    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.

    To evaluate changes in the role of academics and the sources of funding for the medical research cited most frequently over the past decade. Database analysis. Web of Knowledge database. For each year from 1994 to 2003, articles in the domain of clinical medicine that had been cited most often by the end of 2004 were identified. Changes in authors' affiliations and funding sources were evaluated. Of the 289 frequently cited articles, most had at least one author with a university (76%) or hospital (57%) affiliation, and the proportion of articles with each type of affiliation was constant over time. Government or public funding was most common (60% of articles), followed by industry (36%). The proportion of most frequently cited articles funded by industry increased over time (odds ratio 1.17 per year, P = 0.001) and was equal to the proportion funded by government or public sources by 2001. 65 of the 77 most cited randomised controlled trials received funding from industry, and the proportion increased significantly over time (odds ratio 1.59 per year, P = 0.003). 18 of the 32 most cited trials published after 1999 were funded by industry alone. Academic affiliations remain prominent among the authors of the most frequently cited medical research. Such research is increasingly funded by industry, often exclusively so. Academics may be losing control of the clinical research agenda.

    We conducted an online survey of elementary school teachers in Washtenaw County, Michigan, regarding their confidence in their knowledge of epilepsy and their preferred media or sources of information about epilepsy. Eighty-three teachers (9.3%) responded. One quarter expressed a lack of confidence in their ability to teach students with epilepsy or to respond appropriately to a seizure. Teachers most frequently (68%) cited the Internet as their primary source of information about epilepsy, with the school nurse and parents/guardians also frequently mentioned (55% and 48%, respectively). In contrast, most respondents prefer that their information come from the school nurse (74%) or a physician (73%), while only 25% cited the Internet as a preferred source. Teachers most frequently indicated EpilepsyFoundation.org (70.5%) as a trusted source of information. Future collaborative education efforts between school nurses and physicians, especially through use of the Internet, could improve teachers' knowledge of epilepsy.

    This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field. Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford's Law of Scattering was applied to both sets to determine the most frequently cited journals. Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title. Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.

    The research provides an overview of the health care management literature and the indexing coverage of core journal literature. 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. 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. 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.

    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.

    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.

    Estimated medical costs ("T") and QALYs ("Q") associated with smoking are frequently used in cost-utility analyses of tobacco control interventions. The goal of this study was to understand how researchers have addressed the methodological challenges involved in estimating these parameters. Data were collected as part of a systematic review of tobacco modeling studies. We searched five electronic databases on July 1, 2013 with no date restrictions and synthesized studies qualitatively. Studies were eligible for the current analysis if they were U.S.-based, provided an estimate for Q, and used a societal perspective and lifetime analytic horizon to estimate T. We identified common methods and frequently cited sources used to obtain these estimates. Across all 18 studies included in this review, 50 % cited a 1992 source to estimate the medical costs associated with smoking and 56 % cited a 1996 study to derive the estimate for QALYs saved by quitting or preventing smoking. Approaches for estimating T varied dramatically among the studies included in this review. T was valued as a positive number, negative number and $0; five studies did not include estimates for T in their analyses. The most commonly cited source for Q based its estimate on the Health Utilities Index (HUI). Several papers also cited sources that based their estimates for Q on the Quality of Well-Being Scale and the EuroQol five dimensions questionnaire (EQ-5D). Current estimates of the lifetime medical care costs and the QALYs associated with smoking are dated and do not reflect the latest evidence on the health effects of smoking, nor the current costs and benefits of smoking cessation and prevention. Given these limitations, we recommend that researchers conducting economic evaluations of tobacco control interventions perform extensive sensitivity analyses around these parameter estimates.

    Abstract Aims: To identify and characterize the top-cited articles in the field of islet transplantation. Methods: We used the Science Citation Index Expanded database to identify the most frequently cited articles published after 1900. Articles were evaluated using the following characteristics: citation number, publication year, study design, references, country and institution of origin, authorship, and journal. Keyword analysis and citation networks were used to analyze research trends. Results: The most frequently cited articles received between 146 and 2988 citations; the median was 291. All of the most frequently cited articles were published between 1972 and 2012, and 85 articles were published after 1990. The most popular study design involved basic science (75 articles). The leading countries were the United States (US) and Canada, and the leading institutions were the University of Alberta, Canada, and the University of Minnesota, in the US. Journals specializing in diabetes or transplantation published more than half of the articles (n = 53, 52%), with the journal Diabetes publishing the largest number (n = 30). No association was found between a journal's impact factor and the number of top-cited articles it published. There was no correlation between the number of citations and the number of years since publication, authors, participating institutions, or countries involved. Top-cited articles focused on 2 themes: the use of antirejection immunotherapy or biocompatible encapsulations to prolong graft survival, and assessments of the efficacy of islet transplants, in particular, islet allografts. Conclusions: Our study can help researchers to identify and decipher the characteristics of top-cited articles in the field of islet transplantation. Just as clinically successful allografts are carried out using the Edmonton protocol, autografts and xenografts should be similarly strengthened to solve problems relating to immune rejection and islet sources, respectively.

    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. 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. 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. 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.

    Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed.

    To analyze the inherent quality of articles published in our journal enjoying high citation rate, and to explore strategies on improving impact of papers. Scientific papers published in Chinese Journal of Burns from February 2000 to December 2009, with citation rate equal to or higher than 20 times were collected for classification according to their publication year, publication form, subject distribution, regional and institutional distribution, frequency of authors appeared in those published papers, frequency of winning prizes, and sources of fund (national, ministerial, or provincial). Data were processed by Microsoft Excel software. Altogether 64 scientific papers with high citation rate were published from 2000 to 2006. Original articles and expert forum accounted for 55 (86.0%). Twenty-one articles of clinical study were cited frequently, among them one was cited for 79 times. Articles dealing with subjects with popular interest or cutting-edge problems were cited frequently. Most articles winning high citation rate were originated from institutions located in Chongqing, Beijing, Shanghai, and Xi'an, etc. Those scientific papers which were instructed by specialists, with high level foundation and won prizes were cited with high frequency. The top 20 articles were mainly cited by excellent doctoral dissertations and master theses originated from 11 institutions for higher education, and source journals of Chinese Scientific and Technical Papers and Citations Database. Authors should emphasize subject planning in order to compose papers with high quality. The editorial board should make arrangements with influential specialists with related skills for their contributions based on subjects of popular interest concerning the cutting-edge problems of the specific specialty, and pay close attention to papers on clinical study and those with funding from high levels, to improve impact of the articles.

    Introduction: This project is a collaborative effort of the Task Force on Mapping the Nursing Literature of the Nursing and Allied Health Resources Section of the Medical Library Association. This overview summarizes eighteen studies covering general nursing and sixteen specialties. Method: Following a common protocol, citations from source journals were analyzed for a three-year period within the years 1996 to 2000. Analysis included cited formats, age, and ranking of the frequency of cited journal titles. Highly cited journals were analyzed for coverage in twelve health sciences and academic databases. Results: Journals were the most frequently cited format, followed by books. More than 60% of the cited resources were published in the previous seven years. Bradford's law was validated, with a small core of cited journals accounting for a third of the citations. Medical and science databases provided the most comprehensive access for biomedical titles, while CINAHL and PubMed provided the best access for nursing journals. Discussion: Beyond a heavily cited core, nursing journal citations are widely dispersed among a variety of sources and disciplines, with corresponding access via a variety of bibliographic tools. Results underscore the interdisciplinary nature of the nursing profession. Conclusion: For comprehensive searches, nurses need to search multiple databases. Libraries need to provide access to databases beyond PubMed, including CINAHL and academic databases. Database vendors should improve their coverage of nursing, biomedical, and psychosocial titles identified in these studies. Additional research is needed to update these studies and analyze nursing specialties not covered. PMID:16636714

    To evaluate and compare the characteristics of the most downloaded and most cited articles in radiology journals. We selected 41 radiology journals that provided lists of both the most downloaded and most cited articles on their websites, and identified the 596 most downloaded articles and 596 most cited articles. We compared the following characteristics of the most downloaded and most cited articles: year of publication, journal title, department of the first author, country of origin, publication type, radiologic subspecialty, radiologic technique and accessibility. Compared to the most cited articles, the most downloaded articles were more frequently review articles (36.1% vs 17.1%, p < 0.05), case reports (5.9% vs 3.2%, p < 0.05), guidelines/consensus statements (5.4% vs 2.7%, p < 0.05), editorials/commentaries (3.7% vs 0.7%, p < 0.05) and pictorial essays (2.0% vs 0.2%, p < 0.05). Compared to the most cited articles, the most downloaded articles more frequently originated from the UK (8.7% vs 5.0%, p < 0.05) and were more frequently free-access articles (46.0% vs 39.4%, p < 0.05). Educational and free-access articles are more frequent among the most downloaded articles. • There was only small overlap between the most downloaded and most cited articles. • Educational articles were more frequent among the most downloaded articles. • Free-access articles are more frequent among the most downloaded articles.

Selection tools for librarians serving this group are available, but only one bibliometric analysis has examined citations to aid collection development. The "Mapping the Literature of Nursing Project" protocol was used. Three source journals were selected, and a citation analysis of articles from 1998 to 2000 was conducted. The frequency of journal citation was tabulated, and a list of the most frequently cited journals was created. Just over 1% of the cited journals produced 33% of the citations. PubMed/MEDLINE, Science Citation Index, and Social Sciences Citation Index provided the most complete indexing coverage of all types of the journals, while CINAHL providing the most complete coverage of nursing journals. Books were the second-most frequently cited format. Citation analysis of journal articles from pediatric nursing journals may be helpful in selecting journals for libraries serving pediatric nurses and those who conduct pediatric nursing research. Librarians should consider adding indexes to their collection in addition to PubMed/MEDLINE to access the broad range of journals useful to this specialty.

    Difficulty managing behavior in the classroom is frequently cited as a source of frustration for teachers and a common reason why new teachers leave the profession (Ingersoll 2001, 2003). Concerted attention to issues of classroom management is important to the health of education; attention to these issues at the middle and secondary education…

  8. The incidental orgasm: the presence of clitoral knowledge and the absence of orgasm for women.

    Women report anorgasmia and other difficulties achieving orgasm. One approach to alleviating this problem is to teach women about the clitoris. This assumes that women lack information about the clitoris and that knowledge about the clitoris is correlated with orgasm. Using a non-random sample of 833 undergraduate students, our study investigates both assumptions. First, we test the amount of knowledge about the clitoris, the reported sources of this knowledge, and the correlation between citing a source and actual knowledge. Second, we measure the correlation between clitoral knowledge and orgasm in both masturbation and partnered sex. Among a sample of undergraduate students, the most frequently cited sources of clitoral knowledge (school and friends) were associated with the least amount of tested knowledge. The source most likely to correlate with clitoral knowledge (self-exploration) was among the most rarely cited. Despite this, respondents correctly answered, on average, three of the five clitoral knowledge measures. Knowledge correlated significantly with the frequency of women's orgasm in masturbation but not partnered sex. Our results are discussed in light of gender inequality and a social construction of sexuality, endorsed by both men and women, that privileges men's sexual pleasure over women's, such that orgasm for women is pleasing, but ultimately incidental.

    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

    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

    To identify and characterize the most frequently cited articles that have been published on aortic dissection. A list of the 100 most frequently cited publications (T100) about aortic dissection was generated by performing a searching of the Science Citation Index--Expanded using "aortic dissection" as the search term. Basic information about the articles was recorded, including number of citations, journal title, journal impact factor, time since publication, first author's country, topic/subspecialty of the research, and publication type. We finally included 180 articles on aortic dissection, from which we identified the 100 most frequently cited articles (T100). The most frequently cited article received 1079 citations, while the least frequently cited article received 68 (mean140.5 citations per article). The T100 originated from 19 countries, with more than half of them originating from the USA (n = 97). The T100 articles were published from 1955 to 2013, with 79% published during the period 1990-2009. In addition, there were 40 different journals with Circulation having the most citations (n = 38). Regarding the article type, there were 21 basic and 140 clinical research articles, one meta-analysis, and 18 review articles. Reviews had the highest mean number of citations (mean 235.5 citations per article). Our study provides a historical perspective on the progress of dissection research, and helps to identify the quality of the work, the discoveries made, and the trends steering the studies.

    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. 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. 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. 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.

    Assessing the impact of individual journal articles provides information for understanding trends in science and translation of findings on practice. Citation analysis is an important way to highlight the contributions of individual author/investigator and journals on nursing practice. The purpose of this study was to identify the most frequently cited articles published in nursing journals from 1956 to 2011. The Science Citation Index Expanded and Social Sciences Citation Index were searched for citations through 2011 to articles published in the 89 nursing journals listed on the Journal Citation Reports (2010 edition). The number of citations, topic, countries, and institutions of origin based on the first author affiliation, year of publication, study design, publishing journal, journal country, and journal impact factor were noted. The most frequently cited articles published in the 89 nursing journals from 1956 to 2011 were identified. The top 50 most frequently cited articles were published in 10 nursing journals between 1970 and 2005. The top cited article received 784 citations. The most common topics were methodology for qualitative studies, validation procedures for tool development, and nursing care and practices in cancer and mental health. The most common study designs were reviews including meta-analysis and instrument validation. Most of the top 50 cited articles were published from 1986 to 1995. The findings provide insights into priorities and trends in nursing research and translational science.

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

    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).

    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.

    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. This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. 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. 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. 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.

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

    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.

    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.

    A content analysis of The New York Times' Science Times section from 1998 to 2012 found evidence of increased source diversity in use of scientific journals as news sources. Science Times increased the frequency at which it cited journals, the number of different journals that it cited, and the number of disciplines represented by cited journals. The results suggest that online availability of a wide array of scientific journals has changed sourcing behaviors. © The Author(s) 2014.

    One of the frequently cited shortcomings of fault-tree models, their inability to model so-called sequence dependencies, is discussed. Several sources of such sequence dependencies are discussed, and new fault-tree gates to capture this behavior are defined. These complex behaviors can be included in present fault-tree models because they utilize a Markov solution. The utility of the new gates is demonstrated by presenting several models of the fault-tolerant parallel processor, which include both hot and cold spares.

    Participation in regular moderate or vigorous physical activity substantially reduces risk for all-cause and cardiovascular-disease mortality and confers other health benefits. Efforts to decrease the population prevalence of inactivity will have a greater impact if they are tailored to the needs and preferences of the community. In the Pilot Survey of the Fitness of Australians, a questionnaire was administered to a randomly selected sample of 2,298 adults and included questions on the preferred sources of assistance or support to become physically active, preferred activities, and barriers to regular participation. The responses of those who were identified as insufficiently physically active (n = 1,232; 53.6%) were examined for men and women separately and for those aged 18 to 39, 40 to 59, and 60 to 78 years. The most-preferred activity was walking (38 and 68% of the youngest and oldest age groups, respectively). The most frequently cited barriers to more-regular participation in the youngest age group were insufficient time, lack of motivation and child care responsibilities. Among those aged 60 to 78 years, injury or poor health were the most frequently cited barriers to activity. The most-preferred source of advice or assistance changed with age: more than 50% of the oldest age group wanted advice from a health professional (compared with 22% of the youngest group) and the opportunity to exercise with a group was the most preferred source of support for the youngest age group. The physical activity-related attributes of men and women and of younger and older age groups described in this study may be used to provide more relevant and appealing options for those who might otherwise be missed by "one-size-fits-all" physical activity promotion strategies.

    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. Three source journals were selected and subjected to a citation analysis of articles from 1996 to 1998. 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. 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.

    The citation number of an article gives us information about its quality and contribution to science. In this article, we aimed to find the most frequently cited article in general surgery from Turkey, and evaluate how these articles in general surgery contributed to the world literature. We used the science citation index expanded database to find the most frequently cited articles in general surgery from Turkey. Among the 52 articles found, the most common subjects were as follows: hydatid cyst (21.1%), pilonidal disease (15.4%), laparoscopic operations (15.4%), breast diseases (11.5%), and inguinal hernia (7.7%). Two articles were cited in more than 100 articles. Furthermore, 48.8% of the articles were published from three major cities. Most articles were published between 2000 and 2004, and 65.4% of articles were case series. Most of the cited articles were about hydatid cyst and pilonidal disease, which are more common in the Turkish population compared with other countries. Evaluation of most cited articles is important to identify the fields in which Turkey contributes to the world literature.

    2012-08-01

    The 126 most frequently cited articles published in the adsorption field between 1900 and 2011 were identified and characterized using the Science Citation Index (Expanded). The data analyzed cover a range of publication years, journals, Web of Science categories, authors, institutions, countries/territories, life citation cycle curves, and characteristics of frequently cited articles. The 126 most-frequently-cited articles were each cited an average of 1014 times, ranging from 502 to 9922 citations per article from 1918 to 2006; 80% of these articles were published after 1970. Fifty-five journals were represented, led by the Journal of the American Chemical Society, and followed by Science and Nature. Three categories out of the 35 Web of Science categories constituted 60% of the citations. The three categories were: physical chemistry, multidisciplinary chemistry, and multidisciplinary sciences. Thirteen of the authors contributed three or more articles. Harvard University, the Massachusetts Institute of Technology, and the University of Washington led the list of 107 institutions, while the United States led the list of 17 countries/territories, comprising more than half of the articles. Collaboration among the top authors was a frequent occurrence, while inter-institutional collaboration and national collaboration was not obvious among the topmost articles. Moreover, the citation patterns as a function of time varied widely among the topmost articles. As evidenced by citation life cycles, the well known BET and Langmuir isotherms have received considerable attention during the study period, and will probably continue to be popular in the adsorption field. Some emerging hotspots are likely to receive particular attention in the near future; these include the new family of "M41S" materials, pseudo-second-order kinetic models, and the nudged elastic band method.

    Citation is one of the important metrics that are used in measuring the relevance and the impact of research publications. The potentials of citation analytics may be exploited to understand the gains of publishing scholarly peer-reviewed research outputs in either Open Access (OA) sources or Subscription-Based (SB) sources in the bid to increase citation impact. However, relevant data required for such comparative analysis must be freely accessible for evidence-based findings and conclusions. In this data article, citation scores ( CiteScores ) of 2542 OA sources and 15,040 SB sources indexed in Scopus from 2014 to 2016 were presented and analyzed based on a set of five inclusion criteria. A robust dataset, which contains the CiteScores of OA and SB publication sources included, is attached as supplementary material to this data article to facilitate further reuse. Descriptive statistics and frequency distributions of OA CiteScores and SB CiteScores are presented in tables. Boxplot representations and scatter plots are provided to show the statistical distributions of OA CiteScores and SB CiteScores across the three sub-categories (Book Series, Journal, and Trade Journal). Correlation coefficient and p-value matrices are made available within the data article. In addition, Probability Density Functions (PDFs) and Cumulative Distribution Functions (CDFs) of OA CiteScores and SB CiteScores are computed and the results are presented using tables and graphs. Furthermore, Analysis of Variance (ANOVA) and multiple comparison post-hoc tests are conducted to understand the statistical difference (and its significance, if any) in the citation impact of OA publication sources and SB publication source based on CiteScore . In the long run, the data provided in this article will help policy makers and researchers in Higher Education Institutions (HEIs) to identify the appropriate publication source type and category for dissemination of scholarly research findings with maximum citation impact.

    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.

    Caesarean section (CS) rates are increasing worldwide and maternal request is cited as one of the main reasons for this trend. Women's preferences for route of delivery are influenced by popular media, including magazines. We assessed the information on CS presented in Spanish women's magazines. Systematic review. Women's magazines printed from 1989 to 2009 with the largest national distribution. Articles with any information on CS. Articles were selected, read and abstracted in duplicate. Sources of information, scientific accuracy, comprehensiveness and women's testimonials were objectively extracted using a content analysis form designed for this study. Accuracy, comprehensiveness and sources of information. Most (67%) of the 1223 selected articles presented exclusively personal opinion/birth stories, 12% reported the potential benefits of CS, 26% mentioned the short-term and 10% mentioned the long-term maternal risks, and 6% highlighted the perinatal risks of CS. The most frequent short-term risks were the increased time for maternal recovery (n = 86), frustration/feelings of failure (n = 83) and increased post-surgical pain (n = 71). The most frequently cited long-term risks were uterine rupture (n = 57) and the need for another CS in any subsequent pregnancy (n = 42). Less than 5% of the selected articles reported that CS could increase the risks of infection (n = 53), haemorrhage (n = 31) or placenta praevia/accreta in future pregnancies (n = 6). The sources of information were not reported by 68% of the articles. The portrayal of CS in Spanish women's magazines is not sufficiently comprehensive and does not provide adequate important information to help the readership to understand the real benefits and risks of this route of delivery. © 2014 The Authors.

    Systematic analysis of STD programme data contributes to a national portrait of sexually transmitted disease (STD) prevention activities, including research and evaluation specifically designed to optimise programme efficiency and impact. We analysed the narrative of the 2009 annual progress reports of the US Comprehensive STD Prevention Systems cooperative agreement for 58 STD programmes, concentrating on programme characteristics and partnerships. Programmes described 516 unique partnerships with a median of seven organisations cited per STD programme. Non-profit organisations (including service providers) were most frequently cited. Higher gonorrhoea morbidity was associated with reporting more partnerships; budget problems were associated with reporting fewer. Challenges to engaging in partnerships included budget constraints, staff turnover and low interest. Data provide a source of information for judging progress in programme collaboration and for informing a sustained programme-focused research and evaluation agenda.

    2006-04-01

    Medical-surgical or adult health nursing is a complex specialty that requires a wide-ranging literature to inform its research and practice. Several excellent qualitative aids exist for collection development for this field, but quantitative studies are few. While one bibliometric study of journals exists, no recent work had been done in this area. The Mapping the Literature of Nursing Project protocol was used. Four source journals were selected, and a citation analysis of articles from 1996 to 1998 was conducted. A list of the most frequently cited journals was created, using Bradford's Law of Scattering. The list demonstrates that 1.2% of the cited medical-surgical nursing journals produced just over 33% of the citations. PubMed/MEDLINE, CINAHL, and Science Citation Index provided the most complete indexing coverage of all of the journals, with CINAHL providing the most complete coverage of nursing journals. Books were the second-most cited format. Citation analysis of journal articles is a useful aid for selecting journals for medical-surgical nursing collections, but it did not prove to be as useful for selecting materials in other formats. Indexes in addition to PubMed/MEDLINE are necessary to provide access to the journal literature serving this specialty.

    We identify the most cited articles that have influenced the clinical practices of neurologists. We first analyzed the top 100 cited articles published in 50 neurology journals with high impact factors. We collected all of the original articles on clinical neurology published in all 554 medical journals. The Institute for Scientific Information Web of Science search tools were used to identify the top 100 cited articles in the database of Journal Citation Reports since 1950, which were then manually reviewed to discover their contents. In the first part of analysis, the top 100 cited articles were all published in 17 journals, with 26 articles published in Neurology. The most frequent topic subject of neurodegeneration appeared in 40 articles. The second part of the analysis revealed that the top 100 cited articles were also all published in 17 journals, with 30 articles published in New England Journal of Medicine. In contrast to the first part of the analysis, stroke was the most frequent topic subject (in 38 articles). Our bibliometric analysis has yielded 2 detailed lists of the top 100 cited articles that were listed separately using different methods. This approach can provide information about the trends and academic achievements in the field of clinical neurology. © 2017 S. Karger AG, Basel.

    Prompted by patients' changing perceptions of transvaginal mesh, this study examines how mesh has been reported in the news following the 2011 US Food and Drug Administration (FDA) updated notification about the use of mesh in the treatment of pelvic organ prolapse. Two national newspaper databases were queried for articles discussing transvaginal mesh published within 3 years of the FDA announcement. Content analysis included headline subjects, mesh-related complications, quoted sources, and the FDA recommendations. To determine whether more widely read sources publish higher quality reporting, a subgroup analysis was conducted based on newspaper circulation. Ninety-five articles met inclusion criteria. Mesh-related litigation was the most common headline subject (36 articles, 38%), and 54% of all articles referenced legal action. Fifty-seven articles (60%) cited at least one mesh-related complication. Only 18 articles (19%) quoted surgeons who use transvaginal mesh. For the FDA update, 40% of articles that first reported the announcement accurately specified that it applies to mesh for prolapse, not incontinence. This ambiguity persisted: half of all articles cited the warning, but only 23% distinguished between prolapse and incontinence. Higher newspaper circulation did not significantly improve the quality of reporting about the content or context of the FDA's recommendations. Despite frequent media coverage of transvaginal mesh and its complications since 2011, very few news sources that cited the FDA warning distinguished between prolapse and incontinence. Given prevalent reporting of mesh-related litigation, the findings raise concern about how patients perceive the safety and efficacy of transvaginal mesh, regardless of indication. Neurourol.

    The purpose of this study was to identify the characteristics associated with highly cited papers in orthognathic surgery. This was a cohort study of articles published in the English-language literature from 1900 to 2017. Citation databases were searched for papers related to orthognathic surgery and the most frequently cited papers were identified. For each paper, the following variables were collected: region of origin, time-period of publication, corresponding author specialty, journal of publication, topic area, study design, and number of citations. The outcome variable was the citation index (citations per year). North American investigators published 70% of the 100 most-cited articles in orthognathic surgery. The majority of papers were from oral and maxillofacial surgeons. Frequent content areas were diagnosis, virtual planning, fixation/stability, and complications. The majority (54%) of studies were cohort or case report/series. The mean number of citations was 235.0±126.5; the mean citation index was 9.9±6.1 citations per year. Time-period, content area, and study design were associated with the citation index (all P<0.001). Time-period, content area, and study design predicted the citation index (all P≤0.009). Among frequently cited papers in orthognathic surgery, oral and maxillofacial surgeons had the highest volume of contributions. Diagnosis, treatment planning, and complications were the most common topics studied. Copyright © 2018 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    Objectives To explore beliefs and apprehensions about disease and its treatment in patients with rheumatoid arthritis and spondyloarthritis. Methods 25 patients with rheumatoid arthritis and 25 with spondyloarthritis participated in semi-structured interviews about their disease and its treatment. The interviews were performed by trained interviewers in participants' homes. The interviews were recorded and the main themes identified by content analysis. Results Patients differentiated between the underlying cause of the disease, which was most frequently identified as a hereditary or individual predisposition. In patients with rheumatoid arthritis, the most frequently cited triggering factor for disease onset was a psychological factor or life-event, whereas patients with spondyloarthritis tended to focus more on an intrinsic vulnerability to disease. Stress and overexertion were considered important triggering factors for exacerbations, and relaxation techniques were frequently cited strategies to manage exacerbations. The unpredictability of the disease course was a common source of anxiety. Beliefs about the disease and apprehensions about the future tended to evolve over the course of the disease, as did treatment expectations. Conclusions Patients with rheumatoid arthritis and spondyloarthritis hold a core set of beliefs and apprehensions that reflect their level of information about their disease and are not necessarily appropriate. The physician can initiate discussion of these beliefs in order to dispel misconceptions, align treatment expectations, provide reassurance to the patient and readjust disease management. Such a dialogue would help improve standards of care in these chronic and incapacitating diseases. PMID:25474157

    Citation analysis represents one of the best currently available methods for quantifying the impact of articles. Bibliometric studies list the ''best sellers'' in a single field of interest. The purpose of the present study was to identify and analyze the most frequently cited papers in dry eye research that may be of high interest for researchers and clinicians. We reviewed the database of the Institute for Scientific Information to identify articles published from 1900 to September 2016. All dry eye articles published in 59 ophthalmology journals were identified. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. The 100 most-cited articles were published between 1983 and 2011, with most of them in the 2000s. The number of citations per article ranged from 96 to 610, and was greatest for articles published in the 2000s. Each of these articles was published in one of 15 journals. Most articles represented Level-III evidence, followed by Levels II and I. The present study focusing on dry eye research revealed that 55% of the most-cited articles came from the U.S. and 18% from Japan. Diagnostics and therapy were the areas of focus of most of the clinical articles; 13% of the most cited papers were review articles. This analysis provides researchers and clinicians with a detailed overview on the most cited dry eye papers over the past decades. Copyright © 2017 Elsevier Inc. All rights reserved.

  4. Professional isolation and connection among high school science teachers in upstate New York

    Abrams, Robert H., Jr.

    Where does Professional Isolation and Connection come from, are there differences in how different teachers experience it, how do teachers get from isolation to connection, and are there reasons to not want to make the trip? Previous research in this area explored the relationship between professional isolation and autonomy, but had not considered what education might look like if professional isolation were replaced with its opposite. This study used a written survey which gathered representative data from a broad geographical region. This strategy was employed so that the results would not be influenced by any one teacher enhancement program. The survey was designed to embody features of clinical interviews. Such features include short answer questions derived from the experience of practicing teachers, and open-ended questions which probe specific responses in the short answer questions. This study found that "Lack of Time" was the most frequently cited source of professional isolation, and "Friendship" was the most frequently cited source of professional connection. Unexpectedly infrequent sources include "Layout of instructional space" as a source of isolation, and "Computer networks" as a source of connection. Teachers have relationships with other teachers which are primarily characterized by connection, although there is room for improvement. Productive relationships at the state level are higher than expected and probably reflect the efforts of statewide organizations, and conversely there is a gap in the number of teachers reporting productive relationships with other teachers who work in other parts of their county. It is suggested that schools avoid policies that make it difficult to have friendships, encourage teachers to go to state conferences and provide facilitated follow-up, encourage county-based organizations to develop opportunities for teachers to utilize each other as sources of assistance, capitalize on the prevalence of productive relationships in teachers' own schools by explicitly linking such intra-school communities with one or more inter-school communities, and budget time for teachers to connect with each other. Finally, teachers should not only be encouraged to seek and give each other assistance, but should be thought of as scholars as well as teachers and be paid accordingly.

    Citation analysis helps to identify the research trends within a research field and helps to identify the most frequently occurring parameters. The aim of this study was to identify the 100 most-cited articles in the field of dental, oral, and maxillofacial traumatology over the past 64 years. A comprehensive list of the most-cited articles in dental, oral, and maxillofacial trauma was compiled using 'All Databases' section of the ISI Web of Knowledge. Related articles were considered to be those articles in which part or all of the experiment or study was related to dental and/or oral and maxillofacial trauma. In case reports, if a part of a treatment plan was related to the topic, that article was considered to be relevant. The characteristics analyzed included number of citations, authors, journals, institution, country of origin, publication year, article type, study material, and topic. The number of citations for each article ranged from 69 to 229. The journal Dental Traumatology was the most represented, followed by the journal Oral and Maxillofacial Surgery. Of the 100 articles, 83% were original articles, 15% were review articles, and 2% were case report/case series. Therapy and prognosis-related topics were the most common topics. Most articles came from institutions in the United States, followed by the Scandinavian countries. University Hospital of Copenhagen was the source of the highest number (34) of the most-cited articles; the same author wrote or co-wrote 22 of the 100 most-cited articles. The list of most-cited articles in the field of dental, oral, and maxillofacial traumatology gives a good scientometric picture of trauma research in the world. A large number of the most-cited articles are mainly from the field of dental traumatology and originate from a few research teams. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We investigated the liver transplantation literature since 1975 and found the most frequently cited 100 articles and assessed the distribution of authors and journals of these articles. Using the advanced mode of the Institute for Scientific Information (ISI) Web of Science (WOS) search engine, the words "SU = transplantation AND TI = liver OR SU = transplantation AND TS = liver" were used to scan articles and determine the most-cited 100 articles on July 18, 2016. From 1975 to date, it appears a total of 43,369 articles were published in the field of liver transplantation in the WOS. Although the most cited article had 677 citations, the least cited article had 180 citations. The mean citation number for the 100 articles was 252.31 ± 96.75. The mean annual citation number for the articles varied from 61.55 to 5 and the mean was 15.31 ± 8.63. The most cited article was by Feng et al "Characteristics Associated With Liver Graft Failure: The Concept of a Donor Risk Index" published in the American Journal of Transplantation (677 citations). Bibliometric analysis highlights the key topics and publications that have shaped the understanding and management of liver transplantation. According to our research, this is the first study to investigate articles with most citations in the field of liver transplantation. In our study the article with the most citations was cited 677 times, whereas the 100th article was cited 180 times with a mean citation number for the 100 articles of 252.31 ± 96.75.

