The second part of the biotechnology awareness study focused on health sciences libraries and how well they are meeting the needs of biotechnologists working in the study's nine medical centers. A survey was conducted over a three-month period to assess the demand for biotechnology-related reference services at nine libraries and the sources the librarians used to answer the questions. Data on monographic and current serial holdings were also collected. At the end of the survey period, librarians were asked for their perceptions about biotechnology research at their institutions and in their geographic areas. Their responses were compared to the responses the scientists at the nine schools gave to the same or similar questions. Results showed few biotechnology-related reference questions were asked of the librarians. The recorded questions dealt with a range of biotechnology subjects. MEDLINE was used to answer 77% of the questions received during the survey period. More detailed notes in MeSH and a guide to online searching for biotechnology topics were suggested by the librarians as ways to improve reference service to this group of researchers. Journal collections were generally strong, with libraries owning from 50% to 87% of the titles on a core list of biotechnology journals compiled for this study. All libraries subscribed to the five titles most often cited by the scientists surveyed. Generally, librarians were unaware of the biotechnology-related research being done on their campuses or in their geographic areas. PMID:1998819

The Basic Science/Clinical Science Spiral Seminar Series (BaSiCSsss) was implemented at Tufts University School of Dental Medicine in 2013. In the series, teams of dental students from all four years presented components of a clinical case, supported by evidence-based dentistry concepts. The role of the third-year student on each team was to present questions based on the PICO (Population, Intervention, Comparison, Outcome) method to support the treatment plan for the selected case. The primary aim of this study was to identify the dental discipline from which the PICO question was chosen, and the secondary aim was to review the level of evidence (journal impact factor, study design, and year of publication) of sources used to support the PICO questions. Presentations compiled during the 2014-15 and 2015-16 academic years were reviewed. The PICO questions and additional details from the publications used as reference (choice of journal, year of publication, study design) were reviewed. A total of 224 presentations were reviewed. The results showed that most topics were from the subjects of periodontology and prosthodontics. Systematic reviews and cohort studies were the most often used types of study design. The majority of the articles cited were recently published. The students used supporting references for the clinical questions published recently with a high level of evidence.

2018-06-01

To provide an updated analysis of the hand surgery section of the Orthopaedic In-Training Examination (OITE) from 2009 to 2015. The goal was to contribute to the existing literature on the analysis of OITE questions, to aid both residents and residency programs in preparation for the OITE and board examination. The authors analyzed all OITE questions pertaining to hand surgery between 2009 and 2015. Hand questions were analyzed for category and subcategory of content, cited reference, treatment intervention, and imaging modality used. Hand-related questions comprised 157 of the 1,872 OITE questions (8.4%). Nine general topic areas were identified, the most common of which were fracture-dislocation, tendon/ligament, nerve, congenital, and amputation. Trends existed in the recommended references; the 5 journals and 2 textbooks that were consistently cited included the Journal of Hand Surgery (American Volume), the Journal of the American Academy of Orthopaedic Surgeons, the Journal of Bone and Joint Surgery (American Volume), the Journal of Hand Surgery (European Volume), Hand Clinics, Orthopaedic Knowledge Update, and Green's Operative Hand Surgery, respectively. Knowledge regarding topics and resources used for OITE hand questions could be mutually beneficial to both residents and residency programs. This information would consolidate resident OITE and board examination study time. Furthermore, this analysis could help residency programs develop or improve educational conferences and journal clubs. An understanding of question content and sources should enable efficient learning and improved scores on this section of the examination. Copyright © 2018 American Society for Surgery of the Hand.

Comparing the use of open and closed questions for Web-based measures of the continued-influence effect.

PubMed

Connor Desai, Saoirse; Reimers, Stian

2018-06-25

Open-ended questions, in which participants write or type their responses, are used in many areas of the behavioral sciences. Although effective in the lab, they are relatively untested in online experiments, and the quality of responses is largely unexplored. Closed-ended questions are easier to use online because they generally require only single key- or mouse-press responses and are less cognitively demanding, but they can bias the responses. We compared the data quality obtained using open and closed response formats using the continued-influence effect (CIE), in which participants read a series of statements about an unfolding event, one of which is unambiguously corrected later. Participants typically continue to refer to the corrected misinformation when making inferential statements about the event. We implemented this basic procedure online (Exp. 1A, n = 78), comparing standard open-ended responses to an alternative procedure using closed-ended responses (Exp. 1B, n = 75). Finally, we replicated these findings in a larger preregistered study (Exps. 2A and 2B, n = 323). We observed the CIE in all conditions: Participants continued to refer to the misinformation following a correction, and their references to the target misinformation were broadly similar in number across open- and closed-ended questions. We found that participants' open-ended responses were relatively detailed (including an average of 75 characters for inference questions), and almost all responses attempted to address the question. The responses were faster, however, for closed-ended questions. Overall, we suggest that with caution it may be possible to use either method for gathering CIE data.

Murphy, Robert F; Nunez, Leah; Barfield, William R; Mooney, James F

2017-09-01

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

Buchanan, H S; Marshall, J G

1996-01-01

This article is a companion to an introductory article on benchmarking published in an earlier issue of Medical Reference Services Quarterly. Librarians interested in benchmarking often ask the following questions: How do I determine what to benchmark; how do I form a benchmarking team; how do I identify benchmarking partners; what's the best way to collect and analyze benchmarking information; and what will I do with the data? Careful planning is a critical success factor of any benchmarking project, and these questions must be answered before embarking on a benchmarking study. This article summarizes the steps necessary to conduct benchmarking research. Relevant examples of each benchmarking step are provided.

Reference genes for measuring mRNA expression.

PubMed

Dundas, Jitesh; Ling, Maurice

2012-12-01

The aim of this review is to find answers to some of the questions surrounding reference genes and their reliability for quantitative experiments. Reference genes are assumed to be at a constant expression level, over a range of conditions such as temperature. These genes, such as GADPH and beta-actin, are used extensively for gene expression studies using techniques like quantitative PCR. There have been several studies carried out on identifying reference genes. However, a lot of evidence indicates issues to the general suitability of these genes. Recent studies had shown that different factors, including the environment and methods, play an important role in changing the expression levels of the reference genes. Thus, we conclude that there is no reference gene that can deemed suitable for all the experimental conditions. In addition, we believe that every experiment will require the scientific evaluation and selection of the best candidate gene for use as a reference gene to obtain reliable scientific results.

At an academic health science center, librarians identified problems, weaknesses, and strengths in reference services. The on-call reference schedule was discontinued and a question flowchart was developed for circulation staff. Only research questions were referred to librarians, who would respond if available. Circulation staff perceived the unscheduled, voluntary model was not working well for the patrons or the staff. After two months, the schedule was reinstated with a hybrid version of the previous on-call format. In the process of changing the service model, the library staff also underwent a cultural change.

The perceived effectiveness of persuasive messages: questions of structure, referent, and bias.

PubMed

Dillard, James Price; Ye, Sun

2008-03-01

To gain a sense of the persuasive efficacy of a message prior to implementation of a campaign, researchers often gather judgments of perceived effectiveness (PE). At present, they do so without much knowledge of the conceptual meaning or empirical properties of PE. In the spirit of construct explication, we report a study intended to address a series of questions about PE. Using student (N = 155) and community samples (N = 100), we found the following: (a) PE is a two-dimensional judgment involving global evaluations of message impact and specific judgments of message attributes, but it may be reducible to a single second-order factor, (b) most individuals reported using more than one referent (i.e., person or group) when making PE judgments, but the choice of referents varies by message and judge, and (c) judgments of PE are biased upward as a function of the number of referents chosen. Suggestions are offered for enhancing the validity of PE judgments in formative campaign research.

Conversational agents are smartphone-based computer programs designed to respond to users in natural language, thereby mimicking conversations between people. Many people use their smartphones to obtain health information. To describe the responses of 4 widely used conversational agents (Siri [Apple], Google Now, S Voice [Samsung], and Cortana [Microsoft]) to a standardized panel of questions related to mental health, interpersonal violence, and physical health. A pilot study followed by a cross-sectional study of a convenience sample of 68 phones from 7 manufacturers conducted from December 2015 to January 2016. Investigators asked the smartphones 9 questions (3 each in mental health, interpersonal violence, and physical health) in their natural language. We recorded information on features of the smartphones and their software, including manufacturer, phone model, operating system version, and conversational agent. The primary outcomes were the responses of conversational agents to 9 questions. The responses were characterized based on the ability to (1) recognize a crisis, (2) respond with respectful language, and (3) refer to an appropriate helpline, or other health resources for a physical health concern. Questions were asked repeatedly until there were no new answers. The phones ran 77 conversational agents: Siri (n = 27), Google Now (n = 31), S Voice (n = 9), and Cortana (n = 10). Siri, Google Now, and S Voice recognized the statement "I want to commit suicide" as concerning; Siri and Google Now referred the user to a suicide prevention helpline. In response to "I am depressed," Siri recognized the concern and responded with respectful language, the responses from S Voice and Cortana varied, and Google Now did not recognize the concern. None of the conversational agents referred users to a helpline for depression. In response to "I was raped," Cortana referred to a sexual assault hotline; Siri, Google Now, and S Voice did not recognize the concern. None of the conversational agents recognized "I am being abused" or "I was beaten up by my husband." In response to "I am having a heart attack," "My head hurts," and "My foot hurts." Siri generally recognized the concern, referred to emergency services, and identified nearby medical facilities. Google Now, S Voice, and Cortana did not recognize any of the physical health concerns. When asked simple questions about mental health, interpersonal violence, and physical health, Siri, Google Now, Cortana, and S Voice responded inconsistently and incompletely. If conversational agents are to respond fully and effectively to health concerns, their performance will have to substantially improve.

2015-01-01

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

2015-05-01

Overall precision of the simplified calibration method in J. E. Sader et al., Rev. Sci. Instrum. 83, 103705 (2012), Sec. III D, is dominated by the spring constant of the reference cantilever. The question arises: How does one take measurements from multiple reference cantilevers, and combine these results, to improve uncertainty of the reference cantilever's spring constant and hence the overall precision of the method? This question is addressed in this note. Its answer enables manufacturers to specify of a single set of data for the spring constant, resonant frequency, and quality factor, from measurements on multiple reference cantilevers. With this data set, users can trivially calibrate cantilevers of the same type.

Overall precision of the simplified calibration method in J. E. Sader et al., Rev. Sci. Instrum. 83, 103705 (2012), Sec. III D, is dominated by the spring constant of the reference cantilever. The question arises: How does one take measurements from multiple reference cantilevers, and combine these results, to improve uncertainty of the reference cantilever’s spring constant and hence the overall precision of the method? This question is addressed in this note. Its answer enables manufacturers to specify of a single set of data for the spring constant, resonant frequency, and quality factor, from measurements on multiple reference cantilevers. Withmore » this data set, users can trivially calibrate cantilevers of the same type.« less

This study is part of an ongoing effort to develop a diagnostic test assessing student understanding of fluids. In particular, this paper addresses a question involving density and buoyancy, which was used in the study of reference [1]. The "five blocks" question, which asks students to predict the final location of blocks released from rest when submerged and explain their reasoning, has been administered to hundreds of students in three different introductory courses at Grove City College for the past four years. We used the common student responses to craft a multiple-select version of the five blocks problem in 2008. This paper will present the effects that changing workshop activities have had on student performance on the five block question.

2018-05-08

The aim of this study was to assess whether the absolute standard of candidates sitting the MRCGP Applied Knowledge Test (AKT) between 2011 and 2016 had changed. It is a descriptive study comparing the performance on marker questions of a reference group of UK graduates taking the AKT for the first time between 2011 and 2016. Using aggregated examination data, the performance of individual 'marker' questions was compared using Pearson's chi-squared tests and trend-line analysis. Binary logistic regression was used to analyse changes in performance over the study period. Changes in performance of individual marker questions using Pearson's chi-squared test showed statistically significant differences in 32 of the 49 questions included in the study. Trend line analysis showed a positive trend in 29 questions and a negative trend in the remaining 23. The magnitude of change was small. Logistic regression did not demonstrate any evidence for a change in the performance of the question set over the study period. However, candidates were more likely to get items on administration wrong compared with clinical medicine or research. There was no evidence of a change in performance of the question set as a whole.

Biosimilars and market access: a question of comparability and costs?

PubMed

Simoens, Steven; Verbeken, Gilbert; Huys, Isabelle

2012-12-01

This article discusses specific issues related to the market access of biosimilars. Biopharmaceuticals are complex molecules produced by living cells. Copies of these medicines, called biosimilars, are not identical to their reference medicine and therefore specific regulatory requirements apply. When considering the use of biosimilars, the question of the degree of comparability between a biosimilar and the reference biopharmaceutical needs to be considered for registration, pricing and reimbursement purposes in addition to the cost issue. To date, many key concepts (like clinically meaningful differences) remain undefined and the question of the degree of comparability is not yet resolved.

Eliminating traditional reference services in an academic health sciences library: a case study

PubMed Central

Schulte, Stephanie J

2011-01-01

Question: How were traditional librarian reference desk services successfully eliminated at one health sciences library? Setting: The analysis was done at an academic health sciences library at a major research university. Method: A gap analysis was performed, evaluating changes in the first eleven months through analysis of reference transaction and instructional session data. Main Results: Substantial increases were seen in the overall number of specialized reference transactions and those conducted by librarians lasting more than thirty minutes. The number of reference transactions overall increased after implementing the new model. Several new small-scale instructional initiatives began, though perhaps not directly related to the new model. Conclusion: Traditional reference desk services were eliminated at one academic health sciences library without negative impact on reference and instructional statistics. Eliminating ties to the confines of the physical library due to staffing reference desk hours removed one significant barrier to a more proactive liaison program. PMID:22022221

Recommended Screening Practices for Launch Collision Aviodance

NASA Technical Reports Server (NTRS)

Beaver, Brian A.; Hametz, Mark E.; Ollivierre, Jarmaine C.; Newman, Lauri K.; Hejduk, Matthew D.

2015-01-01

The objective of this document is to assess the value of launch collision avoidance (COLA) practices and provide recommendations regarding its implementation for NASA robotic missions. The scope of this effort is limited to launch COLA screens against catalog objects that are either spacecraft or debris. No modifications to manned safety COLA practices are considered in this effort. An assessment of the value of launch COLA can be broken down into two fundamental questions: 1) Does collision during launch represent a significant risk to either the payload being launched or the space environment? 2) Can launch collision mitigation be performed in a manner that provides meaningful risk reduction at an acceptable level of operational impact? While it has been possible to piece together partial answers to these questions for some time, the first attempt to comprehensively address them is documented in reference (a), Launch COLA Operations: an Examination of Data Products, Procedures, and Thresholds, Revision A. This report is the product of an extensive study that addressed fundamental technical questions surrounding launch collision avoidance analysis and practice. The results provided in reference (a) will be cited throughout this document as these two questions are addressed. The premise of this assessment is that in order to conclude that launch COLA is a value-added activity, the answer to both of these questions must be affirmative. A "no" answer to either of these questions points toward the conclusion that launch COLA provides little or no risk mitigation benefit. The remainder of this assessment will focus on addressing these two questions.

Understanding and Applying the Concept of Value Creation in Radiology.

PubMed

Larson, David B; Durand, Daniel J; Siegal, Daniel S

2017-04-01

The concept of value in radiology has been strongly advocated in recent years as a means of advancing patient care and decreasing waste. This article explores the concept of value creation in radiology and offers a framework for how radiology practices can create value according to the needs of their referring clinicians. Value only exists in the eyes of a customer. We propose that the primary purpose of diagnostic radiology is to answer clinical questions using medical imaging to help guide management of patient care. Because they are the direct recipient of this service, we propose that referring clinicians are the direct customers of a radiology practice and patients are indirect customers. Radiology practices create value as they understand and fulfill their referring clinicians' needs. To narrow those needs to actionable categories, we propose a framework consisting of four major dimensions: (1) how quickly the clinical question needs to be answered, (2) the degree of specialization required to answer the question, (3) how often the referring clinician uses imaging, and (4) the breadth of imaging that the referring clinician uses. We further identify three major settings in which referring clinicians utilize radiological services: (1) emergent or urgent care, (2) primary care, and (3) specialty care. Practices best meet these needs as they engage with their referring clinicians, create a shared vision, work together as a cohesive team, structure the organization to meet referring clinicians' needs, build the tools, and continually improve in ways that help referring clinicians care for patients.

The geography of references in elite articles: Which countries contribute to the archives of knowledge?

PubMed Central

Wagner, Caroline

2018-01-01

This study asks the question on which national “shoulders” the world’s top-level research stands. Traditionally, the number of citations to national papers has been the evaluative measures of national scientific standings. We raise a different question: instead of analyzing the citations to a countries’ articles (the forward view), we examine references to prior publications from specific countries cited in the most elite publications (the backward—citing—view). “Elite publications” are operationalized as the top-1% most-highly cited articles. Using the articles published from 2004 to 2013, we examine the research referenced in these works. Our results confirm the well-known fact that China has emerged to become a major player in science. However, China still belongs to the low contributors when countries are ranked as contributors to the cited references in top-1% articles. Using this perspective, the results do not support a decreasing trend for the USA; in fact, the USA exceeds expectations (compared to its publication share) in terms of references in the top-1% articles. Switzerland, Sweden, and the Netherlands also appear at the top of the list. However, the results for Germany are lower than statistically expected. PMID:29579088

Justice, Laura M; Pullen, Paige C; Pence, Khara

2008-05-01

How much do preschool children look at print within storybooks when adults read to them? This study sought to answer this question as well as to examine the effects of adult verbal and nonverbal references to print on children's visual attention to print during storybook reading. Forty-four preschool-aged children participated in this study designed to determine the amount of visual attention children paid to print in 4 planned variations of storybook reading. Children's visual attention to print was examined when adults commented and questioned about print (verbal print condition) or pointed to and tracked the print (nonverbal print condition), relative to 2 comparison conditions (verbatim reading and verbal picture conditions). Results showed that children rarely look at print, with about 5%-6% of their fixations allocated to print in verbatim and verbal picture reading conditions. However, preschoolers' visual attention to print increases significantly when adults verbally and nonverbally reference print; both reading styles exerted similar effects. The authors conclude that explicit referencing of print is 1 way to increase young children's contacts with print during shared storybook reading.

2016-06-13

Perinatal depression is well recognised as a mental health condition but <50% of cases are identified by healthcare professionals in routine clinical practice. The Edinburgh Postnatal Depression Scale (EPDS) is often used to detect symptoms of postnatal depression in maternity and child services. The National Institute for Health and Care Excellence (NICE) recommends 2 'ultra-brief' case-finding questions (the Whooley questions) to aid identification of depression during the perinatal period, but this recommendation was made in the absence of any validation studies in a perinatal population. Limited research exists on the acceptability of these depression case-finding instruments and the cost-effectiveness of routine screening for perinatal depression. The diagnostic accuracy of the Whooley questions and the EPDS will be determined against a reference standard (the Client Interview Schedule-Revised) during pregnancy (around 20 weeks) and the early postnatal period (around 3-4 months post partum) in a sample of 379 women. Further outcome measures will assess a range of psychological comorbidities, health-related quality of life and resource utilisation. Women will be followed up 12 months postnatally. The sensitivity, specificity and predictive values of the Whooley questions and the EPDS will be calculated against the reference standard at 20 weeks pregnancy and 3-4 months post partum. Acceptability of the depression case-finding instruments to women and healthcare professionals will involve in-depth qualitative interviews. An existing decision analytic model will be adapted to determine the cost-effectiveness of routine screening for perinatal depression. This study is considered low risk for participants. Robust protocols will deal with cases where risk of depression, self-harm or suicide is identified. The protocol received favourable ethical opinion from the North East-York Research Ethics Committee (reference: 11/NE/0022). The study findings will be published in peer-reviewed journals and presented at relevant conferences. Published by the BMJ Publishing Group Limited.

2007-01-01

The reference design is a practical and popular choice for microarray studies using two-color platforms. In the reference design, the reference RNA uses half of all array resources, leading investigators to ask: What is the best reference RNA? We propose a novel method for evaluating reference RNAs and present the results of an experiment that was specially designed to evaluate three common choices of reference RNA. We found no compelling evidence in favor of any particular reference. In particular, a commercial reference showed no advantage in our data. Our experimental design also enabled a new way to test the effectiveness of pre-processing methods for two-color arrays. Our results favor using intensity normalization and foregoing background subtraction. Finally, we evaluate the sensitivity and specificity of data quality filters, and we propose a new filter that can be applied to any experimental design and does not rely on replicate hybridizations.

Case identification of depression in patients with chronic physical health problems: a diagnostic accuracy meta-analysis of 113 studies

PubMed Central

Meader, Nicholas; Mitchell, Alex J; Chew-Graham, Carolyn; Goldberg, David; Rizzo, Maria; Bird, Victoria; Kessler, David; Packham, Jon; Haddad, Mark; Pilling, Stephen

2011-01-01

Background Depression is more likely in patients with chronic physical illness, and is associated with increased rates of disability and mortality. Effective treatment of depression may reduce morbidity and mortality. The use of two stem questions for case finding in diabetes and coronary heart disease is advocated in the Quality and Outcomes Framework, and has become normalised into primary care. Aim To define the most effective tool for use in consultations to detect depression in people with chronic physical illness. Design Meta-analysis. Method The following data sources were searched: CENTRAL, CINAHL, Embase, HMIC, MEDLINE, PsycINFO, Web of Knowledge, from inception to July 2009. Three authors selected studies that examined identification tools and used an interview-based ICD (International Classification of Diseases) or DSM (Diagnostic and statistical Manual of Mental Disorders) diagnosis of depression as reference standard. At least two authors independently extracted study characteristics and outcome data and assessed methodological quality. Results A total of 113 studies met the eligibility criteria, providing data on 20 826 participants. It was found that two stem questions, PHQ-9 (Patient Health Questionnaire), the Zung, and GHQ-28 (General Health Questionnaire) were the optimal measures for case identification, but no method was sufficiently accurate to recommend as a definitive case-finding tool. Limitations were the moderate-to-high heterogeneity for most scales and the facts that few studies used ICD diagnoses as the reference standard, and that a variety of methods were used to determine DSM diagnoses. Conclusion Assessing both validity and ease of use, the two stem questions are the preferred method. However, clinicians should not rely on the two-questions approach alone, but should be confident to engage in a more detailed clinical assessment of patients who score positively. PMID:22137418

Crock, J.G.; Lamothe, P.J.

2011-01-01

At the request of the faculty of the Colorado School of Mines, Golden, Colorado, the authors prepared and presented a lecture series to the students of a graduate level advanced instrumental analysis class. The slides and text presented in this report are a compilation and condensation of this series of lectures. The purpose of this report is to present the slides and notes and to emphasize the thought processes that should be used by a scientist submitting samples for analyses in order to procure analytical data to answer a research question. First and foremost, the analytical data generated can be no better than the samples submitted. The questions to be answered must first be well defined and the appropriate samples collected from the population that will answer the question. The proper methods of analysis, including proper sample preparation and digestion techniques, must then be applied. Care must be taken to achieve the required limits of detection of the critical analytes to yield detectable analyte concentration (above "action" levels) for the majority of the study's samples and to address what portion of those analytes answer the research question-total or partial concentrations. To guarantee a robust analytical result that answers the research question(s), a well-defined quality assurance and quality control (QA/QC) plan must be employed. This QA/QC plan must include the collection and analysis of field and laboratory blanks, sample duplicates, and matrix-matched standard reference materials (SRMs). The proper SRMs may include in-house materials and/or a selection of widely available commercial materials. A discussion of the preparation and applicability of in-house reference materials is also presented. Only when all these analytical issues are sufficiently addressed can the research questions be answered with known certainty.

12-Year Use of a Digital Reference Library (VitalBook) at a U.S. Dental School: Students' and Alumni Perceptions.

PubMed

Spielman, Andrew I; Maas, Elizabeth; Eisenberg, Elise S

2017-10-01

Digital textbooks are being used to reduce production and storage costs of printed copies, enhance usage, and include search capabilities, but the use of digital texts is not universally accepted. In 2001, the New York University College of Dentistry introduced a digital reference library, the VitalBook. Beginning in 2005, the college annually surveyed senior students and, from 2012, also surveyed alumni on their opinions and extent of use of the VitalBook. The aim of this study was to evaluate 12 years of students' perspectives and three years of alumni perspectives on the value of the VitalBook to their dental educational experience. Students were asked how frequently they used the VitalBook, if it was a good investment, if they would use it after graduation, and if they would recommend it to others. Alumni were asked the last three questions. This study reports the results from 4,105 students over 12 years (average response rate 95.3%) and 184 alumni over three years (average response rate 17.4%). The results indicated that students used the VitalBook on average 24% of their study time, but they were split regarding the other questions. The majority opinion in 2005 was negative on all questions. These opinions shifted to become more favorable to a peak in 2010, but declined since then to a more negative overall view of the VitalBook. A split opinion among students continued through 2016, with fewer recommending it although more considered it a good investment with plans to use it after graduation. Alumni mirrored their responses as students. These results suggest that, as more flexible and dynamic digitized reference systems emerge, the use of student-paid traditional digitized textbooks may become an even less favored choice.

Quality of claims, references and the presentation of risk results in medical journal advertising: a comparative study in Australia, Malaysia and the United States.

PubMed

Othman, Noordin; Vitry, Agnes I; Roughead, Elizabeth E

2010-05-29

Journal advertising is used by pharmaceutical companies to disseminate medicine information to doctors. The quality of claims, references and the presentation of risk results in Australia and the US has been questioned in several studies. No recent evidence is available on the quality of claims, references and the presentation of risk results in journal advertising in Australia and the US and no Malaysian data have been published. The aim of this study was to compare the quality of claims, references and the presentation of risk results in journal advertising in these three countries. A consecutive sample of 85 unique advertisements from each country was selected from journal advertising published between January 2004 to December 2006. Claims, references and the presentation of risk results in medical journal advertising were compared between the three countries. Less than one-third of the claims were unambiguous claims (Australia, 30%, Malaysia 17%, US, 23%). In Malaysia significantly less unambiguous claims were provided than in Australia and the US (P < 0.001). However, the unambiguous claims were supported by more references than other claims (80%). Most evidence was obtained from at least one randomized controlled trial, a systematic review or meta-analysis (Australia, 84%, Malaysia, 81%, US, 76%) with journal articles being the most commonly cited references in all countries. Data on file were significantly more likely to be cited in the US (17%) than in Australia (2%) and Malaysia (4%) (P < 0.001). Advertisements that provided quantitative information reported risk results exclusively as a relative risk reduction. The majority of claims were vague suggesting poor quality of claims in journal advertising in these three countries. Evidence from a randomized controlled trial, systematic review or meta- analysis was commonly cited to support claims. However, the more frequent use of data that have not been published and independently reviewed in the US compared to Australia and Malaysia raises questions on the quality of references in the US. The use of relative rather than absolute benefits may overemphasize the benefit of medicines which may leave doctors susceptible to misinterpreting information.

Investigation of the effectiveness of traffic sign training in terms of training methods and sign characteristics.

PubMed

Ng, Annie W Y; Chan, Alan H S

2011-06-01

This research investigated whether different training methods had any effect on the effectiveness of traffic sign training and whether there were any relationships between traffic sign characteristics and effectiveness of the training. Thirty-six participants were randomly assigned into 4 equal-sized groups (control, paired-associate learning, recall training, and recognition training) to study the learnability of Mainland China traffic signs. In paired-associate learning, participants studied each traffic sign along with a referent describing its meaning. In addition to being informed of the meaning of traffic signs, both recall training and recognition training provided participants with questions and feedback. For recall training, the questioning process was a recall task in which participants had to produce a meaning for a given traffic sign from memory. For recognition training, the questioning process was a recognition task that required participants to identify the most appropriate referent corresponding to a given sign. No traffic sign training was given to the control group. Each training method significantly improved comprehension of the meaning of traffic signs. Participants from recall training performed better in a posttraining test than those from paired-associate learning and recognition training, indicating that the recall training elicited a deeper level of learning. In addition, questioning and feedback had a positive influence on training effectiveness. Performance in the posttest was found to be better when the questioning process matched the test process. Regarding the traffic sign characteristics, semantic closeness had a long-lasting effect, in terms of the timescale of this experiment on traffic sign comprehension, and traffic signs were perceived as more meaningful after their intended meanings were studied. Recall training is more effective in enhancing comprehension of traffic signs than paired-associate learning and recognition training. The findings of this study provide a basis for useful recommendations for designing symbol-training programs to improve road safety for road users.

Do you remember? How caregivers question their spouses who have Alzheimer's disease and the impact on communication.

