSNB), which is on the verge of detectability. The observed flux depends on supernova physics, but also on the cosmic history of supernova explosions; currently, the cosmic supernova rate introduces a substantial (±40%) uncertainty, largely through its absolute normalization. However, a new class of wide-field, repeated-scan (synoptic) optical sky surveys is coming online, and will map the sky in the time domain with unprecedented depth, completeness, and dynamic range. We show that these surveys will obtain the cosmic supernova rate by direct counting, in an unbiased way and with high statistics, and thus will allow for precise predictions of the DSNB. Upcoming sky surveys will substantially reduce the uncertainties in the DSNB source history to an anticipated ±5% that is dominated by systematics, so that the observed high-energy flux thus will test supernova neutrino physics. The portion of the universe (z < or approx. 1) accessible to upcoming sky surveys includes the progenitors of a large fraction (≅87%) of the expected 10-26 MeV DSNB event rate. We show that precision determination of the (optically detected) cosmic supernova history will also make the DSNB into a strong probe of an extra flux of neutrinos from optically invisible supernovae, which may be unseen either due to unexpected large dust obscuration in host galaxies, or because some core-collapse events proceed directly to black hole formation and fail to give an optical outburst.

    African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite global attention to the plight of elephants, their population sizes and trends are uncertain or unknown over much of Africa. To conserve this iconic species, conservationists need timely, accurate data on elephant populations. Here, we report the results of the Great Elephant Census (GEC), the first continent-wide, standardized survey of African savannah elephants. We also provide the first quantitative model of elephant population trends across Africa. We estimated a population of 352,271 savannah elephants on study sites in 18 countries, representing approximately 93% of all savannah elephants in those countries. Elephant populations in survey areas with historical data decreased by an estimated 144,000 from 2007 to 2014, and populations are currently shrinking by 8% per year continent-wide, primarily due to poaching. Though 84% of elephants occurred in protected areas, many protected areas had carcass ratios that indicated high levels of elephant mortality. Results of the GEC show the necessity of action to end the African elephants' downward trajectory by preventing poaching and protecting habitat.

    The Monday, July 17, 2006 Central Javan 7.7 earthquake triggered a substantial tsunami that killed 600 people along a 200km stretch of coastline. The earthquake was not reported felt along the coastline. While there was a warning issued by the PTWC, it did not trigger an evacuation warning (Synolakis, 2006). The Indian Ocean Tsunami Warning System announced by UNESCO as operational in a press release two weeks before the event did not function as promised. There were no seismic recordings transmitted to the PTWC, and two German tsunameter buoys had broken off their moorings and were not operational. Lifeguards along a tourist beach reported that while the observed the harbinger shoreline recession, they attributed to exteme storm waves that were pounding the beaches that day. Had the tsunami struck on the preceding Sunday, instead of Monday, the death toll would had been far higher. The International Tsunami Survey Team (ITST) surveyed the coastline measuring runup, inundation, flow depths and sediment deposition, with standard methods (Synolakis and Okal, 2004). Runup values ranged up to 21m with several readings over 10m, while sand sheets up to 15cm were deposited. The parent earthquake was similar, albeit of smaller magnitude, to the 1994 East Javan tsunami, which struck about 200km east (Synolakis, et al, 1995) and reached a maximum of 11m runup height only at one location on steep cliffs. The unusual distribution of runup heights, and the pronounced extreme values near Nusa Kambangan, suggest a local coseismic landslide may have triggered an additional tsunami (Okal and Synolakis, 2005). The ITST observed that many coastal villages were completely abandoned after the tsunami, even in locales where there were no casualties. Whether residents will return is uncertain, but it is clear that an education campaign in tsunami hazard mitigation is urgently needed. In the aftermath of the tsunami, the Government of Indonesia enforced urgent emergency preparedness

    Variations in the stellar initial mass function (IMF) have been invoked to explain the spectroscopic and dynamical properties of early-type galaxies (ETGs). However, no observations have yet been able to disentangle the physical driver. We analyze here a sample of 24 ETGs drawn from the CALIFA survey, deriving in a homogeneous way their stellar population and kinematic properties. We find that the local IMF is tightly related to the local metallicity, becoming more bottom-heavy toward metal-rich populations. Our result, combined with the galaxy mass–metallicity relation, naturally explains previous claims of a galaxy mass–IMF relation, derived from non-IFU spectra. If we assume that—within the star formation environment of ETGs—metallicity is the main driver of IMF variations, a significant revision of the interpretation of galaxy evolution observables is necessary

  13. Baseline reef health surveys at Bangka Island (North Sulawesi, Indonesia reveal new threats

    Full Text Available Worldwide coral reef decline appears to be accompanied by an increase in the spread of hard coral diseases. However, whether this is the result of increased direct and indirect human disturbances and/or an increase in natural stresses remains poorly understood. The provision of baseline surveys for monitoring coral health status lays the foundations to assess the effects of any such anthropogenic and/or natural effects on reefs. Therefore, the objectives of this present study were to provide a coral health baseline in a poorly studied area, and to investigate possible correlations between coral health and the level of anthropogenic and natural disturbances. During the survey period, we recorded 20 different types of coral diseases and other compromised health statuses. The most abundant were cases of coral bleaching, followed by skeletal deformations caused by pyrgomatid barnacles, damage caused by fish bites, general pigmentation response and galls caused by cryptochirid crabs. Instances of colonies affected by skeletal eroding bands, and sedimentation damage increased in correlation to the level of bio-chemical disturbance and/or proximity to villages. Moreover, galls caused by cryptochirid crabs appeared more abundant at sites affected by blast fishing and close to a newly opened metal mine. Interestingly, in the investigated area the percentage of corals showing signs of ‘common’ diseases such as black band disease, brown band disease, white syndrome and skeletal eroding band disease were relatively low. Nevertheless, the relatively high occurrence of less common signs of compromised coral-related reef health, including the aggressive overgrowth by sponges, deserves further investigation. Although diseases appear relatively low at the current time, this area may be at the tipping point and an increase in activities such as mining may irredeemably compromise reef health.

    EML4-ALK gene fusion (inv2(p21p23)) of non-small cell lung cancer (NSCLC) predisposes to tyrosine kinase inhibitor treatment. One of the gold standard diagnostics is the dual color (DC) break-apart (BA) FISH technique, however, the unusual closeness of the involved genes has been suggested to raise likelihood of random co-localization (RCL) of signals. Although this is suspected to decrease sensitivity (often to as low as 40-70%), the exact level and effect of RCL has not been revealed thus far. Signal distances were analyzed to the 0.1 µm precision in more than 25,000 nuclei, via automated high content-image cytometry. Negative and positive controls were created using conventional DC BA-, and inv2(p21p23) mimicking probe-sets, respectively. Average distance between red and green signals was 9.72 pixels (px) (±5.14px) and 3.28px (±2.44px), in positives and negatives, respectively; overlap in distribution being 41%. Specificity and sensitivity of correctly determining ALK status was 97% and 29%, respectively. When investigating inv2(p21p23) with DC BA FISH, specificity is high, but seven out of ten aberrant nuclei are inevitably falsely classified as negative, due to the extreme level of RCL. Together with genetic heterogeneity and dilution effect of non-tumor cells in NSCLC, this immense analytical false negativity is the primary cause behind the often described low diagnostic sensitivity. These results convincingly suggest that if FISH is to remain a gold standard for detecting the therapy relevant inv(2), either a modified evaluation protocol, or a more reliable probe-design should be considered than the current DC BA one. © 2018 International Society for Advancement of Cytometry. © 2018 International Society for Advancement of Cytometry.

    Control efforts towards malaria due to Plasmodium falciparum significantly decreased the incidence of the disease in many endemic countries including Senegal. Surprisingly, in Kedougou (southeastern Senegal) P. falciparum malaria remains highly prevalent and the relative contribution of other Plasmodium species to the global malaria burden is very poorly documented, partly due to the low sensitivity of routine diagnostic tools. Molecular methods offer better estimate of circulating Plasmodium species in a given area. A molecular survey was carried out to document circulating malaria parasites in Kedougou region. A total of 263 long-term stored sera obtained from patients presenting with acute febrile illness in Kedougou between July 2009 and July 2013 were used for malaria parasite determination. Sera were withdrawn from a collection established as part of a surveillance programme of arboviruses infections in the region. Plasmodium species were characterized by a nested PCR-based approach targeting the 18S small sub-unit ribosomal RNA genes of Plasmodium spp. Of the 263 sera screened in this study, Plasmodium genomic DNA was amplifiable by nested PCR from 62.35% (164/263) of samples. P. falciparum accounted for the majority of infections either as single in 85.97% (141/164) of Plasmodium-positive samples or mixed with Plasmodium ovale (11.58%, 19/164) or Plasmodium vivax (1.21%, 2/164). All 19 (11.58%) P. ovale-infected patients were mixed with P. falciparum, while no Plasmodium malariae was detected in this survey. Four patients (2.43%) were found to be infected by P. vivax, two of whom were mixed with P. falciparum. P. vivax infections originated from Bandafassi and Ninefesha villages and concerned patients aged 4, 9, 10, and 15 years old, respectively. DNA sequences alignment and phylogenetic analysis demonstrated that sequences from Kedougou corresponded to P. vivax, therefore confirming the presence of P. vivax infections in Senegal. The results confirm the

    Solid insight into the physics of the inner Milky Way is key to understanding our Galaxy’s evolution, but extreme dust obscuration has historically hindered efforts to map the area along the Galactic mid-plane. New comprehensive near-infrared time-series photometry from the VVV Survey has revealed 35 classical Cepheids, tracing a previously unobserved component of the inner Galaxy, namely a ubiquitous inner thin disk of young stars along the Galactic mid-plane, traversing across the bulge. The discovered period (age) spread of these classical Cepheids implies a continuous supply of newly formed stars in the central region of the Galaxy over the last 100 million years.

  17. Systematic survey reveals general applicability of "guilt-by-association" within gene coexpression networks

    Full Text Available Abstract Background Biological processes are carried out by coordinated modules of interacting molecules. As clustering methods demonstrate that genes with similar expression display increased likelihood of being associated with a common functional module, networks of coexpressed genes provide one framework for assigning gene function. This has informed the guilt-by-association (GBA heuristic, widely invoked in functional genomics. Yet although the idea of GBA is accepted, the breadth of GBA applicability is uncertain. Results We developed methods to systematically explore the breadth of GBA across a large and varied corpus of expression data to answer the following question: To what extent is the GBA heuristic broadly applicable to the transcriptome and conversely how broadly is GBA captured by a priori knowledge represented in the Gene Ontology (GO? Our study provides an investigation of the functional organization of five coexpression networks using data from three mammalian organisms. Our method calculates a probabilistic score between each gene and each Gene Ontology category that reflects coexpression enrichment of a GO module. For each GO category we use Receiver Operating Curves to assess whether these probabilistic scores reflect GBA. This methodology applied to five different coexpression networks demonstrates that the signature of guilt-by-association is ubiquitous and reproducible and that the GBA heuristic is broadly applicable across the population of nine hundred Gene Ontology categories. We also demonstrate the existence of highly reproducible patterns of coexpression between some pairs of GO categories. Conclusion We conclude that GBA has universal value and that transcriptional control may be more modular than previously realized. Our analyses also suggest that methodologies combining coexpression measurements across multiple genes in a biologically-defined module can aid in characterizing gene function or in characterizing

    An unbiased survey has been made of the stable, most abundant multi-protein complexes in Desulfovibrio vulgaris Hildenborough (DvH) that are larger than Mr {approx} 400 k. The quaternary structures for 8 of the 16 complexes purified during this work were determined by single-particle reconstruction of negatively stained specimens, a success rate {approx}10 times greater than that of previous 'proteomic' screens. In addition, the subunit compositions and stoichiometries of the remaining complexes were determined by biochemical methods. Our data show that the structures of only two of these large complexes, out of the 13 in this set that have recognizable functions, can be modeled with confidence based on the structures of known homologs. These results indicate that there is significantly greater variability in the way that homologous prokaryotic macromolecular complexes are assembled than has generally been appreciated. As a consequence, we suggest that relying solely on previously determined quaternary structures for homologous proteins may not be sufficient to properly understand their role in another cell of interest.

  19. Survey of tyrosine kinase signaling reveals ROS kinase fusions in human cholangiocarcinoma.

    Directory of Open Access Journals (Sweden)

    Ting-Lei Gu

    Full Text Available Cholangiocarcinoma, also known as bile duct cancer, is the second most common primary hepatic carcinoma with a median survival of less than 2 years. The molecular mechanisms underlying the development of this disease are not clear. To survey activated tyrosine kinases signaling in cholangiocarcinoma, we employed immunoaffinity profiling coupled to mass spectrometry and identified DDR1, EPHA2, EGFR, and ROS tyrosine kinases, along with over 1,000 tyrosine phosphorylation sites from about 750 different proteins in primary cholangiocarcinoma patients. Furthermore, we confirmed the presence of ROS kinase fusions in 8.7% (2 out of 23 of cholangiocarcinoma patients. Expression of the ROS fusions in 3T3 cells confers transforming ability both in vitro and in vivo, and is responsive to its kinase inhibitor. Our data demonstrate that ROS kinase is a promising candidate for a therapeutic target and for a diagnostic molecular marker in cholangiocarcinoma. The identification of ROS tyrosine kinase fusions in cholangiocarcinoma, along with the presence of other ROS kinase fusions in lung cancer and glioblastoma, suggests that a more broadly based screen for activated ROS kinase in cancer is warranted.

    The Lactobacillus acidophilus homology group comprises Gram-positive species that include L. acidophilus, L. helveticus, L. crispatus, L. amylovorus, L. gallinarum, L. delbrueckii subsp. bulgaricus, L. gasseri, and L. johnsonii. While these bacteria are closely related, they have varied ecological lifestyles as dairy and food fermenters, allochthonous probiotics, or autochthonous commensals of the host gastrointestinal tract. Bacterial cell surface components play a critical role in the molecular dialogue between bacteria and interaction signaling with the intestinal mucosa. Notably, the L. acidophilus complex is distinguished in two clades by the presence or absence of S-layers, which are semiporous crystalline arrays of self-assembling proteinaceous subunits found as the outermost layer of the bacterial cell wall. In this study, S-layer-associated proteins (SLAPs) in the exoproteomes of various S-layer-forming Lactobacillus species were proteomically identified, genomically compared, and transcriptionally analyzed. Four gene regions encoding six putative SLAPs were conserved in the S-layer-forming Lactobacillus species but not identified in the extracts of the closely related progenitor, L. delbrueckii subsp. bulgaricus, which does not produce an S-layer. Therefore, the presence or absence of an S-layer has a clear impact on the exoproteomic composition of Lactobacillus species. This proteomic complexity and differences in the cell surface properties between S-layer- and non-S-layer-forming lactobacilli reveal the potential for SLAPs to mediate intimate probiotic interactions and signaling with the host intestinal mucosa.

    Tuberculosis (TB) incidence is decreasing worldwide and eradication is becoming plausible. In low-incidence countries, intervention on migrant populations is considered one of the most important strategies for elimination. However, such measures are inappropriate in European areas where TB is largely endemic, such as Porto in Portugal. We aim to understand transmission chains in Porto through a genetic characterization of Mycobacterium tuberculosis strains and through a detailed epidemiological evaluation of cases. We genotyped the M. tuberculosis strains using the MIRU-VNTR system. We performed an evolutionary reconstruction of the genotypes with median networks, used in this context for the first time. TB cases from a period of two years were evaluated combining genetic, epidemiological and georeferencing information. The data reveal a unique complex scenario in Porto where the autochthonous population acts as a genetic reservoir of M. tuberculosis diversity with discreet episodes of transmission, mostly undetected using classical epidemiology alone. Although control policies have been successful in decreasing incidence in Porto, the discerned complexity suggests that, for elimination to be a realistic goal, strategies need to be adjusted and coupled with a continuous genetic characterization of strains and detailed epidemiological evaluation, in order to successfully identify and interrupt transmission chains.

    Placozoans, flat free-living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest-branching metazoan phyla. They are widely distributed from temperate to tropical oceans. Based on mitochondrial 16S rRNA sequences, 19 haplotypes forming seven distinct clades have been reported in placozoans to date. In Japan, placozoans have been found at nine locations, but 16S genotyping has been performed at only two of these locations. Here, we propose a new processing protocol, "ethanol-treated substrate sampling," for collecting placozoans from natural environments. We also report the collection of placozoans from three new locations, the islands of Shikine-jima, Chichi-jima, and Haha-jima, and we present the distribution of the 16S haplotypes of placozoans in Japan. Multiple surveys conducted at multiple locations yielded five haplotypes that were not reported previously, revealing high genetic diversity in Japan, especially at Shimoda and Shikine-jima Island. The observed geographic distribution patterns were different among haplotypes; some were widely distributed, while others were sampled only from a single location. However, samplings conducted on different dates at the same sites yielded different haplotypes, suggesting that placozoans of a given haplotype do not inhabit the same site constantly throughout the year. Continued sampling efforts conducted during all seasons at multiple locations worldwide and the development of molecular markers within the haplotypes are needed to reveal the geographic distribution pattern and dispersal history of placozoans in greater detail.