    This study examined dissemination and reporting biases in the brief alcohol intervention literature. We used retrospective data from 179 controlled trials included in a meta-analysis on brief alcohol interventions for adolescents and young adults. We examined whether the magnitude and direction of effect sizes were associated with publication type, identification source, language, funding, time lag between intervention and publication, number of reports, journal impact factor, and subsequent citations. Results indicated that effect sizes were larger for studies that had been funded (b = 0.14, 95% confidence interval [CI] [0.04, 0.23]), had a shorter time lag between intervention and publication (b = −0.03, 95% CI [−0.05, −.001]), and cited more frequently (b = 0.01, 95% CI [+0.00, 0.01]). Studies that were cited more frequently by other authors also had greater odds of reporting positive effects (odds ratio = 1.10, 95% CI [1.02, 1.18]). Results indicated that time lag bias has increased recently: larger and positive effect sizes were published more quickly in recent years. We found no evidence, however, that the magnitude or direction of effects was associated with location source, language, or journal impact factor. We conclude that dissemination biases may indeed occur in the social and behavioral science literature, as has been consistently documented in the medical literature. As such, primary researchers, journal reviewers, editors, systematic reviewers, and meta-analysts must be cognizant of the causes and consequences of these biases, and commit to engage in ethical research practices that attempt to minimize them.

    Obstetrics and gynecology (ob/gyn) is fraught with bioethical issues, the professional significance of which may vary based on clinical experience. Our objective was to utilize our novel ethics curriculum to identify ethics and professionalism issues highlighted by ob/gyn learners and to compare responses between learner levels to further inform curricular development. We introduced an integrated and dynamic ob/gyn ethics and professionalism curriculum and mixed methods analysis of 181 resulting written reflections (case observation and assessments) from third-year medical students and from first- to fourth-year ob/gyn residents. Content was compared by learner level using basic thematic analysis and summary statistics. Within the 7 major ethics and professionalism domains, learners wrote most frequently about miscellaneous ob/gyn issues such as periviability and abortion (22% of students, 20% of residents) and problematic treatment decisions (20% of students, 19% of residents) rather than professional duty, communication, justice, student-/resident-specific issues, or quality of care. The most commonly discussed ob/gyn area by both learner groups was obstetrics rather than gynecology, gynecologic oncology, or reproductive endocrinology and infertility, although residents were more likely to discuss obstetrics-related concerns than students (65% vs 48%; P = .04) and students wrote about gynecologic oncology-related concerns more frequently than residents (25% vs 6%; P = .002). In their reflections, sources of ethical value (eg, the 4 classic ethics principles, professional guidelines, and consequentialism) were cited more frequently and in greater number by students than by residents (82% of students cited at least 1 source of ethical value vs 65% of residents; P = .01). Residents disagreed more frequently with the ethical propriety of clinical management than did students (67% vs 43%; P = .005). Our study introduces an innovative and dynamic approach to an ob/gyn ethics and professionalism curriculum that highlights important learner-identified ethics and professionalism issues both specific to ob/gyn and common to clinical medicine. Findings will help ob/gyn educators best utilize and refine this flexible curriculum such that it is appropriately focused on topics relevant to each learner level. Copyright © 2015 Elsevier Inc.

    Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer-reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non-OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e.g., review or research paper), length of paper, authors' citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author-archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.

  11. Decoding the codes: A content analysis of the news coverage of genetic cloning by three online news sites and three national daily newspapers, 1996 through 1998

    NASA Astrophysics Data System (ADS)

    Hyde, Jon E.

    This study compared news coverage of genetic cloning research in three online news sites (CNN.com, ABC.com, and MSNBC.com) and three national daily newspapers (The New York Times, The Washington Post, and USA Today). The study involved the analysis of 230 online and print news articles concerning genetic cloning published from 1996 through 1998. Articles were examined with respect to formats, sources, focus, tone, and assessments about the impact of cloning research. Findings indicated that while print news formats remained relatively constant for the duration of this study, online news formats changed significantly with respect to the kinds of media used to represent the news, the layouts used to represent cloning news, and the emphasis placed on audio-visual content. Online stories were as much as 20 to 70% shorter than print stories. More than 50% of the articles appearing online were composed by outside sources (wire services, guest columnists, etc.). By comparison, nearly 90% of the articles published by print newspapers were written "in-house" by science reporters. Online news sites cited fewer sources and cited a smaller variety of sources than the newspapers examined here. In both news outlets, however, the sources most frequently cited were those with vested interests in furthering cloning research. Both online and print news coverage of cloning tends to focus principally on the technical procedures and on the future benefits of cloning. More than 60% of the articles focused on the techniques and technologies of cloning. Less than 25% of the articles focused on social, ethical, or legal issues associated with cloning. Similarly, articles from all six sources (75%) tended to be both positive and future-oriented. Less than 5% of the total articles examined here had a strongly negative or critical tone. Moreover, both online and print news sources increasingly conveyed a strong sense of acceptance about the possibility of human cloning. Data from this study are among the first to indicate the ways in which online news outlets are transforming science news. Furthermore, this study reaffirms the need for a greater diversity of sources in assessing a broader spectrum of issues related to cloning.

    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.

    2018-05-01

    In this study, we bibliometrically evaluated the top 100 cited articles on urological emergencies published since 1975 with a multidisciplinary and interdisciplinary perspective. 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. 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). 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.

    Individuals often apply social rules when they interact with computers, and this is known as the Computers Are Social Actors (CASA) effect. Following previous work, one approach to understand the mechanism responsible for CASA is to utilize computer agents and have the agents attempt to gain human compliance (e.g., completing a pattern recognition task). The current study focuses on three key factors frequently cited to influence traditional notions of compliance: evaluations toward the source (competence and warmth), normative influence (reciprocity), and affective influence (mood). Structural equation modeling assessed the effects of these factors on human compliance with computer request. The final model shows that norm-based influence (reciprocity) increased the likelihood of compliance, while evaluations toward the computer agent did not significantly influence compliance.

    The purpose of this study was to make a brief diagnosis of the evolution of the Journal of Applied Oral Science (JAOS) between 2005 and 2007, by reviewing quantitative and qualitative aspects of the articles published in the JAOS within this period. All articles published in the JAOS in the time span established for this survey were analyzed retrospectively and a discussion was undertaken on the data referring to the main bibliometric indexes of production, authorship, bibliographic sources of the published articles, and the most frequently cited scientific journals in the main dental research fields. A total of 247 papers authored and coauthored by 1,139 contributors were reviewed, most of them being original research articles. The number of authors per article was 4.61 on the average. Regarding the geographic distribution, the authors represented almost all of the Brazilian States. Most published articles belonged to the following dental research fields: Endodontics, Restorative Dentistry, Dental Materials and Prosthodontics. The ranking of the most frequently cited scientific journals included the most reputable publications in these dental research fields. In conclusion, between 2005 and 2007, the JAOS either maintained or improved considerably its bibliometric indexes. The analysis of the data retrieved in this study allowed evaluating the journal's current management strategies, and identifying important issues that will help outlining the future directions for the internationalization of this journal.

    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

  2. Use and misuse of research in books on sex trafficking: implications for interdisciplinary researchers, practitioners, and advocates.

    2015-04-01

    Recent articles have raised important questions about the validity of prevalence data on human trafficking, exposing flawed methodologies behind frequently cited statistics. While considerable evidence points to the fact that human trafficking does exist in the United States and abroad, many sources of literature continue to cite flawed data and some misuse research in ways that seemingly inflate the problem, which can have serious implications for anti-trafficking efforts, including victim services and anti-trafficking legislation and policy. This systematic review reports on the prevalence data used in 42 recently published books on sex trafficking to determine the extent to which published books rely on data estimates and just how they use or misuse existing data. The findings from this review reveal that the vast majority of published books do rely on existing data that were not rigorously produced and therefore may be misleading or at minimum, inaccurate. Implications for practice, research, and policy are discussed, as well as recommendations for future prevalence studies on human trafficking. © The Author(s) 2014.

    To identify the major perceived influences on food choice, to examine the use of and trust in information sources concerning healthy eating, and to assess attitudes towards and barriers to adopting healthy eating practices in a post-USSR country (Ukraine). A survey of an urban adult population. The questions were adopted from the Pan-European Union (EU) Survey of Consumer Attitudes to Food, Nutrition and Health (1995-1996). Lviv city, Ukraine. The survey included 296 adults (84 males, 212 females) aged 18-55 years; they were primarily college students and subjects with tertiary education--the groups most likely to be both interested in healthy eating and affected by current socioeconomic downturns. The major factors in food choice were: 'quality/freshness' (cited by 80%), 'price' (58%) and 'taste' (47%); only 34% cited 'trying to eat healthily'. More older people cited 'price' than 'quality/freshness', and men were more likely than women to cite 'taste'. Sources of healthy eating information included: 'relatives/friends' (cited by 65%, trusted by 85%) and health professionals (trusted by 92%, but used by only 35%); while advertising was the least trusted source (cited by 28%). Fifty-three per cent of respondents considered their diet to be healthy enough without further changes; 50% thought of the nutritional aspects of the food they ate; fewer women than men considered their diet healthy, and more women than men thought about nutrition. Barriers to healthy eating included: 'cost' (cited by 65%), 'lack of time' (55%), 'self-control' (54%), 'selection influences' (41%), 'lack of knowledge' (32%), 'unpleasant foods' and 'resistance to change' (both 30%). Strategies to encourage healthy eating in this population should involve word-of-mouth nutrition education concerning low-cost healthy alternatives.

    The frequency with which a scientific article is cited by other studies is one way to measure its academic influence. A comprehensive search was performed to identify journal articles in the otorhinolaryngology subject category of the 2013 Journal Citation Report Science Edition over the last 30 years (1985-2014). The 100 most cited articles were reviewed and basic information including the publication year, country of origin, source journal, article type and research field was collected. The 100 most cited articles were published in 15 of the 44 otorhinolaryngology journals. The number of citations per article ranged between 208 and 1559. The leading research field was otology and neurotology (n = 50), followed by rhinology (n = 23) and head and neck surgery (n = 11). Most papers originated in the USA (n = 64). The possibility of an article being cited is influenced by the publication language, country of origin and source journal.

    Wind tunnels have been widely employed in aerodynamic research. To characterize the high impact research, a bibliometric analysis was conducted on highly cited articles related to wind tunnel based on the Science Citation Index Expanded (SCI-EXPANDED) database from 1900 to 2014. Articles with at least 100 citations from the Web of Science Core Collection were selected and analyzed in terms of publication years, authors, institutions, countries/territories, journals, Web of Science categories, and citation life cycles. The results show that a total of 77 highly cited articles in 37 journals were published between 1959 and 2008. Journal of Fluid Mechanics published the most of highly cited articles. The USA was the most productive country and most frequent partner of internationally collaboration. The prolific institutions were mainly located in the USA and UK. The authors who were both first author and corresponding author published 88% of the articles. The Y index was also deployed to evaluate the publication characteristics of authors. Moreover, the articles with high citations in both history and the latest year with their citation life cycles were examined to provide insights for high impact research. The highly cited articles were almost earliest wind tunnel experimental data and reports on their own research specialty, and thus attracted high citations. It was revealed that classic works of wind tunnel research was frequently occurred in 1990s but much less in 2000s, probably due to the development of numerical models of computational fluid dynamic (CFD) in recent decades.

  7. Conflicts of interest and critiques of the use of systematic reviews in policymaking: an analysis of opinion articles

    PubMed Central

    2014-01-01

    Background Strong opinions for or against the use of systematic reviews to inform policymaking have been published in the medical literature. The purpose of this paper was to examine whether funding sources and author financial conflicts of interest were associated with whether an opinion article was supportive or critical of the use of systematic reviews for policymaking. We examined the nature of the arguments within each article, the types of disclosures present, and whether these articles are being cited in the academic literature. Methods We searched for articles that expressed opinions about the use of systematic reviews for policymaking. We included articles that presented opinions about the use of systematic reviews for policymaking and categorized each article as supportive or critical of such use. We extracted all arguments regarding the use of systematic reviews from each article and inductively coded each as internal or external validity argument, categorized disclosed funding sources, conflicts of interest, and article types, and systematically searched for undisclosed financial ties. We counted the number of times each article has been cited in the “Web of Science.” We report descriptive statistics. Results Articles that were critical of the use of systematic reviews (n = 25) for policymaking had disclosed or undisclosed industry ties 2.3 times more often than articles that were supportive of the use (n = 34). We found that editorials, comments, letters, and perspectives lacked published disclosures nearly twice as often (60% v. 33%) as other types of articles. We also found that editorials, comments, letters, and perspectives were less frequently cited in the academic literature than other article types (median number of citations = 5 v. 19). Conclusions It is important to consider whether an article has industry ties when evaluating the strength of the argument for or against the use of systematic reviews for policymaking. We found that journal conflict of interest disclosures are often inadequate, particularly for editorials, comments, letters, and perspectives and that these articles are being cited as evidence in the academic literature. Our results further suggest the need for more consistent and complete disclosure for all article types. PMID:25417178

    Pharmaceutical sales representatives (drug reps) frequently visit 70% to 90% of physicians during their daily clinical practice and many consider the promotional printed material to be a major source of clinical information. We evaluated samples of the promotional printed material distributed to physicians by drug reps in order to determine whether the data contained in the promotional material is correct and supported by references accessible in Argentina. A consecutive sample of all the promotional material distributed by drug reps in the general internal medicine program (Hospital de Clínicas) was collected between March 15 and April 15, 2000. Reprints and monographs were excluded. Clinical information was reviewed by two general internists and compared to information in a major pharmacology textbook and in an electronic medical information program. References cited were reviewed for correct listing and accessibility in any of the four major medical libraries in Buenos Aires. Of the sixty-four pieces of promotional material collected, thirty were randomly selected and evaluated. In twenty one (70%) the therapeutic effect promoted in advertisement appeared in Goodman & Gilman's 9th edition textbook of pharmacology, in the pharmacology section of the Up-to-Date version 8.1 or in both. Only eighteen (60%) of the thirty promotional printed material evaluated had statements supported by cited references. From a total of 131 references cited in promotional materials, sixty (46%) were incorrectly listed according to the International Committee of Medical Journal Editors. These references were inaccessible. Of the 71 references correctly cited, 49 (69%) were not available in any of the four major medical libraries in Buenos Aires and 8 were available in only two of the libraries. Twenty-two references were reviewed, and in twelve of these (54%), the objective of the research study concurred with the statement of the promotional printed material. Adverse reactions, warnings about drug interactions and contraindications were absent from all promotional printed material. It can be concluded that the promotional printed material distributed by the drug reps in Buenos Aires are biased and provide misinformation more often than not. We recommend that practicing physicians routinely disregard promotional printed material as a source of clinical information.

    The purpose of this study was to identify and review the most cited articles in the occupational therapy field. Using the multi-disciplinary Publish or Perish software to extract data, the top 50 lifetime and annual cited articles were examined. Studies were organized according to the following: year of publication, design, topic, number of authors, country of publication, and number of citations for each cohort. We found that randomized control trials were the dominant design type used in papers with the most lifetime (36.0%) and annual (26.0%) citations. Additionally, in both groups, the most frequently cited articles investigated predictors of functional outcome for patients. This comprehensive citation analysis will inform future research through its identification of major trends and well-established areas of study.

  10. Ancient "Observatories" - A Relevant Concept?

    NASA Astrophysics Data System (ADS)

    Belmonte, Juan Antonio

    It is quite common, when reading popular books on astronomy, to see a place referred to as "the oldest observatory in the world". In addition, numerous books on archaeoastronomy, of various levels of quality, frequently refer to the existence of "prehistoric" or "ancient" observatories when describing or citing monuments that were certainly not built with the primary purpose of observing the skies. Internet sources are also guilty of this practice. In this chapter, the different meanings of the word observatory will be analyzed, looking at how their significances can be easily confused or even interchanged. The proclaimed "ancient observatories" are a typical result of this situation. Finally, the relevance of the concept of the ancient observatory will be evaluated.

    Masters, Ken

    2013-11-01

    Edgar Dale's Pyramid of Learning and percentages of retained learning are cited in educational literature in a range of disciplines. The sources of the Pyramid, however, are misleading. To examine the evidence supporting the Pyramid and the extent to which it is cited in medical education literature. A review of literature (1946-2012) based on a search utilising Academic Search Complete, CINAHL, Medline and Google Scholar conducted from September to November 2012. A total of 43 peer-reviewed medical education journal articles and conference papers were found. While some researchers had been misled by their sources, other authors' interpretations of the citations did not align with the content of those citations, had no such citations, had circular references, or consulted questionable sources. There was no agreement on the percentages of learning retention, in spite of many researchers' citing primary texts. The inappropriate citing of the Pyramid and its associated percentages in medical education literature is widespread and continuous. This citing undermines much of the published work, and impacts on research-based medical education literature. While the area of learning/teaching strategies and amount of retention from each is an area for future research, any reference to the Pyramid should be avoided.

    The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics. The 50 highest cited articles related to Anterior Cruciate Ligament Injury were searched in Thomson ISI Web of Science® by the use of defined search terms. All types of scientific papers with reference to our topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type and level of evidence. The 50 highest cited articles had up to 1624 citations. The top ten papers on this topic were cited 600 times at least. Most papers were published in the American Journal of Sports Medicine. The publication years spanned from 1941 to 2007, with the 1990s and 2000s accounting for half of the articles (n = 25). Seven countries contributed to the top 50 list, with the USA having by far the most contribution (n = 40). The majority of articles could be attributed to the category "Clinical Science & Outcome". Most of them represent a high level of evidence. Scientific articles in the field of ACL injury are highly cited. The majority of these articles are clinical studies that have a high level of evidence. Although most of the articles were published between 1990 and 2007, the highest cited articles in absolute and relative numbers were published in the early 1980s. These articles contain well established scoring- or classification systems. The identification of important papers will help current clinicians and scientists to get an overview on past and current trends in that special field of ACL injury and provides a basis for both further discussion as well as future research.

    Neurorehabilitation covers a large range of disorders, assessment approaches and treatment methods. There have been previous citation analyses of rehabilitation and of its subfields. However, there has never been a comprehensive citation analysis in neurorehabilitation. The present study reports findings from a citation analysis of the top 100 most cited neurorehabilitation papers to describe the research trends in the field. A de-novo keyword search of papers indexed in the Web of Science Core Collection database yielded 52,581 papers. A candidate pool of the 200 most-cited papers published between 2005 and 2016 was reviewed by the clinician authors. The papers in the top 100 deemed to be irrelevant were discarded and replaced by the most highly-cited articles in the second tier deemed to be clinically relevant. The most frequently cited neurorehablitation papers appeared in Stroke, Movement Disorders, and Neurology. Papers tended to focus on treatments, especially for stroke. Authorship trends suggest that top cited papers result from group endeavors, with 90% of the papers involving a collaboration among 3 or more authors. Treatment studies, often focused on stroke, appear to have the highest impact in the field of neurorehabilitation.

    Solitude is a frequently cited motive for visiting parks, forests, and wilderness areas. But while visitors frequently say they achieve their solitude goals, most visit in groups of two or more, suggesting a conception that differs from the classical ideal of being profoundly alone with the universe. Moreover, solitude often can be experienced negatively, surrounded by...

    With the current and projected shortages of general surgeons, more attention is being paid to the increasing pool of women physicians. This study seeks to understand the variables leading to career satisfaction for women surgeons to better recruit, retain, and support them. Eighteen semi-structured interviews of 12 female and 6 male surgeons 2 to 12 years into practice were qualitatively analyzed and converted to coded, categorized data. Significance was derived by Fisher's exact test. Participants were recruited by snowball sampling. Our sample represents a highly satisfied group of female and male surgeons. Although both women and men describe with equal frequency having made career tradeoffs for personal and family time, and vice versa, women far more frequently than men cite reasons related to their personal time, predictable time, and family relationships as why they are currently satisfied with their career (34.1% versus 8.7%; p < 0.05). Both cite being satisfied by career content equally. When describing strategies used in developing a successful surgical career, women most frequently cite social networks as a key to success (88% versus 12% by men; p < 0.05), and men more frequently cite reasons related to training (29% versus 0% by women; p < 0.05) and compensation (24% versus 0% by women; p < 0.05). Although both men and women make tradeoffs of career for family and family for career, women's perception of satisfaction comes from viewing their surgical career within the broader context of their lives. Women might be attracted to a career that acknowledges and values the whole person beyond the surgeon, and could benefit from work infrastructures that enhance networking.

    2017-06-01

    Payers are faced with making coverage and reimbursement decisions based on the best available evidence. Often these decisions apply to patient populations, provider networks, and care settings not typically studied in clinical trials. Treatment effectiveness evidence is increasingly available from electronic health records, registries, and administrative claims. However, little is known about when and what types of real-world evidence (RWE) studies inform pharmacy and therapeutic (P&T) committee decisions. To evaluate evidence sources cited in P&T committee monographs and therapeutic class reviews and assess the design features and quality of cited RWE studies. A convenience sample of representatives from pharmacy benefit management, health system, and health plan organizations provided recent P&T monographs and therapeutic class reviews (or references from such documents). Two investigators examined and grouped references into major categories (published studies, unpublished studies, and other/unknown) and multiple subcategories (e.g., product label, clinical trials, RWE, systematic reviews). Cited comparative RWE was reviewed to assess design features (e.g., population, data source, comparators) and quality using the Good ReseArch for Comparative Effectiveness (GRACE) Checklist. Investigators evaluated 565 references cited in 27 monographs/therapeutic class reviews from 6 managed care organizations. Therapeutic class reviews mostly cited published clinical trials (35.3%, 155/439), while single-product monographs relied most on manufacturer-supplied information (42.1%, 53/126). Published RWE comprised 4.8% (21/439) of therapeutic class review references, and none (0/126) of the monograph references. Of the 21 RWE studies, 12 were comparative and assessed patient care settings and outcomes typically not included in clinical trials (community ambulatory settings [10], long-term safety [8]). RWE studies most frequently were based on registry data (6), conducted in the United States (6), and funded by the pharmaceutical industry (5). GRACE Checklist ratings suggested the data and methods of these comparative RWE studies were of high quality. RWE was infrequently cited in P&T materials, even among therapeutic class reviews where RWE is more readily available. Although few P&T materials cited RWE, the comparative RWE studies were generally high quality. More research is needed to understand when and what types of real-world studies can more routinely inform coverage and reimbursement decisions. This project was funded by the National Pharmaceutical Council. Hurwitz, Brown, Peters, and Malone have nothing to disclose.

    While it is known that more women than men use complementary and alternative therapies, it is important to look at women who are pregnant or possibly receiving hormonal therapy, as side effects and consequences of these therapies may have a significant effect on their health status. To assess women's knowledge, perceived effectiveness and use of 20 complementary and alternative therapies. Descriptive four-page questionnaire to obtain data on the use, reason for use, knowledge, perceived effectiveness, and sources of information of twenty complementary and alternative therapies. Women's Health Center at a large Midwestern hospital. A convenience sample of 250 women waiting to be seen by either a nurse midwife or obstetrician/gynecologist at an outpatient clinic. Sixty-nine percent of the participants used one or more complementary therapy. The most frequently used therapies included prayer, vitamins, massage, diet, and aromatherapy. The best predictor of use of each therapy was the participant's knowledge of the therapy. Participants generally rated the efficacy of the therapies higher than their knowledge level. Frequently cited sources of information were popular media and family. The least common information sources were nurse-midwives, drug stores, Internet, and other professional healthcare providers. Women in this setting use complementary therapies at a rate greater than the general population. The participants obtained a great deal of their information about the therapies from popular press, media, friends, and family members rather than from licensed healthcare providers.

  2. Which early works are cited most frequently in climate change research literature? A bibliometric approach based on Reference Publication Year Spectroscopy.

    This bibliometric analysis focuses on the general history of climate change research and, more specifically, on the discovery of the greenhouse effect. First, the Reference Publication Year Spectroscopy (RPYS) is applied to a large publication set on climate change of 222,060 papers published between 1980 and 2014. The references cited therein were extracted and analyzed with regard to publications, which are cited most frequently. Second, a new method for establishing a more subject-specific publication set for applying RPYS (based on the co-citations of a marker reference) is proposed (RPYS-CO). The RPYS of the climate change literature focuses on the history of climate change research in total. We identified 35 highly-cited publications across all disciplines, which include fundamental early scientific works of the nineteenth century (with a weak connection to climate change) and some cornerstones of science with a stronger connection to climate change. By using the Arrhenius (Philos Mag J Sci Ser 5(41):237-276, 1896) paper as a RPYS-CO marker paper, we selected only publications specifically discussing the discovery of the greenhouse effect and the role of carbon dioxide. Using different RPYS approaches in this study, we were able to identify the complete range of works of the celebrated icons as well as many less known works relevant for the history of climate change research. The analyses confirmed the potential of the RPYS method for historical studies: Seminal papers are detected on the basis of the references cited by the overall community without any further assumptions.

    All U. S. Air Carrier accidents between 1963 and 1974 were studied to assess the extent of total personnel and aircraft damage which occurred in accidents and in accidents involving fire. Published accident reports and NTSB investigators' factual backup files were the primary sources of data. Although it was frequently not possible to assess the relative extent of fire-caused damage versus impact damage using the available data, the study established upper and lower bounds for deaths and damage due specifically to fire. In 12 years there were 122 accidents which involved airframe fires. Eighty-seven percent of the fires occurred after impact, and fuel leakage from ruptured tanks or severed lines was the most frequently cited cause. A cost analysis was performed for 300 serious accidents, including 92 serious accidents which involved fire. Personal injury costs were outside the scope of the cost analysis, but data on personnel injury judgements as well as settlements received from the CAB are included for reference.

    The aim of this study was to use journal metrics to confirm that the Journal of Exercise Rehabilitation has been promoted to the international level after changing its language to English-only in April 2013. Journal metrics, including the number of articles per year, countries of authors, countries of the editorial board members, impact factor, total citations, and the Hirsch index, were counted or calculated based on the journal homepage and the Web of Science Core Collection in December 2016. The number of citable articles was 52, 62, 59, and 74 in 2013, 2014, 2015, and 2016, respectively. All authors were from Korea in 2013 and 2014, but the authors were from 11 countries in 2015 and from 16 countries in 2016. The editorial board members are currently from 11 countries. The impact factor without self-citations for 2015 was 0.912, corresponding to a Journal Citation Reports ranking of 32.9% out of 82 journals in the category of sport sciences. The total citations increased from 1 in 2013 to 130 in 2016. This journal was cited in 208 other source journals in the Web of Science. The citing authors were from 47 countries. The Hirsch index was 7, and review articles were the most frequently cited articles. The above results show a rapid development to the international level over 4 years. The introduction of digital technology to journals to improve their accessibility across multiple platforms is recommended.

    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.

    There is an abundance of articles published on meningioma. To identify the 100 most-cited articles on meningioma and to perform a bibliometric analysis. In November 2016, we performed a title-specific search of the Scopus database using "meningioma" as our search query term without publication date restrictions. The top 100 most cited articles were obtained and reviewed. The top 100 most cited articles received a mean 198 citations per paper. Publication dates ranged from 1953 to 2013; most articles were published between 1994 and 2003, with 50 articles published during that period. NEUROSURGERY published the greatest number of top cited articles (22 of 100). The most frequent study categories were laboratorial studies (31 of 100) and natural history studies (28 of 100). Nonoperative management studies were twice as common as operative management studies in the top-cited articles. Neurosurgery as a specialty contributed to 50% of the top 100 list. The most contributing institute was the Mayo Clinic (11%); the majority of the top cited articles originated in the United States (53%). We identified the top 100 most-cited articles on meningioma that may be considered significant and impactful works, as well as the most noteworthy. In addition, we recognized the historical development and advances in meningioma research and the important contributions of various authors, specialty fields, and countries. A large proportion of the most cited articles were written by authors other than neurosurgeons, and many of these articles were published in non-neurosurgery journals. Copyright © 2017 Elsevier Inc.

  7. Methodological rigor and citation frequency in patient compliance literature.

    1982-01-01

    An exhaustive bibliography which assesses the methodological rigor of the patient compliance literature, and citation data from the Science Citation Index (SCI) are combined to determine if methodologically rigorous papers are used with greater frequency than substandard articles by compliance investigators. There are low, but statistically significant, correlations between methodological rigor and citation indicators for 138 patient compliance papers published in SCI source journals during 1975 and 1976. The correlation is not strong enough to warrant use of citation measures as indicators of rigor on a paper-by-paper basis. The data do suggest that citation measures might be developed as crude indicators of methodological rigor. There is no evidence that randomized trials are cited more frequently than studies that employ other experimental designs. PMID:7114334

    2008-03-01

    Commercialization of genetic technologies is expanding the horizons for the marketing and sales of genetic tests direct-to-consumers (DTCs). This study assesses the information provision and access requirements that are in place for genetic tests that are being advertised DTC over the Internet. Sets of key words specific to DTC genetic testing were entered into popular Internet search engines to generate a list of 24 companies engaging in DTC advertising. Company requirements for physician mediation, genetic counseling arrangements, and information provision were coded to develop categories for quantitative analysis within each variable. Results showed that companies offering risk assessment and diagnostic testing were most likely to require that testing be mediated by a clinician, and to recommend physician-arranged counseling. Companies offering enhancement testing were less likely to require physician mediation of services and more likely to provide long-distance genetic counseling. DTC advertisements often provided information on disease etiology; this was most common in the case of multifactorial diseases. The majority of companies cited outside sources to support the validity of claims about clinical utility of the tests being advertised; companies offering risk assessment tests most frequently cited all information sources. DTC advertising for genetic tests that lack independent professional oversight raises troubling questions about appropriate use and interpretation of these tests by consumers and carries implications for the standards of patient care. These implications are discussed in the context of a public healthcare system.

    This paper aims to track smokers' and recent quitters' recall of tobacco news, compare patterns of recall with patterns of news coverage and assess associations between news recall and smoking-related cognitions and behaviours, by using a quantitative analysis. The Cancer Institute New South Wales (NSW)'s Tobacco Tracking Survey, a continuous tracking telephone survey of adult smokers and recent quitters, was used to monitor recall of tobacco news and smoking-related cognitions and behaviours from January to September 2010 (approximately 50 interviews per week; n = 1952). Thirty per cent of respondents reported semi-prompted recall of tobacco news with patterns of recall closely following peaks in news coverage. Television was the most frequently cited source of tobacco news. Multivariate logistic regression analyses indicated that, controlling for individual characteristics, smokers with high levels of tobacco news recall were significantly more likely to have strong beliefs about harms from smoking [odds ratio (OR) = 1.38] and frequent thoughts about quitting (OR = 1.32). The results show that the news media are an important source of information for smokers, with the potential to influence beliefs and to put or keep quitting on the smokers' agenda. Media advocacy remains an important component of tobacco control.

    The aim of this study was to ascertain farmers' knowledge of the risk of spread of infection from animals to humans, and their transmission prevention practices. This was a survey of farmers who submitted material to Ireland's Regional Veterinary Laboratories in 2015. There was an 84% response rate (1044 farmers). Ninety per cent of farmers were not aware that infection can be acquired from apparently healthy animals. Over half were not aware that disease could be contracted from sick poultry or pets. Conversely, the knowledge of the risk to pregnant women of infection from birthing animals was high (88%). Four-fifths of farmers sourced drinking water from a private well, and of these, 62% tested their water less frequently than once a year. Of dairy farmers, 39% drank unpasteurised milk once a week or more frequently. Veterinarians were the most commonly cited information source for diseases on farms. The survey findings indicate that the level of farmers' knowledge and awareness of the spread of infection from animals to humans is a concern. Further education of the farming community is needed to increase awareness of both the potential biohazards present on farms and the practical measures that can be taken to mitigate the risk of zoonoses.

