Boys' and girls' use of cognitive strategy when learning to play video games.

PubMed

Blumberg, Fran C; Sokol, Lori M

2004-04-01

The authors examined gender differences in the cognitive strategies that children use when they learn how to play a video game. They interviewed 2nd- and 5th-grade boys and girls about how often they played video games and what they did "when learning how to play a video game." The children's responses to the latter question were categorized as either internally or externally oriented (i.e., reading a manual vs. asking for help, respectively). The results indicated that more frequent players and older children were more likely to cite internally based strategies. No main effects of gender were found for the proportions of the internally vs. externally based strategies that were cited.

Sy, Alice; Wong, Eric; Boisvert, Leslie

2014-01-01

Abstract Objective To determine family medicine residents’ learning behaviour and preferences outside of clinical settings in order to help guide the development of an effective academic program that can maximize their learning. Design Retrospective descriptive analysis of academic learning logs submitted by residents as part of their academic training requirements between 2008 and 2011. Setting London, Ont. Participants All family medicine residents at Western University who had completed their academic program requirements (N = 72) by submitting 300 or more credits (1 credit = 1 hour). Main outcome measures Amount of time spent on various learning modalities, location where the learning took place, resources used for self-study, and the objective of the learning activity. Results A total of 72 residents completed their academic requirements during the study period and logged a total of 25 068 hours of academic learning. Residents chose to spend most of their academic time engaging in self-study (44%), attending staff physicians’ teaching sessions (20%), and participating in conferences, courses, or workshops (12%) and in postgraduate medical education sessions (12%). Textbooks (26%), medical journals (20%), and point-of-care resources (12%) were the 3 most common resources used for self-study. The hospital (32%), residents’ homes (32%), and family medicine clinics (14%) were the most frequently cited locations where academic learning occurred. While all physicians used a variety of educational activities, most residents (67%) chose self-study as their primary method of learning. The topic for academic learning appeared to have some influence on the learning modalities used by residents. Conclusion Residents used a variety of learning modalities and chose self-study over other more traditional modalities (eg, lectures) for most of their academic learning. A successful academic program must take into account residents’ various learning preferences and habits while providing guidance and training in the use of more effective learning methods and resources to maximize educational outcomes.

First Contact: Expectations of Beginning Astronomy Students

NASA Astrophysics Data System (ADS)

Lacey, T. L.; Slater, T. F.

1999-05-01

Three hundred seven undergraduate students enrolled in Introductory Astronomy were surveyed at the beginning of class to determine their expectations for course content. The course serves as a survey of astronomy for non-science majors and is a distribution course for general education core requirements. The course has no prerequisites, meets three times each week for 50 minutes, and represents three semester credit hours. The university catalog describes the course with the title "PHYSICS 101 - Mysteries of the Sky" and the official course description is: a survey of the struggle to understand the Universe and our place therein. The structure, growth, methods, and limitations of science will be illustrated using the development of astronomy as a vehicle. Present day views of the Universe are presented. Two questions were asked as open response items: What made you decide to take this course? and What do you expect to learn in this course? The reasons that students cited to take the course, in order of frequency, were: interested in astronomy, interesting or fun sounding course, required general education fulfillment, recommendation by peer. Secondary reasons cited were required for major or minor, general interest in science, and was available in the schedule. Tertiary reasons listed were recommendation by advisor or orientation leader, inflate grade point average, and heard good things about the teacher. The students' expectations about what they would learn in the course were numerous. The most common objects listed, in order of frequency, were: stars, constellations, planets, galaxies, black holes, solar system, comets, galaxies, asteroids, moon, and Sun. More interesting were the aspects not specifically related to astronomy. These were weather, atmosphere, UFOs and the unexplained, generally things in the sky. A mid-course survey suggests that students expected to learn more constellations and that the topics would be less in-depth.

Mapping the literature of pediatric nursing: update and implications for library services

PubMed Central

Watwood, Carol L.

2016-01-01

Objective The purpose of this study was to identify core journals and other types of literature cited in four major pediatric nursing journals and to characterize coverage of these resources in major bibliographic databases. The study was part of the “Mapping the Literature of Nursing Project” of the Medical Library Association's Nursing and Allied Health Resource Section. It updates a similar analysis published in 2006 and determines whether citation patterns have changed over time. Methods Cited references from articles published in 4 pediatric nursing journals between 2011 and 2013 were collected. Cited journal titles were ranked according to number of times cited and analyzed according to Bradford's Law of Scattering and the 80/20 rule to identify the most frequently cited journals. Five databases were surveyed to assess the coverage of the most-often-cited journals. The most frequently cited non-journal sources were also identified. Results Journals were the most frequently cited sources, followed by books, government documents, Internet resources, and miscellaneous resources. Most cited sources were cited within ten years of their publication, which was particularly true for government documents and Internet resources. Scopus had complete coverage of the most frequently cited journals, whereas PubMed had nearly complete coverage. Conclusions Compared with the 2006 study, the list of top-cited journals referenced by pediatric nursing researchers has remained relatively stable, but the number of cited journal titles has increased. Book citations have declined, and Internet and government document references have increased. These findings suggest that librarians should retain subscriptions to frequently cited journal titles, provide efficient document delivery of articles from infrequently used journals, de-emphasize but not eliminate books, and connect patrons with useful open-access Internet resources.

Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years. PMID:24675917

Objectives: This study analyzes and describes the literature of addictions treatment and indexing coverage for core journals in the field. Methods: Citations from three source journals for the years 2008 through 2010 were analyzed using the 2010 Mapping the Literature of Nursing and Allied Health Professions Project Protocol. The distribution of cited journals was analyzed by applying Bradford's Law of Scattering. Results: More than 40,000 citations were analyzed. Journals (2,655 unique titles) were the most frequently cited form of literature, with 10 journals providing one-third of the cited journal references. Drug and Alcohol Dependence was the most frequently cited journal. The frequency of cited addictions journals, formats cited, age of citations, and indexing coverage is identified. Conclusions: Addictions treatment literature is widely dispersed among multidisciplinary publications with relatively few publications providing most of the citations. Results of this study will help researchers, students, clinicians, and librarians identify the most important journals and bibliographic indexes in this field, as well as publishing opportunities.

Eligible articles identified were reviewed for key characteristics. The Oxford Centre for Evidence-Based Medicine guidelines were used in assessing the level of evidence. The number of citations varied (62 to 923 on List A and 218 to 2,859 on List B). Countries that contributed the majority of articles in both lists were the United States, Netherlands, United Kingdom, and Canada. No significant correlations were found between number of citations and number of years since published (p=0.451), number of authors (p=0.144), females in authorship (p=0.189), non-medical authors (p=0.869), number of institutions (p=0.452), and number of grants (p=0.143), but a strong correlation was found with number of countries involved (p=0.007). Application of the Oxford hierarchy of evidence showed that 36 articles were at levels 4 and 5 of evidence. This study found that research articles represented approximately one-third of PBL articles assessed and reported mainly on questionnaire-based studies. The most highly cited articles occupied top-ranking positions in the journals in which they were published. The lower level of evidence observed in most top-cited articles may reflect the significance of innovative ideas or content of these articles. These findings have implications for dental educators and dental researchers.

Objectives: The research provides an overview of the health care management literature and the indexing coverage of core journal literature. Method: Citations from five source journals for the years 2002 through 2004 were studied using the protocols of the Mapping the Literature of Allied Health Project and Mapping the Literature of Nursing Project. The productivity of cited journals was analyzed by applying Bradford's Law of Scattering. Results: Journals were the most frequently cited format, followed by books. Only 3.2% of the cited journal titles from all 5 source journals generated two-thirds of the cited titles. When only the health care management practitioner–oriented source journals were considered, two-thirds of the output of cited journal titles came from 10.8% of the titles. Science Citation Index and PubMed provided the best overall coverage of the titles cited by all 5 source journals, while the cited titles from the 2 practitioner-oriented journals were covered most completely by Social Sciences Citation Index and Business Source Complete. Conclusions: Health care management is a multidisciplinary field. Librarians must consider the needs of their users and assist them by providing the necessary materials and combination of indexes to access this field adequately. PMID:17443238

Older Australians: Structural barriers to learning in later life.

Learning in older age is associated with benefits including increases in skills, social interactions, self-satisfaction, coping ability, enjoyment, and resilience to age-related changes in the brain. It is also a fundamental component of active ageing and if active ageing objectives are to be met for the growing ageing population, barriers to learning need to be understood and addressed. This study aimed at determining the degree that structural factors deter people aged 55 years and older from engaging in learning activities. The data were obtained from survey (n=421) with a purposive sample of Australian Seniors aged 55 to 75+, and open ended follow up interviews (n=40). The survey responses to the 22 barriers to learning questions were ranked and quantified. The issues identified in the interviews shed further light on the survey data. The analyses revealed that factors related to educational institutions as well as infrastructure were commonly cited as barriers to participation in learning. In particular expense of educational programmes (55.1%), long travelling time (45.6%) other transportation difficulties (38.9%), lack of interest in offered programmes ((36.4) and lack of information about courses (31.1%) were seen as barriers. The interviews revealed and confirmed five main barriers; money, offerings of interest/availability, travel/transport, information, computer skills and being employed. The findings should provide policy makers, institutions, organizations and government with a list of areas where changes might be made so as to improve older people's opportunities for learning as they proceed through older age.

OBJECTIVES To identify the most cited articles in general surgery published by Brazilian authors. INTRODUCTION There are several ways for the international community to recognize the quality of a scientific article. Although controversial, the most widely used and reliable methodology to identify the importance of an article is citation analysis. METHODS A search using the Institute for Scientific Information citation database (Science Citation Index Expanded) was performed to identify highly cited Brazilian papers published in twenty-six highly cited general surgery journals, selected based on their elevated impact factors, from 1970 to 2009. Further analysis was done on the 65 most-cited papers. RESULTS We identified 1,713 Brazilian articles, from which nine papers emerged as classics (more than 100 citations received). For the Brazilian contributions, a total increase of about 21-fold was evident between 1970 and 2009. Although several topics were covered, articles covering trauma, oncology and organ transplantation were the most cited. The majority of classic studies were done with international cooperation. CONCLUSIONS This study identified the most influential Brazilian articles published in internationally renowned general surgery journals. PMID:20535371

Caillon, J; Bouju, G; Grall-Bronnec, M

2014-03-01

Despite the popularity of video games, few studies have been conducted in France on their use. The objective of this study was to gather data from a sample of French video game players to learn more about this population. This approach also aimed to examine whether differences exist between adolescent and adult gamers in terms of their motivations to play and whether this practice met the criteria for problem video game playing. A questionnaire collecting sociodemographic data and assessing the problems associated with the use of video games, as well as motivations to play, was distributed during a video game festival and on the Internet. A total of 778 people responded to the questionnaire. The results showed that there were few differences between adolescent and adult gamers. Both groups had an intense video game habit. The majority of them sometimes had the feeling of losing control of their use and sacrificed other activities to play video games. This last dimension was most frequently cited by adults. The feeling of spending more time playing was most frequently cited by adolescents. Concerning motivations to play, the two groups differed only on the score of the "social" dimension, significantly higher among adolescents. Copyright © 2014 Elsevier Masson SAS.

Sweeney, Nancy M; Tucker, Joanne; Reynosa, Brenda; Glaser, Dale

2006-02-01

This study measured the effectiveness of a 9 a.m. nutrition break after it had been implemented for 1 academic year at an inner-city high school. Effectiveness was measured by student participation rates, student and teacher evaluations of hunger-associated symptoms experienced by students, and teacher evaluations of the effects on the learning environment. Sixty-nine percent of students participated. The most frequently cited reason for nonparticipation was dislike of the food offered (53%), with an additional 15% citing problems with food distribution. As the frequency of participation rose, the frequency of inability to focus, tiredness, stomachache, headache, and midmorning hunger fell. All of the associations were statistically significant except for headache. Seventy-four percent of staff stated that the nutrition break had positive effects on the learning environment, and 71% referred fewer students to the school nurse.

Chambers, James D.; Saret, Cayla J.; Anderson, Jordan E.; Deverka, Patricia A.; Douglas, Michael P.; Phillips, Kathryn A.

2017-01-01

Objectives The aim of this study was to examine the evidence payers cited in their coverage policies for multi-gene panels and sequencing tests (panels), and to compare these findings with the evidence payers cited in their coverage policies for other types of medical interventions. Methods We used the University of California at San Francisco TRANSPERS Payer Coverage Registry to identify coverage policies for panels issued by five of the largest US private payers. We reviewed each policy and categorized the evidence cited within as: clinical studies, systematic reviews, technology assessments, cost-effectiveness analyses (CEAs), budget impact studies, and clinical guidelines. We compared the evidence cited in these coverage policies for panels with the evidence cited in policies for other intervention types (pharmaceuticals, medical devices, diagnostic tests and imaging, and surgical interventions) as reported in a previous study. Results Fifty-five coverage policies for panels were included. On average, payers cited clinical guidelines in 84 percent of their coverage policies (range, 73–100 percent), clinical studies in 69 percent (50–87 percent), technology assessments 47 percent (33–86 percent), systematic reviews or meta-analyses 31 percent (7–71 percent), and CEAs 5 percent (0–7 percent). No payers cited budget impact studies in their policies. Payers less often cited clinical studies, systematic reviews, technology assessments, and CEAs in their coverage policies for panels than in their policies for other intervention types. Payers cited clinical guidelines in a comparable proportion of policies for panels and other technology types. Conclusions Payers in our sample less often cited clinical studies and other evidence types in their coverage policies for panels than they did in their coverage policies for other types of medical interventions.

Objectives: The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals. Method: Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford's Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007. Results: Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications. Conclusions: Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline. PMID:21753912

Costs of success: Financial implications of implementation of active learning in introductory physics courses for students and administrators

NASA Astrophysics Data System (ADS)

Brewe, Eric; Dou, Remy; Shand, Robert

2018-02-01

Although active learning is supported by strong evidence of efficacy in undergraduate science instruction, institutions of higher education have yet to embrace comprehensive change. Costs of transforming instruction are regularly cited as a key factor in not adopting active-learning instructional practices. Some cite that alternative methods to stadium-style, lecture-based education are not financially viable to an academic department. This paper examines that argument by presenting an ingredients approach to estimating costs of two instructional methods used in introductory university physics courses at a large public U.S. university. We use a metric common in educational economics, cost effectiveness (CE), which is the total cost per student passing the class. We then compare the CE of traditional, passive-learning lecture courses to those of a well-studied, active-learning curriculum (Modeling Instruction) as a way of evaluating the claim that active learning is cost prohibitive. Our findings are that the Modeling Instruction approach has a higher cost per passing student (MI = 1 ,030 /passing student vs Trad = 790 /passing student). These results are discussed from perspectives of university administrators, students, and taxpayers. We consider how MI would need to adapt in order to make the benefits of active learning (particularly higher pass rates and gains on multiple measured student outcomes) available in a cost-neutral setting. This approach aims to provide a methodology to better inform decision makers balancing financial, personnel, and curricular considerations.

To assess the frequency of use by and perceived impact of various educational technologies on student pharmacists. Data were obtained using a validated, Web-based survey instrument designed to evaluate the frequency of use and impact on learning of various technologies used in educating first-, second-, and third-year student pharmacists. Basic demographic data also were collected and analyzed. The majority (89.4%) of the 179 respondents were comfortable with the technology used in the academic program. The most frequently used technologies for educational purposes were in class electronic presentations, course materials posted on the school Web site, and e-mail. The technologies cited as having the most beneficial impact on learning were course materials posted on the Web site and in-class electronic presentations, and those cited as most detrimental were video-teleconferencing and online testing. Compared to the course textbook, students reported more frequent use of technologies such as electronic course materials, presentations, digital lecture recordings, e-mail, and hand-held devices. Because students' opinions of educational technologies varied, colleges and schools should incorporate educational technologies that students frequently use and that positively impact learning.

Interactive computer-assisted instruction in acid-base physiology for mobile computer platforms.

PubMed

Longmuir, Kenneth J

2014-03-01

In this project, the traditional lecture hall presentation of acid-base physiology in the first-year medical school curriculum was replaced by interactive, computer-assisted instruction designed primarily for the iPad and other mobile computer platforms. Three learning modules were developed, each with ∼20 screens of information, on the subjects of the CO2-bicarbonate buffer system, other body buffer systems, and acid-base disorders. Five clinical case modules were also developed. For the learning modules, the interactive, active learning activities were primarily step-by-step learner control of explanations of complex physiological concepts, usually presented graphically. For the clinical cases, the active learning activities were primarily question-and-answer exercises that related clinical findings to the relevant basic science concepts. The student response was remarkably positive, with the interactive, active learning aspect of the instruction cited as the most important feature. Also, students cited the self-paced instruction, extensive use of interactive graphics, and side-by-side presentation of text and graphics as positive features. Most students reported that it took less time to study the subject matter with this online instruction compared with subject matter presented in the lecture hall. However, the approach to learning was highly examination driven, with most students delaying the study of the subject matter until a few days before the scheduled examination. Wider implementation of active learning computer-assisted instruction will require that instructors present subject matter interactively, that students fully embrace the responsibilities of independent learning, and that institutional administrations measure instructional effort by criteria other than scheduled hours of instruction.

2018-05-09

Antimicrobial prescribing behaviour is first established during medical study, but teachers often cite lack of time as an important problem in the implementation of antimicrobial stewardship in the medical curriculum. The use of electronic learning (e-learning) is a potentially time-efficient solution, but its effectiveness in changing long-term prescribing behaviour in medical students is as yet unknown. We performed a prospective controlled intervention study of the long-term effects of a short interactive e-learning course among fourth year medical students in a Dutch university. The e-learning was temporarily implemented as a non-compulsory course during a 6 week period. Six months later, all students underwent an infectious disease-based objective structured clinical examination (OSCE) aimed at simulating postgraduate prescribing. If they passed, each student did the OSCE only once. We created a control group of students from a period when the e-learning was not implemented. Main outcomes were the OSCE pass percentage and knowledge, drug choice and overall scores. We used propensity scores to create equal comparisons. We included 71 students in the intervention group and 285 students in the control group. E-learning participation in the intervention group was 81%. The OSCE pass percentage was 86% in the control group versus 97% in the intervention group (+11%, OR 5.9, 95% CI 1.7-20.0). OSCE overall, knowledge and drug choice grades (1-10) were also significantly higher in the intervention group (differences +0.31, +0.31 and +0.51, respectively). E-learning during a limited period can significantly improve medical students' performance of an antimicrobial therapeutic consultation in a situation simulating clinical practice 6 months later.

2016-01-01

Bibliometric analysis highlights the key topics and publications, which have shaped surgical education. Here, the 100 most cited articles in the arena of surgical education were analyzed. Thomson Reuters Web of Science was interrogated using the keyword search terms "surgery" and ("learning" or "skills" or "competence" or "assessment" or "training" or "procedure-based assessments" or "performance" or "technical skills" or "curriculum" or "education" or "mentoring"] to identify all English language full articles, and the 100 most cited articles were analyzed by topic, journal, author, year, institution, and country of origin. A total of 403,733 eligible articles were returned and the median citation number was 164 (range: 107-1018). The most cited article (by Seymour, Yale University School of Medicine, Annals of Surgery, 1018 citations) focused on the use of virtual reality surgical simulation training. Annals of Surgery published the highest number of articles and received the most citations (n = 16, 3715 citations). The countries with the greatest number of publications were the USA (n = 45), Canada (n = 19), and the UK (n = 18). The commonest topics included simulation (n = 45) and assessment of clinical competence (n = 40). Surgical skill acquisition and assessment was the area of focus of 85% of the most cited contemporary articles, and this study provides the most cited references, serving as a guide as to what makes a citable published work in the field of surgical education.

Improving Neuromuscular Monitoring and Reducing Residual Neuromuscular Blockade With E-Learning: Protocol for the Multicenter Interrupted Time Series INVERT Study

PubMed Central

Mathiesen, Ole; Hägi-Pedersen, Daniel; Skovgaard, Lene Theil; Østergaard, Doris; Engbaek, Jens; Gätke, Mona Ring

2017-01-01

Background Muscle relaxants facilitate endotracheal intubation under general anesthesia and improve surgical conditions. Residual neuromuscular blockade occurs when the patient is still partially paralyzed when awakened after surgery. The condition is associated with subjective discomfort and an increased risk of respiratory complications. Use of an objective neuromuscular monitoring device may prevent residual block. Despite this, many anesthetists refrain from using the device. Efforts to increase the use of objective monitoring are time consuming and require the presence of expert personnel. A neuromuscular monitoring e-learning module might support consistent use of neuromuscular monitoring devices. Objective The aim of the study is to assess the effect of a neuromuscular monitoring e-learning module on anesthesia staff’s use of objective neuromuscular monitoring and the incidence of residual neuromuscular blockade in surgical patients at 6 Danish teaching hospitals. Methods In this interrupted time series study, we are collecting data repeatedly, in consecutive 3-week periods, before and after the intervention, and we will analyze the effect using segmented regression analysis. Anesthesia departments in the Zealand Region of Denmark are included, and data from all patients receiving a muscle relaxant are collected from the anesthesia information management system MetaVision. We will assess the effect of the module on all levels of potential effect: staff’s knowledge and skills, patient care practice, and patient outcomes. The primary outcome is use of neuromuscular monitoring in patients according to the type of muscle relaxant received. Secondary outcomes include last recorded train-of-four value, administration of reversal agents, and time to discharge from the postanesthesia care unit as well as a multiple-choice test to assess knowledge. The e-learning module was developed based on a needs assessment process, including focus group interviews, surveys, and expert opinions. Results The e-learning module was implemented in 6 anesthesia departments on 21 November 2016. Currently, we are collecting postintervention data. The final dataset will include data from more than 10,000 anesthesia procedures. We expect to publish the results in late 2017 or early 2018. Conclusions With a dataset consisting of thousands of general anesthesia procedures, the INVERT study will assess whether an e-learning module can increase anesthetists’ use of neuromuscular monitoring.

1994-11-01

The treatment of adolescent sexual offenders (ASO) has its theoretical underpinnings in social learning theory. Although social learning theory has been frequently cited in literature, a comprehensive application of this theory, as applied to practice, has not been mapped out. The social learning and social cognitive theories of Bandura appear to be particularly relevant to the group treatment of this population. The application of these theories to practice, as demonstrated in a program model, is discussed as a means of demonstrating how theory-driven practice methods can be developed.

[Learning how to learn for specialist further education].

PubMed

Breuer, G; Lütcke, B; St Pierre, M; Hüttl, S

2017-02-01

The world of medicine is becoming from year to year more complex. This necessitates efficient learning processes, which incorporate the principles of adult education but with unchanged periods of further education. The subject matter must be processed, organized, visualized, networked and comprehended. The learning process should be voluntary and self-driven with the aim of learning the profession and becoming an expert in a specialist field. Learning is an individual process. Despite this, the constantly cited learning styles are nowadays more controversial. An important factor is a healthy mixture of blended learning methods, which also use new technical possibilities. These include a multitude of e‑learning options and simulations, which partly enable situative learning in a "shielded" environment. An exemplary role model of the teacher and feedback for the person in training also remain core and sustainable aspects in medical further education.

Abstract Objective To document the scope of the teaching and evaluation of ethics and professionalism in Canadian family medicine postgraduate training programs, and to identify barriers to the teaching and evaluation of ethics and professionalism. Design A survey was developed in collaboration with the Committee on Ethics of the College of Family Physicians of Canada. The data are reported descriptively and in aggregate. Setting Canadian postgraduate family medicine training programs. Participants Between June and December of 2008, all 17 Canadian postgraduate family medicine training programs were invited to participate. Main outcome measures The first part of the survey explored the structure, resources, methods, scheduled hours, and barriers to teaching ethics and professionalism. The second section focused on end-of-rotation evaluations, other evaluation strategies, and barriers related to the evaluation of ethics and professionalism. Results Eighty-eight percent of programs completed the survey. Most respondents (87%) had learning objectives specifically for ethics and professionalism, and 87% had family doctors with training or interest in the area leading their efforts. Two-thirds of responding programs had less than 10 hours of scheduled instruction per year, and the most common barriers to effective teaching were the need for faculty development, competing learning needs, and lack of resident interest. Ninety-three percent of respondents assessed ethics and professionalism on their end-of-rotation evaluations, with 86% assessing specific domains. The most common barriers to evaluation were a lack of suitable tools and a lack of faculty comfort and interest. Conclusion By far most Canadian family medicine postgraduate training programs had learning objectives and designated faculty leads in ethics and professionalism, yet there was little curricular time dedicated to these areas and a perceived lack of resident interest and faculty expertise. Most programs evaluated ethics and professionalism as part of their end-of-rotation evaluations, but only a small number used novel means of evaluation, and most cited a lack of suitable assessment tools as an important barrier.

Factors associated with young adults delaying and forgoing driving licenses: results from Britain.

Le Vine, Scott; Polak, John

2014-01-01

To identify the reasons that young adults (age 17-29) in Britain delay or forgo driving license acquisition. Using year 2010 British National Travel Survey microdata, we first analyze self-reported reasons (including their prioritisation) for not holding a full car driving license and then estimate a logistic regression model for license-holding to investigate additional factors, several of which extend from previous studies. This study also employs a novel segmentation approach to analyze the sets of reasons that individual young adults cite for not driving. These results show that, despite the lack of a graduated driving license system at present, many young adults indicate that issues associated with the driving license acquisition process are the main reason they do not hold a full driving license. About 3 in 10 young adults can be interpreted as not viewing driving as a priority, though half of those without a license are either learning to drive or are deterred principally by the cost of learning. We calculate that after their 17th birthday (the age of eligibility for a full driving license) young adults spend a mean of 1.7 years learning to drive. Young adults citing the costs of insurance or car purchase are likely to cite them as secondary rather than the main reason for not driving, whereas those citing physical/health difficulties are very likely to cite this as the main reason they do not drive. Two distinct groups of young people are identified that both indicate that costs deter them from driving-one group that is less well off financially and that indicates that costs alone are the primary deterrent and one that reports that other reasons also apply and is better off. Status as an international migrant was found to be an important factor, net of confounding variables, for identifying that a young adult in Britain does not hold a driving license. Further research is needed to understand the relative saliency of plausible causal mechanisms for this finding. We also report that both personal income and household income are independently positively associated with license-holding but that (intuitively) the relationship of license holding with a young adult's own personal income is the much stronger of the two. On the basis of these findings, it can be concluded that a number of previously underappreciated factors appear to be linked with young British adults not acquiring a driving license.