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

  8. A primary survey on bryophyte species reveals two novel classes of nucleotide-binding site (NBS genes.

    Directory of Open Access Journals (Sweden)

    Jia-Yu Xue

    Full Text Available Due to their potential roles in pathogen defense, genes encoding nucleotide-binding site (NBS domain have been particularly surveyed in many angiosperm genomes. Two typical classes were found: one is the TIR-NBS-LRR (TNL class and the other is the CC-NBS-LRR (CNL class. It is seldom known, however, what kind of NBS-encoding genes are mainly present in other plant groups, especially the most ancient groups of land plants, that is, bryophytes. To fill this gap of knowledge, in this study, we mainly focused on two bryophyte species: the moss Physcomitrella patens and the liverwort Marchantia polymorpha, to survey their NBS-encoding genes. Surprisingly, two novel classes of NBS-encoding genes were discovered. The first novel class is identified from the P. patens genome and a typical member of this class has a protein kinase (PK domain at the N-terminus and a LRR domain at the C-terminus, forming a complete structure of PK-NBS-LRR (PNL, reminiscent of TNL and CNL classes in angiosperms. The second class is found from the liverwort genome and a typical member of this class possesses an α/β-hydrolase domain at the N-terminus and also a LRR domain at the C-terminus (Hydrolase-NBS-LRR, HNL. Analysis on intron positions and phases also confirmed the novelty of HNL and PNL classes, as reflected by their specific intron locations or phase characteristics. Phylogenetic analysis covering all four classes of NBS-encoding genes revealed a closer relationship among the HNL, PNL and TNL classes, suggesting the CNL class having a more divergent status from the others. The presence of specific introns highlights the chimerical structures of HNL, PNL and TNL genes, and implies their possible origin via exon-shuffling during the quick lineage separation processes of early land plants.

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

    Massive groundwater extraction is very common in Mexico and is well known to result in land subsidence. However, most surveys dedicated to land subsidence focus on one single city, mainly Mexico City, and thus fail to provide a comprehensive picture of the problem. Here we use a space-based radar remote sensing technique, known as Interferometric Synthetic Aperture Radar (InSAR) to detect land subsidence in the entire central Mexico area. We used data from the Japanese satellite ALOS, processed over 600 SAR images acquired between 2007-2011 and produced over 3000 interferograms to cover and area of 200,000 km2 in central Mexico. We identify land subsidence in twenty-one areas, including seventeen cities, namely from east to west, Puebla, Mexico city, Toluca de Lerdo, Queretaro, San Luis de la Paz, south of San Luis de la Paz, Celaya, south of Villa de Reyes, San Luis Potosi, west of Villa de Arista, Morelia, Salamanca, Irapuato, Silao, Leon, Aguascalientes, north of Aguascalientes, Zamora de Hidalgo, Guadalajara, Ahuacatlan, and Tepic. Subsidence rates of 30 cm/yr are observed in Mexico City, while in the other locations typical rates of 5-10 cm/yr are noticed. Regional surveys of this type are necessary for the development of hazard mitigation plans and efficient use of ground-based monitoring. We additionally correlate subsidence with land use, surface geology, and faults distribution and suggest that groundwater extraction for agricultural, urban, and industrial uses are the main causes of land subsidence. We also reveal that the limits of the subsiding areas often correlate with existing faults, motion on these faults being driven by water extraction rather than by tectonic activity. In all the subsiding locations we observe high ground velocity gradients emphasizing the significant risks associated with land subsidence in central Mexico. Averaged 2007-2011 ground velocity map from ALOS InSAR time-series in central Mexico, revealing land subsidence in 21

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

    2013-06-01

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

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

    The northern Gulf of Mexico, including the subaqueous Mississippi River delta front (MRDF), has been productive for oil and gas development since the early 1900s. In 1969 cyclic seafloor wave loading associated with the passage of Hurricane Camille triggered subaqueous mudflows across the MRDF, destroying several offshore oil platforms. This incident spurred geophysical and geotechnical studies of the MRDF, which found that the delta front is prone to mass failures on gentle gradients (gas production, and (3) the frequent passage of tropical cyclones. In June 2014, a geophysical pilot study was conducted 8 km southwest of Southwest Pass, the distributary that currently receives the largest fraction of Mississippi River sediment supply. The resultant dataset encompasses 216 km of subbottom Chirp seismic profiles and a 60 km2 grid of bathymetry and sidescan data. Preliminary interpretation of these data shows the survey area can be classified into four primary sedimentary facies: mudflow gullies, mudflow lobes, undisturbed prodelta, and undisturbed delta front. Subbottom profiles reveal extensive biogenic gas from 20 to about 80 m water depths on the delta front; sidescan data show a variety of bottleneck slides, mudflow gullies and mudflow noses. Previous studies have attempted to constrain the periodicity and magnitude of subaqueous mudslides on the MRDF. However, large age gaps and varied resolution between datasets result in ambiguity regarding the cause and magnitude of observed bathymetric changes. We present high-temporal resolution MRDF bathymetric variations from 2005 (post Hurricane Katrina), 2009 (relatively quiescent storm period), and 2014 (post 2011 Mississippi River flood). These data yield better magnitude and timing estimates of mass movements. This exercise represents a first step towards (1) assembling a comprehensive geologic dataset upon which future MRDF geohazard assessments can be founded, and (2) understanding the dynamics of a massive

    A set of articles presents the activities and missions undertaken by the IRSN in order to control, understand and predict the behaviour of radionuclides in the sea. Twenty three measurement stations are located along the French coasts to survey the radioactivity of water, of sediments, and of sea flora and fauna. Through various programs and projects, researchers are developing always more refined models to simulate and predict the behaviour of radioactive releases in the sea, and their consequences. Beside, the IRSN intervenes as an expert, for example to assess whether there is radiological risk for workers and sea food when dredging sediments in the harbour of La Rochelle

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

  3. Interviewer Effects on a Network-Size Filter Question

    2016-06-01

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

    The I-GALFA survey mapping all the H I in the inner Galactic disk visible to the Arecibo 305m telescope within 10 degrees of the Galactic plane (longitudes of 32 to 77 degrees at b = 0) completed observations in 2009 September and will soon be made publicly available. The high (3.4 arcmin) resolution and tremendous sensitivity of the survey offer a great opportunity to observe the fine details of H I both in the inner and in the far outer Galaxy. The reduced HI column density maps show that the HI structure is highly filamentary and clumpy, pervaded by shell-like structures, vertical filaments, and small clumps. By inspecting individual maps, we have found 36 shell candidates of angular sizes ranging from 0.4 to 12 degrees, half of which appear to be expanding. In order to characterize the filamentary/clumpy morphology of the HI structure, we have carried out statistical analyses of selected areas representing the spiral arms in the inner and outer Galaxy. Genus statistics that can distinguish the ``meatball'' and ``swiss-cheese'' topologies show that the HI topology is clump-like in most regions. The two-dimensional Fourier analysis further shows the HI structures are filamentary and mainly parallel to the plane in the outer Galaxy. We also examine the level-crossing statistics, the results of which are described in detail in an accompanying poster by Park et al.

  5. Seasonal and Diel Activity Patterns of Eight Sympatric Mammals in Northern Japan Revealed by an Intensive Camera-Trap Survey.

    Directory of Open Access Journals (Sweden)

    Takashi Ikeda

    Full Text Available The activity patterns of mammals are generally categorized as nocturnal, diurnal, crepuscular (active at twilight, and cathemeral (active throughout the day. These patterns are highly variable across regions and seasons even within the same species. However, quantitative data is still lacking, particularly for sympatric species. We monitored the seasonal and diel activity patterns of terrestrial mammals in Hokkaido, Japan. Through an intensive camera-trap survey a total of 13,279 capture events were recorded from eight mammals over 20,344 camera-trap days, i.e., two years. Diel activity patterns were clearly divided into four categories: diurnal (Eurasian red squirrels, nocturnal (raccoon dogs and raccoons, crepuscular (sika deer and mountain hares, and cathemeral (Japanese martens, red foxes, and brown bears. Some crepuscular and cathemeral mammals shifted activity peaks across seasons. Particularly, sika deer changed peaks from twilight during spring-autumn to day-time in winter, possibly because of thermal constraints. Japanese martens were cathemeral during winter-summer, but nocturnal in autumn. We found no clear indication of predator-prey and competitive interactions, suggesting that animal densities are not very high or temporal niche partitioning is absent among the target species. This long-term camera-trap survey was highly cost-effective and provided one of the most detailed seasonal and diel activity patterns in multiple sympatric mammals under natural conditions.

    We are presenting new magnetic and gravity data of a high-resolution aerogephysical survey over the area of the Sør Rondane Mountains in the eastern Dronning Maud Land (DML). The aircraft survey is part of the joint geological and geophysical GEA campaign (Geodynamic Evolution of East Antarctica) of the Federal Agency for Geosciences and Natural Resources (BGR) and Alfred-Wegener-Institute for Polar and Marine Research (AWI), in cooperation with the Universities of Ghent, Bremen and Bergen. It was completed during the Antarctic summer season 2012/13, covering an area of more than 100000 square kilometer with a line spacing of 5 km. The data will be correlated with geological structures exposed in the mountain range as well as matched and merged with the data sets of the eastern and southern DML (acquired by AWI during the last decade) for comparison and discussion in the greater context of the tectonic evolution of East Antarctica. Preliminary results show that the magnetic anomaly pattern over the Sør Rondane Mountains differs from the pattern found over the central DML mountains as well as from the low amplitude pattern in between both regions, indicating a significant difference in the evolution of this region, which is in accordance with latest geological findings in this region.

  8. Predicting Where a Radiation Will Occur: Acoustic and Molecular Surveys Reveal Overlooked Diversity in Indian Ocean Island Crickets (Mogoplistinae: Ornebius.

    Directory of Open Access Journals (Sweden)

    Ben H Warren

    Full Text Available Recent theory suggests that the geographic location of island radiations (local accumulation of species diversity due to cladogenesis can be predicted based on island area and isolation. Crickets are a suitable group for testing these predictions, as they show both the ability to reach some of the most isolated islands in the world, and to speciate at small spatial scales. Despite substantial song variation between closely related species in many island cricket lineages worldwide, to date this characteristic has not received attention in the western Indian Ocean islands; existing species descriptions are based on morphology alone. Here we use a combination of acoustics and DNA sequencing to survey these islands for Ornebius crickets. We uncover a small but previously unknown radiation in the Mascarenes, constituting a three-fold increase in the Ornebius species diversity of this archipelago (from two to six species. A further new species is detected in the Comoros. Although double archipelago colonisation is the best explanation for species diversity in the Seychelles, in situ cladogenesis is the best explanation for the six species in the Mascarenes and two species of the Comoros. Whether the radiation of Mascarene Ornebius results from intra- or purely inter- island speciation cannot be determined on the basis of the phylogenetic data alone. However, the existence of genetic, song and ecological divergence at the intra-island scale is suggestive of an intra-island speciation scenario in which ecological and mating traits diverge hand-in-hand. Our results suggest that the geographic location of Ornebius radiations is partially but not fully explained by island area and isolation. A notable anomaly is Madagascar, where our surveys are consistent with existing accounts in finding no Ornebius species present. Possible explanations are discussed, invoking ecological differences between species and differences in environmental history between

    Seabirds are considered to be useful and practical indicators of the state of marine ecosystems because they integrate across changes in the lower trophic levels and the physical environment. Signals from this key group of species can indicate broad scale impacts or response to environmental change. Recent studies of penguin populations, the most commonly abundant Antarctic seabirds in the west Antarctic Peninsula and western Ross Sea, have demonstrated that physical changes in Antarctic marine environments have profound effects on biota at high trophic levels. Large populations of the circumpolar-breeding Adélie penguin occur in East Antarctica, but direct, standardized population data across much of this vast coastline have been more limited than in other Antarctic regions. We combine extensive new population survey data, new population estimation methods, and re-interpreted historical survey data to assess decadal-scale change in East Antarctic Adélie penguin breeding populations. We show that, in contrast to the west Antarctic Peninsula and western Ross Sea where breeding populations have decreased or shown variable trends over the last 30 years, East Antarctic regional populations have almost doubled in abundance since the 1980's and have been increasing since the earliest counts in the 1960's. The population changes are associated with five-year lagged changes in the physical environment, suggesting that the changing environment impacts primarily on the pre-breeding age classes. East Antarctic marine ecosystems have been subject to a number of changes over the last 50 years which may have influenced Adélie penguin population growth, including decadal-scale climate variation, an inferred mid-20th century sea-ice contraction, and early-to-mid 20th century exploitation of fish and whale populations.

    We present six galaxies at z˜ 2 that show evidence of Lyman continuum (LyC) emission based on the newly acquired UV imaging of the Hubble Deep UV legacy survey (HDUV) conducted with the WFC3/UVIS camera on the Hubble Space Telescope (HST). At the redshift of these sources, the HDUV F275W images partially probe the ionizing continuum. By exploiting the HST multiwavelength data available in the HDUV/GOODS fields, models of the UV spectral energy distributions, and detailed Monte Carlo simulations of the intergalactic medium absorption, we estimate the absolute ionizing photon escape fractions of these galaxies to be very high—typically > 60 % (> 13 % for all sources at 90% likelihood). Our findings are in broad agreement with previous studies that found only a small fraction of galaxies with high escape fraction. These six galaxies compose the largest sample yet of LyC leaking candidates at z˜ 2 whose inferred LyC flux has been observed at HST resolution. While three of our six candidates show evidence of hosting an active galactic nucleus, two of these are heavily obscured and their LyC emission appears to originate from star-forming regions rather than the central nucleus. Extensive multiwavelength data in the GOODS fields, especially the near-IR grism spectra from the 3D-HST survey, enable us to study the candidates in detail and tentatively test some recently proposed indirect methods to probe LyC leakage. High-resolution spectroscopic follow-up of our candidates will help constrain such indirect methods, which are our only hope of studying f esc at z˜ 5-9 in the JWST era.

    Full Text Available Abstract Background 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. Methods 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. Results 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.

    Great earthquakes with tsunamis with recurrence intervals of 100-200 years have occurred along the Nankai Trough near central Japan where the Shikoku Basin is subducting with thick sediments on the Philippine Sea plate. To predict the exact height of the tsunami on the coast region generated by these large ruptures, it is important to estimate the vertical deformation that occurs on the seaward end of the rupture area. Recent drilling results have also yielded evidence not only of splay faults that generate tsunamigenic rupture, but also new evidence of tsunamigenic rupture along the frontal thrust at the trench axis in the Nankai Trough. In order to understand the deformation around the frontal thrust at the trench axis, we conducted a dense high-resolution seismic reflection survey with 10-20 km spacing over 1500 km of line length during 2013 and 2014. Clear seismic reflection images of frontal thrusts in the accretionary prism and subducting Shikoku Basin, image deformation along the trench axis between off Muroto Cape and off Ashizuri Cape. The cumulative displacement along the frontal thrust and second thrust are measured from picked distinct reflectors in depth-converted profiles. The average value of cumulative displacement of the frontal thrust is more than 100 m within 2 km depth beneath the seafloor. The location of highest displacement of 300 m displacement agree with the seaward end of slip distribution of the 1946 Nankai event calculated by numerical simulations. We also evaluate the seaward structure for understanding the future rupture distribution. The protothrust zone (PTZ) consisting of many incipient thrusts is identifiable in the portion of trough-fill sediments seaward of the frontal thrust. In order to emphasize the characteristics of frontal thrust and PTZ, we construct the detailed relief image for focusing on the lineated slope of the PTZ at the trough axis. Although our surveys covered a part of Nankai seismogenic zone, it is important to

    Pymont, C; Schofield, T P; Butterworth, P

    2017-12-01

    While international research shows that receipt of welfare benefits is associated with poor mental health, less is known about the relationship between welfare receipt and mental health service use. We investigate whether within-person change in welfare recipient status is associated with change in mental health service use. Analysis of two waves of data from an Australian national household survey. Random- and fixed-effect models considered the effect of change in welfare receipt status, and assessed whether change in mental health service use differed by type of welfare benefit or the direction of welfare transition. Individuals were more likely to report greater mental health service use at times of welfare receipt. These associations were attenuated, but remained significant, after adjusting for mental health. Increased health service use was not tied to specific types of welfare benefits. The increase in mental health service use associated with a transition onto welfare benefits was much greater than the decline in service use associated with the transition off benefits. Within individuals, welfare receipt is associated with greater mental health service use. While this does reflect poorer mental health at the time of welfare receipt, other factors seem to facilitate health service use. © The Author 2016.

    Active galactic nuclei (AGN) are thought to play a critical role in shaping galaxies, but their effect on the circumgalactic medium (CGM) is not well studied. We present results from the COS-AGN survey: 19 quasar sightlines that probe the CGM of 20 optically-selected AGN host galaxies with impact parameters 80 frame equivalent widths EW≥124 mÅ) whilst many of the metal ions are not detected in individual sightlines. A sightline-by-sightline comparison between COS-AGN and the control sample yields no significant difference in EW distribution. However, stacked spectra of the COS-AGN and control samples show significant (>3σ) enhancements in the EW of both Siiii And Lyα at impact parameters >164 kpc by a factor of +0.45 ± 0.05 dex and >+0.75 dex respectively. The lack of detections of both high-ionization species near the AGN and strong kinematic offsets between the absorption systemic galaxy redshifts indicates that neither the AGN's ionization nor its outflows are the origin of these differences. Instead, we suggest the observed differences could result from either AGN hosts residing in haloes with intrinsically distinct gas properties, or that their CGM has been affected by a previous event, such as a starburst, which may also have fuelled the nuclear activity.