    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

    To assess the frequency and evaluate the factors underlining self-medication with orthodox and herbal medicines among pregnant women in Ibadan, Nigeria. Setting Antenatal clinics at the major antenatal care facility in Ibadan, south-western Nigeria. A prospective cross-sectional study with a pre-tested 15-item structured questionnaire over a 12 week period among 1,650 pregnant women who attended antenatal clinics at a major antenatal care facility in Ibadan, south-western Nigeria. Data analysis was done with Chi-square, multivariate logistic regression and summary statistics. Frequency and major factors associated with self-medication in pregnancy. The response and completion rate was 96.6% (1,594) [mean age ± SD 27 ± 5.3 years]. The majority of the respondents were literate (92.6%), self-employed (61.5%) and in the third trimester (49.5%). A significant majority (63.8%) used self-medication (orthodox and herbal medicines) as their first response to perceived ill-health (P < 0.001). Self-medication in pregnancy was strongly associated with self-employment (OR: 3.8 (2.6-4.7), unemployment (OR: 2.6 (1.4-4.2) and third trimester of pregnancy (OR: 4.2 (3.1-5.6). The major over-the-counter medicines and potentially harmful prescription medicines kept at home for self-medication were Paracetamol, vitamins and haematinics; and piroxicam, dipyrone, chloramphenicol and Diazepam respectively. About one-third of the respondents who self-medicated (1,017) used local herbs (31.2%). The most frequent source of the medicines purchased during self-medication was patent medicine stores (55%). Mothers-in-law and relatives (41.3%) were the most frequently cited sources of advice during self-medication. Miscarriage/bleeding (44.3%) was the most frequently cited potential adverse effect that could occur with the use of certain medicines during pregnancy. Only 32% of respondents could identify medicines that are potentially harmful in pregnancy. Poorly guided self-medication with prescription, over-the-counter and herbal medicines is pervasive and significantly associated with gestational age and occupational pattern among pregnant women in Ibadan, south-western. A majority lacked the knowledge of potential adverse outcomes associated with the use of certain medicines, and the potentially harmful medicines to avoid during pregnancy.

  15. [Citation rates of medical German-language journals in English-language papers - do they correlate with the Impact Factor, and who cites?].

    Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected >85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our > constructed< IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r <0.1). 64 % of citing English-language articles showed corporate sources in Germany/ Austria/ Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/=1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/ EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

  16. Environmental news: coverage of the Earth Summit by Brazilian newspapers.

    Reis, R

    1999-12-01

    This article examines how two important Brazilian newspapers (Floha de S. Paulo and O Globo) covered the UN Conference on Environment and Development (UNCED) or Earth Summit. The analysis will also determine the characteristics of the environmental media and its significance when it comes to coverage of environmental issues. This article provides historical background information on the environmental media in the US and in Brazil, contextual information on the Earth Summit, a content analysis of stories about UNCED published by the two Brazilian newspapers. Overall, 649 news items were used to determine the type of sources used, as well as the kind of issues covered. The analysis showed that government officials were the most frequently cited sources, while environmentalists and scientists were all but ignored as news sources. The analysis also indicated that economic issues were surprisingly prominent in the coverage. These results are compatible with the previous studies done in several countries and indicate that environmental media are still extremely reliant on "official" voices. The finding also highlight the fact that the range of issues covered by the environmental media largely reflects the perceived public agenda.

    To identify and assess the research situation of top 100 cited articles in nonalcoholic fatty liver disease (NAFLD). The global scientific research articles in the Science Citation Index-Expanded relevant to NAFLD were retrieved and listed according to their citation times from the most to the least. The 100 most frequently cited original articles were selected to systematically evaluate their bibliometric parameters including times cited, publication year, journals, subject categories, and the highly related concepts of NAFLD, which reflected the history and current situation, publication distribution of leading countries and institutes as well as the research hotspots of NAFLD. Top 100 cited articles in NAFLD were published from 1965 to 2015 with a citation ranging of 227 to 2151 times since publication, in which the United States was the most predominant country and Mayo Clin was the most productive institution. The majority of the top 100 cited articles were concentrated in SCI subject category of Gastroenterology and Hepatology. Hepatology and Gastroenterology is the top journal that published over half 100 top-cited articles. The significant peak of top cited articles present in the first half of the 2000s while the highest mean number of citation presents in first half of the 1980s. In addition, concepts related to pathology characteristics, epidemiology and medicalization, metabolic syndrome and its combination of symptoms including insulin resistance, biomarkers of lipid metabolism and obesity are listed as the highly related concepts. The 100 top-cited articles marked with the leading countries, institutions, journals, hotspots and development trend in NAFLD field that could provide the foundation for further investigations.

    The number of citations that papers receive has become significant in measuring researchers' scientific productivity, and such measurements are important when one seeks career opportunities and research funding. Skewed citation practices can thus have profound effects on academic careers. We investigated (i) how frequently authors misinterpret original information and (ii) how frequently authors inappropriately cite reviews instead of the articles upon which the reviews are based. To reach this aim, we carried a survey of ecology journals indexed in the Web of Science and assessed the appropriateness of citations of review papers. Reviews were significantly more often cited than regular articles. In addition, 22% of citations were inaccurate, and another 15% unfairly gave credit to the review authors for other scientists' ideas. These practices should be stopped, mainly through more open discussion among mentors, researchers and students. PMID:24349143

    Bibliometric analysis is the application of statistical methods to analyze quantitative data about scientific publications. It can evaluate research performance, author productivity, and manuscript impact. To the best of our knowledge, no bibliometric analysis has focused on cardiac computed tomography (CT). The purpose of this paper was to compile a list of the 100 most-cited articles related to cardiac CT literature using Scopus and Web of Science (WOS). A list of the 100 most-cited articles was compiled by order of citation frequency, as well a list of the top 10 most-cited guideline and review articles and the 20 most-cited articles of the years 2014-2015. The database of 100 most-cited articles was analyzed to identify characteristics of highly cited publications. For each manuscript, the number of authors, study design, size of patient cohort and departmental affiliations were cataloged. The 100 most-cited articles were published from 1990 to 2012, with the majority (53) published between 2005 and 2009. The total number of citations varied from 3354 to 196, and the number of citations per year varied from 9.5 to 129.0 with a median and mean of 30.9 and 38.7, respectively. The majority of publications had a study patients sample size of 200 patients or less. The USA and Germany were the nations with the highest number of frequently cited publications. This bibliometric analysis provides insights on the most-cited articles published on the subject of cardiac CT and calcium volume, thus helping to characterize the field and guide future research.

    Scientometric data on the citation success of different publication types and publication genres in psychology publications are presented. Data refer to references that are cited in these scientific publications and that are documented in PSYNDEX, the exhaustive database of psychology publications from the German-speaking countries either published in German or in English language. Firstly, data analyses refer to the references that are cited in publications of 2009 versus 2010 versus 2011. With reference to all cited references, the portion of journal articles ranges from 57 to 61 %, of books from 22 to 24 %, and of book chapters from 14 to 15 %, with a rather high stability across the three publication years analysed. Secondly, data analyses refer to the numbers of cited references from the German-speaking countries, which are also documented in PSYNDEX. These compose about 11 % of all cited references indicating that nearly 90 % of the references cited are of international and/or interdisciplinary publications not stemming from the German-speaking countries. The subsample shows the proportion of journal articles, books, and chapters, and these are very similar to the percentages identified for all references that are cited. Thirdly, analyses refer to document type, scientific genre, and psychological sub-discipline of the most frequently cited references in the psychology publications. The frequency of top-cited references of books and book chapters is almost equal to that of journal articles; two-thirds of the top-cited references are non-empirical publications, only one-third are empirical publications. Top-cited references stem particularly from clinical psychology, experimental psychology, as well as tests, testing and psychometrics. In summary, the results point to the fact that citation analyses, which are limited to journal papers, tend to neglect very high portions of references that are cited in scientific publications.

    Cancer is the leading cause of morbidity and mortality worldwide, characterized by irregular cell growth. Cytotoxicity or killing tumor cells that divide rapidly is the basic function of chemotherapeutic drugs. However, these agents can damage normal dividing cells, leading to adverse effects in the body. In view of great advances in cancer therapy, which are increasingly reported each year, we quantitatively and qualitatively evaluated the papers published between 1981 and December 2015, with a closer look at the highly cited papers (HCPs), for a better understanding of literature related to cytotoxicity in cancer therapy. Online documents in the Web of Science (WOS) database were analyzed based on the publication year, the number of times they were cited, research area, source, language, document type, countries, organizationenhanced and funding agencies. A total of 3,473 publications relevant to the target key words were found in the WOS database over 35 years and 86% of them (n=2,993) were published between 20002015. These papers had been cited 54,330 times without self citation from 1981 to 2015. Of the 3,473 publications, 17 (3,557citations) were the most frequently cited ones between 2005 and 2015. The topmost HCP was about generating a comprehensive preclinical database (CCLE) with 825 (23.2%) citations. One third of the remaining HCPs had focused on drug discovery through improving conventional therapeutic agents such as metformin and ginseng. Another 33% of the HCPs concerned engineered nanoparticles (NPs) such as polyamidoamine (PAMAM) dendritic polymers, PTX/SPIOloaded PLGAs and cell derived NPs to increase drug effectiveness and decrease drug toxicity in cancer therapy. The remaining HCPs reported novel factors such as miR205, Nrf2 and p27 suggesting their interference with development of cancer in targeted cancer therapy. In conclusion, analysis of 35year publications and HCPs on cytotoxicity in cancer in the present report provides opportunities for a better understanding the extent of topics published and may help future research in this area.

    Vesicoureteral reflux (VUR) has been one of the defining conditions unique to pediatric urology since its inception. The clinical implications of this disease process depend on intrinsic patient factors such as age, genetics, epigenetics, voiding habits, anatomic anomalies, and extrinsic factors such as the pathogenicity of infectious agents. Knowledge about its natural history, the implications of conservative and surgical management, and their associated outcomes have evolved dramatically over time. This study aimed to use bibliometric analyses to summarize the evolution of VUR management over time. In order to accomplish this, the most referenced articles for VUR since 1950 were identified, and a comprehensive analysis of their impact on the management and understanding of VUR was performed by creating a novel impact index. A reference search was carried out for indexed citations through the portal 'Science Citation Index' in the subsection 'Web of Science Core Collection' using 'vesicoureteral reflux' as a MeSH term. References were analyzed and subcategorized according to various subtopics. A unique impact index was developed to adjust the number of publications for the time since publication, in order to define the impact of the paper amongst the most frequently cited papers. Articles were analyzed and data were tabulated according to the number of citations, country and institute of origin, journal of publication, impact factor, and first authorship. Citation counts ranged from 43 to 510, and the mean number of citations per publication was 101.43. The most discussed topic was 'treatment'. The impact index showed that more recent publications have a higher impact. The author with the highest index impact had 271 citations in a period of 5 years. The top 150 articles were published across 23 countries, the majority being from the USA (Summary fig.). The most frequently cited institution had 12 publications. The journal with the highest publication referencing rate was the Journal of Urology. The most cited articles were valuable sources of information to describe the historical evolution of the pathophysiology and management of VUR. After adjusting for time since publication, the most recent publications (i.e. those published after 1990) had a higher impact index. Combining traditional bibliometric analysis with this novel impact index may allow researchers to optimize future literature analyses, while also assisting clinicians in understanding best practices for patient management based on the available literature.

    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.

    The purpose of this study was to identify and characterize the most-cited articles on headache disorders published in journals that have made key contributions in the field. We performed a search of journals and selected the top-100 cited articles by utilizing the Institute for Scientific Information database available under the banner of the Web of Science, which provides the most relevant bibliometric information on scientific articles published since 1950. The top-100 cited articles were published in 20 journals. The most frequently cited journal was Neurology (19 articles), and followed by Cephalagia (15 articles) and Headache (15 articles). Migraine was the most common topic subject (81 articles), and original articles predominated (91 articles). The topics of the classic articles had varied from decade to decade. The most common topic subject was epidemiology (37 articles), followed by pathophysiology (20 articles), treatment (18 articles), review (10 articles), neuroimaging (11 articles), genetics (3 articles), and diagnostic tools (2 articles). The present study has produced a detailed list of the most-cited articles on headache disorders, which is the first such study in this field. This list makes it possible to recognize the classic articles on headache disorders as well as research trends and academic achievements in this field. Copyright © 2017. Published by Elsevier B.V.

    This study analyzes and compares the science and technology coverage in Brazil's main television news program (Jornal Nacional) and its Colombian counterpart (Noticias Caracol). Using content analysis, we investigated a corpus of news stories broadcast from April 2009 to March 2010. We found that Jornal Nacional presented over twice as many reports on science and technology as Noticias Caracol, and that its levels of reporting remained fairly stable throughout the year. The Brazilian reports were also longer, were featured more prominently, and used more visual resources. Even so, some similarities were found: news about health and medicine was most frequent; the reports focused primarily on announcing new research; scientists were the main sources cited; and national research was prioritized.

    Marriage and family services have not been widely recognized as part of employee assistance programs (EAP), although family and relational problems are widely cited as sources of problems on the job. EAP clients (N = 800, 97% self-referred) indicated how much family, psychological/emotional, drug, alcohol, employment-related, legal, and medical problems troubled them and the need for services in each area. Psychological/emotional (66%) and family (65%) problem areas frequently were rated "considerable" or "extreme." Both areas were rated as "considerable" or "extreme" by 48.6% of participants. In view of the evidence that marriage and family services can be effective with both family and psychological/emotional problems, professionals who are competent to provide such services have much to offer EAP programs.

    This paper describes a citation analysis of the literature of clinical laboratory science (medical technology), conducted as part of a project of the Nursing and Allied Health Resources Section of the Medical Library Association. Three source journals widely read by those in the field were identified, from which cited references were collected for a three-year period. Analysis of the references showed that journals were the predominant format of literature cited and the majority of the references were from the last eleven years. Applying Bradford's Law of Scattering to the list of journals cited, three zones were created, each producing approximately one third of the cited references. Thirteen journals were in the first zone, eighty-one in the second, and 849 in the third. A similar list of journals cited was created for four specialty areas in the field: chemistry, hematology, immunohematology, and microbiology. In comparing the indexing coverage of the Zone 1 and 2 journals by four major databases, MEDLINE provided the most comprehensive coverage, while the Cumulative Index to Nursing and Allied Health Literature was the only database that provided complete coverage of the three source journals. However, to obtain complete coverage of the field, it is essential to search multiple databases.

    At the end of the 20th century, access to information provided by the World Wide Web (WWW) is changing as never before. The fast availability of current medical literature and the availability of tools for easy access to information, as well as for the easy production of information, have confronted research physicians, scholars, and students with new kinds of problems, many of which concern us personally. Quality control, difficulty establishing basic citation components, lack of standard guidelines for citing, as well as the short lifetime of Internet addresses concern us deeply. Some of these problems could be solved by the concept of an “Online-Library of Medicine” presented in the following paper. Since, however, at the present time there are no good answers to the problems regarding citing Internet-based sources, a Web surfer must keep in his or her mind the motto “caveat lector” (let the reader beware) - or, rather, in the spirit of our time: click c@refully before you cite.

    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. We conducted 16 semi-structured interviews and one focus group with individuals involved in WTMS at the federal, provincial or organizational level. 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. 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.

  16. Tracing the indirect societal impacts of biomedical research: development and piloting of a technique based on citations.

    Jones, Teresa H; Hanney, Steve

    There is growing interest in assessing the societal impacts of research such as informing health policies and clinical practice, and contributing to improved health. Bibliometric approaches have long been used to assess knowledge outputs, but can they also help evaluate societal impacts? We aimed to see how far the societal impacts could be traced by identifying key research articles in the psychiatry/neuroscience area and exploring their societal impact through analysing several generations of citing papers. Informed by a literature review of citation categorisation, we developed a prototype template to qualitatively assess a reference's importance to the citing paper and tested it on 96 papers. We refined the template for a pilot study to assess the importance of citations, including self-cites, to four key research articles. We then similarly assessed citations to those citing papers for which the key article was Central i.e. it was very important to the message of the citing article. We applied a filter of three or more citation occasions in order to focus on the citing articles where the reference was most likely to be Central. We found the reference was Central for 4.4 % of citing research articles overall and ten times more frequently if the article contained three or more citation occasions. We created a citation stream of influence for each key paper across up to five generations of citations. We searched the Web of Science for citations to all Central papers and identified societal impacts, including international clinical guidelines citing papers across the generations.

  17. Effect of medicolegal liability on patterns of general and family practice in Canada.

    1989-01-01

    As part of the Federal/Provincial/Territorial Review on Liability and Compensation Issues in Health Care, in 1988 we surveyed Canadian general practitioners and family physicians to determine the effect of liability concerns on their practices in the previous 5 years. Questionnaires were sent to a random, stratified national sample of 1295 physicians, with a response rate of 64.6%. However, a high proportion of the returned questionnaires were ineligible because the physicians were not in general or family practice, were not involved in direct patient care, or had died or moved; thus, the corrected response rate was 50.8%. The newsletter of the Canadian Medical Protective Association was the source of information on liability most frequently cited (by 88.1% of the physicians) and most influential (to 62.4%). Only 15.5% of the physicians cited personal involvement with medicolegal issues as a source of information; the rate was higher for Ontario physicians and those in urban areas generally. A total of 74.6% of the respondents had altered their style of practice in the previous 5 years, and 56.3% reported changes in the scope of their practice. Concern about litigation was the most important reason for changing style of practice and reducing or eliminating administration of anesthesia, whereas lifestyle and other issues along with liability concerns most influenced decisions to reduce obstetric care and emergency department work. Our findings suggest that physicians' perceptions of liability issues have had a profound influence on primary care practice in Canada in the past several years. PMID:2766164

  18. Ozone precursors and ozone photochemistry over eastern North Pacific during the spring of 1984 based on the NASA GTE/CITE 1 airborne observations

    1989-01-01

    Simultaneous high-resolution measurements of O3, NO, CO, dew point temperature, and UV flux obtained during the NASA Global Tropospheric Experiment Chemical Instrumentation Test and Evaluation (GTE/CITE 1) spring 1984 airborne field exercise over the eastern North Pacific Ocean are analyzed. Mid-tropospheric CO, O3, and NO mixing ratios averaged about 120 parts per billion by volume (ppbv), 50 ppbv, and 10 parts per trillion by volume (pptv), respectively. Statistical analysis of the high-resolution data indicates the existence of two ozone sources, one related to the downward transport of ozone-rich air from the upper troposphere and stratosphere, and the other to the transport of ozone-rich air from the continents. Modeling calculations based on these average levels imply that, from the surface to about 8 km, photochemical reactions probably supplied a net sink of ozone to the region overlying the eastern North Pacific Ocean during the sampling period. However, because the NO levels measured during the flights were frequently at or near the detection limit of the instruments and because the results are very sensitive to the absolute NO levels and their temporal variability, the conclusion must be considered provisional.

    2017-01-01

    The reasons for using electronic nicotine delivery systems (ENDS) are poorly understood and are primarily documented by expensive cross-sectional surveys that use preconceived close-ended response options rather than allowing respondents to use their own words. We passively identify the reasons for using ENDS longitudinally from a content analysis of public postings on Twitter. All English language public tweets including several ENDS terms (e.g., “e-cigarette” or “vape”) were captured from the Twitter data stream during 2012 and 2015. After excluding spam, advertisements, and retweets, posts indicating a rationale for vaping were retained. The specific reasons for vaping were then inferred based on a supervised content analysis using annotators from Amazon’s Mechanical Turk. During 2012 quitting combustibles was the most cited reason for using ENDS with 43% (95%CI 39–48) of all reason-related tweets cited quitting combustibles, e.g., “I couldn’t quit till I tried ecigs,” eclipsing the second most cited reason by more than double. Other frequently cited reasons in 2012 included ENDS’s social image (21%; 95%CI 18–25), use indoors (14%; 95%CI 11–17), flavors (14%; 95%CI 11–17), safety relative to combustibles (9%; 95%CI 7–11), cost (3%; 95%CI 2–5) and favorable odor (2%; 95%CI 1–3). By 2015 the reasons for using ENDS cited on Twitter had shifted. Both quitting combustibles and use indoors significantly declined in mentions to 29% (95%CI 24–33) and 12% (95%CI 9–16), respectively. At the same time, social image increased to 37% (95%CI 32–43) and lack of odor increased to 5% (95%CI 2–5), the former leading all cited reasons in 2015. Our data suggest the reasons people vape are shifting away from cessation and toward social image. The data also show how the ENDS market is responsive to a changing policy landscape. For instance, smoking indoors was less frequently cited in 2015 as indoor smoking restrictions became more common. Because the data and analytic approach are scalable, adoption of our strategies in the field can inform follow-up survey-based surveillance (so the right questions are asked), interventions, and policies for ENDS.

    The reasons for using electronic nicotine delivery systems (ENDS) are poorly understood and are primarily documented by expensive cross-sectional surveys that use preconceived close-ended response options rather than allowing respondents to use their own words. We passively identify the reasons for using ENDS longitudinally from a content analysis of public postings on Twitter. All English language public tweets including several ENDS terms (e.g., "e-cigarette" or "vape") were captured from the Twitter data stream during 2012 and 2015. After excluding spam, advertisements, and retweets, posts indicating a rationale for vaping were retained. The specific reasons for vaping were then inferred based on a supervised content analysis using annotators from Amazon's Mechanical Turk. During 2012 quitting combustibles was the most cited reason for using ENDS with 43% (95%CI 39-48) of all reason-related tweets cited quitting combustibles, e.g., "I couldn't quit till I tried ecigs," eclipsing the second most cited reason by more than double. Other frequently cited reasons in 2012 included ENDS's social image (21%; 95%CI 18-25), use indoors (14%; 95%CI 11-17), flavors (14%; 95%CI 11-17), safety relative to combustibles (9%; 95%CI 7-11), cost (3%; 95%CI 2-5) and favorable odor (2%; 95%CI 1-3). By 2015 the reasons for using ENDS cited on Twitter had shifted. Both quitting combustibles and use indoors significantly declined in mentions to 29% (95%CI 24-33) and 12% (95%CI 9-16), respectively. At the same time, social image increased to 37% (95%CI 32-43) and lack of odor increased to 5% (95%CI 2-5), the former leading all cited reasons in 2015.

For instance, smoking indoors was less frequently cited in 2015 as indoor smoking restrictions became more common. Because the data and analytic approach are scalable, adoption of our strategies in the field can inform follow-up survey-based surveillance (so the right questions are asked), interventions, and policies for ENDS.

    Citation analysis was performed in order to identify the top 50 most cited articles pertaining to the field of primary spinal tumors. This collection of articles highlights important trends in the neurosurgical literature. We searched the Thomson Reuters Web of Knowledge in order to identify articles pertaining to primary tumors of the spine. Impertinent articles were removed. The top 50 most cited articles were identified. Thereafter, article characteristics were determined including article type, article topic, level of evidence, and citation rate. The selected articles were published between 1951 and 2008. The most productive year was 1997 with 6 publications. The top 50 articles were published in twenty-two different journals, most commonly in Neurosurgery (12), Journal of Neurosurgery (8), and Spine (6). The most frequently cited article was by Tomita et al. written in 1997 which described total en bloc spondylectomy as a novel surgical technique in management of primary tumors of the vertebral column. We identified the 50 most-cited articles in the field of primary spinal tumors. This collection of articles serves as a reference for recognizing impactful studies in the field. Copyright © 2017.

    Abstract Aims To establish how frequently different types of stakeholders were cited in the UK media debate about e‐cigarette regulation, their stances towards different forms of e‐cigarette regulation, and what rationales they employed in justifying those stances. Methods Quantitative and qualitative content analyses of 104 articles about e‐cigarette regulation published in eight UK and three Scottish national newspapers between 1 January 2013 and 31 December 2014. Results Reporting on e‐cigarette regulation grew significantly (P < 0.001) throughout the sample period. Governments and regulatory bodies were the most frequently cited stakeholders and uniformly supported regulation, while other stakeholders did not always support regulation. Arguments for e‐cigarette regulation greatly outnumbered arguments against regulation. Regulating purchasing age, restricting marketing and regulating e‐cigarettes as medicine were broadly supported, while stakeholders disagreed about prohibiting e‐cigarette use in enclosed public spaces. In rationalizing their stances, supporters of regulation cited child protection and concerns about the safety of e‐cigarette products, while opponents highlighted the potential of e‐cigarettes in tobacco cessation and questioned the evidence base associating e‐cigarette use with health harms. Conclusions In the UK between 2013 and 2014, governments and tobacco control advocates frequently commented on e‐cigarettes in UK‐wide and Scottish national newspapers. Almost all commentators supported e‐cigarette regulation, but there was disagreement about whether e‐cigarette use should be allowed in enclosed public spaces. This appeared to be linked to whether commentators emphasized the harms of vapour and concerns about renormalizing smoking or emphasized the role of e‐cigarettes as a smoking cessation aid.

  3. [Citation rates of medical German-language journals in English-language papers--do they correlate with the impact factor, and who cites? (reprint)].

    Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected > 85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our "constructed" IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r < 0.1). 64 % of citing English-language articles showed corporate sources in Germany/Austria/Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/= 1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

    Cooper, Richelle J.; Schriger, David L.

    2005-01-01

    Background The primary goal of pharmaceutical advertisements is to convince physicians to prescribe the manufacturer's product. We sought to determine what materials are cited in support of claims in pharmaceutical ads and medical research articles, and whether health care professionals seeking to verify the claims could obtain these references. Methods We reviewed 438 unique ads from the 1999 issues of 10 American medical journals, and a random sample of 400 references in medical research articles selected from the same journals. We classified references as journal article, data on file, meeting abstract or presentation, book or monograph, marketing report, prescribing information, government document or Internet site. We attempted to confirm or obtain each reference through library and Internet searches or by direct request from the manufacturer. The main outcome we sought to determine was the availability of the reference to a clinician. We also ascertained the source of funding for original research cited in the ads and the research articles. Results In the 438 ads with medical claims, 126 contained no references and 312 contained 721 unique references. Of these ad references, 55% (396/721) cited journal articles and 19% (135/721) cited data on file. In contrast, in the sample of research article references, 88% (351/400) cited journal articles and 8% (33/400) cited books. Overall, 84% of the citations from the ads were available: 98% of journal articles, 86% of books, 71% of meeting abstracts or presentations and 20% of data-on-file references. In all, 99% of the sample of research article references were available. We determined that 58% of the original research cited in the pharmaceutical ads was sponsored by or had an author affiliated with the product's manufacturer, as compared with 8% of the articles cited in the research articles. Interpretation Many pharmaceutical ads contain no references for medical claims. Although references to journal articles were usually obtainable, other published sources were not as easily acquired. The majority of unpublished data-on-file references were not available, and the majority of original research cited to substantiate claims in the pharmaceutical ads was funded by or had authors affiliated with the product's manufacturer.

    Purpose The purpose of this study is to perform a citation analysis on the most frequently cited articles in the topic of cervical spine surgery and report on the top 100 most cited publication in this topic. Methods We used the Thomson Reuters Web of Science to search citations of all articles from 1945 to 2015 relevant to cervical spine surgery and ranked them according to the number of citations. The 100 most cited articles that matched the search criteria were further analyzed by number of citations, first author, journal, year of publication, country and institution of origin. Results The top 100 cited articles in the topic of cervical spine surgery were published from 1952-2011. The number of citations ranged from 106 times for the 100th paper to 1206 times for the top paper. The decade of 1990-1999 saw the most publications. The Journal of Spine published the most articles, followed by Journal of Bone and Joint Surgery America. Investigators from America authored the most papers and The University of California contributed the most publications. Cervical spine fusion was the most common topic published with 36 papers, followed by surgical technique and trauma. Conclusion This article identifies the 100 most cited articles in cervical spine surgery. It has provided insight to the history and development in cervical spine surgery and many of which have shaped the way we practice today. PMID:28765803

    Scientific research is an essential aspect in the ongoing development of medical education and improved patient care. Dissemination of findings is a pivotal goal of any health research study. The number of citations that a published article receives is reflective of the importance that paper has on clinical practice. To date, it is unknown which journals are most frequently cited as influencing the management of pelvic trauma. The aim of this study was to identify the top 50 publications relating to the management of pelvic trauma. The database of the Science Citation Index of the Institute for Scientific Information (1945 to 2016) was reviewed to identify the 50 papers most commonly cited. A total of 1535 papers were included. Of these, 31 papers were cited over 100 times with the top 50 cited 69 times or more. The top 50 were subjected to further analysis to identify the authors and institutions involved. The majority of these publications originated in the USA, followed by Canada. The most cited paper is "pelvic ring fractures-should they be fixed", published by Tile in 1988. We have identified and analysed the publications that have contributed most to the assessment and management of pelvic trauma over the past 50 years. We have also identified the researchers and institutions which have most influenced the evidence-based approach currently employed in the management of pelvic trauma.

  11. Print media coverage of research on passive smoking

    OBJECTIVE—To assess the extent and content of newspaper and magazine coverage of research on passive smoking.
DESIGN—Content analysis of newspaper and magazine articles.
SUBJECTS—Articles reporting on passive smoking research published in newspapers (n = 180) or magazines (n = 92) between January 1981 and December 1994.
MAIN OUTCOME MEASURES—Numbers of articles, conclusions of articles, sources quoted, numbers and characteristics of research studies cited, presence of tobacco advertising.
RESULTS—The number of newspaper and magazine articles reporting on passive smoking research increased from four in 1981 to 57 in 1992 and 32 in 1994. Sixty-two per cent (168/272) of articles concluded that the research on passive smoking is controversial. Tobacco industry representatives were quoted significantly more often in newspaper articles (52%, 94/180) than magazine articles (12%, 11/92) (p<0.0001). Of 121 different research studies cited in the lay press articles, only 15 were from tobacco-industry sponsored projects or publications. In magazines, acceptance of tobacco industry advertising was associated with the conclusion that research on passive smoking is controversial (p<0.0001).
CONCLUSIONS—Although research on the harmful effects of passive smoking accumulated between 1981 and 1994, lay press coverage of the research maintained that the science was controversial. Few research studies were cited to support the industry's claim that passive smoking is not harmful to health. However, tobacco industry representatives who were critical of the research methods used to study the health effects of passive smoking were frequently quoted.

    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.

    Safe drinking water is a global challenge for rural populations dependent on unregulated water. A scoping review of research on human health risk assessments (HHRA) applied to this vulnerable population may be used to improve assessments applied by government and researchers. This review aims to summarize and describe the characteristics of HHRA methods, publications, and current literature gaps of HHRA studies on rural populations dependent on unregulated or unspecified drinking water. Peer-reviewed literature was systematically searched (January 2000 to May 2014) and identified at least one drinking water source as unregulated (21%) or unspecified (79%) in 100 studies. Only 7% of reviewed studies identified a rural community dependent on unregulated drinking water. Source water and hazards most frequently cited included groundwater (67%) and chemical water hazards (82%). Most HHRAs (86%) applied deterministic methods with 14% reporting probabilistic and stochastic methods. Publications increased over time with 57% set in Asia, and 47% of studies identified at least one literature gap in the areas of research, risk management, and community exposure. HHRAs applied to rural populations dependent on unregulated water are poorly represented in the literature even though almost half of the global population is rural.

  18. Correlated factors in amphibian decline: Exotic species and habitat change in western Washington

    Adams, Michael J.

    1999-01-01

    Amphibian declines may frequently be associated with multiple, correlated factors. In western North America, exotic species and hydrological changes are often correlated and are considered 2 of the greatest threats to freshwater systems. Bullfrog (Rana catesbeiana) introductions are frequently cited as a threat to lentic-breeding anurans native to western North America and are a suspected factor in the decline of red-legged frogs (Rana aurora) in California. Introduced fish and habitat change are cited less frequently but are equally viable hypotheses. I examined the relation among introduced species, habitat, and the distribution and abundance of red-legged frogs in western Washington. Red-legged frog occurrence in the Puget Lowlands was more closely associated with habitat structure and the presence of exotic fish than with the presence of bull-frogs. The spread of exotics is correlated with a shift toward greater permanence in wetland habitats regionally. Conservation of more ephemeral wetland habitats may have direct benefits for some native amphibians and may also reduce the threat of exotic fish and bullfrogs, both of which were associated with permanent wetlands. Research and conservation efforts for lowland anurans in the West should emphasize the complexities of multiple contributing factors to amphibian losses.