Research on the value of medical library services: does it make an impact in the health care literature?*

2004-01-01

Objective: To evaluate the impact in the health care literature of research articles that provided evidence of the value of library services (including MEDLINE) as an element of quality health care. Data Sources/Selection: Four research articles on the relationship between use of library services and quality health care were selected as “primary articles” from a MEDLINE search using appropriate Medical Subject Heading. Primary articles met the following criteria: written in English, reported research, related to clinical care, and published before 1995. Data Extraction: The technique of citation analysis was used to measure the impact of the primary articles on the subsequent literature. The number, authorship, type, and publication venue of articles citing the primary articles were determined using ISI Web of Science, MEDLINE, other electronic resources, and the citing articles themselves. For the 146 English-language citing articles, the article type (i.e., advocacy, instructional, research) was noted; and, for those that reported research, the use to which the author put the cited material was determined. Results: The primary articles were cited more often than the average articles published that year in the same journals. At the time of the study each article had been cited almost every year since publication. Of the 146 citing articles written in English, 43% were written by librarians, 38% by physicians, 12% by librarians with physicians. The majority were published in medical journals, followed in order of decreasing frequency by the Bulletin of the Medical Library Association, information science journals, and health administration journals. Conclusions: The results of this study demonstrate that published research on the value of medical library services has an impact on the literature. These articles are read and cited and continue to be of value. PMID:14762461

Bibliometric analysis of the American Journal of Veterinary Research to produce a list of core veterinary medicine journals

PubMed Central

Crawley-Low, Jill

2006-01-01

Objective: Bibliometric techniques were used to analyze the citation patterns of researchers publishing in the American Journal of Veterinary Research (AJVR). Methods: The more than 25,000 bibliographic references appearing in the AJVR from 2001 to 2003 were examined for material type, date of publication, and frequency of journals cited. Journal titles were ranked in decreasing order of productivity to create a core list of journals most frequently used by veterinary medical researchers. Results: The majority of items cited were journals (88.8%), followed by books (9.8%) and gray literature (2.1%). Current sources of information were favored; 65% of the journals and 77% of the books were published in 1990 or later. Dividing the cited articles into 3 even zones revealed that 24 journals produced 7,361 cited articles in the first zone. One hundred thirty-nine journals were responsible for 7,414 cited articles in zone 2, and 1,409 journals produced 7,422 cited articles in zone 3. Conclusions: A core collection of veterinary medicine journals would include 49 veterinary medicine journals from zones 1 and 2. Libraries supporting a veterinary curriculum or veterinary research should also include veterinary medical journals from Zone 3, as well as provide access to journals in non-veterinary subjects such as biochemistry, virology, orthopedics, and surgery and a selection of general science and medical journals.

Nuclear power: renaissance or relapse? Global climate change and long-term Three Mile Island activists' narratives.

PubMed

Culley, Marci R; Angelique, Holly

2010-06-01

Community narratives are increasingly important as people move towards an ecologically sustainable society. Global climate change is a multi-faceted problem with multiple stakeholders. The voices of affected communities must be heard as we make decisions of global significance. We document the narratives of long-term anti-nuclear activists near the Three Mile Island (TMI) nuclear power plant who speak out in the dawn of a nuclear renaissance/relapse. While nuclear power is marketed as a "green" solution to global warming, their narratives reveal three areas for consideration; (1) significant problems with nuclear technology, (2) lessons "not" learned from the TMI disaster, and (3) hopes for a sustainable future. Nuclear waste, untrustworthy officials and economic issues were among the problems cited. Deceptive shaping of public opinion, nuclear illiteracy, and an aging anti-nuclear movement were reasons cited for the lessons not learned. However, many remain optimistic and envision increased participation to create an ecologically-balanced world.

The top 100 cited articles on urological emergencies: A bibliometric analysis

PubMed Central

Dokur, Mehmet

2018-01-01

Objective In this study, we bibliometrically evaluated the top 100 cited articles on urological emergencies published since 1975 with a multidisciplinary and interdisciplinary perspective. Material and methods We obtained the data for this study from the Thomson Reuters Web of Science and PubMed. We determined 360 articles which were related directly or indirectly to urological emergencies between 1975 and 2017 and analyzed retrospectively the top 100 cited articles among these. Results The mean citation impact factor of the top 100 cited articles was 25.8±50.1 (range: 4–467) between 1991 and 2014. We determined that classical articles were cited for 2588 times and the total number of self-citations was 23 (0.8%). Highest publication rate per year was in 2006 (n=9). Among the institutions which published ≥2 articles per year University of Texas led the way with 5 articles. The top 100 articles came from 27 countries and 58% of these are from the USA (n=29), the United Kingdom (n=23) and Germany (n=6). For the top 3 journals of the 33 of top 100 articles most frequently cited were published in journals with an impact factor ≥2 namely, Journal of Urology (n=15), British Journal of Urology International (n=13) and Urology (n=5) respectively. The most frequently cited main topics were penile emergencies with 22 articles and acute scrotal problems with 15 articles. Most of the classical articles on urological emergencies were based on clinical researches (n=95) and also we found that the average level of evidence for the top 100 cited articles was 4.16 (range: 1–5). Mostly preferred publishing language was English among this scientific papers (n=90). Conclusion Although not considered as a completely unbiased and adequate criterion for scientific evaluations, analysis of the top 100 cited articles provides us with important current data on urological emergencies.

2017-01-01

Objectives To analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns. Design Quantitative content analysis. Setting/sample Full text of 22 general newspapers in 14 countries over the period 2008–2015, collected from LexisNexis. The 14 countries have been categorised into four regions: the USA, the UK, Western World (European countries other than the UK, and Australia, New Zealand and Canada) and Rest of the World (other countries). Main outcome measure Press citations of four medical journals (two American: NEJM and JAMA; and two British: The Lancet and The BMJ) in 22 newspapers. Results British and American newspapers cited some of the four analysed medical journals about three times a week in 2008–2015 (weekly mean 3.2 and 2.7 citations, respectively); the newspapers from other Western countries did so about once a week (weekly mean 1.1), and those from the Rest of the World cited them about once a month (monthly mean 1.1). The New York Times cited above all other newspapers (weekly mean 4.7). The analysis showed the existence of three national citation patterns in the daily press: American newspapers cited mostly American journals (70.0% of citations), British newspapers cited mostly British journals (86.5%) and the rest of the analysed press cited more British journals than American ones. The Lancet was the most cited journal in the press of almost all Western countries outside the USA and the UK. Multivariate correspondence analysis confirmed the national patterns and showed that over 85% of the citation data variability is retained in just one single new variable: the national dimension. Conclusion British and American newspapers are the ones that cite the four analysed medical journals more often, showing a domestic preference for their respective national journals; non-British and non-American newspapers show a common international citation pattern.

Citation analysis reflects the scientific recognition and influential performance of an article in the scientific community. The objective of this study was to identify and characterize the 100 most cited articles on oral submucous fibrosis (OSF). A list of 100 most cited articles related to OSF was retrieved from the Science Citation Index-Expanded tool of Scopus database in May 2018.The articles were further reviewed, and basic information was recorded including the number of citations, citation density, journals, with its impact factor, category and quartile, publication year, authors, institution and country of origin, article type and level of evidence. Descriptive statistics were used to summarize the results. The most frequently cited article received 780 citations, while the least frequently cited article received 49 (mean107.5 citations per article). There were 38 different journals with Journal of Oral Pathology and Medicine having the most citations (n = 22).The 100 most cited articles were published from 1966 to 2013, with 81% published after 1990.Thirteen authors listed 5 or more articles in the top 100 list and India was found to be the most prolific country with 38 articles. In terms of article type, there were 72 research articles and 28 review articles. This first citation analysis of the 100 most cited articles render a historical perspective on the progress of research in the field of OSF and enables the comprehensive identification and recognition of the most important and relevant research topics concerned.

The effectiveness of humane teaching methods in veterinary education.

PubMed

Knight, Andrew

2007-01-01

Animal use resulting in harm or death has historically played an integral role in veterinary education, in disciplines such as surgery, physiology, biochemistry, anatomy, pharmacology, and parasitology. However, many non-harmful alternatives now exist, including computer simulations, high quality videos, ''ethically-sourced cadavers'' such as from animals euthanased for medical reasons, preserved specimens, models and surgical simulators, non-invasive self-experimentation, and supervised clinical experiences. Veterinary students seeking to use such methods often face strong opposition from faculty members, who usually cite concerns about their teaching efficacy. Consequently, studies of veterinary students were reviewed comparing learning outcomes generated by non-harmful teaching methods with those achieved by harmful animal use. Of eleven published from 1989 to 2006, nine assessed surgical training--historically the discipline involving greatest harmful animal use. 45.5% (5/11) demonstrated superior learning outcomes using more humane alternatives. Another 45.5% (5/11) demonstrated equivalent learning outcomes, and 9.1% (1/11) demonstrated inferior learning outcomes. Twenty one studies of non-veterinary students in related academic disciplines were also published from 1968 to 2004. 38.1% (8/21) demonstrated superior, 52.4% (11/21) demonstrated equivalent, and 9.5% (2/21) demonstrated inferior learning outcomes using humane alternatives. Twenty nine papers in which comparison with harmful animal use did not occur illustrated additional benefits of humane teaching methods in veterinary education, including: time and cost savings, enhanced potential for customisation and repeatability of the learning exercise, increased student confidence and satisfaction, increased compliance with animal use legislation, elimination of objections to the use of purpose-killed animals, and integration of clinical perspectives and ethics early in the curriculum. The evidence demonstrates that veterinary educators can best serve their students and animals, while minimising financial and time burdens, by introducing well-designed teaching methods not reliant on harmful animal use.

Photometric monitoring of three BL Lacertae objects in 1993-1998

NASA Astrophysics Data System (ADS)

Bai, J. M.; Xie, G. Z.; Li, K. H.; Zhang, X.; Liu, W. W.

1999-05-01

The results of optical photometric (BVRI) monitoring of three BL Lac objects over a time interval of about four years are presented. The sources are three classical radio-selected BL Lac objects, BL Lac, OJ 287 and PKS 0735+178. During our observation OJ 287 was in the stage of a large periodic outburst which consisted of at least two peaks. Almost all the observations obtained over consecutive nights detected intranight variations. In 1995 and 1996 BL Lac kept in faint states, with fewer and smaller rapid flares and fluctuations. On the contrary, in late 1997 BL Lac was at the stage of a large outburst, accompanied with much more large amplitude rapid flares and fluctuations. PKS 0735+178 was almost at its faint end from 1994 to early 1998. Over this time interval, the intraday variations and microvariations in PKS 0735+178 were rare and the amplitude was very small, except a rapid darkening of ~ 0.4 mag on 24 January 1995. Previous work by \\cite[Webb et al. (1988);]{web88} \\cite[Wagner et al. (1996);]{wag96} \\cite[Pian et al. (1997)]{pia97} also showed the same behaviour of variability as BL Lac and PKS 0735+178 in BL Lac, S5 0716+714, PKS 2155-304, respectively. We propose that the motion of orientation of the relativistic jet in a BL Lac object be responsible for these variability behaviours.

De la Garza-Ramos, Rafael; Benvenutti-Regato, Mario; Caro-Osorio, Enrique

2016-05-01

OBJECTIVE The authors' objective was to identify the 100 most-cited research articles in the field of spinal oncology. METHODS The Thomson Reuters Web of Science service was queried for the years 1864-2015 without language restrictions. Articles were sorted in descending order of the number of times they were cited by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. Levels of evidence were assigned on the basis of the North American Spine Society criteria. RESULTS The authors identified the 100 most-cited articles in spinal oncology, which collectively had been cited 20,771 times at the time of this writing. The oldest article on this top 100 list had been published in 1931, and the most recent in 2008; the most prolific decade was the 1990s, with 34 articles on this list having been published during that period. There were 4 studies with Level I evidence, 3 with Level II evidence, 9 with Level III evidence, 70 with Level IV evidence, and 2 with Level V evidence; levels of evidence were not assigned to 12 studies because they were not on therapeutic, prognostic, or diagnostic topics. Thirty-one unique journals contributed to the 100 articles, with the Journal of Neurosurgery contributing most of the articles (n = 25). The specialties covered included neurosurgery, orthopedic surgery, neurology, radiation oncology, and pathology. Sixty-seven articles reported clinical outcomes. The most common country of article origin was the United States (n = 62), followed by Canada (n = 8) and France (n = 7). The most common topics were spinal metastases (n = 35), intramedullary tumors (n = 18), chordoma (n = 17), intradural tumors (n = 7), vertebroplasty/kyphoplasty (n = 7), primary bone tumors (n = 6), and others (n = 10). One researcher had authored 6 studies on the top 100 list, and 7 authors had 3 studies each on this list. CONCLUSIONS This study identified the 100 most-cited research articles in the area of spinal oncology. The studies highlighted the multidisciplinary and multimodal nature of spinal tumor management. Recognition of historical articles may guide future spinal oncology research.

Otolaryngology--head and neck surgery in undergraduate medical education: advances and innovations.

PubMed

Fung, Kevin

2015-02-01

Medical students graduate with the knowledge and skills to be undifferentiated general physicians. Otolaryngology-head and neck surgery (OtoHNS) is an essential component of primary healthcare, but is disproportionately under-represented in undergraduate medical education (UME). Advances and innovations in educational technology may represent an exciting and creative solution to this important problem. Failure to meet this educational need will result in substantial downstream effects in primary healthcare delivery. The objectives of this study were to 1) demonstrate current deficits in OtoHNS teaching at the UME level; 2) develop, validate, and critically appraise educational innovations that may enrich OtoHNS teaching in medical school curricula; and 3) propose a process for standardization of learning objectives for OtoHNS in UME as it relates to development and deployment of such educational tools. A white paper, prepared as a Triological Society thesis, which consolidates a prospective 10-year investigation of the problem of and potential solutions for under-representation of OtoHNS in UME. Cited datasets include multicenter surveys, cohort studies, and prospective, randomized controlled trials. A series of published and unpublished data were synthesized that addresses the following: 1) the current state of OtoHNS teaching at the UME level with respect to content, volume, structure, and methods; and 2) educational innovations including e-learning and simulation with emphasis on validity and learning effectiveness. Educational innovations specific to postgraduate (residency) training were excluded. Data support the observation that there is uniformly disproportionate under-representation of OtoHNS within UME curricula. Medical school graduates, especially those pursuing primary care specialties, report poor overall comfort levels in managing OtoHNS problems. A series of novel teaching methods were developed and validated using e-learning and simulation. Selected technologies may have a role in medical student teaching. It has been shown that e-learning has limited value in teaching complex spatial anatomy to novice learners, but good value in teaching basic clinical knowledge and selected technical skills. The role of simulation as it pertains to the novice learner is evolving. Important factors to consider during development of these tools include: 1) knowledge base and learning style of the learner, 2) complexity and nature of the learning objectives, 3) understanding the features and limitations of different technological genres, and 4) a team approach to module development. There remains a role for traditional teaching paradigms such as lectures, labs, and standardized patients; however, the choice of instructional genre should be fundamentally tailored to the nature of the learning outcomes. Enriching OtoHNS teaching in medical school is essential optimize primary care delivered to patients. Although e-learning and simulation are broadly accepted and desirable by today's medical students, these technologies should be woven into the fabric of UME pedagogical principles judiciously, and only after empiric assessment. Foundational to the development and implementation of these technologies is the framework of standardized competency-based learning objectives, common to all graduating medical students.

A Categorical Content Analysis of Highly Cited Literature Related to Trends and Issues in Special Education.

PubMed

Arden, Sarah V; Pentimonti, Jill M; Cooray, Rochana; Jackson, Stephanie

2017-07-01

This investigation employs categorical content analysis processes as a mechanism to examine trends and issues in a sampling of highly cited (100+) literature in special education journals. The authors had two goals: (a) broadly identifying trends across publication type, content area, and methodology and (b) specifically identifying articles with disaggregated outcomes for students with learning disabilities (LD). Content analyses were conducted across highly cited (100+) articles published during a 20-year period (1992-2013) in a sample ( n = 3) of journals focused primarily on LD, and in one broad, cross-categorical journal recognized for its impact in the field. Results indicated trends in the article type (i.e., commentary and position papers), content (i.e., reading and behavior), and methodology (i.e., small proportions of experimental and quasi-experimental designs). Results also revealed stability in the proportion of intervention research studies when compared to previous analyses and a decline in the proportion of those that disaggregated data specifically for students with LD.

Why Veterinary Medical Educators Should Embrace Cumulative Final Exams.

PubMed

Royal, Kenneth D

The topic of cumulative final examinations often elicits polarizing opinions from veterinary medical educators. While some faculty prefer cumulative finals, there are many who perceive these types of examinations as problematic. Specifically, faculty often cite cumulative examinations are more likely to cause students' greater stress, which may in turn result in negative student evaluations of teaching. Cumulative finals also restrict the number of items one may present to students on most recent material. While these cited disadvantages may have some merit, the advantages of cumulative examinations far exceed the disadvantages. The purpose of this article is to discuss the advantages of cumulative examinations with respect to learning evidence, grade/score validity, fairness issues, and implications for academic policy.

Mapping the literature of occupational therapy: an update

PubMed Central

Potter, Jonathan

2010-01-01

Objectives: This study updated Reed's 1999 “Mapping the Literature of Occupational Therapy.” An analysis of citation patterns and indexing coverage was undertaken to identify the core literature of occupational therapy and to determine access to that literature. Methods: Citations from three source journals for the years 2006 through 2008 were studied following the common methodology of the “Mapping the Literature of Allied Health Project.” Bradford's Law of Scattering was applied to analyze the productivity of cited journals. A comparative analysis of indexing was conducted across three bibliographic databases. Results: A total of 364 articles cited 10,425 references. Journals were the most frequently cited format, accounting for 65.3% of the references, an increase of 4.1% over the 1999 study. Approximately one-third of the journal references cited a cluster of 9 journals, with the American Journal of Occupational Therapy dominating the field. An additional 120 journals were identified as moderately important based on times cited. CINAHL provided the most comprehensive indexing of core journals, while MEDLINE provided the best overall coverage. Conclusions: Occupational therapy is a multidisciplinary field with a strong core identity and an increasingly diverse literature. Indexing has improved overall since 1999, but gaps in the coverage are still evident. PMID:20648258

The 300 most cited articles published in periodontology.

PubMed

Faggion, Clovis Mariano; Málaga, Lilian; Monje, Alberto; Trescher, Anna-Lena; Listl, Stefan; Alarcón, Marco Antonio

2017-07-01

It is important to evaluate the characteristics of the most cited articles in any specialty. The number of citations may be a proxy for clinical and research activity. The objectives of the present methodological study were (1) to report the characteristics of the 300 most cited articles in periodontology and (2) to explore the association of these characteristics with the number of citations. We searched in the Web of Science database for the 300 most cited articles published in periodontology on June 15, 2015. We described characteristics of the articles such as type of study, type of scientific journal, topic reported, year of publication, affiliation of the first author of the article, and impact factor. Linear regression analysis was used to investigate associations of these variables with the number of citations. The search retrieved approximately 155,356 publications; out of the studies that met the eligibility criteria, the 300 most cited were included for analysis. Comprising more than 50 % of the included articles, basic biology and the detection of bacteria were the most prevalent topics. Narrative reviews were the most frequent type of article (27 % of the sample). Regression analysis demonstrated that some characteristics, for example "narrative reviews," are more prone to be cited than others. We conclude that scientific evolution in periodontology has been based more on narrative reviews than on reproducible systematic reviews. Future research is encouraged to elucidate the extent to which scientific progress is improved through systematic compared with narrative reviews.

Critical Approaches to Lifelong Education

NASA Astrophysics Data System (ADS)

Preston, Rosemary

1999-11-01

This paper argues that contemporary interest in lifelong learning can be seen as an artefact of the market. It points out how the attractive vocabulary associated with personal development and empowerment often masks other economic and social purposes. Bearing in mind the social function of education, the author compares the strategies for the promotion of lifelong learning designed for those in "included social categories" with the policies designed for those in marginal and excluded positions. It concludes by challenging its own position by citing positive learner experience in each case.

Software and the Scientist: Coding and Citation Practices in Geodynamics

NASA Astrophysics Data System (ADS)

Hwang, Lorraine; Fish, Allison; Soito, Laura; Smith, MacKenzie; Kellogg, Louise H.

2017-11-01

In geodynamics as in other scientific areas, computation has become a core component of research, complementing field observation, laboratory analysis, experiment, and theory. Computational tools for data analysis, mapping, visualization, modeling, and simulation are essential for all aspects of the scientific workflow. Specialized scientific software is often developed by geodynamicists for their own use, and this effort represents a distinctive intellectual contribution. Drawing on a geodynamics community that focuses on developing and disseminating scientific software, we assess the current practices of software development and attribution, as well as attitudes about the need and best practices for software citation. We analyzed publications by participants in the Computational Infrastructure for Geodynamics and conducted mixed method surveys of the solid earth geophysics community. From this we learned that coding skills are typically learned informally. Participants considered good code as trusted, reusable, readable, and not overly complex and considered a good coder as one that participates in the community in an open and reasonable manor contributing to both long- and short-term community projects. Participants strongly supported citing software reflected by the high rate a software package was named in the literature and the high rate of citations in the references. However, lacking are clear instructions from developers on how to cite and education of users on what to cite. In addition, citations did not always lead to discoverability of the resource. A unique identifier to the software package itself, community education, and citation tools would contribute to better attribution practices.

Pitfalls of CITES implementation in Nepal: a policy gap analysis.

PubMed

Dongol, Yogesh; Heinen, Joel T

2012-08-01

Implementation of policy involves multiple agencies operating at multiple levels in facilitating processes and actions to accomplish desired results. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) was developed and implemented to regulate and control international wildlife trade, but violations of the agreement are widespread and growing worldwide, including in Nepal. This study attempts to understand how domestic CITES policies are translated into action and what effect actions and processes have on compliance. In doing so, this study provides insights into the implementation and enforcement pitfalls of national legislation that explain CITES violations in Nepal. Primarily, we used 26 key informants interviews to learn opinions of experts, and the grounded theory approach for further qualitative data analysis. In addition, we used Najman's (1995) policy implementation analysis framework to explain gaps. Many interrelated variables in the content of the policy, commitment and capacity of the agencies, the roles of clients and coalitions and contextual issues were observed. Variables that emerged suggest pitfalls in the regulatory policy represented by low probability of detection, arrest and punishment. Moreover, redistributive policies in buffer zones of protected areas are needed into perpetuity to benefit locals. Also, conservation organizations' support for building public and political salience is imperative.

Ward, Max; Doran, Joseph; Paskhover, Boris; Mammis, Antonios

2018-06-01

Bibliometric analysis is a commonly used analytic tool for objective determination of the most influential and peer-recognized articles within a given field. This study is the first bibliometric analysis of the literature in the field of invasive neuromodulation, excluding deep brain stimulation. The objectives of this study are to identify the 50 most cited articles in invasive neuromodulation, provide an overview of the literature to assist in clinical education, and evaluate the effect of impact factor on manuscript recognition. Bibliometric analysis was performed using the Science Citation Index from the Institute for Scientific Information, accessed through the Web of Science. Search terms relevant to the field of invasive neuromodulation were used to identify the 50 most cited journal articles between 1900 and 2016. The median number of citations was 236 (range, 173-578). The most common topics among the articles were vagus nerve stimulation (n = 24), spinal cord stimulation (n = 9), and motor cortex stimulation (n = 6). Median journal impact factor was 5.57. Most of these articles (n = 19) contained level I, II, or III evidence. This analysis provides a brief look into the most cited articles within the field, many of which evaluated innovated procedures and therapies that helped to drive surgical neuromodulation forward. These landmark articles contain vital clinical and educational information that remains relevant to clinicians and students within the field and provide insight into areas of expanding research. Journal impact factor may play a significant role in determining the literary relevance and general awareness of invasive neuromodulation studies. Copyright © 2018 Elsevier Inc. All rights reserved.

Service-Learning in Undergraduate Nursing Education: Where is the Reflection?

PubMed

Brown, Janet M; Schmidt, Nola A

2016-01-01

Service-Learning is recognized as a valuable pedagogy that involves experiential learning, reflection, and reciprocal learning. Reflection is a critical component because it assists students to develop critical thinking and social awareness as they reflect upon their experiential learning with community partners. Although there is a proliferation of literature about service-learning, upon closer examination, it is apparent that some authors do not place emphasis on reflection when reporting on service-learning projects. This begs the question, "Where is the reflection?" The purpose of this article is to provide an overview and describe misrepresentations and exemplars of service-learning. After providing an overview of service-learning, examples of how service-learning is misrepresented in the literature are discussed. Exemplars of service-learning are also cited. Calling attention to how service-learning is reported in the literature will increase awareness about the need to critically evaluate articles for evidence of reflection.

Lloyd, B W; Becker, D

2007-08-01

To determine what paediatric specialist registrars think of the educational supervision they have received and what advice they would give to a consultant who wanted to be a more effective educational supervisor. A questionnaire study. The North Thames Deanery, UK. 129 year 3, 4 or 5 paediatric specialist registrars in the North Thames Deanery. Reported value of educational supervision on a Likert scale; what elements of educational supervision were reported to be most useful; what elements of educational supervision were reported to be done poorly; what advice would specialist registrars give to a consultant who wanted to be a more effective educational supervisor. 86/129 specialist registrars responded (67%). The mean score on the Likert scale (0-a complete waste of time; 100-excellent) was 57 with 37% of respondents giving a score of less than 50. The most valued aspects of educational supervision were: feedback on performance--cited by 50 respondents (56% of respondents); career advice--cited by 43 (48%); objective setting--cited by 36 (40%); pastoral support--cited by 25 (28%). Aspects of educational supervision that were reported to be often not done well were: commitment to educational supervision--cited by 44 respondents (49% of respondents); ensuring sessions are bleep-free-cited by 43 (48%); listening rather than talking--cited by 23 (26%); being encouraging--cited by 18 (20%). Advice to consultants about how to improve educational supervision included: listen rather than talk; be encouraging; treat the trainee as an individual with individual needs. We can find no other study of trainees' views about how educational supervision can be improved. Although some trainees found educational supervision very valuable, many did not. Educational supervision should only be carried out by consultants who are committed to the task. An educational supervisor should listen carefully in order to understand the trainee's individual ambitions and needs, should provide specific feedback on performance and should be encouraging.

Academic Impact of Qualitative Studies in Healthcare: Bibliometric Analysis

Mori, Hiroko; Nakayama, Takeo

2013-01-01

Context Although qualitative studies are becoming more appreciated in healthcare, the number of publications of quality studies remains low. Little is known about the frequency and characteristics of citation in qualitative studies. Objective To compare the academic impact of qualitative studies to that of two quantitative studies: systematic reviews and randomized controlled trials. Methods Publications in BMJ between 1997 and 2006 (BMJ’s median impact factor was 7.04 during this period) employing qualitative methods were matched to two quantitative studies appearing the same year using PubMed. Using Web of Science, citations within a 24-month publication period were determined. Additionally, three hypotheses were examined: qualitative studies are 1) infrequently cited in original articles or reviews; 2) rarely cited by authors in non-English-speaking countries; and 3) more frequently cited in non-medical disciplines (e.g., psychology or sociology). Results A total of 121 qualitative studies, 270 systematic reviews, and 515 randomised controlled trials were retrieved. Qualitative studies were cited a total of 1,089 times, with a median of 7.00 times (range, 0–34) for each study. Matched systematic reviews and randomized controlled trials were cited 2,411times and 1,600 times, respectively. With respect to citing documents, original articles and reviews exceeded 60% for each study design. Relative to quantitative studies, qualitative studies were cited more often by authors in English-speaking countries. With respect to subject area, medical disciplines were more frequently cited than non-medical disciplines for all three study designs (>80%). Conclusion The median number of citations for qualitative studies was almost the same as the median of BMJ’s impact factor during the survey period. For a suitable evaluation of qualitative studies in healthcare, it will be necessary to develop a reporting framework and include explicit discussions of clinical implications when reporting findings. Coordination between researchers and editors will be needed to achieve this goal. PMID:23516404

Prospects for arable farm uptake of Short Rotation Coppice willow and miscanthus in England.