    We measured the emergence ages of four marine terraces in the Chikura lowland, which lies to the southeast of the Boso Peninsula, in eastern Japan, to reevaluate the history of the great earthquake occurrences along the Sagami Trough over the past 10,000 years. The dates of the marine terraces are measured via radiocarbon dating of shell fossils obtained from the marine deposits. The sampling method employed in this study collects core samples using a dense and systematic drilling survey, which increased the reliability when correlating shell fossils with marine terraces. In addition, radiocarbon dating was performed with accelerator mass spectrometry, which produces more highly accurate measurements than those measured in previous studies. Moreover, we explored the surface profiles of the terraces with detailed digital elevation model (DEM) data obtained using LiDAR. The maximum emergence ages of the marine terraces were dated at 6300 cal yBP, 3000 cal yBP, and 2200 cal yBP from the top terrace excepting the lowest terrace (which was estimated at AD1703). In addition, another previously unrecognized terrace was detected between the highest and the second terrace in both the dating and the geomorphological analyses and was dated at 5800 cal yBP. The newly obtained ages are nearly a thousand of years younger than previously estimated ages; consequently, the intervals of the great earthquakes that occurred along the Sagami Trough are estimated to be much shorter and more varied than those of previous estimations. This result revises the data used in the current assessment of the probabilities of earthquakes along the Sagami Trough, which could devastate the Tokyo metropolitan area. Furthermore, it demonstrates that the current approach could be a powerful tool to increase the accuracy of assessments of the other areas with depositional marine terraces.

  20. Legacies of stream channel modification revealed using General Land Office surveys, with implications for water temperature and aquatic life

    Full Text Available Land use legacies can have a discernible influence in present-day watersheds and should be accounted for when designing conservation strategies for riverine aquatic life. We describe the environmental history of three watersheds within the Grande Ronde subbasin of the Columbia River using General Land Office survey field notes from the 19th century. In the two watersheds severely impacted by Euro-American land use, stream channel widths—a metric representing habitat simplification—increased from an average historical width of 16.8 m to an average present width of 20.8 m in large streams; 4.3 m to 5.5 m in small, confined or partly confined streams; and 3.5 m to 6.5 m in small, laterally unconfined steams. Conversely, we did not detect significant change in stream widths in an adjacent, wilderness stream with minimal human impact. Using a mechanistic water temperature model and restoration scenarios based on the historical condition, we predicted that stream restoration in the impacted watersheds could notably decrease average water temperatures—especially when channel narrowing is coupled with riparian restoration—up to a 6.6°C reduction in the upper Grande Ronde River and 3.0°C in Catherine Creek. These reductions in water temperature translated to substantial changes in the percentage of stream network habitable to salmon and steelhead migration (from 29% in the present condition to 79% in the fully restored scenario and to core juvenile rearing (from 13% in the present condition to 36% in the fully restored scenario. We conclude that land use legacies leave an important footprint on the present landscape and are critical for understanding historic habitat-forming processes as a necessary first step towards restoration.

  1. Characterizing interstellar filaments as revealed by the Herschel Gould Belt survey: Insights into the initial conditions for star formation

    Arzoumanian, Doris

    2012-01-01

    This thesis aims to characterize the physical properties of interstellar filaments imaged in nearby molecular clouds with the Herschel Space Observatory as part of the Herschel Gould Belt survey. In order to get insight into the formation and evolution of interstellar filaments I analyzed, during my PhD work, a large sample of filaments detected in various nearby clouds. The observed density profiles of the filaments show a power law behavior at large radii and their dust temperature profiles show a drop towards the center. The filaments are characterized by a narrow distribution of de-convolved inner widths, centered around a typical value of ∼ 0.1 pc, while they span more than three orders of magnitude in central column density. This typical filament width corresponds to the sonic scale below which interstellar turbulence becomes subsonic in diffuse gas, which may suggest that the filaments form as a result of the dissipation of large-scale turbulence. While the turbulent fragmentation picture provides a plausible mechanism for forming interstellar filaments, the fact that pre-stellar cores tend to form in dense, gravitationally unstable filaments suggests that gravity is a major driver in the subsequent evolution of the dense supercritical filaments. The latter hypothesis is supported by molecular line observations with the IRAM 30 m telescope, which show an increase in the non-thermal velocity dispersion of supercritical filaments as a function of their central column density, suggesting that self gravitating filaments grow in mass per unit length by accretion of background material while at the same time fragmenting into star-forming cores.

  2. A Technique Socratic Questioning-Guided Discovery

    2012-03-01

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

    Ubinas volcano, the historically most active volcano in Peru straddles a low-relief high plateau and the flank of a steep valley. A multidisciplinary geophysical study has been performed to investigate the internal structure and the fluids flow within the edifice. We conducted 10 self-potential (SP) radial (from summit to base) profiles, 15 audio magnetotelluric (AMT) soundings on the west flank and a detailed survey of SP and soil temperature measurements on the summit caldera floor. The typical “V” shape of the SP radial profiles has been interpreted as the result of a hydrothermal zone superimposed on a hydrogeological zone in the upper parts of the edifice, and depicts a sub-circular SP positive anomaly, about 6 km in diameter. The latter is centred on the summit, and is characterised by a larger extension on the western flank located on the low-relief high plateau. The AMT resistivity model shows the presence of a conductive body beneath the summit at a depth comparable to that of the bottom of the inner south crater in the present-day caldera, where intense hydrothermal manifestations occur. The lack of SP and temperature anomalies on the present caldera floor suggests a self-sealed hydrothermal system, where the inner south crater acts as a pressure release valve. Although no resistivity data exists on the eastern flank, we presume, based on the asymmetry of the basement topography, and the amplitude of SP anomalies on the east flank, which are approximately five fold that on the west flank, that gravitational flow of hydrothermal fluids may occur towards the deep valley of Ubinas. This hypothesis, supported by the presence of hot springs and faults on the eastern foot of the edifice, reinforces the idea that a large part of the southeast flank of the Ubinas volcano may be altered by hydrothermal activity and will tend to be less stable. One of the major findings that stems from this study is that the slope of the basement on which a volcano has grown

    Full Text Available The advent of next-generation sequencing tools has made it possible to conduct fine-scale surveys of population differentiation and genome-wide scans for signatures of selection in non-model organisms. Such surveys are of particular importance in sharply declining coral species, since knowledge of population boundaries and signs of local adaptation can inform restoration and conservation efforts. Here, we use genome-wide surveys of single-nucleotide polymorphisms in the threatened Caribbean elkhorn coral, Acropora palmata, to reveal fine-scale population structure and infer the major barrier to gene flow that separates the eastern and western Caribbean populations between the Bahamas and Puerto Rico. The exact location of this break had been subject to discussion because two previous studies based on microsatellite data had come to differing conclusions. We investigate this contradiction by analyzing an extended set of 11 microsatellite markers including the five previously employed and discovered that one of the original microsatellite loci is apparently under selection. Exclusion of this locus reconciles the results from the SNP and the microsatellite datasets. Scans for outlier loci in the SNP data detected 13 candidate loci under positive selection, however there was no correlation between available environmental parameters and genetic distance. Together, these results suggest that reef restoration efforts should use local sources and utilize existing functional variation among geographic regions in ex situ crossing experiments to improve stress resistance of this species.

    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 (r s  = 0.5052, p LGBTQ patients.

    1983-01-01

    The author analyses the development of the world petroleum market and its pricing factors to the present on the basis of the theory of ground rent, in which the part played by absolute ground rent, differential rent, and free and national state property in the capitalist mode of production is determined. His investigation of economic policy traces the absorbing history of the petroleum production and policy of the United States of America, which for so long governed the world market, the development of Venezuela into a petroleum country (whose true history is here revealed for the first time), the penetration of the middle East by the international petroleum leaseholders' capital and their cartel, the formation of the OPEC, and finally the 'victory' of the lather over the petroleum combines in the international petroleum crisis of 1970-1973. The book closes with a survey at the start of the 80s and an outlook into the foreseeable future. What is really hidden behind the quarrels about prices, profit, taxes, royalties, franchise agreements, production quotas, nationalization and so forth and behind the economic, political, and even moral arguments of the parties concerned turns out to be the fight of the petroleum ground proprietors for the ground rent - but to win a victory in this fight means ultimately to face its limitations, too. Blindness to the economic and political importance of ground rent, right from the theoretical approach, also created a major cause of the false diagnoses and forecasts on the petroleum market western economic scientists were misled into, and thus of the surprise effect that came in the form of the petroleum crisis of the early 1970s.

    Directory of Open Access Journals (Sweden)

    R. C. Hamdy MD

    2018-01-01

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

    R. C. Hamdy MD

    2018-02-01

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

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

In general, risk preference is closely related to socioeconomic status (SES, which includes factors such as age, sex, income, and educational attainment.Objective: We aimed to determine the effect of SES and behavioral propensity on the progress of diabetic complications in patients with type 2 diabetes mellitus (T2DM.Methods: We conducted a survey of 238 patients with difficult-to-control T2DM treated at a hospital in Japan using a modified behavioral economics questionnaire that included questions related to SES. The patients had been referred by general practitioners or other departments in the hospital because of poor metabolic control or unstable complications.Results: Educational attainment was significantly associated with progression of retinopathy in patients <65 years of age. Educational attainment of a high school diploma (12 years of education or lower was a significant risk factor, but there were no differences among levels of attainment beyond high school (13–16 years or more of education. Behavioral propensities were also weakly associated with complications, but not as much as educational attainment. Personal income level and economic status did not show an association with the retinopathy levels.Conclusion: Lower educational attainment is a strong risk factor for diabetic retinopathy, and it is independent of the economic status. The result suggests that cognitive function may play an important role in the progression of diabetic retinopathy in

  20. Regal phylogeography: Range-wide survey of the marine angelfish Pygoplites diacanthus reveals evolutionary partitions between the Red Sea, Indian Ocean, and Pacific Ocean.

    The regal angelfish (Pygoplites diacanthus; family Pomacanthidae) occurs on reefs from the Red Sea to the central Pacific, with an Indian Ocean/Rea Sea color morph distinct from a Pacific Ocean morph. To assess population differentiation and evaluate the possibility of cryptic evolutionary partitions in this monotypic genus, we surveyed mtDNA cytochrome b and two nuclear introns (S7 and RAG2) in 547 individuals from 15 locations. Phylogeographic analyses revealed four mtDNA lineages (d=0.006-0.015) corresponding to the Pacific Ocean, the Red Sea, and two admixed lineages in the Indian Ocean, a pattern consistent with known biogeographic barriers. Christmas Island in the eastern Indian Ocean had both Indian and Pacific lineages. Both S7 and RAG2 showed strong population-level differentiation between the Red Sea, Indian Ocean, and Pacific Ocean (ΦST=0.066-0.512). The only consistent population sub-structure within these three regions was at the Society Islands (French Polynesia), where surrounding oceanographic conditions may reinforce isolation. Coalescence analyses indicate the Pacific (1.7Ma) as the oldest extant lineage followed by the Red Sea lineage (1.4Ma). Results from a median-joining network suggest radiations of two lineages from the Red Sea that currently occupy the Indian Ocean (0.7-0.9Ma). Persistence of a Red Sea lineage through Pleistocene glacial cycles suggests a long-term refuge in this region. The affiliation of Pacific and Red Sea populations, apparent in cytochrome b and S7 (but equivocal in RAG2) raises the hypothesis that the Indian Ocean was recolonized from the Red Sea, possibly more than once. Assessing the genetic architecture of this widespread monotypic genus reveals cryptic evolutionary diversity that merits subspecific recognition. We recommend P.d. diacanthus and P.d. flavescens for the Pacific and Indian Ocean/Red Sea forms. Copyright © 2016 Elsevier Inc. All rights reserved.

    The regal angelfish (Pygoplites diacanthus; family Pomacanthidae) occupies reefs from the Red Sea to the central Pacific, with an Indian Ocean/Rea Sea color morph distinct from a Pacific Ocean morph. To assess population differentiation and evaluate the possibility of cryptic evolutionary partitions in this monotypic genus, we surveyed mtDNA cytochrome b and two nuclear introns (S7 and RAG2) in 547 individuals from 15 locations. Phylogeographic analyses revealed four mtDNA lineages (d = 0.006 – 0.015) corresponding to the Pacific Ocean, the Red Sea, and two admixed lineages in the Indian Ocean, a pattern consistent with known biogeographical barriers. Christmas Island in the eastern Indian Ocean had both Indian and Pacific lineages. Both S7 and RAG2 showed strong population-level differentiation between the Red Sea, Indian Ocean, and Pacific Ocean (ΦST = 0.066 – 0.512). The only consistent population sub-structure within these three regions was at the Society Islands (French Polynesia), where surrounding oceanographic conditions may reinforce isolation. Coalescence analyses indicate the Pacific (1.7 Ma) as the oldest extant lineage followed by the Red Sea lineage (1.4 Ma). Results from a median-joining network suggest radiations of two lineages from the Red Sea that currently occupy the Indian Ocean (0.7 – 0.9 Ma). Persistence of a Red Sea lineage through Pleistocene glacial cycles suggests a long-term refuge in this region. The affiliation of Pacific and Red Sea populations, apparent in cytochrome b and S7 (but equivocal in RAG2) raises the hypthosis that the Indian Ocean was recolonized from the Red Sea, possibly more than once. Assessing the genetic architecture of this widespread monotypic genus reveals cryptic evolutionary diversity that merits subspecific recognition.

    Full Text Available Excessive car evacuation can cause severe traffic jams that can lead to large numbers of casualties during tsunami disasters. Investigating the possible factors that lead to unnecessary car evacuation can ensure smoother tsunami evacuations and mitigate casualty damages in future tsunami events. In this study, we quantitatively investigated the possible factors that promote car evacuation, including both necessary and unnecessary usages, by statistically analysing a large amount of data on actual tsunami evacuation behaviours surveyed in Kesennuma, where devastating damage occurred during the 2011 Tohoku Tsunami. A straightforward statistical analysis revealed a high percentage of car evacuations (approx. 50%; however, this fraction includes a high number of unnecessary usage events that were distinguished based on mode choice reasons. In addition, a binary logistic regression was conducted to quantitatively evaluate the effects of several factors and to identify the dominant factor that affected evacuation mode choice. The regression results suggested that the evacuation distance was the dominant factor for choosing car evacuation relative to other factors, such as age and sex. The cross-validation test of the regression model demonstrated that the considered factors were useful for decision making and the prediction of evacuation mode choice in the target area.

  9. 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.

    Hepatitis E virus (HEV) infection is an issue of public health concern in high-income and non-endemic countries. Increasing evidence supports the hypothesis of a zoonotic route as the main mode of infection in this epidemiological setting, since the transmission of genotypes HEV-3 and HEV-4 from reservoirs to humans has been demonstrated. In America, studies have confirmed the circulation of HEV in pig herds but the zoonotic role of wild boars has never been evaluated. Uruguay has a high burden of HEV- associated acute hepatitis, and a close phylogenetic relationship was observed among human HEV-3 strains and European isolates detected in swine. However in this context, swine herds have never been surveyed. Herein is reported a survey of HEV in swine herds, pigs at slaughter-house and free-living wild boar populations. Two-hundred and twenty sera and 150 liver tissue samples from domestic pigs, and 140 sera from wild boars were tested for HEV by ELISA and PCR-based approaches. All tested swine farms resulted seropositive with an overall rate of 46.8%. In turn, 22.1% of the wild boars had anti-HEV antibodies. HEV RNA was detected in 16.6% and 9.3% of liver samples from slaughter-age pigs and adult wild boars sera, respectively. Three strains from domestic pig were also amplified by nested-PCR approaches. By contrast, none of the positive samples obtained from wild boars could be confirmed by nested-PCR. Phylogenetic analysis revealed a very high nucleotide identity among swine strains and sequences obtained from humans in Uruguay. Results showed that HEV is widely distributed among swine herds in Uruguay. Additionally, this study evidences for the first time in the American continent that wild boar populations are a reservoir for HEV, though its zoonotic role remains to be elucidated. Altogether, data presented here suggest a high zoonotic risk of HEV transmission from swine to humans. Copyright © 2017 Elsevier B.V. All rights reserved.

    The world's coral reefs appear to be in a global decline, yet most previous research on coral reefs has taken place at depths shallower than 30 m. Mesophotic coral ecosystem (depths deeper than ~30 m) studies have revealed extensive, productive habitats and rich communities. Despite recent advances, mesophotic coral ecosystems remain understudied due to challenges with sampling at deeper depths. The few previous studies of mesophotic coral ecosystems have shown variation across locations in depth-specific species composition and assemblage shifts, potentially a response to differences in habitat or light availability/water clarity. This study utilized scuba to examine fish and benthic communities from shallow and upper mesophotic (to 45 m) zones of Flower Garden Banks National Marine Sanctuary (FGBNMS, 28°0'N; 93°50'W) from 2010-2012. Dominant planktivores were ubiquitous in shallow and upper mesophotic habitats, and comparisons with previous shallow research suggest this community distribution has persisted for over 30 years. Planktivores were abundant in shallow low-relief habitats on the periphery of the coral reef, and some of these sites that contained habitat transitioning from high to low relief supported high biomass of benthic predators. These peripheral sites at FGBNMS may be important for the trophic transfer of oceanic energy to the benthic coral reef. Distinct differences between upper mesophotic and shallow communities were also observed. These included greater overall fish (as well as apex predator) biomass in the upper mesophotic, differences in apex predator community composition between depth zones, and greater percent cover of algae, rubble, sand, and sponges in the upper mesophotic. Greater fish biomass in the upper mesophotic and similar fish community composition between depth zones provide preliminary support that upper mesophotic habitats at FGBNMS have the capacity to serve as refugia for the shallow-water reefs.