    The aim of this study was to identify and analyze the top 50 most cited articles in cartilage regeneration. The impact of a scientific journal can be gauged by the total number of citations it has accrued. The top 50 most cited articles involving cartilage regeneration represent the most quoted level of evidence among this new subspecialty. This study aims to identify and analyze the 50 most cited articles in cartilage regeneration. The Web of Science™ citation indexing service was utilized to determine the most frequently cited articles published after 1956 containing "cartilage regeneration" in the "topic" or "title." The 50 most cited articles were included. The number of citations, year of publication, country of article origin, article institution, journal of publication, publication format, and authorship were then calculated for each article. The span of citations ranged from 1287 to 203 citations, with a mean of 361.02 citations per article in question. The articles originated from 11 countries, with the United States contributing 34 articles, followed by Japan with 5 articles. The articles were distributed across 34 high-impact journals. Biomaterials was the journal with the highest number of publications (seven articles) followed by the Journal of Orthopaedic Research (three articles). Of the 50 articles, 2 were clinical observational studies, 47 concerned basic science, and 1 was review article. The most cited articles involving cartilage regeneration are detected in both experimental and clinical research fields. The high ratio of basic science to clinical articles reflects the infancy of this relatively new specialty and that further clinical research is required in this area.

    The purpose of this study is to identify the top 100-cited articles dedicated to epilepsy and status epilepticus published in journals from January, 1950 through February, 2016 that have made key contributions in the field. We performed a search of journals and selected the top 100-cited articles on epilepsy and status epilepticus, respectively, by utilizing the Institute for Scientific Information database available under the banner of the Web of Science. The top-cited articles on epilepsy and status epilepticus were all published in 24 journals, respectively. In both fields of epilepsy and status epilepticus, the most frequently cited journal was Epilepsia (26 articles on epilepsy and 19 articles on status epilepticus). The 100 most-cited articles in the field of both epilepsy and status epilepticus mainly originated from institutions in the United States of America. The articles on epilepsy included 25 laboratory studies, 15 pharmacotherapy studies, 13 general review studies, 12 surgery studies, 11 neuroimaging studies, eight epidemiology studies, eight neuropsychiatry studies, six genetic studies, and two electrophysiology studies, whereas 41 laboratory studies, 21 epidemiology studies, 16 pharmacotherapy studies, nine electrophysiology studies, nine general review studies, and four neuroimaging studies were included in the field of status epilepticus. We demonstrate that neuroimaging, genetics, and surgery are emerging topics in the field of epilepsy over the past decades. Moreover, we found that the majority of top-cited articles on epilepsy and status epilepticus originated from institutions in the United States of America and most were published in Epilepsia.

Using a mixed method case study approach with 34 agencies within one state we assessed administrators' perspectives of the most important funding source, treatment and services offered. We found that agencies rely on multiple funding sources and the source rated most important was associated with treatment and services offered in the agency. Those agencies citing a criminal justice entity as the most important funder were more likely to offer specific ancillary services and adopt motivational interviewing than those citing private funds. Although client characteristics or training opportunities may determine these services and practices, the agency's most important funding source may have implications for services offered.

    To examine the public health and policy-relevant messages conveyed through local television news during the first stage of Affordable Care Act (ACA) implementation, when about 10 million Americans gained insurance. We conducted a content analysis of 1569 ACA-related local evening television news stories, obtained from sampling local news aired between October 1, 2013, and April 19, 2014. Coders systematically collected data using a coding instrument tracking major messages and information sources cited in the news. Overall, only half of all ACA-related news coverage focused on health insurance products, whereas the remainder discussed political disagreements over the law. Major policy tools of the ACA-the Medicaid expansion and subsidies available-were cited in less than 10% of news stories. Number of enrollees (27%) and Web site glitches (33%) were more common features of coverage. Sources with a political affiliation were by far the most common source of information (> 40%), whereas research was cited in less than 4% of stories. The most common source of news for Americans provided little public health-relevant substance about the ACA during its early implementation, favoring political strategy in coverage.

    To compare Spanish nursing journals with 2 English-language standard journals, as well as Spanish journals in closely related disciplines, to identify possible quantitative and qualitative shortcomings in scientific documentation. We performed a descriptive, cross-sectional study of the references contained in 796 articles from 6 Spanish journals from 3 health disciplines (2000-2002) and 2 English-language nursing journals (2000-2001). The number of references, type of publication cited, and language of the document cited were compared in individual journals, and in journals grouped by discipline and according to language. Spanish-language nursing journals had the lowest mean number of references per article (X- = 16.20) when compared with psychology journals (X- = 31.24), medical journals (X- = 31.39) and international nursing journals (X- = 37.11). Among Spanish journals, citation of English-language publications was most frequent in medical journals (X- = 26.28) and least frequent in nursing journals (X- = 6.04). In contrast, citation of Spanish documents was most frequent in nursing journals (X- = 9.79) and least frequent in medical journals (X- = 4.43). Although scientific publication of Spanish nursing has improved, it is not comparable to publication of closely related disciplines and international nursing. The low citation of English documents clearly reveals the risk of scientific insularity.

  7. Who thinks what about e-cigarette regulation? A content analysis of UK newspapers.

    To establish how frequently different types of stakeholders were cited in the UK media debate about e-cigarette regulation, their stances towards different forms of e-cigarette regulation, and what rationales they employed in justifying those stances. Quantitative and qualitative content analyses of 104 articles about e-cigarette regulation published in eight UK and three Scottish national newspapers between 1 January 2013 and 31 December 2014. Reporting on e-cigarette regulation grew significantly (P < 0.001) throughout the sample period. Governments and regulatory bodies were the most frequently cited stakeholders and uniformly supported regulation, while other stakeholders did not always support regulation. Arguments for e-cigarette regulation greatly outnumbered arguments against regulation. Regulating purchasing age, restricting marketing and regulating e-cigarettes as medicine were broadly supported, while stakeholders disagreed about prohibiting e-cigarette use in enclosed public spaces. In rationalizing their stances, supporters of regulation cited child protection and concerns about the safety of e-cigarette products, while opponents highlighted the potential of e-cigarettes in tobacco cessation and questioned the evidence base associating e-cigarette use with health harms. In the UK between 2013 and 2014, governments and tobacco control advocates frequently commented on e-cigarettes in UK-wide and Scottish national newspapers. Almost all commentators supported e-cigarette regulation, but there was disagreement about whether e-cigarette use should be allowed in enclosed public spaces. This appeared to be linked to whether commentators emphasized the harms of vapour and concerns about renormalizing smoking or emphasized the role of e-cigarettes as a smoking cessation aid. © 2016 The Authors.

    Chordomas are rare malignant primary tumors of the spine. In the mobile spine and sacrum an en-bloc resection is associated with decreased rates of recurrence. Our objective was to identify the top cited articles in chordoma research and to further analyze characteristics of these articles. 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 review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

    To analyze the impact of articles published in English compared to those published in Spanish in multilingual Spanish biomedical journals. We analyzed the language of publication, the number of original articles, the nationality of the authors, the citations received, the citing article and the nationality of the citing authors among the articles published from 2008-2012 in 5 multilingual Spanish biomedical journals. The study included 4,296 documents, 85 of which were published in English (2%). The percentage of original articles and of non-Spanish authorship was significantly higher among these latter articles and they also achieved more citations and more citing articles per article published. The proportion of articles published in English by multilingual Spanish biomedical journals is low and they are more often originals signed exclusively by foreign authors and receive more citations than those published in Spanish, which are also more frequently made by foreign authors.

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

    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.

    The advancement of knowledge is based on the results of previously conducted research studies, which are reflected in the reference sources listed in a scientific article. This study is aimed at studying the scientific information used in the Revista Española de Salud Pública based on the references cited in the original articles published during the 1991-2000 period. The data regarding the year and where published, document type, language and country in which published was taken from the reference sources listed in the 290 original articles published, the obsolescence, Price and isolation indexes being calculated, and the Bradford core distribution being established according to the source journals. The self-citing rate was also calculated. A total of 7465 references were cited in the Reference section of the 290 original articles. An average of 25.7 references were cited per article. The Price index was 40.7. The scientific articles showed an obsolescence index of 5, the books and book chapters having an index of 6. A total 50.6% of the citations were from studies published in Spanish. The isolation index of the references was 48.1. The first Bradford core is comprised of 10 journals, the first four of which are Spanish. The self-citing rate was 3.8%. The information consumption of the original articles published in the Revista Española de Salud Pública show parameters similar to those of other Spanish health sciences journals for those same years, and the parameters regarding which this Journal differs from other Spanish health sciences journals seem to be justified by those particular aspects unique to public health, which does not fall within the patterns inherent to the clinical disciplines.

  15. Donating blood: a meta-analytic review of self-reported motivators and deterrents.

    2011-10-01

    Although research on blood donor motivation abounds, most studies have typically focused on small sets of variables, used different terminology to label equivalent constructs, and have not attempted to generalize findings beyond their individual settings. The current study sought to synthesize past findings into a unified taxonomy of blood donation drivers and deterrents and to estimate the prevalence of each factor across the worldwide population of donors and eligible nondonors. Primary studies were collected, and cross-validated categories of donation motivators and deterrents were developed. Proportions of first-time, repeat, lapsed, apheresis, and eligible nondonors endorsing each category were calculated. In terms of motivators, first-time and repeat donors most frequently cited convenience, prosocial motivation, and personal values; apheresis donors similarly cited the latter 2 motivators and money. Conversely, lapsed donors more often cited collection agency reputation, perceived need for donation, and marketing communication as motivators. In terms of deterrents, both donors and nondonors most frequently referred to low self-efficacy to donate, low involvement, inconvenience, absence of marketing communication, ineffective incentives, lack of knowledge about donating, negative service experiences, and fear. The integration of past findings has yielded a comprehensive taxonomy of factors influencing blood donation and has provided insight into the prevalence of each factor across multiple stages of donors' careers. Implications for collection agencies are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

    2016-07-01

    To examine the relationships between study quality, author prestige, journal impact factors, and citation rates of trials and to examine whether journal impact factors mediated the relationships between study quality and author prestige on citation rates. We used bibliometric data from 128 controlled trials included in a recent meta-analysis on brief alcohol interventions for adolescents and young adults. We obtained the number of citations from ISI Web of Knowledge and Google Scholar; journal impact factors were obtained from ISI Web of Knowledge. Linear regression models were used to examine the direct and indirect effects of interest. The results indicated that studies were published in journals with higher impact factors when first authors had higher h-indices and studies were funded, but this was largely because those studies were of higher quality. Studies were cited more frequently when first authors had higher h-indices and studies were funded, even after adjusting for study quality proxies. The observed associations between study quality and author prestige on citation rates were also partly mediated through journal impact factors. We conclude that studies conducted by more established authors and reported in more prestigious journal outlets are more likely to be cited by other scholars, even after controlling for various proxies of study quality.

    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.

  1. Information sources for obesity prevention policy research: a review of systematic reviews.

    Hanneke, Rosie; Young, Sabrina K

    2017-08-08

    Systematic identification of evidence in health policy can be time-consuming and challenging. This study examines three questions pertaining to systematic reviews on obesity prevention policy, in order to identify the most efficient search methods: (1) What percentage of the primary studies selected for inclusion in the reviews originated in scholarly as opposed to gray literature? (2) How much of the primary scholarly literature in this topic area is indexed in PubMed/MEDLINE? (3) Which databases index the greatest number of primary studies not indexed in PubMed, and are these databases searched consistently across systematic reviews? We identified systematic reviews on obesity prevention policy and explored their search methods and citations. We determined the percentage of scholarly vs. gray literature cited, the most frequently cited journals, and whether each primary study was indexed in PubMed. We searched 21 databases for all primary study articles not indexed in PubMed to determine which database(s) indexed the highest number of these relevant articles. In total, 21 systematic reviews were identified. Ten of the 21 systematic reviews reported searching gray literature, and 12 reviews ultimately included gray literature in their analyses. Scholarly articles accounted for 577 of the 649 total primary study papers. Of these, 495 (76%) were indexed in PubMed. Google Scholar retrieved the highest number of the remaining 82 non-PubMed scholarly articles, followed by Scopus and EconLit. The Journal of the American Dietetic Association was the most-cited journal. Researchers can maximize search efficiency by searching a small yet targeted selection of both scholarly and gray literature resources. A highly sensitive search of PubMed and those databases that index the greatest number of relevant articles not indexed in PubMed, namely multidisciplinary and economics databases, could save considerable time and effort. When combined with a gray literature search and additional search methods, including cited reference searching and consulting with experts, this approach could help maintain broad retrieval of relevant studies while improving search efficiency. Findings also have implications for designing specialized databases for public health research.

    This study sought to explore the informational themes and information sources cited by the media to cover stories of cultured meat in both the United States and the European Union. The results indicated that cultured meat news articles in both the United States and the European Union commonly discuss cultured meat in terms of benefits, history, process, time, livestock production problems, and skepticism. Additionally, the information sources commonly cited in the articles included cultured meat researchers, sources from academia, People for the Ethical Treatment of Animals (PETA), New Harvest, Winston Churchill, restaurant owners/chefs, and sources from the opposing countries (e.g. US use some EU sources and vice versa). The implications of this study will allow meat scientists to understand how the media is influencing consumers' perceptions about the topic, and also allow them to strategize how to shape future communication about cultured meat.

  12. Explaining levels of within-group wage inequality in U.S. labor markets.

    PubMed

    McCall, L

    2000-11-01

    Most research on earnings inequality has focused on the growing gap between workers of different races and at different education, age, and income levels, but a large portion of the increasing inequality has actually occurred within these groups. This article focuses on the extent and sources of "within-group" wage inequality in more than 500 labor markets in the United States in 1990. In addition to documenting that within-group wage inequality across regions varies more widely today than over the past several decades, the analysis reveals that two frequently cited explanations of rising wage inequality over time have little impact on within-group wage inequality when measured at the local labor market level: (1) industrial shifts and (2) increased technology and trade. By contrast, flexible and insecure employment conditions (e.g., unemployment, contingent work, and immigration) are associated strongly with high local levels of within-group wage inequality, especially among women.

    2014-08-01

    Increasing the frequency with which injecting drug users (IDUs) engage in self-initiated harm reduction strategies could improve their health, but few investigations have examined IDUs' perceived barriers to engaging in these behaviors. We interviewed 90 IDUs recruited from needle exchanges to assess: a) perceived obstacles to their use of two specific harm reduction strategies (i.e., test shots and pre-injection skin cleaning) designed to reduce two unhealthy outcomes (i.e., overdose and bacterial infections, respectively) and b) their use of other risk-reduction practices. The most frequently cited barrier for both test shots and skin cleaning was being in a rush to inject one's drugs. Other, less commonly cited barriers were strategy-specific (e.g., buying drugs from a known dealer as a reason not to do a test shot; not having access to cleaning supplies as a reason not to clean skin). Regarding other risk reduction practices, participants' most frequently reported using new or clean injecting supplies and avoiding sharing needles and injecting supplies. Some, but not all, of the barriers generated by participants in our study were similar to those frequently reported in other investigations, perhaps due to differences in the type of sample recruited or in the harm reduction behaviors investigated.

    2008-01-01

    Purpose: The research assesses the impact of online journals on citation patterns by examining whether researchers were more likely to limit the resources they cited to those journals available online rather than those only in print. Setting: Publications from a large urban university with a medical college at an urban location and at a smaller regional location were examined. The number of online journals available to authors on either campus was the same. The number of print journals available on the large campus was much greater than the print journals available at the small campus. Methodology: Searches by author affiliation from 1996 to 2005 were performed in the Web of Science to find all articles written by affiliated members in the college of medicine at the selected institution. Cited references from randomly selected articles were recorded, and the cited journals were coded into five categories based on their availability at the study institution: print only, print and online, online only, not owned, and dropped. Results were analyzed using SPSS. The age of articles cited for selected years as well as for 2006 and 2007 was also examined. Results: The number of journals cited each year continued to increase. On the large urban campus, researchers were not more likely to cite journals available online or less likely to cite journals only in print. At the regional location, at which the number of print-only journals was minimal, use of print-only journals significantly decreased. Conclusion/discussion: The citation of print-only journals by researchers with access to a library with a large print and electronic collection appeared to continue, despite the availability of potential alternatives in the online collection. Journals available in electronic format were cited more frequently in publications from the campus whose library had a small print collection, and the citation of journals available in both print and electronic formats generally increased over the years studied.

    The aim of this study was to evaluate the evolution of the citation of articles from the European Journal of Emergency Medicine (EJEM) from 1994 (EJEM foundation) to 2015 and identify highly cited articles and their principal characteristics and determine a possible correlation between the citations counted in different databases. We obtained the articles published in EJEM from 1994 to 2015 in ISI-WoS (main source) and Scopus, Google Scholar, and Medline databases (accessory sources). The citations were quantified and their annual evolution and the bibliometric indices derived (impact factor and SCImago Journal Rank) were evaluated. We identified and analyzed the highly cited EJEM articles and evaluated the possible correlation between the citations counted for these articles in the databases. Overall, 1705 EJEM articles were cited 9422 times in 8122 different articles. The evolution of the global citation, impact factor, and SCImago Journal Rank from 1994 to 2015 increased significantly. The h-index of EJEM was 30, and 31 articles were considered highly cited (≥30 citations), 16.1% of them being clinical trials. By subjects, 22.5% corresponded to cardiology, 19.3% to emergency department management, and 12.9% to pediatrics; by countries, 81% were from Europe, with Belgian authors publishing four (12.9%) highly cited articles, and French, Spanish, British, and Swedish authors having three (9.7%) each. Two studies in the EJEM achieved the definition of 'citation classics' (more than 100 citations). The number of citations in all the databases, except Medline, showed statistically significant correlations. Citation of EJEM articles has progressively increased and EJEM bibliometric indicators have improved; most highly cited articles are mainly by European authors.

    2018-02-13

    Pelvic floor physiotherapy has been utilized extensively over the past decades for the treatment of pelvic floor dysfunctions. The aim of this study was to identify and characterize the most frequently cited articles on pelvic floor physiotherapy published in the last 30 years. A PubMed search of all articles published between 1983 and 2013 was performed. Articles with more than 100 citations were identified as "classic," and were further analyzed based on author names, year of publication, journal of publication, subject, study design, country of research, and number of citations. In 2017, a new search for papers on pelvic floor physiotherapy was conducted using the same methods to compare them with the 2013 data. Of 1,285 articles published between 1983 and 2013, only 20 articles were cited more than 100 times. Among them, we found 12 randomized clinical trials (RCTs) and only 4 reviews. The most common topics among the classic articles were behavior therapy, pelvic floor muscle training (PFMT), biofeedback-assisted PFMT, and neuromuscular electrical stimulation. In 2017, we found 1,745 papers containing the term "pelvic floor physiotherapy," indicating an increase of around 35% in 4 years. Although there is a fast-growing number of publications, we still have few classic papers on pelvic floor physiotherapy, concentrated in a few research centers. However, the large number of RCTs shows that these papers have a high scientific level, confirming that they can be classified as classic papers.

    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.

    Some characteristics of the skin are badly perceived by women living in a society where youth and idealized physical aspect are respected as a cult. Among the most frequent concerns, one should cite dry skin, wrinkles, striae distensae, cellulite, diffuse hair loss, hyperpilosity, as well as the unwanted effects of menopause and of the immoderate exposure to sun and sunbeds. Most of these concerns are subject to semantic confusions sustained by some medias. They are frequently targets of a worldwide ballyhoo conveyed to the general public without the support of sound physiopathological basis.

    Plagiarism among students is most common because of a misunderstanding of copyright and fair use. Images and text are frequently used without proper credit to the original author, and works are frequently acknowledged improperly. For example, space imagery is often used in posters, presentations, on the web, on Facebook, and even in the classrooms, but often are not properly cited. A lesson plan on fair use is presented, outlining what constitutes fair use and how to properly acknowledge the work done by artists and authors everywhere, with examples drawn from the Astronomy Picture of the Day (APOD).

    2014-01-01

    This study aimed to identify and analyze characteristics of highly cited articles published in the Web of Science category of health care sciences and services from 1958 to 2012. Articles that have been cited at least 100 times were assessed regarding publication outputs, distribution of outputs in journals, publications of authors, institutions, countries as well as citation life cycles of the articles with the highest total citations since its publication up to 2012 and the highest citations in 2012. Six bibliometric indicators were used to evaluate source countries, institutions, and authors. Total citations from the time the articles were first published to the end of 2012 and citations in 2012 only were applied. Additionally, Y-index was applied to evaluate publication characteristics of authors. A high percentage of authors had the same numbers of first author and corresponding author status of highly cited articles in health care sciences and services field. RESULTS showed that 890 of the most highly referenced articles, published between 1977 and 2009, had been cited at least 100 times. Medical Care and Journal of General Internal Medicine published the most highly cited articles. The United States produced 76% of highly cited articles and also published the most number of independent, internationally collaborative, first authored, corresponding authored, and single author highly cited articles. The Harvard University was the most productive institute and was number one for the total highly cited articles, inter-institutionally collaborative articles, single institution articles, first author articles, and corresponding author articles. The application of quantitative techniques in the analysis of highly cited articles can improve the researchers' understanding of the directions in health care sciences and services field. Y-index is useful for the evaluation of contributing authors.

    Though some researchers have indicated club drug users are more likely to be polydrug users, there remains little known about the prevalence and specific combinations of the substances they use. Between 2004-2006, and using time-space sampling, a stratified sample of 400 18-29 year old New York City club-going drug-using young adults were recruited into the Club Drugs and Health Project. Most participants (91.7%) had engaged in polydrug use and 1,670 combinations of drugs were reported. Ecstasy (86.6% of users) and cocaine (85.7% of users) were the two most frequently reported club drugs used in combination with other substances. In terms of poly-club-drug combinations, ecstasy appeared to be the “universal compliment” as this drug was most often cited in combinations with other club drugs (specifically ecstasy + ketamine, ecstasy + cocaine, ecstasy + GHB). Other frequently cited drug combinations included cocaine and marijuana, ecstasy and marijuana, LSD and marijuana, and cocaine and alcohol. These data highlight the need to develop drug health education and prevention messages targeted at polydrug use. PMID:19444726

  9. Wikipedia as an evidence source for nursing and healthcare students.

    Where students once were confined to the University library, they are now at liberty to wander through cyber-space at will. There is evidence to suggest that student have been very quick to exploit the opportunities that the Internet can offer them. Students frequently cited search engines such as Google and Web 2.0 information sharing sites such as Wikipedia as the first places they look when seeking information for an assignment. Although a number of disciplines have accepted that Wikipedia can be viewed as an accurate and legitimate evidence source nurse educators tend to view Wikipedia with a degree of suspicion. The purpose of this paper is to carry out an exploratory study of health and health related content on a sample of Wikipedia site with the overall intention of assessing the quality of their source and supporting information. A 10% sample of health related Wikipedia entries were evaluated, with a total of 2598 references assessed. In total 1473 (56%) of the references citied on the Wikipedia pages reviewed could be argued to come from clearly identifiable reputable sources. This translates to a mean number of reputable sources of M=29 per Wikipedia entry. The quality of the evidence taken obtained from the 2500 plus references from over 50 Wikipedia pages was of sufficiently sound quality to suggest that, for health related entries, Wikipedia is appropriate for use by nursing students.

  10. Sleeping beauties cited in patents: Is there also a dormitory of inventions?

    PubMed

    van Raan, Anthony F J

    2017-01-01

    A 'Sleeping Beauty in Science' is a publication that goes unnoticed ('sleeps') for a long time and then, almost suddenly, attracts a lot of attention ('is awakened by a prince'). In our foregoing study we found that roughly half of the Sleeping Beauties are application-oriented and thus are potential Sleeping Innovations. In this paper we investigate a new topic: Sleeping Beauties that are cited in patents. In this way we explore the existence of a dormitory of inventions. To our knowledge this is the first study of this kind. We investigate the time lag between publication of the Sleeping Beauty and the first citation by a patent. We find that patent citation may occur before or after the awakening and that the depth of the sleep, i.e., citation rate during the sleeping period, is no predictor for later scientific or technological impact of the Sleeping Beauty. A surprising finding is that Sleeping Beauties are significantly more cited in patents than 'normal' papers. Inventor-author self-citations relations occur only in a small minority of the Sleeping Beauties that are cited in patents, but other types of inventor-author links occur more frequently. We develop an approach in different steps to explore the cognitive environment of Sleeping Beauties cited in patents. First, we analyze whether they deal with new topics by measuring the time-dependent evolution in the entire scientific literature of the number of papers related to both the precisely defined topics as well as the broader research theme of the Sleeping Beauty during and after the sleeping time. Second, we focus on the awakening by analyzing the first group of papers that cites the Sleeping Beauty. Third, we create concept maps of the topic-related and the citing papers for a time period immediately following the awakening and for the most recent period. Finally, we make an extensive assessment of the cited and citing relations of the Sleeping Beauty. We find that tunable co-citation analysis is a powerful tool to discover the prince(s) and other important application-oriented work directly related to the Sleeping Beauty, for instance papers written by authors who cite Sleeping Beauties in both the patents of which they are the inventors, as well as in their scientific papers.

    The CRISPR/Cas system could provide an efficient and reliable means of editing the human genome and has the potential to revolutionise modern medicine; however, rapid developments are raising complex ethical issues. There has been significant scientific debate regarding the acceptability of some applications of CRISPR/Cas, with leaders in the field highlighting the need for the lay public's views to shape expert discussion. As such, we sought to determine the factors that influence public opinion on gene editing. We created a 17-item online survey translated into 11 languages and advertised worldwide. Topic modelling was used to analyse textual responses to determine what factors influenced respondents' opinions towards human somatic or embryonic gene editing, and how this varied between respondents with differing attitudes and demographic backgrounds. A total of 3,988 free text responses were analysed. Respondents had a mean age of 32 (11-90) and 37% were female. The most prevalent topics cited were 'Future Generations', 'Research', 'Human Editing', 'Children', and 'Health'. Respondents who disagreed with gene editing for health-related purposes were more likely to cite the topic 'Better Understanding' than those who agreed to both somatic and embryonic gene editing. Respondents from 'Western' backgrounds more frequently discussed 'Future Generations', compared to participants from 'Eastern' countries. Religious respondents did not cite the topic 'Religious Beliefs' more frequently than non-religious respondents, while Christian respondents were more likely to cite the topic 'Future Generations'. Our results suggest that public resistance to human somatic or embryonic gene editing does not stem from an inherent mistrust of genome modification, but rather a desire for greater understanding. Furthermore, we demonstrate that factors influencing public opinion vary greatly amongst demographic groups. It is crucial that the determinants of public attitudes towards CRISPR/Cas are well understood so that the technology does not suffer the negative public sentiment seen with previous genetic biotechnologies.

  12. Worldwide nanotechnology development: a comparative study of USPTO, EPO, and JPO patents (1976-2004)

    2007-12-01

    To assess worldwide development of nanotechnology, this paper compares the numbers and contents of nanotechnology patents in the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), and Japan Patent Office (JPO). It uses the patent databases as indicators of nanotechnology trends via bibliographic analysis, content map analysis, and citation network analysis on nanotechnology patents per country, institution, and technology field. The numbers of nanotechnology patents published in USPTO and EPO have continued to increase quasi-exponentially since 1980, while those published in JPO stabilized after 1993. Institutions and individuals located in the same region as a repository's patent office have a higher contribution to the nanotechnology patent publication in that repository ("home advantage" effect). The USPTO and EPO databases had similar high-productivity contributing countries and technology fields with large number of patents, but quite different high-impact countries and technology fields after the average number of received cites. Bibliographic analysis on USPTO and EPO patents shows that researchers in the United States and Japan published larger numbers of patents than other countries, and that their patents were more frequently cited by other patents. Nanotechnology patents covered physics research topics in all three repositories. In addition, USPTO showed the broadest representation in coverage in biomedical and electronics areas. The analysis of citations by technology field indicates that USPTO had a clear pattern of knowledge diffusion from highly cited fields to less cited fields, while EPO showed knowledge exchange mainly occurred among highly cited fields.

    exclusive breast feeding in China is relatively low and no research has been conducted to explore the difficulties and desires of Chinese lactating mothers. Currently, Chinese women turn to massage therapists to increase breastmilk volume, implying that many breast-feeding women faced problems but had few support mechanisms.This study aimed to explore the difficulties and desires of Chinese breast-feeding women and to propose strategies for increasing the rate of exclusive breast feeding. three hundred and seventy-five primiparous women were recruited from two randomized cluster communities in Wuhan following ethical approval. Face-to-face semistructured interviews were conducted with 76 of the participants to collect data on their infants' feeding status, duration of exclusive breast feeding, reasons for stopping, difficulties encountered, and sources of support for lactation. the breast feeding initiation rate was 93.6%, but exclusive breast feeding was only 6.2% at six months. The most frequently cited reason for giving up exclusive breast feeding was perceived breastmilk insufficiency. Women cited a desire for professional and individualised instruction from following resources: (1) lactation consultants in hospital and communities; (2) Qualified cuirushi; (3) breast feeding website;(4) Relatives, friends and peers;(5) Telephone hotline. to improve the rate and duration of exclusive breast feeding in China, effective and available resources must be available. Timely,professional and face-to-face lactation counselling such as lactation consultant, qualified cuirushin is needed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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. Cross-sectional, descriptive study. 14 states and the District of Columbia. Those receiving cell phone use while driving citations within included states from 2007 to 2013. 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. 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. 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.

    To determine the prevalence and type of dietary supplement used, reasons for use, and sources of supplement information among Macedonian elite Soldiers. Anonymous self-reported questionnaires containing questions about demographic characteristics and dietary supplementation practices were distributed to 134 Soldiers, of whom 80 were recruited from the Ranger Battalion (R) and 54 from the Special Force Battalion (SF). The Soldiers completed and returned 132 questionnaires. Overall, 66.6% of the Soldiers, including 70.3% of SF and 64.1% of R, reported using supplements within the 3 months before the survey. On average, each of these Soldiers used 3.7 ? 2.9 supplements. The most commonly used supplements were multivitamins (50.0%) and vitamin C (47.7%). The most frequently cited reason for using supplements was to improve general health (51.6%). Primary sources of supplement information were friends (42.0%) and books/magazines (40.9%). Dietary supplement use was found to be common and widespread among this military subpopulation. Given this, and the fact that the majority of the Soldiers do not receive accurate information about supplements, educational intervention regarding the safety and efficacy of these products is needed if unnecessary or harmful supplementation practices are to be prevented. 2013.

  19. Not so global: a bibliometric look at engineering education research

    2018-03-01

    It has been suggested that Engineering Education Research (EER) is going global. If this were the case we would assume that the research of EER scholars in different parts of the globe would be informed by literature describing prior work within and beyond their home country/region. The authors set out to test this hypothesis by applying citation analysis to research presented in four publication venues: the annual conferences organised by ASEE (American Society of Engineering Education) and SEFI (European Society of Engineering Education) and two archival journals published by these two societies: Journal of Engineering Education (JEE) and European Journal of Engineering Education (EJEE). Our findings from the analysis of 4321 publications show that citations in ASEE conferences are dominated by sources with US affiliations, whereas the SEFI data show that while US sources are frequently cited, European and other authors are also well represented. With regard to the journals JEE and EJEE, a similar pattern is observed. These results suggest that, in citation terms, European EER is relatively global but US EER is not. The authors conclude by suggesting that if the EER community is to aspire to quality scholarship, there needs to be debate around how such issues can be tackled.