PubMed

Glithero, Neryssa J; Wilson, Paul; Ramsden, Stephen J

2013-07-01

Biomass will play a role in the UK meeting EU targets on renewable energy use. Short Rotation Coppice (SRC) and miscanthus are potential biomass feedstocks; however, supply will rely on farmer willingness to grow these crops. Despite attractive crop establishment grants for dedicated energy crops (DECs) in the UK, uptake remains low. Drawing on results from an on-farm survey with 244 English arable farmers, 81.6% (87.7%) of farmers would not consider growing miscanthus (SRC), while respectively, 17.2% (11.9%) would consider growing and 1.2% (0.4%) were currently growing these crops. Farmer age, location, land ownership, farm type, farm size and farmer education level were not significant factors in determining acceptance of DECs. The main reasons cited for not growing DECs were impacts on land quality, lack of appropriate machinery, commitment of land for a long period of time, time to financial return and profitability. Reasons cited for willingness to grow DECs included land quality, ease of crop management, commitment of land for a long period of time, and profitability. Farmers cited a range of 'moral' (e.g. should not be using land for energy crops when there is a shortage of food), land quality, knowledge, profit and current farming practice comments as reasons for not growing DECs, while those willing to grow DECs cited interest in renewable energy, willingness to consider new crops, and low labour needs as rationale for their interest. Farm business objectives indicated that maximising profit and quality of life were most frequently cited as very important objectives. Previous research in the UK indicates that farmers in arable areas are unlikely to convert large areas of land to DECs, even where these farmers have an interest and willingness to grow them. Assuming that those farmers interested in growing DECs converted 9.29% (average percentage of arable land set-aside between 1996 and 2005) of their utilised agricultural area to these crops, 50,700 ha and 89,900 ha of SRC and miscanthus would, respectively, be grown on English arable farms. While farm business objectives were not identified as key determinants of DEC acceptance, enhanced information exchange through extension agents, providing market security and considering land reversion grants post-production are potential policy considerations.

Teixeira, Renan Kleber Costa; Yamaki, Vitor Nagai; Rosa, Rita de Cássia Rodrigues; de Barros, Rui Sergio Monteiro; Botelho, Nara Macedo

2014-01-01

Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often. PMID:26229879

Završnik, Jernej; del Torso, Stefano; Blažun Vošner, Helena

2016-01-01

Objectives ‘Sleeping beauties’, i.e. publications that are not cited for a long while, present interesting findings in science. This study analysed the citation trends of sleeping beauties in paediatric research. Methods The study used bibliometric software to analyse the papers citing sleeping beauties in paediatric research, to understand the context in which paediatric sleeping beauties were finally cited and the impact of these sleeping beauties on paediatric research. Results Two paediatric sleeping beauties, addressing medical homes and the transition from paediatric to adult health care, respectively, awakened in response to organizational needs. Both presented novel concepts of paediatric service organization that became important because of an increased need for optimization of services. Conclusion All sleeping beauties bring new knowledge that becomes important only after several years. Paediatric sleeping beauties exhibited unique characteristics; however, their presence in paediatric research shows that knowledge acquisition in paediatrics resembles that in other disciplines.

2017-01-01

Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. Two searches were conducted in the Web of Science in June 2016 using a list of education-related search terms. We searched 19 EM journals for education articles as well as all other literature for EM education-related articles. Articles identified were reviewed for citation count, article type, journal, authors, and publication year. With regards to EM journals, the greatest number of articles were classified as articles/reviews, followed by research articles on topics such as deliberate practice (cited 266 times) and cognitive errors (cited 201 times). In contrast in the non-EM journals, research articles were predominant. Both searches found several simulation and ultrasound articles to be included. The most common EM journal was Academic Emergency Medicine (n = 18), and Academic Medicine was the most common non-EM journal (n=5). A reasonable number of articles included external funding sources (6 EM articles and 13 non-EM articles.). This study identified the most frequently cited medical education articles in the field of EM education, published in EM journals as well as all other journals indexed in Web of Science. The results identify impactful articles to medical education, providing a resource to educators while identifying trends that may be used to guide EM educational research and publishing efforts.

Uysal, Erdal

2017-01-01

Objective This study aimed to analyze 100 most cited articles in breast cancer research. Materials and Methods The data in this study were obtained by a search conducted on the Web of Science (WOS). In brief, the term “breast cancer” was typed in the search box of WOS basic research including all the years and the data. The analysis was carried out by compiling the top 100 cited articles in the shortlist as sorted by the journals, categories of the studies, the countries, the centers, the authors and the publication date. No statistical methods were used in the study. All data were reported as percentages, numbers and bar charts on tables. Results Our findings showed that the most frequently cited article received 7609 citations to date. Most articles were published in the New England Journal of Medicine. 81% of the studies originated from the USA. The National Institutes of Health (NIH USA) was ranked the first with 21% and it was followed by Harvard University in terms of number of published articles. 42% of the articles were published under the category of medicine and general internal medicine. Conclusion Top 100 most cited articles originated from the United States. The highest number of articles among the top 100 articles were published in New England Journal of Medicine and National Institutes of Health NIH USA was the leading institutes published the most articles.

Mapping the literature of maternal-child/gynecologic nursing

PubMed Central

Jacobs, Susan Kaplan

2006-01-01

Objectives: As part of a project to map the literature of nursing, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association, this study identifies core journals cited in maternal-child/gynecologic nursing and the indexing services that access the cited journals. Methods: Three source journals were selected and subjected to a citation analysis of articles from 1996 to 1998. Results: Journals were the most frequently cited format (74.1%), followed by books (19.7%), miscellaneous (4.2%), and government documents (1.9%). Bradford's Law of Scattering was applied to the results, ranking cited journal references in descending order. One-third of the citations were found in a core of 14 journal titles; one-third were dispersed among a middle zone of 100 titles; and the remaining third were scattered in a larger zone of 1,194 titles. Indexing coverage for the core titles was most comprehensive in PubMed/MEDLINE, followed by Science Citation Index and CINAHL. Conclusion: The core of journals cited in this nursing specialty revealed a large number of medical titles, thus, the biomedical databases provide the best access. The interdisciplinary nature of maternal-child/ gynecologic nursing topics dictates that social sciences databases are an important adjunct. The study results will assist librarians in collection development, provide end users with guidelines for selecting databases, and influence database producers to consider extending coverage to identified titles.

2006-01-01

Objectives: As part of a project to map the literature of nursing, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association, this study identifies core journals cited by general or “popular” US nursing journals and the indexing services that cover the cited journals. Methods: Three journals were selected for analysis: American Journal of Nursing, Nursing 96–98, and RN. The source journals were subjected to a citation analysis of articles from 1996 to 1998, followed by an analysis of database access to the most frequently cited journal titles. Results: Cited formats included journals (63.7%), books (26.6%), government documents (3.0%), Internet (0.5%), and miscellaneous (6.2%). Cited references were relatively current; most (86.6%) were published in the current decade. One-third of the citations were found in a core of 24 journal titles; one-third were dispersed among a middle zone of 94 titles; and the remaining third were scattered in a larger zone of 694 titles. Indexing coverage for the core titles was most comprehensive in PubMed/MEDLINE, followed by CINAHL and Science Citation Index. Conclusions: Results support the popular (not scholarly) nature of these titles. While not a good source for original research, they fulfill a key role of disseminating nursing knowledge with their relevantly current citations to a broad variety of sources. PMID:16710462

PubMed Central

Lipitz-Snyderman, Allison; Kale, Minal; Robbins, Laura; Pfister, David; Fortier, Elizabeth; Pocus, Valerie; Chimonas, Susan; Weingart, Saul N

2018-01-01

Objective Relatively little attention has been devoted to the role of communication between physicians as a mechanism for individual and organisational learning about diagnostic delays. This study’s objective was to elicit physicians’ perceptions about and experiences with communication among physicians regarding diagnostic delays in cancer. Design, setting, participants Qualitative analysis based on seven focus groups. Fifty-one physicians affiliated with three New York-based academic medical centres participated, with six to nine subjects per group. We used content analysis to identify commonalities among primary care physicians and specialists (ie, medical and surgical oncologists). Primary outcome measure Perceptions and experiences with physician-to-physician communication about delays in cancer diagnosis. Results Our analysis identified five major themes: openness to communication, benefits of communication, fears about giving and receiving feedback, infrastructure barriers to communication and overcoming barriers to communication. Subjects valued communication about cancer diagnostic delays, but they had many concerns and fears about providing and receiving feedback in practice. Subjects expressed reluctance to communicate if there was insufficient information to attribute responsibility, if it would have no direct benefit or if it would jeopardise their existing relationships. They supported sensitive approaches to conveying information, as they feared eliciting or being subject to feelings of incompetence or shame. Subjects also cited organisational barriers. They offered suggestions that might facilitate communication about delays. Conclusions Addressing the barriers to communication among physicians about diagnostic delays is needed to promote a culture of learning across specialties and institutions. Supporting open and honest discussions about diagnostic delays may help build safer health systems. PMID:28655713

PubMed

Nam, Jason; Do, Woo S; Stinner, Daniel J; Wenke, Joseph C; Orman, Jean A; Kragh, John F

The objective of this study was to identify the most-cited peer-reviewed combat orthopedic and extremity injury articles published during the past 70 years. Orthopedic trauma presents ongoing challenges to both US civilian and military healthcare personnel. Improvements in combat trauma and extremity injury survival and quality of life are the result of advances in orthopedic trauma research. The Web of Science (including Science Citation Index) was searched for the most cited articles related to combat orthopedic trauma, published from 1940 to 2013. The most-cited article was by Owens et al. (Journal of Orthopaedic Trauma, 2007; 137 citations). Between the 1990s and 2000s, there was a 256% increase in the number of highly cited publications. A total of 69% of the articles were on the topics of comorbid vascular trauma (25%), epidemiology (23%), or orthopedic trauma (21%). This study identifies some of the most important contributions to combat orthopedic trauma and research and the areas of greatest scientific interest to the specialty during the past seven decades and highlights key research that has contributed to the evolution of modern combat orthopedic traumatology. 2017.

Mapping the literature of radiation therapy

Delwiche, Frances A.

2013-01-01

Objective: This study characterizes the literature of the radiation therapy profession, identifies the journals most frequently cited by authors writing in this discipline, and determines the level of coverage of these journals by major bibliographic indexes. Method: Cited references from three discipline-specific source journals were analyzed according to the Mapping the Literature of Allied Health Project Protocol of the Nursing and Allied Health Resources Section of the Medical Library Association. Bradford's Law of Scattering was applied to all journal references to identify the most frequently cited journal titles. Results: Journal references constituted 77.8% of the total, with books, government documents, Internet sites, and miscellaneous sources making up the remainder. Although a total of 908 journal titles were cited overall, approximately one-third of the journal citations came from just 11 journals. MEDLINE and Scopus provided the most comprehensive indexing of the journal titles in Zones 1 and 2. The source journals were indexed only by CINAHL and Scopus. Conclusion: The knowledgebase of radiation therapy draws heavily from the fields of oncology, radiology, medical physics, and nursing. Discipline-specific publications are not currently well covered by major indexing services, and those wishing to conduct comprehensive literature searches should search multiple resources.

The effects of portfolio purchasing on a specialized subject collection

PubMed Central

Murphy, Sarah Anne

2007-01-01

Objective: To examine the impact of portfolio purchasing on a small, highly specialized medical collection at The Ohio State University. Methodology: In this citation analysis, cited references for articles published by faculty in the College of Veterinary Medicine between 2000 and 2004 were collected and analyzed to determine whether The Ohio State University Libraries provided print or electronic access to the publications cited or the publishers of the cited journals, and whether the university purchased a subscription to each journal or received the subscription through a consortium-sponsored portfolio purchasing agreement. Results: Of the 419 journals veterinary faculty cited more than 10 times, only 13 (3.1%) were in Zone 1, and 63 (15.0%) were in Zone 2 of the Bradford distribution, a citation analysis model which demonstrates that a small number of journals account for the bulk of literature utilized in any established field. Of these, only 23 (5.5%) were procured through an OhioLINK or other consortium portfolio purchasing agreement. Discussion/Conclusion: The costs of acquiring a publisher's portfolio, even through a consortium, should be balanced with the costs of purchasing content required to provide a balanced collection for all user populations.

PubMed

Stutts, J C; Reinfurt, D W; Rodgman, E A

2001-01-01

Five years (1995-1999) of national Crashworthiness Data System (CDS) data are analyzed to determine the role of driver distraction in traffic crashes and the specific sources of this distraction. Results show that 8.3 percent of the drivers were distracted at the time of their crash; after adjustment for the large percentage of drivers with unknown distraction status, the percentage rose to 12.9 percent. The most frequently cited sources of driver distraction were persons, objects or events outside the vehicle (29.4% of distracted drivers), adjusting the radio, tape or CD player (11.4%), and other occupants in the vehicle (10.9%). Other specific distractions (moving objects in vehicle, other objects brought into vehicle, adjusting vehicle or climate controls, eating and drinking, cell phones, and smoking) were each cited in only one to four percent of the cases. The likelihood of being distracted and the source of distraction varied by driver age but not by gender. Results are discussed in light of the limitations inherent in the CDS and other crash data, and the need for expanded data collection initiatives.

Citing geospatial feature inventories with XML manifests

NASA Astrophysics Data System (ADS)

Bose, R.; McGarva, G.

2006-12-01

Today published scientific papers include a growing number of citations for online information sources that either complement or replace printed journals and books. We anticipate this same trend for cartographic citations used in the geosciences, following advances in web mapping and geographic feature-based services. Instead of using traditional libraries to resolve citations for print material, the geospatial citation life cycle will include requesting inventories of objects or geographic features from distributed geospatial data repositories. Using a case study from the UK Ordnance Survey MasterMap database, which is illustrative of geographic object-based products in general, we propose citing inventories of geographic objects using XML feature manifests. These manifests: (1) serve as a portable listing of sets of versioned features; (2) could be used as citations within the identification portion of an international geospatial metadata standard; (3) could be incorporated into geospatial data transfer formats such as GML; but (4) can be resolved only with comprehensive, curated repositories of current and historic data. This work has implications for any researcher who foresees the need to make or resolve references to online geospatial databases.

BACKGROUND Physicians increasingly face the challenge of managing clinical encounters with patients from a range of cultural backgrounds. Despite widespread interest in cross-cultural care, little is known about resident physicians' perceptions of what will best enable them to provide quality care to diverse patient populations. OBJECTIVES To assess medicine residents' (1) perceptions of cross-cultural care, (2) barriers to care, and (3) training experiences and recommendations. DESIGN, SETTING, AND PATIENTS Qualitative individual interviews were conducted with 26 third-year medicine residents at Massachusetts General Hospital in Boston (response rate = 87%). Interviews were recorded, transcribed, and analyzed. RESULTS Despite significant interest in cross-cultural care, almost all of the residents reported very little training during residency. Most had gained cross-cultural skills through informal learning. A few were skeptical about formal training, and some expressed concern that it is impossible to understand every culture. Challenges to the delivery of cross-cultural care included managing patients with limited English proficiency, who involve family in critical decision making, and who have beliefs about disease that vary from the biomedical model. Residents cited many implications to these barriers, ranging from negatively impacting the patient-physician relationship to compromised care. Training recommendations included making changes to the educational climate and informal and formal training mechanisms. CONCLUSIONS If cross-cultural education is to be successful, it must take into account residents' perspectives and be focused on overcoming residents' cited barriers. It is important to convey that cross-cultural education is a set of skills that can be taught and applied, in a time-efficient manner, rather than requiring an insurmountable knowledge base.

New ideas and their acceptance. As it has related to preservation of chordae tendinea and certain other discoveries.

PubMed

Lillehei, C W

1995-10-01

The significant benefits of preserving chordal-papillary muscle integrity in mitral valve replacement took some two decades to become widely accepted. Familiarity with history clearly tells us that this paradox between our dedication to "new ideas" on the one hand, and opposition to their acceptance on the other has existed for hundreds of years. Most "new ideas" have been surrounded by controversy and opposition before wide acceptance. Selected examples from history are cited beginning with Roger Bacon in the 13th century, and continuing with Galileo, Semmelweiss, Lister, and Forssmann. The author cites two notable examples from his personal experiences. They occurred during the development of open heart surgery, and another during the development of the rigid bileaflet cardiac prosthesis, now known as the St. Jude cardiac prosthesis. Some of the basic reasons for this inevitable opposition are: an innate skepticism over anything "new." Simplicity is often resented, as well as any need to change patterns of behavior/habits. Determination, persistence, stubbornness are the most important components for successful research. In addition, the successful innovator must learn to expect opposition and not be deterred by it, but rather must learn to take sustenance from it, and "learn to thrive upon opposition." In conclusion, these observations and suggestions are summarized in a satire on "The Seven Ages in the Evolution of an Idea--with particular reference to the critic."

Objective To report attitudes to retirement of late-career doctors. Design Questionnaires sent in 2014 to all UK medical graduates of 1974 and 1977. Setting United Kingdom. Participants 3695 medical graduates. Main outcome measures Factors which influenced doctors’ decisions to retire and factors which encouraged doctors to remain in work. Results The response rate was 85% (3695/4369). 55% of respondents overall were still working in medicine (whether they had not retired or had retired and returned; 61% of men, 43% of women). Of the retirees, 67% retired when they had originally planned to, and 28% had changed their retirement plans. Fifty per cent of retired doctors cited ‘increased time for leisure/other interests’ as a reason; 43% cited ‘pressure of work’. Women (21%) were more likely than men (11%) to retire for family reasons. Women (27%) were more likely than men (9%) to retire because of the retirement of their spouse. General practitioners (GPs) were more likely than doctors in other specialties to cite ‘pressure of work’. Anaesthetists and GPs were more likely than doctors in other specialties to cite the ‘possibility of deteriorating skill/competence’. Radiologists, surgeons, obstetricians and gynaecologists, and anaesthetists were most likely to cite ‘not wanting to do out-of-hours work’. Doctors who were still working were asked what would encourage them to stay in medicine for longer. Factors cited most frequently were ‘reduced impact of work-related bureaucracy’ (cited by 45%) and ‘workload reduction/shorter hours’ (42%). Men (30%) were more motivated than women (20%) by ‘financial incentivisation’. Surgeons were most motivated by ‘reduction of on-call or emergency commitments’. Conclusions Retention policy should address ways of optimising the clinical contribution of senior doctors while offering reduced workloads in the areas of bureaucracy and working hours, particularly in respect of emergency commitments.

Introduction Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. Methods Two searches were conducted in the Web of Science in June 2016 using a list of education-related search terms. We searched 19 EM journals for education articles as well as all other literature for EM education-related articles. Articles identified were reviewed for citation count, article type, journal, authors, and publication year. Results With regards to EM journals, the greatest number of articles were classified as articles/reviews, followed by research articles on topics such as deliberate practice (cited 266 times) and cognitive errors (cited 201 times). In contrast in the non-EM journals, research articles were predominant. Both searches found several simulation and ultrasound articles to be included. The most common EM journal was Academic Emergency Medicine (n = 18), and Academic Medicine was the most common non-EM journal (n=5). A reasonable number of articles included external funding sources (6 EM articles and 13 non-EM articles.) Conclusion This study identified the most frequently cited medical education articles in the field of EM education, published in EM journals as well as all other journals indexed in Web of Science. The results identify impactful articles to medical education, providing a resource to educators while identifying trends that may be used to guide EM educational research and publishing efforts.

Analysis of the number of citations within a given specialty provides information on the classic publications of that specialty. The goals of this study were to identify the 50 most cited articles on rotator cuff repair and to analyze various characteristics of these articles. The ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was used to conduct a search for the term rotator cuff repair. The 50 most cited articles were retrieved, and the following objective characteristics of each article were recorded: number of times cited, citation density, journal, country of origin, and language. The following subjective characteristics of each article were also recorded: article type (clinical vs basic science), article subtype, and level of evidence for clinical articles. Of the 50 most cited articles on rotator cuff repair, the number of citations ranged from 138 to 677 (mean, 232±133 citations) and citation density ranged from 3.8 to 53.5 citations per year (mean, 16.9±9.2 citations per year). The articles were published between 1974 and 2011, with most of the articles published in the 2000s (29 articles), followed by the 1990s (16 articles). The articles originated from 8 countries, with the United States accounting for 30 articles (60%). Overall, 66% of the articles were clinical and 34% were basic science. The most common article subtype was the clinical case series (48%). Of the 33 clinical articles, 24 (73%) were level IV. Among the 50 most cited articles on rotator cuff repair, the case series was the most common article subtype, showing the effect that publication of preliminary outcomes and new surgical techniques has had on surgeons performing rotator cuff repair.

Objectives While numerous cell phone use while driving laws have been passed among states, little information exists regarding who gets cited for these traffic infractions and how much these laws are enforced at the state-level within the USA. Design Cross-sectional, descriptive study. Setting 14 states and the District of Columbia. Participants Those receiving cell phone use while driving citations within included states from 2007 to 2013. Primary outcome Demographic characteristics of cited drivers were assessed. Rates of infractions per 100 000 licensed in-state drivers per year for various cell phone use while driving violations were calculated. Results Drivers were cited for hand-held use violations (n=2.5 million) more than texting (n=14 682) or young driver all cell phone bans (n=342). Among states that provided data for all traffic violations, cell phone use while driving citations comprised 1% of all written citations. Regardless of ban type, males (68.2%) were cited more frequently than females. Drivers 25–64 years of age (90.8%) were more likely to be cited for hand-held phone use. The average yearly rate of infractions per 100 000 licensed in-state drivers from 2010–2013 was 5.8 for texting bans, 2607 for hand-held bans, and 9954 for any traffic violation. Conclusions Among cited drivers, age and sex differences existed by the type of ban violated. State-level enforcement appeared sparse. Due to the potential serious consequences of cell phone use while driving in the USA, more enforcement and targeted public safety campaigns are likely needed. PMID:27301485

Learner factors associated with radical conceptual change among undergraduates

NASA Astrophysics Data System (ADS)

Olson, Joanne Kay

Students frequently enter learning situations with knowledge inconsistent with scientific views. One goal of science instruction is to enable students to construct scientifically accepted ideas while rejecting inaccurate constructs. This process is called conceptual change. This study examined factors associated with students at three levels of conceptual change to elucidate possible influences on the conceptual change process. Factors studied included motivation (including utility value, interest, attainment value, mood, self efficacy, and task difficulty), prior experiences with science, perceptions of the nature of science, connections to objects or events outside the classroom, and specific activities that helped students learn. Four science classes for undergraduate preservice elementary teachers participated in the study, conducted during a three week unit on electricity. Data sources included concept maps, drawings, reflective journal entries, quizzes, a science autobiography assignment, and interviews. Concept maps, drawings, and quizzes were analyzed, and students were placed into high, moderate, and low conceptual change groups. Of the ninety-eight students in the study, fifty-seven were interviewed. Perhaps the most important finding of this study relates to the assessment of conceptual change. Interviews were conducted two months after the unit, and many items on the concept maps had decayed from students' memories. This indicates that time is an important factor. In addition, interview-derived data demonstrated conceptual change levels; concept maps were insufficient to indicate the depth of students' understanding. Factors associated with conceptual change include self efficacy and interest in topic. In addition, moderate conceptual change students cited specific activities as having helped them learn. Low and high students focused on the method of instruction rather than specific activities. Factors not found to be associated with conceptual change include: utility value, mood, task difficulty, and prior experiences with science, and connections to objects and events outside the classroom. Attainment value, perceptions of the nature of science, and mood cannot be ruled out as possible factors due to the problematic nature of assessing them within the context of this study.

A Multiscale Vision Model and Applications to Astronomical Image and Data Analyses

NASA Astrophysics Data System (ADS)

Bijaoui, A.; Slezak, E.; Vandame, B.

Many researches were carried out on the automated identification of the astrophy sical sources, and their relevant measurements. Some vision models have been developed for this task, their use depending on the image content. We have developed a multiscale vision model (MVM) \\cite{BR95} well suited for analyzing complex structures such like interstellar clouds, galaxies, or cluster of galaxies. Our model is based on a redundant wavelet transform. For each scale we detect significant wavelet coefficients by application of a decision rule based on their probability density functions (PDF) under the hypothesis of a uniform distribution. In the case of a Poisson noise, this PDF can be determined from the autoconvolution of the wavelet function histogram \\cite{SLB93}. We may also apply Anscombe's transform, scale by scale in order to take into account the integrated number of events at each scale \\cite{FSB98}. Our aim is to compute an image of all detected structural features. MVM allows us to build oriented trees from the neighbouring of significant wavelet coefficients. Each tree is also divided into subtrees taking into account the maxima along the scale axis. This leads to identify objects in the scale space, and then to restore their images by classical inverse methods. This model works only if the sampling is correct at each scale. It is not generally the case for the orthogonal wavelets, so that we apply the so-called `a trous algorithm \\cite{BSM94} or a specific pyramidal one \\cite{RBV98}. It leads to ext ract superimposed objets of different size, and it gives for each of them a separate image, from which we can obtain position, flux and p attern parameters. We have applied these methods to different kinds of images, photographic plates, CCD frames or X-ray images. We have only to change the statistical rule for extr acting significant coefficients to adapt the model from an image class to another one. We have also applied this model to extract clusters hierarchically distributed or to identify regions devoid of objects from galaxy counts.

Improving Neuromuscular Monitoring and Reducing Residual Neuromuscular Blockade With E-Learning: Protocol for the Multicenter Interrupted Time Series INVERT Study.