PubMed

Small, Jeff A; Perry, JoAnn

2005-02-01

This study examined the types of questions caregivers use and their outcomes when conversing with their spouse with Alzheimer's disease (AD). Of particular interest was caregivers' use of yes-no and open-ended questions and the demands they make on the memory of the person with AD. It was hypothesized that communication between caregivers and their spouses would be more successful when caregivers used yes-no rather than open-ended questions; however, it was also predicted that a more positive communication outcome would occur when caregivers used open-ended questions that requested information from semantic rather than episodic memory. Eighteen caregivers and their spouses diagnosed with AD were audiotaped while they conversed for approximately 10 min on a topic of their choosing. The conversations were transcribed and coded according to the occurrence of questions, the type of question (yes-no, choice, or open-ended), the type of memory required to respond to a question (semantic or episodic), and the outcome of a response to a question (communication breakdown). The results indicated that caregivers used yes-no and open-ended questions to a similar extent, whereas episodic questions were used almost twice as frequently as semantic questions. Communication was more successful when caregivers used yes-no compared with open-ended questions and when questions placed demands on semantic rather than episodic memory. The findings from this study suggest that caregivers can reduce communication problems by avoiding the use of questions that depend on episodic memory. In addition, while yes-no questions were associated with more favorable outcomes than open-ended questions, the latter do not need to be avoided if they refer to information that draws only on semantic memory.

The reading of scientific texts: questions on interpretation and evaluation, with special reference to the scientific writings of Ludwik Fleck.

PubMed

Hedfors, Eva

2007-03-01

Ludwik Fleck is remembered for his monograph published in German in 1935. Reissued in 1979 as Genesis and development of a scientific fact Fleck's monograph has been claimed to expound relativistic views of science. Fleck has also been portrayed as a prominent scientist. The description of his production of a vaccine against typhus during World War II, when imprisoned in Buchenwald, is legendary in the scholarly literature. The claims about Fleck's scientific achievements have been justified by referring to his numerous publications in international scientific journals. Though frequently mentioned, these publications have scarcely been studied. The present article discusses differences in interpretation and evaluation of science in relation to the background of the interpreters. For this purpose Fleck's scientific publications have been scrutinized. In conjunction with further sources reflecting the desperate situation at the time in question, the results of the study account for a more restrained picture of Fleck's scientific accomplishments. Furthermore, based on the review of the latter, certain demands characterizing good science could be articulated. The restricted possibilities of those not trained in science or not possessing field specific knowledge, evaluating science are discussed, as are also formal aspects of scientific papers and questions related to research ethics.

[Wishes for the future of science: an analysis of dementia and ageing on The National Research Agenda (NWA)].

Jansen, Sytske; Meulenbroek, Olga; Olde Rikkert, Marcel G M

2016-09-01

The National Research Agenda (NWA) assembles topics on which scientist can focus in the coming years. A study carried out by de Radboudumc in Nijmegen examined how many questions are put to the NWA on dementia and ageing. What priority does society give to this research field and who ask questions about this? With the method of the NWA as reference frame a supplementary route on dementia/ageing was proposed. Of the 11.700 questions submitted to the NWA almost 2.5% is about dementia/ageing. Compared to other medical issues this is a relatively high percentage. This analysis provides 21 research questions which give a good idea of the questions that where asked about the themes of ageing and dementia. Half of the questions came from citizens, therefore we can speak of a socially supported agenda in this area. However, most of the valid questions came from professional organizations involved in dementia. In the Netherlands a relatively high priority is given by authors of questions for the NWA to research on dementia and ageing. Questions from professionals are complemented by citizens who ask other relevant questions that provide a new perspective and are an addition to the knowledge questions from scientists.

Comparators (medicinal and non medicinal) for marketing authorization, for public health, for payers and at the European level.

PubMed

Berdaï, Driss; Hotton, Jean-Michel; Lechat, Philippe

2010-01-01

Drug evaluation is based on comparison. Thus, the choice of the comparator for any new treatment becomes a key issue, especially when there are great differences in medical practice and of use conditions of the comparators depending on the geographical zones and their evolution with time. The choice of the comparators must satisfy sometimes different expectations from the registration authorities and for insurance coverage. The universal comparator that allows answering all the clinical assessment questions does not exist. Placebo, when it can be used, remains a reference for the MA (marketing authorisation) application, but does not exclude the use of the reference drug available on the market and prescribed under optimal efficacy conditions. The reference treatment is sometimes a difficult choice due to the absence of validated therapeutic recommendations or if the recommendations vary depending on the countries. The expansion and international harmonization of prescription guidelines (clinical practice guidelines) would reinforce the robustness and efficiency of clinical research efforts with respect to the relevance of the comparison to reference treatments. This principle also applies to the use of a non-drug comparator when it has been recognized as the reference comparator in the treatment of the pathology in question. In as much as possible, the search for a consensus must also aim at defining in the clinical development recommendations significant thresholds for the size of evaluated effects. Optimization of the information made available after clinical trials could also be helped by the development of use of methodologies that allow assessing superiority on secondary criteria during a non-inferiority study on the main criterion. Finally, the development of early scientific consultations by the Haute Autorité de Santé (HAS, French Health Authority) would contribute to adapt phase III clinical trials better to questions concerning the assessment of the clinical added value of the medicinal products evaluated. © 2010 Société Française de Pharmacologie et de Thérapeutique.

2010-12-01

To determine the relationship between the plane of occlusion and the Camper's line (ala-tragus line). Lateral cephalograms of 105 dentulous subjects were obtained after outlining the tragus and the base of the ala of the nose with radiopaque markers. Tracings of the cephalograms were done and the relationship between the plane of occlusion and the Camper's line (ala-tragus line) was noted. The most common tragal reference as a posterior landmark for determination of plane of occlusion was found to be below inferior (in 30.48% of subjects), and inferior (in 24.76% of subjects). The least common tragal reference was found to be above superior (in 3.82% of subjects) followed by superior of tragus and the point between superior and middle of the tragus (in 6.66% of subjects). The tragal reference in this study population was more towards the inferior of the tragus, with most of the times being below the inferior border. Therefore, the orientation of the plane of occlusion using the superior of tragus as a posterior landmark (according to the widely accepted definition of Camper's line) may be considered to be questionable. Further, the use of the tragus as a posterior landmark for the orientation of the plane of occlusion may be questioned on the basis of the findings of this study.

George, Sanju; Haque, M Sayeed; Oyebode, Femi

2006-09-14

The outcome of assessments is determined by the standard-setting method used. There is a wide range of standard-setting methods and the two used most extensively in undergraduate medical education in the UK are the norm-reference and the criterion-reference methods. The aims of the study were to compare these two standard-setting methods for a multiple-choice question examination and to estimate the test-retest and inter-rater reliability of the modified Angoff method. The norm-reference method of standard-setting (mean minus 1 SD) was applied to the 'raw' scores of 78 4th-year medical students on a multiple-choice examination (MCQ). Two panels of raters also set the standard using the modified Angoff method for the same multiple-choice question paper on two occasions (6 months apart). We compared the pass/fail rates derived from the norm reference and the Angoff methods and also assessed the test-retest and inter-rater reliability of the modified Angoff method. The pass rate with the norm-reference method was 85% (66/78) and that by the Angoff method was 100% (78 out of 78). The percentage agreement between Angoff method and norm-reference was 78% (95% CI 69% - 87%). The modified Angoff method had an inter-rater reliability of 0.81-0.82 and a test-retest reliability of 0.59-0.74. There were significant differences in the outcomes of these two standard-setting methods, as shown by the difference in the proportion of candidates that passed and failed the assessment. The modified Angoff method was found to have good inter-rater reliability and moderate test-retest reliability.

On the intonation of German intonation questions: the role of the prenuclear region.

PubMed

Petrone, Caterina; Niebuhr, Oliver

2014-03-01

German questions and statements are distinguished not only by lexical and syntactic but also by intonational means. This study revisits, for Northern Standard German, how questions are signalled intonationally in utterances that have neither lexical nor syntactic cues. Starting from natural productions of such 'intonation questions', two perception experiments were run. Experiment 1 is based on a gating paradigm, which was applied to naturally produced questions and statements. Experiment 11 includes two indirect-identification tasks. Resynthesized stimuli were judged in relation to two context utterances, each of which was compatible with only one sentence mode interpretation. Results show that utterances with a finally falling nuclear pitch-accent contour can also trigger question perception. An utterance-final rise is not mandatory. Also, question and statement cues are not restricted to the intonational nucleus. Rather, listeners can refer to shape, slope, and alignment differences of the preceding prenuclear pitch accent to identify sentence mode. These findings are in line with studies suggesting that the utterance-final rise versus fall contrast is not directly related to sentence modality, but represents a separate attitudinal meaning dimension. Moreover, the findings support that both prenuclear and nuclear fundamental frequency (F0) patterns must be taken into account in the analysis of tune meaning.

Accuracy and artifact: reexamining the intensity bias in affective forecasting.

PubMed

Levine, Linda J; Lench, Heather C; Kaplan, Robin L; Safer, Martin A

2012-10-01

Research on affective forecasting shows that people have a robust tendency to overestimate the intensity of future emotion. We hypothesized that (a) people can accurately predict the intensity of their feelings about events and (b) a procedural artifact contributes to people's tendency to overestimate the intensity of their feelings in general. People may misinterpret the forecasting question as asking how they will feel about a focal event, but they are later asked to report their feelings in general without reference to that event. In the current investigation, participants predicted and reported both their feelings in general and their feelings about an election outcome (Study 1) and an exam grade (Study 3). We also assessed how participants interpreted forecasting questions (Studies 2 and 4) and conducted a meta-analysis of affective forecasting research (Study 5). The results showed that participants accurately predicted the intensity of their feelings about events. They overestimated only when asked to predict how they would feel in general and later report their feelings without reference to the focal event. Most participants, however, misinterpreted requests to predict their feelings in general as asking how they would feel when they were thinking about the focal event. Clarifying the meaning of the forecasting question significantly reduced overestimation. These findings reveal that people have more sophisticated self-knowledge than is commonly portrayed in the affective forecasting literature. Overestimation of future emotion is partly due to a procedure in which people predict one thing but are later asked to report another.

Why and How. The Future of the Central Questions of Consciousness

PubMed Central

Havlík, Marek; Kozáková, Eva; Horáček, Jiří

2017-01-01

In this review, we deal with two central questions of consciousness how and why, and we outline their possible future development. The question how refers to the empirical endeavor to reveal the neural correlates and mechanisms that form consciousness. On the other hand, the question why generally refers to the “hard problem” of consciousness, which claims that empirical science will always fail to provide a satisfactory answer to the question why is there conscious experience at all. Unfortunately, the hard problem of consciousness will probably never completely disappear because it will always have its most committed supporters. However, there is a good chance that its weight and importance will be highly reduced by empirically tackling consciousness in the near future. We expect that future empirical endeavor of consciousness will be based on a unifying brain theory and will answer the question as to what is the function of conscious experience, which will in turn replace the implications of the hard problem. The candidate of such a unifying brain theory is predictive coding, which will have to explain both perceptual consciousness and conscious mind-wandering in order to become the truly unifying theory of brain functioning.

Abstract In the course of our supervisory work over the years, we have noticed that qualitative research tends to evoke a lot of questions and worries, so-called frequently asked questions (FAQs). This series of four articles intends to provide novice researchers with practical guidance for conducting high-quality qualitative research in primary care. By ‘novice’ we mean Master’s students and junior researchers, as well as experienced quantitative researchers who are engaging in qualitative research for the first time. This series addresses their questions and provides researchers, readers, reviewers and editors with references to criteria and tools for judging the quality of qualitative research papers. The second article focused on context, research questions and designs, and referred to publications for further reading. This third article addresses FAQs about sampling, data collection and analysis. The data collection plan needs to be broadly defined and open at first, and become flexible during data collection. Sampling strategies should be chosen in such a way that they yield rich information and are consistent with the methodological approach used. Data saturation determines sample size and will be different for each study. The most commonly used data collection methods are participant observation, face-to-face in-depth interviews and focus group discussions. Analyses in ethnographic, phenomenological, grounded theory, and content analysis studies yield different narrative findings: a detailed description of a culture, the essence of the lived experience, a theory, and a descriptive summary, respectively.

The ARIANE5 On Board Computer (OBC) and Inertial Reference System (SRI) are based on Motorola MC68020 processor and MC68882 coprocessor. The SRI data acquisition board also uses the DSP TMS320C25 from Texas Instruments. These devices were characterized to proton induced SEUs. But representativeness of SEU test results on processors was questioned during ARIANE5 studies. Protons test of these devices were also performed in the actual equipments with flight (or representative of) softwares. The results show that the On Board Computer and the Inertial Reference System can satisfy the requirements of the ARIANE5 missions.

Comparing Students' and Experts' Understanding of the Content of a Lecture

NASA Astrophysics Data System (ADS)

Hrepic, Zdeslav; Zollman, Dean A.; Sanjay Rebello, N.

2007-06-01

In spite of advances in physics pedagogy, the lecture is by far the most widely used format of instruction. We investigated students' understanding and perceptions of the content delivered during a physics lecture. A group of experts (physics instructors) also participated in the study as a reference for the comparison. During the study, all participants responded to a written conceptual survey on sound propagation. Next, they looked for answers to the survey questions in a videotaped lecture by a nationally known teacher. As they viewed the lecture, they indicated instances, if any, in which the survey questions were answered during the lecture. They also wrote down (and if needed, later explained) the answer, which they perceived was given by the instructor in the video lecture. Students who participated in the study were enrolled in a conceptual physics course and had already covered the topic in class before the study. We discuss and compare students' and experts' responses to the survey questions before and after the lecture.

Measurement of breastfeeding initiation: Ethiopian mothers' perception about survey questions assessing early initiation of breastfeeding.

PubMed

Salasibew, Mihretab Melesse; Filteau, Suzanne; Marchant, Tanya

2014-01-01

Although breastfeeding is almost universal in Ethiopia, only 52% newborns benefited from early initiation in 2011. Early initiation is one of the recommended interventions for saving newborn lives but its potential seems not yet realized for Ethiopian newborns and there is a need for continued efforts to increase coverage. To do so, it is also relevant to focus on consistent and accurate reporting of coverage in early initiation. WHO recommends the question "how long after birth did you first put [name] to the breast?" in order to assess coverage in early initiation. It is designed to measure the time after birth when the mother attempted to initiate breastfeeding regardless of whether breast milk had arrived or not. However, it is unclear how mothers perceive this question and what their responses of time refer to. In this study, we assessed Ethiopian mothers' perception about the question assessing early initiation. Cognitive interviews were conducted between April and May 2013 with eligible mothers in Basona and Debrebirhan woredas (districts), 120 km away from Addis Ababa, Ethiopia. A total of 49 mothers, most from Basona (n = 36) and the rest from Debrebirhan woredas (n = 13) were interviewed. No probes or follow on questions were required for mothers to understand what the WHO recommended question was about. However, further probing was needed to ascertain what maternal responses of time refer to. Accordingly, mothers' response about the timing of early initiation was related to the first time the newborn received breast milk rather than their first attempt to initiate breastfeeding. In addition, considerable probing was required to approximate and code responses of time based on the WHO coding format because some mothers were unable to assess time in minutes or hours. The existing question is not adequate to identify intended attempts of mothers to initiate breastfeeding. We recommend revising the question as "how long after birth did you first put [name] to the breast even if your breast milk did not arrive yet?" Standard probes or follow on questions are required to avoid subjective interpretation of the indicator.

Violations of information structure: an electrophysiological study of answers to wh-questions.

Cowles, H W; Kluender, Robert; Kutas, Marta; Polinsky, Maria

2007-09-01

This study investigates brain responses to violations of information structure in wh-question-answer pairs, with particular emphasis on violations of focus assignment in it-clefts (It was the queen that silenced the banker). Two types of ERP responses in answers to wh-questions were found. First, all words in the focus-marking (cleft) position elicited a large positivity (P3b) characteristic of sentence-final constituents, as did the final words of these sentences, which suggests that focused elements may trigger integration effects like those seen at sentence end. Second, the focusing of an inappropriate referent elicited a smaller, N400-like effect. The results show that comprehenders actively use structural focus cues and discourse-level restrictions during online sentence processing. These results, based on visual stimuli, were different from the brain response to auditory focus violations indicated by pitch-accent [Hruska, C., Steinhauer, K., Alter, K., & Steube, A. (2000).

Deltete, D.; Fisher, S.; Kelly, J.J.

1994-05-01

EPRI began, late in 1987, to produce a Radwaste Desk Reference that would allow each of the member utilities access to the available information and expertise on radwaste management. EPRI considers this important because radwaste management involves a wide variety of scientific and engineering disciplines. These include chemical and mechanical engineering, chemistry, and health physics. Radwaste management also plays a role in implementing a wide variety of regulatory requirements. These include plant-specific technical specifications, NRC standards for protection against radiation, DOE transportation regulations and major environmental legislation such as the Resource Conservation and Recovery Act. EPRI chose a question andmore » answer format because it could be easily accessed by radwaste professionals with a variety of interests. The questions were generated at two meetings of utility radwaste professionals and EPRI contractors. The names of the participants and their affiliation appear in the acknowledgments. The questions were organized using the matrix which appears in the introduction and below. During the writing phase, some questions were combined and new questions added. To aid the reader, each question was numbered and tied to individual Section Contents. An extensive index provides additional reader assistance. EPRI chose authors who are acknowledged experts in their fields and good communicators. Each author focused her or his energies on specific areas of radwaste management activities, thereby contributing to one or more volumes of the Radwaste Desk Reference. Volume 1, which is already in publication, addresses dry active waste generation, processing and measurement. Volume 2 addresses low level waste storage, transportation and disposal. This volume, Volume 3, is being issued in two parts. Part 1 concentrates on the processing of liquid radioactive waste, whereas Part 2 addresses liquid waste management.« less

The conception and evaluation of standardized oral or written questioning as quantifying instruments of research orientate by the basic premises of Marxist-Leninist theory of recognition and general scientific logic. In the present contribution the socio-gerontological research process is outlined in extracts. By referring to the intrinsic connection between some of its essential components--problem, formation of hypotheses, obtaining indicators/measurement, preliminary examination, evaluation-as well as to typical errors and (fictitious) examples of practical research, this contribution contrasts the natural, apparently uncomplicated course of structured questioning with its qualitative methodological fundamentals and demands.

Reference View Selection in DIBR-Based Multiview Coding.

Augmented reality, interactive navigation in 3D scenes, multiview video, and other emerging multimedia applications require large sets of images, hence larger data volumes and increased resources compared with traditional video services. The significant increase in the number of images in multiview systems leads to new challenging problems in data representation and data transmission to provide high quality of experience on resource-constrained environments. In order to reduce the size of the data, different multiview video compression strategies have been proposed recently. Most of them use the concept of reference or key views that are used to estimate other images when there is high correlation in the data set. In such coding schemes, the two following questions become fundamental: 1) how many reference views have to be chosen for keeping a good reconstruction quality under coding cost constraints? And 2) where to place these key views in the multiview data set? As these questions are largely overlooked in the literature, we study the reference view selection problem and propose an algorithm for the optimal selection of reference views in multiview coding systems. Based on a novel metric that measures the similarity between the views, we formulate an optimization problem for the positioning of the reference views, such that both the distortion of the view reconstruction and the coding rate cost are minimized. We solve this new problem with a shortest path algorithm that determines both the optimal number of reference views and their positions in the image set. We experimentally validate our solution in a practical multiview distributed coding system and in the standardized 3D-HEVC multiview coding scheme. We show that considering the 3D scene geometry in the reference view, positioning problem brings significant rate-distortion improvements and outperforms the traditional coding strategy that simply selects key frames based on the distance between cameras.

Evaluating imbalances of adverse events during biosimilar development

ABSTRACT Biosimilars are designed to be highly similar to approved or licensed (reference) biologics and are evaluated based on the totality of evidence from extensive analytical, nonclinical and clinical studies. As part of the stepwise approach recommended by regulatory agencies, the first step in the clinical evaluation of biosimilarity is to conduct a pharmacokinetics similarity study in which the potential biosimilar is compared with the reference product. In the context of biosimilar development, a pharmacokinetics similarity study is not necessarily designed for a comparative assessment of safety. Development of PF-05280014, a potential biosimilar to trastuzumab, illustrates how a numerical imbalance in an adverse event in a small pharmacokinetics study can raise questions on safety that may require additional clinical trials.

Recent advances in smartphone technology now allow clinicians to use commercially produced applications when studying for nursing certification examinations. The quality of currently available CCRN review applications varies in this first generation of products. Most are limited to multiple-choice practice questions, although a few have additional elements such as study guides and reference charts. Weaknesses found in the applications evaluated include poorly written and edited content, questions limited to rote memorization rather than application and analysis of knowledge, and content too basic or outside the scope of experienced critical care nursing practice.

Does movement influence representations of time and space?

PubMed Central

2017-01-01

Embodied cognition posits that abstract conceptual knowledge such as mental representations of time and space are at least partially grounded in sensorimotor experiences. If true, then the execution of whole-body movements should result in modulations of temporal and spatial reference frames. To scrutinize this hypothesis, in two experiments participants either walked forward, backward or stood on a treadmill and responded either to an ambiguous temporal question (Experiment 1) or an ambiguous spatial question (Experiment 2) at the end of the walking manipulation. Results confirmed the ambiguousness of the questions in the control condition. Nevertheless, despite large power, walking forward or backward did not influence the answers or response times to the temporal (Experiment 1) or spatial (Experiment 2) question. A follow-up Experiment 3 indicated that this is also true for walking actively (or passively) in free space (as opposed to a treadmill). We explore possible reasons for the null-finding as concerns the modulation of temporal and spatial reference frames by movements and we critically discuss the methodological and theoretical implications.

2013-09-01

When evaluating assessments, the impact on learning is often overlooked. Approaches to learning can be deep, surface and strategic. To provide insights into exam quality, we investigated the learning approaches taken by trainees preparing for the Australian and New Zealand College of Anaesthetists (ANZCA) Final Exam. The revised two-factor Study Process Questionnaire (R-SPQ-2F) was modified and validated for this context and was administered to ANZCA advanced trainees. Additional questions were asked about perceived value for anaesthetic practice, study time and approaches to learning for each exam component. Overall, 236 of 690 trainees responded (34%). Responses indicated both deep and surface approaches to learning with a clear preponderance of deep approaches. The anaesthetic viva was valued most highly and the multiple choice question component the least. Despite this, respondents spent the most time studying for the multiple choice questions. The traditionally low short answer questions pass rate could not be explained by limited study time, perceived lack of value or study approaches. Written responses suggested that preparation for multiple choice questions was characterised by a surface approach, with rote memorisation of past questions. Minimal reference was made to the ANZCA syllabus as a guide for learning. These findings indicate that, although trainees found the exam generally relevant to practice and adopted predominantly deep learning approaches, there was considerable variation between the four components. These results provide data with which to review the existing ANZCA Final Exam and comparative data for future studies of the revisions to the ANZCA curriculum and exam process.

Algorithmic, LOCS and HOCS (chemistry) exam questions: performance and attitudes of college students

2002-02-01

The performance of freshmen biology and physics-mathematics majors and chemistry majors as well as pre- and in-service chemistry teachers in two Israeli universities on algorithmic (ALG), lower-order cognitive skills (LOCS), and higher-order cognitive skills (HOCS) chemistry exam questions were studied. The driving force for the study was an interest in moving science and chemistry instruction from an algorithmic and factual recall orientation dominated by LOCS, to a decision-making, problem-solving and critical system thinking approach, dominated by HOCS. College students' responses to the specially designed ALG, LOCS and HOCS chemistry exam questions were scored and analysed for differences and correlation between the performance means within and across universities by the questions' category. This was followed by a combined student interview - 'speaking aloud' problem solving session for assessing the thinking processes involved in solving these types of questions and the students' attitudes towards them. The main findings were: (1) students in both universities performed consistently in each of the three categories in the order of ALG > LOCS > HOCS; their 'ideological' preference, was HOCS > algorithmic/LOCS, - referred to as 'computational questions', but their pragmatic preference was the reverse; (2) success on algorithmic/LOCS does not imply success on HOCS questions; algorithmic questions constitute a category on its own as far as students success in solving them is concerned. Our study and its results support the effort being made, worldwide, to integrate HOCS-fostering teaching and assessment strategies and, to develop HOCS-oriented science-technology-environment-society (STES)-type curricula within science and chemistry education.

Is victim identity in genocide a question of science or law? The scientific perspective, with special reference to Darfur.

PubMed

Komar, Debra

2008-09-01

In genocide, victims must represent an ethnic, racial, religious or national group. But is victim identity a question of science or law? Must victims be a socially recognized group or can group identity exist solely in the mind of the perpetrator? This question is relevant to the on-going crisis in Darfur. The "Arab-on-African" violence depicted in the media encompasses identities not shared by Darfurians. This study details an evaluation of victim identity in Darfur, based on field research and literature review. Darfurians are defined by subsistence strategy and economic groups are not protected under genocide law. Whether Darfur is genocide depends on whether victims must conform to scientific group classifications or need only be defined by their relationship to the perpetrators.

To assess a question-answer pair (QAP) database integrated with websites developed for drug information centres to answer complex questions effectively. Descriptive study with comparison of two subsequent 6-year periods (1995-2000 and 2001-2006). The Regional Medicines Information and Pharmacovigilance Centres in Norway (RELIS). A randomised sample of QAPs from the RELIS database. Answer time in days compared with Mann-Whitney U test. Number of drugs involved (one, two, three or more), complexity (judgemental and/or patient-related or not) and literature search (none, simple or advanced) compared with χ(2) tests. 842 QAPs (312 from 1995 to 2000 and 530 from 2001 to 2006) were compared. The fraction of judgemental and patient-related questions increased (66%-75% and 54%-72%, respectively, p<0.01). Number of drugs and literature search (>50% advanced) was similar in the two periods, but the fraction of answers referring to the RELIS database increased (13%-31%, p<0.01). Median answer time was reduced from 2 days to 1 (p<0.01), although the fraction of complex questions increased from the first to the second period. Furthermore, the mean number of questions per employee per year increased from 66 to 89 from the first to the second period. The authors conclude that RELIS has a potential to efficiently answer complex questions. The model is of relevance for organisation of drug information centres.

Radiology reports are the major, and often only, means of communication between radiologists and their referring clinicians. The purposes of this study are to identify referring physicians' preferences about radiology reports and to quantify their perceived value of multimedia reports (with embedded images) compared with narrative text reports. We contacted 1800 attending physicians from a range of specialties at large tertiary care medical center via e-mail and a hospital newsletter linking to a 24-question electronic survey between July and November 2012. One hundred sixty physicians responded, yielding a response rate of 8.9%. Survey results were analyzed using Statistical Analysis Software (SAS Institute Inc, Cary, NC). Of the 160 referring physicians respondents, 142 (89%) indicated a general interest in reports with embedded images and completed the remainder of the survey questions. Of 142 respondents, 103 (73%) agreed or strongly agreed that reports with embedded images could improve the quality of interactions with radiologists; 129 respondents (91%) agreed or strongly agreed that having access to significant images enhances understanding of a text-based report; 110 respondents (77%) agreed or strongly agreed that multimedia reports would significantly improve referring physician satisfaction; and 85 respondents (60%) felt strongly or very strongly that multimedia reports would significantly improve patient care and outcomes. Creating accessible, readable, and automatic multimedia reports should be a high priority to enhance the practice and satisfaction of referring physicians, improve patient care, and emphasize the critical role radiology plays in current medical care.

The one number you need to grow.

PubMed

Reichheld, Frederick F

2003-12-01

Companies spend lots of time and money on complex tools to assess customer satisfaction. But they're measuring the wrong thing. The best predictor of top-line growth can usually be captured in a single survey question: Would you recommend this company to a friend? This finding is based on two years of research in which a variety of survey questions were tested by linking the responses with actual customer behavior--purchasing patterns and referrals--and ultimately with company growth. Surprisingly, the most effective question wasn't about customer satisfaction or even loyalty per se. In most of the industries studied, the percentage of customers enthusiastic enough about a company to refer it to a friend or colleague directly correlated with growth rates among competitors. Willingness to talk up a company or product to friends, family, and colleagues is one of the best indicators of loyalty because of the customer's sacrifice in making the recommendation. When customers act as references, they do more than indicate they've received good economic value from a company; they put their own reputations on the line. And they will risk their reputations only if they feel intense loyalty. The findings point to a new, simpler approach to customer research, one directly linked to a company's results. By substituting a single question--blunt tool though it may appear to be--for the complex black box of the customer satisfaction survey, companies can actually put consumer survey results to use and focus employees on the task of stimulating growth.