    2003-08-01

    The American Society of Anesthesiologists (ASA) Physical Status (PS) Classification is used worldwide by anesthesia providers as an assessment of the preoperative physical health of patients. This score also has been used in policy-making, performance evaluation, resource allocation, and reimbursement of anesthesia services and frequently is cited in clinical research. The purpose of this study was to assess interrater reliability and describe sources of variability among anesthesia providers in assigning ASA PS scores. A questionnaire with 10 hypothetical patients scenarios was given to 70 anesthesia providers who were asked to assign ASA PS scores in each scenario and to provide rationale for their decisions. The data were summarized and stratified according to nurse anesthetist or anesthesiologist and military or nonmilitary anesthesia providers. We hypothesized there would be no difference between any of the anesthesia provider groups in assignment of ASA PS scores. A lack of interrater reliability in assigning ASA PS scores was demonstrated. There were no significant differences between the anesthesia provider groups. There was no correlation between ASA PS scoring and years practicing or any of the other demographic variables. Several sources of variability were identified: smoking, pregnancy, nature of the surgery, potential difficult airway, and acute injury.

    2007-08-01

    Academic nanoscale science and engineering (NSE) research provides a foundation for nanotechnology innovation reflected in patents. About 60% or about 50,000 of the NSE-related patents identified by "full-text" keyword searching between 1976 and 2004 at the United States Patent and Trademark Office (USPTO) have an average of approximately 18 academic citations. The most cited academic journals, individual researchers, and research articles have been evaluated as sources of technology innovation in the NSE area over the 28-year period. Each of the most influential articles was cited about 90 times on the average, while the most influential author was cited more than 700 times by the NSE-related patents. Thirteen mainstream journals accounted for about 20% of all citations. Science, Nature and Proceedings of the National Academy of Sciences (PNAS) have consistently been the top three most cited journals, with each article being cited three times on average. There is another kind of influential journals, represented by Biosystems and Origin of Life, which have very few articles cited but with exceptionally high frequencies. The number of academic citations per year from ten most cited journals has increased by over 17 times in the interval (1990-1999) as compared to (1976-1989), and again over 3 times in the interval (2000-2004) as compared to (1990-1999). This is an indication of increased used of academic knowledge creation in the NSE-related patents.

    2010-09-01

    We conducted a citation analysis to explore the impact of articles published in Health Psychology and determine whether the journal is fulfilling its stated mission. Six years of articles (N = 408) representing three editorial tenures from 1993-2003 were selected for analysis. Articles were coded for several dimensions enabling examination of the relationship of article features to subsequent citations rates. Journals citing articles published in Health Psychology were classified into four categories: (1) psychology, (2) medicine, (3) public health and health policy, and (4) other journals. The majority of citations of Health Psychology articles were in psychology journals, followed closely by medical journals. Studies reporting data collected from college students, and discussing the theoretical implications of findings, were more likely to be cited in psychology journals, whereas studies reporting data from clinical populations, and discussing the practice implications of findings, were more likely to be cited in medical journals. Time since publication and page length were both associated with increased citation counts, and review articles were cited more frequently than observational studies. Articles published in Health Psychology have a wide reach, informing psychology, medicine, public health and health policy. Certain characteristics of articles affect their subsequent pattern of citation. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

    The number of citations that a published article has received reflects the importance of the paper in the particular area of practice. In microsurgery, thus far, which journal articles are cited most frequently is unknown. The purpose of this study was to identify and analyze the characteristics of the top 50 papers in the field of microsurgery in the plastic surgery literature. The 50 most cited papers published in high impact plastic surgery and microsurgery journals were identified. The articles were ranked in the order of the number of citations received. These 50 classic papers were analyzed for article type, journal distribution, and geographic and institutional origin. Six international journals contributed to the top 50 papers in microsurgery. The most cited paper reported on the early use of the vascularized bone graft and was cited 116 times. The top 50 papers originated from just 10 countries with the United States producing the most. The Preston and Northcote Community Hospital, Melbourne published 5 papers and this was the most productive institution in the top 50. These papers represent many important milestones in the relatively short history of microsurgery. Furthermore, our citation analysis provides useful information to budding authors as to what makes a paper attain a "classic" status.

    In the 1970s Thomas McKeown and Archibald L Cochrane were two of the most influential voices in criticizing the dominance of medical thinking. A bibliometric study of the citations to McKeown's The Role of Medicine: Dream, Mirage or Nemesis and Cochrane's Effectiveness and Efficiency: Random Reflections on Health Services was performed from the publication of each book until 1988 to study how their ideas have been disseminated. During the study period 430 papers in the Science Citation Index or the Social Sciences Citation Index cited Cochrane's book, 133 cited McKeown's, and 166 cited both. The citations came mainly from original papers published in journals of internal medicine or public health and epidemiology (35%) and written by authors from the United States or the United Kingdom. Cochrane's book was cited most frequently in medical journals, suggesting a higher degree of penetration of his ideas among medical scientists. Although the dominance of original papers among the citations suggests that these books have been important in stimulating new knowledge, the main problems that McKeown and Cochrane identified--namely, the relatively small impact of clinical medicine on health outcomes and the poor use of scientific methods in clinical practice--are still with us.

    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.

    This study identified the most frequently cited scholars across 28 leading multicultural textbooks used in the training of counselors and counseling psychologists. Four spheres or clusters of multicultural scholars were identified and were characterized, respectively, as having either a profound, highly significant, significant, or important impact on the academic multicultural training of counseling graduate students. The top-cited scholars across the textbooks were also examined in relation to their scholarly productivity (number of publications) and their impact (number of citations) in peer-reviewed journals. Specifically, multicultural scholars were assessed on the delta-beta coefficient, Scopus and PsycINFO publications count, Scopus citations, and the increasingly popular h-index of scientific impact. Limitations of the study and implications of the findings for counseling training were highlighted.

    2007-01-01

    This study, part of a wider project to map the literature of nursing, identifies core journals cited in non-US nursing journals and determines the extent of their coverage by indexing services. Four general English-language journals were analyzed for format types and publication dates. Core titles were identified and nine bibliographic databases were scanned for indexing coverage. Findings show that 57.5% (13,391/23,271) of the cited references from the 4 core journals were to journal articles, 27.8% (6,471/23,271) to books, 9.5% (2,208/23,271) to government documents, 4.9% (1,131/23,271) to miscellaneous sources, and less than 1% (70/23,271) to Internet resources. Eleven journals produced one-third of the citations; the next third included 146 journals, followed by a dispersion of 1,622 titles. PubMed received the best database coverage scores, followed by CINAHL and Science Citation Index. None of the databases provided complete coverage of all 11 core titles. The four source journals contain a diverse group of cited references. The currency of citations to government documents makes these journals a good source for regulatory and legislative awareness. Nurses consult nursing and biomedical journals and must search both nursing and biomedical databases to cover the literature.

    Intimate partner violence (IPV) in late life takes various forms including physical harm, sexual assault, and murder. Using national newspaper reports of IPV among elders, we identified the types of violence reported most frequently in media and examined how the abuse was conceptualized by reporters. We found that most cases of IPV reported involved murder, with men as perpetrators and women as victims. Caregiving stress and health problems were frequently cited as contributing factors in the cases. Interpreting these findings from a feminist perspective, we suggest implications for practitioners working with older adults. PMID:23627429

    2013-07-01

    This study examined citation patterns and indexing coverage from 2008 to 2010 to determine (1) the core literature of health care chaplaincy and (2) the resources providing optimum coverage for the literature. Citations from three source journals (2008-2010 inclusive) were collected and analyzed according to the protocol created for the Mapping the Literature of Allied Health Professions Project. An analysis of indexing coverage by five databases was conducted. A secondary analysis of self-citations by source journals was also conducted. The 3 source journals--Chaplaincy Today, the Journal of Health Care Chaplaincy, and the Journal of Pastoral Care and Counseling--ranked as the top 3 journals in Zone 1 and provided the highest number of most frequently cited articles for health care chaplaincy. Additional journals that appeared in this highly productive zone covered the disciplines of medicine, psychology, nursing, and religion, which were also represented in the Zones 2 and 3 journals. None of the databases provided complete coverage for the core journals; however, MEDLINE provided the most comprehensive coverage for journals in Zones 1 and 2, followed by Academic Search Complete, CINAHL, PsycINFO, and ATLA. Self-citations for the source journals ranged from 9% to 16%. Health care chaplaincy draws from a diverse body of inter-professional literature. Libraries wishing to provide access to journal literature to support health care chaplaincy at their institutions will be best able to do this by subscribing to databases and journals that cover medical, psychological, nursing, and religion- or spirituality-focused disciplines.

  12. Mapping the literature of nursing administration.

    PubMed

    Galganski, Carol J

    2006-04-01

    As part of Phase I 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 the core literature cited in nursing administration and the indexing services that provide access to the core journals. The results of this study will assist librarians and end users searching for information related to this nursing discipline, as well as database producers who might consider adding specific titles to their indexing services. Using the common methodology described in the overview article, five source journals for nursing administration were identified and selected for citation analysis over a three-year period, 1996 to 1998, to identify the most frequently cited titles according to Bradford's Law of Scattering. From this core of most productive journal titles, the bibliographic databases that provide the best access to these titles were identified. Results reveal that nursing administration literature relies most heavily on journal articles and on those titles identified as core nursing administrative titles. When the indexing coverage of nine services is compared, PubMed/MEDLINE and CINAHL provide the most comprehensive coverage of this nursing discipline. No one indexing service adequately covers this nursing discipline. Researchers needing comprehensive coverage in this area must search more than one database to effectively research their projects. While PubMed/MEDLINE and CINAHL provide more coverage for this discipline than the other indexing services, none is sufficiently broad in scope to provide indexing of nursing, health care management, and medical literature in a single file. Nurse administrators using the literature to research current work issues need to review not only the nursing titles covered by CINAHL but should also include the major weekly medical titles, core titles in health care administration, and general business sources if they wish to adequately cover the many aspects of nursing administration.

  13. When ab ≠ c - c': published errors in the reports of single-mediator models.

    PubMed

    Petrocelli, John V; Clarkson, Joshua J; Whitmire, Melanie B; Moon, Paul E

    2013-06-01

    Accurate reports of mediation analyses are critical to the assessment of inferences related to causality, since these inferences are consequential for both the evaluation of previous research (e.g., meta-analyses) and the progression of future research. However, upon reexamination, approximately 15% of published articles in psychology contain at least one incorrect statistical conclusion (Bakker & Wicherts, Behavior research methods, 43, 666-678 2011), disparities that beget the question of inaccuracy in mediation reports. To quantify this question of inaccuracy, articles reporting standard use of single-mediator models in three high-impact journals in personality and social psychology during 2011 were examined. More than 24% of the 156 models coded failed an equivalence test (i.e., ab = c - c'), suggesting that one or more regression coefficients in mediation analyses are frequently misreported. The authors cite common sources of errors, provide recommendations for enhanced accuracy in reports of single-mediator models, and discuss implications for alternative methods.

    Despite the recognised importance of accurate mental illness information in help-seeking and improving recovery, little is known about the dissemination of such information to people with depression. With a view to informing effective communication to those most in need, we explored the extent to which mental illness information is received by people with depression, its perceived helpfulness and we characterise those who do not receive such information. Using data from the Australian National Survey of Mental Health and Wellbeing we observed that mental illness information was received by 54.7 % of those with depression. Most (76.7 %) found it helpful. Pamphlets were the most frequently cited source of information. People who did not receive information were less educated, unlikely to have accessed mental health services and unlikely to believe they had mental health needs. Targeted information campaigns which shape perceptions of need in relation to depression have the potential to reduce the resultant disease burden.

    Descriptive and analytical data regarding the flow of aerospace-based scientific and technical information (STI) in the academic community are presented. An overview is provided of the Federal Aerospace Knowledge Diffusion Research Project, illustrating a five-year program on aerospace knowledge diffusion. Preliminary results are presented of the project's research concerning the information-seeking habits, practices, and attitudes of U.S. aerospace engineering and science students and faculty. The type and amount of education and training in the use of information sources are examined. The use and importance ascribed to various information products by U.S. aerospace faculty and students including computer and other information technology is assessed. An evaluation of NASA technical reports is presented and it is concluded that NASA technical reports are rated high in terms of quality and comprehensiveness, citing Engineering Index and IAA as the most frequently used materials by faculty and students.

  16. English children as personality theorists: accounts of the modifiability, development, and origin of traits.

    PubMed

    Yuill, N

    1997-02-01

    Forty-eight children, 4, 6, 7, and 10 years old, were interviewed to assess their accounts of the modifiability, development, and origin of four character traits (grumpy, shy, mean, fussy) and two physical traits (fat, thin). The youngest children described traits as moderately controllable and usually stable, whereas for the 2 middle groups, physiological traits in particular were highly modifiable and less stable. Six-year-olds frequently cited preferences as sources of individual differences, possibly as a precursor to a fuller understanding of traits as internal, partly uncontrollable, and idiosyncratic attributes. Seven-year-olds were more likely to mention cognitively mediated accounts of personality change, as were 10-year-olds, who were also more aware of the interactive and variable nature of influences on personality. All age groups showed coherent patterns of trait explanation and used different models of explanation for different traits. The results suggest that a monolithic model of trait understanding is misleading, because the children used a variety of different models of development.

    YouTube is an important resource for patients. No study has evaluated the information on peripheral neuropathy disseminated by YouTube videos. In this study, our aim was to perform a systematic review of information on YouTube regarding peripheral neuropathy. The Web site (www.youtube.com) was searched between September 19 and 21, 2014, for the terms "neuropathy," "peripheral neuropathy," "diabetic neuropathy," "neuropathy causes," and "neuropathy treatment." Two hundred videos met the inclusion criteria. Healthcare professionals accounted for almost half of the treatment videos (41 of 92; 44.6%), and most came from chiropractors (18 of 41; 43.9%). Alternative medicine was cited most frequently among the treatment discussions (54 of 145, 37.2%), followed by devices (38 of 145, 26.2%), and pharmacological treatments (23 of 145, 15.9%). Approximately half of the treatment options discussed in the videos were not evidence-based. Caution should be exercised when YouTube videos are used as a patient resource. © 2015 Wiley Periodicals, Inc.

    This glossary provides standard definitions for many of the terms used in avian conservation biology. We compiled these definitions to assist communication among researchers, managers, and others involved in the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight. We used existing glossaries and recent literature to prepare this glossary. The cited sources were not necessarily the first ones to use the terms. Many definitions were taken verbatim from the cited source material. Others were modified slightly to clarify the meaning. Definitions that were modified to a greater extent are indicated as being adapted from the originals. Terms that have been used in more than one way by different authors are listed with numbered alternative definitions if the definitions differ substantially.

  19. Forty years of secondhand smoke research: the gap between discovery and delivery.

    Harris, Jenine K; Luke, Douglas A; Zuckerman, Rachael B; Shelton, Sarah C

    2009-06-01

    Public health initiatives often focus on the discovery of risk factors associated with disease and death. Although this is an important step in protecting public health, recently the field has recognized that it is critical to move along the continuum from discovery of risk factors to delivery of interventions, and to improve the quality and speed of translating scientific discoveries into practice. To understand how public health problems move from discovery to delivery, citation network analysis was used to examine 1877 articles on secondhand smoke (SHS) published between 1965 and 2005. Data were collected and analyzed in 2006-2007. Citation patterns showed discovery and delivery to be distinct areas of SHS research. There was little cross-citation between discovery and delivery research, including only nine citation connections between the main paths. A discovery article was 83.5% less likely to cite a delivery article than to cite another discovery article (OR=0.165 [95% CI=0.139, 0.197]), and a delivery article was 64.3% less likely (OR=0.357 [95% CI=0.330, 0.386]) to cite a discovery article than to cite another delivery article. Research summaries, such as Surgeon General reports, were cited frequently and appear to bridge the discovery-delivery gap. There was a lack of cross-citation between discovery and delivery, even though they share the goal of understanding and reducing the impact of SHS. Reliance on research summaries, although they provide an important bridge between discovery and delivery, may slow the development of a field.

  20. 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.

    2015-09-01

    Microsurgery has developed significantly since the inception of the first surgical microscope. There have been few attempts to describe "classic" microsurgery articles. In this study citation analysis was done to identify the most highly cited clinical and basic science articles published in five peer-reviewed plastic surgery journals. Thomson/Reuters web of knowledge was used to identify the most highly cited microsurgery articles from five journals: Plastic and Reconstructive Surgery, Annals of Plastic Surgery, Journal of Plastic, Reconstructive & Aesthetic Surgery, Journal of Reconstructive Microsurgery, and Microsurgery. Articles were identified and sorted based on the number of citations and citations per year. The 50 most cited clinical and basic science articles were identified. For clinical articles, number of total citations ranged from 120 to 691 (mean, 212.38) and citations per year ranged from 30.92 to 3.05 (mean, 9.33). The most common defect site was the head and neck (n = 15, 30%), and flaps were perforator and muscle/musculocutaneous flaps (n = 10 each, 20%, respectively). For basic science articles, number of citations ranged from 71 to 332 (mean, 130.82) and citations per year ranged from 2.20 to 11.07 (mean, 5.27). There were 27 animal, 21 cadaveric, and 2 combined studies. The most highly cited microsurgery articles are a direct reflection of the educational and clinical trends. Awareness of the most frequently cited articles may serve as a basis for core knowledge in the education of plastic surgery trainees. III.

    The accuracy of references and quotations used to substantiate statements of fact in articles published in 6 frequently cited veterinary journals was examined. Three hundred references were randomly selected, and the accuracy of each citation was examined. A subset of 100 references was examined for quotational accuracy; ie, the accuracy with which authors represented the work or assertions of the author being cited. Of the 300 references selected, 295 were located, and 125 major errors were found in 88 (29.8%) of them. Sixty-seven (53.6%) major errors were found involving authors, 12 (9.6%) involved the article title, 14 (11.2%) involved the book or journal title, and 32 (25.6%) involved the volume number, date, or page numbers. Sixty-eight minor errors were detected. The accuracy of 111 quotations from 95 citations in 65 articles was examined. Nine quotations were technical and not classified, 86 (84.3%) were classified as correct, 2 (1.9%) contained minor misquotations, and 14 (13.7%) contained major misquotations. We concluded that misquotations and errors in citations occur frequently in veterinary journals, but at a rate similar to that reported for other biomedical journals.

    Pediatric medicine often struggles to receive adequate research funding for its small, yet vulnerable population of patients. Remarkable discovery in pediatric oncology is credited in large part to the collaborative structure of its research community. The Children's Oncology Group conducts studies supported by the National Cancer Institute. The clinical research associate (CRA) discipline comprises professionals who support administrative duties, regulatory duties, subject management, and data collection at individual research sites. The purpose of this study was to identify factors associated with CRA retention, as the group continues to have high turnover and position vacancy. A cross-sectional survey design was used to characterize the most frequently cited reasons CRAs gave when considering leaving or staying within their position. Results suggest that low salary, unmanageable workload, lack of career advancement and professional development, and lack of research commitment from the medical team were associated with intent to leave CRA positions. The most frequently cited reasons for staying at their job were the meaningfulness and interest in the work, a supportive principal investigator, and enjoyment working with colleagues. CRAs reported serious but eminently solvable issues that can be addressed using practical and low-cost solutions to improve job satisfaction and retention.

    The majority of disaster survivors suffering from psychological symptoms do not receive mental health services. Research on barriers to service use among disaster survivors is limited by a lack of longitudinal studies of representative samples and investigations of predictors of barriers. The purpose of this study was to address these limitations through analysis of a three-wave population-based study of Hurricane Ike survivors (N = 658). Frequencies of preference, outcome expectancy, resource, and stigma barriers among participants with unmet mental health needs were documented and logistic regression using a generalized estimating equations approach explored predisposing (e.g., age), illness-related (e.g., posttraumatic stress) and enabling (e.g., insurance coverage) factors as predictors of each type of barrier. Preference barriers were most frequently cited at each wave, whereas stigma barriers were least frequently cited. Older age and higher emotional support predicted preference barriers; being a parent of a child under 18-years old at the time of the hurricane, higher generalized anxiety, and lack of insurance predicted resource barriers; and higher posttraumatic stress predicted stigma barriers. These findings suggest that postdisaster practices targeting subpopulations most likely to have barriers to service use may be indicated.

    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. 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. 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. 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.

    Although young adult women consume the majority of their total daily energy intake from home food sources, the decision-making processes that shape their home food environments have received limited attention. Further, how decision-making may be affected by the transformative experience of motherhood is unknown. In this study, we explore the factors that influence two key decision-making processes-food choices while grocery shopping and the use of non-home food sources-and whether there are differences by motherhood status. In-depth interviews were conducted with 40 women, aged 20-29, living in southwest Georgia. Thematic analysis was used to analyze qualitative data stratified by whether or not children were present in the home. Decision-making was affected by numerous factors, which differed across groups. In regard to grocery shopping, women with children more frequently discussed the influence of nutrition and the preferences of children, while women without children more frequently discussed the influence of taste and the preferences of other household members. Cost, convenience, weight control, and pre-planning meals emerged as salient in both groups. In regard to the use of non-home food sources, convenience and taste were discussed by both groups, while social factors were only discussed by women without children. The cost of eating out was the only reason cited for eating inside the home, and this factor only emerged among women with children. Motherhood may be an important contributor to the decision-making processes that shape young adult women's home food environments. Interventions may find success in framing messaging to emphasize factors identified as motivating healthy decisions, such as protecting the health of children, and practical strategies may be adapted from those already in use, such as pre-planning and budgeting for healthy meals.

  2. Enacting the Carnegie Foundation call for reform of medical school and residency.

    On the 100th anniversary of the Flexner Report, the Carnegie Foundation for the Advancement of Teaching published a new study of medical education. This study, titled Educating Physicians: A Call for Reform of Medical Schools and Residency Programs, contained four primary recommendations intended to stimulate innovation and improvement in medical education. In this article, the authors examined the ways others have applied the four recommendations from Educating Physicians within and beyond medical education. In their review of 246 publications citing the Carnegie work, they found that the recommendation for integration was addressed most frequently, often through descriptions of integration of curricular content in undergraduate medical education. The recommendation to focus on professional identity formation was the second most frequently addressed, followed by standardization and individualization, then inquiry, innovation, and improvement. The publications related to these latter three recommendations tended to be conceptual rather than descriptive or empirical. Publications spanned the continuum of medical education (from medical school to residency to physicians in practice) and even into other fields, but undergraduate medical education received the most attention. The authors discuss common themes among the citing publications and highlight opportunities for further discussion and innovation. Many exciting developments have occurred in medical education and beyond since the publication of Educating Physicians in 2010. Thus far, most of the publications citing the Carnegie recommendations describe incremental changes in medical education, particularly in the area of integration. Some of the conceptual work around these recommendations, coupled with a variety of external factors such as changes in health care and accreditation systems, suggests the potential for changes that are more transformative in nature.

    Objectives Although cognitive behavioural therapy and graded exercise treatment are recognized evidence-based treatments for chronic fatigue syndrome/myalgic encephalomyelitis (ME), their use is still considered controversial by some patient groups. This debate has been reflected in the media, where many patients gather health information. The aim of this study was to examine how treatment for chronic fatigue syndrome/ME is described in the newspaper media. Design Content analysis of newspaper articles. Setting The digitalized media archive Atekst was used to identify Norwegian newspaper articles where chronic fatigue syndrome/ME was mentioned. Participants Norwegian newspaper articles published over a 20-month period, from 1 January 2008 to 31 August 2009. Main outcome measures Statements regarding efficiency of various types of treatment for chronic fatigue syndrome/ME and the related source of the treatment advice. Statements were categorized as being either positive or negative towards evidence-based or alternative treatment. Results One hundred and twenty-two statements regarding treatment of chronic fatigue syndrome/ME were identified among 123 newspaper articles. The most frequent statements were positive statements towards alternative treatment Lightning Process (26.2%), negative statements towards evidence-based treatments (22.1%), and positive statements towards other alternative treatment interventions (22.1%). Only 14.8% of the statements were positive towards evidence-based treatment. Case-subjects were the most frequently cited sources, accounting for 35.2% of the statements, followed by physicians and the Norwegian ME association. Conclusions Statements regarding treatment for chronic fatigue syndrome/ME in newspapers are mainly pro-alternative treatment and against evidence-based treatment. The media has great potential to influence individual choices. The unbalanced reporting of treatment options for chronic fatigue syndrome/ME in the media is potentially harmful. PMID:21637403

    We examined and contrasted 129 Canadian-born and immigrant women's experiences of violence and associated structural and interpersonal factors within indoor commercial sex venues. The majority experienced at least one form of structural, interpersonal, or both types of violence, with the attempted removal of a condom during sexual services being cited most frequently. Canadian-born women reported more frequent violent assaults in the survey data. The women's qualitative narratives illustrated that perceptions of violence differed significantly among Canadian versus non-Canadian born women. Findings concerning racialization and gendered relations of power have important implications for prevention and interventions to support victims of abuse.

    Military orthopaedic surgeons have published a substantial amount of original research based on our care of combat-wounded service members and related studies during the wars in Iraq and Afghanistan. However, to our knowledge, the influence of this body of work has not been evaluated bibliometrically, and doing so is important to determine the modern impact of combat casualty research in the wider medical community. We sought to identify the 20 most commonly cited works from military surgeons published during the Iraq and Afghanistan conflicts and analyze them to answer the following questions: (1) What were the subject areas of these 20 articles and what was the 2013 Impact Factor of each journal that published them? (2) How many citations did they receive and what were the characteristics of the journals that cited them? (3) Do the citation analysis results obtained from Google Scholar mirror the results obtained from Thompson-Reuters' Web of Science? We searched the Web of Science Citation Index Expanded for relevant original research performed by US military orthopaedic surgeons related to Operation Iraqi Freedom and Operation Enduring Freedom between 2001 and 2014. Articles citing these studies were reviewed using both Web of Science and Google Scholar data. The 20 most cited articles meeting inclusion criteria were identified and analyzed by content domain, frequency of citation, and sources in which they were cited. Nine of these studies examined the epidemiology and outcome of combat injury. Six studies dealt with wound management, wound dehiscence, and formation of heterotopic ossification. Five studies examined infectious complications of combat trauma. The median number of citations garnered by these 20 articles was 41 (range, 28-264) in Web of Science. Other research citing these studies has appeared in 279 different journals, covering 26 different medical and surgical subspecialties, from authors in 31 different countries. Google Scholar contained 97% of the Web of Science citations, but also had 31 duplicate entries and 29 citations with defective links. Modern combat casualty research by military orthopaedic surgeons is widely cited by researchers in a diverse range of subspecialties and geographic locales. This suggests that the military continues to be a source of innovation that is broadly applicable to civilian medical and surgical practice and should encourage expansion of military-civilian collaboration to maximize the utility of the knowledge gained in the treatment of war trauma. Level IV, therapeutic study.

    To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the quality of the research, but the present study gives some clues to the topics and authors contributing to major advances in Dentistry.

    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.

  15. Risk reporting in the Chinese news media in response to radiation threat from the Fukushima nuclear reactor crisis

    Wen Wang

    On March 11, 2011, the northeastern coast of Japan was struck by 9.0-magnitude earthquake that triggered a devastating tsunami. Aside from the huge toll in people's lives and severe damages to property, the tremor sent the Fukushima Daiichi Nuclear Power Plant on a tailspin, causing hydrogen explosions in three reactors, and sending radioactive materials into the air and bodies of water. Declared the largest nuclear disaster since Chernobyl, the crisis threatened neighboring countries, including China (International Business Times, 2011). On March 28, low levels of iodine-131, cesium-137 and strontium, believed to have drifted from Japan, were detected in the airmore » over Heilongjiang province in the northeast part of China and in seawater samples collected in the eastern coastal areas (Qianjiang Eve News, 2011). Because these chemicals can enter the food chain and adversely affect human health (Ifeng.com, 2011), people became understandably anxious and the government had to avert panic. This study asks: How did the Chinese media report the risks attendant to this event? A content analysis of 45 straight news reports published by the Chinese press from March 16, 2011 to April 25, 2011 was conducted. The analysis focused on how the media explained the risk, portrayed potential harm, reported on government actions to safeguard public health, and provided suggestions to reduce public fear. The sources of information cited in the reports were also identified. The articles examined were collected from People.com, a comprehensive online archive of news reports, using 'Fukushima' and 'nuclear radiation' as search terms. The results indicated journalistic practices that left much to be desired in terms of risk reporting. First, the articles explained little about the technical aspects of the radiation leaks and failed to give audiences a general indication of levels of risk. Second, the media over-emphasized the government's position that the environment was safe despite the more rampant word-of-mouth reports to the contrary, a slant that may have done nothing to allay public fear. Third, there was a dearth of information about what the government intends to do to alleviate the situation and suggestions about what people can do to protect themselves. The themes of news reports may be attributed to experts from research institutions and government officials who were the most frequently cited sources of facts, analyses, interpretations, and opinions. Scientists and nuclear experts were cited the most in the news reports. (authors)« less

  16. KNOWLEDGE, ATTITUDE AND PERCEPTION REGARDING ANTIBIOTICS AMONG POLISH PATIENTS.

    PubMed

    2015-01-01

    Antibiotics are drugs often used. This drugs used without legitimate indications or incorrectly may cause not satisfactory clinical results. It is therefore important for the society members to be aware of what is an antibiotic and which benefits and risks its use may bring. The survey was conducted in 2010. Objective of the study was to obtain information on the current knowledge and beliefs about antibiotic therapy of Poles. The research material consisted of 609 questionnaires and interviews, conducted among the adult population residing in the Lublin voivodeship. The study shows that rural inhabitants don't know the term herbal medicine or antibiotic more often than inhabitants in the city. Similarly, they more often don't know the action of antibiotics as well as use them less frequently. Poles treat them as an emergency exit if they are not helped by home treatments. There was a problem of overuse of antibiotics, related to young people, which were busy and have no time for illness. Self-medication in the antibiotic therapy also occurs and is caused, among others, by undisciplined patients. The respondents admited that they have antibiotics from the previous treatment, from pharmacy, or from family or friends. However, residents of rural areas using an antibiotic most frequently, cited a pharmacy as the source of this drug. Other issues dealt within this study generally doesn't differ for rural inhabitants from the data obtained among the urban population.

    The research blog has become a popular mechanism for the quick discussion of scholarly information. However, unlike peer-reviewed journals, the characteristics of this form of scientific discourse are not well understood, for example in terms of the spread of blogger levels of education, gender and institutional affiliations. In this paper we fill this gap by analyzing a sample of blog posts discussing science via an aggregator called ResearchBlogging.org (RB). ResearchBlogging.org aggregates posts based on peer-reviewed research and allows bloggers to cite their sources in a scholarly manner. We studied the bloggers, blog posts and referenced journals of bloggers who posted at least 20 items. We found that RB bloggers show a preference for papers from high-impact journals and blog mostly about research in the life and behavioral sciences. The most frequently referenced journal sources in the sample were: Science, Nature, PNAS and PLoS One. Most of the bloggers in our sample had active Twitter accounts connected with their blogs, and at least 90% of these accounts connect to at least one other RB-related Twitter account. The average RB blogger in our sample is male, either a graduate student or has been awarded a PhD and blogs under his own name. PMID:22606239

  20. Top-Cited Articles in Problem-Based Learning: A Bibliometric Analysis and Quality of Evidence Assessment.

    2017-04-01

    The aims of this study were to identify characteristics of the top-cited articles in problem-based learning (PBL) and assess the quality of evidence provided by these articles. The most frequently cited articles on PBL were searched in April 2015 in the Science Citation Index Expanded database (List A) and Google Scholar database (List B). 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.

    The study was designed to investigate the frequency of misusing standard error of the mean (SEM) in place of standard deviation (SD) to describe study samples in four selected journals published in 2011. Citation counts of articles and the relationship between the misuse rate and impact factor, immediacy index, or cited half-life were also evaluated. All original articles in the four selected journals published in 2011 were searched for descriptive statistics reporting with either mean ± SD or mean ± SEM. The impact factor, immediacy index, and cited half-life of the journals were gathered from Journal Citation Reports Science edition 2011. Scopus was used to search for citations of individual articles. The difference in citation counts between the SD group and SEM group was tested by the Mann-Whitney U test. The relationship between the misuse rate and impact factor, immediacy index, or cited half-life was also evaluated. The frequency of inappropriate reporting of SEM was 13.60% for all four journals. For individual journals, the misuse rate was from 2.9% in Acta Obstetricia et Gynecologica Scandinavica to 22.68% in American Journal of Obstetrics & Gynecology. Articles using SEM were cited more frequently than those using SD (p = 0.025). An approximate positive correlation between the misuse rate and cited half-life was observed. Inappropriate reporting of SEM is common in medical journals. Authors of biomedical papers should be responsible for maintaining an integrated statistical presentation because valuable articles are in danger of being wasted through the misuse of statistics.