Muscle relaxants facilitate endotracheal intubation under general anesthesia and improve surgical conditions. Residual neuromuscular blockade occurs when the patient is still partially paralyzed when awakened after surgery. The condition is associated with subjective discomfort and an increased risk of respiratory complications. Use of an objective neuromuscular monitoring device may prevent residual block. Despite this, many anesthetists refrain from using the device. Efforts to increase the use of objective monitoring are time consuming and require the presence of expert personnel. A neuromuscular monitoring e-learning module might support consistent use of neuromuscular monitoring devices. The aim of the study is to assess the effect of a neuromuscular monitoring e-learning module on anesthesia staff's use of objective neuromuscular monitoring and the incidence of residual neuromuscular blockade in surgical patients at 6 Danish teaching hospitals. In this interrupted time series study, we are collecting data repeatedly, in consecutive 3-week periods, before and after the intervention, and we will analyze the effect using segmented regression analysis. Anesthesia departments in the Zealand Region of Denmark are included, and data from all patients receiving a muscle relaxant are collected from the anesthesia information management system MetaVision. We will assess the effect of the module on all levels of potential effect: staff's knowledge and skills, patient care practice, and patient outcomes. The primary outcome is use of neuromuscular monitoring in patients according to the type of muscle relaxant received. Secondary outcomes include last recorded train-of-four value, administration of reversal agents, and time to discharge from the postanesthesia care unit as well as a multiple-choice test to assess knowledge. The e-learning module was developed based on a needs assessment process, including focus group interviews, surveys, and expert opinions. The e-learning module was implemented in 6 anesthesia departments on 21 November 2016. Currently, we are collecting postintervention data. The final dataset will include data from more than 10,000 anesthesia procedures. We expect to publish the results in late 2017 or early 2018. With a dataset consisting of thousands of general anesthesia procedures, the INVERT study will assess whether an e-learning module can increase anesthetists' use of neuromuscular monitoring.

We have obtained visible and near-infrared reflectance spectra of asteroid (1951) Lick. According to its spectral characteristics in the visible region, this object has been classified as an A-type asteroid by Bus & Binzel (\\cite{bus2002b}). Here we present a mineralogical analysis of the reflectance spectrum obtained for this object. We compute several parameters that are extracted from the spectrum of the asteroid and that give relevant information about its mineralogical composition, using the method defined by Gaffey et al. (\\cite{gaffey1993}). We also present results obtained through the fit to the absorption band associated to the pressence of olivine using the Modified Gaussian Model (MGM) method developed by Sunshine et al. (\\cite{sunshi1990}). Our results indicate that (1951) Lick is an almost pure olivine. The composition of olivine on the surface of Lick is estimated to be about Fo90±10 (low-iron content). Based on observations made with the Nordic Optical Telescope, operated on the island of La Palma jointly by Denmark, Finland, Iceland, Norway, and Sweden, and on observations made with the Italian Telescopio Nazionale Galileo (TNG) operated on the island of La Palma by the Centro Galileo Galilei of the INAF (Instituto Nazionale di Astrofisica), both telescopes located at the Spanish ``Observatorio del Roque de los Muchachos'' of the Instituto de Astrofísica de Canarias.

The goals of this study were three-fold: to explore the reasons why some clinical teachers regularly attend centralised faculty development activities; to compare their responses with those of colleagues who do not attend, and to learn how we can make faculty development programmes more pertinent to teachers' needs. In 2008-2009, we conducted focus groups with 23 clinical teachers who had participated in faculty development activities on a regular basis in order to ascertain their perceptions of faculty development, reasons for participation, and perceived barriers against involvement. Thematic analysis and research team consensus guided the data interpretation. Reasons for regular participation included the perceptions that: faculty development enables personal and professional growth; learning and self-improvement are valued; workshop topics are viewed as relevant to teachers' needs; the opportunity to network with colleagues is appreciated, and initial positive experiences promote ongoing involvement. Barriers against participation mirrored those cited by non-attendees in an earlier study (e.g. volume of work, lack of time, logistical factors), but did not prevent participation. Suggestions for increasing participation included introducing a 'buddy system' for junior faculty members, an orientation workshop for new staff, and increased role-modelling and mentorship. The conceptualisation of faculty development as a means to achieve specific objectives and the desire for relevant programming that addresses current needs (i.e., expectancies), together with an appreciation of learning, self-improvement and networking with colleagues (i.e., values), were highlighted as reasons for participation by regular attendees. Medical educators should consider these 'lessons learned' in the design and delivery of faculty development offerings. They should also continue to explore the notion of faculty development as a social practice and the application of motivational theories that include expectancy-value constructs to personal and professional development.

Teaching, learning and assessment of medical ethics at the UK medical schools.

To evaluate the UK undergraduate medical ethics curricula against the Institute of Medical Ethics (IME) recommendations; to identify barriers to teaching and assessment of medical ethics and to evaluate perceptions of ethics faculties on the preparation of tomorrow's doctors for clinical practice. Questionnaire survey of the UK medical schools enquiring about content, structure and location of ethics teaching and learning; teaching and learning processes; assessment; influences over institutional approach to ethics education; barriers to teaching and assessment; perception of student engagement and perception of student preparation for clinical practice. The lead for medical ethics at each medical school was invited to participate (n=33). Completed responses were received from 11/33 schools (33%). 73% (n=8) teach all IME recommended topics within their programme. 64% (n=7) do not include ethics in clinical placement learning objectives. The most frequently cited barrier to teaching was lack of time (64%, n=7), and to assessment was lack of time and suitability of assessments (27%, n=3). All faculty felt students were prepared for clinical practice. IME recommendations are not followed in all cases, and ethics teaching is not universally well integrated into clinical placement. Barriers to assessment lead to inadequacies in this area, and there are few consequences for failing ethics assessments. As such, tomorrow's patients will be treated by doctors who are inadequately prepared for ethical decision making in clinical practice; this needs to be addressed by ethics leads with support from medical school authorities.

International nursing students and what impacts their clinical learning: literature review.

PubMed

Edgecombe, Kay; Jennings, Michele; Bowden, Margaret

2013-02-01

This paper reviews the sparse literature about international nursing students' clinical learning experiences, and also draws on the literature about international higher education students' learning experiences across disciplines as well as nursing students' experiences when undertaking international clinical placements. The paper aims to identify factors that may impact international nursing students' clinical learning with a view to initiating further research into these students' attributes and how to work with these to enhance the students' clinical learning. Issues commonly cited as affecting international students are socialisation, communication, culture, relationships, and unmet expectations and aspirations. International student attributes tend to be included by implication rather than as part of the literature's focus. The review concludes that recognition and valuing of international nursing students' attributes in academic and clinical contexts are needed to facilitate effective strategies to support their clinical practice in new environments.

A self-learning algorithm for biased molecular dynamics

PubMed Central

Tribello, Gareth A.; Ceriotti, Michele; Parrinello, Michele

2010-01-01

A new self-learning algorithm for accelerated dynamics, reconnaissance metadynamics, is proposed that is able to work with a very large number of collective coordinates. Acceleration of the dynamics is achieved by constructing a bias potential in terms of a patchwork of one-dimensional, locally valid collective coordinates. These collective coordinates are obtained from trajectory analyses so that they adapt to any new features encountered during the simulation. We show how this methodology can be used to enhance sampling in real chemical systems citing examples both from the physics of clusters and from the biological sciences. PMID:20876135

Where do youth learn about suicides on the Internet, and what influence does this have on suicidal ideation?

PubMed

Dunlop, Sally M; More, Eian; Romer, Daniel

2011-10-01

Young people are susceptible to suicidal behavior as a result of learning about the suicidal behavior of others. This study was designed to determine whether Internet sites, such as online news and social networking websites, expose young people to suicide stories that might increase suicide ideation. We reinterviewed 719 young people ages 14 to 24 who had participated in a prior nationally representative survey. Respondents reported knowledge of persons they knew who had committed or attempted suicide as well as personal experiences of hopelessness and suicidal ideation on both occasions. On the second occasion one year later, they also reported use of various Internet platforms and how often they had been exposed to suicide stories on those sites, as well as from personal sources. Changes in ideation as a function of exposure to different sources of suicide stories were analyzed holding constant prior hopelessness and ideation. While traditional sources of information about suicide were most often cited (79% were from friends and family or newspapers), online sources were also quite common (59%). Social networking sites were frequently cited as sources, but these reports were not linked to increases in ideation. However, online discussion forums were both cited as sources and associated with increases in ideation. The Internet and especially social networking sites are important sources of suicide stories. However, discussion forums appear to be particularly associated with increases in suicidal ideation. Greater efforts should be undertaken to promote Internet sites directed to young people that enhance effective coping with hopelessness and suicidal ideation. © 2011 The Authors.

Mapping the literature of case management nursing

PubMed Central

White, Pamela; Hall, Marilyn E.

2006-01-01

Objectives: Nursing case management provides a continuum of health care services for defined groups of patients. Its literature is multidisciplinary, emphasizing clinical specialties, case management methodology, and the health care system. This study is part of a project to map the literature of nursing, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association. The study identifies core journals cited in case management literature and indexing services that access those journals. Methods: Three source journals were identified based on established criteria, and cited references from each article published from 1997 to 1999 were analyzed. Results: Nearly two-thirds of the cited references were from journals; others were from books, monographs, reports, government documents, and the Internet. Cited journal references were ranked in descending order, and Bradford's Law of Scattering was applied. The many journals constituting the top two zones reflect the diversity of this field. Zone 1 included journals from nursing administration, case management, general medicine, medical specialties, and social work. Two databases, PubMed/MEDLINE and OCLC ArticleFirst, provided the best indexing coverage. Conclusion: Collections that support case management require a relatively small group of core journals. Students and health care professionals will need to search across disciplines to identify appropriate literature. PMID:16710470

DNA barcoding of Mobulid Ray Gill Rakers for Implementing CITES on Elasmobranch in China

Zeng, Yan; Wu, Zhongze; Zhang, Chunguang; Meng, Zhibin; Jiang, Zhigang; Zhang, Jie

2016-01-01

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has been counted on for conserving threatened marine fish since it regulates the commercial international trade of these species. Implementation of the international treaty for Mantas included on CITES Appendix II is challenging due to insufficient information on species identification and markets management. To fill the gap in such aspects, we identified five species of Mobulid rays (Mobula spps. and Manta spp) by using COI and NADH2 mtDNA markers in dried ray gill rakers from Chinese markets, namely, Mobula japonica (representing 54.8% of the sample set), M. tarapacana (14.4%), M. kuhlii (13.3%), M. thurstoni (6.4%), along with Manta birostris (11.2%; CITES Appendix II). The utilization and conservation statuses of these species were discussed. Based on combination of DNA barcodes and key morphological characters, we developed a three-step process for identifying the gill rakers of Mobulid rays which has been adopted by frontline enforcement in China. We hope that our work can serve as a foundation and basis to reinforce objectives of international treaties, regulation of consumer-driven markets, regional cooperation, and national fishery management on endangered elasmobranchs in China as well as related countries.

Serial killers with military experience: applying learning theory to serial murder.

PubMed

Castle, Tammy; Hensley, Christopher

2002-08-01

Scholars have endeavored to study the motivation and causality behind serial murder by researching biological, psychological, and sociological variables. Some of these studies have provided support for the relationship between these variables and serial murder. However, the study of serial murder continues to be an exploratory rather than explanatory research topic. This article examines the possible link between serial killers and military service. Citing previous research using social learning theory for the study of murder, this article explores how potential serial killers learn to reinforce violence, aggression, and murder in military boot camps. As with other variables considered in serial killer research, military experience alone cannot account for all cases of serial murder. Future research should continue to examine this possible link.

The use of city centre spaces by people with learning disability is not much debated in the literature. Here we include the thoughts and opinions of groups of people with learning disability as we undertook some guided walks through Sheffield city centre. We found that few of the participants had independent access to the city centre. Many cited concerns over personal safety and the most, on few occasions when they did visit, did so with family and/or paid staff for pre-planned purposes, usually linked to shopping. The need for appropriate support figured prominently. There is also a need to re-assess what we mean by social inclusion for this cohort. Copyright © 2014 Elsevier Ltd. All rights reserved.

A bibliometric analysis on top-cited articles in pain research.

PubMed

Chuang, Kun-Yang; Ho, Yuh-Shan

2014-05-01

The field of pain-related research has gained more attention as the prevalence of chronic pain increased over the years. The objective of this research was to identify highly cited papers, as well as contributors, to pain-related research. Pain-related articles published from 1900 to 2011 were screened, and highly cited papers, with at least 100 citations since publication, were identified and selected for a bibliometric analysis. The total number of papers, authorship, and collaboration statistics are presented for countries, institutions, and authors. To assess contributions, a new indicator, the major contributor index (MCI), was used. Citation trends for all papers, as well as for top papers, are presented. A total of 7,327 articles, 2.4% of all pain related articles, had received at least 100 citations since publication. In recent decades, top-cited articles have reached a citation peak more quickly, and have shown a more-rapid decreasing trend, compared with top-cited articles from earlier decades. The leading countries were United States, U.K., Canada, and Germany. The leading institutions were Harvard University, University of California, San Francisco, University of Texas, and University of Washington. MCI varied among leading institutions, as well as among individual authors. An indicator like the MCI can provide a proxy for the contributions made by an individual or institution. It reflects the independent research ability and leadership. In future evaluations of institution or individual performances, the MCI should be included, together with the number of total papers, to provide a better profile of research performance.

Fifty years of hemodialysis access literature: The fifty most cited publications in the medical literature.

PubMed

Skripochnik, Edvard; O'Connor, David J; Trestman, Eric B; Lipsitz, Evan C; Scher, Larry A

2018-02-01

Objectives The modern era of hemodialysis access surgery began with the publication in 1966 by Brescia et al. describing the use of a surgically created arteriovenous fistula. Since then, the number of patients on chronic hemodialysis and the number of publications dealing with hemodialysis access have steadily increased. We have chronicled the increase in publications in the medical literature dealing with hemodialysis access by evaluating the characteristics of the 50 most cited articles. Methods We queried the Science Citation Index from the years 1960-2014. Articles were selected based on a subject search and were ranked according to the number of times they were cited in the medical literature. Results The 50 most frequently cited articles were selected for further analysis and the number of annual publications was tracked. The landmark publication by Dr Brescia et al. was unequivocally the most cited article dealing with hemodialysis access (1109 citations). The subject matter of the papers included AV fistula and graft (9), hemodialysis catheter (9), complications and outcomes (24), and other topics (8). Most articles were published in nephrology journals (33), with fewer in surgery (7), medicine (7), and radiology (3) journals. Of the 17 journals represented, Kidney International was the clear leader, publishing 18 articles. There has been an exponential rise in the frequency of publications regarding dialysis access with 42 of 50 analyzed papers being authored after 1990. Conclusion As the number of patients on hemodialysis has increased dramatically over the past five decades, there has been a commensurate increase in the overall number of publications related to hemodialysis access.

Statistician Credit for Collaboration Requires Extending the Number of Cited Authors in Research Publications.

PubMed

Goldsmith, Charles H; Jin, Yanglin; He, Feng; Thabane, Lehana

2018-05-21

Statisticians collaborate with colleagues to provide advice on research. Most journals shorten the cited author list to save space. Statisticians are short-changed when it comes to proper recognition in the citations of published papers. Some journals cite First 3 authors, et al., First 6 authors, et al., and a few First 30, et al. OBJECTIVE: To empirically assess the credits for statistician's input in studies as measured by the visibility of their names in the citation of published papers of their collaborative health research studies. Six statisticians from Canadian Universities let us use their CVs for this study. Two coders (YJ, FH) each scored 60 entries from 5 different CVs to estimate reliability. Kappa statistics and intra-class correlation coefficients (ICC) measured reliability. Kappa statistics varied from 0.89 to 1.00 and the ICCs from 0.99 to 1.00 suggesting that the coders were very reliable. Over the 6 authors, there was a total of 2238 articles. Author numbers varied from 1 to 53 with 3 of 6 having a maximum of less than or equal to 30; author medians varied from 4 to 7. Using the cut of less than or equal to 3 authors 46.5% (1040/2238) would cite the statistician; for 6 it was 80.0% (1790/2274) and for 30 was 99.9% (2235/2238). These data suggest that statisticians would be cited in journals almost always if the criterion of the first 30 authors was used more often. Copyright © 2018. Published by Elsevier Inc.

Use of a Machine-learning Method for Predicting Highly Cited Articles Within General Radiology Journals.

PubMed

Rosenkrantz, Andrew B; Doshi, Ankur M; Ginocchio, Luke A; Aphinyanaphongs, Yindalon

2016-12-01

This study aimed to assess the performance of a text classification machine-learning model in predicting highly cited articles within the recent radiological literature and to identify the model's most influential article features. We downloaded from PubMed the title, abstract, and medical subject heading terms for 10,065 articles published in 25 general radiology journals in 2012 and 2013. Three machine-learning models were applied to predict the top 10% of included articles in terms of the number of citations to the article in 2014 (reflecting the 2-year time window in conventional impact factor calculations). The model having the highest area under the curve was selected to derive a list of article features (words) predicting high citation volume, which was iteratively reduced to identify the smallest possible core feature list maintaining predictive power. Overall themes were qualitatively assigned to the core features. The regularized logistic regression (Bayesian binary regression) model had highest performance, achieving an area under the curve of 0.814 in predicting articles in the top 10% of citation volume. We reduced the initial 14,083 features to 210 features that maintain predictivity. These features corresponded with topics relating to various imaging techniques (eg, diffusion-weighted magnetic resonance imaging, hyperpolarized magnetic resonance imaging, dual-energy computed tomography, computed tomography reconstruction algorithms, tomosynthesis, elastography, and computer-aided diagnosis), particular pathologies (prostate cancer; thyroid nodules; hepatic adenoma, hepatocellular carcinoma, non-alcoholic fatty liver disease), and other topics (radiation dose, electroporation, education, general oncology, gadolinium, statistics). Machine learning can be successfully applied to create specific feature-based models for predicting articles likely to achieve high influence within the radiological literature.

Percentile Ranking and Citation Impact of a Large Cohort of NHLBI-funded Cardiovascular R01 Grants

PubMed Central

Danthi, Narasimhan; Wu, Colin O.; Shi, Peibei; Lauer, Michael

2014-01-01

Rationale Funding decisions for cardiovascular R01 grant applications at NHLBI largely hinge on percentile rankings. It is not known whether this approach enables the highest impact science. Objective To conduct an observational analysis of percentile rankings and bibliometric outcomes for a contemporary set of funded NHLBI cardiovascular R01 grants. Methods and results We identified 1492 investigator-initiated de novo R01 grant applications that were funded between 2001 and 2008, and followed their progress for linked publications and citations to those publications. Our co-primary endpoints were citations received per million dollars of funding, citations obtained within 2-years of publication, and 2-year citations for each grant’s maximally cited paper. In 7654 grant-years of funding that generated $3004 million of total NIH awards, the portfolio yielded 16,793 publications that appeared between 2001 and 2012 (median per grant 8, 25th and 75th percentiles 4 and 14, range 0 – 123), which received 2,224,255 citations (median per grant 1048, 25th and 75th percentiles 492 and 1,932, range 0 – 16,295). We found no association between percentile ranking and citation metrics; the absence of association persisted even after accounting for calendar time, grant duration, number of grants acknowledged per paper, number of authors per paper, early investigator status, human versus non-human focus, and institutional funding. An exploratory machine-learning analysis suggested that grants with the very best percentile rankings did yield more maximally cited papers. Conclusions In a large cohort of NHLBI-funded cardiovascular R01 grants, we were unable to find a monotonic association between better percentile ranking and higher scientific impact as assessed by citation metrics.

Background and objectives Abuse occurs in all workplaces, including the medical field. The aim of this study was to determine the prevalence of perceived abuse among medical students, the types of abuse experienced during medical training, the source of abuse, and the perceived barriers to reporting abuse. Method This cross-sectional survey was conducted between September 2013 and January 2014 among medical graduates of King Abdul Aziz University, Jeddah. The survey questionnaire was designed to gather information regarding the frequency with which participants perceived themselves to have experienced abuse, the type of abuse, the source of abuse, and the reasons for nonreporting of perceived abuse. Data were analyzed using the Statistical Package for the Social Sciences. Result Of the 186 students enrolled in this study, 169 (90.9%) reported perceiving some form of abuse during medical school training. Perceived abuse was most often verbal (86.6%), although academic abuse (73.1%), sex discrimination (38.7%), racial or ethnic discrimination (29.0%), physical abuse (18.8%), religious discrimination (15.1%), and sexual harassment (8.6%) were also reported. Professors were most often cited as the sources of perceived abuse, followed by associate professors, demonstrators (or assistant teaching staff), and assistant professors. The Internal Medicine Department was the most frequently cited department where students perceived themselves to have experienced abuse. Only 14.8% of the students reported the abuse to a third party. Conclusion The self-reported prevalence of medical student abuse at King Abdul Aziz University is high. A proper system for reporting abuse and for supporting victims of abuse should be set up, to promote a good learning environment. PMID:24904225

Our objective was evaluate the effectiveness and acceptability of 3 methods of instructor interaction during distance learning with prerecorded seminars in orthodontic residencies and continuing education. After residents at 3 schools (Sydney, Australia; Winnipeg, Manitoba, Canada; and Manchester, United Kingdom) viewed a recorded interactive seminar, they discussed its content with the seminar leader at a distance via video conferencing, audio-only interaction by telephone, and Internet chat with Net Meeting software (Microsoft, Bellevue, Wash). The residents then completed evaluations containing both closed- and open-ended questions. In addition, attendees at the Iranian Orthodontic Congress also viewed a recorded seminar, had questions answered via an interpreter in a video conference, and completed summary evaluations. Video conferencing received the highest ratings and was never cited as the least favorite method of interaction. Telephone interaction was a close second in mean scores, and Internet chat was a distant third. All residents stated that they would like to be taught through distance education again. However, the Iranian orthodontists were less enthusiastic. Distance learning based on observation of recorded seminars and follow-up interaction is an acceptable method of instruction that can allow residents and practicing orthodontists access to various materials and experts, and perhaps help to ease the strains of current faculty shortages. More data are needed to determine whether video conferencing is worth the additional cost and complexity over audio-only interaction.

2016-01-01

Evaluating the impact of a scholarly article is of great significance and has attracted great attentions. Although citation-based evaluation approaches have been widely used, these approaches face limitations e.g. in identifying anomalous citations patterns. This negligence would inevitably cause unfairness and inaccuracy to the article impact evaluation. In this study, in order to discover the anomalous citations and ensure the fairness and accuracy of research outcome evaluation, we investigate the citation relationships between articles using the following factors: collaboration times, the time span of collaboration, citing times and the time span of citing to weaken the relationship of Conflict of Interest (COI) in the citation network. Meanwhile, we study a special kind of COI, namely suspected COI relationship. Based on the COI relationship, we further bring forward the COIRank algorithm, an innovative scheme for accurately assessing the impact of an article. Our method distinguishes the citation strength, and utilizes PageRank and HITS algorithms to rank scholarly articles comprehensively. The experiments are conducted on the American Physical Society (APS) dataset. We find that about 80.88% articles contain contributed citations by co-authors in 26,366 articles and 75.55% articles among these articles are cited by the authors belonging to the same affiliation, indicating COI and suspected COI should not be ignored for evaluating impact of scientific papers objectively. Moreover, our experimental results demonstrate COIRank algorithm significantly outperforms the state-of-art solutions. The validity of our approach is verified by using the probability of Recommendation Intensity.

DataCite - Making data sets citable

NASA Astrophysics Data System (ADS)

Brase, J.

2013-12-01

The scientific and information communities have largely mastered the presentation of, and linkages between, text-based electronic information by assigning persistent identifiers to give scientific literature unique identities and accessibility. Knowledge, as published through scientific literature, is however often the last step in a process originating from scientific research data. Today scientists are using simulation, observational, and experimentation techniques that yield massive quantities of research data. These data are analysed, synthesised, interpreted, and the outcome of this process is generally published as a scientific article. Access to the original data as the foundation of knowledge has become an important issue throughout the world and different projects have started to find solutions. Global collaboration and scientific advances could be accelerated through broader access to scientific research data. In other words, data access could be revolutionized through the same technologies used to make textual literature accessible. The most obvious opportunity to broaden visibility of and access to research data is to integrate its access into the medium where it is most often cited: electronic textual information. Besides this opportunity, it is important, irrespective of where they are cited, for research data to have an internet identity. Since 2005, the German National Library of Science and Technology (TIB) has offered a successful Digital Object Identifier (DOI) registration service for persistent identification of research data. Since 2010 these services are offered by the global consortium DataCite, carried by 17 member organisations from 12 different countries: The German National Library of Science and Technology (TIB), the German National Library of Medicine (ZB MED), the German National Library of Economics (ZBW) and the German GESIS - Leibniz Institute for the Social Sciences. Additional European members are: The Library of the ETH Zürich in Switzerland, the Library of TU Delft, from the Netherlands, the L'Institut de l'Information Scientifique et Technique (INIST) from France, The technical Information Center of Denmark, The British Library, the Sedish National Data Service (SND), the Conferenza dei Rettori delle Università Italiane (CRUI) from Italy. North America is represented through: the California Digital Library, the Office of Scientific and Technical Information (OSTI), the Purdue University and the Canada Institute for Scientific and Technical Information (CISTI). Furthermore the Australian National Data Service (ANDS) and the National Research Council of Thailand (NRCT) are members. DataCite offers through its members DOI registration for data centers, currently over 2 million objects have been registered with a DOI name and are available through a central search portal at http://search.datacite.org . Based on the DOI registration DataCite offers a variety of services such as a detailed statistic portal of the number of DOI names registered and resolved (http://stats.datacite.org). In June 2012 DataCite and the STM association (http://www.stm-assoc.org) signed a joint statement to encourage publishers and data centers to link articles and underlying data (http://www.datacite.org/node/65 )

2016-08-01

OBJECTIVE Despite the growing neurosurgical literature, a subset of pioneering studies have significantly impacted the field of metastatic spine disease. The purpose of this study was to identify and analyze the 100 most frequently cited articles in the field. METHODS A keyword search using the Thomson Reuters Web of Science was conducted to identify articles relevant to the field of metastatic spine disease. The results were filtered based on title and abstract analysis to identify the 100 most cited articles. Statistical analysis was used to characterize journal frequency, past and current citations, citation distribution over time, and author frequency. RESULTS The total number of citations for the final 100 articles ranged from 74 to 1169. Articles selected for the final list were published between 1940 and 2009. The years in which the greatest numbers of top-100 studies were published were 1990 and 2005, and the greatest number of citations occurred in 2012. The majority of articles were published in the journals Spine (15), Cancer (11), and the Journal of Neurosurgery (9). Forty-four individuals were listed as authors on 2 articles, 9 were listed as authors on 3 articles, and 2 were listed as authors on 4 articles in the top 100 list. The most cited article was the work by Batson (1169 citations) that was published in 1940 and described the role of the vertebral veins in the spread of metastases. The second most cited article was Patchell's 2005 study (594 citations) discussing decompressive resection of spinal cord metastases. The third most cited article was the 1978 study by Gilbert that evaluated treatment of epidural spinal cord compression due to metastatic tumor (560 citations). CONCLUSIONS The field of metastatic spine disease has witnessed numerous milestones and so it is increasingly important to recognize studies that have influenced the field. In this bibliographic study the authors identified and analyzed the most influential articles in the field of metastatic spine disease.