    Ground subsidence and sinkhole collapse are phenomena affecting regions of karst geology worldwide. The rapid development of such phenomena around the Dead Sea in the last four decades poses a major geological hazard to the local population, agriculture and industry. Nonetheless many aspects of this hazard are still incompletely described and understood, especially on the eastern Dead Sea shore. In this work, we present a first low altitude (sinkhole area of Ghor Al-Haditha, Jordan. We provide a detailed qualitative and quantitative analysis of a new, high resolution digital surface model (5 cm px-1) and orthophoto of this area (2.1 km2). We also outline the factors affecting the quality and accuracy of this approach. Our analysis reveals a kilometer-scale sinuous depression bound partly by flexure and partly by non-tectonic faults. The estimated minimum volume loss of this subsided zone is 1.83 ṡ 106 m3 with an average subsidence rate of 0.21 m yr-1 over the last 25 years. Sinkholes in the surveyed area are localized mainly within this depression. The sinkholes are commonly elliptically shaped (mean eccentricity 1.31) and clustered (nearest neighbor ratio 0.69). Their morphologies and orientations depend on the type of sediment they form in: in mud, sinkholes have a low depth to diameter ratio (0.14) and a long-axis azimuth of NNE-NE. In alluvium, sinkholes have a higher ratio (0.4) and are orientated NNW-N. From field work, we identify actively evolving artesian springs and channelized, sediment-laden groundwater flows that appear locally in the main depression. Consequently, subrosion, i.e. subsurface mechanical erosion, is identified as a key physical process, in addition to dissolution, behind the subsidence and sinkhole hazard. Furthermore, satellite image analysis links the development of the sinuous depression and sinkhole formation at Ghor Al-Haditha to preferential groundwater flow paths along ancient and current wadi riverbeds.

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

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

  2. Trick questions: cosmopolitan hospitality

    Directory of Open Access Journals (Sweden)

    Eleanor Byrne

    2013-08-01

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

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

    Directory of Open Access Journals (Sweden)

    Naomi Kamoen

    2013-12-01

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

  4. The pregnancy question: a survey regarding the establishment of whether females of childbearing age are or may be pregnant prior to radiation exposures in diagnostic radiology and nuclear medicine departments in the UK

    Full text: In the UK, the Ionising Radiation (Medical Exposure) Regulations 2000 state that 'the written procedure for medical exposures shall include...procedures for making enquiries of females of childbearing age to establish whether the individual is or may be pregnant...'. Despite the importance of this question and the potential for causing great distress and anxiety if an examination involving ionising radiation is performed on a pregnant patient, the guidance available is vague and there is no universally accepted procedure on when and how to ask this difficult question. Anecdotal evidence suggests that the procedure for enquiring about possible pregnancy varies from department to department. To investigate this further, we devised a questionnaire to send out to diagnostic radiology and nuclear medicine departments across the UK. Questions asked related to the department's written procedure, the examinations for which the question would be asked, the age of women asked and the recording of whether the question was asked and the outcome. Responses were received from over 300 individuals from 66 different hospitals. The majority (73.5%) were from X-ray departments, 14.0% were from nuclear medicine and the remaining 12.5% included computed tomography, neuroradiology, angiography and cardiac catheter labs. 97.0% have a written procedure, 1.2% do not, 0.9% do not know and 0.9% gave no response. Of the responses from X-ray departments, 17% ask the question for all examinations, while 83% ask for examinations of specific body regions. Several body regions were stated and were divided into 9 categories with the main one being diaphragm to knees (45%). Nuclear medicine departments ask for all examinations. With regard to establishing the 'childbearing age', 5% state that for younger and older patients they ascertain whether the female has started/stopped menstruation before asking the pregnancy question (no age range given), and 95% state an age range of the females

    2017-07-01

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

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

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

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

    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 .

  14. 101 questions about energy

    2009-01-01

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

  16. Comparison of Reef Fish Survey Data Gathered by Open and Closed Circuit SCUBA Divers Reveals Differences in Areas With Higher Fishing Pressure.

    Directory of Open Access Journals (Sweden)

    Andrew E Gray

    Full Text Available Visual survey by divers using open-circuit (OC SCUBA is the most widely used approach to survey coral reef fishes. Therefore, it is important to quantify sources of bias in OC surveys, such as the possibility that avoidance of OC divers by fishes can lead to undercounting in areas where targeted species have come to associate divers with a risk of being speared. One potential way to reduce diver avoidance is to utilize closed circuit rebreathers (CCRs, which do not produce the noise and bubbles that are a major source of disturbance associated with OC diving. For this study, we conducted 66 paired OC and CCR fish surveys in the Main Hawaiian Islands at locations with relatively high, moderate, and light fishing pressure. We found no significant differences in biomass estimates between OC and CCR surveys when data were pooled across all sites, however there were differences at the most heavily fished location, Oahu. There, biomass estimates from OC divers were significantly lower for several targeted fish groups, including surgeonfishes, targeted wrasses, and snappers, as well as for all targeted fishes combined, with mean OC biomass between 32 and 68% of mean CCR biomass. There were no clear differences between OC and CCR biomass estimates for these groups at sites with moderate or low fishing pressure, or at any location for other targeted fish groups, including groupers, parrotfishes, and goatfishes. Bias associated with avoidance of OC divers at heavily fished locations could be substantially reduced, or at least calibrated for, by utilization of CCR. In addition to being affected by fishing pressure, the extent to which avoidance of OC divers is problematic for visual surveys varies greatly among taxa, and is likely to be highly influenced by the survey methodology and dimensions used.

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

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

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

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

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

  3. Off-road sampling reveals a different grassland bird community than roadside sampling: implications for survey design and estimates to guide conservation

    2014-06-01

    Full Text Available Grassland bird species continue to decline steeply across North America. Road-based surveys such as the North American Breeding Bird Survey (BBS are often used to estimate trends and population sizes and to build species distribution models for grassland birds, although roadside survey counts may introduce bias in estimates because of differences in habitats along roadsides and in off-road surveys. We tested for differences in land cover composition and in the avian community on 21 roadside-based survey routes and in an equal number of adjacent off-road walking routes in the grasslands of southern Alberta, Canada. Off-road routes (n = 225 point counts had more native grassland and short shrubs and less fallow land and road area than the roadside routes (n = 225 point counts. Consequently, 17 of the 39 bird species differed between the two route types in frequency of occurrence and relative abundance, measured using an indicator species analysis. Six species, including five obligate grassland species, were more prevalent at off-road sites; they included four species listed under the Canadian federal Species At Risk Act or listed by the Committee on the Status of Endangered Wildlife in Canada: Sprague's Pipit (Anthus spragueii, Baird's Sparrow (Ammodramus bairdii, the Chestnut-collared Longspur (Calcarius ornatus, and McCown's Longspur (Rhynchophanes mccownii. The six species were as much as four times more abundant on off-road sites. Species more prevalent along roadside routes included common species and those typical of farmland and other human-modified habitats, e.g., the European Starling (Sturnus vulgaris, the Black-billed Magpie (Pica hudsonia, and the House Sparrow (Passer domesticus. Differences in avian community composition between roadside and off-road surveys suggest that the use of BBS data when generating population estimates or distribution models may overestimate certain common species and underestimate others of conservation

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

  8. Genome-Wide Survey of Pseudomonas aeruginosa PA14 Reveals a Role for the Glyoxylate Pathway and Extracellular Proteases in the Utilization of Mucin

    ABSTRACT Chronic airway infections by the opportunistic pathogen Pseudomonas aeruginosa are a major cause of mortality in cystic fibrosis (CF) patients. Although this bacterium has been extensively studied for its virulence determinants, biofilm growth, and immune evasion mechanisms, comparatively little is known about the nutrient sources that sustain its growth in vivo. Respiratory mucins represent a potentially abundant bioavailable nutrient source, although we have recently shown that canonical pathogens inefficiently use these host glycoproteins as a growth substrate. However, given that P. aeruginosa, particularly in its biofilm mode of growth, is thought to grow slowly in vivo, the inefficient use of mucin glycoproteins may be relevant to its persistence within the CF airways. To this end, we used whole-genome fitness analysis, combining transposon mutagenesis with high-throughput sequencing, to identify genetic determinants required for P. aeruginosa growth using intact purified mucins as a sole carbon source. Our analysis reveals a biphasic growth phenotype, during which the glyoxylate pathway and amino acid biosynthetic machinery are required for mucin utilization. Secondary analyses confirmed the simultaneous liberation and consumption of acetate during mucin degradation and revealed a central role for the extracellular proteases LasB and AprA. Together, these studies describe a molecular basis for mucin-based nutrient acquisition by P. aeruginosa and reveal a host-pathogen dynamic that may contribute to its persistence within the CF airways.

    2017-06-01

    Surveys were conducted in 2014 and 2015 in Southern and Northern Benin, respectively, to identify the viruses infecting peppers (Capsicum spp.). The samples were screened by ELISA for cucumber mosaic virus (CMV), pepper veinal mottle virus (PVMV), potato virus Y (PVY) and tomato yellow leaf curl virus (TYLCV). A generic reverse transcription PCR (RT-PCR) was used to test for the presence of poleroviruses. ELISA tests confirmed the prevalence of all viruses, while the RT-PCR detected pepper vein yellows virus (PeVYV) which is reported for the first time in Benin. A further, divergent polerovirus isolate was detected from a single pepper sample originating from southern Benin. Screening of samples collected from solanaceous plants during virus surveys in Mali (conducted in 2009) also detected this divergent polerovirus isolate in two samples from African eggplants. The complete genome sequence was obtained from the Mali isolate using transcriptome sequencing and by conventional Sanger sequencing of overlapping RT-PCR products. Based on the sequence characteristics of this isolate we propose a new polerovirus species, African eggplant yellowing virus (AeYV).

    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.

    The current information on the prevalence of avian metapneumovirus (aMPV) infection in layers is fragmentary and its true impact on egg production often remains unknown or unclear. In order to draw an epidemiologic picture of aMPV presence in layer flocks in Italy, a survey was performed on 19 flocks of pullets and layers based on longitudinal studies or sporadic samplings. aMPV was detected by reverse transcription (RT)-PCR, and blood samples were collected for serology by aMPV ELISA. Occurrences of respiratory signs and a drop in egg production were recorded. Possible involvement of infectious bronchitis (IB) and egg drop syndrome (EDS) viruses that could have caused loss of egg production we ruled out for IB virus by RT-PCR, and EDS virus was ruled out by hemagglutination-inhibition (HI). Only subtype B of aMPV was found in both pullet and layer farms. Surveys of pullets showed that most groups became infected prior to the onset of lay without showing clear respiratory signs. At the point of lay, these groups were serologically positive to aMPV. In two layer flocks, egg drops were observed and could be strongly linked to the presence of aMPV infection. Results were correlated with aMPV vaccination programs applied to the birds in three flocks on the same farm. Only a vaccination program which included two live and one killed vaccines gave complete protection from aMPV infection to the birds, while a single live vaccine application was not efficacious. The current study gives an inside view of field aMPV diffusion in Italy and its control in layers.

    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. PMID:23024399

    Despite the threat posed to millions of people living in the vicinity of volcanoes, only a fraction of the worldwide ~800 potentially active arc volcanoes have geodetic monitoring. Indonesian and Mexican volcanoes are sparsely monitored with ground-based methods but especially dangerous, emphasizing the need for remote sensing monitoring. In this study we take advantage of over 1200 ALOS InSAR images to survey the entire west Sunda and Mexican volcanic arcs, covering a total of 500 000 km2. We use 2 years of data to monitor the background activity of the Indonesian arc, and 4 years of data at four volcanic edifices (Sinabung, Kerinci, Merapi, and Agung), as well as 4 years of data to survey the Mexican arc. We derive time-dependent ground deformation data using the Small Baseline technique with DEM error correction. We detect seven volcanoes with significant deformation in the west-Sunda arc: six inflating volcanoes (Sinabung, Kerinci, Slamet, Lawu, Lamongan, and Agung) and one deflating volcano (Anak Krakatau). Three of the six inflating centers erupted during or after the observation period. We detect inflation prior to Sinabung's first Holocene eruption in September 2010, followed by a small deflation of the summit area. A similar signal is observed at Kerinci before and after its April 2009 eruption. We also detect uplift prior to Slamet's eruption in April 2009. Agung, in Bali, whose last eruption was in 1964, has been inflating steadily between mid 2007 and early 2009, followed by a period with little deformation until mid-2011. Inflation not followed by eruption is also observed at Lamongan and Lawu, both historically active centers. The close relation between periods of activity and observed deformation suggests that edifice inflation is of magmatic origin and represents the pressurization of reservoirs caused by ascent of new magma. We model the observed deformation and show that the seven deforming Indonesian volcanoes have shallow magma reservoirs at ~1

    2015-11-01

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

    Full Text Available The chromosomal localization of 45S ribosomal RNA genes in Ambystoma jeffersonianum was determined by fluorescence in situ hybridization with 18S rDNA fragment as a probe (FISH-rDNA. Our results revealed the presence of rDNA polymorphism among A.jeffersonianum populations in terms of number, location and FISH signal intensity on the chromosomes. Nine rDNA cytotypes were found in ten geographically isolated populations and most of them contained derivative rDNA sites. Our preliminary study provides strong indication of karyotypic diversification of A.jeffersonianum that is demonstrated by intraspecific variation of 45S rDNA cytotypes. rDNA cytotype polymorphism has been described in many other caudate amphibians. We predict that habitat isolation, low dispersal ability and decline of effective population size could facilitate the fixation and accumulation of variable rDNA cytotypes during their chromosome evolution.

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

    Directory of Open Access Journals (Sweden)

    Yu Zhang

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

    Changes in the area and bathymetry of Imja Glacial Lake and in the elevation of its damming moraine, Khumbu region, Nepal Himalaya are investigated. Previously reported changes in the lake area have been updated by multi-temporal ASTER images, which revealed a decreased expansion rate after 2000. A provisional expansion of the lake observed in 2004, from which some studies concluded an accelerated lake expansion due to global warming, has, from 2005, subsided to the glacier surface. Bathymetric changes for the period 1992-2002 that were first obtained for Himalayan glacial lakes suggest that the melting of debris-covered ice beneath the lake is insignificant in terms of the increase in lake volume, and that the retreat of a glacier in contact with the lake by calving is essential for the lake's expansion. Changes in the height of a damming moraine for the period 2001-2007 suggest a continuous surface lowering near the lake, though the lowering rates are smaller than those for the period 1989-1994.

  1. Alteration of protein levels during influenza virus H1N1 infection in host cells: a proteomic survey of host and virus reveals differential dynamics.

    Directory of Open Access Journals (Sweden)

    Susann Kummer

    Full Text Available We studied the dynamics of the proteome of influenza virus A/PR/8/34 (H1N1 infected Madin-Darby canine kidney cells up to 12 hours post infection by mass spectrometry based quantitative proteomics using the approach of stable isotope labeling by amino acids in cell culture (SILAC. We identified 1311 cell proteins and, apart from the proton channel M2, all major virus proteins. Based on their abundance two groups of virus proteins could be distinguished being in line with the function of the proteins in genesis and formation of new virions. Further, the data indicate a correlation between the amount of proteins synthesized and their previously determined copy number inside the viral particle. We employed bioinformatic approaches such as functional clustering, gene ontology, and pathway (KEGG enrichment tests to uncover co-regulated cellular protein sets, assigned the individual subsets to their biological function, and determined their interrelation within the progression of viral infection. For the first time we are able to describe dynamic changes of the cellular and, of note, the viral proteome in a time dependent manner simultaneously. Through cluster analysis, time dependent patterns of protein abundances revealed highly dynamic up- and/or down-regulation processes. Taken together our study provides strong evidence that virus infection has a major impact on the cell status at the protein level.

    Global climatic transitions and Tibetan Plateau uplifts are hypothesized to have profoundly impacted biodiversity in southeastern Asia. To further test the hypotheses related to the impacts of these incidents, we investigated the diversification patterns of the newt genus Tylototriton sensu lato , distributed across the mountain ranges of southeastern Asia. Gene-tree and species-tree analyses of two mitochondrial genes and two nuclear genes revealed five major clades in the genus, and suggested several cryptic species. Dating estimates suggested that the genus originated in the early-to-middle Miocene. Under different species delimitating scenarios, diversification analyses with birth-death likelihood tests indicated that the genus held a higher diversification rate in the late Miocene-to-Pliocene era than that in the Pleistocene. Ancestral area reconstructions indicated that the genus originated from the northern Indochina Peninsula. Accordingly, we hypothesized that the Miocene Climatic Transition triggered the diversification of the genus, and the reinforcement of East Asian monsoons associated with the stepwise uplifts of the Tibetan Plateau promoted the radiation of the genus in southeastern Asia during the Miocene-to-Pliocene period. Quaternary glacial cycles likely had limited effects on speciation events in the genus, but mainly had contributions on their intraspecific differentiations.

  9. 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.

Organized by CERN and the Department of public instruction of the Canton of Geneva, the meeting followed a reading by the students of the play Die Physiker, by Friedrich Dürrenmatt, which raises the problem of political exploitation of discoveries made during the second world war. The Minister of Education of the Canton de Genève, Mrs Martine Brunschwig-Graf, took part in the debate. The questions posed by students were not lacking in pertinence : Should a physicist reveal a discovery that is dangerous in his opinion ? Who are responsible, those who make the discoveries or those who use them ?

  13. Question-asking behavior as a form of cognitive activity

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

  17. 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.

    2011-01-01

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

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

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

    The year 2016 was an exciting one for the field, with several notable successes outweighing a few setbacks. As the number of patients treated successfully (and safely) with gene therapy grows, the totality of evidence points to a robust platform with utility in orphan/ultra-orphan diseases as well as broader indications, and with hopefully increasing predictability of results. This year promises to feature more patients treated, more clinical data, and more gene therapy products in registration-enabling studies. For the field to continue to advance and mature into the next great drug delivery platform, a few unsolved and remaining questions need to be addressed, including the business model for cures, a broader safety/efficacy profile once more patients are treated, optimization of delivery (including next-generation approaches), and greater understanding of the impact of competitive dynamics. In this report, we detail the success and setbacks of 2016 and highlight the unanswered questions-and how the answers may shape the field in the years ahead.

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.

  1. Les questions de migrations internationales

    Science.gov (United States)

    Samman, Mouna Liliane

    1993-03-01

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

  2. Biology Question Generation from a Semantic Network

    Science.gov (United States)

    Zhang, Lishan

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

    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...