    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.

    In the past 12 years, during the process of imaging congenital heart disease (CHD), Asian doctors have not only made every effort to adhere to established magnetic resonance imaging (MRI) protocols as in Western countries, but also have developed Computed tomography (CT) as an alternative problem-solving technique. Databases have shown that Asian doctors were more inclined to utilize CT than MRI in evaluating CHD. Articles in the literature focusing on CT have been cited more frequently than articles on MRI. Additionally, several repeatedly cited CT articles have become seminal papers in this field. The database reflects a trend suggesting that Asian doctors actively adapt to new techniques and flexibly develop unique strategies to overcome limitations caused by the relatively limited resources often available to them.

  4. Technical structure of the global nanoscience and nanotechnology literature

    2007-10-01

    Text mining was used to extract technical intelligence from the open source global nanotechnology and nanoscience research literature. An extensive nanotechnology/nanoscience-focused query was applied to the Science Citation Index/Social Science Citation Index (SCI/SSCI) databases. The nanotechnology/nanoscience research literature technical structure (taxonomy) was obtained using computational linguistics/document clustering and factor analysis. The infrastructure (prolific authors, key journals/institutions/countries, most cited authors/journals/documents) for each of the clusters generated by the document clustering algorithm was obtained using bibliometrics. Another novel addition was the use of phrase auto-correlation maps to show technical thrust areas based on phrase co-occurrence in Abstracts, and the use of phrase-phrase cross-correlation maps to show technical thrust areas based on phrase relations due to the sharing of common co-occurring phrases. The ˜400 most cited nanotechnology papers since 1991 were grouped, and their characteristics generated. Whereas the main analysis provided technical thrusts of all nanotechnology papers retrieved, analysis of the most cited papers allowed their characteristics to be displayed. Finally, most cited papers from selected time periods were extracted, along with all publications from those time periods, and the institutions and countries were compared based on their representation in the most cited documents list relative to their representation in the most publications list.

  5. Productivity and impact of astronomical facilities: Three years of publications and citation rates

    NASA Astrophysics Data System (ADS)

    Trimble, V.; Ceja, J. A.

    2008-07-01

    In calendar years 2001 to 2003, 20 journals of astronomy and astrophysics published 11 831 papers that reported or analyzed observations at wavelengths from meter radio to ultrahigh energy gamma rays. These were cited 161 556 times in the three calendar years following publication, according to the Science Citation Index/Web of Science, for an average of 13.66 citations per paper or 4.55 citations per paper per year. We examine these numbers as a function of subject matter, wavelength bands, journals, and individual telescopes used and explore a small subset of possible temporal trends, anomalies, and sources of uncertainty, including blockbuster journals, papers and facilities. Many of the results resemble qualitative expectations. There are hot topics (cosmology, exoplanets) and not so hot topics (binary stars, planetary nebulae). Papers reporting data from space are cited a bit more often, and ground-based radio papers a bit less often, than optical papers, while multi-wavelength ones do noticeably better than average. The total number of telescopes involved is surprisingly large, approximately 350 optical and infrared (mostly ground-based but including HST because of its long life), 144 radio facilities on about 100 sites (including WMAP and COBE and a few balloon-borne CMB experiments), and 105 space-based detectors (including satellites, interplanetary probes, things carried on rockets, balloons, the Shuttle, and so forth). The outstanding telescopes are generally both stable with time and predictable. HST and the VLA are responsible for the largest number of optical and radio papers respectively, but the most frequently cited optical papers come from SDSS (by a wide margin), Keck, and the AAT, while the JCMT, Parkes and (especially) CMB observatories lead the radio brigade. Among things that fly, leadership changes more quickly, as missions are launched, vigorously exploited, and turned off, sometimes achieving geostationary, suboceanic orbits. If you have a choice, large trumps small, but well-supported sites trump struggling ones by a comparable factor. And service to the community, in the form of catalogues and mission descriptions, is rewarded, at least in citation numbers, if not always in other ways.

    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.

    2015-01-01

    Over the last 50 years, the incidence of cervical cancer has dramatically decreased. However, health disparities in cervical cancer screening (CCS) persist for women from racial and ethnic minorities and those residing in rural and poor communities. For more than 45 years, federally funded health centers (HCs) have been providing comprehensive, culturally competent, and quality primary health care services to medically underserved communities and vulnerable populations. To enhance the quality of care and to ensure more women served at HCs are screened for cervical cancer, over eight HCs received funding to support patient-centered medical home (PCMH) transformation with goals to increase CCS rates. The study conducted a qualitative analysis using Atlas.ti software to describe the barriers and challenges to CCS and PCMH transformation, to identify potential solutions and opportunities, and to examine patterns in barriers and solutions proposed by HCs. Interrater reliability was assessed using Cohen's Kappa. The findings indicated that HCs more frequently described patient-level barriers to CCS, including demographic, cultural, and health belief/behavior factors. System-level barriers were the next commonly cited, particularly failure to use the full capability of electronic medical records (EMRs) and problems coordinating with external labs or providers. Provider-level barriers were least frequently cited. PMID:25685561

    To describe physicians' and patients' reasons for participating in office-based sales of dermatologic products. Survey data on the attitudes, opinions, and beliefs of dermatologists and their patients were analyzed. A market research study of office-based selling. Thirty dermatologists involved in direct selling from the office, 20 dermatologists not involved in direct selling, 22 patients who purchase products from their dermatologists' offices, and 25 office managers. The hypotheses of this study were formulated after the market research study had been done. The main outcome measure was the physicians' and patients' reported reasons for patients purchasing skin care products from dermatologists rather than from retail stores. "Trust" was the most frequent reason cited by physicians for patient purchases, while "physician knowledge" was the most frequent reason cited by the purchasing patients. The most common location to display the products was the waiting room (20 [67%] of the physicians). The most common types of products sold included glycolic acid products (15 [50%]), moisturizers (13 [43%]), sunscreens (12 [40%]), and alpha-hydroxy acid products other than glycolic acid (9 [30%]). The interaction between physicians who sell products in their offices and their patients is highlighted by 2 key elements of the physician-patient relationship: trust and physician knowledge.

    Text mining and other literature-based investigations can assist in identifying natural products for experimental and clinical research. This article details a method for systematically analyzing data derived from the classical Chinese medical literature. We present the results of electronic searches of Zhong Hua Yi Dian ("Encyclopaedia of Traditional Chinese Medicine"), a CD of 1000 premodern (before 1950) medical books, for single herbs, and other natural products used for dementia, memory disorders, and memory improvement. This review explores how the terminology for these disorders has changed over time and which herbs have been used more or less frequently, and compares the results from the premodern literature with the herbs indexed for memory disorders in a modern pharmacopoeia. The searches located 731 citations deriving from 127 different books written between ca. 188 ad and ca. 1920. Of the 110 different natural products identified, those most frequently cited for forgetfulness were yuan zhi (Polygala tenuifolia), fu shen (Poria cocos), and chang pu (Acorus spp.), all of which have been cited repeatedly over the past 1800 years and appear among the 31 herbs indexed in a modern pharmacopoeia. By providing a complete, hierarchically organized list of herbs for a specific disorder, this approach can assist researchers in selecting herbs for research. Copyright © 2013.

    Recruitment to general practice is a major concern in many countries. Cross-national exploration of motivation for career choice and career satisfaction could help inform workforce planning. Our aim was to explore motivation for career choice and job satisfaction of GP trainees and newly qualified GPs (NQGP) across seven European countries. We surveyed GP trainees and recently qualified GPs in the Czech Republic, Denmark, Germany, Italy, Norway, Portugal and the United Kingdom using a web-based questionnaire. The number of individuals who responded was 3722 (2533 GP trainees; 1189 NQGP). The most frequently cited reasons for choosing GP were 'compatibility with family life' (59.5%), 'challenging medically broad discipline' (58.9%), 'individual approach to people' (40.1%), 'holistic approach' (37.8%) and 'autonomy and independence' (30.4%). Despite differences in workload, work-life balance and earnings, overall job satisfaction was high, with over 80% saying that they would choose to be a doctor again; of these 78.4% would choose to be a GP again. In our sample reasons for choosing general practice as a career were strongly positive, with compatibility with family life the most frequently cited reason overall. This has implications for workforce planning. Further qualitative studies are needed to explore issues raised in more detail.

  12. Accuracy of cited “facts” in medical research articles: A review of study methodology and recalculation of quotation error rate

    PubMed Central

    2017-01-01

    Previous reviews estimated that approximately 20 to 25% of assertions cited from original research articles, or “facts,” are inaccurately quoted in the medical literature. These reviews noted that the original studies were dissimilar and only began to compare the methods of the original studies. The aim of this review is to examine the methods of the original studies and provide a more specific rate of incorrectly cited assertions, or quotation errors, in original research articles published in medical journals. Additionally, the estimate of quotation errors calculated here is based on the ratio of quotation errors to quotations examined (a percent) rather than the more prevalent and weighted metric of quotation errors to the references selected. Overall, this resulted in a lower estimate of the quotation error rate in original medical research articles. A total of 15 studies met the criteria for inclusion in the primary quantitative analysis. Quotation errors were divided into two categories: content ("factual") or source (improper indirect citation) errors. Content errors were further subdivided into major and minor errors depending on the degree that the assertion differed from the original source. The rate of quotation errors recalculated here is 14.5% (10.5% to 18.6% at a 95% confidence interval). These content errors are predominantly, 64.8% (56.1% to 73.5% at a 95% confidence interval), major errors or cited assertions in which the referenced source either fails to substantiate, is unrelated to, or contradicts the assertion. Minor errors, which are an oversimplification, overgeneralization, or trivial inaccuracies, are 35.2% (26.5% to 43.9% at a 95% confidence interval). Additionally, improper secondary (or indirect) citations, which are distinguished from calculations of quotation accuracy, occur at a rate of 10.4% (3.4% to 17.5% at a 95% confidence interval).

    To study the most important metrics of publication in the field of reproductive medicine over the decade 2003-2012 to aid in discerning the clinical, social, and epidemiologic implications of this relatively new but rapidly emerging area in medical sciences. Bibliometric analysis of most-cited publications from Web of Science databases. Not applicable. None. None. Most productive and frequently cited investigators, institutions, and countries and specific areas of research, scientific collaborations, and comparison of the growth of reproductive medicine research compared with other areas of medical investigation such as obstetrics and gynecology and related science categories. We found that 90 investigators with more than 1,000 citations had jointly published 4,010 articles. A continued rise in the impact factor of reproductive medicine journals was seen. The number of publications in reproductive medicine grew more rapidly compared with other science categories. Presently 22% of highly cited articles in reproductive medicine research are published in journals belonging to science categories outside reproductive medicine. The most-cited study groups are situated in the Netherlands, Belgium, Spain, the United States, and the United Kingdom, and collaborative studies have been increasing. Reproductive medicine research and subsequent clinical development have attained scientific growth and maturity. High-quality research is increasingly being published in high-impact journals. The increase in (inter)national collaborations seems to be key to the field's success. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

    Objectives To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Design Bibliometric analysis. Study selection Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. Data sources To identify health science journals, results were refined using Ulrich’s database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Data extraction Resulting citations were thematically coded, and descriptive statistics were calculated. Results 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n=648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Conclusions Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia. PMID:24603564

The following journal metrics were analyzed from the journal's homepage and Web of Science Core Collection database: number of citable and noncitable articles; number of original articles supported by grants; editorial board members' countries; authors' countries; citing authors' countries; source titles of citing articles; impact factor; total citations; comparison of impact factor with 3 Science Citation Index Expanded journals; and Hirsch index (H-index). Of the total 392 articles, 378 were citable articles (96.4%). Of the total 282 original articles, 52 (18.4%) were supported by research grants. The editorial board members were from 13 countries. Authors were from 20 countries. The number of countries of citing authors was 66. The number of source titles of citing articles was more than 100. The total citations of CiOS have increased from 0 in 2009 to 374 in 2015. The impact factors without self-citations of CiOS were the greatest among 4 Asian journals in 2013 and 2014. The 2015 impact factor was calculated as 0.79 in January 2016. The H-index was 13. CiOS can be considered to have reached the level of top-notch journal in the orthopedic field based on journal metrics. The inclusion of the journal in PubMed Central appears to have increased international relevance of the journal.

  3. [Research barometer: how is research activity monitored and how is it compared?].

    Recent analyses place Danish health science with the highest scientific impact per investment and the greatest share of most-cited papers globally. Several fields have international top score impact implying that they achieve more frequent citing than the average (Matthew effect). This appears paradoxical in view of the drastic reductions in Danish research budgets through the last 20 years--and the concomitant switch from long-term government grants to short-term external/private funding implying that continuity is replaced by demands for prompt results. Danish health research has thus proved remarkably robust under the steady downward tendency, but it is doubtful how far it will withstand current policy without irreversible damage. The methodologies applied in assessment of the excellence of research become increasingly sophisticated. They are still not completely reliable. At present they are primarily retrospective. It is imperative that future instruments monitor the actual research position.

    This article includes a systematic review and citation analysis of the literature regarding sexual minority parent families, particularly attending to what theories have been used, and how. We consider the importance of theoretical frameworks for future research and implications for policy, practice, and law related to sexual minority parent families. Our review targets 30 highly cited studies located through Google Scholar (as an interdisciplinary search engine) and published within a specific timeframe (2005-2010). We highlight the dominant theoretical models employed across disciplines studying sexual minority parent families. Although the majority of studies reviewed referred to theoretical models or perspectives, explicit theoretical grounding was frequently lacking. Instead, the empirical work reviewed appeared to have a predominantly applied focus in addressing public debates on sexual minority parent families. We provide recommendations for how theory might be more fully integrated into the social science literature on sexual minority parents and their children.

    Simple Summary National Royal Society for the Prevention of Cruelty to Animals (RSPCA) shelter admission data were utilized to examine cats presented to Australian animal shelters and reasons for surrender. This study reports the most commonly cited reasons for an owner to surrender and found lower than expected sterilized cats. Abstract Despite high numbers of cats admitted to animal shelters annually, there is surprisingly little information available about the characteristics of these cats. In this study, we examined 195,387 admissions to 33 Australian RSPCA shelters and six friends of the RSPCA groups from July 2006 to June 2010. The aims of this study were to describe the numbers and characteristics of cats entering Australian RSPCA shelters, and to describe reasons for cat surrender. Data collected included shelter, state, admission source, age, gender, date of arrival, color, breed, reproductive status (sterilized or not prior to admission), feral status and surrender reason (if applicable). Most admissions were presented by members of the general public, as either stray animals or owner-surrenders, and more kittens were admitted than adults. Owner-related reasons were most commonly given for surrendering a cat to a shelter. The most frequently cited owner-related reason was accommodation (i.e., cats were not allowed). Importantly, although the percentage of admissions where the cat was previously sterilized (36%) was the highest of any shelter study reported to date, this was still lower than expected, particularly among owner-surrendered cats (47%). The percentage of admissions where the cat was previously sterilized was low even in jurisdictions that require mandatory sterilization. PMID:26999223

    Little is known about designing an effective residency curriculum for pediatric craniofacial surgery. This study elucidates the pediatric craniofacial curriculum of the Plastic Surgery In-Service Training Examination (PSITE) to facilitate knowledge acquisition during residency. Approximately, 6 consecutive PSITEs were reviewed for pediatric craniofacial questions (2010-2015). Subjects were categorized according to topics on the American Board of Plastic Surgery written board examination. Questions were categorized using an educational taxonomy model. Answer references were categorized by source and publication lag. Of 1174 PSITE questions, 147 tested pediatric craniofacial topics (12.5%). Questions appeared predominately in the Craniomaxillofacial section (83.0%, p < 0.001). The annual representation was stable more than 6 years (range: 10.2%-14.4%, p = 0.842). Question taxonomy favored interpretation (45.6%) and decision-making (40.8%) over recall (13.6%, p < 0.001) skills, and 41 questions had an associated image (27.9%) and most were photographic (76.7%, p < 0.001). The most frequently tested categories on the American Board of Plastic Surgery written examination content outline were craniofacial anomalies (23.5%), benign and malignant tumors (17.6%), and cleft lip and palate (12.5%). Overall, 80 unique journals were cited 304 times with a mean publication lag of 9.4 ± 10.9 years. Plastic and Reconstructive Surgery (34.5%) was the most cited journal (p < 0.001). These data may assist in designating core knowledge competency in pediatric craniofacial surgery for plastic surgery residents. A further understanding of PSITE utility for core knowledge competency in pediatric craniofacial surgery would be the focus of future work.

    To assess the reading habits and educational resources of primary care internal medicine residents for their ambulatory medicine education. Cross-sectional, multiprogram survey of primary care internal medicine residents. Second- and third-year residents on ambulatory care rotations at 9 primary care medicine programs (124 eligible residents; 71% response rate). Participants were asked open-ended and 5-point Likert-scaled questions about reading habits: time spent reading, preferred resources, and motivating and inhibiting factors. Participants reported reading medical topics for a mean of 4.3+/-3.0 SD hours weekly. Online-only sources were the most frequently utilized medical resource (mean Likert response 4.16+/-0.87). Respondents most commonly cited specific patients' cases (4.38+/-0.65) and preparation for talks (4.08+/-0.89) as motivating factors, and family responsibilities (3.99+/-0.65) and lack of motivation (3.93+/-0.81) as inhibiting factors. To stimulate residents' reading, residency programs should encourage patient- and case-based learning; require teaching assignments; and provide easy access to online curricula.

    Opt-in surveys are the most widespread method used to study participation in online communities, but produce biased results in the absence of adjustments for non-response. A 2008 survey conducted by the Wikimedia Foundation and United Nations University at Maastricht is the source of a frequently cited statistic that less than 13% of Wikipedia contributors are female. However, the same study suggested that only 39.9% of Wikipedia readers in the US were female - a finding contradicted by a representative survey of American adults by the Pew Research Center conducted less than two months later. Combining these two datasets through an application and extension of a propensity score estimation technique used to model survey non-response bias, we construct revised estimates, contingent on explicit assumptions, for several of the Wikimedia Foundation and United Nations University at Maastricht claims about Wikipedia editors. We estimate that the proportion of female US adult editors was 27.5% higher than the original study reported (22.7%, versus 17.8%), and that the total proportion of female editors was 26.8% higher (16.1%, versus 12.7%).

    Gynecomastia is a potential side effect of hormone therapy for prostate cancer. In large, randomized, placebo controlled studies approximately 50% or more of patients with prostate cancer experienced gynecomastia attributable to various mechanisms. Although it is mostly reported as mild to moderate, gynecomastia is one of the reasons most frequently cited for premature discontinuation of such treatment. Prophylactic radiotherapy and prophylactic tamoxifen have been shown to decrease the incidence of hormone-induced gynecomastia; nevertheless, there are still cases of refractory gynecomastia, and in these plastic surgery is needed for correction. Gynecomastia is a benign enlargement of the male breast, requiring no treatment unless it is a source of embarrassment and/or distress for the adolescent or man affected. The indications for surgical treatment of gynecomastia are founded on two main objectives: restoration of the male chest shape and diagnostic evaluation of suspected breast lesions. The authors believe that the complete circumareolar technique with no further scarring creates the best aesthetic results with fewer complications. When this is used in combination with liposuction very pleasing aesthetic results can be achieved.

    Marketing by the pharmaceutical industry affects doctors' prescribing habits. All pharmaceutical advertising received by nine doctors in two GP offices over a period of three months was collected. The advertising material was sorted by compound. For each compound, the advert with the highest number of references was selected. The cited references were obtained, and the claims in the adverts were assessed in terms of their consistency with the source data based on the provisions in the Norwegian regulations on pharmaceuticals. The references were also assessed with regard to the incidence of conflicts of interest among authors. The doctors received a total of 270 shipments of advertising for 46 different compounds. Altogether 95% of the 173 references cited in the 46 selected adverts could be obtained. The adverts contained a total of 156 claims. Of these, 56% were assessed as correct when compared to the source data and as having clinical relevance. Altogether 75% of the journal articles reported relevant conflicts of interest for the authors. About half the claims in the adverts were found to be correct and clinically relevant. These results concur with those from a methodologically identical study based on advertising material collected in 2004. The cited literature was of varying quality and often funded by the pharmaceutical companies. The findings indicate that the target group should be sceptical of this type of marketing.

    Objectives To assess the sources of publicly available evidence supporting withdrawal, revocation or suspension of marketing authorisations (‘regulatory actions’) due to safety reasons in the EU since 2012 and to investigate the time taken since initial marketing authorisation to reach these regulatory decisions. Setting This investigation examined the sources of evidence supporting 18 identified prescription medicinal products which underwent regulatory action due to safety reasons within the EU in the period 1 July 2012 to 31 December 2016. Results Eighteen single or combined active substances (‘medicinal products’) withdrawn, revoked or suspended within the EU for safety reasons between 2012 and 2016 met the inclusion criteria. Case reports were most commonly cited, supporting 94.4% of regulatory actions (n=17), followed by randomised controlled trial, meta-analyses, animal and in vitro, ex vivo or in silico study designs, each cited in 72.2% of regulatory actions (n=13). Epidemiological study designs were least commonly cited (n=8, 44.4%). Multiple sources of evidence contributed to 94.4% of regulatory decisions (n=17). Death was the most common adverse drug reaction leading to regulatory action (n=5; 27.8%), with four of these related to medication error or overdose. Median (IQR) time taken to reach a decision from the start of regulatory review was found to be 204.5 days (143, 535 days) and decreased across the study period. Duration of marketing prior to regulatory action, from the medicinal product’s authorisation date, increased across the period 2012–2016. Conclusions The sources of evidence supporting pharmacovigilance regulatory activities appear to have changed since implementation of Directive 2010/84/EU and Regulation (EU) No. 1235/2010. This, together with a small improvement in regulatory efficiency, suggests progress towards more rapid regulatory decisions based on more robust evidence. Future research should continue to monitor sources of evidence supporting regulatory decisions and the time taken to reach these decisions over time. PMID:29362275

    Scientific software is largely developed by individual scientists and represents a significant intellectual contribution to the field. As the scientific culture and funding agencies move towards an expectation that software be open-source, there is a corresponding need for mechanisms to cite software, both to provide credit and recognition to developers, and to aid in discoverability of software and scientific reproducibility. We assess the geodynamic modeling community's current citation practices by examining more than 300 predominantly self-reported publications utilizing scientific software in the past 5 years that is available through the Computational Infrastructure for Geodynamics (CIG). Preliminary results indicate that authors cite and attribute software either through citing (in rank order) peer-reviewed scientific publications, a user's manual, and/or a paper describing the software code. Attributions maybe found directly in the text, in acknowledgements, in figure captions, or in footnotes. What is considered citable varies widely. Citations predominantly lack software version numbers or persistent identifiers to find the software package. Versioning may be implied through reference to a versioned user manual. Authors sometimes report code features used and whether they have modified the code. As an open-source community, CIG requests that researchers contribute their modifications to the repository. However, such modifications may not be contributed back to a repository code branch, decreasing the chances of discoverability and reproducibility. Survey results through CIG's Software Attribution for Geoscience Applications (SAGA) project suggest that lack of knowledge, tools, and workflows to cite codes are barriers to effectively implement the emerging citation norms. Generated on-demand attributions on software landing pages and a prototype extensible plug-in to automatically generate attributions in codes are the first steps towards reproducibility.

    Since the first description of Guillain-Barré syndrome (GBS) 100 years ago, the concept of this syndrome has changed remarkably. The purpose of our study was to identify and characterize the most-cited articles that have contributed to advancing the understanding of GBS. Based on the database of Journal Citation Reports, we selected 554 journals that were considered as potential sources of reports on studies related to clinical neurology and general medicine. The Web of Science search tools were used to identify the most-cited articles relevant to GBS or other variants in the selected journals. Of the selected articles, 18 were review articles and the remainder were original articles or included only a few case series. Among the original articles, 13 described basic research associated with immunological pathogenesis involving anti-ganglioside antibodies. Most of the original studies (42/64, 66%) published after 1990 evaluated anti-ganglioside antibodies that mediated axonal GBS or Miller Fisher syndrome, with only a small number of the papers involving electrodiagnostic medicine (n = 4). Our bibliometric analysis has yielded a detailed list of the top-100 cited articles in the field of GBS. © 2016 Peripheral Nerve Society.

    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. Three source journals were identified based on established criteria, and cited references from each article published from 1997 to 1999 were analyzed. 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. 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.

    Occupational therapy, formally organized in the United States in 1917, is considered an allied health field. Mapping occupational therapy literature is part of a bibliometric project of the Medical Library Association's Nursing and Allied Health Resources Section's project for mapping the literature of allied health. Three core journals were selected from the years 1995 and 1996 and a determination was made of the extent to which the cited journal references were covered by standard indexing sources. Using Bradford's Law of Scattering three zones were created, each containing approximately one-third of the cited journal references. The results showed that three journals made up the first zone, 117 journals the second, and 657 the third. The most cited journal was the American Journal of Occupational Therapy. In the second zone, journals from twelve disciplines were identified. While MEDLINE provided the best overall indexing, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) was the only database that indexed the three most cited journals plus nine of the currently active titles in occupational therapy. MEDLINE could improve its coverage of occupational therapy by indexing the journals of the British, Canadian, and Australian national associations. PMID:10427431

    The purpose of this study was to examine how pre- and early adolescent (10-14 years old) children from a wide range of neighbourhoods interact with their local food environment (FE), with a focus on the foods and food sources they access and their locations. Children in this age group are developing independence and mobility within (and beyond) their home neighbourhoods but are somewhat geographically bound as they cannot yet drive. This research consists of qualitative interviews with 31 children (15 males, 16 females) aged 10-14 years living in socio-economically diverse neighbourhoods across Saskatoon, SK. A thematic analysis was conducted. Children's descriptions of what constitutes their neighbourhood FE were varied, ranging from a couple of city blocks to several kilometres from home. Children were familiar with the types of establishment that sell food within their perceived neighbourhood. When children purchased their own food they most frequently cited buying snacks such as ice cream, candy and slushes, and the majority of these purchases were made in convenience stores, gas stations and grocery stores. Few children reported frequenting fast-food or other restaurants without adults, and when they did it was usually to buy snacks such as French fries and ice cream rather than meals. Our results highlight the importance of interventions targeted to this age group, in which personal food choices were reported almost exclusively as being energy- but not nutrient-dense snack foods.

    In 1999, in Toledo, Ohio, an outbreak of gastroenteritis occurred among people who had attended a Christmas dinner banquet and had eaten food prepared by a local caterer. Overall, 93 of the 137 attendees (67.9 percent) reported illness. Eight sought medical care, and one was hospitalized. Case-control studies revealed that the illness was associated with eating tossed salad (odds ratio [OR] = 2.5, 95 percent confidence interval [CI] = 1.02-6.26). Eleven of 12 stool specimens that were taken from ill people tested positive for a Norwalk-like virus (NLV) but were negative for E. coli O157:H7, Salmonella, and Shigella. The primary source of the outbreak was not determined, but an infected food handler may have played a role in the transmission of the virus. The catering facility had been cited frequently for food safety and hygiene violations. None of the personnel or food handlers at this facility had been appropriately trained in safe food-handling practices, nor had the personnel at another local caterer that had prepared food items suspected of causing a multistate outbreak of NLVs. In Toledo, food service operations with trained personnel/food handlers received better inspection reports than food service operations without trained personnel and were less likely to contribute to foodborne outbreaks. Training of personnel and food handlers may be important for preventing outbreaks.

    Genetic testing of minors is controversial, as ethical considerations depend on multiple aspects of the particular disease and familial context. For melanoma, there is a well-established and avoidable environmental influence and a documented benefit of early detection. We surveyed 61 CDKN2A/p16 mutation-tested adults from two kindreds about their attitudes toward genetic testing of minors immediately posttesting and 2 years later. Overall, 86.9% expressed support of melanoma genetic testing of minors, with the importance of risk awareness (77.4%) and the likelihood of improved prevention and screening behaviors (69.8%) as the most frequently cited potential benefits. Among mutation carriers, 82.6% wanted genetic testing for their own children. These preferences remained stable over a 2-year period. Most respondents (62.3%) favored complete involvement of their children in genetic counseling and test reporting; 19.7% suggested that children be tested but not informed of the results. Concerns about inducing psychological distress or compromising children's decision autonomy were infrequently cited. Testing preferences did not vary by respondent age, gender, or melanoma history. Respondents strongly supported melanoma genetic testing of minors, with most citing improved health behavior as a likely outcome. We discuss options for melanoma genetic counseling and testing of minors.

    Maximizing fat loss while preserving lean tissue mass and function is a central goal of modern obesity treatments. A widely cited rule guiding expected loss of lean tissue as fat-free mass (FFM) states that approximately one-fourth of weight loss will be FFM (i.e., ΔFFM/ΔWeight = ~0.25) with the remaining three-fourths fat mass. This review examines the dynamic relations between FFM, fat mass, and weight changes that follow induction of negative energy balance with hypocaloric dieting and/or exercise. Historical developments in the field are traced with the “Quarter FFM Rule” used as a framework to examine evolving concepts on obesity tissue, excess weight, and what is often cited as “Forbes’ Rule”. Temporal effects in the fractional contribution of FFM to changes in body weight are examined as are lean tissue moderating effects such as aging, inactivity, and exercise that frequently accompany structured low-calorie diet weight loss protocols. Losses of lean tissue with dieting typically tend to be small, raising questions about study design, power, and applied measurement method reliability. Our review elicits important questions related to the fractional loss of lean tissues with dieting and provides a foundation for future research on this topic. PMID:24447775

  7. Red brome (Bromus rubens subsp. madritensis) in North America: Possible modes for early introductions, subsequent spread

    Although invasions by exotic plants have increased dramatically as human travel and commerce have increased, few have been comprehensively described. Understanding the patterns of invasive species spread over space and time will help guide management activities and policy. Tracing the earliest appearances of an exotic plant reveals likely sites of introduction, paving the way for genetic studies to quantify founder events and identify potential source populations. Red brome (Bromus madritensis subsp. rubens) is a Mediterranean winter annual grass that has invaded even relatively undisturbed areas of western North America, where it threatens native plant communities. This study used herbarium records and contemporary published accounts to trace the early introductions and subsequent spread of red brome in western North America. The results challenge the most frequently cited sources describing the early history of this grass and suggest three possible modes for early introductions: the California Gold Rush and Central Valley wheat, southern California shipping, and northern California sheep. Subsequent periods of most rapid spread into new areas, from 1930 to 1942, and of greatest spread into new regions, during the past 50 years, coincide with warm Pacific Decadal Oscillation regimes, which are linked to increased winter precipitation in the southwestern USA and northern Mexico. Global environmental change, including increased atmospheric CO2 levels and N deposition, may be contributing to the success of red brome, relative to native species.

    This study explored views of 566 Italian psychology students about schizophrenia. The most frequently cited causes were psychological traumas (68 %) and heredity (54 %). Thirty-three percent of students firmly believed that people with the condition could recover. Reporting heredity among the causes, and identifying schizophrenia were both associated with prognostic pessimism, greater confidence in pharmacological treatments and lower confidence in psychological treatments. Schizophrenia labeling was also associated with higher perception of unpredictability and dangerousness. Compared to first year students, fourth/fifth year students more frequently reported heredity among the causes, and were more pessimistic about schizophrenia recovery. Stigma topics should be included in future psychologists' education.