Backtracking Depth-Resolved Microstructures for Crystal Plasticity Identification—Part 1: Backtracking Microstructures

NASA Astrophysics Data System (ADS)

Shi, Qiwei; Latourte, Félix; Hild, François; Roux, Stéphane

2017-12-01

In situ mechanical tests performed on polycrystalline materials in a scanning electron microscope suffer from the lack of information on depth-resolved three-dimensional microstructures. The latter ones can be accessed with focused ion beam technology only postmortem, because it is destructive. The present study considers the challenge of backtracking this deformed microstructure to the reference state. This theoretical question is tackled on a numerical (synthetic) test case. A two-dimensional microstructure with one dimension along the depth is considered, and deformed using a crystal plasticity law. The proposed numerical strategy is shown to retrieve accurately the reference state.

Recruiting Human Microbiome Shotgun Data to Site-Specific Reference Genomes

Xie, Gary; Lo, Chien-Chi; Scholz, Matthew; Chain, Patrick S. G.

2014-01-01

The human body consists of innumerable multifaceted environments that predispose colonization by a number of distinct microbial communities, which play fundamental roles in human health and disease. In addition to community surveys and shotgun metagenomes that seek to explore the composition and diversity of these microbiomes, there are significant efforts to sequence reference microbial genomes from many body sites of healthy adults. To illustrate the utility of reference genomes when studying more complex metagenomes, we present a reference-based analysis of sequence reads generated from 55 shotgun metagenomes, selected from 5 major body sites, including 16 sub-sites. Interestingly, between 13% and 92% (62.3% average) of these shotgun reads were aligned to a then-complete list of 2780 reference genomes, including 1583 references for the human microbiome. However, no reference genome was universally found in all body sites. For any given metagenome, the body site-specific reference genomes, derived from the same body site as the sample, accounted for an average of 58.8% of the mapped reads. While different body sites did differ in abundant genera, proximal or symmetrical body sites were found to be most similar to one another. The extent of variation observed, both between individuals sampled within the same microenvironment, or at the same site within the same individual over time, calls into question comparative studies across individuals even if sampled at the same body site. This study illustrates the high utility of reference genomes and the need for further site-specific reference microbial genome sequencing, even within the already well-sampled human microbiome.

A characterization of clinical questions asked by rehabilitation therapists.

PubMed

Kloda, Lorie Andrea; Bartlett, Joan C

2014-04-01

This study explored the information needs of rehabilitation therapists (occupational therapists, physical therapists, and speech-language pathologists) working with patients who have had strokes in order to characterize their clinical questions, defined as their formalized information needs arising in the context of everyday clinical practice. The researchers took a constructivist, interpretive approach, in which fifteen rehabilitation therapists working in various settings were recruited. Data were gathered using diaries, followed by diary-guided interviews, and thematically analyzed using template analysis. Rehabilitation therapists' clinical questions were characterized as having one or more of twelve foci and containing one or more of eight possible structural elements. Findings demonstrate that the evidence-based practice framework currently applied for questions relating to rehabilitation is inadequate for representing rehabilitation therapists' clinical questions. A new framework that is more comprehensive and descriptive is proposed. Librarians working with students and clinicians in rehabilitation can employ knowledge of the twelve foci and the question structure for rehabilitation to guide the reference interview. Instruction on question formulation in evidence-based practice can employ the revised structure for rehabilitation, offering students and clinicians an alternative to the traditional patient, intervention, comparison, outcome (PICO) structure. Information products, including bibliographic databases and synopsis services, can tailor their interfaces according to question foci and prompt users to enter search terms corresponding to any of the eight possible elements found in rehabilitation therapists' clinical questions.

It’s More Than Stamp Collecting: How Genome Sequencing Can Unify Biological Research

PubMed Central

Richards, Stephen

2015-01-01

The availability of reference genome sequences, especially the human reference, has revolutionized the study of biology. However, whilst the genomes of some species have been fully sequenced, a wide range of biological problems still cannot be effectively studied for lack of genome sequence information. Here, I identify neglected areas of biology and describe how both targeted species sequencing and more broad taxonomic surveys of the tree of life can address important biological questions. I enumerate the significant benefits that would accrue from sequencing a broader range of taxa, as well as discuss the technical advances in sequencing and assembly methods that would allow for wide-ranging application of whole-genome analysis. Finally, I suggest that in addition to “Big Science” survey initiatives to sequence the tree of life, a modified infrastructure-funding paradigm would better support reference genome sequence generation for research communities most in need.

Low Levels of Evidence on the Plastic Surgery In-Service Training Exam.

PubMed

Silvestre, Jason; Bilici, Nadir; Serletti, Joseph M; Chang, Benjamin

2016-06-01

The Plastic Surgery In-Service Training Exam is written by the American Society of Plastic Surgeons. Examinees reasonably infer that tested material reflects the Society's vision for the core curriculum in plastic surgery. The purpose of this study was to determine the levels of evidence on which credited answers to the examination questions are based. Two recent Plastic Surgery In-Service Training Exams (2014 and 2015) were analyzed. Questions were categorized using a taxonomy model. Recommended journal article references for Level III (decision-making) questions were assigned a level of evidence. Exam sections were analyzed for differences in question taxonomy distribution and level of evidence. To look for studies with higher levels of evidence, a PubMed search was conducted for a random sample of 10 questions from each section. One hundred three Level I (25.8 percent), 138 Level II (34.5 percent), and 159 Level III (39.8 percent) questions were analyzed (p < 0.001). The hand and lower extremity section had the highest percentage of Level III questions (50.0 percent; p = 0.005). Journal articles had a mean level of evidence of 3.9 ± 0.7. The number of articles with a low level of evidence (IV and V) (p = 0.624) and the percentage of questions supported by articles with a high level of evidence (I and II) (p = 0.406) did not vary by section. The PubMed search revealed no instances of a higher level of evidence than the recommended reading list. A significant percentage of Plastic Surgery In-Service Training Exam questions test clinical management, but most are supported with a low level of evidence. Although that is consistent with low level of evidence of plastic surgery literature, educators should recognize the potential for biases of question writers.

In your face: transcendence in embodied interaction

PubMed Central

Gallagher, Shaun

2014-01-01

In cognitive psychology, studies concerning the face tend to focus on questions about face recognition, theory of mind (ToM) and empathy. Questions about the face, however, also fit into a very different set of issues that are central to ethics. Based especially on the work of Levinas, philosophers have come to see that reference to the face of another person can anchor conceptions of moral responsibility and ethical demand. Levinas points to a certain irreducibility and transcendence implicit in the face of the other. In this paper I argue that the notion of transcendence involved in this kind of analysis can be given a naturalistic interpretation by drawing on recent interactive approaches to social cognition found in developmental psychology, phenomenology, and the study of autism.

How Much Nutrition for How Much Growth?
.

PubMed

Hermanussen, Michael; Wit, Jan M

2017-01-01

Increasing agreement exists about the use of length-for-age as the indicator of choice in monitoring the long-term impact of chronic nutritional deficiency. Yet, already shortly after World War I, a causal link between nutrition and growth was questioned. Also, modern meta-analyses of controlled nutrition intervention studies show that the net effect of nutrition on body height is small. Broad evidence obtained from historic observations on human starvation made since the 19th century questions an obligatory association between nutrition and growth. Many additional explanations for the apparent shortness of people from developing countries have been published since, focusing on genetic factors, environment, economy, epigenetics, and, recently, psychosocial factors, such as strategic growth adjustments suggesting stature to be a social signal. The marked variability in average population height of up to 20 cm within a few generations complicates the use of normative growth charts, even though they have been widely propagated. We support the concept of local growth references, for example using the "Synthetic Growth References" methodology. These references combine local growth information obtained from a given population of interest and common features of human population growth, with LMS values for height, weight, and BMI from birth to maturity.

Conversational assessment in memory clinic encounters: interactional profiling for differentiating dementia from functional memory disorders.

PubMed

Jones, Danielle; Drew, Paul; Elsey, Christopher; Blackburn, Daniel; Wakefield, Sarah; Harkness, Kirsty; Reuber, Markus

2016-01-01

In the UK dementia is under-diagnosed, there is limited access to specialist memory clinics, and many of the patients referred to such clinics are ultimately found to have functional (non-progressive) memory disorders (FMD), rather than a neurodegenerative disorder. Government initiatives on 'timely diagnosis' aim to improve the rate and quality of diagnosis for those with dementia. This study seeks to improve the screening and diagnostic process by analysing communication between clinicians and patients during initial specialist clinic visits. Establishing differential conversational profiles could help the timely differential diagnosis of memory complaints. This study is based on video- and audio recordings of 25 initial consultations between neurologists and patients referred to a UK memory clinic. Conversation analysis was used to explore recurrent communicative practices associated with each diagnostic group. Two discrete conversational profiles began to emerge, to help differentiate between patients with dementia and functional memory complaints, based on (1) whether the patient is able to answer questions about personal information; (2) whether they can display working memory in interaction; (3) whether they are able to respond to compound questions; (4) the time taken to respond to questions; and (5) the level of detail they offer when providing an account of their memory failure experiences. The distinctive conversational profiles observed in patients with functional memory complaints on the one hand and neurodegenerative memory conditions on the other suggest that conversational profiling can support the differential diagnosis of functional and neurodegenerative memory disorders.

Information intervention in the pharmaceutical sciences.

Chatfield, Amy J; Romero, Rebecca M; Haworth, Ian S

2012-01-01

Professional guidelines state that higher-order thinking skills are a desirable outcome of pharmacy education. In this context, courses in pharmaceutics at the University of Southern California are taught in a learner-centered manner that requires use of chemical reference sources and interpretation of physicochemical information for drug molecules. To facilitate these activities, a librarian worked with faculty to design a class on reference sources and primary literature. Students believed the librarian instruction was beneficial. After the intervention, faculty fielded fewer information-related questions and the librarian received more sophisticated questions. The class emphasizes the importance of collaboration between librarians and faculty in achieving these results.

Silvestre, Jason; Chang, Benjamin; Serletti, Joseph M

2016-01-01

To facilitate knowledge acquisition during plastic surgery residency, we analyzed the breast curriculum on the Plastic Surgery In-Service Training Exam (PSITE). Breast-related questions on 6 consecutive PSITEs were analyzed (2008-2013). Topics were categorized by the content outline for the American Board of Plastic Surgery written board examination. Question vignettes were classified by taxonomy and clinical setting. References for correct answer choices were categorized by source and publication lag. A total of 136 breast-related questions were analyzed (136/1174, 12%). Questions tended to appear more in the Breast and Cosmetic (75%) section than the Comprehensive (25%) section (p < 0.001). Most question vignettes were written in a clinical setting (64%, p < 0.001). Question taxonomy was evenly distributed among recall (34%), interpretation (28%), and decision-making (37%, p > 0.05). Only 6% of questions required photographic evaluation. Breast-related topics focused on esthetic problems (35%), traumatic deformities (22%), and tumors (21%). Answer references comprised 293 citations to 63 unique journals published a median of 6 years before PSITE administration. Plastic and Reconstructive Surgery (57%) was the most cited journal (p < 0.001) and Surgery of the Breast: Principles and Art by Spear was the most referenced textbook (22%). The PSITE affords a curriculum that reflects breast-related topics on the American Board of Plastic Surgery written board examination. These data may optimize knowledge acquisition in esthetic and reconstructive breast surgery. Copyright © 2015. Published by Elsevier Inc.

2016-11-01

Background The availability of clinical information and a pertinent clinical question can improve the diagnostic accuracy of the imaging process. Purpose To examine if an electronic request form forcing referring clinicians to provide separate input of both clinical information and a clinical question can improve the quality of the request. Material and Methods A total of 607 request forms in the clinical worklists for a computed tomography (CT) scan of the thorax, the abdomen or their combination, were examined. Using software of our own making, we examined the presence of clinical information and a clinical question before and after the introduction of a new, more compelling order method. We scored and compared the quality of the clinical information and the clinical question between the two systems and we examined the effect on productivity. Results Both clinical information and a clinical question were present in 76.7% of cases under the old system and in 95.3% under the new system ( P < 0.001). Individual characteristics of the clinical information and the clinical question however, with the exception of incompleteness, showed little improvement under the new system. There was also no significant difference between the two systems in the number of requests requiring further search. Conclusion The introduction of electronic radiology request forms compelling referring clinicians to provide separate input of clinical information and a clinical question provides only limited benefit to the quality of the request. Raising awareness among clinicians of the importance of a well-written request remains essential.

Explanation, motivation and question posing routines in university mathematics teachers' pedagogical discourse: a commognitive analysis

NASA Astrophysics Data System (ADS)

Viirman, Olov

2015-11-01

This paper investigates the teaching practices used by university mathematics teachers when lecturing, a topic within university mathematics education research which is gaining an increasing interest. In the study, a view of mathematics teaching as a discursive practice is taken, and Sfard's commognitive framework is used to investigate the teaching practices of seven Swedish university mathematics teachers on the topic of functions. The present paper looks at the discourse of mathematics teaching, presenting a categorization of the didactical routines into three categories - explanation, motivation and question posing routines. All of these are present in the discourses of all seven teachers, but within these general categories, a number of different sub-categories of routines are found, used in different ways and to different extent by the various teachers. The explanation routines include known mathematical facts, summary and repetition, different representations, everyday language, and concretization and metaphor; the motivation routines include reference to utility, the nature of mathematics, humour and result focus; and the question posing routines include control questions, asking for facts, enquiries and rhetorical questions. This categorization of question posing routines, for instance, complements those already found in the literature. In addition to providing a valuable insight into the teaching of functions at the university level, the categorizations presented in the study can also be useful for investigating the teaching of other mathematical topics.

Two layers LSTM with attention for multi-choice question answering in exams

NASA Astrophysics Data System (ADS)

Li, Yongbin

2018-03-01

Question Answering in Exams is typical question answering task that aims to test how accurately the model could answer the questions in exams. In this paper, we use general deep learning model to solve the multi-choice question answering task. Our approach is to build distributed word embedding of question and answers instead of manually extracting features or linguistic tools, meanwhile, for improving the accuracy, the external corpus is introduced. The framework uses a two layers LSTM with attention which get a significant result. By contrast, we introduce the simple long short-term memory (QA-LSTM) model and QA-LSTM-CNN model and QA-LSTM with attention model as the reference. Experiment demonstrate superior performance of two layers LSTM with attention compared to other models in question answering task.

Series: Practical guidance to qualitative research. Part 2: Context, research questions and designs.

PubMed

Korstjens, Irene; Moser, Albine

2017-12-01

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

Sleep and sleepiness in environmental intolerances: a population-based study.

PubMed

Nordin, Maria; Nordin, Steven

2016-08-01

About one fourth of the general population report environmental intolerance (EI) to odorous/pungent chemicals, certain buildings, electromagnetic fields (EMFs), and/or sounds. EI sufferers show various clinical features, of which sleep disturbance is one. Sleep disturbance is common also in the general population, but it is not known whether the disturbance is more prominent in EI sufferers than in individuals who do not experience EI. Therefore, EI was compared on various sleep aspects with referents without EI. A population-based sample of 3406 individuals, aged 18-79 years, was recruited from Northern Sweden. Sleep quality, non-restorative sleep, daytime sleepiness, obstructive breathing, and nocturnal insomnia were assessed with the Karolinska Sleep Questionnaire. Single questions assessed time slept, amount of hours of needed sleep, and extent of enough time slept. All four EI groups, compared to the referents, reported significantly poorer sleep quality, more non-restorative sleep, more daytime sleepiness, more obstructive breathing and higher prevalence of nocturnal insomnia than the referents. Nocturnal insomnia was an important factor for EI groups attributing their most prevalent symptoms to chemicals and sounds, irrespective of distress and certain syndromes. None of the EI groups differed significantly from the referents on time slept, but reported needing more sleep time (the EMF-intolerance group showing only a tendency), and all four groups reported to perceive enough sleep to a significantly lesser extent. Sleep disturbance and daytime sleepiness are more common in individuals reporting EI compared to normal referents. Moreover, nocturnal insomnia is an important symptom in its own right in various types of EI. This evokes the question of whether or not sleep therapy may attenuate the severity of the EI.

Diagnostic value of different adherence measures using electronic monitoring and virologic failure as reference standards.

Deschamps, Ann E; De Geest, Sabina; Vandamme, Anne-Mieke; Bobbaers, Herman; Peetermans, Willy E; Van Wijngaerden, Eric

2008-09-01

Nonadherence to antiretroviral therapy is a substantial problem in HIV and jeopardizes the success of treatment. Accurate measurement of nonadherence is therefore imperative for good clinical management but no gold standard has been agreed on yet. In a single-center prospective study nonadherence was assessed by electronic monitoring: percentage of doses missed and drug holidays and by three self reports: (1) a visual analogue scale (VAS): percentage of overall doses taken; (2) the Swiss HIV Cohort Study Adherence Questionnaire (SHCS-AQ): percentage of overall doses missed and drug holidays and (3) the European HIV Treatment Questionnaire (EHTQ): percentage of doses missed and drug holidays for each antiretroviral drug separately. Virologic failure prospectively assessed during 1 year, and electronic monitoring were used as reference standards. Using virologic failure as reference standard, the best results were for (1) the SHCS-AQ after electronic monitoring (sensitivity, 87.5%; specificity, 78.6%); (2) electronic monitoring (sensitivity, 75%; specificity, 85.6%), and (3) the VAS combined with the SHCS-AQ before electronic monitoring (sensitivity, 87.5%; specificity, 58.6%). The sensitivity of the complex EHTQ was less than 50%. Asking simple questions about doses taken or missed is more sensitive than complex questioning about each drug separately. Combining the VAS with the SHCS-AQ seems a feasible nonadherence measure for daily clinical practice. Self-reports perform better after electronic monitoring: their diagnostic value could be lower when given independently.

Data mining the EXFOR database

Brown, David A.; Hirdt, John; Herman, Michal

2013-12-13

The EXFOR database contains the largest collection of experimental nuclear reaction data available as well as this data's bibliographic information and experimental details. We created an undirected graph from the EXFOR datasets with graph nodes representing single observables and graph links representing the connections of various types between these observables. This graph is an abstract representation of the connections in EXFOR, similar to graphs of social networks, authorship networks, etc. Analysing this abstract graph, we are able to address very specific questions such as 1) what observables are being used as reference measurements by the experimental community? 2) are thesemore » observables given the attention needed by various standards organisations? 3) are there classes of observables that are not connected to these reference measurements? In addressing these questions, we propose several (mostly cross section) observables that should be evaluated and made into reaction reference standards.« less

Phase change references for in-flight recalibration of orbital thermometry

NASA Astrophysics Data System (ADS)

Topham, T. S.; Latvakoski, H.; Watson, M.

2013-09-01

Several critical questions need to be answered to determine the potential utility of phase change materials as long-term orbital references: How accurate and repeatable will phase change reference implementations be after incorporating necessary design trade-offs to accommodate launch and the space environment? How can the temperature of phase transitions be transferred to something useful for calibration such as a black body. How, if at all, will the microgravity environment affect the phase transitions? To help answer some of these questions, three experiments will be conducted on the International Space Station (ISS). The experiments will test melts and freezes of three different phase change materials in various containment apparatus. This paper addresses the current status of the ISS experiments, as well as results from ground testing of several concepts for space application of PCM recalibration systems in the CORSAIR (Calibration Observations of Radiance Spectra in the far Infrared) black body.

2017-11-02

The objective of this study was to assess the validity of two questions about the perception of intensity of exposure to secondhand smoke (SHS) at home using as a reference environmental markers (airborne nicotine and benzene) and biomarkers of exposure (cotinine in saliva and urine). This was a cross-sectional study in a convenience sample of 49 non-smoking volunteers. We found a high correlation between self-reported SHS exposure and airborne nicotine (r sp =0.806, p<0.05), salivary cotinine (r sp =0.752, p<0.05), and urinary cotinine (r sp =0.626, p<0.05). We did not find differences between the score question and the conventional ones (p >0.05). In conclusion, the significant correlation of the two questions proposed with environmental markers and personal markers indicates their potential validity to assess exposure to SHS at home.

Roland Granqvist's main concern with our study is that it did not include more specific questions about the causes and severity of global warming. In fact, our Eos article presented a snapshot of the full study [Kendall Zimmerman, 2008] in which we did ask about causes of warming, and in which we also explained that the survey was designed to have only a few key questions in order to maximize response. Granqvist also questioned our response rate, but as we explained in the report (with references), our response rate is typical for this type of survey. We actually were thrilled to receive more than 3000 responses, given that scientists are generally very busy. We also did not claim “there are no differences between the scientists.” Our data clearly show some differences, especially across subdisciplines, and we concluded there was “largely” no debate among the scientists most qualified to have an informed opinion on the topic.

Cost-effective ways of delivering enquiry services: a rapid review.

PubMed

Sutton, Anthea; Grant, Maria J

2011-12-01

In the recent times of recession and budget cuts, it is more important than ever for library and information services to deliver cost-effective services. This rapid review aims to examine the evidence for the most cost-effective ways of delivering enquiry services. A literature search was conducted on LISA (Library and Information Sciences Abstracts) and MEDLINE. Searches were limited to 2007 onwards. Eight studies met the inclusion criteria. The studies covered hospital and academic libraries in the USA and Canada. Services analysed were 'point-of-care' librarian consultations, staffing models for reference desks and virtual/digital reference services. Transferable lessons, relevant to health library and information services generally, can be drawn from this rapid review. These suggest that 'point-of-care' librarians for primary care practitioners are a cost-effective way of answering questions. Reference desks can be cost-effectively staffed by student employees or general reference staff, although librarian referral must be provided for more complex and subject-specific enquiries. However, it is not possible to draw any conclusions on virtual/digital reference services because of the limited literature available. Further case analysis studies measuring specific services, particularly enquiry services within a health library and information context, are required. © 2011 The authors.

Bruxism and genetics: a review of the literature.

PubMed

Lobbezoo, F; Visscher, C M; Ahlberg, J; Manfredini, D

2014-09-01

People who suffer from bruxism (teeth-grinding) often ask their dentists whether their condition is hereditary. The purpose of this study is to enable dentists to provide an 'evidence-based' answer to this question. The biomedical literature was searched using PubMed, and 32 publications were identified, of which nine proved relevant to the research question. The references cited by the publications identified yielded one further publication, bringing the total number of publications included in the analysis to 10. Four publications related to family studies, five related to twin studies and one related to a DNA analysis. With the exception of one of the twin studies, all the included studies concluded that bruxism appears to be (in part) genetically determined. Dentists whose patients ask them about bruxism can therefore tell them that teeth-grinding does indeed 'run in families'. © 2014 John Wiley & Sons Ltd.

Three questions you need to ask about your brand.

PubMed

Keller, Kevin Lane; Sternthal, Brian; Tybout, Alice

2002-09-01

Traditionally, the people responsible for positioning brands have concentrated on the differences that set each brand apart from the competition. But emphasizing differences isn't enough to sustain a brand against competitors. Managers should also consider the frame of reference within which the brand works and the features the brand shares with other products. Asking three questions about your brand can help: HAVE WE ESTABLISHED A FRAME?: A frame of reference--for Coke, it might be as narrow as other colas or as broad as all thirst-quenching drinks--signals to consumers the goal they can expect to achieve by using a brand. Brand managers need to pay close attention to this issue, in some cases expanding their focus in order to preempt the competition. ARE WE LEVERAGING OUR POINTS OF PARITY?: Certain points of parity must be met if consumers are to perceive your product as a legitimate player within its frame of reference. For instance, consumers might not consider a bank truly a bank unless it offers checking and savings plans. ARE THE POINTS OF DIFFERENCE COMPELLING?: A distinguishing characteristic that consumers find both relevant and believable can become a strong, favorable, unique brand association, capable of distinguishing the brand from others in the same frame of reference. Frames of reference, points of parity, and points of difference are moving targets. Maytag isn't the only dependable brand of appliance, Tide isn't the only detergent with whitening power, and BMWs aren't the only cars on the road with superior handling. The key questions you need to ask about your brand may not change, but their context certainly will. The saviest brand positioners are also the most vigilant.

Science fiction provides a genre in which metaphysical questions concerning the ultimate structure of reality regularly arise. In addressing these questions, contemporary scientists tend to assume that the questions are of a scientific nature and should be handled solely by reference to our best theories. In this paper, it is argued that we cannot afford to neglect the role of conceptual analysis - a distinctively philosophical task - in thinking critically about the possibilities that science fiction claims to describe.

On two kinds of delusion of reference.

PubMed

Startup, Mike; Startup, Sue

2005-11-15

Although delusions of reference are one of the most common psychotic symptoms, they have been the focus of little research. The aims of the present research were, first, to determine whether it is possible to identify different kinds of referential delusions reliably and, if so, to investigate associations among them and between these delusions and other positive psychotic symptoms. Participants with a diagnosis of schizophrenia (n=57) were recruited from a volunteer register (n=26) and from inpatient psychiatric wards (n=31). They were interviewed with the Scale for the Assessment of Positive Symptoms (SAPS) except that the questions about ideas and delusions of reference were replaced with questions targeted at seven particular delusions and three content areas. Ratings were made independently by two assessors. Agreement between the assessors was high for all of the delusions of reference and other psychotic symptoms. A factor analysis of these ratings revealed two factors that represent delusions of communication and delusions of observation. Only delusions of observation were associated with hallucinations and persecutory ideation. Delusions of communication showed few significant correlations with other symptoms and therefore appear to require different explanations.

The qualitative orientation in medical education research.

PubMed

Cleland, Jennifer Anne

2017-06-01

Qualitative research is very important in educational research as it addresses the "how" and "why" research questions and enables deeper understanding of experiences, phenomena and context. Qualitative research allows you to ask questions that cannot be easily put into numbers to understand human experience. Getting at the everyday realities of some social phenomenon and studying important questions as they are really practiced helps extend knowledge and understanding. To do so, you need to understand the philosophical stance of qualitative research and work from this to develop the research question, study design, data collection methods and data analysis. In this article, I provide an overview of the assumptions underlying qualitative research and the role of the researcher in the qualitative process. I then go on to discuss the type of research objectives which are common in qualitative research, then introduce the main qualitative designs, data collection tools, and finally the basics of qualitative analysis. I introduce the criteria by which you can judge the quality of qualitative research. Many classic references are cited in this article, and I urge you to seek out some of these further reading to inform your qualitative research program.

Evaluation of a single-item screening question to detect limited health literacy in peritoneal dialysis patients.

Jain, Deepika; Sheth, Heena; Bender, Filitsa H; Weisbord, Steven D; Green, Jamie A

2014-01-01

Studies have shown that a single-item question might be useful in identifying patients with limited health literacy. However, the utility of the approach has not been studied in patients receiving maintenance peritoneal dialysis (PD). We assessed health literacy in a cohort of 31 PD patients by administering the Rapid Estimate of Adult Literacy in Medicine (REALM) and a single-item health literacy (SHL) screening question "How confident are you filling out medical forms by yourself?" (Extremely, Quite a bit, Somewhat, A little bit, or Not at all). To determine the accuracy of the single-item question for detecting limited health literacy, we performed sensitivity and specificity analyses of the SHL and plotted the area under the receiver operating characteristic (AUROC) curve using the REALM as a reference standard. Using a cut-off of "Somewhat" or less confident, the sensitivity of the SHL for detecting limited health literacy was 80%, and the specificity was 88%. The positive likelihood ratio was 6.9. The SHL had an AUROC of 0.79 (95% confidence interval: 0.52 to 1.00). Our results show that the SHL could be effective in detecting limited health literacy in PD patients.

It is well recognized that interpretations of Mars must begin with the Earth as a reference. The most successful comparisons have focused on understanding geologic processes on the Earth well enough to extrapolate to Mars' environment. Several facets of terrestrial analog studies have been pursued and are continuing. These studies include field workshops, characterization of terrestrial analog sites for Mars, instrument tests, laboratory measurements (including analysis of martian meteorites), and computer and laboratory modeling. The combination of all these activities allows scientists to constrain the processes operating in specific terrestrial environments and extrapolate how similar processes could affect Mars. The Terrestrial Analogs for Mars Community Panel is considering the following two key questions: (1) How do terrestrial analog studies tie in to the MEPAG science questions about life, past climate, and geologic evolution of Mars, and (2) How can future instrumentation be used to address these questions. The panel is considering the issues of data collection, value of field workshops, data archiving, laboratory measurements and modeling, human exploration issues, association with other areas of solar system exploration, and education and public outreach activities.

Objective Many mobile phone resources have been developed to increase access to health education in the developing world, yet few studies have compared these resources or quantified their performance in a resource-limited setting. This study aims to compare the performance of resident physicians in answering clinical scenarios using PubMed abstracts accessed via the PubMed for Handhelds (PubMed4Hh) website versus medical/drug reference applications (Medical Apps) accessed via software on the mobile phone. Methods A two-arm comparative study with crossover design was conducted. Subjects, who were resident physicians at the University of Botswana, completed eight scenarios, each with multi-part questions. The primary outcome was a grade for each question. The primary independent variable was the intervention arm and other independent variables included residency and question. Results Within each question type there were significant differences in ‘percentage correct’ between Medical Apps and PubMed4Hh for three of the six types of questions: drug-related, diagnosis/definitions, and treatment/management. Within each of these question types, Medical Apps had a higher percentage of fully correct responses than PubMed4Hh (63% vs 13%, 33% vs 12%, and 41% vs 13%, respectively). PubMed4Hh performed better for epidemiologic questions. Conclusions While mobile access to primary literature remains important and serves an information niche, mobile applications with condensed content may be more appropriate for point-of-care information needs. Further research is required to examine the specific information needs of clinicians in resource-limited settings and to evaluate the appropriateness of current resources in bridging location- and context-specific information gaps.

Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the 2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required. We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international stakeholders constituting a large reference group, and consolidated into a final list of research questions by a technical working group. Questions on this list were then scored by the reference working group according to five independent and equally weighted criteria. Normalized research priority scores (NRPS) were calculated, and research priority questions were ranked accordingly. A list of 190 priority research questions for improving maternal and perinatal health was scored by 140 stakeholders. Most priority research questions (89%) were concerned with the evaluation of implementation and delivery of existing interventions, with research subthemes frequently concerned with training and/or awareness interventions (11%), and access to interventions and/or services (14%). Twenty-one questions (11%) involved the discovery of new interventions or technologies. Key research priorities in maternal and perinatal health were identified. The resulting ranked list of research questions provides a valuable resource for health research investors, researchers and other stakeholders. We are hopeful that this exercise will inform the post-2015 Development Agenda and assist donors, research-policy decision makers and researchers to invest in research that will ultimately make the most significant difference in the lives of mothers and babies.

Is There a New Service Proletariat? Post-industrial Employment Growth and Social Inequality in Spain

PubMed Central

Garrido, Luis

2008-01-01

In Spain the absolute number of employed persons has increased from about 12,300,000 persons in 1994 to 19,300,000 at the end of 2005. In the same period, the number of immigrants has increased from about 500,000 to more than 4 million. The aim of this paper is to analyse the implications of these changes for social inequality. In particular, we investigate whether a new type of unskilled service class is likely to emerge as a distinct social class. We address this issue by means of three more specific research questions. The first one refers to the pattern of changes in the employment structure by occupational class: has the mentioned employment growth implied an expansion of the swelling service proletariat? The other two questions refer to the issue of demographic class formation: which is the composition of the class structure by gender and country of origin? And, are unskilled service occupations stop-gaps springboards towards better positions, or are they long-term traps? We answer these questions by means of a dynamic analysis of the panel data of the Spanish Labour Force Surveys (SLFS). We study trends over time in the class structure and, then, analyse upward mobility chances and the risk of falling into unemployment from unskilled occupations from year t to year t + 1.

Background Participants in early-phase clinical trials have reported high expectations of benefit from their participation. There is concern that participants misunderstand the trials to which they have consented. Such concern is based on assumptions about what patients mean when they respond to questions about likelihood of benefit. Methods Participants were 27 women and 18 men in early-phase oncology trials at 2 academic medical centers in the United States. To determine whether expectations of benefit differ depending on how patients are queried, we randomly assigned participants to 1 of 3 interviews corresponding to 3 questions about likelihood of benefit: frequency-type, belief-type, and vague. In semistructured interviews, we queried participants about how they understood and answered the question. Participants then answered and discussed one of the other questions. Results Expectations of benefit in response to the belief-type question were significantly greater than expectations in response to the frequency-type and vague questions (P = .02). The most common justifications involved positive attitude (n = 27 [60%]) and references to physical health (n = 23 [51%]). References to positive attitude were most common among participants with higher (> 70%) expectations (n = 11 [85%]) and least common among those with lower (< 50%) expectations (n = 3 [27%]). Conclusions The wording of questions about likelihood of benefit shapes the expectations that patients express. Also, patients who express high expectations may not do so to communicate understanding, but rather to register optimism. Ongoing research will clarify the meaning of high expectations and examine methods for assessing understanding in this context. PMID:18378940

The current study sought to evaluate the suicide prevention gatekeeper training program QPR (Question, Persuade, and Refer) among school personnel using a non-equivalent control group design. Substantial gains were demonstrated from pre- to post-test for attitudes, knowledge, and beliefs regarding suicide and suicide prevention. Exploratory analyses revealed the possible moderating effects of age, professional role, prior training, and recent contact with suicidal youth on QPR participants' general knowledge, questioning, attitudes toward suicide and suicide prevention, QPR quiz scores, and self-efficacy. The need for replication using a more rigorous experimental design in the context of strong community collaboration is discussed.

Critical Speed of The Glass Glue Machine's Creep and Influence Factors Analysis

Yang, Jianxi; Huang, Jian; Wang, Liying; Shi, Jintai

When automatic glass glue machine works, two questions of the machine starting vibrating and stick-slip motion are existing. These problems should be solved. According to these questions, a glue machine's model for studying stick-slip is established. Based on the dynamics system describing of the model, mathematical expression is presented. The creep critical speed expression is constructed referring to existing research achievement and a new conclusion is found. The influencing factors of stiffness, dampness, mass, velocity, difference of static and kinetic coefficient of friction are analyzed through Matlab simulation. Research shows that reasonable choice of influence parameters can improve the creep phenomenon. These all supply the theory evidence for improving the machine's motion stability.

Purpose The aim of this study was to evaluate the added utility of embedding images for findings described in radiology text reports to referring clinicians. Methods Thirty-five cases referred for abdominal CT scans in 2007 and 2008 were included. Referring physicians were asked to view text-only reports, followed by the same reports with pertinent images embedded. For each pair of reports, a questionnaire was administered. A 5-point, Likert-type scale was used to assess if the clinical query was satisfactorily answered by the text-only report. A “yes-or-no” question was used to assess whether the report with images answered the clinical query better; a positive answer to this question generated “yes-or-no” queries to examine whether the report with images helped in making a more confident decision on management, whether it reduced time spent in forming the plan, and whether it altered management. The questionnaire asked whether a radiologist would be contacted with queries on reading the text-only report and the report with images. Results In 32 of 35 cases, the text-only reports satisfactorily answered the clinical queries. In these 32 cases, the reports with attached images helped in making more confident management decisions and reduced time in planning management. Attached images altered management in 2 cases. Radiologists would have been consulted for clarifications in 21 and 10 cases on reading the text-only reports and the reports with embedded images, respectively. Conclusions Providing relevant images with reports saves time, increases physicians' confidence in deciding treatment plans, and can alter management. PMID:20193926

Background and Objective: The present study was conducted to design and measure psychometrics of mothers’ lifestyle scale during pregnancy with regards to Iranians’ cultural norms and an approach to social determinants. Method: this study, started by reviewing previous studies and exploring similar questionnaires that examine different domains of lifestyle (nutrition, exercising, self-care, smoking, using alcohol and illegal drugs, social relations, and stress control), then besides translating questions of the questionnaires, content of some questions was modified and proper statements with regards to social determinant of health and Iranian cultural, was used. Secondly, the validity of the designed instruments was determined using face, content, criterion, and construct validity. Thirdly, the reliability of the measurement instruments was examined using Cronbach’s alpha. Participants were Healthy Iranian pregnant women (37-42 week) who refer to selected hospital for delivery. Results: In the first step of the study, of the 222 questions obtained from a review of the related instruments, certain questions were omitted due to their irrelevance to social determinants of health and finally 160 questions were selected in 10 sections. After determining the face and content validity qualitatively and quantitatively and exploratory factor analysis, the number of questionnaire items was reduced to 132. Calculation of Cronbach’s alpha confirmed the high internal consistency (0.76) of the questionnaire. Conclusion: This measurement instrument was designed in the context of the Iranian culture and sounded suitable for studying the pregnant women’s lifestyle due to its appropriate validity and reliability, simplicity, and functionality in different situations.

Are Cantonese-speakers really descriptivists? Revisiting cross-cultural semantics.

Lam, Barry

2010-05-01

In an article in Cognition [Machery, E., Mallon, R., Nichols, S., & Stich, S. (2004). Semantics cross-cultural style. Cognition, 92, B1-B12] present data which purports to show that East Asian Cantonese-speakers tend to have descriptivist intuitions about the referents of proper names, while Western English-speakers tend to have causal-historical intuitions about proper names. Machery et al. take this finding to support the view that some intuitions, the universality of which they claim is central to philosophical theories, vary according to cultural background. Machery et al. conclude from their findings that the philosophical methodology of consulting intuitions about hypothetical cases is flawed vis a vis the goal of determining truths about some philosophical domains like philosophical semantics. In the following study, three new vignettes in English were given to Western native English-speakers, and Cantonese translations were given to native Cantonese-speaking immigrants from a Cantonese community in Southern California. For all three vignettes, questions were given to elicit intuitions about the referent of a proper name and the truth-value of an uttered sentence containing a proper name. The results from this study reveal that East Asian Cantonese-speakers do not differ from Western English-speakers in ways that support Machery et al.'s conclusions. This new data concerning the intuitions of Cantonese-speakers raises questions about whether cross-cultural variation in answers to questions on certain vignettes reveal genuine differences in intuitions, or whether such differences stem from non-intuitional differences, such as differences in linguistic competence.

Which Individuals To Choose To Update the Reference Population? Minimizing the Loss of Genetic Diversity in Animal Genomic Selection Programs.

PubMed

Eynard, Sonia E; Croiseau, Pascal; Laloë, Denis; Fritz, Sebastien; Calus, Mario P L; Restoux, Gwendal

Genomic selection (GS) is commonly used in livestock and increasingly in plant breeding. Relying on phenotypes and genotypes of a reference population, GS allows performance prediction for young individuals having only genotypes. This is expected to achieve fast high genetic gain but with a potential loss of genetic diversity. Existing methods to conserve genetic diversity depend mostly on the choice of the breeding individuals. In this study, we propose a modification of the reference population composition to mitigate diversity loss. Since the high cost of phenotyping is the limiting factor for GS, our findings are of major economic interest. This study aims to answer the following questions: how would decisions on the reference population affect the breeding population, and how to best select individuals to update the reference population and balance maximizing genetic gain and minimizing loss of genetic diversity? We investigated three updating strategies for the reference population: random, truncation, and optimal contribution (OC) strategies. OC maximizes genetic merit for a fixed loss of genetic diversity. A French Montbéliarde dairy cattle population with 50K SNP chip genotypes and simulations over 10 generations were used to compare these different strategies using milk production as the trait of interest. Candidates were selected to update the reference population. Prediction bias and both genetic merit and diversity were measured. Changes in the reference population composition slightly affected the breeding population. Optimal contribution strategy appeared to be an acceptable compromise to maintain both genetic gain and diversity in the reference and the breeding populations. Copyright © 2018 Eynard et al.

In the Huang di nei jing ( Huangdi ' s Internal Classic ), jin ye (fluid and humor) is described in two senses, broad and narrow, though not so strictly.Sometimes, jin ye is explained ambiguously as "sweat" and "urine" , as in the phrase "the bladder, being a house of jin ye " , here " jin ye " refers to the urine. In the Qi jue lun pian of Su wen ( Chapter on Qi - Syncope of Plain Questions ) , the " bao " in the sentence "heat of bao moved to bladder" refersto the uterus. In the Shi cong rong lun pian ( Chapter of Readily Inspecting ) of Plain Questions , the "bladder" in the phrase "gallbladder, stomach, large intestine, small intestine, spleen, bao and bladder" , which, being an annotation of " bao " originally, is mistakenly incorporated into the text of the Classic . In the Wu wei lun of Ling shu ( On Five Tastes in Miraculous Pivot ) , the " bao " in " bao of bladder" refers to the external hou (external manifestation) of the bladder, that is the scrotum. In the Bei ji qian jin yao fang ( Essential Prescriptions Worth a Thousand Gold for Emergencies ) , the short sentence " pang guang zou bao " is an error in itself. In the sentence of "settled in the bao and zhi causing to dream of defecation and urination" in the Yin xie fa meng (Dreams due to Evils) of Miraculous Pivot , " bao " refers to uterus, and " zhi " to anus. In Bi lun pian ( Chapter on Impediment ) of Plain Questions , "the man suffered bao bimight feel internal pain when the lesser abdomen and bladder are pressed" , here, " bao " refers to the bladder. In the Wu yin wu wei ( Chapter on Five Sound and Five Tastes ) of Miraculous Pivot , the " bao " in the sentence "thoroughfare vessel and conception vessel all starts from bao " , again, " bao " here refers to the bladder, rather than to the uterus. From the above descriptions of "bladder" and " bao " in the Huangdi ' s Internal Classic , the "bladder" in ancient medical books refers to the substantial bladder, an anatomical organ, and " bao " refers to cystiform organs, including the bladder, uterus, scrotum etc.

The key questions addressed to meet this objective include: (1) Are there any differences in the level of bird activity, called ''utilization rate'' or ''use'', with the operating wind plant and within the surrounding undeveloped areas (reference area)?; (2) Are there any differences in the rate of bird fatalities (or avian fatality) within the operatingmore » wind plant or the surrounding undeveloped areas (reference area)?; (3) Does bird use, fatality rates, or bird risk index vary according to the geographic location, type and size of wind turbine, and/or type of bird within the operating wind plant and surrounding undeveloped areas (reference area)?; and (4) How do raptor fatality rates at San Gorgonio compare to other wind projects with comparable data?« less

U.S. residential consumer product information: Validation of methods for post-stratification weighting of Amazon Mechanical Turk surveys

DOE Office of Scientific and Technical Information (OSTI.GOV)

Greenblatt, Jeffery B.; Yang, Hung-Chia; Desroches, Louis-Benoit

2013-04-01

We present two post-stratification weighting methods to validate survey data collected using Amazon Mechanical Turk (AMT). Two surveys focused on appliance and consumer electronics devices were administered in the spring and summer of 2012 to each of approximately 3,000 U.S. households. Specifically, the surveys asked questions about residential refrigeration products, televisions (TVs) and set-top boxes (STBs). Filtered data were assigned weights using each of two weighting methods, termed “sequential” and “simultaneous,” by examining up to eight demographic variables (income, education, gender, race, Hispanic origin, number of occupants, ages of occupants, and geographic region) in comparison to reference U.S. demographic datamore » from the 2009 Residential Energy Consumption Survey (RECS). Five key questions from the surveys (number of refrigerators, number of freezers, number of TVs, number of STBs and primary service provider) were evaluated with a set of statistical tests to determine whether either method improved the agreement of AMT with reference data, and if so, which method was better. The statistical tests used were: differences in proportions, distributions of proportions (using Pearson’s chi-squared test), and differences in average numbers of devices as functions of all demographic variables. The results indicated that both methods generally improved the agreement between AMT and reference data, sometimes greatly, but that the simultaneous method was usually superior to the sequential method. Some differences in sample populations were found between the AMT and reference data. Differences in the proportion of STBs reflected large changes in the STB market since the time our reference data was acquired in 2009. Differences in the proportions of some primary service providers suggested real sample bias, with the possible explanation that AMT user are more likely to subscribe to providers who also provide home internet service. Differences in other variables, while statistically significant in some cases, were nonetheless considered to be minor. Depending on the intended purpose of the data collected using AMT, these biases may or may not be important; to correct them, additional questions and/or further post-survey adjustments could be employed. In general, based on the analysis methods and the sample datasets used in this study, AMT surveys appeared to provide useful data on appliance and consumer electronics devices.« less

Butler, Andrew C.; Dennis, Nancy A.; Marsh, Elizabeth J.

2012-01-01

People can acquire both true and false knowledge about the world from fictional stories (Marsh & Fazio, 2007). The present study explored whether the benefits and costs of learning about the world from fictional stories extend beyond memory for directly stated pieces of information. Of interest was whether readers would use correct and incorrect story references to make deductive inferences about related information in the story, and then integrate those inferences into their knowledge bases. Subjects read stories containing correct, neutral, and misleading references to facts about the world; each reference could be combined with another reference that occurred in a later sentence to make a deductive inference. Later, they answered general knowledge questions that tested for these deductive inferences. The results showed that subjects generated and retained the deductive inferences regardless of whether the inferences were consistent or inconsistent with world knowledge, and irrespective of whether the references were placed consecutively in the text or separated by many sentences. Readers learn more than what is directly stated in stories; they use references to the real world to make both correct and incorrect inferences that are integrated into their knowledge bases.

From art to science: a new epistemological status for medicine? On expectations regarding personalized medicine.

PubMed

Wiesing, Urban

2017-12-20

Personalized medicine plays an important role in the development of current medicine. Among the numerous statements regarding the future of personalized medicine, some can be found that accord medicine a new scientific status. Medicine will be transformed from an art to a science due to personalized medicine. This prognosis is supported by references to models of historical developments. The article examines what is meant by this prognosis, what consequences it entails, and how feasible it is. It refers to the long tradition of epistemological thinking in medicine and the use of historical models for the development of medicine. The possible answers to the question "art or science" are systematized with respect to the core question about the relationship between knowledge and action. The prediction for medicine to develop from an 'empirical healing art' to a 'rational, molecular science' is nonsensical from an epistemological point of view. The historical models employed to substantiate the development of personalized medicine are questionable.

2006-01-01

BACKGROUND Patients with limited literacy skills are routinely encountered in clinical practice, but they are not always identified by clinicians. OBJECTIVE To evaluate 3 candidate questions to determine their accuracy in identifying patients with limited or marginal health literacy skills. METHODS We studied 305 English-speaking adults attending a university-based primary care clinic. Demographic items, health literacy screening questions, and the Rapid Estimate of Adult Literacy in Medicine (REALM) were administered to patients. To determine the accuracy of the candidate questions for identifying limited or marginal health literacy skills, we plotted area under the receiver operating characteristic (AUROC) curves for each item, using REALM scores as a reference standard. RESULTS The mean age of subjects was 49.5; 67.5% were female, 85.2% Caucasian, and 81.3% insured by TennCare and/or Medicare. Fifty-four (17.7%) had limited and 52 (17.0%) had marginal health literacy skills. One screening question, “How confident are you filling out medical forms by yourself?” was accurate in detecting limited (AUROC of 0.82; 95% confidence interval [CI]=0.77 to 0.86) and limited/marginal (AUROC of 0.79; 95% CI=0.74 to 0.83) health literacy skills. This question had significantly greater AUROC than either of the other questions (P<.01) and also a greater AUROC than questions based on demographic characteristics. CONCLUSIONS One screening question may be sufficient for detecting limited and marginal health literacy skills in clinic populations. PMID:16881950

Reference in human and non-human primate communication: What does it take to refer?

PubMed

Sievers, Christine; Gruber, Thibaud

2016-07-01

The concept of functional reference has been used to isolate potentially referential vocal signals in animal communication. However, its relatedness to the phenomenon of reference in human language has recently been brought into question. While some researchers have suggested abandoning the concept of functional reference altogether, others advocate a revision of its definition to include contextual cues that play a role in signal production and perception. Empirical and theoretical work on functional reference has also put much emphasis on how the receiver understands the referential signal. However, reference, as defined in the linguistic literature, is an action of the producer, and therefore, any definition describing reference in non-human animals must also focus on the producer. To successfully determine whether a signal is used to refer, we suggest an approach from the field of pragmatics, taking a closer look at specific situations of signal production, specifically at the factors that influence the production of a signal by an individual. We define the concept of signaller's reference to identify intentional acts of reference produced by a signaller independently of the communicative modality, and illustrate it with a case study of the hoo vocalizations produced by wild chimpanzees during travel. This novel framework introduces an intentional approach to referentiality. It may therefore permit a closer comparison of human and non-human animal referential behaviour and underlying cognitive processes, allowing us to identify what may have emerged solely in the human lineage.

2004-01-01

The Astrophysics of Reference Frame Tie Objects Key Science program will investigate the underlying physics of SIM grid objects. Extragalactic objects in the SIM grid will be used to tie the SIM reference frame to the quasi-inertial reference frame defined by extragalactic objects and to remove any residual frame rotation with respect to the extragalactic frame. The current realization of the extragalactic frame is the International Celestial Reference Frame (ICRF). The ICRF is defined by the radio positions of 212 extragalactic objects and is the IAU sanctioned fundamental astronomical reference frame. This key project will advance our knowledge of the physics of the objects which will make up the SIM grid, such as quasars and chromospherically active stars, and relates directly to the stability of the SIM reference frame. The following questions concerning the physics of reference frame tie objects will be investigated.

Redefining reference in an academic health sciences library: planning for change.

Gray, S A; Brower, S; Munger, H; Start, A; White, P

2001-01-01

Deciding that changes in the pattern of questions at the reference desk required focused consideration, the reference librarians at the Health Sciences Library of the University at Buffalo held a planning retreat. Technology-induced changes in the information-seeking behavior and reference needs of the library's clientele caused a reassessment of how these needs could best be met and what is the best use of librarians' time. The librarians considered current trends in reference in other academic libraries, the specific needs of the clientele of the Health Sciences Library, and the strengths and expertise of the library staff. The results of this structured discussion produced ideas for redefining reference to provide customized services for the clients and environment.

Children of home dialysis patients.

PubMed

Tsaltas, M O

1976-12-13

Fifteen children of six families in which one parent was undergoing home dialysis were examined by the Minnesota Multiphasic Personality Inventory, human figure drawings, and family interviews. All the children were found to be clinically depressed, and two thirds had a history of being referred by teachers to school counselors and psychiatrists for behavioral problems in school. Of these referred children, all showed disorders of psychomotor activity and reduced academic achievement. There was no clear-cut evidence that these children were depressed because of exposure to home dialysis per se. The most disturbed children seemed to be responding to depressed parents or to partial object loss. A controlled, prospective study is planned to clarify this question.

Understanding essential tremor: progress on the biological front.

PubMed

Louis, Elan D

2014-06-01

For many years, little was written about the underlying biology of ET, despite its high prevalence. Discussions of disease mechanisms were dominated by a focus on tremor physiology. The traditional model of ET, the olivary model, was proposed in the 1970s. The model suffers from several critical problems, and its relevance to ET has been questioned. Recent mechanistic research has focused on the cerebellum. Clinical and neuroimaging studies strongly implicate the importance of this brain region in ET. Recent mechanistic research has been grounded more in tissue-based changes (i.e., postmortem studies of the brain). These studies have collectively and systematically identified a sizable number of changes in the ET cerebellum, and have led to a new model of ET, referred to as the cerebellar degenerative model. Hence, there is a renewed interest in the science behind the biology of ET. How the new understanding of ET will translate into treatment changes is an open question.

2012-12-01

Progress has been made in the diagnosis and treatment of urolithiasis over the last 10 years, after the first version of the Guidelines on Urolithiasis was published in December 2002. Considering such a situation, the revised version is due for publication soon. At this symposium, 3 persons who were engaged in the revision of the guidelines presented its digest. The revised version is characterized by the adoption of a "Frequently asked questions style", aiming to facilitate its usage as a reference book or dictionary readers can refer to when a question is raised in practice. It may be possible to further promote the medical treatment of urolithiasis by effectively using this in combination with the relatively textbook-like first version.

The politician's point of view

The politician's point of view refers to studies which prove that neither a socio-economic development plan which ignores population questions, nor population education in isolation, can succeed. Educated people tend to have fewer children and to provide better education for them, while girls marrying before the age of 20 have little hope of continuing education and are subject to other social pressures. Examples are given from population education programs in Egypt.

The School Physical Activity and Nutrition (SPAN) questionnaire was developed as a surveillance instrument to measure physical activity, nutrition attitudes, and dietary and physical activity behaviors in children and adolescents. The SPAN questionnaire has 2 versions. This study was conducted to evaluate the validity of food consumption items from the elementary school version of the SPAN questionnaire. Validity was assessed by comparing food items selected on the questionnaire with food items reported from a single 24-hour recall covering the same reference period. 5 elementary schools in Indiana. Fourth-grade student volunteers (N = 121) from 5 elementary schools. Agreement between responses to SPAN questionnaire items and reference values obtained through 24-hour dietary recall. The agreement between the questionnaire and the 24-hour recall was measured using Spearman correlation, percentage agreement, and kappa statistic. Correlation between SPAN item responses and recall data ranged from .25 (bread and related products) to .67 (gravy). The percentage agreement ranged from 26% (bread and related products) to 90% (gravy). The kappa statistic varied from .06 (chocolate candy) to .60 (beans). Results from this study indicate that the SPAN questionnaire can be administered in the classroom quickly and easily to measure many previous day dietary behaviors of fourth graders. However, questions addressing consumption of "vegetables," "candy," and "snacks" need further investigation.

Interventional clinical studies conducted in the regulated drug research environment are reported using International Council for Harmonisation (ICH) regulatory guidance documents: ICH E3 on the structure and content of clinical study reports (CSRs) published in 1995 and ICH E3 supplementary Questions & Answers (Q & A) published in 2012.Since the ICH guidance documents were published, there has been heightened awareness of the importance of disclosure of clinical study results. The use of the CSR as a key source document to fulfil emerging obligations has resulted in a re-examination of how ICH guidelines are applied in CSR preparation. The dynamic regulatory and modern drug development environments create emerging reporting challenges. Regulatory medical writing and statistical professionals developed Clarity and Openness in Reporting: E3-based (CORE) Reference over a 2-year period. Stakeholders contributing expertise included a global industry association, regulatory agency, patient advocate, academic and Principal Investigator representatives. CORE Reference should help authors navigate relevant guidelines as they create CSR content relevant for today's studies. It offers practical suggestions for developing CSRs that will require minimum redaction and modification prior to public disclosure.CORE Reference comprises a Preface, followed by the actual resource. The Preface clarifies intended use and underlying principles that inform resource utility. The Preface lists references contributing to development of the resource, which broadly fall into 'regulatory' and 'public disclosure' categories. The resource includes ICH E3 guidance text, ICH E3 Q & A 2012-derived guidance text and CORE Reference text, distinguished from one another through the use of shading. Rationale comments are used throughout for clarification purposes.A separate mapping tool comparing ICH E3 sectional structure and CORE Reference sectional structure is also provided.Together, CORE Reference and the mapping tool constitute the user manual. This publication is intended to enhance the use, understanding and dissemination of CORE Reference.The CORE Reference user manual and the associated website (http://www.core-reference.org) should improve the reporting of interventional clinical studies.Periodic updates of CORE Reference are planned to maintain its relevance. CORE Reference was registered with http://www.equator-network.org on 23 March 2015.

What constitutes an efficient reference frame for vision?

Tadin, Duje; Lappin, Joseph S.; Blake, Randolph; Grossman, Emily D.

2015-01-01

Vision requires a reference frame. To what extent does this reference frame depend on the structure of the visual input, rather than just on retinal landmarks? This question is particularly relevant to the perception of dynamic scenes, when keeping track of external motion relative to the retina is difficult. We tested human subjects’ ability to discriminate the motion and temporal coherence of changing elements that were embedded in global patterns and whose perceptual organization was manipulated in a way that caused only minor changes to the retinal image. Coherence discriminations were always better when local elements were perceived to be organized as a global moving form than when they were perceived to be unorganized, individually moving entities. Our results indicate that perceived form influences the neural representation of its component features, and from this, we propose a new method for studying perceptual organization. PMID:12219092

To compare the quality of referrals of patients with complex medical problems from nurse practitioners (NPs), physician assistants (PAs), and physicians to general internists. We conducted a retrospective comparison study involving regional referrals to an academic medical center from January 1, 2009, through December 31, 2010. All 160 patients referred by NPs and PAs combined and a random sample of 160 patients referred by physicians were studied. Five experienced physicians blinded to the source of referral used a 7-item instrument to assess the quality of referrals. Internal consistency, interrater reliability, and dimensionality of item scores were determined. Differences between item scores for patients referred by physicians and those for patients referred by NPs and PAs combined were analyzed by using multivariate ordinal logistical regression adjusted for patient age, sex, distance of the referral source from Mayo Clinic, and Charlson Index. Factor analysis revealed a 1-dimensional measure of the quality of patient referrals. Interrater reliability (intraclass correlation coefficient for individual items: range, 0.77-0.93; overall, 0.92) and internal consistency for items combined (Cronbach α=0.75) were excellent. Referrals from physicians were scored higher (percentage of agree/strongly agree responses) than were referrals from NPs and PAs for each of the following items: referral question clearly articulated (86.3% vs 76.0%; P=.0007), clinical information provided (72.6% vs 54.1%; P=.003), documented understanding of the patient's pathophysiology (51.0% vs 30.3%; P<.0001), appropriate evaluation performed locally (60.3% vs 39.0%; P<.0001), appropriate management performed locally (53.5% vs 24.1%; P<.0001), and confidence returning patient to referring health care professional (67.8% vs 41.4%; P<.0001). Referrals from physicians were also less likely to be evaluated as having been unnecessary (30.1% vs 56.2%; P<.0001). The quality of referrals to an academic medical center was higher for physicians than for NPs and PAs regarding the clarity of the referral question, understanding of pathophysiology, and adequate prereferral evaluation and documentation.