2018-03-20

Bibliometric analyses by highest number of citations can help researchers and funding agencies in determining the most influential articles in a field. The main objective of this analysis was to identify the top 100 cited articles addressing radiation exposure from medical imaging and assess their characteristics. Relevant articles were extracted from the Scopus database after a systematic search by researchers using an iteratively defined Boolean search string. Subsequently, exclusion criteria were applied. A list of top 100 articles was prepared, and articles were ranked according to the citations they had received. No time restriction was applied. Descriptive statistics of the data were compiled. The top-cited articles were published from 1970-2013, with the most articles published in 2009 and 2010 (12 articles in each year). The citations ranged from 107-1888 with a median of 272. Manuscripts from our top-cited list originated from 20 different countries, with contributions made by 158 authors and 160 organizations. Eighty-eight percent of studies evaluated patient-related radiation exposure, 7% health care workers, and 5% both or were not specified. Thirty-two percent of studies examined adult populations, 14% pediatric, and 54% included both populations or did not specify. Seventy-two percent of studies were dedicated to Computed Tomography, 8% to radiography/fluoroscopy, 9% to interventional procedures, 4% to nuclear medicine, and 7% to a combination of 2 or more modalities. The top 100 cited articles in medical imaging related to radiation exposure are diverse, originating from many countries with numerous contributing authors. The most common topics covered involve CT and adult patients. The recent peak in the most-highly cited articles (2010) suggests that increased attention has been devoted to this field in recent years. Based on these results, it would appear that research on radiation exposure in medical imaging is poised to continue expanding. Copyright © 2018 Elsevier Inc. All rights reserved.

Folstein, Jonathan R; Gauthier, Isabel; Palmeri, Thomas J

2010-01-01

We investigated how mere exposure to complex objects with correlated or uncorrelated object features affects later category learning of new objects not seen during exposure. Correlations among pre-exposed object dimensions influenced later category learning. Unlike other published studies, the collection of pre-exposed objects provided no information regarding the categories to be learned, ruling out unsupervised or incidental category learning during pre-exposure. Instead, results are interpreted with respect to statistical learning mechanisms, providing one of the first demonstrations of how statistical learning can influence visual object learning.

Machine learning algorithms are generally developed in computer science or adjacent disciplines and find their way into chemical modeling by a process of diffusion. Though particular machine learning methods are popular in chemoinformatics and quantitative structure–activity relationships (QSAR), many others exist in the technical literature. This discussion is methods-based and focused on some algorithms that chemoinformatics researchers frequently use. It makes no claim to be exhaustive. We concentrate on methods for supervised learning, predicting the unknown property values of a test set of instances, usually molecules, based on the known values for a training set. Particularly relevant approaches include Artificial Neural Networks, Random Forest, Support Vector Machine, k-Nearest Neighbors and naïve Bayes classifiers. WIREs Comput Mol Sci 2014, 4:468–481.

The primary objective was to identify the most common reasons for intending to cut back on alcohol use, in emergency department (ED) and trauma patient populations. The secondary objective was to determine the association between reason to cut back on alcohol and education level. We conducted the study at a level one trauma center in California between 2008 and 2012. This was a retrospective analysis of data collected from computerized alcohol screening and intervention (CASI). We excluded patients who drank too little, and those whose scores were consistent with dependency (Alcohol Use Disorders Identification Test [AUDIT]>19). The CASI database includes the patient's age, gender, language, education level, an AUDIT score (1-40 scale), a readiness to change score (1-10), and the option to choose any of 10 "reasons to cut back" on their alcohol consumption. From 10,537 patients, 1,202 met criteria for the study (848 ED, 354 trauma). Overall, the most common reasons cited for cutting back on alcohol were "To avoid health problems" (68.5%), "To avoid getting a DUI" (43.6%), "It could save me money" (42.0%), and "To avoid situations where I could get hurt" (41.0%). Trauma patients cited the following reasons significantly more than ED patients: "To avoid situations where I could get hurt" (46.3% versus 38.8%, respectively), "So I can be in control of my behavior" (40.7% versus 32.2%), and "My partner or spouse wants me to stop" (20.1% versus 15.0%). Additionally, those patients who cited "To avoid health problems" reported 1.2 points higher than average (p<0.001) on the 10-point readiness to change scale. Those who have completed some college or an associate degree cited "To avoid health problems" less often than high school graduates (odds ratio [OR] 0.45), while they cited "To avoid situations where I could get hurt" (OR 2.5) and "To avoid being in a car crash caused by alcohol use" (OR 3.8) more often than high school graduates. Health, injury, finances, and legal issues remain top concerns for patients, while trauma patients specifically had proportionately more concerns with situations where they could get hurt.

2006-01-01

Objective: This article is part of a project for mapping the literature of nursing. The purpose is to identify the core journals in nurse-midwifery and to determine the extent to which these titles are covered by standard indexing sources. Methods: Cited references from two source journals were analyzed to discover the most frequently cited publications, including their format, age, and amount of dispersion, as well as the indexes that offer the most complete coverage. Results: A study of the literature of nurse-midwifery reveals that the field is diverse, including such topics as women's health, obstetrics, gynecology, and parent-child relations, in addition to the practice of nurse-midwifery itself. Journals were the most heavily cited format, and analysis revealed that ten journals provided one-third of all the references in the study. Conclusions: A combination of Science Citation Index and Social Sciences Citation Index or PubMed/MEDLINE provided the best overall coverage because of the field's reliance on medical journals. CINAHL had the most complete coverage for the nurse-midwifery journals as well as nursing journals in general. PMID:16710467

Belief beyond the evidence: using the proposed effect of breakfast on obesity to show 2 practices that distort scientific evidence1234

PubMed Central

Brown, Andrew W; Bohan Brown, Michelle M

2013-01-01

Background: Various intentional and unintentional factors influence beliefs beyond what scientific evidence justifies. Two such factors are research lacking probative value (RLPV) and biased research reporting (BRR). Objective: We investigated the prevalence of RLPV and BRR in research about the proposition that skipping breakfast causes weight gain, which is called the proposed effect of breakfast on obesity (PEBO) in this article. Design: Studies related to the PEBO were synthesized by using a cumulative meta-analysis. Abstracts from these studies were also rated for the improper use of causal language and biased interpretations. In separate analyses, articles that cited an observational study about the PEBO were rated for the inappropriate use of causal language, and articles that cited a randomized controlled trial (RCT) about the PEBO were rated for misleadingly citing the RCT. Results: The current body of scientific knowledge indicates that the PEBO is only presumed true. The observational literature on the PEBO has gratuitously established the association, but not the causal relation, between skipping breakfast and obesity (final cumulative meta-analysis P value <10−42), which is evidence of RLPV. Four examples of BRR are evident in the PEBO literature as follows: 1) biased interpretation of one's own results, 2) improper use of causal language in describing one's own results, 3) misleadingly citing others’ results, and 4) improper use of causal language in citing others’ work. Conclusions: The belief in the PEBO exceeds the strength of scientific evidence. The scientific record is distorted by RLPV and BRR. RLPV is a suboptimal use of collective scientific resources.

Endovascular interventions for intracranial aneurysms have evolved substantially over the past several decades. A citation rank list is used to measure the scientific and/or clinical impact of an article. Our objective was to identify and analyze the characteristics of the 100 most cited articles in the field of endovascular therapy for intracranial aneurysms. We performed a retrospective bibliometric analysis between July and August 2017. Articles were searched on the Science Citation Index Expanded database using Web of Science in order to identify the most cited articles in the endovascular therapy of intracranial aneurysms since 1945. Using selected key terms ('intracranial aneurysm', 'aneurysm', 'aneurysmal subarachnoid', 'endovascular', 'coiling', 'stent-assisted', 'balloon-assisted', 'flow-diversion') yielded a total of 16 314 articles. The top 100 articles were identified and analyzed to extract relevant information, including citation count, authorship, article type, subject matter, institution, country of origin, and year of publication. Citations for the top 100 articles ranged from 133 to 1832. All articles were cited an average of 27 times per year. There were 45 prospective studies, including 7 level-II randomized controlled trials. Most articles were published in the 2000s (n=53), and the majority constituted level III or level IV evidence.

With limited health care resources, bibliometric studies can help guide researchers and research funding agencies towards areas where reallocation or increase in research activity is warranted. Bibliometric analyses have been published in many specialties and sub-specialties but our literature search did not reveal a bibliometric analysis on Cardiovascular Magnetic Resonance (CMR). The main objective of the study was to identify the trends of the top 100 cited articles on CMR research. Web of Science (WOS) search was used to create a database of all English language scientific journals. This search was then cross-referenced with a similar search term query of Scopus® to identify articles that may have been missed on the initial search. Articles were ranked by citation count and screened by two independent reviewers. Citations for the top 100 articles ranged from 178 to 1925 with a median of 319.5. Only 17 articles were cited more than 500 times, and the vast majority (n = 72) were cited between 200-499 times. More than half of the articles (n = 52) were from the United States of America, and more than one quarter (n = 21) from the United Kingdom. More than four fifth (n = 86) of the articles were published between the time period 2000-2014 with only 1 article published before 1990. Circulation and Journal of the American College of Cardiology made up more than half (n = 62) of the list. We found 10 authors who had greater than 5 publications in the list. Our study provides an insight on the characteristics and quality of the most highly cited CMR literature, and a list of the most influential references related to CMR.

Design issues for a reinforcement-based self-learning fuzzy controller

NASA Technical Reports Server (NTRS)

Yen, John; Wang, Haojin; Dauherity, Walter

1993-01-01

Fuzzy logic controllers have some often cited advantages over conventional techniques such as PID control: easy implementation, its accommodation to natural language, the ability to cover wider range of operating conditions and others. One major obstacle that hinders its broader application is the lack of a systematic way to develop and modify its rules and as result the creation and modification of fuzzy rules often depends on try-error or pure experimentation. One of the proposed approaches to address this issue is self-learning fuzzy logic controllers (SFLC) that use reinforcement learning techniques to learn the desirability of states and to adjust the consequent part of fuzzy control rules accordingly. Due to the different dynamics of the controlled processes, the performance of self-learning fuzzy controller is highly contingent on the design. The design issue has not received sufficient attention. The issues related to the design of a SFLC for the application to chemical process are discussed and its performance is compared with that of PID and self-tuning fuzzy logic controller.

Study of the decay and recovery of orbiting artificial space objects

NASA Technical Reports Server (NTRS)

1976-01-01

The reentry of earth-orbiting space objects unconsumed in the atmosphere represents a potential hazard to populated areas of the earth. The Smithsonian Astrophysical Observatory has conducted a program called Moonwatch, whose purposes were to observe orbiting artificial satellites and reentries of space objects and, if possible, to recover and analyze reentered pieces. In addition, through observations of low-perigee objects, data obtained by Moonwatchers have been instrumental in defining some of the factors affecting satellite decay. The objectives of the program are presented, and the problems that enter into satellite-orbit and decay predictions are addressed. Moonwatchers contributed substantially to increasing an overall prediction capability, and some of the specific achievements over the 6-year period are cited.

Volunteering as a community mother--a pathway to lifelong learning.

PubMed

Molloy, Mary

2007-05-01

This paper describes a study that was undertaken to investigate the effects of participating in a community volunteering programme (the Community Mothers Programme) on volunteers (Community Mothers). The aim of the study was to investigate if volunteering in this programme acted as a pathway to lifelong learning; did the volunteers recognise the learning of new knowledge and/or skills, and did their participation in the programme trigger them to progress to further education in other settings? A self-administered questionnaire method was used for data collection: 115 questionnaires being distributed to volunteers, with a response rate of eighty-two (71 per cent). Findings show that the majority of the respondents cited the learning of new knowledge and/or skills as a result of their participation in the Community Mothers Programme. Learning appeared to stem from the various training and activities, suggesting an educational process within the volunteer setting. Findings also show that the majority of respondents had progressed to further education. In this instance, therefore, volunteering did appear to act as a pathway to lifelong learning.

2016-07-01

Citation analysis aims to quantify the importance and influence of a published article within its field. We performed a bibliometric analysis to determine the most highly cited articles within rhinoplasty and their impact on current practice. The 100 most-cited articles relating to rhinoplasty, between and inclusive of January 1864 to September 2015, were extracted from Web of Science in October 2015. Title, source journal, publication year, total citations, average citations/year, type of article, level of evidence, country of origin, main focus, use of outcome measures, incorporation into "Selected Readings in Plastic Surgery," and funding status were recorded. The total number of citations per article ranged from 61 to 276 (1.5-12.1 average citations per year). Surgical technique was the focus of 53% of articles, particularly those for reconstruction (75%). The United States produced 72% of articles compared with 8% from the United Kingdom. The top 100 articles were published within 20 journals; "Plastic and Reconstructive Surgeons" contributed the most articles (n = 57). None of the articles achieved level 1 or 2 of evidence (Oxford Centre for Evidence-Based Medicine levels of evidence, 2011), with most achieving level 4 evidence (n = 64). Case-series were the most popular methodology (n = 37). Few articles used validated outcome measures (n = 21). Twenty-nine percent were referenced in "selected readings." Eighty-nine percent were unfunded studies. These top 100 articles are used in current teaching material and underpin surgical decision making. Developing and using validated objective assessment tools will benefit surgeons, patients, and the greater scientific community in objectively evaluating techniques with the most favorable results.

Walker, Shawn; Breslin, Eamonn; Scamell, Mandie; Parker, Pam

2017-06-01

The safety of vaginal breech birth depends on the skill of the attendant. The objective of this review was to identify, synthesize, and report the findings of evaluated breech birth training strategies. A systematic search of the following on-line databases: Medline, CINAHL Plus, PsychINFO, EBM Reviews/Cochrane Library, EMBASE, Maternity and Infant Care, and Pubmed, using a structured search strategy. Studies were included in the review if they evaluated the efficacy of a breech birth training program or particular strategies, including obstetric emergency training evaluations that reported differentiated outcomes for breech. Out of 1040 original citings, 303 full-text articles were assessed for eligibility, and 17 methodologically diverse studies met the inclusion criteria. A data collection form was used to extract relevant information. Data were synthesized, using an evaluation levels framework, including reaction, learning (subjective and objective assessment), and behavioral change. No evaluations included clinical outcome data. Improvements in self-assessed skill and confidence were not associated with improvements in objective assessments or behavioral change. Inclusion of breech birth as part of an obstetric emergencies training package without support in practice was negatively associated with subsequent attendance at vaginal breech births. As a result of the heterogeneity of the studies available, and the lack of evidence concerning neonatal or maternal outcomes, no conclusive practice recommendations can be made. However, the studies reviewed suggest that vaginal breech birth training may be enhanced by reflection, repetition, and experienced clinical support in practice. Further evaluation studies should prioritize clinical outcome data. © 2017 Wiley Periodicals, Inc.

Yu, Peter Paul

2015-03-01

One of the most important benefits of health information technology is to assist the cognitive process of the human mind in the face of vast amounts of health data, limited time for decision making, and the complexity of the patient with cancer. Clinical decision support tools are frequently cited as a technologic solution to this problem, but to date useful clinical decision support systems (CDSS) have been limited in utility and implementation. This article describes three unique sources of health data that underlie fundamentally different types of knowledge bases which feed into CDSS. CDSS themselves comprise a variety of models which are discussed. The relationship of knowledge bases and CDSS to rapid learning health systems design is critical as CDSS are essential drivers of rapid learning in clinical care.

Spectral characterization of V-type asteroids: are all the basaltic objects coming from Vesta?

NASA Astrophysics Data System (ADS)

Ieva, S.; Fulvio, D.; Dotto, E.; Lazzaro, D.; Perna, D.; Strazzulla, G.; Fulchignoni, M.

In the last twenty-five years several small basaltic V-type asteroids have been identified all around the main belt. Most of them are members of the Vesta dynamical family, but an increasingly large number appear to have no link with it. The question that arises is whether all these basaltic objects do indeed come from Vesta. In the light of the Dawn mission, who visited Vesta in 2011-2012, recent works were dedicated to the observation of several new V-type asteroids and their comparison with laboratory data (Fulvio et al., \\cite{Fulvio2015}), and to a statistical analysis of the spectroscopic and mineralogical properties of the largest sample of V-types ever collected (Ieva et al., \\cite{Ieva2015}, with the objective to highlight similarities and differences among objects belonging and not belonging to the Vesta dynamical family. Laboratory experiments support the idea that V-type NEAs spectral properties could be due to a balance of space weathering and rejuvenation processes triggered by close encounters with terrestrial planets. Statistical analysis shows that although most of the V-type asteroids in the inner main belt do have a surface composition compatible with Vesta family members, this seem not to be the case for V-types in the middle and outer main belt. For these Middle and Outer V-types (MOVs), their sizes, spectral parameters and location far away from the Vesta dynamical region point to a different origin than Vesta.

2018-03-01

Acoustic neuroma is the most common extra-axial primary cerebellopontine angle tumor in adults. A plethora of studies have been published on acoustic neuroma, but none of the previous works have highlighted the most influential articles. Our objective was to perform a bibliometric analysis of the 50 most-cited articles on acoustic neuroma. We performed a title-specific search on the Scopus database using the following search terms: "acoustic neuroma," "vestibular schwannoma," and "cerebellopontine angle." We recorded the 50 most-cited articles and reviewed them. The 50 most-cited articles had an average of 175 citations per article. All articles were published between 1980 and 2006, with 1997 the most prolific year, when 7 articles were published. The journals Neurosurgery and Laryngoscope published 10 and 8 of these articles, respectively. The most common study categories were nonsurgical management (17/50) and surgical management (13/50). Studies were predominantly published by otolaryngologists (22/50) and neurosurgeons (14/50). Douglas Kondziolka was the author with the highest number of contributions, with 7 publications. The majority of the articles were produced in the United States (64%). Identifying articles on acoustic neuroma with the most impact provides an important overview of the historical development of treatment methods and publication trends related to this condition. A finalized, comprehensive list of the most important works represents an excellent tool that can serve as a guide for evidence-based clinical practice. Copyright © 2017 Elsevier Inc.

Disappearing act: decay of uniform resource locators in health care management journals

PubMed Central

Wagner, Cassie; Gebremichael, Meseret D.; Soltys, Michael J.

2009-01-01

Objectives: This study examines the problem of decay of uniform resource locators (URLs) in health care management journals and seeks to determine whether continued availability at a given URL relates to the date of publication, the type of resource, or the top-level URL domain. Methods: The authors determined the availability of web-based resources cited in articles published in five source journals from 2002 to 2004. The data were analyzed using correlation, chi-square, and descriptive statistics. Attempts were made to locate the unavailable resources. Results: After checking twice, 49.3% of the original 2,011 cited resources could not be located at the cited URL. The older the article, the more likely that URLs in the reference list of that article were inactive (r = −0.62, P<0.001, n = 1,968). There was no difference in availability across resource types (χ2 = 5.28, df = 2, P = 0.07, n = 1,786). Whether an URL was active varied by top-level domain (χ2 = 14.92, df = 4, P = 0.00, n = 1,786). Conclusions: URL decay is a serious problem in health care management journals. In addition to using website archiving tools like WebCite, publishers should require authors to both keep copies of Internet-based information they used and deposit copies of data with the publishers.

Mastroianni, Patrícia C; Noto, Ana Regina; Galduróz, José Carlos F

2008-06-01

According to the World Health Organization, medicinal drug promotion should be reliable, accurate, truthful, informative, balanced, up-to-date and capable of substantiation. The objective of the present study was to review psychoactive drug advertisements to physicians as for information consistency with the related references and accessibility of the cited references. Data was collected in the city of Araraquara, Southeastern Brazil, in 2005. There were collected and reviewed 152 drug advertisements, a total of 304 references. References were requested directly from pharmaceutical companies' customer services and searched in UNESP (Ibict, Athenas) and BIREME (SciELO, PubMed, free-access indexed journals) library network and CAPES journals. Advertisement statements were checked against references using content analysis. Of all references cited in the advertisements studied, 66.7% were accessed. Of 639 promotional statements identified, 346 (54%) were analyzed. The analysis showed that 67.7% of promotional statements in the advertisements were consistent with their references, while the remaining was either partially consistent or inconsistent. Of the material analyzed, an average 2.5 (1-28) references was cited per advertisement. In the text body, there were identified 639 pieces of information clearly associated with at least one cited reference (average 3.5 pieces of information per advertisement). The study results evidenced difficult access to the references. Messages on efficacy, safety and cost, among others, are not always supported by scientific studies. There is a need for regulation changes and effective monitoring of drug promotional materials.

Eysenbach, Gunther; Trudel, Mathieu

Scholars are increasingly citing electronic "web references" which are not preserved in libraries or full text archives. WebCite is a new standard for citing web references. To "webcite" a document involves archiving the cited Web page through www.webcitation.org and citing the WebCite permalink instead of (or in addition to) the unstable live Web page. This journal has amended its "instructions for authors" accordingly, asking authors to archive cited Web pages before submitting a manuscript. Almost 200 other journals are already using the system. We discuss the rationale for WebCite, its technology, and how scholars, editors, and publishers can benefit from the service. Citing scholars initiate an archiving process of all cited Web references, ideally before they submit a manuscript. Authors of online documents and websites which are expected to be cited by others can ensure that their work is permanently available by creating an archived copy using WebCite and providing the citation information including the WebCite link on their Web document(s). Editors should ask their authors to cache all cited Web addresses (Uniform Resource Locators, or URLs) "prospectively" before submitting their manuscripts to their journal. Editors and publishers should also instruct their copyeditors to cache cited Web material if the author has not done so already. Finally, WebCite can process publisher submitted "citing articles" (submitted for example as eXtensible Markup Language [XML] documents) to automatically archive all cited Web pages shortly before or on publication. Finally, WebCite can act as a focussed crawler, caching retrospectively references of already published articles. Copyright issues are addressed by honouring respective Internet standards (robot exclusion files, no-cache and no-archive tags). Long-term preservation is ensured by agreements with libraries and digital preservation organizations. The resulting WebCite Index may also have applications for research assessment exercises, being able to measure the impact of Web services and published Web documents through access and Web citation metrics.

An investigation into the factors that motivate teachers to implement inquiry in the science classroom

NASA Astrophysics Data System (ADS)

Robbins, Beth Schieber

Inquiry-based science teaching is an inductive approach to science instruction that originated in constructivist learning theory and requires students to be active participants in their own learning process. In an inquiry-based classroom, students actively construct their knowledge of science through hands-on, engaged practices and inquiry-based approaches. Inquiry-based teaching stands in contrast to more traditional forms of teaching that see students as empty vessels to be filled by the teacher with rote facts. Despite calls from the NSF, the NRC, and the AAAS for more inquiry-based approaches to teaching science, research has shown that many teachers still do not use inquiry-based approaches. Teachers have cited difficulties including lack of time, high-stakes testing, a shortage of materials, problems with school-wide logistics, rigid science curricula, student passivity, and lack of prerequisite skills. The objective of this mixed-methods study was to examine to what extent specific, identifiable personality traits contribute to the likelihood that a teacher will use inquiry in the science classroom, and what factors figure predominantly as teachers' reasons for implementing inquiry. The findings of the study showed that the null hypotheses were not rejected. However, reduced conscientiousness and increased openness may be significant in indicating why teachers use inquiry-based teaching methods and avenues for further research. In addition, the qualitative results aligned with previous findings that showed that lack of resources (e.g., time and money) and peer support act as powerful barriers to implementing inquiry-based teaching. Inquiry teachers are flexible, come to teaching as a second or third career, and their classrooms can be characterized as chaotic, fun, and conducive to learning through engagement. The study suggests changes in practice among administrators and teachers. With adjustments in methods and survey instruments, additional research could provide valuable insights and further recommendations. Overall, this study has yielded information that may lead to changes in both practice and thinking related to inquiry-based teaching and learning.

Gastroenterology training in Latin America

2011-01-01

Latin America is characterized by ethnic, geographical, cultural, and economic diversity; therefore, training in gastroenterology in the region must be considered in this context. The continent’s medical education is characterized by a lack of standards and the volume of research continues to be relatively small. There is a multiplicity of events in general gastroenterology and in sub-disciplines, both at regional and local levels, which ensure that many colleagues have access to information. Medical education programs must be based on a clinical vision and be considered in close contact with the patients. The programs should be properly supervised, appropriately defined, and evaluated on a regular basis. The disparity between the patients’ needs, the scarce resources available, and the pressures exerted by the health systems on doctors are frequent cited by those complaining of poor professionalism. Teaching development can play a critical role in ensuring the quality of teaching and learning in universities. Continuing professional development programs activities must be planned on the basis of the doctors’ needs, with clearly defined objectives and using proper learning methodologies designed for adults. They must be evaluated and accredited by a competent body, so that they may become the basis of a professional regulatory system. The specialty has made progress in the last decades, offering doctors various possibilities for professional development. The world gastroenterology organization has contributed to the speciality through three distinctive, but closely inter-related, programs: Training Centers, Train-the-Trainers, and Global Guidelines, in which Latin America is deeply involved.

The importance and prestige of a scientific journal is increasingly being judged by the number of times the articles it publishes are cited or referenced in articles published in other scientific journals. Citation counting is also used to assess the merits of individual scientists when academic promotion and tenure are decided. With the help of Thomson, Institute for Scientific Information (Thomson ISI) a citation database was created for six leading forensic science and legal medicine journals. This database was used to determine the most highly cited articles, authors, journals and the most prolific authors of articles in the forensic sciences. The forensic science and legal medicine journals evaluated were: Journal of Forensic Sciences (JFS), Forensic Science International (FSI), International Journal of Legal Medicine (IJLM), Medicine, Science and the Law (MSL), American Journal of Forensic Medicine and Pathology (AJFMP), and Science and Justice (S&J). The resulting forensics database contained 14,210 papers published between 1981 and 2003. This in-depth bibliometric analysis has identified the creme de la creme in forensic science and legal medicine in a quantitative and objective way by citation analysis with focus on articles, authors and journals.

[SOME CONSIDERATIONS ABOUT THE INTRINSIC VALUE OF THE IMPACT FACTOR OF SCIENTIFIC JOURNALS].

The reason of higher number of citations of some articles is discussed. Some considerations about the journals' impact factor, its merits and its pitfalls are also made. Scientific journals' impact factor, popularized by the Institute for Scientific Information, has become an objective parameter for authors' evaluation and also for institutions and other related circumstances. There is no reason for the impact factor's gap between some English journals and those written in other languages. English journals probably benefit of the "Mathew's effect", according to which eminent scientists are more rewarded by similar contributions than others less known. It is paradoxical that most of the major achievements of our age do not appear among the 100 most cited articles. There is no homogeneity among all the articles appearing in each scientific journal: half of the articles are cited ten times more than the other half. However, those articles cited 0 times are credited like the better ones. Each article should be evaluated by its own citations, which would be its impact factor; the authors should be evaluated by their H index. Copyright AULA MEDICA EDICIONES 2014.

ISOCAM observations of the Hubble Deep Field reduced with the PRETI method

NASA Astrophysics Data System (ADS)

Aussel, H.; Cesarsky, C. J.; Elbaz, D.; Starck, J. L.