  9. Why do women take self-defense classes?

    Given the positive benefits of self-defense training for women, it is important to understand how women come to enroll in self-defense classes. Using data from a longitudinal study of university women, I explore the reasons women give for taking a self-defense class. I find that friends' recommendations, visions of the "possible selves" they could become, and fear of violence were the most frequently reported reasons; having experienced a past assault was rarely cited as a reason for enrolling. In addition, many women who had never enrolled in a self-defense class reported having considered doing so. I explore barriers to learning self-defense and find that logistical issues such as time, money, and availability of classes were the most frequently reported reasons for not enrolling.

    Objectives This study assessed influences on vaccination decisions among parents of young children and examined common vaccination information and advice sources. Methods Using panel samples of parents of children under 7 years, web-based surveys were conducted in 2012 (n = 2603) and 2014 (n = 2518). A vaccine decision-making typology (non-hesitant acceptors, hesitant acceptors, delayers, and refusers) was established and weighted population estimates of potential factors influencing parental vaccination decision (e.g., provider influence, source of information and advice) were computed by year and decision type. Results Delayers and refusers were more likely than acceptors to know someone whose child experienced a severe reaction to a vaccine or delayed/refused vaccine(s). High proportions of delayers (2012: 33.4%, 2014: 33.9%) and refusers (2012: 49.6%, 2014: 58.6%) reported selecting their healthcare provider based on whether the provider would allow them to delay/refuse vaccines. Providers were the most frequently reported trusted vaccine information source among all parents, though more often by acceptors than refusers (2012, 2014: p < 0.01). We found differing patterns of provider advice-seeking and internet as a reliable vaccine information source by group. Among those who had considered delay/refusal, trust in their healthcare provider's advice was the most common reason cited for their decision reversal. Conclusions for Practice Provider trust and communication along with varying degrees of personal-network influences likely contribute to immunization decisions of parents. Vaccine hesitant parents often seek providers amenable to accommodating their vaccine beliefs. Providers may benefit from vaccine communication training as their recommendations may influence hesitant parents to immunize their children.

    To better focus efforts in recruiting psychoanalytic candidates, current candidates' demographics, practice patterns, and satisfaction with psychoanalytic training were investigated. An anonymous web-based survey was distributed by e-mail to all candidates subscribing to the affiliate member e-mail list in 2009-2010. Surveys were completed by 226 of 565 affiliate members, for a return rate of 40%. The majority of respondents were women 45 to 64 years of age, married, with a doctoral degree, in private practice, with an annual household income of over $100,000. Most candidates devoted 11 to 30 hours a week to training and had no analysts or candidates in their workplace. Almost half had considered training for more than four years before matriculation, with financial issues cited most frequently as delaying entry. Over 80% of respondents were satisfied with their training. The most frequently cited reasons for dissatisfaction were a negative institute atmosphere, concerns about teaching or the curriculum, and difficulty finding cases. Candidates in training for eight years or more accounted for almost 20% of the group and were more often dissatisfied with training. This study demonstrates that the majority of current candidates are satisfied with training but suggests that recruitment may become increasingly difficult unless factors related to time, cost, case finding, graduation requirements, and institute atmosphere can be addressed.

    We have compiled a list of the 50 most-cited original articles in the field of vascular surgery during the last 25 years to highlight the important changes in practice that have occurred during this interval and provide surgical trainees in vascular surgery ready access to such influential articles. A Web of Knowledge Citation Index Search was performed in December 2013 for the most-cited journal articles in the discipline of vascular surgery. We searched the term "vascular" in the cited reference search area and then further narrowed our results to exclude all categories except "surgery," "general internal medicine," and "cardiac/cardiovascular systems." We included only documents labeled as "articles" and those published in English. Articles dealing with cardiac surgery, interventional cardiology, and cardiovascular biology were excluded. Our search period was from January 1, 1988, through December 3, 2013. The 50 most frequently cited works were chosen, and a citation density was calculated for each, reflecting the average number of citations each received per year since publication. The articles were then sorted into a defined category, based on the clinical subject to which they pertained. The Citation Index Search resulted 80,379 articles, of which the top 50 were indexed and organized according to their citation density and area within the scope of clinical vascular surgery. The number of citations ranged from 218 to 3593. The median citation density was 50.2 (range, 11.3-201.3). This report is a representation of the most-cited original publications in the field of clinical vascular surgery during the last 25 years. This is an effort to highlight the seminal works that have shaped the discipline of vascular surgery as well as to provide a concise reference list for the surgical trainee in the process of his or her education.

    To identify 100 top-cited articles published in periodontal journals and analyse the research trends by using citation analysis. 100 top-cited articles published in periodontal journals were retrieved by searching the database of the ISI Web of Science and Journal Citation reports. For each article, the following principal bibliometric parameters: authorship, geographic and institute origin, manuscript type, study design, scope of study, and citation count of each time period were analysed from 1965 to 2015. The identified 100 top-cited articles were retrieved from five periodontal journals and citation counts were recorded between 262 and 1,693 times. For the institute of origin, the most productive institute, in terms of the number of 100 top-cited articles published, was the University of Gothenburg (Sweden) (n = 19), followed by the Forsyth Dental Center (USA) (n = 15). Most manuscripts were original research (n = 74), and the inflammatory periodontal disease (n = 59) was the most frequent topic studied. Interestingly, the trend of increase average citation reached significance for implantology (β = 26.75, P = 0.003) and systemic interactions (β = 29.83, P = 0.005), but not for inflammatory disease (β = -10.30, P = 0.248) and tissue regeneration (β = 9.04, P = 0.081). By using multivariable linear regression in a generalised linear model, suitable published journal (Journal of Clinical Periodontology), geographic regions (Europe), more intense international collaboration, adequate manuscript type (review article) and study design (systematic review) could be attributed to escalating average citation counts in implantology (all P < 0.05). However, for systemic interactions, only geographic region and study design were significantly associated with the increasing citation trend. These principal bibliometric characteristics revealed escalated trends in average citation count in implantology throughout time. Conflict-of-interest statement The authors have stated explicitly that there are no conflicts of interest in connection with this article. The study was self-funded by the authors and their institution.

    To identify global research trends in the use of acupuncture to treat cerebral infarction. 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. 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. articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. (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. 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. 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.

  19. dCITE: Measuring Necessary Cladistic Information Can Help You Reduce Polytomy Artefacts in Trees.

    Wise, Michael J

    2016-01-01

    Biologists regularly create phylogenetic trees to better understand the evolutionary origins of their species of interest, and often use genomes as their data source. However, as more and more incomplete genomes are published, in many cases it may not be possible to compute genome-based phylogenetic trees due to large gaps in the assembled sequences. In addition, comparison of complete genomes may not even be desirable due to the presence of horizontally acquired and homologous genes. A decision must therefore be made about which gene, or gene combinations, should be used to compute a tree. Deflated Cladistic Information based on Total Entropy (dCITE) is proposed as an easily computed metric for measuring the cladistic information in multiple sequence alignments representing a range of taxa, without the need to first compute the corresponding trees. dCITE scores can be used to rank candidate genes or decide whether input sequences provide insufficient cladistic information, making artefactual polytomies more likely. The dCITE method can be applied to protein, nucleotide or encoded phenotypic data, so can be used to select which data-type is most appropriate, given the choice. In a series of experiments the dCITE method was compared with related measures. Then, as a practical demonstration, the ideas developed in the paper were applied to a dataset representing species from the order Campylobacterales; trees based on sequence combinations, selected on the basis of their dCITE scores, were compared with a tree constructed to mimic Multi-Locus Sequence Typing (MLST) combinations of fragments. We see that the greater the dCITE score the more likely it is that the computed phylogenetic tree will be free of artefactual polytomies. Secondly, cladistic information saturates, beyond which little additional cladistic information can be obtained by adding additional sequences. Finally, sequences with high cladistic information produce more consistent trees for the same taxa.

    Glioma is the most common intracranial tumor and has a poor patient prognosis. The presence of brain tumor stem cells was gradually being understood and recognized, which might be beneficial for the treatment of glioma. To use bibliometric indexes to track study focuses on glioma stem cell, and to investigate the relationships among geographic origin, impact factors, and highly cited articles indexed in Web of Science. A list of citation classics for glioma stem cells was generated by searching the database of Web of Science-Expanded using the terms "glioma stem cell" or "glioma, stem cell" or "brain tumor stem cell". The top 63 cited research articles which were cited more than 100 times were retrieved by reading the abstract or full text if needed. Each eligible article was reviewed for basic information on subject categories, country of origin, journals, authors, and source of journals. Inclusive criteria: (1) articles in the field of glioma stem cells which was cited more than 100 times; (2) fundamental research on humans or animals, clinical trials and case reports; (3) research article; (4) year of publication: 1899-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles needing to be manually searched or accessed only by telephone; (2) unpublished articles; and (3) reviews, conference proceedings, as well as corrected papers. Of 2 040 articles published, the 63 top-cited articles were published between 1992 and 2010. The number of citations ranged from 100 to 1 754, with a mean of 280 citations per article. These citation classics came from nineteen countries, of which 46 articles came from the United States. Duke University and University of California, San Francisco led the list of classics with seven papers each. The 63 top-cited articles were published in 28 journals, predominantly Cancer Research and Cancer Cell, followed by Cell Stem Cell and Nature. Our bibliometric analysis provides a historical perspective on the progress of glioma stem cell research. Articles originating from outstanding institutions of the United States and published in high-impact journals are most likely to be cited.

    Objective The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Methods Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. Results The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using 192Ir (26 centers) or 60Co (two centers). Among the 26 centers using 192Ir sources, 11 treated fewer than 40 patients per year. In the two centers using 60Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. Conclusion The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy. PMID:27102244

    The 2001 edition of the Journal Citation Reports (JCR) includes only 13 Spanish medical journals. The impact factor (IF) of the rest of Spanish medical journals is unknown. The aim of this study is to determine the IF of the main Spanish medical journals, taking also into account the references from journals not covered by the SCI. A set of 87 Spanish medical journals was selected from the national database IME and other international databases. All citable articles published in these journals in 2001 were analyzed, extracting their bibliographic references to articles published in 1999, 2000 and 2001. The indicators obtained for each journal were the number of cites, the IF and the immediacy index. Among the 87 source journals, 74 were not included in the JCR. From them, 5,388 bibliographic references were examined, identifying the journals cited. Final indicators were obtained adding these results to the ones obtained by using the Science Citation Index. The most cited journal was Medicina Clinica (768 cites), and the highest IF were attained by Histology and Histopathology (IF = 1.866), International Journal of Developmental Biology (IF = 1.654) and Medicina Clinica (IF = 1.125). This work has permitted to obtain the IF of 87 Spanish medical journals. Already detected in previous works, the leadership of the journal Medicina Clinica in Spanish medicine is confirmed. Spanish medical journals published in English have received a small number of cites from the ones published in Spanish. A low impact factor is not necessarily related to lack of quality, merit or relevance.

    To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Bibliometric analysis. Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. To identify health science journals, results were refined using Ulrich's database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Resulting citations were thematically coded, and descriptive statistics were calculated. 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n = 648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia.

    The role of photochemistry in the budget of tropospheric ozone is studied. Measurements of O3, NO, CO, H2O vapor, and temperature obtained during the fall of 1983 during the GTE/CITE project over the eastern and central North Pacific Ocean are analyzed. The effect of altitude on the measurements is discussed. The analysis reveals a correlation between ozone and NO levels; both increase in concentration and variability with altitude. It is observed that an additional source of secondary importance associated wih CO-rich air parcels exists. A photochemical model is utilized to calculate the net rate of ozone production by photochemical reactions. A net photochemical source of ozone in the free troposphere and a net sink in the boundary layer are detected. The relation between the ozone source in the free troposphere and NO is examined. It is estimated that photochemistry provides a net ozone source to the free troposphere overlying the eastern and central North Pacific Ocean of about 5 x 10 to the 10th molecules/sq cm sec and a net sink of ozone to the boundary layer overlying this region of about 3 x 10 to the 10th molecules/sq cm sec.

    2002-01-01

    We present a reduction pipeline for CCD (charge-coupled device) images which was built to search for variable sources in highly crowded fields like the M 31 bulge and to handle extensive databases due to large time series. We describe all steps of the standard reduction in detail with emphasis on the realisation of per pixel error propagation: Bias correction, treatment of bad pixels, flatfielding, and filtering of cosmic rays. The problems of conservation of PSF (point spread function) and error propagation in our image alignment procedure as well as the detection algorithm for variable sources are discussed: we build difference images via image convolution with a technique called OIS (optimal image subtraction, Alard & Lupton \\cite{1998ApJ...503..325A}), proceed with an automatic detection of variable sources in noise dominated images and finally apply a PSF-fitting, relative photometry to the sources found. For the WeCAPP project (Riffeser et al. \\cite{2001A&A...0000..00R}) we achieve 3sigma detections for variable sources with an apparent brightness of e.g. m = 24.9;mag at their minimum and a variation of Delta m = 2.4;mag (or m = 21.9;mag brightness minimum and a variation of Delta m = 0.6;mag) on a background signal of 18.1;mag/arcsec2 based on a 500;s exposure with 1.5;arcsec seeing at a 1.2;m telescope. The complete per pixel error propagation allows us to give accurate errors for each measurement.

    The objectives of this study were to determine prevalence and types of treatments used by patients with recurrent aphthous stomatitis (RAS), and to study the sources of information about treatments used. The study was a cross-sectional survey. The participants were 530 students who had a history of RAS and were studying at the University of Jordan, Amman. Of the 530 patients, 267 (50.4%) have attempted treatment of RAS. Of those who treated RAS, 86 (32.2%) have used alternative treatments (ATs). Topical anaesthetics/analgesics, antiseptic mouthwashes, and topical steroids represented 84.5% of the conventional medicines used. Of those who used ATs, 34 (39.5%) used tahini, 21 (24.4%) used salt/salt and warm water mouthrinse, and 7 (8.1%) used lemon/lemon salt. The tendency to treat RAS or not was not significantly affected by sociodemographic variables, but ATs were more significantly used by students living in rural areas. Relatives were the most frequently cited source of information about treatment (44.6%), followed by medical practitioners (22.9%), and only 9.4% sought treatment advice from dentists. Interestingly, 7% of the ATs were recommended by health care providers and 38.7% of the conventional treatments were recommended by non-health-care providers including 15 cases of topical steroids. This survey revealed a high prevalence of ATs use among Jordanian patients with RAS. There is a need to educate patients with RAS on the treatment options available to reduce their distress and to improve their quality of life. Health care providers such as medical practitioners and pharmacists are frequently consulted by patients with oral lesions, so they should provide patients with better education in the diagnosis and treatment of oral diseases. Randomized clinical trials are needed to examine the potential usefulness of the commonly used ATs in this study such as tahini/sesame oil in the treatment of RAS.

  19. Radiography student perceptions of clinical stressors.

    Technological change and the increasingly rapid pace of life in the United States and globally have contributed to increased levels of stress and burnout experienced by workers and their families. Although studies are available on the levels of workplace stress and burnout affecting radiographers, little to no research has been conducted to assess the stressors encountered by radiography students in the clinical environment. This study was designed to pinpoint the primary sources of stress for radiography students and to determine the most effective measures to alleviate the stress that students experience in the clinical environment. It also sought to identify the clinical activities and practices that enhance learning. A convenience sample of radiography students attending an Association of Collegiate Educators in Radiologic Technology meeting was surveyed. Students were asked to rank their greatest stressors in the clinical environment, the most desired qualities in a clinical instructor and clinical environment, and the clinical practices and activities that best enhance their learning. Descriptive statistics were used to report the results. Data were collected for 82 first-year and second-year students. Students identified 7 primary clinical stressors: fear of making a mistake/repeat, feeling unprepared/inexperienced, intimidation by staff and by instructors, difficult/critical patients, hurtful criticism, too much supervision and negative responses to questions/requests for help. Students indicated that more frequent feedback, availability of the clinical instructor and other staff, assurance that mistakes happen and the opportunity to make mistakes were clinical practices that eased stress. The majority of students cited hands-on learning and repetition as the clinical activities that most reinforced their learning. Summary Radiography students in this survey experience some of the same clinical stressors as radiographers and other allied health workers, although the source of stress may be different. Factors that promote an optimum clinical learning environment for students include instructor availability, opportunities to practice skills and make mistakes, frequent performance feedback and assurance that mistakes happen.

  20. Impact Factors and Prediction of Popular Topics in a Journal.

    PubMed

    Nielsen, M B; Seitz, K

    2016-08-01

    The impact factor (IF) for 2015 was recently released and this could be the time to once again reflect on its use as a metric of a journal. Problems and concerns regarding the IF have been addressed extensively elsewhere 1 2. The principle of the IF for a given year is that it represents the average number of citations of articles published in the journal in the two previous years.While authors frequently cite the IF as a determining factor for submission, the IF does not predict how many times individual articles will be cited. In a study from a peer-reviewed cardiovascular journal, nearly half of all published articles were poorly cited, i. e., less than five citations in five years 3. A similar percentage seems to apply to our journal. In nearly all journals we estimate that the majority of citations relate to a minority of the articles. Some articles are never cited. 13 % of the articles published in our journal from 2010 to 2013 have never been cited. Even authors of poorly cited articles benefit from the IF since many institutions use the combined impact factors of their published papers to measure research activity and this may be reflected in their research budgets.The competition for the printed pages in the six annual issues of Ultraschall in der Medizin/European Journal of Ultrasound (UiM/EJU) has resulted in high rejection rates (between 80 % and 90 %). One negative review with recommendation of major revision may therefore result in rejection. Peer-review fraud where the submitting author listed recommended reviewers with fake email addresses supplying fabricated peer reviews has recently been described in the New England Journal of Medicine 4. Some of the editors of our journal believe they have experienced this as well. Fabricating reviews in order to get a high IF for an article is to be considered fraud and is inexcusable.One aspect of using impact factors as a measure of the quality of a journal is that the IF only goes back two years. There may be differences between journals for different medical specialties since the citations in some areas seem to "burn out" within a few years while some articles continue to be cited even after several years. Therefore, a citation window that is longer than 2 years has been proposed 5.For this editorial we took a look at the 60 articles published in UiM/EJU in 2010. Half of them were no longer being cited in 2015. However, 10 articles were cited more than 5 times in 2015, and 5 of these were cited more than 10 times 6 7 8 9 10. It therefore seems that many of our articles have a long scientific life and generate more citations than indicated by the IF. Moreover, some articles have the highest number of citations after three years when they are no longer contributing to the impact factor. The most frequently cited articles from 2010 were multicenter studies, recommendations, and papers on hot topics like contrast-enhanced ultrasound (CEUS) and elastography, but it should be noted that there were also articles on the same topics that were poorly cited.The same trending topics continued into 2013 now topped by European guidelines and recommendations 11 12 13. 9 of the 10 most cited articles we published in 2014 were on CEUS or elastography 14 15 16 17 18 19 20 21 22, but the most cited article from that year so far has been on peripheral nerves 23. Surprisingly many good scientific papers on obstetrics/fetal US and musculoskeletal US have low citation rates 24 25 26. Our predictions for 2016 based on the topics of submitted articles in the last 12 months are that CEUS and elastography will continue to be popular topics.It is also worth mentioning that there can be a discrepancy between which titles are cited and which are accessed online. In addition to international guidelines, our CME articles are usually popular according to online access. CME articles are well established educational papers but they are rarely cited for the IF. Looking at the most read full-text recent articles on our journal's website shows that multicenter studies as well as recommendations backed by a national society or by the EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) are still important 27 28 29 30 31 32 33. Upcoming important topics appear to be pediatric use of CEUS, simulation training and the introduction of ultrasound to medical students 34 35 36 37. Some of these are also backed by EFSUMB.A recent paper on the IF of radiology journals found that subspecialty radiology journals had a higher IF than general radiology journals 38. This could prove a challenge to interdisciplinary journals like ours but we take pride in continuing to cover all aspects of ultrasound in more than 15 fields.The distribution between reviews, original articles and case reports in a journal is worth addressing. An important aspect of a journal is the publication of original scientific research articles. CME articles, pictorials and letters are important for other reasons but are cited at a lower rate. The value of case reports with regard to the IF is low since they are rarely cited 39 and we have observed that some journals have abandoned the publication of case reports, thus leaving them to spin-off journals. The rationale is that keeping case reports in a journal will only increase the denominator, thereby decreasing the IF 39. At our journal we have seen a decline in case report submissions but still want to publish them and even put one case on the front cover of every issue. Case reports still hold an educational value 40 and are important to our readers.In conclusion, a healthy mix of original articles, CME articles, reviews and case reports combined with a few international guidelines and recommendations is important to UIM/EJU. Although we see popular topics like CEUS and elastography, it is not possible to predict which articles will be read or even cited based on the topic, with multicenter studies being the exception. © Georg Thieme Verlag KG Stuttgart · New York.

    The French physicist Georges Sagnac is nowdays frequently cited by the engineers who work on devices such as ring-laser gyroscopes. These systems operate on the principle of the Sagnac effect. It is less known that Sagnac was a strong opponent to the theory of special relativity proposed by Albert Einstein. He set up his experiment to prove the existence of the aether discarded by the Einsteinian relativity. An accurate explanation of the phenomenon was provided by Paul Langevin in 1921.

    Abstract The Injury and Illness Prevention Program (IIPP) requirement has been the most frequently cited standard in California workplace health and safety inspections almost every year since it became effective in July 1991. Every workplace safety inspection must assess compliance with the IIPP. This article presents the results of an evaluation of the IIPP's effects on worker injuries in California and should inform policy both in California and in the federal Occupational Safety and Health Administration (OSHA) program, which has made the adoption of a similar national requirement a top priority. Using data from the Workers' Compensation Information System, OSHA Data Initiative statistics, and Workers' Compensation Insurance Rating Bureau of California reports on medical and indemnity claims from single-establishment firms, the evaluation team analyzed the impact of citations for violations of the IIPP on safety performance by (1) using the number of citations as a measure of effectiveness and (2) assessing the number of establishments that were cited for noncompliance and then came into compliance. They found that enforcement of the IIPP appears to prevent injuries only when inspectors cite firms for violations of specific subsections of that standard. Eighty percent of the citations of the IIPP by the California Division of Occupational Safety and Health program are for only a different section, the one that requires employers to have a written IIPP. The specific subsections refer to the provisions that mandate surveying and fixing hazards, investigating the causes of injuries, and training employees to work safely. Because about 25 percent of all inspections cite the IIPP, citations of the specific subsections occur in about 5 percent of all inspections. In those inspections, the total recordable injury rate falls by more than 20 percent in the two years following the inspection. PMID:28083238

    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.

    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

    The panoply of products used by hair care professionals to wash, dye, shape and beautify hair is not entirely free from adverse events. Such effects consist mainly of irritation dermatitis and allergic contact eczema affecting the scalp, as well as the back and front of the neck, the forehead and periorbital areas, and the cheeks. The most frequently cited allergens include paraphenylenediamine (PPD) in hair dyes, glycerol monothioglycolate (GMTG) in acid perm lotions, and ammonium persulphate in hair lighteners (the latter substance being responsible primarily for contact urticaria). However, care should also be paid to other allergens such as cocamidopropyl betaine among surfactants, as well as certain components in hair formulations such as preservatives and fragrances (as well as minoxidil, frequently used by patients).

    2003-09-01

    Gastritis--inflammation of the stomach--is a frequently cited differential yet rarely characterized diagnosis in cases of canine anorexia and vomiting. Although the list of rule-outs for acute or chronic gastritis is extensive, a review of the veterinary literature reveals fewer than 15 articles that have focused on clinical cases of canine gastritis over the last 25 years. The dog frequently appears in the human literature as an experimentally manipulated model for the study of endoscopic techniques or the effect of medications on gastric mucosa. In the veterinary patient, cases of acute gastritis are rarely pursued with the complete diagnostic armamentarium, and cases of chronic gastritis are rarely found to occur as an entity isolated from the rest of the gastrointestinal tract. This article focuses on those findings most clinically relevant to cases of canine gastritis in veterinary medicine.

    This pilot study assessed an electronic health diary method designed to collect data about critical health incidents experienced by college students who have chronic health conditions. Nine university students with chronic medical conditions were recruited to complete a series of e-mail-based surveys, sent once every 3 days across the fall 2014 semester. In each survey, participants described a health-related incident that occurred within the past day and cited resources that helped or could have helped in that situation. They completed follow-up interviews and ranked the importance of cited resources. The diary completion rate was 78.3% (141/180). Most frequently affected management areas were activities (61.3%), monitoring (34.9%), and problem-solving (34.3%). Resources considered helpful included situational knowledge, campus health professionals, peer support, and relaxation opportunities. Prompted health incidents diary method achieved a high completion rate and provided data that could be useful for college health researchers and practitioners.

    Using traditional bibliometric indices such as the well-known journal impact factor (IFAC), as well as other more recently developed measures like the (journal) h-index and modifications, we assessed the impact of most prolific scientific journals in the field of animal and dairy science. To achieve this end, we performed a detailed investigation on the evaluation of journals quality, using a total of 50 journals selected from the category of "Agriculture, Dairy & Animal Science" included in the Thomson Reuters' (formerly Institute of Scientific Information, ISI) Web of Science. Our analysis showed that among the top journals in the field are the Journal of Dairy Research, the Journal of Dairy Science, and the Journal of Animal Science. In particular, the Journal of Animal Science, the most productive and frequently cited journal, has shown rapid development, especially in recent years. The majority of the top-tier, highly cited articles are those associated with the description of statistical methodology and the standard chemical analytical methodologies.

    This study used administrative data to identify characteristics of frequent users of Singapore's largest specialized psychiatric emergency department (ED). Qualitative interviews were conducted to understand staff opinions of frequent visitors. Data were from administrative records of all adult visits to the ED (N=16,123 visits of 10,108 individual users) in 2014. Random-effects logistic regressions were used to identify demographic and diagnostic characteristics of frequent visitors. To facilitate interpretation of administrative data in a convergent mixed-methods study design, interviews were conducted with 26 service providers who worked in the ED. Frequent use was defined as five or more visits in 2014. This cutoff distinguished the top 3% of users (N=331), and this group accounted for 16% of service use. Frequent users were more likely to have a diagnosis of a psychotic disorder, personality disorder, or alcohol use disorder. Service provider groups (for example, physicians, nurses, and assistants) described similar groups of frequent users and noted that frequent use was related to lack of social supports outside the hospital and feelings of belonging within it. The most frequently cited challenges were managing intoxicated service seekers, managing expectations for admission, and dealing with threats of self-harm. The profiles of frequent ED users in Singapore resembled those reported in other large urban centers. The opinions of service providers and their reactions to difficult situations were similar to those of providers in nonpsychiatric settings. The service providers' perspectives highlight how societal pressures influence the way in which individuals with mental illnesses use services.

    Researchers turn to citation tracking to find the most influential articles for a particular topic and to see how often their own published papers are cited. For years researchers looking for this type of information had only one resource to consult: the Web of Science from Thomson Scientific. In 2004 two competitors emerged--Scopus from Elsevier and Google Scholar from Google. The research reported here uses citation analysis in an observational study examining these three databases; comparing citation counts for articles from two disciplines (oncology and condensed matter physics) and two years (1993 and 2003) to test the hypothesis that the different scholarly publication coverage provided by the three search tools will lead to different citation counts from each. Eleven journal titles with varying impact factors were selected from each discipline (oncology and condensed matter physics) using the Journal Citation Reports (JCR). All articles published in the selected titles were retrieved for the years 1993 and 2003, and a stratified random sample of articles was chosen, resulting in four sets of articles. During the week of November 7-12, 2005, the citation counts for each research article were extracted from the three sources. The actual citing references for a subset of the articles published in 2003 were also gathered from each of the three sources. For oncology 1993 Web of Science returned the highest average number of citations, 45.3. Scopus returned the highest average number of citations (8.9) for oncology 2003. Web of Science returned the highest number of citations for condensed matter physics 1993 and 2003 (22.5 and 3.9 respectively). The data showed a significant difference in the mean citation rates between all pairs of resources except between Google Scholar and Scopus for condensed matter physics 2003. For articles published in 2003 Google Scholar returned the largest amount of unique citing material for oncology and Web of Science returned the most for condensed matter physics. This study did not identify any one of these three resources as the answer to all citation tracking needs. Scopus showed strength in providing citing literature for current (2003) oncology articles, while Web of Science produced more citing material for 2003 and 1993 condensed matter physics, and 1993 oncology articles. All three tools returned some unique material. Our data indicate that the question of which tool provides the most complete set of citing literature may depend on the subject and publication year of a given article.

    To identify healthy food (HF) purchase habits and intake of fruits and vegetables (FV) in parents responsible for grocery shopping for their families. Survey with mothers and fathers (n = 216) of children aged 7-10 years in Brazil. Grocery purchases occurred mostly at supermarkets. Purchase of HF was considered to be frequent by 80% of parents, who cited FV as main examples of HF. The more frequent the reported purchase was of HF, the higher was the prevalence of regular consumption of FV (P = .002). Only 34% of respondents reported weekly intakes that could be classified as regular. Perceived frequent shopping for healthy foods was positively associated with regular consumption of FV but a gap between perception and behavior was identified. Nutrition education strategies need to go beyond a merely informative role and take consumers' opinions and points of view into consideration to become truly effective.

    Descriptive data characterizing the frequency of various chief complaints and presenting symptomatology in children with hyperthyroidism are lacking. Furthermore, difficulties in recognizing atypical presentations may delay diagnosis and increase morbidity. We performed a retrospective review of the medical records of 76 children with hyperthyroidism to characterize their chief complaints at initial presentation to care and document other presenting symptomatology. Cardiac symptoms were the most frequent chief complaint, accounting for 23% of presenting complaints. Major mood and behavior disturbances were also frequently present (21%), but were infrequently cited as the chief complaint (6%). This study is the first to describe chief complaints separately from the other signs and symptoms of hyperthyroidism noted at the time of presentation to medical attention. Cardiac complaints were the most common: however, complaints associated with behavioral and mood disorders also occurred frequently. Clinicians should be aware of these presentations so that hyperthyroidism is diagnosed promptly to avoid morbidity associated with delayed diagnosis.

    Casual video games (CVGs) are becoming increasingly popular among middle-aged and older adults, yet there are few studies documenting why adults of different ages play these games, what benefits they perceive, and how regularly they play. The present study compared the online survey responses of 10,308 adults ranging from 18 to 80 years of age to questions regarding PopCap's popular free online game, Bejeweled Blitz (BJB). All respondents cited playing against friends as their main reason for playing. However, there were differences by age in the second most frequently cited reason. Middle-aged adults cited stress relief, and older adults reported that they seek the game's challenges. As a result of playing CVGs, younger adults noted that they felt sharper and experienced improved memory; older adults were more likely to feel that their visuospatial skills and response time benefited. Adults aged 60 and older had heavier patterns of game play than did adults under the age of 60 years. A significant number of respondents (14.7%) spontaneously noted that they felt that BJB had addictive qualities. CVG players seem to be drawn into this activity by its social nature and to a certain extent by its reinforcing properties. Once involved, however, they believe that they derive a number of benefits that, for older adults, appear to offset declines in age-sensitive cognitive functions.

    Objective Human pluripotent stem cells are self-renewing cells with the ability to differentiate into a variety of cells and are viewed to have great potential in the field of regenerative medicine. Research in pluripotent stem cells holds great promise for patient specific therapy in various diseases. In this study, pluripotent stem cell articles published from 1991 to 2012 were screened and retrieved from Science Citation Index Expanded (SCI-EXPANDED). Materials and Methods In this retrospective study, the publication trend, citation trends for top articles, distributions of journals and Web of Science categories were analyzed. Five bibliometric indicators including total articles, independent articles, collaborative articles, first author articles, and corresponding author articles were applied to compare publications between countries and institutions. Results The impact of top articles changed from year to year. Top cited articles in previous publication years were not the same as recent years. "Induced pluripotent stem cell (s)" and "embryonic stem cell (s)" were the most used author keywords in pluripotent stem cell research. In addition, the winner of the Nobel Prize in physiology or medicine in 2012, Prof. Shinya Yamanaka, published four of the top ten most frequently cited articles. Conclusion The comprehensive analysis of highly cited articles in the stem cell field could identify milestones and important contributors, giving a historic perspective on scientific progress.