This day tried to bring information to answer the following questions: do people have to keep the plutonium in the UOX fuel or in the MOX fuel in order to use it for future fast reactors? Do people have to continue obstinately the plutonium reprocessing in the MOX for the PWR type reactors? Will it be realized a underground disposal? Can it be technically developed plutonium incinerators and is it economically interesting? The plutonium physics, the experimental programs and the possible solutions are presented. (A.L.B.)

  5. Revealing Rembrandt

    Directory of Open Access Journals (Sweden)

    Andrew J Parker

    2014-04-01

    Full Text Available The power and significance of artwork in shaping human cognition is self-evident. The starting point for our empirical investigations is the view that the task of neuroscience is to integrate itself with other forms of knowledge, rather than to seek to supplant them. In our recent work, we examined a particular aspect of the appreciation of artwork using present-day functional magnetic resonance imaging (fMRI. Our results emphasised the continuity between viewing artwork and other human cognitive activities. We also showed that appreciation of a particular aspect of artwork, namely authenticity, depends upon the co-ordinated activity between the brain regions involved in multiple decision making and those responsible for processing visual information. The findings about brain function probably have no specific consequences for understanding how people respond to the art of Rembrandt in comparison with their response to other artworks. However, the use of images of Rembrandt’s portraits, his most intimate and personal works, clearly had a significant impact upon our viewers, even though they have been spatially confined to the interior of an MRI scanner at the time of viewing. Neuroscientific studies of humans viewing artwork have the capacity to reveal the diversity of human cognitive responses that may be induced by external advice or context as people view artwork in a variety of frameworks and settings.

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

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...

  12. "Hot Seat" Questioning: A Technique to Promote and Evaluate Student Dialogue

    Science.gov (United States)

    Crider, Anthony

    Several approaches have been proposed to include students in classroom dialogue, including "think-pair-share" and "talk to your neighbor." I recently implemented an additional technique in which four students answer questions in a "Hot Seat" at the front of the classroom. An unforeseen by-product of this was student-initiated peer instruction outside of the classroom. A small case study (approximately 50 students) on the effect of the Hot Seat using the midterm exam showed that students were 9.5 +/- 3.2% more likely to correctly answer a question related to material covered while they occupied the Hot Seat. Analysis of the Astronomy Diagnostic Test revealed that they were twice as likely to learn their Hot Seat material. A survey revealed one likely reason: Students typically spent 15-60 additional minutes preparing for class on their two assigned Hot Seat dates. Curiously, students received no significant benefit (2.2 +/- 3.6%) from their second turn in the Hot Seat, possibly reflecting student immunization to its motivational pressure.

    2017-08-01

    On surveys that assess sensitive personal attributes, indirect questioning aims at increasing respondents' willingness to answer truthfully by protecting confidentiality. However, the assumption that subjects understand questioning procedures fully and trust them to protect their privacy is rarely tested. In a scenario-based design, we compared four indirect questioning procedures in terms of their comprehensibility and perceived privacy protection. All indirect questioning techniques were found to be less comprehensible by respondents than a conventional direct question used for comparison. Less-educated respondents experienced more difficulties when confronted with any indirect questioning technique. Regardless of education, the crosswise model was found to be the most comprehensible among the four indirect methods. Indirect questioning in general was perceived to increase privacy protection in comparison to a direct question. Unexpectedly, comprehension and perceived privacy protection did not correlate. We recommend assessing these factors separately in future evaluations of indirect questioning.

    Full Text Available In multilingual Cameroon, 247 indigenous languages live side by side with English and French (the two official languages and Cameroon Pidgin English (the main lingua franca. While the two official languages of colonial heritage dominate public life in the areas of education, administration, politics, mass media, publicity and literature, both the indigenous languages and Cameroon Pidgin English are relegated to the background. This paper is a critique of language policy in Cameroon revealing that mother tongue education in the early years of primary education remains a distant cry, as the possible introduction of an indigenous language in the school system is not only considered unwanted by educational authorities but equally combated against by parents who believe that the future of their children lies in the mastery of the official languages. This persistent disregard of indigenous languages does not only alienate the Cameroonian child culturally, but further alienates the vast majority of Cameroonians who are illiterate (in English and French since important State business is carried out in the official languages. As regards the implementation of the policy of official language bilingualism, there is clear imbalance in the use of the two official languages as French continues to be the dominant official language while English is relegated to a second place within the State. The frustration that ensues within the Anglophone community has led in recent years to the birth of Anglophone nationalism, a situation that seems to be widening the rift between the two main components of the society (Anglophones and Francophones, thereby compromising national unity. The paper is divided into five major parts. After a brief presentation of the country, the author dwells on multilingualism and language policy since the colonial period. The third, fourth and last parts of the paper focus on the critique of language policy in Cameroon with emphasis first on

    Barsoumian, Alice E; Yun, Heather C

    2018-01-01

    The San Antonio Uniformed Services Health Education Consortium Infectious Disease Fellowship program historically included a monthly short-answer and multiple-choice quiz. The intent was to ensure medical knowledge in relevant content areas that may not be addressed through clinical rotations, such as operationally relevant infectious disease. After completion, it was discussed in a small group with faculty. Over time, faculty noted increasing dissatisfaction with the activity. Spaced interval education is useful in retention of medical knowledge and skills by medical students and residents. Its use in infectious disease fellow education has not been described. To improve the quiz experience, we assessed the introduction of spaced education curriculum in our program. A pre-intervention survey was distributed to assess the monthly quiz with Likert scale and open-ended questions. A multiple-choice question spaced education curriculum was created using the Qstream(R) platform in 2011. Faculty development on question writing was conducted. Two questions were delivered every 2 d. Incorrectly and correctly answered questions were repeated after 7 and 13 d, respectively. Questions needed to be answered correctly twice to be retired. Fellow satisfaction was assessed at semi-annual fellowship reviews over 5 yr and by a one-time repeat survey. Pre-intervention survey of six fellows indicated dissatisfaction with the time commitment of the monthly quiz (median Likert score of 2, mean 6.5 h to complete), neutral in perceived utility, but satisfaction with knowledge retention (Likert score 4). Eighteen fellows over 5 yr participated in the spaced education curriculum. Three quizzes with 20, 39, and 48 questions were designed. Seventeen percentage of questions addressed operationally relevant topics. Fifty-nine percentage of questions were answered correctly on first attempt, improving to 93% correct answer rate at the end of the analysis. Questions were attempted 2,999 times

    The article by Feachem et al, published in the BMJ in 2002, claimed to show that, compared with the United Kingdom (UK) National Health Service (NHS), the Kaiser Permanente healthcare system in the United States (US) has similar healthcare costs per capita, and performance that is considerably better in certain respects. To assess the accuracy of Feachem et al's comparison and conclusions. Detailed re-examination of the data and methods used and consideration of the 82 letters responding to the article. Analyses revealed four main areas in which Feachem et al's methodology was flawed. Firstly, the populations of patients served by Kaiser Permanente and by the NHS are fundamentally different. Kaiser's patients are mainly employed, significantly younger, and significantly less socially deprived and so are healthier. Feachem et al fail to adjust adequately for these factors. Secondly, Feachem et al have wrongly inflated NHS costs by omitting substantial user charges payable by Kaiser members for care, excluding the costs of marketing and administration, and deducting the surplus from Kaiser's costs while underestimating the capital charge element of the NHS budget and other costs. They also used two methods of converting currency, the currency rate and a health purchasing power parity conversion. This is double counting. Feachem et al reported that NHS costs were 10% less per head than Kaiser. Correcting for the double currency conversion gives the NHS a 40% cost advantage such that per capita costs are 1161 dollars and 1951 dollars for the NHS and Kaiser, respectively. Thirdly, Feachem et al use non-standardised data for NHS bed days from the Organisation for Economic Cooperation and Development, rather than official Department of Health bed availability and activity statistics for England. Leaving aside the non-comparability of the population and lack of standardisation of the data, the result is to inflate NHS acute bed use and underestimate the efficiency of

    2011-01-01

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

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

    Highlights: • A new surveying questionnaire for evaluating the security awareness of personnel was developed. • The developed surveying tools consist of four categories and 44 questions in total. • The surveying tools developed in this study can be used in other countries. - Abstract: A survey to evaluate awareness of the nuclear security culture of personnel at nuclear facilities was developed. The survey was made up of a series of questionnaires that were divided into four categories, beliefs and attitude, operating systems, leadership behaviors and staff behaviors. Each category contained six to 16 questions. The category on beliefs and attitude was composed of questions that asked plant workers on how much consideration facility personnel give to issues of security when doing his/her work. The section pertaining to operating systems for nuclear security consisted of questions on guidance documents, information security, and education and training. The questions on leadership behaviors were separated into two parts, one for managers and another for staff. These include questions relating to communication between management and staff, surveillance work related to nuclear security and the sharing of information. The last category of questions concerned staff behaviors. It consisted of questions on knowledge, procedures and implementation related to nuclear security. A survey was conducted on 858 people who worked at nuclear power plants using the questionnaire that was developed in this study. The survey was performed between October 7 to 17, 2014. The survey results were collected and analyzed. A numerical value was given to each question, so that the results of the survey were represented as a score. The data revealed that awareness of the nuclear security culture increased with age. This increase stopped when staff members entered their 50s. It is believed that a person in his/her 50s has a greater degree of experience and passion for their work than

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

    2016-05-01

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

    Full Text Available To Iron or not to Iron: That’s the QuestionGeschiedenis als metgezel [History as a companion] can be read in different ways. An interesting aspect to this book is that it contains a large part of the history of universities and the history of a scientific discipline. We have many official and institutional histories, but those studies reveal only a part of the real life in academia. The merit of the book by Bunna Ebels-Hoving is that it merges official history and personal history. For instance it shows that statistical emancipation of the female scientist does not mean that there is no longer any practical problem. Revealing is the part in the book in which she recounts a discussion with a colleague: should one stop ironing or not. By mixing simple (? household questions with observations about (interdisciplinarity this book shows what – in the words of Max Weber – Wissenschaft als Beruf really means.

    A librarian consultation service was offered to 88 primary care clinicians during office hours. This included a streamlined evidence-based process to answer questions in fewer than 20 min. This included a contact centre accessed through a Web-based platform and using hand-held devices and computers with Web access. Librarians were given technical training in evidence-based medicine, including how to summarise evidence. To describe the process and lessons learned from developing and operating a rapid response librarian consultation service for primary care clinicians. Evaluation included librarian interviews and a clinician exit satisfaction survey. Clinicians were positive about its impact on their clinical practice and decision making. The project revealed some important 'lessons learned' in the clinical use of hand-held devices, knowledge translation and training for clinicians and librarians. The Just-in-Time Librarian Consultation Service showed that it was possible to provide evidence-based answers to clinical questions in 15 min or less. The project overcame a number of barriers using innovative solutions. There are many opportunities to build on this experience for future joint projects of librarians and healthcare providers.

    The neurocognitive profile of community-dwelling Chinese subjects with 'questionable' dementia was studied. One hundred and fifty-four ambulatory Chinese subjects were recruited from local social centers for the elderly. Each subject was examined using the Clinical Dementia Rating (CDR), the Cantonese version of the Mini-Mental State Examination (CMMSE), the Chinese version of the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), the Category Verbal Fluency Test (CVFT), digit and visual span tests, and the Cambridge Neurological Inventory. The neurocognitive profile of nondemented subjects (CDR 0) was compared with that of subjects with 'questionable' dementia (CDR 0.5). Subjects with 'questionable' dementia were older, and had lower educational levels and global cognitive assessment scores than the controls (CMMSE and ADAS-Cog; t tests, p < 0.001). In addition, they also had significantly lower scores in delayed recall, reverse span, verbal fluency tests and worse performance in complex motor tasks related to executive function (Mann-Whitney tests, p < 0.001). Logistic regression analysis revealed that ADAS-Cog, CVFT, and reverse visual span were significant predictors for the CDR of 'questionable' dementia. Aside from memory impairment, executive function deficits were also present in subjects with 'questionable' dementia. To identify groups cognitively at risk for dementia, concomitant assessments of memory and executive function are suggested.

  1. Aphasia centers in North America: a survey.

    Science.gov (United States)

    Simmons-Mackie, Nina; Holland, Audrey L

    2011-08-01

    There is a growing trend toward dedicated programs designed to improve the lives of people with aphasia and their families. We are referring to these programs collectively as "aphasia centers." These programs purportedly differ from more traditional medically based aphasia rehabilitation. However, there is no directory of aphasia centers and no definition of what constitutes such a program. Therefore, an online survey was designed to identify and describe aphasia centers in the United States and Canada. A 37-question survey was posted online via SurveyMonkey. An introductory letter was distributed by electronic mail to a listserv and mailing lists of programs associated with aphasia. Potential respondents who considered themselves an aphasia center were asked to complete the survey. A total of 33 survey responses were analyzed, and descriptive data were compiled resulting in a description of the following aspects of aphasia centers: demographic information, mission, admission and discharge policies, assessment practices, program logistics, staffing patterns, marketing, funding, and services offered. In addition, a qualitative analysis of written text responses revealed the following key themes that appear to characterize the responding programs: services that differ from traditional aphasia rehabilitation; a sense of community; a holistic focus on quality of life, psychosocial well-being, participation, and social support; the centrality of group interaction; and variety/intensity of services. © Thieme Medical Publishers.

  18. Will Veterans Answer Sexual Orientation and Gender Identity Questions?

    Science.gov (United States)

    Ruben, Mollie A; Blosnich, John R; Dichter, Melissa E; Luscri, Lorry; Shipherd, Jillian C

    2017-09-01

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

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.

Short Form 36 (SF-36) Physical Health Component Score and Mental Health Component Score (MCS) surveys as well has CDC (Centers for Disease Control) HRQoL-14 surveys were completed by 37 qualified patients. Mean SF-36 PCS and MCS, normalized at 50, were 37.4 and 44.2, respectively. Eighty percent of participants reported activity/functional limitations secondary to impairments or health problems. Patients reported using medical cannabis to treat a wide array of symptoms across multiple body systems with relief ratings consistently in the 7-10/10 range. The HRQoL results in this sample of medical cannabis-using patients are comparable with published norms in other chronically ill populations. Data presented provide insight into medical cannabis-using patients' self-rated health, HRQoL, disease incidences, and cannabis-related symptom relief.

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

    2018-02-01

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

  18. Collaboration challenges in systematic reviews: a survey of health sciences librarians

    Directory of Open Access Journals (Sweden)

    Joey Nicholson

    2017-10-01

    Results: Of the 17 challenges listed in the survey, 8 were reported as common by over 40% of respondents. These included methodological issues around having too broad or narrow research questions, lacking eligibility criteria, having unclear research questions, and not following established methods. The remaining challenges were interpersonal, including issues around student-led projects and the size of the research team. Of the top 8 most frequent challenges, 5 were also ranked as most difficult to handle. Open-ended responses underscored many of the challenges included in the survey and revealed several additional challenges. Conclusions: These results suggest that the most frequent and challenging issues relate to development of the research question and general communication with team members. Clear protocols for collaboration on systematic reviews, as well as a culture of mentorship, can help librarians prevent and address these challenges.  This article has been approved for the Medical Library Association’s Independent Reading Program.

    Safety pharmacology is a growing discipline with scientists broadly distributed across international geographical regions. This electronic salary survey is the first to be distributed amongst the entire Safety Pharmacology Society (SPS) membership. An electronic survey was sent to all members of the Society. Categorical survey questions assessed membership employment types, annual incomes, and professional certifications, along with other associated career attributes. This survey was distributed to the SPS membership that is comprised of safety pharmacologists, toxicologists and pharmacologists working globally in the pharmaceutical industry, at contract research organizations (CRO), regulatory agencies, and academia or within the technology provider industry. The survey was open for responses from December 2015 to March 2016. The survey response rate was 28% (129/453). North America (68%) was the region with the largest number of respondents followed by Europe (28%). A preponderance of respondents (77%) had 12years of industry experience or more. 52% of responders earned annually between $40,000 and $120,000. As expected, salary was generally positively correlated with the number of years of experience in the industry or the educational background but there was no correlation between salary and the number of employee's directly supervised. The median salary was higher for male vs female respondents, but so was median age, indicative of no gender 'salary gap'. Our 2016 SPS salary survey results showcased significant diversity regarding factors that can influence salary compensation within this discipline. These data provided insights into the complex global job market trends. They also revealed the level of scientific specialization embedded within the organization, presently uniquely positioned to support the dynamic career paths of current and future safety pharmacologists.

    2017-01-01

    Background: Scientific editors (i.e., those who make decisions on the content and policies of a journal) have a central role in the editorial process at biomedical journals. However, very little is known about the training needs of these editors or what competencies are required to perform effectively in this role. Methods: We conducted a survey of perceptions and training needs among scientific editors from major editorial organizations around the world, followed by a modified Delphi process in which we invited the same scientific editors to rate the importance of competency-related statements obtained from a previous scoping review. Results: A total of 148 participants completed the survey of perceptions and training needs. At least 80% of participants agreed on six of the 38 skill and expertise-related statements presented to them as being important or very important to their role as scientific editors. At least 80% agreed on three of the 38 statements as necessary skills they perceived themselves as possessing (well or very well).  The top five items on participants' list of top training needs were training in statistics, research methods, publication ethics, recruiting and dealing with peer reviewers, and indexing of journals. The three rounds of the Delphi were completed by 83, 83, and 73 participants, respectively, which ultimately produced a list of 23 "highly rated" competency-related statements and another 86 "included" items. Conclusion: Both the survey and the modified Delphi process will be critical for understanding knowledge and training gaps among scientific editors when designing curriculum around core competencies in the future.