1999-02-01

We have developed a new ISOCAM data reduction technique based on wavelet analysis, especially designed for the detection of faint sources in mid-infrared surveys. This method, the Pattern REcognition Technique for Isocam data (PRETI) has been used to reduce the observations of the Hubble Deep Field (HDF) and flanking fields with ISOCAM at 6.75 (LW2) and 15 mu m (LW3) (Rowan-Robinson et al. \\cite{RowanRobinson}). Simulations of ISOCAM data allow us to test the photometric accuracy and completeness of the reduction. According to these simulations, the PRETI source list is 95% complete in the 15 mu m band at 200 mu Jy and in the 6.75 mu m band at 65 mu Jy, using detection thresholds which minimize the number of false detections. We detect 49 objects in the ISO-HDF at high confidence secure level, 42 in the LW3 filter, 3 in the LW2 filter, and 4 in both filters. An additional, less secure, list of 100 sources is presented, of which 89 are detected at 15 mu m only, 7 at 6.75 mu m only and 4 in both filters. All ISO-HDF objects detected in the HDF itself have optical or infrared counterparts, except for one from the additional list. All except one of the radio sources detected in the field by Fomalont et al. (\\cite{Fomalont}) are detected with ISOCAM. Using a precise correction for the field of view distortion of ISOCAM allows us to separate blended sources. This, together with the fact that PRETI allows to correct data on the tail of cosmic rays glitches, lead us to produce deeper source lists than previous authors. Our list of bright sources agree with those of Désert et al. (\\cite{IAS}) in both filters, and with those of Goldschmidt et al. (\\cite{Goldschmidt}) in the LW3 filter, with systematic difference in photometry. Number counts derived from our results show an excess by a factor of 10 with respect to the prediction of a no evolution model (Franceschini \\cite{Franceschini98}) in the LW3 band. On the contrary, the number of sources in the LW2 band is compatible with the prediction of such a model, but with greater uncertainties, given the small number of detections.

Introduction The College of Medicine at our institution underwent a major curricular revision in order to develop a patient-centered context for learning. The admission process was revised to reflect this change, adopting a holistic review process, with the hope of attracting students who were particularly well suited to a patient-centered curriculum and learning culture. Methods Patients from a single practitioner, who were accustomed to working with medical students, were asked if they would like to select the next generation of physicians. The patient's experience included a brief didactic presentation related to the patient's diagnosis and treatment. This was followed by an informal session with the applicants and the physician, where they shared their story in a small group setting. They were encouraged to share their experiences with the healthcare system, both positive and negative. The goal was to allow applicants to glean the importance of the human aspects of disease in our institutional culture of learning. Results The response and experience were overwhelmingly positive for the patients who donated their time to participate and for our applicants. Follow-up surveys indicated that our applicants found the experience to be unique and positive. Many of the students who chose to attend our university cited the interview experience and learning culture as factors that influenced their choice of medical schools. In addition, the Liaison Committee on Medical Education cited the favorability of the admission process in their recent site visit. Discussion Now in its fifth year, we can say that the inclusion of patients as part of the interview day is feasible as part of our admission process. We continue to make changes and monitor our progress, and we have added several other faculty members and specialties in order to ensure the program is sustainable. PMID:27520404

Going, Going, Still There: Using the WebCite Service to Permanently Archive Cited Web Pages

PubMed Central

Trudel, Mathieu

2005-01-01

Scholars are increasingly citing electronic “web references” which are not preserved in libraries or full text archives. WebCite is a new standard for citing web references. To “webcite” a document involves archiving the cited Web page through www.webcitation.org and citing the WebCite permalink instead of (or in addition to) the unstable live Web page. This journal has amended its “instructions for authors” accordingly, asking authors to archive cited Web pages before submitting a manuscript. Almost 200 other journals are already using the system. We discuss the rationale for WebCite, its technology, and how scholars, editors, and publishers can benefit from the service. Citing scholars initiate an archiving process of all cited Web references, ideally before they submit a manuscript. Authors of online documents and websites which are expected to be cited by others can ensure that their work is permanently available by creating an archived copy using WebCite and providing the citation information including the WebCite link on their Web document(s). Editors should ask their authors to cache all cited Web addresses (Uniform Resource Locators, or URLs) “prospectively” before submitting their manuscripts to their journal. Editors and publishers should also instruct their copyeditors to cache cited Web material if the author has not done so already. Finally, WebCite can process publisher submitted “citing articles” (submitted for example as eXtensible Markup Language [XML] documents) to automatically archive all cited Web pages shortly before or on publication. Finally, WebCite can act as a focussed crawler, caching retrospectively references of already published articles. Copyright issues are addressed by honouring respective Internet standards (robot exclusion files, no-cache and no-archive tags). Long-term preservation is ensured by agreements with libraries and digital preservation organizations. The resulting WebCite Index may also have applications for research assessment exercises, being able to measure the impact of Web services and published Web documents through access and Web citation metrics.

Understanding Graduate Teaching Assistants as Tutorial Instructors

Scherr, Rachel E.; Elby, A.

2006-12-01

Physics graduate teaching assistants are essential to the implementation of many collaborative active-learning environments, including tutorials. However, many TAs have trouble teaching effectively in these formats. Anecdotal evidence suggests that the problems may include inappropriate models of physics students, unproductive theories of learning, lack of experience with modern pedagogical methods, and weaknesses in understanding basic physics topics. A new research project at the University of Maryland is investigating the specific nature of TAs' experience with reform instruction using in-depth studies of TAs in course preparation sessions, in the tutorial classroom, in a weekly teaching seminar, and in reflective interviews. We find that all TAs studied recognize the insufficiency of traditional instruction to at least some extent, citing as evidence their own learning experiences, prior teaching experiences, and exposure to FCI-type data. We also observe great variability in views of the nature of physics knowledge and learning (both professed and enacted). These results are informing the development of the professional development program for physics teaching assistants at the University of Maryland.

Exploring the trends in surgical education research offers insight into concerns, developments, and questions researchers are exploring that are relevant to teaching and learning in surgical specialties. We conducted a review of the surgical education literature published between 2002 and 2012. The purpose was 2-fold: to provide an overview of the most frequently cited articles in the field of surgical education during the last decade and to describe the study designs and themes featured in these articles. Articles were identified through Web of Science by using "surgical education" and "English language" as search terms. Using a feature in Web of Science, we tracked the number of citations of any publication. Of the 800 articles produced by the initial search, we initially selected 23 articles with 45 or more citations, and ultimately chose the 20 articles that were most frequently cited for our analysis. Analysis of the most frequently cited articles published in US journals between the years 2002-2012 identified 7 research themes and presented them in order of frequency with which they appear: use of simulation, issues in student/resident assessment, specialty choice, patient safety, team training, clinical competence assessment, and teaching the clinical sciences, with surgical simulation being the central theme. Researchers primarily used descriptive methods. Popular themes in surgical education research illuminate the information needs of surgical educators as well as topics of high interest to the surgical community.

Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

Design issues of a reinforcement-based self-learning fuzzy controller for petrochemical process control

NASA Technical Reports Server (NTRS)

Yen, John; Wang, Haojin; Daugherity, Walter C.

1992-01-01

Fuzzy logic controllers have some often-cited advantages over conventional techniques such as PID control, including easier implementation, accommodation to natural language, and the ability to cover a wider range of operating conditions. One major obstacle that hinders the broader application of fuzzy logic controllers is the lack of a systematic way to develop and modify their rules; as a result the creation and modification of fuzzy rules often depends on trial and error or pure experimentation. One of the proposed approaches to address this issue is a self-learning fuzzy logic controller (SFLC) that uses reinforcement learning techniques to learn the desirability of states and to adjust the consequent part of its fuzzy control rules accordingly. Due to the different dynamics of the controlled processes, the performance of a self-learning fuzzy controller is highly contingent on its design. The design issue has not received sufficient attention. The issues related to the design of a SFLC for application to a petrochemical process are discussed, and its performance is compared with that of a PID and a self-tuning fuzzy logic controller.

Stamatescu, Victor; Wong, Sebastien; McDonnell, Mark D.; Kearney, David

2016-05-01

We investigate the application of learned convolutional filters in multi-object visual tracking. The filters were learned in both a supervised and unsupervised manner from image data using artificial neural networks. This work follows recent results in the field of machine learning that demonstrate the use learned filters for enhanced object detection and classification. Here we employ a track-before-detect approach to multi-object tracking, where tracking guides the detection process. The object detection provides a probabilistic input image calculated by selecting from features obtained using banks of generative or discriminative learned filters. We present a systematic evaluation of these convolutional filters using a real-world data set that examines their performance as generic object detectors.

In scientific writing, positive credits and negative criticisms can often be seen in the text mentioning the cited papers, providing useful information about whether a study can be reproduced or not. In this study, we focus on citation sentiment analysis, which aims to determine the sentiment polarity that the citation context carries towards the cited paper. A citation sentiment corpus was annotated first on clinical trial papers. The effectiveness of n-gram and sentiment lexicon features, and problem-specified structure features for citation sentiment analysis were then examined using the annotated corpus. The combined features from the word n-grams, the sentiment lexicons and the structure information achieved the highest Micro F-score of 0.860 and Macro-F score of 0.719, indicating that it is feasible to use machine learning methods for citation sentiment analysis in biomedical publications. A comprehensive comparison between citation sentiment analysis of clinical trial papers and other general domains were conducted, which additionally highlights the unique challenges within this domain.

Spatiotemporal information during unsupervised learning enhances viewpoint invariant object recognition

PubMed Central

Tian, Moqian; Grill-Spector, Kalanit

2015-01-01

Recognizing objects is difficult because it requires both linking views of an object that can be different and distinguishing objects with similar appearance. Interestingly, people can learn to recognize objects across views in an unsupervised way, without feedback, just from the natural viewing statistics. However, there is intense debate regarding what information during unsupervised learning is used to link among object views. Specifically, researchers argue whether temporal proximity, motion, or spatiotemporal continuity among object views during unsupervised learning is beneficial. Here, we untangled the role of each of these factors in unsupervised learning of novel three-dimensional (3-D) objects. We found that after unsupervised training with 24 object views spanning a 180° view space, participants showed significant improvement in their ability to recognize 3-D objects across rotation. Surprisingly, there was no advantage to unsupervised learning with spatiotemporal continuity or motion information than training with temporal proximity. However, we discovered that when participants were trained with just a third of the views spanning the same view space, unsupervised learning via spatiotemporal continuity yielded significantly better recognition performance on novel views than learning via temporal proximity. These results suggest that while it is possible to obtain view-invariant recognition just from observing many views of an object presented in temporal proximity, spatiotemporal information enhances performance by producing representations with broader view tuning than learning via temporal association. Our findings have important implications for theories of object recognition and for the development of computational algorithms that learn from examples. PMID:26024454

Features and uses of high-fidelity medical simulations that lead to effective learning: a BEME systematic review.

2005-01-01

1969 to 2003, 34 years. Simulations are now in widespread use in medical education and medical personnel evaluation. Outcomes research on the use and effectiveness of simulation technology in medical education is scattered, inconsistent and varies widely in methodological rigor and substantive focus. Review and synthesize existing evidence in educational science that addresses the question, 'What are the features and uses of high-fidelity medical simulations that lead to most effective learning?'. The search covered five literature databases (ERIC, MEDLINE, PsycINFO, Web of Science and Timelit) and employed 91 single search terms and concepts and their Boolean combinations. Hand searching, Internet searches and attention to the 'grey literature' were also used. The aim was to perform the most thorough literature search possible of peer-reviewed publications and reports in the unpublished literature that have been judged for academic quality. Four screening criteria were used to reduce the initial pool of 670 journal articles to a focused set of 109 studies: (a) elimination of review articles in favor of empirical studies; (b) use of a simulator as an educational assessment or intervention with learner outcomes measured quantitatively; (c) comparative research, either experimental or quasi-experimental; and (d) research that involves simulation as an educational intervention. Data were extracted systematically from the 109 eligible journal articles by independent coders. Each coder used a standardized data extraction protocol. Qualitative data synthesis and tabular presentation of research methods and outcomes were used. Heterogeneity of research designs, educational interventions, outcome measures and timeframe precluded data synthesis using meta-analysis. Coding accuracy for features of the journal articles is high. The extant quality of the published research is generally weak. The weight of the best available evidence suggests that high-fidelity medical simulations facilitate learning under the right conditions. These include the following: providing feedback--51 (47%) journal articles reported that educational feedback is the most important feature of simulation-based medical education; repetitive practice--43 (39%) journal articles identified repetitive practice as a key feature involving the use of high-fidelity simulations in medical education; curriculum integration--27 (25%) journal articles cited integration of simulation-based exercises into the standard medical school or postgraduate educational curriculum as an essential feature of their effective use; range of difficulty level--15 (14%) journal articles address the importance of the range of task difficulty level as an important variable in simulation-based medical education; multiple learning strategies--11 (10%) journal articles identified the adaptability of high-fidelity simulations to multiple learning strategies as an important factor in their educational effectiveness; capture clinical variation--11 (10%) journal articles cited simulators that capture a wide variety of clinical conditions as more useful than those with a narrow range; controlled environment--10 (9%) journal articles emphasized the importance of using high-fidelity simulations in a controlled environment where learners can make, detect and correct errors without adverse consequences; individualized learning--10 (9%) journal articles highlighted the importance of having reproducible, standardized educational experiences where learners are active participants, not passive bystanders; defined outcomes--seven (6%) journal articles cited the importance of having clearly stated goals with tangible outcome measures that will more likely lead to learners mastering skills; simulator validity--four (3%) journal articles provided evidence for the direct correlation of simulation validity with effective learning. While research in this field needs improvement in terms of rigor and quality, high-fidelity medical simulations are educationally effective and simulation-based education complements medical education in patient care settings.

Background Brief motivational interviewing (MI) can contribute to reductions in morbidity and mortality related to coronary artery disease, through health behavior change. Brief MI, unlike more intensive interventions, was proposed to meet the needs of clinicians with little spare time. While the provision of face-to-face brief MI training on a large scale is complicated, Web-based e-learning is promising because of the flexibility it offers. Objective The primary objective of this pilot study was to examine the feasibility and acceptability of a Web-based e-learning platform for brief MI (MOTIV@CŒUR), which was evaluated by nurses in cardiovascular care. The secondary objective was to assess the preliminary effect of the training on nurses’ perceived brief MI skills and self-reported clinical use of brief MI. Methods We conducted a single-group, pre-post pilot study involving nurses working in a coronary care unit to evaluate MOTIV@CŒUR, which is a Web-based e-learning platform for brief MI, consisting of two sessions lasting 30 and 20 minutes. MOTIV@CŒUR covers 4 real-life clinical situations through role-modeling videos showing nurse-client interactions. A brief introduction to MI is followed by role playing, during which a nurse practitioner evaluates clients’ motivation to change and intervenes according to the principles of brief MI. The clinical situations target smoking, medication adherence, physical activity, and diet. Nurses were asked to complete both Web-based training sessions asynchronously within 20 days, which allowed assessment of the feasibility of the intervention. Data regarding acceptability and preliminary effects (perceived skills in brief MI, and self-reported clinical use of conviction and confidence interventions) were self-assessed through Web-based questionnaires 30 days (±5 days) after the first session. Results We enrolled 27 women and 4 men (mean age 37, SD 9 years) in March 2016. Of the 31 participants, 24 (77%, 95% CI 63%–91%) completed both sessions in ≤20 days. At 30 days, 28 of the 31 participants (90%) had completed at least one session. The training was rated as highly acceptable, with the highest scores observed for information quality (mean 6.26, SD 0.60; scale 0–7), perceived ease of use (mean 6.16, SD 0.78; scale 0–7), and system quality (mean 6.15, SD 0.58; scale 0–7). Posttraining scores for self-reported clinical use of confidence interventions were higher than pretraining scores (mean 34.72, SD 6.29 vs mean 31.48, SD 6.75, respectively; P=.03; scale 10–50). Other results were nonsignificant. Conclusions Brief MI training using a Web-based e-learning platform including role-modeling videos is both feasible and acceptable according to cardiovascular care nurses. Further research is required to evaluate the e-learning platform in a randomized controlled trial.

2014-05-01

This paper presents the third study of research trends in science education. In this review, a total of 990 papers published in the International Journal of Science Education, the Journal of Research in Science Teaching, and Science Education from 2008 to 2012 were analyzed. The results indicate that in the recent five years (2008-2012), the top three research topics in the published papers were those regarding the context of students' learning, science teaching, and students' conceptual learning. The changes in the most popular research topics in the past 15 years also evidentially indicate shifts in the journals' preferences and researchers' interest. For example, in 2003-2007, context of students' learning replaced students' conceptual learning, which was the most published research topic from 1998 to 2002. The research topic of students' learning contexts continued to rank the first in 2008-2012. Moreover, there was an increasing trend of research papers regarding science teaching from 1998 to 2012. The analysis of highly cited papers revealed that research topics such as argumentation, inquiry-based learning, and scientific modeling were recently highlighted by science educators. In recent 15 years, productive researchers' publications also focused on the topics about context of students' learning, science teaching, and students' conceptual learning.

It is concluded that contrary to grammatical tradition, word order is not and cannot be completely free.…

The importance of metrics for evaluating scientific performance

NASA Astrophysics Data System (ADS)

Miyakawa, Tsuyoshi

Evaluation of scientific performance is a major factor that determines the behavior of both individual researchers and the academic institutes to which they belong. Because the number of researchers heavily outweighs the number of available research posts, and the competitive funding accounts for an ever-increasing proportion of research budget, some objective indicators of research performance have gained recognition for increasing transparency and openness. It is common practice to use metrics and indices to evaluate a researcher's performance or the quality of their grant applications. Such measures include the number of publications, the number of times these papers are cited and, more recently, the h-index, which measures the number of highly-cited papers the researcher has written. However, academic institutions and funding agencies in Japan have been rather slow to adopt such metrics. In this article, I will outline some of the currently available metrics, and discuss why we need to use such objective indicators of research performance more often in Japan. I will also discuss how to promote the use of metrics and what we should keep in mind when using them, as well as their potential impact on the research community in Japan.

Fear and reward learning can occur through direct experience or observation. Both channels can enhance survival or create maladaptive behavior. We used fMRI to isolate neural mechanisms of observational fear and reward learning and investigate whether neural response varied according to individual differences in neuroticism and extraversion. Participants learned object-emotion associations by observing a woman respond with fearful (or neutral) and happy (or neutral) facial expressions to novel objects. The amygdala-hippocampal complex was active when learning the object-fear association, and the hippocampus was active when learning the object-happy association. After learning, objects were presented alone; amygdala activity was greater for the fear (vs. neutral) and happy (vs. neutral) associated object. Importantly, greater amygdala-hippocampal activity during fear (vs. neutral) learning predicted better recognition of learned objects on a subsequent memory test. Furthermore, personality modulated neural mechanisms of learning. Neuroticism positively correlated with neural activity in the amygdala and hippocampus during fear (vs. neutral) learning. Low extraversion/high introversion was related to faster behavioral predictions of the fearful and neutral expressions during fear learning. In addition, low extraversion/high introversion was related to greater amygdala activity during happy (vs. neutral) learning, happy (vs. neutral) object recognition, and faster reaction times for predicting happy and neutral expressions during reward learning. These findings suggest that neuroticism is associated with an increased sensitivity in the neural mechanism for fear learning which leads to enhanced encoding of fear associations, and that low extraversion/high introversion is related to enhanced conditionability for both fear and reward learning.

View-invariant object category learning, recognition, and search: how spatial and object attention are coordinated using surface-based attentional shrouds.

Fazl, Arash; Grossberg, Stephen; Mingolla, Ennio

2009-02-01

How does the brain learn to recognize an object from multiple viewpoints while scanning a scene with eye movements? How does the brain avoid the problem of erroneously classifying parts of different objects together? How are attention and eye movements intelligently coordinated to facilitate object learning? A neural model provides a unified mechanistic explanation of how spatial and object attention work together to search a scene and learn what is in it. The ARTSCAN model predicts how an object's surface representation generates a form-fitting distribution of spatial attention, or "attentional shroud". All surface representations dynamically compete for spatial attention to form a shroud. The winning shroud persists during active scanning of the object. The shroud maintains sustained activity of an emerging view-invariant category representation while multiple view-specific category representations are learned and are linked through associative learning to the view-invariant object category. The shroud also helps to restrict scanning eye movements to salient features on the attended object. Object attention plays a role in controlling and stabilizing the learning of view-specific object categories. Spatial attention hereby coordinates the deployment of object attention during object category learning. Shroud collapse releases a reset signal that inhibits the active view-invariant category in the What cortical processing stream. Then a new shroud, corresponding to a different object, forms in the Where cortical processing stream, and search using attention shifts and eye movements continues to learn new objects throughout a scene. The model mechanistically clarifies basic properties of attention shifts (engage, move, disengage) and inhibition of return. It simulates human reaction time data about object-based spatial attention shifts, and learns with 98.1% accuracy and a compression of 430 on a letter database whose letters vary in size, position, and orientation. The model provides a powerful framework for unifying many data about spatial and object attention, and their interactions during perception, cognition, and action.

A problem-based learning strategy is used for curriculum planning and implementation at the Arabian Gulf University, Bahrain. Problems are constructed in a way that faculty-set objectives are expected to be identified by students during tutorials. Students in small groups, along with a tutor functioning as a facilitator, identify learning issues and define their learning objectives. We compared objectives identified by student groups with faculty-set objectives to determine extent of congruence, and identified factors that influenced students' ability at identifying faculty-set objectives. Male and female students were segregated and randomly grouped. A faculty tutor was allocated for each group. This study was based on 13 problems given to entry-level medical students. Pooled objectives of these problems were classified into four categories: structural, functional, clinical and psychosocial. Univariate analysis of variance was used for comparison, and a p > 0.05 was considered significant. The mean of overall objectives generated by the students was 54.2%, for each problem. Students identified psychosocial learning objectives more readily than structural ones. Female students identified more psychosocial objectives, whereas male students identified more of structural objectives. Tutor characteristics such as medical/non-medical background, and the years of teaching were correlated with categories of learning issues identified. Students identify part of the faculty-set learning objectives during tutorials with a faculty tutor acting as a facilitator. Students' gender influences types of learning issues identified. Content expertise of tutors does not influence identification of learning needs by students.

Since the first publication of learning objectives for the interdisciplinary subject "Rehabilitation, Physical Medicine, Naturopathic Treatment" in undergraduate medical education in 2004 a revision is reasonable due to heterogenous teaching programmes in the faculties and the introduction of the National Competence Based Catalogue of Learning Objectives in Medicine as well as the "Masterplan Medical Education 2020". Therefore the German Society of Rehabilitation Science and the German Society of Physical Medicine and Rehabilitation started a structured consensus process using the DELPHI-method to reduce the learning objectives and arrange them more clearly. Objectives of particular significance are emphasised. All learning objectives are assigned to the cognitive and methodological level 1 or to the action level 2. The learning objectives refer to the less detailed National Competence Based Catalogue of Learning Objectives in Medicine. The revised learning objectives will contribute to further progress in competence based and more homogenous medical teaching in core objectives of Rehabilitation, Physical Medicine, and Naturopathic Treatment in the faculties. © Georg Thieme Verlag KG Stuttgart · New York.

A bibliometric uses the citation count of an article to determine its impact on the clinical world. There is a paucity of literature concerning top article citations on spontaneous intracerebral hemorrhage (ICH). The main objective of this investigation was to bridge this gap and to provide understanding of the trends on the most influential articles written on this subject. The Scopus Library database was searched to determine the citations of all articles published on spontaneous ICH. Articles that focused on other forms of ICH, such as trauma-related hemorrhages, subarachnoid hemorrhages, or hemorrhages caused by anticoagulation, vascular malformations, or cavernomas, were excluded from our list. The articles were divided into 2 groups: "specific" articles, which focused specifically on spontaneous ICH, and "generalized" articles, which were about ICH in general, including spontaneous as well as other forms of ICH. We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. J. Broderick was the author with most publications in the list (n = 21). The largest subset of spontaneous ICH articles was published in the 5-year periods from 1996 to 2000 and 2001 to 2005 (n = 27 each). The United States had the highest number of articles (n = 49). The journal with the highest number of top 100 cited articles was Stroke, with 39, followed by Neurology with 16. Our study identifies the trends related to spontaneous ICH by analyzing the citation frequency of the most-cited articles in the field. Copyright © 2017 Elsevier Inc. All rights reserved.

Continuously Variable Rating: a new, simple and logical procedure to evaluate original scientific publications

2011-01-01

OBJECTIVE: Impact Factors (IF) are widely used surrogates to evaluate single articles, in spite of known shortcomings imposed by cite distribution skewness. We quantify this asymmetry and propose a simple computer-based procedure for evaluating individual articles. METHOD: (a) Analysis of symmetry. Journals clustered around nine Impact Factor points were selected from the medical “Subject Categories” in Journal Citation Reports 2010. Citable items published in 2008 were retrieved and ranked by granted citations over the Jan/2008 - Jun/2011 period. Frequency distribution of cites, normalized cumulative cites and absolute cites/decile were determined for each journal cluster. (b) Positive Predictive Value. Three arbitrarily established evaluation classes were generated: LOW (1.3≤IF<2.6); MID: (2.6≤IF<3.9); HIGH: (IF≥3.9). Positive Predictive Value for journal clusters within each class range was estimated. (c) Continuously Variable Rating. An alternative evaluation procedure is proposed to allow the rating of individually published articles in comparison to all articles published in the same journal within the same year of publication. The general guiding lines for the construction of a totally dedicated software program are delineated. RESULTS AND CONCLUSIONS: Skewness followed the Pareto Distribution for (1

Data Identifiers, Versioning, and Micro-citation

NASA Astrophysics Data System (ADS)

Parsons, M. A.; Duerr, R. E.

2012-12-01

Data citation, especially using Digital Object Identifiers (DOIs), is an increasingly accepted scientific practice. For example, the AGU Council asserts that data "publications" should "be credited and cited like the products of any other scientific activity," and Thomson Reuters has recently announced a data citation index built from DOIs assigned to data sets. Correspondingly, formal guidelines for how to cite a data set (using DOIs or similar identifiers/locators) have recently emerged, notably those from the international DataCite consortium, the UK Digital Curation Centre, and the US Federation of Earth Science Information Partners. These different data citation guidelines are largely congruent. They agree on the basic practice and elements of data citation, especially for relatively static, whole data collections. There is less agreement on some of the more subtle nuances of data citation. They define different methods for handling different data set versions, especially for the very dynamic, growing data sets that are common in Earth Sciences. They also differ in how people should cite specific, arbitrarily large elements, "passages," or subsets of a larger data collection, i.e., the precise data records actually used in a study. This detailed "micro-citation", and careful reference to exact versions of data are essential to ensure scientific reproducibility. Identifiers such as DOIs are necessary but not sufficient for the precise, detailed, references necessary. Careful practice must be coupled with the use of curated identifiers. In this paper we review the pros and cons of different approaches to versioning and micro-citation. We suggest a workable solution for most existing Earth science data and suggest a more rigorous path forward for the future.

Do scientific advancements lean on the shoulders of giants? A bibliometric investigation of the Ortega hypothesis.