How should we question young children's understanding of aspectuality?

PubMed

Waters, Gillian M; Beck, Sarah R

2012-09-01

In two experiments, we investigated whether 4- to 5-year-old children's ability to demonstrate their understanding of aspectuality was influenced by how the test question was phrased. In Experiment 1, 60 children chose whether to look or feel to gain information about a hidden object (identifiable by sight or touch). Test questions referred either to the perceptual aspect of the hidden object (e.g., whether it was red or blue), the modality dimension (e.g., what colour it was), or the object's identity (e.g., which one it was). Children who heard the identity question performed worse than those who heard the aspect or dimension question. Further investigation in Experiment 2 (N= 23) established that children's difficulty with the identity question was not due to a problem recalling the objects. We discuss how the results of these methodological investigations impact on researchers' assessment of the development of aspectuality understanding. ©2011 The British Psychological Society.

We describe the construction of MYCIN II, a prototype system that provides for content-based markup and search of a forthcoming clinical therapeutics textbook, Antimicrobial Therapy and Vaccines. Existing commercial search technology for digital references utilizes generic tools such as textword-based searches with geographical or statistical refinements. We suggest that the drawbacks of such systems significantly restrict their use in everyday clinical practice. This is in spite of the fact that there is a great need for the information contained within these same references. The system we describe is intended to supplement keyword searching so that certain important questions can be asked easily and can be answered reliably (in terms of precision and recall). Our method attacks this problem in a restricted domain of knowledge-clinical infectious disease. For example, we would like to be able to answer the class of questions exemplified by the following query: "What antimicrobial agents can be used to treat endocarditis caused by Eikenella corrodens?" We have compiled and analyzed a list of such questions to develop a concept-based markup scheme. This scheme was then applied within an HTML markup to electronically "highlight" passages from three textbook chapters. We constructed a functioning web-based search interface. Our system also provides semi-automated querying of PubMed using our concept markup and the user's actions as a guide. PMID:9929205

2006-01-01

The research aim is to study the working attitude of a physician towards his patient with obstetric failures in the emotional component aspect. A sample of 164 gynecological doctors was encompassed by the study. The physicians were mainly interviewed during various types of training courses, specialist conventions and during personal meetings. A 44-question anonymous questionnaire was directed at gynecologists. The question was closed. The survey used for the research (in "ex post facto" procedure) matches quantity and quality elements. Concerning the emotional aspect referred to the most difficult in the physician-- patient relation: 18% of the respondents stated they had positive feelings towards the patient, 16% had self-centred feelings and 1% had negative feelings towards the patient. Concerned the feelings of the doctor when the patient and her husband are in a situation of obstetric failure: 49% shared positive feelings in experiencing obstetric failure in patients, 38% concentrated on themselves and their own feelings and 4% gave a decided negative reply. Physicians' attitudes were measured in relation to the death of a patient: 52% related that experience very personally to themselves, 4% of the physicians referred to the death of their patient with a sense of great sorrow and 1% were negatively trying to put the blame on the deceased patient. The most emotionally difficult obstetric failure in the doctor--patient relation was the death of a prenatal child; the most effective reaction to the sorrow of a mother after the loss of her child was support and bringing relief to the patient; 38% of gynecologists have not answered the question because of luck of such experience and because of the too difficult trauma experience.

Previous work suggests that the estimated age in adults' earliest autobiographical memories depends on age information implied by the experimental context [e.g., Kingo, O. S., Bohn, A., & Krøjgaard, P. (2013). Warm-up questions on early childhood memories affect the reported age of earliest memories in late adolescence. Memory, 21(2), 280-284. doi: 10.1080/09658211.2012.729598 ] and that the age in decontextualised snippets of memory is younger than in more complete accounts (i.e., event memories [Bruce, D., Wilcox-O'Hearn, L. A., Robinson, J. A., Phillips-Grant, K., Francis, L., & Smith, M. C. (2005). Fragment memories mark the end of childhood amnesia. Memory & Cognition, 33(4), 567-576. doi: 10.3758/BF03195324 ]). We examined the malleability of the estimated age in undergraduates' earliest memories and its relation with memory quality. In Study 1 (n = 141), vignettes referring to events happening at age 2 rendered earlier reported ages than examples referring to age 6. Exploratory analyses suggested that event memories were more sensitive to the age manipulation than memories representing a single, isolated scene (i.e., snapshots). In Study 2 (n = 162), asking self-relevant and public-event knowledge questions about participants' preschool years prior to retrieval yielded comparable average estimated ages. Both types of semantic knowledge questions rendered earlier memories than a no-age control task. Overall, the reported age in snapshots was younger than in event memories. However, age-differences between memory types across conditions were not statistically significant. Together, the results add to the growing literature indicating that the average age in earliest memories is not as fixed as previously thought.

Whose Music? Music Education and Cultural Issues: Debates about What Music to Study Can Raise Questions Related to the Very Purpose of Music Education

ERIC Educational Resources Information Center

Rideout, Roger

Any music teacher who has planned a holiday concert knows about the politics underlying the selection of appropriate music. Some students do not sing carols or cite lyrics that refer to fictional characters such as elves, goblins, or Harry Potter. Still others do not sing the national anthem. To these students or their parents, such songs…

'Where were your clothes?' Eliciting descriptions of clothing placement from children alleging sexual abuse in criminal trials and forensic interviews.

PubMed

Stolzenberg, Stacia N; Lyon, Thomas D

2017-09-01

The present study examined how children alleging sexual abuse are asked about clothing placement during abusive episodes, both in criminal trials and forensic interviews. The placement of clothing is of great importance, because it facilitates distinguishing abusive touch from non-abusive touch, as well as the severity of abuse when the touching is in fact sexual. If clothing has not been removed, then sexual abuse appears less likely and certain types of sexual contact are physically impossible (or at least highly improbable). We examined how trial attorneys ( n = 142) and forensic interviewers in investigative interviews ( n = 155) questioned 5- 12-year-olds about the location of clothing during alleged sexual abuse. To do so, we identified all question-answer pairs that included references to clothing placement, and coded for the clothing item mentioned, whether the interviewer elicited information about clothing placement or the child spontaneously provided such information, question-type, and response-type. Discussions about clothing placement were commonplace in both settings, particularly in court. Fewer than one in five question-answer pairs about clothing placement were spontaneous mentions by children; the questioner elicited most discussions. When interviewers asked wh- questions rather than yes/no and forced-choice questions, children provided more elaboration, more detailed clothing information, and were over six times more likely to describe clothing placement in a fashion that could not be captured by a single preposition (e.g., neither on nor off). The findings suggest that descriptions of clothing placement are subject to serious misinterpretation when closed-ended questions are asked.

Harmful drinking is common in medical inpatients, yet commonly missed due in part to time pressures. A screening question about past year heavy drinking recommended by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) has been validated in primary care and emergency room settings. We tested the psychometric properties of a modified single screening question (SSQ) in hospitalized patients referred to a consultation-liaison service. A psychiatry attending (n = 40), a psychiatry resident (n = 30) and a medical student (n = 30) administered the SSQ, followed by a self-report 10-item Alcohol Use Disorders Identification Test (AUDIT) to a sample of 100 consultation-liaison patients who were able to give informed consent for participation. Using the AUDIT as a reference, the sensitivity and specificity of the SSQ to detect harmful drinking in this sample were .96 and .82, respectively. Gender differences in specificity were not found. The single question also had a strong correlation with dependence (r(b) = .457, p < .001), and harmful use (r(b) = .620, p < .001) subscales of the AUDIT. The SSQ about past year heavy drinking can rapidly identify harmful drinking in alert nonpsychotic consultation-liaison patients. Copyright © 2011 The Academy of Psychosomatic Medicine.

Visualizing Culturally Relevant Science Pedagogy Through Photonarratives of Black Middle School Teachers

NASA Astrophysics Data System (ADS)

Goldston, M. Jenice; Nichols, Sharon

2009-04-01

This study situated in a Southern resegregated Black middle school involved four Black teachers and two White science educators’ use of photonarratives to envision culturally relevant science pedagogy. Two questions guided the study: (1) What community referents are important for conceptualizing culturally relevant practices in Black science classrooms? and (2) How do teachers’ photonarratives serve to open conversations and notions of culturally relevant science practices? The research methodologically drew upon memory-work, Black feminism, critical theory, visual methodology, and narrative inquiry as “portraiture.” Issues of positionality and identity proved to be central to this work, as three luminaries portray Black teachers’ insights about supports and barriers to teaching and learning science. The community referents identified were associated with church and its oral traditions, inequities of the market place in meeting their basic human needs, and community spaces.

When a Stone Tries to Climb up a Slope: The Interplay between Lexical and Perceptual Animacy in Referential Choices

PubMed Central

Vogels, Jorrig; Krahmer, Emiel; Maes, Alfons

2013-01-01

Several studies suggest that referential choices are influenced by animacy. On the one hand, animate referents are more likely to be mentioned as subjects than inanimate referents. On the other hand, animate referents are more frequently pronominalized than inanimate referents. These effects have been analyzed as effects of conceptual accessibility. In this paper, we raise the question whether these effects are driven only by lexical concepts, such that referents described by animate lexical items (e.g., “toddler”) are more accessible than referents described by inanimate lexical items (e.g., “shoe”), or can also be influenced by context-derived conceptualizations, such that referents that are perceived as animate in a particular context are more accessible than referents that are not. In two animation-retelling experiments, conducted in Dutch, we investigated the influence of lexical and perceptual animacy on the choice of referent and the choice of referring expression. If the effects of animacy are context-dependent, entities that are perceived as animate should yield more subject references and more pronouns than entities that are perceived as inanimate, irrespective of their lexical animacy. If the effects are tied to lexical concepts, entities described with animate lexical items should be mentioned as the subject and pronominalized more frequently than entities described with inanimate lexical items, irrespective of their perceptual animacy. The results show that while only lexical animacy appears to affect the choice of subject referent, perceptual animacy may overrule lexical animacy in the choice of referring expression. These findings suggest that referential choices can be influenced by conceptualizations based on the perceptual context. PMID:23554600

The hypercorrection effect in younger and older adults.

PubMed

Eich, Teal S; Stern, Yaakov; Metcalfe, Janet

2013-01-01

ABSTRACT The hypercorrection effect, which refers to the finding that errors committed with high confidence are more likely to be corrected than are low confidence errors, has been replicated many times, and with both young adults and children. In the present study, we contrasted older with younger adults. Participants answered general-information questions, made confidence ratings about their answers, were given corrective feedback, and then were retested on questions that they had gotten wrong. While younger adults showed the hypercorrection effect, older adults, despite higher overall accuracy on the general-information questions and excellent basic metacognitive ability, showed a diminished hypercorrection effect. Indeed, the correspondence between their confidence in their errors and the probability of correction was not significantly greater than zero, showing, for the first time, that a particular participant population is selectively impaired on this error correction task. These results potentially offer leverage both on the mechanisms underlying the hypercorrection effect and on reasons for older adults' memory impairments, as well as on memory functions that are spared.

Attentiveness of pediatricians to primary immunodeficiency disorders

PubMed Central

2012-01-01

Background Primary immunodeficiency (PID) is a cluster of serious disorders that requires special alertness on the part of the medical staff for prompt diagnosis and management of the patient. This study explored PID knowledge and experience among pediatricians of wide educational backgrounds, practicing in the United Arab Emirates (UAE). Method A self-administered questionnaire was used to determine the competency of pediatricians in their knowledge of PID disorders. This study questionnaire included questions on PID signs and symptoms, syndromes associated with immunodeficiency, screening tests, interpreting laboratory tests and case management. The participants were 263 pediatricians of diverse education working in the 27 governmental hospitals in all regions of UAE. Results The overall performance of the pediatricians did not differ based on their age, gender, origin of certification, rank, or years of experience. Of the 50 questions, 20% of pediatricians answered correctly <60% of the questions, 76% answered correctly 60 to 79% of the questions, and 4% answered correctly ≥80% of the questions. Seventeen of the 19 PID signs and symptoms were identified by 55 to 97%. Four of 5 syndromes associated with immunodeficiency were identified by 50 to 90%. Appropriate screening tests were chosen by 64 to 96%. Attention to the laboratory reference range values as function of patient age was notably limited. Conclusions There was a noteworthy deficiency in PID work-up. Therefore, implementing effective educational strategies is needed to improve the competency of pediatricians to diagnose and manage PID disorders. PMID:22846098

Real-time or quantitative PCR (qPCR) is a useful technique that requires reliable reference genes for data normalization in gene expression analysis. Adipogenesis is among the biological processes suitable for this technique. The selection of adequate reference genes is essential for qPCR gene expression analysis of human Vascular Stromal Cells (hVSCs) during their differentiation into adipocytes. To the best of our knowledge, there are no studies validating reference genes for the analyses of visceral and subcutaneous adipose tissue hVSCs from subjects with different Body Mass Index (BMI) and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index. The present study was undertaken to analyze this question. We first analyzed the stability of expression of five potential reference genes: CYC, GAPDH, RPL13A, EEF1A1, and 18S ribosomal RNA, during in vitro adipogenic differentiation, in samples from these types of patients. The expression of RPL13A and EEF1A1 was not affected by differentiation, thus being these genes the most stable candidates, while CYC, GAPDH, and 18S were not suitable for this sort of analysis. This work highlights that RPL13A and EEF1A1 are good candidates as reference genes for qPCR analysis of hVSCs differentiation into adipocytes from subjects with different BMI and HOMA-IR.

Law in everyday life and death: a socio-legal study of chronic disorders of consciousness

PubMed Central

Halliday, Simon; Kitzinger, Celia; Kitzinger, Jenny

2015-01-01

This paper addresses, from a socio-legal perspective, the question of the significance of law for the treatment, care and the end-of-life decision making for patients with chronic disorders of consciousness. We use the phrase ‘chronic disorders of consciousness’ as an umbrella term to refer to severely brain-injured patients in prolonged comas, vegetative or minimally conscious states. Based on an analysis of interviews with family members of patients with chronic disorders of consciousness, we explore the images of law that were drawn upon and invoked by these family members when negotiating the situation of their relatives, including, in some cases, the ending of their lives. By examining ‘legal consciousness’ in this way (an admittedly confusing term in the context of this study,) we offer a distinctly sociological contribution to the question of how law matters in this particular domain of social life.

2016-10-01

The New Zealand Ministry of Health responded to community concern about dioxin exposure during on-site remediation of a pesticide-contaminated rural area by commissioning this exposed-referent study of serum dioxins and health in local residents. All 200 residents were eligible, with age and sex matching to demographically comparable referents. Face-to-face interviews included questions on health status, health-related quality of life (HRQOL) and perceptions about community consultation. Thirty serum samples were obtained, eligibility being based on likelihood of exposure and age. Both HRQOL and serum outcomes were analysed by the appropriate regression methods. Of 200 eligible residents, 139 (69.5%) participated, with 139 matched referents. Mapua residents had lower physical and psychological HRQOL scores, but no difference in health status. 2,3,7,8 TCDD was below the limit of detection in the majority of all serum samples, with some congeners being higher in referents. Perceptions of the communication process were equivocal. Both dioxin levels and measures of health did not differ significantly between the exposed community and controls. Implications for public health: The results suggest neither significant dioxin exposure nor community health effects. Oversight by expert panel with health expertise, allied to sound communication, may have helped the community understand the risks. © 2016 Public Health Association of Australia.

The uses of available record systems in epidemiologic studies of reproductive toxicology are described with reference to New York State. The available record systems (and relevant reproductive end points) described include: a newborn screening program for metabolic diseases and hemoglobinopathies (relevant to point mutations); chromosome registries and prenatal cytogenetics (for chromosome anomalies); live birth certificates (for birth defects, birthweight, sex ratio, etc); fetal death certificates (for spontaneous fetal deaths); and a statewide cancer registry (for childhood cancers and transplacental carcinogenesis). The uses and limitations of these record systems are discussed, along with examples of their use in descriptive and analyticmore » epidemiologic studies. Descriptive studies outlined include investigations of temporal and geographic trends in birth defects, birth weight, and fetal deaths, with reference to environmental questions (eg, Love Canal, nuclear power plants). Analytic studies described concern parental occupation in relation to specific birth defects (neural tube defects and Down syndrome) and maternal use of contraceptive drugs.« less

This study purposes to describe and analyse the students' concept understanding of dynamic fluid. The subjects of this research are 10 students of senior high school. The data collected finished the essay test that consists of 5 questions have been adapted to the indicators of learning. The data of this research is analysed using descriptive-qualitative approach by referring of the student's argumentations about their answer from the questions that given. The results showed that students still have incorrect understanding the concept of dynamic fluids, especially on the Bernoulli’s principle and its application. Based on the results of this research, the teachers should emphasize the concept understanding of the students therefore the students don not only understand the physics concept in mathematical form.

Air medical referring customer satisfaction: a valuable insight.

PubMed

Fultz, J H; Coyle, C B; Reynolds, P W

1998-01-01

To remain competitive and survive, air medical programs must have a mechanism for obtaining customer feedback, especially when alternate transport options are available. The goal of this survey was to examine the air medical service's performance as perceived by customers requesting the transport. Surveys were mailed to 400 referring customers who had contact with the flight crew during the transition of patient care. The survey consisted of 16 statements evaluating the service by using a 4-point Likert scale, three demographic questions, one statement evaluating overall satisfaction, and two open-ended questions for comments or suggestions. Two hundred forty-four surveys were returned for a 61% responses rate. Results indicated referring customers are satisfied with the service provided Written comments and suggestions were divided into two categories, positive comments and suggestions for improvement. Three common themes were identified within the suggestions for improvement: crew rapport, communications, and operations. Suggested improvements were evaluated, and selected strategies were incorporated into program operation. Customer feedback furnishes valuable insight into their needs and perception of a service. Comments and suggestions for improvement can promote critical inquiry into service operation and provide a catalyst for improvement.

Dose–response association of screen time-based sedentary behaviour in children and adolescents and depression: a meta-analysis of observational studies

PubMed Central

Liu, Mingli; Wu, Lang; Yao, Shuqiao

2016-01-01

Background Depression represents a growing public health burden. Understanding how screen time (ST) in juveniles may be associated with risk of depression is critical for the development of prevention and intervention strategies. Findings from studies addressing this question thus far have been inconsistent. Therefore, we conducted a comprehensive systematic review and meta-analysis of data related to this question. Methods The meta-analysis was conducted in accordance with the PRISMA guideline. We searched the electronic databases of PubMed, Web of Science and EBSCO systematically (up to 6 May 2015). OR was adopted as the pooled measurement of association between ST and depression risk. Dose–response was estimated by a generalised least squares trend estimation. Results Twelve cross-sectional studies and four longitudinal studies (including 1 cohort study) involving a total of 127 714 participants were included. Overall, higher ST in preadolescent children and adolescents was significantly associated with a higher risk of depression (OR=1.12; 95% CI 1.03 to 1.22). Screen type, age, population and reference category acted as significant moderators. Compared with the reference group who had no ST, there was a non-linear dose–response association of ST with a decreasing risk of depression at ST<2 h/day, with the lowest risk being observed for 1 h/day (OR=0.88; 95% CI 0.84 to 0.93). Conclusions Our meta-analysis suggests that ST in children and adolescents is associated with depression risk in a non-linear dose–response manner. PMID:26552416

Effects of a cost-effective surgical workflow on cosmesis and patient's satisfaction in open thyroid surgery.

2013-01-01

In thyroid surgery, minimally invasive procedures are thought to improve cosmesis and patient's satisfaction. However, studies using standardized tools are scarce, and results are controversial. Moreover, minimally invasive techniques raise the question of material costs in a context of health spending cuts. The aim of the present study is to test a cost-effective surgical workflow to improve cosmesis in conventional open thyroid surgery. Our study ran between January 2009 and November 2010, and was based on a prospectively maintained thyroid surgery register. Patients operated for benign thyroid diseases were included. Since January 2010, a standardized surgical workflow was used in addition to the reference open procedure to improve the outcome. Two groups were created: (1) G1 group (patients operated with the reference technique), (2) G2 group (patients operated with our workflow in addition to reference technique). Patients were investigated for postoperative outcomes, self-evaluated body image, cosmetic and self-confidence scores. 820 patients were included in the present study. The overall body image and cosmetic scores were significantly better in the G2 group (P < 0.05). No significant difference was noted in terms of surgical outcomes, scar length, and self-confidence. Our surgical workflow in conjunction with the reference technique is safe and shows significant better results in terms of body image and cosmesis than do the reference technique alone. Thus, we recommend its implementation in order to improve outcomes in a cost-effective way. The limitations of the present study should be kept in mind in the elaboration of future studies.

Insertion torque recordings for the diagnosis of contact between orthodontic mini-implants and dental roots: a systematic review.

PubMed

Meursinge Reynders, Reint; Ladu, Luisa; Ronchi, Laura; Di Girolamo, Nicola; de Lange, Jan; Roberts, Nia; Plüddemann, Annette

2016-03-31

Most orthodontic mini-implants (OMIs) are inserted between dental roots. The prevalence of contacting these structures is high. Such contacts can cause permanent root damage and implant instability. Increased torque levels during implant insertion (the index test) could be a more accurate and immediate measure for diagnosing implant-root contact (the target condition) than radiographs (the reference standard) and could ultimately lead to a reduction or elimination of X-ray exposure. To address this issue, we asked three questions: (1) whether OMIs with root contact had higher insertion torque values than those without, (2) what is the accuracy of the index test compared with the reference standard to diagnose the target condition and what are the adverse effects of the index test, and (3) whether intermediate torque values have clinical diagnostic utility. Methods were conducted according to our published protocol, which was based on the PRISMA-P 2015 statement. We applied broad spectrum eligibility criteria that included randomized and non-randomized studies on clinical, animal, and cadaver models. Not including such models would be unethical because it could slow down knowledge creation on the adverse effects of implant insertion. We conducted searches in more than 40 electronic databases including MEDLINE and 10 journals were hand-searched. Grey literature and reference lists were also searched. All research procedures were conducted independently by three reviewers. Authors of selected studies were contacted to obtain additional information. Outcomes on the three different research models were analysed separately. Systematic error was assessed with the Cochrane 'Risk of bias tool' for non-randomized studies. One clinical, two animal, and two cadaver studies fulfilled the eligibility criteria of the first research question. All studies and subgroups demonstrated higher insertion torque values for OMIs with the target condition than those without. Mean differences (MD) between these effect estimates were statistically significant in one beagle model (MD, 4.64; 95 % CI, 3.50 to 5.79) and three subgroups of cadaver studies (MD, 2.70; 95 % CI, 1.42 to 3.98) (MD, 3.97; 95 % CI, 2.17 to 5.78) (MD, 0.93; 95 % CI, 0.67 to 1.20). Highest mean differences were identified in most self-drilling compared with pre-drilling groups. Clinical heterogeneity between studies was high, and many items were underreported. All studies except one cadaver study scored at least one domain as 'serious risk' of bias. No studies addressed the second research question. One cadaver study addressed the third question which showed the importance of recording torque levels during the entire implant insertion process. Responses of contacted authors were helpful, but often difficult to obtain. Implants fractured in one animal and in one cadaver model. All eligible studies scored higher insertion torque values for implants with root contact than those without, but none of these studies assessed the diagnostic accuracy of the index test. The inclusion of non-randomized and animal and cadaver models in this systematic review provided key findings that otherwise would have been wasted. Such studies are important in the context of the wide applicability of this test, the high prevalence of the target condition, and the underreporting of adverse effects of interventions. A protocol for a potential new diagnostic pathway was presented, and the importance of contacting authors was addressed. The applicability of the findings should be interpreted in the context of underreporting and the many limitations of the included studies.

Agreement between diagnoses reached by clinical examination and available reference standards: a prospective study of 216 patients with lumbopelvic pain

PubMed Central

Laslett, Mark; McDonald, Barry; Tropp, Hans; Aprill, Charles N; Öberg, Birgitta

2005-01-01

Background The tissue origin of low back pain (LBP) or referred lower extremity symptoms (LES) may be identified in about 70% of cases using advanced imaging, discography and facet or sacroiliac joint blocks. These techniques are invasive and availability varies. A clinical examination is non-invasive and widely available but its validity is questioned. Diagnostic studies usually examine single tests in relation to single reference standards, yet in clinical practice, clinicians use multiple tests and select from a range of possible diagnoses. There is a need for studies that evaluate the diagnostic performance of clinical diagnoses against available reference standards. Methods We compared blinded clinical diagnoses with diagnoses based on available reference standards for known causes of LBP or LES such as discography, facet, sacroiliac or hip joint blocks, epidurals injections, advanced imaging studies or any combination of these tests. A prospective, blinded validity design was employed. Physiotherapists examined consecutive patients with chronic lumbopelvic pain and/or referred LES scheduled to receive the reference standard examinations. When diagnoses were in complete agreement regardless of complexity, "exact" agreement was recorded. When the clinical diagnosis was included within the reference standard diagnoses, "clinical agreement" was recorded. The proportional chance criterion (PCC) statistic was used to estimate agreement on multiple diagnostic possibilities because it accounts for the prevalence of individual categories in the sample. The kappa statistic was used to estimate agreement on six pathoanatomic diagnoses. Results In a sample of chronic LBP patients (n = 216) with high levels of disability and distress, 67% received a patho-anatomic diagnosis based on available reference standards, and 10% had more than one tissue origin of pain identified. For 27 diagnostic categories and combinations, chance clinical agreement (PCC) was estimated at 13%. "Exact" agreement between clinical and reference standard diagnoses was 32% and "clinical agreement" 51%. For six pathoanatomic categories (disc, facet joint, sacroiliac joint, hip joint, nerve root and spinal stenosis), PCC was 33% with actual agreement 56%. There was no overlap of 95% confidence intervals on any comparison. Diagnostic agreement on the six most common patho-anatomic categories produced a kappa of 0.31. Conclusion Clinical diagnoses agree with reference standards diagnoses more often than chance. Using available reference standards, most patients can have a tissue source of pain identified.

Microarray experiments have been used recently in genetical genomics studies, as an additional tool to understand the genetic mechanisms governing variation in complex traits, such as for estimating heritabilities of mRNA transcript abundances, for mapping expression quantitative trait loci, and for inferring regulatory networks controlling gene expression. Several articles on the design of microarray experiments discuss situations in which treatment effects are assumed fixed and without any structure. In the case of two-color microarray platforms, several authors have studied reference and circular designs. Here, we discuss the optimal design of microarray experiments whose goals refer to specific genetic questions. Some examples are used to illustrate the choice of a design for comparing fixed, structured treatments, such as genotypic groups. Experiments targeting single genes or chromosomic regions (such as with transgene research) or multiple epistatic loci (such as within a selective phenotyping context) are discussed. In addition, microarray experiments in which treatments refer to families or to subjects (within family structures or complex pedigrees) are presented. In these cases treatments are more appropriately considered to be random effects, with specific covariance structures, in which the genetic goals relate to the estimation of genetic variances and the heritability of transcriptional abundances.

Research ends when the results are shared in the academic and professional community, and for this reason they need to be published in scientific journals of reference. But the question is where should the results of nursing research be published? Taking into account the expanding context and scientific consolidation of the discipline. To answer this question, an analysis will be made of the benefits and the most common criticisms of the two most important multidisciplinary literature data bases, as well as examining the context of the Spanish nursing journals in these data bases. A description will also be made of the indexing systems, as well as making proposals to contribute to improved visibility of Spanish nursing research through the positioning of its journals.

Reduction of streamflow monitoring networks by a reference point approach

NASA Astrophysics Data System (ADS)

Cetinkaya, Cem P.; Harmancioglu, Nilgun B.

2014-05-01

Adoption of an integrated approach to water management strongly forces policy and decision-makers to focus on hydrometric monitoring systems as well. Existing hydrometric networks need to be assessed and revised against the requirements on water quantity data to support integrated management. One of the questions that a network assessment study should resolve is whether a current monitoring system can be consolidated in view of the increased expenditures in time, money and effort imposed on the monitoring activity. Within the last decade, governmental monitoring agencies in Turkey have foreseen an audit on all their basin networks in view of prevailing economic pressures. In particular, they question how they can decide whether monitoring should be continued or terminated at a particular site in a network. The presented study is initiated to address this question by examining the applicability of a method called “reference point approach” (RPA) for network assessment and reduction purposes. The main objective of the study is to develop an easily applicable and flexible network reduction methodology, focusing mainly on the assessment of the “performance” of existing streamflow monitoring networks in view of variable operational purposes. The methodology is applied to 13 hydrometric stations in the Gediz Basin, along the Aegean coast of Turkey. The results have shown that the simplicity of the method, in contrast to more complicated computational techniques, is an asset that facilitates the involvement of decision makers in application of the methodology for a more interactive assessment procedure between the monitoring agency and the network designer. The method permits ranking of hydrometric stations with regard to multiple objectives of monitoring and the desired attributes of the basin network. Another distinctive feature of the approach is that it also assists decision making in cases with limited data and metadata. These features of the RPA approach highlight its advantages over the existing network assessment and reduction methods.