    The purpose of this study was to use a mixed-methods approach to determine the validity and reliability of measurements used within an alcohol-exposed pregnancy prevention program for American Indian women. To develop validity, content experts provided input into the survey measures, and a "think aloud" methodology was conducted with 23 American Indian women. After revising the measurements based on this input, a test-retest was conducted with 79 American Indian women who were randomized to complete either the original measurements or the new, modified measurements. The test-retest revealed that some of the questions performed better for the modified version, whereas others appeared to be more reliable for the original version. The mixed-methods approach was a useful methodology for gathering feedback on survey measurements from American Indian participants and in indicating specific survey questions that needed to be modified for this population. © The Author(s) 2015.

    2011-12-01

    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.

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

  6. Some of the unanswered questions in finance

    Directory of Open Access Journals (Sweden)

    Đurić Dragana M.

    2006-01-01

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

  7. From Question Answering to Visual Exploration

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

    2006-08-11

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

    Full Text Available Question formation and focusing are two transformational processes attested in Standard Yorùbá both of which have been extensively discussed in previous studies. However, very little is known about these concepts in Owo (Owò̩̩̀ a south-East Yoruba (Yorùbá dialect. This study examines the concept of questions and focusing in Owo ̩̩̀̀dialect with a comparison of the processes in Standard Yorùbá. The study revealed some differences as well as similarities in the two processes in Owo ̩̩̀̀and standard Yorùbá. Just like in Standard Yorùbá, question markers in Owo ̩̩̀̀normally occur in sentence initial and final positions. However, the question marker de ̩̀constantly appears sentence medially before and before verbs in certain constructions. Furthermore, while the focus marker in Yorùbá normally occurs immediately after the focused item with a stable form, the focus marker in Owo ̩̩̀̀usually occurs at the sentence final position as a reduplicated form of the last syllable of the final item. Also, a pronoun which indicates number and agreement usually occurs immediately after the focused item in Owò̩̩̀. Finally, just like in Yorùbá, there is a syntactic relationship between question and focusing in Owo ̩̩̀̀dialect.

    Classroom questioning is a common teaching and learning strategy in postgraduate nurse education. Technologies such as audience response systems (ARS) may offer advantage over traditional approaches to classroom questioning. However, despite being available since the 1960s, ARSs are still considered novel in many postgraduate nurse education classroom settings. This article aims to explicate the attitudes of postgraduate nursing students in an Irish academic teaching hospital towards classroom questioning (CQ) and the use of ARSs as an alternative to traditional CQ techniques. The results of this small-scale study demonstrate that ARSs have a role to play in CQ in the postgraduate setting, being regarded by students as beneficial to learning, psychological safety and classroom interaction.

  10. On safety goals and related questions

    International Nuclear Information System (INIS)

    Kaplan, S.

    1985-01-01

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

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

  12. A questions-based investigation of consumer mental-health information

    Kart, Joyce Brothers

    2015-01-01

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

    The responsibilities of the Nuclear Installations Inspectorate are considered, and the responsibilities of other bodies for (a) reprocessing and enrichment, and (b) security. Questions for the Nuclear Installations Inspectorate are then set out under the following heads: general (on such topics as vandalism, sabotage, threats, security, reactor incidents); magnox reactors; corrosion; advanced gas-cooled reactor; steam generating heavy water reactor; fast breeder reactor; reproces-sing and waste. Most of the questions are concerned with technical problems that have been reported or might possibly arise during construction or operation, affecting the safety of the reactor or process. (U.K.)

    The subject area referred to as 'wave chaos', 'quantum chaos' or 'quantum chaology' has been investigated mostly by the theoretical physics community in the last 30 years. The questions it raises have more recently also attracted the attention of mathematicians and mathematical physicists, due to connections with number theory, graph theory, Riemannian, hyperbolic or complex geometry, classical dynamical systems, probability, etc. After giving a rough account on 'what is quantum chaos?', I intend to list some pending questions, some of them having been raised a long time ago, some others more recent. The choice of problems (and of references) is of course partial and personal. (open problem)

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

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

    Adams, Nancy E

    2015-01-01

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

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

  2. Two questions about surrogacy and exploitation.

    Science.gov (United States)

    Wertheimer, Alan

    1992-01-01

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

  16. The Priority of the Question: Focus Questions for Sustained Reasoning in Science

    Science.gov (United States)

    Lustick, David

    2010-08-01

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

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

Bringing out a monthly journal is a lonely business. Issue after issue goes out, and the only response is when there's an occasional factual error. Send out a readership survey and a faint echo comes back. Most striking was the sheer enthusiasm of the replies. Despite the current erosion of support in the US (see page 2), subatomic physics has significant world-wide box-office appeal. Most important was to find out who our readers are. 61% of the replies came from Europe, 21% from the USA, 14% from elsewhere, (including the former Soviet Union), and 4% from inside CERN. Not surprisingly, the main audience (37%) is in the high energy physics sector. Then comes teaching (31%), followed closely by accelerators operations and design (12%) and industry (11%). Apart from detailed breakdowns of readership and feedback on the journal's content and style, the replies revealed several major features. Firstly, the CERN Courier is widely read and appreciated. There are a lot of people outside the immediate research field who want to keep broadly up to date with the latest developments in high energy physics and related fields, without getting too involved in details. It was gratifying to receive replies from far-flung places (Nepal, Indonesia,....), and learn how much distant readers appreciate getting such regular information. 'It helps us feel part of the world scene,' was a typical such reply, from Australia. Despite jet airplanes, fax and electronic mail, our planet is still big.

    Parker, Joyce M; Anderson, Charles W; Heidemann, Merle; Merrill, John; Merritt, Brett; Richmond, Gail; Urban-Lurain, Mark

    2012-01-01

    We present a diagnostic question cluster (DQC) that assesses undergraduates' thinking about photosynthesis. This assessment tool is not designed to identify individual misconceptions. Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific principles: conservation of matter, conservation of energy, and the hierarchical nature of biological systems. Data on students' responses to the cluster items and uses of some of the questions in multiple-choice, multiple-true/false, and essay formats are compared. A cross-over study indicates that the multiple-true/false format shows promise as a machine-gradable format that identifies students who have a mixture of accurate and inaccurate ideas. In addition, interviews with students about their choices on three multiple-choice questions reveal the fragility of students' understanding. Collectively, the data show that many undergraduates lack both a basic understanding of the role of photosynthesis in plant metabolism and the ability to reason with scientific principles when learning new content. Implications for instruction are discussed.

    2017-12-01

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

    Early diagnosis of food allergies (FA) is important for a favorable prognosis. This study aimed to determine the level of awareness of FA among pediatricians in Kuwait. A 43-item self-administered questionnaire was designed and distributed to pediatricians working at 4 government hospitals in Kuwait. A total of 140 pediatricians completed the questionnaire, with a participation rate of 51.1% (81 males and 59 females). The mean age of participants was 40.81 years, and the mean number of years working in pediatrics was 13.94 years. The mean overall knowledge score was 22.2. The pediatricians' overall knowledge scores were found to be significantly associated with their age (older pediatricians had higher overall scores) and years of experience as a pediatrician but were independent from hospital site, gender, or rank. A multiple linear regression revealed pediatrician age and gender were the only variables that were significantly associated with the overall knowledge score. Only 16.4% of the participants answered at least 2/3 of the survey questions correctly. The questions that were correctly answered by ≤ 2/3 of the participants constituted 80% of clinical presentation questions, 66.6% of diagnostics questions, 77.7% of treatment questions, and 42.8% of prevention questions. Interestingly, among 68 pediatricians (48.5%) who determined that they felt comfortable evaluating and treating patients with FA, only 12 (17.6%) passed the questionnaire. This survey demonstrates that there is a noteworthy deficiency of pediatricians' awareness about FA. The implementation of strategies to improve pediatricians' awareness is critical to diagnose food allergy patients early and improve their health and outcomes.

    This paper refracts a comparison of three distinct transcription styles through questions of researcher reflexivity. It uses the data from a single question asked by the researcher in multiple interviews for a small empirical project. These data are transcribed in three ways, and the resulting transcripts are discussed in relation to the analysis…

  10. Using Pre-Assessment and In-Class Questions to Change Student Understanding of Molecular Movements

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

    This survey serves as the ninth in a series of toxicology salary surveys conducted at 3-year intervals and beginning in 1988. An electronic survey instrument was distributed to 5919 individuals including members of the Society of Toxicology, American College of Toxicology, and 23 additional professional organizations. Question items inquired about gender, age, degree, years of experience, certifications held, areas of specialization, society membership, employment and income. Overall, 1293 responses were received (response rate 21.8%). The results of the 2014 survey provide insight into the job market and career path for current and future toxicologists. © The Author(s) 2016.

    Successful health information technology (HIT) implementations need to be informed on the context of use and on users' attitudes. To this end, we developed the CLinical Computer Systems Survey (CLICS) instrument. CLICS reflects a socio-technical view of HIT adoption, and is designed to encompass all members of the clinical team. We used the survey in a large English hospital as part of its internal evaluation of the implementation of an electronic patient record system (EPR). The survey revealed extent and type of use of the EPR; how it related to and integrated with other existing systems; and people's views on its use, usability and emergent safety issues. Significantly, participants really appreciated 'being asked'. They also reminded us of the wider range of administrative roles engaged with EPR. This observation reveals pertinent questions as to our understanding of the boundaries between administrative tasks and clinical medicine - what we propose as the field of 'administrative medicine'.

  13. Regulatory and licensee surveys

    International Nuclear Information System (INIS)

    2009-01-01

    Prior to the workshop two CSNI/WGHOF surveys were distributed. One survey was directed at regulatory bodies and the other was directed at plant licensees. The surveys were: 1 - Regulatory Expectations of Licensees' Arrangements to Ensure Suitable Organisational Structure, Resources and Competencies to Manage Safety (sent to WGHOF regulatory members). The survey requested that the respondents provide a brief overview of the situation related to plant organisations in their country, their regulatory expectations and their formal requirements. The survey addressed three subjects: the demonstration and documentation of organisational structures, resources and competencies, organisational changes, issues for improvement (for both current and new plants). Responses were received from eleven regulatory bodies. 2 - Approaches to Justify Organisational Suitability (sent to selected licensees). The purpose of the survey to was to gain an understanding of how licensees ensure organisational suitability, resources and competencies. This information was used to assist in the development of the issues and subjects that were addressed at the group discussion sessions. Responses were received from over fifteen licensees from nine countries. The survey requested that the licensees provide information on how they ensure effective organisational structures at their plants. The survey grouped the questions into the following four categories: organisational safety functions, resource and competence, decision-making and communication, good examples and improvement needs. The findings from these surveys were used in conjunction with other factors to identify the key issues for the workshop discussion sessions. The responses from these two surveys are discussed briefly in Sections 4 and 5 of this report. More extensive reviews of the regulatory and licensee responses are provided in Appendix 1

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

    Seth, K.

    1994-01-01

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

  16. Aging and depression: some unanswered questions.

    Jarvik, L F

    1976-05-01

    The subject of aging and depression leaves many unanswered questions, and the lack of precise and universally accepted definitions (not to mention an inadequate nosology) further complicates the issue. Little is known regarding the differentiation of depressive illness from a melancholic response to the stressful aging process, and equally little regarding the natural history of depressions with onset in the teens, 20s, or 30s. Studies are focusing on biochemical and physiological aspects of depression, but at present biochemists suffer from the uncertainties of the clinicians, and the clinicians and geneticists from the limitations of the biochemists. However, despite our uncertainties about the condition, several effective forms of therapy have been developed, ranging from a focus on the therapeutic milieu to the use of pharmacologic antidepressants (particularly lithium). Ultimately, the question remains: Why are not all elderly persons suffering from depression? The answer may lie in the interaction of environment, life stresses, and the internal adaptive capacities of the individual.

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

    Almost three decades of genetic and molecular analyses have resulted in detailed insights into many of the processes that take place during flower development and in the identification of a large number of key regulatory genes that control these processes. Despite this impressive progress, many questions about how flower development is controlled in different angiosperm species remain unanswered. In this chapter, we discuss some of these open questions and the experimental strategies with which they could be addressed. Specifically, we focus on the areas of floral meristem development and patterning, floral organ specification and differentiation, as well as on the molecular mechanisms underlying the evolutionary changes that have led to the astounding variations in flower size and architecture among extant and extinct angiosperms.

    Full Text Available Aims Using the best assessment methods is an important factor in educational development of health students. Modified essay questions and multiple choice questions are two prevalent methods of assessing the students. The aim of this study was to compare two methods of modified essay questions and multiple choice questions in occupational health engineering and work laws courses. Materials & Methods This semi-experimental study was performed during 2013 to 2014 on occupational health students of Mashhad University of Medical Sciences. The class of occupational health and work laws course in 2013 was considered as group A and the class of 2014 as group B. Each group had 50 students.The group A students were assessed by modified essay questions method and the group B by multiple choice questions method.Data were analyzed in SPSS 16 software by paired T test and odd’s ratio. Findings The mean grade of occupational health and work laws course was 18.68±0.91 in group A (modified essay questions and was 18.78±0.86 in group B (multiple choice questions which was not significantly different (t=-0.41; p=0.684. The mean grade of chemical chapter (p<0.001 in occupational health engineering and harmful work law (p<0.001 and other (p=0.015 chapters in work laws were significantly different between two groups. Conclusion Modified essay questions and multiple choice questions methods have nearly the same student assessing value for the occupational health engineering and work laws course.

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

However, in the last period of his researches, Husserl addressed repeatedly the issue, in the context of a transcendental-phenomenological analysis of the constitution of the human world. Husserl’s phenomenology proofs itself to be a non-ideological way to enquire about man and animal, rethinking their differences and their continuity, by moving from the experience of life and world.

    In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in supersymmetric and string phenomenology. We describe each within the context of string constructions, illustrating them with specific examples where applicable. Each topic culminates in a set of questions that we believe are amenable to direct consideration by string theorists, and whose answers we think could help connect string theory and phenomenology.

    The principal question for the world's oil industry is how to replace today's and tomorrow's consumption of oil with new reserves. This is very important for the oil companies. Reduced reserves mean reduced values, which immediately has an impact on the balance sheet and the share price. The next ten years the world will consume over 300 billion barrels of oil and it may appear very difficult to replace this with new reserves

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

    As the preparation of salads involves extensive handling and the use of uncooked ingredients, they are particularly vulnerable to microbial contamination. This study aimed to determine the microbial safety and quality of pre-packed salads and salad bar ingredients sold in Singapore, so as to identify public health risks that could arise from consuming salads and to determine areas for improvement in the management of food safety. The most frequently encountered organism in pre-packed salad samples was B. cereus, particularly in pasta salads (33.3%, 10/30). The most commonly detected organism in salad bar ingredients was L. monocytogenes, in particular seafood ingredients (44.1%, 15/34), largely due to contaminated smoked salmon. Further investigation showed that 21.6% (37/171) of the pre-packed smoked salmon sold in supermarkets contained L. monocytogenes. Significantly higher prevalence of L. monocytogenes and higher Standard Plate Count were detected in smoked salmon at salad bars compared to pre-packed smoked salmon in supermarkets, which suggested multiplication of the organism as the products move down the supply chain. Further molecular analysis revealed that L. monocytogenes Sequence Type (ST) 2 and ST87 were present in a particular brand of pre-packed salmon products over a 4-year period, implying a potential persistent contamination problem at the manufacturing level. Our findings highlighted a need to improve manufacturing and retail hygiene processes as well as to educate vulnerable populations to avoid consuming food prone to L. monocytogenes contamination.

    Full Text Available In Ms/her practice, a pediatrician frequently faces ambiguous questions about foods for infants during the first year of life in particular. Not only parents ask pediatricians these questions - the latter naturally arise during work and attempts to pinpoint the problem of adequate nutrition during infancy. These questions are whether complementary foods containing starch cause allergy in an infant; gluten is a detrimental ingredient of infant foods; hydrolysis of cereal polysaccharides is essential; palm oil is dangerous to an infant's health; butter fat as an ingredient infant foods may be harmful to a child. Among other things, butter fat in globules is shown to contain phospholipids, gangliosides, cholesterol, which are essential for a child's development and absent in infant formulas. In this connection, addition of fat globule membranes to foods is promising in terms of the provision of an infant with lipids of full value. There is a need for further in-depth investigations of infant feeding practices, by keeping in mind numerous features of an infant's organism.

    During the 7th legislative period (1972/76) of the German Bundestag the Federal Government has repeatedly commented on questions concerning nuclear energy. The present documentation comprises a selection of the most important issues. The collection contains in particular: written and oral answers of the Federal Government to written or oral questions of members of parliament; answers of the Federal Government to major and minor interpellations of fractions or factions; statements of the chancellor, the ministers and permanent secretaries; bills of the Federal Government if they were issued as parliamentary documents or as plenary minutes. The main attention when selecting the documents was drawn to giving complete recording of the statements on the safety of nuclear plants and on radiation protection. Furthermore, the comments on questions concerning nuclear energy were considered both in general and in connection with alternative energy sources. Eventually, the general situation concerning energy could be verified. The selection of documents has certainly not thoroughly remained uninfluenced by subjective decisions. The parliamentary documents and plenary minutes given here are recorded by chronological order. An index of subject headings will facilitate access to all documents. (orig.) 891 HP [de

    Full Text Available WHO recommends a male circumcision (MC prevalence rate higher than 80% to have a substantial impact on the HIV-AIDS epidemic in Eastern and Southern Africa. Orange Farm, a township in South Africa, has a free-for-service voluntary medical male circumcision (VMMC clinic in operation since 2008. Following an intense campaign from 2008 to 2010, MC prevalence rate increased to 55.4% (ANRS-12126. Ongoing and past VMMC campaigns focused on youths, through school talks, and adults at a community level. The main objective of the study was to assess the change in MC prevalence rate among adults aged 18-19 and 18-49 years in the past 5 years.A cross-sectional survey (ANRS-12285 was conducted among a random sample of 522 adult men in 2015. MC status and characteristics of participants were collected through a genital examination and a face-to-face questionnaire.MC prevalence rate among young adult men aged 18-19 years increased markedly from 61.2% (95%CI: 57.4% to 65.0% in 2010 to 87.5% (76.0% to 94.6% in 2015 (p<0.001. In the same period, among men aged 18-49 years, MC prevalence rate varied slightly from 55.4% (53.6% to 57.1% to 56.7% (52.4% to 60.9%. In 2015, 84.9% (79.2% to 89.5% of uncircumcised adult men reported that they were willing to be circumcised. However, we estimated that only 4.6% (11/237; 2.5% to 7.9% of the uncircumcised men underwent circumcision in 2015, despite 117/185 (63.2%; 95%CI: 56.1% to 69.9% who reported that they were definitely willing to become circumcised.In Orange Farm, VMMC campaigns were successful among the youth and led to a sufficiently high MC prevalence rate to have a substantial impact in the future on the HIV-AIDS epidemic. However, despite high acceptability and a free VMMC service, VMMC campaigns since 2010 have failed to increase MC prevalence rate among adults to above 80%. These campaigns should be revisited.