    Citation analysis has been neglected in suicidology. The present note applies a mixed-methods approach to both test and suggest hypotheses for the variation in article impact in the bereavement literature. One hundred three articles from three core suicidology journals met the criteria for inclusion in the investigation. Citations to the articles were obtained from the Web of Science. Predictor variables included structural characteristics of the author (e.g., gender) and the article itself (e.g., years since publication). A multivariate regression analysis determined that, controlling for the other variables, the most important predictor of citations was the review article (β = .461), followed by year of publication (β = -.414), the multiauthored article (β = .302), publication in Suicide and Life-Threatening Behavior (SLTB) (β = .161), and male gender (β = .156). The 12 most cited articles were published between 1979 and 2004 in SLTB. The majority of these papers was written by males, were U.S. authors, and had more than one author. Four of the most cited articles were reviews. The study concludes that structural characteristics of articles and authors explained 41% of the variance in citations. The qualitative analysis determined that review papers, and papers on characteristics of suicide bereavement and psychological autopsies have been most frequently cited. Replication studies are needed for other subfields of suicidology. © 2014 The American Association of Suicidology.

  1. Metabolic chemotypes of CITES protected Dalbergia timbers from Africa, Madagascar, and Asia.

    The genus Dalbergia includes approximately 250 species worldwide. Of these, 58 species are of economic importance and listed under CITES. Identification of illegal transnational timber trade is a challenge because logs or boards lack the typical descriptors used for species identification such as leaves and flowers; therefore, frequently the lowest taxonomic determination of these tree byproducts is genus. In this study, we explore the use of Direct Analysis in Real Time (DART) Time-Of-Flight Mass Spectrometry (TOFMS) in making species determinations of protected Dalbergia trees from Africa, Madagascar, and Asia. Metabolic profiles were collected using DART TOFMS from the heartwood of seven species and the sapwood of 17 species of Dalbergia. Also included in this study are 85 Dalbergia heartwood samples from Madagascar that were only identified to genus. In all, 21 species comprising 235 specimens were analyzed, the metabolic chemotypes were interpreted, and the spectra were analyzed using chemometric tools. Dalbergia cochinchinensis and Dalbergia spp. from Madagascar (both CITES Appendix II) could be differentiated from each other and from the non-protected Dalbergia latifolia and Dalbergia melanoxylon. DART TOFMS is a valuable high-throughput tool useful for making phytochemical classifications of Dalbergia spp. The data produced allows the protected Dalbergias from Madagascar to be distinguished and can differentiate closely related rosewood trees. Published in 2015. This article is a U.S. Government work and is in the public domain in the USA.

  2. Medicinal wild plant knowledge and gathering patterns in a Mapuche community from North-western Patagonia.

    2006-01-03

    Medicinal plant use has persisted as a long standing tradition in the Mapuche communities of Southern Argentina and Chile. An ethnobotanical survey was conducted in the rural Curruhuinca community located near the mountain city of San Martin de los Andes, Argentina. Semi-structured interviews were carried out on 22 families in order to examine the present use of medicinal plants and their reputed therapeutic effects. Ecological variables, such as distance to the gathering site and biogeographical origin were also analyzed. Our results showed that the Curruhuinca dwellers cited 89 plant species for medicinal purposes, both of native and exotic origin. They know about 47 native plants, of which they use 40, and they know of 42 exotic medicinal plants of which they use 34. A differential pattern was observed given that only native species, relevant for the traditional Mapuche medicine, were collected at more distant gathering sites. The interviewees mentioned 268 plant usages. Those most frequently reported had therapeutic value for treating digestive ailments (33%), as analgesic/anti-inflammatory (25%) and antitusive (13%). Native species were mainly cited as analgesics, and for gynecological, urinary and "cultural syndrome" effects, whereas exotic species were mainly cited for digestive ailments. The total number of medicinal plants known and used by the interviewees was positively correlated with people's age, indicating that this ancient knowledge tends to disappear in the younger generations.

    2008-01-01

    We examined and compared the illness beliefs of South Asian and European patients with coronary heart disease (CHD) about causal attributions and lifestyle change. This was a qualitative study that used framework analysis to examine in-depth interviews. The study comprised 65 subjects (20 Pakistani-Muslim, 13 Indian-Hindu, 12 Indian-Sikh, and 20 Europeans) admitted to one of three UK sites within the previous year with unstable angina or myocardial infarction, or to undergo coronary artery bypass surgery. Beliefs about CHD cause varied considerably. Pakistani-Muslim participants were the least likely to report that they knew what had caused their CHD. Stress and lifestyle factors were the most frequently cited causes for CHD irrespective of ethnic grouping, although family history was frequently cited by older European participants. South Asian patients were more likely to stop smoking than their European counterparts but less likely to use audiotape stress-relaxation techniques. South Asian patients found it particularly difficult to make dietary changes. Some female South Asians developed innovative indoor exercise regimens to overcome obstacles to regular exercise. Misconceptions about the cause of CHD and a lack of understanding about appropriate lifestyle changes were evident across ethnic groups in this study. The provision of information and advice relating to cardiac rehabilitation must be better tailored to the context of the specific needs, beliefs, and circumstances of patients with CHD, regardless of their ethnicity.

    Zborowsky, Terri

    2014-01-01

    The purpose of this paper is to explore nursing research that is focused on the impact of healthcare environments and that has resonance with the aspects of Florence Nightingale's environmental theory. Nurses have a unique ability to apply their observational skills to understand the role of the designed environment to enable healing in their patients. This affords nurses the opportunity to engage in research studies that have immediate impact on the act of nursing. Descriptive statistics were performed on 67 healthcare design-related research articles from 25 nursing journals to discover the topical areas of interest of nursing research today. Data were also analyzed to reveal the research designs, research methods, and research settings. These data are part of an ongoing study. Descriptive statistics reveal that topics and settings most frequently cited are in keeping with the current healthcare foci of patient care quality and safety in acute and intensive care environments. Research designs and methods most frequently cited are in keeping with the early progression of a knowledge area. A few assertions can be made as a result of this study. First, education is important to continue the knowledge development in this area. Second, multiple method research studies should continue to be considered as important to healthcare research. Finally, bedside nurses are in the best position possible to begin to help us all, through research, understand how the design environment impacts patients during the act of nursing.

    Background. While rates of advance care documentation amongst the general public remain low, there is increasing recognition of the value of informal planning to address patient preferences in serious illness. Objectives. To determine the associations between personal attributes and formal and informal planning for serious illness across age groups. Methods. This population-based, online survey was conducted in Saskatchewan, Canada, in April, 2012, using a nonclinical sample of 827 adults ranging from 18 to 88 years of age and representative of age, sex, and regional distribution of the province. Associations between key predictor variables and planning for serious illness were assessed using binary logistic regression. Results. While 16.6% of respondents had completed a written living will or advance care plan, half reported having conversations about their treatment wishes or states of health in which they would find it unacceptable to live. Lawyers were the most frequently cited source of assistance for those who had prepared advance care plans. Personal experiences with funeral planning significantly increased the likelihood of activities designed to plan for serious illness. Conclusions. Strategies designed to increase the rate of planning for future serious illness amongst the general public must account for personal readiness. PMID:25025030

  13. On the definition and identifiability of the alleged "hiatus" in global warming.

    2015-11-24

    Recent public debate and the scientific literature have frequently cited a "pause" or "hiatus" in global warming. Yet, multiple sources of evidence show that climate change continues unabated, raising questions about the status of the "hiatus". To examine whether the notion of a "hiatus" is justified by the available data, we first document that there are multiple definitions of the "hiatus" in the literature, with its presumed onset spanning a decade. For each of these definitions we compare the associated temperature trend against trends of equivalent length in the entire record of modern global warming. The analysis shows that the "hiatus" trends are encompassed within the overall distribution of observed trends. We next assess the magnitude and significance of all possible trends up to 25 years duration looking backwards from each year over the past 30 years. At every year during the past 30 years, the immediately preceding warming trend was always significant when 17 years (or more) were included in the calculation, alleged "hiatus" periods notwithstanding. If current definitions of the "pause" used in the literature are applied to the historical record, then the climate system "paused" for more than 1/3 of the period during which temperatures rose 0.6 K.

    1982-06-01

    A nationwide telephone survey of 1,223 individuals investigated the nature and source of information provided to patients regarding prescription drugs. About half of the respondents said that they had received information from their doctor about the purpose and directions for use for their most recent prescription. Only a few people (11 per cent) said that they had been informed about the drug's side effects and 19 per cent said that they had been told nothing by their doctor. Most (72 per cent) related that nothing had been said to them at the pharmacy. Written information (stickers on the medicine container,more » leaflets or brochures) were said to be infrequently provided at the pharmacy. About 12 per cent of the respondents said they had expected they might get a drug side effect, but only 9 per cent said that they had experienced one. The most frequently cited action in response to side effects was to consult the physician (40 per cent); however, a sizeable percentage of people stopped the medicine completely or temporarily (36 per cent) or kept on taking the drug as prescribed (32 per cent).« less

    South America holds 30% of the world's avifauna, with the Atlantic Forest representing one of the richest regions of the Neotropics. Here we have compiled a data set on Brazilian Atlantic Forest bird occurrence (150,423) and abundance samples (N = 832 bird species; 33,119 bird individuals) using multiple methods, including qualitative surveys, mist nets, point counts, and line transects). We used four main sources of data: museum collections, on-line databases, literature sources, and unpublished reports. The data set comprises 4,122 localities and data from 1815 to 2017. Most studies were conducted in the Florestas de Interior (1,510 localities) and Serra do Mar (1,280 localities) biogeographic sub-regions. Considering the three main quantitative methods (mist net, point count, and line transect), we compiled abundance data for 745 species in 576 communities. In the data set, the most frequent species were Basileuterus culicivorus, Cyclaris gujanensis, and Conophaga lineata. There were 71 singletons, such as Lipaugus conditus and Calyptura cristata. We suggest that this small number of records reinforces the critical situation of these taxa in the Atlantic Forest. The information provided in this data set can be used for macroecological studies and to foster conservation strategies in this biodiversity hotspot. No copyright restrictions are associated with the data set. Please cite this Data Paper if data are used in publications and teaching events. © 2017 by the Ecological Society of America.

  16. Measurements of atmospheric dimethylsulfide, hydrogen sulfide, and carbon disulfide during GTE/CITE 3

    NASA Technical Reports Server (NTRS)

    Cooper, David J.; Saltzman, Eric S.

    1993-01-01

    Measurements of atmospheric dimethylsulfide (DMS), hydrogen sulfide (H2S), and carbon disulfide (CS2) were made over the North and South Atlantic Ocean as part of the Global Tropospheric Experiment/Chemical Instrumentation Test and Evaluation (GTE/CITE 3) project. DMS and CS2 samples were collected and analyzed using an automated gas chromatography/flame photometric detection system with a sampling frequency of 10 min. H2S samples were collected using silver nitrate impregnated filters and analyzed by fluorescence quenching. The DMS data from both hemispheres have a bimodal distribution. Over the North Atlantic this reflects the difference between marine and continental air masses. Over the South Atlantic it may reflect differences in the sea surface source of DMS, corresponding to different air mass source regions. The median boundary layer H2S and CS2 levels were significantly higher in the northern hemisphere than the southern hemisphere, reflecting the higher frequency of samples influenced by pollutant and/or coastal emissions. Composite vertical profiles of DMS and H2S are similar to each other, are consistent with a sea surface source. Vertical profiles of CS2 have maxima in the free troposphere, implicating a continental source. The low levels of H2S and CS2 found in the southern hemisphere constrain the role of these compounds in global budgets to significantly less than previously estimated.

    To examine the personal domains multiple mini interviews (MMIs) are being designed to assess, explore how they were determined and contextualise such domains in current and future healthcare student selection processes DESIGN: A systematic review of empirical research reporting on MMI model design was conducted from database inception to November 2017. Twelve electronic bibliographic databases. Evidence was extracted from original studies, and integrated in a narrative synthesis guided by the PRISMA statement for reporting systematic reviews. Personal domains were clustered into themes using a modified Delphi technique. A total of 584 articles were screened. 65 unique studies (80 articles) matched our inclusion criteria of which seven were conducted within nursing/midwifery faculties. Six in 10 studies featured applicants to medical school. Across selection processes, we identified 32 personal domains assessed by MMIs, the most frequent being: communication skills (84%), teamwork/collaboration (70%), and ethical/moral judgement (65%). Domains capturing ability to cope with stressful situations (14%), make decisions (14%), and resolve conflict in the workplace (13%) featured in fewer than ten studies overall. Intra- and inter-disciplinary inconsistencies in domain profiles were noted, as well as differences by entry level. MMIs deployed in nursing and midwifery assessed compassion and decision-making more frequently than in all other disciplines. Own programme philosophy and professional body guidance were most frequently cited (~50%) as sources for personal domains; a blueprinting process was reported in only 8% of studies. Nursing, midwifery and allied healthcare professionals should develop their theoretical frameworks for MMIs to ensure they are evidence-based and fit-for-purpose. We suggest a re-evaluation of domain priorities to ensure that students who are selected, not only have the capacity to offer the highest standards of care provision, but are able to maintain these standards when facing clinical practice and organisational pressures.

    International wildlife trade is one of the leading threats to biodiversity conservation. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is the most important initiative to monitor and regulate the international trade of wildlife but its credibility is dependent on the quality of the trade data. We report on the performance of CITES reporting by focussing on the commercial trade in non-native reptiles and amphibians into Thailand as to illustrate trends, species composition and numbers of wild-caught vs. captive-bred specimens. Based on data in the WCMC-CITES trade database, we establish that a total of 75,594 individuals of 169 species of reptiles and amphibians (including 27 globally threatened species) were imported into Thailand in 1990-2007. The majority of individuals (59,895, 79%) were listed as captive-bred and a smaller number (15,699, 21%) as wild-caught. In the 1990s small numbers of individuals of a few species were imported into Thailand, but in 2003 both volumes and species diversity increased rapidly. The proportion of captive-bred animals differed greatly between years (from 0 to >80%). Wild-caught individuals were mainly sourced from African countries, and captive-bred individuals from Asian countries (including from non-CITES Parties). There were significant discrepancies between exports and imports. Thailand reports the import of >10,000 individuals (51 species) originating from Kazakhstan, but Kazakhstan reports no exports of these species. Similar discrepancies, involving smaller numbers (>100 individuals of 9 species), can be seen in the import of reptiles into Thailand via Macao. While there has been an increase in imports of amphibian and reptiles into Thailand, erratic patterns in proportions of captive-bred specimens and volumes suggests either capricious markets or errors in reporting. Large discrepancies with respect to origin point to misreporting or possible violations of the rules and intentions of CITES.

    Mixtures of internationally traded organic substances can contain parts of species protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). These mixtures often raise the suspicion of border control and customs offices, which can lead to confiscation, for example in the case of Traditional Chinese medicines (TCMs). High-throughput sequencing of DNA barcoding markers obtained from such samples provides insight into species constituents of mixtures, but manual cross-referencing of results against the CITES appendices is labor intensive. Matching DNA barcodes against NCBI GenBank using BLAST may yield misleading results both as false positives, due to incorrectly annotated sequences, and false negatives, due to spurious taxonomic re-assignment. Incongruence between the taxonomies of CITES and NCBI GenBank can result in erroneous estimates of illegal trade. The HTS barcode checker pipeline is an application for automated processing of sets of 'next generation' barcode sequences to determine whether these contain DNA barcodes obtained from species listed on the CITES appendices. This analytical pipeline builds upon and extends existing open-source applications for BLAST matching against the NCBI GenBank reference database and for taxonomic name reconciliation. In a single operation, reads are converted into taxonomic identifications matched with names on the CITES appendices. By inclusion of a blacklist and additional names databases, the HTS barcode checker pipeline prevents false positives and resolves taxonomic heterogeneity. The HTS barcode checker pipeline can detect and correctly identify DNA barcodes of CITES-protected species from reads obtained from TCM samples in just a few minutes. The pipeline facilitates and improves molecular monitoring of trade in endangered species, and can aid in safeguarding these species from extinction in the wild.

    Commercial trade of wild birds may devastate wild bird populations. Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) controls the trade of wild species listed in its appendices to avoid these species being threatened by international trade. China used to be one of the major trading countries with significant bird trade with foreign countries; on the other hand, China is a country with unique avian fauna, many Important Bird Areas and critically endangered bird species. What is the role of the country in world wild bird trade? What kind of insights can we extract from trade records for improving future management of wild bird trade in the country? We retrieved and analyzed international trade records of the CITES listed bird species of China from 1981 to 2010 from the CITES Trade Database maintained by United Nations Environment Program and World Conservation Monitoring Centre (UNEP-WCMC). We found that: (1) International trade of live birds in China peaked during the late 1990s, then decreased to the level before the surge of trade in a few years, the trade dynamics of wild birds may be affected by governmental policy and the outbreak of avian influenza during the period. (2) Most frequently traded CITES Appendix listed birds in China were parrots, most of which were exotic species to the country. (3) Birds were mainly traded for commercial purpose. Exotic birds in trade were mainly captive-bred while the most Chinese birds traded internationally were captured from the wild. Since many bird species in international trade are threatened to extinction, China should take stricter measures on importing of wild-captured birds and should collaborate with the countries of original in the international bird trade to avoid unsustainable harvesting of wild birds. It is urgent for China to carry out population surveys on those domestic bird species once in significant international trade and to make better conservation decisions based on population status of those birds. In addition, more scientific researchers should be encouraged to participate in the wildlife trade management to avoid misreporting trade data or biased analyses of the trade records.

    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

  5. Review and bibliometric analysis of published literature citing data produced by the Gap Analysis Program (GAP)

    The Gap Analysis Program (GAP) of the U.S. Geological Survey (USGS) produces geospatial datasets providing information on land cover, predicted species distributions, stewardship (ownership and conservation status), and an analysis dataset which synthesizes the other three datasets. The intent in providing these datasets is to support the conservation of biodiversity. The datasets are made available at no cost. The initial datasets were created at the state level. More recent datasets have been assembled at regional and national levels. GAP entered an agreement with the Policy Analysis and Science Assistance branch of the USGS to conduct an evaluation to describe the effect that using GAP data has on those who utilize the datasets (GAP users). The evaluation project included multiple components: a discussion regarding use of GAP data conducted with participants at a GAP conference, a literature review of publications that cited use of GAP data, and a survey of GAP users. The findings of the published literature search were used to identify topics to include on the survey. This report summarizes the literature search, the characteristics of the resulting set of publications, the emergent themes from statements made regarding GAP data, and a bibliometric analysis of the publications. We cannot claim that this list includes all publications that have used GAP data. Given the time lapse that is common in the publishing process, more recent datasets may be cited less frequently in this list of publications. Reports or products that used GAP data may be produced but never published in print or released online. In that case, our search strategies would not have located those reports. Authors may have used GAP data but failed to cite it in such a way that the search strategies we used would have located those publications. These are common issues when using a literature search as part of an evaluation project. Although the final list of publications we identified is not comprehensive, this set of publications can be considered a sufficient sample of those citing GAP data and suitable for the descriptive analyses we conducted.

    As part of a study to develop effective Internet-based HIV prevention interventions for Men who use the Internet to seek Sex with Men (MISM), we sought information from the target population on (a) acceptability of sexually explicit media; (b) interest in specific content areas; and (c) identification of credible sources of information. A cross-sectional stratified Internet-based survey design was employed. Between September and November 2005, we recruited 2,716 MISM through Gay.com stratified across race/ethnicity to ensure adequate racial/ethnic diversity. Sixteen Likert-type items assessed acceptability of sexual explicitness, 24 items identified topics for inclusion, and two assessed sources of information. There was near universal acceptability for highly sexually explicit education. Over 75 percent reported high interest in ten sexual health topics. HIV positive MISM and MISM engaged in unprotected anal sex with multiple male partners reported significantly less interest in HIV prevention specific content. Differences across age, race/ethnicity and education were identified. Idiosyncratic searches and gay sites were frequently cited sources of information; however blogs, government, and media sites were not. It is acceptable for web-based HIV prevention for MISM to be highly sexually explicit and to provide detailed content relevant to men's sexual health. Since demographic differences in acceptability and content were minor, it is appropriate for interventions to target across demographics. Interventions to re-engage men engaging in high risk and HIV+ MISM should be considered. Leading health agencies should review whether their web information is retrievable, credible and useful to those most at risk. PMID:18401701

    The objective of the Aviation System Monitoring and Modeling (ASMM) project of NASA s Aviation Safety and Security Program was to develop technologies that will enable proactive management of safety risk, which entails identifying the precursor events and conditions that foreshadow most accidents. This presents a particular challenge in the aviation system where people are key components and human error is frequently cited as a major contributing factor or cause of incidents and accidents. In the aviation "world", information about what happened can be extracted from quantitative data sources, but the experiential account of the incident reporter is the best available source of information about why an incident happened. This report describes a conceptual model and an approach to automated analyses of textual data sources for the subjective perspective of the reporter of the incident to aid in understanding why an incident occurred. It explores a first-generation process for routinely searching large databases of textual reports of aviation incident or accidents, and reliably analyzing them for causal factors of human behavior (the why of an incident). We have defined a generic structure of information that is postulated to be a sound basis for defining similarities between aviation incidents. Based on this structure, we have introduced the simplifying structure, which we call the Scenario as a pragmatic guide for identifying similarities of what happened based on the objective parameters that define the Context and the Outcome of a Scenario. We believe that it will be possible to design an automated analysis process guided by the structure of the Scenario that will aid aviation-safety experts to understand the systemic issues that are conducive to human error.

  8. Information sources used by parents buying non-prescription medicines in pharmacies for preschool children.

    Parents are exposed to many different information sources about children's medicines, including recommendations from other people, the media, and their own previous experience. The aim of this paper is to explore the influence of different information sources upon their non-prescription medicine purchases for children aged 0-4 years. The setting was thirty-nine community pharmacies across four Primary Care Trusts in England. We explored the type and range of information sources used by parents in purchasing non-prescription medicines. Methods A self-completion survey and a subset of semi-structured telephone interviews were undertaken with parents/carers buying oral medicines for children aged 0-4 years. One hundred and thirty-four surveys and thirty-eight interviews were completed: most participants were 25-44 year-old women. Recommendations from other people, both from health professionals and family members, were most often cited as influencing parents' and carers' choice of medicine. Advertising, and well-known brands of children's medicines, were also influential. The Internet and other media were less often cited as sources. Medicines leaflets and packaging were found to be useful: a significant minority admitted difficulty in understanding all the information therein. This study explored the information sources reported at the point of a specific medicine purchase, thus reflecting actual behaviour rather than general perceptions of useful sources. Parents and carers of pre-school children reported a number of professional and lay influences on their medicine purchase choices. Pharmacists and staff should consider these influences when advising children's medicine purchasers. A combination of spoken advice and written reminder information would meet the preferences of most purchasers.

    2014-01-01

    According to The Joint Commission (TJC), the most frequently cited root cause of sentinel events is ineffective communication or miscommunication (TJC, 2002, 2012). The need to improve communication among health care professionals is a high priority because of the serious consequences of poor communication for everyone involved, on both personal and corporate levels. Applied improvisational exercises (AlEs) comprise a strategy for enhancing interprofessional communication (IPC). This article asks: What are the challenges inherent in IPC and teambuilding in the health care setting, and how can AIE help bridge the communication gap?

    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.

  13. Betweenness and diversity in journal citation networks as measures of interdisciplinarity-A tribute to Eugene Garfield.

    PubMed

    Leydesdorff, Loet; Wagner, Caroline S; Bornmann, Lutz

    2018-01-01

    Journals were central to Eugene Garfield's research interests. Among other things, journals are considered as units of analysis for bibliographic databases such as the Web of Science and Scopus. In addition to providing a basis for disciplinary classifications of journals, journal citation patterns span networks across boundaries to variable extents. Using betweenness centrality (BC) and diversity, we elaborate on the question of how to distinguish and rank journals in terms of interdisciplinarity. Interdisciplinarity, however, is difficult to operationalize in the absence of an operational definition of disciplines; the diversity of a unit of analysis is sample-dependent. BC can be considered as a measure of multi-disciplinarity. Diversity of co-citation in a citing document has been considered as an indicator of knowledge integration, but an author can also generate trans-disciplinary-that is, non-disciplined-variation by citing sources from other disciplines. Diversity in the bibliographic coupling among citing documents can analogously be considered as diffusion  or differentiation of knowledge across disciplines. Because the citation networks in the cited direction reflect both structure and variation, diversity in this direction is perhaps the best available measure of interdisciplinarity at the journal level. Furthermore, diversity is based on a summation and can therefore be decomposed; differences among (sub)sets can be tested for statistical significance. In the appendix, a general-purpose routine for measuring diversity in networks is provided.

    This investigation was made to reveal the current status, research trend and research level of biomedical engineering in Chinese mainland by means of scientometrics and to assess the quality of the four domestic publications by bibliometrics. We identified all articles of four related publications by searching Chinese and foreign databases from 1997 to 2001. All articles collected or cited by these databases were searched and statistically analyzed for finding out the relevant distributions, including databases, years, authors, institutions, subject headings and subheadings. The source of sustentation funds and the related articles were analyzed too. The results showed that two journals were cited by two foreign databases and five Chinese databases simultaneously. The output of Journal of Biomedical Engineering was the highest. Its quantity of original papers cited by EI, CA and the totality of papers sponsored by funds were higher than those of the others, but the quantity and percentage per year of biomedical articles cited by EI were decreased in all. Inland core authors and institutions had come into being in the field of biomedical engineering. Their research topics were mainly concentrated on ten subject headings which included biocompatible materials, computer-assisted signal processing, electrocardiography, computer-assisted image processing, biomechanics, algorithms, electroencephalography, automatic data processing, mechanical stress, hemodynamics, mathematical computing, microcomputers, theoretical models, etc. The main subheadings were concentrated on instrumentation, physiopathology, diagnosis, therapy, ultrasonography, physiology, analysis, surgery, pathology, method, etc.

    This study reports on the Brazilian experience of developing a specialized bulletin, the Brazilian Health Technology Assessment Bulletin (BRATS), on health technology assessments (HTA). The editorial process, format, and dissemination strategy of the publication are presented. A critical appraisal of the available issues was made using the checklist for HTA reports of the International Network of Agencies for Health Technology Assessment. The initial impact was estimated based on a retrospective observational measurement of the types of publications that cite the bulletin as a source of information. The publications citing BRATS were identified using Google Scholar. Since June 2008, fourteen issues of the bulletin have been produced. BRATS has not presented any significant limitation that would compromise generalizations of its results within the Brazilian context. The initial impact of the bulletin, however, has been small, which may be due to its exclusively electronic dissemination format and technical language. We found nine publications citing BRATS in Google Scholar. It is hoped that the bulletin will promote the continuity of HTA actions among health-sector managers and professionals in Brazil.

  16. Propagation of erroneous data for the modulus of elasticity of periodontal ligament and gutta percha in FEM/FEA papers: a story of broken links.

    PubMed

    Ruse, N Dorin

    2008-12-01

    This brief review essay was triggered by the discovery of two errors that have been perpetuated in the dental literature for the last quarter century and is intended to alert the research community. An extensive search of the published literature, using PubMed and Web of Science search engines, electronic journal resources, and several trips to the library for manual retrievals of articles were used to retrieve hundreds of articles reporting on finite element modeling - finite element analysis (FEM/FEA) involving periodontal ligament (PDL) and gutta percha (GP). The literature search revealed that erroneous values for the modulus of elasticity of PDL and GP were introduced in 1980 and in 1983, respectively. The identified errors range between two to three orders of magnitude and have been used in hundreds of FEM/FEA papers. The finding casts serious doubts regarding the validity of the results published in hundreds of papers and highlights the importance of checking the references cited and citing, or at least confirming, primary sources rather than citing citations.

    Traditional commercial bibliographic databases and indexes provide some access to hydrology materials produced by the government; however, these sources do not provide comprehensive coverage of relevant hydrologic publications. This paper discusses bibliographic information available from the federal government and state geological surveys, water resources agencies, and depositories. In addition to information in these databases, the paper describes the scope, styles of citing, subject terminology, and the ways these information sources are currently being searched, formally and informally, by hydrologists. Information available from the federal and state agencies and from the state depositories might be missed by limiting searches to commercially distributed databases.

    Bibliometric studies are increasingly being utilized as a tool for gauging the impact of different literature within a given field. The purpose of this study was to identify the most cited articles related to the management of distal radius fractures to better understand how the evidence of this topic has been shaped and changed over time. We utilized the ISI web of science database to conduct a search for the term "distal radius fracture" under the "orthopaedics" research area heading, and sorted the results by number of times cited. The 100 most cited articles published in orthopedic journals were then analyzed for number of citations, source journal, year of publication, number of authors, study type, level of evidence, and clinical outcomes utilized. The 100 most cited articles identified were published between 1951 and 2009. Total number of citations ranged between 525 and 67, and came from ten different orthopedic journals. The largest number of articles came from J Hand Surg Am and J Bone Joint Surg Am, each with 32. Consistent with previous analyses of orthopedic literature, the articles were primarily clinical, and of these, 53/76 were case series. The vast majority were evidence level IV. Only a small percentage of articles utilized patient reported outcome measures. These data show that despite distal radius fractures being a common fracture encountered by physicians, very few of the articles were high quality studies, and only a low proportion of the studies include patient reported outcome measures. Surgeons should take this lack of high-level evidence into consideration when referencing classic papers in this field. Analysis of the 100 most cited distal radius fracture articles allows for delineation of which articles are most common in the field and if a higher level of evidence correlates positively with citation quantity.

    To identify and analyze the 50 most-cited gastroenterology and hepatology articles originating from mainland China. We utilized the 2015 edition of Journal Citation Reports and PubMed to determine the 50 most-cited gastroenterology and hepatology articles from 75 professional journals and four leading journals in clinical medicine, which are The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, and The British Medical Journal. Then we excluded the articles written outside mainland China and collected the basic information, including the title, authors, year of publication, source journal, city, institution, number of citations, and topic of the research. The number of citations for the top 50 papers ranged from 279 to 89 (mean, 129). These articles were published between 2005 and 2012, in which 2009 was the year with the largest number of highly cited papers(13). All articles were published in 15 journals. The journal Hepatology published the largest number of articles(21), followed by Journal of Gastroenterology and Hepatology(4), Journal of Hepatology(4) and World Journal of Gastroenterology(4). The top 50 articles originated mainly from Shanghai(20), Guangzhou(13) and Beijing(6). Sun Yat-sen University produced most highly cited papers(10). The number of basic research was far more than clinical research, of which the ratio was about 1.78(32:18). In all these articles, hepatocellular carcinoma was the most-discussed topic(19), followed by hepatitis B virus(8) and endoscopic(5). Although a large gap remains between mainland China and the global community, the gastroenterology and hepatology research from China is gradually recognized by the world.

    The impact of a publication in a particular medical area is reflected by the number of times the article is included as a citation. It is not known, however, which articles are cited the most in primary care journals. In our study, we aimed to identify the 100 most cited articles in primary care medicine and analyze their characteristics.We searched the Science Citation Index Expanded for articles published in 18 primary care journals using the subject category "Primary health care." We identified 100 articles in primary health care that were the most cited. We analyzed the characteristics of these articles using the title, number of citations, citation density, year of publication, journal source, decade published, country of origin, institution, author names, and type of article.The 100 articles that were cited the most were published between the years 1977 and 2009. The 1990s decade was the most productive decade. The number of citations ranged from 117 to 775. The articles were published in 9 journals and the journal with the largest number of most cited articles (n = 33) was the Journal of Family Practice. This was followed by the British Journal of General Practice (n = 17) and the journal Family Practice (n = 16). The United States was the most productive country (n = 59); the United Kingdom was next (n = 25) and this was followed by Canada (n = 5) and The Netherlands (n = 5). The most popular article type was a review article and this was followed by a qualitative study and then methodological study.Our study provides insight into the historical development of primary care studies, based on citations, and provides the foundation for further investigations.