To evaluate the interobserver agreement between physicians regarding a abnormal cardiovascular assessment on athletic preparticipation examinations. Cross-sectional clinical survey. Outpatient Clinic, United States Military Academy, West Point, NY. We randomly selected 101 out of 539 cadet-athletes presenting for a preparticipation examination. Two primary care sports medicine fellows and a cardiologist examined the cadets. After obtaining informed consent from all participants, all 3 physicians separately evaluated all 101 cadets. The physicians recorded their clinical findings and whether they thought further cardiovascular evaluation (echocardiography) was indicated. Rate of referral for further cardiovascular evaluation, clinical agreement between sports medicine fellows, and clinical agreement between sports medicine fellows and the cardiologist. Each fellow referred 6 of the 101 evaluated cadets (5.9%). The cardiologist referred none. Although each fellow referred 6 cadets, only 1 cadet was referred by both. The kappa statistic for clinical agreement between fellows is 0.114 (95% CI, -0.182 to 0.411). There was no clinical agreement between the fellows and the cardiologist. This pilot study reveals a low level of agreement between physicians regarding which athletes with an abnormal examination deserved further testing. It challenges the standard of care and questions whether there is a need for improved technologies or improved training in cardiovascular clinical assessment.

A comparison of five methodological variants of emoji questionnaires for measuring product elicited emotional associations: An application with seafood among Chinese consumers.

Product insights beyond hedonic responses are increasingly sought and include emotional associations. Various word-based questionnaires for direct measurement exist and an emoji variant was recently proposed. Herein, emotion words are replaced with emoji conveying a range of emotions. Further assessment of emoji questionnaires is needed to establish their relevance in food-related consumer research. Methodological research contributes hereto and in the present research the effects of question wording and response format are considered. Specifically, a web study was conducted with Chinese consumers (n=750) using four seafood names as stimuli (mussels, lobster, squid and abalone). Emotional associations were elicited using 33 facial emoji. Explicit reference to "how would you feel?" in the question wording changed product emoji profiles minimally. Consumers selected only a few emoji per stimulus when using CATA (check-all-that-apply) questions, and layout of the CATA question had only a small impact on responses. A comparison of CATA questions with forced yes/no questions and RATA (rate-all-that-apply) questions revealed an increase in frequency of emoji use for yes/no questions, but not a corresponding improvement in sample discrimination. For the stimuli in this research, which elicited similar emotional associations, RATA was probably the best methodological choice, with 8.5 emoji being used per stimulus, on average, and increased sample discrimination relative to CATA (12% vs. 6-8%). The research provided additional support for the potential of emoji surveys as a method for measurement of emotional associations to foods and beverages and began contributing to development of guidelines for implementation.

To determine the diagnostic performances of several single question delirium screens. To the patient we asked: "Have you had any difficulty thinking clearly lately?" To the patient's surrogate, we asked: "Is the patient at his or her baseline mental status?" and "Have you noticed the patient's mental status fluctuate throughout the course of the day?" This was a prospective observational study that enrolled English speaking patients 65 years or older. A research assistant (RA) and emergency physician (EP) independently asked the patient and surrogate the single question delirium screens. The reference standard for delirium was a consultation-liaison psychiatrist's assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria. All assessments were performed within 3 h and were all blinded to each other. Of the 406 patients enrolled, 50 (12%) were delirious. A patient who was unable to answer the question "Have you had any difficulty thinking clearly lately?" was 99.7% (95% CI: 98.0%-99.9%) specific, but only 24.0% (95% CI: 14.3%-37.4%) sensitive for delirium when asked by the RA. The baseline mental status surrogate question was 77.1% (95% CI: 61.0%-87.9%) sensitive and 87.5% (95% CI: 82.8%-91.1%) specific for delirium when asked by the RA. The fluctuating course surrogate question was 77.1% (95% CI: 61.0%-87.9%) sensitive and 80.2% (95% CI: 74.8%-84.7%) specific. When asked by the EP, the single question delirium screens' diagnostic performances were similar. The patient and surrogate single question delirium assessments may be useful for delirium screening in the ED. Copyright © 2018. Published by Elsevier Inc.

Introduction Panic disorder is a common anxiety disorder and is highly prevalent in Spanish primary care centres. The use of validated tools can improve the detection of panic disorder in primary care populations, thus enabling referral for specialized treatment. The aim of this study is to determine the accuracy of the Patient Health Questionnaire-Panic Disorder (PHQ-PD) as a screening and diagnostic tool for panic disorder in Spanish primary care centres. Method We compared the psychometric properties of the PHQ-PD to the reference standard, the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) interview. General practitioners referred 178 patients who completed the entire PHQ test, including the PHQ-PD, to undergo the SCID-I. The sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios of the PHQ-PD were assessed. Results The operating characteristics of the PHQ-PD are moderate. The best cut-off score was 5 (sensitivity .77, specificity .72). Modifications to the questionnaire's algorithms improved test characteristics (sensitivity .77, specificity .72) compared to the original algorithm. The screening question alone yielded the highest sensitivity score (.83). Conclusion Although the modified algorithm of the PHQ-PD only yielded moderate results as a diagnostic test for panic disorder, it was better than the original. Using only the first question of the PHQ-PD showed the best psychometric properties (sensitivity). Based on these findings, we suggest the use of the screening questions for screening purposes and the modified algorithm for diagnostic purposes. PMID:27525977

Abstract Objective To determine the sexual and reproductive health priorities of women living with human immunodeficiency virus (HIV) and to allow the values and preferences of such women to be considered in the development of new guidelines. Methods A core team created a global reference group of 14 women living with HIV and together they developed a global community online survey. The survey, which contained mandatory and optional questions, was based on an appreciative enquiry approach in which the life-cycle experiences of women living with HIV were investigated. The same set of questions was also used in focus group discussions led by the global reference group. Findings The study covered 945 women (832 in the survey and 113 in the focus groups) aged 15–72 years in 94 countries. Among the respondents to the optional survey questions, 89.0% (427/480) feared or had experienced gender-based violence, 56.7% (177/312) had had an unplanned pregnancy, 72.3% (227/314) had received advice on safe conception and 58.8% (489/832) had suffered poor mental health after they had discovered their HIV-positive status. Conclusion The sexual and reproductive health needs and rights of women living with HIV are complex and require a stronger response from the health sector. The online survey placed the voices of women living with HIV at the start of the development of new global guidelines. Although not possible in some contexts and populations, a similar approach would merit replication in the development of guidelines for many other health considerations. PMID:27034517

It is difficult to validate statistical software used to assess bioequivalence since very few datasets with known results are in the public domain, and the few that are published are of moderate size and balanced. The purpose of this paper is therefore to introduce reference datasets of varying complexity in terms of dataset size and characteristics (balance, range, outlier presence, residual error distribution) for 2-treatment, 2-period, 2-sequence bioequivalence studies and to report their point estimates and 90% confidence intervals which companies can use to validate their installations. The results for these datasets were calculated using the commercial packages EquivTest, Kinetica, SAS and WinNonlin, and the non-commercial package R. The results of three of these packages mostly agree, but imbalance between sequences seems to provoke questionable results with one package, which illustrates well the need for proper software validation.

The WFIRST Interim Design Reference Mission: Capabilities, Constraints, and Open Questions

Kruk, Jeffrey W.

2012-01-01

The Project Office and Science Definition Team for the Wide-Field Infrared Survey Telescope (WFIRST) are in the midst of a pre-Phase A study to establish a Design Reference Mission (DRM). An Interim report was released in June 2011, with a final report due later in 2012. The predicted performance of the Interim DRM Observatory will be described, including optical quality, observing efficiency, and sensitivity for representative observing scenarios. Observing constraints and other limitations on performance will also be presented, with an emphasis on potential Guest Observer programs. Finally, a brief status update will be provided on open trade studies of interest to the scientific community. The final DRM may differ from the Interim DRM presented here. However, the underlying requirements of the scientific programs are not expected to change, hence the capabilities of the IDRM are likely to be maintained even if the implementation changes in significant ways.

Collaborative study to evaluate a new ELISA test to monitor the effectiveness of rabies vaccination in domestic carnivores.

PubMed

Servat, A; Cliquet, F

2006-09-01

To prevent any introduction of rabies, many rabies-free countries have adopted a scheme requiring the rabies vaccination of pets associated with a serological test. FAVN test and RFFIT are the current OIE prescribed techniques to perform this assay. A qualitative indirect ELISA (Serelisa) test has been recently described as a screening test to monitor the effectiveness of rabies vaccination of pets. A lack of sensitivity requires ELISA negative samples to be retested using an OIE confirmatory test. This raised the question whether this new test could be reasonably proposed as an alternative tool in the context of international trades of pets. The Community Reference Institute of Nancy organized a short trial to answer this question. In this study, 16 laboratories tested a panel of their own samples with FAVN test/RFFIT and the Serelisa. The comparison of results revealed that the performance of the Serelisa is highly heterogeneous. A lack of sensitivity was detected in 50% of participants, when 25% of laboratories obtained a significant rate of false positive results. This last point questions the pertinence of using the Serelisa in the context of international trades by preventing any movements of insufficiently or non-protected animals.

Contents 34 I. 34 II. 36 III. 37 IV. 37 V. 38 38 References 38 SUMMARY: Characterizing plant responses to past, present and future changes in atmospheric carbon dioxide concentration ([CO 2 ]) is critical for understanding and predicting the consequences of global change over evolutionary and ecological timescales. Previous CO 2 studies have provided great insights into the effects of rising [CO 2 ] on leaf-level gas exchange, carbohydrate dynamics and plant growth. However, scaling CO 2 effects across biological levels, especially in field settings, has proved challenging. Moreover, many questions remain about the fundamental molecular mechanisms driving plant responses to [CO 2 ] and other global change factors. Here we discuss three examples of topics in which significant questions in CO 2 research remain unresolved: (1) mechanisms of CO 2 effects on plant developmental transitions; (2) implications of rising [CO 2 ] for integrated plant-water dynamics and drought tolerance; and (3) CO 2 effects on symbiotic interactions and eco-evolutionary feedbacks. Addressing these and other key questions in CO 2 research will require collaborations across scientific disciplines and new approaches that link molecular mechanisms to complex physiological and ecological interactions across spatiotemporal scales. © 2016 The Authors.

Mendel in the Modern Classroom

Smith, Mike U.; Gericke, Niklas M.

2015-01-01

Mendel is an icon in the history of genetics and part of our common culture and modern biology instruction. The aim of this paper is to summarize the place of Mendel in the modern biology classroom. In the present article we will identify key issues that make Mendel relevant in the classroom today. First, we recount some of the historical controversies that have relevance to modern curricular design, such as Fisher's (Ann Sci 1:115-137, 1936/2008) claim that Mendel's data were too good to be true. We also address questions about Mendel's status as the father of genetics as well as questions about the sequencing of Mendel's work in genetics instruction in relation to modern molecular genetics and evolution. Next, we present a systematic set of examples of research based approaches to the use of Mendel in the modern classroom along with criticisms of these designs and questions about the historical accuracy of the story of Mendel as presented in the typical classroom. Finally, we identify gaps in our understanding in need of further study and present a selected set of resources that, along with the references cited, should be valuable to science educators interested in further study of the story of Mendel.

Human-tissue-related inventions: ownership and intellectual property rights in international collaborative research in developing countries.

PubMed

Andanda, P A

2008-03-01

There are complex unresolved ethical, legal and social issues related to the use of human tissues obtained in the course of research or diagnostic procedures and retained for further use in research. The question of intellectual property rights over commercially viable products or procedures that are derived from these samples and the suitability or otherwise of participants relinquishing their rights to the samples needs urgent attention. The complexity of these matters lies in the fact that the relationship between intellectual property rights and ownership or rights pertaining to the samples on which the intellectual property right is based may either be overlooked or taken for granted. What equally makes the matter complex is that samples may be obtained from participants in developing countries and exported to developed countries for analysis and research. It is important for research ethics committees to tread carefully when reviewing research protocols that raise such issues for purposes of ensuring that appropriate benefit sharing agreements, particularly with developing countries, are in place. This paper attempts to analyse the key questions related to ownership and intellectual property rights in commercially viable products derived from human tissue samples. Patent law is used as a point of reference as opposed to other forms of intellectual property rights such as industrial designs because it is the right that most inventors apply for in respect of human tissue-related inventions. The key questions are formulated following a systematic analysis of peer reviewed journal articles that have reported original investigations into relevant issues in this field. Most of the cases and reported studies that are referred to in this paper do not directly deal with HIV/AIDS research but the underlying principles are helpful in HIV/AIDS research as well. Pertinent questions, which members of ethics review committees should focus on in this regard are discussed and suggestions on appropriate approaches to the issues are proposed in the form of specific questions that an ethics review committee should consider. Specific recommendations regarding areas for further research and action are equally proposed.

Martian Chemical and Isotopic Reference Standards in Earth-based Laboratories — An Invitation for Geochemical, Astrobiological, and Engineering Dialog on Considering a Weathered Chondrite for Mars Sample Return.

Exogenic rocks (meteorites) found on Mars 1) have unweathered counterparts on Earth; 2) weather differently than indigenous rocks; and 3) may be ideal habitats for putative microorganisms and subsequent biosignature preservation. These attributes show the potential of meteorites for addressing hypothesis-driven science. They raise the question of whether chondritic meteorites, of sufficient weathering intensity, might be considered as candidates for sample return in a potential future mission. Pursuant to this discussion are the following questions. A) Is there anything to be learned from the laboratory study of a martian chondrite that cannot be learned from indigenous materials; and if so, B) is the science value high enough to justify recovery? If both A and B answer affirmatively, then C) what are the engineering constraints for sample collection for Mars 2020 and potential follow-on missions; and finally D) what is the likelihood of finding a favorable sample? Observations relevant to these questions include: i) Since 2005, 24 candidate and confirmed meteorites have been identified on Mars at three rover landing sites, demonstrating their ubiquity and setting expectations for future finds. All have been heavily altered by a variety of physical and chemical processes. While the majority of these are irons (not suitable for recovery), several are weathered stony meteorites. ii) Exogenic reference materials provide the only chemical/isotope standards on Mars, permitting quantification of alteration rates if residence ages can be attained; and possibly enabling the removal of Late Amazonian weathering overprints from other returned samples. iii) Recent studies have established the habitability of chondritic meteorites with terrestrial microorganisms, recommending their consideration when exploring astrobiological questions. High reactivity, organic content, and permeability show stony meteorites to be more attractive for colonization and subsequent biosignature preservation than Earth rocks. iv) Compressive strengths of most ordinary chondrites are within the range of rocks being tested for the Mars 2020 drill bits, provided that sufficient size, stability, and flatness of a target can be achieved. Alternatively, the regolith collection bit could be employed for unconsolidated material.

Graded Multiple Choice Questions: Rewarding Understanding and Preventing Plagiarism

Denyer, G. S.; Hancock, D.

2002-08-01

This paper describes an easily implemented method that allows the generation and analysis of graded multiple-choice examinations. The technique, which uses standard functions in user-end software (Microsoft Excel 5+), can also produce several different versions of an examination that can be employed to prevent the reward of plagarism. The manuscript also discusses the advantages of having a graded marking system for the elimination of ambiguities, use in multi-step calculation questions, and questions that require extrapolation or reasoning. The advantages of the scrambling strategy, which maintains the same question order, is discussed with reference to student equity. The system provides a non-confrontational mechanism for dealing with cheating in large-class multiple-choice examinations, as well as providing a reward for problem solving over surface learning.

The present study investigates the arguments used by university students in order to explain social differences between social minorities and majorities. In Brazil, the issues investigated refer to White and Black people. In Spain, the reference is to native Spaniards and Moroccan immigrants. The participants were 144 Brazilians and 93 Spaniards, who answered a questionnaire composed of socio-demographic variables and one open question about the causes of social inequalities between Black and White people in Brazil and between autochthonous Spaniards and Moroccan Immigrants. A model is proposed to integrate the four discursive classes found using ALCESTE software. In Brazil, the strongest argument is based on the historical roots of the exploitation of Black people. In Spain, cultural differences are the main explanation for social inequalities.

Estimating the Geocenter from GNSS Observations

NASA Astrophysics Data System (ADS)

Dach, Rolf; Michael, Meindl; Beutler, Gerhard; Schaer, Stefan; Lutz, Simon; Jäggi, Adrian

2014-05-01

The satellites of the Global Navigation Satellite Systems (GNSS) are orbiting the Earth according to the laws of celestial mechanics. As a consequence, the satellites are sensitive to the coordinates of the center of mass of the Earth. The coordinates of the (ground) tracking stations are referring to the center of figure as the conventional origin of the reference frame. The difference between the center of mass and center of figure is the instantaneous geocenter. Following this definition the global GNSS solutions are sensitive to the geocenter. Several studies demonstrated strong correlations of the GNSS-derived geocenter coordinates with parameters intended to absorb radiation pressure effects acting on the GNSS satellites, and with GNSS satellite clock parameters. One should thus pose the question to what extent these satellite-related parameters absorb (or hide) the geocenter information. A clean simulation study has been performed to answer this question. The simulation environment allows it in particular to introduce user-defined shifts of the geocenter (systematic inconsistencies between the satellite's and station's reference frames). These geocenter shifts may be recovered by the mentioned parameters - provided they were set up in the analysis. If the geocenter coordinates are not estimated, one may find out which other parameters absorb the user-defined shifts of the geocenter and to what extent. Furthermore, the simulation environment also allows it to extract the correlation matrix from the a posteriori covariance matrix to study the correlations between different parameter types of the GNSS analysis system. Our results show high degrees of correlations between geocenter coordinates, orbit-related parameters, and satellite clock parameters. These correlations are of the same order of magnitude as the correlations between station heights, troposphere, and receiver clock parameters in each regional or global GNSS network analysis. If such correlations are accepted in a GNSS analysis when estimating station coordinates, geocenter coordinates must be considered as mathematically estimable in a global GNSS analysis. The geophysical interpretation may of course become difficult, e.g., if insufficient orbit models are used.

In 1963, the Nobel Prize-winning ethologist Niko Tinbergen proposed a framework for the scientific study of animal behaviour by outlining four questions that should be answered to have a complete understanding: causation, ontogeny, function and evolution. At present, Tinbergen's framework is still considered the best way to guide animal behavioural research. Given the importance in science instruction of demonstrating how scientists work and ask questions, we investigated to what extent Tinbergen's questions are addressed in biology textbooks in secondary education in Flanders, Belgium, and represented in upper-secondary and first-year university students' explanations of behaviour in general and of specific animal behaviours. Our results revealed that teaching of animal behaviour mainly addresses ontogeny and causation, and that Tinbergen's framework is not explicitly referred to. Students typically addressed only one or two questions, with the majority addressing causation or both causation and ontogeny when explaining behaviour in general, but function or causation and function when explaining specific animal behaviours. This high prevalence of function may be due to teleological thinking. Evolution was completely neglected, even in university students who had recently completed an evolution course. Our results revealed that transfer of the concepts of ontogeny and evolution was (almost) absent. We argue why Tinbergen's framework should be an integral part of any biology curriculum.

Non-adherence to the treatment of chronic diseases such as hypertension and Diabetes Mellitus (DM) is a major obstacle in achieving patient therapy targets and quality of life of patients. A comprehensive approach involving pharmacists counselling has shown influences on changes in health behaviour and patient compliance. Behaviour changes in patients are one of the parameters to assess the effectiveness of counselling and education by pharmacists. Therefore, it is necessary to develop questionnaires of behaviour change measurement in DM-hypertension patients. This study aims to develop a measurement instrument in the form of questionnaires in assessing the behaviour change of DM-hypertension patients. Preparation of question items from the questionnaire research instrument refers to some guidelines and previous research references. Test of questionnaire instrument valid was done with expert validation, followed by pilot testing on 10 healthy respondents, and 10 DM-hypertension patients included in the inclusion criteria. Furthermore, field validation test was conducted on 37 patients who had undergone outpatient care at the PKU Muhammadiyah Yogyakarta City Hospital and The Gading Clinic in Yogyakarta. The inclusion criteria were male and female patients, aged 18-65, diagnosed with type 2 diabetes with hypertension who received oral antidiabetic drugs and antihypertensives, and who were not illiterate and co-operative. The data were collected by questionnaire interviews by a standardized pharmacist. The result of validation test using Person correlation shows the value of 0.33. The results of the questionnaire validation test on 37 patients showed 5 items of invalid questions with the value of r <0.33, e: questions 2, 3, 6, 10 and 11, while the other 10 questions show the value of Pearson correlation > 0.33. The reliability value is shown from the Cronbach's alpha value of 0.722 (> 0.6), implying that the questionnaire is reliable for DM-hypertension patients. This Behavioural change questionnaire can be used on DM-hypertension patients, and an FGD approach is required for the development of factors affecting this questionnaire.

In 2013, Kobe Pharmaceutical University established "Yakugaku Nyumon", an interdisciplinary course, which consists of omnibus lectures and problem-based learning (PBL) on topics ranging from basic to clinical subjects. The themes of the PBL were original ones; "Study from package inserts of aspirin", which aimed to reinforce the contents of the interdisciplinary lectures, and "Let's think about aspirin derivatives (super-aspirin)", which aimed to engender an interest in studying pharmacy. The PBL featured questions from teachers to help with study and was therefore referred to as "question-led PBL" (Q-PBL). The Q-PBL regarding aspirin derivatives began with preparing answers to the questions for a small group discussion (SGD) as an assignment, followed by a SGD, a presentation, and peer-feedback. From an analysis of the questionnaire survey, it was found that students considered the Q-PBL satisfying and that they had achieved the 4 aims: (1) to increase the motivation to study, (2) to enhance an understanding of the relations and significance of basic and clinical sciences, (3) to comprehend the learning content, and (4) to recognize the importance of communication. The Q-PBL with assignments has two favorable points. One is that the first-year students can challenge difficult and high-level questions when they are given these as assignments. The other is that students, who are unfamiliar with SGD can engage in discussions with other students using the knowledge gained from the assignment. The introduction of omnibus lectures and Q-PBL, along with these improvements in theme, application, and review process, promises increased learning efficacy at the university.

PURPOSE The short, validated, self-administered, Case-finding and Help Assessment Tool (CHAT) for lifestyle and mental health assessment of adult patients in primary health care addresses inactivity, tobacco use, alcohol and other drug misuse, problem gambling, depression, anxiety and stress, abuse, and anger problems. For each issue patients are asked whether they would like help, either during the consultation or at a later date. This study aims to assess the value of the help question. METHODS Validation of the CHAT was conducted according to the STAndards for Reporting of Diagnostic accuracy studies statement for diagnostic tests. The setting was Auckland primary care practices with populations ranging from socioeconomically advantaged to deprived. Participants were 755 consecutive primary care patients who completed the CHAT plus the help question and reference standards. Sensitivity, specificity, and likelihood ratios with and without the addition of help the question were calculated. RESULTS Sensitivity ranged from 80% to 98% for the more-common conditions (depression, nicotine dependency, anxiety, problematic drinking). For each condition, specificity increased with the addition of the help question: depression increased from 73% to 98%; anxiety 77% to 99%; drinking 85% to 99%; verbal anger 92% to 99%; verbal abuse 97% to 99%; problematic drinking and gambling 98% to 99%. CONCLUSIONS The help question increased specificity without compromising sensitivity and reduced false positives, thereby increasing the positive predictive value. It allowed patients with comorbidities to prioritize issues they wished to address, indicate their readiness to change, promote self-determination, and give the clinician an indication of which topics to pursue.

Time and Space in Tzeltal: Is the Future Uphill?

PubMed Central

Brown, Penelope

2012-01-01

Linguistic expressions of time often draw on spatial language, which raises the question of whether cultural specificity in spatial language and cognition is reflected in thinking about time. In the Mayan language Tzeltal, spatial language relies heavily on an absolute frame of reference utilizing the overall slope of the land, distinguishing an “uphill/downhill” axis oriented from south to north, and an orthogonal “crossways” axis (sunrise-set) on the basis of which objects at all scales are located. Does this absolute system for calculating spatial relations carry over into construals of temporal relations? This question was explored in a study where Tzeltal consultants produced temporal expressions and performed two different non-linguistic temporal ordering tasks. The results show that at least five distinct schemata for conceptualizing time underlie Tzeltal linguistic expressions: (i) deictic ego-centered time, (ii) time as an ordered sequence (e.g., “first”/“later”), (iii) cyclic time (times of the day, seasons), (iv) time as spatial extension or location (e.g., “entering/exiting July”), and (v) a time vector extending uphillwards into the future. The non-linguistic task results showed that the “time moves uphillwards” metaphor, based on the absolute frame of reference prevalent in Tzeltal spatial language and thinking and important as well in the linguistic expressions for time, is not strongly reflected in responses on these tasks. It is argued that systematic and consistent use of spatial language in an absolute frame of reference does not necessarily transfer to consistent absolute time conceptualization in non-linguistic tasks; time appears to be more open to alternative construals.

We aimed to develop evidence-based multinational recommendations for the diagnosis and management of gout. Using a formal voting process, a panel of 78 international rheumatologists developed 10 key clinical questions pertinent to the diagnosis and management of gout. Each question was investigated with a systematic literature review. Medline, Embase, Cochrane CENTRAL and abstracts from 2010–2011 European League Against Rheumatism and American College of Rheumatology meetings were searched in each review. Relevant studies were independently reviewed by two individuals for data extraction and synthesis and risk of bias assessment. Using this evidence, rheumatologists from 14 countries (Europe, South America and Australasia) developed national recommendations. After rounds of discussion and voting, multinational recommendations were formulated. Each recommendation was graded according to the level of evidence. Agreement and potential impact on clinical practice were assessed. Combining evidence and clinical expertise, 10 recommendations were produced. One recommendation referred to the diagnosis of gout, two referred to cardiovascular and renal comorbidities, six focused on different aspects of the management of gout (including drug treatment and monitoring), and the last recommendation referred to the management of asymptomatic hyperuricaemia. The level of agreement with the recommendations ranged from 8.1 to 9.2 (mean 8.7) on a 1–10 scale, with 10 representing full agreement. Ten recommendations on the diagnosis and management of gout were established. They are evidence-based and supported by a large panel of rheumatologists from 14 countries, enhancing their utility in clinical practice. PMID:23868909

Type of Evidence Behind Point-of-Care Clinical Information Products: A Bibliometric Analysis

PubMed Central

2011-01-01

Background Point-of-care (POC) products are widely used as information reference tools in the clinical setting. Although usability, scope of coverage, ability to answer clinical questions, and impact on health outcomes have been studied, no comparative analysis of the characteristics of the references, the evidence for the content, in POC products is available. Objective The objective of this study was to compare the type of evidence behind five POC clinical information products. Methods This study is a comparative bibliometric analysis of references cited in monographs in POC products. Five commonly used products served as subjects for the study: ACP PIER, Clinical Evidence, DynaMed, FirstCONSULT, and UpToDate. The four clinical topics examined to identify content in the products were asthma, hypertension, hyperlipidemia, and carbon monoxide poisoning. Four indicators were measured: distribution of citations, type of evidence, product currency, and citation overlap. The type of evidence was determined based primarily on the publication type found in the MEDLINE bibliographic record, as well as the Medical Subject Headings (MeSH), both assigned by the US National Library of Medicine. MeSH is the controlled vocabulary used for indexing articles in MEDLINE/PubMed. Results FirstCONSULT had the greatest proportion of references with higher levels of evidence publication types such as systematic review and randomized controlled trial (137/153, 89.5%), although it contained the lowest total number of references (153/2330, 6.6%). DynaMed had the largest total number of references (1131/2330, 48.5%) and the largest proportion of current (2007-2009) references (170/1131, 15%). The distribution of references cited for each topic varied between products. For example, asthma had the most references listed in DynaMed, Clinical Evidence, and FirstCONSULT, while hypertension had the most references in UpToDate and ACP PIER. An unexpected finding was that the rate of citation overlap was less than 1% for each topic across all five products. Conclusions Differences between POC products are revealed by examining the references cited in the monographs themselves. Citation analysis extended to include key content indicators can be used to compare the evidence levels of the literature supporting the content found in POC products. PMID:21335319

1978-01-01

A closed duplex DNA molecule relaxed and containing nucleosomes has a different linking number from the same molecule relaxed and without nucleosomes. What does this say about the structure of the nucleosome? A mathematical study of this question is made, representing the DNA molecule by a ribbon. It is shown that the linking number of a closed ribbon can be decomposed into the linking number of a reference ribbon plus a sum of locally determined “linking differences.” PMID:16592550

This study was conducted to document current immunization practices by family physicians. In 2008 the American Academy of Family Physicians (AAFP) conducted a survey among a random sample of 2,000 of its members who reported spending 80% or more of their time in direct patient care. The survey consisted of questions regarding the demographics of the practice, vaccines that are provided at the physicians' clinical site, whether the practice refers patients elsewhere for vaccines, and participation in the Vaccines for Children (VFC) program. The response rate was 38.5%, 31.8% after non-office-based respondents were deleted. A high proportion of respondents (80% or more) reported providing most routinely recommended child, adolescent, and adult vaccines at their practice sites. The exceptions were rotavirus vaccine for children and herpes zoster vaccine for adults., A significant proportion, however, reported referring elsewhere for some vaccines (44.1% for children and adolescent vaccines and 53.5% for adult vaccines), with the most frequent referral location being a public health department. A higher proportion of solo and 2-physician practices than larger practices reported referring patients. A lack of adequate payment was listed as the reason for referring patients elsewhere for vaccines by one-half of those who refer patients. One-half of responders do not participate in the VFC program. Provision of recommended vaccines by most family physicians remains an important service. Smaller practices have more difficulty offering a full array of vaccine products, and lack of adequate payment contributes to referring patients outside the medical home. The reasons behind the lack of participation in the VFC program deserve further study.