2010-10-13

In contrast to Newton's well-known aphorism that he had been able "to see further only by standing on the shoulders of giants," one attributes to the Spanish philosopher Ortega y Gasset the hypothesis saying that top-level research cannot be successful without a mass of medium researchers on which the top rests comparable to an iceberg. The Ortega hypothesis predicts that highly-cited papers and medium-cited (or lowly-cited) papers would equally refer to papers with a medium impact. The Newton hypothesis would be supported if the top-level research more frequently cites previously highly-cited work than that medium-level research cites highly-cited work. Our analysis is based on (i) all articles and proceedings papers which were published in 2003 in the life sciences, health sciences, physical sciences, and social sciences, and (ii) all articles and proceeding papers which were cited within these publications. The results show that highly-cited work in all scientific fields more frequently cites previously highly-cited papers than that medium-cited work cites highly-cited work. We demonstrate that papers contributing to the scientific progress in a field lean to a larger extent on previously important contributions than papers contributing little. These findings support the Newton hypothesis and call into question the Ortega hypothesis (given our usage of citation counts as a proxy for impact).

Age-related impairments in active learning and strategic visual exploration.

PubMed

Brandstatt, Kelly L; Voss, Joel L

2014-01-01

Old age could impair memory by disrupting learning strategies used by younger individuals. We tested this possibility by manipulating the ability to use visual-exploration strategies during learning. Subjects controlled visual exploration during active learning, thus permitting the use of strategies, whereas strategies were limited during passive learning via predetermined exploration patterns. Performance on tests of object recognition and object-location recall was matched for younger and older subjects for objects studied passively, when learning strategies were restricted. Active learning improved object recognition similarly for younger and older subjects. However, active learning improved object-location recall for younger subjects, but not older subjects. Exploration patterns were used to identify a learning strategy involving repeat viewing. Older subjects used this strategy less frequently and it provided less memory benefit compared to younger subjects. In previous experiments, we linked hippocampal-prefrontal co-activation to improvements in object-location recall from active learning and to the exploration strategy. Collectively, these findings suggest that age-related memory problems result partly from impaired strategies during learning, potentially due to reduced hippocampal-prefrontal co-engagement.

Perceptual Learning and Attention: Reduction of Object Attention Limitations with Practice

PubMed Central

Dosher, Barbara Anne; Han, Songmei; Lu, Zhong-Lin

2012-01-01

Perceptual learning has widely been claimed to be attention driven; attention assists in choosing the relevant sensory information and attention may be necessary in many cases for learning. In this paper, we focus on the interaction of perceptual learning and attention – that perceptual learning can reduce or eliminate the limitations of attention, or, correspondingly, that perceptual learning depends on the attention condition. Object attention is a robust limit on performance. Two attributes of a single attended object may be reported without loss, while the same two attributes of different objects can exhibit a substantial dual-report deficit due to the sharing of attention between objects. The current experiments document that this fundamental dual-object report deficit can be reduced, or eliminated, through perceptual learning that is partially specific to retinal location. This suggests that alternative routes established by practice may reduce the competition between objects for processing resources. PMID:19796653

Quality of life for every one on the only home of mankind-TERRA shall be a feasibility only after realizing Space ecoliteracy amongst all stakeholders in space quest. Objectives of Informal Environmental Education(UNESCO/UNEP/IEEP,1977) mandates awareness, attitude, knowledge, skill and participation at Individual and Community domains. Application of Space Technology at both Telecommunications and Remote Sensing domain have started making the fact that mankind has a challenge to learn and affirm earthmanship. Community empowerment focus after Earth Summit 1992 mandate of Sustainable Development has demonstrated a deluge of best practices in Agriculture,Urban, Industries and service sectors all over the globe. Further, deployment of Space technologies have proved the immense potential only after pre-empting the participatory approach at individual and community levels.Indian Space Programme with its 44th year of space service to national development has demonstrated self reliance in space technology for human development. Space technology for the most underdeveloped is a success story both in communication and information tools for quality of life.

The traditional approach to the surgical clerkship has limitations, including variability of clinical exposure. To optimize student education we developed and introduced the core learning objectives curriculum, which is designed to allow students freedom to direct their learning and focus on core concepts. We performed a prospective, randomized, controlled study to compare the efficacy of core learning objectives vs traditional curricula through objective and subjective measures. Medical students were randomly assigned to the core learning objectives or traditional curricula during the 2-week urology clerkship. Faculty was blinded to student assignment. Upon rotation completion all students were given a 20-question multiple choice examination covering basic urology concepts. In addition, students completed a questionnaire addressing subjective clerkship satisfaction, comprising 15 questions. Between June 2005 and January 2007, 10 core learning objectives students and 10 traditional students completed the urology clerkship. The average +/- SEM multiple choice examination score was 12.1 +/- 0.87 and 9.8 +/- 0.59 for students assigned to the core learning objectives and traditional curricula, respectively (p <0.05). Subjective scores were higher in the core learning objectives cohort, although this result did not attain statistical significance (124.9 +/- 3.72 vs 114.3 +/- 4.96, p = 0.1). Core learning objectives students reported higher satisfaction in all 15 assessed subjective end points. Our experience suggests that the core learning objectives model may be an effective educational tool to help students achieve a broad and directed exposure to the core urological concepts.

Learned Non-Rigid Object Motion is a View-Invariant Cue to Recognizing Novel Objects

PubMed Central

Chuang, Lewis L.; Vuong, Quoc C.; Bülthoff, Heinrich H.

2012-01-01

There is evidence that observers use learned object motion to recognize objects. For instance, studies have shown that reversing the learned direction in which a rigid object rotated in depth impaired recognition accuracy. This motion reversal can be achieved by playing animation sequences of moving objects in reverse frame order. In the current study, we used this sequence-reversal manipulation to investigate whether observers encode the motion of dynamic objects in visual memory, and whether such dynamic representations are encoded in a way that is dependent on the viewing conditions. Participants first learned dynamic novel objects, presented as animation sequences. Following learning, they were then tested on their ability to recognize these learned objects when their animation sequence was shown in the same sequence order as during learning or in the reverse sequence order. In Experiment 1, we found that non-rigid motion contributed to recognition performance; that is, sequence-reversal decreased sensitivity across different tasks. In subsequent experiments, we tested the recognition of non-rigidly deforming (Experiment 2) and rigidly rotating (Experiment 3) objects across novel viewpoints. Recognition performance was affected by viewpoint changes for both experiments. Learned non-rigid motion continued to contribute to recognition performance and this benefit was the same across all viewpoint changes. By comparison, learned rigid motion did not contribute to recognition performance. These results suggest that non-rigid motion provides a source of information for recognizing dynamic objects, which is not affected by changes to viewpoint. PMID:22661939

2011-01-01

Purpose Wilms' tumors arise from arrested differentiation of renal progenitor cells. CITED1 is a transcriptional regulator that blocks the metanephric mesenchymal-to-epithelial conversion and is expressed in the blastema of both the developing kidney and Wilms' tumors. We hypothesized that alterations of CITED1-dependent signaling promote persistence of blastema and thereby subject these pluripotent cells to future oncogenic events. Methods We used a retroviral delivery system to overexpress the full-length CITED1 (F/L) protein and 2 deletion mutants lacking either of its known functional domains, ΔSID (Smad-4 Interacting Domain) and ΔCR2 (Conserved Region 2; the CITED1 transactivation domain), in a human Wilms' tumor cell line that endogenously expresses CITED1. In vitro effects on cellular proliferation and apoptosis were assayed. In vivo effects on tumorigenesis, growth, proliferation, and apoptosis were determined after heterotransplantation into immunodeficient mice (n = 15 per cell line). Results In vitro, overexpression of CITED1-F/L significantly increased, whereas overexpression of the functionally inactivating mutant, CITED1-ΔCR2, significantly reduced cellular proliferation relative to the other lines ( P <.0001). In vivo, Wilms' tumor incidence was significantly reduced in animals injected with cells overexpressing the mutant CITED1-ΔCR2 (7%) compared with CITED1-F/L (40%, P = .03) and CITED1-ΔSID (60%, P < .002). Similarly, mean tumor volume was least in the CITED1-ΔCR2 animals when compared with CITED1-F/L ( P = .03) and CITED1-ΔSID animals ( P <.005). Furthermore, the CITED1-ΔCR2 tumor showed the least cellular proliferation. Misexpression of CITED1 did not affect apoptosis either in vitro or in vivo. Conclusions Overexpression of CITED1 in a human Wilms' tumor cell line significantly increases proliferation in vitro, whereas mutation of its functionally critical transactivation domain (ΔCR2) significantly reduces proliferation. This mutation further perturbs tumorigenesis and tumor growth after heterotransplantation into immunodeficient mice. We speculate that overexpression of CITED1 promotes expansion of a rapidly proliferating population of blastema and thereby induces an unstable environment highly susceptible to future oncogenic events.

Learning to learn causal models.

PubMed

Kemp, Charles; Goodman, Noah D; Tenenbaum, Joshua B

2010-09-01

Learning to understand a single causal system can be an achievement, but humans must learn about multiple causal systems over the course of a lifetime. We present a hierarchical Bayesian framework that helps to explain how learning about several causal systems can accelerate learning about systems that are subsequently encountered. Given experience with a set of objects, our framework learns a causal model for each object and a causal schema that captures commonalities among these causal models. The schema organizes the objects into categories and specifies the causal powers and characteristic features of these categories and the characteristic causal interactions between categories. A schema of this kind allows causal models for subsequent objects to be rapidly learned, and we explore this accelerated learning in four experiments. Our results confirm that humans learn rapidly about the causal powers of novel objects, and we show that our framework accounts better for our data than alternative models of causal learning.

Conditional deletion of Apc in the murine intestine alters crypt-villus architecture and function. This process is accompanied by multiple changes in gene expression, including upregulation of Cited1, whose role in colorectal carcinogenesis is unknown. Here we explore the relevance of Cited1 to intestinal tumorigenesis. We crossed Cited1 null mice with ApcMin/+ and AhCre+Apcfl/fl mice and determined the impact of Cited1 deficiency on tumour growth/initiation including tumour multiplicity, cell proliferation, apoptosis and the transcriptome. We show that Cited1 is up-regulated in both human and murine tumours, and that constitutive deficiency of Cited1 increases survival in ApcMin/+ mice from 230.5 to 515 days. However, paradoxically, Cited1 deficiency accentuated nearly all aspects of the immediate phenotype 4 days after conditional deletion of Apc, including an increase in cell death and enhanced perturbation of differentiation, including of the stem cell compartment. Transcriptome analysis revealed multiple pathway changes, including p53, PI3K and Wnt. The activation of Wnt through Cited1 deficiency correlated with increased transcription of β-catenin and increased levels of dephosphorylated β-catenin. Hence, immediately following deletion of Apc, Cited1 normally restrains the Wnt pathway at the level of β-catenin. Thus deficiency of Cited1 leads to hyper-activation of Wnt signaling and an exaggerated Wnt phenotype including elevated cell death. Cited1 deficiency decreases intestinal tumourigenesis in ApcMin/+ mice and impacts upon a number of oncogenic signaling pathways, including Wnt. This restraint imposed by Cited1 is consistent with a requirement for Cited1 to constrain Wnt activity to a level commensurate with optimal adenoma formation and maintenance, and provides one mechanism for tumour repression in the absence of Cited1.

The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited articles may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997 to 2007. We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997 to 2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164 377 articles in 222 cardiovascular journals from 1997 to 2007. From 1997 to 2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2%, respectively. Of all the articles, 75 550 (46.0%) were poorly cited, of which 25 650 (15.6% overall) had no citations. From 1997 to 2007, the proportion of poorly cited articles declined slightly (52.1%-46.2%, trend P<0.001), although the absolute number of poorly cited articles increased by 2595 (trend P<0.001). At a journal level, 44% of cardiovascular journals had more than three-fourths of the journal's content poorly cited at 5 years. Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature and the number of poorly cited articles both increased substantially from 1997 to 2007. The high proportion of poorly cited articles and journals suggests inefficiencies in the cardiovascular research enterprise. © 2015 American Heart Association, Inc.

The objective of this study was to determine the value of using social media to communicate child health information to low-income parents. We evaluated qualitative data obtained through focus groups with low-income, predominantly Hispanic parents. Results were mixed; lack of time and credibility were the primary objections parents cited in using social media to obtain information about their children's health. Social media has value as part of an overall communication strategy, but more work is needed to determine the most effective way to use this channel in low-income populations.

Citation searches are more sensitive than keyword searches to identify studies using specific measurement instruments

Objective To compare the effectiveness of two search methods in identifying studies that used the Control Preferences Scale (CPS), a healthcare decision-making instrument commonly used in clinical settings. Study Design & Setting We searched the literature using two methods: 1) keyword searching using variations of “control preferences scale” and 2) cited reference searching using two seminal CPS publications. We searched three bibliographic databases [PubMed, Scopus, Web of Science (WOS)] and one full-text database (Google Scholar). We report precision and sensitivity as measures of effectiveness. Results Keyword searches in bibliographic databases yielded high average precision (90%), but low average sensitivity (16%). PubMed was the most precise, followed closely by Scopus and WOS. The Google Scholar keyword search had low precision (54%) but provided the highest sensitivity (70%). Cited reference searches in all databases yielded moderate sensitivity (45–54%), but precision ranged from 35–75% with Scopus being the most precise. Conclusion Cited reference searches were more sensitive than keyword searches, making it a more comprehensive strategy to identify all studies that use a particular instrument. Keyword searches provide a quick way of finding some but not all relevant articles. Goals, time and resources should dictate the combination of which methods and databases are used. PMID:25554521

To develop and implement formal learning objectives during a physical medicine and rehabilitation sports medicine rotation and characterize resident experiences with the objectives over a 16-mo period. Prospective, including learning objective development, implementation, and postrotation survey. A total of 69 learning objectives were developed by physical medicine and rehabilitation staff physician consensus, including 39 core objectives. Eighteen residents completed 4-wk sports medicine rotations from January 2003 through April 2004. Residents completed an average of 31 total objectives (45%; range, 3-52), of which 24 (62%; range, 3-35) were core. Residents completed the highest percentage of knee (60%), shoulder (57%), and ankle-foot (57%) objectives and reported that objectives related to these areas were most effective to facilitate learning. In general, residents reported that objective content was good and that the objectives delineated important concepts to learn during the rotation. Seventeen of 18 residents indicated that the objectives should be permanently implemented into the sports rotation and that similar objectives should be developed for other rotations. Based on our experience and the recommendations of residents, the average resident should be able to complete approximately 30 objectives during a typical 4-wk rotation. Successful implementation of specific, consensus-derived learning objectives is possible within the context of a busy clinical practice. Our initial physician staff and resident experience with the objectives suggests that this model may be useful as a supplementary educational tool in physical medicine and rehabilitation residency programs.

Objectives: To assess experts' perceptions of the contextual and local factors that promote or inhibit the implementation of waiting time management strategies (WTMS) in Canadian healthcare organizations. Methods: We conducted 16 semi-structured interviews and one focus group with individuals involved in WTMS at the federal, provincial or organizational level. Results: The most frequently cited local factor was physicians' participation. Physicians' leadership made the greatest difference in bringing resistant physicians on board. To be effective, however, local leadership had to be supported by senior management. Alignment of financial incentives between the contextual and local levels was also frequently cited, and interviewees stressed the importance of tools used to design, monitor, evaluate and prioritize WTMS. Conclusions: Finding the right balance between supportive resources and tools and an effective management system is a tough challenge. But achieving this balance will help reconcile contradictions between top-down and bottom-up WTMS. PMID:21286269

Good governance for nutrition in the Philippines: elements, experiences, and lessons learned.

PubMed

Solon, Florentino S

2006-12-01

Malnutrition is a multifactorial problem that needs a multisectoral solution. This article reviews the role of good governance in nutrition programs, citing the Philippines as an example. In the Philippines, these efforts are reflected in the partnership between the public and private sectors in the establishment of the country's capability in research, policy-making, and program implementation. The establishment of the different public institutions engaged in research and policy-making is discussed, highlighting the role of political will through legislation. The evolving tasks of the nutrition program are discussed by citing the tasks in two eras. In the 1970s, the challenges were limited national nutrition data, man-power, tools, and health infrastructure. The public and private institutions were able to respond by legislating national nutrition surveys and dedicated nutrition workers in each village. The challenges in the current era are improved implementation of health programs, given the devolution of health services, and the gathering of an evidence base to further strengthen and refine the strategies of supplementation, fortification, breastfeeding, and food security. In responding to these challenges, multisectoral solutions and collaboration are critical in providing an evidence base to formulate policy. The role of the private sector, with the Nutrition Center of the Philippines used as an example, is that of a supportive and collaborative partner in good governance. Finally, the lessons learned from the past decades of implementing a national nutrition program, given changes in political and economic circumstances, are summarized.

Competition between multiple words for a referent in cross-situational word learning

2016-01-01

Three experiments investigated competition between word-object pairings in a cross-situational word-learning paradigm. Adults were presented with One-Word pairings, where a single word labeled a single object, and Two-Word pairings, where two words labeled a single object. In addition to measuring learning of these two pairing types, we measured competition between words that refer to the same object. When the word-object co-occurrences were presented intermixed in training (Experiment 1), we found evidence for direct competition between words that label the same referent. Separating the two words for an object in time eliminated any evidence for this competition (Experiment 2). Experiment 3 demonstrated that adding a linguistic cue to the second label for a referent led to different competition effects between adults who self-reported different language learning histories, suggesting both distinctiveness and language learning history affect competition. Finally, in all experiments, competition effects were unrelated to participants’ explicit judgments of learning, suggesting that competition reflects the operating characteristics of implicit learning processes. Together, these results demonstrate that the role of competition between overlapping associations in statistical word-referent learning depends on time, the distinctiveness of word-object pairings, and language learning history.

Background Adaptive e-learning environments (AEEs) can provide tailored instruction by adapting content, navigation, presentation, multimedia, and tools to each user’s navigation behavior, individual objectives, knowledge, and preferences. AEEs can have various levels of complexity, ranging from systems using a simple adaptive functionality to systems using artificial intelligence. While AEEs are promising, their effectiveness for the education of health professionals and health professions students remains unclear. Objective The purpose of this systematic review is to assess the effectiveness of AEEs in improving knowledge, competence, and behavior in health professionals and students. Methods We will follow the Cochrane Collaboration and the Effective Practice and Organisation of Care (EPOC) Group guidelines on systematic review methodology. A systematic search of the literature will be conducted in 6 bibliographic databases (CINAHL, EMBASE, ERIC, PsycINFO, PubMed, and Web of Science) using the concepts “adaptive e-learning environments,” “health professionals/students,” and “effects on knowledge/skills/behavior.” We will include randomized and nonrandomized controlled trials, in addition to controlled before-after, interrupted time series, and repeated measures studies published between 2005 and 2017. The title and the abstract of each study followed by a full-text assessment of potentially eligible studies will be independently screened by 2 review authors. Using the EPOC extraction form, 1 review author will conduct data extraction and a second author will validate the data extraction. The methodological quality of included studies will be independently assessed by 2 review authors using the EPOC risk of bias criteria. Included studies will be synthesized by a descriptive analysis. Where appropriate, data will be pooled using meta-analysis by applying the RevMan software version 5.1, considering the heterogeneity of studies. Results The review is in progress. We plan to submit the results in the beginning of 2018. Conclusions Providing tailored instruction to health professionals and students is a priority in order to optimize learning and clinical outcomes. This systematic review will synthesize the best available evidence regarding the effectiveness of AEEs in improving knowledge, competence, and behavior in health professionals and students. It will provide guidance to policy makers, hospital managers, and researchers in terms of AEE development, implementation, and evaluation in health care.

Learn, how to learn

Narayanan, M.

2002-12-01

Ernest L. Boyer, in his 1990 book, "Scholarship Reconsidered: Priorities of the Professorate" cites some ground breaking studies and offers a new paradigm that identifies the need to recognize the growing conversation about teaching, scholarship and research in the Universities. The use of `ACORN' model suggested by Hawkins and Winter to conquer and mastering change, may offer some helpful hints for the novice professor, whose primary objective might be to teach students to `learn how to learn'. Action : It is possible to effectively change things only when a teaching professor actually tries out a new idea. Communication : Changes are successful only when the new ideas effectively communicated and implemented. Ownership : Support for change is extremely important and is critical. Only strong commitment for accepting changes demonstrates genuine leadership. Reflection : Feedback helps towards thoughtful evaluation of the changes implemented. Only reflection can provide a tool for continuous improvement. Nurture : Implemented changes deliver results only when nurtured and promoted with necessary support systems, documentation and infrastructures. Inspired by the ACORN model, the author experimented on implementing certain principles of `Total Quality Management' in the classroom. The author believes that observing the following twenty principles would indeed help the student learners how to learn, on their own towards achieving the goal of `Lifelong Learning'. The author uses an acronym : QUOTES : Quality Underscored On Teaching Excellence Strategy, to describe his methods for improving classroom teacher-learner participation. 1. Break down all barriers. 2. Create consistency of purpose with a plan. 3. Adopt the new philosophy of quality. 4. Establish high Standards. 5. Establish Targets / Goals. 6. Reduce dependence on Lectures. 7. Employ Modern Methods. 8. Control the Process. 9. Organize to reach goals. 10. Prevention vs. Correction. 11. Periodic Improvements. 12. Maintain Momentum. 13. Feedback : Communication. 14. Fact - Based Decisions. 15. Exploit Opportunities. 16. Mobilization of Expertise. 17. Drive out Fear. 18. Recognition / Keep Score. 19. Identify Accomplishments. 20. Customer Focus / Results. In conclusion, the author believes that the ACORN model and the QUOTES model may offer some guidelines that would help and enable the instructor to motivate learners to learn on their own.

2017-10-17

It has been proposed that learning from movement errors involves a credit assignment problem: did I misestimate properties of the object or those of my body? For example, an overestimate of arm strength and an underestimate of the weight of a coffee cup can both lead to coffee spills. Though previous studies have found signs of simultaneous learning of the object and of the body during object manipulation, there is little behavioral evidence about their quantitative relation. Here we employed a novel weight-transportation task, in which participants lift the first cup filled with liquid while assessing their learning from errors. Specifically, we examined their transfer of learning when switching to a contralateral hand, the second identical cup, or switching both hands and cups. By comparing these transfer behaviors, we found that 25% of the learning was attributed to the object (simply because of the use of the same cup) and 58% of the learning was attributed to the body (simply because of the use of the same hand). The nervous system thus seems to partition the learning of object manipulation between the object and the body.

Predictable Locations Aid Early Object Name Learning

PubMed Central

Benitez, Viridiana L.; Smith, Linda B.

2012-01-01

Expectancy-based localized attention has been shown to promote the formation and retrieval of multisensory memories in adults. Three experiments show that these processes also characterize attention and learning in 16- to 18- month old infants and, moreover, that these processes may play a critical role in supporting early object name learning. The three experiments show that infants learn names for objects when those objects have predictable rather than varied locations, that infants who anticipate the location of named objects better learn those object names, and that infants integrate experiences that are separated in time but share a common location. Taken together, these results suggest that localized attention, cued attention, and spatial indexing are an inter-related set of processes in young children that aid in the early building of coherent object representations. The relevance of the experimental results and spatial attention for everyday word learning are discussed. PMID:22989872

Preceptors’ Self-Assessment of Their Ability to Perform the Learning Objectives of an Experiential Program

PubMed Central

2012-01-01

Objective. To evaluate preceptors’ perception of their ability to perform the Structured Practical Experiences in Pharmacy (SPEP) learning objectives through a self-assessment activity. Methods. A self-assessment instrument consisting of 28 learning objectives associated with clinic, community, and hospital pharmacy practice experiences were developed. Preceptors rated their performance ability for each of the learning objectives using a 3-point Likert scale. Results. Of the 116 preceptors, 89 (77%) completed the self-assessment survey instrument. The overall preceptor responses to the items on performance of the 28 SPEP learning objectives ranged from good to excellent. Years of experience, practice experience setting, and involvement as a SPEP or SPEP and PharmD preceptor had no influence on their self-reported capabilities. Conclusion. Most preceptors rated their ability to perform the learning objectives for the structured practical experiences in pharmacy as high. Competency areas requiring further preceptor development were identified. PMID:23193333

Knockdown of Cbp/P300-interacting transactivator with Glu/Asp-rich carboxy-terminal domain 2 inhibits cell division and increases apoptosis in gastric cancer.

Tang, Ze; He, Gan; Xu, Jie; Zhongfu, Li

2017-05-01

Cbp/P300-interacting transactivator with Glu/Asp-rich carboxy-terminal domain 2 (CITED2) is a pleiotropic protein associated with numerous cell functions, including transcription and differentiation. The role of CITED2 has been investigated in a number of malignancies; however, the roles of this protein in gastric cancers remain unclear. Therefore, we determined the role of CITED2 in gastric cancers. Gastric cancer cell lines (MKN74, MKN28, 7901, and AGS) were used to assess CITED2 transcript levels. Messenger RNA levels were determined using quantitative polymerase chain reaction. Lentiviral vectors containing CITED2 small interfering RNA were used to knockdown CITED2 expression. Cell proliferation was assessed with fluorescent imaging and 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide assays. Apoptosis and cell cycle stages were assessed through flow cytometry, and formation of colonies was determined using a fluorescent microscope. All cell lines tested in this study expressed CITED2. The cell line expressing the highest levels of CITED2 (MKN74) showed significant knockdown of endogenous CITED2 expression on lentiviral infection. Cell proliferation was shown to be lower in CITED2 knockdown MKN74 cells. G1/S-phase cell cycle arrest was observed on silencing of CITED2 in MKN74 cells. A significant increase in apoptosis was observed on CITED2 knock down in MKN74 cells, while colony forming ability was significantly inhibited after knock down of CITED2. CITED2 supports gastric cancer cell colony formation and proliferation while inhibiting apoptosis making it a potential gene therapy target for gastric cancer. Copyright © 2016 Elsevier Inc.

2016-10-01

The purpose of this study was to identify core journals and other types of literature cited in four major pediatric nursing journals and to characterize coverage of these resources in major bibliographic databases. The study was part of the "Mapping the Literature of Nursing Project" of the Medical Library Association's Nursing and Allied Health Resource Section. It updates a similar analysis published in 2006 and determines whether citation patterns have changed over time. Cited references from articles published in 4 pediatric nursing journals between 2011 and 2013 were collected. Cited journal titles were ranked according to number of times cited and analyzed according to Bradford's Law of Scattering and the 80/20 rule to identify the most frequently cited journals. Five databases were surveyed to assess the coverage of the most-often-cited journals. The most frequently cited non-journal sources were also identified. Journals were the most frequently cited sources, followed by books, government documents, Internet resources, and miscellaneous resources. Most cited sources were cited within ten years of their publication, which was particularly true for government documents and Internet resources. Scopus had complete coverage of the most frequently cited journals, whereas PubMed had nearly complete coverage. Compared with the 2006 study, the list of top-cited journals referenced by pediatric nursing researchers has remained relatively stable, but the number of cited journal titles has increased. Book citations have declined, and Internet and government document references have increased. These findings suggest that librarians should retain subscriptions to frequently cited journal titles, provide efficient document delivery of articles from infrequently used journals, de-emphasize but not eliminate books, and connect patrons with useful open-access Internet resources.