  15. Five questions to ask about the soils

    I think that anyone who ever gave a lecture would agree that this feels like being on a stage. One has to educate the audience of course, but also keep attention and be interesting to the listeners. Authority is important but there is a certain vulnerability at all times. There is also a fine line on both sides that should not be crossed. However, the most important thing is that the audience remembers the lecture and certain points the lecturer made for at least some time, and even more that someone gets interested enough to ask for more details. This is often done by giving interesting examples and unusual comparison. Teaching a soils course there are five main questions to be addressed, of which first four are often subordinated to the fifth being the most complex. First question is "Is the soil alive?". The answer is yes, and that is what it differentiates from any type of sediment or rock, and it is very vulnerable to environmental change. The second question is "Where does it come from?" Rocks being a main origin of soils are often neglected in soil science and petrography in general, and weathering, as an important process for soil formation, are not given enough explaining. Petrography teaches us about rock characteristics, structure and texture and mineralogy. Understanding petrography would help in understanding the weathering processes which are crucial for soil formation and this must not be ignored. The third question is "Is it old?" Yes, it is - at least for everybody else except geologists. It is important to understand how slow the soil formation process is. The forth question is "Does it move?" Yes, it can move and the faster it moves downhill, it less likes it. Erosion is a very important problem for soil and must be addressed. And finally, the fifth question is "What are the main characteristics of soils?" This is an opportunity to talk about physical, chemical, biological, microbiological issues. As the most elaborate question it allows the

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

    The Fukushima catastrophe of March 11, 2011 has called into question the share of nuclear energy in France and in foreign countries. Its replacement by renewable energy sources and the safety of nuclear power plants are in the center of today's debates. But what is the reality behind the mass of contradictory information that exists on this complex topic? This book moves the question out of the media noise and supplies objective and factual information with reliable figures about the nuclear industry by answering 30 key-questions. (J.S.)

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

    1980-01-01

    The theme of the lecture is the place of the fast reactor in an evolving nuclear programme. The whole question of plutonium is first considered, ie its method of production and the ways in which it can be used in the fast reactor fuel cycle. Whether fast reactors are necessary is then discussed. Their safety is examined with particular attention to those design features which are most criticised ie high volumetric power density of the core, and the use of liquid sodium as coolant. Attention is then paid to environmental and safeguard aspects. (U.K.)

    Baroque architect and mathematician Guarino Guarini is the subject of this issue of the Nexus Network Journal. A group of international scholars were invited to contribute papers that shed light on the unanswered questions in several areas: Baroque architecture in general and Guarini’s architecture in particular; philosophy; history of structural mechanics; mathematics and history of mathematics, cosmology. As always, the NNJ takes an interdisciplinary approach to the broad range of subjects that Guarini concerned himself with, thus the final results will add significantly to our understanding of how Guarini’s actual practical and technical processes were informed by knowledge of his multifaceted scientific and philosophical interests.

    The essay deals with questions of profitability in connection with the use of solar energy to heat buildings or to prepare hot water. The total problem is approached from 3 points of view: 1. General national economy point of view: Judgment by politicians determines the possibilities of support by the government. 2. The business economy aspect: Here the most important matter is to construct the plants with dimensions permitting to obtain the highest profits possible. 3. The financing model: possible incentives must be taken into consideration as well as technical aspects, e.g. the service life of the plants.

    The long history of the study of quantum gravity has thrown up a complex web of ideas and approaches. The aim of this article is to unravel this web a little by analysing some of the {\\em prima facie\\/} questions that can be asked of almost any approach to quantum gravity and whose answers assist in classifying the different schemes. Particular emphasis is placed on (i) the role of background conceptual and technical structure; (ii) the role of spacetime diffeomorphisms; and (iii) the problem of time.

    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.

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

    2013-09-01

    It is commonly thought that natural selection explains the rise of adaptive complexity. Razeto-Barry and Frick (2011) have recently argued in favour of this view, dubbing it the Creative View. I argue that the Creative View is mistaken if it claims that natural selection serves to answer Paley's question. This is shown by a case that brings out the contrastive structure inherent in this demand for explanation. There is, however, a rather trivial sense in which specific environmental conditions are crucial for the rise of specific adaptations, but this is hardly what opponents of the Creative View are denying.

    Science.gov (United States)

    Knuth,Kevin H.

    2005-01-01

    For over a century, the study of logic has focused on the algebra of logical statements. This work, first performed by George Boole, has led to the development of modern computers, and was shown by Richard T. Cox to be the foundation of Bayesian inference. Meanwhile the logic of questions has been much neglected. For our computing machines to be truly intelligent, they need to be able to ask relevant questions. In this paper I will show how the Boolean lattice of logical statements gives rise to the free distributive lattice of questions thus defining their algebra. Furthermore, there exists a quantity analogous to probability, called relevance, which quantifies the degree to which one question answers another. I will show that relevance is not only a natural generalization of information theory, but also forms its foundation.

    2011-10-01

    The survey method is often used to identify trends in sexual behaviour and attitudes. In order for research conclusions to be valid, however, data gathered from surveys must be unambiguous. For the current paper we reviewed survey research of sexual behaviour published in recent years. Our objective was to identify common methodological issues and provide recommendations for how to address them. We examined 62 articles, published in four prominent sexual health journals over the past six years. We evaluated each article based on how adequately its authors addressed four recurring methodological issues: ambiguous terminology, heterosexual bias, procedures that compromise honesty in responses, and survey language/literacy considerations. The review revealed some recurring issues: 47% of the studies failed to address the question of sexual orientation, sexual behaviour terminology was explicitly defined in only 32% of questionnaires, fewer than 5% of surveys clarified whether the sexual encounters in question were consensual, and 21% of the articles contained no mention of anonymity or confidentiality for participants. These results reveal common issues with survey data that compromise the validity of findings. In order to have confidence in research conclusions and recommendations, it is important that these issues be addressed.

  20. [Psychiatric assessment in civil law questions].

    Science.gov (United States)

    Nedopil, N

    2009-05-01

    Psychiatric reports in German civil law cases are required if questions are raised of legal capacity, capacity to express a testamentary will, ability to sue or be sued, capacity to marry, ability of mentally disordered patients to consent to treatment, and when custody or hospital orders of these patients is considered or compensation is due for mental disorders resulting from accidents. Many reports must decide whether the ability to decide using sound reason or motives is or was impaired by a mental disorder. This capability is attributed to every adult person; only if incapability is claimed must it be proven by psychiatric assessment. As in most psychiatric court reports, such assessments must be structured in several steps. First a clinical diagnosis has to be established which must then be translated into legal terminology. After this has been accomplished, the psychiatrist must describe the functional impairments caused by the disorder and define the probability with which these impairments might affect the legal act in question. Most reports are prepared in the context of custody law, which centers on helping those patients who, due to a mental disorder, cannot manage their own legal matters.

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

    1979-01-01

    The author, a psycho-sociologist and a professor in the department of sociology at l'Université de Montreal, looks back and reflects on his practice as an intervener in different types of groups. He returns to his first experiences with T-groups and to the analysis of them which he made at the beginning of his practice. Furthermore, this analysis touches on questions that remain very relevant. Thus the author explains why, for social reasons, he came to privilege work with "real groups" rather than that with spontaneous groups. On the basis of twenty years of experience and a view of many group approaches it can be asked whether the question of man in society as a change agent should not be posed to a greater extent within groups. 1) Dans Sociologie A Sociétés, vol. 9, no 2, d'octobre 1977, le lecteur trouvera un article de moi qui préserve une réflexion plus systématique mais sans référence immédiate à ma propre pratique.

The influence of the social networks like instrument of communication is not exempt from risks for the quantity of information that is facilitated and is shared. The lack of a specific regulation that he contemplates from the point of view of the Law which is the protection that a minor must have, does that there take place situations of abandonment of the rights of the same ones.The opportunity of regulation has been left to escape in the future law of protection of the infancy, nowadays in phase of preliminary design, since it does not refer to the social networks since it had been desirable. The current procedure as for minors, as well as those of protection of information, between others, do not turn out to be sufficient to contemplate all the situations of risk that can be given in the above mentioned area. In the present work we propose to think on minors and social networks raising some legal questions, and trying to contribute some response to the problematics that appears in the juridical area.

  4. Supply chain design: Some critical questions

    Directory of Open Access Journals (Sweden)

    J. D. Nel

    2010-11-01

    Full Text Available Effective supply chain management (SCM requires organisations to work together in order to satisfy the needs of their end customers. Since organisations have to determine which processes and relationships will best achieve this aim, the design of their supply chains is important. Supply chain design thus forms an integral part of SCM and embodies the supply chain's structure. Unfortunately, too many organisations allow the design of their supply chain to evolve into its current form instead of planning their supply chain design (SCD efforts. The literature is vague on what SCD efforts constitute. This article consists of a comprehensive literature study in which an effort was made to bring more clarity on exactly what purposeful SCD efforts consist of, and some key questions were formulated that organisations could use as a guide in their SCD practices. From these critical questions a conceptual framework has been developed that can be used to determine whether organisations' SCD practices are aligned with organisational objectives. The conceptual framework was tested at two South African organisations to determine if it indeed can be be used to analyse the SCD practices of organisations.

    Nicholson, Joey; McCrillis, Aileen; Williams, Jeff D

    2017-10-01

    While many librarians have been asked to participate in systematic reviews with researchers, often these researchers are not familiar with the systematic review process or the appropriate role for librarians. The purpose of this study was to identify the challenges and barriers that librarians face when collaborating on systematic reviews. To take a wider view of the whole process of collaborating on systematic reviews, the authors deliberately focused on interpersonal and methodological issues other than searching itself. To characterize the biggest challenges that librarians face while collaborating on systematic review projects, we used a web-based survey. The thirteen-item survey included seventeen challenges grouped into two categories: methodological and interpersonal. Participants were required to indicate the frequency and difficulty of the challenges listed. Open-ended questions allowed survey participants to describe challenges not listed in the survey and to describe strategies used to overcome challenges. Of the 17 challenges listed in the survey, 8 were reported as common by over 40% of respondents. These included methodological issues around having too broad or narrow research questions, lacking eligibility criteria, having unclear research questions, and not following established methods. The remaining challenges were interpersonal, including issues around student-led projects and the size of the research team. Of the top 8 most frequent challenges, 5 were also ranked as most difficult to handle. Open-ended responses underscored many of the challenges included in the survey and revealed several additional challenges. These results suggest that the most frequent and challenging issues relate to development of the research question and general communication with team members. Clear protocols for collaboration on systematic reviews, as well as a culture of mentorship, can help librarians prevent and address these challenges.

    A new experimentally feasible anonymous survey protocol with authentication using Greenberger-Horne-Zeilinger (GHZ) entangled states is proposed. In this protocol, a chief executive officer (CEO) of a firm or company is trying to find out the effect of a possible action. In order to prepare a fair voting, the CEO would like to make an anonymous survey and is also interested in the total action for the whole company and he doesn't want to have a partial estimate for each department. In our proposal, there are two voters, Alice and Bob, voting on a question with a response of either "yes" or "no" and a tallyman, whose responsibility is to determine whether they have cast the same vote or not. In the proposed protocol the total response of the voters is calculated without revealing the actual votes of the voters.

    The sequence used for collecting quantitative and qualitative data in concurrent mixed-methods research may influence participants' responses. Empirical evidence is needed to determine if the order of data collection in concurrent mixed methods research biases participants' responses to closed and open-ended questions. To examine the influence of the quantitative-qualitative sequence on responses to closed and open-ended questions when assessing the same variables or aspects of a phenomenon simultaneously within the same study phase. A descriptive cross-sectional, concurrent mixed-methods design was used to collect quantitative (survey) and qualitative (interview) data. The setting was a large multi-site health care centre in Canada. A convenience sample of 50 registered nurses was selected and participated in the study. Participants were randomly assigned to one of two sequences for data collection, quantitative-qualitative or qualitative-quantitative. Independent t-tests were performed to compare the two groups' responses to the survey items. Directed content analysis was used to compare the participants' responses to the interview questions. The sequence of data collection did not greatly affect the participants' responses to the closed-ended questions (survey items) or the open-ended questions (interview questions). The sequencing of data collection, when using both survey and semi-structured interviews, may not bias participants' responses to closed or open-ended questions. Additional research is required to confirm these findings. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Classroom response systems are widely used in interactive teaching environments as a way to engage students by asking them questions. Previous research on the time taken by students to respond to conceptual questions has yielded insights on how students think and change conceptions. We measure the amount of time students take to respond to in-class, conceptual questions [ConcepTests (CTs] in two introductory physics courses taught using Peer Instruction and use item response theory to determine the difficulty of the CTs. We examine response time differences between correct and incorrect answers both before and after the peer discussion for CTs of varying difficulty. We also determine the relationship between response time and student performance on a standardized test of incoming physics knowledge, precourse self-efficacy, and gender. Our data reveal three results of interest. First, response time for correct answers is significantly faster than for incorrect answers, both before and after peer discussion, especially for easy CTs. Second, students with greater incoming physics knowledge and higher self-efficacy respond faster in both rounds. Third, there is no gender difference in response rate after controlling for incoming physics knowledge scores, although males register significantly more attempts before committing to a final answer than do female students. These results provide insight into effective CT pacing during Peer Instruction. In particular, in order to maintain a pace that keeps everyone engaged, students should not be given too much time to respond. When around 80% of the answers are in, the ratio of correct to incorrect responses rapidly approaches levels indicating random guessing and instructors should close the poll.

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

    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.

In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring. Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all thi...

    Full Text Available Background. We investigated the validity of the two hyperacusis items of the TSCHQ (Tinnitus Sample Case History Questionnaire from the TRI (Tinnitus Research Initiative database by comparing them with the German hyperacusis questionnaire GÜF. Methods. We investigated the association of the GÜF with the TSCHQ screening questions for both the sum score and the single items with correlation, contrast, principal component, and discriminant analysis in a sample of 161 patients with chronic tinnitus. Results. TSCHQ items and the GÜF total score were significantly associated with a special focus on fear and pain related hyperacusis. Factor analysis of the GÜF revealed the three factors “fear and pain related hyperacusis,” “hearing related problems,” and “problems in quality of life.” A discriminant analysis showed a sensitivity of 64% and a specificity of 71% of the TSCHQ items for the establishment of tinnitus patient subgroups with and without hyperacusis. Discussion. Both hyperacusis TSCHQ items can serve as screening questions with respect to self-reported hyperacusis in chronic tinnitus with a specific focus on fear and pain related hyperacusis. However, the multiple dimensions of hyperacusis should be considered for diagnosis and treatment in both scientific and clinical contexts.

    This article reports on the launch of the Schlumberger's Q-Marine approach to seismic imaging and the almost simultaneous establishment of Western Geco from the merged Western Geophysical and Schlumberger's Geco-Prakla, and examines the effects of these activities on the seismic data acquisition market. Details are given of the ability to carry out repeated 3-dimensional seismic surveys over a reservoir during production using conventional streamer acquisition allowing in effect 4-dimensional reservoir monitoring. The on-board computer processing systems, the streamer steering system, and the collection of accurate high resolution data are discussed

  17. Oceanic hydrates: more questions than answers

    International Nuclear Information System (INIS)

    Laherrere, Jean

    2000-01-01

    Methane hydrates create problems by blocking pipelines and casing; they are also accused of contributing to environmental problems (e.g. global warming). Methane hydrates are also found in permafrost areas and in oceanic sediments where the necessary temperature and pressure for stability occur. Claims for the widespread occurrence in thick oceanic deposits are unfounded: apparently indirect evidence from seismic reflectors, seismic hydrocarbon indicators, logs and free samples is unreliable. At one time, hydrate was seen as a static, biogenic, continuous, huge resource but that view is changing to one of a dynamic, overpressurised, discontinuous and unreliable resource. Only Japan and India are currently showing any serious interest in hydrates. Academic research has raised more questions than answers. It is suggested that more hard exploratory evidence rather than theoretical study is required

  18. Questions of Modern Cosmology Galileo's Legacy

    2009-01-01

    Are we living in the "golden age" of cosmology? Are we close to understanding the nature of the unknown ingredients of the currently most accepted cosmological model and the physics of the early Universe? Or are we instead approaching a paradigm shift? What is dark matter and does it exist? How is it distributed around galaxies and clusters? Is the scientific community open to alternative ideas that may prompt a new scientific revolution - as the Copernican revolution did in Galileo's time? Do other types of supernovae exist that can be of interest for cosmology? Why have quasars never been effectively used as standard candles? Can you tell us about the scientific adventure of COBE? How does the extraction of the Cosmic Microwave Background anisotropy depend on the subtraction of the various astrophysical foregrounds? These, among many others, are the astrophysical, philosophical and sociological questions surrounding modern cosmology and the scientific community that Mauro D'Onofrio and Carlo Burigana pose t...