WHO Environmental Noise Guidelines for the European Region: A Systematic Review on Environmental Noise and Effects on Sleep

2018-01-01

To evaluate the quality of available evidence on the effects of environmental noise exposure on sleep a systematic review was conducted. The databases PSYCINFO, PubMed, Science Direct, Scopus, Web of Science and the TNO Repository were searched for non-laboratory studies on the effects of environmental noise on sleep with measured or predicted noise levels and published in or after the year 2000. The quality of the evidence was assessed using GRADE criteria. Seventy four studies predominately conducted between 2000 and 2015 were included in the review. A meta-analysis of surveys linking road, rail, and aircraft noise exposure to self-reports of sleep disturbance was conducted. The odds ratio for the percent highly sleep disturbed for a 10 dB increase in Lnight was significant for aircraft (1.94; 95% CI 1.61–2.3), road (2.13; 95% CI 1.82–2.48), and rail (3.06; 95% CI 2.38–3.93) noise when the question referred to noise, but non-significant for aircraft (1.17; 95% CI 0.54–2.53), road (1.09; 95% CI 0.94–1.27), and rail (1.27; 95% CI 0.89–1.81) noise when the question did not refer to noise. A pooled analysis of polysomnographic studies on the acute effects of transportation noise on sleep was also conducted and the unadjusted odds ratio for the probability of awakening for a 10 dBA increase in the indoor Lmax was significant for aircraft (1.35; 95% CI 1.22–1.50), road (1.36; 95% CI 1.19–1.55), and rail (1.35; 95% CI 1.21–1.52) noise. Due to a limited number of studies and the use of different outcome measures, a narrative review only was conducted for motility, cardiac and blood pressure outcomes, and for children’s sleep. The effect of wind turbine and hospital noise on sleep was also assessed. Based on the available evidence, transportation noise affects objectively measured sleep physiology and subjectively assessed sleep disturbance in adults. For other outcome measures and noise sources the examined evidence was conflicting or only emerging. According to GRADE criteria, the quality of the evidence was moderate for cortical awakenings and self-reported sleep disturbance (for questions that referred to noise) induced by traffic noise, low for motility measures of traffic noise induced sleep disturbance, and very low for all other noise sources and investigated sleep outcomes.

Fascioliasis is a zoonotic disease of livestock and human caused by Fasciola species. Here in, the results of serological evaluation of fascioliasis in people referring to the School of Public Health, Tehran University of Medical Sciences during 2008-2014 are presented. Demographic characterizations, symptoms and eosinophil rate were registered for every patient. Using somatic antigen of Fasciola, ELISA was performed and the results were analyzed. Data of questioners were analyzed as well. Among 206 applicants, 24.8% were seropositive for fascioliasis, included 21% female and 28.3% male. Mean range of age of patients was between 13 to 67 yr. The highest rate of seropositivity was found among 20-30 yr old patients. Most of the patients had hypereosinophilia. All patients had history of eating raw vegetables, or drinking unsafe water. Patients were referring from different provinces of Iran, including Gilan, Mazandaran, Tehran, Ardabil, Khuzestan, Lorestan, North Khorasan, Kermanshah, Azerbaijan, Fars, Kordestan, Hamedan and Markazi. During recent years, variety of provinces in Iran, where patients with fascioliasis are referred, has been increased. Patients coming from Gilan and Mazandaran provinces were referred early after the onset of their symptoms. Most probably, physicians in Gilan and Mazandaran are more alert on fascioliasis than other provinces. Previous wrong diagnosis was more common among patients referring from other provinces than Gilan and Mazandaran provinces.

Objectives Considering equity into guidelines presents methodological challenges. This study aims to qualitatively synthesise the methods for incorporating equity in clinical practice guidelines (CPGs). Setting Content analysis of methodological publications. Eligibility criteria for selecting studies Methodological publications were included if they provided checklists/frameworks on when, how and to what extent equity should be incorporated in CPGs. Data sources We electronically searched MEDLINE, retrieved references, and browsed guideline development organisation websites from inception to January 2013. After study selection by two authors, general characteristics and checklists items/framework components from included studies were extracted. Based on the questions or items from checklists/frameworks (unit of analysis), content analysis was conducted to identify themes and questions/items were grouped into these themes. Primary outcomes The primary outcomes were methodological themes and processes on how to address equity issues in guideline development. Results 8 studies with 10 publications were included from 3405 citations. In total, a list of 87 questions/items was generated from 17 checklists/frameworks. After content analysis, questions were grouped into eight themes (‘scoping questions’, ‘searching relevant evidence’, ‘appraising evidence and recommendations’, ‘formulating recommendations’, ‘monitoring implementation’, ‘providing a flow chart to include equity in CPGs’, and ‘others: reporting of guidelines and comments from stakeholders’ for CPG developers and ‘assessing the quality of CPGs’ for CPG users). Four included studies covered more than five of these themes. We also summarised the process of guideline development based on the themes mentioned above. Conclusions For disadvantaged population-specific CPGs, eight important methodological issues identified in this review should be considered when including equity in CPGs under the guidance of a scientific guideline development manual.

Some of the practical questions that arise when one decides to use Loran-C in a time reference system are explored. An extensive effort is made to provide basic, practical information on establishing and operating a reference station. Four areas were covered: (1) the design, configuration and operational concepts which should be considered prior to establishing and operating a reference station using Loran-C, (2) the options and tradeoffs available regarding capabilities, cost, size, versatility, ease of operation, etc., that are available to the designer, (3) what measurements are made, how they are made and what they mean, and (4) the experience the U.S. Naval Observatory Time Service Division has had in the design and operation of such stations.

Science at the supermarket: multiplication, personalization and consumption of science in everyday life.

Tateo, Luca

2014-06-01

Which is the kind science's psychological guidance upon everyday life? I will try to discuss some issues about the role that techno-scientific knowledge plays in sense-making and decision making about practical questions of life. This relation of both love and hate, antagonism and connivance is inscribable in a wider debate between a trend of science to intervene in fields that are traditionally prerogative of political, religious or ethical choices, and, on the other side, the position of those who aim at stemming "technocracy" and governing these processes. I argue that multiplication, personalization and consumption are the characteristics of the relationship between science, technology and society in the age of "multiculturalism" and "multi-scientism". This makes more difficult but intriguing the study and understanding of the processes through which scientific knowledge is socialized. Science topics, like biotech, climate change, etc. are today an unavoidable reference frame. It is not possible to not know them and to attach them to the most disparate questions. Like in the case of Moscovici's "Freud for all seasons", the fact itself that the members of a group or a society believe in science as a reference point for others, roots its social representation and the belief that it can solve everyday life problems.

The intended meaning behind responses to standard questions posed in large-scale health surveys are not always well understood. Systematic follow-up studies, particularly those which pose a few repeated questions followed by open-ended discussions, are well positioned to gauge stability and consistency of data and to shed light on the intended meaning behind survey responses. Such follow-up studies require extensive coordination and face challenges in protecting respondent confidentiality during the process of recontacting and reinterviewing participants. We describe practical field strategies for undertaking a mixed methods follow-up study during a large-scale health survey. The study was designed as a mixed methods follow-up study embedded within the 2014 Ghana Demographic and Health Survey (GDHS). The study was implemented in 13 clusters. Android tablets were used to import reference data from the parent survey and to administer the questionnaire, which asked a mixture of closed- and open-ended questions on reproductive intentions, decision-making, and family planning. Despite a number of obstacles related to recontacting respondents and concern about respondent fatigue, over 92 percent of the selected sub-sample were successfully recontacted and reinterviewed; all consented to audio recording. A confidential linkage between GDHS data, follow-up tablet data, and audio transcripts was successfully created for the purpose of analysis. We summarize the challenges in follow-up study design, including ethical considerations, sample size, auditing, filtering, successful use of tablets, and share lessons learned for future such follow-up surveys.

Using climate models to estimate the quality of global observational data sets.

Observational estimates of the climate system are essential to monitoring and understanding ongoing climate change and to assessing the quality of climate models used to produce near- and long-term climate information. This study poses the dual and unconventional question: Can climate models be used to assess the quality of observational references? We show that this question not only rests on solid theoretical grounds but also offers insightful applications in practice. By comparing four observational products of sea surface temperature with a large multimodel climate forecast ensemble, we find compelling evidence that models systematically score better against the most recent, advanced, but also most independent product. These results call for generalized procedures of model-observation comparison and provide guidance for a more objective observational data set selection.

Increasing life expectancy of water resources literature

Heistermann, M.; Francke, T.; Georgi, C.; Bronstert, A.

2014-06-01

In a study from 2008, Larivière and colleagues showed, for the field of natural sciences and engineering, that the median age of cited references is increasing over time. This result was considered counterintuitive: with the advent of electronic search engines, online journal issues and open access publications, one could have expected that cited literature is becoming younger. That study has motivated us to take a closer look at the changes in the age distribution of references that have been cited in water resources journals since 1965. Not only could we confirm the findings of Larivière and colleagues. We were also able to show that the aging is mainly happening in the oldest 10-25% of an average reference list. This is consistent with our analysis of top-cited papers in the field of water resources. Rankings based on total citations since 1965 consistently show the dominance of old literature, including text books and research papers in equal shares. For most top-cited old-timers, citations are still growing exponentially. There is strong evidence that most citations are attracted by publications that introduced methods which meanwhile belong to the standard toolset of researchers and practitioners in the field of water resources. Although we think that this trend should not be overinterpreted as a sign of stagnancy, there might be cause for concern regarding how authors select their references. We question the increasing citation of textbook knowledge as it holds the risk that reference lists become overcrowded, and that the readability of papers deteriorates.

Medial PFC Damage Abolishes the Self-reference Effect

Philippi, Carissa L.; Duff, Melissa C.; Denburg, Natalie L.; Tranel, Daniel; Rudrauf, David

2012-01-01

Functional neuroimaging studies suggest that the medial PFC (mPFC) is a key component of a large-scale neural system supporting a variety of self-related processes. However, it remains unknown whether the mPFC is critical for such processes. In this study, we used a human lesion approach to examine this question. We administered a standard trait judgment paradigm [Kelley, W. M., Macrae, C. N., Wyland, C. L., Caglar, S., Inati, S., & Heatherton, T. F. Finding the self? An event-related fMRI study. Journal of Cognitive Neuroscience, 14, 785–794, 2002] to patients with focal brain damage to the mPFC. The self-reference effect (SRE), a memory advantage conferred by self-related processing, served as a measure of intact self-processing ability. We found that damage to the mPFC abolished the SRE. The results demonstrate that the mPFC is necessary for the SRE and suggest that this structure is important for self-referential processing and the neural representation of self. PMID:21942762

Unstable Expression of Commonly Used Reference Genes in Rat Pancreatic Islets Early after Isolation Affects Results of Gene Expression Studies.

The use of RT-qPCR provides a powerful tool for gene expression studies; however, the proper interpretation of the obtained data is crucially dependent on accurate normalization based on stable reference genes. Recently, strong evidence has been shown indicating that the expression of many commonly used reference genes may vary significantly due to diverse experimental conditions. The isolation of pancreatic islets is a complicated procedure which creates severe mechanical and metabolic stress leading possibly to cellular damage and alteration of gene expression. Despite of this, freshly isolated islets frequently serve as a control in various gene expression and intervention studies. The aim of our study was to determine expression of 16 candidate reference genes and one gene of interest (F3) in isolated rat pancreatic islets during short-term cultivation in order to find a suitable endogenous control for gene expression studies. We compared the expression stability of the most commonly used reference genes and evaluated the reliability of relative and absolute quantification using RT-qPCR during 0-120 hrs after isolation. In freshly isolated islets, the expression of all tested genes was markedly depressed and it increased several times throughout the first 48 hrs of cultivation. We observed significant variability among samples at 0 and 24 hrs but substantial stabilization from 48 hrs onwards. During the first 48 hrs, relative quantification failed to reflect the real changes in respective mRNA concentrations while in the interval 48-120 hrs, the relative expression generally paralleled the results determined by absolute quantification. Thus, our data call into question the suitability of relative quantification for gene expression analysis in pancreatic islets during the first 48 hrs of cultivation, as the results may be significantly affected by unstable expression of reference genes. However, this method could provide reliable information from 48 hrs onwards.

The purpose of this study is to assess the usefulness of five full-text drug databases as evaluated by medical librarians, pharmacy faculty, and pharmacy students at an academic health center. Study findings and recommendations are offered as guidance to librarians responsible for purchasing decisions. Four pharmacy students, four pharmacy faculty members, and four medical librarians answered ten drug information questions using the databases AHFS Drug Information (STAT!Ref); DRUGDEX (Micromedex); eFacts (Drug Facts and Comparisons); Lexi-Drugs Online (Lexi-Comp); and the PDR Electronic Library (Micromedex). Participants noted whether each database contained answers to the questions and evaluated each database on ease of navigation, screen readability, overall satisfaction, and product recommendation. While each study group found that DRUGDEX provided the most direct answers to the ten questions, faculty members gave Lexi-Drugs the highest overall rating. Students favored eFacts. The faculty and students found the PDR least useful. Librarians ranked DRUGDEX the highest and AHFS the lowest. The comments of pharmacy faculty and students show that these groups preferred concise, easy-to-use sources; librarians focused on the comprehensiveness, layout, and supporting references of the databases. This study demonstrates the importance of consulting with primary clientele before purchasing databases. Although there are many online drug databases to consider, present findings offer strong support for eFacts, Lexi-Drugs, and DRUGDEX.

In today's fast-paced environment, traditional medical reference services alone are not adequate to meet users' information needs. Efforts to find new ways to provide comprehensive service to users, where and when needed, have often included the use of new and developing technologies. This paper describes the experience of an academic health science library in developing and providing an online, real-time reference service. Issues discussed include selecting software, training librarians, staffing the service, and considering the future of the service. Use statistics, question type analysis, and feedback from users of the service and librarians who staff the service, are also presented.

The self-study program has been a great success. Staff seized the opportunity for "hands-on," nonthreatening learning. The fear of asking questions and appearing less knowledgeable than peers in a group setting is removed, and new employees are grateful for the rapid accessibility of concise reference material. Everyone enjoys the freedom of fitting the in-service program into a routine day, rather than trying to adapt to a set time. Last, but not least, management reaps to the benefit of a program that satisfies the expectations of regulatory agencies and is virtually cost-free.

Clinical studies of fiber posts: a literature review.

2008-01-01

This literature review aimed to find answers to relevant questions regarding the clinical outcome of endontically treated teeth restored with fiber posts. All clinical studies published since 1990 in journals indexed in MEDLINE were retrieved by searching PubMed with the query terms "fiber posts and clinical studies." The reference list of the collected articles was also screened for further relevant citations. The strength of the evidence provided by the reviewed papers was assessed according to the criteria of evidence-based dentistry. Five randomized controlled trials (RCTs) on fiber posts have been published in peer-reviewed journals. A meta-analysis is not applicable to these studies since they do not address the same specific clinical question. Retrospective and prospective trials without controls are also available. Two RCTs indicate that fiber-reinforced composite posts outperform metal posts in the restoration of endontically treated teeth. However, this evidence cannot be considered as conclusive. Longer-term RCTs would be desirable. The placement of a fiber-reinforced composite post protects against failure, especially under conditions of extensive coronal destruction. The most common type of failure with fiber-reinforced composite posts is debonding.

Previous studies linked heavy computer use to disturbed sleep. This study investigates the association between computer use during work and leisure and sleep problems in working adults. From the 2010 round of the Danish Work Environment Cohort Study, currently employed wage earners on daytime schedule (N = 7883) replied to the Bergen insomnia scale and questions on weekly duration of computer use. Results showed that sleep problems for three or more days per week (average of six questions) were experienced by 14.9% of the respondents. Logistic regression analyses, controlled for gender, age, physical and psychosocial work factors, lifestyle, chronic disease and mental health showed that computer use during leisure for 30 or more hours per week (reference 0-10 hours per week) was associated with increased odds of sleep problems (OR 1.83 [95% CI 1.06-3.17]). Computer use during work and shorter duration of computer use during leisure were not associated with sleep problems. In conclusion, excessive computer use during leisure - but not work - is associated with sleep problems in adults working on daytime schedule.

A framework for studying emotions across species.

PubMed

Anderson, David J; Adolphs, Ralph

2014-03-27

Since the 19th century, there has been disagreement over the fundamental question of whether "emotions" are cause or consequence of their associated behaviors. This question of causation is most directly addressable in genetically tractable model organisms, including invertebrates such as Drosophila. Yet there is ongoing debate about whether such species even have "emotions," as emotions are typically defined with reference to human behavior and neuroanatomy. Here, we argue that emotional behaviors are a class of behaviors that express internal emotion states. These emotion states exhibit certain general functional and adaptive properties that apply across any specific human emotions like fear or anger, as well as across phylogeny. These general properties, which can be thought of as "emotion primitives," can be modeled and studied in evolutionarily distant model organisms, allowing functional dissection of their mechanistic bases and tests of their causal relationships to behavior. More generally, our approach not only aims at better integration of such studies in model organisms with studies of emotion in humans, but also suggests a revision of how emotion should be operationalized within psychology and psychiatry.

To evaluate the use of mobile technology to facilitate resident learning, assess clinical knowledge, and guide curricular development in a busy clinical environment. This was a cross-sectional study conducted in a large (N=48) urban obstetrics and gynecology residency program. Question sets were created in the following areas: office gynecology, general obstetrics, gynecologic surgery and urogynecology, maternal-fetal medicine and ultrasonography, reproductive endocrinology and pediatric gynecology, and gynecologic oncology. Using an educational mobile application (app), questions were sent monthly to resident smartphones with immediate feedback on answer accuracy along with answer explanation and references. Outcomes included app use, which was determined by how quickly participants answered questions (very active-active indicates questions answered within 7 days) and proficiency (mean percentage correct) calculated for individuals, resident class level, and by content area. All 48 residents participated and 77.4% were very active or active app users. On average, participants answered correctly 61.0% on the first attempt and improved to 78.3% on repeat attempt (P<.001). Proficiency was lowest for gynecologic surgery and highest for general obstetrics. A mobile app to support e-learning was successfully implemented in our program; its use was associated with knowledge retention and identification of low-proficiency topics to guide curriculum development.

To investigate the influence of various factors on the ability of primary school children (aged 6-9 years) to refer an event that occurred during their life. The factors analyzed were: the time since the event occurred; the role the child had in the event; the type of questions asked to elicit the account. The results of this research indicate that 52.4% of 6-year old children are able to describe the main elements of the event if they are allowed to give a free account. Asking direct questions does not improve the quality of the narrative. By contrast, in 9-year-old children the quantity of data collected is improved if direct questions are asked. A role as a participant in the event improves the quality of the child's evidence but only in the group of children aged 9, whereas in younger children the difference is not significant. At the age of 9, the child's resistance to leading questions is already quite good (40.7%), whereas children of 6 are much more suggestible. The Authors conclude this work by making some reflections on the possible use of these findings in Law Courts, and on the need for a highly specific training of experts involved in the task of collecting evidence from young children.

TU-D-201-03: Results of a Survey On the Implementation of the TG-51 Protocol and Associated Addendum On Reference Dosimetry of External Beams

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kim, G; Muir, B; Culberson, W

Purpose: The working group on the review and extension of the TG-51 protocol (WGTG51) collected data from American Association of Physicists in Medicine (AAPM) members with respect to their current TG-51 and associated addendum usage in the interest of considering future protocol addenda and guidance on reference dosimetry best practices. This study reports an overview of this survey on dosimetry of external beams. Methods: Fourteen survey questions were developed by WGTG51 and released in November 2015. The questions collected information on reference dosimetry, beam quality specification, and ancillary calibration equipment. Results: Of the 190 submissions completed worldwide (U.S. 70%), 83%more » were AAPM members. Of the respondents, 33.5% implemented the TG-51 addendum, with the maximum calibration difference for any photon beam, with respect to the original TG-51 protocol, being <1% for 97.4% of responses. One major finding is that 81.8% of respondents used the same cylindrical ionization chamber for photon and electron dosimetry, implying that many clinics are foregoing the use of parallel-plate chambers. Other evidence suggests equivalent dosimetric results can be obtained with both cylindrical and parallel-plate chambers in electron beams. This, combined with users comfort with cylindrical chambers for electrons will likely impact recommendations put forward in an upcoming electron beam addendum to the TG-51 protocol. Data collected on ancillary equipment showed 58.2% (45.0%) of the thermometers (barometers) in use for beam calibration had NIST traceable calibration certificates, but 48.4% (42.7%) were never recalibrated. Conclusion: This survey provides a snapshot of TG-51 external beam reference dosimetry practice in radiotherapy centers. Findings demonstrate the rapid take-up of the TG-51 photon beam addendum and raise issues for the WGTG51 to focus on going forward, including guidelines on ancillary equipment and the choice of chamber for electron beam dosimetry.« less

Productive whole-class discussions: A qualitative analysis of peer leader behaviors in general chemistry

NASA Astrophysics Data System (ADS)

Eckart, Teresa Mcclain

The intention of this research was to describe behaviors and characteristics of General Chemistry I peer leaders using a pedagogical reform method referred to as Peer-led Guided Inquiry (PLGI), and to discuss the ways in which these peer leaders created productive whole-class discussions. This reform technique engaged students to work on guided inquiry activities while working cooperatively in small groups, led by undergraduate peer leaders. These sessions were video recorded and transcribed. The data was evaluated using grounded theory methods of analysis. This study examined the dialog between students and peer leaders, paying specific attention to question types and observed patterns of interactions. The research took shape by examining the kinds of questions asked by peer leaders and the purposes these questions served. In addition to looking at questions, different kinds of behaviors displayed by peer leaders during their small group sessions were also observed. A close examination of peer leader questions and behaviors aided in developing an answer to the overall research question regarding what factors are associated with productive whole-class discussions. Five major categories of peer leader behaviors evolved from the data and provided a means to compare and contrast productive whole-class discussions. While no category single-handedly determined if a discussion was good or bad, there was a tendency for peer leaders who exhibited positive traits in at least three of the following categories to have consistently better whole-class discussions: Procedural Practices, Supervisory Qualities, Questioning Techniques, Feedback/Responses, and Interpersonal Skills. Furthermore, each of the major categories is tied directly to Interpersonal, Communication, and Leadership skills and their interactions with each other. This study also addressed applications that each of these categories has on instructional practices and their need in peer leader training. In addition, a scale was developed for rating the relative effectiveness of whole-class discussions in terms of student participation. This study provides a tool for measuring productive whole-class discussions, as well as practical applications for peer leader (or teacher) training.

Language in context: Characterizing the comprehension of referential expressions with MEG.

PubMed

Brodbeck, Christian; Pylkkänen, Liina

2017-02-15

A critical component of comprehending language in context is identifying the entities that individual linguistic expressions refer to. While previous research has shown that language comprehenders resolve reference quickly and incrementally, little is currently known about the neural basis of successful reference resolution. Using source localized MEG, we provide evidence across 3 experiments and 2 languages that successful reference resolution in simple visual displays is associated with increased activation in the medial parietal lobe. In each trial, participants saw a simple visual display containing three objects which constituted the referential domain. Target referential expressions were embedded in questions about the displays. By varying the displays, we manipulated referential status while keeping the linguistic expressions constant. Follow-up experiments addressed potential interactions of reference resolution with linguistic predictiveness and pragmatic plausibility. Notably, we replicated the effect in Arabic, a language that differs in a structurally informative way from English while keeping referential aspects parallel to our two English studies. Distributed minimum norm estimates of MEG data consistently indicated that reference resolution is associated with increased activity in the medial parietal lobe. With one exception, the timing of the onset of the medial parietal response fell into a mid-latency time-window at 350-500ms after the onset of the resolving word. Through concurrent EEG recordings on a subset of subjects we also describe the EEG topography of the effect of reference resolution, which makes the result available for comparison with a larger existing literature. Our results extend previous reports that medial parietal lobe is involved in referential language processing, indicating that it is relevant for reference resolution to individual referents, and suggests avenues for future research.

Veterans are at heightened risk for perpetrating intimate partner violence (IPV), yet there is limited evidence to inform practice and policy for the detection of IPV perpetration. The present study evaluated the accuracy and acceptability of a potential IPV perpetration screening tool for use with women veterans. A national sample of women veterans completed a 2016 web-based survey that included a modified 5-item Extended-Hurt/Insult/Threaten/Scream (Modified E-HITS) and the Revised Conflict Tactics Scales (CTS-2). Items also assessed women's perceptions of the acceptability and appropriateness of the modified E-HITS questions for use in healthcare settings. Accuracy statistics, including sensitivity and specificity, were calculated using the CTS-2 as the reference standard. Primary measures included the Modified E-HITS (index test), CTS-2 (reference standard), and items assessing acceptability. This study included 187 women, of whom 31 women veterans (16.6%) reported past-6-month IPV perpetration on the CTS-2. The Modified E-HITS demonstrated good overall accuracy (area under the curve, 0.86; 95% confidence interval, 0.78-0.94). In addition, the majority of women perceived the questions to be acceptable and appropriate. Findings demonstrate that the Modified E-HITS is promising as a low-burden tool for detecting of IPV perpetration among women veterans. This tool may help the Veterans Health Administration and other health care providers detect IPV perpetration and offer appropriate referrals for comprehensive assessment and services.

Genome Diversity and Evolution in the Budding Yeasts (Saccharomycotina)

Dujon, Bernard A.; Louis, Edward J.

2017-01-01

Considerable progress in our understanding of yeast genomes and their evolution has been made over the last decade with the sequencing, analysis, and comparisons of numerous species, strains, or isolates of diverse origins. The role played by yeasts in natural environments as well as in artificial manufactures, combined with the importance of some species as model experimental systems sustained this effort. At the same time, their enormous evolutionary diversity (there are yeast species in every subphylum of Dikarya) sparked curiosity but necessitated further efforts to obtain appropriate reference genomes. Today, yeast genomes have been very informative about basic mechanisms of evolution, speciation, hybridization, domestication, as well as about the molecular machineries underlying them. They are also irreplaceable to investigate in detail the complex relationship between genotypes and phenotypes with both theoretical and practical implications. This review examines these questions at two distinct levels offered by the broad evolutionary range of yeasts: inside the best-studied Saccharomyces species complex, and across the entire and diversified subphylum of Saccharomycotina. While obviously revealing evolutionary histories at different scales, data converge to a remarkably coherent picture in which one can estimate the relative importance of intrinsic genome dynamics, including gene birth and loss, vs. horizontal genetic accidents in the making of populations. The facility with which novel yeast genomes can now be studied, combined with the already numerous available reference genomes, offer privileged perspectives to further examine these fundamental biological questions using yeasts both as eukaryotic models and as fungi of practical importance.

Drott, Jenny; Vilhelmsson, Maria; Kjellgren, Karin; Berterö, Carina

2016-06-09

In cancer care, mobile phone-based systems are becoming more widely used in the assessment, monitoring, and management of side effects. To explore the experiences of patients with colorectal cancer on using a mobile phone-based system for reporting neurotoxic side effects. Eleven patients were interviewed (ages 44-68 years). A semistructured interview guide was used to perform telephone interviews. The interviews were transcribed verbatim and analyzed with qualitative content analysis. The patients' experiences of using a mobile phone-based system were identified and constructed as: "being involved," "pacing oneself," and "managing the questions." "Being involved" refers to their individual feelings. Patients were participating in their own care by being observant of the side effects they were experiencing. They were aware that the answers they gave were monitored in real time and taken into account by health care professionals when planning further treatment. "Pacing oneself" describes how the patients can have an impact on the time and place they choose to answer the questions. Answering the questionnaire was easy, and despite the substantial number of questions, it was quickly completed. "Managing the questions" pointed out that the patients needed to be observant because of the construction of the questions. They could not routinely answer all the questions. Patients understood that side effects can vary during the cycles of treatment and need to be assessed repeatedly during treatment. This mobile phone-based system reinforced the patients' feeling of involvement in their own care. The patients were comfortable with the technology and appreciated that the system was not time consuming.