2018-04-01

Malaria remains a major burden on global health, with roughly 200 million cases worldwide and more than 400,000 deaths per year. Besides biomedical research and political efforts, modern information technology is playing a key role in many attempts at fighting the disease. One of the barriers toward a successful mortality reduction has been inadequate malaria diagnosis in particular. To improve diagnosis, image analysis software and machine learning methods have been used to quantify parasitemia in microscopic blood slides. This article gives an overview of these techniques and discusses the current developments in image analysis and machine learning for microscopic malaria diagnosis. We organize the different approaches published in the literature according to the techniques used for imaging, image preprocessing, parasite detection and cell segmentation, feature computation, and automatic cell classification. Readers will find the different techniques listed in tables, with the relevant articles cited next to them, for both thin and thick blood smear images. We also discussed the latest developments in sections devoted to deep learning and smartphone technology for future malaria diagnosis. Published by Elsevier Inc.

In March 2017, we used ISI Web of Science (v5.11, Thomas Reuter, Philadelphia, Pennsylvania, USA) to search for the following key word: "chordoma". Articles were searched from 1900 to 2017. Articles were ranked based on number of citations. The results were evaluated to determine articles most clinically relevant to the management of chordomas. The top 50 articles that met the search criteria were further characterized on the basis of: title, author, citation density, journal of publication, year (and decade) of publication, institution and country of origin and paper topic. A total of 1,043 articles matched the search criteria. The most influential 50 articles were cited 65 to 290 times. The articles were published between 1926 and 2012, and all articles were published in English. Thirty-three publications (66%) originated from the United States and seven (14%) from Italy. Cancer accounted for the most frequent (n=9) destination journal followed by Journal of Bone and Joint Surgery (n=4). A total of 41 institutions contributed to the top 50 articles. The most common article types were: clinical 44% (n=22), papers that combined clinical and pathology findings 18% (n=9) and basic science research 14% (n=7). The top 50 cited articles on chordomas are predominantly clinical papers, arising from the United States and most frequently published in Cancer and Journal of Bone and Joint Surgery .

Bibliometric analyses can help researchers and research funding agencies determine which areas of medicine need appropriate research attention. Citation classics of several specialties and subspecialties have been published; however, a literature search did not turn up any in the field of valvular heart disease (VHD). The main objective of this analysis was to overcome this paucity by identifying the top 100 cited articles in VHD and to assess their characteristics. We chose Scopus as our database, from where relevant articles were extracted after a thorough search by 2 independent researchers. A list of the top 100 cited articles was prepared, after which a detailed analysis of the list was conducted. The top-cited articles were published in the 63-year era starting from 1951, with the most articles published in the 10-year interval of 2001 to 2010. The citations of the articles ranged from 438 to 2,717 with a median of 609.5. Manuscripts from our top-cited list originated from 25 different countries. Most of the articles in the top 100 list were published in high-impact journals, with about a third of the articles published in Circulation (n = 27). Our study also reveals that the current focus of researchers in the field is on transcatheter aortic valve replacement, and therefore, funding in this area is likely to result in impactful studies. In conclusion, our study highlights the characteristics of high-impact articles in the field of VHD, and this information may be useful for investigators planning to conduct studies in this area of medicine in the future.

Berhidi, Anna; Margittai, Zsuzsa; Vasas, Lívia

2012-12-02

The first step in the process of acquisition of impact factor for a scientific journal is to get registered at Thomson Reuters Web of Science database. The aim of this article is to evaluate the content and structure of Orvosi Hetilap with regards to selection criteria of Thomson Reuters, in particular to objectives of citation analysis. Authors evaluated issues of Orvosi Hetilap published in 2011 and calculated the unofficial impact factor of the journal based on systematic search in various citation index databases. Number of citations, quality of citing journals and scientific output of the editorial board members were evaluated. Adherence to guidelines of international publishers was assessed, as well. Unofficial impact factor of Orvosi Hetilap has been continuously rising every year in the past decade (except for 2004 and 2010). The articles of Orvosi Hetilap are widely cited by international authors and high impact factor journals, too. Further, more than half the articles cited are open access. The most frequently cited categories are original and review articles as well as clinical studies. Orvosi Hetilap is a weekly published journal, which is covered by many international databases such as PubMed/Medline, Scopus, Embase, and BIOSIS Previews. As regards to the scientific output of the editorial board members, the truncated mean of the number of their publications was 497, citations 2446, independent citations 2014 and h-index 21. While Orvosi Hetilap fulfils many criteria for getting covered by Thomson Reuters, it is worthwhile to implement a method of online citation system in order to increase the number of citations. In addition, scientific publications of all editorial board members should be made easily accessible. Finally, publications of comparative studies by multiple authors are encouraged as well as papers containing epidemiological data analyses.

Learning the 3-D structure of objects from 2-D views depends on shape, not format

PubMed Central

Tian, Moqian; Yamins, Daniel; Grill-Spector, Kalanit

2016-01-01

Humans can learn to recognize new objects just from observing example views. However, it is unknown what structural information enables this learning. To address this question, we manipulated the amount of structural information given to subjects during unsupervised learning by varying the format of the trained views. We then tested how format affected participants' ability to discriminate similar objects across views that were rotated 90° apart. We found that, after training, participants' performance increased and generalized to new views in the same format. Surprisingly, the improvement was similar across line drawings, shape from shading, and shape from shading + stereo even though the latter two formats provide richer depth information compared to line drawings. In contrast, participants' improvement was significantly lower when training used silhouettes, suggesting that silhouettes do not have enough information to generate a robust 3-D structure. To test whether the learned object representations were format-specific or format-invariant, we examined if learning novel objects from example views transfers across formats. We found that learning objects from example line drawings transferred to shape from shading and vice versa. These results have important implications for theories of object recognition because they suggest that (a) learning the 3-D structure of objects does not require rich structural cues during training as long as shape information of internal and external features is provided and (b) learning generates shape-based object representations independent of the training format.

2016-01-01

During perceptual learning the visual representations in the brain are altered, but these changes' causal role has not yet been fully characterized. We used transcranial direct current stimulation (tDCS) to investigate the role of higher visual regions in lateral occipital cortex (LO) in perceptual learning with complex objects. We also investigated whether object learning is dependent on the relevance of the objects for the learning task. Participants were trained in two tasks: object recognition using a backward masking paradigm and an orientation judgment task. During both tasks, an object with a red line on top of it were presented in each trial. The crucial difference between both tasks was the relevance of the object: the object was relevant for the object recognition task, but not for the orientation judgment task. During training, half of the participants received anodal tDCS stimulation targeted at the lateral occipital cortex (LO). Afterwards, participants were tested on how well they recognized the trained objects, the irrelevant objects presented during the orientation judgment task and a set of completely new objects. Participants stimulated with tDCS during training showed larger improvements of performance compared to participants in the sham condition. No learning effect was found for the objects presented during the orientation judgment task. To conclude, this study suggests a causal role of LO in relevant object learning, but given the rather low spatial resolution of tDCS, more research on the specificity of this effect is needed. Further, mere exposure is not sufficient to train object recognition in our paradigm.

This study aimed to engage wide-ranging stakeholders and develop consensus learning objectives for undergraduate and postgraduate medical education. A UK-wide consultation garnered opinions of healthcare students, healthcare educators and other key stakeholders about environmental sustainability in medical education. The policy Delphi approach informed this study. Draft learning objectives were revised iteratively during three rounds of consultation: online questionnaire or telephone interview, face-to-face seminar and email consultation. Twelve draft learning objectives were developed based on review of relevant literature. In round one, 64 participants' median ratings of the learning objectives were 3.5 for relevance and 3.0 for feasibility on a Likert scale of one to four. Revisions were proposed, e.g. to highlight relevance to public health and professionalism. Thirty three participants attended round two. Conflicting opinions were explored. Added content areas included health benefits of sustainable behaviours. To enhance usability, restructuring provided three overarching learning objectives, each with subsidiary points. All participants from rounds one and two were contacted in round three, and no further edits were required. This is the first attempt to define consensus learning objectives for medical students about environmental sustainability. Allowing a wide range of stakeholders to comment on multiple iterations of the document stimulated their engagement with the issues raised and ownership of the resulting learning objectives.

CITED2 modulates estrogen receptor transcriptional activity in breast cancer cells

Highlights: •The effects of elevated CITED2 on ER function in breast cancer cells are examined. •CITED2 enhances cell growth in the absence of estrogen and presence of tamoxifen. •CITED2 functions as a transcriptional co-activator of ER in breast cancer cells. -- Abstract: Cbp/p300-interacting transactivator with Glu/Asp-rich carboxy-terminal domain 2 (CITED2) is a member of the CITED family of non-DNA binding transcriptional co-activators of the p300/CBP-mediated transcription complex. Previously, we identified CITED2 as being overexpressed in human breast tumors relative to normal mammary epithelium. Upon further investigation within the estrogen receptor (ER)-positive subset of these breast tumor samples, we found thatmore » CITED2 mRNA expression was elevated in those associated with poor survival. In light of this observation, we investigated the effect of elevated CITED2 levels on ER function. While ectopic overexpression of CITED2 in three ER-positive breast cancer cell lines (MCF-7, T47D, and CAMA-1) did not alter cell proliferation in complete media, growth was markedly enhanced in the absence of exogenous estrogen. Correspondingly, cells overexpressing CITED2 demonstrated reduced sensitivity to the growth inhibitory effects of the selective estrogen receptor modulator, 4-hydroxytamoxifen. Subsequent studies revealed that basal ER transcriptional activity was elevated in CITED2-overexpressing cells and was further increased upon the addition of estrogen. Similarly, basal and estrogen-induced expression of the ER-regulated genes trefoil factor 1 (TFF1) and progesterone receptor (PGR) was higher in cells overexpressing CITED2. Concordant with this observation, ChIP analysis revealed higher basal levels of CITED2 localized to the TFF-1 and PGR promoters in cells with ectopic overexpression of CITED2, and these levels were elevated further in response to estrogen stimulation. Taken together, these data indicate that CITED2 functions as a transcriptional co-activator of ER in breast cancer cells and that its increased expression in tumors may result in estrogen-independent ER activation, thereby reducing estrogen dependence and response to anti-estrogen therapy.« less

Background Electronic learning (e-learning) through mobile technology represents a novel way to teach emergent otorhinolaryngology-head and neck surgery (ORL-HNS) disorders to undergraduate medical students. Whether a cognitive style of education combined with learning modules can impact learning outcomes and satisfaction in millennial medical students is unknown. Objective The aim of this study was to assess the impact of cognitive styles and learning modules using mobile e-learning on knowledge gain, competence gain, and satisfaction for emergent ORL-HNS disorders. Methods This randomized controlled trial included 60 undergraduate medical students who were novices in ORL-HNS at an academic teaching hospital. The cognitive style of the participants was assessed using the group embedded figures test. The students were randomly assigned (1:1) to a novel interactive multimedia (IM) group and conventional Microsoft PowerPoint show (PPS) group matched by age, sex, and cognitive style. The content for the gamified IM module was derived from and corresponded to the textbook-based learning material of the PPS module (video lectures). The participants were unblinded and used fully automated courseware containing the IM or PPS module on a 7-inch tablet for 100 min. Knowledge and competence were assessed using multiple-choice questions and multimedia situation tests, respectively. Each participant also rated their global satisfaction. Results All of the participants (median age 23 years, range 22-26 years; 36 males and 24 females) received the intended intervention after randomization. Overall, the participants had significant gains in knowledge (median 50%, interquartile range [IQR]=17%-80%, P<.001) and competence (median 13%, IQR=0%-33%, P=.006). There were no significant differences in knowledge gain (40%, IQR=13%-76% vs 60%, IQR=20%-100%, P=.42) and competence gain (0%, IQR= −21% to 38% vs 25%, IQR=0%-33%, P=.16) between the IM and PPS groups. However, the IM group had a higher satisfaction score (8, IQR=6-9 vs 6, IQR=4-7, P=.01) compared with the PPS group. Using Friedman’s two-way nonparametric analysis of variance, cognitive styles (field-independent, field-intermediate, or field-dependent classification) and learning modules (IM or PPS) had significant effects on both knowledge gain (both adjusted P<.001) and satisfaction (both adjusted P<.001). Conclusions Mobile e-learning is an effective modality to improve knowledge of emergent ORL-HNS in millennial undergraduate medical students. Our findings suggest the necessity of developing various modules for undergraduate medical students with different cognitive styles.

2015-12-01

To describe the creation of a digital learning object for diagnostic reasoning in nursing applied to the integumentary system at a public university of Piaui. A methodological study applied to technological production based on the pedagogical framework of problem-based learning. The methodology for creating the learning object observed the stages of analysis, design, development, implementation and evaluation recommended for contextualized instructional design. The revised taxonomy of Bloom was used to list the educational goals. The four modules of the developed learning object were inserted into the educational platform Moodle. The theoretical assumptions allowed the design of an important online resource that promotes effective learning in the scope of nursing education. This study should add value to nursing teaching practices through the use of digital learning objects for teaching diagnostic reasoning applied to skin and skin appendages.

Parallax measurements of six brown dwarfs.

Manjavacas, E.; Goldman, B.; Reffert, S.; Henning, T.

Accurate parallax measurements allow us to determine physical properties of brown dwarfs, and help us to constrain evolutionary and atmospheric models and reveal unresolved binaries. We measured absolute trigonometric parallaxes and proper motions of six cool brown dwarfs using background galaxies to establish an absolute reference frame. The brown dwarfs in our sample have spectral types between T2.5 and T7.5. The observations were taken in the J-band with the Omega2000 camera at the 3.5 m telescope at CAHA during a time period of 27 months. We obtained absolute parallaxes for our 6 brown dwarfs with a precision between 3 and 6 mas. We compared our results with the study by \\cite{Dupuy} and with the evolutionary models of \\cite{Allard}. For four of the six targets we found a good agreement in luminosity among objects of similar spectral types. The object 2MASS J11061197+2754225 is more than 1 mag overluminous in all bands pointing to binarity or higher order multiplicity. Based on observations taken with Omega-2000 at the 3.5 m telescope at the Centro Astronómico Hispano Alemán (CAHA) at Calar Alto, operated by the Max Planck Institut für Astronomie and the Instituto de Astrofísica de Andalucía (CSIC).

2015-04-01

Proper attribution for scientific source data is important in promoting transparency and recognising the role of data providers in science. Data sets such as those produced by seismic networks now need to be citable and permanently locatable for research users. Recently the EIDA and IRIS-DMC communities have worked together on development of methods for generation, maintenance and promotion of persistent identifiers for seismic networks. This resulted in a 2014 Recommendation by the International Federation of Digital Seismograph Networks (FDSN) on the use of Digital Object Identifiers (DOI) for seismic networks. These can be cited equivalently to scientific papers, and tools such as DataCite allow the tracking of citations to these datasets. The GEOFON, IRIS and RESIF data centres have now begun to roll-out of these seismic network DOIs. This has involved working with principal investigators to prepare metadata consistent with the FDSN recommendation, preparation of landing pages, and changes to the web sites to promote DOIs where available. This has involved preparing improved descriptions of the data (metadata) and clarifying how individuals and institutions should best be recognised for their contributions to making the data available. We illustrate this process for a few representative networks. We will be in contact with additional network operators to help them establish DOIs for their networks in future.

Spatial and reversal learning in the Morris water maze are largely resistant to six hours of REM sleep deprivation following training

PubMed Central

Walsh, Christine M.; Booth, Victoria; Poe, Gina R.

2011-01-01

This first test of the role of REM (rapid eye movement) sleep in reversal spatial learning is also the first attempt to replicate a much cited pair of papers reporting that REM sleep deprivation impairs the consolidation of initial spatial learning in the Morris water maze. We hypothesized that REM sleep deprivation following training would impair both hippocampus-dependent spatial learning and learning a new target location within a familiar environment: reversal learning. A 6-d protocol was divided into the initial spatial learning phase (3.5 d) immediately followed by the reversal phase (2.5 d). During the 6 h following four or 12 training trials/day of initial or reversal learning phases, REM sleep was eliminated and non-REM sleep left intact using the multiple inverted flowerpot method. Contrary to our hypotheses, REM sleep deprivation during four or 12 trials/day of initial spatial or reversal learning did not affect training performance. However, some probe trial measures indicated REM sleep-deprivation–associated impairment in initial spatial learning with four trials/day and enhancement of subsequent reversal learning. In naive animals, REM sleep deprivation during normal initial spatial learning was followed by a lack of preference for the subsequent reversal platform location during the probe. Our findings contradict reports that REM sleep is essential for spatial learning in the Morris water maze and newly reveal that short periods of REM sleep deprivation do not impair concurrent reversal learning. Effects on subsequent reversal learning are consistent with the idea that REM sleep serves the consolidation of incompletely learned items. PMID:21677190

How learning might strengthen existing visual object representations in human object-selective cortex.

Brants, Marijke; Bulthé, Jessica; Daniels, Nicky; Wagemans, Johan; Op de Beeck, Hans P

2016-02-15

Visual object perception is an important function in primates which can be fine-tuned by experience, even in adults. Which factors determine the regions and the neurons that are modified by learning is still unclear. Recently, it was proposed that the exact cortical focus and distribution of learning effects might depend upon the pre-learning mapping of relevant functional properties and how this mapping determines the informativeness of neural units for the stimuli and the task to be learned. From this hypothesis we would expect that visual experience would strengthen the pre-learning distributed functional map of the relevant distinctive object properties. Here we present a first test of this prediction in twelve human subjects who were trained in object categorization and differentiation, preceded and followed by a functional magnetic resonance imaging session. Specifically, training increased the distributed multi-voxel pattern information for trained object distinctions in object-selective cortex, resulting in a generalization from pre-training multi-voxel activity patterns to after-training activity patterns. Simulations show that the increased selectivity combined with the inter-session generalization is consistent with a training-induced strengthening of a pre-existing selectivity map. No training-related neural changes were detected in other regions. In sum, training to categorize or individuate objects strengthened pre-existing representations in human object-selective cortex, providing a first indication that the neuroanatomical distribution of learning effects depends upon the pre-learning mapping of visual object properties.

In addition, the results of cited by cole databases at home and abroad. The average value of IF and cited frequency of 13 kinds of ophthalmological periodicals were 0.3940 and 657 respectively in 2001 to 2006, which were higher than that of D part of CAJCCR. The periodicals which the five indexes of IF, non-self-citing impact factor, total cited frequency, the non-self-citing rate, immediacy index, rate of fund papers, web immediacy download rate, average value of h index and h(2)/n, high cited articles were Top 5 and cited by five or more than five kinds of the cole databases at home and abroad were Chinese Journal of Ophthalmology, Chinese Journal of Ocular Fundus Diseases, Practical Chinese Journal of Ophthalmology and Chinese Journal of Optometry & Ophthalmology. Most of indexes of Chinese Journal of Ophthalmology were the first. There are big difference between the 13 kinds of ophthalmological periodicals. The qualities of some ophthalmological periodicals should be improved.

What can alcohol researchers learn from research about the relationship between macro-level gender equality and violence against women?

PubMed

Roberts, Sarah C M

2011-01-01

This systematic review focuses on research about macro-level gender equality and violence against women (VAW) and identifies conceptually and theoretically driven hypotheses as well as lessons relevant for alcohol research. Hypotheses include: amelioration--increased equality decreases VAW; backlash--increased equality increases VAW; and convergence--increased equality reduces the gender gap; and hypotheses that distinguish between relative and absolute status, with relative status comparing men's and women's status and absolute status measuring women's status without regard to men. Systematic review of studies published through June 2009 identified through PubMed and Web of Science, as well as citing and cited articles. A total of 30 studies are included. Of 85 findings examining amelioration/backlash, 25% support amelioration, 22% backlash; and 53% are null. Of 13 findings examining convergence, 31% support and 23% are inconsistent with convergence; 46% are null. Neither the existence nor the direction of the equality and VAW relationship can be assumed. This suggests that the relationship between macro-level gender equality and alcohol should also not be assumed, but rather investigated through research.

Correcting a Longstanding Misconception about Social Roles and Personality: A Case Study in the Psychology of Science.

PubMed

Johnson, John A

2018-06-04

Psychologists often argue that sex roles direct different types of socializing behaviors toward males and females and that this differential treatment, in turn, leads to sex differences in personality. Widely cited in support of this thesis has been the Fels longitudinal study finding that dependency and passivity are stable from childhood to adulthood for females only and aggressiveness and sexuality for males only. The present article explains why the type of sex differences in personality stability cited by Fels researchers actually contradicts the view that sex role expectations cause these differences. The report suggests ways in which social learning theory, the dominant developmental paradigm of the 1960s, may have contributed to the misinterpretation of the Fels data and how the rise of social constructivism maintained this misinterpretation for decades. The article concludes by correcting misconceptions about biology and personality stability and by explaining why theories that incorporate biology are not only more adequate than social constructivism but also more effective in bringing about the changes in society that constructivists desire.

Learning Grasp Context Distinctions that Generalize

NASA Technical Reports Server (NTRS)

Platt, Robert; Grupen, Roderic A.; Fagg, Andrew H.

2006-01-01

Control-based approaches to grasp synthesis create grasping behavior by sequencing and combining control primitives. In the absence of any other structure, these approaches must evaluate a large number of feasible control sequences as a function of object shape, object pose, and task. This work explores a new approach to grasp synthesis that limits consideration to variations on a generalized localize-reach-grasp control policy. A new learning algorithm, known as schema structured learning, is used to learn which instantiations of the generalized policy are most likely to lead to a successful grasp in different problem contexts. Two experiments are described where Dexter, a bimanual upper torso, learns to select an appropriate grasp strategy as a function of object eccentricity and orientation. In addition, it is shown that grasp skills learned in this way can generalize to new objects. Results are presented showing that after learning how to grasp a small, representative set of objects, the robot's performance quantitatively improves for similar objects that it has not experienced before.

Transforming clinical imaging and 3D data for virtual reality learning objects: HTML5 and mobile devices implementation.

Trelease, Robert B; Nieder, Gary L

2013-01-01

Web deployable anatomical simulations or "virtual reality learning objects" can easily be produced with QuickTime VR software, but their use for online and mobile learning is being limited by the declining support for web browser plug-ins for personal computers and unavailability on popular mobile devices like Apple iPad and Android tablets. This article describes complementary methods for creating comparable, multiplatform VR learning objects in the new HTML5 standard format, circumventing platform-specific limitations imposed by the QuickTime VR multimedia file format. Multiple types or "dimensions" of anatomical information can be embedded in such learning objects, supporting different kinds of online learning applications, including interactive atlases, examination questions, and complex, multi-structure presentations. Such HTML5 VR learning objects are usable on new mobile devices that do not support QuickTime VR, as well as on personal computers. Furthermore, HTML5 VR learning objects can be embedded in "ebook" document files, supporting the development of new types of electronic textbooks on mobile devices that are increasingly popular and self-adopted for mobile learning. © 2012 American Association of Anatomists.

The company objects keep: Linking referents together during cross-situational word learning.

Learning the meanings of words involves not only linking individual words to referents but also building a network of connections among entities in the world, concepts, and words. Previous studies reveal that infants and adults track the statistical co-occurrence of labels and objects across multiple ambiguous training instances to learn words. However, it is less clear whether, given distributional or attentional cues, learners also encode associations amongst the novel objects. We investigated the consequences of two types of cues that highlighted object-object links in a cross-situational word learning task: distributional structure - how frequently the referents of novel words occurred together - and visual context - whether the referents were seen on matching backgrounds. Across three experiments, we found that in addition to learning novel words, adults formed connections between frequently co-occurring objects. These findings indicate that learners exploit statistical regularities to form multiple types of associations during word learning.

Cited2 (CBP/p300-interacting transactivator with glutamic acid (E)/aspartic acid (D)-rich tail 2) is a transcriptional modulator critical for the development of multiple organs. Although many Cited2-mediated phenotypes and molecular events have been well characterized using in vivo genetic murine models, Cited2-directed cell fate decision in embryonic stem cells (ESCs) remains elusive. In this study, we examined the role of Cited2 in the maintenance of stemness and pluripotency of murine ESCs by a gene-targeting approach. Cited2 knock-out (Cited2Δ/−, KO) ESCs display defective differentiation. Loss of Cited2 in differentiating ESCs results in delayed silencing of the genes involved in the maintenance of pluripotency and self-renewal of stem cells (Oct4, Klf4, Sox2, and c-Myc) and the disturbance in cardiomyocyte, hematopoietic, and neuronal differentiation. In addition, Cited2 KO ESCs experience a delayed induction of cardiomyocyte differentiation-associated proteins, NFAT3 (along with the reduced expression of NFAT3 target genes, Nkx2.5 and β-MHC), N-cadherin, and smooth muscle actin. CITED2 is recruited to the Oct4 promoter to regulate its expression during early ESC differentiation. This is the first demonstration that Cited2 controls ESC pluripotency and differentiation via direct regulation of Oct4 gene expression. PMID:22761414

Public audiences are often curious about planetary science. Scientists and education and public engagement specialists can leverage this interest to build scientific literacy. This poster will highlight research-based techniques the authors have tested with a variety of audiences, and are disseminating to planetary scientists through trainings.Techniques include:Make it personal. Audiences are interested in personal stories, which can capture the excitement, joy, and challenges that planetary scientists experience in their research. Audiences can learn more about the nature of science by meeting planetary scientists and hearing personal stories about their motivations, interests, and how they conduct research.Share relevant connections. Most audiences have very limited understanding of the solar system and the features and compositions of planetary bodies, but they enjoy learning about those objects they can see at night and factors that connect to their culture or local community.Demonstrate concepts. Some concepts can be clarified with analogies, but others can be demonstrated or modeled with materials. Demonstrations that are messy, loud, or that yield surprising results are particularly good at capturing an audience’s attention, but if they don’t directly relate to the key concept, they can serve as a distraction.Give them a role. Audience participation is an important engagement technique. In a presentation, scientists can invite the audience to respond to questions, pause to share their thoughts with a neighbor, or vote on an answer. Audiences can respond physically to prompts, raising hands, pointing, or clapping, or even moving to different locations in the room.Enable the audience to conduct an activity. People learn best by doing and by teaching others; simple hands-on activities in which the audience is discovering something themselves can be extremely effective at engaging audiences.This poster will cite examples of each technique, resources that can help planetary scientists develop presentations, demonstrations, and activities for public engagement events, and the research that supports the use of these techniques.

OBJECTIVE: To identify global research trends in the use of acupuncture to treat cerebral infarction. DATA RETRIEVAL: We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002–2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. SELECTION CRITERIA: Inclusion criteria: peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. Exclusion criteria: articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. MAIN OUTCOME MEASURES: (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. RESULTS: A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002–2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. CONCLUSION: In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars. PMID:25317148