    Ziółkowska, Justyna

    2009-11-01

    In this article I apply the concept of positioning to the analysis of 15 initial psychiatric interviews. I argue that through their questions the psychiatrists-in-training impose positions requiring the patients to gaze at themselves and their actual problems from particular perspectives. I point to three such positions: (a) the position of the observing assessor, from which it is expected that the patients will make a detached assessment of themselves or their problems, (b) the position of the informing witness, which requires the patients only to verify the information about themselves, and (c) the marginal one, the position of the experiencing narrator, from which talk about experiences and problems is expected. I explore the roots and consequences of the positions, with particular attention toward objectivization of the patients' experiences in the dominant witness and assessor positions. I conclude with a discussion about the medical model in psychiatry.

  20. Questioning Stakeholder Legitimacy: A Philanthropic Accountability Model.

    2017-01-01

    Philanthropic organizations contribute to important work that solves complex problems to strengthen communities. Many of these organizations are moving toward engaging in public policy work, in addition to funding programs. This paper raises questions of legitimacy for foundations, as well as issues of transparency and accountability in a pluralistic democracy. Measures of civic health also inform how philanthropic organizations can be accountable to stakeholders. We propose a holistic model for philanthropic accountability that combines elements of transparency and performance accountability, as well as practices associated with the American pluralistic model for democratic accountability. We argue that philanthropic institutions should seek stakeholder and public input when shaping any public policy agenda. This paper suggests a new paradigm, called philanthropic accountability that can be used for legitimacy and democratic governance of private foundations engaged in policy work. The Philanthropic Accountability Model can be empirically tested and used as a governance tool.

    2012-09-01

    The clinic is a loaded space for LGBTQI persons. Historically a site of pathology and culturally a site of stigma, the contemporary clinic for queer patient populations and their loved ones is an ethically fraught space. This paper, which introduces the featured articles of this special issue of the Journal of Bioethical Inquiry on "Bioethics, Sexuality, and Gender Identity," begins by offering an analysis of scrutiny itself. How do we scrutinize? When is it apt for us to scrutinize? And what are the benefits and perils of clinical and bioethical scrutiny? Bearing in mind these questions, the second half of this paper introduces the feature articles in this special issue in response to such forms of scrutiny. How, why, when, and in what ways to sensitively scrutinize LGBTQI persons in the clinic are the aims of this piece.

    2015-01-01

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

    Using a question and answer format we describe important aspects of using genomic technologies in cancer research. The main challenges are not managing the mass of data, but rather the design, analysis and accurate reporting of studies that result in increased biological knowledge and medical utility. Many analysis issues address the use of expression microarrays but are also applicable to other whole genome assays. Microarray based clinical investigations have generated both unrealistic hyperbole and excessive skepticism. Genomic technologies are tremendously powerful and will play instrumental roles in elucidating the mechanisms of oncogenesis and in devlopingan era of predictive medicine in which treatments are tailored to individual tumors. Achieving these goals involves challenges in re-thinking many paradigms for the conduct of basic and clinical cancer research and for the organization of interdisciplinary collaboration.

    2009-03-01

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

    2010-08-01

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

    2018-04-01

    Introduction Unintended pregnancy has been a concerning public health problem for decades. As we begin to understand the complexities of pregnancy intention and how women experience these pregnancies, reproductive life planning offers a paradigm shift. Methods Reproductive life planning is a patient-centered approach that places a patient's reproductive preferences-whether concrete or ambivalent-at the forefront of her clinical care. Results This process grants women and men the opportunity to consider how reproduction fits within the context of their broader lives. Within a clinical encounter, reproductive life planning allows counseling and care to be tailored to patient preferences. Discussion Although there is great potential for positive public health impacts in unintended pregnancy, contraceptive use and improved preconception health, the true benefit lies within reinforcing reproductive empowerment. Despite recommendations for universal adoption, many questions remain regarding implementation, equity and outcomes.

    2015-01-01

    CERN will be changing mobile telephone operators on 24 June. As the community prepares for the summer switchover, everyone has questions. What brought on the change? Why are we losing our old phone numbers? What kind of improvements will we see? "Just as with every contract at CERN, we issue calls for tenders every few years to ensure we are still receiving the best possible service," explains Tony Cass, from the Communication Systems group within the IT department. "As we came to the end of our contract with Sunrise, we put out a call for tenders, which was won by Swisscom. Not only is their pricing more competitive, they will also be providing better service conditions." The scope of these new service conditions is multifaceted: there will be improvements to the redundancy and reliability of the network as well as modern 4G network coverage in the LHC tunnel. "People will also see their mobile phone bills decrease," says Tony. "This will esp...

  9. Global bioevents and the question of periodicity

    Science.gov (United States)

    Sepkoski, J. John

    The hypothesis of periodicity in extinction is an empirical claim that extinction events, while variable in magnitude, are regular in timing and therefore are serially dependent upon some single, ultimate cause with clocklike behavior. This hypothesis is controversal, in part because of questions regarding the identity and timing of certain extinction events and because of speculations concerning possible catastrophic extraterrestrial forcing mechanisms. New data on extinctions of marine animal genera are presented that display a high degree of periodicity in the Mesozoic and Cenozoic as well as a suggestion of nonstationary periodicity in the late Paleozoic. However, no periodicity is evident among the as yet poorly documented extinction events of the early and middle Paleozoic.

    Full Text Available In the eighties, the question of the moral legitimacy of enhancement related to therapy emerged. In order to approach the issue at the present, the author gives the concept: Bodily Intervention Practices (BIP, characterised by five parameters: M or the material involved in the transformation, TC or the available technoscience, A or the current conceptions regarding the natural and the artificial, N or the concept of human nature culturally shared and E or the ethical evaluations appealed to justify the transformation. The ontological level is indicated as necessary in order to understand the present debate the existing differences in moral criteria. The concept of human nature as a normative reference is in crisis and its absence leaves a vacuum which makes the need for deliberation with the aim of reaching common normative criteria urgent.

    In the United States, the pioneer in nuclear power generation, the economic aspect of nuclear power is now questioned. Its economy in Japan is supported by the entirely monopolistic nature of the power generating firms. The economy of the nuclear power generation in Japan is first examined in its original cost. It is then analyzed in legislative economics. In the conventional arguments, the authorities in favor of nuclear power stick to its practical safety, acknowledging its potential danger, while the people against it adheres to its danger. Thus both arguments go in parallel, never converging. It is attempted to elucidate through the atomic energy damage compensation system, on the boundary between legislation and economy, to whom nuclear power generation is safe, and to whom it is dangerous.

    Ale, Ben J.M.

    2005-01-01

    Public authorities started to be really involved in risk management of hazardous materials some 30 years ago. Recent developments have led to fresh attention for this matter and many further developments are underway. The history of risk management and safety regulation is one of strongly variable interest, forgotten lessons and rude awakenings. The impetus exerted by accidents is short lived. Safety cases become documents to satisfy regulation rather than instruments to reduce risk. Deregulation, privatisation, and outsourcing pose new challenges to safety and risk management. Some of the unfortunate side effects have already become apparent. This invariably leads to the next disaster, which will have a striking resemblance to the previous one when abstracted from the immediate technological context. Lessons can be learned if we really want. The question remains: 'Do we?'

  13. Autoantibodies in systemic sclerosis: Unanswered questions

    Directory of Open Access Journals (Sweden)

    CRISTIANE eKAYSER

    2015-04-01

    Full Text Available Systemic sclerosis (SSc is an autoimmune disease characterized by vascular abnormalities, and cutaneous and visceral fibrosis. Serum autoantibodies directed to multiple intracellular antigens are present in more than 95% of patients and are considered a hallmark of SSc. They are helpful biomarkers for the early diagnosis of SSc and are associated with distinctive clinical manifestations. With the advent of more sensitive, multiplexed immunoassays, new and old questions about the relevance of autoantibodies in SSc are emerging. In this review we discuss the clinical relevance of autoantibodies in SSc emphasizing the more recently published data. Moreover, we will summarize recent advances regarding the stability of SSc autoantibodies over the course of disease, whether they are mutually exclusive and their potential roles in the disease pathogenesis.

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

  15. Immigration and Competitiveness – Some Methodological Questions

    Tünde Patay

    2017-12-01

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

    2010-10-01

    Survey research is a unique methodology that can provide insight into individuals' perspectives and experiences and can be collected on a large population-based sample. Specifically, in plastic surgery, survey research can provide patients and providers with accurate and reproducible information to assist with medical decision-making. When using survey methods in research, researchers should develop a conceptual model that explains the relationships of the independent and dependent variables. The items of the survey are of primary importance. Collected data are only useful if they accurately measure the concepts of interest. In addition, administration of the survey must follow basic principles to ensure an adequate response rate and representation of the intended target sample. In this article, the authors review some general concepts important for successful survey research and discuss the many advantages this methodology has for obtaining limitless amounts of valuable information.

    2011-06-01

    Relatives often lack important information about intensive care unit patients. High-quality information is crucial to help relatives overcome the often considerable situational stress and to acquire the ability to participate in the decision-making process, most notably regarding the appropriate level of care. We aimed to develop a list of questions important for relatives of patients in the intensive care unit. This was a multicenter study. Questions asked by relatives of intensive care unit patients were collected from five different sources (literature, panel of 28 intensive care unit nurses and physicians, 1-wk survey of nurses and 1-wk survey of physicians in 14 intensive care units, and in-depth interviews with 14 families). After a qualitative analysis (framework approach and thematic analysis), questions were rated by 22 relatives and 14 intensive care unit physicians, and the ratings were analyzed using principal component analysis and hierarchical clustering. The five sources produced 2,135 questions. Removal of duplicates and redundancies left 443 questions, which were distributed among nine predefined domains using a framework approach ("diagnosis," "treatment," "prognosis," "comfort," "interaction," "communication," "family," "end of life," and "postintensive care unit management"). Thematic analysis in each domain led to the identification of 46 themes, which were reworded as 46 different questions. Ratings by relatives and physicians showed that 21 of these questions were particularly important for relatives of intensive care unit patients. This study increases knowledge about the informational needs of relatives of intensive care unit patients. This list of questions may prove valuable for both relatives and intensive care unit physicians as a tool for improving communication in the intensive care unit.

  1. 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.

    A survey supported by SEMATECH and administered by David Powell Consulting was sent to semiconductor industry leaders to gather information about the mask industry as an objective assessment of its overall condition. The survey was designed with the input of semiconductor company mask technologists and merchant mask suppliers. 2012 marks the 11th consecutive year for the mask industry survey. This year's survey and reporting structure are similar to those of the previous years with minor modifications based on feedback from past years and the need to collect additional data on key topics. Categories include general mask information, mask processing, data and write time, yield and yield loss, delivery times, and maintenance and returns. Within each category are multiple questions that result in a detailed profile of both the business and technical status of the mask industry. Results, initial observations, and key comparisons between the 2011 and 2012 survey responses are shown here, including multiple indications of a shift towards the manufacturing of higher end photomasks.

    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.

    A critical question regarding volcano-pluton links is whether plutons are samples of magma that passed through on its way to eruption, or residues left behind after volcanic rocks were extracted. A persistent theme of recent work on granites sensu lato is that many are sedimentary accumulations of crystals that lost significant volumes of magmatic liquid. This view is based on observations of structures that clearly seem to reflect deposition on a magma chamber floor (e.g., flows of chilled mafic magma into silicic magma) and on the inference that many other structures, such as modal layering, truncated layering, and crystal accumulations, reflect crystal sedimentation on such chamber floors. There are significant physical and geochemical reasons to question this view, based on observations in the Sierra Nevada of California and similar results from other batholiths. First, few granites show the enrichments in Ba, Sr, and relative Eu that feldspar accumulation should produce. Second, sedimentary features such as graded bedding and cross-bedding form in highly turbulent flows, but turbulence is unachievable in viscous silicic liquids, where velocities on the order of 104 m/s would be required to induce turbulence in a liquid with η=104 Pa s. Third, tabular modally layered domains commonly cut surrounding modal layering on both sides, and orientations of modal layering and of the troughs of "ladder dikes" commonly scatter widely within hectare-sized areas; it is difficult to reconcile these features with gravity-driven settling. Fourth, accumulations of K-feldspar megacrysts are typically inferred to be depositional, but this is precluded by crystallization of most K- feldspar after rheologic lock-up occurs. Finally, accumulations of K-feldspar and hornblende are typically packed too tightly to be depositional. With analogy to layered mafic intrusions, many features attributed to crystal sedimentation in granites may be better explained by crystal aging and other in

    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.

    markdownabstractMarketing experts commonly refer to ads as either “emotional” or “rational” in their appeal to consumers. This dichotomy of “thinking versus feeling” is most evident when it comes to discussions around what makes an ad effective. Some studies suggest that an ad that pulls on the heart strings will pack the most punch; others suggest a blend of logic and emotion. However, new research reveals which areas of the brain are stimulated by different ad appeals – and the brain activi...

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

  12. Cancer and beyond: the question of survivorship.

    1997-11-01

    Today, more people are surviving cancer as a result of improved treatment and early diagnosis. In Australia, the 5-year survival rate for persons diagnosed with cancer is now approaching 50%. Although there is a growing population of cancer survivors, little is known about what surviving entails. Traditionally, a survivor has been defined as one who has been disease-free for more than 5 years. However, this definition does not take into account the experience nor the process of survival and the aim of this article is to document the process of surviving cancer as reflected in the experiences of cancer survivors. Using a method of hermeneutic phenomenology (as described by van Manen), the study draws on the stories of six women, who by their definition, are surviving cancer. A discussion of themes has been structured according to the everyday experiences of living in a body and living in time. The women describe a survival process that includes: 'feeling whole again'; 'the body as the house of suspicion'; 'the future in question'; 'changes in time'; 'lucky to be alive'; and 'sharing the journey'.

  13. Discovery Mondays - Mass: a question of weight?

    CERN Multimedia

    2006-01-01

    Mass and weight: two rather commonplace phenomena on the surface of it, but would you be able to explain the difference between them? And do you know how gravity works? If you let go of a paperclip and an apple at the same time, which of the two will hit the floor first? At the next Discovery Monday scientists will introduce you to these concepts that are often rather difficult to get to grips with. Find out what kind of particles are thought to be responsible for mass and gravity. Get to know the graviton, a particle that has yet to be observed, has no mass or charge but is thought to be a messenger particle for gravity. You will also encounter the famous Higgs boson, which scientists believe could elucidate the mystery of mass and hope to discover with the LHC. An evening for tackling some very weighty questions... The event will be conducted in French. Join us at Microcosm (Reception, Building 33, Meyrin site), on Monday 6 March from 7.30 p.m. to 9.00 p.m. Entrance Free http://www.cern.ch/LundisDeco...

    Full Text Available We briefly review the properties of radially growing interfaces and their connection to biological growth. We focus on simplified models which result from the abstraction of only considering domain growth and not the interface curvature. Linear equations can be exactly solved and the phenomenology of growth can be inferred from the explicit solutions. Nonlinear equations pose interesting open questions that are summarized herein.

    En este trabajo revisamos brevemente las propiedades de las superficies que crecen de forma radial y su conexión con el crecimiento biológico. Nos vamos a concentrar en modelos simplificados que resultan de la abstracción de sólo considerar el crecimiento del dominio y no la curvatura de la interfaz. Las ecuaciones lineales se pueden resolver exactamente y la fenomenología del crecimiento puede ser inferida de las soluciones explítas. Las ecuaciones no lineales dan lugar a interesantes problemas abiertos que vamos a resumir aquí.

    Glutamate receptors of the N-methyl-D-aspartate (NMDA) type are involved in many cognitive processes, including behavior, learning and synaptic plasticity. For a long time NMDA receptors were thought to be the privileged domain of neurons; however, discoveries of the last 25 years have demonstrated their active role in glial cells as well. Despite the large number of studies in the field, there are many unresolved questions connected with NMDA receptors in glia that are still a matter of debate. The main objective of this review is to shed light on these controversies by summarizing results from all relevant works concerning astrocytes, oligodendrocytes and polydendrocytes (also known as NG2 glial cells) in experimental animals, further extended by studies performed on human glia. The results are divided according to the study approach to enable a better comparison of how findings obtained at the mRNA level correspond with protein expression or functionality. Furthermore, special attention is focused on the NMDA receptor subunits present in the particular glial cell types, which give them special characteristics different from those of neurons - for example, the absence of Mg(2+) block and decreased Ca(2+) permeability. Since glial cells are implicated in important physiological and pathophysiological roles in the central nervous system (CNS), the last part of this review provides an overview of glial NMDA receptors with respect to ischemic brain injury.

  16. Cyber security: a question of method

    International Nuclear Information System (INIS)

    Cappelle, A.

    2016-01-01

    Industrial devices are more and more connected which has generated numerous weaknesses and flaws in networks. Most attacks concern basic things. The French law about military programming defines vital infrastructures whose operators must comply with a minimal cyber security standard. These vital infrastructures include water treatment plants, nuclear power plants or hospitals. In last december the black-ware BlackEnergy enabled hackers to access the management systems of several power plants in Ukraine causing a huge power outage. Technical solutions exist but solving this issue is above all a question of method: you must study your network, identifying the fluxes of information and then to set adequate solutions at the right places. By positioning components able to analyse fluxes you can detect abnormal fluxes and bar the access. The right settings of software like firewalls are an important thing to get a high standard of security. For external communication efficient encoding solutions exist that ensure a high level of secrecy and can identify the contact person. (A.C.)

  17. 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.

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

    2014-12-01

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