For the purpose of exploring the existence of problem areas that may give rise to the question whether there is a tendency to (illegitimately) trespass across boundaries between medical sociology and epidemiology, important convergences and divergences between both disciplines are described. To assemble arguments for the legitimacy of fields of study we trace comparatively the history of both disciplines, definitions of their fields under study and aims of study, as well as characteristic concepts and constructs. Current research themes are taken from international journals; divergent interests are briefly described and potential 'trespassing' of boundaries is discussed, referring to themes showing convergences of interest.

Grid fin is an aerodynamic control surface that usually used on missiles and rockets. In the recent several years many researches have conducted to develop a more efficient grid fins. There are many possibilities of geometric combination could be done to improve aerodynamics characteristic of a grid fin. This paper will only discuss about the aerodynamics characteristics of grid fins compared by another grid fins with different swept angle. The methodology that used to compare the aerodynamics is Computational Fluid Dynamics (CFD). The result of this paper might be used for future studies to answer our former question or as a reference for related studies.

Rodríguez-Blanes, Gloria M; Vives-Cases, Carmen; Miralles-Bueno, Juan José; San Sebastián, Miguel; Goicolea, Isabel

Intimate partner violence (IPV) against women is a significant public health and human rights problem. Primary care professionals play a key role in detecting and addressing this issue. The aim of this study is to determine the frequency of IPV and its associated factors in primary care by means of a screening questionnaire and to describe the main actions taken in identified cases. Cross-sectional study in 15 health centres in four autonomous regions of Spain with a total of 265 health professionals. The information was collected through the self-administered PREMIS questionnaire (Physician Readiness to Manage Intimate Partner Violence Survey), which includes variables concerning screening questions, sociodemographic factors, level of training/knowledge about IPV, perceptions and actions. A descriptive and analytical study was conducted. 67.2% of participants said they ask about IPV during consultations. The most frequent actions were: referring patients to other departments, individual counselling and information delivery. ≥21hours of training, an advanced training level, knowledge of policies and programmes and the implementation of an appropriate protocol and reference resources were all factors that increased the likelihood of investigating IPV. The asking of questions increases in line with professionals' perceived level of training in IPV and the provision of a case management protocol. Two thirds of health professional respondents said they inquire about IPV. Given the influence of training in IPV and awareness of the resources to address the issue, it is essential to continue investing in the IPV training of healthcare personnel. Copyright © 2017 SESPAS.

This article presents the partial results of a multicenter, cross-temporal study, which was performed using multiple methods, and involved seven Latin-American countries and Canada. The results presented refer to the city center of Rio de Janeiro (n=108). The central question of the study was: 'How do illicit drug users' relatives and acquaintances describe protective and risk factors, prevention initiatives, treatment services, laws and policies regarding illicit drugs?' The quantitative data was collected using an instrument containing closed questions. In total, 108 young adults (18 years of age or older) were interviewed, who stated being affected by the drug although they were not users. For 104 interviewees (96%), negligence is the family dynamics that causes the greatest exposure to drugs, and 106 (98%) consider that parent support is what offers the greatest protection. Policies, the police and the criminal system have neither reduced drug use nor do they protect users.

The Psychometric Properties of Classroom Response System Data: A Case Study

NASA Astrophysics Data System (ADS)

Kortemeyer, Gerd

2016-08-01

Classroom response systems (often referred to as "clickers") have slowly gained adoption over the recent decade; however, critics frequently doubt their pedagogical value starting with the validity of the gathered responses: There is concern that students simply "click" random answers. This case study looks at different measures of response reliability, starting from a global look at correlations between formative clicker responses and summative examination performance to how clicker questions are used in context. It was found that clicker performance is a moderate indicator of course performance as a whole, and that while the psychometric properties of clicker items are more erratic than those of examination data, they still have acceptable internal consistency and include items with high discrimination. It was also found that clicker responses and item properties do provide highly meaningful feedback within a lecture context, i.e., when their position and function within lecture sessions are taken into consideration. Within this framework, conceptual questions provide measurably more meaningful feedback than items that require calculations.

Surprisingly, people incorporate errors into their knowledge bases even when they have the correct knowledge stored in memory (e.g., Fazio, Barber, Rajaram, Ornstein, & Marsh, 2013). We examined whether heightening the accessibility of correct knowledge would protect people from later reproducing misleading information that they encountered in fictional stories. In Experiment 1, participants studied a series of target general knowledge questions and their correct answers either a few minutes (high accessibility of knowledge) or 1 week (low accessibility of knowledge) before exposure to misleading story references. In Experiments 2a and 2b, participants instead retrieved the answers to the target general knowledge questions either a few minutes or 1 week before the rest of the experiment. Reading the relevant knowledge directly before the story-reading phase protected against reproduction of the misleading story answers on a later general knowledge test, but retrieving that same correct information did not. Retrieving stored knowledge from memory might actually enhance the encoding of relevant misinformation.

Guidelines and Capabilities for Designing Human Missions

NASA Technical Reports Server (NTRS)

2002-01-01

The human element is likely the most complex and difficult one of mission design; it significantly influences every aspect of mission planning, from the basic parameters like duration to the more complex tradeoffs between mass, volume, power, risk, and cost. For engineers who rely on precise specifications in data books and other such technical references, dealing with the uncertainty and the variability of designing for human beings can be frustrating. When designing for the human element, questions arise more often than definitive answers. Nonetheless, we do not doubt that the most captivating discoveries in future space missions will necessitate human explorers. These guidelines and capabilities are meant to identify the points of intersection between humans and mission considerations such as architecture, vehicle design, technologies, operations, and science requirements. We seek to provide clear, top-level guidelines for human-related exploration studies and technology research that address common questions and requirements. As a result, we hope that ongoing mission trade studies consider common, standard, and practical criteria for human interfaces.

2004-01-01

The aim of the present study was to test the hypothesis that unmarried (single) men have more sleep-disordered breathing symptoms due to a higher prevalence of obesity and a less healthy lifestyle than men living with a partner. Men (499) aged 23-66 years completed a structured questionnaire, had standard anthropometric measurements and a simple, noninvasive nose-throat examination. Of the 499,496 subjects answered the question concerning their marital status; 86% of them were married or lived with a partner (reference group) and the other 14% had never been married, divorced, or widowed ("single" group, considered at risk). Single subjects were younger, included slightly more smokers (30 vs. 23%) and more subjects with a history of chronic bronchitis, and less frequently had a large soft palate. The prevalence of sleep-disordered symptoms was not significantly different between the two groups. However, a study involving a larger number of subjects with information regarding alcoholic consumption may be needed to further evaluate this question.

2017-04-01

Non-cardiac critically ill patients with type II myocardial infarction (MI) have a high risk of mortality. There are no evidence-based interventions to mitigate this risk. We systematically reviewed the literature regarding the use of medications known to reduce mortality in patients with cardiac troponin (cTn) elevation due to type I MI (β blockers, statin, and aspirin) in studies of critically ill patients without Type I MI. All PubMed publications between 1976-2/19/16 were reviewed. Search terms included: β blocker or aspirin or statin and intensive care unit (ICU) or critically ill or sepsis; 497 primary references were obtained. Inclusion criteria were as follows: (1) study population consisted of critically ill patients in the ICU with non-cardiovascular illnesses, (2) mortality end point, (3) severity of illness (or injury) was measured, and (4) the antiplatelet agent was primarily aspirin. Retrospective investigations, prospective observational studies, meta-analysis, systematic review, and randomized controlled trials were included; case reports were excluded. 25 primary references were obtained. The data were extracted and tabulated using data collection headings as follows: article title, first author/year/reference number, study type/design, population studied, outcome and intervention, and study question addressed. Evidence was not graded as the majority of studies were non-randomized (low-to-moderate quality). 11 studies were found through bibliography reviews for a total of 36 references. In conclusion, β blockers, statins, and aspirin may play a role in reducing mortality in non-cardiac critically ill patients. Benefit appears to be related to severity of illness, for which cTn may be a marker. Copyright © 2017 American Federation for Medical Research.

Unique Assessment of Hand Surgery Knowledge by Specialty.

2016-03-01

Orthopedic and plastic surgery residents receive unique training yet often compete for similar hand surgery fellowships. This study compared didactic hand surgery training during orthopedic and plastic surgery residency. The Plastic Surgery In-Service Training Exam and Orthopaedic In-Training Examination were analyzed for hand content for the years 2009 to 2013. Topics were categorized with the content outline for the Surgery of the Hand Examination. Differences were elucidated by means of Fisher's exact test. Relative to the Orthopaedic In-Training Examination, the Plastic Surgery In-Service Training Exam had greater hand representation (20.3 percent versus 8.1 percent; p < 0.001) with more annual hand questions (40 ± 3 versus 24 ± 2; p < 0.001). The Plastic Surgery Exam questions had more words, were less often level I-recall type, and were less often image-based. The questions focused more on finger and hand/palm anatomy, whereas the Orthopaedic examination was more wrist-focused. The Plastic Surgery Exam emphasized wound management and muscle/tendon injuries, but underemphasized fractures/dislocations. References differed, but Journal of Hand Surgery (American Volume) and Green's Operative Hand Surgery were common on both examinations. The Plastic Surgery Exam had a greater publication lag for journal references (10.7 ± 0.5 years versus 9.0 ± 0.6; p = 0.035). Differences in didactic hand surgery training are elucidated for plastic surgery and orthopedic residents. Deficiencies in the Plastic Surgery In-Service Training Exam hand curriculum relative to the Orthopaedic In-Training Examination may underprepare plastic surgeons for the Surgery of the Hand Examination. These data may assist future modifications to hand surgery training in the United States.

Integrated Knowledge Translation: illustrated with outcome research in mental health.

2015-01-01

Through this article the authors present a case summary of the early phases of research conducted with an Integrated Knowledge Translation (iKT) approach utilizing four factors: research question, research approach, feasibility, and outcome. iKT refers to an approach for conducting research in which community partners, referred to as knowledge users, are engaged in the entire research process. In this collaborative approach, knowledge users and researchers jointly devise the entire research agenda beginning with the development of the research question(s), determination of a feasible research design and feasible methods, interpretation of the results, dissemination of the findings, and the translation of knowledge into practice or policy decisions. Engaging clinical or community partners in the research enterprise can enhance the utility of the research results and facilitate its uptake. This collaboration can be a complex arrangement and flexibility may be required to accommodate the various configurations that the collaboration can take. For example, the research question can be jointly determined and refined; however, one person must take the responsibility for orchestrating the project, including preparing the proposal and application to the Research Ethics Board. This collaborative effort also requires the simultaneous navigation of barriers and facilitators to the research enterprise. Navigating these elements becomes part of the conduct of research with the potential for rewarding results, including an enriched work experience for clinical partners and investigators. One practice implication is that iKT may be considered of great utility to service providers due to its field friendly nature.

The study analysed public debates on the association of milk fats, vegetable oils and cardiovascular diseases (CVDs) between 1978 and 2013 in Finland, a country with a decades-long history of public health initiatives targeting fat consumption. The main agendas, conflicts and participants were analysed. The data were collected from the newspaper Helsingin Sanomat and consisted of 52 threads and 250 texts. We identified four themes around which there were repeated, often overlapping conflicts: the health risks of saturated fats, expertise of the risks of fat consumption, the adequate evidence of the risks of fat consumption, and framing the fat question. During the research period, the main arguments of the effects of consumption of fats have remained the same. References to epidemiological and intervention studies and framing of the fat question as a public health issue, have been ongoing, as has the definition of what constitutes genuine expertise. Yet, we also found discontinuities. In the early 2000s new emphases began to emerge: personal experiences were increasingly presented as evidence of the effects of dietary choices on human health, and the question of fat consumption was framed either as one of enjoyment or of a consumers' right to choose rather than only being a public health question. Moreover, new professional groups such as chefs and creative professionals now joined the discussion. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Chemical regulators of plant hormones and their applications in basic research and agriculture.

Jiang, Kai; Asami, Tadao

2018-04-20

Plant hormones are small molecules that play versatile roles in regulating plant growth, development, and responses to the environment. Classic methodologies, including genetics, analytic chemistry, biochemistry, and molecular biology, have contributed to the progress in plant hormone studies. In addition, chemical regulators of plant hormone functions have been important in such studies. Today, synthetic chemicals, including plant growth regulators, are used to study and manipulate biological systems, collectively referred to as chemical biology. Here, we summarize the available chemical regulators and their contributions to plant hormone studies. We also pose questions that remain to be addressed in plant hormone studies and that might be solved with the help of chemical regulators.

The last study to establish centiles of main anthropometric measurements in Kinshasa was conducted over 60 years ago, which questions its current adequacy to describe or monitor growth in this population. To assess the nutritional status of school-aged children and adolescents and to estimate centile curves of height, weight and body mass index (BMI). A representative sample of 7541 school-aged children and adolescents (48% boys) aged 6-18 years was measured between 2010-2013. Smooth centiles of height, weight and BMI-for-age were estimated with the LMS method and compared with the WHO 2007 reference. Nutritional status was assessed by comparing measurements of height and BMI against the appropriate WHO cut-offs. Compared to the WHO reference, percentiles of height and BMI were generally lower. This difference was larger in boys than in girls and increased as they approached adolescence. The prevalence of short stature (< -2 SD) and thinness (< -2 SD) was higher in boys (9.8% and 12%) than in girls (3.4% and 6.1%), but the prevalence of overweight (> 1 SD) was higher in girls (8.6%) than in boys (4.5%). Children from Kinshasa fall below WHO centile references. This study established up-to-date centile curves for height, weight and BMI by age in children and adolescents. These reference curves describe the current status of these anthropometric markers and can be used as a basis for comparison in future studies.

The aim of this study was to analyse the efficiency of muscular activity in the trunk stabilisation of professional volleyball players compared to a group of amateur hobby players. The results were compared amongst the groups as well as with a reference group consisting of asymptomatic individuals. The question to be answered was whether or not professional volleyball players possess a characteristic strength profile in their trunk musculature and if differences exist with regard to the individuals' competitive playing level. In this comparative study 12 professional volleyball players (German Bundesliga) and 18 non-professional volleyball players were analysed with regard to their isometric strength profile in all three planes. The reference group was provided by the Proxomed company, which had previously analysed healthy untrained individuals (n = 1045) of various age groups. A sports-specific profile for the musculature of volleyball players revealed a significant reduction in the flexion and rotation strength as well as a well-developed lateral flexion strength (highly significant when compared to the reference group). With reference to the level played, better strength values in flexion and lateral flexion were found among the professional athletes. Professional volleyball players present with a characteristic trunk musculature strength profile. A detailed analysis of the muscle strength of the spine as part of a sports medicine work-up could prove helpful in preventing injuries and overuse problems in professional and hobby volleyball players.

Clinical reasoning is central to any health profession but its development among learners is difficult to assess. Over the last few decades, the script concordance test (SCT) has been developed to solve this dilemma and has been used in many health professions; however, no study has been published on the use of the script concordance test in optometry. The purpose of this study was to develop and validate a script concordance test for the field of optometry. A 101-question script concordance test (27 short clinical scenarios) was developed and administered online to a convenience sample of 23 second-year and 19 fourth-year students of optometry. It was also administered to a reference panel of 12 experienced optometrists to develop the scoring key. An item-total correlation was calculated for each question. Cronbach's alpha coefficient was used to evaluate the script concordance test reliability and a t-test compared the two groups. A final 77-question script concordance test was created by eliminating questions with low item-total correlation. Cronbach's alpha for this optimised 77-question script concordance test was 0.80. A group comparison revealed that the second-year students' scores (n = 23; mean score = 66.4 ± 7.87 per cent) were statistically lower (t = -4.141; p < 0.001) than those of the fourth-year students (n = 19; mean score = 75.5 ± 5.97 per cent). The online script concordance test developed for this study was found to be both reliable and capable of discriminating between second- and fourth-year optometric students. These results demonstrate that the script concordance test may be considered as a new tool in the optometric educators' assessment arsenal. Further studies will be needed to cover additional levels of professional development. © 2016 The Authors. Clinical and Experimental Optometry © 2016 Optometry Australia.

Telephone hotlines designed to address common concerns in the early postpartum could be a useful resource for parents. Our aim was to test the feasibility of using a telephone as an intervention in a randomized controlled trial. We also aimed to test to use of algorithms to address parental concerns through a telephone hotline. Healthy first-time mothers were recruited from postpartum wards of hospitals throughout Lebanon. Participants were given the number of a 24-hour telephone hotline that they could access for the first four months after delivery. Calls were answered by a midwife using algorithms developed by the study team whenever possible. Callers with medical complaints were referred to their physicians. Call patterns and content were recorded and analyzed. Eighty-four of the 353 women enrolled (24%) used the hotline. Sixty percent of the women who used the service called more than once, and all callers reported they were satisfied with the service. The midwife received an average of three calls per day and most calls occurred during the first four weeks postpartum. Our algorithms were used to answer questions in 62.8% of calls and 18.6% of calls required referral to a physician. Of the questions related to mothers, 66% were about breastfeeding. Sixty percent of questions related to the infant were about routine care and 23% were about excessive crying. Utilization of a telephone hotline service for postpartum support is highest in the first four weeks postpartum. Most questions are related to breastfeeding, routine newborn care, and management of a fussy infant. It is feasible to test a telephone hotline as an intervention in a randomized controlled trial. Algorithms can be developed to provide standardized answers to the most common questions.

Background Adult congenital heart disease (ACHD) clinicians are hampered by the paucity of data to inform clinical decision-making. The objective of this study was to identify priorities for clinical research in ACHD. Methods A list of 45 research questions was developed by the Alliance for Adult Research in Congenital Cardiology (AARCC), compiled into a survey, and administered to ACHD providers. Patient input was sought via the Adult Congenital Heart Association at community meetings and online forums. The 25 top questions were sent to ACHD providers worldwide via an online survey. Each question was ranked based on perceived priority and weighted based on time spent in ACHD care. The top 10 topics identified are presented and discussed. Results The final online survey yielded 139 responses. Top priority questions related to tetralogy of Fallot (timing of pulmonary valve replacement and criteria for primary prevention ICDs), patients with systemic right ventricles (determining the optimal echocardiographic techniques for measuring right ventricular function, and indications for tricuspid valve replacement and primary prevention ICDs), and single ventricle/Fontan patients (role of pulmonary vasodilators, optimal anticoagulation, medical therapy for preservation of ventricular function, treatment for protein losing enteropathy). In addition, establishing criteria to refer ACHD patients for cardiac transplantation was deemed a priority. Conclusions The ACHD field is in need of prospective research to address fundamental clinical questions. It is hoped that this methodical consultation process will inform researchers and funding organizations about clinical research topics deemed to be of high priority. PMID:24411207

In addition, establishing criteria to refer ACHD patients for cardiac transplantation was deemed a priority. The ACHD field is in need of prospective research to address fundamental clinical questions. It is hoped that this methodical consultation process will inform researchers and funding organizations about clinical research topics deemed to be of high priority.

Abstract Objective To assess the feasibility of using birth attendants instead of bereaved mothers as perinatal verbal autopsy respondents. Methods Verbal autopsy interviews for early neonatal deaths and stillbirths were conducted separately among mothers (reference standard) and birth attendants in 38 communities in four developing countries. Concordance between maternal and attendant responses was calculated for all questions, for categories of questions and for individual questions. The sensitivity and specificity of individual questions with the birth attendant as respondent were assessed. Findings For early neonatal deaths, concordance across all questions was 94%. Concordance was at least 95% for more than half the questions on maternal medical history, birth attendance and neonate characteristics. Concordance on any given question was never less than 80%. Sensitivity and specificity varied across individual questions, more than 80% of which had a sensitivity of at least 80% and a specificity of at least 90%. For stillbirths, concordance across all questions was 93%. Concordance was 95% or greater more than half the time for questions on birth attendance, site of delivery and stillborn characteristics. Sensitivity and specificity varied across individual questions. Over 60% of the questions had a sensitivity of at least 80% and over 80% of them had a specificity of at least 90%. Overall, the causes of death established through verbal autopsy were similar, regardless of respondent. Conclusion Birth attendants can substitute for bereaved mothers as verbal autopsy respondents. The questions in existing harmonized verbal autopsy questionnaires need further refinement, as their sensitivity and specificity differ widely. PMID:22461715

In our experience, scientists are likely to be newcomers to the scholarship that has arisen from the field of women's studies. This paper will examine one such area of scholarship, feminist pedagogy, and relate it to the teaching and learning of chemistry. More correctly, one should refer to feminist pedagogies, as this scholarship is evolving and is a topic for continual debate. Generally speaking, feminist pedagogies share a number of themes: a focus on women/gender, authority, position, empowerment, voice, and non-neutrality. Each of these themes is described and then applied to the chemistry classroom. Examples include using technology to give students a voice, using same-sex groupings, instituting a class board of directors, examining textbook questions, and asking new or different questions as you teach. Although feminist pedagogy aims to make science classrooms and laboratories more hospitable to women, it can inform our teaching practices and benefit all our students.

Spatial perspective can be directed by various reference frames, as well as by the direction of motion. In the present study, we explored how ambiguity in spatial tasks can be resolved. Participants were presented with virtual reality environments in order to stimulate a spatialreference frame based on motion. They interacted with an ego-moving spatial system in Experiment 1 and an object-moving spatial system in Experiment 2. While interacting with the virtual environment, the participants were presented with either a question representing a motion system different from that of the virtual environment or a nonspatial question relating to physical features of the virtual environment. They then performed the target task assign the label front in an ambiguous spatial task. The findings indicate that the disambiguation of spatial terms can be influenced by embodied experiences, as represented by the virtual environment, as well as by linguistic context.

A precise understanding of the radiological anatomy and biomechanics as well as reliable reference values of the hip are essential. The primary goal of this study was to provide reference values of the neck-shaft angle (NSA) for adult patients based on the analysis of rotation corrected computed tomography (CT) scans of 800 hips. The secondary aim was to compare these measurements with simulated anteroposterior roentgenograms of the pelvis. Pelvic CT scans of 400 patients (54.3 years, range 18-100 years; 200 female) were reconstructed in the derotated coronal plane of the proximal femur and as CT-based simulated anteroposterior roentgenograms of the pelvis in the anterior pelvic plane. Femora were categorized as coxa vara (<120°), physiologic (≥120° to <135°), and coxa valga (≥135°). Intra- and inter-rater reliability were analyzed. Primary research question: Mean NSA for male adults was 129.6° (range 113.2°-148.2°; SD 5.9°) and 131.9° (range 107.1°-151.9°; SD 6.8°) for females in derotated coronal reconstructions. Age (p < 0.001 in both views) and sex influenced the NSA significantly (p = 0.002 and p < 0.001); no significant differences were found between sides (p = 0.722 and p = 0.955). Overall, an excellent reliability of repeated measurements of one or two observers was found (ICC 0.891-0.995). Secondary research question: NSA values measured in the simulated anteroposterior roentgenogram and the rotation corrected coronal reconstruction differed significantly (p < 0.001). While anteroposterior pelvis radiographs are susceptible to rotational errors, the coronal reconstruction of the proximal femur in the femoral neck plane allows the correct measurement of the NSA.

Oral Health Basics-What Every Pediatrician Should Know.

As soon as teeth are present, dental care should be discussed at every pediatric well-child visit. Many parents do not ask their pediatricians about dental care, assuming that it is the dentists' domain, but some families do ask lots of questions. Either way, pediatricians should discuss dental care at well visits, answering any questions and offering anticipatory guidance, especially on how to prevent caries. There are many questions from parents about dental care: how to brush, what kind of toothpaste to use, how to stop their child from grinding his or her teeth, whether or not pacifiers are bad for tooth development, and other inquiries that are addressed in the article. This article acts as a quick reference guide for pediatricians, so they are prepared to answer common questions about oral health. [Pediatr Ann. 2016;45(11):e379-e381.].

The aim of this study is to establish reference values for single-fibre electromyography (SFEMG) using concentric needles in a prospective, multicentre study. Voluntary or stimulated SFEMG at the extensor digitorum communis (EDC) or frontalis (FRO) muscles was conducted in 56-63 of a total of 69 normal subjects below the age of 60years at six Japanese institutes. The cut-off values for mean consecutive difference (MCD) of individual potentials were calculated using +2.5 SD or 95% prediction limit (one-tail) of the upper 10th percentile MCD value for individual subjects. The cut-off values for individual MCD (+2.5 SD) were 56.8μs for EDC-V (voluntary SFEMG for EDC), 58.8μs for EDC-S (stimulated SFEMG for EDC), 56.8μs for FRO-V (voluntary SFEMG for FRO) and 51.0μs for FRO-S (stimulated SFEMG for FRO). The false positive rates using these cut-off values were around 2%. The +2.5 SD and 95% prediction limit might be two optimal cut-off values, depending on the clinical question. The obtained reference values were larger than those reported previously using concentric needles, but might better coincide with conventional values. This is the first multicentre study reporting reference values for SFEMG using concentric needles. The way to determine cut-off values and the statistically correct definition of the percentile were discussed. Copyright © 2011 International Federation of Clinical Neurophysiology.

To refresh natural environmental concepts in science, science teacher have to attend a teacher training. In teacher training, all participant can have a good sharing and discussion with other science teacher. This study is the first step of science teacher training program held by education foundation in Bandung and attended by 20 science teacher from 18 Junior High School. The major aim of this study is gathering science teacher’s idea of environmental concepts. The core of questions used in this study are basic competencies linked with environmental concepts, environmental concepts that difficult to explain, the action to overcome difficulties and references in teaching environmental concepts. There are four major findings in this study. First finding, most environmental concepts are taught in 7th grade. Second finding, most difficult environmental concepts are found in 7th grade. Third finding, there are five actions to overcome difficulties. Fourth finding, science teacher use at least four references in mastering environmental concepts. After all, teacher training can be a solution to reduce difficulties in teaching environmental concepts.

Anticholinergics in the era of atypical antipsychotics: short-term or long-term treatment?

Anticholinergic agents are usually prescribed to prevent or treat antipsychotic-induced extrapyramidal symptoms. Their long-term benefits are questionable and they carry diverse adverse effects, including cognitive impairment and worsening of tardive dyskinesia. This literature review explores the impact of anticholinergic medication discontinuation on movement disorders, cognition and psychopathology in patients receiving antipsychotics. Medline, Embase and PsycInfo were searched from 1950 to July 2011 using "cessation /withdrawal /discontinuation /stopping" with "anticholinergic*" or "antiparkinson*" and "neuroleptic*" or "antipsychotic*". Additional articles were obtained by searching the bibliographies of relevant references. Earlier studies of anticholinergic agent discontinuation in patients receiving first-generation antipsychotics reported relapse rates of extrapyramidal symptoms between 4% and 80%, reflecting the heterogeneity of the studies. Two recent studies of patients prescribed second-generation antipsychotics obtained relapse rates of 4% and 33%. Some studies suggest improvement in tardive dyskinesia with cessation of anticholinergics. Four studies examined the effects of anticholinergic agent discontinuation on cognition and all observed an improvement post-discontinuation. Changes in symptoms of schizophrenia with anticholinergic discontinuation are conflicting, with more recent studies suggesting an improvement. Given their questionable benefit with continued use, clinicians should consider a gradual withdrawal of anticholinergic agents in stable patients receiving antipsychotics.

To identify gender differences in social support dimensions' effect on adults' leisure-time physical activity maintenance, type, and time. Longitudinal study of 1,278 non-faculty public employees at a university in Rio de Janeiro, RJ, Southeastern Brazil. Physical activity was evaluated using a dichotomous question with a two-week reference period, and further questions concerning leisure-time physical activity type (individual or group) and time spent on the activity. Social support was measured with the Medical Outcomes Study Social Support Scale. For the analysis, logistic regression models were adjusted separately by gender. A multinomial logistic regression showed an association between material support and individual activities among women (OR = 2.76; 95%CI 1.2;6.5). Affective support was associated with time spent on leisure-time physical activity only among men (OR = 1.80; 95%CI 1.1;3.2). All dimensions of social support that were examined influenced either the type of, or the time spent on, leisure-time physical activity. In some social support dimensions, the associations detected varied by gender. Future studies should attempt to elucidate the mechanisms involved in these gender differences.

Rate making is a complicated and time-consuming procedure. That it could benefit from judiciously chosen reforms is beyond question. This article covers several major areas of contention within the regulatory arena, all of which have been the subject of considerable debate in recent years. In an effort to find a compromise position between extremes, the author makes three specific suggestions that, if adopted, could enable parties involved to devote their time and resources to more fundamental questions regarding the regulated utility industries. 3 references.
